description: Starting from a consistent SU(6) extension of the Weinberg-Tomozawa (WT) meson-baryon chiral Lagrangian (Phys. Rev. D74 (2006) 034025), we study the s-wave meson-baryon resonances in the strangeness S=-3 and negative parity sector. Those resonances are generated by solving the Bethe-Salpeter equation with the WT interaction used as kernel. The considered mesons are those of the 35-SU(6)-plet, which includes the pseudoscalar (PS) octet of pions and the vector (V) nonet of the rho meson. For baryons we consider the 56-SU(6)-plet, made of the 1/2+ octet of the nucleon and the 3/2+ decuplet of the Delta. Quantum numbers I(J^P)=0(3/2^-) are suggested for the experimental resonances Omega*(2250)- and Omega*(2380)-. Among other, resonances with I=1 are found, with minimal quark content sss\bar{l}l', being s the strange quark and l, l' any of the the light up or down quarks. A clear signal for such a pentaquark would be a baryonic resonance with strangeness -3 and electric charge of -2 or 0, in proton charge units. We suggest looking for K- Xi- resonances with masses around 2100 and 2240 MeV in the sector 1(1/2^-), and for pi Omega- and K- Xi*- resonances with masses around 2260 MeV in the sector 1(3/2^-).

description: The Odin satellite, launched in Feb. 2001, is equipped with a 1.1-m submillimetre telescope. Odin was used to observe the 557 GHz line of water with high spectral resolution in 12 comets between 2001 and 2005. Line shapes and spatial mapping provide information on the anisotropy of the outgassing and constraints on water excitation, enabling accurate measurements of the water production rate. Five comets were regularly observed over periods of more than one month to monitor the variation of their water outgassing rate with heliocentric distance. Observing campaigns have been generally coordinated with ground-based observations of molecular lines at Nançay, CSO or IRAM 30-m telescopes to obtain molecular abundances relative to water. Thanks to Odin's frequency coverage, it was also possible to detect the H_2^18O 548GHz line, first in comet 153P/Ikeya-Zhang in April 2002 (Lecacheux et al., 2003) and then in comets C/2002 T7 (LINEAR), C/2001 Q4 (NEAT) and C/2004 Q2 (Machholz). The ^16O/^18O isotopic ratio (\approx450) is consistent with the terrestrial value. Ammonia has been searched for in three comets through its J_K = 1_0-0_0 line at 572 GHz and was tentatively detected in C/2001 Q4 and C/2002 T7. The derived abundances of NH_3 relative to water are 0.5 % and 0.3 %, respectively, similar to values obtained in other comets with different techniques.

Asymmetrical mass ejection from proto-white dwarfs and the formation of eccentric millisecond pulsar binaries

description: Binary millisecond pulsars (MSPs) are believed to have descended from low-mass X-ray binaries (LMXBs), which have experienced substantial mass transfer and tidal circularization. Therefore, they should have very circular orbits. However, the discovery of several eccentric binary MSPs (with eccentricity $e\sim 0.01-0.1$) challenges this standard picture. Three models have been proposed thus far based on accretion-induced collapse of massive white dwarfs (WDs), neutron star-strange star transition, and formation of circumbinary disks. All of them are subject to various uncertainties, and are not entirely consistent with observations. Here we propose an alternative model taking into account the influence of thermonuclear flashes on proto-WDs. We assume that the flashes lead to asymmetrical mass ejection, which imparts a mild kick on the proto-WDs. By simulating orbital changes of binary MSPs with multiple shell flashes, we show that it is possible to reproduce the observed eccentricities, provided that the kick velocities are around a few kms$^{-1}$.

description: We have built an effective Walecka-type hadronic Lagrangian in which the hadron masses and the density dependence of the coupling constants are deduced from the quark dynamics using a Nambu-Jona-Lasinio model. The parameters of this Nambu-Jona-Lasinio model have been determined using the meson properties in the vacuum but also in the medium through the omega meson mass in nuclei measured by the TAPS collaboration. Realistic properties of nuclear matter have been obtained.

description: It is widely believed that topological superconductivity, a hitherto elusive phase of quantum matter, can be achieved by inducing superconductivity in topological materials. In search of such topological superconductors, certain topological insulators (like, Bi$_2$Se$_3$) were successfully turned into superconductors by metal-ion (Cu, Pd, Sr, Nb etc. ) intercalation. Superconductivity could be induced in topological materials through applying pressure as well. for example, a pressure-induced superconducting phase was found in the topological insulator Bi$_2$Se$_3$. However, in all such cases, no conclusive signature of topological superconductivity was found. In this review, we will discuss about another novel way of inducing superconductivity in a non-superconducting topological material -- by creating a mesoscopic interface on the material with a non-superconducting, normal metallic tip where the mesoscopic interface becomes superconducting. Such a phase is now known as a tip-induced superconducting (TISC) phase. This was first seen in 2014 on Cd$_3$As$_2$ at IISER Mohali, India. Following that, a large number of other topological materials were shown to display TISC. Since the TISC phase emerges only at a confined region under a mesoscopic point contact, traditional bulk tools for characterizing superconductivity cannot be employed to detect/confirm such a phase. On the other hand, such a point contact geometry is ideal for probing the possible existence of a temperature and magnetic field dependent superconducting energy gap and a temperature and magnetic field dependent critical current. We will review the details of the experimental signatures that can be used to prove the existence of superconductivity even when the "text-book" tests for detecting superconductivity cannot be performed. Then, we will review different systems where a TISC phase could be realized.

description: Birch pollen allergic patients show cross-reactivity to vegetables and fruits, including strawberries (Fragaria × ananassa). The objective of this study was to quantify the level of the Fra a 1 protein, a Bet v 1-homologous protein in strawberry fruits by a newly developed ELISA, and determine the effect of genotype, cultivation and food processing on the allergen amount. An indirect competitive ELISA using a specific polyclonal anti-Fra a 1.02 antibody was established and revealed high variability in Fra a 1 levels within 20 different genotypes ranging from 0.67 to 3.97 µg/g fresh weight. Mature fruits of red-, white- and yellow-fruited strawberry cultivars showed similar Fra a 1 concentrations. Compared to fresh strawberries, oven and solar-dried fruits contained slightly lower levels due to thermal treatment during processing. SDS-PAGE and Western blot analysis demonstrated degradation of recombinant Fra a 1.02 after prolonged (>10 min) thermal treatment at 99 °C. In conclusion, the genotype strongly determined the Fra a 1 quantity in strawberries and the color of the mature fruits does not relate to the amount of the PR10-protein. Cultivation conditions (organic and conventional farming) do not affect the Fra a 1 level, and seasonal effects were minor.

description: We present recent results from several on-going studies: The first addresses the question of gas-density thresholds for star formation, as probed by the outer disks of normal nearby galaxies. The second concerns the observational evidence for the existence of gravitating non-luminous (GNL) galaxies, as predicted by most recent simulations of galaxy formation in Lambda-CDM cosmologies. We find that (1) If star formation is traced by far-ultraviolet light, then there is no evidence for a threshold to star formation at any gas density so far probed, and (2) there is no evidence for GNL galaxies gravitationally interacting with known optical systems based on the observations (a) that there are no ring galaxies without plausible optically visible intruders, (b) all peculiar galaxies in the Arp Atlas that are bodily distorted have nearby plausibly interacting companions, and (c) there are no convincingly distorted/peculiar galaxies within Karachentsev's sample of more than 1,000 apparently/optically isolated galaxies.

description: In an effort to obtain further observational evidences for secular evolution processes in galaxies, as well as observational constraints to current theoretical models of secular evolution, we have used BVRI and Ks images of a sample of 18 barred galaxies to measure the lengths and colours of bars, create colour maps and estimate global colour gradients. In addition, applying a method we developed in a previous article, we could distinguish for 7 galaxies in our sample those whose bars have been recently formed from the ones with already evolved bars. We estimated an average difference in the optical colours between young and evolved bars that may be translated to an age difference of the order of 10 Gyr, meaning that bars may be long standing structures. Moreover, our results show that, on average, evolved bars are longer than young bars. This seems to indicate that, during its evolution, a bar grows longer by capturing stars from the disk, in agreement with recent numerical and analytical results.

description: I investigate the discrepancy between the evolution and pulsation masses for Cepheid variables. A number of recent works have proposed that non-canonical mass-loss can account for the mass discrepancy. This mass-loss would be such that a 5Mo star loses approximately 20% of its mass by arriving at the Cepheid instability strip; a 14Mo star, none. Such findings would pose a serious challenge to our understanding of mass-loss. I revisit these results in light of the Padova stellar evolutionary models and find evolutionary masses are ($17\pm5$)% greater than pulsation masses for Cepheids between 5

Modelling and identification of paper machine wet end chemistry
Creators: name: Shirt, Roger William
Publisher: name: University of British Columbia
Year: 2009

description: Chemicals are added in the wet end of a paper machine to control operability and/or quality measures such as retention, drainage, sheet strength, etc. Current understanding of the effects of such additives in a mill environment is generally restricted to either qualitative or empirical descriptions. This is primarily due to the large number of interacting factors present in the aqueous papermaking environment as well as variations in furnish properties. Furthermore, the existence of large time constants and recycle flows in the white water system leads to complex mixing dynamics. This inability to quantitatively predict process performance inhibits development of closed-loop control schemes. This thesis is an attempt to bridge the gap between development of fundamental papermaking chemistry models in the laboratory and application of these models in a mill environment.. A dynamic simulation approach is used to model the interactions between chemical additives and furnish particles. Detailed descriptions of the polymer adsorption, flocculation and wire retention and drainage processes are developed. Consistencies of all furnish particles, in particular fines, are faithfully tracked throughout the wet end. The effects of operating variables such as polymer addition rates, furnish composition, degree of stock refining and applied vacuum can be directly assessed in a simulated operating environment. Results are compared against on-line data from a fine paper mill in Canada are shown to be accurate. Identification tools are also developed as part of the overall goal of identifying a model suitable for controller design. A method is first proposed for specifying a confidence interval on the anticipated controller robustness at the identification stage. This is accomplished through optimization of a controller robustness measure with the constraint that the model parameters lie within a (l-⍺)% confidence interval. Parametric nonlinearity is accounted for by this method and the efficacy of the method is shown to be, in part, a function of the degree of this nonlinearity. Input test signals can be chosen which minimize this uncertainty and a method is developed for this purpose. Identification techniques are applied to the High Molecular Weight Anionic Polymer Flowrate White Water Filler Consistency loop. Significant nonlinear behaviour is found to exist in the higher order dynamics of this pairing. While the control relevant identification techniques developed in this thesis are not effective due to the nonlinearities present the value of an accurate dynamic simulation is highlighted.

description: Tackling unsupervised source separation jointly with an additional inverse problem such as deconvolution is central for the analysis of multi-wavelength data. This becomes highly challenging when applied to large data sampled on the sphere such as those provided by wide-field observations in astrophysics, whose analysis requires the design of dedicated robust and yet effective algorithms. We therefore investigate a new joint deconvolution/sparse blind source separation method dedicated for data sampled on the sphere, coined SDecGMCA. It is based on a projected alternate least-squares minimization scheme, whose accuracy is proved to strongly rely on some regularization scheme in the present joint deconvolution/blind source separation setting. To this end, a regularization strategy is introduced that allows designing a new robust and effective algorithm, which is key to analyze large spherical data. Numerical experiments are carried out on toy examples and realistic astronomical data.

description: The radio supernova remnant W50 hosts at its center the peculiar galactic X-ray binary SS 433. It shows a central spherical structure with two `ears' which are supposed to be formed by the interaction of the precessing jets of SS 433 with the supernova shell. In two pointings in September/October 2004 for 30 ks each the eastern jet of SS 433 was observed with XMM-Newton to study the outermost parts of the `ear' and the X-ray bright emission region about 35 arcmin from SS 433. The spectra consist of two components: a non-thermal power law with photon index Γ~ 2.17+/-0.02 and a thermal component at a typical temperature of kT ~ 0.3 keV. The X-ray emission seems to fill the whole interior region of the radio remnant W50. The jet terminates in the eastern `ear' in a ring-like terminal shock which indicates a flow with a kind of hollow-cone morphology. The spatial coincidence of X-ray and radio emission suggests physical conditions similar to those found at the outer shocks of ordinary supernova remnants. The bright emission region closer to SS 433 radiates non-thermally in a spatially well confined geometry at higher X-ray energies. At soft X-rays the shape of the region gets blurred, centered on the hard lenticular emission. The shape of this region and the bend in the jet propagation direction might be caused by the interaction of a re-collimated jet with the outer, non homogeneous interstellar matter distribution. The physical conditions leading to the re-collimation of the jet and the peculiar emission morphology are far from being understood and require deeper observations as well as a detailed modeling of the interaction of a jet with its surroundings.

description: When statistical inversion of a lag profile is used to determine an incoherent scatter target, the posterior variance of the estimated target can be used to determine how well a certain set of transmission codes perform. In this work we present an incoherent scatter radar transmission code optimization search method suitable for different modulation types, including binary phase, polyphase and amplitude modulation. We find that the combination of amplitude and phase modulation provides better performance than traditional binary phase coding, in some cases giving better accuracy than alternating codes.

description: The article is based on the results of research work on the study of the activities, constitutional and legal status as well as self-employed citizens. The purpose of the study is to analyze the essence of selfemployment as a socio-economic phenomenon, the extent of its prevalence, the analysis of measures taken by the state to legalize the self-employed and create favorable conditions for their activities, as well as proposals for the development of current legislation. The analysis shows that self-employment is a special type of business activity, but it is difficult to be regulated by the state due to its predominantly «shadow» nature. The article further discusses how to improve the mechanism for legalizing the activities of the self-employed, taking into account the opinions and assessments of citizens working on the basis of self-employment

The state, its bodies, officials, public associations, citizens act in accordance with the Constitution and laws. The Constitution of the Republic of Uzbekistan plays an important role in improving the organization of work with citizens’ appeals in government bodies. Our Fundamental Law allows the implementation of democratic reforms in the country, the creation of effective mechanisms to ensure the rights and freedoms of citizens, the level of satisfaction with the activities of the executive branch of the world trends in public administration. A citizen’s appeal is a written proposal, statement or complaint addressed to state authorities, local authorities or officials, as well as an oral appeal of a citizen to a state authority, local government body. Citizens’ appeals are one of the important tools for the implementation and protection of individual rights, strengthening the relationship between the state apparatus and the population. The appeals help to strengthen the control of the population over the activities of state authorities and local selfgovernment. The right to appeal shows that citizens’ influence on government decisions is not limited to the right to electgovernment bodies.

description: Deep learning-based super-resolution (SR) techniques have generally achieved excellent performance in the computer vision field. Recently, it has been proven that three-dimensional (3D) SR for medical volumetric data delivers better visual results than conventional two-dimensional (2D) processing. However, deepening and widening 3D networks increases training difficulty significantly due to the large number of parameters and small number of training samples. Thus, we propose a 3D convolutional neural network (CNN) for SR of medical volumetric data called ParallelNet using parallel connections. We construct a parallel connection structure based on the group convolution and feature aggregation to build a 3D CNN that is as wide as possible with few parameters. As a result, the model thoroughly learns more feature maps with larger receptive fields. In addition, to further improve accuracy, we present an efficient version of ParallelNet (called VolumeNet), which reduces the number of parameters and deepens ParallelNet using a proposed lightweight building block module called the Queue module. Unlike most lightweight CNNs based on depthwise convolutions, the Queue module is primarily constructed using separable 2D cross-channel convolutions. As a result, the number of network parameters and computational complexity can be reduced significantly while maintaining accuracy due to full channel fusion. Experimental results demonstrate that the proposed VolumeNet significantly reduces the number of model parameters and achieves high precision results compared to state-of-the-art methods.

description: We study the evolution of axions interacting with primordial magnetic fields (PMFs) starting just from the QCD phase transition in the expanding universe. This interaction is owing to the Primakoff effect. Adopting the zero mode approximation for axions, we derive the system of equations for axions and magnetic fields, where the expansion of the universe and the spectra of magnetic fields are accounted for exactly. We find that the contribution of the Primakoff effect to the dynamics of axions and magnetic fields is rather weak. It confirms some previous estimates leading to analogous conclusions, when accounting here for the Hubble expansion both for an uniform axion field and non-uniform PMFs using Fourier spectra for their energy and helicity densities. We solve the corresponding system of the evolution equations and find that the axion zero mode, when evolving during radiation era, has its amplitude at the level sufficient for that axion to be a good candidate for the cold dark matter.

description: We present new observations of the white dwarf sequence of the old open cluster NGC 6791. The brighter peak previously observed in the white dwarf luminosity function (WDLF) is now better delineated, and the second, fainter peak that we suggested earlier is now confirmed. A careful study suggests that we have reached the end of the white dwarf sequence. The WDs that create the two peaks in the WDLF show a significant turn to the blue in the color-magnitude diagram. The discrepancy between the age from the WDs and that from the main sequence turnoff remains, and we have an additional puzzle in the second peak in the WDLF. Canonical WD models seem to fail --at least at ~25%-level-- in reproducing the age of clusters of this metallicity. We discuss briefly possible ways of arriving at a theoretical understanding of the WDLF.

No evidence was found for the recently reported 0$_2^{+}$ 639-keV level suggested as evidence for low-energy shape coexistence in $^{80}$Ge. Large-scale shell model calculations performed in $^{78,80,82}$Ge place the $0^{+}_{2}$ level in $^{80}$Ge at 2\,MeV. The new experimental evidence combined with shell model predictions indicate that low-energy shape coexistence is not present in $^{80}$Ge.

description: Everyone knows that the market economy is being improved through fair and healthy competition. However, today’s economy displays various types of unfair competition, which has a negative impact on market relations. In practice, quite often, there is such a form of unfair competition as to discredit in relation to competitors. It should be noted that the current legislation of the Republic of Uzbekistan provides a very general definition of the concept of unfair competition, while the current practice requires a clear and precise explanation of the methods described in this definition. In other words, the mechanism and nature of actions discreditation, which can cause damage or loss of business reputation are not specified. This article provides an expanded definition of «discrediting» as a prohibited form of unfair competition under the Law of the Republic of Uzbekistan «On Competition», based on international norms and legislative bases of foreign countries. The article, based on an analysis of the legislation of the Republic of Uzbekistan, the legal norms of foreign countries and scientific literature, reveals the peculiarities of damage to business reputation by disseminating false, inaccurate and distorted information about a competitor.

description: As defined in the SSHOC workplan, task 2.3 SSHOC web presence will cover all activities related to the design, development, roll-out and continuous update of the SSHOC web presence. An evolved SSHOC web platform will ensure a service-oriented approach to the SSHOC marketplace developed in WP7 and will act as the main project entry point providing a multi-view of the SSH landscape, according to the main research lines of the ERICs involved, namely Art and Humanities, Social Science, Linguistics. The SSHOC web platform will be conceived and structured to ensure visibility and easy access to the technologies and services resulting from WP3, as well as innovations mechanisms in data production (WP4), use cases (WP5) and training materials (WP6), targeting data producers and data re-users in the SSH disciplines, as well as industry players. The web platform will also serve as main repository for all published content and allow access to project deliverables and external resources. It will have specific sections dedicated to events and workshops; it may contain sections to collect user feedbacks and online surveys. It will be able to optionally host any software repository developed within SSHOC and will provide direct access points to the ERICs websites and other relevant websites, existing catalogues and virtual labs. This task will also provide branding for the Marketplace (WP7) and support to improve its Graphical User Interface (GUI) and end-user friendliness. Specific branding of the new services will also be provided, making their look & feel homogeneous under the SSHOC umbrella. In M15, March 2020, the third iteration of the SSHOC web platform was achieved (Milestone 5), this document will outline the milestone, its role and the means of verification to its achievement.

description: The following dataset consists of the seismic waveforms created for studying impact crater clusters on Mars.
description: We investigated the seismic signatures of recent impact crater clusters on Mars that would be recorded by the InSight Seismic Experiment for Interior Structure (SEIS) seismometers. We used a database of 77 measured and dated impact sites, with craters with effective diameters between 2.1 and 33.8 m, along with inferred impact angle, bolide trajectory, and varying target material properties to empirically scale for the momentum, expected seismic source function, and radiation pattern of impacts. The impact source is simulated in a local 3-D finite difference wave propagation code and coupled to teleseismic distances by scaling the spectra of 1-D global synthetic seismograms. We use the SEIS noise floors to estimate seismic detectability of impact(s) across azimuth and distance. Our experiments reveal that impact clusters have a higher peak corner frequency resulting from energy contributed by smaller craters to the power spectrum. We also find that the time separation between individual impacts in a cluster is small (< 10-15 milliseconds) and a require a seismometer closely situated to the source (< 10 km) and a high sampling rate (> 100 Hz) to resolve individual impacts within the cluster. Two of the clusters in our database (> 20 m effective diameter) would have been detectable by InSight, with the assumptions that the martian background noise and background attenuation are both low. Joint detection of surface changes from newly formed crater(s) in images and by SEIS will provide precise source locations that are crucial for constraining the internal structure of Mars.

description: Context. The star formation rates and stellar densities found in young massive clusters suggest that these stellar systems originate from gas at densities n(H$_2$) $>10^7$ cm$^{-3}$. Until today, however, the physical characterization of this ultra high density material remains largely unconstrained in observations. Aims. We investigated the density properties of the star-forming gas in the OMC-1 region located in the vicinity of the Orion Nebula Cluster (ONC). Methods. We mapped the molecular emission at 652 GHz in OMC-1 as part of the APEX-SEPIA660 Early Science. Results. We detect bright and extended N$_2$H$^+$ (J=7-6) line emission along the entire OMC-1 region. Comparisons with previous ALMA data of the (J=1-0) transition and radiative transfer models indicate that the line intensities observed in this N$_2$H$^+$ (7-6) line are produced by large mass reservoirs of gas at densities n(H$_2$) $>10^7$ cm$^{-3}$. Conclusions. The first detection of this N$_2$H$^+$ (7-6) line at parsec-scales demonstrates the extreme density conditions of the star-forming gas in young massive clusters such as the ONC. Our results highlight the unique combination of sensitivity and mapping capabilities of the new SEPIA660 receiver for the study of the ISM properties at high frequencies.

Efficient coding and mapping algorithms for software implementation of a real-time H.263+ compliant low bit rate video coder |
Creators: name: Erol, Berna
Publisher: name: University of British Columbia
Year: 2009

description: The growing interest in video coding applications led to the development of video coding standards. Several successful standards have emerged, such as the ITU-T H.261, H.263, ISO/EEC MPEG-1 and MPEG-2. ITU-T recently announced its latest low bit rate video coding standard, the H.263 Version 2, also known as the H.263+ standard [25]. While this new low bit rate video coding standard provides better compression performance levels than those of the former ones, it is more complex and is more computationally, demanding. In this thesis, we develop coding and mapping algorithms that improve the video coding speed performance, making a reality the software implementation of interactive real-time low bit rate video coding on the Pentium MMX general purpose processor. First, using statistical properties of low resolution and slowly varying video sequences, we manage to significantly reduce the computation times of the most computationally intensive components of video coding, particularly the DCT, the IDCT, quantization and half pixel motion search. We also map some of the SIMD (Single Instruction Multiple Data) oriented functions onto Intel's M M X architecture. The developed algorithms are implemented using our public-domain H.263+ encoder/decoder software [45]. After the algorithmic optimization and the M M X mapping, the resulting H.263+ video encoder implementation runs approximately 3 times faster than the original unoptimized public-domain encoder implementation. Moreover, our optimized H.263+ compliant video coder implementation can encode/decode more than 15 frames of a QCIF (176x144) video sequence per second without sacrificing video reproduction quality.

description: The increasing use of Internet of Things (IoT) devices generates a greater demand for data transfers and puts increased pressure on networks. Additionally, connectivity to cloud services can be costly and inefficient. Fog computing provides resources in proximity to user devices to overcome these drawbacks. However, optimisation of quality of service (QoS) in IoT applications and the management of fog resources are becoming challenging problems. This paper describes a dynamic online offloading scheme in vehicular traffic applications that require execution of delay-sensitive tasks. This paper proposes a combination of two algorithms: dynamic task scheduling (DTS) and dynamic energy control (DEC) that aim to minimise overall delay, enhance throughput of user tasks and minimise energy consumption at the fog layer while maximising the use of resource-constrained fog nodes. Compared to other schemes, our experimental results show that these algorithms can reduce the delay by up to 80.79% and reduce energy consumption by up to 66.39% in fog nodes. Additionally, this approach enhances task execution throughput by 40.88%.

description: Large software systems tune hundreds of 'constants' to optimize their runtime performance. These values are commonly derived through intuition, lab tests, or A/B tests. A 'one-size-fits-all' approach is often sub-optimal as the best value depends on runtime context. In this paper, we provide an experimental approach to replace constants with learned contextual functions for Skype - a widely used real-time communication (RTC) application. We present Resonance, a system based on contextual bandits (CB). We describe experiences from three real-world experiments: applying it to the audio, video, and transport components in Skype. We surface a unique and practical challenge of performing machine learning (ML) inference in large software systems written using encapsulation principles. Finally, we open-source FeatureBroker, a library to reduce the friction in adopting ML models in such development environments

description: Triggered by experimentally driven renewed interest in hyperon properties we address the subject of weak radiative hyperon decays (WRHD). We start with the issue of Hara's theorem and briefly discuss the question of its possible evasion. Then, we give a short review of the story of vector-meson-dominance (VMD) approach to WRHD. We stress the shift from the Hara's-theorem-violating to Hara's-theorem-satisfying version of the VMD approach that did occur over time. Finally, spurred by a recent theoretical paper, we discuss the pole model description of WRHD, putting special attention to the issue of the contributions from the intermediate $Λ(1405)$ state. We point out that the measurement of the $Λ\to n γ$ decay asymmetry could resolve the encountered ambiguities and definitely answer the question of whether Hara's theorem is violated or not.
