We use the mean-field theory to analyze the ground-state phase diagrams of spin-orbit-coupled mass-imbalanced Fermi gases throughout the BCS-BEC evolution, including both the population-balanced and -imbalanced systems. Our calculations show that the competition between the mass and population imbal…

We demonstrate a harmonic-seeded switchable multiwavelength laser in air driven by intense midinfrared femtosecond laser pulses, in which population inversion occurs at an ultrafast time scale (i.e., less than ?200 fs) owing to direct formation of excited molecular nitrogen ions by strong-field ioni…

We propose a method for optical visualization of the Bose-Hubbard model with two interacting bosons in the form of two-dimensional (2D) optical lattices consisting of optical waveguides, where the waveguides at the diagonal are characterized by different refractive indices than others elsewhere, mod…

Lately google made some changes to their ranking algorithm, in the name of providing more relevant search results for it’s users, on official google blog it is estimated 11.8% search results will be affected by this update, in plain English, almost 12% of google search results are useless or of low quality. They planned and started the update about one year ago, maybe that’s why some of my ranks dropped out of first 10 pages, the good thing is that those keywords promoted by content rich links are not affected, a few of these keywords ranked better than ever, it’s safe to say that old way of link building is doomed.
Now what on earth is plain link building and how do people do it? a lot of marketing companies did and are doing the plain link building, they put your links on websites which only exist for holding links, the content on those sites will never be updated, and most of them are useless, the name of link spamming sites is justified. The latest google update will definitely downgrade most if not all of these sites, the links on those spamming sites won’t work anymore.
Let’s check out a few examples. In the very beginning, I didn’t know better, I started with this keyword, cold shuts, of course with old way of link building, almost all the sites I got link from had too many links, worst yet, those sites had no content at all. In the beginning, the ranking of the keyword in question rise pretty fast, lately the keyword link stayed on the first page for a while, this was the case until google made the change. Now let’s look at another keyword, chain puller , most back links for this keyword are from articles and posts, almost no plain links, now we have really good ranking for this keyword. Now contextual links win the battle, then what? In fact the only thing matters here is content, so if you create great content, your rank will improve over time, since search engines are another kind of readers. You may think there are already too many blogs out there, it’s not true, there will never be too many good blogs, take a look at this blog, sue havens toy , I build it as a hobby and kept adding good or mediocre content, you probably think this site won’t rank a all, much to my surprise that the site actually ranks for quite a few keywords. Now you can see, article marketing with great content is the way to go. Say you’re building your own bogging network, for instance Web Sling Shackle, you will have the power to push any sites up in search engines.
Bottom line is that you should create great content, share the content with people, and put your keywords in the context you’re good to go, this strategy will prevail in short or long term. Persistence and patience are the keys to success, you shouldn’t expect things to improve overnight, be it your business or search rankings, now all we have to do is to give our love for creating and sharing quality content and not to worry about the search results every day. One of the best articles directories is EzineArticle, a new article will be indexed and cached in less than an hour, popular blogs will get your post indexed as soon as you post it, here I am going to show you an article in article directory or on a blog, have a taste of this one, Traffic Cone, quality content, nice presentation, indexed by google, this article is a good example of article marketing.
Last but not least, we have hot social media now, no one can afford to not using them. For wordpress blogs, I recommend twitter tools, then go ahead register a new twitter account and app, configure your twitter tools prpperly, then every new post on your blog will show up in your twitter page, it’s real easy and useful, no one should miss this tool out.

Mutually coupled modes of a pair of active LRC circuits, one with amplification and another with an equivalent amount of attenuation, provide an experimental realization of a wide class of systems where gain and loss mechanisms break the Hermiticity while preserving parity-time PT symmetry. For a va…
