Published: October 2018

BackgroundThere is increasing interest in using a quantitative faecal immunochemical test (FIT) to rule out colorectal cancer (CRC) in patients with high-risk symptoms in primary care.AimThis study aimed to investigate GPs’ attitudes and willingness to use a FIT over an urgent 2-week wait (2WW) referral.Design and settingA cross-sectional online survey involving 1024 GPs working across England.MethodLogistic regression models were used to explore the likelihood of GPs using a FIT instead of a 2WW referral, and reported using odds ratios (ORs) and 95% confidence intervals (95% CIs).ResultsJust over one-third of GPs (n = 365) preferred to use a FIT as a rule-out test over a 2WW referral. GPs were more willing if they were: aged 36–45 years (OR 1.59 [95% CI = 1.04 to 2.44]); 46–55 years (OR 1.99 [95% CI = 1.14 to 3.47]); thought a FIT was highly accurate (OR 1.63 [95% CI = 1.16 to 2.29]); thought patients would benefit compared with having a colonoscopy (OR 2.02 [95% CI = 1.46 to 2.79]); and were highly confident about discussing the benefits of a FIT (OR 2.14 [95% CI = 1.46 to 3.16]). GPs were less willing if they had had >10 urgent referrals in the past year (OR 0.62 [95% CI = 0.40 to 0.94]) and thought that longer consultations would be needed (OR 0.61 [95% CI = 0.44 to 0.83]).ConclusionThe study findings suggest that the acceptability of using a FIT as a rule-out test in primary care is currently low, with less than half of GPs who perceived the test to be accurate preferring it over colonoscopy. Any potential guideline changes recommending a FIT in patients with high-risk symptoms, instead of urgent referral to rule out CRC, are likely to require intensive supporting educational outreach to increase GP confidence in the accuracy and application of a FIT in this context.

V1224 Cas: An EL CVn-type Eclipsing Binary Consisting of a Helium White Dwarf Precursor and a Delta Scuti Pulsator

Published: October 2018

Abstract
We report the discovery of a new eclipsing EL CVn-type binary, consisting of a δ Sct-type pulsator and a thermally bloated low-mass pre-He white dwarf (WD). Spectroscopy and time-series BV photometry of V1224 Cas were carried out. The spectroscopy reveals a spectral type of A3 for the star. Light curve modeling indicates that V1224 Cas is a short-period detached system containing a possible low-mass WD with an effective temperature of about 9516 K. Based on the effective temperature and the surface gravity of the A-type primary star from the spectroscopic results, the absolute parameters of the components were estimated as: M

P
= 2.16 ± 0.22M
☉, R

P
= 3.54 ± 0.12R
☉, L

P
= 55.9 ± 6.9L
☉, M

S
= 0.19 ± 0.02M
☉, R

S
= 0.97 ± 0.04R
☉, and L

S
= 6.9 ± 0.6L
☉. We therefore introduce V1224 Cas as a new EL CVn-type binary candidate. The light curves in both filters all show multi-periodic pulsations, superimposed on binary effects. We performed a preliminary frequency analysis of the light residuals after removing the synthetic eclipsing curve from the original observational data. The results suggest that the rapid light variations among the light curves could be attributed to the δ Sct-type primary component. We therefore conclude that V1224 Cas is very likely a WD+δ Sct binary.
The Three-dimensional Orbit, Orbital Parallax, and Individual Masses of the Double-lined Spectroscopic Binaries HD 183255, HD 114882, and HD 30712

Published: October 2018

Abstract
Recent speckle observations performed at the Discovery Channel Telescope, the Gemini North Telescope, and the Special Astrophysical Observatory 6 m Telescope have permitted us to calculate the visual orbit of SB2 HD 114882 for the first time and to improve the visual orbits of two other SB2 systems, HD 30712 and HD 183255, using algorithms published by the authors of this research. Recently, new high-quality spectroscopic orbits have been obtained for these binaries by other authors. We determine their 3D orbits, individual masses, and orbital parallaxes, and present them in this paper. The parallaxes are compared with those available from the Gaia mission, and a comparison between the values confirms the precision of the results obtained here.
Resonant Temperature Fluctuations in Nebulae Ionized by Short-period Binary Stars
Authors: Bautista Manuel A. , Ahmed Ehab E. 
Published: October 2018

Abstract
A prevailing open problem in planetary nebulae (PNe) research, and photoionized gaseous nebulae research at large, is the systematic discrepancies in electron temperatures and ionic abundances as derived from recombination and collisionally excited lines. Peimbert proposed the presence of “temperature fluctuations” in these nebulae, but the apparent amplitude of such fluctuations, as deduced from spectral diagnostics and/or abundance discrepancy factors (ADFs), remain unexplained by standard photoionization modeling. While this and other alternative models to explain the temperature and abundance discrepancies remain inconclusive, recent observations seem to point at a connection between nebular ADFs and a binary nature of photoionizing stars. In this paper, we show that large amplitude temperature fluctuations are expected to form in PNe photoionized by short-period binary stars. Resonant temperature fluctuations (RTFs) are first formed along the orbital disk around the binary stars, as the periodically varying ionizing radiation field induces periodic oscillations in the heating-minus-cooling function. Then, the temperature fluctuations propagate vertically to the disk as thermal waves that later steepen into radiative shocks. The binary period of the ionizing stars is determinant in the formation and propagation of temperature fluctuations, as well as in associated density fluctuations. Fluctuations propagate efficiently only in systems with binary periods significantly shorter than the gas thermalization time, of the order of 10 days. Furthermore, we propose temperature diagnostic line ratios that combine [O iii] collisionally excited lines and O ii recombination lines to determine the equilibrium temperature and the magnitude of RTFs in nebulae.

Abstract
We present a search for new members of the 300 km s−1 stream (300S) near the dwarf galaxy Segue 1 using wide-field survey data. We identify 11 previously unknown bright stream members in the APOGEE-2 and SEGUE-1 and 2 spectroscopic surveys. Based on the spatial distribution of the high-velocity stars, we confirm for the first time that this kinematic structure is associated with a 24°-long stream seen in SDSS and Pan-STARRS imaging data. The 300S stars display a metallicity range of −2.17 < [Fe/H] < −1.24, with an intrinsic dispersion of

dex. They also have chemical abundance patterns similar to those of Local Group dwarf galaxies, as well as that of the Milky Way halo. Using the open-source code galpy to model the orbit of the stream, we find that the progenitor of the stream passed perigalacticon about 70 Myr ago, with a closest approach to the Galactic center of about 4.1 kpc. Using Pan-STARRS DR1 data, we obtain an integrated stream luminosity of 4 × 103
L
⊙. We conclude that the progenitor of the stream was a dwarf galaxy that is probably similar to the satellites that were accreted to build the present-day Milky Way halo.

Published: October 2018

Abstract
V350 Sgr is a classical Cepheid suitable for mass determination. It has a hot companion which is prominent in the ultraviolet (UV) and which is not itself a binary. We have obtained two high-resolution echelle spectra of the companion at orbital velocity maximum and minimum with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope in the 1320 to 1510 Å region. By cross-correlating these spectra we obtained the orbital velocity amplitude of the companion with an uncertainty in the companion amplitude of 1.9 km s−1. This provides a mass ratio of the Cepheid to the companion of 2.1. The UV energy distribution of the companion provides the mass of the companion, yielding a Cepheid mass of 5.2 ± 0.3 M
⊙. This mass requires some combination of moderate main sequence core convective overshoot and rotation to match evolutionary tracks.

®
Excimer Laser
Authors: Reinstein Dan Z. , Carp Glenn I. , Archer Timothy J. , Day Alexander C. , Vida Ryan S. 
Published: October 2018

PURPOSE:
To report the outcomes of LASIK for mixed cylinder using the Triple-A ablation profile with the MEL 90 excimer laser (Carl Zeiss Meditec, Jena, Germany).

METHODS:
This was a retrospective analysis of all eyes treated by LASIK for mixed cylinder using the Triple-A ablation profile with the MEL 90 laser between July 2013 and October 2016. Patients were observed for 1 year after surgery. Standard outcomes analysis and vector analysis by the Alpins method were performed.

RESULTS:

The database review identified 105 eyes (82 patients) treated by LASIK for mixed cylinder using the MEL 90 laser. Mean age was 40 ± 11 years (range: 18 to 65 years). Mean attempted spherical equivalent was +0.30 ± 0.90 diopters (D) (range: −2.30 to +1.75 D). Mean cylinder was −2.93 ± 1.47 D (range: −0.75 to −7.00 D). Preoperative corrected distance visual acuity (CDVA) was 20/20 or better in 81% of eyes. Postoperative uncorrected distance visual acuity was 20/20 or better in 69% and 20/25 or better in 86% of eyes. Mean postoperative spherical equivalent relative to the intended target was −0.21 ± 0.38 D (range: −1.25 to +1.13 D), with 83% within ±0.50 D. Mean postoperative cylinder was −0.57 ± 0.41 D (range: 0.00 to −1.75 D). Geometric mean was 1.12 for the correction index and 0.25 for the index of success. For angle of error, the arithmetic mean was −0.6° ± 4.2° (range: −13.5° to 9.5°) and the absolute mean was 2.9° ± 3.0° (range: 0.0° to 13.5°). There was loss of one line of CDVA in 3% of eyes and no eyes lost two or more lines CDVA. There was a small increase in contrast sensitivity after surgery at 3, 6, 12, and 18 cycles per degree (
P
< .05).

CONCLUSIONS:
One-year outcomes of LASIK using the MEL 90 laser for mixed cylinder up to −7.00 D demonstrated excellent efficacy, safety, and predictability. Vector analysis found a 12% overcorrection in magnitude of refractive cylinder. Given the high accuracy for angle of error, a nomogram could be applied to reduce the over-correction and further improve the uncorrected distance visual acuity outcomes.

“Our delight is for the amir of the English”: a Bornoan history of the First World War (North-Eastern Nigeria)
Authors: Dewière Rémi , Hiribarren Vincent 
Published: October 2018

On 18 November 1914, Abubakar Garbai, the Shehu of Borno, sent a letter to Frederick Lugard, the Governor General of Nigeria, announcing that the Bornoans would fight alongside the British despite the fact that they were fighting against the Ottomans. This article uses the letter sent by Shehu Garbai to analyse the global, trans-Saharan and trans-Sahelian layers of conflicts in the Lake Chad region at the beginning of the First World War. This document is a perfect illustration of the pragmatic alliance formed by the British colonial officers and the elite of Borno (Nigeria) to defeat the German troops in Northern Cameroon. This article concludes that it is impossible to write the history of the First World War in central Africa without understanding the long term and localised conflicts in the Lake Chad area.
Why did the Italians go to Libya?
Authors: Ungari Andrea 
Published: October 2018

This article explores the motivations behind the Italian occupation of Tripolitania and Cyrenaica in 1911-1912, a conflict which, some scholars claim, ignited a chain of events that eventually led to the outbreak of the war in Europe at the end of July 1914. It illustrates the attitude of the political forces in Italy but also the international context in which the war was decided and took place, and it confronts the question of whether, from a military point of view, the war was modern or not.
The Italian community of Tunisia: From Libyan Colonial Ambitions to the First World War
Authors: Montalbano Gabriele 
Published: October 2018

This paper analyses how the Italian settlers in the French protectorate of Tunisia reacted to the Libyan war and to WWI. The case of this Italian community between 1911 and 1915 is particularly interesting regarding its position in terms of migration, nation-building, and colonialism. Between the end of the 19th century and the beginning of 20th century, the Kingdom of Italy experienced mass migration of its workers to foreign countries and, at the same time, it aspired to colonial expansion in Africa. Nationalists wanted to make Italian migrants a tool for national imperialism. According to them, the large number of Italians living in foreign colonial possessions, as in the case of French Maghreb, justified colonialist claims towards Libya. Italian migrants were mobilised by homeland institutions and by the nationalist upper-class in order to take part in a wider national project that involved expatriate communities. The Libyan war and the Great War exacerbated social tensions in the Tunisian society and affected the living conditions of the Italians. Living under French colonial rule, some Italian settlers considered the Libyan conquest as an opportunity for social improvement of their migrant working-class status. After the declaration of war of Italy in 1915, the community was directly involved in the war effort, sending soldiers and money to the motherland. A kind of welfare system was created in order to provide aid to the poorest members of the community, strengthening the migrants’ nationalist feeling. Ultimately, this paper emphasises the community-building function of the war effort, highlighting how social classes and colonial dynamics are intertwined in the Italian nation-building process in Tunisia.
RNA Splicing in the Transition from B Cells to Antibody-Secreting Cells: The Influences of ELL2, Small Nuclear RNA, and Endoplasmic Reticulum Stress
Authors: Nelson Ashley M. , Carew Nolan T. , Smith Sage M. , Milcarek Christine 
Published: October 2018

Abstract
In the transition from B cells to Ab-secreting cells (ASCs) many genes are induced, such as ELL2, Irf4, Prdm1, Xbp1, whereas other mRNAs do not change in abundance. Nonetheless, using splicing array technology and mouse splenic B cells plus or minus LPS, we found that induced and “uninduced” genes can show large differences in splicing patterns between the cell stages, which could influence ASC development. We found that ∼55% of these splicing changes depend on ELL2, a transcription elongation factor that influences expression levels and splicing patterns of ASC signature genes, genes in the cell-cycle and N-glycan biosynthesis and processing pathways, and the secretory versus membrane forms of the IgH mRNA. Some of these changes occur when ELL2 binds directly to the genes encoding those mRNAs, whereas some of the changes are indirect. To attempt to account for the changes that occur in RNA splicing before or without ELL2 induction, we examined the amount of the small nuclear RNA molecules and found that they were significantly decreased within 18 h of LPS stimulation and stayed low until 72 h. Correlating with this, at 18 h after LPS, endoplasmic reticulum stress and Ire1 phosphorylation are induced. Inhibiting the regulated Ire1-dependent mRNA decay with 4u8C correlates with the reduction in small nuclear RNA and changes in the normal splicing patterns at 18 h. Thus, we conclude that the RNA splicing patterns in ASCs are shaped early by endoplasmic reticulum stress and Ire1 phosphorylation and later by ELL2 induction.
OMAN AND IBADISM FROM A RELIGIOUS REGIONAL PERSPECTIVE
Authors: Al-Salimi Abdulrahman 
Published: October 2018

Questo paper affronta il tema dellâ€™identitÃ Omanita e lâ€™ideologico religioso Islamico Ibadita. Fra gli elementi principali che caratterizzano lâ€™Oman, si possono considerare: 1. La sua particolare configurazione geografica. 2. La sua popolazione multi-culturale e multi-religiosa sin da epoche antichissime e precedent lâ€™Islam stesso. 3. La dottrina Islamica Ibadita. Conseguentemente, in primo luogo lâ€™Autore si sofferma sulle particolari connotazioni geografiche dellâ€™Oman e suoi molteplici â€˜paesaggiâ€™, i quali hanno indubbiamnete avuto un profondo impatto sugli habitat umani e la loro organizzazione allâ€™interno delle diverse nicchie ecologiche del Paese, risalendo a secoli se non a millenni or sono. Riguardo a questâ€™ultimo aspetto, una delle principali connotazioni Ã¨ stata quella del tribalismo e le sue complementarietÃ allâ€™interno di una cornice che, in Oman, Ã¨ sempre stata caratterizzata da multi-culturalitÃ e multi-religiositÃ . Quindi, con lâ€™avvento dellâ€™Islam, un nuovo fattore si Ã¨ imposto sulla scena storica omanita: lâ€™Ibadismo e le sue dinamiche. Dopo un breve schema storico e in ampia parte riferendosi al paper precedente, il discorso puntualizza i principÃ® base dellâ€™Ibadismo e della sua evoluzione nel tempo, il ruolo giocato in Oman nel corso dei secoli, il suo impatto sulla societÃ locale e il modello politico-istituzionale che esso ha contribuito a forgiare e modellare. Si tratta di una ereditÃ culturale tramandata nei secoli fino ad oggi. Infine, lâ€™Autore dÃ un rapido ma chiaro affresco dellâ€™Ibadismo e del suo ideologico religioso oggi, il rapporto fra questa ideologia religiosa e il concetto di ModernitÃ tecnologica e sociale, Corano e principÃ® guida religiosi di fronte alle diversitÃ , la risposta Ibadita di fronte a un nuovo modello di societÃ inter-religiosa e inter-etnica.
