Research on delay upper bound analysis based on network calculus for LEO satellite network
Tongxin xuebaoIt’s essential to achieve reliable transmission by accurately characterizing the delay upper bound in space-air-ground integrated network (SAGIN). Based on deterministic network calculus and time-aware shaping (TAS) mechanism in time-sensitive networking

Creativity and Innovation Management, EarlyView.ABSTRACT Creativity and innovation are often understood as the result of a complex interplay of hierarchical factors, such as national, regional and firm characteristics, or between organisational and individual factors. While recent applications of qualitative comparative analysis (QCA) have begun to model such configurational links, their ...

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Economic Inquiry, Volume 63, Issue 2, Page 424-440, April 2025.Abstract Eaton, Kortum, and Kramarz (2011) (EKK) discovered empirical patterns from French manufacturing firms that a baseline firm heterogeneity model could not explain. The authors proposed and estimated a model that closely matches the patterns observed in French data.

Building a Potemkin village in occupied China: Japan's wartime system of linked trade, 1939–43
The Economic History Review, EarlyView.Abstract The paper discusses the novel but little‐known exchange rate system of Japanese‐occupied North China during the Second Sino‐Japanese War, in which exporters were given the right to import in the form of a piece of yellow paper, which could be sold in the secondary market.

The Legacy of Policy Inaction in Climate‐Growth Models
International Economic Review, EarlyView.ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

A Comparative Review of Specification Tests for Diffusion Models
International Statistical Review, EarlyView.Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Eigenvalue Problem in Min-Plus Algebra
Eigenvalue Problem in Min-Plus Algebra本論文では,Min-Plus代数における行列の固有値問題を取り上げる.Min-Plus代数とは様々な数学の分野で研究がされているベキ等な半環構造を持つ代数系の1つである.Min-Plus代数では一般の線形代数における様々な性質や定理がそのまま従うように思えるが,検証はされていない.そこで我々はこのMin-Plus代数における行列の固有値を調べ,何らかの特徴付けができないかを考えた.そしてMin-Plus代数における重み付き隣接行列の固有値が,その行列で実現できる重みの付いた有向グラフ(ネットワーク)の閉路平均重みと対応していることがわかり,それを証明することができた.しかし,ネットワークの全ての閉路に対して,その平均重みが重み付き隣接行列の固有値として現れるかについてはまだわかっておらず ...

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes
International Statistical Review, EarlyView.Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.
