(Diamond Foundry) Diamonds created by Diamond Foundry. How to make a diamond Diamonds are made of carbon, the same material found in pencil graphite. In nature, geologists believe diamonds are created over millions of years under intense pressure and temperature in the Earth's mantle, and then regurgitated onto the surface by volcanoes. By contrast, synthetic diamonds are made in a lab. Chemically, natural and synthetic diamonds are almost identical, but they can vary in the trace elements found inside. The two most common techniques for making synthetic diamonds are known as high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD). In HPHT , a carbon seed crystal is placed inside a device called a press with a metal solvent and subjected to immense pressures at temperatures around 1,400 degrees Celsius (about 2,250 degrees Fahrenheit), which melts the metal. The molten metal dissolves the carbon crystal, and it solidifies into a diamond. In CVD , a carbon-hydrogen gas mixture is deposited on a surface layer-by-layer. This process usually takes place at about 800 degrees Celsius (1,470 degrees Fahrenheit). Diamond Foundry's method seems to be a combination of HPHT and CVD, said McManus. It's basically the latter method, but at much higher temperatures, she said. The result are diamonds that are as pure as natural ones, the company claims, But ethically and morally pure as well. 下面的是另外一篇报道: Diamonds are a girl’s best friend, but they don’t grow on trees.

Being happy is a choice by June I have chosen to be happy, even after having shed some (sad) tears from time to time. Most of my friends see only the sunny side of me; a very few saw the cloudy me. You were always like sunshine, butnow I know your heart can be heavy, too. This year, I tried to write some personal greetings to friends and loved ones before Christmas, but eventually I surrendered to e-cards of mass mailing. This gives me a chance to “reply” with more personal touch. A few students and clients remembered me by sending me greetings, for which I am grateful. A few friends sent me year-endletter, to whom I responded with my own version of the letter. All these communications make me busy and happy, but only one email touched my soul. In a moment like this, I believe there must be a life before present, and a life after this. You and I must have be lovers 500 years ago, as a Buddhist wouldsay. How else could we meet during a spring break in the paradise by chance, and became soul mates? It is such a wonderful feeling when two strangers in this big world would become close friends. I do hope to meet you again, someday, in this life. Merry Christmas to you…

The tag KSPACING determines the number of k-points if the KPOINTS file is not present (see Sec. 5.5 ). KSPACING is the smallest allowed spacing between k-points in units of Å . The number of k-points increases when the spacing is decreased. The number of k-points in the direction of the first, second and third reciprocal lattice vector is determined by the equations These values are rounded to the next integer. The generated grid is either centred at the point (e.g. includes the point) ( KGAMMA =.TRUE.) or is shifted away from the point, as usually done for Monkhorst Pack grids ( KGAMMA =.FALSE.)

Per default, the grids include the point. 哪一种方法设置的K点更密:KSPACING or KPOINTS? 可通过查看IBZKPT中k点个数,来看哪一种更密 The three qualities of k-point separation for CASTEP (1/Angstrom) coarse.le..08 medium.le..05 fine.le..04 Please input the quality of Monkhorst-Pack grid (Default is .035) 0.03 Reciprocal lattice parameters 0.84446874 2.56760472 2.41391726 Mesh parameters of Monkhorst-Pack grid 1. “Electronlocalization function” ,电子局域化函数。用来描述以某个位置处的电子为参考,在其附近找到与他同自旋的电子的概率,可以表征这个作为参考的电子的局域化程度,也是一种描述在多电子体系中的电子对概率的方法。 2. 一些公式: :电子局域化函数 0 ≤ ELF ≤1 , ELF=1 对应完全局域化,ELF=1/2,对应类电子气型的成对概率。 :均匀电子气的,自旋密度等于 (r)的局域值 :反映电子局域化的信息 :在r位置,s半径内找到两个同自旋的电子的几率,做Taylor 展开,中括号中的项就是上边的D , 这个值越小,说明在上述区域找到相同自旋的电子的几率越小,那么这个电子的局域性越高。 3. 这个函数是由 AxelD.

INCAR做如下修改: ICHARG =11 #MAGMOM = * * * LELF = T LWAVE = F 其它不变。k-mesh不变 cp scf/* bader/. INCAR做如下修改: ICHARG = 1 #MAGMOM=* * * LAECHG = T LWAVE = F 其他不变。k-mesh不变。 以上两个性质计算中,elf是做非自洽计算的,我的理解是,elf仅仅作为初始电荷密度的数值处理,不需要做自洽计算。而bader需要原子价层电子和内层电子,一般vasp的PAW方法不提供内层电子,所以需要以上一步scf电荷密度做输入,来补全电荷密度。原则上这两个任务设置有问题没? 精度方面,elf计算为了提高精度(图的饱满平滑),需要调高NGX(Y,Z),然后重新做静态自洽计算。这个不必提高k采样密度,保持不变就好。 bader计算说要适当调高NGX(Y,Z),使得总电子数等于实际电子数。这个总电子数是不是为bader分析结果文件ACF.dat的最后一行给出的电荷数? 附-from 上述网站的介绍 Original definition of ELF The electron localization function (ELF) was introduced by Becke and Edgecombe as a simple measure of electron localization in atomic and molecular systems . The original formula is based on the Taylor expansion of the spherically averaged conditional same-spin pair probability density to find an electron close to a same-spin reference electron. The main aspect of this formulation is that thus defined ELF is a property of the same-spin pair density . The same-spin pair probability density P 2 ( r , r' ) is the probability density to simulaneously find two like-spin electrons at positions r and r' . In Hartree-Fock (HF) approximation: P 2 ( r , r' ) = rho( r ) ρ( r' ) − |ρ 1 ( r , r' )|2 The conditional same-spin pair probability density P cond ( r , r' ) is the probability density to find an electron at some position r' if a like-spin reference electron is located with certainty at position r . In Hartree-Fock (HF) approximation: P cond ( r , r' ) = ρ( r' ) − |ρ 1 ( r , r' )|2 ⁄ ρ( r ) with the electron densities ρ( r ) and ρ( r' ), and the σ-spin one-particle density matrix ρ 1 ( r , r' ) of the HF determinant: ρ 1 ( r , r' ) = ∑ i σ ψ i * ( r' )ψ i ( r ) where the summation runs over all occupied σ-spin (i.e. either up or down spin) orbitals ψ i ( r ). The probability density to find a like-spin electron at a distance s from the reference point r can be found by a Taylor expansion of the spherically averaged conditional same-spin probability density P cond ( r , s ) (the spherical average is on a shell of radius s around the reference point r ). The first ( s independent) term of the Taylor expansion vanishes, because the conditional probability density to find two like-spin electrons at the same position r is, as a direct consequence of the Pauli principle, equal to zero. The linear term is dependent on the gradient of the HF Fermi hole at r - thus it vanishes as well. The leading (quadratical) term of the Taylor expansion of the spherically averaged conditional same-spin probability density is : P cond ( r , s ) = 1⁄3 s2 + ... The expression in the brackets is besides a ρ factor proportional to the Fermi hole mobility function of Luken and Culberson and is related to the curvature of the HF Fermi hole at r as shown by Dobson . Becke and Edgecombe associated the localization of an electron with the probability density to find a second like-spin electron near the reference point. The smaller this probability density, i.e. the smaller the expression D( r ) = ∑ i σ | ∇ψ i ( r ) | 2 − ¼ | ∇ρ( r ) | 2 ⁄ ρ( r ) of the quadratic term, the higher localized an electron is. Thus, the Pauli repulsion between two like-spin electrons, described by the smallness of D( r ), is taken as a measure of the electron localization. Using the corresponding factor found for uniform electron gas D h ( r ) Becke and Edgecombe defined ELF as follows: η( r ) = 1 ⁄ with χ BE ( r ) = D( r ) ⁄ D h ( r ) where D h ( r ) = 3/5 (6π2) 2/3 ρ( r ) 5/3 Given by the definition, ELF values are bound between 0 and 1. In the seminal paper of Becke and Edgecombe the ratio χ BE ( r ) was attributed to a dimensionless localization index calibrated with respect to the uniform electron gas as a reference. Nevertheless, it should be mentioned that this reference was chosen arbitrarily (originally, Luken and Culberson had defined a function similar to χ BE ( r ), but instead of a division they preferred a subtraction, again arbitrarily choosing the uniform electron gas as a reference). The only measure of the electron localization, as described by the two authors, is the expression D( r ). However, ELF cannot yield the value of D( r ) - i.e. the actual measure of the electron localization - because it depends, through D h ( r ), on the electron density as well. In this sense, ELF is a relative measure of the electron localization. High ELF values show that at the examined position the electrons are more localized than in a uniform electron gas of the same density. η( r ) = 1⁄2 indicates that the effect of the Pauli repulsion is the same as in the uniform electron gas of the same density. Of course, it cannot be compared with the uniform electron gas with respect to other properties (it is obvious that the electron density gradient in an atom, molecule or solid differs from zero almost everywhere). See also section How to interpret . ELF for density functionals In density functional theory the pair density is not explicitly defined. Thus, the original formulation of ELF derived from the pair density is not applicable. Searching for a possibility to use ELF in density functional calculations, Savin et al. utilized the observation that the Kohn-Sham orbital representation of the Pauli kinetic energy density has the same formal structure as the expression D( r ) of Becke and Edgecombe. The main aspect of Savin's formulation is that thus defined ELF is a property based on the diagonal elements of the one-particle density matrix, i.e. the electron density . In the Kohn-Sham method the kinetic energy of N noninteracting electrons is: T s = ½ ∫ ∑ i N | ∇ψ i ( r ) | 2 dv with the Kohn-Sham orbitals ψ i ( r ). The positive definite kinetic energy density t( r ) = ½ ∑ i N | ∇ψ i ( r ) | 2 is bounded by a minimum value: t( r ) ≥ 1⁄8 | ∇ρ( r ) | 2 ⁄ ρ( r ) when all orbitals are proportional to √ρ (i.e. like in a bosonic system) . The Pauli kinetic energy is the energy due to the redistribution of the electrons in accordance with the Pauli principle. It is the integral of the Pauli kinetic energy density: t P ( r ) = t( r ) − 1⁄8 | ∇ρ( r ) | 2 ⁄ ρ( r ) The Pauli kinetic energy density itself does not resolve the bonding situation. It is the more or less arbitrary division of t P ( r ) by the kinetic energy density of a uniform electron gas of the same electron density (with the Fermi constant c F = 3⁄10 (3π2) 2/3 ) t h ( r ) = c F ρ( r ) 5/3 that yields all the information. For a closed shell system the ratio χ S ( r ) = t P ( r ) ⁄ t h ( r ) is formally identical with the ratio χ BE ( r ) in the HF approximation. This identity holds also for an open shell system, when the kinetic energy densities are computed for the corresponding spin part only. Then also the ELF formulas based on χ BE ( r ) and χ S ( r ) respectively, are identical. In the interpretation of Savin et al. ELF is a measure of the influence of Pauli principle as given by the Pauli kinetic energy density, relative to a uniform electron gas of the same density. Similarly to the original definition, ELF does not mirror t P ( r ). An expression equivalent to χ S ( r ) of Savin et al. was found already 1983 by Deb and Ghosh . Deb and Ghosh were searching for a proper local description of the kinetic energy density. They proposed the following formulation of the kinetic energy density: t( r ) = −¼ ∇2ρ( r ) + 1⁄8 | ∇ρ( r ) | 2 ⁄ ρ( r ) + c F f( r ) ρ( r ) 5/3 The right hand side of the above equation consists, besides the density Laplacian that vanishes by an integration over the whole space, of the full Weizsäcker term 1⁄8 | ∇ρ( r ) | 2 ⁄ ρ( r ) and a modified Thomas-Fermi term with a correction factor f( r ). Substituting for the left hand side the Hartree-Fock expression for the kinetic energy density: t( r ) = ½ ∑ i | ∇ψ i ( r ) | 2 − ¼ ∇2ρ( r ) unveils the correction factor f( r ) of Deb and Ghosh as the ratio χ S ( r ) of Savin. Besides calculating f( r ) for noble gas atoms (revealing the atomic shell structure) Deb and Ghosh did not further exploit this function.
I don’t know, but I agree with what Ralph Waldo Emerson wrote in On Friendship in 1841:” In a friend, what I am looking for is not a mush of concessions, a person who would agree with everything that I say; rather what I’m looking for is a beautiful enemy, a person who will challenge me, who will push me, who will help me in my apprenticeship to the truth.” This is also what I do to my friends: challenge them, push them, as well as help them. So, I will not always say nice things to my true friends, but I can say nice things all the time to those I don’t care...I am lucky enough to have a few friends before whom I can say anything in my heart, without thinking about too much.
Your friend is your needs answered. He is your field which you sow with love and reap with thanksgiving. And he is your board and your fireside. For you come to him with your hunger, and you seek him for peace. When your friend speaks his mind you fear not the "nay" in your own mind, nor do you withhold the "ay." And when he is silent your heart ceases not to listen to his heart; For without words, in friendship, all thoughts, all desires, all expectations are born and shared, with joy that is unacclaimed. When you part from your friend, you grieve not; For that which you love most in him may be clearer in his absence, as the mountain to the climber is clearer from the plain. And let there be no purpose in friendship save the deepening of the spirit. For love that seeks aught but the disclosure of its own mystery is not love but a net cast forth: and only the unprofitable is caught. And let your best be for your friend. If he must know the ebb of your tide, let him know its flood also. For what is your friend that you should seek him with hours to kill? Seek him always with hours to live. For it is his to fill your need, but not your emptiness. And in the sweetness of friendship let there be laughter, and sharing of pleasures. For in the dew of little things the heart finds its morning and is refreshed.

After my seminar at U. Washington last Wed., a friend (and a colleague) told me that I should add a title to each slide. In fact, I had done so for half of my slides, but not to all of them. So, I sat down and revised my ppt for my upcoming semimar at U. Hawaii, which is on Nov. 15th (Thursday). See you there?
For the sake of privacy protection, I have deleted those sentences which are personal enough to leak the author's information. The original post: It was recently explained to me by a professor at XX College that the poem by Robert Frost, The Road Not Taken, was meant to be satirical. He has even been quoted as saying "One stanza of 'The Road Not Taken' was written while I was sitting on a sofa in the middle of England: Was found three or four years later, and I couldn't bear not to finish it. I wasn't thinking about mys elf there, but about a friend who had gone off to war, a person who, whichever road he went, would be sorry he didn't go the other. He was hard on himself that way." That completely made life so much better to hear that. Although I'm sure that whoever decides on the curriculum for American Lit in this country would disagree on this, I really think that when you cover satire in your American Lit. classes from now on, you should tell them this story. It really makes life so much nicer, in a strange, small way. My roommate is reading Socrates (Plato) right now, and she hates it. I don't blame her. Reading Socrates is like sticking your head in a pot of boiling water, and then transferring it to the Potomac. In essence, it is painful. So I told her to read it as satire, and that has made all the difference ; ) My mom asked me if I felt it was better satirically because it really says that you have to make choices and that is the way it is. I said that people always make huge deals about what "the right" decision is in a given situation (not necessarily when it comes to ethics, but just situations where you have to made a decision) ... And, for instance, my decision to ... Those were two decisions that could both be great, and they would probably bring me to two very different places in my life. My calling may have even changed, .... But we can't dwell on one decision as the one that "makes all the difference," because we can't know that. In either case our lives go on. And, unlike literal roads, the other decision doesn't exist once we have chosen a road. Because time is linear, any "going back" would actually still be going forward. And this is why I am glad I ... Because it has helped me to think about things like this o.O Paths cannot be compared. They are just so different. And you cannot see all the consequences of your decisions- even the decision that you made. Because our decisions have such a huge influence on so many different things that I don't think any one decision can be considered to have more of an impact than others. I mean some will obviously be remembered, like Obama becoming president ... But there were so many tiny little decisions made that led up to the large decisions. BTW, I have been taught to live in the present, and to not always live for the future, but to be content where I am. I know this is an important lesson for myself, because so often I sit and think about what the future could be like, when all along I am moving along toward that future, without efforts to live through the present. It's like when you are so excited for the weekend, that you forget to live through the week. Reply from one of her friends: Yeah, I like that explanation of the poem better, I think. That we shouldn't agonize over our decisions and search for "the one right answer" because we will never find it - there is a choice between two good paths, with possibly two completely different endings. But both will lead to a good adventure, ... and we must listen for that. But I agree that it is a bad idea to look back at our life choices and waste our time wondering what our lives would be had we chosen the other path. I mean, it's interesting to speculate a little, but there's a fine line between healthy curiosity and wasting one's time wondering about the past. Reply from another friend: I could not agree with you more on that, you never know what the road not taken would have been like. You never know which road would have made more difference, because you simply cannot compare.

The economic miracle of China in the past 30years 2. The high saving rate of the Chinese public 3. Why China continues to buy U.S. Bond even if itpays so little interest 4. How the Chinese public is funding the prosperityof the State Owned Enterprises (SOEs) 5. How wide spread corruption is making a fewChinese very rich at the expense of the public Since there are no quantitative data given in the article,one cannot determine whether or not these explanations given are the principletruth and reason. But I don’t doubt their basic validity. Don’t mind therhetoric of the article but read it as an eye opener.
When you have trouble with a friend, no matter how upset you are, watch what you say. If you cannot talk about it to this friend, take a long walk and sort it out yourself. If a long walk does not free you from the trouble, go talk to this friend. No matter how upset you are, you have to believe she or he has been your friend for years therefore she or he could not be upsetting you intentionally. It takes guts to confront a friend with your hurt feelings, but it's better this way than shutting the door forever... TS, I am very worried about you. You offered to life me up, but I accidentally drown you.

Once, a friend gave me an idea. Its so interesting that I could not wait for any minute. I went to office by bike, though had written nothing. I enjoyed the night. There are no references for this new program. AFTER VISITING BEIJING LIBERARY, THREE TIMES,I HOLD IT. Two months later, an article (on compass satellite) were sent to a Chinese magazine. The editor said, in phone, it maybe an excellent one if Eight years ago, when I invited him to be a co-author, my friend said: its a item, I know , which belongs you, not for me. Just a little pity!Only can I give you the idea! Thats enough. You are a good writer, am I right? So, you must not feel any sorry about that little case. Who are this (captain) friend of mine? He is a post-70s, from middle China s Henan province. Perhaps, you, my dear reader, had seen his photo in my New year Days blog (100 some days ago). March 10, 2010
