Is the Force-Velocity Profile for Free Jumping a Sound Basis for Individualized Jump Training Prescriptions?
Authors: Bobbert Maarten F. , Lindberg Kolbjørn , Paulsen Gøran 
Published: November 2024

ABSTRACT

Introduction
Formulating individualized optimized jump training prescriptions based on the force-velocity profile has become popular, but its effectiveness has been contested. Such training programs have opposite effects on ‘maximal average force’ and ‘maximal average shortening velocity’, and we set out to investigate which training-induced changes in the neuromuscular system could cause such effects.

Methods
We used a musculoskeletal simulation model with four body segments and six muscle-tendon actuators to simulate vertical squat jumps with different loads. Independent input was muscle stimulation over time, which was optimized for maximal jump height. We determined the force-velocity profile for a reference model and investigated how it changed when we modified muscle properties and initial postures.

Results
We could not reproduce the reported training effects by realistically improving muscle properties (maximal force, shortening velocity and rate of force development) or modifying initial postures of the model. However, the profile was very sensitive to gains in jump height at low-loads but not high loads, or vice versa. Reaching maximal height in force-velocity profile jumps requires skill. We argued that submaximal performance in low-load or high-load jumps caused by lack of skill could be responsible for large imbalances in profiles before training. Differential skill training promoted by the individualized optimized approach could explain quick changes toward a balanced profile.

Conclusions
If the success of individualized optimized training studies is explained by selective skill improvements, training effects are unlikely to transfer to other tasks, and individualized optimized training will not be superior to other types of training.

ABSTRACT
Changes in skeletal muscle size may be affected by resting blood flow (e.g., nutrient delivery) and this change in size is a hypothesized mechanism for changes in strength.

Purpose
To determine: 1) whether the relationship between isometric training and muscle growth depends on baseline blood flow or is mediated by a change in blood flow and 2) whether muscle growth mediates changes in maximal isometric strength.

Methods
179 participants were randomized into: low-intensity isometric handgrip exercise (LI), low-intensity isometric handgrip exercise with blood flow restriction (LI-BFR), maximal handgrip exercise (MAX), and a non-exercise control (CONTROL). Muscle thickness, strength, and resting limb blood flow were measured before and after the six-week intervention.

Results
Baseline blood flow did not moderate training effects on muscle thickness changes (MTHchg) (p = 0.666), and moderated mediation tests were non-significant. Although the LI-BFR group showed a significant effect on MTHchg (p = 0.018), MTHchg was not significantly related to handgrip strength change (HGchg) (p = 0.281), suggesting no mediation of the training-to-strength effect by MTHchg. Both the LI-BFR (p = 0.004) and MAX (p < 0.001) groups exhibited positive direct effects on HGchg compared to CONTROL. Furthermore, there were no differences between training groups and CONTROL on blood flow change (BFchg), BFchg and MTHchg were not significantly related, and neither BFchg nor MTHchg predicted HGchg, providing no evidence for mediated pathways.

Conclusions
Muscle growth may not have occurred to an extent that would require vascular adaptation. Training maximally induced the greatest strength adaptations but was seemingly not driven by muscle growth.

LAZER NAS BRECHAS DA ESCOLA
Authors: Do Rocio Vieira dos Santos Karine , Rechia Simone Aparecida 
Published: November 2024

Esse artigo tem como objetivo discutir o lazer vivenciado nas brechas dos tempos e espaços escolares. Essa face, por vezes oculta, velada e proibida, é pulsante nas vivências cotidianas formais e informais nas escolas. Metodologicamente seguimos os ritos da sociopoética, na qual é a partir da provocação de sensações e emoções que os dados são produzidos. Participaram da pesquisa crianças de turmas de 5.º ano do Ensino Fundamental. Ao fim, percebemos que o lugar do lazer na escola está na “clandestinidade”. Possível a quem se mantém atento às oportunidades e delas se aproveita, mostrando que, na escola, o lazer pode estar sendo vivenciado nas brechas dos tempos e espaços formais a partir das táticas criadas pelos estudantes.

Published: November 2024

O presente artigo tem como objetivo realizar uma revisão histórica sobre a Educação Física na Política de Ensino Médio no Brasil, com o intuito de captar sua presença no nosso território, buscando traçar uma linha do tempo, abrangendo contextos, fatos e políticas educacionais formuladas no Brasil Império, na República, até os dias atuais e, ainda, sobre seus desafios contemporâneos no contexto escolar da Reforma do Ensino Médio (Lei nº 13.415/17). A pesquisa é de cunho documental e possibilitou a reflexão sobre as políticas destinadas à educação física no Ensino Médio/Secundário contidas nas Constituições, Leis e Decretos republicanos, nas quais, identificamos as influências determinantes para sua constituição nos contexto escolar, desde a ideia de mera ‘atividade’ até sua valorização como componente curricular e, contraditoriamente, sua denominação de ‘estudos e práticas’ na Lei 13.415/17. Acreditamos que esta breve narrativa histórica sobre a Educação Física no Ensino Médio pode proporcionar uma reflexão crítica da trajetória nas políticas educacionais do Ensino Médio, entendendo fundamentalmente, a importância dessas políticas públicas para garantia dos direitos educacionais dos estudantes brasileiros.

Temporal periodic solutions of non-isentropic compressible Euler equations with geometric effects
Authors: Fang Xixi , Ma Shuyue , Yu Huimin 
Published: November 2024

Abstract
In this article, we investigate the general qusi-one-dimensional nozzle flows governed by non-isentropic compressible Euler system. First, the steady states of the subsonic and supersonic flows are analyzed. Then, the existence, stability, and uniqueness of the subsonic temporal periodic solutions around the steady states are proved by constructing a new iterative format technically. Besides, further regularity and stability of the obtained temporal periodic solutions are obtained, too. The main difficulty in the proof is coming from derivative loss, which is caused by the diagonalization. Observing that the entropy is conserved along the second characteristic curve, we overcome this difficulty by transforming the derivative of entropy with respect to

x

x

into a derivative along the direction of first or third characteristic. The results demonstrate that dissipative boundary feedback control can stabilize the non-isentropic compressible Euler equations in qusi-one-dimensional nozzles.
Unpacking fluid linguistic landscape in a community coffeehouse in Hangzhou, East China: an everyday life perspective
Authors: Yu Hua , Ai Bin 
Published: November 2024

Abstract
This paper enquires into the emergence of linguistic landscapes as cycles from fluid to frozen and fluid again. It is based on the first author’s ethnographic narratives of the appearance and disappearance of linguistic landscapes in a community coffeehouse in Hangzhou, East China. By moment analysis of the entanglements in everyday life that owners and customers share, we find that the meanings of the coffeehouse space are dynamically shaped by the intersections of their life trajectories and constant communication with others in ongoing everyday life. It is argued that linguistic landscapes emerge as a continuous flux, with language users’ care for others, willingness to correspond, and improvisation of linguistic and semiotic practices affected by their life trajectories. This paper will contribute to current research on language use in everyday space and fluid linguistic landscapes.
Scientists and drivers in-the-loop, on-the-loop or out-of-the-loop? Holistic human systems integration of teleoperated vehicles
Authors: Flemisch Frank , Usai Marcel , Schrank Andreas , Oehl Michael , Plum Lena , Shi Elisabeth , Baumann Martin , Bengler Klaus 
Published: November 2024

Abstract
The article metaphorically transfers the idea of “in-the-loop”, “out-of-the-loop” and “on-the-loop” from direct control of a vehicle to the influence and control of scientists on the in- and out-of-the-loop problem, here of teleoperation of vehicles. The article is based on the findings of an interdisciplinary group of experts coordinated by the German Federal Highway Research Institute (BASt) on the research needs for teleoperation of vehicles, in particular of Cluster 2 on the subject of Human Systems Integration. Based on three use cases of teleoperation, questions are discussed regarding the extent to which science should develop from “out-of-the-loop” towards “on-the-loop” or even “in-the-loop”, and what opportunities and risks could be associated.

A comparative analysis of the energy dissipation efficiency of various piano key weir types
Authors: Alghazali Najm O. S. , Musa Taghreed A. 
Published: November 2024

Abstract
Water levels in main or sub-channels can be controlled and regulated with the help of weirs. Piano key weirs (PKWs), a type of non-linear weir, include side crests, as well as front and back crests. Due to the fact that the PKW is a modern, newly installed infrastructure, several studies addressing the distribution of energy for each type are not yet available. This study examines the amount of energy dissipated for the four primary types, as well as the impact of altering the width ratio and the height ratio. To investigate the effects on energy dissipate, and compare the energy dissipate efficiency of the main types of PKWs, each type of PKW was created with five models using width ratios (W
i/W
o = 1.25, 1, and 0.8) and height ratios (P/L = 0.11 and 0.078). The energy dissipation depends on type of PKW and decreases as the width ratio increases by 5% and the energy dissipation increases, with the rise in the height ratio by 4%. Due to the overhang effect, type-C is the energy type that dissipates the most, making it the best example of PKW in terms of energy dissipation efficiency. Type-A follows type-C in this respect.

Published: November 2024

Abstract
This study investigated the antibacterial and photocatalytic properties of cerium oxide nanoparticles (CeO2 NPs), which were synthesized using Aegle marmelos extract. CeO2 NPs were characterized by different spectroscopy methods such as ultraviolet-visible spectroscopy, powder X-ray diffraction, and Fourier transform-infrared spectroscopy. The shape and elemental analysis of synthesized CeO2 NPs were evaluated using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy. Further, the size and stability of the synthesized CeO2 NPs were characterized by ZETA potential and dynamic light scattering analysis. Further, the photocatalytic efficiency of synthesized NPs was verified by 98% of methylene blue dye degradation exhibited within 180 min at the visible region and the first-order kinetic value was 0.2038 min−1. The green synthesized CeO2 NPs were found to have significant antibacterial activity against bacterial organisms. The effective antibacterial activity of E. coli (30 ± 0.02), P. aeruginosa (30 ± 0.07), S. aureus (24 ± 0.04), and S. epidermis (29 ± 0.04) at 100 µg·mL−1. Therefore, Aegle marmelos CeO2 NPs were used as a photocatalytic and antimicrobial therapeutic agent. The synthesized CeO2 NPs also displayed enhanced anticancer efficacy with higher concentrations against MCF-7 cells. Thus, CeO2 NPs have antibacterial, anticancer, and photocatalytic properties, according to this study.
Surveillance schafft Evidenz für die öffentliche Gesundheit
Authors: Schumacher Jakob 
Published: November 2024

Zusammenfassung
Um gezielte Maßnahmen gegen ein Public-Health-Problem zu ergreifen ist es sinnvoll, Informationen durch Surveillance zu erheben. Surveillance erfasst Ereignisse, klassifiziert diese, verarbeitet Daten, bewertet diese und kommuniziert die Erkenntnisse. Sie ist fortlaufend, definiert und zielgerichtet. Dadurch kann Evidenz geschaffen werden und der Impact von Public-Health-Maßnahmen gemessen werden. Surveillance ist unverzichtbar für die öffentliche Gesundheit und liefert Daten für Taten.

Published: November 2024

Abstract
Detailed kinetic models play a crucial role in comprehending and enhancing chemical processes. A cornerstone of these models is accurate thermodynamic and kinetic properties, ensuring fundamental insights into the processes they describe. The prediction of these thermochemical and kinetic properties presents an opportunity for machine learning, given the challenges associated with their experimental or quantum chemical determination. This study reviews recent advancements in predicting thermochemical and kinetic properties for gas-phase, liquid-phase, and catalytic processes within kinetic modeling. We assess the state-of-the-art of machine learning in property prediction, focusing on three core aspects: data, representation, and model. Moreover, emphasis is placed on machine learning techniques to efficiently utilize available data, thereby enhancing model performance. Finally, we pinpoint the lack of high-quality data as a key obstacle in applying machine learning to detailed kinetic models. Accordingly, the generation of large new datasets and further development of data-efficient machine learning techniques are identified as pivotal steps in advancing machine learning’s role in kinetic modeling.

Published: November 2024

Abstract
The description of the new version of the INM–RSHU chemistry–climate model, created on the basis of the climate model INMCM6.0 is presented. A special feature of the new version of the chemistry–climate model is the complete unification of the model structure with the basic core of the INMCM6.0 climate model. The transport of chemically active species in the atmosphere is performed on the same grid and by the same methods as the transport of meteorological parameters and aerosol. Chemical transformations are added as local processes at each grid point of the model, correcting the changes in tropospheric and stratospheric concentrations of chemically active species caused by dynamical processes. The model was tested using the results of calculations of changes in the chemical composition of the atmosphere over the last 20 years of the 20th century, performed with a version of the model with a resolution of 4 × 5 degrees in latitude and longitude.
Philosophy as Passion for Knowledge: What Kind of History of Philosophy for the 21st Century?
Authors: Ebbersmeyer Sabrina 
Published: November 2024

Abstract
This article is a slighty adapted version of my inaugural lecture as Professor of Philosophy presented on 21 June 2024 at the University of Copenhagen. Given my seniority and as the first woman ever to be appointed professor of philosophy at the University of Copenhagen, I decided to take this opportunity to address a broader and more fundamental topic: namely, what is philosophy, what role does philosophy play in today’s university systems, and what kind of history of philosophy do we need for the 21st century. My lecture has three parts. First, I present and defend a specific understanding of philosophy focussing on the notion of knowledge for its own sake. Second, I outline some of the challenges for contemporary and future historiography of philosophy. Third, I conclude with some remarks on the societal relevance of feminist history of philosophy.
Quellen des Nahöstlichen Antisemitismus
Authors: Müller Herbert Landolin 
Published: November 2024

Kurzfassung
Der Massenmord vom 7. Oktober 2023, die militärischen Reaktionen Israels sowie das weltweite Echo auf beide Vorgänge haben Manifestationen der Judenfeindschaft gezeitigt. Damit stellt sich zum wiederholten Mal das Problem antijüdischer und antisemitischer Tendenzen innerhalb migrantischer Gemeinschaften, die aus islamischen Ländern stammen. Die Interpretationen unterschiedlicher politischer Lager wie sich teils stark widersprechende akademische Deutungen zur Entstehung eines manifesten Antisemitismus zwischen dem Maghreb und Malaysia sind für interessierte Laien teilweise schwer nachvollziehbar. Hier soll ein Versuch unternommen werden, antijüdische Tendenzen innerhalb islamischer Machtbereiche der Vormoderne sowie deren Einbeziehung in antisemitische Narrative europäischen Ursprungs in der jüngeren Geschichte nachzuzeichnen.
