MultiSec: Multi-Task Deep Learning Improves Secreted Protein Discovery in Human Body Fluids

open access: yesMathematics, 2022
Prediction of secreted proteins in human body fluids is essential since secreted proteins hold promise as disease biomarkers. Various approaches have been proposed to predict whether a protein is secreted into a specific fluid by its sequence.

A Well-Overflow Prediction Algorithm Based on Semi-Supervised Learning

open access: yesEnergies, 2022
Oil drilling is the core process of oil and natural gas resources exploitation. Well overflow is one of the biggest threats to safety drilling. Prediction of the overflow in advance can effectively avoid the occurrence of this kind of accident.

Graphic Symbol Recognition using Graph Based Signature and Bayesian Network Classifier

open access: yes, 2009
We present a new approach for recognition of complex graphic symbols in technical documents. Graphic symbol recognition is a well known challenge in the field of document image analysis and is at heart of most graphic recognition systems. Our method uses

Diversity Analysis of Symbol-by-Symbol Linear Equalizers

open access: yes, 2011
In frequency-selective channels linear receivers enjoy significantly-reduced complexity compared with maximum likelihood receivers at the cost of performance degradation which can be in the form of a loss of the inherent frequency diversity order or ...

Unified bit-based probabilistic data association aided MIMO detection for high-order QAM constellations [PDF]

open access: yes, 2011
A unified Bit-based Probabilistic Data Association (B-PDA) detection approach is proposed for Multiple-Input Multiple-Output (MIMO) systems employing high-order rectangular Quadrature Amplitude Modulation (QAM).

A Multi-Level Iterative Bi-Clustering Method for Discovering miRNA Co-regulation Network of Abiotic Stress Tolerance in Soybeans

open access: yesFrontiers in Plant Science, 2022
Although growing evidence shows that microRNA (miRNA) regulates plant growth and development, miRNA regulatory networks in plants are not well understood. Current experimental studies cannot characterize miRNA regulatory networks on a large scale.

Semiclassical Analysis of the Wigner $12j$ Symbol with One Small Angular Momentum

open access: yes, 2011
We derive an asymptotic formula for the Wigner $12j$ symbol, in the limit of one small and 11 large angular momenta. There are two kinds of asymptotic formulas for the $12j$ symbol with one small angular momentum.

Symbols and the bifurcation between procedural and conceptual thinking [PDF]

open access: yes, 2001
Symbols occupy a pivotal position between processes to be carried out and concepts to be thought about. They allow us both to d o mathematical problems and to think about mathematical relationships.
