Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A cornerstone of AGN unification schemes is the presence of an optically and geometrically thick dust torus. It provides the obscuration to explain the difference between type 1 and type 2 AGN. We investigate the influence of the dust distribution on the Eddington limit of the torus. For smooth dust distributions, the Eddingtion limit on the dust alone is 5 orders of magnitudes below the limit for electron scattering in a fully ionized plasma, while a clumpy dust torus has an Eddington limit slightly larger than the classical one. We study the behaviour of a clumpy torus at low and high AGN luminosities. For low luminosities of the order of ~10^42 erg/s, the torus changes its characteristics and obscuration becomes insufficient. In the high luminosity regime, the clumpy torus can show a behaviour which is consistent with the "receding torus" picture. The derived luminosity-dependent fraction of type-2-objects agrees with recent observational results. Moreover, the luminosity-dependent covering factor in a clumpy torus may explain the presence of broad-line AGN with high column densities in X-rays.

The synergy of multi-agent systems and machine learning in power system applications
Creators: S. P. Nandanoori
Publisher: name: IEEE
Year: 2023

Multi-agent systems are widely adopted for the simulation of complex power systems and for distributed decision-making. How these agents are able to act in an intelligent and adaptive way is, however, dependent on the learning capabilities they have. It is, therefore, essential to explore the synergy between multi-agent systems and the most recent advances of machine learning. This panel addresses some of the most promising solutions that can be achieved through the combination of multi-agent systems and machine learning models. The panel will foster discussion on the advantages of combining multi-agent systems with machine learning and will identify gaps in this kind of synergy, which are expected to contribute to the opening of new research paths towards a more efficient and intelligent power and energy system.

Imperialism and Fascism Intertwined. A Materialist Analysis of the Games Industry and Reactionary Gamers
Creators: name: Emil, Hammar
Publisher: name: gamevironments
Year: 2020

description: This article paves way for a materialist analysis of the games industry as 21st century imperialism that is economically and culturally structured to cultivate anti-democratic norms that lead to fascist movements against those who question or seek to change the status quo. While much research has studied the politics of reactionary movements in gaming cultures, few have paid attention to the relation between the games industry as part of an imperialist economic system, the chauvinistic ideals symptomized in their cultural products, and the reactionist consumer audiences they attract and cultivate. As I argue, the economic structure of the industry as 21st century imperialism leads to perpetual anti-democratic crises that are maintained by reactionary forces that cultivate, attract, and form fascist grassroots organization. To conceptualize this dynamic, I invoke the labor aristocracy theory as suggested by Friedrich Engels and V.I. Lenin. This theory helps highlight the material basis from which consumers of digital games are bribed to become ideologically aligned with the chauvinism that the imperialist nature of the games industry is justified by. I also invoke W.E.B. Du Bois’ concept of a public and psychological wage to highlight the chauvinistic tendencies that the games industry cultivates via their products and marketing, in which the lack of democratic and equitable representation provides the reactionary consumers a sense of superiority. Together, these approaches account for the economic and cultural bases of both the games industry and its reactionary consumers. By anchoring my analysis in critical theories on imperialism and race, the article identifies the root causes of organized harassment and chauvinism in game cultures, as well as how the industry as 21st century imperialism benefits from and is protected by these forces of reaction.

Intelligent Life in Cosmology

description: I shall present three arguments for the proposition that intelligent life is very rare in the universe. First, I shall summarize the consensus opinion of the founders of the Modern Synthesis (Simpson, Dobzhanski, and Mayr) that the evolution of intelligent life is exceedingly improbable. Second, I shall develop the Fermi Paradox: if they existed they'd be here. Third, I shall show that if intelligent life were too common, it would use up all available resources and die out. But I shall show that the quantum mechanical principle of unitarity (actually a form of teleology!) requires intelligent life to survive to the end of time. Finally, I shall argue that, if the universe is indeed accelerating, then survival to the end of time requires that intelligent life, though rare, to have evolved several times in the visible universe. I shall argue that the acceleration is a consequence of the excess of matter over antimatter in the universe. I shall suggest experiments to test these claims.

description: We present an exhaustive study of Andreev crystals (ACs) -- quasi-one-dimensional superconducting wires with a periodic distribution of magnetic regions. The exchange field in these regions is assumed to be much smaller than the Fermi energy. Hence, the transport through the magnetic region can be described within the quasiclassical approximation. In the first part of the paper, by assuming that the separation between the magnetic regions is larger than the coherence length, we derive the effective nearest-neighbour tight-binding equations for ACs with a helical magnetic configuration. The spectrum within the gap of the host superconductor shows a pair of energy-symmetric bands. By increasing the strength of the magnetic impurities in ferromagnetic ACs, these bands cross without interacting. However, in any other helical configuration, there is a value of the magnetic strength at which the bands touch each other, forming a Dirac point. Further increase of the magnetic strength leads to a system with an inverted gap. We study junctions between ACs with inverted spectrum and show that junctions between (anti)ferromagnetic ACs (always) never exhibit bound states at the interface. In the second part, we extend our analysis beyond the nearest-neighbour approximation by solving the Eilenberger equation for infinite and junctions between semi-infinite ACs with collinear magnetization. From the obtained quasiclassical Green functions, we compute the local density of states and the local spin polarization in anti- and ferromagnetic ACs. We show that these junctions may exhibit bound states at the interface and fractionalization of the surface spin polarization.

Videogames about Politics as States of Exception
Creators: name: Yu, Hao
Publisher: name: gamevironments
Year: 2020

description: This article looks at videogames about politics within the theoretical framework of Giorgio Agamben’s states of exception and argues that while videogames can reveal political issues by implementing rules into the gameplay, they simultaneously render the in-game rules and consequences inoperative in regard to real-world politics, which can be described as states of exception in Agamben’s sense. Agamben distinguishes between the fictitious and the real state of exception, and this distinction leads to his proposal of a politics of pure means in which he considers play as a means of profanation that renders what has been played with inoperative and free. Drawing on this discussion, the article looks at the parallel between the rules in videogames and the laws in states of exception and re-examines the concepts of game rules and play under the rubric of Agamben’s political philosophy. In so doing, it explores how playing with rules in videogames about politics can turn these games into states of exception to talk about and reflect on various political issues.

description: We derive masses and radii for both components in the single-lined eclipsing binary HAT-TR-205-013, which consists of a F7V primary and a late M-dwarf secondary. The system's period is short, $P=2.230736 \pm 0.000010$ days, with an orbit indistinguishable from circular, $e=0.012 \pm 0.021$. We demonstrate generally that the surface gravity of the secondary star in a single-lined binary undergoing total eclipses can be derived from characteristics of the light curve and spectroscopic orbit. This constrains the secondary to a unique line in the mass-radius diagram with $M/R^2$ = constant. For HAT-TR-205-013, we assume the orbit has been tidally circularized, and that the primary's rotation has been synchronized and aligned with the orbital axis. Our observed line broadening, $V_{\rm rot} \sin i_{\rm rot} = 28.9 \pm 1.0$ \kms, gives a primary radius of $R_{\rm A} = 1.28 \pm 0.04$ \rsun. Our light curve analysis leads to the radius of the secondary, $R_{\rm B} = 0.167 \pm 0.006$ \rsun, and the semimajor axis of the orbit, $a = 7.54 \pm 0.30 \rsun = 0.0351 \pm 0.0014$ AU. Our single-lined spectroscopic orbit and the semimajor axis then yield the individual masses, $M_{\rm B} = 0.124 \pm 0.010$ \msun and $M_{\rm A} = 1.04 \pm 0.13$ \msun. Our result for HAT-TR-205-013 B lies above the theoretical mass-radius models from the Lyon group, consistent with results from double-lined eclipsing binaries. The method we describe offers the opportunity to study the very low end of the stellar mass-radius relation.

description: We propose and demonstrate a coherent control scheme for stable phase locking of squeezed vacuum fields. We focus on sideband fields at frequencies from 10Hz to 10kHz which is a frequency regime of particular interest in gravitational wave detection and for which conventional control schemes have failed so far. A vacuum field with broadband squeezing covering this entire band was produced using optical parametric oscillation and characterized with balanced homodyne detection. The system was stably controlled over long periods utilizing two coherent but frequency shifted control fields. In order to demonstrate the performance of our setup the squeezed field was used for a nonclassical sensitivity improvement of a Michelson interferometer at audio frequencies.

description: There is limited knowledge about the impact of climatic conditions and fruit morphological traits on the nutritional composition of the guava fruit. Fruits were gathered from 128 guava trees across four geographically diverse regions of Kenya. The fruits were morphologically characterized and analysed for their chemical and mineral composition. The ascorbic acid content correlated positively only with total annual precipitation, while total soluble solids (TSS) correlated positively with mean annual temperature. TSS correlated negatively with pulp weight and was higher in white-fleshed fruits than in the red-fleshed types. The mineral content of the fruits correlated negatively with most of the fruit weight- and size-based morphological
traits, as well as with the total annual precipitation, but positively with fruit seed proportion. This information could act as a guide in the selection of specific regions for upscaling guava production and aid in the selection of accessions for improvement programmes that enhance guava fruit nutritional composition.

description: The plants described in this review are a source of natural highintensity sweeteners, which can be used in food and by the pharmaceutical industry in the future. Most of the plants are still not approved for use, even though they are traditionally used in countries where they appear naturally. Ten of the herein described intense sweeteners are characterized by a much higher sweetness in relation to sucrose. The highest values were received for miraculin, obtained from Synsepalum dulcificum (400,000 times sweeter than sucrose, induced by citric acid); thaumatin (1,600 to 3,000 times sweeter), monatin (1,200 - 3,000) and pentadin (500 to 2,000 times sweeter). Some of these substances can also modify the taste, like changing sour into sweet taste (miraculin and neoculin). The most widely used sweeteners are steviol glycosides and thaumatin, which have been admitted for use as a sweetener in the European Union, while in the US, they have the GRAS status (thaumatin as a food enhancer). Mogroside obtained from Siraitia grosvenorii (called Luo Han Guo) is not approved for use in the EU, but was granted GRAS status in the US by the FDA. This gives a chance that it will soon be approved as a novel food or food additive in the European Union.

It is shown that the cross sections for the $E1$ and $E2$ transitions are larger at lower energies, much less than 10 MeV/nucleon. Retardation effects and Coulomb distortion are found to be both relevant for energies as low as 10 MeV/nucleon and as high as 500 MeV/nucleon. Implications for studies at radioactive beam facilities are discussed.

Turning Votes into Victory Points. Politics in Modern Board Games

description: Board games are gaining in popularity as well as sophistication on a thematic and mechanical level. We need to understand the role of this medium within our culture at large, especially in areas where board games interact with fundamental cultural values like the idea of democracy. To further this understanding, I will apply Ian Bogost’s concept of procedural expression to board games and analyze two examples that allow me to cover a wide range of phenomena: Karl-Heinz Schmiel’s Die Macher, first published in 1986, and T. L. Simons’ Bloc by Bloc: The Insurrection Game, first published in 2016. The analysis will demonstrate how a game can represent its political theme on various levels and achieve a conflicting or a coherent political message. The example of Bloc by Bloc will prove that board games are capable of expressing very nuanced political positions and stimulating a critical reflection of our political culture and even the role that board games might play in it.

Likers Get Liked. Platform Capitalism and the Precariat in Death Stranding
Creators: name: Ryan, House
Publisher: name: gamevironments
Year: 2020

description: Kojima Productions’ Death Stranding (2019) imagines a post-apocalyptic future in which the United States has been broken apart into isolated, individualist communities. Players assume the role of Sam Bridges, a courier for the seemingly ubiquitous Bridges corporation, who is tasked with reunifying the country by linking the cloistered settlements to the Chiral Network, allowing communication and the sharing of resources between those connected to it. In Death Stranding, the themes of control and precariousness resonate through both semiotics and procedure. Bridges, as a symbol for the game’s procedural mechanics, asks players to make connections between what Sam is asked to do (by Bridges) and what they are asked to do (by the videogame). Drawing parallels between Bridges and platform capitalism, this paper will examine Death Stranding as an allegorithm, in Alexander Galloway’s terms, to reveal how the game replicates the real world systems of precarization of an emerging class of workers: the precariat. This paper argues that Death Stranding becomes a ritualization of precarious labor and that the playful disposition it engenders provides a starting place to begin reassessing our modes of democratic participation.

Optimum life of production assets in short and medium term timber harvesting projects
Creators: name: Oyugi Ogweno, Donald C.
Publisher: name: University of British Columbia
Year: 2010

description: An optimal equipment replacement model was developed, that is useful for evaluating machinery replacement proposals. The model is based on discounted cash flow methods, and performs the evaluation by comparing the cash flow profile of the currently owned machine (the "defender") against that of a proposed replacement (the "challenger") over a finite time period. The optimum time to replace the defender is determined as the age which will maximize the net revenues from operating both machines over the planning horizon. Real time data were collected from the operation of similar machines, and used to estimate repair and maintenance costs, machine resale values, and machine operating costs. These costs were then discounted to a base year, and aggregated into cash flow profiles. The cash flow profiles were then converted to annual equivalents, which form the basis of the replacement decision. A method of estimating the rate at which a group of machines accumulate technological obsolescence was developed. These estimates are made as a function of the improved ratio of productivity to fuel consumption of new generations of machines over older ones. The replacement model was encoded into a microcomputer spreadsheet application program, that is useful as a financial planning tool in short and medium term timber harvesting projects. The program is interactive, and can be used to evaluate the sensitivity of the proposed replacement to different economic parameters. Sensitivity analyses was performed on the computer model by varying six of the input variables. From the results, it was concluded that the optimum life was relatively insensitivity to changes in most of the inputs. The cash flows, however, was highly sensitive to changes in most of the input variables. Changes in the length of the planning horizon had the highest effect on both optimum life and cash flows of the assets. The value added cost of the product had no effect on optimum life, but a very high effect on cash flows.
The Missing Memorial: The Division 2 and the Politics of Memory

description: The Division 2 (2019) presents players with a near one-to-one recreation of Washington, D.C. with a glaring omission: The Vietnam Veterans Memorial. How does the erasure of the Vietnam Veterans Memorial reflect the politics of an apolitical approach to game design? What does the playable spectacle of military action but erasure of the remembrance of lives lost say about the politics of environmental design? The following details the development of The Division 2 and the controversies that surrounded it following the critiques of The Division and the developer’s insistence on the apolitical nature of their entertainment product. Utilizing Avery Gordon’s theory of hauntings, I apply an ethnographic approach to the digital recreation of the D.C. landscape to explore the creative and technical decisions developer Massive Entertainment made in their creation of D.C. to examine the significance of the Vietnam Veterans Memorial’s absence in The Division 2. I analyze what the claims to apolitical creation mean in the context of an explicitly ideological game set in the Tom Clancy universe and how this reflects the ways power operates through video games as a means of enforcing American exceptionalism and techno-military fetishism to the detriment of contemporary democratic values in the United States.

The Face of Authority through Sid Meier's Civilization Series

Year: 2020

description: The turn-based strategy videogame genre tends to emphasize the military elements in detriment of other aspects. That is not the case in Sid Meier's Civilization series (1991-2016). Players are welcomed to focus on other aspects of society such as science, culture, diplomacy and economy, to the point of becoming a viable path to endgame victory themselves, though far more difficult. Narratively speaking, Civilization allows the player to explore different human societies across the species' history. In this paper, we want to place our focus on the authoritarian options the game provides and how they operate under a clear 19th Century cultural evolutionary framework. Civilizations are measured in different stages according to their development allowing choices such as type of government, technological advance or religion. The series shows the adoption of a functionalist thought pattern as authoritarian options do not carry a penalty worse than more liberal or progressive ones. While in the first installments of the game there was a clear bias towards liberal democracy and open society, that bias has been consistently blurred in more recent installments (now currently in the sixth game of the series) showing a certain degree of amorality in the exercise of power, thus giving us a window to analyze the changes in the power discourse.

Play America Great Again. Manifestations of Americanness in Cold War Themed Video Games
Creators: name: Regina, Seiwald
Publisher: name: gamevironments
Year: 2020

description: This study analyses mechanisms through which Cold War themed video games played from an American perspective propagate US authoritarianism by reiterating concepts of Americanness generated in popular media during the Cold War era. These video games work with cultural, historical, and social stereotypes to generate a dichotomy between good and evil and they heavily rely on emotions and morality in their portrayal of communist, socialist, and Soviet enemy forces. Popular concepts associated with America are used to propagate democracy and (political) freedom, while simultaneously vilifying their adversaries. Through drawing parallels to American Cold War propaganda and its utilisation of popular media, this paper asks how stereotypical notions of America are generated through symbolism in an engagement with material objects as well as thoughts and beliefs. Topics engaged with are media control, free speech, programming, espionage, intrigues, paranoia, trust, and the morality of the individual in a hyperreal environment. This study is conducted in reference to Operation Flashpoint: Cold War Crisis (2001), Freedom Fighters (2003), Call of Duty: Black Ops (2010), Tom Clancy’s Splinter Cell: Conviction (2010), Homefront (2011), and Alekhine’s Gun (2016). By considering mechanisms of propaganda in these games, it is shown how manifestations of Americanness are generated in them and how they affect friend and foe images.

For the first time we experimentally prove the compatibility of especially the latter two. To achieve a broadband non-classical sensitivity improvement we applied a filter cavity for compensation of quadrature rotation. Signal to noise ratio was improved by up to 2.8 dB beyond the coherent state's shot noise. The complete set-up was stably locked for arbitrary times and characterized by injected single-sideband modulation fields.

Grid decarbonization efforts have resulted in accelerated adoption of renewable energy resources by utilities worldwide as well as rapid electrification of end-use loads. Adoption of variable resources as well as new load components like electric vehicles have increased the uncertainty on both the resource and the demand side that planners must consider for investing in new infrastructure as well as capacity to ensure reliable system operation. For making optimal expansion plans around capacity, transmission and distribution infrastructure, integrated system planning with coordinate reliability assessment across generation (G), transmission (T) and distribution (D) is becoming indispensable. However, such integrated planning ensuring composite system reliability across G, T and D can be challenging and requires improvements to the present tools and analyses. The aim of this panel is to discuss challenges as well as new developments around composite system reliability to accelerate grid decarbonization efforts.

Discrepancy Detected. Operationalizing Immigration and Borderzone Policy in Papers, Please
Creators: name: David, Kocik
Publisher: name: gamevironments
Year: 2020

description: This article examines how Papers, Please (2013) critiques modern immigration policies by operationalizing immigration law and borderzone security. In the game, the player is an immigration officer at a recently demilitarized zone between two fictionalized countries. Every in-game day, the player decides which migrants must be admitted, rejected, or detained by comparing increasingly complicated documentation to ever-changing immigration policies. Through a visual and operational emphasis on rules and paperwork, Papers, Please conveys how supposedly fair immigration processes prioritize documentation and order over the lives and rights of individual immigrants. The game also shows how modern governments implement haphazard and reactionary immigration policies through ever-changing rules for the player to follow. By making the player complicit in the systemization of immigration, the game shows how seemingly equitable borderzone policies support daily unethical and dehumanizing treatment of migrants at highly regulated borders.

On-line Viterbi Algorithm and Its Relationship to Random Walks

description: In this paper, we introduce the on-line Viterbi algorithm for decoding hidden Markov models (HMMs) in much smaller than linear space. Our analysis on two-state HMMs suggests that the expected maximum memory used to decode sequence of length $n$ with $m$-state HMM can be as low as $Θ(m\log n)$, without a significant slow-down compared to the classical Viterbi algorithm. Classical Viterbi algorithm requires $O(mn)$ space, which is impractical for analysis of long DNA sequences (such as complete human genome chromosomes) and for continuous data streams. We also experimentally demonstrate the performance of the on-line Viterbi algorithm on a simple HMM for gene finding on both simulated and real DNA sequences.
Democracy Dies playfully. Three Questions – Introductory Thoughts on the Papers Assembled and Beyond
Creators: name: Eugen, Pfister
name: Tobias, Winnerling

Publisher: name: gamevironments
Year: 2020

description: In this introduction to the special issue, we trace the digital game’s potential to represent (un)democratic political systems. We pose three central questions: Is the digital game an undemocratic medium? Is digital game development undemocratic? And: Are digital game communities undemocratic? By answering these three questions, we engage with the implications of different digital game’s narratives and game mechanics, with common concerns about working conditions in game development as well as with group dynamics in game communities. In every section, the contributions to this special issue are presented and linked to these overarching themes.

Wir sind das Volk! Agitprop between East and West Germany
Creators: name: Anton, Oehmsen-Clark
Publisher: name: gamevironments
Year: 2020

description: Wir Sind Das Volk! (2014) gamifies the conflict between East and West Germany by having players compete to undermine the real or perceived living standards of their respective opponents. The possibility of an Eastern Bloc extending well beyond the fall of the Berlin Wall is a very real possibility in this game world. The recognition of this historical contingency allows Wir Sind Das Volk! to forward a model of gameplay that sees the player encounter how democracies, like Soviet republics, rely on a complex network of agitprop symbolism. Wir Sind Das Volk! mixes many of board gaming’s traditional gameplay conventions, and in doing so asks the player to participate in making alternative chronologies of the Cold War.

Single particle entanglement in the mid-and ultra-relativistic regime
Creators: name: Ondra, M.
name: Hiesmayr, B. C.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this work we analyze the amount of entanglement associated with the spin and momentum degrees of freedom of a single massive spin-$\frac{1}{2}$ particle from a relativistic perspective. The effect of a Lorentz boost introduces a Wigner rotation that correlates the spin and momentum degrees of freedom. We show that the natural basis to discuss the geometrical effects of the boost are the helicity eigenstates in the rest frame. In the mid-relativistic regime (where the Wigner rotation angle is limited by $δ< \fracπ{2}$) we prove for states with equal helicity that the entanglement with respect to the Wigner rotation angle is monotonically decreasing, however, in the ultra-relativistic regime ($δ> \fracπ{2}$) the entanglement is increasing. If the states are prepared as a superposition of unequal helicity eigenstates, the monotonic behaviour is inverted. This implies that in the ultra-relativistic regime a geometrical setup can be found such that the amount of entanglement exhibits local maxima or minima. This shows a counter-intuitive behaviour of the relative amount of entanglement, an effect due to the internal and external geometrical configuration space, and points towards the difficulties in achieving a Lorentz invariant formulation of entanglement in general.

Code of Resistance. On the Potential of Digital Games and Game Jams for Civic Education
Creators: name: Michael, Laumer
name: Marcel, Kabaum
Publisher: name: gamevironments
Year: 2020

description: Some digital games deal with politics and democracy and are appropriate for civic education. Schools that want to include these games in their curriculum do not have to rely on commercial products alone, but can also use other easily available games and simple tools. Often these are even created by young people in game jams. Five freely available games from the game jam #ResistJam in 2017 will be examined for civic gaming experiences and their political content using didactic models, to discuss their possible integration into the classroom.

description: Cyber-Physical Systems (CPS) provide enormous potential for innovation but a precondition for this is that the issue of dependability has been addressed. This paper presents the concept of a Digital Dependability Identity (DDI) of a component or system as foundation for assuring the dependability of CPS. A DDI is an analyzable and potentially executable model of information about the dependability of a component or system. We argue that DDIs must fulfill a number of properties including being universally useful across supply chains, enabling off-line certification of systems where possible, and providing capabilities for in-field certification of safety of CPS. In this paper, we focus on system safety as one integral part of dependability and as a practical demonstration of the concept, we present an initial implementation of DDIs in the form of Conditional Safety Certificates (also known as ConSerts). We explain ConSerts and their practical operationalization based on an illustrative example.
At the Edge of Utopia. Esports, Neoliberalism and the Gamer Culture’s Descent into Madness

description: This article discusses the controversy regarding Brazilian Senate Bill No. 383, which deals with the regulation of esports activity in the country. We analyzed the conversation about the hashtag #TodosContraPLS383, a repudiation movement organized on Twitter in November 2019, to engender an argument that criticizes (1) the relations between the games industry and its practices of governance and (2) how individuals assimilate neoliberal discourse within this culture. From an ethnomethodological approach and through qualitative analysis that employs ATLAS.ti to collect and make sense of the data, we reconstruct a narrative that debates anti-regulation rhetoric, exposing gamer culture's relationship with neoliberal ideology.
