Training Swimwear Garment to Address Injury Risk Factors

Such … moreSwimming-related injuries, including shoulder injuries, are common, with most injuries occurring during training sessions. Such injuries happen for various reasons, including lengthy training sessions, improper stroke movement/patterns, poor posture, and swimmer fatigue. Swimwear manufacturers have focused on addressing these issues by developing technical/high-tech swimsuits for short-duration competitive swimming rather than for extended use during training sessions. In addition to using high-tech swimsuits during competition, other injury prevention/recovery techniques include modifying training routines by resting/decreasing session length, using Kinesio taping of the shoulders, physical therapy, and wearing posture shirts. These methods can increase the amount of training required to maintain peak performance and may only address one cause of an injury (e.g., Kinesio tapes only address shoulder posture, not overall swimmer posture). Researchers at UC Davis have developed a swimwear garment that can be worn over traditional swimwear or against the skin. The swimwear garment helps to improve form and positioning in the water to reduce injuries and allows injured swimmers to continue training while recovering from their injury. The swimwear garment is focused on addressing injury risk factors by promoting core muscle activation, raising a swimmers body position in the water, improving shoulder posture to help reduce the possibility of injury. and assisting swimmers with posture and maintaining correct form. less

MAGNETIC RESONANCE ELASTOGRAPHY SYSTEM FOR THE PROSTATE

MRE has been used to image the prostate using a both abdominal and transperineal drivers to apply rapidly varying pressure to the perineum in order to produce the necessary compression waves. The transperineal driver provides a cylinder attached to a patient table with an internal movable piston driven pneumatically by a remote pressure source operating at about 45 Hz. Resulting MRE images produced using this driver suffer from poor quality due in part to patient motion.\r\n\r\nUW-Madison researchers have developed a lightweight, disposable, trans-perineal passive diver for magnetic resonance elastography. The device includes an anchoring mechanism that allows the passive driver to be secured firmly in place. The transperineal approach brings the passive driver much closer to the prostate and removes the intervening structures that interfere with wave propagation from the abdominal/pelvic wall approach. Active driver frequency can be increased (from ~60Hz to 100-110Hz) which significantly improves image resolution. The anchoring mechanism firmly fixes the passive driver to the perineum thereby mitigating patient-related motion. This approach improves image quality and reproducibility (which is a critical need for image-based biomarkers). less

Background:
Phase change memory (PCM) is a type of non-volatile RAM that stores data by changing the state of the material used, back and forth between amorphous and crystalline states. PCM has emerged in recent years by offering great potential for future non-volatile solid-state memory. Multilevel storage (storage of multiple bits in a memory cell) and storage of analog data comprise a key factor for the competitiveness of PCM technology in the nonvolatile memory market. Multilevel storage techniques can increase storage density and reduce energy consumption in PCM devices. Analog processing and storage are considered disruptive emerging technology for neuromorphic computer applications. However, accurately controlling the phase transitions as well as understanding the underlying switching mechanisms are still hindering the wider adoption of PCM multi-level memory technology.
Technology Overview:
This technology is a novel group III-Antimonide phase change memory (PCM) materials that comprise likely candidates for multilevel and analog PCM devices. The technology uses thin films of group Ill-Sb alloys (AISb, GaSb and AIGaSb) deposited on TiN or W plugs in a Si/SiO2 structures to form mushroom-type PCM cells. The technology provides improved scalability, reduced complexity and cost, multilevel data read/write with high data retention, and endurance. These features will enable the fabrication of PCM devices that meet the requirements for distributed self-learning hardware (such as smart sensors) and neuromorphic fabrics for artificial intelligence and big data analysis.

An important method … more Renewable hydrogen is necessary to enable a transition to clean fossil-fuel free energy. An important method of producing clean hydrogen is electrolysis of water and one key component of such electrolyzers is the PEM.In order to commercially deploy electrolyzers it is necessary to design the appropriate configuration of the PEM.However, PEMs are difficult to model because complex fluid dynamics and chemical reactions depend on porosity, thickness, pore size, and other factors.This software allows for the accurate modeling of the porous transport layer and the channel-land structure of PEMs and thus allows manufacturers to design high-performance electrolyzers. less

The design repurposes the existing hardware mechanisms for translating memory addresses to also provide translation for internal storage addresses, namely the IOMMU.
While other technologies exist to allow direct device access, this innovation does not allow access to files (only raw devices) and does not support shared access from multiple applications. First, a kernel maps a file into user space at a “File Virtual Address” (FVA) and creates augmented page table entries for this address. Then the user process accesses the device directly using instructions along with FVA and a process address space ID. The device employs IOMMU to translate FVA to Logical Block Addresses (LBA); translation fails if user doesn't have access permissions. less

TRANSFER OF NANOSTRUCTURES USING CROSSLINKABLE COPOLYMER FILMS

To meet the demands of most of these applications, nanoribbons narrower than 5 nm are desirable, as they can have technologically relevant bandgaps arising from quantum confinement effects.\r\n\r\nUW researchers have developed a method for transferring sub-10 nm width graphene nanoribbons to other substrates with high yields. The key to the improved method is the use copolymer polymerized from non-crosslinking monomers and comonomers.. The method should also work well with carbon nanotubes, quantum dots, nanowires, etc.
For example, after synthesis, nanoribbons are transferred to SiO2 on Si with a copolymer of crosslinkable PMMA. The copolymer consisting of 96 mol % MMA with 4 mol % of thermally cross-linkable GMA, PMMA-GMA, is spin-coated on the sample, and the films are thermally annealed to promote better bonding of the copolymer with the nanoribbon/Ge substrate. Excess polymer is removed by rinsing in toluene, resulting in a film that is 3 to 5 nm in thickness. Additional PMMA is spin-coated on top of the PMMA-GMA film, and the substrate is annealed in a nitrogen environment. The backside of the sample that is uncoated with polymer undergoes an oxygen plasma etch to remove graphene. The sample is then floated on 3:1:1 H2O:HF:H2O2 to etch the Ge substrate. The nanoribbon/polymer membrane is transferred from the Ge etchant to three successive water baths and finally to a piranha cleaned SiO2 on Si substrate. The substrate is spin dried and then annealed in an N2 environment. The substrate is soaked in acetone and subsequently thermally annealed to remove polymer residue. less

PC-Indexed Data Address Translation (PCAX), assists with conventional data address translation which employs a conventional Data Translation Lookaside Buffer. The approach relies on using the identity of an instruction (the instruction PC), and not on the actual data address, to obtain a page table entry for the data address that is expected to be accessed by the instruction. PCAX is intended to be used for a small subset of load instructions: those whose data translation access is expected to miss in a CDLTB.
The inventors have determined that: (1) a relatively small number of instructions statically identified by their program counter (PC) values are responsible for a disproportionate number of misses in a TLB, and (2) dynamic instances of these instructions frequently access the same page table entry. Accordingly, a relatively small table indexed with the PC value of an instruction, and holding page table entry information (pairs of virtual and physical memory addresses) can be used to provide an address translation for the data that the instruction is accessing, producing an acceleration in translation time and also providing energy savings. less

medical device for transcranial or transdermal magnetic stimulation
(TMS) promising to enhance treatment of neurological disorders. Its
unique coil design permits modulation of magnetic fields to penetrate
deeper brain regions while maintaining focality.
MarketThis innovation addresses the limitations of
current TMS devices. Despite the widespread clinical use of TMS over the
past three decades, the design of TMS devices has seen minimal
modifications, particularly concerning size and adaptability. The
introduction of an adjustable focus magnetic stimulation coil directly
addresses limitations of current technologies by offering a solution
that not only enhances the precision and depth of neural stimulation but
also provides the flexibility required for varied clinical
applications. The global TMS market, estimated at USD 1.13
billion in 2022, is expected to grow at a Compound Annual Growth Rate
(CAGR) of 9.0% to reach USD 2.26 billion by 2030. This growth trajectory
underscores the increasing demand for effective and non-invasive
neurological treatments, propelled by the rising prevalence of
neurological conditions such as Alzheimer's disease, Parkinson's
disease, and depression. The Adjustable Focus Magnetic Stimulation Coil,
with its innovative approach to deep and focused brain stimulation, is
positioned to meet this demand by offering a technology that surpasses
the capabilities of existing TMS devices in both functionality and
clinical outcomes.
TechnologyThe Adjustable Focus Magnetic Stimulation Coil
represents a significant leap forward in the field of medical devices,
particularly in the realm of transcranial or transdermal magnetic
stimulation (TMS). Developed to overcome the inherent limitations of
conventional magnetic stimulators, this patented technology introduces a
novel approach to achieving deeper brain stimulation without
sacrificing precision and focality. The core innovation of this technology lies in its
unique coil design, which employs an adjustable wrapping angle of an
electrically conductive coil around a magnetic core. This design
principle allows for the modulation of the coil's magnetic field,
enabling it to penetrate deeper brain regions while maintaining a
focused effect. Unlike traditional TMS tools, which are constrained by a
depth-spread tradeoff—wherein the magnetic field weakens and spreads as
it penetrates deeper—this invention utilizes symmetry-breaking coil
designs to concentrate the magnetic field and enhance its depth
penetration capabilities. One of the key aspects of this technology is its
ability to adjust the focal spot size of the magnetic stimulation,
offering unparalleled flexibility for various medical applications. By
tilting the coil's wire wrapping angle relative to the magnetic core
direction, the invention breaks the coil's circular symmetry, resulting
in focused stimulations that are more precise and effective. This
feature is particularly beneficial for targeting specific areas within
the brain or body, making it an invaluable tool for treating
neurological and neurodegenerative diseases. The Adjustable Focus Magnetic Stimulation Coil
boasts several advantages over existing solutions. Firstly, its
innovative coil design facilitates better focality and depth
penetration, allowing for targeted stimulation of deeper brain regions.
Additionally, the adjustable focal spot size caters to diverse medical
needs, enabling clinicians to tailor the stimulation to individual
patient requirements. The technology also leverages iron core and
tilted-angle coil designs to produce peak electric fields, further
enhancing its effectiveness.
