Non-localized postactivation performance enhancement (PAPE) effect in trained athletes: a pilot study

Fifteen trained athletes were assessed for postactivation performance enhancement (PAPE) of squat jumps (SJ) and power push-ups (PPU) following upper body activation, lower body activation, upper and lower body activation, and rest. SJ improved similarly across all four conditions. PPU could not be assessed. Since the protocol of SJ and PPU involved upper and lower body activation and caused PAPE in SJ, future work is required to determine if a non-localized PAPE effect exists.CTS-527: Actividad física y deportiva en el medio acuátic

Wilson loops stability in the gauge/string correspondence

We study the stability of some classical string worldsheet solutions employed for computing the potential energy between two static fundamental quarks in confining and non-confining gravity duals. We discuss the fixing of the diffeomorphism invariance of the string action, its relation with the fluctuation orientation and the interpretation of the quark mass substraction worldsheet needed for computing the potential energy in smooth (confining) gravity background. We consider various dual gravity backgrounds and show by a numerical analysis the existence of instabilities under linear fluctuations for classical string embedding solutions having positive length function derivative $L'(r_0)>0$. Finally we make a brief discussion of 't Hooft loops in non-conformal backgrounds.Comment: 34 pages, 36 figures. Reference added. Final version JHEP accepte

The SSN ontology of the W3C semantic sensor network incubator group

The W3C Semantic Sensor Network Incubator group (the SSN-XG) produced an OWL 2 ontology to describe sensors and observations ? the SSN ontology, available at http://purl.oclc.org/NET/ssnx/ssn. The SSN ontology can describe sensors in terms of capabilities, measurement processes, observations and deployments. This article describes the SSN ontology. It further gives an example and describes the use of the ontology in recent research projects

Viscous dynamics associated with hypoexcitation and structural disintegration in neurodegeneration via generative whole-brain modeling

INTRODUCTION Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD) lack mechanistic biophysical modeling in diverse, underrepresented populations. Electroencephalography (EEG) is a high temporal resolution, cost-effective technique for studying dementia globally, but lacks mechanistic models and produces non-replicable results. METHODS We developed a generative whole-brain model that combines EEG source-level metaconnectivity, anatomical priors, and a perturbational approach. This model was applied to Global South participants (AD, bvFTD, and healthy controls). RESULTS Metaconnectivity outperformed pairwise connectivity and revealed more viscous dynamics in patients, with altered metaconnectivity patterns associated with multimodal disease presentation. The biophysical model showed that connectome disintegration and hypoexcitability triggered altered metaconnectivity dynamics and identified critical regions for brain stimulation. We replicated the main results in a second subset of participants for validation with unharmonized, heterogeneous recording settings. DISCUSSION The results provide a novel agenda for developing mechanistic model-inspired characterization and therapies in clinical, translational, and computational neuroscience settings

Entanglement Hamiltonians in 1D free lattice models after a global quantum quench

We study the temporal evolution of the entanglement Hamiltonian of an interval after a global quantum quench in free lattice models in one spatial dimension. In a harmonic chain we explore a quench of the frequency parameter. In a chain of free fermions at half filling we consider the evolution of the ground state of a fully dimerised chain through the homogeneous Hamiltonian. We focus on critical evolution Hamiltonians. The temporal evolutions of the gaps in the entanglement spectrum are analysed. The entanglement Hamiltonians in these models are characterised by matrices that provide also contours for the entanglement entropies. The temporal evolution of these contours for the entanglement entropy is studied, also by employing existing conformal field theory results for the semi-infinite line and the quasi-particle picture for the global quench

Os limites das capitanias hereditárias do sul e o conceito de território

Analisam-se os limites das capitanias do sul (1534-1700), chegando a interessantes conclusões. As terras da Capitania de Santana, em função da estimativa que se faça para a longitude de Tordesilhas, ou pertenciam à Espanha ou formavam pequenas parcelas descontínuas. O limite norte da Capitania de São Tomé (Pero de Góis), definido por acordo entre os dois confrontantes, afetava um terceiro território, coisa que não se percebeu. O limite sul dessa capitania na carta de doação indicava uma linha correndo diretamente para oeste, enquanto que na de seu vizinho (Martim Afonso) indicava uma linha correndo a noroeste. Essa mesma direção também está definida para o limite sul desse lote, complicando a partição das terras. Essas fronteiras artificiais nunca foram demarcadas nem tidas em conta, e tanto os donatários como a Coroa foram criando vilas e cidades em terreno alheio: umas vezes por não levar em conta os limites das cartas de doação (São Paulo, Santana de Parnaíba, Mogi das Cruzes, São Sebastião, Taubaté, Paranaguá, por exemplo); outras por ocupação indevida, mas necessária (Rio de Janeiro); por dolo ou extrapolação de poderes (Cabo Frio); ou mesmo em terras de Castela (Curitiba). A isso veio somar-se a questão de jurisdição sobre a Capitania de Santo Amaro (a querela entre as casas de Monsanto e Vimieiro); a questão da extrapolação de jurisdição (Angra dos Reis e Paraty); e finalmente a má-fé e as tropelias de juízes, capitães-gerais e da Coroa. O entendimento dessas questões, facilitada pela cartografia histórica, permitiu revelar pontos desconhecidos da história das capitanias, explicar melhor a formação dos limites dos atuais Estados e aprofundar-se no entendimento dos conceitos da época para indicar o território: termo, sertões, fundos e outros.We analyze the limits of the southern Captaincies (1534-1700), reaching interesting conclusions. The Terras de Santana Captaincy, depending on the estimate of the longitude of the Tordesillas line, or belonged to Spain or are formed by small discrete portions. The northern limit of the Captaincy of São Tomé (Pero de Gois) defined by agreement between the two neighbors affected a third territory, something that was not perceived. The southern boundary of this Captaincy in the Donation Letter indicated a line running directly to the west, while in his neighbor Letter (Martim Afonso) indicated a line running northwest. This same direction is also set to the southern limit of that lot, complicating the partition of the lands. These artificial boundaries have never been demarcated or taken into account, and both the donatories, as the crown, were creating towns and cities in foreign land: sometimes for not taking into account the limits of the Donation Letters (São Paulo, Santana de Parnaiba, Mogi das Cruzes, São Sebastião, Taubaté, Paranaguá, for example); others by improper occupation, even when necessary (Rio de Janeiro); intentionally or extrapolation of powers (Cabo Frio); or even in the land of Castile (Curitiba). To this has added up the question of jurisdiction over the Captaincy of Santo Amaro (the quarrel between the houses of Monsanto and Vimieiro); the question of extrapolation jurisdiction (Angra dos Reis and Paraty) and finally the bad faith and mischief of judges, general captains and the crown. The understanding of these issues, facilitated by historical cartography, allows us to understand unknown point of the history of the captaincies; a better explain of the formation of the limits of current States and a deeper the understanding of the concepts of that time to indicate the territory: termo, sertão (hinterlands), fundos (funds) and others
