description: We consider domain walls that appear in supersymmetric QCD with Nf < Nc massive flavours. In particular, for 2 Nf < Nc we explicitly construct the domain walls that interpolate between vacua labeled by i and (i+ N_f). We show that these solutions are Bogomol'nyi-Prasad-Sommerfield (BPS) saturated for any value of the mass of the matter fields. This fact allows us to evaluate the large mass limit of these domain walls. We comment on the relevance of these solutions for supersymmetric gluodynamics.

Fermion Self-Energy and Chiral Symmetry Breaking from Four-Fermion and Gauge Interactions

description: The exact analytic solutions of the linearized Schwinger-Dyson equation of fermion self-energy are used to obtain the effective four-fermion and gauge coupling criticality curves for dynamical chiral symmetry breaking. The results show that when the zero-momentum gauge coupling $α(0) < α_0(0)$, the critical gauge coupling in the pure gauge interaction case, the minimal critical four-fermion coupling $β_{\rm min}$ is always non-zero and positive and will go up as the $α(0)$ decreases. The use of the exact solutions also allow us to make quite definite estimations of the momentum scales where chiral symmetry breaking would happen if the values of an infrared parameter $ξ$ are given separately.

description: Archinotodelphys polynesiensis Monniot, 1986
 Monniot (1986) noted variation in setal counts on several limbs within the material he used to describe A. polynesiensis. He interpreted this as intraspecific variation related to the utilization of different hosts; indeed, this variation was highlighted as a central theme of his paper. However, in the light of the much greater species level diversity available for this study and in the awareness of the relatively low variability in setal counts exhibited by copepods in general, we consider that A. polynesiensis is an unresolved complex of species. The holotype female of A. polynesiensis came from Ascidia archaia Sluiter, 1890, the type host, collected off Tikehau (Tuamotou) in French Polynesia. However Monniot (1986) also mentions additional material from Herdmania momus (Savigny, 1816) (as Pyura momus), as well as from Corella sp. collected at Moorea and Tikehau, and from Ascidia sp. collected at Tahiti, Moorea and Tikehau. Monniot documented substantial variation in many of the cephalosomic limbs in the material from these other hosts. In particular, he noted “enormous differences” in many appendages of the female from Herdmania momus, so he figured this female specimen separately. In the light of the new taxa studied here, we consider that there is now sufficient evidence to treat the copepod from H. momus as a distinct species, Archinotodephys momus sp. nov., which is diagnosed below. Huys & Boxshall (1991) examined one female of A. polynesiensis collected by Claude Monniot from a specimen of Molguloides vitrea (Sluiter, 1904) taken in The Philippines. They figured the mandible, maxillule, maxilla, maxilliped, fifth legs and genital double-somite of this specimen. There are significant differences between this specimen and the holotype female from Ascidia archaia but until new material becomes available there isn’t sufficient evidence to support the recognition of further separate species from this A. polynesiensis complex.

description: We perform a detailed study of the decays of the lighter top and bottom squarks (t~_1 and b~_1) in the Minimal Supersymmetric Standard Model (MSSM). We show that the decays into Higgs or gauge bosons, i.e. t~_1 -> b~_1 + (H^+ or W^+) and b~_1 -> t~_1 + (H^- or W^-), can be dominant in a wide range of the MSSM parameters due to the large Yukawa couplings and mixings of t~ and b~. Compared to the decays into fermions, such as t~_1 -> t + (neutralino_i or gluino) and t~_1 -> b + chargino_j, these bosonic decay modes can have significantly different decay distributions. We also show that the effect of the supersymmetric QCD running of the quark and squark parameters on the t~_1 and b~_1 decay branching ratios is quite dramatic. These could have an important impact on the search for t~_1 and b~_1 and the determination of the MSSM parameters at future colliders.

description: The Galactic centre supermassive black hole (SMBH), in sharp contrast with its complex environment, is characterized by only three classical parameters -- mass, spin, and electric charge. Its charge is poorly constrained. It is, however, usually assumed to be zero because of neutralization due to the presence of plasma. We revisit the question of the SMBH charge and put realistic limits on its value, timescales of charging and discharging, and observable consequences of the potential, small charge associated with the Galactic centre black hole. The electric charge due to classical arguments based on the mass difference between protons and electrons is $\lesssim 10^9\,{\rm C}$ and is of a transient nature on the viscous time-scale. However, the rotation of a black hole in magnetic field generates electric field due to the twisting of magnetic field lines. This electric field can be associated with induced charge, for which we estimate an upper limit of $\lesssim 10^{15}\,{\rm C}$. Moreover, this charge is most likely positive due to an expected alignment between the magnetic field and the black-hole spin. Even a small charge of this order significantly shifts the position of the innermost stable circular orbit (ISCO) of charged particles. In addition, we propose a novel observational test based on the presence of the bremsstrahlung surface brightness decrease, which is more sensitive for smaller unshielded electric charges than the black-hole shadow size. Based on this test, the current upper observational limit on the charge of Sgr A* is $\lesssim 3\times 10^{8}\,{\rm C}$.

 The reconstruction of the paleoclimatic and paleoceanographic development of the late Quaternary south polar ocean and adjacent continental areas in high temporal and spatial resolution is the main goal of our long-term study. During this expedition the sedimentary budget of biogenic and terrigenous components and their variability will be investigated. One objective of this leg is to continue the studies of former expeditions to gather more detailed paleoceanographic information on the eastern Pacific sector of the Southern Ocean for reconstruction of the distribution of water masses, frontal systems and sea ice, as well as information on high export productivity areas and their impact on global climate evolution. Thus, it will help us to broaden our understanding of the impact of environmental processes in the Southern Ocean on global climate. The second objective is to investigate the response of the West Antarctic Ice Sheet (WAIS) to Quaternary climatic changes. This ice sheet represents the most instable portion of Antarctic ice. The distribution pattern of the WAIS and its development can be deciphered from the sediment deposition in the study area. Previous investigations indicated that the WAIS collapsed once or multiple times during the past 0.75 million years. However there are also controversial findings. Since marine-geological records of glaciomarine deposition proximal to the WAIS are sparse, the exact timing and boundary conditions for such an event, which would result in a rise of the sea level of 5-6 m, are not yet known. The reconstruction of environmental conditions based on a multiproxy approach (this includes the investigations of sediment composition, microfossil assemblages and isotopic measurement of biogenic components) and its stratigraphic dating should substantially add to the knowledge of the WAIS history and its stability during a possibly warmer climate in the future.

description: Understanding the nature and hierarchy of on surface reactions is a major chal- lenge for designing coordination and covalent nanostructures by means of multistep synthetic routes. In particular, intermediates and final products are hard to predict since reaction paths and their activation windows depend on the choice of both the molecular precursor design and the substrate. Here we report a systematic study of the effect of the catalytic metal surface to reveal how a single precursor can give rise to very distinct polymers that range from coordination and covalent non planar polymer chains of distinct chirality, to atomically precise graphene nanoribbons and nanoporous graphene. Our precursor consists on adding two phenyl substituents to 10,10'-dibromo 9,9'-bianthracene, a well-studied precursor in the on-surface synthesis of graphene nanoribbons. The critical role of the monomer design on the reaction paths is inferred from the fact that the phenyl substitution leads to very distinct products in each one of the studied metallic substrates.

description: In the framework of the “Compact Light XLS” project, a short ultra-high gradient linearizer working on the third harmonic of the main linac frequency is requested. Increasing gradients and reducing dimensions are requirements for XLS and all next generation linear accelerators. Actually, ultracompact normal conducting accelerating structures, operating in the Ka-band regime ranging from 100 to 150 MV/m are required to achieve ultra-high gradients for research, industrial and medical applications. To fulfill these strong requirements, the R&D of a proper Ka-band klystron with RF power output and a high efficiency is mandatory. This contribution reports the design of a possible klystron amplifier tube operating on the TM010 mode at 36 GHz, the third harmonic of the 12 GHz linac frequency, with an efficiency of 42% and a 20 MW RF power output. This contribution discusses also the high-power DC gun, the beam focusing channel and the RF beam dynamics.

description: We develop a generic spacetime model in General Relativity which can be used to build any gravitational model within General Relativity. The generic model uses two types of assumptions: (a) Geometric assumptions additional to the inherent geometric identities of the Riemannian geometry of spacetime and (b) Assumptions defining a class of observers by means of their 4-velocity $u^{a}$ which is a unit timelike vector field. The geometric assumptions as a rule concern symmetry assumptions (the so called collineations). The latter introduces the 1+3 decomposition of tensor fields in spacetime. The 1+3 decomposition results in two major results. The 1+3 decomposition of $u_{a;b}$ defines the kinematic variables of the model (expansion, rotation, shear and 4-acceleration) and defines the kinematics of the gravitational model. The 1+3 decomposition of the energy momentum tensor representing all gravitating matter introduces the dynamic variables of the model (energy density, the isotropic pressure, the momentum transfer or heat flux vector and the traceless tensor of the anisotropic pressure) as measured by the defined observers and define the dynamics of he model. The symmetries assumed by the model act as constraints on both the kinematical and the dynamical variables of the model. As a second further development of the generic model we assume that in addition to the 4-velocity of the observers $u_{a}$ there exists a second universal vector field $n_{a}$ in spacetime so that one has a so called double congruence $(u_{a},n_{a})$ which can be used to define the 1+1+2 decomposition of tensor fields. The 1+1+2 decomposition leads to an extended kinematics concerning both fields building the double congruence and to a finer dynamics involving more physical variables.

description: The text analyses developments in international climate negotiations, highlighting COP 28 and its impact on the European Union and Africa. It highlights climate change as a political, economic and social threat, supported by the conclusions of the United Nations IPCC. The poorest nations, lacking financial and technological resources, face difficulties in mitigating the effects of climate change. Industrialised countries, despite their power, sometimes fail to meet their commitments. The notion of "climate justice" is emerging, advocating an equitable distribution of the means to combat climate change. Although there have been some successes in the global fight against climate change, ethical questions persist in terms of equality of opportunity. The research methodology explores international legal instruments and the opinions expressed. The first part examines the evolution of the negotiations up to COP 27, while the second looks at the European Union's contribution and its implications for Africa. Finally, the text highlights the importance of long-term climate data and interdisciplinarity in understanding the issues. Political decisions depend on the interactions between players, forces, lobbies and the media, which influence the fight against global warming.

description: The formation of supermassive stars (SMSs) is a possible pathway to seed supermassive black holes in the early universe. This chapter summarizes recent theoretical efforts to understand their evolution, highlighting effects of very rapid accretion at the rates of $\dot{M}_* \gtrsim 0.1~$M$_\odot$ yr$^{-1}$. Stellar evolution calculations predict that such an accreting SMS has a characteristic feature, i.e., a very large radius that monotonically increases as the stellar mass increases. The radius exceeds $7000$ R$_\odot$ (or $30$ AU) after the star accretes the gas of more than $10^3$ M$_\odot$. We show that the emergence of the "supergiant protostar" stage is a key for the formation of SMSs, because resulting radiative feedback against the accretion flow is substantially weakened during this stage. We also show that these SMSs end their lives while the accretion continues, and that their final fates vary with different accretion rates.

description: We study chiral partner structure of four light nucleons, $N(939)$, $N(1440)$, $N(1535)$ and $N(1650)$ using an effective chiral model based on the parity doublet structure. In our model we introduce four chiral representations, $({\bf 1},{\bf 2})$, $({\bf 2},{\bf 1})$, $({\bf 2},{\bf 3})$ and $({\bf 3},{\bf 2})$ under ${\rm SU}(2)_{\rm L} \otimes {\rm SU}(2)_{\rm R}$ symmetry. We determine the model parameters by fitting them to available experimental values of masses, widths and the axial charge of $N(939)$ together with the axial charges of $N(1535)$ and $N(1650)$ by lattice analyses. We find five groups of solutions: In a group the chiral partner to $N(939)$ is $N(1440)$ having small chiral invariant mass. In another group, the chiral partner is a mixture of $N(1535)$ and $N(1650)$ having a large chiral invariant mass. We claim that off-diagonal elements of axial-charge matrix can be used for distinguishing these groups. We also discuss changes of masses associated with chiral symmetry restoration, which could emerge in high density matter.

description: We point out that equivalence principle violations, while not dynamically equivalent, produce the same kinematical effects as Lorentz invariance violations for particle processes in a constant gravitational potential. This allows us to translate many experimental bounds on Lorentz invariance violations into bounds on equivalence principle violations. The most stringent bound suggests that a postive signal in an Eötvös experiment may be at least seven orders of magnitude beyond current technology.

description: On-device intelligence is gaining significant attention recently as it offers local data processing and low power consumption. In this research, an on-device training circuitry for threshold-current memristors integrated in a crossbar structure is proposed. Furthermore, alternate approaches of mapping the synaptic weights into fully-trained and semi-trained crossbars are investigated. In a semi-trained crossbar a confined subset of memristors are tuned and the remaining subset of memristors are not programmed. This translates to optimal resource utilization and power consumption, compared to a fully programmed crossbar. The semi-trained crossbar architecture is applicable to a broad class of neural networks. System level verification is performed with an extreme learning machine for binomial and multinomial classification. The total power for a single 4x4 layer network, when implemented in IBM 65nm node, is estimated to be ~ 42.16uW and the area is estimated to be 26.48um x 22.35um.

description: Direct and indirect searches of the Higgs boson suggest that 113 GeV $\lesssim m_H \lesssim$ 170 GeV is likely. With the LEP era over and the Tevatron Run II search via $p\bar p \to WH+X$ arduous, we revisit a case where $WH$ or $ZH +$ jets could arise via strong $b^\prime\bar b^\prime$ pair production. In contrast to 10 years ago, the tight electroweak constraint on $t^\prime$--$b^\prime$ (hence $t^\prime$--$t$) splitting reduces FCNC $b^\prime\to bZ$, $bH$ rates, making $b^\prime\to cW$ naturally competitive. Such a "cocktail solution" is precisely the mix that could evade the CDF search for $b^\prime\to bZ$, and the $b^\prime$ may well be lurking below the top. In light of the Higgs program, this two-in-one strategy should be pursued.

description: This is the first study on “presumed drylands”; lands with an aridity index higher than or equal to 0.65 and dryland features. It aims to describe the nature and extent of “presumed drylands” and their drivers and pressures of land degradation, current state, ongoing impacts, and land-management responses. We find that “presumed drylands” cover 10.75 million km2 (7% of the globe). Most “presumed drylands” are tropical and subtropical grassland biomes (58%), although the most frequent land use is forest (30%) and half of the area of “presumed drylands” (50%) contains trees. Land degradation in these areas is driven by regionally distinct biophysical and anthropogenic factors, compounded by climate change and extreme weather events. Responses implemented include agroforestry, sustainable land management, fire management, restoration, and protection. The scope and scale of ongoing degradation suggests that “presumed drylands” may become drylands. Hence, urgent investment in sustainable land management is needed.

description: We critically analyse the data available on the reduced cross-section in deeply inelastic $e p$ scattering from the H1 collaboration at HERA. We use available data on the longitudinal structure function to deduce the nature of $\d F_2/\d\ln Q^2$ at different $Q^2$ for fixed values of $x$ near $x \sim 10^{-4}$. We present the results in a manner which effectively isolates possible higher twist effects in the structure function $F_2$.

Dark Energy in the Swampland

description: In this Letter, we study the implications of string Swampland criteria for dark energy in view of ongoing and future cosmological observations. If string theory should be the ultimate quantum gravity theory, there is evidence that exact de Sitter solutions with a positive cosmological constant cannot describe the fate of the late-time universe. Even though cosmological models with dark energy given by a scalar field $π$ evolving in time are not in direct tension with string theory, they have to satisfy the Swampland criteria $|Δπ|c\sim\mathcal{O}(1)$, where $V$ is the scalar field potential. In view of the restrictive implications that the Swampland criteria have on dark energy, we investigate the accuracy needed for future observations to tightly constrain standard dark-energy models. We find that current 3-$σ$ constraints with $c \lesssim 1.35$ are still well in agreement with the string Swampland criteria. However, Stage-4 surveys such as Euclid, LSST and DESI, tightly constraining the equation of state $w(z)$, will start putting surviving quintessence models into tensions with the string Swampland criteria by demanding $c<0.4$. We further investigate whether any idealised futuristic survey will ever be able to give a decisive answer to the question whether the cosmological constant would be preferred over a time-evolving dark-energy model within the Swampland criteria. Hypothetical surveys with a reduction in the uncertainties by a factor of $\sim20$ compared to Euclid would be necessary to reveal strong tension between quintessence models obeying the string Swampland criteria and observations by pushing the allowed values down to $c<0.1$. In view of such perspectives, there will be fundamental observational limitations with future surveys.

Precise depth measurements are the basis for creating high resolution models of the sea surface. The morphology of the seabed, interpreted from bathymetric models, gives information about the geological processes on the earth surface.

description: The spontaneous vacuum magnetization at finite temperature is investigated in SU(2) gluodynamics within a consistent effective potential approach including the one-loop and the correlation correction contributions. To evaluate the latter ones the high temperature limits of the polarization operators of charged and neutral gluon fields in a covariantly constant magnetic field and at high temperature are calculated.The radiation mass squared of charged gluons is found to be positive. It is shown that the ferromagnetic vacuum state having a field strength of order $(gH)^{1/2} \sim g^{4/3} T$ is spontaneously generated at high temperature. The vacuum stability and some applications of the results obtained are discussed.

 Distribution. São Paulo, Brazil; San Pedro, Paraguay (Fig. 1).
 Remarks. The species is known from the type specimen only. The original description assigns the “author’s collection” as repository (Arlé 1947), which would be the Museu Nacional, in Rio de Janeiro, Brazil. The curator (Felipe Vivallo), however, confirmed that the holotype of A. irmgardae was not deposited at the Museu Nacional. Arlé worked at Museu Paraense Emílio Goeldi from 1962 to 1972 (Overal & Gorayeb 1981), after the description date, but the curator (Orlando Silveira) also confirmed the absence of the holotype. Because the holotype could not be located, and following the description of Arlé (1947), we designate the specimen examined for the current paper as the neotype of A. irmgardae. See Arlé (1947) for detail description.

Analyzing Uncertainty Matrices Associated with Multiple S-parameter Measurements

description: This paper presents a detailed analysis of uncertainty matrices (i.e. measurement covariance matrices) associated with multiple complex-valued microwave scattering S-parameter measurements. The analysis is based on forming combinations of (2 X 2) sub-matrices from selected elements in the uncertainty matrix and using these sub-matrices to define uncertainty ellipses in two-dimensional measurement planes. These uncertainty ellipses can be used to assess the quality, accuracy and validity of the measurements. A simple example is given using measurements made on a waveguide mismatched line section at frequencies from 75 GHz to 110 GHz. The analysis is also useful when multiple S-parameter measurements are used as input quantities for measurement models used to determine other measurement quantities (i.e. as output quantities).
