Affine estimation via region expansion (2014)

In this work, we present a novel method for accurate affine transformation estimation of image regions. We illustrate the benefits of using such a method in a point matching mechanism that enables locating large amount of point matches with high geometric precision and low rate of false matches. Recent publications have shown that considering the affine transformation model of local regions, is extremely beneficial for the purpose of point matching. Yet, those methods are not used extensively for two reasons. First, because they are computationally more demanding, second reason is that the estimation of the Affine transformations are of limited accuracy and therefore the usage of them is limited. We propose a region expansion method, based on accurate estimation of the affine transformation, that is proven to accurately predict locations beyond the initial local regions. We also prove that expansion beyond local regions is crucial for getting much more accurate transformation estimations. Finally, by reducing the amount of false matches considerably, we reduce the need for computationally demanding post processes.
Product chain analysis of three-dimensional imaging laser radar systems employing Geiger-mode avalanche photodiodes (2010)

Image chain analysis is a systems engineering tool which allows imaging system designers to understand how different
components of the imaging chain affect the quality and derivable information of generated data products. In this paper,
we apply image chain analysis techniques to formulate a product chain for airborne three-dimensional (3D) imaging
laser radar systems that employ arrays of Geiger-mode avalanche photodiode detectors. The processes involved in 3D
data generation and subsequent information extraction are described. These processes are grouped into five groups (Data
Capture, Raw Point Cloud Formation, Noise Filtering, Advanced Post-Processing and Data Analysis) to form the
proposed product chain. For each group, key parameters that affect 3D data quality are identified along with synthetic
data examples of their respective impact to 3D data quality and information extraction. In addition, we discuss on-going
and future work intended to continue our understanding o3 3D data quality and interpretability.
RouteBricks (2009)

We revisit the problem of scaling software routers, motivated by recent advances in server technology that enable high-speed parallel processing--a feature router workloads appear ideally suited to exploit. We propose a software router architecture that parallelizes router functionality both across multiple servers and across multiple cores within a single server. By carefully exploiting parallelism at every opportunity, we demonstrate a 35Gbps parallel router prototype; this router capacity can be linearly scaled through the use of additional servers. Our prototype router is fully programmable using the familiar Click/Linux environment and is built entirely from off-the-shelf, general-purpose server hardware.
Do Cancer Drugs Counteract Neurodegeneration? Repurposing for Alzheimer’s Disease (2016)

In spite of in depth investigations in the field of the amyloid cascade hypothesis, so far, no disease modifying therapy has been developed for Alzheimer's disease (AD). The pathophysiology provides some evidence of the inverse correlation between cancer and AD. Both AD and cancer are characterized by abnormal cellular behaviors; trigger factors along with a meta synchronously action is expected to drive cancer or neurodegeneration, supporting, respectively, progressive neuronal loss or uncontrolled cell proliferation in cancer cells. So far, cancer and AD are seemingly two opposite ends of the same biological spectrum. Basic science increasingly indicates shared molecular mechanisms between cancer and AD and gives weight to key relevant biological theories; according to them, the inverse tuning of clustered gene expression, the sharing of mutual independent pathway or the deregulated unfolded proteins system (UPR) may count for this inverse association. Additionally, the common biological background gave credibility to the recent discovery of a repurposing role for cancer drugs in AD. It refers to the development of new uses for existing pharmaceuticals having the same role as the original mechanism or to the discovery of a new drug action with disease modifying effects. The present review summarizes the most important biological theories that link neurodegeneration and cancer and provides an up-to-date revision of the repurposing cancer agents for AD. The review also addresses the gap of knowledge, since drug cancer repositioning holds an important promise but further investigations are warranted to ascertain the clinical relevance of such attractive clinical candidate compounds for AD.
The Dielectric Barrier Discharge: A Bright Spark for Australia's Future (1995)

A dielectric barrier or silent discharge is the name given to a transient gas discharge occurring between two electrodes separated by one or two layers of dielectric material. They have formed the basis of commercial ozonisers for nearly a century but, despite the maturity of this technology, significant experimental and theoretical questions remain to be answered about the operation of these discharges before they can be fully exploited in new applications. Of particular interest is the potential that dielectric barrier discharges display for development as sources of intense, monochromatic, incoherent UV/VUV radiation. This paper briefly outlines the current status of the field with regard to research into the operation and UV/VUV radiative spectroscopy of dielectric barrier discharges. Some applications of these sources are briefly discussed and some of the theoretical models proposed to explain their operation are outlined. The paper concludes with a summary and outlook of the experimental and theoretical project that is being set up under a collaborative venture by CQU and ANU to study dielectric barrier discharges.

Nitric Oxide Mediates Cerebral Ischemic Tolerance in a Neonatal Rat Model of Hypoxic Preconditioning (1999)

Neuroprotection against cerebral ischemia can be realized if the brain is preconditioned by previous exposure to a brief period of sublethal ischemia. The present study was undertaken to test the hypothesis that nitric oxide (NO) produced from the neuronal isoform of NO synthase (NOS) serves as a necessary signal for establishing an ischemia-tolerant state in brain. A newborn rat model of hypoxic preconditioning was used, wherein exposure to sublethal hypoxia (8% oxygen) for 3 hours renders postnatal day (PND) 6 animals completely resistant to a cerebral hypoxic-ischemic insult imposed 24 hours later. Postnatal day 6 animals were treated 0.5 hour before preconditioning hypoxia with the nonselective NOS inhibitor L-nitroarginine (2 mg/kg intraperitoneally). This treatment, which resulted in a 67 to 81% inhibition of calcium-dependent constitutive NOS activity 0.5 to 3.5 hours after its administration, completely blocked preconditioning-induced protection. However, administration of the neuronal NOS inhibitor 7-nitroindazole (40 mg/kg intraperitoneally) before preconditioning hypoxia, which decreased constitutive brain NOS activity by 58 to 81%, was without effect on preconditioning-induced cerebroprotection, as was pretreatment with the inducible NOS inhibitor aminoguanidine (400 mg/kg intraperitoneally). The protective effects of preconditioning were also not blocked by treating animals with competitive [3-(2-carboxypiperazin-4-yl)propyl-1-phosphonate; 5 mg/kg intraperitoneally] or noncompetitive (MK-801; 1 mg/kg intraperitoneally) N-methyl-D-aspartate receptor antagonists prior to preconditioning hypoxia. These findings indicate that NO production and activity are critical to the induction of ischemic tolerance in this model. However, the results argue against the involvement of the neuronal NOS isoform, activated secondary to a hypoxia-induced stimulation of N-methyl-D-aspartate receptors, and against the involvement of the inducible NOS isoform, but rather suggest that NO produced by the endothelial NOS isoform is required to mediate this profound protective effect.
Physics-based approach to chemical source localization using mobile robotic swarms (2008)

PD patients manifesting camptocormia are likely subjected to NMS than patients without camptocormia, especially autonomic and miscellaneous symptoms. These patients also suffered from more severe neuropsychiatric symptoms and sleep disorders.
A differential effect of visual cortex tDCS on reading of English and Chinese in patients with central vision loss (2022)

Abstract We report that visual cortex a-tDCS influences reading performance in individuals with macular degeneration differently depending on the writing system employed. This finding will help to guide the international development of vision rehabilitation programs for macular degeneration that may utilize non-invasive brain stimulation.
Optimized Differential Self-Inductance Displacement Sensor for Magnetic Bearings: Design, Analysis and Experiment (2017)

The miniaturization requirements have been put forward to the sensors for the development of the modern industry. However, the traditional inductive displacement sensor applied to active magnetic bearings (AMBs) has complicated detection device and measuring circuit with excessive discrete components which cannot meet the requirements of the miniaturization. To remedy the infliction, an optimized differential self-inductance displacement sensor was designed for AMBs. Concretely, the operating principle of the self-inductance displacement sensor was analyzed in detail. Then the optimized structure was proposed and the measuring circuit was designed. After the designing, the performance of the sensor was analyzed. Based on the analysis and designing, a series of experiments were carried out to test the performance. The results demonstrated that the designed sensor can realize higher linearity, higher sensitivity, and wider dynamic response range than the traditional inductive displacement sensor. And it is suitable to the AMBs system, with higher rotation speed and small volume.
Incremental entity fusion from linked documents (2014)

In many government applications, especially for intelligence and law-enforcement, we often find that information about entities, such as persons or even companies, are available in disparate data sources. For example, information distributed across passports, driving licences, bank accounts, and income tax documents that need to be resolved and fused to reveal a consolidated profile of an individual. In this paper we describe an algorithm to fuse documents that are highly likely to belong to the same entity by exploiting inter-document references in addition to attribute similarity. Our technique uses a combination of iterative graph-traversal, locality-sensitive hashing, iterative match-merge, and graph-clustering to discover unique entities based on a document corpus. Further, new sets of documents can be added incrementally while having to re-process only a small subset of a previously fused entity-document collection. We present performance and quality results via both Bayesian likelihood fusion as well as using Support Vector Machines to demonstrate benefit of using inter-document references, both to improve accuracy as well as for detecting attempts at deliberate obfuscation.
Integrated systems: subspecialists as capitated primary care physicians? (1993)

The shortage of primary care physicians, the shifting roles of specialists and abundance of subspecialists are challenging hospital alliances. In the new world of managed care and managed competition, where providers assume financial risk for overutilization, management must discard traditional measures of profitability and focus on adding value. Hospitals are taking steps to become accountable health partners in smaller to mid-sized markets (two or three hospitals) by sponsoring community based direct contracting managed care networks. This type of system helps providers offer employers a local managed care alternative that is better able to demonstrate quality of care, and to control utilization through capitation and other pricing strategies.

Exploitation of higher-order cyclostationarity for weak-signal detection and time-delay estimation (2003)

The cumulant theory of cyclostationary time-series is applied to several types of problems that arise in the area of signal interception and to the problem of estimating the relative time-delay of a heavily corrupted signal received at two locations. The theory characterizes the additive sine waves present in the output of nonlinear transformations of such time-series. The detection and time-delay estimation problems posed are difficult to solve because the signal is weak, the noise and interference are nonstationary and non-Gaussian, and the signal does not exhibit second-order cyclostationarity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Experimental study on combustion behavior of thermoplastics with different ventilation conditions (2011)

The aim of this paper is to investigate the effect of ventilation conditions on the combustion behavior of thermoplastics in enclosure. As is known,thermoplastics is of extremely unique advantages, such as easy in manufacturing,light in weight,cheap in production cost,waterproof as well as corrosion-resistant,all of which help to make it widely used in industry as well as in daily life.However,as most thermoplastics are flammable,great concern should be paid to the potential fire risk of its application in architectural buildings.As is reported,there exist wall fire and pool fire hazards plus the accelerated fire-spreading speed in the process of the thermoplastic fire. The combustion process is actually affected by many factors,such as ignition method,thickness of sample and ventilation condition.In our research,we have conducted a series of large-scale experiments on polypropylene sheets with thicknesses of 5 mm in ISO 9705 fire testing rooms with different ventilation conditions controlled.In addition,we have measured systematically fire dynamics parameters,such as the heat-releasing rate,CO concentration and temperature field,were. Repetitive experiments were completed in order to get useful data. Considering the differences between width and height of ventilation, we have put forward a non-dimensional parameter of height location. The experimental results we have gained show that ventilation condition plays a key role on peak HRR value,though the height variety may have greater effect than the width variety.The peak HRR value proves to be in linear form with the ventilation conditions,including the size and height of the ventilation.

Articles : Binding Substies in the active Site of Zn2+ Glycerophosphocholine cholinephsphodiesterase (1995)

The properties of binding sites in the active site of Zn^(2+)-glycerophosphocholine cholinephosphodiesterase were examined using substrates and inhibitors of the enzyme. Phosphodiesterase hydrolyzed p-nitrophenylphosphocholine, p-aminophenylphosphocholine, and glycerophosphocholine, but did not hydrolyze either acylated glycerophosphocholine or bis (p-nitrophenyl)phosphate, suggesting a size limitation for interaction with a glyceryl moiety-binding subsite. The hydrolysis of p-nitrophenylphosphocholine was competitively inhibited by glycerophosphocholine and p-aminophenylphosphocholine, while glycerophosphoethanolamine was a weak inhibitor. The enzyme was also inhibited by choline, but not by ethanolamine. Thiocholine, a much more potent inhibitor than choline, was more inhibitory than cysteamine, suggesting a strict specificity of an anionic subsite adjacent to a Zn^(2+) subsite. Of all oxyanions tested, the tellurite ion was found to strongly inhibit the enzyme by binding to a Zn^(2+) subsite. The inhibitory role of tellurite was synergistically enhanced by tetraalkylammonium salts, but not by glycerol. Deactivation of the enzyme by diethylpyrocarbonate was partially protected by choline, but not by glycerophosphate. It is suggested that the active site of phosphodiesterase contains three binding subsites.
Formation of the Ovarian Follicular Antrum and Follicular Fluid1 (2010)

The formation of the follicular antrum and follicular fluid has received scant attention from researchers, yet both are important processes in follicular development. The central hypothesis on follicular fluid formation suggests that production by granulosa cells of hyaluronan and the chondroitin sulfate proteoglycan versican generates an osmotic gradient. This gradient draws in fluid derived from the thecal vasculature. Inter-alpha-trypsin inhibitor is also present in follicular fluid at least in species with large follicles, and inter-alpha-trypsin inhibitor and versican could additionally bind or cross-link with hyaluronan, resulting in the retention of these molecules within the follicular antrum. Barriers to the movement of fluid across the membrana granulosa are apparently minimal, as even relatively large serum proteins are present in follicular fluid. Despite the relative permeability of the follicular wall, aquaporins are present in granulosa cells and could be actively involved in the transport of water into the follicle. The formation of an antrum also requires movement of granulosa cells relative to each other to allow the fluid to accumulate. This presumably involves remodeling of cell-cell junctions and in species with small follicles may involve death of centrally located granulosa cells. Remodeling of the stroma and thecal layers also accompanies growth and expansion of the antrum and presumably involves similar processes that accompany growth of other glands.
11β-HSD2 SUMOylation Modulates Cortisol-Induced Mineralocorticoid Receptor Nuclear Translocation Independently of Effects on Transactivation (2017)

The enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) has an essential role in aldosterone target tissues, conferring aldosterone selectivity for the mineralocorticoid receptor (MR) by converting 11β-hydroxyglucocorticoids to inactive 11-ketosteroids. Congenital deficiency of 11β-HSD2 causes a form of salt-sensitive hypertension known as the syndrome of apparent mineralocorticoid excess. The disease phenotype, which ranges from mild to severe, correlates well with reduction in enzyme activity. Furthermore, polymorphisms in the 11β-HSD2 coding gene (HSD11B2) have been linked to high blood pressure and salt sensitivity, major cardiovascular risk factors. 11β-HSD2 expression is controlled by different factors such as cytokines, sex steroids, or vasopressin, but posttranslational modulation of its activity has not been explored. Analysis of 11β-HSD2 sequence revealed a consensus site for conjugation of small ubiquitin-related modifier (SUMO) peptide, a major posttranslational regulatory event in several cellular processes. Our results demonstrate that 11β-HSD2 is SUMOylated at lysine 266. Non-SUMOylatable mutant K266R showed slightly higher substrate affinity and decreased Vmax, but no effects on protein stability or subcellular localization. Despite mild changes in enzyme activity, mutant K266R was unable to prevent cortisol-dependent MR nuclear translocation. The same effect was achieved by coexpression of wild-type 11β-HSD2 with sentrin-specific protease 1, a protease that catalyzes SUMO deconjugation. In the presence of 11β-HSD2-K266R, increased nuclear MR localization did not correlate with increased response to cortisol or increased recruitment of transcriptional coregulators. Taken together, our data suggests that SUMOylation of 11β-HSD2 at residue K266 modulates cortisol-mediated MR nuclear translocation independently of effects on transactivation.
CNN-based Camera Model Identification Using Image Noise in Frequency Domain (2019)

Camera model identification has been studied extensively within digital image forensics as a deterrence to secret photography and image forgery. The feasibility of convolutional neural networks (CNNs) has been proven for an image classification algorithm. CNN-based algorithms have been proposed for camera model classification, and they focus on training with image/noise in a spatial domain. However, because the periodic characteristics of image noise are one of the essential types of information for model classification, it is more efficient to train CNN models with image noise in a frequency domain. In this paper, we propose a CNN-based approach for camera model classification that trains a CNN model with high-frequency components of images in the frequency domain. In the experiments, we evaluated the accuracy of camera model/brand classification using a Dresden image dataset. We achieved 97.35% and 99.32% accuracy, respectively, for 14-model classification of 256×256 image patches and full images. Using this approach, our results indicated a 1.84% and 1.35% improvement, respectively, compared with a state-of-the-art method. We also achieved 100% accuracy for 10-brand classification.
