Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

UK Forecasts of Annual GDP: Their Accuracy and the Information Categories Underlying Their Revisions

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Policy makers are concerned with the accuracy of GDP forecasts and want to understand the reasons for the revision of forecasts. We study these issues by examining forecasts of annual UK GDP growth by a panel of agents, published monthly by HM Treasury. We focus on two main issues: the developing accuracy of the group‐mean forecast as horizons

Minimum Wages, the Earned Income Tax Credit, and Mental Health Around Pregnancy

open access: yesHealth Economics, EarlyView.
ABSTRACT This study estimates the effects on perinatal mental health of the state's minimum wage and earned income tax credit (EITC), controlling for other policies and state‐level factors. Using data from the Pregnancy Risk Assessment Monitoring System for 2012–2018 births we find robust evidence that minimum wages and EITC levels reduce depression ...

Alternative Price Dynamics and Valuation of Flexible Strategies

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT In this article, we study the optimal operational strategy of production projects. We investigate different underlying price models and determine the optimal barriers of transition to suspension, recovery, or irreversible abandonment of productive activity.

Forecasting Natural Gas Prices in Real Time

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...

Mixed‐mode membrane chromatography: mechanistic‐modeling‐based optimization and scale‐up of antibody charge variant separation using a novel membrane adsorber

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Efficient manufacturing of complex biopharmaceuticals increasingly relies on innovative downstream processing strategies. Membrane chromatography offers a promising alternative to resin‐based systems by enabling high‐throughput separations at elevated flow rates. Typically used in flow‐through mode, its industrial applications range

Techno‐economic analysis for hydroxy acids production from waste cellulose via alkaline digestion

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Alkaline digestion offers a promising route for converting low‐grade cellulosic wastes into valuable hydroxy carboxylic acids (HAs). However, the feasibility of producing HAs at process scale, particularly the influence of reactor design on product yields, energy demand, and production costs, remains less explored.
