Semantic segmentation in bird's eye view (BEV) is an important task for autonomous driving. Though this has attracted a large amount of research efforts, it still challenging to flexibly cope with arbitrary (single or multiple) camera sensors equipped on the vehicle. In paper, we present BEVSegFormer, effective transformer-based method BEV semantic from rigs. Specifically, our first encodes image features cameras shared backbone. These are then enhanced by deformable encoder. Moreover,...

Topological states emerge at the boundary of solids as a consequence nontrivial topology bulk. Recently, theory predicts topological edge state on single layer transition metal dichalcogenides with 1T' structure. However, its existence still lacks experimental proof. Here, we report direct observations step WTe2 by spectroscopic-imaging scanning tunneling microscopy. A one-dimensional electronic residing is observed, which has spatial extension about 2.5 nm. First principles calculations...

Fuel cells, as one of the most promising technologies in sustainable energy conversion systems, hold great expectations for commercial applications. Cathode oxygen reduction reaction (ORR) kinetics fuel cells are very slow and require a large overpotential to make occur, which greatly limits output cells. Therefore, designing preparing highly active stable ORR catalyst has become challenge. Herein, recent advances platinum‐based platinum‐free materials metal‐based catalysts focused on,...

3D lane detection is an integral part of au-tonomous driving systems. Previous CNN and Transformer-based methods usually first generate a bird's-eye-view (BEV) feature map from the front view image, then use sub-network with BEV as input to predict lanes. Such approaches require explicit transformation between view, which itself still challenging problem. In this paper, we propose CurveFormer, single-stage method that directly calculates pa-rameters can circumvent difficult step....

Unsustainable agricultural land use will lead to an increased risk of soil erosion and degradation. However, few studies have investigated impacts changes in root properties on the detachment process. Therefore, we effects relative contribution capacity. Soil samples were collected from six different types subjected flow scouring under shear stresses ranging 4.98 16.37 Pa. Agricultural influenced distribution surface layer. Root length density, area volume density orchards with no cover,...

Two soluble bipolar host materials (mCP-BPBI and CP-QPBI), comprising different proportions of hole-transporting carbazole electron-transporting benzimidazole, were synthesized. Their thermal, physical, electrochemical properties characterized. The designated bulky star-shaped structures efficiently suppress the direct intramolecular interaction between donor acceptor subunits to give high triplet energies. Through computational studies, varying ratio hole- moieties could significantly...

Introduction Hepatic fibrosis (HF), a progressive chronic liver disease, is serious threat to global public health. The lack of preventive and therapeutic strategies has created an urgent need for effective anti-fibrosis agents. There growing evidence that natural products might provide safe interventions HF. Among them, rhaponticin (RHA), stilbenoid glucoside product isolated from medicinal plants Rheum L. Polygonaceae Juss. many pharmacological activities such as anti-inflammatory,...

Abstract An electron in solid can be dressed by the lattice distortions of surroundings, forming a localized composite quasiparticle called small polaron, whose formation has been customarily attributed to electron-phonon couplings that ion polarization traps excess electron. Here we present theory electron-polarization induced polaron (EPI-SP), which carrier localization happens spontaneously and drives subsequent relaxation. This mechanism is qualitatively different than Mott-Stoneham...

Platelets are the main components supporting coagulation and hemostasis. Nevertheless, no sufficient research has been done on how variations in platelet counts during hospital stays affect aplastic anemia (AA) patients' prognoses. This study proposes to evaluate association between alterations levels illness risk patients with AA using group-based trajectory modeling (GBTM). GBTM was used group based changes levels. Cox regression models were relationship 30-day survival status....

The aim study was to assess effects monoclonal antibody in combination an ixazomib-based regimen on survival patients relapsed/refractory MM (RRMM). Methods. A retrospective included clinical data 65 RRMM admitted from March 2016 2019. were divided according different regimens into two groups: Group A,...

Freestanding single bilayer Bi(111) is a two-dimensional topological insulator with edge states propagating along its perimeter. Given the interlayer coupling experimentally, nature of thin films and impact supporting substrate on topmost Bi are still under debate.

Two types nonmagnetic structures, i.e., conventional zigzag...

Activated brain microglia play a pivotal role in inflammatory and degenerative disorders, mediating immune function producing toxic trophic agents. We previously reported that express neurotrophins neurotrophin-3 (NT-3) increases microglial proliferation phagocytosis, processes associated with cellular activation. However, mechanisms regulating responsiveness to NT-3 expression of activated remain undefined. To investigate governing neurotrophins, we determined whether trk C, the...

Three-dimensional (3D) topological Dirac semimetal, when thinned down to 2D few layers, is expected possess gapped nodes via quantum confinement effect and concomitantly display the intriguing spin Hall (QSH) insulator phase.
