Adaptive Network Stabilization Despite Profound Structural Reorganization in Human Organotypic Cultures

Advanced Science, EarlyView.
Adult human organotypic cortical slices undergo marked neuronal loss, laminar disruption, and glial activation, yet their network activity progressively stabilizes after a variable period. Electrophysiology, longitudinal calcium imaging, and quantitative histology show that structurally remodeled human circuits show adaptive capacity resulting in ...

Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

Advanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

Teaching Digital Noise and Noise Margin Issues in Engineering Education

IEEE Transactions on Education, 2005
This work presents digital noise in signal integrity and clarifies noise margin issues in digital electronics education. For the static noise margin, the traditional definition violates the basic principle of noise. The embedded rectangle method to define the static noise margin is a more reliable criterion.

A Comparative Study of Margin Noise Removal Algorithms on MarNR: A Margin Noise Dataset of Document Images

2017 14th IAPR International Conference on Document Analysis and Recognition (ICDAR), 2017
Margin noise removal is an important step prior to segmentation and optical character recognition (OCR) of a page. Presence of this noise results in erroneous output by the segmentation algorithms and OCR systems. In this paper, we present a margin noise removal dataset MarNR.

Dynamic Noise Margin: Definitions and Model

17th International Conference on VLSI Design. Proceedings., 2004
Dynamic noise analysis is greatly needed in place of traditional static noise analysis due to the ever increasingly stringent design requirement for VLSI chips based on very deep submicron process technology. In this paper, we propose complete and self-consistent dynamic noise margin definitions to reduce the pessimism of conventional static noise ...

Modeling and Analysis of Noise Margin in SET Logic

20th International Conference on VLSI Design held jointly with 6th International Conference on Embedded Systems (VLSID'07), 2007
In this paper the static noise margin for SET (single electron transistor) logic is defined and compact models for the noise margin are developed by making use of the MIB (Mahapatra-Ionescu-Banerjee) model. The variation of the noise margin with temperature and background charge is also studied.

Transient Noise Failures in SRAM Cells: Dynamic Noise Margin Metric

2011 Asian Test Symposium, 2011
Current nanometric IC processes need to assess the robustness of memories under any possible source of disturbance: process and mismatch variations, bulk noises, supply rings variations, temperature changes, aging and environmental aggressions such as RF or on-chip couplings.

Noise Margin Criteria for Digital Logic Circuits

IEEE Transactions on Education, 1993
Techniques for evaluating the noise margin for families of digital logic circuits are discussed and evaluated. It is shown that the technique of evaluating the -1 slope points on the inverter transfer function as used in most modern textbooks is not a valid and reliable approach to evaluating noise margin values. It is argued that the most reliable and

Static and Dynamic Noise Margins of Logic Circuits

IEEE Journal of Solid-State Circuits, 1979
Explaining four basic types of noise, and by showing the various methods, together with boundary conditions, which can be used to find the worst case noise margins. A flip-flop setup is advised which can be used for measurements and computer simulations, both for static and dynamic noise margins.

Noise-Margin Analysis for Organic Thin-Film Complementary Technology

IEEE Transactions on Electron Devices, 2010
Parameter variation in organic thin-film transistor (OTFT) technology is known to limit the yield of digital circuits. It is expected that complementary OTFT technology (C-TFT) will reduce the sensitivity to parameter variations.
