Stable High Temperature Operation of p-GaN Gate HEMT With Etch-Stop Layer

High-temperature operation of the p-GaN gate high-electron-mobility transistor (HEMT) was investigated, specifically up to 500 °C. The p-GaN gate HEMT demonstrated stable behavior with normally-off operation, steep increase of drain current in the subthreshold region, and suppressed off-state current. By adding Al2O3 etch-stop layer, the device showed significant reduction in subthreshold swing when measured at 500 °C, effectively mitigating hysteresis in the transfer characteristics. Additionally, the lifetime of the gate stack with the etch-stop layer was estimated to be much longer than that of the stack without the etch-stop layer. Through the integration of the depletion-mode (D-mode) metal-insulator-semiconductor HEMT (MIS-HEMT) device with the p-GaN gate device, a direct-coupled field-effect transistor logic (DCFL) inverter was fabricated. This inverter showed stable logic operation up to 500 °C, featuring rail-to-rail operation and large gain. A long-term reliability test conducted at 500 °C for 100 hours revealed stabilized on-state and off-state values after about 50 hours of operation.
The Research in the Distributed Wireless Measurement and Recording System Based on Synchronous Acquisition Technique for Start Debugging Process of EHV/UHV Transformer Substation

Due to the low efficiency of preparation, long-distance electrical wiring easily causing safety accidents and difficult to correlate the current and voltage signal data during the start debugging process of UHV/EHV transformer substation, a set of high-precision distributed wireless measurement and recording system for multiple nodes is developed. The current and voltage signals of the substation are collected by each node, and the clock synchronization is realized by using GPS/BD synchronous timing. Then the signal is transmitted wirelessly to the upper computer to realize the transient state waveform recording and other functions. The test shows that the sampling rate of the system can reach more than 200ksps, and it can obtain the transient waveform and equipment state of each site not only in real time but intuitively.
Analyse spatiale d'une zone alluviale par une nouvelle méthode de fusion d'images SPOT multispectrales (XS) and SPOT panchromatique (P)

La fusion des images SPOT XS et SPOT P est devenue une technique utile a de nombreuses thematiques. En effet, la haute resolution spectrale des images XS combinee a la haute resolution spatiale de l'image P permet une meilleure analyse de l'espace et de l'occupation des sols (exemple d'une plaine inondable d'un cours d'eau du piedmont alpin). Les methodes de fusion couramment utilisees ne donnent pas entiere satisfaction; elles deteriorent les proprietes spectrales des images XS, ce qui rend l'exploitation qualitative de l'image fusion resultante tres delicate. Une methode qui permet de simuler des images XS a 10 m tout en conservant les proprietes spectrales des images XS d'origine a 20 m est presentee ici (.)

Deep Red Photoluminescence from Cr3+ in Fluorine-Doped Lithium Aluminate Host Material

Deep red phosphors have attracted much attention for their applications in lighting, medical diagnosis, health monitoring, agriculture, etc. A new phosphor host material based on fluorine-doped lithium aluminate (ALFO) was proposed and deep red emission from Cr3+ in this host material was demonstrated. Cr3+ in ALFO was excited by blue (~410 nm) and green (~570 nm) rays and covered the deep red to near-infrared region from 650 nm to 900 nm with peaks around 700 nm. ALFO was a fluorine-doped form of the spinel-type compound LiAl5O8 with slightly Li-richer compositions. The composition depended on the preparation conditions, and the contents of Li and F tended to decrease with preparation temperature, such as Al4.69Li1. 31F0.28O7. 55 at 1100 °C, Al4.73Li1. 27F0.17O7. 65 at 1200 °C, and Al4.83Li1. 17F0.10O7. 78 at 1300 °C. The Rietveld analysis revealed that ALFO and LiAl5O8 were isostructural with respect to the spinel-type lattice and in a disorder–order relationship in the arrangement of Li+ and Al3+. The emission peak of Cr3+ in LiAl5O8 resided at 716 nm, while Cr3+ in ALFO showed a rather broad doublet peak with the tops at 708 nm and 716 nm when prepared at 1200 °C. The broad emission peak indicated that the local environment around Cr3+ in ALFO was distorted, which was also supported by electron spin resonance spectra, suggesting that the local environment around Cr3+ in ALFO was more inhomogeneous than expected from the diffraction-based structural analysis. It was demonstrated that even a small amount of dopant (in this case fluorine) could affect the local environment around luminescent centers, and thus the luminescence properties.

Growth and transcriptional response of wheat and rice to the tertiary amine BMVE

Introduction Seed vigor is largely a product of sound seed development, maturation processes, genetics, and storage conditions. It is a crucial factor impacting plant growth and crop yield and is negatively affected by unfavorable environmental conditions, which can include drought and heat as well as cold wet conditions. The latter leads to slow germination and increased seedling susceptibility to pathogens. Prior research has shown that a class of plant growth regulators called substituted tertiary amines (STAs) can enhance seed germination, seedling growth, and crop productivity. However, inconsistent benefits have limited STA adoption on a commercial scale Methods We developed a novel seed treatment protocol to evaluate the efficacy of 2-(N-methyl benzyl aminoethyl)-3-methyl butanoate (BMVE), which has shown promise as a crop seed treatment in field trials. Transcriptomic analysis of rice seedlings 24 h after BMVE treatment was done to identify the molecular basis for the improved seedling growth. The impact of BMVE on seed development was also evaluated by spraying rice panicles shortly after flower fertilization and subsequently monitoring the impact on seed traits. Results BMVE treatment of seeds 24 h after imbibition consistently improved wheat and rice seedling shoot and root growth in lab conditions. Treated wheat seedlings grown to maturity in a greenhouse also resulted in higher biomass than controls, though only under drought conditions. Treated seedlings had increased levels of transcripts involved in reactive oxygen species scavenging and auxin and gibberellic acid signaling. Conversely, several genes associated with increased reactive oxygen species/ROS load, abiotic stress responses, and germination hindering processes were reduced. BMVE spray increased both fresh and mature seed weights relative to the control for plants exposed to 96 h of heat stress. BMVE treatment during seed development also benefited germination and seedling growth in the next generation, under both ambient and heat stress conditions. Discussion The optimized experimental conditions we developed provide convincing evidence that BMVE does indeed have efficacy in plant growth enhancement. The results advance our understanding of how STAs work at the molecular level and provide insights for their practical application to improve crop growth.
APTAMERS: NANOMATERIALS AS A POTENTIAL AGENT FOR ANTIVIRAL THERAPEUTIC DRUG DELIVERY DEVELOPMENT: A SYSTEMATIC LITERATURE REVIEW

Chemotherapeutic experts have been utilised to cure a variety of disorders, but their practical application is restricted due to their regrettable selectivity and outrageous fundamental optional effects. Short single-stranded DNA or RNA oligonucleotides known as aptamers are released from randomised libraries and have strong propensity and differentiation towards targets like antibodies as well as characterised structures and ties to targets like proteins. They commonly suppress protein interactions while restricting proteins, which may elicit positive effects like threat. Aptamers have recently demonstrated their amazing promise for use in medicines, biosensors, and bioimaging thanks to a number of advantages, such as minimal immunogenicity, simplicity of giant degree blend, low pack to-bunch collection, genuinely substance modification, and programmability. At any rate, the steady for the most part accomplishment speed of aptamer is far from being brilliant, despite everything needs to overwhelm the gigantic obstruction in propensity, constancy for utilitarian application, explicit illness cell affirmation. The sensible method of controlling the binding execution of aptamers and dealing with their show in the practical application is of great significance and these single-abandoned DNA or RNA aptamers could outline with astoundingly poisonous chemotherapy drugs, hurts, strong RNAs or different particles as novel aptamer-drug structures, which are prepared to do endlessly out working on the obliging plentifulness and decreasing the critical danger of solutions and have unprecedented possible in living spaces for appointed ailment treatment. In this survey, we have extensively covered and summarised the ongoing improvements in the aptamer-drug structure philosophy for designated drug transport in the assessment methodologies of aptamers for unambiguous disease biomarkers. A modified strategy utilising aptamers could be a reliable system for quick and precise advancement of biopharmaceutics for use in infection-related treatment, especially in light of the enormous advances in modernised thinking for protein and RNA structure conjectures. Additionally, the likelihood of future conception is also summarised.
Darkling beetles (Coleoptera: Tenebrionidae) of forest sites and agricultural fields in the south Western Ghats (South India)

Data on the abundance, feeding guilds, flightlessness and endemic status of darkling beetles from selected forest sites and agriculture fields in the moist south Western Ghats in south India are provided. Overall abundance, diversity and evenness were higher in agriculture fields than in forest. Luprops tristis was the major species in agriculture field and Gonocephalum bilineatum in forest. Mycetophagous and detritivorous guilds were reported from the agriculture fields and detritivorous guild alone from the forests. Epigean, subterranean, corticolous, dung associated and mycetophagous darkling beetles were present in agriculture fields in contrast to the record of epigean and subterranean forms in forests. Higher abundance of flightless platynotine genus Menearchus, endemic to the Indian subcontinent in the agricultural field is attributed to the decaying organic matter availability in the open, dry environment conditions in agriculture field.
Operation model of a skew-symmetric split-crystal neutron interferometer

The observation of neutron interference using a triple Laue interferometer formed by two separate crystals opens the way to the construction and operation of skew-symmetric interferometers with extended arm separation and length. The specifications necessary for their successful operation are investigated here. In contrast with previous studies, both incoherent sources and the three-dimensional operation of the interferometer are considered.
Near-bed hydrodynamics and sediment transport in tidal channels and on tidal flats

Near-bed hydrodynamics, sediment suspension, erosion, and deposition were investigated in tidal channels, on a tidal flat, and in man-made ditches within tidal marshes. Highly resolved velocity profiles were measured in the lower 0.03 m of the water column in small tidal channels using acoustic Doppler profiling velocimeters. Three methods to estimate bed shear stress were compared. The Reynolds stress method and turbulent kinetic energy (TKE) derived stress method gave similar results, while the log-law method gave poor results. Shear stresses and turbulent kinetic energy followed a similar trend with the largest peaks during ebb tide. The fluid stress during flood tide was on average approximately 30 % of the fluid shear stress during ebb tide. Turbulence dissipation was estimated using the frequency spectrum and structure function methods, which resulted in similar turbulence dissipation estimates. Turbulence production exceeded turbulence dissipation at every phase of the tide, suggesting that advection and vertical diffusion are not negligible. However, turbulence production and dissipation were within a factor of 2 for 77 % of the estimates. Data collected in small tidal channels intersecting a tidal flat indicated that the channel velocity peaked when the water level was near the tidal flat level. Maximum water depth at the field site varied from 0.11 m during the lowest neap high tide to 0.58 m during a storm event. In the channel intersecting the tidal flat, the shear stress, turbulence, and along-channel velocity were ebb dominant; e.g. 0.33 m/s peak velocity for ebb compared to 0.19 m/s peak velocity for flood. Distinct pulses in velocity occurred when the water level was near the tidal flat level. The velocity pulse during flood tide occurred at a higher water level than during ebb tide. No corresponding velocity pulse on the tidal flat was observed. Sediment concentrations peaked at the beginning and end of each tidal cycle, and often had a secondary peak close to high tide, assumed
Charles Sanders Peirce and Effective Altruism

Abstract:When confronted with moral dilemmas, Charles S. Peirce would recommend that we trust our sentiments, not our reasoning. A scientific exploration of ethics may affect our daily conduct but should only do so gradually. Some modern approaches take the opposite stance and deny the significance of moral sentiments. Considering both Peirce and his opponents, I aim to contribute to the discussion of a radical moral theory: effective altruism. Stating that we should strive to do the most objective good we can, effective altruism regularly conflicts with our moral sentiments. In response, effective altruists claim that our sentiments are misguided and should be overcome. Which side is right? Using Peirce's work to answer this question reveals that effective altruism cannot clearly define how it aims to affect our daily conduct. In addition, it seeks to change our sentiments, but may alter them for the worse. Taking Peirce's insights seriously leads us to conclude that we should be cautious of how we adopt effective altruism in our lives—and that while we deliberate this, we should instead trust our sentiments.
The Role of Exterior Paints in Enhancing Energy Efficiency: An Analysis of Buildings in Cities

Energy efficiency has become a significant issue in the construction industry today. Reducing the energy consumption of buildings is a crucial step to provide environmental sustainability and economic advantages. In this context, the impact of exterior paints on energy efficiency is being examined to determine how they can be used to reduce the energy consumption of structures. A study conducted in the cities of Ankara, Antalya, Istanbul, Izmir, Kars, Kayseri, Konya, Mersin, and Tokat has developed a model for energy efficiency analysis. In this study, the absorptance values of external facades for each city were adjusted to 0.1, 0.4, and 0.7 using different types of paints. The building under investigation was chosen to have a U-value of 0.28 W/(m² °C) and an R-value of 20 h. ft²°F/Btu. Building models with these paint values were created using the Energy 3D program, and separate analyses were conducted to evaluate them. The aim of the study is to examine the impact of colors used in exterior paints on the energy efficiency of buildings in cities. Therefore, models were created using different absorptance values of paints. The results obtained were evaluated separately for each city. Analyses revealed differences in energy consumption for buildings painted with different types of paint. Exterior facades with low absorptance values reflect sunlight and keep the interior temperature low, thereby increasing the energy efficiency of buildings and reducing energy consumption. Energy efficiency analyses conducted for Ankara, Antalya, Istanbul, Izmir, Kars, Kayseri, Konya, Mersin, and Tokat have revealed the potential for energy savings by using different absorption values (0.1, 0.4, 0.7) for exterior paint colors in these cities. These findings can be considered a crucial factor in the selection of colors for exterior paints to enhance the energy efficiency of buildings and to achieve sustainability goals in the respective regions.
Estimation of the abundance of the spinner dolphin Stenella longirostris using photo identification technique in Samadai Reef, Red Sea, Egypt

Dolphins were photographed for individual identification purposes in Samadai reef, Marsa Alam, Red Sea between January 2012 and March 2013. In this study, 255 spinner dolphin Stenella longirostris were identified with a mean identification rate of 45%. Photo-identification analysis provided a population size range of 567 to 637 for spinner dolphins utilizing Samadai daytime for resting and socializing. From the 255 identified dolphins, 33 individuals (12.9%) were re-sighted for 4-8 times and 131 individuals (51.4%) were only observed once. The discovery curve indicated the continuous entrance of new animals to Samadai reef, which increased between May and December.
Numerical study of the vortex generators effects in a corrugated channel for turbulent flow

Vortex Generators (VGs) are one of many techniques used to improve the efficiency of heat exchangers. In this paper, we will investigate in a numerical study a rectangular winglet and a long winglet VGs inside a corrugated channel with a change of Rynolds number from 5000 to 17500. The role of VGs is to manupilate flow, which increases the Nusselt number (Nu) and increases the friction coefficient, which are considered disadvantages. For that, we calculate the thermal performance coefficient PEC to see if VGs give us more heat compared to what we will lose from friction, and the results show a good PEC greater than 1, and comparing between rectangular and long VGs, we have almost the same results with a small difference in NU for rectangular VGs being higher than long VGs, and the coefficient of friction is smaller, which means we are battered. The results are discussed in detail in this paper.
Effect of changes in the net height, court size, and serve limitations on technical-tactical, physical, and psychological aspects of U-14 female volleyball matches

Introduction The objective was to analyze the effect of a reduction of the net height and the court size and serve limitations on the technical-tactical actions, physical actions, and psychological aspects in youth volleyball players. Methods The sample was 29 under-14 female volleyball players (three regional club teams). A quasi-experimental design was implemented to assess the effect of modification in three tournaments. The independent variables were: a) official rules tournament (no changes in the rules), b) Experimental Tournament 1 (reduction in the net height from 2.10 m to 2 m, no jump serves, and a maximum of two serves per player and rotation), and c) Experimental Tournament 2 (reduction in net height from 2.10 m to 2 m, reduction in court size from 9 × 9 m to 8 × 8 m, no jump serves, and a maximum of two serves per player and rotation). The dependent variables were: ball contact done (type), quality and efficacy of the technical actions, team game phases occurrence, quality and efficacy, continuity index, number of jumps, player's jump load in the take-off and landing, number of hits, average heart rate, Rate of Perceived Effort, time between ball contacts, serve velocity, perceived individual and collective self-efficacy, perceived enjoyment, and perceived satisfaction. Results Experimental Tournament 1 involved an increase in the efficacy of serves and a decrease in the efficacy of side-out phases. The imbalance between serve and reception did not impact game continuity but reduced the attack and blocks. Experimental Tournament 2 involved a decrease in the efficacy of serves and an increase in the efficacy of side-out phases. The balance between serve and reception increased reception efficacy, the occurrence of attacks and blocks, game continuity, and players' effort. players' effort. Discussion Scaling the net and court and adapting the serve rules (Experimental Tournament 2) resulted in game dynamics for these U-12 teams that were more similar to those of posterior stages of player through the balance between serve and reception and the adaptation of the net height and court size.
Analytic Geometry Problems Are Completed by Symbolic Visualization of Representation: A Case of a Future Teacher

One of the most important fundamental mathematical concepts for both students and teachers is mathematical representation. This study uses a qualitative method with a case study approach to examine aspiring teachers use visual and symbolic representations when addressing geometry problems. The participants in this study were 27 pre-service teachers from Indonesian Christian University (UKI) Toraja who were in their fourth semester. The processes of data reduction, data presentation, conclusion-making, and verification were applied to the data. The results of this study demonstrated that the pre-service teachers still lacked as they were provided inaccurate and non-detailed representations in symbolic imagery. Even though the responses are only half correct, the teachers with average academic competence have a semi-detailed symbolic visualization of capturing good visualization skills. Students with strong academic aptitudes have detailed representations in their symbolic representations, as well as great visual and symbolic representation skills. In order to assist students in teaching and studying geometry and resolve difficulties requiring mathematical expressions, pre-service teachers should have strong visual and symbolic representation skills.
