Abstract

Stacking van der Waals crystals allows for on-demand creation of a periodic potential landscape to tailor the transport of quasiparticle excitations. We investigate the diffusion of photoexcited electron-hole pairs or excitons at the interface of WS2/WSe2 Van der Waals heterostructure over a wide range of temperatures. We observe the appearance of distinct interlayer excitons for parallel and anti-parallel stacking, and track their diffusion through spatially and temporally resolved photoluminescence spectroscopy from 30 K to 250 K. While the measured exciton diffusivity decreases with temperature, it surprisingly plateaus below 90K. Our observations cannot be explained by classical models like hopping in the moiré potential. Using a combination of ab-initio theory and molecular dynamics simulations, we demonstrate that low energy moiré phonons, also known as phasons, play a key role in describing and understanding this anomalous behavior of exciton diffusion. In particular, we show that the moiré potential landscape is dynamic down to very low temperatures. Our observations show that the phason modes arising from the mismatched lattices of a moiré heterostructures can enable surprisingly efficient transport of energy in the form of excitons, even at low temperatures.

Abstract
A new approach for the rapid and accurate correlation study of the nonlinear properties in the Transition Metal (TM) clusters based on the Deep Leave-One-Out Cross-Validation (LOO-CV) method is presented. This study shows that the DNN-based approach proposes a more efficient method for predicting several properties of the fourth-row TM nanoclusters in comparison with the conventional methods based on Density Functional Theory (DFT), which are computationally expensive and significantly time-consuming. The feature space or equivalently called descriptors are defined based on a wide range of electronic and physical properties. Considering the similarities between these clusters, the DNN-based model is employed to investigate the correlation between the TM cluster properties. The method together with the cosine similarity delivers significant accuracy in the order of at most 10− 9 for the prediction of total energy, lowest vibrational mode, binding energy and HOMO-LUMO energy gap of TM2, TM3, and TM4 nanoclusters. Based on the correlation errors, the most coupling TM clusters are obtained. In this regard, Mn and Ni clusters has the maximum and minimum amount of energy couplings with other transition metals, respectively. In general, energy prediction errors of TM2, TM3, and TM4 demonstrate comparable patterns while an even-odd behavior is observed for vibrational modes and binding energies. In addition, Ti, V and Co demonstrate maximum binding energy coupling to the TM2, TM3 and TM4 sets, respectively. For the case of the energy gap, Ni shows the maximum correlation in the smallest TM2 clusters while Cr dependence is highest for TM3 and TM4 sets. Finally, Zn has the highest error for HOMO-LUMO energy gap in all sets and consequently the maximum independent energy gap characteristics.

Published: March 2023

Abstract
Background
We meta-analyzed the available data on the influence of lymph node involvement (LNI) and lymphadenectomy on the prognosis of patients with uterine sarcoma.
Method
PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus, OpenGrey, and ClinicalTrials.gov were searched for articles related to LNI or lymphadenectomy in patients diagnosed with any of the following subtypes of uterine sarcoma: uterine leiomyosarcoma (uLMS), low-grade endometrial stromal sarcoma (LGESS), high-grade endometrial stromal sarcoma (HGESS), undifferentiated uterine sarcoma (UUS), and adenosarcoma (ADS). Data on the incidence rates of LNI, lymphadenectomy, and survival were independently extracted and pooled using a random-effects model. Heterogeneity was evaluated using the I2 statistic.
Result
A total of 25 studies with 19,926 patients were included in our meta-analysis. LNI was more common in patients with HGESS/UUS [rate 18%; 95% confidence interval (CI) 95%: 9–28%], but less in uLMS (rate 6%; 95% CI 4–8%), LGESS (rate 7%; 95% CI 4–11%), or ADS (rate 2%; 95% CI 1–3%). Lymphadenectomy did not improve overall survival in patients with LGESS [hazard ratio (HR) 1.21, 95% CI 0.95–1.54], ADS (HR 0.90, 95% CI 0.73–1.10) or uLMS (HR 1.14, 95% CI 1.03–1.27), but it did improve overall survival in patients with HGESS/UUS (HR 0.63, 95% CI 0.48–0.85). Lymphadenectomy did not improve disease-free survival in patients with uLMS or ADS (HR 0.87, 95% CI 0.61–1.26).
Conclusion
LNI is relatively infrequent among patients with uLMS, LGESS, or ADS, and lymphadenectomy in such patients does not appear to improve survival. In contrast, LNI is relatively common among patients with HGESS/UUS, and lymphadenectomy significantly improves overall survival. The available evidence supports routine lymphadenectomy for patients with HGESS or UUS, but not those with uLMS, LGESS, or ADS.

Authors: Shen RuMing , chen shuaijie , lei wenjing , shen jiayi , lv lingchun , wei tiemin 
Published: March 2023

Abstract
Objectives
Pro-, pre-, and synbiotic supplements improve cardiovascular risk factors. However, the association between nonfood pro-, pre-, and synbiotics and long-term all-cause and cardiovascular mortality have not been studied. Thus, our objective was to determine the impact of nonfood pro-, pre-, and synbiotics to all-cause and cardiovascular mortality.
Design, setting, and participants:
A retrospective, cohort study of 4837 nationally representative American participants aged 65 years or older with a median follow-up duration of 77 months.
Measurements:
all-cause and cardiovascular mortality.
Results
A total of 1556 participants died during the median 77 months follow-up, and 517 died from cardiovascular disease. Compared with participants without nonfood pro-, pre-, and synbiotics use, nonfood pro-, pre-, and synbiotics use reduces nearly 41% risk of all-cause mortality (hazard ratio 0.59, 95%CI 0.43 to 0.79) and 52% risk of cardiovascular mortality (HR 0.48, 95%CI 0.30 to 0.76). Such an effect persists in most subgroup analysis and complete-case analysis.
Conclusion and relevance:
In this study, we found a protective effect of NPPS for all-cause and cardiovascular mortality in Americans aged 65 years or older. Nonfood pro-, pre-, and synbiotics can be a novel, inexpensive, low-risk treatment addition for all-cause and cardiovascular mortality for older individuals.

Published: March 2023

Abstract
Background
Thyroid disease is more frequent in patients with systemic lupus erythematosus (SLE) than in the general population. The main purpose of this study is to evaluate the occurrence of immunological thyroid dysfunctions in Egyptian children with SLE in a single center and its relation to the disease activity and duration.
Methods
This is a cross-sectional observational study. The study included 50 children and adolescents with SLE. All patients were subjected to complete history taking, thorough physical examination. Thyroid profile, anti-thyroglobulin and anti-thyroid peroxidase antibodies were assayed using an enzyme-linked immunosorbent assay (ELISA) technique.
Results
Out of 50 patients, six were males (12%), and 44 were females (88%), with female to male ratio (F: M = 7: 1). Their ages ranged from 5–17 years, with a median of 12 years. Thirty-two of patients (64%) had thyroid dysfunctions, 19 (38%) were diagnosed with euthyroid sick syndrome, ten (20%) had overt hypothyroidism, three (6%) had subclinical hypothyroidism, and none of the patients had hyperthyroidism. Antithyroglobulin antibodies (Anti-TG) was normal in all patients of the studied group, and antithyroid peroxidase (anti-TPO) was elevated in one (2%) out of 50 patients. There was a significant negative correlation between free thyroxine (FT4) and disease duration with a p-value of 0.007. Moreover, by comparing the duration of the disease and thyroid antibodies (anti-TG, and anti-TPO), there was a significant negative correlation with p-values of 0.015 and 0.028.
Conclusions
Intermittent biochemical screening of thyroid function and anti-thyroid antibodies is recommended as part of the clinical profile in SLE patients, to identify clinical/subclinical thyroid disease. To intervene with the most convenient therapy whenever indicated.

Abstract
The highest resolution of images of soft matter and biological materials is ultimately limited by modification of the structure, induced by the necessarily high energy of short-wavelength radiation. Imaging the inelastically scattered X-rays at a photon energy of 60 keV (0.02 nm wavelength) offers greater signal per energy transferred to the sample than coherent-scattering techniques such as phase-contrast microscopy and projection holography. We present images of dried, unstained, and unfixed biological objects obtained by scanning Compton X-ray microscopy, at a resolution of about 40 nm. This microscope was realised using novel wedged multilayer Laue lenses that were fabricated to sub-ångström precision, a new wavefront measurement scheme for hard X rays, and efficient pixel-array detectors. The doses required to form these images were as little as 0.02% of the tolerable dose and 0.05% of that needed for phase-contrast imaging at similar resolution using 12 keV photon energy. The images obtained provide a quantitative map of the projected mass density in the sample, as confirmed by imaging a silicon wedge. Based on these results, we find that it should be possible to obtain radiation damage-free images of biological samples at a resolution below 10 nm.

Published: March 2023

Abstract
Understanding and predicting accurate property-structure-processing relationships for additively manufactured components is important for both forward and inverse design of robust, reliable parts and assemblies. While direct mapping of process parameters to properties is sometimes plausible, it is often rendered difficult due to poor microstructural control. Exploring the direct relationship between processing conditions and microstructural features can thus provide significant physical insights and aid the overall design process. Here, we develop an automated high-throughput framework to simulate an uncertainty-aware additive manufacturing (AM) process, characterize microstructural images, and extract meaningful features/descriptors. A kinetic Monte Carlo (KMC) model of the AM process is used as a digital twin to simulate microstructural evolution for a diverse set of experimentally relevant processing conditions. We perform a detailed parametric study to map the relationship between microstructural features and experimental conditions. Our results indicate that a many-to-one mapping can exist between processing conditions and typical descriptors. Multiple descriptors are thus necessary to unambiguously represent microstructural images. Our work provides crucial quantitative and qualitative information that would aid in the selection of features for microstructural images. Featurized microstructures could then be utilized to build data-driven models for predictive control of microstructures and thereby properties of additively manufactured components.
Feeding ecology and bioturbation of fiddler crab Uca princeps (Smith, 1870) (Brachyura, Ocypodidae) in a peri-urban wetland in an arid region

Abstract
Fiddler crabs are essential to understanding tropical coastal wetlands' dynamics and analyzing carbon budgets because they are the primary epibenthic biomass. They have a high consumption of detritus/bacterial biomass and generate high rates of bioturbation in sediments, affecting storage and export carbon budgets. In the present study, we analyzed the feeding ecology and bioturbation of Uca princeps with field experiments (i.e., daily food intake) and laboratory/analysis. This study estimated the daily food intake, evacuation rates, organic matter/carbon content, and bioturbation rate by feeding this species in two seasons (cold and warm). We found that the percentage of daily intake of U. princeps measured in dry weight in November 2008 was 16.2% and 17.4% for females and males, while in April, the food intake was much higher with 38.4% and 41.6%, respectively. The average bioturbation of this species through their feeding activities was ~ 0.3 Mg ha− 1 day− 1. The results suggest that the females are more selective in their feed. The evacuation rate was 0.84 h− 1 for females and 0.87 h− 1 for males. Therefore, U. princeps plays a vital role within the peri-urban ecosystem by removing/altering high quantities of organic matter from the sediments, transforming them into biomass, and influencing biophysical modifications in the peat.
Mixed potential function modeling and stability analysis of DC microgrid with hybrid energy storage

Published: March 2023

Abstract
Aiming at the large disturbance stability problem of hybrid energy storage DC microgrid with constant power load, based on deducing the equivalent model of hybrid energy storage system (HESS) pulse-width modulated switching network, a stability criterion and analysis method of DC microgrid containing the HESS based on mixed potential function theory is proposed. Firstly, considering the charge-discharge characteristics of HESS, the operating states of the DC microgrid system containing the HESS are divided into buck and boost operating modes. Then, the mixed potential function model of the DC microgrid system based on the equivalent model of pulse-width modulated switching network is established for the above two operating modes respectively; Finally, the third stability theorem of the mixed potential function theory is applied to derive the large disturbance stability criterion of the DC microgrid under buck and boost operating modes respectively. This criterion gives the stability operating conditions of each converter control parameter. The accuracy of the proposed stability analysis method and the validity of the mixed potential function criterion are verified by simulation.
Gas Chromatography-Mass Spectrometry (GC-MS) and 1H Nuclear Magnetic Resonance (NMR)-based profiling and phytochemical screening revealed industrially important metabolites in wild seabuckthorn (Hippophae salicifolia D.Don) berries
Authors: Singh Sugandh , Sharma Prakash Chand 
Published: March 2023

Abstract
In recent times, seabuckthorn (Hippophae Sp.) has attracted worldwide attention as a source of traditional medicines, nutraceuticals, and cosmeceuticals due to the presence of a wide range of bioactive phytochemicals These bioactive phytochemicals may vary in different regions of plant collections. The amount of plant materials traded within the State has increased dramatically in recent years as a result of the rising demand for herbal products. Moreover, there are no organized methods of seabuckthorn cultivation in Uttarakhand. Through experience and practice, the locals preserve their customary knowledge, which is passed down orally and without documentation. Currently, this information is in danger of disappearing. The scenario regarding the development of seabuckthorn as a future crop in the Uttarakhand region is very alarming. Most of the metabolomics research has been carried out on a single analytical platform. However, each platform has intrinsic advantages and drawbacks that can affect the analytical coverage of the metabolome. The present study was carried out to identify the entire unrevealed metabolites in H. salicifolia berries originating from Uttarakhand regions for the first time, utilizing both GC-MS and 1H NMR techniques. Phytochemical screening was performed by various qualitative and quantitative methods such as GC-MS and 1H NMR in H. salicifolia berry extract originating from three regions (Badrinath, Yamunotri, and Gangotri) of Uttarakhand (India). Phytochemical determination revealed the presence of industrially important metabolites. In total, 318 metabolites were identified, 305 by GC-MS and 13 by 1H NMR. These metabolites were classified in 23 sets of metabolites such as alkane hydrocarbons, alkene hydrocarbons, fatty acid methyl esters, etc. in which total metabolomic percentage and its amount was highly detected in the Gangotri region followed by Badrinath and Yamunotri. The present study provides valuable information for the identification of the natural source of metabolites related to the quality of various seabuckthorn-based products useful for applications in the food and pharmaceutical industries as well as for effective germplasm collection.

Abstract
The occurrence of pathogenic bacteria in poultry meat is of growing concern and another problem found on a global level is the continuous increase of antimicrobial resistance in bacteria isolated from food. This study aimed to evaluate the prevalence of pathogenic bacteria in poultry carcasses collected from Addis Ababa and Debre ziet areas and to reveal the most prevalent patterns of antimicrobial resistance in the isolated strains. A total of 30 chicken carcasses were evaluated according to standard microbiological methods. Coliform count showed that 8.99logcfu/g highest count and 5.01logcfu/g lowest. There was high prevalence of foodborne pathogenic bacteria in poultry meat. Forty percent Listeria ,56.7% Shigella, 43.3% Escherichia, 57.3% Staphylococcus and 40% Salmonella spp. of antibiotic resistant bacterial contamination was found from the 27 chicken meat samples. The study showed that most of the bacterial isolates showed high resistance to Amoxicillin (x̄= 66.24), Cefixime (x̄ =60.36), Erythromycin (x̄ = 59.92), and Tetracycline (x̄ =59.6). On the other hand, lower resistance was found to Chloramphenicol (x̄ =74.88), Ciprofloxacin (x̄=67.18) and Norfloxacin (x̄ =58.7). An alarming level of multiple antibiotic resistance (MAR) index of above 0.2 was observed all the bacterial isolates tested. The study revealed that these isolates represent an important reservoir in the spread of zoonotic diseases. The current finding suggest that the country urgently needs an integrated surveillance system within the entire chain, for drug-resistant pathogens isolated from poultry meat.
Highly Diverse Cuticular Hydrocarbon Profiles but No Evidence for Aggression Towards Non-kin in the Ambrosia Beetle Xyleborinus Saxesenii

Abstract

Animal societies have nestmate-recognition to protect against social cheaters and parasites. In most social insect societies individuals recognize and exclude any non-nestmate. There, the roles of cuticular hydrocarbons as recognition cues are well documented. Some ambrosia beetles live in cooperatively breeding societies, within nests that are almost completely isolated. Their fungus-farming and inbreeding habits within their nest ensure a nearly complete isolation. However, little is known about whether nestmate recognition is present and adaptive in these ambrosia beetle societies.
Here we studied the ability for nestmate recognition in the cooperatively breeding ambrosia beetle Xyleborus saxesenii, combining behavioural observations and cuticular hydrocarbon analyses. Laboratory nests of X. saxesenii were exposed to foreign adult females, from the same population, another population and another species and survival as well as behaviours of receivers and the donor individual were observed. We expected that increasing genetic distance would cause increasing distance in chemical profiles and increasing levels of behavioural exclusion and possibly mortality. Chemical profiles were different between populations and appeared as variable as in other highly social insects. However, we did not find any evidence for behavioural exclusion of foreign individuals. These results suggest that cuticular hydrocarbon profiles might be used for communication, but that exclusion of non-nestmates is absent in X. saxesenii. By contrast it may be adaptive for inbreeding ambrosia beetle species to accept non-nestmate to increase genetic diversity within nests.

Published: March 2023

Abstract
Currently, there is a big issue with waste, its processing and subsequent use. On the one hand, there are many initiatives to replace materials that are poorly biodegradable, but on the other, it is necessary to process and ideally use the waste that we have already produced. In this study, the properties of composite boards made of waste materials and biodegradable polymer were investigated. The composite boards were made from wood and plastic waste using high-energy milling technology. This technology for material preparation is promising as it includes controlling the morphology of particles, homogenising the mixture and drying the material during the milling process. Results show higher flexural strength of HDF boards compared to tested composites with one exception. Wood/PHBV composite exhibits 30% higher MOE than HDF due to its higher modulus of PHBV. The lowest thickness swelling (3%) and water absorption (12%) were measured for wood/HDPE composite. HDF boards recorded the lowest dimensional stability. The highest water absorption of tested composites was measured for wood/PHBV composite. Resistance to wood-rotting fungi was greatest for wood/PHBV composite containing marble powder, which corresponds to the results of scanning electron microscopy. The effects of both fungi (Coniophora puteana and Pleurotus ostreatus) in the decay test were similar.
