many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

In this paper we consider a stochastic server modeling a multiclass communi cation switch fed by a set of parallel bu ers The dynamics of the system evolve in discrete time and the generalized processor sharing GPS scheduling policy of is implemented The arrival process in each bu er is an arbitrary and possibly autocorrelated stochastic process We obtain a large deviations asymptotic for the b...

We show that the only ow solving the stochastic di erential equation (SDE) on R dXt = 1{Xt>0}W+(dt) + 1{Xt<0}dW−(dt), where W and W− are two independent white noises, is a coalescing ow we will denote φ±. The ow φ± is a Wiener solution. Moreover, K = E[δφ±|W+] is the unique solution (it is also a Wiener solution) of the SDE K s,tf(x) = f(x) + ∫ t s Ks,u(1R+f )(x)W+(du) + 1 2 ∫ t s Ks,uf ′′(x)du...

Background Outdoor work is associated with high and chronic exposure to solar ultraviolet radiation which might lead an increased risk of developing skin (pre)malignancies. Prevalence actinic keratosis (AK), basal cell carcinoma (BCC), cutaneous squamous (cSCC) melanoma (cM) in Dutch outdoor workers (OW) has not previously been investigated. Objective This study compares the prevalence premalig...

A continuous simulation approach is proposed for estimating water temperature exceedance probabilities using thermo-hydrodynamic modeling. The approach uses (1) a deterministic unsteady ow and heat transport model, (2) continuous hydrological and meteorological data for a long historical period, and (3) synthetic records of tributary water temperatures and other model inputs. Representative his...

This study is concerned with developing a two-dimensional multiphase model that simulates the movement of NAPL in heterogeneous aquifers. Heterogeneity is dealt with in a probabilistic sense by modeling the intrinsic permeability of the porous medium as a stochastic process. The deterministic nite element method is used to spatially discretize the multiphase ow equations. The intrinsic permeabi...

Activated water irrigation has been widely investigated as an effective production increasing measure. However, the response of activated in plant growth and use efficiency (WUE) with amount is not well understood. Here, a pot experiment was conducted to determine effects on winter wheat growth, yield, WUE under amount. Twelve treatments included four types, (i) tap (TW), (ii) magnetization (MW...

The predictability of a chaotic series is limited to a few future time steps due to its sensitivity to initial conditions and the exponential divergence of the trajectories. Over the years, streamfl ow has been considered as a stochastic system. In this study, the chaotic nature of daily streamfl ow is investigated using autocorrelation function, Fourier spectrum, correlation dimension method (...

fifty-four specimens of the kingsoldier bream, argyrops spinifer (forsskal, 1775) from coastal waters of the persian gulf, in bushehr province, were aged by otolith readings to assess the suitability of using otolith length/weight for age estimation in this fish. otolith length and weight increased along with an increase in length and age of the fish. the relationship between fish length (tl) a...

background: aflatoxins (afs) are the most prevalent carcinogenic mycotoxins, produced mainly by aspergillus flavus and a. parasiticus. the general purpose of the present study was to use dehydroacetic acid (dha) and ozonated water (ow) to control a. flavus growth and accumulation of aflatoxin b1 (afb1) in iranian pistachios. methods: three treatment pistachio groups were separately immersed in ...
