BeSS: An R Package for Best Subset Selection in Linear, Logistic and Cox Proportional Hazards Models
Journal of Statistical Software, 2020 We introduce a new R package, BeSS, for solving the best subset selection problem in linear, logistic and Cox's proportional hazard (CoxPH) models. It utilizes a highly efficient active set algorithm based on primal and dual variables, and supports ...

Intermolecular Interactions in Molecular Organic Crystals upon Relaxation of Lattice Parameters [PDF]
, 2019 Crystal structure prediction is based on the assumption that the most thermodynamically stable structure will crystallize first. The existence of other structures such as polymorphs or from counterenantiomers requires an accurate calculation of the ...

Fretting corrosion of screws contribute to the fixation failure of the femoral neck: a case report
Biosurface and Biotribology, Volume 5, Issue 4, Page 118-123, December 2019., 2019 Fretting corrosion of metal implants has been associated with implant failure and revision surgeries. This report describes the fixation failure of a femoral neck fracture in a 61‐year‐old male patient due to corrosion of three cannulated screws. Radiographic evaluation at the time of primary surgery demonstrated well‐positioning of the cannulated ...

IET Nanodielectrics, Volume 2, Issue 4, Page 129-134, December 2019., 2019 The effective permittivity of low‐density polyethylene with the conductive carbon black (CB) was modelled by COMSOL. The impact of CB content on the electric properties of the composites with different geometry of the inclusions was investigated. The modelling outcomes evidenced that the simulation was in good agreement with the experiment results at ...

An event-related potential study on changes of violation and error responses during morphosyntactic learning [PDF]
, 2009 Based on recent findings showing electrophysiological changes in adult language learners after relatively short periods of training, we hypothesized that adult Dutch learners of German would show responses to German gender and adjective declension ...

Engineering Biology, Volume 3, Issue 3, Page 57-66, September 2019., 2019 Chromobacterium violaceum is a potential industrially relevant chassis due to its cyanogenic properties and diverse metabolic energetics. However, its application in synthetic biology is limited by the lack of characterised genetic parts. Six constitutive promoters of a 100‐fold range in gene expression from the Anderson library were characterised in C.
