Measurement of theB0→K2*(1430)0γandB+→K2*(1430)+γbranching fractions

2004

We have investigated the exclusive, radiative B meson decays to K2*(1430) in 89* 10^6 BBbar events with the BaBar detector at the PEP-II storage ring. We measure the branching fractions BR(B0 -> K2*(1430)0 gamma) = (1.22 +-0.25 +-0.10)*10^(-5) and BR(B+ -> K2*(1430)+ gamma) = (1.45 +-0.40 +-0.15) * 10^(-5), where the first error is statistical and the second systematic. In addition, we measure the CP-violating asymmetry ACP(B0 -> K2*(1430)0 gamma) = -0.08 +- 0.15 +- 0.01.

Bézier Solutions of the Wave Equation

2004

We study polynomial solutions in the Bezier form of the wave equation in dimensions one and two. We explicitly determine which control points of the Bezier solution at two different times fix the solution.

E decays to ηππ in annihilation at rest

1995

Abstract We have observed the ηπ + π − and ηπ 0 π 0 decay modes of the E meson in p p annihilation at rest into π + π − π 0 π 0 η . The mass and width of the E meson are 1409 ± 3 and 86 ± 10 MeV. The production and decay branching ratio is B( p p → Eππ)B(E → ηππ) = (3.3 ± 1.0) × 10 −3 . With a spin-parity analysis we determine that J P = 0 − . The observation of the ηπ 0 π 0 decay mode establishes that E is isoscalar ( C = +1). We find that E decays to η ( ππ ) s (where ( ππ ) s is an S-wave dipion) and πa 0 (980)(→ πη ) with a relative branching ratio of (78 ± 16) %. Using the K K π production and decay branching ratio measured earlier we determine that B[E → K K π] B[E → ηππ] = 0.61 ± 0.1…

Adducts of free-base meso-tetraarylporphyrins with trihaloacetic acids: Structure and photostability

2020

Abstract Four diverse meso-tetraarylporphyrins in the form of diprotonated adducts with trifluoro-, trichloro-, tribromoacetic acids and acetic acid were investigated in benzene solution. Despite similar structural distortion of the chromophore system due to protonation, the respective adducts demonstrated different photostability when exposed to UV irradiation. The trifluoro- and trichloroacetic adducts, and the acetic acid one, showed some common features both molecular and in the mechanism of photodegradation. However, the tribromo-derivative decayed according to a different kinetic scheme, revealing a considerable impact of the bromine atoms upon the pyrrole units of the porphyrin macro…

Special Education Teachers’ Identification of Students’ Reading Difficulties in Grade 6

2020

his study investigated special educational needs (SEN) teachers’ (n = 29) assessment practices and the accuracy of their ratings of the students’ (M age = 12.75 years, n = 55) skill levels in reading fluency and reading comprehension. Teachers rated their sixth grade students’ fluency and comprehension on a three-point scale, and the students were also tested in group tests. Results showed that SEN teachers used several assessment practices simultaneously but mostly relied on observations. The correlations between the teacher ratings and the test scores were significant but moderate in fluency and weak in comprehension. Only two thirds of low-performing students having difficulties in fluen…

The role of psychological inflexibility in adolescent satisfaction with the educational track and school dropout intentions

2022

This study aimed to obtain novel understanding of the associations between psychological inflexibility and adolescents' engagement with upper secondary studies. The participants were 885 Finnish adolescents (mean age 15.74 at the outset) whose psychological inflexibility was measured with the short form of the Acceptance and Fusion Questionnaire for Youth (AFQ-Y8) in the fall of the final (ninth) grade of basic education. School engagement was measured as satisfaction with the educational track and as school dropout intentions, and they were measured twice in the first study year after the transition to upper secondary education. The results showed that high psychological inflexibility in t…

Clinical Inertia in Poorly Controlled Elderly Hypertensive Patients: A Cross-Sectional Study in Spanish Physicians to Ascertain Reasons for Not Inten…

2013

Clinical inertia, the failure of physicians to initiate or intensify therapy when indicated, is a major problem in the management of hypertension and may be more prevalent in elderly patients. Overcoming clinical inertia requires understanding its causes and evaluating certain factors, particularly those related to physicians.The objective of our study was to determine the rate of clinical inertia and the physician-reported reasons for it.An observational, cross-sectional, multi-center study was carried out in a primary care setting. We included 512 physicians, with a consecutive sampling of 1,499 hypertensive patients with clinical inertia.Clinical inertia was defined when physicians did n…
