explore the earliest levels of striate cortical processing: the first stage, where orientation sensitivity emerges, and the second stage, where stimulus selectivity is further refined. The approach is wholecell recording from cat in vivo. Neurons in the lateral geniculate nucleus of the thalamus have circular receptive fields whose subregions, center and surround are concentrically arranged and...

In this paper we experimentally investigate how the allocation of inventory risk in a two-stage supply chain affects channel efficiency. We first evaluate two common wholesale price contracts that differ in which party incurs the risk associated with unsold inventory; a push contract in which the retailer incurs the risk, and a pull contract in which the supplier incurs the risk. Our experiment...

This paper investigates the pricing and production game in a decentralized assembly system that consists of one assembler and two independent suppliers. One supplier is able to exert the push contract on the assembler so as to transfer all his inventory risk, while the other supplier has to accept the pull contract from the assembler and consequently bears the overstock risk. Under this hybrid ...

In this paper, a nonlinear theory applicable to the design of nanotube based devices is presented. The role of finite kinematics for a doubly clamped nanotube device is investigated. In particular, we analyze the continuous deformation and instability (pull in) of a clamped-clamped nanotube suspended over an electrode from which a potential differential is imposed. The transformation of an appl...

Patterned surfaces have proven to be a valuable design enhance adhesion, increasing hysteresis and the detachment stress at pull-off. To obtain high adhesive performance, soft materials are commonly, used, which easily conform countersurface, such as polymers elastomers. Such viscoelastic; i.e., they show rate-dependent properties. Here, of two half spaces is studied, one being flat other havin...
