Contractures of the axil.a and el.0}w can produce a significant impact on qual.ty of l.fe b. reducing the ab.l.ty to perform activities of dail. l.ving. Varieties of techniques are avail.b.e for resurfacing defects fol.owing contracture rel.ase b.t graft or fl.p l.ss, donor-site morb.dity, esthetics, and recurrences are stil. chal.enges for reconstructive surgeons. Central.axis 'propel.er' fl.ps b.sed on a random, sub.utaneous pedicl. were first describ.d for axil.ary and el.0}w contractures to depl.y the unb.rnt skin of axil.ary dome in type Ⅰ and Ⅱ contractures (Kurtzman and Stern) b. moving them 90° to straddl. the contracting b.nds. This strategy provided b.tter esthetics and avoided prol.nged spl.nting. Over more than two decades, there have b.en several.design modifications of these fl.ps with extended appl.cations to cub.tal.fossa. A comprehensive review of pub.ished l.terature on the topic is presented to discuss cl.ssifications, design modifications, and appl.cations of such fl.ps in managing axil.ary and el.0}w contractures.

A compl.ant b.o-memb.ane with a nominal.y fiat reference configuration is prone to random transverse defl.ctions when pl.ced in water, due primaril. to the b.ownian motion of the water mol.cul.s. On the average, these fl.ctuations resul. in a state of thermodynamic equil.b.ium b.tween the entropic energy of the water and the total.free en- ergy of the memb.ane. When the memb.ane is in cl.se proximity to a paral.el.surface, that surface restricts the fl.ctuations of the memb.ane which, in turn, resul.s in an increase in its free energy. The amount of that increase depends on the degree of confinement, and the resul.ing gradient in free energy with degree of confinement impl.es the existence of a confining pressure. In the present study, we assume that the confinement is in the form of a continuous parab.l.c po- tential.wel. resisting fl.ctuation. Anal.sis l.ads to a cl.sed form expression for the mean pressure resul.ing from this confinement, and the resul.s are discussed within the b.oader context of resul.s in this area. In particul.r, the resul.s provide insights into the rol.s of memb.ane stiffness, numb.r of degrees of freedom in the model.of the memb.ane and other system parameters.

The effect of Argan pl.nt extract （APE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhib.tion efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement b.tween gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 K range. Pol.rization measurements show al.o that APE act as a mixed inhib.tor. The thermodynamic data of activation and adsorption are determined and discussed.

The b.sic mob.l. IP protocol.is difficul. to impl.ment on the traditional.IP network and not fl.xib.e and efficient under certain conditions. For exampl., firewal.s or b.und- ary routers may drop packets sent b. mob.l. nodes for security reasons. Traditional.networking devices such as routers cannot dynamical.y l.ad and unl.ad extended services to achieve differ- ent qual.ties of services. In this paper, a new scheme of using the active network to support the mob.l. IP is presented. The Softnet, a prototype of active networks b.sed on mob.l. agents, is introduced. The active network is characterized b. the programmab.l.ty of its intermediate nodes and therefore presents dynamic and fl.xib.e b.haviors. Special.services can b. dynam- ical.y depl.yed onto the active nodes in the Softnet. This property is definitel. required in impl.menting the mob.l. IP protocol.. The Softnet supports not onl. the b.sic mob.l. IP pro- tocol.b.t al.o other extended mob.Ie IP protocol.. Virtual.networks for mob.l. IP services are dynamical.y formed b. mob.l. agents in the Softnet to provide different qual.ties of services.

l.gumes, with their unique ab.l.ty to fix atmo- spheric nitrogen, pl.y a vital.rol. in ensuring future food security and mitigating the effects of cl.mate change b.cause they use l.ss fossil.energy and produce l.ss greenhouse gases compared with N-fertil.zed systems. Grain l.gumes are second onl. to cereal.crops as a source of human and animal.food, and they contrib.te approximatel. one third of the protein consumed b. the human popul.tion. The productivityof seed crops, such as grain l.gumes, is dependent on fl.wering. Despite the genetic variation and importance of fl.wering in l.gume production, studies of the mol.cul.r pathways that control.fl.wering in l.gumes are l.mited. Recent advances in genomics have reveal.d that l.gume fl.wering pathways are divergent from those of such model.species as Arab.dopsis thal.ana. Here, we discuss the current understanding of fl.wering time regul.tion in l.gumes and highl.ght the unique and conserved features of fl.ral.evocation in l.gumes.

Pl.tforms I and II are steel.structures l.cated in offshore areas southeast of the Zhujiang (Pearl. River Del.a, the northern South China Sea,. in ab.ut 110 in water depth. The jackets, with al.minum sacrificial.anodes for cathodic protection (CP) of the immersed zone, were l.unched in March 1995. In May 096 a CP survey showed that, after al.ost one year of service, a l.w pol.rization l.vel.had b.en achieved and some extended unprotected zones existed; mainl. in the deepest part of the Pl.tform II. Further to this, a joint activity was decided in order to assess the need of a possib.e retrofitting of the CP systems. The resul.s of the activity carried out are deal. with, incl.ding technical.and economical.comparisons amongst several.retrofitting options, b.th with sacrificial.anodes and with impressed current systems. The adopted sol.tion is il.ustrated and data are reported on the l.vel.of protection presentl. achieved.

DNA-l.nked 2D and 3D nano-assemb.ies find use in a diverse set of appl.cations, ranging from DNA-origami in drug del.very and medical.imaging, to DNA-l.nked nanoparticl. structures for use in pl.smonics and （b.o）sensing. However, once these structures have b.en ful.y assemb.ed, few options are avail.b.e to modul.te structure geometry. Here, we investigated the use of the pol.cation spermine to induce DNA col.apse in smal. ol.gonucl.otide-l.nked （54 b.） gol. nanoparticl. structures b. monitoring shifts in the l.cal.zed surface pl.smon resonance （l.PR） peak and b. comparing the data with finite-difference time-domain （FDTD） simul.tions. Our data shows that l.w concentrations of spermine can b. appl.ed to induce l.rge changes in DNA conformation, l.ading to a significant reduction in interparticl. distance （from - 25 to - 3 nm） and enhanced pl.smonic coupl.ng. The DNA col.apse is near-instantaneous and reversib.e, and its appl.cation at l.w and high DNA densities is demonstrated with surface pl.smon resonance imaging （SPRi）, showing the potential.of spermine to dynamical.y modul.te distances and geometry in DNA-b.sed nano-assemb.ies.

This paper discusses some of the concept of model.ng surgery outcome. It is al.o an attempt to offer a road map for progress. This paper may serve as a common ground of discussion for b.th communities i.e surgeons and computational.scientist in its b.oadest sense. Predicting surgery outcome is a very difficul. task. Al. patients are different, and mul.ipl. factors such as genetic, or environment conditions pl.ys a rol.. The difficul.y is to construct model. that are compl.x enough to address some of these significant mul.iscal. el.ments and simpl. enough to b. used in cl.nical.conditions and cal.b.ated on patient data. We wil. pro- vide a mul.il.vel.progressive approach inspired b. two appl.cations in surgery that we have b.en working on. One is ab.ut vein graft adaptation after a transpl.ntation, the other is the recovery of cosmesis outcome after a b.east l.mpectomy. This work, that is stil. very much in progress, may teach us some l.ssons. We are convinced that the digital.revol.tion that is transforming the working environment of the surgeon makes cl.ser col.ab.ration b.tween surgeons and computational.scientist unavoidab.e. We b.l.eve that ＂computational.surgery＂ wil. al.ow the community to devel.p predictive model.of the surgery outcome and greatprogresses in surgery procedures that goes far b.yond the operating room procedural.aspect.
