The indoor SLAM using multiple three dimension sensors integration (2009)

The high performance mobile robots nowadays should operate themselves in many applications. One attractive task is to build the map, meanwhile estimate their poses for the locomotion in real time. The simultaneous localization and mapping (SLAM) technique is once technique which can solve this demand. The selecting sensors are essential factors for generation the high accuracy output. This paper present, the applying a new 3D sensor namely the photonic mixer devices (PMD) provides a real-time capturing of surrounding volume. However the output of PMD is very excellent depth metric, to recognize the complex objects is still faultily because of the low resolution output (64 × 48 pixels). The 2D high resolution camera inspires to compensate the PMD camera's drawback. The high resolution image output is registered on the 3D volume. The visual input from the 2D camera does not delivers only high resolution texture data on 3D volume but it is also used for object recognition. Finally, the iterative closest point (ICP) algorithm is used for the image registration in order to yield the real time 3D data frames registration.

Wind Direction and Equilibrium Mixed Layer Depth: General Theory (1985)

A usually neglected Coriolis term in the turbulent kinetic energy budget of the ocean surface mixed layer is examined for the special case of a steady-state mixed layer depth with no entrainment. In this term, the Reynolds stresses interact with the northward component of planetary rotation to exchange turbulent kinetic energy between horizontal and vertical components. The direction of the exchange depends upon the sign of east-west component of the wind stress. A vertically integrated or bulk theory is derived for a non-entraining mixed layer in equilibrium. The results show that the vertical turbulent kinetic energy and hence the vertical mixing and mixed layer depth will be reduced for westerly winds. Fasterly winds will increase vertical mixing and mixed layer depth.
Olive-oil Phenolics and Health: Potential Biological Properties (2008)

Extra virgin olive oil, the primary source of oil in the Mediterranean diet, differs significantly in composition from dietary lipids that are consumed by other populations. The several minor constituents of virgin olive oil include vitamins such as alpha-and gamma-tocopherols (around 200 ppm) and beta-carotene, phytosterols, pigments, terpenic acids, flavonoids, squalene, and a number of phenolic compounds, such as hydroxytyrosol, usually grouped under the rubric “polyphenols”. The antioxidant and enzyme-modulating activities of extra virgin olive oil phenolics, such as their ability to inhibit NF-kB activation in human monocyte/macrophages has been demonstrated in vitro. There is also solid evidence that extra virgin olive oil phenolic compounds are absorbed and their human metabolism has been elucidated. Several activities that might be associated with cardiovascular protection, such as inhibition of platelet aggregation and reduction of plasma rHcy have been demonstrated in vivo. The biologically relevant properties of olive phenolics are described, although further investigations in controlled clinical trials are needed to support the hypothesis that virgin olive oil consumption may contribute to lower cardiovascular mortality.
Influence of CYP2C9 and CYP2C19 genetic polymorphisms on warfarin maintenance dose and metabolic clearance (2002)

CYP2C9 genetic polymorphisms markedly influence warfarin dose requirements and metabolic clearance of the S-warfarin enantiomer, although nongenetic factors may also contribute to their large interindividual variability.

The research journey was the focus of NTEU Deakin Branch Bluestocking Week event. National President Jeannie Rea opened the seminar 'Deakin women as supervisors and PhD students: Equity, Diversity, Difference and Respect in our relationships with each other and our research participants.' She noted the critical importance of gender research and the contribution of feminist research methodologies to qualitative research.
Essential immunologic orchestrators of intestinal homeostasis (2018)

Over the past 25 years, substantial advances have been made in our understanding of the cellular and molecular pathways that are essential to maintain a state of health in the mammalian gastrointestinal tract, an organ that is densely colonized by both immune cells and trillions of microbes. Seminal studies in the 1990s identified that several cytokines, antigen-presentation molecules, and components of the T cell receptor were necessary to prevent the development of spontaneous intestinal inflammation in mice. Subsequent research revealed that these pathways orchestrate beneficial interactions with intestinal microbes, involve complex communication between innate and adaptive immune cells, and can be dysregulated in human inflammatory bowel disease. Here, we discuss how these early findings set the stage for numerous other advances and shaped our current knowledge of host-microbiota interactions and intestinal homeostasis in mammals. It is expected that continued investigation of these areas will define previously unknown immunologic mechanisms of tolerance and inflammation in the intestine that can be exploited to benefit human health.
Etching characteristics of SrBi2Ta2O9 film with Ar/CHF3 plasma (2000)

Among the ferroelectric thin films that have been widely investigated for ferroelectric random access memory (FRAM) applications, the SrBi2Ta2O9 (SBT) thin film is appropriate as a memory capacitor material due to its excellent fatigue endurance. However, very few studies on the etch properties of SBT thin films have been reported, even though dry etching is an area that demands a great deal of attention in the very-large-scale integration of ferroelectric thin-film capacitors for FRAM applications. In this study, SrBi2Ta2O9 thin films were etched using a magnetically enhanced inductively coupled Ar/CHF3 plasma. Etch properties, such as etch rate, selectivity, and profile, were measured for different gas mixing ratios of CHF3/(Ar+CHF3), while the other process conditions were fixed at rf power of 600 W, dc-bias voltage of −150 V, and chamber pressure of 5 mTorr. The maximum etch rate of SBT thin films was 1650 Å/min under CHF3/(Ar+CHF3) of 0.1. Selectivities of SBT to Pt and photoresist masks were 1.35 and 0.94, respectively. The chemical reaction and compositional change of the etched surfaces were investigated by x-ray photoelectron spectroscopy analysis. The Sr and Ta atoms of SBT films react with fluorine; Sr–F and Ta–F are then removed by physical sputtering by Ar ions. The surface of a SBT film etched with CHF3/(Ar+CHF3)=0.1 was analyzed using secondary ion mass spectrometry. Scanning electron microscopy was used to examine etched profiles of SBT thin films. The wall angle of a SBT film etched using CHF3/(Ar+CHF3)=0.1 was approximately 85°.
The Antibacterial Effect of Qutran (wood Tar) from Olive Trees on Pathogenic Bacteria (2014)

Amongst the folklore medicine in Saudi Arabia, the tar preparation which is locally known as Qutran comes from various trees and has been used for a number of ailments in humans as well as in animals. This product is commercially produced and marketed in local shops selling herbs or herbal products but the source of this product is not mentioned. Three Gram positive and two Gram negative bacteria were exposed to various concentrations of Qutran and the growth inhibition was determined by the disk and agar diffusion method and enumeration of colony forming units by micro-dilution procedure. Both the Gram positive and Gram negative microorganisms showed a great sensitivity in terms of reduction in colony forming unit counts (CFU). Disk and agar diffusion assays showed a phenomenal inhibition of bacterial growth to Gram positive but lesser inhibition of bacterial growth in Gram negative bacteria. It was observed by the enumeration of CFU counts that the Qutran exerts more growth inhibition (killing effect) on Gram positive microorganisms than onto Gram negative bacteria.  This effect could be taken as action on the mucopeptide content of Gram positive bacteria than its presence in the trilaminar cell walls of Gram negative bacteria. The minimal biocidal activity (MBC) of Qutran towards the Gram positive microorganisms tested was determined as ≤0.625mg/ml, while the Gram negative microorganisms showed no growth above 1.25mg/ml.
Cascade Region Proposal Networks for Object Detection in the Wild (2019)

Although significant progresses have been made in object detection on common benchmarks (i.e., Pascal VOC), object detection in the wild is still challenging due to the serious data inadequacy and imbalance. To address this challenge, we construct a cascade framework which consists of multiple region proposal networks, referred to as C-RPNs. The essence of C-RPNs is adopting multiple stages to mine hard samples and learn better classifiers. Meanwhile, a feature chain and a score chain are proposed to help learning more discriminative representations for proposals. Moreover, a loss function of cascade stages is designed to train cascade classifiers through backpropagation. Our newly proposed object detection method is evaluated on Pascal VOC and a challenging dataset of littoral birds named BSBDV 2017. Our method outperforms baseline by an obvious margin, validating its efficacy for detection in the wild.
Genomics as the key to unlocking the polyploid potential of wheat (2015)

Polyploidy has played a central role in plant genome evolution and in the formation of new species such as tetraploid pasta wheat and hexaploid bread wheat. Until recently, the high sequence conservation between homoeologous genes, together with the large genome size of polyploid wheat, had hindered genomic analyses in this important crop species. In the past 5 yr, however, the advent of next-generation sequencing has radically changed the wheat genomics landscape. Here, we review a series of advances in genomic resources and tools for functional genomics that are shifting the paradigm of what is possible in wheat molecular genetics and breeding. We discuss how understanding the relationship between homoeologues can inform approaches to modulate the response of quantitative traits in polyploid wheat; we also argue that functional redundancy has 'locked up' a wide range of phenotypic variation in wheat. We explore how genomics provides key tools to inform targeted manipulation of multiple homoeologues, thereby allowing researchers and plant breeders to unlock the full polyploid potential of wheat.
Computing Traversal Times on Dynamic Markovian Paths (2013)

In source routing, a complete path is chosen for a packet to travel from source to destination. While computing the time to traverse such a path may be straightforward in a fixed, static graph, doing so becomes much more challenging in dynamic graphs, in which the state of an edge in one time slot (i.e., its presence or absence) is random, and may depend on its state in the previous time step. The traversal time is due to both time spent waiting for edges to appear and time spent crossing them once they become available. We compute the expected traversal time (ETT) for a dynamic path in a number of special cases of stochastic edge dynamics models, and for three edge failure models, culminating in a surprisingly challenging yet realistic setting in which the initial configuration of edge states for the entire path is known. We show that the ETT for this "initial configuration" setting can be computed in quadratic time, by an algorithm based on probability generating functions. We also give several linear-time upper and lower bounds on the ETT.
Monodispersed tantalum disulfide and adsorption complexes with cations (1975)

Cathodic electrolysis of 2H⋅⋅⋅TaS2 in a dilute sulfuric acid electrolyte results in intercalation of hydrogen and water. The water content increases as the ionic strength of the electrolyte is decreased. Addition of neutral surfactants (1%−10% Triton X−705 or glycerol) followed by high−speed stirring gave TaS2 layers monodispersed in the aqueous surfactant. Electronic absorption spectra of the dispersions agree well with spectra of cleaved solids. Dyes were used to study adsorption on the layers. Only cationic dyes were adsorbed and the adsorption was determined to be due to an ion exchange reaction with protons. Solid adsorption complexes were prepared by ultracentrifugation of the dispersion or by adding dyes to undispersed, water swollen TaS2. The solid adsorption complexes gave no x−ray powder patterns, and were deficient in sulfur. Ac susceptibility measurements did not indicate bulk superconductivity in any of the complexes. Electron transfer from the TaS2 layers to reducible dyes was observed, the apparent reduction potential being 0.25 V vs NHE.
Free Amino Acids in the Cerebrospinal Fluid of Epileptic Subjects (1974)

Summary The content of free amino acids in the cerebrospinal fluid of 10 epileptic patients was determined by ion exchange chromatography and compared with that in eight normal subjects. The content of glutamic acid was greatly diminished in epileptic patients in agreement with other findings in brain of epileptic animals and man. Otherwise no difference was found between the two groups, contrary to other reports of impaired amino acid metabolism in epilepsy. RÉsumé Le taux d'aminoacides Iibres dans le LCR de 10 épileptiques était déterminé par la méthode de chromatographic par échange d'ion, et comparé avec celui de 8 sujets normaux. Le taux d'acide glutamique était diminué chez ces sujets épileptiques, ceci en accord avec les dernières découvertes sur le cerveau des personnes et des animaux épileptiques. A part cela, aucune différence n'a été mise en évidence entre les deux groupes, contrairement aux anomalies trouvées par d'autres dans le métabolisme des aminoacides chez les épileptiques.

Labelling primary immune cells using bright blue fluorescent nanoparticles (2020)

Tracking cell movements is an important aspect of many biological studies. Reagents for cell tracking must not alter the biological state of the cell and must be bright enough to be visualized above background autofluorescence, a particular concern when imaging in tissue. Currently there are few reagents compatible with standard UV excitation filter sets (e.g. DAPI) that fulfill those requirements, despite the development of many dyes optimized for violet excitation (405 nm). A family of boron-based fluorescent dyes, difluoroboron β-diketonates, has previously served as bio-imaging reagents with UV excitation, offering high quantum yields and wide excitation peaks. In this study, we investigated the use of one such dye as a potential cell tracking reagent. A library of difluoroboron dibenzoylmethane (BF2dbm) conjugates were synthesized with biocompatible polymers including: poly(l-lactic acid) (PLLA), poly(ε-caprolactone) (PCL), and block copolymers with poly(ethylene glycol) (PEG). Dye-polymer conjugates were fabricated into nanoparticles, which were stable for a week at 37 °C in water and cell culture media, but quickly aggregated in saline. Nanoparticles were used to label primary splenocytes; phagocytic cell types were more effectively labelled. Labelling with nanoparticles did not affect cellular viability, nor basic immune responses. Labelled cells were more easily distinguished when imaged on a live tissue background than those labelled with a commercially available UV-excitable cytoplasmic labelling reagent. The high efficiency in terms of both fluorescence and cellular labelling may allow these nanoparticles to act as a short-term cell labelling strategy while wide excitation peaks offer utility across imaging and analysis platforms.
Hardware trust implications of 3-D integration (2010)

3-D circuit-level integration is a chip fabrication technique in which two or more dies are stacked and combined into a single circuit through the use of vertical electroconductive posts. Since the dies may be manufactured separately, 3-D circuit integration offers the option of enhancing a commodity processor with a variety of security functions. This paper examines the 3-D design approach and provides an analysis concluding that the commodity die system need not be independently trustworthy for the system of joined dies to provide certain trustworthy functions. In addition to describing the range of possible security enhancements (such as cryptographic services), we describe the ways in which multiple-die subsystems can depend on each other, and a set of processing abstractions and general design constraints with examples to address these dependencies.
Optimization and validation of organochlorine compounds in adipose tissue by SPE‐gas chromatography (2012)

Scientific evidence has shown an association between organochlorine compounds (OCC) exposure and human health hazards. Concerning this, OCC detection in human adipose samples has to be considered a public health priority. This study evaluated the efficacy of various solid-phase extraction (SPE) and cleanup methods for OCC determination in human adipose tissue. Octadecylsilyl endcapped (C₁₈-E), benzenesulfonic acid modified silica cation exchanger (SA), poly(styrene-divinylbenzene (EN) and EN/RP₁₈ SPE sorbents were evaluated. The relative sample cleanup provided by these SPE columns was evaluated using gas chromatography with electron capture detection (GC-ECD). The C₁₈-E columns with strong homogenization were found to provide the most effective cleanup, removing the greatest amount of interfering substance, and simultaneously ensuring good analyte recoveries higher than 70%. Recoveries > 70% with standard deviations (SD) < 15% were obtained for all compounds under the selected conditions. Method detection limits were in the 0.003-0.009 mg/kg range. The positive samples were confirmed by gas chromatography coupled with tandem mass spectrometry (GC-MS/MS). The highest percentage found of the OCC in real samples corresponded to HCB, o,p'-DDT and methoxychlor, which were detected in 80 and 95% of samples analyzed respectively.
Reduced Interleukin‐12 and Transforming Growth Factor–β1 in Severe Childhood Malaria: Relationship of Cytokine Balance with Disease Severity (2000)

Interleukin (IL)-12 and transforming growth factor (TGF)-beta1 regulate the balance between pro- and anti-inflammatory cytokines in animal models of malaria. Since the cytokine balance may be an important determinant of whether a protective or a pathogenic immune response develops, plasma cytokine ratios were examined in Gabonese children with various degrees of malarial severity. Severe disease was characterized by high-density parasitemia and severe anemia. IL-12 and TGF-beta1 were significantly lower, whereas tumor necrosis factor (TNF)-alpha and IL-10 were significantly higher in children with severe malaria. The ratios of TGF-beta1/IL-12 and IL-10/IL-12 were significantly higher in the severe, compared with the mild, malaria group. In contrast, ratios of TGF-beta1/TNF-alpha and IL-10/TNF-alpha were significantly lower in the severe malaria group. These results suggest that the inflammatory cascade in severe malaria is characterized by suppression of the protective effects of TGF-beta1 and IL-12, and that overproduction of TNF-alpha may promote deleterious effects, such as severe anemia.
