From the Desire to Mark Essex: The Catalysts of Militarization for the New Orleans Police Department

Abstract The ultimate goal in the South was to end segregation, but nationwide equal-rights were the common goal of all African-Americans. Nonviolent protests and over aggressive police departments became the norm within the African-American community. Understated in the history of the Civil Rights Era is the role of armed resistance and Black Nationalism. Marcus Garvey, Stokely Carmichael, Huey P. Newton, and Malcolm X were Black Nationalists that led the charge of Black Nationalism worldwide. The Deacons of Defense, the Lowndes County Freedom Organization (LCFO) and the Black Panther Party for Self Defense transformed the social makeup of the country and became major causes of the militarization of police departments across the United States. Many police departments across America began to create SWAT teams and use military-style weaponry following an outbreak of riots and the assassination of Dr. Martin Luther King Jr. In New Orleans, Louisiana, stand-offs and shoot-outs with Black Panther members warranted a call for military backup, but it was the acts of Mark James Robert Essex that totally militarized the New Orleans Police Department

High-power single-frequency operation and efficient intracavity frequency doubling of a Nd:YAG ring laser, end-pumped by a 20W diode bar

The re-shaped output from a 20W cw diode-bar is used to longitudinally pump a Nd:YAG ring laser, resulting in a single-frequency output at 1.06µm of 5W and an intracavity frequency-doubled output at 532nm of 3W

High power 946nm Nd:YAG laser, longitudinally-pumped by a diode bar

We report efficient quasi-three-level operation of a Nd:YAG laser at 946nm pumped by a 20W diode bar. An output power of ~2.6W has been obtained for 14.4W of incident pump power

Appropriateness of oral anticoagulants for long-term treatment of atrial fibrillation in older people: results of an evidence-based review and international consensus validation process (OAC-FORTA 2016)

Background: Age appropriateness of anticoagulants for stroke prevention in atrial fibrillation is uncertain. Objective: To review oral anticoagulants for the treatment of atrial fibrillation in older (age >65 years) people and to classify appropriate and inappropriate drugs based on efficacy, safety and tolerability using the Fit-fOR-The-Aged (FORTA) classification. Methods: We performed a structured comprehensive review of controlled clinical trials and summaries of individual product characteristics to assess study and total patient numbers, quality of major outcome data and data of geriatric relevance. The resulting evidence was discussed in a round table with an interdisciplinary panel of ten European experts. Decisions on age appropriateness were made using a Delphi process. Results: For the eight drugs included, 380 citations were identified. The primary outcome results were reported in 32 clinical trials with explicit and relevant data on older people. Though over 24,000 patients aged >75/80 years were studied for warfarin, data on geriatric syndromes were rare (two studies reporting on frailty/falls/mental status) and missing for all other compounds. Apixaban was rated FORTA-A (highly beneficial). Other non-vitamin K antagonist oral anticoagulants (including low/high-intensity dabigatran and high-intensity edoxaban) and warfarin were assigned to FORTA-B (beneficial). Phenprocoumon, acenocoumarol and fluindione were rated FORTA-C (questionable), mainly reflecting the absence of data. Conclusions: All non-vitamin K antagonist oral anticoagulants and warfarin were classified as beneficial or very beneficial in older persons (FORTA-A or -B), underlining the overall positive assessment of the risk/benefit ratio for these drugs. For other vitamin-K antagonists regionally used in Europe, the lack of evidence should challenge current practice

Behavioral and morphological traits interact to promote the evolution of alternative reproductive tactics in a lizard

Alternative reproductive tactics (ARTs) are predicted to be the result of disruptive correlational selection on suites of morphological, physiological, and behavioral traits. ARTs are most obvious when they occur in discrete morphs with concomitant behav

High-power single-frequency operation, at 1064nm and 1061.4nm of a Nd:YAG ring laser end-pumped by a beam-shaped diode bar

A Nd:YAG laser having a ring configuration, with Faraday rotator to provide unidirectional operation has been end-pumped by a single 20 W diode bar equipped with a beam-shaper. A single-frequency TEMoo output of 5.4 W is achieved at 1064 nm. Using a thin intracavity etalon for wavelength selection, a single-frequency output of 4.2 W is obtained on the 1061.4 nm transition
