Analysis of adaptive bandwidth allocation in wireless networks with multilevel degradable quality of service (2004)

A wireless/mobile network supporting multilevel quality of service (QoS) is considered. In such a network, users or applications can tolerate a certain degree of QoS degradation. Bandwidth allocation to users can, therefore, be adjusted dynamically according to the underlying network condition so as to increase bandwidth utilization and service provider's revenue. However, arbitrary QoS degradation may be unsatisfactory or unacceptable to the users, hence resulting in their subsequent defection. Instead of only focusing on bandwidth utilization or blocking/dropping probability, two new user-perceived QoS metrics, degradation ratio and upgrade/degrade frequency, are proposed. A Markov model is then provided to derive these QoS metrics. Using this model, we evaluate the effects of adaptive bandwidth allocation on user-perceived QoS and show the existence of trade offs between system performance and user-perceived QoS. We also show how to exploit adaptive bandwidth allocation to increase system utilization (for the system administrator) with controlled QoS degradation (for the users). By considering various mobility patterns, the simulation results are shown to match our analytical results, demonstrating the applicability of our analytical model to more general cases.
Effect of switching frequency and number of winding layers on copper loss of an inductor (2002)

Power inductor operating in a high frequency switching power converter experiences both core loss and copper loss. It is a common belief that the higher the switching frequency is, the higher will be the inductor loss. In this paper, we demonstrate that this is not the case. In fact the higher the switching frequency, the lower the inductor copper loss. This applies to an inductor with centre-gapped, side-gapped and spacer configurations. In the loss analysis, an optimum number of inductor turns is derived analytically to minimize copper loss incurred by an inductor with side-gapped configuration.
The NeuronalMicrotubule-Associated Protein 1BIs under Homeoprotein Transcriptional Control (2001)

To identify genes regulated by homeoprotein transcription factors in postnatal neurons, the DNA-binding domain (homeodomain) of Engrailed homeoprotein was internalized into rat cerebellum neurons. The internalized homeodomain (EnHD) acts as a competitive inhibitor of Engrailed and of several homeoproteins (Mainguy et al., 2000). Analysis by differential display revealed that microtubule-associated protein 1B (MAP1B) mRNA is upregulated by EnHD. This upregulation does not require protein synthesis, suggesting a direct effect of the homeodomain on MAP1B transcription. The promoter region of MAP1B was cut into several subdomains, and each subdomain was tested for its ability to bind Engrailed and EnHD and to associate with Engrailed-containing cerebellum nuclear extracts. In addition, the activity, and regulation by Engrailed, of each subdomain and of the entire promoter were evaluated in vivo by electroporation in the chick embryo neural tube. These experiments demonstrate that MAP1B promoter is regulated by Engrailed in vivo. Moreover, they show that one promoter domain that contains all ATTA homeoprotein cognate binding sites common to the rat and human genes is an essential element of this regulation. It is thus proposed that MAP1B, a cytoskeleton protein involved in neuronal growth and regeneration, is under homeoprotein transcriptional regulation.
Use of Small-Cell Technologies for Telemedicine (2018)

This chapter presents the small-cell concept and outlines the benefits of leveraging small cells within connected personal health implementations, with a particular focus on personal health systems in the home environment. It provides a more detailed background on personal health system solutions and their current developments in various standardization bodies. The chapter discusses an overview of small cells and their architectural features and describes how small cells could be used as a gateway for personal health systems and the benefits that could be attained from that configuration. The accessibility to mobile services provided over small cells varies according to small-cell ownership, intended coverage area for the small cell, and mobile operator’s business model. Small cells enable relatively improved indoor coverage compared to conventional macrocell coverage mostly by avoiding the wall attenuation encountered in outdoor-to-indoor propagation. The benefits of small cells in terms of hot spot capacity and coverage enhancements are widely known.
Modeling Facet Formation for Non-Planar Thermal Oxidation of Silicon (2001)

A model for simulating 2D and 3D oxide shape for oxidation of non-planar silicon surfaces is presented. The model is based on an idea that the stress dependence of the reaction rate can be anisotropic with respect to the crystallographic orientation of silicon surface. It describes facet formation, observed in liner oxide at the corners of STI (Shallow Trench Isolation). It is also necessary to describe the shape of top STI corner which is critical in determining the MOSFET leakage.
Precursor Dependent Microstructure Evolution and Nonstoichiometry in Nanostructured Cerium Oxide Coatings Using the Solution Precursor Plasma Spray Technique (2010)

A solution precursor plasma spray (SPPS) technique has been used for direct deposition of cerium oxide nanoparticles (CNPs) from various cerium salt solutions as precursors. Solution precursors were injected into the hot zone of a plasma plume to deposit CNP coatings. A numerical study of the droplet injection model has been employed for microstructure development during SPPS. The decomposition of each precursor to cerium oxide was analyzed by thermogravimetric‐differential thermal analysis and validated by thermodynamic calculations. The presence of the cerium oxide phase in the coatings was confirmed by X‐ray diffraction studies. Transmission electron microscopy studies confirmed nanocrystalline (grain size &lt;14 nm) characteristic of the coatings. X‐ray photoelectron spectroscopy studies indicated the presence of a high concentration of Ce 3+ (up to 0.32) in the coating prepared by SPPS. The processing and microstructure evolution of cerium oxide coatings with high nonstoichiometry are reported.
CD2 Distinguishes Two Subsets of Human Plasmacytoid Dendritic Cells with Distinct Phenotype and Functions (2009)

Plasmacytoid dendritic cells (pDCs) are key regulators of antiviral immunity. They rapidly secrete IFN-alpha and cross-present viral Ags, thereby launching adaptive immunity. In this study, we show that activated human pDCs inhibit replication of cancer cells and kill them in a contact-dependent fashion. Expression of CD2 distinguishes two pDC subsets with distinct phenotype and function. Both subsets secrete IFN-alpha and express granzyme B and TRAIL. CD2(high) pDCs uniquely express lysozyme and can be found in tonsils and in tumors. Both subsets launch recall T cell responses. However, CD2(high) pDCs secrete higher levels of IL12p40, express higher levels of costimulatory molecule CD80, and are more efficient in triggering proliferation of naive allogeneic T cells. Thus, human blood pDCs are composed of subsets with specific phenotype and functions.

Should one always connect to the base station with the strongest signal? (2009)

This work considers a network with K transmitters and receivers, where the transmit-receive association is not predetermined. It is thus an interference network where the pairing between transmitters and receivers can be optimized to improve performance. This model is designed to represent a cellular system where each transmitter (mobile) is attempting to determine the best receiver (base-station) to connect to so as to maximize throughput. It is shown that in the two transmit-receive case, it is always better for a user to communicate with the ¿stronger¿ base station, for a network with K > 2 transmitters and receivers, there exists a range of channel realizations for which connecting mobiles with a ¿weaker¿ base station results in a higher network throughput than connecting to the base-station with the ¿stronger¿ signal.
Biochemical identification of new proteins involved in splicing repression at the Drosophila P-element exonic splicing silencer (2015)

Splicing of the Drosophila P-element third intron (IVS3) is repressed in somatic tissues due to the function of an exonic splicing silencer (ESS) complex present on the 5' exon RNA. To comprehensively characterize the mechanisms of this alternative splicing regulation, we used biochemical fractionation and affinity purification to isolate the silencer complex assembled in vitro and identify the constituent proteins by mass spectrometry. Functional assays using splicing reporter minigenes identified the proteins hrp36 and hrp38 and the cytoplasmic poly(A)-binding protein PABPC1 as novel functional components of the splicing silencer. hrp48, PSI, and PABPC1 have high-affinity RNA-binding sites on the P-element IVS3 5' exon, whereas hrp36 and hrp38 proteins bind with low affinity to the P-element silencer RNA. RNA pull-down and immobilized protein assays showed that hrp48 protein binding to the silencer RNA can recruit hrp36 and hrp38. These studies identified additional components that function at the P-element ESS and indicated that proteins with low-affinity RNA-binding sites can be recruited in a functional manner through interactions with a protein bound to RNA at a high-affinity binding site. These studies have implications for the role of heterogeneous nuclear ribonucleoproteins (hnRNPs) in the control of alternative splicing at cis-acting regulatory sites.
Calculation of macrocyclization equilibria for poly(ethylene terephthalate) (1979)

Abstract The cyclization equilibria constant K x is evaluated for the formation of cyclic poly(ethylene terephthalate)s (PET) in the range of degree of polymerization 2 ≤ x ≤ 10 on the basis of an elaborated form of the Jacobson‐Stockmayer theory. According to this theory, K x = W( 0 )·2Γ 0 (1)/(σ cx N A ), where W( r ) is the probability density function for the chain vector r ; Γ 0 (γ) is the probability distribution, when r = 0 of γ = cos Δθ; Δθ being the deviation of the bond angle formed by cyclization from its unconstrained value; σ cx corresponds to the symmetry number of the ring; N A is Avogadro's number. The evaluation of W( r ) is performed in different approximations. The required configurational averages for computing the density distribution W( r ) and the angular correlation factor Γ 0 (1) are obtained by Monte Carlo techniques. The density W ( 0 ) of chain vectors at r = 0 is overestimated by the Gaussian approximation. Values of W( 0 ) calculated in higher approximation lower K x for x &lt; 10. By taking into account the oriental correlation between terminal bonds of the x ‐meric acyclic sequence, K x is lowered additionally by factors of ca. 2,2, 1,3 and 1,1 for x = 4, 5 and 6, respectively. Similar to other polymer chains treated so far, K x is lowered for medium sized chain lengths by taking into account the deviation from Gaussian distribution and angular correlations of chain ends. This result is in contradiction to experimental data, which yield even higher K x ‐values than expected by the classical Jacobson‐Stockmayer theory for medium sized chain lengths. The inclusion of cis ‐ester residues into the all trans ‐ester PET chain only slightly reduces this discrepancy. Structural modifications of the PET chain during cyclization experiments are discussed as a rationale for the deviations from the present theory.

Association of Variations in TPH1 and HTR2B with Gestational Weight Gain and Measures of Obesity (2011)

Serotonin is involved in appetite regulation and energy homeostasis. Recently, it has been reported that 5-hydroxytryptamine receptor 2B (Htr2b) and tryptophan hydroxylase 1 (Tph1) play major role in β-cell proliferation in mouse during pregnancy. We investigated the genetic association of HTR2B and TPH1 with risk of gestational diabetes mellitus (GDM) and measures of obesity, in 869 Korean GDM women and carefully selected 632 nondiabetic control subjects. Six single-nucleotide polymorphisms (SNPs) in HTR2B and ten SNPs in TPH1 were selected for genotyping according to their tagging status. Genetic variants in HTR2B and TPH1 were not associated with the risk of GDM. In GDM women, SNPs of TPH1 were significantly associated with weight gain during pregnancy. In nondiabetic controls, SNPs of TPH1 were associated with waist circumference and BMI. We also found that a variant of TPH1 (rs623580) was associated with BMI in a genome-wide association study comprised of 8,842 subjects. Although genetic variants in HTR2B and TPH1 were not associated with risk of GDM, we found significant association of these variants with measures of obesity. However, further replication studies in a different population are required to confirm our findings.
Experience with a language for writing coherence protocols (1997)

. In this paper we describe our experience with Teapot [7], a domain-specific language for writing cache coherence protocols. Cache coherence is of concern when parallel and distributed computing systems make local replicas of shared data to improve scalability and performance. In both distributed shared memory systems and distributed file systems, a coherence protocol maintains agreement among the replicated copies as the underlying data are modified by programs running on the system. Cache coherence protocols are notoriously difficult to implement, debug, and maintain. Unfortunately, protocols are not off-the-shelf items, as their details depend on the requirements of the system under consideration. This paper presents case studies detailing the successes and shortcomings of using Teapot for writing coherence protocols in two systems. The first system, loosely coherent memory (LCM) [16], implements a particular type of distributed shared memory suitable for dataparallel pr...

Near-field mode profile and refractive index profile using the refracted near-field technique were measured for these waveguides. We demonstrate that the optical properties of this glass remain unchanged during the ion-exchange process.
Fractal-based analysis of optical coherence tomography data to quantify retinal tissue damage (2014)

Our results suggest that the GCL + IPL complex, OPL and OS are more susceptible to initial damage when comparing MDR with control healthy eyes. Fractal analysis provided a better sensitivity, offering a potential diagnostic predictor for detecting early neurodegeneration in the retina.
EOS-Based Downhole Fluid Characterization (2008)

Abstract Downhole fluid analysis (DFA), together with wireline formation testing tools, provides real-time measurements of reservoir fluid properties such as compositions of four or five components/groups and gas/oil ratio (GOR). With the introduction of a new generation of DFA tools that analyze fluids in situ, the accuracy and reliability of the DFA measurements are significantly enhanced. Furthermore, the downhole measurements of live fluid density and viscosity are integrated into the new tools. Direct pressure and temperature measurements of the flowline ensure capture of accurate fluid conditions. To further enhance these advanced features, a new method of downhole fluid characterization based on the equation of state (EOS) approach is proposed in this work. The purpose of this work is to develop a new approach to maximize the value of DFA data and perform quality assurance and/or quality control (QA/QC) of DFA data. The basic inputs from DFA measurements are weight percentages of CO2, C1, C2, C3-C5, and C6+; live fluid density; and viscosity. A new method is developed in this work to delump and characterize the measurements of C3-C5 (C2-C5) and C6+ into full-length compositional data. The full-length compositional data predicted by the new method are compared with the laboratory-measured gas chromatograph (GC) data up to C30+ for more than 1,000 fluids, including heavy oil, conventional oil, volatile oil, rich gas condensate, lean gas condensate, and wet gas. A good agreement is reached. Furthermore, based on the delumped and characterized compositions, an EOS model is established that can be applied to predict fluid phase behavior and physical properties on the basis of DFA data as input. The EOS predictions are validated and compared with the laboratory-measured PVT (pressure/volume/temperature) properties for more than 1,000 fluids. The GOR, formation volume factor (FVF), and density predictions are in good agreement with the laboratory measurements. The established EOS model is then able to predict other PVT properties, and the results are compared with the laboratory measurements in a good accord.

Channel Coding and Link Adaptation (2009)

Link adaptation is fundamental in LTE for the provision of an efficient packet-switched radio interface. Link adaptation dynamically adjusts the transmitted modulation scheme and code rate to match the radio channel conditions, based on channel quality feedback from the UE. This chapter first describes the procedures for the channel quality feedback.It then analyses of the design of the forward error correcting code, beginning by reviewing the main theoretical principles of the channel coding techniques studied for LTE (Convolutional Codes, Turbo Codes and Low-Density Parity-Check Codes). As with UMTS, Turbo codes were also selected for the data channels in LTE. However, a specially-designed contention-free interleaver is introduced in LTE in order to support the high data rates offered. These aspects are described in detail. Finally, the chapter explains how code rate adaptation can be used in LTE to operate Hybrid Automatic Repeat reQuest (HARQ), a combination of ARQ and channel coding which provides more robustness against fading. In particular, the use of incremental redundancy enables the code rate to be reduced progressively by transmitting additional parity information with each retransmission.

Universally Image Partition Regularity (2008)

Many of the classical results of Ramsey Theory, for example Schur's Theorem, van der Waerden's Theorem, Finite Sums Theorem, are naturally stated in terms of image partition regularity of matrices. Many characterizations are known of image partition regularity over ${\Bbb N}$ and other subsemigroups of $({\Bbb R},+)$. In this paper we introduce a new notion which we call universally image partition regular matrices, which are in fact image partition regular over all semigroups and everywhere. We also prove that such matrices exist in abundance.
