sulfonic acid-based precursors (sap) play an important role in tailoring mesoporous silica’s and convert them to a solid acid catalyst with a bronsted-type nature. these kinds of solid acids contribute to sustainable and green chemistry by their heterogeneous, recyclable, and high efficiency features. therefore, knowing the properties and reactivity of saps can guide us to manufacture a sulfona...

Non-synonymous SNPs (nsSNPs), also known as Single Amino acid Polymorphisms (SAPs) account for the majority of human inherited diseases. It is important to distinguish the deleterious SAPs from neutral ones. Most traditional computational methods to classify SAPs are based on sequential or structural features. However, these features cannot fully explain the association between a SAP and the ob...

In this paper, we study the behaviour of the Scaling and Probabilistic Smoothing (SAPS) dynamic local search algorithm on the unweighted MAXSAT problem. MAX-SAT is a conceptually simple combinatorial problem of substantial theoretical and practical interest; many application-relevant problems, including scheduling problems or most probable explanation finding in Bayes nets, can be encoded and s...

We have investigated the effect of dawnside subauroral polarization stream (SAPS) and auroral (DAPS) on ionospheric ion upflow in Northern Hemisphere by using four years Defense Meteorological Satellite Program (DMSP) observations. The occurrence rate DAPS is higher than that SAPS. Obvious occurs topside ionosphere around region. SAPS vertical flow weakened when geomagnetic activity increases. ...

Candida albicans is strongly associated with severe early childhood caries (S-ECC). However, the roles of secreted aspartyl proteinases (Saps), an important virulence factor of C. albicans, in the progress of S-ECC are not clear. In our study, the Saps activities were evaluated by the yeast nitrogen base-bovine serum albumi (YNB-BSA) agar plate method and by the MTT method with bovine serum alb...

Anode potential has been shown to be a critical factor in the rate of acetate removal in microbial electrolysis cells (MECs), but studies with fermentable substrates and set potentials are lacking. Here, we examined the impact of three different set anode potentials (SAPs; -0.25, 0, and 0.25 V vs. standard hydrogen electrode) on the electrochemical performance, electron flux to various sinks, a...

Millions of human single nucleotide polymorphisms (SNPs) or mutations have been identified so far, and these variants could be strongly correlated with phenotypic variations of traits/diseases. Among these variants, non-synonymous ones can result in amino-acid changes that are called single amino-acid polymorphisms (SAPs). Although some studies have tried to investigate the SAPs, only a small f...

Recent dynamic local search (DLS) algorithms such as SAPS are amongst the state-of-the-art methods for solving the propositional satisfiability problem (SAT). DLS algorithms modify the search landscape during the search process by means of dynamically changing clause penalties. In this work, we study whether the resulting, ‘warped’ landscapes are easier to search than the landscapes that corres...
