This paper describes a 9-bit 6.2-GHz low power quadrature direct digital synthesizer (DDS) implemented in a 0.18m SiGe BiCMOS technology. With a 9-bit pipeline accumulator and two 8-bit sine-weighted current steering DACs, this DDS is capable of generating quadrature sinusoidal waveforms up to 3.15 GHz with a maximum clock frequency of 6.2 GHz. Packed with more than 13 500 transistors, the quad...

Objective: In this study, we aimed to evaluate the relationship between thiol-disulfide homoeostasis and hemogram parameters in COVID-19 patients.
 Methods: Total thiol(TT), Native thiol(NT), dynamic disulfide status(DDS), DDS/NT, DDS/TT, NT/TT ratio CBC were analyzed 68 patients with positive 31 healthy individuals.
 Results: TT, NT, DD, hemoglobin hematocrit levels higher control gr...

This paper develops methods for Bayesian VAR forecasting when the researcher is uncertain about which variables enter the VAR and the dimension of the VAR may be changing over time. It considers the case where there are N variables which might potentially enter a VAR and the researcher is interested in forecasting N∗ of them. Thus, the researcher is faced with 2N−N ∗ potential VARs. If N is lar...

Due to its simplicity and scalability, the differentiated services (DiffServ) model is expected to be widely deployed across wired and wireless networks. Though DiffServ supporting scheduling algorithms for output-queuing (OQ) switches have been widely studied, there are few DiffServ scheduling algorithms for input-queuing (IQ) switches in the literature. In this paper, we propose two DiffServ ...

Dopamine dysregulation syndrome (DDS) consists of a series of complications such as compulsive use of dopaminergic medications, aggressive or hypomanic behaviors during excessive use, and withdrawal states characterized by dysphoria and anxiety, caused by long-term dopaminergic treatment in patients with Parkinson's disease (PD). Although several ways to manage DDS have been suggested, there ha...

This paper provides an algorithmic pipeline for studying the intrinsic structure of a finite discrete dynamical system (DDS) modelling evolving phenomenon. Here, by we mean, regarding dynamics DDS under observation, feature resulting from ‘cooperation’ two or more smaller DDS. The is described equation over which represents hypothesis phenomenon observation. allows solving such equation, i.e., ...

The OMG Data Distribution Service (DDS), which is a standard specification for data-centric publish/subscribe communications, has shown promise for use in internet of things (IoT) applications because of its loosely coupled and scalable nature, and support for multiple QoS properties, such as reliable and real-time message delivery in dynamic environments. However, the current OMG DDS specifica...
