We describe a novel methodology for creating naturalistic 3-D objects and object categories with precisely defined feature variations. We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic objects.

Source: Corey Burns, Tamara M. Powers, Department of Chemistry, Texas A&M University Paddlewheel complexes are a class of compounds comprised of two metal ions (1st, 2nd, or 3rd row transition metals) held in proximity by four bridging ligands (most commonly formamidinates or carboxylates) (Figure 1). Varying the identity of the metal ion and the bridging ligand provides access to large families of paddlewheel complexes. The structure of paddlewheel complexes allows for metal-metal bonding,...

There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision...

Multiple Object Tracking

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...
FAQs
Imaging helps clinicians determine a metallic object’s location, depth, size, and relationship to nearby anatomical structures before attempting extraction. This information supports selection of a safer access route and helps identify situations in which direct instrument removal may be inappropriate. Accurate localization can also reduce the likelihood of leaving fragments behind or causing additional tissue injury during the procedure.
These characteristics influence both accessibility and the potential for complications. A deeply embedded object or one positioned near important structures may require a different approach than a more accessible object. Clinicians assess these factors to balance successful extraction against risks such as tissue injury, obstruction, infection, bleeding, or retained fragments, then choose an approach suited to the clinical circumstances.
The approaches differ mainly in how clinicians reach and extract the object. Endoscopic retrieval provides access through an endoscope, surgical extraction uses an operative approach, and carefully controlled instrument removal may address an accessible object. The choice depends on the object’s location, depth, size, and surrounding structures. Each option requires planning that addresses safe access and complete removal.
The process begins with assessment of the object and its anatomical position, often supported by imaging. Clinicians then select an extraction approach and determine whether anesthesia is needed. After removal, they assess the site, provide wound care when appropriate, and monitor for bleeding or retained fragments. This sequence links procedural planning with post-procedure safety and recovery.
Anesthesia may be required when the selected removal approach could cause discomfort or needs controlled conditions. Wound care becomes relevant when extraction leaves an affected tissue site requiring attention during recovery. Clinical follow-up also includes monitoring for bleeding and checking for retained fragments. These measures help detect problems after the object has been removed and support safe healing.
The clinical context determines the main concern and the suitable access route. Swallowed objects may require endoscopic retrieval, whereas embedded objects may call for carefully controlled instrument removal or surgical extraction, depending on depth and location. Objects introduced accidentally into the body are evaluated in the same structured way, with attention to nearby structures and possible tissue complications.
