Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Task‐Oriented Path Planning Towards Autonomous Sensor Network Deployment in Rainforest Canopies
An informative path planner for drone‐based deployment of wireless sensor networks in rainforest canopies is presented, addressing key challenges in large‐scale biodiversity monitoring. By integrating canopy surface detection with connectivity‐aware sampling under strict flight constraints, the approach enables efficient and reliable aerial sensor ...

Systematic Exploration of 3D Concrete Printing Parameters for Conformal Printing on Sloped Surfaces
A conformal slicing algorithm is developed for robotic 3D concrete printing (3DCP) on sloped surfaces as a first step toward printing slab‐on‐grade foundations on uneven terrain. Systematic experiments quantify the effects of nozzle speed, extrusion rate, and toolpath direction on filament dimension and stability.

Thick slice and thin slice teaching evaluations
Social Psychology of Education, 2009Student-based teaching evaluations are an integral component to institutions of higher education. Previous work on student-based teaching evaluations suggest that evaluations of instructors based upon “thin slice” 30-s video clips of them in the classroom correlate strongly with their end of the term “thick slice” student evaluations.

Spread of activity in thick cortical slices
Brain Research, 1984Slices of the hamster cerebral cortex 700-800 micron thick have been demonstrated to be viable when maintained in a bath perfused with oxygenated CSF at 30 ml/min. In such thick slices activity has been shown to spread over both hemispheres following stimulation of the corpus callosum; and seizure activity, suggestive of epilepsy, can be induced by the

Cytokeratin demonstration in thick breast tissue slices
The Histochemical Journal, 1997Tissue slices (500 to 1000 microns thick) of archival formalin-fixed, paraffin-embedded breast tissue were immunostained by a cytokeratin antibody (MNF116) using a streptavidin-biotin complex procedure. The technique requires prolonged exposure of tissue slices to the reagents. Use of the detergent Triton X-100 facilitated penetration of high molecular

Slice‐thickness artifacts in gray‐scale ultrasound
Journal of Clinical Ultrasound, 1981AbstractWe have become increasingly aware of the presence of a type of image artifact normally appearing in anechoic areas (eg, cyst, bladder, gallbladder) and giving the appearance of “sludge” or “debris.” These artifactual echoes may be caused by the fact that the finite width of the transducer beam pattern produces a finite thickness of the patient ...

Slice thickness reduction by partial overlapping presaturation
Magnetic Resonance in Medicine, 1992AbstractWe present a new approach to slice thickness reduction that does not require strengthening the selection gradient or increasing the RF pulse duration. The basis of the approach is to employ a thick slice and suppress a portion of its width, thereby forming a thin slice.
