Developing a New Partnership
Many factors contribute to the success and impact of a Mathematics Resource Teacher on K-5 mathematics instruction. Developing a strong partnership with stakeholders and sharing a common vision for quality mathematics instruction are key factors in the successful implementation of the Mathematics Resource Teacher program. In this article, we share the experience of elementary school principal, Timothy Martino, as he prepared to open a new elementary school in August 2012. Frederick Douglass Elementary opened with a full-time, school-embedded Mathematics Resource Teacher, Mrs. Cindy Brady. Timothy Martino and Mrs. Brady developed a partnership with division-level central office staff and with the teachers of Frederick Douglass Elementary. Thus, they began the journey toward improving mathematics instruction for students through a team approach
The careless use of language in quantum information
An imperative aspect of modern science is that scientific institutions act
for the benefit of a common scientific enterprise, rather than for the personal
gain of individuals within them. This implies that science should not
perpetuate existing or historical unequal social orders. Some scientific
terminology, though, gives a very different impression. I will give two
examples of terminology invented recently for the field of quantum information
which use language associated with subordination, slavery, and racial
segregation: 'ancilla qubit' and 'quantum supremacy'.Comment: 2 page
Implications of Lee-Yang Theorem In Quantum Gravity
The contributions of this note are twofold: First, it gives a generic recipe
to apply Lee-Yang Theorem to solutions of Einstein field equations. Secondly,
this existence of the applicability of Lee-Yang Theorem on a partition function
of spacetime manifolds might also shed some light on the connection between the
number theory, gravity, and gauge field theory. The connection to the Riemann
Zeta function is quite interesting when one is also studying the distribution
of non-trivial zeroes of the Riemann Zeta function\cite{BRiemann}, or its
generic form (Dirichlet L-function)
Comment on "Optimum Quantum Error Recovery using Semidefinite Programming"
In a recent paper ([1]=quant-ph/0606035) it is shown how the optimal recovery
operation in an error correction scheme can be considered as a semidefinite
program. As a possible future improvement it is noted that still better error
correction might be obtained by optimizing the encoding as well. In this note
we present the result of such an improvement, specifically for the four-bit
correction of an amplitude damping channel considered in [1]. We get a strict
improvement for almost all values of the damping parameter. The method (and the
computer code) is taken from our earlier study of such correction schemes
(quant-ph/0307138).Comment: 2 pages, 1 figur
Dark-cycle monitoring of biological subjects on Space Station Freedom
The operational environment for biological research on Space Station Freedom will incorporate video technology for monitoring plant and animal subjects. The video coverage must include dark-cycle monitoring because early experiments will use rodents that are nocturnal and therefore most active during the dark part of the daily cycle. Scientific requirements for monitoring during the dark cycle are exacting. Infrared (IR) or near-IR sensors are required. The trade-offs between these two types of sensors are based on engineering constraints, sensitivity spectra, and the quality of imagery possible from each type. This paper presents results of a study conducted by the Biological Flight Research Projects Office in conjunction with the Spacecraft Data Systems Branch at ARC to investigate the use of charged-coupled-device and IR cameras to meet the scientific requirements. Also examined is the effect of low levels of near-IR illumination on the circadian rhythm in rats
