description: The collision of two white dwarfs is a quite frequent event in dense stellar systems, like globular clusters and galactic nuclei. In this paper we present the results of a set of simulations of the close encounters and collisions of two white dwarfs. We use an up- to-date smoothed particle hydrodynamics code that incorporates very detailed input physics and an improved treatment of the artificial viscosity. Our simulations have been done using a large number of particles (~ 4 \times 10^5) and covering a wide range of velocities and initial distances of the colliding white dwarfs. We discuss in detail when the initial eccentric binary white dwarf survives the closest approach, when a lateral collision in which several mass transfer episodes occur is the outcome of the newly formed binary system, and which range of input parameters leads to a direct collision, in which only one mass transfer episode occurs. We also discuss the characteristics of the final configuration and we assess the possible observational signatures of the merger, such as the associated gravitational waveforms and the fallback luminosities. We find that the overall evolution of the system and the main characteristics of the final object agree with those found in previous studies. We also find that the fallback luminosities are close to 10^48 erg/s. Finally, we find as well that in the case of lateral and direct collisions the gravitational waveforms are characterized by large-amplitude peaks which are followed by a ring-down phase, while in the case in which the binary white dwarf survives the closest approach, the gravitational pattern shows a distinctive behavior, typical of eccentric systems.

description: In the last three decades, increased acknowledgement of the potential harms of gentrification have led to more study of its potential impacts on health and wellbeing for existing residents. This thesis aims to summarize and evaluate the potential health effects of gentrification as suggested by the literature consensus and compare these findings to perceptions within the public health establishment, as represented by joint Community Health Needs Assessments from forty-seven geographically diverse metropolitan areas. Content analysis of selected CHNAs revealed low rates of inclusion of gentrification-related language, even among cities experiencing intense gentrification. This lack of gentrification language stood in contrast to the broad inclusion of housing as an important social determinant of health among CHNAs.

description: We address the properties of optical solitons in thermal nonlinear media with a local refractive index defect that is capable to trap solitons launched even close to the sample boundary despite the boundary-mediated forces that tend to deflect all beams toward the center of the sample. We show that while such forces become more pronounced with increasing the input beam power the defect can trap only light below a critical power above which solitons are ejected. The dynamics of soliton ejection and the subsequent propagation may be controlled.

description: È stata analizzata situazione attuale della gestione degli utensili nell’azienda TE Connectivity e definita una soluzione TO-BE per risolvere varie problematiche. Sono state effettuate diverse mappature, la più importante riguarda l’inventario degli utensili utilizzati negli ultimi due anni. Le analisi effettuate per lo stato AS-IS riguardano la tracciabilità degli utensili, i produttori e fornitori chiave e le categorie di utensili più acquistate. Sono state analizzate le problematiche ricorrenti; per la risoluzione di esse è emerso che era necessario effettuare prima delle ulteriori analisi più specifiche. Le analisi effettuate riguardano la determinazione del punto di riordino e la suddivisione degli utensili in due categorie, in base alle quantità ordinate. Successivamente è stata definito uno stato TO-BE volto a risolvere i problemi riscontrati.
Would one rather store squeezing or entanglement in continuous variable quantum memories?

description: Given two quantum memories for continuous variables (e.g., the collective pseudo-spin of two atomic ensembles) and the possibility to perform passive optical operations (typically beam-splitters) on the optical modes before or after the storage, two possible scenarios arise resulting in generally different degrees of final entanglement. Namely, one could either store an entangled state and retrieve it directly from the memory, or rather store two separate single-mode squeezed states and then combine them with a beam-splitter to generate the final entangled state. In this paper, we address the question of which of these two options yields the higher entanglement. By adopting a well established descrip- tion of QND feedback memories, and a simple but realistic noise model, we analytically determine the optimal choice for several regions of noise parameters and quantify the advantage it entails, not only in terms of final entanglement but also in terms of the capability of the final state to act as a shared resource for quantum teleportation. We will see that, for 'ideal' or 'nearly ideal' memories, the more efficient of the two options is the one that better protects the quadrature subject to the largest noise in the memory (by increasing it and making it more robust).

Role of plasticity-related gene 1 palmitoylation in synapse plasticity
Creators: name: Nasseri, Glory
Publisher: name: University of British Columbia
Year: 2022

description: The formation and remodeling of specialized junctions between neurons, called synapses, requires precise distribution and trafficking of proteins to specialized compartments. Synapse plasticity refers to the continual changes in the strength and structure of these synaptic contacts that occur in response to neuronal activity. This is in large part mediated by post-translational modifications of synaptic proteins, including reversible protein palmitoylation, resulting in the strengthening and weakening of synaptic connections that underlies the cellular basis of learning and memory. To understand how the dynamic palmitoylation of neuronal proteins contributes to synaptic plasticity, we used an unbiased, proteomic approach to identify proteins that were differentially palmitoylated following a hippocampal-dependent fear conditioning learning paradigm in mice. In this study, we identified 121 hippocampal proteins, including several key synaptic proteins, whose palmitoylation status was altered 1 hour after contextual fear conditioning. A subset of the 121 differentially palmitoylated proteins was validated in vitro and the effects of dynamic palmitoylation on the function of a validated protein, lipid phosphate phosphatase-related protein 4 (LPPR4 – also referred to as plasticity-related gene 1, PRG-1), was investigated further. We demonstrate that PRG-1 palmitoylation is regulated by changes in neuronal activity associated with hippocampal learning as well as with chemical long-term potentiation (cLTP). We identified cysteine residues in PRG-1 that are palmitoylated and found that palmitoylation at these sites is important for dendritic spine formation. Furthermore, we demonstrate that increased palmitoylation of PRG-1 negatively regulates bioactive lipid uptake in dendritic spines and shafts and is important for activity-induced insertion of AMPA receptors into the postsynaptic membrane which is essential for synaptic strengthening. As palmitoylation iv can facilitate interactions between proteins and cellular membranes, we tested the hypothesis that neuronal activity modulates membrane surface levels of PRG-1 through palmitoylation. However, we discovered that activity-induced palmitoylation of PRG-1 had no effect on its surface expression and therefore likely functions through an alternative mechanism. These findings suggest that dynamic palmitoylation of PRG-1 contributes to hippocampal synapse plasticity by modulating bioactive lipid uptake, spine formation, and activity-induced AMPA receptor recruitment. Together, this study identifies dynamic palmitoylation networks which may be central to learning and memory.

description: We study a particle on a ring in presence of a dissipative Caldeira-Leggett environment and derive its response to a DC field. We find, through a 2-loop renormalization group analysis, that a large dissipation parameter $η$ flows to a fixed point $η_R=η_c=\hbar/2π$. We also reexamine the mapping of this problem to that of the Coulomb box and show that the relaxation resistance, of recent interest, is quantized for large $η$. For finite $η>η_c$ we find that a certain average of the relaxation resistance is quantized. We propose a box experiment to measure a quantized noise.

Ecological impacts of climate change and ecological adaptation

description: The study aimed to assess the responses of the flora of the Sundarbans mangrove of Bangladesh to increased salination. Empirical data was used to identify the adverse effect of salinity. Based on the respondents’ perceptions, it was found that significant off-site occurs in the previous freshwater rivers and canals. The pioneer Sundari trees (Heritiera fomes) are affected by Dieback disease due to increased salinity. Dieback contributes to the loss of canopy coverage and produces weak crowns, with sparse foliage and a good proportion of dead twigs and branches. It was revealed that the declining trend of the abundance of Nypa palm (Nypa fruticans) and Mangrove Date Palm (Phoenix paludosa) was observed in their historical habitat areas. The respondents opined that Keora (Sonneratia apetala) and Bain (Avicennia Officinalis) replace Sundari (Heritiera fomes), Bain (Avicennia Officinalis), Kakra (Bruguiera gymnorhiza), Passur (Xylocarpus mekongensis) and Dhondul tree (Xylocarpus granatum) species. Consequently, the species composition, species richness, natural regeneration, and vertical and horizontal structure of the mangrove are changing due to increased salinity.
Remark on the subtractive renormalization of quadratically divergent scalar mass

description: The quadratically divergent scalar mass is subtractively renormalized unlike other divergences which are multiplicatively renormalized. We re-examine some technical aspects of the subtractive renormalization, in particular, the mass independent renormalization of massive $λϕ^{4}$ theory with higher derivative regularization. We then discuss an unconventional scheme to introduce the notion of renormalization point $μ$ to the subtractive renormalization in a theory defined by a large fixed cut-off $M$. The resulting renormalization group equation generally becomes inhomogeneous but it is transformed to be homogeneous. The renormalized scalar mass consists of two components in this scheme, one with the ordinary anomalous dimension and the other which is proportional to the renormalization scale $μ$. This scheme interpolates between the theory defined by dimensional regularization and the theory with un-subtracted quadratic divergences.

description: Racism is endemic, yet racism is often thought to be a topic for debate. It is not. In this paper, I have assembled a range of several interesting or provocative ideas related to understanding the historical legacy of racism and inequality, as well as some potential solutions or actions to mitigate the effects of racism in today’s society. These ideas are not exhaustive, but they provide a starting point for teachers making an effort to turn the moments we’ve seen in Ferguson, Baltimore, and Minneapolis into a movement.

description: This paper traces the experiences of 12 elementary school teachers working at a high-poverty school in the urban Southwest, rated an “F” by the state department of education. In the tradition of phenomenological qualitative research, we utilized interviews, focus groups and participant observation over the course of one academic year to examine how teachers come to understand, negotiate and resist policy mandates that position them and their students as failing. Findings indicate that teachers experienced three dimensions of trauma as a result of increasingly oppressive policy mandates including the physical toll of an unreasonable workload, psychic disequilibrium and ongoing marginalization.

description: We present a method to determine the shot noise in quantum systems from knowledge of their time evolution - the latter being obtained using numerical simulation techniques. While our ultimate goal is the study of interacting systems, the main issues for the numerical determination of the noise do not depend on the interactions. To discuss them, we concentrate on the single resonant level model, which consists in a single impurity attached to non-interacting leads, with spinless fermions. We use exact diagonalisations (ED) to obtain time evolution, and are able to use known analytic results as benchmarks. We obtain a complete characterization of finite size effects at zero frequency, where we find that the finite size corrections scale $\propto G^2$, $G$ the differential conductance. We also discuss finite frequency noise, as well as the effects of damping in the leads.

The New Teachers’ Roundtable: A Case Study of Collective Resistance
Creators: name: Sondel, Beth Leah
Publisher: name: Critical Education
Year: 2017

description: The New Teachers’ Roundtable (NTRT) is a democratically run collective of new teachers who have become critical of neoliberal reform since relocating to New Orleans, with organizations including Teach For America, as a part of the post-Katrina overhaul of public schools. Through interviews and observations, this study examines the ways in which collective members support each other in attempts to navigate experiences they perceive as dehumanizing to themselves, their students, and their students’ communities. By developing relationships amongst themselves and with other stakeholders affected by and resisting privatization, they are able to challenge their own privilege and begin shifting their perspective and pedagogy. This study aims to contribute to our understanding of how teachers who have been affiliated with market-based movements can be galvanized to work in service of movements that are democratic, anti-racist, and accountable to communities.

description: We study the measurement-induced enhancement of the spontaneous decay (called quantum anti-Zeno effect) for a two-level subsystem, where measurements are treated as couplings between the excited state and an auxiliary state rather than the von Neumann's wave function reduction. The photon radiated in a fast decay of the atom, from the auxiliary state to the excited state, triggers a quasi-measurement, as opposed to a projection measurement. Our use of the term "quasi-measurement" refers to a "coupling-based measurement". Such frequent quasi-measurements result in an exponential decay of the survival probability of atomic initial state with a photon emission following each quasi-measurement. Our calculations show that the effective decay rate is of the same form as the one based on projection measurements. What is more important, the survival probability of the atomic initial state which is obtained by tracing over all the photon states is equivalent to the survival probability of the atomic initial state with a photon emission following each quasi-measurement to the order under consideration. That is because the contributions from those states with photon number less than the number of quasi-measurements originate from higher-order processes.

description: This fluid dynamics video reports how to form liquid core capsules having a thin hydrogel elastic membrane named liquid pearls. These fish-egg like structures are initially made of a millimetric liquid drop, aqueous or not, coated with an aqueous liquid film containing sodium alginate that gels once the double drop enters a calcium chloride bath. The creation of such pearls with micrometer thick membrane requires to suppress mixing until gelling takes place. Here, we show that superimposing a two dimensional surfactant precipitation at the interface confers a transient rigidity that can damp the shear induced instability at impact. Based on this, pearls containing almost any type of liquids can be created. The video focuses on the dynamics of the entry of the compound drop into the gelling bath.

description: Rice monoculture in Bangladesh affects the associated biodiversity. The study aimed to identify the alternatives to rice monoculture. Both primary and secondary data were used in this study. It was found that tubers notably potato, sweet potato, aroids, taro, yam and cassava cultivation can mitigate the negative impacts of the monoculture and ensure food security. In addition, crop diversification can improve soil health and control insects and pathogens. The study outlined a pathway of cleaner production for environmental sustainability and responsible consumption to minimize wastage.
Sliding coherence window technique for hierarchical detection of continuous gravitational waves

description: A novel hierarchical search technique is presented for all-sky surveys for continuous gravitational-wave sources, such as rapidly spinning nonaxisymmetric neutron stars. Analyzing yearlong detector data sets over realistic ranges of parameter space using fully coherent matched-filtering is computationally prohibitive. Thus more efficient, so-called hierarchical techniques are essential. Traditionally, the standard hierarchical approach consists of dividing the data into nonoverlapping segments of which each is coherently analyzed and subsequently the matched-filter outputs from all segments are combined incoherently. The present work proposes to break the data into subsegments shorter than the desired maximum coherence time span (size of the coherence window). Then matched-filter outputs from the different subsegments are efficiently combined by sliding the coherence window in time: Subsegments whose timestamps are closer than coherence window size are combined coherently, otherwise incoherently. Compared to the standard scheme at the same coherence time baseline, data sets longer by about 50-100% would have to be analyzed to achieve the same search sensitivity as with the sliding coherence window approach. Numerical simulations attest to the analytically estimated improvement.

Thermoelectric and electrical transport properties of Bi2Te3 compacted nanoparticles bulk material

Publisher: name: Universität Bielefeld
Year: 2021
Subjects: subject: 530

description: Three-dimensional (3D) topological insulators (TI) host surface carriers with extremely high mobility. However, their transport properties are typically dominated by bulk carriers that outnumber the surface carriers by orders of magnitude. We herein present a strategy to overcome the problem of bulk carrier domination by using 3D TI nanoparticles, which were compacted by hot-pressing to macroscopic nanograined bulk samples. Bi2Te3 nanoparticles well known for their excellent thermoelectric and 3D TI properties serve as our model system. As key enabler for this approach, we applied a specific synthesis that creates nanoparticles with a low level of impurities and surface contamination. The compacted nanograined bulk contains a high number of interfaces and grain boundaries. Here we show that these samples exhibit metallic-like electrical transport properties and a distinct weak antilocalization. A downwards trend in the electrical resistivity at temperatures below 5 K was attributed to an increase in the coherence length by applying the Hikami-Larkin-Nagaoka model. THz time-domain spectroscopy revealed a dominance of the surface transport at low frequencies with a mobility of above 〖10〗^3 cm^2 V^(-1) s^(-1) even at room temperature. These findings clearly demonstrate that nanograined bulk Bi2Te3 features surface carrier properties that are of importance for technical applications.

Lessons on Citizenship and Democratic Power Literacy from Undocumented Youth
Creators: name: Parkhouse, Hillary
Publisher: name: Critical Education
Year: 2017

description: To create a society in which power is more equally accessible, we must teach our youth not only about civics and government, but also how to use political tools in order to effect social change. In this essay, I argue for teaching power literacy in place of traditional citizenship education on the grounds that the former has greater potential for increasing students’ political efficacy and their abilities to apply knowledge of civics to the real-world issues that affect them. To illustrate the concept of power literacy, I draw on a case study of a grassroots, undocumented youth activist organization fighting for in-state tuition legislation in North Carolina. Members of this group, which was entirely youth-founded and youth-led, taught themselves lobbying, civil disobedience, and other political strategies that far surpass the knowledge and skills typically presented in school-based citizenship education. Their work exemplifies the type of power literacy that we should teach all youth if we wish them to have the skills necessary to address the social inequalities that currently undercut American democracy.

description: Based on the vector angular spectrum method and the stationary phase method and the fact that a circular aperture function can be expanded into a finite sum of complex Gaussian functions, the analytical vectorial structure of a four-petal Gaussian beam (FPGB) diffracted by a circular aperture is derived in the far field. The energy flux distributions and the diffraction effect introduced by the aperture are studied and illustrated graphically. Moreover, the influence of the f-parameter and the truncation parameter on the nonparaxiality is demonstrated in detail. In addition, the analytical formulas obtained in this paper can degenerate into un-apertured case when the truncation parameter tends to infinity. This work is beneficial to strengthen the understanding of vectorial properties of the FPGB diffracted by a circular aperture.

description: The present article examines an enduring educational inequality- nondominant students’ disproportionate representation in special education programs. From a Marxist historical materialist perspective, racial disproportionality forms a systemic tension that offers a significant opportunity to deeply examine and transform school systems. I first provide a social-historical-spatial examination of racial disproportionality and disability classification process. Then, I detail how formative intervention, an activity theory-based systemic intervention model, can be instrumental in capacity building in local schools to examine and intervene racial disproportionality. The formative intervention methodology that I present in this article aims to re-mediate complex ecologies of school systems by transforming exclusionary processes with local stakeholders who reproduce and are negatively affected by those unjust processes and outcomes.

description: Our concerns regarding the assumptions behind, politics of, and implications of using edTPA, an assessment tool purported to assess whether U.S. student teachers are “ready for the job” of teaching, are our primary focus here. We write from our perspectives as teacher educators in New York state, one of the states for which the edTPA is required for teacher licensure, drawing on diverse theoretical perspectives as we lay out our arguments against the problematic impacts of this so-called educational reform. We will strive to “connect the dots” as we see the multiple, and at times radical, changes to the field as all of a piece, making education just one more corporate project at the intersection of money, politics, and power. Last, we will offer some examples of as well as suggestions for resistance to this project, highlighting pedagogies of informed hope.

Fifteen of the 19 items associated with a customer orientation included in the survey (N=3885, n=1085, RR= 28%) exhibited statistically significant changes, all in ways consistent with a greater expression of a customer approach.  Results also indicated that while students increasingly expressed a customer orientation, overall, they continued not to express beliefs consistent with a customer approach. Implications are discussed within the framework of neoliberal ideology.

Making Marxist Pedagogy Magical: From Critique to Imagination, or, How Bookkeepers Set Us Free
Creators: name: Ford, Derek R.
Publisher: name: Critical Education
Year: 2017

description: Claiming that critical education generally, and marxist education specifically, is stuck in a dead-end of impotent critique, this article seeks to reinvigorate the fields by making marxist pedagogy magical. We have to, in other words, not just engage in productive and revolutionary critique, but more importantly, engage in the magical act of imagining possible futures. Selectively reading the three volumes of Marx's Capital, I demonstrate that Marx figures communism is different ways and with seemingly antagonistic emphases. At heart, then, Marx poses communism as a pedagogical problem and as one that demands magical thinking. Insisting that our history and present be the real concrete stuff of learning, experimenting, and doing, I next make the claim that we have already been post-capitalist (i.e., socialist), and that we have to reclaim the successful history of the international struggle of the dispossessed and exploited. In disavowing this history, we reinforce the neoliberal claim that there is no alternative to the market and democracy. I conclude by offering the U.S.-based Party for Socialism and Liberation as an example of magical marxist educators, calling on their imaginative Party program.

Our simulations introduce the following new element: we assume that after 200 kyr of evolution in a dense environment Mira entered the Local Bubble (low density coronal gas). As Mira enters the bubble, the head of the comet expands quite rapidly, while the tail remains well collimated for a 100 kyr timescale. The result is a broad-head/narrow-tail structure that resembles the observed morphology of Mira's comet. The simulations were carried out with our new adaptive grid code WALICXE, which is described in detail.

description: Il presente studio rappresenta un importante progresso nell’ambito delle funzioni esecutive e del loro ruolo nel successo scolastico dei bambini. Grazie all'utilizzo di un programma di allenamento cognitivo basato sul metodo di Benso e abbinato al movimento, questo studio pilota ha esaminato l'efficacia dell'intervento nel potenziare le abilità cognitive associate alle funzioni esecutive.

Subjects: Forestry management and environment

description: The overarching objective of the study was to assess the role of forestation in maintaining ecological integrity in Bangladesh. Both primary and secondary data were used in this study. It was found that environmental degradation can be improved through plantation and forestation. Afforestation can combat the adverse effect of climate change and improve the existing microclimatic pattern. The forestation can act as a greenbelt against tropical cyclones in the coastal areas. The depleted biodiversity can be enriched by controlling incremental biological Invasion. It can ease riparian habitat complexity and improve soil qualities. The study recommended integrated forest management emphasizing riparian plantation, fallow land plantation, gap filling, natural succession, natural regeneration and community-based coastal forestation.

description: Fibrosis causes nearly 45% of all deaths in industrialized nations. Currently, no efficient antifibrotic therapy exists. Detailed understanding of the mechanisms governing efficient tissue regeneration and of how they go awry in fibrotic pathologies will likely inform therapeutic approaches. The remarkable healing capacity of skeletal muscle and development of rodent models for muscular dystrophies, in which fibrosis is a common outcome, makes skeletal muscle an excellent candidate to study tissue regeneration and fibrosis. In contrast to infiltrating macrophages, the role of tissue resident macrophages (RMs) during regeneration or fibrosis is not well-understood, mainly due to the lack of a specific marker for their identification. In the first part of this study, using a combination of parabiosis, lineage tracing, and single-cell transcriptomics we identified a population of muscle resident LYVE1+TIM4+ macrophages that locally self-renew (self-renewing resident macrophages, SRRMs). Using a Colony Stimulating Factor 1 Receptor (CSF1R) inhibition/withdrawal approach to specifically deplete SRRMs, we showed that SRRMs provide a non-redundant function in clearing damage-induced apoptotic cells. We further found that depletion of RMs through CSF1R inhibition changed muscle fiber composition from damage-sensitive glycolytic fibers towards damage-resistant oxidative fibers, protecting dystrophic muscle against contraction induced injury. This finding has therapeutic potential in light of the ongoing clinical testing of CSF1R inhibitors. As a well-known pro-inflammatory cytokine with diverse roles in antimicrobial and antitumor immunity, a small amount of conflicting evidence exists regarding the source and function of IFNγ during the regeneration process following a sterile injury. In the second part of this study, we showed that a population of natural killer cells is the main source of IFNγ in regenerating muscle. We found that the absence of IFNγ per se has no effect on regeneration. However, the role of IFNγ gets unmasked when TNFα is neutralized. Using three different transgenic mice strains to conditionally deplete the IFNγ receptor 1 on the surface of satellite cells, fibro-adipogenic progenitors (FAPs), or macrophages, we found that IFNγ acts through macrophages and FAPs to support muscle regeneration. In contrast to the common belief, we found that IFNγ peaks when pro-inflammatory macrophages are switching to an anti-inflammatory phenotype.

description: We experimentally investigate the Bragg reflection of light at one-dimensionally ordered atomic structures by using cold atoms trapped in a laser standing wave. By a fine tuning of the periodicity, we reach the regime of multiple reflection due to the refractive index contrast between layers, yielding an unprecedented high reflectance efficiency of 80%. This result is explained by the occurrence of a photonic band gap in such systems, in accordance with previous predictions.

Random lasso

description: We propose a computationally intensive method, the random lasso method, for variable selection in linear models. The method consists of two major steps. In step 1, the lasso method is applied to many bootstrap samples, each using a set of randomly selected covariates. A measure of importance is yielded from this step for each covariate. In step 2, a similar procedure to the first step is implemented with the exception that for each bootstrap sample, a subset of covariates is randomly selected with unequal selection probabilities determined by the covariates' importance. Adaptive lasso may be used in the second step with weights determined by the importance measures. The final set of covariates and their coefficients are determined by averaging bootstrap results obtained from step 2. The proposed method alleviates some of the limitations of lasso, elastic-net and related methods noted especially in the context of microarray data analysis: it tends to remove highly correlated variables altogether or select them all, and maintains maximal flexibility in estimating their coefficients, particularly with different signs; the number of selected variables is no longer limited by the sample size; and the resulting prediction accuracy is competitive or superior compared to the alternatives. We illustrate the proposed method by extensive simulation studies. The proposed method is also applied to a Glioblastoma microarray data analysis.

description: We describe a method which allows one to study hidden symmetries in a large class of strongly coupled supersymmetric gauge theories in three dimensions. We apply this method to the ABJM theory and to the infrared limit of N=4 SQCD with adjoint and fundamental matter. We show that the U(N) ABJM model with Chern-Simons level k=1 or k=2 has hidden N=8 supersymmetry. Hidden supersymmetry is also shown to occur in N=4 d=3 SQCD with one fundamental and one adjoint hypermultiplet. The latter theory, as well as the U(N) ABJM theory at k=1, are shown to have a decoupled free sector. This provides evidence that both models are dual to the infrared limit of N=8 U(N) super-Yang-Mills theory.

description: The pioneering work of Deegan et al. [Nature 389, (1997)] showed how a drying sessile droplet suspension of particles presents a maximum evaporating flux at its contact line which drags liquid and particles creating the well known coffee stain ring. In this Fluid Dynamics Video, measurements using micro Particle Image Velocimetry and Particle Tracking clearly show an avalanche of particles being dragged in the last moments, for vanishing contact angles and droplet height. This explains the different characteristic packing of the particles in the layers of the ring: the outer one resembles a crystalline array, while the inner one looks more like a jammed granular fluid. Using the basic hydrodynamic model used by Deegan et al. [Phys. Rev. E 62, (2000)] it will be shown how the liquid radial velocity diverges as the droplet life comes to an end, yielding a good comparison with the experimental data.
