Extending 3DCityDB with Oracle AI Database Support and LLM-Based Natural Language Interfaces

The open-source 3D City Database (3DCityDB) is a widely used solution for storing and managing semantic 3D city models based on the CityGML standard. Its latest version 5 introduces a redesigned and highly generic schema along with a JSON-based schema mapping mechanism, which was...

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional properties of materials. However, experimental analysis of these localized electric fields and the corresponding charge distribution remains...

An empirical analysis of electric vehicles’ charging patterns at public charging infrastructure across neighbourhood archetypes

To promote the uptake of electric vehicles, a well-developed public charging infrastructure (PCI) is essential, particularly in areas with limited access to private charging, as in many inner-city quarters in Europe, where private parking areas are rare. To better understand wher...

Quadratic word equations with regular constraints and the exponent of periodicity

Abstract In this article, we study word equations in free semigroups and the conjecture that the existence of infinitely many solutions entails the existence of solutions with arbitrarily large exponent of periodicity. We examine this question in the broader framework of word equ...

The Road to Nowhere: Being Rooted in a Region Does Little to Predict Support for Populist Parties or Opposition to Migration and Social Change

ABSTRACT In his influential book The road to somewhere David Goodhart claims that a split between a majority of people who are rooted in particular places or groups (the “Somewheres”) and a minority of people who are or can be at home anywhere in the world (the “Anywheres”) is at...

Quantum computing solution of the Bethe–Salpeter equation for relativistic scalar bound states via tensor-network VQE

Abstract We present a gate-based quantum computing solution of the homogeneous Bethe–Salpeter equation (hBSE) for the bound state of two massive relativistic scalar particles interacting via ladder-approximation scalar exchange. After Wick rotation to Euclidean space and O(4) S-w...

Crystallized: Towards Resinless Fabrication of Complex Nonlinear Spatial Forms Using Fiber-Reinforced Crystal Composites (FRCCs) and Coreless Filament Winding (CFW) Techniques

Petroleum-based resins used in fiber-reinforced composites (FRCs) offer high performance but carry a substantial environmental burden. This study investigates crystallized composites (CCs) as a resinless alternative capable of binding loose cotton reinforcement within a crystalli...

Exciting Objects for Historical Research—Mechanical Gyroscopes in Germany Between 1925 and 1975

ABSTRACT The contribution presents a dissertation project in the history of science and technology that uses gyro instruments as objects of historical research, offering exciting opportunities for investigation using a wide variety of methodological approaches. This paper present...

Repeated stretch-shortening cycles enhance force and work despite brief deactivation between cycles

Stretch-shortening cycles (SSCs) enhance force and mechanical work compared with pure shortening contractions and are fundamental to locomotion. Although SSC mechanics are well studied, it remains unclear whether mechanical cycle-to-cycle carryover effects persist across repeated...

A Partitioned Coupling Approach for Electromechanics Simulations of Skeletal Muscles Using FEBio

ABSTRACT This work presents a partitioned coupling approach for electromechanical simulations of skeletal muscles. For the first time, we couple our highly specialized electrophysiology solver, which computes both force generation in muscle cells and action potential propagation...

Adenylation Domain Engineering Enables Biosynthesis of an Improved Polymyxin Antibiotic

ABSTRACT Polymyxins are potent nonribosomal peptide antibiotics, yet their clinical use is limited by a narrow therapeutic window and nephro‐/neurotoxicity. Conventional efforts to improve these agents rely on the incorporation of nonnatural building blocks that cannot be accesse...

Low-Dimensional Ionotronics

Abstract Ionotronics encompasses a broad range of phenomena and devices based either on the electron-controlled manipulation of ions in electrolytic media or on the use of ionic behavior to control electronic functionality. Although the term itself is relatively recent, the scien...

Encouraging Growth in Programming Education: Does Growth Mindset Feedback Influence Learning?

Abstract Tutoring systems enable individualized support for diverse learners. Feedback is one of the most influential factors shaping learning, yet the optimal form of feedback remains an open question. Growth mindset feedback emphasizes effort and the value of errors. It has sho...

Defined Dinuclear Nickel Sites on Mesoporous Silica Translate Molecular Surface Mimics to Heterogeneous Catalysis

ABSTRACT Metal–metal cooperativity in dinuclear transition‐metal systems offers unique opportunities for controlling reactivity and selectivity in catalytic transformations. Here, we report, inspired by molecular chemistry, the assembly of a bimetallic nickel system grafted onto...

Design and Implementation of an AR System for Real-Time Urban Model Editing and Visualization

Abstract. Urban planning increasingly relies on 3D city models and geospatial databases for sustainable development. However, no complete system currently offers immersive 3D visualization of building attributes in augmented reality (AR), bidirectional attribute editing propagate...
