Parameter‐free predictive control with flexibility in power adjustment for grid‐connected converters under unbalanced grid conditions
Authors: Jabbarnejad Alireza , Vaez‐Zadeh Sadegh , Khalilzadeh Mohammad 
Published: June 2024

AbstractThis paper introduces a novel finite control set predictive direct power control method for grid‐connected converters without cost function evaluations. Unlike conventional predictive direct power control, since the proposed method does not use the model parameters, their uncertainties do not cause prediction error and inappropriate voltage vector selection. The method employs a new form of voltage vector selection based on the slopes of active and reactive powers. The slopes are predicted in a manner with a low sensitivity to sampling noise, without updating a look‐up table, and recursive methods. Hence, there are no stagnation and convergence issues. Also, the proposed method avoids startup problems caused by data‐lacking due to directly regulating the active and reactive power by a switching logic. Flexible power oscillations control with balanced sinusoidal grid currents without any signal sequence extraction can also be achieved under this method in unbalanced grid conditions. The proposed method is assessed by both simulation and experimental studies, and its performance is compared with existing robust combined and model predictive control methods. The outcomes highlight the influence of the proposed approach and establish its superiority over the other considered methods.

Published: June 2024

AbstractIn recent years, wide voltage range DC/DC converters have been widely used in telecom power, solar generation and electric vehicle charger applications. Based on this, a new multi‐resonant converter with wide input voltage is proposed here. Compared with the traditional LLC converter, the proposed converter can maintain the output voltage within a narrow frequency regulation range in both under‐resonance and over‐resonance areas. Thus, a wide voltage range can be realized without additional switch components or complex control strategies. The topology and the corresponding working principle of the proposed converter are introduced. In addition, the equivalent model by considering the fundamental wave is established and the influence of the resonance parameters on the voltage gain characteristic is analysed in detail. With these considerations, the resonance parameters are designed. Finally, a 500 W experiment platform is established to verify the effectiveness and feasibility of the proposed converter.
Quantum algorithm for bioinformatics to compute the similarity between proteins

Published: June 2024

AbstractDrug discovery has become a main challenge in the society, following the COVID‐19 pandemic. However, pharmaceutical companies are already using computing to accelerate drug discovery and are increasingly interested in quantum computing (QC), with a view to improving the speed of development process for new drugs. The authors propose a quantum method for generating random sequences based on occurrence in a protein database and quantum algorithms for calculating a similarity rate between proteins. Both concepts can be used for structure prediction in drug design. The aim is to find the proteins closest to the generated protein and obtain an ordering of these proteins. First, the authors will present the construction of a quantum protein generator that defines a protein, called a test protein. The authors will then describe different methods to compute the similarity's rate between each protein in the database and the test protein or, for a case study, the elafin. The algorithms have been extended or adapted to a quantum formalism for use cases, that is, amino acid sequences, and tested to see the added value of quantum versions. The interest is to observe whether QC can be used in the drug discovery process.

Published: June 2024

Context. The measurement of the internal rotation of post-main-sequence stars using data from space-based photometry missions has demonstrated the need for an efficient angular momentum transport in stellar interiors. No clear solution has emerged so far, and it remains a challenge for stellar modellers to explain the observed trends.
Aims. We constrained the shape of the internal rotation profile of six Kepler subgiants that were studied in details in 2014 and also the properties of the missing angular momentum transport process that acts in stellar interiors from Markov chain Monte Carlo (MCMC) inversions of the internal rotation.
Methods. We applied a new MCMC inversion technique to existing Kepler subgiant targets and tested various shapes of the internal rotation profile of the six subgiants that were observed in 2014. We also constrained the limitations on the number of free parameters that can be used in the MCMC inversion, showing the limitations in the amount of information in the seismic data.
Results. First, we show that large-scale fossil magnetic fields are not able to explain the internal rotation of subgiants, similarly to what was determined from detailed studies of Kepler red giants. We are also able to constrain the location of the transition in the internal rotation profile for the most evolved stars in the available set of subgiants. We find that some of them exhibit a transition that is located close to the border of the helium core, but one object exhibit a transition located much higher in radius.
Conclusions. We conclude that various processes might be at play that would explain our observations, but a consistent detailed modelling of all available subgiants is required to reveal the physical nature of the angular momentum process, in particular, for the least evolved objects. In addition, it is paramount to increase the number of stars for which these inferences are possible (e.g. with the future PLATO mission) because they play a key role in validating candidates for the transport process.

AbstractDiagnostic routine and knowledge about the therapy regimes of infectious diseases
like malaria gain in importance due to globalization, global warming, and
increasing numbers of refugees. We report a case of a 66-year-old patient who
presented with severe abdominal pain, most prominent in the left upper abdomen.
He was recently hospitalized with severe falciparum malaria, diagnosed after
returning from a trip around the world. Upon readmission, laboratory results
showed post-artesunate delayed hemolysis. The ultrasound examination was highly
suspicious of splenic rupture, confirmed by the immediately performed CT scan.
In this case, the prompt diagnosis allowed the initiation of adequate
conservative therapy including intensive care monitoring and hemodynamic
stabilization.

Inpatients with Severe Behavioral and Psychological Symptoms of Dementia: A
Retrospective Study

Published: June 2024

Abstract
Introduction While antipsychotics are often prescribed for behavioral and
psychological symptoms of dementia (BPSD), typically on an off-label basis,
these medications have serious adverse effects. This study investigated the
long-term use of antipsychotics among inpatients with dementia displaying severe
BPSD, focusing on how prescriptions change over time.
Methods Medical charts at Kusakabe Memorial Hospital were retrospectively
reviewed from October 2012 to September 2021. The study included patients
diagnosed with dementia, admitted for BPSD, and were continuing antipsychotics
at 3 months of their admission. Antipsychotic dosages were categorized as high
(≥300 mg/d), medium (100–300 mg/d), and low (<100 mg/d) based on
chlorpromazine equivalents and tracked until 15 months during hospitalization.
Binary logistic regression was used to identify factors associated with dosage
reductions between months 3 and 6.
Results This study involved 188 patients, with an average age of 81.2
years, 67% of whom were diagnosed with Alzheimer&apos;s dementia. At 3
months, 15.4% were taking high, 44.1% on medium, and 40.4% on low dosages of
antipsychotics. The highest average dosage was observed at 3 months, with a
subsequent decrease over time. By the 12th month, 20–30% of patients in all
dosage categories had stopped their antipsychotic medication. Significant
factors for dosage reduction included higher initial doses (OR 1.003, 95%Cl:
1.001–1.006, P=0.01) and male gender (OR 2.481, 95%Cl: 1.251–4.918,
P=0.009).
Discussion A trajectory of antipsychotic dosage in inpatients with severe
BPSD has rarely been reported. This research emphasizes the need for
personalized strategies in managing long-term pharmacotherapy for this
vulnerable group of patients.
Stellungnahme der Wissenschaftlichen Fachgesellschaft und des Berufsverbandes zur Notfallversorgung in der Hals-Nasen-Ohren-Heilkunde

Published: June 2024

ZusammenfassungDie Ereignisse bezüglich einer Reform der Notfallversorgung überschlagen sich, und ein klares Konzept ist noch nicht erkennbar, wenngleich überfällig. Kliniken und Praxen erleben im Fachgebiet der Hals-Nasen-Ohrenheilkunde (HNO) einen deutlichen Zuwachs entsprechender Patienten, die Gründe sind mannigfaltig: von dem Bedürfnis Betroffener einer sofortigen Abklärung bestimmter Symptome bis hin zu veränderten Notdienststrukturen. Verschärft hat sich die Situation durch das jüngste Urteil zur Sozialversicherungspflicht der Poolärzte mit einer „Notbremse“ im ärztlichen Bereitschaftsdienst bspw. der Kassenärztlichen Vereinigung (KV) Baden-Württemberg. Zu allem Überfluss wurde die vom Gemeinsamen Bundesausschuss erstellte Erstfassung der Richtlinie zur Ersteinschätzung des Versorgungsbedarfs in der Notfallversorgung (Ersteinschätzungsrichtlinie) durch das Bundesministerium für Gesundheit beanstandet und liegt aktuell auf Eis. Es ist allen Akteuren klar, dass in jedem Fall eine grundlegende Reform zur Filterung und Steuerung der Patientenströme notwendig wird. Die Vorschläge reichen von einer Aufklärung der Bürger zur Erlangung einer basalen Gesundheitskompetenz über die Wiedereinführung der Notfallgebühr bis hin zu den wahrscheinlichen Szenarien einer zentralen Notfallnummer, eines gemeinsamen Tresens (i.e. vertragsärztliche Notfallpraxis und entsprechende Klinik-Notfallambulanzen in unmittelbarer räumlicher Nähe) und einer Triage durch geschultes Personal mit Vergabeoptionen in die geeigneten Versorgungsbereiche. Die Regierungskommission für eine moderne und bedarfsgerechte Krankenhausversorgung hat mit Stellungnahmen zur Reform der Notfall- und Akutversorgung zu den Bereichen „Rettungsdienst und Finanzierung“ und „Integrierte Notfallzentren und Integrierte Leitstellen“ Empfehlungen abgegeben. Hierzu sollen a.e. im Verlauf des Jahres, nach Möglichkeit unter Beteiligung der Fachgesellschaften und Berufsverbände, belastbare Grundlagen geschaffen sein, auch verknüpft mit der Hoffnung, die dringend notwendige Entlastung von medizinischem Personal in Klinik und Praxis einzuleiten.Das vorliegende Manuskript beschreibt die gesundheitspolitische Historie sowie aktuelle Probleme der Notfallversorgung, wobei Lösungsvorschläge mit Bezug auf die HNO-ärztlichen Besonderheiten in den Fokus genommen werden. Das vorliegende Positionspapier ist verbunden mit einem Appell an Selbstverwaltung und Politik, nunmehr zeitnah ein tragfähiges Konzept für die Notfallversorgung in Kraft zu setzen, da Finanzierung und Personalverfügbarkeit immer kritischer werden und der ungeregelten Welle an Notfallpatienten eine ordnende Hand gereicht werden muss.

Abstract
C-Aryl glycosides have attracted considerable interest as biologically active natural products and as O-aryl glycoside mimetics in drug discovery. Here, we describe a straightforward synthesis of C-aryl glycosides by photoredox/Ni dual-catalyzed reductive cross-coupling between glycosyl bromides and aryl bromides. This methodology enables a highly α-stereoselective synthesis of C-aryl glucosides, galactosides, and mannosides.
A Homolytic Substitution Approach for Directing Group-Free Nickel-Catalyzed Dialkylation of Unactivated Alkenes
Authors: Koh Ming Joo , Cong Fei , Ng Jun Wei 
Published: June 2024

AbstractThe selective construction of two C(sp3)–C(sp3) bonds through trimolecular cross-coupling of unactivated alkenes remains one of the most difficult challenges in organic synthesis. Despite previous advances in metal-catalyzed coupling for the dicarbofunctionalization of alkenes, dialkylation is still problematic due to the instability of the requisite metal–alkyl intermediate, which undergoes facile β-hydride elimination or protodemetalation. Recently, our group was successful in developing a bimolecular homolytic substitution (SH2) strategy that circumvents metal–alkyl side reactions and accomplishes the challenging cross-coupling of metal–alkyl intermediates with alkyl radicals in the absence of a directing auxiliary, permitting a highly regioselective dialkylation of unactivated alkenes.1	Introduction2	Nickel-Catalyzed Dicarbofunctionalization of Unactivated Alkenes3	Nickel-Catalyzed Dialkylation of Unactivated Alkenes4	Conclusions and Perspectives
The impact of real-time ultrasound guidance on ventricular catheter placement in cerebrospinal fluid shunts – a single-center study
Authors: Sarikaya-Seiwert Sevgi , Schievelkamp Arndt-Hendrik , Born Mark , Wispel Christian , Haberl Hannes , Shabo Ehab 
Published: June 2024

Abstract
Purpose Misplacement of ventricular catheters during shunt surgery occurs in 40% of cases using a freehand technique and therefore represents a risk for early shunt failure. The goal of this retrospective, single-center study is to analyze the impact of real-time ultrasound guidance on ventricular catheter positioning and early outcome of shunt survival.
Materials and Methods We analyzed the charts and images of all patients who underwent shunt surgery from 09/2017 to 12/2022 and compared the position of the ventricular catheter using the freehand technique and real-time ultrasound guidance. Central catheter position was graded as grade I (optimal), II (contact with ventricle structures or contralateral), and III (misplacement).
Results A ventricular catheter was placed in 244 patients using real-time US guidance and in 506 patients using a freehand technique. The mean age (53.4 and 53.6 years, respectively) and the preoperative frontal occipital horn ratio (FOHR; 0.47 versus 0.44) were almost equal in both groups. In the study group, grade I catheter position was achieved in 64% of cases, grade II in 34%, and grade III in 2%. The control group showed grade I position in 45%, grade II in 32%, and grade III in 23% of cases (p<0.05). An early central catheter failure rate was the highest in grade III (40.5%) compared to 4% in grade I.
Conclusion Our data demonstrate that real-time US guidance leads to a significant improvement in ventricular catheter placement. Consequently, early shunt revisions decrease significantly. Further prospective, randomized, and controlled studies comparing the standard method to real-time ultrasound catheter placement are required.

Authors: Carvajal Jose , Timko Sarah , Kim Stanley E. , Lewis Daniel D. , Lee Hae Beom 
Published: June 2024

Abstract
Objective The aim of this study was to assess the feasibility and accuracy of femoral stem placement for total hip arthroplasty (THA) using three-dimensional (3D)-printed custom surgical guides (CSGs).
Study Design Computed tomography (CT) scans of 7 cadaveric adult medium-sized (23.2–30.0 kg) dog femurs were acquired. A virtual plan was made using 3D models, and CSGs were designed to aid in optimal femoral stem positioning. Two surgeons with limited experience in THA performed stem implantation with CSGs for each limb. Following stem implantation, CT scans were repeated, and final stem alignment was measured and then compared with the preoperative virtual plan.
Results The median difference between planned and postoperative stem alignment with CSGs was –6.2 degrees (interquartile [IQR] –15.2 to 2.1 degrees) for stem version, 2.3 degrees (IQR –0.6 to 3.9 degrees) for varus/valgus angulation, and 1.8 degrees (IQR –0.1 to 2.9 degrees) for cranial/caudal stem angulation. The median difference in stem depth was 1.5 mm (IQR –1.2 to 3.1). Mean surgical procedure time for CSG surgeries was 44.1 ± 20.5 minutes for femoral stem implantation.
Conclusion The use of CSGs resulted in successful femoral stem placement by two novice THA surgeons. Novice THA surgeons may benefit from CSGs in the learning stages of THA, but further investigation is recommended prior to clinical implementation.
Paternalistic AI: the case of aged care
Authors: Voinea Cristina , Wangmo Tenzin , Vică Constantin 
Published: June 2024

AbstractIn this paper, we argue that AI systems for aged care can be paternalistic towards older adults. We start by showing how implicit age biases get embedded in AI technologies, either through designers’ ideologies and beliefs or in the data processed by AI systems. Thereafter, we argue that ageism oftentimes leads to paternalism towards older adults. We introduce the concept of technological paternalism and illustrate how it works in practice, by looking at AI for aged care. We end by analyzing the justifications for paternalism in the care of older adults to show that the imposition of paternalistic AI technologies to promote the overall good of older adults is not justified.
The impact of religiosity and financial literacy on financial management behavior and well-being among Indonesian Muslims

Published: June 2024

AbstractThis study examines the effects of religiosity and Islamic financial literacy on Muslims’ financial behavior and well-being. Additionally, it investigates the impact of sociodemographic variables on the centrality of religiosity, financial literacy, financial management behavior, and the well-being of Muslim consumers. This research integrates perspectives from Rational Choice Theory, the Rational Choice Theory of Religion, and Behavioral Finance to illuminate the mechanisms behind these relationships. Data were collected through a non-probability sampling method from 1141 Muslim individuals aged between 18 and 65 living in Indonesia. The results indicate that the centrality of religion in the lives of Muslim consumers and Islamic financial literacy significantly affects their financial management behavior and financial well-being. However, the empirical evidence suggests a more substantial effect of Islamic financial literacy than religiosity on both dependent variables.

Background Live fuel comprises a significant portion of the fuel consumed in forest and scrub crown fires. However, its flammability remains poorly understood. Although live fuel differs from dead fuel in moisture content, chemical composition, cellular structure and physiological characteristics, its higher moisture content masks the effect of other characteristics on its flammability. Aims The aim of the study was to delineate and assess the effects of live/dead condition, moisture content and particle size on flammability of gorse (Ulex europaeus L.). Methods Live and dead gorse material of three size classes (0–3, 3–6, and 6–10 mm in diameter) at six moisture contents (0, 10, 25, 50, 75 and 100%) was tested in a cone calorimeter to evaluate its flammability using new sample preparation and moisture conditioning techniques. Key results On average, live fuel ignited 21% slower, reached 11% higher peak heat release rate, and had a 12% shorter burn duration than dead fuel of the same moisture content. These differences were most pronounced in coarser material. Conclusions For gorse, fine dead fuels increase the likelihood of ignition, fine live fuels contribute to high burning intensities, and coarser live and dead fuels prolong combustion. Implications These findings highlight the need to account for flammability differences between live and dead fuels in fire behaviour models beyond those driven by variations in moisture content.
Towards a realistic dipole cosmology: the dipole ΛCDM model
Authors: Ebrahimian Ehsan , Krishnan Chethan , Mondol Ranjini , Sheikh-Jabbari M M 
Published: June 2024

AbstractDipole cosmology is the maximally Copernican generalization of the FLRW paradigm that can incorporate bulk flows in the cosmic fluid. In this paper, we first discuss how multiple fluid components with independent flows can be realized in this set up. This is the necessary step to promote ‘tilted’ Bianchi cosmologies to a viable framework for cosmological model building involving fluid mixtures (as in FLRW). We present a dipole ΛCDM model which has radiation and matter with independent flows, with (or without) a positive cosmological constant. A remarkable feature of models containing radiation (including dipole ΛCDM) is that therelativeflow between radiation and matter can increase at late times, which can contribute to e.g. the CMB dipole. This can happen generically in the space of initial conditions. We discuss the significance of this observation for late time cosmic tensions.
Moving mirrors and event horizons in non-flat background geometry
Authors: Ievlev Evgenii 
Published: June 2024

Abstract
Moving mirrors have been used for a long time as simple models for studying various properties of black hole radiation, such as the thermal spectrum and entanglement entropy. These models are typically constructed to mimic the collapse of a spherically symmetric distribution of matter in the Minkowski background. We generalize this correspondence to the case of non-trivial background geometry and consider two examples, the Schwarzschild—de Sitter black hole and the Bañados–Teitelboim–Zanelli (BTZ) black hole. In the BTZ case we were also able to show that this approach works for the spinning black hole which has only axial symmetry.
