The quiescent center (QC) plays an essential role during root development by creating a microenvironment that preserves the stem cell fate of its surrounding cells. Despite being surrounded by highly mitotic active cells, QC cells self-renew at a low proliferation rate. Here, we identified the ERF115 transcription factor as a rate-limiting factor of QC cell division, acting as a transcriptional...

Loads and working conditions of the trapezoidal cross-section of 36 m span crane beam can be analyzed by finite element method. Firstly, analysis of the stress and deformation is completed under the dangerous condition of crane beam based on the ANSYS software; secondly, find out the stress concentration and fatigue crack sensitive area of the bearing; finally, capture the position of fatigue c...

OBJECTIVE Our goal was to evaluate the influence of quality control (QC) decisions using two genotype calling algorithms, CRLMM and Birdseed, designed for the Affymetrix SNP Array 6.0. METHODS Various QC options were tried using the two algorithms and comparisons were made on subject and call rate and on association results using two data sets. RESULTS For Birdseed, we recommend using the c...

PURPOSE The purpose of our investigation was to evaluate the response and minimal residual disease by quantitative competitive PCR (QC-PCR) studies in patients with chronic myeloid leukemia (CML) treated with imatinib mesylate. EXPERIMENTAL DESIGN One hundred eighty patients with Philadelphia chromosome (Ph)-positive chronic-phase CML after IFN-alpha failure, treated with imatinib mesylate, h...

Construction equipment production rates are considered an influential factor in construction projects’ success as 30–40% of cost overruns attributed to insufficient rates. The tower crane is one the heavy equipment, and its rate has a huge impact on project’s performance. Current estimations sites not backed by universally accepted applicable methodology. However, vision-based technologies have...

—This paper presents the construction of the efficient low rate Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes and their reconfigurable structures for space information networks. The code is firstly produced by a seed AccumulateRepeat-Accumulate (ARA) protograph and then extended to a QC generalized LDPC code, where a parity check node pair is replaced with a more powerful pre-coding ...

As the flagship of Hutchison Port Holdings (HPH), Hongkong International Terminals (HIT) is the busiest container terminal on the planet. HIT receives over 10,000 trucks and 15 vessels a day, about six million twenty-foot equivalent units (TEUs) a year. HIT makes hundreds of operational decisions a minute. HIT’s terminal management system, the productivity plus program (3P), optimizes resources...

One of the primary modes for worldwide trade of goods is maritime transport, which is exposed to rapid growth. In order to handle the increase of the traffic in ports, optimization of port operations has been studied and implemented in the past. In container terminals, significant amount of work has been done in the field of large scale optimization. In published literature, the main focus lies...
