AbstractThe advent of 5G networks has precipitated an unparalleled surge in demand for mobile communication services, propelled by the advent of sophisticated wireless technologies. An increasing number of countries are moving from fourth generation (4G) to fifth generation (5G) networks, creating a new expectation for services that are dynamic, transparent, and differentiated. It is anticipated that these services will be adapted to a multitude of use cases and will become a standard practice. The diversity of these use cases and the increasingly complex network infrastructures present significant challenges, particularly in the management of resources and the orchestration of services. Network Slicing is emerging as a promising approach to address these challenges, as it facilitates efficient Resource Allocation (RA) and supports self‐service capabilities. However, effective network segmentation implementation requires the development of robust algorithms to guarantee optimal RA. In this regard, artificial intelligence and machine learning (ML) have demonstrated their utility in the analysis of large datasets and the facilitation of intelligent decision‐making processes. However, certain ML methodologies are limited in their ability to adapt to the evolving environments characteristic of 5G networks and beyond (B5G/6G). This paper examines the specific challenges associated with the evolution of 5G and B5G/6G networks, with a particular focus on ML solutions for RA and dynamic network slicing orchestration requirements. Moreover, the article presents potential avenues for further research in this domain with the objective of enhancing the efficiency of next‐generation mobile networks through the adoption of innovative technological solutions.
Optimality conditions for global minimizers to a class of convex set optimization problem subjected to geometric constraints
Authors: Nguyen Tung , Pham Duoc , Nguyen Hoi 
Published: February 2025

In this paper, we study optimality conditions for both global and approximate minimizers to convex set optimization problems with geometric constraints. We first consider a form of Gerstewitz's nonlinear scalarization function concerning the set-less relation introduced by Kuroiwa. Then, it is employed to construct a type of directional derivative and sub-gradient for cone-convex set-valued maps. We also give some properties and usual calculus rules for these concepts. Later, some necessary and sufficient conditions for global and approximate solutions are established. Examples are provided for analyzing and illustrating the obtained results.
Ausfallhonorar in der Bestellpraxis
Authors: Brantz Alina 
Published: February 2025

ZusammenfassungDer Patient erscheint unangekündigt oder nach kurzfristiger Absage nicht zum vereinbarten Termin. Ein solcher Terminausfall führt in Arztpraxen schnell zu wirtschaftlichen Verlusten. Das Honorar dieses Termins fällt ersatzlos weg, wenn der Arzt nicht die Möglichkeit hat, den Termin anderweitig zu vergeben oder der Termin mit einer Doppelbelegung geplant ist. Die Geltendmachung solcher Schäden kommt nach den gesetzlichen Vorschriften über Dienstverträge oder bei Abschluss einer vertraglichen Vereinbarung als sogenanntes Ausfallhonorar in Betracht. Höchstrichterliche Rechtsprechung zu der Frage, ob und unter welchen Voraussetzungen ein Ausfallhonorar in Ansatz gebracht werden kann, existierte bis vor Kurzem nicht. In der amts- und landgerichtlichen Rechtsprechung bestand bereits zuvor Einigkeit über einige Punkte, die es zu beachten gilt, um ein Ausfallhonorar geltend zu machen. Zu unterscheiden ist zwischen zwei in Betracht kommenden Anspruchsgrundlagen. Zum einen die gesetzlichen Vorschriften, dort § 615 S. 1 BGB, oder zum anderen eine vertraglich geschlossene Vereinbarung können als Grundlage für die Geltendmachung dienen. Es stellen sich einige Hürden, die teilweise bereits vor dem Eintritt des eigentlichen Terminversäumnisses zu nehmen sind. Außerdem eignet sich die Geltendmachung nicht in jedem Fachgebiet und bei jeder Praxisorganisation. Erfolgsaussichten bestehen lediglich in sogenannten Bestellpraxen, also solchen Praxen, die Termine exklusiv für einzelne Patienten vergeben.

A silent opponent: Staphylococcus aureus and its
impact on wrestlers
Authors: Thomas Talia , Moore Angela , Nath Swapan , Kearns Greg 
Published: February 2025

AbstractCommunity acquired methicillin resistant Staphylococcus aureus infections
have surged dramatically over the past decade. Athletes in contact sports,
especially wrestlers, represent a unique subset of young, healthy individuals
who are at heightened risk for transmitting methicillin resistant
Staphylococcus aureus. The sport of wrestling has seen a significant
increase in participation, particularly among adolescents, underscoring its
growing popularity and the urgent need to address this issue. Unfortunately, the
rates of community acquired methicillin resistant Staphylococcus aureus
have followed a similar upward trend. Treatment options for community acquired
methicillin resistant Staphylococcus aureus vary, ranging from topical or
systemic antibiotics to more invasive interventions like incision, drainage, and
intralesional injections. Preventive measures are also essential and include
avoiding shared equipment, meticulous mat and gear cleaning, and eliminating
bacterial colonization. While existing research supports the effectiveness of
decolonization strategies in hospital settings, there is a pressing need to
adapt and implement these approaches within the wrestling community. Current
prevention methods, such as mat cleaning and skin checks before competitions,
are insufficient on their own. By adopting more comprehensive decolonization
protocols tailored to the wrestling environment, we can better protect athletes
and reduce the incidence of community acquired methicillin resistant
Staphylococcus aureus skin infections.

Published: February 2025

AbstractInterleukin-8 (IL-8) is a neutrophil chemotactic factor produced by vascular endothelial cells. This study aimed to evaluate whether the serum IL-8 level can be the biomarker for postoperative intimal hyperplasia in the rat model. Sixteen male Lewis rats (mean weight: 501 ± 44 g) were subjected in this study. The right epigastric vein graft is interposed into the common femoral artery with 10–0 interrupted sutures, as previously described. Vein grafts from each group were stained with hematoxylin and eosin and Elastica Verhoeff's van Gieson's at 2 and 4 weeks postoperatively. Unoperated right epigastric veins were also examined as a Sham. In Group edaravone, free-radical scavenger, edaravone (Radicut®, Mitsubishi Tanabe Pharma Corp., Osaka Japan) was administered, instead of saline. The initial areas of vein grafts were measured using computerized planimetry (NIH Image Ver. 1.61). Serum IL-8 levels were measured and compared using an unpaired t-test. This study was approved by the Hyogo College of Medicine Animal Research Committee (No. 235). The average intimal area at 4 weeks in Control group was significantly increased compared with that of Sham group (0.43 ± 0.11 vs. 0.00 ± 0.00 mm2, p < 0.01). The average serum IL-8 levels at 4 weeks were also significantly increased, compared with that of Sham group (148 ± 6 vs. 53 ± 14 pg/mL, p < 0.05). The serum IL-8 levels in Group edaravone were appeared to be suppressed but not significant (132 ± 24 pg/mL, p = 0.72). It is very important to detect the biomarker such as the serum IL-8, before the establishment of postoperative intimal hyperplasia.

Published: February 2025

A bunching system utilizing a heterodyne combiner is designed to generate a sawtooth waveform with three harmonics to increase the beam current intensity of medical cyclotron accelerators. The design incorporates a low-pass filter, helical bandpass filters, and a broadband matching network, producing a sawtooth waveform exceeding 1200 V, which meets the requirements for efficient bunching. This buncher substitutes the design and manufacturing requirements for high linearity broadband power amplifiers with three narrowband single-frequency power amplifiers for amplification. The digital direct synthesizer achieves coherent amplitude and phase adjustment of these three frequency signals. The broadband matching network is based on transmission line transformers to avoid the design of large-sized coaxial resonant cavities, which satisfy the spatial constraints of the cyclotron injection line.
Evaluating several dose-response curves with a common zero level
Authors: Piepho Hans-Peter , Onofri Andrea , Malik Waqas A. 
Published: February 2025

Abstract

Background
: Experiments in different fields, including ecotoxicology, crop protection and agronomy, frequently involve qualitatively different inputs that can be applied in different doses. For each input, a separate dose-response curve can be fitted. If the dose levels include zero for each treatment, the curves must pass through the same intercept. Recently, the so-called Quenouille-Addelman solution has been proposed to analyse such data. This commentary shows a simple, previously published alternative to this method that is both easier to implement and statistically more efficient.
Results:
Three examples illustrate how a linear model package can be used to efficiently analyse several dose-response curves with a common intercept.
Conclusion:
The Quenouille-Addelman solution was originally proposed before computers when fully-fledged regression analyses posed a formidable task. That method traded convenience of computation for some loss of efficiency. With the availability of good regression packages, such a trade-off has become obsolete and a fully efficient analysis is easily obtained.

Abstract

Rice productivity is low and uncertain in flood prone lowlands. Conservation of excess rainwater through proper land modification and intensive management may improve the productivity of such fragile lands. So, the impact of land modification for integrated crop-fish farming system (IFS) on improving land and water productivity was studied in 0.5 ha rainfed lowland for 6 years (2002 to 2008) at Regional Rainfed Lowland Rice Research Station, Gerua, Assam, India. Land modification for the IFS involved excavating soil for pond refuge (7% area) and two side trenches (10% area), and constructing wide dykes (23% area) on 4 sides using the excavated soil. Remaining 60% area (main field) was used for field crops. On the main field, rice was grown in wet season. In the dry season, rice was grown for the initial 3 years (2002–2003 to 2004–2005) and low duty winter crops in the latter 3 years (2005–2006 to 2007–2008). Harvested water with the IFS facilitated dry season cultivation. However, the dry season rice crop required 2 to 4 irrigations (25 to 50 cm) from an outside source and produced a grain yield at 4.36 t ha
−1
with physical water productivity of 0.49 kg m
−3
. The dry season winter crops produced rice equivalent yield at 3.07 t ha
−1
with physical water productivity of 0.68 kg m
−3
. Fish productivity was 0.89 t ha
−1
. Fish yield was 26% higher when the cropping sequence on the main field was rice-rice
vs
the rice-dry season crop. Water harvesting and multiple use of water for the IFS increased net return, land productivity, economic water productivity and sustainable yield index by 2.2, 3.8, 2.1, and 1.6 times, respectively, as compared to the conventional practice of no land modification rice-fallow. So, integrated crop fish farming system was beneficial in harvesting excess water and using it for improving land and water productivity in addition to sustainability in flood prone lowlands of eastern India.
The Slow and Resolute Resurrection of the Destination Sarajevo
Authors: Martin-Colonna Cyril 
Published: February 2025

Summary
Between 1992 and 1995, Bosnia and Herzegovina suffered a major armed conflict. This brought major disruption of the urban system to the capital, Sarajevo. This conflict caused a fracture inside the society and its urban identity. After the immediate reconstruction stage, a new process called post-conflict transition, event or disaster followed and required the collaboration of actors at multiple scales. This promoted the realization of new urban and societal projects. The tourism sector is one of these projects, creators, and carriers of new representations of the city, promoting the reconstruction of the tourist destination and the renewal of urban identity through a new tourism development of the city, which promotes the memory of the past conflict. These representations, modelled by the different urban actors (local and national, international, tourist and cultural policies), are transmitted to the tourist level through the urban space, bringing them to the attention of tourists, which can promote territorial attractiveness and economic benefits for local populations. However, following a conflict, the decision making actors of the city can make conflicting choices, particularly in the case of cities that have experienced internal conflicts. The case highlights the situation of Sarajevo between 2022 and 2024, increasingly embracing the European model of the cultural and sustainable tourist city, while preserving the memory of the past conflict, against a backdrop of political and identity crises.

Benchmark of neutral beam simulation codes with motional Stark effect for applications in ITER
Authors: Balazs Peter , von Hellermann Manfred G , Shabashov Aleksei , Asztalos Örs , Pokol Gergo I 
Published: February 2025

Abstract
Motional Stark effect (MSE) measurements have been useful for characterizing the magnetic field structure in several tokamaks over the past decades. The Stark splitting in the emission spectrum of injected high-energy neutrals carries information about both the magnetic field strength and direction, although only the directional information is extracted in most measurements. There are several codes capable of simulating the spectrum emitted by neutral beams with the MSE included, aiding the design and utilization of beam emission spectroscopy (BES) or MSE diagnostic systems. In this paper, we compare two of such codes, namely Simulation of Spectra by M. v. Hellermann and CASPER based on Cherab & Raysect, both expected to play an important role in the synthetic-diagnostic toolbox of ITER. The basis of the benchmark is an ITER scenario representative of the machine's baseline performance, with emphasis on the relation between spectral components contributing to the background and the MSE spectrum itself.&#xD;&#xD;It was found that after carefully matching the inputs of the codes, the MSE simulations show generally good agreement, apart from a known issue regarding the sigma-to-pi line ratios. In terms of the two examined background components, bulk-ion charge exchange shows an overall good agreement, while the line radiation of the SOL region mirrors some fundamental differences in the modeling in the modeling.

Abstract
CO2 hydrates show promising application in CO2 sequestration, as well as natural gas recovering from hydrate-bearing sediments, in which the stability of CO2 hydrates plays a vital role in these practical applications. Here, we report the thermal dissociation and cage transformations in polycrystalline CO2 hydrates via molecular dynamics (MD) simulations and machine learning (ML). It is revealed that the melting points of polycrystalline CO2 hydrates (PCO2H) are dictated by the microstructural cages, in which 512, 51262 and 4151063 cages predominate. Upon heating, PCO2H shows reduction trend in the number of clathrate cages, accompanied by large-scale cage reformations via 28 types of reversible/irreversible cage transformations. The cage transformations are achieved via mechanisms of removing, inserting and rotating water molecules, in which water molecules in clathrate cages substantially exchange. Cage transformations involve 512, 51262, 4151063, and 4151062 are pronouncedly frequent, acting as pivotal intermediate pathway in the thermal dissociation of PCO2H. The study provides a clear roadmap on the thermally-induced cage transformations and their mechanisms, and establishes ML frameworks to predict the dissociation behaviors in terms of melting points and melting dynamics.
Highly sensitive refractive index sensing with a perfect MIM absorber in visible to near-infrared range
Authors: Kaium Sk Md Abdul Kaium , Mollah Md. Aslam 
Published: February 2025

Abstract
An innovative metasurface refractive index sensor that operates in the visible to near-infrared (NIR) range is introduced in this work. The sensor has a unique half-ring, half-square split design which allows it to reach dual absorption peaks, resulting in near-perfect absorption values of 99.97\% in the visible range and 99.99\% in the near-infrared region. Reaching 530.05 nm/RIU for the visible spectrum's first peak and 620.24 nm/RIU for the NIR's second peak, the resonant structure has remarkable refractive index sensitivity. Additionally, the metasurface's highest figure of merit (FOM) of 13.88 RIU-1 highlights how effective it is in detecting refractive index. The sensor has a robust linear response to changes in the refractive index and functions efficiently throughout a range of 1 to 1.5. Through the utilization of both surface plasmon resonance and Fabry-Pérot cavity resonances, the device's distinct design improves light-matter interaction, which in turn increases sensitivity and absorption. Finite element method (FEM) simulations in the frequency domain revealed the optimal geometric parameters for maximum performance. With its high absorption capacity and polarization insensitivity, this unique design provides a flexible platform for use in chemical detection, environmental monitoring, and biosensing. The structure's scalability and tunability further increase its potential for useful sensing solutions in a variety of industries.

Published: February 2025

Abstract
We measured the frequency-dependent magnetization losses of twisted multifilament MgB2 wires subjected to ac transverse magnetic fields with a small amplitude, under which coupling loss dominates magnetization loss, and then, we determined their coupling time constants as well as their geometry factors of coupling losses at various temperatures. We also measured the hysteresis loops of their magnetizations using a vibrating sample magnetometer, and then, we calculated the hysteresis losses at various magnetic field amplitudes and at various temperatures. Note that such calculated values represent the hysteresis losses in completely decoupled filaments in a twisted multifilament MgB2 wire. Using these values obtained experimentally, we calculated the magnetization losses of twisted multifilament MgB2 wires under practical operating conditions, i.e., at various magnetic field amplitudes, at various magnetic field frequencies, and at various temperatures, considering the saturation of the filamentary region in the wire, which occurs at magnetic fields with high frequencies and large amplitudes.
Impact of switch overcritical regime on the output voltage and charging current in an AC field-controlled transformer-rectifier HTS flux pump
Authors: Gong Tianyong , Queval Loic 
Published: February 2025

Abstract
High-temperature superconducting (HTS) flux pumps eliminate the need for bulky current leads and high-current power supplies when charging superconducting devices. In such systems, superconducting switches are essential for optimal performance. Typically, the switch critical current is designed above a certain threshold, such as twice the load critical current, to prevent operation in the overcritical regime where the switch current exceeds its critical current. However, due to limitations in the fabrication process and potential performance degradation during operation, the switches may fail to meet this condition, leading to changes in the performance of the flux pumps. This paper experimentally investigates the impact of the switch overcritical regime on the performance of an AC field-controlled transformer-rectifier HTS flux pump, revealing that how the output voltage and charging current vary with key operating parameters, including the amplitude and frequency of the transformer primary current, as well as the amplitude, frequency, and duration of the switch electromagnet current. No-load voltage tests show that when the switch enters the overcritical regime, the output voltage decreases as the transformer secondary current increases, due to the generation of flux flow resistive after the switch is swiched off. Charging tests revealed that once the switch current reaches its critical current, the charging process halts prematurely. Afterward, increasing the electromagnet current slightly boosts load current, while increasing the transformer current significantly reduces it. Additionally, we observed that the load was charged when only the switch was powered, suggesting the possibility of eliminating the transformer power supply. Based on experimental results, it is predicted that the switch critical current must be at least 1.66 times the load critical current to fully charge the load in our flux pump.
