description: We study the joint distribution of values of a pair consisting of a quadratic form $q$ and a linear form $\mathbf l$ over the set of integral vectors, a problem initiated by Dani-Margulis (1989). In the spirit of the celebrated theorem of Eskin, Margulis and Mozes on the quantitative version of the Oppenheim conjecture, we show that if $n \ge 5$ then under the assumptions that for every $(α, β) \in \mathbb R^2 \setminus \{ (0,0) \}$, the form $αq + β\mathbf l^2$ is irrational and that the signature of the restriction of $q$ to the kernel of $\mathbf l$ is $(p, n-1-p)$, where $3\le p \le n-2$, the number of vectors $v \in \mathbb Z^n$ for which $\|v\| < T$, $a < q(v) < b$ and $c< \mathbf l(v) < d$ is asymptotically
 $$
 C(q, \mathbf l)(d-c)(b-a)T^{n-3} ,
 $$ as $T \to \infty$, where $C(q, \mathbf l)$ only depends on $q$ and $\mathbf l$. The density of the set of joint values of $(q, \mathbf l)$ under the same assumptions is shown by Gorodnik (2004).

(Fig. 11)
Material examined. Two specimens, both from Dam Ngoai; ICHUM 5371 (holotype); ICHUM 5372 (paratype).
Description. Body length 2.5 mm (paratype) to 4.0 mm (holotype), width 0.1 mm (paratype) to 0.2 mm (holotype) (n =2). Epidermis whitish (Fig. 11A); cephalic furrow postcerebrally; tissues around brain (and even in precerebral region in one of two specimens examined) reddish (Fig. 11B, C); cirri present in both anterior and posterior ends of body; cephalic cirrus formula (cf. Norenburg 1988b) observed in two specimens: A=2, B=0, C=8, D=?, E=?, tail= 12 in holotype; A=2, B=0, C=5+6, D=6+10, E=3, tail= 10 in paratype. Foregut–intestine junction indistinct. Statolith polygranular (Fig. 11D, E), 9.5 µm in diameter (n =2), consisting of 6 granules; statocyst 23.5 µm (holotype) to 28.4 µm (paratype) in diameter (n =2). Proboscis anterior chamber with wart-like papillae (Fig. 11F); diaphragm short (Fig. 11F); gland secretion ring situated posterior to hind end of basis; accessory-stylet pouches two, each containing 2–3 accessory stylets directing both forward and backward; central stylet (as well as accessory stylets) spiral (Fig. 11G, H), 35.0 µm (paratype) to 40.2 µm (holotype) long; basis 37.1 µm (paratype) to 40.2 µm (holotype) long, 8.3 µm (paratype) to 11.2 µm (holotype) wide (n =2), with each ridge twisting 3 times; basis length/width ratio 3.59 (holotype) to 4.47 (paratype); middle chamber bulbous (Fig. 11F); posterior chamber opaque, with specialized anterior part (Fig. 11B, C). Intestinal diverticula deep. Posterior adhesive plate containing cells with orange contents.
Distribution. So far only recorded from the type locality, Dam Ngoai, Vietnam.
Etymology. The specific name is a noun in the genitive case, after the Japanese ostracode systematist Professor Akira Tsukagoshi at Shizuoka University, Japan, who organized our sampling trip to Phu Quoc.
Remarks. In the phylogenetic tree, Ototyphlonemertes (parmula) tsukagoshii sp. nov. was sister to O. (parmula) nakaoae sp. nov. (Fig. 2). Ototyphlonemertes (parmula) tsukagoshii differs from O. (parmula) nakaoae by the smaller body length (2.5–4.0 mm vs. 4.1–6.2 mm), fewer number of statolith granules (6 vs. 7–8), and greater number of styletridge twists (3 vs. 1.5–2). Also, O. (parmula) tsukagoshii tends to be more reddish in the external appearance, especially in the brain region, than O. (parmula) nakaoae.

description: Family Ptychogastriidae Mayer, 1910
Diagnosis
Trachymedusae with either Fat or dome-shaped umbrella; with four-lobed manubrium, not giving rise to mesenteries, or with eight-lobed manubrium, giving rise to eight mesenterial partitions of the subumbrella; without gastric peduncle; mouth with four simple lips; tentacles marginal, either Fliform, not arranged in groups and inserted at varied levels on the umbrellar margin, or Fliform and adhesive occurring simultaneously, and grouped into more or less well-deFned clusters composed of several superimposed rows; eight radial canals joining the circular canal; centripetal canals either absent or present; gonads either simple, elongated and attached to the body of manubrium, or in pairs resulting from the mesenterial partitions and developing on either side of the manubrial lobes; with or without a velum; with either 8 or 16 free, ecto-endodermal statocysts.
Remarks
Earlier diagnoses (Mayer 1910; Kramp 1959, 1961, 1968; Bouillon & Boero 2000; Bouillon et al. 2006) are broadened by taking into consideration the shape of the umbrella, the presence/absence of a velum, and of centripetal canals. Indeed, unlike both Ptychogastria Allman, 1878 and Tesserogastria Beyer, 1959, the medusae belonging to the so far monotypic genus Glaciambulata gen. nov. (see below) have Fattened rather than dome-shaped umbrellas, and they also lack a velum. The presence of centripetal canals was curiously excluded from earlier diagnoses of the family, though they are present in P. polaris Allman, 1878. The occurrence of the gonads is henceforth restricted to the manubrium only, because Pectis antarctica Haeckel, 1879, formerly assigned to the genus Ptychogastria by a number of authors, has the gonads on the radial canals and, for this reason, combined with additional characters, does not belong to Ptychogastriidae (see below).
The main distinguishing characters of ptychogastriid genera are listed in Table 1.

description: We consider the community detection problem in sparse random hypergraphs under the non-uniform hypergraph stochastic block model (HSBM), a general model of random networks with community structure and higher-order interactions. When the random hypergraph has bounded expected degrees, we provide a spectral algorithm that outputs a partition with at least a $γ$ fraction of the vertices classified correctly, where $γ\in (0.5,1)$ depends on the signal-to-noise ratio (SNR) of the model. When the SNR grows slowly as the number of vertices goes to infinity, our algorithm achieves weak consistency, which improves the previous results in Ghoshdastidar and Dukkipati (2017) for non-uniform HSBMs.
 Our spectral algorithm consists of three major steps: (1) Hyperedge selection: select hyperedges of certain sizes to provide the maximal signal-to-noise ratio for the induced sub-hypergraph; (2) Spectral partition: construct a regularized adjacency matrix and obtain an approximate partition based on singular vectors; (3) Correction and merging: incorporate the hyperedge information from adjacency tensors to upgrade the error rate guarantee. The theoretical analysis of our algorithm relies on the concentration and regularization of the adjacency matrix for sparse non-uniform random hypergraphs, which can be of independent interest.

Type:— BRAZIL. “Habitat in silvis ad villam Ega in prov. do alto Amazonas”, Pöppig 3109 (syntypes: P [01902445], image, G [00223425], image, BM [000953773], image). (Fig 3 AB)
Shrubs ca. 1.5 m. Twigs glabrous. Leaves with petioles 9–10 mm long, glabrous, unchanneled or shallowly channeled; blades elliptic, oblong, or oval, 10–12.1 × 3.6–5.1 cm, glabrous, chartaceous, discolorous; glands not seen; base cuneate or rounded; apex acute, cuneate, rarely rounded; midvein adaxially flat; lateral veins visible, not arched, 10 to 15 pairs; intra-marginal vein 1–3 mm from the margin, margin revolute. Inflorescence axillary, a fascicle, the axis 1–2 mm, glabrescent; bracts orbicular, 0.5 × 0.5 mm, glabrous, persistent in the fruit; pedicels 4–9 mm long, glabrous; bracteoles ovate, 1.5 × 1 mm, glabrous, persistent in the fruit; flower buds globose, 3–4 × 5–6 mm, not constricted above ovary; calyx-lobes free, four, orbicular, 1.4–2 × 1–2 mm, glabrous, not reflexed, persistent in the fruit; ovary not seen. Immature fruit globose, ca. 1 cm diameter, glabrous, surface smooth.
Note:— E. dittocrepis may be recognized by its leaves, which are green-yellowish adaxially and reddish-brown abaxially in the dried material, with revolute margins; its inflorescence, which is a glabrescent fascicle with persistent bracteoles in fruit; and its globose, glabrous, and smooth fruit. This species is morphologically related to E. stictopetala but can be distinguished by its revolute leaf margins (vs. flat) and its discolorous leaves (vs. concolorous leaves).
Distribution and habitat:— Known from Colombia, Ecuador, Peru, Venezuela and northeastern and northwestern Brazil (Acre, Amazonas, Maranhão, Mato Grosso and Pará states) (POWO 2020, Flora do Brasil 2020). In Amazonian Maranhão, E. dittocrepis was found growing along waterways.
Phenology:— Fruiting in April.
Specimens examined:— BRAZIL. Maranhão: Cândido Mendes, Maracassumé River Region, 30 April 1932 (fr.), R.L. Fróes 1709 (NY!). Viana, 1958 (st.), O. Carvalho 5 (RB, image).

description: We prove vanishing results for the coherent cohomology of the good reduction modulo $p$ of the Siegel variety with coefficients in some automorphic bundles. We show that for an automorphic bundle with highest weight $λ$ near the walls of the anti-dominant Weyl chamber, there is an integer $e \geq 0$ such that the cohomology is concentrated in degrees $[0, e]$. The accessible weights with our method are not necessarily regular and not necessarily $p$-small. Since our method is technical, we also provide an algorithm written in Sage that computes explicitly the vanishing results.

Fig. 16
Diagnosis. The palpal organ of this species is very similar to that of the Oriental Hyllus diardi (Walckenaer, 1837), but it has a tibial apophysis with a bifurcated tip, whereas H. diardi has an apophysis with single blunt tip (compare Fig. 16E with Żabka 1985: fig. 223). Female unknown.
Etymology. The specific epithet is the Latin word meaning “forked” and refers to the shape of the tibial apophysis.
Type material. Holotype: 1♂, MOZAMBIQUE: Tete: IV.1947, leg. C.F. Roewer (SMF 9905).
Paratypes: MOZAMBIQUE: Tete: no further details, 1♂ (SMF 9702), 1♂ (SMF 9685).
Other material. TANZANIA: Usambara Mountains, no further details, 1♂ (SMF).
Description. Male: Measurements: Cephalothorax: length 6.3, width 5.1, height 4.1. Eye field: length 2.4, anterior and posterior width 3.1. Abdomen: length 6.1, width 3.4. General appearance in Fig. 16A. Carapace rounded, reddish-brown, eyes encircled by black rings. Some long bristles on carapace. Clypeus and frontal surfaces of chelicerae with dense long colourless hairs. Sternum light brown, labium and endites darker with whitish tips. Abdomen elongate, narrower than carapace, reddish-brown, with sparse long bristles, denser at anterior edge. Venter light brown with two lines formed by white dots. Spinnerets brown, hairy. Legs dark brown, bearing very dense brown and colourless hairs, especially dense on legs I and II. Palps small, dark brown, with dense hairs. Tibial apophysis short, forked at the top (Fig. 16C, E). Bulb oval, with small posterior lobe, embolus accompanied by pars pendula (Fig. 16B, D).
Distribution. Northwestern Mozambique and northeastern Tanzania.
Remark. There are numerous African Hyllus C.L. Koch, 1846 that are only known from females that could potentially be a match to this species, but this can only be assessed once specimens are collected from the same locality.

Lycosa

description: Genus Lycosa Latreille, 1804
Type species. Aranea tarantula Rossi, 1790
Diagnosis. According to the identification key proposed by Logunov (2010), Lycosa differs from other large central Asian burrowing wolf spiders in the following characters: (1) hooked-shaped median apophysis; (2) singular synembolus; (3) epigyne comprising an anterior elevation (4) absence of epigynal depression, (5) distinct septal pedicle; (4) relatively complex spermathecae with long and S-shaped ducts.
Comments. Spiders of the genus Lycosa are relatively large and fossorial. The genus includes 224 species distributed worldwide, with the highest species diversity in Asia and South America (World Spider Catalog 2022). Five species have been recorded from Iran, including two endemic species (L. aragogi Nadolny & Zamani, 2017 and L. macrophthalma Nadolny & Zamani, 2020), which were described from the females (World Spider Catalog 2022) and hence can be compared to the new species being described in the present paper based on the similarities in copulatory organs (see Lycosa soboutii sp. n.). Also, the new species is assigned to the genus Lycosa according to the similarities of habitus and epigyne: large spiders with septal pedicle, massive folds at vulva, not anchor-shaped septum and the absence of epigynal depression.

description: The nonleptonic weak decay processes $Ω_c \to Ωπ^+/Ω(1P)π^+/Ω(1D)π^+/Ω(2S)π^+$ are studied using the constituent quark model. The branching fraction of $Ω_c \to Ωπ^+$ is predicted to be $1.0\%$. Considering the newly observed $Ω(2012)$ resonance as a conventional $1P$-wave $Ω$ excite state with spin-parity $J^P=3/2^-$, the newly measured ratio $\mathcal{B}[Ω_c\to Ω(2012)π^+ \to (Ξ\bar{K})^-π^+ ]/\mathcal{B}[Ω_c\to Ωπ^+]$ at Belle can be well understood. Besides, the production rates for the missing $1P-$wave state $Ω(1^2P_{1/2^-})$, two spin quartet $1D-$wave states $Ω(1^4D_{1/2^+})$ and $Ω(1^4D_{3/2^+})$, and two $2S$-wave states $Ω(2^2S_{1/2^+})$ and $Ω(2^4S_{3/2^+})$ are also investigated. It is expected that these missing excited $Ω$ baryons should have large potentials to be discovered through the nonleptonic weak decays of $Ω_c$ in forthcoming experiments by Belle II and/or LHCb.

urn:lsid:zoobank.org:act:B2696364-D58F-4BB9-B326-DE244E1FA51A
Type species
Glaciambulata neumayeri gen. et sp. nov.
Diagnosis
Crawling medusae, unable to swim, possibly due to the absence of a velum. Umbrella watch glassshaped, margin entire, not lobed; exumbrella smooth; eight radial canals joining a circular canal; centripetal canals absent; manubrium eight-lobed, giving rise to eight perradial mesenteries; eight pairs of gonads, each of which is conFned to either side of a manubrial lobe; tentacles of two types, Fliform and adhesive, arranged in contiguous groups composed of several superimposed rows; 16 free, ectoendodermal statocysts (2 per octant).
Etymology
From the Latin words glăciēs, meaning ice, and ambŭlo, -āvī, -ātum, -āre, meaning to walk, making reference to the peculiar habit of this medusa.
Remarks
The Fat, smooth umbrella, and the absence of a velum immediately distinguish the new genus from Ptychogastria Allman, 1878 and Tesserogastria Beyer, 1959. The manubrial shape, the composition and arrangement of tentacles, the presence of mesenteries, and the shape and position of the gonads, are reminiscent of Ptychogastria. The presence of adhesive tentacles, and of 16 statocysts, instead of only 8, further distinguish it from Tesserogastria.

description: The evolution of autonomous ships marks a significant stride in maritime operations, promising applications across a wide range of industries. These innovations enhance shipping and marine operations by improving safety through the reduction of human error and by enhancing the quality of life for mariners by alleviating tedious or difficult workloads. Whether in commercial shipping, passenger transport, or scientific research, autonomous ships are set to revolutionize the way we navigate the seas, making maritime activities more efficient and safer. Central to advancing this domain is the precise trajectory tracking of Autonomous Surface Vessels (ASVs), which is vital for their safe and efficient navigation. It is simultaneously required to operate within specified timeframes while adhering to maritime regulations and safely maneuvering amidst dynamic marine conditions such as waves, currents, and winds, which pose formidable technical challenges to autonomous trajectory tracking. Presently, both model-based and data-driven controllers are pivotal in navigating Autonomous Vessels, emphasizing the critical need for accuracy and reliability in trajectory following. However, achieving precise trajectory tracking under real-world conditions remains intricate due to varying ship dynamics and environmental disturbances, necessitating tailored controller designs. In this study, our principal aim is to develop a controller that comprehensively addresses these challenges while upholding safety constraints. We leverage Nonlinear Model Predictive Control (NMPC) for its suitability in handling nonlinear ship models, accommodating unmodeled dynamics, managing diverse constraints, and ensuring course stability amidst multivariable systems. An Unscented Kalman Filter (UKF) is integrated with NMPC to mitigate wave-induced disturbances and enhance robustness. Our NMPC controller with UKF, implemented with mechanistic and Neural Network (NN) ship models, is evaluated through trajectory tracking simulations and experimental trials using the Magne Viking ship model at the National Research Council (NRC) in Canada. Incorporating an Artificial Neural Network captures intricate ship dynamics, exhibiting promising results in simulations and practical experiments. We compare the performances of mechanistic and NN models to validate their efficacy, proposing further enhancements through deep neural network training with natural data. Integrating NMPC with neural network structures represents a core aspect of this research, aiming to advance autonomous ship trajectory tracking capabilities in real-world scenarios.

description: Let $X$ be a K3 surface over a number field. We prove that $X$ has infinitely many specializations where its Picard rank jumps, hence extending our previous work with Shankar--Shankar--Tang to the case where $X$ might have potentially bad reduction. We prove a similar result for generically ordinary non-isotrivial families of K3 surfaces over curves over $\overline{\mathbb{F}}_p$ which extends previous work of Maulik--Shankar--Tang. As a consequence, we give a new proof of the ordinary Hecke orbit conjecture for orthogonal and unitary Shimura varieties.

Pectyllis – Haeckel 1881a: 9; 1881b: 10.
Pectanthis – Haeckel 1881a: 17; 1881b: 19.
Diagnosis
Crawling ptychogastriid medusae with swimming capabilities; with dome-shaped, marginally-“lobed” umbrella, and eight-lobed manubrium, giving rise to as many mesenterial partitions of the subumbrellar cavity; mouth quadrangular, with simple lips; eight radial canals; centripetal canals either present or absent; eight pairs of gonads conFned to the sides of the manubrial lobes; tentacles Fliform and adhesive, occurring simultaneously and arranged in clusters around the bell margin; velum broad; 16 free, ectoendodermal statocysts (2 per octant).
Remarks
The diagnoses given by Bouillon & Boero (2000) and Bouillon et al. (2006) are broadened again, so as to include the shape of the umbrella, the presence/absence of centripetal canals, and the presence of a velum, as Allman (1878) and/or Mayer (1910) did earlier.
As underlined by Mayer, the «differences between the genera “ Pectyllis,” “ Pectis,” and “ Pectanthis,” as deFned by Haeckel, are so slight as to appear of speciFc rather than of generic value». Indeed, Haeckel (1879) distinguished Pectis (type species Pectis antarctica) from both Pectanthis (type species Pectanthis asteroides) and Pectyllis (type species Pectyllis arctica) through the presence of centripetal canals. In contrast, the tentacles were described as arranged in distinct groups in Pectanthis, and forming comparatively more contiguous groups in both Pectis and Pectyllis.
Similarly, Browne (1903) acknowledged earlier that “When Pectis antarctica and Pectanthis asteroides have been again examined it may be found that one genus with three species will be quite sufFcient”. However, it will be shown at the end of this paper that the former species does not belong to Ptychogastriidae, but to a different family of Trachymedusae, viz. Rhopalonematidae Russell, 1953.

description: We theoretically investigate exciton-polaritons in a two-dimensional (2D) semiconductor heterostructure, where a static magnetic field is applied perpendicular to the plane. To explore the interplay between magnetic field and a strong light-matter coupling, we employ a fully microscopic theory that explicitly incorporates electrons, holes and photons in a semiconductor microcavity. Furthermore, we exploit a mapping between the 2D harmonic oscillator and the 2D hydrogen atom that allows us to efficiently solve the problem numerically for the entire Rydberg series as well as for the ground-state exciton. In contrast to previous approaches, we can readily obtain the real-space exciton wave functions and we show how they shrink in size with increasing magnetic field, which mirrors their increasing interaction energy and oscillator strength. We compare our theory with recent experiments on exciton-polaritons in GaAs heterostructures in an external magnetic field and we find excellent agreement with the measured polariton energies. Crucially, we are able to capture the observed light-induced changes to the exciton in the regime of very strong light-matter coupling where a perturbative coupled oscillator description breaks down. Our work can guide future experimental efforts to engineer and control Rydberg excitons and exciton-polaritons in a range of 2D materials.

description: Contemporary planning practice is often criticized as too design-driven with a lack of both quantitative evaluation criteria and employment of models that anticipate the self-organizational forces shaping cities, resulting in significant gaps between plan and reality. This study aims to introduce a modular toolbox prototype for spatial-analysis in data-poor environments. It is proposed to integrate designing, evaluation, and monitoring of urban development into one framework, thus supporting data-driven, on-demand urban design, and planning processes. The proposed framework’s value will exemplarily be tested, focussing on the analysis and simulation of spatiotemporal growth trajectories taking the Lanzhou New Area as a case-study - a large scale new town project that struggles to attract residents and businesses. Conducted analysis suggests that more attention should be given to spatiotemporal development paths to ensure that cities work more efficiently throughout any stage of development. Finally, early hints on general design strategies to achieve this goal are discussed with the assistance of the proposed toolbox.
