We consider two broad families of non-additive loss functions covering a large number of applications: rational losses and tropical losses. We give new algorithms extending the Followthe-Perturbed-Leader (FPL) algorithm to both of these families of loss functions and similarly give new algorithms extending the Randomized Weighted Majority (RWM) algorithm to both of these families. We prove that...
One of the goals of the National Spherical Torus Experiment (NSTX) is to investigate the physics of global mode stabilization in a low aspect ratio device. NSTX has a major radius R0 = 0.86 m, a midplane half-width of 0.7 m, and an on-axis vacuum toroidal field B0 0.6 T and has reached a plasma current Ip = 1.5 MA. Experiments have established the wall-stabilized MHD operating space of the mach...
The problem of the resistive wall mode (RWM) is studied in cylindrical geometry and compared to experimental observations from HBT-EP tokamak. In HBT-EP, a dynamical RWM plasma response is studied by applying static, rotating and phase-flip external magnetic perturbations. The plasma response to the applied perturbation is included via the permeability matrix, P = 1/(−s+iα). Here, s is the norm...
Objective. This study aimed at describing the mechanism of hearing loss in low frequency and the different dynamic behavior of the umbo, the stapes head, and the round window membrane (RWM) between normal guinea pigs and those with endolymphatic hydrops (EH), using a laser Doppler vibrometer (LDV). Methods. Cochlear sections were stained with hematoxylin and eosin (HE) to evaluate the hydropic ...
Thirty-one batchor continuous-flow milk pasteurizers used on commercial dairy and custom calf-feeding operations were surveyed. One sample of raw waste milk (RWM) immediately prior to onfarm pasteurization and one sample of pasteurized waste milk (PWM) immediately after on-farm pasteurization from daily waste milk pools were evaluated. The RWM and PWM samples were evaluated for nutrient composi...
Introduction: The round window membrane (RWM) acts as a pressure-relieving for incompressible cochlear fluid. reinforcement of the RWM has been used surgical intervention treatment superior semicircular canal dehiscence and hyperacusis. aim this study was to investigate how affects sound pressure variations in cochlea. Methods: intracochlear (ICSP) simultaneously measured scala tympani (ST) ves...
This study aimed to investigate the sustained drug release properties and hearing protection effect of polyethylene glycol-coated polylactic acid (PEG-PLA) stealth nanoparticles loaded with dexamethasone (DEX). DEX was fabricated into PEG-PLA nanoparticles using an emulsion and evaporation technique, as previously reported. The DEX-loaded PEG-PLA nanoparticles (DEX-NPs) had a hydrodynamic diame...
OBJECTIVES The aims of this study were to investigate the feasibility of isosorbide delivery into perilymph through the round window membrane (RWM), and to compare the intracochlear isosorbide concentration in perilymph after oral administration (PO) versus that after round window perfusion (RWP). METHODS Sixteen male guinea pigs (32 ears) were used. Isosorbide, an osmotic diuretic, was admin...
Abstract While drinking water is known to create significant health risk in arsenic hazard areas, the role of exposure through food intake less well understood, including impact trade. Using best available datasets on crop production, irrigation, groundwater hazard, and international trade flows, we estimate that globally 17.2% irrigated harvested area (or 45.2 million hectares) 42 main crops a...
