description: The optimisation of scenarios and design of real-time-control in tokamaks, especially for machines still in design phase, requires a comprehensive exploration of solutions to the Grad-Shafranov (GS) equation over a high-dimensional space of plasma and coil parameters. Emulators can bypass the numerical issues in the GS equation, if a large enough library of equilibria is available. We train an ensemble of neural networks to emulate the typical shape-control targets (separatrix at midplane, X-points, divertor strike point, flux expansion, poloidal beta) as a function of plasma parameters and active coil currents for the range of plasma configurations relevant to spherical tokamaks with a super-X divertor, with percent-level accuracy. This allows a quick calculation of the classical-control shape matrices, potentially allowing real-time calculation at any point in a shot with sub-ms latency. We devise a hyperparameter sampler to select the optimal network architectures and quantify uncertainties on the model predictions. To generate the relevant training set, we devise a Markov-Chain Monte Carlo algorithm to produce large libraries of forward Grad-Shafranov solutions without the need for user intervention. The algorithm promotes equilibria with desirable properties, while avoiding parameter combinations resulting in problematic profiles or numerical issues in the integration of the GS equation.

description: Miscarriage is a very sad event. Along with the grief of losing your baby, you mayalso be feeling feelings of guilt or anger. Also physically it will be very painful anddifficult for you to bear it.If we understand abortion, then it can help in overcoming it.What is abortion?The death of a baby before 24 weeks of pregnancy is called a miscarriage.Sometimes it is also called spontaneous abortion.The termination of the foetus or pregnancy in the womb is called 'abortion' and thisaction is more painful for a mother mentally and physically. Doctors use drugs andsurgery to perform an abortion. A miscarriage can happen even if the unborn baby diesspontaneously or naturally, which is called 'miscarriage' in common language.

description: Probabilistic topic models are widely used to discover latent topics in document collections, while latent feature vector representations of words have been used to obtain high performance in many NLP tasks. In this paper, we extend two different Dirichlet multinomial topic models by incorporating latent feature vector representations of words trained on very large corpora to improve the word-topic mapping learnt on a smaller corpus. Experimental results show that by using information from the external corpora, our new models produce significant improvements on topic coherence, document clustering and document classification tasks, especially on datasets with few or short documents.

description: Some models allowing explicit calculation of periodic instantons and evaluation of their action are studied with regard to transitions from classical to quantum behaviour as the temperature is lowered and tunneling sets in. It is shown that (beyond a critical value of a coupling) the spin system considered acquires a first order transition as a result of the field dependence of its effective mass, whereas models with constant mass exhibit only second order transitions.

description: Low energy Raman continuum and the redistribution of the continuum to a peak (2Δ-peak) in the superconducting state have been studied in Tl-Ba-(Ca)-Cu-O superconductors with single (Tl-2201) and double (Tl-2212) CuO_2 layer. The 2Δ/k_BT_c ratios in A_1g and B_1g symmetries are larger for Tl-2212 than for Tl-2201. The B_1g/A_1g gap ratio is also larger in Tl-2212. The A_1g intensities of the continuum and the 2Δ-peak are significantly weaker than the B_1g intensities in Tl-2201, but are comparable in Tl-2212. This shows that the Coulomb screening is much stronger in Tl-2201. The change from Tl-2201 to Tl-2212 of the normalized A_1g 2Δ-peak intensity is identical within experimental error to that of normalized A_1g continuum intensity. This suggests that the excitations forming the 2Δ-peak and the continuum couple to light by the same mechanism.

description: Fracton phase of matter host fractionalized topological quasiparticles with restricted mobility. A wide variety of fracton models with abelian excitations had been proposed and extensively studied while the candidates for non-Abelian fracton phases are less explored. In this work, we investigate the effect of twisted defect in abelian fracton models. The twisted defect is launched by introducing a branch cut line hosting anyon condensate. In particular, these twisted defects, which alter different types of quasiparticles, carry projective non-Abelian zero modes. En route, such defects can be engineered via strong onsite hybridization along a branch cut which provides wide tunability and flexibility in experiment platforms. The braiding of twisted defects with projective non-Abelian Berry phase renders a new avenue toward fault-tolerant quantum computation.

We explain why the phonon mode softens at the N point for bcc-structured metals.

description: The origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may have seeded from the direct collapse of dark energy domains with density significantly higher than the surrounding regions. The mechanism of the origin of such domains relies on the inflationary evolution of a scalar field acting in D dimensions, which is associated with the cosmological constant in our four-dimensional spacetime manifold. Inner space quantum fluctuations of the field during inflation are responsible for the spatial variations of the dark energy density in our space. This finding holds particular significance, especially considering recent evidence from pulsar timing array observations, which supports the existence of a stochastic gravitational wave background consisting of SMBH mergers.

description: The usual Berry phase for a Majorana zero-energy state is zero. In this manuscript, we propose a generalized geometric phase for Majorana zero-energy state, which is non-zero for the electron or hole, respectively. We calculate these non-zero geometric phases in a Ferromagnet (FI)/Topological Insulator (TI)/Superconductor (SC) hybrid system, whose magnetization can be manipulated by changing adiabatically the spin degree of freedom. The non-zero geometric phases have potential application on the topological quantum computation treatment of Majorana zero-energy modes. We also discuss the non-adiabatic geometric phase associated with Majorana zero-energy state by the path integral method.

description: Topologically stable cellular partitions of D dimensional spaces are studied. A complete statistical description of the average structural properties of such partition is given in term of a sequence of D/2-1 (or (D-1)/2) variables for D even (or odd). These variables are the average coordination numbers of the 2k-dimensional polytopes (2k < D) which make the cellular structure. A procedure to built D dimensional space partitions trough cell-division and cell-coalescence transformations is presented. Classes of structures which are invariant under these transformations are found and the average properties of such structures are illustrated. Homogeneous partitions are constructed and compared with the known structures obtained by Voronoi partitions and sphere packings in high dimensions.

description: We present 22\,901 OB spectra of 16\,032 stars identified from LAMOST DR5 dataset. A larger sample of OB candidates are firstly selected from the distributions in the spectral line indices space. Then all 22\,901 OB spectra are identified by manual inspection. Based on a sub-sample validation, we find that the completeness of the OB spectra reaches about $89\pm22$\% for the stars with spectral type earlier than B7, while around $57\pm16$\% B8--B9 stars are identified. The smaller completeness for late B stars is lead to the difficulty to discriminate them from A0--A1 type stars. The sub-classes of the OB samples are determined using the software package MKCLASS. With a careful validation using 646 sub-samples, we find that MKCLASS can give fairly reliable sub-types and luminosity class for most of the OB stars. The uncertainty of the spectral sub-type is around 1 sub-type and the uncertainty of the luminosity class is around 1 level. However, about 40\% of the OB stars are failed to be assigned to any class by MKCLASS and a few spectra are significantly misclassified by MKCLASS. This is likely because that the template spectra of MKCLASS are selected from nearby stars in the solar neighborhood, while the OB stars in this work are mostly located in the outer disk and may have lower metallicity. The rotation of the OB stars may also be responsible for the mis-classifications. Moreover, we find that the spectral and luminosity classes of the OB stars located in the Galactic latitude larger than 20$^\circ$ are substantially different with those located in latitude smaller than 20$^\circ$, which may either due to the observational selection effect or hint a different origin of the high Galactic latitude OB stars.

When superconductors on both sides have triplet symmetries, the Josephson current is enhanced at low temperature due to the zero-energy states formed near the interface. Measuring Josephson current in this s/o/s junction, we can identify parity of the superconductor.

description: This study highlights the unpredictable nature of road accidents and the global challenge of reducing their occurrence. Despite disciplined driving, accidents can still happen, particularly in accident-prone areas. The proposed solution is Roller Road Barriers, especially effective on elevated roadways, as they absorb impact energy, convert it to rotational energy, and redirect traffic, preventing vehicles from crashing through immovable barriers. The study, conducted in Megadike Access Road in San Fernando, Pampanga, and with information from Negros Occidental, tests the effectiveness of these barriers. The research includes vehicle classification, driver interviews, and a miniature model demonstration. The implementation of Roller Road Barriers is suggested as a measure to decrease road accidents and enhance safety in the specified areas for drivers, commuters, and the community.

description: The consortium formed by the Angolan education institution ISPTEC, the Angolan company MIAPIA SURVEYS, and the Spanish multinational SATEC has, in collaboration with the University of Oviedo, implemented for the first time in Angola the Microbioal Oil Survey Technique (MOST - Hitzman, D., 1959) at the professional laboratories of ISPTEC in Luanda. MOST is a surface geochemical prospecting technique that enables the identification of oil prospects by detecting hydrocarbon-oxidizing bacteria targeting light hydrocarbons (C4-butanol) in soil samples. This method is based on the premise that hydrocarbons trapped in reservoirs are released in varying quantities (microseeps) to the surface, creating anomalous concentrations of light hydrocarbons (C1-C5) in soil, which promote the growth of oxidizing bacteria (Schumacher D., 1996). As an example of the potential that the MOST technique offers within the recently framework of revitalizing the exploration of Angola's onshore basins promoted by the National Petroleum, Gas, and Biofuels Agency (ANPG), this study focuses on applying this technique to reevaluate the petroleum potential of one of the historical mature fields of the Kwanza Basin: the Quenguela Norte Oil Field (Figure 1), which was in production from 1967 to 2000. The objective of the study is to identify areas with oil potential that may still contain hydrocarbon accumulations by conducting a MOST-based microbiological soil campaign. The results are then compared against the geological context and historical production data of the field.

description: Configurable software systems are prone to configuration errors, resulting in significant losses to companies. However, diagnosing these errors is challenging due to the vast and complex configuration space. These errors pose significant challenges for both experienced maintainers and new end-users, particularly those without access to the source code of the software systems. Given that logs are easily accessible to most end-users, we conduct a preliminary study to outline the challenges and opportunities of utilizing logs in localizing configuration errors. Based on the insights gained from the preliminary study, we propose an LLM-based two-stage strategy for end-users to localize the root-cause configuration properties based on logs. We further implement a tool, LogConfigLocalizer, aligned with the design of the aforementioned strategy, hoping to assist end-users in coping with configuration errors through log analysis.
 To the best of our knowledge, this is the first work to localize the root-cause configuration properties for end-users based on Large Language Models~(LLMs) and logs. We evaluate the proposed strategy on Hadoop by LogConfigLocalizer and prove its efficiency with an average accuracy as high as 99.91%. Additionally, we also demonstrate the effectiveness and necessity of different phases of the methodology by comparing it with two other variants and a baseline tool. Moreover, we validate the proposed methodology through a practical case study to demonstrate its effectiveness and feasibility.

description: During the nineteen-tens and -twenties the British Empire was transformed into the British Commonwealth of Nations and the League of Nations was created and began its work. This thesis argues that from the perspective of a loosely defined group of public academics and politicians from the British Empire, here identified as imperialist-internationalists, these two events were dual processes, as they considered both the Commonwealth and the League natural steps of progression from the British Empire of the early twentieth century. By analysing selected perspectives on empires as peacemakers from antiquity to the late nineteenth century and the education of the imperialist-internationalists it is argued that they belonged to an established Western tradition of seeing empires as a positive form of peaceful international organisation. However, like many contemporaries, they were critical of the traditional model of empire where all power was centred in the imperial metropolis as a valid form of international governance. With a focus on their published contributions to the public debate, supported by selected archival material, it is demonstrated how the imperialist-internationalists promoted the existence of what they named the British Commonwealth of Nations before it was given any kind of legal recognition, attributing specific values of democracy and equality to its constituent parts. Likewise, it is demonstrated how they identified the outbreak of World War One as an opportunity to reorganise the world to promote international cooperation, and how they worked to use British imperial experience in the formation of the League and formulation of the Covenant. Finally, it is argued that E.H. Carr’s rejection of the interwar thinkers as utopians was unjust as they tried to use what they thought was an established model. As a consequence, applying Carr’s lens has limited the existing scholarship of several members of the imperialist-internationalists.

description: We have obtained low-dispersion spectra of NGC 3227 with the Space Telescope Imaging Spectrograph (STIS) to study the intrinsic UV absorption and the reddening of the nucleus in this Seyfert 1 galaxy. The UV spectra show a wealth of absorption lines at the systemic redshift that span a wide range in ionization state (Mg I to N V). The equivalent widths of the lines are consistent with our earlier prediction that a ``lukewarm absorber'' (T= 18,000 K at the ionized face) with a substantial column of gas [N(H) = 2 x 10^21 cm^-2] is present and likely responsible for the reddening of the nucleus. The lukewarm absorber is also responsible for most of the absorption in the X-rays at energies less than 1 keV, although a more highly ionized ``warm absorber'' is needed to account for the O VII and O VIII ionization edges. In addition, we require a small column [N(H) = 5 x 10^19 cm^-2] of cold gas to match the strengths of the neutral and singly-ionized lines in the UV spectra. NGC 3227 is the first Seyfert galaxy in which a strong link between the reddening and intrinsic UV absorption has been found. By comparing our STIS UV and optical spectra with those of the unreddened Seyfert NGC 4151, we have determined a reddening curve for the nuclear continuum source in NGC 3227 over the 1150 - 10,200 A range. The reddening curve does not show a 2200 AA bump, and is steeper in the UV than reddening curves derived for the Galaxy, LMC, and SMC, suggesting a preponderence of small dust grains near the nucleus.

 Thiotricha acrantha Meyrick, 1908: 440; 1925: 102; Gaede, 1937: 303; Clarke, 1969: 448; Ivinskis et al., 1984: 38. TL: Assam, India. TD: NHMUK.
 Type material (Figs 67E, F, 74C). Holotype ♂, INDIA, Assam, Khasi Hills, ix.1906, genitalia slide no. J. F.G.C. 8337 (NHMUK).
 Additional material examined. INDIA: 1 ♂, 1 ♀, same original data as holotype except X.1906 for male and 1925[?] for female (abdomens are missing for both) (NHMUK). CHINA: Yunnan Province: 1 ♂, Xiaodifangxincun (24.87°N, 98.75°E), 2116 m, Tengchong County, 12.viii.2014, leg. Kaijian Teng, Shurong Liu and Hua Rong, genitalia slide no. LGE18366; 2 ♂♂, 2 ♀♀, Baoshan (24.82°N, 98.78°E), 2009 m, 17, 20.vii.2015, leg. Kaijian Teng and Xia Bai, genitalia slide nos. LGE 16079m, LGE16080f, LGE 16294m, LGE18367f.
 Diagnosis. Adult (Fig. 21H). Wingspan 9.5−13.0 mm. The male labial palpus of T. acrantha has segment II slightly longer than I and as long as III, and the hair pencil of segment II is present. The forewing is white to cream, and it is marked with fuscous streaks on dorsum and near apex. The costal strigulae are indistinct in this species. The apical spot is sometimes tinged with rosy pink scales on its inner margin. The male genitalia (Fig. 45E) can easily be recognized by the slender and long anellus lobe and the aedeagus scobinate medially. The female genitalia (Fig. 62E) are diagnosed by the short segment VIII and the ovate corpus bursae with the posterior 1/3 covered with minute spines.
 Distribution. China (Yunnan), India.
 Remarks. The superficial appearance of T. acrantha closely resembles the species of the subocellea -group, but the genital structures, especially in female, are quite different from the latter as the medial sclerotization of female sternum VIII are absent in T. acrantha and the signum is round as in the pancratiastis -group. In the male genitalia, the aedeagus of T. acrantha is narrower and not dilated basally as in the subocellea -group and the middle of aedeagus is not smooth but scobinate. The genetic analysis does not agree with the placement as well (unpublished data), and the subdivision for this species within Thiotricha needs to be further discussed. This species is recorded from China for the first time.

description: We review the critical behaviour of the Driven Lattice Gas (DLG) model. As a result, we obtain a novel Langevin equation for the DLG which depends on the microscopic transition probabilities. We then show how this dependence affects the critical behaviour of the the DLG placing the finite and the infinite driving field cases into different universality classes. Two other well known anisotropic, conservative, non-equilibrium models, the two-temperature model and the randomly driven model (RDLG) are also studied. It is shown that the RDLG with infinite averaged field and the two-temperature model with infinite parallel temperature fall in the same universality class as the infinitely driven DLG. A Langevin equation for the two-layer DLG is also presented.

description: We study random multidimensional assignment problems where the costs decompose into the sum of independent random variables. In particular, in three dimensions, we assume that the costs $W_{i,j,k}$ satisfy $W_{i,j,k}=a_{i,j}+b_{i,k}+c_{j,k}$ where the $a_{i,j},b_{i,k},c_{j,k}$ are independent exponential rate 1 random variables. Our objective is to minimize the total cost and we show that w.h.p. a simple greedy algorithm is a $(3+o(1))$-approximation. This is in contrast to the case where the $W_{i,j,k}$ are independent exponential rate 1 random variables. Here all that is known is an $n^{o(1)}$-approximation, due to Frieze and Sorkin.
The radial velocities of the RS CVn star UX Ari. A triple system with a binary on the same line of sight

description: UX Ari belongs to the class of very active RS CVn stars and has recently been the target of surface (Doppler) imaging. Although this technique needs a quite accurate determination of the orbit (in order to have the correct period for phasing and the correct Doppler shift correction of the line profiles) we found only one, quite old orbit solution, which has subsequently been used by everyone. We used published radial velocities (RVs), supplemented by a large number (124) of our own recent, high-accuracy RVs of both the primary (K0 IV) and the secondary (G5 V) to improve the orbit of UX Ari. In addition to the improved set of parameters, we found that the gamma velocity of the system is systematically changing over time. It seems that UX Ari is a triple system. Actually, a third star is weakly present in the spectrum. While its RV is also changing, it is not a member of the system, but happens to be on the same line of sight. Finally, conclusions about the physical parameters of the objects from the orbits are presented.

description: This paper deals with Tikhonov regularization for linear and nonlinear ill-posed operator equations with wavelet Besov norm penalties. We focus on $B^0_{p,1}$ penalty terms which yield estimators that are sparse with respect to a wavelet frame. Our framework includes among others, the Radon transform and some nonlinear inverse problems in differential equations with distributed measurements. Using variational source conditions it is shown that such estimators achieve minimax-optimal rates of convergence for finitely smoothing operators in certain Besov balls both for deterministic and for statistical noise models.
Generalized persistence exponents: an exactly soluble model

description: It was recently realized that the persistence exponent appearing in the dynamics of nonequilibrium systems is a special member of a continuously varying family of exponents, describing generalized persistence properties. We propose and solve a simplified model of coarsening, where time intervals between spin flips are independent, and distributed according to a Lévy law. Both the limit distribution of the mean magnetization and the generalized persistence exponents are obtained exactly.

description: A two dimensional random hopping model with N-species and π-flux is studied. The field theory at the band center is shown to be in the universality class of GL(4m,R)/O(4m) nonlinear sigma model. Vanishing beta function suggests delocalised states at the band center. Contrary to the similar universality class with broken time reversal symmetry, the present class is expected to have at least two fixed point. Large N-systems are shown to be in the weak-coupling fixed point, which is characterized by divergent density of state, while small N systems may be in the strong-coupling fixed point.

“We Work Hard, We Play Hard!”—Fictional Gayspeak in the Italian Dubbing of “The Simpsons”: A Queer Audiovisual Translation Study
Creators: name: Passa, Davide
Publisher: name: Iperstoria
Year: 2021
Subjects: English linguistics; Queer Audiovisual Translation Studies; gayspeak; The Simpsons; dubbing

description: Despite being an animated sitcom, The Simpsons is a satire of contemporary American society and culture. This article intends to apply a queer perspective to Audiovisual Translation Studies, in line with what Flotow (2019) defined the third approach to gender-focused audiovisual translation, that is, the investigation of gay and queer source texts and their treatment in the target text. This study deals with the process of sexualisation of fictional gay men through fictional gayspeak. The analysis focuses on excerpts where the Italian dubbing departs from the original, and the strategies that have been used to reproduce gayspeak into Italian. The investigation rests on the idea that translation is a gender-constructing activity implying the queering of the target text, which is a process that varies from language to language.

Towards a ‘COOPING’ Model for the Investigation of Gamers’ Online Conversations in English
Creators: name: Iaia, Pietro Luigi
Publisher: name: Iperstoria
Year: 2021
Subjects: English as a Lingua Franca; online communication; virtual transient international groups; computer-mediated communication; conversation analysis

description: This paper proposes a cognitive-functional investigation of gamers’ uses of English in online communication, in order to enquire into the possibility of introducing a model that could be called COOPING (‘COOperation Principles between INternet Gamers’). COOPING was devised at the University of Salento, and it was conceived as a further development of both Grice’s maxims and Guido’s principles describing English lingua-franca uses in intercultural exchanges. The main research hypothesis is that the interactants’ awareness of the need to cooperate to reach shared targets prompts them to select a common linguistic means, which is usually a variation of English, when different linguacultural backgrounds come into contact. This paper will detail the four phases of COOPING—Evaluation, Acknowledgment, Negotiation, and Manner—which are expected to reflect the steps that players follow when they intend to cooperate in these virtual communities. Through an analysis of the selected corpus of conversations, this study will illustrate that gamers: (phases 1 and 2 of the Model) examine and evaluate the interlocutors’ behavior in order to assess their cooperative attitude; (phase 3) decide to select English when community members come from different linguistic and cultural backgrounds; and (phase 4) generate conversation turns that are characterized by specific features, from authentication, to meaning negotiation, to creative and critical modifications to the standard norms, trying to pursue reciprocal understanding and communication.

description: We study the dynamics of the striped phase, which has previously been suggested to be the ground state of a doped antiferromagnet. Starting from the t-J model, we derive the classical equation governing the motion of the charged wall by using a ficticious spin model as an intermediate step. A wave-like equation of motion is obtained and the wall elasticity and mass density constants are derived in terms of the t and J parameters. The wall is then regarded as an elastic string which will be trapped by the pinning potential produced by randomly distributed impurities. We evaluate the pinning potential and estimate the threshold electric field which has to be applied to the system in order to release the walls. Besides, the dynamics of the stripe in the presence of a bias field below the threshold is considered and the high- and low-temperature relaxation rates are derived.
