Examination of Afghanistan's Development Traps

open access: yesRegional Science Policy &Practice, EarlyView., 2022
Abstract We examine the factors behind Afghanistan's persistent underdevelopment. Drawing on various theories of development traps operating at the demographic, economic and institutional levels, we seek to assess whether and to what extent their functioning affects Afghanistan's development. To capture the functioning of development traps empirically,

Accessible Text Descriptions for UpSet Plots

open access: yesComputer Graphics Forum, EarlyView.
Abstract Data visualizations are typically not accessible to blind and low‐vision (BLV) users. Automatically generating text descriptions offers an enticing mechanism for democratizing access to the information held in complex scientific charts, yet appropriate procedures for generating those texts remain elusive. Pursuing this issue, we study a single

Design of photonic crystal fibers with flat dispersion and three zero dispersion wavelengths for coherent supercontinuum generation in both normal and anomalous regions

open access: yesResults in Physics, 2021
A photonic crystal fiber (PCF) structure with three-zero dispersion wavelengths (ZDWs) and a flat dispersion curve was designed by adjusting the structural parameters (the diameters of small air holes inserted between standard lattices in the first and ...

Trigonometric Calogero-Moser System as a Symmetry Reduction of KP Hierarchy [PDF]

open access: yesarXiv, 2000
Trigonometric non-isospectral flows are defined for KP hierarchy. It is demonstrated that symmetry constraints of KP hierarchy associated with these flows give rise to trigonometric Calogero-Moser system.

Time‐Varying Interactions Between US–China Political Relation, Flight Frequency, and Inbound Tourism

open access: yesEconomics &Politics, EarlyView.
ABSTRACT This study investigates the dynamics among US–China political relations, flight frequency, and inbound tourism through the utilization of a time‐varying parameter vector autoregression model. As political relations warm, there is a notable uptick in flight frequency between the two nations.

Suppressing robbery, latrocinium, was a priority for Charlemagne, Louis the Pious, Charles the Bald, and Louis II at key political moments. Latrones were conceptualized as ordinary thieves, as highway robbers, and as threats to peace and security. In capitularies, latrocinium was implicitly and explicitly associated with infidelity.
