Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Octet-baryon masses in finite space

open access: yes, 2012
We report on a recent study of finite-volume effects on the lowest-lying octet baryon masses using the covariant baryon chiral perturbation theory up to next-to-leading order by analysing the latest $n_f = 2 + 1$ lattice QCD results from the NPLQCD ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

CD8+ T cell memory is sustained in mice by hepatic stellate cells

open access: yesHepatology, EarlyView., 2022
HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.

Bone Changes With Silicone Chin Implants: Clinical Case, Review, and Considerations for Technique Modification

open access: yesPlastic and Reconstructive Surgery, Global Open
Background:. Bone resorption has been imputed to silicone chin implants as the cause of the reported bone changes with chin augmentation. Bone remodeling is complex. Both neo-ossification and bone resorption can occur. Methods:.

Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential

open access: yes, 2014
The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)].

Serum Proteomic Signatures of Rheumatoid Arthritis Risk and Response: Analysis of a Rheumatoid Arthritis Interception Trial

open access: yesArthritis &Rheumatology, EarlyView.
Objective Our study objective was to identify serum protein signatures associated with progression to rheumatoid arthritis (RA) and response to abatacept in at‐risk individuals. Methods A total of 440 serum samples from 118 APIPPRA (Arthritis Prevention In the Preclinical Phase of RA with Abatacept) study participants were selected from baseline to RA ...

Universal quantum gates based on both geometric and dynamic phases in quantum dots

open access: yes, 2003
A large-scalable quantum computer model, whose qubits are represented by the subspace subtended by the ground state and the single exciton state on semiconductor quantum dots, is proposed.

Development of a framework for implementing digital serious games in anatomy education: A single‐centre qualitative study

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Serious games are emerging as innovative tools in medical education, yet their adoption in anatomy teaching remains limited due to educator hesitancy, institutional constraints, and design challenges. This qualitative study explores the perspectives of anatomy educators on digital serious games and proposes a framework for their implementation.
