Improved Precision and Reference Materials for Stable Carbon Isotope Measurement in Basaltic Glasses using Secondary Ion Mass Spectrometry

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points High‐precision measurement results for δ13C in basaltic glasses were achieved down to 25 μg g‐1 CO2 using a refined measurement procedure via large‐geometry SIMS. Three new hydrous basaltic glasses (ETNA24, ETNA32, ETNA36) were established as reference materials.

Wintering area and experience effects on spring migration strategies, timing and breeding success in Icelandic‐nesting Common Scoters (Melanitta nigra)

open access: yesIbis, EarlyView.
Earlier spring arrival of migratory birds to breeding sites and advanced breeding often bring enhanced reproductive success but demand good body‐condition. When populations exhibit extensive winter distributions, the differing energetic costs associated with the quality and migration distance to each wintering area can have implications for individual ...

A Systematic Review Evaluating Methods for Diagnosis, Treatment and Prevention of Dental Erosions

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Aim The aim of this systematic review was to investigate the quality of evidence for methods used to diagnose, restore and prevent dental erosions, by evaluating and summarising clinical controlled studies and in situ studies covering this field.

On the Prompt Signals of Gamma Ray Bursts

open access: yes, 2013
We introduce a new model of gamma ray burst (GRB) that explains its observed prompt signals, namely, its primary quasi-thermal spectrum and high energy tail.

Imaging‐Aided VT Ablation. Long‐Term Results From a Pilot Study

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Ventricular tachycardia (VT) ablation has become a cornerstone of patient care, especially for post‐MI VT. Several strategies have proven effective for achieving rhythm control in this population, but the workflow is highly variable and depends on the physician's experience. Aim This study describes the initial systematic experience

Toward a model for leveed lava flows [PDF]

open access: yes
Many lava flows have two distinct volumetric components during emplacement. First, there is a component actively flowing in accordance with Newtonian or other constitutive relations.

Helicity asymmetries in neutrino-nucleus interactions

open access: yes, 2005
We investigate the helicity properties of the ejectile in quasi-elastic neutrino-induced nucleon-knockout reactions and consider the 12C target as a test case. A formalism based on a relativistic mean-field model is adopted.

Importance of an Evaluation Phase When Increasing the Occlusal Vertical Dimension: A Systematic Review

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 37, Issue 3, Page 669-689, March 2025.
ABSTRACT Objective To assess whether an evaluation period is necessary for patient and clinical success when increasing the occlusal vertical dimension (OVD) for a full mouth rehabilitation. Materials and Methods A systematic search was conducted in six databases: MEDLINE, Web of Science, Scopus, CENTRAL, VHL, and EMBASE.

Relative ages of lava flows at Alba Patera, Mars [PDF]

open access: yes
Many large lava flows on the flanks of Alba Patera are astonishing in their volume and length. As a suite, these flows suggest tremendously voluminous and sustained eruptions, and provide dimensional boundary conditions typically a factor of 100 larger ...

Analysis of Vesicular Basalts and Lava Emplacement Processes for Application as a Paleobarometer/Paleoaltimeter [PDF]

open access: yes, 2002
We have developed a method for determining paleoelevations of highland areas on the basis of the vesicularity of lava flows. Vesicular lavas preserve a record of paleopressure at the time and place of emplacement because the difference in internal ...
