description: Recent observations of the Rho Ophiuchi cluster with the Herschel Space Observatory allow us to probe the spectral energy distribution (SED) of the brown dwarf population in the far-IR, where the disk emission peaks. We performed aperture photometry at 70, 100, and 160 micron, and constructed SEDs for all previously known brown dwarfs detected. These were complemented with ancillary photometry at shorter wavelengths. We compared the observed SEDs to a grid of synthetic disks produced with the radiative transfer code MCFOST, and used the relative figure of merit estimated from the Bayesian inference of each disk parameter to analyse the structural properties. We detected 12 Class II brown dwarfs with Herschel, which corresponds to one-third of all currently known brown dwarf members of Rho Ophiuchi. We do not detect any of the known Class III brown dwarfs. Comparison to models reveals that the disks are best described by an inner radius between 0.01 and 0.07 AU, and a flared disk geometry with a flaring index between 1.05 and 1.2. Furthermore, we can exclude values of the disk scale-height lower than 10 AU (measured at a fiducial radius of 100 AU). We combined the Herschel data with recent ALMA observations of the brown dwarf GY92 204 (ISO-Oph 102), and by comparing its SED to the same grid of disk models, we derived an inner disk radius of 0.035 AU, a scale height of 15 AU with a flaring index of beta~1.15, an exponent for dust settling of -1.5, and a disk mass of 0.001 MSun. This corresponds to a disk-to-central object mass ratio of ~1%. The structural parameters constrained by the extended SED coverage (inner radius and flaring index) show a narrow distribution for the 11 young brown dwarfs detected in Rho Ophiuchi, suggesting that these objects share the same disk evolution and, perhaps, formation.

description: Let $\mathcal{P}$ be a closed path having no zig-zag walks, a kind of non-simple thin polyomino. In this paper we give a combinatorial interpretation of the $h$-polynomial of $K[\mathcal{P}]$, showing that it is the rook polynomial of $\mathcal{P}$. It is known by Rinaldo and Romeo (2021), that if $\mathcal{P}$ is a simple thin polyomino then the $h$-polynomial is equal to the rook polynomial of $\mathcal{P}$ and it is conjectured that this property characterizes all thin polyominoes. Our main demonstrative strategy is to compute the reduced Hilbert-Poincaré series of the coordinate ring attached to a closed path $\mathcal{P}$ having no zig-zag walks, as a combination of the Hilbert-Poincaré series of convenient simple thin polyominoes. As a consequence we prove that the Krull dimension is equal to $\vert V(\mathcal{P})\vert -\mathrm{rank}\, \mathcal{P}$ and the regularity of $K[\mathcal{P}]$ is the rook number of $\mathcal{P}$. Finally we characterize the Gorenstein prime closed paths, proving that $K[\mathcal{P}]$ is Gorenstein if and only if $\mathcal{P}$ consists of maximal blocks of length three.

description: We demonstrate a new spectroscopic method for studying electronic transitions in molecules with extremely broad range of angular momentum. We employ an optical centrifuge to create narrow rotational wave packets in the ground electronic state of $^{16}$O$_2$. Using the technique of resonance-enhanced multi-photon ionization, we record the spectrum of multiple ro-vibrational transitions between $X^3Σ_{g}^{-}$ and $C^3Π_{g}$ electronic manifolds of oxygen. Direct control of rotational excitation, extending to rotational quantum numbers as high as $N\gtrsim 120$, enables us to interpret the complex structure of rotational spectra of $C^3Π_{g}$ beyond thermally accessible levels.

The general-purpose relativistic atomic structure package (GRASP) has been adopted for our calculations. Comparisons are made with the most recent results of Mohan et al. [Can. J. Phys. {\bf 92} (2014) xxx] and discrepancies in lifetimes are noted, up to four orders of magnitude in some instances. Our energy levels are estimated to be accurate to better than 0.5\%, whereas results for radiative rates and lifetimes should be accurate to better than 20\%.

Programming of channels in generalized probabilistic theories

description: For a given target system and apparatus described by quantum theory, the so-called quantum no-programming theorem indicates that a family of states called programs in the apparatus with a fixed unitary operation on the total system programs distinct unitary dynamics to the target system only if the initial programs are orthogonal to each other. The current study aims at revealing whether a similar behavior can be observed in generalized probabilistic theories (GPTs). Generalizing the programming scheme to GPTs, we derive a similar theorem to the quantum no-programming theorem. We furthermore demonstrate that programming of reversible dynamics is related closely to a curious structure named a quasi-classical structure on the state space. Programming of irreversible dynamics, i.e., channels in GPTs is also investigated.
Synchrotron and inverse-Compton emission from blazar jets - IV. BL Lac type blazars and the physical basis for the blazar sequence

description: In this paper we investigate the properties of a sample of six BL Lacs by fitting their spectra using our inhomogeneous jet model with an accelerating, magnetically dominated, parabolic base, which transitions to a slowly decelerating conical jet with a geometry based on observations of M87. Our model is able to fit very well to the simultaneous multiwavelength spectra of all the BL Lacs including radio observations. We find that the BL Lacs have lower jet powers and bulk Lorentz factors than the sample of Compton-dominant blazars investigated in Paper III, consistent with the blazar sequence. Excitingly, we find a correlation between the radius at which the jet first comes into equipartition and the jet power, in agreement with our prediction from Paper II. We interpret this result as one of two physical scenarios: a universal jet geometry which scales linearly with black hole mass or a dichotomy in Eddington accretion rates between flat spectrum radio quasars (FSRQs) and BL Lacs. If we assume that the jet geometry of all blazars scales linearly with black hole mass then we find a plausible range of masses (10^7-10^10 solar masses). We find that the quiescent gamma-ray spectrum of Markarian 421 is best fitted by scattering of external CMB photons. We are unable to fit the spectrum using synchrotron self-Compton emission due to strong gamma-ray absorption via pair production even using a compact, rapidly decelerating, jet with a very large bulk Lorentz factor (50), as has been suggested recently. Finally, we fit to the SEDs of the four high power HSP BL Lacs recently found by Padovani et al. 2012. We find that their high peak frequency emission is caused by high maximum electron energies whilst the rest of their jet properties are typical of relatively high power BL Lacs and consistent with our predictions.

description: Hops (Humulus lupulus) was used to treat menopausal symptoms because it contains phytoestrogens. Since these compounds prevent cardiac ischemic diseases, it was evaluated whether oral administration of an ethanol extract (Hops-T) to rats during a week could reduce cardiac post-ischemic dysfunction. Moreover, its effects on visceral peristaltism and the mechanisms of action were studied. Rat isolated hearts were perfused inside a calorimeter, left intraventricular pressure and calorimetrical signals were recorded during ischemia/reperfusion. The NO-synthases and mKATP channels roles were evaluated by respectively blocking them with L-NAME and 5-HD before ischemia. After the experiment, western-blots for cellular pathways (p-AKT, p-PKCϵ, GSK3b and BCL-2) were done. In isolated intestinal, bladder and uterine rat tissues, contractile carbachol concentration-response curves (CCh-CRCs) were performed. The HPLC-DAD mainly showed prenylated flavonoids, beta acids and isoflavones. Hops-T increased contractile and energetic recoveries more significantly in the male rat hearts compared to females, due to beneficial NO production and mitochondrial mKATP channels activation. However, the p-AKT, p-PKCϵ, GSK3b or BCL-2 expressions were not affected after reperfusion. Hops-T inhibited CCh-CRCs in intestinal, bladder and uterine tissues through a non-competitive mechanism. Additionally, it showed a non-competitive antagonism of the Ca2+-CRCs in bladder tissues, similar to the effects observed with verapamil. In conclusion, oral Hops-T prevented cardiac mitochondrial and contractile ischemic dysfunction, and it was a good visceral antispasmodic medicine by interfering with Ca2+ influx. This is a significant finding since it pre-clinically supports the use of hops extract for prevention of visceral spasms and cardiac diseases associated with coronary insufficiency.

description: We select 50 main-belt asteroids with a diameter between 20 and 400 km for which we have (i) shape models derived by the lightcurve inversion method (LI) and (ii) resolved observations of good quality collected with the Keck II adaptive optics (AO) system in the near-infrared. We derive the size of these asteroids by minimizing the difference between the contours from deconvolved AO images and the projected silhouettes calculated from the shape model at the time of the AO observations. We compute the volume-equivalent diameters for 48 of these asteroids. For 15 of them, we remove the ambiguity of the pole orientation typical for shape models derived by the LI. We have found that our equivalent diameters are smaller by 3%, 7%, and 2% compared with the effective diameters derived from mid-IR photometric observations provided by IRAS, WISE and AKARI. For 40 asteroids with previously determined mass estimates, we compute their bulk densities and discuss the mass-density dependence with respect to taxonomic types.

description: This thesis investigates the association between air pollution and health in the UK and examines how this association varies by ethnicity and country of birth. It links high-resolution spatial data on air pollution to individual-level longitudinal data at different geographical scales. The thesis shows that higher concentrations of NO₂, SO₂, CO, PM10, and PM2.5 ambient air pollutants are associated with limiting long-term illness, poor self-reported health, lower ratings of mental well-being, and increased mortality rates and hospital admissions. Particulate matter is mainly associated with all-cause, respiratory, cardiovascular, infectious and cancer mortality and hospital admissions, while SO₂ is mostly related to mental/behavioural disorders/suicide mortality and respiratory hospital admissions. NO₂ is associated with all mortality and hospital admission causes. The analysis further shows that non-UK-born and ethnic minorities report poorer health with higher exposure to air pollution than UK-born and British-white individuals. Ethnic differences are not observed in the association between air pollution and mental well-being. This thesis supports the association between long-term exposure to air pollution and poor health and increased mortality and hospital admissions and shows that the effect of air pollution on health is exacerbated for ethnic minorities in the UK.

description: Differential entropy and log determinant of the covariance matrix of a multivariate Gaussian distribution have many applications in coding, communications, signal processing and statistical inference. In this paper we consider in the high dimensional setting optimal estimation of the differential entropy and the log-determinant of the covariance matrix. We first establish a central limit theorem for the log determinant of the sample covariance matrix in the high dimensional setting where the dimension $p(n)$ can grow with the sample size $n$. An estimator of the differential entropy and the log determinant is then considered. Optimal rate of convergence is obtained. It is shown that in the case $p(n)/n \rightarrow 0$ the estimator is asymptotically sharp minimax. The ultra-high dimensional setting where $p(n) > n$ is also discussed.

description: We report on the formation of ultralong-range Rydberg D-state molecules via photoassociation in an ultracold cloud of rubidium atoms. By applying a magnetic offset field on the order of 10 G and high resolution spectroscopy, we are able to resolve individual rovibrational molecular states. A full theory, using the Born-Oppenheimer approximation including s- and p-wave scattering, reproduces the measured binding energies. The calculated molecular wavefunctions show that in the experiment we can selectively excite stationary molecular states with an extraordinary degree of alignment or anti-alignment with respect to the magnetic field axis.

description: Quantum algorithms allow to outperform their classical counterparts in various tasks, most prominent example being Shor's algorithm for efficient prime factorization on a quantum computer. It is clear that one of the reasons for the speedup is the superposition principle of quantum mechanics, which allows a quantum processor to be in a superposition of different states at the same time. While such superposition can lead to entanglement across different qubits of the processors, there also exists quantum algorithms which outperform classical ones using superpositions of individual qubits without entangling them. As an example, the Bernstein-Vazirani algorithm allows one to determine a bit string encoded into an oracle. While the classical version of the algorithm requires multiple calls of the oracle to learn the bit string, a single query of the oracle is enough in the quantum case. In this Letter, we analyze in detail the quantum resources in the Bernstein-Vazirani algorithm. For this, we introduce and study its probabilistic version, where the goal is to guess the bit string after a single call of the oracle. We show that in the absence of entanglement, the performance of the algorithm is directly related to the amount of quantum coherence in the initial state. We further demonstrate that a large amount of entanglement in the initial state prevents the algorithm from achieving optimal performance. We also apply our methods to quantum computation with mixed states, proving that pseudopure states achieve optimal performance for a given purity in the Bernstein-Vazirani algorithm. We further investigate quantum resources in the one clean qubit model, showing that the model can exhibit speedup over any known classical algorithm even with arbitrary little amount of multipartite entanglement, general quantum correlations, and coherence.

description: Endophytic fungi from Aglaia argentea have indicated the prospective to produce secondary metabolites with unique activities, making them promising candidates for anticancer drug development. This study aimed to investigate the secondary metabolites produced by Lasiodiplodia theobromae BPPCA144, isolated from A. argentea. L. theobromae BPPCA144 was found to produce seven compounds: 2-phenylethanol (1), tyrosol (2), 2-(4-hydroxyphenyl)acetic acid (3), (-)-mellein (4), colletopeptide B (5), botryorhodine A (6), and (4R*,6R*)-4-hydroxy-6-n-propyl-1-oxacyclohexan-2-one (7). These compounds were isolated using vacuum liquid and radial chromatography, and their chemical structures were elucidated through 1D-NMR, 2D-NMR analysis, compared with previously reported spectral data. Notably, compounds (5) and (7) were identified as original from L. theobromae. Among the tested compounds, compound (2) exhibited the strongest activity against MCF-7 breast cancer cells. However, compounds (1, 3, 5 and 7) showed insufficient activity against CV-1 cell lines (normal kidney fibroblast cells).

description: We analyze general F-theory compactifications with U(1) x U(1) x U(1) Abelian gauge symmetry by constructing the general elliptically fibered Calabi-Yau manifolds with a rank three Mordell-Weil group of rational sections. The general elliptic fiber is shown to be a complete intersection of two non-generic quadrics in P^3 and resolved elliptic fibrations are obtained by embedding the fiber as the generic Calabi-Yau complete intersection into Bl_3 P^3, the blow-up of P^3 at three points. For a fixed base B, there are finitely many Calabi-Yau elliptic fibrations. Thus, F-theory compactifications on these Calabi-Yau manifolds are shown to be labeled by integral points in reflexive polytopes constructed from the nef-partition of Bl_3 P^3. We determine all 14 massless matter representations to six and four dimensions by an explicit study of the codimension two singularities of the elliptic fibration. We obtain three matter representations charged under all three U(1)-factors, most notably a tri-fundamental representation. The existence of these representations, which are not present in generic perturbative Type II compactifications, signifies an intriguing universal structure of codimension two singularities of the elliptic fibrations with higher rank Mordell-Weil groups. We also compute explicitly the corresponding 14 multiplicities of massless hypermultiplets of a six-dimensional F-theory compactification for a general base B.

description: Eelgrass, Zostera marina L., is vital to marine ecosystems, providing habitat, filtering pollutants, improving water quality, and serving as a source of bioactive compounds for pharmaceuticals. This study aimed to isolate and identify phenolic compounds from Z. marina, biotransform the main metabolite, rosmarinic acid (RA), and evaluate the anti-tyrosinase activity of these compounds. Various chromatographic techniques were employed to isolate compounds from Z. marina (1-4). Compound 1, exhibiting broad pharmaceutical activity, was biotransformed by Deinococcus geothermalis amylosucrase (DgAS) into two new glycosylated products (5-6). The isolated and biotransformed compounds were tested for anti-tyrosinase activity using a mushroom tyrosinase assay. Molecular docking and quantum chemical calculations were conducted to clarify the binding mode and reactivity of the compounds. The isolated compounds were identified via NMR and HR-MS as rosmarinic acid (RA) 1, methyl rosmarinate 2, methyl isorinate 3, and pinoresinol 4′-O-β-D-glucopyranoside 4. This is the first report of isolating and identifying compounds (2-4) from the Zosteraceae family. The glycosylated compounds were identified as rosmarinic acid 4-O-α-D-glucopyranoside 5 and rosmarinic acid 3′-O-α-D-glucopyranoside 6. Among all compounds, (4-6) showed significant tyrosinase inhibition, with rates of 55.5%, 22.3%, and 30.8%, respectively, compared to arbutin. The two glycosylated products exhibited better anti-tyrosinase activity than 1. In silico results aligned with in vitro findings. This study highlights Z. marina’s potential as a source of polyphenolic compounds with significant anti-aging activity, emphasizing the discovery of new anti-aging ingredients to enhance quality of life.

description: The combined action of a DC bias and a microwave drive on the transport characteristic of a superconductor-quantum dot-superconductor junction is investigated. To cope with time dependent non-equilibrium effects and interactions in the quantum dot, we develop a general formalism for the dynamics of the density operator based on a particle conserving approach to superconductivity. Without invoking a broken U (1) symmetry, we identify a dynamical phase connected to the coherent transfer of Cooper pairs across the junction. In the weak coupling limit, we show that besides quasiparticle transport, proximity induced superconducting correlations manifest in anomalous pair tunneling involving the transfer of a Cooper pair. The resulting generalized master equation in presence of the microwave drive showcases the characteristic bichromatic response due to the combination of the AC Josephson effect and an AC voltage. Analytical expressions for all harmonics in the driving frequency of both the current and the reduced dot operator are given for arbitrary driving strength. For the net DC current the resulting photon assisted processes give rise to rich current-voltage characteristics. In addition to photon assisted subgap transport we find regions of total current inversion in the stability diagram. There, the junction acts as a pump with the net DC current flowing against the applied DC bias. The first harmonic of the current, being closely related to the nonlinear dynamic susceptibility of the junction, is discussed at finite applied DC bias.
Characterizing the quiescent X-ray variability of the black hole low mass x-ray binary V404 Cyg

description: We conducted the first long-term (75 days) X-ray monitoring of the black hole low mass X-ray binary V404 Cyg, with the goal of understanding and characterizing its variability during quiescence. The X-ray light curve of V404 shows several flares on timescales of hours with a count rate change of a factor of about 5-8. The root mean square variability is Fvar = 57.0(3.2) percent. The first order structure function is consistent with both a power spectrum of index -1 (flicker noise), or with a power spectrum of index 0 (white noise), implying that the light curve is variable on timescales from days to months. The X-ray spectrum is well fitted by a power law with spectral index Γ = 2.10 - 2.35, and we found that the spectral shape remains roughly constant as the flux changes. A constant spectral shape with respect to a change in the X-ray flux may favour a scenario in which the X-ray emission is dominated by synchrotron radiation produced in a jet.

description: Curcumin is well known for its diverse health benefits based on the traditional and current scientific evidence. The aim of the present study was to evaluate the safety of Maxicuma® made by using proprietary LIMAN technology that involves encapsulation of 40% curcuminoids with lipid matrix. The safety profile was studied with single dose and repeated dose oral administration of Maxicuma® in both rodents and non-rodents. The toxicity study was conducted at a range of 0.5 to 10 gm curcumin equivalent to human dose per day. None of the tested doses in any of the species produced treatment related clinical signs of toxicity with respect to haematology and blood chemistry parameters and mortality. Moreover gross and histopathological findings did not show any remarkable and treatment related changes. The treated animals exhibited normal weight gain and comparable feed intake. Based on the obtained results Maxicuma® up to 220 mg/kg oral dose could be considered as safe, tolerated and no observed adverse effect level (NOAEL) dose in rabbits.

description: In this paper, we have studied nonstationary radiative spherically symmetric spacetime, in general covariant theory ($U(1)$ extension) of Hořava-Lifshitz gravity without the projectability condition and in the infrared limit. The Newtonian prepotential $φ$ was assumed null. We have shown that there is not the analogue of the Vaidya's solution in the Hořava-Lifshitz Theory (HLT), as we know in the General Relativity Theory (GRT). Therefore, we conclude that the gauge field $A$ should interact with the null radiation field of the Vaidya's spacetime in the HLT.

description: We present spectra and lightcurves of SNLS 06D4eu and SNLS 07D2bv, two hydrogen-free superluminous supernovae discovered by the Supernova Legacy Survey. At z = 1.588, SNLS 06D4eu is the highest redshift superluminous SN with a spectrum, at M_U = -22.7 is one of the most luminous SNe ever observed, and gives a rare glimpse into the restframe ultraviolet where these supernovae put out their peak energy. SNLS 07D2bv does not have a host galaxy redshift, but based on the supernova spectrum, we estimate it to be at z ~ 1.5. Both supernovae have similar observer-frame griz lightcurves, which map to restframe lightcurves in the U-band and UV, rising in ~ 20 restframe days or longer, and declining over a similar timescale. The lightcurves peak in the shortest wavelengths first, consistent with an expanding blackbody starting near 15,000 K and steadily declining in temperature. We compare the spectra to theoretical models, and identify lines of C II, C III, Fe III, and Mg II in the spectrum of SNLS 06D4eu and SCP 06F6, and find that they are consistent with an expanding explosion of only a few solar masses of carbon, oxygen, and other trace metals. Thus the progenitors appear to be related to those suspected for SNe Ic. A high kinetic energy, 10^52 ergs, is also favored. Normal mechanisms of powering core- collapse or thermonuclear supernovae do not seem to work for these supernovae. We consider models powered by 56Ni decay and interaction with circumstellar material, but find that the creation and spin-down of a magnetar with a period of 2ms, magnetic field of 2 x 10^14 Gauss, and a 3 solar mass progenitor provides the best fit to the data.

description: Acute pancreatitis develops as a local inflammatory condition of the pancreas due to a wide range of factors including overdose of alcohol or drugs, gall stones, etc. At present, medications based on herbal formulations have gained importance due to their better safety profile. Current study assessed the pharmacological effects of Pancogrit, an herbal medicine, in caerulein and TNF-α-induced in vitro pancreatitis models. A comprehensive evaluation of phytometabolites present in Pancogrit was conducted and 85 phytometabolites were identified through UPLC-QTOF-MS and UPLC-UV. The bioactivity and mode of action of Pancogrit were assessed in caerulein-induced AR42J (rat pancreatic acinar) cells, TNF-α-induced PANC-1 (human pancreatic duct) cells, and NF-κB reporter cells. Pancogrit was found to decrease the elevated amylase and lipase activity in caerulein-induced AR42J cells. It ameliorated the increased ROS levels, IL-6, IL-8 release and NF-κB activity in TNF-α-induced PANC-1 and NF-κB reporter cells. Pancogrit also downregulated IL-6, IL-1β, ICAM-1, and STAT3 gene expression in PANC-1 cells. Moreover, Pancogrit inhibited the protein expression levels of phosphorylated STAT3, phosphorylated and total JAK2 in TNF-α-induced PANC-1 cells. Taken together, Pancogrit is a clinically relevant therapeutic agent for mitigation of pancreatitis.

description: One of the most striking features of the strong interactions between Rydberg atoms is the dipole blockade effect, which allows only a single excitation to the Rydberg state within the volume of the blockade sphere. Here we present a method that spatially visualizes this phenomenon in an inhomogeneous gas of ultra-cold rubidium atoms. In our experiment we scan the position of one of the excitation lasers across the cold cloud and determine the number of Rydberg excitations detected as a function of position. Comparing this distribution to the one obtained for the number of ions created by a two-photon ionization process via the intermediate 5P level, we demonstrate that the blockade effect modifies the width of the Rydberg excitation profile. Furthermore, we study the dynamics of the Rydberg excitation and find that the timescale for the excitation depends on the atomic density at the beam position.
