the aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. for this purpose, first, an exact mathematical model of phase locked loop (pll) based frequency synthesizer is described and analyzed. then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. based on this formula, the phase ...

The growth toward adulthood occurs mainly through one or several intermediate stages or larval forms. Driven by environmental and internal state cues, all animals undergo one or more transitions during their life, which are accompanied by changes in morphology, physiology, and behavior. Larval settlement in the annelid Platynereis dumerilii is a prime example of such a life-phase transition. In...

The control of spontaneous emission has attracted much attention for many years. For atoms in free space, atomic coherence and quantum interference are the basic phenomena for controlling spontaneous emission [1– 3]; these have potential applications to lasing without inversion [4–10]. Zhu, Scully, and co-workers have studied the quenching of spontaneous emission using an open V-type atom [11],...

results anxiety scores in the intervention groups in active phase after intervention were significantly lower than the control group (p < 0.001). anxiety scores before and after intervention in intervention groups in transitional phase was significantly lower than the control group (p < 0.001). patients and methods this clinical trial study was performed after obtaining informed written consent...

In addition to maintaining consistency of the database, secure concurrency control algorithms must be free from covert channels arising due to data conflicts between transactions. The existing secure concurrency control approaches are unfair to transactions at higher access classes. In this paper, a secure two-phase locking protocol is presented, which is correct and free from covert channels. ...

Sustained cell proliferation requires the duplication and segregation between daughter cells of every cell constituent. Because chromosomes are present in only one or two copies per cell, their duplication and segregation are particularly tightly regulated. To ensure that daughter cells inherit at least one copy of each of their genes and to maintain an appropriate balance in their relative num...
