description: Using standard nuclear magnetic resonance (NMR) technique and a well-fabricated sample, we have succeeded in directly observing local magnetic field generated by a micro-magnet Ni45Fe55 (the thickness of 400-nm) which was sputtered on an Al layer of 20-nm thickness. Improved sensitivity of our NMR technique enabled us to clearly observe Al-NMR signals, which are confirmed to come from Al nuclei in the 20-nm layers. From the analysis of the Al-NMR spectra, the local magnetic field was found to be +0.17+-0.02 (-0.20+-0.01) Tesla, the sign of which is consistent with the geometry that the external magnetic field was applied perpendicular (parallel) to the Al layer. The present study gives a potential key element toward realizing higher resolution in magnetic resonance imaging (MRI).

description: Highly polarized mixtures of atomic Fermi gases constitute a novel Fermi liquid. We demonstrate how information on thermodynamic properties may be used to calculate quasiparticle scattering amplitudes even when the interaction is resonant and apply the results to evaluate the damping of the spin dipole mode. We estimate that under current experimental conditions, the mode would be intermediate between the hydrodynamic and collisionless limits.

description: This presentation for the AIES 21 doctoral consortium examines the Latin American crowdsourcing market through a decolonial lens. This research is based on the analysis of the web traffic of ninety-three platforms, interviews with Venezuelan data workers of four platforms, and the analysis of the documentation issued by these organizations. The findings show that (1) centuries-old global divisions of labor persist, in this case, with requesters located in advanced economies and workers in the Global South. (2) That the platforms' configuration of the labor process constrains the agency of these workers when producing annotations. And, (3) that ideologies originating from the Global North serve to legitimize and reinforce this global labor market configuration.

 Distribution. BRAZIL (new record): Bahia: Ilhéus; DOMINICA: Clarke Hall; COLOMBIA: Magdalena: PNN Tayrona, Zaino, COSTA RICA. (Plowes et al. 2009). This record is the first out of the Central America and Caribbean distribution of this species (Dominican, Costa Rica and Magdalena in Colombia).
 Remarks. The collected specimens have the distal process of the female with rounded sides, slightly different to descriptions made by Plowes et al. (2009) of the species. We consider that this slightly morphological difference is not sufficient to describe a new species. This disjunct distribution may be occurring by the lack of intermediate data collections, as seen in Pseudacteon fowleri and P. pradei (Patrock 2010). It is possible that this parasitoid species presents the same geographical distribution of the host Solenopsis geminata proposed by Ross et al. (2009).
 Field observations. The specimens were collected associated with a colony of Solenopsis geminata.

description: We study the dynamics of initial nucleation processes of photoinduced structural change of molecular crystals. In order to describe the nonadiabatic transition in each molecule, we employ a model of localized electrons coupled with a fully quantized phonon mode, and the time-dependent Schrödinger equation for the model is numerically solved. We found a minimal model to describe the nucleation induced by injection of an excited state of a single molecule in which multiple types of intermolecular interactions are required. In this model coherently driven molecular distortion plays an important role in the successive conversion of electronic states which leads to photoinduced cooperative phenomena.

Carrier settlement and subsistence in the Chinlac/Cluculz Lake area of Central British Columbia
Creators: name: Cranny, Michael William
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines Carrier settlement and subsistence patterns within a study area near the confluence of the Stuart and Nechako Rivers, and around Cluculz and Cobb lakes. The Carrier site at Chinlac, excavated by Charles Borden in 1950 and 1952, is important to this study and is re-examined in terms of hypothetical models which are developed to explain settlement and subsistence in the late prehistoric period, the protohistoric period, and the early historic period. In particular, a settlement system is proposed for the protohistoric period in which there are two major elements, or locations where settlement occurred, and these are at the confluence of the Stuart and Nechako Rivers and on the north shore of Cluculz lake near the outflow. In the former location, salmon were harvested, and in the latter, lake resources were harvested. The salmon procurement sites were occupied from July to November, and the lakeside locations were used for the rest of the year by the same group of people. A smaller population, different exploitive technology, and smaller archaeological sites are predicted for the late prehistoric and historic periods. The models proposed in this thesis are based on environmental, ethnographic, and historical research. In the case of the latter, the original fur traders' accounts from Fort St. James and Fort Fraser were consulted and the information used to determine changes in settlement and subsistence over time. In general, the study adhered to the direct historic approach tempered with a cultural ecological perspective. In order to verify the proposals made in the thesis, the materials and records of Borden's Chinlac excavation were re-examined, and an archaeological survey of the study area was conducted. The data tend to support the hypotheses put forward but not all could be fully tested. Artifacts from the Chinlac site confirmed that the site was occupied during the protohistoric period, and faunal remains, house type, and other indicators make a summer/ fall occupation of the site probable. Archaeological survey found 37 archaeological sites grouped in several areas. The relatively larger sites were located either at the confluence of the rivers (at and near Chinlac) or at the outflow of Cluculz Lake. Smaller sites were scattered along the north shore of the lake, along the river banks, and elsewhere. On the basis of this data, it is concluded that the two element ( binary) settlement system is appropriate for the protohistoric period.

description: We consider the local model of a Shimura variety of PEL type, with the unitary similitudes corresponding to a ramified quadratic extension of $\mathbb{Q}_p$ as defining group. We examine the cases where the level structure at $p$ is given by a parahoric that is the stabilizer of a selfdual periodic lattice chain and that is special in the sense of Bruhat--Tits theory. We prove that in these cases the special fiber of the local model is irreducible and generically reduced; consequently, the special fiber is reduced and is normal, Frobenius split, and with only rational singularities. In addition, we show that in these cases the local model contains an open subset that is isomorphic to affine space.

description: We study the spectrum of the even parity excitations of the nucleon in quenched lattice QCD. We extend our earlier analysis by including an expanded basis of nucleon interpolating fields, increasing the physical size of the lattice, including more configurations to enhance statistics and probing closer to the chiral limit. With a review of world lattice data, we conclude that there is little evidence of the Roper resonance in quenched lattice QCD.

Do We Expect More from Radiology AI than from Radiologists?
Creators: name: Mazurowski, Maciej A.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Computers and Society (cs.CY)
subject: FOS: Computer and information sciences

description: What we expect from radiology AI algorithms will shape the selection and implementation of AI in the radiologic practice. In this paper I consider prevailing expectations of AI and compare them to expectations that we have of human readers. I observe that the expectations from AI and radiologists are fundamentally different. The expectations of AI are based on a strong and justified mistrust about the way that AI makes decisions. Because AI decisions are not well understood, it is difficult to know how the algorithms will behave in new, unexpected situations. However, this mistrust is not mirrored in our expectations of human readers. Despite well-proven idiosyncrasies and biases in human decision making, we take comfort from the assumption that others make decisions in a way as we do, and we trust our own decision making. Despite poor ability to explain decision making processes in humans, we accept explanations of decisions given by other humans. Because the goal of radiology is the most accurate radiologic interpretation, our expectations of radiologists and AI should be similar, and both should reflect a healthy mistrust of complicated and partially opaque decision processes undergoing in computer algorithms and human brains. This is generally not the case now.

description: We study the firms’ choice of whether or not to consider pieces of information concerning their interdependence. In particular, any firm can strategically choose to consider or not the fact that industry output is affected by its own production choice. If this piece of information is considered, the firm behaves as an aligopolist; if not,
firm behaves in a monopolistically competitive way. Thus, the market regime is endogenously determined. We show that different outcomes can emerge, depending on the number of firms, the degree of product substitutability and the cost structure.

description: We show that if $Z$ is "homogeneously multifractal" (in a sense we precisely define), then $Z$ is the composition of a monofractal function $g$ with a time subordinator $f$ (i.e. $f$ is the integral of a positive Borel measure supported by $\zu$). When the initial function $Z$ is given, the monofractality exponent of the associated function $g$ is uniquely determined. We study in details a classical example of multifractal functions $Z$, for which we exhibit the associated functions $g$ and $f$. This provides new insights into the understanding of multifractal behaviors of functions.

description: The interest of quadratic algebras for position-dependent mass Schrödinger equations is highlighted by constructing spectrum generating algebras for a class of d-dimensional radial harmonic oscillators with $d \ge 2$ and a specific mass choice depending on some positive parameter $α$. Via some minor changes, the one-dimensional oscillator on the line with the same kind of mass is included in this class. The existence of a single unitary irreducible representation belonging to the positive-discrete series type for $d \ge 2$ and of two of them for d=1 is proved. The transition to the constant-mass limit $α\to 0$ is studied and deformed su(1,1) generators are constructed. These operators are finally used to generate all the bound-state wavefunctions by an algebraic procedure.

Application of the Weyl-Wigner formalism of noncommutative geometry
Creators: name: Zampini, Alessandro
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2005

description: In this dissertation the Weyl-Wigner approach is presented as a map between funcions on a real cartesian sympletic vector space and a set of operators on a Hilbert space, to analyse some aspects of the relations between quantum and classical formalism, both as a quantization, and as a classical limit.
It is presented an extension of this formalism to the case of a more general classical phase space, namely one whose configuration space is a compact simple Lie group.
In the second part, it is used to develop a fuzzy approximation to the algebra of functions on a disc. This is the first example of a fuzzy space originating from a classical space which has a boundary. It is analysed how this approximation copes the presence of ultraviolet divergences even in noninteracting field theories on a disc.
Molecular dynamics of triglycerides: atomistic and coarse-grained approaches
Creators: name: Brasiello, Antonio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: The objective of this thesis have been the development and the analysis of microscopic mathematical models to investigate the dependence of triglycerides conformations from environmental conditions. Triglycerides are important constituents of food products that show polymorphic solid transitions. Such behaviors influence greatly processes management involving fats mixtures. To investigate the relationship between macroscopic conditions and conformational induced properties, we dealt with microscopic mathematical models.
The first part of the thesis regards the building of a united-atoms model from which physical properties and structural distribution functions of a liquid phase were derived.
The second part regards the development of a coarse-grained model. The force field of such model was developed, by means of statistical tools, using
suitable distribution functions derived from the atomistic one.
The coarse-grained model was used to perform numerical experiments to highlight the dependence of molecules conformations from experimental conditions.
The results of our simulations show a clear relationship between the conformational state of molecules and temperature annealing condition. Moreover, the improvement of order features through radial distribution functions was
pointed out during several heating-cooling processes. The formation of small clusters of few planar molecules can be easily observed by means of visual inspection.
The effect of simple flow conditions imposed on the system was also investigated. Imposed flows increase molecules mobility causing a raise of planar molecules and a greater uniform distribution of inter-molecular orientational
order vector.

description: We study the asymptotic behavior of the spectrum of a quantum system which is a perturbation of a spherically symmetric anharmonic oscillator in dimension 2. We prove that a large part of its eigenvalues can be obtained by Bohr-Sommerfeld quantization rule applied to the normal form Hamiltonian and also admit an asymptotic expansion at infinity. The proof is based on the generalization to the present context of the normal form approach developed in [BLM20b] (see also [PS10]) for the particular case of $T^d$.
Determination of the effects of fish size and feed pellet size on the settling characteristics of Rainbow trout (Salmo gairdneri) culture cleaning wastes

Publisher: name: University of British Columbia
Year: 2010

description: This research reports on the determination of the effects of fish size and feed pellet size on the settling characteristics of Rainbow trout (Salmo gairdneri) culture, tank cleaning wastes. Flocculant particle settling curves (Type II) were developed from settling column analysis of cleaning wastes from 11-311 gram Rainbow trout fed a moist pellet diet (Oregon Moist Pellet ®). Four feed pellet sizes were investigated: 3/32, 1/8, 5/32 and 3/16 inch. Overall non-filterable residue removal curves and individual particle settling velocity distribution curves, derived from the Type II settling curve of each fish size and feed pellet size group, were compared. Slopes and y-intercepts of the linearized overall non-filterable residue removal curves and individual particle settling velocity distribution curves were compared using the Equality of Slope Test (S:SLTEST). Results of the test for a common regression equation indicated there were no significant differences in the proportional distribution of particle sizes within the cleaning wastes. Variations observed in the initial rates of removal within the overall non-filterable residue removal curves were considered insignificant Settling trials were pooled in order to obtain single curves, characterizing the overall solids removal rate and the individual particle settling velocity distribution of the waste solids.

description: In recent years, we have witnessed an explosion of experimental tools by which quantum systems can be manipulated in a controlled and coherent way. One of the most important goals now is to build quantum simulators, which would open up the possibility of exciting experiments probing various theories in regimes that are not achievable under normal lab circumstances. Here we present a novel approach to gain detailed control on the quantum simulation of strongly correlated quantum many-body systems by constructing the explicit quantum circuits that diagonalize their dynamics. We show that the exact quantum circuits underlying some of the most relevant many-body Hamiltonians only need a finite amount of local gates. As a particularly simple instance, the full dynamics of a one-dimensional Quantum Ising model in a transverse field with four spins is shown to be reproduced using a quantum circuit of only six local gates. This opens up the possibility of experimentally producing strongly correlated states, their time evolution at zero time and even thermal superpositions at zero temperature. Our method also allows to uncover the exact circuits corresponding to models that exhibit topological order and to stabilizer states.

description: The exponential increase in publication rate of new articles is limiting access of researchers to relevant literature. This has prompted the use of text mining tools to extract key biological information. Previous studies have reported extensive modification of existing generic text processors to process biological text. However, this requirement for modification had not been examined. In this study, we have constructed Muscorian, using MontyLingua, a generic text processor. It uses a two-layered generalization-specialization paradigm previously proposed where text was generically processed to a suitable intermediate format before domain-specific data extraction techniques are applied at the specialization layer. Evaluation using a corpus and experts indicated 86-90% precision and approximately 30% recall in extracting protein-protein interactions, which was comparable to previous studies using either specialized biological text processing tools or modified existing tools. Our study had also demonstrated the flexibility of the two-layered generalization-specialization paradigm by using the same generalization layer for two specialized information extraction tasks.

description: Several diamond bulk crystals with a concentration of electrically neutral single substitutional nitrogen atoms of $\lesssim 80~$ppm, the so-called C- or P1-centres, were irradiated with electrons at 10 MeV energy and low fluence. The results show a complete suppression of the irreversible behavior in field and temperature of the magnetization below $\sim 30$~K, after a decrease of $\lesssim 40~$ppm in the concentration of C-centres produced by the electron irradiation. This result indicates that magnetic C-centres are at the origin of the large hysteretic behavior found recently in nitrogen-doped diamond crystals. This is remarkable because of the relatively low density of C-centres, stressing the extraordinary role of the C-centres in triggering those phenomena in diamond at relatively high temperatures. After annealing the samples at high temperatures in vacuum, the hysteretic behavior is partially recovered.

description: The achievement of Sustainable Development Goals (SDGs) by 2030 hinges on the intricate interplay between environmental performance and human development. This study employs Canonical Correlation Analysis (CCA) on both a global scale and within the context of South Asia, utilizing the latest Environmental Performance Index (EPI) and Human Development Index (HDI) reports from 2022. Globally, the CCA underscores that Environmental Performance significantly influences key SDGs, with metrics explaining nearly 85% of variations in Life Expectancy (SDG-3) and Per Capita Gross National Income (SDG-8.5). Education indicators, such as Expected Years of Schooling (SDG-4.3) and Mean Years of Schooling (SDG-4.4), are strongly influenced by Environmental Health, showcasing a profound connection. Interestingly, the Human Development Index demonstrates a robust correlation (92.8%) with Environmental Health but displays a less pronounced relationship (48.2%) with Ecosystem Vitality on a global scale. The findings unveil a global synergy, with composite indices exhibiting strong correlation (86%) and mutual explanatory power. However, the South Asia regional analysis presents a divergent narrative, revealing statistically insignificant insights and negative influences on environmental performance (-4.6%) and human development (-20.3%) through ecosystem vitality and mean years of schooling, respectively. This research contributes valuable insights for global progress towards SDG-2030, emphasizing the need for tailored attention and policy implementation in South Asia to attain sustainable development. The implications inform policymakers and stakeholders, advocating for integrated policies that empower education, foster inclusive economic growth, nurture health and environment synergy, bolster ecosystem resilience, and promote data-driven decision-making. Employing Canonical Correlation Analysis through statistical tools such as E-views 12, SPSS 25 and Stata 15, this study underscores the significance of fostering a harmonious relationship between nature and human development for long-term societal benefits.

description: This study of coal combustion was carried out in a half-column spout-fluid bed combustor, in which Forestberg coal, a sub-bituminous Alberta coal, was burned in inert beds of sand. The combustor consists of a half cylindrical stainless steel column of 0.152 m I. D. and 1.06 m long, a half cylindrical cone fitted with an inlet orifice of 15.9 mm and a perforated plate as distributor surrounded by a plenum chamber, and a flat stainless steel panel with quartz glass windows. Aspects studied included hydrodynamic and combustion patterns, axial and radial temperature profiles, axial oxygen concentration profiles and burnout times of coal particles. Depending on operating conditions and properties of bed materials, four different flow patterns were established: Stable spouting, pulsatory spouting, jet-in-fluidized-bed and slugging. It was found that the maximum stable spouting height decreased as the bed temperature increased. Axial temperature profiles in the spout and annulus were found to be uniform for both spouted and spout-fluid beds except for a short distance above the inlet orifice. However, a temperature increase was found in the fountain above the spout when finer coal particles were employed. Above the annulus the temperatures increased substantially. More uniform axial temperature profiles could be achieved by introducing auxiliary air to create a spout-fluid bed. Radial temperature profiles were uniform both in the annulus and in the fountain region. Axial oxygen concentration profiles were found to be closely related to the flow patterns and solids properties. When larger coal particles (1mm) were used the oxygen concentration profiles were uniform within and above the spout, but a decrease of concentration was observed when fine coal particles (0.6 mm) were used. In the annulus a sharp decline of concentration started near the bed surface, and a minimum was reached in the fountain region. Concentration profiles became more uniform when auxiliary air was introduced. Compared with data reported in literature for fluidized bed combustion, the burnout times of coal particles in spouted and spout-fluid beds were found to be significantly shorter. A model for estimating the burnout times was proposed and tested against the experimental data. For the particle size and temperature range tested, the combustion was mainly controlled by chemical reaction.

description: A scanning superconducting quantum interference device (SQUID) microscope (SSM) is used to study the magnetic imaging of dynamic motion of quantized interlayer vortices induced by the Lorentz force in anisotropic high-Tc La_(1.87)Sr_(0.13)CuO_4 single crystals. It is found that 3 modes of flux motion switch depending on the transport current. By increasing the current a transition from the creep-like behavior of vortices to a steady flow of vortices was observed. Even higher current induced a continuous expansion of vortex-flow area indicating an inhomogeneous distribution of various pinning centers.

La poli(ADP-ribosilazione) in cellule neoplastiche ed  in risposta ad agenti chemioterapici

description: Alla luce di evidenze autorevoli che suggeriscono un ruolo della reazione di poli(ADP-ribosilazione) in molti processi cellulari come il riparo del DNA e la trascrizione, la crescita cellulare e la trasformazione, la mia ricerca si è focalizzata sull’analisi dell’azione di inibitori di PARP come adiuvanti di agenti chemioterapici (es. veleni di Topo I ed interferoni) in cellule di glioblastoma e di carcinoma.
In una prima sezione  sono stati investigati gli effetti indotti dal trattamento con l’inibitore di Topo I, il topotecano (TPT) e l’inibitore di PARP, l’NU1025 in due linee cellulari di glioblastoma umano D54p53wt e U251p53mut. E’ stato trovato un effetto sinergico sia in termini di inibizione di crescita che di arresto in G2/M, mentre  NU1025 non ha mostrato alcun effetto citotossico. I risultati mostrano che TPT causa un aumento dell’attività enzimatica, dovuta soprattutto all’automodificazione di PARP-1, che è stato messo in relazione  con la stabilizzazione di p53 che a sua volta ha determinato un’overespressione di p21 nelle D54. Inoltre NU1025 in combinazione con TPT incrementa specificamente il livello nucleare di p21. Viceversa in U251 il trattamento con TPT non ha avuto conseguenze sulla forma mutata inattiva di p53. Tali evidenze sono in linea con una segnalazione ad opera di PARP-1 , via p53 e p21 del danno al DNA risultante dall’inibizione di Topo I.
In una seconda sezione della ricerca è stata analizzata la relazione tra la poli(ADP-ribosilazione) e la via  JAK/STAT di trasduzione del segnale dipendente dall’interferone- in cellule umane di carcinoma epidermoide, KB. Risultati precedi hanno mostrato che l’inibizione di crescita da IFN in KB, era accompagnata da un aumento dell’attività PARP, mentre a tempi più lunghi l’innesco dell’apoptosi era associato alla proteolisi caspasi-dipendente di PARP-1. Inoltre il trattamento combinato con un inibitore di PARP (3-ABA), revertiva l’inibizione di crescita e l’apoptosi causate dall’IFN.
Alla luce di questi risultati, che suggeriscono che PARP-1 possa essere direttamente coinvolta nell’espressione genica dipendente dall’IFN (es. STAT-1), la presente ricerca è stata indirizzata alla definizione della poli(ADP-ribosilazione) di STAT-1. Inizialmente è stata valutata l’overespressione, la fosforilazione e la traslocazione nucleare di STAT-1 dipendente da IFN. I risultati hanno mostrato che STAT-1 piuttosto che subire modificazioni covalenti e non covalenti da parte di PARP-1, è capace di interagire fisicamente con essa, come riportato per altri fattori trascrizionali.

description: The non-Debye, \textit{i.e.,} non-exponential, behavior characterizes a large plethora of dielectric relaxation phenomena. Attempts to find their theoretical explanation are dominated either by considerations rooted in the stochastic processes methodology or by the so-called \textsl{fractional dynamics} based on equations involving fractional derivatives which mimic the non-local time evolution and as such may be interpreted as describing memory effects. Using the recent results coming from the stochastic approach we link memory functions with the Laplace (characteristic) exponents of infinitely divisible probability distributions and show how to relate the latter with experimentally measurable spectral functions characterizing relaxation in the frequency domain. This enables us to incorporate phenomenological knowledge into the evolution laws. To illustrate our approach we consider the standard Havriliak-Negami and Jurlewicz-Weron-Stanislavsky models for which we derive well-defined evolution equations. Merging stochastic and fractional dynamics approaches sheds also new light on the analysis of relaxation phenomena which description needs going beyond using the single evolution pattern. We determine sufficient conditions under which such description is consistent with general requirements of our approach.

description: In this work, exact solutions of static and spherically symmetric space-times are analyzed in f(R) modified theories of gravity coupled to nonlinear electrodynamics. Firstly, we restrict the metric fields to one degree of freedom, considering the specific case of g_tt\g_rr = -1. Using the dual P formalism of nonlinear electrodynamics an exact general solution is deduced in terms of the structural function H_P. In particular, specific exact solutions to the gravitational field equations are found, confirming previous results and new pure electric field solutions are found. Secondly, motivated by the existence of regular electric fields at the center, and allowing for the case of g_tt\g_rr \= -1, new specific solutions are found. Finally, we outline alternative approaches by considering the specific case of constant curvature, followed by the analysis of a specific form for f(R).

description: We construct a gauge-mediation model with a D-term supersymmetry (SUSY) breaking. R-symmetry breaking necessary for generating the SUSY standard-model gaugino masses is given by gaugino condensation of a strongly coupled gauge theory in the hidden sector. The energy scale of the strong dynamics of the hidden sector gauge theory should be around the messenger mass scale M, or otherwise perturbative calculations would be reliable and would lead to negative soft mass squared for squarks and sleptons. Thus, all the mass scales are controlled by a virtually single parameter, \sqrt{D}/M. This model covers a very wide range of gravitino mass, m_{3/2} \simeq 1 eV--100 TeV. Possible embeddings of the model in string theory are also discussed.

Intelligence and Unambitiousness Using Algorithmic Information Theory

description: Algorithmic Information Theory has inspired intractable constructions of general intelligence (AGI), and undiscovered tractable approximations are likely feasible. Reinforcement Learning (RL), the dominant paradigm by which an agent might learn to solve arbitrary solvable problems, gives an agent a dangerous incentive: to gain arbitrary "power" in order to intervene in the provision of their own reward. We review the arguments that generally intelligent algorithmic-information-theoretic reinforcement learners such as Hutter's (2005) AIXI would seek arbitrary power, including over us. Then, using an information-theoretic exploration schedule, and a setup inspired by causal influence theory, we present a variant of AIXI which learns to not seek arbitrary power; we call it "unambitious". We show that our agent learns to accrue reward at least as well as a human mentor, while relying on that mentor with diminishing probability. And given a formal assumption that we probe empirically, we show that eventually, the agent's world-model incorporates the following true fact: intervening in the "outside world" will have no effect on reward acquisition; hence, it has no incentive to shape the outside world.
