Curvature invariant characterization of event horizons of four-dimensional black holes conformal to stationary black holes

Year: 2017

subject: FOS: Physical sciences

description: We introduce three approaches to generate curvature invariants that transform covariantly under a conformal transformation of a four dimensional spacetime. For any black hole conformally related to a stationary black hole, we show how a set of conformally covariant invariants can be combined to produce a conformally covariant invariant that detects the event horizon of the conformally related black hole. As an application we consider the rotating dynamical black holes conformally related to the Kerr-NUT-(Anti)-de Sitter spacetimes and construct an invariant that detects the conformal Killing horizon along with a second invariant that detects the conformal stationary limit surface. In addition, we present necessary conditions for a dynamical black hole to be conformally related to a stationary black hole and apply these conditions to the ingoing Kerr-Vaidya and Vaidya black hole solutions to determine if they are conformally related to stationary black holes for particular choices of the mass function. While two of the three approaches cannot be generalized to higher dimensions, we discuss the existence of a conformally covariant invariant that will detect the event horizon for any higher dimensional black hole conformally related to a stationary black hole which admits at least two conformally covariant invariants, including all vacuum spacetimes.

Collective phases of identical particles interfering on linear multiports

description: We introduce collective geometric phases of bosons and fermions interfering on a linear unitary multiport, where each phase depends on the internal states of identical particles (i.e., not affected by the multiport) and corresponds to a cycle of the symmetric group. We show that quantum interference of $N$ particles in generic pure internal states, i.e., with no pair being orthogonal, is governed by $(N-1)(N-2)/2$ independent triad phases (each involving only three particles). The deterministic distinguishability, preventing quantum interference with two or three particles, allows for the genuine $(N\ge 4)$-particle phase (interference) on a multiport: setting each particle to be deterministically distinguishable from all others except two by their internal states allows for a novel (circle-dance) interference of $N\ge 4$ particles governed by a collective $N$-particle phase, while simultaneously preventing the $R$-particle interference for $3\le R\le N-1$. The genuine $N$-particle interference manifests the $N$th order quantum correlations between identical particles at a multiport output, it does not appear in the marginal probability for a subset of the particles, e.g., it cannot be detected if at least one of the particles is lost. This means that the collective phases are not detectable by the usual "quantumness" criteria based on the second-order quantum correlations. The results can be useful for quantum computation, quantum information, and other quantum technologies with single photons. \end{abstract}

description: The study reports the production of an innovative functional orange powder supplemented with probiotics and prebiotics, by implementing new ecofriendly and sustainable technologies, such as spray drying. The survival of Lactobacillus casei shirota, Lactobacillus casei immunitas and Lactobacillus acidophilus johnsonii, during spray drying in orange juice was proven and the stability of the powder obtained at room temperature and at 4 °C was investigated. Furthermore, the study highlighted the possibility to enhance the pectin obtained from the food agroindustry as a carrier for the spray-drying process. Combining maltodextrins and pectins at a 10:1 weight ratio. The study showed the efficiency of the maltodextrin/pectin mixture as carriers for the spray-drying process and the viability of the tested microorganisms during both the storage at room temperature and at 4 °C, showing that the latter represents the best storing condition for a longer viability of the microorganisms.

description: We complement the theory developed in Preinerstorfer and Pötscher (2016) with further finite sample results on size and power of heteroskedasticity and autocorrelation robust tests. These allows us, in particular, to show that the sufficient conditions for the existence of size-controlling critical values recently obtained in Pötscher and Preinerstorfer (2018) are often also necessary. We furthermore apply the results obtained to tests for hypotheses on deterministic trends in stationary time series regressions, and find that many tests currently used are strongly size-distorted.

Braids with as many full twists as strands realize the braid index

description: We characterize the fractional Dehn twist coefficient of a braid in terms of a slope of the homogenization of the Upsilon function, where Upsilon is the function-valued concordance homomorphism defined by Ozsváth, Stipsicz, and Szabó. We use this characterization to prove that $n$-braids with fractional Dehn twist coefficient larger than $n-1$ realize the braid index of their closure. As a consequence, we are able to prove a conjecture of Malyutin and Netsvetaev stating that $n$-times twisted braids realize the braid index of their closure. We provide examples that address the optimality of our results. The paper ends with an appendix about the homogenization of knot concordance homomorphisms.

description: Emerging evidence on the potential pro-oxidant effect of carotenoids provokes apoptosis of cancer cells. Bixa orellana L. is native to Central and South America, interestingly, is also cultivated worldwide. Apo-carotenoids present in B. orellana L. are mainly dominated by bixin and norbixin and demonstrate fundamental antioxidant activity. Anti-proliferative activity on human cancer cells is rarely investigated. We isolated bixin from B. orellana L. found in the island of Java using Ultra-Fast Liquid Chromatography and confirmed the isolated compound using Liquid Chromatography-MS/MS. Bixin and crude extract were examined on human lung cancer (A549), cervical cancer (HeLa), and breast cancer (MCF-7). Anti-proliferative activity revealed to be promising on both, the isolated pigment and crude extract. Further investigation on the mechanism of action and effect on other cell lines, both in vitro and in vivo, are required before clinical translation.
Effective mobility for sequential carrier transport in multiple quantum well structures

description: We investigate a theoretical model for effective carrier mobility to comprehensively describe the behavior of the perpendicular carrier transport across multiple quantum well (MQW) structures under applied electric field. The analytical expressions of effective mobilities for thermionic emission, direct tunneling, and thermally-assisted tunneling are derived based on the quasi-thermal equilibrium approximation and the semi-classical approach. Effective electron and hole mobilities in InGaAs/GaAsP MQWs predicted from our model are in good agreement with the experimental results obtained from the carrier time-of-flight measurement near room temperature. With this concept, the complicated carrier dynamics inside MQWs can be simplified to an effective mobility, an equivalent parameter which is more straightforward to handle and can be easily incorporated in the conventional drift-diffusion model.

description: Lepra, nicht was Du denkst ist das Motto des Welt-Lepra-Tages am 27. Januar 2020. Vor nunmehr 20 Jahren vermeldete die WHO, dass Lepra weltweit eliminiert wurde. Zwar gab es beachtliche Erfolge in der Zurückdrängung der Lepra, doch auch heute werden weltweit ca. alle zwei Minuten neue Patienten mit Lepra diagnostiziert. Vor vier Jahren hat die WHO die Globale Leprastrategie 2016 – 2020 „Beschleunigung zu einer Lepra-freien Welt“ verabschiedet. Diese beinhaltet drei zentrale Ziele, die u. a. Grad-2-Behinderungen, Fälle bei Kindern oder Diskriminierungen von Erkrankten betreffen. Dieses Ziel gilt es bis 2020 zu erreichen. Wie das Epidemiologische Bulletin 4/2020 berichtet, werden sie nach aktuellem Kenntnisstand nicht erreicht werden können. Experten sind deshalb zu dem Schluss gelangt, dass neue Initiativen und innovative Ansätze benötigt werden, um die bestehenden Herausforderungen anzugehen und die Triple-Zero-Ziele der Globalen Leprastrategie (Keine Ansteckung – Keine Behinderung – Keine Diskriminierung) zur Realität werden zu lassen.

description: The spectral radius of a graph is the largest eigenvalue of its adjacency matrix. Let $\mathcal{F}(λ)$ be the family of connected graphs of spectral radius $\le λ$. We show that $\mathcal{F}(λ)$ can be defined by a finite set of forbidden subgraphs if and only if $λ< λ^* := \sqrt{2+\sqrt{5}} \approx 2.058$ and $λ\not\in \{α_2, α_3, \dots\}$, where $α_m = β_m^{1/2} + β_m^{-1/2}$ and $β_m$ is the largest root of $x^{m+1}=1+x+\dots+x^{m-1}$. The study of forbidden subgraphs characterization for $\mathcal{F}(λ)$ is motivated by the problem of estimating the maximum cardinality of equiangular lines in the $n$-dimensional Euclidean space $\mathbb{R}^n$ --- a family of lines through the origin such that the angle between any pair of them is the same. Denote by $N_α(n)$ the maximum number of equiangular lines in $\mathbb{R}^n$ with angle $\arccosα$. We establish the asymptotic formula $N_α(n) = c_αn + O_α(1)$ for every $α\ge \frac{1}{1+2λ^*}$. In particular, $N_{1/3}(n) = 2n+O(1)$ and $N_{1/5}(n), N_{1/(1+2\sqrt{2})}(n) = \frac{3}{2}n+O(1)$. Besides we show that $N_α(n) \le 1.49n + O_α(1)$ for every $α\neq \tfrac{1}{3}, \tfrac{1}{5}, \tfrac{1}{1+2\sqrt{2}}$, which improves a recent result of Balla, Dräxler, Keevash and Sudakov.

description: Muons can be created in nascent neutron stars (NSs) due to the high electron chemical potentials and the high temperatures. Because of their relatively lower abundance compared to electrons, their role has so far been ignored in numerical simulations of stellar core collapse and NS formation. However, the appearance of muons softens the NS equation of state, triggers faster NS contraction and thus leads to higher luminosities and mean energies of the emitted neutrinos. This strengthens the postshock heating by neutrinos and can facilitate explosions by the neutrino-driven mechanism.

Heterogeneous Investment to Enhance a Common Pool Resource

Subjects: subject: Social and Behavioral Sciences

description: This project uses theory and experiments to examine a common pool resource that can be enhanced with effort. The specific interest is to examine individual and group appropriation when effort is shared or not shared among group members. Also, we consider cases when the unequal effort is exogenously and endogenously determined (voluntary or not). Theory is developed with standard theoretical predictions unaffected by the effort frames. However, the literature indicates the potential for the effort frame to influence behavior. Thus, experiments are conducted to test the theoretical predictions. Using a dynamic CPR game, we plan for four experimental treatments: no effort baseline, equally shared exogenously determined effort, unequally shared exogenously determined effort, unequally shared endogenously determined effort.

description: Brundan, Kleshchev and Wang equip the Specht modules $S_λ$ over the cyclotomic Khovanov--Lauda--Rouquier algebra $\mathscr{H}_n^Λ$ with a homogeneous $\mathbb{Z}$-graded basis. In this paper we begin the study of graded Specht modules labelled by hook bipartitions $((n-m),(1^m))$ in level $2$ of $\mathscr{H}_n^Λ$, which are precisely the Hecke algebras of type B, with quantum characteristic at least three. We give an explicit description of the action of the Khovanov--Lauda--Rouquier algebra generators $ψ_1,\dots,ψ_{n-1}$ on the basis elements of $S_{((n-m),(1^m))}$. Introducing certain Specht module homomorphisms, we construct irreducible submodules of these Specht modules, and thereby completely determining the composition series of Specht modules labelled by hook bipartitions for $e\geqslant{3}$.

description: Two new tetrahydrofuran lignans 1-2, along with 2,3-seco-lup-20(29)-en-2,3-dioic acid (3), (–)-larreatricin (4), and 15 additional compounds were isolated from Combretum mellifluum (Combretaceae). Their structures were determined by 1D- and 2D- NMR spectroscopic data and HRESIMS. Another 15 compounds were identified after HPLC-DAD-MS/MS analysis. Tested against HT-29 (colon) neoplastic cells, lignan 1 showed marked cytotoxicity (GI50 = 3.9 µM) and high selectivity (SI > 227), compared with non-neoplastic NIH/3T3 cells, while 2 proved less cytotoxic, despite exhibiting SI > 75. Seco-triterpene 3 was strongly cytotoxic to 786-0 (kidney) and HT-29 cells (GI50 = 0.5 and 2.9 µM, respectively), proving roughly 107 and 18 times more selective for these cell lines, respectively, than for NIH/3T3 cells. After 48 h of incubation, 1-3 exhibited potent cytostatic activity against HT-29 cells at all concentrations tested, while 3 had a cytocidal effect on 786-0 cells at 25 µg.mL−1.

description: A nonlinear unified fluid model that describes the Equatorial Electrojet, including the Farley-Buneman and gradient-drift plasma instabilities, is defined and shown to be a noncanonical Hamiltonian system. Two geometric constants of motion for the model are obtained and shown to be Casimir invariants. A reformulation of the model shows the roles of the density-gradient scale-length ($L_n$) and the cross-field drift-velocity (${\upsilon}_E$) in controlling the dynamics of unstable modes in the growing, transition, and saturation phases of a simulation.
The fractional Calderón problem: low regularity and stability

Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: The Calderón problem for the fractional Schrödinger equation was introduced in the work \cite{GSU}, which gave a global uniqueness result also in the partial data case. This article improves this result in two ways. First, we prove a quantitative uniqueness result showing that this inverse problem enjoys logarithmic stability under suitable a priori bounds. Second, we show that the results are valid for potentials in scale-invariant $L^p$ or negative order Sobolev spaces. A key point is a quantitative approximation property for solutions of fractional equations, obtained by combining a careful propagation of smallness analysis for the Caffarelli-Silvestre extension and a duality argument.

description: Given a quantum heat engine that operates in a cycle that reaches maximal efficiency for a time-dependent Hamiltonian H(t) of the working substance, with overall controllable driving H(t) = g(t) H, we study the deviation of the efficiency from the optimal value due to a generic time-independent perturbation in the Hamiltonian. We show that for a working substance consisting of two two-level systems, by suitably tuning the interaction, the deviation can be suppressed up to the third order in the perturbation parameter-and thus almost retaining the optimality of the engine.

description: Ancestral character reconstructions of orbit convergence and visual acuity in mammals. The phylogenetic association between each variable and the opsin ω-tree was tested using the Moran’s I hypothesis test (p-value <0.003, Bonferroni corrected for 16 comparisons). Ancestral character reconstructions were performed using the Brownian motion model, excluding the cases in which none (*) or only one (**) species was representing the clades of interest (mammalia, monotremata, eutheria, marsupialia, placentalia). Inferences for each opsin (mean and standard deviation) are shown for each opsin gene tree. The last line of the table summarizes the results considering the mean probability distribution.

description: We introduce the coherent state mapping ring-polymer molecular dynamics (CS-RPMD), a new method that accurately describes electronic non-adiabatic dynamics with explicit nuclear quantization. This new approach is derived by using coherent state mapping representation for the electronic degrees of freedom (DOF) and the ring-polymer path-integral representation for the nuclear DOF. CS-RPMD Hamiltonian does not contain any inter-bead coupling term in the state-dependent potential, which is a key feature that ensures correct electronic Rabi oscillations. Hamilton's equation of motion is used to sample initial configurations and propagate the trajectories, preserving the distribution with classical symplectic evolution. In the special one-bead limit for mapping variables, CS-RPMD preserves the detailed balance. Numerical tests of this method with a two-state model system show a very good agreement with exact quantum results over a broad range of electronic couplings.
A mathematical model for DNA

description: Recently, some authors have shown that a DNA molecule produces electromagnetic signals and communicates with other DNA molecules or other molecules. In fact, a DNA acts like a receiver or transmitter of radio waves. In this paper, we suggest a mathematical model for the DNA molecule and use of its communication to cure some diseases like cancer. In this model, first, by using concepts from string theory and M-theory, we calculate the energy of a DNA in terms of interactions between free electrons and bound electrons. We show that when a DNA is damaged, its energy changes and an extra current is produced. This extra current causes the electromagnetic signals of a damaged DNA molecule to be different when compared to the electromagnetic signals of a normal DNA molecule. The electromagnetic signals of a damaged DNA molecule induces an extra current in a normal DNA molecule and leads to its destruction. By sending crafted electromagnetic signals to normal DNA molecules and inducing an opposite current with respect to this extra current, we can prevent the destruction of normal DNA. Finally, we argue that the type of packing of DNA in chromosomes of men and women are different. This causes radiated waves from DNAs of men and women to have opposite signs and cancel the effect of each other in a pair. Using this property, we suggest another mechanism to cancel the effect of extra waves, which are produced by DNAs in cancer cells of a male or a female, by extra waves which are produced by DNAs in similar cells of a female or a male and prevent the progression of the disease.

description: Bioassay-guided fractionation of dichloromethane extract from Athenaea velutina leaves led to the isolation of three withanolides, all being reported for the first time in this species. They were identified as withacnistin (1), withacnistin acetate (2) and a new withanolide, designated as withalutin (3). The structures were established by spectral data analysis, including MS, 1D and 2D NMR. In addition, in silico ADMET studies were employed to understand the pharmacokinetic properties of these withanolides. The withanolides isolated from A. velutina reduced cancer cell viability with IC50 values ranging from 1.52 to 5.39 µM. In silico prediction revealed that withanolides have good gastrointestinal absorption or oral bioavailability properties; and are not likely to be mutagenic or hepatotoxic. These findings revealed that A. velutina is an important source of cytotoxic withanolides.

description: Dipeptidyl-peptidase-4 is a multifunctional ectoenzyme, which is implicated with hyperglycemic pathophysiology. Therefore, dipeptidyl-peptidase-4 inhibitors could be used as an attractive therapeutic strategy in blood-glucose homeostasis to attenuate the pathophysiologies of diabetes. A sulfated galactofucan characterized as [→1)-O-4-sulfonato-α-fucopyranosyl-(2→1)-O-2-sulfonato-α-fucopyranose-(3→] along with a branch of [→1)-6-O-methyl-β-galactopyranosyl-(4→] unit at the C-4 position of O-2-sulfonato-α-fucopyranose, isolated from the seaweed Padina tetrastromatica, exhibited prospective attenuation property against dipeptidyl-peptidase-4 (IC50 0.25 mg mL−1). The studied sulfated galactofucan exhibited potential inhibitory properties against carbolytic enzymes α-amylase (IC50 0.98 mg mL−1) and α-glucosidase (IC50 0.87 mg mL−1) in comparison with the standard antidiabetic agent acarbose, along with radical scavenging activities. The seaweed-originated galactofucan could be developed as a promising natural therapeutic lead against hyperglycemic disorder.

description: We consider variants of trust-region and cubic regularization methods for non-convex optimization, in which the Hessian matrix is approximated. Under mild conditions on the inexact Hessian, and using approximate solution of the corresponding sub-problems, we provide iteration complexity to achieve $ ε$-approximate second-order optimality which have shown to be tight. Our Hessian approximation conditions constitute a major relaxation over the existing ones in the literature. Consequently, we are able to show that such mild conditions allow for the construction of the approximate Hessian through various random sampling methods. In this light, we consider the canonical problem of finite-sum minimization, provide appropriate uniform and non-uniform sub-sampling strategies to construct such Hessian approximations, and obtain optimal iteration complexity for the corresponding sub-sampled trust-region and cubic regularization methods.

description: Adenanthera pavonina L. has been used traditionally to relieve inflammation. This study aimed to expand the phytochemical knowledge of A. pavonina and evaluate its constituents for their antioxidant and anti-inflammatory potentials as tumor necrosis factor alpha (TNF-α) inhibitors. The antioxidant activity was evaluated using the DPPH radical scavenging assay, and the inhibition of TNF-α was assessed through ELISA and qRT-PCR techniques. Interestingly, five previously undescribed metabolites, including a pentadienoic acid derivative, a triterpenoid glycoside, and three tamarixetin glycosides, were identified alongside seven known compounds. Most compounds evaluated had higher DPPH radical scavenging capabilities than the standard, trolox. Tamarixetin 3-O-(α-ʟ-rhamnopyranosyl)-(1→2)-β-ᴅ-galactopyranoside (11), a previously undescribed compound, was the most effective at suppressing TNF-α protein and m-RNA levels. Other flavonoid glycosides, quercetin 3-O-(α-ʟ-rhamnopyranosyl-(1→2)-β-ᴅ-xylopyranoside (4), isovitixin (5), and quercetin-3-O-[α-ʟ-rhamnopyranosyl-(1→2)]-[α-ʟ-rhamnopyranosyl-(1→6)]-β-ᴅ-galactopyranoside (9), also significantly lowered TNF-α production.

description: Five metabolites (1–5), including two new sesquiterpenoids, designated ganodermanol L (1) and 4α,15-epoxyeudesmane-1β,6α,11-triol (2), together with three known structurally related compounds (3-5), have been isolated from the cultures of Streptomyces sp. XM17, a bacteria residing in the fresh feces of the giant panda Ailuropoda melanoleuca. The structures of 1–2 were established on the basis of extensive spectroscopic analyses, including 1D- and 2D-NMR (1H-1H COSY, HMQC, HMBC and NOESY) experiments. Furthermore, the absolute configuration of 1 was established by single-crystal X-ray crystallographic analyses. Of noted, these compounds were found to possessed antiviral activities using the ‘pretreatment of virus’ approach with IC50 values ranging from 4 to 30 nM, indicating that these sesquiterpenoids were potent in inhibiting the entry of influenza A virus.
