Disrupción táctica basada en el caos (aprovechamiento y explotación del caos): Un nuevo enfoque de combate
Authors: Mogollón Sandoval Oscar Jorge , Pimentel Roque Víctor Manuel
Published: January 2025

Este artículo explora la teoría de la disrupción táctica basada en el caos, cuyo objetivo principal es desestabilizar al enemigo a través de maniobras rápidas, impredecibles y multidimensionales que generen incertidumbre y desorganización operativa. Para evaluar su aplicabilidad, se combinaron un análisis histórico-comparativo, un enfoque conceptual basado en teorías como el ciclo OODA y la fricción de Clausewitz, y simulaciones tácticas mediante un juego de la guerra en formato de tablero. Los resultados demuestran que la disrupción táctica maximiza las ventajas en el combate mediante la explotación del caos en contextos defensivos y ofensivos, integrando tácticas híbridas, sorpresas estratégicas y el uso de tecnologías como drones y ciberataques. Este enfoque destaca por su adaptabilidad a escenarios modernos, aunque también presenta desafíos éticos y operativos que requieren atención para su implementación exitosa

Diferenças entre a Etnomusicologia Brasileira e a Etnomusicologia "Mundial”
Authors: Souza Juliana Lima Catinin de
Published: January 2025

This article aims to discuss the main characteristics of Brazilian Ethnomusicology, drawing a parallel between it and “world” Ethnomusicology – the one monopolized by researchers born or based in Europe and, especially in the USA, due to their economic and ideological dominance. The distinction considered the material and historical reality of Brazil in order to understand some of the discipline's determinations and limitations in the country, especially with regard to academic practices. By scrutinizing the limits of Ethnomusicology as a theoretical-practical discipline, the article seeks to indicate some of the tensions that its expansion in Brazilian higher education can cause, in this way mentioning the conservative and elitist character still present in many universities. In this sense, using Carlos Sandroni's surveys of the state of the discipline in the country in 2008 as a starting point, this article suggests the need to consolidate ourselves as a critical discipline in order to discuss necessary changes in Brazilian society through praxis.
“Negrada, olha a linha”!
Authors: Santos Climério de Oliveira
Published: January 2025

The work discusses the maracatusnação songs, an Afrodiasporic cultural manifestation, especially those sung by Maracatu Leão Coroado, the oldest group in Pernambuco in uninterrupted activity, founded in 1863, based in Olinda, Metropolitan Region of Recife. The toadas, short songs, are the sung parts and are accompanied by the baque (work of the percussive ensemble) in the maracatu’s procession. Historically, the toadas received little attention from maracatu scholars and their verses were interpreted as a cultural reminiscence of the past and negatively regarded. They are addressed here as songs of resistance, re-existence and “literacies of re-existence” of the members in their fight to defend identity, against racism and for improved living conditions. The work is based on experiences and research with the Leão Coroado community and on interactions between this researcher and other maracatu groups, based on concepts and notions of ethnomusicology and human sciences. The analysis brings to light the symbolic force of the toada, the way in which through it the members re-signify maracatu, resist, acquire knowledge to re-exist and produce meanings in the present.

Long-term changes in water level of the northwestern part of the Black Sea
Authors: Vyshnevskyi Viktor , Dykhanov Yuryi , Komorin Viktor
Published: January 2025

The characteristics of sea water level (SWL) in the northwestern part of the Black Sea and the main influencing factors were studied. Based on observation data, it was found that the mean SWL at hydrological stations along the coast is similar. Over the past four decades, an increase in SWL has been observed, with an average rate of about 3.3 mm per year. This rise is comparable to the average increase observed in the World Ocean. Since about 2000, the increase in level has practically disappeared. It was shown that this feature is caused by the changes of the Black Sea water balance. The increase of air temperature in the studied region is greater than worldwide. This increase is observed alongside with the increase in water temperature and a significant increase in evaporation from the sea surface. The inflowing river runoff, which has been less than usualin recent years, also has an effect on SWL. In addition to long-term changes, seasonal fluctuations also occur. During a year, the smallest increase is observed in May and June, the largest – in November and February. The intra-annual distribution of water runoff from the Danube and Dnipro rivers is the primary factor that influences the seasonal changes of SWL.

Authors: Żaba Tadeusz
Published: January 2025

Energia elektryczna stanowi ważną pozycję w kosztach działalności każdego przedsiębiorstwa. Dlatego jej oszczędne zużycie oraz możliwość generacji dają szansę na znalezienie oszczędności i uzyskanie lepszej pozycji rynkowej. Generacja rozproszona pozwala nie tylko na ograniczenie kosztów, ale również zmniejszenie strat na przesyle oraz zwiększenie niezawodności. Wytwarzanie energii nabiera szczególnego znaczenia w przypadku przedsiębiorstw komunalnych, których koszty funkcjonowania przekładają się bezpośrednio na stawki opłat ponoszonych przez mieszkańców. Zwykle tego typu przedsiębiorstwa posiadają naturalne uwarunkowania,jak np. miejsce pod zabudowę odnawialnych źródeł energii. Rozwój OZE to nie tylko moda, ale przede wszystkim działanie w celu ograniczenia emisji i redukcji zanieczyszczeń emitowanych do atmosfery.Oszczędność opłat za energię elektryczną można uzyskać przez jej wytwarzanie, ale także dzięki zastosowaniu inteligentnych rozwiązań w zakresie optymalizacji sterowania pracą głównych odbiorników energii elektrycznej. Wykorzystanie inteligentnych narzędzi staje się coraz bardziej powszechnie, a koszty poniesione na wdrożenie zwracają się w krótkim okresie. Tego typu środki pozwalają również na ograniczenie kosztów związanych z obsługą oraz na zapewnienie bezpieczeństwa prowadzonych procesów technologicznych. W artykule przedstawiono działania w zakresie wytwarzania i oszczędzania energii na przykładzie Wodociągów Miasta Krakowa SA.

Optical fields, as a type of information carrier, travels fast and can carry a large of information in quantum information processing and transmission. Therefore, it’s concerned for the storage and retrieval of the quantum information. However, in the process of optical field propagation, its dispersion and diffraction effect cause distortion of quantum information in a certain range. Comparing with light, the optical solitons, which are from the balance between dispersion (diffraction) and nonlinearity of the system, possess higher stability and higher fidelity as the information carries, so that it has gained considerable attention in ultra-cold atomic and semiconductor quantum dots electromagnetically induced transparency (EIT) media and so on. Till now, there are few reports on the storage and retrieval of optical solitons in the semiconductor quantum wells system.
Based on this, we, in this paper, construct an N-type four-level asymmetrical GaAs/AlGaAs double quantum well EIT model with the cross-coupling relaxation of the longitudinal-optical phonons. Of course, the cross-coupling relaxation of the longitudinal-optical phonons between the conduction band levels of the GaAs/AlGaAs double quantum wells have been successfully embedded in the experiments. Subsequently, we study its linear absorption and nonlinear propagation properties by applying the semi-classical theory and the multi-scale method combined with numerical simulation. It is shown that when both control fields are turned on, there exhibits double transparent windows in the linear case. Interestingly, when the strength of the cross-coupling relaxation of the longitudinal-optical phonons increases, there occurs an approximately perfectly symmetrical double transparent window in the system.
For the nonlinear case, the optical solitons cannot propagate stably under the consideration of the third order of the multi-scale expansion,. Only after the forth order of the multi-scale expansion are considered, the optical solitons formed can propagate stably. It is worth mentioning that only higher-order optical solitons can be stored and retrieved by switching off and on the control fields. Furthermore, numerical simulation shows that the fidelity of the storage and retrieval of the optical soliton is higher than that of ordinary optical pulse. In addition, it is found that the amplitude of the stored optical soliton can be controlled by the strength of the cross-coupling relaxation of the longitudinal-optical phonons. These results are possibility to improve the fidelity for the storage and retrieval of quantum information in semiconductor quantum wells devices.

In an integrated ion trap with integrated optical modules, the problem of misalignment between the optical focus and the trapped ion saddle point is very likely to occur, which seriously hinders the practicality of the experimental method. To solve this problem, the multi-RF field method can be used to compensate for and move the ion saddle point position. However, in the actual experimental process, the application of the multi-RF method requires the knowledge of the amplitude of the RF voltage to be loaded corresponding to the actual spatial position of the saddle point. Therefore, a set of mathematical models is established to describe the relationship. The accuracy of the model determines the control accuracy of the spatial position of the saddle point, and the simplicity of the model determines the speed of the solution process. Therefore, in this work, a mathematical model of the relationship between the multi-RF electric field voltage and the saddle point position is proposed based on the numerically simulated electric field distribution and the polynomial fitting method. It can quickly and accurately give a mathematical description between the two without considering the physical mechanism or model. Numerical method is adopted to verify and discuss the correctness and scope of application of the model, and can quickly and accurately provide the amplitude of the RF voltage to be loaded in the experiment, causing the saddle point to move and coincide with the optical focus. This method greatly reduces the time delay caused by the solution and improves the feedback loop bandwidth during the movement of the saddle point position.

Published: January 2025

Host selection by mosquitoes is a keystone to understanding viral circulation and predicting future infection outbreaks.
Culex
mosquitoes frequently feed on birds during spring and early summer, shifting into mammals towards late summer and autumn. This host switch may be due to changes in mosquito fitness. The aim of this study was to assess if the interaction effect of blood meal source and seasonality may influence reproductive traits of
Culex quinquefasciatus
mosquitoes. For this purpose,
Cx. quinquefasciatus
mosquitoes were reared in simulated summer and autumn conditions and fed on two different hosts, chickens and mice, in a factorial design. Fecundity, fertility, and hatchability during two consecutive gonotrophic cycles were estimated. We found greater fecundity and fertility for mosquitoes fed upon birds than mammals. Fecundity and fertility did not vary between seasons for chicken-fed mosquitoes, whereas in autumn they decreased for mouse-fed mosquitoes. These traits decreased in the second gonotrophic cycle for mouse-fed mosquitoes, whereas they did not vary between cycles for chicken-fed mosquitoes. There was no statistically significant variation of hatchability among treatments. These results indicate a statistically significant interaction effect of blood meal source and seasonality on fecundity and fertility. However, the pattern was opposite in relation to our hypothesis, suggesting that further studies are needed to confirm and expand our knowledge about mosquito biology and its relationship with seasonal host use shifting.
SLFCNet: an ultra-lightweight and efficient strawberry feature classification network
Authors: Xu Wenchao , Wang Yangxu , Yang Jiahao
Published: January 2025

Background

As modern agricultural technology advances, the automated detection, classification, and harvesting of strawberries have become an inevitable trend. Among these tasks, the classification of strawberries stands as a pivotal juncture. Nevertheless, existing object detection methods struggle with substantial computational demands, high resource utilization, and reduced detection efficiency. These challenges make deployment on edge devices difficult and lead to suboptimal user experiences.

Methods

In this study, we have developed a lightweight model capable of real-time detection and classification of strawberry fruit, named the Strawberry Lightweight Feature Classify Network (SLFCNet). This innovative system incorporates a lightweight encoder and a self-designed feature extraction module called the Combined Convolutional Concatenation and Sequential Convolutional (C3SC). While maintaining model compactness, this architecture significantly enhances its feature decoding capabilities. To evaluate the model’s generalization potential, we utilized a high-resolution strawberry dataset collected directly from the fields. By employing image augmentation techniques, we conducted experimental comparisons between manually counted data and the model’s inference-based detection and classification results.

Results

The SLFCNet model achieves an average precision of 98.9% in the mAP@0.5 metric, with a precision rate of 94.7% and a recall rate of 93.2%. Notably, SLFCNet features a streamlined design, resulting in a compact model size of only 3.57 MB. On an economical GTX 1080 Ti GPU, the processing time per image is a mere 4.1 ms. This indicates that the model can smoothly run on edge devices, ensuring real-time performance. Thus, it emerges as a novel solution for the automation and management of strawberry harvesting, providing real-time performance and presenting a new solution for the automatic management of strawberry picking.

Background

Hepatitis B virus (HBV) is a global health issue, particularly among healthcare personnel, including students because of its occupational exposure pattern. Healthcare Workers and medical students are recommended to have better knowledge, attitudes and good practices and vaccination toward infection control in general and HBV in particular. This study aimed to assess the knowledge, attitudes, and practices of medical students from North Sudan regarding HBV and its vaccination coverage.

Methods

A cross-sectional study was conducted from January to June 2023 among medical students in North Sudan. Data were collected using a structured scale using online Google Forms. Descriptive and comparative analyses were performed using SPSS version 26. Statistical significance was set at p ≤ 0.05.

Results

A total of 426 medical students were included in the study. The majority had good knowledge about HBV (86%) and its transmission methods (77%). The majority showed a favorable attitude (77%). The practice score was however very low (15.5%). Older age and advanced academic level were significantly associated with good knowledge (aOR: 3.9; CI 95% [3.69–12.92]; p = 0.016, and aOR: 2.6; CI 95% [1.16–6.15]; p = 0.020, respectively). Only a third of the students were vaccinated (33.0%), with only a few of them received complete doses (18.6%).

Conclusion

Students from medical colleges in North Sudan had good knowledge and favorable attitudes toward HBV. However, good practice was low. Older age and advanced academic level were significantly associated with knowledge level. Vaccination coverage was also low among the students in this study.
A giant specimen of Rhamphorhynchus muensteri and comments on the ontogeny of rhamphorhynchines
Authors: Hone David W.E. , McDavid Skye N.
Published: January 2025

Rhamphorhynchus is one of the best-known pterosaurs, with well over 100 specimens being held in public collections. Most of these represent juvenile animals, and the adults known are typically around 1 m in wingspan. Here we describe a near complete skeleton, preserved partially in 3D, of an animal with a wingspan of around 1.8 m, that is considerably larger than other known specimens, and is among the largest known non-pterodactyloid pterosaurs. This animal shows differences in the anatomy not seen in smaller specimens, revealing details of late-stage ontogeny in this genus. The specimen exhibits a disproportionate reduction in the size of the orbit and increase in the size of the lower temporal fenestra, a reduction in the proportional mandibular symphysis, and unusually laterally flattened teeth, which may point to a changing diet as these animals grew. These features show a transition from smaller to larger specimens of Rhamphorhynchus and also appear in other large specimens of rhamphorhyhchines and point to a consistent pattern in their development.
The inter-trial and inter-session reliability of Theia3D-derived markerless gait analysis in tight versus loose clothing

Published: January 2025

Background

Gait analysis is traditionally conducted using marker-based methods yet markerless motion capture is emerging as an alternative. Initial studies have begun to evaluate the reliability of markerless motion capture yet the evaluation of different clothing conditions across sessions and complete evaluation of the lower limb and pelvis reliability have yet to be considered. The aim of this study was to evaluate the inter-trial, inter-session and inter-session-clothing variation and root mean square differences between tight- or loose-fitting clothing during walking.

Method

Twenty-two healthy adult participants walked along an indoor walkway whilst eight video cameras recorded their gait in either tight- or loose-fitting clothing. A commercial markerless motion capture system (Theia3D) provided gait kinematics for evaluation.

Results

Reliability results showed average inter-trial variation of <2°, inter-session variation of <3° and inter-session-clothing variation <3.5°. Root mean square differences (RMSD) between clothing conditions were <2°.

Discussion

Pelvis variations were smaller than those at the hip, knee and ankle. Our results showed smaller variation than in previous studies which may be due to updates to software. The demonstration of the reliability of markerless motion capture for gait analysis in healthy adults should prompt further evaluation in clinical conditions and reconsideration of multi-assessor marker-based gait analysis protocols, where variation is highest.
Basis of single-seed formation in chestnut: cytomorphological observations reveal ovule developmental patterns of Castanea henryi
Authors: Qiu Qi , Tian Xiaoming , Wu Guolong , Wu Juntao , Yuan Deyi , Fan Xiaoming
Published: January 2025

Background

Many plants, including those commonly found in the Fagaceae family, produce more flowers and ovules than mature fruits and seeds. In Castanea henryi, an ovary contains 16–24 ovules, but only one develops into a seed. The other ovules abort or otherwise fail to fully develop, but the reason for this is unknown. Such a strict reproductive screening mechanism is rare in plants.

Methods

In this study, controlled pollination scheme were adopted, and conventional paraffin embedding and semi-thin sectioning techniques, followed by microscopy, were used for cytological studies of ovule development in C. henryi.

Results

Pollination affected not only the process of ovule development, but also the proportion of ovules that formed mature embryo sacs. Approximately 53.53% of the ovules in the pollinated treatment developed normally, while only 16.55% of the ovules in the unpollinated treatment developed into mature embryo sacs with a seven-cell, eight-nucleated structure. Failure to form mature embryo sacs and the abnormal divisions of the zygote, respectively, were the reasons for the pre- and post-fertilization ovule failures. Our findings not only provide basic information on the reproductive biology and also information on seed production of C. henryi.
Las técnicas de reproducción humana asistida y su desvinculación del derecho a la salud y autonomía reproductivas
Authors: Melgar Rimachi Adriana
Published: January 2025

El objeto de este artículo es proveer de una justificación suficiente a la objeción de la tesis actual que postula a las técnicas de reproducción humana asistida (TERAS) como parte de los derechos reproductivos. Se discutirá que la prohibición de las TERAS supone una violación del derecho a la salud y autonomía reproductivas; que del derecho a fundar una familia se deriva el derecho a acceder libremente a las TERAS; y que los denominados “derechos” al hijo o a la reproducción asistida por motivos sociales forman parte de los derechos reproductivos. Este trabajo tratará estas cuestiones en el contexto de parejas infértiles. Se ofrece una perspectiva femenina renovada que reconoce la reivindicación de la mujer, de la maternidad y paternidad, y abre paso a un nuevo debate acerca de los derechos reproductivos en el marco del continuo repensar de los derechos humanos.
¿Es la condicionalidad compatible con un sistema de asistencia social que aspira a la universalidad?
Authors: Ponce de León Solís Viviana
Published: January 2025

Este artículo busca precisar en qué medida la vocación universal del sistema de asistencia social chileno –encarnado en el Sistema Intersectorial de Protección Social– es compatible con la imposición de condiciones que limiten el acceso y el goce de prestaciones dirigidas a proveer un mínimo social bajo el cual nadie debería caer. La hipótesis que se plantea es que la universalidad que ofrece el sistema chileno es compatible con condiciones relativas al estatus de los beneficiarios de asistencia social y con aquellas que apoyan la autonomía de estos, por oposición a aquellas que tienen un carácter punitivo. Por ende, mu- chas de las condiciones conductuales que prevé el Sistema, así como las sanciones que trae aparejada la inobservancia de las ellas, deben ser cuidadosamente evaluadas.
¿Existe la prueba ilícita, lícitamente obtenida, en el Proceso Penal chileno?
Authors: Correa Robles Carlos , Pardo-Álvarez Diego
Published: January 2025

En el derecho procesal penal alemán es admisible prohibir la valoración por el juez de un elemento probatorio con independencia de haber sido éste obtenido lícitamente. Estas son las llamadas prohibiciones de valoración de prueba independiente. La principal justificación para tales prohibiciones es constitucional: la valoración misma de un medio de prueba podría constituir una infracción a los derechos fundamentales de las personas. Este trabajo analiza las prohibiciones de valoración independientes en la doctrina y jurisprudencia alemana, con el fin de preguntarse si sus elementos constitutivos son constatables en el derecho procesal penal chileno, y si la vía de solución propuesta a nivel constitucional desde el derecho alemán representa una alternativa plausible en el derecho constitucional chileno.
Sobre la ilegalidad del consentimiento de menores de edad a las intervenciones médicas transafirmativas irreversibles
Authors: Zúñiga-Fajuri Alejandra
Published: January 2025

Las modificaciones legales introducidas por la Ley Nº 21.331 de Salud Mental, reconocen el derecho a la autonomía progresiva de niños, niñas y adolescentes (NNA) en materia de asentimiento, conservando el ejercicio del consentimiento informado en sus padres o representantes legales y haciendo ilegal, incluso con la autorización de estos, cualquier procedimiento que implique su esterilización. Sin embargo, en el contexto del trastorno de identidad o disforia de género, algunos profesionales de la medicina en Chile están recetando a NNA medicamentos y cirugías que, sobre la base del “enfoque afirmativo”, prescinde de los requisitos legales y consensuados por la bioética clínica sobre consentimiento informado y promueve iniciar tratamientos sin contar con un diagnóstico, sin evaluación de la capacidad del paciente y sin evidencia científica sobre su seguridad y efectividad. En este trabajo se argumenta que el inicio de procesos de transición de género potencialmente dañinos en menores de edad, supone desafiar la ley vigente sobre consentimiento informado y capacidad legal, así como el interés superior del niño en el contexto sanitario.

Loper Bright: Su impacto para el futuro del Derecho administrativo
Authors: Méndez Pablo
Published: January 2025

El caso Loper Bright, decidido por la Corte Suprema de Estados Unidos en junio de 2024, revocó la doctrina Chevron, asestando un golpe al Derecho Administrativo y captando la atención de culturas jurídicas a nivel global. Este artículo analiza el impacto de dicha decisión desde la perspectiva del futuro de esta área del Derecho. Revisa el trasfondo normativo del caso, abarcando el desarrollo de las agencias reguladoras y la Ley de Procedimiento Administrativo estadounidense, y ofreciendo una explicación detallada de la doctrina Chevron y los fundamentos de su revocación. Finalmente, se evalúan las implicancias de Loper Bright en el modelo del Derecho Administrativo estadounidense, concluyendo que, aunque representa un desafío importante, no supone su fin, sino un reflejo de los vaivenes políticos y constitucionales característicos del sistema jurídico en este país.
