First-principles study of adsorption, dissociation, and diffusion of hydrogen on α-U (110) surface
Authors: Xu Zihan , Qin Chenglong , Yu Yushu , Jiang Gang , Zhao Liang 
Published: May 2024

According to the equilibrium crystal shape of α-U, the surface of α-U (110) is more stable and has a larger area fraction than α-U (001). Therefore, the adsorption, dissociation, and diffusion behaviors of H atoms and H2 molecules on the α-U (110) surface were systematically studied by first-principles calculations. The results show that there are only two stable adsorption sites for the H atom: the surface short-bridge site (SB1) and the subsurface short-bridge site (SB2). The adsorption of H2 molecules is divided into chemical adsorption of dissociated H2 molecules and physical adsorption of undissociated H2 molecules, and the LB2-ParL adsorption configuration is the most stable adsorption configuration for H2 molecule adsorption, with an adsorption energy of −0.250 eV. The work function and charge transfer show that adsorption of the H atom or H2 molecule leads to an increase in the work function value of the α-U (110) surface, which enhances the electronic stability of the α-U (110) surface. The projected density of states shows that when the H atom or H2 molecule is close to the α-U (110) surface, the 1s orbital electrons of the H atom will hybridize with the 5f/6d orbital electrons of the nearby surface and subsurface U atoms, and new hybridized orbital peaks appear near the −4.5 eV or −7.3 eV energy level. The climbing image nudged elastic band study shows that the surface free H atoms are very easy to diffuse between the surface short-bridge sites and the subsurface short-bridge sites but the diffusion between the short-bridge site and the triangular center site is extremely difficult.
The origin of Uralic-speaking groups from a historical genetic point of view
Authors: Németh Endre , Szeverényi Sándor 
Published: May 2024

Abstract
In recent years, a number of primarily linguistic studies have dealt with the origin of the Uralic language
family. These studies formulated important and, in some cases, novel results regarding the location of the Proto-Uralic homeland,
the classification of linguistic branches, the chronology and geographical aspects of migration routes, and even the
archaeological cultures embodying the migration routes. At the same time, our knowledge of the gene pool of the Uralic peoples has
also increased significantly. The aim of the present study is to identify parallels and discrepancies between the latest
linguistic and historical genetic results. We highlight several convergences between recent conclusions of linguistics and our
model based on Y-chromosome data. A key finding is a correlation between Uralic language sub-branches and N subgroups. The
direction and chronology of the eastward migration of these N subgroups may also shed new light on the Uralic-Chukchi,
Uralic-Yukaghir and Uralic-Altaic linguistic parallels.
A case study of comparative metaphor analysis in Finnish and Hungarian news texts
Authors: Bajzát Tímea Borbála , Gábor Simon 
Published: May 2024

Abstract
Despite remarkable previous results of cognitive linguistic analysis of metaphorization in Finnish and Hungarian
even in a cross-linguistic context (Huumo 2019; Máthé 2022), a systematic comparative study of the patterns of linguistic metaphors in these two languages is still to
be carried out. The aim of this paper is to fill this research gap by proposing a MIPVU-inspired protocol for metaphor
identification in languages with rich morphology and presenting the preliminary results of a small-scale corpus analysis. The
study is organized around the following questions: (i) How can we adapt and extend the original MIPVU method for agglutinative
Uralic languages like Hungarian and Finnish? (ii) How can we implement the adapted method in a collaborative parallel annotation
process of sampled news texts? (iii) What are the differences in metaphorical patterns between Finnish and Hungarian? The paper
details the adapted protocol of MIPVU for the Hungarian language (Simon et al. 2023),
and how it can be applied to Finnish, demonstrating its applicability in a research corpus. Our findings demonstrate a relatively
similar metaphorization in Hungarian and Finnish with slight differences in terms of the frequency of metaphorical expressions,
their semantic relations, and the complexity of argument structure constructions.

Published: May 2024

Abstract
The review emphasizes that factors such as feed type, diet composition, and hygiene standards during milking significantly impact milk yield, composition, and microbial population. A comprehensive methodology was employed to gather relevant literature from diverse sources, including textbooks, academic journals, and databases. The review focused on research articles investigating the impact of feed type and nutrients on dairy cattle milk yield, and quality. The search terms used to organize this article were breed, feed, hygienic practices, sources of microorganisms, and milk production, and by synthesizing findings from these studies; key factors influencing milk production and quality were identified. The review highlights the significance of breed selection, feeding practices, and hygienic measures in dairy farming. Optimizing these factors can enhance milk production, nutritional quality, and microbial safety, ensuring the delivery of high-quality milk to consumers. Overall, the review provides valuable insights into the relationship between animal breed, nutrition, and hygiene practices in dairy cattle production.

Abstract
We present a publicly-available code to generate sets of mock Lyman-α (Lyα) forest data that have realistic large-scale correlations including those due to the Baryonic Acoustic Oscillations (BAO).
The primary purpose of these mocks is to test the analysis procedures of the Extended Baryon Oscillation Survey (eBOSS) and the Dark Energy Spectroscopy Instrument (DESI) surveys.
The transmitted flux fraction, F(λ),
of background quasars due to Lyα absorption in the intergalactic medium (IGM)
is simulated using the Fluctuating Gunn-Petterson Approximation
(FGPA) applied to Gaussian random fields produced through
the use of fast Fourier transforms (FFT).
The output includes the IGM-Lyα transmitted flux fraction along quasar lines of sight and a catalog of high-column-density systems appropriately placed at high-density regions of the IGM.
This output serves as input to additional code that superimposes
the IGM tranmission on realistic quasar spectra, adds absorption by
high-column-density systems and metals,
and simulates instrumental transmission and noise.
Redshift space distortions (RSD) of the flux correlations are implemented by including the large-scale velocity-gradient field in the FGPA
resulting in a correlation function of F(λ) that can be accurately predicted.
One hundred realizations have been produced over the 14,000 deg2
DESI survey footprint with 100 quasars per deg2.
The analysis of these realizations shows that the correlations of F(λ) follows the prediction within the accuracy of eBOSS survey.
The most time-consuming part of the mock production occurs before application of the FGPA, and the existing pre-FGPA forests can be used to
easily produce new mock sets with modified redshift-dependent bias parameters or observational conditions.
Spatiotemporal changes and drivers of ecological security based on an improved ecological footprint model: the case of Hubei Province, China
Authors: He Nan , Zhou Zehan , Zhou Yong , Zhang Junda , Chen Deli , Cai Yurong , Zhang Mengxuan , Liang Xia 
Published: May 2024

Abstract
The increasing contradiction between resource supply and demand has brought ecological security (ES) to the forefront. Research on the changes of ES pattern and their driving factors is crucial for coordinating the regional ecological and economic development. Hubei Province in China exhibits uneven distribution of resources and a fragile ecological environment. In this study, an improved ecological footprint (EF) model was employed to analyze the changes in the ES pattern of Hubei Province. And the logarithmic mean Divisia index model was introduced to analyze the corresponding driving factors. The results showed that (1) from 2000 to 2020, the EF per capita (ef), the ecological carrying capacity per capita (ecc), and the ecological deficit (ED) per capita (ed) of Hubei Province increased by 47.11%, 2.71%, and 51.72%, respectively. In 2020, the cities in the province were in a state of ED, and the spatial distribution was ‘high in the central part of the province and low in the east and west’. (2) Each ef type showed an increasing trend. The increase in ef mostly came from the increase in fisheries ef, fossil energy ef and cropland ef, with a contribution of 76.70%. The increase in ecc is mainly due to the increase in freshwater ecc, with a contribution of 274.87%. (3) The ecological pressure in the province continued to rise and has been in a state of being completely unsafe. The efficiency of ecological resource use has increased, and the ecological structure tends to be rationalized, but the ecological-economic coordination has weakened. (4) The overall EF growth in the province is mostly driven by economic, population and footprint structure factors, while footprint intensity suppresses EF growth. Therefore, it is advised to boost investment in eco-friendly tech, foster green economy growth, and prioritize renewable energy development. This study can provide a reference basis for policy formulation on environmental sustainability and ecosystem management.
Co-existence of potentially sustainable indigenous food systems and poor nutritional status in Ho indigenous community, India: an exploratory study
Authors: Kapoor Ridhima , Sabharwal Manisha , Ghosh-Jerath Suparna 
Published: May 2024

Abstract
Indigenous food (IF) systems comprise culturally important foods derived from natural resources with shorter farm to plate chains, as compared to modern counterparts. These food systems are at epicenter of sustainable food systems with potential to alleviate malnutrition and protect ecosystems. The Ho indigenous community of Jharkhand have access to diverse IFs, yet experience malnutrition. A sequential mixed-method study was conducted to explore local food systems with assessment of diet quality and nutritional status of Ho women. Focus group discussions (n = 10) and free-listing (n = 7) were conducted to capture community’s perspectives on IF systems, associated sustainable attributes and perceived challenges towards IF utilization. Scientific names and nutritive values of IFs were documented through secondary review; in case of no information in literature, IFs were identified through ethnobotanist with nutritional analysis in laboratory. 24 h recalls (n = 284 in winter and n = 154 in monsoon) and anthropometric assessments (n = 273) were conducted to estimate women’s dietary diversity and nutritional status. Findings revealed rich traditional ecological knowledge (TEK) producing a diverse list of IFs (n = 243) mainly accessed from natural food environment (wild and cultivated). Among listed foods, 171 IFs were taxonomically classified and among these, nutritive values were documented for 121 IFs. Potentially sustainable traits of Ho’s IF systems included high nutrient density of IFs, community’s preference towards their consumption because of their flavorsome attributes, climate resilient properties and cultural heritage. However, impacts of climate variability, changing farming practices and market-integrated life ways challenged the sustained production, access and consumption of IFs. This was evident in poor diversity in diets (diet diversity scores of 2.9 in winter and monsoon) and chronic energy deficiency (36%) in women. The unique TEK systems of indigenous communities need to be integrated into mainstream policies and programs for safeguarding and promoting their potentially sustainable food systems to support food and nutritional security.

In this work we clarify various points that, to the best of our knowledge, were missing in the literature. We have two main results. First, we show that freezing the fermionic spin-1/2 Calogero–Sutherland model naturally accounts for the precise form of the Haldane–Shastry wave functions, including the Vandermonde factor squared. Second, we use the fermionic framework to prove the claim of Bernard–Gaudin–Haldane–Pasquier that the Yangian highest-weight eigenvectors of the

Quantum tunnelling and thermally driven transitions in a double-well potential at finite temperature
Authors: Christie Robson , Eastman Jessica 
Published: May 2024

Abstract
We explore dissipative quantum tunnelling, a phenomenon central to various physical and chemical processes, utilizing a model based on a double-well potential. This paper aims to bridge gaps in understanding the crossover from thermal activation to quantum tunnelling, a domain still shrouded in mystery despite extensive research. By numerically investigating a model derived from Caldeira–Leggett’s work on quantum Brownian motion, examining both Lindblad and stochastic Schrödinger dynamics, we offer new insights into the transition states in the crossover region. Contrary to a common belief that temperature strongly dampens all quantum effects, our findings reveal that under certain conditions temperature instead alters the nature of tunnelling from a deterministic and periodic process to a stochastic yet still very quantum phenomenon. This underscores the profound influence of quantum effects on transition rates and the critical role of temperature in modulating tunnelling behaviours. Additionally, we introduce a new model for quantum Brownian motion that takes Lindblad form and is formulated as a modification of the widely known model found in Breuer and Petruccione. In our approach, we remove the zero-temperature singularity resulting in a better description of low-temperature quantum Brownian motion near a potential minima. Despite these advancements, we recognize persistent challenges in accurately simulating the dynamics at extremely low temperatures for arbitrary potentials, particularly those that cannot be closely approximated locally by a quadratic function.

Published: May 2024

Abstract
Gamma ray measurements were carried out on wood sections of agarwood and shade trees to obtain its mass attenuation coefficients. Diameter of the blocks of agarwood (Aquilaria Malaccensis) is 17.0cm and shade tree (Khaya Senegalensis) sections are 24.0cm (branch) and 37.2cm (trunk). The radiation transmission measurement setup used a 0.5” x 0.5” thallium-activated sodium iodide detector, scaler ratemeter Ludlum model 2200 and collimated radioactive sources 3.5GBq Am-241 and 0.05GBq Ba-133 for the attenuation measurements. The dry density of agarwood trunk was 0.40±0.01 gcm−3. For the shade tree, the dry densities were 0.52±0.02 gcm−3 (branch) and 0.49±0.01 gcm−3 (trunk). At 59.6keV, the mass attenuation coefficient for the agarwood at diameter is 0.114±0.007 cm2g−1, and for shade tree (branch) is 0.136±0.004 cm2g−1 and 0.120±0.004 cm2g−1 shade tree (trunk). At 356keV, the mass attenuation coefficient for the agarwood at diameter is 0.081±0.003 cm2g−1, and for shade tree (branch) is 0.086±0.004 cm2g−1 and 0.068±0.028 cm2g−1 shade tree (trunk).

Published: May 2024

Abstract
The study investigated the dose of several organs in the computed tomography (CT) scan by using Al2O3 optically stimulated luminescent (OSL) dosimeters. The organs of right and left kidney, right pancreas, spleen and liver in an anthropomorphic human phantom were investigated for the dose received during the scan. The OSL dosimeters are embedded into custom-made wax and replace onto two selected slices of human body phantom where the selected organs are located. The phantom was scanned with by using adult abdomen protocol. The percentage differences of OSL doses reading compared to the previous study data and the international dose reference level (DRL). The doses obtained from OSL NanoDots® showed excellent agreement compared to XRQA film dosimeters with percentage differences within 5%. The doses measured by using OSL dosimeters in five organs were also within the range of the national DRL values by the Ministry of Health of Malaysia (MOH). These findings suggest that our results can be utilized to verify the doses received by internal organs during computed tomography abdomen protocols. The overall results indicated the suitability of OSL dosimeters for the indirect dose verification in the CT scan.

Abstract

Objective. Detection of the epileptogenic zone is critical, especially for patients with drug-resistant epilepsy. Accurately mapping cortical regions exhibiting high activity during spontaneous seizure events while detecting neural activity up to 500 Hz can assist clinicians’ surgical decisions and improve patient outcomes. Approach. We designed, fabricated, and tested a novel hybrid, multi-scale micro-electrocorticography (micro-ECoG) array with a unique embedded configuration. This array was compared to a commercially available microelectrode array (Neuronexus) for recording neural activity in rodent sensory cortex elicited by somatosensory evoked potentials and pilocarpine-induced seizures. Main results. Evoked potentials and spatial maps recorded by the multi-scale array (‘micros’, ‘mesos’, and ‘macros’ refering to the relative electrode sizes, 40 micron, 1 mm, and 4 mm respectively) were comparable to the Neuronexus array. The SSEPs recorded with the micros had higher peak amplitudes and greater signal power than those recorded by the larger mesos and macro. Seizure onset events and high-frequency oscillations (∼450 Hz) were detected on the multi-scale, similar to the commercially available array. The micros had greater SNR than the mesos and macro over the 5-1000 Hz frequency range during seizure monitoring. During cortical stimulation experimentation, the mesos successfully elicited motor effects. Significance. Previous studies have compared macro- and microelectrodes for localizing seizure activity in adjacent regions. The multi-scale design validated here is the first to simultaneously measure macro- and microelectrode signals from the same overlapping cortical area. This enables direct comparison of microelectrode recordings to the macroelectrode recordings used in standard neurosurgical practice. Previous studies have also shown that cortical regions generating high-frequency oscillations are at an increased risk for becoming epileptogenic zones. More accurate mapping of these micro seizures may improve surgical outcomes for epilepsy patients.
Equitable charging infrastructure for electric vehicles: access and experience
Authors: Bhatt Rudri , Giang Amanda , Javed Bassam , Kandlikar Milind 
Published: May 2024

Abstract
The shift toward electric vehicles (EVs) as a decarbonisation strategy in transportation raises important energy justice concerns, particularly regarding fair access to charging infrastructure. This perspective synthesizes evidence on how access to, and experience of, charging infrastructure may differ across socio-economic groups across North America. We present a framework for assessing charging infrastructure equity that includes: (i) accessibility—proximity, reliability, visibility, affordability; and (ii) user experiences—safety, payment ease, and co-located other services. The framework helps characterize the varied impacts across socio-demographic groups, including on low-income and marginalized communities. We explore how the direct and indirect effects of accessibility and user experience might influence the distribution and design of EV charging stations. Considerations of socio-economic diversity in the deployment of charging infrastructure are critical to ensure equitable benefits from electric mobility. We conclude that targeted actions from manufacturers, charging operators, and governments are needed to alleviate the disparities in access and experiences with public EV charging.

Published: May 2024

Abstract
The future of the automotive industry lies in the utilization of electric vehicles (EVs). A crucial component of these EVs is the drive motor. The verification of critical parameters for the electrical motor is considered to be of utmost importance, and this is achieved through the use of a motor testing machine. The motor testing machine is utilized frequently to determine characteristic curve points and the electromagnetic behavior of electric motors under various conditions. However, it has been observed that the presence of a fault in the helical gear setup of the testing machine leads to frequent breakdowns and suboptimal performance, thereby affecting the efficiency of the assembly line in the production of electric vehicles. In light of these observations, the main objective of this research endeavor is to improve the motor test bench apparatus by altering essential design parameters through the utilization of vibration signal analysis and machine learning techniques. Prior to extracting statistical features, vibration signals are obtained at different gear settings. These signals are subsequently categorized using classifiers such as Bagged Trees and Quadratic SVM. Machine learning techniques are utilized to classify the gathered signals as either normal or faulty, both with and without the inclusion of a 0.25 KW load for each condition. The performance of multiple algorithms is evaluated and scrutinized. The results have demonstrated that the Bagged Trees technique outperforms the other algorithm, achieving an impressive accuracy of 95.3%. Consequently, the proposed method presents an adept solution for augmenting the motor test bench’s capability by modifying crucial design parameters.
