Lower Bound on the Overlattice-Based Sieve Algorithm

open access: yesCryptography
Lattice-based cryptography stands as one of the most pivotal candidates in post-quantum cryptography. To configure the parameters of lattice-based cryptographic schemes, a thorough comprehension of their concrete security is indispensable.

Bayesian Cramér-Rao Lower Bound for Magnetic Field-Based Localization

open access: yesIEEE Access, 2022
In this paper, we show how to analyze the achievable position accuracy of magnetic localization based on Bayesian Cramér-Rao lower bounds and how to account for deterministic inputs in the bound.

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Blow-up phenomena for a pseudo-parabolic system with variable exponents

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
In this paper, we consider a pseudo-parabolic system with nonlinearities of variable exponent type \begin{align*} \begin{cases} u_t-\Delta u_t-\operatorname{div}(|\nabla u|^{m(x)-2}\nabla u)=|uv|^{p(x)-2}uv^2 & \mbox{in}\ \Omega\times(0,T),\\

A Column Generation-Based Lower Bound for the Minimum Sum Coloring Problem

open access: yesIEEE Access, 2020
The objective of this paper is to derive a tight and efficient lower bound for the minimum sum coloring problem. This NP-hard problem is a variant of the classical graph coloring problem where the objective is to minimize the sum of the colors.

A Shadow Rate without a Lower Bound Constraint

open access: yesSocial Science Research Network, 2018
We propose a shadow rate that measures the expansionary (contractionary) interest rate effects of unconventional monetary policies that are present when the lower bound is not binding.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

An Optimization Approach of Deriving Bounds between Entropy and Error from Joint Distribution: Case Study for Binary Classifications

open access: yesEntropy, 2016
In this work, we propose a new approach of deriving the bounds between entropy and error from a joint distribution through an optimization means. The specific case study is given on binary classifications.

Efficient optimization of the Held–Karp lower bound

open access: yesOpen Journal of Mathematical Optimization, 2021
Given a weighted undirected graph $G=(V,E)$, the Held–Karp lower bound for the Traveling Salesman Problem (TSP) is obtained by selecting an arbitrary vertex $\bar{p} \in V$, by computing a minimum cost tree spanning $V \backslash \lbrace \bar{p}\rbrace $
