PACKMOL is a widely utilized molecular modeling tool within the computational chemistry community. However, its tremendous advantages have been impeded by the longstanding lack of a robust open-source graphical user interface (GUI) that integrates parameter settings with the visualization of molecular and geometric constraints. To address this limitation, we have developed PACKMOL-GUI, a VMD plugin that leverages the dynamic extensibility of the Tcl/Tk toolkit.

Molding has been widely used to manufacture thermoset composite structures in the aerospace and automotive industries owing to its efficiency in reducing the number of parts and the manufacturing cost. For such molded composite parts, the degree-of-cure curve is generally used to evaluate the solidification of the resin. Nevertheless, in simulation of cure is not the cure model itself, but rather knowing the initial conditions such as fiber volume fraction, initial curing degree, convective boundary conditions etc.

To analysis repair function of mucin-2(MUC2) and glycoprotein particles on the tight junction protein of uterus under bacterial endotoxins. In this experiment, we showed that the thicker mucus layer of the uterus is used to prevent the translocation of endotoxin at 21d postdelivery. When endotoxin acts on the uterus to thin its mucous layer, the cells in the lamina propria of the uterus secrete a large number of glycoprotein particles at 27d postdelivery.

Graphene plasmons exhibit significant potential across diverse fields, including optoelectronics, metamaterials, and biosensing. However, the exposure of all surface atoms in graphene makes it susceptible to surrounding interference, including losses stemming from charged impurity scattering, the dielectric environment, and the substrate roughness. Thus, designing a dielectric environment with a long lifetime and tunability is essential.

Article Synopsis
  • Researchers developed a nanomedicine system called HA-P-L, which incorporates a drug that inhibits tumor growth and is designed to effectively cross endothelial layers and deliver treatment to tumor cells.
  • The HA-P-L system maintains its structural integrity during transcytosis, allowing it to release the drug effectively inside tumor cells while avoiding degradation in endothelial cells.
  • Experiments showed that HA-P-L had better cellular uptake and retention in tumors compared to other formulations, leading to improved efficacy in suppressing tumor growth in both high and low permeability models.

Surface plasmon polaritons and phonon polaritons offer a means of surpassing the diffraction limit of conventional optics and facilitate efficient energy storage, local field enhancement and highsensitivity sensing, benefiting from their subwavelength confinement of light. Unfortunately, losses severely limit the propagation decay length, thus restricting the practical use of polaritons. While optimizing the fabrication technique can help circumvent the scattering loss of imperfect structures, the intrinsic absorption channel leading to heat production cannot be eliminated.

For an infectious disease such as COVID-19, we present a new four-stage vaccination model (unvaccinated, dose 1 + 2, booster, repeated boosters), which examines the impact of vaccination coverage, vaccination rate, generation interval, control reproduction number, vaccine efficacies and rates of waning immunity upon the dynamics of infection. We derive a single equation that allows computation of equilibrium prevalence and incidence of infection, given knowledge about these parameters and variable values. Based upon a 20-compartment model, we develop a numerical simulation of the associated differential equations.
