Abstract (sommario):

One of the biggest problems to predict the bending fatigue life of gear is lack of S-N data from the standard gear specimen. It is expensive and long time to spend to do the specimen tests. The bending fatigue property data from database is not enough to fulfill the engineering needs. To solve the problem, multiaxial methods are used to predict the bending fatigue life of gears and FEA method is used to analyze the stress of gear teeth root. Result shows that McDiarmid model, Findley model and Maximum shear stress model fulfill the engineering needs and McDiarmid method is the most accurate.

Abstract (sommario):

The fossorial snake genus Anomalepis Jan 1860 currently comprises four species with distribution restricted to the Neotropics, occurring from Nicaragua to trans-Andean Peru. Species of Anomalepis occur on the mainland from sea level to about 2,700 m elevation in habitats that range from xerophyte vegetation to tropical wet forests (Kofron 1988; McDiarmid et al. 1999; Uetz et al. 2019; Wallach et al. 2014). Kofron (1988) performed a taxonomic review of the genus Anomalepis, recognizing two phenotypic clusters of species: the A. mexicanus Jan 1860 composed exclusively by its nominal form, and the A. aspinosus Taylor 1939 group consisting of the former species, A. colombia Marx 1953 (Fig. 1) and A. flavapices Peters 1957. While Anomalepis aspinosus occurs in xerophytic formation from 500–2700 above sea level (asl hereafter) along the Peruvian Andes (Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014), and Anomalepis flavapices is found in the coastal rainforest plains of northwestern Ecuador (Kofron 1988; Wallach et al. 2014), Anomalepis mexicanus presents the most widespread distribution amongst its congeners, occurring in northeastern Honduras, Nicaragua, Costa Rica and Panama from sea level to 725 m altitude. Even though this species has previously been recorded for Peru (Kofron, 1988), it seems unlikely that this specimen belongs to A. mexicanus due to its distinct meristic features (see Kofron 1988) and its outlandish record (see Fig. 2). Marx (1953) described Anomalepis colombia based on a single specimen collected in 1946 by Kjell von Sneidern at La Selva (05º25’23N, 74º57’44W; 1700 m asl), municipality of Pueblo Rico, department of Caldas, Colombia. As far as we know, since its original description, no additional specimen of A. colombia has been reported in literature (cf. Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014).

Testo completo

Abstract (sommario):

The Glassfrog Centrolenella puyoensis Flores & McDiarmid is a taxon known only from the female holotype, and recently placed in the genus Centrolene due to its supposed close relationship with Centrolene mariae (Duellman & Toft). Herein we report new material of puyoensis, including adult male specimens previously unknown. We propose the new combination Cochranella puyoensis (Flores & McDiarmid) n. comb., in recognition of the state of the humeral crista ventralis in males of this species, which lack a humeral spine. The hypothesis of relationships between three species, including puyoensis, proposed as the mariae species-group is questioned as it was based on phenetic rather than derived characters. We present new data that extend the distributional range of Cochranella puyoensis, and define its range along the Foothill Evergreen forests from 400 m to 1000 m above sea level in the provinces of Napo, Orellana, and Pastaza. New data presented herein also permit a re-evaluation of the conservation status of the species, previously classified under the IUCN category of Critically Endangered. We recommend that Cochranella puyoensis be reclassified as “Endangered”: EN B1ab(i,ii,iii)+2ab(i,ii,iii); based on a better understanding of the presence of the species, its occupancy area, number of known localities, and habitat quality status.

Abstract (sommario):

The prevention of fatigue failure is an important consideration in the design of aeroengine shafts. In this paper, based on the elastic and elstic-plastic finite element analyses, for a series of small-scale hollow shafts with transverse holes, the maximum princple stress and von Mises stresss around the hole have been obtained. Hence, using McDiarmid and Von Mises criteria, the fatigue crack initiation site and life can be determined. The hoop stress, which is the driving force for the Mode I growth of short cracks initiated around the hole, has been characterised as well.

Abstract (sommario):

It has already been suggested that snake head triangulation might be related to mimicry of the head shape of vipers (Greene & McDiarmid 2005, and references therein). Until very recently, this hypothesis has never been experimentally tested. We first tested the hypothesis of snakes’ head shape as a dangerous signal to predators by use of plasticine models (Guimarães & Sawaya 2011). We suggested in that study that shape of the head does not confer advantage itself but may work in synergy with a set of traits including colour and behavioural displays that warn and discourage predator attacks.

Abstract (sommario):

For two steels with different material properties (both cyclic and static ones) were experimentally obtained dependencies σa=f(Nf) and σa=f(Nf). The specimens of these materials were loaded with multiple tensile and torsion stress combinations. It was found out that the time-depending relationship between the individual stresses was proportional. The results for steel with high ration of Rm/Re are different comparing to the results of the second material. In this contribution, there will be confronted the experimentally obtained fatigue life-time magnitudes with selected multiaxial fatigue life-time hypotheses like Findley, McDiarmid, Dang-Van, Carpinteri-Spagnioli, and Margetin-Ďurka-Chmelko.

Abstract (sommario):

Soluble carbohydrates are the major nutritional reward in the pulp of most vertebrate dispersed fruits (Corlett 1996, Herrera 1987, Johnson et al. 1985, Jordano 1995). However, although detailed analyses have been made of the carbohydrate content of many cumtivated fruits (e.g. Nagy et al. 1990, Widdowson & McCance 1935), most studies of wild fruits have only quantified total soluble carbohydrates (e.g. Conklin & Wrangham 1994, Corlett 1996, Foster & McDiarmid 1983, Herrera 1987, Izhaki 1992). This is unfortunate because relatively minor differences in the chemical structure of nutrients can have profound implications for frugivorous animals (Martinez del Rio & Restrepo 1993), and the fruit choices of these animals in turn, may have major implications for the abundance and distribution of the plant species.

Abstract (sommario):

Glassfrogs (family Centrolenidae) constitute a diverse Neotropical group of epiphyllous and arboreal anurans (Señaris & Ayarzagüena 2005; Guayasamin et al. 2009). They are commonly encountered on stream-side vegetation and many species may show high densities during their reproductive season, with numerous territorial males calling for mates in relative small areas (Señaris & Ayarzagüena 2005; Kubicki 2007; Delia et al. 2010). Territoriality of males in several glassfrog species occasionally implies combat behaviors. Combat behavior has been poorly documented in glassfrogs, mainly reported from anecdotal observations in just 11 species (McDiarmid & Adler 1974; Duellman & Savitzky 1976; Greer & Wells 1980; Jacobson 1985; Restrepo-Toro 1996; Bolívar et al. 1999; Savage 2002; Guayasamin & Barrio-Amorós 2005; Kubicki 2007; Delia et al. 2010).

Testo completo

Abstract (sommario):

For most of the last 150 years, Tricheilostoma Jan, 1860 has resided in the synonymy of other snake genera such as Glauconia Gray, 1845 and Leptotyphlops Fitzinger, 1843 (Boulenger, 1893; McDiarmid et al., 1999). Thus there has been less practical concern over the identity of the type species. This changed recently with the proposal of a new classification of the family Leptotyphlopidae and resurrection of the Genus Tricheilostoma (Adalsteinsson et al., 2009). Pinto et al. (2010) alluded to a potential taxonomic problem with the type species of that genus, but determined that no change was necessary. However, the problem remains and affects 15 species of South American and African snakes. The purpose of this note is to resolve the issue and make the necessary taxonomic changes.

Abstract (sommario):

A comparative study is made of the applicability of critical plane based multiaxial high cycle fatigue models to predicting the fatigue behavior of metallic materials. A number of models, namely Matake, McDiarmid, Carpinteri and Spagnoli, Liu and Mahadevan and Papadopoulos, were applied to fatigue limit states, involving synchronous fully reversed in-phase sinusoidal bend and torsion loading. The results obtained indicated a good predictive capability of the models with an average error index situated approximately between -5,5% and 4,5%. However, this average was limited to less than 3% for the latter three models. Finally, the critical plane orientation, which, for a given material, is characteristic of the proper model, is compared with that of the fracture plane, exclusively determined by the ratio between the shear stress and normal stress amplitudes.

Abstract (sommario):

In this paper, the viewpoint that maximum resolved shear stress corresponding to the two slip systems in a nickel-based single crystal high-temperature fatigue experiment works together was put forward. A nickel-based single crystal fatigue life prediction model based on modified resolved shear stress amplitude was proposed. For the four groups of fatigue data, eight classical fatigue life prediction models were compared with the model proposed in this paper. Strain parameter is poor in fatigue life prediction as a damage parameter. The life prediction results of the fatigue life prediction model with stress amplitude as the damage parameter, the fatigue life prediction model with maximum resolved shear stress in 30 slip directions as the damage parameter, and the McDiarmid (McD) model, are better. The model proposed in this paper has higher life prediction accuracy.

Abstract (sommario):

Often when analysing randomized algorithms, especially parallel or distributed algorithms, one is called upon to show that some function of many independent choices is tightly concentrated about its expected value. For example, the algorithm might colour the vertices of a given graph with two colours and one would wish to show that, with high probability, very nearly half of all edges are monochromatic.The classic result of Chernoff [3] gives such a large deviation result when the function is a sum of independent indicator random variables. The results of Hoeffding [5] and Azuma [2] give similar results for functions which can be expressed as martingales with a bounded difference property. Roughly speaking, this means that each individual choice has a bounded effect on the value of the function. McDiarmid [9] nicely summarized these results and gave a host of applications. Expressed a little differently, his main result is as follows.

Abstract (sommario):

A class of graphs is calledbridge-addableif, for each graph in the class and each pairuandvof vertices in different components, the graph obtained by adding an edge joininguandvmust also be in the class. The concept was introduced in 2005 by McDiarmid, Steger and Welsh, who showed that, for a random graph sampled uniformly from such a class, the probability that it is connected is at least 1/e.We generalize this and related results to bridge-addable classes with edge-weights which have an edge-expansion property. Here, a graph is sampled with probability proportional to the product of its edge-weights. We obtain for example lower bounds for the probability of connectedness of a graph sampled uniformly from a relatively bridge-addable class of graphs, where some but not necessarily all of the possible bridges are allowed to be introduced. Furthermore, we investigate whether these bounds are tight, and in particular give detailed results about random forests in complete balanced multipartite graphs.

Abstract (sommario):

One of the most crucial tasks in fatigue life-time estimation of components loaded with multiaxial variable amplitude loading is to correctly identify loading cycles that can be used with multiaxial damage criterions. During past years, several cycle counting methods have been proposed for multiaxial loading conditions. The aim of this text is the comparison of selected multiaxial cycle counting methods, namely Wang-Brown’s method, Modified Wang-Brown’s method, Bannantine-Socie’s method and then a critical analysis of the obtained results. For the comparison of chosen methods, a new data set, consisting of experimentally obtained results from multiaxial non-proportional variable amplitude loading tests carried on by authors, has been used. The tested specimens were made from S355J0 structural steel and the testing procedure has been carried out on the MTS Axial/Torsion servo hydraulic testing machine. Findley and McDiarmid multiaxial criterion with Palgren-Miner summation rule have been used for fatigue life-time estimation of the tested specimens.

Testo completo

Abstract (sommario):

In this paper, a life prediction model associated with maximum principal stress and equivalent shear amplitude based on twin-shear unified yield criterion for multiaxial high-cycle fatigue is proposed. The equivalent shear amplitude is the normalized format of the equivalent shear amplitude based on clusters of yield criteria embodying Tresca and the linearization of Huber-von Mises, extending the application to metallic materials. Simultaneously, the effect of mean stress on multiaxial high-cycle fatigue is considered in the proposed model. As an assessment of the new prediction model, the criterion is compared with experimental data of aluminum alloy LY12CZ and carbon structural steel SM45C published in the relevant literature, which shows that most of the data are located within an error range of less than two times the data and are in good agreement with the experiment. Moreover, the proposed model is also compared with other models, such as McDiarmid, Liu, and Freitas, to validate its competitiveness.

We report new distributional information for Eleutherodactylus mercedesae in Bolivia, and provide the first record for Peru based on an adult female. This species, previously endemic to Bolivia, now ranges across about 1000 km in cloud forests on the Amazonian slopes of the Andes from southern Peru to central Bolivia. We provide the first morphological description of females based on two specimens, compare them with the male type and paratype, add some observations to the original description, and comment on variation in the species.

Abstract (sommario):

Let${\cal A}$be a minor-closed class of labelled graphs, and let${\cal G}_{n}$be a random graph sampled uniformly from the set ofn-vertex graphs of${\cal A}$. Whennis large, what is the probability that${\cal G}_{n}$is connected? How many components does it have? How large is its biggest component? Thanks to the work of McDiarmid and his collaborators, these questions are now solved when all excluded minors are 2-connected.Using exact enumeration, we study a collection of classes${\cal A}$excluding non-2-connected minors, and show that their asymptotic behaviour may be rather different from the 2-connected case. This behaviour largely depends on the nature of the dominant singularity of the generating functionC(z) that counts connected graphs of${\cal A}$. We classify our examples accordingly, thus taking a first step towards a classification of minor-closed classes of graphs. Furthermore, we investigate a parameter that has not received any attention in this context yet: the size of the root component. It follows non-Gaussian limit laws (Beta and Gamma), and clearly merits a systematic investigation.

Abstract (sommario):

Suppose that [Cscr ]={cij[ratio ]i, j[ges ]1} is a collection of i.i.d. nonnegative continuous random variables and suppose T is a rooted, directed tree on vertices labelled 1,2,[ctdot ],n. Then the ‘cost’ of T is defined to be c(T)=[sum ] (i,j)∈Tcij, where (i, j) denotes the directed edge from i to j in the tree T. Let Tn denote the ‘optimal’ tree, i.e. c(Tn) =min{c(T)[ratio ]T is a directed, rooted tree in with n vertices}. We establish general conditions on the asymptotic behaviour of the moments of the order statistics of the variables c11, c12, [ctdot ], cin which guarantee the existence of sequences {an}, {bn}, and {dn} such that b−1n (c(Tn)−an) →N(0, 1) in distribution, d−1nc(Tn)→1 in probability, and d−1nE(c(Tn))→1 as n→∞, and we explicitly determine these sequences. The proofs of the main results rely upon the properties of general random mappings of the set {1, 2, [ctdot ], n} into itself. Our results complement and extend those obtained by McDiarmid [9] for optimal branchings in a complete directed graph.

Abstract (sommario):

Corpora show that people are less original in using language than is generally believed. We routinely employ an immense repertoire of semi-preconstructed phrases, though we also adapt them: creative extensions and adaptations of institutionalized locutions sometimes occur more frequently than the ordinary form. Corpora also reveal that fiction uses verbal idioms rarely found in other forms of writing or in conversation, which suggests that novelists draw on their own experience of stereotyped fictional dialogue more than on real-life conversation. Oral epic poetry, from Homer to Beowulf, was, of course, also formulaic, but the received view is that written poetry should be quite the opposite: it should consist of new combinations of words. While it is easy to find poetry that does contain fixed expressions and poetic transformations of them, such as the ‘conversational’ (and occasionally prosaic) poetry of Wordsworth, Frost, Auden and McDiarmid, it is harder to argue that the poetry of Shakespeare, Donne, Shelley, Keats, Hopkins, Stevens or Ashbery is made up of formulaic language. Conversely, however, it can be shown that canonical poetry is the source of hundreds of phrases in our active verbal lexicons.

Abstract (sommario):

AbstractA class of graphs is bridge-addable if given a graph $G$ in the class, any graph obtained by adding an edge between two connected components of $G$ is also in the class. The authors recently proved a conjecture of McDiarmid, Steger, and Welsh stating that if ${\mathcal{G}}$ is bridge-addable and $G_{n}$ is a uniform $n$-vertex graph from ${\mathcal{G}}$, then $G_{n}$ is connected with probability at least $(1+o_{n}(1))e^{-1/2}$. The constant $e^{-1/2}$ is best possible, since it is reached for the class of all forests.In this paper, we prove a form of uniqueness in this statement: if ${\mathcal{G}}$ is a bridge-addable class and the random graph $G_{n}$ is connected with probability close to $e^{-1/2}$, then $G_{n}$ is asymptotically close to a uniform $n$-vertex random forest in a local sense. For example, if the probability converges to $e^{-1/2}$, then $G_{n}$ converges in the sense of Benjamini–Schramm to the uniformly infinite random forest $F_{\infty }$. This result is reminiscent of so-called “stability results” in extremal graph theory, the difference being that here the stable extremum is not a graph but a graph class.

Abstract (sommario):

The family Centrolenidae contains about 148 species (Frost 2009), 11 genera and two subfamilies, distributed from southern Mexico to Panama, through the Andes from Venezuela to Bolivia, with species in the Amazon and Orinoco river basins, the Guiana Shield region, and the Atlantic forests of southeastern Brazil and northeastern Argentina (Guayasamin et al. 2009). The subfamily Centroleninae contains nine genera (Centrolene, Chimerella, Cochranella, Espadarana, Nymphargus, Rulyrana, Sachatamia, Teratohyla, and Vitreorana; Guayasamin et al. 2009). In spite of the high diversity in this subfamily, only the larvae of 15 species are well known (Centrolene altitudinale, C. daidaleum, C. geckoideum, C. hesperium, C. venezuelense, Cochranella granulosa, Espadarana andinum, E. prosoblepon, Teratohyla midas, T. pulverata, T. spinosa, Vitreorana castroviejoi, V. eurygnatha, V. helenae, and V. uranoscopa - Starret 1960; Duellman 1978; Heyer 1985; Cadle & McDiarmid 1990; Mijares-Urrutia 1990; Rada de Matinez 1990; Rueda-Almonacid 1994; Hoffmann 2004; Señaris & Ayarzagüena 2005; Rada et al. 2007). Thirteen of them are associated with Amazonian forests or forested slopes of the Andes (Frost 2009). The tadpole of Vitreorana oyampiensis (=Cochranella oyampiensis) has not been formally described; it was mentioned briefly (diagrammatic drawings and larval color notes) in Hero´s tadpole identification key from Central Amazonia (Hero 1990). In this paper we describe the tadpoles of V. oyampiensis and also provide comments on the spawning sites, clutch size, breeding periods and development site of tadpoles.

Abstract (sommario):

Fretting can be defined as small-amplitude oscillatory motions between two solid surfaces in contact. It has been known for a long time that such loading introduces cracking and/or wear in many structural parts. For very small amplitudes, the contact presents a composite structure where, during the loading cycle, some domains remain stuck whereas others endure sliding. Such a partial slip condition mainly favours crack nucleation and crack propagation. The loading path imposed through the contact requires precise identification of the sliding condition and the local friction coefficient operating through the sliding domain. An energy approach is here developed combining the online identification of the sliding domain and the determination of the local friction coefficient. A normalized fretting sliding chart is introduced and discussed, taking into account the impact of plasticity on the sliding condition. Applying analytical and finite element model computations, it has been shown that crack nucleation under stabilized partial slip can be predicted by transposing multiaxial fatigue criteria (Dang Van, Crossland, McDiarmid and Smith-Watson-Topper). Such a prediction nevertheless requires that the high stress gradient imposed by the contact loading is taken into account. The loading states, which are computed to determine the risk of crack nucleation, must be averaged over an elementary volume whose length scale can be compared with the microstructure.

Abstract (sommario):

Nyctimantis galeata (Pombal, Menezes, Fontes, Nunes, Rocha & Van Sluys) is a casque-headed frog member of the Lophyohylini tribe (Blotto et al. 2020), narrow-endemic to the municipality of Morro do Chapéu, Bahia state, Brazil (Pombal et al. 2012). This species was initially described as sister of Corythomantis greeningi Boulenger based on shared osteological autapomorphies within Hylidae (see Faivovich et al. 2005; Pombal et al. 2012). However, in the most recent molecular phylogenetic analysis of Lophyohylini, Blotto et al. (2020) redefined the genus Nyctimantis to accommodate species from the former genus Aparasphenodon, Argenteohyla and “Corythomantis galeata” (as initially described; Pombal et al. 2012). Currently, the genus Nyctimantis comprises seven species: N. arapapa (Pimenta, Napoli & Haddad), N. bokermanni (Pombal), N. brunoi (Miranda-Ribeiro), N. galeata, N. pomba (Assis, Santana, Silva, Quintela & Feio), N. rugiceps Boulenger, and N. siemersi (Mertens). Among these, N. arapapa (Lourenço-de-Moraes et al. 2013), N. brunoi (Wogel et al. 2006) and N. siemersi (Céspedez 2000; Cajade et al. 2010) have their tadpoles described, while oral cavity anatomy was only reported for those of N. brunoi and N. siemersi (Wogel et al. 2006; Cajade et al. 2010). Considering that larval morphology generally provides reliable information for anuran systematic and taxonomic studies (Wassersug 1980; McDiarmid & Altig 1999; Haas 2003), a formal comparison of these larvae might highlight additional non-molecular evidence that support them as congeners (Blotto et al. 2020). Herein, we describe the external morphology and oral cavity anatomy of tadpoles of N. galeata and compare it with those of related species.
