Analysis of electromechanical problems using the dual-primal finite element tearing and interconnecting method (2012)

The dual-primal finite element tearing and interconnecting (FETI-DP) method is combined with the tree-cotree splitting (TCS) method to expand the capability and improve the efficiency of the finite-element analysis of electromechanical devices. With the FETI-DP method, an original large-scale problem is decomposed into smaller subdomain problems and parallel computing schemes are then employed to reduce the computation time significantly. The TCS method is adopted to deal with the low-frequency breakdown problem, which often accompanies the finite-element analysis of electromechanical problems. The proposed technique is applied to solve a multi-connected eddy-current problem and compute force for a magnetostatic problem. The results show that the proposed method can achieve an excellent accuracy and a good parallel efficiency.
An Investigation of the Effect of Inclination on Critical Heat Flux of PF-5060 Dielectric Liquid on Microporous Copper Surfaces (2013)

Pool boiling experiments investigated the effect of inclination angle on the Critical Heat Flux (CHF) for saturation boiling of PF-5060 dielectric liquid on MicroPorous Copper (MPC) surfaces of different thicknesses (80 to 230 μm). The morphology of the surfaces, deposited using electrochemical processes, vary with the thickness, and hence CHF. The inclination angles investigated are 0° (upward facing), 60°, 90° (vertical), 120°, 150°, 160°, 170° and 180° (downward facing). CHF decreases with decreasing MPC thickness and/or increasing inclination angle. The CHF values in the upward facing orientation are 39%–67% higher than on smooth, polished Cu. For all MPC surfaces, CHF values in the downward facing orientation are ∼ 28% of those in the upward facing orientation (0°). The developed CHF correlation accounts for the effects of MPC thickness and inclination angle and is in agreement with experimental data to within ± 8%.
Effects of the partial removal of wood hemicelluloses on the properties of kraft pulp (2014)

The objective of this work was to study the effects of partial removal of wood hemicelluloses&#13;\non the properties of kraft pulp.The work was conducted by extracting hemicelluloses (1) by a&#13;\nsoftwood chip pretreatment process prior to kraft pulping, (2) by alkaline extraction from&#13;\nbleached birch kraft pulp, and (3) by enzymatic treatment, xylanase treatment in particular, of&#13;\nbleached birch kraft pulp. The qualitative and quantitative changes in fibers and paper&#13;\nproperties were evaluated. In addition, the applicability of the extraction concepts and&#13;\nhemicellulose-extracted birch kraft pulp as a raw material in papermaking was evaluated in a&#13;\npilot-scale papermaking environment. The results showed that each examined hemicellulose&#13;\nextraction method has its characteristic effects on fiber properties, seen as differences in both&#13;\nthe physical and chemical nature of the fibers.&#13;\nA prehydrolysis process prior to the kraft pulping process offered reductions in cooking time,&#13;\nbleaching chemical consumption and produced fibers with low hemicellulose content that are&#13;\nmore susceptible to mechanically induced damages and dislocations. Softwood chip&#13;\npretreatment for hemicellulose recovery prior to cooking, whether acidic or alkaline, had an&#13;\nimpact on the physical properties of the non-refined and refined pulp. In addition, all the&#13;\npretreated pulps exhibited slower beating response than the unhydrolyzed reference pulp.&#13;\nBoth alkaline extraction and enzymatic (xylanase) treatment of bleached birch kraft pulp&#13;\nfibers indicated very selective hemicellulose removal, particularly xylan removal.&#13;\nFurthermore, these two hemicellulose-extracted birch kraft pulps were utilized in a pilot-scale&#13;\npapermaking environment in order to evaluate the upscalability of the extraction concepts.&#13;\nInvestigations made using pilot paper machine trials revealed that some amount of alkalineextracted&#13;\nbirch kraft pulp, with a 24.9% reduction in the total amount of xylan, could be used&#13;\nin the papermaking stock as a mixture with non-extracted pulp when producing 75 g/m2&#13;\npaper. For xylanase-treated fibers there were no reductions in the mechanical properties of the&#13;\n180 g/m2 paper produced compared to paper made from the control pulp, although there was a&#13;\n14.2% reduction in the total amount of xylan in the xylanase-treated pulp compared to the&#13;\ncontrol birch kraft pulp.&#13;\nThis work emphasized the importance of the hemicellulose extraction method in providing&#13;\nnew solutions to create functional fibers and in providing a valuable hemicellulose co-product&#13;\nstream. The hemicellulose removal concept therefore plays an important role in the integrated&#13;\nforest biorefinery scenario, where the target is to the co-production of hemicellulose-extracted&#13;\npulp and hemicellulose-based chemicals or fuels.

Sources, Derivation, and Culture of Human Embryonic Stem Cells (2006)

Human embryonic stem cells (hESCs) are immortal cells capable of perpetual self-renewal in culture while maintaining their undifferentiated state, high telomerase activity, normal karyotype, and specific pattern expression of embryonic surface markers and pluripotent transcription factors such as Oct-4 and Nanog. Since their first derivation in 1998, hundreds of hESC lines have been derived and characterized. Normal surplus embryos from IVF programs are the main source for the derivation of hESC lines but cell lines from poor-quality discarded embryos or embryos carrying genetic defects following preimplantation genetic diagnosis were also isolated. Such isolation is usually accomplished by either mechanical or immunosurgical removal of the trophectoderm and culture of the inner cell mass on inactivated feeder cells. In light of the future need for clinical-grade cells, the subject of defining specific culture conditions has been addressed widely. Indeed, derivation and maintenance of hESCs without feeder cells and in media free of animal products have been attained recently. This well-defined culture system may facilitate research and clinical applications, and use the remarkable potential of these exceptional cells to its fullest in both the laboratory and the clinic.
Reconfigurable Intelligent Surfaces for Smart Cities: Research Challenges and Opportunities (2020)

The concept of Smart Cities has been introduced as a way to benefit from the digitization of various ecosystems at a city level. To support this concept, future communication networks need to be carefully designed with respect to the city infrastructure and utilization of resources. Recently, the idea of ‘smart’ environment, which takes advantage of the infrastructure in order to enable better performance of wireless networks, has been proposed. This idea is aligned with the recent advances in design of reconfigurable intelligent surfaces (RISs), which are planar structures with the capability to reflect impinging electromagnetic waves toward preferred directions. Thus, RISs are expected to provide the necessary flexibility for the design of the ‘smart’ communication environment, which can be optimally shaped to enable cost- and energy-efficient signal transmissions where needed. Upon deployment of RISs, the ecosystem of the Smart Cities would become even more controllable and adaptable, which would subsequently ease the implementation of future communication networks in urban areas and boost the interconnection among private households and public services. In this article, we provide our vision on RIS integration into future Smart Cities by pointing out some forward-looking new application scenarios and use cases and by highlighting the potential advantages of RIS deployment. To this end, we identify the most promising research directions and opportunities. The respective design problems are formulated mathematically. Moreover, we focus the discussion on the key enabling aspects for RIS-assisted Smart Cities, which require substantial research efforts such as pilot decontamination, precoding for large multiuser networks, distributed operation and control of RISs. These contributions pave the road to a systematic design of RIS-assisted communication networks for Smart Cities in the years to come.
Efficient Semitransparent CsPbI3 Quantum Dots Photovoltaics Using a Graphene Electrode (2019)

Abstract Solution‐processed perovskite quantum dots (QDs) are promising candidates for fabrication of semitransparent and tandem solar cells due to the bandgap tunability. In this work, cesium lead triiodide (CsPbI 3 ) QDs are synthesized with a stable cubic phase and efficient perovskite solar cells (PSCs) are fabricated using the ligand exchange technique. Monolayer graphene is grown by chemical vapor deposition technique and a dry process to transfer graphene on top of the device is developed. Based on this approach, an efficient inverted PSC is demonstrated with a high average visible transmittance (AVT). After optimization, PSCs based on silver and graphene electrodes with power conversion efficiencies (PCEs) of 9.6% and 6.8% are achieved, respectively. Additionally, by tuning the thickness of the active layer, a PSC with PCE of 4.95% and AVT of 53% is demonstrated, indicating the potential of CsPbI 3 QDs for the fabrication of semitransparent devices applicable in windows.

The impact of viral mutations on recognition by SARS-CoV-2 specific T cells (2021)

We identify amino acid variants within dominant SARS-CoV-2 T cell epitopes by interrogating global sequence data. Several variants within nucleocapsid and ORF3a epitopes have arisen independently in multiple lineages and result in loss of recognition by epitope-specific T cells assessed by IFN-γ and cytotoxic killing assays. Complete loss of T cell responsiveness was seen due to Q213K in the A∗01:01-restricted CD8+ ORF3a epitope FTSDYYQLY<sub>207-215</sub>; due to P13L, P13S, and P13T in the B∗27:05-restricted CD8+ nucleocapsid epitope QRNAPRITF<sub>9-17</sub>; and due to T362I and P365S in the A∗03:01/A∗11:01-restricted CD8+ nucleocapsid epitope KTFPPTEPK<sub>361-369</sub>. CD8+ T cell lines unable to recognize variant epitopes have diverse T cell receptor repertoires. These data demonstrate the potential for T cell evasion and highlight the need for ongoing surveillance for variants capable of escaping T cell as well as humoral immunity.
Integrated Dynamic Thermo-Mechanical Modeling of High Speed Spindles, Part 2: Solution Procedure and Validations (2004)

This paper presents a new solution procedure for an integrated thermo-dynamic spindle model and validation results. Based on the model presented in Part 1 of this paper, a computer program has been developed to generate comprehensive solutions for high speed spindle-bearing systems, such as bearing stiffness, contact load and temperature, spindle dynamic characteristics and response, temperature distributions, and thermal expansions. The model and the solution procedure are modular such that solutions for different spindle set-ups can be easily generated by combining a given spindle model with different toolholder models. Validation test results for thermal and dynamic predictions are presented for four different spindle systems, including the thermal and dynamic validation tests on a specially constructed spindle testbed. The validation results show the model has accurate predictive capabilities for a wide range of operating conditions and various spindle designs.
A Multi-centre, General Practice Comparison of Ispaghula Husk with Lactulose and Other Laxatives in the Treatment of Simple Constipation (1998)

An open, multi-centre study in general practice compared with efficacy, speed of action and acceptability of ispaghula husk (Fybogel Orange, Reckitt & Colman Products, UK), lactulose and other laxatives in the treatment of patients with simple constipation. A total of 65 GPs recruited 394 patients, of whom 224 (56.9%) were assigned to treatment with ispaghula and 170 (43.1%) to other laxatives (mainly lactulose) for up to four weeks. Thirteen patients withdrew before treatment started, so that 381 entered the study. Patients were assessed by their GP before entry and after two and four weeks of treatment. Patients also kept daily records of their bowel movements. After four weeks' treatment, ispaghula husk was assessed by the GPs to be superior to the other treatments in improving bowel function and in overall effectiveness, palatability and acceptability. Patients' reports of time to first bowel movement showed little difference between the treatments. Over 60% of patients in each treatment group passed a first motion within 24 hours, and over 80% within 36 hours. Ispaghula husk produced a higher percentage of normal, well-formed stools and fewer hard stools than other laxatives. Incidences of soiling, diarrhoea and abdominal pain were lower in the group receiving ispaghula husk. Overall, ispaghula husk was an effective treatment for simple constipation, and was associated with better stool consistency and a lower incidence of adverse events compared with lactulose or with other laxatives.
Correction: Coherent Superposition in Grating-Based Directional Dark-Field Imaging (2013)

X-ray dark-field scatter imaging allows to gain information on the average local direction and anisotropy of micro-structural features in a sample well below the actual detector resolution. For thin samples the morphological interpretation of the signal is straight forward, provided that only one average orientation of sub-pixel features is present in the specimen. For thick samples, however, where the x-ray beam may pass structures of many different orientations and dimensions, this simple assumption in general does not hold and a quantitative description of the resulting directional dark-field signal is required to draw deductions on the morphology. Here we present a description of the signal formation for thick samples with many overlying structures and show its validity in experiment. In contrast to existing experimental work this description follows from theoretical predictions of a numerical study using a Fourier optics approach. One can easily extend this description and perform a quantitative structural analysis of clinical or materials science samples with directional darkfield imaging or even direction-dependent dark-field CT.

The uniqueness of the capacity-achieving distribution over non-coherent flat-fading channels (2004)

We prove the uniqueness of the capacity-achieving input distribution for a noncoherent flat-fading channel (Rayleigh or Rician), subject to a second moment constraint. For this purpose, we first show the uniqueness and symmetry of the capacity-achieving output distribution. Then, we establish the assertion by proving that every fading channel is a bijective mapping from the space of symmetric, input distributions to the induced space of symmetric output distributions. This proof is constructive in the sense that for a given symmetric output distribution, one can uniquely determine the input distribution that induced such an output distribution.
Stream Classification with Recurring and Novel Class Detection Using Class-Based Ensemble (2012)

Concept-evolution has recently received a lot of attention in the context of mining data streams. Concept-evolution occurs when a new class evolves in the stream. Although many recent studies address this issue, most of them do not consider the scenario of recurring classes in the stream. A class is called recurring if it appears in the stream, disappears for a while, and then reappears again. Existing data stream classification techniques either misclassify the recurring class instances as another class, or falsely identify the recurring classes as novel. This increases the prediction error of the classifiers, and in some cases causes unnecessary waste in memory and computational resources. In this paper we address the recurring class issue by proposing a novel "class-based" ensemble technique, which substitutes the traditional "chunk-based" ensemble approaches and correctly distinguishes between a recurring class and a novel one. We analytically and experimentally confirm the superiority of our method over state-of-the-art techniques.
Self-consistent electro-thermal simulation of AlGaN/GaN HEMTs for reliability prediction (2010)

In this paper, we have developed the first fully-coupled electro-thermo-mechanical simulation of AIGaN/GaN HEMTs to study the reliability of these devices as a function of bias voltage and operating temperature. In addition, we have compared the numerical results of our simulations with high resolution thermo-reflectance measurements, obtaining excellent agreement.
Phenyldiazenyl benzothiazole derivatives as probes for in vivo imaging of neurofibrillary tangles in Alzheimer's disease brains (2011)

This paper describes the synthesis and biological evaluation of novel phenyldiazenyl benzothiazole (PDB) derivatives as probes for imaging neurofibrillary tangles (NFTs) in patients with Alzheimer's disease (AD). We successfully synthesized three PDB derivatives using a diazo coupling reaction. In binding experiments in vitro, the compounds displayed higher affinity for tau aggregates than for Aβ aggregates. In fluorescent staining experiments using AD brain sections, 9 visualized NFTs clearly. No-carrier-added radioiodinated PDB derivatives were successfully prepared through an iododestannylation reaction from the corresponding tributyltin derivatives. [125I]9 labeled NFTs in sections of brain tissue from a patient with AD, but not a control. In biodistribution experiments using normal mice, the PDB derivatives displayed an uptake into the brain, sufficient for imaging NFTs, ranging from 0.94 to 3.2% ID g−1, but a relatively slow washout. Although further modifications are necessary to improve the pharmacokinetics in the brain, PDB with high affinity for tau aggregates may be useful as a backbone structure to develop agents for imaging NFTs in AD brains.

Reducing Channel Interaction Through Cochlear Implant Programming May Improve Speech Perception (2016)

Speech perception among cochlear implant (CI) listeners is highly variable. High degrees of channel interaction are associated with poorer speech understanding. Two methods for reducing channel interaction, focusing electrical fields, and deactivating subsets of channels were assessed by the change in vowel and consonant identification scores with different program settings. The main hypotheses were that (a) focused stimulation will improve phoneme recognition and (b) speech perception will improve when channels with high thresholds are deactivated. To select high-threshold channels for deactivation, subjects' threshold profiles were processed to enhance the peaks and troughs, and then an exclusion or inclusion criterion based on the mean and standard deviation was used. Low-threshold channels were selected manually and matched in number and apex-to-base distribution. Nine ears in eight adult CI listeners with Advanced Bionics HiRes90k devices were tested with six experimental programs. Two, all-channel programs, (a) 14-channel partial tripolar (pTP) and (b) 14-channel monopolar (MP), and four variable-channel programs, derived from these two base programs, (c) pTP with high- and (d) low-threshold channels deactivated, and (e) MP with high- and (f) low-threshold channels deactivated, were created. Across subjects, performance was similar with pTP and MP programs. However, poorer performing subjects (scoring < 62% correct on vowel identification) tended to perform better with the all-channel pTP than with the MP program (1 > 2). These same subjects showed slightly more benefit with the reduced channel MP programs (5 and 6). Subjective ratings were consistent with performance. These finding suggest that reducing channel interaction may benefit poorer performing CI listeners.
Feedback Amplifier based on an Embedded HEMT in Thin-film Multilayer MCM-D Technology (2003)

In this paper a feedback amplifier circuit integrated in MCM-D (MultiChip Module with Deposited thin films) on glass technology is presented. The active device of the amplifier is a thin-film Ge (germanium) -based HEMT. The HEMT is embedded in the bottom dielectric layer of the MCM-D. The combination of passive MCM-D technology and HEMTs on Ge allows for efficient semimonolithic integration of active devices and realization of MCMs with embedded passive and active components for amplifier circuits.
