Throughput-delay improvement of unslotted CDMA packet radio networks using rate adaptive CLSP (2003)

This paper presents the throughput-delay analysis or a centralized unslotted DS/CDMA packet radio network using rate adaptive channel load sensing protocol (CLSP). CLSP is an access control protocol used to limit the contentions of CDMA unslotted ALOHA radio channel under a certain threshold to improve the system throughput. The rate adaptive extension of CLSP is proposed (i) to compensate the near-far effects and power control difficulty of connectionless packet transmissions under changing channel conditions; (ii) to enhance the system performance and coverage. The analytical model is developed based on a multi-rate loss network model taking into account the impacts of spatial user distributions and radio propagation attenuation. The results show that the rate adaptive CLSP system gains significant improvement in throughput-delay tradeoffs compared to the fixed rate counterpart with the same coverage, offered traffic and QoS requirements.
Engineering a planar NAND cell scalable to 20nm and beyond (2013)

Intel-Micron have recently introduced a scalable planar NAND cell for the 20nm technology. Replacement of conventional wrap floating gate (FG) NAND memory cell with a High-K/Metal gate planar cell that can scale to the 20nm node and beyond was a significant challenge and required comprehensive material and cell exploration and optimization. This paper discusses some of the fundamental cell design issues considered and addressed to arrive at this planar cell technology including the reasoning behind choosing the planar floating gate cell over the nano-crystal cell, and the nitride cell.
Fabricating microgeometry for custom surface reflectance (2009)

We propose a system for manufacturing physical surfaces that, in aggregate, exhibit a desired surface appearance. Our system begins with a user specification of a BRDF, or simply a highlight shape, and infers the required distribution of surface slopes. We sample this distribution, optimize for a maximally-continuous and valley-minimizing height field, and finally mill the surface using a computer-controlled machine tool. We demonstrate a variety of surfaces, ranging from reproductions of measured BRDFs to materials with unconventional highlights.
The case for network witnesses (2008)

Network abuse is prevalent in todaypsilas Internet. To combat abuse, this paper examines a general approach for constructing network protocols based on the use of ldquonetwork witnessesrdquo: tamper-resistant, trusted third parties that reside at network protocol end-points. By providing authentic measurements of network use and by ensuring the correct usage of network protocols, we show how network witnesses can enable fundamentally new protocol designs that can protect networks against malicious use.
Dual damascene trench depth control by Irm/spl trade/: a novel interferometric endpoint system (2003)

Etching dielectric trenches on the wafer for copper interconnect without using a middle etch stop layer is becoming part of mainstream wafer fabrication processes, mainly due to significant lower manufacturing cost and lower effective k-value of the dielectric film stack. In this paper, we present a novel in-situ interferometric technique to control the trench depth for various types of patterned dielectric films, including silicon oxide, FSG (fluorinated silicon glass), low-k CVD Black Diamond/spl trade/, and low k spin-on materials. This paper presents data on etching various dielectric structure trench wafers for both CVD and spin-on low-k materials in Applied Materials MERIE etch reactors. A good correlation between predicted etch depth using interferometric signals and SEM depth data is obtained.
The Challenge of Access Control Policies Quality (2018)

Access Control policies allow one to control data sharing among multiple subjects. For high assurance data security, it is critical that such policies be fit for their purpose. In this paper we introduce the notion of “policy quality” and elaborate on its many dimensions, such as consistency, completeness, and minimality. We introduce a framework supporting the analysis of policies with respect to the introduced quality dimensions and elaborate on research challenges, including policy analysis for large-scale distributed systems, assessment of policy correctness, and analysis of policies expressed in richer policy models.
Fibronectin-guided migration of carcinoma collectives (2017)

Functional interplay between tumour cells and their neoplastic extracellular matrix plays a decisive role in malignant progression of carcinomas. Here we provide a comprehensive data set of the human HNSCC-associated fibroblast matrisome. Although much attention has been paid to the deposit of collagen, we identify oncofetal fibronectin (FN) as a major and obligate component of the matrix assembled by stromal fibroblasts from head and neck squamous cell carcinomas (HNSCC). FN overexpression in tumours from 435 patients corresponds to an independent unfavourable prognostic indicator. We show that migration of carcinoma collectives on fibrillar FN-rich matrices is achieved through αvβ6 and α9β1 engagement, rather than α5β1. Moreover, αvβ6-driven migration occurs independently of latent TGF-β activation and Smad-dependent signalling in tumour epithelial cells. These results provide insights into the adhesion-dependent events at the tumour-stroma interface that govern the collective mode of migration adopted by carcinoma cells to invade surrounding stroma in HNSCC.

ChemInform Abstract: Reaction of Diphenylmethyl Cations in a Strong Acid. Participation of Carbodications with Positive Charge Substantially Delocalized Over the Aromatic Rings. (1988)

Abstract By means of NMR or UV spectroscopic methods and product analysis it is demonstrated on a wide range of substrates that diphenylmethanols such as (I) in strong acids form mesomeric dications such as (II) which on aqueous work‐up yield the products (III); in the case of R: ‐Ph compound (IV) is formed as well in 8.4% yield, obviously from a mesomeric dication (IIa).
String algorithms and data structures (2008)

The string-matching field has grown at a such complicated stage that various issues come into play when studying it: data structure and algorithmic design, database principles, compression techniques, architectural features, cache and prefetching policies. The expertise nowadays required to design good string data structures and algorithms is therefore transversal to many computer science fields and much more study on the orchestration of known, or novel, techniques is needed to make progress in this fascinating topic. This survey is aimed at illustrating the key ideas which should constitute, in our opinion, the current background of every index designer. We also discuss the positive features and drawback of known indexing schemes and algorithms, and devote much attention to detail research issues and open problems both on the theoretical and the experimental side.

Experimental Investigation of the Heat Transfer Performance of Arrays of Round Jets With Sharp-Edged Orifices and Peripheral Effluent: Convective Behavior of Water on a Heated Silicon Surface (2005)

In the present work, deionized water is impinged onto a heated silicon surface using square arrays of round jets. Various numbers of jets and jet diameters are used over a heated area of constant size with the orifice plate height above the heater held constant. In these experiments, the jet orifices are sharp-edged and the fluid exhaust direction is parallel to the heated surface and leaves the chip periphery through a manifold. The resulting temperature and flow data are presented in physical units as well as in groups of dimensionless parameters. A correlation is presented to reasonably predict the experimental results of this study. The techniques used for data reduction and for experimentation, including the construction of the test module, are given in detail, including a numerical conduction simulation based data reduction technique and uncertainty analysis. The results shown include flow rates ranging from 6.1 cc/s to 63.18 cc/s resulting in Reynolds numbers based on orifice diameter ranging from 141 to 6670. Jet diameters investigated in this study range from 377 μm to 1.01 mm, in square arrays of 16 to 324 orifices on an area of 18.52 mm × 18.59 mm. The resulting maximum spatially averaged effective heat transfer coefficient achieved is 7.94 W/cm2K, and the maximum spatially averaged Nusselt number based on jet diameter is 79.4.
Effect of Mechanical Constraint on Tearing Energy of Polymer Membranes (2016)

The role of mechanical constraint on the tearing behavior of perfluorosulfonic acid and polyethylene membranes is examined. A constrained tearing test is employed to measure the tearing energy when the formation of a plastic zone ahead of the tear tip is constrained. It is shown that the tearing energy decreases with increasing constraint associated with a smaller plastic zone and is much lower than the tearing energy with no constraint. Furthermore, it is demonstrated that the tearing rate has a strong effect on the tearing energy when the membrane is unconstrained, but a much smaller effect when the membrane is constrained as the viscoelastic relaxation processes related to the plastic zone are suppressed. The results highlight the significant role of mechanical constraint on the tearing behavior of membranes during both testing and in application. image
Materials in Solar Thermal Collectors (2000)

A procedure for accelerated life testing of solar absorber surfaces was developed within the framework of the working group MSTC (Materials in Solar Thermal Collectors) of the IEASHCP (International Energy Agency Solar Heating and Cooling Programme). The intensive material and micro-climatic investigations on solar thermal collectors and solar systems within the preceding IEA Task 10 (1985 1991) as well as further studies in this field by the group itself formed a basis for this work. Examples of the application of the test procedures will be given. The studies on the micro-climatic data in collectors were carried out at 5 different locations and with various collectors. The ambient climate, the ventilation rate of the collector and the isolation material were identified as main influence parameters. Simulation tools for the optimisation of the micro-climate in order to achieve the most favourable micro-climate in terms of corrosivity and a test procedure for the ventilation rate in collectors were developed and validated. Guidelines for the collector designers were evaluated. The transfer of the accelerated test life testing procedure to the application on anti-reflective and polymeric glazing materials was started.

Natural Antioxidant Extract from Fenugreek (Trigonella foenumgraecum) for Ground Beef Patties (1996)

ABSTRACT Ground beef patties (75% lean) containing synthetic antioxidants, or Fenugreek ( Trigonella foenumgraecum ) extracts were cooked to internal temperature 70°C, and evaluated for storage stability at 4°C. Thiobarbituric acid values of raw or cooked samples containing fenugreek extracts were lower than controls (P&lt;0.05). Fenugreek extracts delayed the induction period of oxidative rancidity. No differences were observed in psychrotrophic bacterial counts, and samples containing fenugreek extracts had lower Hunterlab “a” and higher “b” values. Samples with Fenugreek extracts had better oxidative stability and Fenugreek may be a promising natural antioxidant source.
Learning nonlinear dynamic models (2009)

We present a novel approach for learning nonlinear dynamic models, which leads to a new set of tools capable of solving problems that are otherwise difficult. We provide theory showing this new approach is consistent for models with long range structure, and apply the approach to motion capture and high-dimensional video data, yielding results superior to standard alternatives.

Improvement of purity of produced 15 O beams for OpenPET (2015)

In ion therapy, it is ideal to use radioactive ion beams for in-beam positron emission tomography (PET) imaging in order to visualize the irradiation field for treatment. In cancer treatment with light ions, 15O beam is a good candidate for tumor treating and monitoring the delivery of the dose by (PET) imaging. Moreover, a combination of different positron emitter ions, such as 11C and 15O, might be favorable for a selected clinical situation in the near future for radiation therapy. We have recently produced 15O beams in the Heavy Ion Medical Accelerator in Chiba (HIMAC) using an optimized target of polyethylene. But the purity of the produced beams was around 75%, which is not satisfactory for clinical utilization. Therefore in this study we focused on improvement of the purity of the produced beam by adding a wedge-shaped degrader within the beam line. We inserted an aluminum degrader with the thickness of 1.76 cm into the secondary beam line. The purity of the produced beam for the polyethylene target with thicknesses of 5 cm and 11 cm were measured. The in-beam PET images of the produced beams with and without the aluminum degrader in the beam line were obtained using our whole-body dual-ring OpenPET system. The purity of the beam produced by inserting the degrader into the beam line was increased from 75% to 97%.
Investigating Catalyst-Electrolyte Interface By Microelectrode, Infrared Reflection Adsorption Spectroscopy and Neutron Reflectometry (2016)

Understanding of the catalyst-ionomer interfacial behavior is critically important for fuel cell research. In fact, alkaline membrane fuel cells (AMFCs) have shown limited performance compared to proton exchange membrane fuel cells due to relatively poor hydrogen oxidation reaction (HOR) kinetics [1]. Previous work has shown that cationic adsorption at the surface of the catalyst was closely related to the HOR activity [2, 3]. Here, we present the results of a study of the benzyltrimethyl ammonium electrolyte-Pt interface in hydrogen oxidation reaction (HOR). More specifically, we will discuss the adsorption of the cationic group that may inhibit the HOR activity of Pt electrocatalysts. Microelectrode, Infrared Reflection Adsorption Spectroscopy (IRRAS) and Neutron Reflectometry are complementary tools to investigate the catalyst-ionomer interface.

Contact Mechanics of Nanoparticles: Pulling Rigid Nanoparticles from Soft, Polymeric Surfaces (2015)

Detachment of rigid nanoparticles from soft, gel-like polymeric surfaces is studied by using a combination of the molecular dynamics simulations and theoretical calculations. Simulations show that detachment of nanoparticles from soft surfaces proceeds through a neck formation. Analysis of the simulation results demonstrates that the magnitude of the detachment force f* depends on the nanoparticle radius R(p), shear modulus of substrate G(s), surface tension of substrate γ(s), and work of adhesion W. It is controlled by the balance of the elastic energy, surface energy of the neck, and nanoparticle adhesion energy to a substrate and depends on the dimensionless parameter δ ∝ γ(s)(G(s)R(p))(-1/3)W(-2/3). In the case of small values of the parameter δ ≪ 1, the critical detachment force approaches a critical detachment force calculated by Johnson, Kendall, and Roberts for adhesive contact, f* = 1.5πWR(p). However, in the opposite limit, corresponding to soft substrates, for which δ ≫ 1, the critical detachment force f* ∝ γ(s)(3/2)R(p)(1/2)G(s)(-1/2). All simulation data can be described by a scaling function f* ∝ γ(s)(3/2)R(p)(1/2)G(s)(-1/2)δ(-1.89).
<title>Application Of Laser Fluorimetry To Enzyme-Linked Immunoassay</title> (1981)

An enzyme-linked sandwich immunoassay for insulin is described. Horseradish peroxidase is employed as an enzyme label for antibody, and enzyme activity is measured via the fluorogenic substrate, p-hydroxyphenylacetic acid. The product is detected by excitation of fluorescence with the 325 nm line of a cw helium-cadmium ion laser on-line with reverse phase high performance liquid chromatography. The method requires a total incubation time of 45 minutes, and the limit of insulin detection is 1.1 &mu;U/m&ell; (6.6 pM). This assay is applicable to the analysis of human serum samples.
The Solvent-Inaccessible Cys67 Residue of HLA-B27 Contributes to T Cell Recognition of HLA-B27/Peptide Complexes (2004)

Crystallographic studies have suggested that the cysteine at position 67 (Cys(67)) in the B pocket of the MHC molecule HLA-B*2705 is of importance for peptide binding, and biophysical studies have documented altered thermodynamic stability of the molecule when Cys(67) was mutated to serine (Ser(67)). In this study, we used HLA-B27.Cys(67) and HLA-B27.Ser(67) tetramers with defined T cell epitopes to determine the contribution of this polymorphic, solvent-inaccessible MHC residue to T cell recognition. We generated these HLA-B27 tetramers using immunodominant viral peptides with high binding affinity to HLA-B27 and cartilage-derived peptides with lower affinity. We demonstrate that the yield of refolding of HLA-B27.Ser(67) molecules was higher than for HLA-B27.Cys(67) molecules and strongly dependent on the affinity of the peptide. T cell recognition did not differ between HLA-B27.Cys(67) and HLA.B27.Ser(67) tetramers for the viral peptides that were investigated. However, an aggrecan peptide-specific T cell line derived from an HLA-B27 transgenic BALB/c mouse bound significantly stronger to the HLA-B27.Cys(67) tetramer than to the HLA-B27.Ser(67) tetramer. Modeling studies of the molecular structure suggest the loss of a SH ... pi hydrogen bond with the Cys-->Ser substitution in the HLA-B27 H chain which reduces the stability of the HLA-B27/peptide complex. These results demonstrate that a solvent-inaccessible residue in the B pocket of HLA-B27 can affect TCR binding in a peptide-dependent fashion.
