Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

The EL/M-2258 ALPHA ("Advanced Lightweight Phased Array") is a multi-function active electronically scanned array naval radar system. It was developed by IAI Elta, for maritime installation on medium-sized combat ships such as corvettes, frigates and larger vessels. It is capable of tracking both air and surface targets, providing fire control and splash spotting guidance with target classification. ALPHA is an acronym of Advanced Lightweight Phased Array Naval Radars.
The radar is installed in medium-sized combat ships of the Israeli navy.

M-ALPHA, also known as 3,4-methylenedioxy-α-ethyl-N-methylbenzylamine or as α-ethyl-N-methylpiperonylamine, is a psychoactive drug of the substituted benzylamine group. It was reported by Alexander Shulgin in his book PIHKAL as a positional isomer of MDMA. Subsequently, the drug was encountered as a designer drug in the United Kingdom in 2010 and was reported to the EMCDDA new drug monitoring service. It was described by Shulgin as similar in action to its demethylated homologue, ALPHA, but with roughly twice the duration and twice the potency. ALPHA itself was described as active at doses of 10 to 140 mg, with a duration of about 3 hours, and producing eyes-closed "dreams", some body tingling, and a pleasant positive feeling, but without any appetite suppression. M-ALPHA was encountered as a designer drug by 2010.

Calcium-activated potassium channel subunit alpha-1 also known as large conductance calcium-activated potassium channel, subfamily M, alpha member 1 (KCa1.1), or BK channel alpha subunit, is a voltage gated potassium channel encoded by the KCNMA1 gene and characterized by their large conductance of potassium ions (K+) through cell membranes.
In mathematics, the Struve functions Hα(x), are solutions y(x) of the non-homogeneous Bessel's differential equation: x 2 d 2 y d x 2 + x d y d x + ( x 2 − α 2 ) y = 4 ( x 2 ) α + 1 π Γ ( α + 1 2 ) {\displaystyle x^{2}{\frac {d^{2}y}{dx^{2}}}+x{\frac {dy}{dx}}+\left(x^{2}-\alpha ^{2}\right)y={\frac {4\left({\frac {x}{2}}\right)^{\alpha +1}}{{\sqrt {\pi }}\Gamma \left(\alpha +{\frac {1}{2}}\right)}}} introduced by Hermann Struve (1882). The complex number α is the order of the Struve function, and is often an integer. And further defined its second-kind version K α ( x ) {\displaystyle \mathbf {K} _{\alpha }(x)} as K α ( x ) = H α ( x ) − Y α ( x ) {\displaystyle \mathbf {K} _{\alpha }(x)=\mathbf {H} _{\alpha }(x)-Y_{\alpha }(x)} , where Y α ( x ) {\displaystyle Y_{\alpha }(x)} is the Neumann function. The modified Struve functions Lα(x) are equal to −ie−iαπ / 2Hα(ix) and are solutions y(x) of the non-homogeneous Bessel's differential equation: x 2 d 2 y d x 2 + x d y d x − ( x 2 + α 2 ) y = 4 ( x 2 ) α + 1 π Γ ( α + 1 2 ) {\displaystyle x^{2}{\frac {d^{2}y}{dx^{2}}}+x{\frac {dy}{dx}}-\left(x^{2}+\alpha ^{2}\right)y={\frac {4\left({\frac {x}{2}}\right)^{\alpha +1}}{{\sqrt {\pi }}\Gamma \left(\alpha +{\frac {1}{2}}\right)}}} And further defined its second-kind version M α ( x ) {\displaystyle \mathbf {M} _{\alpha }(x)} as M α ( x ) = L α ( x ) − I α ( x ) {\displaystyle \mathbf {M} _{\alpha }(x)=\mathbf {L} _{\alpha }(x)-I_{\alpha }(x)} , where I α ( x ) {\displaystyle I_{\alpha }(x)} is the modified Bessel function of the first kind.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
