Fingertip forces result from the activation of muscles that cross the wrist and muscles whose origins and insertions reside within the hand (extrinsic and intrinsic hand muscles, respectively). Thus, tasks that involve changes in wrist angle affect the moment arm and length, hence the force-producing capabilities, of extrinsic muscles only. If a grasping task requires the exertion of constant f...

inthis paper, the main aim is to introduce the class $mathcal{u}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings togetherwith its subclasses $mathcal{u}_p(lambda,alpha,beta,k_0)capmathcal {t}_p$ and $mathcal{u}_p(lambda,alpha,beta,k_0)capmathcal {t}_p^0$, andinvestigate the properties of the mappings in these classes. first,we give a sufficient condition for mappings to be in $mathcal{u}_p(l...

purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...

The advent of mini-light-emitting diodes (mini-LEDs) represents a recent advancement in display technology. biggest advantage mini-LEDs over traditional backlight LED panels is that the array facilitates local dimming light intensity. This paper presents large-view-angle (LVA) GaN-based mini-LED chip with batwing angular distribution. By placing translucent layer on mini-LED, light-intensity di...

Introduction Although high-field MRI on the human head offers a number of advantages including increased signal-to-noise ratio (SNR), and higher contrast for certain applications, there are also significant difficulties. Chief among these are the non-uniform tipping (variation of the flip angle in the sample) produced by conventional RF pulses due to the inhomogeneous RF (B1) field intrinsic in...

We report the scalable growth of aligned graphene and hexagonal boron nitride on commercial copper foils, where each film originates from multiple nucleations yet exhibits a single orientation. Thorough characterization of our graphene reveals uniform crystallographic and electronic structures on length scales ranging from nanometers to tens of centimeters. As we demonstrate with artificial twi...

In the presence of a perpendicular weak magnetic field, current filaments in semiconductors can obtain a transverse drift. In the framework of a collective-coordinate ansatz, an expression for the velocity of the filament is derived for a simple type of extrinsic semiconductors. It turns out that the motion is caused by the coupling of the non-uniform Hall angle to the translational Goldstone m...

Angle of Arrival (AoA) estimation that applies wideband channel estimation is superior to the narrowband MUSIC (multiple signal classification) approach, even when averaging its results over the entire relevant band. This work reports the results of indoor AoA estimation based on wideband propagation channel measurements taken over a uniform linear antenna array. The measurements were carried o...

This paper describes an experiment that determined the position, and its associated uncertainty, of a proton at three different depths inside of a polymethyl-methacrylate (PMMA) absorber. These observed positions prove the fact that one can predict the most likely path (MLP) of a proton moving through a uniform medium, as long as the displacement and angle of that proton are known at the absorb...
