The International Conference on Recent Trends in Physics (ICRTP2012) took place Indore, India, 4?5 February 2012. conference was hosted by the School of Physics, Devi Ahilya University, Indore ? 452001. objective to provide a platform for interaction among scientists, teachers, researchers and students, share their ideas, thoughts scientific findings various areas physics. ICRTP2012 attracted total 130 abstracts submitted scientists from 7 different countries. included an inaugural talk 13...
Abstract We present a broadband X-ray study (∼0.3–50 keV) of the dwarf nova SS Cyg highlighting changes in accretion during two phases, quiescence and outburst states. The investigation was based on simultaneous observations carried out with XMM-Newton NuSTAR telescopes epochs, involving medium- high-resolution spectroscopy. Spectra were harder ( kT high ∼ 22.8 than 8.4 keV), while mass rate increased by ∼35 times (1.7 × 10 16 g s −1 ) as compared to quiescence. bolometric luminosity...
Abstract Objective: The objective of this study was to evaluate the differences in brain activity between expert surgeons and novice medical residents based on electroencephalography (EEG). first sub-goal assess Microstate EEGlab toolbox BCIlab toolboxes for data analysis classification topographical features microstate-based Common Spatial Pattern (CSP) analysis. Then, second compare CSP with conventional regularized approach.Methods: After IRB approval, ten 13 were recruited at University...
ABSTRACT We present a simultaneous broad-band analysis of X-ray data obtained with the XMM–Newton and Nuclear Spectroscopic Telescope Array (NuSTAR) for asynchronous polar source, CD Ind. The spin-folded light curve in soft 0.3–3.0 keV band shows single broad hump-like structure superimposed occasional narrow dips, indicating single-pole accretion model complex intrinsic absorber. Lack strong modulation folded above 3 reveals that emission from corresponding zone post-shock region (PSR)...
Optical neuroimaging is a promising tool to assess motor skills execution. Especially, functional near-infrared spectroscopy (fNIRS) enables the monitoring of cortical activations in scenarios such as surgical task fNIRS data sets are typically preprocessed derive few biomarkers that used provide correlation between and behavior. Meanwhile, Deep Learning methodologies have found great utility processing complex spatiotemporal for classification or prediction tasks. Here, we report on...
We present the broadband (0.3-40.0 keV) X-ray analysis of a unique intermediate polar Paloma using simultaneous data from XMM-Newton and NuSTAR observatories. The power spectra show strong modulations over orbital period compared to spin period. orbit folded lightcurves single broad hump like structure with dips for soft medium X-rays (0.3-10.0 keV). energy dependent at $\phi \sim 0.16$ $0.5$ arise due complex intrinsic absorber, enough have effect well around 15 keV. absorber could...
We report observations of the optical counterpart long gamma-ray burst (LGRB) GRB 230812B, and its associated supernova (SN) SN 2023pel. The proximity ($z = 0.36$) high energy ($E_{\gamma, \rm{iso}} \sim 10^{53}$ erg) make it an important event to study as a probe connection between massive star core-collapse relativistic jet formation. With phenomenological power-law model for afterglow, we find late-time flattening consistent with presence SN. 2023pel has absolute peak $r$-band magnitude...
Abstract The mechanism of action for the cerebral vasculature hemodynamic response to electric field effects during transcranial direct current stimulation (tDCS) has been less explored. We postulate that such a mechanistic understanding cerebrovascular reactivity (CVR) tDCS can facilitate adequate dosing cognitive rehabilitation in mild impairment and dementia as well motor stroke traumatic brain injuries. This study presents system identification approach evaluate CVR under high-definition...
Abstract The physiological origin of the aperiodic signal present in electrophysiological recordings, called 1/f neural noise, is unknown; nevertheless, it has been associated with health and disease. power spectrum slope, -a a , postulated to be related dynamic balance between excitation (E) inhibition (I). Our study found that human cerebral organoids grown from induced pluripotent stem cells (iPSCs) Schizophrenia patients (SCZ) showed structural changes altered elasticity compared normal...
Abstract The Fundamentals of Laparoscopic Surgery (FLS) training module is designed to provide essential surgical skills. During skill the FLS "suturing and intracorporeal knot-tying" task (FLS complex task) – most difficult among five psychomotor tasks, error-related chain mental processes postulated depend on level leading a difference in contextual switching brain states error commission between experts novices. So, this study investigated changes using simultaneously acquired functional...
Mild traumatic brain injury (TBI) is common and associated with a spectrum of symptoms, which usually resolve within 3 months. But 5%–15% patients are left chronic disabling symptoms challenge the current construct mTBI. Increasingly mTBI has been subject legal cases where neu- rologists have ensnared. The main reason for such challenges lack clarity in definition prognosis. heavily dependent on Mayo classification Brain Injury Assessment, Post-traumatic amnesia (PTA) often taken as...
