(Fig. 7)
Material examined. Holotype female, rice field, Yasothon Province, Thailand, 15° 44.688ʹ N, 104° 13.244ʹ E, 24- x-2010 (RMNH). Paratype: One female, rice field, Amnat Chareon Province, 25-x-2010 (RMNH); one female, Rice field, Sisaket Province, 14° 59ʹ 28.4ʺ N, 104° 22ʹ 56.7ʺ E, 5-x-2010 (RMNH).
Diagnosis. Genital field with one small platelet with 2–3 acetabula, located anteriorly to posterior two plates. The latter consisting of one plate with 7–9 acetabula and one with 20 acetabula. P4 with small setal tubercles.
Description. Female: Idiosoma; dorsal length 1045 (884–1025); width 810 (784–810). Posterior margin of fourth coxae slightly concave. Medial margin of fourth coxal plates as long as medial margin of third coxal plates. Genital field 454 (445) wide, sloping posteriorly (slope approx. 45°) with acetabula on weakly developed and fragmented platelets that are variable in shape and extending beyond the gonopore (fig 7A); one small platelet with (3–4) acetabula located anterior to two major posterior platelets (fig 7A); one posterior platelet with 7–9 acetabula, the other with 19 acetabula curved around an enlarged central acetabulum. Gonopore 186 (156) long. Pre-genital sclerite sickle-shaped, post-genital sclerite rectangular. Length of P1-5: 49, 219, 109, 186, 77. Ventral margin of P2 rugose and slightly convex, P4 stocky with small setal tubercles. Length of I-leg-4–6: 186, 194, 162. Length of IVleg-4–6: 235, 259, 211.
Etymology. Named for its occurrence in rice fields.
Remarks. The left and right large acetabular plates of the holotype differ, one being more fragmented. However, in the paratype both genital plates are similar, and are like the left genital plate of the holotype. The new species is similar to P. dadayi (Piersig, 1900), but differs in a less slender palp, and sloping posterior genital plates that extend well beyond the gonopore. Piona platyura Jin & Guo, 1992 has somewhat similarly shaped genital plates, but the small anterior platelet is fused to the posterior platelet, and P4 has a large ventral extension which is absent in the new species.

description: It is often argued that {\it all the information of a gravitational theory is encoded in the surface term of the action}; which means one can find several physical quantities just from the surface term without incorporating the bulk part of the action. This has been observed in various instances; e.g. derivation of the Einstein's equations, surface term calculated on the horizon leads to entropy, etc. Here I investigate the role of it in the context of entropy function and entropy of extremal near horizon black holes. Considering only the Gibbons-Hawking-York (GHY) surface term to define an entropy function for the extremal near horizon black hole solution, it is observed that the extremization of such function leads to the exact value of the horizon entropy. This analysis again supports the previous claim that there exists a ``{\it holographic}'' nature in the gravitational action -- surface term contains the information of the bulk.

description: Rare-earth Zintl compound EuIn$_2$As$_2$ has been theoretically recognized as a candidate for realizing an intrinsic antiferromagnetic (AFM) bulk axion insulator and a higher-order topological state, which provides a fertile platform to explore novel topological transport phenomena. However, the axion state has yet to be realized because EuIn$_2$As$_2$ is highly hole-doped. Here, we synthesized a series of high-quality Ca-doped EuIn2As2 (Ca$_x$Eu$_{1-x}$In$_2$As$_2$, x = 0 ~ 0.25) single crystals to tune the Fermi energy above the hole pocket. Our Hall measurements reveal that the isovalent Ca substitution decreases the hole carrier density by shrinking the lattice spacing, which is also confirmed by our first-principles calculations. We further find that both the temperature dependence of the magnetic susceptibility with a local maximum at the Néel temperature and the topological Hall effect originating from the finite real-space spin chirality persist in the Ca-doped samples as observed in the pristine EuIn$_2$As$_2$, despite that the nonmagnetic Ca substitution decreases the effective moment and the Néel temperature. These results show that the Ca substitution tunes the Fermi energy while keeping the AFM magnetic structure, suggesting that the axion insulating state may be realized by further Ca substitution.

description: We have serendipitously identified the first lithium-rich giant star located close to the red giant branch bump in a globular cluster. Through intermediate-resolution FLAMES spectra we derived a lithium abundance of A(Li)=2.55 (assuming local thermodynamical equilibrium), which is extremely high considering the star's evolutionary stage. Kinematic and photometric analysis confirm the object as a member of the globular cluster NGC 362. This is the fourth Li-rich giant discovered in a globular cluster but the only one known to exist at a luminosity close to the bump magnitude. The three previous detections are clearly more evolved, located close to, or beyond the tip of their red giant branch. Our observations are able to discard the accretion of planets/brown dwarfs, as well as an enhanced mass-loss mechanism as a formation channel for this rare object. Whilst the star sits just above the cluster bump luminosity, its temperature places it towards the blue side of the giant branch in the colour-magnitude diagram. We require further dedicated observations to unambiguously identify the star as a red giant: we are currently unable to confirm whether Li production has occurred at the bump of the luminosity function or if the star is on the pre zero-age horizontal branch. The latter scenario provides the opportunity for the star to have synthesised Li rapidly during the core helium flash or gradually during its red giant branch ascent via some extra mixing process.

description: The Atacama Large Aperture Submillimeter Telescope (AtLAST) aims to be the premier next generation large diameter (50-meter) single dish observatory capable of observations across the millimeter/sub-millimeter spectrum, from 30 to 950~GHz. The large primary mirror diameter, the 2-degree field of view and its large 4.7-meter focal surface give AtLAST a high throughput (aperture size times field of view) and grasp (throughput times spectral reach), with the ability to illuminate $>\mathcal{O}(10^7)$ detectors. The optical design concept for AtLAST consists of a numerically optimized two-mirror Ritchey-Chrétien system with an additional flat folding mirror, which enables a quick selection among its planned six instrument positions. We present the optical design concept and discuss the expected optical performance of AtLAST. We then present design concepts that can be implemented in the receiver and instrument optics to correct for astigmatism and mitigate the high degree of curvature of the focal surface in order to recover significant fractions of the geometric field of view at sub-millimeter wavelengths.

description: Machine learning has been proven to provide good performances on stress detection tasks using multi-modal sensor data from a smartwatch. Generally, machine learning techniques need a sufficient amount of data to train a robust model. Thus, we need to collect data from several users and send them to a central server to feed the algorithm. However, the uploaded data may contain sensitive information that can jeopardize the user’s privacy. Federated learning can tackle this challenge by enabling the model to be trained using data from all users without the user’s data leaving the user’s device. In this study, we implement federated learning-based stress detection and provide a comparative analysis between individual, centralized, and federated learning. The experiment was conducted on WESAD dataset by using Logistic Regression as the classifier. The experiment results show that in terms of accuracy, federated learning cannot reach the performance level of both individual and centralized learning. The individual learning strategy performs best with an average accuracy of 0.9998 and an average F1-measure of 0.9996.

description: The Su-Schrieffer-Heeger chain is a prototype example of a symmetry-protected topological insulator. Coupling it non-perturbatively to local thermal environments, either through the intercell or the intracell fermion tunneling elements, modifies the topological window. To understand this effect, we employ the recently developed reaction-coordinate polaron transform (RCPT) method, which allows treating system-bath interactions at arbitrary strengths. The effective system Hamiltonian, which is obtained via the RCPT, exposes the impact of the baths on the SSH chain through renormalization of tunneling elements and the generation of many-body interaction terms. By performing exact diagonalization and computing the ensemble geometric phase, a topological invariant applicable even to systems at finite temperature, we distinguish the trivial band insulator (BI) from the topological insulator (TI) phases. Furthermore, through the RCPT mapping, we are able to pinpoint the main mechanism behind the extension of the parameter space for the TI or the BI phases (depending on the coupling scheme, intracell or intercell), which is the bath-induced, dimerized, many-body interaction. We also study the effect of on-site staggered potentials on the SSH phase diagram, and discuss extensions of our method to higher dimensions.

description: We consider the electromagnetic field in the presence of polarizable point dipoles. In the corresponding effective Maxwell equation these dipoles are described by three dimensional delta function potentials. We review the approaches handling these: the selfadjoint extension, regularization/renormalisation and the zero range potential methods. Their close interrelations are discussed in detail and compared with the electrostatic approach which drops the contributions from the self fields. For a homogeneous two dimensional lattice of dipoles we write down the complete solutions, which allow, for example, for an easy numerical treatment of the scattering of the electromagnetic field on the lattice or for investigating plasmons. Using these formulas, we consider the limiting case of vanishing lattice spacing. For a scalar field and for the TE polarization of the electromagnetic field this transition is smooth and results in the results known from the continuous sheet. Especially for the TE polarization, we reproduce the results known from the hydrodynamic model describing a two dimensional electron gas. For the TM polarization, for polarizability parallel and perpendicular to the lattice, in both cases, the transition is singular. For the parallel polarizability this is surprising and different from the hydrodynamic model. For perpendicular polarizability this is what was known in literature. We also investigate the case when the transition is done with dipoles described by smeared delta function, i.e., keeping a regularization. Here, for TM polarization for parallel polarizability, when subsequently doing the limit of vanishing lattice spacing, we reproduce the result known from the hydrodynamic model. In case of perpendicular polarizability we need an additional renormalization to reproduce the result obtained previously by stepping back from the dipole approximation.

description: Large sharks are top predators in most coastal and marine ecosystems throughout the world, and evidence of their reduced prominence in marine ecosystems has been a serious concern for fisheries and ecosystem management. Unfortunately, quantitative data to document the extent, timing, and consequences of changes in shark populations are scarce, thwarting examination of long-term (decadal, century) trends, and reconstructions based on incomplete data sets have been the subject of debate. Absence of quantitative descriptors of past ecological conditions is a generic problem facing many fields of science but is particularly troublesome for fisheries scientists who must develop specific targets for restoration. We were able to use quantitative measurements of shark sizes collected annually and independently of any scientific survey by thousands of recreational fishermen over the last century to document decreases in the size of large sharks from the northern Gulf of Mexico. Based on records from fishing rodeos in three U.S. coastal states, the size (weight or length) of large sharks captured by fishermen decreased by 50-70% during the 20 years after the 1980s. The pattern is largely driven by reductions in the occurrence and sizes of Tiger Sharks Galeocerdo cuvier and Bull Sharks Carcharhinus leucas and to a lesser extent Hammerheads Sphyrna spp. This decrease occurred despite increasing fishing effort and advances in technology, but it is coincident with the capitalization of the U.S. commercial shark long-line fishery in the GOM.

description: We propose a hybrid quantum system consisting of a magnetic particle inductively coupled to two superconducting transmon qubits, where qubit-qubit interactions are mediated via magnons. We show that the system can be tuned into three different regimes of effective qubit-qubit interactions, namely a transverse ($XX + YY$), a longitudinal ($ZZ$) and a non-trivial $ZX$ interaction. In addition, we show that an enhanced coupling can be achieved by employing an ellipsoidal magnet, carrying anisotropic magnetic fluctuations. We propose a scheme for realizing two-qubit gates, and simulate their performance under realistic experimental conditions. We find that iSWAP and CZ gates can be performed in this setup with an average fidelity $\gtrsim 99 \% $ , while an iCNOT gate can be applied with an average fidelity $\gtrsim 88 \%$. Our proposed hybrid circuit architecture offers an alternative platform for realizing two-qubit gates between superconducting qubits and could be employed for constructing qubit networks using magnons as mediators.

description: Geochemical signatures of early life stages are increasingly used to study population connectivity. This approach utilizes spatial variability in chemical signatures to predict natal or nursery origins of post-dispersal individuals by comparison with a chemical reference atlas created from individuals of known origin. To examine the relative importance of spatial, temporal, and species variation in elemental signatures, we synthesized the chemical information of otoliths, larval shells, and whole larvae from studies that employed natural geochemical signatures in San Diego County, USA between 1997 and 2009. We compared 8 elements analyzed from 4 bivalve species, 2 larval or juvenile fishes, and Stage 1 crab zoeae. Across all species, different sets of elements best discriminated among open-coast sites or within or among bays and lagoons. In mytilid mussels, which had the most complete record, all 8 elements were more variable over time than space at the site level, highlighting the need to resample the reference atlas during each study. More coarsely, however, bay and lagoon taxa maintained distinct chemical signatures both from each other and from those on the open coast, despite interannual variability. Spatially identifiable signatures for all species were likely imparted by a combination of pollution in bays and export to adjacent coastlines (copper, lead), a heterogeneous distribution of land-sourced elements (manganese, cobalt, uranium), and incorporation that may vary in response to temperature (barium, manganese, strontium) and salinity (7 elements). These results identify important elements for larval tracking of additional species depending on habitat and life history; however, source population signatures appear species-specific.

description: Con la prima Rivoluzione verde ispirata al paradigma della modernizzazione agricola, la cooperazione tradizionale Nord-Sud esportò nel mondo il modello dell’agricoltura industriale, incentrato su monocolture per l’esportazione e con forti impatti socio-ecologici. Le nuove Rivoluzioni verdi propongono pratiche discorsive legate all’“intensificazione sostenibile” che combinano crescita economica e tutela ambientale attraverso una visione tecnocratica. Tale approccio non privo di contraddizioni è alla base di convergenze tra la cooperazione Nord-Sud e la cooperazione Sud-Sud, laddove il caso della cooperazione agricola Cina-Africa è emblematico. Dal 2006, i Centri di dimostrazione tecnologici dell’agricoltura (ATDC) sono la principale modalità di assistenza agricola estera offerta dalla Cina in oltre 25 paesi africani. Gli ATDC sono radicati nella logica della modernizzazione dell'agricoltura africana, con un ruolo di primo piano del capitale privato e statale e delle aziende cinesi nel trasferimento tecnologico. Tali Centri sono rappresentativi per riflettere sull'espansione della logica della modernizzazione agricola, nonostante il suo passato fallimentare, al di là delle dicotomie Nord/Sud.

description: The t0.technology Control and Readout System (CRS) is a modular microwave control and readout system for mm-wave and radio astronomy, THz imaging, noise radar, and superconducting qubit control. The configuration discussed in this work implements firmware for readout of microwave Kinetic Inductance Detector (KID) arrays. The CRS can operate 4,096 KIDs over 2.5 GHz of complex bandwidth between 0-10 GHz, typically allocated across four independent RF chains at 1,024x multiplexing and 625 MHz of complex bandwidth each. Every CRS can operate as a standalone unit or collectively within one or more backplane-enabled subracks that distribute power, clocking, and synchronization, scaling to an arbitrary number of channels. Each fully populated subrack supports arrays of more than 65,000 KIDs. The signal processing and control software supports recent innovations in multi-probe measurements and dynamic feedback modes, which are described in (Rouble et al. 2024). The CRS has recently been selected as the new baseline readout system for the proposed South Pole Telescope instrument, SPT-3G+. We present the hardware design, firmware capabilities, open-source control and data acquisition software, and the first laboratory characterization measurements.

description: Relativistic jets in active galactic nuclei represent one of the most powerful phenomena in the Universe. They form in the surroundings of the supermassive black holes as a by-product of accretion onto the central black hole in active galaxies. The flow in the jets propagates at velocities close to the speed of light. The distance between the first part of the jet that is visible in radio images (core) and the black hole is still a matter of debate. Only very-long-baseline interferometry observations resolve the innermost compact regions of the radio jet. Those can access the jet base, and combining data at different wavelenghts, address the physical parameters of the outflow from its emission. We have performed an accurate analysis of the frequency-dependent shift of the VLBI core location for a multi-wavelength set of images of the blazar CTA 102 including data from 6 cm down to 3 mm. The measure of the position of the central black hole, with mass $\sim 10^{8.93}\,M_\odot$, in the blazar CTA 102 reveals a distance of $\sim 8\times10^4$ gravitational radii to the 86 GHz core, in agreement with similar measures obtained for other blazars and distant radio galaxies, and in contrast with recent results for the case of nearby radio galaxies, which show distances between the black hole and the radio core that can be two orders of magnitude smaller.

description: Presupposto che la crescita dei contesti urbani è oggi fortemente insostenibile, le città dell’Africa sub-sahariana si interfacciano anche con una persistente scarsità di beni alimentari. Tale insufficienza è dettata primariamente da una governance del cibo pressoché assente nella quasi totalità delle città africane. Infatti, sebbene esistano alcuni centri urbani che hanno strutturato basilari Urban Food Policy atte a migliorare il sistema-cibo locale, soprattutto nell’ambito del MUFPP, la grande maggioranza delle città non prevede alcuna strategia in ambito di cibo. Tra le altre, anche Addis Abeba in Etiopia vive una sistemica insufficienza alimentare, ma non dispone di alcuno strumento di governance efficace; questo scritto presenta i primi esiti di una ricerca sul campo volta a determinare i tempi e i modi con cui la città intende realizzare una Urban Food Policy.

description: We consider non-relativistic curved geometries and argue that the background structure should be generalized from that considered in previous works. In this approach the derivative operator is defined by a Galilean spin connection valued in the Lie algebra of the Galilean group. This includes the usual spin connection plus an additional "boost connection" which parameterizes the freedom in the derivative operator not fixed by torsion or metric compatibility. As an example we write down the most general theory of dissipative fluids consistent with the second law in curved non-relativistic geometries and find significant differences in the allowed transport coefficients from those found previously. Kubo formulas for all response coefficients are presented. Our approach also immediately generalizes to systems with independent mass and charge currents as would arise in multicomponent fluids. Along the way we also discuss how to write general locally Galilean invariant non-relativistic actions for multiple particle species at any order in derivatives. A detailed review of the geometry and its relation to non-relativistic limits may be found in a companion paper [arXiv:1503.02682].

title: An investigation of factors influencing the student experience at university
Creators: name: Miles, Paula Jean
Publisher: name: University of St Andrews

description: University students are increasingly considered ‘consumers’, while universities are viewed as ‘service providers’. It is therefore imperative that higher education institutions explore and better understand factors influencing the student experience. This thesis investigates the impact that three elements of the university environment have on the student experience. Firstly, student and staff views of good academic practice were examined. Participants rated scenarios representing four areas of academic practice (aiding and abetting, multiple submission, contract cheating and plagiarism) as good practice, poor practice or misconduct. While scenarios at extreme ends of the academic practice continuum generated near-uniform responses, some scenarios lacked consensus between student and staff. The most contentious areas of academic practice were those involving help from peers. Disparity in opinions highlights the need for greater analysis and education to reach a shared understanding of academic practice across the university. Secondly, well-being levels of first year undergraduates were measured across an academic year to identify periods when students might benefit from additional support. Well-being was poorer at the end, compared to the beginning, of the academic season. In addition, students who completed high school in North America experienced poorer well-being compared to their UK and European peers. Finally the effectiveness of traditional and interactive teaching approaches were recorded following both teaching styles. This held true for experienced and novice teachers. Irrespective of teaching style, female students were less satisfied with sessions and less confident when completing final statistical analyses compared to males. Overall, this work has advanced understanding of how all three keys factors influence the student experience and has highlighted areas where improvements can be made. Importantly, this study demonstrates methodologies for conducting and scientifically rigorous research within an educational setting.
Cosmological constraints from the redshift dependence of the Alcock-Paczynski test and volume effect: galaxy two-point correlation function

description: We propose a method using the redshift dependence of the Alcock-Paczynski (AP) test and volume effect to measure the cosmic expansion history. The galaxy two-point correlation function as a function of angle, $ξ(μ)$, is measured at different redshifts. Assuming an incorrect cosmological model to convert galaxy redshifts to distances, the shape of $ξ(μ)$ appears anisotropic due to the AP effect, and the amplitude shifted by the change in comoving volume. Due to the redshift dependence of the AP and volume effect, both the shape and amplitude of $ξ(μ)$ exhibit redshift dependence. Similar to Li et.al (2014), we find the redshift-space distortions (RSD) caused by galaxy peculiar velocities, although significantly distorts $ξ(μ)$, exhibit much less redshift evolution compared to the AP and volume effects. By focusing on the redshift dependence of $ξ(μ)$, we can correctly recover the cosmological parameters despite the contamination of RSD. The method is tested by using the Horizon Run 3 N-body simulation, from which we made a series of $1/8$-sky mock surveys having 8 million physically self-bound halos and sampled to have roughly a uniform number density in $z=0-1.5$. We find the AP effect results in tight, unbiased constraints on the density parameter and dark energy equation of state, with 68.3% CL intervals $δΩ_m\sim0.03$ and $δw\sim0.1$, and the volume effect leads to much tighter constraints of $δΩ_m\sim0.007$ and $δw\sim0.035$.

description: We propose a way of including the next-to-leading (NLO) order spin-spin coupling into an effective-one-body (EOB) Hamiltonian. This work extends [S. Balmelli and P. Jetzer, Phys. Rev. D 87, 124036 (2013)], which is restricted to the case of equatorial orbits and aligned spins, to general orbits with arbitrary spin orientations. This is done applying appropriate canonical phase-space transformations to the NLO spin-spin Hamiltonian in Arnowitt-Deser-Misner (ADM) coordinates, and systematically adding "effectiv" quantities at NLO to all spin-squared terms appearing in the EOB Hamiltonian. As required by consistency, the introduced quantities reduce to zero in the test- mass limit. We expose the result both in a general gauge and in a gauge-fixed form. The last is chosen such as to minimize the number of new coefficients that have to be inserted into the effective spin squared. As a result, the 25 parameters that describe the ADM NLO spin-spin dynamics get condensed into only 12 EOB terms.

description: Rolling bearings face different damaging effects: Besides mechanical effects, current-induced bearing damage occurs in electrical drive systems. Therefore, it is of increasing interest to understand the differences leading to known electrical damage patterns. It is of utmost importance not to consider the harmful current passage in the machine element as an isolated phenomenon but to take into account the whole drive system consisting of the machine elements, the electric motor and the connected power electronics. This publication works toward providing an overview of the state-of-the-art of research regarding electrical bearing currents.

description: We investigate the abilities of a representative set of Large language Models (LLMs) to reason about cardinal directions (CDs). To do so, we create two datasets: the first, co-created with ChatGPT, focuses largely on recall of world knowledge about CDs; the second is generated from a set of templates, comprehensively testing an LLM's ability to determine the correct CD given a particular scenario. The templates allow for a number of degrees of variation such as means of locomotion of the agent involved, and whether set in the first , second or third person. Even with a temperature setting of zero, Our experiments show that although LLMs are able to perform well in the simpler dataset, in the second more complex dataset no LLM is able to reliably determine the correct CD, even with a temperature setting of zero.

description: The use of geochemical tags in calcified structures of fish and invertebrates is an exciting tool for investigating larval population connectivity. Tag evaluation over relatively short intervals (weeks) may detect environmental and ecological variability at a temporal scale highly relevant to larval transport and settlement. We collected newly settled mussels (Mytilus californianus and M. galloprovincialis) weekly during winter/spring of 2002 along the coast of San Diego, CA, USA, at sites on the exposed coast (SIO) and in a protected coastal bay (HI), to investigate temporal patterns of geochemical tags in mussel shells. Analyses of post-settlement shell via LA-ICP-MS revealed statistically significant temporal variability for all elements we examined (Mg, Mn, Cu, Sr, Cd, Ba, Pb and U). Despite this, our ability to distinguish multielemental signatures between sites was largely conserved. Throughout our 13-week study, SIO and HI mussels could be chemically distinguished from one another in 78-87% of all cases. Settlement varied between 2 and 27 settlers gram-byssus-1week-1 at SIO and HI, and both sites were characterized by 2-3weeks with "high" settlement. Geochemical tags recorded in early larval shell of newly settled mussels differed between "high" and "low" settlement weeks at both sites (MANOVA), driven by Mg and Sr at SIO (p=0.013) and Sr, Cd, Ba and Pb at HI (p<0.001). These data imply that shifts in larval sources or transport corridors were responsible for observed settlement variation, rather than increased larval production. In particular, increased settlement at HI was observed concurrent with the appearance of geochemical tags (e.g., elevated Cd), suggesting that those larvae were retained in upwelled water near the mouth of the bay. Such shifts may reflect short-term changes in connectivity among sites due to altered transport corridors, and influence the demography of local populations.

description: This thesis explores the Australian experience of inherited and acquired bleeding disorders. Patients with congenital and acquired bleeding disorders have their care managed by individual haemophilia treatment centres, all of whom report complications on the Australian Bleeding Disorders Registry (ABDR). There were several aspects of care of these patients examined including the complications of intravenous treatments of inherited bleeding disorders, rare consequences of failing to treat as well as the treatment of acquired haemophilia A and novel therapies for severe haemophilia and safety around sport. The aim of this thesis was to address unmet needs within the inherited bleeding disorder community and ideally aid clinicians who treat these conditions with local, clinically relevant data and studies.

description: The interplay of symmetry and topological order leads to a variety of distinct phases of matter, the Symmetry Enriched Topological (SET) phases. Here we discuss physical observables that distinguish different SETs in the context of Z$_2$ quantum spin liquids with SU(2) spin rotation invariance. We focus on the cylinder geometry, and show that ground state quantum numbers for different topological sectors are robust invariants which can be used to identify the SET phase. More generally these invariants are related to 1D symmetry protected topological phases when viewing the cylinder geometry as a 1D spin chain. In particular we show that the Kagome spin liquid SET can be determined by measurements on one ground state, by wrapping the Kagome in a few different ways on the cylinder. In addition to guiding numerical studies, this approach provides a transparent way to connect bosonic and fermionic mean field theories of spin liquids. When fusing quasiparticles, it correctly predicts nontrivial phase factors for combining their space group quantum numbers.

description: An increasingly common approach for examining the movement of fish involves elemental fingerprinting, which exploits variation in the chemical composition of otoliths induced by environmental gradients. We assessed the elemental signatures of recently deposited material in the otoliths of juvenile California halibut Paralichthys californicus collected from different zones along the main axis of coastal embayments of southern California, USA, and Baja California, Mexico. From these data, we determined if unique chemical signals within embayments allowed for the reconstruction of movement patterns over small scales. Juvenile halibut were collected during 3 years (2001 to 2003) along 2 segments of coastline, including 4 embayment and 3 exposed habitats. We also compared otolith chemistry from wild-caught and caged halibut in the Punta Banda Estuary, Baja California, Mexico, and Mission Bay, California, USA; within both locations, we observed increasing concentrations of Mn and Ba in the otoliths of wild-caught and caged juveniles collected farther within embayments. However, only in Punta Banda did we find strong congruence between otolith signals from wild-caught and caged individuals. Hence, we exploited the intra-embayment variability in otolith microchemistry to chart 2 forms of movement of juvenile halibut within Punta Banda. First, within-embayment movements of juvenile fish were examined over 2 mo. Over this timescale, 8 of 14 individuals had moved among embayment zones. Second, the contribution of different embayment zones to production of adult biomass was determined. The vast majority of juveniles (82 to 89 %, n = 27) that advanced to older age classes during 2002 and 2003 occupied the middle and outer zones of Punta Banda. Recognition of intra-embayment variability in otolith signals from southern and Baja California should allow for finer-scale analyses of habitat utilization, and more thorough examination of connectivity resulting from the ontogenetic migration of fish from juvenile to adult habitats.

description: Sustainable Development Goals (SDGs) are part of 2030 Agenda for Sustainable Development (SD) that aim to eradicate poverty, achieve economic prosperity, gender equality, ensure social well-being, promote sustainable management and use of natural resources, and protect the Earth’s natural ecosystems. However, the occurrence of human–wildlife conflict (HWC) may impair SDGs to be achieved in developing regions where people and wildlife cooccur frequently. Surprisingly, there are few studies which have examined how HWC impedes achievement of SDGs. This paucity of information hinders the formulation and implementation of appropriate policy actions to achieve SDGs. We explored how HWC impacts on the livelihoods of rural communities in Bhutan through SD lens. We used a mixed method research approach and interviewed a stratified-random sample of 96 farmers from four different regions of Bhutan. Wildlife impacts are multidimensional and can inhibit achievement of several SDGs. All interviewees suffered crop and livestock depredations with substantial economic losses. These losses were higher for female-headed households and those with low asset holding, compounding their vulnerability. Among the HWC adaptation measures, adopted guarding, vigilant livestock herding, and electric fences were perceived effective but were predominantly applied by households in high asset class. Policy actions should focus on female-headed households and those families with lower asset category to reduce negative impacts of human wildlife interactions.

description: We investigated the nursery role of four coastal ecosystems for the California halibut (Paralichthys californicus) using the following metrics: (1) contribution in producing the fish that advance to older age classes, (2) connectivity of coastal systems resulting from migration of fish from juvenile to subadult habitats, and (3) effect of nursery habitat usage and availability on subadult population size, specifically evaluating the concentration hypothesis. Potential nurseries were grouped using a robust classification scheme that segregated exposed, bay, lagoon, and estuarine environments. Assignment of nursery origins for individual subadult fish via elemental fingerprinting indicated that exposed coasts, bays, lagoons, and estuaries contributed 31%, 65%, 1%, and 3% of advancing juvenile halibut during 2003, versus 49%, 33%, 16%, and 2% during 2004, respectively. These results were remarkably similar to "expected" nursery contributions derived from field surveys, suggesting that in this system juvenile distributions were a good indicator of unit-area productivity of juvenile habitats and that density-dependent mechanisms during the juvenile phase did not regulate recruitment pulses. Elemental fingerprinting also demonstrated that individuals egressing from bays did not migrate far from their nursery origins (<10 km), resulting in reduced connectivity along the 110-km study region over the timescale of approximately one generation. Consequently, we observed considerably higher subadult densities at sites near large bays, while populations distant from large bays appeared to be more influenced by nursery habitat limitation. Over large (∼100 km) scales, the location and availability of nursery habitat alternatives had significant effects on the population dynamics of an important member of the ichthyofaunal community of southern California.
