We present a SUSY model with four Higgs doublets of the"private type,"in which all fermion types(up,down,and charged leptons)obtain their masses from a different Higgs doublet H_f(f=u_1,d,e) .The conditions for anomaly cancellation imply that the remaining Higgs doublet of the model( H_(u_2) )must have the same hypercharge as H_(u_1) ,and thus,can only couple to up-type quarks,which opens the possibility to have FCNCs only in this *** study the lagrangian of the model,and in particular,the Higgs potential,to identify the Higgs mass-eigenstates and their interactions;for the Yukawa matrices,we consider the four-texture *** obtain constraints on the model parameters by using lHC measurements on the properties of the 125 GeV Higgs boson(h),and identify viable regions of the parameter ***,these constraints are used to evaluate the prospects for detecting the FCNC decay mode t→ch at the future high-luminosity(Hl)option for the lHC,which are compared with current limits from ***,we evaluate the FCNC decay of the next heavier Higgs boson H_(2)→tc ,which can typically reach BR(H_2→tc)≈(10^(-4)-10^(-5)) .The search for the signal at Hl-lHC is also studied,and it is found that it may be detectable for specific regions of the model parameter space.

Spine-related disorders are caused by several factors including （1） spinal nerve/visceral nerve stimulation by perivertebral aseptic inflammation, （2） spinal nerve/visceral nerve compression by injured periverterbal soft tissue, dislocated perivertebral small joint, and proliferative/degenerative tissue and, （3） secondary damage to the spinal cord, peripheral nerve, vessels and autonomic nerve, which further stimulate nerve root sheath and surround- ing pain-carrying nerve fibers. In many cases, the source of pain cannot be detected by standard image modalities. Particularly in anatomically complex regions like the spine, SPECT/CT can be helpful for some aspects by intro- ducing a metabolical dimension to the classical way of morphology-based diagnostic. The aim of the present review was to give an overview of the adoption of SPECT/CT in a clinical spine-focused setting.

At the International Geological Congress held in Florence, Italy in August 2004 the IUGS Council approved the formation of a new Commission on Geoscience for Environmental Management. This new Commission was formed to continue IUGS activities in the environment following the closure of the IUGS Commission on Geological Sciences for Environmental Planning(COGEOENVIRONMENT) which had completed its term (refer to separate article in this issue).
