Gradient leakage attacks are considered one of the wickedest privacy threats in deep learning as attackers covertly spy gradient updates during iterative training without compromising model quality, and yet secretly reconstruct sensitive data using leaked gradients with high attack success rate. Although differential is a defacto standard for publishing models guarantee, we show that differenti...

The maximum rate of pressure rise (dP/dtmax) in radial artery has been proposed as a noninvasive surrogate of aortic dp/dtmax, reflecting left ventricular (LV) contractility in children. The aim of this study was to investigate relationship between aortic and radial dp/dtmax at weaning from cardiopulmonary bypass (CPB) and usefulness of these indices for estimating postoperative outcomes in ped...

In this paper, we focus on lower bounds and algorithms for some basic geometric problems in the one-pass (insertion only) streaming model. The problems considered are grouped into three categories — (i) Klee’s measure (ii) Convex body approximation, geometric query, and (iii) Discrepancy Klee’s measure is the problem of finding the area of the union of hyperrectangles. Under convex body approxi...

Sensitive response to low frequency cochlear distortion products in the auditory midbrain. Abstract During auditory stimulation with several frequency components, distortion products (DP) are generated as byproduct of nonlinear cochlear amplification. After generated DP energy is 20 reemitted into the ear channel where it can be measured as distortion product otoacoustic emission (DPOAE) and it...

Stochastic sandpiles self-organize to an absorbing-state critical point with scaling behavior different from directed percolation (DP) and characterized by the presence of an additional conservation law. This is usually called the C-DP or Manna universality class. There remains, however, an exception to this universality principle: a sandpile automaton introduced by Maslov and Zhang, which was ...

The Rim-Driven Thruster (RDT) is an extraordinary innovation in marine propulsion applications. structure of RDT resembles a Ducted Propeller (DP), as both contain several propeller blades and duct shroud. However, unlike the DP, there no tip clearance directly connected to rim. Instead, gap exists between rim duct. distinctive difference DP causes significant discrepancy performance flow featu...

For solving linear ill-posed problems, regularizationmethods are requiredwhen the right-hand side is with some noise. In this paper regularized solutions are obtained by implicit iteration methods in Hilbert scales. By exploiting operator monotonicity of certain functions and interpolation techniques in variable Hilbert scales, we study these methods under general smoothness conditions. Order o...

OBJECTIVE To assess relations between right ventricular pressure measured with a high fidelity transducer tipped catheter and the characteristics of tricuspid regurgitation recorded with Doppler echocardiography. DESIGN A prospective non-randomised study of patients with severe pulmonary hypertension referred for consideration of lung transplantation. SETTING A tertiary referral centre for ...
