A Consistent Heteroskedasticity‐Robust LM‐Type Specification Test for Semiparametric Models

Journal of Applied Econometrics, EarlyView.
ABSTRACT This article develops a heteroskedasticity‐robust Lagrange Multiplier‐type specification test for semiparametric regression models. The test is able to detect a wide class of deviations from the null hypothesis. The test statistic is based on the estimates from the restricted semiparametric model, can be computed in a regression‐based way, and

The existence and asymptotic properties of a backfitting projection algorithm under weak conditions. [PDF]

We derive the asymptotic distribution of a new backfitting procedure for estimating the closest additive approximation to a nonparametric regression function.

Count Data Models With Heterogeneous Peer Effects Under Rational Expectations

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper develops a peer effect model for count responses under rational expectations. The model accounts for heterogeneity in peer effects across groups based on observed characteristics. Identification is based on the linear model condition that requires the presence of friends of friends who are not direct friends.

Fully Modified Narrow-Band Least Squares Estimation of Stationary Fractional Cointegration [PDF]

We consider estimation of the cointegrating relation in the stationary fractional cointegration model which has found important application recently, especially in financial economics.

Profiling Protein Citrullination in Extracellular Vesicles by Single‐Molecule Detection Using Direct Stochastic Optical Reconstruction Microscopy

Journal of Biophotonics, EarlyView.
This study identifies post‐translationally citrullinated/deiminated protein cargoes co‐localised to EV subtypes, using super resolution microscopy and dSTORM imaging. The findings expand current understanding of post‐translational modifications in EV‐mediated cellular communication.

The twin peaks of learning neural networks

Machine Learning: Science and Technology
Recent works demonstrated the existence of a double-descent phenomenon for the generalization error of neural networks, where highly overparameterized models escape overfitting and achieve good test performance, at odds with the standard bias-variance ...

Cyclothymic‐hypersensitive temperament in early adolescence: Longitudinal measurement invariance and associations with psychopathology over time

JCPP Advances, EarlyView.
Abstract Background Cyclothymic‐Hypersensitive Temperament (CHT) is characterised by mood instability, interpersonal hypersensitivity, and emotional hyperreactivity, traits frequently observed in general population as well as clinical settings but often eluding strict diagnostic classifications.

Predicting peri‐implantitis incidence and implant failure via risk‐assessment and prognostication tools: A validation study

Journal of Periodontology, EarlyView.
Abstract Background Identifying individuals at high risk for developing peri‐implantitis (PI) and then determining the prognosis for implants with PI is crucial for treatment planning. Methods This study longitudinally followed implants from implant placement retrospectively.

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

Laser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.
