description: Decaying coarse woody debris can affect the underlying soil either by augmenting nutrients that can be exploited by tree roots, or by diminishing nutrient availability through stimulation of microbial nutrient immobilization. We analyzed C, N, microbial biomass C and root length in closely paired soil samples taken under versus 20–50 cm away from large trunks of two species felled by Hugo (1989) and Georges (1998) three times during wet and dry seasons over the two years following the study conducted by Georges. Soil microbial biomass, % C and % N were significantly higher under than away from logs felled by both hurricanes (i.e., 1989 and 1998), at all sampling times and at both depths (0–10 and 10–20 cm). Frass from wood boring beetles may contribute to early effects. Root length was greater away from logs during the dry season, and under logs in the wet season. Root length was correlated with microbial biomass C, soil N and soil moisture (R = 0.36, 0.18, and 0.27, respectively; all p values < 0.05). Microbial biomass C varied significantly among seasons but differences between positions (under vs. away) were only suggestive. Microbial C was correlated with soil N (R = 0.35). Surface soil on the upslope side of the logs had significantly more N and microbial biomass, likely from accumulation of leaf litter above the logs on steep slopes. We conclude that decaying wood can provide ephemeral resources that are exploited by tree roots during some seasons.

Synthesis of very-long-chain bifunctional and isotope-labeled compounds for biochemical investigations into novel compounds in plant cuticular waxes
Creators: name: Peng, Chen
Publisher: name: University of British Columbia
Year: 2012

description: Plant cuticles are the interface for plant-environment interactions, and the first barrier protecting plants from environmental stresses such as water loss and pathogens. Structurally, the cuticle consists of a hydrophobic polymer lattice, cutin, and cuticular waxes deposited inside and outside cutin. The major components of the cuticular waxes are aliphatics derived from very-long-chain (VLC) fatty acids, such as alkanes and aldehydes. Besides compounds with primary functionalities, some compounds with two or more functional groups have also been identified in cuticular waxes. However, only limited knowledge about them has been acquired so far. The current work was to identify novel 1,2- and 1,3-bifunctional wax compounds from various plant species, in order to expand our current understanding of their structure, biosynthesis and function in plant cuticles. Synthetic methods were first developed to produce various VLC 1,2- and 1,3-bifunctionalized standard compounds for current and future structure elucidation studies. Unknown compounds found in Cosmos bipinnatus petal wax were identified as alkane-1,2-diol monoacetates by GC-MS, with chain lengths ranging from C20 to C24. The ratio between the primary and the secondary monoacetates was quantified to be 3:5, as opposed to the thermodynamic equilibrium ratio of 7:3. Novel β-hydroxy acid methyl esters were also identified from Aloe arborescens leaf wax, with chain lengths ranging from C26 to C30. In addition, two NMR-based methods were established to study the stereoconfigurations of alkane-1,2-diols from C. bipinnatus petal wax, and the carbons bearing secondary hydroxyl functionality were determined to have predominately the R-configuration. Apart from the research on bifunctional compounds, synthetic methods to produce β-deuterium labeled VLC substrates were also established. The resulting C30 fatty acid methyl ester was double-labeled and can be used directly or indirectly as substrates in future biochemical assays. At last, the hypothetic substrate for the CER1 enzyme implicated in wax alkane biosynthesis, C30 aldehyde, was synthesized and used in in vivo assays with heterologously expressed protein.

description: Ghost-free Infinite Derivative Gravity (IDG) is a modifed gravity theory

      which can avoid the singularities predicted by General Relativity.

      This thesis examines the effect of IDG on four areas of importance

      for theoretical cosmologists and experimentalists. First, the
      gravitational

      potential produced by a point source is derived and compared

      to experimental evidence, around both Minkowski and (Anti)

      de Sitter backgrounds. Second, the conditions necessary for avoidance

      of singularities for perturbations around Minkowski and (Anti)

      de Sitter spacetimes are found, as well as for background Friedmann-

      Robertson-Walker spacetimes. Third, the modification to perturbations

      during primordial inflation is derived and shown to give a constraint

      on the mass scale of IDG, and to allow further tests of the

      theory. Finally, the effect of IDG on the production and propagation

      of gravitational waves is derived and it is shown that IDG gives

      almost precisely the same predictions as General Relativity for the

      power emitted by a binary system.

description: Nanoporous anatase TiO2 rods and rutile TiO2 chrysanthemums were successfully synthesized via a simple ethylene glycol-mediated synthesis route. Their morphologies, phase compositions and components were characterized by SEM, TEM, Raman and IR, respectively. The results show that a self-assembly growth takes place in the calcination under vacuum, which makes the titanium glycolate rods transform into rutile TiO2/C chrysanthemums rather than anatase TiO2 rods. It also indicates that the carbon plays an important role in the phase transition process which promotes the phase transition to rutile TiO2 at a lower temperature (400 oC). It provides a new approach to prepare nanoporous rutile TiO2 nanomaterials under low temperature.

description: Vulnerability mapping reveals areas that are likely to be at greater risk of climate-related disasters in the future. Through integration of climate, biophysical, and socioeconomic data in an overall vulnerability framework, so-called “hotspots” of vulnerability can be identified. These maps can be used as an aid to targeting adaptation and disaster risk management interventions. This paper reviews vulnerability mapping efforts in West Africa conducted under the USAID-funded African and Latin American Resilience to Climate Change (ARCC) project. The focus is on the integration of remotely sensed and socioeconomic data. Data inputs included a range of sensor data (e.g., MODIS NDVI, Landsat, SRTM elevation, DMSP-OLS night-time lights) as well as high-resolution poverty, conflict, and infrastructure data. Two basic methods were used, one in which each layer was transformed into standardized indicators in an additive approach, and another in which remote sensing data were used to contextualize the results of composite indicators. We assess the benefits and challenges of data integration, and the lessons learned from these mapping exercises.

description: Given photovoltaics’ (PVs) constant improvements in terms of material usage and energy efficiency, this paper provides a timely update on their life-cycle energy and environmental performance. Single-crystalline Si (sc-Si), multi-crystalline Si (mc-Si), cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS) systems are analysed, considering the actual country of production and adapting the input electricity mix accordingly. Energy pay-back time (EPBT) results for fixed-tilt ground mounted installations range from 0.5 years for CdTe PV at high-irradiation (2300 kWh/(m2·yr)) to 2.8 years for sc-Si PV at low-irradiation (1000 kWh/(m2·yr)), with corresponding quality-adjusted energy return on investment (EROIPE-eq) values ranging from over 60 to ~10. Global warming potential (GWP) per kWhel averages out at ~30 g(CO2-eq), with lower values (down to ~10 g) for CdTe PV at high irradiation, and up to ~80 g for Chinese sc-Si PV at low irradiation. In general, results point to CdTe PV as the best performing technology from an environmental life-cycle perspective, also showing a remarkable improvement for current production modules in comparison with previous generations. Finally, we determined that one-axis tracking installations can improve the environmental profile of PV systems by approximately 10% for most impact metrics.

description: We study the magnetic response of holographic superconductors exhibiting an insulating "normal" phase. These materials can be realized as a CFT compactified on a circle, which is dual to the AdS Soliton geometry. We study the response under i) magnetic fields and ii) a Wilson line on the circle. Magnetic fields lead to formation of vortices and allows one to infer that the superconductor is of type II. The response to a Wilson line is in the form of Aharonov-Bohm-like effects. These are suppressed in the holographic conductor/superconductor transition but, instead, they are unsuppressed for the insulator case. Holography, thus, predicts that generically insulators display stronger Aharonov-Bohm effects than conductors. In the fluid-mechanical limit the AdS Soliton is interpreted as a supersolid. Our results imply that supersolids display unsuppressed Aharonov-Bohm (or "Sagnac") effects - stronger than in superfluids.

The role of OH in the chemical evolution of protoplanetary disks. I. The comet-forming region

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Context. Time dependent gas-grain chemistry can help us understand the layered structure of species deposited onto the surface of grains during the lifetime of a protoplanetary disk. The history of trapping important quantities of carbon- and oxygen-bearing molecules onto the grains is of special significance for the formation of more complex (organic) molecules on the surface of grains. Aims. Among other processes, cosmic ray-induced UV photo-processes can lead to the efficient formation of OH. Using a more accurate treatment of cosmic ray-gas interactions for disks, we obtain an increased cosmic ray-induced UV photon flux of 3.8x10^5 photons cm^-2s^-1 for a cosmic-ray ionization rate of H2 value of 5x10^-17 s^-1 (compared to previous estimates of 10^4 photons cm^-2s^-1 based on ISM dust properties). We explore the role of the enhanced OH abundance on the gas-grain chemistry in the midplane of the disk at 10 AU, which is a plausible location for comet formation. We focus on studying the formation/destruction pathways and timescales of the dominant chemical species. Methods. We solve the chemical rate equations based on a gas-grain chemical network and correcting for the enhanced cosmic rayinduced UV field. This field is estimated from an appropriate treatment of dust properties in a protoplanetary disk, as opposed to previous estimates that assume an ISM-like grain size distribution. We also explore the chemical effects of photo-desorption of water ice into OH+H. Results. Near the end of the disk's lifetime our chemical model yields H2O, CO, CO2 and CH4 ice abundances at 10 AU (consistent with a midplane density of 10^10 cm^-3 and a temperature of 20 K) that are compatible with measurements of the chemical composition of cometary bodies for a [C/O] ratio of 0.16. Such comparison provides constraints on the physical conditions in which comets were formed.

Underweight status, household food security and associated characteristics among women ≥18y in Bình Phước province, Vietnam
Creators: name: Brown, Matthew Ryan
Publisher: name: University of British Columbia
Year: 2013

description: Background: Chronic malnutrition among women is a significant issue in rice exporting Vietnam. In 2000, underweight prevalence (BMI<18.5 kg/m²) among women (20-49y) was 26.3% and was associated with maternal and infant mortality and intra-uterine-growth-restrition. Known risk factors of underweight are poverty, rural-living and ethnicity but are insufficient to explain the causes of these high rates. Food insecurity, nutritional knowledge, dietary diversity, and cultural dietary behaviours may contribute to underweight prevalence in Vietnam. The province of Bình Phước was selected to explore determinants of high underweight status in a productive agrarian region. Objective: The primary objective was to assess underweight status and household food insecurity among non-pregnant women in Bình Phước. Secondary regression analysis of both underweight status and household food insecurity determined associated risk factors including psychosocial dietary behaviours, household demographics, dietary diversity and nutrition knowledge. Methods: A cross-sectional survey was conducted among non-pregnant women (n=397),≥8y, in 10 villages. The Household-Food-Insecurity-Access-Scale (HFIAS) classified food insecurity and anthropometric data classified underweight. Further survey questions assessed dietary diversity, demographics, nutrition knowledge and dietary behaviours. Results: In 2006, 24.4% (97/397) of women were underweight (95% CI; [20.2 to 28.7]). Food insecurity (HFIAS) scores were 6.7 (5.7 SD) out of 27 classifying 51% (204/397) as having severe, 15% (61/397) as moderate and 19% (77/397) as mild food insecurity. Logistic regression predicting underweight (vs. non-underweight) found that participants with mild food insecurity had a one-in-three odds of being underweight compared with those severely food insecure (OR 0.35, 95% CI; [0.17 to 0.75], p<0.001). Participants with no children (<5y) had lower odds of underweight compared to participants with ≥2 children (<5y) (OR 0.30, 95% CI; [0.14 to 0.65], P<0.01). The odds of higher food insecurity was lower among participants with moderate nutrition knowledge (OR 0.52, [95%CI, 0.29 to 0.92], P<0.05), higher education (grade 7-9) (OR 0.59, [95%CI, 0.36 to 0.97], P<0.05) and higher dietary diversity (OR 0.32, [(95% CI; 0.18 to 0.58], P<0.001). Conclusion: High levels of underweight were associated with HFIAS food insecurity and with having higher numbers of children (<5y). Significant predictors of food insecurity were education, nutrition knowledge and dietary diversity.

description: Inherited retinal diseases, such as age-related macular degeneration and retinitis pigmentosa, are the leading cause of blindness in the developed world. Currently, treatments for these conditions are limited. Recently, considerable attention has been given to the possibility of using patient-specific induced pluripotent stem cells (iPSCs) as a treatment for these conditions. iPSCs reprogrammed from adult somatic cells offer the possibility of generating patient-specific cell lines in vitro. In this review, we will discuss the current literature pertaining to iPSC modeling of retinal disease, gene therapy of iPSC-derived retinal pigmented epithelium (RPE) cells, and retinal transplantation. We will focus on the use of iPSCs created from patients with inherited eye diseases for testing the efficacy of gene or drug-based therapies, elucidating previously unknown mechanisms and pathways of disease, and as a source of autologous cells for cell replacement.

description: We perform a numerical investigation of the thermodynamics during the collapse of a charged (complex) scalar field to a Reissner-Nordström (RN) black hole in isotropic coordinates. Numerical work on gravitational collapse in isotropic coordinates has recently shown that the negative of the total Lagrangian approaches the Helmholtz free energy F= E-TS of a Schwarzschild black hole at late times of the collapse (where E is the black hole mass, T the temperature and S the entropy). The relevant thermodynamic potential for the RN black hole is the Gibbs free energy G=E-TS-$Φ_H$ Q where Q is the charge and $Φ_H$ the electrostatic potential at the outer horizon. In charged collapse, there is a large outgoing matter wave which prevents the exterior from settling quickly to a static state. However, the interior region is not affected significantly by the wave. We find numerically that the interior contribution to the Gibbs free energy is entirely gravitational and accumulates in a thin shell just inside the horizon. The entropy is gravitational in origin and one observes dynamically that it resides on the horizon. We also compare the numerical value of the interior Lagrangian to the expected analytical value of the interior Gibbs free energy for different initial states and we find that they agree to within 10-13%. The two values are approaching each other so that their difference decreases with more evolution time.

description: This study focuses on those books pertaining to astrological and practical celestial pursuits that are listed in the inventory of manuscripts in the book treasury of the Topkapı Palace in Istanbul, commissioned by the Ottoman sultan Bayezid II from his royal librarian ʿAtufi in the year 908 (1502–3) and transcribed in a clean copy in 909 (1503–4). This unicum inventory preserved in the Oriental Collection of the Library of the Hungarian Academy of Sciences (Magyar Tudományos Akadémia Könyvtára Keleti Gyűjtemény, MS Török F. 59) records over 5,000 volumes, and more than 7,000 titles, on virtually every branch of human erudition at the time. The Ottoman palace library housed an unmatched encyclopedic collection of learning and literature; hence, the publication of this unique inventory opens a larger conversation about Ottoman and Islamic intellectual/cultural history. The very creation of such a systematically ordered inventory of books raises broad questions about knowledge production and practices of collecting, readership, librarianship, and the arts of the book at the turn of the fifteenth century.

description: The theoretically clean channel B+ -> tau+ nu shows a close to 3sigma discrepancy between the Standard Model prediction and the data. This in turn puts a strong constraint on the parameter space of a two-Higgs doublet model, including R-parity conserving supersymmetry. The constraint is so strong that it almost smells of fine-tuning. We show how the parameter space opens up with the introduction of suitable R-parity violating interactions, and release the tension between data and theory.

description: The suitability of turbine configurations to different wind resources has been traditionally restricted to considering turbines operating as standalone entities. In this paper, a framework is thus developed to investigate turbine suitability in terms of the minimum cost of energy offered when operating as a group of optimally-micro-sited turbines. The four major steps include: (i) characterizing the geographical variation of wind regimes in the onshore U.S. market; (ii) determining the best performing turbines for different wind regimes through wind farm layout optimization; (iii) developing a metric to quantify the expected market suitability of available turbine configurations; and (iv) exploring the best tradeoffs between the cost and capacity factor yielded by these turbines. One hundred thirty one types of commercial turbines offered by major global manufacturers in 2012 are considered for selection. It is found that, in general, higher rated power turbines with medium tower heights are the most favored. Interestingly, further analysis showed that “rotor diameter/hub height” ratios greater than 1.1 are the least attractive for any of the wind classes. It is also observed that although the “cost-capacity factor” tradeoff curve expectedly shifted towards higher capacity factors with increasing wind class, the trend of the tradeoff curve remained practically similar.

description: Background: Bisphosphonate-associated osteonecrosis of the jaws (MRONJ/BP-ONJ/BRONJ) is a commonly seen disease. During recent decades, major advances in diagnostics have occurred. Once the clinical picture shows typical MRONJ features, imaging is necessary to determine the size of the lesion. Exposed bone is not always painful, therefore a thorough clinical examination and radiological imaging are essential when MRONJ is suspected. Methods: In this paper we will present the latest clinical update on the imaging options in regard to MRONJ: X-ray/Panoramic Radiograph, Cone Beam Computed Tomography (CBCT) and Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Nuclear Imaging, Fluorescence-Guided Bone Resection. Conclusion: Which image modality is chosen depends not only on the surgeon’s/practitioner’s preference but also on the available imaging modalities. A three-dimensional imaging modality is desirable, and in severe cases necessary, for extended resections and planning of reconstruction.

description: A suggested solution to the dark energy problem is the void model, where accelerated expansion is replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially inhomogeneous background. This large scale inhomogeneity distorts the spherical Baryon Acoustic Oscillation feature into an ellipsoid which implies that the bump in the galaxy correlation function occurs at different scales in the radial and transverse correlation functions. We compute these for the first time, under the approximation that curvature gradients do not couple the scalar modes to vector and tensor modes. The radial and transverse correlation functions are very different from those of the concordance model, even when the models have the same average BAO scale. This implies that if void models are fine-tuned to satisfy average BAO data, there is enough extra information in the correlation functions to distinguish a void model from the concordance model. We expect these new features to remain when the full perturbation equations are solved, which means that the radial and transverse galaxy correlation functions can be used as a powerful test of the Copernican Principle.

description: To assess the relation between exposure to environmental tobacco smoke throughout life and lung cancer in lifetime nonsmokers, the authors conducted in-person interviews with 41 male and 69 female never-smoking lung cancer cases and 117 male and 187 female never-smoking controls between 1983 and 1990 as part of a hospital-based case-control study of tobacco-related cancers. Cases had newly diagnosed, histologically confirmed primary carcinoma of the lung. Controls were matched to cases on age (±5 years), sex, race, hospital, and year of interview. Subjects were asked about environmental tobacco smoke exposure in childhood, in adulthood at home, in different jobs, and in transportation and social situations. In addition to amount smoked by family members in the subject's presence, subjects were asked to rate the intensity of each exposure, and married subjects were asked whether their spouse smoked in the bedroom. Several independent indicators of exposure to smoking by spouses were strongly correlated, thereby increasing confidence in the classification of exposure status. The reproducibility of environmental tobacco smoke variables was good for qualitative measures (yes/no), in agreement with previous studies. There were few associations of exposure in specific settings with lung cancer. Males whose wives smoked had an odds ratio of 1.60 (95% confidence interval (Cl) 0.67-3.82) and females whose husbands smoked had an odds ratio of 1.08 (95% Cl 0.60-1.94). While this study had limited sample size, the pattern of odds ratios shows little indication of an association of environmental tobacco smoke with lung cancer in nonsmokers.

description: Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management options, it is important to understand the vegetation dynamics and the major drivers governing the observed conditions. This study uses data from 29 sentinel landscapes (4640 plots) across the southern Africa. We used T-Square distance method to sample trees. Allometric models were used to estimate aboveground tree biomass from which aboveground biomass carbon stock (AGBCS) was derived for each site. Results show average tree density of 502 trees·ha−1 with semi-arid areas having the highest (682 trees·ha−1) and arid regions the lowest (393 trees·ha−1). The overall AGBCS was 56.4 Mg·ha−1. However, significant site to site variability existed across the region. Over 60 fold differences were noted between the lowest AGBCS (2.2 Mg·ha−1) in the Musungwa plains of Zambia and the highest (138.1 Mg·ha−1) in the scrublands of Kenilworth in Zimbabwe. Semi-arid and humid sites had higher carbon stocks than sites in sub-humid and arid regions. Anthropogenic activities also influenced the observed carbon stocks. Repeated measurements would reveal future trends in tree cover and carbon stocks across different systems.
Genetic studies to discover common variants associated with epithelial ovarian cancer risk and variation in age of natural menopause
Creators: name: Earp, Madalene A
Publisher: name: University of British Columbia
Year: 2013

description: Background. Epithelial ovarian cancer (EOC) and age of natural menopause (ANM) are two complex traits impacting women’s health. ANM is also an important EOC risk factor. Insight into genetic factors influencing EOC and ANM could provide novel entry points for understanding EOC pathogenesis, and the normal process of ovarian aging. Methods. A two-stage genome-wide association study (GWAS) design using DNA pooling in Stage 1 was used to discover single nucleotide polymorphisms (SNPs) associated with histology-specific EOC risk, and population-specific variation in ANM. SNP-trait associations discovered in Stage 1 of these GWAS were replicated in two different consortia; EOC association in the Ovarian Cancer Association Consortium (OCAC), and ANM associations in the ReproGen Consortium. Results. Eight subtype-specific SNP-EOC associations discovery in Stage 1 of the EOC GWAS were replicated (unadjusted P <0.05) in the datasets of the OCAC: 4 in the mucinous subtype, 2 in the endometrioid and clear cell (ENCC) subtypes combined, and 2 in the low-malignancy potential (LMP) serous subtype. These associations did not achieve genome-wide significance (P < 5x10⁻⁸). However, several of the loci implicated by these SNPs harbour attractive candidate genes for ovarian cancer biology, including the mucinous locus harbouring RAD51B, the ENCC locus harbouring GRB10, and the LMP serous locus harbouring BPIL2/C22orf26. The GWAS of ANM performed in Iranian women revealed one SNP-trait association exclusive to this population (rs10140275; unadjusted P=4.0x10⁻⁴) and one shared with the European population (rs10840211). In the replication of European GWAS findings in Iranian women one SNP at the 20p12.3 locus was replicated (rs16991615, unadjusted P=0.02). SNPs tagging the 19q13.42 locus narrowly missed replication in our dataset (rs1172822, unadjusted P= 0.08). Conclusion. Eight SNP-EOC associations warrant further replication and/or fine-mapping in samples with reliable tumour information. These SNPs tag loci harbouring candidate genes involved in DNA repair, the PI3K/AKT pathway, and immune function, suggesting these pathways and processes may be important to the etiology of the rarer EOC subtypes. The generality of the European ANM GWAS findings in established in another human population (20p12.3). Further, one genetic variant influencing ANM in the Iranian population but not the European population is reported.

description: Poor school-functioning can be indicative of parent and adolescent mental health and adolescent behavior problems. This study examined 472 adolescents enrolled in the World Trade Center (WTC) Health Registry, with a two-step path analysis, using regression-based models, to unravel the relationships between parent and adolescent mental health, adolescent behavior problems, and adolescent unmet healthcare need (UHCN) on the outcome school-functioning. WTC exposure was associated with UHCN and parental mental health was a significant mediator. There was no evidence that family WTC exposure was associated with UHCN independent of its effect on parental mental health. For the second path, after accounting for the effects of adolescent mental health, behavioral problems, and UHCN, there remained a significant association between parental mental health and school-functioning. Interventions for poor school functioning should have multiple components which address UHCN, mental health, and behavioral problems, as efforts to address any of these alone may not be sufficient

Distribution of Latency-Constrained Tasks in Multi-Access Edge Computing Networks
Creators: name: Carlinet, Yannick
Publisher: name: Zenodo

description: Multi-Access Edge Computing (MEC) paradigm has been widely studied as a potential solution to cope with the challenges emerging from new generations of mobile networks. By processing applications' data closer to the users, service providers are able to offload origin servers and their underlying network infrastructure, which consequently reduces users' experienced latency. In this paper, we consider internet-based applications with strict latency tolerance which are primarily enabled by the MEC architecture. Moreover, nodes at the edge may host application-related tasks as well as assist in their provision. We formalize the Task Distribution Problem (TDP), where the objective is to maximize the overall Quality of Service (QoS) while ensuring that tasks' latency requirements are satisfied. The TD problem is modeled as an Integer Programming problem, taking into account three components: (i) tasks' priority assignment, (ii) placement and (iii) routing through the MEC network. We propose to approach the TDP through an approximation scheme, called Shortest-Flow Approximation (SFA), which considers predetermined network flows selected according to a Betweennessbased criterion. In our experiments, we first extract useful insights on the TDP that help characterize its solution. Then, we evaluate SFA's performance empirically across different experimental settings, showing numerical results confirming its proximity to the optimal solution.

description: We develop a simple treatment of a metamaterial perfect absorber (MPA) based on grating theory. We analytically prove that the condition of MPA requires the existence of two currents, which are nearly out of phase and have almost identical amplitude, akin to a magnetic dipole. Furthermore, we show that non-zero-order Bragg modes within the MPA may consume electromagnetic energy significantly.

description: The eclipses in binary stars give precise information of orbital period changes. Goodricke discovered the 2.867 days period in the eclipses of Algol in the year 1783. The irregular orbital period changes of this longest known eclipsing binary continue to puzzle astronomers. The mass transfer between the two members of this binary should cause a long-term increase of the orbital period, but observations over two centuries have not confirmed this effect. Here, we present evidence indicating that the period of Algol was 2.850 days three millenia ago. For religious reasons, the ancient Egyptians have recorded this period into the Cairo Calendar, which describes the repetitive changes of the Raging one. Cairo Calendar may be the oldest preserved historical document of the discovery of a variable star.

description: Hereditary hypertrichoses are a group of hair overgrowth syndromes that are extremely rare in humans. We have previously demonstrated that a position effect on TRPS1 is associated with hypertrichosis in humans and mice. To gain insight into the functional role of Trps1, we analyzed the late morphogenesis vibrissae phenotype of Trps1Δgt mutant mice, which is characterized by follicle degeneration after peg downgrowth has been initiated. We found that Trps1 directly represses expression of the hair follicle stem cell regulator Sox9 to control proliferation of the follicle epithelium. Furthermore, we identified a copy number variation upstream of SOX9 in a family with hypertrichosis that significantly decreases expression of the gene in the hair follicle, providing new insights into the long-range regulation of SOX9. Our findings uncover a novel transcriptional hierarchy that regulates epithelial proliferation in the developing hair follicle and contributes to the pathology of hypertrichosis.

description: The invariants of rank 2 Joyce-Song semistable pairs over a Calabi-Yau threefold were computed in arXiv:1101.2252, using the wall-crossing formula of Joyce-Song and Kontsevich-Soibelman. Such wall-crossing computations often depend on the combinatorial properties of certain elements of a Hall-algebra (these are the stack functions defined by Joyce). These combinatorial computations become immediately complicated and hard to carry out, when studying higher rank stable pairs with rank$>2$. The main purpose of this article is to introduce an independent approach to computation of rank 2 stable pair invariants, without applying the wallcrossing formula and rather by stratifying their corresponding moduli space and directly computing the weighted Euler characteristics of the strata. This approach may similarly be used to avoid complex combinatorial wallcrossing calculations in rank$>2$ cases.
