An Improved Construction of Progression-Free Sets [PDF]

open access: yesProceedings of the Twenty-First Annual ACM-SIAM Symposium on Discrete Algorithms, 2010
The problem of constructing dense subsets S of {1,2,..,n} that contain no arithmetic triple was introduced by Erdos and Turan in 1936. They have presented a construction with |S| = Ω(n^{\log_3 2}) elements. Their construction was improved by Salem and Spencer, and further improved by Behrend in 1946.

Cefdinir Inclusion in Mesoporous Silica as Effective Dissolution Enhancer with Improved Physical Stability

open access: yes, 2021
Objective: The objective of this research was to enhance the physical stability and the dissolution rate of cefdinir, a BCS class IV drug, characterized by low and variable bioavailability due to both its low solubility and low permeability.

CPU Power Modeling Accuracy Improvement Method Based on Training Set Clustering Selection [PDF]

open access: yesJisuanji kexue
Building a high-precision and low-cost CPU power model is crucial for power management and power optimization of computer systems.It is generally believed that the larger the size of the training set,the higher the accuracy of the CPU power model.However,

Improved Slender-Set Linear Cryptanalysis [PDF]

open access: yes, 2015
In 2013, Borghoff et al. introduced a slender-set linear cryptanalysis on PRESENT-like ciphers with key-dependent secret S-boxes. In this paper, we propose an improved slender-set linear attack to PRESENT-like ciphers with secret S-boxes. We investigate three new cryptanalytic techniques, and use them to recover the secret S-boxes efficiently.

Improving Purpose in Life in School Settings

open access: yesInternational Journal of Environmental Research and Public Health, 2023
Background and aim: The dimension of purpose in life (PiL) is one of the core features of eudaimonia and plays a crucial role in developmental settings. However, few studies have examined purpose in life in younger generations and verified if it is amenable to improvements following a wellbeing-promoting intervention.

Genetic characterization of a core set of a tropical maize race Tuxpeño for further use in maize improvement. [PDF]

open access: yesPLoS ONE, 2012
The tropical maize race Tuxpeño is a well-known race of Mexican dent germplasm which has greatly contributed to the development of tropical and subtropical maize gene pools. In order to investigate how it could be exploited in future maize improvement, a

SLDMagic—An Improved Magic Set Technique [PDF]

open access: yesElectronic Workshops in Computing, 1996
We present a rewriting method for Datalog-programs which simulates SLD-resolution more closely than the ordinary “magic set” method does. This is especially advantageous in the case of tail-recursive programs, but already in nonrecursive programs we can often save a number of joins.
