Dielectric and dielectrophoretic properties of DNA (2009)

The physical properties of DNA are quite important for molecular genetics as well as for its nanotechnological applications. Studying the interactions of alternating current (AC) electric fields with deoxyribonucleic acid (DNA) allows one to draw conclusions about these properties. These interactions are usually investigated in two different ways. In dielectric spectroscopy, a DNA solution is placed in a homogeneous AC field and electronic parameters are measured over several frequency decades in the Hz to GHz range. These electronic data are then interpreted on the basis of physico-chemical models as a result of certain phenomena on the molecular level. In dielectrophoretic studies, a DNA solution is exposed to an inhomogeneous AC field and the spatial response of few or single molecules is monitored by optical or scanning force microscopy. This response can involve translation, elongation and orientation of the molecular strings. In this review, a survey is given of the literature dealing with the dielectric and dielectrophoretic properties of DNA as well as with applications of DNA dielectrophoresis.
Allelopathic effects of juglone and walnut leaf extracts on growth, fruit yield and plant tissue composition in strawberry cvs. ‘Camarosa’ and ‘Sweet Charlie’ (2005)

SummaryWe conducted an experiment in a heated greenhouse to investigate the effects of juglone (5-hydroxy-1,4-naphthoquinone) and walnut (Juglans regia L.) leaf extracts on yield, growth, chemical and plant nutrient element composition of short-day strawberry cultivars ‘Camarosa’ and ‘Sweet Charlie’. Strawberry plants were treated with 1 mM juglone or walnut leaf extracts (undiluted, or diluted 1:2, 1:4, 1:8). Vegetative and generative plant growth was inhibited strongly by treatment with both juglone and undiluted walnut leaf extracts. Fruit yield per plant, numbers of fruit per plant, average fruit weight, crowns per plant, numbers of leaves, leaf area, fresh root weight, total soluble solids, vitamin C, and acidity were all lower for juglone-treated plants compared to controls. All nutrient elements analysed in leaves were generally lower than in controls for all treatments except 1:8 diluted walnut extract. Results from this study should address concerns about growth inhibition of strawberry plants under walnut-based intercropping systems.
Multiple FM window antenna system for scanning diversity with an integrated processor (2002)

Modern active AM/FM window antennas and FM-antenna-diversity systems used for cars are described, and a novel type of window antenna is presented. For the antenna diversity system two main problems had to be solved. First, an extremely fast working criterion for FM distortions (noise, multipath distortion, equal channel, adjacent channel, and intermodulation distortion) had to be found. The time required for distortion detection in the realized system is only 25 mu s. In consequence, no audible distortion occurs before the next antenna is switched on. Second, multiantenna systems adequate for modern cars had to be developed. For increased FM performance quality multiantenna diversity systems are used. One of the systems has been implemented in a production by Philips, Fuba, and BMW. It consists of a diversity processor and three narrow-spaced active window antenna arranged in the rear window of BMW type seven and type five cars.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of Dynamic UbR-Proteasome Subcomplexes by In vivo Cross-linking (X) Assisted Bimolecular Tandem Affinity Purification (XBAP) and Label-free Quantitation (2016)

Proteasomes are protein degradation machines that exist in cells as heterogeneous and dynamic populations. A group of proteins function as ubiquitin receptors (UbRs) that can recognize and deliver ubiquitinated substrates to proteasome complexes for degradation. Defining composition of proteasome complexes engaged with UbRs is critical to understand proteasome function. However, because of the dynamic nature of UbR interactions with the proteasome, it remains technically challenging to capture and isolate UbR-proteasome subcomplexes using conventional purification strategies. As a result, distinguishing the molecular differences among these subcomplexes remains elusive. We have developed a novel affinity purification strategy, in vivo cross-linking (X) assisted bimolecular tandem affinity purification strategy (XBAP), to effectively isolate dynamic UbR-proteasome subcomplexes and define their subunit compositions using label-free quantitative mass spectrometry. In this work, we have analyzed seven distinctive UbR-proteasome complexes and found that all of them contain the same type of the 26S holocomplex. However, selected UbRs interact with a group of proteasome interacting proteins that may link each UbR to specific cellular pathways. The compositional similarities and differences among the seven UbR-proteasome subcomplexes have provided new insights on functional entities of proteasomal degradation machineries. The strategy described here represents a general and useful proteomic tool for isolating and studying dynamic and heterogeneous protein subcomplexes in cells that have not been fully characterized.

Cosmopolitanisms between the Americas (2005)

For almost a week in November 2002, Diamela Eltit was in the "house"—in the Casa de las Americas, the Cuban Revolution's beacon to cultures resistant to U.S. domination within the Americas. Along with other artists, Eltit founded the CADA (Colectivo de Acciones de Arte—Art Actions Collective) in Santiago, Chile in 1979. However, she gained international attention, primarily from academics in the United States, only after the publication of her first novel, Lumpérica, in 1983. The Casa de las Américas is located near Havana's Malecón, far from the scenarios of the Chilean neo-avant-garde where Eltit debuted. It announces itself as "a meeting place of all cultures of the Americas," and it has indeed successfully linked elements of cultures not only throughout Latin America but also with the other parts of the world. It has gone a long way toward fulfilling what it set out to do in 1959 under the direction of Haydee Santamaría, not only to help make Havana the principal meeting place for Latin American writers and artists, but also to be a repository and showcase for their works.
The rheological behavior of the skin: experimental results and a structural model1 (1979)

An all-optical long-distance multi-Gbytes/s bit-parallel WDM single-fiber link (1998)

An all-optical long-distance (>30 km) bit-parallel wavelength division multiplexed (WDM) single-fiber link with 12 bit-parallel channels having 1 Gbyte/s capacity has been designed. That system functionally resembles an optical fiber ribbon cable, except that all the bits pass on one fiber-optic waveguide. This single-fiber bit parallel wavelength link can be used to extend the (speed x distance) product of emerging cluster computer networks, such as, the MyriNet, SCI, Hippi-6400, ShuffleNet, etc. Here, the detailed design of this link using the commercially available Corning DS (dispersion-shifted) fiber is given. To demonstrate the viability of this link, two WDM channels at wavelengths 1530 and 1545 nm carrying 1 ns pulses on each channel were sent through a single 25.2-km long Corning DS fiber. The walkoff was 200 ps, well within the allowable setup and hold time for the standard ECL logic which is 350 ps for a bit period of 1 ns. This result implies that 30 bit-parallel beams spaced 1 nm apart between 1530-1560 nm, each carrying 1 Gbits/s signal, can be sent through a 25.2-km Corning DS fiber carrying information at a 30 Gb/s rate.

Results of the 2020 fastMRI Challenge for Machine Learning MR Image Reconstruction (2020)

Accelerating MRI scans is one of the principal outstanding problems in the MRI research community. Towards this goal, we hosted the second fastMRI competition targeted towards reconstructing MR images with subsampled k-space data. We provided participants with data from 7,299 clinical brain scans (de-identified via a HIPAA-compliant procedure by NYU Langone Health), holding back the fully-sampled data from 894 of these scans for challenge evaluation purposes. In contrast to the 2019 challenge, we focused our radiologist evaluations on pathological assessment in brain images. We also debuted a new Transfer track that required participants to submit models evaluated on MRI scanners from outside the training set. We received 19 submissions from eight different groups. Results showed one team scoring best in both SSIM scores and qualitative radiologist evaluations. We also performed analysis on alternative metrics to mitigate the effects of background noise and collected feedback from the participants to inform future challenges. Lastly, we identify common failure modes across the submissions, highlighting areas of need for future research in the MRI reconstruction community.
A I0-bit, 100 MS/s CMOS A/D Converter (2002)

Computational design of high-performance ligand for enantioselective Markovnikov hydroboration of aliphatic terminal alkenes (2018)

Finding optimal chiral ligands for transition-metal-catalyzed asymmetric reactions using trial-and-error methods is often time-consuming and costly, even if the details of the reaction mechanism are already known. Although modern computational analyses allow the prediction of the stereoselectivity, there are only very few examples for the attempted design of chiral ligands using a computational approach for the improvement of the stereoselectivity. Herein, we report a systematic method for the design of chiral ligands for the enantioselective Markovnikov hydroboration of aliphatic terminal alkenes based on a computational and experimental evaluation sequence. We developed a three-hindered-quadrant P-chirogenic bisphosphine ligand that was designed in accordance with the design guidelines derived from this method, which allowed the Markovnikov hydroboration to proceed with high enantioselectivity (up to 99% ee).
New high-speed induction motor driven by a commercial source (1987)

This paper described the structure and characteristics of a new high-speed induction motor. The motor has the magnetic combination of an induction motor and a magnetic frequency tripler and is called a "hybrid motor". When the three-phase to two-phase type tripler we proposed is adopted, this rotating-field type hybrid motor can be constructed. The motor has remarkable starting torque and operates near synchronous speed (10800rpm) by only an application of a 60 Hz commercial source. It is noted that the motor has no semiconductor device and a brushless structure.
Adaptations of block layout in distributed storage systems (2006)

Reliable distributed storage systems implement data distribution in several ways, but roughly considered two main principles are in common use: (i) independent local storages with shared redundancy and (ii) block striping across several storages together with redundancy. This paper is based on an analysis of these two principles. Pointing out advantages and disadvantages in several access scenarios, we propose adaptation procedures between distribution schemes. Several ways exist to adapt data from the independent local storage layout into block striping that differ in two measures: (i) the total cost; and (ii) the granularity of block movements. We found adaptation techniques that are a good tradeoff within these two measures. The adaptations can be used to change the data layout into a beneficial one for distributed access scenarios, whereby locally used data is kept in a resource-saving layout.
CHAPTER V (2010)

From Cyrus to Artaxerxes, there had at various intervals been manifested, on the part of the Persian monarchs, a desire to restore the Israelites to their ancient land of promise; and in conformity to the advice of Cyrus, (found among his archives in the castle of Ecbatana in Media,) Darius had permitted the captive Jews to return to Palestine, under the conduct of their own hereditary sovereign, Zorobabel, king of Judah, of the race of David. But if the Jews were not slow to avail themselves of their emancipation, still of the multitudes which marched out of the gates of Babylon, “to the music of lutes and cymbals,” a considerable number returned to the Persian capital, leaving but a portion of the tribes of Judah and Benjamin to proceed to the desolated city of David. In the succeeding reign, Ezra, the most considerable of the sacrificers, who, with the high priest Joachim, had remained in Babylon, accompanied a fresh reinforcement of Israelites to people the deserted streets, and re-edify the crumbled walls of Jerusalem. The influence of Esther with Artaxerxes completed the restoration of the two tribes to the land of their inheritance: the other ten remained beyond the Euphrates.
Shape specification for axially symmetric optical surfaces (2007)

Advances in fabrication and testing are allowing aspheric optics to have greater impact through their increased prevalence and complexity. The most widely used characterization of surface shape is numerically deficient, however. Furthermore, with regard to tolerancing and to constraints for manufacturability, this representation is poorly suited for design purposes. Effective alternatives are therefore presented for working with rotationally symmetric surfaces that are either (i) strongly aspheric or (ii) constrained in terms of the slope in the departure from a best-fit sphere.
Characterization of polymer molecular weight distribution by transient viscoelasticity: Polytetrafluoroethylenes (1988)

Abstract The relationship between the relaxation time spectrum H (τ) in the terminal zone and the volume‐fraction differential molecular‐weight‐distribution function P ( M ) is derived by considering binary chain contacts for stress transmission, equation image where β and λ are constants for a given chemical type. This is used to determine the molecular‐weight‐distribution curves from the stress relaxation modulus spectrum (above the crystal melting point) at 370°C for a number of commercial and experimental poly(tetrafluoroethylenes) (PTFEs). It is found that PTFEs typically have bimodal molecular‐weight distributions. The lower‐molecular‐weight peak conforms essentially to the “most‐probable” distribution, and the higher‐molecular‐weight peak to the binary coupling distribution. The entanglement molecular weight M e is 5490, and the number of main‐chain atoms between entanglement points is 110, consistent with a flexible chain. The zero‐shear melt viscosity at 370°C is η 0 = 1.79 × 10 −13 M w 2.94±0.13 , where η 0 is in Pa.s and M w / M e = 2,000 to 12,000. The monomeric friction coefficient is also determined.
Tamoxifen−Poly(ethylene glycol)−Thiol Gold Nanoparticle Conjugates: Enhanced Potency and Selective Delivery for Breast Cancer Treatment (2009)

The breast cancer treatment drug tamoxifen has been widely administered for more than three decades. This small molecule competes with 17beta-estradiol for binding to estrogen receptor, a hormone receptor upregulated in a majority of breast cancers, subsequently initiating programmed cell death. We have synthesized a thiol-PEGylated tamoxifen derivative that can be used to selectively target and deliver plasmonic gold nanoparticles to estrogen receptor positive breast cancer cells with up to 2.7-fold enhanced drug potency in vitro. Optical microscopy/spectroscopy, time-dependent dose-response data, and estrogen competition studies indicate that augmented activity is due to increased rates of intracellular tamoxifen transport by nanoparticle endocytosis, rather than by passive diffusion of the free drug. Both ligand- and receptor-dependent intracellular delivery of gold nanoparticles suggest that plasma membrane localized estrogen receptor alpha may facilitate selective uptake and retention of this and other therapeutic nanoparticle conjugates. Combined targeting selectivity and enhanced potency provides opportunities for both multimodal endocrine treatment strategies and adjunctive laser photothermal therapy.

Morphology and photoluminescence of nanoscale few-layered MoS<inf>2</inf> prepared by liquid phase exfoliation (2016)

Owing to many exotic properties and potential applications, graphene and related two-dimensional (2D) nanomaterials have attract a lot of attention. Among the various types of transition metal dichalcogenides materials, molybdenum disulfide (MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) is of technological importance in optoelectronics, sensors, energy storage, and catalysis. Exfoliation of bulk MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> is an attractive route to large-scale synthesis of few-layered or monolayered crystals. Here, we report structural, morphological and optical properties of nanoscale MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> nanosheets prepared by sonication exfoliation. The influence of sonication parameters to material properties are investigated. The absorption spectra of MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> suspension are studied. Strong photoluminescence with the peak centered at 500 nm was observed and excitation-dependent PL is studied. Our results shows that quantum confinement effects is important in the photoluminescence and it can be a way to enhance the PL intensity.
PD-L1 enhances CNS inflammation and infarct volume following experimental stroke in mice in opposition to PD-1 (2013)

Our novel observations are the first to implicate PD-L1 involvement in worsening outcome of experimental stroke. The presence of suppressor T cells in the right MCAO-inflicted hemisphere in mice lacking PD-L1 implicates these cells as possible key contributors for controlling adverse effects of ischemia. Increased expression of CD80 on APCs in WT and PD-L2-/- mice suggests an overriding interaction leading to T cell activation. Conversely, low CD80 expression by APCs, along with increased PD-1 and PD-L2 expression in PD-L1-/- mice suggests alternative T cell signaling pathways, leading to a suppressor phenotype. These results suggest that agents (for example antibodies) that can target and neutralize PD-L1/2 may have therapeutic potential for treatment of human stroke.
Cross linking of proteins <i>in vitro</i> by peroxidase (1977)

Abstract The enzyme peroxidase, a substrate (hydrogen donor), and hydrogen peroxide aggregated and polymerized soluble proteins included in the reaction mixture. Gel filtration and acrylamide disk gel electrophoresis revealed newly formed dimers, trimers, and higher protein polymers. Some of the protein polymers withstood the denaturing conditions of dodecyl sulfate disk gel electrophoresis; thus the formation of some covalent cross links was indicated. It is suggested that peroxidase catalyzes the oxidation of hydrogen donors to form free radicals or quinones, which subsequently interact with, cross link, and alter the soluble proteins.
Boron Removal Performance of a Solid Sorbent Derived from Waste Concrete (2014)

Low-cost materials for boron removal need to be developed to reduce the overall cost of treatment of boron-containing wastewater. In this paper, the preparation of a boron removal material using waste concrete particles is described. With high initial boron concentrations (100 and 300 mg/L boron), the removal performance was insufficient and the dominant boron removal mechanism was estimated to be precipitation of calcium borate. With a low initial boron concentration (10 mg/L boron), more boron was removed by increasing the amount of the sorbent, and the boron removal can be attributed to ion exchange. After heat treatment of the material at 175 °C, an initial decrease in the boron removal rates was observed, but after 1440 min the residual boron concentrations for the heat-treated material were much lower than those for the untreated material. This improvement is thought to be due to the generation of metaettringite, the dehydration product of ettringite.
