Discrete Lanchester attrition models: the case of precautionary surrender
Discrete Lanchester-type attrition models describe many types of antagonistic situations; the preferred interpretation is two fleets of battleships, each trying to sink the other. Such models may be characterised by a bivariate recurrence relation. Here I consider a restricted case in which a fleet that finds itself two or three units behind its opponent immediately surrenders. I present some theoretical and numerical results and suggest lines for further work.

Kann mir jemand aus #Hamburg sagen wo geregelt ist (genaue Verordnung) wie lange Parteipaklate, die auf Fraktionsveranstaltungen hinweisen, nach dem VA-Termin hängen bleiben dürfen?

Randomization-based confidence intervals for the local average treatment effect
We consider the problem of generating confidence intervals in randomized experiments with noncompliance. We show that a refinement of a randomization-based procedure proposed by Imbens and Rosenbaum (2005) has desirable properties. Namely, we show that using a studentized Anderson-Rubin-type statistic as a test statistic yields confidence intervals that are finite-sample exact under treatment effect homogeneity, and remain asymptotically valid for the Local Average Treatment Effect when the tre…

Kitaev Interactions Through an Extended Superexchange Pathway in the jeff = 1/2 Ru3+ Honeycomb Magnet, RuP3SiO11
Magnetic materials are composed of the simple building blocks of magnetic moments on a crystal lattice that interact via short-range magnetic exchange interactions. Yet from these simple building blocks emerges a remarkable diversity of magnetic states. Some of these, such as ferromagnetism, are familiar in our everyday lives, while others reveal the deep quantum mechanical origins of magnetism. A prime example of the latter are quantum spin liquid (QSL) states in which -- unlike in a ferromagn…

ExeGPT: Constraint-Aware Resource Scheduling for LLM Inference
This paper presents ExeGPT, a distributed system designed for constraint-aware LLM inference. ExeGPT finds and runs with an optimal execution schedule to maximize inference throughput while satisfying a given latency constraint. By leveraging the distribution of input and output sequences, it effectively allocates resources and determines optimal execution configurations, including batch sizes and partial tensor parallelism. We also introduce two scheduling strategies based on Round-Robin Alloc…

Cost-benefit analysis of ecosystem modelling to support fisheries management
Mathematical and statistical models underlie many of the world's most important fisheries management decisions. Since the 19th century, difficulty calibrating and fitting such models has been used to justify the selection of simple, stationary, single-species models to aid tactical fisheries management decisions. Whereas these justifications are reasonable, it is imperative that we quantify the value of different levels of model complexity for supporting fisheries management, especially given a…

Embedding Economic Incentives in Social Networks Shape the Diffusion of Digital Technological Innovation
The digital innovation accompanied by explicit economic incentives have fundamentally changed the process of innovation diffusion. As a representative of digital innovation, NFTs provide a decentralized and secure way to authenticate and trade digital assets, offering the potential for new revenue streams in the digital space. However, current researches about NFTs mainly focus on their transaction networks and community culture, leaving the interplay among diffusion dynamics, economic dynamics…

Use of Euler's theorem in the elucidation of economic concepts in goods exchange
Starting from a plausible assumption about the Total Revenue concept, a system of economic agents, that simulates the exchange of goods, is studied. Following a methodology equivalent to that used in the statistical-mechanical determination of the distribution of energies in a physical system, it is shown that the price of the exchanged goods arises naturally, as well as the well-known ``Law of demand". It is also shown that by using Euler's Theorem of homogeneous functions, the conditions emer…

Modelling the galaxy radio continuum from star formation and active galactic nuclei in the Shark semi-analytic model
We present a model of radio continuum emission associated with star formation (SF) and active galactic nuclei (AGN) implemented in the Shark semi-analytic model of galaxy formation. SF emission includes free-free and synchrotron emission, which depend on the free-electron density and the rate of core-collapse supernovae with a minor contribution from supernova remnants, respectively. AGN emission is modelled based on the jet production rate, which depends on the black hole mass, accretion rate …

Robust Advertisement Pricing
We consider the robust pricing problem of an advertising platform that charges a producer for disclosing hard evidence of product quality to a consumer before trading. Multiple equilibria arise since consumer beliefs and producer's contingent advertisement purchases are interdependent. To tackle strategic uncertainty, the platform offers each producer's quality type a menu of disclosure-probability-and-price plans to maximize its revenue guaranteed across all equilibria. The optimal menus offer…
