Summary: Biomolecular condensation processes are fundamental mechanisms that living cells utilize to organize biomolecules in time and space, leading to the formation of membraneless organelles. Computational methods, including theoretical methods, physics-driven simulations, and data-driven machine learning methods, provide a unique perspective to study biomolecular condensation and offer advantages such as high resolution and scale. This review discusses the recent progress and limitations of these computational approaches and highlights the challenges in understanding the molecular driving forces and biological roles of biomolecular condensation in health and disease.

Summary: Solution-processing of organic light-emitting diode films has potential advantages over vacuum-deposition, but may result in lower device performance. Molecular dynamics simulations were used to study solvent evaporation during solution processing and its effects on charge transport and exciton dynamics.

Summary: An exhaustive computational investigation was conducted on substitutionally doped Co-based POMs with different transition metals and heteroatoms, identifying a promising Cr-based POM with a predicted overpotential of 310 mV for OER. This study establishes linear scaling relationships and leverages electronic effects induced by heteroatoms to efficiently screen potential earth-abundant POMs.

Summary: This study examines the dynamics of Friedmann-Lemaitre-Robertson-Walker cosmologies with an interaction between vacuum and perfect fluid through energy exchange. The focus is on exploring nonsingular configurations, including cyclic and bouncing models. The research demonstrates that both linear and nonlinear combinations of vacuum and fluid energy densities can lead to bouncing and cycling cosmologies.

Summary: This paper investigates the combined KdV-mKdV equation, which is a valuable tool in the study of water waves. Through the bilinear approach, rational solutions and soliton solutions in the determinant form are obtained. The novel idea in this paper allows for free multiparameters in rational solutions, distinguishing it from the Darboux transformation method.

Summary: A machine learning approach was proposed to rationally design polymer composites with desired properties, showing that the effects of nanofiller permittivity and bandgap on breakdown strength and permittivity follow opposite trends. This trade-off can be improved by tailoring the shape, orientation, and distribution of nanofillers.

Summary: Within the Lambda CDM cosmological model, the accurate measurement of the absolute physical density rho Lambda, which is sometimes expressed as the gravitating mass-energy density Lambda or Einstein's cosmological constant, is crucial in testing quantum gravity theories. This study combines various cosmological data and assumes a flat Lambda CDM model to infer the value of the conventional parameter Omega(Lambda)h(2), which corresponds to rho Lambda. The result, rho Lambda = (60.3 +/- 1.3) x10(-31)g/cm(3), is the most precise constraint to date, with a calibration based on CMB temperature. Different values are obtained when using a local distance scale calibration, mainly due to systematic differences in the Hubble constant. Future cosmological parameter studies are suggested to include constraints on the vacuum density.

Summary: The research demonstrates that photocatalytic CO2 reduction in a low vacuum can significantly improve the CH4 yield, showing long-term stability and good cycling performance under such conditions. Enhanced CO2 photoreduction in a low vacuum results from improved accumulation of photogenerated electrons, reduced Brownian movement of gas molecules, and hindered active site-blocking by gas molecules.
