Study of shear force as a distance regulation mechanism for scanning near-field optical microscopy (1996)

Results of the investigation into the suitability of the shear-force distance regulation mechanism for scanning near-field optical microscopy (SNOM) are presented. It is shown that there is a range of relative sizes of surface features to tip size that gives rise to malfunctions of the shear-force distance regulation mechanism. If the size of the tip is comparable to the size of any depressions on the sample, the corresponding shear-force image may show contrast reversal. It is also shown that the resolution obtained when imaging a surface with the shear-force scanning microscope may differ for the two perpendicular lateral directions. The resolution along the oscillation axis is usually lower than the one perpendicular to it. This has implications for SNOM images. Therefore, the interpretation of shear force, and hence SNOM images, may become complex when imaging any sample with significant surface roughness.
Superconducting Transition Temperatures of Semiconducting SrTi<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">O</mml:mi></mml:mrow><mml:mrow><mml:mn>3</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math> (1967)

The superconducting transition temperature ${T}_{c}$ of SrTi${\mathrm{O}}_{3}$ has been measured for specimens having electron carrier concentrations ${n}_{c}$ from 6.9\ifmmode\times\else\texttimes\fi{}${10}^{18}$ to 5.5\ifmmode\times\else\texttimes\fi{}${10}^{20}$ ${\mathrm{cm}}^{\ensuremath{-}3}$. The curve exhibits a maximum in ${T}_{c}$ for ${n}_{c}$ near 9\ifmmode\times\else\texttimes\fi{}${10}^{19}$ ${\mathrm{cm}}^{\ensuremath{-}3}$. The transition temperature has also been calculated using one adjustable parameter $\ensuremath{\xi}$, the intervalley deformation potential, in addition to the known normal-state properties of SrTi${\mathrm{O}}_{3}$. A good fit to the experimental curve is obtained.
A Capacitance Bridge Method for Measuring Integrated Corona-Charge Transfer and Power Loss per Cycle (1960)

A more sensitive and accurate circuit has been devised and tested for showing integrated corona charge transfer per cycle in insulation samples. The method can be used as a very accurate and more rapid quality-control measurement of degree of impregnation or residual voids in apparatus insulation. A rather precise measurement of the fraction of gas space to solid in insulation structures can be obtained from this technique. The estimate of internal voids obtained from this technique is believed to be more accurate than that obtained from highvoltage Schering bridge measurements, with which it can be correlated.
Extracranial Nerves in the Posterior Part of the Head (1998)

The results of this study suggest that optimal locations for blockade techniques should be reconsidered. The acquired knowledge concerning greater auricular and minor occipital nerves behind the sternocleidomastoid muscle may aid in preventing intraoperative injuries.
Modification of the Neurotoxic Effect of Influenza Virus in Mice by Xerosin, (1955)

Summary Subcutaneous injections of xerosin in mice previously inoculated intracerebrally with toxic doses of either influenza A or B virus delayed the onset of tonic convulsions induced by twirling the mice. Xerosin did not affect the toxic effect of influenza virus inoculated intravenously. Intracerebral injection of xerosin before, but not after, inoculation of virus by the same route completely prevented convulsions and mortality.
Detection of circulating tumor cells in multiple myeloma by a PCR-based method. (1993)

Multiple myeloma (MM) is a B-cell malignancy characterized by clonal expansion of plasma cells producing monoclonal immunoglobulins. It has been regarded as a tumor typically involving only the bone marrow. The existence of circulating tumor cells has been suggested from phenotypic and genotypic studies. However, this issue is still controversial due to the limitations of the methods so far used. We describe a novel polymerase chain reaction (PCR) based method using clone-specific immunoglobulin heavy-chain gene sequences as tumor markers. From such sequences patient-specific oligonucleotide primers and probes were generated, and used to detect tumor cells. Seven MM patients were selected for this study, and tumor cells were found in all peripheral blood samples. The demonstration of circulating tumor cells suggests some caution when using peripheral blood for autograft procedures, even though its contamination is lower than bone marrow. In conclusion, we describe a specific and sensitive PCR-based method for detecting minimal disease which is of general applicability to all lymphoid malignancies transcribing rearranged immunoglobulin heavy-chain genes.
Rigorous, multimode equivalent network representation of inductive discontinuities (1990)

The theoretical derivation of the equivalent networks has been carried out by following the rigorous procedure used by M. Guglielmi and A.A. Oliner (1989) for the case of a metal strip grating at an air-dielectric interface. Following this procedure, network representations involving multimode coupling matrices are found in terms of the solution of a singular integral equation. The solution to this equation is shown to be known so that rigorous, multimode equivalent network representations for zero-thickness inductive windows and inductive obstacles in a rectangular waveguide can be derived. The network representations developed are valid for arbitrary aperture/obstacle dimensions and offset, and can accommodate a different medium on each side of the discontinuity. The analytic expressions obtained involve double integrations which are easily evaluated numerically. Numerical results are also presented indicating that the network representations developed are rapidly convergent so that they can be easily used to carry out computations involving an arbitrary number of propagating higher-order modes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<title>Distributed video server using a new striping technique</title> (1998)

In this paper, we propose a new striping control technique for a distributed video server that makes it possible to provide a large number of video streams and enables system scalability. This is based on three key techniques: (1) multiple access using time-slot sequences that each server module controls independently to reduce the communication overhead between the modules and to shorten the response time, (2) load balancing using replicated segments to provide video streams without interruption, and (3) logical server modules and disks which makes it possible to manage carious types of server modules and disks uniformly. Simulations confirmed the superiority of our technique compared to other proposed techniques. We also built an experimental systems. This experimental systems also confirmed the effectiveness of our technique.
Identification of dyeing mordants and related substances on textile fibers: a preliminary study using energy dispersive X-ray spectrometry (1985)

Samples of modern wool, silk and cotton woven fabrics were mordanted with five common dyeing mordants: potassium aluminum sulfate, cupric sulfate, ferrous sulfate, stannous chloride and potassium dichromate. Samples were observed by scanning electron microscopy (SEM) and metallic elements detected by energy dispersive X-ray spectrometry (EDS). The results and limitations of the detection process are discussed and compared to other analytical procedures. The application of this procedure to historical textiles for analysis of metallic mordants and certain dyes is discussed.
DIVER: A Distributed Virtual Environment Research platform (1993)

DIVER is the Virtual Environment software architecture library developed at the University of Virginia. It is similar to SGI's Inventor, but was developed specifically as a toolkit for creating Virtual Environments rather than for mouse-based applications. Like Inventor, DIVER was implemented on top of the SGI's GL library and provides a powerful hierarchical graphics database. Unlike Inventor, DIVER is distributed, divorcing the application computations from the rendering computations. DIVER runs the application on a remote CPU and transparently spawns asynchronous rendering processes onto one or more SGIs. DIVER extends the graphics database hierarchy by allowing programmers to perform graphics transformations in any other object's nested coordinate system, and by allowing the programmer to nest the virtual camera (viewpoint) anywhere in the hierarchy. DIVER has been active use for over a year by more than twenty researchers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Flexible Charging Optimization for Electric Vehicles Considering Distribution Grid Constraints (2011)

In this paper, the basic functions of an electric vehicle charging service provider are described with a focus on the associated optimization problems. A novel method of planning the charging of electric drive vehicles including electricity grid constraints, both voltage and power, is shown. The method establishes an individual charging plan for each vehicle and avoids distribution grid congestion while satisfying the requirements of the individual vehicle owners. The concepts proposed in this paper are tested on a simulated electricity grid. It is shown that both power and voltage constraints due to electric vehicle charging can be avoided using the proposed method.
Correlated-emission laser: Nonlinear theory of the quantum-beat laser (1988)

A nonlinear quantum theory of the quantum-beat laser is developed using a ``dressed-atom--dressed-mode'' master-equation approach. The theory is valid under the detuning conditions which led to correlated spontaneous emission in a linear theory. It is shown that the quenching of the quantum noise remains valid in the nonlinear theory and this operation is stable above threshold.
Expression of Class III β-Tubulin Is Predictive of Patient Outcome in Patients with Non–Small Cell Lung Cancer Receiving Vinorelbine-Based Chemotherapy (2005)

These findings suggest that a high level of expression of class III beta-tubulin in tumor cells is associated with resistance to vinorelbine and a poor prognosis in patients with NSCLC receiving vinorelbine-based chemotherapy.
Gonadal Shield (1975)

A secondary gonadal shield for use in the pelvic irradiation of males was designed and built using material and apparatus available with the Cerrobend blocking system. The gonadal dose was reduced to approximately 1.5 to 2.5% of the given dose.
An External Demand Pacemaker Evaluation System (1989)

Clinical engineering departments have the responsibility for calibration and performance assurance for all applicable clinical instrumentation in the most efficient manner possible. The University of Connecticut Health Center has established an external pacemaker testing protocol that improved the quality of patient safety. Fabrication of an external demand pacemaker test device has enabled our Clinical Engineering department to quickly check compliance with specifications recommended by the manufacturer and Emergency Care Research Institute (ECRI). This test device, including the fabrication and necessary documentation, will be explained for the benefit of other Clinical Engineering facilities.
A Classification Analysis using Bayesian Neural Network (2001)

There are several algorithms for classification in modeling relations, patterns, and rules which exist in data. We learn to classify objects on the basis of instances presented to us, not by being given a set of classification rules. The Bayesian learning uses the probability distribution to express our knowledge about unknown parameters and update our knowledge by the law of probability as the evidence gathered from data. Also, the neural network models are designed for predicting an unknown category or quantity on the basis of known attributes by training. In this paper, we compare the misclassification error rates of Bayesian Neural Network method with those of other classification algorithms, CHAID, CART, and QUBST using several data sets.
SOX2 promotes dedifferentiation and imparts stem cell-like features to pancreatic cancer cells (2013)

SOX2 (Sex-determining region Y (SRY)-Box2) has important functions during embryonic development and is involved in cancer stem cell (CSC) maintenance, in which it impairs cell growth and tumorigenicity. However, the function of SOX2 in pancreatic cancer cells is unclear. The objective of this study was to analyze SOX2 expression in human pancreatic tumors and determine the role of SOX2 in pancreatic cancer cells regulating CSC properties. In this report, we show that SOX2 is not expressed in normal pancreatic acinar or ductal cells. However, ectopic expression of SOX2 is observed in 19.3% of human pancreatic tumors. SOX2 knockdown in pancreatic cancer cells results in cell growth inhibition via cell cycle arrest associated with p21(Cip1) and p27(Kip1) induction, whereas SOX2 overexpression promotes S-phase entry and cell proliferation associated with cyclin D3 induction. SOX2 expression is associated with increased levels of the pancreatic CSC markers ALDH1, ESA and CD44. Importantly, we show that SOX2 is enriched in the ESA(+)/CD44(+) CSC population from two different patient samples. Moreover, we show that SOX2 directly binds to the Snail, Slug and Twist promoters, leading to a loss of E-Cadherin and ZO-1 expression. Taken together, our findings show that SOX2 is aberrantly expressed in pancreatic cancer and contributes to cell proliferation and stemness/dedifferentiation through the regulation of a set of genes controlling G1/S transition and epithelial-to-mesenchymal transition (EMT) phenotype, suggesting that targeting SOX2-positive cancer cells could be a promising therapeutic strategy.

Plans for the Bishops Stortford (UK) fibre to the home trials (1990)

Plans for a British trial of novel topologies for fiber to the home are now at an advanced stage. The reasons and objectives for the trial, the technologies to be deployed, and the proposed layout and timing of the trial are outlined. The following objectives were set for the trial: (1) to demonstrate the technical feasibility of using optical fibers in the local loop for small business and single-line telephony customers: (2) to provide experience in practical operational aspects of the optical local network, including installation, moving of customers, reliability, maintenance, and network control; (3) to allow comparison of active and passive architectures with regard to cost, technical performance, and ease of operation and customer response; (4) to provide experience that will allow projection of procurement and operational cost with greater confidence than at present; and (5) to provide the first-hand knowledge that will permit its full participation in the world debate on topologies, technologies, and standards for optical local networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimising drug treatment for elderly people: the prescribing cascade (1997)

Old age has always been with us.The ancient Egyptians and the author of the 12th chapter of Ecclesiastes were familiar with the common disabilities of later life.Survival into what we still regard as old age was not unusual in classical Greece (table).The average length of human life has increased over the centuries as living conditions have improved and childhood mortality has fallen; the maximum lifespan of our species is determined largely by our genes and will be the same as it ever was.Doctors and philosophers of antiquity commented on age associated illness.Hippocrates noted conditions common in later life, and Aristotle offered a theory of aging based on loss of heat.Two thousand years were to pass before anything better was written on the subject.Francis Bacon proposed a scientific programme of epidemiological investigations into the longevity of people living in different places and under different conditions. 1 He also noted that the pursuit of knowledge depended on "the fresh examination of particulars," advice that underlaid the systematic observation of nature that complemented the active experimentation advocated by his contemporary William Harvey.During the 18th and 19th centuries several physicians wrote specifically about the diseases of later life and their treatment.These included Cheyne 2 and Day 3 in Britain and Rush 4 in the United States.Charcot's lectures on the medicine of old age aroused scientific interest in the field and became available in English translation in 1881. 5 The word "geriatrics" was invented by Ignatz L Nascher, a Vienna-born immigrant to the United States in 1909. 6(It is not clear who is to blame for the barbarous miscoining of "gerontology"-the study of old men-for "geratology"-the study of old age.)Nascher's initiative provided a stimulus for social and biological research on aging, 7 but clinical geriatrics did not flourish in the United States.The American Geriatrics Society was founded in 1942, but as a thriving and influential medical specialty geriatric medicine was essentially a product of the British NHS.

Clearance of Insoluble Dust from the Lower Respiratory Tract (1964)

Studies of the clearance of dusts of low solubility from the lower respiratory tracts of dogs utilizing in vivo counting, revealed that for a given aerosolized substance there was a consistent clearance pattern, but among different substances, e.g. ferric oxide, manganic oxide, mercuric oxide, barium sulfate and uranium dioxide, the rate of LRT clearance differs widely during the second phase, i.e. after the first few days. Evidence obtained from excretion data and ultrafiltration studies suggests these differences were determined by the respective in vivo solubilities of the materials studied. Variations in the amount or particle size of a particular aerosol altered the quantitative aspects of both clearance phases but neither appeared to affect the rates of dust clearance in either phase.
Synthesis of 2-Alkoxy 1,4-Naphthoquinone Derivatives as Antiplatelet, Antiinflammatory, and Antiallergic Agents. (2002)

In our continuing search for novel antiplatelet, antiallergic, and antiinflammatory agents, 2-alkoxy derivatives of 1,4-naphthoquinone were prepared. Some of these compounds showed significant antiplatelet, antiallergic, and antiinflammatory activities. Among them, 2-propoxy-1,4-naphthoquinone and 2-butoxy-1,4-naphthoquinone exhibited potent inhibitory effect on neutrophil superoxide anion formation. These two compounds are worthy of further exploration.
