Business Angels und Hightech-Gründungen (2007)

"Business Angels" spielen in der Frühphase für die Finanzierung von jungen Hightech- Unternehmen eine wichtige Rolle. Sie übernehmen dabei die noch vor wenigen Jahren von Risikokapitalunternehmen ausgefüllte Rolle des wichtigsten Gebers von externem Eigenkapital für neue Hochtechnologieunternehmen. Dies gilt nicht nur in den Vereinigten Staaten, Schweden oder im Vereinigten Königreich. Auch in Deutschland sind Business Angels in der Startphase inzwischen wichtiger als Risikokapitalgesellschaften. Dies ergab eine im Auftrag des Bundesministeriums für Wirtschaft und Technologie (BMWi) durchgeführte Studie des ZEW, bei der im Frühjahr 2007 rund 3.000 Unternehmen aus FuE-und technologieintensiven Wirtschaftszweigen befragt wurden.
Research of Weak AC Current Accuracy Measurement Based on ADE7816 (2013)

Converted current signal by mutual inductance coil is merely microampere level when using current transformers measure milliamps-power currents, the weak signal is too easily be interference by external environment to achieve accurate measurements. For the power current below 6mA, designed a system based on energy metering chip ADE7816. By analyzing the experimental results, proposed schemes to reduce the measurement error for the first time. The results show that, when the load is maintained at 10Ω and the value of PGA is set to 4 from 0, the average relative error of results is reduced to 0.63%; additionally, when the value of PGA is maintained at 0, but the load Increased to 52Ω from10Ω, the average relative error of results is 0.02%.
Fluorene‐based conjugated polymer with tethered thymines: click postpolymerization synthesis and optical response to mercury(II) (2012)

Abstract A kind of fluorene‐based conjugated polymer with tethered thymine (T) groups {poly[(9,9‐dioctyl)‐2,7‐fluorene‐{9,9‐dioctyl‐4–1,2,3‐triazol‐[5‐(hydroxymethyl)tetrahydrofuran‐2‐yl]‐5‐methylpyrimidine‐2,4(1H,3H)‐dione}‐2,7‐fluorene]‐ co ‐[(9,9‐dioctyl)‐2,7‐fluorene‐4,7‐bis(5‐thiophen‐2‐yl)benzo‐2,1,3‐thiadiazole] ( P‐3 )} was successfully synthesized by a Cu(I)‐catalyzed click reaction between the acetylene‐substituted polymer precursor {poly[(9,9‐dioctyl)‐2,7‐fluorene‐(9,9‐dioctyl‐4‐phenylacetylene fluorene)]‐ co ‐[(9,9‐dioctyl)‐2,7‐fluorene‐4,7‐bis(5‐thiophen‐2‐yl)benzo‐2,1,3‐thiadiazole]} and 3′‐azido‐3′‐deoxythymidine. The chemical structures of the intermediates and target polymer were verified by Fourier transform infrared spectroscopy and 1 H‐NMR analyses. The specific binding with Hg 2+ of P‐3 was corroborated by ultraviolet–visible spectroscopy and photoluminescence analyses against other metal ions. The results show that P‐3 possessed selectivity and sensitivity toward Hg 2+ . Around 77% of photoluminescence intensity of P‐3 was quenched when the concentration of Hg 2+ reached 7.7 × 10 −4 M and with a detection limit in the range of about 4.8 μ M . A comparison experiment suggested that a synergic effect of the tethered T and S atoms interrelated with Hg 2+ existed in P‐3 . Most of the fluorescence intensity of P‐3 was recovered upon the addition of iodide anions to the P‐3 /Hg 2+ complex; this suggested that P‐3 could be used as a potential reversible optical Hg 2+ probe. © 2013 Wiley Periodicals, Inc.

Twin-stack decoding of recursive systematic convolutional codes (2001)

We present a method for soft-in/soft-out sequential decoding of recursive systematic convolutional codes. The proposed decoder, the twin-stack decoder, is an extension of the well-known ZJ stack decoder, and it uses two stacks. The use of the two stacks lends itself to the generation of soft outputs, and the decoder is easily incorporated into the iterative "turbo" configuration. Under thresholded decoding, it is observed that the decoder is capable of achieving near-maximum a posteriori bit-error rate performance at moderate to high signal-to-noise ratios (SNRs). Also, in the iterative (turbo) configuration, at moderate SNRs (above 2.0 dB), the performance of the proposed decoder is within 1.5 dB of the BCJR algorithm for a 16-state, R=1/3, recursive code, but this difference narrows progressively at higher SNRs. The complexity of the decoder asymptotically decreases (with SNR) as 1/(number of states), providing a good tradeoff between computational burden and performance. The proposed decoder is also within 1.0 dB of other well-known suboptimal soft-out decoding techniques.
<title>Near-Term Case For 5x Versus 10x Wafer Steppers</title> (1982)

A simplified but general model of wafer throughput for wafer steppers has been developed. The model shows clearly the throughput dependence on full-wafer overhead time, area of exposure field, alignment times, exposure time, and stage stepping time; trends are quite clear as to which parameters carry the most leverage, and which should therefore receive the resources for development. The model is used to compare the relative merits of two Zeiss lens series, a 5X wide-field lens and the standard 10X lens with regard to the anticipated IC production demands over the next five years. A case is made for the 5X lens, which can then later be replaced by the 10X lens.

Large Molecular Third-Order Optical Nonlinearities in Polarized Carotenoids (1997)

Garito and co-workers have suggested a mechanism to dramatically increase the second hyperpolarizability, gamma, in linear pi-electron-conjugated molecules. Polarization is introduced that leads to a difference between the dipole moments of the molecule's ground state and excited state. Here a series of carotenoids was examined that had increasing intramolecular charge transfer (ICT) from the polyenic chain to the acceptor moiety in the ground state, and gamma was measured for these compounds as a function of wavelength by third-harmonic generation. The compound with the greatest ICT exhibited a 35-fold enhancement of gammamax (the gamma measured at the peak of the three-photon resonance) relative to the symmetric molecule beta-carotene, which itself has one of the largest third-order nonlinearities known. Stark spectroscopic measurements revealed the existence of a large difference dipole moment, Delta mu, between the ground and excited state. Quantum-chemical calculations underline the importance of interactions involving states with large Delta mu.
Genomic Comparisons and Shiga Toxin Production among <i>Escherichia coli</i> O157:H7 Isolates from a Day Care Center Outbreak and Sporadic Cases in Southeastern Wisconsin (1998)

Contour-clamped homogeneous electric field pulsed-field gel electrophoresis (CHEF-PFGE) was used to compare Wisconsin isolates of Escherichia coli O157:H7, including 39 isolates from a 1994 day care center outbreak, 28 isolates from 18 individuals from the surrounding geographic area with sporadic cases occurring during the 3 months before the outbreak, and 3 isolates, collected in 1995, from patients with hemolytic-uremic syndrome (HUS) who were from eastern Wisconsin counties other than those inhabited by the day care center and sporadic-case individuals. The technique of CHEF-PFGE using XbaI identified seven highly related restriction endonuclease digestion profiles (REDPs) (93 to 98% similarity) among the 39 day care center isolates and nine XbaI REDPs (63 to 93% similarity) among the 28 isolates from sporadic-case individuals, including REDP 33, which was exhibited by both day care and sporadic-case isolates. PFGE analyses of sequential E. coli O157:H7 isolates from symptomatic day care center attendees revealed that the REDPs of 25 isolates from eight patients were indistinguishable whereas the REDPs of 2 of 6 isolates from two patients differed slightly (93 to 95% similarity). The REDPs of the three isolates from 1995 HUS patients were 78 to 83% similar, with REDP 26 being exhibited by one HUS-associated isolate and an isolate from one day care attendee who did not develop HUS. The genes for both Shiga toxins I and II (stx1 and stx2, respectively) were detected in all but one isolate (sporadic case), and Shiga toxin production by the day care center isolates was not significantly different from that of the other isolates, including the three HUS-associated isolates. Analyses of E. coli O157:H7 isolates from both the day care center outbreak and sporadic cases by CHEF-PFGE permitted us to define the REDP variability of an outbreak and geographic region and demonstrated that the day care center outbreak and a HUS case in 1995 were caused by E. coli O157:H7 strains endemic to eastern Wisconsin.
Dive in! (2014)

We introduce Splash, a framework reducing development overhead for both data curators and visualization developers of client-server visualization systems. Splash streamlines the process of creating a multiple level-of-detail version of the data and facilitates progressive data download, thereby enabling real-time, on-demand navigation with existing visualization toolkits. As a result, system responsiveness is increased and the user experience is improved. We demonstrate the benefit of progressive loading for user interaction on slower networks. Additionally, case study evaluations of Splash with real-world data curators suggest that Splash supports iterative refinement of visualizations and promotes the use of exploratory data analysis.
Single inductor, multiple input, multiple output (SIMIMO) power mixer-charger-supply system (2007)

A hybrid energy source has become a necessary solution for micro-scale applications, like wireless sensors, because of small form factor and extended lifetime requirements. Conventional power mixer circuits use two or more inductors, which become prohibitively area intensive in micro-scale applications where area for discrete inductors is scarce and on-chip inductors are poor. Although single inductor multiple input or multiple output converters appear in recent literature, they cannot be applied to the hybrid energy source directly. A single inductor, multiple input, multiple output (SIMIMO) power mixer-charger-supply system is therefore proposed for a hybrid fuel cell-lithium ion source. The SIMIMO system adopts a novel nested hysteretic mode dual-loop control architecture, regulating both the fuel cell current and the output voltage within predetermined hysteres is windows. A SIMIMO with 67% average efficiency was designed and simulated, regulating the fuel cell current to 10mA and output voltage to 1.8V within ±20mV.
EMG Biofeedback Based VR System for Hand Rotation and Grasping Rehabilitation (2010)

Individuals who have upper limb movement problems include people with cerebral palsy (CP) and stroke victims. Both these conditions lead to difficulties in daily activities such as reaching, grasping etc. Virtual reality (VR), which could provide a repetitive multimodal task-oriented rehabilitation environment for patients to undertake self-training in safety, is considered to be a suitable tool for medical health rehabilitation. Using electromyography (EMG) biofeedback in rehabilitation could provide patients with opportunities to improve the ability by assessing their muscle activity response and learning self-control of movement during specific training tasks. This paper presents a study on developing EMG as an important interactive tool in a VR based system for hand rotation and grasping motion rehabilitation. The input interface includes an EMG system and a real-time magnetic motion tracking system, and the output interface is a PC monitor. The developed EMG biofeedback based VR system enables the user to interact with virtual objects in real-time with multiform feedback. Ten healthy subjects participated in the preliminary task evaluation test, and the results suggest that the specified skills have improved during training. The beneficial effects of the developed system indicate the potential values for further clinical application.
A Prospective Study of the Effect of Hypertension and Baseline Blood Pressure on Cognitive Decline and Dementia in Postmenopausal Women: The Women's Health Initiative Memory Study (2008)

Hypertension and high blood pressure at baseline were not independently associated with MCI or probable dementia over time in older, cognitively intact, postmenopausal women enrolled in WHIMS after other potential confounders were taken into account. These analyses should not be viewed as discouraging appropriate medical treatment for hypertension.

A Dispersion Model for Coupled Microstrips (1986)

The frequency-dependent propagation characteristics of symmetrical, nonsymmetrical, and multiple coupled microstrips are evaluated by utilizing a directly coupled parallel-plate ideal waveguide model. The closed-form expressions for the frequency-dependent parameters of this proposed semi-empirical utility model are derived in terms of the quasi-static parameters of the coupled microstrip structure. These model parameters are then used to evaluate the frequency-dependent propagation characteristics, including the normal-mode effective dielectric constants and impedances of the coupled microstrips. These results are found to be in good agreement with all the published experimental results and the numerically computed values for symmetrical and nonsymmetrical coupled microstrips. The model should be useful in the computer-aided design of coupled microstrip structures at higher frequencies where the dispersion effects become important.

Isolation of Urinary Exosomes from Animal Models to Unravel Noninvasive Disease Biomarkers (2012)

In the last years, disease biomarker discovery has highly evolved thanks to the application of high--throughput technologies such as proteomics. However, due to the elevated complexity and abundance of some of the proteins in the samples the analysis of subcellular compartments has been revealed to be fundamental in order to identify underrepresented clinically relevant proteins. In this sense, extracellular microvesicles including exosomes that are present in different body fluids constitute a suitable and convenient subcellular compartment to identify disease biomarkers. On the other hand, animal models offer numerous advantages over human samples in order to accelerate the identification of candidate biomarkers. In this chapter we provide a detailed methodology to purify and analyze urinary exosomes that can be applied to the study of different diseases that have good animal models.
Mapping home-network appliances to TCP/IP sockets using a three-tiered home gateway architecture (1998)

A three-tier gateway architecture for internetworking between home automation networks and a TCP/IP based wide area network, such as the Internet, is described. The architecture abstracts the functionality of any home network into a driver layer (tier one), and provides a common access layer (tier two) from any TCP/IP network application (tier three) to a local home automation network. Clients and application programs may transparently access services and resources on the home network and appliances connected to the home network may access resources and services on the TCP/IP network.
Impedance Noise Identification for State-of-Health Prognostics (2008)

Impedance Noise Identification is an in-situ method of measuring battery impedance as a function of frequency using a random small signal noise excitation source. Through a series of auto- and cross-correlations and Fast Fourier Transforms, the battery complex impedance as a function of frequency can be determined. The results are similar to those measured under a lab-scale electrochemical impedance spectroscopy measurement. The lab-scale measurements have been shown to correlate well with resistance and power data that are typically used to ascertain the remaining life of a battery. To this end, the Impedance Noise Identification system is designed to acquire the same type of data as an on-board tool. A prototype system is now under development, and results are being compared to standardized measurement techniques such as electrochemical impedance spectroscopy. A brief description of the Impedance Noise Identification hardware system and representative test results are presented.
Development of a K-edge micro CT for the study of tumor angiogenesis in small animals (2006)

A new micro scanner CT for small animals - based on a couple of parallel quasi-monochromatic X-ray beams with different energies selectable - is under development at Physics Department of the University of Bologna. \n\nThe aim of the study is the in vivo imaging of the tumor neo-angiogenesis pattern in an earlier diagnostic phase and the analysis of cancer growth and metastasis development in different tumor types on mice. \n\nThe early diagnosis of cancer mainly relies on detection of precancerous changes, such as neo-angiogenesis. It represents one of the mechanisms of cancer development due to production of molecules in a very initial stage, stimulating new blood vessels creation, thus nourishing the cancer cells, which can continue to grow. \n\nAs previously demonstrated(1), the imaging system based on dual energy quasi-monochromatic X-ray beams provides higher sensitivity in detecting low concentrations of iodine contrast medium if compared to traditional polychromatic Xray equipment. The K-edge dual energy radiology is a realistic candidate to recognize tumor neo-angiogenesis process in a very earlier stage, in which conventional systems are very poor in sensitivity. \n\nMoreover, the capability to select the energy of quasi-monochromatic beams enables the use of the Multi-Energy Quasi-Monochromatic technique. Tuning properly the energies allows maximizing the difference between linear absorption coefficients of healthy and pathological tissues increasing the contrast of pathologies. In order to optimize the contrast with this technique, one should know the X-ray energy regions where the absorption of healthy and pathological tissues eventually differs and that for each type of tumor under study. For this reason, the systematic X-ray characterization of many types of healthy and neoplastic human and mice tissues is in progress. The goal of this work is to obtain a catalog of liner attenuation coefficients of a variety of pathological tissues for respect to the healthy ones, finding any energy windows of radiological differentiation. \n\nIn this paper, the theoretical methods are presented with development works and preliminary results.
On TCP performance in a heterogeneous network: a survey (2000)

Transmission media carrying Internet traffic present a wide range of characteristics, some of which, such as transmission errors, long end-to-end delay, and bandwidth asymmetry, may cause a degradation of the TCP performance. Many works have studied the performance of TCP over these media, most of which focus on a particular network type. In this work we study TCP performance independent of the type of network by considering the different possible characteristics of the connection path. We present the problems and the different proposed solutions. This study permits us to understand the limitations of the actual solutions and the required modifications to let TCP cope with a heterogeneous Internet on an end-to-end basis.
Increased replication of T-cell-tropic HIV strains and CXC-chemokine receptor-4 induction in T cells treated with macrophage inflammatory protein (MIP)-1α, MIP-1β and RANTES β-chemokines (1998)

Beta-chemokines increase the adsorption and replication of at least some T-cell-tropic HIV-1 strains, and this is related to stimulated expression of the CXCR-4 coreceptor.
vGPRS: a mechanism for voice over GPRS (2002)

This paper proposes vGPRS, a voice over IP (VoIP) mechanism for a general packet radio service (GPRS) network. In this approach, a new network element called VoIP mobile switching center (VMSC) is introduced to replace standard GSM MSC. The vGPRS approach is implemented using standard H.323, GPRS, and GSM protocols. Thus, existing GPRS and H.323 network elements are not modified. Furthermore, both standard GSM and GPRS mobile stations can be used to receive vGPRS service, which need not be equipped with the VoIP (i.e., H.323) terminal capabilities.
A Study of Group-Type Single-Phase Unidirectional Saw Transducers on LiNb03 and Quartz. (1985)

This Memorandum describes a development of the SPUDT (Single Phase Undirectional Transducer) concept. The fabrication of such devices requires a single stage of photolithography. Prototype devices have shown very encouraging passband characteristics with an insertion loss of less than 3 dB on LiNb03 at 100 MHz, and less than 6 dB on quartz at 400 MHz. In each case the amplitude response is essentially ripple-free, and the phase characteristic agreeable linear. (Great Britain)
Fatigue analysis of clinical bioprosthetic heart valves manufactured using photooxidized bovine pericardium. (2000)

Previous studies have shown a good qualitative, quantitative association between fatigue failure in Rowan Ash accelerated fatigue testers, and clinical experience in glutaraldehyde-treated bovine pericardial valves. The accelerated fatigue tester did not provide an adequate model for the prediction of clinical failure for the photooxidized pericardial valves.
