This paper proposes a novel Subdivision-Fusion Model (SFM) to recognize human actions. In most action recognition tasks, overlapping feature distribution is a common problem leading to overfitting. In the subdivision stage of the proposed SFM, samples in each category are clustered. Then, such samples are grouped into multiple more concentrated subcategories. Boundaries for the subcategories ar...

abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...

background: parathyroid hormone (pth) secreted by parathyroid glands regulates the metabolism of calcium and phosphorus in bone and kidney. thereby, it can stimulate bone formation, and is a promising agent in the treatment of osteoporosis. mature form of pth consists of 84 amino acids; however, the first 34 residues of pth cover the majority of hormonal action. methods: in this study, the fusi...

In this paper we present Fusion-GCN, an approach for multimodal action recognition using Graph Convolutional Network (GCNs). Action methods based around (GCNs) recently yielded state-of-the-art performance skeleton-based recognition. With propose to integrate various sensor data modalities into a graph that is trained GCN model multi-modal Additional measurements are incorporated the representa...

Chromaffin cells of the adrenal medulla are innervated by the sympathetic nervous system. Stimulation causes chromaffin cells to fire action potentials, leading to the exocytosis of various classes of transmitters into the circulation. Low-frequency electrical stimulation (action potentials delivered at 0.5 Hz) causes adrenal chromaffin cells to selectively release catecholamines through a kiss...

This paper presents an extension to our previously developed fusion framework [10] involving a depth camera and an inertial sensor in order to improve its view invariance aspect for human action recognition applications. A computationally efficient view estimation based on skeleton joints is considered in order to select the most relevant depth training data when recognizing test samples. Two c...

Why are these synapses special? Because the electrical signals they transmit are not the same as those in other parts of the brain. Conventional synapses convey information arriving as a ‘pulse code’; action potentials lasting a few milliseconds trigger a transient burst of vesicle fusion and the amplitude of the action potential is fixed. But ribbon synapses transmit ‘analogue signals’, such a...

Synaptic vesicle fusion in brain synapses occurs in phases that are either tightly coupled to action potentials (synchronous), immediately following action potentials (asynchronous), or as stochastic events in the absence of action potentials (spontaneous). Synaptotagmin-1, -2, and -9 are vesicle-associated Ca2+ sensors for synchronous release. Here we found that double C2 domain (Doc2) protein...
