description: We present the measurements of the luminosity-dependent redshift-space three-point correlation functions (3PCFs) for the Sloan Digital Sky Survey (SDSS) DR7 Main galaxy sample. We compare the 3PCF measurements to the predictions from three different halo and subhalo models. One is the halo occupation distribution (HOD) model and the other two are extensions of the subhalo abundance matching (SHAM) model by allowing the central and satellite galaxies to have different occupation distributions in the host halos and subhalos. Parameters in all the models are chosen to best describe the projected and redshift-space two-point correlation functions (2PCFs) of the same set of galaxies. All three model predictions agree well with the 3PCF measurements for the most luminous galaxy sample, while the HOD model better performs in matching the 3PCFs of fainter samples (with luminosity threshold below $L^*$), which is similar in trend to the case of fitting the 2PCFs. The decomposition of the model 3PCFs into contributions from different types of galaxy triplets shows that on small scales the dependence of the 3PCFs on triangle shape is driven by nonlinear redshift-space distortion (and not by the intrinsic halo shape) while on large scales it reflects the filamentary structure. The decomposition also reveals more detailed differences in the three models, which are related to the radial distribution, the mean occupation function, and the velocity distribution of satellite galaxies inside halos. The results suggest that galaxy 3PCFs can further help constrain the above galaxy-halo relation and test theoretical models.

description: We investigate superconducting interference device (SQUID) with two asymmetric Josephson junctions coupled to a mechanical resonator embedded in the loop of the SQUID. We quantize this system in the case when the frequency of the mechanical resonator is much lower than the cavity frequency of the SQUID and in the case when they are comparable. In the first case, the radiation pressure and cross-Kerr type interactions arise and are modified by asymmetry. Cross-Kerr type coupling is the leading term at the extremum points where radiation pressure is zero. In the second case, the main interaction is single-photon beam splitter, which exists only at finite asymmetry. Another interaction in this regime is of cross-Kerr type, which exists at all asymmetries, but generally much weaker than the beam splitter interaction. Increasing magnetic field can substantially enhance optomechanical couplings strength with the potential for the radiation pressure coupling to reach the single-photon strong coupling regime, even the ultrastrong coupling regime, in which the single-photon coupling rate exceeds the mechanical frequency.

description: For the recent GW100 test set of molecular ionization energies, we present a comprehensive assessment of different GW methodologies: fully self-consistent GW (scGW), quasiparticle self-consistent GW (qsGW), partially self-consistent GW0 (scGW0), perturbative GW (G0W0) and optimized G0W0 based on the minimization of the deviation from the straight-line error (DSLE-minimized GW). We compare our GW calculations to coupled-cluster singles, doubles, and perturbative triples [CCSD(T)] reference data for GW100. We find scGW and qsGW ionization energies in excellent agreement with CCSD(T), with discrepancies typically smaller than 0.3 eV (scGW) respectively 0.2 eV (qsGW). For scGW0 and G0W0 the deviation from CCSD(T) is strongly dependent on the starting point. We further relate the discrepancy between the GW ionization energies and CCSD(T) to the deviation from straight line error (DSLE). In DSLE-minimized GW calculations, the DSLE is significantly reduced, yielding a systematic improvement in the description of the ionization energies.

description: Using the type II seesaw approach and properties of discrete flavor symmetry group representations, we build a supersymmetric $A_{4}\times A_{3}$\ neutrino model with $θ_{13}\neq0$. After describing the basis of this model--which is beyond the minimal supersymmetric Standard Model--with a superfield spectrum containing flavons in $A_{4}\times A_{3}$\ representations, we first generate the tribimaximal neutrino mixing which is known to be in agreement with the mixing angles $θ_{12}$ and $θ_{23}$. Then, we give the scalar potential of the theory where the $A_{3}$ discrete subsymmetry is used to avoid the so-called sequestering problem. We \textrm{next} study the deviation from the tribimaximal mixing matrix which is produced by perturbing the neutrino mass matrix with a nontrivial $A_{4}$ singlet. Normal and inverted mass hierarchies are discussed numerically. We also study the breaking of $A_{4}$\ down to $Z_{3}$\ in the charged lepton sector, and use the branching ratio of the decay $τ\rightarrow μμe$--which is allowed by the residual symmetry $Z_{3}$--to get estimations on the mass of one of the flavons and the cutoff scale $Λ$ of the model.

description: Employing the so-called hybrid formalism, we calculate the cross section of inclusive hadron production in proton-proton collisions at forward rapidity in small-$x$ formalism at one-loop order. For the case of hadron production at forward rapidity, we can uses collinear parton distributions for projectile proton and $k_\perp$ dependent gluon distribution for target proton. We show that collinear divergences associated with initial and final state parton radiations are renormalized into parton distributions and fragmentation functions in terms of the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equation, respectively. Furthermore, rapidity divergence can be absorbed into the wave function of target proton which gives rise to the well-known Balitsky-Fadin-Kuraev-Lipatov equation. These divergences are completely separated from the short distance partonic hard parts, which is now finite at the next-to-leading order accuracy. The result presented in this paper can be reckoned as a baseline calculation without any non-linear QCD effects in small-$x$ formalism. As a consistency check, we compare our results with the previous calculation for non-linear proton-nucleus collisions in the small-$x$ formalism and find complete agreement in the dilute and large $N_c$ limit. In phenomenology, the direct comparison of the above two separate calculations can reveal the role and strength of the non-linear dynamics in high energy QCD, and thus help us reliably study the onset of gluon saturation when genuine non-linear interactions become important.

On the Diversity of Compact Objects within Supernova Remnants II: Energy Loss Mechanisms

description: Energy losses from isolated neutron stars are commonly attributed to the emission of electromagnetic radiation from a rotating point-like magnetic dipole in vacuum. This emission mechanism predicts a braking index $n=3$, which is not observed in highly magnetized neutron stars. Despite this fact, the assumptions of a dipole field and rapid early rotation are often assumed a priori, typically causing a discrepancy between the characteristic age and the associated supernova remnant (SNR) age. We focus on neutron stars with `anomalous' magnetic fields that have established SNR associations and known ages. Anomalous X-ray pulsars (AXPs) and soft gamma repeaters (SGRs) are usually described in terms of the magnetar model, which posits a large magnetic field established by dynamo action. The high magnetic field pulsars (HBPs) have extremely large magnetic fields just above QED scale (but below that of the AXPs and SGRs), and central compact objects (CCOs) may have buried fields that will emerge in the future as nascent magnetars. In the first part of this series we examined magnetic field growth as a method of uniting the CCOs with HBPs and X-ray dim isolated neutron stars (XDINSs) through evolution. In this work we constrain the characteristic age of these neutron stars using the related SNR age for a variety of energy loss mechanisms and allowing for arbitrary initial spin periods. In addition to the SNR age, we also make use of the observed braking indices and X-ray luminosities to constrain the models.

description: Ultraviolet (UV) wavelength observations have made a significant contribution to our understanding of hot stellar populations of star clusters. Multi-wavelength spectral energy distributions (SEDs) of stars, including ultraviolet observations, have proven to be an excellent tool for discovering unresolved hot companions in exotic stars such as blue straggler stars (BSS), thereby providing helpful clues to constrain their formation mechanisms. Melotte 66 is a 3.4 Gyr old open cluster located at a distance of 4810 pc. We identify the cluster members by applying the ML-MOC algorithm on Gaia EDR3 data. Based on our membership identification, we find 1162 members, including 14 BSS candidates, 2 yellow straggler candidates (YSS), and one subdwarf B candidate (sdB). We generated SEDs for 11 BSS candidates and the sdB candidate using Swift/UVOT data combined with other archival data in the optical and IR wavelengths. We discover a hot companion of one BSS candidate, BSS3, with temperature of 38000$_{-6000}^{+7000}$ K, luminosity of 2.99$_{-1.86}^{+5.47}$ L$_\odot$, and radius of 0.04$_{-0.005}^{+0.008}$ R$_\odot$. This hot companion is a likely low-mass WD with an estimated mass of 0.24 $\text{-}$ 0.44 M$_\odot$. We report one BSS candidate, BSS6, as an Algol-type eclipsing binary with a period of 0.8006 days, based on the Gaia DR3 variability classification. We suggest that BSS3 is formed via either the Case A or Case B mass-transfer channel, whereas BSS6 is formed via the Case A mass transfer.

Local Operators in Kinetic Wealth Distribution

description: The statistical mechanics approach to wealth distribution is based on the conservative kinetic multi-agent model for money exchange, where the local interaction rule between the agents is analogous to the elastic particle scattering process. Here, we discuss the role of a class of conservative local operators, and we show that, depending on the values of their parameters, they can be used to generate all the relevant distributions. We also show numerically that in order to generate the power-law tail an heterogeneous risk aversion model is required. By changing the parameters of these operators one can also fine tune the resulting distributions in order to provide support for the emergence of a more egalitarian wealth distribution.

description: It is well known that optical media create artificial geometry for light, and curved geometry acts as an effective optical medium. This correspondence originates from the form invariance of Maxwells equations, which recently has spawned a booming field called transformation optics. Here we investigate responses of three transformation media under electromagnetic pulses, and find that pulse radiation can induce unbalanced net force on transformation media, which will cause translation and rotation of transformation media although their final momentum can still be zero. Therefore, the transformation media do not necessarily stay the same after an electromagnetic wave passes through.

description: Stars that are collapsing toward forming a black hole but appear frozen near their Schwarzschild horizon are termed "black stars". The collision of two black stars leads to gravitational radiation during the merging phase followed by a delayed gamma ray burst during coalescence. The recent observation of gravitational waves by LIGO, followed by a possible gamma ray counterpart by Fermi, suggests that the source may have been a merger of two black stars with profound implications for quantum gravity and the nature of black holes.

description: In this work, we investigate an efficient numerical approach for solving higher order statistical methods for blind and semi-blind signal recovery from non-ideal channels. We develop numerical algorithms based on convex optimization relaxation for minimization of higher order statistical cost functions. The new formulation through convex relaxation overcomes the local convergence problem of existing gradient descent based algorithms and applies to several well-known cost functions for effective blind signal recovery including blind equalization and blind source separation in both single-input-single-output (SISO) and multi-input-multi-output (MIMO) systems. We also propose a fourth order pilot based cost function that benefits from this approach. The simulation results demonstrate that our approach is suitable for short-length packet data transmission using only a few pilot symbols.

description: Galactic nuclei, like the one of the Milky Way, are extreme places with high stellar densities and, in most cases, hosting a supermassive black hole. One of the scenarios proposed for the formation of the Galactic nucleus is by merging of primordial globular clusters (Capuzzo-Dolcetta 1993). An implication of this model is that this region should host stars characteristically found in old Milky Way globular clusters. RR Lyrae stars are primary distance indicators, well known representatives of old and metal-poor stellar populations, and therefore regularly found in globular clusters. Here we report the discovery of a dozen RR Lyrae ab-type stars in the vicinity of the Galactic center, i.e. in the so-called nuclear stellar bulge of the Milky Way. This discovery provides the first direct observational evidence that the Galactic nuclear stellar bulge contains ancient stars (>10 Gyr old). Based on this we conclude that merging globular clusters likely contributed to building-up the high stellar density in the nuclear stellar bulge of the Milky Way.

description: The paper analyzes the specificities of Serbia’s response to the coronavirus. The two most important issues during the pandemic were the role of the State and the management of migration flows. Being placed in the China–Russia–EU triangle shaped the response on the crises and the image of the country in the world. Two phenomena shaped mobility patterns. Citizens returning from abroad were caught between accusations of spreading the virus and a plea for healthcare and other vital workers from the Serbian diaspora to help in Serbia. The issue of refugees and migrants attracted significant amounts of positive public attention, but in parallel with that xenophobia arose as a new attitude as part of aggressive campaigns against them.

description: We introduce and analyze a linear kinetic model that describes the evolution of the probability density of the number of firms in a society, in which the microscopic rate of change obeys to the so-called law of proportional effect proposed by Gibrat. Despite its apparent simplicity, the possible mean field limits of the kinetic model are varied. In some cases, the asymptotic limit can be described by a first-order partial differential equation. In other cases, the mean field equation is a linear diffusion with a non constant diffusion coefficient that models also the geometric Brownian motion and can be studied analytically. In this case, it is shown that the large-time behavior of the solution is represented, for a large class of initial data, by a lognormal distribution with constant mean value and variance increasing exponentially in time at a precise rate. The relationship between the kinetic and the diffusion models allow to introduce an easy-to- implement expression for computing the Fourier transform of the lognormal distribution.

description: Over the last decades, superconducting nanowires have developed from a playground for fundamental research to a promising key element for various applications, including superinductors, qubits or quantum transistors. The wide range of electrical properties is due to the quantum phase slip (QPS) effect, a process during which the phase of the superconducting order parameter can slip by 2$\pi$. Each phase slip can be associated with a fluxon tunneling across the wire and therefore be seen as the dual to the tunneling of Cooper pairs in Josephson junctions. Depending on the QPS amplitude, the electrical response of a wire can range from a purely inductive to a capacitive one. In particular, the duality between these phase slip junctions and Josephson junctions, which have become a basic building block of modern quantum circuits, has triggered a variety of theoretical and experimental works. Many aspects of these fluctuations are still not fully understood. Furthermore, the parameter spread of the nanowires' properties turned out to be a limiting factor for experimental implementations, especially when more than one wire is involved. In this work, we investigate quantum phase slips in nanowires made from granular aluminum. We demonstrate that the normal state resistance of single wires can be reduced by orders of magnitude, using the newly developed method "intrinsic electromigration". With this new degree of freedom, we are able to study the influence of the phase slip amplitude on the transport behaviour of a wire and compare it with microscopic theories. Special attention is put on the phase slip driven superconductor to insulator transition (SIT). To probe the coherent nature of quantum phase slips and to further investigate the SIT, we developed a quantum phase slip interferometer based on two strongly coupled wires connected in series. The interference pattern is controlled by a gate voltage and manifests as a periodic modulation of the critical Coulomb blockade voltage. For strong, destructive interference of quantum phase slips, a transition from the insulating to a superconducting state is observed. The simple design of the device as well as the large available parameter range make it an interesting device also for applications beyond fundamental research like e.g a transistor for information processing, a particle detector or as a nonlinear capacitor.

description: HIGEE (an acronym of high gravity) devices have attracted considerable attention among the researchers due to its immense process intensification capability. In order to achieve desired process efficiency this technology replaces terrestrial acceleration by centrifugal one (typically 1000g) which can be attained by rotating a specially shaped rigid bed. This study focuses on liquid–liquid extraction of hexavalent chromium [Cr(VI)] from wastewater using aliquat-336 as an extractant inside a novel rotating zigzag contactor (RZC). Extraction efficiency of RZC were observed with the variation in pH (2–10), rotational speed (300–1100rpm), aqueous phase (0.4–1.2 L-min−1) and organic phase (0.05–0.15 L-min−1) flow rate, feed (25–200 mg-L−1) and extractant (0.5–1.25 vol%) concentration. The results obtained from this study showed a significant improvement in extraction efficiency (85–99%) with the variation in rotational speed (300–1100rpm). It was observed that the efficiency increased with rotational speed, total flow rate and the organic phase flow rates but decreased with the feed concentration and pH of the aqueous solution. Comparison with some conventional contactors reveals that the extraction efficiency obtained in RZC was nearly 40–50% higher under the same operating conditions.

description: I propose that most problems about circles (cycles, circuits) in ordinary graphs that have odd or even length find their proper setting in the theory of signed graphs, where each edge has a sign, $+$ or $-$. Even-circle and odd-circle problems correspond to questions about positive and negative circles in signed graphs. (The sign of a circle is the product of its edge signs.) I outline questions about circles in signed graphs, that seem natural and potentially important.

description: A Educação a Distância, em Portugal, como noutros países, tem vindo a expandir-se graças ao desenvolvimento tecnológico das duas últimas décadas, colocando novos desafios sobre os quais importa refletir. Neste sentido, este artigo focaliza-se na Educação a Distância e, embora centrado na atualidade, não olvida os antecedentes e a trajetória evolutiva até à apropriação das tecnologias no ensino e na aprendizagem, indispensáveis à modalidade on-line e ao e-learning. Na procura da estabilização do conceito de educação a distância e com a perspetiva de o operacionalizar, evidenciam-se os pilares que o suportam dissecando os seus referentes. Ao confinar o contexto de análise a Portugal, apontam-se as suas origens com a indicação dos marcos significativos ao seu desenvolvimento e referem-se as diferentes gerações que se foram sucedendo e provocando profundas alterações na educação a distância, ao longo das últimas décadas. Ilustra-se, entretanto, o caso da Universidade Aberta por ser a única instituição de ensino superior que expressa esta modalidade de ensino no diploma da sua fundação e a primeira a criar e aplicar um modelo pedagógico radicado nesta modalidade de ensino. Ao concluir, serão feitas considerações gerais sobre a educação a distância na atualidade, seguindo uma matriz reflexiva e questionante que visa a relevância da sua dimensão pedagógica mais propriamente na exigência inovadora das suas didáticas.

description: We introduce a new family of $N\times N$ random real symmetric matrix ensembles, the $k$-checkerboard matrices, whose limiting spectral measure has two components which can be determined explicitly. All but $k$ eigenvalues are in the bulk, and their behavior, appropriately normalized, converges to the semi-circle as $N\to\infty$; the remaining $k$ are tightly constrained near $N/k$ and their distribution converges to the $k \times k$ hollow GOE ensemble (this is the density arising by modifying the GOE ensemble by forcing all entries on the main diagonal to be zero). Similar results hold for complex and quaternionic analogues. We isolate the two regimes by using matrix perturbation results and a nonstandard weight function for the eigenvalues, then derive their limiting distributions using a modification of the method of moments and analysis of the resulting combinatorics.

Why is the Abwehr misunderstood? Explaining the historical controversy over German military intelligence, 1935-1945

description: Literature on German resistance and its central actor, the Abwehr (German military intelligence), during the Nazi regime is in abundance available, but no universally accepted history of the Abwehr and its leadership exist. Vehement controversies are found in historical literature regarding the Abwehr’s and its leadership’s aims, motives, roles and performance, its support for the Allied war efforts and its influence on the war’s outcome. By reading through literature, one finds that the Abwehr is misunderstood due to narrow views, social and political circumstance, political gains, intellectual snobbery and preconceived opinions about intelligence and classes. Several factors contribute to the mishandling of facts by historians and the misinterpretation of the Abwehr. Historians’ inadequate engagement with the complex and contradictory double-role of the Abwehr as intelligence organization and simultaneously as centre of resistance and the refusal among British historians to acknowledge intelligence cooperation between enemies and the Abwehr’s support of the Allied war efforts, indicating British intelligence supremacy, lead to the grave contradictions in literature. A critical evaluation of different strands in the history of WWII is presented, enabling the development of a more historically grounded and broadly contextualized perspective through profound engagement with the literature. By considering availability and choice of resources, the influence of social, cultural, political, intellectual and personal factors on historian’s interpretation, the thesis contributes to the understanding of the dynamics of the historiography of the Abwehr and exposes the reasons for misinterpretations, thereby contributing to history’s intellectual history, epistemology, and craft.
