Artificial Intelligence (AI) has revolutionized numerous industries by enabling machines to simulate human intelligence and perform tasks that were once exclusive to humans. However, there is a rising star in the field of technology known as cognitive technology, which holds the potential to surpass the limitations of traditional AI systems. Cognit...

An individual of Varanus flavescens Hardwicke and Gray, 1827 has been recorded from the Laksar-Aithal road, near Bukkanpur village in Haridwar district of the Uttarakhand State. The area lies under the khadar plains and consists of numerous perennial and annual water streams, which all are the tributaries to river Ganges. Considering the reliable r...

In this study, the influence of hybrid nanocutting fluid (both graphite and talc nanoparticles dispersed in a base fluid) in turning of Titanium alloy grade 5. The hybrid nanocutting fluid was developed by the blending of graphite and talc nanoparticles in a constant volumetric proportion (50:50) in pure coconut oil as a base fluid. The prepared hy...

A case-control study was done to decipher whether the FRAX tool was useful in India. Several values around the mean and median of the FRAX score of the case group were assessed to calculate sensitivity, specificity, positive predictive value, negative predictive value, Youden’s index and odds ratio, and to detect high-risk individuals.PurposeThe Fr...

Brakes are very important component in any vehicle, used to stop the motion of it either by applying mechanical or hydraulic pressure on brake pads. By engaging and disengaging of braking action, the surface of brake components (or) materials is ruined after some time. Therefore, it is important to study and develop a new composition of brake mater...

Background: The rising trend of antibiotic resistance imposes a heavy burden on healthcare both clinically and economically (US$55 billion), with 23,000 estimated annual deaths in the United States as well as increased length of stay and morbidity. Machine-learning–based methods have, of late, been used for leveraging patient’s clinical history and...

Waste dumping sites near protected areas are a growing issue, which may affect the activities and behaviour of wildlife, more than what we notice. Here, we present two of our case studies, where Asian Elephants were found feeding at garbage dumps in Haridwar and Ramnagar forest divisions in the Shivalik Elephant Reserve in Uttarakhand State. Since...

This short note reports about the occurrence of Fowlea sanctijohannis Boulenger, 1890 in the State of Uttarakhand, North India. Species has been recorded from the Lansdowne Forest Division, which falls under the tropical dry deciduous forest type. Based on the morphological characters and quite a few available records; ecological data and taxonomic...

Objective: Osteoporosis causes fragility fractures that also occur in patients with bone mineral density (BMD) in the normal or osteopenic range, suggesting role of risk factors that are unrelated or partially related to BMD. The study aims at highlighting the link between 3 conditions, that are environment and occupation related risk factors and t...

The presence of harmonics in locomotives used in Indian Railways has started to become one of the major concerns during the last few years. The cause of harmonics distortions in these locomotives is due to the increase in the use of power electronics devices, wherein the introduction of GTO and IGBT-based locomotives have brought up technological a...

Rising antibiotic resistance inflicts a heavy burden on healthcare, both clinically and economically. Owing to the time required to obtain culture and sensitivity test results, quite often the clinicians rely on their experience and static clinical guidelines to prescribe antibiotics. Such empirical treatment often fails to account for patient-spec...

Background: Emergency abdominal condition had good prognosis if they diagnosed early and had better prognosis. Many biological parameters were considered to reduce postoperative complications. This study aims to study the effects of CRP and 24-hour lactate clearance on morbidity and mortality of patients undergoing emergency abdominal surgery.Metho...

BRCA2 is essential for maintaining genomic integrity. BRCA2-deficient primary cells are either not viable or exhibit severe proliferation defects. Yet, BRCA2 deficiency contributes to tumorigenesis. It is believed that mutations in genes such as TRP53 allow BRCA2 heterozygous cells to overcome growth arrest when they undergo loss of heterozygosity....

Background To study CT and MR findings in xanthogranulomatous cholecystitis (XGC). Material/Methods Retrospective analysis of 30 histopathologically confirmed cases of XGC. Seventeen patients underwent CECT and 13 underwent MRI. The following features were studied – wall thickness, intramural nodules, pericholecystic stranding, wall thickness, THA...

Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal blee...

We present an extremely rare case of caudate lobe intrahepatic pancreatic pseudocyst with spontaneous rupture into the inferior vena cava (IVC). A 58-year-old male, a chronic alcoholic, presented with features of pancreatitis for which imaging was done. Ultrasound and contrast-enhanced computed tomography were carried out, which revealed intrahepat...

Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis characterized by xanthogranulomatous inflammation of the gallbladder. Intramural accumulation of lipid-laden macrophages and acute and chronic inflammatory cells is the hallmark of the disease. The xanthogranulomatous inflammation of the gallbladder can be very...

To cope with the current momentous demanding scenario for the food as well as nutritional security, vegetable has got an upper hand by countering hidden hunger and malnutrition especially in developing countries like India. Recently, the production of vegetables got significant improvement over the past both quantity as well as quality wise thanks...

We consider the problem of delay minimization over the downlink of a heterogeneous wireless network (HetNet) by optimizing the association of users to transmission points (TPs) subject to per-user maximum rate constraints. The user association problem is formulated as a constrained set function minimization problem and our key result is to show tha...

A low noise-figure (NF) and Unity power gain 1–100 GHz ultra-wideband Low Noise π Network with excellent linearity is reported. An π-match input network, Capacitive feedback with series and shunt inductive peaking techniques are used to achieve wideband impedance matching with low noise figure as well as flat unity gain response. This technique exi...

Ultra wide band Low Noise Darlington Amplifier for High Frequency application is presented. Based on the MOSFET Switching with inductive feedback techniques and inductive peaking method, this technique exits many resonators with high quality factor at different resonance frequencies, Voltage series feedback consist using feedback element inductor,...

We consider the problem of maximizing the alpha-fairness utility over the downlink of a heterogeneous wireless network (HetNet) by jointly optimizing the association of users to transmission points (TPs) and the activation fractions of all TPs. Activation fraction of each TP is the fraction of the frame duration for which it is active, and together...

Efficient uplink scheduling in Ethernet passive optical networks (EPONs) is very important for maximizing the network capacity while maintaining the required quality of service (QoS). Several variants of dynamic bandwidth resource allocation have been proposed in recent research literature. However, the available techniques do not fully exploit the...

We propose a new channel rate and queue state adaptive time resource allocation heuristic for the base stations in a multiuser wireless access scenario. Motivation of the scheme is derived through the effective capacity concept. Our proposed strategy accounts for fairness and quality-of-service (QoS) of the system on per frame basis. Our results sh...
