Ground-Edge-Based LIDAR Localization Without a Reflectivity Calibration for Autonomous Driving (2017)

In this work, we propose an alternative formulation to the problem of ground reflectivity grid-based localization involving laser-scanned data from multiple LIDARs mounted on autonomous vehicles. The driving idea of our localization formulation is an alternative edge reflectivity grid representation, which is invariant to laser source, angle of incidence, range, and robot surveying motion. Such a property eliminates the need of the postfactory reflectivity calibration whose time requirements are infeasible in mass-produced robots/vehicles. Our experiments demonstrate that we can achieve better performance than state of the art on ground reflectivity inference-map-based localization at no additional computational burden.
High-level web service for 3D building information visualization and analysis (2007)

This paper presents an approach to visualize and analyze 3D building information models within virtual 3D city models. Building information models (BIMs) formalize and represent detailed information related to the lifecycle of buildings, e.g., information about composition, facilities, equipment, usage, maintenance, and workflows such as rescue scenarios. Complementary, virtual 3D city models represent objects and phenomena of urban areas, typically at a lower level of information detail; virtual 3D city models as a general framework and platform for spatial data allow us to seamlessly combine GIS and BIM data. In our approach, BIM data and 3D geodata, both provided by possibly distributed, heterogeneous web services, are efficiently integrated by the underlying real-time 3D geovisualization system. To facilitate insights into complex spatial scenarios, two configurable BIM-specific visualization techniques have been developed, which map BIM data onto 3D building graphics variables respectively geometrically distort 3D building representations. The visualization functionality can itself be accessed as a specialized web 3D perspective view service. We demonstrate our approach by a fire and rescue scenario for a part of a 3D campus model.
Welche Standards braucht die Lymphknoten-Histologie beim kolorektalen Karzinom? (2006)

Das therapeutische Management des kolorektalen Karzinoms hängt entscheidend vom histologisch evaluierten Lymphknotenstatus ab. Erkenntnisse neuerer Studien weisen darauf hin, dass anstelle einer geforderten Minimalanzahl von zwölf Lymphknoten, die Präparation und histologische Untersuchung aller Lymphknoten eines Operationspräparates anzustreben ist. Dabei ist auch zu beachten, dass, trotz sachgemäßer Aufarbeitung durch den Pathologen, auch Fälle (insbesondere beim Rektumkarzinom) mit deutlich weniger als zwölf Lymphknoten vorkommen können.
A layered distributed program debugger (2002)

Debugging distributed programs is much more difficult than debugging sequential programs. One of the reasons is the communication among programs (processes) which may happen concurrently and nondeterministically. To be able to analyze such communication events is therefore an essential task for any distributed program debugger. The paper describes the design and preliminary implementation of a layered distributed program debugger. The debugger helps a user to locate bugs, to analyze a distributed program and to fix bugs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-power all-fiber wavelength-tunable thulium doped fiber laser at 2 μm (2014)

Power scaling of an all-fiber wavelength-tunable thulium doped fiber laser (TDFL) based on a monolithic master oscillator power amplifier (MOPA) system is presented. The whole configuration is comprised of a low-power seed oscillator and two stages of double-cladding thulium doped fiber amplifiers (TDFAs). The tuning of the operating wavelength is realized by inserting a spectral tunable filter into the seed oscillator. Maximum average output power of 115 W is obtained at 1950 nm with a linearly fitted slope efficiency of 51.7%. This laser has superior spectral characteristics with wavelength tunable from 1940 nm to 2070 nm. To the best of our knowledge, this is the first demonstration of an all-fiber wavelength-tunable TDFL at 2 μm with output power exceeding 100 W. The results are of great interest for many application areas.
Cultured mammalian cells attach to the invasin protein of Yersinia pseudotuberculosis. (1988)

The expression of invasin, the product of the Yersinia pseudotuberculosis inv gene, allows enteric bacteria to enter cultured mammalian cells. The ability of invasin to bind animal cells and the potential significance of this interaction in the entry process were investigated. It was found that HEp-2 cells could attach to surfaces coated with bacterial membranes containing invasin. By fractionating bacterial membrane proteins on NaDodSO4/polyacrylamide gels and transferring the protein to filters, we demonstrated that the cell-binding component of the membranes comigrated with invasin. Mutations that changed the electrophoretic mobility of the protein also caused a corresponding shift in the migration of the cell-binding activity, showing that the comigrating protein was indeed invasin. Monoclonal antibodies directed against invasin that blocked invasin-HEp-2 cell interaction also inhibited bacteria from penetrating HEp-2 cells, indicating that interaction of this protein with animal cells is critical for cellular penetration.
A Modular Approach for the Synthesis of Dibenzoazepine Derivatives (2006)

A straightforward reaction sequence consisting of a Sonogashira­ coupling of protected propargylic amines, a cobalt-catalysed­ neutral Diels-Alder reaction, DDQ oxidation of the dihydroaromatic intermediate, a sodium borohydride reduction and an acid induced Friedel-Crafts-type cyclisation approach incorporating four simple starting materials leads to polyfunctionalised polycyclic products. Based on the electronic, steric and structural preconditions either seven-membered dibenzoazepine derivatives or alternatively six- or eight-membered isoindoline derivatives are formed.
NURSING AND HEALTH CARE IN SWEDEN (2002)

Sweden, one of the Nordic countries, has a long history of social justice and equality of access to health care. Nursing plays an important role in this and nursing education is of a high standard. The aim of this paper is to describe Sweden's health system and nursing within it, thereby giving Australian nurses information which may generate an interest in, and provide background for, collaborative work. It is part of a series initiated by the first author who visited Sweden, Iceland and England in 2000 under the auspices of a Churchill Fellowship, and who has returned to Sweden and England to continue work begun during the Fellowship. Sweden's health service is characterised by an ethic of egalitarianism and high standards; primary health care plays a large role and tertiary health care is easily accessible. Nursing in Sweden is of a high standard, with devolvement of responsibility and decision-making to those working in the wards and units. Nursing education has been influenced by the historical development of nursing in Europe and today, Swedish nurses enjoy a high standard of university education with government support readily available to make specialist education accessible. Because of the similarities in both the cultures, and nursing, in Australia and Sweden, Australian nurses would find Sweden a wonderful country in which to implement cross-cultural, collaborative work.

Electro-optical test collimators for real world systems (2002)

The requirements for current and future EO system test equipment demands down-sized, multi-functional, multi-spectral, lightweight, low-cost Test Collimators. Last year's Autotestcon '94 paper titled "Down-Size Multi-Functionar EO Test Collimators" presented the Hughes Test Collimator approach of an all-metal, reflective mirror assembly, combined with an integrated target assembly, utilizing the emissivity target and other Hughes patented technologies. This year's paper will present additional technologies and capabilities, quantify measured performance results, elaborate on many of the advantages of the Hughes approach, and emphasize the multi-system, multi-functional capability.
In vitro tissue characterization and modelling using electrical impedance measurements in the 100 Hz-10 MHz frequency range (1995)

In vitro electrical impedance spectrometry was performed on tissue samples excised from sheep. Measured data have been processed to reduce dispersion in measurements and to provide criteria useful for tissue comparison. Two electrical models are proposed for tissues exhibiting a one-circle impedance locus and a two-circle impedance locus. Measurement results and electrical parameters of tissues and models fitted to experimental data are presented. Model sensitivity to parameter variations is discussed.
Carborane functionalized pyrroles and porphyrins via the Suzuki cross-coupling reaction (2006)

A new route to carboranylated pyrroles and porphyrins is reported which involves the Suzuki coupling of readily available bromo- and boronic acid-pyrroles and bromoporphyrins with functionalized carboranes; the X-ray structures of two targeted products are presented and discussed.
Intersection-priority based optimal RSU allocation for VANET (2013)

Roadside Unit (RSU) is an essential unit in a vehicular ad-hoc network (VANET) for collecting and analyzing traffic data given from smart vehicles. Furthermore, RSUs can take part in controlling traffic flow for vehicle's secure driving by broadcasting locally analyzed data, forwarding some important messages, a nd c ommunicating with o ther R SUs, a nd s o on. In order to maximize the availability of RSUs in the VANET, RSUs need to be fully distributed over an entire area. Thus, RSUs can make the best use of all traffic data gathered from every intersection. In this paper, we provide intersection-priority based RSU placement methods to find the optimal number and positions of RSUs for the full distribution providing with a maximal connectivity between RSUs while minimizing RSU setup costs. We propose three optimal algorithms: greedy, dynamic and hybrid algorithms. Finally, we provide simulated analyses of our algorithms using real urban roadmaps of JungGu/Jongrogu, YongsanGu, and GangnamGu in Seoul, each of which has a characteristic road style different than each other. We analyze how our algorithms work in such different types of roadways with real traffic data, and find the optimal number and positions of RSUs in these areas.
Behavioural rehabilitation of chronic low back pain: Comparison of an operant treatment, an operant‐cognitive treatment and an operant‐respondent treatment (1995)

Seventy-one chronic low back pain patients were assigned to one of three behavioural rehabilitation treatments or a waiting-list condition. The first intervention consisted of an operant treatment, aimed at increasing health behaviours and activity levels and at reducing pain and illness behaviours. In the second intervention, a cognitive treatment, aimed at the reinterpretation of catastrophizing pain cognitions and at enhancing self-control, was combined with an operant treatment. The third intervention consisted of the combination of the operant approach and a respondent treatment. During the respondent treatment, patients were taught to decrease muscle tension levels, using the 'applied relaxation' technique supported by EMG-biofeedback and graded exposure to tension-eliciting situations. A repeated measurements design included observer rating of pain behaviours, observer ratings of mood, self-reported depression, residual health behaviours, pain cognitions and experienced pain intensity. Follow-up assessment occurred at six months and one year after termination of treatment. Results suggest that, for the sample as a whole, improvements are found on measures of pain behaviours, health behaviours, pain cognitions and affective distress and that these improvements are maintained at six months and one year follow-up. During the treatment the three treatment groups improved significantly more than the waiting-list control group on most of the measures. Further, the results of this study provide evidence that the operant-cognitive and operant-respondent conditions are more efficacious in decreasing pain behaviours and in increasing health behaviours and efficacy expectations than operant treatment alone. This differential effect among the conditions is maintained at follow-up. Patients who received the OC and OR treatments catastrophize less than OP patients, and OC patients showed better scores on outcome-efficacy than OR patients. In general, the results suggest that behavioural rehabilitation programmes for chronic low back pain are effective and that the effects of an operant treatment are magnified when self-control techniques are added.
Extracellular vesicles from human cardiac progenitor cells inhibit cardiomyocyte apoptosis and improve cardiac function after myocardial infarction (2014)

EVs are the active component of the paracrine secretion by human CPCs. As a cell-free approach, EVs could circumvent many of the limitations of cell transplantation.
Activities of Naphthylisoquinoline Alkaloids and Synthetic Analogs against<i>Leishmania major</i> (2006)

The current treatments for leishmaniasis are unsatisfactory due to their toxic side effects, high costs, and increasing problems with drug resistance. Thus, there is an urgent need for alternative drugs against leishmaniasis. Different approaches have been used to identify novel pharmacophores against Leishmania sp. parasites, and one strategy has been the analysis of naturally occurring plant-derived compounds, including naphthylisoquinoline alkaloids. In the present study, we examined the abilities of these alkaloids to inhibit the growth of Leishmania major promastigotes and evaluated their effects on macrophages, dendritic cells, and fibroblasts. Furthermore, we determined the efficacy of selected compounds in decreasing the infection rate of macrophages and regulating their production of cytokines and nitric oxide. Our results demonstrate that the naphthylisoquinoline alkaloids ancistrocladiniums A and B (compounds 10 and 11) and the synthetic isoquinolinium salt (compound 14) were effective against intracellular amastigotes in the low submicromolar range, while toxicity against mammalian cells was observed at concentrations that were significantly higher than those needed to impair parasite replication. The activities of compounds 11 and 14 were mainly directed against the amastigote stage of L. major. This effect was not associated with the stimulation of host macrophages to produce nitric oxide or secrete cytokines relevant for the leishmanicidal function. In conclusion, our data suggest that ancistrocladiniums A and B (compounds 10 and 11) and the synthetically prepared isoquinolinium salt (compound 14) are promising candidates to be considered as lead compounds for leishmanicidal drugs.
Simultaneous Exfoliation and Functionalization of 2H-MoS<sub>2</sub> by Thiolated Surfactants: Applications in Enhanced Antibacterial Activity (2018)

Two-dimensional transition metal dichalcogenides (TMDs), such as MoS<sub>2</sub>, generally exist in two different polymorphic structures, metallic (1T phase) and semiconducting (2H phase). In context of their wide spectrum of applications ranging from electronic to biomedicine, the aspects of ligand conjugation and solution processability are highly significant. In addition, the assessment of their antibacterial property and biocompatibility is equally important to explore their biomedical applications. Here we report a new method for the exfoliation and direct functionalization of 2H-MoS<sub>2</sub> using surfactant molecules with thiol functionality. We found that the exfoliated MoS<sub>2</sub> using thiolated ligands are functionalized with desired functionality and the processing scheme can be extended to other TMDs. Functionalized 2H-MoS<sub>2</sub> exhibits highly enhanced antibacterial efficiency compared to similarly functionalized metallic 1T-MoS<sub>2</sub> against pathogenic bacteria. The newly synthesized functionalized 2H-MoS<sub>2</sub> exhibits better hemocompatibility, which makes it suitable for in vivo applications. This convenient functionalization method opens the door for many other applications of functionalized semiconducting 2H-MoS<sub>2</sub> and other TMDs.
Frequency-shaped sliding mode control for flying height of pickup head in near-field optical disk drives (2005)

To achieve stable flying height of a pickup head in near-field optical disk drives, this study investigates a discrete sliding mode control with a frequency-shaped sliding surface. A compensator is introduced in a sliding mode using a frequency-shaped performance index with linear quadratic optimal and sliding mode control. As an actuator, a piezoelectric bender is used in this study to complement an air bearing at the head/disk interface. Experiments are carried out to demonstrate that the proposed controller performs better in flying height control than an optimal sliding mode controller. Accordingly, the controller can achieve stable flying height control in the presence of certain frequency vibration of optical disks.
Identification of coagulase-negative staphylococci with the API staph system (1982)

A kit for the identification of staphylococci based on the biochemical criteria proposed by Kloos and Schleifer (W.E. Kloos and K.H. Schleifer, J. Clin. Microbiol., 1:82-88, 1975) is now available commercially. The system was used to identify 100 strains of coagulase-negative staphylococci isolated from various body sites as the primary etiological agent of clinical infection. The increasing importance of staphylococci and their resistance to antibiotics provided the rationale for such an investigation. Over 90% of the Staphylococcus isolates were easily identified as to their species on the basis of their reaction profile to 19 biochemical tests included in the kit. The remainder, which showed minor variations, could also be assigned to the various species. Identification of the isolates was as follows: S. epidermidis, 54; S. haemolyticus, 5; S. simulans, 2; S. hominis, 1; S. capitis, 4; S. cohnii, 2; S. warneri, 2; S. xylosus, 8; and S. saprophyticus, 22. Antibiotic sensitivity patterns were determined for each of the isolates. Novobiocin resistance was detected in strains of S. saprophyticus and S. xylosus, a property hitherto recognized in Micrococcus sp. type 3 causing bacteriuria in young women. Resistance to penicillin was widespread among strains of several species, whereas resistance to tetracycline was mainly confined to strains of S. epidermidis. General resistance to sulfamethoxazole and nalidixic acid was found among all strains, with almost uniform sensitivity to the other drugs tested.
Zr-SBA-15 Lewis Acid Catalyst: Activity in Meerwein Ponndorf Verley Reduction (2015)

Zr-SBA-15 Lewis acid catalyst has demonstrated an outstanding catalytic activity in the reduction of several carbonyl compounds by means of Meerwein Ponndorf Verley (MPV) reaction, using several secondary alcohols, and showing a very high selectivity towards the desired products. Special focus was addressed in the catalytic activity of Zr-SBA-15 material in the production of furfuryl alcohol from furfural, which is an important reaction for the lignocellulosic biomass valorization. In this transformation, both the reaction temperature and the i-PrOH:Furfural molar ratio exert a positive influence on the rate of the MPV transformation, with the influence of the former being much higher. i-propyl-furfuryl ether, a by-product resulting from the etherification of the target product with the sacrificing alcohol, is also found together with the main product. The production of this side-product is highly influenced by the reaction temperature, so that low temperatures and high sacrificing alcohol to substrate molar ratios have to be applied to keep its production at low levels.
The tungsten filament gun in the scanning electron microscope (1975)

The characteristics of electron guns with tungsten filaments are investigated in some detail, with particular reference to their use in electron probe instruments, and an improved method of measuring brightness is described. Consideration is given to the conditions that must be fulfilled if optimum performance is to be obtained and it is shown that current densities as high as 10 A cm -2 can be drawn from the tip of the filament without exceeding a total gun current of 1 mA.
Structural Characterization of Modified Lignin in Transgenic Tobacco Plants in Which the Activity of 4-Coumarate:Coenzyme A Ligase Is Depressed (1997)

Transgenic tobacco (Nicotiana tabacum L.) plants in which the activity of 4-coumarate:coenzyme A ligase is very low contain a novel lignin in their xylem. Details of changes in hydroxycinnamic acids bound to cell walls and in the structure of the novel lignin were identified by base hydrolysis, alkaline nitrobenzene oxidation, pyrolysis-gas chromatography, and 13C-nuclear magnetic resonance analysis. In the brownish tissue of the transgenic plants, the levels of three hydroxycinnamic acids, p-coumaric, ferulic, and sinapic, which were bound to cell walls, were apparently increased as a result of down-regulation of the expression of the gene for 4-coumarate:coenzyme A ligase. Some of these hydroxycinnamic acids were linked to cell walls via ester and ether linkages. The accumulation of hydroxycinnamic acids also induced an increase in the level of condensed units in the novel lignin of the brownish tissue. Our data indicate that the behavior of some of the incorporated hydroxycinnamic acids resembles lignin monomers in the brownish tissue, and their accumulation results in dramatic changes in the biosynthesis of lignin in transgenic plants.
