Temlyakov is co-organizer of a semester at the Isaac Newton Institute

Vladimir Temlyakov's proposal to co-organize a semester at the Isaac Newton Institute for Mathematical Sciences, Cambridge, UK, was recently approved. This will be a six month semester (January 3 - June 28, 2019) on the topic of "Approximation, sampling and compression in data science," and is being organized by: Anders Hansen (University of Cambridge); Alexei Shadrin (University of Cambridge); Vladimir Temlyakov (IMI, University of South Carolina, Steklov Mathematical Institute, Russian Academy of Sciences); and Sergey Tikhonov (Scuola Normale Superiore di Pisa).

Temlyakov's paper named "Classic Paper in Information Theory" by Google Scholar

Vladimir Temlyakov's paper (with D. Donoho and M. Elad), "Stable recovery of sparse overcomplete representations in the presence of noise," IEEE Transactions on Information Theory {\bf 52} (2006), 6--18, has been named "Classic Paper in Information Theory" by Google Scholar. According to Google Scholar, "Classic papers are highly-cited papers in their area of research that have stood the test of time. For each area, we list the ten most-cited articles that were published ten years earlier." Temlyakov's paper is number 7 in the list after classical papers on compressed sensing. Please see the list of 2006 Classics in Information Theory.

Erik Palmer awarded a 2017 Mathematical Sciences Summer Internship

Graduate student Erik Palmer (advised by Paula Vasquez (IMI)) has been offered an internship through the 2017 Mathematical Sciences Summer Internship Program. This program, sponsored by the The National Science Foundation (NSF), Division of Mathematical Sciences (DMS), provides mathematical sciences doctoral students the opportunity to participate in internships at federal national laboratories, industry and other approved facilities, and gain first-hand experience of the use of mathematics in a nonacademic setting to understand the application of advanced mathematical and statistical techniques to "real world" problems. Palmer will spend ten weeks at Lawrence Livermore Labs in Berkeley.

Filaseta awarded 2017 Carolina Trustees Professorship

Dr. Michael Filaseta (IMI) has been awarded the 2017 Carolina Trustees Professorship. The Carolina Trustees Professorship awards are presented to tenured full professors who are committed to teaching excellence in any phase of the university’s educational mission (undergraduate classroom, graduate seminar, laboratories, clinical practice, independent study, supervised research, etc.), and demonstrate a record of outstanding performance in research and in public service activities. Three Carolina Trustees Professorship awards are given each year-- two awards are presented to Columbia campus professors and one to a professor at another USC campus. The awards are presented annually in the amount of $2000 each and given by the members of the University of South Carolina Board of Trustees at the spring commencement dinner.

Vasquez's student is awarded a Magellan Scholar Program grant

Undergraduate student Erin Kalb (mentored by Paula Vasquez (IMI)) is awarded a one year Magellan Scholar Program grant totaling $3,000 for research on: Mathematical Modeling of Pituitary Organogenesis.

"This project focuses on the formulation and solution of mathematical models, closely guided by experiments, that will contribute to our understanding of how the pituitary gland is formed and how different developmental processes affect the final state and function of this gland...

Currently, most of the research on the development of the pituitary gland is solely focused in a biology perspective. We are interested in introducing mathematical models since they provide a way to determine the consistency of experimental observations with testable hypotheses. We will compare the results from the new model to experimental data and refine and adjust the model to account for different situations in the development of the pituitary. These new insights will allow us to inquire into processes, length and time scales that, at the moment, are out of experimental resolution."

Francisco Blanco-Silva participates in USC's Out-to-Lunch Program
Download USC Times March 2017 Interview

Francisco Blanco-Silva was recently interviewed for the March 2017 issue of the USC Times (see online issue here). The article, "Out to Lunch - No Business at Lunch," features, among others, Blanco-Silva, an instructor of mathematics and member of IMI. Blanco-Silva participated in the USC Out-to-Lunch Program with Lyndsey Reynolds, a sophomore psychology major. The Program is designed to promote faculty and undergraduate student interaction outside the classroom. For more information about the program visit:

Hong Wang is awarded an ARO MURI supplement grant

Hong Wang (IMI) is awarded an Army Research Office (ARO) Multidisciplinary University Research Initiatives (MURI) supplement grant totaling $71,963 (with Brown University as the prime institution) for his research on: Fractional PDEs for Conservation Laws and Beyond: Theory, Numerics and Applications.

"Fractional PDEs provide significantly improved modeling and simulation capabilities of complex phenomena. However, it is found recently that numerical approximations to FPDEs often exhibit poor accuracy and artifacts near the boundary of the domain, which in turn pollute the numerical solutions in the interior domain. This phenomenon is in sharp contrast to their integer-order analogues and significantly compromises the great potential of FPDE models. Mathematical analysis reveals that the fundamental reason is that the solutions to FPDEs boundary layers for certain fractional orders.

The USC Team, led by Dr. Hong Wang, will be responsible for conducting rigorous mathematical analysis on adaptively determining the variable-order of the FPDEs near the boundary, to ensure the solutions to the resulting FPDEs to have the same or compatible regularity near the boundary as in the interior domain. This would minimize or eliminate the boundary layer behavior of the solutions, so the FPDEs and their numerical approximations will behave like their integer-order counterparts and minimize or eliminate the numerical artifacts of the FPDE approximations."

Boyce, DiPrima and Meade Publish Two Books on Elementary Differential Equations

As part of its series of books on Differential Equations, Wiley has published the books "Elementary Differential Equations, Enhanced eText, 11th Edition" (ISBN-978-1-119-32063-0) and "Elementary Differential Equations and Boundary Value Problems, Enhanced eText, 11th Edition" (ISBN-978-1-119-38164-8), both by William E. Boyce, Richard C. DiPrima, and Douglas B. Meade (IMI).

Both books are "written from the viewpoint of the applied mathematician, whose interest in differential equations may sometimes be quite theoretical, sometimes intensely practical, and often somewhere in between. The authors have sought to combine a sound and accurate (but not abstract) exposition of the elementary theory of differential equations with considerable material on methods of solution, analysis, and approximation that have proved useful in a wide variety of applications. While the general structure of the book remains unchanged, some notable changes have been made to improve the clarity and readability of basic material about differential equations and their applications.

In addition to expanded explanations, the 11th edition includes new problems, updated figures and examples to help motivate students. The program is primarily intended for undergraduate students of mathematics, science, or engineering, who typically take a course on differential equations during their first or second year of study. The main prerequisite for engaging with the program is a working knowledge of calculus, gained from a normal two‐ or three‐ semester course sequence or its equivalent. Some familiarity with matrices will also be helpful in the chapters on systems of differential equations."
