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

, 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 ...

Prevalence of C‐Shaped Canals in Maxillary Molars in an Iranian Population: A Cone‐Beam Computed Tomography Analysis

International Journal of Clinical Practice, Volume 2026, Issue 1, 2026.
Objectives Understanding the morphology of the root canal is important for successful endodontic treatment. Studies have revealed the role of geographical and racial diversity in root canal anatomical variations. Considering the lack of enough study on the prevalence of C‐shaped canals in maxillary molars in Iran, the present study aimed to investigate

quando una GSDI Conference in Italia? Insieme è possibile!

GEOmedia, 2009
When a GSDI Conference in Italy? Together it's possible The collaboration between web log authors and GEOmedia may help "neo" and "paleo" geographers (following the neologisms introduced by Ed Parsons) to have a long-lasting dialogue.

The potentials of vehicle-grid integration on peak shaving of a community considering random behavior of aggregated vehicles

Next Energy
With large-scale electric vehicles (EVs) promoted and connected to the power grid, the uncontrolled charging of EVs enlarges the peak-valley range of load in the distribution grid.

A Deep Metric Learning and Multimodal Gated Fusion Framework for AI‐Driven Risk Assessment of Lingual Plate Perforation and Mandibular Canal Injury in Posterior Mandible Implants

International Journal of Dentistry, Volume 2026, Issue 1, 2026.
Objective To provide an automated risk assessment for lingual plate perforation (LPP) and mandibular canal injury (MCI) in dental implants. Also, to reduce interoperator variability in risk classification and eliminate manual measurements during implant planning.

Monocular Navigation in Large Scale Dynamic Environments

, 2017
We present a processing technique for a robust reconstruction of motion properties for single points in large scale, dynamic environments. We assume that the acquisition camera is moving and that there are other independently moving agents in a large ...

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

Advanced 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
