Electrically-Assisted Formation and Desorption of Dodecyl Phosphate Self-Assembled Monolayers on Indium Tin Oxide Surfaces (2006)

Molecularly homogenous and hydrophobic surfaces play an important role in a number of technological applications such as tribology and protein/cellular adhesion. Self-assembled monolayers of dodecyl phosphates (DDPO4) have previously been demonstrated to spontaneously form on titanium oxide, producing surfaces with excellent hydrophobic properties. In this paper, we report on the adsorption of DDPO4 onto a transparent electronic material, indium tin oxide (ITO), under both open circuit and applied potential conditions. We have used two complementary surface characterization techniques: variable angle scanning ellipsometry and contact angle measurements to investigate the adsorption of DDPO4 on an ITO surface. Under open circuit condition, both methods consistently confirmed the formation of DDPO4 monolayers on the ITO surface. The presence of an electrical field increased the amount of DDPO4 adsorbed on the ITO surface. An applied anodic electrical stimulus of 1800 mV resulted in an exponential loss of the monolayer as confirmed by X-ray photoelectron spectroscopy and electrochemical optical waveguide lightmode spectroscopy (EC- OWLS). This electrically stimulated selective adsorption/desorption of DDPO4 opens up new ways to tailor the physico-chemical properties of surfaces.

StackVault: Protection from Untrusted Functions (2020)

Data exfiltration attacks have led to huge data breaches. Recently, the Equifax attack affected 147M users and a third party library - Apache Struts - was alleged to be responsible for it. These attacks often exploit the fact that sensitive data are stored unencrypted in process memory and can be accessed by any function executing within the same process, including untrusted third party library functions. This paper presents StackVault, a kernel-based system to prevent sensitive stack-based data from being accessed in an unauthorized manner by intra-process functions. Stack-based data includes data on stack as well as data pointed to by pointer variables on stack. StackVault consists of three components: (1) a set of programming APIs to allow users to specify which data needs to be protected, (2) a kernel module which uses unforgeable function identities to reliably carry out the sensitive data protection, and (3) an LLVM compiler extension that enables transparent placement of stack protection operations. The StackVault system automatically enforces stack protection through spatial and temporal access monitoring and control over both sensitive stack data and untrusted functions. We implemented StackVault and evaluated it using a number of popular real world applications, including gRPC. The results show that StackVault is effective and efficient, incurring only up to 2.4% runtime overhead.
An investigation of the conformational equilibrium of n-butane in a solvent using Raman spectroscopy (1982)

The trans-gauche energy difference for n-butane dissolved in CH2Cl2 and in CCl4 has been measured by the method of Raman band intensities. In methylene chloride, ΔE was observed to be 537±70 cal/mol, a value indistinguishable from that reported for pure liquid butane. A slightly lower value 438±80 cal/mol was observed for the CCl4 solution.
A tactile stress rate sensor for perception of fine surface features (2002)

The author reports the development of a new type of contact sensor for the measurement of fine surface features and textures down to the micron level. The sensor has a complicated rubber covering and is inexpensive and robust. As it is stroked across the surface of interest, piezoelectric transducers embedded in the sensor surface respond to stress induced by surface features. The sensor uses a current amplifier in place of the traditional charge amplifier, which eliminates many of the problems associated with piezoelectric transducers. The resulting signal is proportional to the rate of change of stress, or the stress rate. The signal can be interpreted with the aid of a solid mechanics model of the contact interaction and a linear deconvolution filter. The ability to detect features as small as a few micrometers has been experimentally confirmed. Intended applications include perception of surface properties to improve the robustness of robotic manipulation and rapid evaluation of surface finish in manufacturing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Electron-LO phonon scattering in Ga1-xInxNyAs1-y/GaAs quantum well (2013)

Within the framework of effective mass approximation, the values of energy eigenvalue En in Ga1-xInxNyAs1-y/GaAs quantum well are theoretically calculated using shooting method. In addition, we calculate the electron-LO phonon scattering and mean scattering rate at different temperatures, well width, N concentrations and In concentrations for an electron initially in the second subband and finally in the ground state using Fermi’s golden rule. It is shown that the electron-LO phonon scattering and mean scattering rate increase with the increase of N concentration under the In concentration constant. The electron-LO phonon scattering and mean scattering rate decrease with the increase of In concentration under the In concentration constant. The electron-LO phonon scattering increases monotonically with the increase of temperature. When the temperature is relatively low, the variation of mean scattering rate is not obvious with the increase of temperature When the temperature is relatively high, mean scattering rate increases with the increase of temperature. The scattering and mean scattering rate increase up to their maxima and then begin to decrease as the well width increases. The maximum value is reached when the well width is about 200 Å. Our calculated results are meaningful and can be used for designing the optoelectronic devices based on Ga1-xInxNyAs1-y/GaAs quantum well.
Tunable Dual-Wavelength Fiber Laser Using Optical-Injection Fabry–PÉrot Laser (2008)

In this investigation, we propose and experimentally demonstrate a dual-wavelength fiber laser based on a self-injected Fabry-Perot laser diode and an erbium-doped fiber. The dual-wavelength tuning range is 39.49 nm, from 1526.27 to 1565.76 nm. And the mode spacing of the dual-wavelength can be tuned from 1.32 to 39.49 nm. In addition, the output power difference of the dual-wavelength can be controlled and smaller than 1 dB.
Efficient sampling technique for optimization under uncertainty (1997)

Abstract The concept of robust design involves identification of design settings that make the product performance less sensitive to the effects of seasonal and environmental variations. This concept is discussed in this article in the context of batch distillation column design with feed stock variations, and internal and external uncertainties. Stochastic optimization methods provide a general approach to robust/parameter design as compared to conventional techniques. However, the computational burden of these approaches can be extreme and depends on the sample size used for characterizing the parametric variations and uncertainties. A novel sampling technique is presented that generates and inverts the Hammersley points (an optimal design for placing n points uniformly on a k‐dimensional cube) to provide a representative sample for multivariate probability distributions. The example of robust batch‐distillation column design illustrates that the new sampling technique offers significant computational savings and better accuracy.
Ultrafast compound imaging for 2D displacement vector measurements: application to transient elastography and color flow mapping (2002)

This paper presents a new technique for 2D imaging of the two-dimensional motion vector at a very high frame rate with ultrasound. Its potential is experimentally demonstrated for transient elastography. To date, only axial displacements induced in human tissues by low frequency vibrators were measured. This new technique allows us to follow both axial and lateral displacements during the shear wave propagation and thus should improve the Young's modulus image reconstruction. The process is a combination of several ideas well known in ultrasonic imaging: ultra-fast imaging, multi-synthetic aperture beamforming, 1D speckle tracking and compound imaging. Classical beamforming in the transmit mode is here replaced by a single plane wave illumination. The beamforming process is achieved only in the receive mode on two independent subapertures. Comparison of successive frames by a 1D speckle tracking algorithm allows to estimate displacements along two different directions linked to the sub-apertures beams. The variance of the deduced estimates is finally improved by tilting the emitting plane wave at each illumination. Beyond transient elastography, this technique could be of great interest for complex flows imaging.

Schnurri-3 regulates ERK downstream of WNT signaling in osteoblasts (2013)

Mice deficient in Schnurri-3 (SHN3; also known as HIVEP3) display increased bone formation, but harnessing this observation for therapeutic benefit requires an improved understanding of how SHN3 functions in osteoblasts. Here we identified SHN3 as a dampener of ERK activity that functions in part downstream of WNT signaling in osteoblasts. A D-domain motif within SHN3 mediated the interaction with and inhibition of ERK activity and osteoblast differentiation, and knockin of a mutation in Shn3 that abolishes this interaction resulted in aberrant ERK activation and consequent osteoblast hyperactivity in vivo. Additionally, in vivo genetic interaction studies demonstrated that crossing to Lrp5(-/-) mice partially rescued the osteosclerotic phenotype of Shn3(-/-) mice; mechanistically, this corresponded to the ability of SHN3 to inhibit ERK-mediated suppression of GSK3β. Inducible knockdown of Shn3 in adult mice resulted in a high-bone mass phenotype, providing evidence that transient blockade of these pathways in adults holds promise as a therapy for osteoporosis.
MPDCC Based High Efficiency Harmonic Reduction Control for IPMSM Driven by Electrolytic Capacitorless Inverter (2018)

In the electrolytic capacitorless inverter system, resonance occurs between the inductance on the grid side and the DC-link capacitor. Because of this resonance, the regulation of the input current harmonic may not be satisfied in some cases. In order to satisfy harmonic regulation, a method for controlling this input current by direct DC-link current control has been proposed using PWM modulation. In PWM modulation, the switching frequency depends on the carrier frequency. This paper proposes a control method that reduces the switching frequency and satisfies the harmonic regulation via model predictive direct current control (MPDCC). This paper is confirmed that the proposed method reduces harmonics of input current and switching frequency. The effectiveness of the proposed method is verified by numerical simulation.
Important Determinants for Fucoidan Bioactivity: A Critical Review of Structure-Function Relations and Extraction Methods for Fucose-Containing Sulfated Polysaccharides from Brown Seaweeds (2011)

Seaweeds--or marine macroalgae--notably brown seaweeds in the class Phaeophyceae, contain fucoidan. Fucoidan designates a group of certain fucose-containing sulfated polysaccharides (FCSPs) that have a backbone built of (1→3)-linked α-L-fucopyranosyl or of alternating (1→3)- and (1→4)-linked α-L-fucopyranosyl residues, but also include sulfated galactofucans with backbones built of (1→6)-β-D-galacto- and/or (1→2)-β-D-mannopyranosyl units with fucose or fuco-oligosaccharide branching, and/or glucuronic acid, xylose or glucose substitutions. These FCSPs offer several potentially beneficial bioactive functions for humans. The bioactive properties may vary depending on the source of seaweed, the compositional and structural traits, the content (charge density), distribution, and bonding of the sulfate substitutions, and the purity of the FCSP product. The preservation of the structural integrity of the FCSP molecules essentially depends on the extraction methodology which has a crucial, but partly overlooked, significance for obtaining the relevant structural features required for specific biological activities and for elucidating structure-function relations. The aim of this review is to provide information on the most recent developments in the chemistry of fucoidan/FCSPs emphasizing the significance of different extraction techniques for the structural composition and biological activity with particular focus on sulfate groups.
Fiber laser front ends for high-energy short pulse lasers (2005)

We are developing an all fiber laser system optimized for providing input pulses for short pulse (1-10ps), high energy (~1kJ) glass laser systems. Fiber lasers are ideal solutions for these systems as they are highly reliable and once constructed they can be operated with ease. Furthermore, they offer an additional benefit of significantly reduced footprint. In most labs containing equivalent bulk laser systems, the system occupies two 4’x8’ tables and would consist of 10's if not a 100 of optics which would need to be individually aligned and maintained. The design requirements for this application are very different those commonly seen in fiber lasers. High energy lasers often have low repetition rates (as low as one pulse every few hours) and thus high average power and efficiency are of little practical value. What is of high value is pulse energy, high signal to noise ratio (expressed as pre-pulse contrast), good beam quality, consistent output parameters and timing. Our system focuses on maximizing these parameters sometimes at the expense of efficient operation or average power. Our prototype system consists of a mode-locked fiber laser, a compressed pulse fiber amplifier, a “pulse cleaner”, a chirped fiber Bragg grating, pulse selectors, a transport fiber system and a large flattened mode fiber amplifier. In our talk we will review the system in detail and present theoretical and experimental studies of critical components. We will also present experimental results from the integrated system.
Fusion of Computer and Communication (2014)

The fusion of computer and communication technology on one hand and the in-depth integration of information processing systems into the daily operation of highly developed economies and societies on the other hand lead to a fundamental paradigm shift in the design and operation of computer systems. We need a new system development methodology that supports change and is not focused on design toward a static, authoritative specification, or a outdated system design view. This chapter elaborates on this fundamental required paradigm shift in computer system design and operation. It starts with a brief retrospective view of the time when computation, storage, and communication were still separate activities and the interface between a static computer system and the outside world was relegated to humans. In Section 7.3 the system-of-systems concept is explained as a possible answer to the posed problem of design for change. The chapter concludes with a demonstration of this concept in the well-known example of an ATM application.
Augmented Reality Web Applications with Mobile Agents in the Internet of Things (2014)

Augmented reality (AR) is a promising technology for building applications in an Internet of Things (IoT) environment, utilized for visualizing information provided by IoT devices. In this paper, we enable Web-based mobile AR applications with mobile agents in a resource-oriented IoT system architecture. We present an adaptable mobile agent composition that contains the data representation logic and mappings between AR applications and system resources. Thus, mobile agents and AR application-specific data structures are exposed as global system resources. System resource linkages are considered between real-world objects and their virtual representations for mobile agent-based AR applications. The agent composition also complies with the REST principles for resource access and control system-wide. This allows dynamic runtime adaptation and addressing the device and resource heterogeneity, thus eliminating the need for application-specific communication protocols. Moreover, we utilize a Web-based mobile AR application framework, running completely in a Web browser, which facilitates straightforward AR application development. Lastly, a proof of concept mobile AR application is implemented, where a coffee maker with a visual tag is connected to a low-power resource-constrained wireless sensor network node as an IoT device. A mobile agent is injected into the IoT environment to expose the state changes of the coffee maker. Through the visual tag, AR applications are able to visualize the state changes of the coffee maker in their user interface.
Reserpine-induced alterations in the processing of proenkephalin in cultured chromaffin cells. Increased amidation. (1986)

We have used antisera directed towards eight different portions of the proenkephalin molecule to examine the processing rates and patterns of proenkephalin-derived peptides in chromaffin cell cultures in the presence and absence of reserpine. Reserpine treatment produced profound effects on the molecular weight profile of nearly all enkephalin-containing peptides. Increased production of low molecular weight immunoreactive [Met5]enkephalin, [Leu5]enkephalin, [Met5]enkephalin-Arg6-Gly7-Leu8, and [Met5]enkephalin-Arg6-Phe7 was observed in reserpine-treated cultures; immunoreactivity corresponding to several intermediate sized enkephalin-containing peptides such as Peptide B and the high molecular weight [Met5]enkephalin-Arg6-Gly7-Leu8 immunoreactive peptide was decreased. The production of two amidated opioid peptides, amidorphin and metorphamide, was greatly accelerated in the presence of reserpine. The increased levels of low molecular weight enkephalins could not be accounted for by assuming decreased basal release. These results indicate that reserpine treatment is able to increase the extent of post-translational processing of proenkephalin within chromaffin cells.
Fabrication of 4H-SiC Planar MESFETs on High-Purity Semi-Insulating Substrates (2007)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Optimal recursive state estimation with quantized measurements (2000)

A set of exact nonlinear filters is derived and analyzed. The filters perform recursive state estimation when only coarsely quantized output signals are available. A system with the dynamics given by n integrators, together with a uniform prior on the state vector, form the model assumptions. In the case with one integrator, properties of the quantizer allows the construction of an exact recursive algorithm for the updating of the probability density function (p.d.f.), using only the corners of a convex polygon defining the region where the p.d.f. is nonzero. It is also shown how to generalize the algorithm to handle multiple measurements quantized with vector quantizers.
Dynamic hardware/software partitioning: a first approach (2004)

Partitioning an application among software running on a microprocessor and hardware co-processors in on-chip configurable logic has been shown to improve performance and energy consumption in embedded systems. Meanwhile, dynamic software optimization methods have shown the usefulness and feasibility of runtime program optimization, but those optimizations do not achieve as much as partitioning. We introduce a first approach to dynamic hardware/software partitioning. We describe our system architecture and initial on-chip tools, including profiler, decompiler, synthesis, and placement and routing tools for a simplified configurable logic fabric, able to perform dynamic partitioning of real benchmarks. We show speedups averaging 2.6 for five benchmarks taken from Powerstone, NetBench, and our own benchmarks.

Anatomically accurate modeling and rendering of the human eye (2007)

Recovering anatomical features of organic materials is a challenging issue. The human eye, as an important part of the non verbal communication, needs to be accurately modeled and rendered to increase the realism of virtual characters. The recent improvements of the graphics hardware offer the opportunity of rendering complex organic materials, following correct anatomical properties. We propose a novel method that allows to recover the iris structure and scattering features from a single eye photograph. In this aim, we developed a method to unrefract iris photographs. We model the iris using the Subsurface Texture Mapping representation [François et al.] which allows to describe the relieves of the human iris. Finally, we introduce a refraction function for accurate real-time rendering of the eye, accounting for the refraction of the light at the corneal interface.
