Motivated by recent experimental observations th.t carbon nanotubes （CNT） can enter animal cells, h.re we conduct coarse grained molecular dynamics and th.oretical studies of th. intrinsic interaction mech.nisms between CNT＇s and lipid bilayer. Th. results indicate th.t CNT-cell interaction is dominated by van der Waals and h.droph.bic forces, and th.t CNT＇s with.sufficiently small radii can directly pierce th.ough.cell membrane wh.le larger tubes tend to enter cell via a wrapping mech.nism. Th.oretical models are proposed to explain th. observed size effect in transition of entry mech.nisms.

Background:Immune ch.ckpoint inh.bitors (ICIs) are effective in a subset of patients with.metastatic solid tumors. h.wever, th. patients wh. would benefit most from ICIs in biliary tract cancer (BTC) are still controversial.Materials and meth.ds:We molecularly ch.racterized tissues and blood from 32 patients with.metastatic BTC treated with.th. ICI pembrolizumab as second-line th.rapy.Results:All patients h.d microsatellite stable (MSS) type tumors. Th.ee of th. 32 patients ach.eved partial response (PR), with.an objective response rate (ORR) of 9.4% (95% confidence interval [CI], 2.0-25.2) and nine sh.wed stable disease (SD), exh.biting a disease control rate (DCR) of 37.5% (95% CI, 21.1-56.3). For th. 31 patients wh. h.d access to PD-1 ligand 1 (PD-L1) combined positive score (CPS) testing (cut-off value ≥1%), th. ORR was not different between th.se wh. h.d PD-L1-positive (PD-L1+; 1/11, 9.1%) and PDL1-(2/20, 10.0%) tumors ( = 1.000). Th. tumor mutational burden (TMB) of PD-L1+ BTC was comparable to th.t of PD-L1-BTC ( = 0.630). TMB and any exonic somatic mutations were also not predictive of pembrolizumab response. Molecular analysis of blood and tumor samples demonstrated a relatively h.gh.natural killer (NK) cell proportion in th. periph.ral blood before pembrolizumab treatment in patients wh. ach.eved tumor response. Moreover, th. tumors of th.se patients presented h.gh.enrich.ent scores for NK cells, antitumor cytokines, and Th. signatures, and a low enrich.ent score for cancer-associated fibroblasts.Conclusions:Th.s study sh.ws th. molecular ch.racteristics associated with.th. efficacy of pembrolizumab in BTC of th. MSS type.

We calculate th. scattering cross section of an electron with.respect to th. spontaneously produced laser radiation in th. first free-electron laser （FEL） with.quantum-wiggler electrodynamics （QWD）. Th. cross section is 1016 times th. Th.mson cross section, confirming th. result obtained by a previous analysis of th. experimental data. A QWD calculation sh.w th.t spontaneous emission in an FEL using only an electric wiggler can be very strong wh.le amplification th.ough.net stimulated emission is practically negligible.

We derive th. cross section of scattering th.ough.th. th.ee-quantum interaction of an electron with.th. incident laser field, th. emitted ph.ton, and an axial electrostatic field produced by th. magnetic wiggler in th. magnetic wiggler acting as th. sole zeroth.order perturbing classical field in th. first free-electron laser （FEL）. In th. derivation, we apply quantum-wiggler electrodynamics （QWD）. We find th.t th.s scattering predominates th. usual two-quantum scattering. Th. output power of spontaneous free-electron two-quantum Stark emission driven by th. above electrostatic field attenuated by th. th.ee-quantum scattering agrees with.n a factor of 10 with.th. measured power in th. case of th. first FEL.
