Optimal Constant-Time Approximation Algorithms and (Unconditional) Inapproximability Results for Every Bounded-Degree CSP [PDF]

open access: yes, 2010
Raghavendra (STOC 2008) gave an elegant and surprising result: if Khot's Unique Games Conjecture (STOC 2002) is true, then for every constraint satisfaction problem (CSP), the best approximation ratio is attained by a certain simple semidefinite ...

On ADS-B Sensor Placement for Secure Wide-Area Multilateration

open access: yesProceedings, 2020
As automatic dependent surveillance–broadcast (ADS-B) becomes more prevalent, the placement of on-ground sensors is vital for Air Traffic Control (ATC) to control the airspace.

On regularity of Max-CSPs and Min-CSPs

open access: yesInformation Processing Letters, 2022
We study approximability of regular constraint satisfaction problems, i.e., CSPs where each variable in an instance has the same number of occurrences. In particular, we show that for any CSP $ $, existence of an $ $ approximation algorithm for unweighted regular Max-CSP $ $ implies existence of an $ -o(1)$ approximation algorithm for weighted Max ...

CSP and anonymity [PDF]

open access: yes, 1996
Security protocols are designed to meet particular security properties. In order to analyse such protocols formally, it is necessary to provide a formal definition of the property that they are intended to provide. This paper is concerned with the property of anonymity.

The Complexity of Combinations of Qualitative Constraint Satisfaction Problems

open access: yes, 2020
The CSP of a first-order theory $T$ is the problem of deciding for a given finite set $S$ of atomic formulas whether $T \cup S$ is satisfiable. Let $T_1$ and $T_2$ be two theories with countably infinite models and disjoint signatures.

Evaluation of Relationships between Corticospinal Excitability and Somatosensory Deficits in the Acute and Subacute Phases of Stroke

open access: yesJournal of Integrative Neuroscience, 2023
Background: Somatosensory deficits are common symptoms post stroke. Repetitive transcranial magnetic stimulation (rTMS) over the motor cortex is able to promote motor rehabilitation, whereby its impact on somatosensory functioning remains unknown.

Institutional Ownership and Corporate Social Performance: Empirical Evidence from Indonesian Companies [PDF]

open access: yes, 2007
Prior research on the relationships of institutional ownership and corporate social responsibility has focused on North American (U.S. and Canada) and European companies. With the passage of Indonesian Law No.

Modeling Robustness in CSPs as Weighted CSPs

open access: yes, 2013
Many real life problems come from uncertain and dynamic environments, where the initial constraints and/or domains may undergo changes. Thus, a solution found for the problem may become invalid later. Hence, searching for robust solutions for Constraint Satisfaction Problems (CSPs) becomes an important goal.

A high-affinity antibody against the CSP N-terminal domain lacks Plasmodium falciparum inhibitory activity [PDF]

open access: yes, 2020
Malaria is a global health concern and research efforts are ongoing to develop a superior vaccine to RTS,S/AS01. To guide immunogen design, we seek a comprehensive understanding of the protective humoral response against Plasmodium falciparum ...

Long-Term MERRA-2 Reanalysis Data Indicate Atmospheric Environmental Changes for Three Major Concentrating-Solar-Power-Plant Project Areas in Xinjiang, China

open access: yesAtmosphere, 2023
The characteristics, distributions, and trends of the aerosol optical depth (AOD) and dust aerosol optical depth (DAOD) of three major concentrating solar power (CSP)-plant project areas (Hami, Turpan, and Ruoqiang) in Xinjiang, China were investigated ...
