Published: August 2023

Considering the controversial benefits of video-assisted thoracoscopic surgery (VATS), we intended to evaluate the impact of surgical approach on cardiac function after lung resection using myocardial work analysis. Echocardiographic data of 45 patients (25 thoracotomy vs. 20 VATS) were retrospectively analyzed. All patients underwent transthoracic echocardiography (TTE) 2 weeks before and after surgery, including two-dimensional speckle tracking and tissue doppler imaging. No notable changes in left ventricular (LV) function, assessed mainly using the LV global longitudinal strain (GLS), global myocardial work index (GMWI), and global work efficiency (GWE), were observed. Right ventricular (RV) TTE values, including tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TASV), and RV free-wall GLS (RVFWGLS), indicated greater RV function impairment in the thoracotomy group than in the VATS group [TAPSE (mm): 17.90 ± 3.80 vs. 20.60 ± 3.50, p < 0.018; TASV (cm/s): 12.40 ± 2.90 vs. 14.60 ± 2.50, p < 0.010; RVFWGLS (%): −11.50 ± 8.50 vs. −17.50 ± 9.70, p < 0.033), respectively]. Unlike RV function, LV function remained preserved after lung resection. The thoracotomy group exhibited greater RV function impairment than did the VATS group. Further studies should evaluate the long-term impact of surgical approach on cardiac function.

Published: August 2023

Saline soil from the coast is a valuable resource that is readily available. It is also a valuable resource for reserving arable land. It has been demonstrated that adding organic fertilizers to salinized soils can effectively enhance them. However, since the improvement of saline soils cannot be achieved by a single measure, the effects of compound measures of organic fertilizers combined with mineral elements, humic acid, are significant and might be examined in depth. In order to explore the effects of various measures on the features of pH, electrical conductivity (EC), and nutrient changes in coastal salinized soils in Yancheng, Jiangsu Province, a ryegrass-alfalfa rotation with organic fertilizer as well as compound measures was designed. The findings indicated that the total nitrogen (TN) content of the soil increased and that all organic fertilizer composites decreased the electrical conductivity of the surface soil. However, the organic fertilizer with microbial fertilizer and humic acid was especially effective at regulating the pH and electrical conductivity of the surface soil during the time when salts were prone to accumulating. In conclusion, our findings point to new approaches to lowering salinity and boosting fertility in coastal saline soils: organic fertilizer with microbial fertilizers and humic acid, as well as organic fertilizer with Attapulgite clay.

Mesoscopic Deformation of a Hydraulic and Mechanical Aperture of a Single Fracture under Normal Stress
Authors: Ma Haichun , Wang Jingping , Qian Jiazhong , Luo Qiankun
Published: August 2023

Studies have focused on describing the interactions between the fluid flow characteristics and structural deformation of fractures at the mesoscopic scale, which is a scale between the macroscale and the microscale. In this work, a three-dimensional numerical simulation based on the Navier-Stokes equation was carried out to investigate the effect of normal stress on the fracture morphology distribution, the fluid flow characteristics distribution, and the interdependence between the flow and stress in a single mesoscopic fracture. Two fracture surfaces of a mesoscopic rough-walled fracture model were created. Results suggest that the nonlinear relationship between the normal stress and deformation due to the area of the total closure increases unevenly. Distributions of the mechanical aperture are approximated well by a normal distribution. Change in the fluid flow is due to the increase in the fractional contact area. The low-velocity zones are surrounded by relatively smaller apertures, which gradually close and join the areas of total closure. Under the limitation of the total closure areas of the two fracture surfaces, the appearance of channel flow behavior. Compared with the flow in the X- and Y-directions, normal stress-induced flow anisotropy occurred. The mesoscopic quantitative relationship between the strains in terms of the mechanical/hydraulic aperture was determined and proven. A macroscopic relationship between the intrinsic permeability and the strain was deduced, which enhances the evaluation and design of various geological engineering applications in which fracture deformation is considered.

Published: August 2023

—The Middle Jurassic sedimentary strata of Siberia remain poorly studied chemostratigraphically. We contribute to the knowledge with pioneering C, O, and Sr isotopic data for carbonate material of belemnites from the Yuryung-Tumus Peninsula and the lower reaches of the Lena River, as a basis for comprehensive description of the north Siberian Bajocian and lower Bathonian. The obtained chemostratigraphic constraints, with new 87Sr/86Sr ratios and previous δ13C and δ18O estimates, also include data for the lower Bathonian in the Sokur section (Central Russia). Despite the limited amount of material, chemostratigraphy, along with the available biostratigraphic data, allows reliable correlation of the Boreal sections with the primary standard of Northwest Europe, which is impossible for these strata with any of the two methods alone. The δ13C, δ18О, and 87Sr/86Sr patterns correlate with the records of eustatic, climatic, tectonic, and paleogeographic events. The new δ18O data and the inferred paleotemperatures for the latest early Bajocian and the Bajocian/Bathonian boundary reveal two excursions of notable seawater warming near the Siberian Arctic coast, which were synchronous with episodes of global sealevel rise. It was presumably during the eustatic events that the N–S Komi Strait (first naming) opened twice in the territory of the Russian Plate. The strait connected the Boreal and Tethyan seas and thus changed the oceanic circulation patterns. Specifically, it opened a gateway for a warm current from the south to northern Siberia responsible for the high seawater temperatures recorded in the δ18О patterns of belemnites.

Este estudo propõe investigar o funcionamento enunciativo do substantivo PORTA, em português brasileiro (PB), com intuito de apreender sua identidade semântica. Sob a luz da Teoria das Operações Predicativas e Enunciativas (CULIOLI, 1990, 1999a, 1999b), para a qual o sentido de uma unidade lexical constrói-se na relação que estabelece com os demais elementos que constituem o sintagma nominal por ele evocado, busca-se evidenciar a invariância própria da unidade linguística. Para tanto, utilizamo-nos das práticas de glosa, parte fundamental do quadro teórico-metodológico, que se inscreve no campo da Linguística Enunciativa. Por contemplar a manipulação e reformulação das unidades, sustentada pela atividade epilinguística, a glosa é concebida como prática de grande importância para o ensino do substantivo em sala de aula, por primar pela reflexão e observação do funcionamento lexical.

Published: August 2023

Este estudo aborda como a oralidade é responsável pela compreensão dos textos orais em detrimento dos textos escritos, sendo ela objeto de desenvolvimento de competências e habilidades conforme determinado pela BNCC (BRASIL, 2018). Logo, observou-se a condição da prosódia em relação às gramáticas, levantando-se a discussão sobre o que há na BNCC quanto à importância dessa competência para a formação comunicativa dos falantes. Além disso, fez-se uma pesquisa com 291 pessoas, do Ensino Médio incompleto à Pós-graduação completa, sobre a interpretação do sentido de orações subordinadas causais e coordenadas conclusivas em textos escritos e orais. Assim, notou-se que houve mais erros de identificação quando ocorria somente a leitura autônoma do que quando os períodos eram lidos por um locutor, demonstrando que a entoação influencia a efetiva interpretação do sentido da sentença.
Padrões discursivos na dialética entre os livros de defesa dos EUA e da China
Authors: Peixoto Rafaela Araújo Jordão Rigaud , Pires Karina Coelho
Published: August 2023

Novas facetas de multilateralismo têm motivado realinhamentos de relações de poder tradicionais, estabelecidas globalmente, especialmente em contextos envolvendo os Estados Unidos e a China. Esse novo ambiente estratégico em potencial é evidenciado não apenas pelas mudanças realizadas na versão de 2020 do Livro Branco de Defesa Nacional (LDBN) do Brasil, mas também na dialética entre os Livros de Defesa dos Estados Unidos (2017) e da China (2019), que parecem apontar diferentes estratégias para ações de cooperação global. Para investigar esses realinhamentos e seus possíveis impactos no setor de defesa brasileiro, a análise foi realizada em duas fases: (1) apreciação de características gerais dos Livros de Defesa dos EUA e da China; e (2) comparação de discursos expressos nos capítulos sobre cooperação internacional em cada Livro de Defesa. Os padrões discursivos investigados, consoante os arcabouços metodológicos de semântica lexical (L’HOMME, 2020; PEIXOTO; PIMENTEL, 2020) e de análise crítica do discurso (FAIRCLOUGH, 2003), sugerem que elementos de campos semânticos, de intertextualidade e de modalidade presentes no discurso servem como parâmetros que poderiam contribuir para a apreciação de ações de cooperação e de dissuasão a serem adotadas pelos EUA e pela China no século XXI.

Published: August 2023

O objetivo deste artigo é argumentar sobre processos de referenciação e negociação de sentidos em contextos face a face, entre crianças com SD e terapeutas da linguagem. Mostramos a perspectiva do Sistema de Referenciação Multimodal (ÁVILA-NÓBREGA, 2017). Nossa vertente de Multimodalidade postula que a língua é uma matriz cognitiva da mescla gesto-fala, não uma hierarquia entre elementos linguísticos e extralinguísticos (MCNEILL, 1985, 2013). Os dados são de gravações de atendimentos de duas crianças com SD (07 e 09 anos). A pesquisa é qualitativa, longitudinal. Os resultados apontam para o jogo dialógico de negociação de sentidos por meio de um sistema cíclico de produções dos sujeitos nas cenas, no qual emergem relações linguísticas de associação e repetição de objetos de discurso.

Published: August 2023

A quick assessment of the merits of various development strategies can be performed by operating companies whilst having a tool at their disposal consisting of all elements of a production system. To fulfil this requirement, an Integrated Production Model (IPM) of a giant onshore gas field in the Indus Basin of Pakistan was developed. This paper aims to highlight the workflow and lessons learnt in development and calibration of the model. It also showcases the utility of such models. The field in this case study consists of a single giant volumetric reservoir containing dry gas fluid. There are more than one hundred production wells and over 300 km of surface pipeline network. This study had two phases, in the first phase, key elements of the production system i.e. reservoir, wells and surface facilities were modelled and calibrated independently. Reservoir is modelled via multi-tank approach wherein each tank represented a different pressure region of the reservoir. Communication between the tanks was modelled through inter-tank transmissibilities. The surface network was broken down into clusters for ease of development and calibration. After completing calibration of the key elements explicitly; individual elements were brought together to form an integrated production system in GAP and the integrated response of the model is matched against the observed performance which completed the first phase of the study.

During second phase, the history matched IPM Model is then used for evaluating the impact of potential development activities in forecast mode aimed for increase in the delivery pressure, field plateau extension and reserves acceleration & increment. Development activities include infill drilling, tubing optimization, acid-stimulation, surface de-bottlenecking and nodal/wellhead compression. This allowed for ranking of the development activities based on their impact in an integrated mode. Furthermore, the impact of variable delivery pressure and scheduling of different scenarios was also highlighted. The paper also highlights the limitations of the integrated model requiring the use of assumptions in development and calibration phase, particularly with regards to the subsurface model for accurately predicting water rates. The importance of updating the model as part of routine functions is also deliberated.

It was concluded that for making short to medium-term prediction runs and evaluating development strategies, the IPM is an extremely useful tool. It is strongly recommended to develop an IPM early in the field life and plan reservoir management activities & surface network accordingly.

The demonstration of the calibration methodology, workflows and development strategies aided with examples in a unique setting provide a renewed opportunity to develop an understanding on developing and maintaining integrated production models.
The Characterization of Geological Flow Units in Carbonate Reservoirs - Integration of Core, Log & Production Logging Data

Published: August 2023

Geological flow units based on reservoir rock typing can be used to characterize geological facies based on their dynamic behavior. A procedure for identifying and characterizing geological flow units helps resolve some of the key challenges faced in exploration and production of carbonate reservoirs. The current work focuses on the rock typing/flow units classification for reservoir characterization in a carbonate gas reservoir. The Sui Main Limestone (SML) Eocene reservoir, located in the southwestern part of the Middle Indus Basin in Baluchistan Province was selected, and the study carried out using core, wireline logs of 30+ wells and production logging data. The reservoir was previously categorized based on the geological information into four layers.

An integrated workflow was used for characterization of Geological Flow Units based on all available information. The Sui Main Limestone (SML) reservoir was divided into three flow units/rock types, depending on the well log patterns, core data, Porosity–Water saturation relationships, flow zone indicators (FZIs), and the Porosity–Permeability relationships. Production logging data was used to validate flow unit classification.

The field is a gas bearing reservoir composed of medium hard to hard limestone characterized by high porosity but poor/low permeability. The matrix permeabilities and porosity range from 0.01–40 mD and 0–35 percent respectively. Three rock types and groups have been identified in the SML formation; the first group represents the poor reservoir quality (GFU-1) Highly cemented limestone, the second group reflects the moderate reservoir quality (GFU-2) Moderately cemented limestone, and the third group represents the very good reservoir quality (GFU-3) poorly cemented limestone.

Production logging data was used to validate flow unit classification. Pressure Transient Analysis (PTA) indicated that only partial penetration occurred, and therefore only a portion of the perforated area was contributing to production. Specifically, the majority of inflow zones identified in the production logging data corresponded to GFU-3 flow units. As expected, the other two flow units only provide a small increase in production. This further validated the partial penetration model determined from PTA.

Geological flow units/rock types in these thick carbonate reservoirs and can be helpful in selecting optimum perforation intervals rather than perforating the whole thickness. This innovative method can save significant CAPEX without compromising the production.

Published: August 2023

Base management provides framework for managing the production base and maximizing recovery through efficient depletion. A vital element of base management practice is system optimization which includes modelling, prioritizing, and implementing strategies to enhance production & reserves of all fields. The process starts with a holistic network model1 that includes integrating reservoir, wellbore hydraulics, gathering system and production facilities. System wide evaluation is conducted using this integrated model and recommendations are networked with cross-functional teams. Finally, these observations are ranked and executed as per business requirements. Given the vast number of active/shut-in wells & fundamentally different field types operated by UEP, this approach is pivotal to effectively manage base production.

This study focuses on key achievements in past few years which delivered fruitful results in terms of production and reserves addition. Below is the summary of activities:

Area-1 comprises of aging fields and the focus has been on creating network flexibility, re-accessing bypassed zones, and compressors modifications to bring the system in the most optimized operating window. Area-2 is primarily gas producing region and opportunities on Well hydraulics, surface compression, system de-bottlenecking, and plant optimization remain in the forefront. Figure-3 demonstrates a case of successfully managed base through multiple optimization activities.

The initiatives discussed in this study significantly contributed to optimizing base production of Area-1 & 2, enabling them to maintain optimum production levels.

Published: August 2023

In this work, a catalytic combustor for micro electrical mechanical system for
syngas was designed and analysed using Direct Numerical Simulation (DNS) in conjunction with
finite rate chemistry. The effect of catalyst (platinum (Pt), palladium (Pd), palladium oxide (PdO),
and rhodium (Rh)), bed type (packed with twelve catalyst shapes and four catalyst monolith),
shapes (packed: cylinder, hollow cylinder, four cylinder, single cylinder, single cylinder, crosswebb,
grooved, pall-ring, hexagonal, berl-saddle, cube, intalox-saddle, and sphere, monolith:
triangular, rectangular, hexagonal, and circular), and operating conditions (inlet temperature and
velocity, fuel/air ratio, different concentrations CH4-H2-CO) on combustion efficiency and
pressure drop were studied using different parameters (combustion efficiency (η), pressure drop,
effectiveness factor ( ψ ), and fuel conversions (H2 and CH4 conversions)). Analysis under
different operating conditions reveals that the designed combustor can operate effectively with
syngas of varying compositions with a high combustion efficiency of over 85%. Combustion
mainly takes place on the surface of the catalyst without gas phase reaction with pressure drops
between 18 Pa to 155 Pa. The intalox saddle shape catalysts resulted in the bed effectiveness factor
0.931. The Damköhler for hydroxyl radicals (OH) over the entire length of the reactor is uniformly
distributed and well below 3, suggesting uniform combustion.
Comprehensive Morphometric Analysis of Apple Fruits and Weighted Class Assignation using Machine Learning
Authors: Dujak Christian , Jurado Federico , Aranzana Maria Jose
Published: August 2023

Fruit morphology description for variety registration or evaluation is mostly based on human visual inspection. However, the development of an objective and efficient method for evaluating apple fruit shape would be of significant value. Furthermore, if this method can provide a comprehensive assessment of the multiple attributes encompassed by the term “shape”, it would have great potential for genomic studies. Here, we investigated the potential of a shape analyzer software originally developed to study tomato fruits (Tomato Analyzer) for the morphometric description of apple fruits. We conducted an analysis of 12,920 images of apple sections from 364 genotypes, collected across three harvest seasons. Also, we assigned the images into classes by visual inspection. The software detected the contour of the fruits in most of the images, but with some degree of imprecision, particularly in the stalk and calyx regions. After manual correction of the contours, we obtained 15 measurements of shape and size attributes. In general, size traits had higher heritability (H2) than shape traits (0.72 vs 0.45 in average, respectively). A Random Forest model was used to identify the most important variables determining fruit shape. The fruit shape index external I (FSII) outstood in importance, followed by the fruit shape triangle (FST), the distal angle Macro (DAMa), the eccentricity (ECC), and the proximal angle macro (PAMa). Incorporating these parameters into fruit description guides could provide more precise descriptions of apple cultivars. Additionally, this data will be useful to investigate the potential genetic control of these traits through genomic studies.

Loop-mediated isothermal amplification (LAMP) does not require thermal cycler machines to amplify DNA and has the potential to revolutionize molecular biology by bypassing the need for sophisticated equipment. The method also has a low running cost and short turnaround times with higher sensitivity when compared with many other amplification methods. The objective behind this study was to introduce a new platform for LAMP assay with improved sensitivity. In order to do such, Leishmania spp parasites were used as the study model for the investigation purposes. A new primer set (four primers plus two extra ones) were designed and optimized for the novel LAMP assay which we further assigned the name “NESTED-LAMP”. The primers target included ITS1 gene locus of cutaneous leishmaniasis (CL) to enhance the assay sensitivity. The minimum of detection of this new assay was further compared with the traditional LAMP assay, polymerase chain reaction (PCR), and real-time PCR (RT-PCR) methods. NESTED-LAMP detected 1 parasite/µL while the conventional counterpart technique was able to detect 105 parasites/µL. The sensitivity of PCR and RT-PCR declined when the concentration of parasite/µL was below 105 and 102, respectively. Furthermore, this study demonstrated 100% specificity and sensitivity regarding the NESTED-LAMP method. This method could be employed as a suitable alternative for diagnostic purposes as the results demonstrated a 105-fold improvement in sensitivity for the NESTED-LAMP approach compared with the conventional counterpart technique. Also, the cost-efficiency with higher sensitivity and specificity ensures the accuracy of the results.
Does climate variability influence internal migration flows in Senegal? An empirical analysis
Authors: Diallo Alassane
Published: August 2023

This paper aims to estimate the total effect of climate variability on inter-regional migration flows in Senegal. We match regional climate data at origin, represented by normalised rainfall and normalised temperatures (maximum and minimum), with regional migration flow data from Senegal's Agence Nationale de la Statistique et de la Démographie (ANSD) censuses to construct a panel database covering the five-yearly internal migration waves of 1976, 1988, 2001 and 2013. Using a gravity equation model where migration flows are explained by measures of climatic variability at origin, controlled for geographical, socio-economic and demographic factors traditionally identified in the literature. Our results show that only negative precipitation anomalies at the origin area act as a push factor and accelerate emigration. In the predominantly agricultural regions, rainfall deficits appear, alongside traditional socio-economic variables, as an additional significant factor shaping mobility across the country.
Multi-Objective Linear Optimization on Immediate Distributing poultry with Time Windows: Modellings and Applications

Published: August 2023

The informatization popularization in livestock and poultry breeding industry has become the mainstream development trend. The optimal scheduling of poultry is mainly divided into two categories: the optimal design of resource allocation and the maximum carrying capacity of existing equipment. This article proposes a multi-objective optimization model which can reduce the cost of transports, improve the efficiency of transferring, save manpower costs, and decrease the death rate of poultries.
Two versions of the model are proposed from different views. One is a sophisticated, elaborated and ideal model, which considers all conditions. It can obtain a best solution with high computational complexity.The other one is a simplified and concise version which can be applied to the real production more easily. It can obtain an acceptable solution with high speed. The time window method based on multi-objective mixed integer is introduced. An optimization method based on adaptive algorithm is adopted. The optimization model decomposed into several sub-models to reduce the data scale and obtain the sub-optimal feasible scheme.
Experiments are implemented for two situations. The latter optimization scheme is more suitable and easy for the actual production and operation environment and the result is simple. The former optimization scheme is conducive to the further study of the optimization scheme and easy to expand the application scenes. The model and the two solutions proposed in this article not only solve the problem of optimal scheduling of poultry distribution, but also have strong stability and practical application value. The code and simulated data are available at: https://github.com/Hu-s-h/Poultry-Model.

Published: August 2023

Understanding the atomistic structure of the active site during catalytic reactions is of paramount importance in both fundamental studies and practical applications, but such studies are challenging due to the complexity of heterogeneous systems. Using Pt/CeO2 as an example, we reveal the dynamic nature of active sites during the water-gas-shift reaction (WGSR) by combining multiple in situ characterization tools to study well-defined CeO2 nanoshapes with different exposed facets. We show that metallic Pt is present on the CeO2(111) surfaces, while oxidized Pt species are dominant on CeO2(110) and (100) surfaces after O2–H2 pretreatment. The different concentrations of interfacial Ptδ+ – O – Ce4+ moieties at Pt/CeO2 interfaces are responsible for the rank of catalytic performance of Pt/CeO2 catalysts: Pt/CeO2-rod > Pt/CeO2-cube > Pt/CeO2-oct. For all the catalysts, metallic Pt is formed during the WGSR, leading to the transformation of the active sites to Pt0 – Ov – Ce3+ and interface reconstruction. These findings shed light on the nature of the active site for the WGSR on Pt/CeO2 and highlight the importance of combining complementary in situ techniques for establishing structure-performance relationships.
“Togetherness” of superior mesenteric vein and ileocolic artery: how 3D CT based understanding of unusual anatomy influences the approach to D3 lymph node dissection
Authors: Efetov Sergey , Zubayraeva Albina , Rychkova Arina , Zubayraeva Amina
Published: August 2023

Purpose: There are several uncertainties on proper borders for D3-lymph node dissection (D3LND) in right colon cancer. To standardize the approach to lymph node dissection, superior mesenteric artery (SMA) or superior mesenteric vein (SMV) were suggested as anatomical landmarks. There is still no consensus, if SMA or SMV should be accepted as a surgical trunk for D3LND. Moreover, spatial vascular anatomy of ileocolic vessels in relation to SMV and SMA should be considered to reach complete lymph node dissection.
Methods: A 62-year-old female was presented with hepatic flexure colon cancer. On computed tomography (CT) scan it was shown that SMA was laterally to the left from SMV. SMV in its distal part was passing along ileocolic artery in caudal direction. To completely excise the lymph nodes, SMA was considered as a landmark to remove the mesocolic tissue between SMA and SMV.
Results: As a result, 25 lymph nodes (LNs) along SMA and 8 lymph nodes along SMV were harvested. There were no metastatic lymph nodes found along SMA and SMV.
Conclusion: This case demonstrates the importance of spatial anatomy consideration in defining landmarks to perform complete lymph node dissection.
The so-called arteriovenous flap can be considered as an important area of mesocolic root, which may contain lymph nodes and should be excised to perform complete lymph node dissection.
A Novel Non-Parametric Data Envelopment Analysis (DEA) Approach in Sub-basin Prioritization for Watershed Management in the Kumari River Basin, India
Authors: Jaman Md. Hasanur , Roy Subha , Das Souvik , Chatterjee Jaya , Sengupta Somasis
Published: August 2023

In a country like India where economy of the area is predominantly based on agriculture, a maximum proportion of people are dependent upon cultivation and therefore the soil health plays as engine to the enhancement of the agricultural productivity. Continuous soil erosion leads to the loss of top soil that has been responsible for systematic degradation of the soil and natural environment with time. In this context, watersheds, as a scale of natural boundaries, can be applied to implement a comprehensive soil management plan for the systematic conservation of the soil resource. In this situation, watershed management has emerged as a new approach that is based on the interrelationships between landuse, soil, and water and the process of planning and management of land, soil, water resources as well as the biotic resources. It is well accepted that the measurement of actual soil loss is not possible, so different proxies and prediction-based models of erosion susceptibility have been widely used for assessing the soil loss. Sub-basin prioritization with respect to erosion susceptibility, therefore, has become increasingly popular in the last few decades as this helps in optimal distribution of resources for management. In a country like India, where the availability of resources is limited, optimal distribution of resources becomes a challenge. Erosion is a complex problem wherein a large number of factors play an important role in influencing this process. Therefore, Multi-Criteria Decision Making (MCDM) techniques are now becoming more popular in this aspect. However, there are a myriad parametric and non-parametric MCDM models have been used to measure sub-basin soil erosion susceptibility. In terms of the non-parametric techniques, the most common are composite ranks. But the linear programming algorithm-based Data Envelopment Analysis (DEA) technique takes into account one possible optimal solution based on a number of solutions. Although the DEA technique is extremely popular in the domain of business management, this approach has never been used in the domain of resource and hazard management. So, this study is a novel approach in this field where the DEA technique has been introduced for sub-basin prioritization. The approach that has been included for this study is one of profit maximization i.e., the maximum efficiency of the sub-watersheds in terms of erosion susceptibility. So, the basins which are characterized by higher DEA scores are experiencing greater risk of erosion (and hence require prioritization). In the Kumari Basin, the sub watershed wise erosion susceptibility does not show any spatial pattern. The most erosion susceptible sub-watersheds which require the greatest priority for the right bank watersheds as compare to the left bank tributary include DMDR041R013, DMDR041R002, DMDR041R009, DMDR041R016 and DMDR041R014.

Virtual reality has some well-known limitations when the user walks naturally. A user experiencing virtual reality may collide with the limits of the physical workspace. To solve this, there exist techniques, such as the redirected walking methods, that try to trick the human brain to avoid these limits. However, these methods require good predictions of where users want to go in the future. On the other hand, Deep learning is helping in so many areas to make accurate predictions. Specifically, Long short-term memory obtained promising results in this virtual reality prediction task giving us clues to continue researching in this line. This manuscript presents an experiment carried out with 44 participants collecting positional data. These data have been used to test different existing prediction algorithms. In addition, a way to improve the previous results obtained with deep learning is presented. These results are achieved with the use of rotation quaternions and various positional data in three dimensions. The authors strongly believe that there is still much room for improvement in this research area.

In this study, we perform a retrospective analysis of the mid-term clinical results of distal radius fractures treated with the 3-point positioning technique using a minimally invasive plate osteosynthesis (MIPO) while preserving the pronator quadratus (PQ). The 3-point positioning technique was applied: the Kirschner wire was inserted after fluoroscopy and was correctly adjusted the position of the plate above the PQ. With the aid of Kirschner wires positioning the PQ stripping was performed only once, and the plate then placed in a correct and satisfactory position. Operation time, incision length, wrist pain score, upper extremity function DASH score, wrist Gartland-Werley score, wrist grip strength, and range of motion (ROM) were among the quantitative variables recorded. Qualitative variables including AO fracture classification, intraoperative and postoperative complications were evaluated. Twenty patients were enrolled in the study with an average follow-up of 6.8 ± 0.76 months. Of these, 8 males and 12 females were enrolled. the DASH score for the upper limb was 4.7 ± 1.3, and the Gartland-Werley score for wrist function was 11.9 ± 2.5 at the last follow-up. Mean flexion was 97.3%, extension was 97.1%, pronation was 98.8%, supination was 98.6%, and grip strength was 86.1% compared to contralateral values. No unfavorable intraoperative or postoperative complications occurred. The 3-point positioning technique can greatly minimize the damage to the PQ muscle and is a safe and effective method for MIPO for distal radius fractures.

Marine resources and industry have emerged as one of the most crucial cornerstones of global economic development. Be that as it may, erosion of materials is dependably the most difficult issue to the foundation and gear served in the marine environment. Scientists have tracked down that microbiologically influenced corrosion (MIC) and marine bio-fouling are two fundamental components of marine erosions because of the muddled marine environment and marine creatures. Herein, we firstly synthesized a novelty composites of graphite incorporated epoxy composites and took thermomechanical tests like differential filtering calorimetry (DSC), and tensile test for the strength of the materials. The outcomes showed a conspicuous improvement of mechanical properties in the adjusted resin system. Besides, the developed graphite-epoxy nanocomposite was gone through the electrical conductivity test for the movement of electron into it. Marine field tests revealed that graphite embedded epoxy nanocomposites showed excellent antifouling execution inside ninety days. In a nutshell, the graphite-epoxy nanocomposites have extraordinary mechanical properties and brilliant impedance properties, showing high potential in the marine antifouling field.

Polyphagy is an adaptative strategy allowing species to develop and survive on multiple diets. Phytophagous insects can be exposed to sub-optimal resources, as host plants vary in nutritional quality. Some insects may rely on symbiotic bacteria to better utilize less favorable substrates. The invasive fruit fly Drosophila suzukii is a highly successful pest worldwide. The use of ripening and ripe fruits, a niche neglected by other drosophilids, and its polyphagy may have contributed to its global spread. The role of D. suzukii’s Wolbachia strain (wSuz) remains unconfirmed, although a mutualistic role in dealing with abiotic stress has been hypothesized. In some insect species, Wolbachia acts as a nutritional mutualist. This study explored the role of wSuz in D. suzukii adaptation to fluctuating diet regimes. To simulate a diet shift, we used Wolbachia-infected and uninfected flies, maintained on a corn-based (low-starch) or a grape-based (high-starch) diet for at least 10 generations. Then, we placed individuals from each line on one or the other diet for 30 days. The effects of Wolbachia and the diet treatments were assessed by quantifying female fecundity, egg-to-adult development time and survival, and offspring mass. The presence of Wolbachia positively affected female fecundity and offspring mass after a diet shift. Wolbachia also increased survival during larval development regardless of the diet, supporting its mutualistic role. Our results underline the role of wSuz on D. suzukii diet tolerance and performance. A better understanding of the role of symbionts in invasive species could help to improve management strategies.

The heterogeneity and complexity of symptom presentation, comorbidities and genetic factors pose challenges to the identification of biological mechanisms underlying complex diseases. Current approaches used to identify biological subtypes of major depressive disorder (MDD) mainly focus on clinical characteristics that cannot be linked to specific biological models. Here, we examined multimorbidities to identify MDD subtypes with distinct genetic and environmental factors. We leveraged dynamic Bayesian network approaches to determine a minimal set of multimorbidities relevant to MDD and identified seven clusters of disease-burden trajectories throughout the lifespan among 1.2 million participants from transnational cohorts. The clusters had clear protective- and risk-factor profiles as well as age-specific clinical courses mainly driven by inflammatory processes, and a comprehensive map of heritability and genetic correlations among these clusters was revealed. Our results can guide the development of personalized treatments for MDD based on the unique genetic, clinical and modifiable risk-factor profiles of patients.
