Maximum loss and maximum gain of spectrally negative Levy processes [PDF]
, 2017 The joint distribution of the maximum loss and the maximum gain is obtained for a spectrally negative Lévy process until the passage time of a given level. Their marginal distributions up to an independent exponential time are also provided. The existing

An optimal dividends problem with transaction costs for spectrally negative Lévy processes [PDF]
, 2009 We consider an optimal dividends problem with transaction costs where the reserves are modeled by a spectrally negative Lévy process. We make the connection with the classical de Finetti problem and show in particular that when the Lévy measure has a log-

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...

The Role of Polyphenols in Respiratory and Gut Health: From the Perspective of Gut‐Lung Axis
Phytotherapy Research, EarlyView.ABSTRACT The gut‐lung axis constitutes a dynamic, multidirectional communication platform between the gastrointestinal and respiratory tracts. Its complexity arises from the integrated crosstalk among the microbiota, immune system, and redox homeostasis, collectively influencing disease susceptibility and progression.

Wildlife Biology, EarlyView.Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

A first passage time problem for spectrally positive Lévy processes and its application to a dynamic priority queue [PDF]
, 2013 We study a first passage time problem for a class of spectrally positive Lévy processes. By considering the special case where the Lévy process is a compound Poisson process with negative drift, we obtain the Laplace–Stieltjes transform of the steady ...

Shrub encroachment influences root traits and mycorrhization in subalpine grasslands
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Shrub encroachment into grasslands modifies ecosystem functions, species composition and soil properties. However, knowledge about its detailed below‐ground effects and specifically on concurrent changes in root traits and mycorrhizal associations is missing. We studied

Why do Public Debates Escalate? Trigger Points and the Moral Dynamics of “Hot Politics”
The British Journal of Sociology, EarlyView.ABSTRACT Escalating, emotionally charged, and moralized forms of controversy are a central feature of contemporary politics. Our study develops a framework for understanding how political debates between ordinary citizens become heated; why certain issues provoke particularly strong emotions; and how this affective potential is weaponized by ...

Unequal Family Ties, Wealth Transmission and Social Mobility Among Congolese Traders in Kinshasa
The British Journal of Sociology, EarlyView.ABSTRACT Based on ethnographic fieldwork among Congolese traders operating in Kinshasa's urban economy, this article examines how differentiated family ties and wealth transmission shape social mobility and the intergenerational reproduction of inequality. We show that family support is neither uniform nor equally productive: its effects depend on both
