description: This dissertation explores women's contraceptive access while incarcerated in jail. In many U.S. jails, women's hormonal contraceptive methods are discontinued and not reinitiated prior to release, and most jails do not provide women in their custody the opportunity to initiate a contraceptive method. Additionally, many women do not have access to postpartum sterilization procedures while in the custody of a jail and giving birth at a local hospital. This dissertation addresses three research questions. I answer the first research question, "What are the contraceptive needs and method preferences of women incarcerated at the Salt Lake County jail?" through a quantitative analysis of surveys completed by 194 women incarcerated at the Salt Lake County jail. I found that just over half of the participants had used contraception in the previous year. Forty-one percent of participants planned to use contraception after release, and 67% reported interest in initiating contraception in jail. Women were most interested in using condoms, IUDs, implants, the birth control shot, and the pill. Providing birth control methods in the Salt Lake County Jail could increase contraceptive use and potentially reduce the number of unintended pregnancies women experience after release. I answer the second research question, "What attitudes do incarcerated women have toward sterilization occurring while in custody?" through a qualitative analysis of transcripts from three focus groups. The majority of participants believed that sterilization should be available for incarcerated women, and they argued that an organization unaffiliated with the jail should be responsible for sterilization education and consent processes to reduce sterilization abuse. Sterilization of incarcerated women is a controversial issue and additional efforts should be made to include incarcerated women's voices in the discussion. I answer the third research question, "What mechanisms and rationales do specific jails utilize to either discontinue or continue and initiate contraceptives for women in their custody?" through a qualitative analysis of transcripts from interviews with jail health care providers working in eight different jails in the United States. Half of the providers described comprehensive contraceptive programs in their facilities, including reproductive life planning, contraceptive counseling, and the availability of a range of methods-including IUDs and implants-for women prior to release. Two providers described limited contraceptive care, and two providers described their facilities having no contraceptive care available for women. Factors associated with comprehensive contraceptive care in a facility included a "champion" who initiated the program and health care provided by a public health department.

description: Hybrid memory systems, comprised of emerging non-volatile memory (NVM) and DRAM, have been proposed to address the growing memory demand of applications. Emerging NVM technologies, such as phase-change memories (PCM), memristor, and 3D XPoint, have higher capacity density, minimal static power consumption and lower cost per GB. However, NVM has longer access latency and limited write endurance as opposed to DRAM. The different characteristics of two memory classes point towards the design of hybrid memory systems containing multiple classes of main memory.
 In the iterative and incremental development of new architectures, the timeliness of simulation completion is critical to project progression. Hence, a highly efficient simulation method is needed to evaluate the performance of different hybrid memory system designs. Design exploration for hybrid memory systems is challenging, because it requires emulation of the full system stack, including the OS, memory controller, and interconnect. Moreover, benchmark applications for memory performance test typically have much larger working sets, thus taking even longer simulation warm-up period.
 In this paper, we propose a FPGA-based hybrid memory system emulation platform. We target at the mobile computing system, which is sensitive to energy consumption and is likely to adopt NVM for its power efficiency. Here, because the focus of our platform is on the design of the hybrid memory system, we leverage the on-board hard IP ARM processors to both improve simulation performance while improving accuracy of the results. Thus, users can implement their data placement/migration policies with the FPGA logic elements and evaluate new designs quickly and effectively. Results show that our emulation platform provides a speedup of 9280x in simulation time compared to the software counterpart Gem5.
FLaapLUC: a pipeline for the generation of prompt alerts on transient Fermi-LAT $γ$-ray sources

description: The large majority of high energy sources detected with Fermi-LAT are blazars, which are known to be very variable sources. High cadence long-term monitoring simultaneously at different wavelengths being prohibitive, the study of their transient activities can help shedding light on our understanding of these objects. The early detection of such potentially fast transient events is the key for triggering follow-up observations at other wavelengths. A Python tool, FLaapLUC, built on top of the Science Tools provided by the Fermi Science Support Center and the Fermi-LAT collaboration, has been developed using a simple aperture photometry approach. This tool can effectively detect relative flux variations in a set of predefined sources and alert potential users. Such alerts can then be used to trigger target of opportunity observations with other facilities. It is shown that FLaapLUC is an efficient tool to reveal transient events in Fermi-LAT data, providing quick results which can be used to promptly organise follow-up observations. Results from this simple aperture photometry method are also compared to full likelihood analyses. The FLaapLUC package is made available on GitHub and is open to contributions by the community.

A Coherent Timing Solution for the Nearby Isolated Neutron Star RX J0720.4-3125

description: We present the results of a dedicated effort to measure the spin-down rate of the nearby isolated neutron star RX J0720.4-3125. Comparing arrival times of the 8.39-sec pulsations for data from Chandra we derive an unambiguous timing solution for RX J0720.4-3125 that is accurate to <0.1 cycles over >5 years. Adding data from XMM and ROSAT, the final solution yields Pdot=(6.98+/-0.02)x10^(-14) s/s; for dipole spin-down, this implies a characteristic age of 2 Myr and a magnetic field strength of 2.4e13 G. The phase residuals are somewhat larger than those for purely regular spin-down, but do not show conclusive evidence for higher-order terms or a glitch. From our timing solution as well as recent X-ray spectroscopy, we concur with recent suggestions that RX J0720.4-3125 is most likely an off-beam radio pulsar with a moderately high magnetic field.

The results are obtained from a data sample of 227 10^6 Y4S to BB_ decays collected with the BaBar detector at the PEP2 asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood fit yielding 111+/-19 signal events we find B(B^0 to rho^0 K^0)=(4.9+/-0.8+/-0.9) 10^-6, where the first error is statistical and the second systematic. We report the measurement of the CP parameters S=0.20+/-0.52+/-0.24 and C=0.64+/-0.41+/-0.20.

description: The Glu-Leu-Arg (ELR)(+) chemokine C-X-C ligand 1 (CXCL1) is widely known to be involved in the recruitment of neutrophils to sites of inflammation by binding to the receptor C-X-C receptor 2 (CXCR2) expressed on the surface of neutrophils. The role of neutrophils in central nervous system (CNS) diseases has not been well characterized. Thus, we wanted to better understand the role of the CXCL1/CXCR2 signaling axis in the context of mouse models of the human demyelinating disease multiple sclerosis (MS), including infection with the JHM strain of mouse hepatitis virus (JHMV) and the myelin oligodendrocyte glycoprotein (MOG) peptide from amino acid 35 to 55 (MOG35-55)-induced Experimental Autoimmune Encephalomyelitis (EAE) model. In both models, the doxycycline (Dox)-inducible expression of CXCL1 from astrocytes selectively increased the recruitment of neutrophils into the spinal cord, correlating with an increase in both morbidity and demyelination. Antibody-mediated depletion of neutrophils during the overexpression of CXCL1 in the CNS correlated with a decrease in the severity of demyelination, indicating a role for neutrophils in white matter disease in JHMV-infected mice and MOG35-55-induced EAE. During CNS development, proliferation and migration of oligodendrocyte progenitor cells (OPCs) was dependent upon surface expression of the chemokine receptor CXCR2; genetic ablation of Cxcr2 resulted in misalignments in oligodendrocyte lineage cells (OLCs), decreased white matter in the spinal cord, and decreased myelin sheath thickness. Subsequent studies have determined that CXCR2 signaling has important roles on both hematopoietic and non-hematopoietic cells in remyelination in different models of demyelination. To better determine the role the CXCR2 signaling on OLCs during the pathogenesis of JHMV and MOG35-55 EAE, mice were engineered in which CXCR2 expression was inducibly ablated on oligodendroglia upon treatment with tamoxifen. Using both the JHMV infection and EAE models, we observed no significant changes in clinical disease, demyelination, or leukocyte infiltration into the CNS following tamoxifen-induced ablation in oligodendrocytes, indicating that CXCR2 in OLCs does not appear to be important in the pathogenesis of JHMV and MOG35-55 EAE.

description: Prior to the EU Horizon 2020 and FP7 SOLARNET projects, metadata descriptions of Solar observations were only standardized for space-based observations, but the standards have been mostly within a single space mission at a time, at times with significant differences between different mission standards. In the context of ground-based Solar observations, data has typically not been made freely available to the general research community, resulting in an even greater lack of standards for metadata descriptions. This situation makes it difficult to construct multi-instrument archives/virtual observatories with anything more than the most basic metadata available for searching, as well as making it difficult to write generic software for instrument-agnostic data analysis. This document describes the metadata recommendations developed under the SOLARNET EU project, which aims foster more collaboration and data sharing between both ground-based and space-based Solar observatories. The recommendations will be followed by data pipelines developed under the SOLARNET project as well as e.g. the Solar Orbiter SPICE pipeline and the SST CHROMIS/CRISP common pipeline. These recommendations are meant to function as a common reference to which even existing diverse data sets may be related, for ingestion into solar virtual observatories and for analysis by generic software.

description: We review and analyze the hybrid quantum-classical NMR computing methodology referred to as Type-II quantum computing. We show that all such algorithms considered so far within this paradigm are equivalent to some classical lattice-Boltzmann scheme. We derive a sufficient and necessary constraint on the unitary operator representing the quantum mechanical part of the computation which ensures that the model reproduces the Boltzmann approximation of a lattice-gas model satisfying semi-detailed balance. Models which do not satisfy this constraint represent new lattice-Boltzmann schemes which cannot be formulated as the average over some underlying lattice gas. We close the paper with some discussion of the strengths, weaknesses and possible future direction of Type-II quantum computing.

description: In a recent paper published in this Journal, Khordad and collaborators [J Low Temp Phys (2018) 190:200] have studied the thermodynamics properties of a GaAs double ring-shaped quantum dot under external magnetic and electric fields. In that meritorious research the energy of system was obtained by solving the Schrödinger equation. The radial equation was mapped into a confluent hypergeometric differential equation and the differential equation associated to $z$ coordinate was mapped into a biconfluent Heun differential equation. In this paper, it is pointed out a misleading treatment on the solution of the biconfluent Heun equation. It is shown that the energy $E_{z}$ can not be labeled with $n_{z}$ and this fact jeopardizes the results of this system. We calculate the partition function with the correct energy spectrum and recalculate the specific heat and entropy as a function of low and high temperatures.

description: A pilot testing of a Gravitational Water Vortex Hydropower Plant (GWVHP) has been done to evaluate the applicability in a real-world scenario and validate the results from the lab-scale model. A scaled-up model of a capacity of 1 kW was constructed for the evaluation purpose. The test provided data in good agreement with a lab-scale model and a proper visualization to install Gravitational Water Vortex in real-world scenarios. The project lasted for nearly four months and thus provided important information on the problems that might arise in scaling up the lab model to a micro-hydro system. The pilot testing shows an overall plant efficiency of 49%, validating the lab-based studies conducted beforehand. The information obtained from this pilot study shall be implemented in a micro-hydro project on a larger scale.

description: We study the path-integral formalism in the imaginary-time to show its validity in a case with a metastable ground state. The well-known method based on the bounce solution leads to the imaginary part of the energy even for a state that is only metastable and has a simple oscillating behavior instead of decaying. Although this has been argued to be the failure of the Euclidean formalism, we show that proper account of the global structure of the path-space leads to a valid expression for the energy spectrum, without the imaginary part. For this purpose we use the proper valley method to find a new type of instanton-like configuration, the ``valley instantons''. Although valley instantons are not the solutions of equation of motion, they have dominant contribution to the functional integration. A dilute-gas approximation for the valley instantons is shown to lead to the energy formula. This method extends the well-known imaginary-time formalism so that it can take into account the global behavior of the theory.

A recurrence relation for elliptic divisibility sequences
Creators: name: Verzobio, Matteo
Publisher: name: arXiv
Year: 2021
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: In literature, there are two different definitions of elliptic divisibility sequences. The first one says that a sequence of integers $\{h_n\}_{n\geq 0}$ is an elliptic divisibility sequence if it verifies the recurrence relation $h_{m+n}h_{m-n}h_{r}^2=h_{m+r}h_{m-r}h_{n}^2-h_{n+r}h_{n-r}h_{m}^2$ for every natural number $m\geq n\geq r$. The second definition says that a sequence of integers $\{β_n\}_{n\geq 0}$ is an elliptic divisibility sequence if it is the sequence of the square roots (chosen with an appropriate sign) of the denominators of the abscissas of the iterates of a point on a rational elliptic curve. It is well-known that the two sequences are not equivalent. Hence, given a sequence of the denominators $\{β_n\}_{n\geq 0}$, in general does not hold $β_{m+n}β_{m-n}β_{r}^2=β_{m+r}β_{m-r}β_{n}^2-β_{n+r}β_{n-r}β_{m}^2$ for $m\geq n\geq r$. We will prove that the recurrence relation above holds for $\{β_n\}_{n\geq 0}$ under some conditions on the indexes $m$, $n$, and $r$.

The data sample consists of nearly 14,000 Z/G* -> e+e- candidates corresponding to the integrated luminosity of 0.4 fb-1 collected using the D0 detector. Ratios of the Z/G* + >= n jet cross sections to the total inclusive Z/G* cross section have been measured for n = 1 to 4 jet events. Our measurements are found to be in good agreement with a next-to-leading order QCD calculation and with a tree-level QCD prediction with parton shower simulation and hadronization.

description: Satellites are the efficient way to achieve global scale quantum communication (Q.Com) because unavoidable losses restrict fiber based Q.Com to a few hundred kilometers. We demonstrate the feasibility of establishing a Q.Com uplink with a tiny 3U CubeSat (measuring just 10X10X32 cm^3 ) using commercial off-the-shelf components, the majority of which have space heritage. We demonstrate how to leverage the latest advancements in nano-satellite body-pointing to show that our 4kg CubeSat can provide performance comparable to much larger 600kg satellite missions. A comprehensive link budget and simulation was performed to calculate the secure key rates. We discuss design choices and trade-offs to maximize the key rate while minimizing the cost and development needed. Our detailed design and feasibility study can be readily used as a template for global scale Q.Com.

description: This thesis focuses on the design, modeling, fabrication, and testing of a ?ying and walking robot, called the Dynamic Underactuated Flying-Walking (DUCK) robot. The DUCK robot combines a high-mobility ?ying platform, such as a quadcopter (quadrotor helicopter), with passive-dynamic legs to create a versatile system that can ?y and walk. One of the advantages of using passive-dynamic legs for walking is that additional actuators are not needed for terrestrial locomotion, therefore simplifying the design, reducing overall weight, and decreasing power consumption. First, a mathematical model is developed for the DUCK robot, where the modeling combines the passive-dynamic walking mechanism with the swinging mass of the aerial platform. Second, simulations based on the model are used to help guide the design of two prototype robots, speci?cally to tailor the shape of the feet and the dimensions of the passive-dynamic walking mechanism. Third, an energy analysis is performed to compare the performances between ?ying and walking. More specifically, simulation results show that continuous active walking has a comparable energy efficiency to that of flying for the two prototype designs. For design Version 1, it is estimated that the robot is able to walk up to 1600 meters on a 30kJ battery (standard Li-Po battery) with a cost of transport of 1.0, while the robot can potentially fly up to 1800 meters horizontally with the weight of its legs and up to 2300 meters without the weight of its legs. Design Version 2 is estimated to be able to walk up to 4600 meters on a 30kJ battery with a cost of transport of .50, while it could fly up to 2600 meters with the weight of its legs or 4300 meters without its legs. The cost of transport of flying is estimated to be .89 in all scenarios. Finally, experimental results demonstrate the feasibility of combining an aerial platform with passive-dynamic legs to create an effective flying and walking robot. Two modes of walking are experimentally demonstrated: (1) passive walking down inclined surfaces for low-energy terrestrial locomotion and (2) active (powered) walking leveraging the capabilities of the flying platform, where thrust from the quadcopter's rotors enables the DUCK robot to walk on flat surfaces or up inclined surfaces.

The cyanobactin biosynthetic machinery: Promiscuity, modularity and unique chemistry from the oceans
Creators: name: Sardar, Debosmita
Publisher: name: University of Utah
Year: 2019
Subjects: Biochemistry

description: Cyanobactins are peptide natural products that fall under the broad class of the ribosomally synthesized and posttranslationally modified peptides (RiPPs). Since they are synthesized by the ribosome, the biosynthesis of these peptides is genetically encoded. A precursor peptide gene carries the primary amino acid sequence of the natural product. The precursor peptide is surrounded by other genes, which encode posttranslational enzymes that decorate the primary sequence with elaborate structural motifs. Due to the genetically encoded origins of the cyanobactins, simple manipulations at the peptide sequence level are tolerable and lead to the creation of a diversity of natural products. The roots to this tolerance lie in the innate extreme broad-substrate nature of the posttranslational enzymes. Here, we explore the biochemical basis of this promiscuity and in vitro methodologies to create structurally elaborate peptidic motifs. In addition, the cyanobactin biosynthetic machinery is a rich source of enzymes capable of performing a wide array of intriguing chemistry and here we probe into some of these mechanisms. Put together, the broad-substrate nature coupled with the unique enzymology of the cyanobactin biosynthetic machinery provides a toolkit for the creation of designer peptide motifs. This work holds promise in the field of peptide-based drug discovery.

Studying this equation in the context of optical hyper-parametric oscillators in anomalous-dispersion dissipative cavities, where NLSE is usually referred to as the Lugiato-Lefever equation (LLE), we are led to a new, reduced nonlinear oscillator model which uncovers the essence of the spontaneous creation of sharply peaked pulses in optical resonators. We identify attracting solutions for this model which correspond to stable cavity solitons and Turing patterns, and study their degree of stability. The reduced model embodies the fundamental connection between mode synchronization and spatiotemporal pattern formation, and represents a novel class of self-synchronization processes in which coupling between nonlinear oscillators is governed by energy and momentum conservation.

description: Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease that is almost uniformly lethal within the first year of diagnosis and is the fourth leading cause of cancer deaths in the United States. Activating mutations in the KRAS protooncogene are found in nearly all human PDAC cases as well as in early putative PDAC precursor lesions, pancreatic intraepithelial neoplasias (PanINs). Modeling of PDAC has been achieved through expression of an activated Kras allele in mouse pancreas that results in PanINs similar to those found in humans. PanINs develop focally, however, despite ubiquitous expression of mutant Kras suggesting that other factors must be involved in Kras-induced PanIN formation. Due to ubiquitous expression of mutant Kras in the pancreas, it is unknown which cell type, or types, can contribute to PanINs. This thesis aims to understand the cellular events that lead to Kras-induced PanIN formation, and to identify the cellular origin of PDAC. We find that mature acinar cells of the adult pancreas are competent to form PanIN lesions following Kras activation, and this process is dramatically accelerated by co-activation of the Notch signaling pathway, which antagonizes differentiation during pancreas development, but is largely inactive in the adult. Lineage tracing indicates that Kras/Notch co-activation drives rapid acinar-to-ductal metaplasia (ADM) during which acinar cells take on a duct-like phenotype, providing a mechanism by which acinar cells can serve as the origin of a "ductal" tumor. During ADM, acinar cells lose expression of Ptf1a, a transcription factor that is considered the master regulator of acinar cell identity. To test the requirement for Notch in PanIN initiation we deleted the key Notch mediator RbpJ. Surprisingly, we found that loss of RbpJ resulted in an increase in Kras-induced PanIN formation. In the pancreas, however, RbpJ is part of the Ptf1a complex and we suspect that loss of RbpJ could alter Ptf1a complex function and perturb acinar cell differentiation, which could allow for Kras to drive PanIN formation. We formally tested whether loss of Ptf1a would allow for increased Kras-driven PanIN formation and found that, in the presence of activated Kras, Ptf1a null acinar cells rapidly formed PanINs. Expression loss of key differentiation factors resulting in ADM may in fact be the initial step towards Kras induced tumorigenesis. ADM is similarly seen during acute pancreatitis, although, ultimately, acinar differentiation is restored during the regeneration process. We find that inducing pancreatitis in animals harboring active Kras mutations results in rapid and robust PanIN initiation

description: The extreme ultraviolet plasma emission from liquid microsized argon droplets exposed to intense near-infrared laser pulses has been investigated. Emission from the warm dense matter targets is recorded in a spectral range in between 16 and 30 nm at laser intensities of 10^14 W/cm^2. Above the emission threshold, soft x-ray radiation exponentially increases with the pulse energy whereby a strong dependence of the yields on the pulse duration is observed, which points at an effective electron collisional heating of the microplasma by inverse bremsstrahlung. Accompanying hydrodynamic simulations reveal the temporal and spatial development of the microplasma conditions. The good agreement in between the measured and calculated emission spectra as well as the extracted electron temperatures confirm that hydrodynamic simulations can be applied in the analysis of strongly excited droplets.

Debugging with Domain-specific Events via Macros

description: Domain-specific languages (DSLs) are increasingly popular, and there are a variety of ways to create a DSL. A DSL designer might write an interpreter from scratch, compile the DSL to another language, express DSL concepts using only the existing forms of an existing language, or implement DSL constructs using a language's extension capabilities, including macros. While extensible languages can offer the easiest opportunity for creating a DSL that takes advantage of the language's existing infrastructure, existing tools for debugging fail to adequately adapt the debugging experience to a given domain. This dissertation addresses the problem of debugging DSLs defined with macros and describes an event-oriented approach that works well with a macro-expansion view of language implementation. It pairs the mapping of DSL terms to host terms with an event mapping to convert primitive events back to domain-specific concepts. Domain-specific events can be further inspected or manipulated to construct domain-specific debuggers. This dissertation presents a core model of evaluation and events and also presents a language design-analogous to pattern-based notations for macros, but in the other direction-for describing how events in a DSL's expansion are mapped to events at the DSL's level. The domain-specific events can enable useful, domain-specific debuggers, and the dissertation introduces a design for a debugging framework to help with debugger construction. To validate the design of the debugging framework, a debugging framework, Ripple, is implemented, and this dissertation demonstrates that with a modest amount of work, Ripple can support building domain-specific debuggers.

description: Starting with nearby galaxy clusters like Virgo and Coma, and continuing out to the furthest galaxy clusters for which ISO results have yet been published ($z=0.56$), we discuss the development of knowledge of the infrared and associated physical properties of galaxy clusters from early IRAS observations, through the "ISO-era" to the present, in order to explore the status of ISO's contribution to this field. Relevant IRAS and ISO programmes are reviewed, addressing both the cluster galaxies and the still-very-limited evidence for an infrared-emitting intra-cluster medium. ISO made important advances in knowledge of both nearby and distant galaxy clusters, such as the discovery of a major cold dust component in Virgo and Coma cluster galaxies, the elaboration of the correlation between dust emission and Hubble-type, and the detection of numerous Luminous Infrared Galaxies (LIRGs) in several distant clusters. These and consequent achievements are underlined and described. We recall that, due to observing time constraints, ISO's coverage of higher-redshift galaxy clusters to the depths required to detect and study statistically significant samples of cluster galaxies over a range of morphological types could not be comprehensive and systematic, and such systematic coverage of distant clusters will be an important achievement of the Spitzer Observatory.

description: This thesis discusses the design, modeling, and experimental validation of an inductively coupled wireless power transfer (WPT) system to power a micro aerial vehicle (MAV) without an onboard power source. MAVs are limited in utility by flight times ranging from 5 to 30 minutes. Using WPT for MAVs, in general, extends flight time and can eliminate the need for batteries. In this paper, a resonant inductive power transfer system (RIPT), consisting of a transmit (Tx) coil on a fixed surface and a receive (Rx) coil attached to the MAV, is presented, and a circuit is described. The RIPT system design is modeled to determine a suitable geometry for the coils, and the model validated experimentally. It is found that for the MAV used in this work, a suitable geometry of coils is a 19cm diameter planar spiral Tx coil made with 14 AWG copper wire, seven turns, and 5cm pitch paired with an Rx coil made of 16-20AWG wire, 13cm-20cm diameter, 1mm pitch, and one to two turns. A demonstration of an MAV being powered 11cm above the Tx coil with the WPT system in a laboratory setting is presented. The MAV consumes approximately 12 Watts. The overall power efficiency of the RIPT system from RF power source output to MAV motors is approximately 32%.

description: Recommender models are commonly used to suggest relevant items to a user for e-commerce and online advertisement-based applications. These models use massive embedding tables to store numerical representation of items' and users' categorical variables (memory intensive) and employ neural networks (compute intensive) to generate final recommendations. Training these large-scale recommendation models is evolving to require increasing data and compute resources. The highly parallel neural networks portion of these models can benefit from GPU acceleration however, large embedding tables often cannot fit in the limited-capacity GPU device memory. Hence, this paper deep dives into the semantics of training data and obtains insights about the feature access, transfer, and usage patterns of these models. We observe that, due to the popularity of certain inputs, the accesses to the embeddings are highly skewed with a few embedding entries being accessed up to 10000x more. This paper leverages this asymmetrical access pattern to offer a framework, called FAE, and proposes a hot-embedding aware data layout for training recommender models. This layout utilizes the scarce GPU memory for storing the highly accessed embeddings, thus reduces the data transfers from CPU to GPU. At the same time, FAE engages the GPU to accelerate the executions of these hot embedding entries. Experiments on production-scale recommendation models with real datasets show that FAE reduces the overall training time by 2.3x and 1.52x in comparison to XDL CPU-only and XDL CPU-GPU execution while maintaining baseline accuracy

description: We investigate the Rényi entropy of independent sums of integer valued random variables through Fourier theoretic means, and give sharp comparisons between the variance and the Rényi entropy, for Poisson-Bernoulli variables. As applications we prove that a discrete ``min-entropy power'' is super additive on independent variables up to a universal constant, and give new bounds on an entropic generalization of the Littlewood-Offord problem that are sharp in the ``Poisson regime''.
Measurement of azimuthal asymmetries in neutral current deep inelastic scattering at HERA

description: The distribution of the azimuthal angle of charged and neutral hadrons relative to the lepton plane has been studied for neutral current deep inelastic $ep$ scattering using an integrated luminosity of 45 pb-1 taken with the ZEUS detector at HERA. The measurements were made in the hadronic centre-of-mass system. The analysis exploits the energy-flow method, which allows the measurement to be made over a larger range of pseudorapidity compared to previous results. The dependence of the moments of the azimuthal distributions on the pseudorapidity and minimum transverse energy of the final-state hadrons are presented. Although the predictions from next-to-leading-order QCD describe the data better than do the Monte Carlo models incorporating leading-logarithm parton showers, they still fail to describe the magnitude of the asymmetries. This suggests that higher-order calculations may be necessary to describe these data.
