FemtoCaching: Wireless Content Delivery Through Distributed Caching Helpers (2013)

Video on-demand streaming from Internet-based servers is becoming one of the most important services offered by wireless networks today. In order to improve the area spectral efficiency of video transmission in cellular systems, small cells heterogeneous architectures (e.g., femtocells, WiFi off-loading) are being proposed, such that video traffic to nomadic users can be handled by short-range links to the nearest small cell access points (referred to as “helpers”). As the helper deployment density increases, the backhaul capacity becomes the system bottleneck. In order to alleviate such bottleneck we propose a system where helpers with low-rate backhaul but high storage capacity cache popular video files. Files not available from helpers are transmitted by the cellular base station. We analyze the optimum way of assigning files to the helpers, in order to minimize the expected downloading time for files. We distinguish between the uncoded case (where only complete files are stored) and the coded case, where segments of Fountain-encoded versions of the video files are stored at helpers. We show that the uncoded optimum file assignment is NP-hard, and develop a greedy strategy that is provably within a factor 2 of the optimum. Further, for a special case we provide an efficient algorithm achieving a provably better approximation ratio of 1-(1-1/d ) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sup> , where d is the maximum number of helpers a user can be connected to. We also show that the coded optimum cache assignment problem is convex that can be further reduced to a linear program. We present numerical results comparing the proposed schemes.
[Expression of basic fibroblast growth factor and its double receptors in laryngeal squamous cell carcinoma and its significance]. (2006)

碱性成纤维细胞生长因子（basic fibroblast growth factor,bFGF）通过由4个高亲合力酪氨酸激酶受体（fibroblast growth factor receptor,FGFR）和细胞表面的硫酸乙酰肝素蛋白多糖（heparan sulfate proteoglycans,HSPG）组成的双受体系统发挥生物活性，
Plasma Membrane Calcium Pump (PMCA4)-Neuronal Nitric-oxide Synthase Complex Regulates Cardiac Contractility through Modulation of a Compartmentalized Cyclic Nucleotide Microdomain (2011)

Identification of the signaling pathways that regulate cyclic nucleotide microdomains is essential to our understanding of cardiac physiology and pathophysiology. Although there is growing evidence that the plasma membrane Ca(2+)/calmodulin-dependent ATPase 4 (PMCA4) is a regulator of neuronal nitric-oxide synthase, the physiological consequence of this regulation is unclear. We therefore tested the hypothesis that PMCA4 has a key structural role in tethering neuronal nitric-oxide synthase to a highly compartmentalized domain in the cardiac cell membrane. This structural role has functional consequences on cAMP and cGMP signaling in a PMCA4-governed microdomain, which ultimately regulates cardiac contractility. In vivo contractility and calcium amplitude were increased in PMCA4 knock-out animals (PMCA4(-/-)) with no change in diastolic relaxation or the rate of calcium decay, showing that PMCA4 has a function distinct from beat-to-beat calcium transport. Surprisingly, in PMCA4(-/-), over 36% of membrane-associated neuronal nitric-oxide synthase (nNOS) protein and activity was delocalized to the cytosol with no change in total nNOS protein, resulting in a significant decrease in microdomain cGMP, which in turn led to a significant elevation in local cAMP levels through a decrease in PDE2 activity (measured by FRET-based sensors). This resulted in increased L-type calcium channel activity and ryanodine receptor phosphorylation and hence increased contractility. In the heart, in addition to subsarcolemmal calcium transport, PMCA4 acts as a structural molecule that maintains the spatial and functional integrity of the nNOS signaling complex in a defined microdomain. This has profound consequences for the regulation of local cyclic nucleotide and hence cardiac β-adrenergic signaling.
Copolymerization of (Meth)acrylates with Olefins Using Activators Regenerated by Electron Transfer for Atom Transfer Radical Polymerization (ARGET ATRP) (2008)

Abstract Summary: Controlled copolymerization of polar (meth)acrylates with non‐polar olefin monomers (1‐octene, norbornene, vinylcyclohexane) was studied by ARGET (activators regenerated by electron transfer) ATRP (atom transfer radical polymerization). When a normal ATRP of n ‐butyl acrylate ( n BA) and 1‐octene was conducted, the polymerization resulted in relatively low conversion, limited control over the polymerization process and high polydispersity (PDI > 1.6). This was due to formation of a dormant species, by reaction of 1‐octene radicals with Cu(II) deactivator, that could not be reactivated. However, in ARGET ATRP with 10 ppm amounts of Cu‐based catalyst, higher yields and a better controlled copolymerization was obtained (PDI < 1.4), because the low concentration of Cu(II) deactivator reduced the formation of the non‐reactive dormant species. The influence of the amount of Cu catalyst, ligand structure, initiators with different halogens, the reaction temperature, and monomer feed ratio were also investigated for ARGET ATRP. In copolymerization of (meth)acrylates with non‐polar alkenes, the level of control and the total conversion in ARGET ATRP were higher than those for normal ATRP.
관광상품의 지각된 가치가 관광만족에 미치는 영향과 한류의 조절효과 (2012)

The primary purpose of this study was to examine the effect of perceived values of tourist products on customer satisfaction. It also aimed to demonstrate the moderating effect of Hanryu on the relationship between perceived values and customer satisfaction. Further more, this study made an effort to discover which type of Hanryu, Korean drama/movie or Korean pop music, had more influence on this relationship. First of all, perceived values had a significant effect on customer satisfaction. Specifically emotional values of tourist products had stronger influence on customer satisfaction than functional values. However, when the degree of liking Hanryu was put in as a moderating variable, functional values had greater effect on customer satisfaction than emotional values. Moreover, regardless of the type of Hanryu preferred between Korean drama/ movie and Korean pop music, functional values had greater influence on customer satisfaction than emotional values, thus partly supporting the hypothesis. Implications and limitations of this study were discussed.
NBC-Universal Uses a Novel Qualitative Forecasting Technique to Predict Advertising Demand (2008)

NBC-Universal (NBCU), a subsidiary of the General Electric Company (GE), implemented a novel demand prediction and analysis system to support its annual upfront market. The upfront market is a brief period in late May when the television networks sell a majority of their on-air advertising inventory. The system uses an innovative combination of the Delphi method and the Grass Roots forecasting methodology to estimate demand for television commercial time. We embedded this forecasting methodology within a workflow system that automates the demand estimates gathering process and seamlessly integrates into NBCU's existing sales systems. Since 2004, over 200 sales and finance personnel at NBCU have been using the system to support sales decisions during the upfront market when NBCU signs advertising deals worth over $4.5 billion. The system enables NBCU to sell and analyze pricing scenarios across all of NBCU's television properties with ease and sophistication, while predicting demand with a high accuracy. NBCU's sales leaders credit the system with having given them a unique competitive advantage.
Viscoelastic orthorhombic full wavefield inversion: Development of multiparameter inversion methods (2011)

Full wavefield inversion (FWI) requires careful and accurate forward modeling in order to yield meaningful results. To obtain high fidelity wave propagation solutions, viscoelastic and anisotropic wave equations must be employed in order to account for dissipative and fractured media. An accurate and efficient time‐domain method for viscoelastic wavefield simulation and inversion in orthorhombic media has been developed. The inversion engine computes gradients for both the velocity models as well as the attenuation (Q) models. The objective of this study is to present frameworks for multi‐parameter FWI, isolate key pitfalls related to parameter sensitivity and computational cost, and propose potential solutions.
Expression of individual lamins in basal cell carcinomas of the skin (2001)

In this study we used a unique collection of type specific anti-lamin antibodies to study lamin expression patterns in normal human skin and in skin derived from patients with basal cell carcinomas (BCCs). Lamin expression in serial sections from frozen tissue samples was investigated by single and double indirect immunofluorescence. In normal skin, lamin A was expressed in dermal fibroblasts and in suprabasal epithelial cells but was absent from all basal epithelial cells. Lamin C was expressed in dermal fibroblasts, suprabasal epithelial cells and a majority of basal epithelial cells. However, lamin C was not expressed in quiescent basal epithelial cells. Lamin B1 was expressed in all epithelial cells but was not expressed in dermal fibroblasts. Finally, lamin B2 was expressed in all epithelial cells but was not expressed in dermal fibroblasts. Finally, lamin B2 was expressed in all cell types in normal skin. Lamin expression was also investigated in a collection of 16 BCCs taken from a variety of body sites. Based upon patterns of lamin expression the BCCs were classified into four groups: A-negative (10/16 tumours), C-negative (5/16 tumours), A/C-negative (1/16 tumours) and A/B2-negative (1/16 tumours). Lamin expression was also compared to cell proliferation index by staining serial sections with the proliferation marker Ki67. 9/10 of the lamin A negative tumours were highly proliferative, whereas 4/5 of the lamin C negative tumours were slow growing. Thus as a general rule absence of lamin A was correlated with rapid growth within the tumour, while absence of lamin C was correlated with slow growth within the tumour. Our data supports the hypothesis that lamin A has a negative influence on cell proliferation and its down regulation may be a requisite of tumour progression.
Paper Doll Parsing: Retrieving Similar Styles to Parse Clothing Items (2013)

Clothing recognition is an extremely challenging problem due to wide variation in clothing item appearance, layering, and style. In this paper, we tackle the clothing parsing problem using a retrieval based approach. For a query image, we find similar styles from a large database of tagged fashion images and use these examples to parse the query. Our approach combines parsing from: pre-trained global clothing models, local clothing models learned on the fly from retrieved examples, and transferred parse masks (paper doll item transfer) from retrieved examples. Experimental evaluation shows that our approach significantly outperforms state of the art in parsing accuracy.
Drugs and Valvular Heart Disease (2007)

In 1997, Connolly et al. reported that both racemic fenfluramine (Pondimin) and dexfenfluramine (Redux) were associated with valvular heart disease.1 The valvular abnormalities seen in patients treated with these agents were distinctive. On echocardiography, leaflet thickening as well as chordal thickening and retraction were observed. Surgically removed valves were noted to have a glistening white surface, with histologic evidence of a plaque-like process extending along the leaflet surfaces and encasing the chordae tendineae. These findings were similar to those in patients with heart-valve damage induced by serotonin-secreting carcinoid tumors.1 This association of racemic fenfluramine and dexfenfluramine with valvular heart disease . . .
Analysis of variation of neutral point potential in neutral-point-clamped voltage source PWM inverters (2002)

The authors present the analysis of the neutral-point potential variation of the neutral-point-clamped voltage source PWM (pulse-width-modulation) inverter (NPC-VSI) for AC motor drives and static VAr compensators (SVC). The potential variation is analyzed with the focus on the current flowing out of or into the neutral point of the DC link. The theoretical minimum capacity of the DC link capacitors is discussed for its application to both a vector-controlled induction motor system of 2.2 kW and a SVC system of 10 MVA, 6.6 kV, 60 Hz. It is shown that the proposed control scheme makes it possible to suppress the neutral-point potential variation within a few percent, so that the total capacity of the DC link capacitors in the NPC-VSI is almost the same as that in the conventional voltage source inverter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis and Excited-State Properties of a Novel Ruthenium Nucleoside:  5-[Ru(bpy)<sub>2</sub>(4-m-4‘-pa-bpy)]<sup>2+</sup>-2‘-deoxyuridine (1999)

The synthesis and photophysical properties of a novel ruthenium-modified nucleoside are reported. The key synthetic step to 5-[Ru(bpy)2(4-m-4‘-pa-bpy)]2+-2‘-deoxyuridine involves the Pd(0)-catalyzed cross-coupling of a propargylamine-derivatized Ru(bpy)32+ and 3‘,5‘-dibenzoyloxy-2‘-deoxy-5-iodouridine. The long-lived 3MLCT excited state (1300 ns) of 5-[Ru(bpy)2(4-m-4‘-pa-bpy)]2+-2‘-deoxyuridine has an emission maximum centered at 640 nm. Step-scan Fourier transform infrared (S2FTIR) time-resolved spectroscopy reveals the excited-state electron to be localized on the modified bipyridine with the excited-state dipole oriented toward the 2‘-deoxyuridine.
CHARACTERIZATION AND DESIGN OF MILLIMETER-WAVE FULL-BAND WAVEGUIDE-BASED SPATIAL POWER DIVIDER/COMBINER (2014)

The design and implementation of millimeter-wave full-band waveguide-based spatial power divider/combiner are presented in this paper. The divider/combiner is based on a compact waveguide- to-microstrip (Wg-Ms) probe-array transition structure, providing full-band frequency coverage and low insertion loss. E-cient design and analysis method for this type of power divider/combiner is developed using spectral domain method combined with the image theory. Ka-band two-way (1 £ 2) and four- way (2 £ 2) power combining structures are analyzed and optimized. The performances of the both optimized power dividers/combiners are evaluated by experiments in back-to-back conflgurations. The measured overall insertion loss for the 1£2 power divider/combiner is better than 1.4dB over the entire Ka-band, which demonstrates the low-loss performance of the divdier/combiner. The optimized 2 £ 2 power divider/combiner shows a same performance as the 1 £ 2 structure without any degradation in operating bandwidth and insertion loss.

An aperture-matched compact range feed horn design (1985)

The moment method and the uniform geometrical theory of diffraction are used to obtain two separate solutions for the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane far field pattern of an aperture-matched horn antenna. This particular horn antenna consists of a standard pyramidal horn with the following modifications: a rolled edge section attached to the aperture edges and a curved throat section. The resulting geometry provides significantly better performance in terms of the pattern, impedance, and frequency characteristics than normally obtainable. The moment method is used to calculate the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane pattern and voltage standing-wave ratio (VSWR) of the antenna. However, at higher frequencies, the moment method requires large amounts of computation time. On the other hand, the uniform geometrical theory of diffraction provides a quick and efficient high frequency solution for the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane field pattern. In fact, the uniform geometrical theory of diffraction may be used to initially design the antenna; then the moment method may be applied to "fine tune" it. In both methods, a two-dimensional <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane model of the antenna is used, but these two-dimensional solutions yield excellent agreement with measured data of the actual three-dimensional antenna. This procedure has been successfully applied to design a compact range feed horn.
On the High Energy Product of Fe-Pt Permanent Magnet Alloys (1983)

The relations between permanent magnetic properties and microstructures of Fe-34-67.5 at%Pt binary alloys were investigated using a recording fluxmeter, X-ray diffraction and electron microscopy. The excellent permanent magnetic properties have been obtained by water-quenching from a temperature in the γ phase range and subsequent reheating at a lower temperature in the γ1 phase range. A typical Fe-38.5 at%Pt alloy exhibits the highest value of maximum energy product of 159 kJ·m−3(20 MG·Oe), with a coercive force of 340 kA·m−1(4.3 kOe) and a residual flux density of 1.08 T(10.8 kG).It is presumed that the excellent permanent magnetic properties are related to the band microstructure of the γ1 order phase with the L10-type structure and a high crystal magnetic anisotropy.
Superconductivity and Lattice Parameters in (La1−xSrx)2CuO4−δ Solid Solution System (1987)

Abstract The superconducting critical temperature TC increased with increase in x in (La1−xSrx)2CuO4−δ associated with the shortening of the Cu–O bond in the basal plane and the elongation of the lattice along the c-axis in the K2NiF4. structure. The results are discussed in terms of two-dimensional itinerant band formation of Cu:dx2-y2–O:pσ bond.
Different Patterns of Epstein-Barr Virus Latency in Endemic Burkitt Lymphoma (BL) Lead to Distinct Variants within the BL-Associated Gene Expression Signature (2012)

Epstein-Barr virus (EBV) is present in all cases of endemic Burkitt lymphoma (BL) but in few European/North American sporadic BLs. Gene expression arrays of sporadic tumors have defined a consensus BL profile within which tumors are classifiable as "molecular BL" (mBL). Where endemic BLs fall relative to this profile remains unclear, since they not only carry EBV but also display one of two different forms of virus latency. Here, we use early-passage BL cell lines from different tumors, and BL subclones from a single tumor, to compare EBV-negative cells with EBV-positive cells displaying either classical latency I EBV infection (where EBNA1 is the only EBV antigen expressed from the wild-type EBV genome) or Wp-restricted latency (where an EBNA2 gene-deleted virus genome broadens antigen expression to include the EBNA3A, -3B, and -3C proteins and BHRF1). Expression arrays show that both types of endemic BL fall within the mBL classification. However, while EBV-negative and latency I BLs show overlapping profiles, Wp-restricted BLs form a distinct subgroup, characterized by a detectable downregulation of the germinal center (GC)-associated marker Bcl6 and upregulation of genes marking early plasmacytoid differentiation, notably IRF4 and BLIMP1. Importantly, these same changes can be induced in EBV-negative or latency I BL cells by infection with an EBNA2-knockout virus. Thus, we infer that the distinct gene profile of Wp-restricted BLs does not reflect differences in the identity of the tumor progenitor cell per se but differences imposed on a common progenitor by broadened EBV gene expression.
Role of Tumor Necrosis Factor-α in Sensorineural Hearing Loss after Bacterial Meningitis (2005)

Tumor necrosis factor-alpha plays an important role in cochlear injury after bacterial meningitis. Blockade of tumor necrosis factor-alpha reduces postmeningitic hearing loss and cochlear injury. Induction of meningitis with intrathecal tumor necrosis factor-alpha also resulted in hearing loss and cochlear injury similar to bacterial meningitis.
Integrating Context-Awareness with reminder tools (2016)

People use reminders to recall tasks to-do. But sophisticated enough tools are unavailable. Context-Awareness in mobile computing is more engaging area in gathering information about the user's current situation and would be ideal to integrate with the reminders to generate context-aware reminder where rich context is used to identify when a reminder should be presented to its recipient. Here we have proposed a model to integrate context-awareness with reminder's decision making process and develop a Context-Aware reminder. In this research more focus has put on capturing user context using technologies like IoT. Context is captured under five categories; Location, User Activity, User Preference, Identity of the User and Date and Time. Also developed a context representing model and processing context data to infer valuable information in a mobile environment. Then a conceptual framework for a context-aware reminder has presented and finally “RemindMe”, an android app has developed as the proof of concept.
