Predicting the height of fractured water-conducting zone (FWCZ) can be challenging due to their significant grey characteristics and difficulty in scientifically selecting relevant influencing factors. To address this issue, we utilized Pearson correlation analysis method entropy identify factors degree with FWCZ. Based on this, several constructed models were optimized, reliability best regres...

The effects of different levels of dietary cellulose on colonic crypt mitotic activity and colon carcinogenesis were studied in 190 male Sprague-Dawley rats. Rats were divided into groups and fed a basal fiber-free diet supplemented with either 0, 5, or 15% pure cellulose (w/w), for periods of 10 weeks (initiation stage) or 32 weeks (promotional stage). Half of the rats in each group were given...

STATEMENT OF PROBLEM In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood. PURPOSE The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions...

We investigate the scaling properties of postmortem fracture surfaces in silica glass and glassy ceramics. In both cases, the 2D height-height correlation function is found to obey Family-Viseck scaling properties, but with two sets of critical exponents, in particular, a roughness exponent zeta approximately 0.75 in homogeneous glass and zeta approximately 0.4 in glassy ceramics. The ranges of...

introduction: electrophysiological studies have demonstrated a relationship between aging and atrioventricular (av) nodal conduction and refractoriness. the aim of the present study was to determine the effects of nodal aging on dynamic av nodal field potential recording during atrial fibrillation (af) in rabbit. methods: two groups of male new zealand rabbits (neonatal 2-week-olds and adult 12...

In this research, a cold model of internally circulating fluidized bed is investigated. The aim is to find the effects of some of the operating parameters on the performance of the reactor. Experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). The bed was loaded with white silica particles (dp = 0.15 -...

The accurate calculation of the height fractured water-conducting zone (FWCZ) is great significance for mine optimization design, water disaster prevention, and safety production coal mines. In this article, a height-prediction model FWCZ based on extreme learning machine (ELM) proposed. To address issues low prediction accuracy challenging parameter optimization, we optimized ELM using gray-wo...
