Magnetic storage, specifically in hard drives has advanced significantly since the first disk drive built in 1956 [1]. Interestingly enough, most of the changes thus far have been realized by scaling the components of a disk drive [1]. In recent years, the superparamagnetic limit has been seen as a possible limit to the rapid increase in hard drive capacities. Antiferromagnetically coupled (AFC...

The areal density of magnetic recording on disc drives has been advancing at a pace in excess of 100% per year in recent years. This has been supported by a continual decrease in media grain size and grain size dispersion and by the use of anti-ferromagnetically coupled (AFC) media. Although it is expected that further gains will be achieved, it is clear that achieving these gains is becoming m...

In this paper, an adaptive fuzzy controller (AFC) for a certain class of unknown nonlinear systems is proposed. The proposed approach employs a fuzzy system to approximate the unknown functions in designing the adaptive controller and an observer is designed to generate an error signal for the adaptive law. The free parameters of the AFC can be tuned on line based on the Lyapunov synthesis appr...

This article deals with the ‘Act of Free Choice’ (AFC/Pepera) whereby Indonesia officially took control West New Guinea under auspices United Nations (UN). The event itself place in 1969 as preordained terms York Agreement August 1962 drawn up by US diplomat, Ellsworth Bunker. In both and AFC, Adam Malik was principal Indonesian participant; both, according to his Report, role UN really no more...

The Tabapuã breed is a beef cattle Brazilian breed known for its sexual precocity and desirable characteristics for tropical conditions. However, this is a newly formed breed and few studies have been conducted regarding genetic parameters and genetic trends for its reproductive traits. The objective of the present study was to estimate the genetic parameters, genetic trends, and relative selec...

OBJECTIVE The aim of this study was to assess which of the basal ovarian reserve markers provides the best reflection of the changes occurring in ovarian function over time (i.e., reproductive aging). DESIGN Prospective longitudinal study. SETTING Healthy volunteers in an academic research center. PATIENT(S) Eighty-one women with normal reproductive performance during the course of their ...

OBJECTIVE This study estimated the genetic parameters for productive and reproductive traits. METHODS The data included production and reproduction records of animals that have calved between 1979 and 2013. The genetic parameters were estimated using multivariate mixed models (DMU) package, fitting univariate and multivariate mixed models with average information restricted maximum likelihood...

The ATP-gated P2X7 receptor (P2X7R) is a non-selective cation channel which senses high extracellular ATP concentrations and has been suggested as a target for the treatment of neuroinflammation and neurodegenerative diseases. The use of P2X7R antagonists may therefore be a viable approach for treating CNS pathologies, including epileptic disorders. Recent studies showed anticonvulsant potentia...

Art For Children (AFC) adalah sebuah program yang bentuk oleh Taman Budaya Yogyakarta. Tercatat sebanyak 7 cabang seni diajarkan di dalamnya, salah satunya ialah teater. Proses kreatif teater pada AFC ini cukup menarik karena tidak menggunakan teks. Penelitian mencoba melihat upaya dilakukan guru selama proses kelas AFC. Peran tersebut hanya tentang otoritas dalam teater, tetapi juga cara memak...
