α <sub>1</sub> and α <sub>2</sub> Ca <sup>2+</sup> channel subunit expression in human neuronal and small cell carcinoma cells (1994)

Monoclonal antibodies that recognize skeletal muscle dihydropyridine-sensitive calcium channel subunits were used to identify similar proteins in neuronal and small cell carcinoma cell lines. alpha 1-related proteins were detected by FACS analysis on the surface of human neuroblastoma (IMR 32) and small cell carcinoma (DMS 273 and DMS 114) cell lines. alpha 1-like polypeptides from these cells were isolated and partially characterized. The polypeptides exhibit an M(r) similar to that of the L-type channel alpha 1 subunit and are recognized by two distinct anti-alpha 1 mAbs. The data provide biochemical evidence for structural similarities between the alpha 1 subunit of small cell carcinoma and neuronal cell lines. Similarly, an alpha 2-like protein was characterized from these cells. Because alpha 2 is a subunit shared by many subtypes of calcium channels, these data suggest that subunits other than the pore-forming alpha 1 subunit may play an important role in the etiology of Lambert-Eaton syndrome. We demonstrate directly that small cell carcinoma and a cell line derived from peripheral neurons share L-type calcium channel-related proteins and a protein common to many voltage-gated calcium channel subtypes. These data support a model that proposes that cross-reactivity of anti-tumor cell antibodies with presynaptic elements, possibly calcium channels, plays a role in the development of Lambert-Eaton syndrome.
Anisotropic spin-wave patterns generated by spin-torque nano-oscillators (2011)

Spin-wave excitations due to spin-momentum transfer in ferromagnetic thin films will enable new types of information processing and memory storage. Here, we show how arrays of spin-torque nano-oscillators (STNOs) can be used to create anisotropic spin-wave interference patterns, which can be used for information processing. We consider STNO arrays contacting a thin ferromagnetic film. Contacts to the film (including the STNOs themselves) can be used to detect the spin-waves and then, when coupled to a simple circuit, can create new excitation patterns. The propagating spin-wave patterns can be generated by pulsing transponders. Arrangements of transponders create resonant (reverberating) spin-wave activity-that may be the basis of polychronous wave computation of the arithmetic and Boolean functions as well as information storage
Ultra-short-term Distributed Photovoltaic Power Forecasting Based on Cloud Image Feature Extraction (2021)

Distributed renewable resources have the characteristics of scattered geographical location, different scale and violent power fluctuation. In order to make full use of the potential of distributed renewable resources, high requirements are put forward for prediction methods. This paper proposes a forecasting method for distributed photovoltaic power prediction. Firstly, this paper establishes a fixed square window with the sun as the center, processes the cloud information and creates an image with only the relationship between the gray and the position of cloud. Secondly, according to the historical data, the position and grayscale picture of the cloud cluster at the next moment are generated. In the third step, proposes the influence factor of cloud cluster to evaluate the influence of the cloud distribution and thickness on the surface illumination, then input it into the improved CNN network as an auxiliary parameter, combined with the current outer atmospheric tangent plane solar radiation to get the predicted illumination at the next time. Finally, outputs the predicted photovoltaic power value, which combine the predicted illumination, current real-time temperature with the efficiency of the inverter. The case study demonstrates that this method has strong adaptability and it is capable of forecasting ultra-short-term changes in photovoltaic power. The method can greatly reduce the amount of data to the prediction network and also accelerate the convergence speed while ensuring the predict accuracy.
Feedback control in a distributed scheduling architecture (2002)

Multiple-module, multistage packet switching systems are gaining popularity as a scalable solution to the ever increasing demand for the aggregate switching capacity. Due to additional contention points between the stages, such systems differ in their behavior from single module output buffered switches, which serve as a model for most of the advanced quality of service (QoS) scheduling algorithms. Recently, a distributed scheduling reference architecture has been proposed to extend the QoS provisioning framework to the practical multistage switches. While keeping all the per-flow state information in the port card, it aggregates the individual traffic flows into a few QoS based fabric channels and relies on the intelligent selective feedback to ensure that the QoS guarantees of the individual flows are met. In this paper we discuss a novel credit-based feedback mechanism that allows to aggregate multiple traffic components with diverse QoS requirements into the same downstream FIFO queue. We specifically apply it to merge the guaranteed-bandwidth (GB) and best-effort (BE) QoS channels of the distributed scheduling architecture into a single non-guaranteed-delay queue in the switch fabric. The mechanism allows to satisfy the bandwidth requirements of the GB traffic while maximizing the throughput of the BE traffic and distributes the available excess bandwidth between different types of traffic fairly. The presentation is supported by fluid stationary analysis and packet-level simulations.
Identification of <i>Bacillus</i> Spores by Matrix-Assisted Laser Desorption Ionization–Mass Spectrometry (1999)

Unique patterns of biomarkers were reproducibly characterized by matrix-assisted laser desorption ionization (MALDI)-mass spectrometry and were used to distinguish Bacillus species members from one another. Discrimination at the strain level was demonstrated for Bacillus cereus spores. Lipophilic biomarkers were invariant in Bacillus globigii spores produced in three different media and in B. globigii spores stored for more than 30 years. The sensitivity was less than 5,000 cells deposited for analysis. Protein biomarkers were also characterized by MALDI analysis by using spores treated briefly with corona plasma discharge. Protein biomarkers were readily desorbed following this treatment. The effect of corona plasma discharge on the spores was examined.
/sup 3/He-/sup 4/He refrigerator (1981)

/sup 3/He-/sup 4/He refrigerator is disclosed in which superfluid /sup 4/He is circulated by thermomechanical pumping device which is based on the fountain pump effect and which is constructed from several series-arranged fountain pumps.
Integration of a receiver front-end in multilayer ceramic integrated circuit (MCIC) technology (2002)

In the commercial wireless industry significant progress has been made in the integration and size reduction of frequency processing functions in semiconductor products, but the integration of frequency selective devices that require many passive components has lagged. Efforts are underway to integrate passive components into organic printed circuit boards but frequency selective devices, such as VCOs and filters, require higher quality (Q) components than the typical PCBs can deliver. Multilayer ceramic integrated circuits (MCIC), utilizing a low temperature co-fired ceramic materials systems, has proven that high a passive components can be integrated in this technology to form individual devices such as T/R switches and filters. While MCIC has made a dent in the size and weight reduction of wireless devices, its significant impact will occur when multiple functions are combined into the integrated circuit. The integration of a major portion of a wireless radio receiver front-end into a single MCIC unit has been demonstrated. This circuit incorporates a T/R switch with harmonic filter, two band reject filters, one bandpass filter, an impedance matching network, bias circuitry and a low noise amplifier. The package was 500 by 500 by 90 mils and had 44 embedded passive components and 11 components mounted on its top surface. The result of this integration was a doubling of component density over previous designs.
Millimix: Mixing in Small Batches (1999)

We present Millimix, a mix network that is highly efficient on small input batches. The construction is conceptually simple, and both robust and private in the face of collusion by any minority set of malicious players. Additionally, Millimix the feature of being publicly verifiable. In other words, the mixing operation yields a transcript that demonstrates correctness to a third party that the mix proceeded correctly.
Carbon disulfide reagent allows the characterization of nonpolar analytes by atmospheric pressure chemical ionization mass spectrometry (2011)

While atmospheric pressure ionization methodologies have revolutionized the mass spectrometric analysis of nonvolatile analytes, limitations native to the chemistry of these methodologies hinder or entirely inhibit the analysis of certain analytes, specifically, many nonpolar compounds. Examination of various analytes, including asphaltene and lignin model compounds as well as saturated hydrocarbons, demonstrates that atmospheric pressure chemical ionization (APCI) using CS(2) as the reagent produces an abundant and stable molecular ion (M(+•)) for all model compounds studied, with the exception of completely saturated aliphatic hydrocarbons and the two amino acids tested, arginine and phenylalanine. This reagent substantially broadens the applicability of mass spectrometry to nonvolatile nonpolar analytes and also facilitates the examination of radical cation chemistry by mass spectrometry.
Why so little progress in therapeutic thrombolysis? The current state of the art and prospects for improvement (2015)

Thrombosis is a major contributor to disability and mortality worldwide and is estimated to be the cause of one in four deaths [1]. It is the pathology responsible for triggering acute myocardial infarction (AMI) and ischemic stroke, and is the primary cause of venous thromboembolism. The pathogenesis has been well-studied starting with Virchow more than 150 years ago [2], and its prevention by anti-thrombotic drugs has made much progress, culminating most recently in the approval of new oral anticoagulants which are specific inhibitors of thrombin or factor Xa.

By contrast, treatment by thrombolysis, the only pharmacological means available, has remained at a near standstill since Genentech first applied for FDA approval of tissue plasminogen activator (tPA) in 1983. A replacement for streptokinase (SK) had been long-sought, but after early successes in AMI, tPA use has since been on the decline.

Instead, percutaneous coronary intervention (PCI) has become the treatment of choice in AMI, despite its technical, time-consuming, and costly demands. Pre-treatment with tPA to hasten coronary reperfusion, so-called facilitated PCI, was found to increase PCI complications including intracranial hemorrhage (ICH) making the two incompatible [3]. In ischemic stroke, tPA has been estimated to be used in only 2–5 % of patients over-all [4], and in pulmonary embolism, bleeding and stroke complications limited its use to the minority of patients with hemodynamic decompensation [5].

The recent trend in stroke has also begun to favor the use of endovascular devices with three major trials in ischemic stroke published in the first 2 months of 2015 in the NEJM [6–8]. In this same period, a clinical trial of catheter-directed ultrasound was also published which showed a significant acceleration of the thrombolysis rate by this method [9].

These device reperfusion techniques require bringing the patient to a qualified facility which inevitably consumes precious time for conditions in which “minutes are myocardium or neurons.” An optimal treatment for these time-sensitive conditions can only be one that can be brought to the patient and is easily and safely administered. The resort to alternative methods is a reflection on the inadequacy of current thrombolysis, a problem that was foretold by the results with tPA in major clinical trials.
A new video watermarking protocol (2003)

This paper overviews the problems with temporal synchronization in video watermarking and describes a new approach for efficient synchronization and resynchronization. A complete version of the new method has been presented.
Bamboo fiber‐reinforced polypropylene composites: Crystallization and interfacial morphology (1997)

Bamboo fiber-reinforced polypropylene (PP) composites were prepared. PP and two maleated polypropylenes (s-MAPP and m-MAPP) were used as matrices. Crystallization and interfacial morphology were studied by using differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD), and optical microscopy. It has been shown that the addition of bamboo fiber to any of the three polymers causes an increase in the overall crystallization rate. A considerable amount of β-form crystallinity was produced in the PP, s-MAPP, and m-MAPP by mixing with bamboo fiber; and all the bamboo fiber-filled samples contain both the α- and the β-forms. The relative amount of the β-form in the samples was calculated from WAXD data by the K value. There is no β-form observed in the pure PP, s-MAPP, and m-MAPP. Bamboo fiber acted as both a reinforcement and a β-nucleator. The nucleation density of both s-MAPP and m-MAPP at the fiber surface is remarkably higher than that of PP because an improved interfacial adhesion is reached in the case of s-MAPP and m-MAPP as matrices. The transcrystalline growth of s-MAPP and m-MAPP on the bamboo fiber surface was observed under optical microscope with crossed polars. © 1997 John Wiley & Sons, Inc.

Fourier-based approach to interpolation in single-slice helical computed tomography (2001)

It has recently been shown that longitudinal aliasing can be a significant and detrimental presence in reconstructed single-slice helical computed tomography (CT) volumes. This aliasing arises because the directly measured data in helical CT are generally undersampled by a factor of at least 2 in the longitudinal direction and because the exploitation of the redundancy of fanbeam data acquired over 360 degrees to generate additional longitudinal samples does not automatically eliminate the aliasing. In this paper we demonstrate that for pitches near 1 or lower, the redundant fanbeam data, when used properly, can provide sufficient information to satisfy a generalized sampling theorem and thus to eliminate aliasing. We develop and evaluate a Fourier-based algorithm, called 180FT, that accomplishes this. As background we present a second Fourier-based approach, called 360FT, that makes use only of the directly measured data. Both Fourier-based approaches exploit the fast Fourier transform and the Fourier shift theorem to generate from the helical projection data a set of fanbeam sinograms corresponding to equispaced transverse slices. Slice-by-slice reconstruction is then performed by use of two-dimensional fanbeam algorithms. The proposed approaches are compared to their counterparts based on the use of linear interpolation-the 360LI and 180LI approaches. The aliasing suppression property of the 180FT approach is a clear advantage of the approach and represents a step toward the desirable goal of achieving uniform longitudinal resolution properties in reconstructed helical CT volumes.
Tunable orbital angular momentum mode filter based on optical geometric transformation (2014)

We present a tunable mode filter for spatially multiplexed laser beams carrying orbital angular momentum (OAM). The filter comprises an optical geometric transformation-based OAM mode sorter and a spatial light modulator (SLM). The programmable SLM can selectively control the passing/blocking of each input OAM beam. We experimentally demonstrate tunable filtering of one or multiple OAM modes from four multiplexed input OAM modes with vortex charge of ℓ=-9, -4, +4, and +9. The measured output power suppression ratio of the propagated modes to the blocked modes exceeds 14.5 dB.
Congenital muscular dystrophy with merosin deficiency. (1994)

Congenital muscular dystrophy is one of the most frequent and severe childhood muscular dystrophies. Several forms of this disease have been described. The form associated with marked central nervous system disturbances, frequent in Japan, is known as Fukuyama congenital muscular dystrophy and was recently linked to chromosome 9. The most frequent form observed in occidental countries appears to be clinically characterized by exclusive involvement of skeletal muscle, and has been identified by clinico-pathological features which are often fallacious. A predominant histopathological feature is the marked increase in endomysial collagen tissue. We investigate whether laminin, a major component of the extracellular matrix, which is linked to the subsarcolemmal cytoskeleton by a large oligomeric complex of dystrophin-associated glycoproteins, could be involved in this form. We observed a specific absence of merosin, the laminin M chain, in 13 patients affected by classical non-Japanese form of congenital muscular dystrophy. This result allows the precise identification of a particular form of congenital muscular dystrophy and gives a clue to understanding its molecular pathogenesis.
SNR improvement for multiinjection time‐resolved high‐resolution CE‐MRA of the peripheral vasculature (2003)

Peripheral MR angiography (MRA) should ideally provide images over a large field of view with high spatial resolution and adequate temporal resolution to accommodate differences in regional filling times. Image subtraction is usually used to remove background signals. In examination protocols involving multiple injections at multiple sites, previously injected contrast present in the mask image provides a substantial decrease in the subtraction image signal. Bolus chase methods avoid this problem but provide limited time for acquisition of high-resolution images at each station. We present here a technique applied to peripheral angiography that provides high spatial and temporal resolution while maintaining high SNR in multiple injection examinations. Undersampled projection imaging was used to increase spatial resolution relative to a previously reported technique using a Cartesian acquisition technique. Late acquisition of high spatial frequencies and temporal matched-filtering were used to increase spatial resolution and SNR, respectively. Temporal correlation analysis was applied to permit multistation examinations without mask subtraction, thus providing an additional gain in SNR relative to multistation subtraction methods. Quantitative analysis is provided to evaluate the signal and noise behavior in the matched-filtering process due to multiinjection and mask subtraction.
Efficient and thread-safe objects for dynamically-typed languages (2016)

We are in the multi-core era. Dynamically-typed languages are in widespread use, but their support for multithreading still lags behind. One of the reasons is that the sophisticated techniques they use to efficiently represent their dynamic object models are often unsafe in multithreaded environments.
Language modeling for voice search: A machine translation approach (2008)

This paper presents a novel approach to language modeling for voice search based on the idea and method of statistical machine translation. We propose an n-gram based translation model that can be used for listing-to-query translation. We then leverage the query forms translated from listings to improve language modeling. The translation model is trained in an unsupervised manner using a set of transcribed voice search queries. Experiments show that the translation approach yielded drastic perplexity reductions compared with a baseline language model where no translation is applied.
Process for producing low sulfur coke. [8 claims] (1977)

A low-sulfur coke product is obtained in an integrated fluid coking and gasification process in which an oxygen-containing gas is introduced into the upper portion of the gasification zone and steam is introduced into the lower portion of the gasification zone. The desired degree of coke desulfurization is controlled by controlling the thickness of the gasifier coke layer on the gaseous reactor leaving solids per pass. 8 claims, 2 figures.
Use of Antibodies in Lymphocyte Secretions for Detection of Subclinical Tuberculosis Infection in Asymptomatic Contacts (2004)

We have previously demonstrated that Mycobacterium bovis BCG-specific immunoglobulin G antibodies in lymphocyte secretions (ALS) can be employed as a marker for active tuberculosis (TB). We aimed to determine whether the ALS method allows detection of subclinical TB infection in asymptomatic individuals. A prospective study of family contacts (FCs) of patients with active TB and healthy controls was performed. Thirteen of 42 FCs had high ALS responses, including 6 FCs who subsequently developed active TB. No correlation was observed between the tuberculin skin test and the ALS responses in the FCs (r = 0.1, P = 0.23). Among patients with active TB, BCG-specific ALS responses steadily declined from the time of diagnosis through 6 months following antimycobacterial chemotherapy (P = 0.001). The ALS assay enabled detection of infection in exposed symptom-free contacts, who are at greater risk for developing active TB. The method may also allow discrimination between effective treatment of active infection and suboptimal response to therapy.
Multichannel Dynamic-Range Compression Using Digital Frequency Warping (2005)

A multichannel dynamic-range compressor system using digital frequency warping is described. A frequency-warped filter is realized by replacing the filter unit delays with all-pass filters. The appropriate design of the frequency warping gives a nonuniform frequency representation very close to the auditory Bark scale. The warped compressor is shown to have substantially reduced group delay in comparison with a conventional design having comparable frequency resolution. The warped compressor, however, has more delay at low than at high frequencies, which can lead to perceptible changes in the signal. The detection threshold for the compressor group delay was determined as a function of the number of all-pass filter sections in cascade needed for a detectible change in signal quality. The test signals included clicks, vowels, and speech, and results are presented for both normal-hearing and hearing-impaired subjects. Thresholds for clicks are lower than thresholds for vowels, and hearing-impaired subjects have higher thresholds than normal-hearing listeners. A frequency-warped compressor using a cascade of 31 all-pass filter sections offers a combination of low overall delay, good frequency resolution, and imperceptible frequency-dependent delay effects for most listening conditions.
Antenna beamwidth control using parasitic subarrays (2002)

A new and effective technique of controlling the azimuth pattern of a singly or dually polarized linear antenna array is presented. It is shown that the use of parasitic elements allows us to control the azimuth beamwidth over a wide range. It is noted that this technique could be applied to other linear arrays, using other radiating elements. The analysis of coupling between fed and parasitic elements is specific to the type of element that is used, but the overall approach would still be useful.
