A return to passive seismic imaging (2002)

Rekindling the passive seismic imaging effort at Stanford, I have acquired grants with Simon Klemperer of the Stanford Crustal Research Group from both the Petroleum Research Fund and the National Science Foundation to pursue two- and three-dimensional imaging efforts of the subsurface in a passive listening methodology. Utilizing the outstanding SEP hardware and software infrastructure and expertise, I have begun to build the resources necessary to manipulate the massive datasets toward producing an image. Efforts to acquire several existing datasets that seem to fit the requirements of this method are presently underway, while 180 Gbytes of the Santa Clara Valley Seismic Experiment from 1998 arrived in house on the first of March.
[Quantitative magnetic resonance (MR) imaging of bone marrow in leukemia]. (2003)

The SIR of spinal marrow is limited in the characteristic diagnosis of leukemia because of its inability to differential LL from ML. The SIR of spinal marrow can be used to evaluate tumor burden in leukemia.

Safety and Efficacy of Single Incision Laparoscopic Surgery for Total Extraperitoneal Inguinal Hernia Repair (2011)

Almost 20 years after the first laparoscopic inguinal hernia repair was performed, single incision laparoscopic surgery (SILS™) is set to revolutionize minimally invasive surgery. However, the loss of triangulation must be overcome before the technique can be popularized. This study reports the first 100 laparoscopic total extraperitoneal hernia repairs using a single incision. The study cohort comprised 68 patients with a mean age of 44 (range, 18 to 83): 36 unilateral and 32 bilateral hernias. Twelve patients also underwent umbilical hernia repair with the Ventralex patch requiring no additional incisions. A 2.5-cm to 3-cm crescentic incision within the confines of the umbilicus was performed. Standard dissecting instruments and 52-cm/5.5-mm/30(0) laparoscope were used. Operation times were 50 minutes for unilateral and 80 minutes for bilateral. There was one conversion to conventional 3-port laparoscopic repair and none to open surgery. Outpatient surgery was achieved in all (except one). Analgesic requirements were minimal: 8 Dextropropoxyphene tablets (range, 0 to 20). There were no intraoperative or postoperative complications with a high patient satisfaction score. Single-incision laparoscopic hernia repair is safe and efficient simply by modifying dissection techniques (so-called "inline" and "vertical"). Comparable success can be obtained while negating the risks of bowel and vascular injuries from sharp trocars and achieving improved cosmetic results.
[Testing of plastics for orthopedic equipment]. (1978)

The testing of plastics in medicine is regulated by law only for the purpose of implantation. These rules are not including the plastics for skin contact use. In consequence of the increasing offer of the chemical industry, it is necessary to develop specific procedures of testing for these materials, e.g. for the orthopedic engineering.
Technical Note—The Complexity of the Optimal Searcher Path Problem (1986)

In this note we show that the problem of finding an optimal searcher path that maximizes the probability of detecting a stationary target by the end of a fixed time is NP-complete. We also demonstrate that the problem of finding a path that minimizes mean time to detection is NP-hard.
Bronchiolitis as a Possible Cause of Wheezing in Childhood: New Evidence (1984)

A historical cohort study was performed in order to assess the hypothesis that even mild bronchiolitis in infancy in a predictor of wheezing later in childhood. Subjects who had experienced bronchiolitis and a matched control group were compared in terms of reported wheezing 8 years later. A highly significant difference was found between the bronchiolitis group and the control group in terms of current wheezing (P less than .0001, relative risk 3.24). This difference was maintained after adjusting for many potentially confounding variables including family history of allergy and other allergic manifestations in the child. Results suggested that 13.6% of a normal practice population in the age range 6 to 9 years currently wheeze, but that 44.1% of children who experienced bronchiolitis currently wheeze. Based on the incidence of bronchiolitis (4.27/100 children in their first 2 years of life) and the relative odds for wheezing derived from a logistic regression model including variables that measured passive smoking, genetic tendency to wheeze, and bronchiolitis, calculations of attributable risk suggested that wheezing in 9.4% of the population of children who currently wheeze was attributable to bronchiolitis.
Tubulin is the endogenous inhibitor of the glyceraldehyde 3-phosphate dehydrogenase isoform that catalyzes membrane fusion: Implications for the coordinated regulation of glycolysis and membrane fusion (2002)

Previously we demonstrated that specific chromatographically resolvable isoforms of rabbit brain GAPDH catalyze either glycolytic flux or membrane fusion activity (but not both). Moreover, GAPDH membrane fusion activity was latent until it was separated from an endogenous cytosolic inhibitor by anion-exchange chromatography. Herein we demonstrate that the cytosolic inhibitor is nondialyzable, heat-labile, and trypsin-sensitive, thereby identifying it as a cytosolic protein constituent. Chromatographic purification of the rabbit-brain cytosolic protein inhibitor of GAPDH isoform-catalyzed membrane fusion identified a predominant 55-kDa doublet that contained an internal 15-aa peptide identical to a sequence present in alpha-tubulin (residues 65-79). The identity of the 55-kDa doublet as tubulin was substantiated through Western blot analysis and inhibition of GAPDH-catalyzed membrane fusion by authentic tubulin. Stopped-flow kinetic analysis demonstrated the high-affinity, rapid, and direct modulation of GAPDH-catalyzed fusion activity by tubulin. Because GTP-activated Rab 2 recruits GAPDH to membranes about to undergo fusion [Tisdale, E. J. (2001) J. Biol. Chem. 276, 2480-2486] and protein kinase Ciota/lambda phosphorylates GAPDH modulating its interactions with tubulin [Tisdale, E. J. (2001) J. Biol. Chem. 277, 3334-3341], the present study suggests a coordinated mechanism through which membrane trafficking and cellular signaling can be integrated with glycolytic flux.
Sagittal synostosis (2000)

Sagittal synostosis causes predictable malformations depending on the specific suture location that fuses. Anterior fusion causes frontal bossing, whereas posterior fusion causes an occipital knob. Complete sagittal synostosis results in deformity both anteriorly and posteriorly. Variants of each type exist and therefore surgical correction must be tailored to the individual patient. Examples of the different forms of sagittal synostosis are discussed, and the various surgical techniques available are detailed.
Functional Characterization of Human Methylenetetrahydrofolate Reductase in Saccharomyces cerevisiae (1999)

Human methylenetetrahydrofolate reductase (MTHFR, EC 1.5.1.20) catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. 5-Methyltetrahydrofolate is a major methyl donor in the remethylation of homocysteine to methionine. Impaired MTHFR can cause high levels of homocysteine in plasma, which is an independent risk factor for vascular disease and neural tube defects. We have functionally characterized wild-type and several mutant alleles of human MTHFR in yeast, Saccharomyces cerevisiae. We have shown that yeast MET11 is a functional homologue of human MTHFR. Expression of the human MTHFR cDNA in a yeast strain deleted for MET11 can restore the strain's MTHFR activity in vitro and complement its methionine auxotrophic phenotype in vivo. To understand the domain structure of human MTHFR, we have truncated the C terminus (50%) of the protein and demonstrated that expressing an N-terminal human MTHFR in met11(-) yeast cells rescues the growth phenotype, indicating that this region contains the catalytic domain of the enzyme. However, the truncation leads to the reduced protein levels, suggesting that the C terminus may be important for protein stabilization. We have also functionally characterized four missense mutations identified from patients with severe MTHFR deficiency and two common missense polymorphisms found at high frequency in the general population. Three of the four missense mutations are unable to complement the auxotrophic phenotype of met11(-) yeast cells and show less than 7% enzyme activity of the wild type in vitro. Both of the two common polymorphisms are able to complement the growth phenotype, although one exhibited thermolabile enzyme activity in vitro. These results shall be useful for the functional characterization of MTHFR mutations and analysis structure/function relationship of the enzyme.
Fault-tolerant ancilla preparation and noise threshold lower bounds for the 23-qubit Golay code (2011)

In fault-tolerant quantum computing schemes, the overhead is often dominated by the cost of preparing codewords reliably. This cost generally increases quadratically with the block size of the underlying quantum error-correcting code. In consequence, large codes that are otherwise very efficient have found limited fault-tolerance applications. Fault-tolerant preparation circuits therefore are an important target for optimization. We study the Golay code, a 23-qubit quantum error-correcting code that protects the logical qubit to a distance of seven. In simulations, even using a naive ancilla preparation procedure, the Golay code is competitive with other codes both in terms of overhead and the tolerable noise threshold. We provide two simplified circuits for fault-tolerant preparation of Golay code-encoded ancillas. The new circuits minimize error propagation, reducing the overhead by roughly a factor of four compared to standard encoding circuits. By adapting the malignant set counting technique to depolarizing noise, we further prove a threshold above 1.32 x 10^{-3} noise per gate.
A theoretical model for the covalent assembly of immunoglobulins. Application to the assembly of human immunoglobulin G in vitro. (1975)

A simple theoretical model for the formation of interchain disulfide bonds (covalent assembly) in immunoglobulins has been developed. This model successfully simulates the experimentally determined sequence of disulfide bond formation in vitro for human immunoglobulin G1 and G4 (Petersen, J. G. L., and Dorrington, K. J. (1974) J. Biol. Chem. 249, 5633-5641). The model appears to be generally applicable suggesting that the various pathways of covalent assembly observed in vivo and in vitro reflect structural differences between the immunoglobulin classes and subclasses. The rate of assembly, however, is dependent upon environmental factors.
Imaging molecular structure and physiological function of gap junctions and hemijunctions by multimodal atomic force microscopy (2001)

Gap junctions are specialized plasma membrane structures that join neighboring cells via specialized intercellular ion channels (hemichannels) and provide a direct pathway for cell-cell communication. They presumably mediate regulation of growth, transmission of developmental signals, coordination of muscle contraction, and maintenance of metabolic homeostasis. Hemichannels are also present in the non-junctional regions of the cell plasma membrane and they provide a direct pathway for communication between the cytoplasm and the extracellular region. Recent studies suggest that gap junctional communication is much more complex than previously anticipated, in terms of both its structure as well as its activity. While the mechanism of gap junction activity is being studied extensively, their quaternary structure, assembly, and conformational changes underlying gating of their activity as well as their physiological role are poorly understood because, due to their complex structure, these junctions are less amenable to existing techniques for high-resolution three-dimensional structure-function analyses. Atomic Force Microscopy (AFM) images molecular structure of biological specimens in an aqueous environment, allows on-line perturbations, and can be coupled with electrophysiological, biochemical, and other microscopic techniques. The present review examines the potential of AFM application for the study of the molecular structure of hydrated, native gap junctions and hemijunctions as well as their physiological functions. Special attention is paid to new, complementary, or provocative findings from AFM studies of both vertebrate and invertebrate gap junctions and hemijunctions.

Liquid Jet Pumps for Two-Phase Flows (1995)

Isothermal compression of a bubbly secondary fluid in a mixing-throat and diffuser is described by a one-dimensional flow model of a liquid-jet pump. Friction-loss coefficients used in the four equations may be determined experimentally, or taken from the literature. The model reduces to the liquid-jet gas compressor case if the secondary liquid is zero. Conversely, a zero secondary-gas flow reduces the liquid-jet gas and liquid (LJGL) model to that of the familiar liquid-jet liquid pump. A “jet loss” occurs in liquid-jet pumps if the nozzle tip is withdrawn from the entrance plane of the throat, and jet loss is included in the efficiency equations. Comparisons are made with published test data for liquid-jet liquid pumps and for liquid-jet gas compressors. The LJGL model is used to explore jet pump responses to two-phase secondary flows, nozzle-to-throat area ratio, and primary-jet velocity. The results are shown in terms of performance curves versus flow ratios. Predicted peak efficiencies are approximately 50 percent. Under severe operating conditions, LJGL pump performance curves exhibit maximum-flow ratios or cut-offs. Cut-off occurs when two-phase secondary-flow streams attain sonic values at the entry of the mixing throat. A dimensionless number correlates flow-ratio cut-offs with pump geometry and operating conditions. Throat-entry choking of the secondary flow can be predicted, hence avoided, in designing jet pumps to handle two-phase fluids.
Article (2002)

Spray-drying is a rapid dehydration method allowing production of high quality dairy powders. In dehydration and subsequent powder handling and storage, however, both chemical and physical changes, such as caking, lactose crystallisation, and nonenzymatic browning, may impair powder characteristics and result in loss of powder quality. Many of these changes are related to the physical state of lactose, as rapid removal of water in spray drying results in the formation of lowmoisture, amorphous, noncrystalline structures of lactose and other milk components. The amorphous components may exist as solid-like glasses or highly supercooled, viscous liquids. The formation of amorphous, glassy lactose during spray drying allows production of a free-flowing powder. High temperatures or residual water contents at the later stages of the drying process, however, may cause stickiness, caking, browning, and adhesion of the powder particles to the processing equipment. The glass transition of amorphous lactose occurs in the vicinity of room temperature at a water content of about 6.8 g (g 100) -1 of lactose corresponding to an equilibrium relative humidity of 37% and 0.37 a w (water activity). At higher water contents, as the glass transition of amorphous lactose is well below storage temperature, dairy powders become sticky and the amorphous lactose may exhibit time-dependent crystallisation. Crystallisation of amorphous lactose may also release sorbed water from the amorphous material, which enhances other deteriorative changes, such as the nonenzymatic browning reaction. Amorphous lactose in dairy powders encapsulates milk fat, which, as a result of lactose crystallisation, is released and becomes susceptible for rapid oxidation. The glass transition and water activity are, therefore, important factors controlling processability, handling properties and stability of dairy powders.
Some spiro analogs of the potent analgesic ketobemidone (1980)

A series of spiro analogues of the potent narcotic ketobemidone have been prepared and found to be devoid of opiate activity. Additional pharmacology and possible implications for the mode of binding of ketobemidone to the analgesic receptor are discussed.
Study of Location-based Routing Techniques of BS and Sensor Node (2012)

Abstract Routing technique of wireless sensor network that is presented to improve effectiveness of consumption in energy at the previous study is existing in various ways, however for routing, its own location data and nodes' location data close to with 1-hop distance should be kept. And it uses multi-hop transmission method that transmits data to BS node via several nodes. This technique makes electronic consumption of sensor node and entire network's energy consumption so that it makes effective energy management problem. Therefore, this paper suggests location based 1-hop routing technique of BS node that satisfies distance  ±α with source node using RSSI and radio wave range of sensor node.

Current management of cancer-associated anorexia and weight loss. (2001)

Loss of appetite and weight predict a poor prognosis for cancer patients. Although caloric supplementation might benefit subgroups of patients--specifically, perioperative, severely malnourished cancer patients, stem cell and bone marrow transplant patients and head and neck cancer patients--its use remains controversial and is not recommended for the majority of patients with cancer-associated weight loss. Most patients with advanced cancer, anorexia, and/or weight loss do not appear to benefit from nutritional supplementation. Instead, discussions with patients and families about realistic eating goals ans, at time armacologic interventions with progestational agents or corticosteroids--both of which are aimed at palliating anorexia--provide clinical benefit. Other phamalogic interventions such as eicosapentaenoic acid, thalidomide (Thalomid), adenosine triphosphate and nonsteriodal anti-inflammatory agents focus on the fact that cancer-assciated weight loss is an enitty dintinct for simple starvation These interventions promise to replenish lean tissue but require further investigation before they can be recommndedas standard clinical practice.
COMPRESSIVE SENSING IN QUADRATURE FREQUENCY MODULATED THERMAL WAVE IMAGING (2020)

Active thermography uses IR camera to capture the thermal response from a test sample to detect defects in the materials. Depending on the material geometry, externally Quadrature Frequency Modulated (QFM) optical stimulation consisting of very low frequency components usually less than 1 HZ is projected on the test sample. IR camera captures the thermal response from test material at a frequency much higher than the required nyquist rate. This is wastage of resources such as sensors, memory and power. In this paper Compressive Sensing (CS) is used to capture the thermal response from aluminum and bone test samples using IR camera at a reduced frame rate and then complete response is recovered using CS recovery algorithms Basis Pursuit (BP) and Orthogonal Matching Pursuit (OMP). Recovered thermal response is processed using correlation based pulse compression approach to perform subsurface analysis to detect the defects. To verify the effectiveness of the recovery algorithms comparison is done between original and recovered data and the results are promising.
Latent Semantic Kernels (2000)

Kernel methods like Support Vector Machines have successfully been used for text categorization. A standard choice of kernel function has been the inner product between the vector-space representationoftwo documents, in analogy with classical information retrieval (IR) approaches. Latent Semantic Indexing (LSI) has been successfully used for IR purposes as a technique for capturing semantic relations between terms and inserting them into the similarity measure between two documents. One of its main drawbacks, in IR, is its computational cost. In this paper we describe how the LSI approach can be implemented in a kernel-de ned feature space. We provide experimental results demonstrating that the approach can significantly improve performance, and that it does not impair it.
