Summary: An analytical model was proposed to predict the velocity evolution through floating canopies under unidirectional flow. Laboratory experiments showed that the velocity evolution within the canopy interior was influenced by the mean channel velocity, canopy density, and ratio of the height of the free flow region to the flow depth. The proposed model accurately predicted the velocity evolution in floating canopies and could be applied to predict the velocity evolution in the root zones of floating vegetation islands.

Summary: The dynamics of two component bright-bright (BB) solitons passing through different potentials were investigated to achieve unidirectional flow and segregation. A novel phenomenon called Polarity Reversal was observed, and the consistency between analytical and numerical analysis was confirmed through variational calculations.

Summary: The process of characterising how auxin dynamics are controlled is crucial for understanding how auxin plays a role in regulating plant development. Recent studies have shown that auxin diffusion through plasmodesmata influences auxin distributions and subsequently impacts developmental processes such as phototropism, lateral root emergence, and leaf hyponasty. This review highlights how these studies have contributed to our comprehension of auxin dynamics and explores potential future research directions in this field.

Summary: This study calculates the water transport property in the plasmodesmata of a plant cell and finds that wall slippage plays a crucial role in water transportation. By incorporating both the adsorbed boundary layer flow and the intermediate continuum water flow equations, it is discovered that wall slippage in the plasmodesmata dramatically increases the water flow rate.

Summary: In plants, the phloem relies on specialized cells called sieve elements for long-distance distribution of photosynthetic products. This study identifies PLL12 as a critical gene for sieve element differentiation and suggests its vital role in pectin remodeling. While short distance symplastic diffusion is unaffected, PLL12 appears to act as a regulator for local pectin degradation during sieve pore maturation.

Summary: This study investigates the unidirectional drying of water in closed capillaries. It is found that the way the capillary is closed significantly affects the drying process. When the capillary is closed at one end, the drying process follows Stefan's equation. However, when the capillary is connected to a fluid reservoir, the water plug evaporates at a constant rate while the water-air meniscus remains pinned at the exit. By increasing the viscosity of the fluid in the reservoir or connecting the capillary end to a solidifying fluid, a transition from a constant-rate drying to diffusion-driven drying can be observed.

Summary: The unidirectional drying process of water in cylindrical capillaries, which was previously thought to be vapor diffusion-controlled with a square root of time kinetics, is actually influenced by the way the capillary is closed. Experimental results show that when the capillary is closed with a solid material, Stefan's solution is recovered; however, when it is connected to a fluid reservoir, the water plug evaporates at a constant rate with the water-air meniscus remaining pinned at the exit. The presence of a liquid reservoir and capillary pumping effect increases the flow of the water plug towards the evaporation front, leading to a drying process that is substantially faster than predicted by Stefan's equation. Increasing the viscosity of the fluid in the reservoir or connecting the capillary end to a solidifying fluid like epoxy glue can induce a transition from constant-rate evaporation to diffusion-driven evaporation.

Summary: Motivated by the drag-based propulsion of crinoids, the authors investigated the shape reconfiguration of a feather-like elastic structure. Through theoretical and experimental analysis, they successfully predicted the drag force and three-dimensional reconfiguration of the elastic structure during both power and recovery strokes. They proposed a dimensionless speed and a reconfiguration number to characterize the effect of reconfiguration on drag force reduction.

Summary: The electrical current blockade caused by a peptide or protein passing through a nanopore can be used as a fingerprint for molecule identification in biosensor applications. This study presents an enzyme-free method for slow, unidirectional transport of full-length proteins through nanopores. By using a chemically resistant biological nanopore, alpha-hemolysin, and a high concentration guanidinium chloride buffer, protein transport can be propelled by electroosmotic effect. The translocation dynamics of proteins resemble that of single-stranded DNA, and single-translocation events contain enough information for orientation and identity determination with over 90% accuracy using a supervised machine-learning classifier.

Summary: A dog's nose allows air to flow in a unidirectional path, creating stagnant zones of air that contribute to its physical memory. In this study, experiments and simulations were conducted to compare the effects of bidirectional and unidirectional flows on odor detection. The unidirectional setting exhibited a slow return to baseline levels, indicating memory effects. The findings suggest that these memory effects can potentially enhance the sensitivity and utility of electronic noses.

Summary: We propose a water pump that transports water molecules through nanochannels by utilizing spatially asymmetric thermal fluctuations. The pump achieves unidirectional water flow without osmotic pressure by exploiting hysteresis in the cyclic transition between wetting and drying states. Our study demonstrates that various types of fluctuations, including white, Brownian, and pink noises, affect the water transport process. The proposed pump operates through fast switching of open and close states to inhibit channel wetting in the presence of white noise, while pink and Brownian noises generate high-pass filtered net flow.

Summary: This study reveals that calcium waves in plants are mediated by diffusion and bulk flow of amino acid chemical messengers. Wounding triggers the release of amino acids which activate calcium-permeable channels. Additionally, it was found that calcium waves alone cannot initiate all systemic defense responses, suggesting the importance of mobile chemical messengers in complex systemic signaling in plants.

Summary: The study evaluates the narrow escape problem as a framework for describing intercellular transport, introducing a volumetric adjustment factor to estimate escape times and providing results for a range of cell sizes and diffusivities. The approach can be extended using recent results on multiple trap problems to account for different plasmodesmata distributions with varying apertures.
