A fast filter-bank for adaptive Fourier analysis (1998)

Adaptive Fourier analyzers have been developed for measuring periodic signals with unknown or changing fundamental frequency. Typical applications are vibration measurements and active noise control related to rotating machinery and calibration equipment that can avoid the changes of the line frequency by adaptation. Higher frequency applications have limitations since the computational complexity of these analyzers are relatively high as the number of the harmonic components to be measured (or suppressed) is usually above 50. In this paper, based on the concept of transformed domain signal processing, a fast filter-bank structure is proposed to reduce the above computational complexity. The first step of the suggested solution is the application of the filter-bank version of the fast Fourier transform or any other fast transformations that convert input data into the transformed domain. These fast transform structures operate as single-input multiple-output filter-banks, however, they can not be adapted since their efficiency is due to their special symmetry. As a second step, the adaptation of the filter-bank is performed at the transform structure's output by adapting a simple linear combiner to the fundamental frequency of the periodic signal to be processed.
Constructing Minimum Connected Dominating Sets with Bounded Diameters in Wireless Networks (2009)

Connected Dominating Sets (CDSs) can serve as virtual backbones for wireless networks. A smaller virtual backbone incurs less maintenance overhead. Unfortunately, computing a minimum size CDS is NP-hard, and thus most researchers in this area concentrate on how to construct smaller CDSs. However, people neglected other important metrics of network, such as diameter and average hop distances between two communication parties. In this paper, we investigate the problem of constructing quality CDS in terms of size, diameter, and Average Backbone Path Length (ABPL). We present two centralized algorithms having constant performance ratios for its size and diameter of the constructed CDS. Especially, the size of CDS computed by the second algorithm is no more than 6.906 times of its optimal solution. Furthermore, we give its distributed version, which not only can be implemented in real situation easily but also considers energy to extend network lifetime. In our simulation, we show that in average the distributed algorithm not only generates a CDS with smaller diameter and ABPL than related work but also suppresses its size well. We also show that it is more energy efficient than others in prolonging network lifetime.

Measurement of neuromuscular blockade in man (1977)

A simple modification of a clinical blood pressure transducer is described, which permits it to be used for the quantitative estimation of neuromuscular blockade in man. The instrument remains available for other pressure measurements since only the plastic dome is modified.
Anisotropic resistivity inversion (2003)

We present an inversion method for 3D electrical imaging in media with an inhomogeneous and anisotropic conductivity distribution. The conductivity distribution is discretized via finite elements and is described by a second-order tensor at each finite element node. The inversion method is formulated as a functional optimization with an error functional containing terms measuring data misfit and model covariance by means of smoothness, anisotropy and deviation from a starting model. Including the model covariance information overcomes the problem of ill-posedness at the expense of limiting the allowed models to the class of models which are compatible with the provided model covariance information. The discretized form of the error functional is minimized by a Levenberg–Marquardt type method using an iterative preconditioned conjugate gradient solver. The use of an iterative solver allows one to bypass the actual computation of the Jacobian or an inverse system matrix. The use of a memory efficient iterative solver together with the implementation on parallel computers allows large-scale inverse problems, comprising several hundred thousand nodes with hundreds of sources and receivers, to be solved. The new method is tested using computer-generated data from two- and three-dimensional synthetic models. For each inversion a choice of penalty parameters, gauging the level of model covariance information imposed, has to be made and the level of regularization required is hard to estimate. We find that running a suite of inversions with varying penalty parameters and subsequent examination of the results (including inspection of residual maps) offers a viable method for choosing appropriate numerical values for the penalty levels. In the applications we found the inversion process to be highly non-linear. Inversion models from intermediate steps of the iterative inversion show structure in places that do not exhibit structure in the true model and only at later iterations do anomalies move to the correct location in the modelling domain. This result indicates that linearized inversions that fail to re-linearize during the inversion process will fail to find meaningful inversion images. The inversion images achieved using the new method recover the important features of the true models, including the approximate magnitudes of the conductivity anomalies and the magnitudes and directions of anisotropy anomalies. The inversion images are generally 'blurred', that is sharp edges are smoothed, and the recovered magnitudes of conductivity, anisotropy and anisotropy direction are generally under-estimated.
A deficit in collagenase activity contributes to impaired migration of aged microvascular endothelial cells (2000)

Angiogenesis is impaired in aging. Delayed neovascularization is due, in part, to slowed endothelial cell migration. Migration requires an optimal level of adhesion to matrix proteins, a process mediated by matrix-degrading metalloproteases (MMPs) such as MMP1. To determine whether impaired angiogenesis in aging is associated with altered synthesis and activity of MMP1, we examined the expression of collagenase and tissue inhibitor of metalloprotease 1 (TIMP1) by immunostain of angiogenic sponge implants from young and aged mice. To characterize the relevance of MMP activity during the movement of aged endothelial cells, the secretion of MMP1 and TIMP1 by late-passage human microvascular endothelial cells (hmEC aged in vitro) and their non-aged (young) counterparts was quantified. The migration of aged human microvascular endothelial cells and the effect of inhibition of TIMP1 on the migration of aged hmEC or collagen I was also measured. Relative to young mice, granulation tissue from aged mice showed less expression of collagenase and increased expression of TIMP1. In vitro, aged hmEC were deficient in MMP1 secretion (55 +/- 13% relative to young cells) and activity but showed increased expression of TIMP1 (280 +/- 109% relative to young cells). Aged hmEC migrated significantly less distance than did young hmEC over a 5-day period (59 +/- 8% relative to young cells). In the presence of a blocking antibody to TIMP1, aged hmEC showed a significant increase in the distance migrated on collagen I over a 5 day period (142 +/- 11% relative to untreated aged hmEC). We propose that deficient MMP1 activity contributes to impaired cellular movement in aged microvascular endothelial cells and that perturbations that enhance collagenase activity increase their migratory ability and angiogenic potential.

HTS CroCo: A Stacked HTS Conductor Optimized for High Currents and Long-Length Production (2016)

In order to build high-current cables from second-generation high-temperature superconductor (HTS) rare-earth barium-copper-oxide (REBCO) tapes, numerous approaches were studied, such as conductor on round core, Roebel cable, and several versions of twisted stacked-tape cable types. Based on the work of Takayasu et al. and Uglietti et al., we developed and tested a modified type of stacked HTS tape arrangement optimized for high engineering critical current density. Key aspects were the implementation of a simple and reliable continuous fabrication routine for production of application-relevant lengths of twisted conductors in the range of 100 m and above and the subsequent enveloping by a seamless copper tube. Several samples of this HTS Cross-Conductor (HTS CroCo) were prepared successfully, both partially and fully equipped with REBCO tapes in untwisted and twisted configurations. The critical current of the samples was measured at T = 77 K and self-field conditions. The measurements showed the expected critical currents calculated from the individual tape values if taking into account the enhanced self-field in the tape arrangement. Furthermore, one untwisted partially REBCO-equipped sample was tested in the FBI facility at KIT at T = 4.2 K and in magnetic fields up to B = 12 T, showing good performance with no degradation even at high Lorentz forces. In addition, the mechanical performance of this sample was studied under tensile loads. No degradation could be observed, and the strain dependence was equal to that of single REBCO tapes. Due to the combination of excellent mechanical and electrical performance, the HTS CroCo is a promising candidate as a strand for long-length high-current cables, for example, with I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> (4.2 K, self-field) ≈ 30 kA for power transmission or with I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> (4.5 K, 14 T) ≈ 8 kA as a strand for high-current cables targeting large high-field magnets.
Adrenergic Receptors in Aging and Alzheimer's Disease: Increased β<sub>2</sub>‐Receptors in Prefrontal Cortex and Hippocampus (1989)

Abstract: Loss of pigmented noradrenergic locus ceruleus neurons occurs in Alzheimer's disease (AD) and, to a lesser extent, in aging. We studied β‐adrenergic receptors and their subtypes, β 1 and β 2 , by the specific binding of 125 I‐pindolol to particulate membrane preparations from prefrontal cortex, hippocampus, putamen, and cerebellum and to sections from frontal cortex by in vitro autoradiography. In prefrontal cortex from controls, numbers of total β‐ and β‐adrenoceptors did not significantly correlate with age, but number of β 1 ‐adrenoceptors showed a weak but significant negative correlation. Binding in tissue particulate preparations to total β‐receptors did not reveal significant differences in samples from prefrontal cortex between AD subjects and age‐matched controls. However, β 1 ‐adrenoceptors were decreased and β 2 ‐adrenoceptors were increased in number by ∼30‐50% in AD subjects. Thus, the relative ratio of β/β 2 ‐receptors was decreased in AD. Binding by in vitro receptor autoradiography performed in a subset of samples of frontal cortex also showed β 2 ‐adrenoceptors, and less consistently total β‐and β 1 recep‐tors, to be increased significantly in number in cortical laminae II, III, IV, and V of tissue sections from AD subjects. In these subjects, number of locus ceruleus cells and norepinephrine concentrations in putamen and frontal cortex were markedly reduced compared with values in controls. In the hippocampus, total β‐ and both β 2 ‐ and β 1 ‐adrenoceptors were increased in number in AD. In contrast, in the putamen. where β‐receptors predominate, total β‐ and β 1 ‐receptors were significantly decreased in number with no consistent change in content of β 2 ‐receptors in AD. There were no significant changes in the cerebellum. Specific pindolol binding was not affected by interval between death and sampling of tissue at autopsy. Our results indicate selective changes in number of β‐receptors in AD. These changes in the cortex and hippocampus suggest receptor upregulation in response to noradrenergic deafferentation from the locus ceruleus or may simply reflect glial proliferation in AD.
Absorption coefficients and exciton oscillator strengths in AlGaAs-GaAs superlattices (1985)

We have experimentally determined the absolute optical-absorption coefficients and exciton oscillator strengths in AlGaAs-GaAs superlattices at liquid-helium temperatures. We find that although the magnitude of the band-to-band absorption coefficient is essentially independent of the quantum-well width, the absorption coefficient due to exciton absorption is greatly enhanced as the well width becomes smaller. The absorption energies and exciton oscillator strengths are compared to theoretical calculations and shown to be in very good agreement. We find that the oscillator strength per unit volume is proportional to 1/${L}^{2}$ in narrow wells. The effects due to coupling between wells was also investigated by the comparison of structures with barriers of 100 A\r{} to those with barriers of only 25 A\r{}. The subband energies in the coupled wells decreased from their values in uncoupled wells in quantitative agreement with our calculations while the oscillator strength also decreased.
The Idle Mobile Resource Discovery and Management Scheme in Mobile Grid Computing Using IP-paging (2009)

In this paper, we tried to enable a mobile device as a resource to access to the grid network. By improved Internet technique, the use of mobile devices is rapidly increased. And some researches in grid computing tried to combine grid computing with mobile devices. However, according to properties of mobile environments, mobile devices have many considerations, such as mobility management, disconnected operation, device heterogeneity, service discovery, resource sharing, security and so on. To conquest these problems, there are two trends for mobile grid computing: a proxy-based mobile grid architecture and an agent-based mobile grid architecture. We focused on a proxy-based mobile grid architecture with IP-paging, which easily manage idle mobile devices and grid resource status information. In result, to support mobile grid services, we propose the IP-paging scheme based on the mobile grid computing framework. Moreover, we have discussed some research issues: location tracking using IP-paging, limited power using grid paging cache, and service migration using reserved resource. And, we also propose a mobile proxy and paging agent prototype.
Sub-$\hbox{100-}\mu\hbox{A}$ Reset Current of Nickel Oxide Resistive Memory Through Control of Filamentary Conductance by Current Limit of MOSFET (2008)

Resistive random access memory consisting of NiO resistive memories and control transistors was fabricated with 0.18-mum CMOS technology. An initial forming voltage as low as 2 V was achieved with thin NiO film, and a reset current lower than 100 muA was realized by using the current limit of a selected cell transistor in the set process (1T-1R). The current level was determined by its gate voltage, resulting in the control of electrical resistance of the filamentary conductive paths in the low resistive state. Furthermore, a large voltage increase in the reset operation, which may cause an undesirable set operation, was also suppressed by a voltage-clamp transistor connected to the 1T-1R cell in series. On the basis of these proposed switching schemes, the stable pulse operation was demonstrated successfully. In addition, both nonvolatile data retention at 150degC and operation in a wide temperature range (from -40degC to 150degC) were confirmed.
A Second Generation (High-Speed) Maximum Power Tracker for Space Applications (1968)

During the past few years, considerable effort has been exerted by both industry and government to improve the performance of space power systems. One of the significant advances has been the development of practical Maximum Power-Point Tracking (MPPT) systems. This paper presents the background and evolution of a second-generation (high-speed) MPPT system capable of operation with solar arrays with rapidly fluctuating parameters due to mission operation (e.g., spin-stabilized spacecraft). An experimental model of the high-speed MPPT system has been constructed and tested. Results from these tests are presented herein. The second-generation MPPT system provides a means of efficient power conditioning that can result in significant increases over conventional systems in space-power system capability. Of additional importance is the applicability of the basic technology to all types of spacecraft, and the wide variety of power-system configurations with which the high-speed MPPT system concept may be used.
Yours For Keeps: MGM v. Grokster, 23 J. Marshall J. Computer & Info. L. 209 (2005) (2005)

Millions of people download billions of music files over the Internet, using peer-to-peer ("P2P") services such as Grokster, StreamCast, Morpheus, and Kazaa. This practice has been challenged as violative of copyright and, it has been argued, the magnitude of copyright violations facilitated by P2P services justifies banning the services entirely. This argument has been based on the assumption that most transfers over P2P services violate copyright. The starting point for this discussion is the recent decision of the United States Supreme Court to grant the certiorari petition of Metro-Goldwyn-Mayer Studios et al. to review the Ninth Circuit decision in MGM v. Grokster. In that decision the Ninth Circuit affirmed the district court's grant of partial summary judgment in favor of Grokster, holding that Grokster did not materially contribute to the primary infringement and the software was being used to transfer a commercially significant number of non-infringing files. The author then proceeds in a more thourough examination of the established legal doctrines and the arguments posed by both sides. After a short presentation of the peer-to-peer (P2P)distribution technology by which files are transferred over the Internet but the information available for access does not reside on a central server, the author proceeds in exploring the basic assumption that most P2P transfers are infringing. Using the applicable principles of copyright law, those assumptions are analyzed and by applying current well-established law, two theories which contradict that assumption are identified: a significant number of individuals who transfer files over P2P networks may have a license to do so, and provisions of the Copyright Act itself may exempt the transfer of certain categories of entertainment files over P2P networks from the definition of infringement. Finally, the author concludes that since both sides agree that Sony v. Universal City Studios controls the issue, unless the Supreme Court decides to overturn Sony, or divines a third interpretation which the parties have not argued, no secondary liability for copyright infringement can be found under either of the two interpretations of Sony is chosen unless a substantial degree of primary liability, linked to the alleged secondary infringer, has been established.
Perinatal Loss of Ts65Dn Down Syndrome Mice (2005)

Ts65Dn mice inherit a marker chromosome, T(17(16))65Dn, producing segmental trisomy for orthologs of about half of the genes on human chromosome 21. These mice display a number of phenotypes that are directly comparable to those in humans with trisomy 21 and are the most widely used animal model of Down syndrome (DS). However, the husbandry of Ts65Dn mice is complicated. Males are sterile, and only 20-40% of the offspring of Ts65Dn mothers are trisomic at weaning. The lower-than-expected frequency of trisomic offspring has been attributed to losses at meiosis, during gestation and at postnatal stages, but no systematic studies support any of these suppositions. We show that the T(17(16))65Dn marker chromosome is inherited at expected frequency and is fully compatible with development to midgestation. Disproportional loss of trisomic offspring occurs in late gestation and continues through birth to weaning. Different maternal H2 haplotypes are significantly associated with the frequency of trisomy at weaning in patterns different from those reported previously. The proportion of trisomic mice per litter decreases with age of the Ts65Dn mother. These results provide the first statistical and numerical evidence supporting the prenatal and perinatal pattern of loss in the Ts65Dn mouse model of DS.
The effect of lactose and inulin on intestinal morphology, selected microbial populations and volatile fatty acid concentrations in the gastro-intestinal tract of the weanling pig (2006)

Abstract Twenty piglets (21 days, 7·8 kg live weight (LW)) were used in a 2×2 factorial to investigate interactions between lactose and inulin on intestinal morphology, microbiology and volatile fatty acid (VFA) production of the weanling pig. The piglets were offered the following diets for 6 days and then sacrificed: (T1) 150 g/kg lactose, (T2) 150 g/kg lactose +15 g/kg inulin, ( T3) 330 g/kg lactose, and ( T4) 330 g/kg lactose +15 g/kg inulin. Tissue samples were taken from the duodenum, jejunum and ileum for morphological measurements. Digesta samples were taken from the ileum, caecum and colon. There was an interaction ( P<0·05) between lactose and inulin in villous height in the jejunum. The inclusion of inulin at 150 g/kg lactose increased villous height compared with 150 g/kg lactose without inulin. However, inulin had no effect on villous height at 330 g/kg lactose inclusion. There was a linear relationship between food intake and villous height in the duodenum ( P <0·001, R 2 =0·45) and the jejunum ( P < 0·01, R 2 =0·25). The inclusion of 330 g/kg lactose increased ( P<0·05) total VFA compared with 150 g/kg lactose in the caecum and the population of lactobacilli in the caecum and colon ( P <0·1). There was an interaction ( P <0·05) between lactose and inulin for total VFA concentration in the colon. The pigs receiving 330 g/kg lactose had a higher total VFA concentration compared with pigs on 150 g/kg lactose. However, there was no difference between 150 g/kg and 330 g/kg lactose when the diets were supplemented with inulin. In conclusion, the inclusion of high dietary concentrations of lactose resulted in increased lactobacilli and short-chain fatty acid concentrations. The inclusion of inulin with low dietary concentrations of lactose resulted in improved intestinal health through a reduction of intestinal pH and increases in villous height.
