PURPOSE This study examined the effects of chin-down swallowing on laryngeal vestibule closure. It also investigated the technique's rehabilitative impact, by assessing the stability of effects across multiple trials and aftereffects in neutral swallows on cessation of the technique. METHOD Duration of laryngeal vestibule closure (dLVC) was measured with videofluoroscopy in 16 healthy partici...

While a significant amount of work has been carried out on digital receivers to support flexible and adaptive high data rate processing for multiple systems, small interest has been shown on the RF part and especially the advantages of using a broadband RF front end. This paper presents a challenge raised in the design of a single flexible multimode and multiband RF receiver. It proposes a new ...

In the last chapter, we saw that greedy algorithms are efficient solutions to certain optimization problems. However, there are optimization problems for which no greedy algorithm exists. In this chapter, we will examine a more general technique, known as dynamic programming, for solving optimization problems. Dynamic programming is a technique of implementing a top-down solution using bottom-u...

The present investigation deals with the bulk arrival M/G/1 retrial queue with impatient customers and modified vacation policy. The incoming customers join the virtual pool of customers called orbit if they find the server being busy, on vacation or in broken down state otherwise the service of the customer at the head of the batch is started by the server. The service is provided in k</em...

The performance of underwater acoustic communication is significantly affected by multipath propagation and Doppler spread. In this paper, we propose a new technique called overlapped chirp spread carrier (OCSC) modifying the existing sweep (SSC) technique, which robust in environment. Our proposed OCSC uses repeated wave combining up-chirp down-chirp signals estimates corrects shift frequency ...

Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human tumor cell lines. Materials and Met...
