Abstract The Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM) experiment successfully recorded data 539 days from 2017 August to 2019 February. We report energy spectrum of cosmic-ray protons ISS-CREAM at energies 1.60 × 10 3 6.55 5 GeV. measured deviates a single power law. A smoothly broken power-law fit data, including statistical and systematic uncertainties, shows spectral index change 9.0 GeV 2.57 ± 0.03 2.82 0.02 with significance greater than σ . This...
Online fandom communities (OFCs) provide a convenient space for fans to create, collect, and discuss the content of their mutual interest (e.g., music artists). Real-world events could frequently attract outsiders join OFCs, providing both opportunity expand fan base challenges manage community. However, it is unclear that how influxes newcomers would influence development OFCs what user behaviors may be correlated with future engagement. To fill this gap, we took as focus, quantitatively...

In 3<sup>rd</sup> generation CT systems projection data, generated by X-rays emitted from a single source and passing through the imaged object, are acquired detector covering entire field of view (FOV). Novel system architectures employing distributed sources [1,2] could extend axial coverage, while removing cone-beam artifacts improving spatial resolution dose. The can be in plane and/or longitudinal direction. We investigate statistical iterative reconstruction multi-axial with simulated...

Visual Word Sense Disambiguation (VWSD) is a multi-modal task that aims to select, among batch of candidate images, the one best entails target word's meaning within limited context. In this paper, we propose retrieval framework maximally leverages pretrained Vision-Language models, as well open knowledge bases and datasets. Our system consists following key components: (1) Gloss matching: bi-encoder model used match contexts with proper senses words; (2) Prompting: matched glosses other...

One of the consequences having a high-density calorimeter as part an experiment is large number secondary shower particles generated in -- some which scatter back up towards charge measurement devices. This so-called "backscatter effect" can interfere severely with accurate primary nucleus, especially at high energies, backscattered increases incident energy. In this analysis, we study effect on particle identification by simulating ISS-CREAM instrument model detector response using GEANT3...
Image-to-image translation (I2I) is defined as a computer vision task where the aim to transfer images in source domain target with minimal loss or alteration of content representations. Major progress has been made since I2I was proposed invention variety revolutionary generative models. Among them, GAN-based models perform exceptionally well they are mostly tailor-made for specific domains tasks. However, few works method artistic domain. In this project, I propose Semantic-aware Mask...
