Physics of collisionless shocks - theory and simulation [PDF]
, 2015 Collisionless shocks occur in various fields of physics. In the context of space and astrophysics they have been investigated for many decades. However, a thorough understanding of shock formation and particle acceleration is still missing. Collisionless

Uncertainty shocks and business cycle research
Review of economic dynamics (Print), 2020 We review the literature on uncertainty shocks and business cycle research. First, we motivate the study of uncertainty shocks by documenting the presence of time-variation in the volatility of macroeconomic time series.

Review of the History of Economic Thought and MethodologyThis article examines the evolution of Richard Goodwin’s early works, focusing on his repeated attempts to formalize Schumpeterian economic ideas. Drawing from his background in physics, the twentieth-century American macroeconomist developed several ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Fiscal rules and discretion under persistent shocks [PDF]
, 2012 This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time-inconsistent preferences with a present-bias towards public spending.

Input Specificity and the Propagation of Idiosyncratic Shocks in Production Networks
, 2016 This article examines whether firm-level idiosyncratic shocks propagate in production networks. We identify idiosyncratic shocks with the occurrence of natural disasters. We find that affected suppliers impose substantial output losses on their customers,

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Evolutionary Conditions in the Dissipative MHD System Revisited
, 2007 The evolutionary conditions for the dissipative continuous magnetohydrodynamic (MHD) shocks are studied. We modify Hada's approach in the stability analysis of the MHD shock waves.
