Minimax and WLS Designs of Digital FIR Filters Using SOCP for Aliasing Errors Reduction in BI-DAC
This paper presented the optimal minimax and weighted least squares (WLS) methods for designing digital finite impulse response (FIR) filters to reduce the aliasing errors generated by the non-ideality of analog filters and mixers in bandwidth ...

A linear problem of regression analysis is considered under the assumption of the presence of noise in the output and input variables. This approximation problem may be interpreted as an improper interpolation problem, for which it is required to correct

Computing Skinning Weights via Convex Duality
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

The Existence of Nontrivial Solutions to a Class of Quasilinear Equations
In this paper, we study the following quasilinear equation: −divϕ∇u∇u+ϕuu=fu in ℝN, where ϕ∈C1ℝ+,ℝ+ and Φt=∫0tsϕ∣s∣ds. In the Orlicz-Sobolev space, by variational methods and a minimax theorem, we prove the equation has a nontrivial solution.

Abstract I argue that economists' distinction between ‘pure’ and ‘applied’ economic theory is often based on papers' stylistic markers rather than their methodology or scope. I illustrate this point with a model of price competition for boundedly rational consumers, due to Piccione and Spiegler. I first present its original, ‘pure style’ version.

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

Minimax Rates for Statistical Inverse Problems Under General Source Conditions
We describe the minimax reconstruction rates in linear ill-posed equations in Hilbert space when smoothness is given in terms of general source sets. The underlying fundamental result, the minimax rate on ellipsoids, is proved similarly to the seminal ...
