We decompose the market-to-book ratio into two additive components: a conservatism correction factor and a future-to-book ratio. The conservatism correction factor exceeds the benchmark value of one whenever the accounting for past transactions has been subject to an (unconditional) conservatism bias. The observed history of a firm’s past investments allows us to calculate the magnitude of its ...

We present in analytic form the three-loop O(α 2 s) correction to the H → gg partial width of the standard-model Higgs boson with intermediate mass M H ≪ 2M t. Its knowledge is required because the O(α s) correction is so sizeable that the theoretical prediction to this order is unlikely to be reliable. For M H = 100 GeV, the resulting QCD correction factor reads

In order to describe the comovements in both conditional mean and conditional variance of high dimensional nonstationary time series by dimension reduction, we introduce the conditional heteroscedasticity with factor structure to the error correction model. The new model is called the error correction–volatility factor model. Some specification and estimation approaches are developed. In partic...

First order methods are commonly used in numerical simulations of gas-solids fluidized beds because they are both stable and affordable. Unfortunately, because of the large amounts of numerical diffusion inherent to these methods higher order methods are recommended to accurately predict bed dynamics e.g., voids or bubbles. The deferred correction method and the downwind factor method are both ...

Backscattered rf signals used to construct conventional ultrasound B-mode images contain frequency-dependent information that can be examined through the backscattered power spectrum. The backscattered power spectrum is found by taking the magnitude squared of the Fourier transform of a gated time segment corresponding to a region in the scattering volume. When a time segment is gated, the edge...

there are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

background and aims: life expectancy is one of the most important indicators of health and well-being of a society. since it is claimed that in aran-bidgol region, center of iran, life expectancy is higher than the average of the country, this study was designed. methods: during a cross-sectional study, population and mortality data of kashan university of medical sciences (kaums) in 2011 were ...

Laboratory based gait analysis techniques are expensive, time consuming and require technical expertise. Inertial measurement units can directly measure temporal parameters and in combination with gait models may provide a solution to obtain spatial gait measurements within daily clinical assessments. However it is not known if a model and standard correction factor determined by Zijlstra and H...

S U M M A R Y Coda wave interferometry (CWI) utilizes multiply scattered waves to diagnose small changes in a medium by using the scattering medium as an interferometer. Since the medium is usually stationary over the duration of a seismic experiment, different (non-overlapping) time windows in the coda allow for independent estimates of the medium perturbation. If the seismograms are contamina...
