PAOD: a predictive approach for optimization of design in FinFET/SRAM

The evolutions in the modern memory units are comeup with FinFET/SRAM which can be utilized over high scaled computing units and in other devices. Some of the recent systems were surveyed through which it is known that existing systems lags with improving the performance and optimization of FinFET/SRAM design. Thus, the paper introduces an optimized model based on Search Optimization mechanism that uses Predictive Approach to optimize the design structure of FinFET/SRAM (PAOD). Using this can achieve significant fault tolerance under dynamic cumpting devices and applications. The model uses mathematical methodology which helps to attain less computational time and significant output even at more simulation iteration. This POAD is cost effective as it provides better convergence of FinFET/SRAM design than recursive design

A novel optimization framework for controlling stabilization issue in design principle of FinFET based SRAM

The conventional design principle of the finFET offers various constraints that act as an impediment towards improving ther performance of finFET SRAM. After reviewing existing approaches, it has been found that there are not enough work found to be emphasizing on cost-effective optimization by addressing the stability problems in finFET design.Therefore, the proposed system introduces a novel optimization mechanism considering some essential design attributes e.g. area, thickness of fin, and number of components. The contribution of the proposed technique is to determine the better form of thickness of fin and its related aspect that can act as a solution to minimize various other asscoiated problems in finFET SRAM. Implemented using soft-computational approach, the proposed system exhibits that it offers better energy retention, lower delay, and potential capability to offer higher throughput irrespective of presence of uncertain amount of noise within the component

Non-ossifying fibroma of distal tibia: case report

Non-ossifying fibroma is a benign fibrohistiocytic lesion most commonly seen in the metaphyseal region in children. It usually doesn’t present with any symptoms. As the bone grows and undergoes remodeling, the lesion tends to vanish and get substituted with healthy bone. Nonetheless, the lesion can debilitate the affected bone, leading to a potential fracture. Here, we report a case of non-ossifying fibroma in the metaphyseal region of the tibia in a 13-year female. The patient presented with complaints of pain in the left leg for 5 months and underwent radiological investigation showing a well-defined, multi-loculated, expansile, radiolucent, lytic lesion with a thin sclerotic margin in the meta-diaphyseal region of the distal tibia, for which extended bone curettage with bone grafting was performed. The sample was sent for histopathological examination, which showed bony trabeculae with bits of tumor composed of spindle cells with elongated nuclei and scant cytoplasm, arranged in a storiform pattern along with many scattered multinucleate giant cells and foamy histiocytes suggestive of non-ossifying fibroma. Post operatively, non-weight bearing mobilization was advised for 4 weeks. Most non-ossifying fibromas were diagnosed in childhood to late adolescence, found incidentally, and clinically asymptomatic. Most distal tibial non-ossifying fibromas (NOFs) tend to transpire at a specific anatomical site located at the far end of the interosseous membrane. The prognosis for NOFs is typically excellent with a low risk of recurrence

Supracondylar humerus fracture in children: K wire pinning with minimal sterile technique

A minimal sterile technique to assess the outcome of K wire pinning of Supracondylar fracture of humerus in children. A prospective case series between 2018 to 2020 was conducted on 10 supracondylar fracture of humerus operated at a tertiary care centre. Gartland type 2 and 3 were included and all the patients were treated with minimal sterile K-wire pinning technique. After 18 weeks follow up with mean age of 7.3 years, all patients were found to have excellent results. In our study no patients received antibiotic except in one patient where 5 days of oral antibiotic cefixime was given. Less complications, reduced time of surgery of average 24.3 minutes, reduction in cost factor and patient compliance was better. Supracondylar fracture of humerus can be fixed by K-wire fixation with minimal sterile technique either by cross pinning or lateral pinning which has same outcome as sterile technique and minimal sterile technique is cost effective and time sparing

ANTIBACTERIAL AND ANTIOXIDANT ACTIVITIES OF STEM BARK ESSENTIAL OIL CONSTITUENTS OF LITSEA GLUTINOSA C. B. ROB.

Objective: To evaluate the chemical composition, antibacterial and antioxidant properties of stem bark essential oil of Litsea glutinosa C. B. Rob.Methods: The essential oil isolated from stem bark of L. glutinosa and their chemical composition was analyzed by gas chromatography coupled with mass spectrometry detector. The in vitro antibacterial activity of the stem bark essential oil was investigated against eight human pathogenic bacterial clinical isolates using agar disc diffusion method and MIC value was determined by modified resazurin microtitre-plate assay. The antioxidant activity of essential oil was measured by 2, 2-diphenyl-1-picrylhydrazyl radical (DPPH), 2, 2-azinobis-3-ethylbenzothiazoline-6-sulphonate radical cation (ABTS) and β-carotene bleaching assay.Results: GC-MS analysis of stem bark essential oil resulted in the identification of 37 compounds, off which 9,12-octadecadienoic acid (62.57%), hexadecanoic acid (12.68%), stigmast-5-en-3-ol (6.87%) and vitamin E (2.51%) were the main constituents representing 84.63% of the oil. The determination of in vitro antibacterial activity of stem bark essential oil resulted in significant inhibition zone (15.00±0.57 mm) and MIC value (0.15±0.15×10-2 mg/ml) against the pathogenic bacteria Vibrio cholera followed by Pseudomonas aeruginosa and Salmonella typhi. The results of DPPH radical scavenging (IC50:4.540±0.06 µg/ml), ABTS (IC50:256.02±0.06 µg/ml) and β-carotene bleaching assay (%I: 78.51±0.42 %) showed significant in vitro antioxidant property.Conclusion: L. glutinosa stem bark essential oil showed potential antibacterial activity against the Vibrio cholera. The results of this investigation supported the ethnomedical claim of essential oil as a demulcent, antidiarrheal and antioxidant drug

Chandra High Resolution X-ray Spectroscopy of AM Her

We present the results of high resolution spectroscopy of the prototype polar AM Herculis observed with Chandra High Energy Transmission Grating. The X-ray spectrum contains hydrogen-like and helium-like lines of Fe, S, Si, Mg, Ne and O with several Fe L-shell emission lines. The forbidden lines in the spectrum are generally weak whereas the hydrogen-like lines are stronger suggesting that emission from a multi-temperature, collisionally ionized plasma dominates. The helium-like line flux ratios yield a plasma temperature of 2 MK and a plasma density 1 - 9 x10^12 cm^-3, whereas the line flux ratio of Fe XXVI to Fe XXV gives an ionization temperature of 12.4 +1.1 -1.4 keV. We present the differential emission measure distribution of AM Her whose shape is consistent with the volume emission measure obtained by multi-temperature APEC model. The multi-temperature plasma model fit to the average X-ray spectrum indicates the mass of the white dwarf to be ~1.15 M_sun. From phase resolved spectroscopy, we find the line centers of Mg XII, S XVI, resonance line of Fe XXV, and Fe XXVI emission modulated by a few hundred to 1000 km/s from the theoretically expected values indicating bulk motion of ionized matter in the accretion column of AM Her. The observed velocities of Fe XXVI ions are close to the expected shock velocity for a 0.6 M_sun white dwarf. The observed velocity modulation is consistent with that expected from a single pole accreting binary system.Comment: 6 figures, AASTEX style, accepted for publication in Ap

INTERNET OF THINGS BASED SMART HELMET FOR ALERTING ACCIDENT

Abstract This article is about a smart helmet, a novel idea that increases the safety of motorcycle riding. In order to stop vehicles from starting while the driver is not wearing a helmet, this technique was developed. or is inebriated. Furthermore, with the help of a GPS GSM-based tracking system, it detects accidents and sends SMS notifications to particular persons showing the bike's location and speed just before the collision, assisting ambulances in arriving at the precise spot. We want to integrate all of the sensors into the helmet, which will wirelessly transmit data to the module attached to the bike engine. There will be two modules in this smart motorcycle helmet system with one helmet and one motorcycle. The bike module has a vibration sensor, GPS, and GSM, whilst the helmet module has an alcohol sensor, a helmet sensor, and a switch. Both of these modules connect wirelessly using an Arduino as a microcontroller and an RF transmitter and receiver with encoder and decoder

U(1) Gauge Theory as Quantum Hydrodynamics

It is shown that gauge theories are most naturally studied via a polar decomposition of the field variable. Gauge transformations may be viewed as those that leave the density invariant but change the phase variable by additive amounts. The path integral approach is used to compute the partition function. When gauge fields are included, the constraint brought about by gauge invariance simply means an appropriate linear combination of the gradients of the phase variable and the gauge field is invariant. No gauge fixing is needed in this approach that is closest to the spirit of the gauge principle. We derive an exact formula for the condensate fraction and in case it is zero, an exact formula for the anomalous exponent. We also derive a formula for the vortex strength which involves computing radiation corrections.Comment: 15 pages, Plain LaTeX, final published versio

Single-Particle Green Functions in Exactly Solvable Models of Bose and Fermi Liquids

Based on a class of exactly solvable models of interacting bose and fermi liquids, we compute the single-particle propagators of these systems exactly for all wavelengths and energies and in any number of spatial dimensions. The field operators are expressed in terms of bose fields that correspond to displacements of the condensate in the bose case and displacements of the fermi sea in the fermi case. Unlike some of the previous attempts, the present attempt reduces the answer for the spectral function in any dimension in both fermi and bose systems to quadratures. It is shown that when only the lowest order sea-displacement terms are included, the random phase approximation in its many guises is recovered in the fermi case, and Bogoliubov's theory in the bose case. The momentum distribution is evaluated using two different approaches, exact diagonalisation and the equation of motion approach. The novelty being of course, the exact computation of single-particle properties including short wavelength behaviour.Comment: Latest version to be published in Phys. Rev.
