Joint Embedding of Words and Labels for Sentiment Classification
Authors: Sheng Yingwei , Takashi Inui
Published: October 2021

With the fast growth of social networks, sentiment analysis on the web has been a popular research topic. Recently, word embedding-based sentiment analysis methods have reached outstanding performance compared to the traditional methods. However, word embeddings always ignore information from dataset’s labels. Inspired by the LEAM model proposed by Wang et al. [Joint embedding of words and labels for text classification (2018), arXiv:1805.04174], we propose a method that jointly learns information of words and sentiment labels, which can improve the performance of the label embedding model. We defined a set of sentiment lexicons and used it to represent sentiment labels in the proposed method. We finally conducted experiments on the Yelp dataset, which reached 65.03% accuracy when using the same setup as the baseline model, and 65.22% accuracy when using optional window sizes.
A Computational Study of the Reactions between Dehydrozingerone Derivatives and the Hydroperoxyl Radical in Aqueous and Lipid Media
Authors: Mansouri Hadjer , Mekelleche Sidi Mohamed
Published: October 2021

Dehydrozingerone (the half-analogue of curcumin) is a natural product that is isolated from ginger rhizomes. Recent studies have shown that this compound displays several physiological activities including antioxidant properties, and it can scavenge oxygen-free radicals like hydroxyl, peroxyl and superoxide radicals. In this work, the thermodynamic and kinetic aspects of the antiradical activity of the natural dehydrozingerone DHZ0 (R=H) and the designed derivatives DHZ1 (R=CHO), DHZ2 (R=OMe) and DHZ3 (R=NMe2) towards the hydroperoxyl radical (HOO•) were investigated at the M06-2X/6-311[Formula: see text]G([Formula: see text],[Formula: see text]) level of theory. The calculations have been performed in gas phase, pentyl ethanoate and water solvents using the implicit SMD solvation model. Four potential mechanisms have been investigated, namely, hydrogen atom transfer (HAT), single-electron transfer followed by proton transfer (SET-PT), sequential proton loss electron transfer (SPLET) and radical adduct formation (RAF). The obtained results show that the SET-PT and RAF mechanisms are endergonic processes and are thermodynamically disfavored, whereas the exergonic HAT process is predicted as the most thermodynamically favored mechanism in all media. The SPLET mechanism was excluded due the minor proportions of the anion species at physiological pH. Kinetic calculations show that DHZ3 reacts with HOO• 1860, 1250 and 215 times faster than DHZ0 in gas phase, pentyl ethanoate, and water, respectively. Based on thermodynamic and kinetic calculations, the designed compound DHZ3 is predicted as a good candidate for hydroperoxyl scavenging in both polar and nonpolar media. Drug likeness evaluation of the studied DHZ derivatives shows that the pharmacokinetic parameters satisfy all the Lipinski and Veber rules.
Strike-slip overprinting of initial co-axial shortening within the toe region of a submarine landslide and a model for basal shear surface growth: a case study from the Angoche Basin, offshore Mozambique
Authors: Abu Clara , Jackson Christopher A.-L. , Francis Malcolm
Published: October 2021

Submarine landslides (slides) are some of the most voluminous sediment gravity-flows on Earth and they dominate the stratigraphic record of many sedimentary basins. Their general kinematics and internal structure are relatively well-understood. However, how slides increase in volume and internally deform as they evolve, and how these processes relate, in time and space, to the growth of their basal (shear) zone, are poorly understood. We here use three high-resolution 3D seismic surveys from the Angoche Basin, offshore Mozambique to map strain within a shallowly buried, large, and thus seismically well-imaged slide (
c.
530 km
3
). We document several key kinematic indicators, including broadly NW-trending lateral margins and longitudinal shears bounding and within the slide body, respectively, and broadly NE-trending symmetric pop-up blocks in the slide toe. Approximately 7 km downdip of the slide toe wall, thrusts and related folds also occur within otherwise undeformed slope material, with thrusts detaching downwards onto the downslope continuation of the basal shear zone underlying the slide body. Based on the style, trend and distribution of these features, and their cross-cutting relationships, we propose an emplacement model involving two distinct phases of deformation: (i) bulk shortening, parallel to the overall SE-directed emplacement direction, with contractional shear strains reaching
c
. 8%; and (ii) the development of broadly emplacement direction-parallel shear zones that offset the earlier-formed shortening structures. We infer that the contractional strains basinward of the slide body formed due to cryptic basinward propagation of the basal shear zone
ahead
of, and to accommodate updip sliding and shortening associated with, the entire slide mass. Our study demonstrates the value of using 3D seismic reflection data to reveal slide emplacement kinematics, especially the multiphase, non-coaxial nature of deformation, and the dynamics of basal shear zone growth.
Design of the Poster Image System Based on Human Vision
Authors: Sun Xiaolifei
Published: October 2021

At present, the human visual perception system is the most effective, accurate, and fast image processing system in the world. This is because human eyes have some special visual features, but the features closely related to image enhancement include color constancy and brightness constancy. This paper presents a new image enhancement framework and computational model which can better simulate human visual features. It is based on the analysis of color constancy and luminance constancy and Retinex theory. And, this is a new image enhancement method in the compressed domain based on Retinex theory. In Retinex theory, DCT coefficients consist of incident components (DC coefficients) and reflection components (AC coefficients). By adjusting the dynamic range of DC coefficients, carefully adjusting AC coefficients, and using the threshold method for block suppression, the compressed domain image can be enhanced. On the basis of Retinex theory, the incident light and reflected light components are considered synthetically, the dynamic range (DC coefficient) of the incident light component and the details of the reflected light component (AC coefficient) are adjusted, and then the incident light component is reexamined. Moreover, it achieves a better image enhancement effect and avoids the blocking effect.

Published: October 2021

Deep neck infection is defined as an infectious process in the potential spaces and fascial plane of the neck which may result in a fatal complication. Prompt drainage and broad-spectrum antibiotics are the mainstays of treatment. Deep neck infection as the initial presentation of primary head and neck cancer is not common. Nevertheless, head and neck squamous cell carcinoma is the most common primary head and neck cancer, which could present with cervical metastasis and subsequently becomes infected. Papillary thyroid cancer has a naturally indolent course, and most patients present with a thyroid nodule. However, deep neck infection could be an uncommon presentation of papillary thyroid cancer which may obscure the diagnosis of underlying malignancy. This case report aims to present a rare presentation of papillary thyroid cancer which needs meticulous evaluation. Moreover, the pathological examination should be performed in all cases of deep neck infection for early detection and management of underlying papillary thyroid cancer.

Authors: Wang Yan , Wang Xiaoming , Liu Zhehan , Tang Wei , Li Jian , Nan De , Zou Shiya
Published: October 2021

Underwater nuclear explosions can be monitored in near real‐time by the hydroacoustic network of the International Monitoring System (IMS) established by the Comprehensive Nuclear‐Test‐Ban Treaty (CTBT), which could also be used to monitor underground and atmospheric nuclear explosions. The equivalent is an important parameter for the nuclear explosions’ monitoring. The traditional equivalent estimation method is to calculate the bubble pulsation period, which is difficult to obtain satisfactory results under the current conditions. In this paper, based on the passive sonar equation and the conversion process of acoustic energy parameters in the hydroacoustic station, the threshold monitoring technique used for underwater explosion equivalent estimation was studied, which was not limited to the measurement conditions and calculation results of the bubble pulsation period. Through the analysis of practical monitoring data, estimation on the underwater explosion equivalent based on the threshold monitoring technique was verified to be able to reach the accuracy upper boundary of current methods and expand the measurement range to further ocean space, along with the real‐time monitoring capability of IMS hydroacoustic stations which could be estimated by this method.

Digital Modeling of Heat Transfer during the Baking Process
Authors: Mosalam Heba
Published: October 2021

Numerical modeling and analysis of the baking process are challenging biochemical processes occurring in bread. These changes result from mass engineering tasks, usually characterized by the complex chain of chemical, physical, and heat transfer processes impacting the baking at the same time primarily caused by a variation of two dominating factors: (i) the heat and (ii) the internal moisture content at different temperatures and during the time’s process. This study presents an analysis of the 1-D computational fluid dynamics model for simultaneous heat transfer within a cylindrical bread sample. The numerical simulations were performed using the finite difference model (FDM) and the finite element model (FEM). In the first case, the proposed numerical model considered radiation and convection during sample heating and described the sample’s simultaneous heat, water, and vapor diffusion mechanisms. The calculations indicated that the FDM was susceptible to the time step; consequently, the range of 10 s and 100 s yielded the only relevant results. In the second case, the FEM was used to describe the phenomena of transportation during baking. Results obtained by the FEM showed a large temperature gradient near the surface. The study showed the presence of some critical cases that are considered the most influential on the stages of bread production. The first critical value is the time when the baking temperature reaches 100° C. The second critical value is the time when the liquid water content in the baking medium reaches its peak. The boundary conditions were examined and illustrated by figures in the center and the surface of the bread.

Published: October 2021

Background. Diabetic retinopathy (DR) is the most important manifestation of diabetic microangiopathy. It is essential to explore the gene regulatory relationship and genomic variation disturbance of biological networks in DR progression. Methods. In this study, we constructed a comprehensive lncRNA-mRNA ceRNA network of DR procession (CLMN) and explored its topological characteristics. Results. Modular and functional analysis indicated that the organization of CLMN performed fundamental and specific functions in diabetes and DR pathology. The differential expression of hub ceRNA nodes and positive correlation reveals the highly connected ceRNA regulation and important roles in the regulating of DR pathology. A large proportion of SNPs in the TFBS, DHS, and enhancer regions of lncRNAs will affect lncRNA transcription and further cause expression variation. Some SNPs were found to disrupt the lncRNA functional elements such as miRNA target binding sites. These results indicate the complex nature of genotypic effects in the disturbing of CLMN and further contribute to gene expression variation and different disease phenotypes. Conclusion. The identification of individual genomic variations and analysis of biological network disturbance by these genomic variations will help provide more personalized treatment plans and promote the development of precision medicine for DR.

This paper presents a cache performance model for embedded systems. The need for efficient cache design in embedded systems has led to the exploration of various methods of design for optimal cache configurations for embedded processor. Better users’ experiences are realized by improving performance parameters of embedded systems. This work presents a cache hit rate estimation model for embedded systems that can be used to explore optimal cache configurations using Bourneli’s binomial cumulative probability based on application of reuse distance profiles. The model presented was evaluated using three mibench benchmarks which are bitcount, basicmath and FFT for 4kb, 8kb, 16kb, 32kb and 64kb sizes of cache under 2-way, 4-ways, 8-ways and 16-ways set associative configurations, all using least recently-used (LRU) replacement policy. The results were compared with the results obtained using sim-cheetah from simplescalar simulators suite. The mean errors for bitcount, basicmath, and FFT benchmarks are 0.0263%, 2.4476%, and 1.9000% respectively. Therefore, the mean error for the three benchmarks is equal to 1.4579%. The margin of errors in the results was below 5% and within the acceptable limits showing that the model can be used to estimate hit rates of cache and to explore cache design options.

Published: October 2021

One of the methods used in detecting the intrusion detection system is by implementing Naïve Bayes algorithm. However, Naïve Bayes has a problem when one of the probabilities is 0, it will cause inaccurate prediction, or even no prediction was found. This paper proposed two modifications for Naïve Bayes algorithm. The first modification eliminated the variable that has 0 probability and the second modification changed the multiplication operations to addition operations. This modification is only applied when the Naïve Bayes algorithm does not find any prediction results caused by zero probabilities. The results of this research show that the value of precision, recall, and accuracy in the modification made tends to increase and better than the original Naïve Bayes algorithm. The highest precision, recall, and accuracy are obtained from modification by changing the multiplication operation to the addition. Increasing precision can reach 4%, increasing recall reaches 2% and increasing accuracy reaches 2%.
Optimal tuning of PI controllers using adaptive particle swarm optimization for doubly-fed induction generator connected to the grid during a voltage dip
Authors: Chetouani Elmostafa , Errami Youssef , Obbadi Abdellatif , Sahnoun Smail
Published: October 2021

This paper proposes the adaptive particle swarm optimization (APSO) technique to control the active and reactive power produced by a variable wind energy conversion system and the exchanged power between the electric grid and the system during a voltage dip (VD). Besides, to get the variable speed wind energy maximum power, a maximum power point (MPP) methodology is utilized. The system under study is a 5 MW wind turbine connected via a gearbox to a doubly-fed induction generator (DFIG). The DFIG stator is branched directly to the electrical network, while the Back-to-Back converters couple the rotor to the grid. The decoupled vector control of the rotor side converter and the grid side converter is established primarily by a conventional proportional-integral (PI) and a second level by an intelligent PI whose gains are tuned using the proposed control. The performances and results obtained by APSO tuned PI controllers are analyzed and compared with those attained by classical PI controllers through the MATLAB/Simulink. The superiority of the advised technique is examined during a two-phase short-circuit fault condition and confirmed by the reduced oscillations.

Published: October 2021

Chronic diseases quickly become broader public health issues because of the difficulty in obtaining appropriate, often long-term health care. So that, it requires the extension of health care for patients with chronic diseases beyond the clinic to include patient’s home and work environment. To reduce costs and provide more appropriate healthcare, we need telehealth care where internet of things (IoT) technology plays an important role. The integration of the IoT and medical science offers opportunities to improve healthcare quality, and efficiency and to better coordinate healthcare delivery at home and in the workplace. In this paper, we present the realization of a remote healthcare system based on the IoT technology. The function of this system is the transmission via a gateway of internet collected data using biomedical sensors node based Arduino board (e.g., temperature, electrical activity of the heart, heart rate monitor). These data will be stored automatically in a cloud. The health can then be monitored by the doctor or patient using a web page in real-time from anywhere at any time in the world using laptops or smart phones, etc. This method also reduces the need for direct interaction between doctor and patient.

Published: October 2021

There are certain challenges faced with wireless sensor networks (WSNs) performances, consumption can be seen amongst all these challenges as a serious area of research. Data from sensor nodes are transmitted by most WSN energy either among many nodes or to the base station (BS), and due this connection, several routing protocols were developed for supporting in data transmission in the WSNs. Extending network lifetime in an operational environment is the major objective of the wireless sensor network. Charging or exchanging sensor node batteries is almost impossible. Energy balancing and energy efficiency are significant research scopes as per designing of routing protocols aimed at self-organized WSNs. A heterogeneous WSN is one where every node has different amount of energy linked to it before it is deployed in a network. Therefore, different energy efficient routing protocols have been proposed which enables lesser consumption of energy, longer stability period which leads to the network lifetime increasing. In this study, the average energy of a WSN is computed after every logical round of operation for our protocol-HPEEA and compare it with two well-known heterogeneous protocols namely-SEP and CCS. At the end of the considered number of logical operations, MATLAB with simulation results confirm that HPEEA protocol have a reduction in the energy consumption compared to other protocols.

This paper presents a techno-economic analysis and environment assessment of hybrid photovoltaic (PV), wind turbine (WT), and diesel genset (DG) with pumped hydro storage (PHS) for a rural microgrid system. The analysis is carried out for a case study with Mentawai community load demand of 165.44 kWh/day at a peak load of 20.46 kW. The Homer simulation results show that there are eight feasible configurations, which the optimal hybrid system configuration to supply community load is the configuration with PV/DG/PHS. An optimal system has been achieved for the lowest NPC of Indonesian rupiah (IDR) 3,00 B consist of 15 kWp PV modules, 1 unit of PHS and a solar inverter with a size 25 kW. The net present cost and payback period are in accordance with criteria for the economic feasibility analysis method of a project. However, the cost of energy is greater than the electrical utility tariff, but this value can be considered for applications in the remote island area. Therefore, the project still feasible to be implemented. Since the renewable fraction of the system is increased hence this proposed system will have the lowest carbon emission.

In this paper, we propose a compact metamaterial structure loaded quad band antenna. The structural specifications/layout of the antenna consists of a circular ring monopole fed by a microstrip line. The ground part of the antenna is loaded with a metamaterial rectangular split-ring resonator (RSRR), an L-shaped slot, and two horizontally placed rectangular slots parallel to each other. No external matching circuit is utilized and impedance matching is solely controlled by the placement of slots. The antenna shows operation at 2.1 GHz (2.01-2.24 GHz, a bandwidth of 230 MHz (WLAN)), 4.5 GHz (4.35-4.66 GHz, a bandwidth of 310 MHz (C-band)), 5.5 GHz (5.37-5.77 GHz bandwidth of 400 MHz (WiMAX)), and 7.2 GHz (7.08-7.33 GHz, a bandwidth of 250 MHz (satellite band)). The antenna exhibits good gain and stable radiation pattern in both the plane and thus can be utilized for aforementioned applications.

Mysterious Bodies: Aristotelian Animal Generation and the Early Christian Doctrine of Bodily Resurrection
Authors: Peterson Anne Siebels , Peterson Brandon
Published: October 2021

In the fifteenth chapter of his first letter to the Corinthians, Paul makes a number of philosophically mysterious claims about the relationship between the ‘earthly’ body and the resurrected or ‘spiritual’ body. To what extent do these claims reflect themes present in Aristotle’s own views on the relationship between matter and organism? We will argue that Aristotle’s understanding of the relationship between matter and organism already reflects a commitment to the two central claims that Paul takes to be definitive of the relationship between earthly and spiritual body. On the one hand, Paul insists that the earthly body is not itself the resurrected or spiritual body, but only a seed that is sown for the latter. Further separating the earthly from the spiritual body, he compares their distinction to the distinction between the bodies of different animals. On the other hand, the chapter ends with language of continuity between the earthly and the spiritual body. Precisely this seeming conflict is present in Aristotle’s analysis of animal generation. Whereas many interpretations of Aristotle’s analysis privilege one side of the conflict over the other, I will argue that both must be equally privileged, yielding a parallel between the cases of animal generation in Aristotle and bodily resurrection in early Christianity.
The Use of Aristotle’s Biology in Nemesius’ On Human Nature
Authors: Tieleman Teun
Published: October 2021

Towards the end of the fourth century CE Nemesius, bishop of Emesa in Syria, composed his treatise On Human Nature (Περὶ φύσεως ἀνθρώπου). The nature of the soul and its relation to the body are central to Nemesius’ treatment. In developing his argument, he draws not only on Christian authors but on a variety of pagan philosophers such as Plato, Aristotle, the Stoics and the great physician-cum-philosopher Galen of Pergamum. This paper examines Nemesius’ references to Aristotle’s biology in particular, focusing on a few passages in the light of Aristotle’s Generation of Animals and History of Animals as well as the doxographic tradition. The themes in question are: the status of the intellect, the scale of nature and the respective roles of the male and female in reproduction. Central questions are: Exactly which impact did Aristotle make on his thinking? Was it mediated or direct? Why does Nemesius cite Aristotle and how? Long used as a source for earlier works now lost, Nemesius’ work may provide intriguing glimpses of the intellectual culture of his time. This paper is designed to contribute to this new approach to his work.
Education, Conflict and Harmony in Book 1 of Plato’s Laws
Authors: Rincón Diego García
Published: October 2021

Book 1 of Plato’s Laws, and particularly the image of the puppet introduced near its end, has been traditionally interpreted as presenting the moral psychology model that underlies the educational system delineated by the Athenian Stranger, which construes virtue as consonance between the non–rational and the rational elements of the soul. But a different and competing conception of virtue looms large in Laws 1, virtue as victory of the best part of the soul in psychic conflict. This paper argues that the Athenian’s conception of education as the correct conformation of originally conflicting psychic forces requires the simultaneous presence of the harmony and the conflict models of virtue in Laws 1. Education is in turn defined by calculation, the rational activity which persuasively leads the conflicting non–rational forces towards a consonant reciprocal rapport. By strategically developing his understanding of education and calculation in Laws 1, the Athenian shows how the harmony model of virtue overcomes the conflict model, while at the same time recognising that there is some truth to the conflict model after all and integrating it within the harmony model.

Published: October 2021

This paper aims at clarifying the procedure of proofs by reductio ad impossibile in Aristotle’s Prior Analytics, especially elucidating what can be taken as impossibility in such proofs. Traditional interpretation has it that the impossibility in Aristotle’s reductio proofs must be a contradiction. I argue for an alternative interpretation according to which both contrarieties and contradictions are suitable as the impossibility required by the proofs in question. I also present a definition of proof by reductio ad impossibile in accordance with the alternative interpretation.

Este estudo tem por objetivo investigar o uso da imagem feminina na gestão do turismo brasileiro a partir da construção ou manutenção de uma postura promovida pelos agente sociais dominantes (ASD) configurando um discurso do sujeito coletivo (DSC) que evidencia uma violência simbólica instaurada socialmente, bem como alguns de seus desdobramentos. A imagem de destino turístico oferece uma representação social de que no Brasil há o estímulo aos turistas estrangeiros para que venham usufruir sexualmente do corpo das mulheres brasileiras, causando grande indignação por parte dos cidadãos e cidadãs. Assim, o objetivo desta pesquisa é analisar como a produção discursiva relacionada à imagem de destinos turísticos que usa a imagem da mulher compõe um DSC e, por isso, precisa ser combatido. Foram consideradas opiniões e impressões a esse respeito coletadas em redes sociais. Como resultado deste trabalho, foi possível identificar conteúdos que suscitaram práticas discursivas bilaterais, seja para confrontar o DSC ou para reafirmá-lo.
Os impactos do coronavírus nos pequenos negócios de turismo no Brasil: uma análise a partir dos dados do Sebrae
Authors: Guerreiro Ana Clévia , Vilela Graziele
Published: October 2021

O turismo é um setor altamente vulnerável às crises externas e dependente de políticas públicas. Desde março de 2020, com a declaração pela Organização Mundial da Saúde do estado de pandemia do COVID-19, o setor enfrenta uma severa crise econômica. Apesar das ações de suporte que foram anunciadas pelos governos o cenário ainda é muito negativo. O Sebrae tem monitorado os impactos do Coronavírus nos pequenos negócios, que representam mais de 94% da cadeia produtiva do turismo no Brasil. A partir dos dados secundários oriundos da pesquisa on-line realizada pela instituição, o presente artigo apresenta, analisa e propõe uma reflexão crítica sobre os principais resultados registrados em doze variáveis. Nos sete meses avaliados, observou-se uma lenta recuperação dos pequenos negócios de turismo, notada pela alta quantidade de estabelecimentos ainda fechados, o que resultou em demissões; pela grande busca por empréstimos; e pelo alto número de empresas inadimplentes. Para reverter este quadro, para além das medidas genéricas em curso, são necessárias políticas públicas específicas para o setor.

We investigated behavioural patterns of school subjects from Colombia and Tenerife (Spain) of 10–12, 13–14 and 15–17 years old (150 per age group), during a crossed puzzle game. We video-recorded all sessions, elaborated an ethogram and classified behavioural patterns within functional categories (Empathy, Help Organizing, Agonistic, Cooperation, Selfishness and Tension-Distension); their frequencies were analyzed by Generalized Linear Mixed Models (GLMM). Results showed significant differences between countries in Help Organizing, Cooperation, Agonistic and Tension-Distension; the same categories except Cooperation differed between age ranges, but no category significantly differed between sexes. GLMM of factor scores from a principal component analysis applied to behavioural categories showed subjects from Colombian schools had significantly lower PC1 factor scores (Empathy, Selfishness and Tension-Distension) than those from Tenerife; the contrary occurred for PC2 (Help Organizing and Cooperation) and no significant difference was found for PC3 (Agonistic and Selfishness). We discuss several potential causes of the differences found.
Communication across multiple sensory modes: quantifying the rich behavioural repertoire of a Neotropical torrent frog
Authors: Augusto-Alves Guilherme , Toledo Luís Felipe

Anuran communication involves different channels of signal transmission, including acoustic, chemical, seismic, tactile, and visual stimuli. If emitted in combination, the components of the different channels form the multimodal communication, which can be important to reinforce, complement, or transfer fundamental information. This is especially key for species that dwell in noisy environments, such as Hylodes phyllodes. This rheophilic frog species has a complex behavioural repertoire, including acoustic and visual signals. In this study, we quantified and characterized the multimodal communication of this species. We identified and characterized advertisement, territorial, and encounter calls. Additionally, we compared the advertisement calls from the same males when emitted with one or both vocal sacs expanded and found that they differed in temporal and spectral parameters. Hylodes phyllodes performed 16 visual displays, which varied among individuals and populations. We elucidate that visual signalling is easily quantifiable and could be used to compare individuals, populations, and species, as typically done with anuran acoustic signals.
Love, Religion, and Secularity
Authors: Beit-Hallahmi Benjamin
Published: October 2021

McCaffree's challenge to traditional definitions of religion, and his suggestion that religiosity is about individual integration into a moral community are discussed. This is taken as an opportunity to examine difficulties in defining religion, and attempts to go around the definition issues by offering analogies. Religious emotion, as discussed by William James and Emile Durkheim, is found to be no different than strong emotions directed at our secular commitments. Devotion, and self-sacrifice are discussed in both religious and secular context. The denial of death and fantasies about an afterlife are central to religion, and are unlikely to disappear in the foreseeable future.
Experiences of the Non-religious in Psychotherapy

Published: October 2021

This study explores the experiences of non-religious clients in psychotherapy, specifically with regard to unwanted religious interventions. Because individuals who identify as non-religious often experience negative judgments of various kinds, they need a safe and accepting therapeutic environment. In the present study, clients expressed that 36 % of therapists reportedly engaged in either unwanted or unhelpful religious discussion, with 29 % explicitly suggesting a religious intervention for their non-religious clients, such as prayer or attendance at church services. For a small percentage of clients, these suggestions led to premature termination. Implications for professional practice, education, and public policy are suggested.
Statistical Assessment of Spatial Tornado Occurrences in Canada: Modeling and Estimation
Authors: Huang Q. , Jiang W. J. , Hong H. P.
Published: October 2021

Canada experiences a relatively large number of tornadoes, which can cause a significant amount of damage and fatalities. In this study, a preferred prediction model for the spatially varying tornado occurrence rate is developed for Canada. The development takes into account the most commonly used spatial stochastic models and the underreporting that is due to low population density. It incorporates the annual average cloud-to-ground lightning flash (ACGLF) density and annual average thunderstorm days (ATD) as covariates in the prediction model. The model parameters estimation is carried out by using both the maximum likelihood method and the Bayesian inference. The analysis results indicate that the negative binomial model is preferable to the zero-inflated Poisson model and the Poisson model. The results show that tornado occurrence in Canada is associated with large overdispersion. Also, the statistical analysis indicates that the prediction model for the tornado occurrence rate developed on the basis of Bayesian inference is relatively insensitive to the assumed “noninformative” prior distributions. A prediction model is suggested for the spatially varying tornado occurrence rate based on the negative binomial model with the ACGLF density and ATD as covariates.

Kidney biopsies are used sparingly to diagnose kidney injury in the clinic. Here we have conducted a small exploratory study to directly compare the low-grade kidney injury monitoring performance of serum safety biomarkers, novel urine safety biomarkers, microscopic histopathology and targeted gene expression alterations in kidney biopsy specimens in rhesus monkeys treated with tobramycin. Targeted gene expression increases were observed in the kidney biopsy samples and whole kidney sections for kidney injury molecule 1 ( KIM-1), clusterin ( CLU), osteopontin ( OPN) messenger RNA transcripts. In addition, increases of the urinary kidney safety protein biomarkers including KIM-1, CLU, OPN were also observed. These increases in gene expression and urinary protein end point were in concordance with the eventual low-grade kidney lesions seen in terminal tissue sections. In contrast, conventional serum biomarkers blood urea nitrogen and serum creatinine were not as sensitive in monitoring kidney injury. Although these data do not support routinely adding kidney biopsies to regular toxicology studies, they provide evidence on the value and limitations of incorporating gene expression profiling on kidney biopsy specimens, further underscore the value of urinary kidney safety biomarkers for improved low-grade kidney injury monitoring, and open the door for future definitive studies.
