(Figs 11, 16 K, 18C, 20C)
Material examined. New Zealand Antarctic Expedition TAN0402: Stn 88, Tangaroa, 14 February 2004, 72°05'86''S, 172°55'81''E (Cape Adare, Ross Sea), 515 m.
Description. Monosiphonic, usually unbranched stems, up to 210 mm high, usually divided into internodes. Angle between cauline apophyses and stem 70–90°. Perisarc strongly developed. Cauline apophyses with two axillary nematophores, each emerging through simple perisarc holes (Fig. 11 B–C).
Hydrocladia typically bifurcated (Fig. 11 A), but up to third-order branching present. First hydrocladial internode bifurcated, with two similar prongs (Fig. 11 B). Mesial inferior nematophore emerging from marked swelling at proximal third of internode (Fig. 11 D); with strongly developed nematotheca (Fig. 11 D, F). Hydrotheca elongate, roughly placed on middle of internode. Stony appearance. Abcauline wall straight, but convex at basal part. Hydrothecal aperture circular, roughly perpendicular to long axis of internode (Fig. 11 D–E, G); rim typically uneven, with slight adcauline elevation.
Gonothecae elongated with large subterminal aperture.
Remarks. The most striking feature of O. rigida is the strong stony appearance under SEM.
We have observed two axillary nematophores on every cauline apophysis examined (Fig. 11 B–C). Nevertheless, Peña Cantero et al. (1997) indicated that apophyses with a single axillary nematophore were also present. In this sense, it is worth mentioning that we have also observed a tendency to fusion of the two axillary nematophores.

description: Gradient descent prevails in artificial neural network training, but seems inept for spiking neural networks as small parameter changes can cause sudden, disruptive (dis-)appearances of spikes. Here, we demonstrate exact gradient descent based on continuously changing spiking dynamics. These are generated by neuron models whose spikes vanish and appear at the end of a trial, where it cannot influence subsequent dynamics. This also enables gradient-based spike addition and removal. We illustrate our scheme with various tasks and setups, including recurrent and deep, initially silent networks.

Abdomen ovate, covered with a very fine silky pile, and with a large ovate cream-coloured spot on each side at the base.
Hab. Adelaide.
Of this very conspicuous and beautiful species I have only seen the single specimen described: in the form of the thorax it differs from the majority of species, being somewhat flattened above, the margins raised and crenulated, the anterior margin rounded in the middle and curving on each side, forming a lateral, sharp, angular tooth; the division between the meso- and metathorax is very distinctly impressed.

Quantum Entanglement Phase Transitions and Computational Complexity: Insights from Ising Models

description: In this paper, we construct 2-dimensional bipartite cluster states and perform single-qubit measurements on the bulk qubits. We explore the entanglement scaling of the unmeasured 1-dimensional boundary state and show that under certain conditions, the boundary state can undergo a volume-law to an area-law entanglement transition driven by variations in the measurement angle. We bridge this boundary state entanglement transition and the measurement-induced phase transition in the non-unitary 1+1-dimensional circuit via the transfer matrix method. We also explore the application of this entanglement transition on the computational complexity problems. Specifically, we establish a relation between the boundary state entanglement transition and the sampling complexity of the bipartite $2$d cluster state, which is directly related to the computational complexity of the corresponding Ising partition function with complex parameters. By examining the boundary state entanglement scaling, we numerically identify the parameter regime for which the $2$d quantum state can be efficiently sampled, which indicates that the Ising partition function can be evaluated efficiently in such a region.

Material examined. Spanish Antarctic Expedition Bentart 2006: Stn Low 45, Hespérides, February 2006, 63.43171°S, 62.2116°W (Low Island, Antarctic Peninsula), 86 m (Department of Zoology, University of Valencia, BENTART 2006—LOW 45).
Description. Polysiphonic, unbranched stems, up to 170 mm high, divided into internodes. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with four nematophores: two axillary ones, each emerging through simple hole in perisarc, and two other nematophores, each emerging through a strongly developed ‘mamelon’ (Fig. 12 B).
Hydrocladia much branched (Fig. 12 A), with up to fourth-order hydrocladia. First hydrocladial internode bifurcated, with two similar prongs (Fig. 12 A). End of distal internodes peak-shaped (Fig. 12 A, E). Mesial inferior nematophore emerging from very strongly marked swelling at proximal third of internode (Fig. 12 C–E); without nematotheca (Fig. 12 C–E). Hydrotheca elongate, placed on middle of internode. Abcauline wall convex at distal part. Free part of adcauline wall much separated from internode (Fig. 12 D). Mesial superior nematophore arising at axil between internode and free part of adcauline wall (Fig. 12 D). Hydrothecal aperture kidney-shaped (Fig. 12 D), adcaudally directed; free part of adcauline wall strongly directed inwards (Fig. 12 D).
Gonothecae pear-shaped, with distal, large, circular aperture; female gonotheca (Fig. 12 F) much larger than male one.
Remarks. Cauline apophyses with a single ‘mamelon’ have also been reported (cf. Peña Cantero & Vervoort 2004). The relatively large size of the aperture of the ‘mamelons’ is noteworthy (Fig. 12 B).

description: We investigate the deconfinement transition driven by excitations in long-range spin models. At low temperatures, these models exhibit a confined phase where domain-wall (or kinks) are localized. As temperature increases, kinks interact and propagate, leading to a transition to a de-confined phase. This transition is influenced by the interplay between thermal energy and interaction effects, resulting in extended, de-confined regions. Although kinks density is dynamically stable, non-equilibrium changes in their fluctuations characterize the transition. Our findings provide insights into the mechanisms of confinement and deconfinement in long-range spin models, with implications for both condensed matter physics and lattice gauge theories. Bridging these fields, this study sheds light on the universal aspects of confinement and opens avenues for further exploration and experimental verification.

Description. Polysiphonic, unbranched stems, up to 500 mm high, usually divided into internodes. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with four to five nematophores, two to three axillary ones, each emerging through simple hole in perisarc, and other two nematophores, each emerging through ‘mamelon’ (Fig. 7 B–C).
Hydrocladia much branched (Fig. 7 A), with up to third-order hydrocladia. First hydrocladial internode bifurcated (Fig. 7 A), with two similar prongs. Mesial-inferior nematophore typically with much reduced nematotheca, though not existent in present material (Fig. 7 D–F). Unforked hydrocladial internodes without infrathecal swelling. Hydrotheca placed on distal half of internode (Fig. 7 D–E). Hydrotheca low, about as high as wide. Abcauline hydrothecal wall straight. Hydrothecal aperture circular, perpendicular to longitudinal axis of internode; rim even (Fig. 7 D–E).
Male gonothecae almost cylindrical, with subterminal opening. Female larger, club-shaped, with subterminal aperture.
Remarks. Peña Cantero & García Carrascosa (1995) did not find any mesial inferior nematothecae when they examined this material, a pattern corroborated herein by SEM analysis. As Peña Cantero & García Carrascosa (1995) indicated, this could be related with the poor condition of the material with just a few hydrocladia left.
Until now only two axillary nematophores in the cauline apophyses had been described for this species. However, we observed three with the central one being larger and sometimes with the appearance of being the result of coalescence of two central ones (Fig. 7 C).

Cauline apophyses with two to six axillary nematophores, each emerging through perisarc hole (Fig. 13 B–C), frequently with very short collar-shaped nematotheca (Fig. 13 B), and with up to two extra nematophores, each emerging through ‘mamelon’ (Fig. 13 B–C).
Hydrocladia much branched (Fig. 13 A), with up to fourth-order hydrocladia. First hydrocladial internode bifurcated, with two similar prongs (Fig. 13 A). Mesial inferior nematophore emerging from marked swelling at proximal third of internode (Fig. 13 D–E); with rudimentary, nail-shaped nematotheca (Fig. 13 F–G). Hydrotheca elongate, placed on middle of internode. Abcauline wall roughly straight. Adcauline wall mostly adnate (Fig. 13 D– E). Hydrothecal aperture circular, perpendicular to longitudinal axis of internode (Fig. 13 E); rim even.
Gonothecae fusiform, with sub-terminal aperture (Fig. 13 H).
Remarks. Oswaldella stepanjantsae is remarkable for the high variability in the number of axillary nematophores in the cauline apophyses. Peña Cantero & Vervoort (2004) reported from two to six. Although we have only observed four, the structure of the central nematophores in some of the cauline apophyses examined seems to indicate that they might have resulted from fusion of the four central nematophores (Fig. 13 C). In addition, although the species typically has two mamelons in the cauline apophyses, sometimes one, or even both, may be absent (Peña Cantero & Vervoort, 2004).
The SEM study has also revealed the, so far unknown, frequent presence of a neck of perisarc in the axillary nematophores of the cauline apophyses (Fig. 13 B).

(Figs 15, 16 P, 18H, 20H)
Material examined. New Zealand Antarctic Expedition TAN0402: Stn 178, Tangaroa, 27 February 2004, 71°31’89’’– 71°32’16’’S, 171°18’31’’– 171°18’70’’E (Cape Adare, Ross Sea), 343– 348 m.
Description. Monosiphonic, unbranched stems, up to 100 mm high, divided into internodes. Cauline apophyses with two axillary nematophores, each emerging through simple hole in perisarc (Fig. 15 B).
Hydrocladia usually bifurcated, first hydrocladial internode giving rise to two secondary hydrocladia; however, a third-order hydrocladium is not uncommon (Fig. 15 A). First hydrocladial internode bifurcated, with two similar prongs (Fig. 15 A). Mesial inferior nematophore emerging from marked swelling at proximal third of internode (Fig. 15 C); with well-developed, claw-shaped nematotheca (Fig. 15 C–E). Hydrotheca low, about as high as wide, placed on distal half of internode. Abcauline wall straight; adcauline one mostly adnate (Fig. 15 C). Hydrothecal aperture circular (Fig. 15 D), roughly perpendicular to longitudinal axis of internode (Fig. 15 C); rim even.
Gonothecae unknown.
Remarks. Our material is undoubtedly conspecific with the material described as Oswaldella sp.2 by Peña Cantero & Vervoort (2004). It is also morphologically very close to Oswaldella incognita (cf. Figs 8, 15), sharing many characteristics with this species (see also Peña Cantero & Vervoort 2004). The number of axillary nematophores, and the absence of 'mamelons', gives to the cauline apophyses of Oswaldella sp. a similar configuration to that found in O. incognita. Additionally, they share the presence of mesial inferior nematotheca, as well as the shape of nematothecae and hydrothecae. Peña Cantero & Vervoort (2004) indicated that Oswaldella sp.2 has longer hydrocladial internodes and shorter hydrothecae and that they also differ in the fact that only secondary hydrocladia had been described for O. incognita. Peña Cantero & Vervoort (2009), however, studied material of O. incognita with occasional presence of third-order hydrocladia. In our opinion, Oswaldella sp. and Oswaldella incognita share so many key features they are likely conspecific, though it would be necessary to examine the material studied by Peña Cantero & Vervoort (2004) to confirm that the axillary nematophores do not have nematothecae.

description: A design optimization framework for process parameters of additive manufacturing based on finite element simulation is proposed. The finite element method uses a coupled thermomechanical model developed for fused deposition modeling from the authors' previous work. Both gradient-based and gradient-free optimization methods are proposed. The gradient-based approach, which solves a PDE-constrained optimization problem, requires sensitivities computed from the fully discretized finite element model. We show the derivation of the sensitivities and apply them in a projected gradient descent algorithm. For the gradient-free approach, we propose two distinct algorithms: a local search algorithm called the method of local variations and a Bayesian optimization algorithm using Gaussian processes. To illustrate the effectiveness and differences of the methods, we provide two-dimensional design optimization examples using all three proposed algorithms.

An α-cut intervals based fuzzy best-Worst method for Multi-Criteria Decision-Making

description: The Best-Worst Method (BWM) is a well-known Multi-Criteria Decision-Making (MCDM) method used to calculate criteria-weights in many real-life applications. It was observed that the decision judgments used to calculate weights in BWM may be imprecise due to human involvement. To incorporate this ambiguity into the weight calculation, Guo & Zhao proposed a model of BWM using fuzzy sets, known as Fuzzy BWM (FBWM). Although this model is known to have wide applicability, it has several limitations. One of the biggest limitations of this existing model is that the lower, modal and upper values of the fuzzy judgment are used in the weight calculation and the other values remain unused. To solve this limitation and optimize the entire shape, we propose a model of FBWM based on α-cut intervals. This helps in reducing information loss. It turns out that although it is possible to optimize the entire shape simultaneously, it is difficult to do so. Therefore, we approximate optimal weights using finite subset, say F, of [0, 1]. We then develop a technique to measure the Degree of Approximation (DoA) of a weight set and obtain a weight set with the desired DoA. For a given F, approximate weights are calculated using a minimization problem that has a non-linear nature and thus may lead to multiple weights. To solve this issue, we first compute the collection of all approximate weights of the criterion, which is an interval, and then adopt the center of this interval as the approximate weight of the criterion. To measure the accuracy of a weight set, we develop the concepts of Consistency Index (CI) and Consistency Ratio (CR) for the proposed model. Finally, we discuss some numerical examples and a real-world application of the proposed model in ranking of risk factors in supply chain 4.0 and compare the results with existing models.

description: In the last 30 years, the mathematical theory of aperiodic order has developed enormously. Many new tilings and properties have been discovered, few of which are covered or anticipated by the early papers and books. Here, we start from the well-known Fibonacci chain to explain some of them, with pointers to various generalisations as well as to higher-dimensional phenomena and results. This should give some entry points to the modern literature on the subject.
