  • How can I calculate the percentage of a phase from X-ray diffraction spectra?

    How can I calculate the percentage of a phases from X-ray diffraction spectra ? Can anyone explain it to me?

    Thanks

    Biruktawit Tarekegne · The University of Tokyo

     Huang Wang, Did you find the way to estimate the phase percentage using JADE software? Any body who knows how to do that?

  • What are the other way than cross validation to set parameters for the training of support vector machine?

    Hello every one i have very few training samples which may not sufficient to set the parameters of support vector machine (c and sigma) through cross validation.

    is there any other method to select the parameters.Also explain the criteria to select the range of regularization parameter and sigma of the Gaussian kernel.

    Revman forest plots - how to add multiple comparisons in one forest plot?

    Hello,

    I have undertook a meta-analysis in Revman 5.3 for the effect of different pollutants on asthma. I am wondering if it is possible to show the different comparisons on one plot rather than separate ones?

    Can anyone please advise?

    Many thanks

    Haneen.

    Are you talking about multiple treatment comparison meta-analysis? Unfortunately, RevMan cannot do that.

  • Rachel Binks added an answer in Molecular Ecology:
    How can I simulate hybrid genotypes from potential parental genetic data? Should I use HybridLab?

    Hi everyone. I've been looking for a software in which I can simulate hybrid crosses between potential parental genotypes. I've found that HybridLab software (Molecular Ecology Notes (2006) 6, 971–973 doi: 10.1111/j.1471-8286.2006.01433.x) could be useful. However the link provided by the authors seems to be broken. Does anyone know where should i go to download this software? Is there any other software I could use?

    Any help will be appreciated :)

    Rachel Binks · Department of Parks and Wildlife (Western Australia)

    I recently had the same problem with the broken link - if you email the author (Einar Nielsen een@aqua.dtu.dk), he'll be able to send you the program. 

  • Eric B. J. Harris added an answer in Silica Gel:
    Please tell the polarity of (petrol/Et2O/Et3N, 74:25:1) in terms of EtOAc/Hexane or MeOH/DCM?

    This is for isolation of a organic compound in Silica gel column chromatography.

    Eric B. J. Harris · Australian National University

    Silica gel chromatography doesn't work that way. Like solubility, polarity is not a single variable that is comparable across all compounds.

    No possible combination of EtOAc/Hexane or MeOH/DCM will have the same properties as Petrol/Et2O/NEt3.

    More generally, Petrol and Hexane have fairly equivalent properties. EtOAc is about twice as polar as Et2O but has similar properties. Chlorinated, aromatic, basic and acidic solvents all introduce their own distinct characteristics and interactions with substrates.

  • Alexander J. Babchin added an answer in Ranking:
    Is there a formal way to distinct a New Effect in Science ?

    The Faraday Induction or Einstein claim that time is not absolute, constituted new effects (or even chapters) in Science. The Mendel laws of genetics is the discovery of comparable rank. 

    But there are many lesser effects in Science, published in journals. Not every reader can realize that text describes the New Effect in Science. So, what are the formal way for this kind of recognition.

    Please, share your personal opinion with your peers. 

    Alexander J. Babchin · Tel Aviv University

    Generally I agree with C.Lewis. But, sometime the author(s) don't realize that his/her results describe the new effect in science, so, he/she does not claim it. In the case they do realize, modesty deter them from such a claim. 

  • Melissa B. Martin asked a question in PAUP:

  • Can Liturgy be an Evangelizing instrument
    I am researching this topic and need input from diverse denominations and Christian groupings.
    Virginia Baldwin Gilbert · Chicago Theological Seminary

    Of course. The movement of contemporary worship was infused with evangelism -- Willow Creek Church, for instance. See this quote from Christianity Today, Nov. 13, 2000 (http://www.christianitytoday.com/ct/2000/november13/5.62.html) about the contemporary liturgical style: 

    "The idea behind all this was to create a new kind of nondenominational church that would use an interesting program and comfortable surroundings to draw in the unchurched. Once drawn in, they would be enveloped in a comprehensive network of activities designed to give them a supportive community and deeper instruction in the Christian faith. This approach was so successful in Chicago that it immediately spawned a host of imitators …"

    Recently the United Methodist Church began new church starts with a contemporary flavor, even to the point of not showing the UMC logo or having "Methodist" in the name of the church. An example is The Gathering, a church featured in this story I wrote for an online news organization:

  • Can anyone help me on formulating the objective function in Genetic Algorithm?
    I am doing optimization using Genetic algorithm on the effect of parameters on the temperature gain in a particular building, that is on the difference between temp without cooling and temp with cooling (temp without cooling - temp with cooling). I am failing to formulate the objective function representing this difference. Please I need help on the objective function having three parameters, i.e.convective heat transfer coefficient, length of storage system, and mass flow rate.
    Thiamhuat Tan · Pepperl-Fuchs Manufacturing Pte Ltd

    you need to know what are the different variables which contribute to your objective functions, for example, 

    objective function f1(x) = A1*x(1) + A2*cos(x2)+ blah + blah

    You would also need to consider the constraint functions.

    After which you need both objective functions and constraints functions and limits of the variables into the GA.

    By the way, which platform of GA are you using? NSGA-II? or just simple GA?

    which software platform are you using? C/C++, etc?

  • Ananda Kafle asked a question in POM:
    How can I see water in a phosphatidylcholine sample under polarizing optical microscope in cross Nicole conditions?

    I frequently find authors claiming the presence of water in a sample by indicating some black spots in POM textures. But such black spots can be possible in many cases of isotropic phases and hence, do not sound convincing enough. Can anybody illustrate this in little more detail ? 

  • Arno Germond added an answer in Smart City:
    Are there actually any "smart cities"?
    "Smart" or "connected cities" are very much of the moment, with large amount of research funds (collaborative and pure), being directed in this area but the activity is often in terms of smaller scale and specific demonstrator projects evidencing aspects of a larger envisaged solution. When do we think we will see true smart cities and what will they look like?
    Arno Germond · RIKEN, Osaka, Japan

    Hi, interesting question indeed.

    As you pointed out, there is first the issue of the definition of "smart city", because it became a trendy work any technological solution or extremely-reduced urban planning solution (for example, a very local neighborhood) is often called "smart". Every mayor is calling its own city smart or connected because it looks good in politics.

    There is however one true example of smart city I know of, a "large-scale" city called MASDAR, you may know about it. There are also the exampled of Hamburg's HafenCity and Tianjin's city in China but I am not fully convinced yet. For me the Masdar project is the most accomplished because, here, being smart is about many aspects within the city. Energy consumption, housing, enterprises, everything is planned. Because it uses only green energy some call this Eco-city, which is for me the "level above" smart cities. However, again, such cities are called Eco-city just because they have a bit of green but a monstrous energy cost anyway. Green NeoCity such as Masdar requires intensive planning efforts and the next step will be probably to create more Eco-cities, and the networks to connect them together.

  • Stanley Kam Sing Wong added an answer in Expertise:
    Is innovation a problem-solving or opportunity-seeking exercise?

    Analysis to paralysis OR time for living dangerously...I am aware that time and circumstances affect perspectives to varying degrees. What has been the verdict in your field of expertise? Some contrasting perspectives in the linked resources may serve to spark this discussion.

    There are many kinds of innovations. Marketing innovation is mainly opportunity-seeking (to find new opportunity for an existing product or to find opportunity to develop a new product to meet the market need). Process innovation is mainly problem-solving (to solve a production problem, quality issue, etc...). R&D innovation and organizational innovation can be both problem-solving or opportunity-seeking.

    Vijay Jayaraman · Jawaharlal Nehru Centre for Advanced Scientific Research

     Thanks for your answer Abram. I didnt know that aspartate can also act as a neurotransmitter. But still, what is the explanation for  glutamate being evolutionarily selected as the major neurotransmitter in the nervous system?

  • Stanley Kam Sing Wong added an answer in Metrics:
    Which alternatives to ROA are most commonly used to measure the economic value?

    The literature on business models usually mentions ROA (return on assets) as the most accepted way of measuring economic value. However, ROA is not a so refined metric compared to contemporary metrics. Despite that, the literature insists on ROA. 

    Companies create value by generating returns on capital. Therefore, ROCE (Return on Capital Employed) is also a widely accepted indicator to compare the relative profitability of companies, especially listed companies.

    Hello, everyone, now I embark on an new research about the relationship on Twitter. However, I was confused how can I map a large amount of links on one map quickly. I have a 250000*250000 0 or 1sparse matrixI which represents the relationship on Twitter. I tried some software like Gephi, but it is too slow to draw the picture on it and it often fail to work. I tried package igraph on R and it runs a whole night and end up with a picture. However, it is very ugly...  Can you give me some advice to deal with it with igraph? or can you recommand some powerful software for me? Thank you very much!

    How to simulate Capacitance-Voltage (CV) characteristics of a Schottky contact using COMSOL?

    Dear Colleagues,

    I am currently trying to validate some CV data. Therefore I would like to model the CV characteristics (capacitance at different bias levels) I am new to COMSOL but it is the only program currently available so I hope there is an easy way to obtain CV results.

    I have already built my 1-D model of the junction but now I am struggling to compute the capacitance.

    Can someone help me out by letting me know which study I can use to calculate the capacitance?

    Do you think the Universal Mind exists?

    I watched the History channel yesterday, and saw the Universal Mind discussed. I can't help wondering what researchers and people in academia think about it. What do you think about the Universal Mind?

    Ravinder Jerath · Augusta Women's Center

    I believe it is a matter of opinion. Based on my theory of unified consciousness which  is based on networking and oscillations in our intra-personal space , all thoughts and sensory information is processed within us.

       In my opinion the idea of universal mind is very beneficial to us as humanity , but its existence can only be proven after we can prove how a human mind truly works.

    Eric B. J. Harris · Australian National University

    Brennan has it right, the easiest method is the addition of aqueous Na2SO3. Avoid Na2S2O3 as under acidic conditions it can precipitate elemental sulfur. Acetone also works but can be somewhat reactive depending on the functional groups of your molecule.
