On the synthesis of heavy nuclei in protomagnetar outflows and implications for ultra-high energy cosmic rays

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Mukul Bhattacharya, Shunsaku Horiuchi, Kohta Murase, , | Summary: It has been suggested that strongly magnetised and rapidly rotating protoneutron stars (PNSs) may produce long duration gamma-ray bursts (GRBs) originating from stellar core collapse. We explore the steady-state properties and heavy element nucleosynthesis in neutrino-driven winds from […]

Learning to Disentangle Scenes for Person Re-identification

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, Xiujun Shu, | Summary: There are many challenging problems in the person re-identification (ReID) task, such as the occlusion and scale variation. Existing works usually tried to solve them by employing a one-branch network. This one-branch network needs to be robust […]

Exploiting Robust Unsupervised Video Person Re-identification

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, Xiujun Shu, | Summary: Unsupervised video person re-identification (reID) methods usually depend on global-level features. And many supervised reID methods employed local-level features and achieved significant performance improvements. However, applying local-level features to unsupervised methods may introduce an unstable performance. To […]

Provable properties of asymptotic safety in $f(R)$ approximation

Posted by klaurent Stanford

Kavli Affiliate: R. Morris | First 5 Authors: Alex Mitchell, Tim R. Morris, Dalius Stulga, , | Summary: We study an $f(R)$ approximation to asymptotic safety, using a family of non-adaptive cutoffs, kept general to test for universality. Matching solutions on the four-dimensional sphere and hyperboloid, we prove properties of any such global fixed point […]

Video Text Tracking With a Spatio-Temporal Complementary Model

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Yuzhe Gao, Xing Li, Jiajian Zhang, Yu Zhou, Dian Jin | Summary: Text tracking is to track multiple texts in a video,and construct a trajectory for each text. Existing methodstackle this task by utilizing the tracking-by-detection frame-work, i.e., detecting the text instances in each frame andassociating the […]

KMT-2021-BLG-0912Lb: A microlensing super Earth around a K-type star

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Cheongho Han, Ian A. Bond, Jennifer C. Yee, Weicheng Zang, Michael D. Albrow | Summary: The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpose of identifying the origin of […]

Outer Automorphism Anomalies

Posted by Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama, | Summary: We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for $SU(N)$ and parities for $SO(2r)$. We emphasize the inequivalence between two versions of charge conjugation for $SU(N)$ symmetries, and […]

Universal fine grained asymptotics of free and weakly coupled Quantum Field Theory

Posted by klaurent Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Tom Melia, Sridip Pal, , | Summary: We give a rigorous proof that in any free quantum field theory with a finite group global symmetry $mathrm{G}$, on a compact spatial manifold, at sufficiently high energy, the density of states $rho_alpha(E)$ for each irreducible representation $alpha$ […]
