How I Investigate Borderline Prolonged aPTT: An Integrated Laboratory Approach to Mixing Studies and Factor Analysis

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Borderline prolongation of routine clotting assays—particularly the activated partial thromboplastin time (aPTT)—is a common interpretative challenge in laboratory hematology. These reproducible but mildly prolonged results often lie just beyond the upper reference limit and can trigger unnecessary follow‐up, delays, or misinterpretation ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Dependence of Biological Activity on the Surface Water Fraction of Planets

, 2019
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water bodies.

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Assessing the spatio-temporal variability of vegetation productivity in Africa: quantifying the relative roles of climate variability and human activities

International Journal of Digital Earth, 2017
Quantitative attribution at the individual pixel level of the relative contributions of climate variability and human activities to vegetation productivity dynamics across Africa is generally lacking.

Remotely Sensed Estimation of Net Primary Productivity (NPP) and Its Spatial and Temporal Variations in the Greater Khingan Mountain Region, China

, 2017
We improved the CASA model based on differences in the types of land use, the values of the maximum light use efficiency, and the calculation methods of solar radiation. Then, the parameters of the model were examined and recombined into 16 cases.

Biomechanical Assessment of Root Torque in Clear Aligners: Impact of Trimline Design, Engagers, and Pressure Points With Palatal Compensation Movement

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Background Root torque control is essential for guiding the proper movement of anterior teeth, primarily to prevent periodontal complications. This movement, in clear aligner therapy (CAT), requires precise force application to minimize unintended displacements.

Number partitioning as random energy model

, 2004
Number partitioning is a classical problem from combinatorial optimisation. In physical terms it corresponds to a long range anti-ferromagnetic Ising spin glass. It has been rigorously proven that the low lying energies of number partitioning behave like
