Heterogeneous memory is an emerging concept that uses multiple kinds of memories to balance the contradictions between the performance and cost. Many prior researches have addressed the heterogeneous memory designs, which attracted both researchers and practitioners. However, the main challenge in memory design is that the moving costs between memories cannot be ignored, such that forming an effective data allocation plan is a critical part for reducing total costs. This paper focuses on this issue and proposes an adaptive energy-aware approach that is designed for efficiently generating adaptive data allocation plans in heterogeneous memories. Two crucial variables are considered the condition constraints, including time and energy consumptions. The proposed method is called Smart Data Allocation Model (SDAM), which is supported by our algorithm, Smart Switch Allocation Algorithm (SA2). The experimental results have depicted that our approach is superior to prior developed methods. The likelihood of generating optimal solutions is 80.4% - 90.1%. © 2016 IEEE.

High incidence and destructiveness of forest fire determine the importance of forest fire prediction or early detection. we find that the observation of local weather and human behaviors are the most correlated to forest fire important factors. In this paper, a fuzzy inference and big data analysis algorithm is proposed to assess fire risk and calculated the quantitative potential fire risk. These factors converted to triangular fuzzy numbers are calculated by fuzzification and output fire rating level. The continuous 24-hour weather information, which can reflect the high accurate status of forest environment, is collected by the rechargeable wireless sensor network. The fuzzy reasoning system was evaluated for Nanjing City region, the capital of Jiangsu Province, China. The high possibility of potential forest fires risk can be measured by this algorithm, therefore we need to pay more attention to prevent forest fire condition. © 2017 Elsevier Inc.

Thermodynamic quantities, occupation numbers and their fluctuations of a one-dimensional Bose gas confined by a harmonic potential are studied using different ensemble approaches. Combining number theory methods, a new approach is presented to calculate the occupation numbers of different energy levels in microcanonical ensemble. The visible difference of the ground state occupation number in grand-canonical ensemble and microcanonical ensemble is found to decrease by power law as the number of particles increases. © Indian Academy of Sciences.

Large-scale tetracene-doped anthracene nanowire arrays were prepared, and the doping effects were studied. The high doping concentration up to 10% (molar ratio) has been achieved, attributed to both the unique long-nanowire geometry and the excellent structural compatibility of anthracene and tetracene. The incorporation of long tetracene molecules into the matrix of short anthracene molecules induced an enlarged interlayer thickness, a decreased nanowire thickness, and an expanded nanowire width. The tetracene molecules were homogeneously embedded into the anthracene matrix at low doping concentrations (<1%). The doping became inhomogeneous at high doping concentrations (≥1%). The energy transfer efficiency between anthracene and tetracene is nearly 100% at doping concentrations ≥1%. © 2011 American Chemical Society.

The solubilities of mercaptosuccinic acid in binary solvent mixtures consisting of water. +. methanol; water. +. ethanol; and water. +. acetone were determined by a dynamic method over the temperature from 278.15 to 333.15. K. The solubility data were correlated with the modified Apelblat equation and the semi-empirical Buchowski-Ksiazczak λh equation. The Buchowski-Ksiazczak λh equation can regress the solubility data much better than Apelblat equation. The calculated values are in good agreement with the experimental values. This study provides valuable data for the mercaptosuccinic acid purification by the preferential crystallization procedure. © 2013 Elsevier B.V.

Radially oriented anthracene nanowires and their self-assembled concentric ring arrays were prepared through a facial solvent-evaporation method. The successful growth of anthracene nanowires can be attributed to a combined mechanism of molecular self-assembly facilitated by strong π-π intermolecular interactions together with evaporation-induced capillary flow and fingering instability. Their radial orientation is determined by the capillary flow; their shape (either straight or curved nanowires) is governed by the competition between the capillary and Marangoni convectional flows. The self-assembly of nanowires into large-scale concentric ring arrays can be interpreted in terms of the repeated slipping-and-sticking motions of the contact line. The high-quality crystalline anthracene nanowire arrays exhibit size-dependent fluorescence emission with high-degree anisotropy. © 2011 The Royal Society of Chemistry.

Fuzzy C-means clustering algorithm (FCM) is widely applied to the intrusion detection. To acquire a better division for intrusion data, a new method (DEFCM) presented in the paper which combines FCM and differential evolution algorithm (DE) is found application. As a start, several randomly initiated partitions are optimized by FCM, and then the result is provided to differential evolution algorithm. After that, the combined result is sent to FCM again to adjust the partition and obtain the final answer. The method can improve detection performance effectively. The KDDCUP1999 data set is used in the simulation experiment, and the result proves that the DEFCM algorithm has a comparatively high detection rate in intrusion detection. © (2014) Trans Tech Publications, Switzerland.

With the rapid development of information technology, estimation and prediction by big data have been used widely. However, problems exist in the procedure. Due to the flaws of row data, there is still a gap to the truth. Inaccuracy of risk assessment is caused by objective reasons and subjective ones. The advanced assessments of events lead to discrimination. Moreover, regular competition has been replaced by malicious monopoly. In the situation, the harm to data owner is inevitable. In the article, we tend to list risks in big data processing. Not only the risks do harm to fair market, but also there will be detriments on the national economy as a whole in a long run. Our goal is to design a sound regulatory strategy by analyzing the risks and come up with several regulatory advice. © 2015 IEEE.

Oroxylin A is a flavonoid extracted from the root of Scutellaria baicalensis Georgi. Our previous research demonstrated that oroxylin A have various anti-tumor effects including apoptosis, cell cycle arrest, drug-resistant reversion, and others. This paper explores the mechanism how oroxylin A induce apoptosis by regulating uncoupling protein 2 (UCP2) in human colon cancer cells. We found that the inhibition of UCP2 by UCP2 siRNA significantly increased the sensitivity of cells to drugs, reactive oxygen species (ROS) generation and the opening of mitochondrial permeability transition pore (MPTP) of CaCo-2 cells. We also found that UCP2 inhibition could lead to ROS-mediated MPTP activation. Furthermore, we demonstrated that oroxylin A triggered MPTP-dependent pro-apoptotic protein release from mitochondria to matrix and then induced apoptotic cascade by inhibiting UCP2. Intriguingly, the inhibition of UCP2 by oroxylin A was able to block Bcl-2 translocation to the mitochondria, keeping MPTP at open-state. In conclusion, we have demonstrated that UCP2 plays a key role in mitochondrial apoptotic pathway; UCP2s inhibition by oroxylin A triggers the MPTP opening, and promotes the apoptosis in CaCo-2 cells.

This work studies the effects of an aluminum covering on the performance of cross-like Hall devices. Four different Hall sensor structures of various sizes were designed and fabricated. The sensitivity and offset of the Hall sensors, two key points impacting their performance, were characterized using a self-built measurement system. The work analyzes the influences of the aluminum covering on those two aspects of the performance. The aluminum layer covering mainly leads to an eddy-current effect in an unstable magnetic field and an additional depletion region above the active region. Those two points have influences on the sensitivity and the offset voltage, respectively. The analysis guides the designer whether to choose covering with an aluminum layer the active region of the Hall sensor as a method to reduce the flicker noise and to improve the stability of the Hall sensor. Because Hall devices, as a reference element, always suffer from a large dispersion, improving their stability is a crucial issue.
