This study is situated in an educational context where secondary Latinx English learners’ enrollment has dramatically increased. However, many face limited access to quality education and lack the skills be college career-ready. To tackle this problem, Language Development–Content-Based Teaching Learning (ELD–CBTL) model designed implemented help shift teachers’ knowledge, beliefs, attitudes, p...

We consider the scenario of a magnetic field orthogonal to a front separating two media of different temperatures and densities, such as cold and warm neutral interstellar gas, in a 2-D plane-parallel geometry. A linear stability analysis is performed to assess the behavior of both evaporation and condensation fronts when subject to incompressible, corrugational perturbations with wavelengths l...

We develop the Reddeld equation for delta-correlated gaussian noise and apply it to the case of two neutrino avor or spin precession in the presence of a noisy matter density or magnetic eld, respectively. The criteria under which physical uctuations can be well approximated by the delta-correlated gaussian noise for the above cases are examined. Current limits on the possible neutrino magnetic...

Observations of far-infrared (FIR) and submillimeter (SMM) polarized emission are used to study magnetic fields and dust grains in dense regions of the interstellar medium (ISM). These observations place constraints on models of molecular clouds, star-formation, grain alignment mechanisms, and grain size, shape, and composition. The FIR/SMM polarization is strongly dependent on wavelength. We h...

We present full-polarization VLBA maps of the ground-state, main-line, Π3/2, J = 3/2 OH masers in 18 Galactic massive star-forming regions. This is the first large polarization survey of interstellar hydroxyl masers at VLBI resolution. A total of 184 Zeeman pairs are identified, and the corresponding magnetic field strengths are indicated. We also present spectra of the NH3 emission or absorpti...

We study dynamical symmetry breaking in three-dimensional QED with a Chern-Simons (CS) term, considering the screening e ect ofN avor fermions. We nd a new phase of the vacuum, in which both the fermion mass and a magnetic eld are dynamically generated, when the coe cient of the CS term equals Ne=4 . The resultant vacuum becomes the nite-density state halflled by fermions. For = Ne=2 , we nd th...

This work investigates some aspects of the transport of low-energy e (Ek . 1 MeV) in the interstellar medium (ISM). We consider resonance interactions with magnetohydrodynamic (MHD) waves above the resonance threshold. Below the threshold, collisions take over and deflect e in their motion parallel to magnetic-field lines. Using Monte-Carlo simulations, we model the propagation and energy losse...

Magnetorheological (MR) uids constitute examples of controllable (\smart") u-ids, whose rheological properties vary in response to an applied magnetic eld. These uids typically consist of micron-sized, magnetizable particles dispersed in a non-permeable carrier uid. The essential characteristic of MR uids is that they may be continuously and reversibly varied from a state of free owing liquids ...

We utilize antiferromagnetically coupled bilayer structures to magnetically tune hysteresis loop properties. Key element of this approach is the non-overlapping switching fi eld distribution of the two magnetic layers that make up the system: a hard magnetic CoPtCrB layer (HL) and a soft magnetic CoCr layer (SL). Both layers are coupled antiferromagnetically through an only 0.6-nm-thick Ru inte...
