This.res.arch inves.igates.the impact of managed health care on academic medical centers.in the u.ited s.ates. Academic medical centers.hold a u.iqu. pos.tion in the u. s. health care s.s.em throu.h their mis.ions.of condu.ting cu.ting-edge biomedical res.areh, pu.s.ing clinical and technological innovations.

However, policies.to control cos.s.throu.h the u.0} of managed care and limiting res.u.ces.are detrimental to academic medical centers.and impede the advancement of medical s.iTo s.rvive the threats.of managed care in the health care environment, acadendc medical centers.mu.0} rely on their u.per level managers.to derive s.cces.fu. s.rategies. The methods.u.0}d in this.s.u.y inclu.e qu.litative approaches.in the form of key informants.and cas. s.u.ies. In addition, a s.rvey qu.s.ionnaire was.s.nt to 1h8 CEOs.in all the academic medical centers.in the u. s. The findings.revealed that managers.who perform the liais.n, monitor, entrepreneu. and res.u.ce allocator roles.are cru.ial to ens.re the s.rvival of academic medical centers. s. that academic medical centers.can continu. their mis.ions.to s.rve the general pu.lic and promote their well-being.

We determine the behavior of track etch rate VT along the tracks.in CR-39 detectors.expos.d to fis.ion fragments.from ^252Cf s.u.ce. CR-39 detectors.are etched at 70℃ in different concentrations.of Na2COa-mixed 6M NaOH s.lu.ions.for different etching time intervals.of 5-10min s.arting from 15 min u. to 210min. Two valu.s.of track etch rate are determined along the fis.ion fragment trajectories. The variation in VT is.correlated with the energy los. rate of the fis.ion fragment in the detector material.

In this.paper a non-iterative techniqu. is.developed for the correction of fau.ty antenna array bas.d on matrix pencil techniqu.（MPT）. The failu.e of a s.ns.r in antenna array can damage the radiation power pattern in terms.of s.delobes.level and nu.ls. In the developed techniqu., the radiation pattern of the array is.s.mpled to form dis.rete power pattern information s.t. Then this.information s.t can be arranged in the form of Hankel matrix（HM） and execu.e the s.ngu.ar valu. decompos.tion（s.D）. By removing nonprincipal valu.s. we obtain an optimu. lower rank es.imation of HM. This.lower rank matrix corres.onds.to the corrected pattern. Then the propos.d techniqu. is.employed to recover the weight excitation and pos.tion allocations.from the es.imated matrix. Nu.erical s.mu.ations.confirm the efficiency of the propos.d techniqu., which is.compared with the available techniqu.s.in terms.of s.delobes.level and nu.ls.

Adaptive traffic light s.hedu.ing bas.d on realtime traffic information proces.ing has.proven effective for u.ban traffic conges.ion management. However, fine-grained information regarding individu.l vehicles.is.difficu.t to acqu.re throu.h traditional data collection techniqu.s.and its.accu.acy cannot be gu.ranteed becau.0} of conges.ion and hars. environments. In this.s.u.y, we firs. bu.ld a pipeline model bas.d on vehicle-to-infras.ru.tu.e commu.ication, which is.a s.lient techniqu. in vehicu.ar adhoc networks. This.model enables.the acqu.s.tion of fine-grained and accu.ate traffic information in real time via mes.age exchange between vehicles.and roads.de u.its. We then propos. an intelligent traffic light s.hedu.ing method (ITLM) bas.d on a “demand as.ignment” principle by cons.dering the types.and tu.ning intentions.of vehicles. In the context of this.principle, a s.gnal phas. with more vehicles.will be as.igned a longer green time. Fu.thermore, a green-way traffic light s.hedu.ing method (GTLM) is.inves.igated for s.ecial vehicles.(e.g., ambu.ances.and fire engines. in emergency s.enarios. s.gnal s.ates.will be adju.0}ed or maintained by the traffic light control s.s.em to keep s.ecial vehicles.moving along s.oothly. Comparative experiments.demons.rate that the ITLM redu.es.average wait time by 34%-78% and average s.op frequ.ncy by 12%-34% in the context of traffic management. The GTLM redu.es.travel time by 22%^44% and 30%-55% u.der two types.of traffic conditions.and achieves.optimal performance in conges.ed s.enarios.

In the photodetachment of atoms.or negative ions.by a dou.le-pu.s. las.r, the firs. pu.s. of the dou.le-pu.s. las.r generates.waves.and the delayed s.cond pu.s. may detect them. The phenomenon of the excitation and detection of waves.by a dou.le-pu.s. las.r can be u.0}d to identify the clos.d orbits.in the s.s.em. We demons.rate this.phenomenon with a negative hydrogen ion(H^-) by analyzing the total popu.ation excited by a dou.le-pu.s. las.r in a timedependent field for different phys.cal parameters. By analyzing the total excited popu.ation u.0}ng a dou.le-pu.s. las.r, we can u.cover all the clos.d orbits.exis.ing in the s.s.em. We demons.rate that this.can be realized by s.anning the firs. pu.s. pos.tion and the time delay between the two pu.s.s.

In Febru.ry 2006, two ou.breaks.of highly pathogenic avian influ.nza A viru.0}s.btype H5N1 occu.red in chickens.in two neighboring dis.ricts.（firs. in Nandu.bar and s.cond in Jalgaon） of Maharas.tra, India, in a s.an of 12 days. In the pres.nt s.u.y, the neu.aminidas. （NA） gene of the two Indian H5N1 is.lates.was.taken into cons.deration to find if the two s.rains.are genetically s.milar. Phylogenetic analys.s.of the NA gene s.owed that the H5N1 s.rains.is.lated from the two ou.breaks.were not originated from the s.me s.u.ce. The firs. Indian is.late （Nandu.ar/7972/06） was.clu.0}ered clos.s. to an is.late from chicken in Vietnam in 2004, whereas.the s.cond Indian is.late （Jalgaon/8824/06） s.owed res.mblance to s.rains.is.lated from s.an in Italy and Iran in 2006. Moreover, amino acid s.qu.nce analys.s.s.owed varying hot s.ots.for s.bs.itu.ions.between thes. two Indian is.lates. and three s.bs.itu.ions.were fou.d at fu.ctional domain s.tes. s.condary s.ru.tu.e changes.du. to thes. s.bs.itu.ions.were als. reported. This.s.u.y reveals.that the H5N1 s.rains.is.lated from chickens.du.ing 2006 bird flu.ou.breaks.in two neighboring dis.ricts.of Maharas.tra, India are genetically different.
