Magnetohydrodynamic instabilities in stellar radiative regions. I. Linear study of shear-driven instabilities
V. Durepaire, L. Petitdemange, K. Belkacem +4
This paper is the first in a series investigating magnetohydrodynamic instabilities that may contribute to angular-momentum transport and magnetic-field evolution in stellar radiat…
The Spectral Topology of Global Imbalances:A Graph-Theoretic Framework for Systemic Risk in the Balance of Payments
Chandrasekhar Gokavarapu, Sanjeev Kumar Chejarla, Balayya Rajana +2
We model global balance-of-payments linkages as a directed weighted exposure network and study systemic fragility through the spectrum of the associated operators. From a signed bi…
Almost fifty years of Metsähovi solar observations on 37 GHz with recovered digitised historical maps
Sami Kivistö, Frederick Gent, Merja Tornikoski +2
Context. Aalto University Metsähovi Radio Observatory has collected solar intensity maps for over 45 years. Most data coverage is on the 37 GHz frequency band, tracking emissions p…

Sequential Monitoring of Changes in Housing Prices
Lajos Horváth, Zhenya Liu, Shanglin Lu
We propose a sequential monitoring scheme to find structural breaks in real estate markets. The changes in the real estate prices are modeled by a combination of linear and autoreg…
A Model for Counterparty Risk with Geometric Attenuation Effect and the Valuation of CDS
Yunfen Bai, Xinhua Hu, Zhongxing Ye
In this paper, a geometric function is introduced to reflect the attenuation speed of impact of one firm's default to its partner. If two firms are competitions (copartners), the d…
