Comments on "The long-period Galactic Cepheid RS Puppis. I. A geometric distance from its light echoes"

open access: yes, 2008
The luminous Galactic Cepheid RS Puppis is unique in being surrounded by a dust nebula illuminated by the variable light of the Cepheid. In a recent paper in this journal, Kervella et al.

Non‐destructive orientation tracking of individual β‐Sn grains in die‐attach solder joints

open access: yesJournal of Synchrotron Radiation, EarlyView.
This study introduces inclined scanning three‐dimensional X‐ray diffraction microscopy (i‐S3DXRD) that enables three‐dimensional orientation mapping of planar polycrystalline materials, revealing the thermal fatigue mechanism of Pb‐free solder joints.Understanding the failure mechanisms of Pb‐free solder joints during thermal cycling is a critical ...

Calibration of GLONASS Inter-Frequency Code Bias for PPP Ambiguity Resolution with Heterogeneous Rover Receivers

open access: yesRemote Sensing, 2018
Integer ambiguity resolution (IAR) is important for rapid initialization of precise point positioning (PPP). Whereas many studies have been limited to Global Positioning System (GPS) alone, there is a strong need to add Globalnaya Navigatsionnaya ...

Multiple frequency range imaging to remove measurement ambiguity [PDF]

open access: yes, 2009
Range imaging systems use a specialised sensor to capture an image where object distance (range) is measured for every pixel using time-of-flight. The scene is illuminated with an amplitude modulated light source, and the phase of the modulation envelope

On the regularization ambiguities in loop quantum gravity

open access: yes, 2005
One of the main achievements of LQG is the consistent quantization of the Wheeler-DeWitt equation which is free of UV problems. However, ambiguities associated to the intermediate regularization procedure lead to an apparently infinite set of possible ...

Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Research on GPS geometry-based observational stochastic error model

open access: yesTongxin xuebao, 2019
Aiming at the problem of not enough influencing factors were considered in traditional methods,a much more realistic stochastic model was built.In which error corrections were introduced into the geometry-based function model,an improved least squares ...

Human + AI in Accounting: Early Evidence from the Field

open access: yesJournal of Accounting Research, EarlyView.
ABSTRACT This paper provides early evidence on the integration and impact of generative artificial intelligence (GenAI) in accounting at the accountant and task levels. Using survey data from 277 professional accountants, we document substantial heterogeneity in adoption patterns, perceived benefits, and concerns about GenAI.

Impact of medium-scale traveling ionospheric disturbances on network real-time kinematic services: CATNET study case

open access: yesJournal of Space Weather and Space Climate, 2020
Medium-scale traveling ionospheric disturbances (MSTIDs) are fluctuations in the plasma density that propagate through the upper layer of the atmosphere at velocities of approximately 100 m/s and periods reaching some tens of minutes.

Generating Abstractive Summaries from Meeting Transcripts

open access: yes, 2016
Summaries of meetings are very important as they convey the essential content of discussions in a concise form. Generally, it is time consuming to read and understand the whole documents.
