Hypogene speleogenesis involves the formation of solution-enlarged permeability structures driven by ascending water acquiring its acidity from deep-seated sources. This process occurs in a wide range geological settings and different lithologies. Although hypogene has received increasing attention last two decades, identification former activity caves remains challenging, unless unambiguous mo...

The purpose of the study was to determine if there was a difference in the perception of aesthetics, by dental specialty, using computer assisted asymmetric alteration of the papilla length in the aesthetic zone with an apical alteration of the contact point of the clinical crowns. Standardized photographs were presented to sixty-five randomly selected dentists from New York University College ...

Despite numerous reports on immune checkpoint inhibitor for the treatment of non-small cell lung cancer (NSCLC), the response rate remains low but durable. Thus cisplatin still plays a major role in the treatment of NSCLC. While there are many mechanisms involved in cisplatin resistance, alteration in metabolic phenotypes with elevated levels of reactive oxygen species (ROS) are found in severa...

The life span of C. elegans can be increased via reduced function of the mitochondria; however, the extent to which mitochondrial alteration in a single, distinct tissue may influence aging in the whole organism remains unknown. We addressed this question by asking whether manipulations to ETC function can modulate aging in a cell-non-autonomous fashion. We report that the alteration of mitocho...

In Mobile Ad hoc Networks congestion control and prevention are demanding because of network node mobility dynamic topology. Congestion occurs primarily due to the large traffic volume in case data flow rate inflow is higher than packets on node. This alteration sending results routing delays low throughput. The Rate a significant concern streaming applications, especially wireless networks. TC...

Introduction: With the recent return of remote sensing evidence for aqueous alteration on Mars in the form of evaporates and other secondary minerals (MERs [e.g., 1] and Mars Express [e.g., 2]), understanding the differences between weathering processes on Mars and Earth becomes imperative. Martian meteorites provide the only available source of detailed geochemical analyses of Martian material...

We have shown previously that different patterns of growth (including classical Gompertzian, exponential, and hyperexponential) can be described based on the Gompertzian difference equation, In G(t+s) = a+b In G(t) [G(t), tumor size at time t; s, constant time interval of a stroboscopic set of tumor size measurements], by the initial or intrinsic growth rate, a, and the exponential rate of grow...

We have shown previously that different patterns of growth (including classical Gompertzian, exponential, and hyperexponential) can be de scribed based on the Gompertzian difference equation, In G(t + s) = a + b In G(t) [G(t), tumor size at time t: s, constant time interval of a stroboscopie set of tumor size measurements], by the initial or intrinsic growth rate, a, and the exponential rate of...

In this paper, we aim to achieve two specific objectives. The first one is to examine the applicability of the Artificial Neural Networks (ANNs) technique in ore grade estimation. Different training algorithms and numbers of hidden neurons are applied to estimate Cu grade of borehole data in the hypogene zone of porphyry copper-gold deposit, Masjed-Daghi, East Azerbaijan Province (Iran). The ef...

A nonlinear mathematical model is used to investigate the time evolution of the cell populations in colon crypts (stem, semidifferentiated and fully differentiated cells). To mimic pathological alteration of the biochemical pathways leading to abnormal proliferative activity of the population of semidifferentiated cells their renewal rate is assumed to be dependent on the population size. Then,...
