Using heterochromatic flicker photometry, we have measured the corneal spectral sensitivities of the X-chromosome-linked photopigments in 40 dichromats, 37 of whom have a single opsin gene in their tandem array. The photopigments encoded by their genes include: the alanine variant of the normal middle-wavelength sensitive photopigment, M(A180); the alanine and serine variants of the normal long...

The paper deals with wavelength routing in WDM (wavelength division multiplexing) optical networks. Wavelengths must be assigned to connection requests which are represented as directed paths, and it is required that paths receive different wavelengths if they share a directed link. The goal is to minimize the number of wavelengths used. Mihail et al. [10] conjectured that there is a solution f...

We first study the temporal Wilson loop in the finite-temperature non-commutative dipole field theory from the string/gauge correspondence. The associated dual supergravity background is constructed from the near-horizon geometry of near-extremal D-branes, after applying T-duality and smeared twist. We investigate the string configuration therein and find that while the temperature produces a m...

Introduction: High sound, is an occupational and environmental hazard common. Hospitals as medical and health care setting are affected by noise sources. Therefore, the aim of this study is to investigate the noise pollution in Shiraz hospitals. Methods: A cross-sectional study in different parts and the area around the 8 educational and non-educational hospitals in Shiraz was performed. For...

The nature of the dark energy (DE) is one of the most outstanding problems of physical sciences today. Numerous and often ingenious attempts have been made to explain it, with multiple new papers appearing daily, yet no model proposed so far has gained a general acceptance. Modern approaches to the problem date from the pioneering papers by Zel’dovich [1], who was first to recognize the fundame...

Winkler and Zhang introduced the FIBER MINIMIZATION problem in [3]. They showed that the problem is NP-complete but left the question of approximation algorithms open. We give a simple 2-approximation algorithm for this problem. We also show how ideas from the Dynamic Storage Allocation algorithm of Buchsbaum et al [1] can be used to give an approximation ratio arbitrarily close to 1 provided t...

The idea that we live in a Universe undergoing a period of acceleration is a new, yet strongly held, notion in cosmology. As this can, potentially, be explained with a modification to General Relativity we look at current cosmological data with the purpose of testing aspects of gravity. Firstly we constrain a phenomenological model (mDGP) motivated by a possible extra dimension. This is charact...

This paper proves that the existence of a feasible schedule for set dependent tasks unit execution times with release dates and deadlines on limited number processors is fixed-parameter tractable problem. The parameter considered pathwidth interval graph associated time windows tasks. A algorithm based dynamic programming approach developed proved to solve this decision Fixed-parameter algorith...

This paper considers the problem of scheduling n jobs on a single machine. A fixed processing time and an execution interval are associated with each job. Preemption is not allowed. On the basis of analytical and numerical dominance conditions, an efficient integer linear programming formulation is proposed for this problem, aiming at minimizing the maximum lateness (Lmax). Experiments have bee...

Introduction Despite their basal place in vertebrate evolution, little quantitative data is available on shark (chondrichthyan) brain organization & its implications for nervous system adaptations [1,2], including our own. The cerebellum appeared at the onset of the chondrichthyan radiation, with extreme variations in cerebellar morphology during subsequent evolution, highlighting their role as...
