us_congress: US Congressional co-sponsorship (1973-2016)
Two temporal networks of bill co-sponsorship tendencies among US Congresspeople, from 1973 (93rd Congress) to 2016 (114th Congress). Edges are signed, indicating the presence of a significant tendency to co-sponsor, or tendency to not co-sponsor, bills. Two networks per year, one for each chamber (House, Senate). Each file contains the signed network for a chamber of congress (H = House, S = Senate) in one session (e.g. 93 = 93rd…

Hamilton cycles in tough $(2P_2 \cup P_1)$-free graphs
In 1973, Chvátal conjectured that there exists a constant $t_0$ such that every $t_0$-tough graph on at least three vertices is Hamiltonian. While this conjecture is still open, work has been done to confirm it for several graph classes, including all $F$-free graphs for every 5-vertex linear forest $F$ other than $P_5$ and $2P_2\cup P_1$. In this note, we show that 11-tough $(2P_2 \cup P_1)$-free graphs on at least three vertices are Hamiltonian.

Wow the cover of the 1973 Hew Report (precursor to 1974's Data Privacy Act) is *wild*. https://ia601702.us.archive.org/8/items/recordscomputers00unit/recordscomputers00unit_jpg.pdf

Jag reflekterar över varför jag gör det jag gör och hur jag vill nyttja min tid. Mitt skrivande är mitt kall, och tillsammans med mina modeller och visualiseringar är det så just jag kan bidra. Nu kan du som vill och har förmåga också backa det arbetet.

#NowPlaying - my proper canterbury education carries on with henry cow's 1973 debut, like "weasels ripped my flesh" era mothers, but british leftist instead of californian libertarian (not that they really sing much here) & a notch less manic.

Here's a document that deserves to be remembered, resurrected, and read (hey, that's 3 "R's!).

Advent of Computing
Welcome to Advent of Computing, the show that talks about the shocking, intriguing, and all too often relevant history of computing. A lot of little things we take for granted today have rich stories behind their creation, in each episode we will learn how older tech has lead to our modern world.

Heute vor 52 Jahren: Am 06.06.1973 zündeten die USA im Rahmen von Operation Toggle die Atombombe "Almendro". Toggle war eine Serie von #Kernwaffentests bei der 72/73 insgesamt 35 Bomben größtenteils im Testgebiet in #Nevada und Rio Blanco unterirdisch gezündet wurden.

Heute vor 51 Jahren: Am 6. Juni 1974 führten die #USA in #Nevada den #Atomtest "Jara", Teil der "Operation Arbor", durch. Bei dieser Operation wurden 1973/74 20 Atomtests unterirdisch du…

On the quadratic 8-edge case of the Brown-Erdős-Sós problem
Let $f^{(r)}(n;s,k)$ be the maximum number of edges in an $n$-vertex $r$-uniform hypergraph containing no $k$ edges on at most $s$ vertices. Brown, Erdős and Sós conjectured in 1973 that the limit $\lim_{n\rightarrow \infty}n^{-2}f^{(3)}(n;k+2,k)$ exists for all $k$. Recently, Delcourt and Postle settled the conjecture and their approach was generalised by Shangguan to every uniformity $r\ge 4$: the limit $\lim_{n\rightarrow \infty}n^{-2}f^{(r)}(n;rk-2k+2,k)$ exists for all $r\ge 3$ and $k\ge…

Model-Free Deep Hedging with Transaction Costs and Light Data Requirements
Option pricing theory, such as the Black and Scholes (1973) model, provides an explicit solution to construct a strategy that perfectly hedges an option in a continuous-time setting. In practice, however, trading occurs in discrete time and often involves transaction costs, making the direct application of continuous-time solutions potentially suboptimal. Previous studies, such as those by Buehler et al. (2018), Buehler et al. (2019) and Cao et al. (2019), have shown that deep learning or reinf…

Manufacturing Revolutions: Industrial Policy and Industrialization in South Korea
I study the impact of industrial policies on industrial development by considering an important episode during the East Asian miracle: South Korea's heavy and chemical industry (HCI) drive, 1973--1979. Based on newly assembled data, I use the introduction and termination of industrial policies to study their impacts during and after the intervention period. (1) I reveal that heavy-chemical industrial policies promoted the expansion and dynamic comparative advantage of directly targeted industri…
