Morphological and functional changes in the dialysed peritoneal cavity: impact of more biocompatible solutions (2002)

Loss of peritoneal function is a major factor leading to treatment failure in peritoneal dialysis (PD). To date, however, the relationship between the observed functional changes (reduction in ultrafiltration and changes in solute transport) and the structural alterations in the membrane have not been fully defined. Here we present data from the Peritoneal Biopsy Registry identifying and characterizing both changes in parietal peritoneal membrane thickness (degree of fibrosis) and vascular alterations (blood vessel degenerative changes) and relate these to the duration of dialysis. The genesis of functional changes in the membrane may be related to these vascular alterations. This issue is discussed in relation to the importance of nitric oxide and its synthetic enzymes in this process and its potential interaction with endothelial cell aquaporin function. It is widely believed that conventional acidic, lactate-buffered glucose-containing dialysis solutions contribute to both the structural and functional changes in the dialysed peritoneal membrane. The introduction of new more biocompatible solutions potentially allows us to reverse or attenuate these negative changes. This will be discussed in the context of our current understanding of peritoneal pathology in PD.
Adenovirus E4 Gene Promotes Selective Endothelial Cell Survival and Angiogenesis via Activation of the Vascular Endothelial-Cadherin/Akt Signaling Pathway (2004)

The early 4 region (E4) of the adenoviral vectors (AdE4(+)) prolongs human endothelial cell (EC) survival and alters the angiogenic response, although the mechanisms for the EC-specific, AdE4(+)-mediated effects remain unknown. We hypothesized that AdE4(+) modulates EC survival through activation of the vascular endothelial (VE)-cadherin/Akt pathway. Here, we showed that AdE4(+), but not AdE4(-) vectors, selectively stimulated phosphorylation of both Akt at Ser(473) and Src kinase in ECs. The phosphatidylinositol 3-kinase (PI3K) inhibitors LY294002 and wortmannin abrogated AdE4(+) induction of both phospho-Akt expression and prolonged EC survival. Regulation of phospho-Akt was found to be under the control of various factors, namely VE-cadherin activation, Src kinase, tyrosine kinase, extracellular signal-regulated kinase (ERK), and c-Jun N-terminal kinase (JNK). Downstream targets of Akt signaling resulted in glycogen synthase kinase-3alpha/beta phosphorylation, beta-catenin up-regulation, and caspase-3 suppression, all of which led to AdE4(+)-mediated EC survival. Furthermore, infection with AdE4(+) vectors increased the angiogenic potential of ECs by promoting EC migration and capillary tube formation in Matrigel plugs. This selective AdE4(+)-mediated enhanced motility of ECs was also blocked by PI3K inhibitors. Taken together, these results suggest that activation of the VE-cadherin/Akt pathway is critical for AdE4(+)-mediated survival of ECs and angiogenic potential.
Camera Models and Fundamental Concepts Used in Geometric Computer Vision (2010)

Camera Models and Fundamental Concepts Used in Geometric Computer Vision is mainly motivated by the increased availability and use of panoramic image acquisition devices, in computer vision and several of its applications. Different technologies and different computational models thereof exist and algorithms and theoretical studies for geometric computer vision ("structure-from-motion") are often re-developed without highlighting common underlying principles. Camera Models and Fundamental Concepts Used in Geometric Computer Vision surveys the image acquisition methods used in computer vision and especially, the vast number of camera models that have been proposed and investigated over the years, and points out similarities between different models. Results on epipolar and multi-view geometry for different camera models are reviewed as well as various calibration and self-calibration approaches, with an emphasis on non-perspective cameras. Camera Models and Fundamental Concepts Used in Geometric Computer Vision also describes what the authors consider are fundamental building blocks for geometric computer vision or structure-from-motion: epipolar geometry, pose and motion estimation, 3D scene modeling, and bundle adjustment. The main goal here is to highlight the core principles of these, which are independent of specific camera models.
Cellular Transplantation and Spinal Cord Injury (2000)

Spinal cord injury is often characterized by immediate and irreversible loss of sensory and motor functions below the level of injury. Cellular transplantation in various experimental models of spinal cord injury has been used as a strategy for reducing deficits and improving functional recovery. The general strategy has been aimed at promoting regeneration of intrinsic injured axons with the development of alternative pathways that facilitate a partial functional connection. Other objectives of cellular transplantation studies have included replacement of lost cellular elements, alleviation of chronic pain, and modulation of the inflammatory response after injury. This review focuses on the cell types that have been used in spinal cord transplantation studies in the context of evolving biological perspectives, technological advances, and new therapeutic strategies and serves as a point of reference for future studies.
Wearable Activity Tracking in Car Manufacturing (2008)

In an industrial scenario, a context-aware wearable computing system could support a production or maintenance worker. The system could recognize the worker's actions and deliver just-in-time information about activities the worker is to perform. This article reports on an ongoing effort to develop and test such real-life industrial activity-tracking systems within the European Union wearIT@work project. Two case studies conducted in cooperation with the European car manufacturer Skoda demonstrate how the system supports the training of assembly workers and quality assurance in the assembly line. The lessons learned from these studies are applicable in other areas. This article is part of a special issue on activity-based computing.
Process analytical technology for monitoring pharmaceuticals freeze-drying – A comprehensive review (2018)

The goal of this paper is to review the available process analytical technology tools for monitoring the batch freeze-drying process for pharmaceuticals. These systems aim evaluating in-line product temperature, sublimation flow rate, and values of some model parameters in such a way that it can be used for in-line or off-line process optimization. A detailed survey of the systems proposed in the literature is presented, grouping them on the basis of monitored variable, namely, product temperature, heat flux to the product, sublimation flux, and, finally, other variables. The advantages and drawbacks of the techniques are critically assessed, taking into account the possibility of using them not only at lab-scale but also at production scale, beside, obviously, the possibility of getting reliable measurements of the desired variables.
Interfacing a radiology information system and a picture archiving and communication system (2002)

In some medical imaging (MI) departments two information systems have developed in parallel, a radiology information management system (RIMS) and a picture archiving and communication system (PACS). A connection between the two applications is required to adequately support the medical imaging process and is vital to a completely digital MI department. The RIMS-PACS interface will provide the mechanism for single-point access to all of the information required by a radiologist for a diagnosis. The authors describe the results of the analysis of the two systems and outline possibilities for their interconnection. The high-level design of the RIMS-PACS interface as reported will satisfy the clinical users' need for single-point access to the data required for clinical radiology. It overcomes the obstacles presented by the low connectivity of the two applications. The complexity of the analysis required to design the interface highlights the need for more strategic planning before information systems are implemented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
JTAG system test in a MicroTCA world (2007)

The telecommunications industry has developed new system architectures through the PCI Industrial Computer Manufacturers Group (PICMG) organization. These are the Advanced Telecom Computing Architecture (ATCA) platforms that consist of the ATCA, ATCA300, Advanced Mezzanine Card (AMC), and MicroTCA specifications. Unfortunately, only the AMC and MicroTCA specification directly addresses testability using an IEEE Std 1149.1 (JTAG) compatible interface. This paper will address the system test facility specified in the MicroTCA specification for testing the incorporated AMC modules as well as the MicroTCA Carrier Hub (MCH) controllers. Access to the individual AMC JTAG chains is provided using a JTAG Switch Module that provides a programmable star architecture in the system.
Optical properties of waveguide-coupled nanowires for sub-wavelength detection in microspectrometer applications (2015)

In this paper we experimentally investigate optical interactions between gold nanowires and fs-laser written waveguides in a view of applications for stationary-wave integrated Fourier-transform spectrometers in a movable mirror configuration. For this purpose we fabricated gold nanowires of widths in the range from 40 to 130 nm and of 25 nm in thickness directly on the surface of a borosilicate glass containing fs-laser written optical waveguides beneath. The out-coupling efficiency and the radiation pattern angular distribution were investigated at the wavelength of 850 nm, dependent on the geometrical size of the nanowires, the position of the waveguides under the surface, and the light polarization. We also report measured plasmonic scattering spectra of the nanowires in the wavelength range of 400 to 900 nm. Our findings show that the chosen geometries and material systems are promising candidates for the use in integrated focal plane array spectrometer devices. Finally, we demonstrate the successful operation of a waveguide spectrometer modified by a movable mirror with a stroke of more than 10 <I>μ</I>m.
Statistical simulation of high-speed links with transmitter and receiver nonlinearities (2014)

In this paper, we present a statistical simulation approach to evaluate the performance of high-speed links with transmitter and receiver nonlinearities. The linear time-invariant assumption in conventional fast simulation techniques is not anymore valid. The transmitters and receivers of current and next generation high-speed links are more complex and nonlinear in order to improve power and area efficiency, minimize parasitic, transmit larger swing and mitigate higher attenuation. Therefore, the calculation of bit error rate using probability density functions of the signal and impairments based on linear analysis can give inaccurate results. Instead, we use Hammerstein and Wiener models to modify the probability distribution to account for the transmitter and receiver nonlinearities. We demonstrate the approach with examples of high-speed links with NRZ and PAM4 signaling.
Nonlinear source resistance in high-voltage microwave AlGaN/GaN HFETs (2006)

Wide bandgap semiconductors are used to fabricate field-effect transistors with significantly improved RF output power compared to GaAs- and InP-based devices. Nitride-based heterostructure field-effect transistors can be biased at high drain voltages, up to and exceeding 100 V, which results in high RF output power. However, the operation of these devices at high drain bias introduces physical phenomena within the device that affect both dc and RF performance. In this study, the existence of a nonlinear source resistance due to space-charge limited current conditions is demonstrated and verified. Inclusion of the nonlinear source resistance in a physics-based device simulator produces excellent agreement between simulated and measured data. The nonlinear source resistance degrades RF performance and limits amplifier linearity.
Introduction: Culture and politics in Palestine/Israel (2021)

For many years, the study of power struggles in Palestine/Israel tended to identify “power” with the state, military, and the economy (Stein and Swedenburg 2005). The “cultural turn” in the social sciences and the humanities since the 1970s was slow to gain ground in the Palestinian–Israeli context. For example, a Google Scholar search of materials that include the words “military” and “Palestine” in their title reveals that 54 per cent of these materials were published after 2000. However, the share of materials published after 2000 among items that include the words “Palestine” and “music” in their title is 70 per cent, of “Palestine” and “cinema”/“movies”/“ﬁlms” is 73 per cent, while for “Palestine” and “sport(s)” or “theater” the share of the past two decades is 100 per cent. While the semiotic study of culture, especially in poetry and literature, is an established academic ﬁeld, it has been only in the last two decades when scholars begun to analyse the ways material processes and forces shape and being shaped by cultural representations and aesthetics (Stein and Swedenburg 2005).

조직문화와 고객지향성 간 관계에서 조직애착의 매개효과에 대한 연구 (2016)

This study analyzed how flight attendants’ organizational culture affects their organizational attachment and customer orientation concretely, and also examined whether the organizational attachment had a mediating effect in influencing relationship between the organizational culture and the customer orientation. The derived results are summarized as follows. Firstly, as a result of analyzing the effect of flight attendants’ organizational culture on their organizational attachment, among sub factors composing the organizational culture, progressive culture, relational culture and hierarchical culture appeared to have a positively significant effect on the organizational attachment. Secondly, as a result of analyzing the effect of flight attendants’ organizational attachment on customer orientation, the organizational attachment appeared to have a positively significant effect on the customer orientation. Thirdly, as a result of analyzing the effect of flight attendants’ organizational culture on customer orientation, all sub factors composing the organizational culture appeared to have a positively significant effect on the customer orientation. Fourthly, as a result of analyzing the mediating effect of the organizational attachment in the relation between flight attendants’ organizational culture and customer orientation, the organizational attachment appeared to completely mediate in the relation between the progressiveness culture and the customer orientation. Finally, in the influencing relationship between the organizational culture and the customer orientation, hierarchical culture appeared to have a greater effect on customer orientation the case of full service carriers, but relational culture appeared to have a greater effect on customer orientation the case of low cost carriers.
Preparation of a W/scCO<sub>2</sub> Microemulsion Using Fluorinated Surfactants (2002)

Formation of water (W) in supercritical carbon dioxide (scCO2) (W/scCO2) type microemulsions was examined using four hybrid surfactants, the sodium 1-oxo-1-[4-(tridecafluorohexyl)phenyl]-2-alkanesulfonates (FC6-HCn, n = 2, 4, 6, and 8), which have a hydrocarbon chain of different length and a fluorocarbon chain in one molecule and an Aerosol-OT (AOT) analogue fluorinated twin tail type surfactant, sodium bis(1H,1H,2H,2H-heptadecafluorodecyl)-2-sulfosuccinate (8FS(EO)2). For comparison AOT was also used. The hybrid type surfactants (FC6-HCn) gave a transparent single phase, identified as a W/scCO2 microemulsion, with a water-to-surfactant molar ratio, W0c < 7, irrespective of hydrocarbon chain length. The fluorinated AOT analogue also yielded a transparent single phase, again identified as a W/scCO2 microemulsion, with a W0c value close to 32one of the highest ever reported. The aqueous core in the 8FS(EO)2 reversed micelle was examined by FT-IR spectra using D2O. The spectra revealed that the aqueous core swells on addition of water and shrinks with increase in pressure. The remarkable ability of 8FS(EO)2 to form a W/scCO2 microemulsion would be brought about by its high adsorption capacity and its excellent facility to lower the water/scCO2 interfacial tension, in addition to a low interaction and strong steric repulsion between its CO2-philic groups.
A trapped field of 17.6 T in melt-processed, bulk Gd-Ba-Cu-O reinforced with shrink-fit steel (2014)

The ability of large-grain (RE)Ba2Cu3O7−δ ((RE)BCO; RE = rare earth) bulk superconductors to trap magnetic fields is determined by their critical current. With high trapped fields, however, bulk samples are subject to a relatively large Lorentz force, and their performance is limited primarily by their tensile strength. Consequently, sample reinforcement is the key to performance improvement in these technologically important materials. In this work, we report a trapped field of 17.6 T, the largest reported to date, in a stack of two silver-doped GdBCO superconducting bulk samples, each 25 mm in diameter, fabricated by top-seeded melt growth and reinforced with shrink-fit stainless steel. This sample preparation technique has the advantage of being relatively straightforward and inexpensive to implement, and offers the prospect of easy access to portable, high magnetic fields without any requirement for a sustaining current source.

Abstract The author presents sight rules to be used in judging advertising creativity. They can be followed by anyone but are particularly applicable to new graduates entering the field of marketing. Each rule is discussed briefly using examples as illustrations wherever possible. The rules are: (1) make sure that the advertising adheres to the creative strategy; (2) make sure the advertising is directed to the right audience; (3) make sure the advertising is single-minded; (4) make sure that you know what the creative people have in mind; (6) make sure the advertising technique doesn't overpower the message; (6) separate personal prejudices from judgement decisions; (7) make sure the advertising doesn't change the product image; (8) have faith.
Application of signal sparse decomposition in the detection of partial discharge by ultrasonic array method (2015)

The detection of partial discharge of power transformer is important for the safe operation of a power system. The direction of arrival is an important part of ultrasonic array detection. Classic DOA estimation algorithms based on subspace analysis do not perform well under the conditions of low SNR and small snapshot numbers. The problem with using an improved algorithm is that it requires a huge amount of calculation. In this paper sparse signal decomposition is applied to spatial spectrum estimation. The authors derived the model of array signal direction finding by the use of matching pursuit algorithm, setting up overcomplete dictionaries for different types of sensor array and simulating different types of sensor array receiving signals. Simulations and experiments show that direction finding based on MP decomposition method performs better than using the MUSIC algorithm under the conditions of low SNR and small snapshot numbers, and that the influence of array types is less.
Boundary scan with built-in self-test (1989)

The authors propose a way to merge boundary scan with the built-in self-test (BIST) of printed circuit boards. Their boundary-scan structure is based on Version 2.0 of the Joint Task Action Group's recommendations for boundary scan and incorporates BIST using a register based on cellular automata (CA) techniques. They examine test patterns generated from this register and the more conventional linear-feedback shift register. The advantages of the CA register, or CAR, are its modularity, which allows modification without major redesign, its higher stuck-at fault coverage, and its higher transition fault coverage.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Degradation of collagen in the bone‐resorbing compartment underlying the osteoclast involves both cysteine‐proteinases and matrix metalloproteinases (1992)

The site of action of cysteine-proteinases (CPs) and matrix metalloproteinases (MMPs) in the degradation of bone collagen by osteoclasts was investigated by evaluating the effects of the CP-inhibitor trans-epoxy-succinyl-L-leucylamido (4-guanidino)-butane (E-64) and the MMP-inhibitor N-(3-N-benzyloxycarbonyl amino-1-R-carboxypropyl)-L-leucyl-O-methyl-L-tyrosine N-methylamide (Cl-1) in an in vitro model system of PTH-stimulated mouse calvaria. In the presence of each of the two inhibitors a large area of collagen free of mineral crystallites was seen adjacent to the ruffled border of the osteoclasts. Following a culture period of 24 h this area proved to be about 10 times larger in inhibitor-treated explants than in controls. Moreover the percentage of osteoclasts in close contact with such demineralized bone areas appeared to be significantly higher in inhibitor-treated explants than in control specimens (60% and 5%, respectively). These effects were not apparent when the osteoclastic activity was inhibited with calcitonin. No significant differences were found between the effects of the two inhibitors, E-64 and Cl-1. Our observations indicate that under the influence of inhibitors of MMPs and CPs demineralization of bone by osteoclasts proceeded up to a certain point whereas matrix degradation was strongly inhibited. It is concluded that within the osteoclastic resorption lacuna both CPs and MMPs participate in the degradation of the collagenous bone matrix.
Temporal variation in photoluminescence from single InGaN quantum dots (2004)

We report measurements of optical transitions in single III/V (InGaN) quantum dots as a function of time. Temporal fluctuations in microphotoluminescence peak position and linewidth are demonstrated and attributed to spectral diffusion processes. The origin of this temporal variation is ascribed to randomly generated local electric fields inducing a Stark shift in the optical emission peaks of the InGaN quantum dots.
Breast tumor kinase and extracellular signal-regulated kinase 5 mediate Met receptor signaling to cell migration in breast cancer cells (2010)

These results have identified Brk and ERK5 as important downstream effectors of Met signaling to cell migration. Targeting ERK5 kinase activity or inhibiting the formation of Brk/ERK5 complexes may provide an additional means of blocking cell migration associated with breast cancer progression to metastasis.
