Direction of arrival tracking of an underwater acoustic source using particle filtering: Real data experiments (2013)

In the past, both theoretical work and practical implementation of particle filtering (PF) method have been extensively studied. However, its application in underwater signal processing has received much less attention. This paper intends to introduce PF approach for underwater acoustic signal processing. Particularly, we are interested in direction of arrival (DOA) estimation using PF. A detailed introduction along with this perspective is presented in this paper. Since the noise usually spreads the mainlobe of likelihood function and causes problem in subsequent particle resampling step, an exponential weighted likelihood model is developed to emphasize particles at more relevant area. Hence, the the effect due to background noise can be reduced. Real underwater acoustic data collected in SWELLEx-96 experiment are employed to demonstrate the performance of the proposed PF approaches for underwater DOA tracking.
Novel vitamin E derivative with 4‐substituted resorcinol moiety has both antioxidant and tyrosinase inhibitory properties (2001)

A novel vitamin E derivative, (6"-hydroxy-2",5",7",8"-tetramethylchroman-2"-yl)methyl 3-(2',4'-dihydroxyphenyl)propionate (TM4R), which has a chromanoxyl ring and 4-substituted resorcinol moieties, was synthesized; and its inhibitory effects on tyrosinase, antioxidant ability, and lightening effect of ultraviolet B (UVB)-induced hyperpigmentation were estimated. TM4R showed potent inhibitory activity on tyrosinase, which is the rate-limiting enzyme in melanogenesis. The scavenging activities of TM4R on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were found to be nearly the same as those of alpha-tocopherol. Furthermore, an efficient lightening effect was observed following topical application of TM4R to UVB-stimulated hyperpigmented dorsal skin of brownish guinea pigs. These results suggest that TM4R may be a candidate for an efficient whitening agent, possibly by inhibiting tyrosinase activity and biological reactions caused by reactive oxygen species.
Tight-binding approach to time-dependent density-functional response theory (2001)

In this paper we propose an extension of the self-consistent charge-density-functional tight-binding (SCC-DFTB) method [M. Elstner et al., Phys. Rev. B 58, 7260 (1998)], which allows the calculation of the optical properties of finite systems within time-dependent density-functional response theory (TD-DFRT). For a test set of small organic molecules low-lying singlet excitation energies are computed in good agreement with first-principles and experimental results. The overall computational cost of this parameter-free method is very low and thus it allows us to examine large systems: we report successful applications to ${\mathrm{C}}_{60}$ and the polyacene series.
PROBES: a framework for probability elicitation from experts. (1999)

A decision analytic model represents uncertainties as probability distributions. These distributions are hard to assess especially for large and dynamic models. We propose an integrated framework that facilitates elicitation of the relevant probability distributions for dynamic decision models from the domain experts. The experts usually use some judgmental heuristics to aid probability assessments; the resulting distributions may be proned to cognitive biases. Our framework aims to minimize the effects of these biases and to improve the quality of decisions made. We have implemented a prototype system of the framework and evaluated its effectiveness via a case study in the follow-up management of colorectal cancer patients after curative surgery. Preliminary results demonstrate the practical promise of the framework.
Affinity chromatography purification of type A botulinum neurotoxin from crystalline toxic complex (1978)

Type A botulinum neurotoxin was purified from toxic crystals by adsorption to p-aminophenyl-beta-D-thiogalactopyranoside coupled to CH-Sepharose 4B. At pH 6.3, the toxic complex was held by the binding between the ligand and the hemagglutinin of the complex; the toxin is eluted selectively by dissociating the complex with buffer-saline of pH 7.9. The single-step affinity chromatography recovered 50 to 60% of applied toxicity as preparations of greater than 99% purity.
Towards hybrid driver state monitoring: Review, future perspectives and the role of consumer electronics (2016)

The purpose of this paper is to bring together multiple literature sources which present innovative methodologies for the assessment of driver state, driving context and performance by means of technology within a vehicle and consumer electronic devices. It also provides an overview of ongoing research and trends in the area of driver state monitoring. As part of this review a model of a hybrid driver state monitoring system is proposed. The model incorporates technology within a vehicle and multiple brought-in devices for enhanced validity and reliability of recorded data. Additionally, the model draws upon requirement of data fusion in order to generate unified driver state indicator(-s) that could be used to modify in-vehicle information and safety systems hence, make them driver state adaptable. Such modification could help to reach optimal driving performance in a particular driving situation. To conclude, we discuss the advantages of integrating hybrid driver state monitoring system into a vehicle and suggest future areas of research.

Demonstration of Surfactant Flooding of an Alluvial Aquifer Contaminated with Dense Nonaqueous Phase Liquid (1999)

Two field tests at Hill Air Force Base Operational Unit 2 were completed in May and September of 1996 to demonstrate surfactant remediation of an alluvial aquifer contaminated with DNAPL (dense nonaqueous phase liquid). The DNAPL at Hill OU2 consists primarily of trichloroethene (TCE), 1,1,1-trichloroethane (1,1,1-TCA) and tetrachloroethene (PCE). Sheet piling or other artificial barriers were not installed to isolate the 6.1 x 5.4 m test area from the surrounding aquifer. Hydraulic confinement was achieved by: (1) injecting water into a hydraulic control well south of the surfactant injectors (2) designing the well pattern to take advantage of the alluvial channel confined below and to the east and west by a thick clay aquiclude and (3) extracting at a rate higher than the injection rate within the well pattern. An extensive program of laboratory experimentation, hydrogeological characterization, effluent treatment and predictive modeling was critical in the design of these tests and the success of the project. Simulations were conducted to determine test design variables such as well rates, injected chemical amounts and test duration, and to predict the recovery of contaminants and injected chemicals, degree of hydraulic confinement and pore volume of the aquifer swept by the injected fluids. Partitioning interwell tracer tests were used to estimate the volume and saturation of DNAPL in the swept volume and to assess the performance of the surfactant remediation. Analysis of the Phase I and Phase II results showed high recoveries of all injected chemicals, indicating that hydraulic confinement was achieved without sheet pile boundaries. Approximately 99% of the DNAPL within the swept volume was removed by the surfactant in less than two weeks, leaving a residual DNAPL saturation of about 0.0003. The concentration of dissolved contaminants was reduced from 1100 mg/l to 8 mg/l in the central monitoring well during the same time period.
Post‐Metallocene Hydridolanthanide Chemistry: [Lu{(Me<sub>3</sub>Si)<sub>2</sub>NC(NiPr)<sub>2</sub>}<sub>2</sub>(μ‐H)]<sub>2</sub> — A Novel Lanthanide Hydride in a Non‐Cyclopentadienyl Coordination Environment; Synthesis, Structure and Catalytic Activity in Olefin Polymerization (2004)

Abstract The reaction of anhydrous LuCl 3 with a twofold molar excess of lithium guanidinate [Li{(Me 3 Si) 2 NC(N i Pr) 2 }], obtained in situ from the amide [LiN(SiMe 3 ) 2 (Et 2 O)] and 1,3‐diisopropylcarbodiimide in THF, yields the bis(guanidinate) “ate” complex [Lu{(Me 3 Si) 2 NC(N i Pr) 2 } 2 (μ‐Cl) 2 Li(THF) 2 ] ( 1 ). The alkyllutetium derivative [Lu{(Me 3 Si) 2 NC(N i Pr) 2 } 2 (CH 2 SiMe 3 )] ( 2 ) was synthesized by a metathesis reaction of 1 with LiCH 2 SiMe 3 in toluene. The treatment of 2 with an equimolar amount of PhSiH 3 in hexane at room temperature results in the first known dimeric lanthanide hydride in a bis(guanidinate) coordination environment, [Lu{(Me 3 Si) 2 NC(N i Pr) 2 } 2 (μ‐H)] 2 ( 3 ). The crystal structures of complexes 1 and 3 have been determined by X‐ray crystallography. The hydrido complex 3 was found to catalyze polymerization of ethylene, propylene and styrene.

Detection Rate of <sup>18</sup>F-Fluorethylcholine-PET/CT in relation to PSA Value in PCA Patients Referred with Biochemical Relapse (2020)

Attempts to predict the likelihood of positive morphological imaging related with PSA value in patients referred with biochemical recurrence were the focus of many studies. Using nuclear medicine modalities, numerous studies likewise had been performed for the same purpose, however mostly using C-11-labeled choline. For this purpose, we selected 193 prostate cancer patients from our database between 2006 and 2010. They had been referred to our department to undergo <sup>18</sup>F-fluorethylcholine (FECH)-PET/CT due to biochemical recurrence after potentially curative procedures. As a result, in 84 out of 193 patients, <sup>18</sup>F-FECH-PET demonstrated positive findings with an overall detection rate of 44%. Statistically, there was a significant difference in PSA values in positive findings vs. negative findings (<i>p</i> < 0.001), and there was a linear correlation between the detection rate and PSA value (<i>r</i> = 0.91). Moreover, there was a relation between initial therapy and recurrence type. So, the local relapse was the most frequent recurrence (>70%) after radiation therapy alone. By contrast, patients after radical prostatectomy followed by salvage radiotherapy showed a low likelihood of local recurrence. In conclusion, PSA value was confirmed to have a determinant role in <sup>18</sup>F-FECH-PET outcome. Moreover, there was a link between recurrence type and initial therapy, which-if prospectively confirmed-may play a guiding role in selecting the appropriate diagnostic methods.
Metabolic Therapeutics in Angina Pectoris: History Revisited with Perhexiline (2006)

The ever-increasing burden of ischaemic heart disease and its common manifestation chronic angina pectoris calls for the exploration of other treatment options for those patients who despite the maximum conventional pharmacological and surgical interventions continue to suffer. Such exploration has led to the increasing use of new metabolically acting antianginal agents and the re-emergence of an old and somewhat forgotten pharmacological agent, perhexiline maleate. This review aims to update the cardiac nurse with knowledge to manage the care a patient receiving perhexiline maleate treatment and provide a brief review of three new metabolic agents: trimetazidine, ranolazine and etomoxir.
Ultrasonic Culvert Thickness Determination. (1995)

Abstract : This work describes a response to the need for a practical nondestructive method of measuring the thickness of culverts in situ established at the New York State Department of Transportation. The proposed method will provide data to realistically evaluate the remaining safe lives of the culverts. The technique developed uses the ultrasonic pulse echo technique with commercial off the shelf ultrasonic equipment and piezoelectric transducers in a bubbler configuration. The equipment consists of the 25DL precision thickness gage and the B 120 bubbler with V316-B, 0.75-inch PTF, 20MHz transducer--all by Panametrics. The user has to add a small water pump to provide continuous stream of water and a hollowed out rubber stopper to ease application of the bubbler to the culvert surface.
Fabrication of a heterostructural fibrillated collagen matrix for the regeneration of soft tissue function (2011)

Most collagen matrices used in tissue engineering and regenerative medicine are gels or sponges. Our goal is to prepare an artificial extracellular matrix (ECM) that possesses similar structure to the native ECM of soft tissue in order to replicate its physical and biological properties. Here, we report the preparation of collagen matrices with fibrillated structures based on the fibrillogenesis/gelling method. We focused on regenerating the function of native ECM of soft tissues by creating a multifunctional collagen. A collagen matrix is a sponge/gel composite structure which allows the cell to infiltrate only on one side of the matrix without shrinkage. This results in healing and regeneration of the tissue surrounding the matrix, similar to the native ECM in which cell infiltration occurs from one side during implantation. Furthermore, high mechanical strength can prevent deformation or shrinkage, and decelerate the degradation during the early phase of implantation, which eventually cause device failure.

Objective: To discover the mechanism of Jianshenqigong·wuqinxi on subheath mental problems, we observe the effects of practicing Jianshenqigong-wuqinxi on subhealth mental problems including depression, anxiety, and memory loss. Methods: (1) 80 cases with subhealth problem were randomly divided into two groups. 40 cases practicing Jianshenqigong-wuqinxi were used as test group, and the other 40 unpracticing cases were used as control group. (2) The test group was practising Jianshenqigong-wuqinxi one hour in the morning five times per week for three months. (3) Scores of subhealth status such as depression and anxiety were evaluated once every two weeks, while the memory test was performed once a month. (4) Data analysis: SPSS11.0 software was used for statistical analyses. Data were shown in mean ± SEM. Difference was considered significant if the t-test P value is less than 0.05. Results: (1) Scores of subhealth state and depression were significantly lower in test group than that those of control group. The beneficial effects of practicing Jianshenqigong-wuqinxi were more obvious for the subjects in the test group whol had practiced Jianshenqigong-wuqinxi for two to twelve weeks (P<0.05). (2) Scores of anxiety test were significantly lower in test group than that of control group after practicing Jianshenqigong-wuqinxi for six to twelve weeks (P<0.05). (3) Scores of memory were significantly higher in test group than that of control group (P<0.05). Conclusions: (1) Practicing Jianshenqigong-wuqinxi could promote health in people who have subhealth mental problems. (2) Practicing Jianshenqigong·wuqinxi could relieve depression, anxiety while enhance memory.
SIRUS: A mobile robot for Floating Production Storage and Offloading (FPSO) ship hull inspection (2008)

This paper describes the current development status of a mobile robot designed to inspect the outer surface of large oil ship hulls and Floating Production Storage Offloading (FPSO) platforms. These are usually former oil tanker ships, especially adapted to work as an oil offshore platform. Several mechanisms of corrosion are present in such structures, worsen by the abnormal static operation regime of the vessel and other causes. This situation requires a detailed program of inspection, using several Non Destructive Detection (NDT) techniques, operated manually. Here, a robotic crawler designed to perform such inspections is presented. Locomotion over the hull is provided trough a pair or DC-Motor propelled magnetic tracks, while the system is controlled by two networked PCs and a set of custom hardware to drive the motors, video cameras, ultrasound (US), inertial platform and other devices. Navigation is provided by a Extended Kalman Filter sensor fusion formulation, integrating hodometry and inertial sensors. The current version of the prototype is able to perform ultrasound thickness measurements in the dry part of the hull.
Locality-driven MRC Construction and Cache Allocation (2018)

Flash caches have been widely deployed in cloud computing environments to boost the performance of virtual machines (VMs), but they are usually oversubscribed among the VMs due to the limited cache space compared to the VMs' working set (WS) size, making the cache allocation a challenging problem. Miss Ratio Curves (MRCs) can be used to manage cache partitioning among the VMs; however, traditional WS-based MRCs are constructed based on all the data, including the data without good locality, which forces the VMs to allocate unnecessary cache space to achieve their objective performance. The paper presents QCache, a locality-driven solution for MRC construction and cache allocation. First, it proposes a new design of MRC, RWS-based MRCs, which is constructed based on the reuse working set and guides the cache allocation based on the good-locality data. Second, with RWS-based MRCs, it provides two different algorithms to optimize the cache allocation among all the VMs, regarding the improvement of the overall performance and the optimization for each VM's Quality-of-Service respectively.

Characterization of the chicken oocyte receptor for low and very low density lipoproteins. (1987)

The chicken oocyte receptor for low and very low density lipoproteins has been identified and characterized. Receptor activity present in octyl-beta-D-glucoside extracts of oocyte membranes was measured by a solid phase filtration assay, and the receptor was visualized by ligand blotting. The protein had an apparent Mr of 95,000 in sodium dodecyl sulfate-polyacrylamide gels under nonreducing conditions and exhibited high affinity for apolipoprotein B-containing lipoproteins, but not for high density lipoproteins or lipoproteins in which lysine residues had been reductively methylated. Binding of lipoproteins was sensitive to EDTA, suramin, and treatment with Pronase. In these aspects, the avian oocyte system was analogous to the mammalian low density lipoprotein receptor in somatic cells. Furthermore, a structural relationship between the mammalian and avian receptors was revealed by immunoblotting: polyclonal antibodies directed against the purified bovine low density lipoprotein receptor reacted selectively with the 95-kDa chicken receptor present in crude oocyte membrane extracts.
Robust interactive image segmentation with automatic boundary refinement (2010)

We propose an effective image segmentation approach with a novel automatic boundary refinement procedure that requires little user interaction and makes the object cutout process more robust and convenient. It achieves these goals by the following three steps. First, merge over-segmented regions according to the maximal similarity rule using a few marking strokes as input. Second, detect possible erroneous low-contrast object boundaries by analyzing image content. Third, automatically refine those boundary regions using both local and global information. Experimental results are good even on very complex images.
Entropy and multiscale analysis: a new feature extraction algorithm for aerial images (2002)

This paper presents a new, fully automatic and robust feature extraction algorithm based on the selection of a given range of scales. It compares consecutive band-pass images of a Gaussian multiscale decomposition to extract the objects that appear between given scales. The comparison is performed using original distributed entropy measures. The application to building detection in aerial images shows that scale is a robust and precise criterion for the detection of man-made objects. They also show that distributed entropic tools are relevant for the comparison of band-pass images. From a more theoretical point of view, this method stands between the scale-space and wavelet approaches. It tries to infer the geometrical concept of scale found in the scale-space theory into the algebraic scale of the wavelet theory.
Research on Improvement of Performance of Anemometer Using PTC Thermistor (2000)

An anemometer employing the bulk PTC thermistor as the sensing element is investigated in this study. The numerical and experimental works are carried out to improve the sensitivity problem of the element by focusing fluid dynamics point of view. The typical shape of the sensing element has been used as a rectangular type, but this shape has a sensitivity problem because of flow separations on the sharp edge when the flow direction is different from that of the sensing element. In order to reduce the reading error, the installer has to be very careful about the flow direction. The reading error fluctuation by time as well as the sensitivity problem can be improved considerably through this study. It can be concluded that the small change of the sensor shape can improve the performance of the flow sensor.
Transforming the Economy (2020)

The global ecological crisis poses much greater risks to humanity than Covid-19. At the same time, the pandemic provides a unique opportunity for governments to pursue a ‘greener’ and more sustainable future, for example through large-scale investments in clean energy sources, energy efficiency, waste reduction technologies, climateresilient infrastructure, regenerative agriculture and biodiversity protection. Yet, despite the urging of leading economists, ecologists and investors, measures to enhance ecological sustainability have not been prioritised in most governmental fiscal and regulatory responses to the pandemic. This article briefly summarises the nature of the current ecological crisis and, with particular reference to New Zealand, the policy measures required for an effective response. Fundamentally, a step change is needed from the current linear economy (based on finite energy sources and other non-renewable natural resources) to a more circular economy (based on renewable energy sources, the minimisation of waste and the efficient use of natural resources).
