description: Magnetic resonance (MR) image acquisition is an inherently prolonged process, whose acceleration has long been the subject of research. This is commonly achieved by obtaining multiple undersampled images, simultaneously, through parallel imaging. In this paper, we propose the Dual-Octave Network (DONet), which is capable of learning multi-scale spatial-frequency features from both the real and imaginary components of MR data, for fast parallel MR image reconstruction. More specifically, our DONet consists of a series of Dual-Octave convolutions (Dual-OctConv), which are connected in a dense manner for better reuse of features. In each Dual-OctConv, the input feature maps and convolutional kernels are first split into two components (ie, real and imaginary), and then divided into four groups according to their spatial frequencies. Then, our Dual-OctConv conducts intra-group information updating and inter-group information exchange to aggregate the contextual information across different groups. Our framework provides three appealing benefits: (i) It encourages information interaction and fusion between the real and imaginary components at various spatial frequencies to achieve richer representational capacity. (ii) The dense connections between the real and imaginary groups in each Dual-OctConv make the propagation of features more efficient by feature reuse. (iii) DONet enlarges the receptive field by learning multiple spatial-frequency features of both the real and imaginary components. Extensive experiments on two popular datasets (ie, clinical knee and fastMRI), under different undersampling patterns and acceleration factors, demonstrate the superiority of our model in accelerated parallel MR image reconstruction.

description: A combination of experimental techniques and molecular dynamics (MD) computer simulation is used to investigate the diffusion dynamics in Al80Ni20 melts. Experimentally, the self-diffusion coefficient of Ni is measured by the long-capillary (LC) method and by quasielastic neutron scattering. The LC method yields also the interdiffusion coefficient. Whereas the experiments were done in the normal liquid state, the simulations provided the determination of both self-diffusion and interdiffusion constants in the undercooled regime as well. The simulation results show good agreement with the experimental data. In the temperature range 3000 K >= T >= 715 K, the interdiffusion coefficient is larger than the self-diffusion constants. Furthermore the simulation shows that this difference becomes larger in the undercooled regime. This result can be refered to a relatively strong temperature dependence of the thermodynamic factor Φ, which describes the thermodynamic driving force for interdiffusion. The simulations also indicate that the Darken equation is a good approximation, even in the undercooled regime. This implies that dynamic cross correlations play a minor role for the temperature range under consideration.

description: Given a set $S$ of $n$ distinct keys, a function $f$ that bijectively maps the keys of $S$ into the range $\{0,\ldots,n-1\}$ is called a minimal perfect hash function for $S$. Algorithms that find such functions when $n$ is large and retain constant evaluation time are of practical interest; for instance, search engines and databases typically use minimal perfect hash functions to quickly assign identifiers to static sets of variable-length keys such as strings. The challenge is to design an algorithm which is efficient in three different aspects: time to find $f$ (construction time), time to evaluate $f$ on a key of $S$ (lookup time), and space of representation for $f$. Several algorithms have been proposed to trade-off between these aspects. In 1992, Fox, Chen, and Heath (FCH) presented an algorithm at SIGIR providing very fast lookup evaluation. However, the approach received little attention because of its large construction time and higher space consumption compared to other subsequent techniques. Almost thirty years later we revisit their framework and present an improved algorithm that scales well to large sets and reduces space consumption altogether, without compromising the lookup time. We conduct an extensive experimental assessment and show that the algorithm finds functions that are competitive in space with state-of-the art techniques and provide $2-4\times$ better lookup time.

The Formation of Globular Cluster Systems in Massive Elliptical Galaxies: Globular Cluster Multimodality from Radial Variation of Stellar Populations

description: The most massive elliptical galaxies show a prominent multi-modality in their globular cluster system color distributions. Understanding the mechanisms which lead to multiple globular cluster sub-populations is essential for a complete picture of massive galaxy formation. By assuming that globular cluster formation traces the total star formation and taking into account the radial variations in the composite stellar populations predicted by the Pipino & Matteucci (2004) multi-zone photo-chemical evolution code, we compute the distribution of globular cluster properties as a function of galactocentric radius. We compare our results to the spectroscopic measurements of globular clusters in nearby early-type galaxies by Puzia et al. (2006) and show that the observed multi-modality in globular cluster systems of massive ellipticals can be, at least partly, ascribed to the radial variation in the mix of stellar populations. Our model predicts the presence of a super-metal-rich population of globular clusters in the most massive elliptical galaxies, which is in very good agreement with the spectroscopic observations. Furthermore, we investigate the impact of other non-linear mechanisms that shape the metallicity distribution of globular cluster systems, in particular the role of merger-induced globular cluster formation and a non-linear color-metallicity transformation, and discuss their influence in the context of our model (abridged)

description: The modified Kadomtsev-Petviashvili (mKP) equation is shown in this paper to be decomposable into the first two soliton equations of the 2N-coupled Chen-Lee-Liu and Kaup-Newell hierarchies by respectively nonlinearizing two sets of symmetry Lax pairs. In these two cases, the decomposed (1+1)-dimensional nonlinear systems both have a couple of different Lax representations, which means that there are two linear systems associated with the mKP equation under the same constraint between the potential and eigenfunctions. For each Lax representation of the decomposed (1+1)-dimensional nonlinear systems, the corresponding Darboux transformation is further constructed such that a series of explicit solutions of the mKP equation can be recursively generated with the assistance of symbolic computation. In illustration, four new families of solitary-wave solutions are presented and the relevant stability is analyzed.

description: We identified and computed the horizontal wavelengths of atmospheric gravity waves in clouds using a visible camera installed on a window of the Columbus module of the International Space Station (ISS) and controlled by a Raspberry Pi computer. The experiment was designed in the context of the Astro Pi challenge, a project run by ESA in collaboration with the Raspberry Pi Foundation, where students are allowed the opportunity to write a code to be executed at the ISS. A code was developed to maximize the probability of capturing images of clouds while the ISS is orbiting the Earth. Several constraints had to be fulfilled such as the experiment duration limit (3 hours) and the maximum data size (3 gigabytes). After receiving the data from the ISS, small-scale gravity waves were observed in different regions in the northern hemisphere with horizontal wavelengths in the range of 1.0 to 4.7 km.

I 344 (2007), 21-26.] and some description of automorphisms of rational surfaces. Given a finite Abelian subgroup of the Cremona group of the plane, we provide a way to decide whether it is birationally conjugate to a group of automorphisms of a minimal surface. In particular, we prove that a finite cyclic group of birational transformations of the plane is linearisable if and only if none of its non-trivial elements fix a curve of positive genus. For finite Abelian groups, there exists only one surprising exception, a group isomorphic to Z/2ZxZ/4Z, whose non-trivial elements do not fix a curve of positive genus but which is not conjugate to a group of automorphisms of a minimal rational surface. We also give some descriptions of automorphisms (not necessarily of finite order) of del Pezzo surfaces and conic bundles.

Running mass of the b-quark in QCD and SUSY QCD

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The running mass of the b-quark defined in DRbar-scheme is one of the important parameters of SUSY QCD. To find its value it should be related to some known experimental input. In this paper the b-quark running mass defined in nonsupersymmetric QCD is chosen for determination of corresponding parameter in SUSY QCD. The relation between these two quantities is found by considering five-flavor QCD as an effective theory obtained from its supersymmetric extension. A numerical analysis of the calculated two-loop relation and its impact on the MSSM spectrum is discussed. Since for nonsupersymmetric models MSbar-scheme is more natural than DRbar, we also propose a new procedure that allows one to calculate relations between MSbar- and DRbar-parameters. Unphysical epsilon-scalars that give rise to the difference between mentioned schemes are assumed to be heavy and decoupled in the same way as physical degrees of freedom. By means of this method it is possible to ``catch two rabbits'', i.e., decouple heavy particles and turn from DRbar to MSbar, at the same time. Explicit two-loop example of DRbar -> MSbar transition is given in the context of QCD. The advantages and disadvantages of the method are briefly discussed.

description: (Abridged) We present a study of the optical spectra of a sample of eight star-forming nuclear rings and the nuclei of their host galaxies. The spectra were obtained with the ISIS spectrograph on the William Herschel Telescope and cover a wide range in wavelength, enabling the measurement of several stellar absorption features and gas emission lines. We compared the strength of the absorption lines to a variety of population synthesis models for the star-formation history in the nuclear rings, including also the contribution of the older bulge and disc stellar components. We find that the stars in our sample of nuclear rings have most likely formed over a prolonged period of time characterised by episodic bursts of star-formation activity. Constant star formation is firmly ruled out by the data, whereas a one-off formation event is an unlikely explanation for a common galactic component such as nuclear rings. We have used emission-line measurements to constrain the physical conditions of the ionised gas within the rings. Emission in all nuclear rings originates from HII-regions with electron densities typical for these kinds of objects, and that the rings are characterised by values for the gas metallicity ranging from slightly below to just above solar. As 20% of nearby spiral galaxies hosts nuclear rings that are currently forming massive stars, our finding of an episodic star formation history in nuclear rings implies that a significant population remains to be identified of young nuclear rings that are not currently in a massive star formation phase.

description: Recently, the ATLAS and CMS Collaborations reported the latest experimental upper limits on the branching ratios of the lepton flavor violating (LFV) 125 GeV Higgs boson decays, $h\rightarrow eμ$, $h\rightarrow eτ$, and $h\rightarrow μτ$. In this paper, we mainly investigate the LFV Higgs boson decays $h\rightarrow eμ$, $h\rightarrow eτ$, and $h\rightarrow μτ$ in the minimal supersymmetric extension of the Standard Model with local $\emph{B-L}$ gauge symmetry. At the same time, the corresponding constraints from the LFV rare decays $μ\rightarrow eγ$, $τ\rightarrow eγ$, $τ\rightarrow μγ$, and muon $(g-2)$ are considered to analyze the numerical results.

Transmission of kalilo DNA in senescent strains of Neurospora intermedia
Creators: name: Myers, Carolyn J.
Publisher: name: University of British Columbia
Year: 2010

description: Senescence, the progressive loss of growth potential culminating in death, is common among Kauaian strains of Neurospora intermedia. Senescence is initiated by the insertion of kalilo DNA into the mitochondrial DNA. Mitochondrial DNA molecules carrying the insert accumulate and death occurs when the insert is equimolar with the mitochondrial DNA. The inserted form of kalilo DNA is referred to as mtlS-kalDNA. Studies on the somatic transmission of mtlS-kalDNA in ascospore series have revealed that kalilo DNA is capable of assuming new locations within the mitochondrial DNA. It is proposed that these novel insertions originate from intramitochondrial movement and an autonomous form of kalilo DNA, mtFF-kalDNA, is predicted to be an intermediate in movement. Novel insertion of kalilo DNA appears to depend on the form of mtlS-kalDNA transmitted sexually. If a mutagenic insert is transmitted, senescence is initiated at the onset of vegetative growth of the ascospores and no novel insertions are detected. The lifespans of these ascospores are quite short, death occurring in 10 subcultures or less. Transmission of a nonmutagenic insert delays the onset of senescence until either a novel insertion or a rearrangement of the transmitted insert occurs. The lifespans of these ascospores usually exceed 10 subcultures and are variable. Information obtained from tetrad analysis has revealed that novel insertion of kalilo DNA may also be under the influence of the host genome. A senescent Kauaian strain was identified which shows some but not all characteristics of kalilo senescence. In this strain and its derivatives, the behaviour of mtlS-kalDNA is erratic and in, some cultures the characteristic mitochondrial biochemical deficiencies, normally accompanying kalilo senescence, are not observed. It is suspected that kalDNA is not responsible for senescence in this strain and its derivatives but rather some other unknown factor is affecting the normal growth patterns of these cultures. Kauaian strains were surveyed for the presence of dsRNA to determine whether kalDNA has a viral origin. Only one senescent strain contains detectable amounts of dsRNA which was not homologous with a kalDNA probe. The survey identified six nonKauaian strains which contain dsRNA and seven dsRNA species were delineated. Although the presence of dsRNA is not relevant to kalilo senescence, analysis of dsRNA in a genetically-well defined organism like Neurospora may give insight into the significance of dsRNA in fungi in general.
How to use the Scuba Diving metaphor to solve problem with neutrality ?

description: We proposed a new search heuristic using the scuba diving metaphor. This approach is based on the concept of evolvability and tends to exploit neutrality which exists in many real-world problems. Despite the fact that natural evolution does not directly select for evolvability, the basic idea behind the scuba search heuristic is to explicitly push evolvability to increase. A comparative study of the scuba algorithm and standard local search heuristics has shown the advantage and the limitation of the scuba search. In order to tune neutrality, we use the NKq fitness landscapes and a family of travelling salesman problems (TSP) where cities are randomly placed on a lattice and where travel distance between cities is computed with the Manhattan metric. In this last problem the amount of neutrality varies with the city concentration on the grid ; assuming the concentration below one, this TSP reasonably remains a NP-hard problem.

description: A mesoporous bioactive glass (MBG) of molar composition 75SiO2-20CaO-5P2O5 (MBG-75S) has been synthetized as a potential bioceramic for bone regeneration purposes. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), nitrogen adsorption studies and transmission electron microscopy (TEM) demonstrated that MBG-75Spossess a highly ordered mesoporous structure with high surface area and porosity, which would explain the high ionic exchange rate (mainly calcium and silicon soluble species) with the surrounded media. MBG-75S showed high biocompatibility in contact with Saos-2 osteoblast-like cells. Concentrations up to 1 mg/ml did not lead to significant alterations on either morphology or cell cycle. Regarding the effects on osteoclasts, MBG-75S allowed the differentiation of RAW-264.7 macrophages into osteoclast-like cells but exhibiting a decreased resorptive activity. These results point out that MBG-75S does not inhibit osteoclastogenesis but reduces the osteoclast boneresorbing capability. Finally, in vitro studies focused on the innate immune response, evidenced that MBG-75S allows the proliferation of macrophages without inducing their polarization towards the M1 pro-inflammatory phenotype. This in vitro behavior is indicative that MBG-75S would just induce the required innate immune response without further inflammatory complications under in vivo conditions. The overall behavior respect to osteoblasts, osteoclasts and macrophages, makes this MBG a very interesting candidate for bone grafting applications in osteoporotic patients.

Sleeping our way into replacing short-haul flights –studies of modal shift from short-haul flights to overnight sleeper services

description: Air transport plays an essential role in Europe’s short-haul passenger transport. However, air transport contributed nearly 14% of greenhouse gas emissions of all transport modes in the European Union. Meanwhile, the transport sector must meet the increasing demand for short-haul passenger transport. Based on railway transport’s better environmental performance and overnight railway sleeper’s advantages on leveraging sleeping hours into efficient travel times, this thesis studies the potential modal shift from short-haul flights to overnight railway sleepers. By analyzing both the number of passengers for Europe’s national and intra-Europe flights and existing overnight sleeper services in and out of Europe, this study flags potential overnight sleeper routes with large passenger volumes and adequate travel distances. The carbon saving potential of these routes has been analyzed in both the short run and long run. In the long run, this study introduces the scenario that synthetic aviation fuels will be adopted in air transport to reduce its environmental impacts. After a passenger split between overnight sleepers and air transport based on a case study, this study finds that overnight sleepers have negligible carbon reduction effect in the short run. In the long run, with the introduction of synthetic aviation fuels and carbon-free electricity in the transport sector, air transport can reach carbon-neutrality. However, to carry the same number of passengers to various locations, air transport with synthetic fuel will consume 5.9 to 7.7 times more energy than railway transport. Furthermore, air transport’s non-CO2 effects also have global warming potential. Compared with air transport under the synthetic fuels scheme, railway transport shows considerable competitive advantages in energy efficiency and general environmental impact in the long run. This study concludes that overnight sleepers have shown negligible decarbonization effects in the short run. In the long run, railway transport will have advantages in energy efficiency and environmental impacts over air transport when synthetic aviation fuel is considered. However, overnight sleeper has an upper limit of passenger base because it has a relatively limited travel range. Further studies are needed to plan future short-haul passenger transport modal shift by considering more options, such as high-speed railway.

description: In-phase synchronization is a stable state of identical Kuramoto oscillators coupled on a network with identical positive connections, regardless of network topology. However, this fact does not mean that the networks always synchronize in-phase because other attractors besides the stable state may exist. The critical connectivity $μ_{\mathrm{c}}$ is defined as the network connectivity above which only the in-phase state is stable for all the networks. In other words, below $μ_{\mathrm{c}}$, one can find at least one network which has a stable state besides the in-phase sync. The best known evaluation of the value so far is $0.6828\cdots\leqμ_{\mathrm{c}}\leq0.75$. In this paper, focusing on the twisted states of the circulant networks, we provide a method to systematically analyze the linear stability of all possible twisted states on all possible circulant networks. This method using integer programming enables us to find the densest circulant network having a stable twisted state besides the in-phase sync, which breaks a record of the lower bound of the $μ_{\mathrm{c}}$ from $0.6828\cdots$ to $0.6838\cdots$. We confirm the validity of the theory by numerical simulations of the networks not converging to the in-phase state.

Year: 2021

description: The production of fish in aquaculture can be affected by monogeneans, which are parasitic flatworms. The drugs available to control these parasites are few and not always effective. This work presents a methodological framework based on the monogenean Rhabdosynochus sp. in order to identify drug targets and to identify drugs with affinity to the identified proteins (drug repositioning). For this, the transcriptome of Rhabdosynochus sp. will be sequenced and assembled, and the proteins will be predicted and annotated. Subsequently, the proteases and protease inhibitors, ligand-associated ion channels, G-protein-coupled receptors and kinases proteins will be identified by aligning the Rhabdosynochus sp. proteins against the protein databases MEROPS, LGIC, KINBASE and Pfam, using the sequence alignment programs Blast, HMMER and OMA. The identified proteins will be aligned against the ChEMBL, DrugBank and Therapeutic Targets Database, which have information of the proteins that can be used as a target. A computational drug repositioning analysis will be performed to identify any drug with affinity to the target proteins of Rhabdosynochus sp. For this, information on the three-dimensional structure of chemical compounds will be obtained from the ZINC15 database, and the three-dimensional structure of proteins will be obtained through the structural modeling of amino acid sequences using the Modeller program. The analysis of the protein-drug interaction and the virtual screening will be performed in the AutoDock Vina and UCSF Chimera programs, respectively. Finally, we will evaluate the anthelmintic activity of the compound that present the best results in computational analyzes, by means of an in vitro phenotypic screening of the whole organism.

description: We report an implementation of the momentum space quantum Monte Carlo (QMC) method on the interaction model for the twisted bilayer graphene (TBG) at integer fillings. The long-range Coulomb repulsion is treated exactly with the flat bands, spin and valley degrees of freedom of electrons taking into account. We prove the absence of the minus sign problem for QMC simulation at integer fillings when either the two valley or the two spin degrees of freedom are considered. By taking the realistic parameters of the twist angle and interlayer tunnelings into the simulation, we benchmark the QMC data with the exact band gap obtained at the chiral limit, to reveal the insulating ground states at the charge neutrality point (CNP). Then, with the exact Green's functions from QMC, we perform stochastic analytic continuation to obtain the first set of single-particle spectral function for the TBG model at CNP. Our momentum space QMC scheme therefore offers the controlled computation pathway for systematic investigation of the electronic states in realistic TBG model at various electron fillings.

description: We consider the open spin-s XXZ quantum spin chain with N sites and general integrable boundary terms for generic values of the bulk anisotropy parameter, and for values of the boundary parameters which satisfy a certain constraint. We derive two sets of Bethe Ansatz equations, and find numerical evidence that together they give the complete set of $(2s+1)^{N}$ eigenvalues of the transfer matrix. For the case s=1, we explicitly determine the Hamiltonian, and find an expression for its eigenvalues in terms of Bethe roots.

description: Quantitative bone single-photon emission computed tomography (QBSPECT) has the potential to provide a better quantitative assessment of bone metastasis than planar bone scintigraphy due to its ability to better quantify activity in overlapping structures. An important element of assessing response of bone metastasis is accurate image segmentation. However, limited by the properties of QBSPECT images, the segmentation of anatomical regions-of-interests (ROIs) still relies heavily on the manual delineation by experts. This work proposes a fast and robust automated segmentation method for partitioning a QBSPECT image into lesion, bone, and background. We present a new unsupervised segmentation loss function and its semi- and supervised variants for training a convolutional neural network (ConvNet). The loss functions were developed based on the objective function of the classical Fuzzy C-means (FCM) algorithm. We conducted a comprehensive study to compare our proposed methods with ConvNets trained using supervised loss functions and conventional clustering methods. The Dice similarity coefficient (DSC) and several other metrics were used as figures of merit as applied to the task of delineating lesion and bone in both simulated and clinical SPECT/CT images. We experimentally demonstrated that the proposed methods yielded good segmentation results on a clinical dataset even though the training was done using realistic simulated images. A ConvNet-based image segmentation method that uses novel loss functions was developed and evaluated. The method can operate in unsupervised, semi-supervised, or fully-supervised modes depending on the availability of annotated training data. The results demonstrated that the proposed method provides fast and robust lesion and bone segmentation for QBSPECT/CT. The method can potentially be applied to other medical image segmentation applications.

description: The pure spinor heterotic string in a generic super Yang-Mills and supergravity background is considered. We determine the one-loop BRST anomaly at the cohomological level. We prove that it can be absorbed by consistent corrections of the classical constraints due to Berkovits and Howe, in agreement with the Green-Schwarz cancelation mechanism.

A Robust Model for Flux Density Calculations of Radio Halos in Galaxy Clusters: Halo-FDCA

description: Here we present Halo-FDCA, a robust open source Python package for modeling and estimating total flux densities of radio (mini) halos in galaxy clusters. Radio halos are extended ( ~200 - 1500 kpc in size) synchrotron emitting sources found in galaxy clusters that trace the presence of cosmic rays and magnetic fields in the intracluster medium (ICM). These sources are centrally located and have a low surface brightness. Their exact origin is still unknown but they are likely related to cosmic rays being re-accelerated in-situ by merger or sloshing driven ICM turbulence. The presented algorithm combines the numerical power of the Markov Chain Monte Carlo routine and multiple theoretical models to estimate the total radio flux density of a radio halo from a radio image and its associated uncertainty. This method introduces a flexible analytic fitting procedure to replace existing simplistic manual measurements prone to biases and inaccuracies. It allows to easily determine the properties of the emission and is particularly suitable for future studies of large samples of clusters.

Swift/XRT observes the fifth outburst of the periodic Supergiant Fast X-ray Transient IGR J11215-5952

description: IGR J11215-5952 is a hard X-ray transient source discovered in April 2005 with INTEGRAL and a confirmed member of the new class of High Mass X-ray Binaries, the Supergiant Fast X-ray Transients (SFXTs). Archival INTEGRAL data and RXTE observations showed that the outbursts occur with a periodicity of ~330 days. Thus, IGR J11215-5952 is the first SFXT displaying periodic outbursts, possibly related to the orbital period. We performed a Target of Opportunity observation with Swift with the main aim of monitoring the source behaviour around the time of the fifth outburst, expected on 2007 Feb 9. The source field was observed with Swift twice a day (2ks/day) starting from 4th February, 2007, until the fifth outburst, and then for ~5 ks a day afterwards, during a monitoring campaign that lasted 23 days for a total on-source exposure of ~73 ks. This is the most complete monitoring campaign of an outburst from a SFXT. The spectrum during the brightest flares is well described by an absorbed power law with a photon index of 1 and N_H~1 10^22 cm^-2. A 1-10 keV peak luminosity of ~10^36 erg s^-1 was derived (assuming 6.2 kpc, the distance of the optical counterpart). These Swift observations are a unique data-set for an outburst of a SFXT, thanks to the combination of sensitivity and time coverage, and they allowed a study of IGR J11215-5952 from outburst onset to almost quiescence. We find that the accretion phase lasts longer than previously thought on the basis of lower sensitivity instruments observing only the brightest flares. The observed phenomenology is consistent with a smoothly increasing flux triggered at the periastron passage in a wide eccentric orbit with many flares superimposed, possibly due to episodic or inhomogeneous accretion.

Europe and Slave Protests in the Americas (1780-1850)
Creators: name: Geary, Dick
Publisher: name: Moving the Social
Year: 2015

description: This contribution firstly analyses the extent to which the Revolutions in France and Haiti in the late 18th century transformed the nature of slave revolts, which, according to Eugene Genovese, now aimed at the destruction of slavery as a system and were based on a modern ideology of 'the Rights of Man' rather than an 'African call to holy war'. It disputes Genovese's claims on the grounds that slave revolts before 1789 were no mere attempt to restore Africa; that conversely many slave revolts after that date continued to be led by African-born slaves with non-European agendas; that the relationship between ideological models and the motives of rebellious slaves were at the very least unclear; and that this was even true of in the case of Haiti. Secondly comparisons are made between the various forms of individual and collective protest adopted by slaves and those pursued by European workers. Many similarities are established, particularly in the field of economic bargaining, yet the presence of cultural transfers from Africa in the case of slaves constituted a crucial difference.

Was macht eigentlich die historische Protestforschung? Rückblicke, Resümee, Perspektiven
Creators: name: Gailus, Manfred
Publisher: name: Moving the Social
Year: 2015

description: The article deals with three and a half decades of research on historical protest in Germany. It scrutinises the reasons of its relative marginalisation since the early 1990s and tries to give some proposals for its renewal. After a short discussion of different meanings and concepts of “protest” and some preliminaries how the protest issue should be conceptualised for historical research, an overview is given on the early phases of “social protest” research and its contemporary shortcomings. Manfred Gailus argues for a more intensive research on what is conceived as “bad protest” like anti-Jewish violence etc. He also deals with the transformation of protest research (culturalisation, gender, history of violence) since the early 1990s in context of a general turn from social to cultural history. The author explains in detail that transnational comparisons as well as the globalisation of the issue, intensified receptions of recent debates and concepts of sociological movement research and issues like “civil society” may offer new opportunities. Finally, a short outlook on the future of protest research in today’s world full of protests is given.

description: According to extensive experimental findings, the Ginzburg temperature $t_{G}$ for ionic fluids differs substantially from that of nonionic fluids [Schröer W., Weigärtner H. 2004 {\it Pure Appl. Chem.} {\bf 76} 19]. A theoretical investigation of this outcome is proposed here by a mean field analysis of the interplay of short and long range interactions on the value of $t_{G}$. We consider a quite general continuous charge-asymmetric model made of charged hard spheres with additional short-range interactions (without electrostatic interactions the model belongs to the same universality class as the 3D Ising model). The effective Landau-Ginzburg Hamiltonian of the full system near its gas-liquid critical point is derived from which the Ginzburg temperature is calculated as a function of the ionicity. The results obtained in this way for $t_{G}$ are in good qualitative and sufficient quantitative agreement with available experimental data.
