Using Precision Teaching to Improve Typically Developing Student’s Mathematical Skills Via Teleconferencing

This study evaluated the effects of Precision Teaching in improving typically developing students’ mathematical skills when delivered via teleconferencing in India. Four students received Precision Teaching, while nine acted as control participants. Precision teaching involved instruction in three mathematical skills; two prerequisite skills and the primary skill of mixed addition and subtraction facts. Instruction included untimed practice, timed practice, goal-setting, graphing, and a token economy. Participants who received Precision Teaching received ten practice sessions for the prerequisite skills and 55 sessions for the primary skill. The results demonstrated improvements in the prerequisite skills of varied magnitude and considerable improvements in the primary skill, which were maintained above baseline performance levels. In addition, those who received Precision Teaching were below the 15th percentile rank at the initial assessment and above the 65th percentile at the post-intervention assessment in the math fluency subtest of the Kaufman Test of Educational Achievement—Third Edition. Control participants did not demonstrate similar improvements. Results suggest that Precision Teaching could produce accelerated outcomes even when delivered via teleconferencing. Therefore, it could be a valuable system for helping students ameliorate potential learning losses resulting from the COVID-19 pandemic

Braving the attitude of altitude: Caragana jubata at work in cold desert of Himalaya

The present work was conducted to understand the basis of adaptation in Caragana jubata in its niche environment at high altitude cold desert of Himalaya. Molecular data showed predominance of genes encoding chaperones and those involved in growth and development at low temperature (LT), a major cue operative at high altitude. Importantly, these genes expressed in C. jubata in its natural habitat. Their homologues in Arabidopsis thaliana, Oryza sativa, and Glycine max did not exhibit similar trend of gene expression at LT. Constitutive expression and a quick up-regulation of the above genes suggested the ability of C. jubata to adjust its cellular machinery to maintain growth and development in its niche. This was reflected in LT50 (the temperature at which 50% injury occurred) and LT mediated photosynthetic acclimatory response. Such molecular and physiological plasticity enables C. jubata to thrive in the high altitude cold desert of Himalayas

Precision measurement of the structure of the CMS inner tracking system using nuclear interactions

The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using these vertices. These measurements are important for detector simulations, detector upgrades, and to identify any changes in the positions of inactive elements

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios
