description: We check the recently proposed higher loop Bethe-ansatz for the sl(2) sector of N=4 at two loops by a direct perturbative calculation using N=2 superfields in supersymmetric dimensional reduction. Our method can in principle address operators built from many elementary fields and of arbitrary twist. We work out in detail the spin three, twist three operator mixing problem at leading order in N and find agreement with the prediction based on integrability.

description: We study the effects of HD molecules on thermochemical evolution of the primordial gas behind shock waves, possibly arised in the process of galaxy formation. We find the critical shock velocity when deuterium transforms efficiently into HD molecules which then dominate gas cooling. Above this velocity the shocked gas is able to cool down to the temperature of the cosmic microwave background. Under these conditions the corresponding Jeans mass depends only on redshift and initial density of baryons $M_J \propto δ_c^{-0.5} (1+z)^{0.5}$. At $z\simgt 45$ HD molecules heat shocked gas, and at larger redshift their contribution to thermal evolution becomes negligible.

description: In this paper, a new method to efficiently simulate diffusion controlled second order chemical reactions is derived and applied to site-specific DNA-binding proteins. The protein enters a spherical cell and propagates via two competing modes, a free diffusion and a DNA-sliding mode, to search for its specific binding site in the center of the cell. There is no need for a straightforward simulation of this process. Instead, an alternative and exact approach is shown to be essentially faster than explicit random-walk simulations. The speed-up of this novel simulation technique is rapidly growing with system size.

description: We describe a newly-discovered detached M-dwarf eclipsing binary system, the fourth such system known. This system was first observed by the TrES network during a long term photometry campaign of 54 nights. Analysis of the folded light curve indicates two very similar components orbiting each other with a period of 1.12079 +/- 0.00001 days. Spectroscopic observations with the Hobby-Eberly Telescope show the system to consist of two M3e dwarfs in a near-circular orbit. Double-line radial velocity amplitudes, combined with the orbital inclination derived from light-curve fitting, yield Mass total = 0.983 +/- 0.007 solar masses, with component masses M(1) = 0.493 +/- 0.003 and M(2) = 0.489 +/- 0.003 solar masses. The light-curve fit yields component radii of R(1) = 0.453 +/- 0.060 and R(2) = 0.452 +/- 0.050 solar radii. Though a precise parallax is lacking, broadband VJHK colors and spectral typing suggest component absolute magnitudes of M_V(1) = 11.18 +/- 0.30 and M_V(2) = 11.28 +/- 0.30.

We identified in the (F435W-F625W, F435W) plane more than two thousand White Dwarf (WD) candidates using three out of nine available pointings. Such a large sample appears in agreement with predictions based on the ratio between WD and Horizontal Branch (HB) evolutionary lifetimes. We also detected ~ 1600 WDs in the (F658N-F625W, F625W) plane, supporting the evidence that a large fraction of current cluster WDs are $H_α$ bright.

description: The loss of biodiversity is considered one of the most serious threats of modern age. The vast majority of species facing extinction belongs to insufficiently studied invertebrate taxa. Loss of species causes loss of functional diversity and affects ecosystem services, often with consequences for human well-being. More specifically, the loss of pollinator species can lead to a decrease in the productivity of many crops, thus affecting not only the global biodiversity, but also economy.
 In our study, we focus on hoverflies, Dipteran family being considered the second-most significant group of pollinators after bees. Here we used two different approaches, obtaining information from air and from ground, in order to assess different parameters that might have influence on the diversity of Syrphids. UAV (Unmanned Aerial Vehicle) photogrammetry and image processing were used to acquire landscape parameters. As for the information on soil composition, both chemical and granulometric analysis were conducted.
 The application of combined modern analyses might help in revealing the factors influencing the biodiversity of this important pollinator group, which would remain hidden if only traditional methods were used. This type of results could contribute in determining the threatening factors not only for hoverflies, but for biodiversity in general, thus attributing in alleviating the negative consequences on ecosystem functioning.

description: The Axion Resonant InterAction DetectioN Experiment (ARIADNE) will search for spin-dependent forces mediated by the QCD axion between an unpolarized Tungsten source mass and a sample of polarized helium-3 as the sensor by using a nuclear magnetic resonance based technique. The experiment relies on low magnetic gradients for the helium to remain polarized during transport to the sample cell, limiting ordinary magnetic noise with superconducting magnetic shielding as well as a stable rotary system to modulate the axion-signal from the source mass. Background and current progress on the experiment will be discussed.
An engineered biosynthetic hydrogel for 3D neural tissue interfaces

Publisher: name: Imperial College London
Year: 2023

description: Bionic implants are widely used to replace or restore impaired neurological functions. However, they normally rely on stiff metallic electrodes, which can trigger inflammatory responses hindering long-term device performance. Although different material and form factor design strategies have been explored, the establishment of a chronically stable device-tissue interface remains challenging. It has been proposed that tissue-engineered coatings composed of hydrogel matrices embedded with neural cells could enhance the biointegration and hence long-term performance of implantable electrodes. Furthermore, establishing synaptic connectivity between the implant and the host tissue would enable novel and more biomimetic mechanisms of tissue neuromodulation. However, the lack of biomaterials able to support the development of functional neural networks hinders the implementation of these 'living electrode' constructs. This thesis aimed to design a biosynthetic hydrogel carrier with key physicochemical cues to guide the development of primary neuroprogenitor cells into functional neural networks. To investigate the influence of cell-material interactions in neural development, neuroprogenitor cells were encapsulated in hydrolytically degradable poly(vinyl alcohol) (PVA) hydrogels functionalised with low amounts (10%) of sericin and gelatin (PVA-SG). The results indicated that the limited biological content and the restrictive polymer network impaired the growth of encapsulated astrocytes, which in turn hindered neural development. Therefore, an enzymatically degradable PVA-gelatin hydrogel (PVA-GEL) with tuneable mechanospatial properties was developed. By systematically varying the gelatin content from 0 to 100%, it was found that only hydrogels with greater than 50% gelatin could promote the growth of encapsulated primary mature astrocytes while maintaining mechanical stability. Furthermore, neuroprogenitor cells co-encapsulated with mature astrocytes in PVA-GEL hydrogels were able to grow into synaptically active neural networks. Finally, PVA-GEL hydrogels were shown to interface with and support the ingrowth of brain tissue ex vivo, highlighting their potential in the design of biointegrative electrode coatings for more efficacious and longer-lasting bionic devices.

description: This dissertation aims to show the extent of the interpreters being affected by their jurisprudential doctrines and defining the most important explanatory jurisprudential writings and its courses. Then, there will be display of models through the verses of the provisions in Surat Al-Nur. This dissertation includes an entry and three chapters: the first one will show the most important explanatory jurisprudential writings and its courses. The second is to view defining Surah Al-Nur, and its Contents.The third chapter is to view the terms and doctrinal issues that were being debated in Surat Al-Nur and the commentators' attitudes of them and how they are affected by their doctrines. The most important results is that the effect of religious jurisprudence was positive rather than a negative one, where the religious jurisprudence urges the commentator to sharpen the idea to expand the deduction, and keep track of minutes doctrinal issues, objectively and impartially, it was a sign of the verse in favor of the doctrine taken, otherwise it is likely to say the strongest evidence, which contributed to open writings in comparative jurisprudence research production, perhaps equal to books written in this field. Being fanatic to the doctrine of jurisprudence in the books of interpretation has been very limited, and the highlight was when Jassas and Kia Herasy, however, they were defending their doctrines through long discussions and extensive other doctrines, which has helped to enrich the heritage of Islamic Fiqh. As demonstrated by the research is the importance of doctrinal interpretations that are not related with the judgments verses only, just like the interpretations of Almathhary , Al-Alusi , Alqurtuby and Al-Razi. The jurisprudence article which may equal or exceed the books devoted to the interpretation of the judgments verses.

description: Rheological properties of a material often require to be probed under extensional deformation. Examples include fibrous materials such as spider-silk, high-molecular weight polymer melts, and the contractile response of living cells. Such materials have strong molecular-level anisotropies which are either inherent or are induced by an imposed extension. However, unlike shear rheology, which is well-established, techniques to perform extensional rheology are currently under development and setups are often custom-designed for the problem under study. In this article, we present a versatile device that can be used to conduct extensional deformation studies of samples at microscopic scales with simultaneous imaging. We discuss the operational features of this device and present a number of applications.

description: Motivation: Cryo-Electron Tomography (cryo-ET) visualizes structure and spatial organization of macromolecules and their interactions with other subcellular components inside single cells in the close-to-native state at sub-molecular resolution. Such information is critical for the accurate understanding of cellular processes. However, subtomogram classification remains one of the major challenges for the systematic recognition and recovery of the macromolecule structures in cryo-ET because of imaging limits and data quantity. Recently, deep learning has significantly improved the throughput and accuracy of large-scale subtomogram classification. However often it is difficult to get enough high-quality annotated subtomogram data for supervised training due to the enormous expense of labeling. To tackle this problem, it is beneficial to utilize another already annotated dataset to assist the training process. However, due to the discrepancy of image intensity distribution between source domain and target domain, the model trained on subtomograms in source domainmay perform poorly in predicting subtomogram classes in the target domain. Results: In this paper, we adapt a few shot domain adaptation method for deep learning based cross-domain subtomogram classification. The essential idea of our method consists of two parts: 1) take full advantage of the distribution of plentiful unlabeled target domain data, and 2) exploit the correlation between the whole source domain dataset and few labeled target domain data. Experiments conducted on simulated and real datasets show that our method achieves significant improvement on cross domain subtomogram classification compared with baseline methods.

Year: 2009

description: In this study the researcher sought to understand the language skills required by English as a Second Language students in a Resident Care Attendant (RCA) Program in order to discover a language basis on which the RCA curriculum might be further developed. In order to discover the language being used to learn the RCA course content, a combination of research methods applicable to studying second language classrooms was adopted: classroom observation and interviewing both faculty and students. This naturalistic, qualitative case study also used methods from the field of ethnography in order to analyze the data. Using methodology of grounded theory resulted in the emergence of categories that very closely resembled language functions used across curricula. Further analysis also indicated a number of learner strategies and social contexts that impacted upon the language learner. Finally, recommendations for future research and curriculum building and teaching were made.

description: Crackling noise is a common feature in many dynamic systems [1-9], the most familiar instance of which is the sound made by a sheet of paper when crumpled into a ball. Although seemingly random, this noise contains fundamental information about the properties of the system in which it occurs. One potential source of such information lies in the asymmetric shape of noise pulses emitted by a diverse range of noisy systems [8-12], but the cause of this asymmetry has lacked explanation [1]. Here we show that the leftward asymmetry observed in the Barkhausen effect [2] - the noise generated by the jerky motion of domain walls as they interact with impurities in a soft magnet - is a direct consequence of a magnetic domain wall's negative effective mass. As well as providing a means of determining domain wall effective mass from a magnet's Barkhausen noise our work suggests an inertial explanation for the origin of avalanche asymmetries in crackling noise phenomena more generally.

description: Random Al and Ag nanoparticle distributions are studied on varying substrates, where we exploit the nanosphere self-aggregation method (NSA) for fabrication. Relying on the measured particle size distributions of these samples, we develop a theoretical model that can be applied to arbitrary random nanostructure layers as is demonstrated for several distinct NSA samples. As a proof of concept, the optical properties of the exact same particles distributions, made from the quasi random modeling input with electron beam lithography (EBL), are investigated from both theory and experiment. Our numerical procedure is based on rigorous solutions of Maxwell's equations and yields optical spectra of fully interacting randomly positioned nanoparticle arrays. These results constitute a new methodology for improving the optical performance of layers of nanoparticles with direct application to enhanced photovoltaics.

description: In the last decade, creativity has increasingly become one of the most wanted skills of the 21st century that students in higher education need in order to achieve success in the information age. Creative individuals establish a powerful aspect of facing complex changes and challenges in different sources of competition (Kilgour, 2006). As a result, researchers started to focus on the understanding of creativity. Hence, new and valid creativity assessment researches are required to help measure creativity and identify creative individuals in higher education. Creativity assessment is the cornerstone of active creativity development in higher education. In particular, it provides a reliable and valid measure of a students’ learning and knowledge; it also guides the institutions, teachers, and students on a consistent basis. The measurement of creativity is one of the main topics in creativity research; creativity is one of the most challenging skill to measure in any of the 21st century skills (The World Economic Forum, 2016). We argue that, in additions to the big five, creativity in higher education is related to the environment and that more research is needed to understand these relations. The search for reliable and valid instruments to measure this construct has been the most challenging subject confronting creativity researchers.

description: Point defects in body-centred cubic Fe, Cr and concentrated random magnetic Fe-Cr are investigated using density functional theory and theory of elasticity. The volume of a substitutional Cr atom in ferromagnetic bcc Fe is approximately 18\% larger than the volume of a host Fe atom, whereas the volume of a substitutional Fe atom in antiferromagnetic bcc Cr is 5\% smaller than the volume of a host Cr atom. Elastic dipole $\boldsymbol{P}$ and relaxation volume $\boldsymbolΩ$ tensors of vacancies and self-interstitial atom (SIA) defects exhibit large fluctuations, with vacancies having negative and SIA large positive relaxation volumes. Dipole tensors of vacancies are nearly isotropic across the entire alloy composition range, with diagonal elements $P_{ii}$ decreasing as a function of Cr content. Fe-Fe and Fe-Cr SIA dumbbells are more anisotropic than Cr-Cr dumbbells. Fluctuations of elastic dipole tensors of SIA defects are primarily associated with the variable crystallographic orientations of the dumbbells. Statistical properties of tensors $\boldsymbol{P}$ and $\boldsymbolΩ$ are analysed using their principal invariants, suggesting that point defects differ significantly in alloys containing below and above 10\% at. Cr. The relaxation volume of a vacancy depends sensitively on whether it occupies a Fe or a Cr lattice site. A correlation between elastic relaxation volumes and magnetic moments of defects found in this study suggests that magnetism is a significant factor influencing elastic fields of defects in Fe-Cr alloys.

description: Spitzer photometry and spectroscopy of the star HD69830 reveal an excess of emission relative to the stellar photosphere between 8 and 35 $μ$m dominated by strong features attributable to crystalline silicates with an emitting surface area more than 1,000 times that of our zodiacal cloud. The spectrum closely resembles that of the comet C/1995 O1 (Hale-Bopp). Since no excess is detected at 70 $μ$m, the emitting material must be quite warm, be confined within a few AU of the star, and originate in grains with low long-wavelength emissivity, i.e. grains much smaller than $70 μ$m$/2π\sim 10 $ $μ$m. The strong mineralogical features are evidence for even smaller, possibly sub-micron sized grains. This small grain size is in direct contrast to the 10-100 $μ$m grains that dominate the relatively featureless spectra of our zodiacal dust cloud and most other main sequence stars with excesses. The upper limit at 70 $μ$m also implies that any Kuiper Belt analog must either be very cold or be less massive than $\sim$ 5 times our own Kuiper Belt. With collisional and Poynting-Robertson drag times of about a thousand years for small grains, the emitting material must either: a) be created through continual grinding down of material in a dense asteroid belt; or b) originate in cometary debris arising from either a single ``super-comet'' or a very large number of individual comets arriving from a distant reservoir. In the case of a cometary origin for the emission, the mass requirements for continuous generation by many individual comets are unreasonable and we favor the capture of a single ``super comet'' into a 0.5-1 AU orbit where it can evolve a large number of small grains over a 2 Myr period.

description: Nowadays teaching requires peculiar styles, techniques and approximation that every teacher should have. There have been so many changes in educational system and societies all over the world and it influences on teaching children perceptibly. Therefore, teachers have to fill a lot of roles in order to make an effective classroom. They are people with educational leadership skills and they must go on growing and developing as professionals. Anyone seeking to be a teacher should take advantage of any chance they get to grow as a person and as a teacher. The article highlights the roles of teachers in today’s world.
Negotiating participation in second language academic communities : subtitle a study of identity, agency, and transformation
Creators: name: Morita, Naoko
Publisher: name: University of British Columbia

description: As the student population grows increasingly diverse and international in North American postsecondary institutions, it has become critical, on the one hand, to understand how newcomers from different backgrounds acquire academic discourses in their second language (L2), and on the other hand, how academic communities as well as individual learners may respond to this heterogeneity. This study explores these issues by providing a close examination of the lived experiences and perspectives of L2 international students enrolled in graduate courses at a Canadian university. The participants in this ethnographic multiple case study included six female graduate students from Japan and ten of their course instructors. Data were collected over an entire academic year mainly by means of student self-reports, interviews, and classroom observations. Grounded in the notion of "community of practice" (Lave & Wenger, 1991; Wenger, 1998), this study analyzes how the focal students negotiated their membership in their new classroom communities by participating in classroom discussions. The findings suggested that a major challenge faced by the students was negotiating discourses, competence, identities, and power relations in order to participate and be recognized as legitimate and competent members of their classroom communities. The students also attempted to shape their own learning and participation by exercising their personal agency and actively negotiating their positionalities, which were locally constructed in a given classroom. Notably, even though the students shared a similar linguistic/cultural background as well as the same gender, there was considerable variability among them in the ways they negotiated their participation and experienced personal transformations across different courses. By demonstrating the idiosyncratic, complex interplay between the individual learner and the classroom context, I argue that academic discourse socialization needs to be seen as a co-constructed and negotiated process, through which the learner's identity as well as the classroom community is constantly created and recreated. I also suggest that educators can work toward emancipatory classroom practices by recognizing the fundamentally dialogic and transformative nature of classroom practices and by critically examining the roles and positionalities that are constructed of different participants in university courses.
Gluonic phase in neutral two-flavor dense QCD

description: In the Ginzburg-Landau approach, we describe a new phase in neutral two-flavor quark matter in which gluonic degrees of freedom play a crucial role. We call it a gluonic phase. In this phase gluonic dynamics cure a chromomagnetic instability in the 2SC solution and lead to spontaneous breakdown of the color gauge symmetry, the electromagnetic U(1), and the rotational SO(3). In other words, the gluonic phase describes an anisotropic medium in which the color and electric superconductivities coexist. Because most of the initial symmetries in this system are spontaneously broken, its dynamics is very rich.

description: During the last decade, the relation between activity cycle periods with stellar parameters has received special attention. The construction of reliable registries of activity reveals that solar type stars exhibit activity cycles with periods from few years to decades and, in same cases, long and short activity cycles coexist suggesting that two dynamos could operate in these stars. In particular, Epsilon Eridani is an active young K2V star (0.8 Gyr), which exhibits a short and long-term chromospheric cycles of near 3 and 13-yr periods. Additionally, between 1985 and 1992, the star went through a broad activity minimum, similar to the solar Maunder Minimum-state. Motivated by these results, we found in Epsilon Eridani a great opportunity to test the dynamo theory. Based on the model developed in Sraibman & Minotti (2019), in this work we built a non linear axisymmetric dynamo for Epsilon Eridani. The time series of the simulated magnetic field components near the surface integrated in all the stellar disc exhibits both the long and short-activity cycles with periods similar to the ones detected from observations and also time intervals of low activity which could be associated to the broad Minimun. The short activity cycle associated to the magnetic reversal could be explained by the differential rotation, while the long cycle is associated to the meridional mass flows induced by the Lorentz force. In this way, we show that a single non-linear dynamo model derived from first principles with accurate stellar parameters could reproduce coexisting activity cycles.

description: We observe that the Rector invariants classifying the genus of BS^3 show up in (orthogonal and unitary) K-theory. We then use this knowledge to show purely algebraically how the K-theory of the spaces in the genus of BS^3 differ. This provides new insights into a result of Notbohm in the case of BS^3.

description: Increased availability of scanner-based panel data has enabled researchers to better understand nondurable commodity purchase dynamics. In this study, we focus on one component of the purchase process--when to buy. The relationship between the discrete purchase decision and a set of household and purchase characteristics is quantified using a simulated maximum-likelihood procedure. Given the longitudinal nature of our data, unobserved heterogeneity is addressed by adopting an auto-correlated error structure. Our empirical application is household purchases of cheese. We find evidence of significant persistent unobservable household heterogeneity, which is not eliminated by the inclusion of lagged exogenous variables.

description: Application of the tobit model to estimate economic welfare is transferred from the consumer side to the producer side. Supply functions are estimated for multioutput irrigators in the Pacific Northwest. Empirical procedures are then developed for computing expected producer's surplus from the output supply functions. Confidence intervals for the surplus measures are generated using the Krinsky-Robb method. An experiment predicts decreases in surplus given increases in water pumping cost. The experiment replicates possible increases in hydroelectric prices due to the salmon recovery program in the Columbia-Snake River Basin. Output substitution explains producers' ability to mitigate the effect of the price increases on producer's surplus.

description: The agricultural value of El Nino-Southern Oscillation (ENSO) phase knowledge is measured in a value-of-information framework using economic models. We examine the value of considering the full distribution of ENSO phase strength effects as opposed to average ENSO phase strength effects, as well as the implications of considering ENSO impacts on the rest of the world (ROW). A stochastic U.S. agricultural sector model linked with a global trade model is used to assess the value of ENSO phase information. When the full distribution of ENSO phase strength is considered, the value of phase information increases twofold with respect to the average ENSO effects.

description: The effect of Tennessee Valley Authority reservoir water levels on recreational fishing is evaluated. Data were collected in east Tennessee during March through August of 1994-97. Water levels were not a major barrier to participation during the six-month period, but levels did affect the number of trips taken by anglers. Maintaining lakes at full pool for one additional summer month would result in an additional one-third trip per angler, or an additional 87,000 trips in the study region. The average net benefit of a full pool is $1.82 per angler, or an aggregate benefit of approximately $476,500 in the region.

description: We present a high-resolution computer simulation study of the equation of state of ST2 water, evaluating the liquid-state properties at 2718 state points, and precisely locating the liquid-liquid critical point (LLCP) occurring in this model. We are thereby able to reveal the interconnected set of density anomalies, spinodal instabilities and response function extrema that occur in the vicinity of a LLCP for the case of a realistic, off-lattice model of a liquid with local tetrahedral order. In particular, we unambiguously identify a density minimum in the liquid state, define its relationship to other anomalies, and show that it arises due to the approach of the liquid structure to a defect-free random tetrahedral network of hydrogen bonds.

description: Following a generic approach that leads to Bogomolny-Prasad-Sommerfield (BPS) soliton solutions by imposing self-duality, we investigate three different types of non-Hermitian field theories. We consider a complex version of a logarithmic potential that possess BPS super-exponential kink and antikink solutions and two different types of complex generalisations of systems of coupled sine-Gordon models with kink and antikink solution of complex versions of arctan type. Despite the fact that all soliton solutions obtainedin this manner are complex in the non-Hermitian theories we show that they possess real energies. For the complex extended sine-Gordon model we establish explicitly that the energies are the same as those in an equivalent pair of a non-Hermitian and Hermitian theory obtained from a pseudo-Hermitian approach by means of a Dyson map. We argue that the reality of the energy is due to the topological properties of the complex BPS solutions. These properties result in general from modified versions of antilinear CPT symmetries that relate self-dual and an anti-self-dual theories.
