description: Liquids spreading over a solid substrate under the action of various forces are known to exhibit a long wavelength contact line instability. We use an example of thermally driven spreading on a horizontal surface to study how the stability of the flow can be altered, or patterns selected, using feedback control. We show that thermal perturbations of certain spatial structure imposed behind the contact line and proportional to the deviation of the contact line from its mean position can completely suppress the instability. Due to the presence of mean flow and a spatially nonuniform nature of spreading liquid films the dynamics of disturbances is governed by a nonnormal evolution operator, opening up a possibility of transient amplification and nonlinear instabilities. We show that in the case of thermal driving the nonnormality can be significant, especially for small wavenumber disturbances, and trace the origin of transient amplification to a close alignment of a large group of eigenfunctions of the evolution operator. However, for values of noise likely to occur in experiments we find that the transient amplification is not sufficiently strong to either change the predictions of the linear stability analysis or invalidate the proposed control approach.

description: In this paper, we introduce a generalization of Liu-Yang's weighted norm to linear and to nonlinear hyperbolic equations. Extending a result by Hu and LeFloch for piecewise constant solutions, we establish sharp L1 continuous dependence estimates for general solutions of bounded variation. Two different strategies are successfully investigated. On one hand, we justify passing to the limit in an L1 estimate valid for piecewise constant wave-front tracking approximations. On the other hand, we use the technique of generalized characteristics and, following closely an approach by Dafermos, we derive the sharp L1 estimate directly from the equation.

 Zovax Błeszyński, 1962: 130; type species: Prionapteryx whiteheadii Wollaston, 1879, by original designation.
DIAGNOSIS: Small to medium sized species with well-developed ocelli and frons with corneous point. Forewing with or without hook. Male genitalia with uncus and gnathos well-developed; valvae without basal costal process. Female genitalia with dorsal sclerite in subrectangular papillae anales; apophyses posteriores basally bulged; corpus bursae with lateral pouch.
 DIFFERENTIAL DIAGNOSIS: The most closely related genus seems to be Mesolia Ragonot. The male genitalia of Mesolia have flat and sclerotized coremata (Fig. 15), and the gnathos shorter than uncus. The female genitalia of Zovax are most similar to Mesolia, differing by the presence of a dorsal sclerite in the papillae anales, the apophyses posteriores basally bulged, and the corpus bursae with a moderate lateral pouch.
 REMARKS: Further investigations are needed to fully understand the phylogenetic relationships among the species of this genus. Coremata are very delicate structures, rarely considered in slide mounting. In absence of fresh material I cannot confirm the presence of coremata in Z. whiteheadii and in Z. vangoghi Błeszyński. Moreover, I could not yet study females of these two species, and they are very important for generic relationships.

How the Poor Afford Public Transportation: the Case of New York City

Subjects: Local transit--Fares

Transportation--Planning

description: This research asks how universality of ridership is maintained in New York City’s transit system given that it is gated by the fare. Transportation planning scholarship presumes transit is affordable because the fare has a relatively low price and ridership among the poor is high. The transit agency addresses universality by maintaining a fare structure that keeps the single ride fare relatively low. Its method is based on empirical evidence that low-income riders “prefer” cheaper fare products over those with lower average fares but that require higher initial cash outlays. Transportation scholarship observes that low-income riders are inelastic and presumes, based on economic theory, that riders will forego more elastic goods to ride transit.
      Critical planning scholars have contested the tenets of the modernist planning project which utilize predict-and-provide empiricism and neoclassical economic models such as these. While urban planning has turned toward direct collaboration or at least participation with affected communities, transportation planning has not fully made this turn. There is thus little transit-related research that is informed directly by riders, especially low-income riders, suggesting the conventional approaches to understanding how riders afford the fare are incomplete.
      To fill this void, this research engages with low-income transit riders to elaborate and challenge the explanations for universality of ridership. It finds that although the fare price is low, it is not necessarily affordable. The “preference” for single ride fares is in most cases the result of constraints. Single fare rides are often combined with fare evasion and exploitation of free transfers, while unlimited fare cards are highly sought and widely shared. Low-income riders are more likely to undertake compensating behaviors than to forego goods. On the occasions when they do forego goods, they compromise necessities such as food, telephone service, rent and laundry. Finally, agents of the welfare state distribute fares to low-income individuals to promote rehabilitation and labor force attachment.
      Together these findings suggest that universality of ridership is tenuous. It depends on fragmented systems of generosity, compromise and welfare of which transit advocates and planners are largely unaware. Fare evasion enforcement, pricing structures and fare payment methods can pose challenges to riders who rely on these fragmented systems. By explicitly acknowledging transit affordability, and incorporating knowledge on the role that welfare plays in enabling low-income ridership, planners can expand access to transit for low-income riders.

description: The use of electric vehicles not only drives economic growth but also contributes to the goal of "carbon peak and carbon neutrality". However, large-scale electric vehicle charging station access impacts the security and stability of the power grid. To effectively predict electric vehicle charging load, this paper builds LSTM neural network model based on PyTorch. The historical load data of a charging pile in Beijing from December 12, 2019 to February 1, 2020 was selected for analysis and prediction. Firstly, quantificat the epidemic’s impact on charging load, vectorize and normalize the historical load data. Then, the BPTT algorithm was used to train the neural network to predict the data of February 1, 2020, and the error was finally 4.17%. The prediction accuracy is much higher than that of the RNN and the CNN
How the Preservation of Archives During WWII Led to a Radical Reformation of Strategic Intelligence Efforts

History

description: In 1943, in the midst of World War Two, the Allies established what was perhaps the most unusual and unexpected army unit of the war: the Monuments, Fine Arts and Archives army unit (MFA&A), created not so much to further the war effort but specifically to address the fate of culturally significant objects. The unit placed archivists and art specialists within advancing American and British army units. Drawn from existing army divisions, these volunteers had as their mission the safeguarding of works of art, monumental buildings, and—more significantly for this study—archives, for the preserved archives ultimately produced intelligence that was valuable both to the ongoing war effort and for the post-war administration of Allied occupied Germany. Although the MFA&A division was initially created to find looted objects and protect culturally relevant material including archives, the Military Intelligence Research Section (MIRS), a joint British and American program, recognized the possible intelligence benefits that could be gained through the exploitation of captured German archives. This agency pioneered strategic intelligence, as up to this point the use of a large quantity of enemy records to develop studies quickly enough for application in then-current large-scale military operations was an untried military technique. Although a wealth of literature about fascist Germany and World War Two exists—at least some measurable part of it relying on information contained in German archives and documents captured by the Allied Forces during and after the war—the story of the archives themselves has received scant attention. This story hinges on the actions of two wartime agencies, MFA&A and MIRS. Neither of these two programs had clearly formulated missions that encapsulated their later responsibilities; both programs developed over time. These two programs changed the way the United States came to use intelligence during wartime, and the country has taken advantage of this system of exploitation of information in subsequent conflicts.

description: We present a novel method of analysis and prove finite time asymptotically self-similar blowup of the De Gregorio model \cite{DG90,DG96} for some smooth initial data on the real line with compact support. We also prove self-similar blowup results for the generalized De Gregorio model \cite{OSW08} for the entire range of parameter on $\mathbb{R}$ or $S^1$ for Hölder continuous initial data with compact support. Our strategy is to reformulate the problem of proving finite time asymptotically self-similar singularity into the problem of establishing the nonlinear stability of an approximate self-similar profile with a small residual error using the dynamic rescaling equation. We use the energy method with appropriate singular weight functions to extract the damping effect from the linearized operator around the approximate self-similar profile and take into account cancellation among various nonlocal terms to establish stability analysis. We remark that our analysis does not rule out the possibility that the original De Gregorio model is well posed for smooth initial data on a circle. The method of analysis presented in this paper provides a promising new framework to analyze finite time singularity of nonlinear nonlocal systems of partial differential equations.

description: Up-regulated genes in the lungs of endotoxemic wild-type, but not NOS2-deficient mice. We previously showed that HPV is preserved in endotoxemic NOS2-deficient (NOS2−/−) mice. [2]. The objective of this study was to identify gene products that may contribute to endotoxin-induced impairment of HPV in wild-type mice. Transcription profiling was performed on homogenized lung tissue from wild-type mice 22 h after LPS administration (N = 3) and compared to the profile produced by the lungs of wild-type mice challenged with saline LPS (N = 4). Transcription profiling was also performed on homogenized lung tissue from NOS2−/− mice 22 h after LPS administration (N = 3) and was compared to the profile produced by the lungs of NOS2−/− mice challenged with saline (N = 1). The microarray assessed the expression of 22,690 genes. A subset of 59 genes (shown in this table) was increased greater than three-fold in wild-type mice challenged with endotoxin, but was not enhanced three-fold in the lungs of NOS2−/− mice challenged with endotoxin. The microarray results indicated that Arg1 was the most highly expressed gene in endotoxemic wild-type mice, and that Arg1 expression was not increased in the lungs of endotoxemic NOS2−/− mice.

These techniques yield an explicit description of this subspace as a convex polytope, presented by a family of linear inequalities themselves accessible via a finite calculation. We completely describe this family of inequalities in a variety of familiar example cases, and as a consequence we highlight a certain member of the "XY-family" for which this subspace is particularly large, i.e., for which many two-qubit programs admit expression as low-depth circuits.

description: Previous studies of lesson preparation groups (LPG; beikezu) have not dealt with the impact of LPG on teachers’ reflective practice. This qualitative case study was an exploration of LPG group leaders’ (beike zuzhang) facilitation of LPG meetings (beike zuhui) to gain insights on reflective practices in LPG meetings. The study involved 54 participants: 29 participants (LPG group leaders and teachers) were interviewed and observed; 20 participants (teachers) were observed; and 5 participants (school leaders) were interviewed. In addition to in-depth interviews and on-site observations, two questionnaires were used to expose a holistic picture of group learning and reflection in LPG meetings. The results indicate school leaders’ perceptions and values of reflective practices have an influence on the interdependence of LPG group leaders’ preparation and facilitation of meeting content and teachers’ attitudes and engagement toward reflection in LPG meetings. School leaders expected teachers to engage in reflection inside and outside of LPG meetings, but teachers’ practices were not aligned with school leaders’ expectations, given the differing understandings of LPG goals. Schools did not have evaluative plans for reflection in LPG meetings. LPG group leaders prepared teachers to understand the upcoming week teaching content and progress. However, LPG group leaders lacked facilitation skills for encouraging reflective group discussions. They were also reluctant to deal with group dynamics challenges proactively. Teachers’ experiences of reflection depended on the purpose of meetings and meeting agendas. Teachers were more likely to engage in reflective discussions with colleagues when LPG meetings involved clear purposes, guiding questions, constructive feedback, and guided future actions. The creating reflective practice in LPG meetings model was proposed to address the interdependence between stakeholders, with the mindsets and skillsets needed for LPG group leaders and teachers. The research results represent a step toward developing school-based reflective practice professional learning communities (PLCs).

Maybe you’re planning a rural escape.Rural tourism is crucial for job growth and sustainability of small rural towns. However, for rural emergency departments, school holidays are often the busiest times.No-one plans a trip to the emergency department on holidays. But if you need health care, there are often other ways of accessing it than turning up at a rural hospital.Here’s why it’s so important to leave rural emergency departments for life-threatening illness or injuries, and some other options for seeking care.
Nonlocal Conductivity in the Vortex-Liquid Regime of a Two-Dimensional Superconductor

description: We have simulated the time-dependent Ginzburg-Landau equation with thermal fluctuations, to study the nonlocal dc conductivity of a superconducting film. Having examined points in the phase diagram at a wide range of temperatures and fields below the mean-field upper critical field, we find a portion of the vortex-liquid regime in which the nonlocal ohmic conductivity in real space is negative over a distance several times the spacing between vortices. The effect is suppressed when driven beyond linear response. Earlier work had predicted the existence of such a regime, due to the high viscosity of a strongly-correlated vortex liquid. This behavior is clearly distinguishable from the monotonic spatial fall-off of the conductivity in the higher temperature or field regimes approaching the normal state. The possibilities for experimental study of the nonlocal transport properties are discussed.

description: In future transportation systems, the charging behavior of electric Autonomous Mobility on Demand (AMoD) fleets, i.e., fleets of electric self-driving cars that service on-demand trip requests, will likely challenge power distribution networks (PDNs), causing overloads or voltage drops. In this paper, we show that these challenges can be significantly attenuated if the PDNs' operational constraints and exogenous loads (e.g., from homes or businesses) are accounted for when operating an electric AMoD fleet. We focus on a system-level perspective, assuming full coordination between the AMoD and the PDN operators. From this single entity perspective, we assess potential coordination benefits. Specifically, we extend previous results on an optimization-based modeling approach for electric AMoD systems to jointly control an electric AMoD fleet and a series of PDNs, and analyze the benefit of coordination under load balancing constraints. For a case study of Orange County, CA, we show that the coordination between the electric AMoD fleet and the PDNs eliminates 99% of the overloads and 50% of the voltage drops that the electric AMoD fleet would cause in an uncoordinated setting. Our results show that coordinating electric AMoD and PDNs can help maintain the reliability of PDNs under added electric AMoD charging load, thus significantly mitigating or deferring the need for PDN capacity upgrades.

Year: 2009

description: This paper comments on the regulatory regime at the heart of the environmental movement in Canada and focuses on the implications for mining companies arising from increased environmental regulation. A survey of senior environmental representatives from major mining companies is presented to identify management approaches that are used to reduce environmental risk and a typology is developed of Canadian mining companies based on the environmental structures in place. Finally, a checklist of structures essential to the success of any mining environmental program is discussed. The paper concludes that regulatory and public pressures have forced Canadian mining companies to considerably enhance their environmental performance. It is expected that these pressures will not abate in the foreseeable future.

description: Image compression is one of the essential methods of image processing. Its most prominent advantage is the significant reduction of image size allowing for more efficient storage and transfer. However, lossy compression is associated with the loss of some image details in favor of reducing its size. In compressed images, the deficiencies are manifested by noticeable defects in the form of artifacts; the most common are block artifacts, ringing effect, or blur. In this article, we propose three models of fully convolutional networks with different configurations and examine their abilities in reducing compression artifacts. In the experiments, we research the extent to which the results are improved for models that will process the image in a similar way to the compression algorithm, and whether the initialization with predefined filters would allow for better image reconstruction than developed solely during learning.

description: Taking control of the protein production machinery of the host cell is a required step in the life cycle of viruses. Towards this end, viruses have evolved diverse strategies of cellular mimicry and deception to hijack and steal host cell ribosomes for viral protein production. In higher eukaryotes, where translation is sophisticated and access to ribosomes intricately regulated, numerous positive strand RNA viruses have evolved structured RNA sequences to evade translation regulation mechanisms. These RNA sequences, called Internal Ribosomal Entry Sites (IRESs), use their RNA structure to hijack the eukaryotic host cell ribosomes during the highly regulated initiation phase of translation. While a select few of such IRESs have been both biochemically and structurally characterized, the diversity of IRESs isn’t fully explored. Structural basis for the working mechanism of intergenic IRESs such as the Israeli Acute Paralysis Virus IRES (IAPV-IRES) with unique RNA features and expanded coding capacity is unavailable. Similarly, structural and biochemical understanding of newly described IRESs such as the complex IRES located at the 5′ untranslated region of the Cricket Paralysis Virus (CrPV 5′-UTR-IRES) is also unavailable. This body of work uses cryo-electron microscopy (cryo-EM) and biochemistry to characterize these two IRESs.Here, we show how the IAPV-IRES uses its unique features to exploit novel binding sites and commits the IRES-ribosome complexes towards a global pre-translocation mimicry. We trace a complete path of the IRES from its initial binding with the small subunit to its formation of an elongation-ready ribosome. We show that its mechanism of ribosome hijacking is different from currently accepted mechanistic paradigm for other IRESs from viruses similar to IAPV-IRES. We also identify another divergent mechanism of ribosome hijacking used by a different type of IRES. We show that the CrPV 5′-UTR-IRES features a novel, extended, and multi-domain architecture unlike any of the previously characterized IRESs from the group it belongs to. We also show that this IRES uses its novel structure and a minimal set of initiation factors to assemble a canonical-like pre-initiation complex on the small subunit of the ribosome at an upstream start-stop open reading frame. This body of work underscores the unexplored diversity in IRESs found in single stranded positive sense viral RNA genomes, invites re-visiting of the currently standing mechanisms of cap-independent initiation carried out by IRESs, and sheds light on a possible evolutionary past where IRESs could have given rise to the current eukaryotic translation initiation system.

description: This study examines the modern history of the Hui to understand how China, a multiethnic empire-turned-nation-state, has shaped and been shaped by its many “others,” particularly its ethnic and religious minorities. The Hui, as millions of Chinese-speaking Muslims scattered throughout China are known, are unique among the People’s Republic of China’s 55 officially recognized minorities in sharing nothing in common other than a religious identity, Islam. Moreover, unlike Tibetans and Mongolians in the PRC and many minorities in other post-imperial states, the Hui inherited no system of representation from the dynastic era. This lack of political institutionalization through the Qing reign should draw attention to what remains an underexamined period in Hui history—from the fall of the Qing to the founding of the PRC in 1949—and an unexamined question—How did the Hui become a nation? Focused on the large, inland province of Henan, Hui Nation tells this story. I show that Hui nationhood was not simply an elaboration of Communist ethnic policy but rather the consequence of a bottom-up social movement. Incorporating cultural and organizational change into social history, I further argue that this movement hinged on changes in Huis’ understanding of Islam and in the institutions that connected them to one another in the first half of the twentieth century.

 DIAGNOSIS: Prionapteryx differs from Mesolia and Zovax in the male genitalia with a basal costal process on the valva and without coremata. The basal costal process is shared with Surattha, but the latter differs in having a strongly arched uncus and the phallus with a pointed tip. The female genitalia can be distinguished from those of Mesolia, Zovax and Surattha by the triangular papillae anales, the long, tubular 8th abdominal segment and by the very strongly developed intersegmental membranes between abdominal segments VII and VIII and abdominal segments VIII and IX.
 REMARKS: The genus Prionapteryx includes 57 species (Nuss et al., 2012) since Błeszyński (1967: 92) synonymized in this genus a number of genera. Some of these species have to be returned to Surattha Walker since this name was revised as valid by Bassi & Mey (2011: 234).
 On the other hand, Loxophantis has to be considered as a junior synonym of Prionapteryx as shown by the study of both external features and genitalia of the type species.

Human Engagement and the Experience of Value
Creators: Sehnert, Steen Cameron
Publisher: name: Columbia University

Subjects: subject: Psychology
subject: FOS: Psychology

description: Research on value has focused on the valence of stimuli (e.g. Thorndike, 1911) or on the way an actor engages with those stimuli (e.g. Kierkegaard, 1843). We use an approach to the study of value that understands value as an interaction between the actor and a value target, between the valence of a stimulus or activity, and a person's strength of engagement with that value target. In Experiment 1, we test the central prediction of Regulatory Engagement Theory (RET) (Higgins, 2006), that increased strength of engagement, as manipulated by inducing a situation of scarcity, intensifies the value experience associated with tasting a disliked yogurt, causing participants to feel more intensely negative about the yogurt when they perceive it as scarce. In Experiment 2, we extend this finding by testing whether manipulating the scarcity of one array of products at time 1 can create a psychological state that can transfer to intensify the value of an unrelated product presented later in the experiment. In Experiments 3 and 4 we work toward developing a measure of engagement as sustained attention in order to begin to establish strength of engagement as a mechanism for these effects. In these studies, we use Regulatory Fit (Higgins, 2000) to create conditions of strong and weak engagement within participants, and we measure engagement by recording the extent to which participants attend to a focal task at the expense of irrelevant distracting information presented during that task. By conceptualizing value as a motivational force experience, using RET to make new predictions about this experience, and developing a measure to test the mechanism itself, we hope this work contributes to the development of a new way of understanding value.
Unicellular algal growth: A biomechanical approach to cell wall dynamics

description: We present a model for unicellular algal growth as motivated by several experiments implicating the importance of calcium ions and ``loosening'' enzymes in morphogenesis. A growing cell at rest in a diffusive calcium solution is viewed as an elastic shell on short timescales. For a given turgor pressure, we calculate the stressed shapes of the wall elements whose elastic properties are determined by Young's modulus and the thickness of the wall. The local enzyme concentration then determines the rate at which the unstressed shape of a wall element relaxes toward its stressed shape. The local wall thickness is calculated from the calcium-mediated addition of material and thinning due to elongation. We use this model to calculate growth rates for small perturbations to a circular cell. We find an instability related to modulations of the wall thickness, leading to growth rates which peak at a finite wave number.

Local Density of States in a Dirty Normal Metal connected to a Superconductor

description: A superconductor in contact with a normal metal not only induces superconducting correlations, known as proximity effect, but also modifies the density of states at some distance from the interface. These modifications can be resolved experimentally in microstructured systems. We, therefore, study the local density of states $N(E,x)$ of a superconductor - normal metal heterostructure. We find a suppression of $N(E,x)$ at small energies, which persists to large distances. If the normal metal forms a thin layer of thickness $L_n$, a minigap in the density of states appears which is of the order of the Thouless energy $\sim \hbar D/L_n^2$. A magnetic field suppresses the features. We find good agreement with recent experiments of Guéron {\it et al.}

The branching structure of diffusion-limited aggregates

description: I analyze the topological structures generated by diffusion-limited aggregation (DLA), using the recently developed "branched growth model". The computed bifurcation number B for DLA in two dimensions is B ~ 4.9, in good agreement with the numerically obtained result of B ~ 5.2. In high dimensions, B -> 3.12; the bifurcation ratio is thus a decreasing function of dimensionality. This analysis also determines the scaling properties of the ramification matrix, which describes the hierarchy of branches.

Plasma resonance and remaining Josephson coupling in the ``decoupled vortex liquid phase'' in layered superconductors

description: We relate the frequency of the plasma resonance in layered superconductors with the frequency dependent superconducting response along the c-direction. We demonstrate that the sharp resonance can persist even when the global superconducting coherence in this direction is absent provided the resonance frequency is larger than the typical frequency of interlayer phase slips. In this situation the plasma frequency is determined by the average Josephson energy, which can be calculated using the high temperature expansion. We also find the temperature dependence of the average Josephson energy from the Monte Carlo simulations of the uniformly frustrated XY model and determine the applicability region of the high temperature expansion. The field and temperature scaling of the plasma frequency suggested by the high temperature expansion is consistent with experiment.

Mitigating the Sign Problem Through Basis Rotations

description: Quantum Monte Carlo simulations of quantum many body systems are plagued by the Fermion sign problem. The computational complexity of simulating Fermions scales exponentially in the projection time $β$ and system size. The sign problem is basis dependent and an improved basis, for fixed errors, lead to exponentially quicker simulations. We show how to use sign-free quantum Monte Carlo simulations to optimize over the choice of basis on large two-dimensional systems. We numerically illustrate these techniques decreasing the `badness' of the sign problem by optimizing over single-particle basis rotations on one and two-dimensional Hubbard systems. We find a generic rotation which improves the average sign of the Hubbard model for a wide range of $U$ and densities for $L \times 4$ systems. In one example improvement, the average sign (and hence simulation cost at fixed accuracy) for the $16\times 4$ Hubbard model at $U/t=4$ and $n=0.75$ increases by $\exp\left[8.64(6)β\right]$. For typical projection times of $β\gtrapprox 100$, this accelerates such simulation by many orders of magnitude.
