The radio structure of the peculiar narrow-line Seyfert 1 galaxy candidate J1100+4421

Narrow-line Seyfert 1 galaxies (NLS1) are an intriguing subclass of active galactic nuclei. Their observed properties indicate low central black hole mass and high accretion rate. The extremely radio-loud NLS1 sources often show relativistic beaming and are usually regarded as younger counterparts of blazars. Recently, the object SDSS J110006.07+442144.3 was reported as a candidate NLS1 source. The characteristics of its dramatic optical flare indicated its jet-related origin. The spectral energy distribution of the object was similar to that of the gamma-ray detected radio-loud NLS1, PMN J0948+0022. Our high-resolution European Very Long Baseline Interferometry Network observations at 1.7 and 5 GHz revealed a compact core feature with a brightness temperature of >~ 10^(10) K. Using the lowest brightness temperature value and assuming a moderate Lorentz factor of ~9 the jet viewing angle is <~ 26 deg. Archival Very Large Array data show a large-scale radio structure with a projected linear size of ~150 kpc reminiscent of double-sided morphology.
Surround&Squash: The Interstellar Medium around Scorpius Centaurus OB2

Context. Feedback by massive stars shapes the interstellar medium and is thought to influence subsequent star formation. Details of this process are under debate. Aims. We exploited observational constraints on stars, gas and nucleosynthesis ashes for the closest region of recent massive-star formation, Scorpius-Centaurus OB2, and combined them with 3D hydrodynamical simulations, in order to address physics and history for the case of the Scorpius-Centaurus superbubble. Methods. We used published cold gas observations through PLANCK survey data processing, HERSCHEL and APEX, continuum and molecular line observations. We analysed the Galactic All Sky Survey (GASS) to investigate shell structures in atomic hydrogen, and used HIPPARCOS and Gaia data in combination with interstellar absorption against stars to obtain new constraints for the distance to the Hi features. Hot gas is traced in soft X-rays via the ROSAT all sky survey. Nucleosynthesis ejecta from massive stars were traced with new INTEGRAL spectrometer observations via 26Al radioactivity. We also performed 3D hydrodynamical simulations for the Sco-Cen superbubble. Results. Soft X-rays and a now more significant detection of 26Al confirm recent (≈ 1 Myr ago) input of mass, energy and nucleosynthesis ejecta, likely by a supernova in the Upper Scorpius (USco) subgroup. We confirm a large supershell around the entire OB association and perform a 3D hydrodynamics simulations with a conservative massive star population that reproduces the morphology of the superbubble. High resolution GASS observations of a nested supershell reveal that it is filamentary possibly related to the Vishniac clumping instability, but molecular gas (Lupus I) is only present where the shell coincides with the connecting line between the subgroups of the OB association, suggesting a connection to the cloud, probably an elongated sheet, out of which the OB association formed. Stars have formed sequentially in the subgroups of the OB association and currently form in Lupus I. To investigate the impact of massive star feedback on extended clouds, we simulate the interaction of a turbulent cloud with the hot, pressurised gas in a superbubble. The hot gas fills the tenuous regions of the cloud and compresses the denser parts. Stars formed in these dense clumps would have distinct spatial and kinematic distributions. Conclusions. The combined results from observations and simulations are consistent with a scenario where dense gas was initially distributed in a band elongated in the direction now occupied by the OB association. Superbubbles powered by massive stars would then repeatedly break out of the elongated parent cloud, surround and squash the denser parts of the gas sheet and thus induce more star formation. The expected spatial and kinematic distribution of stars is consistent with observations of Sco-Cen. The scenario might apply to many similar regions in the Galaxy and also to AGN-related superbubbles.
Study the Heating Mechanisms of Temperature Controlled Microwave Closed System (TCMCS)

The efficiency of temperature controlled microwave closed system (TCMCS) on heating mechanism was investigated. Heating mechanism of TCMCS was studied on plant material (Nephrolepis biserrata) immersed in water, acetone, acetonitrile and ethanol at different microwave power level. The rising temperature of TCMCS was influenced by their dielectric, physical and heating properties of the solvents. After reaching the boiling point, the solvent density decreased and this factor affected in reducing of dielectric properties. Water which has lower mass heat capacity took time to rise a temperature as compared to acetone, acetonitrile and ethanol. The rate of heat generation and penetration depth was calculated. The decreasing of heat generation within radiation time is due to the decreasing dielectric properties of solvents with regards to temperature increase. The penetration depth at high microwave power is higher than at lower microwave power. As a polar solvent, water was efficiently absorb microwave energy and leads to efficient heating at 700Watt followed by 560>420>280>140Watts.This provides a qualitative understanding of microwave heating mechanism.
Title Demographic structure and overlapping generations : A simplerproof with more general conditions

d'Albis (2007) considers a continuous-time general equilibrium overlapping-generations model with age-specific mortality rates. His proof of the existence and uniqueness of the steady-state equilibrium, which can be extended to other overlapping-generations models, relies on the shape of a function that appears in the equation defining the equilibrium. By focusing on the mean age as a function of the stable population growth rate instead of the function used in d'Albis (2007), we provide a simpler proof with more general conditions. We also obtain useful properties about the first and second derivatives of the mean age function that can be applied in future work. JEL Classification Numbers: E13; E21; J10
SCALE-Sim: Systolic CNN Accelerator

Systolic Arrays are one of the most popular compute substrates within Deep Learning accelerators today, as they provide extremely high efficiency for running dense matrix multiplications. However, the research community lacks tools to insights on both the design trade-offs and efficient mapping strategies for systolic-array based accelerators. We introduce Systolic CNN Accelerator Simulator (SCALE-Sim), which is a configurable systolic array based cycle accurate DNN accelerator simulator. SCALE-Sim exposes various micro-architectural features as well as system integration parameters to the designer to enable comprehensive design space exploration. This is the first systolic-array simulator tuned for running DNNs to the best of our knowledge. Using SCALE-Sim, we conduct a suite of case studies and demonstrate the effect of bandwidth, data flow and aspect ratio on the overall runtime and energy of Deep Learning kernels across vision, speech, text, and games. We believe that these insights will be highly beneficial to architects and ML practitioners.
Surface displacements on faults triggered by slow magma transfers between dyke injections in the 2005–2010 rifting episode at Dabbahu–Manda–Hararo rift (Afar, Ethiopia)

The rifting episode that occurred in Dabbahu–Manda–Hararo (Ethiopia) between 2005 and 2010 during which 14 dyke intrusions were emitted, was a unique opportunity to study interactions between tectonic deformation and magmatic processes. While magmatism has been shown to control primarily the spatial and temporal distribution of dyke intrusions during this accretion sequence, the role of faults in accommodating plate spreading in rift segments is poorly understood. During interdyking periods, transient ground deformation due to magma movement is generally observed. Investigating such a small-scale deformation and in particular the movement along faults during these periods will help understanding the factors that trigger fault movement in magmatic rifts. We analyse fault activity during three interdyking periods: 2006 December–June (d0–d1), 2007 January–July (d5–d6) and 2009 November–January (d10– d11). The time–space evolution of surface displacements along ∼700 faults is derived from pairs of ascending and descending SAR interferograms. Surface slip distributions are then compared with codyking ground deformation fields. The results show that faults are mainly activated above the areas affected by magma emplacement during interdyking periods. A detailed analysis of brittle deformation during the six months following the 2005 September intrusion shows asymmetric deformation on the rift shoulders, with significant opening on faults located to the west of the dyke. We explain this feature by the activation of westward dipping pre-existing faults, with block rotations in between. In addition, we observe that the strip encompassing the activated faults narrows by 30 per cent from co-to interdyking period. This suggests that magma keeps migrating to shallower depths after the dyke intrusion. During a rifting episode, activation of faults in a pre-existing fracture network therefore seems to be mainly controlled by deep magma processes.
Modeling Municipal Yields with (and without) Bond Insurance

We develop an intensity-based model of municipal yields, making simultaneous use of the credit default swap premiums of the insurers and both insured and uninsured municipal bond transactions. We estimate the model individually for 61 municipal issuers by exploiting the dramatic decline in credit quality of the bond insurers from July 2007 to June 2008, and decompose the municipal yield spread based on the estimated parameters. The decomposition reveals a dominant role of the liquidity component as well as interactions between liquidity and default similar to those modeled by Chen et al. [Chen H, Cui R, He Z, Milbradt K (2018) Quantifying liquidity and default risks of corporate bonds over the business cycle. Rev. Financial Stud. 31(3):852–897. ] for corporate bonds. Toward the end of the sample period, our model also reproduces the “yield inversion” phenomenon documented in the literature. This paper was accepted by Neng Wang, finance.
‘Close to the city centre, close to the university’. Are there symptoms of studentification in Gdańsk, Poland?

Abstract Students are increasingly recognised as important actors of urban change in contemporary cities. The article presents an analysis of incipient studentification processes in Gdańsk. Its general aim is to reveal patterns of students’ presence and activity which translate into spatial and socio-economic transformations of a post-socialist city at the level of neighbourhoods. The study consists of a survey on students’ residential behaviour, complemented by field and desk research. According to the results, due to the fact that Polish students’ housing and lifestyle choices are limited by their low purchasing power, student-dedicated services have a rather negative impact on the quality of urban space. Furthermore, under these conditions studentification may not be regarded as a stimulus to the gentrification process, which is rather driven by hipsters and affluent foreign students.
Effect of humic acid coating on arsenic adsorption on ferrihydrite-kaolinite mixed systems

The reactivity of the colloids formed in soil environments results from complex interactions between clay minerals, (oxy)hydroxides and organic matter of soils. The adsorption/desorption equilibria and kinetics of anionic and cationic species on/from natural colloids could substantially differ compared with their interaction with pure minerals. The objective of this study was to investigate the arsenite and arsenate equilibria and the kinetics of arsenite adsorption on ferrihydrite-coated kaolinite as influenced by the presence of humic acid coverage. The Langmuir adsorption maximum and affinity of arsenite and arsenate adsorption on the kaolinite-ferrihydrite system was reduced by the presence of the humic acid. The enthalpy of adsorption on the kaolinite-ferrihydrite system, measured with isothermal titration calorimetry, was –24.4 kJ mol–1 for arsenite and –39.9 kJ mol–1 for arsenate, and was only slightly decreased by the humic acid coating. The kinetics of arsenite adsorption was substantially influe.
T-qPCR-based microneutralization assay for human cytomegalovirus sing fibroblasts and epithelial cells

Human cytomegalovirus (HCMV) is a leading cause of congenital infection that can result in serious disabilities in affected children. To facilitate HCMV vaccine development, a microscale neutralization assay based on reverse transcription quantitative PCR (RT-qPCR) was developed to quantify HCMV-neutralizing antibodies. Our approach relies on the generation of crude lysates from virus-infected cells that are amenable to direct analysis by RT-qPCR, thereby circumventing rate-limiting procedures associated with sample RNA extraction and purification. By serial passaging of the laboratory HCMV strain AD169 in epithelial cells (ARPE-19), a revertant virus with restored epithelial cell tropism, designated AD169wt131, was obtained. AD169 and AD169wt131 were evaluated in both epithelial cells (ARPE-19) and fibroblasts (MRC-5) by one-step RT-qPCR targeting the immediate-early gene IE1 transcript of HCMV. Expression kinetics indicated that RT-qPCR assessment could be conducted as early as 6 h post-infection. Human serum samples (n = 30) from healthy donors were tested for HCMV-specific IgG using a commercially available ELISA and for HCMV-neutralizing activity using our RT-qPCR-based neutralization assay. In agreement with the ELISA results, higher neutralizing activity was observed in the HCMV IgG seropositive group when compared with the HCMV IgG seronegative group. In addition, HCMV IgG seropositive human sera exhibited higher neutralizing titers using epithelial cells compared with using fibroblasts (geometric mean titers of 344 and 8 in ARPE-19 cells and MRC-5 cells, respectively). Our assay was robust to variation in input virus dose. In addition, a simple lysis buffer containing a non-ionic detergent was successfully demonstrated to be a less costly alternative to commercial reagents for cell-lysate preparation. Thus, our rapid HCMV neutralization assay may be a straightforward and flexible high-throughput tool for measuring antibody responses induced by vaccination and natural infection.

A tight kernel for computing the tree bisection and reconnection distance between two phylogenetic trees

In 2001 Allen and Steel showed that, if subtree and chain reduction rules have been applied to two unrooted phylogenetic trees, the reduced trees will have at most 28k taxa where k is the TBR (Tree Bisection and Reconnection) distance between the two trees. Here we reanalyse Allen and Steel's kernelization algorithm and prove that the reduced instances will in fact have at most 15k-9 taxa. Moreover we show, by describing a family of instances which have exactly 15k-9 taxa after reduction, that this new bound is tight. These instances also have no common clusters, showing that a third commonly-encountered reduction rule, the cluster reduction, cannot further reduce the size of the kernel in the worst case. To achieve these results we introduce and use "unrooted generators" which are analogues of rooted structures that have appeared earlier in the phylogenetic networks literature. Using similar argumentation we show that, for the minimum hybridization problem on two rooted trees, 9k-2 is a tight bound (when subtree and chain reduction rules have been applied) and 9k-4 is a tight bound (when, additionally, the cluster reduction has been applied) on the number of taxa, where k is the hybridization number of the two trees.
Influence of Management Practices on Distribution of Fungicides in Golf Course Turf

2523 Fungicides are applied to golf course turf to limit disease development and improve turf quality. Most often, they are applied as dilute sprays with a water volume equivalent to 408 to 815 L ha–1 (1–2 gal per 1000 ft2). This arrangement is apparently ideal for protecting infection-prone leaves and shoots, based on the great success achieved with many fungicides against a broad spectrum of foliar pathogens (Latin, 2011). Fungicide sprays targeting root diseases frequently do not achieve such satisfactory results. Since root pathogens reside below turf surfaces, and because fungicides do not move downward through plant tissues, delivery of effective concentrations of fungicides to protect against root infection is a challenge. In many cases, attempts to control root diseases such as summer patch (caused by Magnaporthe poae), necrotic ring spot (caused by Ophiosphaerella korrae), take all patch (caused by Gaeumannomyces graminis), and spring dead spot (caused by Ophiosphaerella herpotricha) with fungicides are met with unsatisfactory results. To address this situation, when fungicides are targeted toward root diseases, recommendations often include increasing spray water volume 815 to 1630 L ha–1 (2–4 gal per 1000 ft2), or applying irrigation immediately after the sprayer exits the site. Additionally, some researchers have experimented with injection of fungicides into the profile (Fidanza et al., 2005), or by using wetting agents to facilitate fungicide movement. Use of wetting agents—surfactants designed to cause liquid to spread more easily across or penetrate into the surface of a solid—has become a standard practice in golf turf management (Karnok et al., 2004; Zontek and Kostka, 2012). Wetting agents are recommended to improve water infiltration and possibly facilitate downward movement of fungicides. Most research on the use of wetting agents to improve disease control has been conducted with fairy ring. In general, results show significant reductions in symptom expression associated with the addition of a wetting agent to the fungicide program, whether included as a tank-mix or applied prior to the fungicide spray (Fidanza et al., 2001, 2007; Stiles et al., 2007). In some cases, a wetting agent alone resulted in significant improvements in turf quality (Fidanza and Bagwell, 2005; Miller et al., 2012). This is not unexpected since, in the case of type I fairy ring, colonization of turf by fairy ring fungi creates a hydrophobic soil condition, which deprives plant roots of water, often to the Influence of Management Practices on Distribution of Fungicides in Golf Course Turf
HER 2 and TP 53 in human breast cancer Studies of methods and prognostic value

Prognostic and predictive factors are needed for tailored therapy strategies, aimed at reducing breast cancer relapse and improving survival. The present arsenal of such factors is insufficient. The aims of this thesis were to study the TP53 gene, and the human epidermal growth factor receptor 2 (HER2), also known as c-erbB-2 and HER2/neu, in human breast cancer, especially in relation to outcome after tamoxifen therapy. In order to make the best out of the biological markers’ prognostic and predictive values, optimal methods for their determinations are required, and this is also addressed in the thesis. We found mutated TP53 to be associated with worse outcome after adjuvant chemotherapy (CMF), but to be of no statistically significant importance with regard to the outcome of adjuvant tamoxifen. However, in the total patient population, women with wild type TP53 tumours had better survival compared with women whose tumours were TP53 mutated. We used sequenced-based methodology for analysis of all TP53 exons, based on indications that this method is superior to immunohistochemistry IHC in prognostication of breast cancer relapse and survival. The monoclonal antibody trastuzumab, directed against HER2, is one of many examples of emerging targeting therapies, of which tamoxifen was the first. We describe the first patients in Sweden who received trastuzumab on a named patient basis, all with advanced breast cancer failing on conventional therapy. The previously demonstrated efficacy and acceptable toxicity in randomised studies were confirmed in our small population-based patient cohort. Endocrine therapy with tamoxifen, mediating both anti-oestrogen, and oestrogen-like effects, has been used for more than three decades. Subsequently, tamoxifen resistance is a problem for a large cohort of breast cancer patients. Preclinical as well as clinical studies have hypothesised HER2 to be involved in tamoxifen resistance through cross-talk signalling with the oestrogen receptor, via the mitogen activated protein kinase, extra cellular regulated kinases 1 and 2 (ERK1/2) pathway. We confirmed HER2 to be associated with worse outcome after tamoxifen therapy while, in contrast to other studies, we found that activated ERK1/2 immunohistochemical staining, prognosticate better outcome. The increasing number of patients eligible for trastuzumab therapy requires reproducible, costeffective, and high throughput assays for HER2 determinations. Immunohistochemistry and fluorescence in situ hybridisation are the most frequently used methods for evaluation of HER2 status. We demonstrate quantitative real-time PCR and an RNA expression-based methodology to generate high-quality HER2 assessments with equivalent, and in some aspects improved results, compared with immunohistochemistry and fluorescence in situ hybridisation/chromogenic in situ hybridisation.
Practice makes efficient: Cortical alpha oscillations mediate improved golf putting performance

Practice of a motor skill results in improved performance and decreased movement awareness. The psychomotor efﬁciency hypothesis proposes that the development of motor expertise through practice is accompanied by physiological reﬁnements whereby irrelevant processes are suppressed and relevant processes are enhanced. The present study employed a test–retest design to evaluate the presence of greater neurophysio- logical efﬁciency with practice and mediation analyses to identify the factors accounting for performance improvements, in a golf putting task. Putting performance, move- ment-speciﬁc conscious processing, electroencephalographic alpha power and alpha connectivity were measured from 12 right-handed recreational golfers (age: M (cid:2) 21 years; handicap: M (cid:2) 23) before and after 3 practice sessions. As expected, performance improved and conscious processing decreased with training. Mediation analyses revealed that improvements in performance were partly attributable to increased regional gating of alpha power and reduced cross-regional alpha connectivity. How- ever, changes in conscious processing were not associated with performance improvements. Increased efﬁciency was manifested at the neurophysiological level as selective inhibition and functional isolation of task-irrelevant cortical regions (temporal regions) and concomitant functional activation of task-relevant regions (central regions). These ﬁndings provide preliminary evidence for the development of greater psychomotor efﬁciency with practice in a precision aiming task.
