Dependence of DOP-based DGD monitors on the optical power spectrum of equal-pulse-width data formats (2004)

We demonstrate that the DGD monitoring range and sensitivity of PMD monitors is optical-spectrum-dependent in 10-and-40-Gbit/s CSRZ, ACRZ and RZ signals even when the pulse-widths are identical, and introduce a method to monitor PMD in CSRZ and ACRZ systems.
Study on reduction in electric field, charged voltage, ion current and ion density under HVDC transmission lines by parallel shield wires (1989)

Several models of shield wire were tested with the Shiobara HVDC (high-voltage direct current) test line. The models contain typical standard wires that are generally used to reduce field effects at ground level, neutral conductors placed at lower parts of the DC line, and an earth corona model to intentionally cancel positive or negative ions by generating ions having opposite polarity to ions flowing into the wire. The authors describe experimental results on the effects of these shield wires and a method to predict shielding effects. It is concluded that shielding using the earth corona is quite an effective method; it is even applicable to the reduction of ion density, which has normally been considered difficult.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Effect of pentoxifylline on regimen related toxicity in patients undergoing allogeneic or autologous bone marrow transplantation. (1994)

An unblinded, historical controlled study of 49 bone marrow transplant (BMT) patients was carried out in our institution to assess the effect of oral pentoxifylline (PTX) on BMT regimen related toxicity (RRT). Twenty-eight consecutively treated BMT patients (17 allogeneic, 11 autologous) were entered into the PTX treatment group and treated with oral PTX 400 mg at intervals of 4 h from day -10 until day +35 or discharge, whichever came sooner. These were compared with a control group of 21 BMT patients (14 allogeneic, 7 autologous). Patient groups were very similar with respect to age, sex, conditioning regimen, graft-versus-host disease (GVHD) prophylaxis and baseline liver and renal function. Compliance with the drug was 85%. Despite this, no significant difference in days of mucositis or hyperalimentation, incidence or severity of renal or hepatic dysfunction, hypertension, GVHD, weight gain > 5%, day 100 mortality or length of hospitalization was observed. Median follow-up is > 2 years in both groups and no difference in relapse or survival was observed. We were unable to confirm an effect of oral PTX on BMT related morbidity or mortality.
Novel TARDBP Sequence Variant and C9ORF72 Repeat Expansion in a Family With Frontotemporal Dementia (2012)

Frontotemporal lobar degeneration (FTLD) is a genetically heterogenous syndrome and has been associated most recently with a hexanucleotide repeat expansion within the C9ORF72 gene. Pathogenic TDP-43 gene (TARDBP) mutations have been identified in amyotrophic lateral sclerosis, but the role of TARDBP mutations in FTLD is more contradictory. To investigate the role of TARDBP mutations in a clinical series of Finnish FTLD patients, we sequenced TARDBP exons 1 to 6 in 77 FTLD patients. No evident pathogenic mutations were found. We identified a novel heterozygous c.876_878delCAG sequence variant in 2 related patients with behavioral variant frontotemporal dementia without amyotrophic lateral sclerosis. The variant is predicted to cause an amino acid deletion of serine at position 292 (p.Ser292del). However, p.Ser292del was also found in 1 healthy middle-aged control. Interestingly, both patients carried the C9ORF72 expansion. Therefore, the TARDBP variant p.Ser292del might be considered a rare polymorphism and the C9ORF72 repeat expansion the actual disease-causing mutation in the family. Our results suggest that TARDBP mutations are a rare cause of FTLD. However, the interaction of several genetic factors needs to be taken into account when investigating neurodegenerative diseases.

Background, Motivation, and Overview (2016)

This chapter discusses many important aspects of vibration. It presents a primer on high-cycle fatigue (HCF) to illustrate the practical importance of studying vibrations. Systems vibrate due to the interplay (energy exchange) between stiffness (restoring), inertia (mass), and damping (drag) related forces. The equations of motion for a vibrating system model provide a starting point for simulating the system's response to initial conditions, external forces, or parametric excitation (time-dependent system parameters). The chapter discusses approaches for deriving the equations of motion for a model of a vibrating system. The Lagrange-Hamilton approach utilizes expressions for kinetic and potential energy to develop the equations of motion for the system. The finite element method (FEM) is widely used in industry for avoiding machinery and structural vibration problems. Active vibration control (AVC) devices can replicate the behavior of a passive device and produce forces with a more general dependence on motion variables.
MR signal conditioning for an electro-optic conversion with a polarization state modulator (2023)

The coaxial cables connecting coils to the MRI are subject to many unwanted interactions with RF pulses and with patients&amp;rsquo; tissues. Currents flowing on the shielding of the cable can lead to local SAR increase and RF-induced burns. Despite their limitations and the amount of effort to discard them, there is still no satisfying alternative. One of the issue for competing technologies is to safely provide on coil power supply without cables inside the MRI. In this work, we propose to evaluate the feasibility of passive optical conversion and transmission of the signal to the MRI console.
Nonlocal van der Waals density functional: The simpler the better (2010)

We devise a nonlocal correlation energy functional that describes the entire range of dispersion interactions in a seamless fashion using only the electron density as input. The new functional is considerably simpler than its predecessors of a similar type. The functional has a tractable and robust analytic form that lends itself to efficient self-consistent implementation. When paired with an appropriate exchange functional, our nonlocal correlation model yields accurate interaction energies of weakly-bound complexes, not only near the energy minima but also far from equilibrium. Our model exhibits an outstanding precision at predicting equilibrium intermonomer separations in van der Waals complexes. It also gives accurate covalent bond lengths and atomization energies. Hence the functional proposed in this work is a computationally inexpensive electronic structure tool of broad applicability.

Improved lithium–sulfur cells with a treated carbon paper interlayer (2012)

A simple, low-cost modification of lithium-sulfur (Li-S) cells by placing a treated carbon paper between the sulfur electrode and the separator has been investigated to significantly improve the performance of Li-S cells. The treated carbon paper was prepared by an alcohol-alkaline/thermal treatment of a commercial Toray carbon paper, introducing hydroxyl functional groups and micro-cracks on the carbon fibers in the carbon paper, which enhances the hydrophilicity and increases surface areas of the carbon paper matrix. The modified Li-S cells deliver a higher initial capacity of 1651 mAh g(-1) at 1.5-2.8 V at a rate of C/5 compared to the cells without any interlayer or with an untreated carbon paper interlayer. The cells with the treated carbon paper offer additional improvement in performance when the discharge cut-off voltage is raised to 1.8 V: 1057, 1002, and 929 mAh g(-1) after 100 cycles, respectively, at C/5, C/2, and 1 C rates. The improved cell performance is attributed to the 3D architecture of the carbon paper interlayer, serving as a conductive skeleton for trapping and depositing dissolved sulfur-containing active materials, as confirmed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The novel configuration presented here offers a low-cost approach to overcome the persistent problems of Li-S cells.
Beyond Heart Rate Variability (2006)

The autonomic nervous system (ANS) plays a role in a wide range of somatic and mental diseases. Whereas the role of the ANS in the regulation of the cardiovascular system seems evident, its role in the regulation of other systems associated with allostasis is less clear. Using a model of neurovisceral integration we describe how the ANS and parasympathetic tone in particular may be associated with the regulation of allostatic systems associated with glucose regulation, hypothalamic-pituitary-adrenal (HPA) axis function, and inflammatory processes. Decreased vagal function and heart rate variability (HRV) were shown to be associated with increased fasting glucose and hemoglobin A1c levels, increased overnight urinary cortisol, and increased proinflammatory cytokines and acute-phase proteins. All of these factors have been associated with increased allostatic load and poor health. Thus, vagal activity appears to play an inhibitory function in the regulation of allostatic systems. The prefrontal cortex and the amygdala are important central nervous system structures linked to the regulation of these allostatic systems via the vagus nerve. Finally, the identification of this neurovisceral regulatory system may help to illuminate the pathway via which psychosocial factors may influence health and disease.

Optimizing test strategies for SONET/SDH/ATM network element manufacturing (2002)

Time-to-market pressures dictate short test system development times for manufacturers of SONET, SDH and ATM equipment. This paper will evaluate the test process as part of the manufacturing process, and offer methodologies to optimize cost, throughput and product quality. This can be achieved by adopting the optimal test strategy and employing the right T&M instrumentation solutions.
Direct Observation of Defect Levels in InN by Soft X-ray Absorption Spectroscopy (2006)

We have used synchrotron-based near-edge X-ray absorption fine structure (NEXAFS) spectroscopy to study the electronic structure of nitrogen-related defects in InN(0001). Several defect levels within the band gap or the conduction band of InN were clearly resolved in NEXAFS spectra around the nitrogen K-edge. We attribute the level observed at 0.3 eV below the conduction band minimum (CBM) to interstitial nitrogen, the level at 1.7 eV above the CBM to antisite nitrogen, and a sharp resonance at 3.2 eV above the CBM to molecular nitrogen, in full agreement with theoretical simulations.

Development of the technology for ‘Diprifusor’ TCI systems (1998)

The availability of fast-acting intravenous drugs for anaesthesia has encouraged anaesthetists to gain a practical understanding of the pharmacodynamics and pharmacokinetics of these drugs to optimise their administration. 'Diprifusor' technology uses pharmacokinetic modelling to control the infusion rate of a pump, providing the anaesthetist with direct control of the blood concentration rather than indirect control by the infusion rate. The 'Diprifusor' electronics module is a dual microprocessor component that can be incorporated into an infusion pump to provide this mode of administration. This paper describes the module's infusion control system, prefilled syringe recognition system and the safety aspects addressed by the design.
Measuring Gene Expression (2008)

Measuring Gene Expression is an all-in-one introduction to the main methods of measuring gene expression, including RT-PCR, differential display, RNA interference, reporter genes, microarrays, and proteomics, as well as&nbsp;a section on RNA isolation and analysis. There&nbsp;is an overview of each method: its pros and cons, sample preparation, sources of error, and data interpretation.
Line Failure Localization of Power Networks Part I: Non-Cut Outages (2021)

Transmission line failures in power systems propagate non-locally, making the control of the resulting outages extremely difficult. In this work, we establish a mathematical theory that characterizes the patterns of line failure propagation and localization in terms of network graph structure. It provides a novel perspective on distribution factors that precisely captures Kirchhoff's Law in terms of topological structures. Our results show that the distribution of specific collections of subtrees of the transmission network plays a critical role on the patterns of power redistribution, and motivates the block decomposition of the transmission network as a structure to understand long-distance propagation of disturbances. In Part I of this paper, we present the case when the post-contingency network remains connected after an initial set of lines are disconnected simultaneously. In Part II, we present the case when an outage separates the network into multiple islands.
Support For Conservation Policies And Values For Conservation: Are They Related? (2010)

E conomists frequently assess stated preferences for land use outcomes as ei-ther independent of information regarding policy implementation mechanisms or a function of a vaguely speciﬁed management process. The rural public, however, not only may be concerned with the consequences of land management, but also may have systematic preferences for policy procedures applied to management goals. There is no guarantee that residents of rural or urban-fringe communities will support policies that are consistent with their preferences for land use outcomes. To the contrary, they may have preferences for certain outcomes, such as conservation of wildlife habitat, public access, or open space, but be unwilling to accept the management processes necessary for those outcomes (Philo and Johnston 2004).
Numerical investigation of non-axisymmetric end wall contouring effects in a low-speed compressor tandem stator (2021)

The present paper reports about a numerical investigation on the effects of non-axisymmetric endwall contouring on a low-speed compressor tandem stator. Usually related to a stochastic or meta-heuristic optimization approach, this technique reserves still several unknowns regarding its global applicability and general effectiveness, in particular concerning its application to compressor stages. The scope of this paper is to provide clarity over fundamental effects of non-axisymmetric endwall contouring on tandem configurations, in order derive some fundamental guidelines to be used in future contouring definition and tandem stator aerodynamic design. The reference geometry used in this research is a standard tandem vane arrangement with smooth endwall and designed to represent a datum stage configuration for future investigations of such blade geometries, experimental work on a low-speed research compressor being a next step.This paper reports about a thorough flow field analysis of the optimized geometry in order to understand local mechanisms occurring with non-axisymmetric contouring in the tandem stator passage flow field and its overall performance. An improvement of 0.7% polytropic stage efficiency was identified at near stall condition. Furthermore, characteristics of reference and contoured geometry are compared at design and off-design conditions. One key interaction of the endwall contouring with the tandem stator passage flow field has been identified as origin of major flow field improvement at hub and shroud: the reduction of the cross-passage flow, which results in reduction of the strength of the passage vortex and of the hub corner separation on both blades. The paper concludes with some guidelines to derive on how endwall contouring can be most effectively applied in tandem vanes of low-speed compressor stages.

Genome-wide quantification of homeolog expression ratio revealed nonstochastic gene regulation in synthetic allopolyploid Arabidopsis (2014)

Genome duplication with hybridization, or allopolyploidization, occurs commonly in plants, and is considered to be a strong force for generating new species. However, genome-wide quantification of homeolog expression ratios was technically hindered because of the high homology between homeologous gene pairs. To quantify the homeolog expression ratio using RNA-seq obtained from polyploids, a new method named HomeoRoq was developed, in which the genomic origin of sequencing reads was estimated using mismatches between the read and each parental genome. To verify this method, we first assembled the two diploid parental genomes of Arabidopsis halleri subsp. gemmifera and Arabidopsis lyrata subsp. petraea (Arabidopsis petraea subsp. umbrosa), then generated a synthetic allotetraploid, mimicking the natural allopolyploid Arabidopsis kamchatica. The quantified ratios corresponded well to those obtained by Pyrosequencing. We found that the ratios of homeologs before and after cold stress treatment were highly correlated (r = 0.870). This highlights the presence of nonstochastic polyploid gene regulation despite previous research identifying stochastic variation in expression. Moreover, our new statistical test incorporating overdispersion identified 226 homeologs (1.11% of 20 369 expressed homeologs) with significant ratio changes, many of which were related to stress responses. HomeoRoq would contribute to the study of the genes responsible for polyploid-specific environmental responses.
Electrochemical Detection of MicroRNAs via Gap Hybridization Assay (2010)

MicroRNAs have recently been associated with cancer development by acting as tumor suppressors or oncogenes and could therefore be applied as molecular markers for early diagnosis of cancer. In this work, we established a rapid, selective, and sensitive gap hybridization assay for detection of mature microRNAs based on four components DNA/RNA hybridization and electrochemical detection using esterase 2-oligodeoxynucleotide conjugates. Complementary binding of microRNA to a gap built of capture and detector oligodeoxynucleotide, the reporter enzyme is brought to the vicinity of the electrode and produces enzymatically an electrochemical signal. In the absence of microRNA, the gap between capture and detector oligodeoxynucleotide is not filled, and missing base stacking energy destabilizes the hybridization complex. The gap hybridization assay demonstrates selective detection of miR-16 within a mixture of other miRNAs, including the feasibility of single mismatch discrimination. Applying the biosensor assay, a detection limit of 2 pM or 2 amol of miR-16 was obtained. Using isolated total RNA from human breast adenocarcinoma MCF-7 cells, the assay detected specifically miR-21 and miR-16 in parallel, and higher expression of oncogene miR-21 compared to miR-16 was demonstrated. Including RNA isolation, the gap hybridization assay was developed with a total assay time of 60 min and without the need for reverse transcription PCR amplification of the sample. The characteristics of the assay developed in this work could satisfy the need for rapid and easy methods for early cancer marker detection in clinical diagnostics.
Optimal Fan Speed Control for Thermal Management of Servers (2009)

Improving the cooling efficiency of servers has become an essential requirement in data centers today as the power used to cool the servers has become an increasingly large component of the total power consumption. Additionally, fan speed control has emerged in recent years as a critical part of system thermal architecture. However, the state of the art in server fan control often results in over provisioning of air flow that leads to high fan power consumption. It can be exacerbated in server architectures that share cooling resources among server components, where single hot spot can often drive the operation of a multiplicity of fans. To address this problem, this paper presents a novel multi-input multi-output (MIMO) fan controller that utilizes thermal models developed from first-principles to manipulate the operation of fans. The controller tunes the speeds of individual fans proactively based on prediction of the sever temperatures. Experimental results show that, with fans controlled by the optimal controller, over-provisioning of cooling air is eliminated, temperatures are more tightly controlled and fan energy consumption is reduced by up to 20% compared to that with a zone-based feedback controller.
Phonon spectrum of a model of electronically excited silicon (1982)

With a view to clarifying the process proposed in the plasma-annealing hypothesis for laser-induced recrystallization, we have performed a simple calculation of phonon frequencies in electronically excited silicon. We make assumptions most favorable to the plasma-annealing hypothesis, i.e., we assume that the laser energy remains in the electronic system. We use a one-parameter interpolation of the electronic dielectric constant between the bond charge and the free-electron models in a computation of the phonon spectrum. The calculation yields a softening of the [111] zone-boundary transverse-acoustic phonons. Typically, such a softening would be thought to lead to a structural phase transition. The excited electron densities needed for this softening are in the range (6-10)\ifmmode\times\else\texttimes\fi{}${10}^{21}$ ${\mathrm{cm}}^{\ensuremath{-}3}$ which seems unreasonably large to us. Thus, on two counts, we have grounds for rejecting the plasma-annealing hypothesis.
