Authors: Marimuthu Balakrishnan , Visvalingam Balasubramanian 
Published: January 2017

Abstract
Armor grade Q&T steels very similar to AISI 4340 are used for construction of combat vehicles due to its high hardness, high strength to weight ratio and excellent toughness. The influence of friction welding parameters on microstructure and mechanical properties of such armor steel friction weld joints were evaluated. The microstructural properties of the various weld joint regions were examined by optical microscopy. It was also observed that the fully deformation zone (FDZ), the partially deformation zone (PDZ) and the heat affected zone (HAZ) have a vital effect on the tensile strength of the welded joints. Nearly 83 % of the tensile strength of the parent material (PM) can be achieved in friction welded joints. This is a 17 % higher strength than with the same parent material welded by shielded metal arc welding (SMAW) and flux cored arc welding (FCAW). The respective tensile and impact properties of the welded joints were correlated with the weld metal microstructures and fracture morphologies.
Tensile properties of continuous E-glass and basalt fiber reinforced polypropylene composites
Authors: Bekem Aylin , Dogu Mustafa , Unal Ahmet 
Published: January 2017

Abstract
Polypropylene has a higher melt viscosity and low surface tension that lead to harder interfacial bonding in composite production. However, it has some advantages like good impact strength, low water absorption, low density, low coefficient of friction and high insulating properties. In this study, E-glass fiber and basalt fiber were used to reinforce polypropylene. Powder with compatibilizer was impregnated to E-glass and basalt fiber and prepregs were produced. Then, these were embedded into polypropylene matrix and samples were obtained. Tensile properties and fiber volume ratios were determined. Also, T-peel test was applied to check bonding at the fiber-matrix interface. Fractured parts were observed and fracture types were investigated. It was concluded that both had similar bonding strength, but E-glass reinforced polypropylene composite had higher tensile properties than basalt fiber reinforced composite.
Influences of extrusion temperatures on the wear behavior of magnesium alloy AZ31 fabricated by the extrusion shear process
Authors: Hu Hongjun , Ying Yulei , Ou Zhongwen , Wang Xiaoqing 
Published: January 2017

Abstract
The wear resistance of as-cast AZ31 magnesium alloy samples fabricated by extrusion shear (ES) with various preheating temperatures (420, 400, 370 °C) of billets was tested by using pin-on-disc experiments under dry sliding wear conditions. Wear rates and friction coefficient were measured at various sliding frequencies and normal forces. To define the wear mechanism for each tested condition, the worn surfaces were analyzed using scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS). Based on the test results, the wear resistance of the ES-processed samples decreases with drop of the billet temperatures. The friction coefficients and wear rates of the samples with a preheating temperature of 370 °C are lower than those with deformation temperatures of 400 °C and 420 °C. With the increase of normal loads and reciprocating frequencies, the wear mechanism changes from mild wear (adhesion, abrasion and oxidation) to severe wear (delamination, plastic deformation and melting). Therefore, the extrusion methods have significant influences on the wear behaviors of the samples, and the wear resistance of AZ31 magnesium alloy can be improved by ES process.
ON THE ORBITAL INCLINATION OF PROXIMA CENTAURI b
Authors: Kane Stephen R. , Gelino Dawn M. , Turnbull Margaret C. 
Published: January 2017

ABSTRACT
The field of exoplanetary science has seen discovery rates increase dramatically over recent years, due largely to the data from the Kepler mission. Even so, individual discoveries of planets orbiting nearby stars are very important for studies of characterization and near-term follow-up prospects. The recent discovery of a terrestrial planet candidate orbiting Proxima Centauri presents numerous opportunities for studying a super-Earth within our own stellar backyard. One of the remaining ambiguities of the discovery is the true mass of the planet since the discovery signature was obtained via radial velocities. Here, we describe the effect of orbital inclination on the Proxima Centauri planet, in terms of mass, radius, atmosphere, and albedo. We calculate the astrometric, angular separation, and reflected light properties of the planet including the effects of orbital eccentricity. We further provide dynamical simulations that show how the presence of additional terrestrial planets within the Habitable Zone varies as a function of inclination. Finally, we discuss these effects in the context of future space-based photometry and imaging missions that could potentially detect the planetary signature and resolve the inclination and mass ambiguity of the planet.
QUASAR HOST GALAXIES AND THE MSMBH–σ* RELATION
Authors: Sheinis A. I. , López-Sánchez Á. R. 
Published: January 2017

ABSTRACT
We analyze the emission line profiles detected in deep optical spectra of quasars to derive the mass of their super-massive black holes (SMBH) following the single-epoch virial method. Our sample consists in six radio-loud (RL) quasars and four radio-quiet (RQ) quasars. We carefully fit a broad and narrow Gaussian component for each emission line in both the Hβ (10 objects) and Hα regions (5 objects). A very good agreement of the derived SMBH masses,

, is found using the fitted broad Hβ and Hα emission lines. We compare our

results with those found by previous studies. We study the relationship between the

of the quasar and the stellar velocity dispersion,

, of the host galaxy. We use the measured

and

to investigate the

–

relation for both the RL and radio-quiet subsamples. Besides the scatter, we find a good agreement between radio-quiet quasars and AGN+quiescent galaxies and between RL quasars and AGN. Our analysis does not support the hypothesis of using σ([O iii] λ5007) as a surrogate for stellar velocity dispersions in high-mass, high-luminosity quasars. We also investigate the relationship between the 5 GHz radio-continuum luminosity,

, of the quasar host galaxy with both

and

. We do not find any correlation between

and

, although we observe a trend that galaxies with larger stellar velocity dispersions have larger

. Using the results of our fitting for the narrow emission lines of [O iii] λ5007 and [N ii] λ6583 we estimate the gas-phase oxygen abundance of six quasars, being sub-solar in all cases.
VARIABLE AND POLARIZED RADIO EMISSION FROM THE T6 BROWN DWARF WISEP J112254.73+255021.5
Authors: Williams P. K. G. , Gizis J. E. , Berger E. 
Published: January 2017

ABSTRACT
Route & Wolszczan recently detected five radio bursts from the T6 dwarf WISEP J112254.73+255021.5 and used the timing of these events to propose that this object rotates with an ultra-short period of ∼17.3 minutes. We conducted follow-up observations with the Very Large Array and Gemini-North but found no evidence for this periodicity. We do, however, observe variable, highly circularly polarized radio emission. Assuming that the radio emission of this T dwarf is periodically variable on ∼hour timescales, like other radio-active ultracool dwarfs, we infer a likely period of 116 minutes. However, our observation lasted only 162 minutes and so more data are needed to test this hypothesis. The handedness of the circular polarization switches twice and there is no evidence for any unpolarized emission component, the first time such a phenomenology has been observed in radio studies of very low-mass stars and brown dwarfs. We suggest that the object’s magnetic dipole axis may be highly misaligned relative to its rotation axis.
THERMODYNAMICS AND CHARGING OF INTERSTELLAR IRON NANOPARTICLES
Authors: Hensley Brandon S. , Draine B. T. 
Published: January 2017

ABSTRACT
Interstellar iron in the form of metallic iron nanoparticles may constitute a component of the interstellar dust. We compute the stability of iron nanoparticles to sublimation in the interstellar radiation field, finding that iron clusters can persist down to a radius of ≃4.5 Å, and perhaps smaller. We employ laboratory data on small iron clusters to compute the photoelectric yields as a function of grain size and the resulting grain charge distribution in various interstellar environments, finding that iron nanoparticles can acquire negative charges, particularly in regions with high gas temperatures and ionization fractions. If ≳10% of the interstellar iron is in the form of ultrasmall iron clusters, the photoelectric heating rate from dust may be increased by up to tens of percent relative to dust models with only carbonaceous and silicate grains.
A Prospective Study to Compare Visual Outcomes Between Wavefront-optimized and Topography-guided Ablation Profiles in Contralateral Eyes With Myopia
Authors: Shetty Rohit , Shroff Rushad , Deshpande Kalyani , Gowda Roshan , Lahane Sumeet , Jayadev Chaitra 
Published: January 2017

PURPOSE:
To analyze refractive outcomes of wavefront-optimized (WFO) ablation and topography-guided custom ablation (TCAT) profiles using the Allegretto Wave excimer laser platform (Alcon Laboratories, Inc., Fort Worth, TX) in the treatment of myopia.

METHODS:
Sixty eyes of 30 patients who underwent LASIK were included in this prospective interventional study. WFO ablation was performed in one eye (WFO group) and TCAT in the fellow eye (TCAT group). The WaveLight FS200 femtosecond laser (Alcon Laboratories, Inc.) was used to create the flap and Allegretto Wave excimer laser (Alcon Laboratories, Inc.) was used for photoablation. The Pentacam HR (Oculus Optikgeräte GmbH, Wetzlar, Germany) and Allegretto Topolyzer (Alcon Laboratories, Inc.) were used to measure the corneal aberrations. Refractive visual outcomes were also compared.

RESULTS:

Accuracy, safety, and efficacy were similar in the two groups. The total root mean square (RMS) and RMS of lower order aberrations were significantly better in eyes that underwent TCAT (
P
< .05). There was a decrease in individual higher order aberrations in the TCAT group, with a statistically significant difference in the spherical aberrations (
P
= .02). The corneal asphericity (Q value) was not significantly different between the WFO (0.6 ± 0.1) and TCAT (0.51 ± 0.09) groups. The postoperative total RMS of higher order aberrations was lower in the TCAT group, but this was not statistically significant (
P
> .05). There was a more positive change in Q value and spherical aberrations in the WFO group, but this was not statistically significant.

CONCLUSIONS:
TCAT and WFO ablation provided essentially equivalent outcomes after myopic LASIK, with induction of fewer lower order aberrations and higher order aberrations following TCAT ablation.

Presbyopic Correction Using Monocular Bi-aspheric Ablation Profile (PresbyMAX) in Hyperopic Eyes: 1-Year Outcomes
Authors: Chan Tommy C.Y. , Kwok Peter S.K. , Jhanji Vishal , Woo Victor C.P. , Ng Alex L.K. 
Published: January 2017

PURPOSE:
To present the 1-year outcomes of combining monocular bi-aspheric ablation profile and contralateral monofocal LASIK in hyperopic patients with presbyopia.

METHODS:
In this retrospective case series, 36 consecutive patients (72 eyes) who underwent simultaneous bi-aspheric ablation (PresbyMAX: SCHWIND Eye-Tech-Solutions GmbH and Co KG, Kleinostheim, Germany) in the non-dominant eye and monofocal regular LASIK in the dominant eye for correction of hyperopia and presbyopia were reviewed for 1 year. Binocular uncorrected distance (UDVA), near (UNVA), corrected distance (CDVA), and distance corrected near (DCNVA) visual acuity and manifest refraction were analyzed postoperatively.

RESULTS:

At 1 year, the mean binocular UDVA improved significantly from 0.26 ± 0.25 to 0.039 ± 0.088 logMAR (
P
< .001). Binocular UNVA also improved from 0.73 ± 0.30 to 0.10 ± 0.22 logRAD (
P
< .001). Eighty-seven percent of patients achieved UDVA of 20/25 or better and 90% had UNVA of J3 or better. Simultaneous binocular distance and near vision of 20/25 and J2 or better was achieved in 70%. Only 17% of patients had a binocular DCNVA of J2 or better. No patient suffered from a loss of 2 lines of CDVA. Refractive stability was achieved for both eyes from 1 month postoperatively. The re-treatment rate was 14% for improvement of near vision within 6 months to 1 year.

CONCLUSIONS:
Presbyopic correction using monocular PresbyMAX combined with monofocal regular LASIK in the fellow eye is safe and acceptable in hyperopic patients.

Changes in Astigmatism, Densitometry, and Aberrations After SMILE for Low to High Myopic Astigmatism: A 12-Month Prospective Study
Authors: Pedersen Iben Bach , Ivarsen Anders , Hjortdal Jesper 
Published: January 2017

PURPOSE:
To evaluate 12-month changes in refraction, visual outcome, corneal densitometry, and postoperative aberrations after small incision lenticule extraction (SMILE) for myopic astigmatism.

METHODS:
This 12-month prospective clinical trial comprised 101 eyes (101 patients) treated with SMILE for myopic astigmatism with cylinder of 0.75 to 4.00 diopters (D). The preoperative, 1-week, and 1-, 3-, 6-, 9-, and 12-month examinations included measurement of manifest refraction, uncorrected distance visual acuity (UDVA), and corrected (CDVA) distance visual acuity. Astigmatic error vector analysis was performed using Al-pin's method. Densitometry and aberrations were evaluated with Pentacam HR (Oculus Optikgeräte, Wetzlar, Germany).

RESULTS:

Preoperative spherical equivalent averaged −6.78 ± 1.90 D with 1.81 ± 1.00 D in cylinder correction. After 12 months, 74% and 93% of the eyes were within ±0.50 and ±1.00 D of the attempted refraction, respectively. The logMAR UDVA and CDVA averaged 0.03 ± 0.16 and −0.08 ± 0.09, respectively. Vector analysis showed a with-the-rule undercorrection at 12 months with a mean difference vector of 0.31 D @ 91°. There was a minor counterclockwise rotation of the axis, with an arithmetic angle of error of 0.34° ± 14°. An undercorrection of approximately 11% per diopter of attempted correction was seen at 12 months. Spherical aberrations, coma, and higher order aberrations remained stable during the postoperative period (
P
< .09). After 12 months, no increase in densitometry could be identified.

CONCLUSIONS:
Treatment of astigmatism with SMILE seems to be predictable and effective, but with an astigmatic undercorrection of approximately 11% and a small counterclockwise rotation of the axis.

Change of Capsulotomy Over 1 Year in Femtosecond Laser-Assisted Cataract Surgery and Its Impact on Visual Quality
Authors: Panthier Christophe , Costantini Florent , Rigal-Sastourné Jean Claude , Brézin Antoine , Mehanna Chadi , Guedj Mikael , Monnet Dominique 
Published: January 2017

PURPOSE:
To compare the shape of the capsulotomy, its change, and its impact on visual quality over 1 year using the femtosecond laser system from the manual technique.

METHODS:
In this two-center cross-sectional study from May 2012 to June 2013, each patient had femtosecond laser-assisted cataract surgery in one eye (FLACS group) and conventional phacoemulsification cataract surgery in the other eye (CPCS group). An evaluation of the capsulotomy was performed using retroillumination slit-lamp photographs at 7 days, 6 months, and 1 year after surgery. Effective lens position (ELP), refractive error, and corrected distance visual acuity (CDVA) were analyzed.

RESULTS:

Thirty-three patients were included in the study. Diameters of capsulorhexis were more precise and deviation surfaces were lower in the FLACS group than in the CPCS group at each evaluation (
P
< .05). Femtosecond laser capsulotomies were less modified over time than manual continuous curvilinear capsulorhexis. No significant differences were observed for CDVA, refractive error, and ELP between groups.

CONCLUSIONS:
More precise capsulotomy sizing can be achieved with the femtosecond laser compared to continuous curvilinear capsulorhexis. Femtosecond laser capsulotomies are less modified over time but did not improve ELP or visual quality.

The Neonatal Window of Opportunity: Setting the Stage for Life-Long Host-Microbial Interaction and Immune Homeostasis
Authors: Torow Natalia , Hornef Mathias W. 
Published: January 2017

Abstract
The existence of a neonatal window was first highlighted by epidemiological studies that revealed the particular importance of this early time in life for the susceptibility to immune-mediated diseases in humans. Recently, the first animal studies emerged that present examples of early-life exposure–triggered persisting immune events, allowing a detailed analysis of the factors that define this particular time period. The enteric microbiota and the innate and adaptive immune system represent prime candidates that impact on the pathogenesis of immune-mediated diseases and are known to reach a lasting homeostatic equilibrium following a dynamic priming period after birth. In this review, we outline the postnatal establishment of the microbiota and maturation of the innate and adaptive immune system and discuss examples of early-life exposure–triggered immune-mediated diseases that start to shed light on the critical importance of the early postnatal period for life-long immune homeostasis.
The Influence of the Microbiome on Allergic Sensitization to Food
Authors: Plunkett Catherine H. , Nagler Cathryn R. 
Published: January 2017

Abstract
The alarming increase in the incidence and severity of food allergies has coincided with lifestyle changes in Western societies, such as dietary modifications and increased antibiotic use. These demographic shifts have profoundly altered the coevolved relationship between host and microbiota, depleting bacterial populations critical for the maintenance of mucosal homeostasis. There is increasing evidence that the dysbiosis associated with sensitization to food fails to stimulate protective tolerogenic pathways, leading to the development of the type 2 immune responses that characterize allergic disease. Defining the role of beneficial allergy-protective members of the microbiota in the regulation of tolerance to food has exciting potential for new interventions to treat dietary allergies by modulation of the microbiota.
Influence of the Gut Microbiome on Autoimmunity in the Central Nervous System
Authors: Colpitts Sara L. , Kasper Lloyd H. 
Published: January 2017

Abstract
Autoimmune disorders of the CNS have complex pathogeneses that are not well understood. In multiple sclerosis and neuromyelitis optica spectrum disorders, T cells destroy CNS tissue, resulting in severe disabilities. Mounting evidence suggests that reducing inflammation in the CNS may start with modulation of the gut microbiome. The lymphoid tissues of the gut are specialized for the induction of regulatory cells, which are directly responsible for the suppression of CNS-damaging autoreactive T cells. Whether cause or effect, the onset of dysbiosis in the gut of patients with multiple sclerosis and neuromyelitis optica provides evidence of communication along the gut–brain axis. Thus, current and future therapeutic interventions directed at microbiome modulation are of considerable appeal.
Host-Microbiota Interactions Shape Local and Systemic Inflammatory Diseases
Authors: Grigg John B. , Sonnenberg Gregory F. 
Published: January 2017

Abstract
Recent advances in understanding how the mammalian immune system and intestinal microbiota functionally interact have yielded novel insights for human health and disease. Modern technologies to quantitatively measure specific members and functional characteristics of the microbiota in the gastrointestinal tract, along with fundamental and emerging concepts in the field of immunology, have revealed numerous ways in which host-microbiota interactions proceed beneficially, neutrally, or detrimentally for mammalian hosts. It is clear that the gut microbiota has a strong influence on the shape and quality of the immune system; correspondingly, the immune system guides the composition and localization of the microbiota. In the following review, we examine the evidence that these interactions encompass homeostasis and inflammation in the intestine and, in certain cases, extraintestinal tissues. Lastly, we discuss translational therapies stemming from research on host-microbiota interactions that could be used for the treatment of chronic inflammatory diseases.
IEngage: Using Technology to Enhance Students’ Engagement in a Large Classroom

Published: January 2017

<p class="JLDAbstract">This paper aims to answer how we can increase students’ engagement in a large class. We hypothesised that the use of KeyPad, an interactive student response system, can lead to enhanced student engagement in a large classroom. We tested a model of classroom technology integration enhancing the students’ engagement among first year undergraduate students (n=131). This study provides evidence of significant effect of positive attitude and social pressure on the intent to use KeyPads. In turn, the intent to use KeyPads leads to the actual use of KeyPads which is directly associated with the level of student engagement. In addition, we find evidence for the relationship between extraversion and level of engagement such that compared to extrovert students, introvert students felt more engaged.</p>
