An Improved Z-Source Inverter Topology with Fewer Passive Components: Hardware Validation and Modelling
Authors: Tyagi Tushar , Singh Amit Kumar , Sharma Himanshu , Khanna Rintu
Published: August 2024

This research investigated a novel Z-source inverter architecture with fewer passive components. The offered inverter has several advantages, including low-frequency switching at 50 Hz, a straightforward modulation technique, and a constant input current. Low switching frequency results in fewer switching losses, which improves the overall efficiency of the inverter. The adoption of a straightforward modulation method allows for more exact control of the output voltage frequency. Because of these qualities, this inverter architecture can be employed in solar applications. This provides a thorough examination of shoot-through and non-shoot-through modes. The comprehensive mathematical underpinning of various modes is described here, and the established mathematical equations are shown to be consistent with the simulation. The number of components, which is only four in number, switching frequency, and boost factor of the presented topology prototype are compared to various well-known topologies in the literature. The power density of the inverter is 25% higher than the topology having the fewest number of components as reported till date for a single phase Z-source inverter. Finally, a laboratory prototype is created to corroborate the analysis and validation of the data reported by the MATLAB simulation.
Research progress on NLRP3 inflammasomes in male reproductive immunity

Published: August 2024

The male reproductive immune system plays a pivotal role in safeguarding sperm from immune attacks and preventing the incursion of foreign pathogens. Nucleotide-binding and oligomerization domain-like receptors (NOD-like receptors, NLRs) family protein domain containing 3 (NLRP3) is a cytoplasmic sensor binding to the inflammasome and critically involved in inducing innate immunity in the testes. It also has a substantial impact on male reproductive immunity, which is closely associated with male infertility stemming from disorders related to the male reproductive immune system. This review introduces the distinct characteristics of the NLR family, elucidates the activation pathways and factors of NLRP3 inflammasomes, and discusses how they participate in male reproductive immune diseases such as bacterial orchitis, autoimmune orchitis, varicocele, and epididymitis. In bacterial orchitis, elevated levels of NLRP3 inflammasomes exacerbate the testicular inflammatory injury and lead to decreased testosterone, thus contributing to male infertility. In autoimmune orchitis, the NLRP3 inflammasomes inhibit testosterone synthesis by decreasing the expression of cytochrome P450, thereby impacting male reproductive function. Therefore, targeting NLRP3 could offer novel immunological strategies for the clinical treatment of male infertility.

National Trends in External-Beam Radiation Therapy for Brain Metastases from Lung, Breast, and Melanoma Cancers
Authors: Rajkumar Sujay , Desai Jay , Shepard Matthew J. , Wegner Rodney E.
Published: August 2024

Objective:

Radiation therapy (RT) in the form of stereotactic radiosurgery (SRS) or whole-brain radiation therapy (WBRT) is fundamental for managing brain metastasis (BM). We analyzed national trends in RT and BM patient survival between 2010 and 2019.

Materials and Methods:

The US National Cancer Database was queried for patients receiving RT for BMs who were originally diagnosed with primary non-small cell lung cancer (NSCLC), small cell lung cancer, breast cancer, and melanomas from 2010 to 2019. Patients were grouped by WBRT (5-15 fractions; 20-45 Gy) or SRS (1-5 fractions; 10-40 Gy) treatment. Univariate and multivariate logistic regression analyses identified factors associated with receiving SRS over WBRT. Differences in treatment trends were assessed with Kruskal-Wallis tests. Post-treatment survival was assessed using Kaplan-Meier analysis and a Cox proportional hazards model.

Results:

In total, 59,839 patients were included; 41,197 (68.8%) received WBRT and 18,642 (31.2%) received SRS. Patients who were more recently diagnosed, treated at facilities outside of the East Central regions, insured, diagnosed with NSCLC subtype or melanoma, and who received chemo-/immunotherapy had higher odds of being treated with SRS (all P < .005). SRS, a more recent primary diagnosis, conjunctive use of chemo/immunotherapy, and luminal A/B breast cancer histologies (all P < .01) correlated with increased survival.

Conclusion:

The use of SRS has increased with patient survival over the last decade. We hypothesize that in addition to SRS-reducing neurotoxicity, this increase is due to guideline relaxation, improved techniques, and increased accessibility. Increased patient survival also indicates a possible relationship between SRS usage and improved survival.

Authors: Khandelwal Saloni , Mahajan Sharad , Paithankar Tushar
Published: August 2024

Temples and heritage corridors have successfully contributed to the redesign of Indian cities, yielding positive outcomes in terms of cultural heritage, tourism, and business. Such projects aid in revitalizing historical districts, preserving traditions, and fostering greater public concern for urban environments. Nevertheless, several challenges persist, such as the risk of commercialization, altering the authentic image or identity of places, social inequality during gentrification, and balancing modernization with conservation. Despite these challenges, these initiatives highlight cultural identity, which should be safeguarded through careful planning to ensure sustainable and inclusive growth. A critical question remains: has the transformation of Indian cities diminished their aesthetic and cultural value? Temple corridors in Indian cities blend Indian culture with contemporary architectural and planning techniques. This paper reviews the development, significance, and evolution of temple corridors within the urban Indian context, focusing on their roles as cultural institutions, social amenities, and tourist attractions.

The Effect of Perceived Usefulness and Perceived Ease of use on Repurchase Intention through the Mediating Variable of Customer Satisfaction in Halodoc Health Application Users
Authors: Ilmiatun Siti , J. Rachbani Didik , . Sugiyono
Published: August 2024

This research investigates the impact of perceived usefulness and perceived ease of use on repurchase intentions through the lens of customer satisfaction as a mediating variable within the realm of the Halodoc Health Application. Employing Partial Least Square Structural Equation Modeling (PLS-SEM) on a cohort of 392 users of Halodoc, the findings reveal that perceived ease of use significantly enhances both customer satisfaction and the intention to repurchase. Contrarily, perceived usefulness initially presents a direct negative influence on repurchase intentions. However, this influence shifts to a positive trajectory when customer satisfaction intervenes as a mediator. Customer fulfillment effectively serves as a complete mediating variable for the link between perceived usefulness and the desire to repurchase, and it also partially mediates the link between perceived ease of use and repurchase intention. This research emphasizes the significance of prioritizing ease of use and customer satisfaction when crafting digital health applications to bolster user fidelity.

Published: August 2024

The assessment of the sagittal skeletal relationship is critically important in orthodontic diagnosis and treatment planning. The Tau angle is used to assess the sagittal skeletal relationship which relies on stable craniofacial landmarks: points T, G, and M. This present study aims to evaluate the reliability of the Tau angle, Beta angle, ANB angle and Wit’s appraisal in assessment of anteroposterior jaw dysplasia thus in future the Tau angle would stand along with other novel sagittal relationship indicators. This study included pretreatment lateral cephalograms of 279 patients, age group 13- 30 years visiting our Department of Orthodontics and Dentofacial Orthopedics of a dental institution. They were grouped into skeletal class I, II and III mal-occlusion depending on Tau angle, Beta angle, ANB angle and Wit’s appraisal. One sample t- test used to determine the differences among the three skeletal patterns. In assessing sagittal relationship, skeletal class I malocclusion would have Tau angle 28 ̊- 34 ̊, Beta angle 27 ̊- 35 ̊, ANB 2=/-2 ̊, Wit’s- AO and BO coinciding in females, BO 1mm ahead of AO in males; Skeletal class II malocclusion would have Tau angle >34 ̊, Beta less than 27 ̊, ANB >4̊ ̊, Wit’s -AO leading BO in females, AO similar to or leading ahead of BO in males; skeletal class III malocclusion would have Tau angle less than 28 ̊, Beta angle < 35 ̊, ANB less than 1, Wit’s BO ahead of AO in females, BO ahead of AO greater than 1mm. The statistical analysis revealed no significant difference in the mean Tau, Beta, ANB angle and Wit’s appraisal values among three groups with those of standard reference values (p ≤ 0.05).

Published: August 2024

We present results from simultaneous far-ultraviolet (FUV) and near-ultraviolet (NUV) observations of T Tauri stars (TTSs) in the Taurus molecular cloud with UVIT/AstroSat. This is the very first UVIT study of TTSs. From the spectral energy distribution of TTSs from FUV to IR, we show that classical TTSs (CTTSs) emit significantly higher UV excess compared to weak-line TTSs (WTTSs). The equivalent blackbody temperatures corresponding to the UV excess in CTTSs (>104 K) are also found to be relatively higher than those in WTTSs (<9250 K). From the UV excess, we have reclassified two WTTSs (BS Tau and V836 Tau) as CTTSs, which has been supported by the follow-up optical spectroscopic study using the Himalayan Chandra Telescope, showing strong Hα line emission. We find that CTTSs show strong excess emission in both the FUV (>107) and NUV (>103) bands, while WTTSs show strong excess only in the FUV (≲105), suggesting that excess emission in the NUV can be used as a tool to classify the TTSs. We also find a linear correlation between UV luminosity (a primary indicator of mass accretion) and Hα luminosity (a secondary indicator of mass accretion) with a slope of 1.20 ± 0.22 and intercept of 2.16 ± 0.70.
Integrated Study of X-Ray Spectrum and Time Lags for HBL Mrk 421 within the Framework of the Multiple-zone Leptonic Model

Published: August 2024

We present the timing analysis of 10 archived XMM-Newton observations with an exposure of >40 ks of Markarian 421. Mrk 421 is the brightest high-frequency-peaked BL Lac object emitting in X-rays produced by electrons accelerated in the innermost regions of a relativistic jet pointing toward us. For each observation, we construct averaged X-ray spectra in 0.5–10 keV band, as well as 100 s binned light curves (LCs) in various subbands. During these observations, the source exhibited various intensity states differing by close to an order of magnitude in flux, with the fractional variability amplitude increasing with energy through the X-ray band. Bayesian power spectral density analysis reveals that the X-ray variability can be characterized by a colored noise, with an index ranging from ∼ −1.9 to −3.0. Moreover, both the standard cross-correlation function and cross-spectral methods indicate that the amount of time lags increases with the energy difference between two compared LCs. A time-dependent two-zone jet model is developed to extract physical information from the X-ray emission of Mrk 421. In the model, we assume that the jet emission mostly comprises a quasi-stationary component and a highly variable one. Our results show that the two-zone model can simultaneously provide a satisfactory description for both the X-ray spectra and time lags observed in different epochs, with the model parameters constrained in a fully acceptable interval. We suggest that shocks within the jets may be the primary energy dissipation process responsible for triggering the rapid variability, although magnetic reconnection cannot be excluded.
Origin of the Twice-90° Rotations of the Polarization Angle in GRB 170114A and GRB 160821A
Authors: Wang Xu , Lan Mi-Xiang , Tang Qing-Wen , Wu Xue-Feng , Dai Zi-Gao
Published: August 2024

The observed abrupt twice-90° rotations of the polarization angle (PA) in the prompt phase of gamma-ray bursts (GRBs) are difficult to understand within the current one-emitting-shell models. Here, we apply a model with multiple emitting shells to solve this new challenging problem. Two configurations of large-scale ordered magnetic fields in the shells are considered: toroidal and aligned. Together with the light curves and the spectral peak energy evolutions, the twice-90° PA rotations in GRB 170114A and GRB 160821A could be well interpreted with the multishell aligned magnetic field configuration (MFC). Our numerical calculations also show that the multiple shells with the toroidal MFC could not explain the observed twice-90° PA rotations. An aligned MFC in the GRB outflow usually indicates the preference of a magnetar central engine, while a toroidal field configuration is typically related to a central black hole. Therefore, the magnetar central engines for the two GRBs are favored.

A Candidate Dark Matter Deficient Dwarf Galaxy in the Fornax Cluster Identified through Overluminous Star Clusters
Authors: Romanowsky Aaron J. , Cabrera Enrique , Janssens Steven R.
Published: August 2024

Two low surface brightness (LSB) dwarf galaxies were identified recently as having little or no dark matter (DM), provoking widespread interest in their formation histories. These galaxies also host populous systems of star clusters that are on average larger and more luminous than typical globular clusters (GCs). We report an initial attempt to identify new candidate DM-deficient dwarfs via their unusual GC systems. Using a large catalog of LSB galaxies from the Dark Energy Survey, we inspect their Dark Energy Camera Legacy Survey (DECaLS) imaging and identify FCC 224 as a candidate found on the outskirts of the Fornax cluster. We analyze the GC system using DECaLS and archival Hubble Space Telescope WFPC2 imaging, and find an apparent population of overluminous GCs. More detailed follow-up of FCC 224 is in progress.
Determination of the Abundance of Mercury from the Hg ii Line at 5677.10 Å in Late B-type Stars. V. HD 174933 (112 Her)
Authors: Monier Richard
Published: August 2024

The weak line of Hg ii located at 5677.10 Å is used to measure the mercury abundance in the HgMn star HD 174933 (112 Her). This line is detected at 3σ above the noise in the adjacent continuum. The synthesis of this line, confirms a large overabundance of mercury, about +4.54 dex, which is less than the excess derived from the 3983.93 Å line in earlier studies. The synthesis of lines in five spectral regions yields estimates of the abundance deficienciess/excesses for twelve other elements. Helium, carbon and magnesium are very depleted, titanium, manganese and iron are moderately overabundant. Strontium, yttrium, zirconium and barium have solar abundances upper limits. Phosphorus, gallium and mercury are very overabundant. The abundance pattern of 112 Her differs from that of other HgMn stars as already stressed in previous studies.
A Comment on the Solar Activity Level in 1744 by Diego de Torres Villarroel
Authors: Aparicio A. J. P. , Vaquero J. M.
Published: August 2024

Solar activity in recent centuries is crucial for astrophysics and geophysics, with historical sunspot records providing key insights, particularly for the 17th and 18th centuries. However, certain periods, such as around 1744, are still poorly understood. This note explores a qualitative commentary on solar activity from that time by Diego de Torres Villarroel, a notable Spanish writer. In his pamphlet on the great comet of 1744, Villarroel observed that the Sun appeared unusually clear, with fewer sunspots and faculae than usual, indicating low solar activity. These observations are consistent with the known solar minimum between cycles −1 and 0 around 1744. While Villarroel’s remarks only offer qualitative confirmation of existing knowledge, they are important for filling in gaps in historical records of solar activity and should be preserved for future research.

On 2022 September 26, the Double Asteroid Redirection Test (DART) mission was the first successful demonstration of a kinetic impactor for planetary defense. The DART mission utilized a novel autonomous data processing pipeline architecture to quickly produce and analyze the quality of raw and calibrated images from the camera mounted on board the spacecraft. Optimization of the data processing pipeline allowed the final 150 images prior to impact to be calibrated and delivered to the Investigation Team and the press within 15 minutes of acquisition. A data quality analysis pipeline allowed for rapid identification of detector misconfigurations, missing data, and other adverse events. DART data products, along with data from LICIACube and data from ground observatories, used common file formats to facilitate the development of analysis and archiving software. This architecture is described for future missions with large volumes of data and an emphasis on quick-turnaround applications such as planetary defense.

Published: August 2024

This research explored the life cycle analysis and environmental cost-benefit assessment of converting ash waste from hospital medical waste incineration into environmentally safe paving block raw materials. The growing concerns about medical waste disposal and its environmental impact necessitate innovative solutions for sustainable waste management. This research aimed to evaluate the feasibility and environmental implications of reusing hospital waste into raw materials for paving block mixtures. This research, a comprehensive life cycle analysis, examined the environmental impacts of medical waste collection for the production and use of paving blocks. Additionally, we conducted an environmental cost-benefit assessment to ascertain the economic feasibility and potential environmental impact forecasts of this recycling approach. The research results show that converting hospital medical waste ash into mixed raw materials for paving blocks not only immobilizes heavy metals but also provides a sustainable alternative for non-building materials. These findings highlight the potential for significant environmental and economic benefits, making this approach a promising strategy for waste management and sustainable construction practices. The cost of preventing environmental damage (eco-cost) in the process of converting ash from the incineration of medical waste into a mixture of raw materials for paving blocks is IDR 600,180.9 per cycle.
Do diversity & inclusion of human capital affect ecoefficiency? Evidence for the energy sector

Published: August 2024

The aim of this study was to assess the impact of diversity and inclusion (D&I) initiatives in workplaces on both financial performance and environmental considerations (referred to as ecoefficiency, ECO). We focused on the energy sector, a significant environmental contributor, and the research spanned from 2016 to 2022, analyzing a broad global sample of 373 firms from 53 countries. ECO was evaluated by integrating environmental scores and conventional financial metrics using data envelopment analysis (DEA).

The findings revealed a significant positive relationship between the collective indicator of diversity, inclusion, people development, and the absence of labor incidents on ECO. Specifically, practices related to workforce diversity, cultural and gender implementation, and investments in employee training and development opportunities were found to be beneficial for ECO. Additionally, we found that these policies impact the environmental component of ECO. However, no significant relationship was observed between practices related to inclusion policies and controversial labors, and ECO.

Furthermore, the results suggested that ECO within the energy sector is influenced by factors such as board size, the integration of environmental, social, and governance (ESG) aspects into executive remuneration, the adoption of a corporate social responsibility (CSR) strategy, alignment with the United Nations (UN) Environmental Sustainable Development Goals (SDGs), and the implementation of quality management systems. Conversely, CEO-chairman duality and the presence of independent board members do not significantly impact ECO in energy companies.

These research findings provide valuable insights and recommendations for industry managers pursuing sustainable business practices, particularly through effective talent management strategies. Additionally, they offer guidance for investors interested in constructing environmentally conscious portfolios.
Chaos detection in predator-prey dynamics with delayed interactions and Ivlev-type functional response
Authors: Liu Qinghui , Zhang Xin
Published: August 2024

Regarding delay-induced predator-prey systems, extensive research has focused on the phenomenon of delayed destabilization. However, the question of whether delays contribute to stabilizing or destabilizing the system remains a subtle one. In this paper, the predator-prey interaction with discrete delay involving Ivlev-type functional response is studied by theoretical analysis and numerical simulations. The positivity and boundedness of the solution for the delayed model have been discussed. When time delay is accounted as a bifurcation parameter, stability analysis for the coexistence equilibrium is given in theoretical aspect. Supercritical Hopf bifurcation is detected by numerical simulation. Interestingly, by choosing suitable groups of parameter values, the chaotic solutions appear via a cascade of period-doubling bifurcations, which is also detected. The theoretical analysis and numerical conclusions demonstrate that the delay mechanism plays a crucial role in the exploration of chaotic solutions.

Han, Oscillation of second order neutral dynamic equations with deviating arguments on time scales, Adv. Differ. Equ., 10 (2018)] were used. The research seeked to provide sufficient criteria that ensured the oscillation of solutions to these complex dynamic equations using a technique Riccati transformations generalized, emphasizing their importance in the study of oscillatory processes within various scientific and engineering contexts.

Integral inequalities in mathematical interpretations are a substantial and ongoing body of research. Because fractional calculus techniques are widely used in science, a lot of research has recently been done on them. A key concept in fractional calculus is the Caputo-Fabrizio fractional integral. In this work, we focus on using the Caputo-Fabrizio fractional integral operator to build a multi-parameter fractional integral identity. Using the obtained integral identity, certain generalized estimates of Bullen-type fractional inequalities have been generated. By establishing certain inequalities, this study advances the fields of fractional calculus and convex function research. Both graphical and numerical statistics are provided to show the correctness of our results. We finally provide applications to modified Bessel functions, $ \mathfrak{h} $-divergence measures, and probability density functions.

Modelos de formação de atletas primam pela ampliação de experiências esportivas, incluindo os eventos esportivos. Assume-se que a variabilidade de propostas incute na vivência de situações paradoxais, importantes na permanência no esporte e/ou vida ativa. Este trabalho discute a percepção da experiência vivida em dois eventos de ginástica para todos com distintos vieses: um com caráter competitivo e outro com caráter demonstrativo. Protagonizaram o estudo 29 crianças participantes de um projeto de extensão universitária. Para a coleta de dados, realizaram-se 8 Grupos Focais, sendo utilizada a Análise Temática. Diários de campo e texto reflexivo do mediador dos GF foram considerados para a triangulação dos dados. Dois eixos foram evidenciados em ambos os eventos: a) aspectos intersubjetivos, cujo comprometimento, o componente estético e a ansiedade perpassaram ambos os eventos e a superação e o nervosismo tiveram maior destaque na competição; e b) inter-relações pessoais, nas quais a importância do outro/grupo foi evidente, com maior relação ao tipo de apresentação coreográfica de grupo, do que especificamente ao tipo de evento. Reconhece-se, então, o fomento a eventos de diferentes naturezas, uma vez que os praticantes de base podem presumir o alto rendimento ou a vida ativa pelo esporte.

The objective of the present review was to analyze the effects of the number of touches on the ball, in the physical and physiological responses during small soccer games. Electronic searches were carried out in the databases: “Web of Science”, “Scopus” and “PubMed”, using the descriptors “Small-sided games”; “Intensity”; “Touches”; “Soccer”; “Soccer players”; “Modified rules”. The PICO strategy was used and the group of words was combined in pairs or trios, using the OR and AND connectors. Only articles published between 2010 and 2022 were considered. The following were excluded: (a) annals and supplements of scientific events, (b) reviews, editorial and instrument validation articles, and (c) studies with women. Of 578 studies, 9 were selected and analyzed. In general, the adoption of the limit rule for touching the ball increased the physiological responses, although discrepancies were observed between the studies regarding the physical responses, we must consider the methodological differences between the studies. We conclude that manipulating the number of touches allowed per ball possession influences players' physiological responses. Specifically, higher intensity is expected in SSGs with fewer ball touches allowed. On the other hand, physical responses are not influenced by this rule.

The aim of the study was to evaluate the impact of five congested matches on the relative intensity, stress symptoms and muscle pain female futsal athletes. Eight female futsal athletes (20.1±3.1 years; 58.6±5.2 kg; 160.0±5.0cm;) were submitted to five successive matches, with a rest interval of approximately 24 hours. The relative match intensity was measured with session rating of perceived exertion. To symptoms of stress was used the daily analysis of life demands in athletes and the visual analog scale of pain was used to assess the muscle soreness perception of the athletes. Friedman's ANOVA was used to compare of the dependent’s variables between the matches, adopting significant value when p <.05. These was increase of the session RPE (χ²(4) = 30.00, p<.05) and relative match intensity (χ²(4) = 31.43, p<.05) through the matches; observed an increase in stress symptoms (χ²(4) = 30.19, p<.05) and muscle soreness (χ²(4) = 29.96, p<.05) also during competition. Successive futsal matches with a short rest interval between them cause great psychophysiological stress, demonstrating an increase in the relative intensity, stress symptoms and perception of muscle soreness.

O presente estudo teve como objetivo avaliar o efeito do German Volume Training (GVT) na variabilidade da frequência cardíaca (VFC) nas diferentes fases do ciclo menstrual (CM) em mulheres jovens com experiencia em treinamento resistido. Métodos: Nove mulheres (idade: 25,88±3,13 anos), realizaram dez series (German Volume Training – carga 80% 1RM) até a falha concêntrica com 1 minuto de intervalo no Leg Press 45°. As fases do CM foram determinadas utilizando: aplicativo Flo flem®, concentração sanguínea estrogênio e progesterona, e Clearblue Digital (ovulação). A VFC foi coletada antes do GVT, imediatamente após, 24 e 48 horas após. A VFC foi analisada nos domínios do tempo (FC; SDNN; RMSSD e PNN50) e frequência (LF; HF e LF:HF). Resultados: As concentrações de progesterona foram maiores (p = 0,0001) na fase lútea. A carga do teste 1RM foi maior na fase lútea quando comparado com a fase folicular: 174,67±53,89 kg e 167,67±48,74 kg, respectivamente (p = 0,0065). A VFC não demonstrou diferença estatística entre as fases do CM (p > 0,05). Não foi observado diferença estática analisando 24 e 48 horas após (p > 0,05). Conclusão: Não houve diferença na performance e na VFC entre as fases do CM.
Short-term changes in spinal cord excitability after backward walking with and without body weight support

Walking is a simple and cost-effective tool for rehabilitation. It decreases spinal cord reflex excitability and might be useful for minimizing symptoms associated with spasticity, which is common in certain diseases such as multiple sclerosis. Particularly, walking in relatively challenging condition presents stronger effects than a typical forward walking. Additionally, body weight support during gait might be suitable for patients with impaired locomotion. However, there is no available data of short-term spinal cord neuroplasticity after backward walking (BW) with or without weight relief. The present study showed a significant reduction in H-reflex amplitude (the electrical analog of the stretch reflex) after 20 min of BW over a treadmill, with or without 20% of body weight support (p<0.05). It was also detected a significant shift of the recruitment curve (RC) to the right in both conditions, indicating that increased stimulus intensity is needed for reflex activation (p<0.05). No significant difference was detected in both H-reflex amplitude and stimulus intensities after 45 min from the ending of the walking task. The short-term after-effects were not associated with presynaptic inhibition of Ia terminals, suggesting that the presynaptic mechanism acting on Ia afferent terminals might not mediate the reduction in reflex excitability.
A Study of Process Interruptions during Pre- and Post-Buffer Layer Epitaxial Growth for Defect Reduction in 4H SiC

Published: August 2024

We perform epilayer growth where the process is interrupted (in situ) during post and pre buffer layer growth at a reduced temperature. Process interrupted during post buffer layer growth demonstrates significant reduction in basal plane dislocation (BPD) at a lower temperature. SIMS study demonstrates that etching takes place during the interruption time. We believe surface treatment of the buffer layer at different etching conditions during the interruption plays a major role in BPD reduction. However, the in-situ interruption, taking place prior to the buffer layer (i.e., on the substrate), does not contribute to the reduction in BPD in epilayer. We believe that the surface effect of interruption related etching on substrate during pre-buffer layer interruption, is not efficient enough to reduce BPD due to the higher doping and higher BPD associated with the substrate. Furthermore, we demonstrate that post buffer layer growth interruption contributes to the reduction in stacking faults in the epilayers. We also attribute this reduction of SF due to the surface etching prior to the drift layer growth.
