Register Queues: A New Hardware/Software Approach to Efficient Software Pipelining (2000)

In this paper we propose a new hardware mechanism, called Register Queues (RQs), which effectively decouples the architected register space from the physical registers. Using RQs, the compiler can allocate physical registers to store live values in the software pipelined loop while minimizing the pressure placed on architected registers. We show that decoupling the architected register space from the physical register space can greatly increase the applicability of software pipelining, even as memory latencies increase. Res combine the major aspects of existing rotating register file and register connection techniques to generate efficient software pipeline schedules. Through the use of RQs, we can minimize the register pressure and code expansion caused by software pipelining. We demonstrate the effect of incorporating register queues and software pipelining with 983 loops taken from the Perfect Club, the SPEC suites, and the Livermore Kernels.
문재인 정부 2년 반, 법치주의의 성과와 과제 (2019)

문재인 정부는 집권 초기에 높은 지지율을 보이면서 적폐청산, 검찰개혁, 사법개혁을 통한 법치발전을 추구했다. 하지만 임기의 절반이 지난 현시점에서 오히려 법치의 후퇴를 우려하는 목소리가 커지고 있다.
과연 문재인 정부 2년 반 동안 법치주의는 어떤 성과를 보였고, 과제를 남겼는가를 평가하기 위해 먼저 법치주의의 실현구조와 평가지표에 대해 간단히 정리한 후에 문재인 정부 2년 반 동안의 법치주의를 평가하기 위해 가장 대표적인 분야로 적폐청산, 검찰개혁, 사법개혁을 각기 검토해 보았다.
초기에 국민의 호응이 뜨거웠던 적폐청산은 적절한 시기에 적폐청산을 마무리하지 못함으로써 그 취지와 정당성이 퇴색되었다. 적폐청산의 의미와 방식 등에 대한 국민적 동의를 얻기 위한 노력이 부족했으며, 적용 대상 및 기준의 일관성이 결여됨으로써 동력을 상실하게 된 것이다.
검찰개혁은 현재진행형이다. 그러나 제1야당인 자유한국당의 강한 반대에 직면해 있을 뿐만 아니라, 공수처법의 내용에 대한 비판에도 불구하고 공수처를 도입하는 것이 곧 검찰개혁의 성공인것처럼 주장하는 것은 타당하지 않다.
사법개혁은 아직도 과제로 남아 있다. 하지만 대법원에서 마련된 사법행정회의 안에 대해서는 전문가들의 비판이 매우 날카로우며, 법원 내부에서의 이견도 적지 않은 것으로 알려지고 있다.
이러한 법치 분야의 성과가 충분치 못하다는 것만으로 문재인 정부를 전체적으로 평가하기는 어렵다. 그러나 주목할 점은 민주정치와 법치가 상호 의존적이라는 점이다. 민주적 정치과정을 통해 법이 만들어지지만, 이렇게 만들어진 법은 정치과정을 통제한다. 이러한 상호 의존 및 상호 통제를 통해 정치와 법치는 올바른 방향으로 나아갈 수 있기 때문이다.
법치를 도외시한 정치는 독재정치 또는 중우정치에 빠지기 쉽다. 설령 민주주의에 투철한 정치인들이라 할지라도 자신도 모르는 사이에 포퓰리즘의 늪에 빠지기 쉽다. 문재인 정부도 이제는 스스로를 돌아보면서 점점 치열해지는 정치적 갈등 속에서 법치가 올바른 방향을 제시하지 못하고 있다는 점을 인식하면서 이를 해결하는 것은 남은 임기 동안의 가장 중요한 과제의 하나로 삼아야 할 것이다.
Intelligent control of large power transformer cooling pumps (1996)

The paper describes a novel approach to the control of large power transformer cooling. An intelligent controller is proposed taking elements of fuzzy logic and neural networks, together with recent advances in sensor technologies. This controller drives the cooling system to operate in flow and temperature regimes which limit the problem of streaming electrification while minimising thermal degradation of the insulation. A simplified example is given to demonstrate the viability of the proposed controller.

The Calcium-binding Proteins S100A8 and S100A9 Initiate the Early Inflammatory Program in Injured Peripheral Nerves (2015)

To shed light on the early immune response processes in severed peripheral nerves, we performed genome-wide transcriptional profiling and bioinformatics analyses of the proximal (P, regenerating) and distal (D, degenerating) nerve stumps on day 1 in the sciatic nerve axotomy model in rats. Multiple cell death-related pathways were activated in the degenerating D stump, whereas activation of the cytoskeletal motility and gluconeogenesis/glycolysis pathways was most prominent in the P stump of the axotomized nerve. Our bioinformatics analyses also identified the specific immunomodulatory genes of the chemokine, IL, TNF, MHC, immunoglobulin-binding Fc receptor, calcium-binding S100, matrix metalloproteinase, tissue inhibitor of metalloproteinase, and ion channel families affected in both the P and D segments. S100a8 and S100a9 were the top up-regulated genes in both the P and D segments. Stimulation of cultured Schwann cells using the purified S100A8/A9 heterodimer recapitulated activation of the myeloid cell and phagocyte chemotactic genes and pathways, which we initially observed in injured nerves. S100A8/A9 heterodimer injection into the intact nerve stimulated macrophage infiltration. We conclude that, following peripheral nerve injury, an immediate acute immune response occurs both distal and proximal to the lesion site and that the rapid transcriptional activation of the S100a8 and S100a9 genes results in S100A8/A9 hetero- and homodimers, which stimulate the release of chemokines and cytokines by activated Schwann cells and generate the initial chemotactic gradient that guides the transmigration of hematogenous immune cells into the injured nerve.
A High Resolution and Full-Spherical Head-Related Transfer Function Database for Different Head-Above-Torso Orientations (2017)

Head-related transfer functions (HRTFs) were acoustically measured and numerically simulated for the FABIAN head and torso simulator on a full-spherical and high resolution sampling grid. Moreover, HRTFs were acquired for 11 horizontal head-above-torso orientations, covering the typical range of motion of 50
Decentralized Massive MIMO Systems: Is There Anything to be Discussed? (2019)

Algorithms for Massive MIMO uplink detection are typically based on a centralized approach, by which baseband data from all antenna modules need to be routed to a central node for further processing. In the case of Massive MIMO, where hundreds or thousands of antennas are expected in the base-station, such architecture requires high interconnection bandwidth between antennas and the central node. Recently, decentralized architectures have been proposed to maintain low interconnection bandwidth, where channel-state-information (CSI) is obtained locally in each antenna node and not shared. Further, Massive MIMO performance is sensitive to CSI quality. However, in the literature, ideal CSI is typically assumed in decentralized systems, which is not only far from reality but also limits the generality of the analysis.This paper proposes a decentralized (a term that will be defined in the main body of the paper) architecture with the following main features: (i) the channel matrix is not made available at any single node, (ii) there is no inter-communication among antennas, (iii) the architecture used during the payload data phase, is reused to provide a certain statistic to a processing node, (iv) A non-standard channel estimation problem based on said statistic arises, (v) a matrix inversion is needed (in case of zero-forcing) at said processing node.A hefty share of the paper is devoted to (iv).
Flow behavior of petrol, bio-ethanol and their blends (2013)

The objective of this article deals with the flow behavior of bio-ethanol, conventional petrol and their blends (E15, E85). The temperature dependence density and kinematic viscosity of the liquids have been measured. The densitometer Densito 30PX with the scale for measuring fuels has been used to the measuring temperature dependence of the density of fuels and their blends. The rotary viscometer Anton Paar DV-3P has been used to the measuring temperature dependence of kinematic viscosity of fuels and their blends. For all samples has determined that the temperature has increased the density and kinematic viscosity of fuels and their blends has decreased. The range of temperature measurement has been from -10Â°C to 40Â°C. The mathematic models have been compiled (polynomial and exponential) according to the general shapes. The coefficients of determination R2 have achieved high values from 0.98 to 0.99 for temperature dependence of density of fuels and their blends and from 0.86 to 0.96 for temperature dependence of kinematic viscosity of fuels and their blends. The mathematical models could be used to the prediction flow behavior of petrol, bio-ethanol and their blends.
Disodium cromoglycate in the treatment of ulcerative colitis and Crohn's disease. (1981)

A controlled clinical study on disodium cromoglycate (DSCG) at a dose of 800 mg per day versus placebo was carried out in 141 patients with ulcerative colitis and 25 patients with Crohn's disease. Those of the ulcerative colitis patients who had been on sulphasalazine treatment continued that treatment during the trial (101 patients). Forty patients were intolerant of sulphasalazine. No patient received steroids during the last month before the study. Patients with Crohn's disease had their possible sulphasalazine treatment stopped before the trial. No beneficial effect of DSCG as compared with placebo was found, as the DSCG and the placebo group showed the same number of relapses in patients with a clinically inactive ulcerative colitis at the start of the trial and the same number of patients improving, deteriorating, and maintaining steady state in patients with clinically active ulcerative colitis at the start of the trial. There was no difference between relapse rate in DSCG and placebo groups in patients with Crohn's disease. No correlation between the eosinophil count in rectal mucosa and the outcome of the attack of ulcerative colitis could be demonstrated.
Pachychalines A–C: Novel 3‐Alkylpyridinium Salts from the Marine Sponge <i>Pachychalina</i> sp. (2007)

Abstract Three 3‐alkylpyridinium salts, pachychalines A ( 1 ), B ( 2 ) and C ( 3 ), were isolated from the Caribbean marine sponge Pachychalina sp. (order Haplosclerida). They are the first examples of 3‐(aminoalkyl)pyridinium salts. Their chemical structures were elucidated by NMR spectroscopy and detailed ESI HRMS–MS analysis. The total synthesis of 1 allowed the confirmation of the unusual C–C connection between both pyridinium moieties. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Control of Complex Components with Smart Flexible Phased Arrays (2006)

The inspection of piping in nuclear plants is mainly performed in contact with ultrasonic wedge transducers. During the scanning, the fixed shape of wedges cannot fit the irregular surfaces and complex geometries of components (butt weld, nozzle, elbow). The variable thickness of the coupling layer, between the wedge and the local surface, leads to beam distortions and losses of sensitivity. Previous studies have shown that these two phenomena contribute to reduce the inspection performances leading to shadow area, split beam. To improve such controls, a new concept of contact “Smart Flexible Phased Array” has been developed with the support of the French “Institut de Radioprotection et de Sûreté Nucléaire”. The phased array is flexible to fit the complex profile and to minimize the thickness of the coupling layer. The independent piezoelectric elements composing the radiating surface are mechanically assembled in order to build an articulated structure. A profilometer, embedded in the transducer, measures the local surface distortion allowing to compute in real‐time the optimized delay laws and compensating the distortions of 2D or 3D profiles. Those delay laws are transferred to the real‐time UT acquisition system, which applies them to the piezoelectric elements. This self‐adaptive process preserves, during the scanning, the features of the focused beam (orientation and focal depth) in the specimen. To validate the concept of the Smart Flexible Phased Array Transducer, two prototypes have been integrated to detect flaws machined in mock‐ups with realistic irregular 2D and 3D shapes. Inspections have been carried out on samples showing the enhancement performances of the “Smart Flexible Phased Array” and validating the mechanical and acoustical behaviours of these probes.
Loss of Phosphatase and Tensin Homolog or Phosphoinositol-3 Kinase Activation and Response to Trastuzumab or Lapatinib in Human Epidermal Growth Factor Receptor 2–Overexpressing Locally Advanced Breast Cancers (2010)

Activation of PI3 kinase pathway is associated with trastuzumab resistance, whereas low PTEN predicted for response to lapatinib. These observations support clinical trials with the combination of both agents.
<i>N</i>-(4-Chlorophenyl)-<i>N</i>-hydroxy-<i>N</i>′-(3-chlorophenyl)urea, a general reducing agent for 5-, 12-, and 15-lipoxygenases and a substrate for their pseudoperoxidase activities (1992)

Lipoxygenases contain a nonheme iron that undergoes oxidation and reduction during the catalytic cycle. The conversion from the Fe3+ enzyme form to the Fe2+ form can be achieved using reducing inhibitors, a reaction that can be reversed with lipid hydroperoxides. The present study describes the properties of N-(4-chlorophenyl)-N-hydroxy-N'-(3-chlorophenyl)urea (CPHU), which functions as a reducing agent for various lipoxygenases and stimulates the degradation of lipid hydroperoxide catalyzed by these enzymes (pseudoperoxidase activity). CPHU was a substrate for the pseudoperoxidase reaction of purified soybean lipoxygenase-1 with apparent Km values for CPHU and 13-hydroperoxy-9,11-octadecadienoic acid (13-HpODE) of 14 and 15 microM, respectively. CPHU was converted during the pseudoperoxidase reaction to a mixture of products that can be resolved by reverse-phase high pressure liquid chromatography. By comparison with the chemical reaction of CPHU and potassium nitrosodisulfonate, the major enzymatic reaction product was tentatively identified as a one-electron oxidation product of CPHU. At low concentrations (50 microM), dithiothreitol completely protected against the degradation of hydroxyurea without inhibiting the pseudoperoxidase reaction. Under these conditions, the rate of the pseudoperoxidase reaction with CPHU as a substrate can be quantitated by the change in absorbance at 234 nm owing to the consumption of 13-HpODE. In addition to soybean lipoxygenase-1, CPHU was found to be a substrate for the pseudoperoxidase activities of purified recombinant human 5-lipoxygenase and porcine leukocyte 12-lipoxygenase. The results are consistent with CPHU reacting with lipoxygenase by a one-electron oxidation to generate the ferrous enzyme form and the nitroxide radical, which could be reduced back to CPHU by DTT.(ABSTRACT TRUNCATED AT 250 WORDS)
Alpha 1 antitrypsin phenotypes and alcoholic pancreatitis. (1991)

Altered frequencies of alpha 1 antitrypsin phenotypes have been reported in patients with chronic pancreatitis, suggesting a possible genetic basis for individual susceptibility to this disease. Alpha 1 antitrypsin phenotypes, with particular regard to alcoholic pancreatitis, were studied. Patients with alcoholic pancreatitis were compared with alcoholic control subjects with no history of pancreatic disease. Serum alpha 1 antitrypsin concentrations were raised in pancreatitis patients sampled within one month of an acute attack of pancreatitis, but otherwise values were similar to those of control subjects. There were no significant differences in alpha 1 antitrypsin phenotypes between alcoholics with pancreatitis and alcoholic control subjects. This study of alpha 1 antitrypsin phenotypes provides no evidence of an inherited susceptibility to alcoholic pancreatitis.
Teletraffic models for urban and suburban microcells: cell sizes and handoff rates (1993)

As cellular systems evolve into personal communication networks, teletraffic modeling of users will become crucial. Teletraffic models are required for cellular system layout and planning and to evaluate tradeoffs in system design issues. The paper begins with a study of handoff rates in evolving cellular systems. Using simple geometry, it shows that in macrocells with homogeneous traffic the handoff rate per call increases only as the square-root of the increase in the call density. The situation is different in microcells where individual traffic paths become important and the homogeneous traffic model does not apply. Under smooth flow, the handoff rate along a traffic path goes up linearly with the number of new boundaries intersecting the path. Hence, in urban and highway microcells the handoff rate per call increases linearly with increasing call density. It proposes a parametric model based on results from vehicular traffic theory, that applies to vehicles and pedestrians in urban, suburban, and highway cellular systems. The model helps quantify various design tradeoffs. With reasonable parameter values, it was found that microcells are unnecessary in urban environments if the pedestrian penetration is small and that an architecture with microcells and overlaid macrocells is required only if a majority of teletraffic is pedestrian generated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
ScanSAR focusing and interferometry (1996)

The authors discuss an efficient phase preserving technique for ScanSAR focusing, used to obtain images suitable for ScanSAR interferometry. Given two complex focused ScanSAR images of the same area, an interferogram can be generated as for conventional repeat pass SAR interferometry. However, due to the nonstationary azimuth spectrum of ScanSAR images, the coherence of the interferometric pair and the interferogram resolution are affected, both by the possible scan misregistration between two passes and by the terrain slopes along the azimuth. The resulting decorrelation can be significantly reduced by means of an azimuth varying filter, provided that some conditions on the scan misregistration are met. Finally, the SAR-ScanSAR interferometry is proposed: here the decorrelation can always be removed. With no resolution loss by means of the technique presented.
Cobalt salt-catalyzed carbocyclization reactions of α-bromo-N-phenylacetamide derivatives (2017)

An efficient and low-cost method for the synthesis of 4-substituted quinolin-2-(1H)-ones has been developed. In the presence of TBHP, the cobalt(ii)-catalyzed carbocyclization reactions of arylethenyl substituted α-bromo-N-phenylacetamides, involving sequential 6-exo-trig radical cyclization, t-butylperoxy radical cross-coupling reaction and the base-promoted ionic Kornblum-DeLaMare reaction, produced 4-benzoylquinolin-2-(1H)-ones. A variety of useful functional groups such as methoxy, fluoro, chloro, bromo, methoxycarbonyl, and cyano groups, are compatible with the reaction conditions. This strategy was further applied to arylethynyl substituted α-bromo-N-phenylacetamides, and 4-benzylquinolin-2-(1H)-ones were formed effectively.
A Convenient Synthesis of Two New Indoloquinoline Alkaloids (1997)

A concise synthesis of two new indoloquinoline-based alkaloids (1 and 2), isolated from Cryptolepis sanguinolenta, is reported. The palladium-catalyzed cross-coupling reaction of 3-bromoquinoline derivatives with N-pivaloylamine phenylboronic acid gave the corresponding biaryls from which the indoloquinoles could be synthesized.
Rare-earth doped optical fibers for temperature sensing (1992)

The feasibility of using a variety of rare-earth doped optical fibers for measuring spatially averaged temperatures from approximately 0 to approximately 100 degrees C over distances of 10 to 20 m is discussed. Such distributed temperature sensors would be particularly well-suited for building climate control systems and industrial processing applications. The temperature-dependent absorption spectra of 6 MCVD processed fibers containing different concentrations of Nd/sup 3+/, Pr/sup 3+/, and Yb/sup 3+/ rare-earth ions were characterized and used to determine thermally active dopant species, optimal dopant concentrations, and most sensitive operating wavelengths for use as dual wavelength distributed temperature sensors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bilinear Generalized Approximate Message Passing—Part II: Applications (2014)

In this paper, we extend the generalized approximate message passing (G-AMP) approach, originally proposed for high-dimensional generalized-linear regression in the context of compressive sensing, to the generalized-bilinear case. In Part I of this two-part paper, we derived our Bilinear G-AMP (BiG-AMP) algorithm as an approximation of the sum-product belief propagation algorithm in the high-dimensional limit, and proposed an adaptive damping mechanism that aids convergence under finite problem sizes, an expectation-maximization (EM)-based method to automatically tune the parameters of the assumed priors, and two rank-selection strategies. Here, in Part II, we discuss the specializations of BiG-AMP to the problems of matrix completion, robust PCA, and dictionary learning, and present the results of an extensive empirical study comparing BiG-AMP to state-of-the-art algorithms on each problem. Our numerical results, using both synthetic and real-world datasets, demonstrate that EM-BiG-AMP yields excellent reconstruction accuracy (often best in class) while maintaining competitive runtimes.
Euclidean and fractal models for the description of rock surface roughness (1991)

Accurate description of the topography of rock surfaces is essential because surface roughness affects frictional strength, the flow of fluids in joints and fractures, the seismic behavior of faults, and the formation of gouge and breccia in fault zones. Real rock surfaces can be described using self‐similar and self‐affine fractal models of surface roughness. If a surface is self‐similar, a small portion of the surface, when magnified isotropically, will appear statistically identical to the entire surface. If a surface is self‐affine, a magnified portion of the surface will only appear statistically identical to the entire surface if different magnifications are used for the directions parallel and perpendicular to the surface. At least two parameters are required to describe a fractal model; one parameter typically describes how roughness changes with scale, while the other specifies the variance or surface slope at a reference scale. The divider method and the spectral method are in common use to determine the best fit fractal model from surface profile data. Power spectra from self‐similar surfaces have slopes of −3 on log‐log plots of power spectral density versus spatial frequency, while spectra from self‐affine surfaces have slopes other than −3. Power spectra can be interpreted with greater facility if dimensionless amplitude to wavelength ratios are contoured on plots of power spectral density versus frequency. The topography of many natural rock surfaces, including both fractures and faults, is approximately self‐similar within the 6.5 order of magnitude wide wavelength band of 10 μm to 40 m. Within smaller wavelength bands, natural rock surfaces may exhibit self‐affine behavior.
A frequency agile microstrip antenna (2005)

This paper describes a novel technique for increasing the operational frequency bandwidth of microstrip patch antennas, by using varactor diodes at the radiating edges of the structure. Theoretical and experimental results confirm that bandwidths of the order of 30% are achievable compared to 1-2% for the unloaded patch radiator.
