Quantitative Susceptibility Mapping in Skull Base Chordoma: In Silico Analysis and In Vivo Application Towards Indirect Hypoxia Assessment

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate quantitative susceptibility mapping (QSM) beyond the brain through realistic simulations and to explore preliminary evidence that may be indicative of hypoxia in skull base chordomas (SBC). Methods Each step of the QSM pipeline was optimized within an in silico framework consisting of (i) phase unwrapping, (ii) background ...

Theoretical Properties Of Multinomial Logistic Regression [PDF]

open access: yes, 1983
A large sample relative efficiency of estimation for multinomial logistic regression compared to multiple group discriminant analysis has been derived and evaluated for parameter values relevant to epidemiological research. The large sample distributions of the two procedures are based on the assumptions of multivariate normality and common covariance ...

Conditional Generative Modeling for Enhanced Credit Risk Management in Supply Chain Finance

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT The rapid expansion of cross‐border e‐commerce (CBEC) has created significant opportunities for small‐ and medium‐sized sellers, yet financing remains a critical challenge due to their limited credit histories. Third‐party logistics (3PL)‐led supply chain finance (SCF) has emerged as a promising solution, leveraging in‐transit inventory as ...

Bayesian estimation for multinomial logistic regression

open access: yes, 2020
Bu tez, Somali'de belirli bir yaştaki gençlerin mutluluğunun, yaş ve eğitim düzeyi gibi iki açıklayıcı değişken ile incelenmesinde, Bayesçi multinomiyal lojistik regresyon modelinin uygulanabilirliğini savunmaktadır. Multinominal lojistik regresyon yöntemi, parametrelerin posterior (sonsal) yoğunluğunun kestirilmesinde, klasik yöntem ve Bayesçi ...

Reconsidering climatic predictors for high‐resolution niche models of alpine plants

open access: yesOikos, EarlyView.
The increasingly acknowledged and consequently also better understood microclimatic variability in terrestrial ecosystems has motivated a call for finer spatial resolution in species distribution modelling, especially in the case of sedentary low‐stature organisms such as plants.

Anisotropic community turn‐over at habitat edges informs on assembly drivers: simulation and empirical test on soil macrofauna

open access: yesOikos, EarlyView.
Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...
