Abstract Animal nervous systems can detect changes in their environments within hundredths of a second. They do so by discerning abrupt shifts sensory neural activity. Many neuroscience studies have employed change-point detection (CPD) algorithms to estimate such But very few suggested that spiking neurons themselves are online detectors. We show leaky integrate-and-fire (LIF) neuron implements an CPD algorithm for compound Poisson process. quantify the performance LIF under various regions...
Inclusive ${\ensuremath{\pi}}^{0}$ and direct-photon cross sections in the kinematic range $3.5<{p}_{T}<12\mathrm{GeV}/c$ with central rapidities ( ${y}_{\mathrm{cm}}$) are presented for $530\mathrm{and}800\mathrm{GeV}/c$ proton beams a $515\mathrm{GeV}/c$ ${\ensuremath{\pi}}^{\ensuremath{-}}$ beam incident on Be targets.

The binding energies of di- hadronic states have been calculated assuming a 'molecular' interaction provided by the asymptotic expression residual confined gluon exchange potential between component hadrons in system. Meson- meson and meson- baryon studied detail mass formula has used to calculate total 'molecules'.

Abstract We report on the calibration and performance of a large lead liquid-argon electromagnetic calorimeter used by experiment E706 at Fermilab. The reconstructed π 0 mass was to calibrate energy response calorimeter. systematic uncertainty in linearity uniformity mean-energy after found be less than ±0.5% for sample data analyzed. Detector characteristics, including sampling fluctuations position resolution, are discussed.
ABSTRACT This paper introduces a novel hybrid approach, termed ZOA‐SNN, for fault detection and identification in converter‐interfaced microgrids. By integrating the Zebra Optimization Algorithm (ZOA) with Spiking Neural Network (SNN) technology, proposed method provides comprehensive solution suitable both grid‐connected autonomous microgrid operation scenarios. The technique effectively isolates faults while maintaining continuity, particularly islanded conditions. When operating mode,...
