Understanding the Role of Environmental Transmission on COVID-19 Herd Immunity and Invasion Potential
Authors: Masud M.A , Islam Md. Hamidul , Kim Byul Nim 
Published: September 2022

AbstractCOVID-19 is caused by the SARS-CoV-2 virus, which is mainly transmitted directly between humans. However, it is observed that this disease can also be transmitted through an indirect route via environmental fomites. The development of appropriate and effective vaccines has allowed us to target and anticipate herd immunity. Understanding of the transmission dynamics and the persistence of the virus on environmental fomites and their resistive role on indirect transmission of the virus is an important scientific and public health challenge because it is essential to consider all possible transmission routes and route specific transmission strength to accurately quantify the herd immunity threshold. In this paper, we present a mathematical model that considers both direct and indirect transmission modes. Our analysis focuses on establishing the disease invasion threshold, investigating its sensitivity to both transmission routes and isolate route-specific transmission rate. Using the tau-leap algorithm, we perform a stochastic model simulation to address the invasion potential of both transmission routes. Our analysis shows that direct transmission has a higher invasion potential than that of the indirect transmission. As a proof of this concept, we fitted our model with early epidemic data from several countries to uniquely estimate the reproduction numbers associated with direct and indirect transmission upon confirming the identifiability of the parameters. As the indirect transmission possess lower invasion potential than direct transmission, proper estimation and necessary steps toward mitigating it would help reduce vaccination requirement.
General variable neighborhood search for the parallel machine scheduling problem with two common servers
Authors: Elidrissi Abdelhak , Benmansour Rachid , Sifaleras Angelo 
Published: September 2022

AbstractWe address in this paper the parallel machine scheduling problem with a shared loading server and a shared unloading server. Each job has to be loaded by the loading server before being processed on one of the available machines and unloaded immediately by the unloading server after its processing. The objective function involves the minimization of the overall completion time, known as the makespan. This important problem raises in flexible manufacturing systems, automated material handling, healthcare, and many other industrial fields, and has been little studied up to now. To date, research on it has focused on the case of two machines. The regular case of this problem is considered. A mixed integer programming formulation based on completion time variables is suggested to solve small-sized instances of the problem. Due to its $$\mathcal{NP}\mathcal{}$$

NP

-hardness, we propose two greedy heuristics based on the minimization of the loading, respectively unloading, server waiting time, and an efficient General Variable Neighborhood Search (GVNS) algorithm. In the computational experiments, the proposed methods are compared using 120 new and publicly available instances. It turns out that, the proposed GVNS with an initial solution-finding mechanism based on the unloading server waiting time minimization significantly outperforms the other approaches.
Experimental Verification and Nonlinear Dynamic Response Analysis of a Rolling Element Bearing with Localized Defects

Published: September 2022

AbstractIn this paper, the dynamic behavior of rolling element bearings with localized faults on the inner and outer rings is investigated. A nonlinear mathematical model is developed with five degrees of freedom considering rotor unbalance. In this bearing model, the nonlinearity is caused by the Hertzian contact forces and the radial internal clearance. The fourth-order Runge–Kutta technique is used to solve the coupled nonlinear equations of motion numerically. Nonlinear vibration response of the rotor and bearing housing can be obtained in both time and frequency domains. An experimental verification of the numerical model is presented where experimental measurements for defective ball bearings are compared with the numerical results. Envelope spectra of the numerical results show similar behavior to that of the measured experimental signals. A parametric analysis is conducted to investigate the effect of system parameters on the nonlinear dynamic response using time waveforms, orbit plots, frequency spectra and bifurcation diagrams. The presented results demonstrate that the dynamic response shows periodic, quasi-periodic and chaotic motions because of varying rotational speeds and defect width. The proposed model contributes toward improved design and better health monitoring of bearings in practice.
Revisional Roux-en-Y Gastric Bypass Versus Revisional One-Anastomosis Gastric Bypass After Failed Sleeve Gastrectomy: a Randomized Controlled Trial
Authors: Hany Mohamed , Zidan Ahmed , Elmongui Ehab , Torensma Bart 
Published: September 2022

Abstract

Background

High rates of revision surgery have been reported for laparoscopic sleeve gastrectomy (LSG), with weight regain (WR) as the most frequently reported cause. Roux-en-Y gastric bypass (RYGB) is the most commonly performed revision procedure, whereas one-anastomosis gastric bypass (OAGB) is a less popular approach.

Methods
A single-blinded randomized controlled trial was conducted. One hundred seventy-six patients were enrolled and randomized. After loss to follow-up, 80 patients for RYGB and 80 patients for OAGB were analyzed, with a 2-year follow-up. Patients with grade B or higher gastroesophageal reflux disease (GERD) were excluded. Early and late postoperative complications were recorded. Body mass index (BMI), percentage of excess BMI loss (%EBMIL), nutritional laboratory test results, and the resolution of associated medical problems were assessed after revision surgery.

Results
After 2 years, both groups achieved significantly lower BMI than their post-LSG nadir BMI (p < 0.001). The %EBMIL changes showed significantly faster weight loss in the OAGB group than in the RYGB at the 6-month follow-up (mean difference: 8.5%, 95% confidence interval [CI]: 0.2 to 16.9%). However, at 1-year and 2-year follow-ups, the differences were statistically insignificant (p > 0.05). Early and late complications were similar between two groups. Both groups showed improvement or resolution of associated medical problems, with no statistically significant differences after 2 years (p = 1.00).

Conclusion
Both revisional RYGB and OAGB have comparable significant weight loss effects when performed for WR after LSG. After a 2-year follow-up, both procedures were safe, with no significant differences in the occurrence of complications and nutritional deficits.

Published: September 2022

Abstract

Purpose
To identify factors associated with cancer-related self-perception after being affected by prostate cancer (PCa) and radical prostatectomy.

Subjects and methods
Men affected by PCa and radical prostatectomy were asked to choose one of 5 cancer-related identities (“patient,” “victim,” “someone who has had cancer,” “cancer survivor,” and “cancer conqueror”). Associations with clinical data, functional outcome (continence and sexual activity), and psychological factors were assessed.

Results
One thousand seven hundred seventy-two men were included. Most men perceived themselves as “someone who has had cancer” (46.8%) which was associated with no cancer recurrence (OR: 0.54 [0.36–0.81]) and low cancer-related distress (OR: 0.69 [0.53–0.89]) or “patient” (35.4%) which was associated with ongoing therapy (OR: 2.59 [1.59–4.22]) and biochemical disease recurrence (OR: 1.91 [1.28–2.85]). Self-perception, as “cancer survivor” (7.8%), “cancer conqueror” (8.2%), or “victim” (1.8%), was less common. “Cancer survivor” was associated with high perceived disease severity (OR: 2.07 [1.33–3.24]) and incontinence (1.99 [1.27–3.12]). “Cancer survivor” and “cancer conqueror” were related to high benefit finding (OR: 2.05 [1.30–3.23], OR: 1.89 [1.27–2.81], respectively); only “cancer conqueror” was associated with higher quality of life (OR: 1.38 [1.21–1.58]).

Conclusions
Self-perception in men affected by PCa can vary widely and is associated with distinct characteristics that reflect the experienced severity of the disease, therapy side effects, and psychological well-being.

Implications for Cancer Survivors
The assessment of cancer-related self-perception can give important insights when evaluating men affected by PCa who need assistance in coping with their disease.
Contrasting Trophic Niche and Resource Use Dynamics Across Multiple American Horseshoe Crab (Limulus polyphemus) Populations and Age Groups

Published: September 2022

AbstractHorseshoe crabs (Limulus polyphemus) exhibit ontogenetic and geographic variability in migratory patterns, yet the implications of movement on their resource use dynamics remain poorly understood. Here, we evaluate horseshoe crab resource use across ontogeny (instars 14–18 and adults), sex, seasons, and between two spatially distinct populations that exhibit different migratory patterns. Multi-tissue stable isotope analyses of carbon, nitrogen, and sulfur were used to examine (1) ontogenetic and sex-specific variability in the reliance of resource pools; (2) variation in isotopic niche breadth within and among populations; and (3) seasonal variability in resource use within juvenile life stages. We found evidence for subtle ontogenetic shifts in resource use, with increased contributions of phytoplankton with ontogeny, but all age groups predominantly relied on sedimentary organic matter (SOM) pools. Sex-specific differences in resource use were observed with SOM serving as the predominant source assimilated in males, while females exhibited a higher dependence on phytoplankton resource pools, indicating foraging or spatial preferences may be different between sexes. Low trophic niche overlap between adult and juvenile horseshoe crabs was evident, likely arising from differences in migratory patterns and size constraints. Within juveniles, no seasonal differences in resource use were observed, indicating that dietary patterns may remain static across temporal scales, consistent with limited dispersal of that life stage. Spatial differences in resource use were, however, observed between adult crabs likely reflecting the migratory strategies of different populations. Our results are consistent with previous evidence that horseshoe crabs are dietary generalists but provide novel insights into the linkages between movement and trophic patterns.
The “Lamprophyre Clan” Revisited
Authors: Kamvisis Ioannis , Phani Pothuri Ramesh Chandra 
Published: September 2022

Abstract
A sequential genetic diagram is proposed for lamprophyres adopting their definitions, classification, petrological and geochemical signatures from an elaborated literature survey. Based on the definition of individual lamprophyric types, the existence of “Lamprophyre clan” of rocks is supported as it was first proposed by Rock in 1991. A diagram has been created for this purpose. Characteristic examples from India and their approximate spatial distribution in the eastern Dharwar craton in particular, have also been presented.
Geodiversity, Geoheritage and Geoconservation: A Global Perspective
Authors: Kaur Gurmeet 
Published: September 2022

Abstract
In recent decades, the growing awareness and necessity of dealing with geodiversity and geoheritage has drawn the attention of the global geoscientific community to conserving and safeguarding it. As a result, the global initiatives, reinforced by the efforts of the regional and local geological communities, have led to a paradigm shift in how geodiversity (diverse geological elements) and geoheritage (geological heritage) are perceived. The efforts and actions of some nations in conserving geodiversity and geoheritage have been exemplary, while others are still in a nascent stage and a few still need to awaken. The concepts of geodiversity, geoparks, geoheritage, and geoconservation are the fruits of the efforts of many global and regional organizations. The collective efforts of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the International Union for Conservation of Nature (IUCN), Global Geoparks Network (GGN), and the International Union of Geological Sciences (IUGS) have brought the attention of the global geoscientific community, policymakers and governments of almost all nations to ponder the issues of geodiversity and geoheritage. These globally recognised organisations have been at the forefront and their initiatives have permitted the conservation of some significant geological heritage and have demonstrated that they can pave a new path for more sustainable development. These organisations have worked in tandem for the past few decades and have been successful in identifying and designating some of the outstanding and geologically significant sites/geosites as ‘Natural World Heritage Sites’, ‘UNESCO Global Geoparks’. The novel ideas and statutes defining global designation criteria and protocols by these organisations are there to enthuse and encourage earth scientists, policymakers, the public, and governments of all nations to frame their own national and local statutes for the identification and conservation of outstanding national geoheritage and to further integrate them with the international organisations for global designations.
River Aquifer Interaction Modeling for the Waterlogged Aquifer and Sustainable Groundwater Irrigation along River Flood Plain
Authors: Singh Mrinal Kumar , Ghosh Susmita 
Published: September 2022

Abstract
The river aquifer interaction model was developed for the waterlogged-alluvial aquifer to address the issues of the lower river leakage and higher aquifer discharge in the waterlogged groundwater system. The developed model was simulated and calibrated for the 15 years simulation period (2006-2020). From the model study, it is observed that river aquifer interaction changes seasonally, river leakages to the aquifer in the monsoon period and aquifer discharges to the river in the rest period. From the analysis, it is visualized that the monthly variation in river aquifer interaction majorly depends on the river stage. From the analysis, it also concluded that the value of river leakage is low as compared to aquifer discharge caused due to aquifer waterlogging. The model was further applied to reduce the waterlogged area to a certain degree by introducing sustainable groundwater irrigation from the waterlogged aquifer during the dry/Rabi season. Thus, the fraction of uncultivated land near the river flood plain converted as agricultural land. Sustainability is achieved by considering the three scenarios to unaltering the river aquifer interaction seasonally. The three scenarios are introducing groundwater irrigation to convert (i) 25%, (ii) 50% and (iii) 75% of the uncultivated land to agricultural land. It is revealed from the study that the sustainable proposed scenario is where the agricultural land equals to 75% of uncultivated land. The proposed methodology has been illustrated in the alluvial flood plain of the Barak river in Cachar, Assam, India.

Published: September 2022

Abstract
The current study deals with the application of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) multispectral data to delineate bauxite deposits over Mainpat plateau, Surguja district, Chhattisgarh, India. Application of specific band combinations help to delineate bauxite in the (SWIR) region (2.16-2.33 μm) and visible near infrared (VNIR) band (0.4–1.0 μm) of multispectral ASTER data. Various image processing techniques like atmospheric correction, minimum noise fraction, pixel purity index, n-dimensional visualiser, and spectral angle mapper were applied to ASTER image to delineate bauxite rich zones. The pure pixels were differentiated from the mixed pixels using pixel purity index which were further subjected to n-dimensional visualiser to identify the target end-members. The presence of bauxite was confirmed by comparing the spectral signatures of end-members with in-built spectral plots of United States Geological Survey spectral libraries and categorized as bauxite and ferruginous bauxite. Finally, the end-members were categorised as bauxite and ferruginous bauxite and mapped using spectral angle mapper. The result obtained was further compared with the lithological map provided by Geological Survey of India for accuracy. Then XRF analysis was carried out for the collected samples to confirm the presence of bauxite and ferruginous bauxite. Geochemical analysis also categorized the samples as bauxite and ferruginous bauxite that added accuracy to the results obtained from remote sensing technique. This study might be considered as a time saving eco-friendly exploitation of natural resources and finally the potential of multispectral ASTER data for mapping mineral resources.
How will an increase in organic agricultural area affect land use in Germany?
Authors: Rasche Livia , Steinhauser Jan 
Published: September 2022

AbstractOrganic agriculture is an attractive land use alternative to conventional farming in terms of environmental and biodiversity protection. The official German target is a 30% share of organic agricultural area by 2030, while German stakeholders consider 24% realistic and 44% desirable. It is unclear how such a shift may affect the food and land use system. We use data from a crop/pest model to estimate yield differences between conventional and organic systems, and the FABLE accounting tool to assess changes in indicators like calories available per person and day, and the extent of cropland, pasture and area where natural processes predominate. We investigate how an increase in organic agricultural area may affect these indicators up to 2050, and if adaptation measures may become necessary to ameliorate the potential pressure to expand cropland or raise import rates. The results show that if organic agricultural area is increased, there will be a calorie deficit of 7–80 kcal per person and day, corresponding to 1000–5000 km2 of missing cropland. The deficit will disappear without any changes to the system by 2045 at the latest due to demographic and technological development. No additional cropland at all would be required if crop productivity increased at a higher rate than observed today, and an additional 600,000 ha could be freed even with a 30% share of organic agriculture. A higher share of organic agriculture is thus a realistic target for Germany, but technological advancements should accompany the transformation to minimize cropland demand.
Analysis of runoff variation and driving mechanism in Huangfuchuan River Basin in the middle reaches of the Yellow River, China
Authors: Huang Xin , Qiu Lin 
Published: September 2022

AbstractTo address the prominent problem of declining runoff in many rivers around the world, studying the law of runoff change and attribution analysis is very important for the planning and management of watershed water resources and has practical significance for solving the imbalance between supply and demand of watershed water resources and maintaining the healthy development of rivers. Three commonly used coupled water-energy balance equations based on Budyko hypothesis are selected to estimate the elasticity coefficient of runoff change to each driving factor, and the contribution rate of different factors to runoff change in the study area is quantified by the total differential method and the complementary method, respectively. The results show that the runoff of Huangfuchuan River basin showed a significant decreasing trend from 1954 to 2015, and the runoff mutation points were 1979 and 1996; in the alteration period I (1979–1996), precipitation was the main factor leading to the runoff reduction in Huangfuchuan River basin, followed by the influence of underlying surface; the contribution rate of underlying surface to runoff alterations ranged from 63.7% to 65.46%; the impact of potential evapotranspiration was slightly smaller. In the alteration period II (1997–2015), the underlying surface played a dominant role in runoff reduction of Huangfuchuan River basin. The contribution rate of the underlying surface to runoff change ranged from 80.21% to 86.34%, followed by precipitation, and the potential evapotranspiration had the least impact. The impact of human activities on the whole watershed increased with the passage of time. The land use change, the overall increase of NDVI (vegetation cover) and the construction of water conservation projects are important reasons for the reduction of runoff in Huangfuchuan River basin.
Analyzing social media for measuring public attitudes toward controversies and their driving factors: a case study of migration

Published: September 2022

AbstractAmong other ways of expressing opinions on media such as blogs, and forums, social media (such as Twitter) has become one of the most widely used channels by populations for expressing their opinions. With an increasing interest in the topic of migration in Europe, it is important to process and analyze these opinions. To this end, this study aims at measuring the public attitudes toward migration in terms of sentiments and hate speech from a large number of tweets crawled on the decisive topic of migration. This study introduces a knowledge base (KB) of anonymized migration-related annotated tweets termed as (MGKB). The tweets from 2013 to July 2021 in the European countries that are hosts of immigrants are collected, pre-processed, and filtered using advanced topic modeling techniques. BERT-based entity linking and sentiment analysis, complemented by attention-based hate speech detection, are performed to annotate the curated tweets. Moreover, external databases are used to identify the potential social and economic factors causing negative public attitudes toward migration. The analysis aligns with the hypothesis that the countries with more migrants have fewer negative and hateful tweets. To further promote research in the interdisciplinary fields of social sciences and computer science, the outcomes are integrated into MGKB, which significantly extends the existing ontology to consider the public attitudes toward migrations and economic indicators. This study further discusses the use-cases and exploitation of MGKB. Finally, MGKB is made publicly available, fully supporting the FAIR principles.
