Global strict solutions to continuous coagulation–fragmentation equations with strong fragmentation [PDF]

, 2011
In this paper we give an elementary proof of the unique, global-in-time solvability of the coagulation-(multiple) fragmentation equation with polynomially bounded fragmentation and particle production rates and a bounded coagulation rate.

Habitat Integrity in Protected Areas Threatened by LULC Changes and Fragmentation: A Case Study in Tehran Province, Iran

Land, 2021
The integration and connection of habitats in protected areas (PAs) are essential for the survival of plant and animal species and attaining sustainable development. Investigating the integrity of PAs can be useful in developing connections among patches

The minimum mass for star formation, and the origin of binary brown dwarfs [PDF]

, 2006
Our first aim is to calculate the minimum mass for Primary Fragmentation in a variety of potential star-formation scenarios, i.e. (i) hierarchical fragmentation of a 3-D medium; (ii) one-shot, 2-D fragmentation of a shock-compressed layer; (iii ...

Open Spaces in the European Alps—GIS-Based Analysis and Implications for Spatial Planning from a Transnational Perspective

Land, 2022
This article presents an open space concept of areas that are kept permanently free from buildings, technical infrastructure, and soil sealing. In the European Alps, space is scarce because of the topography; conflicts often arise between competing land ...

Polarized Fragmentation Functions [PDF]

, 1999
In this talk I present a review on the theoretical status of polarized fragmentation functions and the prospects for conceivable future semi-inclusive deep-inelastic scattering and proton-proton collision experiments to measure them.Comment: Talk at the ...

An innovative method to assess specific charge, drilling and blasting costs considering critical factors of rock mass properties, fragment size and blasthole parameters

Results in Engineering
The specific charge has been given as a function of the blastability index (BI) only in previous research, whereas fragment size is one of the attractive blasting results. The impacts of combination of the important factors such as fragment size, in-situ

Fragmentation of the 4He2 dimer with the emission of three or four electrons by fast highly charged projectiles

Frontiers in Physics, 2023
We investigate the fragmentation of the helium dimer, 4He2, into He2+ + He+ and He2+ + He2+ ions in collisions with fast highly charged projectiles. We discuss the main physical mechanisms driving these processes.

Sperm chromatin dispersion test before sperm preparation is predictive of clinical pregnancy in cases of unexplained infertility treated with intrauterine insemination and induction with clomiphene citrate [PDF]

, 2016
Background/aims: A large proportion of men with normal sperm results as analyzed using conventional techniques have fragmented DNA in their spermatozoa.

General Fragmentation Trees

, 2013
We show that the genealogy of any self-similar fragmentation process can be encoded in a compact measured real tree. Under some Malthusian hypotheses, we compute the fractal Hausdorff dimension of this tree through the use of a natural measure on the set

Exploitation of Domestic Ungulate Bones by Bronze Age Pastoralists of the Southern Urals

Археология евразийских степей
The article deals with one of the striking features of the archaeozoological material from the Bronze Age sites in the Southern Urals, which is expressed in the longitudinal fragmentation of livestock bones.
