Recombinant Human Growth Hormone Treatment in Short Children with Chronic Renal Disease, before Transplantation or with Functioning Renal Transplants: an Interim Report on Five European Studies (1990)

Growth retardation is common in children with chronic renal disease. Final adult height is often reduced, even in children with a functioning renal transplant. The five European studies considered here aim to investigate the efficacy and safety of recombinant human growth hormone therapy (rhGH) in two groups of short children with chronic renal disease. The first group comprises 29 prepubertal children with preterminal chronic renal failure (i.e. before renal transplantation), and the second group comprises 39 prepubertal and pubertal children with functioning renal transplants. The median bone age retardation in the groups at the start of treatment was between 2.2 and 3.7 years; this did not change during the first year of treatment. This interim report concentrates on patients who have been treated for at least 1 year (i.e. 22 children from the first group, and 28 children from the transplant group (15 prepubertal and 13 pubertal children). The median height velocity increased from 4.8 cm/year to 10.0 cm/year in the first group (the chronic renal failure group), from 2.6 cm/year to 6.2 cm/year in prepubertal children with renal transplants and from 3.8 cm/year to 6.7 cm/year in pubertal children with renal transplants. The corresponding changes in height velocity SDS were from -1.3 to 5.1 for the chronic renal failure group and -2.8 to 2.3 for the prepubertal children with renal transplants. Renal function declined in the chronic renal failure group but this decline corresponded to expected progression of the disease. Some of the children with renal transplants showed a decreased renal function, which in most cases was explained by non-compliance or chronic rejection.
Comparative Study on the Political Philosophy of Rousseau and Marx Through Marx’s Communist Manifesto (2015)

There are many ideas in common between Rousseau and Marx, Marx illustrated many political thoughts by a philosophy method, and Rousseau also proposed many propositions after he studied the history of political philosophy. On the field of democracy, Marx tried to connect political thoughts between Kant and Hegel, and Rousseau tried to connect his political thoughts with Plato and Aristotle. Both of Rousseau’s and Marx’s political philosophy can be concluded as products of social cognition.
Consumer Attitudes Toward Online Mass Customization: An Application of Extended Technology Acceptance Model (2011)

This study investigates consumer attitudes toward the online codesign process in mass customization among Korean consumers. The extended Technology Acceptance Model (TAM) was our theoretical framework, along with the constructs of perceived control and enjoyment. Web skill and fashion involvement were integrated as individual characteristics variables in the model. Data from 749 self-administered surveys collected in South Korea were used in this study. Findings indicated that TAM was an effective conceptual framework in explaining consumer response to the online codesign process. The statistically significant results of the perceived enjoyment and control constructs in the extended TAM suggest the importance of their addition to building a model to explain consumer attitudes toward the online codesign process.
Potential Role of Tubulin Acetylation and Microtubule‐Based Protein Trafficking in Familial Dysautonomia (2007)

Familial dysautonomia (FD), a disease of the autonomic and sensory nervous systems, involves mutations in the protein IkappaB kinase complex-associated protein, which is a component of the human Elongator acetylase complex. We suggest a hypothesis in which defects in tubulin acetylation and impairment of microtubule-based protein trafficking may be an underlying cause of FD. In addition, an Arabidopsis homolog of the Elongator subunit ELP3 has been found to bind to the alphabeta-tubulin heterodimer, suggesting that alpha-tubulin may be a cytoplasmic target of Elongator acetylase activity. Studies of synergistic double mutants in yeast indicate a novel role for Elongator in cytoskeletal dynamics, although this is probably because of an effect on actin rather than microtubules. Finally, we suggest that tubulin deacetylase inhibitors may prove useful in the treatment of FD.
Object Identification Using Correlated Orbital Angular Momentum States (2013)

Using spontaneous parametric down-conversion as a source of correlated photon pairs, correlations are measured between the orbital angular momentum (OAM) in a target beam (which contains an unknown object) and that in an empty reference beam. Unlike previous studies, the effects of the object on off-diagonal elements of the OAM correlation matrix are examined. Because of the presence of the object, terms appear in which the signal and idler OAM do not add up to that of the pump. Using these off-diagonal correlations, the potential for high-efficiency object identification by means of correlated OAM states is experimentally demonstrated for the first time. The higher-dimensional OAM Hilbert space enhances the information capacity of this approach, while the presence of the off-diagonal correlations allows for recognition of specific spatial signatures present in the object. In particular, this allows the detection of discrete rotational symmetries and the efficient evaluation of multiple azimuthal Fourier coefficients using fewer resources than in conventional pixel-by-pixel imaging. This represents a demonstration of sparse sensing using OAM states, as well as being the first correlated OAM experiment to measure properties of a real, stand-alone object, a necessary first step toward correlated OAM-based remote sensing.
How well do line drawings depict shape? (2009)

This paper investigates the ability of sparse line drawings to depict 3D shape. We perform a study in which people are shown an image of one of twelve 3D objects depicted with one of six styles and asked to orient a gauge to coincide with the surface normal at many positions on the object's surface. The normal estimates are compared with each other and with ground truth data provided by a registered 3D surface model to analyze accuracy and precision. The paper describes the design decisions made in collecting a large data set (275,000 gauge measurements) and provides analysis to answer questions about how well people interpret shapes from drawings. Our findings suggest that people interpret certain shapes almost as well from a line drawing as from a shaded image, that current computer graphics line drawing techniques can effectively depict shape and even match the effectiveness of artist's drawings, and that errors in depiction are often localized and can be traced to particular properties of the lines used. The data collected for this study will become a publicly available resource for further studies of this type.
Multiresolution and Wide-Scope Depth Estimation Using a Dual-PTZ-Camera System (2009)

Depth information is a critical cue for scene understanding which is very important for video surveillance. Traditional depth estimation approaches based on stereo vision have been well studied in past decades. However, little research is conducted with active cameras. In this correspondence, we discuss the depth estimation problem by employing dual-PTZ (pan/tilt/zoom)-camera system. The contributions of this correspondence includes the following three aspects: 1) we analyze the effect on depth's precision with different PTZ settings; 2) we propose a coarse-to-fine framework to deal with depth estimation problem for complex region; 3) we offer a method to generate mosaic of depth maps to combine depth information from different visual angles and resolutions for large scope. These contributions will widen the usage of dual-PTZ-camera systems to a greater extent. Real-data experimental results show that the proposed approach works well.
Human-machine-interaction in the industry 4.0 era (2014)

The development of Industry 4.0 will be accompanied by changing tasks and demands for the human in the factory. As the most flexible entity in cyber-physical production systems, workers will be faced with a large variety of jobs ranging from specification and monitoring to verification of production strategies. Through technological support it is guaranteed that workers can realize their full potential and adopt the role of strategic decision-makers and flexible problem-solvers. The use of established interaction technologies and metaphors from the consumer goods market seems to be promising. This paper demonstrates solutions for the technological assistance of workers, which implement the representation of a cyber-physical world and the therein occurring interactions in the form of intelligent user interfaces. Besides technological means, the paper points out the requirement for adequate qualification strategies, which will create the required, inter-disciplinary understanding for Industry 4.0.
Photobleaching of a solid photochromic medium by a Gaussian laser beam (2002)

Equations that describe the photobleaching of photochromic layers illuminated by Gaussian laser beams are given. The photochromic samples are made of thionine, triethanolamine, and polyvinyl alcohol and follow simple kinetics law. Spatial absorbance and time-dependent power transmittance are well described by the developed equations. The model is used to calculate the Gaussian dimension of helium-neon laser beams from kinetics data.

Abstract MoO2(acac)2-t-BuOOH system has high activity for oxidative cleavage of tertiary and secondary vic-diols. MoO2(acac)2 cleaves the diols to give cafbonyl compounds in the absence of t-BuOOH.
Group and extended object tracking (1999)

Much of the literature on target tracking is based on the assumption that the observing sensor produces a single point measurement of the target. In practice, this is often not the case. For example, a high resolution sensor may be able to resolve features on an extended target. An analogous problem is that of tracking a group of point targets moving in formation. In both cases, there is a strong interdependency between the individual sensor measurements. In this paper, we handle both of these cases via the same model of individual motion superposed on a common “bulk” effect. A common approach to tracking groups of (dependent) points is to perform the update operation in two distinct steps. The first stage is to find the “best” match or registration between the set of measurements and the predicted pattern, while the second step is to generate an estimate based on the assumption that the selected association is correct. The complexity of managing multiple hypotheses with strongly interdependent groups is usually avoided. However, particularly in stressing scenarios, where the measurement-object association is highly uncertain, a multiple hypothesis approach should have significant advantages. We present a Bayesian multiple hypothesis solution using the bootstrap or particle filter technique in which the probability distribution of the problem state vector is represented by a set of random samples or “particles”. The great advantage of this approach is that the sample set implicitly includes information on previous hypotheses and so awkward hypothesis management is avoided. Only the feasible association hypotheses for the current update of the filter need to be considered for construction of the measurement likelihood function. (4 pages)
Channel Bounding and MAC Protection Mechanisms for 802.11ac (2011)

In this paper, we investigate the problem of channel bounding in wireless local area networks (WLANs). We propose a MAC protection mechanism to combat the hidden node problem on non-primary channels of a basic service set (BSS). Simulation results show that the proposed MAC protection mechanism is effective in combating hidden nodes and improving throughput of 80MHz stations. The proposed scheme has been adopted into the IEEE 802.11ac specification as a mandatory feature. Furthermore, we extend the medium access mechanisms defined in 802.11n for a wider bandwidth, evaluate fairness of the 802.11n PIFS medium access mechanisms, and compare the performance of a dynamic bandwidth scheme with that of a static bandwidth implementation.
Gamma Irradiation Effect on the Transport Critical Current Density of a Bi<sub>1.5</sub>Pb<sub>0.5</sub>Sr<sub>2</sub>Ca<sub>2</sub>Cu<sub>3</sub>O<sub>x</sub> Ceramic (1992)

A Bi 1.5 Pb 0.5 Sr 2 Ca 2 Cu 3 O x ceramic was sequentially irradiated with 60 Co γ-rays at a dose rate of 2.0 MR·h -1 up to a dose of 24 MR at ambient temperature, and the transport critical current density was measured as a function of temperature. The critical current density in zero field was decreased by 2 MR irradiation at temperatures below 65 K, and the radiation effect was more prominent at lower temperature. The radiation effect was enhanced and extended to higher temperature upon further irradiation; the decrease in the critical current density was apparent at temperatures below 77 K after γ-irradiation to 24 MR.
A bifunctional enzyme with lycopene cyclase and phytoene synthase activities is encoded by the <i>carRP</i> gene of <i>Mucor circinelloides</i> (2000)

Using functional analyses in Escherichia coli and Mucor circinelloides, it has been shown that a single M. circinelloides gene (carRP) codes for a protein with two different enzymatic activities, lycopene cyclase and phytoene synthase, which are encoded by independent genes in organisms other than fungi. This gene was identified using complementation tests among different classes of carotenoid mutants of M. circinelloides. The carRP gene product contains two domains: the R domain is located at the N-terminus and determines lycopene cyclase activity; the P domain is located at the C-terminus and displays phytoene synthase activity. The R domain is functional even in the absence of the P domain, while the latter needs the proper R domain conformation to carry out its function. The carRP gene is closely linked to the phytoene dehydrogenase (carB) gene, and the promoter regions of both genes are located within only 446 bp. Northern analyses show a co-ordinated regulation of the expression of both genes by blue light. Several motifs found in this promoter region suggest a bi-directional mode of transcription control.
Intra and inter datacenter networking: The role of optical packet switching and flexible bandwidth optical networking (2012)

This paper discusses prospects and challenges of optical networking designed to meet exponentially growing demands of data traffic. We discuss both intra and inter data-center networking. For intra-datacenter networking, a single arrayed waveguide grating router based optical switch offers fully connected all-to-all parallel interconnection amongst thousands of racks to achieve high throughput and low-latency interconnection in a new flattened network topology. This new interconnection network named LION provides significant performance advantages over other electrical, optical, or hybrid interconnection networks in terms of available bandwidth per channel, end to end latency and throughput. For inter-datacenter networking, we investigate flexible bandwidth elastic optical networks designed to adaptively accommodate bursty and high capacity traffic between the data centers while supporting the traditional traffic in the background. Further, we demonstrate adaptive and real-time control of the spectral assignment and modulation format for each slice while achieving defragmentation to optimize the spectrum utilization under the dynamically varying traffic demands. The paper covers the intra- and inter- datacenter networking architecture, algorithm, control plane and simulation and experimental studies from the network testbed.
An in vivo study of the effect of excimer laser irradiation on degenerate rabbit articular cartilage (1994)

Eighteen adult rabbits with mechanically induced degenerative arthritis of one knee were divided into two groups. The first group underwent arthrotomy and lavage of the arthritic joint. The second group underwent arthrotomy and irradiation of the degenerate articular surface with the Excimer (xenon chloride ultraviolet, 308-nm) laser (Arthrex Arthrolase MAX-10, Germany) in a saline environment. Rabbits from each group were killed at intervals up to 12 weeks for histological and metabolic studies of their articular cartilage. In the control group there was no improvement in the macroscopic or microscopic appearance of the articular surface. In the laser-irradiated group initially there was macroscopic and microscopic smoothing of the fibrillated surface. By 6 weeks the surface had begun to show the reappearance of fibrillation. There was no evidence that there was any increase or decrease in mitotic or metabolic activity in the laser-irradiated group as compared with the controls.

Sixty FiveTbas from sixteen villages in six local government areas of Cross River and Akwa Iborn States of Nigeria were enrolled in the study and given formal teaching on twenty risk factors and their clinical indicators.
Geomechanical and Thermal Responses of Hydrate-Bearing Sediments Subjected to Thermal Stimulation: Physical Modeling Using a Geotechnical Centrifuge (2013)

The geomechanical and thermal responses of sediments can be significantly affected by the dissociation of gas hydrates via various emergent phenomena such as fluid volume expansion, free gas generation, gas migration, and sediment softening. This study explores the geomechanical and thermal responses of hydrate-bearing sediments subjected to thermal stimulation, using physical modeling with a geotechnical centrifuge that enables the simulation of near-seafloor sediment conditions. A water-saturated and CO2 hydrate-bearing sand column was prepared in a large cylindrical pressure vessel, and a linear stress gradient for a near-seafloor condition was created by increasing centrifugal acceleration. The hydrate-bearing sand column was subjected to thermal stimulation, and changes in temperature, pressure, compressional wave velocity (VP), shear wave velocity (VS), and electrical resistance were monitored at various locations across the column. It was found that VP and electrical resistance were good indicators of the presence of free gas, while VS reflected the reduction in shear stiffness, caused by decementation resulting from hydrate dissociation. The thermal diffusivity of hydrate-bearing sediments significantly decreased as the gas hydrate dissociated and free gas saturation increased. Such a process is expected to retard gas production from hydrate deposits. Temporary accumulation of excess pore pressures >200 kPa was observed even in the fine sandy sediment; this excess pressure resulted from the increased capillary pressure exerted by the hydrate formed at the grain contacts, coupled with the continuous hydrate dissociation against pressure diffusion and resulting gas migration. This suggests a possible sediment volume expansion, an uplifting deformation at the seafloor, or a fracture generation in sediments. By contrast, the vanishing of solid hydrate crystals by hydrate dissociation led to decementation and softening of sediments, indicating a possible postdissociation subsidence at the seafloor and at dissociated regions during gas production from hydrate-bearing sediments.
Study on Advanced Visualization Tools In Network Monitoring Platform (2009)

Visualization tools have emerged as a critical component, especially in medical, education, engineering, military and environmental management. These fields have applied the visualization techniques to improve decision making and organization management performance. In recent times, with the advent of Internet and the explosive growth of networking infrastructure on a global scale demand for an intuitive and wholesome approach to visual the network traffic. Complexity of network architecture and insufficient vendor support are the major issues always that are faced by a user in solving a network monitoring problem. Network engineer needs to start on network monitoring by integrating conventional network monitoring tools with an innovative visualization tool, which can provide the network activities that are easily understood by a user. Currently, there are numerous data visualization tools in network monitoring namely network analysis visualization, spinning cube of potential doom (SCPD), visual information security utility for administration live (VISUAL), SeeNet, Cichlid, CyberNet and others. These tools provided useful information about network activities, which important for monitoring purpose. Our work entails the development of an advanced visualization framework to intelligently visualize high volume, real-time network traffic data.
