This paper investigates the on-chip implementation of a frequency locked loop (FLL) over a VCO that decreases the phase noise and linearizes the transfer function. Implementation of the FLL inside a PLL is also investigated and a possible application is highlighted. Design of a special kind of low noise frequency detector without a reference frequency (frequency-to-voltage converter), which is the

Objective. The aim was to evaluate cognitive impairments, psychiatric symptoms and cerebral blood flow (CBF) patterns in middle-aged and younger old patients with subjective experience of memory deficits. Methods. The CBF was measured by 99m-Tc-HMPAO-SPECT. The study group was heterogeneous with patients fulfilling criteria for dementia (n=13) and patients with mild cognitive impairment (MCI; n= 2
In June 2001 the Shanghai Cooperation Organization or SCO was formally inaugurated. The SCO had as of 2001 as its full members China, Russia, Kakakhstan, Kyrgyzstan, Uzbekistan and Tajikistan. Since that time Mongolia, India, Pakistan and Iran have been accepted as observers. There is speculation that Turkmenistan, following its recent change of regime, may also join the SCO in some way in the nea
