Chiral liquid crystal dopants derived from optically active drugs (2009)

In this article we examine the possibility of using chiral pharmaceuticals as reactive substrates in the synthesis of chiral liquid crystals because chiral drugs usually have reproducibly high chemical and optical purities which are important for applications of chiral liquid crystals. Thus we combined racemic and S-ibuprofen, racemic and S-ketoprofen and S-naproxen with a fluoroterphenyl promesogenic material in order to create bent core materials which we predicted would have helical twisting powers depending on the extent of the molecular bending.
Insulin receptor overexpression in 184B5 human mammary epithelial cells induces a ligand‐dependent transformed phenotype (1995)

To determine the role of the insulin receptor overexpression in breast epithelial cell transformation, the 184B5 human breast epithelial cell line was transfected with human insulin receptor cDNA. In two cell lines transfected with and overexpressing human insulin receptors (IR) (223.8 and 184.5 ng IR/10(6) cells), but not in untransfected cells, insulin binding and tyrosine kinase activity were elevated, and insulin induced a dose-dependent increase in colony formation in soft agar.

Kinetics of J-Aggregate Formation on the Surface of Au Nanoparticle Colloids (2012)

The kinetics of J-aggregate assembly on the surface of noble metal nanoparticle colloids are described, providing new mechanistic insight into the interaction of the dye molecules with the surface of metal nanoparticles. We specifically studied the J-aggregation of a thiacyanine dye (TC, 3,3′-disulfopropyl-5,5′-dichlorothiacyanine sodium salt) on the surface of gold nanoparticle colloids. The hybrid J-aggregate–Au colloidal dispersions were characterized by UV–vis spectrophotometry, fluorescence measurements, zeta potential measurements, and TEM analysis. Kinetic measurements were carried out using a stopped-flow method, indicating that the J-aggregate formation on the surface occurs via a two-step process. The first step includes adsorption of the initial dye layer, followed by an order of magnitude slower growth of consecutive layers. Activation parameters determined from the fluorescence measurements yielded further details about the nature of the interaction.
PQTable: Nonexhaustive Fast Search for Product-Quantized Codes Using Hash Tables (2017)

In this paper, we propose a product quantization table (PQTable)-a fast search method for product-quantized codes via hash tables. An identifier of each database vector is associated with the slot of a hash table by using its PQ-code as a key. For querying, an input vector is PQ-encoded and hashed, and the items associated with that code are then retrieved. The proposed PQTable produces the same results as a linear PQ scan, and is 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> -10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sup> times faster. Although the state-of-the-art performance can be achieved by previous inverted-indexing-based approaches, such methods require manually designed parameter setting and significant training; our PQTable is free of these limitations, and therefore offers a practical and effective solution for real-world problems. Specifically, when the vectors are highly compressed, our PQTable achieves one of the fastest search performances on a single CPU to date with significantly efficient memory usage (0.059-ms per query over 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sup> data points with just 5.5-GB memory consumption). Finally, we show that our proposed PQTable can naturally handle the codes of an optimized product quantization (OPQTable).
Nucleotide sequences and heterologous expression of tcmG and tcmP, biosynthetic genes for tetracenomycin C in Streptomyces glaucescens (1993)

The nucleotide sequence of the tcmIII, tcmIc, and tcmVII region of the tetracenomycin (TCM) C gene cluster of Streptomyces glaucescens ETH 22794 (GLA.0) revealed the presence of two genes, tcmP and tcmG. The deduced product of tcmG resembles flavoprotein hydroxylases found in several other bacteria, whereas the predicted amino acid sequence of tcmP is not significantly similar to those of any known proteins in the available data bases. Southern blot hybridization revealed an approximately 180-bp deletion in a tcmIII (tcmG) mutant and a 1,800-bp insertion in a tcmVII (tcmP) mutant. Heterologous expression of tcmG and tcmP in Streptomyces lividans and tcmP in Escherichia coli established that tcmP encodes an O-methyltransferase, catalyzing the methylation of the C-9 carboxy group of TCM E to yield TCM A2, and that tcmG is responsible for the hydroxylation of TCM A2 at positions C-4, C-4a, and C-12a to give TCM C. These are the final two steps of TCM C biosynthesis.

Transport Spectroscopy of Single Phosphorus Donors in a Silicon\n Nanoscale Transistor (2009)

We have developed nano-scale double-gated field-effect-transistors for the\nstudy of electron states and transport properties of single\ndeliberately-implanted phosphorus donors. The devices provide a high-level of\ncontrol of key parameters required for potential applications in\nnanoelectronics. For the donors, we resolve transitions corresponding to two\ncharge states successively occupied by spin down and spin up electrons. The\ncharging energies and the Lande g-factors are consistent with expectations for\ndonors in gated nanostructures.\n
A radially controlled ZnS interlayer on ultra-long ZnO–Gd2S3 core–shell nanorod arrays for promoting the visible photocatalytic degradation of antibiotics (2020)

Nanorod (NR) arrays offer commendable visible-light-driven photocatalytic performances. Herein, we describe the construction of a ternary ZnO-ZnS-Gd<sub>2</sub>S<sub>3</sub> nanostructural array in which a sulfidation process is used to decorate a Gd<sub>2</sub>S<sub>3</sub> shell layer with a ZnS interface over vapor-phase-grown vertically-aligned ZnO. With control over the shell-wall thickness, the shell layer of ∼25 nm wall thickness on the ultra-long ZnO NR arrays exhibited a higher catalytic efficiency close to 3.3, 2.0, 1.2, and 1.8 times those of the bare ZnO, the ZnO-ZnS, the Gd<sub>2</sub>S<sub>3</sub>-decorated (∼10 nm) and Gd<sub>2</sub>S<sub>3</sub> shell-layered (∼40 nm) ZnO-ZnS core-shell structures, respectively. The core-shell geometry and the shell-wall thickness with maximized contact interface afforded increased light absorption in the visible region and effectively retarded the recombination rate of the photoinduced charge carriers by confining electrons and holes separately, thus providing advantages in terms of the degradation of the pharmaceutical residue tetracycline and the industrial pollutant 4-nitrophenol in wastewater.
Linking energy policy, electricity generation and transmission using strong sustainability and co-optimization (2009)

The design of a sustainable electricity generation and transmission system is based on the established science of anthropogenic climate change and the realization that depending on imported fossil-fuels is becoming a measure of energy insecurity of supply. A model is proposed which integrates generation fuel mix composition, assignment of plants and optimized power flow, using Portugal as a case study. The result of this co-optimized approach is an overall set of generator types/fuels which increases the diversity of Portuguese electricity supply, lowers its dependency on imported fuels by 14.62% and moves the country towards meeting its regional and international obligations of 31% energy from renewables by 2020 and a 27% reduction in greenhouse gas emissions by 2012, respectively. The quantity and composition of power generation at each bus is specified, with particular focus on quantifying the amount of distributed generation. Based on other works, the resultant, overall distributed capacity penetration of 19.02% of total installed generation is expected to yield positive network benefits. Thus, the model demonstrates that national energy policy and technical deployment can be linked through sustainability and, moreover, that the respective goals may be mutually achieved via holistic, integrated design.
Exact tree-based FPGA technology mapping for logic blocks with independent LUTs (1998)

The logic blocks (CLBs) of a lookup table (LUT) based FPGA consist of one or more LUTs, possibly of different sizes. In this paper, we focus on technology mapping for CLBs with several independent LUTs of two different sizes (called ICLBs). The Actel ES6500 family is an example of a class of commercially available ICLBs. Given a tree network with n nodes, the only previously known approach for minimum area tree-based mapping to ICLBs was a heuristic with running time Θ(nd+1, where d is the maximum indegree of any node. We give an O(n3) time exact algorithm for mapping a given tree network, an improvement over this heuristic in terms of run time and the solution quality. For general networks, an effective strategy is to break it into trees and combine them. We also give an O(n3) exact algorithm for combining the optimal solutions to these trees, under the condition that LUTs do not go across trees. The method can be extended to solve mapping onto CLBs that can be configured into different ICLBs, (e.g. Xilinx' XC4000E).

Room-Temperature Quantum Emitter in Aluminum Nitride (2020)

A device that is able to produce single photons is a fundamental building block for a number of quantum technologies. Significant progress has been made in engineering quantum emission in the solid state, for instance, using semiconductor quantum dots as well as defect sites in bulk and two-dimensional materials. Here we report the discovery of a room-temperature quantum emitter embedded deep within the band gap of aluminum nitride. Using spectral, polarization, and photon-counting time-resolved measurements we demonstrate bright (>10<sup>5</sup> counts s<sup>-1</sup>), pure (<i>g</i> <sup>(2)</sup>(0) < 0.2), and polarized room-temperature quantum light emission from color centers in this commercially important semiconductor.

A Scalable Multiplier for Arbitrary Large Numbers Supporting Homomorphic Encryption (2013)

With the advent of cloud computing, encrypting remote program execution becomes plausible. Homomorphic encryption scheme is a potentially promising to realize that. However, it is not practically utilized due to its extremely slow execution speed. The scheme generally requires manipulating arbitrary large operand sizes, reaching out to billions of bits. This paper focuses on multiplication, as it is a fundamental operation in homomorphic encryption scheme. The scalability design aspect of multiplication is much more emphasized than in existing multiplier designs, in particular, transferring operands from memory can potentially be a limiting factor. Moreover, the area and speed of the multiplier core has to scale proportionally with the operand sizes. Additionally, the design has to efficiently handle variably sized operands, keeping hardware utilization as high as possible. In this paper, we propose a new regular multiplier design, based on the well-known serial/parallel design that allows for such requirements. It integrates pipelining and parallel operand partitioning to streamline memory transfers. The base design is verified by constructing a VHDL model, and evaluated analytically. The proposed accelerator architecture achieves linear time and cost complexities, and then can realize the linear scalability sought for homomorphic encryption applicability.
Multi-task Deep Neural Network for Joint Face Recognition and Facial Attribute Prediction (2017)

Deep neural networks have significantly improved the performance of face recognition and facial attribute prediction, which however are still very challenging on the million scale dataset, i.e. MegaFace. In this paper, we for the first time, advocate a multi-task deep neural network for jointly learning face recognition and facial attribute prediction tasks. Extensive experimental evaluation clearly demonstrates the effectiveness of our architecture. Remarkably, on the largest face recognition benchmark -- MegaFace dataset, our networks can achieve the Rank-1 identication accuracy of 77.74% and face verication accuracy 79.24% TAR at 10-6 FAR, which are the best performance on the small protocol among all the publicly released methods.
Defining Particle Size Distribution of Milled Biomass: Sieve Diameter versus Surface Area (2023)

<b><sc>Abstract.</sc></b> Sieving is the most used method to measure particle size distribution (PSD) of bulk solids, which is represented with a range of sieve hole diameters. The bioenergy community has used the sieve measurement for characterizing the PSD of milled biomass particles for years, due to its widely available apparatus and well-established operational standards. However, it is also well known that milled biomass particles (e.g., from corn stover) exhibit large aspect ratios in particle shapes (e.g., particle length can be 5-20 times of particle width or breadth). The resultant sieve diameters of those particles are usually not related to their true sizes. It has caused difficulties to properly establish functional relations between PSD and flowability for material handling equipment design, or between PSD and thermochemical properties for conversion process design, as two different groups of the same type of biomass (e.g., corn stover) that perform differently in material handling or thermochemical conversion may result in similar PSD using sieving. This work investigates possible relations and/or discrepancies between the sieve-based PSD and particle surface area-based PSD of knife mill size-reduced corn stalks. Confocal microscopy is used to measure the surface dimensions of milled corn stalk particles, as their breadth (i.e., the stalk skin thickness) is considered a value with relatively small variance from the same breed. Analysis is provided on whether sieve-based PSD exhibits a consistent relation to surface area-based PSD over different impeller rotational speeds. Thoughts are shared on the need for re-definition of PSD for milled corn stover particles. In addition, discrete element method (DEM) simulations of knife milling are conducted to predict the output size of milled corn stalks. Our results show that the DEM results achieve better agreement with the experimental data when using the particle surface-area based PSD.
Defining the critical hurdles in cancer immunotherapy (2011)

Scientific discoveries that provide strong evidence of antitumor effects in preclinical models often encounter significant delays before being tested in patients with cancer. While some of these delays have a scientific basis, others do not. We need to do better. Innovative strategies need to move into early stage clinical trials as quickly as it is safe, and if successful, these therapies should efficiently obtain regulatory approval and widespread clinical application. In late 2009 and 2010 the Society for Immunotherapy of Cancer (SITC), convened an "Immunotherapy Summit" with representatives from immunotherapy organizations representing Europe, Japan, China and North America to discuss collaborations to improve development and delivery of cancer immunotherapy. One of the concepts raised by SITC and defined as critical by all parties was the need to identify hurdles that impede effective translation of cancer immunotherapy. With consensus on these hurdles, international working groups could be developed to make recommendations vetted by the participating organizations. These recommendations could then be considered by regulatory bodies, governmental and private funding agencies, pharmaceutical companies and academic institutions to facilitate changes necessary to accelerate clinical translation of novel immune-based cancer therapies. The critical hurdles identified by representatives of the collaborating organizations, now organized as the World Immunotherapy Council, are presented and discussed in this report. Some of the identified hurdles impede all investigators; others hinder investigators only in certain regions or institutions or are more relevant to specific types of immunotherapy or first-in-humans studies. Each of these hurdles can significantly delay clinical translation of promising advances in immunotherapy yet if overcome, have the potential to improve outcomes of patients with cancer.
Sustained Off-Resonance Irradiation (SORI) (2016)

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy’s Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.
EXPERIMENTAL FACILITY FOR MEASURING THE IMPACT OF ENVIRONMENTAL NOISE AND SPEAKER VARIATION ON SPEECH-TO-SPEECH TRANSLATION DEVICES (2006)

We describe the construction and use of a laboratory facility for testing the performance of speech-to-speech translation devices. Approximately 1500 English phrases from various military domains were recorded as spoken by each of 30 male and 12 female English speakers with variation in speaker accent, for a total of approximately 60,000 phrases available for experimentation. We describe an initial experiment using the facility which shows the impact of environmental noise and speaker variability on phrase recognition accuracy for two commercially available one-way speech-to-speech translation devices configured for English-to-Arabic.
