Signatures of Cooper pair dynamics and quantum-critical superconductivity in tunable carrier bands

Different superconducting pairing mechanisms are markedly distinct in the underlying Cooper pair kinematics. Quantum-critical soft modes drive pairing interactions in which the pair scattering processes are highly collinear and can be classified into two categories: forward scattering and backscattering. Conversely, in conventional phonon mechanisms, Cooper pair scattering is of a generic noncollinear character. In this study, we present a method to discern the kinematic type by observing the evolution of superconductivity while adjusting the Fermi surface geometry. To demonstrate our approach, we utilize the recently reported phase diagrams of untwisted graphene multilayers. Our analysis connects the emergence of superconductivity at "ghost crossings" of Fermi surfaces in distinct valleys to the pair kinematics of a backscattering type. Together with the observed nonmonotonic behavior of superconductivity near its onset (sharp rise followed by a drop), it lends strong support to a particular quantum-critical superconductivity scenario in which pairing is driven by intervalley coherence fluctuations. These findings offer direct insights into the genesis of pairing in these systems, providing compelling evidence for the electron-electron interactions driving superconductivity. More broadly, our work highlights the potential of tuning bands via ghost crossings as a promising means of boosting superconductivity.

Coyote figurations, Techne and Feminism

It is within the framework of situated knowledges in the field of biology and technology studies, in its relation to feminism that the coyote figuration is conceptualized by Donna Haraway. In what respect are they conceived by Donna Haraway to be figures of emancipation? What kind of affinity does it establishes with the figure of cyborg, as figure of posthumanism? Certainly, Donna Haraway hypothesizes the privilege of a ‘partial perspective’ having to play a role in expanding the epistemic horizon of feminist thought. This paper probes into the potential role of coyote figures as metaphors illuminating feminist readings of the relation between philosophy and technology. However, coyote figures have a generic character of transgression, and hence, borders on epistemological reduction of its ontico-ontological phenomenality which Catherine Malabou problematizes. Malabou’s eschewal of flexibility counters this binary by developing the role played by the “fantastic” in the espousal of plasticity of being. Being conceived in this originary mutability eliminates the interior-exterior division of beings. What are the comparable features of coyote figurations and the fantastic? And how does it add to the feminist understanding of philosophy of technology?

Writing Into Water.

Writing is an ancient communication technique dating back at least 30 000 years. While even sophisticated contemporary writing techniques hinge on solid surfaces for engraving or the deposition of ink, writing within a liquid medium requires a fundamentally different approach. The study here demonstrates the writing of lines, letters, and complex patterns in water by assembling lines of colloidal particles. Unlike established techniques for underwater writing on solid substrates, these lines are fully reconfigurable and do not require any fixation onto the substrate. Exploiting gravity, an ion-exchange bead (pen) is rolled across a layer of sedimented colloidal particles (ink). The pen evokes a hydrodynamic flow collecting ink-particles into a durable, high-contrast line along its trajectory. Deliberate substrate-tilting sequences facilitate pen-steering and thus drawing and writing. The experiments are complemented with a minimal model that quantitatively predicts the observed parameter dependence for writing in fluids and highlights the generic character of writing by line-assembly. Overall, the approach opens a versatile route for writing, drawing, and patterning fluids-even at the micro-scale.

On the taxonomy of Philyra sagittifera (Alcock, 1896) and P. concinnus Ghani & Tirmizi, 1995 (Decapoda, Brachyura, Leucosiidae), with description of a new genus from the Indian Ocean.

The identity of the leucosiid crabs, Philyra sagittifera (Alcock, 1896) and P. concinnus Ghani & Tirmizi, 1995, originally described from Pakistan is clarified. Redescription of the lectotype male of Philyra sagittifera (Alcock, 1896) and fresh material of both species collected from the Persian Gulf revealed that these two species show significant morphological differences from the generic characters of Philyra sensu stricto and other allied genera in possessing three broad tuberculated ridges united to form a "broad-arrow" pointing forwards on the carapace, and male G1 with apical process curved, with or without a spatulate tip. Therefore, a new genus Tirmilyra n. gen. is established to accommodate both species.

Interpolations of monoidal categories and algebraic structures by invariant theory

In this paper we give a general construction of symmetric monoidal categories that generalizes Deligne’s interpolated categories, the categories introduced by Knop, and the recent TQFT construction of Khovanov, Ostrik, and Kononov. The categories we will consider are generated by an algebraic structure. In a previous work by the author a universal ring of invariants mathfrak {U} for algebraic structures of a specific type was constructed. It was shown that any algebraic structure of this type in {text {Vec}}_K gives rise to a character chi :mathfrak {U}rightarrow K. In this paper we consider algebraic structure in general symmetric monoidal categories, not only in {text {Vec}}_K, and general characters on mathfrak {U}. From any character chi :mathfrak {U}rightarrow K we construct a symmetric monoidal category {mathcal {C}}_{chi }, analogous to the universal construction from TQFT. We then give necessary and sufficient conditions for a given character to arise from a structure in an abelian category with finite dimensional hom-spaces. We call such characters good characters. We show that if chi is good then {mathcal {C}}_{chi } is abelian and semisimple, and that the set of good characters forms a K-algebra. We also show that the categories {mathcal {C}}_{chi } contain all categories of the form {text {Rep}}(G), where G is reductive. The construction of {mathcal {C}}_{chi } gives a way to interpolate algebraic structures, and also symmetric monoidal categories, in a way that generalizes Deligne’s categories {text {Rep}}(S_t), {text {Rep}}({text {GL}}_t(K)), and {text {Rep}}(text {O}_t). We also explain how one can recover the recent construction of 2 dimensional TQFT of Khovanov, Ostrik, and Kononov, by the methods presented here. We give new examples, of interpolations of the categories {text {Rep}}({text {Aut}}_{{mathcal {O}}}(M)) where {mathcal {O}} is a discrete valuation ring with a finite residue field, and M is a finite module over it. We also generalize the construction of wreath products with S_t, which was introduced by Knop.

The Oriental spittlebug genus Paracercopis Schmidt (Hemiptera: Cercopoidea: Cercopidae) revisited, with description of one new species from Hubei, China.

The generic diagnostic characters of Paracercopis (Hemiptera: Cercopoidea: Cercopidae) are redefined and the autapomorphies are proposed to support the monophyly of the genus. Scanning electron micrographs of antennal sensilla and sensilla on rostral apex of P. seminigra (Melichar, 1902) are provided for the first time. A checklist together with new distribution records and key to the species of the genus are provided. Host plant associations of Paracercopis species are reported for the first time. Paracercopis unicolor Liang, Zhang & Xiao, sp. nov., representing the seventh and largest species of the genus is described from Hubei Province in south central China.

Engineering Lewis Acidity in Zeolite Catalysts by Electrochemical Release of Heteroatoms during Synthesis.

The creation of heteroatom nodes in zeolite frameworks is a challenging but rewarding pathway to superior materials for numerous catalytic applications. Here, we present a novel method for precise control over heteroatom incorporation by in situ anodic release of a desired metal during hydrothermal zeolite synthesis. The generic character of the technique and the applicability of the new synthesis reactor are shown across 3 zeolite structures crystallized and 4 electrode metals in two pH zones and by offering access to a new mixed-metal zeolite. The timed and voltage-controlled metal release offers a minimized interference between the metal precursor state and critical events in the zeolite's crystallization. A mechanistic study for Sn-MFI revealed the key importance of controlled release: while keeping its concentration lower than in batch, a lot more Sn can be incorporated into the framework. The method grants access to 10× increased framework Lewis acid site densities (vs batch controls) for the most relevant stannosilicates. As a proof, the electro-made materials demonstrate higher productivity than their classic counterparts in lactate catalysis. This innovative approach effectively expands the synthesis space of zeolites.

Interpolated family of non-group-like simple integral fusion rings of Lie type

This paper is motivated by the quest of a non-group irreducible finite index depth 2 maximal subfactor. We compute the generic fusion rules of the Grothendieck ring of Rep(PSL(2,[Formula: see text])), [Formula: see text] prime-power, by applying a Verlinde-like formula on the generic character table. We then prove that this family of fusion rings [Formula: see text] interpolates to all integers [Formula: see text], providing (when [Formula: see text] is not prime-power) the first example of infinite family of non-group-like simple integral fusion rings. Furthermore, they pass all the known criteria of (unitary) categorification. This provides infinitely many serious candidates for solving the famous open problem of whether there exists an integral fusion category which is not weakly group-theoretical. We prove that a complex categorification (if any) of an interpolated fusion ring [Formula: see text] (with [Formula: see text] non-prime-power) cannot be braided, and so its Drinfeld center must be simple. In general, this paper proves that a non-pointed simple fusion category is non-braided if and only if its Drinfeld center is simple; and also that every simple integral fusion category is weakly group-theoretical if and only if every simple integral modular fusion category is pointed.

Newton Polygons of Sums on Curves II: Variation in p-adic Families

Abstract In this article, we study the behavior of Newton polygons along $\mathbb{Z}_p$-towers of curves. Fix an ordinary curve $X$ over a finite field $\mathbb{F}_q$ of characteristic $p$. By a $\mathbb{Z}_p$-tower $X_\infty /X$, we mean a tower of covers $ \dots \to X_2 \to X_1 \to X$ with $\textrm{Gal}(X_n/X) \cong \mathbb{Z}/p^n\mathbb{Z}$. We show that if the ramification along the tower is sufficiently moderate, then the slopes of the Newton polygon of $X_n$ are equidistributed in the interval $[0,1]$ as $n$ tends to $\infty $. Under a stronger congruence assumption on the ramification invariants, we completely determine the slopes of the Newton polygon of each curve. This is the first result towards “regularity” in Newton polygon behavior for $\mathbb{Z}_p$-towers over higher genus curves. We also obtain similar results for $\mathbb{Z}_p$-towers twisted by a generic tame character.

Revision of the plant bug genus Diognetus, with descriptions of thirteen new species from the Oriental and Eastern Palearctic Regions (Hemiptera: Heteroptera: Miridae)

The mirine plant bug genus Diognetus Distant, 1904 (Hemiptera: Heteroptera: Miridae: Mirinae: Mirini) is revised. Eighteen Oriental and Eastern Palearctic species are properly assigned to the genus. Diplotrichiella Poppius, 1915, syn. nov. and Yamatolygus Yasunaga, 1994, syn. nov. are synonymized with Diognetus; accordingly the following two new combinations, one substitute name and one new synonymy are proposed: Diognetus flavigenis (Horváth, 1905) comb. nov. and D. insulanus (Yasunaga, 1994) comb. nov. (transferred from Yamatolygus); D. yamato Yasunaga nom. nov. for Yamatolygus pilosus Yasunaga, 1994, junior secondary homonym of D. pilosus (Poppius, 1914); and Diplotrichiella rufescens Poppius, 1914, syn. nov. = Diognetus intonsus Distant, 1904 (valid name). Thirteen species are described as new: Diognetus bagmaticus sp. nov. (from Nepal), D. cheimon sp. nov. (Japan), D. dhampus sp. nov. (Nepal), D. duwalorum sp. nov. (Nepal), D. giganteus sp. nov. (Malaysia), D. gotohi sp. nov. (Malaysia), D. laureus sp. nov. (Japan), D. magnificus sp. nov. (Indonesia), D. minusculus sp. nov. (Malaysia), D. puspae sp. nov. (Nepal), D. schuhorum sp. nov. (Indonesia), D. styrax sp. nov. (Taiwan) and D. vernus sp. nov. (Japan). The generic characters are reassessed and discussed, on the basis of detailed observation of external structures using scanning electron microscopy as well as male and female genitalia.

They’re valuable enough that a violent, armed group called MAGs (Men and Guns) steals Giften away to be experimented on, sparking the existence of the Sanctuary, a Giften-only community, and a rebel group called the Circle. When Ruthie shows signs of being Giften and her father returns to their town after going missing several years ago, he offers to take her away before the MAGs can get her, but their journey won’t be easy as they get caught in the middle of the warring groups. Simplified worldbuilding, generic characters, and a villain with no interesting motive will turn off fans of dystopian fiction who have tired of books that rehash the same tropes of their predecessors. Still, the pacing is breakneck and makes for an action-packed read, and Ruthie being fifteen will appeal to younger teens. Collections with outdated dystopian fiction hoping to introduce newer work may still consider this book. Copyright © 2023 The Board of Trustees of the University of Illinois

Dust acoustic wave properties in varying discharge volumes

Properties of self-excited dust acoustic waves under the influence of active compression of the dust particle system were experimentally studied in the laboratory and under microgravity conditions (parabolic flight). Ground based laboratory experiments clearly show that wave properties can be manipulated by changing the discharge volume, its aspect ratio, and thus the dust particle density. Complementary experiments under microgravity conditions, performed to exclude the effects of gravity inflicted sedimentation and anisotropic behavior, were less conclusive due to residual fluctuations in the planes acceleration indicating the need for a better microgravity environment. A theoretical model, using plasma parameters obtained from particle-in-cell simulations as input, supports the experimental findings. It shows that the waves can be described as a new observation of the dust acoustic mode, which demonstrates their generic character.

Synopsis of the Neotropical Premnobiina (Coleoptera: Curculonidae: Scolytinae: Ipini) with descriptions of new species, new synonymy and keys to species

One new species of Neotropical Premnobius Eichhoff is described: P. brownei Atkinson & Flechtmann from Brazil. The presence of the related genus Premnophilus Browne is confirmed from South America and six new species are described: P. bertii Atkinson & Flechtmann from Brazil, P. jordali Petrov from Peru, P. maiai Atkinson & Flechtmann from Brazil, P. pedrosai Atkinson & Flechtmann from Brazil, P. sarahsmithae Atkinson & Flechtmann from Brazil and Trinidad and Tobago, and P. wilsoni Atkinson & Flechtmann from Brazil. French Guiana, and Peru. Gnathotrupes megapunctatus Bright, 2019 is recognized as a synonym of Premnobius perezdelacruceii Petrov & Atkinson, 2018. A synopsis of previously described Premnobius species and keys to species in both genera are presented. Generic characters for the three genera of Neotropical Ipini are discussed.

Age-Related Melanism in Macroparalepis brevis (Paralepididae)

Age-related melanism for a dwarf species of the genus Macroparalepis, M. brevis, was described for the first time; thus, this phenomenon turns out to be a common generic character. Presumably, the trigger for coloration change is the transition to a mesobenthic lifestyle. The phylogenetic significance of age-related melanism in barracudinas (Paralepididae) is discussed, which may support a kinship of the genera Macroparalepis and Stemonosudis (including Dolichosudis). The species D. fuliginosa was recorded in the Indian Ocean for the first time.

A new Darwin wasp genus, Soliga (Hymenoptera: Ichneumonidae: Metopiinae), from India

Metopiinae is a relatively large subfamily of Darwin wasps with a cosmopolitan distribution. Species of this subfamily can be distinguished by a convex, and mostly undivided face and clypeus. Among 113 species in 24 genera of the Oriental region, only 24 species in eight genera are reported from India. Here, we describe and illustrate a new genus, Soliga, based on collections made from the Western Ghats and Eastern Himalayas, two important biodiversity hotspots. The combination of absence of epicnemial carina on dorsolateral part of mesopleuron, absence of propodeal carinae and dorsal carinae of first metasomal tergite differentiates the new genus from other metopiine genera. An illustrated key to the Indo-Australian metopiine genera is provided along with comments on new generic placement and character variability of metopiines.

Baldinia droopii sp. nov. (Suessiales, Dinophyceae), a new species from a small rainwater rock pool near Tvärminne, south-western Finland

ABSTRACT A dinoflagellate isolated from a small rainwater rockpool in Finland was found to be a new species of Baldinia, here described as B. droopii sp. nov. This is only the third formally described Baldinia species and the second described by modern methods. The new species had a complement of generic characters that clearly affiliated it to Baldinia: presence of an internal honeycomb structure, termed a lamellar body, a ventral fibre associated with the longitudinal basal body and a pentagonal resting cyst; and the absence of an apical structure, thecal plates and trichocysts. The most distinctive species-specific characters were the presence of a resting cyst with tubiform processes, a paratabulation matching the pattern of the motile cell, and a life cycle exhibiting a diel rhythm, alternating between motile and non-motile coccoid cells. Motile cells occurred during the light period, peaking after 3–4 h of light period, while practically no motile cells occurred during the dark period. LSU rDNA sequences confirmed B. droopii as a new species, showing c. 14% sequence difference compared to B. anauniensis. Asexual reproduction occurred primarily by binary fission or via a so-called division cyst. Sexual reproduction occurred in the culture indicating that D. droopii is homothallic. The zygote may form a resistant cyst with tubiform processes, but there were indications that this stage may be by-passed. Different stages of the asexual and putative sexual reproduction were observed and documented by video recordings.

THE TYPOLOGY OF QUANTITATIVE QUALIFIERS MARKING “MULTIPLE, EXCESSIVE, EXTREME” IN OLD TURKIC

Adjectives and adverbs, which are responsible for qualifying nouns, nouns and verbs according to the common and classical grammatical approach, are units that characterize these word categories from a wide variety of aspects. The fact that the same lexical units qualify both nouns and denominal words and verbs is related to their syntactic duties. In this respect, the units in the category with available functions are called “qualifiers”. Considering that the most convenient approach for the typology of world languages is to evaluate historical periods diachronically, the importance of archaic forms for qualifiers will come to the fore even more. Therefore, in order to study the qualifiers of Turkic, thefirst written inventory of the language in question and the various circles included in the scope of this period (VIII-XI century) will be the field from which the most appropriate data document will be obtained. Because the texts written in this period, especially in the Buddhist and Islamic environment, are very rich in terms of qualifiers. In this article, typologies of qualifiers identified in the first written inventory of Turkic between the eighth and eleventh centuries are examined. Since the existence of quite a variety of qualifiers makes it difficult to study these units in Turkic, the study will focus on the quantity qualifiers declaring “multiple, excessive, extreme”and from this point of view, it will be tried to reach the general qualifier characters. The general anatomy of the qualifiers will be revealed with a classification over the grammaticalization stages, conceptual relations and syntactic sequences of the quantity qualifiers to be discussed. In this way, both diachronic and synchronicfindings will be reached and findings that will contribute to language universality and language typology will be revealed.

A new species of dendrochirotid holothuroid from deep water of southern Japan, with the erection of a new genus, Satsumaocnus (Echinodermata: Holothuroidea: Dendrochirotida: Cucumariidae: Colochirinae)

A new dendrochirotid sea cucumber, Satsumaocnus kaiyomarui gen. nov., sp. nov. from deep water of southern Japan is herein described. The new species displays the following unique characters : a cylindrical, soft body; mouth surrounded by five oral valves; 10 equal, dendritic tentacles arranged in a single circle, each composed of two tufts; a low, stout, compact, calcareous ring without posterior prolongations; body wall ossicles comprising an external layer of small, x-framed hourglass-shaped cups originally described as "double-faced x-framed cup ossicles" in a previous study reported by Yamana et al. (2019), and an inner layer of scarce dendriform/branched rods, sometimes taking the shape of delicate plate-like deposits. Although the general (external and internal) morphological characters of the new species correspond well with the characters of species within the cucumariid subfamily Colochirinae Panning, 1949, our material lacks any buttons or elaborate plate-like ossicles which characterize all extant genera within this subfamily. We, therefore, describe our material as a new species S. kaiyomarui sp. nov. within the new genus Satsumaocnus. The predominant body wall deposits of the new species strongly resemble the hourglass type ossicles of some species of the psolid genus Lissothuria (Verrill, 1867), but differ in their possession of a supporting x-shaped frame. In addition, it is noteworthy that these hourglass deposits also resemble the table ossicles of some holothuriids and stichopodids, when viewed from the side, especially the small tables of some Labidodemas and/or Stichopus species, while the dendriform rods resemble those of Thelenota.
