Band gap and band offset of (GaIn)(PSb) lattice matched to InP (2005)

Metastable (GaxIn1−x)(PySb1−y) layers were grown on (001) InP substrates by gas source molecular beam epitaxy. Low-temperature photoluminescence spectroscopy was applied to these heterostructures and revealed spatially indirect band-to-band recombination of electrons localized in the InP with holes in the (GaxIn1−x)(PySb1−y). In addition, samples with layer thicknesses larger than 100nm showed direct PL across the band gap of (GaxIn1−x)(PySb1−y). Band-gap energies and band offset energies of (GaxIn1−x)(PySb1−y) relative to InP were derived from these PL data. A strong bowing parameter was observed.
Phase I Trial of 17-Allylamino-17-Demethoxygeldanamycin in Patients with Advanced Cancer (2007)

The MTD and toxicity profile of 17-AAG were schedule dependent. Intermittent dosing schedules were less toxic and are recommended for future phase II studies.
Compressible Elastohydrodynamic Lubrication of Rough Surfaces (1989)

A complete numerical solution of compressible elastohydrodynamic lubrication of rough surfaces has been obtained. The Newton-Raphson technique is used to solve the simultaneous system of modified compressible Reynolds and elasticity equations. The effects of various loads, surface pattern, and roughness parameter have been investigated. Results have been presented for loads ranging from W = 2.0452 × 10−5 to W = 2.3 × 10−4 at the speed of U = 1.0 × 10−11. The results indicate that the compression effects are significant and cannot be neglected.
Optimum partial interference canceling factor in pilot assistant coherent ofdm system with partial power training sequence synchronization (2004)

Correct time and frequency synchronization is important for the performance of orthogonal frequency-division multiplexing (OFDM) system. While using the partial power training sequences to synchronize in orthogonal frequency-division multiplexing (OFDM) system, the received data signals will be interfered by the training sequences. In this paper, we give a method for suppressing the interference caused by the training sequence, and introduce an optimized formula for the partial interference canceling factor of partial power training sequence. The above technique is evaluated by means of pilot assistant coherent OFDM system under time-varying multipath Rayleigh fading channels, and the linear interpolation channel estimator is employed to exploit the frequency domain correlation. Especially we focus on only one OFDM symbol in a packet transmission, that is, both the OFDM data and the training sequences are included in one OFDM symbol, and there are no other symbols before or after it. Both theoretical and simulated results of the above technique are presented. It has been shown that the better BER performance can be achieved as compared with no separation, and only the one OFDM symbol can accomplish user data communication assignment.
A personalized researcher recommendation approach in academic contexts: Combining social networks and semantic concepts analysis (2010)

The rapid proliferation of information technologies especially the web 2.0 techniques have changed the fundamental ways how things can be done in many areas, including how researchers could communicate and collaborate with each other. The presence of the sheer volume of researcher and topical research information on the Web has led to the problem of information overload. There is a pressing need to develop researcher recommender systems such that users can be provided with personalized recommendations of the researchers they can potentially collaborate with for mutual research benefits. In an academic context, recommending suitable research partners to researchers can facilitate knowledge discovery and exchange, and ultimately improve the research productivity of both sides. Existing expertise recommendation research usually investigates into the expert finding problem from two independent dimensions, namely, the social relations and the common expertise. The main contribution of this paper is that we propose a novel researcher recommendation approach which combines the two dimensions of social relations and common expertise in a unified framework to improve the effectiveness of personalized researcher recommendation. Moreover, how our proposed framework can be applied to the real-world academic contexts is explained based on two case studies.
Different molecular pathways determining extrahepatic and intrahepatic recurrences of hepatocellular carcinoma (2006)

Recent genome-wide screens have identified genes associated with the metastatic potential of hepatocellular carcinoma (HCC); however, there is little overlap between the identified genes, and interpretations of the results remain controversial. These inconsistencies may be related to differences in the sample populations, use of distinct microarray platforms and algorithms, and the complicated modes of HCC recurrence. We investigated the gene expression profiles of extrahepatic recurrence (EHR) and early intrahepatic recurrence (IHR), which are two representative modes of recurrence of HCC attributable to metastasis. We used DNA microarray analysis and identified 46 signature genes for EHR in 35 HCCs in a supervised learning manner. The obtained gene expression profile was compared with that for early IHR that was determined previously in the same manner. The 46 signature genes for EHR included many cell adhesion-related genes (ITGA6, SPP1, DNMBP, CD44 and POSTN), which all showed higher expression in HCC with EHR than in HCC without EHR. The 46 signature genes for early IHR included 10 immune response-related genes, which all showed lower expression in HCC with early IHR than in HCC without early IHR. The signature genes for EHR included only two immune response-related genes (P=0.013). These results suggest that alteration of the cell adhesion system plays a central role in EHR and that reduction of the immune response is a specific step in early IHR. These results indicate that the metastatic processes in EHR and early IHR involve different molecular pathways.

Chosen-prefix collisions for MD5 and applications (2012)

We present a novel, automated way to find differential paths for MD5. Its main application is in the construction of chosen-prefix collisions. We have shown how, at an approximate expected cost of 239 calls to the MD5 compression function, for any two chosen message prefixes P and P′, suffixes S and S′ can be constructed such that the concatenated values P║S and P′║S′ collide under MD5. The practical attack potential of this construction of chosenprefix collisions is of greater concern than the MD5-collisions that were published before. This is illustrated by a pair of MD5-based X.509 certificates one of which was signed by a commercial Certification Authority (CA) as a legitimate website certificate, while the other one is a certificate for a rogue CA that is entirely under our control (cf. http://www.win.tue.nl/hashclash/rogue-ca/). Other examples, such as MD5-colliding executables, are presented as well. More details can be found on http://www.win.tue.nl/hashclash/ChosenPrefixCollisions/.
Verruciform xanthoma in association with a vulval fibroepithelial polyp. (1997)

We report the clinical, light microscopic, immunohistochemical and ultrastructural features of a verruciform xanthoma that developed in association with a vulval fibroepithelial polyp. To our knowledge, this is the first time that this association has been reported. Immunohistochemical findings confirmed that the xanthoma cells were of a monocyte/macrophage lineage. In addition to typical histological characteristics, prominent vascular ectasias were detected in the deep dermis at the periphery of this lesion. The ectasias may play a part in pathogenesis.
Optimal Daltonization by Spectral Shift for Dichromatic Vision (2012)

This paper proposes a spectral-based image daltonization algorithm for the dichromats getting the best visibility against their color deficiencies. The proposed model extracts the visible and invisible spectra to dichromatic vsion based on the projection theory of spectral space to/from 2-D dichromatic cone space.. First, the fundamental spectra C* visible to the trichromats are captured from the conventional sRGB camera images by a pseudo-inverse projection.. Second, the fundamental spectra C*DIC visible to the dichromats are obtained by operating the extended matrix RDIC based on matrix-R theory. Thirdly, the lost spectra ΔCDIC are calculated as the difference between C* and C*DIC.The key point in this paper is to make use of the lost spectra for image daltonization revived again. Though the lost spectra ΔCDIC are invisible to dichromats if left alone, they are shifted into the visible spectral region and added to the the fundamental spectra C* of source image. As a result, the dichromatic image visibility is dramatically improved.The optimal spectral shift is determined to maximizing the spectral visibility for the dichromats and minimizing the visual gap from the normals. The proposed algorithm is designed to solve a contradictory demand to cope with both dichromats and normals.The paper shows how the model works well for image daltonization better than the existing popular color blind simulators.
Analysis of Radio Frequency Blackout for a Blunt-Body Capsule in Atmospheric Reentry Missions (2016)

A numerical analysis of electromagnetic waves around the atmospheric reentry demonstrator (ARD) of the European Space Agency (ESA) in an atmospheric reentry mission was conducted. During the ARD mission, which involves a 70% scaled-down configuration capsule of the Apollo command module, radio frequency blackout and strong plasma attenuation of radio waves in communications with data relay satellites and air planes were observed. The electromagnetic interference was caused by highly dense plasma derived from a strong shock wave generated in front of the capsule because of orbital speed during reentry. In this study, the physical properties of the plasma flow in the shock layer and wake region of the ESA ARD were obtained using a computational fluid dynamics technique. Then, electromagnetic waves were expressed using a frequency-dependent finite-difference time-domain method using the plasma properties. The analysis model was validated based on experimental flight data. A comparison of the measured and predicted results showed good agreement. The distribution of charged particles around the ESA ARD and the complicated behavior of electromagnetic waves, with attenuation and reflection, are clarified in detail. It is suggested that the analysis model could be an effective tool for investigating radio frequency blackout and plasma attenuation in radio wave communication.
Acdidophilic thermophilic archaebacteria: Potential application for metals recovery (1990)

The acidophilic thermophilic archaebacteria Sulfolobus and Acidianus have the potential for applid use in the recovery of metal values from ores through the process of baterial leaching. These microbes readily adapt to the conditions of low pH and high concentrations of metals required for bacterial leaching. In addition, these archaebacteria can exist at high temperatures which can occur during the oxidation of metal sulfides in bioleaching reactors. The acidophilic of copper and molybdenum from chalcopyrite and molybdenite minerals, respectively. The microbes can also enhance the recovery of gold by oxidation of pyrite which occludes gold preventing recovery by standard metallurgical procedures. The ability of this group of microbes to facilitate metals recovery is yet to be developed on a commercial scale.

Stabilization of the liquid crystal director in the patterned vertical alignment mode through formation of pretilt angle by reactive mesogen (2007)

In the patterned vertical alignment (PVA) cell in which multidomains are formed from the perfect vertical alignment through an oblique field only, the formation of disclinations between liquid crystal (LC) molecules is inevitable in the presence of an electric field, which lowers transmittance and the response time. In the proposed PVA device, the pretilt angle is formed in four different directions through the polymerization of an UV curable reactive mesogen monomer at the surface. In this way, the reorientation of LC responding to an electric field is well defined, and thus the device shows reduced threshold voltage and much improved response time in all gray scales.
Liquid‐Liquid Interfacial Transport of Nanoparticles (2007)

The study presents the transfer of nanoparticles from the aqueous phase to the second nonmiscible nonaqueous liquid phase. The transfer is based on the sedimentation of the dispersed particles through a liquid‐liquid interface. First, the colloidal aqueous dispersion is destabilised to flocculate the particles. The agglomeration is reversible and the flocs are large enough to sediment in a centrifugal field. The aqueous dispersion is laminated above the receiving organic liquid phase. When the particles start to penetrate into the liquid‐liquid interface, the particle surface is covered with the stabilising surfactant. The sorption of the surfactant onto the surface of the primary particles leads to the disintegration of the flocs. This phase transfer process allows for a very low surfactant concentration within the receiving organic liquid, which is important for further application, that is, synthesis for polymer‐nanocomposite materials. Furthermore, the phase transfer of the nanoparticles shows a high efficiency up to 100% yield. The particle size within the organosol corresponds to the primary particle size of the nanoparticles.

M<scp>OLECULAR</scp>B<scp>IOLOGY OF</scp>F<scp>RUIT</scp>M<scp>ATURATION AND</scp>R<scp>IPENING</scp> (2001)

The development and maturation of fruits has received considerable scientific scrutiny because of both the uniqueness of such processes to the biology of plants and the importance of fruit as a significant component of the human diet. Molecular and genetic analysis of fruit development, and especially ripening of fleshy fruits, has resulted in significant gains in knowledge over recent years. Great strides have been made in the areas of ethylene biosynthesis and response, cell wall metabolism, and environmental factors, such as light, that impact ripening. Discoveries made in Arabidopsis in terms of general mechanisms for signal transduction, in addition to specific mechanisms of carpel development, have assisted discovery in more traditional models such as tomato. This review attempts to coalesce recent findings in the areas of fruit development and ripening.
Asymmetric Radical Addition of TEMPO to Titanium Enolates (2013)

A mild method for α-hydroxylation of N-acyl oxazolidinones by asymmetric radical addition of the 2,2,6,6-tetramethylpiperidine N-oxy (TEMPO) radical to titanium enolates was developed. The high diastereoselectivity and broad scope of the reaction show synthetic utility for the α-hydroxylation of substrates that are not tolerant to strongly basic conditions.
Environmentally Friendly Surface Modification Treatment of Flax Fibers by Supercritical Carbon Dioxide (2020)

The present work investigates the effects of an environmentally friendly treatment based on supercritical carbon dioxide (scCO<sub>2</sub>) on the interfacial adhesion of flax fibers with thermoset matrices. In particular, the influence of this green treatment on the mechanical (by single yarn tensile test), thermal (by TGA), and chemical (by FT-IR) properties of commercially available flax yarns was preliminary addressed. Results showed that scCO<sub>2</sub> can significantly modify the biochemical composition of flax fibers, by selectively removing lignin and hemicellulose, without altering their thermal stability and, most importantly, their mechanical properties. Single yarn fragmentation test results highlighted an increased interfacial adhesion after scCO<sub>2</sub> treatment, especially for the vinylester matrix, in terms of reduced debonding and critical fragment length values compared to the untreated yarns by 18.9% and 15.1%, respectively. The treatment was less effective for epoxy matrix, for which debonding and critical fragment length values were reduced to a lesser extent, by 3.4% and 3.7%, respectively.

Improving performance of TCP over wireless networks (2002)

Transmission Control Protocol (TCP) assumes a relatively reliable underlying network where most packet losses are due to congestion. In a wireless network, however, packet losses will occur more often due to unreliable wireless links than due to congestion. When using TCP over wireless links, each packet loss on the wireless link results in congestion control measures being invoked at the source. This causes severe performance degradation. In this paper, we study the effect of: burst errors on wireless links; packet size variation on the wired network; local error recovery by the base station; and explicit feedback by the base station, on the performance of TCP over wireless networks. It is shown that the performance of TCP is sensitive to the packet size, and that significant performance improvements are obtained if a good packet size is used. While local recovery by the base station using link-level retransmissions is found to improve performance, timeouts can still occur at the source, causing redundant packet retransmissions. We propose an explicit feedback mechanism, to prevent these timeouts during local recovery. Results indicate significant performance improvements when explicit feedback from the base station is used. A major advantage of our approaches over existing proposals is that no state maintenance is required at any intermediate host. Experiments are performed using the Network Simulator (NS) from Lawrence Berkeley Labs. The simulator has been extended to incorporate wireless link characteristics.
Analyzing Multi-Objective Linear and Mixed Integer Programs by Lagrange Multipliers (1991)

A new method for multi-objective optimization of linear and mixed programs based on Lagrange multiplier methods is developed. The method resembles, but is distinct from, objective function weighting and goal programming methods. A subgradient optimization algorithm for selecting the multipliers is presented and analyzed. The method is illustrated by its application to a model for determining the weekly re-distribution of railroad cars from excess supply areas to excess demand areas, and to a model for balancing cost minimization against order completion requirements for a dynamic lot size model.
Fragment reconstruction: providing global cache coherence in a transactional storage system (2002)

Cooperative caching is a promising technique to avoid the increasingly formidable disk bottleneck problem in distributed storage systems; it reduces the number of disk accesses by servicing client cache misses from the caches of other clients. However, existing cooperative caching techniques do not provide adequate support for fine grained sharing. We describe a new storage system architecture, split caching, and a new cache coherence protocol, fragment reconstruction, that combine cooperative caching with efficient support for fine grained sharing and transactions. We also present the results of performance studies that show that our scheme introduces little overhead over the basic cooperative caching mechanism and provides better performance when there is fine grained sharing.
