Existence of the D0-D4 Bound State: a detailed Proof

We consider the supersymmetric quantum mechanical system which is obtained by dimensionally reducing d=6, N=1 supersymmetric gauge theory with gauge group U(1) and a single charged hypermultiplet. Using the deformation method and ideas introduced by Porrati and Rozenberg, we present a detailed proof of the existence of a normalizable ground state for this system

The Proposed Environmental Justice Act: I Have a (Green) Dream

This Comment addresses the concept of environmental racism, the tools that have been used to fight it, and the proposed Environmental Justice Act of 1993. Part II begins with an examination of the evidence minority communities have relied on as proof that environmental racism exists. The evidence contained in numerous articles clearly shows inequalities in the amounts of environmental and health hazards minority communities bear, and this evidence validates the existence of pervasive environmental injustice in our society. Part III addresses the limited case law involving attempts by minority communities to challenge perceived environmental racism and assesses the effectiveness of the existing legal tools used in such cases. Part IV of this Comment examines the text of the proposed Environmental Justice Act of 1993. This Part analyzes the Act\u27s potential as a solution to the problem of unequal environmental burdens and identifies the Act\u27s weaknesses in methodology and overall tone. Part V suggests the need for a more effective legislative response to the problem, both by suggesting revisions in the provisions and goals of the Act and by suggesting areas for further consideration. Finally, Part VI concludes that the Act, though a step forward in recognizing the unequal environmental and health burdens nationwide, will not be effective in its present form. It will simply not provide minority communities with effective assistance in their fight against unequal environmental burdens

Physical Properties and Composition Effects on the Reactivity of Calcium-Based Sulfur Sorbents

A detailed comparison between agglomerated pellets of limestone and commercial-grade plaster of Paris was conducted to test the reactivity of the pellets with H2S over three cycles of sulfidation and regeneration. After multicycle testing with 1 vol % H2S at 880 °C, it was determined that the higher surface area exhibited by the plaster of Paris pellets provided a consistently higher reactivity than the limestone pellets. The effects of pore-forming additives on agglomerated limestone pellets was tested with starch, graphite, and poly(vinyl alcohol) (PVA). The results indicated that the PVA−limestone pellets exhibited a higher capacity for sulfur than plain limestone pellets over multiple cycles. A comparison between pellets made of two different grades of plaster of Paris, limestone, calcium carbonate, dolomite, and hydrated dolomite over three cycles of sulfidation and regeneration provided results indicating that plaster of Paris and hydrated dolomite exhibited the best reactivity and thermal stability. The plaster of Paris and hydrated dolomite also exhibited a capacity for H2S over eight cycles of sulfidation and regeneration that proved promising for possible application in IGCC systems

STAR: Sparse Trained Articulated Human Body Regressor

The SMPL body model is widely used for the estimation, synthesis, and analysis of 3D human pose and shape. While popular, we show that SMPL has several limitations and introduce STAR, which is quantitatively and qualitatively superior to SMPL. First, SMPL has a huge number of parameters resulting from its use of global blend shapes. These dense pose-corrective offsets relate every vertex on the mesh to all the joints in the kinematic tree, capturing spurious long-range correlations. To address this, we define per-joint pose correctives and learn the subset of mesh vertices that are influenced by each joint movement. This sparse formulation results in more realistic deformations and significantly reduces the number of model parameters to 20% of SMPL. When trained on the same data as SMPL, STAR generalizes better despite having many fewer parameters. Second, SMPL factors pose-dependent deformations from body shape while, in reality, people with different shapes deform differently. Consequently, we learn shape-dependent pose-corrective blend shapes that depend on both body pose and BMI. Third, we show that the shape space of SMPL is not rich enough to capture the variation in the human population. We address this by training STAR with an additional 10,000 scans of male and female subjects, and show that this results in better model generalization. STAR is compact, generalizes better to new bodies and is a drop-in replacement for SMPL. STAR is publicly available for research purposes at http://star.is.tue.mpg.de.Comment: ECCV 202

Evaluation of the Relevance of a Web-Based Ask an Expert Feature: StratSoy and Soy and Human Health Queries

StratSoy, a state-of-the-art Web-based information system, has an Ask an Expert (AE) feature that allows Web site browsers to question experts in 13 areas including Soy and Human Health (SHH). The objectives of this research were to: a) assess the use of the SHH AE feature; b) examine respondent attitudes about soy-related topics to help guide development of a Frequently Asked Questions (FAQ) section; and c) improve the information dissemination process on the Web site based on the results of this research. Study participants were 50 Web site users and 48 people who were unfamiliar with the site. The results of the study indicated topic areas of interest and additional Web site features desired by the respondents. The findings identified specific areas that may be targeted to improve the Web site
