Application of dynamic synapse neural networks on identification and localization of nonspeech sounds (2004)

This paper focuses on the dynamic synapses neural network (DSNN) for identification of nonspeech sounds, including the chambering of a gun, as well as localization of identified sounds. The algorithm employed consisted of extracting DSNN features from sounds and classification of features based on Gaussian mixture models (GMMs). To extract DSNN features, a single neuron with a presynapse including a 14th order differential equation, first order post-synapse, and first order inhibitory feedback was used. After training, network parameters were used as features. The classification task was then formulated as an estimation of conditional joint probability. Classification results were collected from both chambering identification and localization. Successful localization was defined as correct identification of speaker of origin. The number of training and testing samples were 120 and 160, respectively. The system performed 96.88% and 90.00% correct identification and localization of test samples.
Gold nanoparticles promote the catalytic activity of ceria for the transalkylation of propylene carbonate to dimethyl carbonate (2009)

A series of metal oxide nanoparticles with acid or basic properties exhibit low to moderate activity towards the transalkylation of propylene carbonate with methanol; deposition of gold nanoparticles on nanoparticulated ceria significantly increases the activity of this metal oxide towards transalkylation.
Macroglobulinemia and Hairy-Cell Leukemia (1977)

Leukemic reticuloendotheliosis, or hairy-cell leukemia, is a distinct clinical entity characterized by the proliferation of cells that have prominent cytoplasmic projections and contain the tartrate-resistant isozyme 5 of acid phosphatase.1 2 3 Although the clinical and morphologic features of this disease are widely known, there is considerable disagreement over whether the leukemic cell belongs to the lymphocyte or monocyte lineage.4 In the unusual case of hairy-cell leukemia reported below, the leukemic cells produced a monoclonal IgM, thereby substantiating the lymphocyte derivation of the neoplastic cells in this patient. The findings emphasize the wide clinical and biologic spectrum of B-cell neoplasms.Case History . . .
A Practical Approach to Decentralized Intersection Access Control for Autonomous Vehicles (2017)

In a shift from the current research trend which is mostly geared towards centralizing access control of autonomous vehicles at intersection of the near future, the authors extend their previously presented intersection management model, which is fully decentralized. Even though it is the most efficient, central control requires fully automated connected vehicles, active vehicle-to-vehicle and vehicle-to-infrastructure communications, which introduces inherent security, privacy and feasibility issues. We simulate autonomous intelligent vehicles making local access decisions at isolated intersections, with only sensing and/or beacon information. The simulation proves to be collision-free. The extended management model is now able to account for various vehicle classes, all possible turns at the intersection and safe turning speeds. Compared to a standard signal controller, the proposed and improved model is again proven to be operationally more efficient.

Architectural Support for Efficient Data Movement in Disaggregated Systems (2023)

Resource disaggregation offers a cost effective solution to resource scaling, utilization, and failure-handling in data centers by physically separating hardware devices in a server. Servers are architected as pools of processor, memory, and storage devices, organized as independent failure-isolated components interconnected by a high-bandwidth network. A critical challenge, however, is the high performance penalty of accessing data from a remote memory module over the network. Addressing this challenge is difficult as disaggregated systems have high runtime variability in network latencies/bandwidth, and page migration can significantly delay critical path cache line accesses in other pages. This paper introduces DaeMon, the first software-transparent and robust mechanism to significantly alleviate data movement overheads in fully disaggregated systems. First, to enable scalability to multiple hardware components in the system, we enhance each compute and memory unit with specialized engines that transparently handle data migrations. Second, to achieve high performance and provide robustness across various network, architecture and application characteristics, we implement a synergistic approach of bandwidth partitioning, link compression, decoupled data movement of multiple granularities, and adaptive granularity selection in data movements. We evaluate DaeMon in a wide variety of workloads at different network and architecture configurations using a state-of-the-art accurate simulator and demonstrate that DaeMon significantly improves system performance and data access costs over the widely-adopted approach of moving data at page granularity.
Sir-two-homolog 2 (Sirt2) modulates peripheral myelination through polarity protein Par-3/atypical protein kinase C (aPKC) signaling (2011)

The formation of myelin by Schwann cells (SCs) occurs via a series of orchestrated molecular events. We previously used global expression profiling to examine peripheral nerve myelination and identified the NAD(+)-dependent deacetylase Sir-two-homolog 2 (Sirt2) as a protein likely to be involved in myelination. Here, we show that Sirt2 expression in SCs is correlated with that of structural myelin components during both developmental myelination and remyelination after nerve injury. Transgenic mice lacking or overexpressing Sirt2 specifically in SCs show delays in myelin formation. In SCs, we found that Sirt2 deacetylates Par-3, a master regulator of cell polarity. The deacetylation of Par-3 by Sirt2 decreases the activity of the polarity complex signaling component aPKC, thereby regulating myelin formation. These results demonstrate that Sirt2 controls an essential polarity pathway in SCs during myelin assembly and provide insights into the association between intracellular metabolism and SC plasticity.

We present results of the enhancement mode, n-channel 3C-silicon carbide (SiC) MOSFETs fabricated on homoepitaxy 3C-SiC films. The fabricated devices exhibit excellent gate-controlled linear and saturation regimes of operation. The average effective channel mobility is found to be 229 cm/sup 2//Vs. The breakdown field of the gate oxide is observed at be 11 MV/cm and the subthreshold swing is determined to be 280 mV/decade.
Relationships of Plant Density and Harvest Index to Seed Yield and Quality in Carrot (1988)

Abstract Carrot ( Daucus carota L. cv. Danvers) seed were produced at plant spacings of 0.05, 0.10, 0.20, and 0.30 m in 0.80-m rows to give populations of 25, 13, 6, and 4 plants/m 2 . Samples from the adjacent commercial carrot seed field provided an additional density of 36 plants/m 2 . Seed yield, harvest index, and seed quality were evaluated with respect to umbel order and plant density. Phenological development was unaffected by plant density, but plant height increased significantly as density increased. The number of umbels per plant and the number of seeds per umbel decreased with increasing plant density, while seed weight was unaffected. The proportion of the seed contributed by primary umbels increased from 20% at the lowest to 60% at the highest density. Seed yield per plant declined continuously as population increased, but seed yield per unit area increased to a maximum at 12 plants/m 2 , then declined. Total biological yield (above-ground biomass) rose to a plateau level with increasing plant population. Ceiling biological yield coincided with maximum seed yield. Seed quality within each umbel order, assessed by germination percentage and rate, seedling growth, embryo length, and abnormal or embryoless seeds, was unaffected by plant density, but consistently decreased from primary to tertiary umbel orders. Harvest index (seed yield/biological yield) was highly correlated with seed quality. The relationship between harvest index and plant density in carrot seed production may be useful in optimizing plant populations for maximum seed yield and quality.
Generation of coherent XUV radiation in the water window (1998)

Summary form only given. He atoms driven coherently by intense laser pulses in the quasi-single-cycle regime are capable of emitting (spatially) coherent X-rays with photon energies in excess of 0.5 keV. Propagation effects have been found to play a dramatic role in shaping the XUV spectrum at high photon energies. Careful optimization of the operating regime will allow the realization of an efficient ultrafast laser-pumped coherent XUV sources at high photon energies.
An adaptive close-talking microphone array (2002)

Directional microphones are best noted for their noise reduction properties in communication systems. Close-talking differential microphones are particularly useful when the noise environment disturbs the ability to communicate without error, such as in public and cellular telephony, aircraft communications, etc. These differential microphones work best when they are spaced within 1 cm from the lips of the talker where the sound field has a large gradient. For a plane-wave sound field, the sensitivity rises proportional to /spl omega//sup n/ where n is the order of the difference. Users of differential microphones do not always correctly position the sensor at the proper distance from the mouth and therefore the sensitivity of the microphone may also rise proportional to /spl omega//sup n/ especially at high frequencies. We describe a method of correcting for this high frequency gain without significantly degrading the noise canceling properties of first and second-order differential microphones.
HSD3B1 and resistance to androgen deprivation therapy in prostate cancer. (2016)

5015 Background: The somatic mutation HSD3B1(1245A > C) has been mechanistically linked to castration-resistant prostate cancer by encoding a mutant enzyme that augments intratumoral dihydrotestosterone (DHT) synthesis. Given the HSD3B1(1245C) allele is also frequently found in the germline, we hypothesized men inheriting this variant allele would exhibit resistance to androgen deprivation therapy (ADT). Methods: We determined HSD3B1 genotype retrospectively in men treated with ADT for post-prostatectomy biochemical failure. We analyzed progression-free survival (PFS), distant metastasis-free survival (DMFS), and overall survival (OS) according to HSD3B1 genotype using Kaplan-Meier methods. Demographic and treatment characteristics were compared to assess for potential confounders using Fisher’s exact test and Kruskal-Wallis analysis of variance. Multivariable analyses were performed to assess the independent predictive value of HSD3B1 genotype on outcomes. Results were independently validated in two external cohorts, including a second post-prostatectomy cohort and a metastatic cohort. Results: 443 patients were included: 118 in the primary cohort, 137 in the post-prostatectomy validation cohort, and 188 in the metastatic validation cohort. In the primary cohort, median PFS diminished as a function of the number of variant alleles inherited (6.6 years in homozygous wild-type men, 4.1 years in heterozygotes, and 2.5 years in homozygous variants; P = 0.01). Median DMFS likewise diminished according to the number of variant alleles inherited (9.1 vs. 6.8 vs. 3.6 years, respectively; P = 0.01). Finally, OS decreased with the number of variant alleles inherited (5-year and 10-year OS: 82% and 55% vs. 74% and 35% vs. 58% and 0%; P = 0.006). On multivariable analysis, the impact of HSD3B1 genotype on metastasis (hazard ratio (HR) 2.8; P = 0.023) and death (HR 3.3; P = 0.016) was maintained. Findings in the external cohorts independently validated the profound impact of HSD3B1(1245C) on outcomes, including overall survival. Conclusions: Inheritance of the HSD3B1(1245C) allele that enhances dihydrotestosterone synthesis predicts innate resistance to ADT in prostate cancer.

Effect of Carbon Nanotube Aqueous Dispersion Quality on Mechanical Properties of Cement Composite (2012)

An effect of the quality of carbon nanotube (CNT) dispersions added to cement on paste mechanical properties has been studied. High‐quality dispersions of few‐walled CNT (FWCNTs) were produced in two steps. First, FWCNTs were functionalized in a mixture of nitric and sulfuric acids (70 wt.% and 96 wt.%, resp.) at 80 ∘ C. Second, functionalized FWCNTs were washed out by acetone to remove carboxylated carbonaceous fragments (CCFs) formed during CNT oxidation. Mechanical test results showed 2‐fold increase in the compressive strength of the cement paste prepared from the dispersion of acetone‐washed functionalized FWCNTs, which is believed to occur due to the chemical interaction between cement matrix and functional groups (–COOH and –OH). Utilisation of unwashed FWCNTs led to a marginal improvement of mechanical properties of the cement pastes, whereas surfactant‐treated functionalized FWCNT dispersions only worsened the mechanical properties.
Fluorescence imaging and spectroscopy of biomaterials in air and liquid by scanning near-field optical/atomic force microscopy. (1996)

We have developed scanning near-field optical/atomic force microscopy (SNOM/AFM). The SNOM/AFM uses a bent optical fiber simultaneously as a dynamic force AFM cantilever and a SNOM probe. Resonant frequency of the optical fiber cantilever is 15-40 kHz. Optical resolution of the SNOM/AFM images shows less than 50 nm. The SNOM/AFM system contains photon counting system and polychrometer/intensified coupled charge devise (ICCD) system to observe fluorescence image and spectrograph of micro areas, respectively. Cultured cells were stained with fluorescein isothiocyanate (FITC)-labeled anti-keratin antibody or FITC-labeled phalloidin after treatment with Triton X-100. Fluorescence and topographic images were obtained in air and water. The fluorescence images showed clear images of keratin and actin filaments. The SNOM/AFM is perfect to observe biomaterials in liquid with a liquid chamber while the topographic Images showed subcellular structures which correspond to keratin and actin filaments.

Synthesis and (Non)linear Optical Properties of a Series of Donor−Oligopyrrole−Acceptor Molecules (1998)

The Pd-catalyzed cross-coupling reaction involving organostannanes (Stille reaction) is applied to prepare a series of N-t-BOC-protected D−π−A oligopyrroles. After purification, oligomers with one to four pyrrole units inserted between a 4-nitrophenyl and a 4-methoxyphenyl group are isolated in yields between 20 and 47%. Only minor differences in the linear optical properties are observed for the four oligomers. The charge-transfer band around λmax = 365 nm shows a small, unexpected, hypsochromic shift, while the π−π* band around λmax = 285 nm shows a small, expected, bathochromic shift upon elongation of the molecule. Their nonlinear optical properties, however, show a surprising proceeding; going from the D−π−A oligomer with one pyrrole unit to that with three pyrrole units, the hyperpolarizability, as measured by hyper-Rayleigh scattering, increases additionally with the number of pyrrole units within the oligomer, up to 277 × 10-30 esu in case of the trimer. On the basis of the assumption that both transitions contribute to the hyperpolarizability, a better conjugated D−π−A oligomer with a bithienyl spacer inserted between a 2-(4-nitrophenyl)-5-pyrrolyl and a 2-(4-methoxyphenyl)-5-pyrrolyl group is prepared analogously. This molecule shows only one combined absorption at λmax = 378 nm for both the charge transfer and the π−π* band, while the hyperpolarizability is as high as 440 × 10-30 esu. These data, showing a very favorable transparency−hyperpolarizability tradeoff, are explained in terms of the contribution of two transitions that are superimposed.
Detection and Prognostics on Low-Dimensional Systems (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper describes the application of known and novel prognostic algorithms on systems that can be described by low-dimensional, potentially nonlinear dynamics. The methods rely on estimating the conditional probability distribution of the output of the system at a future time given knowledge of the current state of the system. We show how to estimate these conditional probabilities using a variety of techniques, including bagged neural networks and kernel methods such as Gaussian process regression (GPR). The results are compared with standard method such as the nearest neighbor algorithm. We demonstrate the algorithms on a real-world dataset and a simulated dataset. The real-world dataset consists of the intensity of an <formula formulatype="inline"><tex Notation="TeX">${\rm NH}_3$</tex></formula> laser. The laser dataset has been shown by other authors to exhibit low-dimensional chaos with sudden drops in intensity. The simulated dataset is generated from the Lorenz attractor and has known statistical characteristics. On these datasets, we show the evolution of the estimated conditional probability distribution, the way it can act as a prognostic signal, and its use as an early warning system. We also review a novel approach to perform GPR with large numbers of data points. </para>
Search for single vector-like B quark production and decay via B → bH($$ b\overline{b} $$) in pp collisions at $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector (2023)

A bstract A search is presented for single production of a vector-like B quark decaying into a Standard Model b -quark and a Standard Model Higgs boson, which decays into a $$ b\overline{b} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>b</mml:mi> <mml:mover> <mml:mi>b</mml:mi> <mml:mo>¯</mml:mo> </mml:mover> </mml:math> pair. The search is carried out in 139 fb − 1 of $$ \sqrt{s} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> = 13 TeV proton-proton collision data collected by the ATLAS detector at the LHC between 2015 and 2018. No significant deviation from the Standard Model background prediction is observed, and mass-dependent exclusion limits at the 95% confidence level are set on the resonance production cross-section in several theoretical scenarios determined by the couplings c W , c Z and c H between the B quark and the Standard Model W , Z and Higgs bosons, respectively. For a vector-like B occurring as an isospin singlet, the search excludes values of c W greater than 0.45 for a B resonance mass ( m B ) between 1.0 and 1.2 TeV. For 1 . 2 TeV &lt; m B &lt; 2 . 0 TeV, c W values larger than 0.50–0.65 are excluded. If the B occurs as part of a ( B, Y ) doublet, the smallest excluded c Z coupling values range between 0.3 and 0.5 across the investigated resonance mass range 1 . 0 TeV &lt; m B &lt; 2 . 0 TeV.
INFLUENCE OF COLD ROLLING ON THE MECHANICAL AND TECHNOLOGICAL PROPERTIES OF AHSS STEEL GRADES (2017)

This report gives in the first part the metallurgical basics for the production of AHSS grades in integrated steel plants starting at the melt shop and ending at the annealing lines of the cold mill. The corresponding process and plant technologies in each production step with its specifics and rules are explained. In the second part by way of example the practical requirements for TRIP 780 steel grade are highlighted like a recipe for process control in the steel plant, hot and cold rolling mill, annealing line and finally skin pass mill. Measuring of mechanical technological properties on samples shows that the specifications according to DIN EN 10268 are fulfilled.
Involvement of a second lymphoid-specific enhancer element in the regulation of immunoglobulin heavy-chain gene expression. (1990)

To determine whether enhancer elements in addition to the highly conserved octamer (OCTA)-nucleotide motif are important for lymphoid-specific expression of the immunoglobulin heavy-chain (IgH) gene, we have investigated the effect of mutating the binding site for a putative additional lymphoid-specific transcription factor, designated NF-microB, in the murine IgH enhancer. We demonstrate that the NF-microB-binding site plays a critical role in the IgH enhancer, because mutation of the microB DNA motif decreased transcriptional activity of the IgH enhancer in cells of the B-cell lineage but not in nonlymphoid cells. This effect was comparable to or even stronger than the effect of a mutation in the OCTA site. Moreover, combined mutation of both microB and OCTA sites further reduced enhancer activity in lymphoid cells. Interestingly, alteration of either the microB or E3 site in a 70-base-pair fragment of the IgH enhancer that lacks the binding site for OCTA abolished enhancer activity in lymphoid cells completely. Nevertheless, a multimer of the microB motif alone showed no enhancer activity. DNase footprinting analysis corroborated the functional data showing that a lymphoid-specific protein binds to the microB DNA motif. Our results suggest that the microB element is a new crucial element important for lymphoid-specific expression of the IgH gene but that interaction with another enhancer element is essential for its activity.
