description: The third annual conference of Empowering Women of Color (EWOC), Double-Consciousness: Women of Color as Advocates for Ourselves and Others, gathered law students, practitioners, and academics together to discuss and strategize around double- consciousness as a phenomenon shared among women lawyers of color yet unique to each person’s idiosyncratic and multi-faceted identities. The conference sought to address ever- present questions of balance: How do we balance our reality as private citizens who are subject to the law with our role as advocates armed with the power of the law? How do we balance our individual professional pursuits with the quest for collective advancement of our identity groups in society?

description: We discuss the issue of setting appropriate initial conditions for inflation. Specifically, we consider natural inflation model and discuss the fine tuning required for setting almost homogeneous initial conditions over a region of order several times the Hubble size which is orders of magnitude larger than any relevant correlation length for field fluctuations. We then propose to use the special propagating front solutions of reaction-diffusion equations for localized field domains of smaller sizes. Due to very small velocities of these propagating fronts we find that the inflaton field in such a ${\it field domain}$ changes very slowly, contrary to naive expectation of rapid roll down to the true vacuum. Continued expansion leads to the energy density in the Hubble region being dominated by the vacuum energy, thereby beginning the inflationary phase. Our results show that inflation can occur even with a single localized field domain of size smaller than the Hubble size. We discuss possible extensions of our results for different inflationary models, as well as various limitations of our analysis (e.g. neglecting self gravity of the localized field domain).

description: While American public education once stood as an example of educational excellence globally, it now exists as only a shell of what it once was. Students from countries across the globe now routinely outperform American children and as each year passes, students filling classrooms in the United States slip farther and farther behind their international peers. American student proficiency rates across all subject areas sit at such low levels that they call into serious the question the creation of a competent and efficient workforce prepared to address and correct the varied problems the nation faces as it begins the 21st century. While numerous factors have contributed to this eroding of American education, one factor of significant influence is the practice of collective bargaining by teachers' unions with school districts, as it exists today. Though unions and collective bargaining serve an important role in American public education, protecting the interests of teachers and ensuring fair employment standards for these professionals, many aspects of these agreements between unions and school districts give short shrift to their negative implications for the students these teachers hope to educate. The goal of this Note is to demonstrate the negative effects collective bargaining has had and continues to have on student achievement in America's public schools, flesh out the problematic areas within these agreements, and put forth suggestions as to how the practice of collective bargaining might be modified to better serve American children, those on whom the public education should be principally focused.

description: The history of marriage has been one of evolution, not of static immutability, with marriage surviving innumerable changes to its core rules over the last two centuries. These changes to the institution of marriage over time have rendered the current rule excluding same-sex couples from marriage inconsistent with New York law, which has both repudiated gendered marriage rules as unconstitutional and, historically as well as contemporarily, not held procreation to be an essential element of marriage. The City's gender- and procreation-related defenses thus lack any legitimate relationship to the concerns of equality and interdependence that are marriage's now-settled underpinnings. Likewise, the historical and ongoing absence of uniformity between marriage rules of New York and other states demonstrates that claims about uniformity cannot support the rule challenged here.

description: We consider a stationary queueing process $Q_X$ fed by a centered Gaussian process $X$ with stationary increments and variance function satisfying classical regularity conditions. A criterion when, for a given function $f$, $\mathbb P (Q_{X}(t) > f(t)\, \text{ i.o.})$ equals 0 or 1 is provided. Furthermore, an Erdös-Révész type law of the iterated logarithm is proven for the last passage time $ξ(t) = \sup\{s:0\le s\le t, Q_{X}(s)\ge f(s)\}$. Both of these findings extend previously known results that were only available for the case when $X$ is a fractional Brownian motion.

description: We construct models of inflation with many randomly interacting fields and use these to study the generation of cosmological observables. We model the potentials as multi-dimensional Gaussian random fields (GRFs) and identify powerful algebraic simplifications that, for the first time, make it possible to access the manyfield limit of inflation in GRF potentials. Focussing on small-field, slow-roll, approximate saddle-point inflation in potentials with structure on sub-Planckian scales, we construct explicit examples involving up to 100 fields and generate statistical ensembles comprising of 164,000 models involving 5 to 50 fields. For the subset of these that support at least sixty e-folds of inflation, we use the 'transport method' and $δN$ formalism to determine the predictions for cosmological observables at the end of inflation, including the power spectrum and the local non-Gaussianities of the primordial perturbations. We find three key results: i) Planck compatibility is not rare, but future experiments may rule out this class of models; ii) In the manyfield limit, the predictions from these models agree well with, but are sharper than, previous results derived using potentials constructed through non-equilibrium Random Matrix Theory; iii) Despite substantial multifield effects, non-Gaussianities are typically very small: $f_{\rm nl}^{\rm loc} \ll 1$. We conclude that many of the 'generic predictions' of single-field inflation can be emergent features of complex inflation models.

description: About 200 landslides and debris flows occurred in Northern Kyushu during heavy rain at Asakura City, Toho Village, Hita City on July 5th to 6th, 2017. At Hita City, the total precipitation during this two-day event was 402.5 mm. At Asakura city, underlain by granitic rocks and schist, shallow landslides dominated. Whereas, at Toho Village and Hita City, which is underlain by volcanic rocks, the number of landslides and debris flows are fewer, are larger and deeper, than those at Asakura City. We examined the geomorphology and geology at 19 landslides in volcanic rocks, 11 of which mobilized as debris flows. We studied the initiation mechanism of landslides underlain by volcanic rocks. The geology consists of pyroclastic rocks and lava flows in ascending order. The lava flows are distributed at ridges and contain vertical cooling joints. Scarps of landslides caused by the 2017 rain are located near the boundary of pyroclastic rocks and lava flows. The sliding surfaces of these landslides are at the contact between the lava flows and the pyroclastic rocks. We consider, therefore, that the trigger for these landslides was a decrease of strength at the contact caused by an increase in groundwater pressure caused by infiltration of rain water through the cooling joints in lava flows. Therefore, we conclude that the landslides caused by the 2017 heavy rain at volcanic rock fields are cap rock type landslide. Furthermore, the curvature of the hillsides downslope from landslides is concave, which may be a required condition for debris-flow mobilization.

description: To realize long-distance quantum communication and quantum network, it is required to have multiplexed quantum memory with many memory cells. Each memory cell needs to be individually addressable and independently accessible. Here we report an experiment that realizes a multiplexed DLCZ-type quantum memory with 225 individually accessible memory cells in a macroscopic atomic ensemble. As a key element for quantum repeaters, we demonstrate that entanglement with flying optical qubits can be stored into any neighboring memory cells and read out after a programmable time with high fidelity. Experimental realization of a multiplexed quantum memory with many individually accessible memory cells and programmable control of its addressing and readout makes an important step for its application in quantum information technology.

description: A hypergeometric type equation satisfying certain conditions defines either a finite or an infinite system of orthogonal polynomials. The associated special functions are eigenfunctions of some shape invariant operators. These operators can be analysed together and the mathematical formalism we use can be extended in order to define other shape invariant operators. All the considered shape invariant operators are directly related to Schrodinger type equations.

description: In spite of the high potential of endohedral metallofullerenes (EMFs) for application in biology, medicine and molecular electronics and recent efforts in EMF synthesis, the variety of EMFs accessible by conventional synthetic methods remains limited and does not include, for example, EMFs of late transition metals. We propose a method in which EMF formation is initiated by electron irradiation in aberration-corrected high-resolution transmission electron spectroscopy (AC-HRTEM) of a metal cluster surrounded by amorphous carbon inside a carbon nanotube serving as a nano-reactor and apply this method for synthesis of nickel EMFs. The use of ACHRTEM makes it possible not only to synthesize new, previously unattainable nanoobjects but also to study in situ the mechanism of structural transformations. Molecular dynamics simulations using the state-of-the-art approach for modeling the effect of electron irradiation are performed to rationalise the experimental observations and to link the observed processes with conditions of bulk EMF synthesis.

description: Detection of adulteration in carbohydrates rich foods like fruit juices is particularly difficult because of the variety of the commercial sweeteners available that match the concentration profiles of the major carbohydrates in the foods. In present study, a new sensitive and robust assay using Fourier Transform Near Infrared Spectroscopy (FT-NIRS) combined with partial least square (PLS) multivariate methods has been developed for detection and quantification of saccharin adulteration in different commercial fruit juice samples. For this investigation 6 different commercially available fruit juice samples were intentionally-adulterated with saccharin at the following percentage levels: 0 %, 0.10 %, 0.30 %, 0.50 %, 0.70 %, 0.90 %, 1.10 %, 1.30 %, 1.50 %, 1.70 % and 2.00 % (weight/volume). Altogether 198 samples were used including 18 pure juice samples (un-adulterated) and 180 juice samples adulterated with saccharin. PLS multivariate methods including partial least-squares discriminant analysis (PLS-DA), and partial least-squares regressions (PLSR) were applied to the obtained spectral data to build models. The PLSDA model was employed to differentiate between pure fruit juice samples and those adulterated with saccharin. The R2 value obtained for the PLS-DA model was 97.90 % with an RMSE error of 0.67 %. Similarly, a PLS regression model was also developed to quantify the amount of saccharin adulterant in juice samples. The R2 value obtained for the PLSR model was 97.04 % with RMSECV error of 0.88 %. The employed model was then cross-validated by using a test set which included 30 % of the total adulterated juice samples. The excellent performance of the model was proved by the low RMSEP value of 0.92 % and the high correlation factor of 0.97. This newly developed method is robust, non-destructive, highly sensitive, and economical.

description: In several situations, most notably when describing metastable states, a system can evolve according to an effective non hermitian Hamiltonian. To each eigenvalue of a non hermitian Hamiltonian is associated an eigenstate $\vertϕ\rangle$ which evolves forward in time and an eigenstate $\langleψ\vert$ which evolves backward in time. Quantum measurements on such systems are analyzed in detail with particular emphasis on adiabatic measurements in which the measuring device is coupled weakly to the system. It is shown that in this case the outcome of the measurement of an observable $A$ is the weak value $\langleψ\vert A\vertϕ\rangle / \langleψ\vertϕ\rangle $ associated to the two-state vector $\langleψ\vert$ $\vertϕ\rangle$ corresponding to one of the eigenvalues of the non hermitian Hamiltonian. The possibility of performing such measurements in a laboratory is discussed.

description: A method for calculating the electronic levels in the compact superheavy nuclear quasi-molecules, based on solving the two-center Dirac equation using the multipole expansion of two-center potential, is developed. For the internuclear distances up to $d\sim100$~fm such technique reveals a quite fast convergence and allows for computing the electronic levels in such systems with accuracy $\sim 10^{-6} $. The critical distances $R_{cr}$ between the nuclei for $1σ_g$ and $1σ_u$ electronic levels in the region $Z\simeq 87-100$ are calculated. By means of the same technique the shifts of electronic levels due to the effective interaction $ΔU_{AMM}$ of the electron's magnetic anomaly with the Coulomb field of the closely spaced heavy nuclei are evaluated as a function of the internuclear distance and the charge of the nuclei, non-perturbatively both in $Zα$ and (partially) in $α/π$. It is shown, that the levels shifts near the lower continuum decrease with the enlarging size of the system of Coulomb sources both in the absolute units and in units of $Z^4 α^5 / πn^3$. The last result is generalized to the whole self-energy contribution to the level shifts and so to the possible behavior of radiative part of QED-effects with virtual photon exchange near the lower continuum in the overcritical region.

description: The SAGE2 project is a collaboration between industry, data centres and research institutes demonstrating an exascale-ready system based on layered hierarchical storage and a novel object storage technology. The development of this system is based on a significant co-design exercise between all partners, with the research institutes having well established needs for exascale computing systems, both in terms of compute (exaFLOPS) and storage (exaBytes). In this paper we present an overview of the system design concepts and introduce some of the features of the object storage system which have the potential to make applications more efficient and simpler to use. The physical realisation of a prototype, hosted at Forschungszentrum Jülich is also detailed showing in detail the layered hierarchy We also present a case study of applications which have already been ported, covering issues uncovered and how these have been addressed in the codesign proves. Finally, we look at how this suite of applications are being extended into different regimes including machine learning to address a wider range of use cases and how interfaces are being developed to allow integration with other architectures

description: Detailed surface photometry for 79 (mostly dwarf) galaxies in the NGC 5044 Group area is analysed, revealing the existence of different morphologies among objects originally classified as early-type dwarfs. Particularly, a significant fraction of bright dwarf "ellipticals" show a distinct bulge+disc structure; we thus re-classify these objects as dwarf lenticulars (dS0). Our finding points at a possible scenario where these systems are the remnants of "harassed" disc galaxies. This is emphasized by the discovery of a few objects with hints for very low-surface brightness spiral-like structure. The colours, structure, and spatial distribution of the different galaxy types suggest that our classification may indeed be separating objects with different origins and/or evolutionary paths.

In this paper, we give an algebraic proof of the renormalizability of the resulting action to all orders in perturbation theory.

description: This study evaluates the relationship between shape and size of tegmen, harp, mirror, and spectral range of calling song frequency of a Neotropical cricket subpopulation (Lerneca inalata beripocone. In addition, we compare intraspecific morphological divergence and calling song properties between individuals from different sites of the Pantanal of Poconé, Mato Grosso, Brazil. Regression analysis showed that the dominant and maximum calling song frequencies were negatively correlated with tegmen size, i.e. frequencies are either lower or higher depending on the corresponding size variation in resonance structures of the forewings. Canonical variable analysis demonstrated marked intraspecific differences in morphometric characters between localities of a L. inalata subpopulation c. 35 km apart (SESC-Pantanal Advanced Research Base and Pouso Alegre Farm, Mato Grosso, Brazil). Lerneca inalata beripocone at SESC had larger forewings than conspecifics from Pouso Alegre Farm. These morphological variations of wing properties related to reproductive behaviours were interpreted as fitness parameters, likely shaped by restricted gene flow during temporal habitat isolation episodes. Such isolation patterns occur in the Pantanal wetlands for several months during the annual hydrological cycle.

description: We report calculations of the superfluid pairing gap in neutron matter for the $^1S_0$ components of the Reid soft-core $V_6$ and the Argonne $V_{4}'$ two-nucleon interactions. Ground-state calculations have been carried out using the central part of the operator-basis representation of these interactions to determine optimal Jastrow-Feenberg correlations and corresponding effective pairing interactions within the correlated-basis formalism (CBF), the required matrix elements in the correlated basis being evaluated by Fermi hypernetted-chain techniques. Different implementations of the Fermi-Hypernetted Chain Euler-Lagrange method (FHNC-EL) agree at the percent level up to nuclear matter saturation density. For the assumed interactions, which are realistic within the low density range involved in $^1S_0$ neutron pairing, we did not find a dimerization instability arising from divergence of the in-medium scattering length, as was reported recently for simple square-well and Lennard-Jones potential models (Phys. Rev. A {\bf 92}, 023640 (2015)).

description: Two-dimensional random surfaces are studied numerically by the dynamical triangulation method. In order to generate various kinds of random surfaces, two higher derivative terms are added to the action. The phases of surfaces in the two-dimensional parameter space are classified into three states: flat, crumpled surface, and branched polymer. In addition, there exists a special point (pure gravity) corresponding to the universal fractal surface. A new probe to detect branched polymers is proposed, which makes use of the minbu(minimum neck baby universe) analysis. This method can clearly distinguish the branched polymer phase from another according to the sizes and arrangements of baby universes. The size distribution of baby universes changes drastically at the transition point between the branched polymer and other kind of surface. The phases of surfaces coupled with multi-Ising spins are studied in a similar manner.

Fast and Efficient Entropy Compression of ALICE Data using ANS Coding
Creators: name: Lettrich, Michael
Publisher: name: Zenodo
Year: 2019

description: With the beginning of LHC Run 3, the upgraded ALICE detector will record Pb-Pb collisions at an interaction rate of 50 kHz using continuous readout, resulting in raw data rates of over 3.5TB/s marking a hundredfold increase over Run 2. Since permanent storage at this rate is unfeasible and exceeds available capacities, a sequence of highly effective compression and data reduction steps is required. Most of these steps perform lossy compression based on techniques like zero suppression, track finding and clusterization without affecting physics. The final compression step is the lossless entropy encoding. Huffman coding as used for entropy coding in Run 2 is fast and simple, but suffers from an inefficiency of up to one bit per encoded symbol compared to the entropy, leaving room for optimization. For Run 3 entropy coding based on asymmetric numeral systems (ANS) is under evaluation. ANS achieves compression by encoding source symbols into a single, infinite precision integer state variable using arithmetic operations based on a symbols probability, thus overcoming the one bit inefficiency of Huffman coders. This allows for compression ratios very close to the entropy. Furthermore the mathematical properties of ANS allow efficient parallelization using vector units on CPUs or GPUs. This contribution describes a custom implementation of an ANS encoder and decoder required to cope with the various distributions of source data that have to be taken into account to achieve the desired high compression ratios for the ALICE detectors - in particular the Time Projection Chamber (TPC) and the Inner Tracking System (ITS). To ensure encoding bandwidth is on pair with the high data rates, our implementation leverages SIMD vector units of CPUS and on-GPU data compression is under evaluation.

description: During the last few years, the EOS distributed storage system at CERN has seen a steady increase in use, both in terms of traffic volume as well as sheer amount of stored data. This has brought the unwelcome side effect of stretching the EOS software stack to its design constraints, resulting in frequent user-facing issues and occasional downtime of critical services. In this paper, we discuss the challenges of adapting the software to meet the increasing demands, while at the same time preserving functionality without breaking existing features or introducing new bugs. We document our efforts in modernizing and stabilizing the codebase, through the refactoring of legacy code, introduction of widespread unit testing, as well as leveraging kubernetes to build a comprehensive test orchestration framework capable of stressing every aspect of an EOS installation, with the goal of discovering bottlenecks and instabilities before they reach production.

description: We use likelihood informed dimension reduction (LIS) (T. Cui et al. 2014) for inverting vertical profile information of atmospheric methane from ground based Fourier transform infrared (FTIR) measurements at Sodankylä, Northern Finland. The measurements belong to the word wide TCCON network for greenhouse gas measurements and, in addition to providing accurate greenhouse gas measurements, they are important for validating satellite observations. LIS allows construction of an efficient Markov chain Monte Carlo sampling algorithm that explores only a reduced dimensional space but still produces a good approximation of the original full dimensional Bayesian posterior distribution. This in effect makes the statistical estimation problem independent of the discretization of the inverse problem. In addition, we compare LIS to a dimension reduction method based on prior covariance matrix truncation used earlier (S. Tukiainen et al. 2016).

description: 1. Tris(4-chlorophenyl)methane (TCPME) and Tris(4-chlorophenyl)methanol (TCPMOH) have been detected in various biota and human tissues. 2. The current studies were undertaken to investigate the disposition and metabolism of TCPME and TCPMOH in rats and mice. 3. [14C]TCPME was well absorbed (≥ 66%) in male rats and mice following a single oral administration of 1, 10, or 100 mg/kg. The excretion of [14C]TCPME-derived radioactivity in urine (≤ 2.5%) and feces (≤18%) was low. The administered dose was retained in tissues (≥ 64%) with adipose containing the highest concentrations. The metabolism of TCPME was minimal. The disposition and metabolism of [14C]TCPME in females was similar to males. 4. The time to reach maximum concentration was ≤7 h, the plasma elimination half-life was ≥ 31 h, and the bioavailability was ≥ 82% following a 10 mg/kg oral dose of [14C]TCPME in male rats and mice. 5. The disposition of [14C]TCPMOH was similar to that of [14C]TCPME. 6. Following an intravenous administration of [14C]TCPME or [14C]TCPMOH in male rats and mice, the pattern of disposition was similar to that of oral administration. 7. In conclusion, both TCPME and TCPMOH are readily absorbed and highly bioavailable following a single oral administration pointing to importance of assessing the toxicity of these chemicals.

description: We introduce an entanglement branching operator to split a composite entanglement flow in a tensor network which is a promising theoretical tool for many-body systems. We can optimize an entanglement branching operator by solving a minimization problem based on squeezing operators. The entanglement branching is a new useful operation to manipulate a tensor network. For example, finding a particular entanglement structure by an entanglement branching operator, we can improve a higher-order tensor renormalization group method to catch a proper renormalization flow in a tensor network space. This new method yields a new type of tensor network states. The second example is a many-body decomposition of a tensor by using an entanglement branching operator. We can use it for a perfect disentangling among tensors. Applying a many-body decomposition recursively, we conceptually derive projected entangled pair states from quantum states that satisfy the area law of entanglement entropy.

description: EOS is the main storage system at CERN providing hundreds of PB of capacity to both physics experiments and also regular users of the CERN infrastructure. Since its first deployment in 2010, EOS has evolved and adapted to the challenges posed by ever increasing requirements for storage capacity, user friendly POSIX-like interactive experience and new paradigms like collaborative applications along with sync and share capabilities. Overcoming these challenges at various levels of the software stack meant coming up with a new architecture for the namespace subsystem, completely redesigning the EOS FUSE module and adapting the rest of the components like draining, LRU engine, file system consistency check and others, to ensure a stable and predictable performance. In this paper we are going to detail the issues that triggered all these changes along with the software design choices that we made. In the last part of the paper, we move our focus to the areas that need immediate improvements in order to ensure a seamless experience for the end-user along with increased over-all availability of the service. Some of these changes have far reaching effects and are aimed at simplifying both the deployment model but more importantly the operational load when dealing with (non/)transient errors in a system managing thousands of disks.

Open Systems Viewed Through Their Conservative Extensions

description: A typical linear open system is often defined as a component of a larger conservative one. For instance, a dielectric medium, defined by its frequency dependent electric permittivity and magnetic permeability is a part of a conservative system which includes the matter with all its atomic complexity. A finite slab of a lattice array of coupled oscillators modelling a solid is another example. Assuming that such an open system is all one wants to observe, we ask how big a part of the original conservative system (possibly very complex) is relevant to the observations, or, in other words, how big a part of it is coupled to the open system? We study here the structure of the system coupling and its coupled and decoupled components, showing, in particular, that it is only the system's unique minimal extension that is relevant to its dynamics, and this extension often is tiny part of the original conservative system. We also give a scenario explaining why certain degrees of freedom of a solid do not contribute to its specific heat.

description: The energy source powering the extreme optical luminosity of hydrogen-stripped Superluminous Supernovae (SLSNe-I) is not known, but recent studies have highlighted the case for a central engine. Radio and/or X-ray observations are best placed to track the fastest ejecta and probe the presence of outflows from a central engine. We compile all the published radio observations of SLSNe-I to date and present three new observations of two new SLSNe-I. None were detected. Through modeling the radio emission, we constrain the sub-parsec environments and possible outflows in SLSNe-I. In this sample we rule out on-axis collimated relativistic jets of the kind detected in Gamma-Ray Bursts (GRBs). We constrain off-axis jets with opening angles of 5\arcdeg\ (30\arcdeg) to energies of $\rm{E_k<4\times10^{50}\,erg}$ ($\rm{E_k<10^{50}\,erg}$) in environments shaped by progenitors with mass-loss rates of $\dot{M}<10^{-4}\,M_{\odot}\,{\rm yr}^{-1}$ ($\dot{M}<10^{-5}\,M_{\odot}\,{\rm yr}^{-1}$) for all off-axis angles, assuming fiducial values $ε_e=0.1$ and $ε_B=0.01$. The deepest limits rule out emission of the kind seen in faint un-collimated GRBs (with the exception of GRB\,060218), and from relativistic supernovae. Finally, for the closest SLSN-I SN 2017egm we constrained the energy of an uncollimated non-relativistic outflow like those observed in normal SNe to $E_{\rm k}\lesssim10^{48}$ erg.

description: This Essay takes a fresh look at the scholarship on the practice of cross-cultural and client-centered lawyering. The current scholarship explores methods of training law students to be mindful of the ways that cultural differences can impact legal representation. However, this scholarship has not addressed how to equip students to address issues of racial discrimination in light of the post-racial lens through which many view these problems. Legal educators must examine how law students’ beliefs regarding the current relevance of race in America affects their ability to represent clients who believe they are victims of racial discrimination.
