This paper presents an impedance compression network (ICN) design in a wireless power transfer (WPT) system to compensate for distance or alignment variations between coils. In midrange WPT applications, magnetic resonant coupling coils are mainly implemented to achieve high efficiency for charging batteries. However, a distance or horizontal alignment variation between coils changes their coupling coefficient, and it decreases the overall performance of WPT systems because the zero voltage switching in a resonant inverter is lost. In order to reduce coil impedance variation, we propose an ICN that compresses variations in coil impedance. The ICN consists of a resistance compression network and a phase compression network to suppress magnitude and phase variations, respectively, in the coil impedance. Only passive components, such as inductors and capacitors, are used to implement an ICN. [ABSTRACT FROM AUTHOR]

Abstract  The closed model category of exterior spaces, that contains the proper category, is a useful tool for the study of non compact spaces and manifolds. The notion of exterior weak ℕ-S-equivalences is given by exterior maps which induce isomorphisms on the k-th ℕ-exterior homotopy groups for k ∈ S, where S is a set of non negative integers. The category of exterior spaces with a base ray localized by exterior weak ℕ-S-equivalences is called the category of exterior ℕ-S-types. The existence of closed model structures in the category of exterior spaces permits to establish equivalences between homotopy categories obtained by dividing by exterior homotopy relations, and categories of fractions (localized categories) given by the inversion of classes of week equivalences. The family of neighbourhoods ‘at infinity’ of an exterior space can be interpreted as a global prospace and under the condition of first countable at infinity we can consider a global tower instead of a prospace. The objective of this paper is to use localized categories to find the connection between S-types of exterior spaces and S-types of global towers of spaces. The main result of this paper establishes an equivalence between the category of S-types of rayed first countable exterior spaces and the category of S-types of global towers of pointed spaces. As a consequence of this result, categories of global towers of algebraic models localized up to weak equivalences can be used to give some algebraic models of S-types. [ABSTRACT FROM AUTHOR]

Objective To assess weight change when once-daily insulin detemir (detemir) or neutral protamine Hagedorn insulin (NPH) are used in already overweight Type 2 diabetes patients requiring intensified insulin therapy. Research design and methods This 26-week randomized, controlled trial included adults with Type 2 diabetes [glycated haemoglobin (HbA1c) 7.5–11.0%, body mass index (BMI) 25–40 kg/m2] who had received two daily doses of insulin (at least one a premix) for ≥ 3 months. Subjects received either detemir ( n = 125) or NPH ( n = 146) once daily in the evening and insulin aspart at main meals. Concomitant treatment with metformin was allowed. Basal insulin was titrated to a pre-breakfast plasma glucose target of 6.1 mmol/l without unacceptable hypoglycaemia. Insulin aspart was also titrated (target, postprandial glucose ≤ 10.0 mmol/l without unacceptable hypoglycaemia). Results At 26 weeks, weight had increased significantly less with detemir (0.4 kg) than with NPH (1.9 kg; difference 1.5 kg, P < 0.0001). BMI increase was also less with detemir than with NPH (difference 0.6 kg/m2, P < 0.0001). HbA1c decreased from 8.9 to 7.8% (detemir) and from 8.8 to 7.8% (NPH; not significant for between-treatment difference). Incidence of hypoglycaemia was lower with detemir [relative risks 0.62 (all events) and 0.43 (nocturnal); P < 0.0001 for both]. Conclusions PREDICTIVE™ BMI was the first study to examine the effect of once-daily detemir with weight as the primary endpoint in a large population of overweight Type 2 diabetes patients. Use of once-daily detemir for intensification of insulin therapy resulted in less weight gain, less hypoglycaemia and equivalent glycaemic control compared with NPH. [ABSTRACT FROM AUTHOR]

Objective: The present study aimed to determine whether the combined effects of environmental estrogens measured as the total effective xenoestrogen burden (TEXB-alpha) are a risk factor for breast cancer over and above the risk potentially linked to specific pesticides. [ABSTRACT FROM AUTHOR]
