We introduce a novel sampling algorithm for Markov chain Monte Carlo-based Bayesian inference for factorial hidden Markov models. This algorithm is based on an auxiliary variable construction that restricts the model space allowing iterative exploration in polynomial time. The sampling approach overcomes limitations with common conditional Gibbs samplers that use asymmetric updates and become e...

We investigate the properties of the modes supported by three-dimensional subwavelength plasmonic slot waveguides. We show that the fundamental mode supported by a symmetric plasmonic slot waveguide, composed of a subwavelength slot in a thin metallic film embedded in an infinite homogeneous dielectric, is always a bound mode. Its modal fields are highly confined over a wavelength range extendi...

In this paper we discuss the design of a novel category of photonic crystal slabs (PCS) and as an example, we consider structures based on SOI wafers. Fabrication issues related to lithographic accuracy are addressed, too. The geometry consists in a triangular lattice of hexagons having their symmetry axes rotated with respect to the lattice.We show that the mirror-symmetric 'hexagon-type' PCS ...

We analyze the problem of coordinating upon asymmetric equilibria in a symmetric game, such as the battle-of-the-sexes. In repeated interaction, asymmetric coordination is possible possible via symmetric repeated game strategies. This requires that players randomize initially and adopt a convention, i.e a (symmetric) rule which maps asymmetric realizations to asymmetric continuation paths. The ...

During mammalian brain development, neural progenitor cells undergo symmetric proliferative divisions followed by asymmetric neurogenic divisions. The division mode of these self-renewing progenitors, together with the cell fate of their progeny, plays critical roles in determining the number of neurons and, ultimately, the size of the adult brain. In the past decade, remarkable progress has be...

This paper considers arbitrary-length chosen-ciphertext secure asymmetric encryption, thus addressing what is actually needed for a practical usage of strong public-key cryptography in the real world. We put forward two generic constructions, gem-1 and gem-2, which apply to explicit fixed-length weakly secure primitives and provide a strongly secure (IND-CCA2) public-key encryption scheme for m...

We report on vibrational dynamics of water near the surface of AOT reverse micelles studied by narrow-band excitation, mid-IR pump-probe spectroscopy. Evidence of OH-stretch frequency splitting into the symmetric and asymmetric modes is clearly observed for the interfacial H(2)O molecules. The polarization memory of interfacial waters is preserved over an exceptionally extended >10 ps timescale...

The flight dynamics of a compound aircraft are highly coupled and significantly different from those single aircraft. In this paper, the characteristic three-unit connected analyzed in detail. By distinguishing aircraft’s modes into symmetric mode group an asymmetric group, mechanisms by which relative roll impact rigid-body vehicle become clear. trim configuration has profound influence on its...

Here we report the wet-chemical synthesis of asymmetric one-dimensional (1D) silver "nanocarrot" structures that exhibit mixed twins and stacking fault domains along the <111> direction. Oriented attachment is the dominant mechanism for anisotropic growth. Multipolar plasmon resonances up to fourth order were measured by optical extinction spectroscopy and electron energy-loss spectroscopy (EEL...

A novel asymmetric MOSFET with no LDD on the source side is simulated on bulk-Si using a device simulator (SILVACO). In order to overcome the problems of the conventional asymmetric process, a novel asymmetric MOSFET using mesa structure and sidewall spacer gate is proposed which provides self-alignment process, aggressive scaling, and uniformity. First of all, we have simulated to compare the ...
