Synthesis, Characterization, and Applicability of Neutral Polyhydroxy Phospholane Derivatives and Their Rhodium(I) Complexes for Reactions in Organic and Aqueous Media (2001)

Two different protocols for the preparation of water-soluble, enantiomerically pure polyhydroxybisphospholanes from acid-labile acetal and tert-butyldimethylsilyl-protected derivatives are reported. These procedures circumvent two of the commonly encountered limitations in the synthesis of these potentially important ligands: (a) formation of phosphonium salts from the highly basic phosphine under acidic conditions, and (b) the need to start with preformed, fully protected cationic metal complex. Thus, cationic Rh complexes of these ligands have been prepared in a separate step, and they have been found to be excellent catalysts for organic and aqueous phase hydrogenation of dehydroamino acids. The viability of catalyst recovery has been demonstrated in three different systems, including two cases where > 99% ee can be achieved under recycling conditions.
Morpheme-based feature-rich language models using Deep Neural Networks for LVCSR of Egyptian Arabic (2013)

Egyptian Arabic (EA) is a colloquial version of Arabic. It is a low-resource morphologically rich language that causes problems in Large Vocabulary Continuous Speech Recognition (LVCSR). Building LMs on morpheme level is considered a better choice to achieve higher lexical coverage and better LM probabilities. Another approach is to utilize information from additional features such as morphological tags. On the other hand, LMs based on Neural Networks (NNs) with a single hidden layer have shown superiority over the conventional n-gram LMs. Recently, Deep Neural Networks (DNNs) with multiple hidden layers have achieved better performance in various tasks. In this paper, we explore the use of feature-rich DNN-LMs, where the inputs to the network are a mixture of words and morphemes along with their features. Significant Word Error Rate (WER) reductions are achieved compared to the traditional word-based LMs.
SOURCE OF ALPHA PARTICLES COLLIMATED TO 35 $mu$ m. (1971)

decay is suggested as the probable mechanism generating the hot electrons. The backscattered light presents a broadband spectrum in the sub-half-harmonic region. This spectrum is limited by a sharp cut-off near 400 nm and by a spectral gap near the half-harmonic region. The half-harmonic spectrum is shown to be split into a red and a blue shifted peak. Effects of the self-generated magnetic fields and plasma temperature on Raman scattering and two-plasmon decay, respectively, are examined as possible mechanisms responsible for the splitting of the half-harmonic spectrum. Finally, a discussion of the effects of the coupling of Raman and Brillouin scattering on the Raman spectrum is presented with emphasis on the quarter critical region. This last mechanism is suggested to contribute to the splitting of the half-harmonic light.
The Thermal Stability of (CaTiO&lt;sub&gt;3&lt;/sub&gt;)1-x (Cr&lt;sub&gt;3/4&lt;/sub&gt;Fe&lt;sub&gt;5/4&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;x&lt;/sub&gt; Ceramic Composites in the Microwave Region (2016)

The thermal stability, structural and dielectric properties of the (CaTiO3)1-x(Cr3/4Fe5/4O3)x ceramic composites with x = 0, 0.1, 0.5, 0.9 and 1 have been examined in microwave region. The samples were produced via the solid-state reaction. The orthorhombic structural phase of CaTiO3 and trigonal structural phase of Cr3/4Fe5/4O3 were confirmed by the X-Ray Powder Diffraction (XRPD). The XRPD patterns for composites reveal the quantities of each original phase present. The infrared spectra of the samples reinforce this structural verification indicating no or minimal occurrence of unwanted reactions. The first sample (x = 0) and last sample (x = 1) in this series exhibit the maximum and the minimum of the relative dielectric permittivity and values range from 140.1 to 8.3 respectively. The measured temperature coefficient of the matrix CaTiO3 was +921 ppm·℃-1 and for the matrix Cr3/4Fe5/4O3 was -56 ppm·℃-1. With the study of series of composites, it was possible to make a mathematical prediction for a composition reach the temperature coefficient near zero. The proposed ceramic has potential use as thermostable material in the microwave region and can be applied to resonators, low-noise amplifiers, filters, and so on.

Earcon blood pressure displays: Comparisons between auditory and visual BP display usability in an operating theatre context (2007)

Despite the known effectiveness of earcon auditory Blood Pressure (BP) displays, when used in laboratory settings by non-clinicians (Watson & Gill, 2004), their reliability and timeliness, in terms of user detection and response, have not yet been compared directly with that of visual BP displays. The aim of this study was to establish which BP display modality (auditory or visual) would be most effective in a dual task paradigm simulated operating theatre context. Eighteen undergraduate students participated in a repeated measures design study. Objective user performance and subjective user experience DV measures were compared after manipulating the IV, BP display modality, to be in either a cross-modal (auditory BP display and visual display secondary task), or intra-modal (visual BP display and visual display secondary task) dual-task condition. Confirming Wicken's (2002) Multiple Resource Theory and supportive of objective user performance predictions, BP monitoring was superior for the earcons (compared to visual BP) in terms of BP display update detection and response reliability and timeliness. Subjective user experience predictions were mostly supported (for certain performance criteria) as participants' perceived the earcons, compared to visual BP, as: less difficult to use; the most preferred display modality; and (judged alone) had high, as opposed to low, levels of usefulness. Appropriately designed displays that take advantage of different modalities may facilitate superior clinician awareness of a patient's physiological vital signs without causing a major shift in attention away from critical and concurrent tasks.

The loss of higher frequencies due to the filtering effect of the earth (attenuation), and the impossibility to fully recover those frequencies during the processing stages severely affect our ability to vertically separate events in our seismic sections as continuous individual reflectors below the tuning frequency. Seismic resolution is paramount for looking at stratigraphic features that indicate internal bedding geometries, pinch outs and reflector terminations all that often fall close to or below the limit of seismic resolution. In this paper we illustrate several techniques such as Frequency Analysis, Wavelet Geometry Analysis and Spectral Enhancement, which help identify thin beds and aid the interpretation of their extents in poorly resolved data.

Theoretical Analysis of AlAs₀.₅₆Sb₀.₄₄ Single Photon Avalanche Diodes With High Breakdown Probability (2021)

Single photon avalanche diodes (SPADs) are key enabling technologies for a wide range of applications in the near-infrared wavelength range. Recently, AlAs <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.56</sub> Sb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.44</sub> (hereafter AlAsSb) lattice-matched to InP has been demonstrated for extremely low excess noise avalanche photodiodes (APDs) due to its large disparity between electron and hole ionization coefficients ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula> and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula> respectively). The <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\alpha /\beta $ </tex-math></inline-formula> ratio also plays a role in Geiger mode operation as it affects the avalanche breakdown probability and hence detection efficiency. In this work, we theoretically investigate the performance of AlAsSb based SPADs. The probability of breakdown for electron-initiated Geiger mode operation increases more sharply with multiplication region width due to progressively more dissimilar ionization coefficients. In comparison with other common avalanche materials, such as InAlAs, InP and Si, our result also suggests that SPADs based on AlAsSb have a sharper breakdown probability than the other three materials under similar low overbias ratio. The calculated breakdown probability of 0.81 in AlAsSb is 0.18 and 0.28 higher than that of InAlAs/Si and InP respectively at 5% overbias ratio and with avalanche region width of 1500 nm.
The Impact of the Privacy Rule on Cancer Research: Variations in Attitudes and Application of Regulatory Standards (2009)

ASCO believes that disagreements related to compliance and the resulting delays in certain projects and abandonment of others might be eased by additional institutional training programs and consultation on Privacy Rule issues during study design. ASCO also proposes the development of best practices documents to guide 1) creation of data repositories, 2) disclosure and use of data from such repositories, and 3) the design of survivorship and genetics studies.
The influence of Ni stability, redox, and lattice oxygen capacity on catalytic hydrogen production via methane dry reforming in innovative metal oxide systems (2023)

Abstract Finding a robust catalytic system for hydrogen production via dry reforming of methane (DRM) remains a challenge. Herein, MNi 0.9 Zr 1 − x Y x O 3 (M = Ce, La, and La 0.6 Ce 0.4 ; x = 0.00, 0.05, 0.07, and 0.09) catalyst was prepared by the sol–gel method, tested for DRM and characterized by surface area and porosity, X‐ray diffraction, H 2 ‐temperature programmed reduction, thermogravimetry, and transmission electron microscopy. In La 0.6 Ce 0.4 NiO 3 catalyst, the substitution of Ni by 0.1% Zr results in a constant high catalytic activity (83% hydrogen yield at 800°C) due to the presence of reducible “NiO‐species interacted strongly with the support” (stable metallic Ni over reduced catalyst) and redox input by ceria phase for laying instant lattice oxygen during lag‐off period of CO 2 . Substitution of Ni by Zr and Y in the CeNiO 3 catalyst system nurtures Ni 3 Y (providing highly stable metallic Ni for CH 4 decomposition) and cerium yttrium oxide phases (providing strong redox input). CeNi 0.9 Zr 0.01 Y 0.09 O 3 shows 85% H 2 yield at 800°C.

Evolutionary Optimisation Methods for Template Based Image Registration (2007)

This paper investigates the use of evolutionary optimisation techniques to register a template with a scene image. An error function is created to measure the correspondence of the template to the image. The problem presented here is to optimise the horizontal, vertical and scaling parameters that register the template with the scene. The Genetic Algorithm, Simulated Annealing and Particle Swarm Optimisations are compared to a Nelder-Mead Simplex optimisation with starting points chosen in a pre-processing stage. The paper investigates the precision and accuracy of each method and shows that all four methods perform favourably for image registration. SA is the most precise, GA is the most accurate. PSO is a good mix of both and the Simplex method returns local minima the most. A pre-processing stage should be investigated for the evolutionary methods in order to improve performance. Discrete versions of the optimisation methods should be investigated to further improve computational performance.

Modelling and Control of a Heavy-Duty Diesel Engine Gas Path with Gaussian Process Regression (2019)

This paper presents a method for modelling and controlling charge air pressure of a heavy-duty Diesel engine. The modelling method combines expert information about the system with a training dataset to provide a reasonable extrapolation behaviour as well as high accuracy. The dynamics of the gas path are modelled as a Wiener process with separate dynamics for each input. After identifying these dynamics, a controller based on input-output linearisation can be designed. The controller is shown to be able to track a set point of the gas path even after a sensor failure. To this end, the system behaviour is learned online to increase the accuracy. An evaluation against a reference model shows the performance of the method.
Supramolecular Explorations: Exhibiting the Extent of Extended Cationic Cyclophanes (2016)

Acting as hosts, cationic cyclophanes, consisting of π-electron-poor bipyridinium units, are capable of entering into strong donor-acceptor interactions to form host-guest complexes with various guests when the size and electronic constitution are appropriately matched. A synthetic protocol has been developed that utilizes catalytic quantities of tetrabutylammonium iodide to make a wide variety of cationic pyridinium-based cyclophanes in a quick and easy manner. Members of this class of cationic cyclophanes with boxlike geometries, dubbed Ex(n)Boxm(4+) for short, have been prepared by altering a number of variables: (i) n, the number of "horizontal" p-phenylene spacers between adjoining pyridinium units, to modulate the "length" of the cavity; (ii) m, the number of "vertical" p-phenylene spacers, to modulate the "width" of the cavity; and (iii) the aromatic linkers, namely, 1,4-di- and 1,3,5-trisubstituted units for the construction of macrocycles (ExBoxes) and macrobicycles (ExCages), respectively. This Account serves as an exploration of the properties that emerge from these structural modifications of the pyridinium-based hosts, coupled with a call for further investigation into the wealth of properties inherent in this class of compounds. By variation of only the aforementioned components, the role of these cationic receptors covers ground that spans (i) synthetic methodology, (ii) extraction and sequestration, (iii) catalysis, (iv) molecular electronics, (v) physical organic chemistry, and (vi) supramolecular chemistry. Ex(1)Box(4+) (or simply ExBox(4+)) has been shown to be a multipurpose receptor capable of binding a wide range of polycyclic aromatic hydrocarbons (PAHs), while also being a suitable component in switchable mechanically interlocked molecules. Additionally, the electronic properties of some host-guest complexes allow the development of artificial photosystems. Ex(2)Box(4+) boasts the ability to bind both π-electron-rich and -poor aromatic guests in different binding sites located within the same cavity. ExBox2(4+) forms complexes with C60 in which discrete arrays of aligned fullerenes result in single cocrystals, leading to improved material conductivities. When the substitution pattern of the Ex(n)Box(4+) series is changed to 1,3,5-trisubstituted benzenoid cores, the hexacationic cagelike compound, termed ExCage(6+), exhibits different kinetics of complexation with guests of varying sizes-a veritable playground for physical organic chemists. The organization of functionality with respect to structure becomes valuable as the number of analogues continues to grow. With each of these minor structural modifications, a wealth of properties emerge, begging the question as to what discoveries await and what properties will be realized with the continued exploration of this area of supramolecular chemistry based on a unique class of receptor molecules.
Anti-Jahn-Teller Polaron (1998)

Distortions of the oxygen sublattice couple to $e_g$ orbitals of Mn$^{3+}$ and drive a cooperative Jahn-Teller (orbital ordering) transition in LaMnO$_3$. A simple model for this transition is studied. Without further adjustment, the model predicts the shape and stability of small (anti-Jahn-Teller) polarons which form when holes are doped into the material. This leads to a new description of the lightly doped insulator, the anti-ferromagnetic to ferromagnetic transition, and the metal-insulator transition.
Characteristics of liver injury in cases of COVID-19 (2021)

In novel coronavirus disease 2019 (COVID-19), liver injury was found at a high rate, and reports from outside Japan revealed that such injury was related to severity. We examined the characteristics of liver injury in 15 cases of COVID-19. Thirteen of these patients received antiviral therapy, such as favipiravir, remdesivir, and hydroxychloroquine. Liver injury was observed in eight cases at admission for COVID-19. The hepatic CT attenuation values at admission were significantly lower in nine patients who developed liver damage or showed its exacerbation during the treatment than in the remaining patients. Drug-induced liver injury due to antiviral drug was suspected in six cases. Liver injury due to COVID-19 may be related to low hepatic CT attenuation values and be modified by antiviral drugs.

Distributed video coding: A promising solution for distributed wireless video sensors or not? (2011)

Low-power and low-cost distributed wireless video sensors play important roles for applications in machine-to-machine (M2M) and wireless sensor networks. Distributed video coding (DVC), an emerging coding technology based on Wyner-Ziv theory, seems to be a possible solution for implementing low-power video sensors since most of the computational complexity is moved from the encoder to the decoder. In this paper, existing works on DVC are discussed with rate-distortion and power consumption analyses compared with H.264/AVC-based approaches. We show that, since more transmission power is required for compensating the lower rate-distortion performance, the power consumption of sensor nodes using DVC is just similar to that of using H.264/AVC with zero motion vectors. Therefore, there is still a room for improvement to make DVC applicable for distributed wireless video sensors. Based on our analysis results, several possible research directions, such as studies on the trade- off between hardware cost and system power consumption, are also addressed in this paper under a unified DVC framework.
Characterization of Monoclonal Antibodies against Human Leukocyte Common Antigen (CD45) (2011)

Induction of lupus inclusions by sera from patients with systemic lupus erythematosus (1986)

A sensitive in vitro bioassay for the alpha-interferon induction of lupus-type inclusions (LI) has been established with the human B lymphoblastoid cell line, Daudi. Sera from 11 patients with systemic lupus erythematosus (SLE) were evaluated with this assay. LI induction by these sera increased in proportion to their antiviral activity on Madin-Darby bovine kidney (MDBK) cells. Two of these sera did not induce LI; they showed no antiviral activity on the MDBK cell assay. Clinically and serologically, their donors were in remission. Two sera induced the formation of LI that exceeded the maximum frequencies obtained with 3 alpha-interferon preparations. These sera had the greatest antiviral activities, and their donors had the greatest disease activities. Antisera to alpha-interferons prevented the induction of LI with the pure and homogeneous recombinant human leukocyte interferon, IFLrA, and SLE sera. Together, these results provide evidence that the alpha-interferon endogenous to SLE patients has a great ability to induce LI, and the SLE serum induction of LI corresponds well to the patient's disease activity.
A Generic Framework for Target-Specific Transformation Operators in XML Transformation Languages (2007)

A key issue in exchanging XML-based data is their transformation. However, available transformation languages are generally still low-level. Their low-level transformation operators do not reflect the target language concepts and terminologies. Moreover, transformation correctness is usually beyond the scope of such operators. This paper presents a generic framework which offers higher-level transformation operators. Since it allows to express the transformation operators on the specific target languages level, the developer can more easily understand, validate, and modify the transformation. Based on a given XML schema of the target XML language, the necessary level transformation definitions are generated by the framework. In addition, transformation constraints are taken into consideration; besides transformation corresponding validation components are constructed. A showcase demonstrates how to generate the required components for BPEL- specific transformation operators and how to use them in XSLT.
