ToRPEDO Privacy Attack on 4G/5G Networks Affects All U.S. Carriers

Posted by in categories: energy, internet, military

The attack threatens users with location-tracking, DoS, fake notifications and more.

Privacy-breaking flaws in the 4G and 5G mobile protocols could allow attackers to intercept calls, send fake amber alerts or other notifications, track location and more, according to a research team from Purdue University and the University of Iowa.

In a paper presented at Mobile World Congress in Barcelona this week, the researchers explained that the issues arise from weaknesses in the cellular paging (broadcast) protocol. They started with the fact that when a mobile device is in its idle, low-power state, it will conserve battery life partly by polling for pending services only periodically.

UCF Researchers Develop First Supersymmetric Laser Array

Posted by in category: biotech/medical

A team of University of Central Florida researchers has overcome a long-standing problem in laser science, and the findings could have applications in surgery, drilling and 3D laser mapping.

Using the principle of supersymmetry, they have developed the first supersymmetric laser array. Their findings were published recently in the journal Science.

Supersymmetry is a conjecture in physics that says every particle of matter, such as an electron, has one or more superpartners that is the same except for a precise difference in their momentum.

NVIDIA Transfer Learning Toolkit

Posted by in categories: biotech/medical, robotics/AI

The is ideal for deep learning application developers and data scientists seeking a faster and efficient deep learning training workflow for various industry verticals such as Intelligent Video Analytics (IVA) and Medical Imaging. Transfer Learning Toolkit abstracts and accelerates deep learning training by allowing developers to fine-tune NVIDIA provided pre-trained models that are domain specific instead of going through the time-consuming process of building Deep Neural Networks (DNNs) from scratch. The pre-trained models accelerate the developer’s deep learning training process and eliminate higher costs associated with large scale data collection, labeling, and training models from scratch.

The term “transfer learning” implies that you can extract learned features from an existing neural network and transfer these learned features by transferring weights from an existing neural network. The Transfer Learning Toolkit is a Python based toolkit that enables developers to take advantage of NVIDIA’s pre-trained models and offers technical capabilities for developers to add their own data to make the neural networks smarter by retraining and allowing them to adapt to the new network changes. The capabilities to simply add, prune and retrain networks improves the efficiency and accuracy for deep learning training workflow.

Meet the ‘preeminent AI company on earth,’ but can it succeed in healthcare?

Posted by in categories: entertainment, robotics/AI

Last year, my brother, then an employee at Silicon Valley-based tech company Nvidia, declared that all the AI and deep learning that is happening in healthcare is being powered by Nvidia’s graphics processing units (GPUs)…however that’s just the tip of the iceberg.

Nvidia holds a dominant position in terms of making the chips that power artificial intelligence projects, but can the Silicon Valley tech company with roots in the world of gaming and graphics succeed in healthcare?

Korea: Researchers 3D Printing Tracheas with Epithelial Cells & Chondrocytes

Posted by in categories: 3D printing, bioprinting, biotech/medical

Korean researchers have been experimenting further in the bioprinting of tracheal implants, publishing recent results in ‘Trachea with Autologous Epithelial Cells and Chondrocytes.’ The team of scientists details their use of polycaprolactone and hydrogel mixed with nasal epithelial and auricular cartilage cells.

After bioprinting an artificial trachea with these materials and tissue, they transplanted them into 15 rabbits, six of which were a control group. The goal was to find a way to overcome tracheal problems due to tumors, the most common of which are adenoid cystic carcinomas and squamous cell carcinomas. Previously there have been substantial challenges in creating viable tracheas that are anatomically correct and can produce a ciliated epithelium. Issues have arisen with infection, implants that become dislodged, have migrated, or experienced obstruction.

New milestones in helping prevent eye disease with Verily

Posted by in categories: biotech/medical, information science, robotics/AI

Over the last three years, Google and Verily—Alphabet’s life sciences and healthcare arm—have developed a machine learning algorithm to make it easier to screen for disease, as well as expand access to screening for DR and DME. As part of this effort, we’ve conducted a global clinical research program with a focus on India. Today, we’re sharing that the first real world clinical use of the algorithm is underway at the Aravind Eye Hospital in Madurai, India.

Google and Verily share updates to their initiative to diagnose diabetic eye disease leveraging machine learning.

Open-source software tracks neural activity in real time

Posted by in category: robotics/AI

“A software tool called CaImAn automates the arduous process of tracking the location and activity of neurons. It accomplishes this task using a combination of standard computational methods and machine-learning techniques. In a new paper, the software’s creators demonstrate that CaImAn achieves near-human accuracy in detecting the locations of active neurons based on calcium imaging data.”
