For a microelectromechanical (MEM) filter a new approach for the coupling spring design is presented. A designed MEM bandpass filter consists hereby of two laterally driven resonance structures which are coupled by a mechanical spring. For this structure an electrical equivalent circuit is presented and analyzed analytically. The transfer function and the correlation between the bandwidth and t...

Amphiphilic helical peptides exhibit an insertion transition when they interact with lipid bilayers. At low concentrations, the peptides adsorb at the hydrophilic-hydrophobic interface with the helical axes parallel to the bilayer surface. However, if the peptide concentration is above a critical value, a macroscopic fraction of the peptide molecules insert perpendicularly into the bilayer. The...

2 The problem of inserting a new element x into a lattice of types L is addressed in the paper. As the poset L + x obtained by the direct insertion of x in L, is not necessarily a lattice, some set of auxiliary elements should be added to restore the lattice properties. An approach towards the lattice insertion is presented which allows the set of auxiliary elements to be kept minimal. The key ...

We consider the insertion of a new element x in a lattice of types L. As the poset L + x obtained by the direct insertion of x in L, is not necessarily a lattice, a set of auxiliary elements should be added in order to restore the lattice properties. We describe an approach towards the lattice insertion based on a global deenition of the set of necessary auxiliary elements and their location in...

In recent years, the design of artificial metalloenzymes obtained by the insertion of homogeneous catalysts into biological macromolecules has become a major field of research. These hybrids, and the corresponding X-ray structures of several of them, are offering opportunities to better understand the synergy between organometallic and biological subsystems. In this work, we investigate the res...

Comprehensive analysis of gene function requires the detailed examination of mutant alleles. In Arabidopsis thaliana, large collections of sequence-indexed insertion and chemical mutants provide potential loss-of-function alleles for most annotated genes. However, limitations for phenotypic analysis include gametophytic or early sporophytic lethality, and the ability to recombine mutant alleles...

The FliM protein of Escherichia coli is required for the assembly and function of flagella. Genetic analyses and binding studies have shown that FliM interacts with several other flagellar proteins, including FliN, FliG, phosphorylated CheY, other copies of FliM, and possibly MotA and FliF. Here, we examine the effects of a set of linker insertions and partial deletions in FliM on its binding t...

We regulate Witten’s open superstring field theory by replacing the picturechanging insertion at the midpoint with a contour integral of picture changing insertions over the half-string overlaps of the cubic vertex. The resulting product between string fields is non-associative, but we provide a solution to the A∞ relations defining all higher vertices. The result is an explicit covariant super...

considering iran geographical location, water is the most limited factor in agriculture section. therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. the purpose of this study is assigning cultivation pattern based on economic value of water in gotvand township in agronomic year 2008-2009. so it was necessary to computes the...

objectives: the purpose of current semi-experimental study was a survey on effect abstract  of 16 week walking on psychosocial functioning related to quality of life among 60 to 75 years old men. methods & materials: for this reason, short form of health-related quality of life questionnaire (sf-36) and geriatric depression scale (gds) had been distributed to the subjects at 2 times of pre-test...
