description: The non-Hermitian skin effect (NHSE) is a distinctive topological phenomenon observed in nonHermitian systems. Recently, there has been considerable interest in exploring higher-order NHSE occurrences in two and three dimensions. In such systems, topological edge states collapse into a corner while bulk states remain delocalized. Through a Hermitian-non-Hermitian correspondence, this study predicts and experimentally observes the higher-order NHSE in an acoustic Kagome lattice possessing nonreciprocal hoppings. By rotating the frequency spectrum and employing complexfrequency excitation techniques, we observe the localization of acoustic energy towards a corner of the lattice in the topologically nontrivial phase, even when the source is located far from that corner. In contrast, the acoustic energy spreads out when excited at the frequencies hosting the bulk states. These observations are unequivocal evidence of the higher-order NHSE.

description: 10. OECODOMA ASPERSA. Pl. X. fig. 17. B.M.
Female. Length 3 1/2 lines. - Brown-black: the head and abdo- men roughened, covered with short sharp spines; the mandibles, scape, sides of the face, its anterior margin, the carinae between the antennae and the spines on the vertex, ferruginous. Thorax ovate, with two bright ferruginous longitudinal lines on the meso- thorax; the scutellum and post-scutellum ferruginous; a straight, stout, acute spine on each side of the thorax in front, and two longer bent acute ones on the metathorax, ferruginous; wings yellowish hyaline, the nervures pale ferruginous; the legs of moderate length, roughened with short spines and stiff hairs. Abdomen: the first node armed with a stout blunt spine on each side; the second node with numerous short spines on each side, the sides red; the first segment flattened towards the base, which has a ferruginous spot on each side; the apical margins of the seg- ments more or less ferruginous.
Hab. Brazil.
The close resemblance between this species and O. e hystrix leaves little doubt of the latter being the worker of the present species; the neuration of the wings of aspersa is somewhat different to the typical form of Oe. cephalotes, and it might be desirable to form a subgenus for its reception; for the present, we retain them as a section only.

description: We tune the onset of optical response in aluminium kinetic inductance detectors from a natural cutoff frequency of 90 GHz to 60 GHz by applying an external magnetic field. The change in spectral response is due to the decrease of the superconducting gap, from 90 GHz at zero magnetic field to 60 GHz at a magnetic field of around 3 mT. We characterize the variation of the superconducting gap, the detector frequency shift and the internal quality factor as a function of the applied field. In principle, the magnetic field tunable response could be used to make spectroscopic measurements. In practice, the internal quality factor behaves hysteretically with the magnetic field due to the presence of vortices in the thin superconducting film. We conclude by discussing possible solutions to achieve spectroscopy measurements using kinetic inductance detectors and magnetic field.

Species and subspecies: 3 species:
Species Myomimus personatus Ognev 1924
Species Myomimus roachi Bate 1937
Species Myomimus setzeri Rossolimo 1976
Discussion: This genus requires systematic revision. A new, undescribed species of Myomimus has been found in the C Zagros Mtns, Bakhtaran Prov., Iran, 1300 m. Known only from owl pellets, the mandible of this species is larger than that of M. setzeri, but smaller than M. personatus (Obuch, 2001; J. Obuch, pers. comm.); Obuch (2001) included photographs of dentaries of the new species compared with those of M. personatus and M. setzeri. Daams and de Bruijn (1995) arranged Myomimus in subfamily Myominae; according to their hypothesis myomimines and glirines originated from gliravines in the late Oligocene. There seems to be a general (but not universal, see Yachontov and Potapova, 1991, and Simson et al., 1995) consensus that Myomimus and Selevinia are related (Koenigswald, 1993, 1995; Potapova, 2001; Rossolimo et al., 2001; Storch, 1995 b; Wahlert et al., 1993). Phylogenetic analyses of nuclear DNA fragments and mitochondrial 12S rRNA sequences identified Myomimus as sister to a clade containing Dryomys and Eliomys within a larger evolutionary lineage corresponding to the Leithiinae of Wahlert et al. (1993). See comments under Subfamily Leithiinae for further taxonomic discussion. Evolutionary patterns of dental morphology during Pliocene and Pleistocene discussed by Nadachowski and Daoud (1995). Recorded from Pleistocene in E and SE Europe (Kowalski, 2001).

description: The volunteer's dilemma is a well-known game in game theory that models the conflict players face when deciding whether to volunteer for a collective benefit, knowing that volunteering incurs a personal cost. In this work, we introduce a quantum variant of the classical volunteer's dilemma, generalizing it by allowing players to utilize quantum strategies. Employing the Eisert-Wilkens-Lewenstein quantization framework, we analyze a multiplayer quantum volunteer's dilemma scenario with an arbitrary number of players, where the cost of volunteering is shared equally among the volunteers. We derive analytical expressions for the players' expected payoffs and demonstrate the quantum game's advantage over the classical game. In particular, we prove that the quantum volunteer's dilemma possesses symmetric Nash equilibria with larger expected payoffs compared to the unique symmetric Nash equilibrium of the classical game, wherein players use mixed strategies. Furthermore, we show that the quantum Nash equilibria we identify are Pareto optimal. Our findings reveal distinct dynamics in volunteer's dilemma scenarios when players adhere to quantum rules, underscoring a strategic advantage of decision-making in quantum settings.

description: We propose an electronic bipartite system consisting of a working substance, in which a refrigeration process is implemented, and of a nonthermal resource region, containing a combination of different thermal baths. In the working substance, heat is extracted from the coldest of two electronic reservoirs (refrigeration) via heat- and particle transport through a quantum dot. This quantum dot of the working substance is capacitively coupled to the resource region. In such a setup, a finite cooling power can be obtained in the working substance, while the energy exchange with the resource region exactly cancels out on average. At the same time, information is always exchanged, even on average, due to the capacitive coupling between the two parts of the bipartite system. The proposed system therefore implements an autonomous demon with fully vanishing heat extraction from the resource. Unlike macroscopic machines, nanoscale machines exhibit large fluctuations in performance, so precision becomes an important performance quantifier. We give a comprehensive description of the thermodynamic performance of the proposed autonomous demon in terms of stochastic trajectories and of full counting statistics and demonstrate that the precision of the cooling power strongly depends on the operation principle of the device. More specifically, the interplay of information flow and counter-balancing heat flows dramatically impacts the trade-off between cooling power, efficiency, and precision. We expect this insight to be of relevance for guiding the design of energy-conversion processes exploiting nonthermal resources.

description: We study the thermodynamics of Einstein gravity with vanishing cosmological constant subjected to conformal boundary conditions. Our focus is on comparing the series of subextensive terms to predictions from thermal effective field theory, with which we find agreement for the boundary theory on a spatial sphere, hyperbolic space, and flat space. We calculate the leading Wilson coefficients and observe that the first subextensive correction to the free energy is negative. This violates a conjectured bound on this coefficient in quantum field theory, which we interpret as a signal that gravity does not fully decouple in the putative boundary dual.

Worker major, length 2 lines. Worker minor, 1 1/2 line. - This species very closely resembles hystrix; its largest worker, however, is smaller than the smallest of that species, and its small worker the most diminutive of the genus. Mr. Bates says, " Very similar to the former (hystrix) in the number of the tho- racic spines, &c, but I think a distinct species. I found a pro- cession of them in a sandy tract of ground; all the individuals were of a uniform pale colour."

Species Selevinia betpakdalaensis Belosludov and Bazhanov 1939
Discussion: Belosludov and Bazhanov (1939) recognized Selevinia as a new genus of murids, and subsequently as the only member of a separate family of rodents seemingly allied to glirids (Bazhanov and Belosludov, 1941). Based upon a suite of morphological characters, Ognev (1947) hypothesized that Selevinia was a highly differentiated dormouse most closely related to Myomimus. Because of its distinct dental formula and structure, Ognev (1947) listed Selevinia in a separate subfamily, a hypothesis independantly suggested by Ellerman (1949 a). Published descriptions and figures of Selevinia included derived character states that allowed Wahlert et al. (1993) to tentatively place this genus within Myomimini, supporting Ognev's (1947) hypothesis. Though the nearest extant relative of Selevinia is proposed to be Myomimus, its closest relative may be Plioselevinia, from early Pliocene breccia of Poland (McKenna and Bell, 1997).

description: An axion-like spectator during inflation can trigger a tachyonic instability which amplifies the modes of one of the helicities of the gauge field, resulting in the production of parity-violating gravitational waves (GWs). In this paper we investigate the impact of the coupling $RFF$ of the gauge field to gravity on the production of GWs. We find that such a coupling introduces a multiplicative factor to the tachyonic mass, which effectively enhances the amplitude of the gauge field modes. Produced GWs are expected to be observed by future space-based GW detectors. Additionally, we find that the strong backreaction due to particle production leads to multiple peaks in the energy spectrum of GWs.

Species Glirulus japonicus (Schinz 1845)
Discussion: The phylogenetic study by Wahlert et al. (1993) supports inclusion of Glirulus within Glirinae, as did Montgelard et al.’s (2003) phylogenetic analyses of nuclear and mitochondrial gene sequences (see also comment under Glirinae). Daams and de Bruijn (1995) arranged this genus within their Dryomyinae (in which they also include Dryomys, Eliomys, Graphiurus and Chaetocauda). Suzuki et al. (1997) presented genetic data indicating that Glirulus may belong in its own subfamily, though their study only included Dryomys and Muscardinus for comparison. Although the geographic range of the sole extant species of Glirulus is restricted to Japan, the genus is represented in Europe and Turkey by early Miocene, Pliocene and early Pleistocene fossils (Bednarczyk, 1993; Daams and de Bruijn, 1995; Hugueney and Mein, 1965; Kowalski, 1963, 2001; Nadachowski and Daoud, 1995; Unay, 1994). Molars identified as Glirulus from late Oligocene beds in Xinjiang Prov. of NW China provide the oldest record of not only a dormouse from China but of Glirulus itself (Wu et al., 2000). A late Miocene fossil from Ardèche, France, suggests that an extinct species of Glirulus was capable of gliding (Mein and Romaggi, 1991). Evolutionary patterns of dental morphology during Pliocene and Pleistocene discussed by Nadachowski and Daoud (1995).

description: Spontaneous symmetry breaking can persist at all temperatures in certain biconical $\mathrm{O}(N)\times \mathbb{Z}_2$ vector models when the underlying field theories are ultraviolet complete. So far, the existence of such theories has been established in fractional dimensions for local but nonunitary models or in 2+1 dimensions but for nonlocal models. Here, we study local models at zero and finite temperature directly in 2+1 dimensions employing functional methods. At zero temperature, we establish that our approach describes the quantum critical behaviour with high accuracy for all $N\geq 2$. We then exhibit the mechanism of discrete symmetry breaking from $\mathrm{O}(N)\times \mathbb{Z}_2\to \mathrm{O}(N)$ for increasing temperature near the biconical critical point when $N$ is finite but large. We calculate the corresponding finite-temperature phase diagram and further show that the Hohenberg-Mermin-Wagner theorem is fully respected within this approach, i.e., symmetry breaking only occurs in the $\mathbb{Z}_2$ sector. Finally, we determine the critical $N$ above which this phenomenon can be observed to be $N_c \approx 15$.
