In this work we propose a novel approach to navigate users in GPS-denied environments with the help of sensors. The basic idea is to deploy wireless sensors over the field of interest and use the change of signal strength from multiple sensors to navigate users to the destination. To deal with RSS irregularity in a practical environment, an adaptive scheme is proposed to decide the scheme param...

The synchronization of a neuronal response to a given periodic stimulus is usually measured by Goldberg and Brown’s vector strength metric. This index does not take omitted spikes into account. This particular limitation has motivated the development of two new indices: the corrected vector strength index and the corrected phase variance index, both including a penalty factor linked to the firi...

Karoński, Luczak, and Thomason (2004) conjectured that, for any connected graph G on at least three vertices, there exists an edge weighting from {1, 2, 3} such that adjacent vertices receive different sums of incident edge weights. Bartnicki, Grytczuk, and Niwcyk (2009) made a stronger conjecture, that each edge’s weight may be chosen from an arbitrary list of size 3 rather than {1, 2, 3}. We ...

BACKGROUND Dysregulated respiratory control may play a role in the pathophysiology of panic disorder. This could be due to abnormalities in brain stem respiratory nuclei or to dysregulation at higher brain levels. Results from previous studies using the doxapram model of panic have yielded an unclear picture. A brief cognitive manipulation reduced doxapram-induced hyperventilation in patients, ...

Cutaneous melanocytic lesions, commonly known as moles, are mostly benign; however, some of them are malignant melanomas, the most fatal form of skin cancer. Because the survival rate of melanoma is inversely proportional to the thickness of the tumor, early detection is vital to the treatment process. Many dermatologists have advocated the development of computer-aided diagnosis systems for ea...

Davies, Ronnie M., George L. Gerstein, and Stuart N. Baker. Measurement of time-dependent changes in the irregularity of neural spiking. J Neurophysiol 96: 906–918, 2006. First published March 22, 2006; doi:10.1152/jn.01030.2005. Irregularity of firing in spike trains has been associated with coding processes and information transfer or alternatively treated as noise. Previous studies of irregu...

The aim of this study was to evaluate the relationship between the tongue volume and lower incisor irregularity, using cone-beam computed tomography (CBCT), and to identify the possible gender differences. CBCT images of 60 patients between 16 and 36 years of age were selected from 1400 sets of images in the database. Tomography was carried out using iCAT® (Imaging Sciences International, Hatfi...

A growing body of work on morphological irregularity has shown that the productivity of irregular morphological processes is sensitive to phonological context. However, these studies have focused almost exclusively on patterns of irregularity found in European languages. In this paper, I discuss a typologically different pattern of irregularity found in Lakhota: person marking appears as a pref...
