description: ExbB and ExbD are cytoplasmic membrane proteins that associate with TonB to convey the energy of the proton-motive force to outer membrane receptors in Gram-negative bacteria for iron uptake. The opportunistic pathogen Serratia marcescens (Sm) possesses both TonB and a heme-specific TonB paralog, HasB. ExbBSm has a long periplasmic extension absent in other bacteria such as E. coli (Ec). Long ExbB's are found in several genera of Alphaproteobacteria, most often in correlation with a hasB gene. We investigated specificity determinants of ExbBSm and HasB. We determined the cryo-EM structures of ExbBSm and of the ExbB-ExbDSm complex from S. marcescens. ExbBSm alone is a stable pentamer, and its complex includes two ExbD monomers. We showed that ExbBSm extension interacts with HasB and is involved in heme acquisition and we identified key residues in the membrane domain of ExbBSm and ExbBEc, essential for function and likely involved in the interaction with TonB/HasB. Our results shed light on the class of inner membrane energy machinery formed by ExbB, ExbD and HasB.

description: We propose a Berry phase effect on the chiral degrees of freedom of a triangular magnetic molecule. The phase is induced by adiabatically varying an external electric field in the plane of the molecule via a spin-electric coupling mechanism present in these frustrated magnetic molecules. The Berry phase effect depends on spin-orbit interaction splitting and on the electric dipole moment. By varying the amplitude of the applied electric field, the Berry phase difference between the two spin states can take any arbitrary value between zero and $π$, which can be measured as a phase shift between the two chiral states by using spin-echo techniques. Our result can be used to realize an electric field induced geometric phase-shift gate acting on a chiral qubit encoded in the ground state manifold of the triangular magnetic molecule.

description: On-farm precision experimentation (OFPE) has expanded rapidly over the past years. While the importance of efficient trial designs in OFPE has been recognized, the design efficiency has not been assessed from the economic perspective. This study reports how to use Monte Carlo simulations of corn-to-nitrogen (N) response OFPEs to compare economic performances of thirteen different OFPE trial designs. The economic performance is measured by the profit from implementing the N “prescription” (i.e., estimated site-specific economically optimal N rates) provided by analysing the OFPE data generated by a trial design. Results showed that the choice of trial design affects the final economic performance of OFPE. Overall, the best design was the Latin square design with a special pattern of limited N rate “jump” (LJ), which had the highest average profit and lowest profit variation in almost all simulation scenarios. The economic performance of the high efficiency fixed-block strip design (SF1) was only slightly lower than that of LJ, and could be a good alternative when only strip designs are available. In contrast, designs with gradual trial rate changes over space were less profitable in most situations, and should be avoided. Those results were robust to various nitrogen-to-corn price ratios, yield response estimation models, and field sizes used in the simulations. It was also found that the statistical efficiency measures of trial designs roughly explained the designs’ economic performances, though there are still much part remaining unexplained.

description: We study spinless fermions with nearest-neighbor repulsive interactions ($t$-$V$ model) on the two-dimensional three-band Lieb lattice. At half-filling, the free electronic band structure consists of a flat band at zero energy and a single cone with linear dispersion. The flat band is expected to be unstable upon inclusion of electronic correlations, and a natural channel is charge order. However, due to the three-orbital unit cell, commensurate charge order implies an imbalance of electron and hole densities and therefore doping away from half-filling. Our numerical results show that below a finite-temperature Ising transition a charge density wave with one electron and two holes per unit cell and its partner under particle-hole transformation are spontaneously generated. Our calculations are based on recent advances in auxiliary-field and continuous-time quantum Monte Carlo simulations that allow sign-free simulations of spinless fermions at half-filling. It is argued that particle-hole symmetry breaking provides a route to access levels of finite doping, without introducing a sign problem.

description: Background: Gram-positive bacteria are common causes of both community acquired and nosocomial infections. This is compounded by the development of multi-drug resistance in this group of bacteria. The aim of this study is to characterize and evaluate drug susceptibility profile of Gram-positive cocci isolated from different clinical samples in the study area. Objective: The main objective of this study was to determine the prevalence of gram positive cocci and multidrug resistance pattern of Gram positive cocci isolated from different clinical samples. Methods: A laboratory based cross-sectional study was conducted to determine the prevalence of multidrug resistant strains of Gram-positive bacteria isolated from 792 patients referred to Arsho Advanced Medical Laboratory, from January to April 2018.Different clinical samples were collected and inoculated onto primary isolation culture media, blood culture bottles and blood agar. Preliminary identification was carried on based on number, type, morphology appearance of colonies and Gram reaction after growth on culture media. Identification and drug susceptibility testing also carried out by GP and AST-GP71 cards of the VITEK 2 compact systems. Result: A total of 792 patients were participated on the study. The mean (std. deviation) ages of patients was 34.8 (20.2).The overall prevalence of gram positive cocci were 12.6 % (n=100/792) of which the most frequent one is S. aureus 54% (n=54/100) followed by CoNs 42% (n=42/100), S.agalactiae 1% (n=1/100) and E.faecalis3 % (n=3/100). The overall prevalence of multi drug resistant gram positive cocci (resistant for≥ two different classes of antibiotics) was (75%).Penicillin showed the highest resistance rate (85%), followed by Sulphamethazole /trimethoprim (47%), and Oxacillin (38%) for gram positive cocci bacteria. Conclusion: High antimicrobial resistance and Multi drug resistance were demonstrated over the Study period, such as Penicillin was the most resistant followed by trimethoprim/ sulfamethoxazole and oxacillin. To prevent further emergence and spread of MDR bacterial pathogens, rational use of antibiotics and regular monitoring of antimicrobial resistance patterns are essential and mandatory.

description: The AUC margin loss is a valuable loss function for medical image classification as it addresses the problems of imbalanced and noisy labels. It is used by the current winner of the CheXpert competition. The CheXpert dataset is a large dataset (200k+ images), however datasets in the range of 1k-10k medical datasets are much more common. This raises the question if optimizing AUC margin loss also is effective in scenarios with limited data.We compare AUC margin loss optimization to binary cross-entropy on limited, imbalanced and noisy CheXpert5000, a subset of CheXpert dataset. We show that AUC margin loss is beneficial for limited data and considerably improves accuracy in the presence of label noise. It also improves out-of-box calibration.

description: The detection of long-lived radionuclides through ultra-sensitive single atom counting via accelerator mass spectrometry (AMS) offers opportunities for precise measurements of neutron capture cross sections, e.g. for nuclear astrophysics. The technique represents a truly complementary approach, completely independent of previous experimental methods. The potential of this technique is highlighted at the example of the $^{54}$Fe($n, γ$)$^{55}$Fe reaction. Following a series of irradiations with neutrons from cold and thermal to keV energies, the produced long-lived $^{55}$Fe nuclei ($t_{1/2}=2.744(9)$ yr) were analyzed at the Vienna Environmental Research Accelerator (VERA). A reproducibility of about 1% could be achieved for the detection of $^{55}$Fe, yielding cross section uncertainties of less than 3%. Thus, the new data can serve as anchor points to time-of-flight experiments. We report significantly improved neutron capture cross sections at thermal energy ($σ_{th}=2.30\pm0.07$ b) as well as for a quasi-Maxwellian spectrum of $kT=25$ keV ($σ=30.3\pm1.2$ mb) and for $E_n=481\pm53$ keV ($σ= 6.01\pm0.23$ mb). The new experimental cross sections have been used to deduce improved Maxwellian average cross sections in the temperature regime of the common $s$-process scenarios. The astrophysical impact is discussed using stellar models for low-mass AGB stars.

description: During the COVID-19 pandemic, questions have been raised about the impact of face masks on communication in classroom settings. However, it is unclear to what extent visual obstruction of the speaker's mouth or changes to the acoustic signal lead to speech processing difficulties, and whether these effects can be mitigated by semantic predictability, i.e., the availability of contextual information. The present study investigated the acoustic and visual effects of face masks on speech intelligibility and processing speed under varying semantic predictability. Twenty-six children (aged 8-12) and twenty-six adults performed an internet-based cued shadowing task, in which they had to repeat aloud the last word of sentences presented in audio-visual format. The results showed that children and adults made more mistakes and responded more slowly when listening to face mask speech compared to speech produced without a face mask. Adults were only significantly affected by face mask speech when both the acoustic and the visual signal were degraded. While acoustic mask effects were similar for children, removal of visual speech cues through the face mask affected children to a lesser degree. However, high semantic predictability reduced audio-visual mask effects, leading to full compensation of the acoustically degraded mask speech in the adult group. Even though children did not fully compensate for face mask speech with high semantic predictability, overall, they still profited from semantic cues in all conditions. Therefore, in classroom settings, strategies that increase contextual information such as building on students' prior knowledge, using keywords, and providing visual aids, are likely to help overcome any adverse face mask effects.

Publisher: name: University of Alberta Library
Year: 2022

In this paper, a piezoelectric energy harvester with a grounded and tunable multi-stable nonlinear energy sink (NES) has been developed to achieve vibration suppression (VS) and energy harvesting (EH) simultaneously. The NES consists of a cantilever beam whose free end is attached by a small magnet and a movable holder containing two magnets. And the three magnets face a stationary magnet on the base whose height can be manually adjusted. The mono-stable NES (MNES), bi-stable NES (BNES) and tri-stable NES (TNES) can be achieved by moving the holder along the beam or raising or lowering the stationary magnet manually. The electromechanical model of the system is derived from the lumped parameter model, and the magnetic force model is deduced based on the magnetic dipole approach. Next, a series of simulations are conducted to investigate the VS and EH performance of the systems with the  grounded MNES, BNES and TNES under the low and high- level impact excitation. The simulation results depict that the  systems with the MNES and BNES will have a better performance in VS when the excitation level is low and high, respectively, and the system with the MNES outperforms in EH among the three systems for both low and high excitation levels.

description: Efficient induction of target-specific antibodies can be elicited upon immunization with highly immunogenic virus-like particles (VLPs) decorated with desired membrane-anchored target antigens (Ags). However, for example, for diagnostic purposes, monoclonal antibodies (mAbs) are required to enable the histological examination of formaldehyde-fixed paraffin-embedded (FFPE) biopsy tissue samples. Aiming at the generation of FFPE-antigen-specific mAbs and as a proof of concept (POC), we first established a simplified protocol using only formaldehyde and 90 °C heat fixation (FF90) of cells expressing the target Ag nerve growth factor receptor (NGFR). The FF90 procedure was validated using flow cytometric analysis and two mAbs recognizing either the native and FFPE-Ag or exclusively the native Ag. C-terminally truncated NGFR (trNGFR)-displaying native and FF90-treated VLPs derived from HIV-1 did not reveal distinctive changes in particle morphology using transmission electron microscopy (TEM) and dynamic light scattering (DLS) analysis. Mice were subsequently repetitively immunized with trNGFR-decorated FF90-VLPs and hybridoma technology was used to establish mAb-producing cell clones. In multiple screening rounds, nine cell clones were identified producing mAbs distinctively recognizing epitopes in FF90- and FFPE-NGFR. This POC of a new methodology should foster the future generation of mAbs selectively targeting FFPE-fixed cell-surface Ags.

description: There are phenomena present in our environment that can't be fully assessed effectively using human numerical calculations. One of those phenomena is fluid dynamics. Software-based simulation is used to thoroughly assess the dynamics related to fluid flowing through a pipe and heat transfer during the operation. Here, the simulation program COMSOL Multiphysics 3.5a was utilized to analyze this occurrence. In this study, the finite element approach is primarily employed to analyze the thermal and hydrodynamic profiles produced by the laminar flow of air and water through a pipe. For the scenario outlined, changes in performance metrics throughout the pipe are also evaluated in an isoflux state.

description: Background: Onychomycosis is among the most frequent forms of human infections; being estimated to affect more than 20-25% in worldwide, and their incidence is constantly increasing particularly in developing countries. Although onychomycosis is considered to be a trivial disease the psychological effects of onychomycosis is highly considerable and because of its high morbidity it is a costly disease in terms of loss of working days and treatment. Anyone can get a fungal nail infection. Some people may be more likely than others to get a fungal nail infection, including older adults and people who have nail injury or nail surgery, Diabetes and a weakened immune system and blood circulation problems. Objective: - To determine the prevalence of onychomycosis and profile fungal etiologic agents collected from clinical suspected samples in All African TB and Leprosy Rehabilitation Training Center. Methods: -a cross sectional study design from January to May, 2018 was conducted. A total of 303 study participants were collected by convenient sampling techniques. By using standard structured questionnaire socio-demographic data was collected and fungal pathogen from scraped nail sample was isolate and identified by using KOH microscopic examination and cultivation on sabouroud and chromo agar. Data was analyzed using SPSS version 23 software and P- value < 0.05 was considered as statically significant. Results:-The overall prevalence is of onychomycosis185/303(61.3 %) in our study site. Non Dermatophytes was the most prevalent (34.5%), followed by dermatophytes (28.1%), yeast (25.9%) and mixed (10%). fungal pathogen .Aspergillus was the most common species (spp) isolated among the non dermatophytes, whereas t.tonsurans and t.mentagrophyte spp were among the dermatophytes and from yeast genes Candida albican were isolated. Conclusion: The prevalence and profile of fungal onychomycosis infections seems to be related to age, life style, and the presence of co-morbidities (P= 0.03). The present study indicated that non dermatophytes were the main agents causing onychomycosis. In the meantime performing direct examination and fungal culture was important to diagnoseand treat the patients. Predisposing factors have a contribution to increase the incidence of onychomycosis.

description: We study the occurrence of negative differential conductance induced by resonance effects in a model for a multilayer heterostructure. In particular, we consider a system consisting of several correlated and non-correlated monoatomic layers, sandwiched between two metallic leads. The geometry confines electrons in wells within the heterostructures, which are connected to each other and to the leads by tunneling processes. The non-equilibrium situation is produced by applying a bias-voltage to the leads. Our results show that for specific values of the parameters resonance tunneling takes place. We investigate in detail its influence on the current-voltage characteristics. Our results are obtained via non-equilibrium real-space dynamical mean-field theory. As an impurity solver we use the so-called auxiliary master equation approach, which addresses the impurity problem within an auxiliary system consisting of a correlated impurity, a small number of uncorrelated bath sites, and two Markovian environments described by a generalized master equation.

description: Multivariate pattern analysis (MVPA) or brain decoding methods have become standard practice in analysing fMRI data. Although decoding methods have been extensively applied in Brain Computing Interfaces (BCI), these methods have only recently been applied to time-series neuroimaging data such as MEG and EEG to address experimental questions in Cognitive Neuroscience. In a tutorial-style review, we describe a broad set of options to inform future time-series decoding studies from a Cognitive Neuroscience perspective. Using example MEG data, we illustrate the effects that different options in the decoding analysis pipeline can have on experimental results where the aim is to 'decode' different perceptual stimuli or cognitive states over time from dynamic brain activation patterns. We show that decisions made at both preprocessing (e.g., dimensionality reduction, subsampling, trial averaging) and decoding (e.g., classifier selection, cross-validation design) stages of the analysis can significantly affect the results. In addition to standard decoding, we describe extensions to MVPA for time-varying neuroimaging data including representational similarity analysis, temporal generalisation, and the interpretation of classifier weight maps. Finally, we outline important caveats in the design and interpretation of time-series decoding experiments.

Year: 2016

description: Background: Water Quality monitoring is assessed widely using different indicators. Since there is no universal indicator that has been identified yet, assessing water quality using bacterial and viral indicators that would provide a more complete picture of water quality. Objective: To assess the quality of drinking water using bacterial and cophages indicators. Methodology: A cross sectional prospective study was conducted on 218 drinking water samples of various sources collected from some regions of Ethiopia from February to June 2016 to determine coliphages by the help of CB390 E. coli host using plaque assay technique; most probable number for coliforms and pouring for hetrotrophic plate count at Ethiopian Public Health Institute. The data was analyzed using SPSS 20 statistical package. Results: Hetrophilic bacteria, total and thermotolerant coliforms, E. coli and coliphages were detected in 72.9 %, 51.8%, 38.5%, 23.9% and 2.3 % of total water samples respectively. HPC > 1.0x102 Cfu/ml were noted in 41 (18.8%) water samples and detections of total coliforms, thermotolerant coliforms and E. coli in 38 (17.4%), 24 (11.0%) and 10 (4.6%) samples respectively and no detection of phages in chlorinated waters. While, HPC > 1.0x102 Cfu/ml were observed in 100 (45.9%) water samples and detections of total and thermotolerant coliforms, E.coli and coliphages in 75 (34.4%), 60 (27.5%), 42 (19.3% ) and 5 (2.3%) samples respectively for the untreated waters. Rho values between total coliphages and other indicators, HPC, total coliforms, thermotolerant coliforms were 0.202, 0.232 and 0.269 respectively. Total heterophilic plate count, total coliforms, thermotolerant coliforms, E.coli and total coliphages were statistically differed by region; sources and treatment type (P value < 0.05). Coliphages were not detected in all waters except rivers. Conclusion: Majority of the waters, mainly untreated sources contained bacterial and viral indicators above the standard limits. This indicates that the sources are contaminated with environmental and fecal contaminants signifying poor quality of water and it is a potential threat for human health. Hence regular monitoring of water source using coliphages and other bacterial indicators should be a priority agenda by all stake holders.

description: Cet article explore l’usage de Facebook comme outil de communication externe pour les entreprises commerciales. A travers une étude descriptive portant sur trois entreprises à savoir SOLIBRA, la Société Ivoirienne de Banque (SIB) et Orange CI, il a été question d’examiner l’utilisation de Facebook. En Côte d’Ivoire, Facebook est l’un des réseaux sociaux les plus populaires, offrant à ces entreprises un puissant levier pour interagir avec leurs publics cibles. Ainsi, l’hégémonie de Facebook les a poussées à se digitaliser davantage, à renforcer leur présence en ligne et à adapter leurs stratégies de communication et de marketing. Néanmoins, elles rencontrent des limites spécifiques liées à l'utilisation de cette plateforme dans leur communication externe. Ces limites, bien qu’universelles, prennent une coloration particulière dans le contexte ivoirien. Une utilisation optimale de cette plateforme nécessite une stratégie de contenu adaptée, une gestion active de la réputation et une diversification vers d'autres canaux de communication.
A New Statistic Feature of the Short-Time Amplitude Spectrum Values for Human's Unvoiced Pronunciation

description: In this paper, a new statistic feature of the discrete short-time amplitude spectrum is discovered by experiments for the signals of unvoiced pronunciation. For the random-varying short-time spectrum, this feature reveals the relationship between the amplitude's average and its standard for every frequency component. On the other hand, the association between the amplitude distributions for different frequency components is also studied. A new model representing such association is inspired by the normalized histogram of amplitude. By mathematical analysis, the new statistic feature discovered is proved to be necessary evidence which supports the proposed model, and also can be direct evidence for the widely used hypothesis of "identical distribution of amplitude for all frequencies".

description: Floating point error is an inevitable drawback of embedded systems implementation. Computing rigorous upper bounds of roundoff errors is absolutely necessary to the validation of critical software. This problem is even more challenging when addressing non-linear programs. In this paper, we propose and compare two new methods based on Bernstein expansions and sparse Krivine-Stengle representations, adapted from the field of the global optimization to compute upper bounds of roundoff errors for programs implementing polynomial functions. We release two related software package FPBern and FPKiSten, and compare them with state of the art tools. We show that these two methods achieve competitive performance, while computing accurate upper bounds by comparison with other tools.

description: Background: Intestinal parasites are one of the most neglected but the most wide spread and major public health problems in resource poor countries like Ethiopia. Studies have shown that intestinal parasites are prevalent among prison inmates. The lack of prompt and definitive laboratory method to diagnose intestinal parasitic infection is also one of the major problems in the control of the disease. Objective: The aim of this study was to determine the prevalence of intestinal parasitic species using different diagnostic approaches among diarrhogenic patients in prison inmates. Methods: A cross-sectional study was conducted from February to June 2017 in Addis Ababa Qilinto prison. A total of 335patients who were willing to participate, had diarrhea and not taken treatment had been included in the present study. Stool samples were collected from each study participant in clean stool collection cup and intestinal parasites were detected using wet mount, modified Zeihl_Nelsen staining and Auramine O stain. The data were double entered into excel file, cleaned, and analyzed using SPSS version 20.0. The prevalence of intestinal parasites was presented by using proportions. The difference between parasitological tests was compared using Pearson chi-square test. Results: From the total 335 study participants 185 (55.2%) came from urban area. About 90(26.9 %) of the prisoners had no formal education. The outcome of direct microscopic examination of stool sample showed that infections with various intestinal parasitic species were common in the study subjects. About 134(40%) prisoners were found positive for one or more of the intestinal parasites. E. histolytic, Gardia lamblia, Taenia species were the most common parasites detected in the prison, 56(16.7%), 15(4.5%), and 18(5.4%) respectively. Conclusion: The prevalence of Intestinal parasitic infection is the major public health problem in Qilinto prison, Addis Ababa, Ethiopia. Regular screening of prison inmates for intestinal parasites and potentially deworming strategy is a potential intervention that has to be considered by the concerned bodies.

The recovery of waste heat from low-temperature flue gas can be improved by capturing the latent heat part through the condensation of the vapor component. For this purpose, investigating the important parameters in designing efficient heat exchangers is necessary. Therefore, this study aims to develop a reliable model for simulating condensation heat transfer to help understand the involved phenomena and optimize the low-temperature waste heat recovery systems.  The studied flue gas was a mixture of multicomponent non-condensable gas and water vapor released by electric  generators or furnaces. In this study, mini-channel heat exchangers were explored in order to maximize heat transfer surface area and minimize heat exchanger size. A CFD model in Ansys Fluent was developed to analyze the condensation heat transfer in a mini-channel. Model accuracy was confirmed by comparison with experimental data available in the literature. Using the model, we then investigated the temperature field, vapor concentration, heat flux, and film thickness along the channel at inlet velocities ranging from 0.5 to 10 m/s (i.e., the corresponding Reynolds numbers of 31 to 617). The model has been found to be a powerful tool for predicting condensation heat transfer in the flue gas and designing heat exchangers for latent heat recovery.

Conformal Symmetry Breaking and Thermodynamics of Near-Extremal Black Holes

description: It has been argued recently by Almheiri and Polchinski that the near-horizon conformal symmetry of extremal black holes must be broken due to gravitational backreaction at an IR scale linear in $G_N$. In this paper, we show that this scale coincides with the so-called `thermodynamic mass gap' of near-extremal black holes, a scale which signals the breakdown of their thermodynamic description. We also develop a method which extends the analysis of Almheiri and Polchinski to more complicated models with extremal throats by studying the bulk linearized quantum field theory. Moreover, we show how their original model correctly captures the universal physics of the near-horizon region of near-extremal black holes at tree level, and conclude that this equivalence of the conformal breaking and mass gap scale is general.

Year: 2018

description: Background: Abnormal thyroid function test results are one of the common complications among HIV infected patients. Although the prevalence of overt thyroid disease does not appear to be significantly increased in HIV-infected patients, compared with the general population, specific patterns of abnormal thyroid function test findings are more frequently identified among HIV-infected patients. Objective: To assess thyroid dysfunction rate and associated factors among HAART taking pa-tients Methods: A hospital based cross sectional study was conducted from December 2017 to May 2018 at Bethel Teaching General Hospital, Addis Ababa, Ethiopia. A total of 300 HIV patients were enrolled in the study. Participants' socio-demographic and clinical information was collected from hospital cards. Serum and EDTA whole blood was examined for Thyroid function tests and CD4+ T cell count levels, respectively. Descriptive statistics was used to express the socio demographic characteristics. Binary and multiple logistic regressions were computed to assess association be-tween variables using SPSS version 20. Odds ratio with confidence interval and P<0.05 have been be used to determine strength and statistically significant differences. Results: Of the 300 individuals, 70 (23.3%) were identified with abnormal thyroid function, of whom, 47 (15.7%) were female and 23 (7.7%) male. 14(4.7%) were diagnosed with hyperthyroid-ism and 56(18.7%) with hypothyroidism. Of these, 35(62.5%) had subclinical hypothyroidism, 21 (37.5 %) had overt hypothyroidism. Out of these subclinical hypothyroid 23 (65.7%) were female and 12 (34.3 %) were males. The thyroid hormone levels however, did not correlate with duration of HAART and HIV duration. The levels of TSH, T3, T4 230(76.7%), 235(78.3%), 272(90.7%) for the majority of the participants were in the normal label respectively. There was a slight nega-tive correlation of CD4 counts with serum TSH levels (r =-0.1224 with p < 0.034) Conclusion: High rate of thyroid function test abnormalities was observed in HAART receiving HIV/AIDS individuals. Subclinical hypothyroidism was the most common disorder and females were more exposed, warranting thyroid function tests monitoring.

description: MaX organized an impressive set of education and training activities. This deliverable is a detailed report, including links to the programs and data on users’ participation and involvement. In D6.1 we proposed our structured “Education and Training plan”, aimed at bridging the skills gap between HPC development and computational materials science. In D6.3 we reported about the activities carried out in the first 18 months. Now we are reporting about the last 18 months (M19-M36). All the activities forecasted in the plan have been implemented. The main actions include: a. 12 training initiatives --schools, tutorials, workshops-- directly designed, organized and co-funded by MaX (sometimes in cooperation with others). The emphasis was on hands-on-activities based on MaX flagship codes and frontier HPC developments, and on the involvement of young participants. The overall assessment of these initiatives by the participants (approx. 350 in total) was extremely positive. b. A few lectures/modules offered by MaX within schools organized by other institutions. c. Major contributions to innovative education pilots within three University MSci courses. d. 23 ‘training through research’ visits in MaX laboratories. These initiatives have resulted in the production of valuable training material handed out to students. Some of the training material prepared for these events is available to the broader community as it has been published in the training section of the MaX website. Most partners have been heavily involved in the activities: Juelich, CNR, SISSA, ICN2, EPFL, CINECA, BSC, ETH Zürich, and UNESCO. Importantly, a significant number of activities have combined synergic contributions from different MaX partners with complementary expertise. Finally, MaX is maintaining an online repository of training initiatives of interest to the computational materials research community, which is useful to potential participants and also helps organizers in coordinating, identifying needs and avoiding overlaps.
