Shear viscosity to electrical conductivity ratio in the quasiparticle models
Authors: Mykhaylova Valeriya 
Published: December 2020

AbstractWe examine the temperature dependence of the shear viscosity η to electrical conductivity σ ratio, as well as the specific shear viscosity and the scaled electrical conductivity in QCD with light and strange quarks. Our calculations are performed in kinetic theory under the relaxation time approximation combined with the quasiparticle model. We compute all transport parameters using the isotropic and transport cross sections and compare our results to a class of quasiparticle models for the QGP with Nf = 2 + 1. The results depending on different schemes are examined. The ratio (η∕s)∕(σ∕T) quantifies the relation between the relaxation times of gluons and quarks and specifies their comparative role in the evolution of the QGP. We find an excellent agreement with the (η∕s)∕(σ∕T) ratio deduced from the dynamical quasiparticle model in which the quasiparticles are characterized not only by their effective masses but also by finite widths.

Background:
Although it has long been recognized that smooth muscle Na/K ATPase modulates vascular tone and blood pressure (BP), the role of its accessory protein phospholemman has not been characterized. The aim of this study was to test the hypothesis that phospholemman phosphorylation regulates vascular tone in vitro and that this mechanism plays an important role in modulation of vascular function and BP in experimental models in vivo and in humans.

Methods:

In mouse studies, phospholemman knock-in mice (PLM
3SA
; phospholemman [FXYD1] in which the 3 phosphorylation sites on serines 63, 68, and 69 are mutated to alanines), in which phospholemman is rendered unphosphorylatable, were used to assess the role of phospholemman phosphorylation in vitro in aortic and mesenteric vessels using wire myography and membrane potential measurements. In vivo BP and regional blood flow were assessed using Doppler flow and telemetry in young (14–16 weeks) and old (57–60 weeks) wild-type and transgenic mice. In human studies, we searched human genomic databases for mutations in phospholemman in the region of the phosphorylation sites and performed analyses within 2 human data cohorts (UK Biobank and GoDARTS [Genetics of Diabetes Audit and Research in Tayside]) to assess the impact of an identified single nucleotide polymorphism on BP. This single nucleotide polymorphism was expressed in human embryonic kidney cells, and its effect on phospholemman phosphorylation was determined using Western blotting.

Results:

Phospholemman phosphorylation at Ser63 and Ser68 limited vascular constriction in response to phenylephrine. This effect was blocked by ouabain. Prevention of phospholemman phosphorylation in the PLM
3SA
mouse profoundly enhanced vascular responses to phenylephrine both in vitro and in vivo. In aging wild-type mice, phospholemman was hypophosphorylated, and this correlated with the development of aging-induced essential hypertension. In humans, we identified a nonsynonymous coding variant, single nucleotide polymorphism rs61753924, which causes the substitution R70C in phospholemman. In human embryonic kidney cells, the R70C mutation prevented phospholemman phosphorylation at Ser68. This variant’s rare allele is significantly associated with increased BP in middle-aged men.

Conclusions:
These studies demonstrate the importance of phospholemman phosphorylation in the regulation of vascular tone and BP and suggest a novel mechanism, and therapeutic target, for aging-induced essential hypertension in humans.
Afro-Asian Jurists and the Quest to Modernise the International Protection of Foreign-Owned Property, 1955–1975
Authors: Fofana Idriss Paul-Armand 
Published: December 2020

Abstract
In the two decades following the 1955 Asian African Conference in Bandung, Asian and African jurists sought to reshape international law to better incorporate the aspirations of formerly colonised peoples. The Asian-African Legal Consultative Committee (AALCC), founded one year after the Bandung Conference, helped formulate a common Afro-Asian and Third World international legal agenda by bringing together jurists and ideologically diverse Asian and African governments while collaborating with UN institutions working to codify and develop international law. The AALCC’s work and the contemporaneous writings of African and Asian jurists reveal a shared ambition to weaken the international protection of foreign-owned property by pursuing a legal agenda anchored in the structure and principles of the post-World War II international legal system. The Afro-Asian international legal agenda combined efforts to eliminate pre-war rules incompatible with the foundational principles of the UN Charter while elaborating the content of these principles through UN institutions.
Hydrocarbon Humanitarianism: Ibrahim Shihata, ‘Oil Aid’, and Resource Sovereignty
Authors: Özsu Umut 
Published: December 2020

Abstract
This article revisits Ibrahim Shihata’s role in developing the financial aid policies of the Organization of Petroleum Exporting Countries (OPEC) after the formal inauguration of the New International Economic Order project (NIEO) in 1974. As director of the OPEC Special Fund, subsequently the OPEC Fund for International Development, after its establishment in 1976, Shihata spearheaded the development of the organization’s aid policies. He also defended the NIEO as a set of sensible reform measures for redistributing wealth, resources, and technology. This article contends that Shihata’s vigorous defence of OPEC’s aid record aimed to demonstrate that the NIEO – an enterprise OPEC supported – involved not simply structural reform of the inter-state system but direct engagement with questions of intra-state distribution, and that OPEC aid was designed partly to keep the ‘Third World bloc’ from disintegrating due to the growing distance between oil-producing and non-oil-producing countries.
Evolving Best Practices: Engaging the Strengths of Both External and Local Peacebuilders in Track Two Dialogues through Local Ownership
Authors: Allen Susan H. 
Published: December 2020

Abstract
This article examines best practices in local ownership of Track Two diplomacy. Taking as a starting point the idea that best practices change over time as conflicts and social responses to them change, the article seeks out recent innovations and practices in Track Two diplomacy, focusing on practices of local ownership. A series of two reflective practice workshops with facilitators of Track Two processes offer insights on local ownership in current Track Two diplomacy. More in-depth examination of the Georgian-South Ossetian case illustrates an example of increasing local ownership developing over time during a ten year Track Two process. Together, the reflective practice workshops and the case study suggest team approaches to Track Two diplomacy so that insiders and outsiders work together as a team to facilitate, bringing the strengths of both insiders and outsiders to Track Two processes.
The Practices of ‘Splitting’ and ‘Common Accord’ Under Scrutiny: the European Parliament‘s Request for an Opinion of the European Court of Justice on the Istanbul Convention
Authors: Samoilova Elizaveta 
Published: December 2020

Abstract
With all eyes on the recent global COVID-19 pandemic, another pandemic has been growing in the shadows: violence against women. The Council of Europe’s Istanbul Convention creates a legal framework in order to protect women against all forms of violence. Its ratification process, however, has faced considerable challenges, particularly in the Central and Eastern European Member States. This article discusses the basic elements of the Istanbul Convention, reflects on the ratification process in the EU and its Member States, and sets out the main legal issues raised in the European Parliament’s request for an opinion (A-1/19 of 22 November 2019) to the Court of Justice of the European Union. Special focus is put on the choice of the correct EU legal basis and the practices of ‘splitting’ and ‘common accord’. This article argues that the European Parliament’s request for an opinion provides the perfect opportunity for the Court of Justice of the European Union to further clarify the law and the practice of concluding mixed agreements by the EU and its Member States.

Published: December 2020

Abstract
Decisions related to the production of lithic technology involve landscape-scale patterns of resource acquisition and transport that are not observable in assemblages from any one single site. In this study, we describe the stone artifacts from a discrete cluster of stone artifacts assigned to the Robberg technocomplex (22-16 ka) at the open-air locality of Uitspankraal 9 (UPK9), which is located near two major sources of toolstone in the Doring River catchment of Western Cape, South Africa. OSL dating of the underlying sediment unit provides a terminus post quem age of 27.5 ± 2.1 ka for the assemblage. Comparison of near-source artifact reduction at UPK9 with data from three rock shelter assemblages within the Doring watershed – Putslaagte 8 (PL8), Klipfonteinrand Rock Shelter (KFR), and Mertenhof Rock Shelter (MRS) – suggests that “gearing-up” with cores and blanks occurred along the river in anticipation of transport into the wider catchment area. The results reveal an integrated system of technological supply in which raw materials from different sources were acquired, reduced, and transported in different ways throughout the Doring River region.
Niyanpangu-bansu: An Important Archaeological Site for the Reconstitution of the History of Caravan Trade in Northern Benin
Authors: Mardjoua Barpougouni 
Published: December 2020

Abstract
Regarding the history of Borgu (North Benin), well-known events are the legend of Kisra, the war of Ilorin (1835-1836), and the destruction of the city named Niyanpangu. Referred to as Niyanpangu-bansu after its destruction, this archaeological site is known mostly from oral tradition and is located approximately three hundred kilometers west of Nikki (northeast Benin Republic). It has great historical significance which could contribute to our understanding of the history of caravan trade in northern Benin. This paper presents the results of the first ever archaeological research on the site in 2013 and 2014.
Transboundary Fisheries Management
Authors: Ong David M. 
Published: December 2020

Abstract
Malaysia’s unique geographical position, straddling across several seas within the Indian and Pacific Oceans, allows her to play an important role within the set of regional, sub-regional and bilateral arrangements for transboundary fisheries management in the Indo-Pacific theatre. This article first charts and then examines Malaysia’s participation within these fisheries management initiatives, beginning from the overarching international legal frameworks of unclos and the Fish Stocks Agreement, through the formal and informal regional and sub-regional fisheries management organizations, and finally, to bilateral arrangements for fisheries co-operation. Along the way, Malaysia’s policy, legal and institutional capacity, as well as her readiness to perform the role(s) required of her, in relation to regional, sub-regional, and bilateral fisheries management issues, are critically assessed.
Objective Analysis of SMOS and SMAP Sea Surface Salinity to Reduce Large-Scale and Time-Dependent Biases from Low to High Latitudes

Published: December 2020

AbstractTen years of L-band radiometric measurements have proven the capability of satellite sea surface salinity (SSS) to resolve large-scale-to-mesoscale SSS features in tropical to subtropical ocean. In mid-to-high latitudes, L-band measurements still suffer from large-scale and time-varying errors. Here, a simple method is proposed to mitigate the large-scale and time-varying errors. First, an optimal interpolation using a large correlation scale (~500 km) is used to map independently Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active Passive (SMAP) level-3 (L3) data. The mapping is compared with the equivalent mapping of in situ observations to estimate the large-scale and seasonal biases. A second mapping is performed on adjusted SSS at the scale of SMOS/SMAP spatial resolution (~45 km). This procedure merges both products and increases the signal-to-noise ratio of the absolute SSS estimates, reducing the root-mean-square difference of in situ satellite products by about 26%–32% from mid- to high latitudes, respectively, in comparison with the existing SMOS and SMAP L3 products. However, in the Arctic Ocean, some issues on satellite retrieved SSS related to, for example, radio frequency interferences, land–sea contamination, and ice–sea contamination remain challenging to reduce given the low sensitivity of L-band radiometric measurements to SSS in cold water. Using the International Thermodynamic Equation Of Seawater—2010 (TEOS-10), the resulting level-4 SSS satellite product is combined with satellite-microwave SST products to estimate sea surface density, spiciness, and haline contraction and thermal expansion coefficients. For the first time, we illustrate how useful these satellite-derived parameters are to fully characterize the surface ocean water masses at large mesoscale.
Faecal haemoglobin concentration thresholds for reassurance and urgent investigation for colorectal cancer based on a faecal immunochemical test in symptomatic patients in primary care

Published: December 2020

Background Faecal haemoglobin concentration (f-Hb), estimated using a faecal immunochemical test, can be safely implemented in primary care to assess risk of colorectal cancer (CRC). Clinical outcomes of patients presenting with symptoms of lower gastrointestinal disease were examined using an extensive range of f-Hb thresholds to decide on reassurance or referral for further investigation. Methods All patients who attended primary care and submitted a single faecal specimen faecal immunochemical test in the first year of the routine service had f-Hb estimated using HM-JACKarc: f-Hb thresholds from <2 to ≥ 400 µg Hb/g faeces (µg/g) were examined. Results Low f-Hb thresholds of <2, <7, <10 and <20 µg/g gave respective CRC risks of 0.1, 0.3, 0.3 and 0.4%, numbers needed to scope for one CRC of 871, 335, 300 and 249, and ‘false negative’ rates of 2.9, 11.4, 13.3 and 17.1%. With thresholds of <2, <7, <10 and <20 µg/g, 48.6, 74.6, 78.1 and 83.2% respectively of symptomatic patients could be managed without further investigation. With reassurance thresholds of <2 µg/g, <7 µg/g and <10 µg/g, the thresholds for referral for urgent investigation would be >400 µg/g, ≥200 µg/g and ≥100 µg/g. However, patients with a f-Hb concentration of <10 or <20 µg/g with iron deficiency anaemia, or with severe or persistent symptoms, should not be denied further investigation. Conclusions In primary care, f-Hb, in conjunction with clinical assessment, can safely and objectively determine individual risk of CRC and decide on simple reassurance or urgent, or routine referral.
Social relationship quality, depression and inflammation: A cross-cultural longitudinal study in the United States and Tokyo, Japan

Published: December 2020

Background: Depression is an illness with biological, psychological, and social underpinnings, which may include the interplay of inflammation, psychological traits, stress, social relationships, and cultural background. Aims: This work examines the prospective associations between social relationship quality and depressive symptoms, and between social relationship quality and inflammatory outcomes in two distinct cultures. Methods: Data were obtained from two longitudinal, prospective cohort studies: Midlife in the United States (MIDUS), and Midlife Development in Japan (MIDJA) between 2004 and 2010. One thousand three hundred and twenty-seven community-based adults were included in analyses, 1,054 from the United States and 273 from Tokyo, Japan. Depressive symptoms (measured by the CES-D Depression Scale) and inflammation (measured by blood sample concentrations of the inflammatory biomarkers interleukin-6 and C-reactive protein) were the outcomes. Social relationship quality was the predictor. Culture, trait independence and interdependence, and psychosocial stressors were examined as moderators of the link between social relationship quality and depressive symptoms. Results: Higher social relationship quality was associated with lower depressive symptoms in the United States (β = −6.15, p < .001), but not in Japan (β = −1.25, p = .390). Social relationship quality had no association with inflammation. Psychosocial stressors moderated the link between social relationship quality and depressive symptoms in both the United States (β = −0.39, p = .001) and Tokyo (β = −0.55, p = .001), such that social relationship quality acted as a buffer against depressive symptoms as psychosocial stress increased. Conclusion: Improving the perceived quality of social relationships appears to be a stronger target for depression interventions in the United States than in Tokyo, Japan.
Little things mean a lot: Using the biopsychosocial model for daily reports of sexual intimacy

Published: December 2020

Objectives: In the current study we used an integrated approach to late midlife sexuality. Using a biopsychosocial approach combined with spillover/crossover theory, we examined various common biological (feeling rested and physical intimacy), psychological (positive and negative mood), and social (giving and receiving support) daily processes linked with actor and partner daily physical intimacy. Methods: Data from 191 late midlife, heterosexual, White, couples (97% married, 3% cohabiting) across 14 days were used to examine our hypotheses. Participants had attended some college and about half lived in an urban area. Results: Results from dyadic logistic multilevel models suggest that even when accounting for all covariates, physical activity, positive mood, and both giving and receiving partner support were associated with an increased likelihood of daily physical intimacy. Differences in these associations were found for women compared to men. Discussion: Physical intimacy in late midlife is likely encouraged from a number of factors. Using simplistic designs may inhibit our understanding of important sexual interactions. When compared to health factors, relational factors appear to be more connected to physical intimacy. Physicians, therapists, and community educators can encourage late midlife couples to pay attention to the support they give and receive which may provide an important environment for sexual interactions.
Paul Moore's Centennial Land Run Monument
Authors: Alt Gordon 
Published: December 2020

In 2019, Sculptor Paul Moore FNSS completed his monument of the 1889 Centennial Land Run in Oklahoma City, OK. It took him over twenty years to complete this powerful work, which is one of the largest monuments in the world. It stretches over an area slightly larger than a football field and contains forty‐five powerful sculptures of horsemen and wagons racing over the Oklahoma landscape of hills and creek. It is a vision that caught the moment after a cannon announced the beginning of the Land Run, in which over 50,000 individuals took part in an effort to claim land in the Oklahoma Territory. The sculpture contains masterful images of straining horses and frantic individuals caught in a vital effort to succeed in this race to claim valuable homesteads and pastureland. Moore was awarded the Medal of Honor by the National Sculpture Society this past October, partially in regard for this outstanding public work and the quality of sculpture this extraordinarily talented artist has created in his lifetime.

Published: December 2020

Objective To compare outcome metrics of digital breast tomosynthesis (DBT) breast cancer screening with full-field digital mammogram (FFDM); specifically, to compare recall rates by the type of recalled finding, and to assess if screening with DBT versus FFDM changes biopsy recommendations and if the likelihood of malignancy varied by lesion type, if detected on DBT or FFDM screening mammogram. Methods The outcomes of 22,055 FFDM and DBT screening mammograms were retrospectively reviewed. The exams were performed at an academic institution between August 2015 and September 2016. Performance of screening with FFDM versus DBT was compared in terms of recall rate and percentage of recalled lesions resulting in a cancer diagnosis, with subset analyses performed for specific mammographic findings. Results The recall rate was 10.6% for FFDM and 8.0% for DBT ( p < 0.001). Architectural distortion was more likely to be recalled on DBT screening than FFDM ( p = 0.002), and was associated with an increased likelihood of malignancy ( p = 0.008). Asymmetries were less likely to be recalled on DBT than FFDM ( p < 0.001) screening mammogram, but more likely to be recommended for biopsy when detected on DBT. Calcifications more frequently required short-term follow-up or biopsy on both DBT and FFDM. Conclusions DBT screening confers an advantage in detection of architectural distortion representing malignancy. Recall rate of asymmetries are reduced with screening DBT, probably due to reduction of tissue superimposition. Calcifications pose a particularly difficult diagnostic challenge for breast imagers, regardless of screening mammogram type.
