A Cyclic Simple Shear Apparatus for Dry Granular Materials (1978)

Abstract The development of a simple shear apparatus for cyclic loading of dry granular material is described. Full details of the equipment are given together with information on its performance. The motivation for this work was provided by the need to determine the response of granular material in roads and railroads to the modes of cyclic loading imposed by moving traffic. The equipment is relatively simple and is operated by pneumatic rams. Stress conditions on the central third of a rectangular specimen are measured by load cells attached to the loading platens. The top platen is split into three parts to allow differential dilation of the specimen to occur when failure conditions are approached near the ends. Thus, uniform stress conditions are maintained over the central third. Both one directional and reversed shear tests can be performed at frequencies up to about 0.5 Hz on specimens 210 by 140 by 30 mm.
Transatlantic Earth Potential Variations During the March 1989 Magnetic Storms (1989)

Measurements of the cable power supply voltage at the North American end of the fiber optic transatlantic telecommunications cable TAT‐8 during the March 1989 magnetic storm has provided a measure of the large scale changes in the total Earth potential across the Atlantic during the storm interval. East‐west potential changes as large as 700 volts (∼0.12 volts/km) peak‐to‐peak were observed, with many smaller amplitude variations also seen. The largest variations in Earth potential occurred during an extended interval of a very intense eastward electrojet as measured by a magnetometer at the North American terminus of the cable. The eastward electrojet current probably exceeded 10 6 amps. The design of the TAT‐8 cable power feed equipment is sufficiently conservative that even such unusually large Earth potentials as those measured during this storm were not a threat to the integrity of the communications system.
In Search of the Emotional Self: An fMRI Study Using Positive and Negative Emotional Words (2003)

A widely distributed network of brain areas contributes to emotional processing. Among these regions, the right dorsomedial prefrontal cortex is one main area mediating self-reference. By providing a personal perspective in the evaluation of emotional stimuli, the right dorsomedial prefrontal cortex may mediate cognitive processes, such as those involved in psychotherapy, that guide self-regulation of emotional experience.
Process modeling of hydrothermal treatment of municipal solid waste to form high solids slurries in a pilot scale system (1995)

Two models are developed for characterizing the hydrothermal decomposition of municipal solid waste (MSW) in a pilot scale facility. The process modeled involves the use of high pressure steam to directly heat surrogate MSW, newspaper, to temperatures and pressures where decomposition reactions breakdown the organic matter to form a coal like solid having properties which make it suitable as a feedstock for a commercial gasifier. One model uses the ASPEN steady-state simulator. This model is only capable of computing a limited number of process variables. To more adequately deal with the transient behavior of the inherently batch process a second transient model is formulated. The model allows important process temperatures, pressures, gas flows and compositions to be calculated as a function of time. The model has been used to scope possible operating scenarios for proposed pilot scale experiments and these results are presented. Based on computed results a recommendation is made that the first pilot experiment use a dampened feed material containing a water-to-dry newspaper ratio of 0.5 to 1. The transient model predicts that this will result in a slurry product in the reactor vessel after cooldown containing 57 wt.% water.

Screen Printed Flexible Radiofrequency Identification Tag for Oxygen Monitoring (2013)

In this work, a radiofrequency identification (RFID) tag with an optical indicator for the measurement of gaseous oxygen is described. It consists of an O2 sensing membrane of PtOEP together with a full electronic system for RFID communication, all printed on a flexible substrate. The membrane is excited by an LED at 385 nm wavelength and the intensity of the luminescence generated is registered by means of a digital color detector. The output data corresponding to the red coordinate of the RGB color space is directly related to the concentration of O2, and it is sent to a microcontroller. The RFID tag is designed and implemented by screen printing on a flexible substrate for the wireless transmission of the measurement to a remote reader. It can operate in both active and passive mode, obtaining the power supply from the electromagnetic waves of the RFID reader or from a small battery, respectively. This system has been fully characterized and calibrated including temperature drifts, showing a high-resolution performance that allows measurement of very low values of oxygen content. Therefore this system is perfectly suitable for its use in modified atmosphere packaging where the oxygen concentration is reduced below 2%. As the reading of the O2 concentration inside the envelope is carried out with an external RFID reader using wireless communication, there is no need for perforations for probes or wires, so the packaging remains completely closed. With the presented device, a limit of detection of 40 ppm and a resolution as low as 0.1 ppm of O2 can be reached with a low power consumption of 3.55 mA.
Token tenure: PATCHing token counting using directory-based cache coherence (2008)

Traditional coherence protocols present a set of difficult tradeoffs: the reliance of snoopy protocols on broadcast and ordered interconnects limits their scalability, while directory protocols incur a performance penalty on sharing misses due to indirection. This work introduces PATCH (Predictive/Adaptive Token Counting Hybrid), a coherence protocol that provides the scalability of directory protocols while opportunistically sending direct requests to reduce sharing latency. PATCH extends a standard directory protocol to track tokens and use token counting rules for enforcing coherence permissions. Token counting allows PATCH to support direct requests on an unordered interconnect, while a mechanism called token tenure uses local processor timeouts and the directorypsilas per-block point of ordering at the home node to guarantee forward progress without relying on broadcast. PATCH makes three main contributions. First, PATCH introduces token tenure, which provides broadcast-free forward progress for token counting protocols. Second, PATCH deprioritizes best-effort direct requests to match or exceed the performance of directory protocols without restricting scalability. Finally, PATCH provides greater scalability than directory protocols when using inexact encodings of sharers because only processors holding tokens need to acknowledge requests. Overall, PATCH is a ldquoone-size-fits-allrdquo coherence protocol that dynamically adapts to work well for small systems, large systems, and anywhere in between.

Cross-Lingual Genre Classification (2012)

Automated classification of texts into genres can benefit NLP applications, in that the structure, location and even interpretation of information within a text are dictated by its genre. Cross-lingual methods promise such benefits to languages which lack genre-annotated training data. While there has been work on genre classification for over two decades, none has considered cross-lingual methods before the start of this project. My research aims to fill this gap. It follows previous approaches to monolingual genre classification that exploit simple, low-level text features, many of which can be extracted in different languages and have similar functions. This contrasts with work on cross-lingual topic or sentiment classification of texts that typically use word frequencies as features. These have been shown to have limited use when it comes to genres. Many such methods also assume cross-lingual resources, such as machine translation, which limits the range of their application. A selection of these approaches are used as baselines in my experiments. I report the results of two semi-supervised methods for exploiting genre-labelled source language texts and unlabelled target language texts. The first is a relatively simple algorithm that bridges the language gap by exploiting cross-lingual features and then iteratively re-trains a classification model on previously predicted target texts. My results show that this approach works well where only few cross-lingual resources are available and texts are to be classified into broad genre categories. It is also shown that further improvements can be achieved through multi-lingual training or cross-lingual feature selection if genre-annotated texts are available in several source languages. The second is a variant of the label propagation algorithm. This graph-based classifier learns genre-specific feature set weights from both source and target language texts and uses them to adjust the propagation channels for each text. This allows further feature sets to be added as additional resources, such as Part of Speech taggers, become available. While the method performs well even with basic text features, it is shown to benefit from additional feature sets. Results also indicate that it handles fine-grained genre classes better than the iterative re-labelling method.
Transistor off-state leakage current induced by TiSi<sub>2</sub> pre-amorphizing implant in a 0.20 μm CMOS process (2000)

We report on an anomalous off-state leakage current found in NMOS devices fabricated with a pre-amorphizing (PA) implant before titanium silicide formation. We present data which indicates that the leakage current is caused by channeling of the arsenic PA implant through the polysilicon gate. An angled PA implant is shown to prevent the channeling and allow the fabrication of well-behaved devices with low resistance titanium silicide.
A Novel Hardware Architecture for Low Power and Rapid Testing of VLSI Circuits (2006)

During built-in self-test (BIST), the set of patterns generated by a pseudo-random pattern generator may use longer time and more power consumption in testing. In this paper, we propose a novel hardware architecture base on "LBIST Controller" to reduce test application time and test power consumption. Give a test cubes for stuck-at faults contain unspecified bit generated by a sequential automatic test pattern generator (ATPG). Use our propose algorithm in section III can group test cubes to several section schemes. Then mapping to our propose hardware architecture in section II. While "Section Counter" is more then zero, scan in could through MUX and bypass the flip-flops in "Fixed Group". And we can save power consumption and test application time in this time. According to our simulation result, we reduce about 20% ~ 60% power consumption and 50% ~ 80% test application time in some ISCAS'89 benchmarks
Plasma Thymidine Kinase Activity in Dogs with Lymphoma and Leukemia. (1997)

Plasma thymidine kinase (TK) activity was evaluated as a plasma marker for canine lymphoma and leukemia. A tentative "cut-off" value was set at 6.0 U/l as the upper level of plasma TK based on the mean + 2SD of plasma TK activity in 13 clinically healthy dogs. The levels of plasma TK activity in all of the 20 dogs with lymphoma and leukemia were higher than the cut-off value, whereas those in dogs with lymphoma decreased in parallel with the reduction of the tumor mass after chemotherapy. These findings suggested that estimation of plasma TK activity can be used as a plasma marker for lymphoma and leukemia in the dog.
Alterations in levels of iron, ferritin, and other trace metals in neurodegenerative diseases affecting the basal ganglia (1992)

Previously we have shown that cell death in the substantia nigra (SN) in Parkinson's disease (PD) is associated with an increase in iron content but a decrease in the level of the iron-binding protein ferritin. Alterations in other metal ion levels were also observed; copper levels were reduced, whereas zinc levels were increased. The importance of these changes in iron, ferritin, and other metal ions in the pathophysiology of PD depends on whether they are specific to the illness. We measured levels of iron, copper, zinc, manganese, and ferritin in postmortem tissue from patients with progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) (which shows pathology in the SN and striatum) and Huntington's disease (HD) (which shows pathological changes in the striatum, compared with control subjects). Total iron levels were elevated in areas of the basal ganglia showing pathological changes in these disorders. In particular, total iron content was increased in SN in PD, PSP, and MSA, but not in HD. Total iron levels in the striatum (caudate nucleus and/or putamen) were increased in PSP, MSA, and HD, but not in PD. There were no consistent alterations in manganese levels in the basal ganglia in any of the diseases studied. Copper levels were decreased in the SN in PD and in the cerebellum in PSP, and were elevated in the putamen and possibly the SN in HD. Zinc levels were only increased in PD in the SN, the caudate nucleus, and the putamen.(ABSTRACT TRUNCATED AT 250 WORDS)
Tensile and bend relationships of several surgical needle materials (1993)

Abstract Four stainless steel alloys, commonly used for surgical needles were tensile and bend tested. The materials included: ASTM 42000, ASTM 45500, ASTM 30200, and a Fe–12Cr–8.5Ni–3.2Mo–1.9Ti alloy. Small diameter wires in a wide range of strength levels were produced using various heat treatments and/or cold drawing. Samples from each processing condition were tensile and bend tested. Calculated yield moment and ultimate moment were determined using tensile yield strength, the flexural formula ( M (y) = σ (y) I / C ), and the shape factor for circular cross sections ( M (u) / M (y) = 1.7). A deviation was observed between the theoretically calculated yield moment and a 2° offset measured yield moment. This was expected because moment‐strain diagrams provide only an approximation of yield moment due to the gradual departure from linearity. The 2° offset yield was termed the surgical yield because it represents the strain at which a surgical needle would start to lose functionality. A nonlinear relationship ( R ) was observed between measured and calculated values. The relationship ( R ) proved to be a function of cold work by wire drawing as measured by the change in wire length (Δ L ), R = a − b * In(Δ L ). This suggests that engineers selecting materials for bending applications such as surgical needles cannot use tensile data alone to predict bend strength. Processing history must also be known. © 1993 John Wiley & Sons, Inc.
A novel in-service surveillance scheme for optically amplified transmission systems (1997)

We propose here a novel surveillance scheme for an optically amplified transmission system which allows simultaneous in-service fault identification for fiber and optical amplifiers. While requiring additional fiber Bragg gratings of designated wavelengths to be integrated with optical amplifiers, the monitoring light source is derived from the unused spectra of ASE and no dedicated light source is needed as in conventional OTDR technique. We have further demonstrated the scheme's feasibility with a 100-km, three-EDFA optical transmission system.
Hydrothermal Synthesis, Structure Investigation, and Oxide Ion Conductivity of Mixed Si/Ge-Based Apatite-Type Phases (2014)

Apatite-type oxides ([A(I)4][A(II)6][(BO4)6]O2), particularly those of the rare-earth silicate and germanate systems, are among the more promising materials being considered as alternative solid oxide fuel cell electrolytes. Nonstoichiometric lanthanum silicate and germanate apatites display pure ionic conductivities exceeding those of yttria-stabilized zirconia at moderate temperatures (500-700 °C). In this study, mixed Si/Ge-based apatites were prepared by hydrothermal synthesis under mild conditions rather than the conventional solid-state method at high temperatures. Single-phase and highly crystalline nanosized apatite powders were obtained with the morphology changing across the series from spheres for the Si-based end member to hexagonal rods for the Ge-based end member. Powder X-ray and neutron analysis found all of these apatites to be hexagonal (P63/m). Quantitative X-ray microanalysis established the partial (<15 at%) substitution of La(3+) by Na(+) (introduced from the NaOH hydrothermal reagent), which showed a slight preference to enter the A(I) 4f framework position over the A(II) 6h tunnel site. Moreover, retention of hydroxide (OH(-)) was confirmed by IR spectroscopy and thermogravimetric analysis, and these apatites are best described as oxyhydroxyapatites. To prepare dense pellets for conductivity measurements, both conventional heat treatment and spark plasma sintering methods were compared, with the peculiar features of hydrothermally synthesized apatites and the influence of sodium on the ionic conductivity considered.
TransformGen: automating the maintenance of structure-oriented environments (1994)

A serious problem for programs that use persistent data is that information created and maintained by the program becomes invalid if the persistent types used in the program are modified in a new release. Unfortunately, there has been little systematic treatment of the problem; current approaches are manual, ad hoc, and time consuming both for programmers and users. In this article we present a new approach. Focusing on the special case of managing abstract syntax trees in structure-oriented environments, we show how automatic transformers can be generated in terms of an implementor's changes to the grammar of these environments.
Synthesis and Characterization of Amorphous Phosphorus Nitride (2000)

Abstract Amorphous phosphorus nitride (P3N5) has been synthesized from the reaction of PCl5 and NaN3 in an autoclave at 190–300 °C. XPS, IR and TEM revealed that the product was amorphous P3N5 with flake-like morphology. The influences of experimental conditions were discussed.
T regulatory cells in cancer: recent advances and therapeutic potential (2010)

Mechanisms by which Treg functions modulate the immune response to tumors are becoming further understood. However, specific markers to tumor-specific/induced Tregs are yet to be clearly identified, which is a major limitation in optimizing strategies to specifically target Tregs in cancer. Despite this, strategies aimed at modulating Tregs in patients are providing some early encouraging results supporting the overall concept and indicating that further studies are clearly warranted.

Fas-induced proteolytic activation and intracellular redistribution of the stress-signaling kinase MEKK1 (1998)

The stress-activated protein kinase (SAPK, alternatively JNK) is activated rapidly by cell stress stimuli such as inflammatory cytokines and oxidative stress, and more slowly by the initiation of the apoptotic cell death response by events such as ligation of the Fas protein. Mitogen-activated protein kinase/Erk kinase kinase-1 (MEKK1) is an activator of SAPK, serving as a SAPK-kinase-kinase through intermediate phosphorylation of the SAPK kinase SEK1. By sequencing proteolytic cleavage products of MEKK1, we found that the proapoptotic protease caspase 3 (CPP32) cleaves MEKK1 after residue D68 both in vivo and in vitro. Cleavage of MEKK1 after D68 is blocked by viral and chemical protease inhibitors. Cleavage of MEKK1 at D68 changes the intracellular distribution of the protein from a Triton-insoluble compartment to a Triton-soluble compartment, reflected in a redistribution from a particulate to a diffuse cytoplasmic staining seen by immunofluorescence. Activation of both SAPK and MEKK1 after Fas ligation is prevented by both viral and chemical caspase 3 inhibitors, which in contrast fail to block activation of SAPK by rapidly acting cell stresses. Stress factor-induced SAPK signaling is not dependent on caspase 3 function. We propose that two mechanisms of stress signaling through MEKK1 exist. One is rapid, independent of proteases, and occurs in the particulate Triton-insoluble compartment. The other is more slowly activated and involves liberation of particulate MEKK1 by proteolytic cleavage and activation by caspase 3.
