Published: October 2023

The present work is devoted to study and simulate of the functioning of monopolar HVDC LCC system of 500 kV in the presence of an AC power grids voltage disturbance. The CIGRE HVDC LCC Benchmark was simulated using MATLAB/Simulink in presence of AC grids voltage variations: first an overvoltage in AC grid 1 and second voltage drop in AC grid 2 have been simulated. All of these simulations are done to evaluate the robustness of the CIGRE HVDC LCC benchmark against AC grids voltage variation, and to investigate the ability of HVDC link function after disappearing of the simulated variation. The results showed that the HVDC LCC system is sensitive to overvoltage higher than 15 % appearing at the rectifier level, and is sensible too to voltage drops with more than 10 % at the invert level. In these conditions, a commutation failure leading to short-circuit was observed, which interrupt the HVDC link operation, and doesn’t permit re-establishment of link function after fault disappearing. To find the reason of the commutation failure appearing, the magnetic and electrostatic energies stored in DC filter elements have been measured and analyzed. The analysis show that when the magnetic energy is greater than the electrostatic one, the commutation failure appears.

Published: October 2023

In order to study the temperature change characteristics of Airbus 380 double-deck cabin in case of sudden fire, a three-dimensional cabin model is built at a 1:1 scale, and the fire temperature propagation process is simulated using Pyrosim software. It is found that the temperature at the front and rear seats of the cabin depends on the distance from the bulkhead at both ends, and the temperature at the middle position of the cabin mainly depends on the distance from the fire source. On the section of upper cabin z=4.1 m, the temperature change at the cabin tail starts first, and the temperature change at the cabin tail is local diffusion, while the temperature change at the cabin head is large diffusion at the beginning. The temperature changes at three altitudes in the upper cabin are generally the same at different times. The temperature at the stern of the cabin at z=3.1 m and z=3.5 m is higher than that at other positions, with the highest values of 296.5 K and 297.6 K respectively. The temperature at the head and stern of the cabin at z=4.1 m is higher than that at other positions.

Published: October 2023

The development of a new type of cold storage device must go through two stages: system design and performance verification. Therefore, what needs to be studied is to reduce the unit volume, reduce the rated power of the compressor and the cost of the refrigeration unit while meeting the cooling storage capacity, while also improving the refrigeration efficiency. In order to improve the cold storage capacity of small cold storage devices, aluminum was selected as the cold storage material in this study, and a spiral tube heat exchanger was used. The main research scenario is to simulate the temperature characteristics and analyze the results when the compressor stops working, and then establish an experimental platform to verify the results. Prove that the results of numerical simulation are reliable and reasonable, are in line with the actual situation, and meet the needs of production practice.

CAMP: A Unified Data Solution for Mandarin Speech Recognition Tasks
Authors: Min Zeping , Ge Qian , Li Zhong
Published: October 2023

Speech recognition, the transformation of spoken language into written text, is becoming increasingly vital across a broad range of applications. Despite the advancements in end-to-end Neural Network (NN) based speech recognition systems, the requirement for large volumes of annotated audio data tailored to specific scenarios remains a significant challenge. To address this, we introduce a novel approach, the Character Audio Mix-up (CAMP), which synthesizes scenario-specific audio data for Mandarin at a significantly reduced cost and effort. This method concatenates the audio segments of each character’s Pinyin in the text, obtained through force alignment on an existing annotated dataset, to synthesize the audio. These synthesized audios are then used to train the Automatic Speech Recognition (ASR) models. Experiments conducted on the AISHELL-3, and AIDATATANG datasets validate the effectiveness of CAMP, with ASR models trained on CAMP synthesized data performing relatively well compared to those trained with actual data from these datasets. Further, our ablation study reveals that while synthesized audio data can significantly reduce the need for real annotated audio specific to each scenario, it cannot entirely replace real audio. Thus, the importance of real annotated audio data in specific application scenarios is emphasized.

Published: October 2023

In today’s society, crown block is widely used in the construction industry, metallurgy industry and manufacturing industry. Its main task is to move goods to the target position quickly and accurately, and make the swing of goods as small as possible. How to reduce or restrain the swing of cargo load is a major problem faced by the research of crown block. In this paper, a control method based on linear quadratic optimal control algorithm (LQR) and particle swarm optimization algorithm (PSO) is proposed to reduce the swing of the crown block grab. The simplified mathematical model of the system based on the prototype is established through the derivation of Lagrange equation, and the stability of the system is judged by Lyapunov theory; PSO algorithm is used to search and optimize the output matrix parameters of LQR on the designed LQR controller for eliminating swing of crown block, and the final effect is verified through simulation. The final results show that the LQR controller optimized by PSO algorithm makes the swing time of the crown block grab significantly shorter, and the maximum overshoot of the grab swing reduces.
Use of an Electric-Reactive Engine in the Mode of Discrete Activations to Support the Working Orbit of a Small Spacecraft for Remote Earth Sensing
Authors: Volotsuev V.V. , Taneeva A.S.
Published: October 2023

The object of the research is a model of a small spacecraft for remote sensing of the Earth, located in a low near-circular orbit. An analysis is being made of the possibility of using an electric jet engine to maintain the radius of the working orbit of a spacecraft over a long time interval (5–7 years). It is assumed that the power plant of a small spacecraft is not capable of supporting the continuous operation of an electric jet engine throughout the entire orbit. The time of continuous operation is several minutes on orbit correction orbits. The range of change in the values of the ballistic coefficient of a small spacecraft depending on the orientation of the satellite during the flight is estimated. It is shown that the predicted time for reducing the average orbit height by 10–15% without correction does not exceed two years. With two or three switching on of the electric jet engine per day, it is possible to maintain the working orbit of the spacecraft in the condition of the Earth’s upper atmosphere, corresponding to low and medium levels of solar activity. With an increase in solar activity (respectively, the compaction of the Earth’s upper atmosphere at the studying height), a greater number of engine starts per day is required. The results obtained can be used in the design of motion control systems for a small Earth remote sensing spacecraft using an electric jet engine.

Published: October 2023

This study investigates the performance of a Fresnel lens solar concentrator system for solar concentration applications. A 300 mm x 300 mm polymethyl methacrylate Fresnel lens with concentric grooves of 0.24 mm height and 1.82 mm thickness was used. The lens’s geometrical profile was analyzed using a micrography observation approach to gain a better understanding of its geometry profile. Experiments were conducted with variations of operational parameters such as transversal and incidence angles. Trials were conducted at coordinates 6°02′04.8′′N 116°07′24.4′′E, between 1130 to 1330 hours, focusing on two major operational parameters (transversal and incidence angles). The receiver surface temperature was continuously recorded during the trials to determine solar concentrator heat energy gain. Both transversal and incidence angles had a significant impact on the system’s heat energy gain. The optimal configuration with lens transversal and incidence angles set to 90° and 5°, respectively, resulted in the highest heat gain of 8 kJ, achieving a concentration ratio of 16.42. These findings demonstrate the promising potential of Fresnel lens solar concentrators for practical solar concentration applications.

The stability of the slope body is controlled by more factors due to the large height of the slope. Therefore, the engineering reinforcement protection needs to take care of not only the overall and local stability of high slope, but also the stability of slope surface, slope and slope body, only in this way can the effective reinforcement protection of high slope be achieved. Since high slopes often have multi-layer outward potential slippery surface, it is generally advisable to implement the basic principle of “solid foot and strong waist” in the reinforcement and protection of high slopes from the aspects of engineering safety and economy, etc. In this paper, taking the excavation of the slopes on both sides of the shoulder of a reservoir as an example, the finite element strength reduction method is used to analyze the original slope collapse. The slope is mainly composed of fully and strongly weathered rocks, and the weakly weathered rocks are distributed in the lower part of the slope. According to the initial design plan, the deformation and instability of the excavated slope led to the sliding collapse of the front end of the slope. The slope ratio of the excavation at the foot of the slope was adjusted on the original basis, and anchor cables were used to reinforce the foot of the slope in layers, and the potential slippery surface of the slope may appear in multiple layers, and the potential slippery body of the high slope was divided into shallow, middle and deep potential slippery bodies for treatment. And in the project of layered support reinforcement, each layer coordinates with each other to ensure that the slopes of all levels in the high slope that may be controlled by potential slip in different depths are kept stable after reinforcement and treatment.

Optical properties of the luminaire efficiency were studied for different lighting glasses and lighting parameters of LED lamps (SB), (SBPT), (SBS), (SE) and (SEP) were calculated after test. Also, the magnitude of absorption, transmission and reflection were calculated for each lighting polymer glasses that fabricated, and the resultant lighting glass showed an excellent reflection property for UV visible test. The mechanical properties of impact strength were calculated and showed good resistivity to fracture better than raw materials. Based on the results and as a conclusion indicates that, if the corrugated edge of lighting polymer glass is directed into the luminaire body, then the efficiency is insignificant, but still increases and for the spectral transmittance depends not only on the composition of the lighting glass, but also on the geometry of the surface on which the light falls.
Variable selection in generalized extreme value regression model using Bootstrap method
Authors: Diop Aba , Niang Mouhamed Amine
Published: October 2023

In applied research in general, analysts frequently use variable selection methods in order to identify independent predictors of an outcome. The bootstrap method replaces complex analytical procedures by computer intensive empirical analysis. It relies heavily on Monte Carlo Method where several random resamples are drawn from a given original sample. The bootstrap method has been shown to be an effective technique in situations where it is necessary to determine the sampling distribution of (usually) a complex statistic with an unknown probability distribution using these data in a single sample. This work investigates the use of bootstrap tools in the context of variable selection in the generalized extreme value regression model. The treatment is based specifically upon drawing repeated bootstrap samples from the original dataset by founding the proportion of bootstrap samples in which each variable was identified as an independent predictor of the outcome. We performed a real data application and compared this approch with traditional model selection methods.

Published: October 2023

Alcohol consumption is associated with negative sexual outcomes among heavy drinking young adults. Smartphone interventions are a promising approach to reducing alcohol consumption. This study aimed to test whether a smartphone app designed to reduce heavy drinking (via feedback on the cued go/no-go task) would reduce reports of negative sexual outcomes, including unprotected sex and regretted sex. It was hypothesized that app use would be associated with fewer negative sexual outcomes, especially among women. Participants were young adult heavy drinkers (N = 49) aged 21 to 25 years old. Participants completed an in-person drinking session as well as a four-week field use period during which they used the app in drinking situations. Participants reported on their drinking consequences via the Young Adult Alcohol Consequences Questionnaire (YAACQ) at baseline, two- and four-week follow-ups, and six- and twelve-month follow-ups. No significant associations were found between app use and unprotected or regretted sex, but the results were in the predicted directions, especially among women. Given encouraging preliminary results, future studies with larger samples should test smartphone app interventions for young adult heavy drinking.
Multiscalar Assessment of Mining in River Floodplains of the Southeastern United States
Authors: Pietro Guarisco
Published: October 2023

The mining of sediment is a profitable activity involving clearing and digging out large tracts of land and transformation of the topography. Often, these mines, as well as the pits, ponds, and piles of sediment are near or within the floodplains of a fluvial system. During flood events, the river can overtop and erode riparian areas that separate it from the mine, flowing into the pit and causing planform changes including avulsions. The United States Geological Survey (USGS) has mapped mining sites across the United States, but there are still multiple omissions. Google Earth Pro was used to collect geospatial point data on mines that are within the floodplain boundaries of rivers and creeks in the southeast, a region of high biodiversity. Google Earth extracted data were compared to USGS data using ArcGIS Pro, and their proximity to floodplains and channels was analyzed. Distances between the channels and pits prior to avulsion were referenced from literature (Mossa & Marks, 2011) and used to assess potential risk for other sites. It was found that out of the 1,856 total pits from USGS and Google Earth data, 25.9% were omitted from the USGS data set. This supported the conclusion that current data sets, while thorough, are still incomplete and that a better understanding of site location can reduce the risk of avulsions, which can impact infrastructure, property boundaries, flood risk, and ecological health.
Monomania and Same-Sex Desires in Braddon's Lady Audley's Secret (1862)
Authors: Savannah Elaine Baggett
Published: October 2023

Mary Elizabeth Braddon’s Lady Audley’s Secret (1862) diagnoses Robert Audley as a monomaniac. With interest in psychiatry rising in nineteenth-century Britain, “monomania” was used to describe those who went against the norm. More specifically, it was used to describe those who had an obsessive interest in one subject. Robert’s monomaniacal nature arises from the homoerotic feelings he feels for his friend, George Talboys. After meeting George years later after their time at Eton College, a school that encouraged male love, Robert undergoes a journey to understand his homoerotic desire after George goes missing. By looking at the works of John Barlow, Jean-Étienne Dominique Esquirol, and James Cowles Prichard, I show how Braddon’s knowledge and usage of psychiatry can be seen and examined in her novel about marriage and desire In addition, I argue that Braddon demonstrates how Victorian ideas of masculinity and biblical manhood are intertwined within definitions of monomania and that these gendered concepts affect Robert as much as his psychological diagnosis.
Dissecting the Role of SAG101 in Extracellular NAD(P)+-Mediated Immune Signaling
Authors: Liu Emily , Zhou Mingxi , Mou Zhonglin
Published: October 2023

Plants are the primary source of food for all animals, but they are often infected by microbial pathogens, which reduces crop yield and threatens global food security. Therefore, plants have evolved sophisticated defense mechanisms to fend off microbial infections. EDS1, PAD4, and SAG101 are well-characterized plant immune regulators. While the EDS1-PAD4 complex was proven to be necessary for extracellular NAD(P) [eNAD(P)]-mediated immune signaling, the function of the EDS1-SAG101 complex in this pathway has yet to be determined. This research aimed to determine the necessity of SAG101 in the process of eNAD(P) signaling. Our hypothesis was that SAG101 formed a complex with EDS1 to carry out a necessary role in eNAD(P) signaling. Arabidopsis thaliana T-DNA insertion lines SALK_022911C and SALK_030411C were genotyped, and SALK_022911C was identified as a sag101 homozygous mutant. NAD(P)-induced immune responses in the sag101 mutant were compared to those in the eds1 and pad4 mutants. Exogenously applied NAD(P) induced expression of the defense marker genes, FMO1 and ALD1, as well as resistance to the bacterial pathogen Pseudomonas syringae pv. maculicola ES4326 in sag101. However, this induction was completely blocked in eds1 and pad4. These results demonstrate that the EDS1-SAG101 complex is not involved in the eNAD(P) signaling pathway and supports the model that the EDS1-PAD4 and EDS1-SAG101 complexes function differently in plant immunity.
The Role of Ciliary Melanin-Concentrating Hormone (MCH) Signaling in the Neurobehavioral Response to Cocaine
Authors: Shelowitz Amanda
Published: October 2023

Neuromodulatory peptides that modulate behavioral responses to psychostimulants are known to activate receptors enriched in neuronal primary cilia. Primary cilia are microtubule-based organelles that play a critical role in cellular signaling through their high density of G-protein-coupled receptors. One such receptor is the melanin-concentrating hormone receptor 1 (MCHR1). It is currently unclear how MCHR1 ciliary localization and MCH neuron activity modulate responses to psychostimulants. The objective of this project was to identify the role of primary cilia localized MCHR1 in modulating behavioral responses to cocaine. Male and female mice were subjected to conditioned place preference (CPP) to determine the rewarding effect of cocaine and locomotor activity tests. MCHR1 KO and MCHR1IFT88 KO strains exhibited increased acute locomotor responses and sensitization to cocaine compared to their control littermates. CPP testing showed that MCHR1 KO mice had a reduced preference to the cocaine-paired chamber compared to control littermates.  In contrast, MCHR1Ift88 KO mice did not differ from control littermates in the development of CPP.  Locomotor tests with MCHcre mice showed that activating MCH neurons 30min prior to cocaine administration resulted in decreased acute locomotor response and sensitization compared to mice that received saline and cocaine. These findings further support a role for MCH signaling in modulating response to psychostimulants and suggest that receptor loss and cilia loss impact responses differently.
The Biophysical and Emotional Effects of Dancing with a Partner
Authors: Lobosco Emily
Published: October 2023

The research on dance's emotional and biophysical effects on a person has expanded to include numerous studies. However, little evidence presents the correlation between dance partner-work – involving both  proximal and physical interaction – and the body's response. Recently, the limitations of engaging in partner-work due to COVID-19's social distancing measures created a heightened interest in this area of research. With this, an experimental study was conducted to explore potential correlations between partner dancing and the body. The main research question of this study asked how a dancer’s anxiety correlates with the degree of human connection throughout a choreographed duet. The methodology included recording biophysical data from two dancers as they performed a choreographed duet. Wearable technology measured each dancer's temperature, muscle contraction, heartbeat, electromyography, and spatial information. Brain function was also measured via a fourteen-channel EEG headset that allowed for whole-brain sensing. This data was recorded as the dancers moved together and independently from each other to compare the effects of varying degrees of contact on the body. To generate additional data, the anxiety levels of each subject were quantified through survey responses after they danced. Preliminary results support the assumption that proximal and physical interaction levels during dance directly impact a person's physical and emotional state. This study highlights the need and potential implications for additional research on brain-body responses to partner movement in dance.
Show Me Who You Respect and I Will Tell You What Your Culture Is
Authors: Dylan Gomez  , Klimenko Marina
Published: October 2023

Television shows can vary greatly between cultures, and it is possible that they may display what moral values are most important to a culture. In order to evaluate whether this is true the first author conducted a content analysis of the valence of moral values in French and Spanish television shows. This study analyzed the French show “Lupin” and the Spanish show “La Casa de Papel” which are both from the genre of crime and evaluated the valence of how the moral values of group loyalty and respect were depicted. Based on data from previous studies, the hypothesis was that the Spanish show would portray group loyalty as positive more often than the French show and would portray respect for authority negatively more often than the French show. The hypothesis was supported with regard to respect for authority, but not group loyalty which suggests that the hypothesis could be true but further research would be needed.
Nutrition Information on TikTok: A Qualitative Exploration of Posts from Registered Dietitian Nutritionists (RDN) and non-RDNs
Authors: Moore Madison
Published: October 2023

Registered Dietitian-Nutritionists (RDN) are using TikTok to promote their services and public nutrition knowledge. However, their viewer’s engagement and comments have yet to be explored. A descriptive qualitative study was conducted to identify the difference in posts by RDNs and non-RDNs. For one month, the engagement on posts from 4 creators (n=2 RDNs and n=2 non-RDNs) was recorded. The number of positive and negative comments and common comment topics were identified. Four post categories were identified: preparing meals, consuming nutritious food/meals, nutrition/diet tips, and indirectly nutrition related. Likes were the most common form of engagement. Most comments were positive (70%). The creators with more followers received more negative comments (27%) than those with less followers (6%). RDNs received more comments asking for nutrition advice (n>44) than non-RDNs (n<13). RDNs posted more about preparing meals and nutrition/diet tips while non-RDNs posted more about consuming nutritious food/meals and indirectly nutrition related. Informing RDNs of the usefulness of TikTok and of the expectations of their audience is important as the use of social media in health care is increasing. Thus, further research is important to ensure that we can inform RDNs on the best social media practices.

The type of ameloblastoma was varies, as the follicular type was found in 24 cases (57%), followed by the plexiform type which was found in 16 cases (38%) and the mixed plexiform-follicular type was found in 2 cases (5%). The treatment shows the conservative management of ameloblastoma using the dredging method in 9 patients (21%). Radical management of these data involved marginal resection in 1 patient (2%), segmental resection in 18 patients (43%), hemimaxillectomy in 3 patients (7%), and hemimandibulectomy in 11 patients (26%)
Conclusion: ameloblastoma is more common in women than men. The follicular type is more common than plexiform or the mixed type of ameloblastoma. Based on the location of the ameloblastoma, the most common is the mandible. Radical surgery is the most common used for ameloblastoma management.

A Rapid Post-earthquake Structural Damage Identification Method Based on Mode Shape Ratio Using Pattern Matching
Authors: Li Zuanfeng
Published: October 2023

This paper proposes a rapid identification method for post-earthquake structural damage based on mode shape ratio using pattern matching. In the first stage, the characteristic vector of mode shape ratio is calculated by modal analysis from the modal information of various damage scenarios to establish a pattern database. A small number of dynamic signals are collected for extracting the modal information to obtain the characteristic vector which is treated as the test pattern. Then the similarity between the test pattern and the pattern in the database is calculated using the Euclidean distance (ED). The damage location and severity of the measured structure are treated the same as the pattern corresponding to the minimum value of ED so that the damage is identified. Numerical simulations verify that the proposed method can well identify the damage. In addition, the matching results based on different sensor combinations demonstrate that the method can quickly identify the damage even using a limited number of sensors. The proposed method can provide support for the government to make a rapid post-earthquake emergency decision
Câncer e Gravidez: Sarcoma da Parede Abdominal com Várias Recidivas Ligadas a Gestações
Authors: Kroeff Mário
Published: October 2023

O caso descrito no presente trabalho mostra claramente a influência da gravidez na evolução do câncer. A manifestação inicial do sarcoma da parede abdominal surgiu com a primeira gestação da doente. Após o tratamento, houve várias recidivas (cinco) no prazo de alguns anos, todas consecutivas a outros tantos estados de gravidez. Esse e alguns casos mais, observados no Serviço Nacional de Câncer, deram-nos a impressão de que a gravidez tem Influência sobre o câncer e na maioria das vezes, agrava sua evolução.

"Radon": Considerações
Authors: Vieira Antonio Pinto
Published: October 2023

O autor, radioterapeuta do S.N.C., foi incumbido por seu Diretor, Dr. Mário Kroeff, de estudar o "radon'', importante agente radioterópico. Após ter conseguido bolsa de estudos por intermédio do "Institute of Interamerican Affairs'' permaneceu nos EE UU. da América durante um ano e dois mêses. Durante essa estada, frequentou o "Memorial Hospital" onde ao lado dos físicos L. Marinelli e G. Failla, familiarizou-se no manejo da aparelhagem, no modo de captação, acondicionamento e dosagem das células de "radon". Na Universidade de Colúmbia, seguiu o curso sôbre "física das irradiações" ministrado pela Dra. E. Quimby. Acompanhou durante três mêses o Serviço de Radioterapia do "Billings Hospital" e do "Hines Hospital'', respectivamente sob a orientação dos Drs. Anna Hamann e Harry Slobodin. Visitou em Chicago o "Tumor Institute'' do Dr. Max Cutler e a fábrica de aparêlhos de Raios X da General Electric. Em Nova lorque frequentou ainda, durante três mêses, o Serviço de Radioterapia do "Presbyterian Hospital'', chefiado pelo Dr. Maurice Lens.
Dois Casos de Mieloma Solitário
Authors: Kroeff Mário , Fialho Francisco
Published: October 2023

Os autores, após discutir o conceito atual do mieloma solitário, admitem sua existência. descrevem duas observações dêste tipo de tumor, que somadas às 63 outras citadas na literatura médica, elevam êste número a 65. Ambos os tumores eram constituídos por células semelhantes aos plasmócitos, recapitulando assim o tipo chamado plasmocitário. Em o primeiro dos casos é interessante referir o extenso comprometimento dos tecidos moles e as adenopatias metastáticas.
Câncer da Vesícula Biliar. Um Caso Tratado por Colecistectomia e Hepatectomia Parcial
Authors: Vianna João B.
Published: October 2023

Relato de caso de câncer de vesícula biliar com invasão parcial do fígado. A paciente de 68 anos apresentava fortes dores no quadrante superior direito do abdome. Um tumor duro foi palpado ali. O colecistograma foi negativo e o exame radiológico do estômago mostrou deformidade extrínseca do antro. Um diagnóstico provisório de câncer foi feito e confirmado por laparotomia. O fígado ao redor da vesícula biliar estava bastante invadido pelo tumor e parte do estômago estava muito aderida a ele. Colecistectomia com hepatectomia parcial e gastrectomia parcial atípica foram realizadas pelo autor. Uma sutura hemostática foi colocada no fígado antes de ser cortado pela faca elétrica. O abdome foi fechado sem drenagem. Uma fístula biliar se desenvolveu alguns dias depois, mas dentro de um mês. A vesícula biliar apresentava um grande cálculo solitário e o exame histológico mostrou que o tumor era um “carcinoma papilífero, originado na vesícula”. O autor não espera que um câncer de vesícula biliar tão avançado quanto o relatado possa ser curado, mas acredita que a colecistectomia com hepatectomia parcial trará algum alívio ao paciente e o transportará confortavelmente por algum tempo. Portanto, quando possível, a operação deve ser continuada, em vez de apenas remover um pedaço de tecido para biópsia e fechar o abdômen,
