A coplanar waveguide (CPW) fed flexible interconnected 4-port MIMO antenna is proposed for UWB, X, and Ku band applications having a size 0.67 lambda x 0.81 lambda x 0.0028 lambda (at 3.58 GHz). The antenna parameters are ...

Innovations in the fields of virtual reality (VR) and augmented reality (AR) and the availability and usability improvements seen in recent years in these technologies have opened new possibilities in the field of foreign ...

Nesting habits of the digger wasp Lindenius albilabris (Fabricius, 1793) at two localities in Poland were studied. The female hunts nymphs or adults of plant bugs Lygus rugulipennis Poppius, 1911 and L. pratensis (Linnaeus, ...

The archipelago of Svalbard is a good example of an Arctic locale undergoing rapid changes on multiple levels. This contribution is a joint effort of three anthropologists with up-to-date ethnographic data from Svalbard ...

Continuous monitoring of the intracranial pressure (ICP) is essential in neurocritical care. There are a variety of ICP monitoring systems currently available, with the intraventricular fluid filled catheter transducer ...

Many studies have demonstrated that exposure to simulated natural scenes has positive effects on emotions and reduces stress. In the present study, we investigated emotional facial expressions while viewing images of various ...

Microwave sensors are principally sensitive to effective permittivity, and hence not selective to a specific material under test (MUT). In this work, a highly compact microwave planar sensor based on zeroth-order resonance ...
