Simulations of energy dissipation and non-thermal desorption on amorphous solid water

Abstract Dust particles covered by icy mantles play a crucial role in the formation of molecules in the Interstellar Medium (ISM). These icy mantles are mainly composed of water but many other chemical species are also contained in these ices. These compounds can diffuse and meet each other to react. It is through these surface reactions that new saturated species are formed. Photodissociation reactions are also thought to play a crucial role in the formation of radical species. Complex organic molecules are formed through an intricated network of photodissociation and surface reactions. Both type of reactions release energy. Surface reactions are typically exothermic by a few eV, whereas photodissociation reactions are triggered by the absorption of a UV photon, resulting in the formation of highly excited products. The excited reaction products can apply this energy for desorption or diffusion, making products more mobile than predicted when considering only thermal hopping. The energy could further lead to annealing or deformation of the ice structure. Here we would like to quantify the relative importance of these different energy dissipation routes. For this we performed thousands of Molecular Dynamics simulations for three different species (CO2, H2O and CH4) on top of a water ice surface. We consider different types of excitation such as translational, rotational, and/or vibrational excitation. The applied substrate is an amorphous solid water surface (ASW).
Towards a new paradigm of dust structure in AGN: Dissecting the mid-IR emission of Circinus galaxy

Abstract Recent mid-infrared (MIR) observations of nearby active galactic nuclei (AGN), revealed that their dust emission appears prominently extended in the polar direction, at odds with the expectations from the canonical dusty torus. This polar dust, tentatively associated with dusty winds driven by radiation pressure, is found to have a major contribution to the MIR flux from a few to hundreds of parsecs. One such source with a clear detection of polar dust is a nearby, well-known AGN in the Circinus galaxy. We proposed a phenomenological model consisting of a compact, thin dusty disk and a large-scale polar outflow in the form of a hyperboloid shell and demonstrated that such a model is able to explain the peculiar MIR morphology on large scales seen by VLT/VISIR and the interferometric data from VLTI/MIDI that probe the small scales. Our results call for caution when attributing dust emission of unresolved sources entirely to the torus and warrant further investigation of the MIR emission in the polar regions of AGN.
Mentoring: The Consequences of Formalization in the Age of Corporatization

Much has changed in the US system of higher education since I entered graduate school in 1978. The social–structural forces producing these changes are familiar and include, among other things, decreasing support for public institutions, which has spurred dramatic growth of college and university fundraising offices. These structural and resulting cultural changes have been summarized as “corporatization” (Donoghue 2008), the “audit culture” (Strathern 2000), and the “neoliberal university. ” What this research shows is that universities have been transformed to fit the globalizing, marketizing capitalist world, and that hasmeant an increasing emphasis on themeasurement of faculty “productivity,” coupled with a speed-up of the pace of academic life. The effects of these macro forces have been sweeping, yet uneven—with variation by type of institution, public support for the tenure system and academic freedom, and faculty organizing. Still, over this time period, many of the changes have spread widely and, tellingly, have become normalized to the extent that they now seem reasonable or even desirable to newer generations of academics. These decades-long transformations have also affectedmentoring.Whatwas once an informal activity arising organically in day-to-day practices—what I experienced early inmy career—has become formalized.Whether sponsored by departments, deans, or graduate schools, formal mentoring programs seem to be increasing. Since 2007, there exists a Mentoring Institute at the University of New Mexico (see https://mentor.unm.edu), complete withworkshops, annual conferences, online resources, etc. What motivates this interest? Why has mentoring become formalized in the ways that it has and with what consequences? This article analyzes these changes in mentoring of graduate students and junior faculty. First, I review motivations for this interest, describe my own experiences as a mentee and a mentor, and provide evidence of online resources to show how formal mentoring is conceptualized. The second section takes a critical turn, interrogating the ways in which the selected evidence is indicative of the corporatization of the university that, itself, is undermining the academic culture that makes mentoring viable. Third, I conclude with an analysis of corporatized management practices to make the general case that collective forms of mentoring should be chosen over individualized programs.

The chemistry of episodic accretion

Abstract Episodic accretion is an important process in the evolution of young stars and their surroundings. A consequence of an episodic accretion event is a luminosity burst, which heats the protostellar environment and has a long lasting impact on the chemical evolution of the disk and envelope of young stars. We present a new model for the chemistry of episodic accretion based on the 2D radiation thermo-chemical disk code ProDiMo. We discuss the impact of an episodic accretion burst on the chemical evolution of CO and its observables. Furthermore we present a model for the outbursting source V883 Ori where we fitted available observational data to get an accurate physical structure that allows for a detailed study of the chemistry.
Predicting Listed Firms’ Financial Statement Fraud Risk in the Vietnamese Securities Market

This paper focuses on fraud risk and identifying factors that affect the risk of financial reporting fraud of listed companies in Vietnam, and on forecasting the possibility of fraudulent financial statements of listed companies in Vietnam. Based on M-score and F-score models and an experimental survey of the research sample of 3,684 financial statements made by 307 companies in the period 2007-2008, the paper indicates that the higher the financial statements are, the more fraud occurs in the statements. Also, the older and larger the companies are, and the longer they have been listed on the stock exchange market, the more fraudulent their financial statements are likely to be.
Surface-Confined Synthesis of One-Dimensional Schiff Base Polymers Investigated by Scanning Tunneling Microscopy

The surface-mediated synthesis of ordered linear or zigzag polymers on a highly oriented pyrolytic graphite surface was investigated either at a solid/liquid interface or with moderate heating under low vacuum. Scanning tunneling microscopy (STM) reveals the submolecular details of the structure and growth dynamics of surface-confined one-dimensional polymers. We discovered that the substituent and concentration of monomers have a significant effect on the assembling structure of the in-situ-synthesized one-dimensional polymer at the octanoic acid/graphite interface.
Practitioner's view: A comparison and a survey of lemmatization and morphological tagging in German and Latin

The challenge of POS tagging and lemmatization in morphologically rich languages is examined by comparing German and Latin. We start by defining an NLP evaluation roadmap to model the combination of tools and resources guiding our experiments. We focus on what a practitioner can expect when using state-of-the-art solutions. These solutions are then compared with old(er) methods and implementations for coarse-grained POS tagging, as well as fine-grained (morphological) POS tagging (e.g. case, number, mood). We examine to what degree recent advances in tagger development have improved accuracy – and at what cost, in terms of training and processing time. We also conduct in-domain vs. out-of-domain evaluation. Out-of-domain evaluation is particularly pertinent because the distribution of data to be tagged will typically differ from the distribution of data used to train the tagger. Pipeline tagging is then compared with a tagging approach that acknowledges dependencies between inflectional categories. Finally, we evaluate three lemmatization techniques.
A search for new γ-ray blazars from infrared selected candidates

Abstract We present a systematic study of gamma-ray blazar candidates based on a sample of 40 objects taken from the WIBR catalogue. By using a likelihood analysis, 26 of the 40 sources showed significant gamma-ray signatures ⩾ 3σ. Using high-energy test statistics (TS) maps, we confirm 8 sources, which are completely new, and show another 15 promising γ-ray candidates. The results from this analysis show that a multi-frequency approach can help to improve the current description of the gamma-ray sky.
The relationship between black hole accretion rate and gas properties at the Bondi radius

Abstract The mass accretion rate determines the black hole accretion mode and the corresponding efficiency of active galactic nuclei (AGNs) feedback. In large-scale simulations studying galaxy formation and evolution, the Bondi radius can be at most marginally resolved. In these simulations, the Bondi accretion formula is always used to estimate the black hole accretion rate. The Bondi solution can not represent the real accretion process. We perform 77 simulations with varying density and temperature at Bondi radius. We find a formula to calculate the black hole accretion rate based on gas density and temperature at Bondi radius. We find that the formula can accurately predict the luminosity of observed low-luminosity AGNs. This formula can be used in sub-grid models in large-scale simulations with AGNs feedback.
An Empirical Study of Customers’ Satisfaction and Repurchase Intention on Online Shopping in Vietnam

This study aims to examine the factors that affect customer satisfaction and repurchase intention of online shoppers in Vietnam. We used the anklet method to collect information by sending the online questionnaire to Vietnamese people via social media like Facebook, Zalo, and instructed participants to fill out the survey. This study collected data randomly from 597 Vietnamese individuals who have experienced online shopping. Applying both qualitative and quantitative methods, we investigated the impacts of factors (responsiveness, trust, convenience, delivery, information quality and perceived website usability) on customer satisfaction and repurchase intention. The results revealed that: (1) Information quality, delivery, convenience, and perceived website usability have the most significant impacts on customer satisfaction and intention, (2) Trust moderately affects satisfaction and repurchase intention, (3) Responsiveness has no significant influence on repurchase intention and (4) Control variables, included gender and marital status also impacted satisfaction and repurchase intention because the study found that male customers are more satisfied than female customers and single people tend to repurchase at familiar websites more than the other people. The findings suggested that six mentioned factors have different levels of impacts on customer satisfaction and repurchase intention; moreover, the demographic factors also affect satisfaction and intention to repurchase.
Luminous and dark matter density profiles in the inner regions of a group-scale lens at z = 0.6

Abstract Density profiles of galaxy groups can provide an insight on how large-scale structure in the Universe formed and evolved, since galaxy groups bridge the gap between individual galaxies and galaxy clusters. Studying the galaxy group that is gravitational lensing HELMS18, a submillimeter galaxy at z = 2.39 from the Herschel’s HerMES Large Mode Survey (HELMS), we aim to probe the total density profile by combining strong gravitational lensing with kinematics of the centrally-located galaxies and kinematics of the group members. We have high-resolution data of HELMS18 obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) and multi-object spectroscopic data of the group members from Gemini-GMOS. Our main goal is to match these observations to probe the DM and stellar density profiles and to establish a complete description of this galaxy group.
The horizontal (tangential) fibres system of lamina I of the cerebral neocortex.

: Lamina I has two principal components: a meshwork of fine unmyelinated fibres, the so-called horizontal fibres (h.f.); the profusely branching apical dendrites of all pyramidal cells. These dendrites are studded with spines on which the h.f. 's make excitatory synapses in a crossing-over manner. The h.f. system is produced by the fibres that ascend through the modules and bifurcate in lamina I, each branch extending for up to 5 mm from its origin. These ascending fibres are axons of Martinotti cells, and of corticocortical fibre inputs to the module, both ipsilateral and callosal. Electrophysiological investigations have shown that the h.f. system has a powerful excitatory action on the pyramidal cells. There will be developed the hypothesis that the h.f. -pyramidal dendrite system of lamina I is a structure specially designed for the storage of memories. Conjunction of cartridge activation of pyramidal cell dendrites with a selection of impulses in h.f. 's could produce a synaptic potentiation encoding the experience that is dependent on that selection of h.f. impulses. On a later occasion these potentiated synapses could be effective in replaying the coded neuronal pattern and so retrieving the memory.
Robust LMI-Based Active Fault Tolerant Pitch Control of a Wind Turbine Using a Fuzzy Model

This article seeks to investigate a robust active fault-tolerant control strategy for a wind turbine system in the presence of actuator and sensor fault. The state-space representation of the system was formulated by the Takagi-Sugeno fuzzy model and then, a disturbance rejection technique is used to eliminate the wind perturbation. To guarantee the robust behavior of the system, the control signal is reconfigured through adding a robust term. By using the Lyapunov method, some criteria, which are expressed in the form of linear matrix inequalities (LMIs), are provided for asymptotic stability of the estimated error. Finally, the main results were confirmed by numerical simulations of a 1 MW wind turbine.
Two-sided Markets and Matching Design

Two-sided markets are markets in which agents match through a platform, which designs and prices matching opportunities. Typical examples include ad-exchanges matching advertisers with publishers; media outlets matching readers/viewers with content providers and advertisers; video-game consoles matching gamers with game developers; operating systems matching end-users with software developers; e-commerce websites matching buyers with sellers; business-to-business platforms matching procurers with service providers; and employment agencies matching employers with job seekers. In the last few years, platform markets have gained a prominent role in the organization of business activities. As a result, a conspicuous literature has flourished examining various aspects of such markets, ranging from pricing to platform design. In this chapter, we focus on monopolistic pricing and its connection to matching design. Section 2 contains a flexible model of platformmediated matching with transfers. Section 3 reviews some of the classical results on monopolistic pricing in two-sided markets. Section 4 extends some of these results to markets in which both the platform and the agents face uncertainty over the distribution of preferences over the two sides of the market and hence over the eventual participation decisions. Section 5 considers markets in which the platform engages in discriminatory practices matching different agents to different subsets of the participating agents from the other side of the market. It first considers the case of one-to-one matching and then the case of manyto-many matching. Throughout the entire chapter, special attention is given to the distortions in the provision of matching services that emerge in two-sided markets when the platform enjoys significant market power.

Kinematics of z ∼ 4–6 Lyman break galaxies in ALPINE

Abstract The past century has seen massive improvements in the study of galaxy kinematics. While early work focused on single nearby galaxies, current studies with modern IFUs and interferometers (e.g., SINFONI, ALMA) allow for extension of this field to high redshift. However, the sample of galaxy observations at z > 4 that feature the sensitivity and resolution required for resolved dynamical characterization has been small. The ALMA Large Program to INvestigate CII at Early times (ALPINE) targeted 118 star-forming galaxies at z = 4–6, representing a vast increase in the sample size of potentially dynamically-characterizable sources. Using a set of diagnostic plots, we are able to characterize roughly half the sample, revealing a vast kinematic diversity and high merger rate. For the nine targets that show rotational signatures, initial tilted ring fitting with 3DBarolo shows promise. With further observations (e.g., ALMA, NOEMA, MUSE), the true nature of each source will be revealed in unprecedented detail.
Uncovering the spatial distribution of stars and dust in z ∼ 2 Submillimeter Galaxies

Abstract The spatial distribution of the dust and stars contains crucial information about the evolutionary pathways of galaxies. We present results of our study combing high-resolution ALMA and HST observations of z ∼ 2 bright sub-millimeter galaxies (SMGs). We have developed a two-dimensional extinction and age correction technique to obtain accurate stellar mass distributions from HST/CANDELS. For the first time, we can directly compare the spatial distribution of assembled stellar mass and ongoing star formation on kpc scales for distant SMGs, shedding light on their highly debated formation mechanisms. We find that the dust distribution is more compact than the stellar component, regardless if the SMG lies on the main sequence or at the starburst regime. Taking the dust emission as a proxy for dust-obscured star formation, our results imply that high-redshift SMGs are experiencing centrally enhanced star formation. These findings suggests that major galaxy interactions are not necessarily the main formation channel for SMGs with secular disk formation remaining a viable option as suggested by state-of-the-art cosmological simulations. The sizes and stellar densities of our z ∼ 2 SMGs agree well with the most compact early-type galaxies in the local Universe, strongly supporting the idea that the latter systems are indeed the descendants of massive SMGs at z ∼ 2.
Child obesity and dentistry

Childhood obesity is one of the fastest growing epidemics in the world. It used to be a problem limited to developed countries but has slowly, but surely, made its way into developing nations. 7 out of 1 children nowadays are overweight, if not obese. Obesity not only affects systemic, but also dental health negatively. Since the biggest contributor to this problem is diet, dentist are in aunique position to not only monitor but also control childhood obesity. In this article, there is description of various problems faced by an obese person and the various ways in which a dentist can help them.
High-pressure elasticity of a natural magnetite crystal

Abstract Variation of the sound velocities, elastic constants, and compressibility of a natural magnetite crystal were determined using gigahertz ultrasonic interferometry and single-crystal X-ray diffraction to 8.7 GPa. At ambient pressure, the elastic constants are (in GPa): c11 = 260.5(1.0), c12 = 148.3(3.0), and c44 = 63.3(1.5). While c11 and c12 have similar positive pressure derivatives of 5.14(13) and 5.39(10), respectively, the c44 elastic constant exhibits mode-softening over this pressure range, with dc44/dP = -0.13(4), calculated from the pressure dependence of the [100] shear velocity. The adiabatic bulk modulus (K0S) is 185.7(3.0) GPa, with KS = 5.1(1), and the shear modulus (G0) is 60.3(3.0) GPa, with G′ = -0.1(1). The bulk modulus and its pressure derivative obtained dynamically are consistent with the isothermal equation of state, measured on the same sample by single-crystal X-ray diffraction, yielding K0T = 180.0(1.0) and K′T = 5.2(4). Pressure-induced shear-mode softening in magnetite is most likely related to magnetoelastic coupling and the first-order phase transition to an orthorhombic structure above 21 GPa.
Teaching Introductory American Politics as Part of a Learning Community

D the fall of 1998, I took part in an experimental learning community involving my introduction to American politics class, "The American Political System" (POLS001). Robert Hariman, professor of rhetoric and mass communication, and Ronald Troyer, dean of the College of Arts and Sciences, also participated. We judged it to be a success and we repeated it in the fall of 1999. In this article I report on that experiment, detailing what went well with it and what did not, and also make some observations about how what I learned while participating in this experiment might help me better design and conduct more "typical" introductory American politics classes. Calls for improving undergraduate education by creating "learning communities" have been common since the early 1990s. ' This phrase seems to mean something different to everyone who discusses it, but the common goal of learning community organizers is to bring students together in ways that will broaden their educational experience and make their classes more than a series of requirements they meet on their way to a degree. The literature on learning communities is growing rapidly, as are attempts to create them. Researchers with experience in learning communities have argued that such programs can help with retention, meet general education objectives, foster student success, and bring coherence to student class schedules (Matthews
Synthesis of Se/chitosan-derived hierarchical porous carbon composite as Li–Se battery cathode

The hierarchical porous carbon with overall macropores and surface micropores has been prepared from carbonization of chitosan/K2CO3 gel-like composite. The specific surface area and pore volume of this carbon can come to 2358.9m2 g−1 and 1.14cm3 g−1, respectively, and the active component Se with amorphous structure is uniformly encapsulated into the microporous structure to form Se/carbon composite. As Li–Se battery cathode, the composite delivers a second discharge capacity of 537.6mAh g−1 at 0.2C, and a discharge capacity of 517.9mA h g−1 can be retained after 100 cycles. Even at a high rate of 5C, the composite still reveals a stable discharge capacity of 325.2mAh g−1. The excellent electrochemical performances of Se/carbon composite may attribute to high specific surface area and hierarchical porous feature.
