Perspective Chapter: The Neuropsychological Dimension of Psychosis – Implications for Assessment and Treatment
Authors: Moza Sotiria , Chrysostomou Savvina
Published: February 2025

Psychotic Spectrum Disorders (PSDs) affect approximately 1 in 300 people worldwide and encompass a range of positive symptoms, such as hallucinations, delusions, and disorganized thinking, as well as negative symptoms, including alogia, avolition, and diminished emotional expression. In addition, people with PSDs frequently present impairments in cognitive domains, such as executive function, memory, attention, and social cognition, which lead to difficulties in independent living, employment, and interpersonal relationships. This chapter explores the neuropsychological dimension of psychosis and provides a thorough summary of the cognitive deficits linked to PSDs. The neurobiological underpinnings of these impairments are discussed, examining PSD differentiations in brain structure and function. Instruments used for neuropsychological evaluation in PSDs are presented, supporting the crucial role formal evaluation plays in diagnosis and treatment. Modern therapeutic modalities, such as cognitive remediation therapies, pharmaceutical interventions, and technologies like neurostimulation and digital therapeutics, are discussed. The chapter closes by discussing implications for future study and clinical application, highlighting the necessity of integrated, culturally relevant, and ethical approaches for cognitive rehabilitation and symptom management. Through this work, the authors aim to support a better understanding of psychosis and promote more efficient, comprehensive care for people with PSDs.

Published: February 2025

Viruses are widely present in nature and can infect eukaryotic cells, producing a variety of biological effects. Several viruses are capable of coexisting with human cells over the long term, and it has been proven that these viruses possess carcinogenic properties. Radiation therapy is a common method used for treating tumors. Under the influence of radiation, infected tumor cells and uninfected tumor cells exhibit different pathological characteristics and treatment outcomes. Herein, in this chapter, we discuss the impact of five viruses on tumor radiation therapy, including coronavirus disease-2019 (COVID-19), hepatitis B virus (HBV), human papillomavirus (HPV), monkeypox virus, and avian influenza virus. We hope that by summarizing the relationship between viral replication and tumor radiation therapy, we can provide novel insight for future treatments.

Le langage symbolique : une méthode en théologie
Authors: Mulolwa Jonathan Kashindi
Published: February 2025

Les écrivains bibliques ont coutume de recourir au symbolisme pour assurer que la saisie de leur message soit facilitée. En se focalisant en particulier sur le quatrième évangile du Nouveau Testament, l’auteur lève le voile sur le caractère énigmatique de la christologie johannique qui paraît déconcertante pour le lecteur non averti à cause du caractère imagé que revêtent les appellations de Jésus : comme langage parabolique et allégorique, comme métaphore et symbole. Cette étude montre que le symbolisme n’est pas une formulation conceptuelle obscure et incomprise du public, mais au contraire que les théologiens devraient dans leurs discours de chaque jour être en mesure de trouver des formulations symboliques, afin de traduire l’exactitude de la vérité éthique et religieuse à transmettre. Bien compris ce langage est un outil d’enseignement fidèle à la méthode de transmission biblique et un véhicule sémantique d’une efficacité pédagogique inégalée.

Published: February 2025

Ecological researchers and decision - makers, with few exceptions, have failed to adopt an integrated and multidisciplinary approach to analyzing the relationship between human action and the ecological systems that sustain it; although specialization is of vital importance for the systemic progress of knowledge, there is also the need for a generalizing vision, which integrates different fields of knowledge, to create bridges, in particular, between the social sciences and the natural sciences. According to the official rhetoric, which can be found in international documents, the changes in the climate system represent direct and immediate evidence of the negative consequences that atmospheric pollution generated by human activities creates on the entire environment. On the other hand, other authors state that climate warming is an exaggeration, its effects are far from only negative, the limits of the planet are far from being reached, and the gloomy forecasts are nothing more than alarmist scenarios stimulated by certain top industries or financial interests.

The present work proposes a foray into the magic of Easter, one of the most important Christian holidays, which, not coincidentally, is celebrated in the spring, when nature is reborn. For Christians, the Resurrection of Jesus represents the victory of light over darkness, life over death and hope over despair. Like other Christian holidays, the Easter ones also bring a series of customs, superstitions and popular traditions with ancient origins, preserved with sanctity to this day. We will pay attention to the traditions of Easter, briefly presenting the main symbols that accompany this Christian holiday: the candle, the red or painted egg, pasca, the lamb, etc.
Orbit Manoeuvre Strategies for Very Low Earth Orbit (VLEO) Satellites under Solar Activity and Drag Effects
Authors:   Politecnico di Milano, Chen Sui , Athreyas Kashyapa Bramha Naren , Lansard Erick ,   Nanyang Technological University
Published: February 2025

Very Low Earth Orbits (VLEOs) offers an alternative solution to ease the congestion in LEO. Being closer to the Earth, satellites operating in VLEO benefit from enhanced ground image resolution, improved communication link-budgets and lower signal transmission latencies. However, they also experience significantly larger atmospheric drag that will quickly lead to orbital decay, due to the much denser atmosphere present in VLEO. Another challenge associated with operating in VLEO is the large modelling error of atmospheric density. This paper focuses on analysing the feasibility of operating a satellite in VLEO, by predicting its orbital decay trajectories and subsequently proposing thrusting strategies for orbit maintenance. A 180 kg satellite with a dual-thruster electric propulsion system launching in November 2025 at 300 km altitude is considered. The solar activity, a significant factor in modelling atmospheric density, is forecast based on observation data from past solar cycles. The upcoming Solar Cycle 25 is expected to have a peak strength similar to that of Solar Cycle 23. Under the effect of perturbations, the satellite’s orbital decay trajectory is simulated, and the satellite is predicted to de-orbit about 2 months after its initial launch in the absence of active orbit maintenance. To maintain the satellite at its desired operational altitude, thrust is applied to counteract perturbations. The required ΔV and thrusting frequency are computed for a range of desired altitudes and altitude drop thresholds. For a fixed value of threshold altitude drop, the thrust magnitude is also calculated for a range of firing durations. This paper provides a comprehensive understanding of a VLEO satellite’s behaviour and demonstrates the feasibility of operating a satellite in VLEO for a realistic lifetime. The results are expected to provide insightful guidance for mission designers and facilitate the advancement of more VLEO missions in the future.

Nutritional and toxicological evaluation of wild edible plants from north-east India: Impact of various cooking methods
Authors: Seal Tapan , Chaudhuri Kausik , Pillai Basundhara
Published: February 2025

This study aimed to explore the nutritional value, anti-nutritional factors, mineral content, and in vitro toxicity of ten wild edible plants from the North-Eastern region of India, including Meynia laxiflora, Castanopsis indica, Docynia indica, Flemingia vestita, Bauhinia purpurea, Dillenia pentagyna, Diplazium esculentum, Elaeagnus latifolia, Elaeagnus pyriformis, and Fagopyrum cymosum. The impacts of cooking techniques including boiling and microwaving were also investigated in the study. Nutritional analysis assessed fat, protein, fibre, carbohydrate, and mineral content in both raw and cooked samples. The anti-nutritional properties were evaluated by measuring the content of cyanogenic glycosides, oxalates, tannins, saponins, and phytates. In vitro toxicity was assessed through haemolytic assays on rat erythrocytes, cytotoxicity was measured using the MTT assay, and genotoxicity was evaluated using the comet assay. The findings revealed that both cooking methods reduced ash, fat, mineral content, anti-nutritional factors, and plant toxicity. At the same time, increasing the relative concentration of fibre and carbohydrates due to water loss or the breakdown of other components, the absolute content of these nutrients remained unchanged. Microwave cooking significantly enhanced the measured protein content (p<0.05), with increases ranging from 9.58% to 33.95%. This effect is likely due to structural modifications in the proteins caused by microwave treatment, which enhance their availability or digestibility rather than increasing the actual protein content, whereas boiling caused a reduction in protein levels, ranging from 9.66-23.25%. Additionally, microwave cooking resulted in lower mineral losses than boiling and was more effective in reducing anti-nutritional factors and toxicity (p<0.05). As a result, microwaving is recommended to improve nutritional quality, reduce fat content, and decrease anti-nutritional components and toxicity. Toxicity studies at the cellular and genomic levels indicated that these plants are safe for consumption.
Les maisons d'écrivains : un patrimoine au service de la littérature
Authors: Laplace-Claverie Hélène , Vanderpoorte Thibault
Published: February 2025

De plus en plus plébiscitées par le grand public, les maisons d’écrivain attirent chaque année un nombre croissant de visiteurs. Mais la recherche universitaire a-t-elle quelque chose à dire de ces objets culturels qui sont aussi des biens patrimoniaux et des « produits » touristiques ?

Tel est l’enjeu porté par le laboratoire ALTER (Arts/Langages: Transitions & Relations) de l’UPPA qui a choisi d’étudier pendant trois ans l’ensemble des maisons d’écrivain de la région Nouvelle-Aquitaine. À travers une approche interdisciplinaire (littérature, histoire, histoire de l’art, architecture, sociologie, géographie, muséologie, économie et droit), le projet se focalise sur la maison d’écrivain comme lieu de mémoire et de transmission, au croisement des notions de patrimoine matériel et de patrimoine immatériel.
Once Populist, Now Mainstream?
Authors: Aust Helmut Philipp , Krieger Heike
Published: February 2025

The heydays of international law are over - that much is suggested by politicians and political observers in Germany. Those who still argue in favour of an international order based on international law seem unprepared for a world of autocrats and transactional deals. Allegedly, they fail to realize the need to protect and prioritize national interests. International legal practices are even perceived as immoral when authoritarian states rely on international law to oppose foreign policy decisions of democratic states, as exemplified by recent proceedings before international courts on the war in Gaza. For a long time, international law was almost idealized in German debates, but now something seems to be shifting.

Published: February 2025

One of the variants of the Tsigai sheep is the reddish-headed and -legged, small-sized, so-called Redface Covasna. In 2014, the Institute for Farm Animal Gene Preservation brought in a small herd of these from Transylvania with the aim of national conservation of the breed.
The aim of the study is to characterize the maternal background and maternal genetic diversity of the Red-faced sheep of Covasna. For this, the nucleotide sequence of the control region (CR) of the mitochondrial genome (mtDNA) was used. The sampling was achieved from 34 individuals 2021 and 2022.
The length of the aligned CR sequences is 621 bp with the number of polymorphic base sites 88. The number of haplotypes is 30 (from haplogroups A and B, which proves its origin in Asia Minor). The value of haplotype diversity (Hd) is 0.991, and its variance is 0.010. The mean of the nucleotide diversity (π) and the average nucleotide difference per pair (k) in the investigated flock are 21.27*10-3 and 13.21, respectively. The value of the Tajima D test (-1.4427, p > 0.10) does not indicate a lack of alleles, nor does it indicate a narrowing of the genetic diversity occurring in the history of the population.

Straipsnio tikslas – parodyti modernios Lietuvos sulietuvinimo ir kultūrėjimo proceso tęstinumą pasitelkus Lietuvos kultūros politikos raidos analizę. Kultūros politika analizuojama iš istorinės perspektyvos, remiamasi įvairių socialinių tyrimų duomenimis. Bibliotekos ir kultūros centrai laikomi vienomis svarbiausių institucijų, įgyvendinančių valstybės kultūros politikos tikslus.Atlikta analizė leidžia teigti, kad dabartinė Lietuvos kultūros politika užtikrina ne tiek Lietuvos sulietuvinimo ir kultūrėjimo plėtrą, galinčią atremti globalizacijos iššūkius, kiek esamos padėties stabilumą. Pozityvių pokyčių kultūros politikoje stoka, turint omenyje ir įvairių institucijų bendradarbiavimą, ir veiklos koordinavimą, optimizavimą bei kultūros įstaigų veiklos regionuose didesnį rėmimą, didina recesijos, t. y. lietuvių nutautėjimo ir nukultūrėjimo, grėsmę.
Įtvirtinant monokultūrinį tautiškumą transatlantinėje erdvėje: etnokultūrinio atgaivinimo ir diasporos nacionalizmo atvejai Lietuvoje ir JAV
Authors: Čiubrinskas Vytis
Published: February 2025

Straipsnyje nagrinėjamas etnonacionalizmo fenomenas totalitarizmo ir imigraciniuose kontekstuose. Pagrindinis tikslas – paanalizuoti du lietuviškumo įtvirtinimo atvejus: XX a. 7–9 dešimtmečio etnokultūrinio atgaivinimo judėjimą bei XX a. 5–9 dešimtmečio diasporos (tėvyninį) nacionalizmą. Abiem atvejais tautiškumą siekta įtvirtinti įprasminant nacionalistinį sentimentą ir įveiksminant (etno)kultūrinį bei (etno)nacionalinį identitetą politikose, kurių epicentre atsiduria monokultūrinis – viena tauta – viena kultūra – tautiškumo modelis. Šis modelis sėkmingai priešpriešinamas tiek sovietinio totalitarizmo, tiek ir homogenizuojančio amerikietiškojo „išlydančiojo katilo“, o vėliau ir daugiakultūriškumo atžvilgiu.

Socialinių įmonių, kaip socialinės ekonomikos elemento, atsiradimas ir raida siejami su plintančia pažeidžiamų gyventojų grupių, tarp jų ir neįgaliųjų, socialine integracija. Pažymėtina, kad socialinės ekonomikos vienetų, kuriuos apibendrintai galima vadinti socialinėmis įmonėmis, plėtra skirtingose Europos šalyse vyko gana spontaniškai sprendžiant vietos lygmens socialines-ekonomines problemas, pvz., netenkinantį socialinių paslaugų lygį, atsirandančią socialinę diferenciaciją ir spaudimą socialinio aprūpinimo sferoms. Straipsnyje* siekiama nuodugniau aptarti socialinių įmonių reiškinį, remiantis užsienio autoriais, apibrėžti socialinių įmonių tikslus, formas bei jose taikomus integracijos per užimtumą būdus. Prieinama išvada, kad socialinės įmonės Europoje, priklausydamos apsaugoto užimtumo sektoriui, vaidina svarbų vaidmenį pažeidžiamų gyventojų grupių integracijos procese, tačiau jų veikla bei finansavimo mechanizmai regiono ir nacionalinio ūkio mastu turėtų būti derinami su ekonominio konkurencingumo principais, siekiant išvengti socialinėse įmonėse dirbančiųjų asmenų diskriminacijos bei neigiamų pasekmių ūkio subjektams, kurie nepriklauso remiamo užimtumo sektoriui.
LC-MS/MS METHOD FOR THE DETERMINATION OF IMATINIB MESYLATE IN BLOOD PLASMA SAMPLES AFTER ADSORPTION BY COPPER TANNIC ACID
Authors: Faraj Russol Abdul Salam , Noor H. K. , Jamel Saba H. , Jamur Jasim M. S.
Published: February 2025

A novel metal-organic framework (MOF) sorbent based on tannic acid/copper (TA/Cu) was synthesized and characterized for the application of the anticancer drug imatinib (IMA) from biological samples. The TA/Cu MOF was prepared via a facile coordination reaction and thoroughly characterized by SEM, XRD, and FTIR techniques. Critical parameters influencing the extraction efficiency of imatinib mesylate (IMAM), including pH, ionic strength, desorption solvent, and adsorption-desorption time were optimized. With acetonitrile as the desorption solvent, the method demonstrated a broad linear range of 0.55-300 μg L-1 under ideal conditions. Limits of detection and quantification were found to be 0.16 μg L-1 and 0.55 μg L-1, respectively. For plasma samples spiked at clinically relevant concentrations (5, 20, and 50 μg L-1), the sorbent showed good reusability over four cycles and negligible matrix effects. In comparison to previously published methods, the developed dispersive solid phase extraction method based on TA/Cu MOF performed better in terms of simplicity, enrichment factor, and analytical figures. Another objective of this study was to develop a liquid chromatography with tandem mass spectrometry technique that could be commonly and readily used for therapeutic drug monitoring of imatinib following extraction by solid phase extraction (SPE). Therapeutic monitoring applications can reliably quantify IMA in complex biological matrices as a result of the fast dispersive solid phase extraction (DSPE) procedure and environmentally friendly sorbent.

EFFICIENCY OF CARBON FIBER EXTRACTION BY LOW-TEMPERATURE SOLVOLYSIS
Authors: Trukhinov Denis K. , Lebedeva Elena A. , Ivanova Elena V. , Istomina Tatiana S. , Astaf’eva Svatlana A.
Published: February 2025

The paper presents the results of a comprehensive study of the effect of the structure of carbon fibers and the type of the initial polymer composite on the quality of the reclaimed fiber obtained by low-temperature solvolysis. The characteristics of the initial and reclaimed carbon fibers were analyzed using a wide range of experimental methods, including structural (X-ray diffraction analysis, scanning electron microscopy, Raman spectroscopy) and thermal studies. Solvolysis was carried out in a mixture of H2SO4 (conc.):H2O2 (conc.): H2O in a mass ratio of 2.5:3:1, respectively, at the boiling point of the solution. The recycling time was 1 h with a solution change every 20 min. The results of electron microscopy showed that, regardless of the type of polymer system, there are practically no binder residues on the surface of the fibers. Using thermal analysis, it was shown that the main mass loss of all samples of the reclaimed fiber occurs at temperatures above 600 ° C. Despite the fact that origin fibers with a smooth surface show greater thermal stability than those with a relief structure (mass loss temperature of 5% - 650°C and 620°C, respectively), extracted fibers based on the same brand have lower mass loss values. In order to assess the destructive effect of the solvolysis solution during extraction, the structural changes in the carbon fiber surface were studied by the method of Raman spectroscopy. The degree of graphitization was estimated by the ratio of the peak areas D (defective component) and G (graphite component). A decrease in the degree of graphitization after solvolysis was shown for both types of carbon fibers. The crystallite sizes of carbon fiber samples were determined by X-ray diffraction analysis. The results showed a decrease in the apparent thickness of Lc and the transverse size of the La crystallite for all samples after solvolysis.

PREPARATION AND LUMINESCENT PROPERTIES OF LEAD-FREE HALIDE DOUBLE PEROVSKITE MATERIALS
Authors: Xiaolong Jing , Tianchun Lang , Cherkasova Tatiana G. , Tao Han
Published: February 2025

Halide perovskite APbX3 (A = CH3NH3+, Cs+; X is a halogen ion) has been proved by scholars to be a material with great potential in photovoltaic and optoelectronic applications due to its charge transport characteristics, narrow-band emission, adjustable emission wavelength and high carrier mobility. However, due to adverse factors such as toxicity and easy decomposition of lead halide perovskite materials, its future development and research application are limited. In order to overcome the toxicity and easy decomposition of halide perovskite, this paper prepared Cs2NaBiCl6:x%Mn2+ (x = 0, 1, 3, 6, 9) by precipitation method. Na+ and Bi3+ ions are substituted two Pb2+ ions, and the lead-free halide double perovskite (Cs2NaBiCl6) matrix was prepared and doped with Mn2+. The effects of different Mn2+ doping concentrations on its luminescence properties were studied. The results showed that the prepared sample was relatively pure and there were no other hetero-phase. When the doping concentration of Mn2+ reaches 6%, the luminescence intensity is the highest. Different excitation wavelengths (340 nm, 363 nm, 380 nm) and emission wavelengths (560 nm, 582 nm, 600 nm) were used to measure the emission state and excited state of the sample, which showed that the prepared sample was the same emission source. The calculated color coordinates are (0.5288, 0.4665), belonging to the orange-yellow region. Finally, the inorganic halide double perovskite material with great development prospect was obtained.

Authors: Jia Suying , Adilbish Gelegjamts , Sharkhuu Batzusem
Published: February 2025

In the contemporary business landscape, which is characterized by the integration of digital technologies with numerous industries, the concept of value co-creation is becoming an increasingly important and creative competitive strategy. Scholars have highlighted the absence of robust arguments and theoretical guidance for organizations seeking to implement value co-creation practices with consumers. This thesis employs the theory of value co-creation as a foundational framework and a mixed-methods approach, utilizing structural equation modelling (SEM), to investigate the mechanism through which value co-creation affects enterprise performance. The findings of the research demonstrate that business model innovation acts as a mediating factor between value co-creation and enterprise performance, while internal process management exerts a moderating influence between the two. It is recommended that the findings of this research be employed to develop efficacious strategies for the implementation of value co-creation in enterprise practice management, with the objective of enhancing enterprise performance.

Published: February 2025

Aiming at the influence of consumer culture, this paper explores whether the integration of different elements into Chinese brands has an impact on consumers' global brand perception, perceived functional benefits, perceived symbolic benefits, and purchase intention, as well as the differences in the degree of impact. Based on previous studies, the paper divides the perceived symbolic benefit into three dimensions: brand reputation, unique benefit and global citizenship, and explores the mechanism of the influence of perceived globality on purchase intention. The openness of consumer culture is introduced as a moderating variable to verify whether it has a moderating effect on the overall effect of perceived globality and purchase intention. Most of the research is aimed at local promotion, so that brands can stand in a cultural perspective and infect more global consumers. In this study, the experimental method was adopted to collect data through a questionnaire and a formal experimental questionnaire. After screening, SPSS 21.0 was used for statistical analysis of valid data. The results show that: (1) Compared with local elements, Chinese local brands with global or foreign elements can make consumers perceive more global; Compared with local and foreign elements, local brands with foreign elements are more willing to buy. (2) Brand perceived globality positively influences perceived functional and symbolic benefits, and has a more significant impact on the latter's global citizenship attributes. (3) Consumer cultural openness positively moderates the impact of perceived globality on perceived functional and symbolic benefits. According to the conclusion of the research, the author provides corresponding suggestions for Chinese brands to carry out marketing in domestic and overseas markets. Finally, the limitations and future prospects of this study are pointed out.
