We present an end-to-end image-processing pipeline that is accelerated using coupled spin-torque oscillator (STO) arrays for its key computational kernels. Coupled oscillator arrays are used throughout the pipeline, including the computation of spectral and spatial transforms in the saliency stages and convolution in the CNN-based classifiers in the back end. We present results for two types of oscillator models, a generic, parameterized, model that captures variations in coupling asymmetry, locking range, and noise, and a hardware calibrated spice model of a coupled STO array with data curve fitted to a closed-form C++ model. The pipeline was run over three benchmark datasets, the Neovision2 Tower and Helicopter datasets[1] and the DARPA Vivid dataset[2]. We show the sensitivity of the output to parameter variations in the generic model and show equivalent performance for the STO model. © VDE VERLAG GMBH.

Concerns for the environment, health and safety are of major importance and have been attracting considerable attention around the globe due to the new environmental challenges that are threatening our planet. In this paper, we propose to enhance the fault detection of an air quality monitoring network (AQMN) by using wavelet principal component analysis (WPCA)-based on generalized likelihood ratio test (GLRT). The presence of measurement noise in the data and model uncertainties degrade the quality of fault detection (FD) techniques by increasing the rate of false alarms. Therefore, the objective of this paper is to enhance the FD of an AQMN by using wavelet representation of data, which is a powerful feature extraction tool to remove the noises from the data. Wavelet data representation has been used to enhance the FD abilities of principal component analysis. Therefore, in the current work, we propose to use WPCA-based on GLRT technique for FD. The fault detection performances of the WPCA-based GLRT technique are shown using air quality monitoring network (AQMN). The results showed the detection efficiency of developed WPCA-based GLRT technique, when compared to classical PCA and WPCA techniques.

As crude oil is becoming even more important commodity in the world economy, the crude oil prices fluctuation has affected both many businesses' decision based on the crude oil prices and consumers by price inflation on consumer goods. Accordingly, the crude oil prices forecasting has continuously been interested by a lot of researchers. Text data mining from news articles is one of the widely used methods to predict the crude oil price variation caused by irregular events. Nevertheless, the main issues in text mining originate from the particularities of natural language and a great number of noisy data preventing some techniques from employing efficiently [1]. In this research, the expert-based text mining was proposed in order to screen out the noisy data before the following steps of text mining started and to cope with the concern of natural language in text mining methods. Next, the fuzzy Delphi method was then combined in order to achieve fuzzy weighted ratings for different corresponding factors extracted from the news articles. As a result, Expert-Based Text Mining with Fuzzy Delphi Method was shown to outperform the original in term the ability to predict the historical crude oil price data.

Semiconductor microcavity polaritons, formed via strong exciton-photon coupling, provide a quantum many-body system on a chip, featuring rich physics phenomena for better photonic technology. However, conventional polariton cavities are bulky, difficult to integrate, and inflexible for mode control, especially for room temperature materials. Here we demonstrate sub-wavelength thick one-dimensional photonic crystals (PCs) as a designable, compact and practical platform for strong coupling with atomically thin van der Waals Crystals (vdWCs). Polariton dispersions and mode anti-crossings are measured up to room temperature. Non-radiative decay to dark excitons was suppressed due to polariton enhancement of the radiative decay. Unusual features, including highly anisotropic dispersions and adjustable Fano resonances in reflectance, may facilitate high temperature polariton condensation in variable dimensions. Combining slab PCs and vdWCs in the strong coupling regime allows unprecedented engineering flexibility for exploring novel polariton phenomena and device concepts. Copyright © 2017, The Authors.

Transcriptomics, regional cerebral blood flow (rCBF), and a spatial motor virtual reality task were integrated using mediation analysis in a novel demonstration of "imaging omics". Data collected in NCAA Division I football athletes cleared for play before in-season training showed significant relationships in a) elevated levels of miR-30d and miR-92a to elevated putamen rCBF, (b) elevated putamen rCBF to compromised balance scores, and (c) compromised balance scores to elevated miRNA levels. rCBF acted as a mediator variable (minimum 70% mediation, significant Sobel's test) between abnormal miRNA levels and compromised balance scores. Given the involvement of these miRNAs in inflammation and immune function, and that vascular perfusion is a component of the inflammatory response, these findings support a chronic inflammatory model of repetitive head acceleration events (HAEs). rCBF, a systems biology measure, was necessary for miRNA to affect behavior. These results suggest miRNA as a potential diagnostic biomarker for repetitive HAEs. Copyright © 2019, The Authors. All rights reserved.

Venoms are a rich source for the discovery of molecules with biotechnological applications, but their analysis is challenging even for state-of-the-art proteomics. Here we report on a large-scale proteomic assessment of the venom of Loxosceles intermedia, the so-called brown spider. Venom was extracted from 200 spiders and fractioned into two aliquots relative to a 10 kDa cutoff mass. Each of these was further fractioned and digested with trypsin (4 h), trypsin (18 h), pepsin (18 h), and chymotrypsin (18 h), then analyzed by MudPIT on an LTQ-Orbitrap XL ETD mass spectrometer fragmenting precursors by CID, HCD, and ETD. Aliquots of undigested samples were also analyzed. Our experimental design allowed us to apply spectral networks, thus enabling us to obtain meta-contig assemblies, and consequently de novo sequencing of practically complete proteins, culminating in a deep proteome assessment of the venom. Data are available via ProteomeXchange, with identifier PXD005523.

Information involves in design process, and in fact designing is an activity of converting data, information and knowledge into a map and guidance of creating an artifact. Unfortunately, the existing instruments that supporting designers' information search do not fit to them in term of their naturally way of doing so. This research is aimed at developing an information search application purposely for designers especially in the creative design process. And this paper will focus on the development and implementation a so called Search Result Side Note application. © 2016 IEEE.
