Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

Sustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.

On Pseudospherical Smarandache Curves in Minkowski 3-Space

Journal of Applied Mathematics, 2014
In this paper we define nonnull and null pseudospherical Smarandache curves according to the Sabban frame of a spacelike curve lying on pseudosphere in Minkowski 3-space. We obtain the geodesic curvature and the expressions for the Sabban frame’s vectors

Trustworthy Imagination in Embodied World Models: Structural Constraints, Reality Anchoring, and Trust Adjudication

SmartBot, EarlyView.
World models let robots imagine alternative futures, such as successfully grasping a glass or dropping it, but visual plausibility alone does not establish trustworthiness. Here, the authors review structural constraint, reality anchoring, and trust adjudication as complementary mechanisms for shaping generation, grounding predictions in real evidence,

Approximating the smallest $k$-enclosing geodesic disc in a simple polygon

Journal of Computational Geometry
We consider the problem of finding a geodesic disc of smallest radius containing at least $k$ points from a set of $n$ points in a simple polygon that has $m$ vertices, $r$ of which are reflex vertices. We refer to such a disc as a SKEG disc. We present

Strategy as a theory of change

Strategic Management Journal, EarlyView.
Abstract Research Summary The theory‐based view argues that a strategist's task is to develop a theory to move the organization to an improved future state. Focusing on theorizing as a thought process of model creation, we propose a framework to specify hypothetical causal links and analyze their structure as a directed graph connecting inputs ...

3D Reconstruction of Nanoparticle Distribution in Tumor Spheroids With Volume Electron Microscopy

Small, EarlyView.
Understanding where nanomaterials accumulate within cells is essential for revealing their biological fate and activity. We present a quantitative imaging framework to map nanomaterials and cellular structures in three dimensions. Applied to nanoparticle‐containing tumor spheroids, the approach reveals substantial cell‐to‐cell differences in uptake ...

Timelike surfaces with Bertrand geodesic curves in Minkowski 3–space

AIP Advances
Geodesic curves on a surface play an essential role in reasonable implementation. A curve on a surface is a geodesic curve if its principal normal vector is aligned with the surface normal. Using the Serret–Frenet frame, the timelike (TL) surfaces can be

Take Me Home, Country Roads: Choosing Autonomous EVs Over Personal Aviation

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the potential long‐run effects of autonomous and electric vehicles, and a carbon tax, on personal domestic aviation demand in Australia. We estimate a discrete choice disutility model with two travel modes—car and air—using Australian National Visitor Survey data and Bayesian priors. We use multiplicative Fréchet errors,
