Sparse kernel density construction using orthogonal forward regression with leave-one-out test score and local regularization [PDF]
, 2004 This paper presents an efficient construction algorithm for obtaining sparse kernel density estimates based on a regression approach that directly optimizes model generalization capability.

Molecular Oncology, EarlyView.Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Orthogonal learning particle swarm optimization [PDF]
, 2010 Particle swarm optimization (PSO) relies on its learning strategy to guide its search direction. Traditionally, each particle utilizes its historical best experience and its neighborhood’s best experience through linear summation.

Spatial heterogeneity of hotspot mutations and clonal relatedness in ovarian endometrioid carcinoma
Molecular Oncology, EarlyView.Spatially resolved analysis revealed heterogeneous distributions of selected cancer‐associated mutations within ovarian endometrioid carcinomas. Shared mutations between paired endometrial and ovarian tumors supported clonal relatedness. These findings highlight the value of sampling multiple tumor regions when interpreting molecular profiles ...

Four Wave Mixing-Based Time Lens for Orthogonal Polarized Input Signals
IEEE Photonics Journal, 2017 We present highly efficient time-lenses for orthogonal polarized signal waves with a specific state of polarization. Our four-wave mixing based time-lenses exploit polarization mode dispersion to compensate for chromatic dispersion.

Feedback communication using orthogonal signals [PDF]
IEEE Transactions on Information Theory, 1969 We consider a feedback communication system in which the forward and feedback channels are disturbed by additive noise and constrained in average power. Two block coding schemes are proposed in which the signals are orthogonal waveforms. A finite number of forward and feedback transmissions per message is made.

FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
