Abstract When and where do states coercively alter their internal demography? We build a theory that predicts under what conditions the demographic “facts on ground” by resettling expelling ethno-national populations. predict that, particular scope conditions, will employ engineering to shore up control over (1) nonnatural frontiers, (2) areas populated ethnic minorities who are co-ethnics with elites in hostile power. then substantiate our predictions using new subnational data from both...

Modern instrumental analytical techniques pervade chemical analyses in the authentication, quality control and research wines. A potential alternative approach that does not involve use of expensive equipment, though dependent on availability suitable receptors, is array sensing. 3 × sensing ensembles function via indicator displacement assays, are composed previously explored boronic acid receptors indicators, was used for discrimination three organic acids commonly found wine. This array,...

A key challenge to Geomagnetic Disturbance (GMD) studies is the scarcity of severe geomagnetic field data available researchers due its low event occurrence. This study aims address this by first creating realistic "synthetic" that represents fluctuations caused recent GMD events. paper utilizes a machine-learning approach generate synthetic data. Specifically, application and preliminary results modified form generative adversarial network (GAN) create time-series three different severities...

.We introduce an ensemble Markov chain Monte Carlo approach to sampling from a probability density with known likelihood. This method upgrades underlying by allowing of such chains interact via process in which one chain's state is cloned as another's deleted. effective teleportation states can overcome issues metastability the chain, scheme enjoys rapid mixing once modes target have been populated. We derive mean-field limit for evolution ensemble. analyze global and local convergence this...

We propose to monitor the liquid-solid and gas-liquid phase transition of water based on FBG sensors. The naked FBGs packaged temperature sensors are used monitoring at same time in order find its characteristics, including supercooling state strain pressure change introduced by transition. Fourteen arranged a steam boiler transition, inside wall. preliminary experimental results demonstrated here.

This work presents results on the dynamic modeling and analysis of cascading failures in large-scale electric grids. In this study, outages are simulated using a 2000-bus synthetic grid with detailed generator dynamics, protection systems other system elements. A selection N -2 contingencies applied to cause an initial disturbance. The sequence events following disturbance recorded discussed. Analytical studies performed two most severe scenarios. Current literature describing evolution...

A porphyrin-containing nanoscale covalent organic polymer (COP) was fabricated from 5,10,15,20-tetra(4-carboxyphenyl)porphyrin (TCPP) and cystamine via an acylation reaction. On the one hand, TCPP can induce tumor cell death by laser irradiation. Due to presence of disulfide bonds which react with glutathione, it exhibits depletion glutathione accumulation peroxides in cells. Ultimately hyaluronic acid encapsulate COP get S-COP@HA, nanoparticle a size 168.6 nm also good biosafety....

In this study, hollow mesoporous silica nanoparticles (HMSN) coated with a 4T1 tumor cell membrane were used to construct biomimetic nanomaterials (DTX@CHMSN) for the treatment of breast cancer. The nanodrug can improve water solubility polyenetaxel (DTX) by taking advantage special structure, good biocompatibility, and adjustable surface chemical properties HMSN. Hollow are membranes derived from homologous tumors (CHMSN). Adhesion glycoproteins on cancer specifically bind receptors same...

Solar activity can cause geomagnetic disturbances (GMDs) that give rise to geomagnetically induced currents (GICs) which may compromise the reliability of electric grid.In order build more reliable models representing GMD interactions with power grid, system's detailed electrical model must be considered along fluctuations in earth's magnetic and surface fields. This study investigates impact incorporating spatially varying fields into field on risk metrics. A independent a are compared...

Measuring the changes to earth's magnetic field during geomagnetic disturbance (GMD) events provides valuable insights which can be used better understand potential impacts of GMDs on electrical power grid and develop mitigating measures. This paper analyzes variations in measurement data captured from 17 magnetometers placed across United States over course a strong GMD event that occurred early November 2021. Various correlation analyses are performed based measurements time-shifted...

K-means is a method of vector quantization, which now popularly used for clustering analysis in massive data mining. Due to its heavily computational-intensive feature iteratively re-computing and sorting distances, the execution k-means takes huge amount time, especially when processing large graph such as practical social networks. This paper studies an alternative emulate k-clustering from another view, vertices are partitioned into k farthest clusters. can be implementable...

Then gas-solid two-phase k-∊ turbulent selected Euler-Lagrange method used simulating computation. results show that has stable performance, uniform flux, high cooling efficiency, long useful life.

Screen images are a combination of text, graphics and natural images. They extensively appear in such applications as desktop sharing, remote education, video conference, so on. Ideal compression efficiency on screen contents is unaffordable by classic image or coder. This paper proposes new scheme based H.264 Hue-Saturation-Value (HSV) color quantization, which performs quantification prior to regular encoding. The experimental results show that the proposed improves more than 1-2 dB at...

The future technologies should center around the human beings. How to let interact with various state-of-the-art in a straightforward and intuitive way is grand challenge. Currently uses hands world, however, there are so many scenarios that not able use his control multiple devices/equipment at same time, for instance, while busy carrying stuffs, driving or riding bicycle. Oftentimes, people do want voice command either. But humans really good multi-model interactions using body languages,...

With Chinese economy developing rapidly, the pressure put on individuals and number of special family type has been increasing dramatically, mental health problems therefor plaguing an children. Because school plays important role children’s psychological development, social issue above can be solved most effectively in environment. Play therapy, a therapy which is suitable for children, tackle students' cognitive, behavioral when applied at school. We also provide idea how to apply play
