Ruin-dependent bivariate stochastic fluid processes [PDF]

arXiv, 2023
This paper presents a novel model for bivariate stochastic fluid processes that incorporate a ruin-dependent behavioral switch. Unlike typical models that assume a shared underlying process, our model allows each process to operate independently until a ruin event in one triggers a change in the other. We develop a mathematical framework for our model,

An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

FEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

L’intérêt environnemental des ruines urbaines : la présence de l’anthropocène au-delà des patrimoines culturels et naturels

Territoire en Mouvement, 2022
The presence of the ruins questions the very of heritage: they escape the tension between the artificial and the natural that structures it. They are not only the testimony of human actions, but also that of the action of nature on them.

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

FEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Fazer um museu numa ruína moderna

Midas: Museus e Estudos Interdisciplinares, 2015
An architectural project in the realm of museography implies a specific research – a disciplinary one. This research merges eventually on precedent positions in the field of curating, art and architecture. This paper proposes an architectural approach to

Parisian Ruin Probability Of An Integrated Gaussian Risk Model [PDF]

arXiv, 2016
In this paper we investigate the Parisian ruin probability for an integrated Gaussian process. Under certain assumptions, we find the Parisian ruin probability and the classical ruin probability are on the log-scale asymptotically the same. Moreover, for any small interval required by the risk process staying below level zero, the Parisian ruin ...

Minimizing the Probability of Lifetime Exponential Parisian Ruin [PDF]

arXiv, 2021
We find the optimal investment strategy in a Black-Scholes market to minimize the probability of so-called {\it lifetime exponential Parisian ruin}, that is, the probability that wealth exhibits an excursion below zero of an exponentially distributed time before the individual dies.

Crime Against History: Slavery, Race, and the 1776 Report

New Directions for Adult and Continuing Education, EarlyView.
ABSTRACT With the 2025 executive order, “Ending Radical Indoctrination in K‐12 Schooling,” the Trump administration reestablished the 1776 Commission, which produced The 1776 Report. This article argues that this report, which is an unsubtle response to The 1619 Project, reveals how White Christian Nationalists wish to mandate that a hyper‐patriotic ...

The Markham Moor Papilio – A Picturesque Commentary [PDF]

The Open Arts Journal, 2014
This commentary on a little-known yet remarkable structure along the A1, originally built as a roadside petrol station with a canopy in the form of a hyperbolic paraboloid, demonstrates the affinity between the architecture of pavilions on the one hand ...

A unified approach to ruin probabilities with delays for spectrally negative Lévy processes [PDF]

arXiv, 2018
In this paper, we unify two popular approaches for the definition of actuarial ruin with implementation delays, also known as Parisian ruin. Our new definition of ruin includes both deterministic delays and exponentially distributed delays: ruin is declared the first time an excursion in the red zone lasts longer than an implementation delay with a ...
