End‐to‐End Portfolio Optimization with Hybrid Quantum Annealing

Advanced Quantum Technologies, EarlyView.
This works presents a hybrid quantum‐classical framework for portfolio optimization that combines quantum assisted asset selection and rebalancing with classical weight allocation. The approach processes real market data, embeds it into Quadratic Unconstrained Binary Optimization formulations, and evaluates performance within a unified workflow ...

Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

Why Do They Do What They Do? A Model That Describes and Connects the Drivers of Learning Assistant Facilitation Practices

Science Education, EarlyView.
ABSTRACT Learning assistants (LAs) help implement evidence‐based teaching in undergraduate active‐learning courses and support student learning through their facilitation. Here, we present a drivers‐of‐LA‐action model with empirical evidence that connects across the macro level of LA‐supported course design and the micro level of LA‐student ...

Students’ Experiences of Teachers’ Ways of Unpacking Visual Representations in the Context of Intermolecular Forces

Science Education, EarlyView.
ABSTRACT This is the third article in a series, emanating from a project that used social semiotics and phenomenography to explore the role visual representations play in the teaching and learning of chemistry. Building on our earlier work that identified five qualitatively different ways that teachers may use to unpack visual representations in their ...

Potassium‐Doped Borophane Nanosheets: A Multifunctional Platform for Reversible Hydrogen Storage and Metal‐Free Hydrogen Transfer

Small, EarlyView.
Borophane in dual roles: as a reductant in the conversion of levulinic acid to γ‐valerolactone and as a reversible hydrogen reservoir through partial rehydrogenation. ABSTRACT 2D borophene has long been proposed as a promising hydrogen storage material, but experimental demonstrations remain limited to boron hydride sheets derived from MgB2.

Direct Write, Read, and Erase of a Vertical Heterostructure of Graphene–Monolayer Electrolyte–h‐BN Using Electric Force Microscopy

Small, EarlyView.
This work demonstrates bistable graphene doping of about 5 × 1012 cm−2$\rm{c{m}^{-2}}$ using a molecularly thin electrolyte confined between two, 2D crystals. The electrolyte's bistability enables multiple non‐volatile states with a conductive AFM tip writing, erasing, and sensing these states.
