description: Millisecond pulsars with strong magnetic fields may be formed through several processes, e.g. accretion-induced collapse of magnetized white dwarfs, merger of two neutron stars. During the birth of such a pulsar, an initial fireball available for a gamma-ray burst (GRB) may occur. We here study evolution of a postburst relativistic fireball with energy injection from the pulsar through magnetic dipole radiation, and find that the magnitude of the optical afterglow from this fireball first decreases with time, subsequently flattens, and finally declines again. This may provide a natural explanation for the behavior of the lightcurve of the afterglow of GRB970228 if this burst resulted from the birth of a strongly magnetic millisecond pulsar.

Disk galaxies at Z=0 and at High Redshift: an explanation of the observed evolution of damped Ly-alpha systems

description: The analysis of disk formation is based on the White & Rees (1978) picture, in which disk galaxies form by continuous cooling and accretion of gas within a merging hierarchy of dark matter halos. A simple Kennicutt law of star formation for disks, based on a single- fluid gravitational instability model is introduced. Since the gas supply in the disk is regulated by infall from the surrounding halo, the gas is always maintained at a critical threshold surface density. Chemical enrichment of the disks occurs when the surrounding hot halo gas is enriched with heavy elements ejected during surpernova explosions. This gas then cools onto the disk producing a new generation of metal-rich stars. I first show that models of this type can reproduce many of the observed properties of a typical spiral galaxy like the Milky Way, including its gas and stellar surface density profiles and the observed relationship between the ages and metallicities of solar neighbourhood stars. I then use the models to make inferences about the properties of disk galaxies at high redshift. The total neutral hydrogen density Omega(HI) increases at higher z. The predicted increase is mild, but is roughly consistent with the latest derivation of Omega(HI) as a function of z by Storrie-Lombardi & MacMahon (1995). The models are also able to account for some of the other trends other trends seen in the high-redshift data, including the increase in the number of high column-density systems at high redshift, as well as the metallicity distribution of damped Lyman-alpha systems at redshifts 2-3.

description: It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias? We consider the possibility that bursts of a given bolometric luminosity occur with a hardness distribution $p(H)d \log H \propto H^γd \log H$. We model the detection efficiency of BATSE as a function of $H$ and calculate the expected distribution of $H$ in the observed sample for various values of $γ$. We show that because the detection efficiency of BATSE falls steeply with increasing $H$, the paucity of hard bursts need not be real. We find that the observed sample is consistent with a distribution above $H = 100$ keV with $γ\approx 0$ or even $γ=0.5$. Thus, a large population of unobserved hard gamma-ray bursts may exist. It is important to extend the present analysis to a larger sample of BATSE bursts and to include the OSSE and COMPTEL limits. If the full sample is consistent with $γ \sgreat\ 0$, then it would be interesting to look for MeV bursts in the future.

description: This study explores the potential of neuromorphic Event-Based Vision (EBV) cameras for data-efficient representation of low-order model coordinates in turbulent flows. Unlike conventional imaging systems, EBV cameras asynchronously capture changes in temporal contrast at each pixel, delivering high-frequency output with reduced data bandwidth and enhanced sensitivity, particularly in low-light conditions. Pulsed Event-Based Imaging Velocimetry (EBIV) is assessed against traditional Particle Image Velocimetry (PIV) through two synchronized experiments: a submerged water jet and airflow around a square rib in a channel. The assessment includes a detailed comparison of flow statistics and spectral content, alongside an evaluation of reduced-order modeling capabilities using Proper Orthogonal Decomposition (POD). The event stream from the EBV camera is converted into pseudo-snapshots, from which velocity fields are computed using standard PIV processing techniques. These fields are then compared after interpolation onto a common grid. Modal analysis demonstrates that EBIV can successfully identify dominant flow structures, along with their energy and dynamics, accurately discerning singular values, spatial modes, and temporal modes. While noise contamination primarily affects higher modes - less critical for flow control applications - overall performance remains robust. Additionally, comparisons of Low-Order Reconstruction (LOR) validate EBIV's capability to provide reliable reduced-order models of turbulent flows, essential for flow control purposes. These findings position EBV sensors as a promising technology for real-time, imaging-based closed-loop flow control systems.

Sensitivity analysis for the anomalous $tqγ$ couplings via $ γq {\rightarrow} t γ$ subprocess in photon-proton collisions at the FCC-$μ$p

description: In this study, we investigate anomalous flavour-changing neutral current (FCNC) interactions related to the top quark, particularly the $t\rightarrow qγ$ transition, within the Standard Model Effective Field Theory (SMEFT) framework. These rare processes are largely suppressed in the Standard Model (SM) and are strong indicators for new physics scenarios beyond the SM. In our study, we have analyzed the cross sections of the $ γq {\rightarrow} t γ$ subprocess for two different center-of-mass energies, 17.3 TeV and 24.5 TeV, at the Future Circular Collider (FCC-$μ$p) collider. Our results derived from simulations show that the branching ratios for these processes can be reduced to the order of $10^{-5} $. These values provide significantly tighter limits than the current experimental limits. In light of these findings, it can be stated that the FCC-$μ$p collider offers significant potential for discovering new physics which represents a sensitivity improvement over the current experimental limits from CMS, enhancing sensitivity by approximately 30\%.Moreover, it has been demonstrated that higher centre-of-mass energies and integrated luminosity values significantly enhance the discovery potential of these rare processes. Accordingly, the results indicate that-energy colliders such as FCC-$μ$p are of critical importance in the search for new physics and in the study of the role of the top quark in the context of flavour physics. As a result, by providing a comprehensive theoretical analysis, this study contributes to the importance of FCNC processes in the search for new physics beyond the Standard Model and will shed light on future experimental and phenomenological studies.

description: Synthesis and characterization of (E)-4-((5-bromo-2-(λ1-oxidanyl)benzylidene)amino)-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzenesulfonamide (1), its substituted phthalonitrile derivative (2), and its tetra substituted zinc(II) phthalocyanine complex (3) were performed. Compounds 1, 2, and 3 were characterized by methods such as elemental analyses, FT-IR, 1H-NMR, 13C-NMR (except for 3), and MALDI-TOF mass spectra. The photophysical and photochemical properties of this substituted zinc(II) phthalocyanine complex aimed to be used as a photosensitizer were investigated in DMSO solution for determination of their photosensitizing abilities in photocatalytic applications such as photodynamic therapy (PDT). The influence of the substituent as a bioactive compound on the phthalocyanine skeleton on spectroscopic, photophysical, and photochemical properties were also determined and compared with unsubstituted zinc(II) phthalocyanine and some zinc(II) phthalocyanines containing different substituents previously studied. According to photophysical and photochemical investigations, 3 has potential as a photosensitizer for PDT.

description: Projected entangled pair states (PEPS) are very useful in the description of strongly correlated systems, partly because they allow encoding symmetries, either global or local (gauge), naturally. In recent years, PEPS with local symmetries have increasingly been used in the study of non-perturbative regimes of lattice gauge theories, most prominently as a way to construct variational ansatz states depending only on a small number of parameters and yet capturing the relevant physical properties. For the case of one-dimensional PEPS (Matrix Product States - MPS) a bidirectional connection was established between the internal structure of the tensor network, i.e. the mathematical properties of the constituent tensors, and the symmetry. In higher dimensions this has only been done for global symmetries, where in the local (gauge) case it is known only how to construct gauge-invariant states, but not what the symmetry implies on the internal structure of the PEPS. In the present work we complete this missing piece and study the internal structure of projected entangled pair states with a gauge symmetry. The PEPS we consider consist of matter and gauge field tensors placed on the vertices and edges, respectively, of arbitrary graphs.

description: We associate to every quandle $X$ and an associative ring with unity $\mathbf{k}$, a nonassociative ring $\mathbf{k}[X]$ following [3]. The basic properties of such rings are investigated. In particular, under the assumption that the inner automorphism group $Inn(X)$ acts orbit $2$-transitively on $X$, a complete description of right (or left) ideals is provided. The complete description of right ideals for the dihedral quandles $R_n$ is given. It is also shown that if for two quandles $X$ and $Y$ the inner automorphism groups act $2$-transitively and $\mathbf{k}[X]$ is isomorphic to $\mathbf{k}[Y]$, then the quandles are of the same partition type. However, we provide examples when the quandle rings $\mathbf{k}[X]$ and $\mathbf{k}[Y]$ are isomorphic, but the quandles $X$ and $Y$ are not isomorphic. These examples answer some open problems in [3].

A Simultaneous Spectral Invariant Analysis of the GRB Count Distribution and Time Dilation

Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: The analysis of the BATSE's count distribution within cosmological models suffers from observational uncertainties due to the variability of the bursts' spectra: when BATSE observes bursts from different redshifts at a fixed energy band it detects photons from different energy bands at the source. This adds a spectral dependence to the count distribution $N(C)$. Similarly variation of the duration as a function of energy at the source complicates the time dilation analysis. We describe here a new statistical formalism that performs the required ``blue shifting" of the count number and the burst duration in a statistical manner. This formalism allows us to perform a combined best fit (maximal likelihood) to the count distribution, $N(C)$, and the duration distribution simultaneously. The outcome of this analysis is a single best fit value for the redshift of the observed bursts.

description: Soybean damping-off caused by Pythium spp. is frequently associated with the occurrence of cold weather fronts soon after spring planting. In this study, we evaluated the efficacy of a commercial seed treatment with metalaxyl and ethaboxam on emergence during various simulated cold stress conditions. A growth chamber experiment utilized a five-way factorial design with two cold stress temperatures (4ºC and 10ºC), two cold stress timings (initiated 24 and 96 h after planting), three durations of cold stress (24, 48 and 96 h), and two levels of seed treatment (INTEGO SUITETM and untreated). Cups planted with soybean seeds IA 2094 were inoculated with P. sylvaticum or not inoculated. Cups were incubated at 18ºC and evaluated 21 days after planting. Seedling emergence was reduced when the pathogen was present compared with the non-inoculated controls. In untreated seed, cold stress duration reduced seedling emergence, but no differences in emergence were detected in response to either initiation of cold stress or cold stress temperature. The seed treatment improved seedling emergence, reduced root rot severity and increased shoot weight. There was no significant effect of seed treatment on root weight. Data from this study confirm that cold stress soon after planting can increase the risk of reduced crop stands in Iowa and suggest that seed treatment with metalaxyl and ethaboxam protects seedlings when cold conditions are expected soon after planting.
An analytic model for the spatial clustering of dark matter haloes

description: We develop a simple analytic model for the gravitational clustering of dark matter haloes to understand how their spatial distribution is biased relative to that of the mass. The statistical distribution of dark haloes within the initial density field (assumed Gaussian) is determined by an extension of the Press-Schechter formalism. Modifications of this distribution caused by gravitationally induced motions are treated using a spherical collapse approximation. We test this model against results from a variety of N-body simulations, and find that it gives an accurate description of a bias function. This bias function is sufficient to calculate the cross-correlation between dark haloes and mass, and again we find excellent agreement between simulation results and analytic predictions. Because haloes are spatially exclusive, the variance in the count of objects within spheres of fixed radius and overdensity is significantly smaller than the Poisson value. This seriously complicates any analytic calculation of the autocorrelation function of dark halos. Our simulation results show that this autocorrelation function is proportional to that of the mass over a wide range in $R$, even including scales where both functions are significantly greater than unity. The constant of proportionality is very close to that predicted on large scales by the analytic model. This result permits an entirely analytic estimate of the autocorrelation function of dark haloes. We use our model to study how the distribution of galaxies may be biased with respect to that of the mass. In conjunction with other data these techniques should make it possible to measure the amplitude of cosmic mass fluctuations and the density of the Universe.

description: With the photometric data from the SDSS survey, the spectroscopic data from the SDSS/SEGUE and the LAMOST surveys, and the astrometric data from the Gaia DR2, we have identified 71 highly-probable member stars of the GD-1 cold stellar stream spread along almost its entire length (i.e. from 126 to 203 degree in Right Ascension). With the accurate spectroscopic (i.e. metallicity and line-of-sight velocity) and astrometric (i.e. proper motions) information, the position-velocity diagrams, i.e. $ϕ_{1}$-$μ_α$, $ϕ_{1}$-$μ_δ$ and $ϕ_{1}$-${v_{\rm gsr}}$, of the GD-1 stream are well mapped. The stream has an average metallicity [Fe/H] $= -1.95 \pm 0.23$. The rich information of member stars of the stream now available allow one not only to model its origin, but also to place strong constraints on the mass distribution and the gravitational potential of the Milky Way.

The roles of bacterial virulence mechanisms including intracellular persistence in determining outcome of infection by invasive nontyphoidal Salmonella
Creators: name: Rycroft, Julian Anthony
Publisher: name: Imperial College London
Year: 2016

description: While typhoidal serovars of Salmonella are human-restricted and cause invasive disease, nontyphoidal serovars infect a range of mammalian hosts, causing enterocolitis or systemically disseminated “invasive” disease. Invasive nontyphoidal salmonellosis is a major neglected tropical disease. In sub-Saharan Africa emergent clades of genetically distinct invasive strains are amongst the most common cause of bacteraemia. Prevalence, mortality and recurrence are all high. There is growing evidence that recurrence is attributable to resuscitation of non-growing intracellular persister Salmonella, the induction of which depends on a repertoire of class II toxin-antitoxin modules. A selection of invasive strains of S. Typhimurium and S. Enteritidis were experimentally compared to non-invasive reference strains with the aim of identifying pathogen factors associated with invasive disease. Invasive strains were less efficient at infecting human epithelial cells cultured in vitro, reflecting the loss of genes associated with an enteric lifestyle from these strains. Invasive strains were also less pro-inflammatory than reference strains, and induced less IL-1β secretion from human macrophage-like cells infected in vitro; although there was no evidence for superior survival of invasive strains within mammalian macrophages. All invasive strains were able to undergo the phenotypic switch to the persister state following internalisation by human macrophages, especially macrophages polarised to the pro-inflammatory, replication-restricting M1 phenotype. Investigating differences in the TA repertoire between serovars facilitated the characterisation of two members of a novel family of three Salmonella class II toxins. These two toxins induced the persister state by inhibiting translation, which was dependent on the transfer of an acetyl moiety to a negatively charged substrate. A genomic screen revealed a potential role for multiple genes in persister resuscitation and added evidence to the assertion that the negatively charged substrate of these toxins, as is already known to be the target of third member TacT, is also aminoacylated-tRNA.

description: When we search online for content, we are constantly exposed to rankings. For example, web search results are presented as a ranking, and online bookstores often show us lists of best-selling books. While popularity-based ranking algorithms (like Google's PageRank) have been extensively studied in previous works, we still lack a clear understanding of their potential systemic consequences. In this work, we fill this gap by introducing a new model of network growth that allows us to compare the properties of the networks generated under the influence of different ranking algorithms. We show that by correcting for the omnipresent age bias of popularity-based ranking algorithms, the resulting networks exhibit a significantly larger agreement between the nodes' inherent quality and their long-term popularity, and a less concentrated popularity distribution. To further promote popularity diversity, we introduce and validate a perturbation of the original rankings where a small number of randomly-selected nodes are promoted to the top of the ranking. Our findings move the first steps toward a model-based understanding of the long-term impact of popularity-based ranking algorithms, and could be used as an informative tool for the design of improved information filtering tools.

description: A kinetic model for the dynamics of collisionless spin neutral particles in a spacetime with torsion is proposed. The fundamental matter field is the kinetic density $f(x,u,s)$ of particles with four-velocity $u$ and four-spin $s$. The stress-energy tensor and the spin current of the particles distribution are defined as suitable integral moments of $f$ in the $(u,s)$ variables. By requiring compatibility with the contracted Bianchi identity in Einstein-Cartan theory, we derive a transport equation on the kinetic density $f$ that generalizes the well-known Vlasov equation for spinless particles. The total number of particles in the new model is not conserved. To restore this important property we assume the existence in spacetime of a second species of particles with the same mass and spin magnitude. The Vlasov equation on the kinetic density $\overline{f}$ of the new particles is derived by requiring that the sum of total numbers of particles of the two species should be conserved.

Modelling self-potentials as a predictor of seawater intrusion in coastal groundwater boreholes
Creators: name: Graham, Malcolm
Publisher: name: Imperial College London
Year: 2018

description: Seawater intrusion is pervasive on every inhabited continent, although existing monitoring techniques typically fail to predict the timing of its occurrence in groundwater boreholes. Recent monitoring of a coastal groundwater observation borehole suggests that a nearby saline front can affect self-potential (SP) signals and could be used to predict saline intrusion. The borehole displays a persistent SP gradient, which is absent in boreholes further inland. This gradient reduces several days before saline breakthrough, constituting a possible precursor to intrusion, and fluctuates at the same frequency as oceanic tides. The magnitude of the oscillations reduces prior to breakthrough. A numerical model of the surrounding Chalk aquifer explains the SP gradient and precursor for the first time. The gradient requires spatial variation in the exclusion-efficiency of the aquifer, a parameter that, in the context of seawater intrusion in the Chalk, describes the extent to which anions are excluded from the pore space and which has been linked previously to rocks with narrow pore throats. The modelled precursor is a response to seawater moving through fractures with a change in exclusion-efficiency across them. The fractures driving the precursor may either intersect the borehole or lie immediately beneath it. However, the observed reduction in SP oscillations can only be replicated in the latter scenario. The model relies on relatively high values of exclusion-efficiency in marl horizons, a parameter that had not been measured previously in this lithology. The results of marl testing carried out as part of this project closely agree with the simulated values and provide greater confidence in the model. These SP phenomena were observed in a single coastal groundwater observation borehole. To understand fully the applicability of SP monitoring and modelling for predicting seawater intrusion, it should now be applied to boreholes in different aquifer types, including operating abstraction boreholes.

description: A low-dispersion Keck I spectrum of SN 1980K taken in August 1995 (t = 14.8 yr after explosion) and a November 1997 MDM spectrum (t = 17.0 yr) show broad 5500 km s^{-1} emission lines of Hα, [O I] 6300,6364 A, and [O II] 7319,7330 A. Weaker but similarly broad lines detected include [Fe II] 7155 A, [S II] 4068,4072 A, and a blend of [Fe II] lines at 5050--5400 A. The presence of strong [S II] 4068,4072 A emission but a lack of [S II] 6716,6731 A emission suggests electron densities of 10^{5-6} cm^{-3}. From the 1997 spectra, we estimate an Hαflux of 1.3 \pm 0.2 \times 10^{-15} erg cm^{-2} s^{-1} indicating a 25% decline from 1987--1992 levels during the period 1994 to 1997, possibly related to a reported decrease in its nonthermal radio emission.

description: The debate between self-interpretable models and post-hoc explanations for black-box models is central to Explainable AI (XAI). Self-interpretable models, such as concept-based networks, offer insights by connecting decisions to human-understandable concepts but often struggle with performance and scalability. Conversely, post-hoc methods like Shapley values, while theoretically robust, are computationally expensive and resource-intensive. To bridge the gap between these two lines of research, we propose a novel method that combines their strengths, providing theoretically guaranteed self-interpretability for black-box models without compromising prediction accuracy. Specifically, we introduce a parameter-efficient pipeline, AutoGnothi, which integrates a small side network into the black-box model, allowing it to generate Shapley value explanations without changing the original network parameters. This side-tuning approach significantly reduces memory, training, and inference costs, outperforming traditional parameter-efficient methods, where full fine-tuning serves as the optimal baseline. AutoGnothi enables the black-box model to predict and explain its predictions with minimal overhead. Extensive experiments show that AutoGnothi offers accurate explanations for both vision and language tasks, delivering superior computational efficiency with comparable interpretability.

description: Synthesis and characterization of (E)-4-((5-bromo-2-(λ1-oxidanyl)benzylidene)amino)-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzenesulfonamide (1), its substituted phthalonitrile derivative (2) and its tetra substituted zinc(II) phthalocyanine complex (3) were performed. Compounds 1, 2 and 3 were characterized by methods such as elemental analyses, FT-IR, 1H-NMR, 13C-NMR (except for 3) and MALDI-TOF mass spectra. The photophysical and photochemical properties of this substituted zinc(II) phthalocyanine complex aimed to be used as a photosensitizer were investigated in DMSO solution for determination of their photosensitizing abilities in photocatalytic applications such as photodynamic therapy. The influence of the substituent as a bioactive compound on the phthalocyanine skeleton on spectroscopic, photophysical and photochemical properties were also determined and compared with unsubstituted zinc(II) phthalocyanine and some zinc(II) phthalocyanines containing different substituents previously studied. According to photophysical and photochemical investigations, 3 has potential as a photosensitizer for photodynamic therapy.

The parabolic exotic t-structure

subject: FOS: Mathematics

description: Let G be a connected reductive algebraic group over an algebraically closed field k, with simply connected derived subgroup. The exotic t-structure on the cotangent bundle of its flag variety T^*(G/B), originally introduced by Bezrukavnikov, has been a key tool for a number of major results in geometric representation theory, including the proof of the graded Finkelberg-Mirkovic conjecture. In this paper, we study (under mild technical assumptions) an analogous t-structure on the cotangent bundle of a partial flag variety T^*(G/P). As an application, we prove a parabolic analogue of the Arkhipov-Bezrukavnikov-Ginzburg equivalence. When the characteristic of k is larger than the Coxeter number, we deduce an analogue of the graded Finkelberg-Mirkovic conjecture for some singular blocks.
Damping-off caused by Pythium sylvaticum on soybeans subjected to periods of cold stress is reduced by seed treatments

description: Soybean damping-off caused by Pythium spp. is frequently associated with the occurrence of cold weather fronts soon after spring planting. In this study, we evaluated the efficacy of a commercial seed treatment with metalaxyl and ethaboxam on emergence during various simulated cold stress conditions. A growth chamber experiment utilized a five-way factorial design with two cold stress temperatures (4ºC and 10ºC), two cold stress timings (initiated 24 and 96 hr after planting), three durations of cold stress (24, 48 and 96 hr), and two levels of seed treatment (INTEGO SUITETM and untreated). Cups planted with soybean seeds IA 2094 were inoculated with P. sylvaticum or not inoculated. Cups were incubated at 18ºC and evaluated 21 days after planting. Seedling emergence was reduced when the pathogen was present compared to the non-inoculated controls. In untreated seed, cold stress duration reduced seedling emergence, but no differences in emergence were detected in response to either initiation of cold stress or cold stress temperature. The seed treatment improved seedling emergence, reduced root rot severity, and increased shoot weight. There was no significant effect of seed treatment on root weight. Data from this study confirms that cold stress soon after planting can increase the risk of reduced crop stands in Iowa and suggest that seed treatment with metalaxyl and ethaboxam protects seedlings when cold conditions are expected soon after planting.
The effects of human disturbance on vascular epiphyte in the Brazilian Atlantic Forest
Creators: name: Parra Sánchez, Edicson
Publisher: name: Imperial College London

description: The high pressure that anthropogenic activities places on tropical forests are pushing species and communities to the brink of local, regional or global extinctions. However, the consequences of the loss of species and their ecosystem functions are not well known. My thesis addresses the causes and consequences of human disturbance on vascular epiphytes in the Brazilian Atlantic forest (BAF). I sampled understory and canopy, across a gradient of habitat loss, i.e. pastureland, human-modified forests (HMFs) and old-growth forest. I found that habitat loss has driven a net loss of 91% of species exclusive to old-growth, and 90% of individuals. I also found the edge effect to be a ubiquitous landscape process extending at least 500 m within forests habitats, leaving just 19.4% of the whole of the BAF suitable for forest-dependant epiphytes. However, whilst endemic species (habitat specialised species) are more prone to disappear as consequence of habitat loss, species with larger dispersal ranges and the ability to colonize different forest types flourish or endure the harsh conditions after disturbance. Consequently, HMFs have low functional richness and low functional redundancy, meaning low resilience, whereas old-growth forests exhibit high ecological resilience. Habitat transformation also leads to the loss of a large set of ecosystem functions related to pollination and water cycling across strata. Hence preserving large continuous forests are probably the only pragmatic conservation strategy for vascular epiphytes in highly human-modified landscapes. However, human-modified forests still provide limited ecosystem functions that may increase because of initiatives to improve habitat amount.
Stochastic models for valuation and risk management of credit-sensitive hybrid derivatives
Creators: name: Pede, Nicola
Publisher: name: Imperial College London
Year: 2018

description: We investigated different ways to model the dependence between the credit and other market risk components in hybrid derivatives. To do so, we used both structural and reduced–form frameworks for credit risk modelling. In particular, we applied results from Analytically Tractable First–Passage (AT1P) model — a model belonging to the family of structural approaches — to the pricing of Contingent Conversion bonds and a reduced– form approach to the pricing of quanto Credit Default Swaps (CDS). With respect to the former problem, we proposed a method to incorporate regulatory capital information into an AT1P–based model. With respect to the latter, we showed how to derive coupled two–dimensional PDE systems to price quanto CDSs in reduced form approaches. Furthermore, we investigated the impact of jumps to default on the FX/credit dependence structure, arguing that this is necessary mechanism to explain the observed quanto CDS spreads on Italian Republic during the Euro–debt cri- sis of 2011–2012. We proved that an invariance property of the FX rate with respect to replacing it with its reciprocal rate is satisfied by our proposed, jump–to–default / diffusion, model. Finally, we applied both approaches to Credit Valuation Adjustment (CVA) estimation, where we discussed the modelling–choice impact on the wrong–way risk estimation.
The measurements of matter density perturbations amplitude from cosmological data

description: We compare various physically different measurements of linear matter density perturbation amplitude, $sigma_8$, which are obtained from the observations of CMB anisotropy, galaxy cluster mass function, weak gravitation lensing, matter power spectrum and redshift space distortions. We show that $σ_8$ measurement from CMB gravitational lensing signal based on Planck CMB temperature anisotropy data at high multipoles, $\ell>1000$, contradict to all other measurements obtained both from remaining Planck CMB anisotropy data and from other cosmological data, at about $3.7σ$ significance level. Therefore, these data currently should not be combined with other data to constrain cosmological parameters. With the exception of Planck CMB temperature anisotropy data at high multipoles, all other measurements are in good agreement between each other and give the following measurements of linear density perturbation amplitude: $σ_8=0.792\pm0.006$, mean density of the Universe: $Ω_m=0.287\pm0.007$, and Hubble constant: $H_0 = 69.4\pm 0.6$~km~s$^{-1}$~Mpc$^{-1}$. Taking in account the data on baryon acoustic oscillations and (or) direct measurements of the Hubble constant, one can obtain different constraints on sum of neutrino mass and number of relativistic species.

description: The effective coupling of the Higgs boson to a gluon pair is one of the most important parameters to test the Standard Model and search for the new physics beyond. In this paper, we propose several new observables based on the jet energy profile to extract the effective coupling. The statistical uncertainties of the effective coupling extracted by using new observables are derived and estimated based on the simulation at the future $e^+e^-$ collider for $250$ GeV center-of-mass energy and 5 ab$^{-1}$ integrated luminosity. We found that the statistical uncertainties of effective coupling via the optimized observable can reach about $1.6\%$ in the channels of a $Z$ boson decaying to lepton pairs and is reduced by $52\%$ compared to the relevant uncertainties in the conventional approach. These new observables potentially can be helpful for the measurement of effective coupling at future $e^+e^-$ colliders.

description: One new indole diterpenoid, drechmerin I (1), was isolated from the fermentation broth of Drechmeria sp. isolated from the root of Panax notoginseng. Its structure was elucidated based on 1 D and 2 D nuclear magnetic resonance (NMR), high resolution electrospray ionization mass spectrum (HRESIMS), and electronic circular dichroism (ECD) spectroscopic analyses as well as TD DFT calculations of ECD spectra. Drechmerin I (1) was assayed for its antimicrobial activity against Candida albicans, Staphylococcus aureus, Bacillus cereus, B. subtillis, Pseudomonas aeruginosa, and Klebsiella pneumonia, respectively. Drechmerin I (1) showed antimicrobial activities against B. subtillis with an MIC value of 200 μg/mL. The interaction of S. aureus peptide deformylase with drechmerin I (1) was investigated by molecular docking.
