Fighting the flow: the stability of model flocks in a vortical flow

Subjects: subject: Biological Physics (physics.bio-ph)

description: We investigate the stability of self-propelled particle flocks in the Taylor-Green vortex, a steady vortical flow. We consider a model where particles align themselves to a combination of the orientation and the acceleration of particles within a critical radius. We identify two distinct regimes, if alignment with orientation is dominant the particles tend to be expelled from regions of high vorticity. In contrast if anticipation is dominant the particles accumulate in areas of large vorticity. In both regimes the relative order of the flock is reduced. However we show that there can be a critical balance of the two effects which stabilises the flock in the presence of external fluid forcing. This strategy could provide a mechanism for animal flocks to remain globally ordered in the presence of fluid forcing, and may also have applications in the design of flocking autonomous drones and artificial microswimmers.

description: It is found that nonlinear interaction of plasma wakefields driven by counterpropagating laser or particle beams can efficiently generate high-power electromagnetic radiation at the second harmonic of the plasma frequency. Using a simple analytical theory and particle-in-cell simulations, we show that this phenomenon can be attractive for producing high-field ($\sim 10$ MV/cm) narrowband terahertz pulses with the gigawatt power level and millijoule energy content.

description: This report summarises the participatory experiences in Critical Making, specifically in terms of defining and applying a new analytical framework, which we named “Critical Making Responsibility Framework” (CMRF). The document outlines the iterative approach the consortium took, which reflects the overall work of this project: starting from an academic proposal to combine Responsible Research and Innovation (RRI) principles (Tassone et al. 2018) with Grassroots Innovation Movement (GIM) framework (Smith et al. 2017) as first outlined in the project proposal, and (for now) resulting in an interactive online escape room game. We documented the winding – but highly collaborative – pathway through academic papers and conference presentations, one of which received a best paper award, or another one that proposed a new RRI key. We also had lengthy reflexive discussions with researchers from different disciplines, and held two workshops with, and got surveys filled out by our non-academic co-researchers, the critical makers. In this report, instead of repeating what we already communicated, the papers and other materials are collected with an overview, including a short reflection on their roles in the process. In the conclusion, the author summarises this reflexive and participatory experience and offers an outlook for future research.

description: The observed mass excesses of analog nuclear states with the same mass number $A$ and isospin $T$ can be used to test the isobaric multiplet mass equation (IMME), which has, in most cases, been validated to a high degree of precision. A recent measurement [Kankainen et al., Phys. Rev. C 93 041304(R) (2016)] of the ground-state mass of $^{31}$Cl led to a substantial breakdown of the IMME for the lowest $A = 31, T = 3/2$ quartet. The second-lowest $A = 31, T = 3/2$ quartet is not complete, due to uncertainties associated with the identity of the $^{31}$S member state. Using a fast $^{31}$Cl beam implanted into a plastic scintillator and a high-purity Ge $γ$-ray detection array, $γ$ rays from the $^{31}$Cl$(βγ)$$^{31}$S sequence were measured. Shell-model calculations using USDB and the recently-developed USDE interactions were performed for comparison. Isospin mixing between the $^{31}$S isobaric analog state (IAS) at 6279.0(6) keV and a nearby state at 6390.2(7) keV was observed. The second $T = 3/2$ state in $^{31}$S was observed at $E_x = 7050.0(8)$ keV. Isospin mixing in $^{31}$S does not by itself explain the IMME breakdown in the lowest quartet, but it likely points to similar isospin mixing in the mirror nucleus $^{31}$P, which would result in a perturbation of the $^{31}$P IAS energy. USDB and USDE calculations both predict candidate $^{31}$P states responsible for the mixing in the energy region slightly above $E_x = 6400$ keV. The second quartet has been completed thanks to the identification of the second $^{31}$S $T = 3/2$ state, and the IMME is validated in this quartet.
Knowledge Infrastructures: The Invisible Foundation of Research Data

Research Data

description: Implicit in investments in research data infrastructure is the assumption that data are valuable entities worth preserving, stewarding, sharing, and reusing. This value proposition also implies that research data are useful to others and that others will reuse those data. However, neither outcome is assured. Data practices are local, varying from field to field, individual to individual, and country to country. As the number and variety of research partners expands, so do the difficulties of sharing, reusing, and sustaining access to data. Efforts to develop global research infrastructures are hindered by communities’ lack of agreement on data management practices –or on what constitutes ‘research data.’ This talk argues for a broader focus on knowledge infrastructures, which are robust networks of people, artifacts, and institutions for producing, exchanging, and sustaining knowledge. Technical aspects of infrastructure, from persistent identifiers to compute capacity and storage, are easier to address than are social aspects, such as data stewardship, trust, governance, economics, infrastructure, standards, and science policy. Infrastructures can connect communities when they support local practices, and disconnect communities when they create incompatible silos. Examples are drawn from several decades of empirical research with research communities in environmental sciences, sensor networks, astronomy, biomedicine, social sciences, and digital humanities.
title: Optimisation of a weightless neural network using particle swarms
Creators: name: Hannan bin Azhar, M. A.
Publisher: name: University of Kent
Year: 2023

description: Among numerous pattern recognition methods the neural network approach has been the subject of much research due to its ability to learn from a given collection of representative examples. This thesis is concerned with the design of weightless neural networks, which decompose a given pattern into several sets of n points, termed n-tuples. Considerable research has shown that by optimising the input connection mapping of such n-tuple networks classification performance can be improved significantly. In this thesis the application of a population-based stochastic optimisation technique, known as Particle Swarm Optimisation (PSO), to the optimisation of the connectivity pattern of such “n-tuple” classifiers is explored. The research was aimed at improving the discriminating power of the classifier in recognising handwritten characters by exploiting more efficient learning strategies. The proposed "learning" scheme searches for ‘good’ input connections of the n-tuples in the solution space and shrinks the search area step by step. It refines its search by attracting the particles to positions with good solutions in an iterative manner. Every iteration the performance or fitness of each input connection is evaluated, so a reward and punishment based fitness function was modelled for the task. The original PSO was refined by combining it with other bio-inspired approaches like Self-Organized Criticality and Nearest Neighbour Interactions. The hybrid algorithms were adapted for the n-tuple system and the performance was measured in selecting better connectivity patterns. The Genetic Algorithm (GA) has been shown to be accomplishing the same goals as the PSO, so the performances and convergence properties of the GA were compared against the PSO to optimise input connections. Experiments were conducted to evaluate the proposed methods by applying the trained classifiers to recognise handprinted digits from a widely used database. Results revealed the superiority of the particle swarm optimised training for the n-tuples over other algorithms including the GA. Low particle velocity in PSO was favourable for exploring more areas in the solution space and resulted in better recognition rates. Use of hybridisation was helpful and one of the versions of the hybrid PSO was found to be the best performing algorithm in finding the optimum set of input maps for the n-tuple network.

description: The two-dimensional organic conductor $α$-(BEDT-TTF)$_2$I$_3$ undergoes a metal-insulator transition at $T_{\rm CO}=135$ K due to electronic charge ordering. We have conducted time-resolved investigations of its electronic properties in order to explore the field- and temperature-dependent dynamics. At a certain threshold field, the system switches from low-conducting to a high-conducting state, accompanied by a negative differential resistance. Our time-dependent infrared investigations indicate that close to $T_{\rm CO}$ the strong electric field pushes the crystal into a metallic state with optical properties similar to the one for $T>T_{\rm CO}$. Well into the insulating state, however, at $T=80$ K, the spectral response evidences a completely different electronically-induced high-conducting state. Applying a two-state model of hot electrons explains the observations by excitation of charge carriers with a high mobility. They resemble the Dirac-like charge-carriers with a linear dispersion of the electronic bands found in $α$-(BEDT-TTF)$_2$I$_3$ at high-pressure. Extensive numerical simulations quantitatively reproduce our experimental findings in all details.

description: Information transmission in biological signaling circuits has often been described using the metaphor of a noise filter. Cellular systems need accurate, real-time data about their environmental conditions, but the biochemical reaction networks that propagate, amplify, and process signals work with noisy representations of that data. Biology must implement strategies that not only filter the noise, but also predict the current state of the environment based on information delayed due to the finite speed of chemical signaling. The idea of a biochemical noise filter is actually more than just a metaphor: we describe recent work that has made an explicit mathematical connection between signaling fidelity in cellular circuits and the classic theories of optimal noise filtering and prediction that began with Wiener, Kolmogorov, Shannon, and Bode. This theoretical framework provides a versatile tool, allowing us to derive analytical bounds on the maximum mutual information between the environmental signal and the real-time estimate constructed by the system. It helps us understand how the structure of a biological network, and the response times of its components, influences the accuracy of that estimate. The theory also provides insights into how evolution may have tuned enzyme kinetic parameters and populations to optimize information transfer.

description: Metallic nanoparticles offer possibilities to build basic electric devices with new functionality and improved performance. Due to the small volume and the resulting low self-capacitance, each single nanoparticle exhibits a high charging energy. Thus, a Coulomb-energy gap emerges during transport experiments that can be shifted by electric fields, allowing for charge transport whenever energy levels of neighboring particles match. Hence, the state of the device changes sequentially between conducting and non-conducting instead of just one transition from conducting to pinch-off as in semiconductors. To exploit this behavior for field-effect transistors, it is necessary to use uniform nanoparticles in ordered arrays separated by well-defined tunnel barriers. In this work, CoPt nanoparticles with a narrow size distribution are synthesized by colloidal chemistry. These particles are deposited via the scalable Langmuir-Blodgett technique as ordered, homogeneous monolayers onto Si/SiO2 substrates with pre-patterned gold electrodes. The resulting nanoparticle arrays are limited to stripes of adjustable lengths and widths. In such a defined channel with a limited number of conduction paths the current can be controlled precisely by a gate voltage. Clearly pronounced Coulomb oscillations are observed up to temperatures of 150 K. Using such systems as field-effect transistors yields unprecedented oscillating current modulations with on/off-ratios of around 70 %.

description: Observations of coronal jets increasingly suggest that local fragmentation and intermittency play an important role in the dynamics of these events. In this work we investigate this fragmentation in high-resolution simulations of jets in the closed-field corona. We study two realizations of the embedded-bipole model, whereby impulsive helical outflows are driven by reconnection between twisted and untwisted field across the domed fan plane of a magnetic null. We find that the reconnection region fragments following the onset of a tearing-like instability, producing multiple magnetic null points and flux-rope structures within the current layer. The flux ropes formed within the weak-field region in the center of the current layer are associated with "blobs" of density enhancement that become filamentary threads as the flux ropes are ejected from the layer, whereupon new flux ropes form behind them. This repeated formation and ejection of flux ropes provides a natural explanation for the intermittent outflows, bright blobs of emission, and filamentary structure observed in some jets. Additional observational signatures of this process are discussed. Essentially all jet models invoke reconnection between regions of locally closed and locally open field as the jet-generation mechanism. Therefore, we suggest that this repeated tearing process should occur at the separatrix surface between the two flux systems in all jets. A schematic picture of tearing-mediated jet reconnection in three dimensions is outlined.

description: Shorter-dated options have become more popular in the grain and oilseeds markets. While they remain tied to (or derivatives on) the common underlying futures contracts, they have shorter tenor or maturity dates than the regular options that are typically listed for a year or more prior to expiration. The shortest common tenor are “weeklies”, so named because they have expiration dates for weeks that do not have regular nor serial options expiring, generally on Fridays, and they generally trade for three or four weeks. The value of weeklies can be lower than regular options because of the shorter tenor, and higher because of a volatility risk premium. Weeklies are touted as useful for positioning around major USDA reports. Empirically, this would be reflected in differences among the implied volatility, realized volatility and spot volatility of weeklies and regular options. The implied and realized volatility levels are higher in weeks that contain major USDA reports. The implied and spot volatility explain realized volatility, but at degrees that vary depending on the timespan considered. The results suggest that the weeklies contain information about short-run price behavior that is not fully explained by regular options.

description: Work life (WL) imbalance is common in different organizations as a result of which the work place is characterized by stress, lack of employees’ commitment, job dissatisfaction and over all dissatisfaction which leads to absenteeism, turnover and reduced performance coupled with lack of ownership and reluctance to serve customers. The major objective of this study is assessing work life balance (WLB) practices and its effects on employees’ performance in selected public institutions of federal government of Ethiopia. To this end raised and answered basic research questions that include, to what extent does WLB is practiced in the selected public institutions? What is the effect of WLB practices on employees’ performance? And what are the challenges of WLB and the possible recommendations for improvement in the selected public institution? The study used mixed research approach with descriptive and explanatory research designs. Primary data was collected from sample of 400 employees who are selected by using systematic random sampling technique from six public institutions (which are selected purposively). Proportionate stratified sampling was used to categorize the selected public institutions in to strata. Questionnaires and key informants interview and focused group discussion (FGD) were employed to collect the primary data. Accordingly the study found out that work roles interfere with other roles; lack of WLB policies and programs, employees are stressful and dissatisfied with their work and existence of gap in employees’ performance though customers were responded as they are satisfied with institutions service. It is found out that, WLB has perfect and positive relationship with employees’ performance. Study also revealed out that WLB practice statistically significant effect on employee performance. So, WLB is worth noting concept which has multiplier effects on human aspects of the organizations. As a result, considering WLB in human resource management system of public institution is paramount. Recognizing employees’ role out of work, creating awareness about WLB, modifying contents and contexts of job, developing WLB policies and programs, making adjustment on salary scale and focusing on equal payment for equal jobs are some recommendations forwarded.

title: “Doing Strategy” – A practice-based study of small- and large-scale phenomena in SMEs.
Creators: name: Eccleston, Helen
Publisher: name: University of Central Lancashire
Year: 2021

description: This research presents an in-depth analysis of strategy activities and practices that take place within small and medium size enterprises (SMEs) in the North West of England. Using components of Schatzki’s social practice theory the research explores how and why SME’s practise strategy. The research considers current practice-based strategy research and challenges to create a conceptual framework that applies a social practice theory to propose a perspective of strategising that emphasizes how local purposive action, guided by components of practice, can actually result in the unexpected emergence of a coherent and plausible strategy. This has been completed with a set of empirical longitudinal observations and supplementary interviews within nine SMEs, to provide an acutely attuned representation of the variety of ways in which predispositions of practice are acquired and expressed in different situations and time frames. The findings provide an account of four different ways of practising strategy in SMEs; Firm Frugality, Meaningful Relationships, Renowned Reputation and Guided Compliance. It shows how the owner-manager’s understanding of strategy informs and organises; the concerns that orient their work, the everyday practical coping actions taken, and the ongoing improvisations and adjustments made, by analysing them in relation to the mental organising principles of practice; rules, understandings and teleoaffective structures. It demonstrates there is an entwining between the activities and understandings which informs the practice of strategy. Finally, the findings show how strategy, as a consistent pattern of actions, emerge serendipitously from the synergistic interweaving of such local coping actions, the practice predispositions that underpin them and the positive unintended consequences that unexpectedly ensued. Thus, the research contributes to strategy research by proposing how unintended consequences of practical coping leads to strategy emergence that considers the actors' social embeddedness and reveal the dynamics of how this actually happens in practice. By using practice theory to investigate how SMEs “do” strategy this research has two main contributions to knowledge. First, it documents how the multitude of coping actions solidify inadvertently over time into a set of practice understandings that provides the basis for strategising, without deliberate intent. Secondly, it details how seemingly inconsequential micro actions taken in situ are guided by practice propagated predispositions that provide the patterned consistency which makes the inadvertent emergence of a coherent strategy possible. By demonstrating how the “doing” of strategy can produce tangible organisational outcomes, this research offers insight into reconciling the troublesome micro/macro distinction implied in strategy research.
Developing knowledge translation mechanisms to advance Public Mental Health as a complex public health priority
Creators: name: Stansfield, Judith
Publisher: name: Leeds Beckett University
Year: 2023

description: Public Mental Health remains an under-developed area of policy and research, attracting limited attention and resource. One explanation of this is the complexity of mental health as a public health priority; mental health is influenced by multiple socioeconomic and environmental factors interacting with psychological and biological processes; and many sectors and organisations have a role to play in improving the population’s mental health. This synthesis explores a body of work that has aimed to overcome this complexity barrier through conceptual and empirical research to build knowledge and capacity within the public health system. The knowledge translation work took place within a national public health agency in England and, as such, contributes knowledge on mechanisms for developing and implementing evidence within a complex policy environment. This policy-oriented research shaped a new national public mental health programme, contributed knowledge on mental health complexity and system approaches and produced original knowledge translation tools to advance mental health as a public health priority. In developing knowledge translation mechanisms to advance Public Mental Health as a complex public health priority I firstly explore three underpinning themes: public mental health theory and policy, the need for a complex system approach to public mental health, and the importance of knowledge translation to public mental health. I describe why the research was undertaken, what knowledge gaps it filled and provide critical reflection and discussion on concepts, limitations, and the overall contribution of the body of work to knowledge and what gaps remain.

description: We present a fast, direct and adaptive Poisson solver for complex two-dimensional geometries based on potential theory and fast multipole acceleration. More precisely, the solver relies on the standard decomposition of the solution as the sum of a volume integral to account for the source distribution and a layer potential to enforce the desired boundary condition. The volume integral is computed by applying the FMM on a square box that encloses the domain of interest. For the sake of efficiency and convergence acceleration, we first extend the source distribution (the right-hand side in the Poisson equation) to the enclosing box as a $C^0$ function using a fast, boundary integral-based method. We demonstrate on multiply connected domains with irregular boundaries that this continuous extension leads to high accuracy without excessive adaptive refinement near the boundary and, as a result, to an extremely efficient "black box" fast solver.

description: We show that the proper inclusion of soft reparameterization modes in the Sachdev-Ye-Kitaev model of $N$ randomly interacting Majorana fermions reduces its long-time behavior to that of Liouville quantum mechanics. As a result, all zero temperature correlation functions decay with the universal exponent $\propto τ^{-3/2}$ for times larger than the inverse single particle level spacing $τ\gg N\ln N$. In the particular case of the single particle Green function this behavior is manifestation of the zero-bias anomaly, or scaling in energy as $ε^{1/2}$. We also present exact diagonalization study supporting our conclusions.

description: In spam and malware detection, attackers exploit randomization to obfuscate malicious data and increase their chances of evading detection at test time; e.g., malware code is typically obfuscated using random strings or byte sequences to hide known exploits. Interestingly, randomization has also been proposed to improve security of learning algorithms against evasion attacks, as it results in hiding information about the classifier to the attacker. Recent work has proposed game-theoretical formulations to learn secure classifiers, by simulating different evasion attacks and modifying the classification function accordingly. However, both the classification function and the simulated data manipulations have been modeled in a deterministic manner, without accounting for any form of randomization. In this work, we overcome this limitation by proposing a randomized prediction game, namely, a non-cooperative game-theoretic formulation in which the classifier and the attacker make randomized strategy selections according to some probability distribution defined over the respective strategy set. We show that our approach allows one to improve the trade-off between attack detection and false alarms with respect to state-of-the-art secure classifiers, even against attacks that are different from those hypothesized during design, on application examples including handwritten digit recognition, spam and malware detection.

description: Intrinsic entanglement (IE) is a quantity which aims at quantifying bipartite entanglement carried by a quantum state as an optimal amount of the intrinsic information that can be extracted from the state by measurement. We investigate in detail the properties of a Gaussian version of IE, the so-called Gaussian intrinsic entanglement (GIE). We show explicitly how GIE simplifies to the mutual information of a distribution of outcomes of measurements on a conditional state obtained by a measurement on a purifying subsystem of the analyzed state, which is first minimized over all measurements on the purifying subsystem and then maximized over all measurements on the conditional state. By constructing for any separable Gaussian state a purification and a measurement on the purifying subsystem which projects the purification onto a product state, we prove that GIE vanishes on all Gaussian separable states. Via realization of quantum operations by teleportation, we further show that GIE is non-increasing under Gaussian local trace-preserving operations and classical communication. For pure Gaussian states and a reduction of the continuous-variable GHZ state, we calculate GIE analytically and we show that it is always equal to the Gaussian Rényi-2 entanglement. We also extend the analysis of IE to a non-Gaussian case by deriving an analytical lower bound on IE for a particular form of the non-Gaussian continuous-variable Werner state. Our results indicate that mapping of entanglement onto intrinsic information is capable of transmitting also quantitative properties of entanglement and that this property can be used for introduction of a quantifier of Gaussian entanglement which is a compromise between computable and physically meaningful entanglement quantifiers.

Speech Enhancement via Two-Stage Dual Tree Complex Wavelet Packet Transform with a Speech Presence Probability Estimator
Creators: name: Sun, Pengfei
name: Qin, Jun
Publisher: name: arXiv
Year: 2016
Subjects: subject: Sound (cs.SD)
subject: FOS: Computer and information sciences

description: In this paper, a two-stage dual tree complex wavelet packet transform (DTCWPT) based speech enhancement algorithm has been proposed, in which a speech presence probability (SPP) estimator and a generalized minimum mean squared error (MMSE) estimator are developed. To overcome the drawback of signal distortions caused by down sampling of WPT, a two-stage analytic decomposition concatenating undecimated WPT (UWPT) and decimated WPT is employed. An SPP estimator in the DTCWPT domain is derived based on a generalized Gamma distribution of speech, and Gaussian noise assumption. The validation results show that the proposed algorithm can obtain enhanced perceptual evaluation of speech quality (PESQ), and segmental signal-to-noise ratio (SegSNR) at low SNR nonstationary noise, compared with other four state-of-the-art speech enhancement algorithms, including optimally modified LSA (OM-LSA), soft masking using a posteriori SNR uncertainty (SMPO), a posteriori SPP based MMSE estimation (MMSE-SPP), and adaptive Bayesian wavelet thresholding (BWT).

Algorithms and analyses for stochastic optimization for turbofan noise reduction using parallel reduced-order modeling
Creators: name: Yang, Huanhuan
name: Gunzburger, Max
Publisher: name: arXiv
Year: 2016
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: Simulation-based optimization of acoustic liner design in a turbofan engine nacelle for noise reduction purposes can dramatically reduce the cost and time needed for experimental designs. Because uncertainties are inevitable in the design process, a stochastic optimization algorithm is posed based on the conditional value-at-risk measure so that an ideal acoustic liner impedance is determined that is robust in the presence of uncertainties. A parallel reduced-order modeling framework is developed that dramatically improves the computational efficiency of the stochastic optimization solver for a realistic nacelle geometry. The reduced stochastic optimization solver takes less than 500 seconds to execute. In addition, well-posedness and finite element error analyses of the state system and optimization problem are provided.

description: CSI-COP, a citizen science project responding to the Horizon2020 research and innovation (RIA) grant call in the theme science with and for society (SwafS) under the topic ‘Exploring and Supporting Citizen Science’, is the first of its kind investigating websites and apps for compliance with a new EU regulation: the general data protection regulations (GDPR). With six specific objectives, six milestones and six expected impacts, the project realised its research and innovation goals through its outputs. These included production of a classification of the different types of website and app cookies and other online tracking tools (CSI-COP Taxonomy), and the innovation of a searchable open-access web knowledge base of websites and apps investigated by the project’s citizen scientists and researchers (CSI-COP Repository). This document presents a synthesis of CSI-COP project activities and results to raise awareness of rights accorded in the GDPR, and the investigations of GDPR compliance in websites and apps by citizen scientists and the project researchers. CSI-COP legacy includes forming a post-project forum with the project’s Privacy Champions who emerged from the project’s citizen scientists. The long-term legacy aims to continue raising the project’s message. Additionally, CSI-COP’s post-project activity will raise awareness of the EU’s Digital Services Act, and the risks to personal data from artificial intelligence (AI) tools such as large language models (LLMs), for example OpenAI-Microsoft’s ChatGPT, and Google’s BARD now applied as answer-summarisers in evolved browser-search. The long-term aim is contributing to the creation of effective standards for website and app cookie notices and privacy policies, and beyond that, in Internet-connected devices in the home and transportation.
