Parenchymatous cell division characterizes the fungal cortex of some common foliose lichens
Authors: Sanders William B. , de los Ríos Asunción 
Published: February 2017

PREMISE OF THE STUDY:Lichen‐forming fungi produce diverse vegetative tissues, some closely resembling those of plants. Yet it has been repeatedly affirmed that none is a true parenchyma, in which cellular compartments are subdivided from all adjacent neighbors by cross walls adjoining older cross walls.METHODS:Using transmission electron microscopy (TEM), we tested this assumption by examining patterns of septum formation in the parenchyma‐like cortex of three lichens of different phylogenetic affinities: Sticta canariensis, Leptogium cyanescens, and Endocarpon pusillum.KEY RESULTS:In the cortex of all three lichens, new septa adjoined perpendicularly or obliquely to previous septa. Septal walls possessed an electron‐transparent core (median) layer covered on both sides by layers of intermediate electron density. At septal junctures, the core layer of the newer septum was not continuous with that of the older septum. Amorphous, electron‐dense material often became deposited in the core region of older septal walls, and the septum gradually delaminated along its median into what could then be recognized as the distinct walls of neighboring cells. However, cells maintained continuity at pores, where adjacent remnants of the electron‐transparent core layer suggested septal partition rather than secondary establishment of a lateral wall connection via anastomosis.CONCLUSIONS:Although fungal tissues first arise by the coalescence of filaments early in lichen ontogeny, the mature cortical tissues of some lichens are comparable to true parenchyma in the unrestricted orientation of their septal cross walls and the resulting ontogenetic relationship among neighboring cell compartments.

Abstract
We present a catalog of compact sources of radio emission at 1420 MHz in the northern Galactic plane from the Canadian Galactic Plane Survey. The catalog contains 72,758 compact sources with an angular size less than 3′ within the Galactic longitude range 52° < ℓ < 192° down to a 5σ detection level of ∼1.2 mJy. Linear polarization properties are included for 12,368 sources with signals greater than 4σ

QU
in the Canadian Galactic Plane Survey (CGPS) Stokes Q and U images at the position of the total intensity peak. We compare CGPS flux densities with cataloged flux densities in the Northern VLA Sky Survey catalog for 10,897 isolated unresolved sources with CGPS flux density greater than 4 mJy to search for sources that show variable flux density on timescales of several years. We identify 146 candidate variables that exhibit high fractional variations between the two surveys. In addition, we identify 13 candidate transient sources that have CGPS flux density above 10 mJy but are not detected in the Northern VLA Sky Survey.

Abstract
We present Very Large Telescope/Spectrograph for INtegral Field Observations in the Near Infrared H- and K-band spectra of potential central stars within the inner 8″-by-8″ regions of 55 MIPSGAL “bubbles” (MBs), sub-arcminute circumstellar shells discovered in the mid-IR survey of the Galactic plane with Spitzer/MIPS. At magnitudes brighter than 15, we detect a total of 230 stars in the K band and 179 stars in the H band. We spectrally identify 145 stars in all but three MBs, with average magnitudes of 13.8 and 12.7 respectively, using spectral libraries and previous studies of near-IR stellar spectra. We also use tabulated intrinsic stellar magnitudes and colors to derive distances and extinction values, and to better constrain the classifications of the stars. We reliably identify the central sources for 21 of the 55 MBs, which we classify as follows: one Wolf–Rayet, three luminous blue variable candidates, four early-type (O to F), and 15 late-type (G to M) stars. The 21 central sources are, on average, one magnitude fainter than these in the most recent study of MBs, and we notice a significant drop in the fraction of massive star candidates. For the 34 remaining MBs in our sample, we are unable to identify the central sources due to confusion, low spectroscopic signal-to-noise ratio, and/or lack of detections in the images near the centers of the bubbles. We discuss how our findings compare with previous studies and support the trend, for the most part, between the shells’ morphologies in the mid-IR and central sources spectral types.

Abstract
We report on the analysis of the 10–1000 TeV large-scale sidereal anisotropy of Galactic cosmic rays (GCRs) with the data collected by the Tibet Air Shower Array from 1995 October to 2010 February. In this analysis, we improve the energy estimate and extend the decl. range down to −30°. We find that the anisotropy maps above 100 TeV are distinct from that at a multi-TeV band. The so-called tail-in and loss-cone features identified at low energies get less significant, and a new component appears at ∼100 TeV. The spatial distribution of the GCR intensity with an excess (7.2σ pre-trial, 5.2σ post-trial) and a deficit (−5.8σ pre-trial) are observed in the 300 TeV anisotropy map, in close agreement with IceCube’s results at 400 TeV. Combining the Tibet results in the northern sky with IceCube’s results in the southern sky, we establish a full-sky picture of the anisotropy in hundreds of TeV band. We further find that the amplitude of the first order anisotropy increases sharply above ∼100 TeV, indicating a new component of the anisotropy. All these results may shed new light on understanding the origin and propagation of GCRs.
Revised Predictions of Neutrino Fluxes from Pulsar Wind Nebulae
Authors: Palma Irene Di , Guetta Dafne , Amato Elena 
Published: February 2017

Abstract
Several pulsar wind nebulae (PWN) have been detected in the TeV band in the last decade. TeV emission is typically interpreted in a purely leptonic scenario, but this often requires that the magnetic field in the nebula be much lower than the equipartition value, as well as the assumption of an enhanced density of target radiation at IR frequencies. In this work, we consider the possibility that, in addition to the relativistic electrons and positrons, relativistic hadrons are also present in these nebulae. Assuming that some of the emitted TeV photons are of hadronic origin, we compute the associated flux of

TeV neutrinos. We use IceCube non-detection to put constraints on the fraction of TeV photons that might be contributed by hadrons and estimate the number of neutrino events that can be expected from these sources in ANTARES and KM3Net.
The Association Between Obesity and Clinical Features of Psoriatic Arthritis: A Case-control Study
Authors: Eder Lihi , Abji Fatima , Rosen Cheryl F. , Chandran Vinod , Gladman Dafna D. 
Published: February 2017

Objective.To assess whether obesity is associated with distinct psoriatic arthritis (PsA) features and whether it interacts with PsA HLA susceptibility alleles.Methods.Patients with early PsA were compared with patients with psoriasis without arthritis (PsC). The primary predictor was the body mass index (BMI) at the first visit to the clinic. The clinical features across 3 BMI groups were compared by linear trend test and Cochrane-Armitage trend test. The interaction between BMI and HLA risk alleles for psoriatic disease (HLA-B*27, B*3901, B*3801, B*0801, B*4402, B*4403, and C*0602) were assessed using logistic regression analysis.Results.There were 314 patients with early PsA, and 498 patients with PsC were analyzed. Obesity was more frequent in patients with PsA compared with PsC (OR 1.77; p = 0.002). Higher BMI was associated with older age at onset of PsA (p < 0.0001) and psoriasis (p = 0.009). The frequency of HLA-B*27 was higher in patients with normal weight compared with those with higher BMI (p = 0.002). A significant interaction was found for the combined effect of HLA-B*27 and obesity in logistic regression analysis (p = 0.036). In patients who were HLA-B*27–negative, the association between obesity and PsA was statistically significant (OR 2.39; p < 0.001), but obesity was less frequent in patients with PsA who were HLA-B*27–positive.Conclusion.Obesity is linked with late-onset psoriasis and PsA, while normal weight is associated with the presence of the HLA-B*27 allele and an earlier onset of the disease. These results highlight the differential risk factors that may drive the inflammatory process in psoriatic disease.

Objective.Despite advances integrating patient-centered outcomes into rheumatologic studies, concerns remain regarding their representativeness across diverse patient groups and how this affects equity. The Outcome Measures in Rheumatology (OMERACT) Equity Working Group aims to determine whether and how to address equity issues within the core outcome sets of domains and instruments.Methods.We surveyed current and previous OMERACT meeting attendees and members of the Campbell and Cochrane Equity Group regarding whether to address equity issues within the OMERACT Filter 2.0 Core Outcome Sets and how to assess the appropriateness of domains, instruments, and measurement properties among diverse patients. At OMERACT 2016, results of the survey and a narrative review of differential psychosocial effects of rheumatoid arthritis (i.e., on men) were presented to stimulate discussion and develop a research agenda.Results.We proposed 6 moments for which an equity lens could be added to the development, selection, or testing of patient-reported outcome measures (PROM): (1) recruitment, (2) domain selection, (3) feasibility in diverse settings, (4) instrument validity, (5) thresholds of meaning, and (6) consideration of statistical power of subgroup analyses for outcome reporting.Conclusion.There is a need to (1) conduct a systematic review to assess how equity and population characteristics have been considered in PROM development and whether these differences influence the ranking of importance of outcome domains or a patient’s response to questionnaire items, and (2) conduct the same survey described above with patients representing groups experiencing health inequities.
Water yield following forest–grass–forest transitions

Published: February 2017

Abstract. Many currently forested areas in the southern Appalachians were harvested in the early 1900s and cleared for agriculture or pasture, but have since been abandoned and reverted to forest (old-field succession). Land-use and land-cover changes such as these may have altered the timing and quantity of water yield (Q). We examined 80 years of streamflow and vegetation data in an experimental watershed that underwent forest–grass–forest conversion (i.e., old-field succession treatment). We hypothesized that changes in forest species composition and water use would largely explain long-term changes in Q. Aboveground biomass was comparable among watersheds before the treatment (208.3 Mg ha−1), and again after 45 years of forest regeneration (217.9 Mg ha−1). However, management practices in the treatment watershed altered resulting species composition compared to the reference watershed. Evapotranspiration (ET) and Q in the treatment watershed recovered to pretreatment levels after 9 years of abandonment, then Q became less (averaging 5.4 % less) and ET more (averaging 4.5 % more) than expected after the 10th year up to the present day. We demonstrate that the decline in Q and corresponding increase in ET could be explained by the shift in major forest species from predominantly Quercus and Carya before treatment to predominantly Liriodendron and Acer through old-field succession. The annual change in Q can be attributed to changes in seasonal Q. The greatest management effect on monthly Q occurred during the wettest (i.e., above median Q) growing-season months, when Q was significantly lower than expected. In the dormant season, monthly Q was higher than expected during the wettest months.

Published: February 2017

Background: Maintaining the results of orthodontic treatment and keeping the teeth in the corrected position is a great challenge in orthodontics. This study aimed to compare the survival time of three types of retainers including Hawley, 1-mm Vacuum-Formed (VF), and 1.5-mm VF within 6-month period. Methods: In this randomized clinical study, 152 patients were allocated into three groups to receive one type of the retainers. They were visited 1, 3, and 6 months after retainer delivery and checked for breakage, loss, local perforation, and discoloration from the patient's and clinician's point of view as indicators of failure. Chi-square and Fisher's exact tests were used as appropriated. Result: The results revealed that breakage was among the main reasons of failure of retainers within 6 months, which was statistically significantly different between Hawley and VF retainers, as well as between 1-mm and 1.5-mm VF retainers in the three intervals (p<0.05). Concerning the loss of retainer and discoloration from the clinician's point of view, there was no significant difference between the retainers in any interval (p>0.05). Assessing the discoloration from the patient's point of view revealed statistically significant differences between Hawley and VF retainers within the first month; however, the difference was not significant at the third and sixth months (p<0.05). The difference between the two thicknesses of VF retainer was not significant in any interval (p>0.05). By the end of the sixth month, some of the VF retainers had perforation; while, perforation was not observed in Hawley retainers.Conclusion: Considering the higher breakage rate of 1-mm VF, 1.5-mm VF seems the retainer if choice.Key words: survival time; retainer; Hawley retainer; Vacuum-formed retainer;

Published: February 2017

Background: Spinal Traumatic injuries is the major damage which is associated with morbidity and mortality rates. In this study the epidemiological characteristics of trauma, spine and their relationship to outcome were investigated. Methods: In this cross sectional study, patients’ information such as age, sex, type of injury, severity of injury, site of injury trauma who admitted to Imam Reza hospital from 29 march 2012 to 20 march 2014 were included. We used Chi-square tests to compare the types of injuries associated with the injury and regression methods. Results: The spinal trauma was identified in 105 cases, of which 9/61% were male. 1.18% of patients with incomplete injury, 5/10% 4/71% damage and no injuries were full. 6/48% of vehicle accidents, 22 cases (21%) of motorcycle accidents, 14 cases 3/13% due to the fall, the equivalent of 10 5/9% of pedestrian accidents, the equivalent of 5 7/4% injury 3 people with a knife and the rest of 9/2% were due to other causes. 6 people, equivalent to 2/9% were experiencing mortality. Type of injury, site of injury and injury severity was significantly associated with outcome. Conclusion: accidents caused by motor vehicles (cars and motorcycles) are the most common cause of trauma in spines in our country. Three factors as well as stable or unstable trauma, the severity of the initial injury and the injury as factors influencing outcome were obtained. According to the achievement of the emergency department in the early diagnosis, appropriate management such as surgery in preventing complications and improving outcome becomes more clear.Key words: Trauma; Spine;

Published: February 2017

Introduction: Wound infection is a rare complication after thyroid surgery. Because of controversy concerning with routine use of the drain by surgeons and its being considered a foreign body material, we aimed to evaluate the clinical significance and relevance of the drain tip culture and wound infection. Materials and methods: From March 2014 to March 2015, 150 consecutive patients undergoing thyroid surgery were studied. Wound infection was defined as occurring within the first 14 days from surgery. While we were suspicious to wound infection, sterile wound sampling was performed and sent to microbiology laboratory. Results: Postoperative infection developed in 4 patients (2.6%) during 2 weeks follow up. The sensitivity and specificity of the drain tip culture were 15% and 82%, respectively with a positive predictive value of 7.6%. Prolonged operative time was an independent risk factor for wound infection. There was no significant relationship between drain tip culture and wound infection. Conclusion: Routine use of the surgical drain can increase the incidence of the wound infection. However, the drain tip culture was not a predictor for wound complications after thyroid surgeries.

Relationships between radiation, clouds, and convection during DYNAMO
Authors: Ciesielski Paul E. , Johnson Richard H. , Jiang Xianan , Zhang Yunyan , Xie Shaocheng 
Published: February 2017

AbstractThe relationships between radiation, clouds, and convection on an intraseasonal time scale are examined with data taken during the Dynamics of the Madden‐Julian Oscillation (MJO) field campaign. Specifically, column‐net, as well as vertical profiles of radiative heating rates, computed over Gan Island in the central Indian Ocean (IO) are used along with an objective analysis of large‐scale fields to examine three MJO events that occurred during the 3 month period (October to December 2011) over this region. Longwave (LW) and shortwave radiative heating rates exhibit tilted structures, reflecting radiative effects associated with the prevalence of shallow cumulus during the dry, suppressed MJO phase followed by increasing deep convection leading into the active phase. As the convection builds going into the MJO active phase, there are increasingly top‐heavy anomalous radiative heating rates while the column‐net radiative cooling rate <Qr> progressively decreases. Temporal fluctuations in the cloud radiative forcing, being quite sensitive to changes in high cloudiness, are dominated by LW effects with an intraseasonal variation of ~0.4–0.6 K/d. While both the water vapor and cloud fields are inextricably linked, it appears that the tilted radiative structures are more related to water vapor effects. The intraseasonal variation of column‐net radiative heating <Qr> enhances the convective signal in the mean by ~20% with a minimum in this enhancement ~10 days prior to peak MJO rainfall and maximum ~7 days after. This suggests that as MJO convective envelope weakens over the central IO, cloud‐radiative feedbacks help maintain the mature MJO as it moves eastward.
Syntactic Ergativity
Authors: Polinsky Maria 
Published: February 2017

AbstractThis chapter presents the phenomenon of syntactic ergativity (SE), defined as the grouping of the absolutive subject and absolutive object into a natural class, to the exclusion of the ergative argument, with respect to A′‐movement. Two families of approaches to SE can be distinguished: those which place the explanatory burden on the derivation of the absolutive, and those which invoke the properties of the ergative expression to explain SE. For the first family of approaches, which include explanations based on locality and A′‐movement for case, the exclusion of the ergative from A′‐movement is a side effect of satisfying Case‐licensing needs of the absolutive. In the second type of approach, the restriction on A′‐movement of the ergative follows either from criterial freezing or from the adpositional‐phrase nature of the ergative. The approaches converge on the notion that ergative is an inherent case, assigned either by a verbal head or by an adposition selected by avhead.
Noun Incorporation
Authors: Johns Alana 
Published: February 2017

Abstract:This chapter provides an overview of noun incorporation in broad terms, examining nominals found either within or strictly adjacent to predicates from numerous languages. Syntactic issues have shifted from an earlier debate about whether noun incorporation was an operation in the lexicon or syntax to more recent discussion about whether noun incorporation is a narrow syntax or PF operation. Other issues concern whether phrases or just heads can incorporate. If phrases incorporate, are they phrasal at the point of incorporation? AGREE analyses examine the trigger for incorporation. A number of analyses posit that there is no movement of the nominal at all (pseudo noun incorporation), and utilize an adjacency relation between the verb and incorporated nominal. It remains clear that languages show similar cross‐linguistic properties in noun incorporation, even to the extent that language‐internal differences are often similar, often relating to verb class. The expansion of the set of empirical data from semantic analyses and other work continues to lead toward refinements.
