The Ambiguous Position of Cooperatives vis-a-vis the Issue of "Difference"

description: The common meaning of "difference" when refeITed to cooperatives is what is supposed to distinguish them from non-cooperative organizations and to enable them to assert their distinctiveness in their surrounding context. Examination of past and present experiences, however, shows that the cooperative difference has been challenged from both without and within the cooperative camp. The paper examines the ambiguous position of cooperatives vis-a- vis capitalism, the thesis of "no-difference", the defensive position and the recent efforts to sustain their particularity. As high levels of economic activity tend to increase the distance between the association and the enterprise aspects of the cooperative, it ensues that pursuance of difference is helped by a state of low economic involvement (e.g., "social cooperatives") and, conversely, is hampered by a state of high economic involvement and risk, as is the case with production - mainly agricultural - cooperatives under strong market competition. Here ambiguities persist as to whether the emphasis should be on strengthening the economic or the social component of the cooperative.

description: We report the discovery of a binary composed of two brown dwarfs, based on the analysis of the microlensing event OGLE-2016-BLG-1469. Thanks to detection of both finite-source and microlens-parallax effects, we are able to measure both the masses $M_1\sim 0.05\ M_\odot$, $M_2\sim 0.01\ M_\odot$, and distance $D_{\rm L} \sim 4.5$ kpc, as well as the projected separation $a_\perp \sim 0.33$ au. This is the third brown-dwarf binary detected using the microlensing method, demonstrating the usefulness of microlensing in detecting field brown-dwarf binaries with separations less than 1 au.

description: All X-ray light curves of nova V4743 Sgr (2002), taken during and after outburst, contain a 0.75 mHz periodic signal that can most plausibly be interpreted as being excited by the rotation of the white dwarf in an intermediate polar system. This interpretation faces the challenge of an apparent multi-frequency nature of this signal in the light curves taken days 180 and 196 after outburst. We show that the multi-sine fit method, based on a superposition of two sine functions, yields two inherently indistinguishable solutions, i.e. the presence of two close frequencies, or a single signal with constant frequency but variable modulation amplitude. Using a power spectrum time map, we show that on day 180, a reduction of the modulation amplitude of the signal coincides with a substantial overall flux decline while on day 196, the signal was only present during the first half of the observation. Supported by simulations, we show that such variations in amplitude can lead to false beating that manifests itself as a multiple signal if computing a periodogram over the full light curve. Therefore, the previously proposed double frequency nature of both light curves was probably an artefact while we consider a single signal with frequency equal to the white dwarf rotation as more plausible.

description: An extreme biomass burning event occurred in Indonesia from September through October 2015 due to severe drought conditions, partially caused by a major El Niño event, thereby allowing for significant burning of peatland that had been previously drained. This event had the highest sustained aerosol optical depths (AODs) ever monitored by the global Aerosol Robotic Network (AERONET). The newly developed AERONET Version 3 algorithms retain high AOD at the longer wavelengths when associated with high Ångström exponents (AEs), which thereby allowed for measurements of AOD at 675 nm as high as approximately 7, the upper limit of Sun photometry. Measured AEs at the highest monitored AOD levels were subsequently utilized to estimate instantaneous values of AOD at 550 nm in the range of 11 to 13, well beyond the upper measurement limit. Additionally, retrievals of complex refractive indices, size distributions, and single scattering albedos (SSAs) were obtained at much higher AOD levels than possible from almucantar scans due to the ability to perform retrievals at smaller solar zenith angles with new hybrid sky radiance scans. For retrievals made at the highest AOD levels the fine-mode volume median radii were ~0.25–0.30 micron, which are very large particles for biomass burning. Very high SSA values (~0.975 from 440 to 1,020 nm) are consistent with the domination by smoldering combustion of peat burning. Estimates of the percentage peat contribution to total biomass burning aerosol based on retrieved SSA and laboratory measured peat SSA were ~80–85%, in excellent agreement with independent estimates.

description: Exposure of lung cells in vitro or mice to single-walled carbon nanotubes (SWCNTs) directly to the respiratory tract leads to a reduced host anti-viral immune response to infection with influenza A virus H1N1 (IAV), resulting in significant increases in viral titers. This suggests that unintended exposure to nanotubes via inhalation may increase susceptibility to notorious respiratory viruses that carry a high social and economic burden globally. However, the molecular mechanisms that contribute to viral susceptibility have not been elucidated. In the present study, we identified the retinoic acid-induced gene I (RIG-I) like receptors (RLRs)/mitochondrial antiviral signaling (MAVS) pathway as a target of SWCNT-induced oxidative stress in small airway epithelial cells (SAEC) that contribute to significantly enhanced influenza viral titers. Exposure of SAEC to SWCNTs increases viral titers while repressing several aspects of the RLR pathway, including mRNA expression of key genes (e.g. IFITs, RIG-I, MDA5, IFNβ1, CCL5). SWCNTs also reduce mitochondrial membrane potential without altering oxygen consumption rates. Our findings also indicate that SWCNTs can impair formation of MAVS prion-like aggregates, which is known to impede downstream activation of the RLR pathway and hence the transcriptional production of interferon-regulated anti-viral genes and cytokines. Furthermore, application of the antioxidant NAC alleviates inhibition of gene expression levels by SWCNTs, as well as MAVS signalosome formation, and increased viral titers. These data provide evidence of targeted impairment of anti-viral signaling networks that are vital to immune defense mechanisms in lung cells, contributing to increased susceptibility to IAV infections by SWCNTs.

description: Agricultural production has been in decline in Israel, especially in the wake of financial and ideological crisis in the kibbutzim and moshavim in the mid- 1980s. As part of a general process of transformation of the position of agricultural production in the economy and in national ideology, women's roles and positions in cooperative settlements have also shifted. This essay offers a critical review of research that has documented the place of women in the rural sector in Israel. It explores the existing data on women in three sub-segments of the rural sector: women in the Jewish cooperative and non-cooperative settlements and women in non-Jewish rural settings. Based on a more general analysis of the sociology of knowledge production about women in Israel, the essay proposes that there are serious gaps in our knowledge on women in the Israeli rural sector. The analysis offered in this essay suggests that more genderfocused research must be carried out in rural Israel if the impact of the recent dramatic transformation in both the cooperative and non-cooperative settlement is to be understood.

description: Vera Rubin-LSST will play a key role in the newborn multi-messenger astronomy field allowing us to study and identify the likely faint and rapidly fading electromagnetic counterparts of the hundreds gravitational wave (GW) events expected by the 2nd generation GW detectors network at full sensitivity. It also will operate in synergy with other multi-wavelength facilities available for our teams GRAWITA (GRAvitational Wave INAF TeAm) and ENGRAVE (Electromagnetic counterparts of gravitational wave sources at the Very Large Telescope) expressly dedicated to this project. Here we present all the activities we are carrying out to optimize the response of the Italian and European network of facilities to expected GW triggers, and how the team is working in the context of the search for electromagnetic counterparts of GW sources and their spectroscopic characterization, also in anticipation of the arrival of the Einstein Telescope, in which our large community is involved. All the activities are expected to provide means and opportunities to the Italian and European astronomical communities to have a leading role in the GW and Time Domain Astronomy.

description: The distribution of scientific citations for publications selected with different rules (author, topic, institution, country, journal, etc.) collapse on a single curve if one plots the citations relative to their mean value. We find that the distribution of shares for the Facebook posts re-scale in the same manner to the very same curve with scientific citations. This finding suggests that citations are subjected to the same growth mechanism with Facebook popularity measures, being influenced by a statistically similar social environment and selection mechanism. In a simple master-equation approach the exponential growth of the number of publications and a preferential selection mechanism leads to a Tsallis-Pareto distribution offering an excellent description for the observed statistics. Based on our model and on the data derived from PubMed we predict that according to the present trend the average citations per scientific publications exponentially relaxes to about 4.

Globalization and the "Cooperative Difference"

description: Opposing logics support the global capital market and cooperatives. The first, in its pursuit of maximum gain, tends to detach itself from non-economic considerations. The latter, in their pursuit of maximum member and community servicing, have to subordinate the economic to social and other meta-economic considerations if they want to preserve their difference and raison d' etre. For the purpose of this paper and drawing on Polanyi, the separateness of the economic from other institutions of society will be denoted as disembeddedness and its contrary as embeddedness. The disembeddedness/embeddedness phenomenon can be observed at the micro and macro level and is viewed here as strongly related to the "cooperative difference". It is argued that: I) the greater the degree of disembeddedness in a cooperative, the less it is likely to differ from non-cooperative organizations, mainly investor owned firms (IOFs); 2) the greater the degree of embeddedness in a cooperative, the more it is likely to differ from other organizations; 3) the greater the degree of global disembeddedness, the greater the capacity of mainstream economics to weaken the cooperatives; 4) the greater the degree of global embeddedness, the greater the cooperatives' capacity for asserting and defending their difference. These propositions are put to the test of empirical experiences.

description: The discretisation of an attribute refers to partitioning its continuous numerical values into intervals, each of which is associated a categorical label. The amount of such different categorical labels is called as target discretisation level of the continuous attribute. For data mining algorithms that can only work on discrete data, the discretisation will be necessary. At the same time, the discretisation can also make the original data more concise and interpretable. However, it is challenging to balance the target discretisation level and the information loss during the discretisation process. In this paper, we propose to use entropy of a continuous attribute as a benchmark to determine its target discretisation level for the first time. An entropy based naive unsupervised discretisation approach is also proposed and shows big advantages in terms of both data reduction and accuracy, which is evaluated by performing classifiers on the dataset whose continuous attributes are discretised based on the proposed approach. Our experiments on 28 datasets and 9 popular classifiers show that the accuracy of a discretisation approach will be largely affected when the target discretisation level of each continuous attribute is lower than the entropy benchmark. Meanwhile increasing the target discretisation level from the benchmark does not always improve the accuracy of the discretizer. These discoveries can provide valuable guidance to explore or optimise the approaches to the discretisation of continuous attributes.

description: Context. During the post-perihelion phase of the European Space Agency's Rosetta mission to comet 67P, the Optical, Spectroscopic, and Infrared Remote Imaging System on board the spacecraft took numerous image sequences of the near-nucleus coma, with many showing the motion of individual pieces of debris ejected from active surface areas into space. Aims. We aim to track the motion of individual particles in these image sequences and derive their projected velocities and accelerations. This should help us to constrain their point of origin on the surface, understand the forces that influence their dynamics in the inner coma, and predict whether they will fall back to the surface or escape to interplanetary space. Methods. We have developed an algorithm that tracks the motion of particles appearing as point sources in image sequences. Our algorithm employs a point source detection software to locate the particles and then exploits the image sequences' pair-nature to reconstruct the particle tracks and derive the projected velocities and accelerations. We also constrained the particle size from their brightness. Results. Our algorithm identified 2268 tracks in a sample image sequence. Manual inspection not only found that 1187 (~52%) of them are likely genuine, but in combination with runs on simulated data it also revealed a simple criterion related to the completeness of a track to single out a large subset of the genuine tracks without the need for manual intervention. A tentative analysis of a small (n = 89) group of particles exemplifies how our data can be used, and provides first results on the particles' velocity, acceleration, and radius distributions, which agree with previous work.

description: Being an unsupervised machine learning and data mining technique, biclustering and its multimodal extensions are becoming popular tools for analysing object-attribute data in different domains. Apart from conventional clustering techniques, biclustering is searching for homogeneous groups of objects while keeping their common description, e.g., in binary setting, their shared attributes. In bioinformatics, biclustering is used to find genes, which are active in a subset of situations, thus being candidates for biomarkers. However, the authors of those biclustering techniques that are popular in gene expression analysis, may overlook the existing methods. For instance, BiMax algorithm is aimed at finding biclusters, which are well-known for decades as formal concepts. Moreover, even if bioinformatics classify the biclustering methods according to reasonable domain-driven criteria, their classification taxonomies may be different from survey to survey and not full as well. So, in this paper we propose to use concept lattices as a tool for taxonomy building (in the biclustering domain) and attribute exploration as means for cross-domain taxonomy completion.

description: Scalar-tensor gravitational theories are important extensions of standard general relativity, which can explain both the initial inflationary evolution, as well as the late accelerating expansion of the Universe. In the present paper we investigate the cosmological solution of a scalar-tensor gravitational theory, in which the scalar field $ϕ$ couples to the geometry via an arbitrary function $F(ϕ$). The kinetic energy of the scalar field as well as its self-interaction potential $V(ϕ)$ are also included in the gravitational action. By using a standard mathematical procedure, the Lie group approach, and Noether symmetry techniques, we obtain several exact solutions of the gravitational field equations describing the time evolutions of a flat Friedman-Robertson-Walker Universe in the framework of the scalar-tensor gravity. The obtained solutions can describe both accelerating and decelerating phases during the cosmological expansion of the Universe.

description: We address the problem of a front propagation in chains with a bi-stable nondegenerate on-site potential and a nonlinear gradient coupling. For a generic nonlinear coupling, one encounters a special regime of transitions, characterized by extremely narrow fronts, far supersonic velocities of propagation and long waves in the oscillatory tail. This regime can be qualitatively associated with a shock wave. The front propagation can be described with the help of a simple reduced-order model; the latter delivers a kinetic law, which is almost not sensitive to fine details of the on-site potential. Besides, it is possible to predict all main characteristics of the transition front, including its shape and frequency and amplitude of the oscillatory tail. The numerical results are in a good agreement with the analytical predictions. The suggested approach allows one to consider the effects of an external pre-load and on-site damping. When the damping is moderate, the analysis remains in the frame of the reduced-order model. It is possible to consider the solution for the front propagating in the damped chain as a perturbation of the undamped dynamics. This approach yield reasonable predictions. When the damping is high, the transition front enters a completely different asymptotic regime. The gradient nonlinearity generically turns negligible, and the propagating front converges to the exact solution obtained from a simple linear continuous model.

description: We present a Zee model with a family dependent $Z_2$ symmetry for radiative neutrino masses. Our motivation is to get a model that correctly describes neutrino oscillation phenomena, while at the same time offers definite predictions. The imposed $Z_2$ symmetry greatly reduces the number of free parameters in the model. These parameters are then determined from the neutrino data, from which one can study its outcomes. Our setup only admits quasidegenerate neutrino masses with the sum of neutrino masses between 100 and 130 meV, the effective Majorana mass between 20 and 40 meV, and the effective electron neutrino mass between 48 and 53 meV. The ratio of the vacuum expectation values of the Higgs doublets, $\tbeta$, is found to be $\tbeta\lesssim 0.5$ and $\tbeta\gtrsim 10$. The former is ruled out by lepton flavor violation (LFV) processes, such as $μ\to eγ$ and $μ\to e$ conversion, which are determined up to two loops. For the latter, these LFV processes are within reach of the next generation of experiments. Moreover, for $\tbeta\gtrsim10$, the couplings of heavy neutral scalars to dimuon are significant. If they are sufficiently light, i.e., $\lesssim200$ GeV, collider search for their decays into muon pair provides a stronger constraint on most parts of the model parameter space than the LFV ones.

description: Long after its discovery superconductivity in alkali fullerides A$_3$C$_{60}$ still challenges conventional wisdom. The freshest inroad in such ever-surprising physics is the behaviour under intense infrared (IR) excitation. Signatures attributable to a transient superconducting state extending up to temperatures ten times higher than the equilibrium $T_c\sim$ 20 K have been discovered in K$_3$C$_{60}$ after ultra-short pulsed IR irradiation -- an effect which still appears as remarkable as mysterious. Motivated by the observation that the phenomenon is observed in a broad pumping frequency range that coincides with the mid-infrared electronic absorption peak still of unclear origin, rather than to TO phonons as has been proposed, we advance here a radically new mechanism. First, we argue that this broad absorption peak represents a "super-exciton" involving the promotion of one electron from the $t_{1u}$ half-filled state to a higher-energy empty $t_{1g}$ state, dramatically lowered in energy by the large dipole-dipole interaction acting in conjunction with Jahn Teller effect within the enormously degenerate manifold of $\big(t_{1u}\big)^2\big(t_{1g}\big)^1$ states. Both long-lived and entropy-rich because they are triplets, the IR-induced excitons act as a sort of cooling mechanism that permits transient superconductive signals to persist up to much larger temperatures.

Steroid hormone signaling synchronizes cell migration machinery, adhesion, and polarity to direct collective movement

description: Migratory cells – either individually or in cohesive groups – are critical for spatiotemporally-regulated processes such as embryonic development and wound healing. Their dysregulation is the underlying cause of formidable health problems such as birth defects and metastatic cancers. Border cell behavior during Drosophila oogenesis provides an effective model to study temporally-regulated, collective cell migration in vivo. Developmental timing in flies is primarily controlled by the steroid hormone ecdysone, which acts through a well-conserved, nuclear hormone receptor complex. Ecdysone signaling determines the timing of border cell migration but the molecular mechanisms governing this remain obscure. We found that border cell clusters expressing a dominant negative form of ecdysone receptor extend ineffective protrusions. Additionally, these clusters have aberrant spatial distributions of E-cadherin, apical domain markers and activated myosin that do not overlap. Remediating their expression or activity individually in ecdysone signaling-mutant clusters did not restore proper migration. We propose that ecdysone signaling synchronizes the functional distribution of E-cadherin, atypical protein kinase C, Discs large, and activated myosin post-transcriptionally to coordinate adhesion, polarity, and contractility and temporally control collective cell migration.

On a non-solenoidal approximation to the incompressible Navier-Stokes equations

Subjects: subject: Analysis of PDEs (math.AP)

description: We establish an asymptotic profile that sharply describes the behavior as $t\to\infty$ for solutions to a non-solenoidal approximation of the incompressible Navier-Stokes equations introduced by Temam. The solutions of Temam's model are known to converge to the corresponding solutions of the classical Navier-Stokes, e.g., in $L^3\_{\rm loc} (R^+ \times R^3)$, provided $ε\to0$, where $ε>0$ is the physical parameter related to the artificial compressibility term. However, we show that such model is no longer a good approximation of Navier-Stokes for large times: indeed, its solutions can decay much slower as $t\to+\infty$ than the corresponding solutions of Navier-Stokes.

description: We review our recent results on dark matter from Starobinsky supergravity. In this context, a natural candidate for Cold Dark Matter is the gravitino. On the other hand, assuming the supersymmetry broken at scales much higher than the electroweak scale, gravitinos are super heavy particles. In this case, they may be non-thermally produced during inflation, in turn originated by the scalaron field with Starobinsky's potential.Assuming gravitinos as Lightest supersymmetric particles (LSSP), the non-thermal production naturally accounts for the right amount of cold dark matter. Metastability of the gravitino LSSP leads to observable effects of their decay, putting constraints on the corresponding Unstable or Decaying Dark Matters scenarios. In this model, the gravitino mass is controlled by the inflaton field and it runs with it. This implies that a continuous spectrum of superheavy gravitinos is produced during the slow-roll epoch. Implications in phenomenology, model building in GUT scenarios, intersecting D-branes models and instantons in string theories are discussed.

description: Inspired by a handful of resemblances between words indicating smallness in the languages of the Tanzanian Rift, this talk is an initial survey therein of the semantic field of “smallness”. Focusing on lexical items and morphemes expressing the concepts /SHORT/, /FEW/, /SMALL/, /CHILD/, /LITTLE PEOPLE/, as well as diminutivising operations, this talk: 1) identifies forms expressing these concepts in the Rift languages, 2) identifies resemblances, and 3) discusses whether resemblances could be due to contact, genetic inheritance, or chance. Where contact is deemed possible, individual scenarios are proposed. Finally, reflection is made on the significance of qualities such as “smallness” having shared terms across languages, and suggestions are made for future research.
description: Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change.

A Novel Receiver Design with Joint Coherent and Non-Coherent Processing

description: In this paper, we propose a novel splitting receiver, which involves joint processing of coherently and non-coherently received signals. Using a passive RF power splitter, the received signal at each receiver antenna is split into two streams which are then processed by a conventional coherent detection (CD) circuit and a power-detection (PD) circuit, respectively. The streams of the signals from all the receiver antennas are then jointly used for information detection. We show that the splitting receiver creates a three-dimensional received signal space, due to the joint coherent and non-coherent processing. We analyze the achievable rate of a splitting receiver, which shows that the splitting receiver provides a rate gain of $3/2$ compared to either the conventional (CD-based) coherent receiver or the PD-based non-coherent receiver in the high SNR regime. We also analyze the symbol error rate (SER) for practical modulation schemes, which shows that the splitting receiver achieves asymptotic SER reduction by a factor of at least $\sqrt{M}-1$ for $M$-QAM compared to either the conventional (CD-based) coherent receiver or the PD-based non-coherent receiver.
Persistent vs. arrested spreading of biofilms at solid-gas interfaces - the role of surface forces

description: We introduce and analyze a model for osmotically spreading biofilm colonies at solid-air interfaces that includes wetting phenomena, i.e. surface forces. The model combines a hydrodynamic description for biologically passive liquid suspensions with bioactive processes. We show that wetting effects are responsible for a transition between persistent and arrested spreading and provide experimental evidence for the existence of this transition for Bacillus subtilis biofilms growing on agar substrates. In the case of arrested spreading, the biofilm is non-invasive albeit being biologically active. However, a small reduction in the surface tension of the biofilm is sufficient to induce spreading.
Theoretical Prediction of the Robust Intrinsic Half-Metallicity in Ni2N MXene with Different Types of Surface Terminations

description: Bare and surface-passivated Fe2N, Co2N, and Ni2N MXene were investigated by using density functional theory. Fe2N(OH)2, Fe2NO2, Co2NO2, Ni2NF2, Ni2N(OH)2, and Ni2NO2 are intrinsic half-metals, while other structures have antiferromagnetic ground states. The half-metallicity of Ni2NT2 (T = F, OH, and O) does not depend on the type of surface terminations and should be more realizable in experiments. The energy differences between the ferromagnetic and antiferromagnetic configurations of Ni2NT2 are several hundreds of meV per primitive cell. The Curie temperature should be above room temperature from the point of view of mean field approximation.

description: We present different types of cooperatives in Greenland and Nunavik, Canada, in order to assess two different developments. A first approach to comparisons leads to an anomaly suggesting the necessity of empirical analysis in the two regions. Why is it that Greenland never really managed to create a cooperative movement? Except for consumer cooperatives, the remaining types of supply and worker cooperatives were a failure. There were isolated success stories for a limited period of time, butthe general picture remains the same. Most of these cooperatives are liquidated, and we never saw multi-purpose cooperatives established. Quite the contrary took place in Nunavik, in the northern part of Quebec in Canada. Here we saw a viable cooperative movement, and everywhere local communities established multi-purpose cooperatives. At the same time a strong cooperative association evolved. It seems that cooperative supporting structures are essential to a cooperative success in an Arctic region
Intertube effects on one-dimensional correlated state of metallic single-wall carbon nanotubes probed by 13C NMR

description: The electronic states in isolated single-wall carbon nanotubes (SWCNTs) have been considered as an ideal realization of a Tomonaga-Luttinger liquid (TLL). However, it remains unclear whether one-dimensional correlated states are realized under local environmental effects such as the formation of a bundle structure. Intertube effects originating from other adjacent SWCNTs within a bundle may drastically alter the one-dimensional correlated state. In order to test the validity of the TLL model in bundled SWCNTs, low-energy spin excitation is investigated by nuclear magnetic resonance (NMR). The NMR relaxation rate in bundled mixtures of metallic and semiconducting SWCNTs shows a power-law temperature dependence with a theoretically predicted exponent. This demonstrates that a TLL state with the same strength as that for effective Coulomb interactions is realized in a bundled sample, as in isolated SWCNTs. In bundled metallic SWCNTs, we found a power-law temperature dependence of the relaxation rate, but the magnitude of the relaxation rate is one order of magnitude smaller than that predicted by theory. Furthermore, we found an almost doubled magnitude of the Luttinger parameter. These results indicate suppressed spin excitations with reduced Coulomb interactions in bundled metallic SWCNTs, which are attributable to intertube interactions originating from adjacent metallic SWCNTs within a bundle. Our findings give direct evidence that bundling reduces the effective Coulomb interactions via intertube interactions within bundled metallic SWCNTs.
