description: In model studies of aerosol-dependent immersion freezing in clouds, a common assumption is that each ice nucleating aerosol particle corresponds to exactly one cloud droplet. In contrast, the immersion freezing of larger drops—“rain”—is usually represented by a liquid volume-dependent approach, making the parameterizations of rain freezing independent of specific aerosol types and concentrations. This may lead to inconsistencies when aerosol effects on clouds and precipitation shall be investigated, since raindrops consist of the cloud droplets—and corresponding aerosol particles—that have been involved in drop-drop-collisions. Here we introduce an extension to a two-moment microphysical scheme in order to account explicitly for particle accumulation in raindrops by tracking the rates of selfcollection, autoconversion, and accretion. This provides a direct link between ice nuclei and the primary formation of large precipitating ice particles. A new parameterization scheme of drop freezing is presented to consider multiple ice nuclei within one drop and effective drop cooling rates. In our test cases of deep convective clouds, we find that at altitudes which are most relevant for immersion freezing, the majority of potential ice nuclei have been converted from cloud droplets into raindrops. Compared to the standard treatment of freezing in our model, the less efficient mineral dust-based freezing results in higher rainwater contents in the convective core, affecting both rain and hail precipitation. The aerosol-dependent treatment of rain freezing can reverse the signs of simulated precipitation sensitivities to ice nuclei perturbations.

description: We analyzed observations of interstellar neutral helium (ISN~He) obtained from the Interstellar Boundary Explorer (IBEX) satellite during its first six years of operation. We used a refined version of the ISN~He simulation model, presented in the companion paper by Sokol_et al. 2015, and a sophisticated data correlation and uncertainty system and parameter fitting method, described in the companion paper by Swaczyna et al 2015. We analyzed the entire data set together and the yearly subsets, and found the temperature and velocity vector of ISN~He in front of the heliosphere. As seen in the previous studies, the allowable parameters are highly correlated and form a four-dimensional tube in the parameter space. The inflow longitudes obtained from the yearly data subsets show a spread of ~6 degree, with the other parameters varying accordingly along the parameter tube, and the minimum chi-square value is larger than expected. We found, however, that the Mach number of the ISN~He flow shows very little scatter and is thus very tightly constrained. It is in excellent agreement with the original analysis of ISN~He observations from IBEX and recent reanalyses of observations from Ulysses. We identify a possible inaccuracy in the Warm Breeze parameters as the likely cause of the scatter in the ISN~He parameters obtained from the yearly subsets, and we suppose that another component may exist in the signal, or a process that is not accounted for in the current physical model of ISN~He in front of the heliosphere. From our analysis, the inflow velocity vector, temperature, and Mach number of the flow are equal to lambda_ISNHe = 255.8 +/- 0.5 degree, beta_ISNHe = 5.16 +/- 0.10 degree, T_ISNHe = 7440 +/- 260 K, v_ISNHe = 25.8 +/- 0.4$ km/s, and M_ISNHe = 5.079 +/- 0.028, with uncertainties strongly correlated along the parameter tube.

Toward a Visual Language for Abstract Ideas: Effect of Concepts on Perception of Symbols

description: In our society, there is an ever-increasing demand for media, and the need, as much as ever, for ordinary people to think critically about ideas.  This paper presents the first steps toward the creation of a visual language that might convey these ideas to an educational software or infographic audience.  Since the problem I am trying to solve is one of agreement over abstract symbols, I conducted a paper questionnaire in which respondents selected shapes that they associated the most with a particular one-word concept.  In most of the questionnaire categories (nature, order, significance, good, anti-, and divinity), most respondents chose one symbol over the other.  Future work is needed to reproduce these results, but the results point to the possibility that we can indeed design a universal visual language of ideas with "dialects" for different cultures.

A Gillespie algorithm for non-Markovian stochastic processes

description: The Gillespie algorithm provides statistically exact methods for simulating stochastic dynamics modelled as interacting sequences of discrete events including systems of biochemical reactions or earthquake occurrences, networks of queuing processes or spiking neurons, and epidemic and opinion formation processes on social networks. Empirically, the inter-event times of various phenomena obey long-tailed distributions. The Gillespie algorithm and its variants either assume Poisson processes (i.e., exponentially distributed inter-event times), use particular functions for time courses of the event rate, or work for non-Poissonian renewal processes, including the case of long-tailed distributions of inter-event times, but at a high computational cost. In the present study, we propose an innovative Gillespie algorithm for renewal processes on the basis of the Laplace transform. The algorithm makes use of the fact that a class of point processes is represented as a mixture of Poisson processes with different event rates. The method is applicable to multivariate renewal processes whose survival function of inter-event times is completely monotone. It is an exact algorithm and works faster than a recently proposed Gillespie algorithm for general renewal processes, which is exact only in the limit of infinitely many processes. We also propose a method to generate sequences of event times with a tunable amount of positive correlation between inter-event times. We demonstrate our algorithm with exact simulations of epidemic processes on networks, finding that a realistic amount of positive correlation in inter-event times only slightly affects the epidemic dynamics.

description: Die Lebensdauer des Elektronenstrahl am Karlsruhe Research Accelerator (KARA) Speichering, Karlsruhe Institute of Technology (KIT) ist hauptsächlich durch die Streuung an Restgasatomen limitiert, wobei auch die Touschek-Streuung zwischen zwei Elektronen des selben Elektronenpakets die Lebensdauer beschränkt. Dieser Effekt hängt direkt von der Elektronendichte ab. In früheren Arbeiten ist bereits herausgefunden worden, dass eine Verlängerung der Elektronenpakete durch eine Modulation der RF Beschleunigungsphase erreicht werden kann, wobei longitudinale Oszillationsmoden innerhalb der Pakete angeregt werden. Um die optimalen Bedingungen zur Einführung der Phasenmodulation (PM) in den Beschleuniger-Betrieb zu finden, ist in dieser Arbeit ist eine erste systematische Untersuchung der (PM) in der Nähe der zweiten Harmonischen der Synchrotronoszillationsfrequenz mit einer Amplitude von 10% bis 20% der synchronen Phase durchgeführt worden. Dabei ist ein besonderer Fokus auf dem Einfluss der Phasenmodulation auf die Paketform, die Paketlänge und folglich die Lebensdauer gelegt worden.

 Distribution in India: Punjab (wider and former undivided Punjab province prior to the Partition of India in 1947).
 Notes: The type locality (Lahore) is commonly given as India. But Lahore is located now in Pakistan. It is a species with a wide distribution reported from tropical mainland North America and Hawaii (Sherwood 2004) to Australia & New Zealand (Bostok & Holland 2010) and Brazil (Necchi et al. 1993b; Zucchi & Necchi 2003). Two categories i.e., reddish and bluish species are recognizable in the genus Audouinella (Necchi et al. 1993b; Zucchi & Necchi 2003). As judged from the description of Desikachary et al. (1990), the specimens based on Skuja’s (1934) original collection, are reddish-violet and belong to the first category. Skinner & Entwisle (2001) provided a detailed description and figures of the Australian specimens and indicated that a “collection (of A. eugenea) was found among the rhizoids at the base of Batrachospermum antipodites and may perhaps be its “ Chantransia ” (or sporophyte) phase”. Carmona & Necchi (2001; see also Carmona & Beltrán 2007) on numerous collections of A. eugenea from Central Mexico and south-eastern Brazil, showed the presence of numerous spermatangia and putative propagules for the first time. These findings suggest that plants identified as “ A. eugenea ” from widely distant geographical latitudes probably include a complex involving different genetic species.

description: We report on the design and experimental characterization of a surface-electrode multipole ion trap. Individual microscopic sugar particles are confined in the trap. The trajectories of driven particle motion are compared with a theoretical model, both to verify qualitative predictions of the model, and to measure the charge-to-mass ratio of the confined particle. The generation of harmonics of the driving frequency is observed as a key signature of the nonlinear nature of the trap. We remark on possible applications of our traps, including to mass spectrometry.

description: The prompt emission of the long, smooth, and single-pulsed gamma-ray burst, GRB $\textit{141028A}$, is analyzed under the guise of an external shock model. First, we fit the $γ$-ray spectrum with a two-component photon model, namely synchrotron+blackbody, and then fit the recovered evolution of the synchrotron $νF_ν$ peak to an analytic model derived considering the emission of a relativistic blast-wave expanding into an external medium. The prediction of the model for the $νF_ν$ peak evolution matches well with the observations. We observe the blast-wave transitioning into the deceleration phase. Further we assume the expansion of the blast-wave to be nearly adiabatic, motivated by the low magnetic field deduced from the observations. This allows us to recover within an order of magnitude the flux density at the $νF_ν$ peak, which is remarkable considering the simplicity of the analytic model. Across all wavelengths, synchrotron emission from a single forward shock provides a sufficient solution for the observations. Under this scenario we argue that the distinction between $\textit{prompt}$ and $\textit{ afterglow}$ emission is superfluous as both early and late time emission emanate from the same source. While the external shock model is clearly not a universal solution, this analysis opens the possibility that at least some fraction of GRBs can be explained with an external shock origin of their prompt phase.

description: We use results from zero-error information theory to determine the set of non-injective functions through which a Markov chain can be projected without losing information. These lumping functions can be found by clique partitioning of a graph related to the Markov chain. Lossless lumping is made possible by exploiting the (sufficiently sparse) temporal structure of the Markov chain. Eliminating edges in the transition graph of the Markov chain trades the required output alphabet size versus information loss, for which we present bounds.

Lattice design of a transfer line for ultra-short bunches from FLUTE to cSTART
Creators: name: Schäfer, Jens
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2019

description: This Master’s Thesis discusses the lattice design of a transfer line for ultra short bunches from FLUTE to cSTART. The compact Storage ring for Accelerator Research and Technology cSTART is a test facility for novel techniques of storing ultra short bunches. The goal of cSTART is to develop a new generation of compact light sources which combine the benefits of linear and circular accelerator facilities, the radiation of short light pulses with a high repetition rate. The Ferninfrarot Linac- und Test-Experiment FLUTE serves as a full energy injector for cSTART, providing bunches with a length of only a few femtoseconds and stable beam parameters. As a consequence of the spatial arrangement of injector and storage ring, a transfer line is required which deflects the bunches in both transverse planes. The unavoidable dispersion affects the path length for off-energy particles and consequentially increases the bunch length. A concept for guiding the FLUTE bunches and avoiding the longitudinal spreading is developed in this thesis, taking into account the technical limitations, coupled transverse optics and non-linear longitudinal beam dynamics. In addition, tracking simulations including radiation effects prove the compression performance of the transfer line.

description: We present the results of models that were designed to study all possible water maser transitions in the frequency range 0-1.91THz, with particular emphasis on maser transitions that may be generated in evolved-star envelopes and observed with the ALMA and SOFIA telescopes. We used tens of thousands of radiative transfer models of both spin species of H2O, spanning a considerable parameter space in number density, kinetic temperature and dust temperature. Results, in the form of maser optical depths, have been summarized in a master table, Table 6. Maser transitions identified in these models were grouped according to loci of inverted regions in the density/kinetic temperature plane, a property clearly related to the dominant mode of pumping. A more detailed study of the effect of dust temperature on maser optical depth enabled us to divide the maser transitions into three groups: those with both collisional and radiative pumping schemes (22,96,209,321,325,395,941 and 1486\,GHz), a much larger set that are predominantly radiatively pumped, and another large group with a predominantly collisional pump. The effect of accelerative and decelerative velocity shifts of up to 5km/s was found to be generally modest, with the primary effect of reducing computed maser optical depths. More subtle asymmetric effects, dependent on line overlap, include maximum gains offset from zero shift by >1km/s, but these effects were predominantly found under conditions of weak amplification. These models will allow astronomers to use multi-transition water maser observations to constrain physical conditions down to the size of individual masing clouds (size of a few astronomical units).

description: Aims: Given the risk of developing vicarious trauma through news media has increased during the pandemic, we explored risk factors associated with media induced secondary trauma, and its behavioral and psychological implications. Methods: An international study (N = 1066), with a diverse sample, was administered in July 2020. We used standardized and validated questionnaires to measure news consumption, media-related trauma, compliance, and paranoia. Results: Greater frequency of news consumption, accessing news via social media and WHO, and believing in conspiracy theories increased likelihood of developing media-induced secondary trauma. News related trauma was associated with greater compliance with safety measures and increased paranoid ideation. Media-trauma however exhibited a greater association with paranoia than compliance. Conclusion: Findings highlight the need to facilitate a collaborative intervention, with public, media houses, health safety officials, and social scientists to have a deeper understanding of potential psychological costs of news consumption patterns

description: We consider the well-travelled problem of homogenization of random integral functionals. When the integrand has standard growth conditions, the qualitative theory is well-understood. When it comes to unbounded functionals, that is, when the domain of the integrand is not the whole space and may depend on the space-variable, there is no satisfactory theory. In this contribution we develop a complete qualitative stochastic homogenization theory for nonconvex unbounded functionals with convex growth. We first prove that if the integrand is convex and has $p$-growth from below (with $p>d$, the dimension), then it admits homogenization regardless of growth conditions from above. This result, that crucially relies on the existence and sublinearity at infinity of correctors, is also new in the periodic case. In the case of nonconvex integrands, we prove that a similar homogenization result holds provided the nonconvex integrand admits a two-sided estimate by a convex integrand (the domain of which may depend on the space-variable) that itself admits homogenization. This result is of interest to the rigorous derivation of rubber elasticity from polymer physics, which involves the stochastic homogenization of such unbounded functionals.

Evidence-based library science

description: The decline in the number of school librarians throughout the United States could have far reaching consequences for students and teachers. In an increasingly digital environment, many believe the school librarian to be an antiquated concept. The development of exceptional library programs through the use of evidence-­based practices cements the role of librarian as valuable instructional and resource partner. The role of the librarian in shaping the attitudes, knowledge, and perceptions of stakeholders directly affects the perception of value. The purpose of this research was to investigate the role of the school librarian in implementing evidence-­based practice through semi structured interviews. Nowhere is this more important than in school libraries where building a strong library program will begin with collecting and disseminating empirical evidence. Interviews revealed that school librarians are participating in collecting and sharing data, but it does not have the same qualities of rigorously methodical science. Library science is, at its core, a social sciences and librarians have managed to create a model for collecting data that applies to the environment where they are teacher, instructional partner, information specialist, and program administrator. The ambivalence regarding whether the collection of data by school librarians should be labeled ‘evidence-based practice’ remains uncertain.

description: The aim of the current paper is to study the multiscalar-tensor theories of gravity without derivative couplings. We construct a few basic objects that are invariant under a Weyl rescaling of the metric and transform covariantly when the scalar fields are redefined. We introduce rules to construct further such objects and put forward a scheme that allows to express the results obtained either in the Einstein frame or in the Jordan frame as general ones. These so called translation rules are used to show that the parametrized post-Newtonian approximation results obtained in the aforementioned two frames indeed are the same if expressed in a general frame.

description: This research project examines employment trends of individuals who are members of the Special Libraries Association (SLA). Data were gathered using the 1993-1994 and 2003-2004 SLA membership directories. These directories reflect the membership demographics of SLA at the beginning and end of a decade. The entire population of SLA employing institutions and their subsequent employees were sorted into twenty-two different categories based on the 2003-2004 SLA Divisions. The data were then used to determine if more job opportunities outside of traditional library settings for SLA members exist today than in past years. Although some of the literature suggests an endless increase in the amount of job opportunities for special librarians, the actual numbers show a different picture. The findings indicate an overall decline in the number of institutions employing special librarians, the total number of special librarians employed in each division, and the total number of SLA membership.

description: While it is often stated that the notion of electroweak (EW) naturalness in supersymmetric models is subjective, fuzzy and model-dependent, here we argue the contrary: electroweak naturalness can be elevated to a {\it principle} which is both objective and predictive. We demonstrate visually when too much fine-tuning sets in at the electroweak scale which corresponds numerically to the measure Δ_{BG}~Δ_{EW}> 30. While many constrained SUSY models are already excluded by this value, we derive updated upper bounds on sparticle masses within the two-extra parameter non-universal Higgs model (NUHM2). We confirm the classic Barbieri-Giudice (BG) result that Δ_{BG}<30 implies mu <350 GeV. However, by combining dependent soft terms which appear as multiples of m_{3/2} in supergravity models, then we obtain m(gluino)< 4 TeV as opposed to the BG result that m(gluino)<350 GeV. We compare the NUHM2 results to a similar scan in the pMSSM with 19 weak scale parameters. In the pMSSM with complete one-loop scalar potential plus dominant two-loop terms, then a m(gluino)<7 TeV bound is found. Our tabulation of upper bounds provides a target for experimenters seeking to discover or else falsify the existence of weak scale supersymmetry. In an Appendix, we show contributions to the naturalness measure from one-loop contributions to the weak scale scalar potential.

 Distribution in India: Kerala (from freshwater flow of Periyar River, near Alwaye, Dec.).
 Notes: Ott (2009) transferred five freshwater species from India with an acrochaetioid morphology (Acrochaetium parva, A. godwardense, A. indica, A. keralayensis and A. sarmaii) to Pseudochantransia making new combinations. Pending further critical studies, we prefer to include these five species in a broad sense (i.e., bluish and/or reddish coloured with single or multiple plastids with or without pyrenoids in each cell and with or without asexual/sexual reproduction) under a single genus Audouinella.

Book reviews and reviewing--Evaluation

description: Book reviews are one of the tools that librarians use for readers' advisory. Reviews describe the contents of books and place the works into larger literary contexts through comparisons to other works and other authors. Being able to find similar authors and books is a fundamental yet challenging aspect of readers' advisory, and literary comparisons in book reviews play an important part in this process. This paper is a content analysis from a readers' advisory perspective of the number and type of literary comparisons in library and book trade periodicals. A total of 400 fiction book reviews were gathered for the study from Booklist, Library Journal, Kirkus Reviews, and Publishers Weekly. Library Journal and Booklist were found to include the highest percentage of non-neutral comparisons to other works and other authors. It is the recommendation of the study that all of the periodicals should include more non-neutral literary comparisons. This study is valuable to librarians, who consult and write reviews, and to vendors of electronic readers' advisory databases that include full-text book reviews.

description: By breaking the time-reversal-symmetry in three-dimensional topological insulators with introduction of spontaneous magnetization or application of magnetic field, the surface states become gapped, leading to quantum anomalous Hall effect or quantum Hall effect, when the chemical potential locates inside the gap. Further breaking of inversion symmetry is possible by employing magnetic topological insulator heterostructures that host nondegenerate top and bottom surface states. Here, we demonstrate the tailored-material approach for the realization of robust quantum Hall states in the bilayer system, in which the cooperative or cancelling combination of the anomalous and ordinary Hall responses from the respective magnetic and non-magnetic layers is exemplified. The appearance of quantum Hall states at filling factor 0 and +1 can be understood by the relationship of energy band diagrams for the two independent surface states. The designable heterostructures of magnetic topological insulator may explore a new arena for intriguing topological transport and functionality.
Auslegung des Laserstrahltransports und Charakterisierung des Photoinjektorlasers an FLUTE = Design of the Laser Transport System and Characterization of the Photoinjector Laser at FLUTE

description: Das Ferninfrarot Linac- und Testexperiment (FLUTE) wird zur Zeit am KIT aufgebaut. Ein Hauptziel des Linearbeschleunigers ist es ultra-kurze (< 10 fs) Elektronenpakete zur Generierung von THz-Strahlung zu erzeugen. Die Elektronenpakete werden durch den photoelektrischen Effekt, bei dem UV Laserpulse auf eine Kupferkathode treffen, ausgelöst. Die Qualität des Laserspots ist dabei maßgebend für die erreichbare Qualität des Elektronenpaktes und wird durch eine Transportoptik vorgegeben. Für den Transport des Laserstrahls vom Laserlabor bis zur Kathode über ca. 30 m, wurde im Rahmen der vorliegenden Arbeit über ein Raytracing-Programm die Transportoptik für sowohl die normalen Betriebsmodi als auch für den Extremfall des Split Ring Resonator (SRR)-Experimentes simuliert und ausgelegt. Zur weiteren Optimierung werden die tatsächlichen Strahlparameter des Laserstrahls benötigt, da diese einen großen Einfluss auf die Auslegung des Transportsystems und somit auf die Qualität der Elektronenpakete haben. Im zweiten Teil dieser Arbeit wurde für die Messung dieser Parameter ein sogenanntes Knife-Edge Experiment aufgebaut und konnte erfolgreich an einem sichtbaren Justierlaser getestet werden. Die Messung wurde anschließend am FLUTE Lasersystem aufgebaut und angepasst, so dass eine Messmethode zur Verfügung steht, mit der die Parameter der verbleibenden Laserausgänge bestimmt werden können. i

description: In this paper, we study the notion of chordality and cycles in hypergraphs from a commutative algebraic point of view. The corresponding concept of chordality in commutative algebra is having a linear resolution. However, there is no unified definition for cycle or chordality in hypergraphs in the literature, so we consider several generalizations of these notions and study their algebraic interpretations. In particular, we investigate the relationship between chordality and having linear quotients in some classes of hypergraphs. Also we show that if $\mathcal{C}$ is a hypergraph such that $\langle \mathcal{C} \rangle$ is a vertex decomposable simplicial complex or $I(\bar{\mathcal{C}})$ is squarefree stable, then $\mathcal{C}$ is chordal according to one of the most promising definitions.

Strategic fit

description: The configuration of global production networks is influenced by numerous tangibles (e.g. wage and transportation costs) as well as intangibles (e.g. employee qualification and political stability). However, due to the difficulty of quantifying intangibles, they are often neglected in decision-making resulting in not optimal configuration decisions. For this reason, this paper examines the role of intangibles in strategic network configuration in relation to corporate performance. 13 influencing factors are analyzed regarding their perceived relevance and consideration as well as the corporate network and competitive capabilities. The results show statistically significant relationships between intangibles and performance.

description: The combination of Dirac physics and elasticity has been explored at length in graphene where the so--called "elastic gauge fields" have given rise to an entire new field of research and applications: Straintronics. The fact that these elastic fields couple to fermions as the electromagnetic field, implies that many electromagnetic responses will have elastic counterparts not explored before. In this work we will first show that the presence of elastic gauge fields will be the rule rather than the exception in most of the topologically non--trivial materials in two and three dimensions. In particular we will extract the elastic gauge fields associated to the recently observed Weyl semimetals, the "three dimensional graphene". As it is known, quantum electrodynamics suffers from the chiral anomaly whose consequences have been recently explored in matter systems. We will show that, associated to the physics of the anomalies, and as a counterpart of the Hall conductivity, elastic materials will have a Hall viscosity in two and three dimensions with a coefficient orders of magnitude bigger than the previously studied response. The magnitude and generality of the new effect will greatly improve the chances for the experimental observation of this topological, non dissipative response.

description: Considered a great resource by many individuals, local history materials focus on life, both past and present, in a particular community. As digitization becomes more prevalent, many libraries are exploring methods to provide electronic access to their collections. Through a series of interviews, this paper analyzes how and why public libraries are choosing to digitize their local history materials.
