A cooperative scheme for late leaf spot estimation in peanut using UAV multispectral images.

In Australia, peanuts are mainly grown in Queensland with tropical and subtropical climates. The most common foliar disease that poses a severe threat to quality peanut production is late leaf spot (LLS). Unmanned aerial vehicles (UAVs) have been widely investigated for various plant trait estimations.

Evaluation of linkage disequilibrium, population structure, and genetic diversity in the U.S. peanut mini core collection.

Background: Due to the recent domestication of peanut from a single tetraploidization event, relatively little genetic diversity underlies the extensive morphological and agronomic diversity in peanut cultivars today. To broaden the genetic variation in future breeding programs, it is necessary to characterize germplasm accessions for new sources of variation and to leverage the power of genome-wide association studies (GWAS) to discover markers associated with traits of interest. We report an analysis of linkage disequilibrium (LD), population structure, and genetic diversity, and examine the ability of GWA to infer marker-trait associations in the U.

The apomediated world: regulating research when social media has changed research.

Social Media, like Facebook and Twitter, are having a profound effect on the way that human subjects research is being conducted. In light of the changes proposed in ANPRM, in this article I argue that traditional research ethics and regulations may not easily translate to the use of social media in human subjects research. Using the conceptual model of apomediation, which describes the peer-to-peer way in which health information is shared via social media, I suggest that we may need to think again about the suitability of current regulations to deal with social media research.

Activity in motor-sensory projections reveals distributed coding in somatosensation.

Cortical-feedback projections to primary sensory areas terminate most heavily in layer 1 (L1) of the neocortex, where they make synapses with tuft dendrites of pyramidal neurons. L1 input is thought to provide ‘contextual’ information, but the signals transmitted by L1 feedback remain uncharacterized. In the rodent somatosensory system, the spatially diffuse feedback projection from vibrissal motor cortex (vM1) to vibrissal somatosensory cortex (vS1, also known as the barrel cortex) may allow whisker touch to be interpreted in the context of whisker position to compute object location.

Immediate, full weightbearing cast treatment of acute Achilles tendon ruptures: a long-term follow-up study.

Thirty-two patients with 33 ruptures were available for comprehensive evaluation, which included a questionnaire, physical examination, and manual as well as objective (Kin-Com) strength testing. Data excluding Kin-Com strength testing were available in an additional seven patients with seven ruptures; hence, the data are based on these 39 patients with 40 ruptures. Five patients with eight ruptures were excluded from strength testing but were included in our rerupture data, which totaled 44 patients with 48 ruptures.
