Does there exist O(1)-competitive (self-adjusting) binary search tree (BST) algorithms? This is a well-studied problem. A simple offline BST algorithm GreedyFuture was proposed independently by Lucas [5] and Munro [6], and they conjectured it to be O(1)-competitive. Recently, Demaine et al. [2] gave a geometric view of the BST problem. This view allowed them to give an online algorithm GreedyAr...

Ferroelectric thin films are currently being used to develop tunable microwave circuits based on the electric-field dependence of the dielectric constant. (Ba0.5Sr0.5)TiO3 ~BST! films prepared by sputtering on Pt/TiO2 /SiO2 /Si substrates are found to exhibit a capacitance change ~tunability! of nearly 4:1. Higher tunability has been attributed to the ~100! texturing of the BST films and is a r...

Studies on daily rhythmicity in livestock under natural conditions are limited, and there is mounting evidence that rhythm patterns differ between chronobiological studies conducted in the laboratory and studies conducted under pronounced natural seasonality. Here, we investigated the influence of cold-dry (harmattan) and hot-dry seasons on daily rhythmicity of rectal (RT) and body surface temp...

A nonlinear thermodynamic model is used to investigate the influence of thermal stresses on the room temperature RT pyroelectric properties of 001 -textured polycrystalline barium strontium titanate BaxSr1−xTiO3, BST films with four different compositions on three integrated circuit-friendly substrates: Si, 0001 and 1̄1̄20 sapphire. It is found that the in-plane tensile thermal strain in BST incr...

OBJECTIVE The efficacy and safety of BST-CarGel, a chitosan-based medical device for cartilage repair, was compared with microfracture alone at 1 year during a multicenter randomized controlled trial (RCT) in the knee. The quality of repair tissue of osteochondral biopsies collected from a subset of patients was compared using blinded histological assessments. METHODS The international RCT ev...

Bacterial spot of tomato (BST) is a disease that severely afflicts crops, especially in geographic areas such as the Southeastern U.S., where environmental conditions favor rapid development. Farmers usually use chemical treatments copper–mancozeb mixtures and acibenzolar-S-methyl, among other methods, to manage BST. However, these generally fail improve marketable yields, thus raising question...

The effects of dietary energy and recombinant bovine somatotropin (bST) on pattern of LH release, follicular development, and onset of puberty were studied in 40 Angus heifers. At 7 mo of age, heifers were assigned to a 2 x 2 factorial experiment; the main effects were dietary energy (high [HDE]: 14.15 Mcal of ME/d or moderate [MDE]: 10.84 Mcal of ME/d) and somatotropin (bST; 350 mg every 2 wk ...

Introduction: Bedside Teaching (BST) is defined as teaching in presence of a patient. Literature not clear on learning objectives students BST. The aim this study to investigate the priori students. Next this, we want if were more able meet their own personalized objective, when discussing at start session, and was related satisfaction.

Background/objectives Moderate-to-vigorous physical activity (MVPA) and breaks in sedentary time (BST) have been proposed as viable solutions to improve an older adult's independence, whereas (ST) has associated with detrimental effects. We sought assess the joint effects of ST, BST, MVPA on independence adults determine whether what extent ST relationship is moderated by and/or BST. Design Cro...
