In Disguise or Out of Reach: First Clues about In Situ and Accreted Stars in the Stellar Halo of the Milky Way from Gaia DR2
Authors: Haywood M. , Di Matteo P. , Lehnert M. D. , Snaith O. , Khoperskov S. , Gómez A. 
Published: August 2018

Abstract
We investigate the nature of the double color–magnitude sequence observed in the Gaia DR2 HR diagram of stars with high transverse velocities. The stars in the reddest-color sequence are likely dominated by the dynamically hot tail of the thick disk population. Information from Nissen & Schuster and from the APOGEE survey suggests that stars in the blue-color sequence have elemental abundance patterns that can be explained by this population having a relatively low star formation efficiency during its formation. In dynamical and orbital spaces, such as the “Toomre diagram,” the two sequences show a significant overlap, but with a tendency for stars on the blue-color sequence to dominate regions with no or retrograde rotation and high total orbital energy. In the plane defined by the maximal vertical excursion of the orbits versus their apocenters, stars of both sequences redistribute into discrete wedges. We conclude that stars that are typically assigned to the halo in the solar vicinity are actually both accreted stars lying along the blue sequence in the HR diagram, and the low rotational velocity tail of the old Galactic disk, possibly dynamically heated by past accretion events. Our results imply that a halo population formed in situ and responsible for the early chemical enrichment prior to the formation of the thick disk has yet to be robustly identified, and that what has been defined as the stars of the in situ stellar halo of the Galaxy may in fact be fossil records of its last significant merger.
Fluctuation Dynamo in a Collisionless, Weakly Magnetized Plasma
Authors: St-Onge Denis A. , Kunz Matthew W. 
Published: August 2018

Abstract
Results from a numerical study of fluctuation dynamo in a collisionless, weakly magnetized plasma are presented. The key difference between this dynamo and its magnetohydrodynamic (MHD) counterpart is the adiabatic production of magnetic-field-aligned pressure anisotropy by the amplification of a weak seed field. This, in turn, drives kinetic instabilities on the ion-Larmor scale—namely, firehose and mirror—which sever the adiabatic link between the thermal and magnetic pressures, thereby allowing the dynamo to proceed. After an initial phase of rapid growth driven by these instabilities, the magnetic energy grows exponentially and exhibits a

spectrum that peaks near the resistive scale, similar to the large-magnetic-Prandtl-number (

) MHD dynamo. The magnetic field self-organizes into a folded-sheet topology, with direction reversals at the resistive scale and field lines curved at the parallel scale of the flow. The effective

is determined by whether the ion-Larmor scale is above or below the field-reversing scale: in the former case, particles undergo Bohm-like diffusion; in the latter case, particles scatter primarily off of firehose fluctuations residing at the ends of the magnetic folds, and the viscosity becomes anisotropic. The magnetic field ultimately saturates at dynamical strengths, with its spectral peak migrating toward larger scales. This feature, along with an anti-correlation of magnetic-field strength and field-line curvature and a gradual thinning of magnetic sheets into ribbons, resembles the saturated state of the large-

dynamo, the primary differences manifesting in firehose/mirror-unstable regions. These results have implications for magnetic-field growth in the weakly collisional intracluster medium of galaxy clusters.

Leadership styles and relational energy: Do all leaderships styles generate and transmit equal relational energy?
Authors: Amah Okechukwu E. 
Published: August 2018

Background: Despite the espoused importance of relational energy, and the fact that it is generated in interaction between leaders and their subordinates, little is known about which leadership style generates the highest relational energy.Objectives: The purpose of this study was to determine if there are differences in the levels of relational energy generated and transmitted when employees interact with leaders who exhibit autocratic, transactional, transformational and servant leadership styles.Method: The study utilised scenario-based experimental methodology to gather data. Five leadership experts reviewed the description of each leadership style prior to use in the study. A pilot study was carried out with 40 executive education participants to establish that the description of each leadership style was different and identifiable by non-experts. Fifty-two executive Master of Business Administration (MBA) participants from various organisations in six industries in Lagos, Nigeria, provided data for the scenario analysis. To avoid errors, the data for each style were collected separately. Data analysis was performed using analysis of variance and Tukey’s honest significant difference test.Results: The results of the scenario analysis showed that indeed there is a difference in the relational energy generated when employees interact with different leadership styles.Conclusion: The results have practical implications for the selection and training of individuals to be placed in leadership positions. Leadership selection and training must emphasise servant leadership. This is the first study to empirically establish that different leadership styles generate and transmit different levels of relational energy during interaction with employees.

Prostate cancer metastatic to the planum sphenoidale presenting as sequential bilateral vision loss
Authors: Yohannan Binoy , Feldman Mark 
Published: August 2018

Metastasis to the anterior cranial fossa from solid tumors is very unusual. We describe a 72-year-old male with history of locally advanced prostate cancer who presented with sequential bilateral vision loss, initially misdiagnosed and mistreated as giant cell arteritis. Neuroimaging eventually revealed an extra-axial soft tissue mass in the planum sphenoidale exerting a pressure effect on the cisternal segments of the optic nerves. He underwent surgical excision of the mass to try to improve his vision. Biopsy results confirmed high grade metastatic adenocarcinoma of the prostate. He was started on high dose glucocorticoids and radiation therapy and his visual symptoms improved. Patients with metastatic prostate cancer can develop cranial nerve deficits secondary to metastatic involvement of the skull base. Early recognition and appropriate therapy is essential to prevent permanent neurological impairment.
Effect of acetylcholine, pilocarpine, serotonin and adrenaline on the in vitro gastric motility of Hoplias malabaricus (Teleostei)
Authors: Vieira Vânia L. Pimentel , Baldisserotto Bernardo , Krause Sílvia 
Published: August 2018

The in vitro effect of acetylcholine, pilocarpine, serotonina and adrenaline on gastric motility of the teleost Hoplias malabaricus was studied. The stomach of this specieshas spontaneous contractile activity, with no relationship between tension or frequency of contrations and fish weight. Acetylcholine reduced the frequency of contrations at higher concentrations, but had not effect at lower concentrations. The higher doses of this drug increased the tension and tonus of the contrations. Pilocarpine increased the frequency and tension of contractions at higher concentrations, but had not effect at lower concentrations, and increased tonus only at the concentration of 10-7 M. A significant correlation between the doses of acetylcholine and policarpine and tension of gastric contractions was found. Adrenaline and serotonina had not effect on the frequency, tension and tonus of the stomach contractions. The results obtained with acetylcholine and policarpine demonstrate that the stomach of H. malabaricus has muscarinic cholinoceptors. The results obtained with adrenaline and serptonin did not demonstrate the existence of adrenergic or serotonergic receptors in the stomach of this species.
Alu hypermethylation and high oxidative stress in patients with musculoskeletal tumors
Authors: Woraruthai Thamonwan , Charoenlap Chris , Hongsaprabhas Chindanai , Mutirangura Apiwat , Honsawek Sittisak 
Published: August 2018

Background
Alu is one of the non-autonomous element retrotransposons, constituting nearly 11% of the human DNA. Methylation changes of the Alu element can cause genomic instability, a hallmark of cancer development, ultimately leading to the development of cancer. Epigenetic factors may induce the aberrant methylation of Alu and also oxidative stress. However, current knowledge of Alu methylation and oxidative stress is limited. There are few studies that have evaluated Alu methylation and oxidative stress on musculoskeletal tumor progression. Therefore, the present study evaluated the status of Alu methylation in musculoskeletal (MS) tumor, adjacent tissues, and blood leukocytes from MS tumor subjects, as well as unaffected participants. Moreover, we also investigated the oxidative stress status in MS tumor subjects and the control participants and determined the correlation between Alu methylation in MS tumors and that in blood leukocytes.

Methods
Musculoskeletal tumors from musculoskeletal tumor patients (n = 40) were compared to adjacent tissues (n = 40). The blood leukocytes from musculoskeletal tumor patients were compared to the blood leukocytes from controls (n = 107). Alu methylation status was analyzed using quantitative combined bisulfite restriction analysis (COBRA). In addition, 8–hydroxy 2′–deoxyguanosine (8–OHdG) values were determined using enzyme—linked immunosorbent assay.

Results
Alu methylation values in MS tumors were statistically significantly higher than those in adjacent tissues (P = 0.035). Similarly, Alu methylation statuses in the blood leukocytes of MS tumor subjects were statistically greater than those of control participants (P < 0.001). Moreover, there was a positive association between Alu methylation levels in MS tumors and blood leukocytes (r = 0.765, P < 0.001). In addition, the highest tertile was significantly associated with the risk of MS tumors (OR = 14.17, 95% CI [5.08–39.51]; P < 0.001). The 8-OHdG values in MS tumors were statistically higher than in adjacent tissues (P < 0.001) and circulating 8-OHdG levels were substantially greater in MS tumor subjects than in the control participants (P < 0.001).

Discussion
These findings suggest that Alu methylation in blood leukocytes and plasma 8-OHdG might represent non-invasive biomarkers to help diagnose MS tumors. Therefore, Alu hypermethylation and high oxidative stress might be involved in the pathogenesis of the musculoskeletal tumors.
A hybrid volumetric dose verification method for single‐isocenter multiple‐target cranial SRS
Authors: Ahmed Saeed , Kapatoes Jeff , Zhang Geoffrey , Moros Eduardo G. , Feygelman Vladimir 
Published: August 2018

AbstractA commercial semi‐empirical volumetric dose verification system (PerFraction [PF], Sun Nuclear Corp.) extracts multi‐leaf collimator positions from the electronic portal imaging device movies collected during a pre‐treatment run, while the rest of the delivered control point information is harvested from the accelerator log files. This combination is used to reconstruct dose on a patient CT dataset with a fast superposition/convolution algorithm. The method was validated for single‐isocenter multi‐target SRS VMAT treatments against absolute radiochromic film measurements in a cylindrical phantom. The targets ranged in size from 0.8 to 3.6 cm and in number from 3 to 10 per plan. A total of 17 films rotated at different angles around the cylinder axis were analyzed. Each of 27 total targets was intercepted by at least one film, and 2–4 different films were analyzed per plan. Film dose was always scaled to the ion chamber measurement in a high‐dose, low‐gradient area deliberately created at the isocenter. The planar dose agreement between PF and film using 3%(Global dose‐difference normalization)/1 mm gamma analysis was on average 99.2 ± 1.1%. The point dose difference in the low‐gradient area in the middle of every target was below 3%, while PF‐reconstructed and film dose centroids for individual targets showed submillimeter agreement when measured on a well aligned accelerator. Volumetrically, all voxels in all plans agreed between PF and the primary treatment planning system at the 3%/1 mm level. With proper understanding of its advantages and shortcomings, the tool can be applied to patient‐specific QA in routine radiosurgical clinical practice.

AbstractSince the birth of quantum mechanics the construction and control of novel hybrid quantum states are among the dream targets of scientists. In this regard, due to recent technological advances, hybrid states based on strong coupling occurring between light and matter have become a laboratory reality. For example, it is demonstrated that strong coupling involving microcavities or surface plasmon polaritons shows great potential for novel nanoplasmonic devices such as lasers, all‐optical switching, field‐effect transistors, and for the evergreen field of quantum computation. Further developments in this field require, however, a better understanding of the underlying mechanisms governing strong coupling, especially from a time‐dependent point of view, time‐resolved spectroscopy being one of the leading experimental approaches to address this aspect. In this perspective, after a brief introduction of the strong coupling concept, the recent research progress on the dynamics of strongly coupled systems involving J‐aggregates, broadly absorptive dyes, semiconductor quantum dots, and perovskite films with either microcavities or surface plasmons polaritons is summarized and discussed. Finally, challenges and perspectives for developing strong coupling concept are further illustrated, with special attention to phonon–photon interaction, as one of the most intriguing topics in condensed matter physics.

Published: August 2018

AbstractPhotocatalysis for solar‐driven reactions promises a bright future in addressing energy and environmental challenges. The performance of photocatalysis is highly dependent on the design of photocatalysts, which can be rationally tailored to achieve efficient light harvesting, promoted charge separation and transport, and accelerated surface reactions. Due to its unique feature, semiconductors with hollow structure offer many advantages in photocatalyst design including improved light scattering and harvesting, reduced distance for charge migration and directed charge separation, and abundant surface reactive sites of the shells. Herein, the relationship between hollow nanostructures and their photocatalytic performance are discussed. The advantages of hollow nanostructures are summarized as: 1) enhancement in the light harvesting through light scattering and slow photon effects; 2) suppression of charge recombination by reducing charge transfer distance and directing separation of charge carriers; and 3) acceleration of the surface reactions by increasing accessible surface areas for separating the redox reactions spatially. Toward the end of the review, some insights into the key challenges and perspectives of hollow structured photocatalysts are also discussed, with a good hope to shed light on further promoting the rapid progress of this dynamic research field.
Single‐Crack‐Activated Ultrasensitive Impedance Strain Sensor
Authors: Ye Jilong , Yang Tingting , Zhang Yafei , Lin Li 
Published: August 2018

AbstractA development of single‐crack‐activated impedance strain sensors with unprecedented sensitivity is demonstrated first. The gauge factor of the device is beyond 108 in 10−4 strain range in comparison with the reported highest gauge factor 1.5 × 105 within 6e‐1 strain range, and the displacement sensitivity is 1.6 MΩ nm−1. The extremely high sensitivity is attributed to the transition region which has never been studied before. Multiple‐crack‐based sensors, however, cannot work in the transition region due to complicated interaction among cracks, which essentially limits their sensitivity. Additionally, studying a precisely controllable single crack rather than multiple cracks is favorable for excluding other factors such as crack spacing, difference among cracks, and interaction among cracks, simplifying the model and facilitating better understanding of the underlying mechanism of the device. The device can satisfy requirements of mechanical flexibility, durability, and repeatability. In addition, the device developed is capable of measuring displacement in nanometers range or force in tens of nanonewton range, and has the potential to be applied in various fields, such as specific biomolecular recognition.
