Shared Values and Normal Families of Meromorphic Functions

AbstractIn this paper, we study the normality of a family of meromorphic functions concerning shared values and prove the following theorem: Let F be a family of meromorphic functions in a domain D, let k≥2 be a positive integer, and let a, b, c be complex numbers such that a≠b. If, for each f∈F, f and f(k) share a and b in D, and the zeros of f(z)−c are of multiplicity ≥k+1, then F is normal in D

Factors associated with one year retention to methadone maintenance treatment program among patients with heroin dependence in China

Abstract Objective The aim of this study was to evaluate the risk factors associated with dropout from Methadone Maintenance Treatment (MMT) clinics within a 1 year follow-up cohort study in China. Methods A data analysis is to explore the adherence of MMT during one year from three hundred and twenty patients with heroin dependence at five clinics (3 in Shanghai, 2 in Kunming) in China. All participants were from the part of China-United States cooperation project entitled “Research about improving the compliance and efficacy of methadone maintenance treatment in China”. Our data analysis includes the patients’ attendance in the 6 months clinical study and the data in another 6 months afterward. The data of patients at baseline were collected with the Addiction Severity Index (ASI) which is a semi-structured questionnaire covering socio-demographic characteristics and drug use history. The one year attendance after recruitment at the clinics and daily dose were abstracted from the MMT clinic register system. The Cox proportional hazards model were used to explore the risk factor of dropout, defined as seven consecutive days without methadone. Results By the end of 1 year of treatment 86 patients still remained in MMT without dropout (87% in Shanghai and 13% patients in Kunming). Over the entire 1-year period the median days of remaining in the program were 84 days (in Shanghai and Kunming were 317 days and 22 days).The factors associated with retention included age (HR = 0.98, 95%C.I.:0.96-0.99, P = 0.0062) and ASI alcohol scores (HR = 5.72, 95%C.I.:1.49-21.92, P = 0.0109) at baseline. Conclusion One year retention of newly recruited patients with heroin dependence was related to age and ASI alcohol scores at baseline. The adherence is poorer for the patients who are young and having more serious alcohol problems.http://deepblue.lib.umich.edu/bitstream/2027.42/109460/1/13011_2013_Article_286.pd

Lacunary series and Q

In this paper, we establish a necessary condition for a kind of lacunary series on the unit ball to be in QK. As a consequence, we prove a necessary and sufficient condition for that QK coincides with the Bloch space. In the case of Qp spaces we show that the condition, which is similar to that obtained by Hu, is also sufficient. This is a generalization of the result of Aulaskari, Xiao and Zhao for Qp spaces on the unit disk

How to Be a Popular Physician on E-Consultation Platforms: from Signaling Theory Perspective

With the rapid advancement of web technologies, e-consultation has become increasingly popular in recent decades. While the sustainable development of e-consultation relies on physicians’ commitment, there is little research studying the mechanism of physicians’ attraction for patients. Based on the signaling theory, this study proposes the notion of dynamic signal to capture more effective information and examine the impact of the dynamic signals sent from physicians and patients on physicians’ e-consultation volume. As an important influencing factor, the moderating effect of disease severity is also examined. The preliminary results reveal an invert U-shape relationship between patients’ review volume and physicians’ e-consultation volume and a positive impact of physicians’ dynamic signals on their e-consultation volume. Moderating effect of disease severity is also partially confirmed. The findings provide theoretical contribution to the e-consultation literature and offer a pragmatic insight to both operators and physicians on e-consultation platforms
