Crystal Structure of the Rac1−RhoGDI Complex Involved in NADPH Oxidase Activation<sup>,</sup> (2001)

A heterodimer of prenylated Rac1 and Rho GDP dissociation inhibitor was purified and found to be competent in NADPH oxidase activation. Small angle neutron scattering experiments confirmed a 1:1 stoichiometry. The crystal structure of the Rac1-RhoGDI complex was determined at 2.7 A resolution. In this complex in which Rac1 is bound to GDP, the switch I region of Rac1 is in the GDP conformation whereas the switch II region resembles that of a GTP-bound GTPase. Two types of interaction between RhoGTPases and RhoGDI were investigated. The lipid-protein interaction between the geranylgeranyl moiety of Rac1 and RhoGDI resulted in numerous structural changes in the core of RhoGDI. The interactions between Rac1 and RhoGDI occur through hydrogen bonds which involve a number of residues of Rac1, namely, Tyr64(Rac), Arg66(Rac), His103(Rac), and His104(Rac), conserved within the Rho family and localized in the switch II region or in its close neighborhood. Moreover, in the switch II region of Rac1, hydrophobic interactions involving Leu67(Rac) and Leu70(Rac) contribute to the stability of the Rac1-RhoGDI complex. Inhibition of the GDP-GTP exchange in Rac1 upon binding to RhoGDI partly results from interaction of Thr35(Rac) with Asp45(GDI). In the Rac1-RhoGDI complex, the accessibility of the effector loops of Rac1 probably accounts for the ability of the Rac1-RhoGDI complex to activate the NADPH oxidase.
Properties of High-Resistivity Gallium Arsenide Compensated with Diffused Copper (1961)

Low-resistivity n-type GaAs crystals with silicon donors are compensated with diffused copper to produce high-resistivity crystals in a manner which is amenable to semiquantitative description in terms of a simple thermodynamic model. The high-resistivity GaAs:Cu crystals are subjected to photoelectronic analysis, including room temperature Hall and photo-Hall measurements, to obtain information about the effects of deep-lying imperfections on the properties of the initial n-type GaAs. In addition to three deep donors previously reported, five acceptors are revealed. A 0.42-ev acceptor level, when compensated, provides a long electron lifetime resulting in high n-type photosensitivity at low temperatures. Evidence for effects on the electron mobility is obtained for compensated deep donor levels, important mainly in high-resistivity n-type material, and for compensated acceptors lying 0.22 ev above the valence band, important mainly at low temperatures.
The Volcker Commission Report Fades Away: A Case Study in Non‐implementation (1993)

The National Commission on the Public Service, commonly known as the Volcker Commission, was created to help combat a ‘quiet crisis’ in the United States' federal civil service. The commission made a series of recommendations to strengthen the civil service. With few exceptions, these recommendations have not made their way into law. This examination of the work of the task forces on education and training and on recruitment and retention, in the framework of Daniel Mazmanian and Paul Sabatier's implementation model, focuses on what happened to the Volcker report and why it happened. It concludes with recommendations on what might be done differently in future efforts to strengthen the civil service.

Imatran Voima Oy (IVO) is developing an advanced gas turbine power plant process for wet fuels as peat, biomass, and lignite. The process consists of a steam injected gas turbine, an air blown gasifier and a pressurized fuel dryer. The dryer operates at steam atmosphere and is integrated to the process to produce injection steam for the gas turbine. The heat needed for drying is taken from the exhaust gases of the gas turbine. The process is patented and called IVOSDIG.
Exhaled markers of inflammation (2001)

Exhaled markers of inflammation allow completely noninvasive monitoring of inflammation and oxidative stress in the respiratory tract in inflammatory lung diseases, including asthma, chronic obstructive pulmonary disease, cystic fibrosis, bronchiectasis and interstitial lung diseases. Such noninvasive techniques are simple to perform, may be repeated frequently and can be applied in children, including neonates and patients with severe disease in whom more invasive procedures are not possible. Several volatile chemicals can be measured in the breath (nitric oxide, carbon monoxide, hydrocarbons), and many nonvolatile molecules (mediators, oxidation and nitration products, proteins) may be measured in exhaled breath condensate.

THE EFFECTS OF SURFACTANTS ON CRYSTALLIZATION PHENOMENA (1993)

ABSTRACT Crystallization phenomena and processes may be greatly affected by the addition of surfactants, which play an important rote in nucleation and growth kinetics and can substantially modify both habit and size distribution of crystal products. Moreover, scaling in industrial equipments and caking in storage tanks can be reduced and re-dissolution more easily accomplished. All these effects are related to adsorption of surfactant molecules onto crystal faces. Other applications of surfactants in crystallization processes involve nucleation induced by amphiphilic films, and micelle or microemulsion solubilization of nuclei. The above aspects are thoroughly reviewed through literature data.
Cardiovascular Complications of Human Immunodeficiency Virus Infection (2006)

The heart and great vessels are not the sites most frequently affected by opportunistic infections and neoplastic processes in patients with acquired immune deficiency syndrome (AIDS). However, cardiovascular complications occur in a significant number of such patients and are the immediate cause of death in some. The spectrum of cardiovascular complications of AIDS that may be depicted at imaging includes dilated cardiomyopathy, pericardial effusion, human immunodeficiency virus-associated pulmonary hypertension, endocarditis, thrombosis, embolism, vasculitis, coronary artery disease, aneurysm, and cardiac involvement in AIDS-related tumors. To aid accurate diagnosis and appropriate treatment planning, radiologists should be familiar with the imaging appearance of each of these complications.
Fast solvers and efficient implementations for distance metric learning (2008)

In this paper we study how to improve nearest neighbor classification by learning a Mahalanobis distance metric.We build on a recently proposed framework for distance metric learning known as large margin nearest neighbor (LMNN) classification.Our paper makes three contributions.First, we describe a highly efficient solver for the particular instance of semidefinite programming that arises in LMNN classification; our solver can handle problems with billions of large margin constraints in a few hours.Second, we show how to reduce both training and testing times using metric ball trees; the speedups from ball trees are further magnified by learning low dimensional representations of the input space.Third, we show how to learn different Mahalanobis distance metrics in different parts of the input space.For large data sets, the use of locally adaptive distance metrics leads to even lower error rates.
Electron energy distribution function measurements in a planar inductive oxygen radio frequency glow discharge (1993)

A tuned, cylindrical Langmuir probe was used to measure current-voltage traces in a planar, inductive oxygen, radio frequency glow discharge at several pressures ranging from 0.5 to 10 mT. The plasma potentials were determined from the zero crossings of the trace second derivatives. Positive ion densities were evaluated using orbit motion limited probe theory; electron densities were estimated by integrating the area under the unnormalized distribution function. By applying the Druyvesteyn formula to the digitized probe traces, the electron energy distribution functions were obtained. The distribution functions ranged from Maxwellian at 0.5 mT to almost Druyvesteyn-like at 10 mT.
Linear Couplers for Bus Protection (1942)

A scheme of bus protection offering advantages in simplicity, speed, and size uses linear couplers (air-core mutual reactances) in place of current transformers. This solves the troublesome problem of saturation and provides a linear relationship between secondary voltage and primary current. The coupler secondaries for a given bus are connected in a series loop with the relay. When the currents entering and leaving the bus are equal, the net induced voltage in the relay loop is zero. For a fault on the bus, however, the net induced voltage, proportional to the fault current, operates the relay. The problems are: 1. To utilize effectively the smaller available energy. 2. To build couplers of sufficiently equal mutual reactance and unaffected by stray fields. A toroidal coil solved the latter problem. Through tests have shown that the performance is strictly linear with respect to primary currnet, practically unaffected by the primary d-c transient, and thus can be calculated accurately and simply.

Major results included the definition of the 1988 general aviation market, the identification of turboprop and turboshaft engines that meet the requirements of the aircraft studies, a benefit analysis showing the superiority of gas turbine engines for portions of the market studied, and detailed plans for the development of the necessary technology.
A practical three‐dimensional dosimetry system for radiation therapy (2006)

There is a pressing need for a practical three-dimensional (3D) dosimetry system, convenient for clinical use, and with the accuracy and resolution to enable comprehensive verification of the complex dose distributions typical of modern radiation therapy. Here we introduce a dosimetry system that can achieve this challenge, consisting of a radiochromic dosimeter (PRESAGE) and a commercial optical computed tomography (CT) scanning system (OCTOPUS). PRESAGE is a transparent material with compelling properties for dosimetry, including insensitivity of the dose response to atmospheric exposure, a solid texture negating the need for an external container (reducing edge effects), and amenability to accurate optical CT scanning due to radiochromic optical contrast as opposed to light-scattering contrast. An evaluation of the performance and viability of the PRESAGE/OCTOPUS, combination for routine clinical 3D dosimetry is presented. The performance of the two components (scanner and dosimeter) was investigated separately prior to full system test. The optical CT scanner has a spatial resolution of < or = 1 mm, geometric accuracy within 1 mm, and high reconstruction linearity (with a R2 value of 0.9979 and a standard error of estimation of approximately 1%) relative to independent measurement. The overall performance of the PRESAGE/OCTOPUS system was evaluated with respect to a simple known 3D dose distribution, by comparison with GAFCHROMIC EBT film and the calculated dose from a commissioned planning system. The "measured" dose distribution in a cylindrical PRESAGE dosimeter (16 cm diameter and 11 cm height) was determined by optical-CT, using a filtered backprojection reconstruction algorithm. A three-way Gamma map comparison (4% dose difference and 4 mm distance to agreement), between the PRESAGE, EBT and calculated dose distributions, showed full agreement in measurable region of PRESAGE dosimeter (approximately 90% of radius). The EBT and PRESAGE distributions agreed more closely with each other than with the calculated plan, consistent with penumbral blurring in the planning data which was acquired with an ion chamber. In summary, our results support the conclusion that the PRESAGE optical-CT combination represents a significant step forward in 3D dosimetry, and provides a robust, clinically effective and viable high-resolution relative 3D dosimetry system for radiation therapy.
Predictive Factors in Chronic Graft-Versus-Host Disease in Patients with Aplastic Anemia Treated by Marrow Transplantation from HLA-Identical Siblings (1983)

One hundred ten of 175 patients with aplastic anemia conditioned by cyclophosphamide had sustained engraftment of marrow from human leukocyte antigen (HLA)-identical siblings and lived for more than 6 months. Forty-nine of the 110 patients developed chronic graft-versus-host disease between 85 and 464 days. Ninety-seven patients are alive from 1.4 to 11 years after engraftment; 13 died between 208 and 726 days. Twenty of the 36 surviving patients with chronic graft-versus-host disease have Karnofsky performance scores of 100%, 7 of 90%, 5 of 80%, 1 of 70%, 2 of 60%, and 1 of 40%. Our analysis, using a binary logistic regression model, identified three factors predicting chronic graft-versus-host disease: moderate to severe acute graft-versus-host disease with an estimated relative risk of 11.65; increasing patient age; and the use of viable donor buffy coat cells in addition to the marrow to prevent graft rejection. The last two factors were significant only in patients without acute graft-versus-host disease.
A simulation-based algorithm for supply chain optimization (2007)

In a supply chain, there are wide variety of problems, such as transportation scheduling problems and warehouse location problems. These problems are independently defined as optimization problems, and algorithms have been proposed for each problem. It is difficult, however, to design an algorithm for optimizing a supply chain simultaneously because the problem is much more complex than the individual problems. We present a simulation-based optimization algorithm that optimizes a supply chain, exploiting both simulation and optimization techniques. This system leverages two existing algorithms, and will optimize a supply chain by executing simulations while changing the boundary conditions between the two algorithms. Experimental results show that a better solution to a supply chain can be found through a series of optimization simulations. A logistics consultant was satisfied with the solution. This system will be used in actual logistics consulting services.
Marine natural products as sources of antiviral, antimicrobial, and antineoplastic agents (1981)

Abstract
Average power reduction techniques for multiple-subcarrier intensity-modulated optical signals (2002)

We describe two classes of simple, effective techniques for reducing the average optical power requirement in intensity-modulated optical systems using multiple BPSK or QPSK subcarriers. The first class of techniques involves block coding between the information bits to be transmitted and the symbol amplitudes modulated onto the subcarriers, in order to increase the minimum value of the multiple-subcarrier electrical waveform. The second class of techniques involves replacing the fixed d.c. bias by a bias signal that varies on a symbol-by-symbol basis. These two classes of techniques can be applied separately or in tandem. The reduction in power requirement increases with the number of subcarriers, and with eight subcarriers, can be as high as about 3.6 dB and 3.2 dB with BPSK and QPSK, respectively. The techniques described are applicable as long as all subcarriers originate from a single transmitter and are symbol-synchronized.
A simulation-based JTAG ATPG optimized for MCMS (2002)

Boundary scan test generation tools generate tests based on the netlist of the design. Netlist-based tools are very efficient in designs with a high percentage of boundary scan devices, but can be inefficient in designs containing a significant percentage of non-compatible ICs. An alternative method, in which the user defines the nets to test, is explored.
In vitro and in vivo activities of T4 endonuclease V mutants altered in the C-terminal aromatic region (1990)

Genes encoding mutants of the thymine photodimer repair enzyme from bacteriophage T4 (T4 endonuclease V) having an amino acid substitution (T127M, W128A, W128S, Y129A, K130L, Y131A, Y132A) were constructed by use of a previously obtained synthetic gene and expressed in Escherichia coli under the control of the E. coli tryptophan promoter. An in vitro assay of partially fractionated mutant proteins for glycosylase activity was performed with chemically synthesized substrates containing a thymine photodimer. T127M and K130L showed almost the same activity as the wild-type protein. Although W128S, Y131A, and Y132A were slightly active, W128A and Y129A lost activity. The results indicated that the aromatic amino acids around position 130 may be important for the glycosylase activity. Mutant T127M was purified, and the Km value was found to be of the same order as that of the wild type (10(-8) M). In vivo activities for all mutants were characterized with UV-sensitive E. coli. The results showed that substitution of Thr-127 with Met or Lys-130 with Leu did not have an effect on the survival of the bacteria but substitution of aromatic amino acids (128-132) had various effects on survival.

Mechanistic Studies of the Cycloisomerization of Dimethyl Diallylmalonate Catalyzed by a Cationic Palladium Phenanthroline Complex (2001)

The mechanism of the cycloisomerization of dimethyl diallylmalonate (1) catalyzed by the cationic palladium phenanthroline complex [(phen)Pd(Me)CNCH(3)](+)[BAr(4)](-) [Ar = 3,5-C(6)H(3)(CF(3))(2)] (2) has been investigated. Heating a solution of 1 and 2 (5 mol %) in DCE at 40 degrees C led to zero-order decay of 1 to approximately 80% conversion (k(obs) = (7.1 +/- 0.3) x 10(-7) M s(-1)) with formation of a 27:2.2:1.0 mixture of 3,3-bis(carbomethoxy)-1,5-dimethylcyclopentene (3), 4,4-bis(carbomethoxy)-1,2-dimethylcyclopentene (4), and 1,1-bis(carbomethoxy)-4-methyl-3-methylenecyclopentane (5) and traces ( approximately 3.5%) of ethyl-substituted carbocycles 6 of the chemical formula C(12)H(18)O(4). Cyclopentenes 3 and 4 were formed both kinetically (3:4 = 30:1 at 40 degrees C) and via secondary isomerization of 5 (3:4 = 1:2.5 at 40 degrees C); the kinetic pathway accounted for the 93% of cyclopentene formation at 40 degrees C. Carbocycles 6 were formed predominantly (> or =90%) within the first two catalyst turnovers as byproducts of catalyst activation. Stoichiometric reaction of 1 and 2 at room temperature for 1.5 h led to the isolation of the palladium cyclopentyl chelate complex [carbohydrate structure-see text] in 26% yield as a approximately 2:1 mixture of isomers. The structure of trans,trans-7 was determined by X-ray crystallography. Kinetic studies of the formation of 7 established the rate law: rate = k[1][2], where k = (2.1 +/- 0.3) x 10(-2) M(-1) s(-1) (Delta G(*)(298K) = 19.7 +/- 0.1 kcal mol(-1)) at 25 degrees C. Thermolysis of 7 at 50 degrees C formed carbocycles 6 in 65% yield by GC analysis. (1)H and (13)C NMR analysis of an active catalyst system generated from 1 and a catalytic amount of 2 led to the identification of the cyclopentyl chelate complex [carbohydrate structure-see text] as the catalyst resting state. Cycloisomerization of 1-2,6-d(2) formed predominantly (approximately 90%) 3,3-bis(carbomethoxy)-5-deuterio-1-(deuteriomethyl)-5-methylcyclopentene (3-d(2)); no significant (< or =10%) kinetic isotope effect or intermolecular H/D exchange was observed. Cycloisomerization of 1-3,3,5,5-d(4) formed a 1:2.6 mixture of 3,3-bis(carbomethoxy)-2,4,4-trideuterio-1,5-dimethylcyclopentene (3-d(3)) and 3,3-bis(carbomethoxy)-2,4,4-trideuterio-5-(deuteriomethyl)-1-methylcyclo pentene (3-d(4)); while no significant (< or =10%) kinetic isotope effect was detected, extensive intermolecular H/D exchange was observed. These data are consistent with a mechanism involving hydrometalation of an olefin of 1, intramolecular carbometalation, isomerization via reversible beta-hydride elimination/addition, and turnover-limiting displacement of the cyclopentenes from palladium.
