Compact heat exchangers – Design and optimization with CFD
International Journal of Heat and Mass Transfer, 2020 Heat transfer is one of the key aspects of machineries, devices and industrial processes for maintaining their functionality and also for achieving better product quality. Hence, heat exchangers of different types and sizes are used in these applications

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Asymptotics of the heat exchange
Journal of Functional Analysis, 2004 If \(K\subset \mathbb R^{m}\) is a compact subset, we set \(E_{K}(t) = \int_{\mathbb R^{m}\setminus K} u(x,t)\,\roman dx\), where \(u\) is the (unique) weak solution to the heat equation \(\partial_{t}u = \Delta u\) in \((\mathbb R^{m}\setminus K)\times \mathbb R_+\) with initial condition \(u(\cdot,0) = 0\) and boundary condition \(u=1\) on \(\partial

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
