Local-Area MultiProcessor: the scalable coherent interface (1994)

There is rapidly increasing demand for very high performance shared access to distributed data, for multiprocessors, networked workstation clusters, distributed databases, industrial data acquisition and control systems, etc. The objective is to satisfy this demand at the lowest long-term cost. This paper first considers the general properties that an appropriate system architecture should have. A new architectural model, Local-Area Multiprocessor, is introduced. These properties are then considered in more detail, and practical design decisions are made, illustrated by the evolution of the ANSEIEEE standard Scalable Coherent Interface (SCI) as it addressed these issues. Finally, the current status of the various SCI follow-on and support projects is reported.
Development of a Spray System for an Unmanned Aerial Vehicle Platform (2009)

Application of crop production and protection materials is a crucial component in the high productivity of American agriculture. Agricultural chemical application is frequently needed at specific times and locations for accurate site-specific management of crop pests. Piloted agricultural aircraft are typically used to treat large, unobstructed, continuous acreage crops and are not as efficient when working over small or obstructed plots. An Unmanned Aerial Vehicle (UAV), which can be remotely controlled or fly autonomously based on pre-programmed flight plans, may be used to make timely and efficient applications over these small area plots. This research developed a low volume spray system for use on a fully autonomous UAV to apply crop protection products on specified crop areas. This article discusses the development of the spray system and its integration with the flight control system of a fully autonomous, unmanned vertical take-off and landing helicopter. Sprayer actuation can be triggered by preset positional coordinates as monitored by the equipped Global Positioning System (GPS). The developed spray system has the potential to provide accurate, site-specific crop management when coupled with UAV systems. It also has great potential for vector control in the areas that are not easily accessible by personnel or equipment.
Scopes in Discourse (1996)

In this paper we show that the dynamic interpretation techniques of Janssen (assignment modalities), Groenendijk and Stokhof (dynamic binding), and Hendriks (exibly scoping rules) enable a rigorous formulation of the semantics of intersentential anaphoric relationships, as well as of telescoping and periscoping phenomena in natural language. Keywords: Natural Language Semantics, Dynamic Interpretation, Flexible Type Theory, Scope and Binding. 1 Introduction In this paper we want to show that the potential of techniques of dynamic interpretation as developed by Janssen, Groenendijk and Stokhof, and Hendriks in the second half of the eighties has not yet been fully recognized. Not only do these techniques allow a rigorous formulation of the semantics of anaphoric relationships across sentential or clausal borders (including `donkey-anaphora&apos;), but they are also the right ones for formulating the semantics of what Craige Roberts has dubbed `telescoping&apos; and that of what is called `peri...
Genetical and Biochemical Studies of Glucosephosphate Isomerase Deficient Mutants in Saccharomyces cerevisiae (1978)

A number of glucose-negative mutants of Saccharomyces cerevisiae were isolated and shown to contain very low activities of glucosephosphate isomerase. Mutants almost totally lacking this enzyme (less than 1% of wild-type activity) grew on fructose if provided with a small quantity of glucose. Larger amounts of glucose led to the accumulation of glucose 6-phosphate and growth inhibition. These mutants did not grow on galactose. Other mutants with low enzyme activities (about 1% of wild type) grew on fructose alone and also on galactose. The mutant characters were determined in both cases by single gene mutations which were mapped on chromosome II and, presumably, identify a structural gene locus for the enzyme.
MiR-223-3p targeting SEPT6 promotes the biological behavior of prostate cancer (2014)

MicroRNAs (miRNAs) present frequently altered expression in urologic cancers including prostate, bladder, and kidney cancer. The altered expression of miR-223 has been reported in cancers and other diseases in recent researches. MiR-223 is up-regulated in systemic lupus erythematosus and rheumatoid arthritis. In neoplastic diseases, miR-223 is proved to be up-expressed in plasma or serum and cancer tissues compared with normal tissues in pancreatic cancer, gastric cancer, et al. However, whether altered expression of miR-223 is associated with prostate cancer (PCa) and what it is potential functions in PCa remained unveiled. In this study, we firstly found miR-223-3p were up-regulated in prostate cancer tissues and then we study functional role of miR-223-3p in PCa using DU145, PC3 and LNCaP cell lines. Our data suggested that miR-223-3p might target gene SEPT6 and promoted the biological behavior of prostate cancer. Notably, we found increasing SEPT6 expression might reverse the biological activity induced by miR-223-3p, which might be a potential therapeutic target for PCa.
Interleukin-4 Promotes the Development of Tryptase and Chymase Double-Positive Human Mast Cells Accompanied by Cell Maturation (1998)

Human cultured mast cells (HCMCs) grown from cord blood mononuclear cells in the presence of stem cell factor (SCF) and interleukin-6 (IL-6) expressed tryptase but no or low chymase in their cytoplasm. The addition of IL-4 to these cells strikingly increased chymase expression. Consequently, the activity of chymase was significantly higher in IL-4–treated mast cells than that in IL-4–nontreated mast cells, whereas the activity of tryptase and histamine content were comparable in both cells. Electron microscopic immunocytochemistry also showed that secretary granules containing chymase increased in IL-4–treated mast cells. Interestingly, the IL-4–induced increase of chymase expression in HCMCs was accompanied by morphological maturation of the cells. Cytoplasmic projections were few in IL-4–nontreated HCMCs, and a small number of secretary granules were observed, most of which were empty or partially filled with discrete scrolls with rough particles showing immaturity. In contrast, IL-4–treated HCMCs had extremely abundant cytoplasmic projections and had many secretary granules filled with electron-dense crystal materials. Taken together, immature HCMCs grown only with SCF and IL-6 expressed tryptase with no or a low amount of chymase, and addition of IL-4 promoted cell maturation together with the expression of both tryptase and a high amount of chymase. Our findings will raise a possibility of a linear pathway of human mast cell development from tryptase single positive mast cells into tryptase and chymase double positive mast cells as the cells mature and will suggest that this maturation process is promoted by IL-4.
Accurate dense optical flow estimation using adaptive structure tensors and a parametric model (2003)

An accurate optical flow estimation algorithm is proposed in this paper. By combining the three-dimensional (3D) structure tensor with a parametric flow model, the optical flow estimation problem is converted to a generalized eigenvalue problem. The optical flow can be accurately estimated from the generalized eigenvectors. The confidence measure derived from the generalized eigenvalues is used to adaptively adjust the coherent motion region to further improve the accuracy. Experiments using both synthetic sequences with ground truth and real sequences illustrate our method. Comparisons with classical and recently published methods are also given to demonstrate the accuracy of our algorithm.
Markov Random Fields and Images (1998)

At the intersection of statistical physics and probability theory, Markov random elds and Gibbs distributions have emerged in the early eighties as powerful tools for modeling images and coping with high-dimensional inverse problems from lowlevel vision. Since then, they have been used in many studies from the image processing and computer vision community. Abrief and simple introduction to the basics of the domain is proposed. 1. Introduction and
Crosslinked Cements Solve Lost Circulation Problems (2004)

Abstract A novel alternative has been developed to solve severe lost circulation problems. Cross linked cements (CC) can help to seal temporarily or indefinitely critical intervals where drilling and cementing operations are very difficult to be successfully accomplished due to severe lost circulation. The system can be designed in two versions, the first is a Magnesia cross linked cement (MCC), up to 98% soluble, especially designed to be used in pay zones, the second, a low cost alternative, is a regular cross linked cement(RCC) which is 73% soluble and is appropriate for sealing non- productive intervals. Positive results have been observed in field applications of both systems.
Tangible programming and informal science learning (2008)

In this paper we describe the design and initial evaluation of a tangible computer programming exhibit for children on display at the Boston Museum of Science. We also discuss five design considerations for tangible interfaces in science museums that guided our development and evaluation. In doing so, we propose the notion of passive tangible interfaces. Passive tangibles serve as a way to address practical issues involving tangible interaction in public settings and as a design strategy to promote reflective thinking. Results from our evaluation indicate that passive tangibles can preserve many of the benefits of tangible interaction for informal science learning while remaining cost-effective and reliable.
Scattering of electromagnetic waves by a slowly rotating rectangular metal plate (1979)

The amplitude modulation waveforms of linearly polarized electromagnetic waves due to the scattering by slowly rotating metal plates are investigated theoretically and experimentally. The nature of the modulation waveform depends on the orientation and dimensions of the object, its rotation speed, and very strongly on the incident and receiving (or scattering) directions. For a rectangular metal plate rotating in its own plane, the modulation is independent of time in the specular and forward directions. Near the specular and forward directions the modulation waveform is a sinusoidal function having a frequency equal to twice the rotation frequency of the plate. Further away from these directions, the waveform is a sinc-pulse type repeating at twice the rotation frequency. Similar results are also discussed for a rotating skewed metal plate. The observed waveforms are found to be in good agreement with theoretical results.
Selective and differential medium for the primary isolation of members of the Proteeae (1986)

A new differential and selective medium for the isolation of members of the Proteeae, PIM (Proteeae isolation medium) agar, was developed and evaluated. The medium relies on the ability of all members of the Proteeae (with the exception of a very few Morganella morganii strains) to produce a dark brown pigment in medium containing DL-tryptophan. An additional differential property, tyrosine degradation, was also demonstrated by the medium. Members of the Proteeae appeared as dark brown colonies with a halo of clearing of fine tyrosine crystals when cultured on PIM agar. Occasional strains of Citrobacter sp. and Pseudomonas aeruginosa may degrade tyrosine, but none has the ability to produce dark brown pigmentation on PIM agar. Quantitative recovery studies showed that the addition of 5 mg of clindamycin per liter suppressed gram-positive bacteria without inhibiting any strains of the Proteeae. The addition of 100 mg of colistin per liter made the medium highly selective for strains of the Proteeae, but approximately 10% of the strains were not isolated, thus making this formulation unsuitable for general surveys of the occurrence of members of the Proteeae. PIM agar should aid the investigation of episodes of cross infection caused by members of the Proteeae and the isolation of the new species of the Proteeae recently described.
Eutectic bump evaluation with various passivation and polyimide structures [flip chip interconnects] (2003)

A set of critical parameters, namely passivation opening and polyimide pull-back/push-forward (i.e. covering the passivation edge and extending on to the aluminum pad) have been studied. The test vehicle used for this analysis was an F35S daisy chain on a laminated substrate. In this study, the packages were subjected to environmental stress test and bumped bare dice subjected to autoclave testing. The major failure modes seen were solder ingression into the incomplete underfill around the bumps, and cracks in the passivation layer and substrates. The investigation revealed that the bond pad designs with larger passivation opening and polyimide push-forward yielded a more reliable structure. The simulation study showed that there is a 600% reduction in the bump formation and reflow induced stress on the structure where the polyimide extending on to the aluminum compared to no polyimide on to the passivation.

Capacitive Micromachined Ultrasonic Transducers for Non-destructive Testing Applications (2014)

Ultrasound is a popular technique for industrial non-destructive testing (NDT) applications. By sending ultrasonic waves into an object and observing the amplitude and the delay of the reflected or transmitted waves, one can characterize the material, measure the thickness of the object, and detect discontinuities (flaws) as well as the size, location, and orientation of the defects in the object. Traditionally, ultrasonic transducers for NDT are made with piezoelectric crystals. Meanwhile, another class of ultrasonic transducers known as capacitive micromachined ultrasonic transducers (CMUTs) have become popular in medical ultrasound research because of their large bandwidths and other attributes that allow them to be integrated into the tip of a catheter. However, CMUTs have not been widely adopted in ultrasonic NDT applications.\n\nIn this thesis, three important CMUTs characteristics that could potentially make them attractive for NDT applications are introduced and demonstrated. First, CMUTs can be beneficial to NDT because the fabrication techniques of CMUTs can easily be used to implement high-frequency, high-density phased arrays, which are essential for high resolution scanning. Surface scanning using a 2-D row-column addressed CMUT array was demonstrated. Secondly, CMUTs can be integrated with supporting microelectronic circuits, thus one can implement a highly integrated transducer system, which can be useful in structural health monitoring NDT applications. Front-end microelectronic circuits that include a transmit pulser and a receive amplifier were designed, tested, and characterized. Thirdly, CMUTs are suitable for air-coupled applications because of their low acoustic impedance at resonance. Air-coupled CMUTs fabricated in a standard RF-MEMS process were characterized and tested.\n\nThis thesis concludes with an analysis of the potential usefulness of CMUTs for ultrasonic NDT. While many ultrasonic NDT applications are better off being performed using conventional piezoelectric transducers, CMUTs can and should be used in certain NDT applications that can take advantage of the beneficial characteristics of this exciting transducer technology.
Caffeine as a Lipolytic Food Component Increases Endurance Performance in Rats and Athletes. (2001)

Caffeine is one of the famous ergogenic aids in the athletic field. Caffeine has been known to stimulate lipolysis that spares stored glycogen utilization during moderate intensity exercise. Therefore, we investigated the effects of caffeine ingestion on exercise performance in rats and athletes. Rats were administered the caffeine (6 mg/kg) 1 h prior to the exercise then were run on a treadmill at a speed of 20 m/min. They were decapitated at 0 min, 30 min, 60 min of exercise, and exhausted time point. Human subjects ingested the caffeine (5 mg/kg) 1 h prior to the exercise. They exercised on a cycle ergometer at 60% of their VO2max for 45 min, and then the exercise intensity was increased to 80% of their VO2max until exhaustion. Blood and breathing gas samples were collected and calculated every 10 min during exercise. Respiratory exchange ratio of the caffeine trial was significantly lower than that of the placebo trial in the athletes' study (p<0.05). Blood free fatty acid (FFA) levels in studies of both rats and athletes were increased by caffeine ingestion during exercise (p<0.05). Blood lactate levels were also increased during exercise in both rats and athletes (p<0.05). Increased FFA and glycerol concentrations reduced glycogen utilization during exercise compared with placebo group in rats. In addition, endurance time to exhaustion was significantly increased by the caffeine ingestion in both rats and athletes (p<0.05). These results suggest that the caffeine ingestion enhanced endurance performance resulting from spare stored glycogen with increasing lipolysis from adipose tissues and fat oxidation during exercise both in rats and in athletes.
Hot Electrons Do the Impossible: Plasmon-Induced Dissociation of H<sub>2</sub> on Au (2012)

Heterogeneous catalysis is of paramount importance in chemistry and energy applications. Catalysts that couple light energy into chemical reactions in a directed, orbital-specific manner would greatly reduce the energy input requirements of chemical transformations, revolutionizing catalysis-driven chemistry. Here we report the room temperature dissociation of H(2) on gold nanoparticles using visible light. Surface plasmons excited in the Au nanoparticle decay into hot electrons with energies between the vacuum level and the work function of the metal. In this transient state, hot electrons can transfer into a Feshbach resonance of an H(2) molecule adsorbed on the Au nanoparticle surface, triggering dissociation. We probe this process by detecting the formation of HD molecules from the dissociations of H(2) and D(2) and investigate the effect of Au nanoparticle size and wavelength of incident light on the rate of HD formation. This work opens a new pathway for controlling chemical reactions on metallic catalysts.
Inhaled natural human interferon alpha induces bronchospastic reactions in asthmatics. (1992)

There is a relationship between viral infection and aggravation of bronchial asthma symptoms. Viruses belong to the strongest and fast acting inducers of interferon (IFN), which, in turn, may enhance histamine release from effector cells. We have administered IFN intrabronchially to 49 patients suffering from bronchial asthma. The impairment of lung ventilation with significant decrease of forced expiratory volume in one second (FEV1) have been observed in majority of the patients who inhaled crude or purified IFN preparations.
Method for Studying Sputtered Particles by Emission Spectroscopy (1966)

An f/6.8 scanning spectrometer with a photomultiplier output was used to monitor the presence of particles sputtered from a target surface by ion bombardment. The ion source was a conventional duoplasmatron providing a high density, high energy ion beam. The density of sputtered particles available for analysis was of the order of 108 cm−3. A fraction of these particles was electronically excited by a high density, low energy electron beam, and the emission spectra characteristic of the target material were recorded with either an electrometer or a phase sensitive detector. Some intense atomic copper lines were easily observed when a Cu target was bombarded with 5000 eV Ar+ ions. The intensities of these lines have been analyzed to obtain the sputtering yield and some relative excitation functions for copper. A comparison between the conventional mass spectrometric technique and the present scheme is presented.
