Published: October 2022

Abstract
Ferrate salt is a powerful oxidant for dye degradation. This work demonstrates a new method for degrading dyes containing Fe(vi) by synthesizing NaOCl from the electrolysis of table salt. NaOCl is then reacted with Fe(OH)3 in an alkaline condition to form ferrate. Electrolysis of table salt was successfully carried out using platinum as an anode and zinc as a cathode. The obtained ferrate was characterized by using Fourier transform infrared, UV-Vis, and X-ray diffraction spectroscopy. The ferrate solution has a maximum wavelength of 505 nm with a characteristic purple color. Furthermore, the ferrate produced was utilized to remove methylene blue (MB), remazol black blue (RBB), and methyl orange (MO) dyes with varying contact times. The degraded dyes were then analyzed using LC/MS. The results showed that ferrate was effective to remove dyes with an optimum contact time of 60 min that follows an order one reaction. In this study, MB showed a percent degradation close to 100% with the fastest decolorization rate compared with MO and RBB. This research provides new insights into the benefits of table salt as a base material for NaOCl through electrolysis for synthesizing ferrate, used in dye removal applications.
Thermally conductive h-BN/EHTPB/epoxy composites with enhanced toughness for on-board traction transformers
Authors: Yuan Shuai , Zhou Lijun , Chen Tiandong , Wang Dongyang , Wang Lujia 
Published: October 2022

AbstractThe dry-type on-board traction transformer (DOBTT) has the characteristics of huge heat generation and high heat dissipation requirements, so it has higher requirements for heat dissipation performance of epoxy resin (EP) insulation. However, the toughness of the existing high thermal conductivity EP composite after being modified by inorganic particles is greatly reduced, and it is very easy to crack under the occasion of frequent vibration such as electric multiple units or electric locomotives, so it cannot be directly applied to the DOBTT. In this article, the composite using h-BN to improve the thermal conductivity, and epoxidized hydroxy-terminated polybutadiene (EHTPB) liquid rubber to improve the toughness was prepared. After characterization and testing, it was found that when the EHTPB content was between 10 and 15 phr, the elongation at break of the EP/h-BN/EHTPB composite could be increased by 47.9% and the impact strength could be increased by 47.8% compared with that without EHTPB. The thermal and electrical performances were still satisfactory, which has a potential in application of on-board electrical equipment.

Published: October 2022

Abstract
This article mitigates the challenges of previously reported literature by reducing the operating cost and improving the performance of network. A genetic algorithm-based tabu search methodology is proposed to solve the link capacity and traffic allocation (CFA) problem in a computer communication network. An efficient modern super-heuristic search method is used to influence the fixed cost, delay cost, and variable cost of a link on the total operating cost in the computer communication network are discussed. The article analyses a large number of computer simulation results to verify the effectiveness of the tabu search algorithm for CFA problems and also improves the quality of solutions significantly compared with traditional Lagrange relaxation and subgradient optimization algorithms. The experimental results show that with the increase of the weighted coefficient of variable cost, the proportion of variable cost in the total cost increases from 10 to 35%. The growth is relatively slow, and the fixed cost is still the main component. In addition, due to the increase in the variable cost, the tabu search algorithm will also choose the link with large luxury to reduce the variable cost, which makes the fixed cost slightly increase, while the network delay cost and average delay slightly decrease. The proposed method, when compared with the genetic algorithm, has more advantages for large-scale or heavy-load networks.
An adaptive RNN algorithm to detect shilling attacks for online products in hybrid recommender system
Authors: Chopra Akanksha Bansal , Dixit Veer Sain 
Published: October 2022

Abstract
Recommender system (RS) depends on the thoughts of numerous users to predict the favourites of potential consumers. RS is vulnerable to malicious information. Unsuitable products can be offered to the user by injecting a few unscrupulous “shilling” profiles like push and nuke attacks into the RS. Injection of these attacks results in the wrong recommendation for a product. The aim of this research is to develop a framework that can be widely utilized to make excellent recommendations for sales growth. This study uses the methodology that presents an enhanced clustering algorithm named as modified density peak clustering algorithm on the consumer review dataset to ensure a well-formed cluster. An improved recurrent neural network algorithm is proposed to detect these attacks in hybrid RS, which uses the content-based RS and collaborative filtering RS. The results are compared with other state of the art algorithms. The proposed method is more suitable for E-commerce applications where the number of customers and products grows rapidly.
Morphological redescription, phylogenetic position, and distribution of the near threatened cavy Microcavia shiptoni (Thomas, 1925), with a key for the living species of Microcavia
Authors: Teta Pablo , Jayat Pablo , Ortiz Pablo E. , D’Elía Guillermo 
Published: October 2022

Abstract
The genus Microcavia includes six species of terrestrial, medium-sized, living cavies that occupy arid to semiarid environments at both high and low elevations in western and southern South America. Among these, Microcavia shiptoni is one of the least known species, being recorded only at two isolated localities from northwestern Argentina. Genetic information and a detailed morphological characterization are lacking for this elusive species. In this work, we start filling these gaps by including M. shiptoni in a phylogenetic analysis based on mitochondrial DNA sequences that includes five of the six currently recognized species and place M. shiptoni as sister to M. niata in a clade of highland species. In addition, using both qualitative and quantitative morphological traits, we provided an emended diagnosis for this taxon and a key for the living species of the genus. Finally, we present, the first notes on the natural history of this species.
Formen des Vergessens bei Tacitus
Authors: Schulz Verena 
Published: October 2022

Abstract
Tacitus understands himself as a historiographer who writes against forgetting. This essay examines how Tacitus conceives of forgetting and how he depicts processes of forgetting. (1) First I will introduce forgetting as an important research theme in modern memory studies. Research on forgetting can help us to understand transformations in the collective memory of modern and ancient social groups. (2) In Tacitus’ works about Roman imperial history forgetting stands out as a crucial topic. (3) When analysing processes of forgetting in the Annals, the Histories and the Agricola, we can distinguish different forms of forgetting (such as ‘automatic forgetting’ and ‘directed forgetting’) as well as certain methods that Tacitus depicts as supporting or impeding forgetting. I will focus on ‘removing’ as an ambivalent method of forgetting, and on ‘writing’, which is central to Tacitus’ concept of the historiographer. This analysis of Tacitus’ works reveals that his ideas on forgetting are highly relevant to the twenty-first century. Tacitus’ age, like our own, was one of dramatic societal change, in which social frames are transformed, while the objects of collective memory are questioned and reevaluated.
Jesus’ Socratic Trial and Pilate’s Confession in Nonnus’ Paraphrasis of St John’s Gospel
Authors: Lefteratou Anna 
Published: October 2022

AbstractThis article argues that theParaphrasis of St John’s Gospelby Nonnus offers a response to late antique concerns as to why the salvific message of Jesus failed to be recognised by authorities of the Roman Empire in the Gospels. By reworking the portrait of Pilate found in John’s Gospel, Nonnus transforms the governor into an unambiguously late antiquepepaideumenos,one who ultimately participates in the promulgation of Christian salvation and truth. The analysis shows that Nonnus accomplishes this portrait through the use of Homeric parallels and allusions to Plato’sApology of Socrates, which transform Jesus’ trial before Pilate from John 18 into a philosophical dialogue about justice, kingship, and truth. The poem invites its late antique audience to better identify with Pilate and to see his inscription of the title (titulus) on Jesus’ cross as an early gentile confession of faith, ultimately making Pilate into an apostleavant-la-lettreand rehabilitating the role of Rome vis-à-vis Christianity for late antique audiences.This work is part of a project on the reception of John’s Gospel in Late Antiquity under the direction of Prof. Michele Cutino and his research group, GIRPAM, at the Faculté de théologie catholique, Université de Strasbourg.
Dual-band bound states in the continuum based on hybridization of surface lattice resonances
Authors: Du Xiang , Xiong Lei , Zhao Xueqian , Chen Shuai , Shi Jianping , Li Guangyuan 
Published: October 2022

Abstract
We propose and experimentally demonstrate a novel strategy to achieve dual-band symmetry-protected bound states in the continuum (BICs) in silicon metasurfaces. This strategy is based on the hybridization of Mie surface lattice resonances (SLRs) in periodic silicon bipartite nanodisk arrays, of which the central nanodisk displaced from the center of the unit cell. We show that dual-band electric quadrupole and magnetic dipole BICs can be supported in such a system, and transfer to quasi-BICs with ultrahigh measured quality factors up to 1240 at the Γ point. Taking advantage of the SLR characteristics, we show that the spectral separation and the quality factors of these two quasi-BICs can be conveniently tuned by varying the nanodisk diameter or the lattice period. Making use of these dual-band quasi-BICs, we numerically obtain bulk sensitivities above 480 nm/RIU and high figures of merit up to 1200. We also show that when the central nanodisk is not displaced but has different diameter, the silicon bipartite nanodisk array supports an electric dipole BIC that was referred to as subradiant SLR in the literature. Our work provides a new approach for realizing and tuning dual-band BICs, and the obtained ultrahigh-Q quasi-BICs can find potential applications in nonlinear optics, multimodal lasing, and optical sensing.

Published: October 2022

Abstract
In this article, aiming at the problems of low mechanical properties and the unstable structure of the binder in inorganic artificial stone, performance improvements were studied. The effects of 12 materials of blast-furnace slag (BFS), fly ash (FA), and kaolin on the properties and microstructure of inorganic binders were systematically studied and analyzed. As a result, the compressive strength of BFS-2, FA-1, and FA-2 binder was increased by 10.0, 6.0, and 1.5%, and the flexural strength was increased by 44.8, 79.2, and 1.3%, respectively. It was worth noting that BFS and FA could effectively promote hydration reactions due to active materials and boost the growth of C–S–H and CH, leading to the inorganic binder forming a stable structure. Thus, this work systematically designs and prepares inorganic binders with high compressive strength and excellent flexural strength. This reveals how inorganic materials affect the properties of inorganic binders on the microstructure and offer a new idea for the development of this field.

Published: October 2022

Abstract
The present study details the green synthesis of silver nanoparticles using clove oil as a reducing and stabilizing agent. Cationic, anionic, nonionic and zwitterionic surfactants were introduced to study the change in size, shape, and morphology of nanoparticles. The nanoparticles were characterized using different techniques. The nanoparticles had shown specific surface Plasmon resonance band with absorbance between 380 and 385 nm. The X-ray diffraction study revealed that the nanoparticles are composed of spherical cubic crystals with average size between 136 and 180 nm while Dynamic Laser scattering (DLS) studies revealed an effective diameter of 82 nm and polydispersity index of 0.005. Thermogravimetric analysis suggested that the particles are stable even at 600 °C. All the samples presented good antibacterial and antifungal efficacies against Staphylococcus aureus, Klebsiella pneumonia and Candida albicans and good catalytic activities for the degradation of fast green and Allura red dyes. Further, thin edible films of the nanoparticles were prepared using sodium alginate for food preservation. The films were coated on fruits and vegetables for extending their shelf life to cope with demand and supply gap.
A General Framework for Inferring Bayesian Ideal Observer Models from Psychophysical Data

Published: October 2022

AbstractA central question in neuroscience is how sensory inputs are transformed into percepts. At this point, it is clear that this process is strongly influenced by prior knowledge of the sensory environment. Bayesian ideal observer models provide a useful link between data and theory that can help researchers evaluate how prior knowledge is represented and integrated with incoming sensory information. However, the statistical prior employed by a Bayesian observer cannot be measured directly, and must instead be inferred from behavioral measurements. Here, we review the general problem of inferring priors from psychophysical data, and the simple solution that follows from assuming a prior that is a Gaussian probability distribution. As our understanding of sensory processing advances, however, there is an increasing need for methods to flexibly recover the shape of Bayesian priors that are not well approximated by elementary functions. To address this issue, we describe a novel approach that applies to arbitrary prior shapes, which we parameterize using mixtures of Gaussian distributions. After incorporating a simple approximation, this method produces an analytical solution for psychophysical quantities that can be numerically optimized to recover the shapes of Bayesian priors. This approach offers advantages in flexibility, while still providing an analytical framework for many scenarios. We provide a MATLAB toolbox implementing key computations described herein.
Chronic Intermittent Ethanol Exposure Dysregulates Nucleus Basalis Magnocellularis Afferents in the Basolateral Amygdala

Published: October 2022

AbstractNucleus basalis magnocellularis (NBM) cholinergic projections to the basolateral amygdala (BLA) regulate the acquisition and consolidation of fear-like and anxiety-like behaviors. However, it is unclear whether the alterations in the NBM-BLA circuit promote negative affect during ethanol withdrawal (WD). Therefore, we performedex vivowhole-cell patch-clamp electrophysiology in both the NBM and the BLA of male Sprague Dawley rats following 10 d of chronic intermittent ethanol (CIE) exposure and 24 h of WD. We found that CIE exposure and withdrawal enhanced the neuronal excitability of NBM putative “cholinergic” neurons. We subsequently used optogenetics to directly manipulate NBM terminal activity within the BLA and measure cholinergic modulation of glutamatergic afferents and BLA pyramidal neurons. Our findings indicate that CIE and withdrawal upregulate NBM cholinergic facilitation of glutamate release via activation of presynaptic nicotinic acetylcholine receptors (AChRs). Ethanol withdrawal-induced increases in NBM terminal activity also enhance BLA pyramidal neuron firing. Collectively, our results provide a novel characterization of the NBM-BLA circuit and suggest that CIE-dependent modifications to NBM afferents enhance BLA pyramidal neuron activity during ethanol withdrawal.
Nociceptive Stimuli Activate the Hypothalamus–Habenula Circuit to Inhibit the Mesolimbic Reward System and Cocaine-Seeking Behaviors

Published: October 2022

Nociceptive signals interact with various regions of the brain, including those involved in physical sensation, reward, cognition, and emotion. Emerging evidence points to a role of nociception in the modulation of the mesolimbic reward system. The mechanism by which nociception affects dopamine (DA) signaling and reward is unclear. The lateral hypothalamus (LH) and the lateral habenula (LHb) receive somatosensory inputs and are structurally connected with the mesolimbic DA system. Here, we show that the LH–LHb pathway is necessary for nociceptive modulation of this system using male Sprague Dawley rats. Our extracellular single-unit recordings and head-mounted microendoscopic calcium imaging revealed that nociceptive stimulation by tail pinch excited LHb and LH neurons, which was inhibited by chemical lesion of the LH. Tail pinch increased activity of GABA neurons in ventral tegmental area, decreased the extracellular DA level in the nucleus accumbens ventrolateral shell in intact rats, and reduced cocaine-increased DA concentration, which was blocked by disruption of the LH. Furthermore, tail pinch attenuated cocaine-induced locomotor activity, 22 and 50 kHz ultrasonic vocalizations, and reinstatement of cocaine-seeking behavior, which was inhibited by chemogenetic silencing of the LH–LHb pathway. Our findings suggest that nociceptive stimulation recruits the LH–LHb pathway to inhibit mesolimbic DA system and drug reinstatement.SIGNIFICANCE STATEMENTThe LHb and the LH have been implicated in processing nociceptive signals and modulating DA release in the mesolimbic DA system. Here, we show that the LH–LHb pathway is critical for nociception-induced modulation of mesolimbic DA release and cocaine reinstatement. Nociceptive stimulation alleviates extracellular DA release in the mesolimbic DA system, cocaine-induced psychomotor activities, and reinstatement of cocaine-seeking behaviors through the LH–LHb pathway. These findings provide novel evidence for sensory modulation of the mesolimbic DA system and drug addiction.
