New PCM based FPGA architecture and graphene memory cell design
In this work, we introduce a new look-up table (LUT) implementation using phase change memory (PCM) cells. Utilizing the fact that PCM cells store data using resistance values, unlike traditional memory cells, the memory cell we propose can store up to 2 bits per cell. This is achieved by …

Improved Designs for Application Virtualization
We propose solutions for application virtualization to mitigate the performance loss in streaming and browser-based applications. For the application streaming, we propose a solution which keeps operating system components and application software at the server and streams them to the client side …

Investigation of glucose and energy metabolism in eumenorrheic female ultra-runners across the menstrual cycle
… provided, in the mid-follicular (FOL) and mid-luteal phases (LUT). Using a mixed linear model, the menstrual phase was identified as being statistically significant for differences in glucose measurements between CGM and capillary glucose during TREAD (p = 0.02) but not FASTED. Also, the CGM …

Synthesis and reactivity of high oxidation state tungsten and molybdenum olefin metathesis catalysts bearing new imido ligands
… Addition of one equivalent of 2,6-lutidinium chloride, followed by alkylation affords dialkyl species M(NHIPT)(N'Bu)Np 2, and treatment with three equivalents of pyridinium chloride yields all anti imidoalkylidene dichloride species as mono-pyridine adducts, M(NHIPT)(CHCMe 3)C 2(py) …

Fault tolerant, low voltage SRAM design
… Meanwhile, compared to the look-up table (LUT) decoder, the decision-tree based architecture has 2X area and power savings. Hence, the tree-based decoder is an alternative design which does not have the extreme power and area consumption of a LUT decoder and does not have the extreme …

Control System for Outdoor Use of Powered Portable Ankle-Foot Orthosis
… by comparing the output of a Look-Up Table (LUT) against gait variations in simulated subjects. The results show that while a general LUT offers some compatibility, performance significantly improves with condition-specific LUTs that incorporate factors like terrain inclination. A sensitivity …
