This paper demonstrates that applying Deep Neural Networks to a 2x2 array of linearly-graded Silicon Photomultipliers significantly improves position resolution and linearity while increasing the number of resolvable pixels by a factor of 5.7 to 12.1 compared to traditional reconstruction methods.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper presents a rapid, GPU-parallelized array-based algorithm that enables real-time, high-fidelity particle coincidence detection and centroiding for TimePix3-based velocity map imaging instruments, achieving processing speeds 25 times faster than data acquisition while outperforming traditional delay line anode detectors in discriminating simultaneous hits.
This paper establishes a per-pixel optogeometric throughput factor, , to explicitly map scene radiance to incident photon counts at the detector level, thereby defining the fundamental shot-noise-limited signal-to-noise ratio bounds for individual pixels based on optical geometry.
This paper outlines recent enhancements to the VOXES Von Hamos spectrometer, including the integration of an energy-dispersive detection line, a liquid-sample holder, and a Y-shaped support for transmission geometry, which collectively expand its capabilities for high-resolution, automated laboratory XES and XAS studies.
This paper presents a radiation-hardened 130 nm CMOS delta-sigma current digitizer capable of achieving over 200 dB dynamic range and sub-picoampere resolution for beam loss monitoring, while maintaining a 10 µs response time for machine protection and demonstrating robust performance up to 100 Mrad total ionizing dose.
This paper presents a novel two-dimensional shift and rotation method that leverages the correlation between time-of-flight mass-squared and ionization energy loss to significantly improve charged pion and kaon identification in heavy-ion collisions, extending the reliable measurement range to approximately 3 GeV/ while maintaining over 98% purity and preserving elliptic flow consistency.
This paper introduces a new, computationally efficient matrix-based algorithm for determining antineutrino directionality in segmented reactor detectors, offering improved accuracy and error analysis over conventional methods while identifying optimal segmentation scales for low-count regimes.
This paper presents a diamond-based metal-insulator-metal campanile probe that adiabatically compresses mid-infrared light into sub-wavelength volumes, enabling high-efficiency, high-resolution mapping of locally driven photocurrents in graphene and offering a robust platform for exploring low-energy carrier dynamics in atomically thin materials.
Using a Ramsey-type apparatus with cold neutrons, researchers analyzed 24 hours of data to find no evidence of oscillating axion-like dark matter, thereby establishing the most stringent limits to date on the coupling between axion-like particles and gluons within a specific mass range.
