description: Multiply-connected Calabi-Yau threefolds are of particular interest for both string theorists and mathematicians. Recently it was pointed out that one of the generic degenerations of these spaces (occurring at codimension one in moduli space) is an isolated singularity which is a finite cyclic quotient of the conifold; these were called hyperconifolds. It was also shown that if the order of the quotient group is even, such singular varieties have projective crepant resolutions, which are therefore smooth Calabi-Yau manifolds. The resulting topological transitions were called hyperconifold transitions, and change the fundamental group as well as the Hodge numbers. Here Batyrev's construction of Calabi-Yau hypersurfaces in toric fourfolds is used to demonstrate that certain compact examples containing the remaining hyperconifolds - the Z_3 and Z_5 cases - also have Calabi-Yau resolutions. The mirrors of the resulting transitions are studied and it is found, surprisingly, that they are ordinary conifold transitions. These are the first examples of conifold transitions with mirrors which are more exotic extremal transitions. The new hyperconifold transitions are also used to construct a small number of new Calabi-Yau manifolds, with small Hodge numbers and fundamental group Z_3 or Z_5. Finally, it is demonstrated that a hyperconifold is a physically sensible background in Type IIB string theory. In analogy to the conifold case, non-perturbative dynamics smooth the physical moduli space, such that hyperconifold transitions correspond to non-singular processes in the full theory.

description: Theoretical proposals for spin ice analogs based on nanostructured superconductors have suggested larger flexibility for probing the effects of fluctuations and disorder than in the magnetic systems. In this work, we unveil the particularities of a vortex ice system by direct observation of the vortex distribution in a kagome lattice of paired antidots using scanning Hall probe microscopy. The theoretically suggested vortex ice distribution, lacking long range order, is observed at half matching field (H_{1}/2). Moreover, the vortex ice state formed by the pinned vortices is still preserved at 2H_{1}/3. This unexpected result is attributed to the introduction of interstitial vortices at these magnetic field values. Although the interstitial vortices increase the number of possible vortex configurations, it is clearly shown that the vortex ice state observed at 2H_{1}/3 is less prone to defects than at $H_{1}/2$. In addition, the non-monotonic variations of the vortex ice quality on the lattice spacing indicates that a highly ordered vortex ice state cannot be attained by simply reducing the lattice spacing. The optimal design to observe defect free vortex ice is discussed based on the experimental statistics. The direct observations of a tunable vortex ice state provides new opportunities to explore the order-disorder transition in artificial ice systems.

description: Motivated by the potential similarities between the underlying mechanisms of the enhanced memory storage capacity in black holes and in brain networks, we construct an artificial quantum neural network based on gravity-like synaptic connections and a symmetry structure that allows to describe the network in terms of geometry of a d-dimensional space. We show that the network possesses a critical state in which the gapless neurons emerge that appear to inhabit a (d-1)-dimensional surface, with their number given by the surface area. In the excitations of these neurons, the network can store and retrieve an exponentially large number of patterns within an arbitrarily narrow energy gap. The corresponding micro-state entropy of the brain network exhibits an area law. The neural network can be described in terms of a quantum field, via identifying the different neurons with the different momentum modes of the field, while identifying the synaptic connections among the neurons with the interactions among the corresponding momentum modes. Such a mapping allows to attribute a well-defined sense of geometry to an intrinsically non-local system, such as the neural network, and vice versa, it allows to represent the quantum field model as a neural network.

Hayes's (see record 2005-14939-011) comment on the target article "Induction and Categorization in Young Children: A Similarity-Based Model" (V. M. Sloutsky & A. V. Fisher, 2004a). The response discusses points of agreement and disagreement with Heit and Hayes; phenomena predicted by similarity, induction, naming, and categorization (SINC); and relationships between SINC and models of verbal inductive reasoning, as well as contributions and limitations of SINC and directions for future research. Overall, the authors disagree with Heit and Hayes's analysis of limitations of SINC and with their analysis of SINC in the context of verbal inductive reasoning. At the same time, the authors agree that more research is needed to provide a unified account of similarity, induction, categorization, and recognition.

Mediating political subjectivities: infrastructure, mobility, and social action in Egypt's Nile delta
Creators: name: El-Kouny, Nada
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation captures the story of materially embedded political mobilization histories in Egypt. However, the story does not emerge from the revolutionary urban centers, as was the popularly and scholarly mediated experience of the January 25, 2011 Revolution. Studied from the Nile Delta vantage point, this dissertation brings together two villages in two different governorates, al-Beheira and al-Daqahliya, located one-hundred-and-eighty kilometers apart. The villages tell the story of state development, neglect, and community mobility as enacted, mediated, and contested through infrastructure. Infrastructure is a means of not just navigating physical space but is also a way of organizing everyday life, materially—through roads, bridges, irrigation networks, and affectively—through political mobilization, connection-building, and customary rural governance structures. These infrastructural instantiations are embedded in the material histories and built environments of where citizens emerge from. The history of one of the villages of my research, Tahseen, is directly indebted to 1952 independence that brought President Gamal Abdel-Nasser to power, yet the village launched a secession movement from its municipal government in 2012, six decades after its creation. The second village of research, Nebeira, is also shaped by the history of 1952 through the process of the Nasser government’s land reform. In this dissertation I argue how the everyday experience of politics between citizens and the multiple state bodies emerges infrastructurally. Infrastructure is both material and social—it is a site where politics are mediated and a site where people reproduce the social infrastructure that organizes their lives.

Genuine Distributed Coherence

description: We introduce a notion of genuine distributed coherence. Such a notion is based on the possibility of concentrating on individual systems the coherence present in a distributed system, by making use of incoherent unitary transformations. We define an entropic quantifier of genuine distributed multipartite coherence for generic mixed states, and we focus on the bipartite pure-state case. In the latter case we derive necessary and sufficient conditions for the possibility of fully localizing the coherence, hence identifying the conditions for genuine distributed bipartite coherence. We analyze in detail the quantitative problem for the case of two-qubit pure states, identifying the states with the largest amount of genuine distributed coherence. Interestingly, such states do not have maximal global coherence nor maximal coherence rank.

description: The patterns of disease caused by five common viruses which infect the respiratory tract are described. The viruses were strains of rhinovirus types 2, 9, and 14, a strain of coronavirus type 229E and of respiratory syncytial virus. Volunteers were given nasal drops containing a low infections dose of one of the viruses, quarantined from 2 days before to 5 days after inoculation, and examined daily by a clinician using a standard checklist of respiratory signs and symptoms. Only subjects who developed clinical illness accompanied by viral shedding and/or specific antibody production were analysed [n = 116]. The results confirm indication from earlier studies that the main difference between colds induced by different viruses is in duration of the incubation period. Patterns of symptom development were not substantially different with different viruses. Analyses of signs and symptoms in different categories, e.g. nasal symptoms v. coughing, justify treatment with different drugs either successively or simultaneously.

description: We propose a probabilistic way for reducing the cost of classical projection-based model order reduction methods for parameter-dependent linear equations. A reduced order model is here approximated from its random sketch, which is a set of low-dimensional random projections of the reduced approximation space and the spaces of associated residuals. This approach exploits the fact that the residuals associated with approximations in low-dimensional spaces are also contained in low-dimensional spaces. We provide conditions on the dimension of the random sketch for the resulting reduced order model to be quasi-optimal with high probability. Our approach can be used for reducing both complexity and memory requirements. The provided algorithms are well suited for any modern computational environment. Major operations, except solving linear systems of equations, are embarrassingly parallel. Our version of proper orthogonal decomposition can be computed on multiple workstations with a communication cost independent of the dimension of the full order model. The reduced order model can even be constructed in a so-called streaming environment, i.e., under extreme memory constraints. In addition, we provide an efficient way for estimating the error of the reduced order model, which is not only more efficient than the classical approach but is also less sensitive to round-off errors. Finally, the methodology is validated on benchmark problems.

description: The (abelian bosonic) heterotic string effective action, equations of motion and Bianchi identity at order alpha prime in ten dimensions, are shown to be equivalent to a higher dimensional action, its derived equations of motion and Bianchi identity. The two actions are the same up to the gauge fields: the latter are absorbed in the higher dimensional fields and geometry. This construction is inspired by heterotic T-duality, which becomes natural in this higher dimensional theory. We also prove the equivalence of the heterotic string supersymmetry conditions with higher dimensional geometric conditions. Finally, some known Kahler and non-Kahler heterotic solutions are shown to be trivially related from this higher dimensional perspective, via a simple exchange of directions. This exchange can be encoded in a heterotic T-duality, and it may also lead to new solutions.

description: The widely used Double-Exchange model for manganites is shown to support various "striped" phases at filling fractions 1/n (n=3, 4, 5...), in the previously unexplored regime of narrow bandwidth and small Jahn-Teller coupling. Working in two dimensions, our main result is that these stripes can be individually spin flipped without a physically relevant change in the energy, i.e., we find a large groundstate manifold with nearly degenerate energies. The two-dimensional spin system thus displays an unexpected dynamically generated dimensional reduction into decoupled one-dimensional stripes, even though the electronic states remain two-dimensional. Relations of our results with recent literature addressing compass models in quantum computing are discussed.

description: Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according to which sequence information is encoded through sustained patterns of activation within a recurrent neural network architecture. As demonstrated through a series of computer simulations, the model provides a parsimonious account for numerous benchmark characteristics of immediate serial recall, including data that have been considered to preclude the application of recurrent neural networks in this domain. Unlike most competing accounts, the model deals naturally with findings concerning the role of background knowledge in serial recall and makes contact with relevant neuroscientific data. Furthermore, the model gives rise to numerous testable predictions that differentiate it from competing theories. Taken together, the results presented indicate that recurrent neural networks may offer a useful framework for understanding short-term memory for serial order.

At excitation irradiance of 20 GW/cm2, AgInSe2 NRs reveal saturation in the nonlinear absorption and optical Kerr nonlinearity with a recovery time determined to be a few ten picoseconds. Such large saturable absorption and Kerr nonlinearity exhibit a third-order susceptibility of 1.2 x 10-8 esu and a figure of merit of 0.04 esu.cm.s-1, making AgInSe2 NRs a promising candidate for saturable absorption devices.

Stronger Quantum Correlations with Loophole-free Post-selection

Year: 2011

description: One of the most striking non-classical features of quantum mechanics is in the correlations it predicts between spatially separated measurements. In local hidden variable theories, correlations are constrained by Bell inequalities, but quantum correlations violate these. However, experimental imperfections lead to "loopholes" whereby LHV correlations are no longer constrained by Bell inequalities, and violations can be described by LHV theories. For example, loopholes can emerge through selective detection of events. In this letter, we introduce a clean, operational picture of multi-party Bell tests, and show that there exists a non-trivial form of loophole-free post-selection. Surprisingly, the same post-selection can enhance quantum correlations, and unlock a connection between non-classical correlations and non-classical computation.

description: T cell receptors (TCRs) bind foreign or self-peptides attached to major histocompatibility complex (MHC) molecules, and the strength of this interaction determines T cell activation. Optimizing the ability of T cells to recognize a diversity of foreign peptides yet be tolerant of self-peptides is crucial for the adaptive immune system to properly function. This is achieved by selection of T cells in the thymus, where immature T cells expressing unique, stochastically generated TCRs interact with a large number of self-peptide-MHC; if a TCR does not bind strongly enough to any self-peptide-MHC, or too strongly with at least one self-peptide-MHC, the T cell dies. Past theoretical work cast thymic selection as an extreme value problem, and characterized the statistical enrichment or depletion of amino acids in the post-selection TCR repertoire, showing how T cells are selected to be able to specifically recognize peptides derived from diverse pathogens, yet have limited self-reactivity. Here, we investigate how the degree of enrichment is modified by nonuniform contacts that a TCR makes with peptide-MHC. Specifically, we were motivated by recent experiments showing that amino acids at certain positions of a TCR sequence have large effects on thymic selection outcomes, and crystal structure data that reveal a nonuniform contact profile between a TCR and its peptide-MHC ligand. Using a representative TCR contact profile as an illustration, we show via simulations that the degree of enrichment now varies by position according to the contact profile, and, importantly, it depends on the implementation of nonuniform contacts during thymic selection. We explain these nontrivial results analytically. Our study has implications for understanding the selection forces that shape the functionality of the post-selection TCR repertoire.

description: Although widespread alterations in cortical structure have been documented in individuals with autism, the functional implications of these alterations remain to be determined. Here, we adopted a novel inter-subject correlation (inter-SC) and intra-subject correlation (intra-SC) technique to quantify the reliability of the spatio-temporal responses of functional MR activity in adults with autism during free-viewing of a popular audio–visual movie. Whereas these complex stimuli evoke highly reliable shared response time courses in typical individuals, cortical activity was more variable across individuals with autism (low inter-SC). Interestingly, when we measured the responses within an autistic individual across repeated presentations of the movie, we observed a unique, idiosyncratic response time course that was reliably replicated within each individual (high intra-SC). Encouragingly, after filtering out the idiosyncratic responses from each individual time course, we were able to uncover a more typical response profile, which resembles the shared responses seen in the typical subjects. These findings indicate that, under conditions approximating real-life situations, the neural activity of individuals with autism is characterized by individualistic responses that, although reliable within an autistic individual, are both highly variable across autistic individuals and different from the responses observed within the typical subjects. These idiosyncratic responses may underlie the atypical behaviors observed in autism. At the same time, we are encouraged by the presence of the more typical activation pattern lurking beneath these idiosyncratic fluctuations. Taken together, these findings may pave the way to future research aimed at characterizing the idiosyncratic response profiles, which, in turn, might contribute to a better understanding of the heterogeneity of the autism spectrum and its diagnosis.

description: BGP communities are a mechanism widely used by operators to manage policy, mitigate attacks, and engineer traffic; e.g., to drop unwanted traffic, filter announcements, adjust local preference, and prepend paths to influence peer selection. Unfortunately, we show that BGP communities can be exploited by remote parties to influence routing in unintended ways. The BGP community-based vulnerabilities we expose are enabled by a combination of complex policies, error-prone configurations, a lack of cryptographic integrity and authenticity over communities, and the wide extent of community propagation. Due in part to their ill-de ned semantics, BGP communities are often propagated far further than a single routing hop, even though their intended scope is typically limited to nearby ASes. Indeed, we find 14% of transit ASes forward received BGP communities onward. Given the rich inter-connectivity of transit ASes, this means that communities effectively propagate globally. As a consequence, remote adversaries can use BGP communities to trigger remote blackholing, steer traffic, and manipulate routes even without pre x hijacking. We highlight examples of these attacks via scenarios that we tested and measured both in the lab as well as in the wild. While we suggest what can be done to mitigate such ill effects, it is up to the Internet operations community whether to take up the suggestions.

description: The detection of GW170817 and its electromagnetic counterparts allows to constrain the equation of state of dense matter in new and complementary ways. Very stiff equations of state are ruled out by the upper limit on the average tidal deformability, $\tildeΛ\lesssim 800$, imposed by the detected gravitational wave signal. A lower limit, $\tildeΛ\gtrsim 400$, can also be extracted by considering the large amount of ejected matter which powers the kilonova AT2017gfo. By using several microscopic nucleonic equations of state, we first confirm the existence of a monotonic relation between $R_{1.5}$ (the radius of the $1.5M_{\odot}$ configuration) and $\tildeΛ$. This translates the limits on $\tildeΛ$ into limits on the radius: $11.8\,\text{km} \lesssim R_{1.5} \lesssim 13.1\,$km. We then show that the monotonic relation is violated, if a second branch of compact stars composed of quark matter exists, as in the two-families or the twin-stars scenarios. In particular, it is possible to fulfill the limits on $\tildeΛ$ while having $R_{1.5}$ significantly smaller than $12\,$km. In both those scenarios the event GW170817/AT2017gfo originates from the merger of a hadronic star and a star containing quark matter.

description: We study the effect of quasar feedback on distributions of baryons and properties of intracluster medium in galaxy groups using high-resolution numerical simulations. We use the entropy-conserving Gadget code that includes gas cooling and star formation, modified to include a physically-based model of quasar feedback. For a sample of ten galaxy group-sized dark matter halos with masses in the range of 1 to $5\times 10^{13} M_{\odot}/h$, star formation is suppressed by more than 50% in the inner regions due to the additional pressure support by quasar feedback, while gas is driven from the inner region towards the outer region of the halos. As a result, the average gas density is 50% lower in the inner region and 10% higher in the outer region in the simulation, compared to a similar simulation with no quasar feedback. Gas pressure is lowered by about 40% in the inner region and higher in the outer region, while temperature and entropy are enhanced in the inner region by about 20-40%. The total group gas fraction in the two simulations generally differs by less than 10%. We also find a small change of the total thermal Sunyaev-Zeldovich distortion, leading to 10% changes in the microwave angular power spectrum at angular scales below two arcminutes.

description: Beam-column joints are crucial structural components to ensure the overall stability of reinforced concrete framed structures subjected to seismic loads. A number of research efforts have been devoted to enhance the seismic behavior of beam-column joints. The current codes for reinforced concrete structures requires high amount of transverse reinforcement in joint panel zone to avoid the premature failure of the joint region. However, the main challenge facing these code-based solutions is the use of high amount of closely spaced transverse reinforcements in the beam-column joints leads to abrupt and unpreventable concrete crushing failure. In this study, the behavior of exterior beam-column joints with normal concrete and steel fiber reinforced concrete have been investigated. The main aim of this study is to investigate the use of steel fiber reinforced concrete in reducing the transverse reinforcements in beam-column joint and to explore the influence of varation of column axial loads on steel fiber reinforced concrete beam-column joints under cyclic loading. Nonlinear finite element method with the damaged plasticity model for both normal concrete and steel fiber reinforced concrete in ABAQUS/Standard is adopted to simulate the beam-column joints. The accuracy of the nonlinear finite element models are verified using experimental results conducted by other researchers. Then, an adequate shear reinforced concrete specimen is selected from the validated specimens for a control specimen. A total of nineteen specimens are simulated by varying the volume fraction of steel fiber of 1%, 1.5% and 2% coupling with the reduction of transverse reinforcements in joint from the control specimen and variation of column axial loads. The analysis results revealed that addition of 1%, 1.5% and 2% volume fraction of steel fiber in concrete could effectively accommodate up to 33%, 67% and 100% reduction of transverse reinforcement in beam-column joints, respectively. These results confirmed that the appropriate use of steel fiber in concrete can be a feasible solution to solve the reinforcement congestion problem and improve the joint’s seismic performance. Moreover, an increase of axial load up to 50% of the column capacity improves the crack resistance of steel fiber reinforced concrete joints, however, further increases of axial loads reduce the joints performance due to local crushing of concrete.

description: The measured value of the Higgs quartic coupling $λ$ is peculiarly close to the critical value above which the Higgs potential becomes unstable, when extrapolated to high scales by renormalization group running. It is tempting to speculate that there is an anthropic reason behind this near-criticality. We show how an axionic field can provide a landscape of vacuum states in which $λ$ scans. These states are populated during inflation to create a multiverse with different quartic couplings, with a probability distribution $P$ that can be computed. If $P$ is peaked in the anthropically forbidden region of Higgs instability, then the most probable universe compatible with observers would be close to the boundary, as observed. We discuss three scenarios depending on the Higgs vacuum selection mechanism: decay by quantum tunneling; by thermal fluctuations or by inflationary fluctuations.

description: Concrete is a type of artificial stone which can be produced by a mixture of aggregate,
 water, and cement. There are various types of concrete can be found in the market due to
 the desired structural properties. Lightweight concrete (LWC) is one of the most
 important types of concrete owing to its unit weight and insulation properties against
 temperature and voice. Structural Lightweight aggregate concretes are widely
 incorporated in construction and development. This study, presents an experimental
 Work on the Structural Lightweight concrete by partial Replacement of Coarse
 Aggregate by volcanic pumice. For C-25 grade concrete by replacement weight
 percentages of 10, 20, 30 and 40%, Coarse Aggregate by volcanic pumice. The use of
 structural grade light weight concrete reduces the self-weight and helps to construct
 larger structural units. In our country there is the sacristy of land especially in large city.
 So we have to adopt the SLWC to construct high rise building for accommodation of
 money people in one place. For this purpose along with a Control Mix, 12 cubes
 15cm*15cm*15cm size, sets were prepared. Slump test were carried out for each mix in
 the fresh state and also, 7days and 28-days Compressive strength, split tensile strength
 and Flexural tensile strength tests were performed in the hardened state. According to
 ACI 213 (SLWC) made with lightweight aggregate; the unit weight at 28 days is between
 1440kg/m3 to1850 kg/m3 and the compressive strength is more than 17.2 MPa. So this
 study result will shows the compressive strength of 0%, 10%, 20%, 30% and 40% fulfills
 its requirements. But not for the density. In other word according to ASTEM C 496 and
 (ACI 318) the minimum splitting tensile strength of lightweight concrete is 2.0MPa so
 the outcomes of our study all of it fulfill its requirements.

description: Objective To examine sex differences in the relation of childhood socioeconomic status (CSES) to systolic (SBP) and diastolic blood pressure (DBP) trajectories during 15 years, spanning young (mean [M] [standard deviation {SD}] = 30 [3] years) and middle (M [SD] = 45 [3] years) adulthood, independent of adult SES. Methods A total of 4077 adult participants reported father’s and mother’s educational attainments at study enrollment (Year 0) and own educational attainment at enrollment and at all follow-up examinations. Resting BP also was measured at all examinations. Data from examination Years 5 (when participant M [SD] age = 30 [3] years), 7, 10, 15, and 20 are examined here. Associations of own adult (Year 5), mother’s, and father’s educations with 15-year BP trajectories were examined in separate multilevel models. Fully controlled models included time-invariant covariates (age, sex, race, recruitment center) and time-varying covariates that were measured at each examination (marital status, body mass, cholesterol, oral contraceptives/hormones, and antihypertensive drugs). Analyses of parental education controlled for own education. Results When examined without covariates, higher education — own (SBP γ = −0.03, DBP γ = −0.03), mother’s (SBP γ = −0.02, DBP γ = −0.02), and father’s (SBP γ = −0.02, DBP γ = −0.01) — were associated with attenuated 15-year increases in BP (p < .001). Associations of own (but not either parent’s) education with BP trajectories remained independent of standard controls. Sex moderated the apparent null effects of parental education, such that higher parental education—especially mother’s, predicted attenuated BP trajectories independent of standard covariates among women (SBP γ = −0.02, p = .02; DBP γ = −0.01, p = .04) but not men (SBP γ = 0.02, p = .06; DBP γ = 0.005, p = .47; p interaction SBP < .001, p interaction DBP = .01). Conclusions Childhood socioeconomic status may influence women’s health independent of their own adult status.
