Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Estimating satellite and receiver differential code bias using a relative Global Positioning System network [PDF]
Annales Geophysicae, 2019 Precise total electron content (TEC) is required to produce accurate spatial and temporal resolution of global ionosphere maps (GIMs). Receivers and satellite differential code biases (DCBs) are one of the main error sources in estimating precise TEC ...

Local linear regression with adaptive orthogonal fitting for the wind power application [PDF]
, 2008 Short-term forecasting of wind generation requires a model of the function for the conversion of me-teorological variables (mainly wind speed) to power production. Such a power curve is nonlinear and bounded, in addition to being nonstationary.

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 ...

Effects of errors-in-variables on the internal and external reliability measures
Geodesy and GeodynamicsThe reliability theory has been an important element of the classical geodetic adjustment theory and methods in the linear Gauss-Markov model. Although errors-in-variables (EIV) models have been intensively investigated, little has been done about ...

Performance Capabilities of Long-Range UWB-IR TDOA Localization Systems
EURASIP Journal on Advances in Signal Processing, 2008 The theoretical and practical performance limits of a 2D ultrawideband impulse-radio localization system operating in the far field are studied under the assumption that estimates of location are based on time-difference-of-arrival (TDOA) measurements ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The application of two stage robust weighted least squares and robust bootstrapping procedure on food expenditure data. [PDF]
, 2011 This paper analysed a real data set that were obtained from a simple random sampling of Faculty of Sciences staffs in Universiti Putra Malaysia. It represents the relationship between total food expenditure (response variable) and monthly income ...
