Quality of life of nursing students during COVID-19, the mediating role of resilience: Systematic review
No full textQuality of life of nursing students is significantly lower during COVID-19, and resilience has a protective role on the QoL of students. Individuals engaged in self-compassion, mindfulness practice, self-regulation techniques, and evoking positive emotions had better quality of life through resilience
Polarimetric radar modeling of mixtures of precipitation particles
No full textWith the recent advances of dual-polarized radar techniques in meteorology it is now possible to deduce precipitation microphysical characteristics in far more detail than possible with reflectivity measurements alone. Radar parameters such as differential reflectivity and differential phase between horizontal and vertical polarizations have been studied in detail as well as linear depolarization ratio, copolar correlation coefficient, and backscatter differential phase. While these parameters can be linked to certain microphysical properties of specific classes of precipitation such as raindrops or hail, very little study has been directed at the practically important cases of mixtures of different types of precipitation particles such as rain, hail, graupel, ice crystals, and snow. Each type can have different size, shape, orientation, and dielectric constant distributions. The treatment here is rigorous and is based on the Mueller matrix formulation. Radar parameters are derived from the averaged Mueller matrix computations. Careful consideration is given to the orientation and size distributions of the different particle types. After calculating single particle scattering characteristics, some simple two-component mixtures such as rain/hail and ice crystals/snow are considered. Finally, a 2D numerical cloud model is used to simulate the rain, hail/graupel, and snow fields of an evolving convective storm from which the radar parameters are derived for the initial, peak, and dissipating stages of the storm. Model computations are performed at C and S-band frequencies.This work was supported by the FAA under Contract DTFA01-90-Z-02005 and the National Science Foundation under Contract ATM-9214864.

A Triangular-shaped Quarter-mode Substrate Integrated Waveguide based Antenna for WBAN Applications
No full textIn this study, a compact quarter-mode substrate integrated waveguide (QMSIW) based dual-band antenna is proposed for wireless body area network applications. A QMSIW resonator is realised by splitting the full-mode substrate integrated waveguide cavity along the perfect magnetic conductor walls. The proposed antenna preserves the fundamental mode TE110 and the third order mode TE220 of the square SIW cavity. The proposed antenna is linearly polarised in the lower band at 2.45 GHz and circularly polarised in the higher frequency band at 5.8 GHz. The on-body performance of the antenna is validated on a piece of pork muscle tissue and it has been found to be stable with respect to surroundings. The proposed antenna covers the ISM bands 44 MHz (2.445 GHz - 2.489 GHz) and 225 MHz (5.730 GHz - 5.955 GHz) at 2.45 GHz and 5.8 GHz, respectively. The measured gain of the antenna on pork tissue is 1.87 dBi and 5.5 dBi at two bands. In addition, the specific absorption rate is obtained of 0.65 mW/g and 1.51 mW/g at two bands (wext = 2 mm), averaged over 1 g of muscle with 100mW input power. Moreover, the simulated and experimental results demonstrate a good agreement
Properties of relaxed trajectories of non-linear fractional impulsive control systems
No full textA non-convex control system governed by a nonlinear impulsive evolution
equation of Hilfer fractional order in a Banach space is considered. The
existence of admissible state-control pair is established. Then the
introduction of suitable measure-valued control convexifies the system, and the
relaxed system is obtained. Further, the relaxation theorem for the described
class is proved along with the existence of optimal relaxed control.Comment: 21 page
