Journal of Research of the National Institute of Standards and Technology, 2014 A digraph whose degree sequence has a unique vertex labeled realization is called threshold. In this paper we present several characterizations of threshold digraphs and their degree sequences, and show these characterizations to be equivalent. One of the characterizations is new, and allows for a shorter proof of the equivalence of the two known ...

Shell rupture threshold, fragmentation threshold, blake threshold [PDF]
IEEE Ultrasonics Symposium, 2005., 2006 The disruption of contrast agent microbubbles has been implicated in novel techniques for high-MI imaging and local drug delivery. At MI>0.6, microbubble fragmentation has been observed with thin-shelled agent (≈10 nm), and shell rupture with thick-shelled agent (≈250 nm).

MANAS: Journal of Engineering, 2023 Multiple choice exams appear as the most common method used to measure student success in education systems in Turkey and around the world. Evaluation of multiple choice exams is usually done by optical form reading systems using expensive optical forms ...

Journal of Marine Science and Engineering, 2023 Satellite image analysis is a potentially powerful tool for monitoring coastal shoreline positions. This study explores the use of multi-temporal, dual-polarised Sentinel-1 GRD synthetic aperture radar (SAR) imagery with a spatial resolution of 10 m for ...

Frontiers in Human Neuroscience, 2023 IntroductionBrain tumors arise due to abnormal growth of cells at any brain location with uneven boundaries and shapes. Usually, they proliferate rapidly, and their size increases by approximately 1.4% a day, resulting in invisible illness and ...

The reinfection threshold [PDF]
Journal of Theoretical Biology, 2005 Thresholds in transmission are responsible for critical changes in infectious disease epidemiology. The epidemic threshold indicates whether infection invades a totally susceptible population. The reinfection threshold indicates whether self-sustained transmission occurs in a population that has developed a degree of partial immunity to the pathogen ...

IEEE Access, 2021 Suspicious region segmentation is one of the most important parts of CAD systems that are used for breast cancer detection in mammograms. In a CAD system, there can be so many suspicious regions determined for a mammogram because of the complex structure

To threshold or not to threshold? That's the question [PDF]
Ecological Indicators, 2012 Abstract The concept of evaluating multiple alternative models to determine ecological response form is over a century old and is ever more relevant as modern computing power allows ever more complicated models to be routinely used but often without a reasonable model verification process, particularly in fields where the ecological conceptual model ...

Thresholds versus fractional expectation-thresholds [PDF]
Annals of Mathematics, 2021 Proving a conjecture of Talagrand, a fractional version of the 'expectation-threshold' conjecture of Kalai and the second author, we show for any increasing family $F$ on a finite set $X$ that $p_c (F) =O( q_f (F) \log \ell(F))$, where $p_c(F)$ and $q_f(F)$ are the threshold and 'fractional expectation-threshold' of $F$, and $\ell(F)$ is the largest ...
