Zur Kenntnis der nickel‐katalysierten Mischoligomerisation von Butadien mit Hydrazonen. Vorläufige Mitteilung (1977)

Studies on the nickel‐catalysed reaction of butadiene with hydrazones The nickel‐catalysed reaction of butadiene with methyl‐hydrazones yields a series of isomeric azo‐compounds identified as 2:1 adducts. The products are compared with those of the analogous reaction of butadiene with imines (cf. Scheme 1–3 ).
Optimizing memory transactions (2006)

Atomic blocks allow programmers to delimit sections of code as 'atomic', leaving the language's implementation to enforce atomicity. Existing work has shown how to implement atomic blocks over word-based transactional memory that provides scalable multi-processor performance without requiring changes to the basic structure of objects in the heap. However, these implementations perform poorly because they interpose on all accesses to shared memory in the atomic block, redirecting updates to a thread-private log which must be searched by reads in the block and later reconciled with the heap when leaving the block.This paper takes a four-pronged approach to improving performance: (1) we introduce a new 'direct access' implementation that avoids searching thread-private logs, (2) we develop compiler optimizations to reduce the amount of logging (e.g. when a thread accesses the same data repeatedly in an atomic block), (3) we use runtime filtering to detect duplicate log entries that are missed statically, and (4) we present a series of GC-time techniques to compact the logs generated by long-running atomic blocks.Our implementation supports short-running scalable concurrent benchmarks with less than 50\% overhead over a non-thread-safe baseline. We support long atomic blocks containing millions of shared memory accesses with a 2.5-4.5x slowdown.
Magnetic field dependence of the thermoelectric power of superconducting Bi-Sr-Ca-Cu-O (1989)

Measurements of the temperature and magnetic field dependence of the thermopower S(B,T) are presented for a polycrystalline sample of the T\ensuremath{\sim}85 K phase of Bi-Sr-Ca-Cu-O. Between 90 and 140 K, S(B,T) is positive and shows a small decrease with increasing temperature. In this temperature interval the application of an external magnetic field does not influence S(B,T). Below 90 K, S(0,T) drops sharply at the superconducting transition temperature. The magnetic field B causes a suppression of the transition temperature similar to the effect observed in resistivity data. The field data are interpreted in terms of the Abrikosov vortex lattice for the mixed state of the type-II superconductor. Relating the thermopower to the transport entropy of the vortex motion due to the temperature gradient across the sample, we find that the sign of the charge carriers is positive, and the principal unit \ensuremath{\Elzxh}/2m of the particle flux is within 13% of its tabulated value.
Coordinated modular functionality and prognostic potential of a heart failure biomarker-driven interaction network (2010)

The identification of potentially relevant biomarkers and a deeper understanding of molecular mechanisms related to heart failure (HF) development can be enhanced by the implementation of biological network-based analyses. To support these efforts, here we report a global network of protein-protein interactions (PPIs) relevant to HF, which was characterized through integrative bioinformatic analyses of multiple sources of "omic" information. We found that the structural and functional architecture of this PPI network is highly modular. These network modules can be assigned to specialized processes, specific cellular regions and their functional roles tend to partially overlap. Our results suggest that HF biomarkers may be defined as key coordinators of intra- and inter-module communication. Putative biomarkers can, in general, be distinguished as "information traffic" mediators within this network. The top high traffic proteins are encoded by genes that are not highly differentially expressed across HF and non-HF patients. Nevertheless, we present evidence that the integration of expression patterns from high traffic genes may support accurate prediction of HF. We quantitatively demonstrate that intra- and inter-module functional activity may be controlled by a family of transcription factors known to be associated with the prevention of hypertrophy. The systems-driven analysis reported here provides the basis for the identification of potentially novel biomarkers and understanding HF-related mechanisms in a more comprehensive and integrated way.
Broadband NIR photoluminescence from Ni2+-doped nanocrystalline Ba–Al titanate glass ceramics (2011)

Nanocrystalline Ba–Al titanate precipitates from supercooled TiO2–BaO–SiO2–Al2O3 melts by catalyzed volume nucleation in the presence of Ni2+, forming a BaAl2Ti6O16 hollandite-type lattice. Ni2+-species are incorporated into the crystalline environment in octahedral coordination. Hollandite formation is accompanied by precipitation of tetrahedrally distorted BaTiO3 as a secondary crystal phase, where crystal species and habitus can be clearly distinguished by dark-field transmission electron microscopy. Resulting photoluminescence due to spin-allowed relaxation of 3T2g(3F) to 3A2g(3F) in VINi2+ occurs from three distinct emission centers. It spans the spectral range of 1.0 to 1.6 μm and exhibits a lifetime of about 60 μs, which suggests applications in tunable lasers and broadband optical amplifiers. Besides red and IR laser excitation, NIR photoemission can be excited with conventional near UV light sources, i.e. in the spectral range of 350–420 nm. Decay kinetics as well as position and shape of the emission band can be adjusted by dopant concentration and synthesis conditions.
Effects of a Conducting Wall on Z-Pinch Stability (2014)

The stabilizing effect of a conducting wall on Z-pinch stability has been investigated through a systematic experimental and numerical study. Numerical simulations of a Z-pinch with a cylindrical conducting wall are compared with a case that modeled perforations in the conducting wall. The conducting wall also acts as the return current path for these investigations. Plasma conditions with various pinch sizes were studied numerically to better understand the effect of wall stabilization in Z-pinches. A study using the ZaP Flow Z-Pinch was performed by inserting a 0.35-m perforated section of electrode that has eight longitudinal slots cut from the outer electrode, reducing the conducting wall material by ≈70% .This modification prevents currents from flowing freely along the azimuthal distance of the outer electrode required to stabilize the m = 1, 2, 3 modes, which are experimentally monitored. Operating with identical experimental parameters with and without the perforated electrode was assumed to produce similar equilibrium and flow shear conditions in the pinch. Comparing the stability characteristics isolated the potential effects of the conducting wall. Magnetic data, interferometry, and optical images indicate that the conducting wall does not have a discernible effect on stability in the ZaP experiment. This result agrees with simulations with similar ratios of conducting wall radius to pinch radius.
PROGRESS ON MUON PARAMETRIC-RESONANCE IONIZATION COOLING CHANNEL DEVELOPMENT* (2012)

Parametric-resonance Ionization Cooling (PIC) is intended as the final 6D cooling stage of a high- luminosity muon collider. To implement PIC, a continuous-field twin-helix magnetic channel with a correlated behavior of the horizontal and vertical betatron motions and dispersion was developed. A 6D cooling with stochastic effects off is demonstrated in a GEANT4/� G4beamline model of a system where wedge- shaped Be absorbers are placed at the appropriate dispersion points in the twin-helix channel and are followed by short rf cavities. To proceed to cooling simulations with stochastics on, compensation of the beam aberrations from one absorber to another is required. Initial results on aberration compensation using a set of various-order continuous multipole fields are presented. As another avenue to mitigate the aberration effect, we optimize the cooling channel's period length. We observe a parasitic parametric resonance naturally occurring in the channel's horizontal plane due to the periodic beam energy modulation caused by the absorbers and rf. We discuss options for compensating this resonance and/or properly combining it with the induced half-integer parametric resonance needed for PIC.
Sammenhengen mellom arealbruk i jordbrukslandskapet og tilstedeværelse av fuglearter (2017)

Intensivt jordbruk eller brakklegging av jordbruksareal blir ofte omtalt som de viktigste årsakene til nedgangen i kulturlandskapsarter av fugl i Europa. Dette er arter der mer enn halvparten av hekkebestanden finnes i jordbrukslandskapet. I denne studien viser vi en positiv sammenheng mellom både artsrikdom og tetthet av fuglearter knyttet til kulturlandskapet og mengde jordbruksareal i landskapet. Variasjon er derimot viktig. Vi fant nemlig også at det er uheldig med store sammenhengende jordbruksarealer. Variasjon i arealbruk og innslag av naturlig vegetasjon i landskapet er viktig for kulturlandskapsfugler og for andre arter, slik at landskapet ikke blir for ensartet. Dette gir høyest mulig artsmangfold av fugler.
Designing a Software-Defined Datacenter (2014)

A datacenter is a complex environment, which consists of network equipment, server hardware and storage systems. Traditionally these are managed by system administrators or infrastructure engineers, either manually or by scripting. Cloud computing has pushed this traditional model more into automation-based solutions. Servers and services are expected to be provisioned as fast as possible, usually within minutes.&#13;\nThis thesis examines how a datacenter can be designed to enable fast, reliable and scalable automation. It also has to provide certain high-availability and scalability features, such as virtual machine migration. A multi-vendor environment is expected, but all components must support centralized management. The infrastructure has to provide different APIs (Application Programming Interface) in all components of the datacenter. A datacenter which can be controlled by utilizing these APIs can be called as a softwaredefined datacenter.&#13;\nAn implementation of a software-defined datacenter is presented. The datacenter is based on VMware virtualization, Hewlett-Packard server hardware, NetApp storage with Hewlett-Packard and Cisco networking equipment. A virtualization environment was installed and configured by using features that helped mass-configuration. An orchestration tool was installed, which is the key building block for providing flexible automation workflows. An orchestration workflow was designed to provide customizable virtual machine provisioning, DNS configuration, storage allocation and network configuration.&#13;\nAdditional ideas for improvement are also introduced. These topics include environment upgrades and security patching, IPv6 deployment and automated configuration management. Configuration management is the next step in infrastructure automation, as it enables operating system configuration automation. It is dependent of the infrastructure automation, such as server provisioning, presented in this thesis.&#13;\nThe implementation proves that it is possible to build a software-defined datacenter with multi-vendor hardware. All components, however, must some how support automation or provide an API. The same implementation presented in this thesis could be achieved by different components by different vendors, including hardware and virtualization layer.
Recognition of PD mode based on KNN algorithm for converter transformer (2013)

A kind of fault diagnosis method based on KNN(K-Nearest Neighbour) is proposed for converter transformer.Four types of artificial oilpaper insulation defect are designed and the UHF(Ultra High Frequency) antenna is used to collect PD(Partial Discharge) UHF signals.Multi-scale wavelet packet transform is carried out for calculating the energy coefficients of collected PD UHF signals and the KNN algorithm is applied to recognize their characteristic parameters.The PD mode recognized by the BPNN(Back Propagation Neural Network) is compared with that by the proposed algorithm,which shows that the latter is more suitable for the fault diagnosis of converter transformer.
Genome, secretome and glucose transport highlight unique features of the protein production host Pichia pastoris (2009)

This work highlights significant advantages of using the P. pastoris system with glucose based expression and fermentation strategies. As only few proteins and no proteases are actually secreted on glucose, it becomes evident that cell lysis is the relevant cause of proteolytic degradation of secreted proteins. The endowment with hexose transporters, dominantly of the high affinity type, limits glucose uptake rates and thus overflow metabolism as observed in S. cerevisiae. The presence of 4 genes for glycerol transporters explains the high specific growth rates on this substrate and underlines the suitability of a glycerol/glucose based fermentation strategy. Furthermore, we present an open access web based genome browser http://www.pichiagenome.org.

Optoelectronic Sensors based on OLED-on-CMOS (2008)

Highly-efficient, low-voltage organic light emitting diodes (OLED) are well suitable for post-processing integration onto the top metal layer of CMOS devices. The use of OLED on CMOS substrates requires a top-emitting, low-voltage and highly efficient OLED structure. So far OLED-on-CMOS application has been limited to microdisplays only. By the use of integrated photodetectors, low-cost CMOS processes and simple packaging, new optoelectronic microsystems with combined sensors and actuating elements can be realized. They can be used for optical integrated circuits (OIC's), for fiber optics, to measure temperature, distance or fill level as well as to transfuse optical signals (optocoupler, optical data communication). Furthermore they can be used for applications which react to failures in optical paths (light barriers) or to capture physical properties of objects by reflection of light (colour-, flow-, contrastor luminescence sensors). We developed an optical microsystem with three different types of sensors: a color, flow and reflection sensor. A corresponding demonstrator shows the functionality of combined sensors and actuating elements based on OLED and CMOS integration. The silicon chip was manufactured in a commercial 1micrometer CMOS technology. The integration of the OLED's takes place in the production line of the IPMS.
Impact of soft open point on feeder automation (2016)

Soft open points (SOPs) are power electronic devices installed in place of normally open points in distribution networks. SOPs are implemented using back-to-back voltage source converters (VSCs), which allows independent control of real and reactive power flowing through their AC terminals. This paper studies the impact of using SOPs on an existing feeder automation scheme under balanced fault conditions. The operation of the network without an SOP is used as a base case for comparison. Simulations were carried out on a network model developed in the EMTDC/PSCAD simulation platform. An algorithm for the control of the SOP is proposed. It uses error suppressor and voltage-frequency droop control to ensure that the SOP does not contribute to the fault. Simulation results show that the SOP can perform adequately without interrupting the sequence of operation in the existing feeder automation scheme and, in addition, can continue to provide reactive power support to an unfaulted feeder.
Beyond genetics: childhood affective trauma in bipolar disorder (2008)

Childhood trauma is associated with bipolar disorder and its clinical expression and may interact with genetic susceptibility factors. Although not completely understood, the relationships between childhood trauma and bipolar disorder require further attention. Several suggestions for further exploration of this environmental factor and of its interaction with susceptibility genes are proposed.
Bubble Dynamics and Cavitation (1977)

The first analysis of a problem in cavitation and bubble dynamics was made by Rayleigh (1917), who solved the problem of the collapse of an empty cavity in a large mass of liquid. Rayleigh also considered in this same paper the problem of a gas-filled cavity under the assumption that the gas undergoes isothermal com­ pression. His interest in these problems presumably arose from concern with cavitation and cavitation damage. With neglect of surface tension and liquid viscosity and with the assumption of liquid incompressibility, Rayleigh showed from the momentum equation that the bubble boundary R(t) obeyed the relation RR+W<)2 = p(R)oo, p (1.1)

Thermoelectric Seebeck effect in oxide-based resistive switching memory (2014)

Reversible resistive switching induced by an electric field in oxide-based resistive switching memory shows a promising application in future information storage and processing. It is believed that there are some local conductive filaments formed and ruptured in the resistive switching process. However, as a fundamental question, how electron transports in the formed conductive filament is still under debate due to the difficulty to directly characterize its physical and electrical properties. Here we investigate the intrinsic electronic transport mechanism in such conductive filament by measuring thermoelectric Seebeck effects. We show that the small-polaron hopping model can well describe the electronic transport process for all resistance states, although the corresponding temperature-dependent resistance behaviours are contrary. Moreover, at low resistance states, we observe a clear semiconductor-metal transition around 150 K. These results provide insight in understanding resistive switching process and establish a basic framework for modelling resistive switching behaviour.
NACK Is an Integral Component of the Notch Transcriptional Activation Complex and Is Critical for Development and Tumorigenesis (2014)

The Notch signaling pathway governs many distinct cellular processes by regulating transcriptional programs. The transcriptional response initiated by Notch is highly cell context dependent, indicating that multiple factors influence Notch target gene selection and activity. However, the mechanism by which Notch drives target gene transcription is not well understood. Herein, we identify and characterize a novel Notch-interacting protein, Notch activation complex kinase (NACK), which acts as a Notch transcriptional coactivator. We show that NACK associates with the Notch transcriptional activation complex on DNA, mediates Notch transcriptional activity, and is required for Notch-mediated tumorigenesis. We demonstrate that Notch1 and NACK are coexpressed during mouse development and that homozygous loss of NACK is embryonic lethal. Finally, we show that NACK is also a Notch target gene, establishing a feed-forward loop. Thus, our data indicate that NACK is a key component of the Notch transcriptional complex and is an essential regulator of Notch-mediated tumorigenesis and development.
A Novel Energy Management Control Technique for PV-Battery System in DC Microgrids (2021)

This paper presents a new energy management control technique for PV-Battery system used in DC microgrids. The proposed control technique is performed based on a droop control algorithm that maintains DC-bus voltage in a desirable and required range adaptively. Tightly Regulating the bus voltage In the islanded mode of operation is very challenging. However, the proposed control method by introducing a nonlinear droop profile with four adaptive parameters shows its superiority. Adaptive parameters determined by the non-linear optimal algorithms. Tightly regulating the DC bus voltage during extensive changes in demand loads/sources within a DC Micro Grid is the responsibility of the adaptive parameters. Stability of the proposed method in the whole system for a very broad range of operating conditions are proved. Simulation results along with the experimental results verify the feasibility of the proposed approach while demonstrate its superior performance compared to the conventional control method.
A design by example regular structure generator (1985)

This paper investigates technical issues concerning the automated generation of highly regular VLSI circuit layouts (e.g. RAMs, PLAs, systolic arrays) that are crucial to the designability and realizability of large VLSI systems. The key is to determine the most profitable level of abstraction for the designer, which is accomplished by the introduction of macro abstraction, interface inheritance, delayed binding, and the complete decoupling of procedural and graphical design information. These abstraction mechanisms are implemented in the Regular Structure Generator, an operational layout generator with significant advantages over first generation layout tools. Its advantages are demonstrated by a pipelined array multiplier layout example.
Engineering a Collagen Matrix that Replicates the Biological Properties of Native Extracellular Matrix (2011)

In this study, we aimed to replicate the function of native tissues that can be used in tissue engineering and regenerative medicine. The key to such replication is the preparation of an artificial collagen matrix that possesses a structure resembling that of the extracellular matrix. We, therefore, prepared a collagen matrix by fibrillogenesis in a NaCl/Na(2)HPO(4) aqueous solution using a dialysis cassette and investigated its biological behavior in vitro and in vivo. The in vitro cell adhesion and proliferation did not show any significant differences. The degradation rate in the living body could be controlled according to the preparation condition, where the collagen matrix with high water content (F-collagen matrix, >98%) showed fast degradation and collagen matrix with lower water content (T-collagen matrix, >80%) showed no degradation for 8 weeks. The degradation did not affect the inflammatory response at all and relatively faster wound healing response was observed. Comparing this result with that of collagen gel and decellularized cornea, it can be concluded that the structural factor is very important and no cell abnormal behavior would be observed for quaternary structured collagen matrix.
