Energies, 2015 A two-stage algorithm is proposed for the estimation of the fundamental frequency of asynchronously sampled signals in power systems. In the first stage, time-domain interpolation reconstructs the power system signal at a new sampling time and the ...

Two Stage Estimation in Semiparametric Model
DEStech Transactions on Materials Science and Engineering, 2017 Considering the semi-parametric surveying adjustment models. Firstly, the estimators of parameters and nonparametric are derived by using the kernel function and least square method. Secondly, discuss the approach of bandwidth choice in the semi-parametric surveying adjustment models.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Two-Stage Marker Detection–Localization Network for Bridge-Erecting Machine Hoisting Alignment
SensorsTo tackle the challenges of complex construction environment interference (e.g., lighting variations, occlusion, and marker contamination) and the demand for high-precision alignment during the hoisting process of bridge-erecting machines, this paper ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Semantic Attention Guided Hierarchical Decision Network for Age Estimation
Applied SciencesImage-based human age estimation has been a hot topic in the field of face attribute recognition. As the greatest dilemma of age estimation is the similar appearance of adjacent age labels, this paper presents a two-stage age estimation model based on ...

Estimation under two stage random permutation models
Metrika, 1985 In a simple two-stage random permutation model the units which have fixed but unknown values \(x_{ij}\) of the study variate x, are labelled randomly in two stages, first the psu's are labelled at random and then the ssu's within each of the psu's are labelled at random independently.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
