John B. Aird (ship). John B. Aird was a self-discharging lake freighter/bulk carrier that was launched in 1983 and served on the Great Lakes and Saint Lawrence Seaway until 2017. The vessel was owned and operated by Algoma Central during that time, which had named the vessel for a former chairman of the Algoma Central Railway. Prior to the construction of  in 2013, John B. Aird was the last vessel built for the company.

Description
John B. Aird was  long overall and  between perpendiculars with a beam of . The vessel had a gross tonnage (GT) of 22,881 and a deadweight tonnage of 30,958. The ship was powered by two diesel engines driving one shaft with a controllable pitch propeller, rated at . This gave John B. Aird a maximum speed of . The ship was built to seawaymax proportions and had a  depth of . The ship was equipped with a  deck-mounted boom for unloading its cargo.

Service history
Algoma Central ordered the ship to be constructed at Collingwood Shipbuilding in Collingwood, Ontario, with the yard number 224. The fore part of the ship was built at Port Arthur Shipbuilding in Port Arthur, Ontario. The stern section was launched at Collingwood on 21 October 1982 and towed to Port Arthur. The two parts were joined at Port Arthur and the vessel was launched on 18 December 1982. The ship was named for the then lieutenant governor of Ontario John Black Aird, who was a former chairman of the board of Algoma Central Railway. The bulk carrier was completed in June 1983 and christened by the wife of the lieutenant governor in a private ceremony, after an incident aboard the ship prior to a public ceremony on 3 June 1983. Prior to the construction of  in 2013, John B. Aird was the last vessel constructed for Algoma Central during an era of expansion by company. The vessel was registered in Sault Ste. Marie, Ontario.

On 31 May 1985, John B. Aird lost power in the Saint Lawrence Seaway and was forced to tie up at the Snell Lock. The vessel often carried coal and suffered $500,000 damage from a coal fire in her self-unloading machinery on 16 October 1990 while at Indiana Harbor, Indiana. The vessel was taken to Sarnia, Ontario, for repairs. The vessel returned to service in November 1990. The vessel was sold for scrap in 2017 and the vessel's name shortened to John B. and re-registered to Freetown, Sierra Leone. The ship arrived at Aliağa, Turkey to be broken up in May and destruction was finished on 14 June 2017.

Lenticular fabric. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.

In geology
Lenticular fabrics are found in nature.  Geological forces can produce lenticular fabrics consisting of quartz "microlenses" in clay deposits.

In biology
Lenticular fabrics can be created through biological processes.  For example, termites create these fabrics by combining sand with fibrous faeces to create plastic-like translucent barriers.

Technology
Manufactured lenticular fabric is used to make movie projection screens, so that the image will appear sharper and brighter.

Lenticular fabric is often used for decorative purposes.  It is typically made from PVC with an interlaced lenticular image covered in a lenticular lens and has a variety of uses, including sewing clothing and craft projects, such as scrap-booking.  The lenticular lens on lenticular fabric leads to a variety of effects, such as flip effect of images, 3D-depth, color-changing, motion, morph, zoom, explosion, etc.

Lenticular fabric has been utilized in clothing and accessories to create animated imagery and 3-D effects by fashion brands such as Walter van Beirendonck, Miu Miu, doublet, Christopher Kane, and Leeann Huang.  

Lenticular fabric is used to represent futuristic clothing in films and TV.  An example of lenticular fabric appears in the movie, Back to the Future Part II, in which Marty McFly wears a lenticular baseball cap.

Magnetic-plasmonic bifunctional nanoparticles. Magnetic-plasmonic (bifunctional) nanoparticles (MP-NPs) consist of both optical (plasmonic) and magnetic components and thus, has the functionality of both of these components. These nanoparticles may take many different forms/shapes including dimer, core-shell, janus, nanorod/wire and nanostar. Typically, the magnetic components consists of iron oxide or nickel while the plasmonic component is oftentimes a metal like gold, silver or another plasmonic nanomaterial. Due to the combination of these two materials into a hybrid nanostructure, the material may be interacted with using either light or magnetic fields and so, are commonly used in biomedical applications that require optical sensing/imaging/heating, magnetic stimulation/manipulation, or both of these functionalities. An example utilizing both of these functionalities is that MP-NPs can attach to biological entities and separate them under an external magnetic field while simultaneously detecting their chemical nature via optical sensing. These dual functionalities are especially useful when studying tissues deep within tissue.

Applications
Owing to their bifunctionality, magnetic-plasmonic nanoparticles can be used for a wide range of applications. For example, many of the applications of plasmonic nanoparticles including surface-enhance Raman scattering (SERS), dark-field microscopy, photothermal therapy, drug delivery, nanomedicine,  chemotherapy and plasmonic solar cells. As well as applications of magnetic nanoparticles including magnetic hyperthermia, magnetic resonance imaging contrast agent, and in magnetic drug delivery. Moreover, a number of applications could potentially be carried out simultaneously such as magnetic/optical dual-modal imaging.

Codec acceleration. Codec acceleration describes computer hardware that offloads the computationally intensive compression or decompression. This allows, for instance, a mobile phone to decode what would generally be a very difficult, and expensive video to decode it with no stuttering, and using less battery life than un-accelerated decoding would have taken. Similar acceleration is used on a broad variety of other appliances and computers for similar reasons. What could take a general purpose processor 100 Watts to decode on a general purpose processor, could take 10W on a graphics processing unit, and even less on a dedicated hardware codec.

Video codec acceleration
Video codec acceleration is where video (usually including audio as well) encoding and decoding is accelerated in hardware. Various vendors have developed their own video codec acceleration framework.

LFG Roland D.IX. The LFG Roland D.IX was a World War I German single seat fighter aircraft, a biplane powered by one of a new generation of powerful rotary engines.  Three slightly different prototypes were built but there was no series production.

Design and development

Late in 1917 new, more powerful rotary engines were appearing and the Idflieg encouraged aircraft manufacturers to incorporate them into fighters.  The D.IX was LFG Roland's response.  Apart from its engine it had much in common with the earlier D.VI, D.VII and D.VIII designs. It was a two bay biplane, with straight wings of constant chord and blunt tips.  The upper plane was a little larger in both span and chord, so the two interplane struts on each side diverged slightly upwards and leant gently outwards.  Bracing was assisted by flying and landing wires. There were ailerons on the upper wing only, the first and third prototypes using the overhung, balanced type and the second with unbalanced ones ending at the wing tip.

The D.IX had a fuselage of the Klinkerrumpf (clinker-built fuselage) type, roughly circular in cross section and built from overlapping longitudinal strips of spruce over a light, wooden frame, pioneered by LFG on the D.IV and used on the D.VI, D.VII and D.VIII. Because of the shortness and large diameter of the  Siemens-Halske Sh.III geared rotary of the first prototype, the nose of the new fighter was short and blunt compared with those of the earlier aircraft, which had all used liquid cooled V engines. Nonetheless, the metal oil deflecting cowling was carefully blended into the wooden fuselage. The rotary engine drove a four blade propeller, an unusual feature at this time and only fitted to one other LFG fighter, the later D.XVI.  The tailplane of the fighter was straight edged with blunt tips and slightly rounded, split elevators.  Its vertical tail repeated the small ventral fin of the D.VI and later Rolands and the rudder was similarly deep and rounded, but the tail surfaces of the second prototype were much enlarged and the rudder of the third horn balanced.  The D.IX's conventional undercarriage was of the single axle type, mounted on V-struts to the lower fuselage and with a tailskid attached to the ventral fin.

As well the ailerons and empennage revisions of the later prototypes, both were powered by the newer,  Siemens-Halske Sh.IIIa rotary.

Operational history
The first prototype flew in the first D type competition, held in January 1918, and performed well but was lost soon after in an accident in which the pilot's seat collapsed, followed by an inadvertent loop with g-forces that expelled him through the fuselage bottom.  The armed second prototype continued development and took part in the second D type competition held in May.  There it was judged not worthy of series production.

Lublin R-VII. Lublin R-VII Odwet () was a Polish heavy bomber design created by the Plage i Laśkiewicz factory in Lublin. One of the first heavy aircraft under the Lublin brand, it was designed following a 1924 specification for a "retribution bomber" by the Polish Ministry of Military Affairs. The project, led by Jerzy Rudlicki was a trimotor high-wing mixed-construction aeroplane with heavy defensive armament. The design was submitted to the ministry in 1924, but it was lost by the mail service. As no Polish aircraft factory was deemed experienced enough to build large, complicated bombers, the newly created 2nd Destroyer Squadron of the 1st Air Regiment was equipped with 32 Farman Goliath bombers bought in France. No drawings of the R-VII have survived, but it is known that the later Lublin R-XVIII was based on it.

This aircraft should not be confused with Lublin R-XI and Lublin R-XVI, both based on Fokker F.VII passenger plane, license-built in Poland by the same manufacturer.

Libhybris. libhybris is a compatibility layer for computers running Linux distributions based on the GNU C library or Musl, intended for using software written for Bionic-based Linux systems, which mainly includes Android libraries and device drivers.

History 
Hybris was initially written by Carsten Munk, a Mer developer, who released it on GitHub on 5 August 2012 and publicly announced the project later that month. Munk has since been hired by Jolla as their Chief Research Engineer.

Hybris has also been picked up by the Open webOS community for WebOS Ports, by Canonical for Ubuntu Touch and by the AsteroidOS project.

In April 2013, Munk announced that Hybris has been extended to allow Wayland compositors to use graphic device drivers written for Android. Weston has had support for libhybris since version 1.3, which was released on 11 October 2013.

Features 
Hybris loads "Android libraries, and overrides some symbols from bionic with glibc" calls, making it possible to use Bionic-based software, such as binary-only Android drivers, on glibc-based Linux distributions.

Hybris can also translate Android's EGL calls into Wayland EGL calls, allowing Android graphic drivers to be used on Wayland-based systems. This feature was initially developed by Collabora's Pekka Paalanen for his Android port of Wayland.

HB-E210 series. The  is a hybrid diesel multiple unit (DMU) train type operated by East Japan Railway Company (JR East) on Senseki-Tōhoku Line services in the Sendai area since 30 May 2015.

Design

Concept
The HB-E210 series trains were developed from the earlier KiHa E200 type operated on the rural Koumi Line, but to better suit commuter service operations, it incorporates both internal and external design elements from E129 series EMUs, like having three pairs of sliding doors per side and a mixture of transverse and longitudinal seating.

Hybrid diesel/battery operation cycle
Each car is equipped with a 331 kW 6-cylinder diesel engine and two banks of lithium-ion batteries with a capacity of 15.2 kWh when new. While at standstill, energy stored in the lithium-ion batteries is used to power auxiliary facilities on the train. On starting from standstill, energy stored in the batteries is used to drive the motors via an inverter, with the engine cut out. The engine then cuts in for further acceleration and running on gradients. When braking, the motor acts as a generator, recharging the batteries.

Livery
The exterior livery consists primarily of blue, the line colour for the Senseki Line, with pink highlights to evoke an image of the cherry blossom trees along the line, and smaller green highlights in JR East's corporate colour.

Bogies
Each car has one DT75B motored bogie (at the Sendai end) and one TR260B trailer bogie (at the Sekimaki end).

Operations

The HB-E210 series trains were introduced on 30 May 2015 on new Senseki-Tōhoku Line through services operating between  and  via a newly built link connecting the Tohoku Main Line and Senseki Line between  and .

Formations
The HB-E210 series fleet consists of eight two-car sets (16 vehicles), formed as shown below, with the HB-E211 car at the Sendai (eastern) end of the train.

Interior
LED lighting is used throughout. The HB-E211 cars have a universal access toilet at the inner end, and the HB-E212 cars have priority seats at both sides on the inner end. The floor height is , compared to the standard platform height of  for stations on the Senseki Line and  for stations on the Tohoku Main Line.

History

The first two trains built by Japan Transport Engineering Company (J-TREC) in Yokohama were originally scheduled to be delivered in November 2014, but the delivery date was postponed until January 2015. Test running using the first two sets delivered commenced on 16 January 2015, on the Tohoku Main Line between  and .

In May 2016, the HB-E210 series was awarded the 2016 Laurel Prize, presented annually by the Japan Railfan Club.

Build details
The build histories of individual sets are as follows.
