New Selective Block Matching Searching Algorithm Based on Block Discriminator Values For Motion Estimation [PDF]

open access: yesEngineering and Technology Journal, 2015
In this paper, a new, fast and efficient selective block matching algorithm based on block discriminator values is suggested. The searching scheme consists of three stages: block discriminator values calculations, open full window then cascaded selection

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

A Vision-Based Procedure with Subpixel Resolution for Motion Estimation

open access: yesSensors
Vision-based motion estimation for structural systems has attracted significant interest in recent years. As the design of robust algorithms to accurately estimate motion still represents a challenge, a multi-step framework is proposed to deal with both ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Modeling of nano piezoelectric actuator based on block matching algorithm with optimal block size

open access: yes, 2013
In this paper, a new hysteresis modeling method based on an improved sub-pixel blocking matching algorithm with an optimal block size and the Preisach model is proposed to model the hysteresis behavior of a nano piezoelectric actuator (PA) on nano scale ...

Stereo Vision for 3D Measurement in Robot Systems

open access: yesJournal of Engineering and Sustainable Development, 2013
The major obstacle in the application of stereo vision to extract 3D information is the error in disparity map and highly computational cost at conventional computers.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

open access: yesMolecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Motion estimation algorithm using 2 bit-depth pixel and fuzzy quantization

open access: yesTongxin xuebao, 2013
A motion estimation algorithm was proposed using 2 bit-depth pixels. The reduction of pixel depth was first formalized by two successive steps, namely interval partitioning and interva mapping.
