VoIP services with embedded CAC over cable modem systems (2005)

VoIP (voice over Internet protocol) technology has rapidly been growing up recently, which transmits voice packets by using the user datagram protocol (UDP). VoIP quality is difficult to expect because it is hard to predict the influence of packet delay, packet lose, packet error, etc. This paper proposes an embedded call admission control (CAC) mechanism by applying real-time transfer protocol (RTP) and the real-time control protocol (RTCP) for VoIP services over hybrid fiber/coaxial (HFC) networks. The proposed CAC mechanism is evaluated by the impact of the various traffic load in cable modem termination system (CMTS), which estimates how VoIP quality satisfies the user's requirements under different constrains on cable networks. We discuss VoIP CAC mechanism for the upstream channel according to the data over cable service interface specifications (DOCSIS) version 1.1 and particularly consider G.723.1 voice packets at the transmission rate of 6.3 kbps. The performance measurement of the proposed embedded CAC mechanism is obtained by simulation experiments under various network constrains, which includes throughput, packet dropping ratio and call blocking ratio. Obviously this paper provides an efficiency and fast method for CMTS to decide how many calls can be accepted.

<title>Imaging Of The Electrical Conductivity And Permittivity Inside A Patient: A New Computed Tomography (CT) Technique</title> (1979)

A new CT imaging technique is described. It does not employ x rays; instead, weak electrical currents are passed through the patient to map out the electrical properties of the tissues. It is expected that the images will ultimately have sufficient precision and resolution to be of clinical value.
Toward a Network Telemetry Framework (2018)

This document suggests the necessity of an architectural framework for
network telemetry in order to meet the current and future network
operation requirements. The defining characteristics of network
telemetry shows a clear distinction from the conventional network OAM
concept; hence the network telemetry demands new techniques and
protocols. This document clarifies the terminologies and classifies
the categories and components of a network telemetry framework. The
requirements, challenges, existing solutions, and future directions
are discussed for each category. The network telemetry framework and
the taxonomy help to set a common ground for the collection of related
works and put future technique and standard developments into
perspective.
Issues Related to Teaching Art from a Feminist Point of View (1990)

In this paper, the author suggests that a social action position be included with other ap proaches that have been advocated to effect desirable changes in theory and practice re lated to teaching from a feminist point of view. Five goals for multicultural education are com pared with three feminist approaches to art teaching. A fourth feminist approach to art teaching that incorporates theories about fem inist aesthetics and social is discussed and women's art from the past and contemporary feminist visions are used to amplify this dis cussion.
Cell Surface Membrane Proteins as Personalized Biomarkers: Where we Stand and Where we are Headed (2013)

Personalized medicine requires the development of a wide array of biomarker diagnostic assays, reflecting individual variations and thus allowing tailored therapeutic interventions. Membrane proteins comprise approximately 30% of total human proteins; they play a key role in various physiological functions and pathological conditions, although, currently, only a limited number of membrane proteins are applied as biomarkers. In many normal tissues, cell surface membrane proteins are not easily accessible for diagnostic sampling, and tumor-derived membrane preparations - while serving as potential tumor biomarkers - may not reflect physiological protein expression. In addition to post-translational modifications, which may include glycosylation, phosphorylation and lipid modifications, the trafficking of membrane proteins is also regulated. Moreover, a tight cellular quality control monitors membrane protein maturation, and continuous removal and reinsertion, involving special signaling systems, occurs in many cases. However, cell surface membrane proteins already serve as valuable prognostic and predicative biomarkers, for example, in hematological and immunological diseases, by the determination of the cluster of differentiation markers. In this review, we demonstrate the relevance of cell surface membrane biomarkers in various diseases and call attention to the potential application of red blood cell (erythrocyte) membrane proteins in this regard. Surprisingly, red blood cells express hundreds of membrane proteins, which seem to reflect a general genetic and regulatory background, and may serve as relatively stable and easily accessible personalized membrane biomarkers. Quantitative membrane protein detection in red blood cells by flow cytometry may bring a breakthrough in this regard.

Agro-process intensification: soilborne micro-bioreactors with nitrogen fixing bacterium <i>Azospirillum brasilense</i> as self-sustaining biofertiliser source for enhanced nitrogen uptake by plants (2012)

Abstract A new application of agro-process intensification is described for nitrogen fixation by Azospirillum brasilense supported within the pores of sulphonated-neutralised polyHIPE polymers (PHPs) which are highly hydrophilic, elastic, crosslinked and ionic with nano-structured pore walls. These bioactive macroscopic polymer particles, when used as soil additives act as micro-bioreactors within the soil and facilitate the interactions between plant roots, root exudates, water, nutrients and bacteria (reactive components), because plant roots penetrate into these micro-bioreactors which simultaneously absorb water and nutrients while generating biofertiliser through the nitrogen fixing bacteria within them. Hence, these soil additives act as synthetic rhizosphere (SRS). In greenhouse experiments, it is shown that the presence of the bioactive SRS at 0.5 wt% level in the soil without any fertiliser addition increases the dry grass shoots by 9.6%, 9.5%, 40% and 145% after 3, 6, 9 and 12 weeks of growth, respectively, compared to grass grown with no SRS or bacteria. Progressive yield enhancement with Azospirillum brasilense supported on PHPs is due to reduction of soil nutrients thus switching nitrogen fixing bacterium from consumption to production of nitrogen. The environmental impact and sustainability of SRS media are also considered and compared with other soil additives: super absorbent polymers and biochar.
Non-Gaussian Statistical Timing Analysis Using Second-Order Polynomial Fitting (2008)

For nanometer manufacturing, process variation causes significant uncertainty for circuit performance verification. Statistical static timing analysis (SSTA) is thus developed to estimate timing distribution under process variation. Most existing SSTA techniques have difficulty in handling the non-Gaussian variation distribution and nonlinear dependence of delay on variation sources. To address this problem, we first propose a new method to approximate the max operation of two non-Gaussian random variables through second-order polynomial fitting. With such approximation, we then present new non-Gaussian SSTA algorithms for three delay models: quadratic model, quadratic model without crossing terms (semiquadratic model), and linear model. All the atomic operations (max and sum) of our algorithms are performed by closed-form formulas; hence, they scale well for large designs. Experimental results show that compared to the Monte Carlo simulation, our approach predicts the mean, standard deviation, skewness, and 95% percentile point within 1%, 1%, 6%, and 1% error, respectively.

10 Ghz operation of a phase loop is demonstrated with a travelling-wave type laser-diode optical amplifier, The phase deifference between optical signal pulses and an optical clock is detected by the optical gain modulation in the optical amplifier. The timing clock is extracted from randomly modulated 10Gbit/s optical signal pulses.
Antiapoptotic effect of coagulation factor VIIa (2003)

Binding of factor VIIa (FVIIa) to its cellular receptor tissue factor (TF) was previously shown to induce various intracellular signaling events, which were thought to be responsible for TF-mediated biologic effects, including angiogenesis, tumor metastasis, and restenosis. To understand the mechanisms behind these processes, we have examined the effect of FVIIa on apoptosis. Serum deprivation-induced apoptosis of BHK(+TF) cells was characterized by apoptotic blebs, nuclei with chromatin-condensed bodies, DNA degradation, and activation of caspase 3. FVIIa markedly decreased the number of cells with apoptotic morphology and prevented the DNA degradation as measured by means of TdT-mediated dUTP nick end labeling (TUNEL). The antiapoptotic effect of FVIIa was confirmed by the observation that FVIIa attenuated caspase 3 activation. FVIIa-induced antiapoptotic effect was dependent on its proteolytic activity and TF but independent of factor Xa and thrombin. FVIIa-induced cell survival correlated with the activation of Akt and was inhibited markedly by the specific PI3-kinase inhibitor, LY294002. Blocking the activation of p44/42 mitogen-activated protein kinase (MAPK) by the specific mitogen-induced extracellular kinase (MEK) inhibitor, U0126, impaired modestly the ability of FVIIa to promote cell survival. In conclusion, FVIIa binding to TF provided protection against apoptosis induced by growth factor deprivation, primarily through activation of PI3-kinase/Akt pathway, and to a lesser extent, p44/42 MAPK pathway.
New optimization and management services for 3G wireless networks using CELNET Xplorer (2005)

The increase in complexity of managing new third-generation (3G) data services has led many carriers to focus on new service technologies for optimizing their networks. A particular need exists to have new services that allow apportionment of more network resources for high-speed 3G data while maintaining voice quality. In this paper, we describe a new service based on Cellular Network Explorer (CELNET Xplorer), a non-intrusive tool designed with advanced measurement, analysis, and optimization capabilities for 3G1X, EV-DO, and Universal Mobile Telecommunications System networks. CELNET Xplorer enables service providers to optimize voice and data performance for any group or class of mobile users in the network. Its advanced capability includes temporally and spatially correlated real-time measurements and analyses within a user population. CELNET Xplorer has been used in commercial networks to perform a variety of services and can be used to dynamically balance load changes associated with different data applications.
Novel Culture System of Mesenchymal Stromal Cells from Human Subcutaneous Adipose Tissue (2008)

Accumulating evidence suggests that the delivery of human adipose tissue-derived stromal cells (hASCs) has great potential as regenerative therapy. This was performed to develop a method for expanding hASCs by reducing the amount of serum required. We demonstrate that hASCs were able to expand efficiently in media containing 2% serum and fibroblast growth factor-2. These cells, or low serum cultured hASCs (hLASCs), expressed cell surface markers similar to those on bone marrow-derived mesenchymal stem cells, and could be differentiated into cells of mesenchymal lineage. Of interest, hLASCs secreted higher levels of vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) than hASCs cultured in 20% serum (hHASCs). Moreover, hLASC-conditioned media significantly increased endothelial cell (EC) proliferation and decreased EC apoptosis compared to that obtained from hHASCs or control media only. Antibodies against VEGF and HGF virtually negated these effects. When hASCs were administered into the ischemic hindlimbs of nude rats, hLASCs improved blood flow, increased capillary density, and raised the levels of VEGF and HGF in the muscles as compared with hHASCs. In conclusion, we demonstrate a novel low serum culture system for hASCs, which may have great potential in regenerative cell therapy for damaged organs in the clinical setting.
Laminar-Turbulent Transition Process in Pulsatile Flow (1966)

A controlled ex-vivo study of a simple, sinusoidally oscillating flow in a rigid, constant-area, smooth tube, has produced significant insight into the laminar-turbulent transition phenomenon. The development of turbulence was studied by analyzing the dynamic characteristics of the transition process; i.e., the velocity, growth rate, and intermittency which describe the generation and propagation of turbulent slugs. A new concept, the relaxation time, has been introduced to interpret the effect of a periodic flow component superposed on a mean flow. Classical stability concepts, such as the point of inflection criterion and the Reynolds number, which have been derived from steady-flow analysis, are shown to require modification when applied to an oscillatory flow. Neither the mean nor the instantaneous Reynolds number is a sufficient criterion for determining the transition of laminar to turbulent flow in a pulsatile system. Other necessary criteria are: (1) a source of disturbances, (2) the relaxation time, and (3) the distance from the fluid under observation to the source of disturbance. The concept of relaxation time indicates that slowly oscillating flows of large amplitude tend to suppress or destroy turbulence downstream from sources of disturbance. Qualitative observations are presented which indicate that systolic acceleration may be laminar regardless of the large value of the instantaneous Reynolds number, while diastolic deceleration probably produces disturbed, but not turbulent or highly dissipative, flow.
Determination of Phytase Activity in Feed by a Colorimetric Enzymatic Method: Collaborative Interlaboratory Study (2001)

Fourteen laboratories participated in a collaborative study (coded fyt9404) and 13 laboratories participated in a study (coded fyt9410) to validate a colorimetric assay for determination of microbial phytase activity in feed. For each study, all laboratories received 6 laboratory samples provided by one commercial supplier (phytase activity levels within the range of 200-400 per kg) to be analyzed in duplicate. Method performance was calculated and statistical calculations were executed according to AOAC guidelines. Results from 3 laboratories for study fyt9404 and from one laboratory for study fyt9410 were excluded from statistical analysis because of invalid data determined during initial review by Youden pair, value versus laboratory. For study fyt9404, repeatability relative standard deviation (RSDr) values ranged from 6.2 to 8.6%, and reproducibility relative standard deviation (RSDR) values ranged from 14.1 to 27.6%. No outliers were identified. For study fyt9410, RSDr values ranged from 3.9 to 7.9%, and RSDR values ranged from 14.0 to 20.5%. With outliers excluded, RSDr values ranged from 2.5 to 7.9%, and RSDR values ranged from 14.0 to 20.5%.

A two-stage approach for fully automatic segmentation of venous vascular structures in liver CT images (2009)

The segmentation of the hepatic vascular tree in computed tomography (CT) images is important for many applications such as surgical planning of oncological resections and living liver donations. In surgical planning, vessel segmentation is often used as basis to support the surgeon in the decision about the location of the cut to be performed and the extent of the liver to be removed, respectively. We present a novel approach to hepatic vessel segmentation that can be divided into two stages. First, we detect and delineate the core vessel components efficiently with a high specificity. Second, smaller vessel branches are segmented by a robust vessel tracking technique based on a medialness filter response, which starts from the terminal points of the previously segmented vessels. Specifically, in the first phase major vessels are segmented using the globally optimal graphcuts algorithm in combination with foreground and background seed detection, while the computationally more demanding tracking approach needs to be applied only locally in areas of smaller vessels within the second stage. The method has been evaluated on contrast-enhanced liver CT scans from clinical routine showing promising results. In addition to the fully-automatic instance of this method, the vessel tracking technique can also be used to easily add missing branches/sub-trees to an already existing segmentation result by adding single seed-points.
