Surveys of a small population of the Endangered Black-throated Finch Poephila cincta cincta in North Queensland (2023)

The Endangered southern subspecies of the Black-throated Finch Poephila cincta cincta survives in two recognised ‘strongholds’: parts of the Galilee Basin and the Townsville Plains, in Queensland. Elsewhere, there are apparently smaller populations scattered north of the Tropic of Capricorn. Between November 2014 and April 2018, 15 field surveys for Black-throated Finches were conducted on Toomba Station, a cattle property west of Charters Towers, North Queensland. Black-throated Finches were detected during five of these surveys, indicating the presence of a small and possibly isolated population. They were detected on 16 of the 65 survey days over a 3.5-year period. All but two detections were within 400 m of one of two water sources, one a cattle trough and the other a small farm dam. The habitat consisted principally of open woodland dominated by Narrow-leaved Ironbark Eucalyptus crebra and other Eucalyptus and Corymbia species. Blackthroated Finches were observed attending the two water sources, foraging and resting. The largest number seen was 13. Other observations detected 1–11 birds. These numbers, along with the limited number of sites at which the species was detected despite considerable search effort, suggest that the total population of the district is very small. Small and isolated populations are likely to be vulnerable to drought, local changes in land use and stochastic factors. Given the current threats to the Blackthroated Finch in its ‘strongholds’, it is important to ascertain the status, ecology and conservation needs of any remaining small, isolated populations of this subspecies.
Soluble Fraction from Lysates of Selected Probiotic Strains Differently Influences Re-Epithelialization of HaCaT Scratched Monolayer Through a Mechanism Involving Nitric Oxide Synthase 2 (2019)

A growing body of evidence supports the use of probiotics in the treatment of several skin conditions, including wounds. Even if in vitro and in vivo studies have highlighted the pro-healing effects of some probiotic bacteria, the underlying mechanisms are still not fully defined. The current investigation aimed to determine the re-epithelialization potential of the soluble fraction from lysate of seven different probiotic strains belonging to different genera (i.e., Streptococcus, Lactobacillus, and Bifidobacterium) on in vitro physically wounded HaCaT monolayer model. The results suggested that the soluble fraction of S. thermophilus, L. plantarum, and L. acidophilus promoted the re-epithelialization of scratched HaCaT monolayers, whereas those from B. longum, B. infantis, and B. breve significantly inhibited the process. On the other hand, L. bulgaricus showed no significant effect on in vitro wound repair. The mechanisms underlying the pro- or anti-healing properties of selected bacterial strains strictly and positively correlated with their ability to modulate nitric oxide synthase 2 (NOS2) expression and activity. Accordingly, the pre-treatment with aminoguanidine (AG), a specific inhibitor of NOS2 activity, abrogated the pro-healing effects of S. thermophilus, L. plantarum, and L. acidophilus.
MOVILIDAD SOCIAL INTERGENERACIONAL Y BIENESTAR INDIVIDUAL: EVIDENCIA EMPÍRICA DEL CASO BOLIVIANO (2013)

La movilidad social intergeneracional tiene una relación estrecha con el bienestar de un individuo. Sin embargo, la identificación de la fuerza de esta relación es muy compleja a razón, entre otros, de la complejidad misma del concepto de bienestar. El presente estudio aporta a la comprensión de esta relación en el caso boliviano, tomando en cuenta un concepto más amplio de bienestar individual que el ingreso/salario, el nivel de educativo o el status ocupacional, considerados como más tradicionales y que han guiado importantes estudios anteriores. A partir de la Encuesta de Movilidad y Estratificación Social (EMES-2009) realizada por PNUD Bolivia, que alimenta un modelo factorial basado en el Enfoque de Capacidades de Sen, se identifican dos aspectos complementarios del bienestar individual: la capacidad para el bienestar material y la capacidad para el bienestar subjetivo. Luego de construir métricas para ambos aspectos, se identifican algunos de sus determinantes, en base al Enfoque de Igualdad de Oportunidades de Roemer, con especial énfasis en el impacto que tienen algunas características del hogar de origen de los individuos, como la escolaridad del jefe, la de su cónyuge, el estilo de vida que ofrecía y la percepción de la clase social en el que se encontraba. Se presentan resultados contrastados para individuos en zonas urbanas y en zonas rurales del país, dando cuenta de rica y novedosa información cuantitativa sobre el grado de movilidad social intergeneracional en el país.
Grey Relational Analysis of Amine Inhibition of Mild Steel Corrosion in Acids (1997)

Grey relational analysis makes use of relatively simple mathematical procedures to arrive at salient relationships in a complex system. It uses a relatively small amount of data and works with great variability in factors. Grey relational analysis was used to investigate the relationship between inhibitor structure and inhibitor performance for a series of amines of different structures in the corrosion of mild steel in acids. Results showed the molecular weight (MW), the negative of the logarithm of the dissociation constant (pKa), and the number of nitrogen donor atoms influenced inhibitor effectiveness in the active region. The number of NH bonds was an additional factor for inhibition in the passive region. Trends in these factors were rationalized in terms of adsorptive interactions between the inhibitor molecules and the substrate. Results conformed to findings in the literature and were verified by additional measurements using hexamine as the inhibitor.
Histoire des pratiques sociales au Moyen Âge. Genre et famille (XIIe-XVe siècle) (2012)

Didier Lett, professeur à l’Université Paris-VII/Diderot Cette année, lors des six séances que j’ai faites à l’École (novembre et décembre 2010), j’ai d’abord proposé une réflexion générale sur la manière dont les historiens médiévistes ont fait et font actuellement l’histoire des pratiques sociales, fortement marquée par un certain nombre de courants historiographiques nourris par l’apport d’autres sciences sociales (sociologie et anthropologie principalement) (séance 1). Puisque mon enseign...
The effect of perturbation onset timing and length on tripping recovery strategies (2011)

In control subjects, trips during the early and late swing phase of walking elicit elevating and lowering strategies, respectively. However, the transition between these recovery strategies during mid-swing is unclear. A better understanding of this transition would provide insight into what factors cause individuals to choose one strategy over another. Three control subjects walked on a treadmill while attached to a custom-made tripping device. Perturbations of various lengths (ranging from 50 ms to 350 ms) were applied throughout the swing phase of gait. The results suggest that as perturbation length increased, the transition from elevating to lowering strategies occurred at earlier perturbation onsets. The transition period varied linearly with perturbation length. Perturbation lengths of 150 ms to 250 ms more closely replicated strategy selection in trips induced by real obstacles. Perturbations that are longer in duration force the transition from an elevating to a lowering strategy to occur at an earlier percentage of swing. These results show that perturbation length affects recovery strategy selection in response to trips.
Multicenter Evaluation of the Fully Automated COBAS AMPLICOR PCR Test for Detection of Chlamydia trachomatis in Urogenital Specimens (1999)

The fully automated COBAS AMPLICOR CT/NG test for the detection of Chlamydia trachomatis was evaluated in a multicenter trial. Test performance was evaluated for 2,014 endocervical swab and 1,278 urine specimens obtained from women and for 373 urethral swab and 254 urine specimens obtained from men. Culture served as the reference test. Culture-negative, COBAS AMPLICOR-positive specimens that tested positive in a confirmatory PCR test for an alternative target sequence within the C. trachomatis major outer membrane protein gene were resolved as true positives. The overall prevalence of chlamydia was 4.3% in cervical swabs and 11.0% in urethral swabs from men. When the results for each specimen type were considered separately, the resolved sensitivities were 96.5% (83 of 86) for endocervical swab specimens, 95.1% (39 of 41) for urine specimens from women, 100.0% (41 of 41) for urethral swab specimens from men, and 94.4% (17 of 18) for urine specimens from men; the resolved specificities were 99.4% (1,912 of 1,924) for endocervical swab specimens, 99.8% (1,204 of 1,207) for urine specimens from women, 98. 5% (325 of 330) for urethral swab specimens from men, and 100.0% (236 of 236) for urine specimens from men. For the subset of patients from whom both swab and urine specimens were collected, the combined results for both specimen types were used to identify all infected patients. Using these combined reslts as criteria, the resolved sensitivities for the COBAS AMPLICOR test were 82.6% (38 of 46) for endocervical swab specimens, 84.4% (38 of 45) for urine specimens from women, 84.2% (16 of 19) for urethral swab specimens from men, and 89.5% (17 of 19) for urine specimens from men. In comparison, the sensitivity of culture was only 56.5% (26 of 46) for endocervical specimens and 63.2% (12 of 19) for urethral specimens from men. The internal control provided in the COBAS AMPLICOR test revealed that 2.9% of specimens were inhibitory when they were initially tested. Nevertheless, valid results were obtained for 99. 1% of specimens because 68.7% of the inhibitory specimens were not inhibitory when a second aliquot of the original sample was tested. Two additional COBAS AMPLICOR-positive specimens were detected by retesting inhibitory specimens. The COBAS AMPLICOR CT/NG test for the detection of C. trachomatis exhibited equally high sensitivities and specificities with both urogenital swab and urine specimens and, thus, is well-suited for use in screening.
Model based TTCN-3 testing of industrial automation systems &#x2014; First results (2011)

Model-driven system/protocol engineering has been successfully applied in the industrial automation domain over the recent years. However, its cousin model-based testing (MBT) is relatively a new kid in the block - who is being curiously observed by domain experts. MBT leverages behavior models (e.g. software models) to automatically generate a large set of test cases. Testing industrial communication and automation systems manually for all significant behavioral scenarios is a non-trivial task. Hence, automatic generation of test vectors from formal/semi-formal models is desirable. Here, we report our first step towards the usage of MBT in the industrial automation context.
Optomechanical Scanning Applications, Techniques, and Devices (1993)

The field of scanning is extremely broad. Any scanning system is a complex arrangement of optical, mechanical, electrical, and electronic subsystems. This chapter is limited to scanning techniques that apply to reasonably fast and accurate systems as they are encountered in infrared applications. This chapter focuses on the subsystem that specifically provides the scanning capability. It does not cover the pre- or post-scanning optics nor the associated detectors, electronics, controls, logics, or software.
Numerical and Experimental Investigation on Bonding Behavior of Cold Sprayed Porous WC-17Co Particles onto Different Substrates (2018)

Cold sprayed WC-Co metal matrix composite coatings have shown great potential in wear-resistance applications. This work aims to use experimental and numerical methods to clarify the deposition and particle–substrate bonding behavior of a single porous WC-17Co particle onto various substrates. To achieve this objective, porous WC-17Co particles were used as the feedstock; soft Al 2024 (Al alloy) and hard stainless steel 316 (SS) were used as the substrates. The experimental results revealed that brittle WC-Co particles tended to remain intact after depositing on a soft Al alloy substrate, but underwent serious fracture when impacting on a hard SS substrate. Further results indicated that the high energy dissipation and the consequent high stress concentration in the WC-Co particle was the main reason for inducing the particle fracture. In addition, two different mechanical interlocking mechanisms were identified during the WC-Co particle deposition process (namely WC reinforcement interlock and WC-Co particle interlock), dominating the particle-substrate bonding. A soft Al alloy substrate resulted in better interlocking than a hard SS substrate, thereby the corresponding particle bonding ratio was also much higher.

Tunable Birefringent Filters (1981)

This article reviews the types and capabilities of birefringent filters. The general operating principles of Lyot (perfect polarizers), partial polarizing, and Solc (no internal polarizers) filters are introduced. Appropriate techniques for tuning each filter type are presented. Field of view of birefringent filters is discussed and is compared to Fabry-Perot and interference filters. The trans-mission and throughput advantages of birefringent filters are shown. Finally, the current state of the art in practical filters is reviewed.
Interface nucleation rate limited densification during sintering (2022)

In situ bicrystal sintering experiments performed in a transmission electron microscope indicate that the densification rate can follow interface nucleation rate limited kinetics. This work performs in situ sintering experiments on immiscible Al2O3-GdAlO3 interfaces enabling a statistical treatment of sintering at a single interface type as a function of time and temperature. The data provide a measure for the activation energy of the nucleation process, ≈4.8 eV. This large value is consistent with observations that the process is rate limiting. A new sintering model is developed based on the assumption of interface nucleation rate limited kinetics and is demonstrated to work well in predicting in situ bicrystal sintering data, fitting in situ multiparticle sintering data, predicting grain size versus density sintering trajectories, and fitting isothermal bulk sintering data.
Carbonate and Thorium concentrations of South Atlantic sediments (1964)

Rates of sedimentation of pelagic sediments in the South Atlantic have been determined using the ionium/thorium methodology. Values of the order of several millimeters per thousand years for sediments were found in the deposits in the valleys of the mid-Atlantic ridge. The equatorial deposits showed higher rates of accumulation than the corresponding deposits at higher latitudes, probably reflecting the added influx of materials to the sea floor from tropical rivers through the equatorial current systems. The deposits in the ridge valleys showed marked changes in sedimentation rates at about 115,000 years ago, at which time the present rates changed from higher to lower values. The ridge sediments were composed primarily of continentally derived materials, and there were no indications of solid phases being derived from the weathering of the ridge itself or from volcanic activity. The equatorial samples have mineral assemblages which are distinctly different from those in deposits at higher latitudes and which probably are indicative of contributions of materials from tropical weathering processes.
Sputtered Indium-Tin-Oxide on p-GaN (2007)

To study plasma-induced damages, we directly sputtered indium-tin-oxide (ITO) films onto p-GaN and systematically studied the effects of sputter power on the electrical properties of ITO/p-GaN. It was found that plasma bombardment during sputtering will induce nitrogen vacancies and compensate acceptor concentration in p-GaN or even convert p-GaN into n-GaN. It was also found that annealing the samples at 600 and will generate more nitrogen vacancies and enhance rectifying behavior. Furthermore, it was found that annealing could effectively recover the plasma-induced nitrogen vacancies and/or traps.
Monocytosis as an Index of TNT Absorption (1946)

During the performance of routine full blood counts on men and women workers in a Royal Ordnance Factory handling trinitrotoluene (TNT), a rise in the absolute number of large mononuclear leucocytes (monocytes), was frequently observed. It was hoped that the presence of this rise might indicate early toxicity and so help to decide whether gastric or other symptoms in such a worker were due to TNT, or merely coincidental. Webster's urine test is useless for this purpose, since it merely indicates the excretion of TNT products, and not whether the patient is poisoned. To test this hypothesis further, four groups of workers were taken and examined : (i) Fifty-four workers in contact with TNT with gastric symptoms or other symptoms known to be produced by TNT intoxication, such as tightness in the chest, pallor and fatigue, and anilism (slatey-blue cyanosis). (ii) Fifty-one workers in contact with TNT with no symptoms. (iii) A hundred and two normal controls. (iv) Forty non-contact cases with gastric symptoms.
Can Silver Be Alloyed with Bismuth on Nanoscale? An Optical and Structural Approach (2016)

The bulk AgBi alloy system comprises a wide forbidden range of Ag solubility limited to a negligible molar fraction. In this contribution it is unambiguously demonstrated that Ag and Bi, elements with various in-common potential applications, can be alloyed on nanoscale, which is hugely different from the bulk form. These nanostructured Ag–Bi alloys are prepared by a mechano-chemistry pathway under normal conditions and without large amounts of solvents. The characterization of the nanoparticles by combination of UV–visible absorption and Raman spectroscopies as well as SEM, HAADF-STEM, XRD, and DSC lead to the finding of these sui generis nanoalloys and the unprecedented proposal of a predominantly atomic mixed alloyed structure for the AgxBi1–x (0.1 ≤ x ≤ 0.5) clusters. This arrangement allows the coexistence of bulk-like lattices of zerovalent Bi and Ag. These resulting nanoparticles can effectively degrade NO; however, they are rapidly oxidized.
Biofuel Cell Based on Microscale Nanostructured Electrodes with Inductive Coupling to Rat Brain Neurons (2013)

Miniature, self-contained biodevices powered by biofuel cells may enable a new generation of implantable, wireless, minimally invasive neural interfaces for neurophysiological in vivo studies and for clinical applications. Here we report on the fabrication of a direct electron transfer based glucose/oxygen enzymatic fuel cell (EFC) from genuinely three-dimensional (3D) nanostructured microscale gold electrodes, modified with suitable biocatalysts. We show that the process underlying the simple fabrication method of 3D nanostructured electrodes is based on an electrochemically driven transformation of physically deposited gold nanoparticles. We experimentally demonstrate that mediator-, cofactor-, and membrane-less EFCs do operate in cerebrospinal fluid and in the brain of a rat, producing amounts of electrical power sufficient to drive a self-contained biodevice, viz. 7 μW cm(-2) in vitro and 2 μW cm(-2) in vivo at an operating voltage of 0.4 V. Last but not least, we also demonstrate an inductive coupling between 3D nanobioelectrodes and living neurons.
Notch family members follow stringent requirements for intracellular domain dimerization at sequence-paired sites (2020)

Notch signaling is essential for multicellular life, regulating core functions such as cellular identity, differentiation, and fate. These processes require highly sensitive systems to avoid going awry, and one such regulatory mechanism is through Notch intracellular domain dimerization. Select Notch target genes contain sequence-paired sites (SPS); motifs in which two Notch transcriptional activation complexes can bind and interact through Notch's ankyrin domain, resulting in enhanced transcriptional activation. This mechanism has been mostly studied through Notch1, and to date, the abilities of the other Notch family members have been left unexplored. Through the utilization of minimalized, SPS-driven luciferase assays, we were able to test the functional capacity of Notch dimers. Here we show that the Notch 2 and 3 NICDs also exhibit dimerization-induced signaling, following the same stringent requirements as seen with Notch1. Furthermore, our data suggested that Notch4 may also exhibit dimerization-induced signaling, although the amino acids required for Notch4 NICD dimerization appear to be different than those required for Notch 1, 2, and 3 NICD dimerization. Interestingly, we identified a mechanical difference between canonical and cryptic SPSs, leading to differences in their dimerization-induced regulation. Finally, we profiled the Notch family members' SPS gap distance preferences and found that they all prefer a 16-nucleotide gap, with little room for variation. In summary, this work highlights the potent and highly specific nature of Notch dimerization and refines the scope of this regulatory function.
ROAD GRADE AND VEHICLE PARAMETER ESTIMATION FOR LOGITUDINAL CONTROL USING GPS. (2001)

This paper demonstrates two methods for obtaining an estimate of road grade using a Global Positioning System (GPS) system on a ground vehicle. In the first method, two antennae are used to directly measure the attitude of the vehicle in the pitch plane; in the second method, the ratio of vertical to horizontal velocity at a single antenna is used to estimate road grade. Both methods are implemented experimentally and their relative sensitivities to corruption by vehicle pitch and bounce motion characterized. The resulting grade measurements are then used together with engine torque information to produce estimates of mass, rolling resistance and aerodynamic drag from a simple longitudinal force balance. The resulting mass estimation consistently converged to within f 2 YO of the true vehicle mass. Another variable that has a profound effect on vehicle performance is the road grade. Modest road grades may prove to be quite a challenge for vehicles with low power- to-weight ratio such as ab:omated commercial heavy vehicles. Figure 1 shows the relative capability of a heavy truck engine and the demands from grade and aerodynamics as a function of speed. At highway speeds (about 20 ds), a typical commercial heavy vehicle has little capability for acceleration in reserve since most of the engine output must go to counteract aerodynamic drag and rolling resistance. A 4% road grade can be a severe loading to such vehicle:<. This is why, in most cases, heavy vehicles have to slow down considerably going up steep grades, sacrificing speed in order to get more power from engine.
