Planetesimal Population Synthesis: Pebble Flux-regulated Planetesimal Formation
Authors: Lenz Christian T. , Klahr Hubert , Birnstiel Tilman 
Published: March 2019

Abstract
We propose an expression for a local planetesimal formation rate proportional to the instantaneous radial pebble flux. The result—a radial planetesimal distribution—can be used as an initial condition to study the formation of planetary embryos. We follow the idea that one needs particle traps to locally enhance the dust-to-gas ratios sufficiently, such that particle gas interactions can no longer prevent planetesimal formation on small scales. The locations of these traps can emerge everywhere in the disk. Their occurrence and lifetime is subject to ongoing research; thus, here they are implemented via free parameters. This enables us to study the influence of the disk properties on the formation of planetesimals, predicting their time-dependent formation rates and the location of primary pebble accretion. We show that large α-values of 0.01 (strong turbulence) prevent the formation of planetesimals in the inner part of the disk, arguing for lower values of around 0.001 (moderate turbulence), at which planetesimals form quickly at all places where they are needed for proto-planets. Planetesimals form as soon as dust has grown to pebbles (mm to dm) and the pebble flux reaches a critical value, which is after a few thousand years at 2–3 au and after a few hundred thousand years at 20–30 au. Planetesimal formation lasts until the pebble supply has decreased below a critical value. The final spatial planetesimal distribution is steeper compared to the initial dust and gas distribution, which helps explain the discrepancy between the minimum mass solar nebula and viscous accretion disks.
Deriving Galaxy Cluster Velocity Anisotropy Profiles from a Joint Analysis of Dynamical and Weak Lensing Data
Authors: Stark Alejo , Miller Christopher J. , Halenka Vitali 
Published: March 2019

Abstract
We present an analytic approach to lift the mass-anisotropy degeneracy in clusters of galaxies by utilizing the line-of-sight velocity dispersion of clustered galaxies jointly with weak lensing inferred masses. More specifically, we solve the spherical Jeans equation by assuming a simple relation between the line-of-sight velocity dispersion and the radial velocity dispersion and recast the Jeans equation as a Bernoulli differential equation that has a well-known analytic solution. We first test our method in cosmological N-body simulations and then derive the anisotropy profiles for 35 archival data galaxy clusters with an average redshift of

. The resulting profiles yield a weighted average global value of

(stat) ±0.15 (sys). This indicates that clustered galaxies tend to globally fall on radially anisotropic orbits. We note that this is the first attempt to derive velocity anisotropy profiles for a cluster sample of this size utilizing joint dynamical and weak lensing data.
Think Global, Act Local: The Influence of Environment Age and Host Mass on Type Ia Supernova Light Curves
Authors: Rose B. M. , Garnavich P. M. , Berg M. A. 
Published: March 2019

Abstract
The reliability of Type Ia Supernovae (SNe Ia) may be limited by the imprint of their galactic origins. To investigate the connection between supernovae and their host characteristics, we developed an improved method to estimate the stellar population age of the host as well as the local environment around the site of the supernova. We use a Bayesian method to estimate the star formation history and mass weighted age of a supernova’s environment by matching observed spectral energy distributions to a synthesized stellar population. Applying this age estimator to both the photometrically and spectroscopically classified Sloan Digital Sky Survey II supernovae (N = 103), we find a 0.114 ± 0.039 mag “step” in the average Hubble residual at a stellar age of ∼8 Gyr; it is nearly twice the size of the currently popular mass step. We then apply a principal component analysis on the SALT2 parameters, host stellar mass, and local environment age. We find that a new parameter, PC1, consisting of a linear combination of stretch, host stellar mass, and local age, shows a very significant (4.7σ) correlation with Hubble residuals. There is a much broader range of PC1 values found in the Hubble flow sample when compared with the Cepheid calibration galaxies. These samples have mildly statistically different average PC1 values, at ∼2.5σ, resulting in at most a 1.3% reduction in the evaluation of H
0. Despite accounting for the highly significant trend in SN Ia Hubble residuals, there remains a 9% discrepancy between the most recent precision estimates of H
0 using SN Ia and the CMB.
Search for Gravitational Lensing Signatures in LIGO-Virgo Binary Black Hole Events
Authors: Hannuksela O. A. , Haris K. , Ng K. K. Y. , Kumar S. , Mehta A. K. , Keitel D. , Li T. G. F. , Ajith P. 
Published: March 2019

Abstract
We search for signatures of gravitational lensing in the binary black hole events detected by Advanced LIGO and Virgo during their first two observational runs. In particular, we look for three effects: (1) evidence of lensing magnification in the individual signals due to galaxy lenses, (2) evidence of multiple images due to strong lensing by galaxies, and (3) evidence of wave optics effects due to point-mass lens. We find no compelling evidence of any of these signatures in the observed gravitational wave signals. However, as the sensitivities of gravitational wave detectors improve in the future, detecting lensed events may become quite likely.
Investigation of the small break conditions in the primary circuit of a VVER-1000 reactor*
Authors: Belozerov Vladimir I. , Zhuk Mikhail M. , Terekhova Anna M. 
Published: March 2019

Modes with violation of the reactor plant cooling conditions on the primary circuit side of a VVER reactor were simulated using the TRAC-PD2 and Open FOAM thermohydraulic codes (TRAC-PD2 1981, OpenFOAM User Guide Version 1.6. 2009, OpenFOAM Programmer’s Guide Version 1.6. 2009) based on energy and mass conservation equations for the three-dimensional unsteady flow of a two-phase mixture. Coupled simulation of the dynamics of neutronic and thermohydraulic processes (TRAC-PD2 1981, OpenFOAM User Guide Version 1.6. 2009, OpenFOAM Programmer’s Guide Version 1.6. 2009, Bolshagin et al. 2009, Galanin 1971, Weinberg and Wigner 1961, Ovchinnikov and Semenov 1988, Report LA-UR-03-1987) aims to improve the qualitative understanding and the quantitative presentation of their effects on safety.
Investigating these modes using the above thermohydraulic codes makes it possible to analyze the course of transients and certain emergency processes without using the industrial testing method, this providing the basis for solving the problems of ensuring the reliability, operational safety and efficiency of nuclear power plants.
A modern nuclear reactor is a complex system studying and calculating which requires more than the use of simple theoretical models. Thermohydraulic calculations are an essential part of most engineering and technological development works in nuclear power. Since, in conditions of an NPP, no technologically conventional way can be used to verify and update the results and findings of an a priori analysis on the basis of commercial tests, investigations based on codes are used in some cases as the tools to study and predict the parameters of thermohydraulic processes in the reactor’s circulation circuit.
The main purpose of the study is to calculate and investigate, based on codes, modes with violation of the reactor plant cooling conditions on the primary circuit side of a VVER reactor in order to determine if calculated parameters conform to the acceptance criteria established by regulatory documents.
Benefits of COMMUNITY MEETINGS in the Corporate Setting After the Suicide of a Coworker
Authors: Clements Paul T , DeRanieri Joseph T , Fay-Hillier Theresa M , Henry Gloria C 
Published: March 2019

ABSTRACT
When an employee commits suicide, his or her coworkers are confronted unexpectedly with issues related to the sudden traumatic death. Being inundated with questions, grappling with acceptance of the loss, and exploring how this could have happened are factors that can complicate the bereavement process and delay a return to workplace homeostasis. Understanding the dynamics and issues related to grief and bereavement after sudden traumatic death potentially can accelerate the recovery process and promote restoration of workforce normalcy for employees and organizations. This can be significantly important to corporate managers and administrators who must maintain ongoing productivity despite such disruption, while promoting adaptive coping for their employees.
Early Detection of Radiation Retinopathy in Pediatric Patients Undergoing External Beam Radiation Using Optical Coherence Tomography Angiography
Authors: Adeniran Janelle Fassbender , Sophie Raafay , Adhi Mehreen , Ramasubramanian Aparna 
Published: March 2019

BACKGROUND AND OBJECTIVE:
Detection of early vascular changes observed on optical coherence tomography angiography (OCTA) in children who have received external beam radiation and are at risk of developing radiation retinopathy (RR).

PATIENTS AND METHODS:
Eleven pediatric patients (20 eyes) with history of irradiation and nine healthy subjects (14 eyes) were retrospectively studied after dilated fundus exam and imaging.

RESULTS:

Four eyes of three patients had clinical RR. Eyes with radiation exposure but no RR had worse vision (no RR: logMAR 0.09 ± 0.14, Snellen 20/25) than controls (logMAR 0.01 ± 0.03, Snellen 20/21;
P
= .04) and increased superficial foveal avascular zone (FAZ) area (radiation: 0.31 ± 0.15 vs. control: 0.18 ± 0.10;
P
= .005). Eyes with RR had worse vision (RR: logMAR 0.34 ± 0.31, Snellen 20/44) than eyes with no RR (
P
= .001) and had increased deep FAZ (RR: 1.23 ± 0.40 vs. no RR: 0.68 ± 0.25;
P
= .01), but similar superficial FAZ (RR: 0.44 ± 0.28 vs. no RR: 0.31 ± 0.15;
P
= .42).

CONCLUSIONS:
Eyes with mildly decreased vision but no RR show superficial but not deep plexus changes. Eyes with RR have both superficial and deep plexus changes.

Modified Cow-Hitch Suture for Repositioning of Subluxated Scleral-Fixated Rigid Intraocular Lens
Authors: Ma I-Hsin , Tsai Chia-Ying , Yang Chung-May , Lai Tso-Ting 
Published: March 2019

BACKGROUND AND OBJECTIVE:
To describe a new technique for repositioning a subluxated scleral-fixated rigid intraocular lens (IOL).

PATIENTS AND METHODS:
The authors present a modified intraocular threading technique to tie a cow-hitch knot around the eyelet on the dislocated haptic of a scleral-fixated rigid IOL. This technique uses three small corneal incisions to eliminate the need for IOL externalization and minimized the size and number of wounds.

RESULTS:
Three consecutive cases of subluxated haptics in two patients underwent this procedure. Postoperative IOL centration and alignment were satisfactory without tilt. No surgical-related complication was observed 1 year after surgery.

CONCLUSION:
A rigid IOL could be repositioned to a desired axis and centration via this modified cow-hitch technique, with better IOL support as compared with a single tie.

Authors: Tan Chor Lip Henry , Jih Huei Tan , Chong Abdullah Ariz , Rahman Noor Azman Bin 
Published: March 2019

AbstractThe incidence of neurenteric cyst (NC) is rare, accounting for 0.3%–1.3% of all spine tumors. The occurrence of quadriplegia caused by NC is even scarcer. Herein we report on a young girl with a rare NC over the C2-C5 spinal cord, which led to the morbidity of permanent quadriplegia despite early surgical intervention. This case highlights the rare morbidity of cervical cord NC presenting with permanent quadriplegia that failed to respond despite early surgical excision.

Published: March 2019

Abstract
Objective: To report our single-center experience in terms of patient clinical characteristics, treatment outcomes, and chemotherapy-related toxicities in patients with low-risk gestational trophoblastic neoplasia (GTN). Materials and Methods: A retrospective cross-sectional study (2008–2013) was conducted at a tertiary health-care hospital in Saudi Arabia. Forty-four (n = 44) patients met the inclusion criteria for low-risk GTN. Methotrexate (MTX) was administered in a 5-day regimen: 0.3–0.5mg/kg intravenously (IV) daily for 5 days every 2 weeks (maximum 25mg per dose). Actinomycin D (ActD) was administered 1.25mg/m2 pulsed IV every 2 weeks. Results: The majority of patients had molar pregnancy as the antecedent event (86%), developed GTN within the first 4 months after the initial evacuation (93.2%), had human chorionic gonadotropin levels between 1,000 and 10,000 mIU/dL (36.3%), and had the World Health Organization prognostic scores from 0 to 2 (48.7%). Only 38 patients accepted treatment with chemotherapy. A total of 37 patients received first-line MTX; 34 patients of them achieved complete remission (CR, 92%). The three patients who developed MTX resistance were salvaged with sequential ActD and all achieved CR of 100%. Only one patient received first-line ActD and achieved CR. The overall survival as well as cure rate for all patients with low-risk GTN was 100%. No patient developed MTX-related hepatic toxicity or ActD-related blister formation. No severe adverse effects occurred. Conclusion: Our 5-day IV MTX regimen was highly effective in treating patients with low-risk GTN, with CR rate of 92% and no severe toxicity. Primary and sequential ActD therapy appears to be very effective.

IntroductionRecently introduced microUSB ultrasound probe, which can be connected to personal mobile device constitutes a new class of diagnostic pocket size imaging devices (PSID).The aim of this study was to assess the feasibility and clinical utility of real-time tele-echocardiography with the use such device.Material and methodsThe study group comprised 30 patients (18 men and 12 women; mean age: 54 ±14 years; mean BMI: 27 ±6 kg/m2), admitted to various hospital departments (infectious diseases, internal medicine and cardiology). All patients underwent focused echocardiographic examination performed by an inexperienced operator using PSID and collaborating remotely in real-time with cardiologist by means of tele-consultation. Before commencing the examination, the operators underwent one hour training in use of the PSID.ResultsIn most of patients PSID imaging provided sufficient diagnostic image quality. The dimensions of left ventricle, left atrium and the aorta obtained during the this examination showed good correlation with standard echocardiography (r = 0.89, r = 0.82, r = 0.92 respectively), but the correlation for TAPSE measurements was less pronounced (r = 0.52). The agreement in detection of pathologies (wall motion abnormalities, morphological and functional valvular abnormalities) between the tele-echocardiography and standard echocardiographic examination was good to very good ( ranged from 0.648 to 0.823).ConclusionsPocket size imaging devices allows an inexperienced operator to perform a focused echocardiographic examination under a remote supervision of an experienced cardiologist. The introduction of new technology in the form of PSID with tele-echocardiography feature can revolutionize access to this imaging technique.

Published: March 2019

IntroductionAmerican football is a high-impact collision sport, which may lead to high injury rates in the players. Thus, knowing the aetiology and incidence of injuries may be useful not only for the treatment, but especially to help sports professionals to develop strategies or mechanisms of prevention while aiming to maintain the physical integrity of the athletes.PurposeThe aim of the study was to verify the prevalence of injury among American football players from the Santa Catarina state of Brazil.MethodsThe total of 140 athletes were evaluated in the study with the use of an online questionnaire. Descriptive logistic regression and t-test analysis were applied (<i>p</i> < 0.05).ResultsA high injury prevalence (74%) in the evaluated athletes was observed. Most of these injuries occurred during training (56%) and by direct contact between players (64%). Shoulders, knees, and hand/fingers were the most commonly injured body parts (14%, 13%, 12%, respectively). The most frequent types of injuries were those related to joints (46%) and
muscles (39%), and very few concussions were reported. We found a significant positive association showing that the athletes that performed a conditioning program presented higher injury prevalence (<i>p</i> = 0.01).

PurposeThe present study aimed to compare the acute hormonal and metabolic response following a resistance training (RT) session with and without inter-set stretching.MethodsOverall, 13 men with minimum 1 year of experience with RT were randomly allocated to 2 groups: traditional RT group (TRT; <i>n</i> = 6; age: 22.5 ± 4.7 years; body weight: 83.1 kg ± 5.7 kg; height: 179.8 ± 6.9 cm; BMI: 25.73 ± 1.17 kg/m2) and stretching RT group (SRT; <i>n</i> = 7; age: 23.4 ± 4.3 years; body weight: 82.3 ± 11.7 kg; height: 177.7 ± 11.0 cm; BMI: 26.02 ± 2.5 kg/m2). The RT protocol consisted of 6 bench press sets to failure at 80% of 8 repetitions maximum, with a 1-minute rest interval between sets. During the rest interval, the TRT group remained resting, while the SRT group was submitted to shoulder anterior chain muscles stretching.ResultsThe results revealed a higher increase in lactate (32%) and total leukocytes (17%) immediately following exercise in the SRT group as compared with the TRT group (<i>p</i> < 0.05). An increase in total testosterone and cortisol was observed in both groups, without differences between them (<i>p</i> > 0.05). There was a progressive decrease in the total number of repetitions completed along sets, without differences between groups.ConclusionsThe use of agonist stretching between sets increases the acute metabolic response during an RT session, which could be useful to intensify RT in trained participants.
Psychometric characteristics and measurement invariance across genders of the Multidimensional Scale of Perceived Social Support (MSPSS) among Nigerian adolescents

Published: March 2019

BackgroundThe Multidimensional Scale of Perceived Social Support (MSPSS) in terms of its factor structure, reliability, va-lidity and measurement invariance across genders has not been examined among Nigerian adolescents.Participants and procedureWe evaluated the psychometric properties and gender invariance of the MSPSS among Nigerian senior high school adolescents (N = 1335, M<sub>age</sub> = 15.15). Other study measures completed were the Hospital Anxiety and Depression Scale (HADS), the Positive and Negative Suicide Ideation Inventory (PANSI), and the Rosenberg Self-Esteem Scale (RSES). The four models of the MSPSS described in the literature were com-pared with confirmatory factor analysis (CFA). The model with the best fit indices was examined for its internal consistency by calculating the MacDonald’s omega (ω) while criterion validity was examined through correla-tional analyses with other study measures. Measurement invariance in relation to gender was assessed with multi-group nested CFA.ResultsOur results confirmed the original 3-factor structure of the MSPSS (Family, Significant others, and Friends). CFA showed that our data equivalently fitted the first (original first order 3-factor) and the fourth (second order 3-factor) MSPSS models. The reliability and criterion validity were satisfactory. Configural, metric and scalar measurement invariances in relation to genders were confirmed.ConclusionsThe 3-factor MSPSS either in its original (first-order) or second-order model is useful as a perceived social support assessment instrument among Nigerian adolescents.
