Published: May 2024

A method is proposed for solving problems of mathematical physics for semi-infinite media containing systems of curvilinear cuts. Based on singular integral equations (SIE), a unified approach to solving the problem has been developed. Numerical implementation was carried out using parallelisation. A graph of the duration of the initial cluster hour is given for calculating an array of searched functions in the context of a parabolic form as a function of the number of processes for one variant of implementation. It is shown that the entire algorithm scales well and has an efficient number of processes. The expected result was obtained, because the structure of the calculation process in models based on SIE is mostly unchanged and built on well-defined procedures. It turned out that 150–200 processes are effective. An accuracy of 10–12 was achieved with the number of collocation points of the contour of each section N = 300, because the algorithm for numerical solution of the problem uses interpolation by Chebyshev polynomials in accordance with the fact that the unknown function has a key feature at the ends of the section, which causes a higher speed of convergence of the algorithm. The study of the question of the further increase in the accuracy of the result was not conducted. The corresponding dynamic boundary value problems for a restrained and force-free half-plane are studied. The influence of the curvature of defects, their interaction and proximity of the boundary on the magnitude and nature of the change in the dynamic stress intensity coefficients was studied. To check the reliability of the algorithm, two tests were carried out: removing three inhomogeneities at a distance of 106 of their length from each other and saturating the system by increasing the number of geometrically equal reflectors to 13–15. When removed, the characteristics of each reflector tend to the characteristics of a single one, and when saturated, they tend to the results of the corresponding periodic problem. The agreement between the results showed good reliability of the algorithm. The proposed method can be used to assess the influence of various mechanical or geometric factors on the strength of bodies with defects.

Celem artykułu jest prezentacja badań na grupie 284 młodych (do 35. roku życia), aktywnych fizycznie i kulturowo ludzi, którzy w obliczu lockdownu musieli zmienić swoje przyzwyczajenia partycypacji w rytuałach kulturowych i medialnych. Przeprowadzone badanie pozwoliło na ukazanie trwałych trendów zmian, jakie zaszły w świadomości odbiorczej. Badanie przeprowadzono w paradygmacie badań ilościowych techniką webankiety. Uzyskane odpowiedzi miały charakter deklaratywny. Z badań można wywnioskować, że lockdown w znaczący sposób zmienił podejście do serwisów streamingowych, które w dużym stopniu zastąpiły partycypację kinową. Przedstawioną tezę potwierdza przykład 113 osób deklarujących się jako kinomaniacy, tj. osoby, które uczęszczały do kina co najmniej dwa razy w miesiącu i traktowały to wydarzenie jako normalną aktywność; obecnie deklarują mniejszy udział w spektaklach kinowych (jeden raz w miesiącu) oraz wskazują na zwiększenie atrakcyjności tzw. filmów telewizyjnych. Innym przykładem zawartym w tekście jest opis funkcjonowania nowo powstałych grup sąsiedzkich jako alternatywy dla mediów lokalnych. Wnioski płynące z przeprowadzonych badań mogą posłużyć jako materiał wyjściowy do kolejnych badań prowadzonych przez badaczy z zakresu: humanistyki cyfrowej, nauk o kulturze i religii, pedagogiki medialnej oraz medioznawców badających wpływ mediów na zmiany społeczne.
Characterization of columnar BiFeO3 thick films prepared by magnetic field-assisted pulsed laser deposition

Published: May 2024

Abstract
Polycrystalline BiFeO3 thick films were prepared on Pt/TiO2/SiO2/Si substates by using magnetic field-assisted pulsed laser deposition. Columnar BiFeO3 thick films were successfully obtained with a thickness of 1.8 μm, owing to an oblique incoming flux and high deposition rate by the confinement of the plume under a magnetic field. In the columnar BiFeO3 thick films, a saturated P-E hysteresis loop was obtained at RT, and the remanent polarization (P

Post-new-horizons Orbits and Masses for the Satellites of Pluto
Authors: Brozović Marina , Jacobson Robert A. 
Published: May 2024

Abstract
We report on ephemerides for the satellites of Pluto based on the large set of astrometric measurements. Our orbit fit yielded the following masses with 1σ uncertainties: GM
Pluto = 869.3 ± 0.4 km3 s−2, GM
Charon = 106.1 ± 0.3 km3 s−2, GM
Nix = 1.50 ± 0.52 × 10−3 km3 s−2, GM
Hydra = 2.01 ± 0.27 × 10−3 km3 s−2, corresponding to the densities of ρ
Pluto = 1.853 ± 0.004 g cm−3, ρ
Charon = 1.705 ± 0.006 g cm−3, ρ
Nix = 0.88 ± 0.31 g cm−3, and ρ
Hydra = 1.21 ± 0.19 g cm−3. Masses of Kerberos and Styx remain unconstrained, and it is unlikely that we will be able to measure them even if we obtain abundant 1 mas precision astrometry during the next 20 yr. We summarize the results of orbit integration in terms of osculating and precessing ellipse model mean elements. All satellites reside in near-circular orbits, and Kerberos and Styx have 0.4 deg and 0.3 deg inclinations with respect to Charon’s orbit plane. The nodal regression periods for Kerberos and Hydra are ∼9 and ∼14 yr respectively. We found that Charon’s orbit pole can be approximated as: R.A. = 133.0073 + 0.0036T deg, and decl. = –6.2449 + 2.5 × 10−5
T deg, where T is Julian centuries from the epoch J2000, based on 5000 yr of orbit integration.
Investigating the Soft X-Ray Spectra of Solar Flare Onsets
Authors: Telikicherla Anant , Woods Thomas N. , Schwab Bennet D. 
Published: May 2024

Abstract
In this study, we present the analysis of six solar flare events that occurred in 2022, using new data from the third-generation Miniature X-Ray Solar Spectrometer, also known as the Dual-zone Aperture X-ray Solar Spectrometer (DAXSS). The primary focus of this study is on the flare’s onset phase, which is characterized by elevated soft X-ray emissions even before the flare’s impulsive phase. We analyze the temporal evolution of plasma temperature, emission measure, and elemental abundance factors during the flare onset phase by fitting the DAXSS spectra with the Astrophysical Plasma Emission Code model. The model fitting results indicate that the flaring plasma is already at a high temperature (10–15 MK) during the onset period. The temperature rises during the onset phase, followed by a decrease and subsequent increase during the impulsive phase. Elemental abundance factors show a trend of falling below preflare values during the onset phase, with some recovery before the impulsive phase. During the impulsive phase, the abundance factors decrease from elevated coronal values to about photospheric values. We also analyze images from the 193 Å channel of the Atmospheric Imaging Assembly (AIA), highlighting the formation or brightening of coronal loop structures during the onset phase. Two distinct onset loop configurations are observed, which are referred to as one-loop and two-loop onsets. Both DAXSS and AIA observations indicate that the flare onset phase exhibits hot coronal plasma properties similar to those of the impulsive phase, suggesting that the onset phase may act as a preconditioning effect for some flares.
Thermal Evolution of an Active Region Through Quiet and Flaring Phases as Observed by NuSTAR, XRT, and AIA

Abstract
Solar active regions (ARs) contain a broad range of temperatures, with the thermal plasma distribution often observed to peak in the few millions of kelvin. Differential emission measure (DEM) analysis can allow instruments with diverse temperature responses to be used in concert to estimate this distribution. Nuclear Spectroscopic Telescope ARray (NuSTAR) hard X-ray (HXR) observations are uniquely sensitive to the highest-temperature components of the corona, and thus extremely powerful for examining signatures of reconnection-driven heating. Here, we use NuSTAR diagnostics in combination with extreme-ultraviolet and soft X-ray observations (from the Solar Dynamics Observatory/Atmospheric Imaging Assembly and Hinode/X-Ray Telescope) to construct DEMs over 170 distinct time intervals during a 5 hr observation of an alternately flaring and quiet active region (NOAA designation AR 12712). This represents the first HXR study to examine the time evolution of the distribution of thermal plasma in an AR. During microflares, we find that the initial microflare-associated plasma heating is predominantly heating of material that is already relatively hot, followed later on by broader heating of initially cooler material. During quiescent times, we show that the amount of extremely hot (>10 MK) material in this region is significantly (∼2–4 orders of magnitude) less than that found in the quiescent AR observed in HXRs by FOXSI-2. This result implies there can be radically different high-temperature thermal distributions in different ARs, and strongly motivates future HXR DEM studies covering a large number of these regions.
La scène des portraits au théâtre, à la radio et à l’écran : Kenneth Branagh et cinq Hamlets sous influence
Authors: Hatchuel Sarah 
Published: May 2024

Focalisé sur la séquence des portraits (scène du boudoir, acte III scène iv, où Hamlet montre à Gertrude le portrait de son ancien mari et celui du nouveau), cet article analyse le parcours de l’acteur-auteur Kenneth Branagh à travers cinq productions d’Hamlet où il a joué le personnage éponyme (RADA 1980 ; Renaissance 1988 ; BBC Radio 1992 ; RSC 1993 ; Castle Rock Films 1996). Les séquences seront étudiées comme des carrefours d’influences contradictoires, entre interprétation violente et sexualisée (Olivier, Zeffirelli) et jeu retenu et menaçant (Kozintsev), entre prise en compte de l’expérience d’un mentor (Derek Jacobi) et fascination pour un acteur hollywoodien (James Cagney). Nous montrerons que l’interprétation de Branagh, à la fois personnelle et collective, évolue de 1980 à 1996, dans une prise en compte à la fois du médium et des multiples sources d’influence de l’acteur-auteur.

Abstract

Introduction:
Mandibular fractures are common injuries during maxillofacial trauma, and currently, open reduction and internal fixation are considered gold-standard treatments. There is a wide discussion about which plates give the best outcomes. Hence, we are conducting a biomechanical comparison of two plates for mandibular symphysis and angle fracture with finite element analysis (FEA). The aim of this study was to do a comparative study of FEA between the conventional and our new modified three-dimensional (3D) strut miniplate in mandibular fractures at symphysis and angle regions.

Materials and Methods:
Finite element models of symphyseal and angle fractures of the mandible were developed. Each fracture model was then realigned and fixed by the conventional method 2.0 mm system, and our modified 3D strut plating method 2.0 mm system followed by the analysis of various stresses developed in plates and mandibular fracture area after application of load was observed in the study.

Results:
The modified 3D strut plating system with 2.0 mm miniplates is significantly better in preventing displacement of fracture segments by better distribution of forces compared to the conventional plating system. Rest of the parameters were within the permitted limits.

Discussion:
Modified 3D strut plating method was reasonably effective and superior in managing force-displacement compared to the conventional method of fixation for comminuted and unfavourable mandibular symphyseal fracture and angle fracture.
Phylogenetic, phylogeographic and divergence time analysis of Anopheles subpictus species complex using ITS2 and COI sequences
Authors: Muthukumarana Sandaleka Lihini , Wedage Madurangi Methsala , Rathnayake Samanthika , De Silva Kolitha Nissanka 
Published: May 2024

Objective:
To address the phylogenetic and phylogeographic relationship between different lineages of Anopheles (An.) subpictus species complex in most parts of the Asian continent by maximum utilization of Internal Transcriber Spacer 2 (ITS2) and cytochrome C oxidase I (COI) sequences deposited at the GenBank.

Methods:
Seventy-five ITS2, 210 COI and 26 concatenated sequences available in the NCBI database were used. Phylogenetic analysis was performed using Bayesian likelihood trees, whereas median-joining haplotype networks and time-scale divergence trees were generated for phylogeographic analysis. Genetic diversity indices and genetic differentiation were also calculated.

Results:
Two genetically divergent molecular forms of An. subpictus species complex corresponding to sibling species A and B are established. Species A evolved around 37-82 million years ago in Sri Lanka, India, and the Netherlands, and species B evolved around 22-79 million years ago in Sri Lanka, India, and Myanmar. Vietnam, Thailand, and Cambodia have two molecular forms: one is phylogenetically similar to species B. Other forms differ from species A and B and evolved recently in the above mentioned countries, Indonesia and the Philippines. Genetic subdivision among Sri Lanka, India, and the Netherlands is almost absent. A substantial genetic differentiation was obtained for some populations due to isolation by large geographical distances. Genetic diversity indices reveal the presence of a long-established stable mosquito population, at mutation-drift equilibrium, regardless of population fluctuations.

Conclusions:

An. subpictus species complex consists of more than two genetically divergent molecular forms. Species A is highly divergent from the rest. Sri Lanka and India contain only species A and B.
Integrating the Human Dimension in Marine Spatial Planning: Lessons from Karimunjawa National Park, Indonesia

Published: May 2024

Abstract
Integrating the human dimension in Marine Spatial Planning (MSP) has been a primary challenge for MSP practices worldwide. One of the main issues in MSP is meaningful participation. However, there is an empirical gap regarding how participation functions and its relationship to achieving social sustainability goals. This paper aims to answer this question by studying MSP in Karimunjawa National Park, Indonesia. A qualitative descriptive research approach was used for the data collection and analysis. The results highlight that participation in Karimunjawa provides captivating alternatives in terms of participation, specifically in the areas of planning and management. We conclude that participation in management can mitigate the negative effects resulting from the lack of participation in planning, which may be constrained by factors such as knowledge and power gaps, as well as time limitations. The case-study findings also indicate that community responsibility towards the environment is closely related to their authority in regulating the utilisation of resources.
