Authors: Tedesco Ana Paula , Dias Luciano , Nicolini-Panisson Renata D'Agostini 
Published: December 2023

Resumo
Objetivo: Realizar a tradução e adaptação cultural da Classificação Funcional da Mielomeningocele (MMFC) para o português (Brasil) e estudar suas propriedades psicométricas.
Método: Estudo de validação com tradução, adaptação cultural e avaliação das propriedades psicométricas: confiabilidade, teste-reteste e validade convergente. Amostra de 20 indivíduos com mielomeningocele e idade mediana de 10 (5 a 24,25) anos, com mínimo de 3 e máximo de 66 anos. A confiabilidade foi determinada pela concordância intra e interobservador, utilizando os resultados do coeficiente de correlação intraclasse (ICC) e o intervalo de confiança de 95% (IC - 95%). A validade convergente foi realizada por meio das classificações de Sharrard, Hoffer, Inventário de Avaliação Pediátrica de Incapacidade (Pediatric Evaluation of Disability Inventory [PEDI]) e Escala de Mobilidade Funcional (Functional Mobility Scale [FMS]). Além disso, o teste de correlação de Spearman foi realizado.
Resultados: A confiabilidade intraobservador (ICC: 0,900-1,0) e interobservador (ICC: 0,936; IC - 95%: 0,839-0,975) apresentou excelentes níveis de ICC. A validade convergente mostrou correlações muito fortes com FMS-5 (r = 0,94, p = 0,00) e FMS-50 (r = 0,94, p = 0,00); correlações fortes com FMS-500 (r = 0,87, p = 0,00), Sharrard (r = 0,76, p = 0,00), Hoffer (r = 0,83, p = 0,00) e Habilidades Funcionais: Mobilidade (PEDI) (r = 0,84, p = 0,00) e Assistência do Cuidador: Mobilidade (PEDI) (r = 0,77, p = 0,00); e fracas com o domínio autocuidado de PEDI (r = 0,46, p = 0,04). O teste-reteste revelou que ICC = 1,00.
Conclusões: Este estudo apresenta as propriedades psicométricas da MMFC, além de sua tradução e adaptação cultural para o português, língua nativa do autor da classificação. A MMFC demonstra correlação com classificações de mielomeningocele anteriormente utilizada. A MMFC teve bons resultados nas propriedades psicométricas avaliadas. Assim, a MMFC parece adequada e aplicável a indivíduos com mielomeningocele e é válida para a população brasileira.

Authors: Morais Sebastião Vieira de , Araújo Anderson Matheus Medeiros de , Sousa Camila Costa Lacerda de 
Published: December 2023

Resumo
Objetivo O objetivo deste estudo é identificar os fatores de risco para o aumento de sangramento perioperatório em cirurgias para tratamento de escoliose.
Métodos Estudo de coorte prospectivo incluindo 30 pacientes com escoliose idiopática submetidos à instrumentação posterior com o uso do sistema de parafusos pediculares em um hospital universitário.
Resultados As perdas sanguíneas intraoperatórias totalizaram 798,6 ml ± 340 ml (24,8% do volume sanguíneo). Houve perda maciça de sangue em 9 pacientes. Em média, a hemoglobina caiu 3,7 g/dl e foram transfundidas 1,4 bolsas de sangue por paciente. A perda sanguínea pós-operatória foi de 693,4 ml ± 331,1ml, e o total de dias utilizando dreno foi 2,7 ± 0,7. No intraoperatório, as seguintes variáveis apresentaram correlações significativas (p < 0,05) com o aumento do sangramento: idade, intervalo entre diagnóstico e tratamento, Cobb pré-operatório, quantidade de correção da curva, número de níveis instrumentados e fixados, número total de parafusos e o número de bolsas transfundidas. No pós-operatório, as seguintes variáveis apresentaram relação (p < 0,05): idade, Cobb pré-operatório, tempo de internação, quantidade de bolsas de sangue transfundidas e o número de níveis fixados com parafuso.
Conclusão As variáveis que mais contribuíram para a perda sanguínea foram idade, Cobb pré-operatório, quantidade de bolsas de sangue transfundidas e número de níveis fixados com parafuso. Portanto, os pacientes podem se beneficiar do tratamento cirúrgico enquanto mais jovens e com menor ângulo de Cobb, consequentemente, exigindo menor grau correção da curva e a utilização de implantes de menor densidade.
Cirurgia toracoscópica na abordagem da escoliose idiopática: Revisão sistemática de literatura
Authors: Aziz Rodrigo Ibrahim , Blattes Juliano Boemo 
Published: December 2023

ResumoA escoliose idiopática é caracterizada por um quadro de deformidade tridimensional da coluna vertebral com rotação axial e inclinação lateral com angulação maior que 10° segundo o Método de Cobb. Sua abordagem pode se dar de maneira conservadora ou cirúrgica, a depender do grau de angulação, desenvolvimento osteomuscular e idade da criança ou adolescente acometido, ou ainda, a depender do comprometimento funcional advindo da condição. O objetivo deste estudo foi analisar o impacto da videotoracoscopia na abordagem da escoliose idiopática. Trata-se de uma revisão sistemática de literatura, construída conforme protocolo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) e registrada no PROSPERO sob número CRD42022351466. A busca por estudos foi realizada entre agosto de 2022 e setembro do mesmo ano, em bancos de dados bibliográficos incluindo MEDLINE, The Cochrane Library e Web of Science. A técnica é uma alternativa minimamente invasiva à toracotomia que apresentou grande evolução nos últimos anos. Destacam-se como principais vantagens a menor perda sanguínea durante procedimento, menor tempo de internação e melhora da estética pós-cirúrgica. Uma das desvantagens citadas pelos autores é a maior complexidade e exigência tecnológica, maior tempo cirúrgico e necessidade de seleção criteriosa dos pacientes, conforme graus de desvio vertebral. O uso de analgésicos e anti-inflamatórios não teve diferença significativa entre os procedimentos tradicionais (toracotomia) ou videotoracoscopia.

Resumo
Objetivo Descrever e avaliar a acurácia da técnica do bloqueio PENG realizado sem auxílio de ultrassonografia.
Método Série de 40 infiltrações em pacientes com dor no quadril, em acompanhamento ambulatorial no grupo de cirurgia do quadril ou admitidos no pronto atendimento de um hospital na cidade de São Paulo. Utilizada a técnica de bloqueio nervoso pericapsular do quadril (PENG) guiado por estruturas anatômicas palpáveis da pelve e sem auxílio de ultrassonografia no posicionamento da agulha, usando o aparelho apenas para conferência da localização correta após punção não guiada.
Resultados Nos 40 quadris infiltrados em 35 pacientes com idade média de 59,2 anos, obtivemos um índice de acerto de 85%. Dos casos mal posicionados 71,4% ocorreram nas primeiras 13 aplicações e 28,6% nas 27 aplicações subsequentes. Em todos os pacientes o feixe neurovascular estava situado no terço medial da marcação realizada à caneta e mesmo nos casos em que houve falha da localização da agulha havia distância segura ao feixe neurovascular. Obtivemos apenas 1 caso de efeito adverso, onde ocorreu apraxia do nervo femoral com melhora espontânea em 2 dias.
Conclusão O bloqueio PENG não guiado é uma técnica viável e pode ser realizada por um médico que já possui conhecimento na aplicação, em serviços onde não haja disponibilidade do aparelho de ultrassonografia.
Umwelt as the foundation of an ethics of smart environments
Authors: Lecomte Patrick 
Published: December 2023

AbstractDue to the increasing embeddedness of pervasive and immersive technologies in the built environment, a new type of spaces known as smart environments emerges. With them arise many ethical issues related to freedom, agency, consciousness, and the governance of human-machine interactions. In this paper, I use Jakob von Uexküll’s Umwelt theory to devise principles for an applied ethics of umwelt, as part of a broader ethics of smart environments. Umwelt ethics is one of human beings’ surrounding world in the context of environmental capitalism. As umwelt becomes a resource to be exploited by economic agents with de facto or de jure rights to control space, defining ethical principles pertaining to the digitalization of space in the built environment is more important than ever.
From “Within” to “Beyond” in interpreting studies
Authors: Gu Chonglong , Wang Binhua 
Published: December 2023

Abstract
While there have been recent calls for an “outward turn” in (written) translation studies, interpreting
researchers have mostly taken an inward-looking view of interpreting and investigated it as a semi-closed system and an arguably
self-interested practice from within, despite the fact that interpreting in various forms and settings has been a co-constructing
factor in the transfer of knowledge and also a vital shaper of history, (geo)politics, culture, religion, communication, and our
human civilization. Going from “within” to “beyond,” this article conceptualizes interpreting as a consequential socio-political
and historical shaping force and a source of inter/trans-disciplinary conviviality and argues for an outward turn in interpreting
studies (IS). This article reviews pertinent recent studies with interdisciplinary and outward-looking features that have
endeavored to answer the important “so-what” question in IS. These studies highlight the vital role and far-reaching impact of
interpreting and interpreters in shaping different spheres of human communication and civilization across time and space. The
article also points out directions to move IS forward from a predominantly inward-looking practice. We argue that it is high time
we ventured out of our comfort zone, got off the well-trodden path, and took an outward-looking view of interpreting so that the
sub-discipline can have more meaningful and mutually enriching dialogues with other disciplines and subject areas.
On the dynamic interplay of macro and micro contexts in translation
Authors: Qiao Peng 
Published: December 2023

Abstract
This study explores the dynamic interplay between macro and micro contexts in Chinese fans’ translations of Cardi
B-related videos on Bilibili. Referring to the concept of translation as a cluster concept, Cardi B is considered as a dynamic
source cluster for interlingual and intersemiotic translations, leading to the evolving formulation of the micro context
surrounding the subtitled bullet-screen videos. Given the frequent changes in the micro context, two relatively stable components
of the macro context are initially identified for the navigation of the corresponding micro contextual elements. The macro context
includes the socio-political component of tensions in the China-United States relationship during the COVID-19 period of Trump’s
presidency, and the subcultural component of Bilibili as a carnival. By analysing the interaction between macro and micro contexts
within the target culture, as exemplified in the translator’s additions and target audiences’ on-screen danmu
comments, this study concludes that the macro and micro contexts are in dynamic interplay when the source cluster and the
translation workflow have an evolving nature. Moreover, the two contexts are no longer set at opposing ends of a spectrum.
Instead, an intermediate zone is bridged by danmu comments, blurring the boundaries between macro and micro
contexts in cyberspace.
Geodetic precession and shadow of quantum extended black holes
Authors: Saadati Reza , Shojai Fatimah 
Published: December 2023

Abstract
We study the circular motion of massive and massless particles in a recently proposed quantum-corrected Schwarzschild black hole in loop quantum gravity. This solution is supposed to introduce small but non-zero quantum corrections in the low curvature limit. In this paper, we confine our attention to the shadow of the black hole and the geodetic precession (GP) of a freely falling gyroscope in a circular orbit. Despite the mathematical complexity of the metric, our results are exact and show that the black hole shadow decreases slightly in this solution while the quantum corrections introduce a non-trivial term in the GP frequency of the gyroscope.
A pedagogical approach to introducing the honeycomb lattice gauge theory
Authors: Huang Fei-Jie , Zhao Yi-Fen 
Published: December 2023

Abstract
A pedagogical approach to introducing the honeycomb lattice gauge theory is presented. Lattice gauge theory, which is an important theory for understanding strongly correlated systems, is a significant topic covered in the quantum field theory course for graduate students. Typically, quantum field theory textbooks introduce lattice gauge theory using the square lattice. However, beginners often find it challenging to grasp such an abstract theory only through the example of the square lattice. In this paper, we introduce lattice gauge theory using an alternative lattice—the honeycomb lattice. By comparing the differences between honeycomb and square lattice gauge theories, we highlight the fundamental principles of lattice gauge theory. This pedagogical approach will assist students in gaining a fresh perspective on grasping lattice gauge theory.
Modelling assisted tunneling on the Bloch sphere using the Quantum Composer
Authors: Bley Jonas , Mattei Vieri , Goorney Simon , Sherson Jacob , Heusler Stefan 
Published: December 2023

Abstract
The Bloch sphere representation is a geometric model for all possible quantum states of a two-level system that can be used to describe the time dynamics of a qubit. As explicit application, we consider the time dynamics of a particle in a double-well potential. In particular, we adopt a recent method for off-resonant excitations, the so-called SUPER principle (Swing Up of the quantum emitter population) driven by periodic electromagnetic fields, to the context of quantum tunnelling. We show that the tunnelling probability can be enhanced significantly when an appropriate oscillation of the potential height is introduced. Driven by a collaborative approach we call educator-developer dialogue, an updated version of the software Quantum Composer is presented. For educational purposes, we map the two lowest energy states of the 1D-Schrödinger equation to the Bloch sphere representation, leading to a rather clear and intuitive physical picture for the pertinent time dynamics.
Research on key influencing factors and mechanisms of improved nitrogen fixation efficiency in magnetic-driven gliding arc
Authors: Zhang Yingzhe , Liu Baowang , Luo Jingyi , Nie Lanlan , Xian Yubin , Lu Xinpei 
Published: December 2023

Abstract
Gliding arc is considered to be an efficient method for nitrogen fixation. In this study, an improved magnetic-driven rotating gliding arc method was adopted to investigate the effects of gas flow rate, current, magnetic field, nitrogen-to-oxygen ratio in the working gas, and relative humidity on nitrogen fixation efficiency. To further understand the relationship between the discharge mechanism and nitrogen fixation efficiency, the arc length, arc diameter, arc rotation frequency, and reaction pathway were studied to find the relationship between external parameters, discharge characteristics, and nitrogen fixation efficiency. The research results indicate that the discharge current and magnetic field not only change the rotation frequency of the gliding arc, but also affect its length and diameter, and the amount of ionizing gases involved in the working gas, thus affecting nitrogen fixation efficiency. When the nitrogen volume ratio in the feed gas is 60%, the lowest energy cost can be achieved, which is 18.6% lower than that of air. The energy cost of nitrogen fixation is closely related to the humidity of the air. As the humidity increases, the energy cost also increases. At the magnetic field strength of 160 mT, gas flow rate of 10 l min−1, and current of 40 mA, the energy cost of 1.708 MJ mol−1 is realized which is the current lowest for plasma nitrogen fixation in this study.
A football-like acoustic metamaterial with near-zero refractive index and broadband ventilated sound insulation
Authors: Wang Yipu , Chen Wenjiong , Liu Shutian 
Published: December 2023

Abstract
Acoustic metamaterial with negative or near-zero refractive index exhibits extraordinary acoustic transmission characteristics, including acoustic total reflection, acoustic stealth and acoustic tunneling. Based on the coiled-up space structure, a football like near-zero refractive index acoustic metamaterial (FNZIM) was proposed. The result reveals the formation of two transmission peaks at 1270 Hz and 2300 Hz from the equivalent parameters by using the transfer matrix method. The first peak exhibits excellent air impedance matching, while the second peak arising from the metamaterial’s near-zero refractive index. We then constructed an acoustic prism using 15 cells of FNZIM and calculated the dispersion curve, revealing that the near-zero refractive index supernormal transmission of metamaterials is attributable to multimode degeneracy. Furthermore, we find that the positions of the transmission peaks and transmission loss can be adjusted by appropriately altering the structural parameters. Finally, we tested two groups of samples by using impedance tube four-channel to verify the accuracy of the simulation and the validity of insulation performance of FNZIM. The broadband ventilation sound insulation coupled structure is constructed, and the average sound insulation performance of this structure is more than 25 dB in the range of 1140–2210 Hz.
Modeling of a Ti/NiTi spring-blade gear for space micro–vibration isolation

Published: December 2023

Abstract
Space pointing mechanisms are crucial in space scientific experiments and observations. Since the precision of such mechanisms is highly susceptible to micro–vibrations due to environmental disturbances and inherent defects, isolating micro–vibrations is important. A low rotational stiffness spring-blade gear installed on the output shaft of the stepper motor can isolate micro–vibrations due to the motor’s discontinuous rotation. However, a quantitative performance description is still lacking. In this paper, a rotational stiffness model for the spring-blade gear made of titanium and nickel–titanium-based shape memory alloy is established and experimentally validated. A vibration transmissibility model is developed, revealing the relationships among the layout, material properties, structural parameters, external loads, rotational stiffness, and vibration transmissibility of the spring-blade gear. This paper can be used to design and optimize the spring-blade gear, predicting the isolation and suppression capability against micro–vibrations at different frequency ranges. The optimal gear structure can be obtained according to vibration isolation requirements, load, and installation constraints to achieve the predetermined vibration isolation effect. This study can ensure the space pointing mechanisms operate with high precision and stability by attenuating space micro–vibrations effectively, improving the quality of signal acquisition and observation accuracy.

Abstract
In recent years Bi2Sr2CaCu2O
x
(Bi-2212) received increasing attention due to its round wire multifilamentary architecture, a unique feature in high-Tc
superconductor. In fact, round wires are preferable for magnet designs, including solenoids for nuclear magnetic resonance (NMR) or research purpose and accelerator magnets. However, due to the narrow over-pressure heat treatment conditions necessary to obtain high Jc
and to the peculiar microstructure of Bi-2212 wires, a full understanding of the correlations between the different properties has not yet been developed. In this paper we investigate the effect of a vital part of Bi-2212 optimization, the maximum heat-treatment temperature T
max in the range of 885 °C–896 °C, on the variations of Jc
, effective filament diameter d
eff, anisotropy γ, INTER- and intra-grain irreversibility fields and pinning energies U
0, all critical parameters in unravelling the complex mix of vortex pinning and connectivity that ultimately determines the critical current density. We found that d
eff of the higher Jc
wires heat-treated at lower temperature is much smaller than for the lower Jc
wires. Moreover, a systematic increase of the irreversibility field and a decrease of the intrinsic Bi-2212 anisotropy underpins the higher Jc
. The analysis of the pinning energies reveals that there is little sample-to-sample variation in the INTER-grain pinning, whereas in all samples the intra-grain pinning has an enhancement below ∼40–45 K becoming more and more evident with increasing Jc
. These results suggest that the overall Jc
performance are not only related to the wire microstructure and connectivity, which obviously affect the INTER-grain properties, but they are also intimately related to the intrinsic and intra-grain properties such as γ and U
0.
Degenerate behaviors and decompositions of the two-soliton solution in the (1+1)-dimensional Ito equation
Authors: Wang Lirong , Wang Chuanjian , Li Changzhao , Wang Yuye 
Published: December 2023

Abstract
In this paper, we investigate the degenerate behaviors and decompositions of two-soliton solution on the non-vanishing constant background for the (1+1)-dimensional Ito equation. By tuning the background constant, interaction phenomena of various types such as the elastic interaction of solitons, fission or fusion phenomena are presented. The degenerate two-soliton solutions which lead to a higher amplitude soliton in collisions of two solitons or describe the decay of a soliton into two new solitons are obtained. To better understand the nature of these interaction phenomena, we explore different decompositions to express the two-soliton solution as a sum of two functions. One of the function exhibits a special soliton excited by the collisions of two solitons, and the other describes the energy exchange of two solitons. Finally, under the module resonance of wave numbers, other types of the degenerate solutions of two solitons are derived and analyzed, such as the breather and rogue wave solutions.
