In this article we give a review of regression-based Monte Carlo methods for pricing American options. The methods require in a first step that the generally in continuous time formulated pricing problem is approximated by a problem in discrete time, i.e., the number of exercising times of the considered option is assumed to be finite. Then the problem can be formulated as an optimal stopping p...

Mobile ad hoc network (MANET) is composed of mobile nodes, which do not have any fixed and wired communication infrastructure. This paper discusses a source based hybrid routing protocol called ‘Hybrid Hop count based Multiple Quality of Service (QoS) constraints Routing Protocol with Mobility Prediction (HMQRPMP) for MANET’. It deals with QoS parameters of wireless links namely delay, delay-ji...

A biosimilar product needs to demonstrate biosimilarity to the originator reference product, and the quality profile of the latter should be monitored throughout the period of the biosimilar's development to match the quality attributes of the 2 products that relate to efficacy and safety. For the development of a biosimilar version of trastuzumab, the reference product, Herceptin®, was extensi...

The evolution of contact lens technology and clinical practice over the past three decades has been remarkable, with dramatic improvements in material biocompatibility, better lens designs and care systems, and more flexible and convenient modalities of wear. However, our approach to the aftercare examination has remained conservative, with the general modus operandi having not fully evolved fr...

Background: Bread, a basic need for the survival of human beings, is highly perishable, has short shelf-life, and loses its quality potency after date expiry. This leads to considerable amount bread waste loss in economy. study explores analyses most common causes wastage supply chain proposes key strategies mitigation bread-producing industries context Indian bakeries.

Background: Ready-To-Eat (RTE) foods include any edible food that is commonly consumed raw. This study aimed at evaluation of microbial ecology of retail RTE escarole and red chicory sold in Palermo city, Italy. Methods: A total of 32 mono-varietal RTE samples, including escarole (n=16) and red chicory (n=16) samples were obtained from Palermo, Italy. Both RTE vegetables at expiry date were an...

The behavior of the optimal exercise price American puts near expiry has been well studied under Black–Scholes model as a result series publications. However, stochastic volatility model, such Heston not reported at all. Adopting method matched asymptotic expansions, this paper addresses put options on dividend-paying underlying with expiry. Through our analyses, we are able to show that option...
