The Sips isotherm equation, proposed in 1948, is popularly used to describe the adsorption of a diverse array water contaminants by engineered and natural adsorbents. However, that apparent popularity conceals problematic application issues. Our critique its use contaminant research threefold. First, we show linear version equation promoted several reviews bogus. We also highlight problems asso...
The ubiquitin-proteasome system targets numerous cellular proteins for degradation. In addition, modifications by ubiquitin-like proteins as well as proteins containing ubiquitin-interacting and -associated motifs modulate many others. This tightly controlled process involves multiple specific and general enzymes of the system as well as many modifying and ancillary proteins. Thus, it is not su...
the conception and creation of eternal samples is one of the most evident efforts made by man from the very beginning of human life when he observed death and mortality and found all the world's manifestations prone to collapse and destruction. one of the most significant images related to the concept of externality and immortality is circular symbols. in fact, man has represented the conc...
Over the last fifteen years, we have built over a dozen different applications in many domains where the user can define behaviors by demonstration. In some of these, the system uses sophisticated artificial intelligence (AI) algorithms so that complex behavior can be inferred from a few examples. In other systems, the user must provide the full specification, and the examples are primarily use...
We describe a simple model of how a publication’s citations change over time, based on pure-birth stochastic processes with a linear cumulative advantage effect. The model is applied to citation data from the Physical Review corpus provided by APS. Our model reveals that papers fall into three different clusters: papers that have rapid initial citations and ultimately high impact (fast-hi), fas...
