Effects of the merger history on the merger rate density of primordial black hole binaries
European Physical Journal C: Particles and Fields, 2019 We develop a formalism to calculate the merger rate density of primordial black hole binaries with a general mass function, by taking into account the merger history of primordial black holes.

, 2007 We compare the use of galaxy asymmetry and pair proximity for measuring galaxy merger fractions and rates for a volume limited sample of 3184 galaxies with -21 < M(B) -5 log h < -18 mag.

Predation and mergers: Is merger law counterproductive? [PDF]
European Economic Review, 2004 Abstract This paper extends the literature on predation and mergers to a multi-firm setting. Two new arguments why predation is rational when a merger is an alternative are provided. First, predation is less prone to the free-rider problem, since mergers concentrate the costs of eliminating a rival with one firm, whereas predation allows the costs to

The Slow Merger of Massive Stars: Merger Types and Post-Merger Evolution [PDF]
International Astronomical Union Colloquium, 2002 AbstractWe study the slow merger of two massive stars inside a common envelope. The initial close binary system consists of a massive red supergiant and a main-sequence companion of a few solar masses. The merger product is a massive supergiant with an interior structure (core mass and composition profile) which is significantly different from that of ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Comparative Study of the Legal Tools Superseding Bankruptcy of Banks [PDF]
Faṣlnāmah-i Pizhūhish-i Huqūq-i Khuṣūṣī, 2019 Banks, like any other commercial entity, are likely to encounter the risk of insolvency and consequently go bankrupt for some reasons. As the provisions on bankruptcy are subject to the rules and regulations of the Commercial Code, the solution for ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Numerical simulations of dwarf galaxy merger trees [PDF]
, 2014 We investigate the evolution of dwarf galaxies using N -body/SPH simulations that incorporate their formation histories through merger trees constructed using the ex- tended Press-Schechter formalism.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
