description: Given any smooth germ of a threefold flopping contraction, we first give a combinatorial characterisation of which Gopakumar-Vafa (GV) invariants are non-zero, by prescribing multiplicities to the walls in the movable cone. On the Gromov-Witten (GW) side, this allows us to describe, and even draw, the critical locus of the associated quantum potential. We prove that the critical locus is the infinite hyperplane arrangement of Iyama and the second author, and moreover that the quantum potential can be reconstructed from a finite fundamental domain. We then iterate, obtaining a combinatorial description of the matrix which controls the transformation of the non-zero GV invariants under a flop. There are three main ingredients and applications: (1) a construction of flops from simultaneous resolution via cosets, which describes how the dual graph changes, (2) a closed formula which describes the change in dimension of the contraction algebra under flop, and (3) a direct and explicit isomorphism between quantum cohomologies of different crepant resolutions, giving a Coxeter-style, visual proof of the Crepant Transformation Conjecture for isolated cDV singularities.

Euthycaelus amandae Guadanucci & Weinmann 2014: 280, figs 3A–H.
Type material. COLOMBIA: Holotype male, MZSP 57222, Santa María, Boyacá, 7.VIII.2005, D. Weinmann & L. Alvarez leg. Paratypes: 1 female, MZSP 57223, same data as holotype; 1 male, SMF, Guamal, Meta, 13.VIII.2005, D. Weinmann leg., examined.
Additional material examined. COLOMBIA: Guaviare, San José de Guaviare, Cerro Azul; 1 male, ICN-Ar 8046, 300 masl, III.2014, E. Florez leg.
Diagnosis. Males of E. amandae differ from those of other species by the uniquely bifid aspect of the palpal bulb embolus which has a small keel and by the short spines on the retrolateral palpal tibia, arranged in two nonaligned rows and the outer row with a distal gap. Females differ from those of other species by having spermathecae composed of two protuberant triangular receptacles, well separated, with two conspicuous longitudinal striae on the dorsal face (Guadanucci & Weinmann 2014: fig. 3).
Distribution and natural history. E. amandae is known only from Colombia in the Departments of Boyacá (Santa María), Meta (Guamal) and Guaviare (San José de Guaviare, Cerro Azul; new record), between 300–800 masl (Fig. 36).This tarantula inhabits the eastern foothills of the Eastern Cordillera at the transition of the Andes and the eastern savannas and in the transition between the savannas of the Orinoquía and the Amazonian forests. These territories are characterized by their water wealth, with an annual mean temperature about 26 °C and a relatively high humidity.

description: Let $S$ be a K3 surface. We study the reduced Donaldson-Thomas theory of the cap $(S \times \mathbb{P}^1) / S_{\infty}$ by a second cosection argument. We obtain four main results: (i) A multiple cover formula for the rank 1 Donaldson-Thomas theory of $\mathrm{K3} \times E$, leading to a complete solution of this theory. (ii) Evaluation of the wall-crossing term in Nesterov's quasi-map wallcrossing between the punctual Hilbert schemes and Donaldson-Thomas theory of $\mathrm{K3} \times \text{Curve}$. (iii) A multiple cover formula for the genus $0$ Gromov-Witten theory of punctual Hilbert schemes. (iv) Explicit evaluations of virtual Euler numbers of Quot schemes of stable sheaves on K3 surfaces.

Diagnosis: Monomorphic attine ants with the antennal scrobe margins always reaching and even surpassing the posterior margin of the head; frontal and preocular carinae well marked, subparallel throughout their whole extension, limiting the impressed antennal scrobe; extremities of frontal and preocular carinae always separate and with up to three triangular or rounded compressed tubercles or vertical teeth close to the posterior margin (figs 1, 5, 9, 13, 15, 19, 23, 27); preocular carina not curved mesad above eyes. Frontal lobes from moderately approximate to moderately expanded laterad, but in most species the interfrontal width near 2/3 of the head width across the eyes (FLI 50–70). Occipital projections (teeth or spines) always present on head. Posterior margin in full-face view smoothly concave, notched in the middle. The paired vertexal carinae indicated by a series of weakly connected piligerous denticles, flanking the shallowly impressed sagital furrow, which in front joins the transverse impression of frons, behind the frontal area. Outer border of mandibles sinuous. Mandibles with discal area smooth and shining, the fine striae confined to the mandibular bases and sides. All funicular segments, including 2nd, longer than broad.

description: When three particles in three dimensions interact with a short-range potential fine-tuned to an infinite scattering length, they form an infinite sequence of loosely bound states obeying discrete scale invariance known as Efimov states. Here we show that analogous states are formed by three charged particles carrying two equal charges and one opposite charge in one, two, and three dimensions without any fine-tuning. Our finding is based on the Born-Oppenheimer approximation, where an effective inverse-square attraction is induced as a consequence of the dipole-charge interaction between a hydrogenlike heavy-light atom and a far-separated heavy particle. Because the resulting Efimovian states emerge toward the second or higher dissociation threshold, they are to be realized as quasibound states and may be observed by exciting hydrogen molecular ions and trions in excitonic systems. We also consider the same system but with a logarithmic Coulomb potential relevant to quantum vortices in two-dimensional superfluids, where the Efimovian states are shown to emerge as genuine bound states toward the first dissociation threshold.

Fig. 5.
Material.—Early Pleistocene: one left cleithrum (NMNHU-P 53/4249, Nova Etuliya); one fragment of cleithrum (NMNHU-P 53/4250, Sinyaya Balka). Middle Pleistocene: one left palatine and two left dentaries (NMNHU-P 53/4253, Semibalka 1); one parasphenoid, two right palatines, two left and six right dentaries (NMNHU-P 53/4254–4264, Medzhibozh).
Emended diagnosis.— Esox lucius is characterized by a number of features distinguishing it from other species: (i) only uniserial dentition of dentary; (ii) narrow dental shelf; (iii) presence of symphysial notch; (iv) clearly expressed and anteromedially deepened carotid grooves on parasphenoid; (v) rounded articular facet on palatine; (vi) weakly expressed dorsal crest on cleithrum.
Description.—The posterior part of the parasphenoid and the dorsal medial crest are extended caudally (Fig. 5G). The broad anterior medial crest is well developed. There is a dorsally directed process at the base of the posterior crest. The bone is wide (6.0 mm in the medial part and 7.8 mm in the posterior part). Two shallow longitudinal grooves are expressed in the medial part of the ventral side of the bone. There is a large angle between the postcarotid crests.
The dentaries (Fig. 5E, F) are low, with a uniserial dentition of depressible teeth near the symphysis and a narrow dental shelf. Width of the dentary near the symphysis of these bones from Medzhibozh is 1.2–2.9 mm M 1.5 mm); height of dentary symphysis, 1.9–5.2 mm (M 3.1 mm); and width of tooth row, 1.0– 3.1 mm (M 1.9 mm). Dentaries from Semibalka 1 are comparable in size: width of the dentary near the symphysis, 2.2 and 3.0 mm; height of dentary symphysis, 3.8 and 5.6 mm; width of tooth row, 1.6 and 2.0 mm.
The palatine has a rounded fossa articularis and an uvular articular process (Fig. 5B, C). The dentigerous surface is relatively long and concave. There are C-shaped bases from five rows of small depressible teeth on the ventral surface of the bone (the largest of them located in the medial row). The width of the palatine from Semibalka 1 is 7.0 mm, with DFA 3.5 mm.
Cleithra are represented by their caudal parts (Fig. 5A, D). The thickened dorsal crest is weakly expressed. The width of the plate is 6.2 mm for those from Nova Etuliya and 7.2 mm for the cleithrum from Sinyaya Balka.
Remarks.—All described bones are indistinguishable in morphology and size from those of Esox lucius.
Stratigraphic and geographic range.—Early Pleistocene– Recent, Eurasia and North America.

description: Subgenus Stenotricondyla Naviaux, 2002
Type species. Tricondyla cyanipes Eschscholtz, 1829
Pseudotricondyla Naviaux, 2002, syn. nov.
Differential diagnosis. Aedeagus strongly inflated immediately after basal orifice (Figs 117–129). Endophallus is characterized by presence of a thin appendix, which is located from the left side at the base of ventro-basal (VB) protuberance. In addition, all species of the subgenus have a similar general endophallus shape, i.e., protuberances: VB relatively small; pair of laterally protruding BL; DB relatively large and biforked at apex; elongated median part of endophallus; V small, usually directed towards the apex of endophallus; VA relatively large, often directed towards the base of endophallus, and overlap with V; A often transverse, or with 2–3 apices; DA long; flagellum long and thin. Interocular cavity often narrower and more convex in females. Based on the similarity of the structure of endophallus, we propose a new synonymy Pseudotricondyla Naviaux, 2002, syn. nov. = Stenotricondyla Naviaux, 2002.
Comments. Pseudotricondyla was described by Naviaux (2002) for the species with interocular cavity higher than neck and with transverse constriction behind eyes. Our study of extensive material made it possible to establish that these characters vary narrowly from species to species. In addition, they are variable even within the same species. However, the study of the structure of aedeagus and the endophallus made it possible to identify a large group of species that have a common type of structure. We assign the name Stenotricondyla to this group. Based on the similarity of the structure of endophallus, we propose a new synonymy Pseudotricondyla Naviaux, 2002, syn. nov. = Stenotricondyla Naviaux, 2002.

TONNOIR & EDWARDS 1927: 799, FREEMAN 1951: 28, COLLESS 1963: 303, JASCHHOF & HIPPA 2003.
Four named species of the genus Ohakunea occur in the Australasian region (New Guinea, Australia, New Zealand) and one species in the southern Neotropical region. Additionally, we know of a presumably unnamed species, of which only females have been found so far, present in New Caledonia. Intrageneric relationships of Ohakunea were discussed by JASCHHOF & HIPPA (2003).
Previously overlooked, the tarsi of Ohakunea spp. bear setiform sensilla that are randomly distributed and perpendicular to the surface so that they stick out from the tarsal vestiture. They are presumably homologous to the sensilla described for Colonomyia spp., which however are arranged in-line and occur only on basitarsi (HIPPA & JASCHHOF 2004). The first antennal flagellomeres of Ohakunea spp. bear subbasally a few socketed setae (e. g. up to 8 in australiensis), which was not previously reported.

description: The dichromatic number and the diachromatic number are generalizations of the chromatic number and the achromatic number for digraphs considering acyclic colorings. In this paper, we determine the diachromatic number of digraphs arising from the Zykov sum of digraphs that admit a complete $k$-coloring with $k=\tfrac{1+\sqrt{1+4m}}{2}$ for a suitable $m$. Consequently, the diachromatic number equals the harmonious number for every digraph in this family. In particular, we study the chromatic number, the diachromatic number, and the harmonious chromatic number of the Zykov sum of cycles.
