Real-Time Tracking Algorithm for Aerial Vehicles Using Improved Convolutional Neural Network and Transfer Learning

To address the poor image feature extraction ability, excessive tracking time, and low accuracy of traditional real-time algorithms for aerial tracking of vehicle traffic, a real-time tracking algorithm using improved convolutional neural network (CNN) and transfer learning was proposed herein. In this algorithm, first, the aerial vehicle images are matched with sample images for the image offset calibration. Second, the CNN parameters are initialized by constructing a filter set, and transfer learning is employed to construct a CNN pre-training model. Third, a deep convolution feature extraction structure map is designed to extract the depth features of images. Finally, based on the depth features, the target vehicle motion model is established, the similarity between the target and candidate models is calculated, and the real-time tracking of aerial vehicles is completed. The results show that the image correction accuracy of the proposed algorithm is as high as 92%. The algorithm yields satisfactory results in terms of feature extraction and calculation accuracy. Moreover, it has a small overall error, the average tracking time required by it is only 22.8 s, and its false negative rate is as low as 0.4%. Therefore, the proposed algorithm has considerable potential practical application.
Analysis of simple sequence repeats in Period genes in mammals

Circadian rhythm is driven by the circadian clock. One of the core clock genes identified is Period (Per) in Drosophila and Period1 (Per1), Period2 (Per2), and Period3 (Per3) in mammals. The present study examines the presence of perfect simple sequence repeats (SSRs) in human Period genes and their orthologues in chimpanzee, gorilla, orangutan, gibbon, and mouse. Comparisons of all Per genes show a higher density of SSRs in Per1 of all organisms followed by Per3 and Per2 with exceptions. Possibly due to higher chances of mutations, CG-rich repeats are not abundant in Per genes. This analysis shows gene and species-specific distribution of repeats along with region-specific distribution of repeat types and repeat motifs in exons and introns of the Per genes. There is diverse distribution of CG-rich repeat types and motifs in the three Per and also in exons and introns of the three genes in different organisms. Long perfect SSRs are generally not common. Since perfect SSRs are prone to mutations, there is a need to study SSRs, especially found in exons of human Per genes which could serve as markers for investigators to study the role of such SSRs in Per-related disorders.

Bioprospecting of endophytic bacteria from the Indian Himalayas and their role in plant growth promotion of maize (Zea mays L.)

Endophytes are the hidden companions of inner plant tissues with the ability to undergo various plant growth mechanisms to benefit their host. Looking at the endophytic microbes’ benefits, a total of 67 putative endophytic bacteria were isolated using different nutrient growth media from three diverse maize genotypes grown at Baru Sahib the “Valley of Divine Peace” Himachal Pradesh. Out of the 67, 10 endophytic bacterial isolates were selected for further characterization on the basis of plant growth-promoting (PGP) attributes. Phosphorus (P) and potassium (K) solubilization was observed in about 25% of the bacterial isolates. Additionally, bacterial endophytes’ ability to undergo mechanisms like nitrogenase activity, production of indole acetic acids, and siderophores was also studied. Among the 10 selected bacterial strains, three efficient endophytic PGP strains EU-A2SK1, EU-M4ARAct, and EU-E1RT3-1 were identified as Pseudomonas brenneri, Ewingella americana, and Pantoea agglomerans, respectively. The phylogenetic tree was constructed to know the taxonomical affiliations of selected bacterial strains. These three efficient endophytic bacterial strains were tested on the maize seeds. The isolates efficiently increased the shoot length and enhanced anthocyanin, chlorophyll content, physiological available iron, and total protein content when compared to untreated control maize plants at 60 days of maize plant growth. These bacterial strains, as single or in a consortium, could be useful as bioinoculants for sustainable agriculture.
Study of Silicon Dioxide Nanowires Grown via Rapid Thermal Annealing of Sputtered Amorphous Carbon Films Doped with Si

Silica nanowires are usually synthesized by means of vapor liquid solid method with metal catalyst introduced at the top which will unambiguously affect the excellent light emission properties of silica nanowires in optoelectronic devices an optical sign l sensors. In this study, silicon dioxide nanowires without traces of catal st are grown via rapid thermal annealing of magnetron sputtered amorphous carbon film doped with silicon. These high density silicon dioxide nanowires were amorphous with a length longer than 20 m and a diameter of 30–140 nm. Detailed morphology and microstructure analysis are conducted with field emission scanning electron microscopy and high resolution transmission electron microscopy. Graphitization of carbon and oxidation of silicon during rapid thermal annealing were revealed by Raman and X-ray photoelectron spectroscopy. This study indicates that high growth rate of >6 m/min of high purity silicon dioxide nanowire is possible simply by sputtering followed by rapid thermal annealing and an additional heating treatment.
Uncertainty estimation for deep learning-based automated analysis of 12-lead electrocardiograms

Abstract Aims Automated interpretation of electrocardiograms (ECGs) using deep neural networks (DNNs) has gained much attention recently. While the initial results have been encouraging, limited attention has been paid to whether such results can be trusted, which is paramount for their clinical implementation. This study aims to systematically investigate uncertainty estimation techniques for automated classification of ECGs using DNNs and to gain insight into its utility through a clinical simulation. Methods and results On a total of 526 656 ECGs from three different datasets, six different methods for estimation of aleatoric and epistemic uncertainty were systematically investigated. The methods were evaluated based on ranking, calibration, and robustness against out-of-distribution data. Furthermore, a clinical simulation was performed where increasing uncertainty thresholds were applied to achieve a clinically acceptable performance. Finally, the correspondence between the uncertainty of ECGs and the lack of interpretational agreement between cardiologists was estimated. Results demonstrated the largest benefit when modelling both epistemic and aleatoric uncertainty. Notably, the combination of variational inference with Bayesian decomposition and ensemble with auxiliary output outperformed the other methods. The clinical simulation showed that the accuracy of the algorithm increased as uncertain predictions were referred to the physician. Moreover, high uncertainty in DNN-based ECG classification strongly corresponded with a lower diagnostic agreement in cardiologist’s interpretation (P < 0.001). Conclusion Uncertainty estimation is warranted in automated DNN-based ECG classification and its accurate estimation enables intermediate quality control in the clinical implementation of deep learning. This is an important step towards the clinical applicability of automated ECG diagnosis using DNNs.
IVUS-Guided Zero-Contrast PCI in CKD Patients: Safety and Short-Term Outcome in Patients with Complex Demographics and/or Lesion Characteristics

Background. Percutaneous coronary intervention (PCI) in patients with significant renal dysfunction is challenging because of the lesion characteristics and the risk of contrast-induced acute kidney injury (CI-AKI). With the advent of intravascular ultrasound- (IVUS-) guided zero-contrast PCI, outcomes have improved considerably. Objective. To assess the safety and short-term outcomes of IVUS-guided zero-contrast PCI in chronic kidney disease (CKD) patients with complex demographics or lesion morphology. Methods. Patients who underwent IVUS-guided zero-contrast PCI at a tertiary center, from November 2019 to May 2020, were included in this prospective analysis. Clinical characteristics, procedural data, and follow-up data were collected and analyzed. Results. A total of 15 patients (27 vessels), all men (mean age, 70.0 ± 11.0 years), underwent zero-contrast PCI. The mean estimated glomerular filtration rate (eGFR) and serum creatinine were 30.8 ± 7.3 mL/min/1.73 m2 and 2.6 ± 1.3 mg/dL, respectively. The mean BMC2 risk for dialysis was 2.1 ± 1.1%, mean SYNTAX score was 20.3 ± 10.3, and mean left ventricular ejection fraction (LVEF) was 42.4 ± 11.6%. Four patients (26.6%) underwent left main coronary artery (LMCA) PCI including one LMCA bifurcation. One patient underwent chronic total occlusion PCI. Technical and procedural success were 100% without any periprocedural complications. No major adverse cardiovascular events (MACE) were reported, and no patient required dialysis within three months of follow-up. Conclusion. Zero-contrast PCI guided by IVUS is safe in coronary artery disease (CAD) patients with moderate-to-severe CKD. High procedural success without complications can be achieved even in cases with complex clinical characteristics and lesion morphology.

Synergism of Temozolomide, Metformin and Epigallocatechin Gallate Promotes Oxidative Stress-induced Apoptosis in Glioma Cells

To study the synergistic anti-glioma efficacies of Temozolomide, Metformin and Epigallocatechin Gallate in U87MG and C6 glioma cells. Glioblastoma (GBM) is the most malignant and invasive tumor of the central nervous system. The current standard treatment comprises surgical resection, followed by adjuvant radiotherapy and chemotherapy employing temozolomide (TMZ). Yet the survival rates for GBM patients is very low. Hence there is a need for new treatment regimes This study was aimed to unravel the synergistic anti-tumor potential of a biguanide drug, Metformin (MET) and a polyphenol, Epigallocatechin gallate (EGCG) to enhance the anti-GBM efficacy of the standard drug. Anti-proliferative effect of TMZ, MET and EGCG, individually and in combination was elucidated in U87MG (human) and C6 (rat) glioma cells using MTT assay and combination index was used to determine synergism. Cytotoxicity of the drugs was performed in HEK293T noncancerous cells. Apoptotic morphological changes in the cells were observed by AO/EtBr staining. Further, the effect of drugs on antioxidant and apoptotic genes (SOD, CAT, Nrf-2, Caspase-9 and Bcl-2) were evaluated using qRT-PCR and the protein levels of Nrf-2 and Caspase-9 was evaluated using ELISA. The triple-drug combination (TMZ+ MET+ EGCG) synergistically inhibited the proliferation of U87MG and C6 glioma cells in a dose-dependent manner and promoted the apoptosis of glioma cells. The triple-drug combination significantly up-regulated the expression of antioxidant and apoptotic genes and induced oxidative stress suggesting a shift in equilibrium towards apoptosis. MET and EGCG in combination with TMZ synergistically promoted oxidative stress induced apoptosis in glioma cells. Hence, the combination of TMZ, MET and EGCG may be therapeutically exploited for improving the clinical outcomes of patients with GBM.
Twisted BRST symmetry in gauge theories on the 
κ
-Minkowski spacetime

Algebraic properties of the Becchi-Rouet-Stora-Tyutin (BRST) symmetry associated to the twisted gauge symmetry occurring in the $\ensuremath{\kappa}$-Poincar\'e invariant gauge theories on the $\ensuremath{\kappa}$-Minkowski space are investigated. We find that the BRST operation associated to the gauge invariance of the action functional can be continuously deformed together with its corresponding Leibniz rule, into a nilpotent twisted BRST operation, leading to a twisted BRST symmetry algebra which may be viewed as a noncommutative analog of the usual Yang-Mills BRST algebra.
Implementing continuous consent in qualitative research

This article examines ways of approaching informed consent as a relationally constituted process in qualitative research practices. It argues that a researcher’s operationalization of informed consent should be coherent with the overall epistemological framework of the project. Based on empirical examples from an ethnographic inquiry in an educational setting, the principle of informed consent is discussed as a reflexive and ethical tool throughout the inquiry, including its pre-fieldwork, fieldwork and post-fieldwork phases. Strategies of explicitly and implicitly (re)negotiated consent and dissent are discussed and illustrated by drawing on some of the recent discussions of continuous consent practices. The article’s conceptualization of a continuous, situated and relational approach to informed consent is also supported by the concepts of response-ability and thinking with care in research ethics.
A Comparative Kinetic Study of Chalcopyrite Leaching Using Alternative Oxidants in Methanesulfonic Acid System

ABSTRACT Methanesulfonic acid was proven to be an alternative lixiviant for copper leaching from chalcopyrite with hydrogen peroxide as an oxidant. Two alternative oxidants, dichromate and nitrate, were studied for the copper dissolution from chalcopyrite, a refractory copper sulfide mineral. During chalcopyrite leaching tests, both oxidants achieved the copper extraction above 90% in 30 g/L methanesulfonic acid at 75oC. The activation energies in dichromate and nitrate leaching systems were 23 and 43 kJ/mol, classified as mass transfer and chemical reaction-controlled mechanism, respectively. The XRD analysis of a leached residue showed a formation of K-Cr-jarosite from methanesulfonic acid-dichromate system. Methanesulfonic acid with nitrate leaching system could be the most effective and sustainable for chalcopyrite leaching based on the comparative investigation.
An Overview on Omnichannel Inventory Strategy under Uncertain Demand

With the improvement of people’s living standards, there are higher requirements for product quality and personalization. At the same time, the development of science and technology, such as big data, cloud computing, VR, etc., provides technical support to meet the higher shopping needs of consumers. Promoted by these two factors, omnichannel came into being. In the omnichannel model, a single demand may exist in multiple channels, which increases the difficulty of retailer demand forecasting and brings challenges to the inventory management of omnichannel retailers. This article sorts out and analyzes the changes in omnichannel consumer demand, the relationship between channels, and the related research on multi-channel and omnichannel inventory strategies, and finds that there are few studies on omnichannel inventory strategies. At present, the research on omnichannel inventory strategy is mostly based on a specific omnichannel model inventory strategy research. The characteristics of omnichannel such as changes in demand and channel relationship have not been included in the relevant research. The characteristics of omnichannel such as changes in demand and channel relationship have not been included in the relevant research. This paper proposes that future research can pay more attention to the impact of the new characteristics of the omnichannel model on inventory management, as well as the challenges of inventory management caused by the competition and cooperation between channels, and provide a scientific basis for omnichannel inventory management.
In Situ Cattle Rumen Degradability of Urea-Molasses and Cellulase Treated Rice Straw

In situ(nylon bag) technique was used to investigate the effects of BIOTECH -Cellulase fromTrichoderma reeseiRUT -C40 on rumen degradability of rice straw in the study. Three mature rumen cannulated steerswere used. Complete Randomized Design (CRD) was used to evaluate the effect of four treatments in steers. Dietary treatments were used in the study as; Untreated rice straw (UTRS); Urea and mola sses treated rice straw (5% urea + 5% molasses) (UMTRS); Urea, molasses and cellulase treated rice straw 5% urea + 5% molasses + 2.5% BIOTECH -Cellulase fromTrichoderma reeseiRUT -C40 (UMCTRS) and 2.5% BIOTECH -Cellulase treated rice straw (CTRS). All treatments had similar (P>0.05) degradation of DM and NDF of untreated and treated rice straw . The increasing degradability of the rice straw treated with BIOTECH -Cellulase as observed in both the UM CTRS and CTRS, incubated for 72h suggested that the enzyme can still improve the utilization of the feed such that longer in cubation would degrade rice straw significantly

Synthesis of new, single-isomer quaternary ammonium derivatives of beta-cyclodextrin for electrophoretic enantiomer separations

Synthesis of New, Single-Isomer Quaternary Ammonium Derivatives of β-Cyclodextrin for Electrophoretic Enantiomer Separations. (May 2006) Kingsley C. I. Nzeadibe, B.S., University of Oklahoma; M.S., Louisiana Tech University Chair of Adversory Committee: Dr. Gyula Vigh The isolation of individual enantiomers of drugs is an important subject of interest in the pharmaceutical and medical fields, because stereochemistry can have a significant effect on the biological activity of the drug. Therefore, it is important to develop enantiomeric separation methods for the determination of the optical purity of drugs, since the undesired enantiomer is regarded as one of the impurities. The available single isomer anionic cyclodextrins (CD) can resolve the enantiomers of only a few weakly acidic analytes. To rectify this problem, the chloride salts of heptakis(6-deoxy-6-morpholinio)-cyclomaltoheptaose (HMBCD), and mono(6deoxy-6-N,N,Nr,Nr,Nr-pentamethylethylenediammonio)-cyclomaltoheptaose (PEMEDA-BCD), the first members of the permanently charged, single-isomer cationic cyclodextrin family, have been synthesized. The purity of process intermediates and final products was determined by HPLC-ELSD and indirect UV-detection capillary electrophoresis. Structural identity was verified by 1D and 2D NMR and mass spectrometry.
Pneumatic Artificial Muscle Based on Novel Winding Method

This paper proposes a pneumatic artificial muscle based on a novel winding method. By this method, the inflation of silicone tubes is transformed to the contraction of muscle, whereas the expansion keeps on one side of the muscle, i.e., the expansion of the actuator does not affect the object close to it. Hence the muscle is great for wearable robots without squeezing on the user’s skin. Through necessary simplification, the contraction ratio model and force model are proposed and verified by experiments. The prototype of this paper has a maximum contraction ratio of 35.8% and a maximum output force of 12.24 N with only 5 mm thickness. The high compatibility proves it excellent to be the alternative for wearable robots.
