Hidden linear function problem. The hidden linear function problem, is a search problem that generalizes the Bernstein–Vazirani problem. In the Bernstein–Vazirani problem, the hidden function is implicitly specified in an oracle; while in the 2D hidden linear function problem (2D HLF), the hidden function is explicitly specified by a matrix and a binary vector. 2D HLF can be solved exactly by a constant-depth quantum circuit restricted to a 2-dimensional grid of qubits using bounded fan-in gates but can't be solved by any sub-exponential size, constant-depth classical circuit using unbounded fan-in AND, OR, and NOT gates.
While Bernstein–Vazirani's problem was designed to prove an oracle separation between complexity classes BQP and BPP, 2D HLF was designed to prove an explicit separation between the circuit classes  and   ().

2D HLF problem statement 
Given (an upper- triangular binary matrix of size ) and  (a  binary vector of length ),

define a function :

There exists a  such that

 

Find .

2D HLF algorithm 
With 3 registers; the first holding , the second containing  and the third carrying an -qubit state, the circuit has controlled gates which implement 
 from the first two registers to the third.

This problem can be solved by a quantum circuit, , where H is the Hadamard gate, S is the  S gate and CZ is  CZ gate. It is solved by this circuit because with ,  iff  is a solution.

J. Torkel Wallmark. John Torkel Wallmark (4 June 1919 – 5 February 2007) was a Swedish electrical engineer and researcher in semiconductor electronics and innovation technology.

Torkel Wallmark was born in Stockholm. He graduated from the Royal Institute of Technology in 1944, became technology licentiate in 1947 and technology doctor in 1953. He was then a researcher at Radio Corporation of America in Princeton, US 1953–1964.

In 1964, he returned to Sweden as a professor in solid state electronics at Chalmers University of Technology. (The professorship was initially named electron physics III.) In 1983 he transferred to a personal professorship in innovation technology at Chalmers, which was the first in this subject area in Sweden. Torkel Wallmark's business in innovation technology has contributed to the establishment of seed companies based on research at Swedish technical colleges, especially Chalmers.

Torkel Wallmark was elected as a member of the Swedish Academy of Sciences in 1970 and became a member of the Academy of Sciences in 1984. He was awarded the 1982 Polhems Prize for research in the field of solid state electronics, 1989 KTH's grand prize for building an innovation center at Chalmers, and 1989 The Academy of Engineering Sciences major gold medal with the motivation "for his internationally outstanding efforts in semiconductor technology and his incentive for industrial new enterprise"''.

Taqsem A. Khan. Taqsem A. Khan is an engineer and a former managing director and CEO of Dhaka WASA, a government owned company responsible for water and sewage in the capital of Bangladesh, Dhaka from 2009 until 2024. He has been appointed five consecutive times in that same post since 2009 until his resignation on 14 August 2024, at the aftermath of the 2024 non-cooperation movement.

Early life
Khan graduated from St. Gregory's High School and College. He did his master's in mechanical engineering at a University in Moscow. He joined Philips Bangladesh as a production engineer.

Career
Khan served as the chief engineer of International Centre for Diarrhoeal Disease Research, Bangladesh from 1988 to 1998.

On 14 October 2009, he was appointed the managing director of Dhaka WASA. He has extended his tenure as the Managing Director of WASA five times.

On 21 October 2019, his comments saying WASA water in 100 percent pure were criticized in parliament by the parliamentary standing committee on public undertakings. According to Muhibur Rahman Manik, a member of the committee, Khan was criticized for the water not being safe and his comments. Bangladesh High Court in December 2009 criticized his comments saying that there were no sewage lines to Buriganga River. The court had directed WASA to close all sewage lines flowing to the river to reduce pollution in 2011. The court found his statement to be false. On 23 January 2020, Bangladesh High Court issued a contempt of court ruling against him for disobeying High Court directive and lying in court. The High Court observed that he was voluntarily refusing to obey the court directives.

Manjur Ahmed Chowdhury, chairman of the National River Conservation Commission, called for the jailing of Atiqul Islam, mayor of North Dhaka City, and Taqsem A Khan for failing in their duties to protect rivers.

On 14 August 2024, Taqsem A Khan resigned from his position as the managing director of Dhaka WASA. According to WASA executive engineer Badrul Alam, Taqsem stepped down due to health issues.

Controversy
In 2016, Khan was interrogated by the Bangladesh Anti Corruption Commission over financial irregularities. According to banglanews24.com, there are allegations against him of embezzling 2 thousand crore from 10 mega projects of Dhaka WASA. He has faced questions over irregularities in the implementation of Padma Jashaldia water treatment plant project, a mega project of Dhaka WASA.

Personal life
Taqsem has a US citizenship along with his wife and children.

Citroën 19 19 Concept. The Citroën 19_19 Concept is a futuristic electric concept car developed by the French manufacturer Citroën presented on the occasion of its centenary.

Presentation 
The 19_19 Concept was presented on 13 May 2019 at the Viva Technology show at the Paris expo Porte de Versailles, in Paris. The Citroën 19_19 celebrates the centenary of the manufacturer founded on 20 June 1919. It follows on from the Ami One concept car presented at the 2019 Geneva Motor Show which also celebrates Citroën's 100th anniversary.

Premise 
The 19_19 Concept was designed with the primary premise of acting as a futuristic demonstration of an electric vehicle with an emphasis on comfort. According to Citroën, the vehicle would have a range of comfort-centric features, including a "smart suspension system", heated seats, a digital personal assistant, individual sound zones for each passenger and others, on top of 800 km of range, Level 4 Autonomy as per the classifications introduced by SAE International, a 0 to 60 mph time of 5 seconds and a top speed of 200 km/h.

Design 
According to Citroën, the 19_19 Concept's design was inspired by aerospace, with what the manufacturer calls a "double prospex bonnet" housing LED headlights that span the front of the vehicle, forming the brand's logo at its center, located above the "Origins" logo. The rear of the vehicle features tail lights that echo the format of the headlights, located between a pair of Lidar sensors located along the back of its roof and a window into some of its internal components. Citroën describes the car's body as resembling a "transparent capsule", and highlights its black and blue color scheme as a nod to the Petite Rosalie. The 19_19 Concept was equipped with 30" wheels (total diameter, including tires of 930mm) designed in conjunction with the Goodyear Tire and Rubber Company, featuring rotating centers that keep the Origins logo upright.

Am Rank (Röhmsee). Am Rank (Röhmsee) is a nature conservation area, designated by decree of the Regional Council Stuttgart of 16 November 1981, in the Unterensingen municipality of District Esslingen in Baden-Württemberg, Germany. It includes and surrounds a quarry pond named Röhmsee, after a former owner.

Together with the Schülesee, the 13-hectare Röhmsee forms a protected area of about 25 hectares. The lakes are a supra-regionally important ecological compensation area with well-developed siltation zones. Lake Röhmsee is important as a resting place for migrating birds and as a refuge for endangered bird species. As the oldest quarry pond still existing in the Neckar river system, it has developed into an important breeding water for birds. Among others, the bittern, the marsh warbler, the coot and the moorhen breed here. The Unterensingen quarry ponds occupy an excellent position as a transit and resting area. In the meantime, 223 species have been recorded in this relatively small area.

The area belongs to the Naturraum Filder in the Swabian Keuper-Lias-Land.
