Orbits of radial migrators and non-migrators around a spiral arm in N-body simulations [PDF]

open access: yes, 2013
Recent numerical N-body simulations of spiral galaxies have shown that spiral arms in N-body simulations seem to rotate at a similar speed to the local rotation speed of the stellar disc material. This in turn yields winding, transient and recurrent spiral structure, whose co-rotating nature gives rise to changes in the angular momentum (radial ...

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases

open access: yesFEBS Letters, EarlyView.
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Intensification of work-place regimes in British agriculture: the role of migrant workers [PDF]

open access: yes, 2006
In Britain, international migrants have very recently become the major workforce in labour-intensive agriculture. This paper explores the causes of the dramatic increase since the 1990s in the employment of migrant workers in this sub-sector.

Impact of internal migration on population redistribution in Europe: Urbanisation, counterurbanisation or spatial equilibrium? [PDF]

open access: yesComparative Population Studies, [S.l.], v. 44, nov. 2019, 2019
The classical foundations of migration research date from the 1880s with Ravenstein's Laws of migration, which represent the first comparative analyses of internal migration. While his observations remain largely valid, the ensuing century has seen considerable progress in data collection practices and methods of analysis, which in turn has permitted ...

Unconventional mRNA processing and degradation pathways for the polycistronic yrzI (spyTA) mRNA in Bacillus subtilis

open access: yesFEBS Letters, EarlyView.
The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

The Migration Machine

open access: yes, 2011
Anyone travelling to Europe these days comes across not only barriers but also an increasing amount of technology. Bona fide travellers are offered high-tech initiatives (such as iris scans) in the hope that the desire for safety can still be combined with freedom of movement for all citizens.

Migration and Stratification [PDF]

open access: yesSSRN Electronic Journal, 2011
Migration and stratification are increasingly intertwined. One day soon it will be impossible to understand one without the other. Both focus on life chances. Stratification is about differential life chances - who gets what and why - and migration is about improving life chances - getting more of the good things of life.

Efficient Large-Scale Multiple Migration Planning and Scheduling in SDN-enabled Edge Computing [PDF]

open access: yesarXiv, 2021
The containerized services allocated in the mobile edge clouds bring up the opportunity for large-scale and real-time applications to have low latency responses. Meanwhile, live container migration is introduced to support dynamic resource management and users' mobility.

Comments on "Type II migration strikes back -- An old paradigm for planet migration in discs" by Scardoni et al [PDF]

open access: yes, 2020
In the conventional view of type II migration, a giant planet migrates inward in the viscous velocity of the accretion disc in the so-call disc-dominate case. Recent hydrodynamic simulations, however, showed that planets migrate with velocities much faster than the viscous one in massive discs.

The power of microRNA regulation—insights into immunity and metabolism

open access: yesFEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
