Abstract
Surface engineering is concerned with the design and modification of the surfaces of bulk materials in order to give certain physical, chemical, and technical qualities that were not intrinsically included in the original bulk materials. Metallic glassy alloys containing copper and titanium, have lately emerged as desired antibacterial coating materials that may be used as protective coating. Cold spray coating method is an ideal process for temperature sensitive materials. The present investigation aim to develop a novel antibiofilm compound consisting of ternary Cu-Zr-Ni metallic glassy powders. At a temperature that was slightly higher than their glass transition temperatures, the spherical powders that made up the final product were used as feed stock materials for cold spray coatings applied to stainless steel substrates. It was discovered that the presence of the supercooled liquid region in the powders made the cold spray process more efficient, which ultimately led to the development of a technique of adhesion that was unparalleled in its efficiency. In addition, as compared to stainless steel by itself, the substrates that had been coated with metallic glassy were able to considerably suppress the development of E. coli colonies by at least one log

Abstract
A set of closed form expressions is proposed to compute the negative permittivity, the resonant frequency, the quality factor, the bandwidth, the input impedance and the gain of a coaxial probe fed microstrip metamaterial antenna. It is based on the cavity model, the transmission line model, the dynamic permittivity and the parallel resonant R-L-C circuit. The numerical results are compared with experimental results available in open literature and our new experimental results. We have also employed electromagnetic simulator to validate the model.

Published: June 2022

Abstract
Gels were used to perform localized dechlorination treatments on ferrous or copper alloy archaeological objects. Agar gel (3%w) was used as a medium for the electrolyte, a 1%w KNO3 solution. Localized electrolysis with gel was carried out using the same parameters as immersion electrolysis. This study shows that the technique results in the efficient extraction of chlorides. To determine the end of treatment, two tools were validated: determining the quantity of chlorides present in the gels by XRF and monitoring the oxygen consumption of an object before and after treatment.
Study of weak measurement amplification in simple optomechanical systems
Authors: DAS MANOJ 
Published: June 2022

Abstract
We have studied the ampliﬁcation in displacement of the mechanical mirror in a simple optomechanical system. Here photon number acts as system and the mirror acts as the meter. In the weak coupling condition, post selection of the photon number operator enhance the value of mirror displacement. The displacement of the mirror depends on the weak value of the photon number operator and on the value of relative phase(φ) between the pre and post selected states. Ampliﬁcation of the mirror can be seen for maximum coupling strength(.25Ω m ) in weak coupling criteria for optomechanical systems, Ωm being the mechanical frequency.

Published: June 2022

Abstract
Glioblastoma (GBM) is the most common malignancy tumor of central nervous system. PTBP3 was closely associated with the development of tumor. However, the function and mechanism of PTBP3 in GBM is little known. We found that PTBP3 was upregulated in GBM, and higher expression of PTBP3 corrected with the poor survival of GBM patients. Knockdown PTBP3 reduced proliferation, EMT, invasion, and migration of GBM. Conversely, overexpressing PTBP3 has an opposite effect. Moreover, we found that PTBP3 stabilized Twist1 by decreasing its ubiquitination and degradation. Furthermore, orthotopic xenograft models were used to demonstrate the PTBP3 on the development of GBM in vivo. This study proved that PTBP3 promoted tumorigenesis of GBM by stabilizing Twist1, which provided a new therapeutic target for GBM.

Published: June 2022

Abstract
In recent years, energy consumption and greenhouse gas (GHG) emissions are of major concern across the globe In this context, using data envelopment analysis, a study was done to determine the energy usage pattern and efficiency of rice farmers in the coastal state. The results showed that rice production systems had energy use efficiency, energy productivity, net energy, and human energy profitability of 2.40, 0.16 MJ/kg, 15728 MJ/ha, and 42.8, respectively. 5 and 21 farmers were judged to be efficient based on technical and pure technical efficiency, respectively. The mean scale efficiency of inefficient farmers was 0.68 which indicated the scope for refining agricultural practices to input use. Nitrogen, farmyard manure, and seeds have a positive impact on crop yield, whereas labor and diesel harm both crop yield and energy, according to the econometric model. The main non-renewable inputs contributing to GHG emissions are nitrogen fertiliser (72.1 kg CO2 eq./ha), fuel (68.5 kg CO2 eq./ha), and machinery (68.9 kg CO2 eq./ha). Indirect (81.7%) and non-renewable (73.8%) energy consumption was found to be higher than direct (18.3%) and renewable energy consumption (26.2%). Our findings suggested that farmers in this region should use conservation tillage and better crop management strategies to save energy and minimize GHG emissions.

Abstract
Aim at the problems that the genesis and deep dynamic mechanism of Paleozoic-Mesozoic granites in the north western margin of South Altun Mountains have not been analyzed on the whole, systematic petrographic and elemental geochemistry studies on granites in the eastern segment of South Altun Mountains were carried out. The lithology of the area is mainly granite, granodiorite and monzonite, with SiO2 of 57.35% ~ 88.11%, Al2O3 of 3.84%~19.56%, and total alkali content 1.00%~9.92%, with different degrees of Eu (Eu is 0.24~1.04), which belongs to the alkalic-alkali calcic-calc alkalic-calcic series, all of which have the characteristics of peraluminous, enrichment of large ion lithophile elements(LILE) and loss of high field strength elements(HFSE). Based on the results of previous studies and the classification of Sr-Yb, the Palaeo-mesozoic magmatism in this area can be divided into six episode: episode 1 (484-458 Ma) is the Nanling Mountains I-type granite, which may be derived from partial melts of metamorphic basalts; episode 2 (450~406 Ma) is Himalayan and Zhejiang mixed type granites, which have I-S and S type granites respectively, and the source areas are partial melts products of garnet amphibolite and metamorphic mudstone sandstone respectively; episode 3 (404~385 Ma) is the Nanling Mountains A2-type granite, which may be the partial melts product of the granodiorite at low pressure ; episode 4 (380~343 Ma) is the post-collisional uplifts of the Adakite and Zhejiang type granites, which are of type I granite and are related to the crustal detachment;and episode 5 (253~280 Ma) is the Nanling Mountains S type granites, It may be derived from the partial melts of metamorphic mudstone, which is the product of the closure of the Tethys Ocean; episode 6(154 ~ 230 Ma) is Himalayan I-type granite, and the source area is the partial melts product of meta-sandstone, which is related to subduction of residual ocean basin.
Genome-wide analysis of genes encoding core components of the ubiquitin system during cerebral cortex development
Authors: Bouron Alexandre , FAUVARQUE Marie-Odile 
Published: June 2022

Abstract
Ubiquitination involves three types of enzymes (E1, E2, E3) acting sequentially to attach ubiquitin (Ub) to target proteins. This post-translational modification controls key cellular processes like the degradation of proteins, endocytosis, subcellular localization and activity of proteins. The ubiquitination, which can be reversed by deubiquitinating enzymes (DUBs), plays important roles during brain development. Furthermore, deregulation of the Ub system is linked to the pathogenesis of various diseases including neurodegenerative disorders. We have used a publicly available RNAseq database to conduct an extensive genome-wide gene expression analysis of the core components of the Ub machinery, covering Ub genes as well as E1, E2, E3 and DUB genes. The ubiquitination network was merely governed by Uba1 and Ube2m, the predominant E1 and E2 genes, respectively. There expression was positively regulated during cortical formation. The principal genes coding for HECT (homologous to the E6-AP carboxyl terminus), RBR (RING-in-between-RING), and RING (really interesting new gene) E3 Ub ligases were also prominently regulated. Pja1, Dtx3 (RING ligases) and Stub1 (U-box RING) were the most highly expressed E3 Ub ligase genes and displayed distinct developmental expression patterns. Moreover, > 80 DUB genes were expressed during corticogenesis with two prominent actors Uch-l1 and Usp22 that were strongly up-regulated. Several components of the Ub system overexpressed in cancers were highly expressed in the cerebral cortex under conditions not related to tumour formation or progression. Altogether, this work provides an in-depth overview of the transcriptomic changes during the embryonic formation of the cerebral cortex. The data also offer new insight for the characterization of the Ub system and may contribute to a better understanding of its involvement in the pathogenesis of neurodevelopmental disorders.

Published: June 2022

Abstract
A field-circuit coupled finite element (FE) model of an angled vertical shear vertical wave (SV wave) electromagnetic acoustic transducer (EMAT) was established to investigate influencing factors of angled SV wave EMAT in high-temperature aluminum alloy detection. The FE model also considered equivalent circuits of the EMAT excitation and reception. Based on the FE model, we investigated the effect of temperature on the excitation current from the EMAT excitation equivalent circuit, EMAT generation efficiency, ultrasonic propagation and acoustic radiation field, EMAT reception efficiency, and output gain of the EMAT reception equivalent circuit. Subsequently, the influence of temperature on the detected ultrasonic wave signal was analyzed with a constant frequency method (CFM) of 2 MHz and variable frequency method (VFM) and verified by the experimental measurement with the aluminum alloy with temperatures ranging from 20°C to 440°C. The results show that for non-ferromagnetic metal materials such as aluminum alloy, the main reason for the declining ultrasonic amplitude at high temperatures is that the ultrasonic attenuation coefficient increases with the increasing temperature, followed by the power changing characteristics of the EMAT excitation and reception circuit with the rising temperature. When the temperature rises, the equivalent resistance of the excitation coil increases, the current of the equivalent excitation circuit and the input voltage of the preamplifier from the reception equivalent circuit decline, and the output gain decreases. With the increase in temperature, the experimental amplitude of the angled SV wave shows a downward trend. When the temperature is 440 ℃, the amplitude of the angled SV wave with VFM is 42.85% higher than that with CFM, and the SNR is enhanced by 4.9 dB. The application of VFM to detect high-temperature aluminum alloy can significantly increase the ultrasonic signal amplitude and improve the SNR of ultrasonic waves.

Abstract
Flood forests are vegetation subject to seasonal floods. Situated in flood plains, they are systems under continuous changes due to the pulses of flooding, following the watercourse. Although these are singular ecosystems, there are little publications that report the floristic structure in floodplains, especially in Southeastern Brazil. This study aimed to characterize the composition, structure and diversity of the arboreal community in a flooding gradient, comparing them with the non-flood adjacent formations, at the mouth of Paracatu River, a tributary of São Francisco River, Minas Gerais, Brazil. For the structural survey of the arboreal community, we used the plot method, installed on both sides of Paracatu River. The individuals were identified at the species level. We sampled 1,276 individuals belonging to 85 species and 32 families. The Shannon Index (H`) regarding to the total sampling was of 3.40 nat.ind, with Pielou evenness index (J`) of 0.76. In terms of species importance, the six most important species comprised 46% of the total index of importance value. By means of similarity analysis, it was possible to verify the grouping of species along the ecounits, demonstrating the substitution of species along habitats, resulted of the temporal difference of the flooding in the environments. In conclusion, the flooding regimes, frequency and intensity determine the ecology of the river plains.
Summer sunlight impacts carbon turnover in a spatially heterogeneous Patagonian woodland
Authors: Berenstecher Paula , Vivanco Lucia , Austin Amy T. 
Published: June 2022

Abstract
Purpose
We evaluated the importance of dry season (summer) sunlight on carbon (C) turnover in a Mediterranean-type climate ecosystem in the context of spatially heterogenous distribution of vegetation.
Methods
We manipulated summer sunlight exposure of litter and soil at the ecosystem scale in a natural Patagonian woodland over two years and evaluated its effect on C turnover in litter and surface soil. We measured decomposition of standing dead litter of dominant grass and shrub species, changes in labile C pools in soil microsites with and without plant litter, and potential enzyme activity of litter and both soil microsites, evaluating seasonal and legacy effects of summer sunlight exposure.
Results
Summer sunlight exposure significantly increased standing litter decomposition for both shrub and grass litter (p < 0.05). Additionally, summer sunlight significantly increased labile carbohydrate availability (saccharification) and potential microbial enzymatic activity of grass (but not shrub) litter. Interestingly, summer sunlight exposure also had effects on soil, reducing by 50% labile organic C while stimulating potential extracellular enzyme activity in both soil microsites, with and without plant litter.
Conclusion
Summer sunlight accelerates C loss from standing litter and soil consistently across patches of heterogeneously distributed vegetation. In addition, sunlight exposure demonstrated carryover effects on the acceleration of grass litter decomposition in the following rainy season. These results suggest that summer sunlight is an important and lasting control of C turnover at the ecosystem scale even in seasonally and spatially heterogenous ecosystems.
Why continuous lateral prone position ventilation should be used for patients acute respiratory distress syndrome living in the plateau of Xining, Qinghai
Authors: Han Jinhai , Siqing Ma 
Published: June 2022

Abstract
Prone position ventilation improves oxygenation and reduces the mortality rate in patients with acute respiratory distress syndrome (ARDS). However, conventional prone ventilation is not sufficient for patients with ARDS living at high altitudes. Accordingly, this report proposes the concept of continuous lateral prone ventilation, which achieves lung protection by improving arterial oxygen and lung compliance as well as reducing the driving pressure while applying positive end-expiratory pressure, in patients with ARDS living at plateaus.

Published: June 2022

Abstract
Purpose
In patients with acute circulatory failure, we tested the feasibility and accuracy of an approach based on echocardiography and lung ultrasound to evaluate fluid responsiveness (FR).
Methods
We enrolled 113 consecutive patients admitted to the Emergency Department High-Dependency Unit of Careggi University-Hospital from January 2015 to June 2020. We assessed the inferior vena cava collapsibility index (IVCCI) and the variation of aortic flow (VTIAo) during the passive leg raising test (PLR). We performed a lung ultrasound to verify the presence of interstitial syndrome. FR was defined as an increase in the VTIAo > 10% during PLR or IVCCI ≥ 40%. FR patients were treated with fluid and those non-FR with diuretics or vasopressors. The therapeutic strategy was reassessed after 12 hours and the goal was to maintain the strategy based on the initial evaluation.
Results
among 51 FR patients, at lung ultrasound, 15 patients showed basal interstitial syndrome and 4 all-lung involvement. One fluid bolus was given to 51 patients. Among 57 non-FR patients, 26 patients showed interstitial syndrome at lung ultrasound (basal fields in 14, all lungs in 12). We administered diuretics to 21 patients and vasopressors to 4 subjects. We had to change the initial treatment plan in 5 (9%) non-FR patients and in 6 FR patients (12%, p = NS). In the first 12 hours after the evaluation, non-FR patients significantly less fluids compared to those FR (1119 ± 410 vs 2010 ± 1254 ml, p < 0.001).
Conclusions
the approach involving echocardiography and lung ultrasound allowed an accurate evaluation of the FR among critically ill patients.
Quantum Advantage on Machine Learning Models
Authors: Tomono Takao , Natsubori Satoko 
Published: June 2022

Abstract
Quantum machine learning is one of most exciting prospective applications of quantum technologies. Quantum kernel SVM is one of most popular methods for classifiers. However, there are few reports that show the quantum advantage in learning model construction compared with classical learning models. In this work, we investigated the process of learning model construction of quantum machine learning by using an evaluation index and ROC space graph. The behaviour between quantum and classical machine learning is different, and the quantum learning model is the method to decrease the false positive rate from high false and true positive rates that is based on quantum superposition. In summary, we have demonstrated the effect of quantum superposition on quantum machine learning for the first time from actual experimental results. This truth supports that quantum machine learning can build an outline of learning models faster than classical methods even if the number of original data is smaller.

Published: June 2022

Abstract
The present study quantitatively and qualitatively analyzed the diatoms in samples of the surface sediments collected from the seas of Eastern Siberia and the Arctic Ocean (AO) in 2016 and 2018. Compared with the end of the last century, there were significant changes in species composition and quantitative ratio of the diatom assemblages in the sediments from the Arctic Ocean and the Laptev and East Siberian Seas (ESS). In contrast, the diatom assemblages in the sediments from the Chukchi Sea had not significantly changed in terms of species composition or quantitative ratio over the same three decades. The observed transformations in the diatom assemblages of the surface sediments were associated with substantial alterations in water temperature, current flow, salinity, admixture, ice melting, and prolonged ice-free periods associated with global warming in the Northern Hemisphere in recent decades. The foregoing processes have clearly had strong impacts on the environment and the biota of the Arctic region.
Mapping of glacial lakes and glacial lake outburst flood in Kinnaur district, Himachal Pradesh using remote sensing and GIS

Published: June 2022

Abstract
Glacial lake outburst floods (GLOFs) are a severe and escalating threat to livelihoods and infrastructure in high-mountain areas around the world. To implement a first-order assessment of GLOF risk across the Kinnaur district of Himachal Pradesh (HP), we combine modelling approaches that capture both current and future potential for GLOF triggering, quantification of affected downstream areas, and assessment of the underlying societal vulnerability to such climate-related disasters. As a result, the assessment takes into account both current glacial lakes and future lakes predicted to occur as glaciers retreat. Current hazard, vulnerability, and exposure indices are combined to indicate various risk 'hotspots,' demonstrating that high GLOF risk might occur well downstream from the glaciated headwaters where threats arise in some cases. Landsat images for the years 1989, 1998, 2008 and 2018 were used to map glacier lakes. Cartosat DEM (30 m) was used for computing topographic information including maximum, minimum, mean elevation, slope, and aspect. ArcGIS 10.8 was used to generate other characteristics such as area, slope, aspect, and drainage network. The maximum likelihood classification (MLC) algorithm was used to create the land use and land cover (LULC) maps using the supervised classification technique. To augment the findings, the study also uses the indices i.e. NDSI, NDWI, NDPI. based on the data a total of 39 glacial lakes were identified of which 10 lakes were found dangerous lakes having area > 0.1 Km2 Trans-national GLOFs originating in China's upper Satluj River Basin, in particular, pose a threat to eastern HP's downstream territories. In the future deglaciated scenario, most administrative units are expected to have a large increase in GLOF danger levels as lakes grow closer to steep headwalls, where impacts from falling ice and rock could trigger outburst occurrences. Strengthening resilience and capacities to lower the current GLOF risk will be a critical first step toward adjusting to future problems in such situations.
