    This article examines when statements in a registration statement, couched as opinion, can and cannot be considered to be misstatements of material fact that could lead to liability under Section 11 (and potentially other sections) of the Securities Act. The rest of this paper is formatted as follows. We review the Omnicare case, followed by the key cases in the Second, Third, Ninth, and Sixth Circuit Courts of Appeals. The Second, Third, and Ninth Circuits have all required that, in order for there to be an actionable claim under Section 11, the plaintiff must plead not only that the statement or omission was false, but also that the defendant had subjective knowledge that its opinion was false. The Sixth Circuit, although later reversed by the Supreme Court, applied a strict liability interpretation of Section 11 and required only that the fact or omission be false or misleading. The split decisions among the circuits may be the reason that the Supreme Court granted certiorari. Then, we explain the implications of these decisions to future registrants and to professionals preparing opinions that are to be included in registration statements. This article is important to future registrants and opining professionals because of their liability implications. We conclude with the assumption that future cases will decide how to apply the new rational basis test created by the Supreme Court in interpreting when an opinion statement becomes a misstatement of material fact, or leads to an omission that renders a registration statement false or misleading in violation of Section 11

    Conceptual design of an orbital debris collector

    The current Lower Earth Orbit (LEO) environment has become overly crowded with space debris. An evaluation of types of debris is presented in order to determine which debris poses the greatest threat to operation in space, and would therefore provide a feasible target for removal. A target meeting these functional requirements was found in the Cosmos C-1B Rocket Body. These launchers are spent space transporters which constitute a very grave risk of collision and fragmentation in LEO. The motion and physical characteristics of these rocket bodies have determined the most feasible method of removal. The proposed Orbital Debris Collector (ODC) device is designed to attach to the Orbital Maneuvering Vehicle (OMV), which provides all propulsion, tracking, and power systems. The OMV/ODC combination, the Rocket Body Retrieval Vehicle (RBRV), will match orbits with the rocket body, use a spin table to match the rotational motion of the debris, capture it, despin it, and remove it from orbit by allowing it to fall into the Earth's atmosphere. A disposal analysis is presented to show how the debris will be deorbited into the Earth's atmosphere. The conceptual means of operation of a sample mission is described

    Sexually dimorphic effect of aging on skeletal muscle protein synthesis

    BACKGROUND: Although there appear to be no differences in muscle protein turnover in young and middle aged men and women, we have reported significant differences in the rate of muscle protein synthesis between older adult men and women. This suggests that aging may affect muscle protein turnover differently in men and women. METHODS: We measured the skeletal muscle protein fractional synthesis rate (FSR) by using stable isotope-labeled tracer methods during basal postabsorptive conditions and during a hyperaminoacidemic-hyperinsulinemic-euglycemic clamp in eight young men (25–45 y), ten young women (25–45 y), ten old men (65–85 y) and ten old women (65–85 y). RESULTS: The basal muscle protein FSR was not different in young and old men (0.040 ± 0.004 and 0.043 ± 0.005%·h(-1), respectively) and combined insulin, glucose and amino acid infusion significantly increased the muscle protein FSR both in young (to 0.063 ± 0.006%·h(-1)) and old (to 0.051 ± 0.008%·h(-1)) men but the increase (0.023 ± 0.004 vs. 0.009 ± 0.004%·h(-1), respectively) was ~60% less in the old men (P = 0.03). In contrast, the basal muscle protein FSR was ~30% greater in old than young women (0.060 ± 0.003 vs. 0.046 ± 0.004%·h(-1), respectively; P < 0.05) and combined insulin, glucose and amino acid infusion significantly increased the muscle protein FSR in young (P < 0.01) but not in old women (P = 0.10) so that the FSR was not different between young and old women during the clamp (0.074 ± 0.006%·h(-1) vs. 0.072 ± 0.006%·h(-1), respectively). CONCLUSIONS: There is sexual dimorphism in the age-related changes in muscle protein synthesis and thus the metabolic processes responsible for the age-related decline in muscle mass

    BACKGROUND/AIMS: Gentamicin pharmacokinetics have not been described in patients undergoing short-daily hemodialysis (SDHD). The aim of this study is to describe gentamicin pharmacokinetics and dialytic clearance (Cl(dial)) in SDHD patients and simulate gentamicin exposure after six dosing regimens to help guide future dosing. METHODS: Six anuric patients undergoing SDHD were enrolled. Patients received intravenous infusion of 2 mg/kg gentamicin on day 1 after the first HD session followed by HD sessions on days 2, 3, and 4. Blood samples for determination of gentamicin concentrations were serially collected. Gentamicin pharmacokinetic parameters and Cl(dial) and interindividual variability terms (IIV) were estimated using NONMEM VII. Influence of patient weight on systemic clearance (Cl(s)) and central volume of distribution (V(c)) and influence of urea removal estimates on Cl(dial) were assessed. The model was used to simulate gentamicin concentrations after six dosing regimens including pre- and postdialysis as well as daily and every-other-day dosing. RESULTS: A two-compartment model with first-order elimination from central compartment described gentamicin pharmacokinetics. Population estimates for Cl(s) and Cl(dial) were 7.6 and 134 ml/min, respectively. Patient weight was statistically significantly associated with Cl(s) and V(c). Predialysis every-other-day regimens were as effective (C(max) ≥8 mg/l and AUC(48 h) ≥140 mg·h/l) and less toxic (C(min) <2 mg/l and AUC(48 h) <240 mg·h/l) than postdialysis regimens. CONCLUSIONS: Estimated gentamicin Cl(dial) is higher than previous estimates with thrice-weekly regimens. Predialysis every-other-day dosing may be recommended during SDHD

    Maximizing Ponzi Loss Deductions for Estate and Income Tax Purposes: Are Taxpayers Better Off Dead?

    Full text link
    There is a long history of cases interpreting whether a theft loss deduction for securities fraud is allowable for personal income taxes. The cases require that for a theft loss to be actionable as such, it would have to meet the requirements of the common law definition of theft in the U.S. state in which it occurred. This generally requires direct privity between the person claiming the loss and the person who committed the theft. Because most securities transactions are brokered, the direct privity is lost and a theft loss deduction is denied in favor a capital loss. Recently, in a case of first impression, the Tax Court was presented with a similar issue involving the worth of assets for estate taxes. Instead of using the reasoning presented in income tax cases, the Tax Court allowed a theft loss deduction on estate taxes where a Ponzi scheme was uncovered while the estate owned a limited liability company. The sole assets of the company were shares of the security that was involved in the Ponzi scheme. This Article examines the history of the privity requirement for deducting a theft loss for income taxes and how that reasoning now differs from the tax treatment for estate taxes. The Article concludes that there should not be a difference in treatment and that direct privity should not be required for either income or estate taxes

    The implementation research institute: Training mental health implementation researchers in the United States

    Get PDF
    Abstract Background The Implementation Research Institute (IRI) provides two years of training in mental health implementation science for 10 new fellows each year. The IRI is supported by a National Institute of Mental Health (NIMH) R25 grant and the Department of Veterans Affairs (VA). Fellows attend two annual week-long trainings at Washington University in St. Louis. Training is provided through a rigorous curriculum, local and national mentoring, a ‘learning site visit’ to a federally funded implementation research project, pilot research, and grant writing. Methods This paper describes the rationale, components, outcomes to date, and participant experiences with IRI. Results IRI outcomes include 31 newly trained implementation researchers, their new grant proposals, contributions to other national dissemination and implementation research training, and publications in implementation science authored by the Core Faculty and fellows. Former fellows have obtained independent research funding in implementation science and are beginning to serve as mentors for more junior investigators. Conclusions Based on the number of implementation research grant proposals and papers produced by fellows to date, the IRI is proving successful in preparing new researchers who can inform the process of making evidence-based mental healthcare more available through real-world settings of care and who are advancing the field of implementation science

    Detecting covert communication channels in raster images

    Get PDF
    Digital image steganography is a method for hiding secret messages within everyday Internet communication channels. Such covert communications provide protection for communications and exploit the opportunities available in digital media. Digital image steganography makes the nature and content of a message invisible to other users by taking ordinary internet artefacts and using them as cover objects for the messages. In this paper we demonstrate the capability with raster image files and discuss the challenges of detecting such covert communications. The contribution of the research is community awareness of covert communication capability in digital media and the motivation for including such checks in any investigatory analysis

    Accretion of Planetary Material onto Host Stars

    Full text link
    Accretion of planetary material onto host stars may occur throughout a star's life. Especially prone to accretion, extrasolar planets in short-period orbits, while relatively rare, constitute a significant fraction of the known population, and these planets are subject to dynamical and atmospheric influences that can drive significant mass loss. Theoretical models frame expectations regarding the rates and extent of this planetary accretion. For instance, tidal interactions between planets and stars may drive complete orbital decay during the main sequence. Many planets that survive their stars' main sequence lifetime will still be engulfed when the host stars become red giant stars. There is some observational evidence supporting these predictions, such as a dearth of close-in planets around fast stellar rotators, which is consistent with tidal spin-up and planet accretion. There remains no clear chemical evidence for pollution of the atmospheres of main sequence or red giant stars by planetary materials, but a wealth of evidence points to active accretion by white dwarfs. In this article, we review the current understanding of accretion of planetary material, from the pre- to the post-main sequence and beyond. The review begins with the astrophysical framework for that process and then considers accretion during various phases of a host star's life, during which the details of accretion vary, and the observational evidence for accretion during these phases.Comment: 18 pages, 5 figures (with some redacted), invited revie

    After Goeller v. United States, Can the Theft Loss Treatment Now Be Applied to Investments When Corporate Deception Is Present?

    Get PDF
    Traditionally, the theft loss deduction for Federal income tax was limited in several ways. The limitations included requiring that the theft be considered a theft under the state law in which the theft occurred and that there be direct privity between the person committing the theft and the person against whom the theft occurred. The restrictions have made it hard to use the theft loss deduction in most securities fraud cases. This Article examines the history of the theft loss deduction and recent changes that may show a relaxing of some of these restrictions, and how these changes may impact allowing for the theft loss deduction in securities fraud cases
