Application of elastically protected hydraulic vibration damper in spring suspension of locomotives
Authors: Savos'kin A. N. , Lavlinskaya N. S. , Ivanov P. Yu.
Published: June 2022

Introduction. In the undercarriage of modern locomotives hydraulic vibration dampers are widely used to dampen vertical vibrations that occur in the axlebox stage of the spring suspension. Their resistance force is directly proportional to the deformation rate of the spring set. High levels of vibration frequencies and amplitudes in the axlebox stage lead to a significant increase in the strain rate and dissipative forces, which causes frequent failures of hydraulic vibration dampers. Therefore, issues related to improving the performance of axlebox hydraulic dampers are actual.

Materials and methods. In order to evaluate the effectiveness of elastically protected hydraulic vibration damper in axlebox suspension, the authors studied the vibrations of a simplified model of a 2ES5K electric locomotive with a typical layout of the axlebox stage of spring suspension and a circuit with an elastically protected hydraulic vibration damper. The authors used a high-frequency random process as a kinematic perturbation of vibrations. The system of differential equations was solved in the MatLab — Simulink software package by numerical integration using the Runge — Kutta method of the fourth order. As a result of the solution, realisation of stationary and ergodic random processes were obtained.

 Results. The comparison of the obtained characteristics of random processes of vibrations of these two options showed that the use of an elastically protected axlebox vibration damper significantly reduces the frequency range and amplitudes of dissipative forces, which ensures a reduction in the number of axlebox damper failures and an increase in the number of runs before replacement is required.

Discussion and conclusion. The shown efficiency of using an elastically protected axlebox vibration damper allows increasing the reliability of the damper. In order to determine the distance run between overhauls, it is necessary to carry out a controlled operation cycle or test the prototype axlebox assembly with the elastically protected vibration damper and measure the parameters of such assembly.

Introduction.Traffic and transportation capacities of railway polygons and traffic flows are not constant throughout the year. Permissible capacity levels are determined by the condition of unhindered reception of trains by stations. It is necessary to calculate the balance of transportation capacity, making it possible to combine growing traffic with high rates with infrastructure development and repair works. The purpose of the study is to develop methodological solutions for assessing the balance of the railway transportation capacity and substantiating the procedure for implementing infrastructure measures in the context of the growing dynamics of the originating traffic and the tight deadlines for repairing and reconstructing the infrastructure.

Materials and methods.The developed solutions are based on the data of the Russian Railways information systems, automated forecasting of the infrastructure and transportation resources of the railway network, and hybrid mathematical models.

Results.The article presented the results of the substantiation of the normative restrictions on the daily time budget for the passage of trains, depending on the classification and specialisation of railway lines. The procedure for calculating the traffic capacity of sections with automatic locomotive signalling is determined as an independent means of interval control of train traffic with movable boundaries of block sections that change depending on the speed and mass of the train. The characteristics of the available, estimated, planned and required traffic and transportation capacities were determined with a distinction between measures for the development of traffic and transportation capacities and programs for improvement of infrastructure facilities. The authors put forward the problem of compromise management to ensure the required volumes of freight and passenger traffic, a given volume of reconstruction work on the development of infrastructure and repair work to maintain the required degree of its readiness. A classification of reconstructive, technological, organisational, technical and complex measures of influence on the unevenness of transport processes in the conditions of depletion of infrastructure and scheduling resources was presented.

Discussion and conclusion.The developed solutions enable to increase the feasibility and efficiency of complex projects for the development of traffic and transportation capacities and measures to improve the operation of railway network polygons.

Introduction. Each scientific journal should meet the needs of its readers and the imperatives of its time. The journal can acquire such status if it accomplishes its main mission: increasing the volume of scientific knowledge available to the society. This requires organisation of a meaningful scientific discourse on its pages. The purpose of the article is to study the history of the Railways Technology Journal development after the Victory in the Great Patriotic War, when the post-war restoration of the economy and the intensive development of communications using advanced scientific knowledge became the topmost priorities. The article ends with an assessment of the current state of the journal and future prospects for its development.

Materials and methods. The authors used historical, analytical and logical methods of scientific knowledge.

Results. The Railways Technology Journal archives testified to the serious changes that took place in scientific journalism. The editorial staff was constantly looking for new ways of interacting with readers, optimising the format of the journal, redefining sections, etc. Ultimately, the journal was renamed: since 1956 the Railways Technology Journal became known as the Bulletin of the All-Union Railway Research Institute. To a large extent, this was due to fundamental changes in the activities of the publisher, the Central Research Institute of the People's Commissariat of Communication Routes of the USSR.

 Discussion and conclusion. The study of the history of the country's leading railway science journal enables to draw conclusions about the state of the science at the time, as well as the goals set by the country and about the era as a whole.

The publication is the final part of the article dedicated to the 80th Anniversary of the journal. Part 1. See the war years in Vol. 80, no. 6.

Heart Rate Variability Biofeedback to Treat Anxiety in Young People With Autism Spectrum Disorder: Findings From a Home-Based Pilot Study
Authors: Coulter Helen , Donnelly Mark , Mallett John , Kernohan W George
Published: June 2022

Background

People with autism spectrum disorder (ASD) frequently experience high levels of anxiety. Despite this, many clinical settings do not provide specialist ASD mental health services, and demand for professional support frequently outstrips supply. Across many sectors of health, investigators have explored digital health solutions to mitigate demand and extend the reach of professional practice beyond traditional clinical settings.

Objective

This critical appraisal and pilot feasibility study examines heart rate variability (HRV) biofeedback as an approach to help young people with ASD to manage anxiety symptoms outside of formal settings. The aim is to explore the use of portable biofeedback devices to manage anxiety, while also highlighting the risks and benefits of this approach with this population.

Methods

We assessed the feasibility of using home-based HRV biofeedback for self-management of anxiety in young people with ASD. We adopted coproduction, involving people with ASD, to facilitate development of the study design. Next, a separate pilot with 20 participants with ASD (n=16, 80% male participants and n=4, 20% female participants, aged 13-24 years; IQ>70) assessed adoption and acceptability of HRV biofeedback devices for home use over a 12-week period. Data were collected from both carers and participants through questionnaires and interviews; participants also provided single-lead electrocardiogram recordings as well as daily reports through smartphone on adoption and use of their device.

Results

Pre-post participant questionnaires indicated a significant reduction in anxiety in children (t6=2.55; P=.04; Cohen d=0.99) as well as adults (t7=3.95; P=.006; Cohen d=0.54). Participant age was significantly negatively correlated with all HRV variables at baseline, namely high-frequency heart rate variability (HF-HRV: P=.02), the root mean square of successive differences in normal heartbeat contractions (RMSSD: P=.02) and the variability of normal-to-normal interbeat intervals (SDNN: P=.04). At follow-up, only SDNN was significantly negatively correlated with age (P=.05). Levels of ASD symptoms were positively correlated with heart rate both before (P=.04) and after the intervention (P=.01). The majority (311/474, 65.6%) of reports from participants indicated that the devices helped when used. Difficulties with the use of some devices and problems with home testing of HRV were noted. These initial findings are discussed within the context of the strengths and challenges of remotely delivering a biofeedback intervention for people with ASD.

Conclusions

HRV biofeedback devices have shown promise in this pilot study. There is now a need for larger evaluation of biofeedback to determine which delivery methods achieve the greatest effect for people with ASD.

The Association Between the Use of Low-Slice Computed Tomography Machines and Downstream Care: Comparative Study of 16-Slice and 64-Slice Computed Tomography Angiography (Preprint)
Authors: Powell Adam C , Long James W , Deshmukh Uday U , Simmons Jeffrey D
Published: June 2022

BACKGROUND

Although computed tomography (CT) studies on machines with more slices have reported higher positive and negative predictive values, the impact of using low-slice (16-slice) CT machines on downstream testing has not been well studied. In community outpatient settings, low-slice CT machines remain in use, although many hospitals have adopted higher-slice machines.

OBJECTIVE

This study examines the association between the use of low-slice CT machines and downstream invasive testing in the context of the CT angiography of the neck.

METHODS

Included health insurance claims pertained to adults with commercial or Medicare Advantage health plans who underwent the CT angiography of the neck. Site certification data were used to assign counts of slices to claims. Claims that were made in the 60 days after CT were examined for cervicocerebral angiography. The association between the number of slices and cervicocerebral angiography was evaluated by using a chi-square test and multivariate logistic regression.

RESULTS

Claims for 16-slice CT had a 5.1% (33/641) downstream cervicocerebral angiography rate, while claims for 64-slice CT had a 3.1% (35/1125) rate, and a significant difference (P=.03) was observed. An analysis that was adjusted for patient demographics also found a significant relationship (odds ratio 1.64, 95% CI 1.00-2.69; P=.047).

CONCLUSIONS

The use of low-slice CT machines in the community may impact the quality of care and result in more downstream testing.
Health Consumer Engagement, Enablement, and Empowerment in Smartphone-Enabled Home-Based Diagnostic Testing for Viral Infections: Mixed Methods Study (Preprint)
Authors: LeRouge Cynthia , Durneva Polina , Lyon Victoria , Thompson Matthew
Published: June 2022

BACKGROUND

Health consumers are increasingly taking a more substantial role in decision-making and self-care regarding their health. A range of digital technologies is available for laypeople to find, share, and generate health-related information that supports their health care processes. There is also innovation and interest in home testing enabled by smartphone technology (smartphone-supported home testing [smart HT]). However, few studies have focused on the process from initial engagement to acting on the test results, which involves multiple decisions.

OBJECTIVE

This study aimed to identify and model the key factors leading to health consumers’ engagement and enablement associated with smart HT. We also explored multiple levels of health care choices resulting from health consumer empowerment and activation from smart HT use. Understanding the factors and choices associated with engagement, enablement, empowerment, and activation helps both research and practice to support the intended and optimal use of smart HT.

METHODS

This study reports the findings from 2 phases of a more extensive pilot study of smart HT for viral infection. In these 2 phases, we used mixed methods (semistructured interviews and surveys) to shed light on the situated complexities of health consumers making autonomous decisions to engage with, perform, and act on smart HT, supporting the diagnostic aspects of their health care. Interview (n=31) and survey (n=282) participants underwent smart HT testing for influenza in earlier pilot phases. The survey also extended the viral infection context to include questions related to potential smart HT use for SARS-CoV-2 diagnosis.

RESULTS

Our resulting model revealed the smart HT engagement and enablement factors, as well as choices resulting from empowerment and activation. The model included factors leading to engagement, specifically various intrinsic and extrinsic influences. Moreover, the model included various enablement factors, including the quality of smart HT and the personal capacity to perform smart HT. The model also explores various choices resulting from empowerment and activation from the perspectives of various stakeholders (public vs private) and concerning different levels of impact (personal vs distant).

CONCLUSIONS

The findings provide insight into the nuanced and complex ways health consumers make decisions to engage with and perform smart HT and how they may react to positive results in terms of public-private and personal-distant dimensions. Moreover, the study illuminates the role that providers and smart HT sources can play to better support digitally engaged health consumers in the smart HT decision process.
A Randomized Factorial Trial of Internet-Delivered Cognitive Behaviour Therapy for Post-Secondary Students: Examining Motivational Interviewing and Booster Lessons (Preprint)
Authors: Peynenburg Vanessa , Hadjistavropoulos Heather , Thiessen David , Titov Nick , Dear Blake
Published: June 2022

BACKGROUND

Internet-delivered cognitive behaviour therapy (ICBT) can improve access to mental healthcare for students, although high attrition rates are concerning, and little is known about long-term outcomes. Motivational interviewing (MI) exercises and booster lessons can improve engagement and outcomes in face-to-face CBT.

OBJECTIVE

The current study was designed to examine the use of pre-treatment MI exercises and booster lessons in ICBT for post-secondary students.

METHODS

In this factorial trial (factor 1: online MI pre-treatment; factor 2: self-guided booster lesson 1-month post-treatment), 308 clients were randomized to one of four treatment conditions, with 277 (89.9%) clients starting treatment. All clients received a 5-week transdiagnostic ICBT course (the UniWellbeing Course). Primary outcomes included changes in depression, anxiety, and perceived academic functioning from pre-treatment to post-treatment and 1- and 3-month follow-up.

RESULTS

Overall, 54.0% (n=150) of students completed treatment and reported large improvements in symptoms of depression and anxiety, and small improvements in academic functioning at post-treatment, which were maintained at 1- and 3-month follow-up. Pre-treatment MI did not contribute to better treatment completion or engagement, but small between-group effects favoured MI for reductions in depression (Cohen’s d: 0.23) and anxiety (Cohen’s d: 0.25) at post-treatment. Only 30.9% (n=43) of students randomized to one of the booster conditions accessed the booster. No main effects were found for booster overall. Sub-analyses revealed that clients who accessed the booster had larger decreases in depressive symptoms (Cohen’s d: 0.31) at 3-month follow-up. No interactions were found between MI and booster.

CONCLUSIONS

Rather than offering MI at pre-treatment, clients may experience more benefit from MI exercises later in ICBT when motivation wanes. Low uptake of the self-guided booster limits our conclusions about its effectiveness. Future research should examine offering a booster at a longer duration after treatment, with therapist support, and with a longer follow-up period.

Geographical Indication (GI) defined as a designation used for products that strongly attached with their origins. The purposes of the study are: to find out consumer behavior at all buying decision stages, to see their perception of agro-geographical indication products, and to determine the most considered attributes in buying decision process of the products. Questionnaires had been distributed to 240 respondents using a purposive sampling technique to collect relevant data for achieving the research’s purposes. Population proportion and Fishbein multi-attributes model were used to analyze the obtained data. Buying decision process of agrogeographical indication products was differentiated into five stages, namely: need recognition; information gathering; alternatives evaluation; purchase decision; and post-purchase behavior. We found the importanceof product’s authenticity at the first stage of buying decision process; the internet and social media as the primary source for GI’s product information at the second stage; and product indigenousness at the third stage. At the fourth stage, most consumers bought the product in the traditional market; and the fifth stage, we found that most of them satisfied with the products, its price, and considered to purchase more in the future. Most of the consumer has a good perception of GI products. However; they had not prioritized GI products over other similar products. The quality of the GI products was the most considered factor in buying decision.

Se aplicó una encuesta de 32 ítems a 584 hoteles de 3 o más estrellas de los Estados Unidos y México. Se utilizó la técnica estadística de ecuaciones estructurales por mínimos cuadrados parciales.  Resultados: se evidencia la existencia de una relación directa entrela mayoría de los factores analizados entre ellos mismos y el incrementodel desempeño de los hoteles. Existe una fuerte conexión entre la gestión de la calidad total y la responsabilidad social corporativa. Empero, la orientación emprendedora sólo influye sobre la calidad total y no sobre la responsabilidad social como relación directa ni tampoco como efecto moderador. Finalmente, existe efecto mediador de la calidad total en relación con la orientación emprendedora y el desempeño. Limitaciones de la investigación: la principal limitación fue el acceso para encuestar a los hoteles debido a la pandemia por COVID-19. Hallazgos: los factores inciden en un mejor desempeño, sin embargo, la adopción simultánea de todos no permite maximizar los beneficios. Consecuentemente, termina generando fuerte gasto de tiempo y recursos en relación con el aumento adicional del desempeño.

Abstract: The days have come when people are increasingly using apps on their smart devices. Every day everyone generates millions of data per second. As for usage increases, so soon negative actions such as rumors and false stories on social media also increase. To resolve this issue, we have proposed a "Fake News Detection using Feature Selection and Deep Learning" feature. To develop an automated rumor detection model, this study prefers a hybrid model to separate rumors using an Deep Learning (Convolution Neural Network) and a filter-wrapper (Artificial Bee Colony) classified by the Naïve Bayes classifier as a test algorithm. The feature set uses a mixed model with CNN as an Deep learning model and ABC as a training data filter model and the results are applied to the Naïve Bayes classifier to calculate accuracy.

Abstract: The shampoo sector is probably the largest unit sale among the hair care products since shampoos are one of the cosmetic products used in daily life. Synthetic preservatives and detergents have sometimes been the cause of adverse effects among consumers. A more radical approach in reducing the synthetic ingredients is by incorporating natural extract whose functionality is comparable with their synthetic ingredients. A shampoo is a cleaning aid for the hair and is counted among the foremost beauty products. Today’s shampoo formulations are beyond the stage of pure cleaning of the hair. Additional benefits are expected, e.g., conditioning, smoothing of the hair surface, good health of hair, i.e., hair free of dandruff, dirt, grease and lice and, above all, its safety benefits are expected. As the scalp is one of the most absorbent part of the body, products applied to the scalp go directly to the blood, without being filtered in any way. In the scenario of changing food habits, stress level and dependent environment conditions, number of skin and hair disorders are encountered. This herbal shampoo was formulated using natural ingredient like Fenugreek seeds), Acacia concinna (shikakai), Sapindus mukorossi (reetha), Ocimum sanctum (tulsi), Aloe vera (aloe), Hibiscus rosa sinensis (china rose), Embelica officinalis (amla), Lawsonia inermis (henna),Citrus lemon (lemon), with proven efficacy of hair care preparation is prepared. The combination of several such ingredient of herbal origin has made it possible to secure highly effective dry powder shampoo. The formulation at laboratory scale was done and evaluated for number of parameters to ensure its safety and efficacy

Authors: Oubrahim Imadeddine , Sefiani Naoufal , Happonen Ari
Published: June 2022

Our structured literature review reveals the current state-of-the-art supply chain performance evaluation models (SCPEMs) from the last 21 years of research. Seventy related papers from the 2000 to 2021 time period were found to contribute by using ISI and SCOPUS databases. This paper has classified SCPEMs in terms of focus area and the perspective considered (financial and non-financial). With the analysis, these models’ applicability in today’s business environment pinpointed the most usable models and their current shortcomings. Findings disclose current SCPEMs limitations and misalignments with the emerging disruptive technologies observed in today’s supply chains. Given the findings, this study has highlighted the lack of overall supply chain performance evaluation and the failure to underline the underperforming decision criteria in the SC network. Therefore, to tackle these gaps, the authors have suggested visibility, leagility, collaboration, digitalization, sustainability, and integration as SCM characteristics to be considered in the future when developing a novel SCPEM. Finally, this study can be used as guidance for future studies.

At present, public transport needs to be managed using the different models, which will take into account health problems, passenger transport problems, refinement of technical parameters of buses and their adaptation to urban operating conditions, which would be one of the preventive measures in the context of combating the coronavirus pandemic. The article discusses the issues of optimizing the routeing scheme of buses and minibuses in the conditions of a three-level transport network in large cities. Measures for the performance of the city bus routes have been developed. It has been established that the qualification of a driver and the selection of urban passenger vehicles are central issues in terms of fuel efficiency and reducing the number of harmful substances in exhaust gases.

Published: June 2022

A high efficiency of sowing grain crops by ears was noted in breeding and primary seed production. It was found that a seeder with working bodies for sowing by ears helps to significantly (up to 8 times) reduce labor intensity as well as maintain the variety purity in comparison with the use of manual labor.

Research purpose To develop a seeder working section with a tape-cassette sowing device for sowing grain crops by ears in breeding and seed nurseries, and to substantiate the sowing device parameters necessary for the design of a multi-section grain seeder.

Materials and methods In the course of the experiments, the authors proposed a schematic diagram, a program and a method for testing a cassette seeder working section for sowing by ears.  A sample of the seed section was examined in the laboratory. The ways of ensuring the variety purity in conditions of grain natural shedding were studied. A technology of sowing ears in capsules was used.

Results and discussion It was proposed to equip the seeder cassette sowing device with a device for pushing the capsule with the ear out of the cassette tape cell. A mock-up model of a spiked seed drill section was developed. The operation of the tape-cassette sowing device was checked.

Conclusions The advisable parameters of the cassette tape cells specified are as follows: the inner diameter is 2.3-2.5 centimeters, the length is 14.0-16.5 centimeters, the distance between the axes is 3-4 centimeters. A formula for calculating the number of cells in a cassette tape was obtained depending on the number of tape turns in the cassette. The initial requirements and terms of reference were developed for the experimental sample of the grain drill section. The data were summarized to design a multi-section seeder for sowing with ears.
A game of quantum advantage: linking verification and simulation
Authors: Stilck França Daniel , Garcia-Patron Raul
Published: June 2022

We present a formalism that captures the process of proving quantum superiority to skeptics as an interactive game between two agents, supervised by a referee. Bob, is sampling from a classical distribution on a quantum device that is supposed to demonstrate a quantum advantage. The other player, the skeptical Alice, is then allowed to propose mock distributions supposed to reproduce Bob's device's statistics. He then needs to provide witness functions to prove that Alice's proposed mock distributions cannot properly approximate his device. Within this framework, we establish three results. First, for random quantum circuits, Bob being able to efficiently distinguish his distribution from Alice's implies efficient approximate simulation of the distribution. Secondly, finding a polynomial time function to distinguish the output of random circuits from the uniform distribution can also spoof the heavy output generation problem in polynomial time. This pinpoints that exponential resources may be unavoidable for even the most basic verification tasks in the setting of random quantum circuits. Beyond this setting, by employing strong data processing inequalities, our framework allows us to analyse the effect of noise on classical simulability and verification of more general near-term quantum advantage proposals.

Authors: Ruiz Pérez Jose Ignacio , Herrera Rojas Aura Nidia
Published: June 2022

Se analizó el papel del género con relación a dos estrategias de evaluación de intereses sexuales: una versión reducida ad-hoc del Inventario Multifásico de la Sexualidad (IMS) y una tarea de medición de Tiempos de Reacción a Estímulos Sexuales visuales (TRES). Con una muestra incidental de 60 sujetos se analizaron las propiedades psicométricas de una versión de 56 ítems del IMS. La prueba TRES se basó en imágenes de contenidos heterosexuales, homosexuales, de adultos, infantiles y neutrales presentadas en computador. Los resultados muestran una fiabilidad interna aceptable de varias de las subescalas del IMS, y validez de constructo entre ellas. En el IMS, los hombres mostraron más distorsiones cognitivas y obsesiones sexuales, inicio más temprano en la sexualidad y menor deseabilidad social en temas sexuales. En relación con la prueba TRES, las mujeres emplearon menos tiempo ante imágenes de adultos (d de Cohen: 0,85), y más ante imágenes de niños y neutrales (d: 0.61 y d: 0.75). Se encontraron varias correlaciones significativas entre subescalas del IMS y las dimensiones TRES.

Debido a la gran cantidad de datos generados por la sociedad, conceptos como Big Data, Minería de datos, Analítica de datos y Open Data se abren paso como herramientas que permiten su tratamiento, consulta y análisis, y que aplicando algoritmos de Inteligencia Artificial ayudan a encontrar y comprender patrones de comportamiento gracias a la Datificación. El objetivo de la investigación es identificar casos de aplicaciones del uso de la Datificación y las herramientas de análisis de datos, en América Latina entre el 2015 y 2019, y reseñar cómo estas tecnologías afectan las dinámicas en diversos escenarios sociales de la región. La investigación se realizó utilizando una metodología descriptiva. La población objetivo está representada principalmente por países de América Latina, aunque se incluyen algunos casos de Estados Unidos y España. El estudio se dividió en cuatro fases. Se evidencia que la Datificación y las tecnologías asociadas, están transformando la sociedad en los países objeto de estudio, reflejándose mejoras en la calidad de vida de sus ciudadanos, principalmente en sectores como Gestión Pública y Seguridad. Se resalta que hay carencia de leyes que regulen cuestiones de protección y tratamiento de datos privados, especialmente en el campo tecnológico, lo cual se traduce en un reto de seguridad de información que debe ser atendido de forma interdisciplinar.
