List of utility function

To avoid speedy deletion, so put it temporarily here.

There are many utility functions used in literature. This page is trying to collect all kinds of utility used in the literature.

Most utilities have the elasticity of intertemporal substitution as the relative risk aversion. The one can separate these two parameters come as an attack on risk premium puzzle. This is not an easy one.

Some terms used to identify a utility function.

   * CES (constant elasticity of substitution, or isoelastic) utility
   * Exponential utility
   * Quasilinear utility
   * Homothetic utility
   * Habit formulation affects the utility
   * Epstein & Zin utility: $U_{t}=\left(u_{t}^{1-{\frac {1}{\psi }}}+\beta \left[E_{t}\left(U_{t+1}^{1-\gamma }\right)\right]^{\frac {1-{\frac {1}{\psi }}}{1-\gamma }}\right)^{\frac {1}{1-{\frac {1}{\psi }}}}$ 

Swallow study

Barium swallow shows that when you eating, some stuff will "always" get into your lung.

One image: the barium in the lung:[[1]]

papers mention barium in lung:

• B. Wani, M. Yeola: Aspiration of barium sulphate in swallow study. The Internet Journal of Pulmonary Medicine. 2009 Volume 10 Number 2. DOI: 10.5580/18b9 - See more at: http://archive.ispub.com/journal/the-internet-journal-of-pulmonary-medicine/volume-10-number-2/aspiration-of-barium-sulphate-in-swallow-study.html#sthash.mQD2DgsW.dpuf

VPal

Some people want to delete it quickly, so I put VPal here. By the way, I am not trying to promote it, instead, I am concerned since the people behind VPal are not identified.

Some Chinese invented a new digital currency VBC. It was said it is based on ripple's RTXP, they change its name to VTXP.

Compared to XRP, VBC is much more popular. At present VBC/USD=80 (from [[2]]), and VBC/CNY=500 (from [3]).

At present, the problem with vpal is that the executives are not public identified. There is no way to find out who is running vpalsystem.com, vpallab.com, vpaltrade.com, and vpalwallet.com, not to mention where they are. People should be concerned whether it is a scam.

Thank you for your edit to the disambiguation page Scale. However, please note that disambiguation pages are not articles; rather, they are meant to help readers find a specific article quickly and easily. From the disambiguation dos and don'ts, you should:

• Only list articles that readers might reasonably be looking for
• Use short sentence fragment descriptions, with no punctuation at the end
• Use exactly one navigable link ("blue link") in each entry
  • Only add a "red link" if used in existing articles, and include a "blue link" to an appropriate article
• Do not pipe links (unless style requires it) – keep the full title of the article visible
• Do not insert external links or references

Thank you. JohnBlackburne^words_deeds 08:56, 27 July 2017 (UTC)

Your comment at Talk:Finite field

Your comment at Talk:Finite field has generated some confusion; it would be helpful if you could weigh in and clarify. Thanks, JBL (talk) 18:43, 10 October 2018 (UTC)

Thanks for coming back. To be honest, I'm not sure why my colleagues are so confused by what you're saying, I think it is clear enough. But they are right about one point, which is that really the field extensions of a prime field (like you are describing) completely exhaust all the finite fields. That is, suppose that I have in my pocket some construction of a field with 25 elements that is different from your construction. (Maybe I start by taking s to be a solution of s^2 = 3, or something.) Then the theorem described in the section Existence and Uniqueness is that our two fields have exactly the same structure: there will be some one-to-one correspondence between the elements of our fields that respects all the field operations. (This is what "isomorphism" means.) Similarly, if I construct a field of order 5^6 in some way different from the way you described, my field will be isomorphic to yours. In particular, if you have a construction that generates finite fields of order p^n for every prime p and positive integer n, then your construction generates every possible finite field (except for the relabelings of the elements).

I hope this is helpful; if not, I am happy to continue the conversation (but maybe here or on my talk page, not on article talk). --JBL (talk) 21:40, 23 October 2018 (UTC)

I agree with what you said. They are all finite "fields", so they are all isomorphic w.r.t the basic properties. then shouldn't the article Finite Field starts with something much simpler one? Should we allow Galois Fields to represent all Finite Fields? Jackzhp (talk) 02:04, 24 October 2018 (UTC)

Leave (film) moved to draftspace

An article you recently created, Leave (film), does not have enough sources and citations as written to remain published. It needs more citations from reliable, independent sources. (?) Information that can't be referenced should be removed (verifiability is of central importance on Wikipedia). I've moved your draft to draftspace (with a prefix of "Draft:" before the article title) where you can incubate the article with minimal disruption. When you feel the article meets Wikipedia's general notability guideline and thus is ready for mainspace, please click on the "Submit your draft for review!" button at the top of the page.

beef might have bacteria which can cause 碳痘病. pork if not well cooked might cause旋毛虫病。

Your draft article, Draft:Leave (film)

Hello, Jackzhp. It has been over six months since you last edited the Articles for Creation submission or Draft page you started, "Leave".

In accordance with our policy that Wikipedia is not for the indefinite hosting of material deemed unsuitable for the encyclopedia mainspace, the draft has been nominated for deletion. If you plan on working on it further, or editing it to address the issues raised if it was declined, simply and remove the {{db-afc}}, {{db-draft}}, or {{db-g13}} code.

If your submission has already been deleted by the time you get there, and you wish to retrieve it, you can request its undeletion by following the instructions at this link. An administrator will, in most cases, restore the submission so you can continue to work on it.

Thanks for your submission to Wikipedia, and happy editing. JMHamo (talk) 09:09, 23 May 2019 (UTC)

September 2020

Hello, I'm N2e. I noticed that you added or changed content in an article, Ethereum, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. N2e (talk) 14:30, 9 September 2020 (UTC)

I would guess you know a lot about Ethereum, so you should be able to find out the what I said is true or false. I said "For example, 0xdAC17F958D2ee523a2206206994597C13D831ec7 is the contract address for ERC20 USDT." Can you please find out what is the contract address for ERC20 USDT? Jackzhp (talk) 01:50, 9 November 2020 (UTC)

That's not how it generally works on Wikipedia. Anyone can edit, but the need to provide source citations for things you want to add to any Wikipedia article is up to you. Cheers. N2e (talk) 03:55, 9 November 2020 (UTC)
