In the present paper, asimple mechanical mod.lis d.veloped.to pred.ct thed.namic response of a cracked.structure subjected.to period.c excitation, which has been used.to id.ntify the physical mechanisms in lead.ng the growth or arrest of cracking. The structure und.r consid.ration consists of a beam with a crack along the axis, and.thus, the crack may open in Mod. I and.in the axial d.rection propagate when the beam vibrates. In this paper, the system is mod.led.as a cantilever beam lying on a partial elastic found.tion, where the portion of the beam on the found.tion represents the intact portion of the beam. Mod.l analysis is employed.to obtain a closed.form solution for the structural response. Crack propagation is stud.ed.by allowing the elastic found.tion to shorten （mimicking crack growth） if a d.splacement criterion, based.on the material toughness, is met. As the crack propagates, the structural mod.l is upd.ted.using the new found.tion length and.the response continues. From this work, two mechanisms for crack arrest are id.ntified. It is also shown that the crack propagation is strongly influenced.by the transient response of the structure.

Epitypification can solve many taxonomic problems and.stabilize the und.rstand.ng of species, genera, families or ord.rs. The aim of this paper is to illustrate how to epitypify. A few examples where taxa have been epitypified.are consid.red.and.the benefits and.d.sad.antages of epitypification are d.scussed. We also outline some examples of taxa which need.to be epitypifled.with reasons.

Fallen leaves of Ficus altissima, F. virens, F. benjamina, F. fistulosa and.F. semicord.ta, were collected.in Chiang Mai Province in northern Thailand.and.examined.for fungi. Eighty taxa were id.ntified. comprising 56 anamorphic taxa, 23 ascomycetes and.l basid.omycete. Common fungal species occurring on five host species with high frequency of occurrence were Beltraniella nilgirica, Lasiod.plod.a theobromae, Ophioceras leptosporum, Periconia byssoid.s and.Septonema harknessi. Colletotrichum and.Stachybotrys were also common genera. The leaves of d.fferent Ficus species supported.d.verse fungal taxa, and.the fungal assemblages on the d.fferent hosts showed.varying overlap. The fungal d.versity of saprobes at the host species level is d.scussed.

Mod. jumping is an instability phenomenon in the post-buckling region, which causes a sud.en change in the equilibrium configuration and.is thus harmful to structure. The con- figuration of a partial elastic found.tion can d.rectly ind.ce mod. coupling from the buckling stage and.through the whole post-buckling region. The mod. coupling effect d.e to the configuration of partial found.tion on mod. jumping is investigated.and.d.monstrated.to be an important factor of d.termining mod. jumping. By properly choosing the partial elastic found.tion configuration, mod. jumping can be avoid.d.

Sporid.smiopsis zhejiangensis sp. nov. and.Spad.coid.s americana were found.on submerged.wood.from streams in Zhejiang Province, China. Sporid.smiopsis zhejiangensis is characterized.by obclavate to fusiform, 5-6-d.stoseptate, versicolor-ous, verruculose conid.a with an apical mucilaginous sheath. Spad.coid.s americana is a new record.to China. These taxa are d.scribed.and.illustrated. and.morphological d.fferences between these species and.their similar species were summarized.

We present an overview of previous research results on the molecular phylogenetic analyses in Agaricales and.its higher ranks (Agaricomycetes/Agaricomycotina/Basid.omycota) along with the most recent treatments of taxonomic systems in these taxa. Establishing phylogenetic hypotheses using d.A sequences, from which an und.rstand.ng of the natural evolutionary relationships amongst clad.s may be d.rived. requires a robust d.taset. It has been recognized.that single-gene phylogenies may not truly represent organismal phylogenies, but the concord.nt phylogenetic genealogies from multiple-gene d.tasets can resolve this problem. The genes commonly used.in mushroom phylogenetic research are summarized.

A general formulation is d.veloped.for the contact behavior of a finite circular plate with a tensionless elastic found.tion. The gap d.stance between the plate and.elastic found.tion is incorporated.as an important parameter. Unlike the previous mod.ls with zero gap d.stance and.large/infinite plate rad.us, which assumes the lift-off/separation of a flexural plate from its supporting elastic found.tion, this stud. shows that lift-off may not occur. The results show how the contact area varies with the plate rad.us, bound.ry cond.tions and.gap d.stance. When the plate rad.us becomes large enough and.the gap d.stance is red.ced.to zero, the converged.contact rad.us close to the previous ones is obtained.

Abstract This summary report highlights the confluence of continued.d.wnward.pressures and.d.flation scares in the face of looming uncertainty in China＇s key macroeconomic land.capes. Counterfactual analyses and.policy simulations are cond.cted. in ad.ition to benchmark forecasts, based.on IAR-CMM mod.l and.taking into account both cyclical and.secular factors. Economic d.celeration is projected.to continue in the short to med.um term, with real Gd. growth d.clining to 6.3% （5.5% using more reliable instead.of official d.ta） in 2016 and.facing a significant risk of slid.ng further d.wn in 2017. Five key factors contributing to the weak outlook, ad.itional to frictions and.imped.ments associated.with economic transition/restructuring and.lackluster d.mestic/external d.mand., are id.ntified. includ.ng： lack of new growth/ d.velopment engine, exhaustion of government-led.d.iving force, the crowd.ng-out of private sectors by state-owned.enterprises （SOEs） with excess capacity／capital overhang, nonperforming government sectors and.officials, and.twist or misinterpretation of the ＂New Normal.＂ A root cause of these problems, lying with sluggishness in China＇s transformation into a market based.economy, has to d. with overpowered.government but und.rpowered.market in resource allocation and.government und.rperformance in enforcing integrity and.transparency in the marketplace and.in provid.ng public good. and.services. At the nexus between inclusive growth and.institutional transformation are market oriented.and.rule of law governed.structural reforms and.harmonious d.velopment. As such, fund.mental institutional reforms that d.alectically balance d.mand.and.supply sid. factors and.properly weigh short run stabilization against long run d.velopment should.be elevated.to the top of the agend..
