Ancilla-Free Parity Network Synthesis is NP-complete

A parity network is a CNOT circuit in which every parity from a prescribed set S appears on some wire; such
networks are the CNOT skeletons of phase-polynomial circuits. Amy, Azimzadeh and Mosca (Quantum Science and
Technology, 2018) left open the ancilla-free problem with arbitrary output. We prove that deciding whether S admits
such a network with at most K CNOTs is NP-complete, even if every CNOT must produce a new parity, all parities
share a variable and have weight at most five, and connectivity is a star. Hence CNOT minimization of phase
polynomials is NP-hard even with a free linear part. The reduction is from Hamiltonian cycle in grid graphs:
networks meeting the trivial lower bound are path covers with at most one path per wire, and chaining many copies
of the instance makes a missing Hamiltonian path cost more paths than there are wires. We also show that
unrestricted networks can be shorter than fixed-target ones by a factor linear in the number of qubits.

El Método TAM-C fue concebido como una propuesta metodológica de vanguardia estructurada en tres niveles analíticos de complejidad creciente (Tipológico, Acotativo, Microscópico) y una fase Comprobacional. Esta metodología aplica procedimientos de medición matemática estricta a lo largo de sus tres niveles (acotando en centímetros, milímetros y micras) sobre impresiones dactilares, quiroscópicas y pelmatoscópicas, integrando preceptivamente la “Verificación ciega”. Este enfoque sistémico habilita una discriminación forense rigurosa (huellas humanas vs. reproducciones artificiales) mediante la caracterización micrométrica del relieve lofoscópico.
El TAM-C (Metodología) se integra de forma estructural y complementaria al ACE-V (Método). Mientras que el ACE-V rige el conjunto de procedimientos, técnicas y pasos lógicos concretos utilizados para alcanzar un objetivo en los dictámenes periciales (el cómo del razonamiento forense), el TAM-C aporta la armadura técnica y metrológica detallada para ejecutar dicha labor (el porqué y con qué herramientas), mitigando activamente los sesgos cognitivos a través de protocolos estandarizados y replicables. Frente a la disparidad doctrinal internacional que en el Nivel II (Acotativo) exige cantidades mínimas arbitrarias de minucias según la jurisprudencia de cada país, el Método TAM-C proporciona una herramienta transversal de homogeneidad: la Densidad lofoscópica. Este cálculo estandariza el análisis global transformando el simple conteo visual y subjetivo de puntos característicos en una métrica cuantitativa de concentración biométrica por unidad de área (cm²), dotando al dictamen de un peso probatorio estadístico universal y reproducible.
En el Nivel III (Microscópico), el método operacionaliza fórmulas poroscópicas (basadas en cuadrantes/subcuadrantes y numerador/exponente) y la evaluación integral mediante alboscopía forense, aplicando fórmulas alboscópicas que identifican geometrías bajo una taxonomía estandarizada (ej. líneas continuas, líneas simples, ojales e islas). Para ello, exige el empleo de software especializado destinado a la acotación micrométrica (μm) y a la vectorización geométrica, transformando el juicio visual en un parámetro estadístico objetivo y verificable. En estricto apego a los estándares científicos contemporáneos, este rigor metrológico transversal permite abandonar los modelos dogmáticos de “certeza absoluta del 100%” para culminar, de manera transparente y ética, en una conclusión pericial de “Identificación Propuesta”.

Este relatório integra dados do sistema oceânico-atmosférico (índice ONI do NOAA/CPC), da vigilância climática municipal e da vigilância epidemiológica (InfoDengue, SINAN) para caracterizar o cenário de risco à saúde pública no município do Rio de Janeiro no ciclo 2026/27 e propor um painel de indicadores operacional para a Secretaria Municipal de Saúde (SMS-Rio).
Três achados estruturam a análise. Primeiro, o El Niño de 2026 já está em curso e é forte: o ONI trimestral atingiu $+2{,}16$ °C no trimestre JAS/2026, o maior valor desde o pico de 2015/16, com intensificação de $+0{,}36$ °C em um único trimestre — precedente direto das maiores epidemias de dengue registradas no Brasil. Segundo, o gatilho hídrico local já foi acionado, mas o gatilho térmico ainda não: a chuva acumulada de julho a setembro de 2026 no município foi de 238 mm, $+56\%$ acima da climatologia 2010–2025 ($z=+1{,}93$), enquanto a temperatura máxima permaneceu abaixo do normal ($z=-0{,}36$). Terceiro, a temporada de dengue 2025/26 encerra com 17.701 casos — queda de $79\%$ e $44\%$ em relação às duas temporadas anteriores — o que reconstitui a bolsa de suscetíveis justamente quando a forçante climática se torna mais favorável.
A combinação "El Niño forte + pré-temporada úmida + bolsa de suscetíveis reposta" configura o cenário que antecedeu a epidemia de 2024 (148.431 casos). O relatório quantifica esse risco, mapeia as cadeias causais para arboviroses, leptospirose, doenças diarreicas agudas, agravos respiratórios e mortalidade por calor, identifica territórios e grupos vulneráveis, e propõe um painel de 24 indicadores com limiares de alerta em três níveis, um protocolo de acionamento e um roteiro de implantação de 120 dias para a SMS-Rio.

Sinxron tarjima – tinglash, tahlil qilish, xotirada saqlash va nutq ishlab chiqarish jarayonlarining bir vaqtning o‘zida, uzluksiz tarzda amalga oshirilishini talab qiluvchi murakkab kognitiv faoliyat turidir. D. Jaylning “Sa’y-harakat modellari” (Effort Models) nazariyasiga ko‘ra, tarjimonning kognitiv resurslari cheklangan bo‘lib, ular tinglash-tahlil (Listening and Analysis Effort), xotira (Memory Effort), nutq ishlab chiqarish (Production Effort) va muvofiqlashtirish (Coordination Effort) kabi bir necha “sa’y-harakat” o‘rtasida taqsimlanadi. Ushbu resurslar muvozanati buzilganda – masalan, manba matn juda tez yoki terminologik jihatdan murakkab bo‘lganda – tarjima sifati keskin pasayadi. Bu holat ilmiy adabiyotda “Tight-rope Hypothesis” (arqonda yurish gipotezasi) nomi bilan ham yuritiladi: tarjimon doimiy ravishda o‘zining kognitiv imkoniyat chegarasiga yaqin holatda ishlaydi va bu chegaradan ozgina chetga chiqish butun tizimning “muvozanatdan chiqishi”ga olib kelishi mumkin.

This record documents that the educational and science outreach contest "Mi superpoder preferido es…" ("My favorite superpower is…") was submitted by Constanza Ruiz-Danegger to the Innovar 2019 national innovation contest (Argentina) under project number 2019-2771, and that it appears under that number in the official Innovar 2019 catalog [section: exact name], listed with the contact location Salta.
The contest was originally conceived, designed and run in 2018 during Brain Awareness Week; its original design and rules are deposited in [DOI of the 2018 record]. It was also presented as a poster at INSAR 2019 (Montréal) [DOI of the poster record].
Derivative or replicated versions of the contest appeared in 2020 and later. They introduced substantial changes to the original design, including changes with educational implications [briefly state which rules changed, once you have written them in the rules document]. This record exists so that the original 2018 design and its 2019 submission can be cited with a fixed date, independently of those later versions.
The Innovar 2019 catalog is not authored by the depositor and is not included in this record; it is cited by reference.
