A Stochastic Model for a Compressor Stability Measure (2006)

A stability measure rooted in the unsteady characteristics of the flow field over the compressor rotor has been previously developed. The present work explores the relationship between the stochastic properties of this measure, called the correlation measure, and the compressor stability boundary. A stochastic model has been developed to gauge the impact of the correlation measure’s stochastic nature on its applicability to compressor stability management. The genesis of this model is in the fundamental properties of a specific stochastic process, one that is created by the threshold-crossings of a random process. The model validation utilizes data obtained on three different axial compressor facilities. These include a single stage low speed axial compressor, a four stage low speed research compressor and an advanced technology demonstrator high speed compressor. This paper presents details of the model development and validation, as well as, closed loop experimental results to demonstrate correlation measure’s usefulness in compressor stability management.
Carbohydrate Metabolism in the Developing Endosperm of Rice Grains (1989)

The metabolism of carbohydrates in developing rice endosperm was characterized by a comparison of levels of activities of 33 major enzymes between the endosperm and green leaves of rice. Activities of ADPglucose pyrophosphorylase, starch synthase and branching enzyme (Q-en-zyme), compared on the basis of soluble protein content, were markedly higher in endosperm than in green leaves. The high levels of Q-enzyme may be responsible for the efficient production of starch in the rice endosperm. The measurement of levels of metabolic intermediates and the localization of key enzymes in isolated amyloplasts from rice endosperm support the view that sucrose is metabolized in the cytoplasm via the pathway: sucrose→UDPglucose→hexose-P→FBP→triose-P. Triose-P then enters the amyloplast, where it is converted to G1P via FBP and, finally, G1P is converted to starch by the concerted reactions of ADPglucose pyrophosphorylase, starch synthase and Q-enzyme.
Schizophrenia susceptibility associated with interstitial deletions of chromosome 22q11. (1995)

We report the results of two studies examining the genetic overlap between schizophrenia and velocardiofacial syndrome. In study A, we characterize two interstitial deletions identified on chromosome 22q11 in a sample of schizophrenic patients. The size of the deletions was estimated to be between 1.5 and 2 megabases. In study B, we examine whether variations in deletion size are associated with the schizophrenic phenotype in velocardiofacial syndrome patients. Our results show that a region of the genome that has been previously implicated by genetic linkage analysis can harbor genetic lesions that increase the susceptibility to schizophrenia. Our findings should facilitate identification and cloning of the schizophrenia susceptibility gene(s) in this region and identification of more homogeneous subgroups of patients.
Beyond terminology, or, the limits of 'decorative arts' (2014)

Determining the meaning, status, and future of the term ‘decorative arts’ is not merely a question of disciplinary boundaries or institutional practice, idealism or ‘success’, or a pass at the methodological smorgåsbord. This paper argues that the term ‘decorative arts’ has both a specific historical meaning and continuing relevance to other terms such as material culture and design history. This essay discusses the term and its relationship to disciplinary shifts that affected art history, design history in the UK, and material culture in the US. Furthermore, it offers a case study for current scholarship, teaching, and exhibition practice.
High-performance and energy-efficient mobile web browsing on big/little systems (2013)

Internet web browsing has reached a critical tipping point. Increasingly, users rely more on mobile web browsers to access the Internet than desktop browsers. Meanwhile, webpages over the past decade have grown in complexity by more than tenfold. The fast penetration of mobile browsing and everricher webpages implies a growing need for high-performance mobile devices in the future to ensure continued end-user browsing experience. Failing to deliver webpages meeting hard cut-off constraints could directly translate to webpage abandonment or, for e-commerce websites, great revenue loss. However, mobile devices' limited battery capacity limits the degree of performance that mobile web browsing can achieve. In this paper, we demonstrate the benefits of heterogeneous systems with big/little cores each with different frequencies to achieve the ideal trade-off between high performance and energy efficiency. Through detailed characterizations of different webpage primitives based on the hottest 5,000 webpages, we build statistical inference models that estimate webpage load time and energy consumption. We show that leveraging such predictive models lets us identify and schedule webpages using the ideal core and frequency configuration that minimizes energy consumption while still meeting stringent cut-off constraints. Real hardware and software evaluations show that our scheduling scheme achieves 83.0% energy savings, while only violating the cut-off latency for 4.1% more webpages as compared with a performance-oriented hardware strategy. Against a more intelligent, OS-driven, dynamic voltage and frequency scaling scheme, it achieves 8.6% energy savings and 4.0% performance improvement simultaneously.
Microservices-based IoT Application Placement within Heterogeneous and Resource Constrained Fog Computing Environments (2019)

Fog computing paradigm has created innovation opportunities within Internet of Things (IoT) domain by extending cloud services to the edge of the network. Due to the distributed, heterogeneous and resource constrained nature of the Fog computing nodes, Fog applications need to be developed as a collection of interdependent, lightweight modules. Since this concept aligns with the goals of microservices architecture, efficient placement of microservices-based IoT applications within Fog environments has the potential to fully leverage capabilities of Fog devices. In this paper, we propose a decentralized microservices-based IoT application placement policy for heterogeneous and resource constrained Fog environments. The proposed policy utilizes the independently deployable and scalable nature of microservices to place them as close as possible to the data source to minimize latency and network usage. Moreover, it aims to handle service discovery and load balancing related challenges of the microservices architecture. We implement and evaluate our policy using iFogSim simulated Fog environment. Results of the simulations show around 85% improvement in latency and network usage for the proposed microservice placement policy when compared with Cloud-only placement approach and around 40% improvement over an alternative Fog application placement method known as Edge-ward placement policy. Moreover, the decentralized placement approach proposed in this paper demonstrates significant reduction in microservice placement delay over centralized placement.
Use of the Rotex needle in percutaneous biopsy of pulmonary malignancy (1985)

When the characteristics of 30 biopsy needles were reviewed in a recent study using cadaveric liver tissue, the Rotex needle was judged to yield notable crush artifact, poor histologic preservation, and small sample specimens. In the current review of the Rotex needle in percutaneous lung biopsy in 121 patients, the authors report 98% sensitivity for the presence of malignancy and 94% specificity for the absence of malignancy. Although the Rotex needle has shown poor results in liver substrate studies, it proved more than adequate for obtaining lung tissue and a subsequent diagnosis of pulmonary malignancy. This apparent contradiction is explained by the fact that the diagnosis of lung malignancy can be made from cytopathologic material and does not require histologic specimens in most cases.
Non-isothermal extrudate swell (2016)

The non-isothermal extrudate swell of a high molecular weight high-density polyethylene (HDPE) in long capillary and slit dies is studied numerically (ANSYS POLYFLOW®) using an integral K-BKZ constitutive model including crystallization kinetics, determined experimentally. The Nakamura model is used for crystallization of the HDPE, where the crystallization rate parameter is evaluated by using the well-known Ziabicki equation. This non-isothermal extrudate swell phenomenon is simulated using the pseudo-time integral K-BKZ model with the Wagner damping function along with the differential form of the Nakamura model to account for the crystallization of the extrudate. The swell measurements were carried out under non-isothermal conditions by extruding the polymer melt at 200 °C through long capillary and slit dies to ambient air at 25 °C, 110 °C, and 200 °C. The numerical results are found to be in excellent agreement with experimental observations.
Refractive shape from light field distortion (2011)

Acquiring transparent, refractive objects is challenging as these kinds of objects can only be observed by analyzing the distortion of reference background patterns. We present a new, single image approach to reconstructing thin transparent surfaces, such as thin solids or surfaces of fluids. Our method is based on observing the distortion of light field background illumination. Light field probes have the potential to encode up to four dimensions in varying colors and intensities: spatial and angular variation on the probe surface; commonly employed reference patterns are only two-dimensional by coding either position or angle on the probe. We show that the additional information can be used to reconstruct refractive surface normals and a sparse set of control points from a single photograph.
New bounds on the (n, k, d) storage systems with exact repair (2015)

The exact-repair problem for distributed storage systems is considered. Characterizing the optimal storage-vs-repair bandwidth tradeoff for such systems remains an open problem for more than four storage nodes. A new family of information theoretic bounds is provided for the storage-vs-repair bandwidth tradeoff for all (n, k, d) systems. The proposed bound readily recovers Tian's result for the (4, 3, 3) system, and hence suffices for exact characterization for this system. In addition, the bound improves upon the existing bounds for the (5, 4, 4) system. More generally, it is shown that this bound characterizes the optimal boundary of the exact repair tradeoff for all distributed storage systems, with (n, k, d) = (n, n-1; n-1) when β ≤ 2α/k.
<b>An oligopeptide permease responsible for the import of an extracellular signal governing aerial mycelium formation in <i>Streptomyces coelicolor</i></b> (1996)

Morphological differentiation in the filamentous bacterium Streptomyces coelicolor is believed to involve a mechanism of extracellular signalling that culminates with the formation of an aerial mycelium. We have identified a gene cluster designated bldK in which insertional and deletion mutations cause a block in aerial mycelium formation. Extracellular complementation experiments indicate that bldK defines a step in a cascade of extracellular signals; colonies of a bldK-mutant strain extracellularly complement bld261-mutant colonies, and are themselves extracellularly complemented by bldA- and bldH-mutant colonies. The bldK locus, which is located at 5 o'clock on the genetic map and within Asel fragment "N' on the physical map, consists of five adjacent open reading frames. These genes specify homologues of the subunits of the oligopeptide-permease family of ATP-binding cassette (ABC) membrane-spanning transporters. Because bldK mutations confer resistance to the toxic tripeptide bialaphos, it is inferred that BldK is an oligopeptide importer. We propose that the BldK transporter is responsible for the import of an extracellular signalling molecule produced under the control of the wild-type product of the bld261 gene. The BldK-imported signal, in turn, causes the production of a second extracellular signal molecule that depends on the products of bldA and bldH for its action.
Benzyl Alcohol Allergy: Importance of Patch Testing with Personal Products (2005)

Benzyl alcohol is a weak sensitizer found in a wide array of plants and plant products, foods, cosmetics, and medications. Delayed contact dermatitis reactions as well as immediate, urticarial, and systemic reactions have been reported to occur with its use in these various formulations. We present the case of a woman with allergic contact dermatitis from benzyl alcohol and provide a brief review of allergy to this chemical.
A 2&#x00D7;2 W-band reference time-shifted phase-locked transmitter array in 65nm CMOS technology (2013)

This paper presents a complete 2×2 phased array transmitter system operating at W-band (90-95 GHz) which employs a PLL reference time-shifting approach instead of using traditional mm-wave phase shifters. PLL reference shifting enables a phased array to be distributed over multiple chips without the need for coherent mm-wave signal distribution between chips. The proposed phased array transmitter system consumes 248 mW per array element when implemented in a 65 nm CMOS technology.
Enhanced ECMP and Large Flow Aware Transport (2010)

Internet Traffic has constantly shown the pattern that a very small
amount of the traffic flows generate a high traffic volume while a
significant amount of small flows contribute a small amount of traffic
volume. Differentiating such large flow and small flow in the packet
switched network enables an enhanced transport method over Equal Cost
Multi Paths (ECMP). This draft describes the enhanced ECMP transport
with the large flow awareness.
High-Performance Hydrophobic Interaction Chromatography of Proteins (2021)

Hydrophobic interaction chromatography was introduced in 1957 under the name salting-out chromatography as a technique for separating substances, according to their hydrophobicities, by gradient elution with a decreasing salt concentration, which reduces the solubility of substances such as ammonium and sodium sulfates. The effects of the type of ligand of support have been studied by many workers and it has been found that retention and selectivity depend substantially on the type of ligand. Proteins are generally more retained on the supports with more hydrophobic ligands. If the ligand is too hydrophobic, it is difficult to elute proteins in native states from the column. In contrast, if the ligand is very hydrophilic, very high concentrations of salt are required to retain proteins. Supports with hydrophilic ligands can provide satisfactory results even for unstable and rather hydrophobic proteins. The usefulness of high-performance hydrophobic interaction chromatography has been demonstrated for purifications and analyses of various proteins.
ALL METAL SEALED GAS INFRARED CELL. (1964)

The controlled creation of defects in silicon carbide represents a major challenge. A well-known and efficient tool for defect creation in dielectric materials is the irradiation with swift (E(kin) ≥ 500 keV/amu) heavy ions, which deposit a significant amount of their kinetic energy into the electronic system. However, in the case of silicon carbide, a significant defect creation by individual ions could hitherto not be achieved. Here we present experimental evidence that silicon carbide surfaces can be modified by individual swift heavy ions with an energy well below the proposed threshold if the irradiation takes place under oblique angles. Depending on the angle of incidence, these grooves can span several hundreds of nanometres. We show that our experimental data are fully compatible with the assumption that each ion induces the sublimation of silicon atoms along its trajectory, resulting in narrow graphitic grooves in the silicon carbide matrix.
Morphological Control of Hydrothermal Ni(OH)<sub>2</sub> in the Presence of Polymers and Surfactants: Nanocrystals, Mesocrystals, and Superstructures (2008)

Polymers with different hydrophilic groups [polyvinylpyrrolidone (PVP), ammonium polyacrylate (APA), and hydroxypropylmethyl cellulose (HPMC)] and surfactants [cetyltrimethylammonium bromide (CTAB) and sodium dodecylbenzensulfonate (SDBS)] were used as additives to modify the crystallization of β-Ni(OH)2 in hydrothermal conditions. Marked morphological changes in the β-Ni(OH)2 particles were observed depending on the additive concentration and on the duration of the hydrothermal treatment. The final morphology is the result of a complex, time-dependent self-assembly and growth process. Well-defined particles with sizes from submicrometer range to a few micrometers corresponding to hexagonal lamellae, hexagonal tabular mesocrystals, rosette- and flowerlike aggregates of lamellae, hexagonal prismatic mesocrystals, and acicular nanocrystals were easily obtained after a short time (2−24 h) aging at 150−200 °C. With PVP and CTAB, there is evidence of a growth process dominated by self-assembly of nanocrystals to produce mesocrystals. The formation of spherical superstructures (with SDBS, up to 70 μm in diameter) and hollow spheres (with PVP) is observed at long times (>24 h) as a result of solvent-mediated recrystallization processes, like Ostwald ripening. The overall results show that hydrothermal synthesis of β-Ni(OH)2 in the presence of polymers with hydrophilic groups and surfactants is a versatile tool for crystal morphogenesis.
The structure of turbulent boundary layers (1967)

Extensive visual and quantitative studies of turbulent boundary layers are described. Visual studies reveal the presence of surprisingly well-organized spatially and temporally dependent motions within the so-called ‘laminar sublayer’. These motions lead to the formation of low-speed streaks in the region very near the wall. The streaks interact with the outer portions of the flow through a process of gradual ‘lift-up’, then sudden oscillation, bursting, and ejection. It is felt that these processes play a dominant role in the production of new turbulence and the transport of turbulence within the boundary layer on smooth walls. Quantitative data are presented providing an association of the observed structure features with the accepted ‘regions’ of the boundary layer in non-dimensional co-ordinates; these data include zero, negative and positive pressure gradients on smooth walls. Instantaneous spanwise velocity profiles for the inner layers are given, and dimensionless correlations for mean streak-spacing and break-up frequency are presented. Tentative mechanisms for formation and break-up of the low-speed streaks are proposed, and other evidence regarding the implications and importance of the streak structure in turbulent boundary layers is reviewed.
Designed synthesis of nanostructured siloxane–organic hybrids from amphiphilic silicon-based precursors (2006)

This paper reports on recent progress in the synthesis of nanostructured siloxane-organic hybrids based on the self-assembly of amphiphilic silicon-based precursors. A variety of ordered hybrid materials have been obtained by molecular design of the precursors. Alkoxysilanes and chlorosilanes with covalently attached hydrophobic organic tails are hydrolyzed to form amphiphilic molecules containing silanol groups, leading to the formation of layered (lamellar) structures. Transparent and oriented thin films of lamellar hybrids were prepared by the reaction in the presence of tetraalkoxysilane. In addition, the design of molecules having alkyl chains and large oligosiloxane heads led to the formation of mesophases consisting of cylindrical assemblies, providing a direct pathway to ordered porous silica. The synthesis, structural features, and formation processes of these hybrid mesostructures are discussed.
The Market for Electronic Cash Cards (2002)

We develop a theoretical framework aimed to model the pricing of electronic cash cards and the market domain in which these cards will be used in an environment where charge cards and currency (the legal tender) are competing payment media. We also investigate whether the adoption of the various payment media generates an underutilization or overutilization of the electronic cash cards relative to currency.
