Flexors of Fingers Ask the patient to make a fist, squeezing their hand around two of your fingers. If the grip is normal, you will not be able to pull your fingers out. Test each hand separately. Extensors of Fingers Ask the patient to open their fist against resistance. Extensors of the Wrist Ask the […]

Sorry, this product is unavailable. Please choose a different combination. Lyophilizers are sophisticated instruments that facilitate the process of lyophilization. Lyophilization or freeze-drying is a precise and costly technique used for the preservation of products, such as astronaut food, biopharmaceuticals, food products, and museum exhibition objects.  Note that during lyophilization, the sample is dehydrated through […]

Catadioptric Telescopes: Introduction While both reflecting and refracting models continued improving over the years, advancements in lens technology outside the field of telescopy led to the development of the catadioptric telescope – a combination of refracting (lenses) and reflecting (mirrors) optics. To provide an example, in 1820, physicist Augustin-Jean Fresnel developed the prominent catadioptric lighthouse […]

ABSTRACT Computer vision (CV) studies involving human participants raise unique ethical and regulatory challenges because video and image data are inherently identifiable. For new investigators, navigating Institutional Review Board (IRB) review can feel opaque and intimidating. This guide offers plug-and-play tools such as boilerplate protocol language, checklists, and case exercises, while clarifying the risks most […]

ABSTRACT Computer vision (CV) methods are increasingly central to both preclinical animal studies and human clinical research. These technologies have the potential to generate high-resolution, continuous, and reproducible measures of behavior that can bridge laboratory findings in rodents with diagnostic or therapeutic applications in humans. However, the translational promise of CV can only be realized […]
