Two Novel Resveratrol Derivatives from the Leaves of Vateria indica (2009)

Abstract magnified image Two new resveratrol (=5‐[( E )‐2‐(4‐hydroxyphenyl)ethenyl]benzene‐1,3‐diol) derivatives, vateriaphenols D ( 1 ) and E ( 2 ), were isolated from the leaves of Vateria indica (Dipterocarpaceae), together with six known resveratrol oligomers ( 3 – 8 ), a isocoumarin (bergenin, 9 ), and a benzophenone ( 10 ). The structures of the isolates were established on the basis of spectroscopic analyses, including a detailed NMR spectroscopic investigation. Compound 1 is composed of three resveratrol units and a piceatannol (=5‐[( E )‐2‐(3,4‐dihydroxyphenyl)ethenyl]benzene‐1,3‐diol) unit, and is the first instance of a heterogeneous coupled stilbene tetramer in dipterocarpaceaeous plants. Compound 2 bears a rare 2,3‐dihydrobenzofuran‐2‐ol skeleton in the framework.
ISI Compensation up to Nyquist Channel Spacing for Strongly Filtered PDM RZ-QPSK using Multi-Tap CMA (2012)

We experimentally demonstrate inter-symbol interference (ISI) mitigation using a multi-tap constant modulus algorithm (CMA) for strongly filtered PDM RZ-QPSK and find it to be effective up to Nyquist channel spacing after transpacific transmission distances.
Construction of a Compact Modeling Platform and Its Application to the Development of Multi-Gate MOSFET Models for Circuit Simulation (2008)

We aim at constructing a common platform for compact model development based on the Verilog-A language for collaboration among different research groups. The project aims in particular at a framework for efficient development of multi-gate MOSFET models for circuit simulation. We have developed several prototypes of multi-gate MOSFET models based on different concepts till now. Phenomena expected to become important for the multi-gate MOSFET generation are modeled on the basis of their physical origins. These phenomena are implemented into each of the specific multi-gate MOSFET models by plugging in modules from the common platform. Parasitic resistive and capacitive contributions are also modularized to represent the complete circuit performance of the multi-gate MOSFET device for efficient circuit development.

Novel approach to computer modeling of seven-helical transmembrane proteins: current progress in the test case of bacteriorhodopsin. (2001)

G-protein coupled receptors (GPCRs) are thought to be proteins with 7-membered transmembrane helical bundles (7TM proteins). Recently, the X-ray structures have been solved for two such proteins, namely for bacteriorhodopsin (BR) and rhodopsin (Rh), the latter being a GPCR. Despite similarities, the structures are different enough to suggest that 3D models for different GPCRs cannot be obtained directly employing 3D structures of BR or Rh as a unique template. The approach to computer modeling of 7TM proteins developed in this work was capable of reproducing the experimental X-ray structure of BR with great accuracy. A combination of helical packing and low-energy conformers for loops most close to the X-ray structure possesses the r.m.s.d. value of 3.13 A. Such a level of accuracy for the 3D-structure prediction for a 216-residue protein has not been achieved, so far, by any available ab initio procedure of protein folding. The approach may produce also other energetically consistent combinations of helical bundles and loop conformers, creating a variety of possible templates for 3D structures of 7TM proteins, including GPCRs. These templates may provide experimentalists with various plausible options for 3D structure of a given GPCR; in our view, only experiments will determine the final choice of the most reasonable 3D template.

Synthesis and Structure−activity Relationships of Antitubercular 2-Nitroimidazooxazines Bearing Heterocyclic Side Chains (2009)

Recently described biphenyl analogues of the antituberculosis drug PA-824 displayed improved potencies against M. tuberculosis but were poorly soluble. Heterobiaryl analogues of these, in which the first phenyl ring was replaced with various 5-membered ring heterocycles, were prepared with the aim of identifying potent new candidates with improved aqueous solubility. The compounds were constructed by coupling the chiral 2-nitroimidazooxazine alcohol with various halomethyl-substituted arylheterocycles, by cycloadditions to a propargyl ether derivative of this alcohol, or by Suzuki couplings on haloheterocyclic methyl ether derivatives. The arylheterocyclic compounds were all more hydrophilic than their corresponding biphenyl analogues, and several showed solubility improvements. 1-Methylpyrazole, 1,3-linked-pyrazole, 2,4-linked-triazole, and tetrazole analogues had 3- to 7-fold higher MIC potencies against replicating M. tb than predicted by their lipophilicities. Two pyrazole analogues were >10-fold more efficacious than the parent drug in a mouse model of acute M. tb infection, and one displayed a 2-fold higher solubility.

Binary-level data dependence analysis of hot execution regions using abstract interpretation at runtime (2020)

With the widespread of multicore systems, automatic parallelization becomes more pronounced, particularly for legacy programs, where the source code is not generally available. An essential operation in any parallelization system is detecting data dependence among parallelization candidate instructions. Conducting dependence analysis at the binary-level is more challenging than that at the source-level due to the much lower semantics of the binary code. In this paper, we consider using the elaborate 'static' analysis of abstract interpretation, for the first time, at runtime for data dependence detection. Specifically, our system interprets instructions at a hot region, while at the same time, collect programs semantics for seen program points, thereby conducting abstract interpretation analysis dynamically. The analysis is guaranteed to be correct as long as execution does not exit the region prematurely. Moreover, successive hot region re-entries will resume previous analysis, albeit much faster in case no major change in the program semantics. Such approach provides for more rigorous analysis than other simple dynamic analysis which would typically miss parallelization opportunities. The proposed approach also does not require any hardware support, availability of the source code, as well as any code re-compilation. To study the performance and accuracy of our approach, we have extended the Padrone dynamic code modification framework, and conduct an initial study on a set of PolyBench kernels and selected programs from SPEC CPU. Experimental results show accurate dependence detection with low overhead.
Distributed Image Coding for Digital Image Recovery From the Print-Scan Channel (2009)

A printed digital photograph is difficult to reuse because the digital information that generated the print may no longer be available. This paper describes a method for approximating the original digital image by combining a scan of the printed photograph with digital auxiliary information kept together with the print. We formulate and solve the approximation problem using a Wyner-Ziv coding framework. During encoding, the Wyner-Ziv auxiliary information consists of a small amount of digital data composed of a number of sampled luminance pixel blocks and a number of sampled color pixel values to enable subsequent accurate registration and color-reproduction during decoding. The registration and color information is augmented by an additional amount of digital data encoded using Wyner-Ziv coding techniques that recovers residual errors and lost high spatial frequencies. The decoding process consists of scanning the printed photograph, together with a two step decoding process. The first decoding step, using the registration and color auxiliary information, generates a side-information image which registers and color corrects the scanned image. The second decoding step uses the additional Wyner-Ziv layer together with the side-information image to provide a closer approximation of the original, reducing residual errors and restoring the lost high spatial frequencies. The experimental results confirm the reduced digital storage needs when the scanned print assists in the digital reconstruction.

Error free transmission of 64 WDM 10 Gb/s channels over 520 km of Truewave/sup TM/ fiber (2002)

We report error-free transmission of 64/spl times/10 Gb/s channels with 50 GHz spacing using high power, flat gain (35 nm bandwidth) erbium-doped silica fiber amplifiers. The amplifier spacing was 80-40 km, and the total end-of-system gain nonuniformity among the 64 channels was 6.4 dB.
A Coarse-Fine VCO-ADC for MEMS Microphones With Sampling Synchronization by Data Scrambling (2020)

This letter presents a mostly digital analog-to-digital converter implemented with voltage-controlled oscillators that can directly interface a capacitive MEMS microphone. The ADC is based on two ring oscillators and a coarse-line counting circuitry. Coarse and line counters are synchronized using a novel data scrambling technique to mitigate metastability and timing errors. This method enables a very low power consumption in the digital post-processing circuit. The proposed ADC, prototyped in 130-nm CMOS, achieves 73.8 dB-A of signal-to-noise and distortion ratio (SNDR) peak and 97 dB of dynamic range (DR) in a 20-kHz BW, while consuming 240 μW from the 1.5-V/1.2-V power supplies. In a reduced power mode (8 kHz BW) with relaxed oscillation parameters, it reaches 66.4 dB-A of SNDR peak and 93 dB of DR with a power consumption of only 77 μW.
Autonomic execution of Web service compositions (2005)

An increasing amount of Web services are being implemented using process management tools and languages (BPML, BPEL, etc.). The main advantage of processes is that designers can express complex business conversations at a high level of abstraction, even reusing standardized business protocols. The downside is that the infrastructure behind the Web service becomes more complex. This is particularly critical for Web services that may be subjected to high variability in demand and suffer from unpredictable peaks of heavy load. In this paper we present a flexible architecture for process execution that has been designed to support autonomic scalability. The system runs on a cluster of computers and reacts to workload variations by altering its configuration in order to optimally use the available resources. Such changes happen automatically and without any human intervention. This feature completely removes the need for the manual monitoring and reconfiguration of the system, which in practice is a difficult and time-consuming operation. In the paper we describe the architecture of the system and present an extensive performance evaluation of its autonomic capabilities.
Notch reduction in silicon on insulator (SOI) structures using a time division multiplex etch processes (2005)

Time division multiplexed (TDM) plasma etch processes have found widespread applications in Micro-Electro-Mechanical Systems (MEMS) device manufacturing. Very often, silicon-on-insulator (SOI) structures are used in MEMS applications with oxide layers used as etch stop/sacrificial layers as well as device function layers. Apart from the conventional requirements for deep silicon etch including high rate, selectivity and sidewall smoothness. SOI structures require finished etches to be free of undercut, commonly referred to as notching, at the silicon/oxide interface. Notching is aggravated due to the aspect ratio dependence (ARDE) effects. The ARDE effects cause structures with different aspect ratio to be etched at different etch rates, and result in the buried oxide layer in bigger features to be exposed while smaller features are still being etched. At Unaxis USA, we have developed a proprietary technique to eliminate the notch formation while maintaining high etch rate. This technique is integrated into time division multiplexed (TDM) Si etch processes, and is implemented in a single etch process. The conventional "bulk" etch to "finish" etch transition is thus made unnecessary, with the benefit of no end point detection and smooth and uniform etch profile. Etch processes are characterized and notch performance is measured as a function over etch percentage and feature aspect ratio. Using the new SOI etching technique, notching is completely eliminated in aspect ratios up to 9:1 and reduced to well below 100 nm for aspect ratios up to 18:1. Moreover, this new technique has been demonstrated to limit the effect of extensive overetch in increasing notch size.
Peer-Reviewed Technical Communication MIMO-OFDM for High-Rate Underwater Acoustic Communications (2009)

Abstract—Multiple-input–multiple-output (MIMO) techniques have been actively pursued recently in underwater acoustic com-munications to increase the data rate over the bandwidth-limited channels. In this communication, we present a MIMO system design, where spatial multiplexing is applied with orthogonal-fre-quency-division-multiplexing (OFDM) signals. The proposed receiver works on a block-by-block basis, where null subcarriers are used for Doppler compensation, pilot subcarriers are used for channel estimation, and a MIMO detector consisting of a hybrid use of successive interference cancellation and soft minimum mean square error (MMSE) equalization is coupled with low-density parity-check (LDPC) channel decoding for iterative detection on each subcarrier. The proposed design has been tested using data recorded from three different experiments. A spectral efficiency of 3.5 b/s/Hz was approached in one experiment, while a data rate of
Electric impedance platelet aggregometry in cardiac surgery patients: A comparative study of two technologies (2015)

Platelet function tests are suggested to assess platelet reactivity before cardiac and major non-cardiac surgery. Different point-of-care platelet function tests are available. Among these, electric impedance platelet aggregometry (EIPA) (Multiplate®, MP) is one of the most widely used techniques. Recently, a new EIPA system (Rotem Platelet®, RP) was released. This is a comparative study of platelet function measured with MP and RP. Fifty cardiac surgery patients were admitted to this study. All the patients received a preoperative platelet function test with both the MP and the RP; for each technology, two tests were performed: the ADPtest (investigating P2Y12 receptor platelet reactivity) and the TRAPtest (investigating the thrombin-dependent platelet reactivity). ADP-based platelet reactivity values demonstrated a significant (p = 0.019) correlation between the MP and the RP; and a marginally significant (p = 0.042) correlation for TRAP-based tests. The Bland-Altman analysis of the ADPtest demonstrated a positive bias of 5.94 units (MP > RP) and a percentage error of 88%. For the TRAPtest, there was a positive bias of 12 units (MP > RP) and a percentage error of 89%. In patients who were preoperatively treated with P2Y12 receptor inhibitors, only the MP ADPtest was positively associated with the days from drug discontinuation (p = 0.003). Platelet function assessment with RP greatly differs from the equivalent MP measure, and no correction value can be applied due to the low level of precision. This applies both to ADPtest and TRAPtest. The MP ADPtest is more reliable for platelet reactivity after discontinuation of P2Y12 receptor inhibitors.
Lead-Free Halide Double Perovskites via Heterovalent Substitution of Noble Metals (2016)

Lead-based halide perovskites are emerging as the most promising class of materials for next generation optoelectronics. However, despite the enormous success of lead-halide perovskite solar cells, the issues of stability and toxicity are yet to be resolved. Here we report on the computational design and the experimental synthesis of a new family of Pb-free inorganic halide double-perovskites based on bismuth or antimony and noble metals. Using first-principles calculations we show that this hitherto unknown family of perovskites exhibits very promising optoelectronic properties, such as tunable band gaps in the visible range and low carrier effective masses. Furthermore, we successfully synthesize the double perovskite Cs2BiAgCl6, we perform structural refinement using single-crystal X-ray diffraction, and we characterize its optical properties via optical absorption and photoluminescence measurements. This new perovskite belongs to the Fm-3m space group, and consists of BiCl6 and AgCl6 octahedra alternating in a rock-salt face-centered cubic structure. From UV-Vis and PL measurements we obtain an indirect gap of 2.2 eV. The new compound is very stable under ambient conditions.
Rotational alignment of NO from Pt(111). Inelastic scattering and molecular desorption (1989)

The rotational alignment distribution of NO has been measured subsequent to the molecule's interaction with a well characterized Pt(111) surface. Internal state distributions have been probed using 1 + 1 resonance-enhanced multiphoton ionization (REMPI) spectroscopy in which lines of the NO A 2Σ+–X2Π(0, 0) band constitute the resonant transition. NO/Pt(111) scattering has been studied in two distinct regimes: inelastic scattering and trapping/desorption. In both cases, there is relatively no preferential alignment of rotation for J < 12.5. However, molecules with higher rotational angular momentum show a marked increase in alignment. Inelastically scattered molecules prefer to rotate in a plane normal to the surface (‘cartwheel’ motion), whereas desorbing molecules prefer to rotate in a plane parallel to the surface (‘helicopter’ motion). These measurements provide new insight into momentum transfer at surfaces and the nature of the transition state which leads to molecular desorption.
Erstes Kapitel: § 54a KWG im System des Finanzaufsichtsrechts (2023)

Die Arbeit beschäftigt sich mit der Schnittstelle zwischen Straf- und Aufsichtsrecht. Am Beispiel des § 54a KWG wird empirisch untersucht, wie sich das Strafrecht in Bereiche der prinzipienorientierten (Finanz-)Aufsicht einfügt. Um am kognitiven Potential der Institute zu partizipieren, normiert der Gesetzgeber mit § 25c Abs. 4a KWG prozedurale Anforderungen an das Risikomanagement und überlässt die konkrete Art der Umsetzung dieser Vorgaben den Instituten. Zugleich hat der Gesetzgeber mit § 54a KWG einen Verstoß gegen diese Risikomanagementvorgaben strafbewehrt. Dies führt zwangsläufig zu Spannungsverhältnissen – insbesondere mit den Zielen des Aufsichtsrechts und der vom Gesetzgeber normierten institutsinternen Wissensgenerierung.
Optimization Methodology of PMSM Cooled by External Convection in Aircraft Propulsion (2020)

Nowadays, the reduction of aircraft emissions is one of the industrial targets with a horizon time until 2050. The recent progresses in electrical drives give the opportunity to modify the aircraft propulsion based on thermal engine or gas turbine to a hybrid/full electric one. Some problems must be solved: weight, reliability, and the choice of the best configuration for the electric propulsion. One of the most important aspects to solve is the thermal behavior of power converters and electric motors. This paper proposes an optimization procedure for the design of surface permanent magnet motors used for the aircraft propulsion: the aim of the paper is to investigate the possibility of cooling the motor with only the air flow due to the aircraft speed. The optimization procedure has been solved with the integration of analytical model and finite element analysis and using a differential evolution algorithm.
