Grewal, Michelle, Janis Cuevas, Gautam Chaudhuri, and Lauren Nathan. Effects of calcitonin gene-related peptide on vascular resistance in rats: role of sex steroids. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H2063–H2068, 1999.—It has been demonstrated in reflex-intact animals that the sensitivity to calcitonin gene-related peptide (CGRP) is increased during pregnancy and that this action i...

As the fourth fundamental circuit element, memristor may execute computations while storing data. Fracmemristor takes advantage of fractional calculate’s long-term memory, non-locality, weak singularity, and memristor’s storage–computational integration. Since physical structure fracmemristor is similar to topology ant transfer probability flow in ACO, we propose fractional-order memristive col...

This article describes a hybrid approach to machine translation (MT) that is inspired by the rule-based, statistical, example-based, and other hybrid machine translation approaches currently used or described in academic literature. It describes how the approach was implemented for language pairs using only limited monolingual resources and hardly any parallel resources (the METIS-II system), a...

The population-based ant colony optimization algorithm (PACO) uses a very different pheromone update when compared to other ACO algorithms. In this work, we study P-ACO’s behavior for solving the traveling salesman problem (TSP) and the quadratic assignment problem (QAP). In particular, we investigate the impact of a local search on P-ACO parameters and performance. The results clearly show tha...

In 1905, HALDANE and PR.rnsn.EY [1] demonstrated the dramatic sensitivity of human ventilation to small increases in arterial carbon dioxide tension (Paco 2 ), a response now known to be mediated by the intracranial chemoreceptors, with an oxygen-dependent contribution from the peripheral chemoreceptors. Since that time, the response of minute or alveolar ventilation to increases in Paco2, indu...

BACKGROUND In many studies of patients with muscle weakness, chronic hypercapnia has appeared to be out of proportion to the severity of muscle disease, indicating that factors other than muscle weakness are involved in CO(2) retention. In patients with COPD, the unbalanced inspiratory muscle loading-to-strength ratio is thought to trigger the signal for the integrated response that leads to ra...

OBJECTIVE Arterial oxygen saturation (Sao(2)) and arterial carbon dioxide partial pressure (Paco(2)) are 2 of the most important respiratory parameters in the treatment of critically ill neonates. Noninvasive monitoring of these parameters is desirable for continuous estimating of the respiratory status and reducing blood loss because of repeated blood gas analyses. Transcutaneous measurement o...

Cerebral Microangiography After Hypocarbia and Hypercarbia • Ischemic infarction was obtained in the basal ganglia and internal capsule of the Rhesus monkey by clipping the middle cerebral artery at its origin through a transorbital approach. The postmortem microvasculature was demonstrated using microtized barium (Micropaque) and soft x-ray technology. The effects on this microvasculature indu...
