Investigation on the Degradation Mechanism of Si/SiC Cascode Device Under Repetitive Short-Circuit Tests

The Si/SiC Cascode device has been widely accepted in various applications, however, its reliability issue still remains a major concern and needs to be extensively investigated. In this paper, the degradation of a 750 V Si/SiC Cascode device under repetitive short-circuit (SC) tests is investigated at 400 V DC-link voltage. Static and dynamic characteristics are measured before and after the repetitive SC cycles. As the SC cycle increases, the degradation of the device becomes gradually significant. By linking changes in electrical properties to metallization degradation, the physical mechanism of device degradation has been uncovered in depth. Experimental results show that the continuous stress under repetitive SC cycle leads to an increase in the on-state resistance of Si/SiC Cascode device. Finite-element-model (FEM) simulations show that due to the pad current crowding in the source region, the source Al metallization temperature of the SiC JFET rapidly increases to the melting point and undergoes reconstruction, resulting in a significant increase in the source Al metallization resistance. In addition, it is found by scanning electron microscopy (SEM) that the gate metal aluminum of SiC JFET chip also undergoes reconstruction, which is the reason for the degradation of the dynamic characteristics. The research in this paper will provide useful evidences for device manufactures to design Si/SiC Cascode device with high reliability.
The Stochastic Dynamics of Biomass and Soil Moisture in Water-Limited Ecosystems

This dissertation examines the interaction between soil moisture and vegetation when the system is driven by intermittent, limited rainfall, resulting in a stochastic process. The first chapter introduces analytical techniques for describing this interaction, including a novel solution for the joint probability distribution of biomass and soil moisture. The second chapter applies these techniques to a field site in NW China, and demonstrates that such a model accurately reproduces the observed variability in vegetation over multiple growing seasons. Specifically, it is shown that water is the dominant driver of growth, and that the variability in rainfall can be accurately mapped onto the measured variability in leaf and root biomass via the model given here. The third chapter is devoted to understanding the structures which can arise in the distribution of vegetation in the presence of strong feedbacks with the soil water balance. This culminates in the emergence of bi-modal and multi-modal distributions, along with the conditions under which they occur and new mathematical approaches for describing them, such as exact results for the crossing times between high and low biomass modes. The fourth and final chapter introduces some preliminary work on the application of this model to multi-species ecological competition, namely that between plant species with different transpiration characteristics competing for the same rainfall.

Online pain neuroscience education and graded exposure to movement in breast cancer survivors: protocol of a randomized controlled trial

Introduction Cancer-related chronic pain is an important sequelae that damages the quality of life of breast cancer survivors. Pain neuroscience education and graded exposure to movement are therapeutic tools that have been shown to be effective in the management of chronic pain in other populations. However, there are no previous studies that combine them after breast cancer. Objective To evaluate the effectiveness of an online physiotherapy focused-person program which combines pain neuroscience education and graded exposure to movement for quality of life improvement in breast cancer survivors. Methodology This protocol is a randomized controlled trial with a sample size of 40 breast cancer survivors with pain in the last 6 months. Participants will be allocated to the experimental or control group using a fixed size block randomization method. The evaluator and statistician will be blinded to participant allocation. Participants in the experimental group will receive a 12-week intervention based on pain neuroscience education and therapeutic yoga as a graded exposure to movement exercise; participants in the control group will continue with their usual cancer-related symptoms care. Both groups will receive an education booklet. The main outcome will be quality of life, measured by the Functional Assessment of Cancer Therapy – Breast (FACT–B+4); secondary, four outcomes related to pain experience (catastrophising, self-efficacy, kinesiophobia and fear-avoidance behaviors) will be also assessed. All variables will be assessed by two blinded evaluators at four timepoints. A mixed-model analyses of variance ANOVA (2 × 4) will be used to study the effects of the treatment on the dependent variables. All statistical tests will be performed considering a confidence interval of 95%. SPSS program will be used for the data analysis.

Gender Dynamics in Climate Change, Mitigating Mechanisms and Outcome: Evidence from Women Farmers in Muyuka, Cameroon

Climate change is not a new phenomenon in Cameroon but its ramifications and dynamics are still challenging. Women food crop farmers continue to experience high postharvest losses, food insecurity, increased poverty and low family nutrition. They increasingly remain vulnerable to climate change compared to men because of their gender which limit their access to social and economic resources. Consequently, agriculture which is a traditional mainstay for women and reliable recourse to livelihood is jeopardized. Meanwhile government’s effort has been loudly minimal. To mitigate impacts of climate change, women inspite of limited education and income have taken the front line, adopting local techniques through group action. Specifically, women anticipate or update their expectation of the climate in response to unusual weather patterns by altering agricultural calendars, applying manure and farming in marshy areas. These adaptation strategies have not restored agricultural reputation. Family nutritional intake and women’s income remain low. This paper examines the challenges of climate change on food production and local adaptation mechanisms by women food producers in Cameroon. 100 women farmers in three quarters of Muyuka were randomly selected for this study which adopted a descriptive design. Questionnaires, interviews and focus group discussions were used to elicit valid responses which were analysed both quantitatively and qualitatively. Women’s voices and gender sensitive policies are imperative in climate-Smart socio-economic development and to achieve agricultural needs in Cameroon’s vision 2035. Keywords: gender, climate change, mitigating mechanisms, women farmers and Cameroon
Spontaneous hybridization among invasive Poaceae in Hawai‘i: Chloris × pseudosagrana nothosp. nov. and Cenchrus × peregrinus nothosp. nov.

During grass surveys across the islands of Hawai‘i in 2022, two novel hybrids among non-native Poaceae were found growing on roadsides. Spontaneous hybridization was observed among Chloris barbata and C. divaricata on O‘ahu and among Cenchrus clandestinus and C. setaceus on Hawai‘i island. Morphological evidence initially suggested these plants may be hybrids and molecular analysis using the ITS and rpl32-trnL regions confirmed that the plants are hybrids and identified their parentage. These hybrids are named Chloris × pseudosagrana nothosp. nov. and Cenchrus × peregrinus nothosp. nov. No developed seeds could be found on either of these hybrids and they are suspected to be sterile F1 hybrids. The occurrence of hybridization events among other non-native species are also discussed.
Statistical Properties of Aftershocks for Ahar-Varzeghan Twin Earthquakes on 11 August 2012, NW Iran, and Investigation of Seismicity of North Tabriz Fault

Two earthquakes occurred on 11 August 2012 in East Azerbaijan province, NW Iran with Mw 6.3 at 12:23:15.9 and Mw 6.1; 11 minutes after the first shock at 12:34:34.8 GMT time. In this study, we concentrated on the properties of the aftershock sequences in a duration of 7.5-month time-period data after the main shocks, recorded by Broadband Iranian Network (BIN). We obtained p, c and K parameters with the maximum likelihood method and the occurrence rate was modeled by the modified Omori formula. Besides, we showed that aftershocks of the aftershock in 7 Nov. 2012 (M = 5.6) also decay according to the modified Omori law. We investigated the spatial and temporal variations of b-values before and after the twin earthquakes with Mw 6.3 and Mw 6.1 approximately 20 km around North Tabriz Fault (NTF) in the region from 1996 to 2013 using Iranian Seismological Center (IRSC). We believed that a research of the past 17 years has clearly established that spatial b-value changes and seismicity rate are highly significant and meaningful. Moreover, our research led to a warning for a probable strong motion along NTF for the coming couple of years.
Identification of MicroRNA Profiles in Fetal Spina Bifida: The Role in Pathomechanism and Diagnostic Significance

Distinct miRNA expression patterns may reflect anomalies related to fetal congenital malformations such as spinal bifida (SB). The aim of this preliminary study was to determine the maternal miRNA expression profile of women carrying fetuses with SB. Therefore, six women carrying fetuses with SB and twenty women with euploid healthy fetuses were enrolled in this study. Using NanoString technology, we evaluated the expression level of 798 miRNAs in both plasma and amniotic fluid samples. A downregulation of miR-1253, miR-1290, miR-194-5p, miR-302d-3p, miR-3144-3p, miR-4536-5p, miR-548aa + miR-548t-3p, miR-548ar-5p, miR-548n, miR-590-5p, miR-612, miR-627-5p, miR-644a, and miR-122-5p, and an upregulation of miR-320e, let-7b-5p, miR-23a-3p, miR-873-3p, and miR-30d-5p were identified in maternal amniotic fluid samples in SB when compared to the control group. The target genes of these miRNAs play a predominant role in regulating the synthesis of several biological compounds related to signaling pathways such as those regulating the pluripotency of stem cells. Moreover, the maternal plasma expression of miR-320e was increased in pregnancies with SB, and this marker could serve as a valuable non-invasive screening tool. Our results highlight the SB-specific miRNA signature and the differentially expressed miRNAs that may be involved in SB pathogenesis. Our findings emphasize the role of miRNA as a predictive factor that could potentially be useful in prenatal genetic screening for SB.

Key Committing Attacks against AES-based AEAD Schemes

Recently, there has been a surge of interest in the security of authenticated encryption with associated data (AEAD) within the context of key commitment frameworks. Security within this framework ensures that a ciphertext chosen by an adversary does not decrypt to two different sets of key, nonce, and associated data. Despite this increasing interest, the security of several widely deployed AEAD schemes has not been thoroughly examined within this framework. In this work, we assess the key committing security of several AEAD schemes. First, the AEGIS family, which emerged as a winner in the Competition for Authenticated Encryption: Security, Applicability, and Robustness (CAESAR), and has been proposed to standardization at the IETF. A now outdated version of the draft standard suggested that AEGIS could qualify as a fully committing AEAD scheme; we prove that it is not the case by proposing a novel attack applicable to all variants, which has been experimentally verified. We also exhibit a key committing attack on Rocca-S. Our attacks are executed within the FROB game setting, which is known to be one of the most stringent key committing frameworks. This implies that they remain valid in other, more relaxed frameworks, such as CMT-1, CMT-4, and so forth. Finally, we show that applying the same attack techniques to Rocca and Tiaoxin-346 does not compromise their key-committing security. This observation provides valuable insights into the design of such secure round update functions for AES-based AEAD schemes.
Estratégias na composição de blends no mercado internacional de café: uma análise de cointegração

Since the 90’s , the international coffee market has undergone changes driven by the inclusion of Vietnam, R obusta coffee producer , which is less valued in the marketplace than the Natural and Mild Arabica types . These changes have raised questions about the behavior of buyers relative to the strategy of composition of coffees from different origins. This article sought to examine the relationship between prices of the three main varieties of coffee commercialized in order to provide evidence relative to companies' strategies regarding the use of coffees from different origins for the composition of blends. To this end, cointegration analysis was performed . It was observed that the result is consistent with the practices employed by the market , that is, companies tend to modify the blend according to the price differential , when considering two different types of origins. This strategy demonstrates the intense price competition which has significant impacts on coffee producers.
Temperature-Dependent Thermal Impedance Measurement of GaN-Based HEMTs Using Transient Thermoreflectance

The transient thermal response of GaN high-electron-mobility transistors (HEMTs) is studied using transient thermal thermoreflectance (TTR) measurements. The change in the thermal impedance at various ambient temperatures is observed and analyzed using finite-element (FE) simulation and thermal equivalent circuits. A temperature-dependent Cauer model has been implemented for predicting the transient temperature response of the device under test (DUT), applicable to arbitrary power dissipations or ambient temperatures. This work provides a practical way for determining or verifying transient thermal models of GaN-based HEMTs using RC networks.
Treatments for Cannabis Use Disorder across the Lifespan: A Systematic Review

Cannabis use disorder (CUD) is a growing public health concern, with rising prevalence and significant impact on individuals across age groups. This systematic review examines 24 studies investigating pharmacological and non-pharmacological interventions for CUD among adolescents (up to 17), young adults (18–24), and older adults (25–65). Database searches were conducted for randomized controlled trials of CUD interventions reporting outcomes such as cannabis use, abstinence, withdrawal symptoms, and treatment retention. For adolescents, interventions such as contingent rewards and family engagement have shown promise, while young adults benefit from technology-based platforms and peer support. In older adults, pharmacological adjuncts combined with counseling have shown promise in enhancing treatment outcomes. However, optimal treatment combinations remain uncertain, highlighting the need for further research. Addressing CUD requires tailored interventions that acknowledge developmental stages and challenges across the lifespan. Although promising interventions exist, further comparative effectiveness research is needed to delineate the most efficacious approaches.

Life-Threatening Hemoptysis Leading to Suffocation

Hemoptysis represents a symptom or sign that typically causes anxiety for patients and draws the attention of the physician because it can be caused by various conditions, ranging from benign to malignant. Depending on the amount of coughed-up blood, hemoptysis can be a life-threatening condition. We present the case of a female patient with a life-threatening hemoptysis that was caused by underlying bronchiectasis and antiplatelet and anticoagulant treatments. A large blood clot was extracted from the patient’s airways using a rigid bronchoscope. Hemoptysis is a significant symptom that should be taken seriously, regardless of its size. Massive hemoptysis is an emergency condition in respiratory medicine, which requires immediate management in adequately equipped centers.
Studying the Effect of MBNL1 and MBNL2 Loss in Skeletal Muscle Regeneration

Loss of function of members of the muscleblind-like (MBNL) family of RNA binding proteins has been shown to play a key role in the spliceopathy of RNA toxicity in myotonic dystrophy type 1 (DM1), the most common muscular dystrophy affecting adults and children. MBNL1 and MBNL2 are the most abundantly expressed members in skeletal muscle. A key aspect of DM1 is poor muscle regeneration and repair, leading to dystrophy. We used a BaCl2-induced damage model of muscle injury to study regeneration and effects on skeletal muscle satellite cells (MuSCs) in Mbnl1∆E3/∆E3 and Mbnl2∆E2/∆E2 knockout mice. Similar experiments have previously shown deleterious effects on these parameters in mouse models of RNA toxicity. Muscle regeneration in Mbnl1 and Mbnl2 knockout mice progressed normally with no obvious deleterious effects on MuSC numbers or increased expression of markers of fibrosis. Skeletal muscles in Mbnl1∆E3/∆E3/ Mbnl2∆E2/+ mice showed increased histopathology but no deleterious reductions in MuSC numbers and only a slight increase in collagen deposition. These results suggest that factors beyond the loss of MBNL1/MBNL2 and the associated spliceopathy are likely to play a key role in the defects in skeletal muscle regeneration and deleterious effects on MuSCs that are seen in mouse models of RNA toxicity due to expanded CUG repeats.
A 3 D- FEM Study on the Stress Distributions in Pediatric Skull due to Impact from Free Fall

Brain is vulnerable to injuries even from low heights of fall. There are many infant casualties who get severe brain injury each year. This research is a simulated study of the stress patterns and values when human infant skull is subjected to free fall. The input velocity was calculated using simple free fall velocity formulas and was fed into the simulation. Model was meshed and refined using Hypermesh software. RADIOSS solver of the Hyperworks package was used to analyze and draw results for the simulation process. Various types of stresses and strains were extracted and plotted against respective drop heights.
A one dimensional coupled air-sea model for diagnostic studies during Toga Coare

A process-oriented diagnostic model has been developed, which couples an atmospheric column model to an upper ocean model. In vertical structure and representation of physical processes, the atmospheric model resembles a single horizontal grid point of a general circulation model. It includes vertical transports by convection and turbulent mixing, radiative transfer with interactive clouds, and a complete hydrologic cycle. The ocean model is a simple mixed layer, synchronously coupled to the atmosphere through a surface energy budget computation. Time-dependent observational analyses of horizontal atmospheric transports of momentum, heat and moisture are used to force the coupled model. The model then produces such fields as temperature, humidity, cloudiness and diabetic heating rate components, all as functions of height and time. Sample integrations of the model for test cases in the 1979 Indian summer monsoon onset are presented and verified against observations. These diagnostic analyses suggest that this type of model may be useful in TOGA COARE for applications such as interpretation of results from multidimensional models, validation of surface flux data, and estimation of sensitivity to alternative physical processes. It may also be used to aid in designing the intensive field phase of TOGA COARE by means of numerical observing system simulation experiments.
