Strong electric field annihilation by particle-antiparticle pair creation, also known as the Schwinger effect, is a non-perturbative prediction of quantum electrodynamics. Its experimental demonstration remains elusive, threshold fields are extremely strong and beyond current reach. Here, we propose mesoscopic variant effect in graphene, which hosts Dirac fermions with an approximate electron-hole symmetry. Using transport measurements, report on universal 1d-Schwinger conductance at...
Hypomanic symptoms depending on anatomical location of contacts are reported in patients with Parkinson9s disease (PD) treated by deep brain stimulation (DBS) the subthalamic nucleus (STN). However, underlying cortical and subcortical dysfunction is debated. In this study, five PD implanted DBS–STN who presented reversible reproducible hypomanic after specific 'manic' were investigated. assessed using Bech Rafaelsen Mania Scale (MAS). Three dimensional 'euthymic' contacts, matching...
Background A strong association between workplace bullying and subsequent anxiety depression, indicated by empirical research, suggests that is an aetiological factor for mental health problems.
We report the case of a patient who had benefited from bilateral subthalamic nucleus deep brain stimulation for Parkinson's disease and presented acute reproducible manic behaviour when stimulated mainly in substantia nigra. A positron emission tomography scan showed an activation right dorsolateral prefrontal inferior temporal cortex, left anterior cingulate cortex deactivation insula. This suggests that changes cortical related to mania are subcortically driven, involving notably
Background Executive functions are linked to tobacco dependence and craving. In this cross-sectional study, we assessed the impact of three executive functions: updating, inhibition shifting processes on craving dependence. Method 134 consumers were included in study: 81 moderately (Fagerström score <7) 53 heavily dependent >7). Dependence was with Fagerström test questionnaire (TCQ 12). We used Stroop Hayling measure inhibition, Trail Making Test n-back updating processes. A multivariate...
Cognitive bias modification (CBM) training has been considered a promising and effective intervention tool for reducing cognitive biases toward alcohol. However, the link between process actual behavior remains statistically insignificant because computerized tasks do not have sufficient ecological validity suffer from high dropout rates. The recent development of 'serious games' shown encouraging results in maintaining adherence to health-related interventions. We aim evaluate CBM program...
$1/f$ electronic noise is a conductance fluctuation, expressed in terms of mobility ``$\ensuremath{\alpha}$-noise'' by Hooge and Kleinpenning. Understanding this graphene key for high-performance electronics. Early investigations pointed out deviation from the standard formula, with free-carrier density substituted constant ${n}_{\mathrm{\ensuremath{\Delta}}}\ensuremath{\sim}{10}^{12}\phantom{\rule{0.28em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}2}$. Here we investigate hBN-encapsulated...
One of the intrinsic drift velocity limit quantum Hall effect is collective magneto-exciton (ME) instability. It has been demonstrated in bilayer graphene (BLG) using noise measurements. We reproduce this experiment monolayer (MLG), and show that same mechanism carries a direct relativistic signature on breakdown velocity. Based theoretical calculations MLG- BLG-ME spectra, we Doppler-induced instabilities manifest for ME phase determined by universal value conductivity, set conductance.
