A component-based approach to design and analysis of dependable MAC protocols for wireless sensor networks (2009)

This article discusses a new methodology for the systematic composition of wireless sensor networks utilizing component-based modeling of MAC protocols. The methodology is intended for the use in applications that have a predefined topology and traffic pattern while requiring dependable performance, which is typical for critical infrastructures. The need for such methodology stems from the variety of applications with different performance and dependability requirements on the one hand and unavailability of unified system architectures for sensor networks on the other. The paper suggests a work flow for the composition of protocols where the performance requirements and characteristics of the installation environment are used in the selection for components and their parametrization. It is shown how different instances of MAC protocols (known as monolithic solutions) could be achieved by different parameterizations of an abstract MAC model. For the selection of the components and parameterizations deterministic models for the communication process are suggested in order to quantify the significance of parameters and components for the performance. The quantification is expected to be achieved using concept from the areas of control structure design and performance limitations in control theory.
Regenerability of Hydrotalcite‐Derived Nickel–Iron Alloy Nanoparticles for Syngas Production from Biomass Tar (2013)

Nickel-iron/magnesium/aluminum bimetallic catalysts were prepared by the calcination and reduction of nickel-magnesium-iron-aluminum hydrotalcite-like compounds. Characterization suggests that, at iron/nickel≤0.5, both nickel and iron species are homogeneously distributed in the hydrotalcite precursor and incorporated into the Mg(Ni, Fe, Al)O periclase after calcination, giving rise to uniform nickel-iron alloy nanoparticles after reduction. Ni-Fe/Mg/Al (Fe/Ni=0.25) exhibits the best catalytic performance for the steam reforming of tar derived from the pyrolysis of biomass. It is suggested that the uniform nickel-iron alloy nanoparticles and the synergy between nickel and iron are responsible for the high catalytic performance. Moreover, the Ni-Fe/Mg/Al catalyst exhibits much better regenerability toward oxidation-reduction treatment for the removal of deposited coke than that of conventional Ni-Fe/α-Al2 O3 . This property can be attributed to the better regeneration of Ni-Fe alloy nanoparticles through the formation and reduction of Mg(Ni, Fe, Al)O.

Evaluation and mitigation of reactive ion etching-induced damage in AlGaN/GaN MOS structures fabricated by low-power inductively coupled plasma (2020)

Abstract AlGaN/GaN metal-oxide-semiconductor (MOS) structures were fabricated by low-power inductively coupled plasma reactive ion etching (ICP-RIE) and chemical vapor deposition of SiO 2 dielectrics on the etched surfaces, and they were systematically investigated by physical and electrical characterizations in an effort to develop a low-damage recessed gate process. Although ICP-RIE with reduced bias power was able to suppress nitrogen deficiencies and native oxide growth on damaged AlGaN surfaces, compositional changes due to selective aluminum removal were found to be inevitable. On the other hand, thin damaged layers were completely oxidized to form GaO x interface layers at the initial stage of SiO 2 deposition, leading to dielectric/etched-AlGaN interfaces with excellent electrical properties. Furthermore, Hall-effect measurements showed negligible impact on the two-dimensional electron gas beneath the AlGaN layers etched under very low bias conditions. The current comprehensive research demonstrates the significant advantages of the proposed low-damage recessed gate process for fabricating next-generation AlGaN/GaN MOS-HFET devices.
Specific detection by PCR of Streptococcus agalactiae in milk. (2001)

The aim of this study was to develop a simple and specific method for direct detection of Streptococcus agalactiae from cow's milk. The method was based on polymerase chain reaction (PCR) using species-specific and universal primers derived from the 16S rRNA gene. The amplification product was verified by restriction endonuclease digest and sequencing. Specific identification was proven on a collection of 147 S. agalactiae isolates of bovine and human origin. In addition, 17 strains belonging to different bacterial species that potentially can be found in milk samples also tested negative. The PCR developed was used for direct detection of S. agalactiae in milk, using for the first time with gram-positive bacteria the nucleic acid-binding properties of diatomaceous earth. The test, which has high specificity, high sensitivity (100 cfu/mL), and can be carried out in less than 24 h, represents an innovative diagnostic tool for the detection of S. agalactiae in milk.
Nonlinear photoluminescence imaging applied to femtosecond laser manufacturing of fiber Bragg gratings (2017)

Nonlinear photoluminescence imaging is used to visualize the intensity distribution of femtosecond laser pulses inside the optical fiber during Bragg grating inscription based on side illumination through a phase mask. This technique, which results in direct imaging of the inscription laser field inside the optical fiber, facilitates i) the characterization of the laser focus in the vicinity of the fiber core and ii) the optimization of the fiber alignment with respect to the laser focus while using pulses with energies several times lower than those used during the actual inscription process. The applicability of this imaging technique is demonstrated for Bragg grating inscription in different optical fibers, including direct inscription through the fiber coating.

Measurement of colour flow using jet-pull observables in $$t\bar{t}$$ t t ¯ events with the ATLAS experiment at $$\sqrt{s} = 13\,\hbox {TeV}$$ s = 13 TeV (2018)

Previous studies have shown that weighted angular moments derived from jet constituents encode the colour connections between partons that seed the jets. This paper presents measurements of two such distributions, the jet-pull angle and jet-pull magnitude, both of which are derived from the jet-pull angular moment. The measurement is performed in <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>t</mml:mi> <mml:mover><mml:mrow><mml:mi>t</mml:mi></mml:mrow> <mml:mrow><mml:mo>¯</mml:mo></mml:mrow> </mml:mover> </mml:mrow> </mml:math> events with one leptonically decaying <i>W</i> boson and one hadronically decaying <i>W</i> boson, using <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mn>36.1</mml:mn> <mml:mspace></mml:mspace> <mml:msup><mml:mtext>fb</mml:mtext> <mml:mrow><mml:mo>-</mml:mo> <mml:mn>1</mml:mn></mml:mrow> </mml:msup> </mml:mrow> </mml:math> of <i>pp</i> collision data recorded by the ATLAS detector at <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow><mml:msqrt><mml:mi>s</mml:mi></mml:msqrt> <mml:mo>=</mml:mo> <mml:mn>13</mml:mn> <mml:mspace></mml:mspace> <mml:mtext>TeV</mml:mtext></mml:mrow> </mml:math> delivered by the Large Hadron Collider. The observables are measured for two dijet systems, corresponding to the colour-connected daughters of the <i>W</i> boson and the two <i>b</i>-jets from the top-quark decays, which are not expected to be colour connected. To allow the comparison of the measured distributions to colour model predictions, the measured distributions are unfolded to particle level, after correcting for experimental effects introduced by the detector. While good agreement can be found for some combinations of predictions and observables, none of the predictions describes the data well across all observables.

An implicit finite-difference code for a two-equation turbulence model for three-dimensional flows (1985)

An implicit finite difference code was developed which solves the transport equations for the turbulence kinetic energy and its dissipation rate in generalized coordinates in three dimensions. The finite difference equations are solved using the Beam-Warming algorithm. The kinetic energy-dissipation code, KEM, provides the closure; i.e., the turbulent viscosity for calculation of either compressible or incompressible flows. Turbulent internal flow over a backward-facing step has been calculated using the present code in conjunction with the Incompressible Navier-Stokes Code, INS3D. The results are in good agreement with experiments and two dimensional computations of other researchers.

Tunable external cavity laser diode based on wavelength controlled self-assembled InAs quantum dots for swept-source optical coherence tomography applications at 1100 nm wavelength band (2019)

We fabricated and characterized a grating-coupled external cavity laser with gain chips including self-assembled InAs quantum dots (QDs) for swept-source optical coherence tomography applications. By controlling the emission wavelength of the self-assembled InAs QDs, tunable lasing at a wavelength band of 1–1.1 μm was obtained, which represents an optimal balance between absorption and scattering in biological tissues. Straight and J-shaped edgeemitting ridge waveguides (RWGs) were fabricated on a GaAs-based waveguide layer containing four InAs QDs layers. A diffraction grating with the quasi-Littrow configuration was employed as an external cavity for the fiber-coupled diodes. Electroluminescence spectra from the QD-based diodes revealed that broadband amplified spontaneous emissions appeared in a J-shaped RWG, whereas Fabry–Perot lasing occurred in the straight RWG. The external cavity was then introduced for the diode with a J-shaped RWG, and a tuning range of 65 nm centered at approximately 1100 nm was obtained from the QD gain chip with the J-shaped RWG.
Interplay of Processing and Radio Parameters: A Service-Oriented Performance Study (2019)

In this paper, we propose general service-oriented end-to-end energy and delay models. They facilitate the evaluation of new schemes, by enabling flexible allocation of processing functions at multilayer radio access network. These models describe the underlaying processing of communication function (PCF)'s complexity and the induced bandwidth. We also introduce the concept of processing interference and link it to the average PCF option of the competing users at the cloud. The proposed framework shows the possibility to compensate the delay or energy degradation, e.g., due to radio environment, by reallocating processing parameters, e.g., allocation of PCF or number of virtual central processing units (VCPUs). Several conclusions are inferred from the system's evaluation. For instance, at low modulation index (MI), the behavior of overall energy consumption is dominated by PCF energy, not the transmission energy, whereas, at high MI, the behavior of overall energy consumption is dominated by transmission energy. Centralization of PCF reduces the impact of processing interference (of competing users) on the targeted service's delay from 11 to 2 ms, and service's energy consumption from 18 to 2 J. We further evaluate the impact of PCF on the decision of offloading the service, to be computed at the cloud.
Engineering Infrared Quantum Fluctuations to Generate Light from UV through Gamma Rays (2018)

We show that plasmonic vacuum fluctuations can lead to a passive radiation source at UV to gamma ray energies. Its per-electron power is comparable to synchrotrons with a 1 Tesla field and is density-of-states tunable.
Modelling and computational improvements to the simulation of single vector-boson plus jet processes for the ATLAS experiment (2022)

A bstract This paper presents updated Monte Carlo configurations used to model the production of single electroweak vector bosons ( W , Z/γ ∗ ) in association with jets in proton-proton collisions for the ATLAS experiment at the Large Hadron Collider. Improvements pertaining to the electroweak input scheme, parton-shower splitting kernels and scale-setting scheme are shown for multi-jet merged configurations accurate to next-to-leading order in the strong and electroweak couplings. The computational resources required for these set-ups are assessed, and approximations are introduced resulting in a factor three reduction of the per-event CPU time without affecting the physics modelling performance. Continuous statistical enhancement techniques are introduced by ATLAS in order to populate low cross-section regions of phase space and are shown to match or exceed the generated effective luminosity. This, together with the lower per-event CPU time, results in a 50% reduction in the required computing resources compared to a legacy set-up previously used by the ATLAS collaboration. The set-ups described in this paper will be used for future ATLAS analyses and lay the foundation for the next generation of Monte Carlo predictions for single vector-boson plus jets production.
Exploring novel aryl/heteroaryl-isosteres of phenylthiazole against multidrug-resistant bacteria (2023)

Antimicrobial resistance has become a concern as a worldwide threat. A novel scaffold of phenylthiazoles was recently evaluated against multidrug-resistant <i>Staphylococci</i> to control the emergence and spread of antimicrobial resistance, showing good results. Several structural modifications are needed based on the structure-activity relationships (SARs) of this new antibiotic class. Previous studies revealed the existence of two key structural features essential for the antibacterial activity, the guanidine head and lipophilic tail. In this study, a new series of twenty-three phenylthiazole derivatives were synthesized utilizing the Suzuki coupling reaction to explore the lipophilic part. The <i>in vitro</i> antibacterial activity was evaluated against a range of clinical isolates. The three most promising compounds, 7d, 15d and 17d, with potent MIC values against MRSA USA300 were selected for further antimicrobial evaluation. The tested compounds exhibited potent results against the tested MSSA, MRSA, and VRSA strains (concentration: 0.5 to 4 μg mL<sup>-1</sup>). Compound 15d inhibited MRSA USA400 at a concentration of 0.5 μg mL<sup>-1</sup> (one-fold more potent than vancomycin) and showed low MIC values against ten clinical isolates, including linezolid-resistant strain MRSA NRS119 and three vancomycin-resistant isolates VRSA 9/10/12. Moreover, compound 15d retained its potent antibacterial activity using the <i>in vivo</i> model by the burden reduction of MRSA USA300 in skin-infected mice. The tested compounds also showed good toxicity profiles and were found to be highly tolerable to Caco-2 cells at concentrations of up to 16 μg mL<sup>-1</sup>, with 100% of the cells remaining viable.
Sub-surface characterization and three dimensional profiling of semiconductors by magnetic resonance force microscopy (1996)

This is the final report of a two-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project successfully developed a magnetic resonance force microscope (MRFM) instrument to mechanically detect magnetic resonance signals. This technique provides an intrinsically subsurface, chemical-species-specific probe of structure, constituent density and other properties of materials. As in conventional magnetic resonance imaging (MRI), an applied magnetic field gradient selects a well defined volume of the sample for study. However mechanical detection allows much greater sensitivity, and this in turn allows the reduction of the size of the minimum resolvable volume. This requires building an instrument designed to achieve nanometer-scale resolution at buried semiconductor interfaces. High-resolution, three-dimensional depth profiling of semiconductors is critical in the development and fabrication of semiconductor devices. Currently, there is no capability for direct, high-resolution observation and characterization of dopant density, and other critical features of semiconductors. The successful development of MRFM in conjunction with modifications to improve resolution will enable for the first time detailed structural and electronic studies in doped semiconductors and multilayered nanoelectronic devices, greatly accelerating the current pace of research and development.
An in-wheel motor-based tyre test vehicle (2007)

An experimental three-wheel electrical vehicle has been developed in order to provide a platform for experimental verifications of advanced tyre friction models, estimators and controllers. The vehicle comprises a high-torque permanent-magnet synchronous motor built in the front wheel and precise incremental encoders for the front- and rear-wheel speed measurements. The paper presents a description of the vehicle and gives characteristic experimental procedures and results related to motor static and dynamic behaviour. Experimental results on tyre friction identification are also presented.
S770 Health-Related Quality of Life With Ustekinumab vs Adalimumab for Induction and Maintenance Therapy in Biologic-Naïve Patients With Moderate-To-Severe Crohn’s Disease: IBDQ in the SEAVUE Study (2021)

Introduction: Crohn’s disease (CD) impacts physical and mental well-being, which can negatively affect health-related quality of life (HRQoL). The Inflammatory Bowel Disease Questionnaire (IBDQ), a disease-specific measure of HRQoL, was used to assess the effects of ustekinumab (UST) and adalimumab (ADA) on HRQoL in biologic-naïve patients with CD enrolled in the SEAVUE study. Methods: SEAVUE was a multicenter, randomized, blinded, parallel-group, active-controlled study in biologic-naïve adults with CD Activity Index (CDAI) scores ≥220/≤450. Patients were randomized 1:1 to UST (∼6mg/kg IV at baseline then 90mg SC every 8 weeks) or ADA (160/80mg SC at baseline/Week 2, then 40mg SC every 2 weeks) per US-approved regimens. Dose modification was not allowed. Using the IBDQ, which includes an overall score and 4 dimension scores (bowel symptoms, systemic symptoms, emotional function, and social function), we evaluated improvement in HRQoL from baseline through 1 year in these patients. Results: Among 386 patients randomized to UST or ADA, baseline demographics and disease characteristics were balanced between groups (median CD duration, 2.58 years; CDAI, 289.5; Simple Endoscopic Score for CD, 8.0). Baseline mean [standard deviation] IBDQ scores were similar between the treatment groups (IBDQ: 116.6 [30.7] UST, 121.9 [31.6] ADA; bowel symptoms: 37.4 [9.6] UST, 39.2 [9.5] ADA; emotional function: 44.0 [13.0] UST, 45.6 [13.3] ADA; systemic symptoms: 15.0 [5.1] UST, 16.1 [5.5] ADA; social function: 20.4 [7.4] UST, 20.9 [7.7] ADA). In both groups, improvements in the overall IBDQ and dimension scores were observed as early as Week 8 (data not shown) and increased through Week 52 (Table 1). At Week 52, mean improvement from baseline in overall IBDQ score was 50 points with UST and 43 points with ADA, and a ≥16-point improvement from baseline in IBDQ score was achieved by 67% of patients in the UST group and 63% of patients in the ADA group. Conclusion: UST and ADA similarly improved the IBDQ overall and dimension scores through Week 52 in biologic-naïve patients with moderate-to-severe CD. These results are consistent with those previously reported in biologic-naïve patients with CD1 or ulcerative colitis2 and provide further evidence of the benefit of effective treatment in improving the HRQoL of patients with inflammatory bowel disease.Table 1
