We present a technique to achieve low-velocity to intermediate-velocity collisions between fragile dust aggregates in the laboratory. For this purpose, two vacuum drop-tower setups have been developed that allow collision velocities between <0.01 and ~10 m/sec. The collision events are recorded by high-speed imaging.

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Soft landing of mass-selected ions onto surfaces is a powerful approach for the highly-controlled preparation of novel materials. Coupled with analysis by in situ secondary ion mass spectrometry (SIMS) and infrared reflection absorption spectroscopy (IRRAS), soft landing provides unprecedented insights into the interactions of well-defined species with surfaces.

Equilibrium Rent: The Market for Land

The land is a critical factor of production that is supplied by landowners and rented by producers. For instance, farmers rent land to grow crops. Similarly, a restaurant owner may rent commercial building space to run the restaurant. The price for land is the rental price. Land can be bought, and in that case, the purchase price is the price paid to use that land indefinitely. However, in the current analysis, the rental price of land is used, as it presents a continuous payment similar to the...

This manuscript describes how to create regular bedforms in a flume, visualize flow through the bedforms, and use computer simulations to simulate the hyporheic flow. The computer simulations compare well with the experimental observations. This coupled simulation and experiment is well-suited for both research and educational purposes.
FAQs
The defined drop height establishes a landing condition that shapes the modeled impact response. By holding height constant or changing it between simulations, researchers can examine how joint motion, contact forces, and load transmission through the musculoskeletal system vary across landing scenarios. This controlled comparison helps identify how altered impact conditions affect movement and potential injury risk.
The simulation evaluates how individual body segments interact with the ground during landing and how that interaction transfers load through the musculoskeletal system. Joint motion describes the movement response, while contact forces quantify interaction with the landing surface. Considering these variables together allows researchers to connect external impact with internal mechanical loading rather than examining movement alone.
Joint motion, contact forces, and load transmission provide complementary measures for comparing landing strategies. A change in movement may coincide with a different pattern of ground contact or musculoskeletal loading, so no single variable fully describes the response. Examining these outputs across defined landing conditions supports evaluation of how strategies influence impact behavior and possible injury risk.
Drop-landing Simulation provides a controlled way to compare landing conditions and design changes without relying solely on laboratory experiments or human testing. Researchers can use the modeled response to examine movement and loading under specified scenarios before, or alongside, physical evaluation. This approach supports systematic analysis while reducing dependence on testing every condition directly with people.
A basic workflow begins by specifying the landing height and other landing conditions represented in the model. The simulation then calculates body-segment and ground interactions while tracking joint motion, contact forces, and musculoskeletal load transmission. Researchers compare the resulting variables across conditions or design configurations to evaluate changes in impact response and movement behavior.
The approach is useful when researchers need to evaluate how a prosthetic device, orthotic, or protective-equipment design change affects landing behavior. Comparing simulated joint motion, contact forces, and load transmission can reveal differences in impact response across configurations. These results support design analysis before relying exclusively on laboratory experiments or human testing.
