Prevalence and Impact of Stress in the Indian Population: A Retrospective Survey Analysis
Post-COVID-19 pandemic, individuals are experiencing various forms of stress. This study assessed the prevalence of stress among Indian adults, examined its physical and psychological impacts, and investigated stress management strategies, aiming to fill existing gaps in research. This retrospective observational study utilized an online survey from March 16, 2023, to July 30, 2023, using snowball sampling to target the Indian population. Respondents aged ≥18 years participated in the study. The survey collected data on demographic information, self-reported stress levels, and Perceived Stress Scale (PSS) scores. The chi-square test was applied for statistical analysis, and results with a p-value under 0.05 were considered significant. Among 1,479 respondents (638 males, 841 females; mean age: 23.7±7.7 years), 76.0% of respondents resided in Karnataka. Out of 1,479 respondents, 9.6% experienced mild stress, 84.9% experienced moderate stress, and 5.5% experienced severe stress according to the PSS. Females experienced significantly higher stress levels when compared with males (p=0.047), but both experienced moderate stress levels. Financial problems (20.7%) and studies (36.4%) were the most common stressors among respondents. They most frequently manage stress through personal strategies, such as sleeping and listening to music. The present study\u27s findings indicate that, following the COVID-19 health crisis, moderate levels of stress are significantly prevalent in the Indian population, primarily due to academic and job-related pressures
The types of Mott insulator
There are two classes of Mott insulators in nature, distinguished by their
responses to weak doping. With increasing chemical potential, Type I Mott
insulators undergo a first order phase transition from the undoped to the doped
phase. In the presence of long-range Coulomb interactions, this leads to an
inhomogeneous state exhibiting ``micro-phase separation.'' In contrast, in Type
II Mott insulators charges go in continuously above a critical chemical
potential. We show that if the insulating state has a broken symmetry, this
increases the likelihood that it will be Type I. There exists a close analogy
between these two types of Mott insulators and the familiar Type I and Type II
superconductors
A Solvable Regime of Disorder and Interactions in Ballistic Nanostructures, Part I: Consequences for Coulomb Blockade
We provide a framework for analyzing the problem of interacting electrons in
a ballistic quantum dot with chaotic boundary conditions within an energy
(the Thouless energy) of the Fermi energy. Within this window we show that the
interactions can be characterized by Landau Fermi liquid parameters. When ,
the dimensionless conductance of the dot, is large, we find that the disordered
interacting problem can be solved in a saddle-point approximation which becomes
exact as (as in a large-N theory). The infinite theory shows a
transition to a strong-coupling phase characterized by the same order parameter
as in the Pomeranchuk transition in clean systems (a spontaneous
interaction-induced Fermi surface distortion), but smeared and pinned by
disorder. At finite , the two phases and critical point evolve into three
regimes in the plane -- weak- and strong-coupling regimes separated
by crossover lines from a quantum-critical regime controlled by the quantum
critical point. In the strong-coupling and quantum-critical regions, the
quasiparticle acquires a width of the same order as the level spacing
within a few 's of the Fermi energy due to coupling to collective
excitations. In the strong coupling regime if is odd, the dot will (if
isolated) cross over from the orthogonal to unitary ensemble for an
exponentially small external flux, or will (if strongly coupled to leads) break
time-reversal symmetry spontaneously.Comment: 33 pages, 14 figures. Very minor changes. We have clarified that we
are treating charge-channel instabilities in spinful systems, leaving
spin-channel instabilities for future work. No substantive results are

Measurement of the Bottom contribution to non-photonic electron production in collisions at =200 GeV
The contribution of meson decays to non-photonic electrons, which are
mainly produced by the semi-leptonic decays of heavy flavor mesons, in
collisions at 200 GeV has been measured using azimuthal
correlations between non-photonic electrons and hadrons. The extracted
decay contribution is approximately 50% at a transverse momentum of GeV/. These measurements constrain the nuclear modification factor for
electrons from and meson decays. The result indicates that meson
production in heavy ion collisions is also suppressed at high .Comment: 6 pages, 4 figures, accepted by PR
Longitudinal double-spin asymmetry and cross section for inclusive neutral pion production at midrapidity in polarized proton collisions at sqrt(s) = 200 GeV
We report a measurement of the longitudinal double-spin asymmetry A_LL and
the differential cross section for inclusive Pi0 production at midrapidity in
polarized proton collisions at sqrt(s) = 200 GeV. The cross section was
measured over a transverse momentum range of 1 < p_T < 17 GeV/c and found to be
in good agreement with a next-to-leading order perturbative QCD calculation.
The longitudinal double-spin asymmetry was measured in the range of 3.7 < p_T <
11 GeV/c and excludes a maximal positive gluon polarization in the proton. The
mean transverse momentum fraction of Pi0's in their parent jets was found to be
around 0.7 for electromagnetically triggered events.Comment: 6 pages, 3 figures, submitted to Phys. Rev. D (RC
Dentoronics: The Future of Dentistry Towards Robotics
Dentistry has seen massive improvements and advancements from the traditional techniques to the digital world that has widened the scope of dental treatment and procedures. Bio-robots application in oral diagnosis and treatment models can promote new avenue of technological innovation. This abstract explores the domain of dentoronics, where robotics and AI converge to reshape the future of dental care. While the Dentoronics revolution holds immense promise, challenges such as cost, regulatory approvals, and ethical considerations need to be addressed. Currently robots are used in basic and applied research in various specialized fields where tooth-crown preparation robots, drilling robots, implant surgery robots, teeth arrangement robots, arch wire bending robots are being developed. Stimulation-based training can benefit and bring the revolution in dentistry. Nevertheless, Dentoronics is poised to redefine the future of dentistry by providing safer, more efficient, and inclusive oral healthcare solutions, ultimately improving the well-being of countless individuals worldwide. As the field continues to evolve, embracing the robots are used in basic and applied research
Measurement of charm production at central rapidity in proton-proton collisions at TeV
The -differential production cross sections of the prompt (B
feed-down subtracted) charmed mesons D, D, and D in the rapidity
range , and for transverse momentum GeV/, were
measured in proton-proton collisions at TeV with the ALICE
detector at the Large Hadron Collider. The analysis exploited the hadronic
decays DK, DK, DD, and their charge conjugates, and was performed on a
nb event sample collected in 2011 with a
minimum-bias trigger. The total charm production cross section at TeV and at 7 TeV was evaluated by extrapolating to the full phase space
the -differential production cross sections at TeV
and our previous measurements at TeV. The results were compared
to existing measurements and to perturbative-QCD calculations. The fraction of
cdbar D mesons produced in a vector state was also determined.Comment: 20 pages, 5 captioned figures, 4 tables, authors from page 15,

Particle-yield modification in jet-like azimuthal di-hadron correlations in Pb-Pb collisions at = 2.76 TeV
The yield of charged particles associated with high- trigger
particles ( GeV/) is measured with the ALICE detector in
Pb-Pb collisions at = 2.76 TeV relative to proton-proton
collisions at the same energy. The conditional per-trigger yields are extracted
from the narrow jet-like correlation peaks in azimuthal di-hadron correlations.
In the 5% most central collisions, we observe that the yield of associated
charged particles with transverse momenta GeV/ on the
away-side drops to about 60% of that observed in pp collisions, while on the
near-side a moderate enhancement of 20-30% is found.Comment: 15 pages, 2 captioned figures, 1 table, authors from page 10,

Reading Ronaldo: contingent whiteness in the football media
Ever since his introduction to the first--team at Manchester United FC, Cristiano Ronaldo Dos Santos Aveiro has been recognised as one of the footballing world’s most stand--out football players. In turn, Ronaldo has drawn the attention of scholars working across a number of disciplines. While sports economists and sociologists of sport, amongst others, have contributed to a growing literature about Ronaldo and the social implications of his on and off--field behaviour, few critical analyses have considered the racialised aspects of Ronaldo’s representations, or how audiences make sense of his racialised or ethnic identity. Using images of Ronaldo, which we presented to and discussed with self--identified physically active white British men, we explore what it is representations and audience interpretations of Ronaldo reveal about the complexities of white male identity formation. We do this to understand better how white male identities can be read and interpreted through and in the context of football. Facilitated by our conception of contingent whiteness, we argue that white British men’s interpretations of Ronaldo’s whiteness are inextricably linked to discourses of ‘race’, masculinities and football
