Recent advances in medical applications of MEMS (2002)

Silicon microfabrication methods have long been used to develop devices and instrumentation for medical applications. Early work at Stanford University during the seventies led to the development of silicon based microelectrode arrays for neural recording and stimulation. Efforts in the eighties led to the development of small size and low cost pressure sensors for measuring blood pressure. Sensors manufactured by various companies, namely Lucas NovaSensor and Motorola, form the core of many disposable blood pressure monitoring kits ubiquitous to all hospital emergency rooms. Recent developments in MicroElectroMechanical Systems (MEMS) have led to further advances with applications in biochemistry and medical diagnostics. Examples include demonstrations of polymerase chain reaction (PCR-the process by which DNA is amplified) on a silicon die and novel DNA detection techniques. Techniques borrowed from the integrated circuit industry have allowed the development and production of MEM devices and transducers in ever smaller size, and consequently larger volumes and lower costs. Such micromachined devices found immediate acceptance among the manufacturers of biomedical instrumentation. For example, disposable blood pressure. Silicon sensors successfully replaced older, strain gauge based transducers. The same microfabrication techniques also allowed the development of novel devices and microinstruments that otherwise would not have been possible, especially in the area of DNA sequencing and analysis. This paper reviews some recent advances in the biomedical and biochemical applications of MEMS technology.
LTR design of discrete-time proportional-integral observers (1996)

Applies the proportional-integral (PI) observer in connection with loop-transfer recovery (LTR) design for discrete-time systems. Both the prediction and the filtering versions of the PI observer are considered. We show that a PI observer makes it possible to obtain time recovery, i.e., exact recovery for t/spl rarr//spl infin/, under mild conditions. Two systematic LTR design methods, one based on an extension of the linear quadratic Gaussian loop-transfer recovery (LQG/LTR) and the other based on linear matrix inequality (LMI), are derived for the discrete-time PI observer case, Explicit expressions for the recovery error when exact recovery is not achievable for all frequencies are also given.
Human Cytomegalovirus IE2 86 and IE2 40 Proteins Differentially Regulate UL84 Protein Expression Posttranscriptionally in the Absence of Other Viral Gene Products (2010)

It has previously been demonstrated that, during human cytomegalovirus infection, the viral IE2 86 and IE2 40 proteins are both important for the expression of an early-late viral protein, UL84. Here, we show that expression of the UL84 protein is enhanced upon cotransfection with either IE2 86 or IE2 40, although IE2 40 appears to play a more important role. The UL84 protein levels are tightly linked to the amount of IE2 40 present, but this does not appear to be true for IE2 86. RNA remains constant for all corresponding proteins, indicating posttranscriptional regulation of UL84. The first 105 amino acids of UL84 are necessary and sufficient for this phenotype, and this region is also required for an interaction with IE2 86 and IE2 40. Treatment with proteasome inhibitors shows that UL84 exhibits some proteasome-dependent degradation, and UL84 is not protected against this degradation when coexpressed with IE2 86 or IE2 40. UL84 also exhibits an inhibitory effect on IE2 86 and IE2 40 protein levels in these cotransfection assays. Further, we show that the amino acid sequence of UL84 is important for the enhancement governed by IE2 40. These results indicate that IE2 86, IE2 40, and UL84 serve to regulate protein expression in a posttranscriptional fashion and that this regulation is independent of other viral proteins.
Pulsed eddy-current response to a conducting half-space (1997)

Eddy-current nondestructive evaluation commonly carried out using single frequency time harmonic excitations, but a pulsed excitation offers a simple and effective alternative. The pulse signals have been calculated for a probe coil whose current rises and falls exponentially, approximating a square wave when the exponential time constant is small. Predictions of the induced electromotive force (EMF) across a coil above a half-space conductor and of the magnetic field on the coil axis have been compared with experiments. The comparison shows excellent agreement between theory and experiment.

MULTISCALE MODELING WITH CARBON NANOTUBES: APPLICATIONS IN ELECTRONICS, SENSORS, DISPLAYS, AND STRUCTURAL NANOCOMPOSITES (2006)

Technologically important nanomaterials come in all shapes and sizes. They can range from small molecules to complex composites and mixtures. Depending upon the spatial dimensions of the system and properties under investigation, computer modeling of such materials can range from first-principles Quantum Mechanics, to Forcefield-based Molecular Mechanics, to Mesoscale simulation methods, to Finite-Element computation of properties. We illustrate all of the above modeling techniques through a number of recent applications with carbon nanotubes (CNTs): (1) effect of adsorbates on CNT-based field-emission displays [1]; (2) CNT-straincontrolled nano electromechanical sensor (NEMS) devices [[2], [3]]; (3) the sensitivity of topological defects on CNT action as chemical sensors [4]; (4) assessing the quality of metal-CNT contacts [5]; and (5) mesoscale morphology of polymer-CNT composites [6, 7] and finite-element computation of electrical and thermal transport [8].
Mode of regulation of natural killer cell activity by interferon (1980)

Whereas xenogeneic tumors such as baby hamster kidney or HeLa cells grow in nude mice, the same cells persistently infected with a variety of viruses are rejected. Spleen cells from normal nude mice were found to be induced to produce interferon and to exert natural killer (NK) activity on virus persistently infected (PI) tumor cells, and not on uninfected parental cells in vitro. The phenotype of the interferon-producing cells and the NK effector cells was found to be the same namely, Qa 5(+), Ly 5(+), ganglio-N- tetraosylceramide, with 35 percent of the NK cells also expressing Thy 1.2. NK activity against virus PI tumor cell lines could be nonspecifically augmented both in vivo and in vitro by prior contact with virus PI tumor cells. It was unambiguously demonstrated with chemically homogeneous mouse interferon that interferon, and not a contaminant, was responsible for the augmentation of NK activity in vitro. Studies on the mode of interferon action in augmenting NK activity revealed that the target cell for interferon action was serologically distinct from the NK effector cell. Anti-Ly 5 + complement (C)-treated spleen cells were depleted of NK activity and the ability to produce interferon, but, upon incubation with interferon for 1-3 h, regained both NK activity and susceptibility to anti-Ly 5 + C. Treatment with anti-Qa 5 + C eliminated NK activity, which could not be restored by the addition of interferon. We conclude that interferon produced by Ly 5(+) cells in response to virus PI tumor cells acts on Ly 5(-) precursor cells and induces their differentiation into functional Ly 5(+) NK effector cells.
2D shape recognition by hidden Markov models (2002)

In computer vision, two-dimensional shape classification is a complex and well-studied topic, often basic for three-dimensional object recognition. Object contours are a widely chosen feature for representing objects, useful in many respects for classification problems. We address the use of hidden Markov models (HMM) for shape analysis, based on chain code representation of object contours. HMM represent a widespread approach to the modeling of sequences, and are largely used for many applications, but unfortunately are poorly considered in the literature concerning shape analysis, and in any case, without reference to noise or occlusion sensitivity. The HMM approach to shape modeling is tested, probing good invariance of this method in terms of noise, occlusions, and object scaling.
Organic geochemistry of the eastern gas shales (1981)

A comprehensive organic geochemical study applied diagnostic geochemical characterization techniques to the shales in an effort to determine if the shales were capable of generating the quantities of gas attributed to them and to see if certain localized areas might be better ones in which to explore for reservoired hydrocarbons. The evaluation included determinations of organic matter richness, organic matter richness, organic matter origin and chemistry, and the thermal history that the rock experienced. This paper briefly discusses the distribution of organic carbon, the nature of the organic matter, and the thermal history of the material deposited in the Appalachian Basin. The nature of the sediments indicates that virtually the entire area was covered with a shallow sea in which conditions were constant for long periods of time. The intermittent growth of the young Appalachians and sight movements of the sea bottom periodically disturbed the delicate ecological and geological situation so that virtually the entire sea, or at least its depths, were depleted in oxygen and become stagnant. These stagnant episodes correspond to the most organic-rich layers in the basin. Alternation in organic-rich and organic-lean shales through upper Devonian time are a record of the sight differences in elevation betweenmore » the oceans and the surrounding land masses. The quality of the organic carbon in the shales, places them among the most exceptional hydrocarbon source rocks in the world and consequently the shales have in place a significant hydrocarbon resource.« less
Genetic Rat Models of Parkinson's Disease (2012)

Parkinson's disease (PD) is a neurodegenerative disease characterized by a specific loss of dopaminergic neurons. Although the vast majority of PD cases are idiopathic in nature, there is a subset that contains genetic links. Of the genes that have been linked to PD, α-synuclein and leucine-rich repeat kinase 2 have been used to develop transgenic rat models of the disease. In this paper we focused on the various transgenic rat models of PD in terms of their ability to mimic key symptoms of PD in a progressive manner. In general, we found that most of these models provided useful tools for the early stages of PD, but the development of new transgenic rats that present significant neuropathologic and motoric deficits in a progressive manner that more accurately mimics PD is needed.
End-Stage Renal Disease and Its Management in Older Adults (1998)

The older patient with renal disease presents the nephrologist with a formidable problem list: treatment of end-stage renal disease (ESRD) in these patients can be viewed as a continuum in the management of several diseases at one time. The older ESRD patient with complex medical problems is a challenge to the health care team, clearly requiring the cooperation of physician, nurse, dialysis technician, social worker, dietician, physical medicine specialist, and a host of other subspecialists. The outcomes, however, are gratifying, in that a satisfactory and enjoyable autumn of life is attainable for many.
Influence of high nitrate salts concentration on dimensional variations of mortars under wet curing (2008)

Cementation is a widely applied technique for the conditioning of low- and intermediate-level radioactive wastes. In particular, the use of cement is an attractive procedure to immobilize evaporator concentrates from aqueous effluents treatment. This study is devoted to bring information on the influence of concentrates mixing solution on the dimensional variations under wet curing of simulated solidified waste forms with high ionic strength. In this study, the salinity of the evaporator concentrates was simulated by adding sodium or potassium nitrates. The length changes were measured, with displacement gauges consisting in linear variable differential transducers. Mortars prepared with solutions of KNO3 or NaNO3 exhibited expansion which increased with the nitrate concentration in the mixing solution, whatever the associated cations. The measured swelling was shown to be governed by a concentration effect which involved diffusion and osmosis: diffusion of the ions of the pore solution into the less concentrated curing solution, and water uptake by the material due to the osmotic pressure gradient between the pore and curing solutions.

Strong Divergence of Reconstruction Procedures for the Paley-Wiener\n Space $\\mathcal{PW}^1_\\pi$ and the Hardy Space $\\mathcal{H}^1$ (2014)

Previous results on certain sampling series have left open if divergence only\noccurs for certain subsequences or, in fact, in the limit. Here we prove that\ndivergence occurs in the limit.\n We consider three canonical reconstruction methods for functions in the\nPaley-Wiener space $\\mathcal{PW}^1_\\pi$. For each of these we prove an instance\nwhen the reconstruction diverges in the limit. This is a much stronger\nstatement than previous results that provide only $\\limsup$ divergence. We also\naddress reconstruction for functions in the Hardy space $\\mathcal{H}^1$ and\nshow that for any subsequence of the natural numbers there exists a function in\n$\\mathcal{H}^1$ for which reconstruction diverges in $\\limsup$. For two of\nthese sampling series we show that when divergence occurs, the sampling series\nhas strong oscillations so that the maximum and the minimum tend to positive\nand negative infinity. Our results are of interest in functional analysis\nbecause they go beyond the type of result that can be obtained using the\nBanach-Steinhaus Theorem. We discuss practical implications of this work; in\nparticular the work shows that methods using specially chosen subsequences of\nreconstructions cannot yield convergence for the Paley-Wiener Space\n$\\mathcal{PW}^1_\\pi$.\n
IMPACT OF PERMETHRIN-TREATED BED NETS ON GROWTH, NUTRITIONAL STATUS, AND BODY COMPOSITION OF PRIMARY SCHOOL CHILDREN IN WESTERN KENYA (2003)

Insecticide-treated bed nets (ITNs) have been demonstrated to reduce morbidity and mortality in children less than five years of age. They have also been shown to improve the nutritional status of these children, but little is known about their impact on the nutritional status of school-age children. We evaluated the impact of ITNs on growth, nutritional status, and body composition of primary schoolchildren less than 13 years of age living in an area of intense perennial malaria transmission in western Kenya. The ITNs did not have a significant impact on linear growth or summary measures of protein-energy malnutrition in this age group. This lack of efficacy most likely relates to the reduced burden of malaria in this age group in a setting of stable transmission pressure. Use of ITNs was associated with a change in body composition with an increase in percent lean body mass (1.2%; P = 0.04). This may be consequent to reduced exposure to malaria with subsequent reduced elaboration of pro-inflammatory cytokines known to promote muscle wasting.
Dose Level and Degree of Ketonemia Produced by Growth Hormone and Adrenocorticotropic Hormone. (1948)

Polarization and wavelength dependence of metal-semiconductor-metal photodetector response (1994)

Photocurrent and transmission studies for 543&lt;λ&lt;1523 nm of metal-semiconductor-metal (MSM) photodetectors on semi-insulating GaAs substrates demonstrate a polarization and wavelength dependence of the coupling of light into the metal electrodes. Devices with electrode periods of 400 and 800 nm were investigated and differences as large as 85% in efficiency between orthogonal polarizations were measured for the 400 nm devices. Modeling of the energy transmission through lamellar periodic structures using a Greens function formalism and incorporating dispersion of the substrate dielectric constant produces semiquantitative agreement with the measurements. Suggestions for future MSM photodetector design are discussed.
Handledning av exjobb - Att uppmuntra självständigt arbete (2013)

I denna rapport presenteras reflektioner over ett examensarbete dar studenten inte uppvisade sjalvstandighet. I situationen som uppstod mellan handledare och exjobbare forlitade sig den senare pa att handledaren skulle sta for det kreativa arbetet. En stor anledning till detta var att exjobbaren kan haft svart att kanna att den faktiskt agde problemformuleringen da det var handledaren som var upphovsman, samt sjalv tidigare arbetat med delar av projektet. En ytterligare anledning var att de tva under arbetet satt i samma rum varfor handledningen blev oplanerad. Exjobbaren kunde fa svar pa sina fragor pa kort varsel utan att sjalv i nagon storre utstrackning tanka igenom problemet. Analys av handelseforloppet med utgangspunkt fran handledningen har utforts. De foreslagna forbattringarna ar att exjobbaren redan vid ett tidigt stadium borde involverats mer i projektets malformulering och upplagg av handledning. Detta skulle kunna leda till en okad relevansniva hos examensarbetaren vilket hojer motivationen i arbetet.

The rare anatomical variant of upper lobe (2021)

Abstract Background Primary disease in thorax associated with an azygos lobe is extremely rare. It is usually identified incidentally on chest X-ray or CT during health checkups with an incidence of up to 0.2%. This is the first study involving 46 of patients found with azygos lobe in surgery of English literature from January 1931 to July 2020. Methods PubMed, EMBASE and the Web of Science databases were searched for full-text literatures met out inclusion criteria. We summarized the clinical data, radiological manifestation, accompanying disease and treatment strategy of all patients. Results 18 eligible studies involving 46 patients were selected for this research. The mean age was 36.5 years old. There were 26 male patients and 20 female patients and the male to female ratio nearly to 1.3:1. There were many different primary diseases with azygos lobe including lung cancer (n = 8), spontaneous pneumothorax (n = 5), esophageal cancer (n = 1), pulmonary sequestration (n = 1), esophageal atresia (n = 2), hyperhidrosis (n = 29). The azygos lobe (azygos lobe in Figs. 1 and 2) is an uncommon anomaly that is found in 1% of anatomic specimens, on about 0.4% of chest radiographs and 1.2% of high resolution CT. The azygos lobe is a developmental anomaly but not a true accessory lobe. Azygos lobe of all patients was diagnosed during the operation. Conclusions Azygos lobe occurs in 0.2% of the population and can make clinical diagnosis difficult. The detection of this anomaly and clarification of its precise anatomical features are important to alert the surgeon to potential problems during surgery.
