Tomographic time-frequency analysis and its application toward time-varying filtering and adaptive kernel design for multicomponent linear-FM signals (1994)

Since line integrals through the Wigner spectrum can be calculated by dechirping, calculation of the Wigner spectrum may be viewed as a tomographic reconstruction problem. In the paper, the authors show that all time-frequency transforms of Cohen's class may be achieved by simple changes in backprojection reconstruction filtering. The resolution/cross-term tradeoff that occurs in time-frequency kernel selection is shown to be analogous to the resolution-ringing tradeoff that occurs in computed tomography (CT). "Ideal" reconstruction using a purely differentiating backprojection filter yields the Wigner distribution, whereas low-pass differentiating filters produce cross-term suppressing distributions such as the spectrogram or the Born-Jordan distribution. It is also demonstrated how this analogy can be exploited to "tune" the reconstruction filtering (or time-frequency kernel) to improve the ringing/resolution tradeoff. Some properties of the projection domain, which is also known as the Radon-Wigner transform, are characterized, including the response to signal delays or frequency shifts and projection masking or convolution. Last, time-varying filtering by shift-varying convolution in the Radon-Wigner domain is shown to yield superior results to its analogous Cohen's class adaptive transform (shift-invariant convolution) for the multicomponent, linear-FM signals that are investigated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Put your best face forward (2000)

Highly believable anthropomorphic agents endanger electronic consumers. Because of concerning tendencies in human-agent interaction arising from agents' anthropomorphic qualities, consumers may unwittingly treat agents as competent, trustworthy, living counterparts. This paper concludes that developers must focus agent design on consumer welfare, not technical virtuosity, if legal and ethical perils are to be avoided.
A generic model-based warning system for ground-level ozone monitoring (2005)

The paper describes a model based to develop a highly reliable operational public warning system for air pollution monitoring in Bordeaux, France. The developed methodology is based on hard and soft computing techniques. The proposed method combines new adaptive nonlinear state-space modelling techniques, a gain scheduling strategy and multi-layer perceptron neural networks. The warning system provides additional information regarding the duration of a smog episode that is very important for assessments of human health hazards and negative environmental effects. Experimental results are presented for ground-level ozone concentrations in Bordeaux metropolitan.
Three-component oxysulfenylation reaction: two simple and convenient approaches to β-alkoxy sulfides (2016)

An unprecedented method for the synthesis of β-alkoxy sulfides via a NaI/HBr-mediated three-component oxysulfenylation reaction of alkenes with arylsulfinic acids and alcohols is reported. Furthermore, I2-promoted oxysulfenylation of alkenes using sodium arylsulfinates instead of arylsulfinic acids to synthesise various β-alkoxy sulfides is also described.
Planning and Optimizing Mobile Backhaul for LTE (2015)

Planning the mobile backhaul network for long-term evolution (LTE) is rarely done without considering the available backhaul infrastructure or other radio access technologies. This chapter concentrates on the high-level planning tasks that define the overall guidance, for example, for resiliency planning, quality of service (QoS), dimensioning, routing and subnetting. It presents an introduction to backhaul network deployment scenarios using various technologies, presenting a couple of examples. The chapter describes transport media selection effects on the network topologies and discusses two methods for bandwidth dimensioning and synchronization planning. Transport network needs to support self-organizing networks (SON) auto-connection and automatic neighbor management. The chapter briefly describes the site where eNBs are installed and the relevant backhaul equipment and their functionality at that site. It describes different concepts for performance monitoring and how these can be applied to the mobile network and to backhaul optimization.
Orbital angular momentum generator based on hollow-core photonic bandgap fiber grating (2019)

An orbital angular momentum (OAM) generator was demonstrated by employing a hollow-core photonic bandgap fiber grating. The resulting OAM modes were formed by the strictly degenerate vector modes of and excited by a long-period fiber grating (LPFG). The topological charges of the OAM modes were tuned from −1 to 1 by changing the polarization states of the input fundamental mode. Benefitting from the air-filled core structure, OAM modes generated by an LPFG may be stably transmitted and applied without disturbances resulting from anisotropy of materials.
Impact of intermittent rainwater and wastewater flow on coated and uncoated fractures in chalk (1999)

Two coated and two uncoated slices from the fracture surface of an unsaturated chalk were exposed to short flow events (24, 8, and 9 hours) of industrial wastewater and/or synthetic rainwater, followed by long drying periods (weeks). The topography of the fracture surface was shown to be unstable due to the detachment of colloidal and large‐sized particles during the first 3–7 hours of flow. Following rainwater flow, erosion was more pronounced on the coated than on the uncoated surface (mean erosion of 0.313 and 0.134 mm, respectively). Interaction with industrial wastewater generated a skin of organic matter and gypsum that collapsed following contact with rainwater, leading to a deeper erosion of the uncoated surface (1.238 mm) than of the coated one (0.549 mm). Erosion was measured using a laser‐scanning system and was calculated from high‐resolution topographical maps (elevation z ≤ ± 0.01 mm) generated by Geographic Information System (GIS, ARCInfo) prior to and following the flow experiments. The mean thickness of the erosion was found to be strongly correlated with the thickness of a layer calculated from the total accumulated mass of particles and soluble salts released from the fracture surface. This relationship can be used to evaluate fracture surface erosion in large field and laboratory experiments.
Ultrastructural Immunolocalization of a Major Phosphoprotein in Embryonic Chick Bone (1989)

Immunocytochemistry utilizing the protein A-gold technique was used to examine the ultrastructural cellular and extracellular distribution of a major phosphoprotein in chick bone. HCl-extracts of embryonic and neo-natal chick bones contain a major 66kD phosphoprotein (BPP) which was purified and used to raise polyclonal antibodies in rabbits. The mid-diaphyseal regions of 8-, 12- and 18-day embryonic chick tibiae were fixed with 1% glutaraldehyde and embedded in Epon or Lowicryl. Electron microscopy following incubation of tissue sections with the antibody and the protein A-gold complex revealed specific immunolabeling over the rER and Golgi apparatus of osteoblasts and over those areas of bone matrix containing Ca and P as determined by electron probe x-ray microanalysis. These included extracellular areas in the matrix undergoing early mineralization and electron dense patches occurring at the mineralization front and extending throughout the more mature bone regions. Biochemical analyses of bone tissue processed similarly to that used for immunocytochemistry confirmed the retention of phosphoprotein in the tissue. The spatial correlation of phosphoprotein in the extracellular matrix with Ca-P mineral deposits confirms an earlier report using 33Pi and radioautography and may indicate a role for phosphoproteins in calcification.
Bridged Aromatic Oxo‐ and Thioethers with Intense Emission in Solution and the Solid State (2021)

In this contribution, we report on a class of emitters based on bridged oxo- and/or thioethers revealing striking photoluminescence properties in fluid solution and in the solid state. In total, nine compounds were investigated concerning their photophysical properties, which were interpreted by quantum chemical calculations. To our delight, we discovered compounds possessing nearly identical photoluminescence quantum yields (Φ<sub>F</sub> ) in solution and in the solid state, which has been rarely reported so far. Besides these efforts, we shed light on the influence of polymorphism and solvent polarity on the emission properties. In addition, an in-depth X-ray diffractometric analysis was conducted to correlate molecular packing in the crystal with differences in the photophysical properties.
Abnormal FGFR 3 Expression in Cartilage of Thanatophoric Dysplasia Fetuses (1997)

Thanatophoric dysplasia (TD), the commonest lethal skeletal dysplasia in humans, is accounted for by recurrent mutations in the fibroblast growth factor receptor 3 gene (FGFR 3), causing its constitutive activation in vitro. Taking advantage of medical abortion of 18 TD fetuses, cartilage sections were studied for FGFR 3 gene expression by in situ hybridization and immunohistochemistry. Specific antibodies revealed high amounts of FGFR 3 in cartilage of TD fetuses with no increased level of the corresponding mRNA. The specific signal was mainly detected in the nucleus of proliferative and hypertrophic chondrocytes. Based on this observation and the abnormal expression of collagen type X in hypertrophic TD chondrocytes, we suggest that constitutive activation of the receptor through formation of a stable dimer increases its stability and promotes its translocation into the nucleus, where it might interfere with terminal chondrocyte differentiation.
Outbreaks of nontuberculous mycobacteria (2017)

Mycobacteria outbreaks in healthcare settings have been underrecognized. As we identify additional clusters of infection with better diagnostic tools and heightened awareness, we will likely need better infection control practices to prevent infections in healthcare settings.
Evolution of Cell-Autonomous Effector Mechanisms in Macrophages versus Non-Immune Cells (2016)

Specialized adaptations for killing microbes are synonymous with phagocytic cells including macrophages, monocytes, inflammatory neutrophils, and eosinophils. Recent genome sequencing of extant species, however, reveals that analogous antimicrobial machineries exist in certain non-immune cells and also within species that ostensibly lack a well-defined immune system. Here we probe the evolutionary record for clues about the ancient and diverse phylogenetic origins of macrophage killing mechanisms and how some of their properties are shared with cells outside the traditional bounds of immunity in higher vertebrates such as mammals.
[Basic studies on chronic polyarthritis as a collagen-autoimmune disease]. (1978)

Clinical and experimental data establishing a hypothesis about rheumatoid arthritis (RA) as a collagen auto-immune disease are reviewed, beginning with the demonstration of rheumatoid synovial collagenase, the demonstration of collagen antibodies in the serum and the synovial fluid of patients with RA, the demonstration of collagen inclusion bodies and collagen-anticollagen immune complexes in synovial fluid cells and the synovial fluid of patients with RA, and leading to the in vitro demonstration of the inflammatory effect of such complexes, and the induction of experimental arthritis by these complexes. Each section contains tabular summaries of various investigations. Finally, a relation between these observations and the conclusions deduced from them and the appearance of rheumatoid factors in RA and the pathogenic effect of rheumatoid factor - gammaglobulin aggregates is considered.
Pacific Northwest Laboratory`s Lighting Technology Screening Matrix (1994)

Pacific Northwest Laboratory has developed the Lighting Technology Screening Matrix (LTSM), a software tool to evaluate alternative lighting retrofit technologies according to life-cycle cost. The LTSM can be used to evaluate retrofits for most configurations of fluorescent, incandescent, high- and low-pressure sodium, metal halide, mercury vapor, and exit lighting systems for any level of operation, electricity price, discount rate, and utility rebate. This tool was developed, in support of the Federal Relighting Initiative as part of the Department of Energy`s Office of Federal Energy Management Program (DOE/FEMP) to assist federal government facilities in their efforts to comply with the 10 CFR 436 mandated life-cycle costing for energy equipment investments. The LTSM has been used in the course of seven site modernization projects. These projects consisted of determining the cost-effective, energy-efficiency potential at military installations. Each project treated the entire military installation as an integrated system, proposed a large number of potential efficiency projects affecting all end-uses and fuel types, and analyzed the cost-effectiveness of each project. The LTSM was used for the lighting portion of these projects. Lighting was, overall, one of the major areas of potential efficiency improvements, accounting for over 30% of the cost-effective resource. Altogether over $43 million worth of cost-effective efficiency investments were identified, worth an estimated $6 million annually in energy, demand, and operations and maintenance (O&M) savings. This paper describes the LTSM and demonstrates its application in a case study at one of the federal installations analyzed.

Robust Maximum Association Between Data Sets: The R Package ccaPP (2016)

An intuitive measure of association between two multivariate data sets can be defined as the maximal value that a bivariate association measure between any one-dimensional projections of each data set can attain. Rank correlation measures thereby have the advantage that they combine good robustness properties with good efficiency. The software package ccaPP provides fast implementations of such maximum association measures for the statistical computing environment R. We demonstrate how to use package ccaPP to compute the maximum association measures, as well as how to assess their significance via permutation tests.
Continuous glucose monitoring in neonates: a review (2017)

Continuous glucose monitoring (CGM) is well established in the management of diabetes mellitus, but its role in neonatal glycaemic control is less clear. CGM has provided important insights about neonatal glucose metabolism, and there is increasing interest in its clinical use, particularly in preterm neonates and in those in whom glucose control is difficult. Neonatal glucose instability, including hypoglycaemia and hyperglycaemia, has been associated with poorer neurodevelopment, and CGM offers the possibility of adjusting treatment in real time to account for individual metabolic requirements while reducing the number of blood tests required, potentially improving long-term outcomes. However, current devices are optimised for use at relatively high glucose concentrations, and several technical issues need to be resolved before real-time CGM can be recommended for routine neonatal care. These include: 1) limited point accuracy, especially at low or rapidly changing glucose concentrations; 2) calibration methods that are designed for higher glucose concentrations of children and adults, and not for neonates; 3) sensor drift, which is under-recognised; and 4) the need for dynamic and integrated metrics that can be related to long-term neurodevelopmental outcomes. CGM remains an important tool for retrospective investigation of neonatal glycaemia and the effect of different treatments on glucose metabolism. However, at present CGM should be limited to research studies, and should only be introduced into routine clinical care once benefit is demonstrated in randomised trials.
Role of the Rhesus glycoprotein, Rh B glycoprotein, in renal ammonia excretion (2010)

Rh B glycoprotein (Rhbg) is a member of the Rh glycoprotein family of ammonia transporters. In the current study, we examine Rhbg's role in basal and acidosis-stimulated acid-base homeostasis. Metabolic acidosis induced by HCl administration increased Rhbg expression in both the cortex and outer medulla. To test the functional significance of increased Rhbg expression, we used a Cre-loxP approach to generate mice with intercalated cell-specific Rhbg knockout (IC-Rhbg-KO). On normal diet, intercalated cell-specific Rhbg deletion did not alter urine ammonia excretion, pH, or titratable acid excretion significantly, but it did decrease glutamine synthetase expression in the outer medulla significantly. After metabolic acidosis was induced, urinary ammonia excretion was significantly less in IC-Rhbg-KO than in control (C) mice on days 2-4 of acid loading, but not on day 5. Urine pH and titratable acid excretion and dietary acid intake did not differ significantly between acid-loaded IC-Rhcg-KO and C mice. In IC-Rhbg-KO mice, acid loading increased connecting segment (CNT) cell and outer medullary collecting duct principal cell Rhbg expression. In both C and IC-Rhbg-KO mice, acid loading decreased glutamine synthetase in both the cortex and outer medulla; the decrease on day 3 was similar in IC-Rhbg-KO and C mice, but on day 5 it was significantly greater in IC-Rhbg-KO than in C mice. We conclude 1) intercalated cell Rhbg contributes to acidosis-stimulated renal ammonia excretion, 2) Rhbg in CNT and principal cells may contribute to renal ammonia excretion, and 3) decreased glutamine synthetase expression may enable normal rates of ammonia excretion under both basal conditions and on day 5 of acid loading in IC-Rhbg-KO mice.
Which PKI (public key infrastructure) is the right one? (panel session) (2000)

Several organizations are setting up Public Key Infrastructures, examples are: the Corporation for Research and Educational Networking (CREN), the Federal Government plans to fund 7 Public Key Infrastructure Models pilot programs at different federal agencies. However, experts have quite different viewpoints on how to set up
Damping Evaluation of Linseed Oil-Based Engineering Elastomers by Vibration Response Method (2014)

A low cost experimental setup has been fabricated for evaluation of vibration damping properties of a variety of elastomers developed from linseed oil. Free and forced vibration principles were utilized in this experimental setup. Under forced vibration, the shear loss factor varies from 0.37 to 1.03 at 2nd bending vibration mode and 0.43 to 0.99 at 3rd bending vibration mode for different elastomers. The loss factor varies from 0.52 to 0.94 under free vibration. The loss factors determined by both forced and free vibration techniques are in good agreement with the loss factors obtained from dynamic mechanical analysis. The ultimate tensile strength and Young’s modulus of the elastomers vary from 0.37 to 3.71 MPa and 0.27 to 10.27 MPa, respectively, whereas these properties in compression are in the range of 3.1 to 72.9 MPa and 1.5 to 30.1 MPa, respectively. Thus, these elastomers are mechanically stable for vibration damping applications.
Preemptive Hadoop Jobs Scheduling under a Deadline (2012)

MapReduce has become the dominant programming model in a cloud-based data processing environment, such as Hadoop. First In First Out (FIFO) is the default job scheduling policy of Hadoop, but it cannot guarantee that the job will be completed by a specific deadline. Research has been focused on developing deadline-based MapReduce schedulers by using the non-preemptive scheduling approach. However, compared with the non-preemptive scheduling approach, the preemptive scheduling approach has some advantages, such as the total completion time and slot utilization. In this paper, we first formulated the preemptive scheduling problem under deadline constraint, and then we proposed preemptive scheduling algorithms. To our knowledge we implemented the first real preemptive job scheduler to meet deadlines on Hadoop. The experimental results indicate that the preemptive scheduling approach is promising, which is more efficient than the non-preemptive one for executing jobs under a certain deadline.
Effect of Mixing Condition of Elemental Powders on Synthesis of TiC Phase and Consolidation by Pressure Sintering Method (2019)

The attempt of fabrication of TiC bulk material from elemental Ti and C powder was studied. The effect of mixing method and consolidation temperature on the densification behavior and microstructural properties of the compact were studied. The elemental Ti and C powder were mixed by two different methods, rotating stainless vessel with shaking motion (we call regular mixing in this paper) and ball milling apparatus (MA). The formation of TiC from regular mixed powder was occurred gradually with increasing temperature below 1373 K. On the other hand, MA powder ball milled for 1800 ks was started to form TiC phase at around 750 K. Therefore, only regular mixed powder is able to deform and sinter below 1373 K by pressure sintering due to the existence of metallic Ti phase. At high temperature of 1773 K, MA powder having fine microstructure achieved higher density than regular mixed powder with coarse microstructure.
High Capacity Converged Passive Optical Network and RoF-Based 5G+ Fronthaul Using 4-PAM and NOMA-CAP Signals (2020)

Network architectural changes to satisfy all the 5G+ mobile network specifications and requirements are necessary due to the popularization of streaming and cloud applications on omnipresent portable devices. The combination of massive installation of micro-cell antenna sites with the cloud access radio network (C-RAN) architecture has recently been nominated as a promising technology for high-capacity mobile fronthaul links, albeit at a high cost. An alternative approach for next-generation fronthaul networks is to utilize the already deployed passive optical networks (PONs) where wireless and wired services may coexist in a converged manner. Non-orthogonal multiple access (NOMA) modulation with multi-band carrierless amplitude and phase modulation (NOMA-CAP) has recently been investigated as a promising 5G+ modulation format candidate to increase the capacity and flexibility of future mobile networks. Here, we experimentally demonstrate the convergence of a NOMA-CAP wireless waveform with a single-carrier wired signal in a PON scenario using radio-over-fiber (RoF) technology. Specifically, fifteen NOMA-CAP bands, with two NOMA power levels to double the capacity, transmit 15 Gb/s multiplexed with a digital 10 Gb/s four-level pulse amplitude modulation (PAM-4) signal for downlink application. Two converged system implementations have been considered, first using electrical frequency division multiplexing (EFDM) and secondly using the hybrid EFDM-wavelength division multiplexing (EFDM-WDM). Successful transmission through a 25 km span of standard single-mode fiber is achieved with negligible transmission penalty for both proposed converged solutions.
