Nanomaterials and Cross-Cutting Technologies
The electrochemical biosensor is defined as a chemical sensor constituted of a recognition element and an electrochemical transducer, in which the device is able to transform the biochemical information related to the interaction of the analyte with the recognition element into an electrochemically detectable signal.

Time Series Analysis
With the advent of the digital computer, time series analysis has gained wide attention and is being applied to many fields of science. In this survey entry, many traditional and recent techniques for time series analysis and change detection are reviewed, including spectral and wavelet analyses with their advantages and weaknesses. The main focus of the survey is the analysis of unevenly sampled or unequally spaced time series.

Architecture of OkeyDoggy3D
The 2D pose is estimated from the multi-view RGB videos using the DeepLabCut model. Subsequently, the dog joint position-based dataset is prepared based on a camera calibration and triangulation using the Anipose algorithm by predicting the 3D pose from the 2D pose of the dog in a multi-view RGB video extracted using the DeepLabCut model.

Electrically Tunable Phase Gratings
Electrically tunable phase gratings are able to steer an incoming light beam without employing movable parts. Here, we present the design and implementation of a 2D beam steering device by cascading two orthogonal 1D liquid crystal (LC) based phase gratings, each having an array of 72 rectangular individually controlled pixels and driven by a custom 12-bit Pulse-Width Modulation (PWM) electrical driver.

Spiral Ground Heat Exchanger
Spiral ground heat exchangers in heat pump applications play an important role in heating/cooling of buildings. Energy consumption of buildings is a significant factor in global environmental issues. One of the ways of supplying heating and cooling is using potential energy stored in the ground which is clean and sustainable. These types of systems are called ground source heat pump (GSHP) systems. The initial cost and efficiency of GSHP systems can be influenced by optimal design of ground heat exchangers (GHEs). Many parameters influencing thermal performance of spiral GHEs such as external major diameter of borehole, spacing, distance between each turns of spiral GHEs, etc. When we have a large application area, one spiral GHE is not enough for supplying heating or cooling demands of the building. In this case more than one GHE is needed to be embedded into the ground. When we have more than one GHE in ground, optimization of distance between them becomes an essential problem. Another important parameter which is highly affecting thermal performance of a GSHP system are thermal properties of ground. Before integrating a GSHP system to the building thermal properties of ground or soil should be determined.

Mk F3 155mm
The 155 mm self-propelled gun Mk F3, or the Canon de 155 mm Mle F3 Automoteur (Cn-155-F3-Am), was developed in the early 1950s by the French Army to replace their American M41 Gorilla 155mm self-propelled guns. The Mk F3 is the smallest and lightest 155 mm motorized gun carriage ever produced, and because of its size and low cost it has found considerable success on the export market. Constructed on a modified AMX-13 light tank chassis, the Mk F3 is novel in incorporating room inside for only two of the eight required crewmen (the others riding in support vehicles). This allows the 155 mm gun to be placed on a smaller chassis than that employed by other armies, but exposes the outside crew members to enemy fire and other hazards.

Kounotori 2
Kounotori 2 (こうのとり2号機, "white stork" ), also known as HTV-2, was launched in January 2011 and was the second Japan ese H-II Transfer Vehicle to resupply the International Space Station (ISS). It was launched by the H-IIB Launch Vehicle No. 2 (H-IIB F2) manufactured by Mitsubishi Heavy Industries (MHI) and JAXA. After the supplies were unloaded, Kounotori 2 was loaded with waste material from ISS, including used experiment equipment and used clothes. Kounotori 2 was then unberthed and separated from the ISS and burned up upon reentering the atmosphere on 30 March 2011.
