piezoelectric microcantilevers (mcs) are a new generation of microbeams used in atomic force microscopes (afms). due to their miniaturization of afms as well as their increased imaging precision and speed, these mcs are more popular than their classical counterparts. given the widespread application of these beams in nanoparticle topography, analysis of their vibrating motion has attracted much...

Many classification schemes for proteins and domains are either hierarchical or semi-hierarchical yet most databases, especially those offering genome-wide analysis, only provide assignments to sequences at one level of their hierarchy. Given an established hierarchy, the problem of assigning new sequences to lower levels of that existing hierarchy is less hard (but no less important) than the ...

We investigate geometrical properties of the random K-satisfiability problem. For large enough K, we prove that there exists a region of clause density, below the satisfiability threshold, where SAT assignments are grouped into well separated clusters. This confirms the validity of the clustering scenario which is at the heart of the recent heuristic analysis of satisfiability using statistical...

In this paper, we introduce a stochastic unsupervised learning method that was used in the 2011 Unsupervised and Transfer Learning (UTL) challenge. This method is developed to preprocess the data that will be used in the subsequent classification problems. Specifically, it performs K-means clustering on principal components instead of raw data to remove the impact of noisy/irrelevant/less-relev...

The purpose of this study was to describe the implementation assignment improve ability children Group B Pembina Raya Kindergarten in recognizing colors. method used research is classroom action (PTK). subjects were Kindergarten, using data collection tools form observation and assignments. From results given assignments, it found that child's recognize colors (pointing, mentioning, grouping) a...

Culture-independent DNA fingerprints are commonly used to assess the diversity of a microbial community. However, relating species composition to community profiles produced by community fingerprint methods is not straightforward. Terminal restriction fragment length polymorphism (T-RFLP) is a community fingerprint method in which phylogenetic assignments may be inferred from the terminal restr...

Differentially protected 1,2-diols were synthesized by enantioselective aldehyde α-oxygenation followed by organomagnesium or -lithium addition. Contrary to a previous report, the resultant diols possess an anti configuration. Good selectivity was achieved regardless of the hybridization state of the nucleophile or the presence or absence of branching. This method was applied to short syntheses...

Many approaches to switching in optoelectronic and optical networks decompose the switching function across multiple stages or hops. This paper addresses the problem of determining whether two multi-stage or multi-hop networks are functionally equivalent. Various ad-hoc methods have been used in the past to establish such equivalences. A systematic method for determining equivalence is presente...

We consider the problem of designing optimal and efficient algorithms for solving tridiagonal linear systems with multiple right-hand side vectors on two-dimensional mesh interconnection networks. We derive asymptotic upper and lower bounds for these solvers using odd-even cyclic reduction. We present various important lower bounds on execution time for solving these systems including general l...

SR is a language for concurrent programming. This paper describes the SR language, presents some examples of SR programs in the context of an undergraduate operating systems course, and provides some programming assignments that can be used in an open laboratory. The SR language can be used by instructors of operating systems courses to give students experience in writing concurrent programs th...
