In–situ strain control in epitaxial silicon carbide compound semiconductor
Authors: Jazizadeh Behzad , Myronov Maksym 
Published: December 2024

AbstractResidual strain in an epilayer grown on a foreign wafer induces epiwafer’s bow, that is often considered undesirable. Wafer bow however, can be advantageous because both the direction and magnitude of strain are vital for the fabrication of various Micro Electro Mechanical Systems (MEMS), such as resonators. Here strain control is reported for highly mismatched heteroepitaxy of cubic silicon carbide (3C–SiC) compound semiconductor on silicon (Si), a prized functional material, dependent solely on carbon to silicon ratio (C/Si) during growth. While Si–rich condition enhances growth and generates positive curvature i.e. tensile strain, C–rich condition suppresses growth and produces negative curvature i.e. compressive strain. An optimum region emerges with virtually no strain and superior crystallinity. Our findings are significant for the knowledge of heteroepitaxy of 3C–SiC and may be broadened to heteroepitaxy of other compound semiconductors.

AbstractPatients with diabetes mellitus (DM) and chronic kidney disease (CKD) exhibit an elevated risk for cardiac arrhythmias, such as bradycardia, which may potentially lead to sudden cardiac death (SCD). While hypoglycemia, defined as a critical drop in glucose levels below the normal range, has long been associated with adverse cardiovascular events, recent studies have highlighted the need for a comprehensive reevaluation of its direct impact on cardiovascular outcomes, particularly in high-risk populations such as those with DM and CKD. In this study, we investigated the association between glucose levels and bradycardia by simultaneously monitoring interstitial glucose (IG) and ECG for 7 days in insulin-treated patients with DM and CKD. We identified bradycardia episodes in 19 of 85 patients (22%) and associated these episodes with personalized low, medium, and high relative glucose levels. Our analysis revealed a significant increase in bradycardia frequency during periods of lowest relative glucose, particularly between 06:00-09:00 and 12:00-15:00. Furthermore, leveraging a Random Forests classifier, we achieved a promising area under the curve (AUC) of 0.94 for predicting bradyarrhythmias using glucose levels and heart rate variability features. Contrary to previous findings, only 4% of bradycardia episodes in our study population occurred at glucose levels of 70 mg/dL or lower, with 28% observed at levels exceeding 180 mg/dL. Our findings not only highlight the strong correlation between relative glucose levels, heart rate parameters, and bradycardia onset but also emphasize the need for a more personalized definition of hypoglycemia to understand its relationship with bradyarrhythmias in high-risk DM and CKD patient populations.
Die equine Piroplasmose: Fallberichte und epidemiologische Situation
in Europa mit Fokus auf Deutschland
Authors: Axt Carla Wiebke , Springer Andrea , von Luckner Jennifer , Naucke Torsten J. , Müller Elisabeth , Strube Christina , Schäfer Ingo 
Published: December 2024

ZusammenfassungDie equine Piroplasmose (EP) wird durch die Erreger Babesia (B.)
caballi und Theileria (T.) equi ausgelöst und
durch Schildzecken übertragen. Innerhalb Europas sind die Erreger vor allem in
den Mittelmeerländern endemisch. Autochthone Infektionen können in Deutschland
aufgrund einzelner Fallberichte über Infektionen ohne Auslandsaufenthalt und der
geographischen Ausbreitung verschiedener Zeckenarten nicht mehr ausgeschlossen
werden. Die beiden vorgestellten Fälle verdeutlichen das Risiko einer Infektion
bei Auslandsreisen in endemische Regionen sowie beim Import von Pferden aus
endemischen Regionen nach Deutschland. Die klinischen Symptome sind oft
unspezifisch, vor allem treten Fieber, Ikterus, Lethargie, Inappetenz,
Gewichtsverlust und Leistungsminderung auf. Hämatologisch sind Anämien typisch.
Auch Thrombozytopenien sind beschrieben. Die Schweregrade der Zytopenien
variieren von gering- bis hochgradig. Zur Diagnosestellung einer Infektion bzw.
eines Erregerkontaktes sind direkte (Polymerase-Kettenreaktion, Mikroskopie von
Blutausstrichen) und indirekte Nachweisverfahren (Antikörpernachweis) verfügbar.
Imidocarb-Dipropionat gilt als Mittel der Wahl zur Therapie der EP. Bei
Infektionen mit B. caballi scheint eine Erregerelimination möglich,
wohingegen Infektionen mit T. equi trotz Therapie oft in einem
lebenslangen Trägerstatus resultieren. Die Prävention beschränkt sich auf die
Kontrolle bzw. Vermeidung von Zeckenkontakt. Neben möglichen schwerwiegenden
klinischen Auswirkungen hat die EP auch weltweit signifikante wirtschaftliche
Folgen auf den Pferdehandel. Nach den Richtlinien der WOAH wird sie als
meldepflichtige Erkrankung eingestuft und die Empfehlung ausgesprochen, jedes
Pferd bei grenzüberschreitenden Reisen nach den jeweiligen nationalen
Bestimmungen serologisch auf die EP zu testen. In Deutschland ist die Erkrankung
aktuell weder melde- noch anzeigepflichtig.

Published: December 2024

Context The guanaco (Lama guanicoe) is one of the four species of South American camels, and is the largest native mammal inhabiting arid and semi-arid environments in South America. Although the guanaco was abundant and widely distributed in the past, currently its density and distribution range are substantially reduced, inhabiting mainly Southern Patagonia in small isolated groups. The decline in guanaco populations is most likely related to the Anthropocene defaunation process that is affecting large mammals in developing countries worldwide, but the extent and causes of these changes are not well understood. Aims To explore both the changes in the distribution of guanaco populations in Northwest Patagonia and the environmental and anthropic factors that shaped the distribution patterns, by employing a long-term perspective spanning from the end of the Late Holocene to present times (i.e. the last 2500 years). Methods We combine archaeological information, ethnohistorical records and current observations and apply Species Distribution Models using bioclimatic and anthropic factors as explanatory variables. Key results Guanaco spatial distribution in Northwest Patagonia changed significantly throughout time. This change consisted in the displacement of the species towards the east of the region and its disappearance from northwest Neuquén and southwest Mendoza in the last 30 years. In particular, the high-density urban settlements and roads, and secondly, competition with ovicaprine livestock (goats and sheep) for forage are the main factors explaining the change in guanaco distribution. Conclusions Guanaco and human populations co-existed in the same areas during the Late Holocene and historic times (16th to 19th centuries), but during the 20th century the modern anthropic impact generated a spatial dissociation between both species, pushing guanaco populations to drier and more unproductive areas that were previously peripheral in its distribution. Implications As with many other large mammal species in developing countries, Northwest Patagonia guanaco populations are undergoing significant changes in their range due to modern anthropic activities. Considering that these events are directly related to population declines and extirpations, together with the striking low density recorded for Northwest Patagonia guanaco populations, urgent management actions are needed to mitigate current human impacts.
Preliminary liquefaction potential investigation of North Lombok sand based on grain size and particle shape

Published: December 2024

Abstract
Liquefaction resistance investigation is an essential geotechnical aspect of development plans, particularly in areas with a history of liquefaction, such as North Lombok. This study aims to understand the liquefaction potential of sand at the liquefaction sites in North Lombok using laboratory testing. The physical properties and microstructure analyses of sand samples from the two liquefaction sites of Pemenang and Beraringan were examined, including grain size, mineralogy, and particle shape parameters. Our results show that the grain size of both sands is within the liquefiable soil criteria. Both sand types are composed of quartz and have a high convexity, illustrating weak inter-grain locking. The overall regularity of the Beraringan sand is also high, which generally correlates with low liquefaction resistance. Thus, it can be concluded that both sands have liquefaction potential based on preliminary laboratory investigations, and therefore, need to be considered in engineering reconnaissance and structural design.

Authors: Thohir M A , Dina H R , April Y F , Habibi  
Published: December 2024

Abstract
Three-dimensional media design is a challenge for pre-service teachers in realizing real learning of abstract physics concepts. Virtual reality (VR) is one of the popular three-dimensional media for design by pre-service teachers. However, the perception of the design is still little revealed. This research explores pre-service teachers’ perception factors when designing using experiential learning to design virtual reality. This study involved 5 pre-service teachers by documenting the design results and interviews. These results are grouped problem problem-oriented and design oriented. The results show differences in the characteristics of problem solving, which are student characteristics and material characteristics. At the same time, the design is oriented to the features of the application used. The implications of technology courses for future teachers are geared toward mature problem-solving and interactive design in VR.

Published: December 2024

Abstract
Some magnetic configurations utilized the Seebeck coefficient in the NiBr2 monolayer. To create some magnetic configurations, the magnetic moments of the Ni atoms were arranged. Once the self-consistent calculations were finished, the Boltzmann transport was used to compute the Seebeck coefficient. The high Seebeck coefficients were observed where the peak of Seebeck coefficients depends on the magnetic configuration near the critical temperature of the NiBr2 monolayer. Based on the plot, the NiBr2 monolayer is foremost for the thermoelectric devices implied.

Published: December 2024

Abstract
The Green synthesis method is an attractive approach to producing nanoparticles due to its environmentally friendly nature and its ability to provide the same quality as conventional ZnO. Zinc oxide nanoparticles (ZnO NPs) were successfully synthesized using garlic (Allium sativum) bulb extract as a reducing agent using the green synthesis method. XRD results showed that the ZnO crystals formed were hexagonal wurtzite, with crystallite sizes of 30.84 and 42.5 nm for ZnO-G10 and ZnO-G20 samples. FTIR results showed the presence of typical ZnO absorption in the region around 440-480 cm−1. The photodegradation of congo red dye was further studied, and the maximum degradation efficiency reached 99.0% for 120 minutes. These results indicate the potential of ZnO material synthesized by the green synthesis method for photocatalyst applications.

Published: December 2024

Abstract
Landslide mitigation is a primary concern in areas with significant elevation gradients. In addition to elevation, vegetation and hydrological factors also influence landslide potential. Therefore, this study analyzes landslide risk using satellite-derived vegetation data (NDVI). The results will be mapped to show relative susceptibility to landslides. The clustering method used is K-Means. NDVI data was obtained from NASA’s Terra and Aqua satellites, and the analysis is based on vegetation levels. The study identifies six areas in Garut where landslides frequently occur. The K-Means clustering process categorizes gridcodes 3 and 4 in the NDVI data as potential landslide zones due to sparse vegetation. The clusters are divided into three groups, with cluster 1 having a silhouette coefficient close to 1, indicating robust clustering. The mapping results highlight the North Garut area as having a high potential for landslides.

Abstract
With the use of aluminum in the transportation sector in Indonesia, reducing the weight of transportation equipment has become one of the most critical issues for manufacturers, who are still trying to reduce the weight of transportation equipment to optimize fuel. 5083 aluminum alloy is a suitable material for making transportation equipment lighter because of its many benefits, such as an excellent strength-to-weight ratio and corrosion resistance. It is ideal for application in the field of marine equipment. This research aims to determine the effect of tool offset variations of 0 mm, 0.2 mm, and 0.4 mm on the tensile strength and hardness of 5083 series aluminum friction stir welding joints. Based on the research that has been carried out, the specimens produce the highest tensile strength values with a tool offset variation of 0.2 mm and a tensile strength value of 218.6 MPa, and the specimens produce the lowest tensile strength values with a tool offset variation of 0.4 mm and a tensile strength value of 127.35 MPa. Meanwhile, the hardness values for each tool offset variation were 92 VHN, 66.75 VHN, and 108.87 VHN, with the fracture of each test specimen being in the weld metal area due to its hardness.

Abstract
This research aims to measure the ability of pre-service physics teachers to create project-based physics learning media that focuses on renewable energy materials based on several leading indicators, namely understanding of the material, safety and affordability, creativity and innovation, technical skills, implementation skills, communication, evaluation skills, and adaptation. This research uses a quantitative descriptive research design with a case study approach with the subject of 27 pre-service physics teacher students at a university in East Java, Indonesia. Research data was collected through project portfolio assessments through products produced, tests, and interviews. The data obtained was analyzed using descriptive statistics. The research results show that for indicators of material understanding, the majority of pre-service physics teachers are at the intermediate level (44.44%), followed by the basic level (29.63%), professional (18.52%), and novice (7.41%). This indicates that pre-service physics teachers have a fairly good understanding of renewable energy and the learning objectives using teaching aids. Regarding safety and affordability indicators, most pre-service physics teachers are at the intermediate level (48.15%), showing adequate ability to ensure that teaching aids are safe and affordable. Pre-service physics teachers dominate indicators of creativity innovation and technical skills at basic (40.74%) and intermediate (29.63%) levels. This shows that pre-service physics teachers still need to improve their abilities in creating interesting, relevant, environmentally friendly, and interactive teaching aids. This improvement is important so pre-service physics teachers can be more effective in designing teaching aids with functional and aesthetic designs and using simple technology such as paper, cardboard, recycled materials, or essential digital tools.
