Presently the majority of tissue engineering approaches aimed at regenerating bone relies only on post-implantation vascularization. Strategies that include seeding endothelial cells (ECs) on biomaterials and promoting their adhesion, migration and functionality might be a solution for the formation of vascularized bone. Nano/micro-fiber-combined scaffolds have an innovative structure, inspired...

Classification of fiber tracts is an important problem in brain tractography.We propose a supervised algorithm which learns features for anatomically meaningful fiber clusters, from labeled DTI white matter data. The classification is performed at two levels: a) Grey vs White matter (macro level) and b) White matter clusters (micro level). Our approach focuses on high curvature points in the fi...

We present high average power picosecond and nanosecond pulse delivery at 1030 nm and 1064 nm wavelengths respectively through a novel hollow-core Negative Curvature Fiber (NCF) for high-precision micro-machining applications. Picosecond pulses with an average power above 36 W and energies of 92 µJ, corresponding to a peak power density of 1.5 TWcm⁻² have been transmitted through the fiber with...

BACKGROUND Although intrathecal administration of opioids produces antinociceptive effects in the spinal cord, it has not been established whether intrathecal opioid application more effectively terminates C fiber-mediated pain than A fiber-mediated pain. Here, the authors focus on the differences in opioid actions on Adelta- and C-afferent responses. METHODS Using the whole cell patch clamp ...

Recent advances of interfacial micromechanics in fiber reinforced composites using micro-Raman spectroscopy are given. The faced mechanical problems for interface design in fibrous composites are elaborated from three optimization ways: material, interface, and computation. Some reasons are depicted that the interfacial evaluation methods are difficult to guarantee the integrity, repeatability,...

In this sample paper, we describe and provide a novel Microstructured optical fiber for FTTH, which has 12 holes in its cladding. The fiber has very good bending properties. The bending losses of the novel Micro-structured fibers at the conditions of 2mm bendingradius are less than 0.1 dB at 1550 nm wavelength. The typical PMD of the novel Microstructure fibers are 0.062ps/km1/2.The splice loss...

Dual-coated optical fibers provide easier stripping and less sensitivity to micro-bending. Despite a record of success in the field, dual-coated fibers can still pose a challenge within the manufacturing environment since they are susceptible to developing physical anomalies during processing and fiber-handling. Although these anomalies are believed to be benign, there are very few published re...

This research established the design guidelines for center embossed diaphragms for micro-diaphragm fiber type sensors. Following the guidelines, a center embossed diaphragm fiber optic sensor (CE-DFOS) based on Fabry–Perot interference was designed and fabricated with micro-electro-mechanical system (MEMS) technology. The CE-DFOS was experimentally verified to have the designed intrinsic freque...

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...

In this paper we introduce a PON mobile access network as a candidate to offer continuous multimedia IP communications to fast moving terminals in a micro-cellular environment. As an alternative to IP micro-mobility protocols we propose a PON access network with FA distributed over all access points connected to the same fiber. All ONU associated with the same FA are given the same IP address, ...
