description: BackgroundPreventing HIV infection among young people is a priority for the Liberian government. Data on the young people in Liberia are scarce but needed to guide HIV programming efforts.MethodsWe used the Priorities for Local AIDS Control Efforts (PLACE) method to gather information on risk behaviors that young people (ages 14 to 24) engage in or are exposed to that increase their vulnerability for HIV infection. Community informants identified 240 unique venues of which 150 were visited and verified by research staff. 89 of the 150 venues comprised our sampling frame and 571 females and 548 males were interviewed in 50 venues using a behavioral survey.ResultsNinety-one percent of females and 86% of males reported being sexually active. 56% of females and 47% of males reported they initiated sexual activity before the age of 15. Among the sexually active females, 71% reported they had received money or a gift for sex and 56% of males reported they had given money or goods for sex. 20% of females and 6% males reported that their first sexual encounter was forced and 15% of females and 6% of males reported they had been forced to have sex in the past year. Multiple partnerships were common among both sexes with 81% females and 76% males reporting one or more sex partners in the past four weeks. Less than 1% reported having experiences with injecting drugs and only 1% of males reporting have sex with men. While knowledge of HIV/AIDS was high, prevention behaviors including HIV testing and condom use were low.ConclusionYouth-focused HIV efforts in Liberia need to address transactional sex and multiple and concurrent partnerships. HIV prevention interventions should include efforts to meet the economic needs of youth.

Overview

Anthony Powell’s universally acclaimed epic A Dance to the Music of Time offers a matchless panorama of twentieth-century London. Now, for the first time in decades, readers in the United States can read the books of Dance as they were originally published—as twelve individual novels—but with a twenty-first-century twist: they’re available only as e-books. Casanova’s Chinese Restaurant (1960), the fifth book, finds Nick marrying Isobel Tolland and launching happily into family life—including his new role as brother-in-law to Isobel’s many idiosyncratic siblings. But even as Nick’s life is settling down, those of his friends are full of drama and heartache: his best friend, Hugh Moreland, is risking his marriage on a hopeless affair, while Charles Stringham has nearly destroyed himself with drink. Full of Powell’s typically sharp observations about life and love, Casanova’s Chinese Restaurant offers all the rewards and frustrations, pleasures and regrets of one’s thirties. "Anthony Powell is the best living English novelist by far. His admirers are addicts, let us face it, held in thrall by a magician."—Chicago Tribune "A book which creates a world and explores it in depth, which ponders changing relationships and values, which creates brilliantly living and diverse characters and then watches them grow and change in their milieu. . . . Powell's world is as large and as complex as Proust's."—Elizabeth Janeway, New York Times "One of the most important works of fiction since the Second World War. . . . The novel looked, as it began, something like a comedy of manners; then, for a while, like a tragedy of manners; now like a vastly entertaining, deeply melancholy, yet somehow courageous statement about human experience."—Naomi Bliven, New Yorker  “The most brilliant and penetrating novelist we have.”—Kingsley Amis

description: We briefly review earlier and report original experimental results in the context of metastable or possible superconducting materials. We show that applied electric field induces conducting state in Copper Chloride (CuCl) whose characteristics resemble behavior of sliding charge-density-wave(s) (CDW). We discuss whether the sliding CDW or collective transport of similar ordered charge phase(s) may account for the problem of "high-temperature superconductivity" observed in this and other materials, including Cadmium Sulfide (CdS), metal-ammonia solutions, polymers, amorphous carbon and tungsten oxides. We also discuss a local superconductivity that occurs at the surface of graphite and amorphous carbon under deposition of foreign atoms/molecules.

description: Combinatorial optimization is of general interest for both theoretical study and real-world applications. Fast-developing quantum algorithms provide a different perspective on solving combinatorial optimization problems. In this paper, we propose a quantum-inspired tensor-network-based algorithm for general locally constrained combinatorial optimization problems. Our algorithm constructs a Hamiltonian for the problem of interest, effectively mapping it to a quantum problem, then encodes the constraints directly into a tensor network state and solves the optimal solution by evolving the system to the ground state of the Hamiltonian. We demonstrate our algorithm with the open-pit mining problem, which results in a quadratic asymptotic time complexity. Our numerical results show the effectiveness of this construction and potential applications in further studies for general combinatorial optimization problems.

description: BackgroundThere is a high unmet need for sexual and reproductive health (SRH) information and services among youth (ages 15-24) worldwide (MacQuarrie KLD. Unmet Need for Family Planning among Young Women: Levels and Trends 2014). With the proliferation of mobile technology, and its popularity with this age group, mobile phones offer a novel and accessible platform for a discreet, on-demand service providing SRH information. The Adolescent/Youth Reproductive Mobile Access and Delivery Initiative for Love and Life Outcomes (ARMADILLO) formative study will inform the development of an intervention, which will use the popular channel of SMS (text messages) to deliver SRH information on-demand to youth.Methods/DesignFollowing the development of potential SMS message content in partnership with SRH technical experts and youth, formative research activities will take place over two phases. Phase 1 will use focus group discussions (FGDs) with youth and parents/caregivers to develop and test the appropriateness and acceptability of the SMS messages. Phase 2 will consist of ‘peer piloting’, where youth participants will complete an SRH outcome-focused pretest, be introduced to the system and then have three weeks to interact with the system and share it with friends. Participants will then return to complete the SRH post-test and participate in an in-depth interview about their own and their peers’ opinions and experiences using ARMADILLO.DiscussionThe ARMADILLO formative stage will culminate in the finalization of country-specific ARMADILLO messaging. Reach and impact of ARMADILLO will be measured at later stages. We anticipate that the complete ARMADILLO platform will be scalable, with the potential for national-level adoption.

description: Matching MRI brain images between patients or mapping patients' MRI slices to the simulated atlas of a brain is key to the automatic registration of MRI of a brain. The ability to match MRI images would also enable such applications as indexing and searching MRI images among multiple patients or selecting images from the region of interest. In this work, we have introduced robustness, accuracy and cumulative distance metrics and methodology that allows us to compare different techniques and approaches in matching brain MRI of different patients or matching MRI brain slice to a position in the brain atlas. To that end, we have used feature detection methods AGAST, AKAZE, BRISK, GFTT, HardNet, and ORB, which are established methods in image processing, and compared them on their resistance to image degradation and their ability to match the same brain MRI slice of different patients. We have demonstrated that some of these techniques can correctly match most of the brain MRI slices of different patients. When matching is performed with the atlas of the human brain, their performance is significantly lower. The best performing feature detection method was a combination of SIFT detector and HardNet descriptor that achieved 93% accuracy in matching images with other patients and only 52% accurately matched images when compared to atlas.

Modular Dynamical Semigroups for Quantum Dissipative Systems

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce a class of Markovian quantum master equations, able to describe the dissipative dynamics of a quantum system weakly coupled to one or several heat baths. The dissipative structure is driven by an entropic operator, the so called modular Hamiltonian, which makes it nonlinear. The generated Modular Dynamical Semigroup (MDS) is not, in general, a Quantum Dynamical Semigroup (QDS), whose dynamics is of the popular Lindblad type. The MDS has a robust thermodynamic structure, which guarantees for the positivity of the time evolved state, the correct steady state properties, the positivity of the entropy production, a positive Onsager matrix and Onsager symmetry relations (arising from Green-Kubo formulas). We show that the celebrated Davies generator, obtained through the Born and the secular approximations, generates a MDS. By unravelling the modular structure of the former, we provide a different and genuinely nonlinear MDS, not of QDS type, which is free from the severe spectral restrictions of the Davies generator, while still being supported by a weak coupling limit argument. With respect to the latter, the present work is a substantial extension of \cite{Ottinger2011_GEO,Ottinger2010_TLS_DHO}
Biophilic design of building façades from an Evolutionary Psychology framework

Publisher: name: Visions for Sustainability
Year: 2022

description: Built environments that integrate representations of the natural world into façades and interiors benefit occupant psycho-physiological well-being and behavior. However, the biophilic quality of buildings does not de-pend exclusively on “green”, but also upon “organized complexity” in their structure. In this exploratory study we compare quantitative (Visual Atten-tion Software) and qualitative approaches (self-rating scales) in the perception of biophilic design of building façades. Eight façades varying in their degree of biophilic design (High, Medium, Low, No biophilic qualities) were assessed on the Perceived Restorativeness Scale-11, on preference, and on a series of physical aesthetic attributes. The eight façades were scanned with Visual At-tention Software (VAS). These measures show many overlapping points. VAS can be considered a way to operationalize the engagement of attention in the first 3-5 seconds of gaze in exploring building design, and self-ratings assess-ments a measure of to what extent the building is perceived as restorative. Higher perceived restorativeness and preference match a higher degree of bi-ophilic design, which corresponds to a building where vegetation is integrated in an organic structure. Vegetation is not the only biophilic characteristic to be considered in biophilic design and this emerges clearly from self-ratings and VAS. Exploring organized complexity is fundamental for understanding human responses to architecture.

Overview

One boy's search for his father leads him to Puerto Rico in this moving middle-grade novel, for fans of Ghost and See You in the Cosmos. Marcus Vega is six feet tall, 180 pounds, and the owner of a premature mustache. When you look like this and you're only in the eighth grade, you're both a threat and a target. After a fight at school leaves Marcus facing suspension, Marcus's mom decides it's time for a change of environment. She takes Marcus and his younger brother to Puerto Rico to spend a week with relatives they don't remember or have never met. But Marcus can't focus knowing that his father—who walked out of their lives ten years ago—is somewhere on the island. So begins Marcus's incredible journey, a series of misadventures that take him all over Puerto Rico in search of his elusive namesake. Marcus doesn't know if he'll ever find his father, but what he ultimately discovers changes his life. And he even learns a bit of Spanish along the way.

Effects of Tibolone Metabolites on Human Endometrial Cell Lines in Co-culture

description: In human endometrium, cell proliferation is regulated by ovarian steroids through heterotypic interactions between stromal and epithelial cells populating this tissue. We tested the proliferative effects of tibolone and its metabolites using endometrial co-cultures that mimic the normal proliferative response to hormones. We found that both the Δ4-tibolone metabolite and the pure progestin ORG2058 counteract estradiol-driven epithelial cell proliferation. Surprisingly, the estrogen receptor binding 3-hydroxyl-metabolites of tibolone also counteracted estradiol-driven proliferation. Inhibition of proliferation by 3β-OH-tibolone was abrogated by low doses of the progesterone receptor antagonist mifepristone, This suggests that 3β-OH-tibolone is converted to a progestagenic metabolite. We found that the stromal cells used in the co-cultures express high levels of the ketosteroid dehydrogenase, AKR1C2, which is able to oxidize 3β-OH-tibolone back to tibolone. Thus the unexpected progestagenic effect of 3β-OH-tibolone in these co-cultures may be due to metabolic activity present in the stromal cells of the co-cultures.
Non-Abelian String of a Finite Length

description: We consider world-sheet theories for non-Abelian strings assuming compactification on a cylinder with a finite circumference $L$ and periodic boundary conditions. The dynamics of the orientational modes is described by two-dimensional CP$(N-1)$ model. We analyze both non-supersymmetric (bosonic) model and ${\mathcal N}=(2,2)$ supersymmetric CP$(N-1)$ emerging in the case of 1/2-BPS saturated strings in \ntwo supersymmetric QCD with $N_f=N$. The non-supersymmetric case was studied previously; technically our results agree with those obtained previously, although our interpretation is totally different. In the large-$N$ limit we detect a phase transition at $L\sim Λ_{\rm CP}^{-1}$ (which is expected to become a rapid crossover at finite $N$). If at large $L$ the CP$(N-1)$ model develops a mass gap and is in the Coulomb/confinement phase, with exponentially suppressed finite-$L$ effects, at small $L$ it is in the deconfinement phase, and the orientational modes contribute to the Lüsher term. The latter becomes dependent on the rank of the bulk gauge group. In the supersymmetric CP$(N-1)$ models at finite $L$ we find a large-$N$ solution which was not known previously. We observe a single phase independently of the value of $LΛ_{\rm CP}$. For any value of this parameter a mass gap develops and supersymmetry remains unbroken. So does the $SU(N)$ symmetry of the target space. The mass gap turns out to be independent of the string length. The Lüscher term is absent due to supersymmetry.

description: Let $C$ be a cubic form with rational coefficients in $n$ variables, and let $h$ be the $h$-invariant of $C$. Let $L_1, \ldots, L_r$ be linear forms with real coefficients such that if $\boldsymbolα \in \mathbb{R}^r \setminus \{ \boldsymbol{0} \}$ then $\boldsymbolα \cdot \mathbf{L}$ is not a rational form. Assume that $h > 16 + 8 r$. Let $\boldsymbolτ \in \mathbb{R}^r$, and let $η$ be a positive real number. We prove an asymptotic formula for the weighted number of integer solutions $\mathbf{x} \in [-P,P]^n$ to the system $C(\mathbf{x}) = 0, \: |\mathbf{L}(\mathbf{x}) - \boldsymbolτ| < η$. If the coefficients of the linear forms are algebraically independent over the rationals, then we may replace the $h$-invariant condition with the hypothesis $n > 16 + 9 r$, and show that the system has an integer solution. Finally, we show that the values of $\mathbf{L}$ at integer zeros of $C$ are equidistributed modulo one in $\mathbb{R}^r$, requiring only that $h > 16$.

description: Biocomputing technologies exploit biological communication mechanisms involving cell-cell signal propagation to perform computations. Researchers recently worked toward realising logic gates made by neurons to develop novel devices such as organic neuroprostheses or brain implants made by cells, herein termed living implants. Several challenges arise from this approach, mainly associated with the stochastic nature and noise of neuronal communication. Since astrocytes play a crucial role in the regulation of neurons activity, there is a possibility whereby astrocytes can be engineered to control synapses favouring reliable biocomputing. This work proposes a mathematical model of neuronal logic gates involving neurons and astrocytes, realising OR and AND gating. We use a shallow coupling of both the Izhikevich and Postnov models to characterise gating responses with spike pattern variability and astrocyte synaptic regulation. Logic operation error ratio and accuracy assess the AND and OR gates' performances at different synaptic Gaussian noise levels. Our results demonstrate that the astrocyte regulating activity can effectively be used as a denoising mechanism, paving the way for highly reliable biocomputing implementations.

Year: 2015

description: We document differences in human-capital deployment between diversified and focused firms. We find that diversified firms have higher labor productivity and that they redeploy labor to industries with better prospects in response to changing opportunities. The opportunities and incentives provided in internal labor markets in turn affect the development of workers' human capital. We find that workers more frequently transition to other industries in which their diversified firms operate and with smaller wage losses compared with workers in the open market, even when they leave their original firms. Overall, internal labor markets provide a bright side to corporate diversification.

description: Human activities during the Anthropocene result in habitat degradation that has been associated with biodiversity loss and taxonomic homogenization of ecological communities. Here we estimated effects of eutrophication and heavy metal contamination, separately and in combination, in explaining zooplankton species composition during the past 125–145 years using analysis of daphniid diapausing egg banks from four lakes in the northeastern USA. We then examined how these community shifts influenced patterns of diversity and homogenization. Analysis of past lake production (via subfossil pigments) and metal contamination (via sedimentary metals) demonstrated that eutrophication alone (19–39%) and in combination with metal pollution (17–54%) explained 36–79% of historical variation in daphniid species relative abundances in heavily fertilized lakes. In contrast, metal pollution alone explained the majority (72%) of historical variation in daphniid assemblages at the oligotrophic site. Several species colonization events in eutrophying lakes resulted in increased species richness and gamma diversity through time. At the same time, daphniid assemblages in three eutrophied lakes became more similar to each other (homogenized), but this pattern was only seen when accounting for species presence/absence. We did not observe consistent patterns of divergence between the assemblages in the eutrophying lakes and the low-nutrient reference site. Given the pervasive nature of fertilization and metal pollution, and the sensitivity of cladocerans to these factors, we suggest that many inhabited lake districts may already exhibit similar patterns of daphniid assemblage shifts.

U7 snRNA mutations in Drosophila block histone pre-mRNA processing and disrupt oogenesis

description: Metazoan replication-dependent histone mRNAs are not polyadenylated, and instead terminate in a conserved stem–loop structure generated by an endonucleolytic cleavage involving the U7 snRNP, which interacts with histone pre-mRNAs through base-pairing between U7 snRNA and a purine-rich sequence in the pre-mRNA located downstream of the cleavage site. Here we generate null mutations of the single Drosophila U7 gene and demonstrate that U7 snRNA is required in vivo for processing all replication-associated histone pre-mRNAs. Mutation of U7 results in the production of poly A+ histone mRNA in both proliferating and endocycling cells because of read-through to cryptic polyadenylation sites found downstream of each Drosophila histone gene. A similar molecular phenotype also results from mutation of Slbp, which encodes the protein that binds the histone mRNA 3′ stem–loop. U7 null mutants develop into sterile males and females, and these females display defects during oogenesis similar to germ line clones of Slbp null cells. In contrast to U7 mutants, Slbp null mutations cause lethality. This may reflect a later onset of the histone pre-mRNA processing defect in U7 mutants compared to Slbp mutants, due to maternal stores of U7 snRNA. A double mutant combination of a viable, hypomorphic Slbp allele and a viable U7 null allele is lethal, and these double mutants express polyadenylated histone mRNAs earlier in development than either single mutant. These data suggest that SLBP and U7 snRNP cooperate in the production of histone mRNA in vivo, and that disruption of histone pre-mRNA processing is detrimental to development.
Beyond Wilson-Cowan dynamics: oscillations and chaos without inhibition

description: Fifty years ago, Wilson and Cowan developed a mathematical model to describe the activity of neural populations. In this seminal work, they divided the cells in three groups: active, sensitive and refractory, and obtained a dynamical system to describe the evolution of the average firing rates of the populations. In the present work, we investigate the impact of the often neglected refractory state and show that taking it into account can introduce new dynamics. Starting from a continuous-time Markov chain, we perform a rigorous derivation of a mean-field model that includes the refractory fractions of populations as dynamical variables. Then, we perform bifurcation analysis to explain the occurance of periodic solutions in cases where the classical Wilson-Cowan does not predict oscillations. We also show that our mean-field model is able to predict chaotic behavior in the dynamics of networks with as little as two populations.

description: The automatic early diagnosis of prodromal stages of Alzheimer's disease is of great relevance for patient treatment to improve quality of life. We address this problem as a multi-modal classification task. Multi-modal data provides richer and complementary information. However, existing techniques only consider either lower order relations between the data and single/multi-modal imaging data. In this work, we introduce a novel semi-supervised hypergraph learning framework for Alzheimer's disease diagnosis. Our framework allows for higher-order relations among multi-modal imaging and non-imaging data whilst requiring a tiny labelled set. Firstly, we introduce a dual embedding strategy for constructing a robust hypergraph that preserves the data semantics. We achieve this by enforcing perturbation invariance at the image and graph levels using a contrastive based mechanism. Secondly, we present a dynamically adjusted hypergraph diffusion model, via a semi-explicit flow, to improve the predictive uncertainty. We demonstrate, through our experiments, that our framework is able to outperform current techniques for Alzheimer's disease diagnosis.

Water Management: Pragmatic and ethical issues for species-inclusive and sustainable water policies
Creators: name: Kopnina, Helen
name: Strang, Veronica
Publisher: name: Visions for Sustainability
Year: 2022

description: The Leaders’ Pledge for Nature highlights the fact that since ecosystems underpin human well-being, we need to ‘recognize that the business case for biodiversity is compelling’. In this article we argue that, in all areas of water management, there is an urgent need for a paradigmatic and practical shift to species-inclusive and sustainable water policies and practices. We believe that policies prioritizing human interests inevitably promote unsustainable forms of water management and use. This article outlines an alternative vision based on the ‘Half-Earth’ (Wilson 2016) perspective, emerging from the ‘nature needs half’ or NNH movement. NNH researchers state that to maintain viable long-term populations of most of Earth's remaining species, approximately 50% of landscapes and seascapes need to be protected from intensive human economic use. However, while terrestrial conservation measures are prominent in the literature, a Half-Earth, of fresh and sea waterscapes is rarely discussed. Our article addresses this omission. We ask what species-inclusive policies and practices in marine and freshwater conservation would look like? If government policy-makers direct spending towards sustainable fishing, for example, how can this align with a focus on marine biodiversity? How can an ecocentric view tackle the illicit finance involved in illegal fishing? How do we marry up existing conservation policy, which is people-centric, with ecocentric 'nature positivity'? We reflect on possible implications for ecocentric water management and sustainable water policies and practices from examples of non-governmental organizations (NGOs) Sea Shepherd and Greenpeace. We also note the potential for Strang’s proposed ‘re-imagined communities’ approach to be applied to river catchment management, providing a conceptual model for rebalancing wider decision-making processes to include non-human needs and interests.
