From “Mirror Flower, Water Moon” to Multi‐Task Visual Prospective Representation Learning for Unmanned Aerial Vehicles Indoor Mapless Navigation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Vision‐based deep learning models have been widely adopted in autonomous agents, such as unmanned aerial vehicles (UAVs), particularly in reactive control policies that serve as a key component of navigation systems. These policies enable agents to respond instantaneously to dynamic environments without relying on pre‐existing maps.

Group twin coloring of graphs

open access: yes, 2018
For a given graph $G$, the least integer $k\geq 2$ such that for every Abelian group $\mathcal{G}$ of order $k$ there exists a proper edge labeling $f:E(G)\rightarrow \mathcal{G}$ so that $\sum_{x\in N(u)}f(xu)\neq \sum_{x\in N(v)}f(xv)$ for each edge ...

From Rare to Common: The Live Streaming Industry of Jadeite Trade in Ruili in the China–Myanmar Borderlands

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT Since the early years of the 21st century, the city of Ruili has grown to be a major trade hub for Burmese jadeite on the China–Myanmar border. Starting from 2016 to 2017, Ruili's jadeite trade shifted heavily to online live streaming transactions through media platforms like Douyin, RedNote/Xiaohongshu, and Taobao/Tmall.

When should firms watch for cross‐industry competition? A demand‐side perspective

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.

In Search of Structure’ Links Across Length Scales: Crossover Among Structural Motifs, Energetics, and Magic Systems in Subnanometer Transition Metals Clusters

open access: yesSmall Structures, EarlyView.
Evolution of structural motifs of transition metal systems from tetramers and hexamers to bulk phases is studied. Clusters of transition metal (TM) elements are becoming increasingly important in our daily lives for a wide ensemble of applications in catalysis and bio‐fields, for health, energy and environmental problems.

Erving Goffman at 100: A Chameleon Seen as a Rorschach Test within a Kaleidoscope

open access: yesSymbolic Interaction, EarlyView.
The 100th anniversary of Erving Goffman's birth was in 2022. Drawing on his work, the Goffman archives, the secondary literature, and personal experiences with him and those in his university of Chicago cohort, I reflect on some implications of his work and life, and the inseparable issues of understanding society.

A Systems Engineering Methodology for System of Autonomous Systems: Test and Evaluation

open access: yesSystems Engineering, EarlyView.
ABSTRACT Recent advances in artificial intelligence and machine learning (AI/ML) have resulted in autonomous systems that reduce operators' workload and involvement in hazardous missions. Integrating these systems into an existing system of systems (SoS) can evolve it into a system of autonomous system (SoAS).

Between the Sheets: CH3SO3H Molecules Intercalating B2O3 Layers

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The intercalation compound B6O9·CH3SO3H can be seen as the stabilization of a new B2O3 modification by methanesulfonic acid. The structure elucidation was performed by X‐ray diffraction and solid‐state NMR measurements. The reaction of boric acid and methanesulfonic acid yielded single crystals of B6O9·CH3SO3H (monoclinic, I2/a, Z = 8, a = 873.19(3), b
