Electron localisation and superconductivity in thin Cu/Pb proximity layers (1984)

The authors have studied the temperature, magnetic and electric field dependence of the electrical resistance of thin Cu/Pb contacts. The results demonstrate the coexistence of superconducting fluctuations and weak localisation effects well above the critical temperature. The magnetoresistance data are explained on the basis of the theories of Hikami et al. (1980) and Larkin (1980) for two-dimensional disordered systems. Values of the inelastic scattering time tau i, the spin-orbit scattering time tau so and the scattering time from magnetic impurities tau s were obtained for this proximity system.
Lymphocyte function in myasthenia gravis. (1979)

Mitogen-induced blastoid transformation of peripheral blood lymphocytes from patients with myasthenia gravis was studied using a microplate culture technique and evaluated with 3H-thymidine incorporation. It was found that both phytohaemagglutinin and pokeweed mitogen responses decreased significantly in patients with myasthenia gravis. In myasthenic crisis, indices of stimulation by phytohaemagglutination became very low. The autologous plasma neither inhibited nor facilitated mitogenic responses of lymphocytes. The decreased mitogen responsiveness of lymphocytes suggests that part of the T lymphocyte function is subnormal in myasthenia.
Prediction of vibration levels and resonant frequencies in static electrical apparatus (2002)

Results of computer simulations obtained by a finite-element package, FLUXMECA, are presented and compared with experimental measurements of vibrations of static inductors. The objective is to reduce the vibrations' level and the acoustic noise of the transformers. Resonant frequencies and the mechanical behavior of the inductors are predicted with a mechanical finite-element model coupled with Maxwell's equations. A homogenization algorithm allows representation of a stratified structure by a homogenized one. Two kinds of inductors have been tested: cylindrical ones without iron cores and classical iron-cored inductors. A study of the electromagnetic forces and the mechanical structures is presented, clarifying the generation of noise and vibrations in static electrical apparatus.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Hydroxyindole- <i>O</i> -Methyl-Transferase Activity: Effect of Sympathetic Nerve Stimulation (1968)

Stimulation of the preganglionic nerve trunk to the superior cervical ganglion causes a reduction in pineal hydroxyindole- O -methyl-transferase levels which is time-dependent. The results provide direct evidence for a role of afferent input in the control of pineal enzymatic activity.
Increases in Dentin-bond Strength If Doubling Application Time of an Acetone-containing One-step Adhesive (2007)

This study investigated the microtensile bond strength (microTBS) of a one-step self-etching adhesive to human dentin and bovine enamel following different bonding treatments. Occlusal portions of human molars and labial surfaces of bovine incisors were ground flat to provide uniform dentin and enamel surfaces, respectively. Futurabond was used following five different protocols: 1) according to the manufacturer's directions, 2) acid etched with 36% phosphoric acid (H3PO4) for 15 seconds, 3) 10% sodium hypochlorite (NaOCl) treated for two minutes after H3PO4-etching, 4) doubling the application time of the adhesive and 5) doubling the number of adhesive coats. Composite build-ups (6 mm in height) were constructed incrementally with Arabesk resin composite. The specimens were stored in 100% humidity for 24 hours at 37 degrees C and sectioned into beams of 1.0 mm2 cross-sectional area. Each beam was tested in tension in an Instron machine at 0.5 mm/minute, and mean microTBS data (MPa) were analyzed by one-way ANOVA and post-hoc multiple comparisons tests (alpha = 0.05). Doubling the application time of Futurabond attained the highest microTBS to dentin; whereas, no differences among all bonding application parameters evaluated could be detected when the adhesive was applied to enamel.
Multi-Channel late reverberation power spectral density estimation based on nuclear norm minimization (2017)

Multi-channel methods for estimating the late reverberation power spectral density (PSD) generally assume that the reverberant PSD matrix can be decomposed as the sum of a rank-1 matrix and a scaled diffuse coherence matrix. To account for modeling or estimation errors in the estimated reverberant PSD matrix, in this paper we propose to decompose this matrix as the sum of a low rank (not necessarily rank-1) matrix and a scaled diffuse coherence matrix. Among all pairs of scalars and matrices that yield feasible decompositions, the late reverberation PSD can then be estimated as the scalar associated with the matrix of minimum rank. Since rank minimization is an intractable non-convex optimization problem, we propose to use a convex relaxation approach and estimate the late reverberation PSD based on nuclear norm minimization (NNM). Experimental results show the advantages of using the proposed NNM-based late reverberation PSD estimator in a multichannel Wiener filter for speech dereverberation, significantly outperforming a state-of-the-art maximum likelihood-based PSD estimator and yielding a similar or better performance than a recently proposed eigenvalue decomposition-based PSD estimator.
Detection of Human Polyomaviruses in Urine from Bone Marrow Transplant Patients: Comparison of Electron Microscopy with PCR (2004)

UC/EM is rapid and highly specific for polyomavirus in urine. Unlike real-time PCR, EM has low sensitivity and cannot quantify the viral load.

QoS-aware Dynamic Fog Service Provisioning (2018)

Recent advances in the areas of Internet of Things (IoT), Big Data, and Machine Learning have contributed to the rise of a growing number of complex applications. These applications will be data-intensive, delay-sensitive, and real-time as smart devices prevail more in our daily life. Ensuring Quality of Service (QoS) for delay-sensitive applications is a must, and fog computing is seen as one of the primary enablers for satisfying such tight QoS requirements, as it puts compute, storage, and networking resources closer to the user. In this paper, we first introduce FogPlan, a framework for QoS-aware Dynamic Fog Service Provisioning (QDFSP). QDFSP concerns the dynamic deployment of application services on fog nodes, or the release of application services that have previously been deployed on fog nodes, in order to meet low latency and QoS requirements of applications while minimizing cost. FogPlan framework is practical and operates with no assumptions and minimal information about IoT nodes. Next, we present a possible formulation (as an optimization problem) and two efficient greedy algorithms for addressing the QDFSP at one instance of time. Finally, the FogPlan framework is evaluated using a simulation based on real-world traffic traces.

Implementation of a Whole Spacecraft Isolation System for the OSTM/Jason 2 Mission (2008)

The OSTM/Jason 2 mission will be the lightest payload to ever launch on a 2-stage Delta II 7320-10 launch vehicle. The moment-based lateral loads predicted for this launch configuration significantly exceed the qualification history of the inherited spacecraft bus. Additionally, payload sine vibration requirements for this launch configuration exceed the OSTM/Jason 2 spacecraft and equipment sine vibration qualification heritage. It was not possible to appreciably enhance the structural capability of the Jason 2 spacecraft, therefore a feasibility study of various potential approaches for mitigating the launch loads was conducted. A CSA Engineering, Inc., SoftRide whole spacecraft isolation system was chosen for implementation on the OSTM/Jason 2 mission based on probability of meeting the load mitigation criteria and cost and schedule considerations. This paper provides a) an overview of the study that resulted in selection of the SoftRide system, b) the design, analysis, and test process for the SoftRide system, along with some of the design issues and their solutions, and c) a summary of a KSC/JPL independent evaluation of the risks associated with the SoftRide program. The SoftRide solution for OSTM/Jason 2 allowed demonstration of the adequacy of the heritage qualification for the launch configuration.
Production of a tac inhibitory activity by adherent cells of HIV-infected subjects at different clinical stages. (1991)

Studying the mechanisms of the impaired T-cell colony growth from HIV-infected subjects, we have demonstrated that depletion of adherent cells from some patients' peripheral blood mononuclear cells enhanced the plating efficiency of T colony-forming cells. We report here that media conditioned by patients' cells but not normal adherent cells could inhibit the expression of the interleukin-2 receptor alpha (IL-2R alpha) chain but not the IL-2R beta chain in a dose-dependent manner. This inhibitory activity was produced by macrophage-monocyte cells since they displayed the My9+ My7+ OKM1+ phenotype and since adherent cell depletion by complement-mediated cytotoxicity with the My9 monoclonal antibody completely abrogated production of the inhibitory activity. A similar inhibitory activity, which could not be recognized by anti-p24 or anti-gp 120 monoclonal antibody or purified human anti-HIV immun]gobulin G in Western blot assays, could also be detected in culture supernatants of in vitro HIV-infected normal adherent and U937 leukemic cells. Production of IL-2R alpha chain inhibitory activity was associated with a decreased mitogen-induced expression of IL-2R alpha chain on patients' PBMC in 8 of 10 studied cases. Its production could be detected in 82, 58, and 91% of media conditioned by adherent cells from stage II, III, and IV patients, respectively. The amount of IL-2R alpha chain inhibitor released by patients' adherent cells increased during the deterioration of the patients' clinical status, and zidovudine treatment completely abrogated its production in all patients. These findings strongly suggest that production of IL-2R alpha chain inhibitory activity is involved in the pathophysiology of the impaired T-cell responses during HIV infection and could be of clinical relevance during the patients' follow-up.
Can a Self-Expanding Aneurysm Stent Be Clipped? Emergency Proximal Control Options for the Vascular Neurosurgeon (2011)

The Neuroform(3) and Enterprise stents responded favorably to temporary clip application, returning to their original diameter after clip removal and showing no sign of permanent structural modification. The Pipeline flow-diverting stent, however, was irreversibly deformed by clip application. These data indicate that temporary clip application to certain stents is possible. Further in vivo study is required.
Plastic deformations in mechanically strained single-walled carbon nanotubes (2003)

Antiferromagnetic manipulation was used to controllably stretch individual metallic single-walled carbon nanotubes (SWNT's). We have found that SWNT's can sustain elongations as great as 30% without breaking. Scanned gate microscopy and transport measurements were used to probe the effects of the mechanical strain on the SWNT electronic properties, which revealed a strain-induced increase in intra-tube electronic scattering above a threshold strain of \ensuremath{\sim}5--10 %. These findings are consistent with theoretical calculations predicting the onset of plastic deformation and defect formation in carbon nanotubes.
Cultured endothelial cells increase their capacity to synthesize prostacyclin following the formation of a contact inhibited cell monolayer (1983)

The synthesis of the prostaglandins (PG), prostacyclin (PGI2), PGE2, and thromboxane A2 (TXA2), has been investigated in actively growing and contact-inhibited bovine aortic endothelial cell cultures. Cells were stimulated to synthesize prostaglandins by exposure to exogenous arachidonic acid or to the endoperoxide PGH2 and by the liberation of endogenous arachidonic acid from cellular lipids with melittin or ionophore A23187. Increased capacity of the cells to synthesize PGI2 and PGE2 was observed as a function of time in culture, regardless of the type of stimulation. TXA2 production increased with time only upon stimulation of the cells with ionophore A23187. This increased PG synthetic capacity was independent of cell density since it was mainly observed in confluent, nondividing endothelial cell cultures. The fact that increased PGI2 production in confluent cells was also observed with PGH2, a direct stimulator of PGI2 synthetase, implies that this process is independent of the arachidonate concentration within the cells or in the culture medium. This increased capacity is likely to reflect an increased activity of the PG synthetase system associated with the formation of a contact inhibited endothelial cell monolayer. A similar time-dependent increase in the PGI2 production capacity was also observed during growth of cultured bovine corneal endothelial cells.
Semiconductor nanocrystals: from scaling laws to biological applications (2000)

Summary form only given, as follows. In recent years there have been significant advances in the preparation of semiconductor quantum dots by colloidal chemistry routes. CdSe and InAs are examples of materials which can be made as nanocrystals of high quality. These nanocrystals provide an excellent proving ground for examining size dependent scaling laws, and a few examples are described briefly. We have also found that these nanocrystals can play a useful role as luminescent probes for tagging biological molecules. Finally, efforts to use DNA to create complex spatial arrangements of nanocrystals are described.
Rheumatic diseases in an MRL strain of mice with a deficit in the functional Fas ligand (1997)

Rheumatic disease was generated by the gld gene in mice with an MRL background, as it is by the lpr gene, which is a Fas deletion mutant, associated with autoimmune traits. Rheumatic disease in this MRL strain was initiated by an incapacity for Fas/Fas-L-induced apoptosis, resulting in the development of autoimmunity and allowing for a persistent immune response in the affected lesions.
Coil to double helix transition for a polysaccharide (1969)

ι-Carrageenan segments can achieve an ordered conformation in a process which resembles the polypeptide and nucleic acid transitions already known, thereby showing for the first time that intramolecular cohesion between sugar residues can be sufficient to outweigh solvation and polymer-conformational entropy in aqueous solution.
Uncommon allele in APO AI-CIII-AIV gene cluster in a family with congenital generalized lipodystrophy (1997)

Congenital generalized lipodystrophy is a rare inherited disease. One of its features is a disturbance in lipid metabolism characterized by hypercholesterolemia and hypertriglyceridemia. A brother and a sister with congenital generalized lipodystrophy, an 8-year old male and a 12-year old female were studied. The mother and a 6-year old brother were healthy. The genetic analysis of Sstl RFLP of the apo AI-CIII-AIV gene cluster showed the presence of the rare Sstl allele (S2) in the patients but not in the healthy mother and brother. As this uncommon allele has been reported to be related to high plasma triglyceride levels, this association could be relevant in explaining in part the hypertriglyceridemia observed in these patients.
Testing the Psychogenic Vomiting Diagnosis (1991)

We treated four patients with chronic vomiting during childhood in whom a tentative diagnosis of psychogenic vomiting was made after an extensive evaluation. In each case, the diagnosis was reconsidered during the course of treatment, as observations about the patients and their response to interventions accumulated. In three instances, these observations did not fit those expected if the diagnosis of psychogenic vomiting was correct. This led to a reexamination of the organic evaluation and the discovery of an undiagnosed organic contribution to the vomiting. In the fourth patient, gastric emptying studies confirmed that there was a strong psychological contribution to the vomiting, and helped to more carefully define this contribution. Family and individual psychotherapy and treatment were aided by the greater clarity in diagnosis.
A prospective cost–benefit analysis for nylon 4N6FLOQSwabs®: example of the process and potential benefits (2022)

Laboratories and their criminal justice systems are confronted with challenges for implementing new technologies, practices, and policies even when there appears to be demonstrative benefits to operational performance. Impacting decisions are the often higher costs associated with, for example, new technologies, limited current budgets, and making hard decisions on what to sacrifice to take on the seemingly better approach. A prospective cost-benefit analysis (CBA) could help an agency better formulate its strategies and plans and more importantly delineate how a relatively small increase to take on, for example, a new technology can have large impact on the system (e.g., the agency, other agencies, victims and families, and taxpayers). To demonstrate the process and potential value a CBA was performed on the use of an alternate and more expensive swab with reported better DNA yield and being certified human DNA free (i.e., nylon 4N6FLOQSwabs®), versus the traditional less costly swab (i.e., cotton swab). Assumptions are described, potential underestimates and overestimates noted, different values applied (for low and modest to high), and potential benefits (monetary and qualitative) presented. The overall outcome is that the cost of using the more expensive technology pales compared with the potential tangible and intangible benefits. This approach could be a guide for laboratories (and associated criminal justice systems) worldwide to support increased funding, although the costs and benefits may vary locally and for different technologies, practices, and policies. With well-developed CBAs, goals of providing the best services to support the criminal justice system and society can be attained.

Minimum Bit Error Rate Multiuser Detection in Multiple Antenna Aided OFDM (2003)

In this contribution, we propose a Minimum Bit Error Rate (MBER) multiuser detector for Space Division Multiple Access (SDMA) aided Orthogonal Frequency Division Multiplexing (OFDM) systems. It is shown that the MBER detector outperforms the Minimum Mean Squared Error (MMSE) detector, since the MBER detector directly minimizes the BER, while MMSE detector minimize the mean-squared error (MSE), which does not guarantee achieving the minimum BER. When supporting two users, the proposed MBER scheme substantially outperforms the classic MMSE arrangement in the investigated propagation scenario.

A portable monitor for measuring GI motility (2002)

Gastrointestinal (GI) motility is an important indicator of motor activity of the GI tract. Present techniques for measuring motility have disadvantages ranging from patient discomfort to high cost. The authors have built an inexpensive, minimally invasive monitor that can measure frequency of GI motility. They have measured motility from the stomach, the small intestine and the large intestine using this monitor.
509 Research on Ultra-Smooth Surface of Drawn Bar and Wire (2000)

The inner surface roughness of tubes was improved by giving high contact pressure and large plastic strain. A new protrusive die on bearing portion is applied for the ultra-smooth outer surface of drawn bar and wire. This new die gives high pressure with large plastis strain ,and improves surface roughness in comparison with the normal die.
