Organometallchemie mit Molybdän‐ und Wolframalkoxidclustern; Vergleich mit Carbonylclustern der späten Übergangsmetalle (1989)

Abstract Alkoxid‐ und Carbonylliganden ergänzen sich in ihren π‐Wechselwirkungen mit Übergansgsmetallen, weil Alkoxidliganden als π‐Donoren durch Elektronenübertragung in leere d π ‐Orbitale frühe Übergangsmetalle in hohen Oxidationsstufen und Carbonylliganden als π‐Acceptoren durch Elektronenaufnahme aus besetzten d π ‐Orbitalen späte Übergangsmetalle in niedrigen Oxidationsstufen stabilisieren. Beide Liganden fungieren ohne weiteres als Brückenliganden über M‐M‐Bindungen. In Lösung sind Fluktuationen zwischen terminalen und Brückenpositionen sowohl für Alkoxid‐ als auch für Carbonylliganden üblich. Die Fragmente [W(OR) 3 ], [CpW(CO) 2 ], [Co(CO) 3 ] und CH sind isolobal, also sind auch die Verbindungen [(RO) 3 W  W(OR) 3 ], [Cp(CO) 2 W  W(CO) 2 CP], das hypothetische [(CO) 3 Co  Co(Co) 3 ] und HC  CH isolobal. Alkoxid‐ und Carbonylcluster zeigen oft verblüffende Ähnlichkeiten bei der Bindung von Substraten, z.B. [W 3 (μ 3 ‐CR)(OR′) 9 ] und [Co 3 (μ 3 ‐CR)(CO) 9 ] sowie [W 4 (C)(NMe)(O i Pr) 12 ] und [Fe 4 (C)(CO) 13 ], unterscheiden sich aber bezüglich der M‐M‐Bindungen. Bei Carbonylclustern werden e g ‐Orbitale, bei Alkoxidclustern t 2g ‐Orbitale für die M‐M‐Bindungen benutzt. Ein weiterer Unterschied ist die elektronische Absättigung. In einem Carbonylcluster hat im allgemeinen jedes Metallatom 18 Valenzelektronen, so daß zur Aktivierung des Clusters eine thermische oder photochemische CO‐Abspaltung oder die Spaltung einer M‐M‐Bindung nötig sind. Alkoxidcluster sind dagegen elektronisch nicht abgesättigt, weil die π‐Elektronen an den Liganden und das LUMO am Metall zentriert sind. Bei Alkoxidclustern kann darüber hinaus der Zugang zu den Metallzentren sterisch durch die Wahl der Alkoxidgruppen gesteuert werden, während bei Carbonylclustern zur Modifizierung sterischer Faktoren Hilfsliganden wie tertiäre Phosphane oder Cyclopentadienylliganden eingeführt werden müssen. In diesem Aufsatz werden die Reaktivitäten von Alkinen und von Ethylen gegenüber zweikernigen Alkoxid‐ und Carbonylkomplexen verglichen. Bei letzteren ist die Abspaltung von CO‐Liganden Voraussetzung für die Substrataufnahme und nachfolgende Aktivierung. Bei [M 2 (OR) 6 ]‐Verbindungen (M = Mo, W) ist die Art der Substrataufnahme und Aktivierung abhängig von M und R, was zu einer vielfältigeren Chemie führt.
Hyperactive auditory processing in Williams syndrome: Evidence from auditory evoked potentials (2015)

The neurophysiologic aberrations underlying the auditory hypersensitivity in Williams syndrome (WS) are not well defined. The P1-N1-P2 obligatory complex and mismatch negativity (MMN) response were investigated in 18 participants with WS, and the results were compared with those of 18 age- and gender-matched typically developing (TD) controls. Results revealed significantly higher amplitudes of both the P1-N1-P2 obligatory complex and the MMN response in the WS participants than in the TD controls. The P1-N1-P2 complex showed an age-dependent reduction in the TD but not in the WS participants. Moreover, high P1-N1-P2 complex was associated with low verbal comprehension scores in WS. This investigation demonstrates that central auditory processing is hyperactive in WS. The increase in auditory brain responses of both the obligatory complex and MMN response suggests aberrant processes of auditory encoding and discrimination in WS. Results also imply that auditory processing may be subjected to a delayed or diverse maturation and may affect the development of high cognitive functioning in WS.
Fundamental Performance Limits of Carbon Nanotube Thin-Film Transistors\n Achieved Using Hybrid Molecular Dielectrics (2012)

In the past decade, semiconducting carbon nanotube thin films have been\nrecognized as contending materials for wide-ranging applications in\nelectronics, energy, and sensing. In particular, improvements in large-area\nflexible electronics have been achieved through independent advances in\npost-growth processing to resolve metallic versus semiconducting carbon\nnanotube heterogeneity, in improved gate dielectrics, and in self-assembly\nprocesses. Moreover, controlled tuning of specific device components has\nafforded fundamental probes of the trade-offs between materials properties and\ndevice performance metrics. Nevertheless, carbon nanotube transistor\nperformance suitable for real-world applications awaits understanding-based\nprogress in the integration of independently pioneered device components. We\nachieve this here by integrating high-purity semiconducting carbon nanotube\nfilms with a custom-designed hybrid inorganic-organic gate dielectric. This\nsynergistic combination of materials circumvents conventional design\ntrade-offs, resulting in concurrent advances in several transistor performance\nmetrics such as transconductance (6.5 {\\mu}S/{\\mu}m), intrinsic field-effect\nmobility (147 cm^2/Vs), sub-threshold swing (150 mV/decade), and on/off ratio\n(5 x 10^5), while also achieving hysteresis-free operation in ambient\nconditions.\n

A concurrent architecture for serializable production systems (1996)

This paper presents a new production system architecture that takes advantage of modern associative memory devices to allow parallel production firing, concurrent matching, and overlap among matching, selection, and firing of productions. We prove that the results produced by the architecture are correct according to the serializability criterion. A comprehensive event driven simulator is used to evaluate the scaling properties of the new architecture and to compare it with a parallel architecture that does global synchronization before every production firing. We also present measures for the improvement in speed due to the use of associative memories and an estimate for the amount of associative memory needed. Architectural evaluation is facilitated by a new benchmark program that allows for changes in the number of productions, the size of the database, the variance between the sizes of local data clusters, and the ratio between local and global data. Our results indicate that substantial improvements in speed can be achieved with a very modest increase in hardware cost.
Perfect vs. Independent Feedback in the Multiple-Access Channel (2023)

The multiple access channel (MAC) capacity with feedback is considered under feedback models designed to tease out which factors contribute to the MAC feedback capacity benefit. Comparing the capacity of a MAC with ``perfect'' feedback, which causally delivers to the transmitters the true channel output, to that of a MAC with ``independent'' feedback, which causally delivers to the transmitters an independent instance of that same channel output, allows separation of effects like cooperation from alternative feedback benefits such as knowledge of the channel instance. Proving that the Cover-Leung (CL) achievability bound, which is known to be loose for some channels, is achievable also under (shared or distinct) independent feedback at the transmitters shows that the CL bound does not require transmitter knowledge of the channel instance. Proving that each transmitter's maximal rate under independent feedback exceeds that under perfect feedback highlights the potential power of an independent look at the channel output.

How the Patient Protection and Affordable Care Act (PPACA) Supports Federalism (2012)

Copyright: © 2012 Mehta J, et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Since its enactment on March 23, 2010, much of the commentary on the Patient Protection and Affordable Care Act (PPACA) has focused on whether the Act unduly eviscerates long-enshrined views of federalism1. While conventional wisdom is that PPACA is a watershed moment in the federal government’s usurpation of state powers, this criticism adopts an unduly narrow view of states’ rights and the notion of federalism. Rather than rebuking federalism, the PPACA actually augments federalist principles in important ways. Ultimately, by putting aside the federalism attacks, both proponents and opponents of the legislation can focus on and debate the merits of the legislation.
Distribution of aromatic L‐amino acid decarboxylase mRNA in mouse brain by in situ hybridization histology (1993)

Aromatic L-amino acid decarboxylase (AAAD) is the second enzyme in the sequence leading to the synthesis of catecholamines or serotonin. Antisense riboprobes for aromatic L-amino acid decarboxylase mRNA were used to map the gene in mouse brain by in situ hybridization. The substantia nigra, the ventral tegmental nucleus, the dorsal raphe nucleus, the locus coeruleus, and the olfactory bulb contained the highest signal for AAAD mRNA. After treatment with the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), the signal disappeared in the substantia nigra, decreased somewhat in the ventral tegmental area, and remained unchanged in the dorsal raphe nucleus. Hypothalamic and cerebellar Purkinje neurons known to contain histidine decarboxylase or glutamic acid decarboxylase, respectively, were unlabeled by the probes. However, neurons in the deep layers of the frontal cortex, many thalamic nuclei, and the pyramidal neurons of the hippocampus were lightly to moderately labeled for mouse AAAD mRNA. The presence of AAAD message in these neurons suggests that the enzyme has functions other than that for the synthesis of the classical biogenic amine neurotransmitters.
SAOC FOR GAMING - THE UPCOMING MPEG STANDARD ON PARAMETRIC OBJECT BASED AUDIO CODING (2009)

Following the current trend of employing parametric enhancement tools for increasing coding and spatial rendering efficiency, the MPEG audio group performs the standardization activities on Spatial Audio Object Coding (SAOC) technology. The SAOC system extends the MPEG Surround standard by exploiting its rendering capability and decoding efficiency. Moreover, the SAOC technology introduces user-controllable rendering functionality together with flexible choice of various playback configurations. These aspects are of potential interest for a large range of gaming applications that will benefit from the efficient coding and interactive rendering. Although SAOC targets many different application scenarios, this paper will describe the basic SAOC architecture and the manifold of enhancement tools, with a specific focus on the relevance for gaming applications.
Psychophysical reverse correlation reflects both sensory and decision-making processes (2018)

Abstract Goal directed behavior depends on both sensory mechanisms that gather information from the outside world and decision-making mechanisms that select appropriate behavior based on that sensory information. Psychophysical reverse correlation is commonly used to quantify how fluctuations of sensory stimuli influence behavior and is generally believed to uncover the spatiotemporal weighting functions of sensory processes. Here we show that reverse correlations also reflect decision-making processes and can deviate significantly from the true sensory filters. Specifically, changes of decision bound and mechanisms of evidence integration systematically alter psychophysical reverse correlations. Similarly, trial-to-trial variability of sensory and motor delays and decision times causes systematic distortions in psychophysical kernels that should not be attributed to sensory mechanisms. We show that ignoring details of the decision-making process results in misinterpretation of reverse correlations, but proper use of these details turns reverse correlation into a powerful method for studying both sensory and decision-making mechanisms.
Power efficient real-time disk scheduling (2009)

Hard-disk drive power consumption reduction methods focus mainly on increasing the amount of time the disk is in standby mode (disk spun down) by implementing aggressive data read-ahead and caching at the operating system and/or application level. However, these methods cannot be applied efficiently to systems with limited memory and high bit-rate requirements such as digital video recorders handling high-definition video. In this paper, we introduce the Audio/Video File System (AVFS), composed of a file system and a disk I/O scheduler. Compared to traditional methods, the proposed scheduler reduces seek overhead by processing real-time requests to video files using batches built dynamically depending on the requests deadlines. Evaluation results show an important reduction in disk utilization rates and a reduction of up to 20 % of the disk power consumption with only 4 MB of data buffer per video stream.
Distortion and impairments mitigation and compensation of single‐ and multi‐band wireless transmitters (invited) (2013)

Transmitter digital domain linearisation solutions are constantly evolving to extract optimum benefits in terms of cost, performance and flexibility. This study highlights the current and futuristic trends in the arena of transmitter system modelling and digital domain compensation for radio frequency distortions of non‐linear power amplifiers and wireless transmitters in case of single‐band wireless transmitter, which is further extended to a dual‐band transmitter. Indeed, the dual‐band transmitter results in severe non‐linear distortion as compared to the single‐band transmitter when operated in concurrent mode, due to the additional inter‐modulation products generated by the dual‐band transmitted signals. Hence, in addition to the intermodulation products and memory effects exhibited in a single‐band transmitter, the cross‐modulation effects of the dual‐band signals should be compensated for as well in a dual‐band transmitter. The effects of the modulator imperfections such as gain and phase imbalances, phase errors and DC offsets and their impact on the feedback loop of a digital predistortion system are also analysed. A thorough comparison between the state‐of‐the‐art behavioural models and their application to digital predistortion technique of power amplifier is presented in terms of performance and complexity. Model performance assessment is discussed through simulation and experimental results for both single‐ and dual‐band systems.
Nano-pillar structure for sensitivity enhancement of SPR sensor (2009)

We report on a method to increase sensitivity of SPR (Surface Plasmon Resonance) sensor using nano-pillar structures as a protein adhesion site. The dense and tall nano-pillar array increases a virtual protein adhesion area within an SPR electromagnetic field (EMF) so that an SPR dip shift increases compared with a conventional SPR sensor. Fabricated silica nano-pillar chip with 200-nm-pitch and 570-nm-height pillar array was assembled with an optical prism with an Au film, and sensitivity enhancement for protein measurement by the nano-pillar was examined. The SPR measurement result exhibited a significant dip shift increase, about ten folds of that of the normal SPR device. The nano-pillar SPR has a potential of increasing sensitivity of SPR in detecting proteins.

Compact Full Duplex MIMO Radios in D2D Underlaid Cellular Networks: From System Design to Prototype Results (2017)

This paper considers the implementation and application possibilities of a compact full duplex multiple-input multiple-output (MIMO) architecture, where direct communication exists between users, e.g., device-to-device (D2D) and cellular link coexisting on the same spectrum. For the architecture of the compact full duplex radio, we combine an analog self-interference canceler-based dual polarization with high cross-polarization discrimination and long-term evolution (LTE)-based per-subcarrier digital self-interference canceler. While we consider the compactness and power efficiency of an analog solution, we focus on the digital canceler design with robustness to a frequency-selective channel and high compatibility with a conventional LTE system. For an over-the-air wireless experiment of full duplex testbed with a two-user-pair, we implement a full duplex MIMO physical layer, supporting 20-MHz bandwidth, on an Field-Programmable Gate Array-based software-defined radio platform. Furthermore, we propose a novel timing synchronization method to construct a more viable full duplex MIMO link. By having the full duplex link prototype fully operating in real time, we present the first characterization of the proposed compact full duplex MIMO performance depending on the transmit power of the full duplex node. We also show the link quality between nodes. One of the crucial insights of this paper is that the full duplex operation of a user is capable of acquiring the throughput gain if the user has self-interference capability with guaranteed performance.
Principal Stress Model for Multi-Axial Fatigue of Preloaded Threaded Fasteners (2016)

A principal stress-based high cycle fatigue (HCF) model is proposed for cyclic multiaxial stresses in threaded fasteners under tensile-shear loading. The proposed model uses the fastener principle stress amplitude in order to construct mean-stress adjusted S-N curves for multi-axial stresses. Experimental validation is provided using an MTS fatigue testing system, with a special fixture that would allow combined cyclic tensile-shear loading of the fastener at various angles relative to the axis of the MTS grip axis. Experimentally validated multiaxial fatigue model is compared to classical uniaxial S-N curves. Detailed discussion of the model results is provided.
Identification of a novel glycoprotein (AGp110) involved in interactions of rat liver parenchymal cells with fibronectin. (1990)

We have identified an integral membrane glycoprotein in rat liver that mediates adhesion of cultured hepatocytes on fibronectin substrata. The protein was isolated by affinity chromatography of detergent extracts on wheat germ lectin-Agarose followed by chromatography of the WGA binding fraction on fibronectin-Sepharose. The glycoprotein (AGp110), eluted at high salt concentrations from the fibronectin column, has a molecular mass of 110 kD and a pI of 4.2. Binding of immobilized AGp110 to soluble rat plasma fibronectin required Ca2+ ions but was not inhibited by RGD peptides. Fab' fragments of immunoglobulins raised in rabbits against AGp110 reversed the spreading of primary hepatocytes attached onto fibronectin-coated substrata, but had no effect on cells spread on type IV collagen or laminin substrata. The effect of the antiserum on cell spreading was reversible. AGp110 was detected by immunofluorescence around the periphery of the ventral surface of substratum attached hepatocytes, and scattered on the dorsal surface. Immunohistochemical evidence and Western blotting of fractionated liver plasma membranes indicated a bile canalicular (apical) localization of AGp110 in the liver parenchyma. Expression of AGp110 is tissue specific: it was found mainly in liver, kidney, pancreas, and small intestine but was not detected in stomach, skeletal muscle, heart, and large intestine. AGp110 could be labeled by lactoperoxidase-catalyzed surface iodination of intact liver cells and, after phase partitioning of liver plasma membranes with the detergent Triton X-114, it was preferentially distributed in the hydrophobic phase. Treatment with glycosidases indicated extensive sialic acid substitution in at least 10 O-linked carbohydrate chains and 1-2 N-linked glycans. Immunological comparisons suggest that AGp110, the integrin fibronectin receptor and dipeptidyl peptidase IV, an enzyme involved in fibronectin-mediated adhesion of hepatocytes on collagen, are distinct proteins.
