Remarks.
Previously recorded from multiple localities near the East African Coast and the Western Indian Ocean (Ribaut 1914; Bonato and Minelli 2010; Popovici et al. 2024), making natural dispersal a likely explanation for the presence of M. angusticeps in Aldabra. Presently examined specimens are morphologically indistinguishable from conspecifics recorded from the Seychelles and the Chagos Islands. Although not previously noted, the forcipular cerri were found to be absent in examined specimens (Fig. 11 B). In combination with other diagnostic characters (47 leg-bearing segments, conspicuous medial reduction in clypeal reticulation, large distal trochanteroprefemoral denticle and sternal sulcus not furcate), this allows for easy separation from other syntopic Mecistocephalus spp. within its range.

description: Under increasing scrutiny, many web companies now offer bespoke mechanisms allowing any third party to file complaints (e.g., requesting the de-listing of a URL from a search engine). While this self-regulation might be a valuable web governance tool, it places huge responsibility within the hands of these organisations that demands close examination. We present the first large-scale study of web complaints (over 1 billion URLs). We find a range of complainants, largely focused on copyright enforcement. Whereas the majority of organisations are occasional users of the complaint system, we find a number of bulk senders specialised in targeting specific types of domain. We identify a series of trends and patterns amongst both the domains and complainants. By inspecting the availability of the domains, we also observe that a sizeable portion go offline shortly after complaints are generated. This paper sheds critical light on how complaints are issued, who they pertain to and which domains go offline after complaints are issued.

description: We study the one-dimensional Bose-Hubbard model using the Density-Matrix Renormalization Group (DMRG).For the cases of on-site interactions and additional nearest-neighbor interactions the phase boundaries of the Mott-insulators and charge density wave phases are determined. We find a direct phase transition between the charge density wave phase and the superfluid phase, and no supersolid or normal phases. In the presence of nearest-neighbor interaction the charge density wave phase is completely surrounded by a region in which the effective interactions in the superfluid phase are repulsive. It is known from Luttinger liquid theory that a single impurity causes the system to be insulating if the effective interactions are repulsive, and that an even bigger region of the superfluid phase is driven into a Bose-glass phase by any finite quenched disorder. We determine the boundaries of both regions in the phase diagram. The ac-conductivity in the superfluid phase in the attractive and the repulsive region is calculated, and a big superfluid stiffness is found in the attractive as well as the repulsive region.

description: A Monte Carlo method for dynamics simulation of all-atom protein models is introduced, to reach long times not accessible to conventional molecular dynamics. The considered degrees of freedom are the dihedrals at C$_α$-atoms. Two Monte Carlo moves are used: single rotations about torsion axes, and cooperative rotations in windows of amide planes, changing the conformation globally and locally, respectively. For local moves Jacobians are used to obtain an unbiased distribution of dihedrals. A molecular dynamics energy function adapted to the protein model is employed. A polypeptide is folded into native-like structures by local but not by global moves.

description: The maintenance, repair and overhaul (MRO) processes of aircraft engines are dominated by a high proportion of manual work and subjective condition assessment of used parts. This leads to inefficiency due to additional, partially not required workload and high scrap rates. Further, there is a lack of knowledge about the effects of the respective repair measures on the performance of the parts. So far, there are no autonomous repair solutions that allow an optimal and individually tailored regeneration. In order to realize such a process, it is necessary to bring together the manufacturing, function-simulating and logistics-oriented disciplines in an integrated system. For this, data management along the process chain is an important success factor. In particular, the provision and linking of the data and data formats required for simulation and the production environment is of fundamental importance. This paper presents a data architecture that can serve as a framework for data integration within a representative process chain for regeneration.
Constraining the mass density of free-floating black holes using razor-thin lensing arcs

description: Strong lensing of active galactic nuclei in the radio can result in razor-thin arcs, with a thickness of less than a milli-arcsecond, if observed at the resolution achievable with very long baseline interferometry (VLBI). Such razor-thin arcs provide a unique window on the coarseness of the matter distribution between source and observer. In this paper, we investigate to what extent such razor-thin arcs can constrain the number density and mass function of `free-floating' black holes, defined as black holes that do not, or no longer, reside at the centre of a galaxy. These can be either primordial in origin or arise as by-products of the evolution of super-massive black holes in galactic nuclei. When sufficiently close to the line of sight, free-floating black holes cause kink-like distortions in the arcs, which are detectable by eye in the VLBI images as long as the black hole mass exceeds $\sim 1000$ Solar masses. Using a crude estimate for the detectability of such distortions, we analytically compute constraints on the matter density of free-floating black holes resulting from null-detections of distortions along a realistic, fiducial arc, and find them to be comparable to those from quasar milli-lensing. We also use predictions from a large hydrodynamical simulation for the demographics of free-floating black holes that are not primordial in origin, and show that their predicted mass density is roughly four orders of magnitude below the constraints achievable with a single razor-thin arc.

description: We show that cosmic-ray observations set a model-independent upper bound to the flux of high-energy, > 10^14 eV, neutrinos produced by photo-meson (or p-p) interactions in sources of size not much larger than the proton photo-meson (or pp) mean-free-path. The bound applies, in particular, to neutrino production by either AGN jets or GRBs. This upper limit is two orders of magnitude below the flux predicted in some popular AGN jet models, but is consistent with our predictions from GRB models. We discuss the implications of these results for future km^2 high-energy neutrino detectors.

description: For the successful production of high quality parts by selective laser melting, various process steps are required. Besides the SLM process itself, different pre- and rework steps are needed to produce a final component. Therefore, the first part of this paper presents a concept of a standardized process chain for carrying out the necessary planning and production procedures. For this purpose, the CAD-model is enriched with information regarding support structures, the desired surface quality and the position of tooling points. Since major steps in the reworking procedure are the removal of residual powder, the removal of support structures and the finishing operations for functional component surfaces, selected experimental results concerning these steps are presented in the second part of the paper. Based on the result, recommendations for the design of support structures are given.

description: Ghost-spins, 2-level spin-like variables with indefinite norm have been studied in previous work. Here we explore various $N$-level generalizations of ghost-spins. First we discuss a flavoured generalization comprising $N$ copies of the ghost-spin system, as well as certain ghost-spin chains which in the continuum limit lead to 2-dim $bc$-ghost CFTs with $O(N)$ flavour symmetry. Then we explore a symplectic generalization that involves antisymmetric inner products, and finally a ghost-spin system exhibiting $N$ irreducible levels. We also study entanglement properties. In all these cases, we show the existence of positive norm "correlated ghost-spin" states in two copies of ghost-spin ensembles obtained by entangling identical ghost-spins from each copy: these exhibit positive entanglement entropy.

Scaling and Scale Breaking in Polyelectrolyte

description: We consider the thermodynamics of a uniformly charged polyelectrolyte with harmonic bonds. For such a system there is at high temperatures an approximate scaling of global properties like the end-to-end distance and the interaction energy with the chain-length divided by the temperature. This scaling is broken at low temperatures by the ultraviolet divergence of the Coulomb potential. By introducing a renormalization of the strength of the nearest- neighbour interaction the scaling is restored, making possible an efficient blocking method for emulating very large polyelectrolytes using small systems. The high temperature behaviour is well reproduced by the analytical high-$T$ expansions even for fairly low temperatures and system sizes. In addition, results from low-$T$ expansions, where the coefficients have been computed numerically, are presented. These results approximate well the corresponding Monte Carlo results at realistic temperatures. A corresponding analysis of screened chains is performed. The situation here is complicated by the appearance of an additional parameter, the screening length. A window is found in parameter space, where scaling holds for the end-to-end distance. This window corresponds to situations where the range of the potential interpolates between the bond length and the size of the chain. This scaling behaviour, which is verified by Monte Carlo results, is consistent with Flory scaling. Also for the screened chain a blocking approach can be devised, that performs well for low temperatures, whereas the low-$T$ expansion is inaccurate at realistic temperatures.

description: Numerical investigations have been made of responses of a Hodgkin-Huxley (HH) neuron to spike-train inputs whose interspike interval (ISI) is modulated by deterministic, semi-deterministic (chaotic) and stochastic signals. As deterministic one, we adopt inputs with the time-independent ISI and with time-dependent ISI modulated by sinusoidal signal. The Rössler and Lorentz models are adopted for chaotic modulations of ISI. Stochastic ISI inputs with the Gamma distribution are employed. It is shown that distribution of output ISI data depends not only on the mean of ISIs of spike-train inputs but also on their fluctuations. The distinction of responses to the three kinds of inputs can be made by return maps of input and output ISIs, but not by their histograms. The relation between the variations of input and output ISIs is shown to be different from that of the integrate and fire (IF) model because of the refractory period in the HH neuron.

Truncation of lattice fractional quantum Hall Hamiltonians derived from conformal field theory

description: Conformal field theory has recently been applied to derive few-body Hamiltonians whose ground states are lattice versions of fractional quantum Hall states. The exact lattice models involve interactions over long distances, which is difficult to realize in experiments. It seems, however, that such long-range interactions should not be necessary, as the correlations decay exponentially in the bulk. This poses the question, whether the Hamiltonians can be truncated to contain only local interactions without changing the physics of the ground state. Previous studies have in a couple of cases with particularly much symmetry obtained such local Hamiltonians by keeping only a few local terms and numerically optimizing the coefficients. Here, we investigate a different strategy to construct truncated Hamiltonians, which does not rely on optimization, and which can be applied independent of the choice of lattice. We test the approach on two models with bosonic Laughlin-like ground states with filling factor $1/2$ and $1/4$, respectively. We first investigate how the coupling strengths in the exact Hamiltonians depend on distance, and then we study the truncated models. For the case of $1/2$ filling, we find that the truncated model with truncation radius $\sqrt{2}$ lattice constants on the square lattice and $1$ lattice constant on the triangular lattice has an approximate twofold ground state degeneracy on the torus, and the overlap per site between these states and the states constructed from conformal field theory is higher than $0.99$ for the lattices considered. For the model at $1/4$ filling, our results give some hints that a truncation radius of $\sqrt{5}$ on the square lattice and $\sqrt{7}$ on the triangular lattice might be enough, but the finite size effects are too large to judge whether the topology is, indeed, present in the thermodynamic limit.

Remarks.
Originally described from Mauritius (Verhoeff, 1939), M. lohmanderi has been found on other Western Indian Ocean Islands (Bonato and Minelli 2010; Popovici et al. 2024). Similarly to M. angusticeps (Fig. 11 B), examined specimens lack forcipular cerri (Fig. 11 A). Presently examined specimens are most similar to M. lohmanderi specimens collected from the Diego Garcia atoll (Popovici et al. 2024). Adults (female 34 mm body length, male 34 mm body length) in the Aldabra sample lack dark subcutaneous pigment patches and maintain the characteristic clypeal setation pattern described in M. lohmanderi from other localities (Bonato and Minelli 2010; Popovici et al. 2024). Similarly, specimens assigned to M. insularis described from Socotra (Lewis and Wranik 1990) match all diagnostic characters outlined for M. lohmanderi, and can be referred to this taxon, thus extending its range to island localities in the Northwestern Indian Ocean.
Records of large adult specimens (70–91 mm) assigned to Mecistocephalus insularis from the Arabian Peninsula (Lewis 1996) are fully consistent with the revised description of Mecistocephalus glabridorsalis Attems, 1900 from the Seychelles (Bonato and Minelli 2010) and are almost certainly misidentified M. glabridorsalis. In particular, the clypeal morphology illustrated for specimens from Saudi Arabia shares the presence of a small non-areolate insula anterior to the plagulae with specimens from the Seychelles and the arrangement of setae in a transverse line on the areolate part of the clypeus. This morphology has hitherto only been recorded in M. glabridorsalis and M. punctifrons Newport, 1843 (Bonato and Minelli 2004), casting further doubt on the true identity and distribution of M. insularis. Insufficient data on morphological variability in M. lohmanderi and the uncertain status of M. insularis records from past literature prevent further inferences on the taxonomic validity and relationships between these species.

description: This article presents our steps to integrate complex and partly unstructured medical data into a clinical research database with subsequent decision support. Our main application is an integrated faceted search tool, accompanied by the visualisation of results of automatic information extraction from textual documents. We describe the details of our technical architecture (open-source tools), to be replicated at other universities, research institutes, or hospitals. Our exemplary use cases are nephrology and mammography. The software was first developed in the nephrology domain and then adapted to the mammography use case. We report on these case studies, illustrating how the application can be used by a clinician and which questions can be answered. We show that our architecture and the employed software modules are suitable for both areas of application with a limited amount of adaptations. For example, in nephrology we try to answer questions about the temporal characteristics of event sequences to gain significant insight from the data for cohort selection. We present a versatile time-line tool that enables the user to explore relations between a multitude of diagnosis and laboratory values.

description: Moduli fields, a natural prediction of any supergravity and superstring-inspired supersymmetry theory, may lead to a prolonged period of matter domination in the early Universe. This can be observationally viable provided the moduli decay early enough to avoid harming nucleosynthesis. If primordial black holes form, they would be expected to do so before or during this matter dominated era. We examine the extent to which the standard primordial black hole constraints are weakened in such a cosmology. Permitted mass fractions of black holes at formation are of order $10^{-8}$, rather than the usual $10^{-20}$ or so. If the black holes form from density perturbations with a power-law spectrum, its spectral index is limited to $n \lesssim 1.3$, rather than the $n \lesssim 1.25$ obtained in the standard cosmology.

description: Structure factors for Cax/2AlxSi1-xO2 glasses (x=0,0.25,0.5,0.67) extended to a wave vector of magnitude Q= 40 1/A have been obtained by high-energy x-ray diffraction. For the first time, it is possible to resolve the contributions of Si-O, Al-O and Ca-O coordination polyhedra to the experimental atomic pair distribution functions (PDF). It has been found that both Si and Al are four-fold coordinated and so participate in a continuous tetrahedral network at low values of x. The number of network breaking defects in the form of non-bridging oxygens (NBO's) increases slowly with x until x=0.5 (NBO's ~ 10% at x=0.5). By x=0.67 the network breaking defects become significant as evidenced by the significant drop in the average coordination number of Si. By contrast, Al-O tetrahedra remain free of NBO's and fully integrated in the Al/Si-O network for all values of x. Calcium maintains a rather uniform coordination sphere of approximately 5 oxygen atoms for all values of x. The results suggest that not only Si/Al-O tetrahedra but Ca-O polyhedra, too, play a role in determining the glassy structure.

description: At a large university library, RFID tags were incorporated into all materials, in anticipation of using RFID as multi-purpose tool for circulation, theft protection, and stacks management. The incorporation of these tags as substitutes for barcodes and security tape worked smoothly, as the circulation workflows were adapted to include newly necessary tasks such as applying and re-writing the tags themselves. However, the second phase of this project created unforeseen challenges, some of which remain problematic and unsolved. Despite being hailed as the up-and-coming, all-encompassing solution for library circulation, security, and stacks management, the implementation of RFID technology into the daily workflows of stacks management and inventory projects required a great deal of technical expertise and support, coming as a surprise for the library team. In this talk, the project’s attempted timeline and workflow will be described and evaluated. Strategies that we could have adopted for anticipating and troubleshooting these scenarios will be discussed, as well as tactics for building an RFID implementation team, skills, and useful tools.

description: Neural networks are extremely versatile tools, as evidenced by their widespread adoption into many ﬁelds in the sciences and beyond, including the geosciences. In seismology neural networks have been primarily used to automatically detect and discriminate seismic signals within time-series data, as well as provide location estimates for their sources. However, as neural network research has signiﬁcantly progressed over the past three decades, so too have its applications in seismology. Such applications now include earthquake early warning systems based on smartphone data collected from large numbers of users, the prediction of peak ground acceleration from earthquake source parameters, the eﬃcient computation of synthetic seismograms, providing probabilistic estimates of solutions to geophysical inverse problems, and many others. This thesis contains three components, each of which explore novel uses of neural networks in seismology. In the ﬁrst component, a previously established earthquake detection and location method is supplemented with a neural network in order to automate the detection process. The detection procedure is then applied to a large volume of seismic data. In addition to automating the detection process, the neural network removes the need for several user-deﬁned thresholds, subjective criteria otherwise necessary for the method. In the second component, a novel approach is developed for inverting seaﬂoor compliance data recorded by ocean-bottom seismometers for the shallow shear-wave velocity structure of oceanic tectonic plates. The approach makes use of mixture density networks, a type of neural network designed to provide probabilistic estimates of solutions to inverse problems, something that standard neural networks are incapable of. In the ﬁnal component of this thesis, the mixture density network approach to compliance inversion is applied to a group of ocean-bottom seismometers deployed along the continental shelf of the Cascadia Subduction Zone in order to investigate shelf sediment properties.

description: Diffusion properties of a self-avoiding polymer embedded in regularly distributed obstacles with spacing a=20 and confined in two dimensions is studied numerically using the extended bond fluctuation method which we have developed recently. We have observed for the first time to our knowledge, that the mean square displacement of a center monomer $ϕ_{M/2}(t)$ exhibits four dynamical regimes, i.e., $ϕ_{M/2}(t) \sim t^{ν_m}$ with $ν_m\sim 0.6$, 3/8, 3/4, and 1 from the shortest to longest time regimes. The exponents in the second and third regimes are well described by segmental diffusion in the ``self-avoiding tube''. In the fourth (free diffusion) regime, we have numerically confirmed the relation between the reptation time $τ_d$ and the number of segments $M, τ_d\propto M^3$.

Response to Eisenstein and Bunn's Null Hypothesis Comment on Cosmological Birefringence

description: Eisenstein and Bunn have widely circulated a Comment (astro-ph/9704247) suggesting a non-standard null hypothesis in a test for cosmological birefringence. The Comment misrepresents the procedure used by Nodland and Ralston (B. Nodland and J. P. Ralston, Phys. Rev. Lett. 78, 3043 (1997); astro-ph/9704196) and lacks statistical basis; no calculations were reported, but sweeping conclusions were drawn from eyeballing a single scatter plot. The results of the suggested procedure range from an underestimate of the statistical significance of well-correlated data, to a failure of detecting a perfect correlation in the limit of strong cuts. We verified these faults by performing the actual calculation which EB suggested, but neglected to carry out themselves. Furthermore, the calculation showed that the original correlation remains statistically significant, with the lego-plot of 1/P versus s showing a persistent bump, and the anisotropy direction s remaining in the same direction as previously reported.

description: In this paper we study a random matrix model with the chiral and flavor structure of the QCD Dirac operator and a temperature dependence given by the lowest Matsubara frequency. Using the supersymmetric method for random matrix theory, we obtain an exact, analytic expression for the average spectral density. In the large-n limit, the spectral density can be obtained from the solution to a cubic equation. This spectral density is non-zero in the vicinity of eigenvalue zero only for temperatures below the critical temperature of this model. Our main result is the demonstration that the microscopic limit of the spectral density is independent of temperature up to the critical temperature. This is due to a number of `miraculous' cancellations. This result provides strong support for the conjecture that the microscopic spectral density is universal. In our derivation, we emphasize the symmetries of the partition function and show that this universal behavior is closely related to the existence of an invariant saddle-point manifold.

description: Abstract
Parthenium weed (Parthenium hysterophorus L.), is one of the top alien invasive weed species in more than 40 countries, including Ethiopia. It infests several crops and causes significant yield losses, the extent of which depends, among others, on the density of weed and characteristics of crop species. Therefore, the objective of this study was to evaluate the effect of Parthenium (Parthenium hysterophorus L.) weed density on vegetative growth and grain yield of teff (Eragrostis tef Zucc. Trotter) using field experiment. Factorial combination of two traditional teff landraces namely Nech and Seregegna; and three levels of weed density (0, 5% and 10%) were used in the study.
T=0 Partition Functions for Potts Antiferromagnets on Lattice Strips with Fully Periodic Boundary Conditions

description: We present exact calculations of the zero-temperature partition function for the $q$-state Potts antiferromagnet (equivalently, the chromatic polynomial) for families of arbitrarily long strip graphs of the square and triangular lattices with width $L_y=4$ and boundary conditions that are doubly periodic or doubly periodic with reversed orientation (i.e. of torus or Klein bottle type). These boundary conditions have the advantage of removing edge effects. In the limit of infinite length, we calculate the exponent of the entropy, $W(q)$ and determine the continuous locus ${\cal B}$ where it is singular. We also give results for toroidal strips involving ``crossing subgraphs''; these make possible a unified treatment of torus and Klein bottle boundary conditions and enable us to prove that for a given strip, the locus ${\cal B}$ is the same for these boundary conditions.

description: The chromopolarizability of a quarknonium describes the quarknonium's interaction with soft gluonic fields and can be measured in the heavy quarkonium decays. Within the framework of dispersion theory which consider the $ππ$ final state interaction (FSI) model-independently, we analyze the transition $ψ^\prime\to J/ψπ^+π^-$ and obtain the chromopolarizability $α_{ψ^\prime ψ}$ and the parameter $κ$. It is found that the $ππ$ FSI plays an important role in extracting the chromopolarizability from the experimental data. The obtained chromopolarizability with the FSI is reduced to about 1/2 of that without the FSI. With the FSI, we determine the chromopolarizability $|α_{ψ^\primeψ}|=(1.44\pm 0.02)$ GeV$^{-3}$ and the parameter $κ=0.139\pm 0.005.$ Our results could be useful in studying the interactions of charmonium with light hadrons.

description: We perform a fit to the full data set corresponding to 33.3 kt-yr of data of the Super-Kamiokande experiment as well as to all other experiments in order to compare the two most likely solutions to the atmospheric neutrino anomaly in terms of oscillations in the $ν_μ\to ν_τ$ and $ν_μ\to ν_s$ channels. Using state-of-the-art atmospheric neutrino fluxes we have determined the allowed regions of oscillation parameters for both channels. We find that the $Δm^2$ values for the active-sterile oscillations (both for positive and negative $Δm^2$) are higher than for the $ν_μ\to ν_τ$ case, and that the increased Super-Kamiokande sample slightly favours $ν_μ\to ν_τ$ oscillations over oscillations into a sterile species $ν_s$, $ν_μ\to ν_s$, and disfavours $ν_μ\to ν_e$. We also give the zenith angle distributions predicted for the best fit points in each of the possible oscillation channels. Finally we compare our determinations of the atmospheric neutrino oscillation parameters with the expected sensitivities of future long-baseline experiments K2K, MINOS, ICARUS, OPERA and NOE.

description: A given field theory action determines a set of field equations but other actions may yield equivalent field equations; if so they are on-shell equivalent. They may also be off-shell equivalent, being related by the elimination of auxiliary fields or by local field redefinitions, but this is not guaranteed, as we demonstrate by consideration of the linearized limit of 3D massive gravity models. Failure to appreciate this subtlety has led to incorrect conclusions in recent studies of the "Minimal Massive Gravity" model.
