According to the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), cyst fluid only (CFO) cases are classified in the non-diagnostic category. To date, no large study focusing on CFO has been conducted. To reassess the diagnostic significance of CFO, we compared CFO nodules with non-diagnostic nodules excluding CFO (ND-other). We reviewed the conventional thyroid smears of 715 CFO and...

This paper investigates the impact of CEO and CFO insider purchases on stock returns. The analysis distinguishes between the opportunistic and routine trades made before, during and after the financial crisis of 2007-2008. The results suggest that the informative content of insider trading is weaker than what prior research suggests. The returns on purchases are stronger in the short term and C...

Chloroplast Fo (CF,) was purified from the ATP synthase by Zwittergent 3-12 treatment and DEAE-Trisacryl anion exchange chromatography. Purified CFO contains four subunits corresponding to subunits I, II, III, and IV. CFo mediated proton translocation across the membrane after incorporation into asolectin liposomes. The CFo-mediated proton transport was inhibited by N,N’-dicyclohexylcarbodiimid...

This work presents a novel carrier frequency offset (CFO) estimation algorithm, based on pseudo-CFO (P-CFO), to estimate the CFO value under the conditions of I/Q mismatch for direct conversion structures with 2-dB gain error and 20-deg. phase error in frequency selective fading channels. To circumvent CFO with I/Q mismatch, the proposed P-CFO algorithm rotates three training symbols by adding ...

Multiferroics have broad application prospects in various fields such as multi-layer ceramic capacitors and multifunctional devices owing to their high dielectric constants and coupled magnetic and ferroelectric properties at room temperature. In this study, cobalt ferrite (CFO)/barium calcium titanate (BCT) composite fibers are prepared from BCT and CFO sols by an electrospinning method, and a...

Although elevation of shear stress increases production of vascular reactive oxygen species (ROS), the role of ROS in chronic flow overload (CFO) has not been well investigated. We hypothesize that CFO increases ROS production mediated in part by NADPH oxidase, which leads to endothelial dysfunction. In six swine, CFO in carotid arteries was induced by contralateral ligation for 1 wk. In an add...

CoFe(2)O(4) (CFO)-BiFeO(3) (BFO) nanocomposites are an intriguing option for future memory and logic technologies due to the magnetoelectric properties of the system. However, these nanocomposites form with CFO pillars randomly located within a BFO matrix, making implementation in devices difficult. To overcome this, we present a technique to produce patterned nanocomposites through self-assemb...

The presence of residual carrier frequency offset (CFO) in an orthogonal frequency division multiplexing (OFDM) system leads to a loss of orthogonality between the subcarriers. This introduces inter-subcarrier interference and degrades the system performance significantly. In the literature, Liu and Tureli proposed a blind CFO estimation method based on the observation that in a typical OFDM sy...

BACKGROUND People who have extremely high arched feet or pes cavus often suffer from substantial foot pain. Custom-made foot orthoses (CFO) have been shown to be an effective treatment option, but their specificity is unclear. It is generally thought that one of the primary functions of CFO is redistributing abnormal plantar pressures. This study sought to identify variables associated with pai...

In this paper, we address the problem of carrier frequency offset (CFO) estimation for multipleinput multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. We reconstruct the received signal to form data model with multi-invariance property, and then multiinvariance MUSIC algorithm for CFO estimation is proposed. Our proposed algorithm has the better CFO estimation pe...
