Integrating Directed Self Assembly (DSA) and Multiple Patterning (MP) is an attractive option for printing contact and via layers for sub-7nm process nodes. In the DSA-MP hybrid process, an optimized decomposition algorithm is required to perform the MP mask assignment while considering the DSA advantages and limitations. In this paper, we present an(More)
SSTA has received a considerable amount of attention in recent years. However, it is a general rule that any approach can only be as accurate as the underlying models. Thus, variation models are an important research topic, in addition to the development of statistical timing tools. These models attempt to predict fluctuations in parameters like doping(More)
 This study uses a new strategy to investigate the hypothesis that, of the various Ca2+ channels expressed by a neurosecretory cell, a given channel subtype is coupled more tightly to the exocytotic apparatus than others. The approach is based on the prediction that the degree of inhibition of the secretory response by various Ca2+ channel blockers will(More)
One of the UN sustainable development goals is to achieve universal access to safe and affordable drinking water by 2030. It is locations like Kathmandu, Nepal, a densely populated city in South Asia with endemic typhoid fever, where this goal is most pertinent. Aiming to understand the public health implications of water quality in Kathmandu we subjected(More)
Modern CMOS technologies employ process-induced stress to improve carrier mobility and increase drive current. This stress has been shown to be strongly layout dependent; however there is a lack of physical models relating potential performance variation to critical layout parameters. This paper presents compact <i>closed-form</i> models that capture the(More)
Directed self assembly (DSA) is a very promising candidate for the sub-7 nm technology nodes. To print such small dimensions, multiple patterning (MP) is likely to be used to print the guiding templates for DSA. Therefore, algorithms are required to perform the DSA grouping at the same time as the mask assignment. In this paper, we present an optimal(More)
A new trypanosomatid species, Blastocrithidia cyrtomeni, is herein described using morphological and molecular data. It was found parasitising the alimentary tract of the insect host Cyrtomenus bergi, a polyphagous pest. The morphology of B. cyrtomeni was investigated using light and transmission microscopy and molecular phylogeny was inferred from the(More)
