We study the problem of recovering the sparsity pattern of block-sparse signals from noise-corrupted measurements. A simple, efficient recovery method, namely, a block-version of the orthogonal matching pursuit (OMP) method, is considered in this paper and its behavior for recovering the block-sparsity pattern is analyzed. We provide sufficient conditions under which the block-version of the OM...

A male child, 18 months old, with interrupted aortic arch, ventricular septal defect, postoperative complete heart block and an epicardial DDD pacemaker since the age of nine months, was admitted to our department because of episodes of syncope. At first the episodes were considered as epilepsy and the child was given antiepileptic drugs. Twenty-four-hour ambulatory electrocardiographic monitor...

a 25-year-old afghan male was presented to the emergency department with femoral shaft fracture following fall from the height. the patient was subjected to femoral nerve block and general anesthesia. first try for performing nerve block led to vascular puncture. therefore, the needle was removed and re-inserted 1 cm lateral to first puncture site and dex injected slowly with aspiration check a...

This paper is focused on possible designs and predicted performances of two proposed highenergy, high-luminosity electron-hadron colliders: eRHIC at Brookhaven National Laboratory (BNL, Upton, NY, USA) and LHeC at Organisation Européenne pour la Recherche Nucléaire (CERN, Geneve, Switzerland). The Relativistic Heavy Ion Collider (RHIC, BNL) and the Large Hadron Collider (LHC, CERN) are designed...

These electrocardiograms were taken on a 36 yearold man, with no known cardiac abnormality. The twelve-lead tracing, which shows sinus rhythm at rates between 53 and 60/min., has abnormal T waves in Vl V4. A s{rip, using lead V6, shows the interesting phenomenon of rate-dependent left bundle branch block (LBBB). Please. note in this strip that the first four sinus beats have normal QRS-T waves....

are reported. Second and third degree AV block occurred in I05 of i665 patients. Isoprenaline intravenously was used when clinically necessary and pacemaker only if isoprenaline failed to improve heart rate. Forty-four patients received no specific therapy, 47 received isoprenaline only, and I4 transvenous pacemaker therapy. Few complications of isoprenaline therapy were observed, which is ascr...

The geographical variability of the elemental concentration and isotopic composition of mercury and lead was evaluated in epiphytic lichens collected over a mesoscale area (Pyrenees-Atlantiques, Southwestern France). The sampling points have been selected according to different parameters in order to represent the main land use classification of the investigated territory (urban, industrial, ag...

Heterogeneity of cardiac electrical properties can lead to heart rhythm disorders. Numerical studies have shown that stimuli chosen to maximize dynamic heterogeneity terminate wave propagation. However, experimental investigations suggest that similar sequences induce fragmentation of the wave fronts, rather than complete wave block. In this paper we show that an insulating boundary in an other...

This paper introduces the extension of Walsh-Hadamard block codes in order to obtain complex valued block codes. These complex valued block codes lead to an improved spectral efficiency with additional lower error rate. Applied for low rate concatenated coding schemes required for CDMA uplink transmission, the gain in spectral efficiency due to the new codes can be used for strengthening other ...
