Matching Conflicts: Functional Validation of Agents (1999)

In most working and proposed multiagent systems, the problems of identifying and locating agents that can provide specific services are of major concern. A broker or matchmaker service is often proposed as a solution. These systems use keywords drawn from application domain ontologies to specify agent services, usually framed within some sort of knowledge representation language. However, we believe that keywords and ontologies cannot be defined and interpreted precisely enough to make brokering or matchmaking among agents sufficiently robust in a truly distributed, heterogeneous, multiagent computing environment. This creates matching conflicts between a client agent&amp;apos;s requested functionality and a service agent&amp;apos;s actual functionality. We propose a new form of interagent communication, called functional validation, specifically designed to solve such matching conflicts. In this paper we introduce the functional validation concept, analyze the possible situations that...
Current path optimized structure for high drain current density and high gate-turn-on voltage enhancement mode heterostructure field effect transistors (2002)

We developed a new type of enhancement-mode (E-mode) heterostructure field effect transistors (FETs) which provide single-voltage operation of power amplifiers in portable phone handsets. Gate leakage current paths were optimized, and a high gate-turn-on voltage and a high drain current density were obtained at the same time. This allows a 50% increase of the drain current by shortening the gate-to-source length without increasing the gate leakage current. We applied this technique to completely E-mode FETs (Vth>0.3 V). A power added efficiency as high as 70.6% has been achieved for an output power of 33 dBm under a Vds of 3.5 V at 850 MHz.

How does speaking another language reduce the risk of dementia? (2014)

Recently the question of whether or not bilingualism may protect against the development of Alzheimer's disease (AD) has become a topic of great interest. Previous studies suggest that being bilingual slows the decline in executive control associated with the aging process. Spurred by these positive findings in normal subjects, investigators have tried to determine if being bilingual may be associated with delayed onset of AD. A number of studies collectively suggest that being bilingual may lead to a delay in the diagnosis of AD by as much as 5 years, even when taking into account confounders. Although a recent landmark study provides physical evidence confirming this advantage in AD patients, further work needs to be done to clarify its' neuroanatomical basis.
The rRNA m6A methyltransferase METTL5 is involved in pluripotency and developmental programs (2020)

Covalent chemical modifications of cellular RNAs directly impact all biological processes. However, our mechanistic understanding of the enzymes catalyzing these modifications, their substrates and biological functions, remains vague. Amongst RNA modifications N<sup>6</sup>-methyladenosine (m<sup>6</sup>A) is widespread and found in messenger (mRNA), ribosomal (rRNA), and noncoding RNAs. Here, we undertook a systematic screen to uncover new RNA methyltransferases. We demonstrate that the methyltransferase-like 5 (METTL5) protein catalyzes m<sup>6</sup>A in <i>18S</i> rRNA at position A<sub>1832</sub> We report that absence of <i>Mettl5</i> in mouse embryonic stem cells (mESCs) results in a decrease in global translation rate, spontaneous loss of pluripotency, and compromised differentiation potential. METTL5-deficient mice are born at non-Mendelian rates and develop morphological and behavioral abnormalities. Importantly, mice lacking METTL5 recapitulate symptoms of patients with DNA variants in <i>METTL5</i>, thereby providing a new mouse disease model. Overall, our biochemical, molecular, and in vivo characterization highlights the importance of m<sup>6</sup>A in rRNA in stemness, differentiation, development, and diseases.
Growth of Loblolly Pine Treated With Hexazinone, Sulfometuron Methyl, and Metsulfuron Methyl For Herbaceous Weed Control (1985)

Abstract Aerial application of 0.25 pounds active ingredient per acre of sulfometuron methyl [Oust(TM), formerly DPX-5648] or 2.0 pounds of hexazinone [Velpar L (TM)] postemergent in May 1982, resulted in good weed control. Weeds controlled on the silty clay coastal plain soil included pokeweed (Phytolacca americana L.), ragweed (Ambrosia sp.), goldenrod (Solidago sp.), and evening primrose (Oenothera sp.). Growth of 1-year-old loblolly pine (Pinus taeda L.) seedlings released with sulfometuron methyl or hexazinone was significantly improved in comparison to untreated seedlings. No significant pine mortality was associated with either treatment. On similar sites where blackberry (Rubus sp.), honeysuckle (Lonicera japonica Thunberg), and herbaceous weeds are the major problem, application of sulfometuron methyl from pre-emergence to the postemergent stage (when weeds are up to 12 to 18 inches in height) is recommended. Hexazinone is recommended as a postemergent treatment for herbaceous weed control. Treatment with metsulfuron methyl (formerly DPX-T6376-21) did not result in any growth responses significantly greater than untreated seedlings. Impacts of deer browsing on seedlings resulted in a slight height reduction the first and second growing seasons following planting but by the end of the third growing season browsed seedlings had made up the difference. No diameter differences were associated with deer browsing at any time during the study.
Effect of Swell Pressure on GCL Cover Stability (1997)

This paper describes the importance of bentonite swell pressure on the stability of cover systems that incorporate a geosynthetic clay liner (GCL). The results of a one-dimensional swell test indicate that the field swell pressure of a needle-punched GCL ranges from 35 to 40 kPa. An effective normal stress at or near this swell pressure may be required to maximize the contact area between the GCL and geomembrane and increase the static and seismic stability of a GCL cover. Since an effective normal stress of 35 to 40 kPa is probably not practical and a soil cover is usually not immediately placed, it is recommended that free swell conditions be assumed for GCL shear testing and the slope be designed using the resulting shear strength parameters. Suggestions for modifying existing products to increase GCL cover stability are also presented.
Evanescent-Coupling-Assisted Four-Wave Mixing in a Silicon Directional Coupler (2013)

Evanescent-coupling-induced group velocity dispersion (GVD) in a subwavelength silicon directional coupler is observed to significantly modify four-wave-mixing (FWM) spectra. As the separation between two silicon wires decreases, the increasing dispersion gradually suppresses the FWM gain.
Distribution and properties of water-soluble arabinogalactan proteins in vegetables. (1988)

先にキャベツ葉について著者らが開発した新しい水可溶性成分の抽出法を13種類の野菜に適応し, 得られた水可溶性成分の中に含まれるアラビノガラクタンプロテイン (AGP) の分子量分布と化学組成分析を行い, 以下のことが明らかになった。1) 試料として用いたすべての野菜には分子量の異なる2種のAGP (A-IおよびA-II) が存在する。また, これらA-IおよびA-IIの溶出パターンはタイプA [茎菜類, 淡色葉菜類, 果菜類, 豆類 (莢) および根菜類], タイプB [豆類 (種子) およびフキ (茎)] およびタイプC (緑色葉菜類) の三つに分類できる。これらのデータの比較検討から葉のA-IおよびA-IIの分布状態は緑化またはそれに伴う繊維化によって影響されていることが示唆された。2) 各野菜から分取したA-IおよびA-IIの化学的性質を分析した結果, A-Iは分子量20～60万, 中性糖含量75～85%, タンパク質含量15～25%であり, A-IIは分子量9～13万, 中性糖含量80～90%, タンパク質含量10～20%であることがわかった。A-IおよびA-IIの糖部分はいずれもアラビノースとガラクトースで構成されるアラビノガラクタンであり, A-IおよびA-IIともにそのガラクトース/アラビノースの比は野菜の種類により大きく変動した (0.5～2.0)。また, A-IおよびA-IIはいずれもAGPに特有なヒドロキシプロリンとセリンを含み, かつグリシンおよびアラニン含量が高い点で特徴的であるが, ヒドロキシプロリン含量は野菜の種類によって大きく変動した。

AMMONIUM CHLORIDE AS A NITROGEN SOURCE FOR STEERS (1972)

Two feedlot trials were conducted to measure the effects on steer performance when supplementing finishing rations with different levels of ammonium chloride (NH 4 Cl). Feedlot performance of steers supplemented with 37.4 g NH 4 Cl per head daily, which replaced equivalent amounts of cottonseed meal nitrogen in the basal ration, was equal to that of steers fed the basal ration. However, when 75.5, 113.3, and 133.5 g NH 4 Cl were fed daily, steer gains were significantly reduced. Steers receiving 75.5, 113.3, or 133.5 g NH 4 Cl consumed only 96.4, 90.3, or 85.6%, respectively, of the total ration as those receiving 37.4 g NH 4 Cl daily. Rumen pH and plasma urea levels increased slightly as the level of dietary NH 4 Cl increased. Plasma threonine and phenylalanine decreased and plasma arginine, aspartic acid, and glutamic acid increased as the level of NH 4 Cl in the diet increased. Total plasma essential and nonessential amino acid concentrations were highest when cottonseed meal was fed and lowest when the highest level of NH 4 Cl (133.5 g/head per day) was fed.
Carbon Dioxide Electroreduction using a Silver–Zinc Alloy (2017)

Abstract We report on CO 2 electroreduction activity and selectivity of a polycrystalline AgZn foil in aqueous bicarbonate electrolyte. X‐ray photoelectron spectroscopy (XPS) and X‐ray diffraction (XRD) measurements show that the alloy foil was slightly enriched in zinc both at the surface and in the bulk, with a surface alloy composition of 61.3±5.4 at % zinc and with Ag 5 Zn 8 as the most prominent bulk phase. AgZn is active for CO 2 reduction; CO is the main product, likely due to the weak CO binding energy of the surface, with methane and methanol emerging as minor products. Compared to pure silver and pure zinc foils, enhancements in activity and selectivity for methane and methanol are observed. A five‐fold increase is observed in the combined partial current densities for methane and methanol at −1.43 V vs. the reversible hydrogen electrode (RHE), representing a four‐ to six‐fold increase in faradaic efficiency. Such enhancements indicate the existence of a synergistic effect between silver and zinc at the surface of the alloy that contributes to the enhanced formation of further reduced products.
Option-Specific Program Outcomes to Meet Biological Engineering Program Criteria (2010)

Program outcomes are defined by ABET as narrow statements that describe the skills that students should possess at the time of graduation. ABET specifies a set of outcomes that should be met by all engineering programs. In order to demonstrate that the curriculum adequately meets specific program criteria, one alternative is to define additional outcomes with respect to the program criteria. Many traditional agricultural engineering programs must now meet ABET-defined program criteria for biological engineering. While these departments are offering curricula aimed at achieving an advanced knowledge of biology, chemistry, and engineering sciences, departments may also wish to continue to offer agricultural engineering subject matter to meet the needs of their constituents. Within a single degree program, this creates an interesting merge between conventional agricultural engineering and modern biological engineering curricula. The objective of this paper is to demonstrate how one department is attempting to merge these emphases and satisfy ABET accreditation. The Biosystems Engineering program at Oklahoma State University attempts to meet both needs through four degree options. To meet the biological engineering program criteria and advanced knowledge of biology and chemistry in each option, option-specific outcome statements and performance criteria were defined. Each option-specific outcome states that students should have an ability to apply the physical, chemical, biological, and engineering sciences to solve problems at the interface of biology and engineering relative to the options emphasis. The program believes that this strategy appropriately recognizes the differential definition of advanced biology and chemistry and a working knowledge of advanced biological sciences in the curriculum. A two-tiered assessment approach is then used to assess required ABET outcomes and the programs option-specific outcome. This approach appears to lessen additional work load on faculty members relative to accreditation while at the same time investigating specific details of any curriculum concerns that arise from assessment and evaluation.
Gypenosides improve diabetic cardiomyopathy by inhibiting ROS‐mediated NLRP3 inflammasome activation (2018)

NLRP3 inflammasome activation plays an important role in diabetic cardiomyopathy (DCM), which may relate to excessive production of reactive oxygen species (ROS). Gypenosides (Gps), the major ingredients of Gynostemma pentaphylla (Thunb.) Makino, have exerted the properties of anti-hyperglycaemia and anti-inflammation, but whether Gps improve myocardial damage and the mechanism remains unclear. Here, we found that high glucose (HG) induced myocardial damage by activating the NLRP3 inflammasome and then promoting IL-1β and IL-18 secretion in H9C2 cells and NRVMs. Meanwhile, HG elevated the production of ROS, which was vital to NLRP3 inflammasome activation. Moreover, the ROS activated the NLRP3 inflammasome mainly by cytochrome c influx into the cytoplasm and binding to NLRP3. Inhibition of ROS and cytochrome c dramatically down-regulated NLRP3 inflammasome activation and improved the cardiomyocyte damage induced by HG, which was also detected in cells treated by Gps. Furthermore, Gps also reduced the levels of the C-reactive proteins (CRPs), IL-1β and IL-18, inhibited NLRP3 inflammasome activation and consequently improved myocardial damage in vivo. These findings provide a mechanism that ROS induced by HG activates the NLRP3 inflammasome by cytochrome c binding to NLRP3 and that Gps may be potential and effective drugs for DCM via the inhibition of ROS-mediated NLRP3 inflammasome activation.
Limbic encephalitis and small cell lung cancer. Clinical and immunological features (1997)

Paraneoplastic limbic encephalitis (LE) is considered a particular manifestation of paraneoplastic encephalomyelitis (PEM), a remote effect of cancer almost always associated with anti-neuronal antibodies (anti-Hu; also called ANNA 1) and small cell lung carcinoma (SCLC). In order to define the frequency of anti-Hu antibodies in LE with SCLC and to analyse possible clinical differences between patients with and without anti-Hu antibodies, the charts of 16 patients with LE and SCLC were reviewed. Eight patients (50%) had anti-Hu antibodies (anti-Hu+) whereas eight patients (50%) had no detectable anti-neuronal antibodies (anti-Hu-). The clinical and laboratory features of LE and time to diagnosis of SCLC were similar in the anti-Hu+ and anti-Hu- groups. Involvement of other areas of the nervous system compatible with the diagnosis of PEM was observed in seven (87.5%) patients of the anti-Hu+ group but in only one (12.5%) of the anti-Hu- group (P = 0.012). Five patients, including four of the anti-Hu- group, had a partial improvement of the LE after treatment of the SCLC. Another anti-Hu- patient improved spontaneously. Six patients of the anti-Hu+ group died from the neurological disorder, whereas in the anti-Hu- group the cause of death was progression of the SCLC in the three patients who died. The results of this study indicate that the absence of anti-Hu antibodies does not rule out the presence of an underlying SCLC in patients with a clinical diagnosis of LE. Patients with LE and SCLC who are without anti-Hu antibodies are less likely to develop PEM and seem to improve more often after treatment of the cancer than those who present anti-Hu antibodies.
An Autonomous, Broadband, Multi-channel Neural Recording System for Freely Behaving Primates (2006)

Successful laboratory proof-of-concept experiments with neural prosthetic systems motivate continued algorithm and hardware development. For these efforts to move beyond traditional fixed laboratory setups, new tools are needed to enable broadband, multi-channel, long duration neural recording from freely behaving primates. In this paper we present a dual-channel, battery powered, neural recording system with integrated 3-axis accelerometer for use with chronically implanted electrode arrays. The recording system, called HermesB, is self-contained, autonomous, programmable and capable of recording broadband neural and head acceleration data to a removable compact flash card for up to 48 hours.
Capturing Dynamic Textured Surfaces of Moving Targets (2016)

We present an end-to-end system for reconstructing complete watertight and textured models of moving subjects such as clothed humans and animals, using only three or four handheld sensors. The heart of our framework is a new pairwise registration algorithm that minimizes, using a particle swarm strategy, an alignment error metric based on mutual visibility and occlusion. We show that this algorithm reliably registers partial scans with as little as 15% overlap without requiring any initial correspondences, and outperforms alternative global registration algorithms. This registration algorithm allows us to reconstruct moving subjects from free-viewpoint video produced by consumer-grade sensors, without extensive sensor calibration, constrained capture volume, expensive arrays of cameras, or templates of the subject geometry.
Robust health stream processing (2007)

As the cost of personal health sensors decrease along with improvements in battery life and connectivity, it becomes more feasible to allow patients to leave full-time care environments sooner. Such devices could lead to greater independence for the elderly, as well as for others who would normally require full-time care. It would also allow surgery patients to spend less time in the hospital, both pre- and post-operation, as all data could be gathered via remote sensors in the patients home. While sensor technology is rapidly approaching the point where this is a feasible option, we still lack in processing frameworks which would make such a leap not only feasible but safe. This work focuses on developing a framework which is robust to both failures of processing elements as well as interference from other computations processing health sensor data. We work with 3 disparate data streams and accompanying computations: electroencephalogram (EEG) data gathered for a brain-computer interface (BCI) application, electrocardiogram (ECG) data gathered for arrhythmia detection, and thorax data gathered from monitoring patient sleep status.
Ion-bombardment glow discharge furnaces for atomic emission spectroscopy. (1990)

Two glow discharge plasma devices for the atomic emission analysis of aqueous samples were investigated. The devices use thermal vaporization of samples from a graphite cathode coupled with glow-discharge excitation. Furnace heating of the cathode is accomplished by the positive ion bombardment of the cathode during plasma operation. One device uses a 1.6-mm diameter, 12-mm long cylindrical-post cathode, while the other uses a 3.1-mm o. d., 2.4-mm i. d., 12.7-mm deep hollow cathode. The dc plasma operates in Ar at 0.5-5.0 torr, with currents up to 250 mA. A cw, axial magnetic field of up to 1.25 kG is applied to the cylindrical-post cathode system to reduce electron losses, thereby increasing plasma excitation and ionization efficiency. The field results in a substantial reduction in plasma voltage under constant-current operation, and alters the emission radiation intensity from many plasma species. The magnetic field has much less effect on the hollow cathode furnace. At lower currents, cathode heating is insignificant. At higher currents, the cathodes heat to temperatures as high as 2500$\sp\circ$C in the case of the cylindrical-post cathode. Hollow-cathode heating temperatures are lower under comparable conditions, due to the larger cathode surface area, greater cathode mass, and lower power dissipation. The peak furnace temperature using this configuration is approximately 2100$\sp\circ$C. The role of the emission of thermionic electrons from the hot cathodes in limiting the cathode heating and in regulating the cathode temperature are considered. Sample residues of up to 50 ng of the analyte are vaporized from the cylindrical-post cathode within a few seconds of the initiation of the discharge, resulting in a transient emission intensity profile. With the hollow-cathode furnace, vaporization may take several seconds. Although a lower rate of cathode heating and a lower maximum temperature are observed for the hollow cathode, the longer sample vapor residence time results in limits of detection which are one to two orders of magnitude lower than those achieved using the cylindrical-post cathode system. For the hollow cathode, limits of detection are on the order of 10 pg to 1 ng.
