description: The classical Gill's stability problem for the stationary and parallel buoyant flow in a vertical porous slab with impermeable and isothermal boundaries kept at different temperatures is reconsidered in a different perspective. A three-layer slab is studied instead of a homogeneous slab as in Gill's problem. The three layers have a symmetric configuration where the two external layers have a high thermal conductivity, while the core layer has a much lower conductivity. A simplified model is set up where the thermal conductivity ratio between the external layers and the internal core is assumed as infinite. It is shown that a flow instability in the sandwiched porous slab may arise with a sufficiently large Rayleigh number. It is also demonstrated that this instability coincides with that predicted in a previous analysis for a homogeneous porous layer with permeable boundaries, by considering the limiting case where the permeability of the external layers is much larger than that of the core layer.

description: Damage detection and localization is a critical task of structural health monitoring. Artificial Neural Network (ANN) have been successfully applied for damage identification in civil and mechanical structures presenting some limitations. However, it is possible to improve the effectiveness of ANNs by modifying their architecture and training strategies. The present paper proposes a metaheuristic algorithm, in particular, Butterfly Optimization Algorithm (BOA) to create an optimum ANN for multiple damage prediction in aluminum bar. Natural frequencies are used as input parameters and crack depths as output. Based on different crack depths, an improved Finite Element Model (FEM) is used to collect data using simulation tool. In order to test the reliability of the presented technique, experimental data from cracked beam analysis is collected based on different crack depths. The results are compared to other similar approaches using metaheuristic algorithms, namely, Artificial Bee Colony Algorithm (ABC) and Genetic Algorithm (GA). The novel proposed approach present a good performance for damage prediction.

description: In industrial societies, women increasingly postpone motherhood. While men do not fear a loss of fertility with age, women face the biological boundary of menopause. The freezing of unfertilized eggs can overcome this biological barrier. Due to technical improvements in vitrification, so-called “social freezing” (SF) for healthy women is likely to develop into clinical routine. Controversial ethical debates focus on the risks of the technique for mother and child, the scope of reproductive autonomy, and the medicalization of reproduction. Some criticize the use of the technique in healthy women in general, while others support a legally defined maximum age for women at the time of an embryo transfer after oocyte cryopreservation. Since this represents a serious encroachment on the reproductive autonomy of the affected women, the reasons for and against must be carefully examined. We analyze arguments for and against SF from a gendered ethical perspective. We show that the risk of the cryopreservation of oocytes for mother and future child is minimal and that the autonomy of the women involved is not compromised. The negative ethical evaluation of postponed motherhood is partly due to a biased approach highlighting only the medical risks for the female body without recognizing the potential positive effects for the women involved. In critical accounts, age is associated in an undifferentiated way with morbidity and psychological instability and is thus used in a discriminatory way. We come to the conclusion that age as a predictor of risk in the debate about SF is, from an ethical point of view, an empty concept based on gender stereotypes and discriminatory connotations of aging. A ban on postponing motherhood via SF is not justified.

Development and mechanical characterisation of additively manufactured lattice structures
Creators: name: Lee, James Jiyung
Publisher: name: Imperial College London
Year: 2022

description: Lightweight, energy-absorbing structures are needed in many areas where the protection and threat mitigation of fragile personnel and objects are essential. Hence, the investigation of development and characterisation of energy-absorbing materials are crucial. The recent advances in the additive manufacturing (AM) have enhanced the development of such structures in many aspects with precisely designed configurations of the internal structures. Given the range of potential materials, many possible variations exist compared to the traditional polymer-based foams. The advantages of rapid prototyping, enabled through AM, allows a streamlined design process in obtaining a structure of mechanical behaviour suitable for intended applications. In this work, the development and fabrication of a flexible polymer-based lattice structure with core strut variations are demonstrated. A re-entrant honeycomb unit cell based lattice structure is chosen in a sandwich configuration with the implementation and modification of core struts for further investigation. The designed lattices are fabricated using stereolithography (SLA), a type of vat photopolymerisation, utilising the Formlabs Flexible 80A® resin. The core struts are modified in terms of shape, density and number of inclusions within the internal structure of the lattice. The mechanical characterisation of the samples under uniaxial compression is carried out at the strain rates of 0.005, 0.9 and 108 s-1 and the appropriate experimental apparatus and the diagnostics are developed and used for this purpose. The stress-strain responses reveal that the variations in the core struts affect the overall deformation behaviour of the structure, as well as the strain rate dependence of the relevant mechanical parameters. Anisotropic nature of the lattices are also investigated by uni-axial compression of the lattices positioned at 45◦ and 90◦ angles. The theoretically obtained parameters, from the formulations only dependent on the relative density, and the parameters calculated from the measured values are evaluated and compared, providing the insight that the the structural geometries influence the characteristic behaviour of the lattices over relative density or the material, highlighting the significance of the chosen structural design of the lattices. Finally, the discussion of the research findings in terms of the recommended applications of the each sample type, the functional flexibility and adaptability are presented.

description: In 1+1-dimensional conformal field theory, the thermal state on a circle is related to a certain quotient of the vacuum on a line. We explain how to take this quotient in the MERA tensor network representation of the vacuum and confirm the validity of the construction in the critical Ising model. This result suggests that the tensors comprising MERA can be interpreted as performing local scale transformations, so that adding or removing them emulates conformal maps. In this sense, the optimized MERA recovers local conformal invariance, which is explicitly broken by the choice of lattice. Our discussion also informs the dialogue between tensor networks and holographic duality.

description: Objective: We examined trends from 1991- 2009 in total energy intake and food group intake, and examine whether shifts varied by age or generation. Design: Longitudinal time series (1991, 1993, 1997, 2000, 2004, 2006, 2009) Setting: Nine provinces in China Participants: Older Chinese aged ≥60 years (n=5,068) from the China Health and Nutrition Survey from 1991-2009 Methods: Using three 24-hour recalls and a household food inventory collected over three consecutive days, the top twenty food group contributors to total energy intake from 1991- 2009 were identified, and the mean kilocalorie (kcal) difference between 1991 and 2009 for each food group was ranked. The top twenty food group contributors to total energy intake from 1991- 2009 were identified, and the mean kilocalorie (kcal) difference between 1991 and 2009 for each food group was ranked. Linear regression was used to examine changes in mean calorie intake of food groups between 1991 and 2009, adjusting for age, sex, and region. In addition, we examined changes in the mean kcal per capita intake to examine shifts by age group and generation. Results: Mean total energy intake increased significantly among older Chinese adults from 1379 total kilocalories in 1991 to 1463 kilocalories in 2009 (p< 0.001). Most food groups showed a significant increase in intake from 1991 to 2009, with plant oil, wheat buns, and wheat noodles showing the greatest increase. At the same age, more recent generations had more energy intake than earlier generations. An aging effect was observed, with energy intake decreasing with age, although more recent generations showed a smaller decrease in energy intake with aging. Conclusion: Older Chinese adults in recent generations show an increase in total calorie intake compared to older Chinese of earlier generations, paired with a less significant decrease in calorie intake as they age. Increased consumption of high-fat, non-staple high-carbohydrate foods such as plant oil and wheat buns suggests that diet quality of older Chinese adults is becoming less healthful in recent years.

description: Graph neural networks (GNNs), which are capable of learning representations from graphical data, are naturally suitable for modeling molecular systems. This review introduces GNNs and their various applications for small organic molecules. GNNs rely on message-passing operations, a generic yet powerful framework, to update node features iteratively. Many researches design GNN architectures to effectively learn topological information of 2D molecule graphs as well as geometric information of 3D molecular systems. GNNs have been implemented in a wide variety of molecular applications, including molecular property prediction, molecular scoring and docking, molecular optimization and de novo generation, molecular dynamics simulation, etc. Besides, the review also summarizes the recent development of self-supervised learning for molecules with GNNs.

description: Microbial surfactants are particularly useful in bioremediation and heavy metal removal from soil and aquatic environments, amongst other highly valued uses in different economic and biomedical sectors. Marine sponge-associated bacteria are well-known producers of bioactive compounds with a wide array of potential applications. However, little progress has been made on investigating biosurfactants produced by these bacteria, especially when compared with other groups of biologically active molecules harnessed from the sponge microbiome. Using a thorough literature search in eight databases, the purpose of the review was to compile the current knowledge on biosurfactants from sponge-associated bacteria, with a focus on their relevant biotechnological applications. From the publications between the years 1995 and 2021, lipopeptides and glycolipids were the most identified chemical classes of biosurfactants. Firmicutes was the dominant phylum of biosurfactant-producing strains, followed by Actinobacteria and Proteobacteria. Bioremediation led as the most promising application field for the studied surface-active molecules in sponge-derived bacteria, despite the reports endorsed their use as antimicrobial and antibiofilm agents. Finally, we appoint some key strategies to instigate the research appetite on the isolation and characterization of novel biosurfactants from the poriferan microbiome.

description: Recent Wave Energy Converters (WEC) are equipped with multiple legs and generators to maximize energy generation. Traditional controllers have shown limitations to capture complex wave patterns and the controllers must efficiently maximize the energy capture. This paper introduces a Multi-Agent Reinforcement Learning controller (MARL), which outperforms the traditionally used spring damper controller. Our initial studies show that the complex nature of problems makes it hard for training to converge. Hence, we propose a novel skip training approach which enables the MARL training to overcome performance saturation and converge to more optimum controllers compared to default MARL training, boosting power generation. We also present another novel hybrid training initialization (STHTI) approach, where the individual agents of the MARL controllers can be initially trained against the baseline Spring Damper (SD) controller individually and then be trained one agent at a time or all together in future iterations to accelerate convergence. We achieved double-digit gains in energy efficiency over the baseline Spring Damper controller with the proposed MARL controllers using the Asynchronous Advantage Actor-Critic (A3C) algorithm.

description: We compute the isospin-asymmetry dependence of microscopic optical model potentials from realistic chiral two- and three-body interactions over a range of resolution scales $Λ\simeq 400-500$\,MeV. We show that at moderate projectile energies, $E_{\rm inv} = 110 - 200$\,MeV, the real isovector part of the optical potential changes sign, a phenomenon referred to as isospin inversion. We also extract the strength and energy dependence of the imaginary isovector optical potential and find no evidence for an analogous phenomenon over the range of energies, $E \leq 200$\,MeV, considered in the present work. Finally, we compute for the first time the leading corrections to the Lane parametrization for the isospin-asymmetry dependence of the optical potential and observe an enhanced importance at low scattering energies.

description: Active galactic nuclei (AGN) are complex phenomena. At the heart of an AGN is a relativistic accretion disk around a spinning supermassive black hole (SMBH) with an X-ray emitting corona and, sometimes, a relativistic jet. On larger scales, the outer accretion disk and molecular torus act as the reservoirs of gas for the continuing AGN activity. And on all scales from the black hole outwards, powerful winds are seen that probably affect the evolution of the host galaxy as well as regulate the feeding of the AGN itself. In this review article, we discuss how X-ray spectroscopy can be used to study each of these components. We highlight how recent measurements of the high-energy cutoff in the X-ray continuum by NuSTAR are pushing us to conclude that X-ray coronae are radiatively-compact and have electron temperatures regulated by electron-positron pair production. We show that the predominance of rapidly-rotating objects in current surveys of SMBH spin is entirely unsurprising once one accounts for the observational selection bias resulting from the spin-dependence of the radiative efficiency. We review recent progress in our understanding of fast (v~0.1-0.3c), highly-ionized (mainly visible in FeXXV and FeXXVI lines), high-column density winds that may dominate quasar-mode galactic feedback. Finally, we end with a brief look forward to the promise of Astro-H and future X-ray spectropolarimeters.

description: In this thesis, I zoom in on Harper and his understanding of Russian politics between
1916 and 1921, six years of dramatic transformation in Russia and in Harper’s views on it. In
1916, Russia was a member of the Allies in WWI and trade between it and the United States
nearly tripled from its 1915 levels.13 In February 1917, Petrograd bread riots instigated by angry,
hungry women led to the overthrow of the tsar, whom a Duma Committee quickly replaced with
a Provisional Government. A second revolution that October overthrew the Provisional
Government and brought the Bolsheviks, a radical Marxist party, to power. “The Bolsheviki,” as
Harper referred to them, withdrew Russia from WWI and embraced an unprecedented political
course for the country that called for international socialist revolution, denounced capitalism, and
held workers and working class values supreme. How did Harper react to these events? Given
that his voice carried intellectual clout and engaged a wide audience, how did Harper depict
Russia’s rapid political transformation to Americans? How and in which ways did his views set
the tone for subsequent interactions between Russia and the United States? These questions hold
central importance in this study.

description: HuQin is a family of traditional Chinese bowed string instruments. Playing techniques(PTs) embodied in various playing styles add abundant emotional coloring and aesthetic feelings to HuQin performance. The complex applied techniques make HuQin music a challenging source for fundamental MIR tasks such as pitch analysis, transcription and score-audio alignment. In this paper, we present a multimodal performance dataset of HuQin music that contains audio-visual recordings of 11,992 single PT clips and 57 annotated musical pieces of classical excerpts. We systematically describe the HuQin PT taxonomy based on musicological theory and practical use cases. Then we introduce the dataset creation methodology and highlight the annotation principles featuring PTs. We analyze the statistics in different aspects to demonstrate the variety of PTs played in HuQin subcategories and perform preliminary experiments to show the potential applications of the dataset in various MIR tasks and cross-cultural music studies. Finally, we propose future work to be extended on the dataset.

Regulation of hmp and ldh1 in Staphylococcus aureus
Creators: name: Wilde, Aimee
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Methicillin Resistant Staphylococcus aureus (MRSA) has developed as a prevalent cause of community acquired disease. S. aureus’s effectiveness is due to its exceptional resistance to host immunity, including nitric oxide (NO•). Full NO• resistance requires activation of a gene subset including hmp and ldh1. Hmp converts reactive nitric oxide into non-toxic nitrate. Ldh1 relieves redox imbalance incurred during anaerobic respiration required during NO•-stress. Although preliminary work implicated SrrAB for controlling hmp expression, the regulation is incomplete, implicating additional regulators. Ldh1 is stimulated by glucose, however the exact regulatory mechanism is unknown; my research goal is to identify the precise regulatory mechanisms for both genes. To find these regulators, I conducted a screen of mutants in every non-essential regulatory S. aureus protein by transducing reporter plasmids for each gene into each mutant. Growth curves measuring fluorescence upon NO•-stress to find atypical induction of hmp or ldh1 indicated possible regulators, including SigB and HrcA.

description: The Antlia Cluster is a nearby, dynamically young structure, and its proximity provides a valuable opportunity for detailed study of galaxy and group accretion onto clusters. We present a deep HI mosaic completed as part of spectral line commissioning of the Karoo Array Telescope (KAT-7), and identify infrared counterparts from the WISE extended source catalog to study neutral atomic gas content and star formation within the cluster. We detect 37 cluster members out to a radius of ~0.9 Mpc with M_HI > 5x10^7 M_Sun. Of these, 35 are new HI detections, 27 do not have previous spectroscopic redshift measurements, and one is the Compton thick Seyfert II, NGC 3281, which we detect in HI absorption. The HI galaxies lie beyond the X-ray emitting region 200 kpc from the cluster center and have experienced ram pressure stripping out to at least 600 kpc. At larger radii, they are distributed asymmetrically suggesting accretion from surrounding filaments. Combining HI with optical redshifts, we perform a detailed dynamical analysis of the internal substructure, identify large infalling groups, and present the first compilation of the large scale distribution of HI, and star forming galaxies within the cluster. We find that elliptical galaxy NGC 3268 is at the center of the oldest substructure and argue that NGC 3258 and its companion population are more recent arrivals. Through the presence of HI and on-going star formation, we rank substructures with respect to their relative time since accretion onto Antlia.

description: Mars does not currently have a global dipole magnetic field, and consequently, the atmosphere of the red planet is in direct contact with the incoming solar wind. However, there is a large presence of remnant crustal magnetic fields, of variable strength and direction, in the southern hemisphere and equatorial regions. Their subsequent, complex interactions with the solar wind as they themselves rotate with the planet produces a “hybrid magnetosphere”. The influence of these interactions is seen as complex dynamics that occur in the ionosphere. Thus, in this study, we use nearly 17 years of observations from the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) on board Mars Express to characterise the variability of the topside electron density profiles over the strong anomalies in the Southern hemisphere. The effect of numerous parameters, such as the solar zenith angle (and hence, local time), solar activity, Mars’ season, crustal magnetic field inclination, and solar wind dynamic pressure are investigated. We also compare these observations with the empirical model NeMars to evaluate the degree of variability, as well as with profiles far from these crustal field regions.

description: We present a theoretical investigation of the electronic structure of rutile (metallic) and M$_1$ and M$_2$ monoclinic (insulating) phases of VO$_2$ employing a fully self-consistent combination of density functional theory and embedded dynamical mean field theory calculations. We describe the electronic structure of the metallic and both insulating phases of VO$_2$, and propose a distinct mechanism for the gap opening. We show that Mott physics plays an essential role in all phases of VO$_2$: undimerized vanadium atoms undergo classical Mott transition through local moment formation (in the M$_2$ phase), while strong superexchange within V-dimers adds significant dynamic intersite correlations, which remove the singularity of self-energy for dimerized V-atoms. The resulting transition from rutile to dimerized M$_1$ phase is adiabatically connected to Peierls-like transition, but is better characterized as the Mott transition in the presence of strong intersite exchange. As a consequence of Mott physics, the gap in the dimerized M$_1$ phase is temperature dependent. The sole increase of electronic temperature collapses the gap, reminiscent of recent experiments.

description: With the proliferation of media, particularly digital media, consumers have become more powerful. They now make decisions about when, where and how they consume media (Young, 2014). Such decisions often include the elimination of traditional advertisements. Consumers have found a straight path to entertainment, which thwarts advertisers’ attempts to distract them. The solution? Advertisers have encouraged brands to become the entertainment. With branded integration, advertisers are able to slip into the imaginations of consumers (Chen, 2014). Their stories champion themes and values that are related to their brand identities Athletic apparel brands such as Nike and Adidas have increased their development of branded integration with strong sports themes. In addition, brands that are not connected with sports are beginning to create branded integration centered on major sporting events (Nudd, 2014). This study explored how audiences perceived videos created by advertisers. In addition, it applied two theories, narrative transportation and identification, in order to get a better understanding of how viewers form connections with brands. Seven college undergraduates, who described themselves as sports fans, took part in this study that involved both focus groups and questionnaires. The findings suggest that viewers seek validation and affirmation from advertisers. They prefer brands that use video to affirm their beliefs and practices

description: Social media moderation policies are often at the center of public debate, and their implementation and enactment are sometimes surrounded by a veil of mystery. Unsurprisingly, due to limited platform transparency and data access, relatively little research has been devoted to characterizing moderation dynamics, especially in the context of controversial events and the platform activity associated with them. Here, we study the dynamics of account creation and suspension on Twitter during two global political events: Russia's invasion of Ukraine and the 2022 French Presidential election. Leveraging a large-scale dataset of 270M tweets shared by 16M users in multiple languages over several months, we identify peaks of suspicious account creation and suspension, and we characterize behaviours that more frequently lead to account suspension. We show how large numbers of accounts get suspended within days from their creation. Suspended accounts tend to mostly interact with legitimate users, as opposed to other suspicious accounts, often making unwarranted and excessive use of reply and mention features, and predominantly sharing spam and harmful content. While we are only able to speculate about the specific causes leading to a given account suspension, our findings shed light on patterns of platform abuse and subsequent moderation during major events.

 Distribution:— Guatemala (microendemic).
 Notes:— This species was placed by Fernández Casas (2006d) in sect. Jussieuia, but he did not compare it with any other species of the genus except C. souzae with which he merely stated that it shared similar petiolar glands. He gave no other similarities or differences. Cnidoscolus souzae is a member of sect. Calyptrosolen, and the placement of C. guatimalensis in sect. Jussieuia is questionable. More study is needed to determine the relationship between these two species.

description: We consider a real scalar field in de Sitter background and compute its thermal propagators. We propose that in a dS/CFT context, non-trivial thermal effects as seen by an 'out' observer can be encoded in the anomalous dimensions of the $d = 3$ Ising model. One of these anomalous dimensions, the critical exponent $η$, fixes completely a number of cosmological observables, which we compute

description: The discovery of novae as sources of ~GeV gamma-rays highlights the key role of shocks and relativistic particle acceleration in these transient systems. Although there is evidence for a spectral cut-off above energies ~1-100 GeV at particular epochs in some novae, the maximum particle energy achieved in these accelerators has remained an open question. The high densities of the nova ejecta (~10 orders of magnitude larger than in supernova remnants) render the gas far upstream of the shock neutral and shielded from ionizing radiation. The amplification of the magnetic field needed for diffusive shock acceleration requires ionized gas, thus confining the acceleration process to a narrow photo-ionized layer immediately ahead of the shock. Based on the growth rate in this layer of the hybrid non-resonant cosmic ray current-driven instability (considering also ion-neutral damping), we quantify the maximum particle energy, Emax, across the range of shock velocities and upstream densities of interest. We find values of Emax ~ 10 GeV - 10 TeV, which are broadly consistent with the inferred spectral cut-offs, but which could also in principle lead to emission extending to higher energies >100 GeV accessible to atmosphere Cherenkov telescopes, such as the planned Cherenkov Telescope Array (CTA). Detecting TeV neutrinos with IceCube in hadronic scenarios appears to be more challenging, although the prospects are improved if the shock power during the earliest, densest phases of the nova outburst is higher than is implied by the observed GeV light curves, due to downscattering of the gamma-rays by electrons within the ejecta. Novae provide ideal nearby laboratories to study magnetic field amplification and the onset of cosmic ray acceleration, because other time-dependent sources (e.g. radio supernovae) typically occur too distant to detect as gamma-ray sources.

description: Bus transportation is considered as one of the most convenient and cheapest modes of public transportation in Indian cities. Due to their cost-effectiveness and wide reachability, they help a significant portion of the human population in cities to reach their destinations every day. Although from a transportation point of view they have numerous advantages over other modes of public transportation, they also pose a serious threat of contagious diseases spreading throughout the city. The presence of numerous local spatial constraints makes the process and extent of epidemic spreading extremely difficult to predict. Also, majority of the studies have focused on the contagion processes on scale-free network topologies whereas, spatially-constrained real-world networks such as, bus networks exhibit a wide-spectrum of network topology. Therefore, we aim in this study to understand this complex dynamical process of epidemic outbreak and information diffusion on the bus networks for six different Indian cities using SI and SIR models. This will allow us to identify epidemic thresholds for these networks which will help us in controlling outbreaks by developing node-based immunization techniques.

description: As the first dark matter objects gravitationally condense, a density cusp forms immediately at every initial density maximum. Numerical simulations and theoretical arguments suggest that these prompt cusps can survive until the present day. We show that if dark matter is a thermally produced weakly interacting massive particle, many thousands of prompt cusps with individual masses similar to that of the Earth may be present in every solar mass of dark matter. This radically alters predictions for the amount and spatial distribution of dark matter annihilation radiation. The annihilation rate is boosted by at least an order of magnitude compared to previous predictions, both in the cosmological average and within galaxy-scale halos. Moreover, the signal is predominantly boosted outside of the centers of galactic halos, so alternative targets become significantly more attractive for indirect-detection searches. For example, prompt cusps present new opportunities to test the dark matter interpretation of the Galactic Center gamma-ray excess by searching for similar spectral signatures in the isotropic gamma-ray background and large-scale cosmic structure.

description: Visual-inertial navigation systems are powerful in their ability to accurately estimate localization of mobile systems within complex environments that preclude the use of global navigation satellite systems. However, these navigation systems are reliant on accurate and up-to-date temporospatial calibrations of the sensors being used. As such, online estimators for these parameters are useful in resilient systems. This paper presents an extension to existing Kalman Filter based frameworks for estimating and calibrating the extrinsic parameters of multi-camera IMU systems. In addition to extending the filter framework to include multiple camera sensors, the measurement model was reformulated to make use of measurement data that is typically made available in fiducial detection software. A secondary filter layer was used to estimate time translation parameters without closed-loop feedback of sensor data. Experimental calibration results, including the use of cameras with non-overlapping fields of view, were used to validate the stability and accuracy of the filter formulation when compared to offline methods. Finally the generalized filter code has been open-sourced and is available online.
