FGF9–FGFR2 Signaling via Osteocytes‐Preosteoblasts Crosstalks to Mediate Mechanotransduction‐Driven Intramembranous Osteogenesis in the Underdeveloped Maxilla

open access: yesAdvanced Science, Volume 12, Issue 44, November 27, 2025.
This study identifies osteocyte‐derived FGF9 as a mechanosensitive factor that impairs osteogenesis in the underdeveloped maxilla by inducing FGFR2 nuclear translocation in preosteoblasts. Mechanical stimulation reduces FGF9 secretion, relieving its inhibitory effect. These findings reveal a novel osteocyte–preosteoblast FGF9–FGFR2 axis in craniofacial

Photon pair generation using four-wave mixing in a microstructured fibre: theory versus experiment

open access: yes, 2006
We develop a theoretical analysis of four-wave mixing used to generate photon pairs useful for quantum information processing. The analysis applies to a single mode microstructured fibre pumped by an ultra-short coherent pulse in the normal dispersion ...

Schneiderian Membrane Elevation up to 8 mm by Transcrestal Technique Using Hollowed Osteotomes: A Human Cadaver Study

open access: yesClinical Implant Dentistry and Related Research, Volume 27, Issue 5, October 2025.
ABSTRACT Purpose The objective of this study was to compare the detachment surfaces of Schneiderian membrane elevation of 4–8 mm by transcrestal technique using hollowed osteotomes on human cadavers with 4 mm residual bone height. Methods The study followed the CACTUS (ChAracteristics of Cadaver Training and sUrgical Studies) guidelines.

Cryptococcus gattii Genotype VGI Infection in New England [PDF]

open access: yesPediatric Infectious Disease Journal, 2011
Cryptococcus gattii is a known, emerging infectious disease pathogen predominantly in the Pacific Northwest, the United States, and British Columbia, Canada. We report a case of an immunocompetent adolescent from New England who had severe pulmonary and central nervous system infection caused by the VGI genotype of C. gattii.

Assessing the Validity of OpenStreetMap for Food Environment Research

open access: yesGeographical Analysis, Volume 57, Issue 4, Page 592-601, October 2025.
ABSTRACT This study assessed agreement between food environment measures derived from OpenStreetMap (OSM) data, a commercial dataset, and an administrative dataset (the Canadian Food Environment Dataset, Can‐FED) to better understand the suitability of OSM food‐related data for food environment research.

Evaluating the quality of VGI and authoritative data in red-crowned crane conservation: a comparative study

open access: yesBig Earth Data
Volunteered Geographic Information (VGI) has emerged as a valuable resource in citizen science, yet concerns about its data quality remain. While prior studies have focused on specific data types or platforms, few have systematically evaluated ...

Mapping with Stakeholders: An Overview of Public Participatory GIS and VGI in Transport Decision-Making

open access: yesISPRS Int. J. Geo Inf., 2019
Transport decision-making problems are typically spatially based and involve a set of feasible alternatives with multiple evaluation criteria. Besides, transport decisions affect citizens’ quality of life, as well as specific interests of general ...

Geographically Weighted Cronbach's Alpha (GWalpha): An Exploratory Local Measure of Reliability for Scale Construction

open access: yesGeographical Analysis, Volume 57, Issue 4, Page 758-772, October 2025.
ABSTRACT Scales, as survey instruments, are crucial for investigating people's attitudes and behaviors in social science research. Cronbach's alpha is the most frequently used measure of internal consistency reliability for multi‐item survey scales. Affected by the spatial context of respondents' locations, the reliability of responses to a scale may ...
