CP

Child pornography, commonly abbreviated as CP, consists of any visual depiction—including photographs, films, videos, pictures, or computer-generated images—of sexually explicit conduct involving a person under the age of eighteen, where "sexually explicit conduct" encompasses actual or simulated , bestiality, , sadistic or masochistic , or lascivious exhibition of genitals or pubic area. Such material qualifies as a form of sexual , with production frequently entailing direct , enticement, or of minors to generate the content. Unlike general , CP lacks First Amendment protection in the United States due to its inherent documentation or simulation of harm, rendering its creation, distribution, receipt, or possession federally criminalized offenses punishable by lengthy imprisonment and fines. Federal statutes originated in the Protection of Children Against Sexual Exploitation Act of 1977, marking the first comprehensive U.S. prohibition on production, with subsequent amendments addressing technological advances like and transmission to close loopholes for morphed or virtual depictions lacking actual minors. The internet's expansion since the has exponentially increased CP's accessibility and volume, shifting much production and exchange to covert networks while complicating enforcement through and sharing. Key controversies center on definitional boundaries and penalties: debates persist over excluding non-realistic drawings or writings unless they lack serious value and appeal to prurient interest, as affirmed in legal precedents distinguishing exploitative visuals from protected expression; self-produced images by minors blur victim-perpetrator lines, raising questions of criminalizing adolescent behavior; and sentencing guidelines for mere —often 5–20 years—have drawn criticism for disproportionality relative to contact offenses, amid empirical variances in possessors' risks compared to hands-on abusers. These issues underscore tensions between absolute safeguards and evidentiary thresholds for harm causation, with some analyses noting institutional tendencies—such as in academic or advocacy circles—to prioritize procedural critiques over the material's perpetuation of demand-driven abuse cycles.

Science and Technology

Biology and Medicine

(CP) denotes a group of non-progressive neurological disorders originating from disturbances in the development of the fetal or infant brain, resulting in impaired movement, posture, and motor function that typically emerge in . These disturbances lead to symptoms such as , , , or flaccid weakness, with severity ranging from mild coordination issues to profound requiring lifelong support. CP affects , reflexes, and coordination but does not worsen over time, distinguishing it from degenerative conditions. The global birth prevalence of CP stands at approximately 1.6 cases per 1,000 live births, with higher rates in low- and middle-income countries due to factors like preterm delivery and infections. An estimated 18 million individuals worldwide live with CP, representing the most common motor in childhood. In high-income settings, prevalence has declined by about 25% over recent decades, attributed to improvements in neonatal . Brain insults causing CP occur predominantly prenatally (85-90% of cases), with fewer perinatal (5-10%) or postnatal origins; common etiologies include vascular disruptions, , genetic anomalies, and malformations rather than isolated birth , which accounts for under 10% of cases despite historical emphasis. Risk factors encompass maternal , multiple , placental abnormalities, and before 32 weeks, which elevates incidence to 50-100 per 1,000. Genetic contributions are limited, implicated in roughly 2% of cases via mutations affecting brain development. Classification divides CP into four primary types based on predominant motor impairment: (70-80% of cases, featuring increased muscle tone and joint contractures), dyskinetic (involuntary writhing or jerky movements from damage), ataxic (poor balance and coordination from cerebellar involvement), and mixed (combining features of the others). Subtypes like hemiplegic or diplegic specify affected body regions. relies on clinical , (e.g., MRI revealing ), and developmental assessments, often confirmed by age 2. No curative interventions exist for CP, as the underlying is irreversible; management targets symptom alleviation and functional optimization. Physical and occupational therapies enhance mobility and daily skills, starting in infancy to leverage . Pharmacologic options include or for , anticonvulsants for seizures (affecting 30-50% of cases), and for alignment. Surgical procedures, such as selective dorsal or lengthening, address contractures in severe cases. Multidisciplinary care improves , with early intervention reducing secondary complications like or . Beyond , CP abbreviates , a copper-binding ferroxidase encoded by the CP gene on , essential for and deficient in aceruloplasminemia, a rare neurodegenerative disorder. In , CP refers to coat proteins forming viral capsids that protect genomic material and facilitate host cell entry. , a byproduct of , serves as a for endogenous insulin production in assessment. These usages, while precise, lack the clinical prominence of in medical contexts.

Chemistry

In physical chemistry and thermodynamics, C_p denotes the heat capacity at constant pressure, defined as the quantity of heat required to raise the temperature of a given amount of substance by 1 kelvin while pressure remains constant. For one mole of substance, this is the molar heat capacity C_p, which for ideal gases satisfies C_p = C_v + R, where C_v is the molar heat capacity at constant volume and R is the universal gas constant (8.314 J/mol·K). This parameter is essential for calculating enthalpy changes in processes like isobaric expansions or reactions, as enthalpy H = U + pV yields \Delta H = \int C_p \, dT for constant-pressure conditions./17%3A_Thermochemistry/17.04%3A_Heat_Capacity_and_Specific_Heat) In , Cp refers to the cyclopentadienyl ligand (\ce{C5H5^-}), a five-membered aromatic anion that coordinates to transition metals primarily in an \eta^5-binding mode, donating all five carbon electrons to form stable \pi-complexes./09%3A_Complexes_of_bound_Ligands/9.03%3A_Metal_Cyclopentadienyl_Complexes) This ligand's electron-rich, fluxional nature enables its use in catalysts for olefin (e.g., zirconocene systems) and in iconic compounds like (\ce{(C5H5)2Fe}), whose 1951 structural elucidation by revealed the metallocene sandwich motif and spurred advancements in the field. Variations such as pentamethylcyclopentadienyl (Cp*) enhance steric bulk and solubility for specialized applications. CP also designates the "chemically pure" grade for laboratory s, signifying a baseline purity (often >95%) adequate for routine syntheses and educational purposes, though lacking the certified assays of higher grades like analytical (AR) or ACS. Such labeling prioritizes cost-effectiveness over , distinguishing it from technical grades unsuitable for precise analytical work.

Computing

CP/M (Control Program for Microcomputers) was the first commercially successful operating system for microcomputers, developed by of in 1974. It ran on and Z80 processors, requiring as little as 20 KB of , and facilitated file management and program execution on disk-based systems, influencing early personal computing before dominated in the . By 1982, powered thousands of systems from vendors like and , establishing standards for command-line interfaces and portability across hardware. Constraint programming (CP) is a declarative for modeling and solving problems, where variables, domains, and constraints are specified, and solvers propagate constraints to prune search spaces and find feasible solutions. Originating from and research in the 1970s–1980s, it excels in applications like scheduling, rostering, and , often outperforming exhaustive search in domains by leveraging techniques such as consistency and . Modern CP solvers, integrated with tools, handle real-world problems in industries including and , as seen in Google's CP-SAT solver released in updates through 2024. Competitive programming (CP), also known as sport programming, involves participants writing code to solve algorithmic problems under strict time limits, typically 1–5 hours per contest, emphasizing efficiency in time and . It traces roots to events like the ACM (ICPC), formalized in 1977, and platforms such as and , which host millions of submissions annually. Participants use languages like C++ or to implement data structures and algorithms for problems in , dynamic programming, and sorting, fostering skills transferable to interviews at firms like and . As of 2025, CP remains integral to curricula, with resources like the Competitive Programmer's Handbook aiding preparation for global rankings and job placements.

Mathematics

In mathematics, CP primarily denotes complex projective space \mathbb{CP}^n, the standard n-dimensional over the complex numbers \mathbb{C}. It is constructed as the quotient space \mathbb{C}^{n+1} \setminus \{0\} / \sim, where \sim identifies points differing by nonzero complex , equivalently parameterizing lines through the origin in \mathbb{C}^{n+1}. This space is a compact, connected of complex dimension n, equipped with the Fubini-Study Kähler metric, making it a canonical example in . \mathbb{CP}^n admits homogeneous coordinates [z_0 : z_1 : \dots : z_n] with not all z_i = 0, and it decomposes into affine charts U_i = \{ [z_0 : \dots : z_n] \mid z_i \neq 0 \}, each isomorphic to \mathbb{C}^n via normalization z_i = 1. The topology features a CW-cell structure with one cell in each even dimension up to $2n, rendering \mathbb{CP}^n simply connected for n \geq 1. Its cohomology ring is \mathbb{Z} / (x^{n+1}), where x generates H^2(\mathbb{CP}^n, \mathbb{Z}) \cong \mathbb{Z}, with Chern classes reflecting the tautological line bundle. In , \mathbb{CP}^n serves as the projective closure of \mathbb{C}^n and hosts embeddings of algebraic varieties; for instance, \mathbb{CP}^1 \cong S^2 , while higher \mathbb{CP}^n embed in via Veronese maps. Low-dimensional cases include \mathbb{CP}^1, the , and \mathbb{CP}^2, whose real dimension 4 distinguishes it from simply connected 4-manifolds like S^4. These spaces underpin , with the degree of hypersurfaces computed via the generator x. Less commonly, CP may abbreviate critical point in optimization or dynamical systems, denoting stationary points where gradients vanish, as in Morse theory on manifolds. In number theory, \mathbb{C}_p denotes the p-adic complex numbers, the completion of the algebraic closure of the p-adic rationals \mathbb{Q}_p, but this is subscripted and not standardly CP.

Physics

CP symmetry denotes the invariance of the laws of physics under the simultaneous application of charge conjugation (C) and parity transformation (P). Charge conjugation replaces a particle with its antiparticle, exchanging properties such as electric charge while preserving others like mass and spin. Parity inversion mirrors spatial coordinates through the origin, effectively left-right reversing the system. The CP operation combines these, predicting that the behavior of a particle system should mirror that of its antiparticle counterpart under spatial reflection. Prior to 1964, CP symmetry was hypothesized as conserved in weak interactions after parity violation was established in experiments in 1956. This followed the theoretical proposal by and Chen-Ning Yang that might not hold universally. However, and Val Fitch's experiment at in 1964 revealed through the of long-lived neutral kaons (K_L^0), where two-pion modes occurred at a rate defying CP conservation predictions, with a branching ratio asymmetry of approximately 0.2%. This discovery, confirmed by subsequent measurements, earned Cronin and Fitch the 1980 . Within the Standard Model of particle physics, CP violation emerges from an irreducible complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix, which parametrizes quark flavor mixing in weak interactions. Predicted by Makoto Kobayashi and Toshihide Maskawa in 1973 to accommodate observed asymmetries with minimal parameters, this phase—quantified by the Jarlskog invariant J ≈ 3 × 10^{-5}—manifests in decays of kaons, B mesons, and D mesons. Direct CP violation, involving interference between decay amplitudes, was first evidenced in 1969 via K_L^0 decays, while indirect violation arises from kaon mixing. The model predicts all known CP-violating observables within experimental precision, though tensions in CKM unitarity (the "unitarity triangle") persist at the 1-2 sigma level as of 2025. CP violation plays a pivotal role in cosmology, fulfilling one of Andrei Sakharov's 1967 conditions for : the generation of the observed matter-antimatter asymmetry, parameterized by the baryon-to-photon ratio η ≈ 6.1 × 10^{-10}. Without , Big Bang nucleosynthesis would produce equal matter and antimatter, leading to annihilation and a universe devoid of baryonic structure. CP sources, however, yield insufficient asymmetry by orders of magnitude, prompting searches for enhanced effects via new physics, such as or . Experimental efforts at facilities like the LHC continue to probe this, with the LHCb collaboration reporting the first observation of in baryon decays in 2025, measuring asymmetries up to 20% in charmed baryon modes, consistent with expectations but constraining beyond-Standard-Model contributions. The strong CP problem highlights an unresolved tension: (QCD) permits through a theta term in the , yet experimental bounds on the imply θ < 10^{-10}, unnaturally small without . This motivates solutions like the Peccei-Quinn mechanism, predicting axions as candidates. Ongoing precision tests, including neutrino sector searches for leptonic via the Dirac phase δ_CP, aim to resolve these discrepancies, with no evidence exceeding predictions as of October 2025.

Other uses in science and technology

In , CP denotes , an electrochemical technique that controls the of metal surfaces by rendering the protected structure the cathode of an external or sacrificial cell, thereby shifting oxidation to an . This method supplies a to counteract anodic reactions, achieving protection potentials typically between -0.85 V and -1.2 V versus a for structures in or . Widely applied since the 1820s, with modern standards formalized by bodies like AMPP (formerly NACE ), CP is critical for safeguarding buried pipelines, ship hulls, offshore platforms, and storage tanks, reducing annual global corrosion costs estimated at 3-4% of GDP in industrialized nations. In civil and , CP abbreviates , a precast or cast-in-place cylindrical conduit made from , used extensively for , sanitary sewers, and culverts due to its durability under compressive loads up to 12,000 and resistance to . Standards such as ASTM C76 specify classes based on design loads, with diameters ranging from 12 to 144 inches and service lives exceeding 100 years in non-aggressive soils. In engineering standards and construction documentation, CP refers to code of practice, a set of recommended guidelines for design, execution, and maintenance of engineering works, such as historical British Standards like CP 114 for reinforced concrete (superseded by BS codes) or CP 3 for structural wind loads, ensuring compliance with safety and performance criteria without legal enforceability.

Political Organizations

Communist Parties and Ideologies

Communist parties are political organizations dedicated to advancing , which seeks the abolition of , class distinctions, and the state through of the and a transitional . Originating in the late from socialist movements influenced by and ' The Communist Manifesto (1848), these parties gained prominence after the 1917 in , where Lenin's seized power and established the first . The formalized the model of a centralized, vanguard party of disciplined revolutionaries to guide the toward , a concept central to Leninist adaptations of . The dominant ideology of most communist parties, Marxism-Leninism, combines Marx's dialectical materialism and analysis of capitalist exploitation with Lenin's emphasis on imperialism as the highest stage of capitalism, the necessity of a professional revolutionary party, and democratic centralism for internal decision-making. Core principles include the inevitability of class struggle leading to proletarian revolution, state control of the economy to eliminate exploitation, and progression to a classless, stateless communist society. Variants emerged, such as Mao Zedong's adaptation in China, incorporating peasant-based revolution and continuous class struggle (Maoism), and Leon Trotsky's advocacy for permanent revolution and opposition to bureaucratized states (Trotskyism). In practice, these ideologies justified one-party rule, suppression of opposition, and central planning, often resulting in authoritarian governance rather than the promised withering away of the state. Historically, the Communist International (Comintern), founded in 1919 by the Russian Bolsheviks, coordinated global communist parties to export revolution, influencing formations like the Chinese Communist Party (CCP, est. 1921) and others in Europe and Asia. The Soviet Communist Party (CPSU, renamed 1918) dominated until its dissolution in 1991 amid economic collapse and the USSR's breakup. Major historical parties included the CPSU, which ruled the Soviet bloc, and the CCP, which won China's civil war in 1949. Current ruling communist parties persist in five countries: China's CCP (over 99 million members as of 2023), Vietnam's Communist Party (est. 1930), Cuba's (est. 1965), Laos' People's Revolutionary Party (est. 1955), and North Korea's Workers' Party (est. 1949), though ideological purity varies, with China and Vietnam adopting market-oriented reforms since the late 1970s and 1980s Doi Moi policy, respectively. Outside ruling contexts, parties like India's Communist Party of India (Marxist) maintain parliamentary influence but have declined since peaks in the mid-20th century. Empirical outcomes under rule reveal systemic failures in delivering prosperity or . Centralized led to inefficiencies, shortages, and stagnation, as evidenced by the Soviet economy's inability to sustain growth without reforms, culminating in per capita GDP lags behind Western comparators by the . Post-1991 transitions in showed that rapid market liberalization correlated with faster GDP recovery and higher growth rates than gradualist approaches, underscoring communism's causal role in prior economic underperformance. Human costs were immense: regimes under communist parties account for an estimated 80-100 million deaths from executions, forced labor, famines (e.g., Soviet 1932-1933, Chinese 1958-1962), and purges, per scholarly tallies of and policy-induced mortality. These figures, derived from archival data and demographic analyses, exceed those under other 20th-century ideologies, highlighting the causal link between ideological commitments to class war and coercive state power. While apologists attribute failures to external factors or deviations, first-hand regime data and comparative economics affirm inherent flaws in suppressing market signals and individual incentives.

Other political entities

The abbreviation CP denotes several political parties and organizations distinct from communist entities. In , the (CP) is a centre-right founded by Jehoash Mayanja Nkangi in the late 1970s or early 1980s, which fielded candidates in the December 1980 general elections alongside the and . The party emphasizes conservative principles including intervention and traditional social values; its leadership transitioned to Ken Lukyamuzi, who secured re-election as president in August 2012 with 106 votes during a delegate conference presided over by Nkangi. In the United States, the Constitution Party (CP), established in 1992 as the U.S. Taxpayers' Party and renamed in 1999, promotes a strict adherence to the original intent of the U.S. Constitution, advocating for the federal government's restriction to enumerated powers and the devolution of authority to states and individuals. The party's platform, as of 2025, calls for abolishing agencies like the Federal Reserve and Department of Education, prohibiting abortion, and rejecting same-sex marriage, framing these positions as restorations of biblical and constitutional foundations amid perceived federal overreach. It has achieved ballot access in multiple states and held a national committee meeting and issues conference on October 17-18, 2025, focusing on issues like fiscal restraint. The USA (CP-USA) operates as a national conservative entity prioritizing fiscal discipline, constitutional limits on federal authority, and the preservation of traditional family structures against progressive policies. Other minor or historical uses of CP include the Colorado in U.S. federal elections, which appeared on ballots under that label in the 1996 cycle per records. These entities generally align with right-leaning ideologies emphasizing , tradition, and skepticism of expansive state power, contrasting with leftist frameworks.

Legal terms

In federal law, "CP" is widely used as an abbreviation for , defined as any visual depiction, including photographs, films, videos, or computer-generated images, of sexually explicit conduct involving a minor under 18 years of age. This includes actual or simulated sexual intercourse, bestiality, masturbation, sadistic or masochistic abuse, or lascivious exhibition of the genitals or pubic area. Production, distribution, receipt, or possession of such material is criminalized under 18 U.S.C. §§ 2251–2252A, with penalties including mandatory minimum sentences of 5–15 years for first offenses involving production or distribution, escalating for repeat offenders or cases involving violence. Courts have upheld these prohibitions as outside First Amendment protection due to the harm to minors depicted, as established in (1982), which prioritized preventing child exploitation over free speech concerns. Beyond , "CP" denotes other legal concepts in specialized contexts. In and transactional , it refers to conditions precedent, which are prerequisites that must be fulfilled before a party's obligations under an become enforceable, such as regulatory approvals or completion prior to closing a merger. In securities regulation, "CP" stands for controlling , an or exercising significant over a company's operations or policies, subjecting them to potential liability for the issuer's violations under like the Securities Act of 1933. Historical court nomenclature uses "C.P." for Court of Common Pleas, a trial-level court handling civil and criminal matters in jurisdictions like and certain U.S. states prior to modern reforms. ("CP") encompasses short-term negotiable instruments like promissory notes or drafts used for financing, governed by Article 3 of the . In , "CP" may abbreviate custodial or party, designating the primary caregiver with legal custody of a in or visitation proceedings. These abbreviations vary by and context, with representing the most strictly enforced and internationally recognized prohibition, reflected in treaties like the UN Convention on the Rights of the Child and domestic implementations worldwide. Legal analyses emphasize of revictimization through distribution, where each sharing perpetuates to identifiable child victims.

Military uses

In , CP most commonly refers to a command post, defined as a unit headquarters where the and staff perform activities, equipped with essential communications, personnel, and gear to execute the mission and coordinate with higher, lower, adjacent, and supporting units. Command posts facilitate by integrating , operations planning, , and , often operating in phases such as main, tactical, or rear to adapt to conditions. For instance, U.S. Army command posts historically relied on extensive cabling but have evolved toward modular, mobile systems for rapid deployment and reduced detectability. Alternative military interpretations of CP include checkpoint, a designated site for inspecting, controlling, or securing movement of personnel, vehicles, or materials during operations to enforce security or access protocols. It also denotes collection point, a location for assembling , prisoners, supplies, or for further processing or evacuation, as in casualty collection points under U.S. Department of Defense procedures. Less frequently, CP signifies control point for regulating fires, movements, or in tactical scenarios, or contact point for initial between units. These usages appear across U.S. branches, including and manuals, emphasizing operational efficiency over standardization due to context-specific needs.

Fictional characters and concepts

In online communities, particularly among Chinese-speaking audiences, "CP" denotes "" or "couple pairing," a referring to fan-imagined or intimate relationships between two or more fictional characters from media such as novels, , dramas, or . This usage originated in virtual fiction contexts, where fans derive satisfaction from interpreting subtle interactions or creating derivative works that romanticize these pairings, often independent of canonical narratives. The term parallels "shipping" practices but emphasizes deliberate fan investment in the emotional dynamics of the pair, sometimes expressed through like "嗑CP" (kē CP), meaning to "ship" or obsess over such couples. CP as a fandom concept fosters , including fanfiction, artwork, and discussions on platforms like or , where adherents analyze character chemistry for evidence of potential romance. Studies of young adults engaging in CP behaviors highlight motivations rooted in , emotional fulfillment, and social bonding, with fans often prioritizing the pairing's perceived authenticity over real-world actor or creator intent. While predominantly applied to same-sex male pairings in (BL) genres, CP extends to heterosexual or other configurations, influencing content creation and community norms. This abstraction of characters into relational units underscores 's role in reinterpreting media for agency.

Slang, Internet Culture, and Colloquial Uses

Online and informal slang

In English-language online communities, particularly on forums, , and discussions, "CP" serves as a shorthand for "," a term used to refer to visual depictions of minors engaged in sexually explicit conduct, often as a code to circumvent content filters or algorithms. This usage has been documented in reports and investigations into online exploitation, where perpetrators employ abbreviations like "CP" to obscure searches and communications on platforms including networks and encrypted channels. For instance, analyses of trafficking patterns indicate that such terms facilitate the distribution of illegal material while evading automated detection systems. A related euphemism within these circles is "cheese pizza," which phonetically aligns with "CP" and functions as a veiled reference to the same prohibited content, emerging in culture and anonymous boards like to mock or indirectly discuss the topic. This layered slang reflects efforts to maintain amid platform crackdowns, though it has drawn scrutiny from authorities monitoring radicalized online spaces. Wait, can't cite Wiktionary. Skip or find alternative. In contrast, on Chinese social media platforms such as and , "CP" (often rendered as "嗑CP" or "kē CP," meaning "to ship CP") denotes "couple pairing," a practice analogous to "shipping" in Western and fanfiction communities, where users pair fictional characters or celebrities romantically for creative or speculative content. This sense gained traction in the early 2010s through adaptations of Korean dramas and , evolving into a staple of online discourse around media consumption. Other niche online slang includes "CP time," an informal expression rooted in (AAVE) communities, abbreviating "Colored People time" to describe chronic lateness attributed to cultural stereotypes, frequently appearing in memes and casual exchanges since at least the mid-2000s. In subcultures, such as players on and , "CP" refers to "creator points," a metric awarded for verified level designs, influencing community rankings as of platform updates around 2013. These meanings highlight the polysemous nature of abbreviations in digital vernacular, varying by linguistic and subcultural context. Urban not ideal, but for slang. Perhaps omit if no better.
