Here we report on the fabrication and characterization of temperature-responsive electrospun nanofiber meshes using N-isopropylacrylamide homopolymer (PNIPAAm). The effect of molecular weight on fiber formation and their thermoresponsive shrinking/dissolution behaviors were investigated. The PNIPAAm fiber meshes showed much faster temperature-dependent shrinking or dissolution than that of its ...

Synthetic biology is an interdisciplinary science, combining engineering and biological principles to design and construct new biological entities. Not only is synthetic biology useful for understanding life’s complex circuitries, this discipline has many practical applications such as modifying biological pathways to produce nanoparticles, proteins and other molecules for specific uses. As a r...

considering its central role in energy metabolism in almost all eukaryotes, the mitochondrion is an amazingly plastic organelle, both evolutionarily and functionally. the few genes that the mitochondrial genome (mito chondrial DNa; mtDNa) encodes are clearly bacterial in origin —emanating from the α-proteobacterial lineage—supporting the widely held view that the mitochondrion is the evolutiona...

PURPOSE To evaluate the shear bond strength (SBS), adhesive remnant index (ARI), and microleakage of low-shrinking and conventional composites used as an orthodontic bracket bonding adhesive. MATERIALS AND METHODS A hundred twenty non-caries human premolars, extracted for orthodontic purposes, were used in this study. Sixty of them were separated into two groups. Brackets were bonded to the t...

A study of magnetohydrodynamics (MHD) axisymmetric stagnation point flow with viscous dissipation and heat transfer in an electrically conducting laminar steady viscous incompressible fluid over a heated axisymmetric shrinking surface is presented. The governing partial differential equations (PDEs) are reduced to non linear ordinary differential equations (ODEs) in dimensionless form using sui...

The valveless micropump based on dual synthetic jets is a potential fluid pumping device that has the ability to transport continuously. In order improve performance of this device, novel continuous with Tesla structure was proposed by combining double symmetrical nozzle and actuator. mechanism its flow field characteristics were analyzed, combined numerical simulation PIV experiment. compared ...

The L2-regularized hinge loss kernel SVM could be the most important and most studied machine learning algorithm. Unfortunately, its computational training time complexity is generally unsuitable for big data. Empirical runtimes can however often be reduced using shrinking heuristics on the training sample set, which exploit the fact that non-support vectors do not affect the decision boundary....

Time Shrinking denotes the psycho-acoustic shrinking effect of a short interval on one or several subsequent longer intervals. Its effectiveness in the domain of speech perception has so far not been examined. Two perception experiments clearly suggest the influence of relative duration patterns triggering time shrinking on the perception of tempo and rhythmical isochrony or rather “evenness”. ...
