Haptic interfaces are devices that allow human-machine interaction through force and touch. Combined haptic and visual interfaces have been around for decades. Yet, despite an enormous increase in research activity in the last few years, the science of haptics is still a technology in its infancy. The majority of commercially available haptic devices operate based on a principle of point intera...

Regarding our article on the association of androgen deprivation therapy (ADT) with increased Alzheimer’s disease risk, Bowen et al, Froehner and Wirth, Leow et al, and Brady et al highlight a number of significant considerations that will prove important in the design of future studies that investigate the association of ADT and Alzheimer’s disease. We agree with Bowen et al and Leow et al tha...

Defects in myosin VIIa are responsible for Usher Syndrome 1B (Weil et al., 1995). Human Usher syndrome (USH), named after the British ophthalmologist Charles Usher (Usher, 1914), is the most common hereditary form of combined blindand deafness (≈ 50 % of cases in the developed countries). USH designates a group of clinically and genetically heterogeneous disorders with hearing loss and retiniti...

It has been well-known that tight relationship exists between chaos and cryptography [Brown & Chua, 1996]. Many fundamental characteristics of chaos, such as ergodicity, mixing property and sensitivity to initial conditions/control parameters [Hao, 1993], can be connected with some cryptographic properties of good ciphers, such as confusion/diffusion, balance and avalanche property [Schneier, 1...

We test the correlation found by Reichart et al. (2001) between time variability and peak luminosity of Gamma-Ray Bursts (GRBs). Recently Guidorzi et al. (2005) found that this still holds for a sample of 32 GRBs with spectroscopic redshift, although with a larger scatter than that originally found by Reichart et al. (2001). However Guidorzi et al. (2005) also found that a power law does not pr...

Faith et al. (2003) strongly criticize our paper (Posadas et al. 2001). Their criticisms are based on what they consider our “ill definitions” and “erroneous applications” of the words complementarity, endemism, and biodiversity. The objectives of our reply to Faith et al. are to demonstrate that their criticisms do not satisfy epistemological and methodological tenets and to compare some aspec...

The differentiation of a proliferating neural progenitor into a postmitotic neuronal cell is a critical transition during mammalian neural development. During this time period, extensive cell lineage commitments are formed based on signals from dorsoventral and anteroposterior signaling centers (Altmann and Brivanlou, 2001; Briscoe et al., 2000; Chiang et al., 1996; Lee et al., 2000). These sig...

The diagnosis of ND begins with its characterization as either a physiological or pathological condition (Simmons et al., 2003). Physiological discharge, often a manifestation of breast manipulation, is usually bilateral, is white or green, and emanates from many ducts (Simmons et al., 2003). Possible causes of persistent physiological discharge include oral contraceptives, antihypertensives, t...

The aim of this study was to determine the effect of knowledge management capabilities and information technology capabilities on innovative performance with the mediating role of organizational entrepreneurship, organizational learning and competitive advantage. The research method is descriptive-survey. The statistical population consists of all employees of Shimifar Iran Company, and 137 peo...
