We report the theoretical prediction of a class spintronic materials, namely, bipolar magnetic semiconductors (BMSs), also supported by our experimental data. BMSs possess unique band structure with unequal gaps for spin-up and spin-down channels thus are useful tunable spin-transport-based applications such as spin filters. The valence conduction in approach Fermi level through opposite hence ...

In this paper, we study the effects of the variations of the propagation delay over large-scale antenna-arrays used in massive multiple-input multiple-output (MIMO) wideband communication systems on the statistical properties of the channel. Due to its simplicity and popularity, the Elliptical geometry-based stochastic channel model (GBSM) is employed to demonstrate new non-stationary propertie...

Now that the conjectures of Leedham-Green and Newman have been proved, we probe deeper into the classification of p-groups using coclass. We determine the pro-2-groups of coclass at most 3 and use these to classify the 2-groups of coclass at most 3 into families. Using extensive computational evidence, we make some detailed conjectures about the structure of these families. We also conjecture t...

Green innovation has been deemed a key corporate capability to deal with environmental issues. The usage of advanced manufacturing technologies (AMT) provides important resources and knowledge for firms’ green innovation. Drawing on a resources-based approach, this study contributes to the existing literature by examining how the adoption of specific types of AMT (process, design, and planning)...

Introduction. To date, the use of unmanned aerial vehicles (UAVs) in Ukraine for agricultural lands treatment is a new promising technology that requires detailed study and development approaches to risk assessment hygienic regulation. Development method will allow measuring content diamond blue FCF sorption material (filter paper) relevant. The aim – determining synthetic dye by high-performan...

We give a proof of Green’s theorem which captures the underlying intuition and which relies only on the mean value theorems for derivatives and integrals and on the change of variables theorem for double integrals.

|An algorithm is presented for tracking a landing aircraft using fusion of two diierent passive sensors, a laser range nder (LRF) and a forward-looking infrared (FLIR) camera. The main feature of this algorithm is its ability to identify and compensate for an exhaust plume disturbance. The algorithm is based on the extended Kalman lter (EKF) and the ltering conndence function (FCF) which introd...

Methods Fifteen patients with midfoot arthritis aged between 20 and 60 years participated in the study. Foot function index (FFI) was assessed to evaluate pain before and after the walking activity. Lower leg muscle activity, GRF and gait cycle time during walking were measured under two conditions: “shoe only”, and “shoe with FCF insole”. Electromyography (EMG) activities of the tibialis anter...
