[Lasers in dentistry 2. Diagnosis of dental caries with lasers]. (2002)

When enamel, dentine and substances in caries lesions are exposed to (laser) light of a specific colour, fluorescence may be induced. This principle is at the basis of two caries diagnostic methods, DIAGNOdent and Quantitative Laser (Light-induced) Fluorescence (QLF). Only the DIAGNOdent is commercially available. Bacterial porphyrins evoke fluorescence when illuminated with red light and the intensity of the emitted light is related to the size of the caries lesion. Published research indicates that the DIAGNOdent is particularly suitable for detecting small bacteria containing caries lesions, and to monitor such lesions. QLF is based on the fluorescence decrease in demineralised enamel upon exposure to blue-violet (laser) light. The intensity of the emitted light is related to the amount of mineral loss in the caries lesion. Using QLF the mineral loss in caries lesions can be measured quantitatively. Like the DIAGNOdent, QLF is particularly suitable to monitor caries lesions.
Neuronal regeneration enhances the expression of the immunophilin FKBP- 12 (1995)

Immunophilins are a group of proteins that serve as receptors for the immunosuppressant drugs cyclosporin A and FK506. The immunophilin designated FK-506 binding protein-12 (FKBP-12) is concentrated more than 10 times higher in the brain than in immune tissues. The complex of FK506 and FKBP-12 inhibits the calcium activated phosphatase, calcineurin, increasing phosphorylated levels of calcineurin substrates with growth associated protein-43 (GAP-43), being most prominent in the brain. We now demonstrate an association of FKBP-12 with neuronal regeneration and GAP-43 disposition. Facial nerve crush markedly augments expression of FKBP-12 mRNA in the facial nucleus with a time course paralleling changes in GAP-43 mRNA. Following sciatic nerve lesions, similar increases in FKBP-12 mRNA occur in lumbar motor neurons and dorsal root ganglia neuronal cells. Increased FKBP-12 expression appears linked to regeneration rather than degeneration as facial nerve lesions elicited by ricin injection, which produce neuronal death without regeneration, fail to augment FKBP-12 expression in the facial nucleus. The time course for accumulation of FKBP-12 in sciatic nerve segments following nerve crush indicates rapid axonal transport at a rate similar to GAP-43.
A study of the hazard of fire and explosion due to electric charge by Gas-Solids flow in pipeline (2000)

When fire and explosion accidents have occurred due to a leak of the flammable gas involving the LNG & LPG in an industrialized society, it is a very important problem. Accordingly, in this paper, we have compared and analyzed the occurrence transition and the electrostatic energy according to dust supplies and pressure variations for the electric charge due to the gas-solids of pipe flow. As the experimental results, if dust amounts and the initial pressure increased, electric charge in the pipe and the exit increased. The Specific charge of increased proportionally if the initial pressure increased but if the quantity of dust increased, the specific charge decreased. Energy increased significantly as the dust amounts and the initial pressure increased. The possibility of fire and explosion exist in the measuring point(M 1) and the Faraday cage if natural gas and LPG were used.
Understanding and detecting data fabrication in large-scale assessments (2018)

Purpose Fabricated data jeopardize the reliability of large-scale population surveys and reduce the comparability of such efforts by destroying the linkage between data and measurement constructs. Such data result in the loss of comparability across participating countries and, in the case of cyclical surveys, between past and present surveys. This paper aims to describe how data fabrication can be understood in the context of the complex processes involved in the collection, handling, submission and analysis of large-scale assessment data. The actors involved in those processes, and their possible motivations for data fabrication, are also elaborated. Design/methodology/approach Computer-based assessments produce new types of information that enable us to detect the possibility of data fabrication, and therefore the need for further investigation and analysis. The paper presents three examples that illustrate how data fabrication was identified and documented in the Programme for the International Assessment of Adult Competencies (PIAAC) and the Programme for International Student Assessment (PISA) and discusses the resulting remediation efforts. Findings For two countries that participated in the first round of PIAAC, the data showed a subset of interviewers who handled many more cases than others. In Case 1, the average proficiency for respondents in those interviewers’ caseloads was much higher than expected and included many duplicate response patterns. In Case 2, anomalous response patterns were identified. Case 3 presents findings based on data analyses for one PISA country, where results for human-coded responses were shown to be highly inflated compared to past results. Originality/value This paper shows how new sources of data, such as timing information collected in computer-based assessments, can be combined with other traditional sources to detect fabrication.
Arterial baroreflex alters strength and mechanisms of muscle metaboreflex during dynamic exercise (2004)

Previous studies showed that the arterial baroreflex opposes the pressor response mediated by muscle metaboreflex activation during mild dynamic exercise. However, no studies have investigated the mechanisms contributing to metaboreflex-mediated pressor responses during dynamic exercise after arterial baroreceptor denervation. Therefore, we investigated the contribution of cardiac output (CO) and peripheral vasoconstriction in mediating the pressor response to graded reductions in hindlimb perfusion in conscious, chronically instrumented dogs before and after sinoaortic denervation (SAD) during mild and moderate exercise. In control experiments, the metaboreflex pressor responses were mediated via increases in CO. After SAD, the metaboreflex pressor responses were significantly greater and significantly smaller increases in CO occurred. During control experiments, nonischemic vascular conductance (NIVC) did not change with muscle metaboreflex activation, whereas after SAD NIVC significantly decreased with metaboreflex activation; thus SAD shifted the mechanisms of the muscle metaboreflex from mainly increases in CO to combined cardiac and peripheral vasoconstrictor responses. We conclude that the major mechanism by which the arterial baroreflex buffers the muscle metaboreflex is inhibition of metaboreflex-mediated peripheral vasoconstriction.
An Inversion-Based Synthesis Approach for Area and Power Efficient Arithmetic Sum-of-Products (2008)

In state-of-the-art digital signal processing (DSP) and graphics applications, the arithmetic sum-of-product (SOP) is an important and computationally intensive operation, consuming a significant amount of area, delay and power. This paper presents a new algorithmic approach to synthesize a non-timing critical SOP block in an area-efficient and power-efficient way, which can be very useful to reduce the size and power consumption of the non timing-critical portion in the design. We have divided the problem of generating the SOP into three parts: inversion-based creation of the BitClusters (sets of individual partial-product bits, which belong to the i <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> bitslice), propagation-based reduction of the BitClusters and selective-inversion based computation of the final sum result. Techniques used in these three steps help to reduce the implementation area and power consumption for the SOP block. Our experimental data shows that the SOP block generated by our approach is significantly smaller (8.59% on average) and marginally faster (0.42% on average) than the SOP block generated by a commercially available best-in-class datapath synthesis tool. In addition, our proposed SOP netlist consumes significantly less dynamic power (7.92% on average) and leakage power (5.65% on average) than the netlist generated by the synthesis tool. These improvements were verified on placed-and-routed designs as well.
A "Model Assisted Probability of Detection" approach for ultrasonic inspection of railway axles (2012)

The reliability of non-destructive testing is usually quantified in terms of the “Probability of Detection” curves relating a characteristic linear dimension of the considered defects to the probability to observe them. Actually, POD curves are also function of other implicit factors, so they can be considered stochastic in nature and, consequently, the most rational and reliable approach to their derivation should also consider the determination of a suitable confidence level. The problem arises because such confidence level is usually requested to be equal to 95% for POD curves, so involving high costs and long times for the needed experimental tests. The present paper is focused on the reliability of ultrasonic inspection applied to hollow railway axles. In particular, a novel method, recently proposed by the authors, for the interpretation of POD data is firstly described and experimentally validated. Eventually, with the aim to lower the overall experimental costs, the possibility to substitute part of the needed experimental tests with proper numerical simulations, so applying the so-called “Model Assisted Probability of Detection” approach, is successfully investigated.
Mie Resonances Enabled Subtractive Structural Colors with Low-Index-Contrast Silicon Metasurfaces (2022)

All-dielectric structural colors are attracting increasing attention due to their great potential for various applications in display devices, imaging security certification, optical data storage, and so on. However, it remains a great challenge to achieve vivid structural colors with low-aspect-ratio silicon nanostructures directly on a silicon substrate, which is highly desirable for future integrated optoelectronic devices. The main obstacle comes from the difficulty in achieving strong Mie resonances by Si nanostructures on low-index-contrast substrates. Here, we demonstrate a generic principle to create vivid bright field structural colors by using silicon nanopillars directly on top of the silicon substrate. Complementary colors across the full visible spectrum are achieved as a result of the enhanced absorption due to Mie resonances. It is shown that the color saturation increases with the increasing of the nanopillar height. Remarkably, blue and black colors are generated by trapezoid nanopillar arrays as a result of the absorption at long wavelengths or all visible wavelengths. Our strategy provides a powerful scheme for accelerating the integrated optoelectronic applications in nanoscale color printing, imaging, and displays.
Development and analysis of novel electroluminescent yarns and fabrics for localized automotive interior illumination (2012)

Textiles used in automotive interiors can be used to provide localized illumination if made to illuminate. In this study a novel electroluminescent (EL) yarn has been developed that can be integrated with knitted and woven fabrics. An EL yarn construction and an appropriate EL coating have been studied; moreover, a novel automated single yarn coating system has also been developed. An analytical model of the luminance of this yarn was also created based on alternating current thin-film EL technology. An automated EL yarn driver system, which electrically drives the yarn to provide illumination, and an illuminance measurement system to detect its illumination have been explained. The luminescence of the EL yarn has been analyzed based on the luminance derived by the analytical model and the illuminance detected by the measurement system. Finally, knitted fabrics integrated with this yarn are described with possible applications in automotive or aerospace interiors.
Neuromuscular electrical stimulation exercise: a potential alternative to conventional exercise in the management of type 2 diabetes (2017)

Aims: Exercise is fundamental in the prevention and treatment of type 2 diabetes (T2D). However, many individuals face barriers to exercise. Neuromuscular electrical stimulation (NMES) is an alternative to conventional exercise that may prove beneficial in the treatment of T2D. The aim of this study was to investigate the effects of an 8-week NMES exercise programme in a T2D population. Methods: A repeated measures one-group cohort intervention study was conducted. Thirteen T2D participants (age 52.0±6.9 years, height 1.79±0.06 m, weight 104.5±11.9 kg, BMI 32.8±4.3 kg/m2) underwent an 8-week NMES intervention. Venous blood markers, body composition, blood pressure, quadriceps strength and predicted maximal oxygen consumption were assessed at baseline and after the 8-week intervention. Results: Significant improvements in fasting plasma glucose, percentage body fat and peak isometric quadriceps torque were noted following the intervention (p&lt;0.05). Conclusions: The principal findings of this study were that NMES can improve body composition, muscle strength and glycaemic control in T2D participants. NMES may therefore provide an alternative to those individuals with T2D who have barriers to exercise participation. Further randomised controlled trials with larger participant numbers are required to investigate this further.
Video-based Person Re-identification with Accumulative Motion Context (2017)

Video based person re-identification plays a central role in realistic security and video surveillance. In this paper we propose a novel Accumulative Motion Context (AMOC) network for addressing this important problem, which effectively exploits the long-range motion context for robustly identifying the same person under challenging conditions. Given a video sequence of the same or different persons, the proposed AMOC network jointly learns appearance representation and motion context from a collection of adjacent frames using a two-stream convolutional architecture. Then AMOC accumulates clues from motion context by recurrent aggregation, allowing effective information flow among adjacent frames and capturing dynamic gist of the persons. The architecture of AMOC is end-to-end trainable and thus motion context can be adapted to complement appearance clues under unfavorable conditions (e.g. occlusions). Extensive experiments are conduced on three public benchmark datasets, i.e., the iLIDS-VID, PRID-2011 and MARS datasets, to investigate the performance of AMOC. The experimental results demonstrate that the proposed AMOC network outperforms state-of-the-arts for video-based re-identification significantly and confirm the advantage of exploiting long-range motion context for video based person re-identification, validating our motivation evidently.
Limited feedback in multiple-antenna systems with one-bit quantization (2015)

Communication systems with low-resolution analog- to-digital-converters (ADCs) can exploit channel state information at the transmitter (CSIT) and receiver. This paper presents initial results on codebook design and performance analysis for limited feedback systems with one-bit ADCs. Different from the high-resolution case, the absolute phase at the receiver is important to align the phase of the received signals when the received signal is sliced by one-bit ADCs. A new codebook design for the beamforming case is proposed that separately quantizes the channel direction and the residual phase.

Mode coupling in a coastal wedge with a sloping thermocline (2021)

Internal waves populate multiple stratified aquatic systems and are one of the most energetic high-frequency events in shallow water and deep ocean, causing strong currents and turbulence. In this paper, propagation of a sound signal is considered in a wedge-like area in the presence of an internal Kelvin wave, which causes periodic diurnal changes of the thermocline depth along the acoustic track. This, in turn, leads to periodic inclination of the thermocline in the vertical plane, which causes sound field fluctuations at the vertical line array. Analysis of the experimental data and numerical modeling suggest that physical reasons for the sound field variability are 1) mode coupling in the area, where time-dependent normal mode eigenvalues approach each other (i.e., quasi-cross-section), 2) fluctuations of the normal modes’ attenuation coefficients. Numerical modeling is carried out within the framework of the Parabolic equation and normal modes theory.
On the design of a class of CNN's for ECG classification (2011)

The paper discusses the possibility of using the dynamics of a class of Cellular Neural Networks (CNN's) for electrocardiogram (ECG) signals classification. The main idea is that of segmentation and transformation of the temporal signal into a 1D spatial one which is further processed by means of a bank of linear spatial filters using a parallel architecture of CNN type. A major advantage of the proposed solution is the independence of the filters spatial frequency characteristics on the number of samples of the ECG pattern, which allows dealing very easily with the heart rate variability. The principle of the proposed architecture is briefly discussed and the design of a bank of spatial filters for ECG classification is presented. Transistor level simulation and considerations regarding the architecture reconfiguration are given as well.
Algal growth on organic compounds as nitrogen sources (1999)

Two experimental series were run to evaluate the potential of algal development on dissolved organic nitrogen (DON) compounds as the sole source of nitrogen (N) nutrition. Monocultures of several common Lake Kinneret algae (<it>Pediastrum duplex, Synechococcus</it> sp.,<it>Microcystis aeruginosa, Aphanizomenon ovalisporum</it> and<it>Cyclotella</it> sp.) were incubated for 3 weeks in the laboratory with different inorganic (NH4<sup>+</sup>, NO3<sup>-</sup>) or organic (hypoxanthine, urea, guanine, ornithine, glucosamine, lysine) nitrogen sources. Even though the cultures were not axenic, marked differences were observed in algal growth response.<it>Pediastrum, Cyclotella</it> and<it>Aphanizomenon</it> grew well on most N sources, and cyanobacterial growth and yield were consistently greatest when the urea was the only N source. We also followed algal growth and eventual species dominance in batch samples of GF/F-filtered lake water, supplemented with orthophosphate and different inorganic or organic N compounds and inoculated with concentrated lake phytoplankton. Although no clear impact on phytoplankton growth (as chlorophyll concentration) was observed, in seven out of 11 experiments we could discern changes in the algal species that became dominant in flasks with different organic and inorganic N sources. Our results are consistent with the proposition that components of the DON pool are not only an important potential, direct or indirect N source for phytoplankton, but also that different algal species can exploit these sources with varying capabilities so that different N substrates may selectively stimulate the development of dominant algal species.
Structural and nuclear magnetic resonance studies of short selenium–nitrogen bonds (1985)

SeCl4 reacts with Ph3PNSiMe3(2) by elimination of SiMe3Cl to form Ph3PNSeCl3(3), which is converted to (Ph3PN)2SeCl2(4) by a further mole of (2). Compound (4) may also be prepared from (2) and SeOCl2, or Se2Cl2; (4) reacts with SbCl5 to form [(Ph3PN)2SeCl]+[SbCl6]–(5). 2,4,6-Tri-t-butylaniline and SeOCl2 give chloro-N-(4,6-di-t-butyl-2-oxocyclohexa-3,5-dien-1-ylidene)selenamide, (7). Compounds (3),(4),(5), and (7), the previously reported diphenyl-N-(p-toluenesulphonyl)selenimide, (1), and 5,6-dimethyl-2,1,3-benzoselenadiazole, (8), have been studied by 77Se n.m.r.; the crystal structures of (1), (3), (4), and (7) have been determined by X-ray diffraction. The Se–N bond lengths of 1.787(6), 1.680(4), 1.735(4), and 1.766(4)Å all indicate significant Se–N multiple bonding when compared with Se–N bonds from the literature, but curiously the longest of the four is in (1), the only structure containing a formal double bond. Although bond length alternation indicates that the quinone type resonance extreme predominates for (7), the Se–N and Se–O distances are shorter than in an analogous compound, N-(3,5-dimethyl-2-oxocyclohexa-3,5-dien-1-ylidene)phenylselenamide, the Se–O distance being reduced by 0.5 Å to 2.079(3)Å.
Management of stage II seminoma. (1998)

Radiation therapy is highly effective in patients with stage IIA or IIB seminoma (89% were relapse free). In stage IIC or IID disease, although local control with RT is excellent, a 50% risk of distant relapse is unacceptable, and not all patients who relapse can be salvaged. Chemotherapy should clearly be the primary treatment in patients with stage IIC or IID seminoma.
Copy-Move Image Forgery Detection Using Local Binary Pattern and Neighborhood Clustering (2013)

This paper introduces a copy-move image forgery detection method based on local binary patterns (LBP) and neighborhood clustering. In the proposed method, an image is first decomposed into three color components. LBP histograms are then calculated from overlapping blocks from each component. The histogram distance between the blocks is calculated and the block-pairs having the minimal distance are retained. If the retained block-pairs are present in all the three color components, they are selected as primary candidates. 8-connected neighborhood clustering is then applied to refine the candidates. The proposed method shows significant improvement in reducing the false positive rates over some recent related methods.
