Optimized Multipactor-Resistant Wedge-Shaped Waveguide Bandpass Filters (2013)

Wedge-shaped waveguides present a certain advantage with respect to rectangular waveguides regarding their resistance to multipactor discharges. In this paper, the optimal configuration for the wedge geometry is investigated based on theoretical results, on a precise multipactor prediction tool, and on previous experience. In addition, design rules are presented, which allow us to achieve for wedge-shaped filters electrical performances comparable to the ones of rectangular waveguide filters, while at the same time improving the multipactor-free power range. As a proof of concept, two three-pole bandpass filters with equivalent electrical characteristic of 150-MHz bandwidth, centered at 12 GHz (Ku band), and the same <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">$Q$</tex></formula> factor have been designed, manufactured, and tested. The first design is based on conventional rectangular waveguide technology, while the second one has non-parallel broadside walls (wedge-shaped cross section). The multipactor power threshold and RF performance of the filters have been measured in order to validate the improvements achievable employing wedge-shaped resonators.

Odométrie radar par analyse de la distorsion. Applications à la navigation de véhicules terrestres et nautiques (2012)

L’utilisation d’un capteur télémétrique tournant en robotique mobile à haute vitesse implique l’apparition d’une distorsion sur les données collectées. Un tel effet est, dans la majorité des études, ignoré ou considéré comme un bruit et, de ce fait, corrigé en utilisant des capteurs proprioceptifs ou des systèmes de localisation. Dans cet article, la vélocimétrie du véhicule est extraite de la distorsion, sans aucun autre apport que celui fourni par le capteur extéroceptif. Il s’agit d’un radar panoramique FMCW (Frequency Modulated Continuous Wave), appelé K2Pi. Point d’odomètre, de gyromètre ou autre capteur proprioceptif. Les estimations des vitesses angulaires et linéaires du robot sont ensuite utilisées pour construire, sans aucun autre capteur, la trajectoire du véhicule et la carte radar de l’environnement extérieur exploré. Des résultats de localisation et de cartographie avec ce capteur radar, mais facilement extensibles à d’autres capteurs télémétriques tournants, sont présentés pour des véhicules terrestres et nautiques.
Continuous renal replacement therapy in patients with HIV/AIDS (2020)

There is a high incidence of AKI in HIV-infected patients admitted in our ICU. Patients with severe AKI were more prone to be admitted for CRRT and have a consequent poor prognosis.
Multicentre evaluation of an antigen-detection ELISA for the diagnosis of Trypanosoma brucei rhodesiense sleeping sickness. (1992)

The performance of an enzyme-linked immunosorbent assay (antigen ELISA) for the detection, in serum or cerebrospinal fluid, of an invariant trypanosome antigen to diagnose Trypanosoma brucei rhodesiense sleeping sickness was evaluated in four clinical treatment centres. The test, which was carried out in polystyrene test-tubes, was positive in 88 (88.9%) of 99 parasitologically confirmed cases that were tested at the National Institute for Medical Research, Tabora, United Republic of Tanzania; 99 (94.3%) of 105 cases tested at the National Sleeping Sickness Control Programme, Jinja, Uganda; 86 (87.8%) of 98 cases tested at the Uganda Trypanosomiasis Research Organisation, Tororo, Uganda; and 59 (96.7%) of 61 cases tested at the Tropical Diseases Research Centre, Ndola, Zambia. The overall detection rate was 91.5%. There was no cross-reactivity with the agents of the common bacterial, viral, or parasitic diseases prevalent in the areas where the studies were conducted. The only false-positive result involved a blood donor from a trypanosomiasis endemic focus. The test was simple to perform, was read visually, and is therefore a potential tool for diagnosing human African trypanosomiasis.
Chromium Poisoning Effects on Surface Exchange Kinetics of La0.6Sr0.4Co0.2Fe0.8O3−δ (2017)

The presence of Cr has already been reported in literature to cause severe degradation to La<sub>0.6</sub>Sr<sub>0.4</sub>Co<sub>0.2</sub>Fe<sub>0.8</sub>O<sub>3-δ</sub> (LSCF). However, fundamental understanding of Cr effects on the surface exchange kinetics is still lacking. For the first time, in situ gas phase isotopic oxygen exchange was utilized to quantitatively determine Cr effect on oxygen exchange kinetics of LSCF powder as a function of temperature and water vapor. Our investigations revealed that the formation of secondary phases such as SrCrO<sub>4</sub>, Cr<sub>2</sub>O<sub>3</sub>, Cr-Co-Fe-O, and La-Co-Fe-O can affect both the oxygen dissociation step and overall surface exchange. Specifically, Cr-containing secondary phases on the surface not only decrease the active sites for surface reactions but also alter the nearby stoichiometry of the LSCF matrix, thereby limiting surface oxygen transport. In addition, water molecules actively participate in the surface reactions and can further block the active sites.
Controlling Lewis Basicity in Polythioarsenate Fluxes:  Stabilization of KSnAsS5 and K2SnAs2S6. Extended Chains and Slabs Based on Pyramidal β-[AsS4]3- and [AsS3]3- Units (2002)

Two low-dimensional compounds, KSnAsS(5) and K(2)SnAs(2)S(6), were prepared using liquid polythioarsenate salts, and the results differ from those obtained with the well studied thiophosphate flux. KSnAsS(5) crystallizes in the orthorhombic space group Pbam with cell parameters of a = 8.136(2) A, b = 13.784(4) A, c = 7.428(2) A. KSnAsS(5) features the unusual pyramidal species [AsS(2)(S(2))](3-). K(2)SnAs(2)S(6) crystallizes in the trigonal space group P3 macro with cell parameters a = 6.717(5) A, b = 7.204(8) A, gamma = 120 degrees. The compounds were obtained by controlling the Lewis basicity of the K(2)S/As(2)S(3)/S flux. The optical, thermal, and spectroscopic properties of the compounds are reported.
Randomised study of the effects of fluoride and time on in situ remineralisation of acid-softened enamel (2019)

Demographics, outcomes, and risk factors for adverse events associated with primary and revision total hip arthroplasties in the United States. (2010)

We conducted a study to analyze nationally representative data on patient and health care system characteristics and in-hospital outcomes associated with primary and revision total hip arthroplasties in the United States. Between 1990 and 2004, there were an estimated 2,748,187 hospital discharges after total hip arthroplasty. The risk factors we identified for procedure-related complications and in-hospital mortality included revision procedures, increased age, and male sex. Compared with smaller hospital capacity (number of beds), large hospital capacity was associated with a decreased odds ratio for complications but an increased risk for in-hospital mortality. Additional studies are warranted to determine causal relationships.
Information Distribution in Multi-Robot Systems: Utility-Based Evaluation Model (2020)

This work addresses the problem of information distribution in multi-robot systems, with an emphasis on multi-UAV (unmanned aerial vehicle) applications. We present an analytical model that helps evaluate and compare different information distribution schemes in a robotic mission. It serves as a unified framework to represent the usefulness (<i>utility</i>) of each message exchanged by the robots. It can be used either on its own in order to assess the information distribution efficacy or as a building block of solutions aimed at optimizing information distribution. Moreover, we present multiple examples of instantiating the model for specific missions. They illustrate various approaches to defining the utility of different information types. Finally, we introduce a proof of concept showing the applicability of the model in a robotic system by implementing it in Robot Operating System 2 (ROS 2) and performing a simple simulated mission using a network emulator. We believe the introduced model can serve as a basis for further research on generic solutions for assessing or optimizing information distribution.
A Review of Surgical Procedures for Hallux Valgus (1980)

One hundred seventy-two patients who underwent surgical correction of hallux valgus deformity were evaluated. The procedures chosen were: first metatarsal osteotomy in 96, Keller procedure in 42, metatarsophalangeal arthrodesis in 25, and simple bunionectomy in 9. This study allowed the establishment of the following guidelines for surgery. 1) Osteotomy alone yields a satisfactory result in patients under the age of 50 years who have minimal osteoarthritis of the metatarsophalangeal joint. 2) The Keller procedure is suggested in patients over the age of 50 who have significant osteoarthritis. 3) Metatarsophalangeal fusion is suggested in patients under the age of 50 with significant osteoarthritis. 4) Simple bunionectomy revealed poor results in the majority of patients. It should be reserved for the elderly patient with an infected bunion.
Fabrication of 6FDA‐durene polyimide asymmetric hollow fibers for gas separation (2001)

Abstract We have developed defect‐free asymmetric hexafluoro propane diandydride (6FDA) durene polyimide (6FDA‐durene) hollow fibers with a selectivity of 4.2 for O 2 /N 2 and a permeance of 33.1 ×10 −6 cm 3 (STP)/cm 2 ‐s‐cmHg for O 2. These fibers were spun from a high viscosity in situ imidization dope consisting of 14.7% 6FDA‐durene in a NMP solvent and the inherent viscosities (IV) of this 6FDA‐durene polymer was 0.84 dL/g. Low IV dopes cannot produce defect‐free hollow fibers, indicating a 6FDA‐durene spinning dope with a viscosity in the region of chain entanglement seems to be essential to yield hollow fibers with minimum defects. The effects of spinning parameters such as shear rates within a spinneret and bore fluids as well as air gap on gas separation performance were investigated. Experimental data demonstrate that hollow fibers spun with NMP/H 2 O as the bore liquid have higher permeances and selectivities than those spun with glycerol as the bore liquid because the former has a relatively looser inner skin structure than the latter. In addition, the selectivity of hollow fibers spun with NMP/H 2 O as the bore liquid changes moderately with shear rate, while the selectivity of hollow fibers spun with glycerol are less sensitive to the change of shear rate. These distinct behaviors are mainly attributed to the different morphologies generated by different bore fluids. © 2001 John Wiley &amp; Sons, Inc. J Appl Polym Sci 82: 2166–2173, 2001
Plasmonic Silver Nanobelts via Citrate Reduction in the Presence of HCl and their Orientation-Dependent Scattering Properties (2011)

Silver nanobelts were synthesized without any external seeds or templates using a facile hydrothermal route via citrate reduction in the presence of hydrochloric acid. Both H+ and Cl– ions in HCl are important for the generation of nanobelts. The morphology can be controlled by varying the concentration of HCl and citrate. The obtained nanobelts have 3D orientation-dependent optical properties. By tracking the transportation and rotation of the nanobelts in cells or other biosystems, useful information related to the physical or chemical surroundings may be obtained.
A Novel Single-Step Unconditionally Stable Numerical Integration Scheme With Tunable Algorithmic Dissipation (2020)

Abstract A novel single-step time integration method is proposed for general dynamic problems. From linear spectral analysis, the new method with optimal parameters has second-order accuracy, unconditional stability, controllable algorithmic dissipation and zero-order overshoot in displacement and velocity. Comparison of the proposed method with several representative implicit methods shows that the new method has higher accuracy than the single-step generalized-α method, and also than the composite P∞-Bathe method when mild algorithmic dissipation is used. Besides, this method is spectrally identical to the linear two-step method, although being easier to use since it does not need additional start-up procedures. Its numerical properties are assessed through numerical examples, and the new method shows competitive performance for both linear and nonlinear problems.
Real-world efficacy and safety of pembrolizumab in patients with non-small cell lung cancer: a retrospective observational study (2020)

The results of the present study suggest that pembrolizumab seems less effective in the real-life population than in the pivotal clinical trials in patients with NSCLC but remains an effective treatment option for patients with NSCLC. Longer follow-up is needed.

Adiponectin in Cardiovascular Inflammation and Obesity (2011)

Inflammation is widely known to play a key role in the development and progression of cardiovascular diseases. It is becoming increasingly evident that obesity is linked to many proinflammatory and obesity-associated cardiovascular conditions (e.g., metabolic syndrome, acute coronary syndrome, and congestive heart failure). It has been observed that adipokines play an increasingly large role in systemic and local inflammation. Therefore, adipose tissue may have a more important role than previously thought in the pathogenesis of several disease types. This review explores the recently described role of adiponectin as an immunomodulatory factor and how it intersects with the inflammation associated with both cardiovascular and autoimmune pathologies.
EXTENDED ABSTRACT: A Method for Analyzing Textural Changes Within Clastic Environments Utilizing Electrical Borehole Images (2004)

Electrical borehole images have been utilized to evaluate clastic environments for more than 24 years. During this period textural changes have been classified by an interpreter only as visual features. Now verbal descriptions of clastic textures, as seen on images, can be supplanted by a semi-automatic product that captures high-resolution textural information from electrical borehole images. These attributes may then be produced in a clear, usable format. The method employed and illustrated here is known as sandstone textural analysis (STA) evaluation. This method analyzes the total image resistivity spectrum in a 1-inch interval around the bore. An image-sorting index is calculated from the percentile resistivity distribution of the image spectrum. This resistivity spectrum can be divided into a well sorted portion and the fractions that are either more resistive or conductive. The resistivities of these three fractions can then all be calculated. These outputs, sorting-index, fractional resistivities, variability, along with layering measurements and associated open-hole log data can be combined to compute a facies description that captures the textural content of these clastic environments.
Myelin‐Associated Glycoprotein Is the Antigen for a Monoclonal IgM in Polyneuropathy (1982)

Recent studies show that IgM monoclonal antibody from patients with IgM paraproteinemia and peripheral neuropathy reacts with a protein component of human PNS myelin and an analogous component or components of human CNS myelin. We have now demonstrated that the antigen for this antibody is a specific glycoprotein component of myelin, referred to as myelin-associated glycoprotein (MAG). Human PNS and CNS myelin proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis on pore-gradient slabs, and MAG was identified by the immuno-electroblot procedure with rabbit anti-MAG (rat). The identical band(s) were stained by an analogous procedure with patient serum as the first antibody. Human PNS MAG had an apparent molecular weight of 107,000. Human CNS MAG appeared as three bands: 113,000, 107,000, and 92,000. Passage of myelin proteins through a concanavalin A-Sepharose column removed the staining component. Purified patient IgM, added to a lithium diiodosalicylate extract of myelin, immunoprecipitated MAG. This antibody also cross-reacted with MAG from bovine CNS, but not from rabbit, rat, or mouse.

Opportunistic Link Scheduling with QoS Requirements in Wireless Ad Hoc Networks (2007)

We study the link layer scheduling problem in wireless ad hoc networks. In such a network, the communication links compete for the scarce and time-varying wireless channels. Recently, opportunistic scheduling that exploits variation of channel conditions at each link has drawn great attention to improve system performance. Taking advantage of the multiuser diversity and being aware of the potential contention among neighboring transmissions, we formulate the opportunistic scheduling problems with QoS requirements and present the optimal scheduling policies for both single- and multi- hop ad hoc networks. We also proposed COS, a distributed Cooperative and Opportunistic Scheduling algorithm, which realizes the optimal scheduling policies by introducing the cooperation among neighboring transmitters. Simulation results indicate that our implementation achieves higher network throughput and provides better QoS support than existing solutions.
The Ras superfamily of GTPases 1 (1996)

The Ras superfamily of small GTPases comprises a group of molecular switches that regulate an astonishing diversity of cellular functions. A deep understanding of mitogenesis, cytoskeletal organization, vesicle traffic, and nuclear transport now requires the inclusion of the small GTPases as essential components of the molecular machines that drive these processes. The rich complexity of the control mechanisms involved is evidenced by the recent discoveries of GTPase cascades, multiple downstream effectors, and interconnected networks of GTPase-regulated protein kinase cascades. The 1995 FASEB Summer Conference at Snowmass Village, Colorado, on the Ras GTPase superfamily provided testimony to the broad impact that the study of these proteins continues to exert on cell biology.
Synthesis of C-19-chiral steroids. Preparation of (19R); (19S) and (19RS)-3β-hydroxy[19-2H1,19-3H1] androst-5-en-17-ones (1987)

The synthesis of the title compounds by two routes is described. The syntheses were based on the stereoselective reduction of 17,17-ethylenedioxy-3β-methoxy[19-3H] androst-5-en-19-als to (19R)- and (19S)-alcoho of high diastereoisomeric purities. The alcohols were converted, with retention, into the 19-iodides without loss of diastereoisomeric purity. The iodides were then hydrogenolysed, with inversion, to 19-chiral products.
Recurrent laryngeal nerve paralysis in patients receiving vincristine and vinblastine. (1977)

Three patients receiving vincristine or binblastine developed recurrent laryngeal nerve paralysis, which resolved when the drug was withdrawn. The presence of mediastinal lymphadenopathy in patients with lymphoma may obscure the correct diagnosis, with the danger that the condition will produce respiratory distress if vinca alkaloid treatment is continued.
Relaxin Counteracts Asthma-Like Reaction Induced by Inhaled Antigen in Sensitized Guinea Pigs* (1997)

In previous studies, the peptide hormone relaxin (RLX) was found to inhibit mast cell secretion and platelet activation. It has been established that the release of mediators from these cells plays a central pathogenic role in allergic asthma. This prompted us to ascertain whether RLX may counteract the respiratory and histopathological abnormalities of the asthma-like reaction to inhaled antigen in sensitized guinea pigs. Guinea pigs were sensitized with ovalbumin and challenged with the same antigen given by aerosol. Some animals received RLX (30 microg/kg BW, twice daily for 4 days) before antigen challenge. Other animals received inactivated RLX in place of authentic RLX. Respiratory abnormalities, such as cough and dyspnea, were analyzed as were light and electron microscopic features of lung specimens. RLX was shown to reduce the severity of respiratory abnormalities, as well as histological alterations, mast cell degranulation, and leukocyte infiltration in sensitized guinea pigs exposed to ovalbumin aerosol. RLX was also found to promote dilation of alveolar blood capillaries and to reduce the thickness of the air-blood barrier. This study provides evidence for an antiasthmatic property of RLX and raises the possibility of new therapeutic strategies for allergic asthma in humans.
Low Leakage Current GaN MIS-HEMT with SiNx Gate Insulator using N2 Plasma Treatment (2013)

In this work, an effective N 2 plasma treatment for suppressing leakage current in GaN MIS-HEMT has been demonstrated. We observed an important issue of leakage current from the SiN x /GaN interface. To investigate the leakage current mechanisms, we measured the leakage current from all the possible paths in the device structure, such as gate, mesa isolation, and drain leakage. The current−voltage measurement results reveal a severe leakage path at the SiN x /GaN interface after SiN x deposited on the GaN surface without N 2 plasma treatment. By using N 2 plasma treatment, we succeed in suppressing the leakage current and effectively improve breakdown voltage. A significant performance improvement of GaN MIS-HEMTs with very low leakage current has been achieved through the N 2 plasma treatment.
