Authors: Zhang Yakun , Zhao Lefa , Gao Ce
Published: December 2021

Herein, a well-designed nanohybrid Fe-MIL-88NH2 with regular octahedral structure was facilely fabricated by one-step hydrothermal strategy, which as a probe presents good fluorescent stability and sensitive discrimination for Glu in aqueous solution with a detection limit of 2.04 µM. Inspired by the predominant fluorescence property of Fe-MIL-88NH2, the biological application of the probe was conducted to evaluate the degrees of Glu in Hela cells with pleasing results. Furthermore, the visualized and user-friendly handy test strips for monitoring the levels of Glu in waste water have been designed, which exhibited a satisfactory visual phenomenon and could be visualized by naked eye.
Electrochemical Preparation of Highly Oriented Microporous Structure Nickel Oxide Films as Promising Electrodes in Urea Oxidation
Authors: Putri Yulia M T A , Gunlazuardi Jarnuzi , Ivandini Tribidasari A
Published: December 2021

Highly oriented microporous nickel oxide films were prepared through the simple and fast anodization of nickel foils at 30 V, followed by calcination at 400 °C. Low concentrations of ammonium chloride and potassium hydroxide solutions, which were dispersed in ethylene glycol, were used as electrolytes. Microporous dimensions and large surface areas of the films were obtained by using both electrolytes. The ammonium chloride system provided a highly oriented microporous structure with excellent distribution of pores at the surface of nickel foil. On the contrary, it was not uniform in the potassium hydroxide system. Furthermore, cyclic voltammetry of the microporous films in alkaline solutions containing urea showed the highest oxidation currents at the nickel oxide films prepared in the ammonium chloride system. This nickel oxide film also showed excellent stability of the current responses, indicating that the method has potential to be applied in electrode preparation, especially urea oxidation.
Measuring the Welfare Effects of Shame and Pride
Authors: Butera Luigi , Metcalfe Robert , Morrison William , Taubinsky Dmitry
Published: December 2021

Public recognition is frequently used to motivate desirable behavior, yet its welfare effects—such as costs of shame or gains from pride— are rarely measured. We develop a portable empirical methodology for measuring and monetizing social image utility, and we deploy it in experiments on exercise and charitable behavior. In all experiments, public recognition motivates desirable behavior but creates highly unequal image payoffs. High-performing individuals enjoy significant utility gains, while low-performing individuals incur significant utility losses. We estimate structural models of social signaling, and we use the models to explore the social efficiency of public recognition policies. (JEL C93, D64, D82, D91)
Intersemiotic translation from fairy tale to sculpture: An exploration of secondary narrativity
Authors: Li Wenjing , Zlatev Jordan
Published: December 2021

We present a cognitive semiotic case study of the narrative potential of the statue Den lille Havfrue (‘the little mermaid’) by Edvard Eriksen in Copenhagen. On the basis of theoretical analysis and a survey in which 20 European and 19 Chinese participants replied to questions concerning this statue we argue that it, and similar statues, may be considered as products of intersemiotic translation, but only if we dispense with any requirements of “equivalence” between source and target, since statues are necessarily semiotically highly reduced. While the source narratives constitute cases of primary narrativity, with narrations providing the audiences with stories, statues may partake only of secondary narrativity, where a prior story is needed for the statue to be understood as narration. In our study, this was reflected by correlations between reported prior knowledge and narrative (and possibly even non-narrative) interpretations of Den lille Havfrue. Finally, we relate the discussion to present-day cultural and political “settings”, where many statues, including Den lille Havfrue, have become part of a global anti-racism narrative.

Diffusion Approximations for a Class of Sequential Experimentation Problems
Authors: Araman Victor F. , Caldentey René A.
Published: December 2021

A decision maker (DM) must choose an action in order to maximize a reward function that depends on the DM’s action as well as on an unknown parameter Θ. The DM can delay taking the action in order to experiment and gather additional information on Θ. We model the problem using a Bayesian sequential experimentation framework and use dynamic programming and diffusion-asymptotic analysis to solve it. For that, we consider environments in which the average number of experiments that is conducted per unit of time is large and the informativeness of each individual experiment is low. Under such regimes, we derive a diffusion approximation for the sequential experimentation problem, which provides a number of important insights about the nature of the problem and its solution. First, it reveals that the problems of (i) selecting the optimal sequence of experiments to use and (ii) deciding the optimal time when to stop experimenting decouple and can be solved independently. Second, it shows that an optimal experimentation policy is one that chooses the experiment that maximizes the instantaneous volatility of the belief process. Third, the diffusion approximation provides a more mathematically malleable formulation that we can solve in closed form and suggests efficient heuristics for the nonasympototic regime. Our solution method also shows that the complexity of the problem grows only quadratically with the cardinality of the set of actions from which the decision maker can choose. We illustrate our methodology and results using a concrete application in the context of assortment selection and new product introduction. Specifically, we study the problem of a seller who wants to select an optimal assortment of products to launch into the marketplace and is uncertain about consumers’ preferences. Motivated by emerging practices in e-commerce, we assume that the seller is able to use a crowd voting system to learn these preferences before a final assortment decision is made. In this context, we undertake an extensive numerical analysis to assess the value of learning and demonstrate the effectiveness and robustness of the heuristics derived from the diffusion approximation.

Reading Between the Stars: Understanding the Effects of Online Customer Reviews on Product Demand
Authors: Cho Hallie S. , Sosa Manuel E. , Hasija Sameer
Published: December 2021

Problem definition: Many studies have examined quantitative customer reviews (i.e., star ratings) and found them to be a reliable source of information that has a positive effect on product demand. Yet the effect of qualitative customer reviews (i.e., text reviews) on demand has been less thoroughly studied, and it is not known whether (or how) the sentiment expressed in text reviews moderates the influence of star ratings on product demand. We are therefore led to examine how the interplay between review sentiment and star ratings affects product demand. Academic/practical relevance: Consumer perceptions of product quality and how they are shared via customer reviews are of extreme relevance to the firm, but we still do not understand how product demand is affected by the quantitative and qualitative aspects of customer reviews. Our paper seeks to fill this critical gap in the literature by analyzing star ratings, the sentiment of customer reviews, and their interaction. Methodology: Using 2002–2013 data for the U.S. automobile market, we investigate empirically the impact of star ratings and review sentiment on product demand. Thus, we estimate an aggregated multinomial choice model after performing a machine learning–based sentiment analysis on the entire corpus of customer reviews included in our sample. We take advantage of a quasi-exogenous shock to establish a causal link between online reviews and product demand. Results: We find robust empirical evidence that (i) review sentiment and star ratings both have a decreasingly positive effect on product demand and (ii) the effect (on demand) of their interaction suggests that the two components of reviews are complements. Positive sentiments in text reviews increase the positive effect of ratings when the effect of ratings is decidedly positive while they also compensate for the tendency of consumers to discount extremely high star ratings. Managerial implications: The firm should pay greater attention to quantitative and qualitative customer reviews to better understand how consumers perceive the quality of its offerings.

Um Storytelling da Pré-Escrita, Escrita e Pós-Escrita de um Caso para Ensino
Authors: Cruz Breno de Paula Andrade
Published: December 2021

O presente texto é um relato de experiência de um educador que usa da estratégia de storytelling para narrar seu processo de construção de um caso para ensino que é dividido em três etapas, são elas: (i) o processo de pré-escrita do caso – que tem como principal característica a definição aprofundada dos personagens e de possíveis conflitos, do contexto organizacional e das teorias utilizadas em um caso verossímel à realidade; (ii) o processo de escrita do caso – momento em que o autor evidencia os diálogos entre personagens e seus vínculos emocionais e afetivos, conecta o enredo com as teorias e apresenta elementos da realidade para aproximar o leitor daquele enredo e despertar seu interesse; e (iii) o processo de pós-escrita – momento em que se constroem as notas de ensino e se adequa o texto às exigências da literatura e do periódico a ser submetido o caso para ensino. Adicionalmente, conecta-se esse relato subjetivo do autor neste processo de sistematização da construção de casos para ensino aos resultados obtidos por ele como educador em disciplinas de graduação, com resultados dentro da sala de aula (interesse dos alunos na resolução dos casos) e fora da sala de aula (publicação dos casos em revistas e capítulos de livros com autoria dos alunos a partir dos seus trabalhos finais na disciplina).
Aplicação de Casos para Ensino em Cursos de Administração: A Inovatividade do Professor influencia nos Resultados de Aprendizagem?
Authors: Morais Dafne , Souza Elnivan
Published: December 2021

A aplicação de casos para ensino desponta como um método promissor, capaz de encurtar distâncias entre a sala de aula e a realidade organizacional. No contexto brasileiro, a utilização do método do caso ainda é recente e enfrenta barreiras que impedem sua disseminação. A despeito do crescimento do número de casos de ensino publicados nacionalmente, ainda existe uma lacuna entre a publicação e a aplicação, de fato, do caso em sala de aula. Entre recomendações para aprofundar o conhecimento sobre a aplicação de casos para ensino, está o chamado por realizar pesquisas que articulem a voz de dois atores: o professor e o gestor das Instituições de Ensino Superior. Nesse sentido, o presente estudo investiga a perspectiva do docente sobre a aplicação de casos para ensino, e questiona: Qual a impacto da Inovatividade Individual do professor nos Resultados de Aprendizagem, considerando o contexto de aplicação de casos para ensino em Administração? Para isso, utilizaram-se um levantamento junto a 100 professores de diversas regiões do país. Os dados foram tratados por meio de modelagem de equações estruturais e os resultados indicam que, na perspectiva do professor, a inovatividade individual deste, no contexto de aplicação de casos para ensino, influencia positivamente os resultados de aprendizagem dos alunos.
Dual stereo-digital image correlation system for simultaneous measurement of overlapped wings with a polarization RGB camera and fluorescent speckle patterns
Authors: Chen Zhenning , Xu Yinuo , Tang Xinqiao , Shao Xinxing , Sun Wei , He Xiaoyuan
Published: December 2021

Simultaneous monitoring of overlapped multi-wing structure by stereo-digital image correlation (stereo-DIC) may be used to quantify insect motion and deformation. We propose a dual stereo-DIC system based on multispectral imaging with a polarization RGB camera. Different fluorescent speckle patterns were fabricated on wings, which emit red and blue spectra under ultraviolet light that were imaged and separated using a polarization RGB camera and auxiliary optical splitting components. The resulting dual stereo-DIC system was validated through translation experiments with transparent sheets and reconstructed overlapped insect wings (cicadas). Dynamic measurements of the Ruban artificial flier indicate the efficacy of this approach to determining real insect flight behavior.
Lateral shifts of linearly- and radially-polarized Bessel beams scattered by a nanosphere

Published: December 2021

We report the investigation on the lateral shifts that linearly-polarized (LP) and radially-polarized (RP) Bessel beams experience during the Mie scattering by a nanosphere. A numerical procedure based on the angular spectrum theory is developed to solve the scattered electromagnetic field and subsequent lateral shifts with a high computational efficiency, which can be easily applied to an arbitrary shaped polarized beam. The influences of different factors, including conical angle, nanosphere radius and position, on the lateral shifts are systematically investigated. The results demonstrate that for on-axis scattering, a LP Bessel beam can be regarded as a plane wave with the same polarization state but an equivalent longer wavelength, while a RP Bessel beam can be regarded as a plane wave with a polarization state along the propagation direction exhibiting independence on the conical angle. The findings help deepen our understandings of lateral shifts in light scattering of vectorial non-diffractive beams.
Residue calibrated least-squares unwrapping algorithm for noisy and steep phase maps
Authors: Wei Cong , Ma Jun , Miao Xinyu , Wang Nianfeng , Zong Yi , Yuan Caojin
Published: December 2021

This work proposes a robust unwrapping algorithm for noisy and steep phase maps based on the residue calibrated least-squares method. The proposed algorithm calculates and calibrates the residues in the derivative maps to get a noise-free Poisson equation. Moreover, it compensates for the residuals between the wrapped and unwrapped phase maps iteratively to eliminate approximation errors and the smoothing effect of the least-squares method. The robustness and efficiency of the proposed algorithm are validated by unwrapping simulated and experimentally wrapped phase maps. Compared with the other three typical algorithms, the proposed algorithm has the most effective performance in noisy and steep phase unwrapping, providing a reliable alternative for practical applications.
Nonlinear light amplification via 3D plasmonic nanocavities
Authors: Shen Shaoxin , Zeng Yue , Zheng Zehuan , Gao Renxian , Sun Guoya , Yang Zhilin
Published: December 2021

Plasmonic nanocavities offer prospects for the amplification of inherently weak nonlinear responses at subwavelength scales. However, constructing these nanocavities with tunable modal volumes and reduced optical losses remains an open challenge in the development of nonlinear nanophotonics. Herein, we design and fabricate three-dimensional (3D) metal-dielectric-metal (MDM) plasmonic nanocavities that are capable of amplifying second-harmonic lights by up to three orders of magnitude with respect to dielectric-metal counterparts. In combination with experimental estimations of quantitative contributions of constituent parts in proposed 3D MDM designs, we further theoretically disclose the mechanism governing this signal amplification. We discover that this phenomenon can be attributed to the plasmon hybridization of both dipolar plasmon resonances and gap cavity resonances, such that an energy exchange channel can be attained and helps expand modal volumes while maintaining strong field localizations. Our results may advance the understanding of efficient nonlinear harmonic generations in 3D plasmonic nanostructures.
Influence of the a-directed off-cut on the opto-electrical properties of laser diodes grown on the 0.3° misoriented m-directed GaN substrate

Published: December 2021

We report on the results of the investigation of the influence of an additional a-directed off-cut of the substrate on the opto-electrical properties of the laser diodes grown on bulk GaN with initial misorientation 0.3° towards the m-direction. The investigated a-directed off-cut is varied from 0° up to 1° by means of multilevel laser lithography and dry etching. The results show that the increase of the a-directed off-cut causes the decrease of internal optical losses and increase of injection efficiency. In consequence, the devices fabricated on the wafer areas characterized by higher a-directed off cut are characterized by the lower threshold current, and higher slope and wall-plug efficiencies.

Authors: Ikeda Kenji , Kobayashi Nobukiyo , Arai Ken-Ichi
Published: December 2021

Nanogranular films consisting of a complex of nanometer-sized magnetic granules and a dielectric insulator matrix exhibit a large Faraday rotation. In this study, the dielectric tensor of the nanogranular films with high refractive silicon nitride matrix are measured, and the effect of refractive index of the matrix and magnetic granules on the dielectric tensor is analyzed. Compared with the fluoride (low refractive index) matrix nanogranular films, the Faraday rotation angle is approximately two times higher in the nanogranular FeCo-SiN film, which exhibits a high refractive index effect on the Faraday rotation angle.

Respiratory syncytial virus (RSV) infection results in millions of hospitalizations and thousands of deaths each year. Variations in the adaptive and innate immune response appear to be associated with RSV severity. To investigate the host response to RSV infection in infants, we performed a systems-level study of RSV pathophysiology, incorporating high-throughput measurements of the peripheral innate and adaptive immune systems and the airway epithelium and microbiota. We implemented a novel multi-omic data integration method based on multilayered principal component analysis, penalized regression, and feature weight back-propagation, which enabled us to identify cellular pathways associated with RSV severity. In both airway and immune cells, we found an association between RSV severity and activation of pathways controlling Th17 and acute phase response signaling, as well as inhibition of B cell receptor signaling. Dysregulation of both the humoral and mucosal response to RSV may play a critical role in determining illness severity.
Measuring context dependency in birdsong using artificial neural networks
Authors: Morita Takashi , Koda Hiroki , Okanoya Kazuo , Tachibana Ryosuke O.
Published: December 2021

Context dependency is a key feature in sequential structures of human language, which requires reference between words far apart in the produced sequence. Assessing how long the past context has an effect on the current status provides crucial information to understand the mechanism for complex sequential behaviors. Birdsongs serve as a representative model for studying the context dependency in sequential signals produced by non-human animals, while previous reports were upper-bounded by methodological limitations. Here, we newly estimated the context dependency in birdsongs in a more scalable way using a modern neural-network-based language model whose accessible context length is sufficiently long. The detected context dependency was beyond the order of traditional Markovian models of birdsong, but was consistent with previous experimental investigations. We also studied the relation between the assumed/auto-detected vocabulary size of birdsong (i.e., fine- vs. coarse-grained syllable classifications) and the context dependency. It turned out that the larger vocabulary (or the more fine-grained classification) is assumed, the shorter context dependency is detected.
Modelling interference between vectors of non-persistently transmitted plant viruses to identify effective control strategies
Authors: Zaffaroni Marta , Rimbaud Loup , Mailleret Ludovic , Cunniffe Nik J. , Bevacqua Daniele
Published: December 2021

Aphids are the primary vector of plant viruses. Transient aphids, which probe several plants per day, are considered to be the principal vectors of non-persistently transmitted (NPT) viruses. However, resident aphids, which can complete their life cycle on a single host and are affected by agronomic practices, can transmit NPT viruses as well. Moreover, they can interfere both directly and indirectly with transient aphids, eventually shaping plant disease dynamics. By means of an epidemiological model, originally accounting for ecological principles and agronomic practices, we explore the consequences of fertilization and irrigation, pesticide deployment and roguing of infected plants on the spread of viral diseases in crops. Our results indicate that the spread of NPT viruses can be i) both reduced or increased by fertilization and irrigation, depending on whether the interference is direct or indirect; ii) counter-intuitively increased by pesticide application and iii) reduced by roguing infected plants. We show that a better understanding of vectors’ interactions would enhance our understanding of disease transmission, supporting the development of disease management strategies.
Improving sexually transmitted infection screening, testing, and treatment among people with HIV: A mixed method needs assessment to inform a multi-site, multi-level intervention and evaluation plan

Published: December 2021

Bacterial sexually transmitted infections (STIs) continue to be a worsening public health concern in the United States (US). Though the national incidence of HIV infection has decreased over recent years, that of chlamydia, gonorrhea, and syphilis have not. Despite national recommendations on prevention, screening, and treatment of these STIs, these practices have not been standardized. Nine Health Resources and Services Administration Ryan White HIV/AIDS Program funded clinics across 3 US jurisdictions (Florida, Louisiana, and Washington, DC), were selected as clinical demonstration sites to be evaluated in this mixed method needs assessment to inform a multi-site, multi-level intervention to evaluate evidence-based interventions to improve STI screening and testing of bacterial STIs among people with or at risk for HIV. These 3 US jurisdictions were selected due to having higher than national average incidence rates of HIV and bacterial STIs. Descriptive statistics and deductive analysis were used to assess quantitative and qualitative needs assessment data. Results indicate the following needs across participating sites: inconsistent and irregular comprehensive sexual behavior history taking within and among sites, limited routine bacterial STI testing (once/year and if symptomatic) not in accordance with CDC recommendations, limited extragenital site gonorrhea/chlamydia testing, limited annual training on STI-related topics including LGBTQ health and adolescent/young adult sexual health, and limited efforts for making high-STI incidence individuals feel welcome in the clinic (primarily LGBTQ individuals and adolescents/young adults). These findings were used to identify interventions to be used to increase routine screenings and testing for bacterial STIs.
Neisseria gonorrhoeae subverts formin-dependent actin polymerization to colonize human macrophages
Authors: Ivanov Stanimir S. , Castore Reneau , Juarez Rodriguez Maria Dolores , Circu Magdalena , Dragoi Ana-Maria
Published: December 2021

Dynamic reorganization of the actin cytoskeleton dictates plasma membrane morphogenesis and is frequently subverted by bacterial pathogens for entry and colonization of host cells. The human-adapted bacterial pathogen Neisseria gonorrhoeae can colonize and replicate when cultured with human macrophages, however the basic understanding of how this process occurs is incomplete. N. gonorrhoeae is the etiological agent of the sexually transmitted disease gonorrhea and tissue resident macrophages are present in the urogenital mucosa, which is colonized by the bacteria. We uncovered that when gonococci colonize macrophages, they can establish an intracellular or a cell surface-associated niche that support bacterial replication independently. Unlike other intracellular bacterial pathogens, which enter host cells as single bacterium, establish an intracellular niche and then replicate, gonococci invade human macrophages as a colony. Individual diplococci are rapidly phagocytosed by macrophages and transported to lysosomes for degradation. However, we found that surface-associated gonococcal colonies of various sizes can invade macrophages by triggering actin skeleton rearrangement resulting in plasma membrane invaginations that slowly engulf the colony. The resulting intracellular membrane-bound organelle supports robust bacterial replication. The gonococci-occupied vacuoles evaded fusion with the endosomal compartment and were enveloped by a network of actin filaments. We demonstrate that gonococcal colonies invade macrophages via a process mechanistically distinct from phagocytosis that is regulated by the actin nucleating factor FMNL3 and is independent of the Arp2/3 complex. Our work provides insights into the gonococci life-cycle in association with human macrophages and defines key host determinants for macrophage colonization.
Cruising the staged Wonderland: Scenographic photography and the queering of space
Authors: Coyle Sean
Published: December 2021

This article attempts to introduce and define the creative practice of ‘scenographic photography’ through the exploration of a body of practice-based research completed as part of a Ph.D. at the University of Tasmania in 2018. As research, it examines how traditionally representational forms of photography and scenography can inform each other through the more performative mode of ‘scenographic photography’, an interdisciplinary neologism operating between the performing, spatial and visual arts. Throughout this article, in attempting to define ‘scenographic photography’ as an emergent field, I will concurrently explore how queer space making was used as a critical tool for the research, visualization, execution and exhibiting of this body of work. The title of the body of work – Cruising Wonderland – refers to a specific ‘beat’ site in Sydney associated with illicit encounters and the homophobic violence it engendered during the 1980s, as well as an embodied means of re-presenting such traumatic histories. Within Cruising Wonderland scenographic scale-model making is adopted as a critical tool with which to interrogate specific sites of queer trauma. The inherent ‘wonder’ and fascination associated with the art of the miniature encourages the possibility of a reparative reading not always possible via the explicit documentary tradition of photographing actual sites of trauma. Once presented the audience are required to ‘cruise’ the darkened exhibition environment, like the ‘beat’ spaces referenced in the work, with an acute sensory awareness of their surroundings, of fellow spectators and how they, as participants within Wonderland, perform and are perceived by others. This immersive approach to engaging with the work is designed to encourage a process of empathic engagement, illuminating often-invisible histories, allowing us to move towards reparation through active re-witnessing.
Fitting materials: Costume flows, intra-actions and agency in and around the fitting room
Authors: Taylor Madeline
Published: December 2021

The costume fitting room has long been considered an essential space in developing a character, with many actors crediting the fitting as a critical stage in creating or understanding their character. In these spaces, characters and costume designs emerge and evolve. This article argues that active in this emergence are actors, designers and costumers and the costume itself. This research explores the costume’s agentic nature in the performance-making process, using ethnographic observation of Australian theatre costume fitting rooms. It evidences the multiple, disparate and sometimes surprising elements that impact character portrayal and design development. The agency of the costume as a creative partner is currently a topic of debate in costume research. Leaning into this conversation, this article draws on Karan Barad’s perspectives of new materialism to argue for greater consideration of the costume’s influence and value in forming a performance work. Recognizing this contribution and the affective power of costume prompts a challenge to the structures and practices surrounding actors and costumes and how they intra-act. The article concludes by reflecting on the implications for current industry rehearsal, production and costume practices.

Authors: Kuroda Y.
Published: December 2021

The aim of this study was to determine the factors associated with dysphagia in the hospitalized older adults. The dysphagia group consisted of 46 patients (23 men and 23 women) while the non-dysphagia group consisted of 40 patients (10 men and 30 women). The measurements included Mini Nutritional Assessment Short-Form (MNA-SF) scores, serum albumin levels, anthropometrics, and a mobility index. The dysphagia group was older and had significantly higher rates of male sex, respiratory disease on admission, dementia, other neurological disease, and impaired mobility than the non-dysphagia group. The dysphagia group also showed significantly lower values in nutritional measurements including MNA-SF scores, serum albumin levels. Logistic regression analysis showed that the factors significantly and independently associated with dysphagia were impaired mobility, dementia, and male gender. The results of present study showed that hospitalized

Published: December 2021

Introduction: The present study is justified by the interest of investigating the impact of nutritional status on urology patients. Objective: To investigate the nutritional status of urology patients and identify the risk factors associated with type of kidney stone. Method: This cross-sectional study assessed the nutritional status and energy and nutrient intakes of 175 hospitalized adult urology patients stratified as follows: patients submitted to percutaneous nephrolithotripsy (PN), patients submitted to endoscopic ureterolithotripsy (EU), and patients without kidney stones. All study variables were investigated as possible predictors of urologic diseases. Multinomial logistic regression analysis and the proportional odds model identified the factors associated with kidney stones. The significance level was set at 5%. Results: Kidney stones were more common in females (p<0.0001), EU patients without nutritional risk according to the Nutritional Risk Screening (NRS) (p=0.0061), patients with normal triceps skinfold thickness (p=0.015), and younger patients (p=0.0001). Patients hospitalized for longer periods (p=0.0038) and older patients (p=0.0001) did not have kidney stones. In EU patients kidney stones were associated with being female (p<0.0001; OR: 3.699; CI: 2.001; 6.838), having mid-upper arm muscle circumference between the 10th and 90th percentiles (p=0.0477; OR: 3.164; CI: 1.012; 9.895), not being at nutritional risk according to the NRS (p=0.0308; OR: 3.265; IC: 1.116; 9.557), and being younger (p=0.0008; OR: 0.966; CI: 2.001; 6.838). Conclusion: PN patients seem to need nutritional assessment and follow-up, while patients with kidney stones smaller than one centimeter do not seem to need routine nutritional assessment.

Published: December 2021

An esophagopleural fistula (EPF) is a rare condition. EPFs are typically of spontaneous, iatrogenic, or neoplastic origin. A 50-year-old man with hepatitis C and alcoholic cirrhosis presented with a history of recurrent variceal hemorrhage requiring esophageal banding, Minnesota tube placement, and a transjugular intrahepatic portosystemic shunt. His hospital course after esophageal perforation and EPF was complicated by acute respiratory failure and empyema, necessitating intubation and thoracostomy tube placement. To the best of our knowledge, this is the first reported case of EPF secondary to Minnesota tube placement. The EPF completely healed after endoscopic repair.

For patients after bariatric surgery, diagnosis of gastric cancer is a challenge. We present a patient after Roux-en-Y gastric bypass with upper abdominal pain and abnormal computed tomography scan with diffuse wall thickening of the gastric antrum. Various biopsy techniques have been described, with surgical (laparoscopic) exploration being the most common. We were able to successfully diagnose gastric cancer in the excluded stomach by biopsy using a jejunogastrostomy, which proved to be safe and effective.

Authors: Zyablikov V. M. , Goncharov S. Yu.
Published: December 2021

Methods are presented that simplify the calculation of the main sizes of couplings with packages of flat springs for power drives of machines. The main parameter of such couplings is torsional stiffness, which must be provided during their design. Given a number of parameters, first of all, the size of the cross sections of elastic elements, their number in the package, the number of packages is graphically determined, the diameter of the circle on which they are located, the length of flat springs. At the same time, their bending strength is guaranteed. The graphical solution of the task allows you to purposefully adjust, if necessary, the design parameters and dimensions of the couplings.

BACKLASH-FREE POWER DRIVE OF MACHINES
Authors: Zyablikov V. M.
Published: December 2021

Thebacklash-freepower drive of the machines ensures that the working shaft does not move freely when changing the direction of rotation. As a backlash-freegapless power drive, a single-stage planetary gearbox is proposed, containing two Central wheels, a carrier, and satellites, which are blocks of two gears, each of which is mounted on the carrierʼs axis by means of a rolling bearing and a freerunning Cam clutch. At the same time, the couplings are placed so as to ensure free rotation of the wheels in different directions. The gears are connected to each other by a pre-twisted cylindrical torsion spring. The proposed design will ensure reliable operation of the drive when the specified requirements are met.

Published: December 2021

At present time, in control systems, an electromechanical drive, which includes a reduction gear, is widely used. To ensure the quality of the output movement of the drive, it is not enough synthesize it according to the criteria of performance and accuracy. With increasing requirements for drives, the need arose for such an indicator of the quality of dynamics as smoothness [1], which is mainly influenced by the quality of the mechanical transmission production. The article provides an example of modeling a reduction gear taking into account multi-massage, the number of teeth, geometric errors of tooth-engagement, imbalance of the engine rotor. The spectrum of speed fluctuations of the output link is obtained, which characterizes the smoothness of the reduction gear operation. A conclusion is made about the prospect of using a model approach to diagnose the smooth operation of reduction gears.
