Combining gradient ascent search and support vector machines for effective autofocus of a field emission–scanning electron microscope
Summary Autofocus is an important issue in electron microscopy, particularly at high magnification. It consists in searching for sharp image of a specimen, that is corresponding to the peak of focus. The paper presents a machine learning solution to this issue. From seven focus measures, support vector machines fitting is used to compute the peak with an initial guess obtained from a gradient ascent search, that is search in the direction of higher gradient of focus. The solution is implemented on a Carl Zeiss Auriga FE‐SEM with a three benchmark specimen and magnification ranging from x300 to x160 000. Based on regulari...

Use of an informed search space maximizes confidence of site-specific assignment of glycoprotein glycosylation.
Abstract In order to interpret glycopeptide tandem mass spectra, it is necessary to estimate the theoretical glycan compositions and peptide sequences, known as the search space. The simplest way to do this is to build a naïve search space from sets of glycan compositions from public databases and to assume that the target glycoprotein is pure. Often, however, purified glycoproteins contain co-purified glycoprotein contaminants that have the potential to confound assignment of tandem mass spectra based on naïve assumptions. In addition, there is increasing need to characterize glycopeptides from complex biologic...

An Individual Differences Approach to Multiple-Target Visual Search Errors: How Search Errors Relate to Different Characteristics of Attention.
Abstract Multiple-target visual searches, where more than one target can be present within a single search array, are especially error-prone such that a second target is more likely to be missed after a first target has been detected. Increasingly, evidence supports a resource depletion account of these errors-a first target consumes attentional resources leaving fewer available to process a second target. However, "attention" is broadly defined and is composed of many different characteristics, leaving considerable uncertainty about how attention affects second-target detection. The goal of the current study was ...

Sensors, Vol. 18, Pages 2535: A Probabilistic Target Search Algorithm Based on Hierarchical Collaboration for Improving Rapidity of Drones
a Finding a target quickly is one of the most important tasks in drone operations. In particular, rapid target detection is a critical issue for tasks such as finding rescue victims during the golden period, environmental monitoring, locating military facilities, and monitoring natural disasters. Therefore, in this study, an improved hierarchical probabilistic target search algorithm based on the collaboration of drones at different altitudes is proposed. This is a method for reducing the search time and search distance by improving the information transfer methods between high-altitude and low-altitude drones. Specifi...

Is Movember synonymous with moustaches or men's health? An examination of internet search activity for prostate and testicular cancer during the campaign
ConclusionWe concluded that the Movember campaign is consistently linked in the public consciousness with novelty facial hair and only weakly associated with an awareness of prostate and testicular cancers. Whilst the funding generated by the campaign should be commended, more could be done to link the campaign and moustaches to awareness of common male cancers.

Characterizing internet search patterns for neurologic and neurosurgical conditions following celebrity diagnosis
CONCLUSIONS: Following major events related to the neurological disease of public figures there is an expected rise in Google search interest relevant to these topics. Our findings suggest that there is an optimal window of approximately 2 weeks following each of these events for activist and clinical groups to publicize their desired message, and for the field of neurosurgery and neurological science to increase public awareness regarding specific diseases, with a regression to baseline interest by 4-months following the event.PMID:34763394 | DOI:10.23736/S0390-5616.21.05569-7
