Review of a new report: How is technology addressing the college access challenge? A review of the landscape, opportunities, and gaps

The purpose of this review is to examine and critique a new report on technology in regard to college access. The report itself builds upon a previous Get Schooled report from 2013, using updated information and newer programs and apps. The review summarizes the findings of the author, as well as the compilation of tools and their usefulness for students and families. Centered around the fact that many school districts in low-income areas do not have enough financial resources to fund high school counselor positions, the author suggests supplementing the counselor role with various apps and technology. Although this is not a solution to the issue, the report offers practical resources for both families and professionals in the field of college access. This review critically examines the report and offers a few suggestions omissions in the demographics considered, including students with disabilities and students from bilingual families. Overall the review offers a snapshot of the full report and its application to the field of college access and aims to encourage professionals to utilize the tools provided in the report for both advocacy and practical application

Gravitational Lensing by Asymptotically Flat Wormholes

Natural wormholes and its astrophysical signatures have been sugested in various oportunities. By applying the strong field limit of gravitational lensing theory, we calculate the deflection angle and magnification curves produced by Morris-Thorne wormholes in asimptotically flat space-times. The results show that wormholes act like convergent lenses. Therefore, we show that it is hard to distinguish them from black holes using the deflection's angle of the gravitational lens effect, in contrast with the results reported by Cramer et.al. and Safanova et.al. However, we also show that it is possible, in principle, distinguish them by the magnification curves, in particular, by observing the position of the peak of the Einstein's ring.Comment: 9 pages, 14 figure

Asymptotic Inverse Problem for Almost-Periodically Perturbed Quantum Harmonic Oscillator

Consider quantum harmonic oscillator, perturbed by an even almost-periodic complex-valued potential with bounded derivative and primitive. Suppose that we know the first correction to the spectral asymptotics $\{\Delta\mu_n\}_{n=0}^\infty$ ($\Delta\mu_n=\mu_n-\mu_n^0+o(n^{-1/4})$, where $\mu_n^0$ and $\mu_n$ is the spectrum of the unperturbed and the perturbed operators, respectively). We obtain the formula that recovers the frequencies and the Fourier coefficients of the perturbation.Comment: 6 page

Algebra of chiral currents on the physical surface

Using a particular structure for the Lagrangian action in a one-dimensional Thirring model and performing the Dirac's procedure, we are able to obtain the algebra for chiral currents which is entirely defied on the constraint surface in the corresponding hamiltonian description of the theory.Comment: 10 page
