The history of life is fi lled with examples of one species diverging into several, even thousands, each with unique traits geared to the demands of its ecological niche. In the textbook case of adaptive radiation, an ancestral fi nch species landed on the Galapagos Islands just a few million years ago, and evolved into 13 new species with specialized beaks adapted to exploiting the various see...

The purpose of this work is to implement a novel active radar system for single access point two-dimensional localization based on 802.11 wireless local-area networks (WLAN). employes the Fine Time Measurement (FTM) Round Trip (RTT) as specified in 2016 update WIFI Standard calculate ranging distance and acquires two channels Received Signal Strength Indicator (RSSI) estimate azimuthal angle. I...

I review the current constraints on the nature of the hotspots of FRII radio sources, and the physical conditions that obtain in them. New Chandra observations suggest that the majority of X-ray detections of hotspots are due to inverse-Compton processes, with magnetic field strengths close to the standard equipartition/minimumenergy values. However, a few broad-line objects have X-ray emission...

In this paper, we concern the generation of attractive net motion with respect to location external wave source for active spherical carriers. Here recall that exerted acoustic radiation force in an field resulting from incident wave, a scattered and radiated carrier, can be positive, negative, or zero based on object field. Thus, general case, sustainable pulling is not guaranteed. work, by co...

Mucopolysaccharidoses (MPSs) are a group of rare genetic disorders within the larger family of lysosomal diseases. MPSs disorders are caused by a defi ciency in the activity of a specifi c lysosomal enzyme required for the degradation of glycosaminoglycans (GAGs). MPS type II, also called Hunter syndrome consists in a defi ciency of an enzyme, iduronate-2-sulphatase. We present a rare case of H...

pulse pressure variation (PPV) is not an accurate predictor of fl uid responsiveness in subjects with pulmonary hypertension [1,2]. We agree that PPV and stroke volume variation (SVV) may not work in patients with right ventricular (RV) failure. Indeed, when PPV and SVV are related to an inspiratory increase in RV afterload (and not to a decrease in RV preload), they cannot serve as indicators ...
