Time efficient state-of-charge estimation using open circuit voltage and the logarithmic modelling for battery management system
Creators: name: Shen, Jing Cong
Publisher: name: University of British Columbia
Year: 2016

description: Battery management systems are important devices for protecting batteries in various electrical and electronic applications. One of the most important features of a properly designed battery management system is the diagnostic techniques for estimating the remaining usable charge in batteries in a time effective manner. This thesis presents two time-efficient and reliable techniques that do not require complex electronic hardware for application. One technique concerns the open-circuit voltage characteristics of a battery while the other technique considers the logarithmic modeling of the equivalent circuit of a lithium-ion battery so that the equilibrium OCV can be found within a shorter period of time. The logarithmic modelling method uses the equivalent circuit model and the characteristics of the subject lithium NMC battery and finds the equilibrium OCV. This thesis will include two techniques for the logarithmic modelling method. One technique uses the long time constant in the equivalent model of the battery and predicts the equilibrium with 1% error after the battery relaxes for 150 seconds. The other technique uses the short time constant in the equivalent model and predicts the equilibrium OCV with 2% error after the battery relaxes for 70 seconds. Both techniques of the logarithmic modeling method show improvement for estimating the equilibrium OCV in terms of waiting time compared to the standard methods.

description: We show that an electronic beam passing through the collisionless plasma of the "cold" ions and the "hot" Boltzmann electrons can give rise to the propagation of the supersonic ion-acoustic rarefaction shock waves. These waves are analogous to those predicted by Zeldovich [5] in gasodynamics and complementary to the ion-acoustic compression shock waves in collisionless plasma described by Sagdeev [3].

description: A mathematical model of the plant growth dynamics of based on a system of differential equations is constructed. A separate differential equation which describes the development of the subsystem and its connection with other subsystems is developed for each plant subsystem. The system of differential equations is solved by a numerical method. From the set of solutions of the system of differential equations, only those are selected for which the sum of the squares of the deviations from the experimental values is the smallest. The constructed mathematical model makes it possible to conduct simulation experiments and translate the results of field experiments into digital format.

description: We present a study of a large, statistically complete sample of star-forming dwarf galaxies using mid-infrared observations from the {\it Spitzer Space Telescope}. The relationships between metallicity, star formation rate (SFR) and mid-infrared color in these systems show that the galaxies span a wide range of properties. However, the galaxies do show a deficit of 8.0 \um\ polycyclic aromatic hydrocarbon emission as is apparent from the median 8.0 \um\ luminosity which is only 0.004 \lstarf\ while the median $B$-band luminosity is 0.05 \lstarb. Despite many of the galaxies being 8.0 \um\ deficient, there is about a factor of 4 more extremely red galaxies in the [3.6] $-$ [8.0] color than for a sample of normal galaxies with similar optical colors. We show correlations between the [3.6] $-$ [8.0] color and luminosity, metallicity, and to a lesser extent SFRs that were not evident in the original, smaller sample studied previously. The luminosity--metallicity relation has a flatter slope for dwarf galaxies as has been indicated by previous work. We also show a relationship between the 8.0 \um\ luminosity and the metallicity of the galaxy which is not expected given the competing effects (stellar mass, stellar population age, and the hardness of the radiation field) that influence the 8.0 \um\ emission. This larger sample plus a well-defined selection function also allows us to compute the 8.0 \um\ luminosity function and compare it with the one for the local galaxy population. Our results show that below 10$^{9}$ $L$\solar, nearly all the 8.0 \um\ luminosity density of the local universe arises from dwarf galaxies that exhibit strong \ha\ emission -- i.e., 8.0 \um\ and \ha\ selection identify similar galaxy populations despite the deficit of 8.0 \um\ emission observed in these dwarfs.

description: Enzyklopädische Handbücher fungieren in der Wissenschaft als wichtige Bestandsaufnahmen und Referenzpunkte für Forschung und Lehre – ihre Veröffentlichung im Open Access ist daher wünschenswert. Jedoch ist die Partizipation der Geistes-, Sozial- und Bildungswissenschaften an Open Access bisher noch vergleichsweise gering. Einerseits fehlen Kenntnisse zu und Erfahrungen mit dieser Publikationsform. Andererseits sind Open-Access-Bemühungen häufig am Paradigma der STM-Disziplinen (engl.: Science, Technologies, Medicine) orientiert, deren finanzielle Ausstattung eine andere ist und die vorwiegend Zeitschriftenartikel veröffentlichen (Graf/Fadeeva 2020, 15; https://doi.org/10.17185/duepublico/72237).
 Das vom BMBF geförderte Verbundprojekt „Open-Access-Publikation von enzyklopädischen Handbüchern – OAPEnz“ des Verlags Barbara Budrich und von ZB MED – Informationszentrum Lebenswissenschaften setzt an dieser Stelle an. Kern des Vorhabens ist die Herausgabe eines „lebendigen“ enzyklopädisch angelegten Handbuchs der Deutschen Vereinigung für Politikwissenschaft zum Thema „Politik und Geschlecht“, das sukzessive im Goldenen Open Access und zusätzlich in regelmäßigen Abständen als eBook mit Print-on-Demand-Option im Verlagsprogramm erscheinen wird.
 Am Ende des Projektes steht neben der Handbuchpublikation und der Entwicklung eines nachhaltigen Geschäftsmodells für ähnliche Publikationen auch die Weiterentwicklung der PUBLISSO-Publikationsplattform. Diese soll zu einer frei nutzbaren Lösung für kleine und mittlere sowie wissenschaftseigene Verlage werden, die sich an weitere in den Geistes- und Sozialwissenschaften gängige Publikationsformate anpassen lässt. Die Entwicklungen der PUBLISSO-Plattform werden nachhaltig im Open Source auch anderen Wissenschafts- und wissenschaftseigenen Verlagen zur Verfügung gestellt.
 Das Projekt macht innovative Open-Access-Publikationsformate auch für Disziplinen jenseits STM zugänglich. Durch die Zusammenarbeit von Verlag, herausgebender Fachgesellschaft und Infrastrukturanbieter kann auf Anforderungen aus der sozial- und geisteswissenschaftlichen Community gezielt eingegangen werden.

description: Aim. The investigation of peculiarities of winter rapeseed (Brassica napus L.) growing technology elements, such as sowing time and fertilization level, on yield and quality indexes of crop seeds. Methods. It was used the general scientific and special research methods: field method, balance-calculation method for the planned yield, taking into account the content of nutrients in the soil, visual, measurement-weight, biochemical method and mathematical, and statistical in the process of performing the work. Results. There was an improvement of biometric parameters for plant overwintering and plant condition at the time of spring vegetation renewal with increasing fertilizer rates, the most optimal ones were formed during the second sowing period on August 21 for all sowing dates. The highest yield was obtained on the second sowing period in the version with the maximum fertilization, it was 3.8 t / ha. The strongest correlation 0.827 was observed when comparing the yield with the mass of 1000 seeds, according to the coefficient of determination, the variation of the yield depended on the elements of the crop structure by 52.4-68.5%. The minimum acid value of 1.05 KOH / g was obtained for the second sowing period on August 21, with the maximum fertilizer variant; in general, the value of this indicator decreased with the increase of fertilizer rate; the content of glucosinolates increased with increasing rate of fertilizer; protein content was influenced by both the sowing period and the fertilizer level, the highest value of which was 22.65% achieved during the second sowing period with maximum fertilization. The highest oil content was also obtained with the introduction of N240P120K240 47.99%, but for the third sowing period on September 5. The content of erucic acid increased proportionally with the increase in the level of fertilizer, with no significant effect of the sowing period on this indicator. Conclusions. The results of the study indicate a significant influence of the sowing period, fertilizer system and biological features of the hybrid on the key moments of plant growth and development, the formation of their biometric parameters, yields and quality indicators, which is confirmed by the results of mathematical data processing

description: High contrast imaging at optical wavelengths is limited by the modest correction of conventional near-IR optimized AO systems.We take advantage of new fast and low-readout-noise detectors to explore the potential of fast imaging coupled to post-processing techniques to detect faint companions to stars at small separations. We have focused on I-band direct imaging of the previously detected brown dwarf binary HD130948BC,attempting to spatially resolve the L2+L2 benchmark system. We used the Lucky-Imaging instrument FastCam at the 2.5-m Nordic Telescope to obtain quasi diffraction-limited images of HD130948 with ~0.1" resolution.In order to improve the detectability of the faint binary in the vicinity of a bright (I=5.19 \pm 0.03) solar-type star,we implemented a post-processing technique based on wavelet transform filtering of the image which allows us to strongly enhance the presence of point-like sources in regions where the primary halo dominates. We detect for the first time the BD binary HD130948BC in the optical band I with a SNR~9 at 2.561"\pm 0.007" (46.5 AU) from HD130948A and confirm in two independent dataset that the object is real,as opposed to time-varying residual speckles.We do not resolve the binary, which can be explained by astrometric results posterior to our observations that predict a separation below the NOT resolution.We reach at this distance a contrast of dI = 11.30 \pm 0.11, and estimate a combined magnitude for this binary to I = 16.49 \pm 0.11 and a I-J colour 3.29 \pm 0.13. At 1", we reach a detectability 10.5 mag fainter than the primary after image post-processing. We obtain on-sky validation of a technique based on speckle imaging and wavelet-transform processing,which improves the high contrast capabilities of speckle imaging.The I-J colour measured for the BD companion is slightly bluer, but still consistent with what typically found for L2 dwarfs(~3.4-3.6).

description: We propose using a pre-trained segmentation model to perform diagnostic classification in order to achieve better generalization and interpretability, terming the technique reverse-transfer learning. We present an architecture to convert segmentation models to classification models. We compare and contrast dense vs sparse segmentation labeling and study its impact on diagnostic classification. We compare the performance of U-Net trained with dense and sparse labels to segment A-lines, B-lines, and Pleural lines on a custom dataset of lung ultrasound scans from 4 patients. Our experiments show that dense labels help reduce false positive detection. We study the classification capability of the dense and sparse trained U-Net and contrast it with a non-pretrained U-Net, to detect and differentiate COVID-19 and Pneumonia on a large ultrasound dataset of about 40k curvilinear and linear probe images. Our segmentation-based models perform better classification when using pretrained segmentation weights, with the dense-label pretrained U-Net performing the best.

Nitrification in Fixed Bed Reactors Treating Saline Wastewater

description: Two fixed bed reactors for nitrification with either polyethylene/clay sinter lamellas (FBR A) or porous ceramic rings (FBR B) were continously run for treating synthetic saline wastewater. Seawater from Hafen Büsum was used as an inoculums. The performance of the system was evaluated under different operating conditions. 
A better overall nitrification without nitrite accumulation was observed in FBR B during continuous incubation. However, in term of ammonia (AOR) and nitrite oxidation rates (NOR) that were determined in batch incubations, FBR A revealed a higher AOR and NOR of 6 and 7 mg N L-1 h-1, compared to the AOR and NOR of 5 and 5.9 mg N L-1 h-1 in FBR B, respectively. 
 For studies of the effect of fluctuating salinity on the nitrification, polyethylene/clay sinter lamellas or porous ceramic rings from FBR A and B, respectively, were used as a source of immobilized nitrifiers. Salt concentrations were decreased from 3.5% to 0.03% via 2, 1 and 0.5% and increased from 3.5% to 5, 7 and 9%.
 A similar result for AOR and NOR during batch incubation was obtained for both substrata in FBR A and FBR B. The salinity changes influenced more the nitrite oxidizing bacteria (NOB) than the ammonia oxidizing bacteria (AOB).
 Measurement of oxidation rates during changing conditions show that the NORs were always higher than the AORs in all reactors, especially in initial phase. However, NORs were more sensitive to the salinity fluctuation than AORs, especially at lower salinity. The AORs remained constant for 0.5-3.5% NaCl and dropped to 70% and 68.5% after the salt concentration was brought to 0.034 or 5%, respectively. The NORs decreased significantly to 62% and 87.5% of initial rates after the salt concentration was changed to 2 and 5%, respectively.
Non-halotolerant nitrifiers reactors with fresh polyethylene/clay as supporting material were inoculated with water samples taken from a "Brackwasser"-location at the North Sea and were continuously run. The salt content in medium was 0% at the start and was then increased up to 10.5%.
 Increases of the salt concentration in a non-salt-adapted FBR suppressed more to NOR than AOR. When salinity was increased from 0.03% to 0.5, 1 and 2%, AORs remained constant. The AORs were approx. 90% of initial rates after the salt concentrations were increased stepwise to 3.5%, whereas the NORs decreased to 85, 52 and 36% of initial rate after salinity was increased to 1, 2 and 3.5%, respectively.

description: We have carried out a near-infrared, narrow-band imaging survey of the Crab Nebula, in the H2 2.12 micron and Br-gamma 2.17 micron lines, using the Spartan Infrared camera on the SOAR Telescope. Over a 2.8' x 5.1' area that encompasses about 2/3 of the full visible extent of the Crab, we detect 55 knots that emit strongly in the H2 line. We catalog the observed properties of these knots. We show that they are in or next to the filaments that are seen in optical-passband emission lines. Comparison to HST [S II] and [O III] images shows that the H2 knots are strongly associated with compact regions of low-ionization gas. We also find evidence of many additional, fainter H2 features, both discrete knots and long streamers following gas that emits strongly in [S II]. A pixel-by-pixel analysis shows that about 6 percent of the Crab's projected surface area has significant H2 emission that correlates with [S II] emission. We measured radial velocities of the [S II] lambda6716 emission lines from 47 of the cataloged knots and find that most are on the far (receding) side of the nebula. We also detect Br-gamma emission. It is right at the limit of our survey, and our Br-gamma filter cuts off part of the expected velocity range. But clearly the Br-gamma emission has a quite different morphology than the H2 knots, following the long linear filaments that are seen in H-alpha and in [O III] optical emission lines.

description: This study proposes a versatile model for the dynamics of the best bid and ask prices using an extended Hawkes process. The model incorporates the zero intensities of the spread-narrowing processes at the minimum bid-ask spread, spread-dependent intensities, possible negative excitement, and nonnegative intensities. We apply the model to high-frequency best bid and ask price data from US stock markets. The empirical findings demonstrate a spread-narrowing tendency, excitations of the intensities caused by previous events, the impact of flash crashes, characteristic trends in fast trading over time, and the different features of market participants in the various exchanges.

description: We present a simple mathematical criterion for determining whether a given statistical model does not describe several independent sets of measurements, or data modes, adequately. We derive this criterion for two data sets and generalise it to several sets by using the Bayesian updating of the posterior probability density. To demonstrate the usage of the criterion, we apply it to observations of exoplanet host stars by re-analysing the radial velocities of HD 217107, Gliese 581, and \u{psion} Andromedae and show that the currently used models are not necessarily adequate in describing the properties of these measurements. We show that while the two data sets of Gliese 581 can be modelled reasonably well, the noise model of HD 217107 needs to be revised. We also reveal some biases in the radial velocities of \u{psion} Andromedae and report updated orbital parameters for the recently proposed 4-planet model. Because of the generality of our criterion, no assumptions are needed on the nature of the measurements, models, or model parameters. The method we propose can be applied to any astronomical problems, as well as outside the field of astronomy, because it is a simple consequence of the Bayes' rule of conditional probabilities.

description: We use a complete sample of Lya emission-line selected AGNs obtained from nine deep blank fields observed with the grism spectrographs on the Galaxy Evolution Explorer (GALEX) satellite to measure the normalization and spectral shape of the AGN contribution to the ionizing background (rest-frame wavelengths 700-900 A) at z~1. Our sample consists of 139 sources selected in the redshift range z=0.65-1.25 in the near-ultraviolet (NUV; 2371 A central wavelength) channel. The area covered is 8.2 square degrees to a NUV magnitude of 20.5 (AB) and 0.92 square degrees at the faintest magnitude limit of 21.8. The GALEX AGN luminosity function agrees well with those obtained using optical and X-ray AGN samples, and the measured redshift evolution of the ionizing volume emissivity is similar to that previously obtained by measuring the GALEX far-ultraviolet (FUV; 1528 A central wavelength) magnitudes of an X-ray selected sample. For the first time we are able to construct the shape of the ionizing background at z~1 in a fully self-consistent way.

Subjects: subject: Human-Computer Interaction (cs.HC)

description: The possibility for humans to interact with physical or virtual systems using gestures has been vastly explored by researchers and designers in the last twenty years to provide new and intuitive interaction modalities. Unfortunately, the literature about gestural interaction is not homogeneous, and it is characterised by a lack of shared terminology. This leads to fragmented results and makes it difficult for research activities to build on top of state-of-the-art results and approaches. The analysis in this paper aims at creating a common conceptual design framework to enforce development efforts in gesture-based human-machine interaction. The main contributions of the paper can be summarised as follows: (i) we provide a broad definition for the notion of functional gesture in human-machine interaction, (ii) we design a flexible and expandable gesture taxonomy, and (iii) we put forward a detailed problem statement for gesture-based human-machine interaction. Finally, to support our main contribution, the paper presents, and analyses 83 most pertinent articles classified on the basis of our taxonomy and problem statement.

description: For many protocols, quantum strategies have advantages compared with their classical counter-partners, and these advantages have attracted many interests and applications. One of the famous examples is the Clauser-Horne-Shimony-Holt (CHSH) game, which recasts Bell's theorem~\cite{2} into the framework of a game. In the CHSH game, two space-like separated players, Alice and Bob are each assigned a classical bit $a$ and $b$ respectively. Then they return bits $x$ and $y$ according to some pre-agreed strategies. They will win the game when $x\oplus y= a\cdot b$. In the game, if the players use the classical strategies, the optimal success probability $w(\text{CHSH})=0.75$.However, if they add some quantum resources, the success probability will increase and up to maximal value $cos^2(π/8)$, which is know as the Tsirelson's bound. Moreover, Popescu and Rohrlich noted that the perfect success probability $1$ can also be achieved in a more general theory without violating the no-signaling assumption

description: We find the orbit of the Neptune-sized exoplanet HAT-P-11b to be highly inclined relative to the equatorial plane of its host star. This conclusion is based on spectroscopic observations of two transits, which allowed the Rossiter-McLaughlin effect to be detected with an amplitude of 1.5 m/s. The sky-projected obliquity is 103_{-10}^{+26} degrees. This is the smallest exoplanet for which spin-orbit alignment has been measured. The result favors a migration scenario involving few-body interactions followed by tidal dissipation. This finding also conforms with the pattern that the systems with the weakest tidal interactions have the widest spread in obliquities. We predict that the high obliquity of HAT-P-11 will be manifest in transit light curves from the Kepler spacecraft: starspot-crossing anomalies will recur at most once per stellar rotation period, rather than once per orbital period as they would for a well-aligned system.

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

description: Hypothetical color-octet particles of spin 0, pair-produced at hadron colliders through their QCD coupling, may lead to final states involving three or four b jets. We analyze kinematic distributions of the 3b final state that differentiate the scalar octets from supersymmetric Higgs bosons. Studying the scalar sector that breaks an SU(3) \times SU(3) gauge symmetry down to the QCD gauge group, we find that the scalar octet is resonantly produced in pairs via a spin-1 octet (coloron). A scalar octet of mass in the 140 - 150 GeV range can explain the nonstandard shape of the b-jet transverse energy distributions reported by the CDF Collaboration, especially when the coloron mass is slightly above twice the scalar mass. The dominant decay mode of the scalar octet is into a pair of gluons, so that the production of a pair of dijet resonances is large in this model, of about 40 pb at the Tevatron. Even when a W boson is radiated from the initial state, the inclusive cross section for producing a dijet resonance near the scalar octet mass remains sizable, around 0.15 pb.

A study tour of the Rwandan genocide : an exploration of personal and professional learning for teachers
Creators: name: Holly, Ryan Mark
Publisher: name: University of British Columbia
Year: 2016

description: Many teachers look to study tours as professional development opportunities for a variety of topics. In July of 2014 teachers from across Canada travelled to Rwanda on a study tour organized by Genocide Education Canada to commemorate the twentieth anniversary of the Rwandan Genocide. This study examines the personal motivations that caused teachers to want to participate in this study tour, and how the teachers were impacted both personally and professionally by the trip. The study is supported by experiential learning, travel-based education, and study tour theory. Ten teachers were interviewed, and their responses were analyzed qualitatively using grounded theory, from the constructivist epistemological framework, and the theoretical perspective of interpretivism. The researcher also participated in the study tour, and acknowledges the personal values of travel and education, global citizenship theory, and parenthood and children, and discusses how these values could impact the research. This study shows that teachers were both personally and professionally motivated to participate in the study tour for various reasons. Teachers believed that the study tour was a valuable learning experience, and were confident in the knowledge that they acquired. Teachers described episodes of uncomfortable learning, and were able to apply their learning to their homes. Teachers returned with a sense of obligation to share what they had learned, and they believed that they learned a great deal from simply being in a different country. Teachers believed that the study tour impacted their lives both personally and professionally, but were also cognizant that they would have enjoyed more free time while on the trip. The findings of this study are discussed in light of what they mean for teachers, for professional development, and for instructional and curriculum planning for student learning. Furthermore, notions of reciprocity are explored, and what study tours could mean for people of the host country.

Integrating fluorescence visualization with clinical markers to predict oral cancer recurrences
Creators: name: Wu, King Yin Marco
Publisher: name: University of British Columbia
Year: 2016

description: One reason for the poor survival rate of oral cancer is the high rate of recurrence (REC). The objective of this study is to investigate how fluorescence visualization (FV) may play in the prediction of oral cancer REC at a site previously treated for oral cancer. We will confirm previously identified clinical factors for REC such as lesion presence and TB status, and analyze if any combinations of these three factors at varying follow-up time intervals can suggest a higher risk for REC. Information for this study will come from patients enrolled in the BC Oral Cancer Prediction Longitudinal study. Patients are eligible if: 1) they had a primary tumour diagnosis of SCC or CIS; 2) were treated with curative intent; and 3) had at least one recall visit within one year after completion of initial treatment. Data analyzed: 1) demographic and lifestyle habit information; 2) primary tumour information; 3) oral clinicopathological features during follow-up at 6, 12, 18, and 24 months. For this thesis, 232 patients have been identified that fit the inclusion criteria. Of those, 34 patients developed recurrence, and 198 patients remained tumour free throughout their follow-up period. Demographic, smoking, alcohol and FV status were not found to be associated with a recurrence. Of significance, OPL status at all follow-up intervals (P<0.01), TB at 6, 12, 24 months (P<0.05), and TBFV at 6 and 12 months (P<0.05) were associated with REC. There is a higher percentage of REC in patients with TB+FV+ status than other combinations of TBFV status, with significance found at 6 and 12 months follow-up post-treatment. With known risk factors for predicting REC, clinicians can recognize patients at increased risk, improving the chance of early detection. This can also drive clinician decision-making for patients deemed high-risk, increasing surveillance and improving patient care.

description: In recent years a very exciting and intense activity has been devoted to the understanding and construction of materials that enjoy exotic optical properties, such as a negative refractive index. Motivated by these experimental and theoretical developments, we use the string-inspired idea of holography to study the electromagnetic response of a certain class of media: strongly coupled relativistic systems that admit a dual gravitational description. Our results indicate that this type of media generally have a negative refractive index. Moreover we observe that a negative refractive index could be a common feature of relativistic hydrodynamic systems at low frequencies.

description: We present a catalog of photometrically variable stars discovered within two 21'.3 X 21'.3 fields centered on the Cygnus OB2 association. There have hitherto been no deep optical variability studies of Cyg OB2 despite it being replete with early-type massive stars, perhaps due to the high and variable extinction (up to A_V ~ 20) that permeates much of the region. Here we provide results of the first variability study with this combination of spatial coverage (~ 0.5 deg) and photometric depth (R ~ 21 mag). We find 121 stars to be variable in both R- and I-band, 116 of them newly discovered. Of the 121 variables, we identify 27 eclipsing binaries (EBs) and eclipsing binary candidates, 20 potential Herbig Ae/Be stars, and 52 pulsating variables. Confirming both the status and the cluster membership of the Herbig Ae/Be stars would address the uncertainty regarding the age and star formation history of Cyg OB2. We match our catalog to known variables and binaries in the region, 2MASS near-IR (NIR) data, and Chandra X-ray observations to find counterparts to new variables in other wavelengths.

Hund's coupling key role in multi-orbital correlations
Creators: name: Medici, Luca de'
Publisher: name: arXiv
Year: 2010
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We show how in multi-band materials, the Hund's coupling plays a crucial role in tuning the degree of electronic correlation. While in half-filled systems it enhances the correlations, in all other cases it pushes the boundary for the Mott transition at very high critical couplings. Moreover in weakly-hybridized non-degenerate systems the Hund's coupling plays the role of band-decoupler, causing a change from a collective to an individual band behavior, due to the freezing of orbital fluctuations. In this situation the physics is strongly dependent on individual filling and electronic structure of each band, and orbital-selective Mott transitions (or even a cascade of such transitions) are to be expected. More generally a heavy differentiation in the actual degree of correlation of different bands arises and the system can show both weakly and strongly correlated electrons.
STUDENT SUCCESS FRAMEWORKS IN US COMMUNITY COLLEGES

description: The article considers the student success frameworks in community colleges in the United States of America. Success as a broad category can have several meanings, but it is always associated with a positive result. The student success determines the effectiveness of community colleges, so finding ways to improve the educational process is an actual problem of higher education in the United States. Since the beginning of the XXI century, American educators have been developing the student success frameworks. The Lumina Foundation initiative aims to use research data on students' problems in achieving success and implementing a “culture of evidence” in the work of colleges. Based on the obtained data, educators develop intervention strategies to improve student performance, identify barriers to academic progress, and disseminate positive experiences in developing effective programs. The Ellucian initiative is another interesting example of the implementation of reforms in the work of community colleges. The strategy proposed by the specialists contains six steps and begins with creating a common vision of student success, focusing on the actions of successful students and defining a strategy for early intervention in the problem of failure. From the smallest steps of assessing and improving the situation and establishing links with all structures, it is possible to overcome the problem of existing obstacles to student success, using the data obtained in the most rational way. The article contains an overview of scientific works that are the result of long-term research and can be a useful experience for Ukrainian higher education institutions.
On the time variability of the star formation efficiency

description: A star formation efficiency per free fall time that evolves over the life time of giant molecular clouds (GMCs) may have important implications for models of supersonic turbulence in molecular clouds or for the relation between star formation rate and H2 surface density. We discuss observational data that could be interpreted as evidence of such a time variability. In particular, we investigate a recent claim based on measurements of H2 and stellar masses in individual GMCs. We show that this claim depends crucially on the assumption that H2 masses do not evolve over the life times of GMCs. We exemplify our findings with a simple toy model that uses a constant star formation efficiency and, yet, is able to explain the observational data.

description: This study investigates ways in which students can improve their conceptual understanding of complex biological processes. A model of protein synthesis from the Web-based learning environment Cell World was studied by 59 French students. Students had to manipulate certain virtual molecules so that they would react as a biological phenomenon. Questions on a worksheet investigated student understanding of the ontological categories of objects and processes under the influence of the manipulable and non-manipulable model components. The results of the study suggest a trend wherein the category of processes was less understood than those of objects.

description: Real world datasets often contain noisy labels, and learning from such datasets using standard classification approaches may not produce the desired performance. In this paper, we propose a Gaussian Mixture Discriminant Analysis (GMDA) with noisy label for each class. We introduce flipping probability and class probability and use EM algorithms to solve the discriminant problem with label noise. We also provide the detail proofs of convergence. Experimental results on synthetic and real-world datasets show that the proposed approach notably outperforms other four state-of-art methods.
