– Stimulated by recent experimental results, we simulate " temperature "-cycling experiments in a model for the compaction of granular media. We report on the existence of two types of memory effects: short-term dependence on the history of the sample, and long-term memory for highly compact (aged) systems. A natural interpretation of these results is provided by the analysis of the density het...

This second part of the paper proposes a model for predicting the State-of-Health (SOH) of electrochemical double layers supercapacitors (SCs) during combined high-pulsed power cycling and high-temperature life endurance stresses. The evolutions of the SC capacitance, CSC, during these specific types of stresses have been discussed in part I and, based on the phenomenological observations we ma...

Life time of electronic products is often limited by competing failure mechanisms brought on by the product’s use and its surrounding environment. Solder interconnect failure is a known life limiting failure mechanism that is induced by repeated temperature excursions. Thermal fatigue reliability of solder is conventionally assessed by simple temperature cycling tests, which apply a constant te...

BACKGROUND Daily cycling to work has been shown to improve physical performance and health in men and women. It is very common in the Netherlands: the most recent data show that one quarter of commuting journeys are by bicycle. However, despite the effort going into campaigns to promote commuter cycling, about 30% of commuter journeys up to 5 kilometers are still by car. The question is how to ...

Study selection and analysis: Eligible studies compared people with rapid cycling (>4 mood episodes/year) and non-rapid cycling bipolar disorder; clearly described selection of participants, diagnostic criteria, stated whether rapid cycling was lifetime or current and assessed 18 potential risk factors (reported by at least three studies) associated with rapid cycling. Studies in that only sele...

Photonic structural materials have received intensive interest and have been strongly developed over the past few years for image displays, sensing, and anticounterfeit materials. Their "smartness" arises from their color responsivity to changes of environment, strain, or external fields. Here, we introduce a novel invisible photonic system that reveals encrypted images or characters by simply ...

Chronic myeloid leukemia is a clonal stem cell disorder assoprobe labeled with a different fluorochrome to create a triple-probe/three-color system that permits identification of ciated with the Philadelphia (Ph) translocation [t(9;22) (q34;q11)]. As a result of the Ph translocation, parts of the both the Ph chromosome and the derivative 9 chromosome in Ph cells. This system was used to determi...

Shallow lakes, particularly those in low-lying areas of the subtropics, are highly vulnerable to changes in climate associated with global warming. Many of these lakes are in tropical cyclone strike zones and they experience high inter-seasonal and inter-annual variation in rainfall and runoff. Both of those factors strongly modulate sediment–water column interactions, which play a critical rol...

image retrieval is an important research field which has received great attention in the last decades. in this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. for text-based features, keywords and for content-based features, color and texture features have been used. query in this system contains some keywords and an input...
