description: We introduce and demonstrate a hybrid optically pumped magnetometer (HOPM) that simultaneously measures one dc field component and one rf field component quadrature with a single atomic spin ensemble. The HOPM achieves sub-pT/$\sqrt{\mathrm{Hz}}$ sensitivity for both dc and rf fields, and is limited in sensitivity by spin projection noise at low frequencies and by photon shot noise at high frequencies. We demonstrate with the HOPM a new application of multiparameter quantum sensing: background-cancelling spread spectrum magnetic communication. We encode a digital message as rf amplitude, spread among sixteen channels from \SI{29}{\kilo\hertz} to \SI{33}{\kilo\hertz} in a noisy magnetic environment, and observe quantum-noise-limited rf magnetic signal recovery enabled by quantum-noise-limited dc noise cancellation, reaching noise rejection of \SI{15}{\decibel} at \SI{100}{\hertz} and more than \SI{20}{\decibel} at \SI{60}{\hertz} and below. We measure signal fidelity versus signal strength and extrinsic noise in communication of a short text message. The combination of high sensitivity, quantum-noise-limited performance, and real-world application potential makes the HOPM ideally suited for study of high-performance multiparameter quantum sensing.

description: The chemical investigation of whole plants Euphorbia stracheyi Boiss from China led to the isolation of one new ent-kaurane diterpene, ent-Kaurane-16β,17,19-triol-3-one (1), along with three known ent-kaurane diterpenoids (2–4) as ent-Kaurane-3α,16β,17-triol (2)，ent-16S,17-dihydroxy-kaurane-3-one (3) and ent-3S,16S,17-trihydroxy-kaurane-2-one (4). Their structures were elucidated by extensive spectroscopic analyses including 1D, 2D NMR, HR-ESI-MS, and by comparison with the literature. Compound 2 was a new natural product and firstly isolated from nature, while compounds (3–4) were isolated from E. stracheyi for the first time. All isolated compounds (1–4) were evaluated for their cytotoxic activities against five human cancer cell lines (including A-549, SMMC-7721, HL-60, MCF-7 and SW-480).

The Roman inscriptions of Deva (Chester)

Publisher: name: Archaeology Data Service
Year: 2018

description: Journal of the Chester Archaeological Society, 3, 120-150
description: The author translates and interprets inscriptions from a number of Roman stones recovered in Chester, including altars, fragments from monumental inscriptions, centurial stones and tombstones. It is observed that none of the monuments found recently in the north wall of the city is of later date than the second half of the second century AD. Some historical context is given to support the suggestion that the city walls were enlarged during the reign of Septimius Severus, reusing some material, including tombstones from about a century earlier.

Amplifying Non-Resonant Production of Dark Sector Particles in Scattering Dominance Regime

description: We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard Model particle sources. Our analysis reveals that in the scattering dominance regime, with a significantly smaller scattering mean free path $λ_{\rm sca}$ compared to the absorption mean free path $λ_{\rm abs}$, the nonresonant production of sterile states can experience an enhancement by a factor of $λ_{\rm abs}/λ_{\rm sca}$. This phenomenon is demonstrated within the context of kinetic mixing dark photon production at a reactor, precisely satisfying this condition. By incorporating this collisional enhancement, we find that the current sensitivity to the mixing parameter $ε$ for dark photons in the TEXONO experiment can be significantly improved across a range spanning from tens of eV to MeV. This advancement establishes the most stringent laboratory constraint within this mass spectrum for the dark photon. Sterile neutrino production, however, does not exhibit such enhancement, either due to the failure to meet the scattering dominance criterion or the neutrino damping in resonant production.

description: Metadata matters, especially if you wish your digital objects to live long and flourish. Currently most people turn to search engines when in need of information on any subject. But no search engine knows anything other than what it is told. Telling is not possible without names or locations. In the era of digitalisation, high quality machine-readable metadata and machine-actionable identifiers have become more important than ever before.

With this in mind, the National Library of Finland has been providing persistent identifier services to higher education and cultural heritage organisations since the late 1990s. This free-of-charge, actionable and persistent identifier URN – Uniform Resource Name – is an internet standard able to encompass other identifiers under the same umbrella. URN is not limited to identifying documents, but rather it can be assigned to any kind of digital object. The functionalities of URNs are rather similar to DOIs and they can be used in similar ways, but they are not mutually exclusive. The URN standard includes sophisticated functionalities that can be tailored to the namespaces. However, there have been no practical implementations of this as of yet.

Based on feedback from URN end users as well as our in-house specialists, we now have developed new versions of the National Library of Finland’s open-source URN harvester and resolver. This aims to improve the use of persistent identifiers as means of interaction. The new features make integration of URNs easier and smoothen the flows of information. For example, the current URN resolver distinguishes between normal URLs and legal deposit URLs, allowing it to inform the end user if the object is only available in the legal deposit collection. Previously, mapping functioned as one-to-one. Now mapping functions as one-to-many.

By using URNs, one serves libraries, search engines, and, at the end of the day and most importantly, the end users. URNs realise FAIR by making the identified object findable, accessible and re-usable.

description: In this study, a series of novel ferulic and caffeic acid dimers was designed and synthesised, and their multifunctional properties against Alzheimer’s disease (AD) were evaluated. Results showed that our multifunctional strategy was great supported by enhancing the inhibition of Aβ1–42 self-induced aggregation. Moreover, 7b also had potent protective effects against glutamate-induced cell death without significant cell toxicity in mouse hippocampal neuronal HT22 cells and 10c effectively scavenged diphenylpicrylhydrazyl free radicals. Collectively, these data strongly encourage further optimisation of 7b as a new hit to develop multifunctional agents for the treatment of AD.

description: Analytical results obtained within Landau-Ginzburg-Devonshire approach and effective media models, predict that the synergy of size effects and Vegard stresses can significantly enhance the electrocaloric cooling (up to 7 times) of the BaTiO3 nanoparticles in comparison with a bulk BaTiO3. To compare with the considered effective media models, we measured the capacitance-voltage and current-voltage characteristics of the dense nanocomposites consisting of (28-35) vol.% BaTiO3 nanoparticles incorporated in organic polymers and determined experimentally the effective dielectric permittivity and losses of the composites. Generalizing obtained analytical results, various ferroelectric nanoparticles spontaneously stressed by elastic defects, such as oxygen vacancies or any other elastic dipoles, which create a strong chemical pressure, can cause the giant electrocaloric response of dense ferroelectric nanocomposites. We have shown that the advantages of the studied lead-free dense nanocomposites are the good tunability of electrocaloric cooling temperature due to the size effects in ferroelectric nanoparticles and the easy control of the high electrocaloric cooling by electric fields. This makes the dense ferroelectric nanocomposites promising for cooling of conventional and innovative electronic elements, such as FETs with high-temperature superconductor channels.

description: The NCAA has contended for more than a century that its revered tradition of amateurism carves out a special legal status for its “student-athletes.” In recent years a bevy of litigation on antitrust and labor law grounds has steadily eroded that long held position. Already, college athletics has experienced significant change, with a steady increase in the economic rights of college athletes. The next debate will be over the employment status of these athletes. This paper considers that debate as a question of law. We discuss the National Labor Relations Act and the Fair Labor Standards Act, as applied in current and past cases before the National Labor Relations Board and in federal court. We then consider the concept of players unions in college athletics and discuss implications for tax liability and Title IX compliance. We conclude that under the different standards of the NLRA and FLSA, some college athletes should be considered employees— especially those in the most heavily commercialized sports of Autonomy conference football and basketball—and some should not. Critically, we demonstrate the difficulty of differentiating between which are employees and which are not, given the arbitrary nature of the relevant legal standards and the heterogeneity of the day-to-day realities of college athletes across sports, schools, and levels of competition.
Strong relevance of Zinc impurity in the spin-$\frac{1}{2}$ Kagome quantum antiferromagnets: a variational study

description: Copper hydroxyhalide materials herbertsmithite ZnCu$_{3}$(OH)$_{6}$Cl$_{2}$ and Zn-barlowite ZnCu$_{3}$(OH)$_{6}$FrBr are thought to be the best realizations of the spin-$\frac{1}{2}$ Kagome quantum antiferromagnetic Heisenberg model and are widely believed to host a spin liquid ground state. However, the exact nature of such a novel state of matter is still under strong debate, partly due to the complication related to the occupation disorder between the Zinc and the Copper ions in these systems. In particular, recent nuclear magnetic resonance measurements indicate that the magnetic response of the Kagome plane is significantly spatial inhomogeneous, even though the content of the misplaced Zinc or Copper ions is believed to be very small. Here we use extensive variational optimization to show that the well known $U(1)$-Dirac spin liquid state is extremely sensitive to the introduction of the nonmagnetic Zinc impurity in the Kagome plane. More specifically, we find that the Zinc impurities can significantly reorganize the local spin correlation pattern around them and induce strong spatial oscillation in the magnetic response of the system. We argue that this is a general trend in highly frustrated quantum magnet systems, in which the nonmagnetic impurity may act as strongly relevant perturbation on the emergent resonating valence bond structure in their spin liquid ground state. We also argue that the strong spatial oscillation in the magnetic response should be attributed to the free moment released by the doped Zinc ions and may serve as the smoking gun evidence for the Dirac node in the $U(1)$ Dirac spin liquid state on the Kagome lattice.

description: We consider Hamiltonian formulation of a dynamical system forced to move on a submanifold $G_α(q^A)=0$. If for some reasons we are interested in knowing the dynamics of all original variables $q^A(t)$, the most economical would be a Hamiltonian formulation on the intermediate phase-space submanifold spanned by reducible variables $q^A$ and an irreducible set of momenta $p_i$, $[i]=[A]-[α]$. We describe and compare two different possibilities for establishing the Poisson structure and Hamiltonian dynamics on an intermediate submanifold: Hamiltonian reduction of the Dirac bracket and intermediate formalism. As an example of the application of intermediate formalism, we deduce on this basis the Euler-Poisson equations of a spinning body, establish the underlying Poisson structure, and write their general solution in terms of the exponential of the Hamiltonian vector field.

description: La revue systématique est devenue peu à peu l’étalon-or pour identifier, analyser, et synthétiser les données scientifiques les plus robustes pour répondre à une problématique donnée, quelle que soit la discipline ou le secteur concerné. Elle est un outil important pour les politiques publiques et les pratiques fondées sur des données probantes qui visent à rapprocher la recherche de la prise de décision. Pourtant, il existe une multitude d’autres approches permettant une revue systématique. Ainsi, dans ce document, nous proposons un survol de ces différentes méthodes de revues systématiques afin de permettre aux chercheurs et décideurs qui souhaitent réaliser ou utiliser de telles démarches de choisir la plus adaptée à leurs contexte et question de recherche. Elles se distinguent des revues de type « état de l’art » par leur processus systématique, rigoureux et transparent. Chaque type de revue est décrit dans le document selon ses caractéristiques, ses étapes, ses forces, ses défis, et ses limites. La lecture de cette analyse sera autant utile aux intervenants qui souhaitent développer des actions et des politiques fondées sur des données scientifiques qu’aux étudiants désirant proposer un état des lieux systématique et rigoureux des connaissances pour construire la problématique de leur mémoire ou de leur thèse de recherche universitaire. https://www.ceped.org/wp

description: Comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC/ToF-MS) was used for the analysis of thia-arenes and aza-arenes in standard mixtures containing 45 polycyclic aromatic compounds (PACs), and in the aromatic fraction of snowpack samples collected from the Athabasca oil sands area of Alberta, Canada. The GC columns used included a shape-selective liquid-crystalline stationary phase (LC-50) and a high-polarity ionic-liquid stationary phase (SLB-IL60), both in the first dimension. A fast diffusion and low-polarity nano-stationary phase (NSP-35) and a mid-polarity stationary phase (Rxi-17), were used in the second dimension, respectively. Both configurations showed good repeatability for retention times in the first and second dimensions, peak areas and peak heights. Instrument detection limits ranged from 0.5 to 10 pg µL−1 for both configurations. In general, the LC-50×NSP-35 configuration favoured the separation of isomeric compounds by using more of the 2D chromatographic space available (>80%), particularly for compounds with molecular mass >160 u. Therefore, LC-50×NSP-35 was recommended for the analysis of thia-arenes and alkylated PAHs in environmental samples collected from the oil sands area. Alternatively, the SLB-IL60×Rxi-17 configuration favoured molecular similarity grouping over isomer separation. This was observed for a group of aza-arenes (i.e. carbazoles, benzo[a]carbazoles and alkylated-derivatives), which were resolved from other PACs and from the sample matrix. The risk of false positives and overestimations in the analysis of thia-arenes, aza-arenes and alkylated PACs in one-dimension GC/MS was explored and further reduced by using GC×GC/ToF-MS with LC-50×NSP-35 and SLB-IL60×Rxi-17.

description: We study the transverse momentum ($p_T$) spectra of neutral pions and identified charged hadrons produced in proton--proton ($pp$), deuteron--gold ($d$--Au), and gold--gold (Au--Au) collisions at the center of mass energy $\sqrt{s_{NN}}=200$ GeV. The study is made in the framework of a multi-source thermal model used in the partonic level. It is assumed that the contribution to the $p_T$-value of any hadron comes from two or three partons with an isotropic distribution of the azimuthal angle. The contribution of each parton to the $p_T$-value of a given hadron is assumed to obey any one of the standard (Maxwell-Boltzmann, Fermi-Dirac, and Bose-Einstein) distributions with the kinetic freeze-out temperature and average transverse flow velocity. The $p_T$-spectra of the final-state hadrons can be fitted by the superposition of two or three components. The results obtained from our Monte Carlo method are used to fit the experimental results of the PHENIX and STAR Collaborations. The results of present work serve as a suitable reference baseline for other experiments and simulation studies.

description: Capsule: Wood Warblers Phylloscopus sibilatrix showed significant selection for tree species and woodland characteristics at staging and wintering sites in sub-Saharan Africa. Aims: To investigate home range size, habitat and tree species selection of Wood Warblers at a staging site in Burkina Faso (Koubri) and a wintering site in Ghana (Pepease). Methods: Comparing habitat recorded at locations of radio-tagged birds and at control points, we investigated whether there was habitat and tree species selection. We also compared home range size of individual birds between the two sites. Results: Home range size did not differ between the two sites. There was significant selection for tree species at both Koubri and Pepease: Anogeissus leiocarpus and Albizia zygia, respectively. At Koubri, there was significant avoidance of the most common tree species (Azadirachta indica, Mangifera indica (both non-native), Vitellaria paradoxa and Acacia spp.). In addition, there was a preference for taller trees and greater tree density at both sites. However, the probability of a point being used declined with increasing number of taller (>14 m) trees. Conclusion: Fine-scale selection of woodland habitats suggests that Wood Warblers are likely to suffer the consequences of ongoing land-use change in their West African wintering grounds.

description: This paper performs the first cosmological parameter analysis of the KiDS-1000 data with second- and third-order shear statistics. This work builds on a series of papers that describe the roadmap to third-order shear statistics. We derive and test a combined model of the second-order shear statistic, namely the COSEBIs and the third-order aperture mass statistics $\langle M_\mathrm{ap}^3\rangle$ in a tomographic set-up. We validate our pipeline with $N$-body simulations that mock the fourth Kilo Degree survey data release. To model the second- and third-order statistics, we use the latest version of \textsc{HMcode2020} for the power spectrum and \textsc{BiHalofit} for the bispectrum. Furthermore, we use an analytic description to model intrinsic alignments and hydro-dynamical simulations to model the effect of baryonic feedback processes. Lastly, we decreased the dimension of the data vector significantly by considering for the $\langle M_\mathrm{ap}^3\rangle$ part of the data vector only equal smoothing radii, making a data analysis of the fourth Kilo Degree survey data release using a combined analysis of COSEBIs third-order shear statistic possible. We first validate the accuracy of our modelling by analysing a noise-free mock data vector assuming the KiDS-1000 error budget, finding a shift in the maximum-a-posterior of the matter density parameter $ΔΩ_m< 0.02\, σ_{Ω_m}$ and of the structure growth parameter $ΔS_8 < 0.05\, σ_{S_8}$. Lastly, we performed the first KiDS-1000 cosmological analysis using a combined analysis of second- and third-order shear statistics, where we constrained $Ω_m=0.248^{+0.062}_{-0.055}$ and $S_8=σ_8\sqrt{Ω_m/0.3}=0.772\pm0.022$. The geometric average on the errors of $Ω_\mathrm{m}$ and $S_8$ of the combined statistics increased compared to the second-order statistic by 2.2.

description: We have developed a new machine learned interatomic potential for the prototypical austenitic steel Fe$_{7}$Cr$_{2}$Ni, using the Gaussian approximation potential (GAP) framework. This new GAP can model the alloy's properties with close to density functional theory (DFT) accuracy, while at the same time allowing us to access larger length and time scales than expensive first-principles methods. We also extended the GAP input descriptors to approximate the effects of collinear spins (Spin GAP), and demonstrate how this extended model successfully predicts structural distortions due to antiferromagnetic and paramagnetic spin states. We demonstrate the application of the Spin GAP model for bulk properties and vacancies and validate against DFT. These results are a step towards modelling the atomistic origins of ageing in austenitic steels with higher accuracy.

description: Experimental studies have suggested benzophenone-3 (BP-3), a sunscreen ingredient, may have endocrine-disrupting properties. A cohort of girls were recruited at ages 6–7 years and returned semi-annually for pubertal maturation staging, provided blood for serum hormone analyses [estradiol, estrone, testosterone, dehydroepiandrosterone-sulfate (DHEA-S)], and urine to measure BP-3 concentrations. We found a significant negative linear association between amount of reported sunscreen use and testosterone levels at the onset of puberty (N = 157, adjusted β = −0.0163, 97.5% CI:-0.0300,-0.0026). The 2nd quartile of the BP-3 biomarker had earlier thelarche compared to the 1st quartile (N = 282, adjusted HR = 1.584, 97.5% CI:1.038,2.415). Results suggest that higher report of sunscreen use may be associated with lower testosterone levels at thelarche and a non-linear relationship between the BP-3 urinary biomarker and onset of puberty, although the clinical significance of the finding is limited and may be a random effect. Improved methods of BP-3 exposure characterization are needed.

description: Recently, the experimental measurements of the branching ratios and different polarization asymmetries for the processes occurring through flavor-changing-charged current $b\rightarrow cτ\overlineν_τ$ transitions by BABAR, Belle, and LHCb show some sparkling differences with the corresponding SM predictions. Assuming the left handed neutrinos, we add the dimension-six vector, (pseudo-)scalar, and tensor operators with complex WCs to the SM WEH. Together with 60%, 30% and 10% constraints coming from the branching ratio of $B_{c}\toτ\barν_τ$, we analyze the parametric space of these new physics WCs accommodating the current anomalies in the purview of the most recent HFLAV data of $R_{τ/{μ,e}}\left(D\right)$, $R_{τ/{μ,e}}\left(D^*\right)$ and Belle data of $F_{L}\left(D^*\right)$ and $P_τ\left(D^*\right)$. Furthermore, we derive the sum rules which correlate these observables with $R_{τ/{μ,e}}\left(D\right)$ and $R_{τ/{μ,e}}\left(D^*\right)$. Using the best-fit points of the new complex WCs along with the latest measurements of $R_{τ/{μ,e}}\left(D^{(*)}\right)$, we predict the numerical values of the observable $R_{τ/\ell}\left(Λ_c\right)$, $R_{τ/μ}\left(J/ψ\right)$ and $R_{τ/\ell}\left(X_c\right)$ from the sum rules. Apart from finding the correlation matrix among the observables under consideration, we plot them graphically which is useful to discriminate different NP scenarios. Finally, we study the impact of these NP couplings on various angular and the CP triple product asymmetries, that could be measured in some ongoing and future experiments. The precise measurements of these observables are important to check the SM and extract the possible NP.

Critical View on Mediation of Domestic Violence
Creators: name: Mrwebi, Mandisi
Publisher: name: CSDA

description: This is a compilation of papers that critically examines the suitability of mediation as a dispute resolution mechanism in cases of domestic violence (DV). Drawing on domestic violence statistics from UNICEF, WHO, and Statistics South Africa, the analysis highlights DV's pervasive impact and considers how diverse cultural, social, and legal contexts influence mediation's application, notably in Scandinavian countries, the UK, USA, and various developing regions. While alternative dispute resolution (ADR) has been celebrated historically for promoting societal harmony, this study underscores the need to question mediation’s effectiveness and safety in DV cases, where power imbalances and psychological trauma often complicate equitable negotiation. This perspective is contextualized within the broader role of USAID, which supports rule of law initiatives in developing countries, aiming to fortify accessible, fair justice systems.

The discussion distinguishes mediation from other ADR forms, such as arbitration and conciliation, which may sometimes offer clearer frameworks for DV cases. In light of global best practices, this paper calls for a recalibration of mediator competencies and ethical standards tailored specifically to DV contexts. Ultimately, while mediation remains an invaluable tool within ADR, its role in domestic violence demands a refined, cautious approach to ensure victim protection and justice, emphasizing the continuous professionalization of mediators across cultural and legal landscapes.

description: Objectives: Combined oral contraceptives (COCs) are the most widely used contraceptive method in Europe. Paradoxically, rates of unintended pregnancy and abortion are still remarkably high. A lack of knowledge about COCs is often reported to lead to poor adherence, suggesting an unmet need for adequate contraceptive counselling. Our objective was to investigate the impact on the knowledge level of users of a structured approach to deliver contraceptive information for a first COC prescription. Methods: The Oral Contraception Project to Optimise Patient Information (CORALIE) is a multicentre, prospective, randomised study conducted in France between March 2009 and January 2013. The intervention involved providing either an ‘essential information’ checklist or unstructured counselling to new COC users. The outcome measure was a questionnaire that assessed whether the information provided to the new user by the gynaecologist had been correctly understood. Results: One hundred gynaecologists and an expert committee used the Delphi method to develop an ‘essential information’ checklist, after which 161 gynaecologists were randomised to two groups. Group I (n = 81) used the checklist with 324 new COC users and group II (n = 80) delivered unstructured information to 307 new COC users. The average score for understanding the information delivered during the visit was significantly higher in women in group I than in the women in group II, even after adjustment for age and previous history of pregnancy: 16.48/20 vs 14.27/20 (p Conclusion: Delivering structured information for a first COC prescription is beneficial for understanding contraception. Our tool could ultimately contribute to increased adherence and should be investigated in a prospective study of long-term outcomes.

description: In this study, we propose to evaluate the use of deep learning methods for semantic classification at the sentence level to accelerate the process of corpus building in the field of humanities and linguistics, a traditional and time-consuming task. We introduce a novel corpus comprising around 2500 sentences spanning from 300 BCE to 900 CE including sexual semantics (medical, erotica, etc.). We evaluate various sentence classification approaches and different input embedding layers, and show that all consistently outperform simple token-based searches. We explore the integration of idiolectal and sociolectal metadata embeddings (centuries, author, type of writing), but find that it leads to overfitting. Our results demonstrate the effectiveness of this approach, achieving high precision and true positive rates (TPR) of respectively 70.60% and 86.33% using HAN. We evaluate the impact of the dataset size on the model performances (420 instead of 2013), and show that, while our models perform worse, they still offer a high enough precision and TPR, even without MLM, respectively 69% and 51%. Given the result, we provide an analysis of the attention mechanism as a supporting added value for humanists in order to produce more data.

description: Single-step retrosynthesis (SSR) in organic chemistry is increasingly benefiting from deep learning (DL) techniques in computer-aided synthesis design. While template-free DL models are flexible and promising for retrosynthesis prediction, they often ignore vital 2D molecular information and struggle with atom alignment for node generation, resulting in lower performance compared to the template-based and semi-template-based methods. To address these issues, we introduce Node-Aligned Graph-to-Graph (NAG2G), a transformer-based template-free DL model. NAG2G combines 2D molecular graphs and 3D conformations to retain comprehensive molecular details and incorporates product-reactant atom mapping through node alignment which determines the order of the node-by-node graph outputs process in an auto-regressive manner. Through rigorous benchmarking and detailed case studies, we have demonstrated that NAG2G stands out with its remarkable predictive accuracy on the expansive datasets of USPTO-50k and USPTO-FULL. Moreover, the model's practical utility is underscored by its successful prediction of synthesis pathways for multiple drug candidate molecules. This not only proves NAG2G's robustness but also its potential to revolutionize the prediction of complex chemical synthesis processes for future synthetic route design tasks.

description: Chirality is probably the most mysterious among all symmetry transformations. Very readily broken in biological systems, it is practically absent in naturally occurring inorganic materials and is very challenging to create artificially. Chiral optical wavefronts are often used for the identification, control and discrimination of left- and right-handed biological and other molecules. Thus, it is crucially important to create materials capable of chiral interaction with light, which would allow one to assign arbitrary chiral properties to a light field. In this paper, we utilized van der Waals technology to assemble helical homostructures with chiral properties (e. g. circular dichroism). Because of the large range of van der Waals materials available such helical homostructures can be assigned with very flexible optical properties. We demonstrate our approach by creating helical homostructures based on multilayer As$_2$S$_3$, which offers the most pronounced chiral properties even in thin structures due to its strong biaxial optically anisotropy. Our work showcases that the chirality of an electromagnetic system may emerge at an intermediate level between the molecular and the mesoscopic one due to the tailored arrangement of non-chiral layers of van der Waals crystals and without additional patterning.

description: Argues, from the large sample of Roman coins from Chester, for the possibility of a pre-Flavian base in the area for sea-borne operations against the coasts of north Wales and north-west England. Full legionary occupation may have been delayed until the evacuation of Scotland c AD 87. Subsequent occupation reflected changes in frontier policy. A sharp decline in coin loss after 350 poses serious questions regarding the nature and status of Chester.
