A Scalable and Resource‐Efficient Pipelined p‐Computer for Probabilistic Ising Machines
Advanced Intelligent Systems, EarlyView.(a) Block diagram of the portfolio optimization problem: given M assets, the goal is to determine the optimal weights w that maximize the expected return (based on the mean historical assets return u), while minimizing the risk, quantified by the assets covariance matrix S.

Generalized Ramsey–Turán density for cliques
Forum of Mathematics, SigmaWe study the generalized Ramsey–Turán function $\mathrm {RT}(n,K_s,K_t,o(n))$ , which is the maximum possible number of copies of $K_s$ in an n-vertex $K_t$ -free graph with independence number $o(n)$ . The case when $s=2$

American Journal of Agricultural Economics, EarlyView.Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

A point on discrete versus continuous state-space Markov chains
Dependence ModelingThis article investigates the effects of discrete marginal distributions on copula-based Markov chains. We establish results on mixing properties and parameter estimation for a copula-based Markov chain model with Bernoulli(pp) marginal distributions ...

Asymptotics of Randomly Stopped Sequences with Independent Increments
The Annals of Probability, 1973 Let $S_n, n = 1, 2, \cdots$, be a sequence of sums of independent, identically distributed random variables $X_i$ such that $P\{X_i > y\}$ is a regularly varying function of $y$ at infinity. Let $N$ be a stopping time for $S_n$ with finite mean. A necessary and sufficient condition is given that $$\lim_{y\rightarrow \infty} P\{S_N > y\}/P\{X_1 > y ...

American Journal of Agricultural Economics, EarlyView.Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

ON THE ASYMPTOTIC INDEPENDENCE FOR DIFFUSION PROCESSES ON RIEMANNIAN MANIFOLDS
Kyushu Journal of Mathematics, 1997 In this paper the exit problem for Brownian motions from small geodesic balls in \(n\geq 2\)-dimensional connected \(C^\infty\)-Riemannian manifolds is considered. The independence of the first exit time and the position for Brownian motion with drift is investigated.

The role of venture‐financed startups in innovation for US agriculture
American Journal of Agricultural Economics, EarlyView.Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.
