description: Nonzero-sum stochastic differential games with impulse controls offer a realistic and far-reaching modelling framework for applications within finance, energy markets, and other areas, but the difficulty in solving such problems has hindered their proliferation. Semi-analytical approaches make strong assumptions pertaining to very particular cases. To the author's best knowledge, the only numerical method in the literature is the heuristic one we put forward to solve an underlying system of quasi-variational inequalities. Focusing on symmetric games, this paper presents a simpler, more precise and efficient fixed-point policy-iteration-type algorithm which removes the strong dependence on the initial guess and the relaxation scheme of the previous method. A rigorous convergence analysis is undertaken with natural assumptions on the players strategies, which admit graph-theoretic interpretations in the context of weakly chained diagonally dominant matrices. A novel provably convergent single-player impulse control solver is also provided. The main algorithm is used to compute with high precision equilibrium payoffs and Nash equilibria of otherwise very challenging problems, and even some which go beyond the scope of the currently available theory.

description: Using a classical and quantum mechanical analysis, we show that the magnetic field gives rise to dynamical symmetries of a three-dimensional axially symmetric two-electron quantum dot with a parabolic confinement. These symmetries manifest themselves as near-degeneracies in the quantum spectrum at specific values of the magnetic field and are robust at any strength of the electron-electron interaction.

description: Farm management is a series of complex processes incorporating a variety of dynamic factors, including biological production systems, resource allocation and management, and the management of increasingly complex financial and economic systems. Farm managers are constantly required to prioritize and allocate management effort and attention amongst these factors and evaluate tradeoffs. This analysis elicited from commercial producers the relative ranking of five critical farm management focus areas, namely, managing production; managing land, equipment, and facilities; controlling costs; managing output prices; and managing people. Out of a total of 2,247 commercial farms in this study, the largest mean shares of importance were placed on controlling costs (28.6%) and managing production (27.3%). Producers, on average, emphasized the management areas of controlling costs and managing production, relative to managing land, equipment, and facilities; managing people; and managing output prices, for farm success. Correlations between the farm management focus areas studied were estimated from producer-specific share of importance estimates resulting from a random parameters logit model; the strongest correlation observed was the negative relationship between managing production and controlling costs. Implications for self-identified success factors, or critical areas of management focus, of commercial farms are far reaching, potentially influencing sales, marketing, and decision support for these operations, as well as driving research and programmatic focus to provide relevant information to these producers moving forward.

Annenkova

description: Annenkova n. gen.
 Type species: Flabelligera mastigophora Annenkova, 1952.
 Diagnosis. Body blunt anteriorly, tapering posteriorly. Tunic thick, fragile, soft, including mostly individual papillae, papillae not forming groups. Cephalic cage chaetae long, mostly exposed. Notochaetae long, multiarticulated capillaries with short articles basally, medium-sized medially, long distally; neurohooks usually one per ramus, multiarticulated in anterior chaetigers, oligoarticulate in median chaetigers, anchylosed in posterior chaetigers; crest thin, apparently articulated, tapering into a variably curved mucro. Free-living.
 Etymology. The genus is named after the late Nadezhda Pavlovna Annenkova-Chlopina, in recognition of her many publications on Russian polychaetes, and especially for her publications on flabelligerids. Her telegraphic style was combined with a good eye for recognizing diagnostic features, a combination that is regretfully fading out in some current taxonomical studies.
 Remarks. Annenkova n. gen. differs from Flabelligera Sars, and from Flabegraviera n. gen., by having a thin, loosely arranged tunic and especially because it has a special type of neurohook with a long, tapering, thin crest that looks articulated. The tunic might be eroded by dredging or during sample sieving. However, the tapering thin crest in the neurohooks is a unique feature and a true autapomorphy for the group. The apparently articulated structure is rather a difference in the transparency of the inner core, being completely hyaline distally and slightly more fibrous subdistally, but there is no articulation.
 Distribution. Currently, the genus includes only the type species and is restricted to the Okhotsk, Chukchi and Bering seas.

description: Cooking habits and product quality can impact consumer’s in-grocery and at-home food decisions. On February 12, 2016, a survey was launched; data collection concluded two weeks later for a total sample of 1,265 respondents. Household demographic information was collected, as well as information about cooking habits, where respondents learned healthy eating, and acceptance of damaged food items. Males made up 48% of the sample, with those aged 45 to 64 years old representing the largest age group (38%) in the sample. In terms of method of learning healthy eating, learning from family was selected by 56% of the sample. A majority of the sample was willing to accept or buy food past the sale by date (61%), accept or buy damaged produce (53%), and accept or buy dented canned or boxed items (77%).

When the coupling field is non-adiabatically switched on using a Pockels cell, transient probe gain without population inversion is obtained in the presence of uncoupled absorptions. Our results are supported by three-state computations.

description: Five-dimensional braneworld constructions in anti-de Sitter space naturally lead to dark sector scenarios in which parts of the dark sector vanish at high 4d momentum or temperature. In the language of modified gravity, such feature implies a new mechanism for hiding light scalars, as well as the possibility of UV-completing chameleon-like effective theories. In the language of dark matter phenomenology, the high-energy behaviour of the mediator sector changes dark matter observational complementarity. A multitude of signatures---including exotic ones---are present from laboratory to cosmologic scales, including long-range forces with non-integer behaviour, periodic signals at colliders, `soft bombs' events well-known from conformal theories, as well as a dark phase transition and a typically small amount of dark radiation.

description: The Breakthrough Starshot project aims to send centimeter-sized, gram-scale "StarChip" probes to Alpha Centauri at a speed of $\sim0.2c$. On the other hand, Zhang \& Li recently proposed that trans-relativistic cameras may be sent to any direction to study astronomical objects and test special relativity. To conduct such "relativistic astronomy", one needs to solve the motion of the probe in flight. We solve the motion of the probe (including the moving direction and the velocity) by comparing the positions of three or more point sources observed in the Earth rest frame and in the probe's comoving frame. When the positions of enough point sources are taken into account, the motion of the probe can be solved with an error which is even smaller than the diffraction limit of the transrelativistic camera. After solving the motion, when the measurement of the position of an additional point source is introduced, one can use the data to test the light aberration effect in special relativity. The upper limit of the photon mass can be placed from the deviation of aberration to slightly lower than the energy of the photon, e.g. $\sim 1 \rm {eV}$.

 Material examined. None available.
 Diagnosis. Tunic transparent. Body brick-red. Neurohooks often in pairs, handle articles long; crests very long, width:length ratio 1:9.
 Remarks. Flabelligera buski (McIntosh, 1869), a rather poorly described species, resembles F. bophortica Annenkova-Chlopina, 1924 because both have neurohooks with long crests. They differ because in F. buski neuropodia have two neurohooks per ramus and their crests are very long (width:length ratio 1:9), whereas in F. bophortica most neuropodia have single neurohooks and the crests are shorter (width:length ratio 1:6(7)). On the other hand, according to Newbigin (1900:194), juveniles of F. diplochaitus have two hooks per rami, and since their hooks have typically long crests, F. buski might be more closely allied to this species (Haase 1915:174). This confusion might be resolved with more specimens of F.buski, especially adult ones, which should have fully developed neurochaetal numbers.
 The species has been regarded as juvenile F. affinis; even McIntosh repeatedly indicated this resemblance. However, because there are two hooks per rami and that the crests are unusually long, this might be a different species. However, because there is no material available, the final decision about its specific status must be postponed. Until then, the species might be regarded as species inquerenda.

title: A Novel Approach for Identification and Linking of Short Quotations in Scholarly Texts and Literary Works
Creators: name: Arnold, Frederik

Publisher: name: UNSPECIFIED
Year: 2025

description: We present two approaches for the identification and linking of short quotations between scholarly works and literary works: ProQuo, a specialized pipeline, and ProQuoLM, a more general language model based approach. Our evaluation shows that both approaches outperform a strong baseline and the overall performance is on the same level. We compare the performance of ProQuoLM on texts with and without (page) reference information and find that reference information is not used. Based on our findings, we propose the following steps for future improvements: further analysis of the influence of a bigger context window for better handling of long distance references and the introduction of positional information of the literary work so that reference information can be utilized by ProQuoLM.
Reflections on Topology - Viewpoints on Abelian Projections

Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: This talk discusses two topological features in non-abelian gauge theories, related by the notion of abelian projection and the Hopf invariant. Minimising the energy of the non-linear sigma model with a Skyrme-like term (the Faddeev-Niemi model), can be identified with a non-linear maximal abelian gauge fixing of the SU(2) gauge vacua with a winding number equal to the Hopf invariant. In the context of abelian projection the Hopf invariant can also be associated to a monopole world line, through the Taubes winding, measuring its contribution to topological charge. Calorons with non-trivial holonomy provide an explicit realisation. We discuss the identification of its constituent monopoles through degenerate eigenvalues of the Polyakov loop (the singularities or defects of the abelian projection). It allows us to study the correlation between the defect locations and the explicit constituent monopole structure, through a specific SU(3) example.

description: Understanding of rainfall–runoff model performance under non-stationary hydroclimatic conditions is limited. This study compared lumped (IHACRES), semi-distributed (HEC-HMS) and fully-distributed (SWATgrid) hydrological models to determine which most realistically simulates runoff in catchments where non-stationarity in rainfall–runoff relationships exists. The models were calibrated and validated under different hydroclimatic conditions (Average, Wet and Dry) for two heterogeneous catchments in southeast Australia (SEA). SWATgrid realistically simulates runoff in the smaller catchment under most hydroclimatic conditions but fails when the model is calibrated in Dry conditions and validated in Wet. All three models perform poorly in the larger catchment irrespective of hydroclimatic conditions. This highlights the need for more research aimed at improving the ability of hydrological models to realistically incorporate the physical processes causing non-stationarity in rainfall–runoff relationships. Although the study is focussed on SEA, the insights gained are useful for all regions which experience large hydroclimatic variability and multi-year/decadal droughts.

COMMENT
Doubtfully present in Algeria. The report of this European temperate species (Blockeel et al. 2014b) in Algeria is based on a single specimen collected by Gandoger, and its reliability is doubtful. Considering the difficulties encountered in locating this collection, the species could only be retained in the Algerian catalogue upon the discovery of new specimens.

All the different data sets coherently point to a value E*c=4.5 A.MeV for the apparent critical excitation energy. The critical exponents tau, sigma are compatible with the observation of a liquid-gas phase transition for these systems.

description: We have modelled the near-infrared to radio images of the Crab Nebula with a Bayesian SED model to simultaneously fit its synchrotron, interstellar and supernova dust emission. We infer an interstellar dust extinction map with an average $A_{\text{V}}$=1.08$\pm$0.38 mag, consistent with a small contribution (<22%) to the Crab's overall infrared emission. The Crab's supernova dust mass is estimated to be between 0.032 and 0.049 M$_{\odot}$ (for amorphous carbon grains) with an average dust temperature $T_{\text{dust}}$=41$\pm$3K, corresponding to a dust condensation efficiency of 8-12%. This revised dust mass is up to an order of magnitude lower than some previous estimates, which can be attributed to our different interstellar dust corrections, lower SPIRE flux densities, and higher dust temperature than were used in previous studies. The dust within the Crab is predominantly found in dense filaments south of the pulsar, with an average V-band dust extinction of $A_{\text{V}}$=0.20-0.39 mag, consistent with recent optical dust extinction studies. The modelled synchrotron power-law spectrum is consistent with a radio spectral index $α_{\text{radio}}$=0.297$\pm$0.009 and an infrared spectral index $α_{\text{IR}}$=0.429$\pm$0.021. We have identified a millimetre excess emission in the Crab's central regions, and argue that it most likely results from two distinct populations of synchrotron emitting particles. We conclude that the Crab's efficient dust condensation (8-12%) provides further evidence for a scenario where supernovae can provide substantial contributions to the interstellar dust budgets in galaxies.

This regular sound change validates the etymological connection in question. The etymon【南】for 'southern sky' has been identified in Sinitic, Germanic, Baltic, Slavic, Celtic, Albanian, Hellenic, Anatolian, Armenian, Indo-Iranian, some Tibeto-Burman, some Uralic and Hungarian. The etymon【陰】for 'dark' has been identified in Sinitic, Germanic and Gyalrong. In words of Western linguistics, the Proto-Indo-European root *nebh'moist, water from it damp, mist, fog, cloud' is newly identified in Sinitic, some TibetoBurman, some Uralic and Hungarian; the Proto-Germanic root *ēbanþ-/ēbunþ‘evening’ is identified in Sinitic and Gyalrong.

description: Three inactivated enterovirus A71 (EV-A71) vaccines have been widely vaccinated among children in the targeted age group in mainland China since mid-2016. However, comprehensive virological surveillance of hand, foot and mouth disease (HFMD) over multiple years after the use of EV-A71 vaccines has rarely been conducted. Using long-term data extracted from the Public Health and Clinical Center of Chengdu, we described the clinical, aetiological, and epidemiological characteristics of HFMD inpatients after the use of EV-A71 vaccines from 2017 through 2022. A total of 5115 patients were selected for analysis with a male-to-female ratio of 1.63:1 and were mostly under 5 years of age (97.6%). Among these cases, 4.3% presented with severe symptoms, and 4.1% of severe cases experienced significant complications. EV-A71 was no longer the major serotype for laboratory-confirmed HFMD, responsible for 15.6% of severe cases and 1.2% of mild cases. A significant downwards trend of EV-A71 infections was observed after the use of EV-A71 vaccines (P for trend < 0.001). Coxsackievirus A6 was the predominant pathogen, accounting for 63.5% of mild cases and 36.2% of severe cases. Coxsackievirus A10 (CV-A10) and A16 were sporadically detected, and an upwards trend was observed in the proportion of CV-A10 infections. This study provides baseline molecular epidemiology for the evaluation of EV-A71 vaccination impact and potential serotype replacement based on HFMD inpatients. Additional nationwide and population-based epidemiologic and serologic studies are essential to elucidate HFMD dynamics after the use of EV-A71 vaccines, and to inform public health authorities to introduce optimized intervention strategies.

description: Phytochemical investigation of Croton crassifolius roots afforded five sesquiterpenes (1–5), including two new sesquiterpenes 6S-hydroxy-cyperenoic acid (1) and crassifterpenoid A (5), together with three known compounds (2–4). The structures of the new compounds were determined by comprehensive spectroscopic methods, and their absolute configurations were determined by quantum chemical ECD calculation. Crassifterpenoid A (5) is the first germacrane-type sesquiterpene isolated from C. crassifolius, which enriched the diversity of chemical constituents in Croton crassifolius. In addition, the cytotoxicities of all compounds against human liver cancer lines HepG2 and Hep3B were determined, but none showed significant activity.

description: This article presents the results of a study of signs on a Bronze Age slab discovered in the vicinity of a heavily plowed mound near the settlement of Pyatikhatki. The slab belongs to the Dolmen archaeological culture. In the course of this research, it was proved that the Pyatikhatki slab is a unique measuring tool, that combines elements of sundial and water clock. It has all the cup marks of an analemmatic sundial, except for the presence of a precise analemma, which at that time, it seems, could not yet be built. The vertical gnomon moved only along the north-south line, and the time was determined approximately. Most likely, this was due to the lack of accuracy in measuring time using the water clock of that era. It is possible that it was their imperfection that was the incentive for the development of a new type of watch a sundial, which would allow measuring time over a long period with a higher accuracy.

description: Commutation or anticommutation relations quantized at equal instant time and commutation or anticommutation relations quantized at equal light-front time not only cannot be transformed into each other, they take completely different forms. While they would thus appear to describe different theories, we show that this is not in fact the case. By looking not at equal times but at unequal times, we show that unequal instant-time commutation or anticommutation relations are completely equivalent to unequal light-front time commutation or anticommutation relations. Light-front quantization and instant-time quantization are thus the same, with it being only the restriction to equal times that makes them look different. However for fermions there is a caveat, as the light-front anticommutation relations involve projection operators acting on the fermion fields. Nonetheless, not only can one still derive fermion unequal light-front time anticommutators starting from unequal instant-time ones, one can even derive unequal instant-time fermion anticommutators starting from unequal light-front time anticommutators even though the fermion projection operators that are relevant in the light-front case are not invertible. To establish the equivalence for gauge fields we present a quantization procedure that does not involve zero-mode singularities that are commonly encountered in light-front gauge field studies. We also study time-ordered products of fields, and again show the equivalence despite the fact that there are additional terms in the fermion light-front case. We establish our results first for free theories, and then to all orders in interacting theories though comparison of the instant-time and light-front Lehmann representations. Finally, we compare instant-time Hamiltonians and light-front Hamiltonians, and show that in the instant-time rest frame they give identical results.

description: We investigate the quantum-classical transition in the delta-kicked rotor and the attainment of the classical limit in terms of measurement-induced state-localization. It is possible to study the transition by fixing the environmentally induced disturbance at a sufficiently small value, and examining the dynamics as the system is made more macroscopic. When the system action is relatively small, the dynamics is quantum mechanical and when the system action is sufficiently large there is a transition to classical behavior. The dynamics of the rotor in the region of transition, characterized by the late-time momentum diffusion coefficient, can be strikingly different from both the purely quantum and classical results. Remarkably, the early time diffusive behavior of the quantum system, even when different from its classical counterpart, is stabilized by the continuous measurement process. This shows that such measurements can succeed in extracting essentially quantum effects. The transition regime studied in this paper is accessible in ongoing experiments.

description: The paper surveys the ways of building the absolute chronology of the ancient Near-East, with a special focus on Mesopotamia during the second millennium BC. There are two types of astronomical phenomena used for dating 2nd millennium Mesopotamia: eclipse observations and Venus observations. These phenomena are (to a large extent) cyclical and can therefore be calculated backward into the past. They can then be compared with existing "records" of astronomical observations. Depending on the presumed reliability of available documents and the retrospective calculations, a number of absolute datings can be proposed, for Egypt, for Assyria, for Anatolia, etc. Acceptable chronological schemes must accommodate available documents (King Lists, astronomical records, etc.), historical synchronisms and retrospective calculations of phenomena (Venus, eclipses, Sirius, etc.), as harmoniously as possible. There are several competing schemes: Long, High Middle, Low Middle, Short, not to mention Ultra-Short. On the whole, it would appear that the Low Middle chronology with the Fall of Babylon circa 1587 BC would best fit the whole set of available data.

description: Uncertainty in climate change impacts on river discharge in the Upper Awash Basin, Ethiopia, is assessed using five MIKE SHE hydrological models, six CMIP5 general circulation models (GCMs) and two representative concentration pathways (RCP) scenarios for the period 2071–2100. Hydrological models vary in their spatial distribution and process representations of unsaturated and saturated zones. Very good performance is achieved for 1975–1999 (NSE: 0.65–0.8; r: 0.79–0.93). GCM-related uncertainty dominates variability in projections of high and mean discharges (mean: –34% to +55% for RCP4.5, – 2% to +195% for RCP8.5). Although GCMs dominate uncertainty in projected low flows, inter-hydrological model uncertainty is considerable (RCP4.5: –60% to +228%, RCP8.5: –86% to +337%). Analysis of variance uncertainty attribution reveals that GCM-related uncertainty occupies, on average, 68% of total uncertainty for median and high flows and hydrological models no more than 1%. For low flows, hydrological model uncertainty occupies, on average, 18% of total uncertainty; GCM-related uncertainty remains substantial (average: 28%).

description: Interstellar graphene could be present in the interstellar medium (ISM), resulting from the photochemical processing of polycyclic aromatic hydrocarbon (PAH) molecules and/or collisional fragmentation of graphitic particles. Indeed, by comparing the observed ultraviolet (UV) extinction and infrared (IR) emission of the diffuse ISM with that predicted for graphene, as much as $\sim$ 2% of the total interstellar carbon could have been locked up in graphene without violating the observational constraints. While the possible detection of planar C$_{24}$, a small piece of a graphene sheet, has been reported towards several Galactic and extragalactic planetary nebulae, graphene has not yet been detected in interstellar environments. In this work, we search for the characteristic IR features of C$_{24}$ at $\sim$ 6.6, 9.8, 20 $μm$ toward Sgr B2, a high-mass star formation region, and find a candidate target toward R.A. (J2000) = $267^{\circ}.05855$ and Decl. (J2000) = $-28^{\circ}.01479$ in Sgr B2 whose Spitzer/IRS spectra exhibit three bands peaking at $\sim$ 6.637, 9.853 and 20.050 $μm$ which appear to be coincident with that of C$_{24}$. Possible features of C$_{60}$ are also seen in this region. The candidate region is a warm dust environment heated by massive stars or star clusters, associated with a WISE spot (a tracer of star-formation activity), close to the HII region candidate IRAS 17450-2759, and is surrounded by seven young stellar object candidates within $\sim$ 5$^{\prime}$, suggesting that the creation and/or excitation of C$_{24}$ could be related to star formation activities.

description: Calibration of hydrological models is challenging in high-latitude regions where hydrometric data are minimal. Process-based models are needed to predict future changes in water supply, yet often with high amounts of uncertainty, in part, from poor calibrations. We demonstrate the utility of stable isotopes (18O, 2H) as data employed for improving the amount and type of information available for model calibration using the isoWATFLOODTM model. We show that additional information added to calibration does not hurt model performance and can improve simulation of water volume. Isotope-enabled calibration improves long-term validation over traditional flow-only calibrated models and offers additional feedback on internal flowpaths and hydrological storages that can be useful for informing internal water distribution and model parameterization. The inclusion of isotope data in model calibration reduces the number of realistic parameter combinations, resulting in more constrained model parameter ranges and improved long-term simulation of large-scale water balance.

description: Rainfall events largely control hydrological processes occurring on and in the ground, but the performance of climate models in reproducing rainfall events has not been investigated enough to guide selection among the models when making hydrological projections. We proposed to compare the durations, intensities, and pause periods, as well as depths of rainfall events when assessing the accuracy of general circulation models (GCMs) in reproducing the hydrological characteristics of observed rainfall. We also compared the sizes of design storm events and the frequency and severity of drought to demonstrate the consequences of GCM selection. The results show that rainfall and extreme hydrological event projections could significantly vary depending on climate model selection and weather stations, suggesting the need for a careful and comprehensive evaluation of GCM in the hydrological analysis of climate change. The proposed methods are expected to help to improve the accuracy of future hydrological projections for water resources planning.

description: We study the dynamics of one and two dimensional disordered lattice bosons/fermions initialized to a Fock state with a pattern of $1$ and $0$ particles on $A$ and ${\bar A}$ sites. For non-interacting systems we establish a universal relation between the long time density imbalance between $A$ and ${\bar A}$ site, $I(\infty)$, the localization length $ξ_l$, and the geometry of the initial pattern. For alternating initial pattern of $1$ and $0$ particles in 1 dimension, $I(\infty)=\tanh[a/ξ_l]$, where $a$ is the lattice spacing. For systems with mobility edge, we find analytic relations between $I(\infty)$, the effective localization length $\tildeξ_l$ and the fraction of localized states $f_l$. The imbalance as a function of disorder shows non-analytic behaviour when the mobility edge passes through a band edge. For interacting bosonic systems, we show that dissipative processes lead to a decay of the memory of initial conditions. However, the excitations created in the process act as a bath, whose noise correlators retain information of the initial pattern. This sustains a finite imbalance at long times in strongly disordered interacting systems.

description: The isomonodromy deformation method is applied to the scaling limits in the linear NxN matrix equations with rational coefficients to obtain the deformation equations for the algebraic curves which describe the local behavior of the reduced versions for the relevant isomonodromy deformation equations. The approach is illustrated by the study of the algebraic curve associated to the n-large asymptotics in the sequence of the bi-orthogonal polynomials with cubic potentials.
