Type: “Hab. in regione mediâ montis Sipyli suprâ Magnesiam cl. Balansa”.
Holotypus: TURKEY: “Partie moyenne du Mont Sipyle, au-dessus Magnésie”, 10.VI.1854, Balansa 85 (G-BOIS [G00332614]; iso-: BM [BM000582564], E [E00386106, E00386108], FI [FI 005708], G [G00371657, G00371785], GOET [GOET002624], JE [JE00001299], K [K000642882], KW [KW000127957], LE [LE00012928], P [P00741495, P00741498], US [US00099984], W [W0050162, W0050163, W1889158145], WAG [WAG0004252]).
Notes. – As indicated above, Boissier in Flora Orientalis reduced the species to synonymy of I. tinctoria var. stenocarpa.
This taxon, the preceding, and following entries clearly belong to the highly variable I. tinctoria complex, which is the most widespread naturalized species in the genus and the only one cultivated extensively in the past for the blue dye woad (LEGGETT, 1944). It is still cultivated in SW Asia, through the central Asian republics of the former Soviet Union, into western and central China.
The lines separating its component infraspecific taxa can be tenuous and, therefore, DAVIS (1964) is followed in treating the extremes at the subspecific rather than the specific rank. In addition to Turkey, subsp. tomentella grows in Greece. However, in recognizing this entity at the species rank, TAN (2002: 127) erred in placing in its synonymy the earlier published I. corymbosa. Perhaps the ideal solution for the Greek representatives of this complex is to follow DAVIS (1964) in recognizing them at the subspecific rank.

description: In this work we investigate the ability of the cumulant expansion (CE) to capture one-particle spectral information in electron-phonon coupled systems at both zero and finite temperatures. In particular, we present a comprehensive study of the second- and fourth-order CE for the one-dimensional Holstein model as compared with numerically exact methods. We investigate both finite sized systems as well as the approach to the thermodynamic limit, drawing distinctions and connections between the behavior of systems in and away from the thermodynamic limit that enable a greater understanding of the ability of the CE to capture real-frequency information across the full range of wave vectors. We find that for zero electronic momentum, the spectral function is well described by the second-order CE at low and high temperatures. However, for non-zero electronic momenta, the CE is only accurate at high temperature. We analyze the fourth-order cumulant, and find that while it improves the description of the short-time dynamics encoded in the one-particle Green's function, it can introduce divergences in the time domain as well as unphysical negative spectral weight in the spectral function. When well-behaved, the fourth-order CE does provide notable accurate corrections to the second-order CE. Finally, we use our results to comment on the use of the CE as a tool for calculating transport behavior in the realistic ab initio modeling of materials.

description: Atypical teratoid rhabdoid tumours (ATRTs) are high-grade malignant paediatric brain tumours with a less than one-year survival rate after diagnosis. Current treatment for ATRT results in long-term side effects on ATRT patients. Here is an urgent need to discover targeted therapies that could be used to treat patients with ATRT. As part of the Hudson Monash Paediatric Precision Medicine Program, this project provides a framework for applying an integrative multi-omics approach in paediatric cancer precision medicine. This thesis demonstrates that ATRT cells preserved clinically relevant genetic architecture, and informed on novel therapeutic strategies for ATRT.

description: Hot Jupiters orbiting rapidly rotating stars on inclined orbits undergo tidally induced nodal precession measurable over several years of observations. The Hot Jupiters WASP-33 b and KELT-9 b are particularly interesting targets as they are among the hottest planets found to date, orbiting relatively massive stars. Here, we analyze archival and new data that span 11 and 5 years for WASP-33 b and KELT-9 b, respectively, in order to to model and improve upon their tidal precession parameters. Our work confirms the nodal precession for WASP-33 b and presents the first clear detection of the precession of KELT-9 b. We determine that WASP-33 and KELT-9 have gravitational quadrupole moments $(6.3^{+1.2}_{-0.8})\times10^{-5}$ and $(3.26^{+0.93}_{-0.80})\times10^{-4}$, respectively. We estimate the planets' precession periods to be $1460^{+170}_{-130}$ years and $890^{+200}_{-140}$ years, respectively, and that they will cease to transit their host stars around the years $2090^{+17}_{-10}$~CE and $2074^{+12}_{-10}$~CE, respectively. Additionally, we investigate both planets' tidal and orbital evolution, suggesting that a high-eccentricity tidal migration scenario is possible to produce both system architectures and that they will most likely not be engulfed by their hosts before the end of their main sequence lifetimes.

description: European Union’s Transport policy’s pivotal aim is to strengthen the existing Transport infrastructure, which is crucial to economic development. The improvement in the transport sector should provide efficient logistics of goods, better travel and commuting facilities, and accessibility of the European region.

This report, as part of the first phase of the Leveraging Big Data to Manage Transport Operations (LeMO) project, provides an introduction to big data in the transport sector. It identifies untapped opportunities and challenges and describes numerous data sources.

This report is a part of WP1 which is a cornerstone of the LeMO project. It aims to generate a shared understanding of current big data landscape in transport and identifies a holistic view on opportunities, challenges, and limitations.

The remainder of this report is structured as follows:

Chapter 2 explores the characteristic of big data and highlights the big data challenges in the transport sector. It covers six transportation modes (air, rail, road, urban, water and multi-modal) and two transportation sectors (passenger and freight).

Chapter 3 identifies several opportunities and challenges of big data in transportation, by using: several subject matter expert interviews, nineteen applied cases, and a literature review. It also indicates that the combination of different means and approaches will enhance the opportunities for successful big data services in the transport sector.

Chapter 4 offers an intensive survey of the various data sources, data producers, and service providers. In addition, cartography was modeled to visualize data flows intuitively. Cartography demonstrates where data originated from and where it is flowing to.

Chapter 5 summarizes all findings and provides a conclusion.

Type: “[Aucher-Eloy] N. 210, è Schedulâ collectionis meae in monte Tauro, ex eâ Musaei Parisiensis in Thessali â, circà Larissam ”.
Lectotypus (designated here): TURKEY: “in Mte. Tauro”, s.d., Aucher-Eloy 210 (G-BOIS [G00332615]; isolecto-: K [K000642883]). Syntypi: GREECE: “Inter Jugets Thessaliae. circa Larystam”, 1836, Aucher-Eloy s.n. (P [P00741424]); “ Thessalia ”, s.d., Aucher-Eloy s.n. (P [P00741425]).
Notes. – BOISSIER (1842b) based the species description on the unicate in his herbarium and on P00741424 that he annotated. Therefore, lectotypification is justified.
The label data in P00741426 is “Graecia, Cilicia, 1834 –1936, Aucher-Eloy 210 ”, and although the collection number is the same as that of the lectotype, the collection date and locality are quite different. To our knowledge, Cilicia is in southern Turkey, not Greece, and therefore, this specimen is not considered as part of the type collection.
The subspecies is distributed in the southwestern portions of Turkey, south central and western Greece, and Crimea. It was recognized by TAN (2002) as a synonym of Isatis tomentella (see previous entry), but it is more practical to treat it as independent taxon, as recognized here, by DAVIS (1965b), and BRASSIBASE (2019).

description: We present the discovery and validation of a temperate sub-Neptune around the nearby mid-M dwarf TIC 470381900 (TOI-1696), with a radius of $3.09 \pm 0.11 \,R_\oplus$ and an orbital period of $2.5 \,\rm{days}$, using a combination of TESS and follow-up observations using ground-based telescopes. Joint analysis of multi-band photometry from TESS, MuSCAT, MuSCAT3, Sinistro, and KeplerCam confirmed the transit signal to be achromatic as well as refined the orbital ephemeris. High-resolution imaging with Gemini/'Alopeke and high-resolution spectroscopy with the Subaru/IRD confirmed that there are no stellar companions or background sources to the star. The spectroscopic observations with IRD and IRTF/SpeX were used to determine the stellar parameters, and found the host star is an M4 dwarf with an effective temperature of $T_{eff} = 3185 \pm 76\,\rm{K}$ and a metallicity of [Fe/H] $=0.336 \pm 0.060 \,\rm{dex}$. The radial velocities measured from IRD set a $2$-$σ$ upper limit on the planetary mass to be $48.8 \,M_\oplus$. The large radius ratio ($R_p/R_\star \sim 0.1$) and the relatively bright NIR magnitude ($J=12.2 \,\rm{mag}$) make this planet an attractive target for further followup observations. TOI-1696b is one of the planets belonging to the Neptunian desert with the highest transmission spectroscopy metric discovered to date, making it an interesting candidate for atmospheric characterizations with JWST.

Die vorliegende Arbeit ist ein Versuch darzustellen, wie der derzeitige Bestand der Schutzgüter auf den Flächen eines ausgesuchten landwirtschaftlichen Grünlandbetriebes, welcher an einer Maßnahme aus diesem Programm teilnimmt, zusammengesetzt ist. Dazu wurden Vegetationsaufnahmen der entsprechenden Flächen durchgeführt und diese anschließend nach Pflanzengesellschaften ausgewertet. Um die Naturschutzaspekte darzustellen wurden die aufgenommenen Pflanzenarten mit den „Roten Listen der gefährdeten Pflanzen Österreichs“ sowie mit den „Signifikanten Arten“ des Anhangs II der FFH-Richtlinie verglichen. Ebenso wurde festgestellt, ob die auf den Flächen des Untersuchungsgebietes vorhandenen Pflanzengesellschaften auf der „Rote Liste der gefährdeter Biotoptypen Österreichs“ oder bei den Habitaten von gemeinschaftlicher Bedeutung des Anhangs I der FFH-Richtlinie aufscheinen.

description: The inverse Evershed flow (IEF) is a mass motion towards sunspots at chromospheric heights. We combined high-resolution observations of NOAA 12418 from the Dunn Solar Telescope and vector magnetic field measurements from the Helioseismic and Magnetic Imager (HMI) to determine the driver of the IEF. We derived chromospheric line-of-sight (LOS) velocities from spectra of H$α$ and Ca II IR. The HMI data were used in a non-force-free magnetic field extrapolation to track closed field lines near the sunspot in the active region. We determined their length and height, located their inner and outer foot points, and derived flow velocities along them. The magnetic field lines related to the IEF reach on average a height of 3 Mm over a length of 13 Mm. The inner (outer) foot points are located at 1.2 (1.9) sunspot radii. The average field strength difference $ΔB$ between inner and outer foot points is +400 G. The temperature difference $ΔT$ is anti-correlated with $ΔB$ with an average value of -100 K. The pressure difference $Δp$ is dominated by $ΔB$ and is primarily positive with a driving force towards the inner foot points of 1.7 kPa on average. The velocities predicted from $Δp$ reproduce the LOS velocities of 2-10 km s$^{-1}$ with a square-root dependence. We find that the IEF is driven along magnetic field lines connecting network elements with the outer penumbra by a gas pressure difference that results from a difference in field strength as predicted by the classical siphon flow scenario.

description: We present a class of dS/CFT correspondence between two-dimensional CFTs and three-dimensional de Sitter spaces. We argue that such a CFT includes an SU$(2)$ WZW model in the critical level limit $k\to -2$, which corresponds to the classical gravity limit. We can generalize this dS/CFT by considering the SU$(N)$ WZW model in the critical level limit $k\to -N$, dual to the higher-spin gravity on a three-dimensional de Sitter space. We confirm that under this proposed duality the classical partition function in the gravity side can be reproduced from CFT calculations. We also point out a duality relation known in higher-spin holography provides further evidence. Moreover, we analyze two-point functions and entanglement entropy in our dS/CFT correspondence. Possible spectrum and quantum corrections in the gravity theory are discussed.

description: We identify the rank $(q_{syk}+1)$ of the interaction of the two-dimensional ${\cal N}=(2,2)$ SYK model with the deformation parameter $λ$ in the Bergshoeff, de Wit and Vasiliev(in 1991)'s linear $W_{\infty}[λ]$ algebra via $λ=\frac{1}{2(q_{syk}+1)}$ by using a matrix generalization. At the vanishing $λ$ (or the infinity limit of $q_{syk}$), the ${\cal N}=2$ supersymmetric linear $W_{\infty}^{N,N}[λ=0]$ algebra contains the matrix version of known ${\cal N}=2$ $W_{\infty}$ algebra, as a subalgebra, by realizing that the $N$-chiral multiplets and the $N$-Fermi multiplets in the above SYK models play the role of the same number of $β\, γ$ and $b\, c$ ghost systems in the linear $W_{\infty}^{N,N}[λ=0]$ algebra. For the nonzero $λ$, we determine the complete ${\cal N}=2$ supersymmetric linear $W_{\infty}^{N,N}[λ]$ algebra where the structure constants are given by the linear combinations of two different generalized hypergeometric functions having the $λ$ dependence. The weight-$1, \frac{1}{2}$ currents occur in the right hand sides of this algebra and their structure constants have the $λ$ factors. We also describe the $λ=\frac{1}{4}$ (or $q_{syk}=1$) case in the truncated subalgebras by calculating the vanishing structure constants.

description: The paper introduces a Bayesian approach for estimating parameters of the Chris-Jerry distribution, focusing on the use of a conjugate prior, specifically the gamma prior. The Bayesian estimation method is developed with a various loss function, offering a robust framework for parameter estimation. symmetric loss function and Linex loss functions are commonly used in Bayesian statistics to balance the trade-off between bias and variance. The central idea is to derive the Bayes estimate of the distribution parameter by leveraging the properties of the conjugate gamma prior. Conjugate priors simplify the Bayesian analysis by ensuring that the posterior distribution belongs to the same family as the prior, facilitating analytical calculations. The proposed methodology is implemented and validated through numerical illustrations using. This involves applying the developed Bayesian estimation framework to real-world data or simulated scenarios, demonstrating its effectiveness and practical applicability. The numerical and simulation studies are done by using software.

description: A laser exhibits both controllable gain and loss and, under proper design conditions, is an ideal non-Hermitian system allowing the direct observation and engineering of spectral singularities such as exceptional points (EPs). A dual section distributed feedback (DFB) quantum cascade laser (QCL) is a prototype of such a system, allowing the controlled coupling of a ladder of cavity Fabry-Perot (FP) modes to a quarter wave shifted DFB mode. Tuning the coupling strength and the gain difference between these two set of modes enables probing the regimes from weak coupling to strong coupling and the robust observation of exceptional point singularities. At these exceptional points, the laser exhibits a sequence of lasing and coherent prefect absorption dynamics1,2 when pumped above transparency. Additionally, the pumping scheme allows the deliberate lifting of the exceptional point degeneracy. These results show that dual section QCL is a perfect platform to study exceptional points because the coupling parameter and system loss can be tuned in a single device.

description: This article introduces an innovative extension of the Juchez distribution, referred to as the length-biased Juchez distribution. This distribution, a specific instance of the broader weighted distribution, is thoroughly explored in terms of mathematical and statistical properties. Parameter estimation is accomplished through the application of maximum likelihood estimation techniques. To highlight the practical significance of this new distribution, a comprehensive analysis is conducted using two real-life lifetime datasets. The findings underscore the relevance and applicability of the proposed distribution in modeling and analyzing diverse datasets.

description: The recently discovered coexistence of superconductivity and charge density wave order in the kagome systems AV3Sb5 (A = K, Rb, Cs) has stimulated enormous interest. According to theory, a vanadium-based kagome system may host a flat band, nontrivial linear dispersive Dirac surface states and electronic correlation. Despite intensive investigations, it remains controversial about the origin of the charge density wave (CDW) order, how does the superconductivity relate to the CDW, and whether the anomalous Hall effect (AHE) arises primarily from the kagome lattice or the CDW order. We report an extensive investigation on Cs(V1-xNbx)3Sb5 samples with systematic Nb doping. Our results show that the Nb doping induces apparent suppression of CDW order and promotes superconductivity; meanwhile, the AHE and magnetoresistance (MR) will be significantly weakened together with the CDW order. Combining with our density functional calculations, we interpret these effects by an antiphase shift of the Fermi energy with respect to the saddle points near M and the Fermi surface centered around Γ. It is found that the former depletes the filled states for the CDW instability and worsens the nesting condition for CDW order; while the latter lifts the Fermi level upward and enlarges the Fermi surface surrounding the Γ point, and thus promotes superconductivity. Our results uncover a delicate but unusual competition between the CDW order and superconductivity.

description: At sufficiently high energies the production of a very large number of particles is kinematically allowed. However, it is well-known that already in the simplest case of a weakly-coupled massive $λφ^4$ theory, $n$-particle amplitudes become non-perturbative in the limit where $n$ scales with energy. In this case, the effective expansion parameter, $λn$, is no longer small and the perturbative approach breaks down. In general, the associated $n$-particle production rates were argued to be described by an exponential that, depending on the specifics of the underlying Quantum Field Theory model, could be either growing or decaying in the large-$n$ regime. We investigate such processes in general settings of Effective Field Theory (EFT), involving arbitrary higher-dimensional operators of $φ$. We perform the resummation of all leading loop corrections arising from EFT vertices for amplitudes at the multiparticle threshold. We find that the net effect of higher-dimensional operators amounts to an exponentially growing factor. We show that if an exponential growth was already generated by the renormalizable interactions, it would then be further enhanced by the EFT contributions. On the other hand, if the multiparticle rates computed in the renormalizable part of the theory were suppressed, this suppression would not be lifted in the EFT.

description: Polarization measurements of thermal radiation from magnetic white dwarf (MWD) stars have been proposed as a probe of axion-photon mixing. The radiation leaving the surface of the MWD is unpolarized, but if low-mass axions exist then photons polarized parallel to the direction of the MWD's magnetic field may convert into axions, which induces a linear polarization dependent on the strength of the axion-photon coupling $g_{aγγ}$. We model this process by using the formalism of axion-photon mixing in the presence of strong-field vacuum birefringence to show that of all stellar types MWDs are the most promising targets for axion-induced polarization searches. We then consider linear polarization data from multiple MWDs, including SDSS J135141 and Grw+70$^\circ$8247, to show that after rigorously accounting for astrophysical uncertainties the axion-photon coupling is constrained to $|g_{aγγ}| \lesssim 5.4 \times 10^{-12}$ GeV$^{-1}$ at 95% confidence for axion masses $m_a \lesssim 3 \times 10^{-7}$ eV. This upper limit puts in tension the previously-suggested explanation of the anomalous transparency of the Universe to TeV gamma-rays in terms of axions. We identify MWD targets for which future data and modeling efforts could further improve the sensitivity to axions.

description: In this study, we explore a new probability distribution termed as the Length-Biased Transmuted Mukherjee-Islam (LBTMI) distribution. This exploration enhances the conventional Transmuted Mukherjee-Islam distribution by integrating a weighted transformation approach. The paper examines the probability density function and the corresponding cumulative distribution function associated with the LBTMI distribution. A comprehensive examination of the unique structural properties of the proposed model is carried out, including the survival function, conditional survival function, hazard function, cumulative hazard function, mean residual life, moments, moment generating function (MGF), characteristic function (CF), cumulant generating function (CGF), likelihood ratio test, ordered statistics, entropy measures, and Bonferroni and Lorenz curves. To ensure precise estimation of model parameters, the study employs the maximum likelihood estimation method, contributing significantly to the advancement of statistical modelling in this domain.

description: This paper investigates a single-server queuing system with heterogeneous service, failure, and maintenance. The proposed model features a server acting as both the main and backup server. System failure can occur at any stage. When a failure happens, instead of stopping the service entirely, the main server functions as a backup, providing service at a reduced rate. Once all jobs in the system have been serviced, the backup server enters the maintenance state. Following the repair process during maintenance, the server transitions to an idle state, awaiting incoming jobs. Explicit expressions for both transient and steady-state behaviours of the system are derived. Additionally, key system performance metrics are discussed in this paper, accompanied by graphical illustrations to visualize system size probabilities and performance indices.
