Although great progress has been made in generic object detection by advanced deep learning techniques, detecting small objects from images is still a difficult and challenging problem the field of computer vision due to limited size, less appearance, geometry cues, lack large-scale datasets targets. Improving performance wider significance many real-world applications, such as self-driving cars, unmanned aerial vehicles, robotics. In this article, first-ever survey recent studies...
Based on the demands of compact heat exchangers and micro cooling channels applied for aviation thermal protection aero-engines, elbow local flow resistance characteristics supercritical pressure fuel RP-3 flowing in adiabatic horizontal serpentine tubes with inner diameter 1.8 mm mass flux 1179 kg/(m2·s) were experimentally studied. The long-short-tube method was used to obtain drop from total tube drop, effects system pressures (P/Pc = 1.72–2.58) geometry parameters including bend numbers...

Melatonin functions as a crucial mediator of sterile neuroinflammation; however, the underlying mechanisms remain poorly understood. Dysfunctional mitochondria, main source reactive oxygen species, are impacted in inflammation activation. This study aimed to examine effect melatonin on via elimination damaged mitochondria after controlled cortical impact, an vivo model traumatic brain injury (TBI). Here, we demonstrated that inhibition mitophagy, selective degradation by autophagy, markedly...
Mitochondrial energy production is essential for normal brain function. Traumatic injury (TBI) increases demands, results in the activation of mitochondrial respiration, associated with enhanced generation reactive oxygen species. This chain events triggers neuronal apoptosis via oxidation a mitochondria-specific phospholipid, cardiolipin (CL). One pathway through which cells can avoid elimination damaged mitochondria by mitophagy. Previously, we showed that externalization CL to surface...
Prokineticin-2 (Prok2) is an important secreted protein likely involved in the pathogenesis of several acute and chronic neurological diseases through currently unidentified regulatory mechanisms. The initial mechanical injury neurons by traumatic brain triggers multiple secondary responses including various cell death programs. One these ferroptosis, which associated with dysregulation iron thiols culminates fatal lipid peroxidation. Here, we explore role Prok2 neuronal ferroptosis vitro...
Point cloud registration is a fundamental problem in 3D computer vision. Outdoor LiDAR point clouds are typically large-scale and complexly distributed, which makes the challenging. In this paper, we propose an efficient hierarchical network named HRegNet for out-door registration. Instead of using all points clouds, performs on hierarchically extracted keypoints descriptors. The overall framework combines reliable features deeper layer precise position information shallower layers to...
Gastrointestinal dysfunction is one of several physiologic complications in patients with traumatic brain injury (TBI). TBI can result increased intestinal permeability resulting from apoptosis epithelial cells, which contain a large number mitochondria for persisting barrier function. Autophagy damaged (mitophagy) controls the quality and regulates cellular homeostasis. However, exact mechanism mitophagy that underlies pathological changes induced by unknown. Here, we report decreases cell...
Programmed cell death is an important biological process that plays indispensable role in traumatic brain injury (TBI). Inhibition of necroptosis, a type programmed death, pivotal neuroprotection and preventing associated inflammatory responses. Our results showed necroptosis occurred human tissues after TBI. Necroptosis was also induced by controlled cortical impact (CCI) rat model TBI accompanied high translocation high-mobility group box-1 (HMGB1) to the cytoplasm. HMGB1 then passed...

Rotation estimation plays a fundamental role in many computer vision and robot tasks. However, efficiently estimating rotation large inputs containing numerous outliers (i.e., mismatches) noise is recognized challenge. Many robust methods have been designed to address this Unfortunately, existing are often inapplicable due their long computation time the risk of local optima. In paper, we propose an efficient method. Specifically, our method first investigates geometric constraints involving...
Point cloud registration is a fundamental problem in 3D computer vision. Previous learning-based methods for LiDAR point can be categorized into two schemes: dense-to-dense matching and sparse-to-sparse methods. However, large-scale outdoor clouds, solving dense correspondences time-consuming, whereas sparse keypoint easily suffers from detection error. In this paper, we propose SDMNet, novel Sparse-to-Dense Matching Network registration. Specifically, SDMNet performs sequential stages:...
Radar is among the most popular sensors in modern Intelligent Transportation Systems (ITSs), enabling weather-robust perception. The orientation and position of traffic radar relative to ITS coordinate system are necessary for perception fusion ITSs. However, due unknown target association, sparseness noisiness measurements, robust accurate extrinsic calibration challenging. In this paper, we propose a targetless method based on GPS overcome inconvenience during operation, because...
Rotation motion in a three-dimensional physical world refers to an angular displacement of object around specific axis $\mathbb{R}^3$. It is typically formulated as non-linear and non-convex due the nonlinearity nonconvexity $\mathbb{SO}(3)$. However, this paper proposes new perspective that 3D rotation can be expressed by linear system without dropping any constraints increasing singularities. Moreover, two frequent cases, i.e., $\angle\left(\mathbf{R}\boldsymbol{x},\boldsymbol{y}\right)=0$...
