The calculation of real-μ and controller design (1994)

Abstract For a SISO, linear and time-invariant plant, with one real parameter uncertainty and one complex fictitious perturbation representing performance uncertainty, the structured singular value, μδ˜(M), is calculated. Then μ — K iteration can be used to design a μ-optimal controller. A simple design example is considered. The results are compared with those obtained for the same system with the real parameter modelled as a complex perturbation. This illustrates the conservatism that can be introduced by treating real uncertainty as complex uncertainty. Additional informationNotes on contributorsJ.-L.

Baseband receiver algorithms for 4g co-channel femtocells (2009)

The growing interest for high data rate wireless communications over the last few decades gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity of frequency spectrum has been forcing wireless system designers to develop methods that will push the spectral efficiency to its limit. One such method is to have multiple systems utilize the same spectrum by allowing some unavoidable interference to occur between them. The idea of co-channel systems is tested in the industrial, scientific and medical (ISM) bands and it is found to be a very beneficial approach. Therefore, it can be foreseen that co-channel systems might be a potential solution to the growing spectral crowding problem. 
Besides the systems that are designed to be co-channel, it is sometimes also possible to encounter that multiple systems occupy the same band undesirably. This kind of unintentional co-channel system scenarios might occur especially due to the dense re-use of available frequency bands. Another reason for unwanted co-channel usage might be the coexistence of third generation (3G) and fourth generation (4G) systems. Since 4G systems will probably be targeting to use the same frequency bands as their 3G counterparts, and since the transition from 3G to 4G will take some time, unintentional co-channel scenarios might be observed between the 3G and 4G systems. 
This dissertation consists of baseband receiver algorithms for OFDMA-based systems that target at handling the potential co-channel interference (CCI) in various co-channel system scenarios. Three CCI avoidance and two CCI cancellation algorithms are proposed that can be applied to intentional and unintentional co-channel systems. Femtocells, which have recently been introduced as a new class of personal-use base stations that can coexist with macrocell networks in a shared spectrum manner, might constitute an appropriate example for both types of co-channel systems. Therefore, they are considered to be one of the co-existing systems in most of the algorithms presented.
Aerodynamic Design of a Dual-Flow Mach 7 Hypersonic Inlet System for a Turbine-Based Combined-Cycle Hypersonic Propulsion System (2008)

A new hypersonic inlet for a turbine-based combined-cycle (TBCC) engine has been designed. This split-flow inlet is designed to provide flow to an over-under propulsion system with turbofan and dual-mode scramjet engines for flight from takeoff to Mach 7. It utilizes a variable-geometry ramp, high-speed cowl lip rotation, and a rotating low-speed cowl that serves as a splitter to divide the flow between the low-speed turbofan and the high-speed scramjet and to isolate the turbofan at high Mach numbers. The low-speed inlet was designed for Mach 4, the maximum mode transition Mach number. Integration of the Mach 4 inlet into the Mach 7 inlet imposed significant constraints on the low-speed inlet design, including a large amount of internal compression. The inlet design was used to develop mechanical designs for two inlet mode transition test models: small-scale (IMX) and large-scale (LIMX) research models. The large-scale model is designed to facilitate multi-phase testing including inlet mode transition and inlet performance assessment, controls development, and integrated systems testing with turbofan and scramjet engines.
Viral hepatitis prevalence in patients with active and latent tuberculosis (2015)

Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV.
Adversarial memory for detecting destructive races (2010)

Multithreaded programs are notoriously prone to race conditions, a problem exacerbated by the widespread adoption of multi-core processors with complex memory models and cache coherence protocols. Much prior work has focused on static and dynamic analyses for race detection, but these algorithms typically are unable to distinguish destructive races that cause erroneous behavior from benign races that do not. Performing this classification manually is difficult, time consuming, and error prone.
CLINICAL—LIVER, PANCREAS, AND BILIARY TRACT Aging of Hepatitis C Virus (HCV)-Infected Persons in the United States: A Multiple Cohort Model of HCV Prevalence and Disease Progression (2010)

BACKGROUND & AIMS: The prevalence of chronic hepatitis C (CH-C) remains high and the complications of infection are common. Our goal was to project the future prevalence of CH-C and its complications. METHODS: We developed a multicohort natural history model to overcome limitations of previous models for predicting disease outcomes and benefits of therapy. RESULTS: Prevalence of CH-C peaked in 2001 at 3.6 million. Fibrosis progression was inversely related to age at infection, so cirrhosis and its complications were most common after the age of 60 years, regardless of when infection occurred. The proportion of CH-C with cirrhosis is projected to reach 25% in 2010 and 45% in 2030, although the total number with cirrhosis will peak at 1.0 million (30.5% higher than the current level) in 2020 and then decline. Hepatic decompensation and liver cancer will continue to increase for another 10 to 13 years. Treatment of all infected patients in 2010 could reduce risk of cirrhosis, decompensation, cancer, and liver-related deaths by 16%, 42%, 31%, and 36% by 2020, given current response rates to antiviral therapy. CONCLUSIONS: Prevalence of hepatitis C cirrhosis and its complications will continue to increase through the next decade and will mostly affect those older than 60 years of age. Current treatment patterns will have little effect on these complications, but wider application of antiviral treatment and better responses with new agents could significantly reduce the impact of this disease in coming years.

Numerical Optimal Control Strategies for Semi-Active Vehicle Suspension with Electrorheological Fluid Dampers (2001)

Optimal control problems for semi-active vehicle suspensions and their numerical solution are discussed in this paper. For this purpose, several models of the vehicle dynamics with different levels of details and a general formulation of different sub-criteria for rating the ride comfort and safty are presented and investigated in this paper. The benefits and drawbacks of various numerical optimal control methods such as LQR-, H∞ and direct collocation when applied to the different optimal control problems for semi-active vehicle suspension are investigated. Furthermore, the semi-active vehicle suspension is based on a dynamic model of the recently developed prototype of a continuously controllable shock absorber with a smart, electrorheological fluid. These are smart materials and have been known for already more than 50 years. They belong to the group of colloidal suspensions which are able to change their viscosity drastically. This depends upon molecular chain formations in the fluid caused by an electric field perpendicular to the direction of flow. Very low control costs and fast response times of the ERF devices have sparked much an interest in ERFs in the last couple of years. The development of new control strategies for ERF devices integrated into complex multi body systems require a high level of knowledge of the behavior of the ERF subsystems. Dynamic models of controllable ERF devices are studied with respect to their particular dependencies, effects and requirements. An application is presented here which merges linear optimal control strategies and ERF shock absorbers within a complex model of full car dynamics. Here we give a mathematical formulation for the objectives of ride comfort and safety that takes into account various measurement possibilities. The result demonstrates the large potential of optimally controlled ERF devices.

Design, Construction, and Analysis of a Large-Scale Inner Stator Radial Flux Magnetically Geared Generator for Wave Energy Conversion (2018)

A magnetically geared machine (MGM) integrates a magnetic gear with a low-torque, high-speed electric machine to create a single compact high-torque, low-speed device with the size advantages of a mechanically geared system and the reliability of a direct drive machine. This work investigates the use of MGMs for wave energy conversion through the development of a large-scale magnetically decoupled inner stator radial flux magnetically geared generator rated for 10 kW at an input speed of 30 r/min. Critical design trends are illustrated using parametric two-dimensional and three-dimensional finite element simulation results. Information is also provided about the prototype's mechanical structure and key magneto-mechanical design considerations, including the impact of modulator bridges and the extent of axially escaping leakage flux. The prototype's experimental stall torque of 3870 Nm represents a 99.1% match with the simulated stall torque and corresponds to volumetric and gravimetric torque densities of 82.8 kNm/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and 14.5 Nm/kg, respectively. Additionally, the prototype achieves an experimental efficiency of approximately 90% for operation near rated torque.
Enhanced fluctuations in radiation scattered by a moving random phase screen (1976)

We discuss the properties of enhanced non-Gaussian fluctuations that occur in radiation scattered by a moving deep random phase screen (e.g., a perfectly conducting, very rough surface) when the scattering configuration is such that the electric field at the point of observation is composed of relatively few independent randomly phased contributions. Fraunhofer and Fresnel region effects are considered both from the information-content point of view and in the context of unwanted noise in measuring and detection systems.
IFN-γ Is Produced by Polymorphonuclear Neutrophils in Human Uterine Endometrium and by Cultured Peripheral Blood Polymorphonuclear Neutrophils (1998)

Abstract Cytokines present in the human uterus play an important role both in modulating immune responses to infectious challenge and in the establishment and maintenance of pregnancy. In particular, successful implantation and pregnancy is thought to require the establishment of a Th2 environment, while Th1 cytokines are associated with pregnancy loss and infertility. On the other hand, a Th1 response appears to be required for the resolution of acute infection. Using novel confocal microscopic analysis of fresh sections of human tissue, we have investigated the production of IFN-γ, a Th1 cytokine, in human endometria. Extracellular IFN-γ, mostly associated with matrix components, was located immediately beneath the luminal epithelium and along the glandular epithelium proximal to the lumen. As evidenced by intracellular staining, IFN-γ is produced by both stromal cells and intraepithelial lymphocytes through all stages of the menstrual cycle. Surprisingly, the stromal cell containing intracellular IFN-γ was identified as a polymorphonuclear neutrophil on the basis of its reactivity with a panel of mAbs and its nuclear morphology. We further found that polymorphonuclear neutrophils isolated from normal donors produce IFN-γ in response to stimulation with LPS, IL-12, and TNF-α. Taken together, these findings suggest that polymorphonuclear neutrophils are capable of producing IFN-γ both in vitro and in vivo, indicating that their role in shaping immune responses may be more extensive than previously thought. Furthermore, these studies strongly suggest that polymorphonuclear neutrophils play an important role in determining immune responsiveness within the female reproductive tract.
On the stability of Poiseuille flow of a Bingham fluid (1994)

The stability to linearized two-dimensional disturbances of plane Poiseuille flow of a Bingham fluid is considered. Bingham fluids exhibit a yield stress in addition to a plastic viscosity and this description is typically applied to drilling muds. A non-zero yield stress results in an additional parameter, a Bingham number, and it is found that the minimum Reynolds number for linear instability increases almost linearly with increasing Bingham number.
The IGF system in Chickens: Factors Affecting Gene Expression in Muscle and Liver (2006)

Age and dietary protein supply control muscle growth directly and indirectly through the influence of regulatory factors. Insulin‐like growth factors (IGF1 and 2) and IGF binding proteins (IGFBP) are key regulators of muscle development and metabolism in birds and other vertebrate species. Gene expression of IGF1 and 2, IGF receptor, and IGFBP 1,2,4 and 5 in the liver, pectoralis major (PM), and vastus lateralis muscles (VL) from broiler chickens were determined by Real Time PCR. In an age study, tissue was collected from chickens at 7 (D7) and 35 (D35) days‐of‐age fed a 24% protein diet. An additional two groups of chickens were fed either 12% (P12) or 30% (P30) dietary protein after 7 days‐of‐age, and samples were collected at D39. Plasma IGF1 was 2‐fold higher on D35 than D7. Hepatic IGF1, IGFBP1, and IGFBP4 gene expressions were significantly higher at D35 than D7. At D7, PM IGFBP4 and VL IGF2 were expressed greater than at D35. In the dietary protein study, chickens fed P30 had higher plasma IGF1. In this group (P30) body, fat, and lean tissue weights, bone mineral density and bone mineral content were 2.5‐fold greater than P12. However, hepatic IGF1, IGFBP1 and IGFBP5 mRNA expression levels were higher in P12 than P30. In PM, IGFBP4 gene expression was greater in the chicks fed 30% dietary protein. VL muscle IGF receptor gene expression was greater in the chickens fed P30 than P12. These data demonstrate that IGF and IGFBP gene expression are influenced by age and dietary protein in the chicken.
INTORNO ALLA CAUTIO MUCIANA APPLICATA ALL' EREDITA (1948)

Lo Scialoia appena all' inizio del dilagare della critica delle fonti, concludeva che probabilmente nel diritto classico la cautio Muciana non fosse applicabile all' eredita.  Questa conclusione, ripetuta nei nostri manuali data l' autorita del Maestro, e ignorata dal Levy, ma accolta da H. Krueger, i soli autori moderni che si siano occupati ex professo del nostro istituto; e ignorata anche in parecchie esposizioni, che pur trattano dell' argomento, mentre in altre quella conclusione e prospettata come probabile o non esclusa.
Methanogenesis in Big Soda Lake, Nevada: an Alkaline, Moderately Hypersaline Desert Lake (1982)

Incubated sediment slurries from Big Soda Lake, Nevada, produced significant levels of CH(4), and production was inhibited by 2-bromoethanesulfonic acid and by autoclaving. Methane production was stimulated by methanol, trimethylamine, and, to a lesser extent, methionine. Surprisingly, hydrogen, acetate, and formate amendments provided only slight or no stimulation of methanogenesis. Methane production by sediment slurries had a pH optimum of 9.7. A methanol-grown enrichment culture containing a small, epifluorescent coccus as the predominant organism was recovered from sediments. The enrichment grew best when FeS or autoclaved sediment particles were included in the media, had a pH optimum of 9.7, and produced CH(4) from CH(3)OH. The methane formed by methanolgrown enrichment cultures was depleted in C by 72 to 77 per thousand relative to the methanol.
Specifying and dynamically verifying address translation-aware memory consistency (2010)

Computer systems with virtual memory are susceptible to design bugs and runtime faults in their address translation (AT) systems. Detecting bugs and faults requires a clear specification of correct behavior. To address this need, we develop a framework for AT-aware memory consistency models. We expand and divide memory consistency into the physical address memory consistency (PAMC) model that defines the behavior of operations on physical addresses and the virtual address memory consistency (VAMC) model that defines the behavior of operations on virtual addresses. As part of this expansion, we show what AT features are required to bridge the gap between PAMC and VAMC. Based on our AT-aware memory consistency specifications, we design efficient dynamic verification hardware that can detect violations of VAMC and thus detect the effects of design bugs and runtime faults, including most AT related bugs in published errata.
Closed Complex Dorsal Dislocation of the Middle Finger Metacarpophalangeal Joint (1988)

A rare complex isolated metacarpophalangeal joint dislocation of the middle finger is described, and the pathology is reviewed. The dorsal longitudinal incision used in this case provided excellent exposure for the reduction and helped avoid injury to the digital nerves on the palmar side of the injury. Early mobilization with extension blocking is advocated to maximize joint range of motion postoperatively.
On the Expressive Power of Some Extensions of Linear Temporal Logic (2019)

One of the most simple models of computation suitable for representation of reactive systems behavior is a finite state transducer that operates on an input alphabet of control signals and an output alphabet of basic actions. The behavior of such a reactive system displays itself in the correspondence between the flow of control signals and sequence of basic actions performed by the system. We believe that the behavior of this kind requires more complex and expressive means of specifications than the conventional linear temporal logic ($$LTL$$). In this paper, we define a new language of formal specifications $$\mathcal{L}\mathcal{P}$$-$$LTL$$, which is an extension of LTL, specifically intended for describing the properties of transducer computations. In this extension, the temporal operators are parameterized by sets of words (languages) which describe flows of control signals that impact on a reactive system. Basic predicates in the ℒ𝒫-LTL formulas are also defined by the languages in the alphabet of basic actions; these languages describe the expected response of the system to the environmental influences. In our earlier papers, we considered a verification problem for finite state transducers with regard to specifications represented by the ℒ𝒫-$$LTL$$ and ℒ𝒫-$$CTL$$ formulas. It was shown that the problem is algorithmically solvable for both logics. The aim of this paper is to estimate the expressive power of ℒ𝒫-$$LTL$$ by comparing it with some well-known logics widely used in computer science for specification of reactive systems. Two fragments were isolated in the ℒ𝒫-LTL: ℒ𝒫-1-LTL and ℒ𝒫-n-LTL. We discovered that the specification language of ℒ𝒫-1-$$LTL$$ is more expressive than LTL, while the ℒ𝒫-n-$$LTL$$ fragment has the same expressive power as the monadic second order logic S1S. temporal logics, expressive power, specification, verification, Büchi automata, infinite words
Cu<sup>II</sup> Coordination Chemistry of Patellamide Derivatives: Possible Biological Functions of Cyclic Pseudopeptides (2012)

Two synthetic derivatives of the naturally occurring cyclic pseudooctapeptides patellamide A-F and ascidiacyclamide, that is, H(4)pat(2), H(4)pat(3), as well as their Cu(II) complexes are described. These cyclic peptide derivatives differ from the naturally occurring macrocycles by the variation of the incorporated heterocyclic donor groups and the configuration of the amino acids connecting the heterocycles. The exchange of the oxazoline and thiazole groups by dimethylimidazoles or methyloxazoles leads to more rigid macrocycles, and the changes in the configuration of the side chains leads to significant differences in the folding of the cyclic peptides. These variations allow a detailed study of the various possible structural changes on the chemistry of the Cu(II) complexes formed. The coordination of Cu(II) with these macrocyclic species was monitored by high-resolution electrospray mass spectrometry (ESI-MS), spectrophotometric (UV/Vis) and circular dichroic (CD) titrations, and electron paramagnetic resonance (EPR) spectroscopy. Density functional theory (DFT) calculations and molecular mechanics (MM) simulations have been used to model the structures of the Cu(II) complexes and provide a detailed understanding of their geometric preferences and conformational flexibility. This is related to the Cu(II) coordination chemistry and the reactivity of the dinuclear Cu(II) complexes towards CO(2) fixation. The variation observed between the natural and various synthetic peptide systems enables conclusions about structure-reactivity correlations, and our results also provide information on why nature might have chosen oxazolines and thiazoles as incorporated heterocycles.
Pallidotomy and bradykinesia (1998)

Despite the clinical efficacy of pallidotomy while patients were "off," bradykinesia of elbow flexion movements while patients were "on" is not affected by pallidotomy. Therefore, we conclude that the bradykinesia observed in this experiment is due to a mechanism other than excessive tonic inhibition of the motor thalamus. Our results are consistent with the idea that pallidotomy reduces the noise from the abnormally functioning basal ganglia.
