A methodology and algorithms for the design of hard real-time multitasking ASICs (1999)

Traditional high-level synthesis concentrates on the implementation of a single task (e.g. filter, linear controller, A/D converter). However, many applications—multifunctional embedded controllers intelligent wireless end-points, and DSP and multimedia servers—are defined as sets of several computational tasks. This paper describes new techniques for the synthesis of ASIC implementations that realize multiple computational processes under hard real-time constraints. Our synthesis methodology establishes connections between two important comengineering domains: operating systems and behavioral synthesis. Our hierarchical approach starts from an incompletely-specified preliminary solution and uses, interchangeably, operating system and behavioral synthesis techniques to derive increasingly more detailed and accurate design solutions. We have experimented with both optimal and heuristic algorithms to implement this methodology. The optimal algorithm uses several heuristics to speed up the average run time of an exhaustive branch-and-bound search. Force-directed optimization is the core of the heuristic synthesis method. Analysis of the proposed algorithms and the experiments shows that matching the number of bits and type of operational in taskes assigned to the same application-specific processor was the most important factor in obtaining area-efficient designs.
Phosphorylation of eIF2α triggered by mTORC1 inhibition and PP6C activation is required for autophagy and is aberrant in PP6C-mutated melanoma (2015)

Amino acid deprivation promotes the inhibition of the kinase complex mTORC1 (mammalian target of rapamycin complex 1) and activation of the kinase GCN2 (general control nonrepressed 2). Signaling pathways downstream of both kinases have been thought to independently induce autophagy. We showed that these two amino acid-sensing systems are linked. We showed that pharmacological inhibition of mTORC1 led to activation of GCN2 and phosphorylation of the eukaryotic initiation factor 2α (eIF2α) in a mechanism dependent on the catalytic subunit of protein phosphatase 6 (PP6C). Autophagy induced by pharmacological inhibition of mTORC1 required PP6C, GCN2, and eIF2α phosphorylation. Although some of the PP6C mutants found in melanoma did not form a strong complex with PP6 regulatory subunits and were rapidly degraded, these mutants paradoxically stabilized PP6C encoded by the wild-type allele and increased eIF2α phosphorylation. Furthermore, these PP6C mutations were associated with increased autophagy in vitro and in human melanoma samples. Thus, these data showed that GCN2 activation and phosphorylation of eIF2α in response to mTORC1 inhibition are necessary for autophagy. Additionally, we described a role for PP6C in this process and provided a mechanism for PP6C mutations associated with melanoma.

Experimental study and electric field simulation of a UHV saddle field gauge with a CNT field emitter (2005)

An ion-gauge was developed on the basis of electrostatic saddle field confinement which is capable of producing long electron path and consequently efficient gas phase ionization. The ion-gauge with carbon-nanotube (CNT) field emitter shows very small electrode sizes and low outgassing/sorption rates. Its performance is as follows:grounded cathode,anode potential 1750 V, grid potential 88 V and gauge sensitivity factor 1.05 Pa~(-1) in air. The power consumption for the gauge is less than 7 mW.
Azoinitiatoren, 9.Synthese und pfropfung azogruppenhaltiger polycarbonate (1979)

Abstract Polycarbonate 3 was synthesized by copolymerisation of 4‐( p ‐hydroxyphenylisopropyl)phenol with [3,5‐Bis(hydroxymethyl)phenylazo]‐methylmalonodinitrile ( 2a ). This azo groups containing polycarbonate was employed as initiator for graft copolymerisations. The content of azo functions in the resulting copolymers was determined by 1 H NMR, microanalysis, and DSC‐measurements, and M n by vapor pressure osmometry. Grafting was carried out with styrene in 1,4‐dioxane and the resulting products were characterized by IR, 1 H NMR, HPLC, and vapor pressure osmometry.
Highly‐accelerated Bloch‐Siegert mapping using joint autocalibrated parallel image reconstruction (2013)

The proposed approach allows high acceleration factors in Bloch-Siegert |B(1)(+)| mapping and can significantly reduce the scan time requirements for mapping the |B(1)(+)| fields of transmit arrays.
Collaborative information retrieval (CIR) (2000)

Most information retrieval and management tools have been developed for use by individuals. For example, Web search interfaces, and online catalogs support individual searchers working on their own. In workplace and library settings, however, teamwork is becoming more and more prevalent. We use the term Collaborative Information Retrieval (CIR) to describe any activity that collectively resolves an information problem. Information retrieval is construed in the broadest sense and includes processes such as: problem identification, analysis of information needs, query formulation, retrieval interactions, and the presentation and analysis of results. In this SIG, we will explore how to better understand and support information access in collaborative team settings. An understanding of the social and organizational contexts in which CIR occurs will lead to the design of more useful systems.Several researchers have addressed aspects of CIR. In previous CHI meetings, Kidd (CHI'94) described how different people make different sense of the same information, Maltz and Ehrlich (CHI'95) outlined the key role that information gate keepers play, and several groups studied collaborative filtering. Some products support workgroup scheduling, document workflow, etc. But, none has brought together the variety of perspectives we believe are critical in fully understanding the CIR design space.
Chronic blockade of bioelectric activity in neonatal rat cortex grown <i>in vitro</i>: Morphological effects (1991)

Culture thickness, numerical density of neurons and neuronal survival were studied in timed series of control and tetrodotoxin-silenced neocortical cultures to provide information on the role of bioelectric activity on neuronal development. In control cultures, culture thickness and number of surviving neurons decrease during the first weeks in vitro, but remain constant between 2 and 3 weeks indicating that the cultures are essentially mature. In the 4th week in vitro a further decrease in surviving neurons was observed. In tetrodotoxin-treated cultures the number of surviving neurons decreased significantly between 1 and 2 weeks in vitro, to remain constant thereafter. However, culture thickness significantly increased at 3 and 4 weeks in vitro after an initial drop between 1 and 2 weeks. Compared to age-matched controls at 2 and 3 weeks in vitro, only ca 50% of the neurons survived the loss of bioelectric activity. Similar differences were present between 1 and 2 weeks. Thus, the loss of all measurable bioelectric activity induces neuronal death in neocortical explants, but promotes neuropil formation by the surviving cells.
Organic NLO Polymers. 2. Main-Chain and Guest-Host Chi(2)NLO Polymers: NLO-phore Structure Versus Poling (1994)

Several new dipolar main-chain X (2) nonlinear optical (NLO) polymers were prepared in the study. The NLO-phores, based on alkoxy substituted alpha- cyanoacrylates, were also placed as monomeric guests within a poly(methyl methacrylate) host. Polar alignment of the NLO-phores by corona poling and their relaxation behavior was monitored by detecting the optical signal resulting from second harmonic generation. By making small variations in the structure of the NLO-phore, it was found that when hydrogen-bonding groups are rigidly coupled to the NLO-phore they are very effective for retaining polar asymmetry induced by poling and induced no deleterious effects on the alignment process. For main- chain NLOPs, it appears that for optimum alignment the bonding-axis and the polar-axis should not be parallel. NonLinear Optical, Corona Poling, Rigid-Rod Polymers

Extending Video Decoding Energy Models for 360° and HDR Video Formats in HEVC (2019)

Research has shown that decoder energy models are helpful tools for improving the energy efficiency in video playback applications. For example, an accurate feature-based bit stream model can reduce the energy consumption of the decoding process. However, until now only sequences of the SDR video format were investigated. Therefore, this paper shows that the decoding energy of HEVC-coded bit streams can be estimated precisely for different video formats and coding bit depths. Therefore, we compare a state-of-the-art model from the literature with a proposed model. We show that bit streams of the 360°, HDR, and fisheye video format can be estimated with a mean estimation error lower than 3.88% if the setups have the same coding bit depth. Furthermore, it is shown that on average, the energy demand for the decoding of bit streams with a bit depth of 10-bit is 55% higher than with 8-bit.
Cavity model analysis of differential dual‐polarised annular‐ring patch antenna (2019)

The four‐port cavity model is presented to study a differential dual‐polarised annular‐ring patch antenna operating at higher order mode TM 12 . Acceptable agreements among calculated, simulated, and measured impedances and radiation patterns are obtained. Theoretical analysis shows that the differential port‐to‐port coupling impedance is zero, and its isolation is theoretically infinite. The differential input impedance is about four times of the single‐ended input impedance at the resonant frequency of higher order mode TM 12 . The differential operation can suppress the adjacent modes TM 02 and TM 22 near the operating mode TM 12 and lead to a more symmetrical E‐plane radiation pattern and lower cross polarisation level.
Real-Time Adaptive Camera Tamper Detection for Video Surveillance (2009)

Criminals often resort to camera tampering to prevent capture of their actions. Real-time automated detection of video camera tampering cases is important for timely warning of the operators. Tampering is generally done by obstructing the camera view by a foreign object, displacing the camera and changing the focus of the camera lens. In automated camera tamper detection systems, low false alarm rates are important as reliability of these systems is compromised by unnecessary alarms and consequently the operators start ignoring the warnings. We propose adaptive algorithms to detect and identify such cases with low false alarms rates in typical surveillance scenarios where there is significant activity in the scene.
Measurement of the Intersheet Shear Along the Chain Axis in Nylon 6 (2001)

X-ray and electron diffraction studies on solution-grown crystals of high-fidelity, monodisperse nylon 6 oligoamides have provided the opportunity to measure, by experiment, the intersheet chain-axis, or c-axis shear (Δc). For almost 50 years this Δc value for the classical α-structure of nylon 6 has been taken, by analogy with nylon 6 6, to be 0.37 nm. Our evidence suggests that the Δc value is likely to be 0.14 nm and certainly lower than 0.21 nm. In addition to crystallizing the 5-amide nylon 6 oligomer in the alternating intersheet-sheared α-structure, we have crystallized this monodiperse oligomer in the progressively intersheet-sheared λ-structure. In this structure we find that Δc = 0.35 nm, a value we have also independently discovered for the λ-structure of nylon 8. Modeling the intersheet interaction energy, as a function of incrementally changing Δc, gives two Δc values: 0.14 and 0.36 nm. These values closely match our experimental results.
Dense Semantic Labeling with Atrous Spatial Pyramid Pooling and Decoder for High-Resolution Remote Sensing Imagery (2018)

Dense semantic labeling is significant in high-resolution remote sensing imagery research and it has been widely used in land-use analysis and environment protection. With the recent success of fully convolutional networks (FCN), various types of network architectures have largely improved performance. Among them, atrous spatial pyramid pooling (ASPP) and encoder-decoder are two successful ones. The former structure is able to extract multi-scale contextual information and multiple effective field-of-view, while the latter structure can recover the spatial information to obtain sharper object boundaries. In this study, we propose a more efficient fully convolutional network by combining the advantages from both structures. Our model utilizes the deep residual network (ResNet) followed by ASPP as the encoder and combines two scales of high-level features with corresponding low-level features as the decoder at the upsampling stage. We further develop a multi-scale loss function to enhance the learning procedure. In the postprocessing, a novel superpixel-based dense conditional random field is employed to refine the predictions. We evaluate the proposed method on the Potsdam and Vaihingen datasets and the experimental results demonstrate that our method performs better than other machine learning or deep learning methods. Compared with the state-of-the-art DeepLab_v3+ our model gains 0.4% and 0.6% improvements in overall accuracy on these two datasets respectively.
CASTING OUT DEMONS: HOMAGE TO SHIRLEY JACKSON (2012)

Atividade intensa e efusiva concernente à escritora norte-americana Shirley Jackson tem sido percebida desde as últimas décadas do século XX até o início do XXI. O período que imediatamente sucedeu sua morte em 1965 prenunciava uma resposta que levou uma série de críticos a postularem Jackson como uma escritora esquecida. Frequentemente referindo-se a ela como uma autora de ficção bizarra e de terror. Jackson, por razões estranhas, aceitou o rótulo, embora uma minoria de sua produção literária de fato traga elementos sobrenaturais ou temas góticos. O presente texto deseja prestar uma homenagem a esta escritora supostamente pouco apreciada e relegada ao esquecimento que, no entanto, influencia muitos escritores célebres e obras canônicas até os dias de hoje, e que mudou e continua a mudar a história da literatura americana e mundial de maneira indelével.
Crystal size distribution dynamics in a classified crystallizer: Part I. Experimental and theoretical study of cycling in a potassium chloride crystallizer (1977)

Abstract Cycles in particle size and slurry density were experimentally observed in a mixed suspension, potassium chloride crystallizer equipped with a fines dissolver and having nonrepresentative product withdrawal. Cycling behavior was achieved with a product crystal elutriator but was also observed with changes in the orientation of the product removal tube, indicating that instability was induced by product classification. Simulation of the unstable runs with a dynamic model showed crystal size distribution (CSD) limit cycles of similar period using nucleation kinetics and process conditions measured experimentally. The computer simulation showed no tendency towards cycling for the stable runs.
Molecular weight controlled poly(amic acid) resins end‐capped with phenylethynyl groups for manufacturing advanced polyimide films (2017)

ABSTRACT To investigate the effect of reactive end‐capping groups on film‐forming quality and processability, a series of molecular weight‐controlled aromatic poly(amic acid) (PAA) resins functionalized with phenylethynyl end groups were prepared via the polycondensation of 3,3′,4,4′‐biphenyltetracarboxylic dianhydride (BPDA), para ‐phenylenediamine (PDA), and 4‐phenylethynyl phthalic anhydride (PEPA) served as molecular‐weight‐controlling and reactive end capping agent. The PAA resins with relatively high concentrations endow enhanced wetting/spreading ability to form PAA gel films by solution‐cast method which were thermally converted to the fully‐cured polyimide (PI) films. The mechanical and thermal properties of PI films were investigated as a function of PAA molecular weights ( M n ) and thermal‐curing parameters. Mechanical property, dimensional stability and heat resistance of the fully‐cured PI films with PAA M n > 20 ×10 3 g mol −1 are found to be better than that of their unreactive phthalic end‐capped counterparts. The covalent incorporation of chain‐extension structures in the backbones, induced by thermal curing of phenylethynyl groups, might facilitate yielding a higher degree of polymer chain order and consequently improved resistance strength and elongation at break to tensile plastic deformation. © 2017 Wiley Periodicals, Inc.

Diet-dependent carcinogenesis of pancreatic islets and liver in transgenic mice expressing oncogenes under the control of the L-type pyruvate kinase gene promoter. (1992)

The liver-type pyruvate kinase (L-PK) gene is controlled positively by insulin and carbohydrates, negatively by glucagon and fasting. Diet-inducible models of carcinogenesis were obtained using the L-PK gene promoter and regulatory sequences to control the expression of c-myc and SV40 T oncogenes in transgenic mice. L-PK/c-myc and L-PK/Tag animals fed a carbohydrate-rich diet developed hepatocarcinomas. In addition, L-PK/Tag animals developed diet-dependent, aggressive endocrine pancreatic tumors, preceded by islet hyperplasia involving the different analysed cell populations (alpha, beta and delta). Expression of the L-PK gene was demonstrated in pancreatic tumors, in rat isolated islets and in rat insulinoma-derived cells (RIN line), revealing a new tissue specificity of the L-PK gene. Our results suggest that this gene may be expressed in islet progenitor cells from which the different mature endocrine cells derive.
Designing a magnetodynamic stable suspension system (1999)

This paper presents a method for designing a magnetodynamic suspension system that ensures a strict local minimum of system potential energy along the assigned trajectory of its levitator flight. The magnetic field and forces of the system are calculated in the domain of its variable parameters restricted by the conditions of stable equilibrium. The algorithm of the solution, a sample evaluation of the system, and the calculation of the vehicle natural oscillations under transient external effects are presented.
New Forms of Deep Learning on the Web (2009)

We claim that the Web has the potential to be a quintessential multimedia environment for complex learning, particularly in ill-structured domains. This chapter explores the cognitive load considerations associated with several aspects of deep and extended learning on the Web. We also propose the need for a reconceptualization of Cognitive Load Theory for comprehension and learning in more ill-structured conceptual arenas. This reconceptualization emphasizes the need for learning approaches that promote flexible knowledge assembly through processes of organic, reciprocal, and deep Web learning.
Method and circuit for finding the coordinate of the center of a particle track on a scanning automaton (1975)

Hypernatremia in Hospitalized Patients (1996)

Although the development of hypernatremia before hospital admission occurs primarily in geriatric patients, hospital-acquired hypernatremia was more common in our cohort and had an age distribution similar to that of the general hospitalized population. Hospital-acquired hypernatremia was primarily iatrogenic, resulting from inadequate and inappropriate prescription of fluids to patients with predictably increased water losses and impaired thirst or restricted free water intake or both. Treatment of hypernatremia is often inadequate or delayed. Efforts to manage hypernatremia better and altogether avoid hospital-acquired hypernatremia should focus on both physician education and the development of hospital systems to prevent errors in fluid prescription.
