IntroductionThe literature on leadership has evolved in accordance with changing global expectations over time and the significance of new leadership approaches which are based on environmental sustainability has increased day by day. Green transformational leaders, one of the results of this evolution, are different from other leadership approaches in terms of their role in motivating employees and increasing their environmental awareness by integrating their environmental sensitivities into the organizational culture.MethodsThis study, which aims to determine the mediating role of job satisfaction in the effect of green transformational leadership on intention to leave, was conducted with 391 people working in 4 and 5 star hotels in Antalya region. Data obtained by convenience sampling method was examined with Smart-PLS program. The study was shaped on the axis of structural equation modeling.ResultsThe findings showed that green transformational leadership has a negative effect on intention to leave and job satisfaction plays a mediating role in this relationship. In addition, green transformational leaders were found to increase employees’ job satisfaction, strengthen their commitment to the organization and reduce intention to leave.DiscussionThe study shows that green transformational leadership has an effective structure not only in terms of green and environmental concepts but also in terms of organizational behavior. According to the Social Exchange Theory, green transformational leadership is thought to shape the job satisfaction of employees by interacting with them in accordance with moral and organizational norms.

IntroductionFood pantry managers play a key role in determining the food environment of the pantry, which can influence their clients’ dietary composition. However, their impact on pantry food environments remains understudied. We sought to understand food pantry managers’ nutrition knowledge, beliefs, and behaviors (KBBs) in this study.MethodsWe surveyed 47 Alabama food pantry managers’ nutrition KBBs from November 2022 to November 2023. Validated and previously published tools used include the Consumer Nutrition Knowledge Scale, a diet beliefs scale, and a dietary-related consumer behavior questionnaire.ResultsThe majority of managers were college-educated (54%), white (74%), and female (74%), with a mean age of 60 ± 13 years and an average of 7 ± 5.5 years of experience in managing food pantries. Managers reported positive nutrition beliefs and behaviors but scored lower on objective nutrition knowledge. Exploratory analyses indicated moderate to very strong associations between KBBs, pantry characteristics, and neighborhood characteristics.ConclusionNutrition education for pantry managers, along with improved pantry infrastructural support, could play a key role in improving the healthfulness of the food provided.

Published: February 2025

The Human Leukocyte Antigen (HLA) system forms the central part of the immune system and is crucial in the recognition and elimination of “non-self” antigens. While this role of the HLA system is essential in the effective defense of the organism against pathogens, it is undesirable in organ and tissue transplantation because it enables the recognition of mismatched HLA molecules of the donor as being foreign and stimulates the graft rejection reaction. Organ transplantation involves the introduction of antigens that are more or less mismatched to the recipient; therefore, in order to achieve the best possible match in the HLA system between the recipient and the donor, a whole series of immunogenetic tests is performed, including crossmatching (XM). If performed before kidney transplantation, it represents the final in vitro test to rule out the presence of donor-specific antibodies, which may cause graft rejection and which may not have been detected by earlier serum screening. The beginning of XM was marked by the complement-dependent cytotoxicity (CDC) method developed by Terasaki and colleagues in 1964. Later, as a result of advances in technology and the need for methods that overcome the limitations of CDC, flow cytometry and Luminex XM assays were developed. The introduction of solid-phase technology brought a new dimension to the detection of low-level HLA antibodies and the determination of their specificities, which enabled the development and implementation of the virtual XM test (vXM). It is an in silico test that assesses the immunological match between the recipient and the organ donor based on the analysis of the specificity of the antibodies present in the recipient’s serum and the HLA typing of the organ donor. Each method has its own advantages and limitations, which are described below and need to be taken into account, considering their significant impact on clinical application in kidney transplantation.

The objectives of the study were to design, synthesize, and evaluate the antibacterial activity of a series of novel aminoguanidine-indole derivatives. Thirty-seven new compounds were effectively synthesized through nucleophilic substitution reaction and guanidinylation reaction. Chemical structures of all the desired compounds were identified by NMR and HR-MS spectroscopy. Most of the synthesized compounds showed significant antibacterial activity against ESKAPE pathogens and clinical resistant Klebsiella pneumoniae (K. pneumoniae) isolates. K. pneumoniae is an important opportunistic pathogen that often threatens the health of immunocompromised people such as the elderly, children, and ICU patients. The most active compound 4P showed rapid bactericidal activity against resistant K. pneumoniae 2108 with MIC and MBC values that were 4 and 8 µg/mL, respectively. The hemolytic activity of 4P was low, with an HC50 value of 123.6 µg/mL. Compound 4P induced the depolarization of the bacterial membrane and disrupted bacterial membrane integrity and was not prone to antibiotic resistance. The dihydrofolate reductase (DHFR) activity was also notably inhibited by 4P in vitro. Molecular docking revealed that the aminoguanidine moiety and indole structure of 4P played an important role in binding to the target site of the K. pneumoniae dihydrofolate reductase (DHFR) receptor. In the mouse pneumonia model caused by K. pneumoniae, 4P improved the survival rate of mice, reduced bacterial loads, and alleviated tissues’ pathological injuries at a dosage of 4 mg/kg. Therefore, compound 4P may be a promising lead compound or drug candidate for antibacterial purposes against K. pneumoniae.

Published: February 2025

In this paper, an adaptive frequency-domain block equalizer (FDBE) implementing the adaptive moment estimation (Adam) algorithm is proposed for mode-division multiplexing (MDM) optical fiber communication systems. By packing all frequency components into frequency-dependent blocks of a specified size B, we define an adaptive equalization matrix to simultaneously compensate for multiple frequency components at each block, which is computed iteratively using the Adam, recursive least squares (RLS) and least mean squares (LMS) algorithms. Simulations show that the proposed FDBE using the Adam algorithm outperforms those using the LMS and RLS algorithms in terms of adaptation speed and symbol error rate (SER) performance. The FDBE using the Adam algorithm with B=1 has the fastest adaption time, requiring about ntr=100 and ntr=900 less training blocks than the RLS algorithm at the SER of 3.8×10−3 for the accumulated mode-dependent loss (MDL) of ξ=1 dB and ξ=5 dB, respectively. The Adam algorithm with B=16 and B=8 has 0.4 dB and 0.3 dB SNR better than the RLS algorithm with B=4 for MDL and ξ=1 dB and ξ=55 dB, respectively.

Published: February 2025

O trauma perfurante toracoabdominal ocorre entre a linha mamária superiormente, e inferiormente até o 8º espaço intercostal¹. Com uma mortalidade de até 71%², essas lesões possuem uma importância epidemiológica, sobretudo em países como o Brasil, e envolve acometimentos de órgãos nobres, como o coração e vasos menos acessíveis com potencial de sangramentos volumosos. Os objetivos desta revisão sistemática sobre traumas perfurantes na região toracoabdominal, envolvem reunir dados da literatura sobre as lesões penetrantes na região toracoabdominal; observar os fundamentos científicos consagrados e as atualizações sobre o assunto e destacar as experiências de sucesso no diagnóstico das lesões e manejo do trauma perfurante toracoabdominal. Foram utilizados os descritores nos bancos “PubMed” e "Embase": "trauma ou lesion", 'penetrating injury' ou 'stab wound' " e “thoracoabdominal". Critérios de inclusão: (1) estudos observacionais ou randomizados; (2) pacientes com lesão penetrante em região toracoabdominal; (3) artigos ou resumos disponíveis. Nenhuma restrição de tempo ou idioma foi aplicada. Identificamos 152 artigos e incluímos 75 estudos publicados entre 1980 e 2020. Dois artigos²³ destacaram uma maior ocorrência de trauma toracoabdominal nos fins de semana (75%) e outros dois demonstraram uma associação ao uso de entorpecentes, apresentando um percentual de até 26,5%. Em relação ao sequenciamento inicial, a maior taxa de indicação de laparotomia ou toracotomia, devido à instabilidade hemodinâmica foi de 37% dos pacientes¹. Para os pacientes mais estáveis, recursos indiretos ou menos invasivos demonstraram percentuais acima de 65% de acurácia diagnóstica (gráfico 1). Lesões de órgãos sólidos, de vísceras ocas e diafragmáticas, hemotórax, pneumotórax, pneumomediastino, tamponamento cardíaco, também indicaram algum tipo de intervenção. Ademais, choque hemorrágico, sepse, síndrome do desconforto respiratório agudo, foram algumas complicações associadas à mortalidade. Os estudos foram heterogêneos, trazendo diferentes aspectos diagnósticos e terapêuticos importantes para indicar tratamento cirúrgico ou conservador. Casos graves com indicação cirúrgica e evolução mais aguda, ainda são um desafio, pois há dificuldade na decisão de qual cavidade abordar primeiro e nesse sentido, estudos futuros podem favorecer a otimização do atendimento, esclarecendo essas situações.

Abstract
Flexible piezoelectric films have recently attracted attention for energy and nanoelectronic applications owing to their unique properties. One of the most widely used materials for these films is polyvinylidene fluoride. However, with increasing restrictions on the use of perfluoroalkyl and polyfluoroalkyl substance (PFAS), the development of piezoelectric films using PFAS-free materials has become crucial. Herein, we fabricated PFAS-free and lead-free flexible piezoelectric films by combining nonpiezoelectric polyimide resin (PI) with piezoelectric K0.5Na0.5NbO3 (KNN) ceramics. The piezoelectric coefficient d
33 was 30 pC/N at a KNN volume ratio of 55%. The addition of conductive fibers (CF) to the KNN-PI two-phase composite, d
33 increased to 51 pC/N. By further increasing the KNN volume ratio to 80.7%, the KNN-PI-CF three-phase composite piezoelectric films exhibited d
33 of 72 pC/N. The present method is useful for developing PFAS-free and lead-free piezoelectric films, thereby expanding the applicability of flexible piezoelectric films across a range of applications.

Published: February 2025

Understanding the impact of time, season, and loop on diurnal mammal sightings is crucial for informing effective wildlife management strategies to optimize tourist experiences. This study, therefore documented the effect of time, season and loops on the sighting of diurnal mammal species during drive safari at Mole National Park (MNP). The variables (time, season and loops) were investigated to disclose their influence on sightings. Day drive safari was used as a study method for observation and counting the animals for 1 hour minimum and a maximum of 4 hours; questionnaires were also used to solicit information on tourists' preference for diurnal mammal species to sight. The data gathered was analyzed using R version 4.3.1. A one-way ANOVA function in the car package was used to determine significant differences between variables. Seventeen diurnal mammal species were sighted in the loops of MNP. The season had no significant effects on sighting diurnal mammals in most loops except in the Burugbani and Zaina loops. Time of day had no significant influence on the sighting of diurnal mammals, but loops had a significant effect. Kobs were the most abundantly sighted diurnal mammal species in all the loops. Grey Duiker and Hartebeest were sighted only at the Burugbani and Asibey loops, respectively. Roan Antelopes were sighted at both the Asibey and Burugbani loops. Diurnal mammal abundance was highest in the Asibey loop, whereas the Zaina loop recorded the least. The African Savanna Elephant was the most expected diurnal mammal species to be sighted among tourists. In conclusion, MNP is a refuge for several diurnal mammal species that tourists can see during drive safaris. Management of Mole National Park should consider adjusting safari routes and times to coincide with peak animal activity periods, as identified in the study. This is essential in enhancing visitor’s experience. We further recommend minimising the frequency and timing of loop visits to reduce disturbance to animals and maximize sighting opportunities.
starkiller: Subtracting Stars and Other Sources from IFU Spectroscopic Data Through Forward Modeling
Authors: Ridden-Harper Ryan , Bannister Michele T. , Deam Sophie E. , Nordlander Thomas 
Published: February 2025

Abstract
We present starkiller, an open-source Python package for forward-modeling flux retrieval from integral field unit (IFU) spectrograph data cubes. starkiller simultaneously provides stellar spectral classification, relative velocity, and line-of-sight extinction for all sources in a catalog, alongside a source-subtracted data cube. It performs synthetic difference imaging by simulating all catalog sources in the field of view, using the catalog for positions and fluxes to scale stellar models, independent of the data cube. This differencing method is particularly powerful for subtracting both point sources and trailed or even streaked sources from extended astronomical objects. We demonstrate starkiller's effectiveness in improving observations of extended sources in dense stellar fields for Very Large Telescope (VLT)/Multi Unit Spectroscopic Explorer (MUSE) observations of comets, asteroids, and nebulae. We also show that starkiller can treat satellite-impacted VLT/MUSE observations. The package could be applied to tasks as varied as dust extinction in clusters and stellar variability; the stellar modeling using Gaia fluxes is provided as a standalone function. The techniques can be expanded to imagers and to other IFUs.
Hunting for Candidates of Changing-look Blazars Using Mclust Clustering Analysis
Authors: Kang Shi-Ju , Ren Shan-Shan , Zheng Yong-Gang , Wu Qingwen 
Published: February 2025

Abstract
C​​hanging-look blazars (CLBs) are blazars whose optical spectral lines at different epochs show significant changes and present a clear transition between standard FSRQ and BL Lacertae (BL Lac). Changing-look phenomena in blazars are highly significant for enhancing our understanding of certain physical problems of active galactic nuclei (AGNs), such as the potential mechanism of state transition in the accretion process of supermassive black holes in the central engine of AGNs, the possible intrinsic variation of the jet, and the connection between the accretion disk and the jet. Currently, the CLBs reported in the literature are still rare astronomical objects. In our previous work, we found that there are eight physical property parameters of CLBs located between those of FSRQs and BL Lacs. In order to search for more CLB candidates (CLBCs), we employed the mclust Gaussian mixture modeling clustering algorithm to perform clustering analysis for 255 subsets of the eight physical property parameters with 2250 blazars from 4FGL data release 3. We find that there are 29 subsets with three groups (corresponding to bl lacs, fsrqs, and CLBCs), in which there are four subsets with an adjusted Rand index greater than 0.610. The combined clustering results from the four subsets report that there are 111 CLBCs, which include 44 CLBs reported in previous literature and 67 new CLBCs, of which 11 are labeled as BL Lacs and 56 are labeled as FSRQs in the 4FGL catalog.

Abstract
Type Ia supernovae (SNe Ia) arise from the thermonuclear explosions of white dwarfs in multiple-star systems. A rare subclass of SNe Ia exhibit signatures of interaction with circumstellar material (CSM), allowing for direct constraints on companion material. While most known events show evidence for dense nearby CSM identified via peak-light spectroscopy (as SNe Ia-CSM), targeted late-time searches have revealed a handful of cases exhibiting delayed CSM interaction with detached shells. Here we present the first all-sky search for late CSM interaction in SNe Ia using a new image subtraction pipeline for mid-infrared data from the NEOWISE space telescope. Analyzing a sample of ≈8500 SNe Ia, we report evidence for late-time mid-infrared brightening in five previously overlooked events spanning subtypes SNe Iax, SNe Ia-91T, and super-Chandra SNe Ia. Our systematic search doubles the known sample and suggests that ≳0.05% of SNe Ia exhibit mid-infrared signatures of delayed CSM interaction. The mid-infrared light curves ubiquitously indicate the presence of multiple (or extended) detached CSM shells located at ≳1016–1017 cm, containing 10−6 to 10−4
M
⊙ of dust, with some sources showing evidence for new dust formation, possibly within the cold, dense shell of the ejecta. We do not detect interaction signatures in spectroscopic and radio follow-up; however, the limits are largely consistent with previously confirmed events given the sensitivity and observation phase. Our results highlight that CSM interaction is more prevalent than previously estimated from optical and ultraviolet searches and that mid-infrared synoptic surveys provide a unique window into this phenomenon.
