Prevalence and Management of Behavioural and Psychiatric Symptoms on a Continuing Care Unit for Patients with Dementia

Objectives: With the increasing concerns over the safety of some pharmacological interventions or lack of sufficient evidence of effectiveness in managing neuropsychiatric symptoms in dementia, there is a constant need to review how such patients are managed. This study looks at the prevalence and management of behavioural and psychiatric symptoms amongst patients with dementia in a National Health Service (NHS) continuing care unit. Method: In this study, a survey of all 50 patients admitted to a longstay NHS-funded dementia care unit was carried out. The socio-demographic details along with severity of dementia, neuropsychiatric symptoms, and medication were obtained on all the patients. Findings: All 50 patients were prescribed some form of medication for either physical and/or mental health reasons. Only five (10%) patients were not prescribed any form of psychotropic medication. A lack of non-pharmacological treatment options for the treatment of neuropsychiatric symptoms was evident in the unit with only one occupational therapist available. Conclusion: Effective management of severe behavioural and psychiatric symptoms in dementia is challenging even in a NHS continuing care dementia unit due to the absence of clear benefit from pharmacological interventions and lack of resources for optimum non-pharmacological interventions.
Augmenting Depth Camera Output Using Photometric Stereo

We present a system for augmenting depth camera output using multispectral photometric stereo. The technique is demonstrated using a Kinect sensor and is able to produce geometry independently for each frame. Improved reconstruction is demonstrated using the Kinect’s inbuilt RGB camera and further improvements are achieved by introducing an additional high resolution camera. As well as qualitative improvements in reconstruction a quantitative reduction in temporal noise is shown. As part of the system an approach is presented for relaxing the assumption of multispectral photometric stereo that scenes are of constant chromaticity to the assumption that scenes contain multiple piecewise constant chromaticities.
Long-term antenna selection for large-scale MIMO links

In this paper antenna selection algorithms for large scale MIMO links are developed under the assumption of incomplete channel state information (CSI) at both receiver and transmitter. More specific, we assume that only long-term CSI is available for the antenna selection, but perfect CSI can be obtained for the significantly smaller effective channel that results from the antenna selection. Aim of the development is the maximization of the capacity of the resulting channels namely for the cases of high and low SNR. Additionally, the proposed selection algorithms avoid exhaustive search over all possible antenna sets, as this approach is infeasible for large antenna arrays. Finally, all results are illustrated by numeric simulations. When selecting 8 × 8 antennas out of 128 × 128 with the proposed algorithms, for Ricean K factor K = 1, a medium signal-to-noise-ratio of 10dB and strong spatial correlation the maximum spectral efficiency can be increased by more than 50 percent compared to a conventional 8 × 8 MIMO system with the same parameters.
Field Note: Phytoremediation of Petroleum Sludge Contaminated Field Using Sedge Species, Cyperus Rotundus (Linn.) and Cyperus Brevifolius (Rottb.) Hassk

The aim of this study was to degrade total petroleum hydrocarbon (TPH) in a petroleum sludge contaminated site (initial TPH concentration of 65,000–75,000 mg.kg–1) with two native sedge species namely Cyperus rotundus (Linn.) and Cyperus brevifolius (Rottb.) Hassk. Fertilized and unfertilized treatments were maintained separately to record the influence of fertilizer in TPH degradation. The average biomass production (twenty plants from each treatment) of C. rotundus was 345.5 g and that of C. brevifolius was 250.6 g in fertilized soil during 360 days. Decrease in soil TPH concentration was higher in fertilized soil (75% for C. rotundus and 64% for C. brevifolius) than in unfertilized soil (36% for C. rotundus and 32% for C. brevifolius). In unvegetated treatments, decrease in soil TPH concentration in fertilized (12%) and unfertilized soil (8%) can be attributed to natural attenuation and microbial degradation. TPH accumulation in roots and shoots was significantly higher in fertilized soil in comparison to unfertilized soils (p < 0.05). Most probable number (MPN) in planted treatments was significantly higher than in unplanted treatments (p < 0.05).
Effects of polymer structure on dissolution characteristics in chemically amplified 193-nm resists

This paper describes the effects of the blocking level of polymer on both dissolution characteristics and lithographic performance in chemically amplified positive 193 nm resists consisting of a alicyclic methacrylate polymer and a photoacid generator. There were clear relationships between the blocking level and both the dissolution rate characteristics and the lithographic performance. We found that the dissolution contracts and developer selectivity improved as the blocking level of polymer increased, and then the resolution capability was improved. However, the dry-etch resistance and adhesion property of the resist film deteriorated as the blocking level increased, although these were at the same levels as those of conventional i-line novolak resist or polyhydroxystyrene base KrF resists. Therefore, these resist materials show potential for the next generation of LSI devices. Ideal dissolution parameters for improving the resolution capability were obtained by using a resist profile simulator. By using a high-contrast resist incorporating these parameters, and by using a higher numerical aperture lens and annular illumination, the mass production of next-generation devices with a 0.12 micrometers design rule can be achieved.
Portinari: A Data Exploration Tool to Personalize Cervical Cancer Screening

Socio-technical systems play an important role inpublic health screening programs to prevent cancer. Cervicalcancer incidence has significantly decreased in countries thatdeveloped systems for organized screening engaging medicalpractitioners, laboratories and patients. The system automaticallyidentifies individuals at risk of developing the disease and invitesthem for a screening exam or a follow-up exam conducted bymedical professionals. A triage algorithm in the system aims toreduce unnecessary screening exams for individuals at low-riskwhile detecting and treating individuals at high-risk. Despite thegeneral success of screening, the triage algorithm is a one-sizefitsall approach that is not personalized to a patient. This caneasily be observed in historical data from screening exams. Oftenpatients rely on personal factors to determine that they are eitherat high risk or not at risk at all and take action at their owndiscretion. Can exploring patient trajectories help hypothesizepersonal factors leading to their decisions? We present Portinari, a data exploration tool to query and visualize future trajectoriesof patients who have undergone a specific sequence of screeningexams. The web-based tool contains (a) a visual query interface(b) a backend graph database of events in patients' lives (c)trajectory visualization using sankey diagrams. We use Portinarito explore diverse trajectories of patients following the Norwegiantriage algorithm. The trajectories demonstrated variable degreesof adherence to the triage algorithm and allowed epidemiologiststo hypothesize about the possible causes.
Introducing pilot cyclostationnarity for LTE base station number of antennas estimation

This paper deals with a new challenge for cognitive opportunistic receivers : base station number of antennas estimation. This knowledge allows to get a better understanding of the Signal to Noise Ratio and of the achievable bit-rate with the BS. This task is achieved by taking benefits of the orthogonality between the pilots patterns used by the base station antennas and making use of a the Pilot Induced Cyclo-stationarity detector proposed in [1]. To the best of our knowledge our proposed algorithm is the first technique that can estimate any number of antennas using only one antenna at reception and without any knowledge of the pilot sequence.
Secure, Efficient Data Transport and Replica Management for High-Performance Data-Intensive Computing

An emerging class of data-intensive applications involve the geographically dispersed extraction of complex scientific information from very large collections of measured or computed data. Such applications arise, for example, in experimental physics, where the data in question is generated by accelerators, and in simulation science, where the data is generated by supercomputers. So-called Data Grids provide essential infrastructure for such applications, much as the Internet provides essential services for applications such as e-mail and the Web. We describe here two services that we believe are fundamental to any Data Grid: reliable, high-speed transport and replica management. Our high-speed transport service, GridFTP, extends the popular FTP protocol with new features required for Data Grid applications, such as striping and partial file access. Our replica management service integrates a replica catalog with GridFTP transfers to provide for the creation, registration, location, and management of dataset replicas. We present the design of both services and also preliminary performance results. Our implementations exploit security and other services provided by the Globus Toolkit.
To enhance the purity and crystallinity of magnetite nanoparticles prepared by surfactant-free electrochemical method by imposing higher voltage

Magnetite (Fe3O4) nanoparticles has many important applications due to its reactivity, size, and magnetism. Many synthesis methods of the material, including electrochemical, have been developed in order to generate the desired particles. Electrochemical is one simple synthesis method in producing the nanoparticles. Characters of the particles synthesized, such as its size, crystallinity and magnetic property, depend on the electrochemical parameters like the kind and concentration of electrolyte, the kind of electrodes, the inter-electrodes distance, temperature, cell volume, current density or voltage applied. We have been succesfully synthesized monodispersed magnetite nanoparticles by electro-oxidation of iron in plain water without using any surfactant, although there are some impurities in the form of FeOOH, an intermediate species created during the formation of Fe3O4. Nevertheless a high purity of magnetite nanoparticles were required in some special applications. By applying higher voltage in the range of 30–70 V with inter-electrodes distances between 2–4 cm, it was shown by XRD and FTIR analysis that a high purity and crystalinity material have been succesfully prepared. Higher voltage enhance the rate of magnetite formation indirectly, so the reaction will be complete without retaining FeOOH anymore. It was also found from XRD, BET and VSM analysis that the imposed voltage influenced unsignificantly to the properties of the particles, but the inter-electrodes distance influenced the crystalinity, size and saturation magnetization of the particles. This way appears to be an efficient route to produce surfactant free magnetite nanoparticles.Magnetite (Fe3O4) nanoparticles has many important applications due to its reactivity, size, and magnetism.

Microgenomic Analysis in Skeletal Muscle: Expression Signatures of Individual Fast and Slow Myofibers

Background Skeletal muscle is a complex, versatile tissue composed of a variety of functionally diverse fiber types. Although the biochemical, structural and functional properties of myofibers have been the subject of intense investigation for the last decades, understanding molecular processes regulating fiber type diversity is still complicated by the heterogeneity of cell types present in the whole muscle organ. Methodology/Principal Findings We have produced a first catalogue of genes expressed in mouse slow-oxidative (type 1) and fast-glycolytic (type 2B) fibers through transcriptome analysis at the single fiber level (microgenomics). Individual fibers were obtained from murine soleus and EDL muscles and initially classified by myosin heavy chain isoform content. Gene expression profiling on high density DNA oligonucleotide microarrays showed that both qualitative and quantitative improvements were achieved, compared to results with standard muscle homogenate. First, myofiber profiles were virtually free from non-muscle transcriptional activity. Second, thousands of muscle-specific genes were identified, leading to a better definition of gene signatures in the two fiber types as well as the detection of metabolic and signaling pathways that are differentially activated in specific fiber types. Several regulatory proteins showed preferential expression in slow myofibers. Discriminant analysis revealed novel genes that could be useful for fiber type functional classification. Conclusions/Significance As gene expression analyses at the single fiber level significantly increased the resolution power, this innovative approach would allow a better understanding of the adaptive transcriptomic transitions occurring in myofibers under physiological and pathological conditions.
Molecular regulation of nephron endowment.

Recent data suggests that the number of nephrons in normal adult human kidneys ranges from ∼300,000 to more than 1 million. There is increasing evidence that reduced nephron number, either inherited or acquired, is associated with the development of essential hypertension, chronic renal failure, renal disease in transitional indigenous populations, and possibly the long-term success of renal allografts. Three processes ultimately govern the number of nephrons formed during the development of the permanent kidney (metanephros): branching of the ureteric duct in the metanephric mesenchyme; condensation of mesenchymal cells at the tips of the ureteric branches; and conversion of the mesenchymal condensates into epithelium. This epithelium then grows and differentiates to form nephrons. In recent years, we have learned a great deal about the molecular regulation of these three central processes and hence the molecular regulation of nephron endowment. Data has come from studies on cell lines, isolated ureteric duct epithelial cells, isolated metanephric mesenchyme, and whole metanephric organ culture, as well as from studies of heterozygous and homozygous null mutant mice. With accurate and precise methods now available for estimating the total number of nephrons in kidneys, more advances in our understanding of the molecular regulation of nephron endowment can be expected in the near future.
Characteristic study of fly-ash+quartz+illmenite composite coatings on copper substrates

Fly ash produced from iron and steel industries contains rich amount of metal oxides, which has the potential of using it as a coating material on structural and engineering components. This demand leads to the development and characterizes various types of composite coatings of fly ash by using a robust technique, that is, plasma spraying. Plasma spray technology has the advantage of being able to process various low-grade minerals to obtain value-added products and also to deposit metals, ceramics and a combination of these, generating approximately homogeneous coatings with the desired microstructure. In the present investigation, coatings are developed on copper substrates using fly-ash+quartz+illmenite composite at various plasma torch input power levels ranging from 11 to 21 kW DC. Metallographic and chemical characterization of the produced composite coatings was performed with the aid of scanning electron microscopy and X-ray diffraction analysis. The adhesion strength was measured by using coatin.
Characterization and Corrosion Behaviour Study on Biocompatible Ti-6Al-4V Component Fabricated by Electron Beam Melting

Ti-6Al-4V biocompatible material to be used as an implant, fabricated by Electron Beam Melting, was investigated for mechanical properties viz. hardness, grain size and porosity. Phase characterization was analysed by X-ray diffraction; morphological and micro structural features were assessed by Scanning Electron Microscopy and Optical Microscope respectively. The as-produced Electron beam melted Ti-6Al-4V sample had increased surface roughness and a thick surface oxide layer. The corrosion behaviour in simulated body fluid environment was compared for wrought and Electron beam melted Ti-6Al-4V samples by performing anodic polarization measurement using sequencer computer controlled potentiostat. The Electron beam melted sample had the corrosion rate of 0.0148 mils per year and wrought sample had 0.0196 mils per year.
Graph-based modelling on the robustness of interconnected networks under attack

In this report a number of graph theoretical concepts are introduced and their relevance to network modelling is discussed, in particular the ability to capture the robustness of an internetwork. A novel graph model is described that successully generates networks with realistic properties, in order to simulate various internetwork scenarios. The main objective was to devise a more robust method of interconnecting networks by considering different internetwork topologies and interconnection methods. A quantitative investigation was carried out using MATLAB to simulate abstract networks being attacked, and the analysis led to some qualitative conclusions. It was found that a strategy for choosing interconnecting nodes based on a preferential attachment basis may significantly increase internetwork robustness, and that internetwork topologies with a central intermediary network significantly increase the connectivity across the internetwork. These findings have significant implications for future graph-based network research, as more robust methods of creating internetworks can be devised from them.
Investigations on the full polarimetric PALSAR data to discriminate macrophytes species in the Amazon floodplain wetland

The purpose of this work is to evaluate the capacity of full polarimetric L band data to discriminate macrophyte species in Amazon wetland. Fieldwork was carried out almost simultaneously to the acquisition of the full polarimetric PALSAR data. Coherent and incoherent attributes were extracted from the image, and macrophyte morphological variables were measured on the ground. The image attributes and the macrophyte variables were compared in order to evaluate their application for discriminating macrophytes species. The findings suggest that polarimetric information could be adopted to discriminate plant species based on morphology, and that estimation of plant biomass and productivity could be improved by using the polarimetric information.

Human-face-tracking using visual servoing by patient robot

Human-body models imitating a part of human body have been used for medical training. But those models seem not to suit training because they cannot be felt to be similar to actual humans. Therefore, the simulator being felt like a real human is required for the medical trainees being able to assess patient's physical and emotional conditions, since medical care procedures are vital to watch out patient's pains given by the care treatment itself to avoid failures leading the patients to dangerous conditions. Based on the needs for medical training by using human-like robot, we have developed a simulator for injection training called “patient robot. ” Patient robot has to behave like humans to make the medical training effective, so we introduced a visual servoing system into the patient robot so that the patient robot can gaze at a trainee's face like humans or turn away its face form the medical procedures. We executed some experiments of gazing at a rotating object using visual servoing, in which actual object's positions, patient robot's gazing point and pose-tracking data have been measured. We confirmed patient robot can track real human faces.
DEPENDENCE OF MAGNIFICATION UPON THE CAMERA‐TO‐EYE DISTANCE IN THE ZEISS FUNDUS CAMERA

The magnification of the Zeiss type of fundus camera depends, except for the case of emmetropy, on the camera‐to‐eye distance. Its relative variation is equal to the product of the patient's ametropia and the difference in the camera‐to‐eye distance. Moreover, magnification is also affected by changing the diopter range scales on the camera.
The scintillating grid illusion is enhanced by binocular viewing

The scintillating grid illusion is an intriguing stimulus consisting of a grey grid on a black background, with white discs at the grid intersections. Most viewers perceive illusory “scintillating” black discs within the physical white discs, especially at non-fixated locations. Here, we report for the first time that this scintillation percept is stronger when the stimulus is viewed binocularly than when it is presented to only one eye. Further experiments indicate that this is not simply because two monocular percepts combine linearly, but involves a specifically cyclopean contribution (Schrauf & Spillmann, 2000). However, the scintillation percept does not depend on the absolute disparity of the stimulus relative to the screen. In an intriguing twist, although the basic illusion shows more scintillation when viewed binocularly, when the illusion is weakened by shifting the discs away from the grid intersections, scintillation becomes stronger with monocular viewing.
