What do established companies do to factor in sustainability into their business models?
Abstract This study examines the motivations for businesses to integrate sustainability into their business models (BMs) and how they can innovate those models to become more sustainable. The concept of business model innovation for sustainability (BMIfS) has emerged as a viable means to help companies innovate sustainable business models (SBMs ...

Simple high-order Galerkin finite element scheme for the investigation of both guided and leaky modes in axially anisotropic planar waveguides [PDF]
A simple high-order Galerkin finite element scheme is formulated to compute both the guided and leaky modes of anisotropic planar waveguides with diagonal permitivity tensor.

First submillimeter observation of CO in the stratosphere of Uranus [PDF]
Context. Carbon monoxide (CO) has been detected in all Giant Planets and its origin is both internal and external in Jupiter and Neptune. Despite its first detection in Uranus a decade ago, the magnitude of its internal and external sources remains unconstrained. Aims. We targeted CO lines in Uranus in the submillimeter range to constrain its origin.

Abstract The dynamics of giant planet magnetospheres is controlled by a complex interplay between their fast rotation, their interaction with the solar wind, and their diverse internal plasma and momentum sources. In the ionosphere, the Hall and Pedersen conductances are two key parameters that regulate the intensity of currents coupling the ...

New Moons of Uranus and Neptune from Ultradeep Pencil-beam Surveys
We have conducted extremely ultradeep pencil-beam observations for new satellites around both Uranus and Neptune. Tens of images on several different nights in 2021, 2022, and 2023 were obtained, shifted, and added together to reach as faint as 26.9 and ...

High spectral resolution observations of Uranus' near-IR thermospheric $H_2$ emission spectrum using the IGRINS spectrograph during the 2018 and 2023 apparition [PDF]
Ground-based near-IR observations have revealed that Uranus anomalously hot upper atmosphere, detected by Voyager 2, has been steadily cooling. The observed $H_3^+$ and $H_2$ emission-line spectra probe Uranus' ionosphere and thermosphere, respectively.
