Physics-Based Modeling of Hole Inversion-Layer Mobility in Strained-SiGe-on-Insulator (2007)

The hole inversion-layer mobility of strained-SiGe homo- and heterostructure-on-insulator in ultrathin-body MOSFETs is modeled by a microscopic approach. The subband structure of the quasi-2-D hole gas is calculated by solving the 6times6koarrldrpoarr Schrodinger equation self-consistently with the electrostatic potential. The model includes four important scattering mechanisms: optical phonon scattering, acoustic phonon scattering, alloy scattering, and surface-roughness scattering. The model parameters are calibrated by matching the measured low-field mobility of two particularly selected long-channel pMOSFET cases. The calibrated model reproduces available channel-mobility measurements for many different strained-SiGe-on-insulator structures. For the silicon-on-insulator MOS structures with unstrained-Si channels, the silicon-thickness dependence resulting from our model for the low-field channel mobility agrees with previous publications.
Stability of Glutamine and Pyroglutamic Acid under Model System Conditions: Influence of Physical and Technological Factors (1987)

ABSTRACT The stability of glutamine and pyroglutamic acid as regards pH, temperature and oxygen was studied during storage and two thermal processings, the residual products and those which appeared being determined. Contrary to glutamic acid, the two derivatives are labile below pH 2 and above pH 13 and alteration occurs much faster. Temperature increase promotes this phenomenon. Glutamic and pyroglutamic acids convert reversibly into one another, more or less quickly and completely according to the conditions. Glutamine changes during heating in two steps, first into glutamic acid, then into pyroglutamic acid if the pH values are not extreme. The influence of pH conditions on the direction and the rate of the reaction are indicated.
CHR3: a <i>Caenorhabditis elegans</i> orphan nuclear hormone receptor required for proper epidermal development and molting (1998)

CHR3 is a Caenorhabditis elegans orphan nuclear hormone receptor highly homologous to Drosophila DHR3, an ecdysone-inducible gene product involved in metamorphosis. Related vertebrate factors include RORalpha/RZRalpha, RZRbeta and RevErb. Gel-shift studies show that CHR3 can bind the DR5-type hormone response sequence. CHR3 is a nuclear protein present in all blastomeres during early embryogenesis. During morphogenesis, both CHR3 protein and zygotically active reporter genes are detectable in epidermal cells and their precursors. Inhibition of the gene encoding CHR3 results in several larval defects associated with abnormal epidermal cell function, including molting and body size regulation, suggesting that CHR3 is an essential epidermal factor required for proper postembryonic development.
Corporate Disclosure of Material Information: The Evolution—and the Need to Evolve Again (2013)

This article by the former chairman of the FASB and the founder and executive director of the new Sustainability Accounting Standards Board (SASB) presents the rationale for and mission of the SASB. As the authors point out, both the Securities and Exchange Commission, which was created in 1934, and the Financial Accounting Standards Board, set up in 1973, emerged during times of low investor confidence to restore trust in the capital markets. And the institutional changes brought about by the creation of both the SEC and the FASB succeeded in eliciting new information for investors and in raising the standards by which such information was reported. But as the authors go on to argue, we now live in a different world, one in which the management of environmental, social, and governance issues is increasingly viewed as critical to the long‐run value creation of companies. And because today's corporate reporting fails to account in a systematic way for material non‐financial issues, it's time once again for the capital markets to evolve. The SASB aims to meet this need by creating sustainability accounting standards for use by public companies in disclosing a minimum set of material sustainability impacts for companies in over 80 different industries. As part of a natural evolution in disclosure, the SASB aims to achieve the same goal the SEC and FASB started with: to protect investors and the public.
Acoustic Wave Propagation In A Fluid-Filled Borehole With A Horizontal Fracture (1990)

The propagation of guided waves in a fluid-filled borehole with an open horizontal fracture is investigated both theoretically and experimentally. The fracture is modeled as a fluid layer that separates the domain of propagation into two regions. For the solution of the problem, we use a hybrid method to generate wave modes in the two regions. The modes are then summed to match the boundary conditions at the fracture surfaces. A singularity problem arises in matching the surface conditions and is regularized using a physical model based on the conservation of mass. Using the theory developed in this study, we study the transmission and reflection characteristics of borehole guided waves (Le., Stoneley and pseudo-Rayleigh waves) due to the fracture. At low frequencies, the effects of a fracture on the Stoneley wave are dominated by the fluid flow into the fracture. As frequency increases, mode conversion at the fracture becomes significant. Above the cut-off frequency of the pseudo-Rayleigh wave, part of the incident Stoneley wave is converted to pseudo-Rayleigh waves, which is demonstrated by synthetic microseismograms. The pseudo-Rayleigh wave is substantially affected by the fracture. Because this wave requires the formation shear strength to sustain its propagation, even a thin fracture with zero shear strength can significantly attenuate the wave amplitude and produce strong reflection. This effect is more pronounced towards the cut-off frequencies than away from the frequencies. Consequently, the lack of pseudo-Rayleigh energy across a fracture may be used as a sensitive indicator in fracture detection and characterization. Ultrasonic experiments have been performed to measure the transmission of guided waves across laboratory borehole fracture models. For the Stoneley waves, we performed the experiment below the cut-off frequency of the pseudo-Rayleigh wave and the experimental results are in good agreement with the theory. For the pseudo-Rayleigh wave, we performed the experiment in a higher frequency range. The experiment has verified the substantial effects of a fracture on this wave mode. The weak early arrivals of the transmitted waves have also been observed for thin as well as thick fractures. This confirms the theoretical prediction that the transmission of the pseudo-Rayleigh wave is the smallest towards the cut-off frequencies. The measured transmission coefficients agree with theoretical results. In summary, we have presented an analysis on the guided wave propagation across a borehole horizontal fracture. The wave characteristics in the vicinity of a fracture as described in this study may be used to provide useful information for the detection and characterization of borehole fractures using acoustic logging techniques.
Heritage and the Pandemic: An Early Response to the Restrictions of COVID-19 by the Heritage Sector in England (2020)

<p>This article examines the response of the English heritage sector, in particular Historic England, to the impact caused by the initial lockdown and restrictions introduced to protect lives during the COVID-19 pandemic in the UK. This response, headed by the Heritage Sector Response Group, relied on effective cross-sector working in order to both make the case for targeted support for the heritage sector to the UK Government and to provide advice and support for organisations during the lockdown and the limited reopening of the economy which followed. This included gathering intelligence in order to understand the impact of restrictions on the sector, which was used to swiftly develop emergency grant schemes funded by the Department for Digital, Culture, Media and Sport, the National Lottery Heritage Fund and Historic England. The paper also considers the Historic England Heritage Online Debate around the impact of COVID-19 restrictions on the sector, which gathered case studies from across the sector to capture and share qualitative information. The paper then looks at other long term challenges facing the sector, such as climate change, and considers how a collaborative approach and lessons learned from the sector’s response to the COVID-19 restrictions may provide models for building resilience for the future and developing solutions to other issues.</p>

On the utility of rate adaptation for broadcast/multicast media traffic in 802.11 networks (2009)

As there is no MAC layer acknowledgment from the receiver for broadcast/multicast transmission in the 802.11 network, using the lowest transmission rate is understandably the safest approach because it minimizes reception error for clients with the worst channel condition. On the contrary, the transmission rate for receivers with good channel conditions is unnecessarily limited. In the case of video streams being broadcast/multicast via 802.11, this approach will lead to poor received video at all clients.
Causes and Solutions of Recombination in Perovskite Solar Cells (2018)

Organic-inorganic hybrid perovskite materials are receiving increasing attention and becoming star materials on account of their unique and intriguing optical and electrical properties, such as high molar extinction coefficient, wide absorption spectrum, low excitonic binding energy, ambipolar carrier transport property, long carrier diffusion length, and high defects tolerance. Although a high power conversion efficiency (PCE) of up to 22.7% is certified for perovskite solar cells (PSCs), it is still far from the theoretical Shockley-Queisser limit efficiency (30.5%). Obviously, trap-assisted nonradiative (also called Shockley-Read-Hall, SRH) recombination in perovskite films and interface recombination should be mainly responsible for the above efficiency distance. Here, recent research advancements in suppressing bulk SRH recombination and interface recombination are systematically investigated. For reducing SRH recombination in the films, engineering perovskite composition, additives, dimensionality, grain orientation, nonstoichiometric approach, precursor solution, and post-treatment are explored. The focus herein is on the recombination at perovskite/electron-transporting material and perovskite/hole-transporting material interfaces in normal or inverted PSCs. Strategies for suppressing bulk and interface recombination are described. Additionally, the effect of trap-assisted nonradiative recombination on hysteresis and stability of PSCs is discussed. Finally, possible solutions and reasonable prospects for suppressing recombination losses are presented.
Overview of Septentrio's Galileo Receiver Development Strategy (2005)

ABSTRACT This paper contains an overview of our current and future Galileo-related projects, architecture and design choices for our line of Galileo receivers. Septentrio is developing Galileo receivers for various European projects: receivers intended for the testing of GSTB-V2, test user receivers intended for the in-orbit validation of all the Galileo services, and professional user receivers designed for high-precision RTK-based applications. The paper begins with a general overview of Galileo signal components and a list of Galileo user observables to be generated by future receivers. Because some signal components are supposed to be tracked co-operatively, the list of user observables is significantly shorter than the list of signal components. Further to this, we describe Septentrio’s Galileo-related receiver design projects, which include 3 major milestones: (i) GETR receiver, intended for in-orbit validation of Galileo signals transmitted by GSTB-V2 satellites; (ii) test user receiver (TUR), which shall be used to validate user requirements to the actual Galileo system; (iii) commercial Galileo/GPS receiver, intended for high-precision RTK applications. We pay particular attention to the GETR receiver (GETR stands for Galileo Experimental Test Receiver), already available at the time of this writing. The layout and the functionality of the new receiver are described and some early performance results are presented.
Indole Alkaloids from <i>Alocasia macrorrhiza</i> (2012)

Five new indole alkaloids, alocasins A-E (3-7), together with known hyrtiosin B (1) and hyrtiosulawesin (2) were isolated from Alocasia macrorrhiza (L.) SCHOTT; their structures were elucidated on the basis of spectroscopic data. Compounds 1-7 were in vitro tested for cytostatic activity on human throat cancer (Hep-2), human hepatocarcinoma (Hep-G2), and human nasopharyngeal carcinoma epithelial (CNE) cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method; compounds 2, 3, 6 and 7 showed mild antiproliferative activity against Hep-2 and Hep-G2 whereas compounds 2 and 4 showed gentle antiproliferative activity against CNE.
An intrastrain cross-reactive idiotype associated with anti-<i>p</i>-azophenylarsonate antibodies of BALB/c mice. (1981)

This paper describes an intrastrain cross-reactive idiotype, associated with the anti-Ar antibodies of all BALB/c mice tested. The idiotype is present on 20 to 65% of the anti-Ar antibodies of individual BALB/c mice and is localized to the Fab fragment. Adsorption of anti-Ar antibody from an immune serum completely removes the idiotypic activity. Inheritance of the idiotype is linked to the Igh locus, as shown by results obtained with congenic mice. It is present in strains that are Igh-Ia but not in the allotypically related Igh-Ij strains. The idiotype is also present in certain strains belonging to other allotype linkage groups. Expression of the idiotype is suppressed by the administration of rabbit antiidiotypic antibodies before immunization. The BALB/c idiotype is cross-reactive with an idiotype present in a small proportion of anti-Ar antibodies of A/J mice.
Hydraulic conductivity and consolidation response of mixtures of mine waste rock and tailings (2010)

Hydraulic conductivity and consolidation behaviour are examined for an alternative mine waste disposal technique. One type of waste rock, one type of tailings, and mixtures of the same waste rock and tailings were tested in bench-scale and column studies. Specimens 150 mm in diameter were tested for hydraulic conductivity by falling-head method alternated with one-dimensional consolidation, specimens 300 mm in diameter were tested for one-dimensional consolidation response, and specimens 1 m in diameter were tested for self-weight consolidation behaviour in 6 m high columns. Deformation of mixtures under one-dimensional loading was similar to that of waste rock alone and much less than that of tailings alone. Hydraulic conductivity of mixtures was similar to that of tailings alone and independent of specimen diameter. Mixture behaviour was attributed to a homogeneous structure including waste rock in particle-to-particle contact and a continuous, saturated matrix of tailings. The results indicate that mixing waste rock and tailings can produce dense deposits with values of hydraulic conductivity that are orders of magnitude lower than those of waste rock alone, thereby limiting fluxes through the waste and the associated potential for acid rock drainage. Mixture deposits will also have less consolidation-related settlement than tailings, thus improving stability and aiding reclamation.

Polarization reversal and thermally stimulated discharge current in a vinylidene fluoride trifluoroethylene copolymer (1991)

Polarization reversal in a ferroelectric copolymer of vinylidene fluoride and trifluoroethylene is observed in a circuit with a large time constant. The contributions of the ferroelectric and nonferroelectric phases in the copolymer can be identified in the reversal currents. If the copolymer is poled at high temperature, then reversal currents measured subsequently at lower temperatures display an asymmetry which is consistent with the accumulation of space charge in the copolymer. Shifts in successive reversal currents indicate that this space-charge accumulation dissipates slowly during polarization reversal. Thermally stimulated discharge currents from poled samples, and from samples with partially reversed polarization, indicate that there may be two populations of dipoles in the copolymer which are affected to different degrees by the space charge.

Social Network Analysis and Organizational Disintegration: The Case of Enron Corporation (2007)

Email networks in contemporary organizations are fairly representative of the underlying communications networks. We show that changes in communication networks have implications for studying organization disintegration. In this paper, we analyzed the changing communication network structure at Enron Corporation during the period of its disintegration (2000-2001). Our goal was to understand how communication patterns and structure were affected by organizational disintegration. Drawing on (social) network disintegration theory, we tested several propositions using the Enron email corpus: (1) Number of cliques increases (2) Communication network becomes increasingly centralized, and (3) Connectedness among the top management executives increases, as organizations move towards disintegration. The results of the tests and their implications are discussed.

Estimating the speaking rate by vowel detection (2002)

We present a new feature-based method for estimating the speaking rate by detecting vowels in continuous speech. The features used are the modified loudness and the zerocrossing rate which are both calculated in the standard preprocessing unit of our speech recognition system. As vowels in general correspond to syllable nuclei, the feature-based vowel rate is comparable to an estimate of the lexically-based syllable rate. The vowel detector presented is tested on the spontaneously spoken German Verbmobil task and is evaluated using manually transcribed data. The lowest vowel error rate (including insertions) on the defined test set is 22.72% on average over all vowels. Additionally correlation coefficients between our estimates and reference rates are calculated. These coefficients reach up to 0.796 and therefore are comparable to those for lexically-based measures (like the phone rate) on other tasks. The accuracy is sufficient to use our measurement for speaking rate adaptation.
EISI : An extensible security enterprise search system (2012)

In enterprise information search environment, sensitivity of data security, diversity of data source and data formats, search for database are especial problems. In view of security and extensibility, the architecture of an enterprise search system named EISI is proposed using metadata technology. The unified description model of heterogeneous information resources in enterprise is proposed for the management of search objects that is unstructured or structured, and the multi-level multi-granular security control is implemented based on the model. EISI is implemented by integrating existed index technology. EISI can adjust itself to the change of data source and data formats. The results of practical application indicate that both structured data and unstructured data can be searched in security, moreover the requirements of data search can be met effectively.
Approaches to the synthesis of immunolides: selective immunomodulatory macrolides for cystic fibrosis. (2005)

The discovery of the clinical effectiveness of erythromycin and azithromycin in inflammatory airway diseases has inspired the discovery and development of macrolides with selective immunomodulatory activity. Erythromycin degradation continues to be a source of novel macrolides with a variety of selective biological activities. New technologies for drug discovery based in the emerging field of combinatorial biosynthesis provide the medicinal chemist with novel approaches toward the discovery of novel macrolides. Recent efforts to integrate synthetic organic medicinal chemistry with combinatorial biosynthesis have expanded the number of techniques available for macrolide synthesis.
A data flow language for operating systems programming (1973)

This paper describes a graphical programming language based on the concept of pure data flow sequencing of computations. Programs in this language are constructed through function definition and composition, and are based on the primitive notions of iteration, recursion, conditional expression, data replication, aggregation and selection, and the usual arithmetic and logical operations. Various useful programming devices such as the DO loop and, surprisingly, the memory cell are defined in terms of these primitives. Programs in this language are determinate in operation unless indeterminism is explicitly introduced. The utility of this language for designing and implementing operating systems is discussed.
