Beyond Red vs. Blue: The Political Typology - 2021
Partisan polarization remains the dominant, seemingly unalterable condition of American politics. Republicans and Democrats agree on very little – and when they do, it often is in the shared belief that they have little in common.Yet the gulf that separates Republicans and Democrats sometimes obscures the divisions and diversity of views that exist within both partisan coalitions – and the fact that many Americans do not fit easily into either one.Republicans are divided on some principles long associated with the GOP: an affinity for businesses and corporations, support for low taxes and opposition to abortion. Democrats face substantial internal differences as well – some that are long-standing, such as on the importance of religion in society, others more recent. For example, while Democrats widely share the goal of combating racial inequality in the United States, they differ on whether systemic change is required to achieve that goal.These intraparty disagreements present multiple challenges for both parties: They complicate the already difficult task of governing in a divided nation. In addition, to succeed politically, the parties must maintain the loyalty of highly politically engaged, more ideological voters, while also attracting support among less engaged voters – many of them younger – with weaker partisan ties.Pew Research Center's new political typology provides a road map to today's fractured political landscape. It segments the public into nine distinct groups, based on an analysis of their attitudes and values. The study is primarily based on a survey of 10,221 adults conducted July 8-18, 2021; it also draws from several additional interviews with these respondents conducted since January 2020
¿Anafilaxia perioperatoria? Serie de casos
Objetivos: Identificar agente causal de POH, para evitar reexposición y valorar uso de alternativa de tratamiento.
Métodos: Se describen 10 casos de POH inmediata, en todos antecedente de procedimientos quirúrgicos previos, realizándose protocolo de 3 pasos: 1°documentar registro quirúrgico para identificar exposiciones, 2° realización de pruebas cutáneas y/o epicutáneas y 3° búsqueda de alternativa de tratamiento en caso de requerir nuevo procedimiento quirúrgico y en casos seleccionados pruebas de reto.
Resultados: De un total de 10 pacientes con POH inmediata, se realizaron pruebas según el caso: bloqueadores neuromusculares, anestésicos, opioides, AINE, antibióticos, diuréticos, látex, isodine y clorhexidina; encontrando pruebas positivas en 7 pacientes (70%): en 4 (40%) bloqueadores neuromusculares, uno de ellos también positivo para látex, en 2 (20%) anestésicos y finalmente encontrando alternativa farmacológica en 2 (2%) y recomendando quirófano libre de látex en 2 casos (20%), el resto (30%) fueron catalogados como relacionados con procedimiento quirúrgico y manejo de medicamentos.
Conclusión: El estudio de las POH está enfocado en asegurar seguridad en exposiciones posteriores, por lo que además de la identificación de agente causal, el papel del alergólogo también conlleva a una búsqueda de alternativa segura en el manejo del paciente
Herschel Exploitation of Local Galaxy Andromeda (HELGA) III: The Star Formation Law in M31
We present a detailed study of how the Star Formation Rate (SFR) relates to
the interstellar medium (ISM) of M31 at ~140pc scales. The SFR is calculated
using the far-ultraviolet and 24um emission, corrected for the old stellar
population in M31. We find a global value for the SFR of 0.25+/-0.05Msun/yr and
compare this with the SFR found using the total far-infrared (FIR) luminosity.
There is general agreement in regions where young stars dominate the dust
heating. Atomic hydrogen (HI) and molecular gas (traced by carbon monoxide, CO)
or the dust mass is used to trace the total gas in the ISM. We show that the
global surface densities of SFR and gas mass place M31 amongst a set of low-SFR
galaxies in the plot of Kennicutt (1998b). The relationship between SFR and gas
surface density is tested in six radial annuli across M31, assuming a power law
relationship with index, N. The star formation law using total gas traced by HI
and CO gives a global index of N=2.03+/-0.04, with a significant variation with
radius; the highest values are observed in the 10kpc ring. We suggest that this
slope is due to HI turning molecular at ~10Msun/pc2. When looking at H2
regions, we measure a higher mean SFR suggesting a better spatial correlation
between H2 and SF. We find N~0.6 with consistent results throughout the disk -
this is at the low end of values found in previous work and argues against a
superlinear SF law on small scales.Comment: 12 pages, 10 figure

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. // Methods: We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. // Findings: We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. // Interpretation: Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.

Tunable Multiscale Nanoparticle Ordering by Polymer Crystallization
While ∼75% of commercially
utilized polymers are semicrystalline,
the generally low mechanical modulus of these materials, especially
for those possessing a glass transition temperature below room temperature,
restricts their use for structural applications. Our focus in this
paper is to address this deficiency through the controlled, multiscale
assembly of nanoparticles (NPs), in particular by leveraging the kinetics
of polymer crystallization. This process yields a multiscale NP structure
that is templated by the lamellar semicrystalline polymer morphology
and spans NPs engulfed by the growing crystals, NPs ordered into layers
in the interlamellar zone [spacing of O (10–100
nm)], and NPs assembled
into fractal objects at the interfibrillar scale, O (1–10
μm). The relative fraction
of NPs in this hierarchy is readily manipulated by the crystallization
speed. Adding NPs usually increases the Young’s modulus of
the polymer, but the effects of multiscale ordering are nearly an
order of magnitude larger than those for a state where the NPs are
not ordered, i.e., randomly dispersed in the matrix. Since the material’s
fracture toughness remains practically unaffected in this process,
this assembly strategy allows us to create high modulus materials
that retain the attractive high toughness and low density of polymers

Generalized isoperimetric inequalities for extrinsic balls in minimal submanifolds
Background
We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from studies on animals and humans where researchers use animal-attached accelerometers on moving subjects to attempt to quantify behaviour, energy expenditure and condition.
Results
The approach taken effectively concatinated three complex lines of acceleration into one visualization that highlighted patterns that were otherwise not obvious. The summation of data points within sphere facets and presentation into histograms on the sphere surface effectively dealt with data occlusion. Further frequency binning of data within facets and representation of these bins as discs on spines radiating from the sphere allowed patterns in dynamic body accelerations (DBA) associated with different postures to become obvious.
Method
We examine the extent to which novel, gravity-based spherical plots can produce revealing visualizations to incorporate the complexity of such multidimensional acceleration data using a suite of different acceleration-derived metrics with a view to highlighting patterns that are not obvious using current approaches. The basis for the visualisation involved three-dimensional plots of the smoothed acceleration values, which then occupied points on the surface of a sphere. This sphere was divided into facets and point density within each facet expressed as a histogram. Within each facet-dependent histogram, data were also grouped into frequency bins of any desirable parameters, most particularly dynamic body acceleration (DBA), which were then presented as discs on a central spine radiating from the facet. Greater radial distances from the sphere surface indicated greater DBA values while greater disc diameter indicated larger numbers of data points with that particular value.
Conclusions
We indicate how this approach links behaviour and proxies for energetics and can inform our identification and understanding of movement-related processes, highlighting subtle differences in movement and its associated energetics. This approach has ramifications that should expand to areas as disparate as disease identification, lifestyle, sports practice and wild animal ecology.Royal Society/Wolfson fund to build the Swansea University Visualization Suit
