Publication date: 15 June 2016 *Source:*Materials & Design, Volume 100 Author(s): Jasim Ahamed, Mathew Joosten, Paul Callus, Michael R. Wisnom, Chun H. Wang Hybridisation of multiple materials is emerging as a key strategy to achieve high performance lightweight structures while keeping the cost low. Fundamental to creating strong and cost-effective hybrid composites is the ability to efficiently join dissimilar materials. Herein we present a novel co-curing ply-overlap joint technique for integrating dissimilar composite materials. Experimental studies are conducted to identify the...περισσότερα »

A matrix-free approach to efficient affine-linear image registration on CPU and GPU

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 33 δευτερόλεπτα
Abstract This paper presents a generic approach to highly efficient image registration in two and three dimensions. Both monomodal and multimodal registration problems are considered. We focus on the important class of affine-linear transformations in a derivative-based optimization framework. Our main contribution is an explicit formulation of the objective function gradient and Hessian approximation that allows for very efficient, parallel derivative calculation with virtually no memory requirements. The flexible parallelism of our concept allows for direct implementation on vari... περισσότερα »

IPAS: a design framework for analysis, synthesis and optimization of image processing applications for heterogenous computing architectures

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 33 δευτερόλεπτα
Abstract Recent trends in the image processing field have led to the use of more heterogeneous hardware architectures. The reason for this increase is that specialized cores, compared to standard CPUs, offer a more efficient way of achieving image processing applications. Specialized cores have less power, resource, and area consumption. On the other hand, designing such a heterogenous system with specialized cores is a challenging, error-prone and time-consuming task. Therefore, new frameworks are necessary for bringing an image processing application onto a given target platform ... περισσότερα »

Operating Room Delays: Meaningful Use in Electronic Health Record.

Perioperative areas are the most costly to operate and account for more than 40% of expenses. The high costs prompted one organization to analyze surgical delays through a retrospective review of their new electronic health record. Electronic health records have made it easier to access and aggregate clinical data; 2123 operating room cases were analyzed. Implementing a new electronic health record system is complex; inaccurate data and poor implementation can introduce new problems. Validating the electronic health record development processes determines the ease of use and the use...περισσότερα »

Compressive multi-spectral imaging using self-correlations of images based on hierarchical joint sparsity models

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 33 δευτερόλεπτα
Abstract We propose a novel multi-spectral imaging method based on compressive sensing (CS). In CS theory, the enhancement of signal sparsity is important for accurate signal reconstruction. The main novelty of the proposed method is the employment of a self-correlation of an image, that is a local intensity similarity and multi-spectral correlation, to enhance the sparsity of the multi-spectral image to be recovered. Local intensity similarity, which is based on the concept that spatial changes in intensity are likely to be similar within local regions, contributes to sparsity en... περισσότερα »

Abstract A major challenge in next-generation industrial applications is to improve numerical analysis by quantifying uncertainties in predictions. In this work we present a formulation of a fully nonlinear and dispersive potential flow water wave model with random inputs for the probabilistic description of the evolution of waves.

Socially induced serotonergic fluctuations in the male auditory midbrain correlate with female behavior during courtship

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
Cues from social partners trigger the activation of socially responsive neuromodulatory systems, priming brain regions including sensory systems to process these cues appropriately. The fidelity with which neuromodulators reflect the qualities of ongoing social interactions in sensory regions is unclear. We addressed this issue by using voltammetry to monitor serotonergic fluctuations in an auditory midbrain nucleus, the inferior colliculus (IC), of male mice (*Mus musculus*) paired with females, and by concurrently measuring behaviors of both social partners. Serotonergic activit... περισσότερα »

Tactile texture signals in primate primary somatosensory cortex and their relation to subjective roughness intensity

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
This study investigated the hypothesis that a simple intensive code, based on mean firing rate, could explain the cortical representation of subjective roughness intensity and its invariance with scanning speed. We examined the sensitivity of neurons in the cutaneous, finger representation of primary somatosensory cortex (S1) to a wide range of textures [1 mm high, raised-dot surfaces; spatial periods (SPs), 1.5–8.5 mm], scanned under the digit tips at different speeds (40–115 mm/s). Since subjective roughness estimates show a monotonic increase over this range and are independent...περισσότερα »

Sensory-driven and spontaneous gamma oscillations engage distinct cortical circuitry

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
Gamma oscillations are a robust component of sensory responses but are also part of the background spontaneous activity of the brain. To determine whether the properties of gamma oscillations in cortex are specific to their mechanism of generation, we compared in mouse visual cortex in vivo the laminar geometry and single-neuron rhythmicity of oscillations produced during sensory representation with those occurring spontaneously in the absence of stimulation. In mouse visual cortex under anesthesia (isoflurane and xylazine), visual stimulation triggered oscillations mainly between ... περισσότερα »

KV1 channels identified in rodent myelinated axons, linked to Cx29 in innermost myelin: support for electrically active myelin in mammalian saltatory conduction

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
Saltatory conduction in mammalian myelinated axons was thought to be well understood before recent discoveries revealed unexpected subcellular distributions and molecular identities of the K+-conductance pathways that provide for rapid axonal repolarization. In this study, we visualize, identify, localize, quantify, and ultrastructurally characterize axonal KV 1.1/KV1.2 channels in sciatic nerves of rodents. With the use of light microscopic immunocytochemistry and freeze-fracture replica immunogold labeling electron microscopy, KV1.1/KV1.2 channels are localized to three anatomica... περισσότερα »

Selection of head and whisker coordination strategies during goal-oriented active touch

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
In the rodent whisker system, a key model for neural processing and behavioral choices during active sensing, whisker motion is increasingly recognized as only part of a broader motor repertoire employed by rodents during active touch. In particular, recent studies suggest whisker and head motions are tightly coordinated. However, conditions governing the selection and temporal organization of such coordinated sensing strategies remain poorly understood. We videographically reconstructed head and whisker motions of freely moving mice searching for a randomly located rewarded apert...περισσότερα »

Temporal accuracy of human cortico-cortical interactions

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 50 δευτερόλεπτα
The precision in space and time of interactions among multiple cortical sites was evaluated by examining repeating precise spatiotemporal patterns of instances in which cortical currents showed brief amplitude undulations. The amplitudes of the cortical current dipoles were estimated by applying a variant of synthetic aperture magnetometry to magnetoencephalographic (MEG) recordings of subjects tapping to metric auditory rhythms of drum beats. Brief amplitude undulations were detected in the currents by template matching at a rate of 2–3 per second. Their timing was treated as poin... περισσότερα »
