Immunoreactive kallikrein localization in the rat kidney: an immuno-electron-microscopic study. (1984)

The cellular and subcellular localization of immunoreactive kallikrein was studied in the rat kidney using the peroxidase-antiperoxidase (PAP) method for the electron microscope. The effect of various tissue-processing protocols on ultrastructural preservation and immunocytochemical staining was evaluated by fixing kidneys with four different mixtures. The tissues were immunostained and further stained with OsO4 or silver methenamine. The best ultrastructural and immunocytochemical staining was obtained with Zamboni's-glutaraldehyde fixative. The kallikrein-immunoreactive cell type was identified, according to its localization and ultrastructural features, as the connecting-tubule cell. Immunoreactive kallikrein was concentrated mainly in the upper one-third of the cell and at both sides of the nuclei, and to a less extent was associated with the plasma membranes and basolateral infoldings. The immunoreactivity was related to free polyribosomes, the rough endoplasmic reticulum (RER), and the Golgi complex, suggesting that kallikrein is actively synthesized in this particular type of cell.
Phase Shift by Periodic Loading of Waveguide and Its Application to Broad-Band Circular Polarization (1955)

A rectangular or square waveguide may be loaded periodically by thin capacitive or inductive irises in order to produce phase delay or phase advance, respectively. The amount of phase shift may be calculated with accuracy by making use of available theoretical values of iris susceptance and of transmission line theory. The phase shifting sections maybe designed for low voltage standing-wave ratio (vswr) over a considerable bandwidth. When a square waveguide capable of supporting two fundamental modes is loaded periodically, the irises act inductively for one mode and capacitively for the other, thus introducing a differential phase shift. This differential phase shift may be made equal to 90°, in order to convert linear to circular polarization. Furthermore such a device may be made, by proper choice of parameters, to yield near-circular polarization over a bandwidth of 1.65:1, because the variation in phase delay for one mode and phase advance for the other tend to compensate each other as the frequency is varied. Several of these circular polarizers have been built and tested at X band and the measured results of ellipticity and vswr, as well as broad-band performance check with theoretical values quite closely.

A Study on the Design of Wells Turbine for Wave Power Conversion by Various Flap Shape (1) (2004)

A numerical investigation was performed to determine the effect of airfoil on the optimum flap height using NACA0015 Wells turbine. The five double flaps which have 0.5% difference were selected. A Navier-Stokes code, CFX-TASCflow, was used to calculate the flow field of the Wells turbine. The basic feature of the Wells turbine is that even though the cyclic airflow produces oscillating axial forces on the airfoil blades, the tangential force on the rotor is always in the same direction. Geometry used to define the three dimension numerical grid is based upon that of an experimental test rig. This paper tries In optimized disign the double flap of Wells turbine with the numerical analysis.
I Might be Fundamentally Mistaken (2017)

Quasi-realism aspires to preserve the intelligibility of the realist-sounding moral judgments of ordinary people. These judgments include ones of the form, “I believe that p, but I might be mistaken,” where “p” is some moral content. The orthodox quasi-realist strategy (famously developed by Simon Blackburn) is to understand these in terms of the agent’s worrying that some improving change would lead one to aban-don the relevant moral belief. However, it is unclear whether this strate-gy generalizes to cases in which the agent takes their error to be funda-mental in a sense articulated by Andy Egan. In an influential paper, Egan argues that it does not. Egan suggests that Blackburn’s approach is the only game in town for the quasi-realist when it comes to making sense of judgment of fallibility, and therefore concludes that Blackburn’s ina-bility to handle worries about fundamental moral error refutes quasi-realism tout court. Egan’s challenge has generated considerable discus-sion. However, in my view, we have not yet gotten to the heart of the matter. I argue that what is still needed is a fully general, quasi-realist-friendly theory of the nature of first-person judgments of fallibility, such that these judgments are demonstrably consistent with judging that the belief is stable in Egan’s sense. In this article, I develop and defend a fully general quasi-realist theory of such judgments, which meets this demand. With this theory in hand, I argue that Egan’s challenge can be met. Moreover, my discussion of how the challenge is best met provides an elegant diagnosis of where Egan’s argument against goes wrong. On my account, Egan’s argument equivocates at a key point between a “could” and a “would.”
Steering the Last Trailer as a Virtual Tractor for Reversing Vehicles With Passive On- and Off-Axle Hitches (2013)

The paper reports on a practical backward motion strategy for a vehicle pushing several passive trailers with any combination of on- and off-axle hitches. The last trailer is defined as a virtual tractor that can be guided along paths of varying curvature like a single non-holonomic vehicle. Then, kinematic relationships are proposed to translate the resulting motion commands to the actual tractor. The paper extends previous work by specifically addressing propagation of virtual set-points through on-axle hitches. This case is difficult because direct propagation cannot be achieved due to kinematic restrictions imposed by current joint angles. The method has been experimentally applied for both autonomous path-tracking and online operator steering using a tracked mobile robot with two different off- and on-axle combinations of dissimilar trailers. Results indicate applicability in autonomous vehicles and advanced driver assistance systems.
[Kimura's disease and angiolymphoid hyperplasia with eosinophilia-- on disease with different expressions?]. (1998)

Kimura's disease is a rare angiolymphoid proliferative disorder of soft tissue characterized by subcutaneous swelling and a predilection for the head and neck. There are usually enlarged regional lymph nodes, eosinophilia and elevated sedimentation rate and IgE levels. A 26-year-old women with subcutaneous masses in the submandibular area is reported. The diagnosis of Kimura's disease versus angiolymphoid hyperplasia is discussed.
Distribution and dynamic state of sterols and steroids in the tissues of an insect, the roach Eurycotis floridana (1966)

The total concentrations of sterols in the tissues of the roach, Eurycotis floridana, reared under aseptic conditions and on semisynthetic diets, are similar to, but somewhat lower than, those of tissues of vertebrates. Total concentrations of tissue sterols are relatively independent of dietary concentration of sterols whether the diet contains 0.1% cholesterol as the sole sterol, or a "minimal cholesterol" mixture (0.1% cholestanol together with 0.005% cholesterol). Under the latter conditions the cholesterol is incorporated preferentially into most tissues and remains almost exclusively unesterified, while the cholesterol-sparing sterol is esterified to varying degree, depending upon the tissue. The turnover of tissue sterols has been studied. Cholesterol of the tissues of adult insects grown on a diet containing this sterol alone may be displaced by cholestanol fed as 5% of the total diet, initially at an appreciable rate but later much less rapidly. In growing insects that have received a diet containing cholestanol together with minimal cholesterol, the unesterified cholesterol turns over slowly in all tissues and immeasurably slowly in some. The unesterified sparing sterol, on the other hand, turns over at a much greater rate. The turnover of sterols during growth is accompanied by a shift of sterols from the unesterified to the esterified pool in all tissues. The fat body of the growing insect stores sterols (apparently as their esters) that have been displaced from other tissues. The fat body of the adult does not show evidence of sterol storage. Polar derivatives of sterols are present in minor amount in all tissues of the insect, most abundantly in the mid-intestine and gastric caeca. These compounds seem likely to be C(27) steroids.
Fractal Geometries of Complementary Split-Ring Resonators (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Complementary split-ring resonators (CSRRs) are typically used as negative-permittivity particles in microstrip left-handed structures. In this paper, novel CSRRs that use a square Sierpinski fractal curve are proposed and studied in detail. It is shown that the application of fractal geometries results in significant miniaturization of the metamaterial unit cell in comparison with conventional and equivalent meander structures. Multiple fractal CSRRs are also analyzed. The influence of different geometrical parameters and the order of the fractal curve on the performances are investigated, as well as the efficiency of excitation of the particles. When used in the design of left-handed transmission lines, fractal complementary split rings improve frequency selectivity in the upper transition band when compared to other nonfractal topologies. </para>
Joint virtual machine placement and migration scheme for datacenters (2014)

Efficiently managing virtual machines (VMs) plays a key role in improving the resource usage and power consumption of datacenters. However, most of the existing techniques have been optimized for each system criterion separately (e.g., either platform layer or virtualization layer). Such approaches are simple to implement, but they usually result in poor system performance or under-utilization of the resources. In this paper, we investigate the problem of optimal VM management (i.e., placement and migration) in datacenters via a multi-objective function. We show that optimizing the proposed multi-objective function reduces not only the energy consumption, but also the cross network traffic among platforms. Due to the high complexity of the combinatorial optimization problem, we propose an efficient heuristic algorithm to find a near optimal solution based on the relaxed convex optimization framework. We provide both theoretical analysis and simulations to show the effectiveness of the proposed approach over the existing approaches.
Subspace identification of Hammerstein systems using least squares support vector machines (2005)

This paper presents a method for the identification of multiple-input-multiple-output (MIMO) Hammerstein systems for the goal of prediction. The method extends the numerical algorithms for subspace state space system identification (N4SID), mainly by rewriting the oblique projection in the N4SID algorithm as a set of componentwise least squares support vector machines (LS-SVMs) regression problems. The linear model and static nonlinearities follow from a low-rank approximation of a matrix obtained from this regression problem.
Secure Dynamic Memory Scheduling Against Timing Channel Attacks (2017)

This paper presents SecMC, a secure memory controller that provides efficient memory scheduling with a strong quantitative security guarantee against timing channel attacks. The first variant, named SecMC-NI, eliminates timing channels while allowing a tight memory schedule by interleaving memory requests that access different banks or ranks. Experimental results show that SecMC-NI significantly (45% on average) improves the performance of the best known scheme that does not rely on restricting memory placements. To further improve the performance, the paper proposes SecMC-Bound, which enables trading-off security for performance with a quantitative information theoretic bound on information leakage. The experimental results show that allowing small information leakage can yield significant performance improvements.
Constitutive expression of heat‐shock protein 70 in mammalian cells confers thermoresistance (1991)

A 70-kDa heat-shock-protein (hsp 70) expression vector which contains the human hsp 70 gene linked to the human beta-actin promoter, was constructed and used to transfect CV1 monkey cells. Stably transfected CV1 clones were isolated which constitutively synthesized increased amounts of hsp70 at normal temperature. It is shown that these clones are resistant to elevated temperature. This finding indicates that hsp70 is involved in the protection of the cells against a lethal heat treatment and maybe responsible for the phenomenon of thermotolerance.

Electrohydraulic Lithotripsy with Aspiration of the Fragments Under Vision—304 Consecutive Cases (1981)

We herein report on 304 consecutive cases of bladder stones treated by electrohydraulic lithotripsy. The special armamentarium is described. The average age for male patients was 68.5 years, the oldest being 102 years, and for female patients it was 63.9 years. Of the patients 38.5 per cent were high risk. The weight of the transurethrally removed stones ranged from 1 to 135 gm. In 70.4 per cent of the male patients transurethral resection of the prostate was done under the same anesthesia and technical problems were encountered in 12 operations (4 per cent). Bladder perforations occurred in 5 patients but cystotomy and drainage were necessary in only 1 (0.3 per cent).
Therapy with Plasma Purified Alpha1-Antitrypsin (Prolastin®) Induces Time-Dependent Changes in Plasma Levels of MMP-9 and MPO (2015)

The common Z mutation (Glu342Lys) of α1-antitrypsin (A1AT) results in the polymerization and intracellular retention of A1AT protein. The concomitant deficiency of functional A1AT predisposes PiZZ subjects to early onset emphysema. Clinical studies have implied that, among the biomarkers associated with emphysema, matrix metalloproteinase 9 (MMP-9) is of particular importance. Increased plasma MMP-9 levels are proposed to predict the decline of lung function as well as greater COPD exacerbations in A1AT deficiency-associated emphysema. The aim of the present study was to investigate the effect of A1AT therapy (Prolastin) on plasma MMP-9 and myeloperoxidase (MPO) levels. In total 34 PiZZ emphysema patients were recruited: 12 patients without and 22 with weekly intravenous (60 mg/kg body weight) A1AT therapy. The quantitative analysis of A1AT, MMP-9 and MPO was performed in serum and in supernatants of blood neutrophils isolated from patients before and after therapy. Patients with Prolastin therapy showed significantly lower serum MMP-9 and MPO levels than those without therapy. However, parallel analysis revealed that a rapid infusion of Prolastin is accompanied by a transient elevation of plasma MMP-9 and MPO levels. Experiments with freshly isolated blood neutrophils confirmed that therapy with Prolastin causes transient MMP-9 and MPO release. Prolastin induced the rapid release of MMP-9 and MPO when added directly to neutrophil cultures and this reaction was associated with the presence of IgA in A1AT preparation. Our data support the conclusion that changes in plasma levels of MMP-9 and MPO mirror the effect of Prolastin on blood neutrophils.
Many Faces of the Correlation Coefficient (1997)

Some selected interpretations of Pearson's correlation coefficient are considered. Correlation may be interpreted as a measure of closeness to identity of the standardized variables. This interpretation has a psychological appeal in showing that perfect covariation means identity up to positive linearity. It is well known that |r| is the geometric mean of the two slopes of the regression lines. In the 2 × 2 case, each slope reduces to the difference between two conditional probabilities so that |r| equals the geometric mean of these two differences. For bivariate distributions with equal marginals, that satisfy some additional conditions, a nonnegative r conveys the probability that the paired values of the two variables are identical by descent. This interpretation is inspired by the rationale of the genetic coefficient of inbreeding.
Diagnostic accuracy of cytology and biopsy in primary bronchial carcinoma. (1979)

The accuracy of diagnosis of cell type obtained from sputum cytology, bronchial aspirate, bronchial biopsy, or percutaneous lung biopsy in 161 cases of confirmed primary lung cancer has been examined and the pretreatment histological diagnosis has been compared with the final diagnosis made after surgical resection or necropsy. The yield of positive diagnoses of malignancy obtained by each method of investigation in each cell type showed that cytological examination of sputum was the most accurate method, but a high degree of accuracy was also obtained by bronchoscopic aspiration and bronchial biopsy. Percutaneous lung biopsy was the most effective, but the least accurate, means of obtaining carcinoma cells. The level of diagnostic accuracy was highest in patients with squamous cell carcinoma. Accurate pretreatment diagnosis of patients with adenocarcinoma was particularly difficult, and only 20% of these cases were correctly diagnosed by investigation. Of seven patients with adenocarcinoma and a positive diagnosis of malignancy made on percutaneous lung biopsy, none was correctly diagnosed. The causes of error in diagnosis of cell type of primary lung cancer are discussed.
Ni-Ti Alloys for Aerospace Bearing Applications (2017)

Nickel-rich Ni-Ti alloys are emerging candidate materials for aerospace bearing applications. These alloys exhibit a unique combination of physical, chemical, and tribological properties that are highly relevant to challenging aerospace bearings and other mechanical components. Despite being made solely from metals, Ni-Ti alloys are classified as intermetallics with properties akin to both metals and ceramics. For instance, like metals, they are electrically conductive but they tend to be brittle like ceramics. When properly processed, they have high hardness, low elastic modulus and an extensive elastic deformation range that imparts extraordinarily high resilience and resistance to denting. New alloy compositions enable simpler thermal processing and machining and intensive microstructural analyses have helped elucidate the materials science mechanisms governing hardness. In this paper, the application of state-of-art in NiTi alloys for aerospace bearings and mechanical components is explored. In addition to reviewing future trends and remaining challenges, the unique approaches and methods of tailoring bearing design to accommodate NiTis unique properties is discussed.
