“We Are Not Copyists”: Socialist Networks and Non-alignment from Below in A. Philip Randolph’s Asian Journey
Authors: Lewis Su Lin 
Published: October 2019

Abstract
In 1952, A. Philip Randolph, the head of America’s largest black union and a prominent civil rights campaigner, traveled to Japan and Burma funded by the American Committee for Cultural Freedom. In Asia, he encountered socialists and trade unionists struggling to negotiate the fractious divides between communism and capitalism within postwar states. In Burma, in particular, Western powers, the Soviet bloc, and powerful Asian neighbors used propaganda, aid missions, and subsidized travel to offer competing visions of development while accusing each other of new forms of imperialism and foreign interference. In such an environment, a battle for hearts and minds within Asian labor movements constituted the front lines of the early years of the Cold War. Randolph’s journey shows us how Asian socialists and trade unionists responded to powerful foreign interests by articulating an early sense of non-alignment, forged in part through emerging Asian socialist networks, well before this was an official strategy. The Asian actors with whom Randolph interacted in Japan and Burma mirrored his own struggles as a socialist, a trade unionist, and a “railway man” while furthering his campaign for civil rights at home. This article uses Randolph’s journey to examine parallels and divergences between African-American and Asian socialists and trade unionists during the early Cold War, an age characterized by deepening splits in the politics of the Left.

Published: October 2019

ABSTRACTGenerally, interplanetary coronal mass ejection (ICME) triggers intense and strong geomagnetic storms. It has been established that the ICME sheath-moulded planar magnetic structure enhances the amplitude of the storms. Alfvén waves embedded in ICME magnetic clouds or high solar streams including corotating interacting regions (CIRs) in turn extend the recovery phase of the storm. Here, we investigate a geomagnetic storm with a very complex temporal profile with multiple decreasing and recovery phases. We examine the role of planar magnetic structure (PMS) and Alfvén waves in the various phases of the storm. We find that fast decrease and fast recovery phases are evident during transit of PMS regions, whereas a slight decrease or recovery is found during the transit of regions embedded with Alfvénic fluctuations.

ABSTRACT
RR Lyrae stars have long been popular standard candles, but significant advances in methodology and technology have been made in recent years to increase their precision as distance indicators. We present multiwavelength (optical UBVRcIc and Gaia G, BP, RP; near-infrared JHKs; mid-infrared [3.6], [4.5]) period–luminosity–metallicity (PLZ), period–Wesenheit–metallicity (PWZ) relations, calibrated using photometry obtained from the Carnegie RR Lyrae Program and parallaxes from the Gaia second data release for 55 Galactic field RR Lyrae stars. The metallicity slope, which has long been predicted by theoretical relations, can now be measured in all passbands. The scatter in the PLZ relations is on the order of 0.2 mag, and is still dominated by uncertainties in the parallaxes. As a consistency check of our PLZ relations, we also measure the distance modulus to the globular cluster M4, the Large Magellanic Cloud and the Small Magellanic Cloud, and our results are in excellent agreement with estimates from previous studies.
On the origin of jet-like features in bow shock pulsar wind nebulae
Authors: Olmi B , Bucciantini N 
Published: October 2019

ABSTRACT
Bow shock pulsar wind nebulae are a large class of non-thermal synchrotron sources associated to old pulsars that have emerged from their parent supernova remnant and are directly interacting with the interstellar medium. Within this class a few objects show extended X-ray features, generally referred as ‘jets’, that defies all the expectations from the canonical MHD models, being strongly misaligned respect to the pulsar direction of motion. It has been suggested that these jets might originate from high energy particles that escape from the system. Here we investigate this possibility, computing particle trajectories on top of a 3D relativistic MHD model of the flow and magnetic field structure, and we show not only that beamed escape is possible, but that it can easily be asymmetric and charge separated, which as we will discuss are important aspects to explain known objects.
Three- and two-point spatial correlations of intergalactic medium at z ∼ 2 using projected quasar triplets
Authors: Maitra Soumak , Srianand Raghunathan , Petitjean Patrick , Rahmani Hadi , Gaikwad Prakash , Choudhury Tirthankar Roy , Pichon Christophe 
Published: October 2019

ABSTRACT
We present analysis of two- and three-point correlation functions of Lyα forest (at 2 ≤ z ≤ 2.5) using X-Shooter spectra of three background quasar triplets probing transverse separations of 0.5–1.6 pMpc. We present statistics based on transmitted flux and clouds identified using Voigt profile fitting. We show that the observed two-, three-point correlation functions and reduced three-point correlation (i.e. Q) are well reproduced by our simulations. We assign probabilities for realizing all the observed correlation properties simultaneously using our simulations. Our simulations suggest an increase in correlation amplitudes and Q with increasing NH i. We roughly see this trend in the observations too. We identify a concurrent gap of 17Å (i.e. 14.2 h−1 cMpc, one of the longest reported) wide along one of the triplets. Such gap is realized only in 14.2 per cent of our simulated sightlines and most of the time belongs to a void in the matter distribution. In the second triplet, we detect Damped Lyα systems (DLAs) along all three sightlines (with spatial separations 0.64 to 1.6 pMpc) within a narrow redshift interval (i.e. Δz = 0.088). Detection of a foreground quasar (∼1 pMpc from the triplet sightlines) and excess partial Lyman Limit systems (with NH i in the range $10^{16-17.2} \, \mathrm{cm}^{-2}$) around these DLAs suggest that we may be probing a large overdense region. We also report positive C iv–C iv correlations up to ∼500 km s−1 only in the longitudinal direction. Additionally, we conclude a positive C iv–Lyα correlations for higher NH i thresholds (${\gt}10^{15}\, \mathrm{cm}^{-2}$) up to a scale of ∼1000 km s−1 both in transverse and longitudinal directions.
Prediction of H α and [O iii] emission line galaxy number counts for future galaxy redshift surveys
Authors: Zhai Zhongxu , Benson Andrew , Wang Yun , Yepes Gustavo , Chuang Chia-Hsun 
Published: October 2019

ABSTRACT
We perform a simulation with Galacticus, a semi-analytical galaxy formation model, to predict the number counts of H α and [O iii] emitting galaxies. With a state-of-the-art N-body simulation, UNIT, we first calibrate Galacticus with the current observation of H α luminosity function. The resulting model coupled with a dust attenuation model, can reproduce the current observations, including the H α luminosity function from HiZELS and number density from WISP. We extrapolate the model prediction to higher redshift and the result is found to be consistent with previous investigations. We then use the same galaxy formation model to predict the number counts for [O iii] emitting galaxies. The result provides further validation of our galaxy formation model and dust model. We present number counts of H α and [O iii] emission line galaxies for three different line flux limits: 5 × 10−17erg s−1 cm−2, 1 × 10−16 erg s−1 cm−2 (6.5σ nominal depth for WFIRST GRS), and 2 × 10−16 erg s−1 cm−2 (3.5σ depth of Euclid GRS). At redshift 2 &lt; z &lt; 3, our model predicts that WFIRST can observe hundreds of [O iii] emission line galaxies per square degree with a line flux limit of 1 × 10−16 erg s−1 cm−2. This will provide accurate measurement of large-scale structure to probe dark energy over a huge cosmic volume to an unprecedented high redshift. Finally, we compare the flux ratio of H α/[O iii] within the redshift range of 0 &lt; z &lt; 3. Our results show the known trend of increasing H α/[O iii] flux ratio with H α flux at low redshift, which becomes a weaker trend at higher redshifts.
Gravitational-wave follow-up with CTA after the detection of GRBs in the TeV energy domain

Published: October 2019

ABSTRACT
The recent discovery of TeV emission from gamma-ray bursts (GRBs) by the MAGIC and H.E.S.S. Cherenkov telescopes confirmed that emission from these transients can extend to very high energies. The TeV energy domain reaches the most sensitive band of the Cherenkov Telescope Array (CTA). This newly anticipated, improved sensitivity will enhance the prospects of gravitational-wave follow-up observations by CTA to probe particle acceleration and high-energy emission from binary black hole and neutron star mergers, and stellar core-collapse events. Here we discuss the implications of TeV emission on the most promising strategies of choice for the gravitational-wave follow-up effort for CTA and Cherenkov telescopes more broadly. We find that TeV emission (i) may allow more than an hour of delay between the gravitational-wave event and the start of CTA observations; (ii) enables the use of CTA’s small size telescopes that have the largest field of view. We characterize the number of pointings needed to find a counterpart. (iii) We compute the annual follow-up time requirements and find that prioritization will be needed. (iv) Even a few telescopes could detect sufficiently nearby counterparts, raising the possibility of adding a handful of small-sized or medium-sized telescopes to the network at diverse geographic locations. (v) The continued operation of VERITAS/H.E.S.S./MAGIC would be a useful compliment to CTA’s follow-up capabilities by increasing the sky area that can be rapidly covered, especially in the United States and Australia, in which the present network of gravitational-wave detectors is more sensitive.
Structural basis for 2′-deoxyguanosine recognition by the 2′-dG-II class of riboswitches
Authors: Matyjasik Michal M , Batey Robert T 
Published: October 2019

Abstract
A recent bioinformatic analysis of well-characterized classes of riboswitches uncovered subgroups unable to bind to the regulatory molecule of the parental class. Within the guanine/adenine class, seven groups of RNAs were identified that deviate from the consensus sequence at one or more of three positions directly involved purine nucleobase recognition, one of which was validated as a second class of 2′-deoxyguanosine riboswitch (called 2′-dG-II). To understand how 2′-dG-II riboswitches recognize their cognate ligand and how they differ from a previously identified class of 2′-deoxyguanosine binding riboswitches, we have solved the crystal structure of a 2′-dG-II aptamer domain bound to 2′-deoxyguanosine. This structure reveals a global architecture similar to other members of the purine riboswitch family, but contains key differences within the ligand binding core. Defining the 2′-dG-II riboswitches is a two-nucleotide insertion in the three-way junction that promotes novel base-base interactions. Unlike 2′-dG-I riboswitches, the 2′-dG-II class only requires local changes to the ligand binding pocket of the guanine/adenine class to achieve a change in ligand preference. Notably, members of the 2′-dG-II family have variable ability to discriminate between 2′-deoxyguanosine and riboguanosine, suggesting that a subset of 2′-dG-II riboswitches may bind either molecule to regulate gene expression.
Potassium-lowering agents for the treatment of nonemergent hyperkalemia: pharmacology, dosing and comparative efficacy
Authors: Bridgeman Mary Barna , Shah Milisha , Foote Edward 
Published: October 2019

Abstract
Hyperkalemia represents a common and potentially life-threating electrolyte abnormality, a complication frequently observed in patients with heart failure, kidney disease, diabetes or in those receiving drug therapies influencing the renin–angiotensin–aldosterone system. Elevated serum potassium levels are often the result of impaired urinary potassium elimination, inadequate or reduced cellular potassium uptake, severe heart failure, use of medications influencing potassium levels in the circulation, or, more commonly, a combination of these factors. Strategies for the treatment of nonemergent hyperkalemia include the use of cation-exchange resins, polymers or other novel mechanisms of potassium trapping, including sodium polystyrene sulfonate, patiromer and sodium zirconium cyclosilicate. These agents differ in their pharmacology and mechanism of action, clinical efficacy, including onset and extent of potassium-lowering effect, dosage and administration, and potential safety and adverse effect profiles. In this review, an evaluation of these characteristics, including clinical evidence and safety concerns, in the management of nonemergent hyperkalemia will be explored.

Abstract

Introduction
We describe the development and pilot testing of the experimental tobacco and nicotine product marketplace (ETM)—a method for studying tobacco and nicotine product (TNP) choices and use behavior in a standardized way.

Aims and Methods
The ETM resembles an online store populated with TNPs. Surveillance activities and data from a US representative survey and consumer reports were used to determine the most popular TNPs for inclusion in the ETM. Standardized information and videos demonstrating how to use the TNPs were provided. To test the feasibility of using the ETM, smokers (n = 119) underwent monitoring of usual brand cigarette smoking and other TNP use (Baseline Phase) followed by access to the ETM (ETM Phase) that included their usual brand cigarettes, e-cigarettes, moist snuff, snus, and nicotine replacement therapy. During the ETM Phase, participants were provided points based on their baseline TNP consumption to exchange for TNPs in the ETM. Participants were advised to exchange points for enough TNPs to last until their next visit and to refrain from using TNPs not obtained in the ETM. A subset of the participants (n = 62) completed a survey on their experience with the ETM.

Results
The majority of the participants stated they were comfortable with navigating the ETM (97%), it was easy to determine product characteristics (89%), and they were satisfied with the products included in the marketplace (85%).

Conclusions
The ETM was well received by the vast majority of the participants and can be utilized by researchers to investigate a variety of TNP policy and regulatory science research questions.

Implications
Patterns of TNP use are complex due to greater availability, marketing, and promotion of a diverse array of TNPs. Innovative methods are needed to experimentally study TNP choices and patterns. Through describing the development of the ETM, we provide researchers with a tool that can be readily adapted to studying a variety of phenomena challenging public health.
Hilbertian Structuralism and the Frege-Hilbert Controversy†
Authors: Doherty Fiona T 
Published: October 2019

ABSTRACTThis paper reveals David Hilbert’s position in the philosophy of mathematics, circa 1900, to be a form of non-eliminative structuralism, predating his formalism. I argue that Hilbert withstands the pressing objections put to him by Frege in the course of the Frege-Hilbert controversy in virtue of this early structuralist approach. To demonstrate that this historical position deserves contemporary attention I show that Hilbertian structuralism avoids a recent wave of objections against non-eliminative structuralists to the effect that they cannot distinguish between structurally identical but importantly distinct mathematical objects, such as the complex roots of $-1$.

Authors: Cantero-Téllez Raquel , Villafañe Jorge Hugo , Valdes Kirstin , García-Orza Santiago , Bishop Mark D , Medina-Porqueres Ivan 
Published: October 2019

Abstract

Objective
To examine the effects of high-intensity laser therapy (HILT) on pain sensitivity and motor performance in patients with thumb carpometacarpal (CMC) osteoarthritis (OA).

Design
Prospective, triple-blinded, randomized, placebo-controlled trial.

Setting
Private practice, Malaga, Spain.

Subjects
Forty-three patients (mean ± SD age = 71 ± 12 years) with a diagnosis of thumb CMC OA grade 1–2 were randomized to the control group (N = 21) or experimental group (N = 22).

Methods
The experimental group (ExpG) received high-intensity laser therapy (HILT), and the control group (ConG) received a placebo treatment. The outcome measures were pain intensity (visual analog scale) and key pinch strength measurements (dynamometer). All outcome measures were collected at baseline, immediately following the intervention, at four weeks, and at 12 weeks following the intervention.

Results
Analysis of variance revealed a group × time interaction (F = 40.8, P &lt; 0.001) for pain intensity, with those patients receiving LT experiencing a greater reduction in pain compared with those receiving placebo therapy at the end of the intervention (P &lt; 0.001), as well as at 12 weeks after the intervention. Although mean values in the ExpG were higher than in the ConG for key pinch at assessment, these differences were not statistically significant.

Conclusions
HILT effectively diminishes pain intensity when used as an isolated treatment for patients with thumb CMC OA, but the effect of treatment decreases after 12 weeks.

Published: October 2019

Abstract

Objective
To confirm validity of the Self-administered Comorbidity Questionnaire modified for patients with SpA (mSCQ), and assess whether validity improves when adding items on extra-articular manifestations (EAMs), i.e. uveitis, psoriasis, and IBD, and osteoporosis and fractures.

Methods
Data from the Assessment in SpondyloArthritis international Society COMOrbidities in SPondyloArthritis study were used. Criterion validity of presence of EAMs, osteoporosis and fractures was assessed as agreement (kappa) between patients’ self-reported and physician-confirmed disease. Construct validity of the mSCQ including EAMs, osteoporosis and/or fractures (SpA-SCQ) was assessed by testing hypotheses about correlations with demographics, physical function, work ability, health utility and disease activity, and was compared with construct validity of the rheumatic disease comorbidity index.

Results
In total, 3984 patients contributed to the analyses. Agreement between patient-reported and physician-reported EAMs was substantial to almost perfect (uveitis ĸ = 0.81, IBD ĸ = 0.73, psoriasis ĸ = 0.86). Agreement for osteoporosis (ĸ = 0.38) and fractures (ĸ = 0.39) was fair. As hypothesized, the mSCQ correlated moderately to weakly with age, physical function, work limitations and health utility, and very weakly with disease activity. In contrast to our hypothesis, adding EAMs, osteoporosis and/or fractures to the mSCQ decreased correlations with several external constructs, especially among patients with peripheral SpA. Correlations with the different constructs were stronger for the both mSCQ and SpA-SCQ (rBASFI = 0.34; rEQ-5D = −0.33) compared with the rheumatic disease comorbidity index (rBASFI = 0.24; rEQ-5D = −0.21).

Conclusion
The mSCQ is a valid self-report instrument to assess the influence of comorbidities on health outcomes in patients with SpA. Adding EAMs and/or osteoporosis or fractures does not improve validity of the mSCQ.

Abstract
Neutron detection using nuclear emulsions can offer an alternative in personal dosimetry. The production of emulsions and their quality have to be well controlled with respect to their application in dosimetry. Nuclear emulsions consist mainly of gelatin and silver halide. Gelatin contains a significant amount of hydrogen, which can be used for fast neutron detection. The addition of B-10 in the emulsion is convenient for thermal neutron detection. In this paper, standard nuclear emulsions BR-2 and nuclear emulsions BR-2 enriched with boron produced at the Slavich Company, Russia, were applied for evaluation of fast and thermal neutron fluences. The results were obtained by calculation from the presumed emulsion composition without prior calibration. Evidence that nuclear emulsions used in the experiment are suitable for neutron dosimetry is provided.
Why is it difficult to understand statistical inference? Reflections on the opposing directions of construction and application of inference framework
Authors: Kula Fulya , Koçer Rüya Gökhan 
Published: October 2019

AbstractDifficulties in learning (and thus teaching) statistical inference are well reported in the literature. We argue the problem emanates not only from the way in which statistical inference is taught but also from what exactly is taught as statistical inference. What makes statistical inference difficult to understand is that it contains two logics that operate in opposite directions. There is a certain logic in the construction of the inference framework, and there is another in its application. The logic of construction commences from the population, reaches the sample through some steps and then comes back to the population by building and using the sampling distribution. The logic of application, on the other hand, starts from the sample and reaches the population by making use of the sampling distribution. The main problem in teaching statistical inference in our view is that students are taught the logic of application while the fundamental steps in the direction of construction are often overlooked. In this study, we examine and compare these two logics and argue that introductory statistical courses would benefit from using the direction of construction, which ensures that students internalize the way in which inference framework makes sense, rather than that of application.
