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

The 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).

The Vector Vortex Coronagraph: Laboratory Results and First Light at Palomar Observatory [PDF]

, 2009
High-contrast coronagraphy will be needed to image and characterize faint extra-solar planetary systems. Coronagraphy is a rapidly evolving field, and many enhanced alternatives to the classical Lyot coronagraph have been proposed in the past ten years ...

Prior osteosynthesis—unlike osteotomy—raises revision risk after total knee arthroplasty, predominantly via periprosthetic infection

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee surgery is discussed as a risk factor for total knee arthroplasty (TKA), yet most reports do not distinguish between osteotomy and osteosynthesis. The German Operationen‐ und Prozedurenschlüssel (OPS)‐based classification was used to compare the impact of these procedures on implant survival, mortality and complications ...

Comparison of die geometry for cold drawing of multi-rifled steel tubes

Metalurgija, 2019
Multi-rifled tubes, i.e. tubes with multiple inner grooving are used in heat exchangers and boilers, providing favourable heat transfer conditions due to turbulent flow of cooling medium. Therefore, strict requirements are placed on the geometry of inner

Statistical mechanics of the vertex-cover problem

, 2003
We review recent progress in the study of the vertex-cover problem (VC). VC belongs to the class of NP-complete graph theoretical problems, which plays a central role in theoretical computer science.

The number of guards needed by a museum: A phase transition in vertex covering of random graphs

, 2000
In this letter we study the NP-complete vertex cover problem on finite connectivity random graphs. When the allowed size of the cover set is decreased, a discontinuous transition in solvability and typical-case complexity occurs.

Probiotic supplementation during pregnancy for vaginal microbiota improvement and pathogen clearance: A systematic review and meta‐analysis

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Probiotic supplementation during pregnancy shows a modest, non‐robust increase in Group B Streptococcus decolonization, with no consistent benefit for bacterial vaginosis or vulvovaginal candidiasis. Probiotics may serve as a non‐antibiotic adjunct, but standardized regimens and ecological diagnostic frameworks are required.
