Fulltext Range-box plotting relating to discrete distribution

Mohd Bakri Adam, Babangida Ibrahim Babura, Kathiresan Gopal

MATEMATIKA, 2018;34(2):187-204.

MyJurnal

The box plot has been used for a very long time since 70s in checking the existence
of outliers and the asymmetrical shape of data. The existing box plot is constructed
using five values of statistics calculated from either the discrete or continous data. Many
improvement of box plots have deviated from the elegant and simplier approach of exploratory
data analysis by incorporating many other statistic values resulting the turning
back of the noble philosophy behind the creation of box plot. The modification using
range value with the minimum and maximum values are being incorporated to suit the
need of selected discrete distribution when outliers is not an important criteria anymore.
The new modification of box plot is not based on the asymmetrical shape of distribution
but more on the spreading and partitioning data into range measure. The new propose
name for the box plot with only three values of statistics is called range-box plot.

A safety net: use of pseudonyms in oral nursing history

McLeod M, Francis K

Contemp Nurse, 2007 7 12;25(1-2):104-13.

PMID: 17622994

This paper explores the use of pseudonyms in a historical study that weaves oral testimony throughout the narrative. The research was undertaken to unveil the experiences of Australian Army nurses in Malaya's Communist insurgency (1948-1960). Thirty-three women from the Royal Australian Army Nursing Corps served in this conflict termed the Malayan Emergency, but only four nurses could be located for this study. After almost fifty years of silence the female nursing voice emerged as the informants spoke at interview of their unique personal and military experiences in Malaya. It is acknowledged that assigning the nurse informants pseudonyms, as opposed to using their names, constitutes a significant deviation from the established traditions of oral history. However, it is argued that the use of pseudonyms provided an opportunity for candid disclosure by the nurses on a range of topics whilst keeping the informants safe from adverse public or military scrutiny.

PMID: 33061770 DOI: 10.3897/zookeys.971.56571

For the first time in 21 years, a new genus of cardiochiline braconid wasp, Orientocardiochiles Kang & Long, gen. nov. (type species Orientocardiochiles joeburrowi Kang, sp. nov.), is discovered and described. This genus represents the ninth genus in the Oriental region. Two new species (O. joeburrowi Kang, sp. nov. and O. nigrofasciatus Long, sp. nov.) are described and illustrated, and a key to species of the genus, with detailed images, is added. Diagnostic characters of the new genus are analyzed and compared with several other cardiochiline genera to allow the genus to key out properly using an existing generic treatment. The scientific names validated by this paper and morphological data obtained from this project will be utilized and tested in the upcoming genus-level revision of the subfamily based on combined morphological and molecular data.

Fulltext A triclinic polymorph of tri-cyclo-hexyl-phosphane sulfide: crystal structure and Hirshfeld surface analysis

PMID: 28435705 DOI: 10.1107/S205698901700353X

The title compound, (C6H11)3PS (systematic name: tri-cyclo-hexyl-λ(5)-phosphane-thione), is a triclinic (P-1, Z' = 1) polymorph of the previously reported ortho-rhom-bic form (Pnma, Z' = 1/2) [Kerr et al. (1977 ▸). Can. J. Chem. 55, 3081-3085; Reibenspies et al. (1996 ▸). Z. Kristallogr. 211, 400]. While conformational differences exist between the non-symmetric mol-ecule in the triclinic polymorph, cf. the mirror-symmetric mol-ecule in the ortho-rhom-bic form, these differences are not chemically significant. The major feature of the mol-ecular packing in the triclinic polymorph is the formation of linear chains along the a axis sustained by methine-C-H⋯S(thione) inter-actions. The chains pack with no directional inter-actions between them. The analysis of the Hirshfeld surface for both polymorphs indicates a high degree of similarity, being dominated by H⋯H (ca 90%) and S⋯H/H⋯S contacts.

The dihedral angle between the planes of the two rings is 44.03 (16)°. In the crystal, supra-molecular chains are formed along the c axis mediated by C-H⋯O inter-actions involving methine and methyl H atoms as donors, with the carbonyl O atom accepting both bonds; these pack with no specific inter-molecular inter-actions between them.

Leadership and management in health organisations are essential and frequent topics of discussion among professionals and other staff, who are directly or indirectly involved with the operation of the said organisations. In a hospital setting for example, managers are appointed at different functional or unit levels. Though more often than not, we refer to them as the heads or managers or by any other names, the leadership component might be assumed to be just part but not the most important aspect of their roles.(Copied from article).

Fulltext Optimum Design of PIλDμ Controller for an Automatic Voltage Regulator System Using Combinatorial Test Design

Ahmed BS, Sahib MA, Gambardella LM, Afzal W, Zamli KZ

PLoS One, 2016;11(11):e0166150.

PMID: 27829025 DOI: 10.1371/journal.pone.0166150

Combinatorial test design is a plan of test that aims to reduce the amount of test cases systematically by choosing a subset of the test cases based on the combination of input variables. The subset covers all possible combinations of a given strength and hence tries to match the effectiveness of the exhaustive set. This mechanism of reduction has been used successfully in software testing research with t-way testing (where t indicates the interaction strength of combinations). Potentially, other systems may exhibit many similarities with this approach. Hence, it could form an emerging application in different areas of research due to its usefulness. To this end, more recently it has been applied in a few research areas successfully. In this paper, we explore the applicability of combinatorial test design technique for Fractional Order (FO), Proportional-Integral-Derivative (PID) parameter design controller, named as FOPID, for an automatic voltage regulator (AVR) system. Throughout the paper, we justify this new application theoretically and practically through simulations. In addition, we report on first experiments indicating its practical use in this field. We design different algorithms and adapted other strategies to cover all the combinations with an optimum and effective test set. Our findings indicate that combinatorial test design can find the combinations that lead to optimum design. Besides this, we also found that by increasing the strength of combination, we can approach to the optimum design in a way that with only 4-way combinatorial set, we can get the effectiveness of an exhaustive test set. This significantly reduced the number of tests needed and thus leads to an approach that optimizes design of parameters quickly.

Recursive independent component analysis (ICA)-decomposition of ictal EEG to select the best ictal component for EEG source imaging

Habib MA, Ibrahim F, Mohktar MS, Kamaruzzaman SB, Lim KS

Clin Neurophysiol, 2020 03;131(3):642-654.

PMID: 31978849 DOI: 10.1016/j.clinph.2019.11.058

OBJECTIVE: This study aimed to present a new ictal component selection technique, named as recursive ICA-decomposition for ictal component selection (RIDICS), for potential application in epileptogenic zone localization.

METHODS: The proposed technique decomposes ictal EEG recursively, eliminates a few unwanted components in every recursive cycle, and finally selects the most significant ictal component. Back-projected EEG, regenerated from that component, was used for source estimation. Fifty sets of simulated EEGs and 24 seizures in 8 patients were analyzed. Dipole sources of simulated-EEGs were compared with a known dipole location whereas epileptogenic zones of the seizures were compared with their corresponding sites of successful surgery. The RIDICS technique was compared with a conventional technique.

RESULTS: The RIDICS technique estimated the dipole sources at an average distance of 12.86 mm from the original dipole location, shorter than the distances obtained using the conventional technique. Epileptogenic zones of the patients, determined by the RIDICS technique, were highly concordant with the sites of surgery with a concordance rate of 83.33%.

CONCLUSIONS: Results show that the RIDICS technique can be a promising quantitative technique for ictal component selection.

SIGNIFICANCE: Properly selected ictal component gives good approximation of epileptogenic zone, which eventually leads to successful epilepsy surgery.
