A Note About the Cover Art
Give Us Opportunities, 2016
Artist: Tee
Digital Print
Performing Statistics is a cultural organizing project that uses art to model, imagine, and advocate for alternatives to youth incarceration. Every summer, the project creates art with a group of teens in the Richmond Juvenile Detention Center’s post-dispositional program about their experiences navigating the justice system and their vision for a world without youth prisons. The artwork is then produced in a number of ways in order to reach decision-makers in the education, law enforcement, and juvenile justice systems. The project’s ethos looks to young people impacted by the juvenile justice system as experts society should listen to when considering policies that most impact them. Give Us Opportunities was created in the summer of 2016 and speaks to the kinds of investments young people would like to see to keep them out of the system. Jobs, credible messenger mentors, culturally competent after-school programming, more supportive educational environments, and stable housing are just a few examples of the kinds of investments that come up regularly in the project’s programming. In 2020, Performing Statistics will premier No Kids in Prison, a national touring exhibition that will amplify youth justice movements across the country and weave a national narrative of youth stories, dreams, and demands. More information about the project can be found at www.performingstatistics.org. The cover art is used with permission from ART 180
Existence and Regularity of Optimal Shapes for Elliptic Operators with Drift
This paper is devoted to the study of shape optimization problems for the
first eigenvalue of the elliptic operator with drift L = --+V (x)\cdot
\nabla with Dirichlet boundary conditions, where V is a bounded vector field.
In the first instance, we prove the existence of a principal eigenvalue
\_1(, V) for a bounded quasi-open set which enjoys
similar properties to the case of open sets. Then, given m > 0 and
0, we show that the minimum of the following non-variational problem min
\_1(, V) : D quasi-open, ||
m, |V|\_{\infty} . is achieved, where the box D R^d is a
bounded open set. The existence when V is fixed, as well as when V varies among
all the vector fields which are the gradient of a Lipschitz function, are also
proved. The second interest and main result of this paper is the regularity of
the optimal shape * solving the minimization problem min
\_1(, ) : D quasi-open, ||
m , where is a given Lipschitz function on D. We prove that the
topological boundary * is composed of a regular part which
is locally the graph of a C ^{1,} function and a singular part which is
empty if d < d * , discrete if d = d * and of locally finite H^{d--d *}
Hausdorff measure if d > d * , where d * {5, 6, 7} is the smallest
dimension at which there exists a global solution to the one-phase free
boundary problem with singularities. Moreover, if D is smooth, we prove that,
for each x * D, *
is C^{ 1,} in a neighborhood of x, for some 1 /2. This
last result is optimal in the sense that C ^{1,1/2} is the best regularity that
one can expect
Free boundary regularity for a multiphase shape optimization problem
In this paper we prove a regularity result in dimension two
for almost-minimizers of the constrained one-phase Alt-Caffarelli and the
two-phase Alt-Caffarelli-Friedman functionals for an energy with variable
coefficients. As a consequence, we deduce the complete regularity of solutions
of a multiphase shape optimization problem for the first eigenvalue of the
Dirichlet-Laplacian up to the fixed boundary. One of the main ingredient is a
new application of the epiperimetric-inequality of Spolaor-Velichkov [CPAM,
2018] up to the boundary. While the framework that leads to this application is
valid in every dimension, the epiperimetric inequality is known only in
dimension two, thus the restriction on the dimension
Going to Hell in a HHS Notice: The Contraceptive Mandate\u27s Next Impermissible Burden on Religious Freedom
The Affordable Care Act’s requirement that eligible religious organizations submit a notice objecting to providing their employees contraceptive coverage if they religiously object to contraception or abortifacients is as simple as filing a piece of paper. But to a collection of Catholic petitioners, complying with this requirement gives rise to “scandal” and causes them to “materially cooperate” with sin. Filing a piece of paper may seem far outside any exercise of religion, but these groups sincerely believe that the one page notice burdens their religious beliefs.
Zubik v. Burwell, like Burwell v. Hobby Lobby Stores, presents a conflict between the ACA and the Religious Freedom Restoration Act (RFRA), a statute that gives religious groups a shield and a sword against federal laws and regulations that interfere with their free exercise of religion. In Hobby Lobby the Supreme Court held that RFRA prohibits the Government from forcing certain closely-held, religious corporations to provide contraceptive coverage to their employees. Here, the author argues that the Court should extend Hobby Lobby and hold that the accommodation impermissibly burdens these religious groups’ beliefs under the demanding RFRA statute
Unprotected and Unpersuaded: The FCC\u27s Flawed Merger Review Procedures
In CBS Corporation v. FCC, the D.C. Circuit struck down the Federal Communication Commission’s rules for protecting confidential information that it collects during certain merger proceedings. In response, the Commission released a new order, pursuant to the Charter, Time Warner, and Bright House merger proceeding, for protecting confidential information. This iBrief analyzes the policy and legal implications of the Order, arguing that the Order is unlawful because it violates the Trade Secrets Act and notice-and-comment rulemaking requirements
Archive Web Sites Using AJAX and GWT
The last three years have seen much change in web technology and have created some significant breakthroughs. We are now able to let the user interact with an archive from the Web browser in ways we have never thought possible. The Web browser is no longer a glorified batch processing terminal, but an interactive environment that allows the user to have a similar experience as one might expect with an installed desktop application. We can now provide web based FITS viewing and interaction without any plugins. Much of this is made possible using AJAX. AJAX technology has made an major impact on how we think about developing on the Web. Users expect more and are drawn to more interactive and intuitive web sites. The problem with the Javascript part of AJAX is that it does not scale well to large Web applications, is hard to debug, and a lot of browser specific code is required. Google Web Toolkit (GWT) provides the solution to this problem. With GWT, you write code in Java that is compiled into Javascript. GWT handles many of the browser-specific issues and provides you an environment to develop very powerful web sites. This talk will discuss the concepts behind AJAX and GWT. We will also show how using these technologies in an archive web site will create a truly interactive experience
Sulfur amino acid requirements of broilers from two to five weeks of age
Phase-feeding (PF) in broiler chickens has been researched as a way to reduce feed costs without reducing growth performance and yield. Predicted amino acid requirements for PF are generated using linear regression equations derived from best estimates of lysine (Lys), sulfur amino acid (SAA), and threonine (Thr) requirements. During the late starter and early grower periods, predicted requirements for the SAA methionine (Met) and cysteine (Cys) are higher than levels recommended by the National Research Council (NRC), and previous research suggests that SAA may be lowered during the grower period without sacrificing growth performance or yield. The objective of this study was to estimate Met and Cys requirements for broilers from 2 to 5 weeks of age. In Experiment 1, a Met-deficient corn-peanut meal diet was formulated to contain excess Cys, so that supplemental Met was not utilized for Cys synthesis. The basal diet for Experiment 2 met the Met requirement but was deficient in Cys. Graded levels of Met (0, 0.045, 0.09, 0.135, and 0.225%) and Cys (0, 0.035, 0.070, 0.105, 0.140, 0.175%) were added in Experiments 1 and 2, respectively, and diets were fed to five replicates of five broilers per pen. Broken-line analysis was used to estimate SAA requirements. The digestible Met and Cys requirements from 2 to 5 weeks of age were 0.33% and 0.31%, respectively. Requirement estimates were lower than those predicted by PF or recommended by NRC, indicating that lower SAA levels may be utilized in a PF progra
The Effects of BACE and Its Targets on Age-related Seizures in \u3cem\u3eDrosophila\u3c/em\u3e
The presence of Beta-Amyloid (Aβ) containing plaques in the brain is one of the histological hallmarks of Alzheimer’s Disease. β-secretase (BACE) is the enzyme responsible for producing this Aβ cleavage product and has also been shown to affect myelination and general neuronal activity. Observations from geriatric medicine suggest that there may be an increase in seizure activity associated with Alzheimer’s Disease. Preliminary data suggests that both over- and under-expression of BACE contributes to mechanically stimulated seizures in Drosophila. In vertebrates, seizure activity has been correlated with many factors including Neuregulin production and Na+ Pump activity. Both of these proteins have also been shown to require BACE activity for proper function. However, their roles in BACE related seizures remains unknown. Here we are following up on this preliminary study and exploring the roles of Vein (the Drosophila homolog of Neuregulin) and Numb (a negative regulator of the Notch Pathway). We have confirmed that any perturbation in dBACE (Drosophila BACE) levels causes a significant increase in age related seizures, suggesting that that BACE levels must be tightly regulated. In addition an increase of Vein levels also cause a dramatic increase in seizure amounts and duration suggesting that BACE, at least in part, is acting through this signaling pathway. Understanding which BACE related signaling pathways are responsible for age related seizure activity can lead to new treatments which will hopefully slow the progression of Alzheimer’s and other related neurodegenerative diseases
