Zhu; J. Sun; H. Xin; C. Zheng; Tzong-Ru TsaiJournal of Testing and Evaluation 49We propose an empirical Bayesian (EB) procedure with a rebate warranty policy to search for optimal sampling plans for three-parameter Burr-type XII distribution (3pBXIID) under truncated life testing. The proposed method requires fewer assumptions than its competitors to search for optimal sampling plans when the lifetimes of products follow a 3pBXIID. The Newton–Raphson method using the quasi-Newton (QN) algorithm, the evolution algorithm method using the particle swarm optimization (PSO) algorithm and genetic algorithm (GA) are used in the proposed EB procedure to search for reliable estimates of the parameters in the Bayesian model, and the obtained estimates are denoted as QN-EB, PSO-EB, and GA-EB, respectively.

Hiraoka,; M. Suzuki; K. D. Tsuei; H. Ishii; Y. Q. Cai; M. W. Haverkort; C. C. Lee; W. KuEurophysics Letters(EPL) 96(3), 37007We have studied the dd excitations in NiO over three-dimensional momentum (q) space using nonresonant inelastic X-ray scattering. In addition to the previously reported peaks at 1.7 and 3.0 eV, another peak is found at 1.0 eV, with a dramatically different intensity distribution in momentum space.Contrary to the other two peaks that form oval structures maximizing at [111] directions, the 1.0 eV peak displays appreciable intensity along low-symmetry axes near [311] and [210], but vanishes in the three principal axes [100], [110], and [111], indicating a significant difference in the exciton wave function.We find good agreement between the experimental data and two

Lett. 116, 066601The recent discovery of the first Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature. Such a topological semimetal features a novel type of anomalous surface state, the Fermi arc, which connects a pair of Weyl nodes through the boundary of the crystal. Here, we present theoretical calculations of the quasiparticle interference (QPI) patterns that arise from the surface states including the topological Fermi arcs in the Weyl semimetals TaAs and NbP. Most importantly, we discover that the QPI exhibits termination points tha

Am. Chem. Soc., 138(46) 15197Aggregates of proteins containing polyglutamine (polyQ) repeats are strongly associated with several neurodegenerative diseases. The length of the repeats correlates with the severity of the disease. Previous studies have shown that pure polyQ peptides aggregate by nucleated growth polymerization and that the size of the critical nucleus (n*) decreases from tetrameric to dimeric and monomeric as length increases from Q18 to Q26. Why the critical nucleus size changes with repeat-length has been unclear. Using the associative memory, water-mediated, structure and energy model, we construct the aggregation free energy landscapes for polyQ peptides of different repeat-lengths. These studies show that the monomer of the shorter repeat-length (Q20) prefers an extended conf

However, no analytical closed formula solutions of the maximum likelihood estimates (MLEs) of BXIID parameters can be obtained based on progressively type I interval-censored (PTIIC) samples. In this manuscript, the differential evolution algorithm (DE) and quasi-Newton method (QN) are applied to searching the MLEs of BXIID parameters based on PTIIC samples. The performance of DE and QN is evaluated by means of Monte Carlo sim

The purpose is to keep legitimate two-way relay users exchange their information via a helping multiantenna relay with QoS guarantee while avoiding the exchanged information overhearing by unauthorized receiver. To this end, we propose a physical layer method, where the relay beamforming is jointly designed with artificial noise (AN) which is used to interfere in the unauthorized user's reception. We formulate the joint beamforming and AN (BFA) design into an optimization problem such that the received signal-to-interference-ratio (SINR) at the two legitimate users is over a predefined QoS thre

A scheduling scheme that satisfies QoS requirements has become more important for wireless communications. We propose a downlink scheduling scheme called adaptive priority-based downlink scheduling (APDS) for providing QoS guarantees in IEEE 802.16 networks. APDS comprises two major components: Priority assignment and resource allocation. Different service-type connections primarily depend on their QoS requirements to adjust priority assignments and dispatch bandwidth resources dynamically. We consider both starvation avoidance and resource management. Sim

It considers handover parameters for, including interference, velocity, RSS and quality of service (QoS) level.

Both MIR and FIR photoresistance are observed in a single chip by utilizing cyclotron resonance in the quantum Hall regimes of graphene and two-dimensional electron gas (2DEG) in GaAs=ðAl; GaÞAs heterostructure, respectively. By cooperatively operating 2DEG as a back-gate electrode to change the carrier density of graphene or graphene as a top-gate electrode to modulate the carrier density of 2DEG with an applied gate voltage less than 1 V and applying the magnetic field to tune cyclotron resonance, we achieve a wide frequency selectivity, covering 640–7

The energy spacing between ground and excited state is observed to be decreased with decrease in dGaAs and increased with increase in excitation intensity. The rate of carrier capture and energy relaxation in QDs is found to be slower at excitation energy of 3.06 eV than that at 1.53 eV which is attributed to intervalley scattering in GaAs.

Ce sujet a déjà été étudié ou abordé par plusieurs experts. Dans notre article, nous adoptons une approche concrète, en commençant par évoquer le cas d’un artiste qui est l’un des personnages du roman : l’écrivain Bergotte. Pour Marcel (qui est le nom que porte le narrateur dans le roman), Bergotte est la personne l’ayant initié pendant sa jeunesse à la pratique de l’écriture et à la beauté artistique. Nous expliquerons la raison de cette fascination. Plus tard, quand Bergotte s’affaiblissait par l’âge, le narrateur rencontra d’autres artistes (com

The authors showed that q(x) on the interval [0,1] can be uniquely determined by the interior twin-dense nodal subset W_T([0,1]), or W_T([a_0,1]), respectively. Using the above results, two uniqueness theorems of the spherically symmetric speed of sound η(r) for acoustic scattering problems are obtained.en1569-3945 (online)國外SCI;Yu Ping Wang否DEU

By tuning the magnetic field and gate voltage, we find robust conductance peaks and dips on the plateau of one conductance quantum 2 e 2 / h . These features fall into two types associated with two different collective quantum states: for the first type, only dips and the crossing behaviors are found, and their traces show an anomalous temperature dependence, named “reversed Coulomb blockade oscillation”, whereas for the second type, the peak traces show both crossing and ant

Without consideration of importance of image, camera sensors can capture images of the intruder crossing the barrier but cannot guarantee that the captured images are the important portion of the intruder. Without consideration of breadth of image, image identification may be difficult.

Baillie; Chung, HuiminGARCH;autocorrelations;Bartlett's formula;QMLE.Journal of Time Series Analysis 22(6), pp.631–650This paper shows how the parameters of a stable GARCH(1, 1) model can be estimated from the autocorrelations of the squared process. Specifically, the method applies a minimum distance estimator (MDE) to the sample autocorrelations of the squared realization. The asymptotic efficiency of the estimator is calculated from using the first g autocorrelations. The estimator can be surprisingly efficient for quite small numbers of autocorrelations and, in some cases, can be more efficient than the quasi maximum likelihood estimator (QMLE). Also, the estimated process can better fit the pattern of observed autocorrelations of squared returns than those from models estimated by maximum likelihood estimatio

Among various ETFs, we adopt NASDAQ 100 Index Tracking Stock (QQQ) as the sample because it has corresponding volatility index (VIX) issued which is necessary. The results show that all volatility models applied in this study can reliably forecast volatility. The Glosten-Jagannathan-Runkle GARCH model is superior to the GARCH model, implying that the return volatility of QQQ is asymmetric. Among the added incremental information, QQQ Volatility Index (QQV) of the Am
