Search for new particles in hadronic events with isolated photons (1996)

A search for the neutral Higgs boson in the processes e+e− → Z → H0γ → qqγ and e+e− → Z → Z∗H0 → qqγγ has been performed using 2.8 million hadronic Z decays collected with the L3 detector at LEP from 1991 through 1994. No evidence for these processes has been observed. Upper limits at 95% confidence level for the corresponding cross sections have been set and the results have been compared with theoretical predictions beyond the Standard Model.
Immunologically active zones in bovine growth hormone (1979)

Antigenic determinant areas were detected in bovine growth hormone fragments 6--124 and 125--149, the former being predominant. Reduction and carboxymethylation of disulfide bridge 53--164 destroys the immunological reactivity of the area which is little affected by reduction and carbamoylmethylation. All the activity found in fragment 6--124 seems to be concentrated in the sequence 87--124.
Substrate removal of AlGaN/GaN HEMTs using laser lift‐off (2005)

AlGaN/GaN high electron mobility transistors are very promising for microwave power applications. Integration and packaging of those high power density devices requires specific attention to thermal management, especially when the AlGaN/GaN heterostructures are grown on sapphire substrates. Indeed, the low thermal conductivity of sapphire is limiting the power performance of the devices. To improve the thermal management, we propose to remove the sapphire substrate after the HEMT processing. In this paper we show that the sapphire substrate can be removed using laser lift-off, without any substantial degradation of the HEMT properties. This is a first important step towards a system-in-a-package integration of AlGaN/GaN HEMTs for RF power applications. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
License-Assisted Access Considerations (2017)

With mobility as the dominant theme in the emerging fabric of IoE (Internet of Everything), a prolific demand for capacity is a natural consequence. Throughput, latency reduction, availability and reliability are elemental attributes of experientially attractive and robust mobile multimedia services. These elemental attributes drive the demand for spectrum. The use of E-UTRA (Enhanced-Universal Terrestrial Radio Access) technologies, specified under the LTE project, over the 5 GHz unlicensed spectrum, is being considered as a forward-looking approach for standardization to meet the growing capacity demands to support mobile multimedia services. The 5 GHz spectrum band also includes the ISM (Industrial, Scientific, and Medical) band, which is utilized by the IEEE 802 family of technologies. LAA (license assisted access) refers to the use of LTE technologies over unlicensed spectrum, with assistance using a licensed radio frequency carrier. A significant challenge in the standardization of LAA for interoperability is the management of co-channel and adjacent channel interference, when both E-UTRA and the IEEE family of technologies share the same unlicensed spectrum. These challenges are compounded by the differences in the regulations across the three different global ITU (International Telecommunication Union) regions (Europe, Americas, and Asia.) This article will identify strategies and corresponding trade-offs to mitigate the coexistence challenges between the E-UTRA and the IEEE family of technologies, utilizing forward-looking and interoperable enablers. In conclusion, the article will delineate recommendations for a realization of CA (carrier aggregation) between licensed and unlicensed spectrum for downlink and uplink, to accomplish deployment-specific capacity enhancements.
RF source-seeking by a micro aerial vehicle using rotation-based angle of arrival estimates (2013)

We investigate a computationally and memory efficient algorithm for radio frequency (RF) source-seeking with a single-wing rotating micro aerial vehicle (MAV) equipped with a directional antenna. The MAV is assumed to have no knowledge of its position and to have only an estimate of orientation through a magnetometer. A key novelty of our approach is in exploiting the rotation of the MAV and the directionality of its RF antenna to derive estimates of the angle of arrival (AOA) at each rotation. The MAV then follows the estimated direction until the next rotation is complete. We prove convergence of this greedy algorithm under rather weak assumptions on the noise associated with the AOA estimates, using recent results on the property of recurrence for systems governed by stochastic difference inclusions. These convergence results are supplemented by simulations quantifying the amount of excess travel, relative to the straight line distance to the source. Indoor experiments using Lockheed Martin's Samarai MAV demonstrate the efficacy of the greedy algorithm both for static source-seeking, and for the more challenging problem of tracking a moving source.
2D-supramolecular arrangements of dibenzo-18-crown-6-ether and its inclusion complex with potassium ion by potential controlled adsorption (2002)

The construction of self-organized adlayers of dibenzo-18-crown-6 and its inclusion complex with potassium ion on a Au(111) surface was independently achieved by potential-controlled adsorption. Highly-ordered adlayers both for the metal-free state and the complex were visualized by in-situ STM with sub-molecular visualization. The potassium ions in the complex were also clearly visualized.
On the performance of filter bank based multicarrier systems in xDSL and WLAN applications (2002)

We consider filter bank based multicarrier systems which have been considered for fast digital subscriber line applications and possibly could be interesting also for broadband wireless LAN applications. In addition to being resistant to narrowband interference, these systems provide better spectral shaping than DFT-based OFDM and DMT systems for the subchannels, as well as for the overall signal. Furthermore, they provide better efficiency because the time-domain guard interval is not needed and the guard-band in frequency domain can be reduced. The channel equalization for such systems has been an open problem, but the paper demonstrates that it can be solved, at least in principle, even though effective adaptive equalization algorithms are still under development. Another open question is the performance when nonlinearities are included in the chain, especially in the transmitter power amplifier. In the paper, it is demonstrated that the performance of filter bank based systems with nonlinear power amplifiers is only slightly worse than in the corresponding OFDM/DMT systems. When the number of channels is the same, no more than 1 dB higher input backoff is required.

Intent-based cognitive closed-loop management with built-in conflict handling (2022)

The ever-growing complexity in networks and the various future use cases with diverse, and often stringent performance requirements call for a higher level of automation. A tool to achieve this higher level of automation is intent-based management, where the human operator only communicates via high-level intents with the network. Intents are declarative in nature, they specify the desired state but don’t specify how to achieve it. The system will assure that the intents are fulfilled, by monitoring the behavior of the network, and adjusting its configurations if needed. In future networks that will serve multiple tenants and use cases at the same time, many intents will co-exist. As the resources are limited, conflicts may arise between intents. Therefore, a solution is needed for conflict detection and resolution. In this paper, we present a system that is capable of handling multiple intents and detecting and resolving conflicts at run-time. To show the feasibility, we implement our approach in an end-to-end prototype.
Definition of a fluorescence in-situ hybridization score identifies high- and low-level FGFR1 amplification types in squamous cell lung cancer (2012)

We recently reported fibroblast growth factor receptor-type 1 (FGFR1) amplification to be associated with therapeutically tractable FGFR1 dependency in squamous cell lung cancer. This makes FGFR1 a novel target for directed therapy in these tumors. To reproducibly identify patients for clinical studies, we developed a standardized reading and evaluation strategy for FGFR1 fluorescence in-situ hybridization (FISH) and propose evaluation criteria, describe different patterns of low- and high-level amplifications and report on the prevalence of FGFR1 amplifications in pulmonary carcinomas. A total of 420 lung cancer patients including 307 squamous carcinomas, 100 adenocarcinomas of the lung and 13 carcinomas of other types were analyzed for FGFR1 amplification using a dual color FISH. We found heterogeneous and different patterns of gene copy numbers. FGFR1 amplifications were observed in 20% of pulmonary squamous carcinomas but not in adenocarcinomas. High-level amplification (as defined by an FGFR1/centromer 8 (CEN8) ratio ≥2.0, or average number of FGFR1 signals per tumor cell nucleus ≥6, or the percentage of tumor cells containing ≥15 FGFR1 signals or large clusters ≥10%) was detected at a frequency of 16% and low-level amplification (as defined by ≥5 FGFR1 signals in ≥50% of tumor cells) at a frequency of 4%. We conclude that FGFR1 amplification is one of the most frequent therapeutically tractable genetic lesions in pulmonary carcinomas. Standardized reporting of FGFR1 amplification in squamous carcinomas of the lung will become increasingly important to correlate therapeutic responses with FGFR1 inhibitors in clinical studies. Thus, our reading and evaluation strategy might serve as a basis for identifying patients for ongoing and upcoming clinical trials.
Morphological changes induced by addition of polystyrene onto dextran-b-polystyrene block copolymer solutions (2020)

We discuss the effect of adding various amounts in solution of a linear PS standard of Mn = 25,000 g/mol onto a pre-formed nanostructure obtained by self-assembly of dextran40-block-polystyrene270 (dex40-b-PS270). Since there is no common solvent for such a hybrid except mixtures of tetrahydrofuran and dimethylsulfoxide for high PS content, the self assembly is investigated by means of dynamic and static light scattering from dilute solutions of blends using such mixtures. By so dramatically and artificially increasing the hydrophobic mass fraction, the resulting blends exhibit solution properties which depend on the amount of the added PS. It is demonstrated that the dex40-b-PS270 block copolymer can tolerate quite large amounts of the PS additive giving rise, as expected, to a morphological transition when compared to the parent nanostructures, while higher amounts of the PS additive lead to the precipitation of the blends. Interestingly, blend of a given composition exhibits the same vesicular morphology as in the case of the dex40-b-PS775 copolymer of the same composition, that is, free of any PS additive.
The IDAES process modeling framework and model library—Flexibility for process simulation and optimization (2021)

Abstract Energy systems and manufacturing processes of the 21st century are becoming increasingly dynamic and interconnected, which require new capabilities to effectively model and optimize their design and operations. Such next generation computational tools must leverage state‐of‐the‐art techniques in optimization and be able to rapidly incorporate new advances. To address these requirements, we have developed the Institute for the Design of Advanced Energy Systems (IDAES) Integrated Platform, which builds on the strengths of both process simulators (model libraries) and algebraic modeling languages (advanced solvers). This paper specifically presents the IDAES Core Modeling Framework (IDAES‐CMF), along with a case study demonstrating the application of the framework to solve process optimization problems. Capabilities provided by this framework include a flexible, modifiable, open‐source platform for optimization of process flowsheets utilizing state‐of‐the‐art solvers and solution techniques, fully open and extensible libraries of dynamic unit operations models and thermophysical property models, and integrated support for superstructure‐based conceptual design and optimization under uncertainty.
Combination Adenovirus and Protein Vaccines Prevent Infection or Reduce Viral Burden after Heterologous Clade C Simian-Human Immunodeficiency Virus Mucosal Challenge (2017)

HIV vaccine development is focused on designing immunogens and delivery methods that elicit protective immunity. We evaluated a combination of adenovirus (Ad) vectors expressing HIV 1086.C (clade C) envelope glycoprotein (Env), SIV Gag p55, and human pegivirus GBV-C E2 glycoprotein. We compared replicating simian (SAd7) with nonreplicating human (Ad4) adenovirus-vectored vaccines paired with recombinant proteins in a novel prime-boost regimen in rhesus macaques, with the goal of eliciting protective immunity against SHIV challenge. In both vaccine groups, plasma and buccal Env-specific IgG, tier 1 heterologous neutralizing antibodies, and antibody-dependent cell-mediated viral inhibition were readily generated. High Env-specific T cell responses elicited in all vaccinees were significantly greater than responses targeting Gag. After three intrarectal exposures to heterologous tier 1 clade C SHIV, all 10 sham-vaccinated controls were infected, whereas 4/10 SAd7- and 3/10 Ad4-vaccinated macaques remained uninfected or maintained tightly controlled plasma viremia. Time to infection was significantly delayed in SAd7-vaccinated macaques compared to the controls. Cell-associated and plasma virus levels were significantly lower in each group of vaccinated macaques compared to controls; the lowest plasma viral burden was found in animals vaccinated with the SAd7 vectors, suggesting superior immunity conferred by the replicating simian vectors. Furthermore, higher V1V2-specific binding antibody titers correlated with viral control in the SAd7 vaccine group. Thus, recombinant Ad plus protein vaccines generated humoral and cellular immunity that was effective in either protecting from SHIV acquisition or significantly reducing viremia in animals that became infected, consequently supporting additional development of replicating Ad vectors as HIV vaccines.<b>IMPORTANCE</b> There is a well-acknowledged need for an effective AIDS vaccine that protects against HIV infection and limits <i>in vivo</i> viral replication and associated pathogenesis. Although replicating virus vectors have been advanced as HIV vaccine platforms, there have not been any direct comparisons of the replicating to the nonreplicating format. The present study directly compared the replicating SAd7 to nonreplicating Ad4 vectors in macaques and demonstrated that in the SAd7 vaccine group, the time to infection was significantly delayed compared to the control group, and V1V2 Env-specific binding antibodies correlated with viral outcomes. Viral control was significantly enhanced in vaccinated macaques compared to controls, and in infected SAd7-vaccinated macaques compared to Ad4-vaccinated macaques, suggesting that this vector may have conferred more effective immunity. Because blocking infection is so difficult with current vaccines, development of a vaccine that can limit viremia if infection occurs would be valuable. These data support further development of replicating adenovirus vectors.
Evaluation of Plasma-Deposited Hydrophobic Coatings on Pigment-Coated Paper for Reduced Dampening Water Absorption (2010)

Hydrophobic plasma coatings were deposited on pigment-coated paper with the purpose of reducing dampening water absorption and create uniform surface chemistry. The influence of plasma coatings on sheet-fed offset printability was also studied. Three plasma chemistries, fluorocarbon, organosilicon and hydrocarbon, were used to adjust the hydrophobicity of paper surface. The plasma coatings reduced, and in some cases prevented, the dampening water absorption into pigment-coated paper in both laboratory and pilot scale trials. Ink transfer, mottle and ink setting were altered due to the presence of the plasma coatings, whereas porosity and surface strength of the pigment-coated papers were not affected. These results suggest that the preferred way to improve the print quality with both mineral and linseed oil-based inks is to use plasma chemistry that modifies the paper surface to be both hydrophobic and oleophilic. Hydrophobic and oleophobic surfaces were found to cause ink repellence. Uniformity of the plasma coatings was crucial for obtaining an even print appearance.

Parallel O(N) Stokes’ solver towards scalable Brownian dynamics of hydrodynamically interacting objects in general geometries (2017)

An efficient parallel Stokes' solver has been developed for complete description of hydrodynamic interactions between Brownian particles in bulk and confined geometries. A Langevin description of the particle dynamics is adopted, where the long-range interactions are included using a Green's function formalism. A scalable parallel computational approach is presented, where the general geometry Stokeslet is calculated following a matrix-free algorithm using the general geometry Ewald-like method. Our approach employs a highly efficient iterative finite-element Stokes' solver for the accurate treatment of long-range hydrodynamic interactions in arbitrary confined geometries. A combination of mid-point time integration of the Brownian stochastic differential equation, the parallel Stokes' solver, and a Chebyshev polynomial approximation for the fluctuation-dissipation theorem leads to an O(N) parallel algorithm. We illustrate the new algorithm in the context of the dynamics of confined polymer solutions under equilibrium and non-equilibrium conditions. The method is then extended to treat suspended finite size particles of arbitrary shape in any geometry using an immersed boundary approach.
Optical Cable Design (1984)

Optical cable applications can be divided into four major market segments. These are telecommunication, data, video and military communication. For the majority of the telecommunication, data, and video applications, a loose tube or loose ribbon design can be manufactured without incurring a microbending loss penalty. Fibre performance in the loose tube cables can be maximized by optimizing the lay length, tube dimension and pitch diameter. At present, high quality cables using both single and multimode fibre are being manufactured in volume with no additional microbending loss. For example, single and multimode cables with loss of 0.5 dB/km 1300 nm and very high bandwidths or low dispersion have been successfully installed in many cities. An example of this cable is shown in Figure 1. These cables have been used for direct buried, duct system, aerial or underwater installations.
