# Complete orthogonal decomposition

In linear algebra, the complete orthogonal decomposition is a matrix decomposition. It is similar to the singular value decomposition, but typically somewhat cheaper to compute and in particular much cheaper and easier to update when the original matrix is slightly altered.
Specifically, the complete orthogonal decomposition factorizes an arbitrary complex matrix $A$ into a product of three matrices, $A=UTV^{*}$, where $U$ and $V^{*}$ are unitary matrices and $T$ is a triangular matrix. For a matrix $A$ of rank $r$, the triangular matrix $T$ can be chosen such that only its top-left $r\times r$ block is nonzero, making the decomposition rank-revealing.
For a matrix of size $m\times n$, assuming $m\geq n$, the complete orthogonal decomposition requires $O(mn^{2})$ floating point operations and $O(m^{2})$ auxiliary memory to compute, similar to other rank-revealing decompositions. Crucially however, if a row/column is added or removed, its decomposition can be updated in $O(mn)$ operations.
Because of its form, $A=UTV^{*}$, the decomposition is also known as UTV decomposition. Depending on whether a left-triangular or right-triangular matrix is used in place of $T$, it is also referred to as ULV decomposition or URV decomposition, respectively.

## Construction

The UTV decomposition is usually computed by means of a pair of QR decompositions: one QR decomposition is applied to the matrix from the left, which yields $U$, another applied from the right, which yields $V^{*}$, which "sandwiches" triangular matrix $T$ in the middle.
Let $A$ be a $m\times n$ matrix of rank $r$. One first performs a QR decomposition with column pivoting:
    $A\Pi =U{\begin{bmatrix}R_{11}&R_{12}\\0&0\end{bmatrix}}$,
where $\Pi$ is a $n\times n$ permutation matrix, $U$ is a $m\times m$ unitary matrix, $R_{11}$ is a $r\times r$ upper triangular matrix and $R_{12}$ is a $r\times (n-r)$ matrix. One then performs another QR decomposition on the adjoint of $R$:
    ${\begin{bmatrix}R_{11}^{*}\\R_{12}^{*}\end{bmatrix}}=V'{\begin{bmatrix}T^{*}\\0\end{bmatrix}}$,
where $V'$ is a $n\times n$ unitary matrix and $T$ is an $r\times r$ lower (left) triangular matrix. Setting $V=\Pi V'$ yields the complete orthogonal (UTV) decomposition:
    $A=U{\begin{bmatrix}T&0\\0&0\end{bmatrix}}V^{*}$.
Since any diagonal matrix is by construction triangular, the singular value decomposition, $A=USV^{*}$, where $S_{11}\geq S_{22}\geq \ldots \geq 0$, is a special case of the UTV decomposition. Computing the SVD is slightly more expensive than the UTV decomposition, but has a stronger rank-revealing property.

While in the Florida Legislature, Clemons served as freshman class president, chairman of the telecommunications and utilities committee, and vice chairman of the banking and corporations committee. In the spring of 1998, Clemons announced his intent not to seek re-election in order "to focus on his business and spend more time with his family."
Clemons was born on February 13, 1960, in Panama City, Florida, and raised there as well. He graduated from Bay High School where he served as student body president. and attended the University of the South, where he served as president of the Student Assembly and received a B.A. He then went to Mercer University where he earned a J.D. degree.
After receiving his Juris Doctor, Clemons returned to Panama City and worked for the law offices of Bryant, Higby & Williams, concentrating primarily in insurance defense. Clemons currently serves as the president of The Clemons Company, Inc., an insurance agency, which was founded by his father, Gerry Clemons, in 1957. Clemons joined the company in 1991.
Clemons' charitable and civic service activities include positions on the board of directors of the United Way, Early Childhood Services, and Bay County Chamber of Commerce. Statewide service includes an appointment to the Florida Commission on Ethics.
Clemons is married to his wife, the former Pat Boss, and they have two children Katherine and Olivia.
In 2010, Clemons was one of a handful of prominent Florida Democrats to break with his party and endorse the Independent US Senate candidacy of Governor Charlie Crist, a former Republican, rather than Democratic nominee Kendrick Meek .

## 2007 Mayoral Election

After four successful runs as for the state legislature, Scott Clemons returned to politics when he announced in early 2007 his intentions to run against incumbent mayor Lauren DeGeorge. Two other men, Cliff Fleming and veteran city commissioner Bob Barnard also entered the race.
The News Herald reported on April 8, 2007, that Clemons was well in the lead for fundraising with the campaign. Clemons had raised $73,800; Barnard had raised $50,020; Fleming had raised $13,750 and the incumbent had raised $4,270.
Clemons and DeGeorge were the top vote getters in the April 17, 2007, initial election. Clemons went on to defeat DeGeorge in the May 15, 2007, runoff election. After the runoff election, new mayor Clemons made positive press when he offered to pay Boy Scout troops for the signs that they picked up.

# First Lady's Cup (Ghana)

The First Lady's Cup is an annual one-off game, featuring two selected clubs at the end of the season. The cup is called the GHALCA First Lady's Cup because it is organized by the Ghana League Clubs Association (GHALCA) and is played in honour of the sitting First Lady of Ghana.
The current holders are Hasaacas Ladies, who defeated rivals Ampem Darkoa Ladies 4–3 on penalties after the match ended in a 1–1 draw after full time in the 2021 maiden match.

## History

In early 2021, The Ghana League Clubs Association (GHALCA) began talks with Ghana Football Association (GFA) on the organization of the First Lady's Cup a female version of the President's Cup. They further set up a four-member committee to work on the competition including Anita Wiredu-Minta, a Ghanaian former international. In May 2021, GHALCA announced that arrangement for the organization of the First Lady's Cup has been concluded and formalized by the association's welfare body. The cup competition was launched on 5 November 2021. On 10 December 2021, the maiden edition was played at the Accra Sports Stadium with Hasaacas Ladies emerging victorious after a 4–3 penalty shootout after the match remained goalless after full time.

# Operation Cleaver

Operation Cleaver, as labelled in a report by American firm Cylance Inc. in late 2014, was a cyberwarfare covert operation targeting critical infrastructure organizations worldwide, allegedly planned and executed by Iran.
Cylance's report was later tacitly acknowledged in a confidential report by Federal Bureau of Investigation (FBI), though Iranian officials denied involvement in the operation.

## Cylance report

In December 2014, California-based cyber security firm Cylance Inc. published results of a 2-year investigation, an 86-page technical report, indicating that an operation, called "Operation Cleaver", has targeted the military, oil and gas, energy and utilities, transportation, airlines, airports, hospitals and aerospace industries organizations worldwide.
The title "Operation Cleaver" alludes to frequent uses of the word "cleaver" in the malware's coding.
According to the report, over 50 entities in 16 countries have been hit by the campaign, based in the United States, Israel, China, Saudi Arabia, India, Germany, France and England among others. Cylance's research does not name individual companies, but Reuters reports citing "a person familiar with the research" Navy Marine Corps Intranet, Calpine, Saudi Aramco, Pemex, Qatar Airlines and Korean Air were among the specific targets.
Stuart McClure, Cylance founder and CEO believes that the hackers are sponsored by Iran and have ties to Islamic Revolutionary Guard Corps.

## FBI report

According to Reuters, the Federal Bureau of Investigation has filed a confidential "Flash" report, providing technical details about malicious software and techniques used in the attacks. The technical document said the hackers typically launch their attacks from two IP addresses that are in Iran, but does not attribute the attacks to the Iranian government. FBI warned businesses to stay vigilant and to report any suspicious activity spotted on the companies' computer systems.

## Iran's reaction

Iran has officially denied involvement in the hacking campaign. "This is a baseless and unfounded allegation fabricated to tarnish the Iranian government image, particularly aimed at hampering current nuclear talks", said Hamid Babaei, spokesman for Permanent mission of Islamic Republic of Iran to the United Nations.
