摘要: Photoplethysmogram (PPG) sensing is a field of signal measurement that involves accurate sensor design and efficient signal processing. Sensing interfaces have matured due to use of sophisticated nano-meter technologies, that allow for high speed, and low error sampling. Thus, in order to improve the efficiency of PPG sensing, the signal processing unit must be tweaked. A wide variety of algorithms have been proposed by researchers that use different classification models for signal conditioning关键词: Blood pressure;PPG;sensing;ensemble;classifier

摘要: In this work, the quantum computations of newly synthesized N-(4-hydroxyphenyl)picolinamide(4-HPP) is focused. Density functional theory (DFT) was used to perform the quantum calculations.The optimized molecular geometry was obtained using the B3LYP and MP2 methods employing6-311++G(d,p) basis set, which served as the foundation for all subsequent calculations. Theexperimental data was compared with the calculated vibrational frequencies and NMR spectra.

摘要: Oroantral fistula is a pathological and epithelised communication between pseudo stratified columnar ciliated epithelium of maxillary antrum and squamous epithelium of oral mucosa. Various techniques in literature point to the fact that repair of oroantral fistula is one of the most challenging problems in oral and maxillofacial surgery. Buccal advancement flap technique causes vestibular shortening, reduction in keratinized gingiva width with closure under tension thereby increasing the chances

摘要: Paranasal sinus (PNS) and nasal cavity tumors are rare, and account for 3% of all head and neck malignancies. Experience with endoscopic technique, advances in visualization, introduction of image guidance and development of surgical tools has led to a shift towards the treatment of PNS and nasal tumors through endoscopic approaches. Retrospectively study was done in a tertiary care institute from January 2008 to December 2018.

摘要: Foetal urinary tract dilation (UTD) abnormalities affect 1–5% of all pregnancies. However, exact incidence is difficult to estimate because of different terminologies used to define the condition and different grading systems to define its severity antenatally as well as postnatally worldwide. In order to overcome this problem, the new UTD classification system has been introduced in the year 2014 so as to have universal approach for diagnosis and management of UTD globally.

摘要: Image segmentation is a technique of subdividing an image into numerous sections that converts an image into more expressive form that is easier to analyze. Histogram is one of the most widely used techniques for segmenting a digital image due to its simplicity. However, this method often leads to unsatisfactory segmentation performance because of abnormalities on gray level histogram. In this paper, we propose a technique for segmenting a digital image through multilevel iterative variational m

摘要: An electromagnetic field radiations (EMF) emanating from the cell phones affect the brain and other organs in living organisms. Therefore, the objective of the present study is to examine whether the EMF radiations affect the brain cells or not, using the transfer learning-based methodology. The observations made in the present study are based on our experiment with the Drosophila melanogaster. The microscopic brain-images of drosophila, (should be read as micro-images) exposed to and not expose

摘要: We developed a gonad cell line, CMgT-1, from the testes of Clarias magur in L-15 media with 20% FBS at 28 °C temperature and sub-cultured it more than 50 times. The origin of the cell line was validated using two universal markers, viz. cytochrome oxidase c subunit I and 16S rRNA genes. Cytogenetic analysis of the cells at 32nd passage revealed diploid chromosome number of 50. Immuno-phenotyping assay confirmed an epithelial-like cell type. The cell line was tested for mycoplasma contamination a

摘要: BACKGROUND(#br) A major concern and challenge faced by the educational institution during coronavirus disease (COVID-19) pandemic and consequent lockdown is the timely conduct of the summative assessment. Unlike cognitive assessment, real-time practical assessment through online mode, without compromising principles of assessment is difficult. This study was performed to analyze an alternative hybrid approach adopted for the postgraduate practical summative assessment in pathology.

摘要: Schizothorax richardsonii, commonly called snow trout is a vulnerable coldwater fish distributed in India and adjoining countries, is an important resource as food, ornamental and game fishery. A cell line, designated as SREM-1, has been established from the eye muscle of S. richardsonii using explant method and cultured in Leibovitz`s L-15 medium. The growth studies at 20-32°C temperatures and 5-20% of fetal bovine serum (FBS) concentrations revealed that SREM-1 cells exhibited optimal growth a关键词: Cell line; Cytotoxicity; India; Mercury chloride; NRFC; Schizothorax richardsonii

摘要: Endogenous iron quickly interchanges its oxidation states (Fe III and Fe II), which modulate production of reactive oxygen species (ROS) and nitric oxide (NO), and also serve as co-factor for various enzymes. A sharp increase in Fe(III) content in mature fruits of tomato (climacteric) is a unique observation from the present work. Iron homeostasis in non-climacteric capsicum fruits, however, accompanies a balancing of Fe(III) and Fe(II) levels during turning and ripe stages. Heme oxygenase-1 (HO

摘要: Digital image watermarking serves as a tool for protection of ownership of the media shared on common platform. This paper presents a robust, blind watermarking technique for colour images based on singular value decomposition (SVD) and discrete wavelet transform (DWT). Watermark is embedded in mid-frequency sub-bands of two-level DWT. These sub-bands are divided into non-overlapping blocks of size 4 × 4, each of which undergoes SVD. The singular values (SV) are updated based on watermark bit a关键词: image watermarking;image processing;singular value decomposition;SVD;discrete wavelet transform;DWT

摘要: Summary(#br)Mitogen-activated protein kinases (MAPKs) control essential eukaryotic signaling pathways. While much has been learned about MAPK activation, much less is known about substrate recruitment and specificity. MAPK substrates may be other kinases that are crucial to promote a further diversification of the signaling outcomes. Here, we used a variety of molecular and cellular tools to investigate the recruitment of two substrate kinases, RSK1 and MK2, to three MAPKs (ERK2, p38α, and ERK5)关键词: ERK2; MAP kinase; MK2; NMR; RSK1; SAXS; X-ray crystallography; Cellular signaling; P38; Protein kinase complex

摘要: Li-Fraumeni syndrome (LFS) is a highly penetrant autosomal dominant cancer predisposition disorder caused by germline TP53 pathogenic variants. Patients with LFS have increased oxidative phosphorylation capacity in skeletal muscle and oxidative stress in blood. Metformin inhibits oxidative phosphorylation, reducing available energy for cancer cell proliferation and decreasing production of reactive oxygen species that cause DNA damage. Thus, metformin may provide pharmacologic risk reduction for

Although many studies have addressed the issue, our objective was to perform a meta-analysis to bring a consensus on the perioperative risk factors promoting AKI postoperatively. We conducted a systematic review and meta-analysis of observational studies reporting risk factors with odds of development of

摘要: Abstract(#br)Digital Image Watermarking using Singular Value Decomposition has a fundamental flaw of false watermark generation when Singular Values of the watermark are embedded into the cover. The proposed work embeds Principal Components of two watermarks instead, to overcome this flaw. These watermarks are embedded into horizontal and vertical sub-band coefficients of 3-level DWT of the cover respectively. Keys based on cover and watermarks are generated and used for cover and watermark veri关键词: Digital image watermarking; False watermark generation; False cover claim; Image processing attacks; Image security; Singular value decomposition

摘要: Abstract(#br)In this paper, a new well-organized fusion-based 3D Otsu energy thresholding prototypical for multilevel color image segmentation by means of lightning search algorithm (LSA) has been projected. Although, 3D Otsu works by means of between-class variances over the help of 3-D histogram but the performance is not satisfactory. As a result, the energy curve model is implemented, that works on contextual information of an image. However, using the concept of energy curve for 3D Otsu pro关键词: Context; Multi-level segmentation; 1D; 2D; And 3D otsu; Image fusion; Local contrast; And image thresholding
