Homogeneously weighted moving average ( H W M A ) charts have recently achieved popularity for monitoring small changes in process parameters (location and/or dispersion). Furthermore, the D H W M A (double H W M A ) and T H W M A (triple H W M A ) are the advanced versions of the H W M A charts. The H W M A chart for the process dispersion is designed to detect only the upward (one-sided) shift (i.e., process deterioration). Employing a two-sided chart for concurrently detecting both process improvement and process deterioration is an important aspect of statistical process monitoring. By taking this point as motivation, one and two-sided T H W M A charts (symbolized as the T H W M A V ) are proposed for monitoring the process dispersion. The Monte Carlo simulations are performed to investigate the performance behavior of the T H W M A V charts in terms of certain performance indicators, including A R L , S D R L , E Q L , R A R L , and P C I . The comparison among the T H W M A V versus existing charts ( D H W M A V , H W M A V , T E W M A V , D E W M A V , and E W M A V ) indicates that the T H W M A V charts outperform the existing charts. Finally, a dataset is also analyzed to illustrate the implementation of the T H W M A V charts.

Abstract Let G be an abelian group with identity e e . Let R be a G-graded commutative ring with identity 1, and M M be a graded R-module. In this paper, we introduce the concept of graded J g r {J}_{gr} -classical 2-absorbing submodule as a generalization of a graded classical 2-absorbing submodule. We give some results concerning of these classes of graded submodules. A proper graded submodule C C of M M is called a graded J g r {J}_{gr} -classical 2-absorbing submodule of M M , if whenever r g , s h , t i ∈ h ( R ) {r}_{g},{s}_{h},{t}_{i}\in h\left(R) and x j ∈ h ( M ) {x}_{j}\in h\left(M) with r g s h t i x j ∈ C {r}_{g}{s}_{h}{t}_{i}{x}_{j}\in C , then either r g s h x j ∈ C + J g r ( M ) {r}_{g}{s}_{h}{x}_{j}\in C+{J}_{gr}\left(M) or r g t i x j ∈ C + J g r ( M ) {r}_{g}{t}_{i}{x}_{j}\in C+{J}_{gr}\left(M) or s h t i x j ∈ C + J g r ( M ) , {s}_{h}{t}_{i}{x}_{j}\in C+{J}_{gr}\left(M), where J g r ( M ) {J}_{gr}\left(M) is the graded Jacobson radical.

In this paper we introduce a new class of operators called M−quasi paranormal operators. A bounded linear operator T in a complex Hilbert space H is said to be a M−quasi paranormal operator if it satisfies ∥T 2x∥ 2 ≤ M∥T 3x∥ · ∥T x∥, ∀x ∈ H, where M is a real positive number. We prove basic properties, the structural and spectral properties of this class of operators.

Multifractional processes are stochastic processes with non-stationary increments whose local regularity and self-similarity properties change from point to point. The paradigmatic example of them is the classical Multifractional Brownian Motion (MBM) { M ( t ) } t ∈ R \{{\mathcal {M}}(t)\}_{t\in \mathbb {R}} of Benassi, Jaffard, Lévy Véhel, Peltier and Roux, which was constructed in the mid 90’s just by replacing the constant Hurst parameter H {\mathcal {H}} of the well-known Fractional Brownian Motion by a deterministic function H ( t ) {\mathcal {H}}(t) having some smoothness. More than 10 years later, using a different construction method, which basically relied on nonhomogeneous fractional integration and differentiation operators, Surgailis introduced two non-classical Gaussian multifactional processes denoted by { X ( t ) } t ∈ R \{X(t)\}_{t\in \mathbb {R}} and { Y ( t ) } t ∈ R \{Y(t)\}_{t\in \mathbb {R}} . In our article, under a rather weak condition on the functional parameter H ( ⋅ ) {\mathcal {H}}(\cdot ) , we show that { M ( t ) } t ∈ R \{{\mathcal {M}}(t)\}_{t\in \mathbb {R}} and { X ( t ) } t ∈ R \{X(t)\}_{t\in \mathbb {R}} as well as { M ( t ) } t ∈ R \{{\mathcal {M}}(t)\}_{t\in \mathbb {R}} and { Y ( t ) } t ∈ R \{Y(t)\}_{t\in \mathbb {R}} only differ by a part which is locally more regular than { M ( t ) } t ∈ R \{{\mathcal {M}}(t)\}_{t\in \mathbb {R}} itself. On one hand this result implies that the two non-classical multifractional processes { X ( t ) } t ∈ R \{X(t)\}_{t\in \mathbb {R}} and { Y ( t ) } t ∈ R \{Y(t)\}_{t\in \mathbb {R}} have exactly the same local path behavior as that of the classical MBM { M ( t ) } t ∈ R \{{\mathcal {M}}(t)\}_{t\in \mathbb {R}} . On the other hand it allows to obtain from discrete realizations of { X ( t ) } t ∈ R \{X(t)\}_{t\in \mathbb {R}} and { Y ( t ) } t ∈ R \{Y(t)\}_{t\in \mathbb {R}} strongly consistent statistical estimators for values of their functional parameter.

O segmento de papel e celulose tem posição de destaque na economia do setor florestal brasileiro e mundial. O objetivo deste estudo foi analisar a dinâmica da produção, importação, exportação e consumo aparente de três tipos de papéis (P+W: imprimir e escrever, H+S: uso doméstico e sanitário e N: jornal) no período de 1961 a 2016. Para essa análise foram utilizados dados extraídos do sistema FAOSTAT da FAO. Os resultados encontrados demonstram que nesse período foram produzidas 77 M t de P+W, 24 M t de H+S e 9 M t de N. As importações totalizaram 10 M t, 188 mil t e 12 M t, respectivamente para P+W, H+S e N. As exportações no período foram de 25 M t, 500 mil t e 334 mil t, respectivamente. O consumo aparente foi de 61 M t, 24 M t e 21 M t, respectivamente. O consumo médio per capita desses papéis no período foi de 6,98; 2,58 e 2,57 kg.hab-1. O consumo de H+S deu-se de forma crescente em toda a série temporal, enquanto que para P+W e N foi decrescente, sobretudo a partir de 2010. O Brasil é superavitário em P+W e H+S e deficitário na balança comercial em N. Conclui-se que há uma tendência de queda de consumo em P+W e N e aumento de H+S, essa tendência é verificada na produção, importação e consumo. As exportações de H+S e N ainda são pouco expressivas. Já as importações de P+W e N apresentaram tendência de queda desde 2010.

UDC 512.5 Let R be a commutative Noetherian ring, let Φ be a system of ideals of R , let M be a finitely generated R -module, and let t be a nonnegative integer. We first show that a general local cohomology module H Φ i ( M ) is a finitely generated R -module for all i < t if and only if A s s R ( H Φ i ( M ) ) is a finite set and H Φ 𝔭 i ( M 𝔭 ) is a finitely generated R 𝔭 -module for all i < t and all 𝔭 ∈ S p e c ( R ) . Then, as a consequence, we prove that if ( R , 𝔪 ) is a complete local ring, Φ is countable, and n ∈ ℕ 0 is such that ( A s s R ( H Φ h Φ n ( M ) ( M ) ) ) ≥ n is a finite set, then f Φ n ( M ) = h Φ n ( M ) . In addition, we show that the properties of vanishing and finiteness of general local cohomology modules are equivalent on high points over an arbitrary Noetherian (not necessary local) ring. For each covariant R -linear functor T from M o d ( R ) into itself, which has the global vanishing property on M o d ( R ) and for an arbitrary Serre subcategory 𝒮 and t ∈ ℕ , we prove that ℛ i T ( R ) ∈ 𝒮 for all i ≥ t if and only if ℛ i T ( M ) ∈ 𝒮 for any finitely generated R -module M and all i ≥ t . Then we obtain some results on general local cohomology modules.

Three new genera are described: Michener (Proteropinae), Bioalfa (Rogadinae), and Hermosomastax (Rogadinae). Keys are given for the New World genera of the following braconid subfamilies: Agathidinae, Braconinae, Cheloninae, Homolobinae, Hormiinae, Ichneutinae, Macrocentrinae, Orgilinae, Proteropinae, Rhysipolinae, and Rogadinae. In these subfamilies 416 species are described or redescribed. Most of the species have been reared and all but 13 are new to science. A consensus sequence of the COI barcodes possessed by each species is employed to diagnose the species, and this approach is justified in the introduction. Most descriptions consist of a lateral or dorsal image of the holotype, a diagnostic COI consensus barcode, the Barcode Index Number (BIN) code with a link to the Barcode of Life Database (BOLD), and the holotype specimen information required by the International Code of Zoological Nomenclature. The following species are treated and those lacking authorship are newly described here with authorship attributable to Sharkey except for the new species of Macrocentrinae which are by Sharkey & van Achterberg: AGATHIDINAE: Aerophilus paulmarshi, Mesocoelus davidsmithi, Neothlipsis bobkulai, Plesiocoelus vanachterbergi, Pneumagathis erythrogastra (Cameron, 1905), Therophilus bobwhartoni, T. donaldquickei, T. gracewoodae, T. maetoi, T. montywoodi, T. penteadodiasae, Zacremnops brianbrowni, Z. coatlicue Sharkey, 1990, Zacremnops cressoni (Cameron, 1887), Z. ekchuah Sharkey, 1990, Z. josefernandezi, Zelomorpha sarahmeierottoae.

AbstractGiven Hilbert space operators T,S\in B( {\mathcal H} ), let \text{Δ} and \delta \in B(B( {\mathcal H} )) denote the elementary operators {\text{Δ}}_{T,S}(X)=({L}_{T}{R}_{S}-I)(X)=TXS-X and {\delta }_{T,S}(X)=({L}_{T}-{R}_{S})(X)=TX-XS. Let d=\text{Δ} or \delta . Assuming T commutes with {S}^{\ast }, and choosing X to be the positive operator {S}^{\ast n}{S}^{n} for some positive integer n, this paper exploits properties of elementary operators to study the structure of n-quasi {[}m,d]-operators {d}_{T,S}^{m}(X)=0 to bring together, and improve upon, extant results for a number of classes of operators, such as n-quasi left m-invertible operators, n-quasi m-isometric operators, n-quasi m-self-adjoint operators and n-quasi (m,C) symmetric operators (for some conjugation C of {\mathcal H} ). It is proved that {S}^{n} is the perturbation by a nilpotent of the direct sum of an operator {S}_{1}^{n}={\left(S{|}_{\overline{{S}^{n}( {\mathcal H} )}}\right)}^{n} satisfying {d}_{{T}_{1},{S}_{1}}^{m}({I}_{1})=0, {{T}_{1}=T}_{\overline{{S}^{n}( {\mathcal H} )}}, with the 0 operator; if S is also left invertible, then {S}^{n} is similar to an operator B such that {d}_{{B}^{\ast },B}^{m}(I)=0. For power bounded S and T such that S{T}^{\ast }-{T}^{\ast }S=0 and {\text{Δ}}_{T,S}({S}^{\ast n}{S}^{n})=0, S is polaroid (i.e., isolated points of the spectrum are poles). The product property, and the perturbation by a commuting nilpotent property, of operators T,S satisfying {d}_{T,S}^{m}(I)=0, given certain commutativity properties, transfers to operators satisfying {S}^{\ast n}{d}_{T,S}^{m}(I){S}^{n}=0.

The local cohomology theory plays an important role in commutative algebra and algebraic geometry. The I-cofiniteness of local cohomology modules is one of interesting properties which has been studied by many mathematicians. The I-cominimax modules is an extension of I-cofinite modules which was introduced by Hartshorne. An R-module M is I-cominimax if Supp_R(M)\subseteq V(I) and Ext^i_R(R/I,M) is minimax for all i\ge 0. In this paper, we show some conditions such that the generalized local cohomology module H^i_I(M,N) is I-cominimax for all i\ge 0. We show that if H^i_I(M,K) is I-cofinite for all i<t and all finitely generated R-module K, then H^i_I(M,N) is I-cominimax for all i<t and all minimax R-module N. If M is a finitely generated R-module, N is a minimax R-module and t is a non-negative integer such that dim Supp_R(H^i_I(M,N))\le 1 for all i<t then H^i_I(M,N) is I-cominimax for all i<t. When dim R/I\le 1 and H^i_I(N) is I-cominimax for all i\ge 0 then H^i_I(M,N) is I-cominimax for all i\ge 0.

Abstract Let Bj (t) (j = 1,..., m) and B(t, τ) (t ≥ 0, 0 ≤ τ ≤ 1) be bounded variable operators in a Banach space. We consider the equation u ′ ( t ) = ∑ k = 1 m B k ( t ) u ( t - h k ( t ) ) + ∫ 0 1 B ( t , τ ) u ( t - h 0 ( τ ) ) d τ ( t ≥ 0 ) , u'\left( t \right) = \sum\limits_{k = 1}^m {{B_k}\left( t \right)u\left( {t - {h_k}\left( t \right)} \right)} + \int\limits_0^1 {B\left( {t,\tau } \right)u\left( {t - {h_0}\left( \tau \right)} \right)d\tau \,\,\,\,\left( {t \ge 0} \right),} where hk (t) (t ≥ 0; k = 1, ..., m) and h 0(τ) are continuous nonnegative bounded functions. Explicit delay-dependent exponential stability conditions for that equation are established. Applications to integro-differential equations with delay are also discussed

The evolution of a thin liquid film subject to a volatile solvent source and an air-blow effect which modifies locally the surface tension and leads to Marangoni-induced flow is shown to be governed by a degenerate fourth order nonlinear parabolic h-evolution equation of the type given by ∂ t h = − div x M 1 h ∂ x 3 h + M 2 h ∂ x h + M 3 h , where the mobility terms M 1 h and M 2 h result from the presence of the source and M 3 h results from the air-blow effect. Various authors assume M 2 h ≈ 0 and exclude the air-blow effect into M 3 h . In this paper, the authors show that such assumption is not necessarily correct, and the inclusion of such effect does disturb the dynamics of the thin film. These emphasize the importance of the full definition t → · grad γ = grad x γ + ∂ x h grad y γ of the surface tension gradient at the free surface in contrast to the truncated expression t → · grad γ ≈ grad x γ employed by those authors and the effect of the air-blow flowing over the surface.

The composite bucket foundation of offshore wind turbines is subjected to a variety of loads in the marine environment, such as horizontal load H, vertical load V , bending moment M, and torque T. In addition, due to the characteristics of its connection section, the water flow around the foundation will produce scour pits of various degrees, reducing the depth of the bucket foundation, which has a nonnegligible impact on the overall stability of the bucket foundation. In this paper, the failure envelope characteristics of different combinations of loads on bucket foundations, including V -H-T, V -M-T, conventional V -H-M, and noncoplanar V -H-M, are numerically investigated with considering different scour depths. The numerical results indicate that the V -H-T, V -M-T, conventional V -H-M, and noncongruent V -H-M failure envelopes gradually shrink inwards with increasing scour depth, and the stability of the composite bucket foundation decreases; the conventional V -H-M failure envelope shows an asymmetry of convexity to the right, and the noncongruent V -H-M failure envelope shows an asymmetry of outward convexity to the left and right. The corresponding mathematical expressions for the failure envelope are obtained through the normalized fitting process, which can be used to evaluate the stability of the bucket foundation based on the relative relationship between the failure envelope and the actual load conditions, which can provide practical guidance for engineering design.

The electrochemical and antioxidant properties of 5,10,15,20-tetrakis(3′-hydroxyphenyl)porphyrin ( H 2 T (m- OHPh ) P ) and 5,10,15,20-tetrakis(4′-hydroxyphenyl)porphyrin ( H 2 T (p- OHPh ) P ) were tested by the cyclic voltammetry (CV) method. It is shown that in dimethylsulfoxide (DMSO) the electroreduction processes of oxygen and porphyrins are under diffusion control. The electroreduction of H 2 T (m- OHPh ) P and H 2 T (p- OHPh ) P with potentials about -1 V are irreversible due to the chemical step (EC process) which leads to products with oxidation potentials about -0.5 V. Additionally in case of oxygen and porphyrin coreduction, both H 2 T (m- OHPh ) P and H 2 T (p- OHPh ) P influence the O 2•- electrosynthesis. The nonlinear dependence of the O 2•- peak current vs. porphyrin concentrations makes the available amperometric approach unsuitable for antioxidant activity estimation. To solve this problem, the coulometric parameters were calculated. The excellent linearity of the coulometric response of superoxide ion vs. porphyrins concentration was demonstrated for a wide concentration range. On the basis of coulometric responses, we constructed a parameter which separated the radical scavenging activity and variation of oxygen electroreduction. The superoxide scavenging activities of H 2 T (m- OHPh ) P and H 2 T (p- OHPh ) P were determined using the developed approach. The effect of OH group position on the superoxide scavenge activity is shown: H 2 T (p- OHPh ) P has a higher activity (slope = 0.75 L.mmol-1) than H 2 T (m- OHPh ) P (slope = 0.60 L.mmol-1).

У флорі України порядок Malvales уключає три родини – Cistaceae, Malvaceae (incl. Tiliaceae) та Thymelaeaceae. У складі родини Cistaceae – три роди: Cistus (C. tauricus), Fumana (incl. Fumanopsis) – 3 види та Helianthemum – 12 видів, з яких для двох кримських (H. lasiocarpum, H. ledifolium) необхідні нові підтвердження. Для України (Карпати) за літературними даними наводився ще один вид – H. alpestre (≡ Cistus alpestre), але, можливо, помилково. Суттєві номенклатурні зміни відбулися у роді Helianthemum. Зокрема, синонімами H. canum s. str. визнано H. creticola та H. georgicum, які наводяться у вітчизняній літературі як самостійні види. Helianthemum nitidum, що раніше наводився для Гірського Криму, виявився синонімом виду H. glabrum, а H. ovatum – синонімом H. chamaecistus. Синонімами H. rupifragum є H. cretaceum та H. cretophylum, які наводяться у вітчизняній літературі як окремі види. Родина Malvaceae, з включенням до її складу родини Tiliaceae, у флорі України представлена 16 родами (Abelmoschus, Abutilon, Alcea, Althaea, Anoda, Callianthe, Corynabution, Gossypium, Hibiscus, Kitaibelia, Malope, Malva (incl. Lavatera), Malvella, Ripariosida, Sida, Tilia) та 49 видами (разом із підвидами, дикорослими та культивованими рослинами). Alcea pallida визнано за синонім A. biennis, а A. і A. taurica – синоніми A. rugosa. Вид Althaea armeniaca наводиться для материкової частини України (окол. Одеси, острів Бірючий) та Криму (околиці Севастополя: Інкерман, Кача) можливо, помилково, замість A. officinalis. Синонімом Althaea armeniaca є A. taurinensis (nom. illeg.), а A. narbonensis визнано синонімом A. cannabina. З чотирьох видів роду Abutilon, які наводилися у попередньому виданні чеклісту, лише один автохтонний вид (A. theopharastii) залишено у роді Abutilon. Три інших види, що культивуються як декоративні рослини, уключені до складу інших родів: Callianthe darwinii (≡ Abutilon darwinii), Callianthe striata (= A. thompsonii) та Corynabution vitifolium (≡ A. vitifolium). До роду Malva уключено рід Lavatera, оскільки основна морфологічна ознака, за якою раніше розрізнялися роди (зрослі при основі листочки підчаші у Lavatera і вільні у Malva) виявилася не достатньою, щоб їх розрізняти. Це підтверджується також літературними молекулярно-філогенетичними даними. У флорі України рід Malva представлений 9 видами. Новим видом для України є M. alcea, який раніше у вітчизняних зведеннях не наводився. Синонімами M. sylvestris є M. ambigua і M. mauritiana, а M. chinensis, M. crispa, M. erecta, M. mohileviensis, M. pulchella, що раніше наводилися у вітчизняних флористичних роботах, зведені в синоніми M. verticillata. Вид Sida hermaphrodita, який іноді культивується в Україні як технічна (волокниста) і кормова рослина і заноситься на поля як буp’ян нині виділений з роду Sida в окремий монотипний рід Ripariosida (R. hermaphrodita). Він виявився філогенетично, біогеографічно і морфологічно ізольованим від інших видів роду Sida, що підтверджується недавно проведеними молекулярно-філогенетичними дослідженнями. Номенклатурні і таксономічні зміни відбулися у роді Tilia. Зокрема синонімами T. begoniifolia визнано T. caucasica і T. i ruprechtii. Синонімом T. × europaea є T. × vulgaris, а синонімами T. tomentosa – T. argentea і T. petiolaris. Новими таксонами, які раніше не наводилися у вітчизняних джерелах є T. dasystyla subsp. multriflora (= T. ledebourii), T. × euchlora (T. cordata × T. dasystyla), T. × moltkei (T. americana L. × T. tomentosa Moench), T. platyphyllos subsp. cordifolia. Родина Thymelaeaceae в Україні представлена двома родами (Daphne, Thymelaea) та 6 видами.

Let $R$ be a left (resp. right) $s$-unital ring and $m$ be a positive integer. Suppose that for each $y$ in $R$ there exist $J(t)$, $g(t)$, $h(t)$ in $Z[t]$ such that $x^m[x,y]= g(y)[x,y^2f(y)]h(y)$ (resp. $[x,y]x^m= g(y)[x,y^2f(y)]h(y))$ for all $x$ in $R$. Then $R$ is commutative (and conversely). Finally, the result is extended to the case when the exponent $m$ depends on the choice of $x$ and $y$.

Traditionally, models developed by Treynor and Mazuy (T-M) and also by Henriksson-Merton (H-M), which are called market-timing models, are applied to assess effectiveness of investment funds. The objective of the presented study is an application of the T-M and H-M models and their T-M-FF and H-M-FF modifications with additional Fama-French factors to assess effectiveness and risk of equity insurance connected with unit-linked insurance. Estimation and verification of the models for the subject group of equity funds were performed and the significance of the impact of particular factors on returns on reference portfolios was discussed.

Measurements of complex AC susceptibility were performed on Bi-2223/Bi-2212 high Tc superconductor at low excitation field amplitudes. Unusual features attributable to the Bi-2223 phase are observed in the imaginary part of the AC susceptibility, χ″(T), at different excitation field amplitudes, H m . The peak temperature, T p as a function of H m defines a region in (H, T) plane, where χ″ is independent of H m . Various possible interpretations are discussed, including that of a transition to a viscous flux flow regime.

For some operator A ? B(H), positive integers m and k, an operator T ? B(H) is called k-quasi-(A,m)-symmetric if T*k( mP j=0 (?1)j(m j )T*m?jATj)Tk = 0, which is a generalization of the m-symmetric operator. In this paper, some basic structural properties of k-quasi-(A,m)-symmetric operators are established with the help of operator matrix representation. We also show that if T and Q are commuting operators, T is k-quasi-(A,m)-symmetric and Q is n-nilpotent, then T + Q is (k + n ? 1)-quasi-(A,m + 2n ? 2)-symmetric. In addition, we obtain that every power of k-quasi-(A,m)-symmetric is also k-quasi-(A,m)-symmetric. Finally, some spectral properties of k-quasi-(A,m)-symmetric are investigated.

Host searching behavior of females of the endoparasitoid Toxoneuron nigriceps Vierick (Hymenoptera: Braconidae) was observed in the field for three tobacco herbivores, Heliothis virescens (F.), Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), and Manduca sexta L. (Lepidoptera: Sphingidae). The only developmentally suitable host for the parasitoid was H. virescens. Hovering, searching, and oviposition (for plants with herbivores) by T. nigriceps were observed for a combination of two plant types, plants with only herbivore-induced plant volatiles or damaged plants with herbivores, and three insect species. The six treatments were as follows: (1) plants with only H. virescens-induced plant volatiles, (2) plants with only H. zea-induced plant volatiles, (3) plants with only M. sexta-induced plant volatiles, (4) plants damaged by H. virescens, (5) plants damaged by H. zea, and (6) plants damaged by M. sexta. Parasitoid females readily hovered around and searched on plants of both types. However, females spent more time foraging for H. virescens than for the nonhosts, H. zea and M. sexta. For plants with only herbivore-induced plant volatiles, T. nigriceps females spent more time searching on H. virescens plants than on H. zea and M. sexta plants. For damaged plants, parasitoid females visited more H. virescens plants than M. sexta plants and spent more time searching for H. virescens larvae than for M. sexta and H. zea larvae. Even though T. nigriceps females laid eggs in M. sexta and H. zea larvae, oviposition was higher for H. virescens than for the nonhosts. In conclusion, T. nigriceps females utilized more of their energy searching for and parasitizing H. virescens over the nonhosts on tobacco.

Abstract This paper is devoted to the weak and strong estimates for the linear and multilinear fractional Hausdorff operators on the Heisenberg group H n {{\mathbb{H}}}^{n} . A sharp strong estimate for T Φ m {T}_{\Phi }^{m} is obtained. As an application, we derive the sharp constant for the product Hardy operator on H n {{\mathbb{H}}}^{n} . Some weak-type ( p , q ) \left(p,q) ( 1 ≤ p ≤ ∞ ) \left(1\le p\le \infty ) estimates for T Φ , β {T}_{\Phi ,\beta } are also obtained. As applications, we calculate some sharp weak constants for the fractional Hausdorff operator on the Heisenberg group. Besides, we give an explicit weak estimate for T Φ , β → m {T}_{\Phi ,\overrightarrow{\beta }}^{m} under some mild assumptions on Φ \Phi . We extend the results of Guo et al. [Hausdorff operators on the Heisenberg group, Acta Math. Sin. (Engl. Ser.) 31 (2015), no. 11, 1703–1714] to the fractional setting.

The differential susceptibility of two termite species, Macrotermes bellicosus and Trinervitermes occidentalis, to four entomopathogenic nematodes (EPN) isolates from Benin, Heterorhabditis indica Ayogbe1, H. sonorensis Azohoue2, H. sonorensis Ze3 and Steinernema sp. Bembereke, was bio-assayed in laboratory tests. Soldiers of both M. bellicosus and T. occidentalis were similarly susceptible, but more susceptible than workers. Forty-eight h post-exposure of workers of M. bellicosus to 50 infective juveniles (IJ) of H. indica Ayogbe1, H. sonorensis Azohoue2, H. sonorensis Ze3 and Steinernema sp. Bembereke for each termite resulted in 96.3, 87.9, 94.5 and 75.0% mortality, respectively, whereas under the same conditions, these EPN isolates caused 91.7, 98.5, 75.0 and 95.0% mortality of workers of T. occidentalis. Soldiers of M. bellicosus were the most invaded with 13.2-18.6% of applied IJ. Based on concentration-mortality data, the isolates H. indica Ayogbe1 and H. sonorensis Ze3 were more virulent to M. bellicosus with LC50 values of 11 IJ, whereas Steinernema sp. Bembereke was the most virulent to T. occidentalis with LC50 values of 12 IJ. However, none of these isolates showed the highest penetration rate. All tested EPN isolates can recycle in both M. bellicosus and T. occidentalis. Our EPN repellent-dispersing assay did not show evidence that M. bellicosus and T. occidentalis would be able to detect the presence of IJ of any EPN isolates/species. However, it was observed that nematode dispersal occurred by infected termites or phoresis.

A harmonious colouring of a simple graph G is a proper vertex colouring such that each pair of colours appears together on at most one edge. The harmonious chromatic number h(G) is the least number of colours in such a colouring.For any positive integer m, let Q(m) be the least positive integer k such that ≥ m. We show that for almost all unlabelled, unrooted trees T, h(T) = Q(m), where m is the number of edges of T.

Here in this paper, we are using the concepts of q -calculus operator theory associated with harmonic functions and define the q -Noor integral operator for harmonic functions f ∈ H 0 . We investigate a new class S H 0 m , q , α of harmonic functions f ∈ H 0 . In this class, we prove a necessary and sufficient convolution condition for the functions f ∈ H 0 and also we proved that this sufficient coefficient condition is sense preserving and univalent in the class S H 0 m , q , α . It is proved that this coefficient condition is necessary for the functions in its subclass T S H 0 m , q , α . By using this necessary and sufficient coefficient condition, we obtained results based on the convexity and compactness and results on the radii of q -starlikeness and q -convexity of order α in the class T S H 0 m , q , α . Also we obtained extreme points for the functions in the class T S H 0 m , q , α .

Cerebrovascular dilation over PaO2 ranging from hyperoxia to moderate hypoxia is unexplained. We hypothesize that tissue acidosis is the cause. Local cortical cerebral blood flow (LCBF), tissue hydrogen ion concentration [H+]t, and tissue Po2 (Pto2) were measured with microelectrodes in the parietal cortex of 18 rats during a 30-min steady state on 60 to 10% inspired O2 (Pao2, 300 to 40 torr) during 40% N2O analgesia. Five rats kept on 60% O2/40% N2O served as controls. In 18 rats at a Pao2 of 275 ± 7 torr (X̄ ± SEM) and Paco2 of 35 ±1 torr, cerebral values were: LCBF = 129 ± 23 (X̄ ± SEM) ml · 100 g−1 · min−1; [H+], = 62 ± 6 n M; and Pto2 = 25 ± 3 torr. As Pao2 was reduced from about 300 to 40 torr, changes in these variables in percentage of control with respect to Pao2, were described by the following equations, all at P < 0.0001: LCBF = 85.9 + 5,572/Pao2; [H+]t = 97.15 + 1,012/Pao2; and = 108.8 − 3,492/Pao2. Simultaneous solution of the LCBF and [H+]t equations at various Pao2 revealed a slope of 8.82%/n M. Direct correlation between LCBF in ml · 100 g−1 · min−1 and [H+]t in n M revealed a linear relationship defined by the equation Y = − 7.472 + 1.6705 X ( r = 0.6426) for [H+]t between 56 and 160 n M (pH = 7.25 and 6.80) but no correlation at [H+]t values between 56 and 32 n M (pH = 7.25 to 7.50). Cerebrovascular tone is directly correlated with [H+]t during progressive, 30-min steady-state reduction in Pao2 from 350 to 40 torr.

Abstract We derive and publish data-driven estimates of stellar metallicity [M/H] for ∼175 million stars with low-resolution XP spectra published in Gaia DR3. The [M/H] values, along with T eff and log g , are derived using the XGBoost algorithm, trained on stellar parameters from APOGEE, augmented by a set of very-metal-poor stars. XGBoost draws on a number of data features: the full set of XP spectral coefficients, narrowband fluxes derived from XP spectra, and broadband magnitudes. In particular, we include CatWISE magnitudes, as they reduce the degeneracy of T eff and dust reddening. We also include the parallax as a data feature, which helps constrain log g and [M/H]. The resulting mean stellar parameter precision is 0.1 dex in [M/H], 50 K in T eff, and 0.08 dex in log g . This all-sky [M/H] sample is substantially larger than published samples of comparable fidelity across −3 ≲ [M/H] ≲ +0.5. Additionally, we provide a catalog of over 17 million bright (G < 16) red giants whose [M/H] values are vetted to be precise and pure. We present all-sky maps of the Milky Way in different [M/H] regimes that illustrate the purity of the data set, and demonstrate the power of this unprecedented sample to reveal the Milky Way’s structure from its heart to its disk.

In this work, top-configuration exchange-biasing NiFe ( y )/ IrMn (90Å) systems have been investigated with three different conditions: (a) the substrate temperature ( T s ) was kept at room temperature (RT) only, (b) T s at RT with an in-plane field ( h ) = 500 Oe deposition during deposition, and (c) T s = RT with h during deposition and postdeposition annealing in the field at T A = 250° C for 1h, with the samples field cooled to RT. High resolution electron cross-sectional transmission electron microscopy (HR X-TEM) and x-ray results reveal that the IrMn (111) texturing plays a key role in the exchange-biasing field ( H ex ) and interfacial energy ( J k ). The H ex versus y result shows that H ex increases when y decreases. Since J k = H ex M s y , where M s is NiFe magnetization, it is easy to derive H ex = J k /( M s y ). Therefore, if H ex is inversely proportional to y , with J k / M s constant, we find H ex y = constant. In short, the y dependence of J k is similar to that of M s for each curve. The H c is inversely proportional to y because of the surface pinning effects from the Ta / NiFe and NiFe / IrMn interfaces. Finally, the optimal values for H ex and J k are 220 Oe and 0.075 erg/cm2, respectively.

The effects of 7-[[4-[bis(4-fluoropheny l ) - m e t h y l ] - 1 - p i p e r a z i n y l ] m e t h y l ] - 2 - [ ( 2 - h y d r o x y e t h y l ) a m i n o ]4 -( 1 - m e t h y l e t h y l ) - 2 , 4 , 6 - c y c l o h e p t a t r i e n - 1 - o n e ( U - 9 2 0 3 2 ) , anewly described Ca2+ channel blocker, on voltage-gated ionic currents were measured. Whole cell voltage-clamp records were obtained from acutely isolated CA1 hippocampal pyramidal neurons from 7- to 14-day-old rats. Dimethyl sulfoxide, at either 0.01% or 0.1%, partially inhibited T-type Ca2+ currents (∼20% inhibition) but not high-voltage-activated (HVA) Ca2+ currents. Ethanol (0.2%) did not affect Ca2+ currents. U-92032 selectively inhibited T-type Ca2+ currents (median inhibiting concentration ∼ 500 nM). HVA Ca2+ currents were less sensitive, with ∼75% of the current resistant at 10 μM. Inhibition of Ca2+ currents was reversible. U-92032 inhibited Na+ currents at concentrations similar to those required for T-type currents (>33% block at 1 μM). Block of Na+ currents took several minutes to develop and was irreversible. Voltage-gated K+ currents were insensitive to U-92032 (1 or 10 μM). These results indicate that U-92032 inhibits both T-type Ca2+ channels and Na+ channels, constraining its utility in certain studies. Among Ca2+ channels, however, U-92032 should prove a useful tool for distinguishing physiological contributions of T-type channels.

In this paper we study skew m-complex symmetric operators. In particular, we show that if T ? L(H) is a skew m-complex symmetric operator with a conjugation C, then eitT , e-itT , and e-itT* are (m,C)-isometric for every t ? R. Moreover, we examine some conditions for skew m-complex symmetric operators to be skew (m-1)-complex symmetric.
