A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...

DiGeorge/velocardiofacial syndrome (DGS/VCFS) is a disorder caused by a 22q11.2 deletion mediated by non-allelic homologous recombination (NAHR) between low-copy repeats (LCRs). We have evaluated the role of LCR22 genomic architecture and PRDM9 variants as DGS/VCFS predisposing factors. We applied FISH using fosmid probes on chromatin fibers to analyze the number of tandem repeat blocks in LCR2...

The neurobiological underpinnings of effort-related monetary reward processing of gambling disorder have not been previously studied. To date neuroimaging studies lack in large sample sizes and as a consequence less attention has been given to brain reward processing that could potentially be attributed to comorbid conditions such as depressive mood state. We assessed monetary reward processing...

In many countries the power systems are going to move toward creating a competitive structure for selling and buying electrical energy. These changes and the numerous advantages of the distributed generation units (DGs) in term of their technology enhancement and economical considerations have created more incentives to use these kinds of generators than before. Therefore, it is necessary to st...

W e have had a good and active year here in Duke Physics: research groups are expanding, graduate recruitment was excellent, visibility increased both within and beyond campus, a new colloquium series has brought the department together more often, and we carried out the first phase of a reevaluation of our teaching of introductory physics. In this first section, I’ll touch on general issues th...

Distillers grains with solubles (DGS) and corn gluten feed (CGF) are the major byproducts of ethanol production fed to cattle. Both DGS and CGF can be fed wet or dried with animal performance usually similar when fed as wet or dried products; however, some research results favored the wet products. Cattle diets can contain DGS or CGF as replacements for portions of both concentrates and forages...

This article sets out to summarise the research that has investigated the use of dynamic geometry software (DGS) in the teaching and learning of mathematics. This review is not intended to be exhaustive, rather the re s e a rch is categorised under three main headings: interacting with the software, designing teaching activities and learning to prove. Overall, the research has found that DGS ca...

This paper presents a decentralized control method for distributed generations (DGs) in an islanded direct current (DC) microgrid. In most typical DC microgrids, a decentralized control method is based on a voltage droop control method. However, the grid voltage differs from node to node due to line voltage drop, and hence the power sharing ratio among DGs cannot be matched with as desired valu...

OBJECTIVE In a previous study, we assembled a multidisciplinary Canadian panel and identified 37 International Classification of Diseases-10-Canada Diagnosis Groups (DGs) for which emergency department (ED) management may potentially reduce mortality (emergency-sensitive conditions). Before using these 37 DGs to calculate a hospital standardized mortality ratio (HSMR) specific to emergency care...

Optimal power flow (OPF) study is conducted on a power system to achieve one of the following objectives: cost/loss minimization or available transfer capability (ATC) calculation in a deregulated environment. Distributed generation (DG) is a small source of electric power conversion from nonconventional energy sources and Hybrid DGs which often the most cost-effective and reliable way to produ...
