We study equations of a non-gauge vector field in a spherically symmetric static metric. The constant vector field with a scale arrangement of components: the temporal component about the Planck mass m Pl and the radial component about M suppressed with respect to the Planck mass, serves as a source of metric reproducing flat rotation curves in dark halos of spiral galaxies, so that the velocit...

Michelle M. Lusardi, PhD, PT Pamela K. Levangie, DSc, PT Beverly D. Fein, MS, PT Given the complexity and the pace of today's health care environment, educators of health professionals are increasingly challenged to insure that graduates of entry-level programs have requisite knowledge, skills, and attitudes for competent patient care, as well as the capability of adapting to change, generating...

In a previous paper it was established that there are at least 27 non-isomorphic strongly regular (40, 12, 2, 4) graphs. Using a different and more efficient method we have re-investigated these graphs and have now been able to determine them all, and so complete the classification. We have discovered that there are precisely 28 non-isomorphic (40, 12, 2, 4) strongly regular graphs. The one tha...

The alkenone-pCO2 methodology has been used to reconstruct the partial pressure of ancient atmospheric carbon dioxide (pCO2) for the past 45 million years of Earth's history (Middle Eocene to Pleistocene epochs). The present long-term CO2 record is a composite of data from multiple ocean localities that express a wide range of oceanographic and algal growth conditions that potentially bias CO2 ...

Spatiotemporally organized waves are among the most ubiquitous activity patterns in the brain. Recent advances in electrophysiology, imaging, and other technologies allow experimentalists to observe these activity patterns simultaneously in the responses of many individual neurons and in the ensemble response of the neural circuit, both in vivo (the whole animal/subject) and in vitro (e.g., cul...

Even thick sequences of sediments in marine depositional basins contain only limited segments of the record of chlorophyll diagenesis. Extracts from Pleistocene deep-sea sediments (Baker and Smith, 1973a) yielded extensive information concerning early chlorin transformations. Investigations of marine sediments of Pliocene and Miocene age resulted in the first reports of free base porphyrins occ...

Background and Aims: An effective marker search in glioblastoma is precious in controlling and detecting the progression and monitoring of patients with glioblastoma. In this regard, the present study aimed to evaluate the diagnostic and prognostic role of glial fibrillary acidic protein (GFAP), insulin-like growth factor-binding protein -2 (IGFBP-2), and chitinase-3-like protein -1 (YKL-40) ti...

The goal of this study was to enhance an existing automated teller machine (ATM) human–machine interface in order to accommodate the needs of older adults. Older adults were involved in the design and field test of the modified ATM prototype. The design of the user interface and functionality took the cognitive and physical abilities of older adults into account. The modified ATM system include...

Neurons have been classified by their firing properties and by their differing dendritic characteristics, architectures, and biophysical properties, suggesting the existence of design principles and computational goals. From a classical viewpoint, dendrites provide the pathways that funnel the many subthreshold postsynaptic potentials (PSPs) toward the soma, where the propagated–summated result...
