Probing the primordial Universe using the SKA in combination with other cosmological surveys [PDF]

open access: yes, 2019
>Magister Scientiae - MScNext-generation surveys of the large-scale structure of the Universe will be of great importance in allowing us to extract invaluable information about the nature of the Universe and the physical laws that govern it, at a ...

Presentation: Origins of the Universe

open access: yes, 2001
There have been many ideas and speculation about the age and origin of the Universe. There are four major discoveries that have led us to believe that the universe started in a giant explosion about 13 billion years ago.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

The history of the development of balance in Persian literature [PDF]

open access: yesتاریخ ادبیات, 2009
Establishing a balance between the great world (world) and the small world (man) is one of the common themes of myth, religion, wisdom and mysticism in Iran before and after Islam.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

No-Boundary Wave Functional and Own Mass of the Universe

open access: yesUniverse
An alternative formulation of the no-boundary initial state of the universe in the Euclidean quantum theory of gravity is proposed. Unlike the no-boundary Hartle–Hawking wave function, in which time appears together with macroscopic space–time in the ...

Universal Grammar is a universal grammar

open access: yes, 2014
Language is the most distinctive feature of humans, but there is no consensus on what is characteristic of language. From the point of view of computing, we argue that ‘the human brain circuitry that implements language is Turing complete’. This thesis makes evolutionary sense and natural languages are expressive enough, but two issues against it ...
