Motion Correction in Magnetic Resonance Imaging Using the Signal of Free-Induction-Decay (2016)

Magnetic resonance imaging (MRI) is highly susceptible to subject's motion and can significantly degrade image quality. In brain MRI exams, involuntary head movements can affect the sampled k-space data. Such unintended alterations may result in visible image artifacts such as blurring, ghosting and others, and therefore potentially disqualify the image from diagnostic purposes. Methods to characterize motion in order to mitigate its impact on image quality exist and range from MR sequence based techniques to scanner independent tracking systems. Although, many motion detection and correction strategies have been proposed in the past, a universal solution to the problem does not exist yet. The work of this thesis was focused on the exploitation of the motion information from a multi-channel Free Induction Decay Navigator (FID) to develop and to optimize motion detection and correction methods in structural brain MRI. After a short introduction to the motion problem in MRI the fundamental methodology behind FID based motion detection is presented and used in this thesis. Considerable work has already been done in the field of motion correction for MRI that is summarized by reviewing the most recent literature, which allowed to reveal some pitfalls in the present approaches and to demonstrate the motivation behind an FID-based method for motion correction in MRI. The first study was conducted to demonstrate that substantial motion information is contained in the multi-channel FID signal, whereby the FID signal is correlated with motion parameters that were obtained from a highly accurate optical tracking system. This work was able to confirm the theoretical foundations from the Biot-Savart law, however, also revealed that a pure FID-based method is not sufficient to exactly calculate the underlying motion trajectory. It is speculated that scanner and subject related information might lead to a closed form solution, yet it was not possible to derive one due to a high dimensionality of the motion problem. Therefore, two alternative approaches were developed to utilize the FID signal for motion detection and correction in MRI. First, a prospective motion correction strategy for an MP-RAGE sequence is demonstrated, whereby the FID signal is used to trigger a prospective motion correction mechanism. The second alternative approach describes how the FID signal can be used to evaluate the quality of an already acquired image and how the FID signal can be used as an optimizer for an autofocusing based retrospective motion correction technique.
Survival of Colorectal Cancer Patients Hospitalized in The Veterans Affairs Health Care System (2003)

Recent non-VA studies have shown stable survival for colorectal cancer patients over time, coupled with significantly decreased survival for blacks compared with whites. In contrast, in the VA system, survival has improved for both white and black patients; in addition, the racial discrepancy in survival is markedly attenuated. These results suggest that the benefits of prevention and treatment advances may be more readily achieved in the VA's equal access, integrated health care system.

Identification of adenosine triphosphate in human plasma and the concentration in the venous effluent of forearm muscles before, during and after sustained contractions (1969)

1. When diluted human plasma is perfused through a frog heart, a marked augmentation of the heartbeat is produced which is very similar in action to that of low concentrations of adenosine triphosphate (ATP) on the heart.2. It was established that the substance in the plasma responsible for the heart stimulation was ATP. The following tests were used: (a) the diluted plasma emitted light from firefly lantern extract characteristic of the light signal produced by a solution of ATP; (b) the stimulatory effect on the frog heart and luminescent effect upon the firefly extract were abolished by incubation of the plasma solution with the enzyme apyrase, which converts ATP to adenosine monophosphate (AMP); AMP does not stimulate the heart or cause light to be emitted from firefly extract; (c) the stimulatory substance in the plasma was eluted through a column of Sephadex G-25 in the same pattern as ATP; and (d) simultaneous assay of plasma solutions on frog heart and firefly extract produced the same quantitative result as that produced by a solution of ATP.3. The amount of ATP in plasma from the venous blood of resting subjects ranged from 0.19 to 0.95 mug/ml. (mean 0.63 mug/ml., S.D. +/- 0.25); up to half of the ATP detected could be attributed to blood platelet damage. Simultaneous arterial and venous samples of blood from four subjects at rest had mean concentrations of 0.19 mug/ml. (0.07-0.26 mug/ml.) and 0.70 mug/ml. (0.57-0.84 mug/ml.) respectively.4. The concentration of ATP in the venous effluent from exercising forearm muscles was measured. The venous concentration consistently increased over the resting values in response to exercise while in one subject little change occurred in the arterial blood concentration during the exercise. It was concluded that the ATP was added to the blood in its passage through the muscle bed.5. The origin of the ATP, including erythrocytes, blood platelets and active skeletal muscle, is discussed.
Prevalence of <i>Salmonella</i> Typhimurium infection in Norwegian hedgehog populations associated with two human disease outbreaks (2002)

Faecal carriage of salmonella was investigated in 320 hedgehogs from Moss municipality in south-eastern Norway, Askøy, Bergen and Os municipalities in central-western Norway, and five municipalities in south-western and central Norway. The sampling in Moss was carried out 1 year after a human outbreak of salmonellosis, whereas the sampling in Askøy, Bergen and Os was carried out during a human outbreak. Both outbreaks were caused by Salmonella Typhimurium 4,5,12:i:1,2. No salmonella were detected in the hedgehogs from south-western (0/115) and central (0/24) Norway. Thirty-nine percent (39/99) of the animals sampled on Jeløy, and 41% (34/82) of those from Askøy, Bergen and Os, carried S. Typhimurium 4,5,12:i:1,2. The PFGE profile of isolates from hedgehogs and human beings were identical within each of the two outbreak areas. A significantly higher carrier rate of S. Typhimurium occurred among hedgehogs sampled at feeding places, compared to those caught elsewhere. The salmonella-infected hedgehog populations most likely constituted the primary source of infection during both of the human disease outbreaks, and the Norwegian hedgehog is suggested as a reservoir host of S. Typhimurium 4,5,12:i:1,2.
Preparation of Some Aromatic <i>iso</i> thiocyanates (1960)

Training <i>v</i>-Support Vector Regression: Theory and Algorithms (2002)

We discuss the relation between epsilon-support vector regression (epsilon-SVR) and nu-support vector regression (nu-SVR). In particular, we focus on properties that are different from those of C-support vector classification (C-SVC) and nu-support vector classification (nu-SVC). We then discuss some issues that do not occur in the case of classification: the possible range of epsilon and the scaling of target values. A practical decomposition method for nu-SVR is implemented, and computational experiments are conducted. We show some interesting numerical observations specific to regression.
Revisiting the JDL Data Fusion Model II (2004)

The adoption of pest-resistant transgenic plants to reduce yield loss and pesticide utilization has been successful in the past three decades. Recently, transgenic plant expressing double-stranded RNA (dsRNA) targeting pest genes emerges as a promising strategy for improving pest resistance in crops. The steroid hormone, 20-hydroxyecdysone (20E), predominately controls insect molting via its nuclear receptor complex, EcR-USP. Here we report that pest resistance is improved in transgenic tobacco plants expressing dsRNA of EcR from the cotton bollworm, Helicoverpa armigera, a serious lepidopteran pest for a variety of crops. When H. armigera larvae were fed with the whole transgenic tobacco plants expressing EcR dsRNA, resistance to H. armigera was significantly improved in transgenic plants. Meanwhile, when H. armigera larvae were fed with leaves of transgenic tobacco plants expressing EcR dsRNA, its EcR mRNA level was dramatically decreased causing molting defects and larval lethality. In addition, the transgenic tobacco plants expressing H. armigera EcR dsRNA were also resistant to another lepidopteran pest, the beet armyworm, Spodoptera exigua, due to the high similarity in the nucleotide sequences of their EcR genes. This study provides additional evidence that transgenic plant expressing dsRNA targeting insect-associated genes is able to improve pest resistance.

Nuclear reactor control (1955)

Attention is called to the fundamentals of the nuclear reactor art as it is practiced. Special attention is given to certain problems which confront electrical engineers who are responsible for the control of nuclear reactors.
Linearised bipolar transconductor (1992)

A novel bipolar transconductor is presented which offers lowered harmonic distortion levels without having to reduce the transconductance. The proposed arrangement combines a standard long-tailed pair with matched devices having their common emitter connection driven by the common-mode input signal. Experimental evidence suggests that a monolithic implementation could achieve distortion levels of 0.1% or better with differential inputs up to 2VT.
Isolation improvement between loop antennas with absorber cells (2011)

This paper presents a new method to improve isolation between two loop antennas with absorber cells exhibiting negative permittivity and permeability at the aimed frequency of 2.45 GHz. The metamaterial (MTM) unit cell was constructed by two open complimentary split ring resonator (OCSRR) and a split ring resonator (SRR) arrangement. The proposed antenna structures were composed of two loop antennas occupying a space with the dimensions of 51 mm × 24 mm × 2 mm and three absorber cells. The size of each absorber unit cell was 7.4 mm × 7 mm × 2mm. The isolation of more than -20 dB was achieved with three absorber cells loaded between two loop antennas; inter-antenna spacing (center to center) was 0.23 λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> at 2.45 GHz. The results show that port isolation can be improved with absorber cells between two antennas.
Shunt Revision by Coagulation with Retention of the Ventricular Catheter (1998)

Intraluminal coagulation of a ventricular catheter followed by its removal and replacement is a technique used for proximal shunt revision. The authors describe experience leaving the original catheter in place when flow of CSF is established by the coagulation. Advantages of this modification include maintenance of ventricular access when the ventricles are small and the possibility of reducing the incidence of subsequent shunt obstruction by mitigating intraventricular hemorrhage caused by catheter removal.
How I Manage Plantar Fasciitis (1983)

In brief: Heel pain is the most common symptom of plantar fasciitis. It is most noticeable while taking the first few steps in the morning and usually occurs with each step while running, although some people have pain only after running. Treatment options include stretching, ice massage, taping, high-voltage galvanic stimulation and phonophoresis, anti-inflammatory medication, and orthoses. If symptoms are resistant to conservative treatment, surgery may be required.
[Correlation between structure and radioprotective activity (RPA) in thiazole derivatives]. (1994)

The method of potential functions was used to predict adequately the radioprotective efficacy of thiazole derivative series, the geometrical indexes (1n A2 and A6) and anti-ion mass being applied as descriptors for organic and inorganic molecule parts respectively.
Thermal expulsion of helium from a quenching cable-in-conduit conductor (1981)

Three problems are solved in this paper, all by similarity solutions. The first is thermal expulsion from an entire hydraulic circuit initially unpressurized but uniformly heated by the Joule power of the normal conductor. The second problem is expulsion from an unheated but initially pressurized conductor. In both of these problems, the ends of the conductor are imagined to intrude into constant-pressure chambers. The second problem has less practical importance in applied superconductivity than the first, but it teaches us some useful things that aid in the solution of the third problem. In the third problem, the ends of the heated part of the conductor intrude into unheated parts of identical construction rather than constant-pressure chambers. This problem sheds some light on normal-zone propagation in cable-in-conduit conductors.
Shrinking lungs, diaphragmatic dysfunction, and systemic lupus erythematosus. (1985)

One of the more unusual respiratory manifestations of systemic lupus erythematosus is "shrinking lungs." We report a patient with this syndrome and provide evidence for this being due to diaphragm dysfunction. Significant improvement occurred after albuterol therapy, providing new possibilities in the treatment of this syndrome. This is the first report in humans supporting animal work demonstrating that beta-agonists can improve diaphragmatic performance.
Anthropometric Analysis of Palpebral Fissure Dimensions and its Position in South Indian Ethnic Adults (2013)

Statistically significant differences were found between South Indian ethnic males and female in certain key parameters. The present study suggests that ethnicity and gender should be considered in orbital surgery. To individualize the treatment planning and diagnosis, it is important for the surgeons to have knowledge of these local norms.
Well Abandonment: Abrasive Jetting to Access a Poorly Cemented Annulus and Placing a Sealant (2012)

Abstract This paper describes a method for well abandonment using Coiled Tubing. It provides a rigless well abandonment technique for wells that suffer from sustained casing pressure (SCP) in one or more annuli. The method uses abrasive jets for cutting holes into casing(s). The holes cover the full circumference of the casing, i.e. 360 degrees. This is performed at two depth levels, spaced 5 meters apart (adjustable). The assembly can be run on coiled tubing and rotated using an indexing tool. After placing a retainer plug between the two depth levels, a sealant material can be squeezed behind the casing to stop the Sustained Casing Pressure or gas percolation in the annulus. A full-scale yard trial of the system is presented in this paper. The tool design, testing procedure, and results are discussed. The system is currently nearing the end of the testing phase.
Evidence of anti-oxidant role of sucralfate in gastric mucosal protection. (1990)

Six percent hydrogen peroxide (H2O2) was used as a generator of the *OH free radical, and as an aggressor of gastric mucosa, in 100 Wistar rats. The mucosal cytoprotector effect of sucralfate, misoprostol, enprostil, cimetidine, ranitidine, famotidine and 10% aluminum sulphate yielded almost complete macroscopic and histological protection to the gastric mucosa. Misoprostol or enprostil gave partial protection whereas the H2 blockers aggravated the gastric necrotic lesions produced by the H2O2. We conclude that sucralfate is a true anti-oxidant that protects the gastric mucosa through its aluminum and sulphydril components, the increment of gastric mucins and endogenous PGs.
Special considerations in interpreting liver function tests. (1999)

A number of pitfalls can be encountered in the interpretation of common blood liver function tests. These tests can be normal in patients with chronic hepatitis or cirrhosis. The normal range for aminotransferase levels is slightly higher in males, nonwhites and obese persons. Severe alcoholic hepatitis is sometimes confused with cholecystitis or cholangitis. Conversely, patients who present soon after passing common bile duct stones can be misdiagnosed with acute hepatitis because aminotransferase levels often rise immediately, but alkaline phosphatase and gamma-glutamyltransferase levels do not become elevated for several days. Asymptomatic patients with isolated, mild elevation of either the unconjugated bilirubin or the gamma-glutamyltransferase value usually do not have liver disease and generally do not require extensive evaluation. Overall hepatic function can be assessed by applying the values for albumin, bilirubin and prothrombin time in the modified Child-Turcotte grading system.

In vivo bioluminescent determination of apparent K<sub>m</sub>‘s for aldehyde in recombinant bacteria expressing luxA/B (1989)

Recombinant bacteria which express only the luxA and luxB genes have a bioluminescent phenotype providing exogenous long chain aldehyde is supplied in the medium or as a vapour. As an integral part of the biochemistry of photon emission, sub‐saturating concentrations of aldehyde are reflected as sub‐maximal cellular bio‐luminescence. This may be correlated in a kinetic analysis to provide apparent Km values. An analysis of such data across a spectrum of Gram‐positive and Gramnegative bacteria was used to provide a limit for the sensitivity of aldehyde detection. The future development of a rapid bioluminescence‐based rancidity test in foods and oils is discussed.
Low-cost 320 x 240 uncooled IRFPA using conventional silicon IC process (1999)

A 320 x 240 uncooled infrared focal plane array (IRFPA) with series PN junction diodes fabricated on a Silicon-On-Insulator (SOI) wafer has been developed. Resistive bolometers, pyroelectric detectors and thermopile detectors have been reported for large scale uncooled IRFPAs, while the detector developed uses the temperature dependence of forward-biased voltage of the diode . The diode has low 1/f noise because it is fabricated on the monocrystalline SOI film which has few defects. The diode is supported by buried silicon dioxide (BOX) film of the SOI wafer, which becomes a part of a thermal isolated structure by using bulk silicon micromachining technique. The detector contains an absorbing membrane with a high fill factor of 90% to achieve high IR absorption, and the readout circuit of the FPA contains a gate modulation integrator to suppress the noise. Low cost IRFPA can be supplied because the whole structure of the FPA is fabricated on commercial SOI wafers using a conventional silicon IC process.
A nonbacktracking matrix decomposition algorithm for routing on Clos networks (1993)

A number of matrix decomposition schemes have been previously reported for routing on Clos switching networks. These schemes occasionally fail to find the right decomposition, unless backtracking is used. It is shown that a partition may occur during the decomposition process, and that this is the underlying reason these algorithms fail for some decompositions. A parallel algorithm which can recognize when a partition exists and set up the Clos network without backtracking is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A study into the extracted ion number for NASICON structured Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> in sodium-ion batteries (2014)

Excellent C-rate and cycling performance with a high specific capacity of 117.6 mA h g(-1) have been achieved on NASICON-structure Na3V2(PO4)3 sodium-ion batteries. Two different Na sites, namely Na(1) and Na(2), are reported in the open three-dimensional framework, of which the ions at the Na(2) sites should be mainly responsible for the electrochemical properties. It is vitally important and interesting to find that there are two kinds of possible ion occupation of Na ions in Na3V2(PO4)3 and the investigation of ion-extraction number is firstly explored by discussing ion occupations with the help of first-principles calculations. The ion occupation of 0.75 for all Na sites is suitable for the configuration of [Na3V2(PO4)3]2, and the two-step extraction process accompanied by structure reorganization can account for the theoretical capacity of Na3V2(PO4)3.
