description: It has long been known that perturbative calculations can be performed in a soliton sector of a quantum field theory by using a soliton Hamiltonian, which is constructed from the defining Hamiltonian by shifting the field by the classical soliton solution. It is also known that even if tadpoles are eliminated in the vacuum sector, they remain in the soliton sector. In this note we show, in the case of quantum kinks at two loops, that the soliton sector tadpoles may be removed by adding certain quantum corrections to the classical solution used in this construction. Stated differently, the renormalization condition that the soliton sector tadpoles vanish may be satisfied by renormalizing the soliton solution.

description: It has been reported that traveling waves propagate periodically and stably in sub-excitable systems driven by noise [Phys. Rev. Lett. \textbf{88}, 138301 (2002)]. As a further investigation, here we observe different types of traveling waves under different noises and periodic forces, using a simplified Oregonator model. Depending on different noises and periodic forces, we have observed different types of wave propagation (or their disappearance). Moreover, the reversal phenomena are observed in this system based on the numerical experiments in the one-dimensional space. As an explanation, we regard it as the effect of periodic forces. Thus, we give qualitative explanations to how reversal phenomena stably appear, which seem to arise from the mixing function of the periodic force and the noise. And the output period and three velocities (the normal, the positive and the negative) of the travelling waves are defined and their relationship with the periodic forces, along with the types of waves, are also studied in sub-excitable system under a fixed noise intensity.

description: We present effective field theories for the weakly coupled Weyl-$\mathrm{Z}_2$ semimetal, as well as the holographic realization for the strongly coupled case. In both cases, the anomalous systems have both the chiral anomaly and the $\mathrm{Z}_2$ anomaly and possess topological quantum phase transitions from the Weyl-$\mathrm{Z}_2$ semimetal phases to partly or fully topological trivial phases. We find that the topological phase transition is characterized by the anomalous transport parameters, i.e. the anomalous Hall conductivity and the $\mathrm{Z}_2$ anomalous Hall conductivity. These two parameters are nonzero at the Weyl-$\mathrm{Z}_2$ semimetal phase and vanish at the topologically trivial phases. In the holographic case, the different behavior between the two anomalous transport coefficients is discussed. Our work reveals the novel phase structure of strongly interacting Weyl-$\mathrm{Z}_2$ semimetal with two pairs of nodes.

description: The 248nm and 193nm photodissociation of submonolayer quantities of CH$_3$Br and CH$_3$I adsorbed on thin layers of n-hexane indicate that the dissociation is caused by dissociative electron attachment from sub-vacuum level photoelectrons created in the copper substrate. The characteristics of this photodissociation-- translation energy distributions and coverage dependences show that the dissociation is mediated by an image potential state which temporarily traps the photoelectrons near the n-hexane--vacuum interface, and then the charge transfers from this image state to the affinity level of a co-adsorbed halomethane which then dissociates.

Idaea foedata: Beljaev & Mironov 2019: 277 (Sakhalin).
Material examined. 2 ♀, Razdolnoe, 26.VII.2019, 16–17.VIII.2020; 1 ♀, Yasnomorskoe, 15–16.VIII.2020.
Distribution. Russia (S RFE: SW Sakhalin), Japan (Hokkaido, Honshu, Kyushu),? North Korea, South Korea,? China.
Remarks. The finding of I. foedata in Sakhalin significantly expands its distribution range to the northeast. All examined specimens were collected on the dry forb meadows situated on the southern insolated slopes.
Its indication from the island in Beljaev & Mironov (2019) is a first true report of this species from Russia. The previous note of this species from the Kurils (Kunashir) (Vasilenko 1992: 282) was reidentified as Idaea jakima (Butler) (Beljaev & Mironov 2019). In the continental Far East true I. foedata has not yet been discovered.
In the BOLD, the specimens of “ Idaea foedata ” from Primorskii Krai (BIN ID: ABA2911, the Sequence ID and corresponding GBIF occurrence specimens see Table 2), judging by the photo of the specimen with the BOLD sequence ID GWOSU787-11 from this set, are Idaea salutaria (Christoph), as well as the specimen of “ Idaea jakima ” from Korea (sequence ID GBMNF22112-22). Apparently, the two other “ Idaea foedata ” from Primorsky Krai in the GBIF (occurrence 886474998: Zoologische Staatssammlung 2022, and occurrence 3023329857: Kurina 2022i) also do not belong to I. foedata. Distribution of I. foedata in China needs to be verified, as the specimens of “ Idaea foedata ” in the BOLD (BIN ID: AAB5151), by DNA-barcoding (Makhov & Lukhtanov 2021), and in appearance correspond to Idaea falckii (Hedemann). The same applies to the data on “ Idaea foedata ” from China in the GBIF. Due to the frequent errors in species identification in the group I. foedata — I. jakima — I. salutaria (Christoph) by appearance, all their old literature records require revision.

The deep music of tradition in the works of Kōda Rohan
Creators: name: Cleary, Richard James
Publisher: name: University of British Columbia
Year: 2010

description: Rising to prominence on a wave of nationalistic reaction to two decades of intense Western influence, Koda Rohan (1867-1947) re-discovered the Japanese past in the form of the Genroku period (1688-1703) poets Saikaku and Basho, and led the way to a literary flowering in the 1890's. As this bloom faded and the tides of modernization continued to rise capturing literary circles in its currents, Rohan placed himself against the flow, dedicated to the vital task of preserving the values of the East Asian tradition. It is for this reason his work is valuable today: in his writing the voice of tradition speaks with great depth, breadth and beauty. This thesis explores the character of Rohan's writing by examining three of his novels. In the first work considered the focus is on the iridividual. The second treats the individual within the framework of society. The last is concerned with the shared cultural experience known as history. The introduction attempts to place the writer and his work in historical perspective. In recognition that the life was admired as much as the creations of his pen, the first chapter is a biographical sketch. Chapter Two suggests an approach to the writing itself, noting salient points of style, influences, and development. Attention is focused on Rohan's use of traditional poetic devices, the commanding rhythm of his prose, and the underlying qualities of his narrative voice. Analyzing thematic and stylistic features, the third, fourth, and fifth;.chapters treat three representative works of fiction. Chapter Three deals with Taidokuro ("Encounter With A Skull"), an early work. The analysis shows how classical forms and materials were employed in an innovative, powerful, and, at times, humorous fashion in a piece of writing dealing with the problem of attachment and suffering due to human passion. In Chapter Four the discussion of Goju no To ("The Five-Storied Pagoda"), the work which won Rohan an enduring reputation, centers around its portrayal of the energies of the individual and society in opposition. In bold, vigorous language the novel dramatizes the conflicting ideals of individual aspiration and social harmony, while suggesting a resolution represented by the balance and majesty of the pagoda. Chapter Five examines Rohan's view of history as expressed in his novel Renkanki ("Record of Linked Rings"). A late work, it is constructed with a series of biographical portraits of historical figures in tenth-century Heian Japan. Rohan's regeneration of the past reveals his vision of the fabric of history as woven by the threads of karma and recorded in the songs of poets. The conclusion is devoted to observations on difficulties in reappraising Rohan's work and reflections on his place in the history of Japanese literature.

description: Land use planning is an important task for every country in the world to ensure the sustainable use of land resources for economic and social development activities. However, many land use plans have not achieved their desired effectiveness due to a lack of consideration and evaluation of factors affecting the land use planning implementation process. This study was conducted to answer the following question: what are the main factors influencing the land use planning process in Vietnam? In this study, we use multivariate regression to identify the main factors influencing land use planning in Vietnam, including the economic factor group; institutional and policy factor group; urbanisation factor group; planning factor group; social factor group; environmental factor group; and organisational and implementation factor group. The results identified five groups of factors influencing land use planning in the Dan Phuong district through the influencing factor analysis method, including policy (Po), economy (Ec), society (So), environment (En), and others (Ot). In addition, the linear regression model obtained for land use planning in Dan Phuong district is as follows: land use planning = 0.408Po + 0.454Ec + 0.398So + 0.368En + 0.259Ot. In which the group of factors with the strongest influence was the Eco factors (β = 0.454), the second was the Po factors (β = 0.408), the third was the So factors (β = 0.398), the fourth was the En factors (β = 0.368), and lastly, there were the Ot factors (β = 0.259). The results of the analysis were used to plan land use effectively and according to local conditions. This can help managers to find solutions for the sustainable use of land resources in the future.

Black hole-neutron star mergers are unlikely multi-messenger sources

description: The promise by the LIGO/Virgo/Kagra (LVK) collaboration to detect black hole--neutron star (BH--NS) mergers via gravitational wave (GW) emission has recently been fulfilled with the detection of GW200105 and GW200115. Mergers of BH--NS binaries are particularly exciting for their multi-messenger potential, since the GW detection can be followed by an electromagnetic (EM) counterpart (kilonova, gamma-ray burst, afterglow) that can reveal important information on the equation of state (EOS) of NSs and the nature of the BH spin. We carry out a statistical study of the binary stars that evolve to form a BH--NS binary and compute the rate of merger events that can be followed by an EM counterpart. We find that $\gtrsim 50\%$ of the mergers can lead to an EM counterpart only in the case BHs are born highly spinning ($χ_{\rm BH}\gtrsim 0.7$), while this fraction does not exceed about $30\%$ for stiff NS EOSs and a few percent for soft NS EOSs for low-spinning BHs ($χ_{\rm BH}\lesssim 0.2$), suggesting that a high rate of EM counterparts of BH--NS would provide support for high natal BH spins. However, the possibilities that BHs are born with near-maximal spins and that NS internal structure is described by a stiff EOS are disfavored by current LVK constraints. Considering that these values only represent an upper limit to observe an EM counterpart due to current observational limitations, as in brightness sensitivity and sky localization, BH--NS mergers are unlikely multi-messenger sources.

description: We present the first results from the ALHAMBRA survey. ALHAMBRA will cover a relatively wide area (4 square degrees) using a purposely-designed set of 20 medium-band filters, down to an homogeneous magnitude limit AB~25 in most of them, adding also deep near-infrared imaging in JHK. To this aim we are using the Calar Alto 3.5m telescope. A small area of the ALHAMBRA survey has already been observed through our complete filter set, and this allows for the first time to check all the steps of the survey, including the pipelines that have been designed for the project, the fulfilment of the data quality expectations, the calibration procedures, and the photometric redshift machinery for which ALHAMBRA has been optimised. We present here the basic results regarding the properties of the galaxy sample selected in a 15x15 square arcmin area of the ALHAMBRA-8 field, which includes approximately 10000 galaxies with precise photometric redshift measurements. In a first estimate, approximately 500 of them must be galaxies with z>2.

description: We develop a method of transverse momentum dependent (TMD) operator expansion that yields the TMD factorization theorem on the operator level. The TMD operators are systematically ordered with respect to TMD-twist, which allows a certain separation of kinematic and genuine power corrections. The process dependence enters via the boundary conditions for the background fields. As a proof of principle, we derive the TMD factorization up to the next-to-leading power $(\sim q_T/Q)$ at the next-to-leading order for any process with two detected states.

description: In this article, we propose a simple inferential method for a wide class of panel data models with a focus on such cases that have both serial correlation and cross-sectional dependence. In order to establish an asymptotic theory to support the inferential method, we develop some new and useful higher-order expansions, such as Berry-Esseen bound and Edgeworth Expansion, under a set of simple and general conditions. We further demonstrate the usefulness of these theoretical results by explicitly investigating a panel data model with interactive effects which nests many traditional panel data models as special cases. Finally, we show the superiority of our approach over several natural competitors using extensive numerical studies. Supplementary materials for this article are available online.

description: We investigate the effect of noise on Random Boolean Networks. Noise is implemented as a probability $p$ that a node does not obey its deterministic update rule. We define two order parameters, the long-time average of the Hamming distance between a network with and without noise, and the average frozenness, which is a measure of the extent to which a node prefers one of the two Boolean states. We evaluate both order parameters as function of the noise strength, finding a smooth transition from deterministic ($p=0$) to fully stochastic ($p=1/2$) dynamics for networks with $K\le2$, and a first order transition at $p=0$ for $K>2$. Most of the results obtained by computer simulation are also derived analytically. The average Hamming distance can be evaluated using the annealed approximation. In order to obtain the distribution of frozenness as function of the noise strength, more sophisticated self-consistent calculations had to be performed. This distribution is a collection of delta peaks for K=1, and it has a fractal sructure for $K>1$, approaching a continuous distribution in the limit $K\gg1$.

Our major innovations include: (1) a near-optimal slicing scheme, and a path-optimization strategy that considers both complexity and compute density; (2) a three-level parallelization scheme that scales to about 42 million cores; (3) a fused permutation and multiplication design that improves the compute efficiency for a wide range of tensor contraction scenarios; and (4) a mixed-precision scheme to further improve the performance. Our simulator effectively expands the scope of simulatable RQCs to include the 10*10(qubits)*(1+40+1)(depth) circuit, with a sustained performance of 1.2 Eflops (single-precision), or 4.4 Eflops (mixed-precision)as a new milestone for classical simulation of quantum circuits; and reduces the simulation sampling time of Google Sycamore to 304 seconds, from the previously claimed 10,000 years.

While the original inspiration was the work of Dress and Terhalle in phylogenetics, and of Faltings, Kapranov, Keel and Tevelev in algebraic geometry, our tropical algorithms will also be applicable to problems in other fields of mathematics.

description: We propose a simple dynamic exchange-correlation kernel of the uniform electron gas. We model the reduction of the electron-electron interaction due to short-range exchange-correlation effects by introducing a frequency-dependent error-function effective interaction. By imposing the fulfillment of the compresibility and the third-frequency-moment sum rules, as well as the correct asymptotic behavior at large wave vectors, we find an accurate and simple dynamic exchange-correlation kernel that accurately reproduces the wave-vector analysis and the imaginary-frequency analysis of the correlation energy of the uniform electron gas.

description: We use chiral perturbation theory to study the extraction of pion electromagnetic polarizabilities from lattice QCD. Chiral extrapolation formulae are derived for partially quenched QCD, and quenched QCD simulations. On a torus, volume dependence of electromagnetic observables is complicated by SO(4) breaking, as well as photon zero-mode interactions. We determine finite volume corrections to the Compton scattering tensor of pions. We argue, however, that such results cannot be used to ascertain volume corrections to polarizabilities determined in lattice QCD with background field methods. Connection is lacking because momentum expansions are not permitted in finite volume. Our argument also applies to form factors. Volume effects for electromagnetic moments cannot be deduced from finite volume form factors.

description: The current document, titled ’The final version of TIME4CS Clustering Activities and user engagement activities report’, has been developed within the framework of the TIME4CS project which is funded by the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No 101006201.

The purpose of this Deliverable is to present an overview of the communication and dissemination activities completed by the TIME4CS consortium in the 36 months of the project, in order to generate enhanced collaborations with other relevant international organisations and projects on the topic of citizen science (hereinafter referred to as “sister projects”).

This report gives an overview of what clustering represents for TIME4CS and details what the project can offer from this perspective. The engagement strategy is also discussed, and details are presented for each initially proposed collaboration. The document then presents an overview of the TIME4CS Case studies and the Citizen Science Helix.

This report also discusses the future plans that the consortium has in place in order to continue cross-collaboration activities.

description: We discuss two dimensional N-extended supersymmetry in Euclidean signature and its R-symmetry. For N=2, the R-symmetry is SO(2)\times SO(1,1), so that only an A-twist is possible. To formulate a B-twist, or to construct Euclidean N=2 models with H-flux so that the target geometry is generalised Kahler, it is necessary to work with a complexification of the sigma models. These issues are related to the obstructions to the existence of non-trivial twisted chiral superfields in Euclidean superspace.

description: It is well established from cosmological simulations that dark matter haloes are not precisely self-similar and an additional parameter, beyond their concentration, is required to accurately describe their spherically-averaged mass density profiles. We present, for the first time, a model to consistently predict both halo concentration, $c$, and this additional `shape' parameter, $α$, for a halo of given mass and redshift for a specified cosmology. Following recent studies, we recast the dependency on mass, redshift, and cosmology to a dependence on `peak height'. We show that, when adopting the standard definition of peak height, which employs the so-called spherical top hat (STH) window function, the concentration--peak height relation has a strong residual dependence on cosmology (i.e., it is not uniquely determined by peak height), whereas the $α$--peak height relation is approximately universal when employing the STH window function. Given the freedom in the choice of window function, we explore a simple modification of the STH function, constraining its form so that it produces universal relations for concentration and $α$ as a function of peak height using a large suite of cosmological simulations. It is found that universal relations for the two density profile parameters can indeed be derived and that these parameters are set by the linear power spectrum, $P(k)$, filtered on different scales. We show that the results of this work generalise to any (reasonable) combination of $P(k)$ and background expansion history, $H(z)$, resulting in accurate predictions of the density profiles of dark matter haloes for a wide range of cosmologies.

La Divina Mimesis
Iconografia ingiallita
photography

description: The present essay focuses on the Iconografia ingiallita (Yellowed Iconography), at the conclusion of La Divina Mimesis, the book that Pier Paolo Pasolini finally published in 1975. The section is composed of photographs that are not intended to illustrate the meaning of the text, but rather to share the same reflected light of the photographic medium with it. The set of photographs represents a reticent autobiography that has to be edited by the reader-viewer according to a possible logic of continuity or discontinuity. Neither the verbal nor the figurative text get in line with progressive time; on the contrary, they form a narrative heterochrony. In fact, in Pasolini’s last poetics, “to yellow” does not imply death, but life, the survival of a sherd of past in the present day, and a hindrance to neo-capitalistic time. Pasolini mobilises some specific concepts – Benjamin’s “Aura” and “Now-Time”, Auerbach’s “Figure” and Tylor’s “Survival” – within a Dantesque framework, in which photography takes up a material place in the attempt to get an expositio sui in multiple media and of multiple times o his own intellectual career.

description: Novel NaIL detector (5x6 inch) was investigated for aims of neutron detection in wide energy range. It has been found that the detector together with its known ability to detect the γ- radiation is also allows to distinguish neutron signals in three quasi-independent ways. It sensitive to neutron fluxes on a level down to $10^{-3}$ $cm^{-2}$ $s^{-1}$. In the work intrinsic α- background and neutron detection efficiency for the NaIL detector were obtained. Experimental data was compared with results of Geant4 Monte Carlo (MC).

description: We analyze the bipartite and multipartite entanglement for the ground state of the one-dimensional XY model in a transverse magnetic field in the thermodynamical limit. We explicitly take into account the spontaneous symmetry breaking in order to explore the relation between entanglement and quantum phase transitions. As a result we show that while both bipartite and multipartite entanglement can be enhanced by spontaneous symmetry breaking deep into the ferromagnetic phase, only the latter is affected by it in the vicinity of the critical point. This result adds to the evidence that multipartite, and not bipartite, entanglement is the fundamental indicator of long range correlations in quantum phase transitions.

description: We study reheating after the end of inflation in models where the inflaton is the superpartner of goldstino and is charged under a gauged $U(1)$ R-symmetry. We consider two classes of models -- one is small field characterized by an almost flat Kähler space, and the other large field characterized by a hyperbolic Kähler space $SU(1,1)/U(1)$, while in both cases the inflaton superpotential is linear due to the R-symmetry. The inflationary observables of our models fit within 2$σ$ CMB values. Upon coupling the inflaton sector to the (supersymmetric) Standard Model, we compute the MSSM parameters, mass spectrum, and decay modes of the inflaton, with the resulting reheating temperature around $10^8$ GeV. We also find that both models can accommodate superheavy LSP dark matter, depending on the parameter choice.

description: Complex networks are characterized by heterogeneous distributions of the degree of nodes, which produce a large diversification of the roles of the nodes within the network. Several centrality measures have been introduced to rank nodes based on their topological importance within a graph. Here we review and compare centrality measures based on spectral properties of graph matrices. We shall focus on PageRank, eigenvector centrality and the hub/authority scores of HITS. We derive simple relations between the measures and the (in)degree of the nodes, in some limits. We also compare the rankings obtained with different centrality measures.

description: The Spitzer Extended Deep Survey (SEDS) as a deep and wide mid-infrared (MIR) survey project provides a sample of 500000+ sources spreading 1.46 square degree and a depth of 26 AB mag (3$σ$). Combining with the previous available data, we build a PSF-matched multi-wavelength photometry catalog from u band to 8$μ$m. We fit the SEDS galaxies spectral energy distributions by the local galaxy templates. The results show that the SEDS galaxy can be fitted well, indicating the high redshift galaxy ($z \sim 1$) shares the same templates with the local galaxies. This study would facilitate the further study of the galaxy luminosity and high redshift mass function.

description: Purpose: To implement and evaluate a new dictionary-based technique for native myocardial T1 and T2 mapping using Cartesian sampling. Methods: The proposed technique (Multimapping) consisted of single-shot Cartesian image acquisitions in 10 consecutive cardiac cycles, with inversion pulses in cycle 1 and 5, and T2 preparation (TE: 30ms, 50ms and 70ms) in cycles 8-10. Multimapping was simulated for different T1 and T2, where entries corresponding to the k-space centers were matched to acquired data. Experiments were performed in a phantom, 16 healthy subjects and three patients with cardiovascular disease. Results: Multimapping phantom measurements showed good agreement with reference values for both T1 and T2, with no discernable heart-rate dependency for T1 and T2 within the range of myocardium. In vivo mean T1 in healthy subjects was significantly higher using Multimapping (T1=1114+/-14ms) compared to the reference (T1=991+/-26ms) (p<0.01). Mean Multimapping T2 (47.1+/-1.3ms) and T2 spatial variability (5.8+/-1.0ms) was significantly lower compared to the reference (T2=54.7+/-2.2ms, p<0.001; spatial variability=8.4+/-2.0ms, p<0.01). Increased T1 and T2 was detected in all patients using Multimapping. Conclusions: Multimapping allows for simultaneous native myocardial T1 and T2 mapping with a conventional Cartesian trajectory, demonstrating promising in vivo image quality and parameter quantification results.

description: Iniforis turristhomae (Holten, 1802)
Rios (1970, 1975, 1985, 1994, 2009) presented the main records of I. turristhomae for Brazil. Yet, these were questioned by Leal (1991) and Fernandes et al. (2013), who suggested the correct species was Iniforis pseudothomae Rolán & Fernández-Garcés, 1993. After examining all lots referred to I. turristhomae at the MORG collection, where Dr Rios worked for most of his life, we conclude that almost all of them indeed corresponded to I. pseudothomae, and no shell of I. turristhomae was seen. Hence, the record of I. turristhomae in Brazil is invalidated, and the southernmost range of this species lies somewhere between Venezuela and the Guyanas.

CHEF: A Cheap and Fast Pipeline for Iteratively Cleaning Label Uncertainties (Technical Report)

description: High-quality labels are expensive to obtain for many machine learning tasks, such as medical image classification tasks. Therefore, probabilistic (weak) labels produced by weak supervision tools are used to seed a process in which influential samples with weak labels are identified and cleaned by several human annotators to improve the model performance. To lower the overall cost and computational overhead of this process, we propose a solution called CHEF (CHEap and Fast label cleaning), which consists of the following three components. First, to reduce the cost of human annotators, we use Infl, which prioritizes the most influential training samples for cleaning and provides cleaned labels to save the cost of one human annotator. Second, to accelerate the sample selector phase and the model constructor phase, we use Increm-Infl to incrementally produce influential samples, and DeltaGrad-L to incrementally update the model. Third, we redesign the typical label cleaning pipeline so that human annotators iteratively clean smaller batch of samples rather than one big batch of samples. This yields better over all model performance and enables possible early termination when the expected model performance has been achieved. Extensive experiments show that our approach gives good model prediction performance while achieving significant speed-ups.
