QoS-Aware Video Transmission Over Hybrid Wireless Network for Connected Vehicles (2017)

Communication between vehicles enables a wide array of applications and services ranging from road safety to traffic management and infotainment. Each application places distinct quality of service (QoS) constraints on the exchange of information. The required performance of the supported services differs considerably in terms of bandwidth, latency, and communication reliability. For example, high-bandwidth applications, such as video streaming, require highly reliable communication. However, the attenuation of the IEEE 802.11p/DSRC communication link, due to static and mobile obstructing objects, degrades the link quality and can compromise the QoS requirements of the supported applications. On the other hand, a dual-interface hybrid architecture may have a failover or backup mechanism and benefit from more reliable alternatives, such as cellular networks for occasionally offloading data transmission by radio access technology (RAT) selection and vertical handover process. Since 4G/Long-Term Evolution (LTE) is generally not free, it is, therefore, highly desirable to minimize the time during which the cellular interface is used and to return to the IEEE 802.11p/DSRC interface. This paper proposes a hybrid communication approach based on 4G/LTE and the IEEE 802.11p technologies to support a V2X video streaming application. The proposed approach includes details on the underlying communication architecture, a procedure for selecting the best RAT, a real test platform complemented by a standard software protocol stack, and finally an extensive performance evaluation of the proposed solution based on field test measurements. The results indicate that the proposed approach significantly improves the overall reliability of communication with respect to packet and frame delivery metrics.
Precessional switching of a 3×1 micrometer elliptical element in a crossed-wire geometry (2004)

Switching dynamics of a thin-film 3×1 micrometer elliptical permalloy element in a crossed-wire geometry was investigated for different pulsed field amplitudes using time resolved scanning Kerr microscopy. We observed coherent switching of magnetization by fast-risetime hard axis magnetic field pulses. The combined action of easy- and hard-axis fields resulted in reliable half-select switching of the sample magnetization. Varying the delay between the pulses one can control the postswitching oscillations of magnetization or eliminate them altogether achieving an ultrafast half-select switching of risetime of just 180 ps. Our results agree quantitatively with Landau–Lifshitz–Gilbert-based micromagnetic simulations.
BRCA1 Inhibits Membrane Estrogen and Growth Factor Receptor Signaling to Cell Proliferation in Breast Cancer (2004)

BRCA1 mutations and estrogen use are risk factors for the development of breast cancer. Recent work has identified estrogen receptors localized at the plasma membrane that signal to cell biology. We examined the impact of BRCA1 on membrane estrogen and growth factor receptor signaling to breast cancer cell proliferation. MCF-7 and ZR-75-1 cells showed a rapid and sustained activation of extracellular signal-related kinase (ERK) in response to estradiol (E2) that was substantially prevented by wild-type (wt) but not mutant BRCA1. The proliferation of MCF-7 cells induced by E2 was significantly inhibited by PD98059, a specific ERK inhibitor, or by dominant negative ERK2 expression and by expression of wt BRCA1 (but not mutant BRCA1). E2 induced the synthesis of cyclins D1 and B1, the activity of cyclin-dependent kinases Cdk4 and CDK1, and G(1)/S and G(2)/M cell cycle progression. The intact tumor suppressor inhibited all of these. wt BRCA1 also inhibited epidermal growth factor and insulin-like growth factor I-induced ERK and cell proliferation. The inhibition of ERK and cell proliferation by BRCA1 was prevented by phosphatase inhibitors and by interfering RNA knockdown of the ERK phosphatase, mitogen-activated kinase phosphatase 1. Our findings support a novel tumor suppressor function of BRCA1 that is relevant to breast cancer and identify a potential interactive risk factor for women with BRCA1 mutations.
Colocalization of SCD1 and DGAT2: implying preference for endogenous monounsaturated fatty acids in triglyceride synthesis (2006)

Stearoyl-coenzyme A desaturase (SCD) is an endoplasmic reticulum (ER) protein that catalyzes the Delta9-cis desaturation of saturated fatty acids. Mice with targeted disruption in SCD1 (Scd1(-/-)) have significant reduction in the tissue content of triglycerides, suggesting that monounsaturated fatty acids endogenously synthesized by SCD1 are important for triglyceride synthesis. Acyl-coenzyme A:diacylglycerol acyltransferase (DGAT) is the enzyme that catalyzes the final reaction in the synthesis of triglycerides. The lack of DGAT2, one of the two DGAT isoforms, results in almost a complete loss of tissue triglycerides. We hypothesize that SCD1 participates in triglyceride synthesis by providing a more accessible pool of monounsaturated fatty acids through substrate channeling. In this study, we test whether SCD1 is proximal to DGAT2 by colocalization study with confocal microscopy, coimmunoprecipitation, and fluorescence resonance energy transfer using HeLa cells as the model of study. All of the results suggest that SCD1 and DGAT2 are located very close to each other in the ER, which is a very important criterion for the channeling of substrate. By performing subcellular fractionation using mouse livers, we also show, for the first time, that SCD is present in the mitochondria-associated membrane.
Adaptive multisensor data fusion for acoustic emission source localization in noisy environment (2012)

This article proposes an adaptive multisensor fusion algorithm for acoustic emission source location in isotropic plate-like structures in noisy environments. Overall, the approach consists of the following four main stages: (a) feature extraction, (b) sensor selection based on a binary hypothesis testing, (c) sensor weighting based on a well-defined reliability function, and (d) estimation of the acoustic emission source location based on the extended Kalman filter. The performance of the proposed algorithm is validated through pencil lead breaks performed on an aluminum plate instrumented with a sparse array of piezoelectric sensors. Two experimental setups have been used to simulate a highly noisy environment. In the first setup, the experimental signals have been artificially corrupted with different levels of noise generated by a Monte Carlo simulation. In the second setup, two piezoelectric transducers have been used to continuously generate high-power white noise during testing. The results show the capability of the proposed algorithm for inflight structural health monitoring of metallic aircraft panels in highly noisy operational situation.
Rider assistance system with an active safety mechanism (2015)

This paper discusses on the design and use of emerging technologies to provide a rider assistance system with an integrated safety mechanism for two wheelers (2W). This paper identifies the most frequent causes of two wheeler accidents and how the rider interacts with the vehicle during the pre-crash phase and vehicle behavior by analyzing the two wheeler accident data. Rider Assistance System (RAS) shall identify the existing technologies and safety systems in passenger cars and assess their usability or with modifications in two wheelers. This system shall continuously monitor the approaching path for any stationary or moving obstacles. And also monitors the rider's field of vision for any deviation from the intended path. These inputs shall be achieved either by range sensor based technology or/and a computer vision based technology. These input parameters shall be processed by an Electronic Control Unit (ECU) to take an autonomous decision to avoid a crash or to warn the rider to take an action. The autonomous decision shall be de-accelerating the vehicle by intervening the rider's acceleration inputs. With this autonomous action of the system, a possible crash shall be prevented ensuring rider's safety.
Health-related quality of life and its determinants in patients with metastatic renal cell carcinoma (2017)

Key drivers for reduced HRQoL in mRCC are disease symptoms. Since symptoms increase with progression of disease, targeted therapies that increase PFS are expected to postpone reductions in HRQoL in mRCC.
Diagnosis and treatment of dementia: 6. Management of severe Alzheimer disease (2008)

Severe Alzheimer disease requires frequent monitoring by health professionals. Simple nonpharmacologic approaches may address problems with mood and agitation. Antipsychotic drug therapy is occasionally necessary despite the inherent risks. Therapy with a cholinesterase inhibitor and memantine may be useful for selected patients.
Diagnosis code assignment: models and evaluation metrics (2013)

Hierarchy-based classification yields better ICD9 coding than flat classification for MIMIC patients. Automated ICD9 coding is an example of a task for which data and tools can be shared and for which the research community can work together to build on shared models and advance the state of the art.

Round Window Electrocochleography Just Before Cochlear Implantation (2013)

ECoGs with high signal-to-noise ratios can be recorded from almost all implant candidates, including both adult and pediatric populations. In postlingual adults, the ECoG magnitude is more predictive of implant outcomes than other nonsurgical variables such as duration of deafness or degree of residual hearing.
Power saving strategy for an UWB impulse radio transceiver using PCTH (2003)

Pseudo-chaotic time hopping (PCTH) is a recently proposed coding/modulation scheme for UWB (ultrawide band) impulse radio. PCTH exploits concepts from symbolic dynamics to generate aperiodic spreading sequences. In this paper we present a power saving strategy for a multi-access UWB system based on PCTH. It is shown that our approach leads to a significant power saving. The trade-off with respect to BER performance is also discussed.

Effect of cysteine mutagenesis on human IgE reactivity of recombinant forms of the major rye grass pollen allergen Lol p 1 (2003)

Hypersensitivity to the group 1 grass pollen allergens is a significant causative factor in the onset of symptoms for hay fever sufferers. To better understand the IgE reactivity of the group 1 allergen from rye grass pollen, we sought to disrupt potential conformational IgE epitopes on recombinant (r) Lol p 1 by the specific replacement of the seven cysteine residues in the protein sequence. Site-directed mutagenesis on the Lol p 1 coding sequence was used to replace all seven cysteine residues with serine residues. rLol p 1 and the seven cysteine variants generated by this method were tested for comparative human IgE reactivity via western blot immunoscreening and densitometry. Alteration of the cysteine residues at amino acid positions 72, 77, 83 and 139 of rLol p 1 was found to reduce the human IgE binding potential of the molecule. However, the most consistent reduction in human IgE reactivity was demonstrated by replacement of C77; human IgE antibodies showed an average 62.7% reduction in reactivity to this molecule. The present investigation has shown that at least one of the cysteine residues within the Lol p 1 protein contributes to the IgE binding properties of this allergen.
1-Carbazolyl Spirobifluorene: Synthesis, Structural, Electrochemical, and Photophysical Properties (2019)

The present work reports one of the rare examples of a new emerging family of spirobifluorene derivatives, namely, 1-substituted spirobifluorenes. We report the synthesis and the structural, electrochemical, and photophysical properties of 9-(9,9′-spirobi[fluorene]-1-yl)-9H-carbazole 1-Cbz-SBF, constructed from the connection of the widely known electron-rich carbazole fragment at the C1 position of spirobifluorene. We show with 1-Cbz-SBF that the substitution at C1 induces two important characteristics which drive the electronic properties. First, there is a complete π-conjugation breaking between the pending substituent, herein, carbazole, and the substituted fluorene. Second, there is a through-space interaction between the carbazole and its cofacial fluorene. Thanks to a structure–property relationship approach with its constituting building blocks 9,9′-spirobifluorene SBF and carbazole Cbz, we show how some electronic properties are driven by the carbazole unit such as the highest occupied molecular orbital energy level, whereas others are driven by the fluorene unit such as the triplet-state energy level. As 1-substituted spirobifluorenyl represents a new and promising molecular scaffold for phosphorescent organic light-emitting diode applications and more generally for organic electronics, such a study provides fundamental knowledge to design future organic materials for specific applications.
Pilot clinical study to evaluate the anticoagulant activity of fucoidan (2009)

Seaweed-derived heparin-like substances such as fucoidan have been extensively studied in vitro as potential blood anticoagulants. However, there have been no human studies investigating the anticoagulant activity of fucoidan when administered orally. This pilot clinical trial was aimed to assess the safety and clinical effects of fucoidan ingestion on hemostasis as well as study its in-vitro anticoagulant activity. In a single-blinded clinical trial, a total of 20 human volunteers were allocated to both the placebo group (n = 10) who ingested 3 g of guar gum capsules and to the active treatment group (n = 10) who ingested 3 g of 75% fucoidan capsules for 12 days. Platelet indices, activated partial thromboplastin time, antithrombin-III, thrombin time, prothrombin time, and antifactor-Xa were analyzed according to standard methods. In vivo, activated partial thromboplastin time increased from 28.41 to 34.01 s (n = 10, P = 0.01), thrombin time decreased from 18.62 to 17.55 s (n = 10, P = 0.04), and antithrombin-III increased from 113.5 to 117% (n = 10, P = 0.03). The in-vitro fucoidan anticoagulant activity was found prominent. It increased activated partial thromboplastin time, thrombin time, and prothrombin time, whereas antithrombin-III decreased. In-vivo effect of fucoidan on hemostasis was not obvious probably due to low intestinal absorption. Thus, fucoidan in the form used in this study does not seem to have an oral anticoagulant activity, but it has a very strong in-vitro anticoagulant activity.
Quantitative Determination of Caffeine in Beverages Using a Combined SPME-GC/MS Method (1997)

Solid-phase microextraction (SPME) combined with gas chromatography/mass spectrometry (GC/MS) has been applied to the analysis of various caffeinated beverages. Unlike the current methods, this technique is solvent free and requires no pH adjustments. The simplicity of the SPME-GC/MS method lends itself to a good undergraduate laboratory practice. This publication describes the analytical conditions and presents the data for determination of caffeine in coffee, tea, and coke. Quantitation by isotopic dilution is also illustrated.
Polystyrene-<i>block</i>-poly(<i>n</i>-butyl acrylate)-<i>block</i>-polystyrene Triblock Copolymer Thermoplastic Elastomer Synthesized via RAFT Emulsion Polymerization (2010)

A series of well-controlled polystyrene-b-poly(n-butyl acrylate)-b-polystyrene triblock copolymers were prepared by emulsion polymerization with a carefully designed amphiphilic macroRAFT (reversible addition−fragmentation chain transfer) agent. The triblock copolymers were produced within four hours and only a few percent of dead chains were estimated. Tensile strength of the materials was a function of composition only and it increased linearly with polystyrene composition up to 50 wt %. The ultimate tensile strength reached 10 MPa with an elongation at break of 500% at the polystyrene composition of 40−50 wt %.
A Bio-Manipulation Method Based on the Hydrodynamic Force of Multiple Microfluidic Streams (2013)

This paper proposes a multiple microfluidic streambased manipulation (MMSM) system for bio-objects. It uses micro hydrodynamics and lab on chip (LOC) technology. Our method can implement the functions of micro manipulation and micro assembly of bio-objects in an open space without contact. Compared to other conventional bio-micro-manipulation and assembly methods, this system manipulates micro objects by controlling multiple microfluidic streams onto them from various directions. The advantages of this method are that it performs open space, multifunction, multi-scale, multi-degree-of-freedom, and non-invasive 3D manipulation. These microfluidic streams are generated simultaneously from multiple orifices. By regulating the parameters of the microfluidic stream, such as the position and number of operating orifices and the flow rate, the direction and velocity of the object can be controlled. To verify this principle, we design an open-space fluidic system for on-chip manipulation and calculated velocity and direction of the microfluidic stream using CFD simulation. Then the prototype microchip with an array of nine orifices is fabricated from glass. In experiments, demonstrations of rectilinear motion of a single cell andmicro particle are observed. The results presented in this paper show that this MMSM is capable of biomicromanipulation and micro assembly of bio-objects.

From Particle Acceleration to Impact and Bonding in Cold Spraying (2009)

In conventional thermal spraying, the spray particles are partially or fully molten when they deposit on the substrate. Cold spraying, in contrast, uses less thermal and more kinetic energy. In this process, solid particles impact on the substrate at high velocities and form excellent coatings. Due to comparatively low temperatures and typically inert process gases, cold spraying is particularly suitable for heat and oxidation sensitive materials. In recent years, modeling and computational methods have been widely used to study this relatively new spraying process, particularly to describe impact conditions of particles, to improve nozzle design, and to provide a better understanding of the thermo-mechanical processes that lead to particle bonding and deposition. This paper summarizes the state of the art in these theoretical studies, alongside a comprehensive description of the process. The paper also discusses the prediction of coating properties in the light of modeling combined with experimental investigations.
DataCell: Exploiting the Power of Relational Databases for Efficient Stream Processing (2009)

Designed for complex event processing, DataCell is a research prototype database system in the area of sensor stream systems. Under development at CWI, it belongs to the MonetDB database system family. CWI researchers innovatively built a stream engine directly on top of a database kernel, thus exploiting and merging technologies from the stream world and the rich area of database literature. The results are very promising.
Technologies and architectures for scalable dynamic dense WDM networks (2000)

Wavelength-division multiplexing has been recognized for a number of years as a promising and applied technology that can be used to increase the aggregate system bit rate. More attention has been given to devices and technologies that can be exploited to enable WDM to move from being a pure transmission technology into a state where it can be applied in transparent all-optical networks. In particular, devices and technologies such as wavelength routing switches, switched sources, tunable sources, tunable filters, and wavelength converters have all been developed and demonstrated. This article gives a description of the technologies, subsystems, and network architectures that rely on multiple wavelengths to achieve full transparent all-optical connectivity joined, in many instances, with features like scalability, modularity, and survivability. Exposure is also given to most of the current WDM demonstrators.
