Site-Directed Insertion: Decision Problems, Maximality and Minimality

Site-directed insertion is an overlapping insertion operation that can be viewed as analogous to the overlap assembly or chop operations that concatenate strings by overlapping a suffix and a prefix of the argument strings. We consider decision problems and language equations involving site-directed insertion. By relying on the tools provided by semantic shuffle on trajectories we show that one variable equations involving site-directed insertion and regular constants can be solved. We consider also maximal and minimal variants of the site-directed insertion operation

Experimental investigations for dust build-up on low-iron glass exterior and its effects on the performance of solar PV systems

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this recordThe performance of solar photovoltaic (SPV) power plants is adversely affected by soiling losses caused by natural dust deposition on the module surface. The size and density of dust particles vary depending on the location. Thus, it is essential to investigate the impact of dust collection on SPV module performance. This work investigates the effect of dust build-up on the low-iron glass surface and the performance of SPV modules. To analyze the characteristics of these dust particles, low-iron glass samples have been chosen, which resemble a front glass surface of the SPV module. To study the holistic pattern of the natural dust accumulation of a particular area, low-iron glass samples have been placed with three different positions like vertical, horizontal, and local tilt angle for Building Integrated Photovoltaic Systems (BIPV) and rooftop PV power plant applications. The mineralogical study of dust particles provides insight in determining the transmittance loss from the glass surface of solar PV modules due to the local soiling loss. Furthermore, the electrical power output of the SPV modules has been monitored at various levels of dust accumulation. Moreover, these findings indicate that natural dust deposition at selected site locations significantly reduces energy generation from PV modules.BITS-Pilani, Hyderabad CampusEngineering and Physical Sciences Research Council (EPSRC

Compartive Modeling of Human Siglec-8 Membrane Protein

Many cells are present in our body and play different role. But some cells only involved in the inflammatory process.Siglec-8 is a member of the CD33 Sialicacid binding Ig-like lectins membrane proteins that constitute a distinct subset of the Ig super- family and are characterized by their sequence similarities and abilities to bind sialic acids in glycoproteins and glycolipids . Siglec-8 found predominantly on human eosinophils. Siglec is also present in the airway passages.so they involved in the asthma. Thus, it is a potential chemotherapeutic target for asthma treatment. Structure of this enzyme in Homosapiens has not yet been elucidated. We used the structural template of N-Terminal Domains of Native Siglec-5 from Homosapiens for modeling of siglec-8 structure by using Modeller.Thus we analyses and propose the usefulness of the modeled siglec-8 for the design of suitable agonist towards the treatment of asthma.Keywords: Asthma; Siglec-8; Homo sapiens; Modeler; Homology Modeling

Site-Directed Deletion

International audienceWe introduce a new bio-inspired operation called a site-directed deletion motivated from site-directed mutagenesis performed by enzymatic activity of DNA polymerase: Given two strings x and y, a site-directed deletion partially deletes a substring of x guided by the string y that specifies which part of a substring can be deleted. We study a few decision problems with respect to the new operation and examine the closure properties of the (iterated) site-directed deletion operations. We, then, define a site-directed deletion-closed (and-free) language L and investigate its decidability properties when L is regular or context-free
