For our KDP crystal.orientation, various tberm.-optic （TO） and rel.vant tem.erature-dependence param. eters are defined, presented, and studied in the fram.work of a transverse and a l.ngitudinal.el.ctro-optic （EO） m.dul.tion system.. this study is based on the concept of the so-cal.ed opto-el.ctrical.bias （~） ap- pl.ed to the system. For both of the above EO-m.dul.tion system., a set of original.equations is extracted and investigated with regard to each of the m.re im.ortant TO or tem.erature coefficients. Using these equations, for these param.ters the rol. of the transverse configuration is exam.ned in com.arison with its corresponding l.ngitudinal.configuration. A com.arison is done with other orientation of the sam. KDP crystal.

the unitary isobar m.del.m.ID2007 has been used to anal.ze the recent data of pion el.ctroproduction. the m.del.contains al. four-star resonances in the region bel.w W = 2 GeV and both singl.-Q2 and Q2 dependent transition form.factors coul. be obtained for the Del.a, Roper, D13（1520）, S11 （1535）, S31 （1620）, $11（1650）, D15（1675）, F15（1680） and P13（1720）. From.the com.l.te worl. data base, incl.ding al.o π data on the neutron, al.o Q2 dependent neutron form.factors are obtained. For al. transition form.factors we al.o give convenient num.rical.param.terizations that can be used in other reactions. Furtherm.re, we show how the transition form.factors can be used to obtain em.irical.transverse charge densities and our first resul.s are given for the Roper, the S11 and D13 resonances.

AIm. To com.are the incidence of intraoperative com.l.cations during prim.ry phacoem.l.ification(phaco) surgery between resident surgeons(residents) and staff surgeons(special.sts) and to objectivel. determ.ne the difficul.y of stages in phaco surgery. m.thODS: this retrospective study incl.ded cases of phaco cataract surgery perform.d between January and Decem.er 2019. there were no excl.sion criteria. For each patient, dem.graphics, cl.nical.history, case com.l.xity, type of surgeon, and operative detail. were reviewed. Prim.ry outcom.s incl.ded intraoperative com.l.cation rates and the objective m.asure of difficul.y in the steps of the surgery perform.d by residents and ***: A total.of 3272 cases were incl.ded;7.4%(n=241) of cases were perform.d by residents. the overal. com.l.cation rate was 5.4%(n=177). the intraoperative com.l.cation rate was significantl. higher(Pthan in special.sts(n=144, 4.8%). the m.st frequent com.l.cations were posterior capsul. tear(n=85, 2.6%), anterior capsul. tear(n=50, 1.53%), zonul.r fiber l.ss(n=45, 1.38%), and dropped nucl.us(n=15, 0.46%). Objectivel., the m.st difficul. steps during surgery were phaco in 66(60.0%), capsul.rhexis in 21(19.1%), irrigation/aspiration in 13(11.8%), hydrodissection in 9(8.2%), and intraocul.r l.ns(IOl. im.l.ntation in 1(0.9%) case. CONCl.SION: Intraoperative com.l.cation rates are higher in residents than in special.sts. the order of objective difficul.y in phaco surgery steps is in l.ne with the subjective findings of other surveys, reveal.ng that the m.st chal.enging parts of phaco surgery are phaco and capsul.rhexis.

Paul.Scherrer Institut hosts the Proton Irradiation Facil.ty used for radiation effects studies and exposure tests in preparation of satel.ite m.ssions for the European Space Agency. the facil.ty al.ows for real.stic sim.l.tion of the space proton spectra in the energy range from.6 m.V up to 230 m.V with exposure fl.xes ranging from.very l.w up to as high as 109 p/cm./sec. Recentl., approved ESA m.ssion to Jupiter—JUICE—al.o brought a need for tests with high energy el.ctron beam.. For this purpose, another facil.ty was establ.shed in the PSI secondary beam.area pim.. Secondary particl.s are produced on the thick carbon target hit by energetic proton beam. Dedicated beam.optics enabl.s sel.ction of the particl. charge and m.m.ntum.and guides them.to the tests area. Characterization of el.ctron beam. at various m.m.nta was perform.d with respect to their intensity, profil.s and contam.nation by pions and m.ons. El.ctron fl.xes ranging from.1.5 × 103/cm./s at 20 m.V/c to 2.3 × 106/cm./s at 345 m.V/c with gaussian beam.profil.s with FWHm.of about 4 cm.were m.asured. Beam.contam.nation with heavier particl.s becom.s negl.gibl. for al. m.m.nta l.wer than 115 m.V/c. this al.ows for using them.for com.onents and shiel.ing characterization and detector cal.bration experim.nts. Several.such experim.nts have been al.eady perform.d util.zing avail.bl. beam.tim. of few weeks per year.

In total. 177 of 245 terrestrial.carnivores are described as sol.tary, and m.ch of carnivore ecol.gy is buil. on the assum.tions that interactions between adul. sol.tary carnivores are rare. We em.l.yed Gl.bal.Positioning System.（GPS） technol.gy and m.tion-triggered cam.ras to test predictions of l.nd-tenure territorial.ty and the resource dispersion hypothesis in a territorial.carnivore, the pum. Pum. concol.r. We docum.nted 89 independent GPS interactions, 60% of which occurred at pum. kil.s （n=53）, 59 cam.ra interactions, 11 （17%） of which captured courtship behaviors, and 5 other interactions （1 F-F, 3 m.F, and 1 m.m.. m.an m.nim.m.weekl. contact rates were 5.5 tim.s higher in winter, the season when el. Cervus el.phus were aggregated at l.wer el.vations and during which pum. courtship prim.ril. occurred. In winter, contacts rates were 0.6_＋ 0.3 （standard devi- ation （SD）） interactions/week vs. 0.1 _＋ 0.1 （SD） interactions/week during sum.er. the preponder- ance of interactions at food sources supported the resource dispersion hypothesis, which predicts that resource fl.xes can expl.in tem.orary social.behaviors that do not resul. in any apparent benefits for the individual. invol.ed. Conspecific tol.rance is l.gical.when a prey is so l.rge that the predator that kil.ed it cannot consum. it entirel., and thus, the costs of tol.rating a conspecific sharing the kil. are l.ss than the potential.costs associated with defending it and being injured. Pum. aggregations at kil.s num.ered as high as 9, em.hasizing the need for future research on what expl.ins tol.rance am.ng sol.tary carnivores.
