Published: November 2022

AbstractIn the past few decades, the Loess Plateau has undergone large-scale underlying surface changes. A large number of soil and water conservation measures have been constructed, which have affected the runoff and sediment status in the region. How runoff and sediment status respond to underlying surface changes is the key to quantitatively evaluate the effect of water and sediment reduction by soil and water conservation measures in flood events. We selected check dams and terraced fields, which account for a large proportion of soil and water conservation measures as assessment objects and constructed a runoff-sediment model combining traditional physical mechanisms and deep learning to simulate and analyze flood events in a typical basin of the Loess Plateau. The results show that the simulation effect of model is good. The relative error of runoff is within 15%, average Nash–Sutcliffe efficiency coefficient is 0.86, and the relative error of soil loss is within 30%. Check dam system in the Chenggou River Basin can intercept 55.61% of the runoff and 47% of the soil loss in the basin on average, and terracing can reduce the runoff by 10.54% and the soil loss by 33.8%.

Published: November 2022

AbstractA low-cost locally available agricultural waste-based Anchote peel adsorbent was studied to remove the methyl orange (MO) dye from wastewater which was created at laboratory conditions. The adsorbent was characterized by Fourier infrared and x-ray powder diffraction spectroscopic techniques. The adsorption capacity of the proposed adsorbent was investigated using the batch adsorption method. The best performance was achieved after careful optimization of experimental parameters such as adsorbent dose (0.4 g), initial dye concentration (70 mg/L), contact time (140 min), pH of the solution (8.0), and temperature (40 °C), respectively. The removal of MO from water using anchote peel adsorbent achieved a removal efficiency of 94.47% following the pseudo-second-order kinetic model, Freundlich isotherm, and chemisorption mechanism, respectively. The adsorbent showed heterogeneous surfaces and the adsorption of MO was thermodynamically spontaneous. Furthermore, the present results reveal that Anchote peel adsorbent is promising in future for the removal of organic dyes and other contaminants like toxic heavy metals from water and wastewater.

Published: November 2022

AbstractChanges in climate drivers are projected to have a considerable impact on coastal freshwater supply and demand systems in future decades. The utilization of rainfall in coastal regions to secure sufficient freshwater to satisfy the rising demands of socioeconomic development has become a critical duty for decision-makers. This article assesses the present state of rainwater utilization in the water resources system for the coastal regions in Egypt. Volumes of annual rainfall that precipitate in 11 coastal Egyptian cities are estimated using ArcGIS maps and the run off rational equation. A future vision of using the estimated rainwater harvesting (RWH) from urban coastal cities in the water resources system is presented. Several scenarios are suggested and analyzed for using these volumes of water in the total water resources system in Egypt and also in the water resources system corresponding to each selected coastal governorate. The results indicated that over the areas under consideration, the annual maximum total amount of precipitation is limited to 1.8 km3. However, it is anticipated that 1 km3 of the average annual quantity of rainfall water is efficiently used for agriculture. These findings are intended to help managers, planners, and decision-makers to choose locations, invest in water resources, and employ RWH as a substitute for traditional water sources.

Abstractβ-Ga2O3 nanocrystals have been successfully obtained by the high-energy ball milling method. The obtained nanocrystalline powders have been characterized using X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and luminescent spectroscopy. X-ray diffraction patterns show a single gallium oxide structure formed in the milling process with a small amount of α-Ga2O3 phase. The grains of irregular shape were identified with the TEM technique. HRTEM images confirmed the formation of the β-Ga2O3 nanocrystals with a size distribution of 50–80 nm. Three luminescence bands peaked at about 2.52, 2.91, and 3.26 eV were observed in photoluminescence spectra. The gradual blue shift of the emission maxima at the excitation in the fundamental absorption edge under the different milling conditions was detected.
Classification by Principal Component Regression in the Real and Hypercomplex Domains

Published: November 2022

AbstractLinear regression is a simple and widely used machine learning algorithm. It is a statistical approach for modeling the relationship between a scalar variable and one or more variables. In this paper, a classification by principal component regression (CbPCR) strategy is proposed. This strategy depends on performing regression of each data class in terms of its principal components. This CbPCR formulation leads to a new formulation of the Linear Regression Classification (LRC) problem that preserves the key information of the data classes while providing more compact closed-form solutions. For the sake of image classification, this strategy is also extended to the 4D hypercomplex domains to take into account the color information of the image. Quaternion and reduced biquaternion CbPCR strategies are proposed by representing each channel of the color image as one of the imaginary parts of a quaternion or reduced biquaternion number. Experiments on two color face recognition benchmark databases show that the proposed methods achieve better accuracies by a margin of about 3% over the original LRC and like methods.
Photocatalytic Performance of Organically Templated Cr-Doped Co3O4 in Remediation of Industrial Wastewater: Effect of Order–Disorder in the Lattice
Authors: Shalaby Nasser H. 
Published: November 2022

AbstractIn photocatalysis, the optical properties and surface parameters significantly affect the catalytic performance. To engineer the optical properties and textural structure, Cr and p-phenylene diamine (PDA) were utilized as dopant and textural structure regulator, respectively. A series of Cr-doped Co3O4 with dopant percentages of 0, 1, 3, and 5, templated PDA at a fixed ratio of 5%, and another un-templated sample with a dopant ratio of 5% were prepared. The co-precipitation method was applied in swift and innovative procedures, where a calculated amount of NaOH was used as a precipitant. The optical properties, dopant concentration quenching, and surface parameters are strongly affected by the order–disorder in the lattice and dopant concentration. The lattice regularity affects the optical properties and the surface parameters along with the dopant concentration. The photocatalysts were evaluated in the disposal of organic pollutants in a representative sample of wastewater collected from different industrial activities. The function of another function was applied to monitor the pollutants' disposal, taking the total organic carbon (TOC) as a function of the pollutants' concentration and the photometric absorbance as a function of the TOC. The kinetic investigation exhibited the significant role of the pore system on the reaction rate.
Spherical Bessel functions and critical lengths
Authors: Carnicer J. M. , Mainar E. , Peña J. M. 
Published: November 2022

AbstractThe critical length of a space of functions can be described as the supremum of the length of the intervals where Hermite interpolation problems are unisolvent for any choice of nodes. We analyze the critical length for spaces containing products of algebraic polynomials and trigonometric functions. We show the relation of these spaces with spherical Bessel functions and bound above their critical length by the first positive zero of a Bessel function of the first kind.

Abstract
Background
CXCL11 has been reported to be up-regulated in hepatocellular carcinoma (HCC) tissues and cancer-associated fibroblasts (CAFs), and CAF-secreted CXCL11 has been found to promote HCC cell proliferation and migration. Knowledge on how CAFs promote HCC progression is imperative for the future design of anti-tumor drugs addressing the high rates of disease recurrence. Herein, we propose a mechanism by which LINC00152 positively regulates CXCL11 expression and, subsequently, HCC cell phenotypes and growth characteristics via miR-205-5p in CAFs.

Methods
The expression of LINC00152, miR-205-5p in HCC/non-cancerous tissues, CAFs/NFs and HCC cell lines was determined by RT-qPCR. The CXCL11 expression and secretion were determined by westernblot and ELISA. Different expressions of LINC00152, CXCL11 and miR-205-5p in CAFs were achieved by transfection with corresponding overexpression/knockdown vectors or mimics/inhibitor. The interactions among LINC00152, miR-205-5p and CXCL11 were confirmed by FISH, luciferase, AGO2 and RNA-pulldown assays. Transwell, colony formation and MTT assays were performed to assess the role of CAFs conditioned medium (CM) in HCC cell phenotype. BALB/c nude mice xenografts were used to determine the role of CAFs on HCC growth in vivo.

Results
We found that in vitro, CM from CAFs transfected with sh-LINC00152 dramatically suppressed HCC cell viability, colony formation and migration, and that CM from CAFs transfected with miR-205-5p inhibitor (CAF-CM (miR-205-5p inhibitor)) exerted opposite effects on HCC cell phenotypes. Exogenous overexpression of CXCL11 in CAFs or CAF-CM (miR-205-5p inhibitor) could partially attenuate the effects of LINC00152 knockdown. In contrast, CM from CAFs transfected with LINC00152 dramatically increased HCC cell viability, colony formation and migration, and CM from CAFs transfected with miR-205-5p mimics (CAF-CM (miR-205-5p mimics)) exerted opposite effects on HCC cell phenotypes. Knockdown of CXCL11 in CAFs or CAF-CM (miR-205-5p mimics) could partially attenuate the effects of LINC00152 overexpression. In vivo, LINC00152 knockdown in CAFs inhibited tumor growth in a mouse model, which could be reversed by CXCL11 overexpression in CAFs. Mechanistically, we found that LINC00152 could act as a ceRNA to counteract miR-205-5p-mediated suppression on CXCL11 by directly binding to miR-205-5p and the 3’UTR of CXCL11.

Conclusion
Our data indicate that a LINC00152/miR-205-5p/CXCL11 axis in HCC CAFs can affect the proliferative and migrative abilities of HCC cells in vitro and HCC tumor growth in vivo.
Influence of the geometry on the fatigue strength of welded joints using the effective notch stress approach
Authors: Lippardt Sven 
Published: November 2022

AbstractUsing the example of a cruciform joint, this study enquires into the relationship between the geometry of weld (the wall thickness of base metal plates, thickness of weld and weld penetration depth) and the fatigue strength of weld joint using the finite element method. It is assumed that the effective notch stress approach can be used to determine a FAT class for dimensioning the connection with the nominal stress approach. Filled throat thickness and weld penetration depth or the geometry of weld root were found to have a strong influence on the fatigue strength of a welded joint. When using the effective notch stress approach, the exact geometry of the calculated weld seam must be known and should be modelled accordingly. It was also found that with thin-walled welds, the effect of wall thickness produces a significant deviation between the load capacity calculated with the effective notch stress approach (effect of wall thickness up to 100%), and with the nominal stress approach (effect of wall thickness max. 10%). At the end, a proposal will be made on how thin-walled welds can be dimensioned to facilitate the use of the same thickness factor for both the notch and nominal stress approaches.

Abstract
Purpose
Gastrinoma with Zollinger–Ellison syndrome (ZES) may occur sporadically (Sp) or as part of the inherited syndrome of multiple endocrine neoplasia 1 (MEN-1). Data comparing Sp and MEN-1/ZES are scanty. We aimed to identify and compare their clinical features.

Methods
Consecutive patients with ZES were evaluated between 1992 and 2020 among a monocentric Italian patient cohort.

Results
Of 76 MEN-1 patients, 41 had gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN), 18 of whom had ZES; of 320 Sp-GEP-NEN, 19 had Sp-ZES. MEN-1/ZES patients were younger (p = 0.035) and the primary MEN-1/ZES gastrinoma was smaller than Sp-ZES (p = 0.030). Liver metastases occurred in both groups, but only Sp-ZES developed extrahepatic metastases. 13 Sp-ZES and 8 MEN-1/ZES underwent surgery. 8 Sp-ZES and 7 MEN-1/ZES received somatostatin analogs (SSAs). Median overall survival (OS) was higher in MEN-1/ZES than in Sp-ZES (310 vs 168 months, p = 0.034). At univariate-logistic regression, age at diagnosis (p = 0.01, OR = 1.1), G3 grading (p = 0.003, OR = 21.3), Sp-ZES (p = 0.02, OR = 0.3) and presence of extrahepatic metastases (p = 0.001, OR = 7.2) showed a significant association with OS. At multivariate-COX-analysis, none of the variables resulted significantly related to OS. At univariate-logistic regression, age (p = 0.04, OR = 1.0), size (p = 0.039, OR = 1.0), G3 grade (p = 0.008, OR = 14.6) and extrahepatic metastases (p = 0.005, OR = 4.6) were independently associated with progression-free survival (PFS). In multivariate-COX-analysis, only extrahepatic metastases (p = 0.05, OR = 3.4) showed a significant association with PFS. Among SSAs-treated patients, MEN-1/ZES showed better PFS (p = 0.0227). After surgery, the median PFS was 126 and 96 months in MEN-1 and Sp, respectively.

Conclusion
MEN-1/ZES patients generally show better OS and PFS than Sp-ZES as well as better SSAs response.
Make or break the loop: a cross-practitioners review of glass circularity
Authors: Geboes Esther , Galle Waldo , De Temmerman Niels 
Published: November 2022

AbstractEnd-of-life insulating glass units (IGUs) continue to follow a linear, wasteful path from renovation and demolition sites into landfills or low-value recycling. To get one step closer to the question of how to close the glass loop, this exploratory research outlines a cross-practitioners review of glass circularity in conventional Flemish and Brussels practices. A series of semi-structured interviews with network actors and an extensive literature study is conducted to identify existing and missing circular practices and to pinpoint the key barriers and opportunities. In general, the circular strategies repurpose and open-loop recycling of end-of-life IGUs are successfully applied in Flemish and Brussels construction practices. Repair, reuse, and closed-loop recycling remain unexplored. The main barriers are the lack of collaboration, logistic and labour costs to collect end-of-life IGUs, its complex disassembly, the lack of legal incentives and the conservativeness of the construction sector. Case studies, the high recycling potential and the scale of projects are found to be the main opportunities for glass circularity. The cross-practitioners’ insights in this paper contribute to close the glass loop and to further development and up-scaling of circular strategies.
$$\Delta $$-Conformity: multi-scale node assortativity in feature-rich stream graphs
Authors: Citraro Salvatore , Milli Letizia , Cazabet Rémy , Rossetti Giulio 
Published: November 2022

AbstractMulti-scale strategies to estimate mixing patterns are meant to capture heterogeneous behaviors among node homophily, but they ignore an important addendum often available in real-world networks: the time when edges are present and the time-varying paths that edges form accordingly. In this work, we go beyond the assumption of a static network topology to propose a multi-scale, path- and time-aware node homophily estimator specifically tied for feature-rich stream graphs: $$\Delta $$
Δ
-Conformity. Our measure can capture the homogeneous/heterogeneous tendency of nodes’ connectivity along a period of time $$\Delta $$
Δ
starting from a given moment in time. Results on face-to-face interaction networks suggest it is possible to track changes in social mixing behaviors that coincide with contextually reasonable everyday patterns, e.g., medical staff disassortative behavior when exposed to patients. In a different domain, that of the Bitcoin Transaction Network, we capture relationships between the quantity of money sent from (and to) different categories/continents and their respective mixing trends over time. All these insights help us to introduce $$\Delta $$
Δ
-Conformity as a suitable solution for understanding temporal homophily by capturing the mixing tendency of entities embedded in fine-grained evolving contexts.
On merge trees and discrete Morse functions on paths and trees
Authors: Brüggemann Julian 
Published: November 2022

AbstractIn this work we answer an open question asked by Johnson–Scoville. We show that each merge tree is represented by a discrete Morse function on a path. Furthermore, we present explicit constructions for two different but related kinds of discrete Morse functions on paths that induce any given merge tree. A refinement of the used methods allows us to define notions of equivalence of discrete Morse functions on trees which give rise to a bijection between equivalence classes of discrete Morse functions and isomorphism classes of certain labeled merge trees. We also compare our results to similar ones from the literature, in particular to work by Curry.
A Novel Social Network Group Decision-Making Method in a Quantum Framework
Authors: Cai Mei , Jian Xinglian , Hong YuanYuan , Xiao Jingmei , Gao Yu , Hu Suqiong 
Published: November 2022

AbstractSocial networks (SNs) have become popular as a medium for disseminating information and connecting like-minded people. They play a central role in decision-making by correlating the behaviors and preferences of connected agents. However, it is difficult to identify social influence effects in decision-making. In this article, we propose a framework of how to describe the uncertain nature of the social network group decision-making (SN-GDM) process. Social networks analysis (SNA) and quantum probability theory (QPT) are combined to construct a decision framework considering superposition and interference effects in SN-GDM scenarios. For the first time, we divide interference effects into symmetry and asymmetry. We construct an influence diagram, which is a quantum-like Bayesian network (QLBN), to model group decisions with interactions. We identify symmetry interference terms from Shapley value and asymmetry interference terms from trust value, respectively. The probability of an alternative is calculated through quantum probability theory in our influence diagram. The combination of QLBN model and social network could gain an understanding of how the group preferences evolve within SN-GDM scenarios, and provide new insights into SNA. Finally, an overall comparative analysis is performed with traditional SNA and other quantum decision models.
A Narrative from the Margins: Community and Agency during the US Occupation of the Dominican Republic, 1916–1924
Authors: Rodríguez Alexa 
Published: December 2022

AbstractWhile US and Dominican officials have traditionally received credit for the expansion of the public school system during the US military occupation of the Dominican Republic from 1916 to 1924, this article offers an alternative account by focusing on the role of guardians, or caretakers, in supporting and creating schools in this period. Drawing from sources from the Department of Public Instruction in the Dominican Republic and analyzing them “against the archival grain,” I argue that Dominican guardians were pivotal to the expansion of the Dominican school system and key actors in shaping the educational landscape during this period. Not only did guardians construct and maintain most of the schools opened during the US occupation, but they also shaped school policy. Most significantly, through their grassroots efforts, guardians and other volunteers ensured that schools in the Dominican Republic continued to operate during the financial crisis of 1921 that bankrupted the school system.

Published: December 2022

AbstractSoft magnetic robots have attracted tremendous interest owning to their controllability and manoeuvrability, demonstrating great prospects in a number of industrial areas. However, further explorations on the locomotion and corresponding deformation of magnetic robots with complex configurations are still challenging. In the present study, we analyse a series of soft magnetic robots with various geometric shapes under the action of the magnetic field. First, we prepared the matrix material for the robot, that is, the mixture of silicone and magnetic particles. Next, we fabricated a triangular robot whose locomotion speed and warping speed are approximately 1.5 and 9 mm/s, respectively. We then surveyed the generalised types of robots with other shapes, where the movement, grabbing, closure and flipping behaviours were fully demonstrated. The experiments show that the arching speed and grabbing speed of the cross-shaped robot are around 4.8 and 3.5 mm/s, the crawling speed of the pentagram-shaped robot is 3.5 mm/s, the pentahedron-shaped robot can finish its closure motion in 1 s and the arch-shaped robot can flip forward and backward in 0.5 s. The numerical simulation based on the finite element method has been compared with the experimental results, and they are in excellent agreement. The results are beneficial to engineer soft robots under the multi-fields, which can broaden the eyes on inventing intellectual devices and equipment.
