HPV Related Squamous Cell Carcinomas of the Head and Neck Metastatic to the Small Bowel: First Case Report and Review of the Literature (2016)

BACKGROUND Human papillomavirus (HPV) related squamous cell carcinomas of the oropharynx (OHPV‐SCC) have become increasingly prevalent in recent years. We report the first case of metastatic OHPV‐SCC to the small bowel and its clinical pathological features, illustrating the nature of this lesion. A review of the literature is included to discuss the current understanding of oropharyngeal HPV‐SCC (OHPV‐SCC), the role of p16 immunostain and HPV detection in these clinical settings. CASE PRESENTATION We report the first proven case of OHPV‐SCC metastatic to the small bowel. The patient is a 68 year‐old male that was originally diagnosed with OHPV‐SCC. He was treated with chemoradiation that resulted in tumor regression. Two years later, he presented with acute neurological symptoms suggestive of a cerebrovascular accident. Computed tomography scan and magnetic resonance imaging showed numerous metastatic lesions that involved multiple organs including the brain, lungs and liver. Imaging also showed an area of small bowel thickening with mesenteric stranding and pneumatosis that was suggestive of perforation. During exploratory surgery, a small bowel perforation was identified and a partial bowel resection was performed. Histopathological examination of the small bowel specimen showed transmural infiltration of a squamous cell carcinoma (). The tumor cells were strongly positive for p16 (), cytokeratin 5/6 and high‐risk HPV chromogenic in situ hybridization, conclusive of a metastatic OHPV‐SCCA. A review of the literature showed prior cases of head and neck SCC metastatic to the small bowel, but none of the cases were identified as HPV related. CONCLUSION We present here the first reported case of OHPV‐SCC metastatic to the small bowel. A review of the literature showed that previous cases of head and neck cancers metastatic to the small bowel have been reported. However, none of these reports was proven to be HPV related. Our case presents immunohistochemical and in situ hybridization features supporting the final diagnosis.
<title>Volumetric imaging system for the ionosphere (VISION)</title> (2002)

The Volumetric Imaging System for the Ionosphere (VISION) is designed to use limb and nadir images to reconstruct the three-dimensional distribution of electrons over a 1000 km wide by 500 km high slab beneath the satellite with 10 km x 10 km x 10 km voxels. The primary goal of the VISION is to map and monitor global and mesoscale (&gt; 10 km) electron density structures, such as the Appleton anomalies and field-aligned irregularity structures. The VISION consists of three UV limb imagers, two UV nadir imagers, a dual frequency Global Positioning System (GPS) receiver, and a coherently emitting three frequency radio beacon. The limb imagers will observe the O II 83.4 nm line (daytime electron density), O I 135.6 nm line (nighttime electron density and daytime O density), and the N<SUB>2</SUB> Lyman-Birge-Hopfield (LBH) bands near 143.0 nm (daytime N<SUB>2</SUB> density). The nadir imagers will observe the O I 135.6 nm line (nighttime electron density and daytime O density) and the N<SUB>2</SUB> LBH bands near 143.0 nm (daytime N<SUB>2</SUB> density). The GPS receiver will monitor the total electron content between the satellite containing the VISION and the GPS constellation. The three frequency radio beacon will be used with ground-based receiver chains to perform computerized radio tomography below the satellite containing the VISION. The measurements made using the two radio frequency instruments will be used to validate the VISION UV measurements.

Hydrophobic Quaternized Poly(fluorene) Ionomers for Emerging Fuel Cells (2022)

Quaternized polymers as ionomeric binders in the electrode enable the operation of alternative fuel cells under high pH conditions or anhydrous conditions to overcome the challenges of the proton exchange membrane fuel cells. Hydrophobicity of the ionomers derived from high fluorine content is beneficial to electrode performance, but due to the synthetic difficulties, not many fluorinated quaternized ionomers have been reported with their influence on electrode behavior in these emerging fuel cells. In this presentation, we report a series of quaternized poly(fluorene)s with controlled hydrophobicity by changing the length of flexible fluoroalkyl chains. The contact angle of the electrodes containing the ionomers ranged from 108.7 to 163.8°, comparable to that of the perfluorosulfonic acid-bonded electrodes. The anion exchange membrane fuel cells employing the ionomer exhibits improved durability (voltage loss 0.41 mV h −1 ) through better water management. The high-temperature proton-exchange membrane fuel cell using the ionomer showed superior H 2 /air performance (1.4 A cm -2 at 0.4 V). The study of the fluorinated poly(fluorene) highlights the benefits of hydrophobic ionomers for highly efficient and cost-effective fuel cell systems.
Correlated electrical breakdown in arrays of high density aligned carbon nanotubes (2011)

We demonstrate that in a densely packed aligned array of single walled carbon nanotubes, the electrical breakdown of one nanotube leads to a highly correlated electrical breakdown of neighboring nanotubes, thereby producing a nanofissure. We show that the origin of the correlation is the electrostatic field of the broken nanotubes that produces locally inhomogeneous current and Joule heating distributions in the neighboring intact nanotubes triggering their breakdowns in the vicinity of the broken nanotubes. Our results suggest that the densely aligned arrays behave like a correlated solid.
Spatial Relational Memory Requires Hippocampal Adult Neurogenesis (2008)

The dentate gyrus of the hippocampus is one of the few regions of the mammalian brain where new neurons are generated throughout adulthood. This adult neurogenesis has been proposed as a novel mechanism that mediates spatial memory. However, data showing a causal relationship between neurogenesis and spatial memory are controversial. Here, we developed an inducible transgenic strategy allowing specific ablation of adult-born hippocampal neurons. This resulted in an impairment of spatial relational memory, which supports a capacity for flexible, inferential memory expression. In contrast, less complex forms of spatial knowledge were unaltered. These findings demonstrate that adult-born neurons are necessary for complex forms of hippocampus-mediated learning.
Low-noise avalanche photodiodes with graded impact-ionization-engineered multiplication region (2001)

A novel impact-ionization-engineered multiplication region for avalanche photodiodes is reported. By pseudograding the multiplication region with materials of different ionization threshold energies, the impact ionization of the injected carrier type is localized, while that of the feedback carrier type is suppressed. Low noise (k/sub eff/<0.1), low dark current, and high gain were achieved.
European Summit on the Prevention and Self-Management of Chronic Respiratory Diseases: report of the European Union Parliament Summit (29 March 2017) (2017)

On March 29, 2017, a European Summit on the Prevention and Self-Management of Chronic Respiratory Diseases (CRD) was organized by the European Forum for Research and Education in Allergy and Airway Diseases. The event took place in the European Parliament of Brussels and was hosted by MEP David Borrelli and MEP Sirpa Pietikainen. The aim of the Summit was to correspond to the needs of the European Commission and of patients suffering from CRD to join forces in Europe for the prevention and self-management. Delegates of the European Rhinologic Society, European Respiratory Society, European Academy of Allergy and Clinical Immunology, European Academy of Paediatrics, and European Patients Organization EFA all lectured on their vision and action plan to join forces in achieving adequate prevention and self-management of CRD in the context of Precision Medicine. Recent data highlight the preventive capacity of education on optimal care pathways for CRD. Self-management and patient empowerment can be achieved by novel educational on-line materials and by novel mobile health tools enabling patients and doctors to monitor and optimally treat CRDs based on the level of control. This report summarizes the contributions of the representatives of different European academic stakeholders in the field of CRD.

Delirium coding rates have shown large increases in the NHS in England and Scotland, likely reflecting several factors including policy initiatives, detection tool implementation and education.
Adenosine A1 receptor promotion of multinucleated giant cell formation by human monocytes: A mechanism for methotrexate-induced nodulosis in rheumatoid arthritis (1997)

Agents that inhibit adenosine A1 receptors might be useful in the treatment of MTX-induced rheumatoid nodulosis, while still potentiating the A2-mediated antiinflammatory effects of MTX on synovitis.
A PFC voltage regulator with low input current distortion derived from a rectifierless topology (2006)

This paper presents an ac–dc converter topology for realization of power factor correction (PFC) voltage regulators for applications where the mains frequency is high and a low input current harmonic is required, e.g., in aircraft power systems. The proposed converter represents a minimal configuration consisting of two basic converters, which can be systematically derived from a previously proposed general synthesis procedure for rectifierless ac–dc converters. The proposed PFC converter has incorporated a control method which drastically reduces the circulating power and hence raises the efficiency to a level comparable to existing PFC converters. The proposed PFC converter can completely eliminate any crossover distortion, which can be significant for supply systems having a high mains frequency. In addition, the proposed converter allows bidirectional energy flow ensuring all inductors work in continuous conduction mode hence eliminating the distortion due to the abrupt change of dynamic response when the operating mode changes. Analysis and design of the power and control circuits will be given and discussed. An experimental system will be presented for verification purposes.
Design of a Wideband Horizontally Polarized Omnidirectional Printed Loop Antenna (2012)

This letter presents the design of a novel wideband horizontally polarized omnidirectional printed loop antenna. The proposed antenna consists of a loop with periodical capacitive loading and a parallel stripline as an impedance transformer. Periodical capacitive loading is realized by adding interlaced coupling lines at the end of each section. Similarly to mu-zero resonance (MZR) antennas, the periodical capacitive loaded loop antenna proposed in this letter allows current along the loop to remain in phase and uniform. Therefore, it can achieve a horizontally polarized omnidirectional pattern in the far field, like a magnetic dipole antenna, even though the perimeter of the loop is comparable to the operating wavelength. Furthermore, the periodical capacitive loading is also useful to achieve a wide impedance bandwidth. A prototype of the proposed periodical capacitive loaded loop antenna is fabricated and measured. It can provide a wide impedance bandwidth of about 800 MHz (2170-2970 MHz, 31.2%) and a horizontally polarized omnidirectional pattern in the azimuth plane.

Comparison of BER measurements in a FFH-OCDMA system with incoherent and coherent sources (2003)

Bit error rate (BER) performance comparison in a FFH-OCDMA system with incoherent and coherent optical sources is performed by using a superfluorescent fiber source as an incoherent source and a single-mode multiwavelength fiber laser as a coherent source. Experimental results show that, the power penalty associated with the beat noise is approximately 1 dB. A measurement of the beat noise RF spectrum, with a matched encoder/decoder pair, is also performed and compared to numerical calculations.
Improving Electrical Breakdown Strength of Polymer Nanocomposites by Tailoring Hybrid-Filler Structure for High-Voltage Dielectric Applications (2018)

In general, dielectric multifiller polymer composites have the potential to achieve enhanced performances by integrating the desirable properties of each filler. However, the improvement in thermophysical and dielectric properties is often accompanied by a deterioration of electrical breakdown strength (EBD). Here, we explore a two-filler polymer nanocomposite structure, based on polyolefins with montmorillonite and calcium carbonate fillers, and present an effective approach to obtain enhanced EBD by tailoring the composite morphology (by designing the pseudo-two-dimensional nanoclays to preferentially physisorb on the surfaces of calcium carbonates, so as to change the nature of the filler/polymer interfaces). It is shown that, in these structured polymer nanocomposites, the breakdown performance is substantially improved, exceeding the performance of the unfilled polymers and of the respective single-filler composites. The enhanced dielectric behavior originates from the specific composite morphology, which capitalizes on the platelet nanofillers to enhance the microfiller/polymer interfaces and on the extended hybrid-filler structure to mitigate low-energy failure initiation and propagation.

A Protein from the Mold Aspergillus giganteus Is a Potent Inhibitor of Fungal Plant Pathogens (2001)

A purified preparation of antifungal protein (AFP) from Aspergillus giganteus exhibited potent antifungal activity against the phytopathogenic fungi Magnaporthe grisea and Fusarium moniliforme, as well as the oomycete pathogen Phytophthora infestans. Under conditions of total inhibition of fungal growth, no toxicity of AFP toward rice protoplasts was observed. Additionally, application of AFP on rice plants completely inhibited M. grisea growth. These results are discussed in relation to the potential of the afp gene to enhance crop protection against fungal pathogens in transgenic plants.
Interaction between Water Molecules and Zinc Sulfide Nanoparticles Studied by Temperature-Programmed Desorption and Molecular Dynamics Simulations (2007)

We have investigated the bonding of water molecules to the surfaces of ZnS nanoparticles (approximately 2-3 nm sphalerite) using temperature-programmed desorption (TPD). The activation energy for water desorption was derived as a function of the surface coverage through kinetic modeling of the experimental TPD curves. The binding energy of water equals the activation energy of desorption if it is assumed that the activation energy for adsorption is nearly zero. Molecular dynamics (MD) simulations of water adsorption on 3 and 5 nm sphalerite nanoparticles provided insights into the adsorption process and water binding at the atomic level. Water binds with the ZnS nanoparticle surface mainly via formation of Zn-O bonds. As compared with bulk ZnS crystals, ZnS nanoparticles can adsorb more water molecules per unit surface area due to the greatly increased curvature, which increases the distance between adjacent adsorbed molecules. Results from both TPD and MD show that the water binding energy increases with decreasing the water surface coverage. We attribute the increase in binding energy with decreasing surface water coverage to the increasing degree of surface under-coordination as removal of water molecules proceeds. MD also suggests that the water binding energy increases with decreasing particle size due to the further distance and hence lower interaction between adsorbed water molecules on highly curved smaller particle surfaces. Results also show that the binding energy, and thus the strength of interaction of water, is highest in isolated nanoparticles, lower in nanoparticle aggregates, and lowest in bulk crystals. Given that water binding is driven by surface energy reduction, we attribute the decreased binding energy for aggregated as compared to isolated particles to the decrease in surface energy that occurs as the result of inter-particle interactions.
A Joint Model for Multimodal Document Quality Assessment (2019)

The quality of a document is affected by various factors, including grammaticality, readability, stylistics, and expertise depth, making the task of document quality assessment a complex one. In this paper, we explore this task in the context of assessing the quality of Wikipedia articles and academic papers. Observing that the visual rendering of a document can capture implicit quality indicators that are not present in the document text --- such as images, font choices, and visual layout --- we propose a joint model that combines the text content with a visual rendering of the document for document quality assessment. Experimental results over two datasets reveal that textual and visual features are complementary, achieving state-of-the-art results.
Photoluminescence in the Earliest Stages of Porous Silicon Formation (1996)

The surface topography of (100) p‐Si surfaces at the early stages of electrochemical etching is examined and correlated with the visible photoluminescence (PL) normally observed from porous silicon. The results from three electrolytes are compared. PL is observed from the silicon with etch times as short as 10 s, well before pores are formed in the silicon. The topographical changes in the silicon surface are consistent with the formation of emitting, constrained surface species (oxyhydrides), however, nanometer size structures are also present which may be associated with the potential for quantum confinement.
High speed page mode sensing scheme for EPROMs and flash EEEPROMs using divided bit line architecture (1990)

A novel high-speed page mode sense scheme for EPROMs and flash EEPROMs has been developed. A divided bit line architecture makes it possible to adopt a folded bit line architecture in which sense amplifiers are located at the end of the bit lines. Dynamic sensing avoids the soft write problem by reducing bit line voltage and the current flow through the memory cell. An experimental 1-Mb flash EEPROM using a 0.6-μm design rule has been designed. Simulated results show that a high-speed address access time of 60 ns and a page mode access time of 15 ns can be achieved
Intergranular corrosion resistance of stainless steel diffusion‐bonded joints with B‐containing amorphous insert metal (1995)

Summary This paper describes an investigation of the intergranular corrosion resistance of austenitic stainless steel joints diffusion‐bonded with an amorphous insert metal containing 1.5 mass% boron, in order to clarify optimum bonding conditions for austenitic stainless steel pipes joined by a high‐speed diffusion bonding system. The sulphuric acid/copper sulphate test is conducted to evaluate the intergranular corrosion of bonded joints caused by a Cr depletion zone. Joints diffusion‐bonded with lower bonding pressure and shorter bonding time are more sensitive to intergranular corrosion. Under such bonding conditions, Cr boride and Cr carboboride precipitates causing selective corrosion are found in the bonding layer. Joints diffusion‐bonded under higher bonding pressure and with longer bonding time, however, show no intergranular corrosion and few precipitates in the bonding layer. With regard to the B‐containing amorphous insert metal used in the present investigation, the optimum bonding conditions for prevention of intergranular corrosion are a bonding temperature of 1473 K, bonding pressure of > 9.8 MPa, and bonding time of > 180 sec.
A Novel Single-Stage Buck–Boost Inverter (2022)

Traditional nonisolated multilevel inverters based on the buck–boost principle usually have some disadvantage such as necessary dead time or capacitor precharging. To overcome these, a new transformerless single-stage buck–boost voltage source inverter topology and its control method are proposed. In addition, the proposed topology has greater advantages in cost and loss. In this letter, the topological characteristics and working mode of the inverter are analyzed, and a modulation scheme that can ensure the balance of the output capacitor voltage is designed. Finally, a hardware experimental prototype is built, and the proposed scheme is experimentally verified based on DSP TMS320F28335 and FPGA XC6SLX9-2TQG144C digital controller.
Introduction: Misfit Moderns (2012)

Ford Madox Ford is a major figure of the modernist age. During a career spanning the five decades that saw the modernist experiment reach its zenith — from the 1890s through to the 1930s — he wrote more than eighty books and is best known as the writer of two exemplary modernist works: The Good Soldier (1915) and the Parade's End tetralogy (1924–28). Ford is also known for his close associations with and unerring support for other innovative and experimental writers amongst his contemporaries. Following their first meeting in 1898, Ford collaborated with Joseph Conrad on two full-length novels and one novella, and during a decade-long friendship the two authors developed a doctrine of literary 'Impressionism'. Ford also founded and edited two groundbreaking periodicals, the English Review in Edwardian London (1908–1910) and the transatlantic review in postwar Paris (1924), in which he published the work of important modernist figures such as Ezra Pound, D. H. Lawrence, Wyndham Lewis, James Joyce, Gertrude Stein, and Ernest Hemingway, among others. However, Ford's is a curious kind of centrality: despite the modernist pedigree of his major novels, many of his lesser-known works do not fulfil the expectations generated by his masterpieces or, indeed, by the category of modernism. Ford, in other words, remains something of a misfit.KeywordsNarrative CoherenceHenry VIIIRussian FormalistNarrative StrategyModernist WritingThese keywords were added by machine and not by the authors.
