Titanium and ruthenium binaphthyl Schiff base complexes as catalysts for asymmetric trimethylsilylcyanation of aldehydes (1999)

Investigations on the catalytic behaviour of titanium complexes formed in situ from Ti(OPri)4 and a variety of Schiff bases, mainly the binaphthyl derivatives 2,2′-bis(3-R1-5-R2-2-hydroxybenzylideneamino)-1,1′-binaphthyl, toward the asymmetric trimethylsilylcyanation of some aromatic and aliphatic aldehydes demonstrated that the titanium complex of the binaphthyl Schiff base with R1 = R2 = But is one of the best catalysts for such a process, with an enantiomeric excess (e.e.) as high as 96% obtained for m-tolualdehyde. Crystal structure determination of a nitrosylruthenium complex, [RuII(L)(NO)Cl] (L is the dianion of the binaphthyl Schiff base with R1 = R2 = Cl), revealed that the complex assumes a cis-β configuration with the binaphthyl moiety having a dihedral angle of 70.2°. After treatment with AgPF6, the ruthenium complex also exhibited a good catalytic property for the trimethylsilylcyanation of benzaldehyde albeit with a lower e.e. (24%).
The Burroughs integrated adaptive routing system (BIAS TM ) (1987)

The routing function used for Burroughs Network Architecture (BNA) to determine the best routes for traffic through the network is known as the BURROUGHS INTEGRATED ADAPTIVE ROUTING SYSTEM, or BIAS&amp;trade;.Based on the algorithm devised for the MERIT Computer Network [3], BIAS&amp;trade; is a decentralized, deterministic system which adapts to changes in network topology automatically. The current BIAS&amp;trade; routing architecture incorporates improvements in the original algorithm [1] which significantly reduce the recovery time from failures of network elements and is virtually loop-free, even during recovery from those failures.BIAS&amp;trade; automatically responds to the following changes to the network topology:- a node (an end system or intermediate system) is added to the network;- a node is removed from the network;- the cost of transiting a node is changed;- a logical link (LAN, leased or switched circuit, X.25 virtual circuit) is added to the network;- a link is removed from the network; and/or- the cost of transiting a link is changed;and re-determines the best route for all traffic throughout the network.
High throughput and parallel flow cytometer using microball lens integrated 3D microfluidic device (2017)

We report an ultrahigh throughput microflow cytometer which has 32 detection flow channels with 3D flow focusing for each channel. This flow cytometer is realized by integrating a high N.A. microball lens array with a 3D microfluidic device, which allows introducing cell samples into 32 sample channels. There are, 64 channels for sheath flow used for parallel lateral focusing and 32 sounding flows for parallel sounding focusing. All microchannels use only three inlets. Results show that a 95% yield rate by standard 10 μm bead detection has been achieved, and a throughput of 1,400,000 cell/sec has been accomplished on a single device.
Comparison of protein and peptide prefractionation methods for the shotgun proteomic analysis of Synechocystis sp. PCC 6803 (2005)

Proteome analysis by gel-free "shotgun" proteomics relies on the simplification of a peptide mixture before it is analyzed in a mass spectrometer. While separation on a reverse-phase (RP) liquid chromatographic column is widely employed, a variety of other methods have been used to fractionate both proteins and peptides before this step. We compared six different protein and peptide fractionation workflows, using Synechocystis sp. PCC 6803, a useful model cyanobacterium for potential exploitation to improve its production of hydrogen and other secondary metabolites. Pre-digestion protein separation was performed by strip-based isoelectric focusing, one-dimensional polyacrylamide gel electrophoresis, or weak anion exchange chromatography, while pre-RP peptide separation was accomplished by isoelectric focusing (IEF) or strong cation exchange chromatography. Peptides were identified using electrospray ionization quadrupole time of flight-tandem mass spectrometry. Mass spectrometry (MS) and tandem mass spectra were analyzed using ProID software employing both a single organism database and the entire NCBI non-redundant database, and a total of 776 proteins were identified using a stringent set of selection criteria. Method comparisons were made on the basis of the results obtained (number and types of proteins identified), as well as ease of use and other practical aspects. IEF-IEF protein and peptide fractionation prior to RP gave the best overall performance.
New Deposition Method at Low Temperature Using Active Species Derived from High Purity Ozone Gas and Ethylene Gas (2019)

We have succeeded in the formation of SiO2 and Al2O3 films at room temperature using a large amount of chemically active species produced after mixing high purity ozone gas and ethylene gas (OER) to be utilized in chemical vapor deposition process (OER-CVD) and atomic layer deposition process (OER-ALD), respectively. Although a SiO2 film was formed by OER-CVD at room temperature, it showed comparable characteristics to that conventionally formed at high temperature. The OER-CVD and the OER-ALD are expected to enable various kinds of oxide film deposition (e.g., TiO2, ZnO) at lower temperature.

Dissipation behaviour of YBa2Cu3Oxsingle crystals studied through magnetization and magnetization decay measurements (1993)

Hysteresis loop and magnetization decay measurements performed on a YBCO single crystal in the low temperature range (T less-than-or-equal-to 44 K) are presented.\n\nThe hysteresis loops show the typical behaviour observed in such kind of sample with the so called 'fishtail effect'.\n\nThe magnetization decays are analysed in terms of the collective creep theory and, in the explored temperature range, they indicate a very different behaviour of the sample at two relatively near magnetic field values (mu(o) H = 1.6 T and mu(o) H = 3.4 T) where the measurements were performed.

Organotin Phosphines, Arsines, Stibines, and Bismuthines: Starting Materials for New Catalysts (1976)

The preparation, properties, and reactions of organotin phosphines, arsines, stibines, and bismuthines are reviewed, and some newer results are described in detail. The title compounds react with some transition metal carbonyls to form organotin phosphine, arsine, stibine, and bismuthine substituted transition metal carbonyl complexes, which show unusual stability and may be useful homogeneous catalysts. The preparation and properties of some new systems for catalytical purposes are described: (1) organotin phosphines like (tert-4H9)2[CH3)2SnCl]P react with metal carbonyls to form the corresponding complexes LM(CO)n-1, which can be fixed on the surface of e.g., an aerosol by a strong Sn-O-Si bond; (2) pstyryl-substituted organotin phosphines can be synthesized. Transition metal complexes with these compounds as ligands can be copolymerized with olefins, yielding systematically synthesized polymeric organotin phosphine substituted transition metal carbonyl complexes.

An Analysis of an Electromagnetic Mold for the Continuous Casting of Nonferrous Metals (1981)

Electromagnetic molds are presently being used in the continuous casting of aluminum billets and slabs. Various theoretical models that can be used to predict electromagnetic pressure differentials and forces for this application are examined. Dimensionless pressure and force factors are first derived using a one-dimensional field model. These factors are then refined using a two-dimensional semi-infinite model. This latter model is also used to examine the effect that coil coupling has on the field strength, pressures and forces. Finally, the coupled circuit method is used to predict pressure distributions for an actual mold geometry, including the essential effect of the field shaping short-circuited turn (screen). The effect of varying the location of the inductor and screen is examined.

Reconfigurable SRAM Architecture With Spatial Voltage Scaling for Low Power Mobile Multimedia Applications (2009)

This paper presents a dynamically reconfigurable SRAM array for low-power mobile multimedia application. The proposed structure use a lower voltage for cells storing low-order bits and a nominal voltage for cells storing higher order bits. The architecture allows reconfigure the number of bits in the low-voltage mode to change the error characteristics of the array in run-time. Simulations in predictive 70 nm nodes show that the proposed array can obtain 45% savings in memory power with a marginal (~10%) reduction in image quality.
Autonomous Potential Oscillations in a PEM Fuel Cell with a Pt Anode under CO Poisoning (2011)

The behaviour of a PEMFC with Pt anode under CO poisoning was experimentally investigated. Especially, the possibility and conditions for the occurrence of autonomous potential oscillation in galvanostatic operation were analysed [1]. A specific experimental setup, consisting of a differential fuel cell in H2/H2operation, was used in order to eliminate the masking effect of the cathode and to avoid spatial distributions along the channel. In galvanostatic operation, potential oscillations were observed (Fig. 1). In a first measurement series, the influence of CO concentration on the behaviour of the oscillations was analysed. Higher CO concentrations were found to increase the oscillation frequency because of enhanced CO adsorption [2].\nIn a second measurement series, the influence of the cell temperature was investigated. By means of activation energy analysis, an unequal influence of the temperature on the oscillation frequency has been found for Pt catalyst (EA = 40.5±0.6 kJ mol-1) compared to the previously reported case at PtRu (EA = 60.9 kJ mol-1) [3].\nAdditionally, oscillations were found in H2/O2 operation, too. They occur if the anode over¬potential is forced to increase until the onset potential for CO oxidation is reached. Nevertheless, in technical fuel cells operated with passive loads, the anode overpotential does usually not reach such high values, because a large fraction of the voltage loss is caused by cathodic and ohmic losses.\nAs an additional side effect, an increase of the Tafel slope at ηA≈350mV was observed in some of the galvanostatic polarisation curves. Two hypotheses for the occurrence of a second Tafel slope were drawn: on the one hand, the Heyrovski mechanism could enhance hydrogen adsorption at higher overpotentials; on the other hand, spatial distributions of the overpotential could lead to local CO oxidation and with this to enhanced hydrogen oxidation in parts of the reactor (e.g. under the ribs, where CO transport could be diffusion limited).\nFinally, a model of Zhang and Datta [3], developed for PtRu and recently applied to PtPd [4], was adapted to fit the measurements. The adapted parameter set was compared to the original values and reasonable physical explanations for the adaptations were given. The main differences between Pt and PtRu were found to be a lower water dissociation constant and a lower CO oxidation constant.
Zip based monopole antenna for wearable communication systems (2012)

The first textile monopole antenna design based on a zip at 2.5GHz is presented. Return loss and radiation pattern measurements are used to characterize a manufactured prototype. The obtained bandwidth and radiation characteristics make the zip antenna proper to be used for WiFi applications in the band from 2.4GHz to 2.7GHz. In addition, this novel design exhibits the advantage of being easily tunable.
Frequency modulation stimulated Raman scattering scheme for real-time background correction with a single light source (2022)

A frequency modulation (FM) scheme for stimulated Raman scattering (SRS) is presented with a single fiber-based light source. Pulse-to-pulse wavelength-switching allows real-time subtraction of parasitic signals leaving only the resonant SRS signal with a noise reduction of up to 30 % compared to digital subtraction schemes, leading effectively to a contrast improvement by a factor of up to 8.3. The wide tuning range of the light source from 1500 cm<sup>-1</sup> to 3000 cm<sup>-1</sup> and the possibility to separately adjust the resonant and the nonresonant wavenumber for every specimen allow to investigate a variety of samples with high contrast and high signal-to-noise ratio, e. g., for medical diagnostics.
Structural orientation and electric polarization of polymers in stationary magnetic fields (2002)

Magnetic fields (MFs) of 100 to 500 kA/m were found to order magnetoanisotropic structural units in nonpolar polymer melts, e.g., polyethylene (PE). A temperature range and a threshold intensity of MF were observed when PE melt was partially ordered, i.e., when it was in a quasi-liquid-crystalline state. It is believed that thermomagnetic treatment of polymers in MFs can result in electrical polarization and formation of magnetoelectrets. A relationship is believed to exist between the polarization processes and the orientation of magnetoanisotropic macromolecules and aggregates in MFs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Locality-centric thread scheduling for bulk-synchronous programming models on CPU architectures (2015)

With heterogeneous computing on the rise, executing programs efficiently on different devices from a single source code has become increasingly important. OpenCL, having a bulk-synchronous programming model, has been proposed as a framework for writing such performance-portable programs. Execution order of work-items in a program is unconstrained except at barrier synchronization events, giving some freedom to an implementation when scheduling work-items between synchronization points. Many OpenCL (and CUDA) compilers have been designed for targeting multicore CPU architectures. However, scheduling work-items in prior work has been done with primary focus on correctness and vectorization. To the best of our knowledge, no existing implementations consider the impact of work-item scheduling on data locality. We propose an OpenCL compiler that performs data-locality-centric work-item scheduling. By analyzing the memory addresses accessed in loops within a kernel, our technique can make better decisions on how to schedule work-items to construct better memory access patterns, thereby improving performance. Our approach achieves geomean speedups of 3.32× over AMD's and 1.71 × over Intel's implementations on Parboil and Rodinia benchmarks.

Acidic and catalytic properties of aluminated mordenite zeolite: effect of extraframework aluminium (1996)

The nature of the extraframework aluminium generated in dealuminated mordenite by alumination with AlCl3 and its effect on acidity and catalytic activity have been studied. A series of mordenites with framework Si/Al atomic ratios between 11 and 220 was obtained by alumination of dealuminated mordenite and was characterized using atomic absorption spectrophotometry, IR spectroscopy, MAS NMR and reaction studies.Alumination below 873 K preferentially introduced Al atoms into the extraframework sites instead of into the framework sites, while alumination at 873 K and higher temperatures led to the incorporation of more Al into the framework. In all cases a significant portion of the extraframework Al species was not ion-exchangeable with an aqueous solution of NH4NO3 and was unobservable by 27Al MAS NMR, suggesting its lack of symmetry. IR studies with NH3 and pyridine probes demonstrated that the extraframework Al species acted as Lewis acid sites. The mordenite aluminated at 873 K showed a comparable specific activity to the parent and dealuminated mordenite for toluene disproportionation and o-xylene coversion as measured by turn-over frequency based on the number of Brønsted acid sites. Those aluminated below 873 K, however, exhibited enhanced specific activity for both reactions. The enhancement is explained by the Lewis acidic extraframework Al exhibiting electron-withdrawing properties and thus intensifying the Brønsted acidity of the framework Al.
Optimizing Partially Ordered Transport Services for Multimedia Applications. (1996)

References [1, 5] introduce a transport protocol... This paper investigates how much the selection of a linear extension affects system performance in a partially ordered service. We first show how to identify better linear extensions of a partial order, and then determine the performance gains by using such linear extensions at the time of transmission. To quantify linear extensions of a partial order, we propose a new metric (pBuf-metric) that is derived from buffering probabilities. Since pBuf-metric is complex to calculate, a simplified version called alpha-metric is also investigated. An OPNET simulation shows that for certain partial orders, a linear extension optimized according to these metrics provides some delay, and significant buffer utilization improvements over a non-optimal linear extension. Thus, prudent transmission order selection in a partially ordered service does improve system performance. Results also show that, in general, alpha-metric is as effective as pBu...
UV-C irradiation is highly effective in inactivating SARS-CoV-2 replication (2020)

The potential virucidal effects of UV-C irradiation on SARS-CoV-2 were experimentally evaluated for different illumination doses and virus concentrations (1000, 5, 0.05 MOI). At a virus density comparable to that observed in SARS-CoV-2 infection, an UV-C dose of just 3.7 mJ/cm 2 was sufficient to achieve a more than 3-log inactivation without any sign of viral replication. Moreover, a complete inactivation at all viral concentrations was observed with 16.9 mJ/cm 2 . These results could explain the epidemiological trends of COVID-19 and are important for the development of novel sterilizing methods to contain SARS-CoV-2 infection.

End Of Life: A Workplace Issue (2010)

Many employers have not placed a priority on addressing end-of-life issues. Yet these issues affect their employees who serve as caregivers to ailing parents and siblings, who experience a health crisis for themselves or a partner, or who care for a critically ill child. End-of life issues affect employers' cost of benefits, workers' productivity, and absentee and "presenteeism" rates, and they can undermine employees' effectiveness at work. Some employers have begun to address end-of-life issues with targeted programs and are gathering data to evaluate their impacts. Potential solutions include using existing resources; training managers to assist employees in need; and monitoring the costs of end-of-life challenges. In an environment where end-of-life issues are politically charged, employers must clearly communicate their motives to workers and assure them that end-of-life resources have beneficial intent.
Controlled growth of inorganic nanorod arrays using graphene nanodot seed layers (2014)

We report the density- and size-controlled growth of zinc oxide (ZnO) nanorod arrays on arbitrary substrates using reduced graphene oxide (rGO) nanodot arrays. For the controlled growth of the ZnO nanorod arrays, rGO nanodot arrays with tunable density and size were designed using a monolayer of diblock copolymer micelles and oxygen plasma etching. While the diameter and number density of the ZnO nanorods were readily determined by those of the rGO nanodots, the length of the ZnO nanorods was easily controlled by changing the growth time. x-ray diffraction and electron microscopy confirmed that the vertically well-aligned ZnO nanorod arrays were heteroepitaxially grown on the rGO nanodots. Strong, sharp near-band-edge emission peaks with no carbon-related peak were observed in the photoluminescence spectra, implying that the ZnO nanostructures grown on the rGO nanodots were of high optical quality and without carbon contamination. Our approach provides a general and rational route for heteroepitaxial growth of high-quality inorganic materials with tunable number density, size, and spatial arrangement on arbitrary substrates using rGO nanodot arrays.
