BEOL embedded RF-MEMS switch for mm-wave applications (2009)

We demonstrate for the first time the embedded integration of a Radio Frequency Microelectromechanical Systems (RF-MEMS) capacitive switch for mm-wave integrated circuits in a BiCMOS Back-end-of-line (BEOL). The switch shows state-of-the-art performance parameters. The ¿off¿ to ¿on¿ capacitance ratio is 1:10 providing excellent isolation in the mm-wave frequency range. Insertion loss and isolation are found to fall below 1.65 dB and to exceed 15 dB, respectively, in the frequency range of 60 GHz to 110 GHz. Feasibility of switch integration into single chip RF designs is demonstrated for a dual-band voltage controlled oscillator (VCO). No performance degradation was observed after ten billion hot-switching cycles.
The Oxidation Rate of SiC in High Pressure Water Vapor Environments (1999)

CVD SiC and sintered alpha-SiC samples were exposed at 1316 C in a high pressure burner rig at total pressures of 5.7, 15, and 25 atm for times up to 100h. Variations in sample emittance for the first nine hours of exposure were used to determine the thickness of the silica scale as a function of time. After accounting for volatility of silica in water vapor, the parabolic rate constants for Sic in water vapor pressures of 0.7, 1.8 and 3.1 atm were determined. The dependence of the parabolic rate constant on the water vapor pressure yielded a power law exponent of one. Silica growth on Sic is therefore limited by transport of molecular water vapor through the silica scale.
Approaches to suppressing shaft voltage in non-insulated rotor brushless DC motor driven by PWM inverter (2013)

The voltage source PWM inverter generally used to drive the air conditioning (A/C) fans has been posing a large issue that the bearings in air conditioning fan motors are highly possible to be corroded electrically. Potential difference called shaft voltage is generated between inner and outer rings of the bearings due to inverter switching. The shaft voltage causes bearing lubricant breakdown dielectrically. As a result, bearing current is caused. This current causes the bearing corrosion. In previous work, we demonstrated that the shaft voltage can be reduced by using an insulator inserted between the outer and inner cores of the rotor in an air conditioning fan motor without grounding. This paper proposes the other countermeasure for reducing the shaft voltage in fan motors. The countermeasure which adds a capacitor between the brackets and the stator core is effective even for fan motors with non-insulated rotor. The effectiveness is confirmed by both simulated and experimental results..
The stability of electrical parameters of CdTe layers produced by metal - organic chemical vapour deposition (1997)

The stability of structures consisting of p-type high-resistivity epitaxial layers of CdTe grown by metal - organic chemical vapour deposition technology was studied by monitoring the capacitance and the AC and DC conductances of structures. The structures were grown on substrates differing in their conductivity type and composition. The structure parameters were measured in the frequency range 0.5 - 1000 kHz immediately after fabrication, after storage for half a year in the dark at room temperature and after ultrasonic processing. It was found that the stability of the epilayer parameters against ageing and acoustic treatments depended strongly on the substrate characteristics. The ageing and the epilayer degradation due to the ultrasonic processing were found to be a result of the diffusion of mobile acceptor defects from the substrate to the epilayer. The highest electric parameter stability was found for the epi-CdTe/n-CdTe structure. It is shown that the main reason for this stability is the potential barrier at the p - n junction, which prevents the acceptor defects from diffusing out of the substrate.
CeO<sub>2</sub>–TiO<sub>2</sub> Nanoparticle-Grafted gC<sub>3</sub>N<sub>4</sub> Sheets as an Efficient Catalyst for the Oxidation of Cyclohexane to KA oil (2022)

Here, we report a sustainable catalytic process operating on CeO2–TiO2 nanoparticle-grafted gC3N4 sheets (gC3N4/CeO2–TiO2) in the presence of a H2O2 green oxidant for the liquid phase oxidation of cyclohexane to produce KA oil (cyclohexanone + cyclohexanol). The process achieved enhanced cyclohexane conversion (62%) toward 95% KA oil (cyclohexanone 83% + cyclohexanol 12%), which is the highest ever reported to the best of our knowledge. The excellent catalytic behavior of gC3N4/CeO2–TiO2 in the present study due to its enhanced active sites, that is, Ce3+ and Ti3+, is facilitated by the redox reaction between CeO2–TiO2 and gC3N4 sheets. The high stability of gC3N4/CeO2–TiO2 catalyst in the liquid phase reaction study indicates the robust nature of this catalyst facilitated by strong interactions between CeO2–TiO2 species and electron-rich sites (N and π) of gC3N4 sheets. The overall study suggests that the gC3N4/CeO2–TiO2 material can be a promising catalyst for the sustainable production of KA oil from cyclohexane oxidation in the presence of the H2O2 oxidant.
Fabrication and characterization of high-temperature microreactors with thin film heater and sensor patterns in silicon nitride tubes (2005)

In this paper the fabrication and electrical characterization of a silicon microreactor for high-temperature catalytic gas phase reactions, like Rh-catalyzed catalytic partial oxidation of methane into synthesis gas, is presented. The microreactor, realized with micromachining technologies, contains silicon nitride tubes that are suspended in a flow channel. These tubes contain metal thin films that heat the gas mixture in the channel and sense its temperature. The metal patterns are defined by using the channel geometry as a shadow mask. Furthermore, a new method to obtain Pt thin films with good adhesive properties, also at elevated temperatures, without adhesion metal is implemented in the fabrication process. Based on different experiments, it is concluded that the electrical behaviour at high temperatures of Pt thin films without adhesion layer is better than that of Pt/Ta films. Furthermore, it is found that the temperature coefficient of resistance (TCR) and the resistivity of the thin films are stable for up to tens of hours when the temperature-range during operation of the microreactor is below the so-called "burn-in" temperature. Experiments showed that the presented suspended-tube microreactors with heaters and temperature sensors of Pt thin films can be operated safely and in a stable way at temperatures up to 700 degrees C for over 20 h. This type of microreactor solves the electrical breakdown problem that was previously reported by us in flat-membrane microreactors that were operated at temperatures above 600 degrees C.
Integrating Complementary Tools for Depth Imaging (2004)

Several field examples of Kirchhoff depth imaging, tomography, and wave-field extrapolation imaging are presented. These examples illustrate how compensation for anelastic attenuation, multiple attenuation, tomography, and wave-field extrapolation can be used in a complementary fashion to provide improved interpretation and imaging in areas of significant geologic complexity.
Characterization of High Temperature Creep Properties in Recrystallized 12Cr-ODS Ferritic Steel Claddings (2002)

The high temperature strengthening mechanism of previously manufactured 12Cr-ODS ferritic steel claddings was clarified. In the recrystallized 12Cr-2W-0.3Ti-0.24Y2O3-ODS ferritic steel cladding, αY2TiO5 type complex oxide formation was responsible for the drastic reduction of oxide particle size and the resulting shortened distance between particles, which led to superior internal creep rupture strength at 973 K because of the high resistance to gliding dislocation. Internal creep deformation was considered to be controlled by the grain boundary sliding associated with grain morphology: the near Σ11, Σ and Σ19 coincidence boundaries with a (110) common axis.
An Extensible Information Grid for Risk Management (2003)

&lt;div class="htmlview paragraph"&gt;This paper describes recent work on developing an extensible information grid for risk management at NASA — a RISK INFORMATION GRID. This grid is being developed by integrating information grid technology with risk management processes for a variety of risk related applications. To date, RISK GRID applications are being developed for three main NASA processes: risk management — a closed-loop iterative process for explicit risk management, program/project management — a proactive process that includes risk management, and mishap management — a feedback loop for learning from historical risks that ‘escaped’ other processes. This is enabled through an architecture involving an extensible database, structuring information with XML, ‘schema-less’ mapping of XML, and secure server-mediated communication using standard protocols.&lt;/div&gt;

Reconfigurable multi-beam pillbox antenna for millimeter wave automotive radars (2009)

This work proposes a multi-layer multi-beam reconfigurable pillbox antenna based on a novel transition between two substrates working as a quasi-optical system. The antenna consists of three main parts that can be designed and optimized independently: feeding part, quasi-optical system and radiating part. The novel quasi-optical system is made by several slots etched in the common metal layer and located along the entire length of an integrated parabolic reflector made by vertical metallic pins. The quasi-optical system shapes and focuses the energy traveling inside the lower layer to the radiating part made by an array of slotted waveguides. Several integrated horns placed in the focal plane of the integrated parabolic reflector are used to feed the quasi-optical system. Thanks to this feeding solution and the introduced quasi-optical system, multi-beam operation and beam reconfiguration capability on a wide angle field of view are achieved. The proposed structure is compatible with low-cost printed circuit board and substrate integrated waveguide technology. The low profile, low cost, efficiency and pattern reconfigurability of the proposed antenna make it very promising for the next generation of automotive radars.
Unnecessary use of fluoroquinolone antibiotics in hospitalized patients (2011)

In our institution, 39% of all days of fluoroquinolone therapy were unnecessary. Interventions that focus on improving adherence with current guidelines for duration of antimicrobial therapy and for management of urinary syndromes could significantly reduce overuse of fluoroquinolones.
Gold catalysis: helping create a sustainable future (2012)

In recent years there has been a general realisation that supported gold and gold bimetallic nanoparticles can be very effective for a broad range of redox reactions. In this paper we review the preparation of gold palladium nanoparticles using a sol-immobilisation methodology and show their effectiveness for the oxidation of benzyl alcohol and the direct synthesis of hydrogen peroxide.
Vibrating Insoles May Improve Balance in the Elderly (2004)

These authors report a novel technique for improving balance in healthy elderly people. The methodology relies upon a counterintuitive physical concept called stochastic resonance, in which the addition of noise to a system can actually enhance the normal function of that system (for a visual demonstration of how the addition of noise to a poor-quality photo can make the image clearer, see …
New Initiation System Delivers Improved Perforating Safety and Reliability While Maximizing Efficiency (2018)

Abstract In the perforating industry, operators, service companies, and manufacturers are constantly looking to improve shaped-charge performance and product quality and reliability while ensuring the highest levels of safety. More recently, there has been a heightened urgency to deliver improved operational efficiency considering recent industry downturns and the need to become more cost efficient. A new wireline perforating initiation system has been developed that addresses current industry challenges by improving reliability and efficiency while also improving the overall safety of wireline perforating operations. The development of a new initiation system for the conventional perforating market has built upon existing technologies previously developed for the unconventional market. The initiator system follows the guidelines of API RP67, fourth edition (in review at the time of publication), and has undergone detailed testing and validation before introduction to the field. The design has been qualified as an APIRP67 Group 2 initiator, which allows use without requiring radio silence in the conventional exclusion area. Field testing has demonstrated that the simplification of the preparation and arming process significantly improves operational efficiency and reduces the risk of human error. Additionally, by eliminating parts and simplifying maintenance, system reliability and usability is further improved. Selective guns are much simpler to prepare and arm, making the utilization of such gunstrings more appealing in areas where, in the past, they may not have been viable due to the additional complexity and/or associated arming time. This new gun system is currently being deployed in several areas around the world and has shown that it can deliver step-change improvements in reliability and efficiency with improved operational safety when working with explosives in wireline operations. This will have a significant impact on perforating operations, improving the safety of the field workforce while simultaneously improving operational efficiency.
Fibrosing Pseudotumor of the Sella and Parasellar Area Producing Hypopituitarism and Multiple Cranial Nerve Palsies (1993)

We present an unusual patient with a medical history of a fibrosing pseudotumor of the left orbit that had been stable for 8 years who presented with acute anterior hypophyseal failure. During the next 10-month period, sequential magnetic resonance scans showed a rapid growth of a plaque-like sellar and parasellar mass extending into the right cavernous sinus, right Meckel's cave, along the dural surfaces of the clivus, dens, and body of the second cervical vertebra. A transsphenoidal biopsy revealed sphenoid and intrasellar pseudotumor that invaded the adenohypophysis and had microscopic features identical to those of the previously excised orbital pseudotumor. Rapid growth of the pseudotumor continued despite a course of radiotherapy. Palsies of cranial nerves V and VI and of the sensory root of the cranial nerve VII developed on the right side. Steroid therapy was associated with improvement of the cranial nerve palsies. This is the first report of the sellar fibrosing pseudotumor producing not only anterior hypophyseal failure, but also cranial nerve dysfunction secondary to plaque-like extension into the cavernous sinus, Meckel's cave, and cranial base dura. This intracranial plaque-like extension of a fibrous pseudotumor corresponds to a hypertrophic intracranial pachymeningitis, which is a rare, previously described phenomenon associated to the syndrome of multifocal fibrosclerosis.

Drug Prescribing for Patients with Chronic Kidney Disease in General Practice: a Cross-Sectional Study
Dose-effect of interleukin-10 and its immunoregulatory role in Crohn's disease. (2003)

The in vitro model we used, demonstrates that IL-4, but mostly IL-10, efficiently suppresses TNF-alpha secretion in LPMNC from CD patients, with a dose-response curve similar to results obtained in vivo. Resistance at high rhIL-10 concentrations was associated with a change in the phenotype of TNF-alpha-secreting cells.
The path to 5G-Advanced and 6G Non-Terrestrial Network systems (2022)

Today, 5G networks are being worldwide rolled out, with significant benefits in our economy and society. However, 5G systems alone are not expected to be sufficient for the challenges that 2030 networks will experience, including, e.g., always-on networks, 1 Tbps peak data rate, <10 cm positioning, etc. Thus, the definition of evolutions of the 5G systems and their (r)evolutions are already being addressed by the scientific and industrial communities, targeting 5G-Advanced (5G-A) and 6G. In this framework, Non-Terrestrial Networks (NTN) have successfully been integrated in 3GPP Rel. 17 and it is expected that they will play an even more pivotal role for 5G-A (up to Rel. 20) and 6G systems (beyond Rel. 20). In this paper, we explore the path that will lead to 5G-A and 6G NTN communications, providing a clear perspective in terms of system architecture, services, technologies, and standardisation roadmap.
MSBNx: A Component-Centric Toolkit for Modeling and Inference with Bayesian Networks (2001)

We review the functionality of a modular, component-based tool kit for Bayesian network development and inference. Beyond its operation as a standalone modeling and inference environment, MSBNx facilitates the development of standalone applications by providing a set of run-time components that provide Bayesian reasoning services when integrated into other programs. MSBNx inferential operations provide both inference about states of inference and about the value of information for unobservered evidence. The services and modeling environment supports both diagnostic and troubleshooting mingles observations and repair operations. MSBNx facilitates the development and use of new add-in components. The modeling environment provides a means for assessing distinctions and beliefs, and special interfaces and tools for representing the asymmetric nature of probability distributions.

At the time of presentation chest radiography was normal. Except for the inguinal adenopathies, physical examination was unremarkable. Laboratory tests showed hypokalemia, inflammation and anemia.
Biological pathway expression complementation contributes to biomass heterosis in <i>Arabidopsis</i> (2021)

The mechanisms underlying heterosis have long remained a matter of debate, despite its agricultural importance. How changes in transcriptional networks during plant development are relevant to the continuous manifestation of growth vigor in hybrids is intriguing and unexplored. Here, we present an integrated high-resolution analysis of the daily dynamic growth phenotypes and transcriptome atlases of young <i>Arabidopsis</i> seedlings (parental ecotypes [Col-0 and Per-1] and their F<sub>1</sub> hybrid). Weighted gene coexpression network analysis uncovered divergent expression patterns between parents of the network hub genes, in which genes related to the cell cycle were more highly expressed in one parent (Col-0), whereas those involved in photosynthesis were more highly expressed in the other parent (Per-1). Notably, the hybrid exhibited spatiotemporal high-parent-dominant expression complementation of network hub genes in the two pathways during seedling growth. This suggests that the integrated capacities of cell division and photosynthesis contribute to hybrid growth vigor, which could be enhanced by temporal advances in the progression of leaf development in the hybrid relative to its parents. Altogether, this study provides evidence of expression complementation between fundamental biological pathways in hybrids and highlights the contribution of expression dominance in heterosis.
Vaccines targeting Staphylococcus aureus skin and bloodstream infections require different composition (2019)

Staphylococcus aureus infections represent a major public health threat, but previous attempts at developing a universal vaccine have been unsuccessful. We attempted to identify a vaccine that would be protective against both skin/soft tissue and bloodstream infections. We first tested a panel of staphylococcal antigens that are conserved across strains, combined with aluminum hydroxide as an adjuvant, for their ability to induce protective immunity in both skin and bacteremia infection models. Antigens were identified that reduced dermonecrosis during skin infection, and other non-overlapping antigens were identified that showed trends to protection in the bacteremia model. However, individual antigens were not identified that mediated substantial protection in both the skin and bacteremia infection models. We therefore tested a variety of combinations of proteins to seek a single combination that could mediate protection in both models. After iterative testing, a vaccine consisting of 3 antigens, ABC transporter protein (SACOL2451), ABC2 transporter protein (SACOL0695), and α-hemolysin (SACOL1173), was identified as the most effective combination. This combination vaccine provided protection in a skin infection model. However, these antigens were only partially protective in the bacteremia infection model. Even by testing multiple different adjuvants, optimized efficacy in the skin infection model did not translate into efficacy in the bacteremia model. Thus protective vaccines against skin/soft tissue infections may not enable effective protection against bloodstream infections.
&lt;title&gt;Application of queuing models to electronic toll collection&lt;/title&gt; (1998)

Electronic Toll Collection (ETC) via Automatic Vehicle Identification (AVI) technology has significantly altered traffic operations during toll collection. In particular, the value of the average processing rate of a lane providing both ETC service as well as a traditional service, fluctuates over the rush hour between the average value of the processing rate of the traditional service and the capacity of the ETC service. This study develops a queuing model to address the changing processing rates for the different mixed lanes. The model is applied to the westbound 9-lane portion of the Holland East Plaza in Orlando, FLorida. Data is evaluated for 6 different rush hours that include 3 different configuration patterns implemented over a period of 3 years. In the first configuration, only the traditional toll collection services are provided. In another configuration, all traditional lanes become mixed to include ETC except for the center lane, which becomes a lane dedicated solely to ETC service. In a final configuration, two lanes become dedicated to ETC service.
A COMPARISON OF THE HAEMODYNAMIC EFFECTS OF DIETARY SODIUM RESTRICTION AND ACUTE SODIUM DEPLETION IN THE CONSCIOUS SHEEP (1984)

The use of a low Na, low K sorghum grain diet supplemented with intraruminal electrolyte infusions has enabled dietary manipulation of sodium status to be studied in the sheep. Dietary sodium restriction reduced urinary sodium excretion within 24 h with maximal retention after 3 days. There were no other substantial metabolic or haemodynamic changes. A more severe form of sodium deficiency produced by parotid salivary drainage resulted after only 2 days in a sodium deficit 3-4 times that seen with 14 days of sodium restriction. Extracellular fluid volume and cardiac output decreased. Blood pressure was unchanged but there was an increase in peripheral resistance and plasma renin concentration.
