John L. Harrington. John Lyle Harrington (December 7, 1868 – May 20, 1942) was an American civil engineer and a leading expert in the field of moveable bridge design.  He was a senior partner in several bridge engineering firms, President of the American Society of Mechanical Engineers in 1923-24, and Chief of the engineers' board advising the Reconstruction Finance Corporation.

Early life and family 
John L. Harrington was born on December 7, 1868, in Lawrence, Kansas to Robert Charles and Angeline Virginia (née Henry).  He attended public schooling in Kansas before graduating from the University of Kansas in 1895 with a Bachelor of Science (BS) in civil engineering.  In 1899 he married Daisy June Orton of White Cloud, Kansas before continuing his education at McGill University, where he completed a second BS in 1906, and a Master of Science (MS) degree in 1908.  As of 1911, Harrington and his wife resided in Kansas City, Missouri with one child: Thomas Orton Harrington.  Eventually, Harrington earned a Doctorate of Engineering from the Case School of Applied Sciences in 1930.

Career and works 
Early in his career, Harrington was Chief Engineer of the Locomotive and Machine Company of Montreal.  In 1907 he would partner with John Alexander Low Waddell to form the bridge design firm Waddell & Harrington.  Working together, they would soon obtain several patents improving on Waddell's earlier designs of the state-of-the-art vertical-lift bridge.   As of 2021, one of Harrington's early bridge collaborations with Waddell, the 1910 Hawthorne Bridge in Portland, Oregon, remains the oldest operating vertical-lift bridge in the United States.  The partnership came to an end in 1914 when Harrington departed along with draftsman Frank Morgan Cortelyou.  They joined a new company called 'Harrington, Howard & Ash', and in 1928 the duo went on to found the long-running firm Harrington & Cortelyou.  

In 1922 Harrington was elected president of the American Society of Mechanical Engineers for the year 1923-24. Under the Herbert Hoover presidency (1929–1933), he was a member of the Reconstruction Finance Corporation.

By the end of his career, Harrington was credited with having designed over 200 bridges and $100,000,000 worth of infrastructure (as of 1930).  Some of Harrington's notable creations include:

 Hawthorne Bridge (1910)
 ASB Bridge (1911)
 Colorado St. (Arroyo Seco) Bridge (1913)
 Murray Morgan Bridge (1913)
 Champ Clark Bridge (1928)
 Sarah Mildred Long Bridge (1940)

Death 
John Harrington died on May 20, 1942, in Kansas City. He is buried at Forest Hill Calvary Cemetery.

Nanopore battery. A nanopore battery is a rechargeable battery that is a composite of billions of nanoscale batteries formed within the pores of a substrate.

The space inside the holes is so small that billions of pores combined equal the volume of a grain of sand. Each pore's diameter was some one eighty-thousandth the width of a human hair.

Construction 

In 2014 a demonstration device was made from a ceramic sheet made of anodic aluminum. It held two vanadium pentoxide nanotube electrodes separated by an electrolyte that carried the electrical charge between the two. The current collector was made of ruthenium. The individual batteries are connected in parallel.

The  is prelithiated at one end to form the anode, with pure  at the other end to form the cathode. The battery asymmetrically cycles between 0.2 V and 1.8 V.

Performance 

The capacity retention of this full cell (relative to 1 C values) is 95% at 5 C and 46% at 150 C, with a 1,000-cycle life. A demonstration device was fully charged in 12 minutes and recharged thousands of times.

Implications 

The system uses an electrochemical regime in which ion insertion and surface charge mechanisms for energy storage become indistinguishable. It can serve as a vehicle for studying ion transport limits in dense, nanostructured, electrode arrays.

CASIC WJ. CASIC WJ is a series of unmanned aerial vehicles (UAVs) developed by the 3rd Academy Hiwing (HW for short, ) of the China Aerospace Science and Industry Corporation (CASIC), and the academy is also more commonly known as HiWING Mechanical and Electrical Technology Corp., () or HiWING for short.

WJ-010
WJ-010 UAV is a development of the unarmed CASIC HW-100 Sparrowhawk, and the two UAVs share the identical layout. As an armed version, WJ-010 utilizes modular design concept to enable the rapid replacement two different kinds of payload: the first payload is the optical payload for reconnaissance, and with this payload, WJ-010 functions as an ordinary scout UAV. The second payload is a warhead, and when armed with this payload, WJ-010 functions as a suicide attack UAV.

WJ-100 Blade
WJ-100 Blade (Dao-Feng or Daofeng, 刀锋) is the latest model (as of early of 2015) of Blade series UAV developed by CASIC, which includes several other models such as CASIC HW-300 and CASIC SF-460. As with other member of Blade series UAV, WJ-100 is also in twin boom layout with high wing configuration and tricycle landing gear. The winglets of WJ-100 is larger in comparison to some earlier model of Blade series. Propulsion is provided by a two-blade propeller driven pusher engine mounted at the rear end of the fuselage.

WJ-500
WJ-500 is a jet powered UAV developed by CASIC intended for various missions, such as targeting, reconnaissance, target damage assessment, and simulation of cruise missiles and aircraft. WJ-500 has a cylindrical fuselage with inlet atop the empennage. Wing tip tank can be installed on the main wing. WJ-500 made its public debut in November 2014 at the 10th Zhuhai Airshow.

WJ-600 A/D
WJ-600 A/D is a development of CASIC HW-610 and CASIC HW-600 Sky Hawk (WJ-600), and in comparison to its predecessors that is either a reconnaissance only version or a ground attack only version, WJ-600 A/D incorporates both the reconnaissance and ground attack capability so that it can perform both missions, and hence A/D in its name stands for attack drone. WJ-600 A/D is designed to carry out both the reconnaissance mission of WJ-600 and the ground attack mission of HW-610 in a single platform. Specification:
Endurance (hr): 5
Speed (km/h): 850
Propulsion: turbofan

On 27 October 2016, two WJ-600A/Ds were spotted in a military parade in Turkmenistan, the first confirmed export.

WJ-700
At the 2018 Zhuhai Airshow, CASIC unveiled a medium-/high-altitude long-endurance (MALE/HALE) armed reconnaissance unmanned aerial vehicle named WJ-700 with a maximum takeoff weight (MTOW) of 3,500 kg and an endurance of up to 20 hours. It has four underwing hardpoints and can carry CM-102 anti-radiation missile, C-701, and C-705KD anti-ship missiles, but also land attack munition.

CASIC HW-600 series UAV. CASIC HW-600 series unmanned aerial vehicles are Chinese UAVs developed by 3rd Academy Hiwing (or HW for short, 海鹰in Chinese) of China Aerospace Science and Industry Corporation (CASIC), and this academy is also more commonly known as  HiWING Mechanical and Electrical Technology Corp, (海鹰机电技术研究院, the exact literal translation of its Chinese name is actually Sea Eagle Mechanical and Electrical Technology Research Academy) or HiWING for short.

HW-600 Sky Hawk (WJ-600)
HW-600 Sky Hawk (Tian-Yi or Tianying, 天鹰), this HiWING developed UAV is a jet-powered UCAV. The turbojet powered HW-600 Sky Hawk has a conventional layout with high-wing configuration and small winglets.  The engine is in the aft section of the cylindrical fuselage, and the inlet is atop of the fuselage at the root of the single vertical tail fin. There is a single hardpoint under each wing, which is designed to carry a variety of Chinese UAV employed missiles and other munitions. Sensors are presumably stored in the bulbous nose.  Also known as WJ-600, there are Chinese internet claims that HW-600 is the designation for the unarmed reconnaissance version, while WJ-600 is the designation for the armed UCAV version.  However, such unconfirmed claims have yet to be verified by official governmental / industrial / independent sources.  Reportedly, WJ is short for Wu-Jian (无歼), short for Wu-Ren Jian-Ji-Ji (无人歼击机), meaning unmanned fighter because MANPADs can be deployed by this UCAV as air-to-air missiles. Specification:
Speed: 200 m/s
Ceiling: 10 km
Operational range: 2100 km
Launch: rocket
Recovery: parachute

Junctionless nanowire transistor. Junction-Less nanowire transistor (JLNT) is a type of Field-effect transistor (FET) in which the channel consists of one or more nanowires and does not contain a junction.

Existing devices
Multiple JLNT devices were manufactured in various labs:

Tyndall National Institute in Ireland
JLT is a nanowire-based transistor that has no gate junction. (Even MOSFET has a gate junction, although its gate is electrically insulated from the controlled region.) Junctions are difficult to fabricate, and, because they are a significant source of current leakage, they waste significant power and heat. Eliminating them held the promise of cheaper and denser microchips. The JNT uses a simple nanowire of silicon surrounded by an electrically isolated "wedding ring" that acts to gate the flow of electrons through the wire. This method has been described as akin to squeezing a garden hose to gate the flow of water through the hose. The nanowire is heavily n-doped, making it an excellent conductor. Crucially the gate, comprising silicon, is heavily p-doped; and its presence depletes the underlying silicon nanowire thereby preventing carrier flow past the gate.

LAAS
A Junction-Less Vertical Nano-Wire FET (JLVNFET) manufacturing process was developed in Laboratory for Analysis and Architecture of Systems (LAAS).

Electrical Behaviour
Thus the device is turned off not by reverse bias voltage applied to the gate, as in the case of conventional MOSFET but by full depletion of the channel. This depletion is caused due to work-function difference (Contact_potentials) between the gate material and doped silicon in the nanowire.

The JNT uses bulk conduction instead of surface channel conduction. The current drive is controlled by doping concentration and not by gate capacitance.

Germanium has been used instead of silicon nanowires.

Ya-Ali (missile). The Ya-Ali (Persian: یاعلی) is an air-launched cruise missile (ALCM) built by Iran. 
The missile was first unveiled on 11 May 2014 when Iranian leader Grand Ayatollah Ali Khamenei visited the Aerospace Force of the Army of the Guardians of the Islamic Revolution. According to Janes Defence, the missile has a jet engine inlet and possibly uses a version of the Toloue-4 turbojet or different Toloue 10 or 13 engines Iran produces for its longer-range anti-ship missiles and it is reported to have a range of 700 km. On February 7, 2015, Iran's Deputy Defense Minister Mohammad Eslami announced that the missile could previously be launched from only Mirage type fighter planes but it can now be launched from every fighter plane that Iran owns. It is named after a Shi'i religious expression beseeching  imam Ali.

As an ALCM, the Ya-Ali is distinct from the ground launched cruise missiles (GLCMs) in the Houthi inventory. According to Jane's Defense Weekly, the Houthis may have used a Quds 1 GLCM in the Abha International Airport attack on 12 June 2019. This airport in southwestern Saudi Arabia is less than 200 km from the Yemeni border. The Iranian Ya-Ali has a much longer range due to being imparted with much more kinetic and potential energy when released from a fighter aircraft such as the Mirage type. The Houthis have no fighter aircraft in their inventory.

Jane's Defense Weekly reported on September 16, 2019 that, according to US officials, "There are indications that the 14 September attack on two oil facilities in Saudi Arabia were carried out using cruise missiles launched from Iraq or possibly Iran."   It went on to say "the impact points showed the weapons approached from the west northwest, rather than Yemen, as claimed by the Iranian-backed Yemeni rebel group Ansar Allah (Houthis). 'It is very difficult to see how these things could have come from anywhere but Iran or Iraq,' CNN quoted the official as saying." Some of the targets struck on September 14, 2019 were oil processing facilities at Abqaiq, Saudi Arabia. Abqaiq is located near Bahrain, is approximately 1,000 km from the Houthi-controlled portion of Yemen, and is approximately 300 km from Iran.

Google Kythe. Google Kythe is a source code indexer and cross-referencer for code comprehension which describes itself as a "pluggable, (mostly) language-agnostic ecosystem for building tools that work with code".

The entirety of the Google team working on Kythe was laid off in April 2024, as part of a company push to move certain roles overseas.

Overview
The core of Google Kythe is in defining language-agnostic protocols and data formats for representing, accessing and querying source code information as data. Kythe relies on an instrumented build system and compilers that produce indexing information, semantic information and metadata in Kythe specified format. This information obtained from running an instrumented build is stored in a language-agnostic graph structure. Finally, this graph structure can be queried to answer questions about the code base.

Google Kythe is an open-source project being developed by Google. It is licensed under an Apache licence 2.0.

Grok
Google Kythe originates from an internal project called Grok.

Grok had been proposed by Steve Yegge in 2008. Yegge observed that software projects routinely use more than 3 programming languages, yet development tools tend to be language specific and don't handle multiple programming languages well. Adding support for a language to an IDE is hard and the ad hoc analysis tools in IDEs tend to be inferior to real parsers and compilers.

Some parts of Grok were publicly released even before Google Kythe was announced. In 2010, Google released a Python static analyzer which has been developed as part of Grok.

In 2012, C++, Java, Python, JS and "2 internal languages" were supported by Grok. There was a browser client with support for querying the database and visually navigating through the source code. There was an Emacs client.

Chromium Code Search Browser uses Grok index to provide quick links to definition for every symbol in the source code.

Scania OmniLine. The Scania OmniLine was a single-deck intercity bus manufactured by Scania between 2000 and 2009. It was launched as the first normal-floor member of the Scania Omni range with the first buses being delivered in 2000. It was first produced by DAB in Silkeborg, Denmark, and was also technically just a facelift from DAB's latest model, which was known as the DAB Facelift. The technical name for the model was Scania IL94IB (IL94IB4X2NB230 to IL94IB4X2NB300, depending on power output), which indicates that it was built on the L94IB chassis. It was available in lengths of 12.0 and 13.5 metres and a floor height of 960 mm. In 2003, Scania sold the Silkeborg plant to Norwegian bus builder Vest Busscar, and production of the OmniLine was moved to Baltcoach OÜ in Tartu, Estonia.

In October 2005, Scania presented their new Euro IV compliant models, and the new second generation OmniLine got a facelift with double circular headlights, compared to the old rectangular ones from the first generation, and some other visual upgrades. The change of model did however not happen until 2006. Since the L94IB chassis was replaced by the K IB chassis, the technical name for the OmniLine was also changed to Scania IK IB. With power outputs, it was from 2006 available as the IK 270 IB (IK 270 IB4x2NB), IK 310 IB (IK 310 IB4x2NB) and IK 340 IB (IK 340 IB4x2NB), and from 2008 also as the IK 280 IB (IK 280 IB4x2NB). The second generation was available in lengths of 10.8, 12.0 and 12.7 metres, and floor heights of 860 and 970 mm.

The production in Tartu ended in 2007, and in 2008 the production was done at Scania's main bus plant Scania Production Słupsk S.A. in Słupsk, Poland. However, later that year production was moved to the Scania Peter OOO plant in St. Petersburg, Russia. In 2009, Scania decided to stop the production of the model because of low sales volumes. In total only around 450 buses had been built during almost a decade. The decision to end the production seems to have been quite sudden, as Norwegian operator Nordlandsbuss had ordered a batch of OmniLines, that instead were built as the slightly taller OmniExpress 3.40 (3.40 m).

There was no immediate successor to the OmniLine available when production ended. Customers were offered the slightly taller versions of the OmniExpress, but it wasn't until Scania two years later, in 2011 introduced the 3.31-metres tall OmniExpress 3.20 with a floor height of 860 mm that they offered a model similar to the OmniLine.
