description: Magnetically confined hollow electron beams for controlled halo removal in high-energy colliders such as the Tevatron or the LHC may extend traditional collimation systems beyond the intensity limits imposed by tolerable material damage. They may also improve collimation performance by suppressing loss spikes due to beam jitter and by increasing capture efficiency. A hollow electron gun was designed and built. Its performance and stability were measured at the Fermilab test stand. The gun will be installed in one of the existing Tevatron electron lenses for preliminary tests of the hollow-beam collimator concept, addressing critical issues such as alignment and instabilities of the overlapping proton and electron beams.

description: Purpose: Limited research informs management of cognitive-communication difficulties following traumatic brain injury (TBI) in older adulthood. The purpose of this study was to understand the characteristics and practice of speech-language pathologists (SLPs) working with people who sustained TBI at ≥55 years and more specifically their management of cognitive-communication difficulties with this population. This included assessment and treatment practices, resource needs, barriers to practice, and impact to service delivery from COVID-19 restrictions. Method: A cross-sectional survey-based design with non-probability sampling of SLPs working in Australia with adults with TBI was utilised. Descriptive statistics and content analysis were used for analysis of survey data. Result: Fifty responses were eligible for inclusion. Participants predominantly worked in inpatient rehabilitation (48%), acute (40%), and community settings (36%). Service delivery to adults who sustained TBI at ≥55 years commonly included cognitive-communication management. Assessment and treatment trends are described. Most SLPs (74%) perceived barriers to cognitive-communication management, often relating to time and funding, that existed prior to the COVID-19 pandemic. Pandemic restrictions presented additional challenges. Conclusion: Research relating to cognitive-communication difficulties following TBI in older adulthood is required to support evidence-based practice and inform services for older adults who sustain TBI.

description: Introdução: Os cistos pancreáticos são diagnosticados com frequência crescente devido ao uso generalizado de imagens transversais. Os cistos pancreáticos podem ser detectados em 40 a 50 por cento dos pacientes que se submetem a ressonância magnética abdominal por razões não relacionadas. A frequência aumenta com a idade. Objetivo: discutir a classificação dos cistos pancreáticos. Metodologia: Revisão de literatura integrativa a partir de artigos das bases científicas de dados da Scielo, da PubMed e da BVS. Tal pesquisa ocorreu no período de março a maio de 2024, com descritores em inglês “Classification” e “Pancreatic Cysts” e seus correspondentes em português. Incluíram-se artigos completos dos últimos cinco anos (2019-2024), com total de 35 estudos. Após leitura dos resumos, excluíram-se estudos de outras categorias, com 05 artigos para leitura na íntegra. Resultados e Discussão: Lesões císticas do pâncreas podem ser divididas patologicamente em coleções de fluidos inflamatórios, cistos pancreáticos não neoplásicos e neoplasias císticas pancreáticas (PCNs). Além disso, tumores sólidos podem desenvolver degeneração cística. Existem seis subtipos de PCNs com vários graus de potencial maligno: Neoplasias serosas; Neoplasias císticas mucinosas (MCNs); Neoplasias mucinosas papilares intraductais (IPMNs); Neoplasias papilares oncocíticas intraductais (IOPNs); Neoplasias tubulopapilares intraductais (NTIPs) e Neoplasias pseudopapilares sólidas (NPS). Diferenciar PCNs de outras lesões císticas, bem como determinar o subtipo de PCN, é importante para avaliar o potencial maligno. Enquanto cistoadenomas serosos quase não têm potencial maligno, os PCNs produtores de mucina (MCNs e neoplasias intraductais) e SPNs têm. Conclusão: Um cisto pancreático é um tipo de tumor que cresce no pâncreas ou dentro dele. Ele é tipicamente líquido por dentro, com uma pele externa. Menos de 1% dos cistos pancreáticos se tornam cancerígenos, mas os profissionais de saúde os mantêm sob vigilância, só por precaução. Se o seu médico descobrir um cisto pancreático na sua varredura de imagem, ele irá classificá-lo imediatamente como baixo, médio ou alto risco, com base na imagem e se você tem sintomas. Se for de baixo risco, provavelmente não há nada com que se preocupar. Se for de médio ou alto risco, ele irá tratá-lo de acordo com suas diretrizes. A maioria dos cistos pancreáticos simplesmente ficará sob vigilância. Os profissionais de saúde ficam de olho neles para ver se eles mudam ao longo do tempo.

description: We present a comparison of the parameters of accretion disc outflows and the jet of the broad-line radio galaxy 3C 111 on sub-pc scales. We make use of published X-ray observations of ultra-fast outflows (UFOs) and new 43GHz VLBA images to track the jet knots ejection. We find that the superluminal jet coexists with the mildly relativistic outflows on sub-pc scales, possibly indicating a transverse stratification of a global flow. The two are roughly in pressure equilibrium, with the UFOs potentially providing additional support for the initial jet collimation. The UFOs are much more massive than the jet, but their kinetic power is probably about an order of magnitude lower, at least for the observations considered here. However, their momentum flux is equivalent and both of them are powerful enough to exert a concurrent feedback impact on the surrounding environment. A link between these components is naturally predicted in the context of MHD models for jet/outflow formation. However, given the high radiation throughput of AGNs, radiation pressure should also be taken into account. From the comparison with the long-term 2-10keV RXTE light curve we find that the UFOs are preferentially detected during periods of increasing flux. We also find the possibility to place the UFOs within the known X-ray dips-jet ejection cycles, which has been shown to be a strong proof of the disc-jet connection, in analogue with stellar-mass black holes. However, given the limited number of observations presently available, these relations are only tentative and additional spectral monitoring is needed to test them conclusively.

description: The genus Zelkova (Ulmaceae) has occurred in Europe and Southwest Asia since the Eocene represented mostly by the fossil-species Z. zelkovifolia. Currently, relict populations of Z. abelicea, Z. sicula and Z. carpinifolia can be found in Crete, Sicily and the Euxino-Hyrcanian province, respectively. To reveal relationships between extinct and extant Zelkova species, we compared fossil Miocene leaves of Z. zelkovifolia and leaves of extant species using morphological leaf characteristics and statistical methods (Tukey’s test, discrimination analysis, principal component analysis, agglomeration). The fossil leaves of Z. zelkovifolia appeared more variable and generally intermediate between all three extant species. The lowest level of significant differences was found between Z. zelkovifolia and Z. abelicea in the leaves from fertile shoots and between Z. zelkovifolia and Z. sicula leaves from vegetative long shoots. The intermediate positions of fossil leaves of Z. zelkovifolia between leaves of Z. abelicea, Z. sicula and Z. carpinifolia could indicate that the extinct species was an ancestor of all three extant taxa. Consequently, this result suggests divergence between Z. abelicea, Z. sicula and Z. carpinifolia no earlier than the late Miocene and/or during the Pliocene.

description: By testing the classical correlation violation between two systems, the random number can be expanded and certified without applying classical statistical method. In this work, we propose a new random number expansion protocol without entanglement, and the randomness can be guaranteed only by the 2-dimension quantum witness violation. Furthermore, we only assume that the dimensionality of the system used in the protocol has a tight bound, and the whole protocol can be regarded as a semi-device independent black-box scenario. Comparing with the device independent random number expansion protocol based on entanglement, our protocol is much easier to implement and test.

description: Documenting the context in which data are collected is an integral part of the scientific research lifecycle. In field-based research, contextual information provides a detailed description of scientific practices and thus enables data interpretation and reuse. For field data, losing contextual information often means losing the data altogether. Yet, documenting the context of distributed, collaborative, field-based research can be a significant challenge due to the unpredictable nature of real-world settings and to the high degree of variability in data collection methods and scientific practices of different researchers. In this article, we propose the use of microblogging as a mechanism to support collection, ingestion, and publication of contextual information about the variegated digital artifacts that are produced in field research. We perform interviews with scholars involved in field-based environmental and urban sensing research, to determine the extent of adoption of Twitter and similar microblogging platforms and their potential use for field-specific research applications. Based on the results of these interviews as well as participant observation of field activities, we present the design, development, and pilot evaluation of a microblogging application integrated with an existing data collection platform on a handheld device. We investigate whether microblogging accommodates the variable and unpredictable nature of highly mobile research and whether it represents a suitable mechanism to document the context of field research data early in the scientific information lifecycle.

description: Hypothesis of quark binding through condensation of gluons inside hadrons is formulated in the context of a renormalization group procedure for effective particles (RGPEP) in the light-front (LF) Hamiltonian approach to QCD. At the momentum scales of relative motion of hadronic constituents that are comparable with Lambda_QCD, the hypothetical boost-invariant constituent dynamics is identified using gauge symmetry. The resulting picture of mesons and baryons closely resembles constituent quark models with harmonic oscillator potentials, shares some features of AdS/QCD, and can be systematically studied using RGPEP in QCD.

description: Invasions by alien plants pose a significant threat to biodiversity, having negative impacts on species richness, community, and ecosystems. Protected areas and small islands could be particularly affected by the presence of non-native plants that pose high threats to their biodiversity. Several surveys were made under the life project “Puffinus Tavolara” (LIFE12 NAT/IT/000416) between 2014 and 2015 to detect the presence of non-native plant species in the Marine Protected Area of Tavolara (Sardinia, Italy). The aim of the present work was to produce an updated inventory of the alien flora of the Island of Tavolara and the nearby Isola Piana. A list of 58 non-native taxa was produced, assessing their accidental or voluntary introduction, residence and invasive status, and applying an adapted A-WRA and EPPO prioritisation methods on the alien flora of these islands. Importantly, the results of the two methods applied are quite different, but they are both useful and informative for the prioritisation and management of invasive alien plants.

description: We evaluate the electron transmission through a dangling-bond wire on Si(100)-H (2x1). Finite wires are modelled by decoupling semi-infinite Si electrodes from the dangling-bond wire with passivating H atoms. The calculations are performed using density functional theory in a non-periodic geometry along the conduction direction. We also use Wannier functions to analyze our results and to build an effective tight-binding Hamiltonian that gives us enhanced insight in the electron scattering processes. We evaluate the transmission to the different solutions that are possible for the dangling-bond wires: Jahn-Teller distorted ones, as well as antiferromagnetic and ferromagnetic ones. The discretization of the electronic structure of the wires due to their finite size leads to interesting transmission properties that are fingerprints of the wire nature.

description: An Optical Transition Radiation monitor has been developed for the proton beam-line of the T2K long base-line neutrino oscillation experiment. The monitor operates in the highly radioactive environment in proximity to the T2K target. It uses optical transition radiation, the light emitted from a thin metallic foil when the charged beam passes through it, to form a 2D image of a 30 GeV proton beam. One of its key features is an optical system capable of transporting the light over a large distance out of the harsh environment near the target to a lower radiation area where it is possible to operate a camera to capture this light. The monitor measures the proton beam position and width with a precision of better than 500 μm, meeting the physics requirements of the T2K experiment.

description: A remarkable fraction of supernovae (SNe) have no obvious host galaxy. Two possible explanations are that (i) the host galaxy is simply not detected within the sensitivity of the available data or that (ii) the progenitor is a hypervelocity star that has escaped its parent galaxy. We use the Type IIb SN 2009Z as a prototype of case (i), an example of how a very faint (here Low Surface Brightness; LSB) galaxy can be discovered via the observation of a seemingly host-less SN. By identifying and studying LSB galaxies that host SNe related to the death of massive stars, we can place constraints on the stellar population and environment of LSB galaxies, which at present are poorly understood. From an HI spectrum, a redshift of z = 0.02513+-0.00001 and an HI mass of (2.96+-0.12) 10^9 M_sun are computed. This redshift is consistent with that obtained from optical emission lines of SN 2009Z. Furthermore, a gas mass fraction of f_g = 0.87+-0.04 is obtained, one of the highest fractions ever measured. The host galaxy shows signs of recently enhanced star formation activity with a far-UV derived extinction-corrected Star Formation Rate (SFR) of 0.44+-0.34 M_sun/yr. Based on the B-band luminosity we estimate an extinction-corrected metallicity following the calibration by Pilyugin (2001) of 12 + log(O/H) = 8.24+-0.70. The presence of a Type IIb SN in an LSB galaxy suggests, contrary to popular belief, that massive stars can be formed in this type of galaxies. Furthermore, our results imply that LSB galaxies undergo phases of small, local burst activity intermittent with longer phases of inactivity.

description: Naturalisation is the most crucial stage along the ecological process of introduction-naturalisation-invasion continuum. Therefore, reporting the transition of alien plant species at the naturalised stage along the continuum can be crucial for the early warning and rapid response in invasion management. Here we report Ranunculus repens as a new distribution record from Kashmir Himalaya. We provide a floristic account of this newly naturalised species and photographic illustrations of the distinguishing characters from an allied species, R. bulbosus, with which it is misidentified in the region. We also investigated the ecological aspects of this naturalised species by undertaking quadrat sampling in the R. repens-dominated community. Our results revealed that R. repens show positive association with those native species in the community which possess similar traits, but show interestingly negative association with other alien species found within the same community, thus hinting towards habitat filtering among the alien species pool in the region. Hopefully, the present study will validate report of R. repens from this Himalayan region, facilitate its field identification, guide control strategies at this early stage of naturalisation when chances of management success are maximum and prompt further studies on its potential invasion risk.

description: During stellar core collapse, which eventually leads to a supernovae explosion, the stalled shock is unstable due to the standing accretion shock instability (SASI). This instability induces large-scale non spherical oscillations of the shock, which have crucial consequences on the dynamics and the geometry of the explosion. While the existence of this instability has been firmly established, its physical origin remains somewhat uncertain. Two mechanisms have indeed been proposed to explain its linear growth. The first is an advective-acoustic cycle, where the instability results from the interplay between advected perturbations (entropy and vorticity) and an acoustic wave. The second mechanism is purely acoustic and assumes that the shock is able to amplify trapped acoustic waves. Several arguments favouring the advective-acoustic cycle have already been proposed, however none was entirely conclusive for realistic flow parameters. In this article we give two new arguments which unambiguously show that the instability is not purely acoustic, and should be attributed to the advective-acoustic cycle. First, we extract a radial propagation timescale by comparing the frequencies of several unstable harmonics that differ only by their radial structure. The extracted time matches the advective-acoustic time but strongly disagrees with a purely acoustic interpretation. Second, we present a method to compute purely acoustic modes, by artificially removing advected perturbations below the shock. All these purely acoustic modes are found to be stable, showing that the advected wave is essential to the instability mechanism.

description: It has been theoretically predicted many decades ago that extremely massive stars that develop large oxygen cores will become dynamically unstable, due to electron-positron pair production. The collapse of such oxygen cores leads to powerful thermonuclear explosions that unbind the star and can produce, in some cases, many solar masses of radioactive 56Ni. For many years, no examples of this process were observed in nature. Here, I briefly review recent observations of luminous supernovae that likely result from pair-instability explosions, in the nearby and distant Universe.

description: This vegetation–environmental relation study is the first large-scale survey along 34 cross-shore transects in 650 km-coastal dune remnants of the south Caspian Sea, Iran. The five vegetation zones dedicated here seem to be driven by both zonal (climate, distance to the sea and pH) and azonal (salinity) factors. To assess conservation status, different attributes of Hdune diversity index, endemicity index (EI) and Naturalness (N) were estimated based on endemic, alien and total species contributions per plot. Contrary to Hdune index, EI followed a decreasing pattern across the coast–inland gradient, whereas N shows a unimodal pattern of distribution with the highest value at the mobile dune zone. Two main gradients of salinity and alkalinity shaping floristic composition are more prominent than climate, distance to the sea and the anthropogenic factors particularly when a full range of coastal habitats are considered. Human-related factors only partially explain the variability of the vegetation data and negatively affect naturalness and endemicity indices, even though their impact on community composition is aggravated in the western parts of the Caspian coasts. Both N and EI indices can be suggested as bioindicators for proper conservation strategies to preserve the last fragments of sand dunes of the Caspian Sea.

description: In this paper, with a survey through the Large Angle and Spectrometric Coronagraph (LASCO) data from 1996 to 2009, we present 11 events with plasma blobs flowing outwards sequentially along a bright coronal ray in the wake of a coronal mass ejection. The ray is believed to be associated with the current sheet structure that formed as a result of solar eruption, and the blobs are products of magnetic reconnection occurring along the current sheet. The ray morphology and blob dynamics are investigated statistically. It is found that the apparent angular widths of the rays at a fixed time vary in a range of 2.1-6.6 (2.0-4.4) degrees with an average of 3.5 (2.9) degrees at 3 (4) Rs, respectively, and the observed durations of the events vary from 12 h to a few days with an average of 27 h. It is also found, based on the analysis of blob motions, that 58% (26) of the blobs were accelerated, 20% (9) were decelerated, and 22% (10) moved with a nearly-constant speed. Comparing the dynamics of our blobs and those that are observed above the tip of a helmet streamer, we find that the speeds and accelerations of the blobs in these two cases differ significantly. It is suggested that these differences of the blob dynamics stem from the associated magnetic reconnection involving different magnetic field configurations and triggering processes.

description: Quercus pubescens and Q. virgiliana are the most cited taxa in the Italian deciduous oak forests floristic and phytosociological literature. According to some authors, Q. pubescens is typical of inland areas and higher altitudes whereas Q. virgiliana restricted to the coastal plain and the hilly belt. Seven pubescent oak populations distributed along an altitudinal transect in central Italy have been analyzed from a coenological, morphological and molecular point of view. The vegetation sampling was carried out using the phytosociological approach. Morphological variation of tree individuals was analyzed using 14 leaf traits, while leaf shape variation was investigated using the Procrustes ANOVA. Genetic analyses were carried out through twelve EST-SSRs markers. Results: only the leaf pubescence exhibited discriminating power among all the leaf morphological traits considered. Very low differences in the leaf-shape emerged from geometric morphometric analysis. Genetic analyses did not evidence statistically significant clusters. Bayesian analyses including data from genetically pure populations of Q. pubescens, Q. petraea and Q. frainetto assigned all the seven populations investigated to Q. pubescens. Neither the morphological nor the genetic results allowed to identify specimens attributable to Q. pubescens or Q. virgiliana nor to highlight a possible ecological-altitudinal vicariance between these two species.

description: The recovery of cosmic ray He nuclei of energy ~150-250 MeV/nuc in solar cycle #23 from 2004 to 2010 has been followed at the Earth using IMP and ACE data and at V2 between 74-92 AU and also at V1 beyond the heliospheric termination shock (91-113 AU). The correlation coefficient between the intensities at the Earth and at V1 during this time period is remarkable (0.921), after allowing for a ~0.9 year delay due to the solar wind propagation time from the Earth to the outer heliosphere. To describe the intensity changes and to predict the absolute intensities measured at all three locations we have used a simple spherically symmetric (no drift) two-zone heliospheric transport model with specific values for the diffusion coefficient in both the inner and outer zones. The diffusion coefficient in the outer zone, assumed to be the heliosheath from about 90 to 120 (130) AU, is determined to be ~5 times smaller than that in the inner zone out to 90 AU. This means the Heliosheath acts much like a diffusing barrier in this model. The absolute magnitude of the intensities and the intensity changes at V1 and the Earth are described to within a few percent by a diffusion coefficient that varies with time by a factor ~4 in the inner zone and only a factor of ~1.5 in the outer zone over the time period from 2004-2010. For V2 the observed intensities follow a curve that is as much as 25% higher than the calculated intensities at the V2 radius and at times the observed V2 intensities are equal to those at V1. At least one-half of the difference between the calculated and observed intensities between V1 and V2 can be explained if the heliosphere is squashed by ~10% in distance (non-spherical) so that the HTS location is closer to the Sun in the direction of V2 compared to V1.

description: We examine the evolution of the inner dark matter (DM) and baryonic density profile of a new sample of simulated field galaxies using fully cosmological, Lambda CDM, high resolution SPH + N-Body simulations. These simulations include explicit H2 and metal cooling, star formation (SF) and supernovae (SNe) driven gas outflows. Starting at high redshift, rapid, repeated gas outflows following bursty SF transfer energy to the DM component and significantly flatten the originally `cuspy' central DM mass profile of galaxies with present day stellar masses in the 10^4.5 -- 10^9.8 Msolar range. At z=0, the central slope of the DM density profile of our galaxies (measured between 0.3 and 0.7 kpc from their centre) is well fitted by rhoDM propto r^alpha with alpha \simeq -0.5 + 0.35 log_10(Mstar/10^8Msolar) where Mstar is the stellar mass of the galaxy and 4 < log_10 Mstar < 9.4. These values imply DM profiles flatter than those obtained in DM--only simulations and in close agreement with those inferred in galaxies from the THINGS and LITTLE THINGS survey. Only in very small halos, where by z=0 star formation has converted less than ~ 0.03% of the original baryon abundance into stars, outflows do not flatten the original cuspy DM profile out to radii resolved by our simulations. The mass (DM and baryonic) measured within the inner 500 pc of each simulated galaxy remains nearly constant over four orders of magnitudes in stellar mass for Mstar 10^9 Msolar. This finding is consistent with estimates for faint Local Group dwarfs and field galaxies. These results address one of the outstanding problems faced by the CDM model, namely the strong discrepancy between the original predictions of cuspy DM profiles and the shallower central DM distribution observed in galaxies.

description: DNA double-strand breaks (DSBs) represent a serious source of damage for all living things and thus there have been many quantitative studies of DSBs both in vivo and in vitro. Despite this fact, the processes that lead to their production have not yet been clearly understood, and there is no established theory that can account for the statistics of their production, in particular, the number of DSBs per base pair per unit Gy, here denoted by P1, which is the most important parameter for evaluating the degree of risk posed by DSBs. Here, using the single-molecule observation method with giant DNA molecules (166 kbp), we evaluate the number of DSBs caused by gamma-ray irradiation. We find that P1 is nearly inversely proportional to the DNA concentration above a certain threshold DNA concentration. A simple model that accounts for the marked decrease of P1 shows that it is necessary to consider the characteristics of giant DNA molecules as semiflexible polymers to interpret the intrinsic mechanism of DSBs.

description: We calculate the one- and two-photon scattering matrices of a pair of collocated non-identical two-level atoms coupled to a waveguide. We show that by proper choice of a two-photon input, the background fluorescence by the atoms may be completely quenched, as a result of quantum interference, and that when the atoms' detuning is smaller than their linewidths, extremely narrow fluorescence features emerge. Furthermore, the system emits a two-photon bound state which can display spatial oscillations/quantum beats, and can be tuned from bunched to anti-bunched statistics as the total photon energy is varied.

description: Taking the lower Yellow River basin as the study area, this study aims to construct ecological networks to mitigate the negative impacts of rapid urbanization on the ecosystem. Ecological sources were identified based on morphological spatial pattern analysis (MSPA), habitat quality and landscape connectivity. The ecological resistance surface was constructed and corrected by integrating natural and anthropogenic factors. The spatial range of ecological corridors and some of their key nodes were identified based on circuit theory. The ecological network (EN) was finally optimized using a similarity search and cost connectivity modules. The results show that the optimized ecological network structure is more stable than before. The EN includes 23 ecological sources with a total area of 5464.8 km2 and 30 ecological corridor clusters with a total area of 2205.92 km2. Through the internal landscape heterogeneity of the corridor, 28 ecological node areas and 75 barrier areas were identified as key protection and restoration areas, with a total area of 78.44 km2 and 372.79 km2, respectively. Through the construction and optimization of EN, this study identifies key areas for promoting ecological sustainability and provides a useful framework for coordinating regional ecological conservation and economic development.

description: This work analyzes the effects of cubic nonlinearities on certain resonant scattering anomalies associated with the dissolution of an embedded eigenvalue of a linear scattering system. These sharp peak-dip anomalies in the frequency domain are often called Fano resonances. We study a simple model that incorporates the essential features of this kind of resonance. It features a linear scatterer attached to a transmission line with a point-mass defect and coupled to a nonlinear oscillator. We prove two power laws in the small coupling \to 0 and small nonlinearity \to 0 regime. The asymptotic relation ~ C^4 characterizes the emergence of a small frequency interval of triple harmonic solutions near the resonant frequency of the oscillator. As the nonlinearity grows or the coupling diminishes, this interval widens and, at the relation ~ C^2, merges with another evolving frequency interval of triple harmonic solutions that extends to infinity. Our model allows rigorous computation of stability in the small and limit. In the regime of triple harmonic solutions, those with largest and smallest response of the oscillator are linearly stable and the solution with intermediate response is unstable.

description: We consider a two parameter family of $Z_2$ gauge theories on a lattice discretization $T(M)$ of a 3-manifold $M$ and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a parameter space $Γ$. We show that there is a region $Γ_0$ of $Γ$ where the partition function and the expectation value $$ of the Wilson loop for a curve $γ$ can be exactly computed. Depending on the point of $Γ_0$, the model behaves as topological or quasi-topological. The partition function is, up to a scaling factor, a topological number of $M$. The Wilson loop on the other hand, does not depend on the topology of $γ$. However, for a subset of $Γ_0$, $$ depends on the size of $γ$ and follows a discrete version of an area law. At the zero temperature limit, the spin-gauge model approaches the topological and the quasi-topological regions depending on the sign of the coupling constant.
