RBPmotif: a web server for the discovery of sequence and structure preferences of RNA-binding proteins
(Nucleic acids research, 2013)RBPmotif web server (http://www.rnamotif.org) implements tools to identify binding preferences of RNA-binding proteins (RBPs). Given a set of sequences that are known to be bound and unbound by the RBP of interest, RBPmotif ... -
Monitoring of actuation conditions in a micro- turbo-generator
(IEEE Sensors Journal, 2013)This paper presents the theory and implementation of an integrated sensing technique for the real-time measurement of applied actuation conditions in a micro-turbo-generator. The device is composed of a microturbine rotor ... -
Target-independent prediction of drug synergies using only drug lipophilicity
(Journal of Chemical Information and Modeling, 2014)Physicochemical properties of compounds have been instrumental in selecting lead compounds with increased drug-likeness. However, the relationship between physicochemical properties of constituent drugs and the tendency ... -
An adhesion-dominated rolling Friction regime unique to micro-scale ball bearings
(Tribology Letters, 2014)We demonstrate that micro-scale rolling bearings exhibit friction and wear properties markedly different from their macro-scale counterparts. A microfabricated testing platform uses variable rolling element diameters or ... -
On the eigenvalues and eigenvectors of a lorentzian rotation matrix by using split quaternions
(Advances in Applied Clifford Algebras, 2014)In this paper, we examine eigenvalue problem of a rotation matrix in Minkowski 3 space by using split quaternions. We express the eigenvalues and the eigenvectors of a rotation matrix in term of the coefficients of the ... -
An investigation on the electromagnetic design optimization of rotary micromachines with double-layer permanent magnets
(Sensors and Actuators A: Physical, 2015)Electromagnetic design optimization of axial-flux rotary micromachines utilizing double-layer permanent magnets is presented and applied to a micro-scale generator/spirometer currently under development. Double-layer magnet ... -
JBASE: Joint Bayesian Analysis of Subphenotypes and Epistasis
(Bioinformatics, 2015)Motivation: Rapid advances in genotyping and genome-wide association studies have enabled the discovery of many new genotype–phenotype associations at the resolution of individual markers. However, these associations explain ... -
Similar and self-similar curves in minkowski n-space
(Bulletin of Korean Mathematical Society, 2015)In this paper, we investigate the similarity transformations in the Minkowski n-space. We study the geometric invariants of nonnull curves under the similarity transformations. Besides, we extend the fundamental theorem ... -
Generating hyperbolical rotation matrix for a given hyperboloid
(Linear Algebra and Its Applications, 2016)Hyperbolic rotation is hyperbolically the motion of a smooth object on general hyperboloids given by −a1x2+a2y2+a3z2=±λ, λ ∈R+. In this paper, we investigate the hyperbolical rotation matrices in order to get the motion ... -
Modeling gene regulation in liver hepatocellular carcinoma with random forests
(BioMed Research International, 2016)Liver hepatocellular carcinoma (HCC) remains a leading cause of cancer-related death. Poor understanding of the mechanisms underlying HCC prevents early detection and leads to high mortality. We developed a random forest ... -
Chemogenomics and orthology‐based design of antibiotic combination therapies
(Molecular Systems Biology, 2016)Combination antibiotic therapies are being increasingly used in the clinic to enhance potency and counter drug resistance. However, the large search space of candidate drugs and dosage regimes makes the identification ... -
Modeling the combined effect of RNA-binding proteins and microRNAs in post-transcriptional regulation
(Nucleic Acids Research, 2016)Recent studies show that RNA-binding proteins (RBPs) and microRNAs (miRNAs) function in coordination with each other to control post-transcriptional regulation (PTR). Despite this, the majority of research to date has ... -

(IEEE Sensors Journal, 2016)The design, optimization, and performance characterization of turbine prototypes for the development of a Microelectromechanical Systems spirometer is reported. Four different turbines were designed based on large-scale ... -
On conformal curves in 2-dimensional de sitter space
(Advances in Applied Clifford Algebras, 2016)In this paper, we examine the pseudo-spherical curves, which are equivalent to each other under the conformal maps preserving a fixed point in the de Sitter 2-space, by using the Clifford algebra Cl 2,1. Also, we find the ... -
Quaking promotes monocyte differentiation into pro-atherogenic macrophages by controlling pre-mRNA splicing and gene expression
(Nature Communications, 2016)A hallmark of inflammatory diseases is the excessive recruitment and influx of monocytes to sites of tissue damage and their ensuing differentiation into macrophages. Numerous stimuli are known to induce transcriptional ... -
Inferring RBP-mediated regulation in lung squamous cell carcinoma
(Plos One, 2016)RNA-binding proteins (RBPs) play key roles in post-transcriptional regulation of mRNAs. Dysregulations in RBP-mediated mechanisms have been found to be associated with many steps of cancer initiation and progression. Despite ... -
