The Gabor expansion is a mathematical tool, which provides a joint time-frequency representation of a given signal by decomposing it into time-frequency elementary signals called Gabor atoms. It has been used in a variety of signal processing applications, including biomedical signal processing. In this paper we present a time-frequency masking technique based on Gabor expansion for both heart ...

Planning optimal paths for large numbers of robots is computationally expensive. In this paper, we introduce a new framework for multirobot path planning called subdimensional expansion, which initially plans for each robot individually, and then coordinates motion among the robots as needed. More specifically, subdimensional expansion initially creates a one-dimensional search space embedded i...

We consider the long-time behavior of solutions to massless Dirac equation coupled a Coulomb potential. For nice enough initial data, we find joint asymptotic expansion for near null and future infinities characterize explicitly decay rates seen in expansion. This paper can be viewed as successor previous work on expansions radiation field [BVW15], [BVW18], [BM19]. The key new elements are prop...

network expansion studies normally offer new power lines, new substations or expansion of existing substations. they are generally proposed based on technical requirements, but financial restrictions are not considered. because of financial restrictions, ranking of network expansion plans is required. in this paper an algorithm for such ranking, based on technical and financial view points and ...

Rice (Oryza sativa) leaf angle is determined by lamina joint and is an important agricultural trait determining leaf erectness and, hence, the photosynthesis efficiency and grain yield. Genetic studies reveal a complex regulatory network of lamina joint development; however, the morphological changes, cytological transitions, and underlying transcriptional programming remain to be elucidated. A...

This paper addresses a biped balancing task in which an unknown external force is exerted, using so-called ‘ankle strategy’ model. When an external force is periodic, a human adaptively maintains the balance, next learns how much force should be produced at the ankle joint from its repeatability, and finally memorized it as a motion pattern. To acquire motion patterns with balancing, we propose...

Management and protection of proprietary intangible assets such as technology and management skills is important for firms considering international expansion via joint ventures. Joint venture partners have incentives to appropriate intangible property. Also many governments have instituted policies to help domestic firms maximise technology spillovers. Some require foreign firms interested in ...

Dysregulated functions of B1 cells have been implicated in the disease progression of various autoimmune disorders, but it remains largely unclear whether B1 cells are involved in the pathogenesis of autoimmune arthritis. In this study, we found that peritoneal B1a cells underwent proliferation and migrated to the inflamed joint tissue with upregulated RANKL expression during collagen-induced a...

OBJECTIVE To assess the nature of T cell receptor (TCR) utilisation by CD4 T cells in the rheumatoid joint. METHODS Sequencing of the joining (NDJ) region of TCR beta chain mRNA isolated from synovial fluid CD4 T cells was performed in three patients in order to determine if oligoclonal expansion of particular sequences was present. Two patients were studied longitudinally to determine if the...

Operative treatment modalities for calcaneal fracture are still controversial. The outcome of intra-articular calcaneal fracture is mainly influenced by the soft tissue and the subtalar joint. Percutaneous method of internal fixation has been attempted to avoid the problems. Patients with displaced intra-articular calcaneal fracture types IIA, IIB and IIC were treated by initial distraction of ...
