Theoretical Analysis of Erosion Phenomenon during Laser Brazing (2005)

Erosion phenomenon during the diode laser brazing of Inconel600 alloy with Au-18%Ni filler metal has been investigated. The erosion kinetics of isothermal and thermal cycle process was examined and analyzed with the Nernst-Brunner equation. The calculated amount of erosion in base metal by using single beam and tandem beam for preheating and brazing was compared with the experimental ; microstructural observation for the joint has shown that the amount of erosion increased with increasing the laser power. The calculated thickness of erosion was in good agreement with experimental value. It followed that the Nernst-Brunner equation seemed to be applicable to predict the erosion during laser brazing process. And the amount of erosion with tandem beam in the optimum condition was less than that with single beam brazing in spite of good wettability and spreadability against the base metal.
PRP and HSR version 1 (IEC 62439-3 Ed.2), improvements and a prototype implementation (2013)

The IEC62439-3: Industrial communication networks - High availability automation networks - Part 3: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR), defines two protocols which provides zero time recovery against a failure in the network. The first edition of the standard was published in 2010, and two years after a second edition has been published in July 2012. There have been some improvements which explain this actualization and an amendment between versions. This paper presents the most remarkable improvements included, others susceptible of being included and a software prototype to be run in PCs and/or FPGAs which implements this new version of the protocols.
Plasma α-Glutathione S- Transferase (2000)

Since plasma alphaGST levels increased earlier than plasma lactate and liver transaminase levels, alphaGST may be a more sensitive indicator of early liver injury and should be used in monitoring hepatocellular damage during the progression of sepsis.
On the solution conformation of bradykinin and certain fragments (1976)

&lt;P&gt;Abstract copyright UK Data Service and data collection copyright owner.&lt;/P&gt;The &lt;i&gt;Northern Ireland Family Expenditure Survey&lt;/i&gt; (NIFES) was conducted in Northern Ireland from 1967-1998, and was the counterpart to the &lt;i&gt;Family Expenditure Survey&lt;/i&gt; (FES), which was conducted annually in Great Britain from 1957-2001 (see under GN 33057). The FES/NIFES provided reliable data on expenditure and income in relation to household characteristics. The results of the survey show how expenditure patterns of different kinds of households vary, and the extent to which individual members of a household contribute to the household income. Although originally commissioned to provide expenditure details for the calculation of weights for the Retail Price Index, the FES/NIFES collected much additional information was also collected on the characteristics of co-operating households and the incomes of their members. It thus became a multi-purpose survey, and provided a unique fund of important economic and social data. &lt;br&gt;\n&lt;br&gt;\nFrom 1968 the Great Britain FES incorporated a sample drawn from the NIFES to become the UK FES. The FES was replaced in 2001 by a new survey series, the &lt;i&gt;Expenditure and Food Survey&lt;/i&gt; (EFS) (see under GN 33334), covering the whole of the UK. The EFS is an amalgamation of the previous &lt;i&gt;National Food Survey&lt;/i&gt; (NFS) (see under GN 33071) and UK FES.&lt;br&gt;\n&lt;br&gt;\n
Technology opportunities to enable high mass specific power (2009)

Inverted Metamorphic Multijunction (IMM) technology has demonstrated excellent energy conversion efficiency, 32% AM0. In addition to high conversion efficiency, this technology also offers the potential for ultra-high mass specific power at the blanket level. Because the substrate is removed, the thin, flexible epitaxial cell can be incorporated in a variety of novel blanket structures. Several novel array technologies have been proposed which would take advantage of the flexible nature of the IMM by incorporating rolled stowage for launch. The flexibility of the IMM may lead one to assume that the IMM is a much higher efficiency drop-in replacement for conventional thin-film photovoltaics (ex. amorphous silicon, copper indium gallium diselenide). An important differentiation between these technologies is the radiation hardness of the different technologies to the space environment. This paper presents a study to examine the photovoltaic blanket specific mass achievable with IMM technology depending upon the orbit of interest and the end-of-life performance requirement. The impact of radiation shielding, both front and back, is assessed.
WNT2 Locus is Involved in Genetic Susceptibility of Peyronie’s Disease (2012)

WNT2 is a susceptibility locus for PD and our finding provides evidence for a partly shared genetic susceptibility between PD and DD.
Computational Realization of a Non-Equidistant Grid Sampling in Photoacoustics with a Non-Uniform FFT (2015)

To obtain the initial pressure from the collected data on a planar sensor arrangement in Photoacoustic tomography, there exists an exact analytic frequency domain reconstruction formula. An efficient realization of this formula needs to cope with the evaluation of the datas Fourier transform on a non-equispaced mesh. In this paper, we use the non-uniform fast Fourier transform to handle this issue and show its feasibility in 3D experiments. This is done in comparison to the standard approach that uses polynomial interpolation. Moreover, we investigate the effect and the utility of flexible sensor location on the quality of photoacoustic image reconstruction. The computational realization is accomplished by the use of a multi-dimensional non-uniform fast Fourier algorithm, where non-uniform data sampling is performed both in frequency and spatial domain. We show that with appropriate sampling the imaging quality can be significantly improved. Reconstructions with synthetic and real data show the superiority of this method.

Immune imprinting, breadth of variant recognition, and germinal center response in human SARS-CoV-2 infection and vaccination (2022)

During the SARS-CoV-2 pandemic, novel and traditional vaccine strategies have been deployed globally. We investigated whether antibodies stimulated by mRNA vaccination (BNT162b2), including third-dose boosting, differ from those generated by infection or adenoviral (ChAdOx1-S and Gam-COVID-Vac) or inactivated viral (BBIBP-CorV) vaccines. We analyzed human lymph nodes after infection or mRNA vaccination for correlates of serological differences. Antibody breadth against viral variants is lower after infection compared with all vaccines evaluated but improves over several months. Viral variant infection elicits variant-specific antibodies, but prior mRNA vaccination imprints serological responses toward Wuhan-Hu-1 rather than variant antigens. In contrast to disrupted germinal centers (GCs) in lymph nodes during infection, mRNA vaccination stimulates robust GCs containing vaccine mRNA and spike antigen up to 8 weeks postvaccination in some cases. SARS-CoV-2 antibody specificity, breadth, and maturation are affected by imprinting from exposure history and distinct histological and antigenic contexts in infection compared with vaccination.

Pharmacoeconomics of antifungal pharmacotherapy – challenges and future directions (2005)

The frequency and severity of invasive fungal infections have been increasingly recognised and new antifungal therapies have expanded the therapeutic armamentarium available to manage such infections. Antifungal agents comprise a significant portion of antibiotic expenditures at major medical centres, prompting adoption of cost-containment measures and treatment guidelines. This paper reviews available data regarding the costs associated with managing fungal infections, including pharmacoeconomic analyses that have been performed in the setting of documented fungal infections, as well as prophylactic and empiric use of antifungal agents. The challenges of performing such studies are discussed, as well as the limitations of published investigations. Finally, recommendations are made regarding the design and implementation of future pharmacoeconomic analyses that can help establish the true costs of managing invasive fungal infections in at-risk patient populations.
Patch-clamp study of postnatal development of CA1 neurons in rat hippocampal slices: membrane excitability and K+ currents (1992)

1. The postnatal development of membrane properties and outward K+ currents in CA1 neurons in rat hippocampal slices was studied with the use of whole-cell patch-clamp techniques. 2. Neurons at all postnatal ages (2-30 days; P2-30) were capable of generating tetrodotoxin (TTX)-sensitive action potentials in response to intracellular injection of depolarizing current pulses. There was a gradual increase in the amplitude and a decrease in the duration of these action potentials with age. Stable values for spike duration were reached by P15, whereas spike amplitude increased until P20-25. In P2-5 neurons, the duration of action potentials was greatly prolonged by depolarization from the resting membrane potential, indicating a weak spike repolarizing mechanism at depolarized potentials. In contrast, the duration of spikes evoked in P20-30 neurons was not affected by similar changes in the membrane potential. 3. Application of tetraethylammonium (TEA, 10 mM) had no effect on the duration of spikes in P3-5 neurons, whereas application of 4-aminopyridine (4-AP, 2 mM) produced large increases in spike duration. In contrast, the duration of spikes in P26 neurons was greatly increased after TEA application, whereas 4-AP had smaller effects on spike duration in these neurons. 4. The input resistance and membrane time constant decreased with age from P2 to P15. The values for both parameters were considerably greater than those reported with conventional intracellular recording electrodes in the immature hippocampus. The resting membrane potential became more hyperpolarized with age. When the recording pipettes contained KCl (140 mM), the resting potential of P3-4 neurons was 34 mV depolarized compared with resting potentials observed with potassium gluconate-filled pipettes. Only a 13-mV change in resting potential was observed during similar comparisons in P27-28 neurons. 5. Outward currents activated by depolarization were examined with the use of voltage-clamp techniques in P2-30 neurons. In P2-5 cells, a small, slowly inactivating outward current was evoked with depolarizing commands from holding potentials near -50 mV. By preceding the depolarizing commands with a hyperpolarizing prepulse, an additional early transient outward current was evoked. The sustained and transient outward currents were separated by their kinetic properties and their sensitivity to cobalt (Co2+), TEA, and 4-AP.(ABSTRACT TRUNCATED AT 400 WORDS)
High‐Performance Electrochromic Optical Shutter Based on Fluoran Dye for Visibility Enhancement of Augmented Reality Display (2018)

Abstract In this paper, a high‐performance electrochromic optical shutter (ECOS) based on fluoran dye and an augmented reality (AR) display system comprising of ECOS are proposed. The electrochromic reactions of the fluoran dye that transmit or absorb visible light depending on its redox state are activated by the protons generated from hydroquinone derivatives, thereby significantly improved visible light absorption and decreased driving voltage. The visible light‐absorbing function of ECOS is a sole solution for overcoming the main issue of low visibility of displayed images under strong ambient light conditions in optical see‐through head‐mounted displays (OST‐HMDs) implementing augmented reality. The proposed AR display effectively solves the problem by significantly increasing the ambient contrast ratio and color gamut of the displayed image on OST‐HMD even in the strong ambient light condition due to the excellent visible light‐absorbing function of ECOS.
Zn-Doped Calcium Magnesium Phosphate Bone Cements Based on Struvite and Their Antibacterial Properties (2023)

The development of magnesium calcium phosphate bone cements (MCPCs) have garnered big attention. MCPCs are bioactive and biodegradable and have appropriate mechanical and antimicrobial properties for use in reconstructive surgery. In this study, the cement powders based on a (Ca + Mg)/P = 2 system doped with Zn2+ at 0.5 and 1.0 wt.% were obtained and investigated. After the mixing with a cement liquid, structural and phase composition, morphology, chemical structure, setting time, compressive strength, degradation behavior, solubility, antibacterial activities, and in vitro behaviour of the cement materials were examined. A high compressive strength of 48 &amp;plusmn; 5 MPa (mean &amp;plusmn; SD) was achieved for the cement made from Zn2+ 1.0-wt.%-substituted powders. The Zn2+ introduction led to antibacterial activity against Staphylococcus aureus and Escherichia coli strains, with an inhibition zone diameter up to 8 mm. Biological assays confirmed that the developed cements are cytocompatible and promising as a potential bone substitute in reconstructive surgery.
Multistep-Ahead Air Passengers Traffic Prediction with Hybrid ARIMA-SVMs Models (2014)

The hybrid ARIMA-SVMs prediction models have been established recently, which take advantage of the unique strength of ARIMA and SVMs models in linear and nonlinear modeling, respectively. Built upon this hybrid ARIMA-SVMs models alike, this study goes further to extend them into the case of multistep-ahead prediction for air passengers traffic with the two most commonly used multistep-ahead prediction strategies, that is, iterated strategy and direct strategy. Additionally, the effectiveness of data preprocessing approaches, such as deseasonalization and detrending, is investigated and proofed along with the two strategies. Real data sets including four selected airlines' monthly series were collected to justify the effectiveness of the proposed approach. Empirical results demonstrate that the direct strategy performs better than iterative one in long term prediction case while iterative one performs better in the case of short term prediction. Furthermore, both deseasonalization and detrending can significantly improve the prediction accuracy for both strategies, indicating the necessity of data preprocessing. As such, this study contributes as a full reference to the planners from air transportation industries on how to tackle multistep-ahead prediction tasks in the implementation of either prediction strategy.
A 120 GHz high-power whispering-gallery mode gyrotron (1993)

Abstract The design and the experimental results of a 120GHz, TE15, 2, 1 mode gyrotron are presented. The determination of an output mode and the designs of a cavity and an electron gun are described in some detail. In the initial pulse test on the tube, the oscillation mode map and the output mode pattern experimentally obtained showed that the designed TE15, 2, 1 cavity mode was successfully excited. The highest output power was 610 kW, corresponding to an efficiency of 30.6%. This was achieved at a beam voltage of 831 kV and a beam current of 24 A. The peak efficiency was 32.2%, achieved at 83.1 kV and 18.9 A, resulting in an output power of 506 kW. The purity of the output mode was also measured by a k-spectrometer. The output mode spectrum included several parasitic modes in addition to the main TE15, 2, 1 mode.
Development of Binaural Sensitivity: Eye Gaze as a Measure of Real-time Processing (2020)

Children localize sounds using binaural cues when navigating everyday auditory environments. While sensitivity to binaural cues reaches maturity by 8-10 years of age, large individual variability has been observed in the just-noticeable-difference (JND) thresholds for interaural time difference (ITD) among children in this age range. To understand the development of binaural sensitivity beyond JND thresholds, the "looking-while-listening" paradigm was adapted in this study to reveal the real-time decision-making behavior during ITD processing. Children ages 8-14 years with normal hearing (NH) and a group of young NH adults were tested. This novel paradigm combined eye gaze tracking with behavioral psychoacoustics to estimate ITD JNDs in a two-alternative forced-choice discrimination task. Results from simultaneous eye gaze recordings during ITD processing suggested that children had adult-like ITD JNDs, but they demonstrated immature decision-making strategies. While the time course of arriving at the initial fixation and final decision in providing a judgment of the ITD direction was similar, children exhibited more uncertainty than adults during decision-making. Specifically, children made more fixation changes, particularly when tested using small ITD magnitudes, between the target and non-target response options prior to finalizing a judgment. These findings suggest that, while children may exhibit adult-like sensitivity to ITDs, their eye gaze behavior reveals that the processing of this binaural cue is still developing through late childhood.
The use of angiogenic biomarkers in maternal blood to identify which SGA fetuses will require a preterm delivery and mothers who will develop pre-eclampsia (2015)

Angiogenic and anti-angiogenic factors measured in maternal blood between 24 and 34 weeks of gestation can identify the majority of mothers diagnosed with "suspected SGA" who subsequently developed PE or those who later required preterm delivery ≤ 34 weeks of gestation. Moreover, incorporation of these biochemical markers significantly improves risk assessment performance for these outcomes beyond that of clinical factors and uterine and umbilical artery Doppler velocimetry.
1-Methyl-1,4-cyclohexadiene as a Traceless Reducing Agent for the Synthesis of Catechols and Hydroquinones (2019)

Pro-aromatic and volatile 1-methyl-1,4-cyclohexadiene (<b>MeCHD</b>) was used for the first time as a valid H-atom source in an innovative method to reduce <i>ortho</i> or <i>para</i> quinones to obtain the corresponding catechols and hydroquinones in good to excellent yields. Notably, the excess of <b>MeCHD</b> and the toluene formed as the oxidation product can be easily removed by evaporation. In some cases, trifluoroacetic acid as a catalyst was added to obtain the desired products. The reaction proceeds in air and under mild conditions, without metal catalysts and sulfur derivatives, resulting in an excellent and competitive method to reduce quinones. The mechanism is attributed to a radical reaction triggered by a hydrogen atom transfer from <b>MeCHD</b> to quinones, or, in the presence of trifluoroacetic acid, to a hydride transfer process.

Wild edible mushrooms, a valuable resource for food security and rural development in Burundi and Rwanda (2016)

Description of the subject. This study is the first to compile the diversity of wild edible mushrooms gathered in the different ecosystems (savanna, woodland, montane forest, and exotic tree plantations) of Burundi and Rwanda and to consider this resource in a developmental framework for the region. Objectives. The aim of this study is to update the inventory of wild edible mushrooms in Burundi and Rwanda focusing on their sustainable exploitation and their potential for cultivation. Method. The inventory is based on a literature survey completed with referenced specimens gathered during field trips between 2010 and 2015 that are deposited at the Botanic Garden Meise (BR). Results. Seventy-seven species of edible mushrooms have been listed together with their habitat and ecology. This includes 39 new records of species eaten in the region, 8 of which were not previously known to be edible. An attempt to combine the protection of natural ecosystems with the development of local populations is presented in relation to the availability of these mushrooms, their ecology and cultivation potential. Conclusions. Wild edible mushrooms constitute an interesting and under-exploited resource in Burundi and Rwanda. Sustainable gathering of ectomycorrhizal species in miombo woodlands and cultivation of saprotrophic species from montane forests suggest important food issues and interesting business perspectives.
