Using pp collision data corresponding to an integrated luminosity of 5.4 fb−1 collected with the LHCb detector at a center-of-mass energy of 13 TeV, the B0 → D−D+K+π− decay is studied. A new excited Ds+ meson is observed decaying into the D+K+π− final state with large statistical significance. The pole mass and width, and the spin parity of the new state are measured with an amplitude analysis to be mR = 2591 ± 6 ± 7 MeV, ΓR = 89 ± 16 ± 12 MeV and JP = 0−, where the first uncertainty is statistical and the second systematic. Fit fractions for all components in the amplitude analysis are also reported. The new resonance, denoted as Ds0(2590)+, is a strong candidate to be the Ds(21S0)+ state, the radial excitation of the pseudoscalar ground-state Ds+ meson. © 2020, CC BY.

Information retrieval is a critical issue for everyone online. Searching for information happens all the time. To better retrieve our needs from the web, it's logical to leverage data generated by users via Web 2.0 (web of interaction). Users' actions-such as tagging a page, liking, sharing or other kinds of interaction-are used in this paper to better enhance information retrieval. The work presented in this paper used a dataset from Open Directory Project (ODP) to test the promising use of social services for better ranking of web results. We propose a framework to process social info and use it in the indexing and ranking processes. The proposed framework retrieves data from different kinds of social info (social bookmarking, social news, social network, discovery engines). Raw data is parsed into fields and significant values are either inserted into the index or used in the ranking process. Mean Average Precision (MAP) is used to evaluate results. Results are promising for using social tagging services such as Delicious. An initial assessment of the usage of other social services-for instance Facebook and so on-reveals that their data are not good enough to improve ranking of webpages. © 2015 IEEE.

Space-charge effect of the time-varying electron injection in a diode: classical and relativistic regimes

Conventionally, space-charge (SC) limited current density is defined as the maximal current density allowed to traverse a diode under a DC voltage when a time-invariant flow is injected from the cathode. In this work, we study the SC limited current density under a time-varying injection for both classical and relativistic regimes and determine the maximal amount of limited current density under certain conditions. Our simulations show that it is unlikely that a time-varying injection emitted from cathode exceeds the known SC limits, in either classical or relativistic regime. Copyright © 2017, The Authors.

850-nm vertical-cavity laser diodes with copper-plated heat sinks were fabricated and tested. Vertical-cavity surface-emitting lasers with 10μm aperture diameter and 4μm of electroplated copper demonstrated a maximum -3dB modulation bandwidth of more than 16GHz and a resonance frequency of more than 11GHz at bias current of only 5.4mA, which correspond to a bias current density of only 7.5kA/cm 2 . Thus, reported devices exhibited a high -3dB modulation bandwidth squared over bias current density ratio of more than 35GHz 2 /kA/cm 2 . The displayed 7.5 kA/cm 2 bias current density is less than the 10 kA/cm 2 current density standard for reliability by 25%. Devices also demonstrate a reduced thermal resistance of 1.01 °C/mW, a threshold current of 1.1mA, a series resistance of only 60Ω, and a maximum output power density of about 1.2mW/cm 2 .

Based on random neural networks, a cross-layer prediction model is proposed for estimating the perceptual quality of mobile video in no reference mode. The model exploits key parameters affecting video quality. Simulation results show considerable predictability performance with R-squared correlation of 0.90 and 0.39 root mean squared error.

In this paper, the recognition of and the differentiation between fall activities and activities of daily living (ADL) was performed using the MobiFall dataset. A large database was constructed to train and validate the model. Feature selection methods were implemented to reduce dimensionality. Five different classification algorithms were implemented and evaluated based on their accuracy' sensitivity, and specificity achieved. The k-Nearest Neighbors' algorithm obtained an overall accuracy of 87.5% with a sensitivity of 90.70%, and a specificity of 83.78%.

This paper presents the analysis of 28GHz solar patch antenna using the variations of transparent conductive oxides (TCO) thin film as the radiating patch. Solar antenna is basically combining the function of antenna and solar cell into one device and helps to maximize the usage of surface area. The main problem of the existing solar antenna is the radiating patch which made of nontransparent material, such as copper, shadowing the solar cell and degrades the total solar efficiency. Hence, by using the transparent conductive oxides (TCO) thin film as the radiating patch, this problem can be tackled. The TCO thin film used is varied to ITO, FTO, AgHT-4, and AgHT-8 along with glass as substrate. The simulation of the antenna executed by using computer Simulation technology (CST) Microwave Studio software demonstrated at 28 GHz operating frequency for 5G band applications. The performance of the transparent antennas is compared with each other and also with the nontransparent patch antenna that using Rogers RT5880 as substrate, operating at the same resonance frequency and then, the material that gives the best performance is identified.

The development of computer networks makes image files transportation via network become more and more convenient. However, the security of most existing image encryption methods requires to be further improved. In this paper, we present an Image Encryption algorithm combining an Improved generalized discrete Arnold transformation and a Nonlinear Chaotic map (IEIANC). It adopts the scrambling and diffusion encryption framework. First, it designs an extra 256-bit key to make the key space large enough. Next, it utilizes an improved generalized discrete Arnold transformation to scramble image pixels, and divides the scrambled image into several blocks. Finally, it applies a nonlinear chaotic map to diffuse these blocks. The experimental results show the effectiveness of the proposed algorithm. © 2016 ICIC International.

KAGRA is a 3-km interferometric gravitational wave telescope located in the Kamioka mine in Japan. It is the first km-class gravitational wave telescope constructed underground to reduce seismic noise, and the first km-class telescope to use cryogenic cooling of test masses to reduce thermal noise. The construction of the infrastructure to house the interferometer in the tunnel, and the initial phase operation of the interferometer with a simple 3-km Michelson configuration have been completed. The first cryogenic operation is expected in 2018, and the observing runs with a full interferometer are expected in 2020s. The basic interferometer configuration and the current status of KAGRA are described.
