Honeybee flight dynamics and pair separation in windy conditions near the hive entrance

New Journal of Physics, 2023
Animals and living organisms are continuously adapting to changes in their environment. How do animals, especially those that are critical to their ecosystem, respond to rapidly changing conditions in their environment?

Honeybees modify flight trajectories in turbulent wind

New Journal of Physics, 2022
In windy conditions, the air is turbulent. The strong and intermittent velocity variations of turbulence are invisible to flying animals. Nevertheless, flying animals, not much larger than the smallest scales of turbulence, manage to maneuver these ...

Laplacian Pattern Formation [PDF]

Europhysics News, 1988
The formation of snowflakes, viscous fingers and electrodeposits is governed by analogous equations : these structures are all Laplacian patterns. In this paper we review model experiments and computer simulations which are widely used to study diverse morphologies resulting from the motion of unstable interfaces.

Spiral- and scroll-wave dynamics in mathematical models for canine and human ventricular tissue with varying Potassium and Calcium currents

Physics Open, 2022
We conduct a systematic, direct-numerical-simulation (DNS) study, in mathematical models for ventricular tissue, of the dependence of spiral- and scroll-wave dynamics on GKr, the maximal conductance of the delayed rectifier Potassium current (IKr ...

The effects of inhomogeneities on scroll-wave dynamics in an anatomically realistic mathematical model for canine ventricular tissue

Physics Open, 2021
Ventricular tachycardia (VT) and ventricular fibrillation (VF) are lethal rhythm disorders, which are associated with the occurrence of abnormal electrical scroll waves in the heart.

Pattern formation today

The International Journal of Developmental Biology, 2009
Patterns are orders embedded in randomness. They may appear as spatial arrangements or temporal series, and the elements may appear identical or with variations. Patterns exist in the physical world as well as in living systems. In the biological world, patterns can range from simple to complex, forming the basic building blocks of life.

Elastic Instability Triggered Pattern Formation [PDF]

, 2009
Recent experiments have exploited elastic instabilities in membranes to create complex patterns. However, the rational design of such structures poses many challenges, as they are products of nonlinear elastic behavior.

Divergent Deborah number-dependent transition from homogeneity to heterogeneity

Nature Communications, 2023
Heterogeneous structures are ubiquitous in natural organisms. Native heterogeneous structures inspire many artificial structures that are playing important roles in modern society, while it is challenging to identify the relevant factors in forming these
