description: We provide a comprehensive survey of splitting and composition methods for the numerical integration of ordinary differential equations (ODEs). Splitting methods constitute an appropriate choice when the vector field associated with the ODE can be decomposed into several pieces and each of them is integrable. This class of integrators are explicit, simple to implement and preserve structural properties of the system. In consequence, they are specially useful in geometric numerical integration. In addition, the numerical solution obtained by splitting schemes can be seen as the exact solution to a perturbed system of ODEs possessing the same geometric properties as the original system. This backward error interpretation has direct implications for the qualitative behavior of the numerical solution as well as for the error propagation along time. Closely connected with splitting integrators are composition methods. We analyze the order conditions required by a method to achieve a given order and summarize the different families of schemes one can find in the literature. Finally, we illustrate the main features of splitting and composition methods on several numerical examples arising from applications.

description: The growing popularity of computer-mediated communication (CMC) has given rise to virtually endless possibilitiesfor second language (L2) teaching and learning. For one,computer-mediated tasks allow learners to work at their own pace,whilemaintaining the anonymityof the interlocutor(s).Such anonymityin turn lowerslearners’ anxietylevel(s)and arouses their interestinparticipation,resulting in a higher level of learner autonomy(Bhatia& Ritchie, 2009).A case in point would be computer-mediated instructionof L2writingusing Wikis. More specifically,multiple participants can edit a piece of writingand leave comments outside of the second language (L2)classroom; instead, learners write extensively via such media as blogs. This has shown (e.g., Nonaka, 2011; Sato, 2008) to have a positive effect on increasing the learner’s level motivation.

CMC and Face-to-face Communication in L2 Learning
Creators: name: Liu, Zehua
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: Bhatia and Richie (2009), in their book chapter, compare computer-mediated communication (CMC) and face-to-face communication by analyzing how learners behave when they learn a language in these two modes. Studies on face-to-face communication (e.g., VanPatten, 1990) reveal that learners have a tendency to process meaning before form because human interaction is conducted in real time. Speakers have to attend to the form (i.e., the oral output) and the meaning of the verbal production simultaneously. Previous studies on working memory (Li, 1999; Maehara and Saito, 2007) reveal that there is a trade-off between the maintenance and processing of information, as both involve working memory. VanPatten (2004), in particular, pinpoints that processing second language (L2) input involves making form-meaning connections in real-time comprehension, an online task that takes place in the working memory. As such, L2 learners have less memory space to store new information in face-to-face communication, given that the working memory is used for processing input. In contrast, CMC is said to provide more opportunities for focus on form.

description: We study the Deffuant et al. model for continuous--opinion dynamics under the influence of noise. In the original version of this model, individuals meet in random pairwise encounters after which they compromise or not depending of a confidence parameter. Free will is introduced in the form of noisy perturbations: individuals are given the opportunity to change their opinion, with a given probability, to a randomly selected opinion inside the whole opinion space. We derive the master equation of this process. One of the main effects of noise is to induce an order-disorder transition. In the disordered state the opinion distribution tends to be uniform, while for the ordered state a set of well defined opinion groups are formed, although with some opinion spread inside them. Using a linear stability analysis we can derive approximate conditions for the transition between opinion groups and the disordered state. The master equation analysis is compared with direct Monte-Carlo simulations. We find that the master equation and the Monte-Carlo simulations do not always agree due to finite-size induced fluctuations that we analyze in some detail.
Aligning CALL with the Theory and Practice of Instructed SLA
Creators: name: Lew, Adrienne Wai Man
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: With the availability of a wide range of information technologies in the 21st century, the second language (L2) classroom has by and large been transformed digitally. Such technological tools include, but are not limited to, authoring software and blogs, learning management systems (LMSs), online real-time texting via instant messengers (IMs) like Google Talk, audio-and video-conferencing through Skype, artificial intelligence (AI) and intelligent systems, speech recognition and pronunciation training technologies, mobile technologies, and even web-based social networking interfaces like Facebook and Google Plus. In a sense, computer-assisted language learning (CALL) seems to have brought about abundant opportunities for innovation and creativity vis-à-vis the language acquisition process. In order to fully capitalize from this technology craze, therefore, it is essential that the properties and strengths of these technologies be thoroughly studied in ways that would bring their applications in spirit with the core theoretical underpinnings and principles of practice in instructed second language acquisition (SLA) and its related research.

description: The evaluation of material networks is a relatively resource-intensive process in the rendering pipeline. Modern production scenes can contain hundreds or thousands of complex materials with massive networks, so there is a great demand for an efficient way of handling material networks. In this paper, we introduce an efficient method for progressively caching the material nodes without an overhead on the rendering performance. We evaluate the material networks as usual in the rendering process. Then, the output value of part of the network is stored in a cache and can be used in the evaluation of the next materials. Using our method, we can render the scene with performance equal to or better than that of the method without caching, with a slight difference in the images rendered with caching and without it.
CALL in the L2 Classroom: Possibilities and Limitations
Creators: name: Combs, Charles C.
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: The number of possibilities that computers and computer-assisted technology have opened up for second language (L2) learners over the years is intriguing. However, one must bear in mind that even though computer-assisted language learning (CALL) does create situations for computer-mediated interaction, can it really replace face-to-face interaction or just be an alternative resource? In larger numbers, with shrinking budgets, many universities are formulating online options for students in which one professor lectures to thousands of students online, and graduate assistants grade their assignments. While such an approach may be suitable for some content areas such as an Introduction to Psychology course, I think it could have different effects (though perhaps limited ones) in an L2 classroom, simply because face-to-face interaction is so vital. So in relating CALL to the existing body of interaction research in SLA, one question stands out: Will CALL provide the same opportunities for learners as face-to-face interaction?

description: Technology has revolutionized not only our daily lives but also the way education is practiced around the world. The impact of technology has been far and wide both in physical and social sciences, as well as in arts and humanities. This immense influence has been observed in second language (L2) teaching, acquisition, and research. In L2 instruction, for example, technological tools are used by: (1) practitioners for pedagogical advances; (2) learners for classroom and self- learning; (3) researchers for exploring the effects of technology on language teaching and learning (Bhatia & Ritchie, 2009). Although the use of technology to assist L2 acquisition has been under investigation for the past few decades, there is still much to be explored. Apparently, more research on the role(s) of technology in L2 teaching, learning, and research is needed to gain a better and more nuanced understanding.

description: We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140 GeV measured by VERITAS is well described by a power law with a photon index of 3.8 +- 0.5_stat +- 0.3_syst and a flux normalization at 200 GeV of (5.1 +- 0.9_stat +- 0.5_syst) x 10^{-11} TeV^-1 cm^-2 s^-1, where stat and syst denote the statistical and systematical uncertainty, respectively. The VHE flux is steady over the observation period between MJD 54881 and 55003 (2009 February 19 to June 21). Flux variability is also not observed in contemporaneous high energy observations with the Fermi Large Area Telescope (LAT). Contemporaneous X-ray and optical data were also obtained from the Swift XRT and MDM observatory, respectively. The broadband spectral energy distribution (SED) is well described by a one-zone synchrotron self-Compton (SSC) model favoring a redshift of less than 0.1. Using the photon index measured with Fermi in combination with recent extragalactic background light (EBL) absorption models it can be concluded from the VERITAS data that the redshift of PKS 1424+240 is less than 0.66.

description: The mid-IR spectra of six large, irregular PAHs with formulae (C84H24 - C120H36) have been computed using Density Functional Theory (DFT). Trends in the dominant band positions and intensities are compared to those of large, compact PAHs as a function of geometry, size and charge. Irregular edge moieties that are common in terrestrial PAHs, such as bay regions and rings with quartet hydrogens, are shown to be uncommon in astronomical PAHs. As for all PAHs comprised solely of C and H reported to date, mid-IR emission from irregular PAHs fails to produce a strong CCstr band at 6.2 um, the position characteristic of the important, class A astronomical PAH spectra. Earlier studies showed inclusion of nitrogen within a PAH shifts this to 6.2 um for PAH cations. Here we show this band shifts to 6.3 um in nitrogenated PAH anions, close to the position of the CC stretch in class B astronomical PAH spectra. Thus nitrogenated PAHs may be important in all sources and the peak position of the CC stretch near 6.2 um appears to directly reflect the PAH cation to anion ratio. Large irregular PAHs exhibit features at 7.8 um but lack them near 8.6 um. Hence, the 7.7 um astronomical feature is produced by a mixture of small and large PAHs while the 8.6 um band can only be produced by large compact PAHs. As with the CCstr, the position and profile of these bands reflect the PAH cation to anion ratio.

Microanalyzing Discourse in the Second and Foreign Language Classrooms: A Review of the Literature
Creators: name: Box, Catherine
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: Classroom interaction has long been a rich site for scholarly research, as attested by the sizable body of literature surrounding classroom discourse. This paper reviews three frameworks currently informing the analysis of classroom talk, or more specifically, the qualitative microanalysis of the turn-by-turn talk that occurs in naturally-occurring unfolding exchanges between teachers and students, and amongst students themselves. Findings from studies working within (1) language socialization, (2) critical discourse analysis, and (3) conversation analysis are explored, with particular attention paid to the ways in which these frameworks complement and complicate one another. The paper also attempts to identify areas of classroom discourse that have yet to be fully explored, and highlights the need for further research along those lines.

description: We calculate the finite-temperature shift of the critical wavevector $Q_{c}$ of the Pokrovsky-Talapov model using a renormalization-group analysis. Separating the Hamiltonian into a part that is renormalized and one that is not, we obtain the flow equations for the stiffness and an arbitrary potential. We then specialize to the case of a cosine potential, and compare our results to well-known results for the sine-Gordon model, to which our model reduces in the limit of vanishing driving wavevector Q=0. Our results may be applied to describe the commensurate-incommensurate phase transition in several physical systems and allow for a more realistic comparison with experiments, which are always carried out at a finite temperature.
Linguistic Relativity in SLA: Thinking for Speaking
Creators: name: Noguchi, Hiromi
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: Over the past few decades, Second Language Acquisition (SLA) research has shown a growing interest in linguistic relativity, specifically in Slobin’s (1987, 1996) thinking-for-speaking hypothesis. The thinking-for-speaking hypothesis posits that language-specific structures direct the speaker’s attention to specific aspects of objects and events; such perceived information is then organized according to what can be grammatically coded in the speaker’s first language (L1s). This volume probes a possible interference of L1-based cognition with second language (L2) development. As pointed out by ZhaoHong Han, the first editor, this volume regards Slobin’s thinking-for-speaking hypothesis as one of the several promising accounts for such SLA phenomena as inter- and intra- learner variability, as well as fossilization.

description: This article reflects the socio-philosophical analysis of the importance of religious values in the formation of aesthetic culture in young people. In today's developed society, national and universal, religious, cultural, aesthetic values are penetrating deeper into human life than ever before. The importance of Islamic philosophy in the improvement of the religious and aesthetic culture of the peoples of the East is great. After all, the term beauty is glorified in almost all matters of Islam. In the current globalization, it is argued that the formation of the aesthetic thinking of young people based on the values of Islam is the basis of protection against foreign ideas.

description: Solutions of the Friedmann-Lemaitre cosmological equations of general relativity have been found with finite-time singularities that are everywhere regular, have regular Hubble expansion rate, and obey the strong-energy conditions but possess pressure and acceleration singularities at finite time that are not associated with geodesic incompleteness. We show how these solutions with sudden singularities can be constructed using fractional series methods and find the limiting form of the equation of state on approach to the singularity.

Relational constructs and suicidal-crisis outcomes : examining trajectories of connectedness, disconnectedness, and burdensomeness
Creators: name: Deptuck, Halina Michele Elizabeth
Publisher: name: University of British Columbia
Year: 2023

description: Objective: Relational constructs such as connectedness, disconnectedness, and burdensomeness have been theoretically emphasized and empirically linked to suicide; however, little is known about how trajectories of these relational constructs are associated with suicide-related outcomes in helping contexts – notably, in interventions with clients in suicidal crisis. Therefore, this study examined the associations between trajectories of (a) connectedness, (b) disconnectedness, and (c) burdensomeness with outcome among suicidal clients who received crisis counseling. Methods: Using multilevel latent-growth modelling, we analyzed single-session text-based crisis intervention sessions with adults in suicidal crisis (N = 242). Results: When modelled separately, trajectories of connectedness, disconnectedness, and burdensomeness were associated with outcome. When modelled simultaneously, (a) decreases in disconnectedness had stronger associations with outcome than increases in connectedness, and (b) burdensomeness was not associated with outcome. Conclusions: While all relational constructs demonstrated associations with outcome when modelled separately, our findings indicate that connectedness and disconnectedness may be the most relevant for clients receiving single-session text-based suicidal crisis intervention. Limitations and future directions are discussed.

description: A general method for directly measuring the low-frequency flux noise (below 10 Hz) in compound Josephson junction superconducting flux qubits has been used to study a series of 85 devices of varying design. The variation in flux noise across sets of qubits with identical designs was observed to be small. However, the levels of flux noise systematically varied between qubit designs with strong dependence upon qubit wiring length and wiring width. Furthermore, qubits fabricated above a superconducting ground plane yielded lower noise than qubits without such a layer. These results support the hypothesis that localized magnetic impurities in the vicinity of the qubit wiring are a key source of low frequency flux noise in superconducting devices.

title: Computational characterization of flow and turbulence in IC engine-relevant cooling channels: An LES- and Reynolds-stress-modeling study
Creators: name: Wegt, Sebastian
Publisher: name: UNSPECIFIED
Year: 2022

description: The present work provides an insight into the flow topology of common pipe structures with the newly designed Water Spider Geometry (WSG) as a generic flow guidance of an Internal Combustion (IC) engine cooling channel, which includes flow deflection (90°-pipe bend), division (T-junction) and confluence (reverse T-junction). Therefore, a cost-efficient Large-Eddy Simulation (LES) framework for pipe structures is elaborated, which satisfies the well-known quality criteria defined in literature. The associated flow discussions enable an application-oriented assessment of the pipe structures with the focus on critical wall-abrasive flow conditions. Positions of pronounced surface degradation within the WSG detected by complementary conducted experiments (see Klink et al., 2019, and Klink and Wegt, 2021) could be attributed to the flow topology and appropriate countermeasures postulated. As a special feature, the vortex identification methodology according to Graftieaux et al. (2001) is applied to the flow discussions, which enables the identification of characteristic vortex topologies and their formation mechanisms. For further investigations within the WSG framework, an homogeneous-dissipation-concept-based elliptic-blending-related Reynolds-stress model (EBM) is formulated, calibrated and validated with a multitude of well-known benchmark cases. The formulation is based on the suggestions of Manceau and Hanjalic (2002) and Jakirlic and Maduta (2015) and combines the advantageous elliptic blending procedure for the pressure redistribution with the homogeneous specific dissipation rate concept. Furthermore, the phenomenon 'backbending' could be reliably avoided within the considered benchmark cases by a reformulation of the Simple Gradient Diffusion Hypothesis (SGDH). The extensive validation study including the WSG demonstrates the capability of the EBM to reproduce a variety of flow phenomena and confirms its suitability for further investigations.
Conversation Analysis and Second Language Pedagogy: A Guide for ESL/EFL Teachers
Creators: name: Box, Catherine
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: Conversation Analysis and Second Language Pedagogy locates itself at the nexus of research and practice, connecting the findings of conversation analysis (CA) to language teaching. In one sense, the text contributes to an existing, growing body of research that links CA to second language (L2) classroom interaction (e.g. Markee, 2000; Mori, 2002; Seedhouse, 2004; Waring, 2008). However, unlike most work in this vein, the authors are not attempting to describe verbal exchanges that occur in the L2 classroom. That is, rather than use CA to better understand how teachers and students talk, Wong and Waring aim to proffer CA as a way to teach talk. Indeed, this book specifically reaches out to ESL/EFL teachers tackling the task of improving their students’ oral proficiency. In addition to explicating basic tenets of CA findings, each chapter teems with classroom activities designed to get students speaking and analyzing talk. Thus, as the organization of the book demonstrates, the thrust of the text is twofold: (1) to introduce CA to ESL/EFL teachers, and (2) to provide them with CA-informed speaking activities for use in their classrooms.

description: Formative assessment (FA), in contrast to product-oriented summative assessment, is carried out in the classroom for the purpose of providing students with developmental feedback. Closely related to instruction, FA is done to analyze both learning goals and the instructional processes involved. This kind of classroom-based assessment can be used to raise the learners’ awareness of the language content and lesson objectives (Rea-Dickins, 2001; Rea-Dickins, 2006; Rea-Dickins & Gardner, 2000). According to Rea-Dickens (2007), good FA practices provide learners with ample opportunities for language practice through engaging them in collaborative learning activities and offering them self- and peer- assessment opportunities.

description: We construct a new realization of type-II seesaw for neutrino masses and baryon asymmetry by extending the standard model with one light and two heavy singlet scalars besides one Higgs triplet. The heavy singlets pick up small vacuum expectation values to give a suppressed trilinear coupling between the triplet and doublet Higgs bosons after the light singlet drives the spontaneous breaking of lepton number. The Higgs triplet can thus remain light and be accessible at the LHC. The lepton number conserving decays of the heavy singlets can generate a lepton asymmetry stored in the Higgs triplet to account for the matter-antimatter asymmetry in the Universe. We further introduce stable gauge bosons from a hidden sector, which obtain masses and annihilate into the Higgs triplet after spontaneous breaking of the associated non-Abelian gauge symmetry. With Breit-Wigner enhancement, the stable gauge bosons can simultaneously explain the relic density of dark matter and the cosmic positron/electron excesses.

Formative Assessment: A Cognitive Perspective
Creators: name: Theodoropulos, Christos
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: The roles of attention and awareness in second language (L2) learning have been examined extensively in a number of SLA studies. One of the findings and claims made repeatedly is that attention as awareness at the level of noticing is a necessary condition for comprehensible input to be detected, selected, processed, and potentially and partially integrated within a learner’s internalized grammar – that is, to become intake (Gass, 1988, 2003; Leow, 1995, 1997, 2000, 2001, 2003; Robinson, 1995, 2003; Rosa & O’Neill, 1999; Schmidt, 1995, 2001; Swain, 1985, VanPatten, 1996). The purpose of this discussion is to briefly illustrate how findings from these studies and, specifically, concepts such as attention, noticing, and intake can help researchers and practitioners reconceptualize the processes involved in formative assessment at the planning and implementation stages.

description: We present a new maximum-light optical spectrum of the the extremely low luminosity and exceptionally low energy Type Ia supernova (SN Ia) 2008ha, obtained one week before the earliest published spectrum. Previous observations of SN 2008ha were unable to distinguish between a massive star and white dwarf origin for the SN. The new maximum-light spectrum, obtained one week before the earliest previously published spectrum, unambiguously shows features corresponding to intermediate mass elements, including silicon, sulfur, and carbon. Although strong silicon features are seen in some core-collapse SNe, sulfur features, which are a signature of carbon/oxygen burning, have always been observed to be weak in such events. It is therefore likely that SN 2008ha was the result of a thermonuclear explosion of a carbon-oxygen white dwarf. Carbon features at maximum light show that unburned material is present to significant depths in the SN ejecta, strengthening the case that SN 2008ha was a failed deflagration. We also present late-time imaging and spectroscopy that are consistent with this scenario.

Diagnostic Second Language Assessment in the Classroom
Creators: name: Blood, Ian
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2011

description: The term diagnosis is familiar, and refers to the identification of disease or disorder in an individual. In the broadest sense, then, diagnostic second language (L2) assessment refers to any L2 assessment practice, whether in the form of a formal written test or informal teacher questioning, that yields diagnostic feedback—information on learner strengths and weaknesses.

Classroom-based Language Assessment for Young Language Learners

Publisher: name: Studies in Applied Linguistics and TESOL

description: In many countries, the age at which children officially begin to learn a foreign language in a classroom has been lowered (e.g., from middle school to elementary school) due to the belief that the earlier they start to learn a language, the more successful they will be in language learning (McKay, 2006; Pinter, 2006). Marinova-Todd et al. (2000) argue that this belief is supported by studies that show that age influences learning because “it is associated with social, psychological, educational, and other factors that can affect L2 proficiency” (p.28). In addition, in an ESL situation, many immigrant children not only have to learn the content of the classes which is taught in their non-native language, but also need to acquire that language as their second language.

description: DNA toroids are compact torus-shaped bundles formed by one or multiple DNA molecules being condensed from the solution due to various condensing agents. It has been shown that the DNA toroidal bundles are twisted. However, the global conformations of DNA inside these bundles are still not well understood. In this study, we investigate this issue by solving different models for the toroidal bundles and performing replica-exchange molecular dynamics (REMD) simulations for self-attractive stiff polymers of various chain lengths. We find that a moderate degree of twisting is energetically favorable for toroidal bundles, yielding optimal configurations of lower energies than in other bundles corresponding to spool-like and constant radius of curvature arrangements. The REMD simulations show that the ground states of the stiff polymers are twisted toroidal bundles with the average twist degrees close to those predicted by the theoretical model. Constant-temperature simulations show that twisted toroidal bundles can be formed through successive processes of nucleation, growth, quick tightening and slow tightening of the toroid, with the two last processes facilitating the polymer threading through the toroid's hole. A relatively long chain of 512 beads has an increased dynamical difficulty to access the twisted bundle states due to the polymer's topological constraint. Interestingly, we also observed significantly twisted toroidal bundles with a sharp U-shaped region in the polymer conformation. It is suggested that this U-shaped region makes the formation of twisted bundles easier by effectively reducing the polymer length. This effect can be equivalent to having multiple chains in the toroid.

Substructure Boosts to Dark Matter Annihilation from Sommerfeld Enhancement

description: The recently introduced Sommerfeld enhancement of the dark matter annihilation cross section has important implications for the detection of dark matter annihilation in subhalos in the Galactic halo. In addition to the boost to the dark matter annihilation cross section from the high densities of these subhalos with respect to the main halo, an additional boost caused by the Sommerfeld enhancement results from the fact that they are kinematically colder than the Galactic halo. If we further believe the generic prediction of CDM that in each subhalo there is an abundance of substructure which is approximately self-similar to that of the Galactic halo, then I show that additional boosts coming from the density enhancements of these small substructures and their small velocity dispersions enhance the dark matter annihilation cross section even further. I find that very large boost factors ($10^5$ to $10^9$) are obtained in a large class of models. The implications of these boost factors for the detection of dark matter annihilation from dwarf Spheroidal galaxies in the Galactic halo are such that, generically, they outshine the background gamma-ray flux and are detectable by the Fermi Gamma-ray Space Telescope.

description: We study the turbulence transition of plane Couette flow in large domains where localised perturbations are observed to generate growing turbulent spots. Extending previous studies on the boundary between laminar and turbulent dynamics we determine invariant structures intermediate between laminar and turbulent flow. In wide but short domains we find states that are localised in spanwise direction, and in wide and long domains the states are also localised in downstream direction. These localised states act as critical nuclei for the transition to turbulence in spatially extended domains.

Classroom-based Language Assessment: The Case of TAFL
Creators: name: Basheer, Nesrine

description: There was a 92% increase in the number of Arabic as Foreign Language (AFL) programs in the US between 1998 and 2002 (Wells, 2004), and in the past 10 years this trend has continued. However, this surge has not yet been met by an equally rapid activity in the field of Teaching Arabic as Foreign Language (TAFL). One particularly under-researched area is classroom-based language assessment, especially in light of the diglossic nature of Arabic. The present discussion aims to problematize the issue of classroom-based assessment in an AFL context. One major issue confronting theorists as well as practitioners is finding a clear definition of Arabic language ability in light of diglossia. A second issue has to do with training teachers to use assessment to promote learning rather than only measure students’ achievement.

The Teacher’s Role in Classroom-based Language Assessment
Creators: name: Seong, Yuna
Publisher: name: Studies in Applied Linguistics and TESOL

description: Different from large-scale language tests aiming to measure general proficiency and often administered in specific highly-controlled test settings, classroom-based language assessment is embedded in the teaching and learning cycle of a classroom and has multiple “identities” (Rea-Dickins, 2001, p. 451) due to its wide range of uses or purposes. Classroom-based language assessment is an integral part of language instruction where the teachers, as “agents” (Rea-Dickins, 2004), are the ones responsible for facilitating student learning and obtaining information about their progress and achievement, hence, also earning the name teacher assessment. From planning what to assess and how, through implementing assessment procedures and monitoring students’ performances to recording students’ attainment and progress, the teacher is constantly making decisions on how to keep track of students’ progress and attainment (Rea-Dickins, 2001). Either accomplished through a formal assessment procedure or through informal daily monitoring and observation, the teacher’s knowledge of the students guides him/her to make subsequent pedagogical decisions and push learning further.

Development and evaluation of radioimaging agents targeting prostate-specific membrane antigen
Creators: name: Lu, Kelly Fei Yuan
Publisher: name: University of British Columbia
Year: 2023

description: Prostate-specific membrane antigen (PSMA) is a transmembrane protein with an extracellular catalytic site that hydrolyzes N-acetylaspartate glutamate. It is associated with many solid cancers, and most notably prostate cancer as per its namesake. Moreover, PSMA expression correlates with prostate specific antigen expression and Gleason score which means the detected PSMA expression can be utilized to diagnose and stage prostate cancer patients. PSMA expression also has prognostic and predicative values which can further inform prostate cancer management and precision medicine. Its large extracellular domain makes it an ideal drug target for antibody and small molecule development. Antibodies are larger and have longer blood residence time and are expensive to develop, while small molecules have faster clearance and penetrance making them the ideal vector for further uses. Many lysine-urea-glutamate-based PSMA inhibitors targeting the folate enzymatic site such as [¹⁸F]DCFPyL and [⁹⁹ᵐTc]Tc- EDDA/HYNIC-iPSMA have been developed and evaluated in clinical and pre-clinical settings. However, a common problem for glutamate-based tracers is their high non-specific kidney and salivary gland uptake which can be problematic in detecting metastatic lesions and can cause side-effects like xerostomia when translating imaging-based radiopharmaceuticals into therapeutic ones. Hence, there remains a need to further optimize and increase the specificity and affinity of PSMA-targeting radiopharmaceuticals. We present a peptide-chemistry based synthesis of novel PSMA-targeting radiopharmaceuticals which is further evaluated for their in vitro and in vivo characterization based on parameters including binding affinity, hydrophilicity, labelling yield and purity, stability, biodistribution and tracer uptake, and tumour-to-background ratio in LNCaP cell and tumour xenograft models. Here, we report several successful candidates labelled with technetium-99m and fluorine-18 for SPECT and PET imaging, respectively, with ideal pharmacodynamic and pharmacokinetic properties for further pre-clinical evaluation.
Chiral currents in gold nanotubes

description: Results are presented for the electron current in gold chiral nanotubes (AuNTs). Starting from the band structure of (4,3) and (5,3) AuNTs, we find that the magnitude of the chiral currents are greater than those found in carbon nanotubes. We also calculate the associated magnetic flux inside the tubes and find this to be higher than the case of carbon nanotubes. Although (4,3) and (5,3) AuNTs carry transverse momenta of similar magnitudes, the low-bias magnetic flux carried by the former is far greater than that carried by the latter. This arises because the low-bias longitudinal current carried by a (4,3) AuNT is significantly smaller than that of a (5,3) AuNT.
