description: Disk solids are critical in many planet formation processes, however, their effect on planet migration remains largely unexplored. Here we assess for the first time this important issue by building on the systematic measurements of dust torques on an embedded planet by Benitez-Llambay & Pessah (2018). Adopting standard models for the gaseous disk and its solid content, we quantify the impact of the dust torque for a wide range of conditions describing the disk/planet system. We show that the total torque can be positive and revert inward planet migration for planetary cores with $M_{\rm p} \lesssim 10 M_\oplus$. We compute formation tracks for low-mass embryos for conditions usually invoked when modeling planet formation processes. Our most important conclusion is that dust torques can have a significant impact on the migration and formation history of planetary embryos. The most important implications of our findings are: $\it{i})$ For nominal dust-to-gas mass ratios $ε\simeq 0.01$, low-mass planets migrate outwards beyond the water ice-line if most of the mass in solids is in particles with Stokes numbers St $\simeq 0.1$. $\it{ii})$. For $ε\gtrsim 0.02-0.05$, solids with small Stokes numbers, St $\simeq 0.01$, can play a dominant role if most of the mass is in those particles. $\it{iii})$ Dust torques have the potential to enable low-mass planetary cores formed in the inner disk to migrate outwards and act as the seed for massive planets at distances of tens of au.

title: Comparing accelerometer processing metrics for physical activity classification accuracy using machine learning methods
Creators: name: Musa, Sumayyah Bamidele
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: The purpose of this study was to compare the performance of three accelerometer processing metrics, Euclidean Norm Minus One (ENMO), ActiGraph Counts, and Monitor Independent Movement Summary (MIMS) units, in classifying physical activity using Random Forest (RF) and k-Nearest Neighbors (KNN) machine learning models, as well as to investigate the effect of hyperparameter tuning and feature selection on each processing metric. The dataset was sourced from a laboratory-based protocol involving raw acceleration data from 50 participants who held a smartphone device in their right hand while completing six activities. Findings indicated that even though the acceleration metrics performed well above 80% accuracy with both RF and KNN, the best performance was achieved with ENMO and the raw data as features. Additional accuracy of between 1% to 5% was achieved when the model hyperparameters were tuned before classification, and there was no difference when other features were included in the classification. In conclusion, ENMO is the best acceleration metric for classifying PA from accelerometers. Tuning the models and using a few selected features affected the models' accuracy.
The black hole binary V404 Cygni: an obscured AGN analogue

description: Typical black hole binaries in outburst show spectral states and transitions, characterized by a clear connection between the inflow onto the black hole and outflow from its vicinity. The transient stellar mass black hole binary V404 Cyg apparently does not fit in this picture. Its outbursts are characterized by intense flares and intermittent low-flux states, with a dynamical range of several orders of magnitude on timescales of hours. During the 2015 June-July X-ray outburst a joint Swift and INTEGRAL observing campaign captured V404 Cyg in one of these low-flux states. The simultaneous Swift/XRT and INTEGRAL/JEM-X/ISGRI spectrum is reminiscent of that of obscured/absorbed AGN. It can be modeled as a Comptonization spectrum, heavily absorbed by a partial covering, high-column density material ($N_\textrm{H} \approx 1.4\times10^{24}\,\textrm{cm}^{-2}$), and a dominant reflection component, including a narrow Iron-K$α$ line. Such spectral distribution can be produced by a geometrically thick accretion flow able to launch a clumpy mass outflow, likely responsible for both the high intrinsic absorption and the intense reflection emission observed. Similarly to what happens in certain obscured AGN, the low-flux states might not be solely related to a decrease in the intrinsic luminosity, but could instead be caused by an almost complete obscuration of the inner accretion flow.

description: Multiwavelength observations of the propagating disturbances (PDs), discovered by Atmospheric Imaging Assembly (AIA) onboard Solar Dynamics Observatory (SDO), are analyzed to determine its driving mechanism and physical nature. Two magnetic strands in the localised corona are observed to approach and merge with each other followed by the generation of brightening, which further propagates in a cusp-shaped magnetic channel. Differential emission measure analysis shows an occurrence of heating in this region-of-interest (ROI). We extrapolate potential magnetic field lines at coronal heights from observed Helioseismic and Magnetic Imager (HMI) vector magnetogram via Green's function method using MPI-AMRVAC. We analyze the field to locate magnetic nulls and quasi-separatrix layers (QSLs) which are preferential locations for magnetic reconnection. Dominant QSLs including a magnetic null are found to exist and match the geometry followed by PDs, therefore, it provides conclusive evidence of magnetic reconnection. In addition, spectroscopic analysis of Interface Region Imaging Spectrograph (IRIS) Si IV 1393.77 Å line profiles show a rise of line-width in the same time range depicting presence of mass motion in the observed cusp-shaped region. PDs are observed to exhibit periodicities of around four minutes. The speeds of PDs measured by Surfing Transform Technique are almost close to each other in four different SDO/AIA bandpasses, i.e., 304, 171, 193 and 131 Å excluding the interpretation of PDs in terms of slow magnetoacoustic waves. We describe comprehensively the observed PDs as quasi-periodic plasma flows generated due to periodic reconnection in vicinity of a coronal magnetic null.

description: Two mango varieties namely Kent and Neohera(NE1) were subjected to analysis and jam was manufactured. Mango pulp was extracted and cooked using pan kettles, and then sugar, citric acid, commercial pectin, and sodium benzoate were added during cooking. Mango jams were packed into glass jars then stored at room temperature (30±5ºC), refrigerator (5±2ºC) and deep freezer (-18ºC) for four months. The results revealed that Kent mango had the highest pulp content (72.9%) its pulp had the highest total soluble solids (17.0°Brix), highest acidity (0.56%) and lowest pH (3.54) while NE1 Mango had high reducing sugars (2.59%) and total sugars (10.85%). Mango jams were prepared and analyzed for physicochemical, microbial and sensory parameters at 30 days storage interval for 120 days. The sensory evaluation of mango jams tested at zero time (fresh) showed that Neohera(NE1) jam was superior in color and flavor, while Kent jam was superior in consistency and overall acceptability. The organoleptic composition of the two mango jams compared to the commercial jam showed that the kent mango jams are comparable to the highest quality jam in Ethiopia and better than the other imported commercial jam. No detectable yeast, mold and negligible total viable count were observed in all mango jam samples during storage period. A statistical model was used to optimize the factor levels for highest acceptability to produce Kent mango jam. Keywords: Jam, Mango, Optimization, Production.

description: Starting from a new factorization of the frequencydomain modal expansion coefficients, we generate analytical expressions in time-domain for the various quantities of interest of a biconical antenna of arbitrary length and cone angle. In particular, expressions are generated for the impulse response of feed current and the radiated fields as well as the transient effective length. Comparison with measured results available in the literature is carried out for the antenna effective length. The response due to any other feed voltage pulse can be obtained in terms of the impulse response via convolution. Results are presented for a Gaussian and a fast-rising feed voltage pulse. For the fast rising feed voltage pulse, the transient radiated energy density is shown to decay less rapidly than as inverse square distance over significant distances from the antenna. The expressions presented in the paper are all general and exact and not subject to any analytical approximations.

description: Streams, or infinite sequences, are infinite objects of a very simple type, yet they have a rich theory partly due to their ubiquity in mathematics and computer science. Stream differential equations are a coinductive method for specifying streams and stream operations, and their theory has been developed in many papers over the past two decades. In this paper we present a survey of the many results in this area. Our focus is on the classification of different formats of stream differential equations, their solution methods, and the classes of streams they can define. Moreover, we describe in detail the connection between the so-called syntactic solution method and abstract GSOS.

Year: 2022
Subjects: subject: Human capital

description: The COVID-19 pandemic has resulted in vast and prolonged challenges to all aspects of life including individual, social, economic, and business activities. Following a year of mandatory closures and quarantine, organizational management are required to shift focus to remote working and care for employees in response to the COVID-19 pandemic. This study examines the impacts of the COVID-19 pandemic on employees from a multidisciplinary approach to Human Capital Management (HCM). After collecting qualitative data from employees in the Departments of Human Resources, this study examines questions of 1) how do Human Resources professionals perceive to be the changing mode of Human Capital Management because of the pandemic; 2) how do organizational support and regulations play a role in the process of transformation; and 3) what are future directions of the transformation organizations can adopt to optimize their Human Capital. The results showed the importance of investing in talents for organizations' long-term success in the aspects of Work From Home Adaptation, Cooperative-level Coping mechanisms, and future directions for HCM. 5 Future directions of improvement for organizations' long-term success are: 1) creating guidelines on remote working to minimize potential isolation, 2) elevating employees’ overall performance through up-skill and re-skill training, 3) utilizing employees’ work satisfaction to increase productivity, 4) providing more mental health-related support, and 5) providing flexibility for employees.
Turbulent transport in 2D collisionless guide field reconnection

description: Transport in collisionless plasmas is usually called anomalous, being due to the interaction between the particles and the self-generated turbulence by their collective interactions. Because of its relevance for astrophysical and space plasmas, we explore the excitation of turbulence in current sheets prone to component- or guide-field reconnection, a process not well understood, yet. We analyze the anomalous transport properties by using 2.5D Particle-in-Cell (PiC) code simulations. We split off the mean, slow variation (in contrast to the fast turbulent fluctuations) of the macroscopic observables and determine the main transport terms of the generalized Ohm's law. We verify our findings by comparing with the independently determined slowing-down rate of the macroscopic currents and with the transport terms obtained by the first order correlations of the turbulent fluctuations. We find that the turbulence is most intense in the "low density" separatrix region of guide-field reconnection. It is excited by streaming instabilities, it is mainly electrostatic, "patchy" in space and so is the associated quasi-periodic anomalous transport. The remaining irreversible anomalous resistivity can be parametrized by an effective collision frequency ranging from the local ion-cyclotron to the lower-hybrid frequency. The contributions to the parallel and the perpendicular (to the magnetic field) components of the slowly varying, DC-electric fields, balanced by the turbulence, are similar. This anomalous electric field is, however, smaller than the contributions of the off-diagonal pressure and electron inertia terms of the Ohm's law. This result can now be verified by in-situ measurements of the turbulence, in and around the magnetic reconnection regions of the Earth's magnetosphere by the multi-spacecraft mission MMS and in laboratory experiments like MRX and VINETA-II.

description: Eremosparton songoricum (Litv.) Vass. is an endemic and extremely drought-resistant desert plant with populations that are gradually declining due to the failure of sexual recruitment. The effects of drought stress on the seed germination and physiological characteristics of seeds and seedlings were investigated. The results showed that the germination percentage decreased with an increase of polyethylene glycol 6000 (PEG) concentration: -0.3 MPa (5 % PEG) had a promoting effect on seed germination, -0.9 MPa (15 % PEG)dramatically reduced germination, and -1.8 MPa (30 % PEG) was the threshold for E. songoricum germination. However, the contents of proline and soluble sugars and the activity of CAT increased with increasing PEG concentrations. At the young seedling stage, the proline content and CAT, SOD and POD activities all increased at 2 h and then decreased; except for a decrease at 2 h, the MDA content also increased compared to the control (0 h). These results indicated that 2 h may be a key response time point for E. songoricum to resist drought stress. The above results demonstrate that drought stress can suppress and delay the germination of E. songoricum and that the seeds accumulate osmolytes and augment the activity of antioxidative enzymes to cope with drought injury. E. songoricum seedlings are sensitive to water stress and can quickly respond to drought but cannot tolerate drought for an extended period. Although such physiological and biochemical changes are important strategies for E. songoricum to adapt to a drought-prone environment, they may be, at least partially, responsible for the failure of sexual reproduction under natural conditions.

description: The study was conducted to assess the practices and impact of productive safety net program on the household income of small holder farmers in Tula sub city, Hawassa. Though there are other rural sub cities in and around Hawassa town, due to the extended problem of food insecurity in the area this study mainly focused on the impact of PSNP on the household income of smallholder farmers in Tula sub city. For this study the researcher employed both primary data and secondary resources. The relevant primary data were collected through tools such as Household survey questionnaire, key informant interviews and observation. The secondary data were published and unpublished articles, journals, office records, books and thesis. The study participants were PSNP beneficiary farmers, development agents, kebele administrators and early warning and food security office coordinator and employees. The data collected through primary and secondary sources were thematically organized and analyzed through triangulation to increase the accuracy of the study finding. The study has found out that the productive safety net program has registered some improvements on aspects like beneficiaries monthly income, number of meals per day, monthly food consumption and availability of community assets and no improvements on other many aspects like total crop production, number of livestock, availability of household assets, availability of production materials and the condition of using negative coping mechanisms that are put by the researcher as measures of to evaluate the impact of the program on the study area. After examining the impact of PSNP on the house hold income of small holder farmers in the study area, some recommendations were suggested by the researcher.

description: The study aims at assessment of training and development practices in private organizations (case study on OMEDAD PLC) with due emphasis on practices of TD needs assessment, TD methods, and evaluation of TD effectiveness. Accordingly, all the necessary data has been gathered from primary sources using questionnaires and interviews. Stratified sampling technique was used and the number of participants was 38 manager and non-manager employees. The researcher used descriptive analysis with the help of tables and percentages to analyze the data. The study revealed that the major weaknesses of the company in training and development practices being lack of periodical and balanced method of TD needs assessment, imbalance between on-the-job and off-the-job method of trainings, absence of trainees evaluation practice at different phases, and absence of evaluating the effectiveness of TD activities. The strengths being practicality of technical trainings, cooperation of existing staff to train new employees, and belief of top level management on the importance of TD to organizational performance. Hence, the Company need to keep up with its strengths and alleviate its weaknesses by adopting a systematic approach of TD practices.

The Effects Of Television Advertisements On Consumers Buying Decision In The Packaged Foods Industry
Creators: name: Ermyas, Saba
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Advertisement plays a major role in building, creating and sustaining brands. It helps marketers in persuading, informing and reminding both potential and existing customers towards making a purchase decision. It contributes in shaping dreams and aspirations of consumers and helps them make conscious product and brand decisions. This study aims to explore the effects of advertising on consumers purchasing decision of packaged-foods in Addis Ababa. The research adopted deductive research approach and quantitate research methods. 384 close ended questionnaires were distributed to consumers of supermarkets in Addis Ababa out of which 331 questionnaires were collected and analysed. The respondents were selected using simple random sampling. Questionnaires were distributed to walk-in consumers on a random basis giving all consumers of the supermarkets equal chance of being selected. The data were analysed using descriptive statistics (frequency, percentage) and inferential statistics like correlation and multiple regression with the help of SPSS version 20.0. The findings revealed that there are positive and significant relationships between characteristics of advertising messages, source of advertisement, media used for advertising and purchasing decision. Among media used for advertising, television is the most powerful media in influencing purchasing decision. Moreover, the finding indicated 45.4% of purchasing decision is explained by advertising. Finally, this study recommends actions for companies in tailoring their advertising strategies to stand out of the intense competition in the market for an increased sales volume and market share and earn good value for money.

description: The scoping review will present and summarize published research on the terms 'generational segregation' and 'ageism', and especially on the connection between them. The overall purpose of this scoping exercise is to review which research and studies have been carried out from 1969 to date around these terms. For which purpose? Getting to know what has been investigated or studied will allow not only to assess the trajectory of the terms 'age segregation' and 'ageism/generationism', but also to unveil the connection between these terms. This connection will be helpful to advance the intergenerational studies field in general, and the planning of intergenerational programs and spaces in particular. Findings from this review will support the formulation of policies, programs and services that favor the development and proliferation of intergenerational work geared towards reducing age and generational segregation, as well as ageism.

description: The non-stationary relaxation and physical ageing in the diffusion-limited erosion process ({\sc dle}) is studied through the exact solution of its Langevin equation, in $d$ spatial dimensions. The dynamical exponent $z=1$, the growth exponent $β=\max(0,(1-d)/2)$ and the ageing exponents $a=b=d-1$ and $λ_C=λ_R=d$ are found. In $d=1$ spatial dimension, a new representation of the meta-conformal Lie algebra, isomorphic to $\mathfrak{sl}(2,\mathbb{R})\oplus\mathfrak{sl}(2,\mathbb{R})$, acts as a dynamical symmetry of the noise-averaged {\sc dle} Langevin equation. Its infinitesimal generators are non-local in space. The exact form of the full time-space dependence of the two-time response function of {\sc dle} is reproduced for $d=1$ from this symmetry. The relationship to the terrace-step-kink model of vicinal surfaces is discussed.

description: In this paper we propose a tokenization algorithm of Reversible Hybrid type, as defined in PCI DSS guidelines for designing a tokenization solution, based on a block cipher with a secret key and (possibly public) additional input. We provide some formal proofs of security for it, which imply our algorithm satisfies the most significant security requirements described in PCI DSS tokenization guidelines. Finally, we give an instantiation with concrete cryptographic primitives and fixed length of the PAN, and we analyze its efficiency and security.

description: Der Faktor Wissen gilt heute als Schlüsselressource für die Entwicklung moderner Gesellschaften. Die regionale Wettbewerbsfähigkeit basiert im Wesentlichen auf der Wissensinfrastruktur und den Verflechtungen der Wissensakteure untereinander sowie mit Wirtschaft und Gesellschaft. Neben den wissensintensiven Dienstleistern und den Hochschulen, die häufig im Zusammenhang mit wissensbasierter Regionalentwicklung betrachtet werden, existiert mit den außeruniversitären Forschungsinstitutionen ein weiterer bedeutender Bereich des Wissenssystems. Die Arbeit untersucht vor diesem Hintergrund die Rolle außeruniversitärer Forschungseinrichtungen für die regionale Wissensproduktion und Entwicklungsdynamik. Am Beispiel des Untersuchungsraumes Ruhrgebiet fokussiert die Arbeit auf die Frage nach der regionalen Einbettung der Institute sowie ihren Vernetzungen. Dabei werden nicht nur naturwissenschaftlich-technisch orientierte Forschungseinrichtungen beleuchtet sondern auch solche mit geistes- und sozialwissenschaftlicher Ausrichtung. Dies erlaubt einen Vergleich der Forschungstypen und -disziplinen im Hinblick auf ihre Kooperationsbeziehungen. Die empirische Untersuchung ist als explorativ angelegte Fallstudie konzipiert, die insgesamt zehn verschiedene außeruniversitäre Forschungsinstitute im Ruhrgebiet in den Blick nimmt. Die Analyse stützt sich dabei vor allem auf die qualitativen Methoden der Experteninterviews und der qualitativen Netzwerkanalyse. Die Arbeit stellt die regionalen Wirkungen der Forschungsinstitute differenziert dar und zeigt auf, inwieweit diese sich in der Generierung und der Vermittlung des Wissens unterscheiden. Es zeigt sich, dass die Mehrheit der Einrichtungen sowohl regional als auch global vernetzt sind und persönliche Beziehungen bei der Anbahnung institutioneller Kooperationen eine bedeutende Rolle spielen. Beim Vergleich der Wissenschaftsdisziplinen wird deutlich, dass gerade auch die geistes- und sozialwissenschaftlichen Forschungsinstitute beträchtliche regionale (Wissens-)Transferleistungen erbringen. Abschließend wird in der Arbeit eine Typenbildung vorgenommen, welche die Forschungsinstitute in drei Organisationstypen in Bezug auf Wissensproduktion und Wissenstransfer im räumlichen Kontext differenziert. Diese Typologie, die zwischen dem (1) standortungebundenen Wissensproduzenten, (2) regionalen Wissensagenten und (3) Wissensvernetzer unterscheidet, kann dabei einen Anknüpfungspunkt für weitergehende Untersuchungen in diesem Themenfeld darstellen.

description: Neural networks often learn spurious correlations when exposed to biased training data, leading to poor performance on out-of-distribution data. A biased dataset can be divided, according to biased features, into bias-aligned samples (i.e., with biased features) and bias-conflicting samples (i.e., without biased features). Recent debiasing works typically assume that no bias label is available during the training phase, as obtaining such information is challenging and labor-intensive. Following this unsupervised assumption, existing methods usually train two models: a biased model specialized to learn biased features and a target model that uses information from the biased model for debiasing. This paper first presents experimental analyses revealing that the existing biased models overfit to bias-conflicting samples in the training data, which negatively impacts the debiasing performance of the target models. To address this issue, we propose a straightforward and effective method called Echoes, which trains a biased model and a target model with a different strategy. We construct an "echo chamber" environment by reducing the weights of samples which are misclassified by the biased model, to ensure the biased model fully learns the biased features without overfitting to the bias-conflicting samples. The biased model then assigns lower weights on the bias-conflicting samples. Subsequently, we use the inverse of the sample weights of the biased model for training the target model. Experiments show that our approach achieves superior debiasing results compared to the existing baselines on both synthetic and real-world datasets.

Regulatory impact analysis

description: This research proposes a new regulatory framework for an interruptible load program aimed at large users in the Argentine electricity market. A Regulatory Impact Analysis (RIA) approach is utilized to assess the impact of this new regulation across different perspectives: technical, economic, energy and environment, and regulatory. The technical analysis provides insights into the alignment of peak demand hours of the system and large users. It identifies 266 MW as the technical potential for load interruption, which could meet almost 1% of the peak demand in 2021. Only 15 large companies are expected to contribute 35% of the interruptible load, and the chemical, rubber, plastic, and other non-metallic mineral materials industries show the most promising potential. The economic approach suggests an initial price cap of 106 USD/MWh (3-hour events) for interruptible load payments. The program would have generated greater monetary savings during the winter periods of 2021, indicating that seasonal variations in energy demand may impact the program's effectiveness. The section on energy and environment underscores that the geographical distribution of potential providers and costly generation is a significant challenge. While some regions could be balanced, others, such as the Patagonic region, may present a barrier to fully implementing reductions. Gas and steam turbines are the technologies affected by the program, with natural gas and gas oil being the most frequently reduced fuels. The characteristics of the electricity matrix at the time of program application are crucial for achieving emission savings. The regulatory analysis emphasizes the importance of designing an effective regulatory framework for the success of the program. It identifies the shortcomings of the current regulation and confirms the necessity for significant changes or the creation of a new one. To mitigate risks associated with the implementation, three essential approaches are identified: leveraging best practices from successful programs, applying transparent stakeholder consultation processes, and developing detailed and comprehensive rules. These findings can provide valuable insights for policymakers seeking to improve the regulatory framework for interruptible load programs in the electricity market. Finally, the study limitations and potential areas for future research are discussed to offer guidance for further investigation.
Balancing High-Load Scenarios with Next Cell Predictions and Mobility Pattern Recognition

description: Knowing where a mobile user will be next can deliver a tremendous increase in network performance under high load, as this knowledge enables pro-active load balancing. To derive this information, sequences of traversed cells are fed into pattern detection algorithms. After the training phase the learned model predicts each user’s next cell. Even for complex scenarios, the prediction accuracy can exceed 90%. Predictions are used to rearrange mobile connections in a simulated high- load scenario centered around an event at a soccer stadium. To prevent call drops for mobile users targeting the stadium, apropriate resources in the predicted next cell are reserved. The results exceed 20% in improvements for throughput and call drop rates, enabling the network to bear a much higher load before stalling.

description: The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried out near-infrared multi-object spectroscopy on the ejecta knots located in the "northeastern (NE) jet" and the "Fe K plume" regions, which are two distinct features in the outer eastern area of the remnant. Our study reveals that the knots exhibit varying ratios of [S II] 1.03 $μ$m, [P II] 1.189 $μ$m, and [Fe II] 1.257 $μ$m lines depending on their locations within the remnant, suggesting regional differences in elemental composition. Notably, the knots in the NE jet are mostly 'S-rich' with weak or no [P II] lines, implying that they originated below the explosive Ne burning layer, consistent with the results of previous studies. We detected no ejecta knots exhibiting only [Fe II] lines in the NE jet area that are expected in the jet-driven SN explosion model. Instead, we discovered a dozen 'Fe-rich' knots in the Fe K plume area. We propose that they are dense knots produced by a complete Si burning with $α$-rich freezeout in the innermost region of the progenitor and ejected with the diffuse X-ray emitting Fe ejecta but decoupled after crossing the reverse shock. In addition to these metal-rich ejecta knots, several knots emitting only He I 1.083 $μ$m lines were detected, and their origin remains unclear. We also detected three extended H emission features of circumstellar or interstellar origin in this area and discuss its association with the supernova remnant.
