description: We investigate the effects of long-range social interactions in flocking dynamics by studying the dynamics of a scalar model of collective motion embedded in a complex network representing a pattern of social interactions, as observed in several social species. In this scalar model we find a phenomenology analogous to that observed in the classic Vicsek model: In networks with low heterogeneity, a phase transition separates an ordered from a disordered phase. At high levels of heterogeneity, instead, the transition is suppressed and the system is always ordered. This observation is backed up analytically by the solution of a modified scalar model within an heterogeneous mean-field approximation. Our work extends the understanding of the effects of social interactions in flocking dynamics and opens the path to the analytical study of more complex topologies of social ties.

description: Based on Bbar to D{(*)}K-K{*0} decay data, which supports factorization, we propose to extract the kaon axial form factor in the factorization framework. Experiment indicates that the K-K{*0} pair is produced by an axial current where only one out of three axial form factors is dominant. The axial form factor can be extracted by fitting the K-K{*0} mass spectrum with an a_1(1260)-resonance plus QCD-motivated non-resonant contributions, which can be improved as data improves.

Stable discretisations of high-order discontinuous Galerkin methods on equidistant and scattered points

Subjects: subject: Numerical Analysis (math.NA)

description: In this work, we propose and investigate stable high-order collocation-type discretisations of the discontinuous Galerkin method on equidistant and scattered collocation points. We do so by incorporating the concept of discrete least squares into the discontinuous Galerkin framework. Discrete least squares approximations allow us to construct stable and high-order accurate approximations on arbitrary collocation points, while discrete least squares quadrature rules allow us their stable and exact numerical integration. Both methods are computed efficiently by using bases of discrete orthogonal polynomials. Thus, the proposed discretisation generalises known classes of discretisations of the discontinuous Galerkin method, such as the discontinuous Galerkin collocation spectral element method. We are able to prove conservation and linear $L^2$-stability of the proposed discretisations. Finally, numerical tests investigate their accuracy and demonstrate their extension to nonlinear conservation laws, systems, longtime simulations, and a variable coefficient problem in two space dimensions.

description: This thesis evaluates the connections between rural walking, modernity, and preservationism in late nineteenth- and early twentieth-century Britain. During this period, the expressed practices of rural walking were overt responses to change. Adherents of rural walking used this bipedal gesture to limit the latitude of efficiency, espouse collectivism, remedy prevailing illnesses, participate in modern applications of empiricism, and overcome contemporary spiritual challenges. They also indicated that engagement with undeveloped areas was fundamental to the benefits and functions of walking. Due to this interconnection of walking with a particular type of environment, the reasons why walkers walked fortified justifications for preserving rural environments. Although walking is an activity that has long been used to engage the natural world, its ubiquity as an everyday movement of the body has resulted in its under-representation in historical inquiry. This intellectual-environmental history demonstrates that much can be discovered about human relationships with rural environments, and efforts to preserve them, by evaluating walking historically.

description: This paper is intended as a re-reading of the fundamental concepts of the Information Structure (SI), through which we highlight the different partitions (at least the most obvious in our opinion), which involve binary articulations between closely related concepts relating to both discursive and pragmatic data such as "Topic", "Focus", "Background", "Presupposition", "predication", "given", "new", etc. in the construction of the IS . We will then try to bring these partitions closer to the phenomenon of protrusion through the process of activation of informational elements in the management of the Common Informational Fund (FIC), which allows us to distinguish between "referential salience" and "discursive salience".

description: We calculate the out-of-time-ordered correlation function (OTOC) of a single impurity qubit coupled to fully a connected many-particle system such as a bosonic Josephson junction or spins with long-range interactions. In these systems the qubit OTOC can be used to detect both ground state and excited state quantum phase transitions (QPTs), making it a robust order parameter that is considerably more sensitive than the standard one-body correlation function. Finite size scaling exponents for an $N$ body system can also be accurately extracted from the long-time OTOC dynamics, however, for short times there is a discrepancy due to the fact that the qubit has not had enough time to couple to the larger system. Our results show that the OTOC of even the smallest probe is enough to diagnose a QPT in fully connected models but, like a continuous measurement, can still cause a backaction effect which leads to weakly chaotic dynamics and gradual information scrambling.

description: The growth of large scale structure is studied in a universe containing both cold dark matter (CDM) and generalized Chaplygin gas (GCg). GCg is assumed to contribute only to the background evolution of the universe while the CDM component collapses and forms structures. We present some new analytical as well as numerical results for linear and non-linear growth in such model. The model passes the standard cosmological distance test without the need of a cosmological constant (LCDM). But we find that the scenario is severely constrained by current observations of large scale structure. Any small deviations of the GCg parameters away from the standard Lambda dominated cosmology (LCDM) produces substantial suppression for the growth of structures.

description: The evidence to date on the links between nutrition –sensitive agricultural interventions and dietary diversity has been scant and inconclusive. This study contributes to the debate by analyzing the impacts of sweet potato production on dietary diversity of farm households in northern Ethiopia. Survey data collected in 2014 from 524 sample households was used in the analysis. Endogenous switching regression model supported by binary propensity score matching methods were used to empirically assess the impact of adopting sweet potato on food consumption score or dietary diversity of farm households. Results show that education of household head, farm size, access to information, extension visit, and institutional services are the major determinants of household decisions to adopt sweet potato. The average treatment effect results also show that the food consumption score or dietary diversity is high for adopters as compared to the non-adopter counterparts. The results are robust and consistent in both methods. Thus, policies and development strategies encouraging further adoption of nutrition sensitive agricultural technologies could enhance dietary diversity of smallholder farmers in Ethiopia.

The crucial ingredient is the scaling law between the sphaleron energy at the temperature of the phase transition and that at zero temperature. We estimate the baryon number preservation criterion, and observe that for a sufficiently strong phase transition, it is possible to probe the electroweak sphaleron using measurements of future space-based gravitational wave detectors.

description: The study examined the labour supply-demand gap and farm mechanization as a coping mechanism to labour shortage in Northern and Southern Dry Zone of Karnataka, India. Based on the extent of net irrigated area under canal which is a proxy for greater degree of mechanization, Sindhanur taluk of Raichur district and Mandya taluk of Mandya district were selected for the study. The results revealed that the labour requirement was more in case of partially mechanized farm compared to that of mechanized farms. The mechanization of agricultural operations has saved labour use to a certain proportion compared to partially mechanized farm, which was around 20 per cent in paddy, 13-15 per cent in ragi, jowar and bengalgram. The labour demand exceeded labour supply during the months of July and December in Sindhanur taluk while it was during December and October in Mandya taluk highlighting the seriousness of labour scarcity. The results also indicated that the mechanization helps to cope-up with labour shortages particularly during the peak seasons.
title: Targeting and regulation of protein import in the mitochondrial intermembrane space

Subjects: subject: Mitochondria, redox, intermembrane, space, reactive, oxygen, species.

description: Mitochondria are organelles that are vital for cellular metabolism. For the mitochondrion’s various metabolic processes to proceed, proteins are required to venture from the nucleus to the organelle, as around 99% of mitochondrial proteins are produced in the nucleus. As such, mitochondria have incorporated distinct pathways to allow for protein insertion into their various compartments. These include insertion into the outer membrane (OM), the inner membrane (IM), the mitochondrial matrix (innermost compartment) and the mitochondrial intermembrane space (IMS, via the oxidative folding MIA pathway). It is often found that cytosolic proteins can be dually localised into other cellular compartments. This can also be said for proteins found within the mitochondrial intermembrane space, and is often a result of an alternative translation of the protein to include a peptide sequence that drives its translocation to a separate compartment. In this thesis, we studied the mechanisms by which a cytosolic enzyme known as Gpx3 is able to translocate to the mitochondrial intermembrane space to effectively combat reactive oxygen species (ROS) production in partnership with Mia40 (the major IMS oxidative folding protein). Through analysis of the radiolabelled protein import of the N-terminal extension of Gpx3 (named N18) into isolated mitochondria, we were able to analyse the energetic requirements for import and how the targeting information of the peptide is decoded by the outer membrane translocon system. The second part of the thesis focused on another IMS-localised cytosolic reductive system known as the thioredoxin (Trx) system. Recently discovered in the IMS, Trx1 works with TrR1 to recycle MIA from an unbalanced oxidised state to its balanced oxidising and reducing state. Here, we looked at reintroducing the IMS Trx system into mitochondria lacking the system (ΔTrx1/2) and observing for changes in oxidative damage and complex formation. Excitingly, we found that rescue of the IMS Trx system in turn rescues the formation of Tim9 complexes, suggesting the Trx system is crucial in maintaining the MIA pathway and thus maintains an optimal protein folding environment within the mitochondrial IMS.
Capabilities of bisector analysis of the Si I 10827 A line for estimating line-of-sight velocities in the quiet Sun

description: We examine the capabilities of a fast and simple method to infer line-of-sight (LOS) velocities from observations of the photospheric Si I 10827 A line. This spectral line is routinely observed together with the chromospheric He I 10830 A triplet as it helps to constrain the atmospheric parameters. We study the accuracy of bisector analysis and a line core fit of Si I 10827 A. We employ synthetic profiles starting from the Bifrost enhanced network simulation. The profiles are computed solving the radiative transfer equation, including non-local thermodynamic equilibrium effects on the determination of the atomic level populations of Si I. We found a good correlation between the inferred velocities from bisectors taken at different line profile intensities and the original simulation velocity at given optical depths. This good correlation means that we can associate bisectors taken at different line-profile percentages with atmospheric layers that linearly increase as we scan lower spectral line intensities. We also determined that a fit to the line-core intensity is robust and reliable, providing information about atmospheric layers that are above those accessible through bisectors. Therefore, by combining both methods on the Si I 10827 A line, we can seamlessly trace the quiet-Sun LOS velocity stratification from the deep photosphere to higher layers until around $\log τ= -3.5$ in a fast and straightforward way. This method is ideal for generating quick-look reference images for future missions like the Daniel K. Inoue Solar Telescope and the European Solar Telescope, for example.

description: Using panel data sourced from World Development Indicators, FAOSTAT and World Governance Indicators covering 15 countries from 1996-2015, we employ both the dynamic (System and difference generalized method of moments-GMM) and static (OLS, random effects, fixed effects) models to investigates the growth effects of African migration proxy as remittance and quality of governance on food and nutritional security in SSA. The empirical results from both models show that an increase in remittances and combined index of quality of governance in SSA contributes positively and significantly to all measures of food security vis-à-vis nutritional security considered in the study. In specific, the rule of law, government effectiveness, regulatory quality, political instability, and voice and accountability were found to influence the food security of SSA. However, the control over corruption has more impact on food security in the continent compared to other indicators. Accordingly, we contend that policies geared towards increasing government investment on curbing corruption which has been circumventing livelihood outcomes such as food and nutritional security over the years would likely raise economic growth and subsequently food and nutritional security levels in the region.

description: Water is a key resource to agriculture in Mendoza but there are increasing concerns regarding the viability of current practices and availability. Some farms fall short of their production potential, which questions the economic viability of some vineyards, and might trigger structural change and lead to additional pressure on water use. Improvements in irrigation efficiency could help mitigate this problem. Farmers pay for the resource management but do not have to consider the opportunity cost of the resource itself. This paper estimates the technical efficiency (TE) of grapevine production controling for the use of water. The preliminary results point out average efficiency scores of 0.78, where relatively efficient farmers lack proper management practices on water resources. Further estimation of the intrinsic value of irrigation water will provide an additional tool to design specific policies for the sector.

Tailoring Staircase-like Hysteresis Loops in Electrodeposited Trisegmented Magnetic Nanowires: a Strategy toward Minimization of Interwire Interactions
Creators: name: Zhang, Jin
Publisher: name: Zenodo
Year: 2016

description: A new strategy to minimize magnetic interactions between nanowires (NWs) dispersed in a fluid is proposed. Such a strategy consists of preparing trisegmented NWs containing two antiparallel ferromagnetic segments with dissimilar coercivity separated by a nonmagnetic spacer. The trisegmented NWs exhibit a staircase-like hysteresis loop with tunable shape that depends on the relative length of the soft- and hard-magnetic segments and the respective values of saturation magnetization. Such NWs are prepared by electrodepositing CoPt/Cu/Ni in a polycarbonate (PC) membrane. The antiparallel alignment is set by applying suitable magnetic fields while the NWs are still embedded in the PC membrane. Analytic calculations are used to demonstrate that the interaction magnetic energy from fully compensated trisegmented NWs with antiparallel alignment is reduced compared to a single-component NW with the same length or the trisegmented NWs with the two ferromagnetic counterparts parallel to each other. The proposed approach is appealing for the use of magnetic NWs in certain biological or catalytic applications where the aggregation of NWs is detrimental for optimized performance.

description: Despite goal four of Millennium Development Goals (MDGs) targets set by the United Nations for the nations of the world to reduce child mortality to its half by 2015, Nigerian children are still greatly affected by the incidence of poverty. We focus on the social attributes of the local area to assess what the geographic place represents. Using spatial error regression techniques to analyze Geopolitical Zone census data from Demographic Health Survey and National Living Standard Survey, we examined spatial differentiation in the relationships that generate child poverty and further explore their determining factors. Child poverty was found to be more prominent in the Northern region of the country. However, results from the analysis also established that there is a spillover of child poverty existed among the GPZs. While social and economic factors that influence the probability of child poverty varied across difference Geopolitical Zones (GPZs). Poverty incidence in a GPZ influenced the neighboring GPZ. Results also showed that local-area processes are at play with implications for more nuanced theoretical models and anti-child poverty policies that consider systematic differences in factors contributing to child poverty according to the social, infrastructural, agro ecological and economic contexts.

We explore the regional differences of the NRPS effect on labor supply between the West and non-West regions of China. Our analysis shows that western rural China has a more severe problem of “ceaseless toil” compared to the rest of the country. We find that NRPS improves the “ceaseless toil” situation of the Chinese rural elderly but the results show a very different pattern between western China and other part of the country.

description: Many biological and synthetic materials self-assemble into helical or twisted aggregates. The shape is determined by a complex interplay between elastic forces and the orientation and chirality of the constituent molecules. We study this interplay through Monte Carlo simulations, with an accelerated algorithm motivated by the growth of an aggregate out of solution. The simulations show that the curvature changes smoothly from cylindrical to saddle-like as the elastic moduli are varied. Remarkably, aggregates of either handedness form from molecules of a single handedness, depending on the molecular orientation.

description: This paper estimates the impacts of pesticide maximum residue level (MRL) standards imposed by the European Union (EU) on trade-flows from African exporting countries to the United Kingdom (UK) using a fixed-effects gravity model specification with corrections for the zero trade-flows. We employ the Poison Pseudo Maximum Likelihood (PPML) estimation method to estimate the gravity model. Most variables have the expected signs and were statistically significant, consistent with the trade literature. The volume of trade increases with the GDP of the exporting countries and the UK. The volume of trade decreases with geographical distance. The variables describing cultural and economic proximity of countries, such as colonial relationships positively affect the volume of trade. Regarding the impact of MLRs on trade flows, the results were not completely consistent between the product groups. However, some commodities do exhibit sensitivity to changes in pesticide MRL standards imposed by the EU and hence applied in the UK.
ChronoRAG : Detecting Events from Emails using Time-based Retrieval for RAG

Subjects: subject: Machine learning

description: Nowadays, a lot of decision-making occurs through email communication and online meetings. A project plan might change over time and the final deliverable might look different than what was planned during the starting phase of the project. These changes might be a result of multiple events which lead to different decisions and plans. Post-project retrospectives often require understanding the guiding factors behind these decisions, the timing of each decision, and the events that triggered them. This involves a time-based analysis of internal documents, email communications, meeting notes, and other data points pertaining to the project.

 

We demonstrate a time-based retrieval approach for RAG(Retrieval Augmented Generation) to detect events from a massive textual knowledge base. RAG has proven to be the technique for enhancing the accuracy and reliability of LLM-generated responses with facts fetched from external sources [1]. Without RAG, the LLM takes the user input and creates a response based on information it was trained on—or what it already knows. With RAG, an information retrieval component is introduced that utilizes the user input to first pull information from a given data source. The user query and the relevant information are both given to the LLM. The LLM uses the new knowledge and its training data to create better responses [2]. A simple retrieval approach retrieves data that are most semantically similar to a given user query. The time-based retrieval approach retrieves data that are semantically most similar and pertinent to a specific time frame. In time-based retrieval for RAG, time filtering is done before performing semantic similarity. Data that match the time filter are used for semantic retrieval. 

 

We used Qdrant [3] for our knowledge store and LangChain [4] framework to implement document ingestion, prompt management, and RAG. The knowledge store included emails, internal documents, meeting transcripts, and in-depth interviews of team members. After some data cleaning, the email data was divided into weeks (“week 1” to “week 100”) to track weekly changes. To track the decision changes and events, we used a chained RAG approach, wherein RAG was first applied to “week 1”  and the responses were used as context for RAG with a filter for “week 2”. To classify the events and to extract the entities from the events, we use Marvin[5]. In this poster, we will present the architecture used to track events from email data leveraging time-based retrieval for RAG.

Modelling of the turbulent burning velocity based on Lagrangian statistics of propagating surfaces

description: We propose a predictive model of the turbulent burning velocity $S_T$ in homogeneous isotropic turbulence (HIT) based on Lagrangian statistics of propagating surfaces. The propagating surfaces with a constant displacement speed are initially arranged on a plane, and they evolve in non-reacting HIT, behaving like the propagation of a planar premixed flame front. The universal constants in the model of $S_T$ characterize the enhancement of area growth of premixed flames by turbulence, and they are determined by Lagrangian statistics of propagating surfaces. The flame area is then modelled by the area of propagating surfaces at a truncation time. This truncation time signals the statistical stationary state of the evolutionary geometry of propagating surfaces, and it is modelled by an explicit expression using limiting conditions of very weak and strong turbulence. Another parameter in the model of $S_T$ characterizes the effect of fuel chemistry on $S_T$, and it is pre-determined by very few available data points of $S_T$ from experiments or direct numerical simulation (DNS) in weak turbulence. The proposed model is validated using three DNS series of turbulent premixed flames with various fuels. The model prediction of $S_T$ generally agrees well with DNS in a wide range of premixed combustion regimes, and it captures the basic trends of $S_T$ in terms of the turbulence intensity, including the linear growth in weak turbulence and the `bending effect' in strong turbulence.

Longitudinal Bird strike monitoring : UBC Buchanan Building

description: Bird-window collisions are the second leading cause of bird fatalities in the United States, accounting for billions of deaths each year. This study aimed to determine how many bird-window collisions occurred at the University of British Columbia's Buchanan complex, using a modified methodology created by Hager and Cosentino ( 2014). We collected data and surveyed for eight weeks and found evidence of at least thirty-three bird-window collisions. The buildings that accounted for the most collisions were Buchanan A, C and D, specifically facades twenty-five, thirteen, and ten. Contributing factors that make these facades the most problematic include the presence of vegetation. We also found that our results this year were similar to last year. However, there were critical differences in collision types and which facades accounted for collisions. Future management solutions would include applying the feather-friendly decal to Buchanan C, facade thirteen, as it was responsible for the most significant number of collisions.

Assessing the neurocognitive correlates of resting brain entropy

description: The human brain exhibits large-scale spontaneous fluctuations that account for most of its total energy metabolism. Independent of any overt function, this immense ongoing activity likely creates or maintains a potential functional brain reserve to facilitate normal brain function. An important property of spontaneous brain activity is the long-range temporal coherence, which can be characterized by resting state fMRI-based brain entropy mapping (BEN), a relatively new method that has gained increasing research interest. The purpose of this study was to leverage the large resting state fMRI and behavioral data publicly available from the human connectome project to address three important but still unknown questions: temporal stability of rsfMRI-derived BEN; the relationship of resting BEN to latent functional reserve; associations of resting BEN to neurocognition. Our results showed that rsfMRI-derived BEN was highly stable across time; resting BEN in the default mode network (DMN) and executive control network (ECN) was related to brain reserve in a negative correlation to education years; and lower DMN/ECN BEN corresponds to higher fluid intelligence and better task performance. These results suggest that resting BEN is a temporally stable brain trait; BEN in DMN/ECN may provide a means to measure the latent functional reserve that bestows better brain functionality and may be enhanced by education.
