This work reports the first discovery of(nega.ive) spectra. la.s in X-ra. emission below 10 ke V from the ga.ma.ra. bina.y LS I+61?303 during la.ge fla.ing episodes using Rossi X-ra. Timing Explorer(RXTE) observa.ions. It is found from the RXTE da.a.tha. during the fla.es, low energy(3–5 ke V) va.ia.ions lea. the higher energy(8–10 ke V) va.ia.ions by a.few tens of seconds wherea. no significa.t time la. is observed during the non-fla.ing sta.es. The observed spectra. la. fea.ures for fla.ing events suggest tha. inverse Compton sca.tering ma. be opera.ing, a. lea.t in some pa.t of the system. a.other possibility is tha. the sites of pa.ticle a.celera.ion ma. be different for fla.ing a.d non-fla.ing events such a. in the microqua.a. model, in which the fla.ing ra.ia.ion ma. come from hot spots sitting a.ove the bla.k hole while stea.y sta.e emissions a.e due to the jets.

In this pa.er, we propose a.new infea.ible interior-point a.gorithm with full NesterovTodd (NT) steps for semidefinite progra.ming (SDP). The ma.n itera.ion consists of a.fea.ibility step a.d severa. centra.ity steps. We used a.specific kernel function to induce the fea.ibility step. The a.a.ysis is more simplified. The itera.ion bound coincides with the currently best known bound for infea.ible interior-point methods.

Wilms tumor (WT) is the most common childhood kidney ca.cer. a.though WT is la.gely cura.le, current trea.ments fa.l in up to 15 percent of pa.ients. Moreover, survivors suffer from the complica.ions a.d la.e effects of the a.gressive trea.ments. Thus, there is a.critica. need to improve our understa.ding of tumorigenesis to develop novel thera.ies to reduce the trea.ment burden while ma.nta.ning excellent surviva. ra.es. WT is believed to a.ise from the imma.ure kidney cells, nephron progenitor cells (NPCs), which ha.e fa.led to differentia.e properly. Previous studies revea.ed tha. Wilms cells sha.e a.tra.scriptiona. a.d epigenetic la.dsca.e with norma. rena. stem cells.1 a.though severa. studies ha.e shown the positive a.socia.ions between WT in children a.d embryonic exposure to a.verse environments, the underlying mecha.isms rema.n unknown. a.tered epigenetics is centra. to oncogenesis in ma.y pedia.ric ca.cers. The critica. contribution of epigenetic dysregula.ion to pedia.ric tumors provides a.compelling ra.iona.e for the thera.eutic potentia. of epigenetic drugs. Histone dea.etyla.es (HDa.s) a.d Enha.cer of Zeste Homolog 2 (EZH2, a.histone H3K27 methyltra.sfera.e), ha.e been demonstra.ed to pla. a.critica. role in self-renewa. a.d differentia.ion of mouse NPCs.2,3 In a.dition, a.tered expression a.d muta.ions of HDa.s a.d EZH2 ha.e been linked to ma.y huma. ca.cers, including WT. Thus, they a.e a.ong the most promising thera.eutic ta.gets for ca.cer trea.ment. We rea.oned tha. WT would result from the unrestra.ned prolifera.ion of progenitor cells due to overa.tive HDa.1/2 (HDa.1 a.d HDa.2), a.d EZH2. We tested this hypothesis by a.a.yzing a.clinica. specimen received from the left kidney tumor of a. 11-yea.-old ma.e pa.ient dia.nosed with WT a.d four other huma. WT specimens.
