On the Long-range Dependence of Fractional Poisson and Negative Binomial Processes
We study the long-range dependence (LRD) of the increments of the fractional
Poisson process (FPP), the fractional negative binomial process (FNBP) and the
increments of the FNBP. We first point out an error in the proof of Theorem 1
of Biard and Saussereau (2014) and prove that the increments of the FPP has
indeed the short-range dependence (SRD) property, when the fractional index
satisfies . We also establish that the FNBP has
the LRD property, while the increments of the FNBP possesses the SRD property.Comment: 17 page
ASSESSMENT OF COGNITIVE FUNCTION IN PATIENTS WITH CHRONIC KIDNEY DISEASE
Objectives: The objectives of this study were to evaluate cognitive profile in patients with chronic kidney disease (CKD) pre-dialysis and post-dialysis, to assess the severity of cognitive impairment in patients with kidney disease before and after dialysis, and to determine the association of cognitive impairment in relation to dialysis.Methods: A total of 59 patients were recruited with CKD Stage V on dialysis for >6 months. Cognitive function of the patient was assessed by Montreal Cognitive Assessment test scale method for three intervals (before dialysis and two intervals post-dialysis), and the incidence of impairment was analyzed using one-way ANOVA variance test.Results: Among the 59 patients, there were 13 patients with the age of 18–33 years (22.033%), 11 patients with from age 34 to 49 years (18.64%), 21 patients at the age of 50–65 years (35.59%), and 15 patients around 66–80 years (25.42%). From the above categories, population with the age of 50–65 years is at maximum affected by CKD. Among the 59 patients, 24 patients (40.677%) are male and 35 patients (59.33%) are female. There was a mild significant difference seen in cognitive functioning between pre-dialysis and post-dialysis (p≤0.02).Conclusion: It was found that patients with CKD had mild-to-moderate cognitive dysfunction due to morbidities associated with CKD. Inthis study, significant differences of cognitive function result in CKD patients and the severity of cognitive impairment was associatedwith the severity of the kidney disease, which improved with dialysis. Finally, our study suggests that cognitive performance wasimproved after initiation of dialysis and that further management through medications could provide a better outcome in cognitiveperformance
Flux free growth of large FeSe1/2Te1/2 superconducting single crystals by an easy high temperature melt and slow cooling method
We report successful growth of flux free large single crystals of
superconducting FeSe1/2Te1/2 with typical dimensions of up to few cm. The AC
and DC magnetic measurements revealed the superconducting transition
temperature (Tc) value of around 11.5K and the iso-thermal MH showed typical
type-II superconducting behavior. The lower critical field being estimated by
measuring the low field iso-thermal magnetization in superconducting regime is
found to be above 200 Oe at 0K.Comment: 15 pages text + Figs. Novel large cm size FeSe1/2Te1/2

DEVELOPMENT OF RENAL DOSING GUIDELINES FOR NONSTEROIDAL ANTI-INFLAMMATORY DRUGS AND ANTIBIOTICS - A PROSPECTIVE STUDY
Objectives: The objectives of this study were to determine the impact of renal dosing guidelines on prescribing pattern for nonsteroidal anti-inflammatory drugs and antibiotic in patients with chronic kidney disease (CKD).Methods: This was a prospective interventional study. The study was divided into two phases, pre-intervention and post-intervention phases. Data regarding the kidney function and the pattern of drug dosing will record in the pre-intervention phase. Pocket guides were prepared for the drug dosing in renal impairment and were distributed to clinicians and the pharmacist as a part of intervention. In the post-intervention phase, the dosing pattern of renal eliminated drugs was observed for any improvement. The patterns of dosing of renal eliminated drugs were compared in both the phases.Results: In pre-interventional phase, a total of 43 cases were reviewed, 20 of them were non-hemodialysis (non-HD) (9 female and 11 male) cases with a mean±standard deviation (SD) age of 56.05+8.22 (56) and 23 were undergoing HD (11 female and 12 male) cases with a mean±SD age of 56.72+6.85 (56). In the post-intervention phase, a total of 41 cases were reviewed, 22 of them were non-HD (12 female and 10 male) cases with a mean±SD age of 55.85+6.87 (57) and 19 were undergoing HD (10 female and 9 male) cases with a mean±SD age of 55.77+8.39 (56.6).Conclusion: Health-care professionals have an important responsibility in monitoring the dose for renal impairment patients. Development of renal dosing guidelines for patients hospitalized with CKD can improve the pattern of prescribing in renal failure population.Â
