the qom formation, a series of shales, sandstones and carbonate deposits, is the last transgression of the sea in central iran sedimentary basin. foraminifera are one of the most important and numerous fossil groups present in the qom formation. in this study, the micropaleontology of the qom formation in three measured stratigraphic sections in south and west of tafresh (rakin, band-e-ali nagh...
We set sensitive upper limits to the X-ray emission of four Type Ia supernovae (SNe Ia) using the Chandra X-ray Observatory. SN 2002bo, a normal, although reddened, nearby SN Ia, was observed 9.3 days after explosion. For an absorbed, high temperature bremsstrahlung model the flux limits are 3.2 × 10 ergs cm s (0.5–2 keV band) and 4.1 × 10 ergs cm s (2–10 keV band). Using conservative model ass...
Background and purpose: Inhaling substances are hydrocarbons that are converted to gas at room temperature and enter the lungs through the nose and mouth and then our brain. Neurological and psychiatric effects are reported following inhalation, however, there are few studies about acute effect of inhalant on brain electroencephalogram (EEG). Materials and methods: This observational study wa...
Lysates of HEp-2 cells productively infected with herpes simplex virus yielded two bands on isopycnic centrifugation in CsCl gradients, ranging from 1.2 to 1.6 g/cm(3). One band, designated alpha, had a mean buoyant density of 1.27 g/cm(3) and contained herpes virions. Band beta had a mean density of 1.305 g/cm(3) and contained primarily complement-fixing viral antigens and little or no viral d...
We have studied the function and distribution of the alpha 1 beta 1, alpha 5 beta 1 and alpha 6 beta 1 heterodimers on type-1 astrocytes with antibodies specific for integrin subunits (alpha 1, alpha 5, alpha 6, and beta 1). The alpha 1 beta 1 heterodimer mediates adhesion to laminin and collagen, the alpha 5 beta 1 to fibronectin in an RGD-dependent manner. The alpha 5 beta 1 integrin is found...
An equilateral-triangular shape of three alpha clusters surrounded by excess neutrons is suggested for 14C, based on the molecular-orbit model. It is found that the attractive interaction between an excess neutron and an alpha particle stabilizes the K(pi)=0(+) and 3(-) rotational bands, which demonstrates an equilateral-triangular symmetry. This K(pi)=3(-) band at 3 MeV below the 10Be+alpha th...
Recent functional magnetic resonance imaging (fMRI) studies have shown that functional networks can be extracted even from resting state data, the so called "Resting State independent Networks" (RS-independent-Ns) by applying independent component analysis (ICA). However, compared to fMRI, electroencephalography (EEG) and magnetoencephalography (MEG) have much higher temporal resolution and pro...
When attention is allocated to one visual hemifield, increased alpha power is observed in ipsilateral visual cortex. This has been attributed to synchronization of alpha-band oscillations within cortical regions which reflects inhibitory processing. Recent results, however, indicate that synchronization of alpha oscillations between cortical regions is relevant for transient functional coupling...
Korf, R.E., Multi-player alpha-beta pruning (Research Note), Artificial Intelligence 48 (1991) 99-111. We consider the generalization of minimax search with alpha-beta pruning to non-cooperative, perfect-information games with more than two players. The minimax algorithm was generalized in [2] to the maxn algorithm applied to vectors of n-tuples representing the evaluations for each of the play...
