In this paper, we give solutions for the two conjectures on the inverse problem of the Wiener index of peptoids proposed by Goldman et al. We give the first conjecture a positive proof and the second conjecture a negative answer.

This article is composed of two independent opinion pieces about the state integrated, coordinated, open, and networked (ICON) principles (Goldman et al., 2021, https://doi.org/10.1029/2021EO153180; Goldman 2022, https://doi.org/10.1029/2021ea002099) in Tectonophysics discussion on opportunities challenges adopting them. Each piece focuses a different topic: (a) global collaboration, technology...

We consider the execution of portfolio transactions with the aim of minimizing a combination of volatility risk and transaction costs arising from permanent and temporary market impact. For a simple linear cost model, we explicitly construct the efficient frontier in the space of time-dependent liquidation strategies, which have minimum expected cost for a given level of uncertainty. We may the...

There are a number of so-called factorization theorems for rook polynomials that have appeared in the literature. For example, Goldman, Joichi and White [6] showed that for any Ferrers board B = F (b1, b2, . . . , bn), n

This paper documents extending the ELEXIR (Engine for LEXicalized Intent Recognition) system (Geib 2009; Geib and Goldman 2011) with a world model. This is a significant increase in the expressiveness of the plan recognition system and allows a number of additions to the algorithm, most significantly conditioning probabilities for recognized plans on the state of the world during execution. Sin...

The frog sartorius muscle is a model tissue for demonstrating to physiology students the principles underlying both membrane phenomena and hypothesis testing. Myocytes can be impaled with conventional glass microelectrodes to measure membrane voltage (Vm). Further, Vm is observed as extracellular K+ is altered and a K+ channel blocker is added. After the experiment, students examine the underly...

Goldman and Darkes (2004) argued that all three basic alcohol-expectancy factors can be assessed with a brief questionnaire (AEMax), related to the circumplex model of emotion. I argue that negative reinforcement, one of the three basic expectancy factors, is not assessed with the AEMax. Importantly, negative reinforcement is positively related to problem drinking while sedation (the AEMax-fact...
