Light-Controlled Cellโ€“Cell Assembly Using Photocaged Oligonucleotides (open access)

Light-Controlled Cellโ€“Cell Assembly Using Photocaged Oligonucleotides

Article asserts that while techniques that allow one to control the arrangement of cells and direct contact between different cell types have been developed that expand upon simple co-culture methods, specific control over heterojunctions that form between cells is not easily accomplished with current methods, such as 3D cell-printing. In this article, DNA-mediated cell interactions are combined with cell-compatible photolithographic approaches to control cell assembly.

Temporal complexity measure of reaction time series: Operational versus event time (open access)

Temporal complexity measure of reaction time series: Operational versus event time

Article describes how detrended fluctuation analysis (DFA) is a well-established method to evaluate scaling indices of time series, which categorize the dynamics of complex systems. The authors propose treating each reaction time as a duration time that changes the representation from operational (trial number) time n to event (temporal) time t, or X(t).

Object-Oriented Canopy Gap Extraction from UAV Images Based on Edge Enhancement (open access)

Object-Oriented Canopy Gap Extraction from UAV Images Based on Edge Enhancement

Article describes the efficient and accurate identification of canopy gaps is the basis of forest ecosystem research, which is of great significance to further forest monitoring and management. One major limitation of the traditional methods of remote sensing to map canopy gaps is that they cannot finely extract the complex edges of canopy gaps in mountainous areas. The authors proposed an object-oriented classification method that integrates multi-source information.

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations (open access)

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations

Article describes how processes including hot compression, cold compression and subsequent annealing on the structures and properties are investigated and compared. They found that applying pressure up to 10 GPa at the glass transition temperature led to permanent densifications and a dramatic increase of elastic moduli by 90%, while thermal annealing reversed the increase and applying pressure at ambient temperature did not increase the modulus.

Relaxation time approximations in PAOFLOW 2.0 (open access)

Relaxation time approximations in PAOFLOW 2.0

Article presents the implementation of relaxation time approximation models in the calculation of Boltzmann transport in PAOFLOW 2.0 and applies those to model band-structures. In addition, using a self-consistent fitting of the model parameters to experimental conductivity data, the authors provide a flexible tool to extract scattering rates with high accuracy. They illustrate the approximations using simple models and then apply the method to GaAs, Si, Mgโ‚ƒSbโ‚‚, and CoSbโ‚ƒ.
