Fractional-N frequency synthesizer for wireless communications (2003)

With the advancement of radio frequency (RF) technology and requirement for more integration, new RF wireless architectures are needed. One of the most critical components in a wireless transceiver is the frequency synthesizer. It largely affects all three dimensions of a wireless transceiver design: cost, battery lifetime, and performance. The common approach to frequency synthesis design for wireless communication is to design an analog-compensated fractional-N phaselocked loop (PLL). However, this technique lacks adequate fractional spur suppression for third generation wireless standards. In this paper, a new sigma-delta PLL architecture is reported to enhance the above mentioned limitation with the aid of modified digital sigma-delta modulator to completely randomize fractional spurs present in fractional-N PLLs using feedback signal which serves as a dithering signal. This aids in fully integrating a high-performance PLL frequency synthesizer, and hence reducing cost. The use of this architecture is examined to give as much as 14 dBs reduction in the fractional spurs.
Synthesis, Characterization and Biological Activity Studies of 1,3,4-Oxadiazole Analogs (2011)

The reaction of p-bromoanilino acetohydrazide(II) with aromatic aldehydes in alcohol yielded 2-[4-bromo aniline] N-substituted benzylidine hydrazides (IIIa-IIIj), which in presence of yellow mercuric oxide and iodine in DMF, yielded corresponding 4-bromo[(N-5-substituted 1,3,4 oxadiazole-2 -yl)methyl]aniline (IVa-IVj). Structures of the compounds synthesized were confirmed by IR, (1)HNMR and MASS spectroscopic analysis. The newly synthesized compounds were screened for antibacterial, antifungal and anti-inflammatory activities. Some of the compounds showed remarkable antibacterial, antifungal and anti-inflammatory activities.
DrowsyNet: Convolutional neural networks with runtime power-accuracy tunability using inference-stage dropout (2018)

Convolutional neural networks (CNNs) have many future artificial intelligence (AI) applications; CNN hardware is an enabling technology to make this AI future come true. Two main specifications of CNN hardware are power and accuracy, which are determined at the design time by the CNN model, CNN hardware architecture, and the transformation scheme that maps the model onto the hardware. This paper points out that the above three design parameters share one common limitation that they are not flexible enough to offer power-accuracy tunability at deployment time and runtime. In response to this demand, we propose DrowsyNet, which randomly drops out a fraction of convolutional neurons to achieve a power-accuracy tradeoff. DrowsyNet is an inference-stage technique, which is different from traditional training-stage dropout. We further present that the dropout rates would better be set non-uniformly among convolutional layers. Experimental results show that up to 50% savings in the number of convolutions are available by trading away less than 11% of top-5 accuracy.
Structure of nanoporous carbon produced from titanium carbide and carbonitride (2008)

Scanning electron microscopy, X-ray diffraction and adsorption structural analyses, and helium pycnometry were used to study the structure of nanoporous carbon produced by chlorination of powdered titanium carbide and carbonitride and of titanium carbide synthesized by chemical-vapor deposition. The results obtained were used to make suggestions about the type of organization of the nanoporous structure of these materials. The evolution of the structure of nanoporous carbon was analyzed in relation to the chlorination temperature. The effect of the chlorination temperature on the structure of the nanoporous carbon obtained and on its pore volume was examined.

Memory coherence activity prediction in commercial workloads (2004)

Recent research indicates that prediction-based coherence optimizations offer substantial performance improvements for scientific applications in distributed shared memory multiprocessors. Important commercial applications also show sensitivity to coherence latency, which will become more acute in the future as technology scales. Therefore it is important to investigate prediction of memory coherence activity in the context of commercial workloads.This paper studies a trace-based Downgrade Predictor (DGP) for predicting last stores to shared cache blocks, and a pattern-based Consumer Set Predictor (CSP) for predicting subsequent readers. We evaluate this class of predictors for the first time on commercial applications and demonstrate that our DGP correctly predicts 47%-76% of last stores. Memory sharing patterns in commercial workloads are inherently non-repetitive; hence CSP cannot attain high coverage. We perform an opportunity study of a DGP enhanced through competitive underlying predictors, and in commercial and scientific applications, demonstrate potential to increase coverage up to 14%.
Isolation of a mutant strain of Pseudomonas sp. ATCC 31461 exhibiting elevated polysaccharide production (2002)

A mutant strain of the bacterium Pseudomonas sp. ATCC 31461 that exhibited elevated production of the polysaccharide gellan on glucose or corn syrup as a carbon source was isolated. Gellan production by the mutant strain was about twofold higher than its parent strain on glucose or corn syrup after 48 h of growth, and about 1.4 -fold higher after 72 h. An increase in biomass production was not correlated with enhanced gellan synthesis by the mutant strain. The increased gellan production by the mutant strain on either carbon source resulted in an increase in its culture medium viscosity and the viscosity of the isolated polysaccharide produced by glucose -grown cells. No differences in the glucuronic acid content of the polysaccharides produced by the mutant and parent strains were observed.
Allelic loss of distal chromosome 4 in mouse lung tumors localize a putative tumor suppressor gene to a region homologous with human chromosome 1p36. (1995)

Loss of heterozygosity (LOH) of distal chromosome 4 was studied to localize a putative tumor suppressor gene in mouse lung neoplasia. Previous studies have implicated this region and its homologue on human chromosome 1p36-34 as sites of potential tumor suppressor genes. One hundred adenocarcinomas and 38 adenomas of the mouse lung were examined for LOH using nine simple sequence length polymorphism markers in a polymerase chain reaction-based approach. Forty-four adenocarcinomas displayed allele loss, all of which included losses at marker D4MIT54, which defined a critical region of 3 centiMorgans as the likely location of a putative tumor suppressor gene. In 58% of the tumors displaying LOH, all markers used in this study incurred allele loss. In contrast, retention of heterozygosity was observed at all markers tested in each of the adenomas studied, which suggests that the inactivation of this tumor suppressor gene participates in mouse lung tumor progression.

Detailed deletion mapping of chromosome 9p and p16 gene alterations in human borderline and invasive epithelial ovarian tumors. (1995)

We used PCR amplification of tandem repeats to study the pattern of allelic loss in borderline and invasive ovarian epithelial tumors using 12 primer pairs to generate a detailed deletion map of chromosome 9p. In the invasive ovarian carcinomas, there were three regions displaying high frequency of loss of heterozygosity (LOH) ranging from 31-38%. In contrast, LOH was a rare event among the borderline ovarian tumors, with one region revealing a rate of 20% and the remaining regions only 0-8% LOH. Therefore, allelic loss does not seem to be important for the development of borderline ovarian tumors. We also examined p16 gene expression and mutations in ovarian cancer cell lines and invasive and borderline ovarian tumor tissues. Southern blot analysis revealed no losses of the p16 gene in either the invasive or borderline ovarian tumors. However, the ovarian carcinoma cell lines showed a 50% homozygous deletion rate. SSCP analysis detected a mobility shift in only one (borderline) tumor. Since the primary invasive ovarian tumors did not show any deletions or mutations, it appears that p16 does not play a role in the pathogenesis of these tumors.
Dimension and Product Structure of Hyperbolic Measures (1999)

We prove that every hyperbolic measure invariant under a C 1+α diffeomorphism of a smooth Riemannian manifold possesses asymptotically "almost" local product structure, i.e., its density can be approximated by the product of the densities on stable and unstable manifolds up to small exponentials.This has not been known even for measures supported on locally maximal hyperbolic sets.Using this property of hyperbolic measures we prove the long-standing Eckmann-Ruelle conjecture in dimension theory of smooth dynamical systems: the pointwise dimension of every hyperbolic measure invariant under a C 1+α diffeomorphism exists almost everywhere.This implies the crucial fact that virtually all the characteristics of dimension type of the measure (including the Hausdorff dimension, box dimension, and information dimension) coincide.This provides the rigorous mathematical justification of the concept of fractal dimension for hyperbolic measures.
Thermally stable AlGaAs/GaAs microwave power HBT's (1993)

Novel thermal shunt and thermal lens techniques have been used in the design of multiple-emitter AlGaAs/GaAs power HBTs (heterojunction bipolar transistors). Thermal stabilization was achieved by the use of a thick metal bridge connecting all emitters. The thickness of the bridge was designed to assure a virtual thermal short between emitters. The use of such a thermal shunt element redistributes temperature-dependent internal device currents to force an equalization of device junction temperature. The bridge further serves to spread heat from each emitter over a larger GaAs surface (thermal lens), thereby reducing overall device thermal resistance. Multiemitter devices with 2 mu m and 3 mu m minimum emitter feature sizes were fabricated and tested at microwave frequencies to demonstrate the thermally stable operation.
Aerosol and cloud condensation nuclei measurements in the Kuwait plume (1992)

Fast response in situ particle measurements within the Kuwait oil smoke plume showed that about 70% of the particles are cloud condensation nuclei (CCN) active at about 1% super saturation. The CCN size range included the entire measured particle size range between 0.024 and 1 μm. The portion of the aerosol spectrum below 0.1 μm appeared to be internally mixed (various compositions within each particle), while the larger particles tended to be externally mixed (various compositions for different particles but homogeneous composition within each particle). The majority of the CCN are very water soluble (critical supersaturations below 0.2%). This significant CCN source could have important climatic effects by altering cloud albedo and precipitation. However, cloud scavenging will reduce the atmospheric lifetimes of the particles, which is an important consideration in large‐scale atmospheric injections such as nuclear winter scenarios.
Cost-effective analysis of in-place software processes (1998)

Process studies and improvement efforts typically call for new instrumentation on the process in order to collect the data they have deemed necessary. This can be intrusive and expensive, and resistance to the extra workload often foils the study before it begins. The result is neither interesting new knowledge nor an improved process. In many organizations, however, extensive historical process and product data already exist. Can these existing data be used to empirically explore what process factors might be affecting the outcome of the process? If they can, organizations would have a cost-effective method for quantitatively, if not causally, understanding their process and its relationship to the product. We present a case study that analyzes an in-place industrial process and takes advantage of existing data sources. In doing this, we also illustrate and propose a methodology for such exploratory empirical studies. The case study makes use of several readily available repositories of process data in the industrial organization. Our results show that readily available data can be used to correlate both simple aggregate metrics and complex process metrics with defects in the product. Through the case study, we give evidence supporting the claim that exploratory empirical studies can provide significant results and benefits while being cost effective in their demands on the organization.
An MRM-Based Multiplexed Quantification Assay for Human Adipokines and Apolipoproteins (2020)

Adipokines and apolipoproteins are key regulators and potential biomarkers in obesity and associated diseases and their quantitative assessment is crucial for functional analyses to understand disease mechanisms. Compared to routinely used ELISAs, multiple reaction monitoring (MRM)-based mass spectrometry allows multiplexing and detection of proteins for which antibodies are not available. Thus, we established an MRM method to quantify 9 adipokines and 10 apolipoproteins in human serum. We optimized sample preparation by depleting the two most abundant serum proteins for improved detectability of low abundant proteins. Intra-day and inter-day imprecision were below 16.5%, demonstrating a high accuracy. In 50 serum samples from participants with either normal weight or obesity, we quantified 8 adipokines and 10 apolipoproteins. Significantly different abundances were observed for five adipokines (adipsin, adiponectin, chemerin, leptin, vaspin) and four apolipoproteins (apo-B100/-C2/-C4/-D) between the body mass index (BMI) groups. Additionally, we applied our MRM assay to serum samples from normal weight children and human adipocyte cell culture supernatants to proof the feasibility for large cohort studies and distinct biological matrices. In summary, this multiplexed assay facilitated the investigation of relationships between adipokines or apolipoproteins and phenotypes or clinical parameters in large cohorts, which may contribute to disease prediction approaches in the future.
Time trends in primary resistance to HIV drugs in the United Kingdom: multicentre observational study (2005)

Optical Architecture For Acousto-Optic Space Integrating Correlator (1988)

An architecture for a real-time signal correlation based on optical joint transform correlation is proposed. Two parallel on-plane acousto-optic (AO) cells and square-law converter are employed to produce cross correlation of two electrical signals. Arrangement of the two AO cells on the same plane permits this architecture to be implemented in a compact form. The proposed architecture has a capability of performing parallel multiple cross correlations by addition of AO cells on the input plane. The theoretical analysis and preliminary experimental results are presented.
Cinnamoyl shell-modified poly(amidoamine) dendrimers (2000)

Poly(amidoamine)(PAMAM) dendrimers with a cinnamoyl shell were prepared by reacting full generation PAMAM dendrimers (G=3.0) with 2-chloroethanol and cinnamoyl chloride, which resulted in densely packed polymerizable unsaturated groups on the periphery. The cinnamoyl shell of the dendrimers dimerized when irradiated under a UV light by using 5-nitroacenaphthylene as an initiator in dilute dimethylformamide (DMF). FTIR, 1H NMR, UV-Vis, SEC, and a viscosity test certified that the photocycloaddition of the cinnamoyl shell of the dendrimers took place within the molecules with the disappearance of double bond signals in the FTIR. 1H NMR spectra as well as the intrinsic viscosity and polydispersity value of the products both before and after irradiation showed no difference. It was further found that the cinnamoyl shell-modified dendrimers possessed fluorescence property, and the fluorescence intensity became stronger when the shell was photocyclized under UV- irradiation. © 2000 John Wiley & Sons, Inc.

Dissimilation of Aromatic Compounds by<i>Alcaligenes eutrophus</i> (1971)

The range of aromatic compounds that support the growth of Alcaligenes eutrophus has been determined, and the pathways used for the dissimilation of these substrates have been explored, largely by enzymatic analyses. The beta-ketoadipate pathway operates in the dissimilation of benzoate and p-hydroxybenzoate; the genetisate pathway, in the dissimilation of m-hydroxybenzoate; and the meta cleavage pathway, in the dissimilation of phenol and p-cresol. l-Tryptophan is oxidized via anthranilate; but the metabolic fate of anthranilate was not established. The metabolism of the three stereoisomers of muconic acid was also examined.
Delayed short-course treatment with teriparatide (PTH1–34) improves femoral allograft healing by enhancing intramembranous bone formation at the graft–host junction (2011)

Clinical management of critical bone defects remains a major challenge. Despite preclinical work demonstrating teriparatide (PTH(1-34)) effectiveness in small animals, inconclusive data from clinical trials have raised questions of dose and regimen. To address this, we completed a comprehensive study in the murine femoral allograft model, to assess the effects of dose (0.4, 4, and 40 µg/kg/day) and various treatment regimens on radiographic, histologic, and biomechanical healing at 2, 4, and 9 weeks. Only the high dose (40 µg/kg) of PTH(1-34) demonstrated significant effects when given daily over 9 weeks. Remarkably, equivalent biomechanical results were obtained with delayed, short treatment from 2 to 6 weeks that did not induce a significant increase in endochondral bone formation and callus volume. In contrast, PTH(1-34) treatment from 1 to 5 weeks postop demonstrated similar osteogenic effects as immediate daily treatment for 9 weeks, but failed to achieve a significant increase in biomechanics at 9 weeks. MicroCT and histologic analyses demonstrated that the 2-week delay in treatment allowed for timely completion of the endochondral phase, such that the prominent effects of PTH(1-34) were enhanced intramembranous bone formation and remodeling at the graft-host junction. These findings support the potential use of PTH(1-34) as an adjuvant therapy for massive allograft healing, and suggest that there may be an ideal treatment window in which a short course is administered after the endochondral phase to promote osteoblastic bone formation and remodeling to achieve superior union with modest callus formation.
The stationary value of axially symmetric functions: part II (1926)

Alternative methods to those described in Part I of constructing a series representing the stationary value of a given function are developed and applied to evaluate all the terms not involving powers and products of the coefficients of the function higher than the eleventh. The formula in its optical applications enables the first 451 monorythmic aberrations of a symmetrical optical instrument to be determined.
Resolution enhancement with high-transmission attenuating phase-shift masks (1999)

Experiments to print 140 nm lines and 140 nm contact holes were optimized through simulation on an 18% transmitting phase shift mask for KrF lithography. A transmittance of 18% is to improve aerial image log slope through focus for the lines and contacts. The 140 nm lines for all three pitches have a maximum depth of focus of at least 0.90 micrometer. The exposure latitude of the 140 nm lines is over 7.5% for all pitches to maintain 0.6 micrometer depth of focus. Experiments show that the 140 nm and 160 nm contact holes resolve without side lobe printing through focus and through exposure. Reticle SEMs verify that a ternary contact hole mask is capable of manufacture. By adding both opaque and clear sub-resolution assist features, the experiments show contacts as small as 140 nm resolve with 0.50 micrometer focus latitude with 10% exposure latitude through pitch. Cross sectional SEMs verify that 140 nm contact holes are open through pitch. Simulations to quantify the MEF show that the MEF for attenuating PSM decreases as the transmittance of the attenuating material increases. The MEF for a 30% transmitting attenuating material is 1.90 for a 150 nm feature and the MEF for an alternating PSM is 1.42 for the same 150 nm feature. Trends in aerial image CD variation due to aberrations were simulated for focal plane deviation, x coma, astigmatism and spherical aberrations. The simulations of alternating PSM imaged with (sigma) of 0.35 suggest that alternating PSM have the least CD variation due to focal plane deviation, astigmatism, and coma for dense pitches. The CD variation due to coma is comparable to 33% transmittance attenuating PSM for isolated lines. Furthermore alternating PSM is more susceptible for CD placement error due to coma compared to attenuating PSM. The 33% transmittance attenuating PSM has the least CD variation due to spherical aberration in comparison to BIM and alternating PSM.
