Vertical partial frontolateral laryngectomy with simultaneous pedunculated sternothyroid muscle flap reconstruction of the vocal fold – surgical procedure and treatment outcomes
Authors: Jurek-Matusiak Olga , Wójtowicz Piotr , Szafarowski Tomasz , Krzeski Antoni
Published: March 2018

Purpose of the study: The aim of the study was to present the treatment outcomes after vertical partial laryngectomy
with or without pedunculated sternothyroid muscle flap reconstruction following the resection of neoplasm-infiltrated
vocal fold. The procedure was used in a patient with glottic cancer. Oncological outcomes, morphology of neo-vocal
fold and the act of swallowing were evaluated.
Material and methods: 45 patients with T1-T2 glottic cancer were subjected to vertical partial laryngectomy with 26
patients undergoing a procedure with pedunculated sternothyroid muscle flap reconstruction and the remaining 19
patients undergoing a procedure without such a reconstruction. Two female and 43 male patients aged 35-82 years
(mean age of 62.5 years) were enrolled in the study. Local tumor spread and the condition of reconstructed vocal fold
were assessed in sequential videofiberoscopy examination conducted each month after surgery whereas the regional
spread was assessed in ultrasound scans. Postoperative aspiration was graded according to the Pearson’s scale.
Results: Six patients experienced local recurrence while 2 patients experienced regional recurrence of the tumor. The
pedunculated sternothyroid muscle flap neo-fold was structurally resemblant of the non-affected vocal fold. Episodic,
daily dysphagia was observed in 1 patient while normal act of swallowing with no Pearson’s scale symptoms was observed
in the remaining 44 patients. No necrosis of pedunculated flap was observed.
Conclusions: Vertical partial laryngectomy with or without pedunculated sternothyroid muscle flap reconstruction is a good
method for the treatment of low- or intermediate-stage glottic cancer, especially when endoscopic access to the tumor is
limited and when CO2 laser cannot be used. No significant functional disorders were observed in operated larynges.

Os elementos constituintes da rede hidrográfica que compõem a superfície terrestre são fundamentais na investigação da morfogênese e morfodinâmica das formas de relevo. Nesse contexto se destacam as rupturas de declividade – os knickpoints – presentes nos perfis longitudinais dos principais afluentes do trecho centro-sul do divisor hidrográfico entre as bacias dos rios das Velhas e Paraopeba, em Minas Gerais. Na investigação desses knickpoints, objeto de análise neste trabalho, foram empregados na identificação da geometria das rupturas por modelos digitais de elevação, imagens orbitais disponibilizadas no Google Earth Pro, fotografias arquivadas no Panoramio e vídeos compartilhados pela plataforma Youtube. Os resultados indicaram rupturas que geram cachoeiras, corredeiras, além de alguns knickpoints utilizados para a construção de barragens. Esse conjunto de recursos se revelou eficiente na identificação e caracterização de knickpoints em canais fluviais, bem como exerceu papel fundamental no planejamento de trabalhos de campo, conduzidos a posteriori.

Abstract

The elements of the hydrographic network that make up the terrestrial surface are fundamental in the investigation of the morphogenesis and morphodynamics of the relief forms. In this context, the slope ruptures - the knickpoints - present in the longitudinal profiles of the main tributaries of the central-south section of the hydrographic divisor between the Velhas and Paraopeba river basins in Minas Gerais.  In the investigation of these knickpoints, object of analysis in this work, were used to identify the geometry of the ruptures by digital elevation models, orbital images available in Google Earth Pro, photographs archived in the Panoramio and videos shared by the Youtube platform. The results indicate ruptures that generate waterfalls, stretches of fast flow, and some knickpoints used for dam construction. This set of resources proved efficient in the identification and characterization of knickpoints in fluvial channels, as well as played a fundamental role in the planning of fieldwork, conducted in the future.

Brexit Populism: The Thick (and Thin) of It
Authors: Guderjan Marius , Wilding Adrian
Published: March 2018

On 24 June 2016, a narrow majority of citizens of the United Kingdom voted to leave the European Union, a decision which has exposed deep divisions in British society. This article analyses the extent to which the campaign to leave the EU and its aftermath can be explained in terms of existing definitions of ‘populism’. It distinguishes between a ‘thin’ and ‘thick’ ideology of populism. Whereas the ‘thin’ ideology refers to a specific political method or style, one which claims to represent the ‘true people’ against a ruling elite, the ‘thick’ ideology focuses on substantial ideological elements, e.g. authoritarian and nationalist worldviews. The paper demonstrates that the Brexit campaign has been dominated by exclusive, right-wing populist ideas. In order to understand the appeal of populist parties and movements in the UK, the paper explores the multi-layered factors that have led to widespread support for the anti-European and anti-immigration politics. It argues that a mix of economic, political and cultural disenfranchisement is a root cause of the vote for Brexit. In this light, the Brexit rhetoric of ‘taking back control’ can be interpreted as a (problematic) attempt to overcome disenfranchisement.

Published: March 2018

Motivated by a desire to curb "predatory" publishing, we created FlourishOA, a one-stop shop for authors, publishers, funders, librarians, and policy makers to find high-quality, cost-effective Open Access (OA) journals. FlourishOA provides Article Processing Charge and Article Influence (AI) score data for OA journals. AI scores are retrieved from InCites Journal Citations Reports (JCR). However, the FlourishOA database contains thousands of journals not indexed in JCR. In order to provide users with more data, our team gathered five years of citation counts from the Microsoft Academic Graph database via Microsoft Cognitive Services Academic Knowledge API and used a log-transformed linear regression to predict over 2,500 additional 2015 AI scores.
Deep learning for conflicting statements detection in text
Authors: Lingam Vijay , Bhuria Simran , Nair Mayukh , Gurpreetsingh Divij , Goyal Anjali , Sureka Ashish
Published: March 2018

Background. Automatic contradiction detection or conflicting statements detection in text consists of identifying discrepancy, inconsistency and defiance in text and has several real world applications in questions and answering systems, multi-document summarization, dispute detection and finder in news, and detection of contradictions in opinions and sentiments on social media. Automatic contradiction detection is a technically challenging natural language processing problem. Contradiction detection between sources of text or two sentence pairs can be framed as a classification problem.

Methods. We propose an approach for detecting three different types of contradiction: negation, antonyms and numeric mismatch. We derive several linguistic features from text and use it in a classification framework for detecting contradictions. The novelty of our approach in context to existing work is in the application of artificial neural networks and deep learning. Our approach uses techniques such as Long short-term memory (LSTM) and Global Vectors for Word Representation (GloVe). We conduct a series of experiments on three publicly available dataset on contradiction detection: Stanford dataset, SemEval dataset and PHEME dataset. In addition to existing dataset, we also create more dataset and make it publicly available. We measure the performance of our proposed approach using confusion and error matrix and accuracy.

Results. There are three feature combinations on our dataset: manual features, LSTM based features and combination of manual and LSTM features. The accuracy of our classifier based on both LSTM and manual features for the SemEval dataset is 91.2%. The classifier was able to correctly classify 3204 out of 3513 instances. The accuracy of our classifier based on both LSTM and manual features for the Stanford dataset is 71.9%. The classifier was able to correctly classify 855 out of 1189 instances. The accuracy for the PHEME dataset is the highest across all datasets. The accuracy for the contradiction class is 96.85%.

Discussion. Experimental analysis demonstrate encouraging results proving our hypothesis that deep learning along with LSTM based features can be used for identifying contradictions in text. Our results shows accuracy improvement over manual features after applying LSTM based features. The accuracy results varies across datasets and we observe different accuracy across multiple types of contradictions. Feature analysis shows that the discriminatory power of the five feature varies.

Published: March 2018

In this paper the results of a manipulative experiment aimed to evaluate the interactive short- and long-term effect of three different stressors, herbivory, nutrient and mucilage, on a macroalgal assemblage are presented. The experiment was conducted in Tavolara Punta Coda Cavallo Marine Protected Area during a bloom of the benthic mucilage-producing microalga Chrysophaeum taylorii Lewis and Bryan (Pelagophyceae), recently spreading in the Mediterranean Sea. On a rocky substratum, 18 plots 20x20 cm in size were prepared and, according to different treatments, nutrients were added in some of them to simulate eutrophication, macroalgae were removed to simulate clearings produced by grazers and mucilage was manually removed to simulate mucilage-free conditions. Differences in the composition of macroalgal assemblages were found when considering the short term effect of the considered stressors, and also the response of the most abundant taxa (DFA, ECA, Dictyotales, Laurencia spp. and Padina pavonica) varied among treatments, proving that a combined effect of such stressors on the recovery of macroalgae was present. On the contrary, the effect of treatments was neither highlighted on the most abundant algae nor on the whole structure of the macroalgal assemblage.
The cranial endocast of the Upper Devonian dipnoan Chirodipterus australis
Authors: Henderson Struan A C , Challands Tom J
Published: March 2018

One of the first endocasts of a dipnoan (lungfish) to be realised was that of the Upper Devonian taxon Chirodipterus australis. This early interpretation was based on observations of the shape of the cranial cavity alone and was not based on a natural cast or 'steinkern' nor from serial sectioning. The validity of this reconstruction is therefore questionable and continued reference to and use of this interpretation in analyses of sarcopterygian cranial evolution runs the risk of propagation of error. Here we describe a new detailed anatomical description of the endocast of Chirodipterus australis and show that it exhibits a suite of characters more typical of Lower and Middle Devonian dipnoan taxa. Notably, the small utricular recess is unexpected for a taxon of this age, whereas the ventral expansion of the telencephalon is more typical of more derived taxa. The presence of such 'primitive' characters in C. australis supports its relatively basal position as demonstrated in the most recent phylogenies of Devonian Dipnoi.

Introgressive crossbreeding between Red-Stirling and Chitralada tilapia was carried out to assess the association of STR loci polymorphisms located in the growth hormone (GH1) promoter and intron-I with growth performance. The growth of seven genetic groups was assessed using a mixed linear model. We considered sex, age, and initial weight class of each animal as fixed effects, while genetic group, STR-promoter, and STR-intron were considered as random effects. We found six alleles in the STR-promoter, which were arranged in 18 of the 21 genotypic possible combinations. Alleles 191 and 196 of the STR-promoter correspond to 80% of the assessed individuals’ total alleles, and genotypes 196/196, 191/196, and 196/201 were the most frequent. We found only three alleles in the STR-intron. The loci STR-promoter showed a significant association with the animals’ weight. Genotypes 181/181, 181/191, and 196/206 showed better average performance, and genotypes 196/201, 201/201, and 191/196 showed the worst performance. The polymorphism in the STR-intron was not associated with fish weight. The proposed approach is unprecedented for STR found in the GH1 gene. The observed association indicates that GH1 gene polymorphism could be used as a tool in tilapia breeding programs.

Honey bee colonies suffer from various pathogens, including honey bee viruses. About 24 viruses have been reported so far. However, six of them are considered to cause severe infection which inflicts heavy losses on beekeeping. The aim of this study is to detect six honey bee viruses: deformed wing virus (DWV), acute bee paralysis virus (ABPV), chronic bee paralysis virus (CBPV), sacbrood virus (SBV), kashmir bee virus (KBV), and black queen cell virus (BQCV) by a Reverse transcription polymerase chain reaction (RT-PCR). A total of 50 adult honey bee samples were obtained from apiaries situated in three different parts of the country (South, North and West Bulgaria).The results showed the highest prevalence of DWV (10/20 %), followed by SBV (6/12 %) and ABPV (2/4%), and one case of BQCV. A comparison with homology sequences available in GenBank was performed by phylogenetic analysis, and phylogenetic relationships were discussed in the context of newly described genotypes in the uninvestigated South Eastern region of Europe.In conclusion, the present study has been the first to provide sequencing data and phylogenetics analyses of some honey bee viruses in Bulgaria.
Differences in expression density and molecular weight of CR1-Like in erythrocytes of landrace swine
Authors: Zhang Jingjing , Yin Wei , Wang Chun , Jia Ruipu , Fan Kuohai , Sun Na , Sun Yaogui , Li Hongquan
Published: March 2018

Background. Porcine erythrocytes express complement receptor 1-like (CR1-like), which is involved in immune adherence.

Methods. In this study, porcine erythrocyte samples were collected from fifty-five individual Landrace swine to characterize differences in porcine CR1-like. Flow cytometry analysis was performed to examine the porcine differences in CR1-like expression density and immunoprecipitation, SDS-PAGE and Western blot were performed to detect variations in porcine CR1-like molecular weights.

Results. Different mean fluorescence intensities (MFI) of porcine erythrocytes were identified in three groups as 33.016±2.889 (40.0%), 59.974±9.299 (45.5%) and 131.241±8.375 (14.5%). Under reduced condition, three porcine CR1-like molecular weight variants were identified as 85.280±0.935 kDa (9.09%), 123.939±2.752 kDa (14.55%) and 136.696±2.028 kDa (76.36%).

Discussion. CR1-like was dispersed on the surface of porcine erythrocytes and promoted immune adherence. There have been no reports on whether differences in the expression levels and/or molecular weights of CR1-like in erythrocytes represent diversity in different individuals, and if so, whether this diversity influences the immune adherence of erythrocytes and/or whether the diversity is associated with CR1-like polymorphisms. At present, five candidate genes that are related to the differences above were found. Research examining erythrocyte immune adherence and CR1-like genes is under way. These results will provide theoretical data for future studies of the immunological mechanism of CR1-like in porcine erythrocytes.
Thermal reception in the Mexican Lance-head rattlesnake, Crotalus polystictus
Authors: Martínez Vaca-León Octavio I , Manjarrez Javier
Published: March 2018

The sensory systems of Boidae and Crotalinae snakes detect subtle differences of thermal infrared energy. The complexity of this ability involves neurophysiological mechanisms with interspecific differences in the anatomy of thermoreceptor organs and functionally in thermal detection ranges and thermal thresholds, with ecological correlations that influence the thermo-reception. However, little is known about the information these snakes obtain and use from infrared radiation. We analyzed the behavioral response of adult Mexican Lance-head Rattlesnakes (Crotalus polystictus) to static thermal stimuli, evaluating the influence of distance from the snake of the thermal stimuli, and its lizard-like or mouse-like shape. The results reveal that C. polystictus is able to detect static thermal stimuli located from 20 to 200 cm away. Head movements and tongue-flicks were the most frequently performed behaviors, which suggests they are behaviors that can facilitate the detection of subtle differences in temperature of static stimuli. In addition, we suggest that stimulus shape and temperature are important in the timing of head orientation and frequency of tongue-flicks. We discuss the possible methodological and sensory implications of this behavioral response in C. polystictus.
Analysis of Roadway Traffic Accidents Based on Rough Sets and Bayesian Networks
Authors: Xiong Xiaoxia , Chen Long , Liang Jun
Published: March 2018

The paper integrates Rough Sets (RS) and Bayesian Networks (BN) for roadway traffic accident analysis. RS reduction of attributes is first employed to generate the key set of attributes affecting accident outcomes, which are then fed into a BN structure as nodes for BN construction and accident outcome classification. Such RS-based BN framework combines the advantages of RS in knowledge reduction capability and BN in describing interrelationships among different attributes. The framework is demonstrated using the 100-car naturalistic driving data from Virginia Tech Transportation Institute to predict accident type. Comparative evaluation with the baseline BNs shows the RS-based BNs generally have a higher prediction accuracy and lower network complexity while with comparable prediction coverage and receiver operating characteristic curve area, proving that the proposed RS-based BN overall outperforms the BNs with/without traditional feature selection approaches. The proposed RS-based BN indicates the most significant attributes that affect accident types include pre-crash manoeuvre, driver’s attention from forward roadway to centre mirror, number of secondary tasks undertaken, traffic density, and relation to junction, most of which feature pre-crash driver states and driver behaviours that have not been extensively researched in literature, and could give further insight into the nature of traffic accidents.

Authors: Csiszár Csaba , Földes Dávid
Published: March 2018

Emerging info-communication and vehicle technologies (especially vehicle automation) facilitate evolvement of autonomous road freight transportation. The entire transport system and its operation undergo a major change. New service concepts are growing and the existing ones are being transformed. The changing is particularly significant in city logistics. However, there are debates about the ways of automation of processes targeting improvement of capacity utilisation and decrease of expenditures. The main research questions of the paper are therefore: what properties of the future autonomous freight transportation are presumed; what system structure is to be constructed and how the system is to be operated? After introducing the basic notions and reviews of the current systems and developments, the shifting from traditional freight transportation to autonomous system is investigated by several aspects. A system- and process-oriented analytical modelling method has been applied. The main system constituents and their connections are modelled. Finally, we elaborate the operational model of road freight transportation, which is applicable principally in metropolitan areas. In conclusion, the presentedresults appoint the research and innovation trends towards the automation of freight transportation.
The Territorial Trap and The Problem of Non-territorialized Groups
Authors: Karman Mireille Marcia
Published: March 2018

Konsep wilayah geografis atau kewilayahan fisik hampir selalu merupakan komponen utama negara yang tak terbantahkan. Dengan kewilayahan, entitas politik tersebut tidak dapat dikatakan atau didefinisikan sebagai negara. Namun demikian, pentingnya wilayah untuk sebuah negara menjadi tidak terbantahkan karena kerap dianggap remeh oleh sebagian besar ilmuwan politik modern, walaupun secara historis, konsep tersebut hanya menempati posisi penting pada abad ke-16. Tulisan ini mengikuti sejarah konsep teritorialitas (territoriality) seperti yang dijelaskan oleh Schmitt dan Kant untuk menempatkan kemunculan keterlekatan teritorial pada suatu konteks. Dengan demikian, penulis ingin menunjukkan masalah yang muncul saat teritorial diambil dari konteks tersebut dan diadopsi di dunia global yang memiliki konteks yang berbeda. Mengambil wilayah sebagai norma yang tak terbantahkan dari sebuah negara modern berkontribusi dalam menciptakan beberapa masalah laten seperti masalah identitas etnik atau agama yang perlu tunduk pada identitas nasional, ketidakmampuan untuk menangani entitas politik non-teritorial, dan ketidakmampuan untuk membayangkan cara efektif untuk mengerahkan otoritas yang efektif tanpa bergantung pada kapasitas material. Tulisan ini diakhiri dengan saran untuk membuka kembali diskusi tentang pentingnya teritorial untuk suatu negara dan apakah konsep tersebut masih dapat berfungsi sebagai asumsi keamanan dan persatuan negara.
The Philosophical Worth of Liberal Peacebuilding
Authors: Kharisma Muhammad Waffaa
Published: March 2018

Konsep peacebuilding liberal sering dikaitkan dengan kegagalan upaya liberalisasi pada negara-negara gagal yang dilanda perang, Hal ini berpangkal dari kecenderungan  praktik liberal dalam pembangunan perdamaian untuk membingkai dan memperlakukannya sebagai “proyek” liberal dan bukan sebagai upaya peacebuilding utamanya. Artikel ini melihat bahwasanya pembangunan perdamaian liberal layak dipertahankan apabila pembangunan tersebut mengakui dirinya sebagai proyek yang belum selesai. Artikel ini juga menganjurkan agar upaya pembangunan perdamaian lebih difokuskan pada solusi teknis daripada menekankannya sebagai sebuah gagasan ideologis. Peacebuilding liberal selayaknya ditarik dari definisi liberalisme yang lebih murni, terutama dengan memerhatikan gagasan kebebasan positif. Artikel ini dimulai dengan memecah premis dasar pembangunan perdamaian liberal serta menelisik dorongan ideologisnya, khususnya dengan merujuk pada paparan Roland Paris (2010). Lebih lanjut, artikel ini mengevaluasi berbagai kritik dan mengidentifikasi alternatif untuk agenda pembangunan perdamaian liberal. Selanjutnya, artikel ini menyampaikan argumen utama bahwa untuk menjauhkannya dari kritik terhadap pembangunan perdamaian liberal sebagai sebuah “proyek” idelogis, pembangunan perdamaian liberal harus mengurangi ambisi liberalnya dan meninjau lagi titik pandangnya dengan kembali mengenali bahwa liberalisme dalam tubuh gagasannya sendiri memiliki nilai-nilai yang saling bertentangan. Artikel ini kemudian menawarkan untuk memprioritaskan stabilitas di negara pascakonflik dengan berkonsentrasi pada solusi teknis kasus-per-kasus, yang seringkali dikaitkan dengan membangun kapasitas kelembagaan dan memastikan adanya landasan yang dapat menjamin masyarakat lokal menyampaikan tujuan dan kepentingan kolektifnya

Pervasive Eclogitization Due to Brittle Deformation and Rehydration of Subducted Basement: Effects on Continental Recycling?
Authors: Engi Martin , Giuntoli Francesco , Lanari Pierre , Burn Marco , Kunz Barbara , Bouvier Anne‐Sophie
Published: March 2018

The buoyancy of continental crust opposes its subduction to mantle depths, except where mineral reactions substantially increase rock density. Sluggish kinetics limit such densification, especially in dry rocks, unless deformation and hydrous fluids intervene. Here we document how hydrous fluids in the subduction channel invaded lower crustal granulites at 50–60 km depth through a dense network of probably seismically induced fractures. We combine analyses of textures and mineral composition with thermodynamic modeling to reconstruct repeated stages of interaction, with pulses of high‐pressure (HP) fluid at 650–670°C, rehydrating the initially dry rocks to micaschists. SIMS oxygen isotopic data of quartz indicate fluids of crustal composition. HP growth rims in allanite and zircon show uniform U‐Th‐Pb ages of ∼65 Ma and indicate that hydration occurred during subduction, at eclogite facies conditions. Based on this case study in the Sesia Zone (Western Italian Alps), we conclude that continental crust, and in particular deep basement fragments, during subduction can behave as substantial fluid sinks, not sources. Density modeling indicates a bifurcation in continental recycling: Chiefly mafic crust, once it is eclogitized to >60%, are prone to end up in a subduction graveyard, such as is tomographically evident beneath the Alps at ∼550 km depth. By contrast, dominantly felsic HP fragments and mafic granulites remain positively buoyant and tend be incorporated into an orogen and be exhumed with it. Felsic and intermediate lithotypes remain positively buoyant even where deformation and fluid percolation allowed them to equilibrate at HP.
Multisensor, Microseismic Observations of a Hurricane Transit Near the ALOHA Cabled Observatory
Authors: Butler Rhett , Aucan Jérome
Published: March 2018

The generation of microseisms is investigated at the ALOHA Cabled Observatory (ACO) north of Oahu during the close passage of Hurricane Lester in September 2016. Sensors include a seafloor ALOHA pressure gauge at ACO, KIP seismic data on Oahu, and nearby wave buoys. Examination of frequency‐direction spectra from wave buoys and numerical wave model outputs confirms two separate microseism generation processes: At frequencies <0.225 Hz, the microseisms are generated by swells from Hurricane Lester and Typhoon LionRock traveling in opposite directions in the vicinity of ALOHA. At higher frequencies >0.225 Hz, microseisms are dominated by waves originating from Hurricane Lester. The cross‐over frequency (0.225 Hz) occurs where the ocean wave group velocity matches the Hurricane storm track speed. Correcting for impedance, the spectrogram for energy at ALOHA closely correlates with KIP. When opposing swells meet at a distance from the Hurricane Lester and ACO, the resulting microseisms also spread geometrically in propagation to ALOHA and KIP, effectively equivalent to 1/R2. At the microseism peak, 4 September, the dominant motions of KIP are observed with retrograde particle motion characteristic of Rayleigh modes, in both the radial‐vertical and transverse‐vertical sagittal planes at distances of ≲400 km from the eye. Otherwise, the energy on the transverse component is comparable to the radial component. We hypothesize that the observed transverse energy arises locally: (1) from the extended microseism source region near ACO and (2) and from scattering by dipping structure and anisotropy embedded in the crust during emplacement at the Pacific‐Farallon ridge.
Thermal Cracking in Westerly Granite Monitored Using Direct Wave Velocity, Coda Wave Interferometry, and Acoustic Emissions
Authors: Griffiths L. , Lengliné O. , Heap M. J. , Baud P. , Schmittbuhl J.
Published: March 2018

To monitor both the permanent (thermal microcracking) and the nonpermanent (thermo‐elastic) effects of temperature on Westerly Granite, we combine acoustic emission monitoring and ultrasonic velocity measurements at ambient pressure during three heating and cooling cycles to a maximum temperature of 450°C. For the velocity measurements we use both P wave direct traveltime and coda wave interferometry techniques, the latter being more sensitive to changes in S wave velocity. During the first cycle, we observe a high acoustic emission rate and large—and mostly permanent—apparent reductions in velocity with temperature (P wave velocity is reduced by 50% of the initial value at 450°C, and 40% upon cooling). Our measurements are indicative of extensive thermal microcracking during the first cycle, predominantly during the heating phase. During the second cycle we observe further—but reduced—microcracking, and less still during the third cycle, where the apparent decrease in velocity with temperature is near reversible (at 450°C, the P wave velocity is decreased by roughly 10% of the initial velocity). Our results, relevant for thermally dynamic environments such as geothermal reservoirs, highlight the value of performing measurements of rock properties under in situ temperature conditions.

Many Numerical Weather Prediction (NWP) and climate models exhibit too warm lower tropospheres near the midlatitude continents. The warm bias has been shown to coincide with important surface radiation biases that likely play a critical role in the inception or the growth of the warm bias. This paper presents an attribution study on the net radiation biases in nine model simulations, performed in the framework of the CAUSES project (Clouds Above the United States and Errors at the Surface). Contributions from deficiencies in the surface properties, clouds, water vapor, and aerosols are quantified, using an array of radiation measurement stations near the Atmospheric Radiation Measurement Southern Great Plains site. Furthermore, an in‐depth analysis is shown to attribute the radiation errors to specific cloud regimes. The net surface shortwave radiation is overestimated in all models throughout most of the simulation period. Cloud errors are shown to contribute most to this overestimation, although nonnegligible contributions from the surface albedo exist in most models. Missing deep cloud events and/or simulating deep clouds with too weak cloud radiative effects dominate in the cloud‐related radiation errors. Some models have compensating errors between excessive occurrence of deep cloud but largely underestimating their radiative effect, while other models miss deep cloud events altogether. Surprisingly, even the latter models tend to produce too much and too frequent afternoon surface precipitation. This suggests that rather than issues with the triggering of deep convection, cloud radiative deficiencies are related to too weak convective cloud detrainment and too large precipitation efficiencies.

Three Earth System models are used to derive surface temperature responses to removal of U.S. anthropogenic SO2 emissions. Using multicentury perturbation runs with and without U.S. anthropogenic SO2 emissions, the local and remote surface temperature changes are estimated. In spite of a temperature drift in the control and large internal variability, 200 year simulations yield statistically significant regional surface temperature responses to the removal of U.S. SO2 emissions. Both local and remote surface temperature changes occur in all models, and the patterns of changes are similar between models for northern hemisphere land regions. We find a global average temperature sensitivity to U.S. SO2 emissions of 0.0055 K per Tg(SO2) per year with a range of (0.0036, 0.0078). We examine global and regional responses in SO4 burdens, aerosol optical depths (AODs), and effective radiative forcing (ERF). While changes in AOD and ERF are concentrated near the source region (United States), the temperature response is spread over the northern hemisphere with amplification of the temperature increase toward the Arctic. In all models, we find a significant response of dust concentrations, which affects the AOD but has no obvious effect on surface temperature. Temperature sensitivity to the ERF of U.S. SO2 emissions is found to differ from the models' sensitivity to radiative forcing of doubled CO2.
Hemispheric Dichotomy in Lithosphere Thickness on Mars Caused by Differences in Crustal Structure and Composition

Published: March 2018

Estimates of the Martian elastic lithosphere thickness suggest small values of ∼25 km during the Noachian for the southern hemisphere and a large present‐day difference below the two polar caps (≥300 km in the north and >110 km in the south). In addition, young lava flows suggest that Mars has been volcanically active up to the recent past. We run Monte Carlo simulations using a 1‐D parameterized thermal evolution model to investigate whether a north/south hemispheric dichotomy in crustal properties and composition can explain these constraints. Our results suggest that 55–65% of the bulk radioelement content are in the crust, and most of it (43–51%) in the southern one. The southern crust can be up to 480 kg/m3less dense than the northern one and might contain a nonnegligible proportion of felsic rocks. Our models predict a dry mantle and a wet or dry crustal rheology today. This is consistent with a mantle depleted in radioelements and volatiles. We retrieve north/south surface heat flux of 17.1–19.5 mW/m2and 24.8–26.5 mW/m2, respectively, and a large difference in lithospheric temperatures between the two hemispheres (170–304 K in the shallow mantle). This difference could leave a signature in the seismic signals measured by the future InSight mission.

This study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low‐input smallholder (<2 ha) farming systems, typical for the East African highlands. The soil cores were air dried and rewetted to water holding capacities (WHCs) of 30, 55, and 80%. Soil CO2, CH4, and N2O fluxes were measured for 48 h following rewetting. Cumulative N2O fluxes were highest from soils under perennial crops and the lowest from soils under annual crops (P < 0.001 for all WHC). At WHC of 55% or 80%, the sandy clay loam soils had lower N2O fluxes than the clay soils (P < 0.001 and P = 0.041, respectively). Cumulative soil CO2 fluxes were highest from eucalyptus plantations and lowest from annual crops across multiple WHC (P = 0.014 at 30% WHC and P < 0.001 at both 55 and 80% WHC). Methane fluxes were below detectable limits, a shortcoming for using soil cores from the top soil. This study reveals that land use and soil type have strong effects on GHG fluxes from agricultural land in the study area. Field monitoring of fluxes is needed to confirm whether these findings are consistent with what happens in situ.

High Ion‐Conducting Solid‐State Composite Electrolytes with Carbon Quantum Dot Nanofillers

Solid‐state polymer electrolytes (SPEs) with high ionic conductivity are desirable for next generation lithium‐ and sodium‐ion batteries with enhanced safety and energy density. Nanoscale fillers such as alumina, silica, and titania nanoparticles are known to improve the ionic conduction of SPEs and the conductivity enhancement is more favorable for nanofillers with a smaller size. However, aggregation of nanoscale fillers in SPEs limits particle size reduction and, in turn, hinders ionic conductivity improvement. Here, a novel poly(ethylene oxide) (PEO)‐based nanocomposite polymer electrolyte (NPE) is exploited with carbon quantum dots (CQDs) that are enriched with oxygen‐containing functional groups. Well‐dispersed, 2.0–3.0 nm diameter CQDs offer numerous Lewis acid sites that effectively increase the dissociation degree of lithium and sodium salts, adsorption of anions, and the amorphicity of the PEO matrix. Thus, the PEO/CQDs‐Li electrolyte exhibits an exceptionally high ionic conductivity of 1.39 × 10−4 S cm−1 and a high lithium transference number of 0.48. In addition, the PEO/CQDs‐Na electrolyte has ionic conductivity and sodium ion transference number values of 7.17 × 10−5 S cm−1 and 0.42, respectively. It is further showed that all solid‐state lithium/sodium rechargeable batteries assembled with PEO/CQDs NPEs display excellent rate performance and cycling stability.
How do Housing Subsidies Improve Quality of Life Among Homeless Adults? A Mediation Analysis
Authors: O'Connell Maria , Sint Kyaw , Rosenheck Robert
Published: March 2018

Supported housing, combining rent subsidies with intensive case management, is associated with improvements in quality of life of homeless adults, but factors mediating their impact on quality of life have not been studied. Twelve‐month outcome data from a randomized trial of the Housing and Urban Development‐ Veterans Affairs Supported Housing program (HUD‐VASH) showed that access to a housing rent subsidy plus intensive case management (ICM) was associated with greater improvement in subjective quality of life than ICM alone. Multiple mediation analyses were applied to identify variables that significantly mediated the relationship between receipt of housing voucher and improvements in quality of life. Significant mediating covariates were those whose 95% bias‐corrected confidence intervals, when added to the model predicting improvement in quality of life, did not overlap zero. Increases in the number of days housed, size of social network, and availability of emotional support appear to mediate improvement in quality of life and account for 71% of the benefit attributable to having a rent subsidy. Improvement in subjective quality of life though housing subsidies is mediated by gains in both material and psychosocial factors. Mediating factors deserve special attention in supported housing services.
Health Providers’ Narratives on Intimate Partner Violence Against Roma Women in Spain

Published: March 2018

This qualitative study identifies health professionals’ dominant, adaptive, and liberating narratives regarding inter‐ethnic relations when talking about intimate partner violence (IPV) and the health system responses to the way it affects Roma women. Dominant narratives are oppressive internalized stories that shape social perceptions of members of both dominant and minority groups, adaptive narratives refer to those that acknowledge asymmetry and inequality, and liberating narratives directly challenge oppression with resistant views of stereotypes and negative interpretations. A total of 25 in‐depth interviews were carried out with healthcare professionals in Spain in 2015. A discourse analysis of the interview transcriptions was conducted, showing the way in which different narratives about Roma people and IPV are combined among health providers. Dominant narratives were more salient: they were used by health providers to reflect prejudicial social perceptions in Spain that depict the Roma as a marginalized and traditional group, to construct Roma women in negative and prejudicial terms as patients, and to explain the existence of the cultural normalization of IPV among Roma women. Adaptive and liberating narratives showed a prevailing ideology in terms of the tendency to socially discriminate against Roma people. Using liberating narratives to train and raise awareness among health professionals about IPV among Roma women could facilitate a positive change in their treatment of Roma women who could be affected by IPV, helping to ameliorate the maintenance of existing prejudices.
