Deep-sea clams of the family Vesicomyidae live in symbiosis with intracellular chemosynthetic bacteria. These symbionts are transmitted maternally (vertically) between host generations and should therefore show a pattern of genetic variation paralleling that of the cotransmitted host mitochondrion. However, instances of lateral (nonvertical) symbiont acquisition could still occur, thereby decou...

This work adresses the Disturbance Decoupling Problem in linear systems via static output feedback. Necessary and sufficient conditions for solvability in two important families of systems are established. The problem is solvable if and only if a given subspace verifies an invariance property. The set of output feedback matrices which solve the problem is then parameterized through a suitable c...

Abstract Absolute binding free energy calculations with explicit solvent molecular simulations can provide estimates of protein-ligand affinities, and thus reduce the time costs needed to find new drug candidates. However, these be complex implement perform. Here, we introduce software BAT.py, a Python tool that invokes AMBER simulation package automate calculation energies for protein series l...

Piezoresponse forcemicroscopy (PFM) and related bias-induced strain sensing atomic force microscopy techniques provide unique characterization ofmaterial-functionality at the nanoscale. However, these techniques are prone to unwanted artifact signals that influence the vibration amplitude of the detecting cantilever. Here, we show that higher-order contact resonance eigenmodes can be readily ex...

The scalar modes of the geometry induced by dimensional decoupling are investigated. In the context of the low energy string effective action, solutions can be found where the spatial part of the background geometry is the direct product of two maximally symmetric Euclidean manifolds whose related scale factors evolve at a dual rate so that the expanding dimensions first accelerate and then dec...

This paper applies ζ-function regularization to evaluate the 1-loop effective action for scalar field theories and Euclidean Maxwell theory in the presence of boundaries. After a comparison of two techniques developed in the recent literature, vacuum Maxwell theory is studied and the contribution of all perturbative modes to ζ (0) is derived: transverse, longitudinal and normal modes of the ele...

Rapid economic growth in Northwest China has been accompanied by a dramatic increase in carbon emissions. Based on the two-level Logarithmic Mean Divisia Index (LMDI) method, this study decomposes changes in energy-related carbon emissions in Northwest China during 1995–2012 from the regional and provincial perspectives. Further, by constructing an expanded decomposition model of the decoupling...

We discuss the decoupling solution to SUSY flavor problem in the fat brane scenario. We present a simple model to yield the decoupling sfermion spectrum in a five dimensional theory. Sfermion masses are generated by the overlap between the wave functions of the matter fields and the chiral superfields on the SUSY breaking brane. Two explicit examples of the spectrum are given. In building model...

treatment of bath operators by considering two limiting cases for the coupling strengths of system-bath and pure-bath, namely: (i) J < β and (ii) β ≪ J [recall Eq. (18)]. In case (i), the coupling to the environment induces slow dynamics while the environment itself has fast dynamics. In case (ii), the coupling to the environment is fast but relatively stable due to the environment’s slow inter...

Many heteronuclear NMR experiments employ decoupling to collapse the heteronuclear multiplet, using decoupling schemes with a periodic phase modulation like WALTZ, MLEV, or GARP. Because of the periodic nature of these schemes, cycling sidebands are generated, whose intensity can be strongly reduced by decoupling asynchronously. We show that the most common implementation of asynchronous decoup...
