Application telemetry refers to measurements taken from software systems assess their performance, availability, correctness, efficiency, and other aspects useful operators, as well troubleshoot them when they behave abnormally. Many modern observability platforms support dimensional models of signals where the are accompanied by additional dimensions used identify either resources described or...

Genetic mapping is one of the key steps in positional cloning. The traditional mapping strategies typically require to genotype a set of markers that are nearly evenly or randomly distributed across the genome or a region of interest. Such "grid" strategies work with low efficiency. We propose an improved mapping strategy by integrating the principle of one-dimensional optimization and informat...

background: benign paroxysmal positional vertigo (bppv) is linked to vitamin d deficiency. this clinical trial aimed to determine the influence of vitamin d supplementation on intensity of bppv. methods: the study population was selected consecutively and the diagnosis of bppv was made by history and clinical examination and exclusion of other conditions. intensity of bpvv was assessed based on...

Phylogenetic analyses of non-protein-coding nucleotide sequences such as ribosomal RNA genes, internal transcribed spacers, and introns are often impeded by regions of the alignments that are ambiguously aligned. These regions are characterized by the presence of gaps and their uncertain positions, no matter which optimization criteria are used. This problem is particularly acute in large-scale...

To fulfill adequately their functions of support, sustentation and protection for the internal organs and guarantee blood calcium homeostasis, bone tissue is in constant remodeling. Alveolar bone, the primary support structure for teeth, is particularly subjected to continuous and fast remodeling associated with tooth eruption and positional adaptations, as well as with the functional demands o...

Urodele amphibians are unique among adult vertebrates in their ability to regenerate complex body structures after traumatic injury. In salamander regeneration, the cells maintain a memory of their original position and use this positional information to recreate the missing pattern. We used an in vivo gain-of-function assay to determine whether components of the extracellular matrix (ECM) have...

We describe a novel, inexpensive method for real-time measurement of binocular three-dimensional eye position. The method employs consumer-grade digital video cameras ("webcams") to track an array of three fluorescent non-collinear markers affixed to each eye. The instantaneous position of the marker array relative to a reference position is used to construct a rotation matrix describing the ey...

Responses of parafoveal macaque ganglion cells were measured as a function of the contrast and position of an edge flashed within their receptive fields. The goal was to determine the ability of different cell types to signal edge location. For comparison, parafoveal vernier thresholds of human observers were measured with pairs of flashed edges. Cells of the magnocellular (MC-) pathway gave la...

Fibroblasts are ubiquitous mesenchymal cells with many vital functions during development, tissue repair, and disease. Fibroblasts from different anatomic sites have distinct and characteristic gene expression patterns, but the principles that govern their molecular specialization are poorly understood. Spatial organization of cellular differentiation may be achieved by unique specification of ...
