Vibration Analysis Using Extrinsic Fabry-Perot Interferometric Sensors and Neural Networks (2002)

An Extrinsic Fabry-Perot interferometric (EFPI) sensor attached to a vibrating structure will see a sinusoidal strain. Harmonic analysis on this strain yields well defined harmonics. Strain level measurement, on a periodically-actuated-instrumented structure, can provide information about the health of that structure. This approach can form a smart health monitoring system for composite structures. A simple demodulation system employing artificial neural networks (ANN) was used to extract harmonics and predict the maximum strain level on a smart composite beam. This paper deals with the computer simulation of the sinusoidal strain and implementation of the demodulation system. The system employs two back-propagation neural networks. The frost network extracts the harmonics from the strain profile and the second predicts the strain levels through harmonic analysis extracted.

The kinetics of condensation and evaporation of H2O from pure ice in the range 173–223 K: a quartz crystal microbalance study (2004)

The kinetics of evaporation and condensation on ice condensed from the vapor phase at 190 K has been studied in the range 173–223 K using a suitably calibrated quartz crystal microbalance that was put inside a vacuum chamber that could be used either as a molecular or a stirred flow reactor, depending on the measured pumping speed. The Arrhenius representation of the zero order evaporative flux Jev (molecule cm−2 s−1) displays a discontinuity at 193 ± 2 K that could be observed owing to the degree of precision of the present measurements. For 223 > T > 193 K, Jev = (1.6 ± 0.7) × 1028exp((−10.2 ± 0.5)/RT) molecule cm−2 s−1and for 173 < T < 193 K, Jev = (2.2 ± 0.9) × 1030exp((−12.0 ± 0.5)/RT) molecule cm−2 s−1 where R = 1.987 × 10−3 kcal mol−1 K−1. The corresponding measured rate constant kcond for H2O condensation on ice satisfies the known vapor pressure Peq (H2O) together with Jev thereby affording thermochemical closure of the kinetics which results in the heat of sublimation ΔHsubl0 = 11.7 ± 0.6 and 12.3 ± 0.5 kcal mol−1 from the above high and low T-range, respectively. Jev is significantly lower than the maximum theoretically allowed value throughout the T-range in agreement with an uptake coefficient for H2O on ice that is significantly smaller than unity. In addition, the negative temperature dependence of kcond or γ reveals a precursor-mediated adsorption/desorption process for the H2O/ice system. The increased evaporative lifetime of pure ice may be important under atmospheric conditions.
Identification of EZH2 as a Molecular Marker for a Precancerous State in Morphologically Normal Breast Tissues (2006)

The discovery of molecular markers to detect the precancerous state would have profound implications in the prevention of breast cancer. We report that the expression of the Polycomb group protein EZH2 increases in histologically normal breast epithelium with higher risk of developing cancer. We identify EZH2 as a potential marker for detecting preneoplastic lesions of the breast in vivo and as a possible target for preventative intervention.
Abstract 1300: Breast cancer-associated macrophages undergo proliferation at different rates across ethnicities: results of a pilot study (2015)

Abstract The tumor microenvironment is a complex biosystem composed of diverse cells, including tumor, immune and non-immune stromal cells. It has become increasingly clear that stromal cells have critical roles in tumor progression. Among the immune stromal cells, tumor-associated macrophages (TAM) are found in abundance, playing critical roles in tumor progression and are signs of poor prognosis. Whereas in chronic inflammation of a tissue M1 pro-inflammatory macrophages may play a role in tumor initiation, in advanced tumors, TAMs promote anti-inflammatory functions including suppression of immunity, tumor invasion, angiogenesis, metastasis, and resemble the behavior of M2 anti-inflammatory macrophages. CD163 is considered a human pan macrophage marker and has been extensively used in TAMs recognition in human tumors. Until recently, macrophages were considered end-differentiated cells without mitotic activity. However, more recently proliferative activity of macrophages has been identified in several settings, but not in tumors. In a recent study, we demonstrated that breast cancers from different ethnicities exhibit diverse degree of TAMs colonization. African American (AA) and Latina (LA) patients present with more aggressive tumors and lower survival rates than Caucasian (CA) women. We recently demonstrated that AA breast cancer patients exhibit tumors with very high numbers of macrophages, followed by LA, with CA showing the lowest numbers of TAMs. Consequently, in the present study we sought to examine whether the high numbers of TAMs detected in these cancer health disparity groups were associated with macrophage capacity to proliferate. To assess TAM mitotic potential, the Ki-67 nuclear marker was used. To examine this question, we carried out a pilot study with a small number of cases where the co-expression levels of Ki-67 and CD163 were determined by immunofluorescence (IF) in sections of human breast cancers from a retrospective breast cancer tumor bank encompassing these three ethnicities. Our results reveal that tumors from AA patients contain the highest numbers of CD163+/Ki-67+ cells among the three ethnic groups, followed by LA, with CA exhibiting the lowest numbers, thus paralleling our results with TAM numbers in these same ethnicities. As far as we know, this is the first report of macrophage proliferation in a tumor microenvironment, and particularly in association with ethnicity cancer disparity groups. Citation Format: Lidia G.

Synthese totale de k 13 (inhibiteur de l'e. C. A. ) et de ra vii (anticancereux) ; developpement d'un nouveau reactif de transfert du groupe triflate : le triflate de 4-nitrophenol (1998)

Mon travail de these a eu pour but de developper une nouvelle methode de formation de la liaison biarylether capable de repondre a plusieurs criteres : necessite de conditions douces ; rendements eleves ; possibilite d'appliquer cette methode de maniere intramoleculaire, afin de realiser la macrocyclisation par formation de la liaison biarylether. Dans la premiere partie nous avons montre que le systeme o-fluoronitroaryle subit l'attaque d'un phenolate pour conduire au biarylether correspondant avec des rendements de l'ordre de 80 %. La version intramoleculaire nous a permis de realiser la fermeture du macrocycle a 17 chainons de k 13 avec des rendements superieurs a 80 % et sans qu'il soit necessaire d'operer dans des conditions de haute dilution. Nous avons ainsi pu realiser une synthese totale tres efficace de k 13. Nous avons decouvert que lorsqu'un substrat contient deux fonctions phenol de reactivite equivalente, seul le macrocycle desire meta-para cyclophane a 17 chainons est forme aux depens du macrocycle para-para cyclophane a 18 chainons, une propriete inherente a la reaction intramoleculaire. Dans la seconde partie, nous avons realise la synthese du motif structural cycloisodityrosine, macrocycle a 14 chainons faisant partie de la structure de ra vii. Des problemes d'epimerisation ayant ete rencontres, nous avons du changer de strategie par changement de position du groupe nitro, ce qui nous a conduit a une synthese tres efficace de la cycloisodityrosine. Ici encore, nous avons observe que seul le macrocycle regioisomere meta-para cyclophane a 14 chainons est produit et une tentative d'explication de cette selection a ete proposee sur la base de calculs de modelisation moleculaire. Avec cette voie de synthese efficace de la cycloisodityrosine, nous avons par la suite realise la synthese totale de ra vii. Dans la troisieme partie, nous avons developpe un nouveau reactif de transfert du groupement triflate sur les phenols : le triflate de 4-nitrophenol.
Flow measurement with a double acoustic time-reversal mirror (1996)

Acoustic time-reversal invariance is broken when the propagating medium contains a flow. This effect is taken advantage of to achieve a new way of characterizing the vorticity field of a flow with a double time-reversal mirror (TRM). The double TRM is made up of two transducer arrays surrounding the flow. The time-reversal process is performed between the two arrays: When one array emits, the other one receives, time-reverses, and re-emits the acoustic wave. In the absence of flow, time-reversal invariance insures that many back and forth propagations between the two arrays do not modify the emitted wavefront. In the presence of flow, the acoustic wavefront is distorted through the flow. This distortion is related to the amplitude and size of the vorticity field and is often too small after one crossing to be observed experimentally. In order to amplify this wavefront distortion, several back and forth propagations are imposed on the acoustic wave through the flow between the two arrays. The greater number of crossings through the vorticity field induces an amplification of the effect of vorticity on the acoustic wavefront. This effect can then be easily measured and provides the vorticity characteristics even for flow with a small vorticity field.

Plasma levels of soluble glycoprotein VI (sGPVI) are associated with ischemic stroke (2012)

Platelet collagen receptor glycoprotein VI (pGPVI) is elevated in patients with acute coronary syndrome (ACS) and ischemic stroke. Recently, we developed a novel bead-based sandwich immunoassay to determine soluble GPVI (sGPVI), which has been validated in ACS patients. This study aimed to evaluate the plasma levels of sGPVI and pGPVI expression in patients with suspected stroke. We consecutively evaluated 176 patients, who were admitted to the stroke unit. Surface expression of pGPVI was determined by flow cytometry, sGPVI concentrations were determined using our sandwich immunoassay. Unlike patients with TIA, patients with stroke showed significantly decreased plasma levels of sGPVI compared to patients with non-ischemic (NI) events (TIA: mean [µg/L] ± standard deviation): 6.1 ± 2.1 vs. NI: 8 ± 4; p = 0.192; stroke: 5.9 ± 2.3 vs. NI; p = 0.013), whereas for pGPVI, patients with TIA and ischemic stroke revealed a significantly increased platelet surface expression compared to NI patients (TIA: mean fluorescence intensity [MFI] ± standard deviation): 20.9 ± 5.4 vs. NI: 17.6 ± 5.2; p = 0.021; stroke: 20.3 ± 6.2 vs. NI; p = 0.016). Using logistic regression analysis, both sGPVI (p = 0.002) and pGPVI (p = 0.012) are independently associated with ischemic stroke compared to other laboratory markers. To predict the individual risk for ischemic stroke using the plasma levels of sGPVI, receiver operating characteristic (ROC) analysis determined an optimal cutoff value of sGPVI at 6.5 µg/l, thus, patients with decreased plasma levels (<6.5 µg/l) have a 1.5-fold adjusted odds ratio (95%confidence interval, 1.4-2.7). Lower plasma levels of sGPVI are associated with the slightly elevated risk of stroke and may be a promising novel biomarker.
Air stable high resolution organic transistors by selective laser sintering of ink-jet printed metal nanoparticles (2007)

A high resolution organic field effect transistor (OFET) fabrication process has been developed based on the selective laser sintering of ink-jet printed nanoparticle inks and the recent development of an air stable carboxylate-functionalized polythiophene semiconducting polymer. The entire fabrication and device characterization are performed at room temperature, ambient pressure, and air environment without using complex lithographic methods. This low temperature OFET fabrication process based on nanoparticle laser sintering has great potential for realizing inexpensive, large area flexible electronics on heat sensitive polymer substrates.

Dense Depth Posterior (DDP) From Single Image and Sparse Range (2019)

We present a deep learning system to infer the posterior distribution of a dense depth map associated with an image, by exploiting sparse range measurements, for instance from a lidar. While the lidar may provide a depth value for a small percentage of the pixels, we exploit regularities reflected in the training set to complete the map so as to have a probability over depth for each pixel in the image. We exploit a Conditional Prior Network, that allows associating a probability to each depth value given an image, and combine it with a likelihood term that uses the sparse measurements. Optionally we can also exploit the availability of stereo during training, but in any case only require a single image and a sparse point cloud at run-time. We test our approach on both unsupervised and supervised depth completion using the KITTI benchmark, and improve the state-of-the-art in both.
If-what analysis for data center transformations (2011)

Data center operators strive to meet various objectives such as improve end-user experience, plan infrastructure to support business volumes, mitigate risk, reduce cost, etc. Given the large scale, heterogeneity, and complexity of today's data centers, deriving recommendations for meeting such objectives is a very challenging task. We argue that to provide such recommendations, if-what analysis has become a pressing need of today's data-center operators. We formulate the problem of if-what analysis and present various design issues and challenges in building this solution.
Large-Scale Selective Functionalization of Alkanes (2017)

Great progress has been made in the past several decades concerning C-H bond functionalization. But despite many significant advances, a commercially viable large-scale process for selective alkane functionalization remains an unreached goal. Such conversions will require highly active, selective, and long-lived catalysts. In addition, essentially complete atom-economy will be required. Thus, any reagents used in transforming the alkanes must be almost free (e.g., O<sub>2</sub>, H<sub>2</sub>O, N<sub>2</sub>), or they should be incorporated into the desired large-scale product. Any side-products should be completely benign or have value as fuels (e.g., H<sub>2</sub> or other alkanes). Progress and promising leads toward the development of such systems involving primarily molecular transition metal catalysts are described.

How to Win the Clone Wars: Efficient Periodic n-Times Anonymous Authentication. (2006)

Abstract We create a credential system that lets a user anonymously authenticate at most n timesin a single time period. A user withdraws a dispenser of n e-tokens. She shows an e-token toa verifier to authenticate herself; each e-token can be used only once, however, the dispenser automatically refreshes every time period. The only prior solution to this problem, due toDamg*ard et al. [30], uses protocols that are a factor of k slower for the user and verifier, where kis the security parameter. Damg*ard et al. also only support one authentication per time period, while we support n. Because our construction is based on e-cash, we can use existing techniquesto identify a cheating user, trace all of her e-tokens, and revoke her dispensers. We also offer a new anonymity service: glitch protection for basically honest users who (occasionally) reuse e-tokens. The verifier can always recognize a reused e-token; however, we preserve the anonymity of users who do not reuse e-tokens too often. 1 Introduction As computer devices get smaller and less intrusive, it becomes possible to place them everywhere and use them to collect information about their environment. For example, with today&amp;apos;s technology, sensors mounted on vehicles may report to a central traffic service which parts of the roads are treacherous, thus assisting people in planning their commutes. Some have proposed mounting sensors in refrigerators to report the consumption statistics of a household, thus aiding in public health studies, or even mounting them in people&amp;apos;s bodies in an attempt to aid medical science. In all these areas, better information may ultimately lead to a better quality of life.
Molecular dynamics simulation of the kinetic sintering of Ni and Al nanoparticles (2009)

The kinetic sintering of Ni and Al nanoparticles is considered using molecular dynamics simulations. We report on the effects of nanoparticle size on sintering temperature and time, with results showing that surface energy has a slight effect on both results. The effect of surface energy on combustion temperature is limited to nanoparticles of less than 10 nm in diameter. An analysis of the various alloys formed during sintering gives insight into the reaction process. The formation of Al-rich compounds is observed initially with a final equilibration and rapid formation of the eutectic alloy immediately preceded by melting of the Ni nanoparticle. We have observed that nanoparticle size and surface energy are both important factors in determining the adiabatic reaction temperature for this material system at nanoparticle sizes of less than 10 nm in diameter.
The impact of dialysis on the survival of patients with immunoglobulin light chain (AL) amyloidosis undergoing autologous stem cell transplantation (2015)

The study found significant differences in the OS depending on when the acute renal failure occurred. Patients who required dialysis within 30 days of ASCT had the highest rate of TRM. Screening with serum albumin and eGFR may reduce the risk.
A high resolution two‐dimensional gel electrophoresis and silver staining protocol demonstrated with nuclear matrix proteins (1990)

An improved two-dimensional gel electrophoresis procedure has been developed utilizing isolated nuclear matrix proteins. The proteins of the cellular nuclear matrix are tissue specific. They are an example of a protein set whose two-dimensional electrophoretic patterns afford much information of clinical significance. However, current two-dimensional gel techniques were not completely satisfactory for the small amounts of protein present in tissue samples. There was a need for a two-dimensional gel procedure which was capable of increased sensitivity and resolution and at the same time was reliable and reproducible. This has been accomplished by implementing several modifications to the current two-dimensional gel procedures. In addition, changes were introduced in the silver staining process of the gels to increase the signal to background ratio. The overall procedure affects a dramatic increase in the resolution and clarity of the proteins visualized on two-dimensional gels and is no more laborious than current techniques.
Delay line with different receiver-resonator channels as an all mechanical front-end of a discrete matched filter for wake-up radios (2018)

We present the conceptual approach, theoretical simulations, and experimental results of a new radio frequency mechanical signal processor composed of a delay line with one transmitter and several receivers integrated with resonators. The system allows to set different delays and voltage gains for every receiver-resonator subsystem (channel), hence enabling processing of discrete chirp signals or complex frequency-shift keying (FSK) signals. We show results for a 2-channel system. The experimental results show voltage gain and different delay for each channel. This all-mechanical signal processor is ideal for improving signal-to-noise ratio in low-power wake-up radio receivers.
