Future Wars and Their Morale in Post- And Transhumanist Discourse

The article serves as a continuation of the first part of reflections on future wars and the morale of their participants. The results of a survey will be presented, addressing the most important issues and controversies related to the concept of post-humanism. The study of the awareness of declared transhumanists regarding international security confirmed the heterogeneity of predictions and perceptions of globalization trends. However, even the analysis of the "metrics," i.e., the characteristics of the research group's parameters, allowed for drawing interesting conclusions. The research goal remained complex. Firstly, I wanted to confront the theoretical assumptions of post- and transhumanism; secondly, I aimed to attempt an answer to the question: Who is and what does the contemporary post- and transhumanist think about future wars?

Model parameter identification for lithium-ion batteries using adaptive multi-context cooperatively co-evolutionary parallel differential evolution algorithm

Lithium-ion battery (LIB) has a polarization phenomenon during charging and discharging processes, and the internal chemistry of LIB is characterized by severe time-varying nonlinearity. Therefore, the equivalent circuit model (ECM) is usually used for LIB research. To address the problems of low identification accuracy and local optimization in the offline identification of battery parameters, this paper proposes a novel adaptive multi-context cooperatively co-evolutionary parallel differential evolution (AMCC-PDE) algorithm to identify parameters of LIB. Firstly, the data segment to be identified is divided into a plurality of segments according to the state of charge (SOC), and each segment is called a unit data segment (UDS). In addition, the UDS has a parameter group (PG) for the first-order RC model. Secondly, according to the differential equation of the first-order RC model, the PG (R0+,R0−, D1, R1, U1, init) of each UDS and the open-circuit voltage (UOCV) at each sampling point are considered as variables to be optimized. Then, such an optimization problem is transformed into a large-scale global optimization (LSGO) problem. In addition, to trade off the relationship between population diversity and convergence speed, a novel parallel mutation strategy is proposed. Finally, an AMCC-PDE algorithm is proposed to solve the above LSGO parameters identification model. In both of the DST and FUDS datasets, the identification error at each point obtained by AMCC-PDE is lower than 2 mV, which shows the effectiveness of AMCC-PDE and indicates that the algorithm can avoid destroying the variable-coupling relationship.

The patellofemoral kinematics in patients with untreated developmental dislocation of the hip suffering from patellofemoral pain

This study reviews the dynamic patellofemoral CT results of 39 patients with untreated developmental dislocation of the hip who are suffering from knee pain. The mean age of the patients with unilateral developmental dislocation of the hip was 33.3 (±7.9), for bilateral patients 36.2 (±11.3), and for the control group, it was 31.5 (±8.5). While 14 of them were bilateral, 25 were unilateral. The CT results of 24 asymptomatic adult knees served as the control group. The patellofemoral parameters of patients with unilateral and bilateral developmental dislocation of the hip, the control group's parameters and the effect of femoral anteversion, limb length discrepancy, severity of dislocation, the mechanical axis deviation on patellofemoral parameters were analyzed. In patients with unilateral untreated developmental dislocation of the hip, although the patella was located more laterally at initial flexion degrees, it was located more medially at 30° and 60° flexion with respect to the control group. For the involved extremity, the PTA angles at 15°, 30°, and 60° flexion were significantly higher than in the control group corresponding to medial patellar tilt. In patients with bilateral developmental dislocation of the hip, the course of the patella during tracking in terms of patellar shift was similar to that of the unilateral patients. The amount of leg length discrepancy and the severity of dislocation, as well as the mechanical axis deviation, did not affect the patellofemoral parameters. The patients with untreated developmental dislocation of the hip and suffering from knee pain should be analyzed not only for tibiofemoral abnormalities but also for patellofemoral malalignment. Case-control study, Level III.

Contextual interference: varying program and parameter in the acquisition of the motor skill volleyball serve

A prática variada randômica (alta interferência contextual) tem sido considerada um fator facilitador na aquisição de habilidades motoras. Contudo, duas questões merecem especial atenção: a) qual o efeito do que é manipulado (programa ou parâmetro) durante a prática variada?; b) em que medida o efeito da interferência contextual é replicado numa situação real de ensino-aprendizagem? O presente estudo investigou essas duas questões testando o efeito da interferência contextual na aquisição de habilidades motoras complexas (saque do voleibol), onde as variações da tarefa são definidas de acordo com o programa (diferentes tipos de saque), e parâmetros (direção do saque). Quatro grupos foram formados de acordo com o aspecto manipulado e o tipo de prática variada: programa motor por blocos (PMB), programa motor randômico (PMR), parâmetro por blocos (PAB) e parâmetro randômico (PAR). Todos os sujeitos realizaram 360 execuções durante oito sessões de prática, seguidas de dois testes de transferência, um que requeria um novo programa (TT 1) e outro um novo parâmetro (TT 2), e na sessão subsequente o teste de retenção. Houve diferença inter-grupos somente na 2a. sessão da fase de aquisição, com o grupo PAR apresentando desempenho superior aos demais. No TT 1, o grupo PAR teve uma queda significante no seu desempenho em relação à 8a. sessão, e no teste de retenção todos os grupos apresentaram desempenho significativamente superior em relação à 8a. sessão de prática. O efeito da interferência contextual não foi observado no presente estudo. Isso pode ter acontecido em virtude de problemas organizacionais na condução do estudo no campo. Entretanto, não se pode descartar uma provável inconsistência interna de teoria cuja manifestação é mais marcante numa situação real de ensino-aprendizagem

The uncertainty relation for an assembly of Planck-type oscillators. A possible GR-quantum mechanics connection

It is shown that an assembly of Planck-type oscillators may be described by a continuous group with three parameters. In such a case, the uncertainty relation may be obtained by the application of a theorem on the invariant functions, when a simultaneous action of two isomorphic groups is involved. The group's parameters are interpreted by means of a variational principle, as field amplitudes of a stationary metric, while the group's invariant function is interpreted as the square root of a wave function satisfying a Schrödinger-type equation.
