description: Family homelessness impacts mental health and wellbeing and is rising in the UK (Carey, 2019; Shelter et al., 2021; Spratt, 2022). Single mothers are most likely to be living in TA with their children, which has been found to be unfit for families (Carey, 2019; McHale, 2021; Spratt, 2022) and impact mental health. However, there is limited research, particularly in rural areas in the UK. This study aimed to explore experiences of single mothers who are living in TA in rural Suffolk, and to explore their perception of the impacts on their and their child’s mental health, wellbeing, and relationships. Eight semi-structured qualitative interviews were conducted with single mothers who had recent experience of living in Temporary Accommodation in Suffolk. Data was analysed via reflexive thematic analysis (Braun & Clarke, 2006; 2019). Five main themes were generated: ‘Living in Temporary Accommodation harm women’s and children’s wellbeing and mental health ‘, ‘Living in Temporary Accommodation: A barrier to parenting’, “A big black hole of nothingness”: Powerless and trapped in cycles of harm’, ‘‘It’s like my life is on hold’’: The double-edged nature of ‘temporary’ accommodation and ‘Location, Location, Location: Where you are housed matters.’ Findings suggest that single mothers’ experiences of living in TA impacted their mental health and their relationships. Living with uncertainty, being treated poorly by others and the responsibilities of being a single mother in rural TA impacted their experiences. Recommendations and ideas for further research are discussed.

Neuropsychological Consequences of COVID-19: Long COVID and the Relationship with Acute Illness

description: Rationale and aims: Long COVID has a substantial impact on quality of life for many, with international prevalence related to the worldwide COVID-19 pandemic. However, acute illness severity may not always predict the neuropsychological consequences in long COVID. This may be due to unique neurotropic mechanisms of the virus. Research to date has explored up to 12 months post infection but assessment is largely limited to screening and relies on cognitive testing alone to draw conclusions. Therefore, this research project aimed to answer two research questions: ‘what are the objectively measured cognitive and emotional consequences of COVID-19/ long COVID at 20-24 months?’ and ‘how does this relate to the subjective experience of illness from COVID-19 and illness severity?’ Methodology: A two-part sequential explanatory mixed-methods design was used, firstly with inferential statistics to analyse data from cognitive testing and self-report mood measures. Participants (n=19) were assessed 20-24 months post infection. Results were compared between two groups: those that accessed a virtual hospital service (n=9) during the acute stages and those that accessed a long COVID service (n=10) at some stage after. Thematic analysis captured information from questionnaire responses to enhance findings. Discussion: Many appear to recover cognitive function toward the 2-year mark, but some specific deficit in visuospatial, psychomotor and executive function was observed, which appears to be irrespective of illness severity. These concerns, often in combination with pandemic related concerns, had a substantial impact on quality of life for participants. Implications: Due to the varied cognitive profile and substantial impact of long COVID, future research should utilise comprehensive cognitive testing in combination with accounts of participants’ experiences of symptoms. Long COVID services could consider neuropsychological expertise for individualised assessment and therapy intervention.

description: We present new constraints on the high-temperature emission measure of a non-flaring solar active region using observations from the recently flown Focusing Optics X-ray Solar Imager sounding rocket payload. FOXSI has performed the first focused hard X-ray (HXR) observation of the Sun in its first successful flight on 2012 November 2. Focusing optics, combined with small strip detectors, enable high-sensitivity observations with respect to previous indirect imagers. This capability, along with the sensitivity of the HXR regime to high-temperature emission, offers the potential to better characterize high-temperature plasma in the corona as predicted by nanoflare heating models. We present a joint analysis of the differential emission measure (DEM) of active region 11602 using coordinated observations by FOXSI, Hinode/XRT and Hinode/EIS. The Hinode-derived DEM predicts significant emission measure between 1 MK and 3 MK, with a peak in the DEM predicted at 2.0-2.5 MK. The combined XRT and EIS DEM also shows emission from a smaller population of plasma above 8 MK. This is contradicted by FOXSI observations that significantly constrain emission above 8 MK. This suggests that the Hinode DEM analysis has larger uncertainties at higher temperatures and that >8 MK plasma above an emission measure of 3x10^44 cm^-3 is excluded in this active region.

description: Interferometry is a powerful technique used to extract valuable information about the wave function of a system. In this work, we study the response of spin carriers to the effective field textures developed in curved one-dimensional interferometric circuits subject to the joint action of Rashba and Dresselhaus spin-orbit interactions. By using a quantum network technique, we establish that the interplay between these two non-Abelian fields and the circuit's geometry modify the geometrical characteristics of the spinors, particularly on square circuits, leading to the localisation of the electronic wave function and the suppression of the quantum conductance. We propose a topological interpretation by classifying the corresponding spin textures in terms of winding numbers.

Half-baked men: doughface masculinity and the antebellum politics of household
Creators: name: Lynn, Joshua A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: In the antebellum politics of household, political legitimacy stemmed from domestic life. As white northern families and southern plantation households constituted distinct domesticities, northern Doughface Democrats betrayed the northern home by catering to southern planters. Doughfaces argued that they demonstrated a manly independence in treating all families equally. In reality, however, their doctrine of popular sovereignty unfairly benefited southern households in the federal territories in the late 1840s and 1850s. Antislavery northerners responded with accusations of unmasculine servility. In the 1856 presidential election, Democrats portrayed James Buchanan, a Doughface and a bachelor, as a man who transcended competing conceptions of the household. At the same time, they offered him to southern voters as a fellow paternalist. Northerners subsequently charged Buchanan with treason against the northern home and against the concept of household itself. Doughfacism illustrates the intersection of politics, gender, and domesticity, and how political culture began at home.

description: We present computational results and tables of the equation-of-state, thermodynamic properties, and shock Hugoniot for hot dense fluid deuterium. The present results are generated using a recently developed chemical model that takes into account different high density effects such as Coulomb interactions among charged particles, partial degeneracy, and intensive short range hard core repulsion. Internal partition functions are evaluated in a statistical-mechanically consistent way implementing recent developments in the literature. The shock Hugoniot curve derived from the present tables is in reasonable overall agreement with the Hugoniot derived from the Nova-laser shock wave experiments on liquid deuterium, showing that deuterium has a significantly higher compressibility than predicted by the SESAME tables or by Path Integral Monte Carlo (PIMC) calculations. Computational results are presented as surface plots for the dissociated fraction, degree of ionization, pressure, and specific internal energy for densities ranging from 0.0001 to 40 g/cm3 and temperatures from 2000 to ~ 106 K. Tables for values of the above mentioned quantities in addition to the specific heat at constant pressure, cp, ratio of specific heats, cp/cv, sound speed and Hugoniot curve (for a specific initial state) are presented for practical use.

description: Hydra tissue fragments excised freshly from Hydra body bend spontaneously to some quasi-stable shape in several minutes. We propose that the spontaneous bending is driven mechanically by supracellular actomyosin bundles inherited from parent Hydra. An active-laminated-plate model is constructed, from which we predict that the fragment shape characterized by spontaneous curvature is determined by its anisotropy in contractility and elasticity. The inward bending to endoderm side is ensured by the presence of a soft intermediate matrix (mesoglea) layer. The bending process starts diffusively from the edges and relaxes exponentially to the final quasi-stable shape. Two characteristic time scales are identified from the dissipation due to viscous drag and interlayer frictional sliding, respectively. The former is about 0.01 seconds, but the latter is much larger, about several minutes, consistent with experiments.

The Ahhiyawa Question: Providing Archaeological Evidence for the interconnection between the Hittites and the Mycenaeans
Creators: name: Wagner, Ana

Year: 2016

description: The question of whether or not the Hittite term ‘Ahhiyawa’ refers to the Mycenaeans in Greece — particularly the Achaeans — has long been debated. There is clear evidence for the interaction between these two cultures, as seen in the material evidence, and linguistically, the term ‘Ahhiyawa’ is not dissimilar to the Greek ‘Achaea;’ the material and linguistic study of the connections between the Hittites and the Mycenaeans has therefore led scholars from several backgrounds to argue that the Ahhiyawa “kingdom” was that of the Mycenaeans.This paper analyzes both the linguistic and material evidence for the interconnections between these two cultures, but is more heavily focused on the material evidence, in the hopes of determining whether or not the Ahhiyawa Kingdom was that of the Mycenaeans, and attempt to place Ahhiyawa geographically.

description: One of the major challenges with cell-free (CF) massive multiple-input multiple-output (MIMO) networks is providing backhaul links for a large number of distributed access points (APs). In general, providing fiber optics backhaul for these APs is not cost-effective and also reduces network scalability. Wireless backhauling can be a promising solution that can be integrated with wireless access links to increase spectrum efficiency. In this paper, the application of integrated access and backhaul (IAB) technique in millimeter-wave (mmWave) CF massive MIMO systems is investigated. The access and backhaul links share a frequency spectrum in the mmWave bands, and in both, hybrid beamforming techniques are adopted for signal transmission. The bandwidth allocation (division) parameter between the two link types as well as the beamforming matrices are optimized to maximize the end-to-end data-rate. This leads to a non-convex optimization problem for which an efficient solution method is proposed. The simulation results show the effectiveness of the IAB technique and our proposed scheme in CF massive MIMO systems. These simulations also compare the proposed hybrid beamforming method with a fully digital solution in terms of the number of radio frequency (RF) chains and the volume of backhaul traffic. Finally, the effect of increasing the number of APs on the users data rates in terms of wireless access and backhaul links constraints is also examined.

On the Star Formation Law for Spiral and Irregular Galaxies
Creators: name: Elmegreen, Bruce G.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: A dynamical model for star formation on a galactic scale is proposed in which the interstellar medium is constantly condensing to star-forming clouds on the dynamical time of the average midplane density, and the clouds are constantly being disrupted on the dynamical time scale appropriate for their higher density. In this model, the areal star formation rate scales with the 1.5 power of the total gas column density throughout the main regions of spiral galaxies, and with a steeper power, 2, in the far outer regions and in dwarf irregular galaxies because of the flaring disks. At the same time, there is a molecular star formation law that is linear in the main and outer parts of disks and in dIrrs because the duration of individual structures in the molecular phase is also the dynamical time scale, canceling the additional 0.5 power of surface density. The total gas consumption time scales directly with the midplane dynamical time, quenching star formation in the inner regions if there is no accretion, and sustaining star formation for ~100 Gyr or more in the outer regions with no qualitative change in gas stability or molecular cloud properties. The ULIRG track follows from high densities in galaxy collisions.

description: This article explores the connection between radical isogenies and modular curves. Radical isogenies are formulas designed for the computation of chains of isogenies of fixed small degree $N$, introduced by Castryck, Decru, and Vercauteren at Asiacrypt 2020. One significant advantage of radical isogeny formulas over other formulas with a similar purpose is that they eliminate the need to generate a point of order $N$ that generates the kernel of the isogeny. While radical isogeny formulas were originally developed using elliptic curves in Tate normal form, Onuki and Moriya have proposed radical isogeny formulas of degrees $3$ and $4$ on Montgomery curves and attempted to obtain a simpler form of radical isogenies using enhanced elliptic and modular curves. In this article, we translate the original setup of radical isogenies in Tate normal form into the language of modular curves. Additionally, we solve an open problem introduced by Onuki and Moriya regarding radical isogeny formulas on $X_0(N).$

Decentralized Throughput Maximizing Policies for Deadline-Constrained Wireless Networks

description: We consider multi-hop wireless networks serving multiple flows in which only packets that meet hard end-to-end deadline constraints are useful, i.e., if a packet is not delivered to its destination node by its deadline, it is dropped from the network. We design decentralized scheduling policies for such multi-hop networks that attain the maximum throughput of useful packets. The resulting policy is decentralized in the sense that in order to make a transmission decision, a node only needs to know the "time-till-deadline" of the packets that are currently present at that node, and not the state of the entire network. The key to obtaining an easy-to-implement and highly decentralized policy is to replace the hard constraint on the number of simultaneous packet transmissions that can take place on the outgoing links of a node, by a time-average constraint on the number of transmissions. The policy thus obtained is guaranteed to provide maximum throughput. Analysis can be extended to the case of time-varying channel conditions in a straightforward manner. Simulations showing significant improvement over existing policies for deadline based scheduling, such as Earliest Deadline First, and supporting the theory, are presented.

description: Motivated by the higher Chern bands of twisted graphene multilayers, we consider flat bands with arbitrary Chern number $C$ with ideal quantum geometry. While $C>1$ bands differ from Landau levels, we show that these bands host exact fractional Chern insulator (FCI) ground states for short range interactions. We show how to decompose ideal higher Chern bands into separate ideal bands with Chern number $1$ that are intertwined through translation and rotation symmetry. The decomposed bands admit an $SU(C)$ action that combines real space and momentum space translations. Remarkably, they also allow for analytic construction of exact many-body ground states, such as generalized quantum Hall ferromagnets and FCIs, including flavor-singlet Halperin states and Laughlin ferromagnets in the limit of short-range interactions. In this limit, the $SU(C)$ action is promoted to a symmetry on the ground state subspace. While flavor singlet states are translation symmetric, the flavor ferromagnets correspond to translation broken states and admit charged skyrmion excitations corresponding to a spatially varying density wave pattern. We confirm our analytic predictions with numerical simulations of ideal bands of twisted chiral multilayers of graphene, and discuss consequences for experimentally accessible systems such as monolayer graphene twisted relative to a Bernal bilayer.

description: In this paper, we introduce a new deep convolutional neural network (ConvNet) module that promotes competition among a set of multi-scale convolutional filters. This new module is inspired by the inception module, where we replace the original collaborative pooling stage (consisting of a concatenation of the multi-scale filter outputs) by a competitive pooling represented by a maxout activation unit. This extension has the following two objectives: 1) the selection of the maximum response among the multi-scale filters prevents filter co-adaptation and allows the formation of multiple sub-networks within the same model, which has been shown to facilitate the training of complex learning problems; and 2) the maxout unit reduces the dimensionality of the outputs from the multi-scale filters. We show that the use of our proposed module in typical deep ConvNets produces classification results that are either better than or comparable to the state of the art on the following benchmark datasets: MNIST, CIFAR-10, CIFAR-100 and SVHN.

Evaluation of Six Chromogenic Diagnostic Culture Media for a One Health ESBL E. coli Indicator System for Global AMR Surveillance
Creators: name: Koltun, Andy

description: To facilitate multisectoral antimicrobial resistance (AMR) surveillance, the World Health Organization (WHO) has proposed an integrated culture-based surveillance methodology for direct quantification of extended-spectrum-β-lactam resistant (ESBL) Escherichia coli (E-Ec) in environmental hotspots and for detection in other ‘One Health’ hotspots. We evaluated six candidate ESBL-selective agar media for E-Ec detection and quantification, quantification of E-Ec as a proportion of total E. coli, and presumptive identification and characterization of E-Ec in raw sewage, poultry waste, and urban surface water analyses. E-Ec quantification used standard membrane filtration (surface water) and spread plating (other samples) methods. MALDI-TOF and VITEK analyses verified isolates’ identity and AMR profiles. Results showed Tryptone Bile Glucoronic (TBX) medium was most sensitive for E-Ec quantification overall (though not significantly so) and significantly more accurate in presumptively identifying and characterizing isolates. These findings support adoption of this AMR indicator system using TBX to provide integrated, accurate AMR surveillance methods globally.

Using hydrostatic pressure method, we demonstrate that hydrostatic pressure up to 1.2 GPa can significantly enhance flux pinning or Jc by a factor of up to 5 especially in both low and high fields in optimally doped Ba0.6K0.4Fe2As2 crystals. Our analysis on the flux pining mechanism indicate that both pinning centre number density (Np) and pinning force (Fp) are greatly increased by the pressure and contribute to strong pinning.

description: Antiferromagnetic materials are magnetic inside, however, the direction of their ordered microscopic moments alternates between individual atomic sites. The resulting zero net magnetic moment makes magnetism in antiferromagnets invisible on the outside. It also implies that if information was stored in antiferromagnetic moments it would be insensitive to disturbing external magnetic fields, and the antiferromagnetic element would not affect magnetically its neighbors no matter how densely the elements were arranged in a device. The intrinsic high frequencies of antiferromagnetic dynamics represent another property that makes antiferromagnets distinct from ferromagnets. The outstanding question is how to efficiently manipulate and detect the magnetic state of an antiferromagnet. In this article we give an overview of recent works addressing this question. We also review studies looking at merits of antiferromagnetic spintronics from a more general perspective of spin-ransport, magnetization dynamics, and materials research, and give a brief outlook of future research and applications of antiferromagnetic spintronics.

description: We present a smoothly broken power law functional form (that we refer to as a Broken Neural Scaling Law (BNSL)) that accurately models & extrapolates the scaling behaviors of deep neural networks (i.e. how the evaluation metric of interest varies as amount of compute used for training (or inference), number of model parameters, training dataset size, model input size, number of training steps, or upstream performance varies) for various architectures & for each of various tasks within a large & diverse set of upstream & downstream tasks, in zero-shot, prompted, & finetuned settings. This set includes large-scale vision, language, audio, video, diffusion, generative modeling, multimodal learning, contrastive learning, AI alignment, AI capabilities, robotics, out-of-distribution (OOD) generalization, continual learning, transfer learning, uncertainty estimation / calibration, OOD detection, adversarial robustness, distillation, sparsity, retrieval, quantization, pruning, fairness, molecules, computer programming/coding, math word problems, "emergent phase transitions", arithmetic, supervised learning, unsupervised/self-supervised learning, & reinforcement learning (single agent & multi-agent). When compared to other functional forms for neural scaling, this functional form yields extrapolations of scaling behavior that are considerably more accurate on this set. Moreover, this functional form accurately models & extrapolates scaling behavior that other functional forms are incapable of expressing such as the nonmonotonic transitions present in the scaling behavior of phenomena such as double descent & the delayed, sharp inflection points present in the scaling behavior of tasks such as arithmetic. Lastly, we use this functional form to glean insights about the limit of the predictability of scaling behavior. Code is available at https://github.com/ethancaballero/broken_neural_scaling_laws

title: Promoting Condom Use Among Young People Employing Health and Social Psychology

description: The best way to prevent the sexual transmission of the HIV virus, which causes AIDS and death, is by using condoms. However, these are still so unpopular and said to reduce sexual sensation and break the sexual mood to the extent that research has even suggested that a rectal microbicide should be found as a potential alternative for preventing the spread of HIV among gay men. A microbicide may indeed be an alternative against the fatality of HIV, but there must be also ways of making condoms become trending and part of sexual pleasure. Thus, this thesis looks at ways of persuading people to use condoms. Of paramount importance, it was found in this thesis that aiming at altering the variables based on the TPB in order to change people’s condom use is likely to be only partially successful. That is, the present evidence shows that changes from time 1 to time 2, on attitudes, perceived behavioural control and behavioural expectations, but not subjective norms (see Chapter 8), affected condom use with a high risk partner at time 3. A key conclusion is that messages encouraging condom use would gain by targeting people according to their sensation seeking personalities. Sensation seeking influences sexual behaviour such as that HSS (high sensation seekers) are more prone to risky sexual practices (see Chapter 5). Besides, it overwhelms the influence of prior sexual behaviour, and the effects of gender on to expectations and intentions can be accounted for by differences in sensations seeking, too (Chapter 6). A further reason to include sensation seeking in the forecast of sexual behaviour is that it acts as a moderator in the prediction of intentions and condom use (see Chapter 6), as follows. For LSS (low sensation seekers) anticipated regret is more strongly associated with intentions to use condoms, whilst for HSS behavioural principles are more strongly associated with intentions to use condoms. Intentions to use condoms in risky sexual encounters are more strongly predictive of condom use with affairs among LSS than HSS individuals. Moreover, sensation seeking moderates the impact of persuasive messages encouraging condom use (Chapter 8), such as HSS appear to be mainly persuaded to use condoms by the peripheral route and LSS by the central route of message processing. In summary, the mere change from time 1 to time 2 and the associations among some variables based on the TPB may be largely irrelevant to overall condom use. Yet, the role sensation seeking plays in sexuality and message processing is crucial in condom use. Therefore, it is advisable to consider personality differences in sensation seeking in the promotion of condom use.
Evaluation of the paper point technique for locating the root canal apical exit

description: A new method for determining root canal working length (WL), the paper point technique (PPT), has been claimed to be accurate and reproducible, but has not been formally evaluated. Hypothesis: WL determination is more accurate when the Electronic Apex Locator Technique (EALT) is supplemented with PPT compared to EALT alone. The lengths of 84 root canals of unsalvageable human teeth were measured first using EALT, then PPT. Endodontic files were cemented to the position indicated by PPT. The teeth were extracted and microCT-scanned. In 71 canals that provided adequate readings for both EALT and PPT, the RCAE to file tip distance was measured to 20 μm resolution. Both techniques showed (1) moderate agreement and (2) excellent repeatabilities. There was (3) a significantly greater accuracy in locating the RCAE when PPT was used compared to EALT alone (p ≤ 0.0051). Conclusion: It may be advisable to supplement the EALT measurement with PPT.

description: Rotation period clustering in prograde/retrograde rotators might indicate the preliminary indication of the Slivan state in the Koronis family as a result of the YORP effect. We follow the general scenario of dispersion in semimajor axis of the asteroid family members to separate prograde and retrograde rotators in the Koronis family. From the available rotation periods obtained from PTF/iPTF, we can not found the rotation period clustering of objects with H grater than 12 mag in the Koronis family. This could be the result of the intermittent collisional process of small asteroids (D less than ~20 km) which leads to astray Yarkovsky drifting. Measurement of the pole orientations of our sample will verify our preliminary result and validate our method.

description: Bohnenblust--Hille inequalities for Boolean cubes have been proven with dimension-free constants that grow subexponentially in the degree \cite{defant2019fourier}. Such inequalities have found great applications in learning low-degree Boolean functions \cite{eskenazis2022learning}. Motivated by learning quantum observables, a qubit analogue of Bohnenblust--Hille inequality for Boolean cubes was recently conjectured in \cite{RWZ22}. The conjecture was resolved in \cite{CHP}. In this paper, we give a new proof of these Bohnenblust--Hille inequalities for qubit system with constants that are dimension-free and of exponential growth in the degree. As a consequence, we obtain a junta theorem for low-degree polynomials. Using similar ideas, we also study learning problems of low degree quantum observables and Bohr's radius phenomenon on quantum Boolean cubes.
