description: Smart contract transactions associated with security attacks often exhibit distinct behavioral patterns compared with historical benign transactions before the attacking events. While many runtime monitoring and guarding mechanisms have been proposed to validate invariants and stop anomalous transactions on the fly, the empirical effectiveness of the invariants used remains largely unexplored. In this paper, we studied 23 prevalent invariants of 8 categories, which are either deployed in high-profile protocols or endorsed by leading auditing firms and security experts. Using these well-established invariants as templates, we developed a tool Trace2Inv which dynamically generates new invariants customized for a given contract based on its historical transaction data.
 We evaluated Trace2Inv on 42 smart contracts that fell victim to 27 distinct exploits on the Ethereum blockchain. Our findings reveal that the most effective invariant guard alone can successfully block 18 of the 27 identified exploits with minimal gas overhead. Our analysis also shows that most of the invariants remain effective even when the experienced attackers attempt to bypass them. Additionally, we studied the possibility of combining multiple invariant guards, resulting in blocking up to 23 of the 27 benchmark exploits and achieving false positive rates as low as 0.32%. Trace2Inv outperforms current state-of-the-art works on smart contract invariant mining and transaction attack detection in terms of both practicality and accuracy. Though Trace2Inv is not primarily designed for transaction attack detection, it surprisingly found two previously unreported exploit transactions, earlier than any reported exploit transactions against the same victim contracts.

description: Epichloë festucae var. lolii and Epichloë sp. LpTG-3 are filamentous fungal endophytes of perennial ryegrass (Lolium perenne) that have a substantial impact on New Zealand’s agricultural economy by conferring biotic advantages to the host grass. Overall, Epichloë endophytes contribute NZ$200 million to the economy annually, with strain AR37 estimated to contribute NZ$3.6 billion to the New Zealand economy over a 20-year period. This strain produces secondary metabolites, including epoxyjanthitrems, which are a class of indole diterpenes, associated with the observed effects of AR37 on livestock and insect pests. Until very recently, AR37 was intractable to genetic modification but this has changed with the application of CRISPR-Cas9 based gene editing techniques. In this paper, gene inactivation by CRISPR-Cas9 was used to deconvolute the genetic basis for epoxyjanthitrem biosynthesis, including creating an AR37 strain that has been edited to remove the biosynthesis of all indole diterpenes. We show that gene editing of Epichloë can be achieved without off-target events or introduction of foreign DNA (footprint-less) through an AMA1-based plasmid that simultaneously expresses the CRISPR-Cas9 system and selectable marker. Genetic modification events in these transformants were investigated through genome sequencing and in planta chemistry.

title: Exploring the Impact of Values Education on Youth's Attitudes towards African Migrants in Malta

description: Does Values Education have a positive impact on Maltese youths’ attitudes towards African migrants? This study utilized a cross-sectional survey distributed to Maltese youth and quantitative statistical analysis to answer this question. Increasing anti-immigration sentiments throughout Europe have become even more present in Malta following the arrival of thousands of asylum-seekers from the African continent. Negative attitudes towards such migrants have become a source of prejudice and discrimination and an obstacle to the successful integration of African and Maltese communities. Participants’ experience with Values Education is analyzed alongside their attitudes towards African migrants to demonstrate that Values Education is a significant driver of positive attitude formation. This study suggests that this educational approach, more so than a ‘higher education’ alone, is more strongly correlated to positive attitudes towards migrants. Most significantly, Values Education experiences within the classroom which emphasize the application of positive, pro-social values through concepts such as discrimination and racism are most strongly correlated to positive attitudes. It is suggested that cognitive processes of attitude formation are aided by the tendency for such concepts to move learners beyond an abstract conception of values through an emphasis on the logic and rationale behind the application of certain values over others. This may increase the likelihood that such values will be internalized. It is shown that Values Education may act to mitigate the impact of other negative attitude drivers and improve public attitudes towards migrants. As such, Values Education could serve as a potential driver of the positive attitudes necessary for the relations between these two communities to improve thereby increasing the opportunities for their successful integration. To achieve this, educational policy-makers, community leaders, and families in Malta should take note of these implications and work to harmonize and consistently emphasize Values Education activities throughout all spaces within society.

description: Adversarial attacks can drastically degrade performance of recommenders and other machine learning systems, resulting in an increased demand for defence mechanisms. We present a new line of defence against attacks which exploit a vulnerability of recommenders that operate in high dimensional data spaces (the so-called hubness problem). We use a global data scaling method, namely Mutual Proximity (MP), to defend a real-world music recommender which previously was susceptible to attacks that inflated the number of times a particular song was recommended. We find that using MP as a defence greatly increases robustness of the recommender against a range of attacks, with success rates of attacks around 44% (before defence) dropping to less than 6% (after defence). Additionally, adversarial examples still able to fool the defended system do so at the price of noticeably lower audio quality as shown by a decreased average SNR.

description: Vulnerability detection is crucial for ensuring the security and reliability of software systems. Recently, Graph Neural Networks (GNNs) have emerged as a prominent code embedding approach for vulnerability detection, owing to their ability to capture the underlying semantic structure of source code. However, GNNs face significant challenges in explainability due to their inherently black-box nature. To this end, several factual reasoning-based explainers have been proposed. These explainers provide explanations for the predictions made by GNNs by analyzing the key features that contribute to the outcomes. We argue that these factual reasoning-based explanations cannot answer critical what-if questions: What would happen to the GNN's decision if we were to alter the code graph into alternative structures? Inspired by advancements of counterfactual reasoning in artificial intelligence, we propose CFExplainer, a novel counterfactual explainer for GNN-based vulnerability detection. Unlike factual reasoning-based explainers, CFExplainer seeks the minimal perturbation to the input code graph that leads to a change in the prediction, thereby addressing the what-if questions for vulnerability detection. We term this perturbation a counterfactual explanation, which can pinpoint the root causes of the detected vulnerability and furnish valuable insights for developers to undertake appropriate actions for fixing the vulnerability. Extensive experiments on four GNN-based vulnerability detection models demonstrate the effectiveness of CFExplainer over existing state-of-the-art factual reasoning-based explainers.

(Fig. 1A)
 Referred illustrations: Mesorbitolina parva, part of figure 8 in BouDagher-Fadel et al. (2017).
 Mesorbitolina parva (Douglass, 1960) has been described as Orbitolina (Columnorbitolina) absidata by Zhang (1986) from the Langshan Formation of the Lhasa Block. Here we make reference to a tiny image of “ Mesorbitolina parva ” included in Fig. 8 of BouDagher-Fadel et al. (2017) therein showing the stratigraphic ranges and assumed phylogenetic relationships (Fig. 1A). The specimen is here interpreted as an axial section of Praeorbitolina cormyi perpendicular to the median plane comparable to those illustrated by Bosselini et al. (1999, fig. 5a and 5g) from the early Aptian of Ethiopia (Fig. 1 B-C), or own material from Iran (Fig. 1 D-E). It shows a subdivided subembryonic zone overlain by protoconch and deuterconch; a supraembryonic zone is seemingly lacking. The regular presence of short partitions at the top of the deuteroconch (not well discernible) would indicate Praeorbitolina claveli Schlagintweit et al. This example and the following ones give evidence that the established ranges partly include incorrect determinations too.

description: In this work, we explore the generalities of the supercurrent diode effect. As an illustrative example, we examine a model of a two-dimensional superconductor with Rashba-type spin-orbit coupling under an in-plane magnetic field and in the clean limit, which realizes a helical phase. First, we utilize Ginzburg-Landau phenomenology to derive a general formula for the diode efficiency. This is achieved by incorporating higher gradient terms in the Lifshitz invariants, which are responsible for the nonreciprocal superflow. Subsequently, we validate these results through microscopic diagrammatic computation and further estimate correction terms arising from interband pairing correlations. We provide a detailed comparison to prior investigations of this problem conducted within the framework of the quasiclassical approximation based on the Eilenberger equation.

description: Software Defined Radios (SDRs) are growing in popularity in our increasingly multi- standard wireless world. As a result, platforms have been developed to provide powerful and flexible SDR implementations. These platforms tend towards a heterogeneous mix of software (SW) and hardware (HW) components, requiring HW/SW codesign to be an integral part of SDR development. Previous work in the area of SDR codesign has focused on finding optimal HW/SW partitions of a physical layer design that minimize the latency of a single channel. The purpose of this research is to provide a new focus for SDR codesign, that of multi-channel HW/SW codesign. These codesign efforts focus on maximizing the number of simultaneous transmission channels that can run on a codesign SDR platform. A method for deriving models that represent the HW/SW components and the interface between them is presented. The results of this method are general equations describing the HW/SW timing constraints for a multi-channel implementation. An application of the method and models is provided in a Codesign Decision Engine (CDE) that takes as inputs characteristics of a case-study platform, and outputs a predicted number for transmission channel capacity for both a baseline and improved impelmenation. The method and models are verified by actual application performance on the platform under test.
Semiclassical perspective on Landau levels and Hall conductivity in an anisotropic Cubic Dirac Semi-Metal and the peculiar case of star-shaped classical orbits

description: We study an anisotropic cubic Dirac semi-metal subjected to a constant magnetic field. In the case of an isotropic dispersion in the $x$-$y$ plane, with parameters $v_{x}=v_{y}$, it is possible to find exact Landau levels, indexed by the quantum number $n$, using the typical ladder operator approach. Interestingly, we find that the lowest energy level (the zero energy state in the case $k_z=0$) has a degeneracy that is three times that of other states. This degeneracy manifests in the Hall conductivity as a step at zero chemical potential that is 3/2 the size of other steps. Moreover, as $n\to\infty$ we find energies $E_n\propto n^{3/2}$, which means the $n$-th step as a function of chemical potential roughly occurs at a value $μ\propto n^{3/2}$. We propose that these exciting features could be used to identify cubic Dirac semi-metals experimentally. Subsequently, we analyze the anisotropic case $v_{y}=λv_{x}$ with $λ\neq 1$. First, we consider a perturbative treatment around $λ\approx 1$ and find that energies $E_n\propto n^{3/2}$ still holds as $n\to\infty$. To gain further insight into the Landau level structure for a maximum anisotropy, we turn to a semi-classical treatment that reveals interesting star-shaped orbits in phase space that close at infinity. This property is a manifestation of weakly localized states. Despite being infinite in length, these orbits enclose a finite phase space volume and permit finding a simple semi-classical formula for the energy, which again has the form as above. Our findings suggest that both isotropic and anisotropic cubic Dirac semi-metals should leave similar experimental imprints.

description: A current flowing through a superconductor induces a spatial modulation in its superconducting order parameter, characterized by a wavevector $Q$ related to the total momentum of a Cooper pair. Here we investigate this phenomenon in a $p$-wave topological superconductor, described by a one-dimensional Kitaev model. We demonstrate that, by treating $Q$ as an extra synthetic dimension, the current carrying non-equilibrium steady state can be mapped into the ground state of a half-filled two-dimensional Weyl semimetal, whose Fermi surface exhibits Lifshitz transitions when varying the model parameters. Specifically, the transition from Type-I to Type-II Weyl phases corresponds to the emergence of a gapless $p$-wave superconductor, where Cooper pairs coexist with unpaired electrons and holes. Such transition is signaled by the appearance of a sharp cusp in the $Q$-dependence of the supercurrent, at a critical value $Q^*$ that is robust to variations of the chemical potential $μ$. We determine the maximal current that the system can sustain in the topological phase, and discuss possible implementations.

description: Coordination and leadership play a critical role in performance management and set the space for performance by providing feedback coaching, guidance and fostering a teamwork culture of excellence. The role of coordination capabilities in enhancing the performance of business organizations is well documented in strategic management literature. This study explores the influence of coordination and leadership capabilities and how their deployment affects hotel facilities’ performance in Kenya. The study employed a cross-sectional research design in which one hundred and fifty (150) managers of different hospitality facilities in Kenya were surveyed using a questionnaire, and the data were statistically analyzed. The relationship between coordination, leadership capabilities deployment, and hotel performance has had few empirical studies done. The gap in knowledge has been exacerbated by multiple definitions, ambiguity of constructs, contradicting views and little grounding of the theory in empirical observation. The two contracts are dynamic capabilities and affect the host of other aspects that affect performance effectiveness. The research focused on investigating whether coordination and leadership capabilities intrinsic presence in organizations translates to organizational performance in hotels and how coordination and leadership deployment influence performance. The study borrowed from the dynamic-capabilities theory that is grounded in the resource-based view (RBV), which assumes that firms require certain capabilities to be successful and responsive to the (dynamic) changes in their environment by creating, integrating, and modifying their resource base (Teece, 2007; Beske, 2012; Helfat et al., 2007).Like for example, a technological disruption, or post Covid19 hospitality facilities have had to adapt their portfolio of resources. The objective is to assess the effect of deployment of coordinated leadership on hotel performance. The expected result will indicate the influence of coordination and leadership capability deployment and how they impact performance by building valuable insight in assisting hospitality facilities’ organizational effectiveness
The Transport of Extrusive Volcanic Deposits on Jezero Crater Through Paleofluvial Processes

description: Jezero, an impact crater in the Syrtis Major quadrangle of Mars, is generally thought to have amassed a large body of liquid water in its ancient past. NASA spectra of the proposed paleolake interpret the youngest surface unit as olivine-bearing minerals crystallized from magma. In early 2021, the Perseverance rover landed at the leading edge of a fan-delta deposit northwest of Jezero, an area argued to have experienced two distinct periods of fluvial activity. Surface imagery obtained by Perseverance reveal partially buried and unburied vesicular and non-vesicular rocks that appear volcanic in origin, emplaced sometime during the Noachian-Hesperian boundary. The absence of volcanic extrusive features along the fan-delta deposit, however, have made the origin of these ballast deposits a matter of contention among planetary scientists. To establish the origin of these basalt-like rocks, a comparison was made between analogous deposits on the Moenkopi Plateau in Arizona with similar deposits imaged by Perseverance on Jezero. The search for geologic analogs along the Moenkopi Plateau were guided by observable similarities in surface geomorphology, influenced and modified by fluvial, eolian, and past volcanic activity, primarily from the Late Pleistocene-Holocene boundary. By analyzing surface imagery taken by Perseverance and comparing it with the analogue site, we hypothesize that the exposed vesicular rocks imaged by Perseverance were likely transported into the paleolake by geomorphic interactions, specifically fluvial processes similarly to the deposits that were transported along drainage patterns we observed on the Moenkopi Plateau.

Financial Analysis of a Solar Mini Grid  Power Plant Deployment in Kavumu,  DRC: A FINPLAN-Based Approach
Creators: name: Josue, Mugisho Mugaruka
Publisher: name: Zenodo
Year: 2025

description: This report assesses a proposed 30 MW solar mini-grid in Kavumu, DRC using the financial model FINPLAN. The goal was to test project least profitability under varying conditions. The base case uses the current SNEL tariff (194.4 CDF/kWh), assumes production of 125 GWh per year, an exchange rate of 2840 CDF per USD, a discount rate of 17% and an interest rate of 5%.

Key results show that high utilization is essential: if output drops below ~80% of capacity, the net present value turns negative. Under base assumptions, the project only becomes profitable at ~80% utilization and above. However, even with moderate tariff adjustments (e.g. 10% price cuts), the project remains viable if demand stays high. Financing conditions matter too: the model indicates viability only if discount rates stay below about 17%; higher financing costs would make the NPV negative.

Crucially, the analysis highlights currency risk. With DRC’s double-digit inflation, fixed CDF pricing would increase profitability risks. Our findings show that a small franc devaluation (1%) makes the project financial unviable if the tariff is in CDF. By pricing or indexing the tariff in USD, however, the project’s revenue stream becomes stable to local inflation and exchange shift.

In summary, the solar mini-grid can help expand affordable electricity access in the region, but its financial success depends on robust utilization capacity and smart risk management. Allowing USD-indexed tariffs and supporting productive electricity uses are key policy steps to make this renewable energy investment attractive and sustainable.

description: We report discovery and spectroscopic follow-up of 21 astrometric binaries containing solar-type stars and dark companions with masses near 1.4 $M_{\odot}$. The simplest interpretation is that the companions are dormant neutron stars (NSs), though ultramassive white dwarfs (WDs) and tight WD+WD binaries cannot be fully excluded. We selected targets from Gaia DR3 astrometric binary solutions in which the luminous star is on the main sequence and the dynamically-implied mass of the unseen companion is (a) more than $1.25\,M_{\odot}$ and (b) too high to be any non-degenerate star or close binary. We obtained multi-epoch radial velocities (RVs) over a period of 700 days, spanning a majority of the orbits' dynamic range in RV. The RVs broadly validate the astrometric solutions and significantly tighten constraints on companion masses. Several systems have companion masses that are unambiguously above the Chandrasekhar limit, while the rest have masses between 1.25 and 1.4 $M_{\odot}$. The orbits are significantly more eccentric at fixed period than those of typical WD + MS binaries, perhaps due to natal kicks. Metal-poor stars are overrepresented in the sample: 3 out of 21 objects (14%) have [Fe/H]$\sim-1.5$ and are on halo orbits, compared to $\sim$0.5% of the parent Gaia binary sample. The metal-poor stars are all strongly enhanced in lithium. The formation history of these objects is puzzling: it is unclear both how the binaries escaped a merger or dramatic orbital shrinkage when the NS progenitors were red supergiants, and how they remained bound when the NSs formed. Gaia has now discovered 3 black holes (BHs) in astrometric binaries with masses above 9 $M_{\odot}$, and 21 NSs with masses near $1.4\,M_{\odot}$. The lack of intermediate-mass objects in this sample is striking, supporting the existence of a BH/NS mass bimodality over 4 orders of magnitude in orbital period.

description: Slides from the Ocean Sciences Meeting 2022 Keynote Address. As was discussed throughout the conference, the FLUIDITY of our ocean planet is our FUTURE. It is essentially what gives it life. And yet, as we know, our world today is simply, IN TROUBLE. It's safe to say that what we've done with environmental degradation and the issues of social instability are creating a significant amount of uncertainty for all of us, and then there is the unthinkable situation in Ukraine and with the associated crisis in the Black Sea. These issues are overwhelming. And somehow they're all interconnected — climate change, natural disasters, loss of nature in the ocean, overpopulation along the ocean. Addressing these issues with equitable SOLUTIONS is going to be challenging for all of us for the rest of our lives, requiring new governance, new policies, new market approaches, and certainly new technologies which is a focus of the talk. ONE MAJOR SOLUTION I would argue is GEOGRAPHIC, where a so-called Geographic Approach can come to the rescue to help us organize and optimize our knowledge of the ocean (ALL OF OUR KNOWLEDGE, FROM ALL CULTURES, and GEOGRAPHIES) to solve these challenges and to SAVE it. And what I mean by a Geographic Approach is really a Way of Thinking and Problem Solving … … that Integrates spatial data Science & Information Into How We Explore, Designate, Understand, Manage and Communicate about the ocean This approach integrates and supports powerful methodologies: geoanalytics, creating insights and understanding; geovisualization, a language through maps and visualization for communicating the content and the context of our world; geodesign, designing sustainable and inclusive futures; geocollaboration, engaging all the community; and geoaccounting, being able to account for all the factors, setting up balanced measures that are driven by our shared value of the ocean, our knowledge, climate financing and much more. https://www.aslo.org/osm2022/plenary-speakers/

description: We increase the dynamical range of a scanning tunneling microscope (STM) by actively subtracting dominant current-harmonics generated by nonlinearities in the current-voltage characteristics that could saturate the current preamplifier at low junction impedances or high gains. The strict phase relationship between a cosinusoidal excitation voltage and the current-harmonics allows excellent cancellation using the displacement-current of a driven compensating capacitor placed at the input of the preamplifier. Removal of DC currents has no effect on, and removal of the first harmonic only leads to a rigid shift in conductivity that can be numerically reversed by adding the known removal current. Our method requires no permanent change of the hardware but only two phase synchronized voltage sources and a multi-frequency lock-in amplifier to enable high dynamic range spectroscopy and imaging.

description: We demonstrate the unique capabilities of the Wigner function, particularly in its positive and negative parts, for exploring the phase diagram of the spin$-(\frac{1}{2\!}-\!\frac{1}{2})$ and spin$-(\frac{1}{2}\!-\!1)$ Ising-Heisenberg chains. We highlight the advantages and limitations of the phase space approach in comparison with the entanglement concurrence in detecting phase boundaries. We establish that the equal angle slice approximation in the phase space is an effective method for capturing the essential features of the phase diagram, but falls short in accurately assessing the negativity of the Wigner function for the homogeneous spin$-(\frac{1}{2}\!-\!\frac{1}{2})$ Ising-Heisenberg chain. In contrast, we find for the inhomogeneous spin$-(\frac{1}{2}\!-\!1)$ chain that an integral over the entire phase space is necessary to accurately capture the phase diagram of the system. This distinction underscores the sensitivity of phase space methods to the homogeneity of the quantum system under consideration.

description: Ferroelectric field effect transistor (FeFET) memory has shown the potential to meet the requirements of the growing need for fast, dense, low-power, and non-volatile memories. In this paper, we propose a memory architecture named crossed-AND (C-AND), in which each storage cell consists of a single ferroelectric transistor. The write operation is performed using different write schemes and different absolute voltages, to account for the asymmetric switching voltages of the FeFET. It enables writing an entire wordline in two consecutive cycles and prevents current and power through the channel of the transistor. During the read operation, the current and power are mostly sensed at a single selected device in each column. The read scheme additionally enables reading an entire word without read errors, even along long bitlines. Our Simulations demonstrate that, in comparison to the previously proposed AND architecture, the C-AND architecture diminishes read errors, reduces write disturbs, enables the usage of longer bitlines, and saves up to 2.92X in memory cell area.

description: We demonstrate and verify the in-situ addition of a collecting lens for electroluminescence experiments to an existing scanning tunneling microscope. We fabricate a simple clip-on lens that we reversibly attach at the sample plate via regular sample transfer tools to collimate the light emitted from a plasmonic tunneling junction to the viewport ordinarily used for optical access. The proximity of the lens to the tunneling junction allows us to exploit the full numerical aperture which helps us achieve good collection efficiencies, demonstrating the quick turnaround of converting an existing setup with optical access into a practical scanning luminescence microscope. We verify the function of the clip-on lens by measuring the bias dependent plasmon of Au, Ag, and spatial luminescence maps.

description: Abstract

Empowering rural youth in agriculture through peer learning can unlock the sector’s potential and drive sustainable growth. This study, conducted in Jerash, Jordan, surveyed 54 participants aged 25 to 30 following two 30-minute interactive sessions focused on agricultural entrepreneurship. These sessions covered business planning, marketing, and sustainable farming practices. The participant group had a near-equal gender distribution and varied educational backgrounds, with many holding college degrees. The analysis revealed that education level significantly affected participants' pre-session knowledge, and there was a strong positive correlation between pre-session knowledge and post-session attitudes toward agricultural entrepreneurship. Interestingly, age did not have a notable influence on these attitudes. The study also found gender disparities in post-session knowledge scores. While education level did not significantly affect participants’ intentions to start an agricultural business, age positively correlated with post-session knowledge scores, particularly after the sessions. These findings emphasize the importance of educational diversity, targeted learning programs, and the role of prior knowledge in shaping attitudes toward entrepreneurship. The study also draws attention to gender disparities and the influence of socioeconomic factors on education, underscoring the need for inclusive strategies to empower rural youth in agriculture and promote sustainable growth.

description: Record of Palorbitolinoides orbiculata Zhang, 1986 and Palorbitolinoides hedini Cherchi & Schroeder, 1980
 Referred illustration: Palorbitolinoides orbiculata Zhang, figure 8.8, Palorbitolinoides hedini Cherchi & Schroeder, 1980, figure 8.9 in BouDagher-Fadel et al. (2017).
 Both species have been described from Aptian-Albian limestones of Tibet (Cherchi & Schroeder, 1980; Zhang, 1986). A third species, Palorbitolinoides tenuis Zhang, 1986, is considered a junior synonym of the type-species P. hedini by Schroeder et al. (2010). The differences of both species refer to the size and complexity of the embryo. The diameter of the central embryonic chamber is 0.21-0.4 mm in P. orbiculata (see Zhang, 1986, table page 207) against 0.45-0.7 mm in P. hedini (see Schroeder et al., 2010, p. 60). The embryo of P. hedini is much larger as in P. orbiculata, flattened, and with a well developed and inflated peri-embryonic zone. In addition, the partitions at the top of the embryonic chamber produce a system of small alveoli of different lengths. Both specimens illustrated by BouDagher-Fadel et al. (2017) display a hemi-spherical embryonic chamber (diameter ~0.31-~ 0.39 mm) with rather short partitions of seemingly equal length. They are interpreted as belonging to P. orbiculata. The stratigraphy of the two species P. orbiculata and P. hedini appears not as well fixed as other Orbitolininae (Cherchi & Schroeder, 1980, 2013; Zhang, 1986; Marcoux et al., 1987; BouDagher-Fadel et al., 2017). Transitional types between P. orbiculata and P. hedini have been illustrated by Marcoux et al. (1987, pl. 2, figs. 2-4) from the late Aptian of Tibet. It is worth noting that representatives of Palorbitolinoides co-occuring with Mesorbitolina aperta (Erman) in the upper Albian of the Kazhdumi Formation in SW Iran are currently under study. Also with respect to the palaeobiogeographic distribution there seems to be some kind of dissens as Cherchi & Schroeder (2013) considered Palorbitolinoides cf. orbiculata as a typical taxon of the southern Neotethysian margin.

description: The largely unexplored decameter radio band (10-30 MHz) provides a unique window for studying a range of astronomical topics, such as auroral emission from exoplanets, inefficient cosmic ray acceleration mechanisms, fossil radio plasma, and free-free absorption. The scarcity of low-frequency studies is mainly due to the severe perturbing effects of the ionosphere. Here we present a calibration strategy that can correct for the ionosphere in the decameter band. We apply this to an observation from the Low Frequency Array (LOFAR) between 16 to 30 MHz . The resulting image covers 330 square degrees of sky at a resolution of 45", reaching a sensitivity of 12 mJy/beam. Residual ionospheric effects cause additional blurring ranging between 60 to 100". This represents an order of magnitude improvement in terms of sensitivity and resolution compared to previous decameter band observations. In the region we surveyed, we have identified four fossil plasma sources. These rare sources are believed to contain old, possibly re-energised, radio plasma originating from previous outbursts of active galactic nuclei. At least three of them are situated near the center of low-mass galaxy clusters. Notably, two of these sources display the steepest radio spectral index among all the sources detected at 23 MHz. This indicates that fossil plasma sources constitute the primary population of steep-spectrum sources at these frequencies, emphasising the large discovery potential of ground-based decameter observations.
