Influenza A viruses (IAVs) continuously challenge the poultry industry and human health. Elucidation of host factors that modulate IAV lifecycle is vital for developing antiviral drugs vaccines. In this study, we infected A549 cells with IAVs found protein contactin-1 (CNTN1), a member immunoglobulin superfamily, enhanced viral replication. Bioinformatic prediction experimental validation indicated expression CNTN1 was reduced by microRNA-200c (miR-200c) through directly targeting. We...

Acute lymphoblastic leukemia (ALL), the most common childhood malignancy, is characterized by recurring structural chromosomal alterations and genetic alterations, whose detection critical in diagnosis, risk stratification prognostication. However, mechanisms that give rise to ALL remain poorly understood.Using next-generation sequencing (NGS) matched germline tumor samples from 140 pediatric Chinese patients with ALL, we landscaped gene mutations estimated mutation frequencies this...

Influenza A viruses (IAVs) are single-stranded negative-sense RNA that continually challenge animal and human health. In IAV-infected cells, host RNA-binding proteins play key roles in the life cycle of IAV by directly binding to viral RNA. Here, we examined role protein nucleophosmin-1 (NPM1) replication. We found that, as a nucleolar phosphoprotein, NPM1 binds (vRNA) inhibits replication various subtypes IAV. vRNA competitively reduces assembly ribonucleoprotein complex polymerase...

Pedestrian detection for complex scenes suffers from pedestrian occlusion issues, such as occlusions between pedestrians. As well-known, compared with the variability of human body, shape a head and their shoulders changes minimally has high stability. Therefore, is an important research area in field detection. The translational invariance neural network enables us to design deep convolutional network, which means that, even if appearance location target changes, it can still be recognized...

The rapid development of positioning technology produces an extremely large volume spatio-temporal data with various geometry types such as point, line string, polygon, or a mixed combination them. As one the most basic but time-consuming operations, k nearest neighbors join (kNN join) has attracted much attention. However, existing works for kNN either ignore temporal information consider point only.

A special type of geometric situation in ensembles non-intersecting paths occurs when the trajectories are required to be nonnegative so that limit shape becomes tangential hard-edge $0$. The local fluctuation is governed by universal hard edge tacnode process, which also arises from some tiling problems. It aim this work explore integrable structure and asymptotics for gap probability thinned/unthinned process over $(0,s)$. We establish an integral representation terms Hamiltonian...
