In plants, the developmental mechanisms that regulate the positioning of lateral organs along the primary root are currently unknown. We present evidence on how lateral root initiation is controlled in a spatiotemporal manner in the model plant Arabidopsis thaliana. First, lateral roots are spaced along the main axis in a regular left-right alternating pattern that correlates with gravity-induc...

Channel state information (CSI)-based fingerprinting via neural networks (NNs) is a promising approach to enable accurate indoor and outdoor positioning of user equipment (UE), even under challenging propagation conditions. In this paper, we propose pipeline for wireless LAN MIMO-OFDM systems which uses uplink CSI measurements obtained from one or more unsynchronized access points (APs). For ea...

Malformed or congenitally missing teeth are a problem often faced by both orthodontists and restorative dentists. Between 1% and 2% of the population will exhibit a shape modification of the maxillary lateral incisor commonly referred to as a peg lateral. The inheritance of the peg-shaped lateral incisors has been associated with the genotype that causes missing lateral incisors, and the shape ...

Image Acquisition Ultrasonography of the larynx can be performed using standard ultrasound equipment suitable for musculoskeletal examinations. A 7-10 megahertz linear or microconvex transducer provides good resolution and adequate penetration. Sedation is often necessary, as it facilitates patient cooperation and relaxation to allow extension of the head permitting access to the laryngeal regi...

With the constant platform fragmentation in the global smartphone and tablet market, providing a multiplatform indoor positioning technology is and ever more complex task. RSSI-based hybrid indoor positioning technologies provide hope for a unified indoor positioning solution with-out the need for calibrating each and every device manually before use. But differing antenna construction, sensor ...

In this paper we are proposing an approach for flexible positioning of players in Soccer Simulation in a Multi-Agent environment. We introduce Dynamic Positioning based on Voronoi Cells (DPVC) as a new method for players’ positioning which uses Voronoi Diagram for distributing agents in the field. This method also uses Attraction Vectors that indicate agents’ tendency to specific objects in the...

Aiming at the problem that position errors accumulate rapidly in foot-mounted pedestrian navigation systems using a low-cost inertial sensor, novel three-dimensional (3D) positioning method is proposed. First, when foot still, an improved zero velocity detection assigns different weights to each measurement unit (IMU) data sliding window designed reduce errors. When swing, lateral restriction p...

Ordering phenomena related to the self-assembly of InAs quantum dots (QD) grown on GaAs(001) substrates are experimentally investigated on different length scales. On the shortest length-scale studied here, we examine the QD morphology and observe two types of QD shapes, i.e., pyramids and domes. Pyramids are elongated along the [1–10] directions and are bounded by {137} facets, while domes hav...

PURPOSE The purpose of this noninvasive pilot study was to examine the changes in transcutaneous oxygen (tcO2), skin temperature, and hyperemic response in the heels, sacrum, and trochanters in a 2-hour loading-unloading condition in nursing home residents who are positioned in supine and lateral positions. DESIGN A 1-group, prospective, repeated-measures design was used. SUBJECTS AND SETTI...

The satellite navigation signal in the tunnel is weak, and it difficult to achieve accurate lateral positioning complex conditions such as low-speed congestion by relying solely on inertial or line image recognition, which one of problems automatic driving at present. In this paper, a lane-level location method based multi-sensor fusion proposed. Using machine vision method, detecting lane line...
