An outline of the synthesis and properties of silicon nanowires (2010)

We consider some of the significant aspects of Silicon nanowires (NWs), referring to their various modes of fabrication and their measured properties. Lithographic patterning as well as individual NW synthesis, e.g., through chemical vapor deposition based processes, has been utilized for their fabrication. It is seen that the properties of these nanostructures, to a large extent, are determined by the enhanced surface area to volume ratio and defects play a relatively major role. A diminished size also brings forth the possibility of quantum confinement effects dictating their electronic and optical properties, e.g., where NWs can possess a direct energy gap in contrast to the indirect bandgap of bulk Si. While new challenges, such as enhanced Ohmic contact resistance, carrier depletion–which can severely influence electrical conduction, and surface passivation abound, there also seem to be exciting opportunities. These include, e.g., high sensitivity sensors, nanoelectromechanical systems, and reduced thermal conductivity materials for thermoelectrics. Much preliminary work has been done in these areas as well as investigating the possible use of Si NWs for transistor applications, photovoltaics, and electrochemical batteries etc., all of which are briefly reviewed.
Chimpanzee Reservoirs of Pandemic and Nonpandemic HIV-1 (2006)

Human immunodeficiency virus type 1 (HIV-1), the cause of human acquired immunodeficiency syndrome (AIDS), is a zoonotic infection of staggering proportions and social impact. Yet uncertainty persists regarding its natural reservoir. The virus most closely related to HIV-1 is a simian immunodeficiency virus (SIV) thus far identified only in captive members of the chimpanzee subspecies Pan troglodytes troglodytes. Here we report the detection of SIVcpz antibodies and nucleic acids in fecal samples from wild-living P. t. troglodytes apes in southern Cameroon, where prevalence rates in some communities reached 29 to 35%. By sequence analysis of endemic SIVcpz strains, we could trace the origins of pandemic (group M) and nonpandemic (group N) HIV-1 to distinct, geographically isolated chimpanzee communities. These findings establish P. t. troglodytes as a natural reservoir of HIV-1.
Design and Implementation of Cache Partitioning in Virtual Machine System (2010)

This paper presents a cache partitioning approach which can be implemented in the VMM(virtual machine manager).This approach has been implemented in Xen VMM using the page coloring technique traditionally applied to the OS(operating system).The VMM-based implementation is fully transparent to the guest OS.It thus shows the advantages of simplicity and flexibility.The evaluation shows that this cache partitioning method can work efficiently and improve the performance of co-scheduled applications running within different VMs.In the concurrent workloads selected from the SPEC CPU 2006 benchmarks,the technique achieves a performance improvement by up to 19% for the most sensitive workloads.
Sorption Behavior of Binary Gas CO<sub>2</sub>/CH<sub>4</sub> on Ordered Mesoporous Carbon with the Presence of Water (2016)

Utilizing dynamic adsorptive method, the static equilibrium sorption data of CO2/CH4 binary gases with four different concentrations on CMK-3 present with water were collected. Compared with similar system only in bulk water, it was found that the whole adsorptive process was considerably complex, which was mixed gas hydrate formation with competitive adsorption. The comprehensive discussions about equilibrium of binary gas on wet CMK-3 have been present here with generating reasonable conclusions. The CO2/CH4 selectivity was also calculated as the important support for CO2/CH4 separation by using gas hydrate formation in porous materials.
A set of defined oncogenic mutation alleles seems to better predict the response to cetuximab in CRC patient-derived xenograft than KRAS 12/13 mutations (2015)

Cetuximab is a standard of care for treating EGFR-expressing metastatic colorectal carcinoma (mCRC) exclusive of those with KRAS mutations at codons 12/13. However, retrospective analysis has recently suggested that KRAS-G13D patients can still benefit, while only a fraction of KRAS wild-type patients can benefit, from the treatment. We set out to test this contradicting issue experimentally in an independent cohort of patient derived xenograft (PDX) diseases. We conducted a mouse clinical trial (MCT) enrolling a random cohort of 27 transcriptome sequenced CRC-PDXs to evaluate cetuximab activity. The treatment responses were analyzed against the KRAS 12/13 mutation alleles, as well as several other well-known oncogenic alleles. If the response is defined by >80% tumor growth inhibition, 8/27 PDXs (~30%) are responders versus 19/27 non-/partial responders (~70%). We found that indeed there are no significantly fewer KRAS-12/13-allele responders (4/8 or 50%) than non-/partial responders (7/19, or 37%). In particular, there are actually no fewer G13D responders (4/8, or 50%) than in non-/partial responders (2/19 or 10.5%) statistically. Furthermore, majority of the non-/partial responders tend to have certain activating oncogenic alleles (one or more of the following common ones: K/N-RAS-G12V/D, -A146T, -Q61H/R, BRAF-V600E, AKT1-L52R and PIK3CA-E545G/K). Our data on an independent cohort support the recent clinical observation, but against the current practiced patient stratification in the cetuximab CRC treatment. Meanwhile, our data seem to suggest that a set of the six-oncogenic alleles may be of better predictive value than the current practiced stratification, justifying a new prospective clinical investigation on an independent cohort for confirmation.
MAGERI: Computational pipeline for molecular-barcoded targeted resequencing (2017)

Unique molecular identifiers (UMIs) show outstanding performance in targeted high-throughput resequencing, being the most promising approach for the accurate identification of rare variants in complex DNA samples. This approach has application in multiple areas, including cancer diagnostics, thus demanding dedicated software and algorithms. Here we introduce MAGERI, a computational pipeline that efficiently handles all caveats of UMI-based analysis to obtain high-fidelity mutation profiles and call ultra-rare variants. Using an extensive set of benchmark datasets including gold-standard biological samples with known variant frequencies, cell-free DNA from tumor patient blood samples and publicly available UMI-encoded datasets we demonstrate that our method is both robust and efficient in calling rare variants. The versatility of our software is supported by accurate results obtained for both tumor DNA and viral RNA samples in datasets prepared using three different UMI-based protocols.
Direct Synthesis of <i>N</i>-H Carbazoles via Iridium(III)-Catalyzed Intramolecular C–H Amination (2015)

The iridium-catalyzed dehydrogenative cyclization of 2-aminobiphenyls proceeds smoothly in the presence of a copper cocatalyst under air as a terminal oxidant through intramolecular direct C-H amination to produce N-H carbazoles. A similar iridium/copper system can also catalyze the unprecedented dimerization reaction of 2-aminobiphenyl involving 2-fold C-H/N-H couplings.
A high-speed analog min-sum iterative decoder (2005)

Current-mode circuits are presented for implementing analog min-sum (MS) iterative decoders. Proposed circuits are devised based on current mirrors. Therefore, in any fabrication technology that accurate current mirrors can be designed, analog MS decoders can be implemented. The functionality of the proposed modules was verified by implementing an analog MS decoder for a (32,8,10) regular LDPC code in 0.18-mum CMOS technology. In low signal to noise ratios when the circuit imperfections are dominated by the noise of the channel, the measured error correcting performance of this chip in steady-state condition surpasses that of the conventional MS decoder, and is close to the performance predicted by the earlier work on the dynamics of the continuous-time analog decoding by Hemati and Banihashemi, ISIT2004. At a throughput of 24 Mb/s, loss in the coding gain compared to the conventional MS decoder at BER of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> is about 0.3 dB. To the best of our knowledge, this decoder has the highest throughput and the lowest power/speed ratio among the reported analog CMOS iterative decoders
Flame Retardancy of High-Density Polyethylene Composites with P,N-Doped Cellulose Fibrils (2020)

To derive P,N-doped cellulose fibrils, phosphoric acid and aqueous ammonia were placed in a one-pot reaction, and the phosphate groups and ammonium phosphates were successfully introduced into the cellulose surface. The obtained P,N-doped cellulose fibrils with high liberation were thereafter incorporated into a high-density polyethylene (HDPE) matrix to improve the flame retardancy of HDPE composites, and they had a significant improvement on flame retardancy of HDPE composites. In particular, 7 wt % P,N-doped cellulose fibrils considerably reduced the average and peak heat release rate (HRR) by 29.6% and 72.9%, respectively, and increased the limited oxygen index (LOI) by 30.5%. The presence of phosphate groups and ammonium phosphates within P,N-doped cellulose fibrils was found to promote the thermal degradation of HDPE composites at a lower temperature (i.e., 240 °C). The released acid catalyzed the dehydration of cellulose to form an aromatic carbonaceous structure with a higher crystalline orientation, which improves the flame retardancy of HDPE composites.
Dynamic software update for component-based distributed systems (2011)

Dynamic evolution is a key aspect of the design, development, and maintenance of complex and distributed software systems built by integrating components. Evolution, tradi- tionally obtained by producing software upgrades, may de- rive from changes in the requirements or in the environment, from the need to incorporate new implemented versions and optimizations. Upgrades typically require the software sys- tem to be shutdown, updated and restarted. However a large number of applications require to offer a continuous service. The goal of this research is to support online software re- configuration without service interruption by analyzing the conditions of substitutability of components and their inter- actions and by producing automatic methods for dynamic update.
Predicting Future Frames Using Retrospective Cycle GAN (2019)

Recent advances in deep learning have significantly improved the performance of video prediction, however, top-performing algorithms start to generate blurry predictions as they attempt to predict farther future frames. In this paper, we propose a unified generative adversarial network for predicting accurate and temporally consistent future frames over time, even in a challenging environment. The key idea is to train a single generator that can predict both future and past frames while enforcing the consistency of bi-directional prediction using the retrospective cycle constraints. Moreover, we employ two discriminators not only to identify fake frames but also to distinguish fake contained image sequences from the real sequence. The latter discriminator, the sequence discriminator, plays a crucial role in predicting temporally consistent future frames. We experimentally verify the proposed framework using various real-world videos captured by car-mounted cameras, surveillance cameras, and arbitrary devices with state-of-the-art methods.
An approach to the diagonalization of the discrete Fourier transform (2005)

We study the problem of diagonalizing the DFT by finding eigenvectors through the use of commuting operators. An explicit form for the polar representation of the DFT is presented and powers of the DFT are studied. Possible applications to signal multiplexing and transform coding are suggested.

Polyethylenimine‐Grafted Multiwalled Carbon Nanotubes for Secure Noncovalent Immobilization and Efficient Delivery of DNA (2005)

DNA hits the wall: DNA is immobilized securely onto the surface of multiwalled carbon nanotubes through electrostatic interactions with grafted polyethylenimine (PEI; see picture). The polyethylenimine-graft multiwalled carbon nanotubes carrying DNA show transfection efficiency for DNA delivery similar to or even several times higher than PEI.

CHANGES IN ISOPEROXIDASE PATTERNS DURING THE IN VITRO ROOTING OF NOTHOFAGUS ANTARCTICA (2001)

Summary. Peroxidases play a major role in several physiological processes. Specifically, in vitro activity of this enzyme was used as a marker to identify different rooting phases of Nothofagus. The study of peroxidase profile patterns during rhizogenesis in this genus could give additional information about this topic, to justify the use of peroxidase isoforms as a more specific biochemical marker than total peroxidase activity. This work gives information on qualitative and quantitative changes in isoperoxidase expression (basic and acidic peroxidases) during in vitro rooting of N. antarctica microshoots through native PAGE. Time course analysis of isoperoxidase activity during rhizogenesis allowed positive correlation with specific morphogenic stages. Seventeen peroxidase bands were detected, 4 basic and 13 acidic. Four of the acidic peroxidases appeared during the induction stage of rooting. Variation in the number and relative activity of the isoperoxidases was found during different stages of adventitious rooting. The variation in the number and activity of isoperoxidases provides a good indicator of the processes involved in adventitious rooting of N. antarctica. Possible linkage of basic isoperoxidases with auxin metabolism and the role of certain isoperoxidases in specific rooting processes are also discussed.
Very large bandwidth IF SAW filters using leaky waves on LiNbO<inf>3</inf> and LiTaO<inf>3</inf> (2011)

It was previously reported that a leaky wave propagating on 41°Y-X LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> and 36°Y-X LiTaO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> substrates, has a relatively low temperature coefficient of frequency (TCF) and a large electromechanical coupling factor (K <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ). In this study, we investigated the performance of wide band IF SAW filters using a FAN - shaped structure and leaky wave mode.

Mechanistic Investigation of Water Oxidation Catalyzed by Uniform, Assembled MnO Nanoparticles (2016)

The development of active water oxidation catalysts is critical to achieve high efficiency in overall water splitting. Recently, sub-10 nm-sized monodispersed partially oxidized manganese oxide nanoparticles were shown to exhibit not only superior catalytic performance for oxygen evolution, but also unique electrokinetics, as compared to their bulk counterparts. In the present work, the water-oxidizing mechanism of partially oxidized MnO nanoparticles was investigated using integrated in situ spectroscopic and electrokinetic analyses. We successfully demonstrated that, in contrast to previously reported manganese (Mn)-based catalysts, Mn(III) species are stably generated on the surface of MnO nanoparticles via a proton-coupled electron transfer pathway. Furthermore, we confirmed as to MnO nanoparticles that the one-electron oxidation step from Mn(II) to Mn(III) is no longer the rate-determining step for water oxidation and that Mn(IV)═O species are generated as reaction intermediates during catalysis.
Big Graph Analyses: From Queries to Dependencies and Association Rules (2017)

This position paper provides an overview of our recent advances in the study of big graphs, from theory to systems to applications. We introduce a theory of bounded evaluability, to query big graphs by accessing a bounded amount of the data. Based on this, we propose a framework to query big graphs with constrained resources. Beyond queries, we propose functional dependencies for graphs, to detect inconsistencies in knowledge bases and catch spams in social networks. As an example application of big graph analyses, we extend association rules from itemsets to graphs for social media marketing. We also identify open problems in connection with querying, cleaning and mining big graphs.
Exercise duration and thermoregulatory responses after whole body precooling (1995)

Whole body precooling was hypothesized to reduce thermoregulatory and metabolic responses, thereby enhancing running time. Fourteen male runners completed two high-intensity running tests consisting of resting in 24 degrees C (normothermic condition; NC) or 5 degrees C (hypothermic condition; HC) for 30 min followed by 10-16 min of rest at 24 degrees C and then an exercise bout (24 degrees C) at 82% maximal aerobic capacity to exhaustion. Rectal temperature (Tre) before exercise was lower (by 0.37 degrees C; P < 0.005) and exercise duration was longer (by 121 +/- 24%; P < 0.05) in HC than in NC. Tre and mean skin (Tsk) and mean body (Tb) temperatures remained lower during HC (P < 0.01). Pre- and postexercise changes for Tsk, Tb, thermal gradient (Tre-Tsk), and heart rate (HR) were larger in HC than in NC (P < 0.05). Final Tre, Tre-Tsk, HR, and blood lactate were similar between HC and NC. During exercise, heat storage was greater (P < 0.01) in HC than in NC (173 +/- 46 and 143 +/- 38 W/m2, respectively) and subjects sweated more in NC than in HC (P < 0.01). O2 consumption was lower initially in HC than in NC (P < 0.05), but O2 pulse was not different. It was concluded that precooling results in greater exercise endurance with enhanced heat storage rate and less stress on metabolic and cardiovascular systems.
A four point-probe cell for resistivity measurement at high temperature (1975)

A four point-probe cell for measuring electrical resistivity of semiconducting compounds, particularly oxides at high temperature has been fabricated based on the theories of Uhlir (1955) and Smits (1958). Platinum-40% rhodium pins mounted on a stabilized zirconia block serve as the probe assembly. Using the cell for DC measurements, resistivities from 0.1-106 Omega cm can be conveniently measured against temperature with an accuracy of 3-0.5% depending on the order of magnitude of the resistivity to be measured. The data obtained are found to be highly reproducible.
Expression of atrial natriuretic factor as a cleavable fusion protein with chloramphenicol acetyltransferase in <i>Escherichia coli</i> (1988)

Recombinant fusion proteins containing human atrial natriuretic factor, ANF(1-28) joined to chloramphenicol acetyltransferase (CAT) via cleavable linker sequences have been produced in Escherichia coli. The linker sequences were designed to allow the release of authentic ANF(1-28) following proteolytic cleavage by enterokinase or thrombin, or chemical cleavage with 2-(2-nitrophenylsulphenyl)-3-methyl-3'-bromoindolenine. Proteins, containing ANF(1-28) fused to the carboxyl-terminal region of CAT (using the ScaI restriction site in the cat gene), were largely soluble in E. coli and were obtained in higher yield than analogues containing ANF(1-28) linked to shorter CAT sequences. The longer derivatives also retained CAT activity allowing subsequent purification by affinity chromatography.

Economic Crimes in the People's Republic of China: A Swinging Door Policy (1989)

New systemic features have emerged since the open-door policy.For example, central administrative control, as practiced during the Maoist period,' began to weaken markedly in the mid-1980s.7This led to a greater fragmentation of central power as the Communist party of China (Party) began to relinquish part of its control to local governments."The resultant increase in local autonomy created more opportumost significant sector in the national economy); see also THE PEOPLE'S REPUBLIC OF
