Evaluating the likelihood function of parameters in highly-structured population genetic models from extant deoxyribonucleic acid (DNA) sequences is computationally prohibitive. In such cases, one may approximately infer the parameters from summary statistics of the data such as the site-frequency-spectrum (SFS) or its linear combinations. Such methods are known as approximate likelihood or Bay...

We present a new type of optical wave-front sensor: the sampling field sensor (SFS). The SFS attempts to solve the problem of real-time optical phase detection. It has a high space-bandwidth product and can be made compact and vibration insensitive. We describe a particular implementation of this sensor and compare it, through numerical simulations, with a more mature technique based on the Sha...

KNOPPIX is a bootable CD with a collection of GNU/Linux software. KNOPPIX is very convenient but it requires downloading 700MB iso image and burning a CD-ROM when it is renewed. In order to solve this problem we make SFS-KNOPPIX which boots from Internet with SFS (Self-certifying File System). SFSKNOPPIX requires 20MB boot-loader with Linux-kernel and miniroot. Root file system is obtained from...

OBJECTIVES/HYPOTHESIS To evaluate the efficacy of silk fibroin scaffolds (SFS) and acellular collagen scaffolds (ACS) for the repair of tympanic membrane (TM) in a guinea pig acute perforation model. STUDY DESIGN Experimental animal research. METHODS Seventy-two albino guinea pigs underwent perforation of the right TM and were divided into four experimental groups (n = 18). The perforations...

Feature selection and classification plays an important role in the design and development of a computer aided detection and diagnostics (CAD) tool for breast cancer detection from mammograms. In literature, the various feature selection methods exists such as filter based, wrapper based, and hybrid methods whose aim is to select the most relevant and minimum redundant features from the extract...

Two forms of undulatory locomotion in the lamprey (a lower vertebrate) have been described earlier: fast forward swimming (FFS) used for long distance migrations and slow backward swimming (SBS) used for escape from adverse tactile stimuli. In the present study, we describe another form of escape behavior: slow forward swimming (SFS). We characterize the kinematic and electromyographic patterns...

The nonnegative matrix factorization (NMF) problem D = XY T for a given nonnegative matrix D and with nonnegative factors X and Y can have many solutions aside from trivial permutations or positive multiples of the columns of X and Y . The set of feasible solutions (SFS) is a low-dimensional representation of all possible columns of either X or Y in any NMF of D. The SFS provides important info...

This study aimed to examine the influence of exercise habits and physical fitness level on subjective fatigue symptoms (SFS) in adolescent students. Four hundred and one healthy young male adults (age: 16.5 +/1.2 yr) participated in the physical fitness test of the Ministry of Education, Culture, Sports, Science and Technology in Japan and responded to the questionnaire on exercise habits and S...

Actin stress fibers (SFs) detect and transmit forces to the extracellular matrix through focal adhesions (FAs), and molecules in this pathway determine cellular behavior. Here, we designed two different computational tools to quantify actin SFs and the distribution of actin cytoskeletal proteins within a normalized cellular morphology. Moreover, a systematic cell response comparison between the...

We discuss connection between spin-dependent SFs of nucleons and nu-clei in the deep inelastic lepton scattering. The case of the deuteron is studied in detail in the Bethe-Salpeter formalism. In the present talk we discuss the spin-dependent structure functions (SF) of nuclei and their relation to those of nucleon. Our main focus will be the deuteron, which we study in detail in the covariant ...
