The dentate gyrus (DG) and the olfactory bulb (OB) are two regions of the adult brain in which new neurons are integrated daily in the existing networks. It is clearly established that these newborn neurons are implicated in specific functions sustained by these regions and that different factors can influence neurogenesis in both structures. Among these, life events, particularly occurring dur...

OBJECTIVES/HYPOTHESIS Clinically, inflammatory polyps are found in the middle turbinate (MT) in patients with chronic rhinosinusitis (CRS) but not in the inferior turbinate (IT). The purpose of this study was to investigate differences in protein expression between IT and MT tissue in patients with CRS. STUDY DESIGN Prospective cohort. METHODS Pathologic specimens obtained from patients wit...

Acute unilateral vestibulopathy, or vestibular neuritis, is the second most common cause of vertigo. To quantify the involvement of the different semicircular canal (SCC) afferents in this disease, we studied the three-dimensional (3D) properties of the vestibuloocular reflex (VOR) in 16 patients 3-10 days after onset of symptoms. Using 3D magnetic search coil eye movement recordings, we measur...

This paper presents several techniques for adding fault-tolerance t o distributed memory parallel computers. More formally, given a target graph with n nodes, we create a fault-tolerant graph with n + k nodes such that given any set of k or fewer faulty nodes, the remaining graph is guaranteed to contain the target graph as a fault-free subgraph. As a result, any algorithm designed for the targ...

The research investigates the influence of an effective maintenance system on the efficient performance of any industrial system. The core concept of the research explains that the simultaneous focus on the spares inventory subsystem as well as on the preventive maintenance subsystem must be considered when developing a quality maintenance programme. Considering and developing such aspects sepa...

Prior studies on performance-based contracting (PBC) for after-sales services have highlighted its advantages over traditional resource-based contracting (RBC), when products are established and their reliability is known to all parties. We develop a game theoretic model to investigate how these insights are affected when the vendor is privately informed about the reliability of a newly develop...

In this paper, a new model has been presented to determine the number of spare transformers and their locations for distribution stations. The number of spare transformers must be so that they need minimum investment. Furthermore, they must be sufficient for replacing with transformers that have been damaged. For this reason, in this paper a new purpose function has been presented to maximize p...

The k-out-of-N structure is a popular type of redundancy in fault-tolerant systems with wide applications in computer and communication systems, and power transmission and distribution systems, among others, during the past several decades. In this paper, our interest is in such a reliability system with identical, repairable components having exponential life times, in which at least k out of ...
