description: "The Spin Foams for People Without the 3d/4d Imagination" could be an alternative title of our work. We derive spin foams from operator spin network diagrams} we introduce. Our diagrams are the spin network analogy of the Feynman diagrams. Their framework is compatible with the framework of Loop Quantum Gravity. For every operator spin network diagram we construct a corresponding operator spin foam. Admitting all the spin networks of LQG and all possible diagrams leads to a clearly defined large class of operator spin foams. In this way our framework provides a proposal for a class of 2-cell complexes that should be used in the spin foam theories of LQG. Within this class, our diagrams are just equivalent to the spin foams. The advantage, however, in the diagram framework is, that it is self contained, all the amplitudes can be calculated directly from the diagrams without explicit visualization of the corresponding spin foams. The spin network diagram operators and amplitudes are consistently defined on their own. Each diagram encodes all the combinatorial information. We illustrate applications of our diagrams: we introduce a diagram definition of Rovelli's surface amplitudes as well as of the canonical transition amplitudes. Importantly, our operator spin network diagrams are defined in a sufficiently general way to accommodate all the versions of the EPRL or the FK model, as well as other possible models. The diagrams are also compatible with the structure of the LQG Hamiltonian operators, what is an additional advantage. Finally, a scheme for a complete definition of a spin foam theory by declaring a set of interaction vertices emerges from the examples presented at the end of the paper.

description: We investigate fundamental processes that govern dynamics of vortex nucleation in sub-100 nm mesoscopic magnets. We focus on a structure with broken symmetry - Pacman-like nanomagnet shape - in which we study micromagnetic behavior both by means of a simple model and numerically. We show that it is possible to establish desired vortex chirality and polarity by applying only quasi-static in-plane magnetic field along specific directions. We identify the modes of vortex nucleation that are very robust against external magnetic field noise. These vortex nucleation modes are common among wide range of sub-100 nm magnets with broken rotational symmetry.

description: We present a simple but highly efficient source of polarization-entangled photons based on spontaneous parametric down-conversion (SPDC) in bulk periodically poled potassium titanyl phosphate crystals (PPKTP) pumped by a 405 nm laser diode. Utilizing one of the highest available nonlinear coefficients in a non-degenerate, collinear type-0 phase-matching configuration, we generate polarization entanglement via the crossed-crystal scheme and detect 0.64 million photon pair events/s/mW, while maintaining an overlap fidelity with the ideal Bell state of 0.98 at a pump power of 0.025 mW.

The influence of K-12 schooling on the identity development of multiethnic students
Creators: name: Mohan, Erica
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the influence of K-12 schooling on the racial and ethnic identity development of 23 self-identified multiethnic students attending high schools across the San Francisco Bay Area. All of the students participated in a semi-structured interview, nine participated in one of two focus groups, and five completed a writing activity. I approached this study with a postpositivist realist conception of identity (Mohanty, 2000; Moya, 2000a/b) that takes seriously the fluidity and complexity of identities as well as their epistemic and real-world significance. In defining racial and ethnic identity formation, I borrowed Tatum’s (1997) understanding of it as “the process of defining for oneself the personal significance and social meaning of belonging to a particular racial [and/or ethnic] group” (p. 16). The findings from this study indicate that the formal aspects of schooling (e.g., curriculum and diversity education initiatives) rarely directly influence the racial and ethnic identity development of multiethnic students. They do, however, shape all students’ racial and ethnic understandings and ideologies, which in turn shape the informal aspects of schooling (e.g., interactions with peers and racial and ethnic divisions within the student body) which exert direct influence over multiethnic students’ experiences and identities. Of course, schooling is not alone in shaping the racial and ethnic understandings and ideologies of the general student body; other influences such as family and neighborhood context cannot be discounted. Nevertheless, the findings indicate that schools are sites of negotiation, that these negotiations influence multiethnic students’ identities, and that these negotiations occur in the context of, and are shaped by, both formal and informal aspects of schooling, including, but not limited to, school demographics, curricula, race and ethnicity-based student organizations, and interactions between all members of the school community. Based on the findings, it is recommended that educators infuse the curriculum and classroom discussions with issues of race, ethnicity, multiethnicity, and difference; actively engage in the process of complicating, contesting, and deconstructing racial and ethnic categories and their classificatory power; and end the silence regarding multiethnicity in schools and ensure its authentic inclusion in the curriculum.
Why Sphingosine Has Great Potential in Treating Cancer.pdf
Creators: name: Brian, Steven
Publisher: name: figshare
Year: 2023
Subjects: Synthetic biology

description: Sphingosine kinase is an enzyme that plays a crucial role in the regulation of cell growth, survival, and differentiation by catalyzing the conversion of sphingosine to sphingosine-1-phosphate (S1P). S1P is a bioactive lipid molecule that functions as a signaling molecule and is involved in various cellular processes, including cell proliferation, angiogenesis, and immune cell trafficking. Dysregulation of sphingosine kinase and S1P signaling has been implicated in the development and progression of several diseases, including cancer, inflammation, and autoimmune disorders. In recent years, sphingosine kinase inhibitors have emerged as a promising class of anticancer agents. These inhibitors block the activity of sphingosine kinase, leading to decreased levels of S1P and subsequent inhibition of downstream signaling pathways. Preclinical studies have demonstrated the potential of sphingosine kinase inhibitors in inhibiting tumor growth and metastasis in various cancer models, including breast, prostate, and lung cancer. Several sphingosine kinase inhibitors have entered clinical trials, and the results have been promising. However, there are still significant challenges to be addressed, including toxicity and the need for more effective and specific inhibitors. The purpose of this paper is to provide an overview of the mechanisms of action of sphingosine kinase inhibitors and the current state of research on their efficacy and safety in preclinical and clinical trials. By examining the latest findings in this field, we aim to highlight the potential of sphingosine kinase inhibitors as a novel class of anticancer agents and identify the challenges that need to be overcome to develop more effective and safer treatments for cancer patients

description: We have evaluated the optical and electrical properties of a far-infrared (IR) transparent electrode for extrinsic germanium (Ge) photoconductors at 4 K, which was fabricated by molecular beam epitaxy (MBE). As a far-IR transparent electrode, an aluminum (Al)-doped Ge layer is formed at well-optimized doping concentration and layer thickness in terms of the three requirements: high far-IR transmittance, low resistivity, and excellent ohmic contact. The Al-doped Ge layer has the far-IR transmittance of >95 % within the wavelength range of 40--200 microns, while low resistivity (~5 ohm-cm) and ohmic contact are ensured at 4 K. We demonstrate the applicability of the MBE technology in fabricating the far-IR transparent electrode satisfying the above requirements.

Moreover, we show that the fully planar B12F6 cluster is more stable than the 3D counterpart. These results open up the possibility of designing larger boron based nanostructures starting from quasi-planar or fully planar building blocks.

description: Extramedullary hematopoiesis occurs in bone marrow disorders and is most commonly seen in thalassemia and myelofibrosis. We present a case of a 58 year-old male, with a history of thalassemia, which presented with a para-vertebral mass composed of hematopoietic tissue. When considering the differential diagnosis, a primary concern was an extramedullary proliferation of neoplastic hematopoietic elements, like extramedullary myeloid sarcoma. Neoplastic extramedullary proliferations can consist of triline age marrow elements and closely mimic the appearance of benign extramedullary hematopoiesis. The morphologic appearance may be a diagnostic clue, but cannot be completely relied upon.

Does appearance matter? : school bullying and body-esteem in early adolescence
Creators: name: Dittrick, Crystal June
Publisher: name: University of British Columbia
Year: 2010

description: The present study integrates previous research in two distinct but related areas to address the links between physical size/weight, as measured by Body Mass Index (BMI), body-esteem, and peer bullying. Previous research on bullying has shown that being a victim of bullying is associated with lower levels of body-esteem; previous research has also shown that peer teasing, particularly teasing about physical appearance, partially mediates the relationship between BMI and body-esteem. Replicating and extending this research, the present study explored whether peer victimization, like teasing, serves to partially mediate the link between BMI and body-esteem, considering both general bullying and specific forms of bullying as well as bullying targeted directly at physical appearance/weight among both boys and girls in middle school (N = 801). As in prior research, high BMI was associated with poor body-esteem for girls, although for boys both high and low BMI were associated with poor body-esteem for boys (quadratic relation). As well, links between victimization and different aspects of body-esteem were demonstrated, particularly for body-esteem about appearance and weight for girls, and for all types of body-esteem (appearance, weight, and attribution) for boys. Moreover, peer victimization was found to serve as a partial mediator in the relationship between BMI and body-esteem for girls and boys. For girls, verbal victimization and victimization about physical appearance, weight, and body shape served as partial mediators in the relationship between BMI and appearance body-esteem, as well as BMI and weight body-esteem. For boys, a similar meditational role of victimization was demonstrated, but only for those who were above average in weight. Future directions, limitations, strengths, unique contributions, and implications are discussed.

description: Aims

In a prospective randomised study the diagnostic accuracy of frozen section service of conventional and telepathological procedures was compared for routine breast surgery.

Material and Methods

In the telepathological approach the surgeon performed the gross examination and macroscopic cutting directly supervised via videoconference by a pathologist. Then a technician prepared the frozen sections and the staining. The on-line histological diagnosis was done using a remote controlled robotic microscope. The images were transferred to the computer screen of the pathologist. In the conventional mode, the pathologist himself manually performed the gross and microscopic tissue examination in the same laboratory. The material was restricted to breast specimens and the number of participating surgeons was limited in order to obtain comparable results. All in all, 81 routine frozen sections of the breast were included in the study within seven months.

Results

The overall diagnostic concordance of both approaches with the definite diagnosis based upon paraffin embedded tissue was calculated to 95,1 % (77/81 cases). The telepathology arm revealed 94,3 % (33/ 35 cases), and the conventional arm 95,7% (44/46 cases). Two cases of each arm remained uncertain. The median diagnostic time was calculated to 9 minutes in the conventional mode and to 17 minutes for telepathology. Not included are median 3 minutes for transportation and 12 minutes for slide preparation.

Discussion

Telepathology can replace successfully conventional performance of frozen section service within the same range of diagnostic accuracy.

description: Species introduced through human-related activities beyond their native range, termed alien species, have various impacts worldwide. The IUCN Environmental Impact Classification for Alien Taxa (EICAT) is a global standard to assess negative impacts of alien species on native biodiversity. Alien species can also positively affect biodiversity (for instance, through food and habitat provisioning or dispersal facilitation) but there is currently no standardized and evidence-based system to classify positive impacts. We fill this gap by proposing EICAT+, which uses 5 semiquantitative scenarios to categorize the magnitude of positive impacts, and describes underlying mechanisms. EICAT+ can be applied to all alien taxa at different spatial and organizational scales. The application of EICAT+ expands our understanding of the consequences of biological invasions and can inform conservation decisions.

description: La hipótesis sobre la que se construye este trabajo parte de la idea que actualmente la mayor parte de los adolescentes españoles no adquieren, tras su paso por la Educación Secundaria Obligatoria, un concepto pleno y consciente de identidad europea. Ignoran además muchas de las formas en las que la Unión Europea influye en sus vidas, lo que favorece el crecimiento de movimientos populistas y euroescépticos, vinculados a sentimientos xenófobos y nacional-populistas que muestran rechazo hacia la apertura y diversidad cultural que actualmente caracteriza la mayor parte de las sociedades europeas. En tal contexto, se cree que una modificación de las pautas educativas sobre las que se desarrolla la enseñanza hoy en día en España puede promover la mejor implantación de la dimensión europea de la educación y, con ella, la correcta asimilación de la identidad y ciudadanía europea por parte del alumnado. Para comprobar y desarrollar tal hipótesis, se formulan los siguientes objetivos: 1. Analizar los contenidos relacionados con la Unión Europea y los conceptos de identidad y ciudadanía europea que se imparten y han impartido en la ESO en las últimas décadas. 2. Determinar el conocimiento real que los alumnos del segundo ciclo de la ESO poseen sobre la Unión Europea tras la finalización de la enseñanza obligatoria. 3. Desarrollar una propuesta didáctica integral, para el conjunto de la ESO, que permita implementar de manera efectiva en este nivel educativo la dimensión europea de la educación y, con ella, la transmisión de la idea de identidad y ciudadanía europea.

description: We describe the dynamics of a stream of equally spaced macroscopic particles in orbit around a central body (e.g. a planet or star). A co-orbital configuration of small bodies may be subject to gravitational instability, which takes the system to a spreading, disordered and collisional state. We detail the linear instability's mathematical and physical features using the shearing sheet model and subsequently track its nonlinear evolution with local N-body simulations. This model provides a convenient tool with which to understand the gravitational and collisional dynamics of narrow belts, such as Saturn's F-ring and the streams of material wrenched from tidally disrupted bodies. In particular, we study the tendency of these systems to form long-lived particle aggregates. Finally, we uncover an unexpected connection between the linear dynamics of the gravitational instability and the magnetorotational instability.

description: We consider distributed consensus and vehicular formation control problems. Specifically we address the question of whether local feedback is sufficient to maintain coherence in large-scale networks subject to stochastic disturbances. We define macroscopic performance measures which are global quantities that capture the notion of coherence; a notion of global order that quantifies how closely the formation resembles a solid object. We consider how these measures scale asymptotically with network size in the topologies of regular lattices in 1, 2 and higher dimensions, with vehicular platoons corresponding to the 1 dimensional case. A common phenomenon appears where a higher spatial dimension implies a more favorable scaling of coherence measures, with a dimensions of 3 being necessary to achieve coherence in consensus and vehicular formations under certain conditions. In particular, we show that it is impossible to have large coherent one dimensional vehicular platoons with only local feedback. We analyze these effects in terms of the underlying energetic modes of motion, showing that they take the form of large temporal and spatial scales resulting in an accordion-like motion of formations. A conclusion can be drawn that in low spatial dimensions, local feedback is unable to regulate large-scale disturbances, but it can in higher spatial dimensions. This phenomenon is distinct from, and unrelated to string instability issues which are commonly encountered in control problems for automated highways.

description: Flares result from the sudden reconnection and relaxation of magnetic fields in the coronae of stellar atmospheres. The highly dynamic atmospheric response produces radiation across the electromagnetic spectrum, from the radio to X-rays, on a range of timescales, from seconds to days. New high resolution data of solar flares have revealed the intrinsic spatial properties of the flaring chromosphere, which is thought to be where the majority of the flare energy is released as radiation in the optical and near-UV continua and emission lines. New data of stellar flares have revealed the detailed properties of the broadband (white-light) continuum emission, which provides straightforward constraints for models of the transformation of stored magnetic energy in the corona into thermal energy of the lower atmosphere. In this talk, we discuss the physical processes that produce several important spectral phenomena in the near-ultraviolet and optical as revealed from new radiative-hydrodynamic models of flares on the Sun and low mass stars. We present recent progress with high-flux nonthermal electron beams in reproducing the observed optical continuum color temperature of T~10,000 K and the Balmer jump properties in the near-ultraviolet. These beams produce dense, heated chromospheric condensations, which can explain the shape and strength of the continuum emission in M dwarf flares and the red-wing asymmetries in the chromospheric emission lines in recent observations of solar flares from the Interface Region Imaging Spectrograph. Current theoretical challenges and future modeling directions will be discussed, as well as observational synergies between solar and stellar flares.

The kesi, which has contributed to the misinterpretation of China’s practice of foreign relations, provides invaluable insight into the political strategies of the Qianlong Emperor in the face of British imperialism. The work commemorates the infamous meeting between the Emperor and the English ambassador George Macartney in 1793. The event marks the failed negotiation between two incommensurable power systems due to conflicting interests and grave misunderstandings on both sides. Yet in English and Chinese language histories, the failed negotiation is often attributed to the backwardness of China’s practice of foreign relations. Within the context of historical writing and museum display, the kesi is made to emphasize the Emperor’s cultural blindness and ignorance of the changing world beyond China. A closer reading of the kesi will reveal that its image and inscription integrates the zhigong tu genre (the official documentation of China’s foreign relations) and li (the guiding principle of China’s foreign relations). I will argue that the emperor employed the zhigong tu genre and li to assert the power of the Qing Empire and divert his criticism of British imperialism. Pictorially the kesi follows the power structuring process of li by emphasizing the contingent relationship between the supreme lord (the Qianlong Emperor) and the lesser lord (George Macartney). The kesi’s inscription, composed by the Emperor himself, embodies the core of China’s tributary practice: “In my kindness to men from afar I make generous return.” Thus far, the kesi channels the conventions of zhigong tu and manifests the principles of li. During the Qing Dynasty, the Qianlong Emperor’s materialization of his power through the appropriation of zhigong tu and li was necessary to foster domestic confidence. The kesi, marking the end of China’s tributary practice, can be alternatively understood as the Emperor’s last capacity to maintain internal stability through the Chinese tributary system.

description: We raise and investigate the following problem that one can regard as a very close relative of the densest sphere packing problem. If the Euclidean 3-space is partitioned into convex cells each containing a unit ball, how should the shapes of the cells be designed to minimize the average surface area of the cells? In particular, we prove that the average surface area in question is always at least 13.8564... .

description: We present results from a recent multidecade study of the spot activity of young solar-like stars, based on photometry gathered at the Fairborn observatory since 1987. Results from the time series analysis of this photometry reveal systematic tendencies in the stellar rotation and activity behaviour: 1) Fast rotating stars show weaker relative surface differential rotation but the absolute equator to pole differential rotation has a flat rotation dependence. 2) The lengths of activity cycles follow a set of tightly defined parallel branches when compared to the Rossby number and chromospheric activity levels. A number of stars show superimposed cycles from two different branches. 3) Active longitudes are commonly seen on the highly active stars, but on weakly active stars the long-term distribution of spot activity is axisymmetric. There appears to be a sharp boundary between the axisymmetric and non-axisymmetric regimes, suggesting a shift in the dominant dynamo modes. 4) The active longitudes have commonly significantly shorter rotation periods than the stellar surfaces, as measured directly from the shorter lived spot modulation. This may be a signature of radial differential rotation or that the active longitudes follow an azimuthal dynamo wave.

description: We show that the automorphism groups of countably categorical linear orders are extremely amenable. Using methods of Kechris, Pestov, and Todorcevic, we use this fact to derive a structural Ramsey theorem for certain families of finite ordered structures with finitely many partial equivalence relations with convex classes.

description: Cancer investigations in microarray data play a major role in cancer analysis and the treatment. Cancer microarray data consists of complex gene expressed patterns of cancer. In this article, a Multi-Objective Binary Particle Swarm Optimization (MOBPSO) algorithm is proposed for analyzing cancer gene expression data. Due to its high dimensionality, a fast heuristic based pre-processing technique is employed to reduce some of the crude domain features from the initial feature set. Since these pre-processed and reduced features are still high dimensional, the proposed MOBPSO algorithm is used for finding further feature subsets. The objective functions are suitably modeled by optimizing two conflicting objectives i.e., cardinality of feature subsets and distinctive capability of those selected subsets. As these two objective functions are conflicting in nature, they are more suitable for multi-objective modeling. The experiments are carried out on benchmark gene expression datasets, i.e., Colon, Lymphoma and Leukaemia available in literature. The performance of the selected feature subsets with their classification accuracy and validated using 10 fold cross validation techniques. A detailed comparative study is also made to show the betterment or competitiveness of the proposed algorithm.

Theory of the SrTiO3 Surface State Two-Dimensional Electron Gas

description: We present a theory of the quasi two-dimensional electron gas (2DEG) systems which appear near the surface of SrTiO$_3$ when a large external electric field attracts carriers to the surface. We find that non-linear and non-local screening by the strongly polarizable SrTiO$_3$ lattice plays an essential role in determining 2DEG properties. The electronic structure always includes weakly bound bulk-like bands that extend over many SrTiO$_3$ layers. At 2D carrier-densities exceeding $\sim 10^{14} {\rm cm}^{-2}$ tightly bound bands emerge that are confined within a few layers of the surface.

Sikh Television: Sovereignty, Religion, and Diaspora

description: This dissertation is an ethnographic study of British-based Sikh television stations. Findings are based on sixteen months of ethnographic field research in the United Kingdom and four months of ethnographic field research in India. The research specifically focuses on four stations – Sikh Channel, Sangat TV, Akaal Channel, and KTV, each based in Birmingham, whose variegated programming is broadcast twenty-four hours-a-day, seven-days-a-week. Ethnographic findings are situated historically in the context of modern subject formation, late-twentieth century Indian state violence, and Sikh memories of the tradition. Specifically, the sense-making practices involved in these stations are contextualized with respect to memories of the Sikh gurus, their teachings, and the creation of the Khalsa order. Findings show that community-operated television media offer a key vantage point from which to investigate the tensions of diasporic political subjectivity. Sikh television stations exhibit two kinds of politics that can be in tension with one another – a liberal multicultural struggle for recognition in the diaspora and an ethno-nationalist struggle for self-determination in Punjab. Media producers articulate strategic rhetorics of docility and resistance to garner quite different forms of belonging in the diaspora and homeland, respectively. At the same time, viewing publics exert their own pressures on broadcasts, informing content through off-air interventions. These media are consequently crucial resources for convening and forming emergent forms of globally dispersed sociality beyond the borders of any one state. At stake in these tensions is a tradition of thinking sovereignty that is informed by the Sikh tradition. Stations ground their authority in relation to the gurdwara setting, a translation between extant institutions and newly formed media. Sikh television stations consequently situate themselves with respect to key moments in Sikh memory, reaching back to the very foundation of the tradition and more recently to twentieth-century guerilla violence and ethnonationalism. In doing so, they reveal the increasingly mediatized site of diasporic practice, politics, and memory.
Strong Enhancement of Rashba spin-orbit coupling with increasing anisotropy in the Fock-Darwin states of a quantum dot

description: We have investigated the electronic properties of elliptical quantum dots in a perpendicular external magnetic field, and in the presence of the Rashba spin-orbit interaction. Our work indicates that the Fock-Darwin spectra display strong signature of Rashba spin-orbit coupling even for a low magnetic field, as the anisotropy of the quantum dot is increased. An explanation of this pronounced effect with respect to the anisotropy is presented. The strong spin-orbit coupling effect manifests itself prominently in the corresponding dipole-allowed optical transitions, and hence is susceptible to direct experimental observation.

description: Worldwide, the concept of self-efficacy beliefs has been investigated abundantly and found to positively affect the outcomes of university students in most subject areas including English. The existing literature yet suggests that the self-efficacy beliefs of Saudi university students to pursue their higher education using the English language in Saudi Arabia have not been investigated.The present study aimed to assess the strengths of students’ self-efficacy beliefs to complete their higher education in English, to assess the degree of relationship between self-efficacy beliefs for writing, listening, and speaking English, and to compare male students and their female counterparts on the listed variables. Descriptive, t-test, and multiple linear regression analyses were utilized to inspect the data and answer the research questions.The self-efficacy beliefs of participants were deemed strong. The correlation between general self-efficacy beliefs and writing self-efficacy was significant. The correlation between general self-efficacy and self-efficacy for listening was also significant. The multiple regression analyses showed a statistically significant effect of self-efficacy beliefs for writing and self-efficacy beliefs for listening on general self-efficacy beliefs. Results of the independent sample t-test suggested one statistically significant difference between male and female students on the self-efficacy beliefs for writing.Limitations were stated, and recommendations were made for future replications of the study.
