Vectorlike quarks(VLQs)with masses at the TeV-scale have been predicted in many new physics scenarios beyond the Standard Model(SM).Based on a simplified(X,T)doublet model including the exotic vectorlike X quark(VLQ-X)with an electric charge 5/3,we study the production of the VLQ-X decaying into tW at the future Compact Linear Collider(CLIC)with √s=3 TeV including the initial state radiation and beamstrahlung *** focus on the final signals,including same-sign dileptons(electrons or muons),at least one b-tagged jet,and large missing transverse *** performing detailed signal-to-background analyses and detector simulations,we obtain the 2σexclusion capabilities and discovery reaches,respectively,on the mass of the VLQ-Xmx as well as the relevant parameters(Br(X→_(t)W))for mx≥1500GeV and the coupling strength g^(*) for mx≥1500 GeV)for some typical luminosities at the 3 TeV CLIC.

Premature ovarian failure (POF) is a prevalent cause of female infertility. POF features include estrogen hypofunction, amenorrhea, infertility, and high gonadotropin levels. The etiology of POF is genetic diseases, autoimmune diseases, enzyme defects and environmental factors. The development of Regenerative medicine has made stem cell and exosome (EXOs) therapy effective for POF. This review discusses POF stem cell research and development.
