An Explanation of the Interactions between Waves and Electrons: Discussion of Electromagnetic Fields

Weiye Xu
Subjects: Physics >> The Physics of Elementary Particles and Fields

The interactions between waves and electrons are the basis of vacuum tubes and particle accelerators. In order to further understand the interactions, we proposed a new electromagnetic model. In this model, the photon is composed of two elementary particles – ephoton and mphoton, which are the basic particles that form the electric fields and magnetic fields, respectively. There are many ephotons around the electrons and the electrons can absorb the ephotons. The proposed electromagnetic model can well explain the electromagetic phenomena and the interactions between waves and electrons.

A non-Lorentz transformation corresponding to the symmetry of inertial systems as an alternative to the rainbow model.pdf

Subjects: Physics >> Geophysics, Astronomy, and Astrophysics

在Lorentz破缺模型中,通常会讨论彩虹模型,因为彩虹模型可以使粒子的能量具有极限而不是与Lorentz变换相对应的具有无限值,而这在量子引力中被认为是必需的。然而,本文表明,当我们只是坚持时空是均匀的,空间是各向同性的并且所有惯性系统都是等价时,并没有必要将光速限制为常数。并且由于光速的变化,我们可以完全构造惯性系统的坐标变换,使粒子的能量有一个极限,而这与彩虹模型相同。 此外,在最近的论文中,作为超高能量尺度的测试,彩虹模型用于研究伽马射线爆,例如GRB 160509A事件,该事件强烈暗示光速随其能量变化的线性形式。所以我们也分析了这个事件,发现我们的模型和彩虹模型之间存在联系。最后,我们简要讨论了如何在超高能量级的未来粒子实验中验证这两个模型。

等离子体湍流(如太阳风)中体现的(矢端图)螺旋现象和信号(近似)谐振现象并不一定表示线性波动行为。不同环境下等离子体可以有不同的动力学特征,容许存在各种非线性结构。这里讨论在一定时空范围内与线性螺旋波表现类似的有单手性主导的湍动涡模态和呼吸子。前者先通过回顾最近利用扩展磁流体模型统计解特征研究太阳风中的建议得以说明;后者的具体例证还是一个开放的问题,但是我们列举各种来自水波、等离子体和玻色-爱因斯坦凝聚的信息来说明太阳风中应该存在这样的结构。

Tan Zhi-Zhong ; Tan Zhen
Subjects: Physics >> Interdisciplinary Physics and Related Areas of Science and Technology

The unified processing and research of multiple network models are implemented, and a new theoretical breakthrough is made, which sets up two new theorems on evaluating the exact electrical characteristics (potential and resistance) of the complex m×n resistor networks by the Recursion-Transform method with potential parameters (RT-V), applies to a variety of different types of lattice structure with arbitrary boundaries such as the nonregular m×n rectangular networks and the nonregular m×n cylindrical networks. Our research gives the analytical solutions of electrical characteristics of the complex networks (finite, semi-infinite and infinite), which has not been solved before. As applications of the theorems, a series of analytical solutions of potential and resistance of the complex resistor networks are discovered. In particular, three novel mathematical propositions are discovered when comparing the resistance in two resistor networks, and many interesting trigonometric identities are discovered as well.

目的 探讨经颅磁电刺激(TMES)疗法对海仁酸(KA)致颞叶癫痫鼠的疗效。 方法 62只大鼠按照随机数字表法分为预处理组(共32只)和治疗组(共30只),预处理组再分为4个小组,分别给予治疗仪最大电流强度(MCI) 0%,25%,50%,75%的电流刺激,确定本实验条件下的最佳刺激参数。治疗组再分为3个小组,每组10只。2组(癫痫刺激组、癫痫非刺激组)为符合纳入标准的癫痫模型大鼠,刺激组刺激参数为预处理组确定出的最佳刺激参数;非刺激组大鼠刺激前后处理与刺激组相同,但治疗仪无有效的能量输出。第3组对照组为未造模对照大鼠。3组大鼠均给予每天1次,40 min/次,共14 d的刺激。记录并比较3组大鼠行为学、电生理学及组织学变化,以评估TMES疗法对癫痫大鼠的疗效。 结果 50%MCI为最佳刺激强度。癫痫刺激组大鼠癫痫波出现的频率明显低于癫痫非刺激组大鼠[(30.210 ±4.580)次/min vs. (31.380 ± 4.247)次/min],差异有统计学意义(t=3.235,P=0.001)。Timm染色结果提示3组大鼠染色评分差异有统计学意义(F=17.429, P=0.000),癫痫刺激组大鼠海马齿状回的内分子层Timm染色评分较癫痫非刺激组明显减轻,差异有统计学意义(P<0.05)。结论 TMES疗法可通过改善癫痫大鼠海马齿状回内分子层组织学变化程度来影响齿状回神经元环路的形成,进而降低癫痫脑电波的发作频率。

Fast_tracking_moving_object_using_single_pixel_imaging.pdf

Subjects: Physics >> Electromagnetism, Optics, Acoustics, Heat Transfer, Classical Mechanics, and Fluid Dynamics

Successive images of a scene are captured and then further processed to achieve the moving object tracking. However, due to modulation rate limitations of the spatial light modulator in single-pixel imaging (SPI) system, the imaging frame rate cannot meet the high-resolution and real-time requirements for object tracking. In this paper, we demonstrate a fast object tracking technique based on SPI with an ultra-low sampling rate that is independent of imaging. We construct modulation information that satisfies the projection conditions and can transform 2D images into 1D projection curves. The 1D projection curves, which provide the location information of the moving object, can be obtained with high resolution in real-time, and then the tracking of the moving object is realized. A background subtraction technique for tracking moving objects that removes static components from a scene is also proposed. The proposed technique is verified by computational simulations and laboratory experiments. In the laboratory experiments, we demonstrate that the proposed method can be used to track moving objects with less than 0.2% of the measurements established by the Nyquist criterion, and it presents a resolution of 256×256 pixels at ~177 fps. The reported technique accelerates the tracking speed of SPI and provides an efficient strategy for remote sensing and biomedical applications.
