description: Background: Globally there are 3.3 million Children under fifteenyears of age living with human-immune virus infection each year. Itcan be transmitted from human-immune virus positive mothers to her child during pregnancy, childbirth and breast feeding. Without treatment, the likelihood of itstransmissionfrom mother-to-child is fifteen toforty five percent. Therefore, the purpose of this study was to reveal theitsprevalence among infants born to sero positive mothers. Method: Facility based cross-sectional study was employed among 220human-immune virusexposed infants enrolled from July 1, 2014- June30, 2018 in Asella town Health facilities. Data werecollected from all exposed infant having human-immune virus Deoxyribonucleic Acid polymerase chain reaction test. The collected data was coded and entered in to EPI info version 7.0, then cleaned and exported to SPSS version 21. Descriptive statistics were used to describe findings, both binary and then multiple logistic regressions were used to identify the associated factors. A 95% confidence intervalwith Adjusted odd ratiowas used to measure the strengths of association and a p-value <0.05 was used to determine the statistical significance in the final model. Result: The study revealed that 2.3% of the infants born from humanimmune virus seropositive mothers were found to be human-immune virus positive. Infants whose mothers started Antiretroviral at post-partum period 46.794, 95%CI (6.521, 321.590)). Conclusion:The prevalence of human-immune virus infection among exposed infants was less than globally expected for mothers only breastfeed their infants to acceptable level. Initiating Antiretroviral during post-partum period was the factor associated with mother-to-child transmission. Therefore, mothers should start Antiretroviral early to bring mother-to-child transmission to zero level and further investigations are recommended to identify more predictors.

description: Living cell segmentation from bright-field light microscopy images is challenging due to the image complexity and temporal changes in the living cells. Recently developed deep learning (DL)-based methods became popular in medical and microscopy image segmentation tasks due to their success and promising outcomes. The main objective of this paper is to develop a deep learning, U-Net-based method to segment the living cells of the HeLa line in bright-field transmitted light microscopy. To find the most suitable architecture for our datasets, a residual attention U-Net was proposed and compared with an attention and a simple U-Net architecture. The attention mechanism highlights the remarkable features and suppresses activations in the irrelevant image regions. The residual mechanism overcomes with vanishing gradient problem. The Mean-IoU score for our datasets reaches 0.9505, 0.9524, and 0.9530 for the simple, attention, and residual attention U-Net, respectively. The most accurate semantic segmentation results was achieved in the Mean-IoU and Dice metrics by applying the residual and attention mechanisms together. The watershed method applied to this best -- Residual Attention -- semantic segmentation result gave the segmentation with the specific information for each cell.

description: For a multipartite quantum state, the maximal violation of all Bell inequalities constitutes a measure of its nonlocality [Loubenets, J. Math. Phys. 53, 022201 (2012)]. In the present article, for the maximal violation of Bell inequalities by a pure bipartite state, possibly infinite-dimensional, we derive a new upper bound expressed in terms of the Schmidt coefficients of this state. This new upper bound allows us also to specify general analytical relations between the maximal violation of Bell inequalities by a bipartite quantum state, pure or mixed, and such entanglement measures for this state as "negativity" and "concurrence". To our knowledge, no any general analytical relations between measures for bipartite nonlocality and entanglement have been reported in the literature though, for a general bipartite state, specifically such relations are important for the entanglement certification and quantification scenarios. As an example, we apply our new results to finding upper bounds on nonlocality of bipartite coherent states intensively discussed last years in the literature in view of their experimental implementations.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2010
Subjects: experiential learning; active learning classrooms; critical thinking; interdisciplinary learning; collaborative learning

description: This interactive session will outline a view of problem-based learning (PBL) that focuses on PBL not only as a practical method but also as an ethical stance: that is, not merely as a chance to move from acquiring knowledge to applying it, but even more as a means of helping students experience what knowledge is good for and try out ways that people with the particular kinds of knowledge at issue think, speak, and act. The two PBL techniques the presenters will describe and demonstrateâ€”the post-class problem paper and the in-class 2-minute paperâ€”draw on the scholarship and practical suggestions in Ken Bainâ€™s What the Best College Teachers Do (Harvard UP, 2004) and in Richard J. Lightâ€™s Making the Most of College: Students Speak Their Minds (Harvard UP, 2004). The session will also integrate the presentersâ€™ model of democratic dialogue in the classroom, an approach to classroom interaction that complements PBL as an ethical stance and that links PBL to the ideal of â€œeducation as a practice of freedomâ€ (bell hooks). Topics will include ways to:
â€¢ Implement two useful PBL methods
â€¢ Create a framework for critical thinking and civil discourse that supports the highly
interactive nature of PBL
â€¢ Build on successes and avoid pitfalls of PBL approaches
â€¢ Implement PBL in disciplinary and interdisciplinary environments
â€¢ Encourage students to open themselves to new ways of thinking about complex issues
â€¢ Address the classroom management and personal issues that arise when students express
controversial opinions, beliefs, or biases within the PBL framework

description: Most modern "Intelligent" buildings is focused on enhancing the users control when interacting with the building, and simplifying this interaction. BIIIB is different because it analyses its users and then take over the control of the building based on this analysis. We have implemented a simple AI which controls the lighting in the the ground floor hallway of building 322. In this experiment we have managed to cut the time the lamps are turned on in half, without causing any sort of irritation or discomfort to the users*. *that is excluding the entire development phases, and the endless amount of system crashes.

description: expenditure on economic growth using time series data from 1970 to 2019 in Ethiopia. To this end, unrestricted error correction model (UECM) and single equation autoregressive distributed lag model (ARDL) was used to identify short run and long run impact of government expenditure on economic growth respectively. The estimation result envisaged that capital expenditure has distorting effect in the short run, while it promotes growth in the long run. The study also revealed that government recurrent expenditure has positive effect in the short run, but has no positive effect and implication on growth in the long run. Similarly, debt financed capital expenditure crowd in economic growth in the short run even though it crowds out economic growth in the longrun. Therefore, government should pay due attention to development project management to enhance the effectiveness of capital expenditure in achieving sustainable economic growth and closely supervise the adverse effect of recurrent expenditure to maintain macroeconomic stability.

description: We examine the cradle-to-grave magnetic evolution of 10 bipolar ephemeral active regions (BEARs) in solar coronal holes, especially aspects of the magnetic evolution leading to each of 43 obvious microflare events. The data are from Solar Dynamics Observatory: 211 A coronal EUV images and line-of-sight photospheric magnetograms. We find evidence that (1) each microflare event is a magnetic explosion that results in a miniature flare arcade astride the polarity inversion line (PIL) of the explosive lobe of the BEARs anemone magnetic field; (2) relative to the BEAR's emerged flux-rope omega loop, the anemone's explosive lobe can be an inside lobe, an outside lobe, or an inside & outside lobe; (3) 5 events are confined explosions, 20 events are mostly-confined explosions, and 18 events are blowout explosions, which are miniatures of the magnetic explosions that make coronal mass ejections (CMEs); (4) contrary to the expectation of Moore et al (2010), none of the 18 blowout events explode from inside the BEARs omega loop during the omega loops emergence; (5) before and during each of the 43 microflare events there is magnetic flux cancellation at the PIL of the anemone's explosive lobe. From finding evident flux cancellation at the underlying PIL before and during all 43 microflare events - together with BEARs evidently being miniatures of all larger solar bipolar active regions - we expect that in essentially the same way, flux cancellation in sunspot active regions prepares and triggers the magnetic explosions for many major flares and CMEs.

Automating scattering amplitudes with chirality flow

Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Recently we introduced the chirality-flow formalism, a method which builds on the spinor-helicity formalism and is inspired by the color-flow idea in QCD. With this formalism, Feynman rules and diagrams are simplified to the extent that it is often possible to immediately, by hand, write down a helicity amplitude given a Feynman diagram. In this paper we show that the method can also speed up numerical evaluation of scattering amplitudes by considering $e^+ e^-$ going to $n$ photons in a MadGraph-based tree-level implementation. We find that the computation time is reduced by roughly a factor ten for six photons, and that it scales better with the number of external particles than the default MadGraph5_aMC@NLO implementation. This performance gain is in part attributed to the more compact Lorentz structures involved, and in part due to a transparent choice of gauge reference vectors which reduces the number of Feynman diagrams considered.

description: Consensus, collaboration, and multiple authorship are often problematic for students. Some frequent problems include finding a common time to meet face-to-face, circulating and editing multiple versions of a document, upload & download, and document formatting, to name just a few. Googledocs provides one format, one place for a document that can be edited and co-authored by people from their own office or home at their convenience. Student team work is facilitated during and after class sessions by having one document that can be asynchronously created, developed, and editedâ€¦ eliminating multiple drafts. In Googledocs a â€˜revision historyâ€™ is maintained, so nothing from previous versions of the document is lost. This session should appeal to GMU faculty who have class assignments that call for team problem solving, consensus building, or collaboration. I will present the results of using Googledocs as a consensus building & collaborative tool for students in classes. Coming from the College of Education, I will identify what worked and what didn't for students in my classes who are classroom teachers, then provide some guidance and lessons learned. Models and exemplars will be shared, and faculty will have an opportunity to â€˜try outâ€™ the collaboration tool in the workshop. Googledocs can also assist faculty with work outside of classes. Faculty committee and department work is facilitated during and after meetings by having a place for documents that can be asynchronously created, developed, and editedâ€¦ eliminating multiple drafts. A discussion of this additional application of the technology should appeal to GMU faculty for their department meetings and committee work â€“ anytime working documents are involved. The session closes with peer-to-peer discussion and Q&A regarding potential applications of the technology.

description: Low level of household saving habit and its determinants demand public attentions for effective policy interventions. This study was conducted to investigate determinants of household saving in urban Oromia with specific reference to Assela Town. To this end, primary data was collected from household using multistage sampling. First, based on strata of whole peripheries), out of eight kebeles were selected purposively. Then, using simple random sampling household were proportionately selected from sex of household head -based strata formed for selected kebele. Accordingly, 394 households of which 286(72.6%) and 108 (27.4%) were male and female respectively were selected. 240 (60.9%) of the respondents were having saving habit and the other were not. Both descriptive and econometric methods were employed to analyze data. Binary logit model was utilized to identify determinants of households saving behavior. Three interrelated models (log odds, odds ratio, and predicted probability) were estimated. The results of the descriptive analyses shows that 61% of sample households practiced saving and the common challenges were low income, preference of investment in kind and other business, high expenditure. Besides, econometric analyses shows that 15 of 17 stated variables were found to be statistically significant in affecting probability of household saving. Specifically, average income has positive, but age and dependency ratio were found to be negative effect on probability of household saving. Furthermore, being married, widowed, or divorced, were higher probability of saving than the single one. Besides, improvements in level of education to certificate, diploma or degree and above have higher probability than illiterate once. Being self-employed household were more savers than government and private sector employee. Being male, alcohol user, being non house owner have lower tendency of household saving than their counterpart. The study recommended that concerned bodies should design capacity building program through creating awareness on saving, financial planning and budgeting.

Projects and/or Papers? Finding a Good Fit

Subjects: pedagogy; student writing;

description: Teaching often presents instructors with dilemmas and decisions related to requiring a project, a paper or both. This interactive session will include discussion and offer hints, the opportunity to develop a plan for a course, and time to give and receive peer feedback.
The session will consider four core ideas:
â€¢ Determining key decision criteria for inclusion of a project/paper /or both in a particular course.
â€¢ Framing the scope of a project /paper and number of students per project/paper
â€¢ Choosing â€˜deliverablesâ€™ and time frames
â€¢ Selecting evaluation criteria
I believe faculty will be interested as I am sure that others have had the experience of being either overwhelmed by what happens when a great idea for projects balloons a bit out of control or feeling let-down that there is far less apparent learning from the project than expected. In my experience, any gathering of Mason faculty to talk about teaching engenders great exchange of ideas and experiences, and this session offers a framework for that sharing related to project or paper assignments, as well as some practical hints. In fact, my expectation is that this session will yield a group of ideas that can be shared via the CTE web. The structural thread for this session is backward design as the base for decision criteria.-By looking at the desired student learning, and considering Bloomâ€™s categories, or Perryâ€™s developmental scale among other ideas, an instructor can design assignments for projects/papers leading to the desired learning. Framing the scope involves both the â€˜sizeâ€™ of the assignment, and its focus, along with the desired learning. Scope can inform the choices for group or individual work. Deliverables are demonstrations of students learning.. The quality of those deliverables is influenced by an appropriate time frame. For example, several smaller pieces of work may build to a stronger final project or paper. Elements of deliverables can be many things, and when the focus is on the desired student learning, these elements =become clearer to both instructor and students. One valuable attribute of backward design is that evaluation criteria are often self evident. Participants will begin by considering a desired student learning, and using the four core ideas. Faculty discussion, idea exchange, and reflection will contribute to a session experience that can be applied to additional course or syllabi development.

Creators: name: Admasu, Mesfin
Publisher: name: Arsi Journal of Science and Innovation
Year: 2022

description: The purpose of this study was to assess the implementation of contextual vocabulary teaching in EFL (English as a Foreign Language) class. Grade twelve English teachers and students in Adama Hawas Preparatory School were the participants of the study. Qualitative method was employed to conduct the study and such instruments as classroom observation, textbook analysis, interviews and focus group discussions were used to collect the data. e interview; textbook analysis was used to assess whether the text had enough instruction which enables teachers help students learn the vocabulary from the classroom observation. Added to this, focus group discussion was used to ed to develop from contextual vocabulary instruction. Thus, the findings indicate that teachers include contextual vocabulary instruction in EFL classes to teach vocabulary. However, context-based vocabulary instruction has not been given the attention it deserves in grade twelve English textbook; the activities which are presented in matching formats also lack adequate depth.Therefore chance of learning new words from context is limited both in quantity and quality. What students want to implement in the actual classroom teaching background knowledge and mother tongue influence (students tend to directly translate the meaning of the word into their mother tongue) were also factors that impede contextual vocabulary teaching practice. The vocabulary instructions should be presented to help students understand the meaning of new words in multiple contexts. Therefore, students should be exposed for contextual vocabulary instruction in order to develop their word power that enables them comprehends the concept of any text

description: The Coulomb scattering between three charged pions is shown to be perturbatively calculable using scalar QED for the relative momenta accessible to high-energy experiments of particle collisions. For the triplet relative momenta, $Q_3 \gtrsim 50$ MeV/$c$, the calculated three-pion correlation function at $O(α^2)$ is very similar to the commonly-used triple-product of pair factors -- Riverside approximation. At lower $Q_3$, but above the lowest existing experimental measurement of $\sim15$ MeV/$c$, terms of $O(α^3)$ or higher are needed to obtain a convincing description of three-pion Coulomb interactions. This is in contrast to two-pion correlations, for which the known exact solution is shown to be saturated by the lower orders at comparable pair relative momenta.

description: Dairy cattle genetic improvement mainly focuses on improving reproductive performances. The improvement of dairy cattle reproductive performance increasesthe number of calves per year, decreases calving interval, and reduces the number of services per conception. The low reproductive performance of local cattle rapidly improved through crossbreeding with exotic dairy breed sires. Therefore, this research was designed to estimate the reproductive performance of crossbred dairy cattle and determine factors that influence reproductive trait performance. The reproductive performance of crossbred dairy cattle has been analyzed using farm recorded data. The AFC of crossbred dairy cows was 57.1 months, and the irth year. CI and DO of crossbred dairy cows were 422.2 and 131.4 days respectively, and the traits show a significantdifference (P<0.001) among birth year and parity. Calving year and calving seasons had a significant effect (P<0.05) on the two traits. Birth season and genotype did not show significant effect on the was found 1.5 and all the variables did not show a significant difference in the trait. The least-square mean of the traits shows a significant improvement trend across the different birth years. The higher performance record and the irregularity of the performance across birth year, and the insignificant effect of the different genotypes might be due to management and absence of selective breeding.

Management Service Initiatives as Predictors of Employees’ Job Satisfaction and Employees’ Customer Service Behaviors: The Case of Hotels in Adama City
Creators: name: Kebelo, Kassim Kimo
Publisher: name: Arsi Journal of Science and Innovation
Year: 2022

description: The study was aimed to examine management commitment initiatives as predictors of employees’ job satisfaction and customer service behaviors in Hotels of Adama city. For this purpose, out of 14 international standard hotels, 6 hotels were randomly selected using random sampling technique. The total number of employees was also obtained from the front office managers of the participating hotels, and then the required sample size was selected using stratified random sampling technique. The survey questionnaire for this study was adapted from the work of Kim, et al.(2009). The collected data were analyzed using descriptive and inferential statistics. Results of the findings revealed that Adama city hotel employees have a significant positive relationship between management commitment initiatives (organizational support, reward, empowerment, and training) and their job satisfaction. In contrast, there was no significant relationship between management commitment initiatives (reward, empowerment, and training) and employees’ service behaviors. Providing good training programs, increasing rewards, developing the empowerment, and improving the organizational support will increase employees’ job satisfaction and employees’ service behaviors.

description: We investigate the properties of 232 optical spectroscopically selected groups from the Galaxy And Mass Assembly (GAMA) survey that overlap the XXL X-ray cluster survey. X-ray aperture flux measurements combined with GAMA group data provides the largest available sample of optical groups with detailed galaxy membership information and consistently measured X-ray fluxes and upper limits. 142 of these groups are divided into three subsets based on the relative strength of X-ray and optical emission, and we see a trend in galaxy properties between these subsets: X-ray overluminous groups contain a lower fraction of both blue and star forming galaxies compared with X-ray underluminous systems. X-ray overluminous groups also have a more dominant central galaxy, with a magnitude gap between first and second ranked galaxies on average 0.22 mag larger than in underluminous groups. The central galaxy in overluminous groups also lies closer to the centre of the group. We examine a number of other structural properties of our groups, such as axis ratio, velocity dispersion, and group crossing time and find trends with X-ray emission in some of these properties despite the high stochastic noise from the limited number of group galaxies. We attribute the trends we see to the evolutionary state of groups, with X-ray overluminous systems being more dynamically evolved than underluminous groups. The X-ray overluminous groups have had more time to develop a luminous intragroup medium, quench member galaxies, and build the mass of the central galaxy through mergers compared to underluminous groups. However, a minority of X-ray underluminous groups have properties that suggest them to be dynamically mature. The lack of hot gas in these systems cannot be accounted for by high star formation efficiency, suggesting that high gas entropy resulting from feedback is the likely cause of their weak X-ray emission.

â€¢ A/V commenting takes less time and is more productive. The teacher can more readily point
out patterns of errors and teach a corresponding lesson online. This is particularly helpful for
ESL students.
â€¢ Jing reduces teacher grading burnout because commenting becomes a conversation that
addresses studentsâ€™ unique personalities and needs.
â€¢ Jing links can be made private (essay comments or test scores) or public (class lessons)
through hyperlinks.
â€¢ Teachers can supplement in-class lessons or create online lessons with video lectures.
â€¢ Video recording can include opening other web windows, Word documents, and databases to
lead students to greater comprehension.
â€¢ Individual student issues can be addressed through video, which can cut back on conference
scheduling conflicts and lengthy e-mail explanations.
â€¢ Teachers can monitor how many times a video is watched.
â€¢ Teachers can design assignments that involve students using Jing, such as student PowerPoint
presentations or Peer Review.
â€¢ Students and teachers can access, pause, and replay videos as many times as they like.

description: This project aims to optimize the solar cell by applying a new kind of material, black silicon, in order to optimize the absorption of the solar radiation. By changing the surface of the conventional solar cell absorption-material, silicon, on nanoscale, the absorption can possibly and hopefully be improved. If this is the case the next challenge in this project is to incorporate the material in a functioning solar cell, which can actually transform sunlight into electrical power.

description: We analyse the perturbative four-point amplitudes in the simplest string theory examples of T-fold backgrounds, which enjoy N=6 supersymmetries in four dimensions. There are two theories defined as asymmetric orbifolds of order 2 and 3, respectively. The perturbative spectrum and the one-loop four-point amplitudes are shown to be invariant under an arithmetic symplectic group defined over the Hurwitz (respectively Eisenstein) quaternions. The supersymmetry constraints on the low energy effective couplings are determined and we conjecture the U-duality group of the theory and the non-perturbative completion of the six-derivative coupling as a rank one theta series. We discuss the non-perturbative spectrum of BPS states in the light of our analysis.

Year: 2022

description: Background: Frontline health workers are encountering an increasing workload and risk of infection while saving lives and it was reported that infected health workers accounted for 29% of all hospitalized COVID-19 patients during early pandemic. Thus they are under psychological distress because of risk of contracting COVID-19. Objectives: To assess the perceiving stress and its associated factors towards COVID-19 outbreaks among health professionals of Asella referral and teaching hospital, Arsi zone, Oromia Region, Ethiopia, June 2020. Methods: An institutional based cross sectional study design was conducted from June 1 - 20, 2020. Simple random sampling technique and proportional allocation was used. Data was collected by trained BSc nurses in face to face by using pretested and structured questionnaire and entered into Epi-info and exported to SPSS for analysis and presented by descriptive statistics. Bivariate and multivariate binary logistic regression was used. Result: The prevalence of perceived stress was 60.8%. The married were more stressed than divorced individuals, (AOR: 1.213, 95 CI: (1.199, 3.571). Protestant (AOR: 2.552, 95% CI: (1.098, 10.846) stressed more than Waaqeffata religion followers. Amhara (AOR: 1.757, 95% CI: (1.337, 9.158) more likely stressed than Siltey ethnicity. Conclusion: This study revealed health professionals found to have high perceived stress. Religion, marital status and ethnicity were found to have a statistically significant association with perceived stress. Early screening and intervention of psychological stress of health professionals were highly recommended.

description: Supernovae emit large fluxes of neutrinos which can be detected by detectors on Earth. Future tonne-scale detectors will be sensitive to several neutrino interaction channels, with thousands of events expected if a supernova emerges in the galaxy neighborhood. There is a limited number of tools to study the interaction rates of supernova neutrinos, although a plethora of available supernova models exists. EstrellaNueva is an open-source software to calculate expected rates of supernova neutrinos in detectors using target materials with typical compositions, and additional compositions can be easily added. This software considers the flavor transformation of neutrinos in the supernova through the adiabatic Mikheyev--Smirnov--Wolfenstein effect, and their interaction in detectors through several channels. Most of the interaction cross sections have been analytically implemented, such as neutrino-electron and neutrino-proton elastic scattering, inverse beta decay, and coherent elastic neutrino-nucleus scattering. This software provides a link between supernova simulations and the expected events in detectors by calculating fluences and event rates to ease any comparison between theory and observation. It provides a simple and standalone tool to explore many physics scenarios offering an option to add analytical cross sections and define any target material.

description: COVID_19 virus become unprecedented pandemic disease after WHO declared it globally since its outbreak. In Ethiopia, the first COVID-19 case was reported on March 13, 2020. To control the spread of coronavirus, Ethiopia had declared state of emergence since the inborn of COVID-19. Then, the established taskforce has implemented initial prevention and mitigation measures. Awareness creation campaign was undertaken through mass and screaming media by professional health workers. This study was aimed to identify the level of Community perception, challenges and prevention mechanisms of COVID-19 pandemic disease in Arsi Zone, Oromia Regional State. The study was undertaken from 05-18/05/2020. Research teams from college of social science and humanities, Arsi University has undertaken descriptive qualitative study using semi structured interview and participatory observation after purposefully identifying the existing campaigning sessions about COVID-19 virus. The study revealed that communities has positive perception about transmitting and prevention mechanism of COVID_19, but their attitudes and practices of applying recommended prevention mechanisms were inconsistent and irrelevant. Besides, established taskforces for COVID-19 to apply and supervise health emergency state. Therefore, though the campaign has contributed a lot in creating about awareness of COVID-19 transmitting and prevention mechanism, communities and taskforces were irresponsible to apply recommended measurements by WHO,EPHI and MoE. Accordingly, concerning bodies should have to recognize new campaign mechanisms and strictly supervise the implementations recommended prevention mechanisms by health emergence taskforces.
