Application of Pettis integration to delay second order differential inclusions
In this paper some fixed principle is applied to prove, in a separable Banach space, the existence of solutions for delayed second order differential inclusions with three-point boundary conditions of the form
where is a convex valued multifunction upper semecontinuous on , is a lower semicontinuous multifunction and is a bounded and continuous mapping on . The existence of solutions is obtained under the assumptions that , , where the multifunctions are uniformly Pettis integrable
Corrigendum to Application of Pettis integration to delay second order differential inclusions
This paper serves as a corrigendum to the paper titled Application of Pettis integration to delay second order differential inclusions appearing in EJQTDE no. 88, 2012. We present here a corrected version of Theorem 3.1, because Proposition 2.2 is not true
New type of ellipsometry in infrared spectroscopy: The double-reference method
We have developed a conceptually new type of ellipsometry which allows the
determination of the complex refractive index by simultaneously measuring the
unpolarized normal-incidence reflectivity relative to the vacuum and to another
reference media. From these two quantities the complex optical response can be
directly obtained without Kramers-Kronig transformation. Due to its
transparency and large refractive index over a broad range of the spectrum,
from the far-infrared to the soft ultraviolet region, diamond can be ideally
used as a second reference. The experimental arrangement is rather simple
compared to other ellipsometric techniques.Comment: submitted to Appl. Phys. Let
Mammalian Tissue Response to Low Dose Ionizing Radiation: The Role of Oxidative Metabolism and Intercellular Communication
The objective of the project was to elucidate the mechanisms underlying the biological effects of low dose/low dose rate ionizing radiation in organs/tissues of irradiated mice that differ in their susceptibility to ionizing radiation, and in human cells grown under conditions that mimic the natural in vivo environment. The focus was on the effects of sparsely ionizing cesium-137 gamma rays and the role of oxidative metabolism and intercellular communication in these effects. Four Specific Aims were proposed. The integrated outcome of the experiments performed to investigate these aims has been significant towards developing a scientific basis to more accurately estimate human health risks from exposures to low doses ionizing radiation. By understanding the biochemical and molecular changes induced by low dose radiation, several novel markers associated with mitochondrial functions were identified, which has opened new avenues to investigate metabolic processes that may be affected by such exposure. In particular, a sensitive biomarker that is differentially modulated by low and high dose gamma rays was discovered
