With the rapid increase in the use of drones in various applications, including commercial and governmental, and the increasing probability of communication failures and contingencies, research becomes critical to ensure the safety and efficiency of their operations. The aim of this research is to develop adaptive drone flight control algorithms capable of operating effectively under conditions of limited communication and incomplete information to ensure reliable and safe autonomous operation of these systems. The applied methods include computer modelling and simulation, analytical, statistical, functional, deductive and descriptive methods. The study found that the use of performance evaluation methods for complex systems enables the identification of safety and performance criteria for drones, and drone flight control provides basic principles and methods that can be adapted for drones, including autopiloting and navigation. In addition, analyses of satellite communication and navigation prove the need to consider the limitations of this technology when developing drone control algorithms. The combination of these techniques allows for more robust and adaptive drone control systems that can function effectively in complex environments such as communication limitations and incomplete information. Additionally, it was found that the integration of adaptive control algorithms based on these methods allows drones to effectively adapt to variable environmental conditions and make decisions quickly even when communication is lost or information is limited.

Inspired by Adler’s idea on VC minimal theories [1], we introduce VC-minimal complexity. We show that for any $N\in \mathbb {N}^{>0}$, there is $k_N>0$ such that for any finite bipartite graph $(X,Y;E)$ with VC-minimal complexity $< N$, there exist $X'\subseteq X$, $Y'\subseteq Y$ with $|X'|\geq k_N |X|$, $|Y'|\geq k_N |Y|$ such that $X'\times Y' \subseteq E$ or $X'\times Y'\cap E=\emptyset $.

Paul's epistemology was famously mapped onto his eschatology by J. Louis Martyn, but it must be mapped also onto his ecclesiology. For Paul, knowing is bound always and indissolubly to living with others. To understand how Paul would have us know things, then, we must focus not on knowledge as such, but on epistemic practices in ecclesial communities. Whereas the Corinthians’ use of wisdom and knowledge made for fragmentation and dissolution in the body of Christ (1 Cor 1–4; 8–10), Paul would have practices with knowledge instantiate communion and care for one another, as is proper for Christ's body. Integral to theological knowing is a sense of what and whom theology is for, a sense being critically explored in recent evaluations of theological education.

Putting a specific value on human life is important in many contexts and forms part of the basis for many political, administrative, commercial, and personal decisions. Sometimes, the value is set explicitly, sometimes even in monetary terms, but much more often, it is set implicitly through a decision that allows us to calculate the valuation of a life implicit in a certain rule or a certain resource allocation. We also value lives in what looks like a completely different way when we evaluate whether a particular life is being or has been lived well. Both of these ways of valuing are done from an outside or third-person perspective, but there is also a third way of valuing a life which is from the first-person perspective, and which essentially asks how much my life is worth to me. Is there any connection between these different ways of valuing life, and if so what is the connection between them? This paper provides an account of John Harris’ analysis of the value of life and discusses whether it can bridge the gap between first-person and third-person evaluations of the value of life, and whether it can do so in a way that still allows for resource allocation decisions to be made in health care and other sectors.

This paper outlines the design of a six-element multiple-input–multiple-output (MIMO) antenna with pattern diversity for industrial scientific medical (ISM)/5G-enabled wireless body area networks (WBANs). Within the MIMO configuration, each element has a quasi-yagi antenna configuration implemented on an ultrathin microwave laminate. The proposed quasi-yagi antenna has a small form factor of 25 × 25 mm, featuring a dipole-like radiator excited through a microstrip-line to tapered slot-line transition. The antenna’s radiators are patterned to ensure a dual-narrow impedance bandwidth. The conventional strip-line director in the planar yagi is replaced with a semicircular loop-like director, enhancing directional radiation patterns. This proposed flexible antenna offers versatile functionality by operating at both ISM standards of 2.45 GHz and the 5G wireless local area network standard at 3.5 GHz. The quasi-yagi elements are strategically distributed in a hexagonal formation to construct the six-element MIMO scheme with pattern diversity, resulting in a tangential radiation pattern suitable for on-body communication. Following fabrication, the prototype MIMO antenna’s simulation results are validated through real-time measurements. The proposed antenna exhibits an average gain exceeding 3.5 dBi across both operating bands. Furthermore, the proposed MIMO antenna exhibits promising performance metrics suitable for densely cluttered WBAN environments.

We evaluated the viral load of varicella-zoster virus (VZV) in ambient air, vesicle, and pharyngeal swabs in VZV-infected patients. Of 46 cases, 6 had VZV detected in indoor air samples from patient rooms. Results suggest an association between viral load in the pharyngeal swab and indoor air.

Psychiatric comorbidity is common in children and adolescents with CHDs. Early recognition and evidence-based treatments are crucial to prevent long-term consequences. To support early identification and reduce stigma, we 1) developed and 2) tested the usability and acceptability of online information material on common mental health disorders targeted healthcare professionals and affected families. Website content was shaped by insights from interviews with healthcare professionals across sectors, parents, and adolescents. Evaluations demonstrated promising acceptability and usability of the first prototype but indicated the need for improvements in specific aspects of content, navigation, and overall aesthetics.

It is, perhaps, with some surprise that I find the native/non-native divide again attracting attention. The first I remember of this being an issue was when we were informed that the native speaker was dead (Paikeday, 1985). Needless to say, to those of us who did not feel at all deceased, this came as a surprise, but the announcement certainly attracted attention. The next contribution to the debate that I remember was Peter Medgyes's (1992) question regarding whether native or non-native was worth more. And so the dispute has continued spasmodically until the present, when we find two pieces on the subject within two recent issues of Language Teaching (Llurda & Calvet-Terré, 2024; Selvi et al., 2024).

Le fardeau administratif renvoie au phénomène selon lequel la mise en œuvre des politiques publiques et, plus généralement, les interactions avec l’État, sont coûteuses et difficiles. Chaque personne est en effet confrontée à des coûts d'apprentissage lorsqu'elle acquiert de l'information sur les programmes et services publics, à des coûts de conformité lorsqu'elle tente de satisfaire à leurs règles, et à des coûts psychologiques (stress, etc.) lorsqu'elle interagit avec ceux-ci. Cette littérature, presque exclusivement anglophone, s'est développée à un rythme effréné. Cette synthèse critique fait le bilan de ces récents développements et propose une discussion articulée autour de trois thèmes : 1) Que sont les fardeaux administratifs et quels enjeux soulèvent-ils? ; 2) Quelles sont les sources des fardeaux? ; et 3) Quelles en sont les conséquences distributives et politiques? Des pistes de recherche future sont proposées pour chacun de ces thèmes.
