Back-illuminated spot mapping is essential for observations with modern spectroscopic survey telescopes. In the fiber position detection system, after the fiber view camera (FVC) detects the positions of the light spots from the robotic fiber positioners (RFPs), these positions must be mapped to the RFPs individually to complete subsequent calculations of their operational data. The back-illuminated images captured by the FVC show thousands of small light spots, each only hundreds of microns in size, randomly distributed on a completely black background, making accurate one-to-one mapping to the actual RFP positions highly challenging due to the lack of additional RFP features. This study constructs an artificial probability potential field to calculate the likelihood of each light spot appearing in the patrol area of an RFP, employing a global probability potential energy optimization method to establish the optimal mapping relationship. The proposed method successfully maps all light spots in the closed-loop fiber positioning task and is ultimately applied to the fiber positioning system of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope, achieving accurate mapping of 4000 RFPs on the focal plane. This algorithm effectively addresses challenges such as multitarget interference, uniform background, and RFP failures, providing a reliable approach for mapping the back-illuminated points of tens of thousands of dual-rotation RFPs without requiring special backlight designs in future spectral survey telescopes.
Blowing Out the Candle: How to Quench Galaxies at High Redshift—An Ensemble of Rapid Starbursts, AGN Feedback, and Environment
Authors: Kimmig Lucas C. , Remus Rhea-Silvia , Seidel Benjamin , Valenzuela Lucas M. , Dolag Klaus , Burkert Andreas
Published: January 2025

Recent observations with JWST and the Atacama Large Millimeter/submillimeter Array have revealed extremely massive quiescent galaxies at redshifts of z = 3 and higher, indicating both rapid onset and quenching of star formation. Using the cosmological simulation suite Magneticum Pathfinder, we reproduce the observed number densities and stellar masses, with 36 quenched galaxies of stellar mass larger than 3 × 1010
M
⊙ at z = 3.42. We find that these galaxies are quenched through a rapid burst of star formation and subsequent active galactic nucleus (AGN) feedback caused by a particularly isotropic collapse of surrounding gas, occurring on timescales of around 200 Myr or shorter. The resulting quenched galaxies host stellar components that are kinematically fast rotating and alpha-enhanced, while exhibiting a steeper metallicity and flatter age gradient compared to galaxies of similar stellar mass. The gas of the galaxies has been metal enriched and ejected. We find that quenched galaxies do not inhabit the densest nodes, but rather sit in local underdensities. We analyze observable metrics to predict future quenching at high redshifts, finding that on shorter timescales <500 Myr, the ratio M
bh/M
* is the best predictor, followed by the burstiness of the preceding star formation, t
50–t
90 (time to go from 50% to 90% stellar mass). On longer timescales, >1 Gyr, the environment becomes the strongest predictor, followed by t
50–t
90, indicating that at high redshifts the consumption of old gas and lack of new gas are more relevant for long-term prevention of star formation than the presence of a massive AGN. We predict that relics of such high-z quenched galaxies should best be characterized by a strong alpha enhancement.
Morphological and molecular identification of Particolored bat (Vespertilio murinus) in South Korea: A first record
Authors: Kim Bong Kyun , Shim Jeong Hun , Kim Sun Sook , Eo Soo Hyung
Published: January 2025

Background

Vespertilio murinus belong to the genus Vespertilio and are widely distributed in Europe, the Middle East and Northeast Asia, Recently, the presence of the V. murinus has been confirmed in Japan, suggesting the possibility of its habitation on the Korean Peninsula. However, ecological information regarding its presence in the Korean Peninsula is extremely limited.

New information

In an urban area of Sejong City, South Korea, a bat within the genus Vespertilio was rescued by personnel of the Chungnam Wild Animal Rescue Center. The bat, which was believed to have been hibernating on an exterior wall of a building, was initially identified as Vespertilio sinensis. However, the confirmed presence of two pairs of nipples raised the possibility that the bat was a specimen of V. murinus. The measurement of the forearm length (FAL) of this bat was 45.67 mm, which is within the 95% confidence interval of the previously reported FALs of V. murinus. Additionally, the results of mtDNA sequence analysis indicated that the rescued bat could be differentiated from the closely-related species V. sinensis with respect to the sequences of 13PCGs, COI, Cytb and ND1. Finally, phylogenetic analysis revealed that this bat clustered in a clade with previously described V. murinus. Collectively, these findings provided convincing evidence to indicate that the rescued individual was a V. murinus, marking the first recorded observation of this species in South Korea.
Stinging predatory journals: a brief overview and recommendations
Authors: Larson Adam , Shelomi Matan
Published: January 2025

Predatory journals exploit the open access model for profit, often publishing papers with minimal or nonexistent peer review. Predatory publishing stings can identify predatory publishers and increase awareness of the problem, but there are no guidelines for effective stings. We propose that stings should include peer review red flags that would stop the sting from being accepted by reputable journals, be followed by a public sting statement to alert others to the predatory journal identified and predatory publishing in general, and avoid both payment to predatory publishers and risk to the stinger.
A new species of supergiant Bathynomus A. Milne-Edwards, 1879 (Crustacea, Isopoda, Cirolanidae) from Vietnam, with notes on the taxonomy of Bathynomus jamesi Kou, Chen & Li, 2017
Authors: Ng Peter K. L. , Sidabalok Conni M. , Nguyen Thanh Son
Published: January 2025

A new supergiant species of Bathynomus A. Milne-Edwards, 1879 from Vietnam is described. Bathynomus vaderisp. nov. is characterised by its wide, rectangular clypeal region with parallel lateral margins, concave distal margin, and narrowly acute apex; the distally narrowing and posteriorly curved coxa of pereopod 7; and the presence of 11 upwardly curved pleotelson spines. The new Bathynomus is the fourth species with upwardly curved pleotelson spines and the second supergiant in the South China Sea. The taxonomy of B. jamesi Kou, Chen & Li, 2017 from the South China Sea is also discussed based on a large series of specimens. Previously reported differences in body form and pleotelson spines, which suggest that there may be two forms or species, are regarded as intraspecific variation for the time being. The contemporary culinary trend and fishing of Bathynomus in Vietnam, which have contributed to this discovery, are also discussed.
The properties on F-manifold color algebras and pre-F-manifold color algebras
Authors: Ding Ming , Chen Zhiqi , Li Jifu
Published: January 2025

The concept of F-manifold algebras is an algebraic expression of F-manifolds. In this paper, we provide the definition of an F-manifold color algebra, which can be viewed as a natural generalization of an F-manifold algebra. We develop the representation theory of an F-manifold color algebra and show that F-manifold color algebras admitting non-degenerate symmetric bilinear forms are coherence F-manifold color algebras. The concept of pre-F-manifold color algebras is also presented, and using this definition one can construct F-manifold color algebras. These results extend some properties of F-manifold algebras.
Chaotic performance and circuitry implement of piecewise logistic-like mapping
Authors: Chen Caiwen , Lu Tianxiu , Gao Ping
Published: January 2025

Discrete chaotic systems are now a meaningful research area due to their intricate dynamical characteristics. This paper introduces a novel piecewise logistic-like mapping chaotic system and rigorously establishes its Devaney chaoticity through mathematical proofs. Experimental findings demonstrate that, compared to the traditional logistic mapping, the logistic-like mapping exhibits more complex dynamic behaviors, such as bifurcation diagram, Lyapunov exponents, permutation entropy, sensitivity, and distribution of function sequences. Furthermore, in order to implement the suggested new chaotic system, a simulation circuit is designed, and a PSIM simulation model is established to validate feasibility of the simulation circuit.

La recherche agronomique en contexte de crise : cas du PITAG en Haïti
Authors: Augustin Pierre Garry
Published: January 2025

Dans cet article, nous avons analysé le cas d’un ensemble d’activités de recherche agronomique conduites dans le cadre d’un programme de recherche-formation-vulgarisation implémenté en Haïti, en pleine situation de crise multidimensionnelle. L’article donne un premier bilan des conséquences de cette dernière sur les capacités et résultats de recherche. S’appuyant sur les activités du Programme d’Innovation Technologique en Agriculture et Agroforesterie du ministère de l’Agriculture co-financé par la BID/GAFSP/FIDA, il montre que la pandémie de Covid-19, la situation sociopolitique, la crise sécuritaire de 2020 à 2024 ont eu des répercussions importantes sur la recherche, mais que les acteurs du système d’innovation haïtien ont démontré une résilience étonnante et ont apporté des réponses appropriées aux problèmes identifiés. Les résultats ont été assez conséquents : entre autres 8 diagnostics agro-socio-économiques réalisés, 39 paquets techniques adaptés mis au point et prêts à être diffusés auprès des agriculteurs, un renforcement conséquent des capacités des structures de recherche, publications scientifiques sous formes d’articles et de posters, 11 mémoires de Master et 5 thèses de doctorat, un laboratoire de culture in vitro installé ainsi que 9 stations agro climatiques, des répertoires des produits et des paquets techniques élaborés ainsi qu’un document de capitalisation de l’expérience (appelé programme de Recherche-Formation-Vulgarisation) destiné aux universités…). Mais on ne peut ignorer les limites (un recul insuffisant, un manque d’exhaustivité…) qui invitent à entreprendre d’autres études en vue de mettre en évidence les possibilités qui se sont présentées pendant et après les crises en vue de réorienter le système d’innovation national, tirer les leçons des différentes expériences de façon à rendre le système plus résilient et plus durable encore, élaborer/adopter des politiques visant à renforcer sa capacité de réaction en cas de nouvelles crises (ou de leur approfondissement) et évaluer la pertinence de les adapter à d’autres contextes.

Authors: Corrales Andrés Jiménez , Seyfarth Matthías Pelz
Published: January 2025

Limón es una provincia de Costa Rica que desde la construcción del Estado-nación se le ha asignado simultáneamente una condición periférica instrumental y un papel central dentro del desarrollo capitalista costarricense. En este artículo interesó interpretar las políticas de espacio diseñadas y materializadas, en el pasado y presente, con el fin de comprender los modos en los que el desarrollo geográfico desigual produce espacios periféricos y funcionales. Para ello se analizaron las escalas regional y urbana de estos procesos, partiendo del hecho de que un espacio no se puede entender aisladamente sino hay que analizarlo en sus interrelaciones. A nivel metodológico se realizó una investigación documental por medio de una revisión bibliográfica a profundidad de estudios especializados sobre la historia de Limón; así como una sistematización de normativa (leyes y decretos), informes, comunicados de prensa, documentos de proyectos de infraestructura y gestión territorial, prensa escrita, y páginas web de instituciones públicas y de empresas. Se concluye que las políticas de espacio implementadas Limón han producido desigualdades e injusticias espaciales que deben ser conocidas y cuestionadas en aras de construir futuros y geografías más justas.

Authors: Triastuti Warlinda Eka , Suprapto Suprapto , Hani Regeta Salsabila Putri , Lestari Helia Dewi
Published: January 2025

It is important for consumers to be aware of the source of gelatin due to religious restrictions, as pork is forbidden for consumption by Muslims and Jews, and cows are forbidden for consumption by Hindus. Fishery waste, such as fish bones and scales, can be a promising alternative raw material for gelatin production, as they are halal for consumption. The process of gelatin preparation involves several stages, including pretreatment, degreasing, demineralization, and hydrolysis using bromelain enzyme. hydrolysis process using bromelain enzyme ranging from 1, 2, 3, 4, 5, 6 and 7% at 300 rpm and temperature 55 °C. Hydrolysis was carried out for 6 hours and 9 hours for each concentration. Characterizations of gelatin was conducted for pH, water content, ash content, Fourier Transform-Infrared Analyzer (FTIR), X-ray Fluorescence (XRF) Spectrometry and Gas chromatography (GC). Based on the research, the optimum conditions for produce halal gelatin from red snapper scales was obtained at 5% bromelain enzyme for 9 hours for hydrolized collagen to gelatin with a yield of 11.414%, pH of 5.3, water content of 7%, ash content of 2.1%, and free from alcohol and heavy metals. The FTIR spectra show that the absorption at wavenumber 2944.5, 1628.74, 1524.55, and 1332.14 cm-1 respectively, indicating the presence of C–H, C=O, C=C and C–N stretching. The presence of absorption peaks of that functional groups show gelatin has been formed. XRF analysis show the absence of heavy metals as Hg, Pb, Cd, and Zn. Fish-based gelatin in this study is produced through a halal process, using halal ingredients, and its product does not contain alcohol, thus the gelatin produced in this study is a halal product.

Authors: Agherdien Nuraan
Published: January 2025

Orientation: More Muslim women are entering the labour market, and this requires an understanding of the cultural and social contexts as there may be challenges inhibiting their growth and advancement.Research purpose: The purpose of this article is threefold: (1) to explore the perceptions of Muslim women relating to career success; (2) to identify the challenges facing Muslim women and (3) to describe the organisational culture as experienced by Muslim women in the South African workplace.Motivation for the study: Literature often focusses on the challenges women face in general, yet little examines the challenges experienced by Muslim women in the work context. This article seeks to identify whether the challenges experienced are similar or whether specific interventions are required to ensure the career success of Muslim women.Research approach/design and method: A qualitative research design was employed using open-ended questions in an online survey as the data collection tool. Data were collected from 88 Muslim women across industries, professions and provinces within South Africa.Main findings: Experiences of success focus on happiness, contentment and growth, whereas perceptions of success in the organisation are objective and include promotion, financial gain and status. The key challenges can include a lack of resources and support; however, respondents reported mostly a positive organisational culture supporting career and personal aspirations.Practical/managerial implications: Enhancing cross-cultural awareness and understanding contributes to the experienced career success of Muslim women.Contribution/value-add: The findings propose interventions to advance the career, wellness and overall experiences of Muslim women.
Migrant churches and reverse mission: Missiological gaps and missionary trap
Authors: Musoni Phillip
Published: January 2025

The migration of Zimbabweans in search of better opportunities has spurred the growth and spread of Zimbabwean Churches within diaspora communities. Currently, many Zimbabwean churches like other African Churches have crossed continental borders, setting up branches in Europe and North America. This phenomenon of African Churches engaging with diasporic communities has been described by scholars as a ‘Reverse Mission’. A critical question that emerges is: To what degree is the establishment of African churches in other nations and continent an indicative of a reverse mission? The case study focuses on two Zimbabwean churches that have established branches in South Africa and other countries both within and beyond the African continent. The selection of the two churches is based on their origins that trace back to South Africa, rendering them pertinent examples for discussion in the context of reverse mission. The research identified ‘missiological gaps’ leading to a ‘missionary trap’ in the context of reverse mission, as the two Zimbabwean Churches face new frontiers. The article discusses how Zimbabwean churches, along with other African churches in the diaspora, created obstacles that impeded the dissemination of the gospel because of their insufficient cross-cultural training and experience. The researcher utilised descriptive phenomenological and interpretive phenomenological approaches for data collection and analysis, respectively.Intradisciplinary and/or interdisciplinary: The article is framed within the context of reverse mission, missiology, and the history of African Christianity. It contends that the African church should reassess its evangelistic strategies as it transcends national and international borders.

Aim:

The aim of the study was to evaluate the effect of indomethacin in postoperative pain when used as an irrigant.

Methods:

Sixty patients fulfilling the criteria to undergo root canal treatment were randomly divided into two groups. Group 1 consisted of routine irrigation regimen, whereas Group 2 consisted of routine irrigants and 1% indomethacin. Pain levels before root canal treatment were documented for all the patients utilizing a Visual Analog Scale (VAS). Irrigation protocol was followed as mentioned above for the respective groups. Postoperative pain was recorded after 24, 48, and 72 h for all the patients using VAS. Pain scores were examined with Shapiro–Wilk test and P < 0.05 was considered statistically significant.

Results:

Group 2 demonstrated a significant drop in postoperative pain.

Conclusion:

It was observed that there was a noteworthy reduction in postoperative pain when indomethacin was used as an irrigant.
Tourette Syndrome: An Update
Authors: Ghosh Debolina , Ghosh Debabrata
Published: January 2025

Tourette syndrome is defined as the presence of multiple motor and at least one vocal tic, lasting >1 year with onset <18 years. Disabilities may stem not only from tics but also from comorbidities, such as attention-deficit hyperactivity disorder, obsessive-compulsive disorder, anxiety, learning difficulties, and poor social skills among others. After the first description of nine cases in 1885 by George Gilles de la Tourette, until 1972, this condition was considered psuchogenic. Haloperidol was the first medication used to treat tics in 1961. The etiopathogenesis, genetics, or diagnostic biomarkers are still unclear. Habit reversal therapy is the most effective behavioral intervention for tics. Treatment medications include central alpha-2 stimulators, such as guanfacine or clonidine, dopamine receptor blockers, such as haloperidol, pimozide, or aripiprazole, and dopamine depleters, such as tetrabenazine or deutetrabenazine. Botulinum toxin is used in persistent focal/segmental drug-resistant tics. Deep brain stimulation is reserved only for adults with medically intractable tics.
Assessment of Nonmotor Symptoms in Myasthenia Gravis: Fatigue and Disease Burden
Authors: Ala Rahmi Tümay , Bulut Onur , Şengün İhsan Şükrü
Published: January 2025

ABSTRACT

Background:

Patients with myasthenia gravis (MG) experience fatigue throughout their lives, making it essential to distinguish fatigue from muscle weakness. We aimed to provide information about fatigue, its prevalence, its relation to personal and disease-specific factors, and the possible burden of the disease.

Subjects and Methods:

Fifty-three patients with MG who presented to our Neuromuscular Clinic between 2020 and 2022 were enrolled in the study. Patients were in pharmacologic remission or at the minimal manifestation stage according to the Myasthenia Gravis Foundation of America treatment status scale. A definitive diagnosis was based on a positive antibody test, a decrement response in repetitive nerve stimulation tests, and/or increased jitter or block on a single nerve fiber test in electromyography. To confirm a myasthenic exacerbation or crisis, the need for rescue treatment was assessed. Patients were divided into two groups based on whether they received rescue treatment. The Checklist for Individual Strength-Fatigue (CIS) questionnaire, the Quality of Life Questionnaire on Myasthenia Gravis (MG-QoL) assessment of fatigue, and the Quantitative Myasthenia Gravis Score for neurologic examinations were used.

Results:

The average fatigue score was 72, leading to 84% of patients being classified as fatigued, with a cutoff value of 40. The myasthenic crisis group exhibited worse CIS-total, CIS-physical fatigue, and CIS-subjective perception scores, as well as poorer quality of life scores, compared with the other patients. Opinions on the disease burden may vary because all the patients were in remission.

Conclusion:

Patients who experienced more crises throughout the course of the disease were in a more morbidity and had a greater disease burden compared with those who experienced fewer or no crises during remission periods. Fatigue represents a concept distinct from the muscle weakness detected during physical examinations; it significantly impacts patients’ daily lives and serves as a strong indicator of disease burden.
Comparison of Three Surgical Approaches for the Treatment of Lumbar Spinal Stenosis: Total Laminectomy, Unilateral Approach for Bilateral Decompression, and Total Laminectomy with Posterior Transpedicular Screw Fixation
Authors: Barutçuoğlu Mustafa , Mete Mesut , Unsal Ulkun Unlu , Gurgen Arzu İlbay , Duransoy Yusuf Kurtuluş
Published: January 2025

ABSTRACT

Introduction:

Lumbar spinal stenosis (LSS) is one of the most common diseases for spinal surgery and many surgical techniques are used for treatment.

Objective:

The aim of this retrospective study was to observe the clinical and radiological results of total laminectomy (TL), unilateral approach for bilateral decompression, and posterior transpedicular fixation–interbody fusion with TL.

Materials and Methods:

The data of 112 patients who underwent surgical treatment for LSS with different surgical techniques were reviewed retrospectively. The patients were divided into 3 groups according to the surgical technique. In the first group, patients underwent TL, in the second group, patients underwent bilateral decompression via unilateral hemilaminectomy, and in the third group, patients underwent posterior transpedicular fixation–interbody fusion with TL. Preoperative and postoperative evaluations were done by visual analog scale (VAS) and functional back pain scales (FBPSs). Furthermore, three groups were compared in respect of operation time, bleeding, and complications.

Results:

The difference between preoperative and postoperative VAS and FBPS scores were statistically significant in all groups. Operation time, bleeding, and hospital stay were greater in fusion group than decompression-alone groups. The VAS improvement rate was 66%, 70%, and 62% in Group 1, Group 2, and Group 3, respectively. In addition, improvement of FBPS scores between preoperative and postoperative period was statistically significant for the three groups (P < 0.05).

Conclusion:

Decompression with fusion surgery had no significant difference compared with decompression alone in patient’s clinical outcome and safety.
The role of magnesium sulphate in pain management in trauma patients
Authors: Abdelhalim Tasneem I. , Amin Sabry M. , Ahmed Sameh A. , Eid Ahmed I. , Aboelnasr Roeya M.
Published: January 2025

Background

Intravenous magnesium sulphate (MgSO4) decreases opioid consumption and side effects. As an adjuvant, magnesium improves the analgesic effects of more well-known analgesics even though it is not a main analgesic.

Aim

Look at how MgSO4 helps trauma patients who have been hospitalized to the ICU manage their pain.

Patients and methods

This study had 50 patients of both sexes who were hospitalized with musculoskeletal trauma and a revised trauma score of 12 if their pain score was greater than or equal to 5. The study was prospective, controlled, randomized, and double-blinded. Two equal groups were formed out of the patients: group B got 100 ml of normal saline, whereas group A received 30 mg/kg of diluted MgSO4 in 100 mlof normal saline. Both groups had been given over 1 h and repeated every 12 h from admission till 48 h.

Results

The experimental group’s average 48 h morphine dosage intake, ICU stay, and hospital stay were all considerably less than those of the group under control (P<0.05). The two groups’ numerical rating scales did not differ from one another. Heart rate, systolic and diastolic blood pressure, mean arterial blood pressure, respiratory rate, and oxygen saturation were all a little different between the two groups. The death rate did not appear to differ between the two groups.

Conclusions

MgSO4 was an effective agent for analgesia in trauma patients as it significantly reduced opioid consumption and was associated with lower ICU and hospital stays.

Authors: Wang Yunying , Liu Guoqing , Wu Chongming , Wang Xiaoyu , Long Xianmei , Xie Shouqi , Nan Youping , Tan Qingsong
Published: January 2025

The aim of this study was to assess the optimal protein level for grass carp when using Chlorella vulgaris meal (CVM) as a sole protein source. Six diets (CVM35, CVM42, CVM49, CVM55, CVM62, and CVM69) with varying protein levels (21.51%, 24.95%, 29.16%, 32.75%, 36.79%, and 39.74%, respectively) were fed to triplicate tanks with 30 fish each (7.0±0.1 g) for 8 weeks. Results indicated the FBW and SGR increased first and then plateaued as dietary protein level increased, while the FR plateaued first and then decreased. The FE and HSI increased linearly with dietary protein level, while VSI and MFI decreased linearly (P<0.05). As dietary protein level increased, serum IgM and GSH-Px first increased and then decreased, and peaked in the CVM55 group, while MDA showed the opposite trend. High protein diets (CVM62 and CVM69) significantly activated mTOR signaling and altered fish proximate composition. Moreover, optimal protein diet enhanced fish hardness and regulated the expression of genes associated with myosin types (myh7, myh1, myh2, and myh4) and muscle development (MRFs, FGF6s and mstn). An optimal dietary protein level of 36.54% was recommended for juvenile grass carp based on the SGR using CVM as protein source.
Топология несущих многообразий регулярных гомеоморфизмов с седлами коразмерности один
Authors: Osenkov Evgenii Mikhailovich , Pochinka Olga Vital'evna
Published: January 2025

В данной статье рассматриваются регулярные гомеоморфизмы на топологических $n$-многообразиях (не обязательно ориентируемых), являющиеся обобщением диффеоморфизмов Морса-Смейла. Под регулярным гомеоморфизмом понимается гомеоморфизм топологического $n$-многообразия ($n\geq 3$), цепно рекуррентное множество которого конечно и гиперболично (в топологическом смысле). Гиперболическая структура периодических точек позволяет классифицировать их по индексам Морса (размерности неустойчивого многообразия). При этом точки экстремальных индексов называются узловыми, а остальные - седловыми. Авторами доказано, что несущее многообразие любого регулярного $n$-гомеоморфизма, все седловые точки которого имеют индекс Морса $n-1$, гомеоморфно $n$-сфере. В размерности $n=1$ аналогичная задача не имеет смысла, поскольку окружность - единственное замкнутое 1-многообразие. Регулярные 2-гомеоморфизмы существуют на любых поверхностях, и все их седловые точки имеют индекс Морса 1, откуда следует, что полученный результат не верен в размерности 2.

О кинематическом доказательстве каноничности переменных Андуайе
Authors: Neishtadt Anatolii Iserovich
Published: January 2025

Дается кинематическое доказательство каноничности переменных Андуайе в динамике твердого тела. Это доказательство основано на подходе "возможных вращений", предложенном А. Андуайе. Отличие от исходного доказательства Андуайе состоит в том, что связанная с твердым телом система координат не предполагается системой главных осей инерции и не используются явные формулы для кинетической энергии тела, включающие моменты инерции. Предлагаемое простое доказательство представляется полезным при изложении динамики твердого тела в курсах теоретической механики.

Blood Transfusions for Chronic Malaria Anemia in Prisoners of War on the Thai–Burma Railway 1943–1945
Authors: Payne Madeleine , Gorsky Martin , Sutherland Colin J. , Shanks G. Dennis
Published: January 2025

Allied prisoners of war (POWs) working on the Imperial Japanese Army’s railroad from Thailand to Burma during 1943–1945 devised a blood transfusion service to rescue severely ill fellow prisoners who were otherwise unlikely to survive the war. Extant transfusion records (1,251 recipients, 1,189 donors) in ledger books held by the United Kingdom National Archives at Kew were accessed and analyzed. Survival to the end of the war in 1945 was determined from Commonwealth War Graves Commission records. The records examined indicate that freshly donated whole blood was manually defibrinated and transfused after crossmatches based on POW medic sera. Overall survival to the end of the war was 74% in recipients and 88% in donors. Postwar survival rates were significantly higher for transfusion recipients with malaria (89.3%) than for other diagnoses: 52.6% for malnutrition, 59.3% for dysentery, 67.2% for skin ulcers, and 75.4% for other causes (odds ratio: 3.97; 95% CI: 2.79–5.28; P <0.0001). By 1945, the vast majority of blood transfusions were given for severe anemia caused by chronic relapsing vivax malaria. Although the POW situation was admittedly extreme, our data provide evidence that blood transfusions to treat severe anemia were associated with higher survival among patients with Plasmodium vivax infection than among those with other morbidities.
Regular Model Checking Upside-Down: An Invariant-Based Approach
Authors: Esparza Javier , Raskin Michael , Welzel-Mohr Christoph
Published: January 2025

Regular model checking is a technique for the verification of infinite-state systems whose configurations can be represented as finite words over a suitable alphabet. The form we are studying applies to systems whose set of initial configurations is regular, and whose transition relation is captured by a length-preserving transducer. To verify safety properties, regular model checking iteratively computes automata recognizing increasingly larger regular sets of reachable configurations, and checks if they contain unsafe configurations. Since this procedure often does not terminate, acceleration, abstraction, and widening techniques have been developed to compute a regular superset of the reachable configurations. In this paper, we develop a complementary procedure. Instead of approaching the set of reachable configurations from below, we start with the set of all configurations and approach it from above. We use that the set of reachable configurations is equal to the intersection of all inductive invariants of the system. Since this intersection is non-regular in general, we introduce b-invariants, defined as those representable by CNF-formulas with at most b clauses. We prove that, for every $b\geq0$, the intersection of all inductive b-invariants is regular, and we construct an automaton recognizing it. We show that whether this automaton accepts some unsafe configuration is in EXPSPACE for every $b\geq0$, and PSPACE-complete for b=1. Finally, we study how large must b be to prove safety properties of a number of benchmarks.

En este esclarecedor estudio sobre la criminalidad juvenil en Perú, se examinan los crecientes niveles de delincuencia impulsados por el sicariato y la extorsión, principalmente ejecutados por menores de edad. Esta obra revela las deficiencias del sistema de justicia penal juvenil en el Distrito Judicial de Lima y su impacto en el tratamiento de adolescentes infractores. A través de un diseño fenomenológico y una investigación no experimental que incluyó la perspectiva de 100 expertos legales, se establece una correlación moderada entre las deficiencias del sistema y la participación juvenil en el crimen organizado (Rho de Spearman = .529). El texto aboga por la necesidad de un enfoque legal reformado que priorice la rehabilitación y reintegración, garantizando los derechos de los adolescentes al tiempo que se combate eficazmente la participación de menores en la delincuencia. Esta obra es una llamada urgente a la reforma del sistema penal juvenil en Perú para prevenir futuras injusticias y promover un cambio social significativo.
Innovations and Challenges in the Preservation of the Batak Language by the Protestant Batak Christian Huria Church (HKBP) among Youth in the Context of Urbanization in Jakarta
Authors: Hotmauli Sihombing Tetty
Published: January 2025

In the dynamic urban context of Jakarta, the preservation of regional languages faces significant challenges, especially among the younger generation. This study examines the role of the Huria Christian Batak Protestant Church (HKBP, a Protestant Batak Christian Church) in maintaining the existence of the Batak language in the midst of urbanization, by applying social identity theory to understand the dynamics of language preservation and cultural identity. Using a qualitative approach, the study involved in-depth interviews with 30 young congregations and 10 key HKBP figures, as well as participatory observation of church activities over a six-month period. The results of the analysis revealed that HKBP's main efforts in preserving the Batak language are centered on the use of the language in worship, with 75% of respondents stating the importance of this practice. The study also identified several additional initiatives, such as cultural seminars, cultural performances, and the use of traditional musical instruments in worship. The main challenges faced include the low enthusiasm of the younger generation (60% of respondents), the pressure of assimilation of metropolitan culture, and the limitations of effective preservation programs outside the context of worship. The findings emphasized the importance of developing more comprehensive and innovative strategies, including the potential use of digital technology and social media, to increase the appeal of the Batak language among urban youth. This research results in a religious community-based language preservation model that can be applied in urban contexts, offering a new perspective in urban sociolinguistic studies and cultural diversity management. The strategic recommendations are prepared to maximize the role of religious institutions as agents of cultural preservation, with a focus on synergy between churches, families, and urban Batak communities. This study highlights the potential and challenges of religious institutions in bridging tradition and modernity, as well as maintaining cultural identity amid urban social complexity. Although limited to the context of HKBP in Jakarta, these findings provide valuable insights for the study of minority language preservation in urban environments more broadly
"Vyhublé postuláty rozumové víry."
Authors: Sirovátka Jakub

In his late magnum opus, Auch eine Geschichte der Philosophie, Jürgen Habermas seeks to reconstruct what the “post-metaphysical” age lost when it abandoned metaphysics. Habermas sees a fundamental bifurcation of metaphysical thought in the eighteenth century, namely in the parting of the ways represented by David Hume and Immanuel Kant. In my paper, I will particularly focus on Habermas’s critique of Kant’s philosophy of religion. As a first step, I will present his critical conception of Kant’s practical philosophy in conjunction with his philosophy of religion, which, according to Habermas, fails in its attempt to rescue religious contents within a secular philosophy. The crucial weakness that Habermas identifies in Kant’s systematics is the demands that arise from the absolute validity of the moral law. I will then, in a second step, critically discuss this interpretation of Habermas, attempting to point out the weaknesses of his interpretation. In contrast to Habermas’s attempt, however, I am convinced that the philosophy of religion is a constitutive and plausible part of Kant’s philosophy.
Nietzsche o Kantovi
Authors: Sikora Ondřej
Published: January 2025

To what extent is Nietzsche’s critique of Kant empty rhetoric, and to what extent is it a substantive argument to be taken seriously? Within the broad Nietzschean- Kantian polemics, the study is concerned with the ethical domain. It starts from the title phrase “the Chinese of Königsberg” (“Das Königsberger Chinesenthum”) found in Nietzsche’s late book The Antichrist, and goes back to earlier forms of Kant-critique. At its core is the universalist, uniforming claim of the categorical imperative expressed by the motif of duty, and its broader framework is a dualist notion of reality with the postulated noumenal sphere. The aim of the paper is not to offer a clear resolution to the dispute but to highlight its inspirational moments: these include the negative, refuting emphasis in the foundation of ethics and personal autonomy as the basis of self-respect and duty in both protagonists. The Kantian perspective can integrate Nietzsche’s “autonomy of the body” into the autonomy of pure practical reason.

Measuring the Reproducibility of Scientific Research Based on Computing Environment Provisioning Methods (SDG)
Authors: Gomes Daniel Adorno , Mestre Pedro , Serôdio Carlos
Published: January 2025

Objective: This study investigates three different methods for provisioning computational environments in scientific research, focusing on the level of reproducibility offered by each one. The methods are manual setup, container-based, and one based on Infrastructure-as-Code principles, the Environment Code-First (ECF) framework.
 
Method: The methodology adopted for this research comprises a comparative study design evaluating three distinct approaches to computational environment provisioning: manual setup, container-based setup, and the ECF framework. The study involved reproducing a research experiment using the Inception-V3 model to identify canine hip dysplasia from X-ray images across different computational setups. Data was collected through performance metrics such as reproducibility rate, consistency of results, and ease of setup.
 
Results and Discussion: The results revealed that while offering complete control over the environment, the manual setup needed to be more consistent and more accessible to reproduce, leading to variability in the results. The container-based method improved reproducibility but required manual intervention to set up the container infrastructure. The ECF-based approach, however, demonstrated superior performance by fully automating the environment provisioning process, ensuring 100% reproducibility and consistency across different platforms.
 
Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied to advance practices in computational research and scientific reproducibility. These implications could encompass the broader adoption of IaC tools in scientific experiments, potentially leading to more reliable and reproducible research outcomes.
 
Originality/Value: This study contributes to the literature by highlighting the innovative application of the Infrastructure-as-Code approach to achieving reproducibility in scientific research. The potential impact of adopting IaC tools on improving the reliability and consistency of research outcomes evidences the relevance and value of this research.
