Nonvolatile bistable memory and Ising machine based on Micro-Electro-Mechanical Systems

We propose nonvolatile binary stable states based on microelectromechanical systems (MEMS). They may be used as MEMS memory, where the bistable memory is the buckling direction of a plate of a capacitor. The binary memory is switched by applying a voltage to the MEMS. Furthermore, we propose an Ising model by making a series of buckled MEMS. It is a great merit of this mechanism that the annealing process is automatically carried out due to the damping effect of the spring. We find a duality relation between the parallel-plate MEMS under constant-voltage condition and the comb-teeth MEMS under constant-charge condition.Comment: 8 pages, 10 figure

A facile coplanar reverse electrowetting-ondielectric configuration for more flexible and integratable force/motion sensing applications

Reverse electrowetting on dielectric (REWOD) has been a reliable approach to harvesting energy from low frequency excitations. Previous studies have looked at applying this technology to power various types of sensors using a twoplate electrode structure. This study aims to use REWOD for direct sensing applications using a single plate coplanar structure. The single electrode structure allows for better versatility in materials and applications, as well as making it easier for transportation

Relationship between dietary patterns and risk factors for cardiovascular disease in patients with type 2 diabetes mellitus: a cross-sectional study

BackgroundWhile some dietary patterns are associated with the incidence of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD), the relationship between dietary pattern and risk factors for CVD in patients with T2DM remains to be clarified. The aim of this study was to identify dietary patterns and investigate the relationship between dietary patterns and potential risk factors for CVD in patients with T2DM.MethodsThe study participants comprised 726 Japanese T2DM outpatients free of history of CVD. Life styles were analyzed using self-reported questionnaires. The relationship between dietary patterns, identified by factor analysis, and potential risk factors for CVD was investigated by linear and logistic regression analyses.ResultsSix dietary patterns were identified by factor analysis. Especially, three dietary patterns were associated with risk factors for CVD. The “Seaweeds, Vegetables, Soy products and Mushrooms” pattern, characterized by high consumption of seaweeds, soy products and mushrooms, was associated with lower use of diabetes medication and healthier lifestyles. The “Noodle and Soup” pattern, characterized by high consumption of noodle and soup was associated with higher body mass index, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase and triglyceride levels. The “Fruit, Dairy products and Sweets” pattern was associated with lower γ-glutamyl transpeptidase levels, blood pressure, albuminuria and brachial-ankle pulse wave velocity.ConclusionsThe findings suggested that dietary patterns correlated with risk factors for CVD in T2DM patients
