Development of a Multipurpose Mobile Robot for Concrete Surface Processing (1992)

This paper reports on the continuing design of an autonomous multipurpose mobile robot intended for concrete slab finishing, grinding, and cleaning during construction. Common to these three applications are rotating tools in contact with the floor. Selectively adaptable to one machine, these tools will perform recurrent tasks on a construction site. In Phase 1, an experimental vehicle has been built to test navigation concepts including path planning, location measurement, and path following. Steering and locomotion of the experimental vehicle are provided by two independently steered and powered wheel sets enabling the vehicle to perform complex manoeuvres required by the selected application. In Phase 2, a robot prototype equipped with tools is under development. Different vehicle-tool configurations have been modelled and simulated in order to attain optimal mobility and surface coverage.
Le réveil des cardiomyocytes adultes résidents (2012)

All cardiomyopathies and more specifically myocardial infarction always evolve to cardiomyocytes death and the ensuing heart failure setting. So far, cardiac regenerative medicine has focused on the use of stem cells and completely ignored the resident cardiomyocytes, assumed in a postmitotic state. However, recent findings in zebrafish and mammalians challenge this view and suggest that these cells have some capacity to proliferate and can contribute to heart regeneration. In this review, we propose an overall synthesis about knowledge of the proliferative and regenerative capacities of resident cardiomyocytes, dealing with some mechanistic aspects. In the future, the accurate identification of molecular mechanisms allowing wake-up of resident cardiomyocyte proliferation will certainly open new therapeutic avenues in cardiac regeneration.
The correlation functions of rbm and m/m/1 (1988)

This paper describes the (auto) correlation functions of regulated or reflecting Brownian motion (RBM) and several processes associated with the M/M/1 queue. For RBM and the M/M/1 continuous-time queue-length process, the correlation function of the stationary process coincides with the complementary stationary-excess cdf (cumulative distribution function) associated with a previously studied first-moment cdf. The first-moment cdf is the mean as a function of time given that the process starts at the origin, normalized by dividing by the steady-state limit. The M/M/1 first-moment cdf in turn is the stationary-excess cdf associated with the M/M/1 busy-period cdf. In fact, all the moment cdfs and correlation functions can be expressed directly in terms of the busy-period cdf. This structure provides the basis for simple approximations of the correlation functions and the moments as functions of time by hyperexponentials.
Soybeans and Other Oilseeds (2000)

Abstract The four principal U.S. oilseed crops are soybeans, cottonseed, peanuts, and sunflower seed. The physical characteristics of the plants and seeds, chemical compositions of the seeds, harvesting and storage of the crops, and processing of the crops into oil and defatted meal are described for the primary products of the industry. Production figures and prices of the oilseeds and their products are presented. The oils of these crops are used primarily for human consumption. Minor quantities go into industrial products. The defatted meals serve mainly as protein sources in animal feeds, but small amounts are processed into protein ingredients used by the food industry. Nutritional properties and antinutritional factors of the oils and meals are reviewed. Direct food uses of soybeans, peanuts, and sunflower seed are also covered.
Preparation of PbS Quantum Dot Materials by the Sol-Gel Process (1993)

Quantum dot materials based on PbS-doped sodium borosilicate glasses were prepared by the sol-gel process using silicon methoxide (TMOS), boron ethoxide, sodium and lead acetates as starting materials. The chemical state of Pb species in the glasses fully densified at 590°C was identified to be PbS by X-ray photoelectron spectroscopy and electron diffraction. The amount of PbS crystallites in the glasses was 4-13wt% of mother glasses. The size of the crystallites was 5-15nm in diameter. The absorption edge of the glasses was near 2500nm, which was slightly shifted to higher energy from 3200nm for the bulk PbS crystal.

FIRST-PRINCIPLES SIMULATION OP GAS-PHASE DDT AND THE EFFECTS OF HOT-SPOT FORMATION (2002)

A series of multidimensional numerical simulations were used to investigate how a turbulent deflagration may undergo a transition into a detonation, the process of deflagration-to-detonation transition (DDT). The reactive Navier-Stokes equations were solved on an adaptive mesh that resolved selected features of the flow including the structure of the laminar flame. The chemical and thermophysical models used reproduced the flame and detonation properties of acetylene in air over a range of temperatures and pressures. The interactions of an incident shock with the initially laminar flame lead to the formation of secondary shocks, rarefactions, contact surfaces, and boundary layers that continued to distort the flame surface, eventually creating a turbulent flame-brush. Pressure fluctuations were shown to be the seeds for hot spots in unreacted material. These hot spots undergo transitions to detonations when the gradients in induction time in the hot spot allowed the formation of supersonic spontaneous waves. This paper begins the process of examining the special effects of boundary layers generated by flames, shocks, and their interactions.

The Prothrombin Gene (1986)

Using recombinant DNA techniques, DNA fragments coding for bovine prothrombin mRNA have been cloned and characterized. Structural studies have revealed that prothrombin mRNA encodes a precursor protein having an amino-terminal extension of 43 amino acid residues. Using bovine prothrombin cDNA as a hybridization probe, the genes coding for human and bovine prothrombin have been isolated and partially characterized. The organization of the prothrombin gene is similar, but not identical to the organization of the genes coding for the other vitamin-K-dependent clotting factors.
Direct data-driven control of linear parameter-varying systems (2013)

In many control applications, nonlinear plants can be modeled as linear parameter-varying (LPV) systems, by which the dynamic behavior is assumed to be linear, but also dependent on some measurable signals, e.g., operating conditions. When a measured data set is available, LPV model identification can provide low complexity linear models that can embed the underlying nonlinear dynamic behavior of the plant. For such models, powerful control synthesis tools are available, but the way the modeling error and the conservativeness of the embedding affect the control performance is still largely unknown. Therefore, it appears to be attractive to directly synthesize the controller from data without modeling the plant. In this paper, a novel data-driven synthesis scheme is proposed to lay the basic foundations of future research on this challenging problem. The effectiveness of the proposed approach is illustrated by a numerical example.
Gadd45 is a novel mediator of cardiomyocyte apoptosis induced by ischaemia/hypoxia (2010)

These results suggest that Gadd45beta is a key player in ischaemia/hypoxia-induced apoptotic cardiomyocyte death, and that strategies based on its inhibition might be of benefit in the treatment of acute ischaemic heart disease.
MAC Centered Cooperation — Synergistic Design of Network Coding, Multi-Packet Reception, and Improved Fairness to Increase Network Throughput (2012)

We design a cross-layer approach to aid in developing a cooperative solution using multi-packet reception (MPR), network coding (NC), and medium access (MAC). We construct a model for the behavior of the IEEE 802.11 MAC protocol and apply it to key small canonical topology components and their larger counterparts. The results obtained from this model match the available experimental results with fidelity. Using this model, we show that fairness allocation by the 802.11 MAC can significantly impede performance; hence, we devise a new MAC that not only substantially improves throughput, but provides fairness to flows of information rather than to nodes. We show that cooperation between NC, MPR, and our new MAC achieves super-additive gains of up to 6.3 times that of routing with the standard 802.11 MAC. Furthermore, we extend the model to analyze our MAC's asymptotic and throughput behaviors as the number of nodes increases or the MPR capability is limited to only a single node. Finally, we show that although network performance is reduced under substantial asymmetry or limited implementation of MPR to a central node, there are some important practical cases, even under these conditions, where MPR, NC, and their combination provide significant gains.
Bioactivities of Glycoalkaloids and Their Aglycones from Solanum Species (2011)

Potatoes, tomatoes, and aubergines are all species of the Solanum genus and contain a vast array of secondary metabolites including calystegine alkaloids, phenolic compounds, lectins, and glycoalkaloids. Glycoalkaloids have been the subject of many literature papers, occur widely in the human diet, and are known to induce toxicity. Therefore, from a food safety perspective further information is required regarding their analysis, toxicity, and bioavailability. This is especially important in crop cultivars derived from wild species to prevent glycoalkaloid-induced toxicity. A comprehensive review of the bioactivity of glycoalkaloids and their aglycones of the Solanum species, particularly focused on comparison of their bioactivities including their anticancer, anticholesterol, antimicrobial, anti-inflammatory, antinociceptive, and antipyretic effects, toxicity, and synergism of action of the principal Solanum glycoalkaloids, correlated to differences of their individual molecular structures is presented.
Staufen1 links RNA stress granules and autophagy in a model of neurodegeneration (2018)

Spinocerebellar ataxia type 2 (SCA2) is a neurodegenerative disease caused by expansion of polyglutamine tract in the ATXN2 protein. We identified Staufen1 (STAU1) as an interactor of ATXN2, and showed elevation in cells from SCA2 patients, amyotrophic lateral sclerosis (ALS) patients, and in SCA2 mouse models. We demonstrated recruitment of STAU1 to mutant ATXN2 aggregates in brain tissue from patients with SCA2 human brain and in an SCA2 mouse model, and association of STAU1 elevation with dysregulation of SCA2-related transcript abundances. Targeting STAU1 in vitro by RNAi restored PCP2 transcript levels and lowering mutant ATXN2 also normalized STAU1 levels. Reduction of Stau1 in vivo improved motor behavior in an SCA2 mouse model, normalized the levels of several SCA2-related proteins, and reduced aggregation of polyglutamine-expanded ATXN2. These findings suggest a function for STAU1 in aberrant RNA metabolism associated with ATXN2 mutation, suggesting STAU1 is a possible novel therapeutic target for SCA2.
Optimizing Resource Utilization of a Data Center (2016)

To provision IT solutions with reduced operating expenses, many businesses are moving their IT infrastructures into public data centers or are starting to build their own private data centers. Data centers can provide flexible resource provisioning in order to accommodate the workload demand. In this paper, we present a comprehensive survey of most relevant research activities on resource management of data centers that aim to optimize the resource utilization. We first describe the resource overprovisioning problem in current data centers. Then, we summarize two important components in the resource management platform and present the benefit of accurately predicting the workload in resource management. Afterwards, we classify existing resource management in a data center into three categories: 1) virtual machine-based, 2) physical machine-based, and 3) application-based resource management mechanisms. We discuss the performance degradation for implementing these three kinds of resource management in a heterogeneous data center. Finally, we present three important issues arose in the data center resource management and some potential approaches to address the issues. This paper presents a timely survey on resource management in a data center, and provides a comprehensive reference for further research in this field.
Blowout Prevention and Relief-Well Planning for the Wheatstone Big-Bore Gas-Well Project (2017)

Summary The offshore Wheatstone liquefied natural gas (LNG) project in Western Australia uses subsea big-bore gas wells as the preferred method of producing the field. Wheatstone wells use a 9⅝-in. production conduit from the top of the gas pay zone to the ocean floor. Wellbores of this size are necessary to match the large productive capacity of the gas reservoirs they penetrate. This producing scenario provides the obvious benefit of yielding large volumes of gas through the use of relatively few wells. Each of those highly productive wells, however, also represents a source of gas that, if accidentally allowed to flow unhindered, could present an uncommonly difficult well-control challenge. It is for this reason that the Wheatstone Drilling and Completions (D&amp;C) Team evaluated a wide range of possible reservoir- and well-architecture scenarios to fully understand the possible scale of relief-well responses that might be necessary in the event of a blowout. The conclusions from this evaluation were surprising. Our original well-design concept called for penetrating the Wheatstone gas reservoirs with a casing shoe set 3,100 ft vertically above. Our analysis indicated that three or four relief wells would be simultaneously required to bring a blowout under control. Because of these results, both the well- and drilling-execution plan were redesigned to minimize the number of required relief wells. In summary, the redesign amounted to setting the casing immediately (i.e., ≤ 10 ft) above the gas reservoir before actually penetrating it, with the resulting benefit of reducing the required number of relief wells to two. Although this reduction is beneficial, it should be noted that there is only one documented subsea case where two or more relief wells have been drilled with the intent of simultaneously pumping into both to effect a dynamic kill. Given this fact, our well-control-related preparations for executing this project were more extensive than those of preceding projects. This paper chronicles the full extent of the engineering and operational planning performed to ensure that no uncontrolled hydrocarbon releases occurred during the execution of the Wheatstone Project's subsea big-bore gas wells and, if a blowout were to occur, that the response to such an unprecedented event would be sufficient and robust. Covered in this paper are reservoir-deliverability modeling, dynamic-kill modeling, gas-plume modeling, relief-well trajectory and mooring planning, pilot-hole-execution planning, a newly applied logging-while-drilling (LWD) technology for sensing resistivity vertically below the drill bit, and a discussion of future research identified as necessary to better define the fluid-injectivity capabilities of subsea relief wells.
Dielectric properties and spatial distribution of polarization in polyethylene aged under ac voltage in a humid atmosphere (1998)

This paper reports the results of an investigation of the dielectric properties, growth of water tree density and spatial distribution of polarization in samples of non-stabilized LDPE. Samples were initially sand-blasted to accelerate initiation of water trees, and subsequently aged in salt solution for approximately three weeks under two regimes of temperature (room temperature and 65/spl deg/C). Aging both with and without the presence of electric field stress was studied. The capacitance and dielectric loss of each sample were measured using a HV capacitance bridge, and compared to theoretical models over the frequency range 10/sup -5/ to 10/sup 4/ Hz. The results indicate a real movement of charges/ions in the polymer bulk which causes a deterioration of the electrical insulation properties even in the absence of AC fields. The presence of a field further degrades the insulator. Samples were studied using the LIMM (laser-intensity-modulation method) to determine the distribution of polarization, assuming mean polarization is zero and space charge is absent. In the absence of the external field there is a presence of ionic charges of opposite polarity, which increases with increasing aging time and is highest at room temperature. The length of the twenty longest vented water trees was measured after various aging times, and it was found that trees grown at room temperature are longer than those grown at 65/spl deg/C. Also, the tree density was higher in specimens tested at room temperature.
Acupuncture versus ondansetron in the prevention of postoperative vomiting. A study of children undergoing dental surgery (2001)

This study compares the anti-emetic effect of acupuncture with that of ondansetron and a placebo. Ninety children undergoing dental treatment under general anaesthesia were randomly allocated to one of the three equal groups, to receive acupuncture needle insertion, intravenous ondansetron 0.15 mg x kg(-1) or a placebo. Parental satisfaction scores and the incidence of emetic episodes were recorded. A significant difference was found in the number of patients who vomited and the total number of the emetic episodes when comparing the two treatment groups with the placebo group (p < 0.0001). A significant difference was also found between the treatment groups and the placebo group with respect to parental satisfaction score (p < 0.03). We conclude that traditional Chinese acupuncture is a valid non-pharmacological alternative anti-emetic treatment that can be recommended as a prophylactic technique in children undergoing dental surgery under general anaesthesia.
Effect of anterior capsule polishing on the posterior capsule opacification–inhibiting properties of a sharp-edged, 3-piece, silicone intraocular lens (2006)

Three years after cataract surgery, eyes in which the anterior capsule had been polished had significantly less ACO. However, polishing did not lower PCO intensity when a sharp-edged CeeOn 911A IOL was implanted in the bag. Although results indicate that anterior capsule polishing may enhance the development of regeneratory PCO, this trend did not reach statistical significance.
Highly Magnetized Encoded Hydrogel Microparticles with Enhanced Rinsing Capabilities for Efficient microRNA Detection (2021)

Encoded hydrogel microparticles mounting DNA probes are powerful tools for high-performance microRNA (miRNA) detection in terms of sensitivity, specificity, and multiplex detection capability. However, several particle rinsing steps in the assay procedure present challenges for rapid and efficient detection. To overcome this limitation, we encapsulated dense magnetic nanoparticles to reduce the rinsing steps and duration via magnetic separation. A large number of magnetic nanoparticles were encapsulated into hydrogel microparticles based on a discontinuous dewetting technique combined with degassed micromolding lithography. In addition, we attached DNA probes targeting three types of miRNAs related to preeclampsia to magnetically encoded hydrogel microparticles by post-synthesis conjugation and achieved sensitivity comparable to that of conventional nonmagnetic encoded hydrogel microparticles. To demonstrate the multiplex capability of magnetically encoded hydrogel microparticles while maintaining the advantages of the simplified rinsing process when addressing multiple samples, we conducted a triplex detection of preeclampsia-related miRNAs. In conclusion, the introduction of magnetically encoded hydrogel microparticles not only allowed efficient miRNA detection but also provided comparable sensitivity and multiplexed detectability to conventional nonmagnetic encoded hydrogel microparticles.
