Effect of lip bumpers on mandibular arch dimensions
American Journal of Orthodontics and Dentofacial Orthopedics, 2009The aim of this systematic review was to examine the effects of lip bumper therapy on mandibular arch dimensions.A literature survey of PubMed, EMBASE, Cochrane Central, and Cochrane Database of Systematic Reviews (www.cochrane.org) was conducted from December 1968 to January 2007.

Seismic Safety of Arch Dams with Aging Effects
Science China Technological Sciences, 2011Arch dams suffer time-varying external loadings and harsh environment that harm their physical properties. With the aging of such dams, damage accumulates and concrete degradation inevitably appears. In this paper, a model is proposed for simulating concrete degradation with aging because of chemo-mechanical damage.

Spatial effects in multivariate ARCH [PDF]
, 2005 This paper proposes a new approach for the specification of multivariate GARCH models for data sets with a potentially large cross-section dimension. The approach exploits the spatial dependence structure associated with asset characteristics, like industrial sectors and capitalization size.

ONE-SIDED TESTING FOR ARCH EFFECTS USING WAVELETS
Econometric Theory, 2001There has been increasing interest recently in hypothesis testing with inequality restrictions. An important example in time series econometrics is hypotheses on autoregressive conditional heteroskedasticity (ARCH). We propose a one-sided test for ARCH effects using a wavelet spectral density estimator at frequency zero of a squared regression ...

Geotechnical centrifuge modelling of blast effects in dry sand: Coriolis effect and soil arching
International Journal of Physical Modelling in Geotechnics, 2023Centrifuge model tests are performed to investigate the dynamic response of dry sand under blast loading. The characteristics and propagation mode of blast waves in dry sand are studied.

On Identifying Structural VAR Models via ARCH Effects
Journal of Time Series Econometrics, 2010Abstract: We consider the local identification of parameters in structural VAR models with ARCH type errors. By establishing a mapping between the structural and reduced-form models, we provide a set of sufficient conditions for the joint identification of all parameters.

The Effect of Gender, Age, and Lateral Dominance on Arch Height and Arch Stiffness
Foot & Ankle International, 2006Background: Arch structure is known to vary widely. However, it may be linked to intrinsic factors such as gender, age, and lateral dominance. Understanding the association between these factors and arch structure may be useful in understanding injury biases that exist between individuals with different foot types.
