kpoinar/moulin-physical-model: Moulin Shape model for The Cryosphere article, 2022
No full textNearly all meltwater from glaciers and ice sheets is routed englacially through moulins. Therefore, the geometry and evolution of moulins has the potential to influence subglacial water pressure variations, ice motion, and the runoff hydrograph delivered to the ocean. We develop the Moulin Shape (MouSh) model, a time-evolving model of moulin geometry. MouSh models ice deformation around a moulin using both viscous and elastic rheologies and melting within the moulin through heat dissipation from turbulent water flow, both above and below the water line. We force MouSh with idealized and realistic surface melt inputs. Our results show that variations in surface melt change the geometry of a moulin by approximately 20% daily and by over 100% seasonally. These size variations cause observable differences in moulin water storage capacity, moulin water levels, and subglacial channel size compared to a static, cylindrical moulin. Our results suggest that moulins are important storage reservoirs for meltwater, with storage capacity and water levels varying over multiple timescales. Implementing realistic moulin geometry within subglacial hydrologic models would therefore improve the representation of subglacial pressures, especially over seasonal periods or in regions where overburden pressures are high

Cost Sharing, Differential Games, and the Moulin-Shenker Rule
No full textThe Moulin-Shenker rule (Sprumont (1998)) is a nonlinear solution concept for solving heterogeneous cost sharing problems. The first part of the paper shows an axiomatic characterization of this solution using bounds on cost shares and consistency. The second part is devoted to differential games for heterogeneous production problems. It is shown for 2-player games that by an appropriate choice of the game dynamics there is essentially a unique Markov perfect Nash equilibrium. An axiomatic analysis follows for the appropriate game dynamics, which leads in turn to a strategic characterization of the Moulin-Shenker rule.

Same coloration as head and pronotum. Coxae rectangular, trapezoid in cross-section, with one or two stronger tubercles among scattered smaller tubercles on posteroventral side, and 15-18 very small dorsal spines of inequal size; anterior side with numerous pale spots. Trochanter slightly granular. Femora triangular in cross-section, spotted, with 6 posteroventral spines; margin between spines crenelated; dorsal margin almost smooth, with an indistinct lobe at base; 16 anteroventral spines, and 4 discoidal spines, large anteroventral spines with a dark spot around base. AvS configuration IiiIiIiIiIiIiIiI. Claw-groove at basal fourth of femur.Tibiae dark brown, spotted with pale; 24-25 decumbent, rather small posteroventral spines; 18 anteroventral spines; first tarsomere longer than remaining tarsomeres together. Meso- and metathoracic legs.Typical for the group.All segments setose. Coxae robust, relatively long. Femora slightly widened, with a deeply concave ventral margin, accommodating tibia when at rest; genicular lobes triangular. Tibiae slightly arched, mesothoracic tibiae indistinctly swollen in the basal half, metathoracic tibiae for almost two thirds of their length, with a very short apical lobe and two proximally black terminal spines; tarsi with first tarsomere shorter than next four taken together. Wings (Fig. 17). Forewings opaque, brown, resembling dry leaves, with the postero-apical region subopaque; costal field widest at about first quarter of wing, then tapering towards apex; forewing without subapical and apical lobes; stigma irregularly shaped, opaque, shiny.

Supraanal plate deeply indented, bearing short 9-segmented cerci, first and last segment consisting of 3 and 2 fused segments, respectively. Apex of last segment flattened and indented (Fig. 18A), with the two lobes of roughly the same size. Sternites each with a median and two paramedian lobes at posterior margin.

Left phallomere with a simple, sclerotized afa. Membranous lobe indistinctly setose, not well developed. Apical process digitiform, curved at the end. Right phallomere as in related species. REMARKS The holotype male is in relatively good condition, given its age and history. Pronotum, right femur, right hind leg, and abdomen are glued to the specimen, the latter with the ventral side up. The right forewing is also slightly damaged, and the antennae are missing. However, most taxonomically significant parts are still present. Female Unknown. DIFFERENTIAL DIAGNOSES Royacanthops n. gen., Plesiacanthops, Miracanthops and Parvacanthops Schwarz & Moulin, n. gen. are hypothesized here to represent a monophyletic unit. They are distinguished from other acanthopines by the following combination of characters: prominent juxtaocular bulges; metazona elongate, with parallel margins, in males with a distinct expansion along its length; weakly developed anterior lobe on forefemora; genicular lobes of walking leg femora short in males, more or less elongate in females; abdominal sternites with three posterior projections; and very long, sinuate sdp re-curved to the left (in Parvacanthops Schwarz & Moulin, n. gen. the sdp is ellipsoid and curved dorso-dextrad, but the tip is slightly sinuate; we argue in favor of this condition being secondarily derived from the sinuate condition by an anterodorsal rotation of the sdp apex). The sinuate sdp, along with the lobate posterior margin of the female tegmen, is shared with Acanthops erosula Stål, 1877, which is closely related to this generic group (i.e., Plesiacanthops, Miracanthops, Parvacanthops Schwarz & Moulin, n. gen., and Royacanthops n. gen.). Acanthops erosula can be distinguished from other Acanthops by a more elongate metazona (though not as long as in Plesiacanthops, Miracanthops, Parvacanthops Schwarz & Moulin, n. gen., and Royacanthops n. gen.), and the posteriorly lobate tegmen apex in females. The latter character is also found in Pseudacanthops Saussure, 1870, but not in other Acanthops, Decimiana, Metilia, or Metacanthops. Acanthops erosula shares with Royacanthops n. gen. the subapical lobe on the male tegmina and the large, bilobed loa which curves dorsally around afa. Both characters are reduced in Plesiacanthops, Miracanthops (Schwarz & Roy 2018) and Parvacanthops Schwarz & Moulin, n. gen. The three genera are further distinguished from Royacanthops n. gen. in the male sex by their tegmina lacking a subapical lobe, and the alae being distinctly longer than the tegmina. In Royacanthops n. gen. the alae are shorter than the tegmina. Females of Royacanthops n. gen. share with those of Plesiacanthops the shape of the tegmina, while having a slightly wider costal field. They share with Miracanthops the very large juxtaocular bulges. They are distinguished from Plesiacanthops and Miracanthops by fewer but larger teeth along the metazona, and by the very large abdominal lobes. Females of Plesiacanthops are distinguished from those of Miracanthops by smaller juxtaocular bulges and thus a more convex vertex, and by much less elongate female tegmina. Males of Plesiacanthops and Parvacanthops Schwarz & Moulin, n. gen. are distinguished from those of Miracanthops by less elongate male hindwings without a distinct apical truncation, and the smaller, only slightly widened last segment of the cerci. Males of Plesiacanthops are distinguished from those of Miracanthops and Parvacanthops Schwarz & Moulin, n. gen. by a more sinuate costal field and the presence of elongate setae at the basis of loa in the left phallomere. Parvacanthops Schwarz & Moulin, n. gen. shares with Miracanthops the small indistinct lobe on the prothoracic femur, the shape of the coastal field and of the ventral phallomere, and the simplified afa surrounded by a moderately developed loa. It is distinguished from Miracanthops by smaller body size, the convex vertex with its quadricuspidate process and the differently shaped eyes, the reduced lateral expansion along the metazona, smaller tergal lobes on the abdomen, the shape of the last cercal segment, and a differently shaped hindwing apex.Femoral PvS are six in Parvacanthops Schwarz & Moulin, n. gen. and Royacanthops n. gen. vs seven in Plesiacanthops, while Miracanthops exhibits both character states.Published as part of Moulin, Nicolas & Schwarz, Christian J., 2023, Two new genera of Acanthopidae (Mantodea) from the Amazon region, with description of a new species, pp. 137-161 in Zoosystema 45 (5) on pages 152-155, DOI: 10.5252/zoosystema2023v45a5, http://zenodo.org/record/772880
