18 Jun 2018TL;DR: This work demonstrates how to fuse two detectors into a tracking system using the Frank-Wolfe algorithm, and proposes to formulate tracking as a weighted graph labeling problem, resulting in a binary quadratic program.
Abstract: In order to track all persons in a scene, the tracking-by-detection paradigm has proven to be a very effective approach. Yet, relying solely on a single detector is also a major limitation, as useful image information might be ignored. Consequently, this work demonstrates how to fuse two detectors into a tracking system. To obtain the trajectories, we propose to formulate tracking as a weighted graph labeling problem, resulting in a binary quadratic program. As such problems are NP-hard, the solution can only be approximated. Based on the Frank-Wolfe algorithm, we present a new solver that is crucial to handle such difficult problems. Evaluation on pedestrian tracking is provided for multiple scenarios, showing superior results over single detector tracking and standard QP-solvers. Finally, our tracker ranks 2nd on the MOT16 benchmark and 1st on the new MOT17 benchmark, outperforming over 90 trackers.

TL;DR: This work reports the combination of oppositely charged Ti 3 C 2 T x MXene membranes (MXMs) with confined 2D nanofluidic channels as high-performance osmotic power generators, making this blue energy a tangible and promising alternative.
Abstract: Membrane-based reverse electrodialysis (RED) is considered as the most promising technique to harvest osmotic energy. However, the traditional membranes are limited by high internal resistance and low efficiency, resulting in undesirable power densities. Herein, we report the combination of oppositely charged Ti3 C2 Tx MXene membranes (MXMs) with confined 2D nanofluidic channels as high-performance osmotic power generators. The negatively or positively charged 2D MXene nanochannels exhibit typical surface-charge-governed ion transport and show excellent cation or anion selectivity. By mixing the artificial sea water (0.5 m NaCl) and river water (0.01 m NaCl), we obtain a maximum power density of ca. 4.6 Wm-2 , higher than most of the state-of-the-art membrane-based osmotic power generators, and very close to the commercialization benchmark (5 Wm-2 ). Through connecting ten tandem MXM-RED stacks, the output voltage can reach up 1.66 V, which can directly power the electronic devices.

TL;DR: In this article, a method for the determination of concentration gradients in the vicinity of plant roots is described, in which plants are grown in small containers in which the roots are separated from the soil by a screen of nylon cloth.
Abstract: A method is described for the determination of concentration gradients in the vicinity of plant roots. Plants are grown in small containers in which the roots are separated from the soil by a screen of nylon cloth. Root hairs but not roots penetrate the screen into the soil. In order to investigate the rhizospheric soil, the soil is frozen by liquid nitrogen and sliced into layers about 0.06 mm thick by means of a refrigerated microtome.

TL;DR: In this paper, the authors presented upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO 600 gravitational wave detectors.
Abstract: We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO 600 gravitational wave detectors The data from both runs have been combined coherently to maximize sensitivity For the first time, pulsars within binary (or multiple) systems have been included in the search by taking into account the signal modulation due to their orbits Our upper limits are therefore the first measured for 56 of these pulsars For the remaining 22, our results improve on previous upper limits by up to a factor of 10 For example, our tightest upper limit on the gravitational strain is 26×10-25 for PSR J1603-7202, and the equatorial ellipticity of PSR J2124–3358 is less than 10-6 Furthermore, our strain upper limit for the Crab pulsar is only 22 times greater than the fiducial spin-down limit
