Published: January 2025

In exploring the precision limits of quantum metrology, the quest for a tighter Heisenberg limit in real-world environments becomes a key challenge. For this reason, in this paper, we propose a tighter Heisenberg limit for phase estimation, called the photon loss (PL)-type bound and the photon diffusion (PD)-type bound in realistic scenarios under the framework of quantum Ziv-Zakai bound (QZZB). In order to demonstrate the superiority of the proposed Heisenberg limits for phase estimation, as a comparison, we also introduce the Margolus-Levitin (ML)-type and Mandelstam-Tamm (MT)-type bounds [Phys. Rev. A 90, 043818 (2014)10.1103/PhysRevA.90.043818] based on the QZZB framework when considering the same initial states, i.e., a coherent state, a superposition state of the vacuum and general Fock states, and an even coherent state. The simulation results show that for photon-loss scenario, the PL-type bounds for all given initial states are closer to the QZZB than the ML-type and MT-type bounds, thereby exhibiting a tighter Heisenberg limit. In contrast, for the phase-diffusion scenario, when the phase diffusion strength exceeds a certain threshold, the tightness of PD-type bounds for the coherent state and superposition state can present better than that of the ML-type and MT-type bounds. Furthermore, the tighter QZZB over the QCRB can be achieved using the superposition state in photon loss or the even coherent state in phase diffusion.

Published: January 2025

Broadband polarization measurement plays a crucial role in numerous fields, spanning from fundamental physics to a wide range of practical applications. However, traditional approaches typically rely on combinations of various dispersive optical elements, requiring bulky systems and complicated time-consuming multiple procedures. Here we have achieved broadband spectropolarimetry based on single-shot images for spatial intensity distributions of polychromatic vector beams. A custom-designed diffractive optical element and a vortex retarder convert the incident polychromatic waves into structured vector beams: the former diffracts light of different wavelengths into concentric circles of different radii, while the latter codes their polarization information into intensity distributions along the azimuthal direction. The validation experiments verify our exceptional measurement accuracy (RMS errors<1%) for each Stokes component in the visible light range (400–700 nm), with good spectral (<0.8  nm) and temporal (an output rate of 100 Hz) resolutions. We have further employed our broadband polarimeter to study the mutarotation of glucose, making direct observations of temporal evolutions of chemical reactions accessible. Our work has significantly broadened the toolboxes of spectropolarimetry, which can potentially incubate various disruptive applications that depend on broadband polarization measurements.
Networks of climate obstruction: Discourses of denial and delay in US fossil energy, plastic, and agrichemical industries
Authors: Kinol Alaina , Si Yutong , Kinol John , Stephens Jennie C.
Published: January 2025

The use of fossil-derived hydrocarbons in fossil energy, plastic production, and agriculture makes these three sectors mutually reinforcing and reliant on sustained fossil fuel extraction. In this paper, we examine the ways the fossil fuel energy, plastics, and agrichemicals industries interact on social media using Twitter (renamed X as of 2023) data analysis, and we explore the implications of these interactions for policy. Content analysis of the text of tweets from the two largest US corporations and a major trade association for each sector (three discrete social media accounts for each sector) reveals coordinated messaging and identifies synergistic themes among these three sectors. Network analysis shows substantial engagement among the three sectors and identifies common external entities frequently mentioned in each sector. To understand the discursive strategies of the twitter networks of these three petrochemical derivative and fuel sectors, we propose the discourses of climate obstruction framework, adapted from and expanding on Lamb et al.’s (2020) discourses of climate delay framework. Our framework integrates both discourses of delay and discourses of denial because an integration of both were found in our analysis suggesting coordinated efforts to obstruct climate action. Our analysis suggests that discourses to deny and delay climate policy are aligned and coordinated across the three sectors to reinforce existing infrastructure and inhibit change. Exceptions in this alignment emerge for a few distinct sector-specific goals, including contrasting messages about biofuel. Despite some disparate views and different policy priorities among these three sectors, similar efforts to reinforce existing extractive petrochemical hegemony and undermine climate policy are clearly evident in each sector. These findings suggest that more research is needed to understand collaborative efforts among fossil energy, plastic, and agrichemical producers to influence climate and energy policy.
Determination of optimal gamma radiation dose for mutation breeding in ’Sabz’ fig (Ficus carica L.) cuttings based on radiosensitivity and phenotypic changes

Published: January 2025

The dried fig cv. Sabz of Iran, distinguishes out among the several fig cultivars for its unique characteristics and excellent properties. The aims to this study were 1) Carefully monitoring the resulting phenotypic changes in growth patterns, leaf morphology, shoot traits, root characteristics, and other relevant traits after irradiated with different gamma rays; 2) Investigating the LD25, 50, 75 and GR25, 50, 75 values at different gamma radiation doses for chose optimum dose. According to our results, the LD50 was 70 Gy, while the LD25 and LD75 were approximately 48 and 95 Gy, respectively. Data analysis revealed that higher doses, ranging from 50 to 90 Gy, led to a reduction in leaf area for fig hardwood cuttings compared to those exposed to lower doses of gamma irradiation (10, 20, 30, and 40 Gy). In fig cuttings, the plant height gradually decreased in line with increasing irradiation doses up to 60 Gy. Among the root traits, root number was particularly influenced by higher radiation doses. On other hand, when fig cuttings were exposed to a 40 Gy radiation dosage, the average root count dropped by 50%. However, when fig cuttings were subjected to a 90 Gy radiation dose, the average root count surged by 90.7% in comparison to the control treatment. Additionally, the GR50 values were 63 Gy for internode length, 67 Gy for leaf area and 56 Gy for plant height and aerial biomass. However, the GR50 values for root number, root volume, and root biomass were 46 Gy, 57 Gy, and 51 Gy, respectively. An analysis based on the GR25, GR50, and GR75 values indicated that plant height, aerial biomass and root biomass exhibited greater sensitivity to radioactivity in comparison to other plant portions of the fig. According to the biological responses in the ‘Sabz’ fig, 60 Gy of gamma radiation is a suitable dose for initial mutagenesis studies.

Published: January 2025

Background

To study the efficacy and safety of Polyethylene glycolated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in the prevention of neutropenia during concurrent chemoradiotherapy for nasopharyngeal carcinoma (NPC).

Methods

This is a single-center, prospective, randomized controlled study conducted from June 1, 2021, to October 31, 2022 on patients diagnosed with locally advanced NPC. Participants were divided into an experimental group and a control group. The experimental group received PEG-rhG-CSF injections post-chemotherapy cycles, whereas the control group received standard care without additional intervention. Outcomes assessed included grade 3/4 neutropenia incidence, blood cell count changes, febrile neutropenia rates, delays or interruptions in chemotherapy/radiotherapy due to hematological toxicity, oral mucositis incidents, and bone pain occurrences, comparing these between both groups.

Results

1. 88 patients with locally advanced NPC were included, the incidence of grade 3 neutropenia in the experimental group was lower than that in the control group (P = 0.026); 2. The white blood cell count and neutrophil count in D7, D10, D14, and D21 in the experimental group were higher than those in the control group (P<0.01); 3. The rate of delayed chemotherapy in the experimental group was lower than that in the control group (2.3% vs. 29.5%), P = 0.001; the rate of interruption of radiotherapy in the experimental group was lower than that in the control group (2.3% vs.27.3%), P = 0.003; 4. The incidence of bone pain in the experimental group was 34.1%, of which most were mild bone pain, and no severe bone pain occurred. The leukocyte and neutrophil counts of the patients in the bone pain group were significantly higher than those of the patients in the no bone pain group, P(WBC) = 0.001, P(ANC) = 0.002.

Conclusions

The preventive use of PEG-rhG-CSF decreases the incidence of neutropenia in patients undergoing concurrent chemoradiotherapy for NPC, thereby reducing rates of chemotherapy delays and radiotherapy interruptions, with mild adverse reactions that are tolerable by patients.
N-acetyl-L-cysteine and lauric acid; effective antioxidant and antimicrobial feed additives for juvenile Pacific white shrimp (Litopenaeus vannamei) cultured at high stocking density
Authors: Fatima Shafaq
Published: January 2025

Present study aimed at improving the immune and antioxidant response of Pacific white shrimp (Litopenaeus vannamei) cultured at high stocking density fed with 0.2% supplementation of lauric acid (LA) and N-acetyl-L-cysteine (NAC). Shrimp (initial average weight = 0.65 g; n = 270) were grown at low stocking density (LSD) (n = 10/0.80 ft3 per replicate) and high stocking density (HSD) (n = 20/0.80 ft3 per replicate). They were randomly distributed into five groups (T1: negative control at LSD, T2: positive control at HSD, T3: at HSD and fed with LA supplement diet, T4: at HSD and fed with NAC supplemented diet, T5: at HSD and fed with combination of LA and NAC). All these five treatments were studied in triplicates and study continued for eight weeks. Better growth and higher levels of glucose, total protein, total hemocyte count and phagocytic index were observed in shrimp fed with NAC and LA supplemented diets. Observed survival rate and feed conversion ratio in all treatments was 75–89% and < 0.82, respectively. All parameters indicating stress were observed to be higher in T1 as compared to T2. Improved expression of superoxide dismutase and glutathione peroxidase and lower levels of malondialdehyde genes in T3, T4 and T5 showed that supplementation with these nutraceuticals can improve antioxidant response at high stocking density. A parallel increase was observed in the profiles of prophenoloxidase and lysozyme, underscoring the immune-boosting effects of both NAC and LA. This finding was further supported by higher expression of innate immune signaling pathway-related gene, toll like receptor-2 in T3, T4 and T5. In conclusion, NAC and LA, can possibly improve the resistance of white pacific shrimp against oxidative stress and pathogens when cultured in intensive production system.

Rapid population expansion has made food security a global concern for humanity, necessitating a sustainable assessment of natural resources. Well evaluated and managed soil is one of the most significant resources that can assist close the gap between supply and demand for food to attain food security. A precise assessment of land productivity (LP) is essential for sustainable land use management. The primary aim of this research is to predict the land productivity index (LPI) for certain locations on Egypt’s northwest coast under current conditions using soil quality indicators (SQIs). Additionally, the study proposed relevant management actions to boost land productivity in the future. To achieve this aim, a spatial model was created to assess LPI for some areas in the north western coast of Egypt. LP equation was used to estimate current land productivity index (CLPI) and potential land productivity index (PLPI). Results found that the study area mainly located under two classes of CLPI, e.g., average (class ⅡⅠ) represents an area of 13322.63 ha (67.55%) and good grade (class Ⅱ) covers an area of 4339.78 ha (22%). PLPI grades were good (II) and average (III) with an area of 16192.54 ha (82.10%) and 1903.23 ha (9.65%), respectively. The finding showed that more than 60% of the studied area was converted from poor and average class to good class after applying the proposed solutions of soil improvement. The methodology presented here can easily be replicated under similar circumstances in arid zones, allowing local governments and decision-makers to utilize the quantitative results obtained to ensure sustainable development.
Effects of different tennis racket string tension on forehand stroke effect and racket dynamic impact
Authors: Zhao Guohui , Li Chen , Liu Ye
Published: January 2025

This study investigates the effect of varying tennis racket string tension on stroke effect and the dynamic response of the racket. Using the YSV dynamic acceleration signal acquisition system and a portable radar speed gun collect data on racket acceleration, stress-strain signals, and ball speed from 15 male athletes. Stroke accuracy and depth were assessed according to the International Tennis Number. The recorded stroke speeds were 108.87±13.57 km/h, 111.83±16.34 km/h, and 107.76±12.53 km/h for the low, medium, and high tension, respectively. A significantly higher ball speed was observed at 54lbs compared to both 48lbs and 60lbs (P <0.05). Control scores were 4.90±0.61,5.46±0.84, and 4.64±0.69 for the respective tensions. The control at 54lbs was significantly higher than at 60lbs (P<0.05). Deformation measurements were 18.53±4.90με, 16.31±4.42με, and 20.90±3.53με, with significantly lower deformation at 54lbs compared to 60lbs (P<0.05). The impact forces recorded were 381.81±48.51m/s2, 380.53±50.47m/s2, and 380.04±53.70m/s2, with no significant effect of string tension on impact force. Racket vibration frequencies were 44.14±0.48Hz, 44.08±0.35Hz, and 44.14±0.25Hz, with no significant difference among three string tensions. Rackets with three string tensions showed significantly higher vibration frequencies during the collision phase compared to before or after (P<0.01). In conclusion, string tension affect the stroke effect, racket strung at medium tension can optimize stroke effect while got milder dynamic impact, suggesting that racket strung at medium tension is recommended for tennis enthusiasts to enhance stroke performance and to decrease the risk of resonance damage in the forearm soft tissues.
Plutarco. Vidas Paralelas. Licurgo e Numa: Introdução, notas e comentário
Authors: Rodrigues Ália Rosa C.
Published: January 2025

Traduzido pela primeira vez para português a partir do grego antigo, as Vidas Paralelas de Licurgo e Numa de Plutarco é um texto fundamental tanto nos estudos clássicos como na história do pensamento político ocidental. Embora envoltas em mito, Licurgo e Numa tiveram um impacto significativo na tradição legal e política antigas que perdura até aos dias de hoje. A primeira, a biografia de Licurgo, teve uma história de recepção controversa, tendo sido frequentemente citada em manuais de academias militares prussianas e nas escolas nazis de elite, onde ele era visto como um modelo de disciplina e obediência.
Já a segunda Vida, a biografia de Numa, o segundo rei de Roma, é uma das poucas fontes para a fundação das instituições religiosas da cidade. Sendo ele próprio um Sabino e caracterizado como pacificista, a figura de Numa ajudou a construir a percepção de Roma como uma força estável e multi-étnica no mundo antigo.

Published: January 2025

This study has established a highly practical classification system to develop measures for reducing chemical accidents. Taxonomy for chemical accident was improved by investigating accident classification statuses domestically and internationally. And analyzed cases of chemical accidents that occurred domestically for validation. To analyze a single incident from multiple perspectives, it was categorized into 9 major classifications: type, cause, place, damage, date, substance, accident facility, work detail, and violations. The 9 items were classified into 64 categories, which were further subdivided into 60 sub-classifications to enable detailed identification of causes. This study is expected to provide important foundations for institutional improvements such as strengthening regulations on chemical handling facilities and management, as well as formulating preventice measures for chemical accidents.

Published: January 2025

Multiple endocrine neoplasia syndrome type 4 (MEN-4) is a rare autosomal dominant disease caused by mutation in the CDKN1B gene encoding the cell cycle regulator p27. Currently, a small number of clinical cases of patients with this pathology are known. Patterns of genotype-phenotype correlations in patients with CDKN1B mutations remains controversial and requires additional clarification. MEN-4 affects the same organs as MEN-1, however, the age of manifestation and the course of the disease may differ. We present the clinical case of a patient with MEN-4 with a new frame shift mutation in the CDKN1B gene caused PHPT with multiple parathyroid gland pathology and prolactin-secreting pituitary microadenoma. The first component of the disease diagnosed at the age of 37 was prolactinoma. Later, a visceral form of PHPT with isolated kidney complication was revealed. The patient has got the necessary treatment of the identified pathologies with satisfactory results. During a comprehensive examination, the involvement of other endocrine organs was not revealed. The limited number of case reports of patients with mutations in the CDKN1B gene currently does not allow us to determine the patterns of this syndrome’s course, and therefore a detailed description of the disease’s clinical presentation in a patient with a newly identified mutation makes a significant contribution to the study of this pathology.
Economic Recovery Strategy: The Role of MSMEs Credit Access and Optimization of Regional Fiscal Stimulus in Islamic Economics Framework
Authors: Prajasari Anniza Citra , Wijayanti Dwi Marlina
Published: January 2025

This paper aims to analyze the determinants of economic recovery in North Sumatra using district-based panel data from 2020-2022 using the Random Effect Model. Several variables derived from the implications of fiscal and monetary policies such as MSME credit access, inflation, the effectiveness of income spending, poverty, unemployment rate, and human development index were used to analyze economic recovery as proxied by GRDP per capita. Our findings indicated that the position of MSMEs' credit and relative poverty have a significant positive effect on economic recovery in North Sumatra. Conversely, the unemployment rate and human development index have a significant negative effect on economic recovery in North Sumatra. Inflation and the effectiveness of income spending have an insignificant effect on economic recovery in North Sumatra. These findings recommend that the government and the central bank should support increased access to MSME credit in terms of regulations, the availability of bank financial institutions, and allocations. In addition, it is crucial to maintain the effectiveness and increase indirect budget allocations for social fund posts that can be integrated with Islamic Social Funds such as Zakat, Infaq, and Shadaqah to address poverty and unemployment challenges to improve the community’s quality of life and accelerate economic recovery in North Sumatra.
Religious Tolerance In Tunisia: Divergent Perspectives Of Thâalbi And Ibn Achour
Authors: Elmuna Labib , Khafidin Amine , Fathurrahman Luthfi
Published: January 2025

Studi ini mengeksplorasi pandangan Muhammad Tahir ibn Achour dan Abdelaziz Thâalbi tentang toleransi agama dalam Islam, menganalisis bagaimana pandangan mereka dibentuk oleh konteks sosial-politik dan kerangka intelektual masing-masing. Ibn Achour, sebagai seorang sarjana dan tradisionalis, menekankan toleransi agama sebagai nilai inti Islam, dengan fokus pada penafsiran teks dan pembaruan intelektual untuk mendorong harmoni antaragama. Pendekatannya sejalan dengan tafsir Islam klasik dan konsep Mawashid Syariah, yang mengusung pemahaman yang lebih mendalam terhadap teks-teks agama dalam menghadapi tantangan modern. Sebaliknya, Thâalbi memandang toleransi melalui lensa agenda nasionalisnya, menjadikannya alat untuk memperkuat solidaritas melawan kolonialisme Prancis. Ia menekankan prinsip etika Islam terhadap non-Muslim, namun dalam kerangka politik yang bertujuan untuk kesatuan nasional dan perlawanan terhadap penindasan kolonial. Studi ini menggunakan metode kualitatif komparatif, menganalisis sumber-sumber primer dan sekunder, termasuk karya-karya kedua pemikir dan konteks sejarah mereka. Temuan studi menunjukkan bahwa pendekatan Ibn Achour memberikan kedalaman teologis dan filosofis dalam diskursus toleransi, sementara penerapan toleransi oleh Thâalbi memiliki tujuan politis. Analisis komparatif ini tidak hanya memperdalam pemahaman kita tentang bagaimana kedua pemikir ini menangani tantangan koeksistensi dan keberagaman budaya pada masa mereka, tetapi juga memberikan kontribusi pada perdebatan filosofis yang lebih luas tentang toleransi baik dalam konteks Islam maupun konteks modern.

Authors: Wibowo Rizki Agung , Nisa Khoirin , Samosir Amril
Published: January 2025

Background: Open-access is free online access to articles, journal, conferences proceedings, book series and trade journal which provides unrestricted and permit the users to read, download, print, copy and link to the articles. Many articles that discuss the journal metrics using basic statistical methods to discribe the journal.Objective: This research groups journals based on numerical quality measures, identifying quality characteristics for each group. The findings provide a reference for researchers to select suitable journals and for journal owners to improve journal quality.Methods: There is another method to describe the open-access journal by grouping it into groups with the homogeneous characteristics based on five types of numerical quality measure that are analyzed simultaneously, namely cluster analysis. By using cluster analysis, the article’s owner can determine which journals he can choose to publish it in according to the desired journal quality. Based in the result, 5146 open-access journals can be divided into four clusters by using CLARA algorithm. Cluster 1, 2 and 3 have high characteristics in all numerical quality measure and cluster 4 have low characteristics in all numerical quality measure. So that researchers can choose journals in clusters 1, 2, and 3 as a place to publish their research by adjusting the journal's scope.Results: This study demonstrates that the CLARA algorithm successfully grouped 5146 open-access journals indexed by SCOPUS into four clusters based on quality characteristics. Cluster 1 consists of 39 journals with high values across all quality variables, Cluster 2 includes 50 journals with similarly high values, Cluster 3 contains 430 journals with comparable characteristics, and Cluster 4, comprising 4627 journals, exhibits low values in all quality variables. Furthermore, the majority of journals (89.914%) have numerical quality measures below the average.Conclusion: This study concludes that journals in Clusters 1, 2, and 3 can be recommended as suitable options for researchers to publish their work, considering the relevance of the journal's scope. Additionally, these findings can serve as a reference for journal owners to improve the quality of their journals to meet higher standards.

One of the models in survival analysis is the Cox proportional hazards model. This method ignores assumptions regarding the distribution of survival times studied. If there are indications of multicollinearity in data handling, one way that can be done is to use PCA (Principal Component Analysis). PCA-Cox regression is a combination of survival analysis and PCA which can be an alternative in analyzing multicollinearity survival data. The large number of cases of bad credit means that customers must be careful in providing credit to prospective customers. Character, capacity, capital and collateral variables are thought to influence the length of time customers pay house ownership loans at the bank. The data used is secondary data (n=100) regarding the assessment of character variables, capacity, capital and collateral, credit collectibility, and time to pay customer house ownership loans at the bank. The results of the analysis using PCA-Cox regression show that the variables character, capacity, capital and collateral have a significant effect on the length of house ownership loan payment time for Bank X customers. The originality of this research is the use of the PCA-Cox regression integration model in bank credit risk analysis.
15. listopad 1939: Zprávy německé provenience
Authors: Šimůnek Michal V.
Published: January 2025

The mass demonstrations following the funeral of Jan Opletal, a student at the Faculty of Medicine of Charles University deadly wounded by the shot on 28 October 1939, in the centre of Prague on 15 November 1939, have remained rather in the shade of the brutal German aftermath two days later, on 17 November 1939. It has to be kept in mind that they had been the most overt Czech protest against the German occupation before May 1945. Their course was recorded contemporarily in both Czech and German official reports, which have been taken into account in the post-war historical literary production to certain degree. Those reports, unedited and unpublished so far, served on the German part as a basis for the key political decisions of criminal nature. Seven of such reports could be found and are presented in this edition. Among others, the report from the head of the Reich Main Security Office (Reichssicherheitshauptamt) R. Heydrich to the head of the Reich Chancellery (Reichskanzlei) H. H. Lammers from 15 November 1939 is published here for the very first time.

Groundwater well fields in ice-margin valley aquifers - is it easy to protect them, or not? An overview of hydrogeological and legal aspects of determining wellhead protection zones
Authors: Matusiak Magdalena , Górski Józef , Dragon Krzysztof , Kruć-Fijałkowska Roksana
Published: January 2025

This paper discusses principles for delineating wellhead protection zones (WHPZ) of groundwater well fields in ice-margin valleys. A distinctive feature of such well fields is that, apart from the often geogenically contaminated water of ice-margin valleys, they are largely supplied with high-quality water from intertill aquifers of neighbouring uplands. However, much of this inflow can be intercepted by wells for agriculture that are increasingly being constructed in the capture zones of existing municipal well fields, thus posing a threat to the quality of water for the public. This problem has been investigated using the example of a municipal well in Wroniawy (Poland) by analysing changes in the recharge components of this well field with a groundwater flow model. The results indicate that the commissioning of agricultural abstractions in the capture zone of this well field reduces inflow from intertill aquifers (8.5 per cent) and precipitation recharge (3.3 per cent), following a change in the extent of the capture zone. The loss of these qualitative recharge components is substituted by an increase in poor-quality water, i.e., surface water (7.3 per cent) and geogenically contaminated water from the ice-margin valley centre (3.8 per cent). Protecting well fields in such locations from adverse water quality changes requires the implementation of quantitative shielding of best-quality water, calling for WHPZ to cover the entire capture zone regardless of water flow timing, which is not provided for in Polish legislation. Costs and constraints of implementing such a WHPZ can be reduced by dividing it into sectors that differ in the scope of limitations, with the only quantitative protection applied to the outermost, medium- and low-vulnerable parts of the capture zone.
Depositional palaeoenvironments in a tide-influenced delta plain with amphibian and Cycadophyta remains - the Triassic Zarzaitine Formation (Algerian eastern Sahara)
Authors: Mazrou S. , Lasnami Y. , Amer J. , Boutaleb A.
Published: January 2025

In the region of In Amenas (south-eastern Algeria) Triassic deposits crop out, on top of Palaeozoic rocks under an angular unconformity. A study of their sedimentological and palaeoenvironmental characteristics has revealed a sandy-clay unit with vertebrate remains, tree trunks and ichnofossils of Middle-Late Triassic age. This so-called Zarzaitine Formation, which reflects deposition in a deltaic environment, shows three facies associations. The first defines an upper and shallow intertidal mixed flat zone with in-situ temnospondyl capitosauroid remains, associated with Skolithos ichnofacies, while the second one defines a lower intertidal delta plain zone, composed of sandstone, distributary channels and muddy interdistributary areas,which record daily tidal rhythmites and monthly tidal bundles. The third, and last, facies association represents an upper delta plain of the supratidal zone, characterised by coarse sandstone deposits of braided rivers and a Cycadophyta palaeosol. Previous work, which led to considering these Triassic deposits as a series composed of four formations, deposited in a braided rivers environment, whose lower floodplains constituted ecological niche for a temnospondyl fauna, under hot and dry climatic conditions and plants belonging to this same formation, for mushrooms and algae, will also be considered.

Promowanie kultury antycznej poprzez grywalizację na przykładzie cyklu książek o Harrym Potterze autorstwa Joanne Kathleen Rowling
Authors: Czachor Miriam
Published: January 2025

Spotkanie z kulturą antyczną ma miejsce już w szkole podstawowej – uczniowie poznają wówczas wybrane fragmenty mitologii oraz elementy filozofii greckiej, aby odkryć grecko-rzymski rodowód swojej tożsamości. Fragmentaryczny zakres przedstawionej wiedzy oraz sposób jej przekazywania nie zawsze jednak wywołuje zainteresowanie. Być może więc problemem nie jest niechęć do poznawania kultury antycznej, ale sposób jej przybliżania. Dlatego autorka proponuje wykorzystanie edukacyjnych możliwości,  akie daje grywalizacja, oraz tekstu kultury popularnej (serii książek o Harrym Potterze) jako innowacyjnego dydaktycznie rozwiązania zachęcającego do zainteresowania się tą kulturą. Artykuł został napisany na podstawie fragmentów pracy dyplomowej oraz powstałego w jej ramach autorskiego projektu grywalizacji.
Kompetencja interkulturowa nauczycieli pracujących z dziećmi z doświadczeniem migracji: wnioski z projektu „INNA SZKOŁA”
Authors: Pamuła-Behrens Małgorzata , Wrona Justyna
Published: January 2025

Artykuł omawia kompetencje nauczycieli pracujących z uczniami migrantami (na podstawie badań realizowanych w ramach projektu Małopolski model wsparcia nauczycieli pracujących z uczniami z doświadczeniem migracji „INNA SZKOŁA” 2021). Przed kursem szkoleniowym i po jego ukończeniu nauczyciele oceniali swoje umiejętności w ankietach, skupiając się na samoocenie kompetencji interkulturowej, przygotowaniu do pracy z uczniami z doświadczeniem migracji i rozwijaniu świadomości potrzeb tych uczniów. Choć nauczyciele początkowo wątpili w swoje przygotowanie i sens rozwoju w tym aspekcie, udział w projekcie zmniejszył te obawy i wzbogacił ich wiedzę o specyficznych potrzebach dzieci-migrantów.

Authors: Kosmalska Weronika , Rybka Małgorzata
Published: January 2025

Artykuł dotyczy tematu podejmowania pracy i życia zawodowego w procesie nauczania dorosłego ucznia języka i kultury polskiej jako obcych. Dzięki prezentowanym podczas lektoratów materiałom dydaktycznym, m.in. podręcznikom i ćwiczeniom, uczący się re/konstruują obrazy polskiego rynku pracy, a także Polaka i Polki zatrudnionych w różnych zawodach, często łączących obowiązki zawodowe z opieką nad dziećmi. Obcokrajowcy uczą się, jak może przebiegać rozmowa o pracę, jak powinni napisać swoje CV i list motywacyjny. Dowiadują się również, że sposób nawiązania stosunku pracy może być różny. Artykuł przynosi propozycję dodatkowych ćwiczeń, opartych na autentycznych tekstach prawnych, wprowadzających specjalistyczne słownictwo i pokazujących, czym różni się umowa o pracę od umowy-zlecenia i umowy o dzieło. Analiza poszczególnych typów umów związanych z zatrudnieniem powinna bowiem pozwolić uczącym się języka polskiego jako obcego na sprawniejsze funkcjonowanie na polskim rynku pracy.
The Effect of an Augmentative and Alternative Communication (AAC) Training Program on Perception upon AAC and AAC Teaching Efficacy among Myanmar Special Education Personnel
Authors:   Korean Society of Augmentative and Alternative Communication, Tu Hnine Tu Hnine , Park Eunhye
Published: January 2025

Providing education to children with disabilities in Myanmar faces significant challenges, primarily due to limited resources and a shortage of trained professionals. The special education system is underdeveloped, making it difficult for children with complex communication needs (CCN) to engage in educational and social interactions. Teachers often lack the confidence and knowledge required to implement educational interventions such as Augmentative and Alternative Communication (AAC). This study evaluated the impact of AAC training on the perceptions and teaching efficacy of 19 staff members at an NGO-based special education center in City A, Myanmar. Participants included special education teachers, physiotherapists, paraprofessionals, and administrators working with students who have communication challenges. Using a one-group pretest-posttest design, the study assessed changes in participants’ perceptions of AAC and their teaching efficacy, with data analyzed through dependent sample t-tests. Results indicated a significant improvement in participants’ knowledge of AAC following the training program, which also notably enhanced their confidence in teaching communication. These findings underscore the need for further AAC training in Myanmar’s special education sector.
Establishment and range expansion of invasive Cactoblastis cactorum (Lepidoptera: Pyralidae: Phycitinae) in Texas
Authors: Morrison Colin R. , Plowes Robert M. , Springer Laura E. , Sanchez-Peña Sergio , Gilbert Lawrence E.
Published: January 2025

Invasive species are a leading cause of global biodiversity decline. Larvae of the cactus moth Cactoblastis cactorum Berg (Lepidoptera: Pyralidae: Phycitinae) consume prickly pear cactus species (Opuntia; Cactaceae) in its native South American range. High host specificity made C. cactorum an appropriate biological control agent of Opuntia species, which have become invasive weeds around the world. This biological control program was successful. Ironically, the success of cactus weed biological control facilitated a series of events which led to C. cactorum invasion of North America where Opuntia diversity is tremendous. In 2017, C. cactorum established along the southeast Texas coast. In 2020, we began monitoring C. cactorum dispersal towards south and south-west Texas with cactus moth pheromone traps. Our objectives were to document the extent of the invasion and calculate dispersal rates towards commercial Opuntia-growing regions in Mexico. There are four overlapping moth flight peaks in Texas. Between 2017 and 2022, the C. cactorum populations invaded over 27,000 km2 in south-east and south-central Texas at a dispersal rate up to 47 km year. Since 2022, this dispersal rate slowed as the moth invasion front came into contact with the Tamaulipan thornscrub region of south Texas where Opuntia density is high and native cactus moth species are attacked by a diverse assemblage of parasitoids. We present data on the density of native cactus moth species in Texas which shows that their density increases west and south-west of the area currently occupied by C. cactorum. These data suggest that apparent competition may be occuring between C. cactorum and native cactus moth species via shared parasitoids. This hypothesis is not mutually exclusive of other biological barriers that may contribute to explaining why the Texas C. cactorum dispersal rate has slowed significantly. We conclude with a discussion about how to leverage these data to support future deployment of C. cactorum biological control agents in Texas.
Exploring visible light communication for real-time indoor metaverse connectivity
Authors: Singh Anil Kumar , Pandey Rohitashwa
Published: January 2025

This paper investigates the use of Visible Light Communication (VLC) technology for indoor communication systems within the context of Metaverse applications. As immersive virtual environments continue to expand, the demand for high-speed, low-latency, and energy-efficient communication technologies becomes crucial. VLC, leveraging visible light from LED lamps to transmit data, presents a promising alternative to conventional radio frequency-based communication methods. In this case study, we explore the potential of VLC to support the real-time, interactive, and data-intensive requirements of indoor Metaverse applications, such as virtual reality (VR) gaming, remote collaboration, and augmented reality (AR) experiences. The study includes the design and implementation of a VLC-based communication system, analyzing its performance in terms of data rate, and BER in a typical indoor Metaverse scenario. Simulation results and experimental findings demonstrate that VLC can provide robust, high-bandwidth communication with lower interference, positioning it as a viable solution for future Metaverse infrastructure.
