Skyeton Raybird-3. Raybird-3 (ACS-3) is an unmanned aircraft system designed for various long-term missions and ISTAR operations. It corresponds to the class I of NATO classification and the Armed Forces of Ukraine. Created by APC "Skyeton". Raybird-3 is the name of the aviation system for dual-use; ACS-3 is the name of the military version.

History of UAV creation and development 
In 2014, the first prototype of fixed-wing UAV was developed, with a gasoline engine for surveillance and inspection missions.

Later, a number of state tests confirmed that the complex carries out necessary tasks in the conditions of counteraction to electronic warfare (EW) and meets the requirements for tactical drones.

In October 2020, an upgraded modification of the ACS-3M was introduced with a new injector engine, improved software, and an ability to mount a small radar with a synthesized aperture.

In March 2021, the launch of a UAV from a moving object (vehicle in motion) was demonstrated.

Since 2016, the UAV has been allowed to operate in the Armed Forces of Ukraine. Also, the UAV manufacturer is included in the register of executors of the state defense order of Ukraine.

Design 
Unmanned aerial system Raybird-3 consists of an unmanned aerial vehicle, a portable ground control station, an antenna, and a catapult. The whole complex is transported in four containers. It takes less than 20 minutes to start.

UAV power plant is a single-cylinder four-stroke gasoline engine GF40 injector type with a capacity of 40 cm3 (manufactured by OS Engines), which drives the propeller. The engine operates in temperatures from −25 to +45 °C, its power is 3.8 hp (2.8 kW). The aircraft is launched by a mechanical catapult with a starting speed of 55 km/h. It lands on a parachute.

The UAV does not require manual entry of coordinates, flies on a pre-programmed route, and returns to the operator. The operator does not need to directly control the aircraft and the whole system operators under autopilot command at all times. The maximum distance of the control link is 240 km. In offline mode Raybird-3 flies 2.5 thousand km at a maximum radius of 1 thousand km. Any number of aircraft can be connected to the control station, any number of operators can be connected to one aircraft.

Pedestrian Bridge (Chernihiv). The pedestrian bridge () is a bridge over the Desna river in the city of Chernihiv, Ukraine, for pedestrian traffic.

History
The Pedestrian Bridge is of the largest bridges in Chernihiv. It is the only pedestrian bridge across the Desna in the city of Chernihiv.

Administratively the bridge is located within the city of Chernihiv.  It connects the left and right banks of the Desna.  It is located next to beaches and to the Chernihiv river port. Special barriers prevent vehicles from passing through.

The bridge was built in 1987 by the NP Melnikov Central Research and Design Institute of Building Metal Structures.

In 2014, the rails were painted by activists in alternating stripes of yellow and blue. The bridge has been used as a site for bungee jumping.  Some have publicly proclaimed their love there, on special, heart shaped metal structures made for the purpose. 

On 23 March 2022, due to the Siege of Chernihiv by the 2022 Russian invasion of Ukraine the Kyiv Bridge for vehicle traffic was destroyed.  For the subsequent for 2 weeks, the only option to leave the city across the Desna was the pedestrian bridge, so people set out on foot to get to Anisov and Kulykivka through fields. During the siege, the Pedestrian Bridge was also damaged.  "In view of this, a joint decision was made with the Chernihiv Regional State Administration to limit traffic on this bridge as much as possible. Traffic is prohibited, only pedestrian crossing," operational command "North" said in a statement.
"()" As an exception, cars with the most necessary things for the defenders of Chernihiv were allowed.

Interning (computer science). In computer science,  interning is re-using objects of equal value on-demand instead of creating new objects. This creational pattern is frequently used for numbers and strings in different programming languages. In many object-oriented languages such as Python, even primitive types such as integer numbers are objects. To avoid the overhead of constructing a large number of integer objects, these objects get reused through interning.

For interning to work the interned objects must be immutable, since state is shared between multiple variables. String interning is a common application of interning, where many strings with identical values are needed in the same program.

History 
Lisp introduced the notion of interned strings for its symbols. The LISP 1.5 Programmers Manual  describes a function called intern which either evaluates to an existing symbol of the supplied name, or if none exists, creates a new symbol of that name. This idea of interned symbols persists in more recent dialects of Lisp, such as Clojure in special forms such a (def symbol) which perform symbol creation and interning.

In the object-oriented programming paradigm interning is an important mechanism in the flyweight pattern, where an interning method is called to store the intrinsic state of an object such that this can be shared among different objects which share different extrinsic state, avoiding needless duplication.

Interning continues to be an important technique for managing memory use in programming language implementations; for example, the Java Language Specification requires that identical string literals (that is, literals that contain the same sequence of code points) must refer to the same instance of class String, because string literals are "interned" so as to share unique instances. In the Python programming language small integers are interned, though the details of exactly which are dependent on language version.

Motivation 
Interning saves memory and can thus improve performance and memory footprint of a program. The downside is time required to search for existing values of objects which are to be interned.

Isomorphic Labs. Isomorphic Labs Limited is a London-based company which uses artificial intelligence for drug discovery.  Isomorphic Labs was founded by Demis Hassabis, who also serves as the CEO. The company was incorporated on February 24, 2021 and announced on November 4, 2021. It was established under Alphabet Inc. as a spin-off from its AI research lab DeepMind, of which Hassabis is also founder and CEO.

The company draws upon DeepMind's AlphaFold technology, which can be used to predict protein structures in the human body with high accuracy, allowing its researchers to find new target pathways for drug delivery.

In December 2022, Isomorphic Labs announced its second office location in Lausanne, Switzerland.

In January 2024, Isomorphic Labs partnered with Novartis AG and Eli Lilly and Company to work together on AI drug discovery and research.

In May 2024, Google DeepMind and Isomorphic Labs announced the release of AlphaFold 3, freely available on the AlphaFold server for non-commercial research. AlphaFold 3 is not limited to predicting how proteins fold, it can also predict the interactions with molecules typically found in drugs such as ligands or antibodies, which is expected to significantly accelerate drug discovery.

In November 2024, preliminary results of CASP16 showed AlphaFold 3-based models did not significantly outperform older methods for predicting protein-ligand interactions. The top performing models in the CASP16 Pose Prediction for Pharma Targets section were ClusPro and CoDock utilizing AlphaFold 2 based predictions, human visual inspection, and manual adjustments.

Alternative fuel locomotive. An alternative fuel locomotive refers to a locomotive that is not powered by oil or coal based fuels. In the 21st century, a variety of technologies are being experimentally tried as alternative fuels, including hydrogen, liquified natural gas, and compressed natural gas.

Types

Hydrogen 

In the United States, BNSF Railway tested a hydrogen powered switcher locomotive in 2008 and 2009, in partnership with the United States Army.

Battery electric 

Several railroads have tested battery electric locomotives, which operate based on rechargeable batteries and have zero greenhouse gas emissions. Compared to conventional diesel locomotives, battery electric locomotives are quieter and cleaner, but require charging stations to support their use. At least one instance of a battery electric locomotive, for the Bessemer and Lake Erie Railroad, was funded by a state government grant supporting improvements to air quality. As of 2022, battery electric locomotives are only a small part of the locomotive fleet in North America, which numbers approximately 39,000.

Jean Hupeau. Jean Hupeau (1710 - Paris, 10 March 1763) was a French architect and engineer best known for building the George V Bridge in Orleans.

Biography 
In 1731 he was appointed engineer of the généralité of Riom and then of that of Soissons. On May 8, 1742, he was appointed inspector of bridges and roads, and in 1754, first engineer to replace Germain Boffrand.

His art was recognized and on January 10, 1757, he was elected to the Académie royale d'architecture. He died on March 10, 1763, after a long illness and was replaced by Jean-Rodolphe Perronet as a case of the Corps des Ponts et Chaussées.

Works 
In 1750, he drew up the project for the Orléans Bridge. The bridge was not built in the Rue de Recouvrance, but upstream 49 meters allowing to trace, in perfect alignment, the Rue Royale with Avenue Dauphine. The traffic design is harmonious and you can see the work of an urban planner.

For this project he succeeded Robert Pitrou, also an inspector general, who had already designed the same bridge. He questioned the previous project and proposed a more economical design: a bridge with 9 arches instead of 11 and a length of 165 meters instead of 189.

He was an architect who perfectly adapted the work to its destination and site. He had a sense of visual pleasure, a pleasure born largely of habit that led him to harmoniously combine the best projects he had already seen. For the ramps he chose the minimum value, as Louis de Règemorte had done at Moulins. The final result is of great nobility and simplicity, which led him to remove, during the execution of the works, the obelisk foreseen in the project. The pavilions and facades of the Rue Royale, also by his hand, are in the same classical style.

A few years later he directed the construction of the bridges of Joigny and Cravant on the Yonne River and those of Montereau and Mantes on the Seine.

Finally, he designed the Trilport bridge over the Marne, a project of a bridge with three low arches with spans of 26 meters, and whose piers formed an angle of 72 degrees with the axis of the bridge. Hupeau's design was adopted in preference to a design by Perronet, and the work was directed by Chézy.

Since the delivery of the George V bridge in Orleans was to be made one year after the start of the work, the difficulties encountered lead to a postponement of this deadline by two years. Thus the builder Jean Hupeau, who died on March 10, 1763, in Paris, left the completion of his main work to his successor.

Avibras A-80 Falcão. 

The Avibras A-80 Falcão was a training aircraft from the Brazilian manufacturer Avibras.

Design and development
The A-80 Falcão was developed as a beginner trainer aircraft for the Brazilian Air Force, but the latter opted for the Aerotec A-122 Uirapuru, so only one prototype was built.

The aircraft was designed as a low-wing monoplane with a conventional tailplane and had a non-retractable nose wheel landing gear. The aircraft was of wooden frame construction covered with synthetic fabric. The instructor and student pilots sat in an enclosed cockpit, the canopy of which could be slid rearward for entry.
