Fine‐tuning ab initio XANES spectra calculations using the Bayesian optimization algorithm

Journal of Synchrotron Radiation, EarlyView.
A Bayesian optimization technique is used to tune the FEFF and FDMNES packages and to improve matching between theoretical and experimental spectra. The tests were performed on monometallic Ni, Fe and Pd K‐edge XANES spectra using several different spectrum similarity metrics.Theoretical modeling of X‐ray absorption near‐edge structure (XANES) spectra ...

Segmenting Bank Customers via RFM Model and Unsupervised Machine Learning

CoRR, 2020
In recent years, one of the major challenges for financial institutions is the retention of their customers using new methodologies of reliable and profitable segmentation. In the field of banking, the approach of offering all of the services to all the existing customers at the same time does not always work. However, being aware of what to sell, when

A Comparative Note on the Reliability of Inequality Indicator Estimates

International Statistical Review, EarlyView.
Summary The importance of accurate measurement of economic or social inequality is generally accepted. Estimators of its most popular measure, the Gini coefficient, are commonly criticised for becoming increasingly imprecise for increasingly skewed distributions and small to moderate samples, i.e., two phenomena that we face more frequently today.

Beyond Deterministic Fetal Programming: Intrauterine Exposures and the Multifactorial Origins of Adiposity

Obesity Reviews, EarlyView.
ABSTRACT Excess adiposity is not a recently developed problem but has existed since at least the upper Paleolithic, allowing evolutionary selection pressures to adapt the physiology of the pregnant woman and the feto‐placental unit for maternal and fetal protection.

A Study on the Direct Optimization of a Rational Function Model for High-Resolution Satellite Images

Remote Sensing
Due to the influence of factors such as satellite jitters, orbital errors, star sensor errors, and satellite clock errors, significant geometric systematic errors often exist among multi-view satellite images.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Association between relative fat mass and female infertility among reproductive-aged women from NHANES 2013–2020

Scientific Reports
Female infertility is a prevalent condition closely linked with obesity. Current evaluation metrics like body mass index (BMI) and waist circumference (WC) have limitations.

Optokinetic stimulation modulates vestibular contribution to postural control

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy young adults completed repeated standing balance trials while receiving stochastic vestibular stimulation (SVS) with or without optokinetic visual motion. Vestibular contributions to postural control were quantified from the frequency‐domain coupling between SVS and mediolateral ground reaction forces using coherence and ...
