High frequency characterization and recording performance of NiFe and laminated FeN heads (1996)

A simple high frequency characterization technique extended from DC disk erasure is presented to measure the write field degradation for frequencies up to 500 Mfc/s (250 MHz) on plated NiFe and sputtered laminated FeN heads. The results show that eddy currents appear to be the main cause for high frequency write field degradation. Overwrite recording measurements, which may be used to approximate the non-linear write effects, also indicate that FeN heads, despite low efficiency, may be adequate for writing up to 100 MHz on a disk with a coercivity of 2500 Oe. This disk is capable of supporting 5-10 Gb/in/sup 2/ densities.
Flexible tubular replicas of abdominal aortic aneurysms (2002)

The aim of this study was to manufacture life-size, flexible, tubular replicas of human abdominal aortic aneurysms and the associated vasculature, suitable for use in a training simulator for endovascular procedures. Selective laser sintering was used to create a geometrically correct master model for each of ten anatomical variations. The masters were used to generate flexible latex replicas. The use of the replicas in the training simulator was demonstrated. In total ten silicone rubber models were produced. When connected into the training simulator and perfused at arterial pressure it was possible to deploy an endovascular stent under fluoroscopic control and to perform angiography. The study has shown that conventional rapid prototyping technology can be used to manufacture flexible, radiolucent replicas which provide a realistic training environment for endovascular procedures.
Electrolysis in the presence of ultrasound: cell geometries for the application of extreme rates of mass transfer in electrosynthesis (1997)

Two types of sonoelectrochemical reactors for preparative synthetic work are suggested and characterized by their performance in the reversible one electron reduction of cobalticenium cations in acetonitrile solution. The dominant effect of ultrasound is to strongly agitate the liquid phase and the corresponding parameters (mass transport coefficients) for the transport at the electrode surface are reported. An upper limit for ultrasound induced mass transport at macroelectrodes an order of magnitude beyond that achieved in conventional electrolysis is described. Further, for a synthetic scale reaction, the reductive ring opening of the α,β-epoxyketone isophorone oxide to yield the corresponding β-hydroxyketone, an improved current efficiency (3 F for a direct two electron reduction) and a clean conversion (yields up to 80% isolated) are demonstrated. The extremely high rates of mass transport achieved in the presence of ultrasound considerably enhance the performance and current efficiency in electrosynthesis by selectively increasing the rates of the mass transport controlled processes.
Response to comment on ‘Tumour-infiltrating inflammation and prognosis in colorectal cancer: systematic review and meta-analysis’ (2014)

We read with interest the recent meta-analysis by Mei et al (2014). In this study, Mei et al examined the prognostic value of the local inflammatory infiltrate in colorectal cancer as measured by both the generalised inflammatory infiltrate and by immunohistochemical analysis of T-lymphocytic subsets. The authors concluded that, in comparison with assessment of T-cell subset density, semiquantitative assessment of the generalised inflammatory infiltrate at the invasive margin, utilising the Jass score or Klintrup-Ma kinen grade Indeed, in patients undergoing resection for Stage I-III disease, a high-density generalised inflammatory infiltrate was associated with an almost 60% increase in overall survival.
Lock-in common-mode rejection demodulation: Measurement technique and applications to thermal-wave detection. Experimental (2000)

A new signal generation methodology based on lock-in amplifier common mode rejection demodulation for materials nondestructive evaluation has been implemented experimentally with thermal waves in a photothermal radiometric apparatus. A procedure to calibrate the experiment is described in order to take into account instrumental time delay phase shifts between the reference and the optical excitation wave form. Some preliminary results obtained on Zr–2.5Nb shot peened samples are presented and compared to those obtained by temporally modulating the pump intensity as a 50% duty cycle square wave. The comparison shows the new measurement methodology to be a very promising technique for nondestructive evaluation and depth profiling applications, featuring high detectivity for low-dynamic-range and poor-signal to noise ratio signals, such as those obtained with thermal-wave diagnostics.
Why Do Mortality Rates for Nonvariceal Upper Gastrointestinal Bleeding Differ around the World? A Systematic Review of Cohort Studies (2012)

Wide differences in reported NVUGIB mortality rates are attributable to differences in adopted methodologies and populations studied. More uniform standards in reporting are needed; only then can true observed variations enable a better understanding of causes of death and pave the way to improved patient outcomes.
Optical associative memory model based on neural networks having variable interconnection weights (1987)

A new model is proposed for a content-addressable memory (CAM) based on neural networks. Like the previous Hopfield model, the information is stored in the structure of the network and the read-out procedure may be implemented in the form of an optical vector-matrix multiplier. This model introduces intermediate layers of interneurons between the neuron layers and a dependence of the interconnection weights to a given neuron on the previous history of the neuron. The storage prescription allows each matrix element to have three values instead of only two as in the previous Hopfield model. This more complex model gives better results than the Hopfield model.
A comparison of signal processing front ends for automatic word recognition (1995)

This paper compares the word error rate of a speech recognizer using several signal processing front ends based on auditory properties. Front ends were compared with a control mel filter bank (MFB) based cepstral front end in clean speech and with speech degraded by noise and spectral variability, using the TI-105 isolated word database. MFB recognition error rates ranged from 0.5 to 26.9% in noise, depending on the SNR, and auditory models provided error rates as much as four percentage points lower. With speech degraded by linear filtering, MFB error rates ranged from 0.5 to 3.1%, and the reduction in error rates provided by auditory models was less than 0.5 percentage points. Some earlier studies that demonstrated considerably more improvement with auditory models used linear predictive coding (LPC) based control front ends. This paper shows that MFB cepstra significantly outperform LPC cepstra under noisy conditions. Techniques using an optimal linear combination of features for data reduction were also evaluated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Numerical simulation of single crystal growth by submerged heater method (1990)

A novel method of crystal growth which utilizes an axial submerged heater is proposed and numerically simulated. Single crystals should be grown by directional solidification in vertical bottom seeded crucibles. Submerged in the melt, the heater supplies the heat axially downward, enclosing and stratifying a small active portion of the melt.
Monitoring of timed discrete events systems: Application to manufacturing systems (2006)

In this paper, we develop a method for fault detection based on stopwatch automata. This method takes into account the exact behavior of some physical resources. Because of a malfunction, some system tasks can be stopped and resumed a little later. Thus, we introduce the concept of an acceptable system behavior which is supposed to be observable. It is supervised by two clocks for each task. The timed state space of the stopwatch automaton delimits exactly the acceptable system behavior. It permits to detect the fault as early as possible. This space is a set of the inequality constraints where any violation of these constraints represents a fault
Identification of gene expression patterns in superficial and invasive human bladder cancer. (2001)

Multiple transcriptional events take place when normal urothelium is transformed into tumor tissue. These can now be monitored simultaneously by the use of oligonucleotide arrays, and expression patterns of superficial and invasive tumors can be established. Single-cell suspensions were prepared from bladder biopsies (36 normal, 29 tumor). Pools of cells were made from normal urothelium and from pTa grade I and II and pT2 grade III and IV bladder tumors. From these suspensions, and from 10 single-tumor biopsies, labeled cRNA was hybridized to oligonucleotide arrays carrying probes for 6500 genes. The obtained expression data were sorted according to a weighting scheme and were subjected to hierarchical cluster analysis of tissues and genes. Northern blotting was used to verify the array data, and immunohistology was used to correlate between RNA and protein levels. Hierarchical clustering of samples correctly identified the stage using both 4076 genes and a subset of 400 genes covarying with the stages and grades of tumors. Hierarchical clustering of gene expression levels identified several stage-characteristic, functionally related clusters, encoding proteins that were related to cell proliferation, oncogenes and growth factors, cell adhesion, immunology, transcription, proteinases, and ribosomes. Northern blotting correlated well with array data. Immunohistology showed a good concordance between transcript level and protein staining. The study indicates that gene expression patterns may be identified in bladder cancer by combining oligonucleotide arrays and cluster analysis. These patterns give new biological insight and may form a basis for the construction of molecular classifiers and for developing new therapy for bladder cancer.
A Comparison of CIELAB and CIECAM97s (1998)

The recently developed CIE color appearance model, CIECAM97s, provides an extension of the previously recommended CIE color spaces. This paper examines the new color appearance model by comparing it to CIELAB, one of the more widely used color spaces for digital color imaging. First, the perceptual attributes common to both spaces are compared and contrasted. Second, examining device gamuts in CIELAB and CIECAM97s further highlights differences in the spaces. Lastly, the trends in the color differences for the two color spaces are assessed. The focus of this paper is to highlight differences using simple numeric calculations.
Advances in the synthesis and application of nanoparticles for drug delivery (2015)

The continuous development of drug delivery systems (DDSs) has been extensively researched by the need to maximize therapeutic efficacy while minimizing undesirable side effects. Nanoparticle technology was recently shown to hold great promise for drug delivery applications in nanomedicine due to its beneficial properties, such as better encapsulation, bioavailability, control release, and lower toxic effect. Despite the great progress in nanomedicine, there remain many limitations for clinical application. To overcome these limitations, advanced nanoparticles for drug delivery have been developed to enable the spatially and temporally controlled release of drugs in response to specific stimuli at disease sites. Furthermore, the controlled self-assembly of organic and inorganic materials may enable their use in theranostic applications. This review presents an overview of a recent advanced nanoparticulate system that can be used as a potential drug delivery carrier and focuses on the potential applications of nanoparticles in various biomedical fields for human health care.

The historical background to the evolution of fabrics for military uniforms is reviewed together with some of the dyeing and finishing problems met. Changes from subjective to objective specification requirements following developments in test methods; from direct to indirect acceptance following developments in quality assurance procedures and in procurement are commented upon. Outstanding problems are discussed and recommendations made.
Influence of intracellular nucleotide and nucleotide sugar contents on recombinant interferon‐γ glycosylation during batch and fed‐batch cultures of CHO cells (2008)

Both the macroheterogeneity of recombinant human IFN-gamma produced by CHO cells and intracellular levels of nucleotides and sugar nucleotides, have been characterized during batch and fed-batch cultures carried out in different media. Whereas PF-BDM medium was capable to maintain a high percentage of the doubly- glycosylated glycoforms all over the process, mono-glycosylated and non-glycosylated forms increased during the batch culture using SF-RPMI medium. Intracellular level of UTP was higher in PF-BDM all over the batch culture compared to the SF-RPMI process. UDP-Gal accumulated only during the culture performed in PF-BDM medium, probably as a consequence of the reduced UDP-Glc synthesis flux in SF-RPMI medium. When the recombinant CHO cells were cultivated in fed-batch mode, the UTP level remained at a relatively high value in serum-containing RPMI and its titer increased during the fed-phase indicating an excess of biosynthesis. Besides, an accumulation of UDP-Gal occurred as well. Those results all together indicate that UTP and UDP-Glc syntheses in CHO cells cultivated in SF-RPMI medium in batch process, could be limiting during the glycosylation processes of the recombinant IFN-gamma. At last, the determination of the energetic status of the cells over the three studied processes suggested that a relationship between the adenylate energy charge and the glycosylation macroheterogeneity of the recombinant IFN-gamma may exist.
SELF: A High Performance and Bandwidth Efficient Approach to Exploiting Die-Stacked DRAM as Part of Memory (2017)

Die-stacked DRAM (a.k.a., on-chip DRAM) provides much higher bandwidth and lower latency than off-chip DRAM. It is a promising technology to break the "memory wall". Die-stacked DRAM can be used either as a cache (i.e., DRAM cache) or as a part of memory (PoM). A DRAM cache design would suffer from more page faults than a PoM design as the DRAM cache cannot contribute towards capacity of main memory. At the same time, obtaining high performance requires PoM systems to swap requested data to the die-stacked DRAM. Existing PoM designs fall into two categories – line-based and page-based. The former ensures low off-chip bandwidth utilization but suffers from a low hit ratio of on-chip memory due to limited temporal locality. In contrast, page-based designs achieve a high hit ratio of on-chip memory albeit at the cost of moving large amounts of data between on-chip and off-chip memories, leading to increased off-chip bandwidth utilization and significant system performance degradation.To achieve a similar high hit ratio of on-chip memory as page-based designs, and eliminate excessive off-chip traffic involved, we propose SELF, a high performance and bandwidth efficient approach. The key idea is to SElectively swap Lines in a requested page that are likely to be accessed according to page Footprint, instead of blindly swapping an entire page. In doing so, SELF allows incoming requests to be serviced from the on-chip memory as much as possible, while avoiding swapping unused lines to reduce memory bandwidth consumption. We evaluate a memory system which consists of 4GB on-chip DRAM and 12GB off-chip DRAM. Compared to a baseline system that has the same total capacity of 16GB off-chip DRAM, SELF improves the performance in terms of instructions per cycle by 26.9%, and reduces the energy consumption per memory access by 47.9% on average. In contrast, state-of-the-art line-based and page-based PoM designs can only improve the performance by 9.5% and 9.9%, respectively, against the same baseline system.

Moreover, the proposed deposition method is a powerful tool for material research to explore multicomponent oxide insulators and semiconductors.
GPS Antenna Design Characteristics for High‐Precision Applications (1989)

Antenna characteristics required for geodetic and subcentimeter accuracy GPS (Global Positioning System) applications are discussed, including the types of measurements needed for precise antenna calibration. The antenna phase characteristics over the upper hemispherical coverage region, which are of greatest importance in precise applications, are described in terms of a best‐fit (least mean square sense) sphere with associated residuals that may then be used for very precise correction of direct GPS carrier phase measurements. A criterion of ±5° phase ripple (maximum) and overall 5° rms deviation from the best‐fit sphere is presented for acceptable high‐accuracy performance. Measured phase responses are presented for two representative commercial GPS antennas; a quadrifilar helix (volute) at L1 frequency and a microstrip patch at L1 and L2 frequencies. Theoretical results obtained from analytic models are presented to identify the major factors that affect precise GPS antenna performance, including the electrical feed network balance, the use of ground planes, and signal multipath.
Measurement Results of an Affordable Hybrid Phased Array Using a Radant Lens (2000)

Abstract : An affordable phased array for a ship self-defense experimental engagement radar is described. The array used a hybrid approach by combining a slotted waveguide array with phase shifters at each column to provide scanning in the azimuth plane and a Radant lens placed in front of the slotted array to provide independent scanning in the elevation plane. The approach avoids using a phase shifter or a T/R module behind each radiating element and simplifies beam steering using row-column controls which reduce the phased array cost. The production cost of the proposed array is estimated to be less than one-third the cost of a similar sized array using a phase shifter or T/R module behind each radiating element. Recently, a 4' x 8' Radant lens was procured from Radant Technologies, Inc. and placed in front of the existing (modified AN/TPQ-36) phased array. This paper reports on the results of this hybrid array.

Spectrophone measurements of the absorption of visible light by aerosols in the atmosphere (1977)

Simultaneous in situ measurements of the absorption and scattering by aerosols were made in ambient room air and in air with large amounts of added aerosols, such as cigarette smoke. For room aerosols, the extinction contribution due to absorption was typically one half that from scattering. The absorption measurements were made with an acoustically resonant spectrophone powered with a 0.5-W argon laser.
Size Effects of PVP−Pd Nanoparticles on the Catalytic Suzuki Reactions in Aqueous Solution (2002)

A series of poly(N-vinyl-2-pyrrolidone) (PVP)-stabilized Pd nanoparticles with varying particle size are prepared by using the stepwise growth reaction. The effect of Pd particle size on the Suzuki reaction between phenylboronic acid and iodobenzene is investigated by the use of four Pd catalysts with mean particle sizes of 3.0, 3.9, 5.2, and 6.6 nm, respectively. The catalytic activity of the Pd nanoparticles expressed in terms of the initial turnover frequency (moles of the biphenyl product per mole of total surface Pd atoms per min) is found to be in the order of Pd (3.9 nm) > Pd (3.0 nm) ≈ Pd (5.2 nm) > Pd (6.6 nm), indicating that surface Pd atoms do not all have the same reactivity in this reaction. The general trend of increased catalytic activity with the decrease in the particle size suggests that the low-coordination number vertex and edge atoms on the particle surface are active sites for the Suzuki reaction. The lower catalytic activity for the smallest Pd nanoparticles might be due to stronger adsorption of the reaction intermediates on the particle surface, in which the strongly adsorbed species act as a poison to the reaction thereby decreasing the rate of the reaction.
