Med Image Anal 2021 Jun 7;72:102126. Epub 2021 Jun 7.

Videos & Images Theory and Analytics Laboratory (VITAL), Department of Computer Science, Université de Sherbrooke, 2500, boul. de l'Université, Sherbrooke, Québec J1K 2R1, Canada.

Current brain white matter fiber tracking techniques show a number of problems, including: generating large proportions of streamlines that do not accurately describe the underlying anatomy; extracting streamlines that are not supported by the underlying diffusion signal; and under-representing some fiber populations, among others. In this paper, we describe a novel autoencoder-based learning method to filter streamlines from diffusion MRI tractography, and hence, to obtain more reliable tractograms. Our method, dubbed FINTA (Filtering in Tractography using Autoencoders) uses raw, unlabeled tractograms to train the autoencoder, and to learn a robust representation of brain streamlines. Read More

Department of Animal Sciences, The Hebrew University of Jerusalem, Robert H. Smith Faculty of Agriculture, Food and Environment, Rehovot 76100, Israel.

Targeted in ovo green light (GL) photostimulation during the last days of broiler egg incubation increases embryonic expression of the somatotropic axis, similar to in ovo green light photostimulation from embryonic day (ED) 0 to the end of incubation. The aim of this study was to examine the effect of selected in ovo GL photostimulation periods on post-hatch broiler growth. Four hundred twenty fertile broiler eggs were divided into 7 treatment groups: the first incubated in the dark (standard conditions) as a negative control; the second incubated under monochromatic GL from ED0-ED20 (positive control); the third group incubated under monochromatic GL light from ED15-ED20; the fourth, fifth and sixth groups were incubated under monochromatic GL on ED16, ED17, and ED18, respectively; and the seventh group was incubated under monochromatic GL from ED18-ED20.

Exploring the distribution of statistical feature parameters for natural sound textures.

PLoS One 2021 23;16(6):e0238960. Epub 2021 Jun 23.

Dept. of Neuroscience, City University of Hong Kong, Hong Kong, Hong Kong.

Sounds like "running water" and "buzzing bees" are classes of sounds which are a collective result of many similar acoustic events and are known as "sound textures". A recent psychoacoustic study using sound textures has reported that natural sounding textures can be synthesized from white noise by imposing statistical features such as marginals and correlations computed from the outputs of cochlear models responding to the textures. The outputs being the envelopes of bandpass filter responses, the 'cochlear envelope'. Read More

Inter-Patient Atrial Flutter Classification Using FFT-Based Features and a Low-Variance Stacking Classifier.

IEEE Trans Biomed Eng 2021 Jun 23;PP. Epub 2021 Jun 23.

Objective: Atrial Flutter (AFL) is a supraventricular tachyarrhythmia typically arising from a macroreentry circuit that can have variable atrial anatomy. It is often treated by catheter ablation, the success of which depends upon the correct determination of the electroanatomic circuit, generally through invasive electrophysiological (EP) study. We hypothesized that machine learning (ML) methods applied to the diagnostic 12-lead surface electrocardiogram (ECG) could determine the specific circuit prior to any invasive EP study. Read More

Digest: Taxonomically Inclusive and Quantitative Tests for Convergence.

Authors:
Laura E Hunter

Evolution 2021 Jun 23. Epub 2021 Jun 23.

Department of Organismal Biology and Anatomy, University of Chicago.

How common is morphological convergence, and can the cause of convergence be traced to simple ecological categories like diet? Tamagnini et al. (2021) use phylogenetic comparative methods and simple morphological data from a large number of Carnivora taxa to investigate whether diet causes convergence in their craniomandibular complex. They find that convergence is less prevalent than expected and that this outcome is likely caused by a complex interplay between biomechanics, ecology, and morphology. Read More
