Investigations of the pi N total cross sections at high energies using new FESR: log nu or (log nu)^2 [PDF]
, 2002 We propose to use rich informations on pi p total cross sections below N= 10 GeV in addition to high-energy data in order to discriminate whether these cross sections increase like log nu or (log nu)^2 at high energies, since it is difficult to ...

Distributed-based massive processing of activity logs for efficient user modeling in a Virtual Campus [PDF]
, 2013 This paper reports on a multi-fold approach for the building of user models based on the identification of navigation patterns in a virtual campus, allowing for adapting the campus’ usability to the actual learners’ needs, thus resulting in a great ...

Predicting total organic carbon from few well logs aided by well-log attributes
Petroleum, 2023 Derivative/volatility well-log attributes from very few commonly recorded well logs can assist in the prediction of total organic carbon (TOC) in shales and tight formations.

Dynamic and Multi-functional Labeling Schemes
, 2014 We investigate labeling schemes supporting adjacency, ancestry, sibling, and connectivity queries in forests. In the course of more than 20 years, the existence of $\log n + O(\log \log)$ labeling schemes supporting each of these functions was proven ...

Orthogonal Matching Pursuit: A Brownian Motion Analysis [PDF]
, 2011 A well-known analysis of Tropp and Gilbert shows that orthogonal matching pursuit (OMP) can recover a k-sparse n-dimensional real vector from 4 k log(n) noise-free linear measurements obtained through a random Gaussian measurement matrix with a ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Well Log Generation Based on Hybrid Ensemble Learning Model
Cejing jishuWell logs play a crucial role in reservoir evaluation and oil and gas resource assessment. However, the shortage issue of some well logs always exists in practical applications. The well log data are remeasured through a drilling procedure involving high

Multivariate imputation via chained equations for elastic well log imputation and prediction
Applied Computing and Geosciences, 2022 Well logging is essential in studies which require an understanding of the subsurface geology and depositional conditions. Unfortunately, the measurements are rarely complete and missing data intervals are common due to operational issues or malfunction ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Well Log Evaluation Method of Shale Gas Flow Capacity
Cejing jishuThe gas-water two-phase seepage capacity of shale gas reservoir has an important influence on its productivity, but there is no method to evaluate the shale gas flow capacity directly by geophysical means such as logging.
