Abstract

Laser self-mixing interferometry (SMI), as an alternative contactless displacement measurement method, has extremely high resolution (pico-meter), large dynamic range and wide bandwidth. Comparing to electrostatic capacitive sensing, its detection accuracy does not depend on the gap size, electrode area, or bias voltage, which are bottlenecks for high-performance vibrating sensors. This paper presents our initial study in measuring vibrations of 3D shell resonators by laser self-mixing interferometry for application in high-performance gyroscopes. Our measurement of vibrations of a shell resonator using a VCSEL shows a noise-equivalent displacement resolution of 329pm with 100Hz bandwidth for resonator vibration amplitudes of less than 100nm, which can be improved down to $\pmb{2.2}\mathbf{pm}/\surd\mathbf{Hz}$ using low noise voltage amplifiers. If used with a fused silica shell resonator gyroscope, a rate resolution of 0.45 mdeg/hr with 1Hz bandwidth can be expected. To expand sensor dynamic range, a real-time, high-accuracy phase unwrapping technique is proposed. The scale factor of the SMI can be optimized in real time through mid-fringe point tracking by a positioning actuator.

Abstract

A pulse shape difference between photons and neutrons was observed in the output signals of scintillation light from the un-doped CsI calorimeter of the KOTO experiment for the K L → π 0 ν ν decay. We developed a discrimination method to reject neutrons and to accept photons in the deposited energy range from 0.1 to 2 GeV. The method rejects 67% of neutron-induced single hadronic clusters and 86% of neutron-induced two-cluster events while keeping more than 90% of photon-induced single electromagnetic clusters and two-photon events.

Abstract

A search for the rare decay K_{L}→π^{0}νν[over ¯] was performed. With the data collected in 2015, corresponding to 2.2×10^{19} protons on target, a single event sensitivity of (1.30±0.01_{stat}±0.14_{syst})×10^{-9} was achieved and no candidate events were observed. We set an upper limit of 3.0×10^{-9} for the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level (C.L.), which improved the previous limit by almost an order of magnitude. An upper limit for K_{L}→π^{0}X^{0} was also set as 2.4×10^{-9} at the 90% C.L., where X^{0} is an invisible boson with a mass of 135 MeV/c^{2}.

Abstract

Environmental policy instruments could be of great help to the regional economy if they are implemented in conjunction with proper economic policy options. In other words, the environment could also be an economic opportunity in a more fundamental way, using the several main drivers that could be identified to create economic value from ports. For example, the domain of port industrial development and maritime clusters could be the area in which the environment presents new economic opportunities. The purpose of this chapter is to discuss the usefulness of implementing these policy instruments with the conceptual model that is based upon the system dynamics (SD) technique. With this model, a good business case resulting in greening ports will be examined.

Abstract

Introduction: Digital healthcare with smartphone application is a promising approach to bridge the gap between hospital and community care by facilitating preventive health behavior and chronic illness management. Such technology allows healthcare professionals to integrate online coaching and consultation as part of the treatment process.Objectives: This study seeks to understand the factors predicting users’ usage of the chat function in an app-based health coaching platform.Methods: A total of 394 employees from an oil and gas company participated in health screening as part of their human resource initiatives for employee wellness. Demographic variables, biometrics, psychometrics, and other variables were collected as part of the screening. Employees with existing chronic illness (i.e. diabetes and cardiovascular disease) or the risk of developing one, as indicated by their body mass index ([BMI] > 27), blood pressure (>140/90), HbA1c (> 5.9), cholesterol (> 5.2), and depression/ anxiety/ stress levels (moderate to severe), are enrolled into a 4-month online coaching program. Pearson correlation was performed between all the variables, together with users’ total chat count in four months. Subsequently, significant variables were entered into a multiple linear regression model using the forward method, with total message count as the dependent variable.Results: The analysis included 278 sample who have been offered the coaching program. Significant zero-order correlation was found between total chat count, waistline, family history of high cholesterol, self-identified areas of improvement, ongoing medical follow up, and cholesterol level. At the multivariate level (R2 = .119, F [1, 198] = 26.62, p < .001), only total number of self- identified areas of improvement was found to be significant (β = .34, p

Abstract

Strip clusters of muons and background hits induced by gamma rays and spurious pulses are analyzed for the Forward Region Resistive Plate Chamber of the CMS/LHC. In order to perform the analysis, a real size RE2/1 prototype RPC manufactured with the final baseline design of the Forward Region RPCs was tested at the Gamma Irradiation Facility of CERN. Strip cluster sizes for muons and strip cluster rates for gamma rays are sensitive to the threshold setting while the efficiency to muons is relatively insensitive.

Abstract

The KOTO ($K^0$ at Tokai) experiment aims to observe the CP-violating rare decay $K_L \rightarrow \pi^0 \nu \bar{\nu}$ by using a long-lived neutral-kaon beam produced by the 30 GeV proton beam at the Japan Proton Accelerator Research Complex. The $K_L$ flux is an essential parameter for the measurement of the branching fraction. Three $K_L$ neutral decay modes, $K_L \rightarrow 3\pi^0$, $K_L \rightarrow 2\pi^0$, and $K_L \rightarrow 2\gamma$ were used to measure the $K_L$ flux in the beam line in the 2013 KOTO engineering run. A Monte Carlo simulation was used to estimate the detector acceptance for these decays. Agreement was found between the simulation model and the experimental data, and the remaining systematic uncertainty was estimated at the 1.4\% level. The $K_L$ flux was measured as $(4.183 \pm 0.017_{\mathrm{stat.}} \pm 0.059_{\mathrm{sys.}}) \times 10^7$ $K_L$ per $2\times 10^{14}$ protons on a 66-mm-long Au target., Comment: 27 pages, 16 figures.

Abstract

We report results on D0 and D+ production in proton-emulsion interactions at s =38.7 GeV. A fit to the form (1−|xF|)n exp (−bp 2 T ) yields n=6.9 +1.9 −1.8 and b=0.84 +0.10 −0.08 (GeV/c)−2. The total inclusive cross section, is assuming linear A dependence, is measured to be 38±3(stat.) ±13 (sys.) μb for the D0 and 38±9±14 μb for the D+. A comparison of these results with previous measurements indicates that nuclear effects do not strongly influence charm production. The predictions of QCD are in good agreement with our data.

Abstract

We present results on charm pair correlations measured in proton-emulsion interactions at s =38.7 GeV. The predictions of leading order QCD for the distributions in invariant mass, rapidity gap, xF, and polar angle in the charm pair CMS are qualitatively consistent with our measurements. The mean pT of the pairs is equal within errors to that measured in dilepton production at the same energy and mass range.

Abstract

The fraction {ital f} of {ital D}{sup 0} semimuonic decays which occur through the {ital K}{mu}{nu} mode has been measured in a hybrid emulsion spectrometer. Analysis of 124 semimuonic {ital D}{sup 0}-decay candidates gives {ital f}=0.32{plus minus}0.05 (stat) {plus minus}0.05 (syst). From this measurement and existing data on the {ital D}{sup 0} semileptonic branching ratio and lifetime, we obtain the branching ratio {ital R}({ital D}{sup 0}{r arrow}{ital K}{sup {minus}}{mu}{sup +}{nu})=(2.4{plus minus}0.4{plus minus}0.5)% and partial decay rate {Gamma}({ital D}{sup 0}{r arrow}{ital K}{sup {minus}}{mu}{sup +}{nu})=(5.6{plus minus}0.9{plus minus}1.2){times}10{sup 10} s{sup {minus}1}.

Abstract

An angular method of identifying diffractive excitation (DE) events for interactions of a hadron beam in nuclear emulsion is applied to identifying DE events in interactions of heavy ions beams. The apparent'' mean free paths (MFP) of DE processes for {sup 16}O ({sup 28}Si) beams are 1.00{plus minus}0.12, 2.4{sub {minus}0.7}{sup +1.6}, and 2.2{plus minus}0.4 (1.5{plus minus}0.2) m, respectively, at 200, 60, and 14.6 GeV/nucleon, which corresponds to 20--10% of the MFP for total inelastic interactions. Distinctive features of diffractively excited nuclei are discussed.

Abstract

Effects of c-Myc overexpression on the DNA damage-induced G2/M checkpoint were studied in finite lifespan, normal human mammary epithelial cells (HMECs). Previously, we showed that c-Myc attenuates G1/S arrest and leads to an inappropriate entry of cells with damaged DNA into the S phase, following treatment with ionising radiation (IR). Here we show that, in striking contrast to control cells, c-Myc-overexpressing HMECs demonstrate a significant attenuation of the G2/M arrest, following IR, and enter into inappropriate mitoses. At the molecular level, ectopic overexpression of c-Myc leads to an unusually high level of expression of cyclin B1, and the elevated levels of cyclin B1 were maintained, after gamma-irradiation. Introduction of DNA damage in c-Myc-overexpressing, normal mammary epithelial cells eventually induces apoptosis, indicating a dramatic sensitisation by c-Myc of DNA damage-induced apoptosis. These two remarkable phenotypes, checkpoint attenuation and sensitisation to apoptosis, resulting from a deregulation of the protooncogene c-myc, may produce a unique pattern of alternating cycles, consisting first of amplification of DNA damage, followed by apoptosis-assisted selective pressure. The result of this alternating pattern of damage apoptosis could facilitate the selection of certain genomic alterations required for cellular survival and cellular transformation.

Abstract

In this work, a new configuration of magnetorheological brakes (MRBs) is developed in order to improve the compactness, manufacturing accuracy and cost of conventional ones. In the conventional configuration of MRBs, the coil is normally wound on a nonmagnetic bobbin which is placed on the stationary housing. This causes difficulties in manufacturing and the bottle-neck problem of the magnetic circuit of the MRBs. In the proposed configuration, the nonmagnetic bobbin is eliminated and the coil is wound directly on a magnetic bobbin which is a part of the housing. In this case, the magnetic bobbin part should be designed with a contractive cross-section in order to prevent magnetic flux going through and thus forcing the magnetic flux across the MR fluid (MRF) duct. After proposing the new configurations of MRBs, the modelling of the MRBs is performed based on the Bingham rheological model of the MRF. An optimal design of the proposed MRBs and conventional MRBs is then performed based on finite element analysis of the magnetic circuit of the MRBs. A comparative work between the optimal parameters of the proposed MRBs and the conventional MRBs is conducted and the advanced performance characteristics of the proposed MRBs are then investigated. In addition, experiments on both the conventional and the proposed MRBs are performed to validate the advanced performance characteristics of the proposed MRBs.

Abstract

Up to one-third of patients with mild to moderate Alzheimer's disease may show improvement in cognitive function with tacrine, a centrally-acting, noncompetitive inhibitor of acetylcholinesterase. Candidates for tacrine must have a diagnosis of probable Alzheimer's dementia based on NINCDS-ADRDA or DSM-IV criteria and should have no history of liver disease. For patients receiving the drug, do follow-up cognitive testing with a sensitive measure such as the Alzheimer's Disease Assessment Scale. The most common adverse effects associated with tacrine therapy are elevated liver transaminases and gastrointestinal effects. Weekly blood tests are necessary to monitor liver function. A reliable caregiver is essential to ensure compliance with frequent dosing and weekly blood testing.

Abstract

Foreign bodies in the nose are commonly encountered in ORL practice. Miniature button battery impaction in the nose has rarely been reported. Seven such cases have been encountered, each suffering complications directly attributable to the button battery. The complications included septal burns in five patients leading to septal perforation in one child, one case of severe nasal bleeding and one case of necrosis of the lateral nasal wall. The site of maximal damage corresponded with the negative pole of the battery in every case. The possible explanation for this and mechanisms of cellular injury are proposed. This paper underlines the potential hazards of button batteries as foreign bodies in the nose and emphasizes the need for rapid removal and long-term follow-up of these patients.

Abstract

The diagnosis of nasopharyngeal carcinoma rests on perceptive symptom analysis, a careful clinical examination, and the selection of appropriate clinical investigations. A high index of suspicion is required. When mirror examination fails to provide a satisfactory view of the nasopharynx, flexible or rigid nasopharyngeal endoscopy is mandatory. Serologic examination of IgA antibodies to Epstein-Barr virus early antigen and viral capsid antigen is helpful in identifying high-risk patients. Biopsy material should be sent fresh to the laboratory for analysis so that special staining can be carried out in cases of doubtful diagnosis.

Abstract

The Search for Hidden Particles (SHiP) experiment proposal at CERN demands a dedicated dipole magnet for its scattering and neutrino detector. This requires a very large volume to be uniformly magnetized at B > 1.2 T, with constraints regarding the inner instrumented volume as well as the external region, where no massive structures are allowed and only an extremely low stray field is admitted. In this paper we report the main technical challenges and the relevant design options providing a comprehensive design for the magnet of the SHiP Scattering and Neutrino Detector., Minor revision, mainly to report more information concerning the analytics

Abstract

This paper presents a fast approach to simulating muons produced in interactions of the SPS proton beams with the target of the SHiP experiment. The SHiP experiment will be able to search for new long-lived particles produced in a 400~GeV$/c$ SPS proton beam dump and which travel distances between fifty metres and tens of kilometers. The SHiP detector needs to operate under ultra-low background conditions and requires large simulated samples of muon induced background processes. Through the use of Generative Adversarial Networks it is possible to emulate the simulation of the interaction of 400~GeV$/c$ proton beams with the SHiP target, an otherwise computationally intensive process. For the simulation requirements of the SHiP experiment, generative networks are capable of approximating the full simulation of the dense fixed target, offering a speed increase by a factor of $\mathcal{O}(10^6)$. To evaluate the performance of such an approach, comparisons of the distributions of reconstructed muon momenta in SHiP's spectrometer between samples using the full simulation and samples produced through generative models are presented. The methods discussed in this paper can be generalised and applied to modelling any non-discrete multi-dimensional distribution., Comment: 20 pages, 7 figures, amended as per JINST reviewer comments

Abstract

Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe and provide a dark matter candidate. The SHiP experiment will be able to search for HNLs produced in decays of heavy mesons and travelling distances ranging between $\mathcal{O}(50\text{ m})$ and tens of kilometers before decaying. We present the sensitivity of the SHiP experiment to a number of HNL's benchmark models and provide a way to calculate the SHiP's sensitivity to HNLs for arbitrary patterns of flavour mixings. The corresponding tools and data files are also made publicly available., Comment: journal version

Abstract

We report a micro-scale fused silica (FS) birdbath (BB) shell resonator with a high mechanical quality factor (Q = 1.2 million), long decay time constant (! = 43.6 s), a resonant frequency of 8.8 kHz for wineglass modes, and excellent symmetry resulting in a frequency split of only 6.7 Hz between two wineglass modes. The resonator has a volume of 41 mm 3 (radius = 2.5 mm, anchor radius = 0.5 mm, height ~ 2.1 mm). The resonator is useful in a wide range of applications, including inertial sensors, timing devices, and chemical and biological sensors.
