Memorandum to House Speaker Carl Albert

Memorandum to Speaker of the House of Representatives Carl Albert from Theodore Sorensen with proposed plans for a scenario where Speaker Albert succeeded to the presidency. Albert requested the memo amid the intensifying Watergate scandal and Vice President Spiro Agnew’s resignation. After Agnew’s resignation on October 10, 1973, Albert was first in the line of presidential succession.https://ir.lawnet.fordham.edu/twentyfifth_amendment_watergate_era/1004/thumbnail.jp

Law: The Most Powerful Alternative to War

The single greatest enemy of law is war. I refer not merely to the history of foreign dictatorships where repression is tightened still further at a time of military conflict. No, I refer also, sad to say, to the painful experience of our own country. Legal tradition gave way to military pressure. But cannot law be employed as the single most powerful alternative to war? That is the supreme challenge to your generation of lawyers, if it is not already too late

A DEIM Induced CUR Factorization

We derive a CUR matrix factorization based on the Discrete Empirical Interpolation Method (DEIM). For a given matrix $A$, such a factorization provides a low rank approximate decomposition of the form $A \approx C U R$, where $C$ and $R$ are subsets of the columns and rows of $A$, and $U$ is constructed to make $CUR$ a good approximation. Given a low-rank singular value decomposition $A \approx V S W^T$, the DEIM procedure uses $V$ and $W$ to select the columns and rows of $A$ that form $C$ and $R$. Through an error analysis applicable to a general class of CUR factorizations, we show that the accuracy tracks the optimal approximation error within a factor that depends on the conditioning of submatrices of $V$ and $W$. For large-scale problems, $V$ and $W$ can be approximated using an incremental QR algorithm that makes one pass through $A$. Numerical examples illustrate the favorable performance of the DEIM-CUR method, compared to CUR approximations based on leverage scores

Hydrodynamics of a new concept of primary containment by energy absorption

Fluid dynamical analysis for idealized reactors system with spherical symmetry determines the effect which the destructive component of a nuclear accident produces on primary containment structures. Steel strands surrounding the reactor cavity in the biological shield exhibit plastic deformation to achieve the energy absorption

Substance Use Among Lesbian, Gay, and Bisexual Clients Entering Substance Abuse Treatment: Comparisons to Heterosexual Clients

Objective: This study evaluated whether sexual orientation-specific differences in substance use behaviors exist among adults entering substance abuse treatment. Method: Admissions records (July 2007–December 2009) were examined for treatment programs in San Francisco, California receiving government funding. Lesbian, gay, and bisexual (LGB) persons (n = 1,441) were compared to heterosexual persons (n = 11,770) separately by sex, examining primary problem substance of abuse, route of administration, age of first use, and frequency of use prior to treatment. Results: Regarding bisexual males, the only significant finding of note was greater prevalence of methamphetamine as the primary substance of abuse. When compared to heterosexual men, gay and bisexual men evidenced greater rates of primary problem methamphetamine use (44.5% and 21.8%, respectively, vs. 7.7%, adjusted odds ratios [ORs] 6.43 and 2.94), and there was lower primary heroin use among gay men (9.3% vs. 25.8%, OR 0.35). Among LGB individuals, race and ethnicity did not predict primary problem substance, except that among LGB men and women, a non-White race predicted cocaine use (OR 4.83 and 6.40, respectively), and among lesbian and bisexual women, Hispanic ethnicity predicted lower odds of primary cocaine use (OR 0.24). When compared to heterosexual men, gay men were more likely to smoke their primary problem substance (OR 1.61), first used this substance at an older age (M = 23.16 vs. M = 18.55, p \u3c .001), and used this substance fewer days prior to treatment (M = 8.75 vs. M = 11.41, p \u3c .001). There were no differences between heterosexual and lesbian or bisexual women. Conclusions: There were unique patterns of substance use for gay and bisexual men entering substance abuse treatment, but women did not evidence differences. Gay men evidenced unique factors that may reflect less severity of use when entering treatment including fewer days of use and a later age of initiation of their primary problem substances. The results underscore the importance of being sensitive to differences between gay, bisexual, and heterosexual males when considering substance use disorders

An asymptotic induced numerical method for the convection-diffusion-reaction equation

A parallel algorithm for the efficient solution of a time dependent reaction convection diffusion equation with small parameter on the diffusion term is presented. The method is based on a domain decomposition that is dictated by singular perturbation analysis. The analysis is used to determine regions where certain reduced equations may be solved in place of the full equation. Parallelism is evident at two levels. Domain decomposition provides parallelism at the highest level, and within each domain there is ample opportunity to exploit parallelism. Run time results demonstrate the viability of the method

Discovery and Assessment of New Target Sites for Anti-HIV Therapies

Human immunodeficiency virus (HIV) infects cells by endocytosis and takes over parts of the cell’s reaction pathways in order to reproduce itself and spread the infection. One such pathway taken over by HIV becomes the inflammatory pathway which uses Nuclear Factor κB (NF-κB) as the principal transcription factor. Therefore, knocking out the NF-κB pathway would prevent HIV from reproducing itself. In this report, our goal is to produce a simple model for this pathway with which we can identify potential targets for anti-HIV therapies and test out various hypotheses. We present a very simple model with four coupled first-order ODEs and see what happens if we treat IκK concentration as a parameter that can be controlled (by some unspecified means). In Section 3, we augment this model to account for activation and deactivation of IκK, which is controlled (again, by some unspecified means) by TNF
