BSDEs and log-utility maximization for Lévy processes

open access: yesModern Stochastics: Theory and Applications, 2019
In this paper we establish the existence and the uniqueness of the solution of a special class of BSDEs for Lévy processes in the case of a Lipschitz generator of sublinear growth.

Host Cell Protein Challenges in Antibody Processing: Insights Into Persistence and Mitigation Strategies

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.

Whole‐Cell Production of Resolvin E2 and 17R‐Resolvin D5 by a Double‐Oxygenating 15S‐Lipoxygenase With 5S‐Lipoxygenase Activity From Pseudobdellovibrionaceae bacterium

open access: yesBiotechnology and Bioengineering, EarlyView.
A recombinant whole‐cell platform expressing a bacterial 15S‐LOX exhibiting 5S‐LOX activity enabled the stereoselective production of RvE2 and 17R‐RvD5 from 18R‐HEPE and 17R‐HDHA, achieving final concentrations of 0.57 mM and 1.48 mM from 4.0 mM substrates, respectively, under optimized conditions.

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

open access: yesBiological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Environmental Regulation at the Crossroads: A Review of Catalysts and Barriers in Circular Economy Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid growing resource pressures, environmental regulation plays a critical role in enabling the transition to a circular economy (CE). This study conducts a systematic literature review to synthesize how different regulatory approaches—command‐and‐control, market‐based, voluntary, and reflexive—affect CE transitions across economic and ...

On the reducibility of affine models with dependent Lévy factors

open access: yesModern Stochastics: Theory and Applications
The paper is devoted to the study of the short rate equation of the form \[ \text{d}R(t)=F(R(t))\text{d}t+{\sum \limits_{i=1}^{d}}{G_{i}}(R(t-))\text{d}{Z_{i}}(t),\hspace{1em}R(0)={R_{0}}\ge 0,\hspace{3.33333pt}t\gt 0,\] with deterministic functions

Ruin Time and Severity for a Lévy Subordinator Claim Process: A Simple Approach

open access: yesRisks, 2013
This paper is concerned with an insurance risk model whose claim process is described by a Lévy subordinator process. Lévy-type risk models have been the object of much research in recent years. Our purpose is to present, in the case of a subordinator, a
