description: We review the definition of bulk and boundary conformal field theory in a way suited for logarithmic conformal field theory. The notion of a maximal bulk theory which can be non-degenerately joined to a boundary theory is defined. The purpose of this construction is to obtain the more complicated bulk theories from simpler boundary theories. We then describe the algebraic counterpart of the maximal bulk theory, namely the so-called full centre of an algebra in an abelian braided monoidal category. Finally, we illustrate the previous discussion in the example of the W(2,3)-model with central charge 0.

Specimens examined. 1 Ƥ, SURINAME, Boshhinis, 19-IV-1943, D.K. Geijskes leg. (MNRJ).
Remarks. So far two species of Tuberculobasis have been reported from Suriname: T. mammilaris by Belle (2002) and T. geijskesi described here. Median lobe of hind prothoracic lobe of T. sp. 3 (Fig. 56) is identical to that of the female of T. mammilaris (Fig. 50), and mesostigmal plate is also similar. However, an important difference is the presence of mesepisternal tubercles in T. sp. 3 and their absence in the female of T.
mammilaris. It is unlikely that T. sp. 3 represents the female of T. geijskesi in spite of the fact that these two species were collected in Suriname. Tuberculobasis geijskesi belongs in the mammilaris species group together with T. tirio, T. mammilaris, and T. yanomami. In all of them, females have no mesepisternal tubercles, and the same most probably occurs with the so far unknown female of T. geijskesi. Thus, T. sp. 3 is most likely a new species. Since, however, it might represent the female of one of the six species of Tuberculobasis known only from the male, I refrain from naming it here.

description: Ipamerica, gen. n.
Type-species: Ipamerica auctuncus sp. n.
Diagnosis. In facies, Ipamerica is similar to some species of Ricula Heinrich. However, the former differs by having a distinct incision of the termen beneath the apex of the forewing (lacking in Ricula) and in the reduction of the terminal row of spots (conspicuous in Ricula).
Description. Head: As in other Grapholitini. Thorax: Venation in forewing with R5 to termen beneath apex, M3-CuA1 widely separated basally, chorda from midway between R1-R2 to base of M1; M-stem atrophied. In hindwing all veins separate, except M3-CuA1 connate. Abdomen: Male genitalia with tegumen long with slender pedunculi; uncus slender, broadening basally; socii absent; gnathos and tuba analis weakly sclerotized; valva long, slender; sacculus moderately convex with ill-defined angle; ventral incision of valva indistinct, neck broad; cucullus long, slender, densely spined, rounded caudally; aedeagus broad, tapering ventroterminally; cornuti in examined specimen presumably deciduous, but about 20 sockets present. Female unknown.
Distribution and biology. Known from Goias, Brazil. Adults were collected in September and October at an elevation of 1000 m.
Etymology. The generic name is based on the name of the type locality of the type-species of the genus, Ipameri.

We focus on the polymer-induced entropic effects on mechanical properties of membranes. The spontaneous curvature and bending rigidity of the membranes increase with increasing polymer density. Our simulation results agree with the previous theoretical predictions.

subject: Respiratory diseases

description: O sistema respiratório desempenha um papel vital na troca gasosa, garantindo o suprimento de oxigênio ao organismo e a eliminação de dióxido de carbono, além de contribuir para o equilíbrio ácido-base no sangue. Patologias como asma, bronquite, doença pulmonar obstrutiva crônica (DPOC), pneumonia e tuberculose podem comprometer significativamente essa função e são responsáveis por um número expressivo de óbitos no Brasil. Esta pesquisa teve como objetivo analisar as taxas de mortalidade associadas a doenças respiratórias no país entre 1996 e 2022, com diferenciação por gênero, utilizando dados da plataforma integrada de vigilância em saúde (IVIS) do Ministério da Saúde. A metodologia consistiu na extração de dados de mortalidade por estado e ano, seguida pelo cálculo das taxas e projeções de óbitos futuros, utilizando o programa Blue Stats e técnicas de análise por regressão, um método de aprendizado de máquina semi-supervisionado. A visualização dos dados foi realizada com o JSFiddle, destacando as taxas de mortalidade por gênero na região Sudeste nos anos de 2000, 2010 e 2022, anos coincidentes com os censos do Instituto Brasileiro de Geografia e Estatística (IBGE). Os resultados indicam uma tendência de crescimento contínuo das taxas de mortalidade por doenças respiratórias em todos os estados, especialmente entre os homens. As análises temporais e regionais destacam variações significativas, evidenciando a necessidade urgente de políticas públicas que considerem as diferenças de gênero nas taxas de mortalidade. A conclusão aponta que as doenças respiratórias continuarão a ser um desafio crescente no Brasil, com uma tendência de aumento mais acentuada no sexo masculino. O conhecimento gerado por este estudo pode apoiar a formulação de políticas públicas voltadas para a prevenção e o tratamento dessas doenças, com especial atenção às populações mais vulneráveis. Para pesquisas futuras, propõe-se o refinamento das projeções de mortalidade e o desenvolvimento de intervenções específicas que possam reduzir as disparidades e melhorar a saúde pública no Brasil.

description: Affinities of Denticulobasis and Tuberculobasis
According to O'Grady & May (2003), the taxonomic characters commonly used for subfamily identification in Coenagrionidae are continuously distributed and subfamilies should not be recognized within Coenagrionidae until well-supported subdivisions are demonstrated. In view of this, I refrain from ascribing Denticulobasis and Tuberculobasis to any of the extant subfamilies. Denticulobasis and Tuberculobasis are close to Leptobasis and key out to this genus in Von Ellenrieder & Garrison (2008). Both genera share with Metaleptobasis the presence of mesepisternal processes that occur also in some species of Argia (Garrison, 1994). Table 2 shows the characters that separate these four genera.

DISTRIBUTION. — Indonesia, in sediments at 397-1264 m water depth.
OBSERVATIONS
Lectotype (ZMA V.Pol 1072.1) colorless, without posterior region, bent ventrally, breaking in two (Fig. 1A). Body about 10 mm long, 2.5 mm wide, 30 chaetigers. Prostomium (Fig. 1B) slightly eroded, left lateral antenna lost, right one present, inserted close to median antennal base. Median antenna thick, bent laterally, without tip. 2/3 as long as caruncle. Palps lost. Eyes not seen. Caruncle straight, with a median ridge and 4 digitate lateral lobes, directed posteriorly. Branchiae from chaetiger 1 lost; chaetiger 2 with 2 digitate filaments, in anterior chaetigers branchiae with about 5 filaments. Pharynx not exposed (Fig. 1C). Posterior end lost; pygidial features unknown.
REMARKS
Horst (1912: 33) did not see eyes in his specimens (longest one slightly more than 7 mm in length) but noted some black spots. Kudenov (1993: 96-97) noted in P. antarctica (Hartman, 1967) n. comb., specimens of different size (8-12 mm long) had eyes well developed and their pigments were retained despite being in ethanol for over 30 years, whereas in P. parva eyes were not seen. Horst (1912: 33) characterized the caruncle in the diagnosis for Pherecardites, and in the description of P. parva, as having a median ridge and lateral lamellae, directed posteriorly, extended along three segments. Branchiae were noted as starting in chaetiger 1 but the number of filaments was not given. Likewise, the presence of branchiae along posterior chaetigers was not indicated, nor the shape of the posterior end.

description: We study a family of non-C2-cofinite vertex operator algebras, called the singlet vertex operator algebras, and connect several important concepts in the theory of vertex operator algebras, quantum modular forms, and modular tensor categories. More precisely, starting from explicit formulae for characters of modules over the singlet vertex operator algebra, which can be expressed in terms of false theta functions and their derivatives, we first deform these characters by using a complex parameter ε. We then apply modular trans- formation properties of regularised partial theta functions to study asymptotic behaviour of regularised characters of irreducible modules and compute their regularised quantum dimensions. We also give a purely geometric description of the regularisation parameter as a uniformisation parameter of the fusion variety coming from atypical blocks. It turns out that the quantum dimensions behave very differently depending on the sign of the real part of ε. The map from the space of characters equipped with the Verlinde product to the space of regularised quantum dimensions turns out to be a genuine ring isomorphism for positive real part of ε while for sufficiently negative real part of ε its surjective image gives the fusion ring of a rational vertex operator algebra. The category of modules of this rational vertex operator algebra should be viewed as obtained through the process of a semi-simplification procedure widely used in the theory of quantum groups. Interestingly, the modular tensor category structure constants of this vertex operator algebra, can be also detected from vector valued quantum modular forms formed by distinguished atypical characters.

description: We give new proofs of the rationality of the N=1 superconformal minimal model vertex operator superalgebras and of the classification of their modules in both the Neveu-Schwarz and Ramond sectors. For this, we combine the standard free field realisation with the theory of Jack symmetric functions. A key role is played by Jack symmetric polynomials with a certain negative parameter that are labelled by admissible partitions. These polynomials are shown to describe free fermion correlators, suitably dressed by a symmetrising factor. The classification proofs concentrate on explicitly identifying Zhu's algebra and its twisted analogue. Interestingly, these identifications do not use an explicit expression for the non-trivial vacuum singular vector. While the latter is known to be expressible in terms of an Uglov symmetric polynomial or a linear combination of Jack superpolynomials, it turns out that standard Jack polynomials (and functions) suffice to prove the classification.

It is shown that the gravitational attraction of two material objects in accordance with Newton's law of gravity arises as a result of overlapping of the domains of the EM vacuum Casimir polarization created by atomic nuclei of the objects, taking into account the long-range gravitational influence of all masses of the Universe on each nucleus of these objects (Mach's idea). Newton's law of gravitational attraction between two bodies is generalized to the case of gravitational interaction of a system of bodies when the center of mass of the pair of bodies shifted relative to the center of mass of the system. The unique smallness of gravitational interactions as compared with the fundamental nuclear (strong and weak) and electromagnetic ones is determined by the ratio of the characteristic size of the domain of EM vacuum Casimir polarization in the vicinity of atomic nuclei to the Hubble radius of the Universe.

description: Lepidozonates Park, 2013
Type species: Lepidozonates viciniolus Park, 2013.
Lepidozonates Park, 2013: 223. Generic characters. Head: Antenna slightly shorter than forewing length. Labial palpus with second palpomere thickened, third palpomere slender.
Thorax: Forewing slightly widened distally; dark colored, with small pale-colored spot at costal margin (costal spot) and dorsum (dorsal spot) respectively (Fig. 3); usually with a discontinuous line running from costal to dorsal spots (subterminal line); cell closed; R 1 originating from middle of discal cell; R 2 free, R 3, R 4 +R 5 stalked, R 5 to apex or before apex; M 1 parallel to M 2; M 2 and M 3 +CuA 1+2 originating from same point, M 3, CuA 1 and CuA 2 stalked. Hindwing trapezoidal, wider than forewing; cell closed; Rs and M 1 stalked, M 2 absent, M 3 and CuA 1 stalked, CuA 2 remote from M 3 +CuA 1 at base (Fig. 5). Hind tibia with rough, elongate scales.
Abdomen: Abdominal segments IV–VI with specialized plumose scales on pleural membranes in the male (Fig. 7); abdominal tergites with zones of spiniform setae.
Male genitalia: Uncus elongate, broad basally, narrow distally. Gnathos with median process curved, wide at base, narrowed toward pointed apex. Tegumen with anterior margin concave in broad V-shape, with a heavily sclerotized broad band along inner margin. Valva widened distally (except in L. prominens). Juxta large, with or without posterior lobes. Aedeagus with cornuti of varied shape and size.
Female genitalia: Apophyses posteriores longer than apophyses anteriores. Ductus bursae twisted, with spines. Corpus bursae elliptical or ovate; signum elliptical or rounded, serrate along margins, with a large median groove.
Diagnosis. Lepidozonates is identical with Philharmonia Gozmány in the wing venation, but can be distinguished by the presence of the specialized plumose scales on the pleural membrane of the abdominal segments IV–VI in the male. This character is only found in Lepidozonates.

Description. Female. Body length 5.70± 0.51 mm; Head: Black; white mark at base of mandible, clypeus, spot at base of antenna, posterior to vertex, narrow stripe on paraocular area almost reaching middle of eye, broad stripe on gena; clypeus convex, without median longitudinal line, broader than long, anteriorly arched, apical margin with four denticles; mandible tridentate; anterior tentorial pit at intersection of subantennal and epistomal sulcus; F1 shorter than pedicel; first labial segment as long as second; interocular distance as long as interantennal distance.
Mesosoma: Legs black but variegated with white and ferruginous; broad white stripe on pronotal lobe, submedian longitudinal stripe on mesoscutum, apical margin of mesoscutellum interrupted medially, short lateral stripe on tegula, oblique apical stripe on mesoscutellum narrowly interrupted medially, outer surface of forefemora, tibiae and basitarsi of all legs; posterior margin of mesoscutellum rounded, overhanging metanotum; margins of pronotal lobe and mesoscutellum lamellate; wings hyaline; tarsal claws cleft; arolia present; hind tibia and basitarsus broadly dilated.
Metasoma: yellow square spot on T1 laterally, elongate spot laterally on T2, broadly interrupted transverse fascia across T3–T4, entire transverse fascia on T5, T6 with broad medial patch; scopa golden yellow; white fasciae of short plumose hairs beneath scopa absent.
Floral Associations: Tephrosia purpurea (Fabaceae) and Vitex negundo (Lamiaceae).
Flight period: March, April, and July.
Distribution. southern India.
Material examined. INDIA: Karnataka: Coorg, 2♀, 30.iii.1979; 1♀, 18.vii.1979, sweep net, collected by Girish; Mudigere, 2♀, 3.iv. 2008; 2♀, 12.iv. 2008, sweep net, collected by Girish; 1♀, 6.iv. 2009, sweep net, Nayana; Mudigere, 20 km SW, 1♀, 6.iv. 2008, Vitex negundo, Nayana.
Comments. Anthidiellum ramikrishnae belongs in a little known subgroup of subgenus Pycnanthidium that lacks a longitudinal carina on the hind tibia and hind basitarsus and has greatly expanded hind basitarsus (Griswold 2001). Other species in this group include A. butarsis Griswold, A. latipes (Bingham), and A. rasorium (Smith). From these A. ramakrishnae differs by the combination of integumental markings white, mesoscutum finely, contiguously punctate, and female hind basitarsus moderately broadened (length ~1.7x width).

Type material (ɗ). Holotype: NEW CALEDONIA: ɗ, New Caledonia, above Serraméa creek, leaf litter, 24.x.1998, I. Löbl / [red label], HOLOTYPE Anagonus breviscapus sp. nov., P. Hlaváč det., 2007 (MHNG).
Description. Body length about 1.85 mm, shining, with sparse long erect golden setae, head and pronotum light brown, elytra, abdomen, maxillary palpi, antennae and legs lighter, yellowish brown.
Head 1.3 times as long as wide, with wide frontal rostrum; rostral apex with deep, elongate impression between antennal tubercles which are well-defined; eyes with about 10 facets; maxillary palpi (Fig. 10) long, segment I minuscule, II with weakly defined inner tooth, III pedunculate at base, lacking lateral protuberance and lacking wrinkled surface; antennae very long, reaching middle of abdomen, scape about 4 times as long as pedicel and about 1.4 times as long as terminal antennomere, about half length of funicule, antennomeres II–VIII elongate, club three-segmented, antennomeres IX and X about as long as wide, terminal antennomere pointed at apex, about twice as long as wide and about 2.8 times as long as X.
Pronotum slightly longer than wide, and 1.3 times as long as head, widest before middle, lateral foveae small, lacking setae.
Legs long, protrochanter with two spines; basal spine longer and more robustr than apical one, almost as long as single basal spine on profemora.
Abdomen 1.5 times longer than elytra, first visible tergite (tergite IV) 1.8 times as long as second (V).
Remarks. Anagonus breviscapus can be easily separated from both congeners by the short scape and by the first visible tergite (tergite IV) 1.8 times as long as second (tergite V). Adeagus was lost during the preparation.
An additional specimen, a female collected from Col des Roussettes by Ivan Löbl (MHNG), is very similar to A. breviscapus, but has the first visible tergite (tergite IV) much shorter than in the holotype of A. breviscapus, not more that 1.5 times as long as the second visible tergite (tergite V). Further, this female specimen has a much larger body, about 2.2 mm long. For the time being I decided not to name this specimen.
Biology. The holotype was sifted from leaf litter in a humid ravine in tropical forest and extracted by Winkler-Mocsarski eclectors (Löbl, personal communication).
Etymology. The name of the new species refers to its short scape.

description: In this paper, we give a relationship between the covering number of a simple graph $G$, $β(G)$, and a new parameter associated to $G$ which is called 2-degree-packing number of $G$, $ν_2(G)$. We prove that$$\lceil ν_{2}(G)/2\rceil\leqβ(G)\leqν_2(G)-1,$$ for any connected simple graph $G$, with $|E(G)|>ν_2(G)$, and we give a characterization of simple connected graphs which attains the inequalities.
