Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model

Business Strategy and the Environment, EarlyView.
ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

Indirect transitions of a signal interacting with a moving refractive index front

, 2014
This research was supported by the German Research Foundation DFG (EI 391/12-2).The dynamic manipulation of light can be achieved by the interaction of a signal pulse propagating through or reflected from a refractive index front.

Imaging transverse flow velocity using spectral bandwidth of the Doppler frequency shift in phase-resolved ODT [PDF]

, 2002
The Doppler bandwidth extracted from the standard deviation of the frequency shift in phase-resolved optical Doppler tomography (ODT) is used to image the velocity component transverse to the probing beam.

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Implant‐related orofacial pain managed with implant apicoectomy: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background In recent years, the use of implants has emerged as a widely accepted method for the replacement of missing teeth. Although rare, chronic pain associated with implant placement has been reported in the literature. Conversely, apicoectomy, the removal of the apical portion has been integrated into the implantology field in cases with

The Space-Based Altimeter Echo-Signal when Doppler Scattering is taken Into Account

Известия высших учебных заведений России: Радиоэлектроника, 2017
In the analytical approximation of time dependent average power of a satellite altimeter echo-signal (power profile) the Doppler scattering of individual specular point responses is usually neglected.

Channel characteristics analysis of train-to-train wireless communication

Journal of Measurement Science and Instrumentation, 2021
Train-to-train（T2 T） communication can provide protection for existing train-to-ground private network communication, and its channel characteristics directly affect the application of upper-layer communication technologies.

Doppler-Raman crossover in resonant scattering

, 2020
We consider theoretically light scattering by a resonant layer that periodically moves in real space. At small frequencies of motion the scattered light spectrum reveals the frequency shift that is governed by the Doppler effect.

Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Extended Kalman Filtering of Satellite Doppler Tracking Data and IT¡¯S Application to Orbit Determination Problems [PDF]

Journal of Astronomy and Space Sciences, 1995
Using a directional antenna, the Doppler effect of satellites can be detected and the orbital elements can be obtained by the Extended Kalman Filter with the observed frequency shift data. We obtained the orbital elements of NOAA-11 by the application of
