Topology Unveiled: A New Horizon for Economic and Financial Modeling

open access: yesMathematics
Sinceits introduction in the 19th century to address geometric problems, topology as a methodology has undergone a series of evolutions, encompassing branches of geometric topology, point-set topology (analytic topology), algebraic topology, and ...

A Study of the Role of Government in Income and Wealth Distribution by Integrating the Walrasian General Equilibrium and Neoclassical Growth Theories [PDF]

open access: yesInterdisciplinary Description of Complex Systems, 2014
This paper proposes a growth model of heterogeneous households with economic structure, wealth accumulation, endogenous labour supply, and tax rates. The paper is focused on effects of redistribution policies on income and wealth distribution, economic ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Macroeconomic Theory: A Dynamic General Equilibrium Approach [PDF]

open access: yes
Macroeconomic Theory is the most up-to-date graduate-level macroeconomics textbook available today. This book truly offers something new by emphasizing the general equilibrium character of macroeconomics to explain effects across the whole economy, not ...

The Passage of Time, Capital, and Investment in Traditional and in Recent Neoclassical Value Theory

open access: yesŒconomia, 2017
With the shift from traditional analyses where capital is a single value factor of variable ‘form’ to the neo-Walrasian versions, general equilibrium theory has encountered new problems pointed out by P.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Nonequilibrium Entropy in a Shock

open access: yesEntropy, 2017
In a classic paper, Morduchow and Libby use an analytic solution for the profile of a Navier–Stokes shock to show that the equilibrium thermodynamic entropy has a maximum inside the shock.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Intertemporal General Equilibrium and Monetary Theory [PDF]

open access: yes, 2001
Theory is often at odds with the thinking and practice of monetary authorities. A confrontation of this situation is timely. General equilibrium theory serves to check the consistency of models and to bring out some of their properties. Surprisingly, an enquiry into monetary theory from the perspective of general equilibrium leads to conclusions that ...
