Short direct repeat sequences are often found in regulatory regions of various genes; in some cases they display hypersensitivity to S1 nuclease cleavage in supercoiled plasmids. A non-standard DNA structure (Slipped Loop Structure, or SLS) has been proposed for these regions in order to explain the S1 cleavage data; the formation of this structure may be involved in the regulation of transcrip...

Hybridized two-dimensional materials incorporating domains from the hexagonal boron nitride (h-BN) and graphene is an interesting branch of materials science due to their highly tunable electronic properties. In the present study, we investigate the hydrogenated two-dimensional (2D) h-BN/C superlattices (SLs) with zigzag edges using first-principles calculations. We found that the domain width,...

Minority Carrier Lifetime in Beryllium-Doped InAs/InAsSb Strained Layer Superlattices Report Title Minority carrier lifetimes in undoped and Beryllium-doped Type-2 Ga-free, InAs/InAsSb strained layer superlattices (SLS) with energy gaps as low as 0.165 eV were determined from photoluminescence kinetics. The minority carrier lifetime of 450 ns at 77 K in the undoped SLS confirms a high material ...

In this thesis, we develop and study novel Stochastic Local Search (SLS) algorithms for solving the Most Probable Explanation (MPE) problem in graphical models, that is, to find the most probable instantiation of all variables V in the model, given the observed values E = e of a subset E of V. SLS algorithms have been applied to the MPE problem before [KD99b, Par02], but none of the previous SL...

PURPOSE The purpose of this study was to compare the fracture strength of the metal and the bond strength in metal-ceramic restorations produced by selective laser sintering (SLS) and by conventional casting (CAST). MATERIALS AND METHODS Non-precious alloy (StarLoy C, DeguDent, Hanau, Germany) was used in CAST group and metal powder (SP2, EOS GmbH, Munich, Germany) in SLS group. Metal specime...

It is widely acknowledged that stochastic local search (SLS) algorithms can efficiently find models for satisfiable instances of the satisfiability (SAT) problem, especially for random k-SAT instances. However, compared to random 3-SAT instances where SLS algorithms have shown great success, random k-SAT instances with long clauses remain very difficult. Recently, the notion of second level sco...

Strigolactones (SLs), being a new class of plant hormones, play regulatory roles against abiotic stresses in plants. There are multiple hormonal response pathways, which are adapted by the plants to overcome these stressful environmental constraints to reduce the negative impact on overall crop plant productivity. Genetic modulation of the SLs could also be applied as a potential approach in th...

The Salford Lung Study (SLS) of patients with asthma and chronic obstructive pulmonary disease (COPD) is a practical, community-based, randomized, open-label pragmatic study on the efficacy and safety of the once-daily dry powder inhaler that combines the inhaled corticosteroid fluticasone furoate (FF) with the long-acting beta2 agonist vilanterol (VI). The asthma component of the SLS is not ye...

Studies of fluorescence from endogenous molecules in tissues are common for applications such as detection or characterization of early disease. Breast cancer is one of the most common malignant tumor among women and good screening methods are therefore of considerable interest. We have applied synchronous luminescence spectroscopy (SLS) to examine specimens of excised breast tissues. Measureme...
