The Method and Tool of Cost Analysis for Cloud Computing (2009)

Proposal of cloud computing is tightly coupled with low cost. Reduction of cost is considered as an important advantage of cloud. However, there are no available tools proper for cost calculation and analysis in Cloudenvironment. This paper presents our efforts towards filling in the gap. We format suits of metrics and formulas for the calculation of Cloud Total Cost of Ownership(TCO) and Utilization Cost, considering the elastic feature of Cloud infrastructure and widely adopted virtualization technology in Cloud. This provides afoundation for evaluating economic efficiency of Cloud and provides indications for cost optimization of Cloud.We have developed our calculation and analysis approach into a web tool which is used in the internal Cloud environment and demonstrate initially its analysis capability on the cost distribution and utilization imbalance factor.
Preliminary observations on the pathogenesis of experimental bovine spongiform encephalopathy (BSE): an update (1998)

Further preliminary observations are reported of an experiment to examine the spread of infectivity and the occurrence of pathological changes in cattle exposed orally to infection with bovine spongiform encephalopathy. Calves were dosed at four months of age and clinically monitored groups were killed sequentially from two to 40 months after inoculation. Tissues were collected for bioassay, for histopathological examinations and for the detection of PrP. Previous reported observations have included the presence of infectivity in the distal ileum of cattle killed after six to 18 months, the earliest onset of clinical signs in an exposed animal after 35 months, and diagnostic histopathological changes in the brain, in association with clinical disease, after 36, 38 and 40 months. In spite of the relative inefficiency of the bioassay of scrapie-like agents across a species barrier the new observations confirm that the onset of clinical signs and pathological changes in the central nervous system (CNS) occur at approximately the same time. The earliest pathological change, the presence of abnormal PrP 32 months after inoculation, coincided with the earliest detected infectivity in the CNS and occurred shortly before there was evidence of typical spongiform changes in the brain 36 months after inoculation. Infectivity has now been demonstrated in the peripheral nervous system, in the cervical and thoracic dorsal root ganglia 32 to 40 months after inoculation and in the trigeminal ganglion 36 and 38 months after inoculation. At the time of writing evidence of infectivity in other tissues is confined to the distal ileum, not only after six to 18 months but also after 38 and 40 months, but these findings may be supplemented by the results of further mouse assays. Nevertheless, they are in general agreement with current knowledge of the pathogenesis of scrapie.
Neural Control of Immunity in Hypertension: Council on Hypertension Mid Career Award for Research Excellence, 2019 (2020)

The nervous system and the immune system share the common ability to exert gatekeeper roles at the interfaces between internal and external environment. Although interaction between these 2 evolutionarily highly conserved systems has been recognized for long time, the investigation into the pathophysiological mechanisms underlying their crosstalk has been tackled only in recent decades. Recent work of the past years elucidated how the autonomic nervous system controls the splenic immunity recruited by hypertensive challenges. This review will focus on the neural mechanisms regulating the immune response and the role of this neuroimmune crosstalk in hypertension. In this context, the review highlights the components of the brain-spleen axis with a focus on the neuroimmune interface established in the spleen, where neural signals shape the immune response recruited to target organs of high blood pressure.
RUMBLE: An Incremental Timing-Driven Physical-Synthesis Optimization Algorithm (2008)

Physical-synthesis tools are responsible for achieving timing closure. Starting with 130-nm designs, multiple cycles are required to cross the chip, making latch placement critical to success. We present a new physical-synthesis optimization for latch placement called Rip Up and Move Boxes with Linear Evaluation (RUMBLE) that uses a linear timing model to optimize timing by simultaneously replacing multiple gates. RUMBLE runs incrementally and in conjunction with static timing analysis to improve the timing for critical paths that have already been optimized by placement, gate sizing, and buffering. Experimental results validate the effectiveness of the approach: Our techniques improve slack by 41.3% of cycle time on average for a large commercial ASIC design.
Peroxisome Proliferator-Activated Receptor-γ and Its Coactivator-1α Gene Polymorphisms in Korean Women with Polycystic Ovary Syndrome (2010)

Neither the PPAR-gammaPro12Ala nor the PGC-1alpha Gly482Ser polymorphism were supposed to be susceptible genes in PCOS. However, in PCOS patients, the PPAR-gammaPro12Ala and the PGC-1alpha Gly482Ser polymorphism may modulate the concentrations of serum HDL levels and postprandial 2-hour insulin level, respectively.
Smart Disc - Application in an ASML wafer stepper (2001)

High-precision machines typically suffer from small, but annoying, badly damped vibrations. In case such a vibration problem can not be solved passively, a solution may be found in active vibration control. In this respect, research at the Drebbel Institute is aimed at the development of a device called SMART DISC (SD). It is envisioned as an active structural element, consisting of a piezoelectric position actuator co-located with a piezoelectric force sensor, and control and amplifier electronics. As an industrial, three-dimensional test set-up for evaluation of the performance of SD&amp;apos;s, the lens support of an ASML wafer stepper has been chosen. By inserting SD&amp;apos;s in the lens support, and applying Integral Force Feedback control, the relative tilt of the lens relative to the main plate has been reduced by more than a factor 3. The absolute acceleration level of the top of the lens at its dominant resonance frequency has been successfully reduced to less than 10% of the original level. Proc.

Correspondence (1997)

A patent foramen ovale (PFO) may cause recurrent paradoxical embolism with stroke or occlusion of the peripheral arterial system. The incidence of PFO in a young population suffering from stroke is higher than 50% [1,2]. Until recent years, the classical treatment of PFO included either anticoagulation or surgical closure. Currently, transcatheter closure of atrial septal defects has been offered to these patients as a less invasive therapeutical option [3,4]. However, exact placement of the device may be challenging and incomplete closure of the atrial septum may not eradicate the risk of recurrent embolism. We report a puzzling case of a 41 year old patient with a complex cardiovascular past history, including thromboangiitis obliterans Buerger of the lower left extremity treated by lumbal sympathectomy as well as recurrent peripheral arterial and cerebral embolisms, documented by chronic and more fresh lesions in the magnetic resonance imaging of the brain. Transesophageal contrast echocardiography demonstrated a small defect in the atrial septum—corresponding to a PFO—and the presence of a right-to-left shunt through it during a Valsalva manoeuvre. No intracardiac source of embolism was found and there was no significant atherosclerosis of the ascending aorta and the aortic arch; doppler-duplex examination did not demonstrate any extracranial stenotic cerebrovascular disease and also no deep venous thrombosis of the lower extremities. However, paradoxical embolism was thought to be the most probable cause of the stroke episodes and of the peripheral ischemia. Anticoagulation with coumadin was instituted and the PFO was closed by transcatheter technique using an inverted Sideris buttoned device (Fig. 1). At the end of the intervention, the part of the main occluder—localised in the right atrium—dislocated and embolized into the right pulmonary artery. This part of the device could be removed using a retrieval basket. The other part of the device—called counter-occluder—remained attached on the left side of the atrial septum. At the end of the
Learning Riemannian Metrics for Classification of Dynamical Models (2005)

Consider the problem of classifying motions, encoded as dynamical models of a certain class. Standard nearest neighbor classification then reduces to find a suitable distance function in the space of the models. In this paper we present a supervised differential-geometric method to learn a Riemannian metric for a given class of dynamical models in order to improve classification performances. Given a training set of models the optimal metric is selected among a family of pullback metrics induced by the Fisher information tensor through a parameterized diffeomorphism. Experimental results concerning action and identity recognition based on simple scalar features are shown, proving how learning a metric actually improves classification rates when compared with Fisher geodesic distance and other classical distance functions.
Orthorhombic anisotropy; a physical seismic modeling study (1991)

Abstract An industrial laminate, Phenolic CE, is shown to possess seismic anisotropy. This material is composed of laminated sheets of canvas fabric, with an approximately orthogonal weave of fibers, bonded with phenolic resin. It is currently being used in scaled physical modeling studies of anisotropic media at The University of Calgary. Ultrasonic transmission experiments using this material show a directional variation of compressional- and shear-wave velocities and distinct shear-wave birefringence, or splitting. Analysis of group-velocity measurements taken for specific directions of propagation through the material demonstrates that the observed anisotropy is characteristic of orthorhombic symmetry, i.e., that the material has three mutually orthogonal axes of two-fold symmetry. For P waves, the observed anisotropy in symmetry planes varies from 6.3 to 22.4 percent, while for S waves it is observed to vary from 3.5 to 9.6 percent.From the Kelvin-Christoffel equations, which yield phase velocities given a set of stiffness values, expressions are elaborated that yield the stiffnesses of a material given a specified set of group-velocity observations, at least three of which must be for off-symmetry directions.
Compressive stress-strain behaviour of cast dental restorations in relation to luting cement distribution (2006)

This work is concerned with the performance, under dynamic compression, of the adhesives used to simulate cementation of gold crowns onto nickel chromium dies. A measurement system, based on the mounting of strain gauges onto the outer surface of the crowns, has been developed, which allows a semi-quantitative estimate of the state of adhesion. A preliminary study was carried out where miniature gauges were bonded onto the buccal, lingual, mesial and distal surfaces of gold crowns cast to fit onto a chromium-cobalt die, as a precursor to the final design of the instrumented crown. The crowns were then loaded in compression periodically measuring the strain at all four gauges. The results showed the load-strain relationship in fully, partially and uncemented crowns, along with repeated load-unload behaviour to close to the ultimate strength of the bond. The load-strain relationship is linear and repeatable and the slope varies over a factor of about 30 between the un-cemented and fully cemented crown, demonstrating that there is significant sensitivity to bond integrity. These results were used to determine the parameters for a systematic study of S-N relationships in restorative dentistry crowns.
Duration of filgrastim mobilization and apheresis yield of CD34+ progenitor cells and lymphoid subsets in normal donors for allogeneic transplantation (1996)

Seventy-seven normal donors underwent leukapheresis for peripheral blood progenitor cell collection beginning on day 4 (n = 45) or day 5 (n = 32) of filgrastim mobilization (12 micrograms/kg/d). The two groups were comparable for age, weight, blood volumes processed during leukapheresis and target CD34+ cell dose to be collected. The day 5 schedule allowed a more consistent achievement of the target cell dose with one apheresis (P = 0.005) and resulted in the initial collection of a significantly larger number of CD34+ cells (P = 0.009). There was no statistically significant difference in the leukapheresis yield of lymphoid subsets and natural killer cells.

Multiresolution hierarchical blind recovery of biochemical markers of brain cancer in MRSI (2005)

We present a multi-resolution hierarchical application of the constrained non-negative matrix factorization (cNMF) algorithm for blindly recovering constituent source spectra in magnetic resonance spectroscopic imaging (MRSI). cNMF is an extension of non-negative matrix factorization (NMF) that includes a positivity constraint on amplitudes of recovered spectra. We apply cNMF hierarchically, with spectral recovery and subspace reduction constraining which observations are used in the next level of processing. The decomposition model recovers physically meaningful spectra which are highly tissue-specific, for example spectra indicative of tumor proliferation, given a processing hierarchy that proceeds coarse-to-fine. We demonstrate the decomposition procedure on /sup 1/H long TE brain MRS data. The results show recovery of markers for normal brain tissue, low proliferative tissue and highly proliferative tissue. The coarse-to-fine hierarchy also makes the algorithm computationally efficient, thus it is potentially well-suited for use in diagnostic work-up.
MATERIAL CLASSIFICATION SYSTEM: LITERATURE SURVEY (2020)

One of the chief challenges faced today is determining the material category of a surface from an image. From the results obtained from several studies on object detection and image classification using Convolutional Neural Networks (CNNs), it is possible to study the material classification of everyday objects. The following intensive literature survey enables us to understand the various techniques developed to overcome the challenges.
Effect of longwall-induced subsurface deformations on shale gas well casing stability under deep covers (2018)

This paper presents the results of a 2017 study conducted by the National Institute for Occupational Safety and Health (NIOSH), Pittsburgh Mining Research Division (PMRD), to evaluate the effects of longwall-induced subsurface deformations within a longwall abutment pillar under deep cover. The 2017 study was conducted in a southwestern Pennsylvania coal mine, which extracts 457 m-wide longwall panels under 361 m of cover. One 198 m-deep, in-place inclinometer monitoring well was drilled and installed over a 45 m by 84 m center abutment pillar. In addition to the monitoring well, surface subsidence measurements and underground coal pillar pressure measurements were conducted as the 457 m-wide longwall panel on the south side of the abutment pillar was being mined. Prior to the first longwall excavation, a number of simulations using FLAC3D™ were conducted to estimate surface subsidence, increases in underground coal pillar pressure, and subsurface horizontal displacements in the monitoring well. Comparisons of the pre-mining FLAC3D simulation results and the surface, subsurface, and underground instrumentation results show that the measured in-place inclinometer casing deformations are in reasonable agreement with those predicted by the 3D finite difference models. The measured surface subsidence and pillar pressure are in excellent agreement with those predicted by the 3D models. Results from this 2017 research clearly indicate that, under deep cover, the measured horizontal displacements within the abutment pillar are approximately one order of magnitude smaller than those measured in a 2014 study under medium cover.

Dynamic Software-Defined Resource Optimization in Next-Generation Optical Access Enabled by OFDMA-Based Meta-MAC Provisioning (2013)

In order to address a diverse and demanding set of service and network drivers, several technology candidates with inherent physical layer (PHY) differences are emerging for future optical access networks. To overcome this PHY divide and enable both cost and bandwidth efficient heterogeneous technology co-existence in future optical access, we propose a novel Orthogonal Frequency Division Multiple Access (OFDMA)-based “meta-MAC”, which encapsulates PHY variations and enables fair inter-technology bandwidth arbitration. The new software-defined meta-MAC is envisioned to work on top of constituent MAC protocols, and exploit virtual OFDMA subcarriers as both finely granular and scalable bandwidth assignment units. We introduce important OFDMA meta-MAC design principles, and propose an elaborate three-stage dynamic resource provisioning scheme that satisfies the key requirements. The performance benefits of the meta-MAC concept and the proposed dynamic resource provisioning schemes in terms of spectrum management flexibility and support of diverse services are verified via real-time traffic simulation, confirming the attractiveness of the new approach for future optical access systems.
Paleomagnetism of mesozoic red chert from Cedros Island and the San Benito Islands, Baja California, Mexico revisited (1992)

Previous paleomagnetic study of Mesozoic subduction‐complex rocks on Cedros Island and the San Benito Islands, Mexico, shows that these rocks have been remagnetized; a single‐polarity magnetization was found in chert sections and underlying pillow basalt deposited during a mixed‐polarity interval of the geomagnetic field. Reanalysis of the Cedros and San Benito chert samples (101 total) shows that 13 samples also retain a high blocking‐temperature component of magnetization (600° to 680°C) indicating a polarity stratigraphy and deposition of the bedded chert near 2° ± 3° paleolatitude. These data are similar to those for red chert in California and Japan implying that many of the Mesozoic ophiolitic chert sequences now exposed around the Pacific rim were initially deposited within the equatorial zone of high biologic productivity. These new data also support accretion of the Cedros and San Benito chert to the American margin at tropical paleolatitudes requiring significant northward translation (and clockwise rotation) to bring them to their present position with respect to the continental interior.
Decomposing power measurements for mobile devices (2010)

Modern mobile phones are an appealing platform for pervasive computing applications. However, the complexity of these devices makes it difficult for developers to understand the power consumption of their applications. Our measurement framework is the first we have seen which can produce fine-grained, annotated traces of a phone's power consumption and is designed to develop an understanding of how particular aspects of an application drive energy use. We are using our framework to analyse the power consumption of Android-based G1 and Magic handsets and show that particular choices of message size and send buffer can alter the energy required to send data by an order of magnitude in certain cases.
MULTIFREQUENCY CROSS‐CORRELATION PHASE FLUOROMETRY OF CHLOROPHYLL a FLUORESCENCE IN THYLAKOID AND PSII‐ENRICHED MEMBRANES (1993)

We present here a comparative study on the decay of chlorophyll (Chl) a fluorescence yield in thylakoid membranes and photosystem II (PSII)-enriched samples, measured with multifrequency cross-correlation phase fluorometry. These measurements confirm the general conclusions of Van Mieghem et al. (Biochim. Biophys. Acta 1100, 198-206, 1992), obtained with a flash method, on the effects of reduction of the primary quinone acceptor (QA) on Chl a fluorescence yield of PSII. Different states of the reaction centers of PSII were produced by: (1) pretreatment with sodium dithionite and methyl viologen followed by laser illumination: the doubly reduced QA (QAH2) centers; (2) with laser illumination or pretreatment with diuron: QA- centers; and (3) the addition of micromolar concentration of dichlorobenzoquinone (DCBQ): oxidized QA centers. The data were analyzed with Lorentzian distribution as well as with multiexponential fluorescence decay functions. The analysis with Lorentzian distribution function showed that upon formation of QA-, the major lifetime distribution peak shifted to longer lifetimes: from 0.25 ns to 1.66 ns (pea thylakoid membranes) and from 0.24 ns to 1.31 ns (core PSII). However, when QAH2 was formed, the lifetime distribution peaks shifted back to shorter lifetimes (0.57-0.77 ns) both in thylakoids and PSII membranes. Multiexponential analysis showed three lifetime components: fast (40-400 ps), middle (300-1500 ps) and slow (5-25 ns). When QA- was formed in PSII centers, the amplitude of the fast component decreased, but both the amplitude and the lifetime of the middle component increased severalfold.(ABSTRACT TRUNCATED AT 250 WORDS)
