  • Computable linear orders and products 
    Frolov A.N.; Lempp S.; Ng K.M.; Wu G. (2020)
    © 2020 Cambridge University Press. All rights reserved. We characterize the linear order types with the property that given any countable linear order, is a computable linear order iff is a computable linear order, as ...
  • Downward density of exact degrees 
    Liu J.; Wu G.; Yamaleev M. (2015)
    © 2015, Pleiades Publishing, Ltd. In this paper we study exact d.c.e. degrees, the class of d.c.e. degrees which is strictly between the class of degrees of tops of bubbles and the class of isolated d.c.e. degrees.We show ...
  • Measurements of the superconducting anisotropy in FeSe with a resonance frequency technique 
    Cao R.; Dong J.; Wang Q.; Yang Y.; Zhao C.; Zeng X.; Chareev D.; Vasiliev A.; Wu B.; Wu G. (2019)
    © 2019 Author(s). Utilizing a novel method with the resonance frequency of a LC circuit, we measured the superconducting anisotropy of single crystals of an Fe-based superconductor FeSe with applied magnetic field up to ...
  • Nonexistence of minimal pairs in L[d] 
    Fang C.; Liu J.; Wu G.; Yamaleev M. (2015)
    © Springer International Publishing Switzerland 2015. For a d.c.e. set D with a d.c.e. approximation (Formula presented.), the Lachlan set of D is defined as (Formula presented.). For a d.c.e. degree d, L[d] is defined as ...
  • Observation of orbital ordering and origin of the nematic order in FeSe 
    Cao R.; Hu J.; Dong J.; Zhang J.; Ye X.; Xu Y.; Chareev D.; Vasiliev A.; Wu B.; Zeng X.; Wang Q.; Wu G. (2019)
    © 2019 The Author(s). Published by IOP Publishing Ltd on behalf of the Institute of Physics and Deutsche Physikalische Gesellschaft. In iron-based superconductors the interactions driving the nematic order that breaks the ...
  • On a problem of Ishmukhametov 
    Fang C.; Wu G.; Yamaleev M. (2013)
    Given a d.c.e. degree d, consider the d.c.e. sets in d and the corresponding degrees of their Lachlan sets. Ishmukhametov provided a systematic investigation of such degrees, and proved that for a given d.c.e. degree d > ...
  • The d.r.e wtt-Degrees are Dense 
    Wang S.; Wu G.; Yamaleev M. (2019)
    © 2019, Springer Nature Switzerland AG. We prove in this paper that the d.r.e. wtt-degrees are dense, improving a result of Wu and Yamaleev. Our result is a direct generalization of Ladner and Sasso’s splitting theorem for ...
  • The Kierstead's Conjecture and limitwise monotonic functions 
    Wu G.; Zubkov M. (2018)
    © 2018 Elsevier B.V. In this paper, we prove Kierstead's conjecture for linear orders whose order types are ∑q∈QF(q), where F is an extended 0′-limitwise monotonic function, i.e. F can take value ζ. Linear orders in our ...
