description: Effects of fermionic zero modes (bound states in a vortex core) on the rotational dynamics of vortices with sponaneously broken axisymmetry are considered. The results are compared with the Helsinki experiments where the vortex cores were driven to a fast rotation and torsional oscillations by an NMR r.f. field (Kondo et al, Phys. Rev. Lett. 67, 81 (1991)). We predict a resonance NMR absorption on localized states at the external frequency comparable with the interelevel distance, which is similar to the cyclotron Landau damping. The resonances can experimentally resolve the localized levels in vortex cores. For a pure rotation of the core, the effect depends on the relative signs of the vortex winding number and of the core rotation; thus it is sensitive to the direction of rotation of the container. The similarity with the fermionic zero modes on the fundamental strings, which simulate the thermodynamics of black holes, is discussed.

description: Rationality of the Wightman functions is proven to follow from energy positivity, locality and a natural condition of global conformal invariance (GCI) in any number D of space-time dimensions. The GCI condition allows to treat correlation functions as generalized sections of a vector bundle over the compactification of Minkowski space and yields a strong form of locality valid for all non-isotropic intervals if assumed true for space-like separations.

description: A study of secondary instabilities in ac-driven electroconvection of a planarly aligned nematic liquid crystal is presented. At low frequencies one has a transition from normal rolls to a zig-zag pattern and at high frequencies a direct transition from normal to abnormal rolls. The crossover defines a codimension-2 point. This point is also the origin of a line of homoclinic bifurcations, which enable the transition from zig-zags to abnormal rolls at lower frequencies.

description: Spin 1/2 fields localization on an asymmetric dS${}_4$ scenario, where the brane interpolates between two spacetimes dS${}_5$ and AdS${}_5$, is determined. The bulk spinor is coupled to scalar field of the brane by a nonminimal Yukawa term compatible with the scenario's geometry. We show that, independently of wall's thickness, only one massless chiral mode is localized on the wall. The massive chiral modes follow a Schrödinger equation, whose potential has a mass gap determined by Yukawa constant, which is a generic property of this system. The fermions spectrum is defined bellow the gap, by bound states of both chiralities with the same mass, and above the gap, by a continuous spectrum with local and global resonant modes of both chiralities and different mass.

description: In big cities of developing countries with fast changes, land price always acts as a key role in land use management. Therefore, exploring spatially implicit information in the spatial pattern of relationships between land prices and related impact factors is important. Taking Wuhan city as an example, the thesis applied geographically weighted regression (GWR) analysis to reveal the relationships. Based on the coefficients obtained from GWR analysis, the impact factors were proved to be spatially non-stationary. The distance to the nearest CBD had negative effects on the price mostly in central, northeastern and southwestern areas, including mainly Qingshan, Jiangan and Hongshan. In Jianghan, Hanyang, Wuchang and Hongshan, there’re clusters of education centers, so it’s significantly negative between the price and distance to the nearest education center. There were overall negative effects on the price from the distance to the nearest metro, park and lake, with the park the least significant. The outputs are promising for planners to quantitatively evaluate land price and make area-specific strategies.
Application of flume testing to field-scale beach slope prediction

Year: 2017

description: Tailings beach slope is a key parameter in design of tailings storage facilities. It influences the deposition plan, facility footprint, storage capacity and staging. This paper presents a method for applying existing analytical models to flume test and other rheological test results to allow the prediction of field-scale tailings beach slopes. Several authors have proposed analytical and testing methods for predicting tailings beach profiles. Flume tests are often used during design to provide an indication of how the tailings may beach. However, the application of flume test data to full-scale facilities has several limitations. Flume tests tend to yield much steeper beach slopes than those measured in the field. The success in scaling flume test results to full-scale facilities is mixed, at best. This paper demonstrates how an analytical model based on solid and fluid mechanics principles can be applied to scale-up flume test results to field-scale beaches. The method takes into account the differences in scale and tailings flow rate between the flume and the field. The paper discusses how to account the non-linear degradation of yield stress observed for non-segregating thickened or polymer-treated tailings. The beach slope prediction method is applied to flume test and rheological data for polymer-treated mature fine tailings from two existing oil sands mines.

Spatiotemporal and Mechanistic Analysis of Nkx2.2 Function in the Pancreatic Islet

description: Pancreatic beta cell specification is a complex process, requiring proper function of numerous transcription factors. Nkx2.2 is a transcription factor that is crucial for beta cell formation, and is expressed early and throughout pancreatic development. Nkx2.2-/- mice display complete loss of the beta cell lineage and defects in the specification of other endocrine cell types, demonstrating the importance of Nkx2.2 in establishing proper endocrine cell ratios. Recent studies have also demonstrated a role for Nkx2.2 within the mature beta cell to maintain identity and function.
      This thesis work investigated the timing of pancreatic beta cell specification and the mechanism of this process. In these studies, Nkx2.2 was ablated specifically within the Ngn3-expressing endocrine progenitor population in vivo. These mice displayed defects similar to Nkx2.2-/- mice. Surprisingly, the disruption of endocrine cell specification did not require loss of expression of multiple essential transcription factors known to function downstream of Nkx2.2, including Ngn3, Rfx6, and NeuroD1. While these factors are all necessary for beta cell specification, their preserved expression did not rescue beta cell formation. ChIP-Seq analyses also revealed co-occupancy of Nkx2.2, Rfx6, and NeuroD1 near endocrine-related genes, suggesting Nkx2.2 may cooperate with its downstream targets to regulate beta cell fate. These results have revealed a unique requirement for Nkx2.2 during a critical window of beta cell development.
      In addition, the role of a conserved domain of Nkx2.2, the specific domain (SD), was assessed using Nkx2.2SDmutant mice. Transcriptional profiling of Nkx2.2SDmutant endocrine progenitors revealed a critical role for the SD domain in regulating the transcription of endocrine fate genes early in the process of endocrine differentiation. In addition, beta cell-specific deletion of the Nkx2.2 SD domain resulted in hyperglycemia, glucose intolerance and dysregulation of beta cell functional genes. This suggests the SD domain is important for mediating Nkx2.2 function within the beta cell to maintain glucose homeostasis.
      Together, these results have elucidated a critical developmental window for beta cell specification and demonstrated an essential role for Nkx2.2 and specifically its SD domain in this process. Furthermore, these studies suggest that beta cell transcription factors may also regulate endocrine fate in a combinatorial manner, and exert changes within the endocrine progenitor lineage. These findings have provided us with a better understanding of in vivo pancreatic development, and will improve current research efforts to differentiate beta cells in vitro from hPSCs.

description: Layered van der Waals ferromagnets are promising candidates for designing new spintronic devices. Here we investigated the critical properties and magnetocaloric effect connected with ferromagnetic transition in layered van der Waals VI$_3$ single crystals. The critical exponents $β= 0.244(5)$ with a critical temperature $T_c = 50.10(2)$ K and $γ= 1.028(12)$ with $T_c = 49.97(5)$ K are obtained from the modified Arrott plot, whereas $δ= 5.24(2)$ is obtained from a critical isotherm analysis at $T_c = 50$ K. The magnetic entropy change $-ΔS_M(T,H)$ features a maximum at $T_c$, i.e., $-ΔS_M^{max} \sim$ 2.64 (2.27) J kg$^{-1}$ K$^{-1}$ with out-of-plane (in-plane) field change of 5 T. This is consistent with $-ΔS_M^{max}$ $\sim$ 2.80 J kg$^{-1}$ K$^{-1}$ deduced from heat capacity and the corresponding adiabatic temperature change $ΔT_{ad}$ $\sim$ 0.96 K with out-of-plane field change of 5 T. The critical analysis suggests that the ferromagnetic phase transition in VI$_3$ is situated close to a three- to two-dimensional critical point. The rescaled $ΔS_M(T,H)$ curves collapse onto a universal curve, confirming a second-order type of the magnetic transition and reliability of the obtained critical exponents.

description: Cardiac arrhythmias are caused by disordered propagation of electrical activity.  Progress in understanding and controlling arrhythmias requires novel methods to characterize and control the spatiotemporal propagation of electrical activity.  We used patterned illumination of cardiomyocytes derived from optogenetic human induced pluripotent stem cells to create dynamic conduction blocks, and to test spatially extended control schemes.  Using this model, we demonstrated the ability to initiate, circumscribe, relocate, and terminate pathologic spiral waves that drive many arrhythmias. When cells were derived from patients with long QT syndrome, longer action potential durations made spiral waves more resistant to termination.  This work lays the foundation for personalized models of cardiac injury and disease, and the development of tailored approaches to the management of arrhythmias.

description: $Λ^+_c$- and $Λ_b$-hypernuclei are studied in the quark-meson coupling (QMC) model. Comparisons are made with the results for $Λ$-hypernuclei studied in the same model previously. Although the scalar and vector potentials felt by the $Λ$, $Λ_c^+$ and $Λ_b$ in the corresponding hypernuclei multiplet which has the same baryon numbers are quite similar, the wave functions obtained, e.g., for $1s_{1/2}$ state, are very different. The $Λ^+_c$ baryon density distribution in $^{209}_{Λ^+_c}$Pb is much more pushed away from the center than that for the $Λ$ in $^{209}_Λ$Pb due to the Coulomb force. On the contrary, the $Λ_b$ baryon density distributions in $Λ_b$-hypernuclei are much larger near the origin than those for the $Λ$ in the corresponding $Λ$-hypernuclei due to its heavy mass. It is also found that level spacing for the $Λ_b$ single-particle energies is much smaller than that for the $Λ$ and $Λ^+_c$.

A junior subjective synonym of Tenthredo (Elinora) baetica Spinola, 1843, synonymy with Elinora baetica by Benson (1968: 183).
Types. Allantus Dusmeti [sic!] Konow, 1894a: 96. Syntypes ♂ ♀ “Hispania [...] Madrid und bei Rivas ”. Lectotype ♀ hereby designated (SDEI, Fig. 19, see also http://dx.doi.org/10.6084/m9.figshare.821216) Type locality: Spain: Madrid. Paralectotypes: 1 ♀ (MNCN _ Ent 82398), 1 ♂ (MNCN _ Ent 82399, http://dx.doi.org/10.6084/ m9.figshare.850213) both from Rivas, leg. Dusmet, 14–5– [18]93, MNCN Cat. Tipos Nº 2270.
Discussion. Benson (1968: 183) designated a lectotype from the SDEI collection (see http://dx.doi.org/ 10.6084/m9.figshare.816890). According to the reverse of the data label, this specimen was collected on 14-5- [190]2. Therefore, Benson’s designation is invalid. Benson’s systematic placement as a synonym of the highly variable Tenthredo baetica seems to be correct. Currently, it is considered to belong to the Iberian nominotypical subspecies (Taeger et al. 2010). The status of the more widely distributed subspecies Tenthredo (Elinora) baetica dominiquei (Konow, 1894b) is doubtful because of the overlapping distribution areas. It is not unlikely that dominiquei is a synonym of baetica, and that in this case subspecies cannot be separated.

description: Nach der herkömmlichen Definition stellt die Lumineszenz einen Überschuß über die Wärmestrahlung eines Mediums dar und tritt nur während oder nach geeigneter Anregung auf.
Aufgrund eigener spektroskopischer Untersuchungen zur Frage der galvanomagnetischen Lumineszenz von Eigenhalbleitern ist erwiesen, daß bei der Ausbildung der charakteristischen Inhomogenität an freien Ladungsträgern unter der Wirkung der Lorentzkraft in bestimmten Spektralbereichen auch ein Defizit an Wärmestrahlung auftreten kann, das folgerichtig als negative Lumineszenzstrahlung anzusprechen ist. Der Begriff der Lumineszenz ist entsprechend zu erweitern.
Die Strahlungsprozesse, die mit der Trägerinhomogenität verbunden sind, lassen sich quantitativ mit Hilfe der von van Roosbroeck und Shockley aufgestellten Modelltheorie der Rekombinationsstrahlung für Elektronen und Löcher im Sinne eines detaillierten Gleichgewichtes in ihrer spektralen Intensitätsfunktion angeben. Die Trägerdichte läßt sich ihrerseits mit Hilfe der Kontinuitätsgleichung unter Beachtung der durch die Oberflächenrekombinationsgeschwindigkeiten gegebenen Randbedingungen in ihrer Ortsabhängigkeit berechnen.
Unter Berücksichtigung der Reabsorption der Rekombinationsstrahlung in der Probe ergibt sich eine befriedigende Übereinstimmung der berechneten und gemessenen negativen Lumineszenzstrahlung.

description: Ground Improvement provides solutions for a variety of geotechnical and environmental issues faced by operators of mine tailings facilities. Typical challenges include: excess fluid waste that does not decant water naturally due to fines content, dam instability and excessive settlement, leaking beneath dams, and the inability of operators to cap existing tailings facilities. Another concern may be the inability to place solid material and vegetation on top of the pond during the reclamation phase. There are a variety of proven ground improvement techniques that can be utilized to solve each of the issues above. This paper will present two case histories describing the use of ground improvement (wick drains and jet grouting) to improve tailings facilities.

description: We investigate the linear stability of a thin, suspended, annular film of conducting fluid with a voltage difference applied between its inner and outer edges. For a sufficiently large voltage, such a film is unstable to radially-driven electroconvection due to charges which develop on its free surfaces. The film can also be subjected to a Couette shear by rotating its inner edge. This combination is experimentally realized using films of smectic A liquid crystals. In the absence of shear, the convective flow consists of a stationary, azimuthally one-dimensional pattern of symmetric, counter-rotating vortex pairs. When Couette flow is applied, an azimuthally traveling pattern results. When viewed in a co-rotating frame, the traveling pattern consists of pairs of asymmetric vortices. We calculate the neutral stability boundary for arbitrary radius ratio $α$ and Reynolds number ${{\cal R} e}$ of the shear flow, and obtain the critical control parameter ${\cal R}_c (α, {{\cal R} e})$ and the critical azimuthal mode number ${m_c (α, {{\cal R} e})}$. The Couette flow suppresses the onset of electroconvection, so that ${\cal R}_c (α, {{\cal R} e}) > {\cal R}_c (α,0)$. The calculated suppression is compared with experiments performed at $α= 0.56 $ and $0 \leq {{\cal R} e} \leq 0.22 $.

Specializations and Clinical Judgments of Social Workers in Cases of Children of Alcohol Abusers
Creators: Levy, Alan J.
Publisher: name: Columbia University
Year: 1988
Subjects: Social service

description: A nationally drawn sample of 228 clinical social workers made clinical judgments on three case vignettes that represented typical cases involving children of alcohol abusers. Each vignette contained parental alcohol abuse, adult mental health problems, child behavior problems, and problems in family functioning. Respondents were classified as specialists in children and youth, families, mental health, or alcohol/drug abuse, generalists (three or more specialization areas), or non-specialists (no specialization areas) on specialization scales. Scales measuring case problem perceptions, referral patterns, and treatments were developed from factor scores of responses to vignettes. Construct and content validity were established. The primary hypothesis was that specialists would assess and develop treatment plans that were congruent with their specializations. Differences among groups in case problem perception, referral pattern, and treatment scales were analyzed via analyses of variance. Hierarchical regressions were employed to determine whether particular specialization groups developed congruent case perceptions and treatment plans. Some systematic differences in clinical judgments among specialists were found, primarily in predicted directions. Generalists were the most likely to make comprehensive clinical judgments. Regressions partially supported the main hypothesis. Specialization accounted for modest portions of the variance. Case perceptions accounted for little of the variance in referrals but for none of the variance in treatment. It was concluded that specialization interacts with other contextual factors to influence clinical judgments. Implications included the necessity for broad assessments that are connected to treatment plans and broader training for clinicians to better address the complex nature of these cases.

description: We present a method to characterize non-Abelian anyons that is based only on static measurements and that does not rely on any form of interference. For geometries where the anyonic statistics can be revealed by rigid rotations of the anyons, we link this property to the angular momentum of the initial state. We test our method on the paradigmatic example of the Moore-Read state, that is known to support excitations with non-Abelian statistics of Ising type. As an example, we reveal the presence of different fusion channels for two such excitations, a defining feature of non-Abelian anyons. This is obtained by measuring density-profile properties, like the mean square radius of the system or the depletion generated by the anyons. Our study paves the way to novel methods for characterizing non-Abelian anyons, both in the experimental and theoretical domains.

Human rights--Philosophy

description: Human rights advocates seem to buy into only the “Magna Carta” theory of human rights. That is, for the most part, they point only to written instruments like the Bill of Rights or the ICCPR to define what our human rights are. These rights are ordained and granted by the elites and the powerful. This has its merits. However, I argue that, although written instruments are important, in the United States our system is based on the idea that we set our own human rights through a lived constitutional system that facilitates the reification of the values of the people. The people do not need to be granted our own rights because we are the referent to which any right must cohere. That is, beyond courts, gods, societies, ethnic groups, and treaties, there is the people, and it is up to us to decide what counts as a “human right.”

Given this idea of human rights, despite what one may think, Special Operations forces can and do protect human lives, human rights, and our constitutional legitimacy in counter- terrorism situations. They are the most effective response to global decentralized terrorist groups. They are capable of fighting amongst civilians, protecting and sparing civilian life, in ways that conventional military forces are not. They spare other soldiers’ lives by carrying out tasks that would take a higher death toll on conventional military units. They work with locals in ways that older counter-insurgency scholars could not have imagined possible. They are more capable of taking hostages and rendering enemies hors de combat than conventional military units. Finally, in doing all this the protect the legitimacy of our human rights regime, the legitimacy of our Constitution, and most importantly innocent people.

description: Why have group-party alliances become more common since the mid-twentieth century? This dissertation employs both qualitative and statistical tools to address the puzzle of contemporary special interest partisanship. After tracing partisanship across several measures, I develop a continuum of group-party relationships, running from fluid, unstructured interactions (akin to political pluralism) to highly institutionalized alliances (as we might see in a firm). Drawing on pluralist scholarship and theories of firm formation and evolution, I explore the costs and benefits of different arrangements, and explain why we might expect to see movement along the continuum over time. On the one hand, pluralism offers flexibility to parties and groups, and alliances have little value when parties are too weak to discipline their members in Congress. On the other, institutionalized alliances offer significant efficiency gains, which are especially valuable during periods of growth. I argue that changes in group-party relations stem from the growth of national party organizations over the second half of the twentieth century, which increased the value of group resources and intensified parties' need for efficiency. Until this period, parties were weak on the national level and strong on the state and local levels, and patronage was the primary currency of politics, leaving little room for issues in political competition. The New Deal's historic expansion of federal power disrupted this balance, temporarily strengthening local parties by offering new sources of patronage, while also sparking gradual, interconnected processes that would ultimately undermine machine power--most notably, the growth of groups and the rise of issue politics as a site of electoral competition. Realizing the economies of scale necessary to build strong national parties required movement away from pluralism into more structured, long-term relationships. Moreover, in order for the new site of competition to help Republicans build a coalition to compete with the long-dominant New Deal Democrats, distinct issue positions were necessary. The result of this party-building process is a pattern of group-party alliances quite unlike the bipartisan relations V.O. Key, David Truman, and others observed in the mid-twentieth century.

description: The synthesis of ultralow-noise microwaves is of both scientific and technological relevance for timing, metrology, communications and radio-astronomy. Today, the lowest reported phase noise signals are obtained via optical frequency-division using mode-locked laser frequency combs. Nonetheless, this technique ideally requires high repetition rates and tight comb stabilisation. Here, a soliton microcomb with a 14 GHz repetition rate is generated with an ultra-stable pump laser and used to derive an ultralow-noise microwave reference signal, with an absolute phase noise level below -60 dBc/Hz at 1 Hz offset frequency and -135 dBc/Hz at 10 kHz. This is achieved using a transfer oscillator approach, where the free-running microcomb noise (which is carefully studied and minimised) is cancelled via a combination of electronic division and mixing. Although this proof-of-principle uses an auxiliary comb for detecting the microcomb's offset frequency, we highlight the prospects of this method with future self-referenced integrated microcombs and electro-optic combs, that would allow for ultralow-noise microwave and sub-terahertz signal generators.

Turing Instability in a Boundary-fed System

description: The formation of localized structures in the chlorine dioxide-idodine-malonic acid (CDIMA) reaction-diffusion system is investigated numerically using a realistic model of this system. We analyze the one-dimensional patterns formed along the gradients imposed by boundary feeds, and study their linear stability to symmetry-breaking perturbations (Turing instability) in the plane transverse to these gradients. We establish that an often-invoked simple local linear analysis which neglects longitudinal diffusion is inappropriate for predicting the linear stability of these patterns. Using a fully nonuniform analysis, we investigate the structure of the patterns formed along the gradients and their stability to transverse Turing pattern formation as a function of the values of two control parameters: the malonic acid feed concentration and the size of the reactor in the dimension along the gradients. The results from this investigation are compared with existing experiments.

description: Student stories are a potentially rich natural resource running through the veins of our schools, but this resource sometimes goes untapped. One strategy teachers can use to take advantage of this resource is to formally introduce oral storytelling into the classroom--to explicitly teach students how to choose and craft stories from their lives and then allow them to publicly perform those stories. The Story Shop Community Education Program (a pseudonym) in New York City is a non-profit devoted to bringing the art and craft of oral storytelling to populations that might not otherwise have access to it through series of free workshops.
      This research project took place over sixteen weeks of one such workshop at a Title I public high school in East New York, Brooklyn. It addresses the following question: How does an oral storytelling unit affect both individual students and their classroom relationships? More specifically, (1) How do individual students engage with an oral storytelling unit? (2) What is the perceived impact of an oral storytelling unit on classroom relationships? (3) How do students perceive the impact of an oral storytelling unit both on their understanding of themselves as individuals and on their relationships with each other? and (4) How does the teacher perceive the impact of an oral storytelling unit on her individual students and her classroom relationships?
      Drawing on an interpretivist/social network approach and grounded in the tenets of narrative qualitative research, this project utilizes mixed methods to investigate whether an oral storytelling unit provided students with opportunities for growth in identity development and deepening of their classroom relationships. This investigation documents how granting students the time and space to bear witness to each other's lives and `go public' with stories that could otherwise go unheard might improve classroom community and therefore student motivation.

description: The emergence of limbs in vertebrates represents a significant evolutionary innovation. Limbs facilitate diverse motor behaviors, yet require spinal networks that can coordinate the activities of many individual muscles within the limb. Here I describe several efforts to characterize the specification of spinal motor neurons and assembly of spinal circuits in higher vertebrates. I discuss the formation of selective presynaptic sensory inputs to motor pools, a process which has long been thought to occur in an activity-independent manner. I demonstrate an as yet unappreciated role of activity-dependent refinement in patterning the set of sensory-motor connections that link motor pools with synergist function. I also explore the genetic specification of motor pools that project to defined muscle targets. I show that the motor pools that control digits engage distinct developmental genetic programs which reflect underlying differences in Hox and retinoic acid signaling. The divergent mechanisms underlying the specification of digit-innervating motor neurons may reflect the unique status of digit control in the evolution of motor behavior.
