Hyperspectral images consist of large number of spectral bands but many of which contain redundant information. Therefore, band selection has been a common practice to reduce the dimensionality of the data space for cutting down the computational cost and alleviating from the Hughes phenomenon. This paper presents a new technique for band selection where a(More)
We consider the approximate sparse recovery problem in multi-hop Wireless Sensor Networks (WSNs) using Compressed Sensing/Compressive Sampling (CS). The goal is to recover the n-dimensional data values by querying only m ≪ n sensors based on some linear projection of sensor readings. To solve this problem, a distributed compressive sparse sampling(More)
OBJECTIVE Neoadjuvant therapy has been extensively analyzed in studies addressing the risk factors of bronchopleural fistula, but their results vary hugely. Therefore, we conducted this meta-analysis to determine the association between neoadjuvant therapy and risk of bronchopleural fistula in patients undergoing lung cancer surgery. METHODS We searched(More)
Postoperative atrial arrhythmia is the most common dysrhythmia seen after lung transplantation. However, risk factors for postoperative atrial arrhythmias and their impact on outcomes were inconsistent. The aim of our study was to conduct a meta-analysis to analyse risk factors of postoperative atrial arrhythmias and the impact of postoperative atrial(More)
In this paper, we present a pervasive and unobtrusive system for sensing human emotions, which are inferred based on the recording, processing, and analysis of the Galvanic Skin Response (GSR) signal from human bodies. Being different from traditional multi modal emotion sensing systems, our proposed system recognizes human emotions with the single(More)
Latest evidence indicates that Nestin expression may be associated with the high malignancy and poor prognosis of non-small cell lung cancer (NSCLC), but a relevant consensus has not been reached until now. Therefore, we conducted this meta-analysis to evaluate the clinicopathological and prognostic significance of Nestin expression in patients with NSCLC.(More)
OBJECTIVES Residual disease at the bronchial stump (RDBS) is regarded as an important factor possibly resulting in bronchopleural fistula (BPF) after lung cancer surgery, but this has not been confirmed. We conducted this meta-analysis to evaluate the effects of RDBS on BPF formation in patients undergoing lung cancer surgery. METHODS PubMed and EMBASE(More)
This paper focuses on surveillance video processing using Compressed Sensing (CS). The CS measurements are used for recovery of the video frame into a low-rank background component and sparse component that corresponds to the moving object. The spatial and temporal low-rank features of the video frame, e.g., the nonlocal similar patches within the single(More)
This paper presents an unobtrusive, energy-efficient approach to human activity sensing through the intelligent scheduling of built-in sensors on mobile phones and light-weight compressed sensing. We refer to this framework as pattern-based compressed phone sensing (P-CPS) where two challenging issues are studied, the energy drainage issue due to continuous(More)
Summary The paradoxical benefit of obesity, the 'obesity paradox', has been recently identified in surgical populations. Our goal was to evaluate by a systematic review with meta-analysis the prognostic role of body mass index (BMI) and to identify whether the 'obesity paradox' exists in lung cancer surgery. Comprehensive literature retrieval was conducted(More)
