Structural Characteristics of Pennisetum Americanum (Pearl Millet) Using Scanning Electron and Fluorescence Microscopy
Fluorescence bright field and scanning electron microscopy were used to characterize the structure of selected mature pearl millet caryopses from the World Germplasm Collection. Kernel shape (globose, lanceolate, obovate and hexagonal). kernel endosperm color (while. yellow and grey) and external appearance (color) of the samples were documented for 96 varieties. Color of the pearl millet kernel was due to the combined effects of pigmentation in the pericarp. aleurone and endosperm. as well as the pericarp thickness. White kernels had few pigmented areas. yellow kernels had pigments primarily in the epicarp and endosperm. and brown kernels had pigments in the epicarp. aleurone and endosperm. The majority of white, yellow and brown kernels had a thick pericarp. Purple kernels also had pigments in the epicarp, aleurone and endosperm, but had a thin pericarp. Grey kernels had pigments in the aleurone and endosperm. and had a thin pericarp. The periicarp was different from that found in sorghum in that the epicarp cells could be large, round, multilayered and full of pigments, or flat. single-layered and empty. The seed coat and a leurone layer were similar to those found in sorghum. Phytin and nicotinic acid were present in the germ. B-D-glucans were present in the cell walls in the endosperm
Persistent current formation in a high-temperature Bose-Einstein condensate: an experimental test for c-field theory
Experimental stirring of a toroidally trapped Bose-Einstein condensate at
high temperature generates a disordered array of quantum vortices that decays
via thermal dissipation to form a macroscopic persistent current [T. W. Neely
em et al. arXiv:1204.1102 (2012)]. We perform 3D numerical simulations of the
experimental sequence within the Stochastic Projected Gross-Pitaevskii equation
using ab initio determined reservoir parameters. We find that both damping and
noise are essential for describing the dynamics of the high-temperature Bose
field. The theory gives a quantitative account of the formation of a persistent
current, with no fitted parameters.Comment: v2: 7 pages, 3 figures, new experimental data and numerical

Acceptability of a Parental Early Warning Tool: Outcomes from a Feasibility Study of Parental Home Monitoring and Assessment
Aim: to explore the feasibility and acceptability of a Congenital Heart Assessment Tool (CHAT) as part of a home monitoring programme (HMP) for parents going home with their infant between stage 1 & 2 surgery for complex CHD.
Background: HMPs were developed to encourage early recognition of deterioration in infants at risk of potentially life threatening events between stage 1 & 2. In this study, the HMP was compared with the CHAT, a traffic light system enabling assessment of the infant’s condition through individualised parameters.
Method: A mixed methods approach including: data collected at four time points: at discharge [T0]; 2 weeks after [T1], 8 weeks after [T2] & after stage 2 surgery [T3] using self-report tools, interviews & daily diaries. Parents were recruited between August 2013 & February 2015 & randomised to either Gp A: HMP & CHAT; Gp B: CHAT or Gp C: standard discharge care.
Results: 13 mothers, 4 fathers of 13 infants consented (A =5; B =4; C =4). The time period T0 to T3 ranged from 62-228 days; all infants survived stage 1 & 2 of surgery. The qualitative data set included 38 interviews. Four themes emerged regarding the CHAT: prepared parents for the signs to look for at home; easy to use; increased parental confidence & gave them reassurance to call for advice when something was different. Themes emerging regarding the HMP: parents felt daily wt. were not needed; the scales were ‘a hindrance more than helpful’, SpO2 was more reassuring. Gp C parents described normalisation of going home & recognition that the HMP may have made them more reliant & anxious. Only 2 diaries were completed; CHAT amber triggers (n=7 occasions, no admissions); red triggers & drop in SpO2 (n=1, 1 local hospital readmission); calls to ward staff (n=13); other contact with HCP (n=7) no contacts were cardiac in origin.
Conclusions: The CHAT gave parents confidence regarding changes in their infant’s condition. No early admissions for stage 2 based on trigger of CHAT or HMP
Psychosocial Adjustment and Adaptation in Parents of Infants with Complex Congenital Heart Disease Going Home for the First Time Following First Stage Cardiac Surgery: A Prospective Review
Aim: The study presented here prospectively explored psychosocial adaptation and adjustment (anxiety, depression & confidence) in parents going home for the first time with their infants following first stage cardiac surgery for complex congenital heart disease (CHD). Method: 17 parents (13 mothers, 4 fathers) of infants (n=13) being discharged from a specialist cardiac centre in the UK were recruited into a mixed methods feasibility study, from August 2013 until September 2015. Parents were randomised into either: Group A: home monitoring using weighing scales, an oxygen saturation monitor and a Congenital Heart Assessment Tool (CHAT); Group B: the CHAT tool only, or Group C: standard discharge care. Parents were interviewed at 4 time points: T0 before discharge, T1 2 weeks post discharge, T2 8 weeks post discharge and T3 after stage 2 surgery. Baseline demographic data was collected at T0 and parents completed PHQ9, GAD7 and Maternal Confidence score (MCS) at each interview. Results: A fear response was evident in all interviews at T0; 3 mothers and 1 father displayed signs of post-traumatic stress disorder at T0. Mean GAD7 scores were significantly higher before discharge (T0) compared to T3 (p<0.01, d=0.77). There was no significant difference in scores whilst the parents were at home with their infant (T1, T2). Mean PHQ9 scores were significantly higher at T0 than at T1 (p<0.01, d=1.03); T2 (p<0.05, d=0.87); T3 (p<0.01, d=1.1). Mean MCS were significantly higher at T1 (p<0.01, d=1.1), T2 (p<0.01, d=1.3), T3 (p<0.0005, d=1.6) than at T0. Conclusion: Signs of acute stress disorder: anxiety, depression, shock were evident in all interviews at T0. 4 parents showed signs of PTSD however these symptoms decreased over time as their confidence increased. Despite the small number of families recruited into the study, the results provide an important insight into the psychosocial support that parents require between stage 1 and 2 of their infants’ cardiac surgery

Spherical similarity explorer for comparative case analysis
Comparative Case Analysis (CCA) is an important tool for criminal investigation and crime theory extraction. It analyzes the commonalities and differences between a collection of crime reports in order to understand crime patterns and identify abnormal cases. A big challenge of CCA is the data processing and exploration. Traditional manual approach can no longer cope with the increasing volume and complexity of the data. In this paper we introduce a novel visual analytics system, Spherical Similarity Explorer (SSE) that automates the data processing process and provides interactive visualizations to support the data exploration. We illustrate the use of the system with uses cases that involve real world application data and evaluate the system with criminal intelligence analysts
