Line launchers are devices that have been used for centuries for maritime rescue operations. The typical implementation is the use of a gun, rocket, or mechanical launcher to hurl a grappling hook or flotation buoy for stranded ships and overboard sailors. Microgravity offers analogous use cases, ranging from microsatellite operations to space debr...
Neuromodulation is used to treat neurological disorders. Focused ultrasound can deliver acoustic energy to local regions of the brain, including deep brain structures. In addition, it is possible to induce the activation or inhibition of nerves through parameter adjustments of focused ultrasound. Laser-generated focused ultrasound (LGFUS) has demon...
Mechanical launchers have played important roles in warfare and industry throughout human history. The Jeju Historical Machines Collection (JHMC) is a collection of 3D models of historical mechanical launchers and tools for experimental archeology, citizen science, and reconstructive research. The collection is sorted into three categories: crossbo...
A possible concept for a self-contained optoelectronic microcraft.
6 Korea 7 * These two writers contributed equally. Abstract 18 Drowsiness is a leading cause of traffic and industrial accidents, costing lives and productivity. 19 Electroencephalography (EEG) signals can reflect awareness and attentiveness, and low-cost 20 consumer EEG headsets are available on the market. The use of these devices as drowsiness 2...
Controlling the kinetic energy of a projectile at a desired distance has always been key to several scientific, industrial, medical, and other applications. Scientific applications include the distance biopsy of animals and implantation of tracking chips. Industrial applications include modulating velocity and thickness of ferrofluid dispositions i...
Due to patient mortality and sequelae from extracorporeal membrane oxygenation (ECMO), alternative approaches to long-term extracorporeal life support are necessary. While blood pumps, vascular assistive devices, and total artificial hearts have existed for decades, reoxygenation of blood presents a complex and imperative challenge to extracorporea...
A non-invasive, brain-to-brain interface (BBI) requires precision neuromodulation and high temporal resolution as well as portability to increase accessibility. A BBI is a combination of brain-computer interface (BCI) and computer-brain interface (CBI). The optimization of BCI parameters has been extensively researched, but CBI has not. Parameters...
p class="VARAbstract">Preservation of historical weapons requires continual and careful maintenance. Digital three-dimensional (3D) scanning can assist in preservation and analysis by generating a 3D computer model. New Zealand presents a special case for historical preservation, owing to the rapid import of European goods in a culture previously u...
The osteotome was a hand-cranked chainsaw designed in 1830 by the German surgeon Bernhard Heine. Before Heine, surgeons used crude, manual tools, such as hammers, chisels, and handsaws. The osteotome was among the first mechanical tools used in orthopedic surgery, and it preceded the later use of the motorized chainsaw for woodcutting. Due to the s...
Some limitations and hurdles felt hardly feasible practically,(though hypothetically feasible) are overcomed by merging the T-HAVEN with FPB
Objective:
EEG spindles, narrow-band oscillatory signal bursts, are widely studied biomarkers of subject state and neurological function. Most existing methods for spindle detection select algorithm parameters by optimizing agreement with expert labels. We propose a new framework for selecting algorithm parameters based on stability of spindle pro...
Current synthetic biology research is focused on the molecular level, but viable artificial organs require a systematic framework for integration, sustenance, and coordination. While synthetic microbiology and tissue engineering are fundamental components, a higher level view of integration is often non-existent in the literature. A relevant resear...
Biosignal classification systems often have to deal with extraneous features, highly imbalanced datasets, and a low SNR. A robust feature selection/reduction method is a crucial step in this process. Sets of artificial data were generated to test a prototype EEG-based microsleep detection system, consisting of a combination of EEG and 2-s bursts of...
Digital currencies, such as Bitcoin and its derivatives (known as altcoins), represent at different approach to money that simultaneously allows entirely novel possibilities. With the automation destroying entire economic sectors, the universal basic income (UBI) may become an essential tool for continued economic prosperity and social stability. T...

I am working on a linear magnetic accelerator for impact testing, with a few unique requirements. I'm looking to accelerate a 2mm chromium steel ball bearing up to 100 m/s with the least amount of power/energy requirements. Should I try a multi-stage design? Or a single long coil? This device needs to be moved around and discharge 1-3 projectiles in succession, so might adapting a hobbyist coilgun design be sufficient?
I looked over your summary for a cell-free isolated head viability model, and I recall a few issues. How might you account for infection, especially if lymph nodes and bone marrow stem cells have been substantially increased? Likewise, ECMO circulation in hospitals today kills half the patients it's hooked up to, and results in neurological damage on the rest. Also, cutting the spine results in neurological atrophy and degeneration up to the sensorimotor cortex.
I believe that each of these issues is surmountable, but blood and bone marrow are big ones. ECMO can be improved by use of an adapted blood pump and respirator/artificial lung, controlled in a similar way to the vagus nerve. Likewise, neurostimulation via a biocompatible implant (e.g., carbon nanotube-based microelectrode array) could forestall the degeneration and interface directly with neuroprosthetics. What are your thoughts?
