A review of international oil and gas pipeline agreements and its implication in the Iranian legal system [PDF]

open access: yesFaṣlnāmah-i Pizhūhish-i Huqūq-i ̒Umūmī, 2020
Pipelines are one of the most commonly used means for onshore transportation of oil and gas. In general, there are two different approaches which can be used to form the legal framework for the construction and operation of international pipelines: the ...

Matching LTB and FRW spacetimes through a null hypersurface [PDF]

open access: yes, 2007
Matching of a LTB metric representing dust matter to a background FRW universe across a null hypersurface is studied. In general, an unrestricted matching is possible only if the background FRW is flat or open.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

The Use of Unconventional Weapons on the Viewpoints of International Criminal and Islamic Law [PDF]

open access: yesپژوهش تطبیقی حقوق اسلام و غرب, 2015
War crime, as an international criminal act, has many forms which has been criminalized by the international criminal court statute. Some instances of war crime that have been internationally criminalized concern to the use of some kind of  weapons in an

Axisymmetric electrovacuum spacetimes with a translational Killing vector at null infinity

open access: yes, 1999
By using the Bondi-Sachs-van der Burg formalism we analyze the asymptotic properties at null infinity of axisymmetric electrovacuum spacetimes with a translational Killing vector and, in general, an infinite ``cosmic string'' (represented by a conical ...

Current sheet formation and nonideal behavior at three-dimensional magnetic null points [PDF]

open access: yes, 2007
The nature of the evolution of the magnetic field, and of current sheet formation, at three-dimensional (3D) magnetic null points is investigated. A kinematic example is presented which demonstrates that for certain evolutions of a 3D null (specifically ...

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

open access: yesMolecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Quantum Boltzman equation study for the Kondo breakdown quantum critical point

open access: yes, 2009
We develop the quantum Boltzman equation approach for the Kondo breakdown quantum critical point, involved with two bands for conduction electrons and localized fermions. Particularly, the role of vertex corrections in transport is addressed, crucial for

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

open access: yesMolecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.
