An OCT method to improve scleral lens fitting
Summary The current technology allows for accurate and objective 3-dimensional (3D) mapping of the external limbus, which could ultimately improve the process of scleral lens fitting. Technology Overview Rigid scleral lenses are difficult to fit to patients because they must rest on the eye but vault over the cornea and the limbus, which is the transition...

High-Throughput Direct-Measurement of Telomere Length
Telomeres are linear chromosome end-capping repetitive DNA sequences. They serve to protect the ends of chromosomes from undesirable fusion events, thus integrity and length are crucial for stability. Natural attrition as well as mutations can affect telomere integrity and length resulting in chromosome instability, senescence, cell death and human...

Masked-Based Learning Method for Neural Network Multiple Task Adaption
Nowadays, one practical limitation of deep neural networks (DNNs) is their high degree of specialization to a single task. This motivates researchers to develop algorithms that can adapt the DNN model to multiple tasks sequentially, while still performing well on past tasks. This process of gradually adapting the DNN model to learn from different...

Memory Efficient, Multi-Domain On-Device Machine Learning
­One practical limitation of deep neural network (DNN) is its high degree of specialization to a single task or domain (e.g., one visual domain). This motivates the development of algorithms that can adapt DNN model to multiple domains sequentially while still performing well on past domains. This is known as multi-domain learning. Conventional...

Binary Neural Network for Improved Accuracy and Defense Against Bit-Flip Attacks
­Recently, Deep Neural Networks (DNNs) have been deployed in many safety-critical applications. The security of DNN models can be compromised by adversarial input examples, where the adversary maliciously crafts and adds input noise to fool a DNN model. The perturbation of model parameters (e.g., weight) is another security concern, one that relates...
