for vectors x, y ∈ rn, it is said that x is left matrix majorizedby y if for some row stochastic matrix r; x = ry. the relationx ∼` y, is defined as follows: x ∼` y if and only if x is leftmatrix majorized by y and y is left matrix majorized by x. alinear operator t : rp → rn is said to be a linear preserver ofa given relation ≺ if x ≺ y on rp implies that t x ≺ ty onrn. the linear preservers o...

a method for determination of juglone in leaves and hulls of pterocarya fraxinifolia was developed, based on rp-hplc. this compound was extracted from leaves and hulls by chloroform refluxing about 2 hours. the chloroform was evaporated under low pressure at   50 ºc to produce a dry residue. the remained materials were dissolved in acetonitrile to be used for determination of this compound. app...

OBJECTIVES Discordance between the Gleason score (GS) on needle biopsy (NB) and the GS of the radical prostatectomy (RP) specimen is a common finding. The objective of this study was to evaluate the prognostic significance of these discrepancies with respect to outcomes following RP. METHODS In the study, 6625 men treated by RP were categorized as having NB=RP (68.8%), NBRP ...

BACKGROUND Patient medication adherence is multidimensional and poses significant concerns to health care professionals. One aspect of adherence is a patient forgetting to take their prescribed medication, which may be improved with reminder packaging (RP). The objective of this analysis was to assess the impact of RP on patient adherence to antihypertensive therapy. METHODS This retrospectiv...

BACKGROUND AND PURPOSE The purpose of the study is to study the nerve conductivity of the tibial motor, peroneal motor, peroneal sensory, and sural nerves in patients with primary and secondary Raynaud's phenomenon (RP). SUBJECTS Twenty each: primary RP, secondary RP, and normal controls. METHODS Electromyography using distal latency (DL) and nerve conduction velocity (NCV) as dependent var...

recently, as the result of the development in modern imaging, computerized three dimensional data processing and advanced engineering techniques, an prosthesis that match the skeletal anatomy can be accurately designed from computer aided design (cad) technique and the physical model of prosthesis or skull replica can be produced through rapid prototyping (rp), rapid tooling (rt), and computer ...
