Development of a Health Monitoring Capability for FRP Using Optical Fiber Sensors (2001)

Abstract Fiber reinforced polymers (FRP) are an efficient and relatively inexpensive method of repairing or replacing deteriorating and damaged infrastructure. FRP sheets can be applied to spalling bridge sections to prevent further deterioration and increase stiffness. Pre-fabricated FRP decks can also be used to replace weak portions of the bridge superstructure. However, the effect of the environment on long-term durability of FRP and how the various mechanisms of deterioration initiate and develop are not known. Systems for health monitoring are being sought as a means of managing transportation structures as assets in light of modern life cycle cost concepts. This paper will describe the efforts to develop a method to monitor the structural integrity of FRP materials utilizing an optical fiber sensor developed by Luna Innovations. This sensor is capable of detecting both transient, acoustic emission strain events as well as the accumulated strain in the components to which it is attached. The fact that this sensor is impervious to electromagnetic radiation makes it ideal for monitoring FRP in transportation applications.

These results suggest that the polymers are well accepted by the tissue and remain stable during the entire study period, and that they could be very suitable materials for use in nasal reconstruction.
Dissection of strain difference in acquired protective immunity against Mycobacterium bovis Calmette-Guérin bacillus (BCG). Macrophages regulate the susceptibility through cytokine network and the induction of nitric oxide synthase (1995)

Protection against infection with intracellular pathogens operates in two stages, early innate resistance and late acquired protective immunity (API), in inbred mouse strains. Although both C57BL/10 (B10) and BALB/c mice bear the susceptible phenotype of innate resistance, Calmette-Guérin bacillus (BCG) vaccination generated efficient API in B10 but not in BALB/c mice. Employing a specific nitric oxide (NO) synthase inhibitor, we revealed that NO production plays a pivotal role in the API of B10 mice. Consistent with this, expressions of the inducible isoform of NO synthase (iNOS) protein and mRNA were significantly higher in the spleen of B10 mice than in that of BALB/c mice. Furthermore, IFN-gamma, a potent inducer of iNOS, and mRNAs for IL-12 (p40); an inducer of IFN-gamma and IL-2 were also vigorously expressed in the spleen of B10 mice compared with that of BALB/c mice. In an attempt to clarify the mechanism by which the different capacities for API are generated, we analyzed the cytokine network between T cells and macrophages in both B10 and BALB/c mice. We found that multiple functions of macrophages, which include capacities to express IL-12 (p40) mRNA in response to BCG and to express mRNAs for iNOS and IL-12 (p40) in response to IFN-gamma, were impaired in BALB/c mice as compared with B10 mice. However, T cells appeared to express comparable level of IFN-gamma mRNA in both strains when stimulated with IL-12. Taken together, these results indicate that the macrophage functions play a pivotal role in both the induction and effector phases of API to determine the susceptibility of mice to BCG infection.
A compact magnetic bearing for gimballed momentum wheel (1983)

A three axis controlled magnetic bearing and its application to a momentum wheel are described. The four divided stators provide a momentum wheel with high reliability, low weight, large angular momentum storage capacity, and gimbal control. Those characteristics are desirable for spacecraft attitude control.
A structural motif that defines the ATP-regulatory module of guanylate cyclase in atrial natriuretic factor signalling (1992)

Atrial natriuretic factor (ANF)-dependent guanylate cyclase is a single-chain transmembrane-spanning protein, containing an ANF receptor and having catalytic activity. ANF binding to the receptor domain activates the catalytic domain, generating the second messenger cyclic GMP. Obligatory in this activation process is an intervening step regulated by ATP, but its mechanism is not known. Through a programme of site-directed and deletion mutagenesis/expression studies, we report herein the identity of a structural motif (Gly503-Arg-Gly-Ser-Asn-Tyr-Gly509) that binds ATP and amplifies the ANF-dependent cyclase activity; this, therefore, represents an ATP-regulatory module (ARM) of the enzyme, which plays a pivotal role in ANF signalling.
Extreme Thrombocytosis in Trauma Patients: Are Antiplatelet Agents the Answer? (2009)

The purpose of this study was to review the incidence of extreme thrombocytosis (ExT) (platelet count 1,000,000/microL or greater) in trauma patients and to examine the role of antiplatelet agents in its treatment. The Los Angeles County Medical Center trauma registry was used to obtain injury demographics, medications, and daily platelet counts for injured patients 16 years of age or older admitted between July 2005 and February 2008. Of 6,985 total trauma patients admitted during the study period, 95 developed ExT (1.4%). Average age was 29 years (range, 16-63 years), 89 per cent were male, 44 per cent had penetrating trauma, and mean Injury Severity Score was 24 (range, 1-57). Of the 95 patients with ExT, 41 were treated with aspirin (43%) and 54 were not (57%). The two groups did not differ with regard to basic demographics, injury patterns, vitals on admission, or splenectomy rate (34 vs 20%, P = 0.13). After adjusting for maximum platelet counts and duration of ExT, there was no difference between the treated and untreated groups in terms of mortality, complications, and intensive care unit or hospital lengths of stay. The incidence of ExT is approximately 1.4 per cent in trauma patients. Antiplatelet therapy does not affect ExT patient outcome. Further prospective studies are warranted.

INTERSTITIAL CELL STIMULATING HORMONE I. BIOLOGICAL PROPERTIES1<sup>1</sup> (1940)

THE SECRETION by the pituitary of two hormones with specific effects on the I gonadshas been recognized for some time. While the properties of one of these, the substance stimulatingovarian follicular development (FSH), have been sufficiently characterized, no such general agreement has been reached regarding the other component. Fevold has described the isolation of a luteinizing hormone, “LH” (i). This sub- stance either alone or in combination with FSH (the latter is the more recent opinion of the author (2)) increases the weights of testes and accessories in immature normal and hypophysectomized male rats and may be measured by its effect on the seminal vesicles; another method of assay suggested by this author is based on his finding that LH in combination with FSH very strikingly increases the ovarian weights over those produced by FSH alone, an effect called “augmentation.”
Extraverted Children Are More Biased by Bowl Sizes than Introverts (2013)

Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz) than in smaller (12-oz) bowls, whereas introverted children were unaffected by bowl size (+5.6%, ns). However, when children were asked by adults how much cereal they wanted to eat, both extraverted and introverted children requested more cereal when given a large versus small bowl. Insofar as extraverted children appear to be more biased by environmental cues, this pilot study suggests different serving styles are recommended for parents and other caregivers. They should serve extraverts, but allow introverts to serve themselves. Still, since the average child still served 23.2% more when serving themselves than when served by an adult, it might be best for caregivers to do the serving whenever possible--especially for extraverted children.
Spatial Domain Digital Watermarking of Multimedia Objects for Buyer Authentication (2004)

Most of the existing watermarking processes become vulnerable when the attacker knows the watermark insertion algorithm. This paper presents an invisible spatial domain watermark insertion algorithm for which we show that the watermark can be recovered, even if the attacker tries to manipulate the watermark with the knowledge of the watermarking process. The process incorporates buyer specific watermarks within a single multimedia object, and the same multimedia object has different watermarks that differ from owner to owner. Therefore recovery of this watermark not only authenticates the particular owner of the multimedia object but also could be used to identify the buyer involved in the forging process. This is achieved after spatially dividing the multimedia signal randomly into a set of disjoint subsets (referred to as the image key) and then manipulating the intensity of these subsets differently depending on a buyer specific key. These buyer specific keys are generated using a secret permutation of error correcting codes so that exact keys are not known even with the knowledge of the error correcting scheme. During recovery process a manipulated buyer key (due to attack) is extracted from the knowledge of the image key. The recovered buyer key is matched with the exact buyer key in the database utilizing the principles of error correction. The survival of the watermark is demonstrated for a wide range of transformations and forging attempts on multimedia objects both in spatial and frequency domains. We have shown that quantitatively our watermarking survives rewatermarking attack using the knowledge of the watermarking process more efficiently compared to a spread spectrum based technique. The efficacy of the process increases in scenarios in which there exist fewer numbers of buyer keys for a specific multimedia object. We have also shown that a minor variation of the watermark insertion process can survive a "Stirmark" attack. By making the image key and the intensity manipulation proms specific for a buyer and with proper selection of error correcting codes, certain categories of collusion attacks can also be precluded.
Ion-Exchange Chromatographic Determination of Hypoglycin A in Canned Ackee Fruit (1989)

Abstract An ion-exchange chromatographic method was developed to determine hypoglycin A (HG-A) levels in canned ackee fruit by using an amino acid analyzer. HG-A was extracted by homogenizing the sample in 80% alcohol. An isocratic buffer system, consisting of 30% sodium citrate buffer (pH 3.15) and 70% sodium chloride-sodium acetate buffer (pH 7.40) was used to obtain baseline separation between HG-A and the other amino acids. The system can detect HGA levels as low as 4.8 μg/mh. HG-A levels in the edible portion of fruit in 6 cans ranged from 11.0 to 66.5 mg HG-A/can. Recoveries by standard addition averaged 102.5%.
Evaluation of Gas Chromatography–Combustion–Isotope Ratio Mass Spectrometry (GC-C-IRMS) for the Quality Assessment of Citrus Liqueurs (2012)

Citrus liqueurs are alcoholic beverages obtained by maceration. The European Parliament protects these alcoholic beverages, forbidding the addition of nature-identical flavoring substances. However, for economical and technological reasons, producers often add natural and/or synthetic flavors to the alcoholic syrup, obtaining artificial spirit drinks. The aim of this study is to investigate the authenticity of Italian liqueurs, of lemon, bergamot, and mandarin (locally known as "limoncello", "bargamino", and "mandarinetto"), comparing the carbon isotope ratios with values determined in genuine cold-pressed peel oils. Authenticity assessment was performed using headspace-solid phase microextraction coupled to gas chromatography-combustion-isotope ratio mass spectrometry. Additional analyses were performed by direct enantioselective gas chromatography to determine the enantiomeric distribution of selected chiral volatiles and by gas chromatography-mass spectrometry for the qualitative analyses of the samples. The method allowed confirmation of genuineness. Enantioselective gas chromatography analyses confirmed the results, demonstrating the reliability of the method.
Expression of α<sub>2</sub>‐macroglobulin receptor/low density lipoprotein receptor‐related protein is increased in reactive and neoplastic glial cells (1994)

alpha 2-Macroglobulin receptor/low density lipoprotein receptor-related protein (alpha 2M-R/LRP) is a multi-functional cell-surface receptor that has been implicated in diverse physiologic processes. In normal human brain, alpha 2M-R/LRP is expressed principally by pyramidal neurons with localization to cell bodies and proximal processes. By contrast, alpha 2M-R/LRP is not present in either the cell bodies or processes of most normal macroglia (including astrocytes). In this investigation, we studied the expression of alpha 2M-R/LRP in the brain, following tissue injury or neoplastic transformation, by immunohistochemistry. Significantly increased alpha 2M-R/LRP immunoreactivity was identified in reactive astrocytes, indicating the expression of this receptor is regulated in vivo in response to brain injury. alpha 2M-R/LRP immunoreactivity was also detected in glial cell tumors; this finding is novel since malignant transformation is typically thought to turn off expression of this receptor.
CATALYST EFFECT ON THE SYNTHESIS OF ETHYL ACETATE VIA REDUCTIVE CARBONYLATION OF METHYL ACETATE (1982)

Abstract The effect of several catalysts and binary catalyst mixtures is examined in the formation of ethyl acetate from methyl acetate in presence of CO–H2. The most effective catalytic system is a combination of ruthenium-cobalt compounds. The optimum conversion and selectivity to ethyl acetate is achieved with an atomic ratio Co/Ru = 0.4.
Got Annoyed? Examining the Advertising Effectiveness and Annoyance Dynamics (2017)

This study captures the trade-off between effective and annoying display advertising. We propose a hidden Markov model that allows us to investigate the enduring impact of display advertising on consumers' purchase decisions and the potential of persistent display advertising to stimulate annoyance in consumers. Additionally, we study the structural dynamics of these display advertising effects by allowing the corresponding effects to be contingent on the latent state of the funnel path in which consumers reside. Our findings demonstrate a tension exists between generating interest and triggering annoyance in consumers; whereas display advertising has an enduring impact on transitioning consumers further down in the funnel path, display-advertising exposures beyond a frequency threshold can have an adverse effect by increasing the probability that consumers will be annoyed. Investigating the dynamics of annoyance, we reveal that consumers who reside in different stages of the funnel path exhibit considerably different tolerance for annoyance stimulation.
Usage-based dhcp lease time optimization (2007)

The Dynamic Host Configuration Protocol (DHCP) is used to dynamically allocate address space to hosts on a local area network. Despite its widespread usage, few studies exist on DHCP usage patterns, and even less is known about the importance of setting the lease time (the time that a client retains ownership over some IP address) to an appropriate value. Lease time can greatly affect the tradeoff between address space utilization and the number of both renewal messages and client session expirations. In this paper, using a DHCP trace for 5 weekdays from the Georgia Tech campus network, we present the largest known study of DHCP utilization. We also explore how various strategies for setting lease times can dramatically reduce the number of renewals and expirations without prohibitively increasing address space utilization.
Technological Aspects of Solid-State and Incandescent Sources for Miner Cap Lamps (2008)

Light emitting diodes (LEDs) are emerging as viable replacements for incandescent-based cap lamps used in mining. The photometric and energy characteristics of these light sources differ in important ways. The present paper describes the performance of LED and incandescent sources in cap lamps in terms of correlated color temperature, color rendering, light output, electric power, ambient temperature and airflow, and light source aging. Importantly, these characteristics can influence a miner's ability to spot mining hazards thus impacting safety. Secondly, some of these characteristics interact with the operating life of the cap lamp's battery power, such that differences between LED and incandescent sources can be magnified toward the end of a 10- hour battery discharge cycle. Empirically, we have determined that after 8 hours at an ambient temperature of 25degC, the average light output of an incandescent cap lamp can decrease to about 69% of its initial value when powered by a lead-acid battery and it can decrease to about 65% of its initial value when powered by a nickel-hydride battery. An LED-based cap lamp using a constant current drive circuit can maintain about 96% of its initial value when powered by a nickel-hydride battery. Real-world tests addressing the effects of ambient temperature and airflow on the light output of an LED and incandescent cap lamp were conducted in the NIOSH Safety Research Coal Mine (SRCM). The LED cap lamp yielded a vertical average illuminance improvement of approximately 9.5% and the INC cap lamp yielded a vertical average illuminance degradation of approximately 4%. The differences between LED and incandescent cap lamps were further quantified by the calculation of "mesopic luminance" data that indicated for the same photopic luminance (i.e., as measured using a conventional light meter) the LED cap lamp could be up to 38% more efficient than the incandescent cap lamp with a lead-acid battery at the end of the 10-hour driving cycle. Lastly, accelerated life tests were used to empirically determine light output depreciation as the incandescent light source age approached its useful life. There was about a 35% decrease in light output. This is quite considerable, especially given that the light output will decrease an additional 30% to 45% over the period of a 10-hour shift. The implications of the differences between LED and incandescent sources are discussed. This information is crucial in determining how visual performance could be affected for real-world conditions where batteries discharge during the work shift and as the light source ages. To date, only idealized conditions have been used for LED and incandescent cap lamp visual performance research.
Changing patterns in the association between regional socio-economic context and dental caries experience according to gender and age: A multilevel study in Korean adults (2012)

The results of this study indicated that socio-economic factors affecting residents' dental health status may operate through different mechanisms or degrees according to geographic location, suggesting that some gender- and age-defined subgroups may be likely to benefit from different types of intervention, including the development of specific health policies.
Amylose-lipid complex formation during single-screw extrusion of various corn starches. (1994)

Commercial corn starches containing 0-70% amylose were extruded with and without various lipids (myristic, stearic, and behenic acids; monoglyceride Dimodan PV; and tristearin) in a single-screw laboratory extruder at 110 o C, 110 rpm, 19% moisture, and 4% lipid. X-ray diffractograms, iodine-binding capacity, and iodine spectrum of the soluble fractions of the extrudates were determined. Additions of fatty acids and monoglyceride resulted in V-patterns in X-ray diffractograms and decreased iodine-binding capacity of the extruded starches, indicating formation of complexes between amylose and lipids. Maximum binding was observed for myristic acid and 70% amylose starch. No binding was observed with tristearin. Physico-chemical properties of starches (expansion ratio, water-soluble carbohydrates, and water-solubility index) decreased. Bulk density increased upon addition of complexing lipids before extrusion. These properties reached limiting values as the percentage of complexed amylose increased above 20, 15, and 10% for 25, 50, and 70% amylose starches, respectively
Contrast MRA segmentation to predict hemodynamical outcome in renal patients (2009)

Arteriovenous fistulae (AVF) are utilized to connect the circulation of renal disease patients to hemodialysers. AVF creation is hampered by high complication rates [1]. We try to initiate a paradigm shift towards predictive medicine, by developing patient-specific 1D models to simulate the hemodynamic effect of AVF creation. Image Segmentation The vessel centerline was detected by wave front propagation, starting from one user seeding point (most proximal artery, Fig.3 left). Second order image derivatives restricted the segmentation to the lumen. The vessel contour was detected perpendicular to the l l li b F ll 1D Model
WFDC2 (HE4): A potential role in the innate immunity of the oral cavity and respiratory tract and the development of adenocarcinomas of the lung (2006)

We believe that these studies support the hypothesis that WFDC2 may be a component of the innate immune defences of the lung, nasal and oral cavities and suggest that WFDC2 functions in concert with related WAP domain containing proteins in epithelial host defence. We also suggest that WFDC2 re-expression in lung carcinomas may prove to be associated with tumour type and should be studied in further detail.
Microwave performance of AlGaN/GaN high electron mobility transistors on Si(111) substrates (2003)

The first AlGaN/GaN high electron mobility transistors (HEMTs) on silicon substrates have been realized using Organometallic Vapor Phase Epitaxy (OMVPE). Static output characteristics with low output conductance and isolation approaching 80 V were observed on devices fabricated on 1 /spl Omega/-cm p-Si(111). At microwave frequencies, a capacitively coupled substrate charge limits the device performance, resulting in a 25 GHz cutoff frequency and 0.5 W/mm output power for 0.3 /spl mu/m gate length devices. A small-signal equivalent circuit incorporating elements representing the parasitic loading from the substrate accurately models the capacitive coupling effect observed on measured S-parameters.
