DNA Molecular Computing with Weighted Signal Amplification for Cancer miRNA Biomarker Diagnostics

Advanced Science, EarlyView.
A molecular computing approach is presented with weighted signal amplification. Polymerase‐mediated strand displacement is employed to assign weights to target miRNAs, reflecting the miRNAs’ diagnostic values, followed by amplification of the weighted signals using localized DNA catalytic hairpin assembly.

Ohmic Response in BiFeO3 Domain Walls by Submicron‐Scale Four‐Point Probe Resistance Measurements

Advanced Electronic Materials, EarlyView.
Lateral transport measurements of multiferroic domain walls (DWs) in BiFeO3 thin films employing a novel, lithography‐free method are presented. Using a submicron‐scale multi‐point probe (MPP), ohmic DW conduction behavior is demonstrated, including the first collinear, four‐point resistivity value of a single DW, free of contact resistances.

Homogeneous Volatility Bridge Estimators [PDF]

Quantitative Finance 14 (1), 87-89 (2013), 2009
We present a theory of homogeneous volatility bridge estimators for log-price stochastic processes. The main tool of our theory is the parsimonious encoding of the information contained in the open, high and low prices of incomplete bridge, corresponding to given log-price stochastic process, and in its close value, for a given time interval.

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

Advanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Chemical Bonds Containing Hydrogen: Choices for Hydrogen Carriers and Catalysts

Angewandte Chemie, EarlyView.
Hydrogen carriers utilizing B─H, C─H, N─H, and O─H bonds are evaluated for their potential in hydrogen storage and release. Key candidates such as methanol, ammonia, and formic acid are examined with a focus on critical factors influencing performance, including the nature of chemical bonds, reaction pathways, and catalytic processes.

Computational method for probability distribution on recursive relationships in financial applications [PDF]

arXiv, 2019
In quantitative finance, it is often necessary to analyze the distribution of the sum of specific functions of observed values at discrete points of an underlying process. Examples include the probability density function, the hedging error, the Asian option, and statistical hypothesis testing.

Reusable ReOx‐Pd/CeO2 Catalyst with Low Metal Surface Concentration for Efficient Consecutive Deoxydehydration and Hydrogenation of Vicinal OH Groups

Advanced Energy and Sustainability Research, EarlyView.
Less metal, more distance! The ReOx‐Pd/CeO2 catalyst, an active heterogeneous catalyst for the consecutive deoxydehydration and hydrogenation of vicinal diol, suffers a gradual loss of activity throughout its use due to the polymerization of monomeric ReOx active species.

Binding Energy Partition of Promising IRAK‐4 Inhibitor (Zimlovisertib) for the Treatment of COVID‐19 Pneumonia

ChemPhysChem, Volume 23, Issue 24, December 16, 2022., 2022
The electronic energy was divided throughout the Fragment‐Based Drug Design (FBDD) process of the drug Zimlovisertib using the Interacting Quantum Atoms method. The authors could thereby establish the suitability of the chemical modifications in each step of FBDD, providing a valuable test through an FBDD process.
