title: Introspection in Problem Solving
Creators: name: Jäkel, Frank

Publisher: name: Purdue Univ. Press
Year: 2025

description: Problem solving research has encountered an impasse. Since the seminal work of Newell und Simon (1972) researchers do not seem to have made much theoretical progress (Batchelder and Alexander, 2012; Ohlsson, 2012). In this paper we argue that one factor that is holding back the field is the widespread rejection of introspection among cognitive scientists. We review evidence that introspection improves problem solving performance, sometimes dramatically. Several studies suggest that self-observation, self-monitoring, and self-reflection play a key role in developing problem solving strategies. We argue that studying these introspective processes will require researchers to systematically ask subjects to introspect. However, we document that cognitive science textbooks dismiss introspection and as a consequence introspective methods are not used in problem solving research, even when it would be appropriate. We conclude that research on problem solving would benefit from embracing introspection rather than dismissing it.

description: As part of a study about the effects of further electrification in Denmark, the need arose to find some precise figures for the saving in running time on a given line, when converting diesel traction to electric traction. A neutral comparison of this, was not located, so with assistance from Bombardier, we decided to make a number of runtime calculations on Danish infrastructure, using either a diesel ITINO or an electric Talent 2. The models in the train families were chosen to have two trains that was very comparable. The two traction/speed curves can be seen below. Red for diesel, Green for electric. The calculations show that in the Danish regional/IC traffic, there is a saving potential in travelling time in the area of 5 – 10%. The saving potential is widely dependent on the type of operation and the infrastructure – operation with many stops while still being able to reach max speed in between stops naturally has the most potential. The potential saving in runtime per station stop is around 35 seconds.

(Figures 5A–B)
Paramaka pearljam Mariano, 2011: 46.
Diagnoses. Male imago: 1) abdominal color pattern with diffuse and extended brown marks, medially with a continuous line; 2) black medial line on terga continuous; 3) legs yellow, except for apical black band only on the hind femur; 4) posteromedial projection of styliger plate long and distally curved ventrally; 5) telopenis not sclerotized.
Nymph (putative): 1) labrum slightly wider than head capsule (1.3 x width of clypeus); 2) absence of projection on distal margin of clypeus; 3) tarsal claw without submarginal denticle; and 4) pointed projection on gills absent.
Material examined. BRAZIL, MATO GROSSO, Ribeirão Cascalheira, Fazenda Manaus, tributary of ribeirão Bonito, 2º ponte, 07.x.2007, 12°55'59"S 51°53'47" W, 329m, light trap, Pinho, L.C.; Mateus, S.; Torati, L. & Silva, F.R. cols., 2 male imagos (PARATYPES).
Distribution. BRAZIL (Mato Grosso).
Comments. The male imago of P. pearljam can be readily distinguished from the other species of the genus, except for P. takari sp. nov., by the long and ventrally curved medial projection of the styliger plate and the membranous nature of the telopenis. For the difference between P. pearljam and P. takari sp. nov., see the discussion below. The nymph is distinguished based on the absence of submarginal denticles on the tarsal claw and apical projection on gills.

description: In our presentation we explore the portability challenges and solutions encountered in adapting scientific applications to heterogeneous computing architectures using SYCL. To this end, we present two application porting efforts, HemeLB and DPEcho, spanning different scientific domains and requiring different porting strategies. DPEcho is a general relativistic magnetohydrodynamics (GR-MHD) code for compact, magnetized astrophysical objects, such as black hole accretion and stellar winds, or MHD waves. DPEcho is a SYCL + MPI rewriting of a legacy CPU-only Fortran application, written with the goals of source readability and cross-platform portability in mind. At the same time, we achieved a high performance on all tested hardware, and outperformed the original implementation on the same CPU architecture. HemeLB is a large-scale Lattice Boltzmann solver developed for simulating blood flow in sparse geometries such as the human vasculature system. It cleverly overlaps communication and computation to achieve good scaling on large-scale HPC systems. With a CUDA version already available, we pursued SYCL porting using the automatic Data Parallel C++ Compatibility (DPCT) tool, and then manually refactored sections of the code to account for differences between programming models. This resulted in a unified code tree which can execute on all major GPU architectures.

description: Stationer er ofte begrænsende for kapaciteten i jernbanenetværk da der er brug for ekstra spor når tog holder stille, tog har brug for længere opholdstid når de skifter køreretning og der (ofte) er konfliktende togveje. På trods af at stationer ofte udgør kapacitetsmæssige flaskehalse fokuserer de fleste metoder til analyse af jernbanekapacitet på den frie bane mellem stationerne. Denne artikel præsenterer tre forskellige metoder til at analysere stationskapacitet: • En metode til bestemmelse af behovet for perronspor på stationer • En skalerbar metode til at analysere konflikter i sporskiftezoner • En metode til analyse af hvor optimalt perronsporskapaciteten udnyttes ved at analysere togenes ankomst‐ og afgangsmønstre. Metoderne beskrevet i denne artikel kan bruges separat til at analysere specifikke karakteristika for stationskapacitet eller de kan kombineres til at give et detaljeret billede af stationskapaciteten. Derudover viser artiklen hvordan de udviklede metoder kan bruges til at analysere kapacitetsfremmende initiativer på Københavns Lufthavn, Kastrup station.

description: The histopathologic features of Adult Granulosa Cell Tumors (AGCTs) are relatively non-specific, resulting in misdiagnosis of other cancers as AGCT, a problem that has not been well characterized. FOXL2 mutation testing was used to stratify 336 AGCTs from three European centers into three categories: 1) FOXL2 mutant molecularly defined AGCT (MD-AGCT)(n=256 of 336), 2) FOXL2 wild-type AGCT (n=17 of 336), 3) misdiagnosed other tumor types (n=63 of 336). All statistical tests were two-sided. The overall and disease-specific survival of the misdiagnosed cases was lower than in the MD-AGCTs (P<0.001). The misdiagnosed cases accounted for 71.9% of disease-specific deaths within five years. In the population-based cohort, overall survival of MD-AGCT patients was not different from age-matched population-based controls. Even though 35.2% of all the MD-AGCT patients, in our study, experienced a relapse, AGCT is usually an indolent disease. The historical, pre-molecular data underpinning our clinical understanding of AGCT was likely skewed by inclusion of misdiagnosed cases, and future management strategies should reflect the potential for surgical cure and long survival even after relapse.

description: Wave function collapse remains a fundamental question in quantum mechanics, especially concerning how physical data contributes to this process. In this study, we utilized the o1-mini simulator to model quantum decoherence with a focus on entropy evolution and interference pattern degradation. Key findings include an exponential decay in interference contrast (C(t) ∼ exp(-γt)) and a monotonic increase in von Neumann entropy (S(t)). These results demonstrate that physical data plays a critical role in guiding wave function collapse, offering a new perspective that complements traditional decoherence theory.

description: Atkins har for Holstebro, Herning og Ringkøbing-Skjern Kommuner udarbejdet et forslag til opgradering af regionalbanerne i Vestjylland. Baggrunden for forslaget var, at der ikke var nogen klar strategi for banerne i Midt- og Vestjylland, bortset fra at skinnelegemet skal moderniseres, og at et nyt signalsystem indføres omkring 2020-22. Disse tiltag vil i sig selv formentlig ikke medføre flere passagerer, og for at fastholde og øge passagertallet må der nødvendigvis ske en række passagervendte tiltag, der vil det gøre det mere attraktivt at rejse med toget. Tiltagene kan være flere tog, bedre stationer og ikke mindst kortere rejsetid. På kort sigt, dvs. indenfor ca. 5-10 år, foreslås mindre tilpasning af infrastruktur, etablering af nye krydsningsspor samt opgradering af hastigheden til 120 km/t, hvor dette ikke er tilfældet i dag. Trafikalt skal der sikres bedre sammenhæng mellem systemer, kortere skiftetider og omlægninger i ruter så lange skift minimeres eller undgås. Togsystemerne differentieres i regionale stoptog og hurtige regionale togsystemer med få stop (REX-tog eller IC-tog), som tilpasses i en grundkøreplan med timedrift eller 1⁄2- times drift. Dette gør det muligt at løfte kvalitet, regularitet, køretid og trafikudbud mærkbart. På længere sigt, dvs. 10 år og derover, udnyttes gevinsten af det nye signalsystem og gennemførte spormoderniseringer, således hastigheden kommer op på 140 km/t. Alle overkørsler foreslås sikret med bomanlæg, erstattet af niveaufri eller nedlagte krydsninger. På de passagertunge strækninger mellem Silkeborg-Herning og Vejle-Herning foreslås de mest kurverige strækningsafsnit udrettet og hastigheden generelt opgraderet til 180 km/t samt etablering af dobbeltspor på hovedparten af strækningerne. En helt ny dobbeltsporet bane til 180 km/t fra Århus til Silkeborg via Galten bør etableres, for at nedbringe rejsetiden mellem Vest- og Østjylland markant. Dette kan løfte banekapaciteten mærkbart og reducere køretiden så meget, at jernbanen kan komme til at konkurrere med biltrafikken på det udbyggede motorvejsnet. Der er ikke foretaget egentlig økonomiske beregninger af investeringsbehovet på kort og lang sigt, og følgelig er der ikke gennemført samfundsøkonomiske beregninger. Disse bør gennemføres, når de implicerede kommuner har aftalt de strategiske mål for jernbanerne i Vestjylland.

description: Rare cancers, as a collective, account for approximately one-quarter of all cancer diagnoses and deaths. Historically, they have been divided into two groups. The first was defined by their unusual histogenesis (cell of origin or differentiation state), and include chordomas or adult granulosa cell tumours (aGCT). Most tumour types from this first group are still clinically and biologically relevant and have been disproportionally important as sources of insight into cancer biology. The second grouping of rare cancers were histologically defined subtypes of common cancers, most of which have been shown to have neither defining molecular features, nor clinical utility. ‘Omics based analyses has splintered common cancers into a myriad of molecularly rather than histologically, defined subsets of common cancers, many of which have immediate clinical relevance. Today, almost all rare cancers are either histomolecular entities, which often have pathognomonic mutations, or molecularly defined subsets of more common cancers. The presence of specific genetic variants provides rationale for testing targeted agents in rare cancers, however, the essential contributions of both mutation and cell context in the development, biology, and behaviour of these cancers suggest that designing trials of drugs based on the presence of mutations, without consideration of cellular context (the specific genomic and signalling architecture in which mutations operate) is naïve. Patients with rare cancers are disadvantaged due to challenges of participating in clinical trials however, the number of patients with rare cancers will only increase as more molecular subsets of common cancers are identified, and as this happens, it will be necessary to shift the focus of clinical trials and research to cancer types, which by epidemiological definitions are rare tumours.

Remarks. This morphospecies is in the process of description by one of us (FFS). Only one specimen was found on the samples. Although the shape of the styliger plate resembles Paramaka pearljam Mariano 2011, the projection (sharp on Paramaka sp. versus curved apically on P. pearljam), the general color, the pattern of spots on the abdomen, and the proportion between penes lobes/styliger plate (2/3 the length on Paramaka sp. versus 3/2 the length on P. pearljam) are different from P. pearljam. Additionally, this specimen appears to be very close to the Paramaka sp. mentioned by Lima et al. (2016) from the state of Bahia. It was found in only one site, in an area with Cerrado influence.

description: Laboratory experiments have been carried out in the directional wave tank at Marintek (Norway) to study the nonlinear dynamics of surface gravity waves and the occurrence of extreme events, when the wave field traverses obliquely an ambient current. A condition of partial opposition has been considered. Tests on regular waves have shown that the current can trigger the formation of large amplitude waves. In random wave fields, however, this only results in a weak deviation from the statistical properties observed in absence of a current.

description: Can people who have had long stays in psychiatric institutions be supported to live independently in the community? This article reports on a study that considers programs providing this support in two Australian cities. When psychiatric hospitals close, people residing in them need housing. Many also need support to enable them to live independently in the community. Since the inception of the National Mental Health Strategy in 1992 various models of support and housing have been developed for this group. This article discusses a research project being undertaken by the Institute for Social Research at Swinburne University of Technology in Melbourne that considers one of these models.

description: In this work, image receivers are characterized to address the challenges of indoor positioning with optical wireless location (OWL) systems. Image receivers are studied according to their field-of-view (FOV) characteristics: the first image receiver uses a wide-FOV (95°) microlens; the second image receiver uses an ultrawide-FOV (130°) microlens. An angle of arrival (AOA) characterization of the image receiver is used to quantify azimuthal, φ, and polar, θ, angles of incident light from optical beacons. A dilution of position (DOP) characterization is used to quantify geometrical effects of the optical beacon distribution. It is found that the ultrawide-FOV microlens (with a mean positioning error of 1.5 cm) can better image widely separated optical beacons, and thus operate at a lower DOP, compared to the wide-FOV microlens (with a mean positioning error of 3.2 cm).

description: Background: Early childhood education and care (ECEC) is crucial for shaping physical activity (PA) behaviours due to the significant time children spend in this setting. In addition, research has shown that public policies can be an important means to create a healthy environment. This systematic review explores the effectiveness of public policies promoting PA in ECEC. Methods: Nine online databases (Scopus, Pubmed, Web of Science, SportDiscus, Cinahl, IBSS, ERIC, APA PsychINFO and Cochrane library) were searched in August 2023 for studies that examined public policies impacting children's PA behaviour or environments in ECEC. Data were extracted, and a quality assessment was performed using the Downs and Black checklist, and a narrative synthesis was applied. Results: A total of 11 articles met the inclusion criteria. The studies from the United States, Canada and Australia involved either the implementation of legally binding policies (n=6) or voluntary accreditation standards (n=5). Studies reported on the adher?ence of ECEC centres to policies, the effects on children's PA behaviour or changes in the environment using both device-based (e.g., accelerometer) and self-report (e.g., questionnaires and interviews) measures as well as observation. Reported adherence rates of childcare centres to new regulations ranged from 74% to 94%. Studies on policies that implemented PA into the curriculum required a mandatory PA time of at least 60min per day or implemented revised accreditation standards reported positive effects on the ECEC centres PA environment. Effects on the PA behaviour of children remained inconclusive, with studies reporting on both increased and decreased PA levels. Conclusion: Public policies have the potential to change the environment and positively influence PA behaviour in preschool children. However, due to the heterogenous methodological approaches in the identified studies, the findings of this review have certain limitations. Future research needs to further investigate the effectiveness of policy approaches to promote PA in early childhood settings.

description: Purpose: This paper synthesizes existing research on tools and methods that support data-driven business model innovation, and maps out relevant directions for future research. Design/methodology/approach: We have carried out a structured literature review and collected and analysed a respectable but not excessively large number of 33 publications, due to the comparatively emergent nature of the field. Findings: Current literature on supporting data-driven business model innovation differs in the types of contribution (taxonomies, patterns, visual tools, methods, IT tool and processes), the types of thinking supported (divergent and convergent) and the elements of the business models that are addressed by the research (value creation, value capturing and value proposition). Research limitations/implications: Our review highlights the following as relevant directions for future research. Firstly, most research focusses on supporting divergent thinking, i.e. ideation. However, convergent thinking, i.e. evaluating, prioritizing, and deciding, is also necessary. Secondly, the complete procedure of developing data-driven business models and also the development on chains of tools related to this have been under-investigated. Thirdly, scarcely any IT tools specifically support the development of data-driven business models. These avenues also highlight the necessity to integrate between research on specifics of data in business model innovation, on innovation management, information systems and business analytics. Originality/value: This paper is the first to synthesize the literature on how to identify and develop data-driven business models, and to map out (interdisciplinary) research directions for the community.

Year: 2025

description: This paper introduces the Entropy-Induced Collapse (EIC) model, a novel framework for wave function collapse driven by an entropy threshold  S_{\text{crit}} .

The proposed model integrates thermodynamic principles with Quantum Error Correction (QEC) and uses a Lindblad-type master equation to describe collapse dynamics triggered when the environment’s entropy exceeds a critical value.

 

By quantifying the transition from quantum superposition to classical outcomes, this theory addresses long-standing challenges in the measurement problem.

 

Key contributions include:

 1. A mathematical framework connecting environmental entropy with wave function collapse.

 2. Experimental proposals involving superconducting qubits and optical interferometry.

 3. Comparisons with existing theories, such as GRW, decoherence models, and quantum error correction frameworks.

 

Potential applications range from improving quantum error correction (QEC) to explaining the emergence of classical structures during cosmic inflation.

This work bridges quantum mechanics and thermodynamics, offering a testable hypothesis for the quantum-to-classical transition.

Entropy-Induced Collapse (EIC): From Quantum Foundations to the Fifth Force
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper introduces the Entropy-Induced Collapse (EIC) model, a novel framework that integrates thermodynamic principles, quantum error correction (QEC), and non-Markovian memory effectsto describe wavefunction collapse. Unlike conventional collapse models, EIC postulates that collapse occurs when the environmental von Neumann entropy  S(t)  exceeds a dynamically modulated critical threshold  S_{\text{crit}}(t) .

 

Key Contributions

 • Fractal entropy fluctuations: The model incorporates fractional Brownian motion (fBm) to capture scale-invariant noise characteristics, improving robustness in quantum systems.

 • Information Field & Fifth Force Perspective: A new Lagrangian formulation for an information field  \Phi(x,t)  is introduced, suggesting a possible fifth fundamental forcemediated by entropy gradients.

 • Nonlocality & Black Hole Information: The model predicts entanglement-preserving collapse dynamics, providing insights into the ER=EPR conjecture and black hole evaporation.

 • Cosmological Implications: The model suggests a detectable imprint in the CMB E-mode polarization spectrum ( k_{\text{crit}} \sim 0.01  Mpc^{-1}), with potential validation using Planck 2018 data and LiteBIRD.

 • Quantum Cryptography & Computing: Dynamic control of  S_{\text{crit}}  is proposed to enhance quantum key distribution (QKD) protocols and improve qubit coherence in fault-tolerant quantum computing.

 

Experimental Validation & Future Prospects

 

EIC is testable through superconducting qubits, trapped ions, optical interferometry, and Rydberg atom experiments. Machine learning-based real-time entropy tracking is proposed to refine predictions.

 

This extended version further refines the mathematical framework, presents new numerical simulations, and discusses implications for quantum gravity, black hole physics, and cosmology.
Entropy-Induced Collapse (EIC): A Deterministic-Stochastic Framework Integrating Quantum Error Correction and Non-Markovian Dynamics
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper introduces the Entropy-Induced Collapse (EIC) model, a novel approach to wavefunction collapse based on entropy dynamics, fractal noise, and quantum error correction (QEC). The key hypothesis is that collapse occurs when the environmental von Neumann entropy S(t) exceeds a dynamically evolving threshold S_{\mathrm{crit}}(t), influenced by non-Markovian memory effects.

 

Key Contributions:

 • Entropy-Driven Collapse: Collapse is defined as a deterministic-stochastic process governed by entropy fluctuations.

 • Fractal Noise and Non-Markovianity: The model incorporates fractional Brownian motion (fBm) to capture long-range correlations.

 • Quantum Error Correction (QEC): The impact of QEC on delaying collapse is explored through simulation data up to code distance d=11.

description: The subject of the thesis deals with the anisotropy elastoplastic constitutive behavior law identication in the aim of its use for the numerical simulation of the metal sheet deep drawing processes. Essentially, we have contributed to the denition and the application of constitutive behaviour identication techniques and strategies from experimental tests. The classical tests used for the identification Simple tensile tests, in the axes and off-axes, plane tensile test and the bulge test (as an alternatif of the equibiaxial test) are presented and analyzed from the point of view of the deformation homogeneity to outcome to the stress-strain relation from the globales measurements force-displacement. The identification of the behavior laws from inhomogeneous tests needs numerical simulation coupled with an optimisation procedure (simplex method) for minimizing the difference between measured results and model responses calculated by finite element method. We have identified anisotropy elastoplastic behaviour laws with isotropy hardening law. These laws are based on the choice of the constitutive functions "equivalent stress", which defines the yield locus and plasticity potential (non associated plasticity) that has the same form as the yield function. Several quadaratic and non quadratic yield loci are then used. We have developed a specic sensitivity analysis method of the tests in relation to the identified behaviour law parameters. This method is applied on practical examples.

description: Die Förderung von Kindern gewinnt an Bedeutung in den Schweizer Gemeinden. Dies zeigt sich in der Bestärkung von Kinder- und Jugendförderung in politischen Zielen und der Steigerung der Vielfalt von Förder- und Freizeitangeboten für Kinder. Eine ähnliche Entwicklung lässt sich in den drei grossen Jugendverbänden der Schweiz Pfadi, Jungwacht Blauring (Jubla) und Cevi beobachten. Seit einigen Jahren bauen sie vermehrt ihr Angebot für Kinder im Vorschulalter aus. Diese Masterthesis sucht nach Chancen und Möglichkeiten, wie Jugendverbände mit ihren Angeboten für Kinder im Vorschulalter die Gemeinden (im Kanton Aargau) unterstützen können. Gleichzeitig werden Wege aufgezeigt, wie sich Jugendverbände in der Gemeinde besser einbetten können. In einem qualitativen Forschungsprozess wurde mit der Methodik der Triangulation gearbeitet. Den Kern der Arbeit bildet die Analyse von Massnahmenplänen zur Kinderförderung einiger Aargauer Gemeinden sowie von Ausbildungsunterlagen der Jugendverbände. Ergänzend kam der Feldforschungszugang in zwei Ausbildungskursen der Jugendverbände dazu sowie spezifizierende Experten- und Fokusinterviews mit Fachkräften. Die Untersuchungsergebnisse zeigen, dass kaum Vernetzung unter den Vorschulstufengruppen der Jugendverbände mit anderen Akteuren in der Kinderförderung besteht. Die empirischen Ergebnisse verdeutlichen weiter, dass die Gemeinden insbesondere in der Bewegungsförderung, im Umgang mit Menschen sowie in der Förderung von Chancengleichheit und Mitbestimmung stärker von den Jugendverbänden profitieren können. Auf Seiten der Gemeindeanalyse konnte die Bedeutung der Nutzung von Synergien und der Koordination bestehender Angebote nochmals aufgezeigt werden. Auf jeden Fall sollten Jugendverbände die Vorzüge ihrer Angebote bei den Gemeinden präsentieren und Kanäle nutzen, diese bekannt zu machen. Gleiches gilt für Gemeinden: Sie tragen zur Vielfalt der gemeindeeignen Angebotslandschaft bei, indem sie die Angebote der Jugendverbände in ihre Strategie der Kinder- und Jugendförderung miteinbeziehen.

Entropy-Induced Collapse (EIC): A Deterministic-Stochastic Framework Integrating Quantum Error Correction and Non-Markovian Dynamics
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper introduces the Entropy-Induced Collapse (EIC) model, a novel approach to wavefunction collapse based on entropy dynamics, fractal noise, and quantum error correction (QEC). The key hypothesis is that collapse occurs when the environmental von Neumann entropy S(t) exceeds a dynamically evolving threshold S_{\mathrm{crit}}(t), influenced by non-Markovian memory effects.

 

Key Contributions:

• Entropy-Driven Collapse: Collapse is defined as a deterministic-stochastic process governed by entropy fluctuations.

• Fractal Noise and Non-Markovianity: The model incorporates fractional Brownian motion (fBm) to capture long-range correlations.

• Quantum Error Correction (QEC): The impact of QEC on delaying collapse is explored through simulation data up to code distance d=11.

• Experimental Roadmap: Proposed tests using superconducting qubits (IBM Quantum, Google Sycamore) and trapped ion systems.

• Implications for Quantum Cryptography: Effects on quantum key distribution (QKD) security under non-Markovian noise are analyzed.

 

This work aims to unify quantum foundations, quantum computing, and quantum information theory by providing a testable framework for entropy-induced collapse.

Free-Space Optical Communications Over Lognormal Fading Channels Using OOK With Finite Extinction Ratios

description: Free-space optical communication links operating over lognormal turbulence channels using on-off keying (OOK) are studied in this work. Such systems can suffer from irreducible error floors that result from the use of demodulation with fixed and unoptimized detection thresholds. The resulting error floors are analyzed for the general case of low and high state offsets (i.e., finite extinction ratios). An electrical signal-to-noise ratio (SNR) optimized detection system is applied. The system uses the electrical SNRs to implement adaptive detection thresholds and eliminate the error floors. The system can accommodate operation with finite extinction ratios, as it uses the method of moments and maximum likelihhod estimation techniques to estimate the low and high state offsets and electrical SNR. Numerical results show that the SNR gap between the electrical-SNR-optimized detection system and the adaptive detection system is 2:3 dB at a bit-error rate of 10-⁵ without a state offset. The SNR gap increases to 4:5 dB with a state offset of = 0:2.
Entropy-Induced Collapse in Black Holes, the Early Universe, and Quantum Cryptography: A Unified Framework with Observational and Experimental Tests
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This repository presents an extended application of the Entropy-Induced Collapse (EIC) model, integrating quantum error correction (QEC) and non-Markovian fractal noise into the study of black hole information dynamics, early universe cosmology, and quantum cryptography. The EIC model posits that wavefunction collapse occurs when the environmental von Neumann entropy S(t)surpasses a dynamically evolving threshold S_crit(t), which is influenced by QEC effects and long-range memory correlations.

 

This work includes:

• Black Hole Physics: A QEC-modified Page time derivation, showing that quantum error correction extends information retention in evaporating black holes, offering a new perspective on the information paradox.

• Cosmic Microwave Background (CMB) Predictions: A dynamically modulated collapse threshold during inflation leads to a testable spectral feature in CMB E-mode polarization, with implications for future missions such as LiteBIRD and CMB-S4.

• Quantum Cryptography Implications: The effect of non-Markovian fractal noise on quantum key distribution (QKD) protocols, demonstrating that increasing the Hurst exponent Hleads to higher quantum bit error rates (QBER) and reduced secure key rates.

• Computational and Experimental Validation: High-performance computing (HPC) simulations quantifying entropy dynamics across multiple regimes, along with a roadmap for experimental tests using superconducting qubits (IBM Quantum, Google Sycamore) and trapped-ion platforms.

 

All simulation codes, datasets, and Python analysis scripts are provided in this repository for full reproducibility. The results contribute to a deeper understanding of wavefunction collapse mechanisms, quantum information preservation, and entropy-driven cosmological phenomena.

description: Consider a finite directed graph without cycles in which the arrows are weighted. We present an algorithm for the computation of a new distance, called path-length-weighted distance, which has proven useful for graph analysis in the context of fraud detection. The idea is that the new distance explicitly takes into account the size of the paths in the calculations. Thus, although our algorithm is based on arguments similar to those at work for the Bellman-Ford and Dijkstra methods, it is in fact essentially different. We lay out the appropriate framework for its computation, showing the constraints and requirements for its use, along with some illustrative examples.

Entropy-Induced Collapse (EIC) Model Series: Information Field and a Fifth Force Hypothesis
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper presents a comprehensive theoretical framework that extends the Entropy-Induced Collapse (EIC) model by introducing an information field \Phi(x,t) as a candidate for a non-equilibrium fifth force. Unlike conventional approaches where entropy is merely a state function, our model establishes that entropy gradients generate a physically distinct “information energy” capable of mediating a novel interaction. This interaction, driven by local entropy variations analogous to heat flow induced by temperature gradients, is formulated rigorously through a Lagrangian framework and field equations.

 

Key contributions of this work include:

1. Formal derivation of a field equation where entropy gradients act as a source for \Phi(x,t), supported by a consistent energy density formulation.

2. Introduction of a higher-dimensional information projection mechanism to explain how \Phi(x,t) emerges in observable spacetime under non-equilibrium conditions.

3. Detailed comparison with existing fifth-force theories, emphasizing how our model uniquely avoids Equivalence Principle violations and remains hidden under equilibrium.

4. Experimental verification strategies, ranging from short-term (torsion balance, MEMS sensors, Casimir effect), mid-term (CMB polarization anomalies), to long-term (gravitational wave interferometry and black hole observations).

5. Reinterpretation of existing anomalies such as Atomki Beryllium-8 decay and the Muon g-2 discrepancy in light of an entropy-driven force.

 

This framework positions entropy not as a passive thermodynamic quantity but as an active source of a fundamental interaction, potentially bridging quantum measurement, gravity, and non-equilibrium physics. While further experimental validation is ongoing, this work establishes a novel theoretical foundation that may resolve several open problems in modern physics.

Using Multi-Arm Bandits to Optimize Game Play Metrics and Effective Game Design
Creators: name: Raharjo, Kenny

Year: 2016

description: Game designers have the challenging task of building games that engage players to spend their time and money on the game. There are an infinite number of game variations and design choices, and it is hard to systematically determine game design choices that will have positive experiences for players. In this work, we demonstrate how multi-arm bandits can be used to automatically explore game design variations to achieve improved player metrics. The advantage of multi-arm bandits is that they allow for continuous experimentation and variation, intrinsically converge to the best solution, and require no special infrastructure to use beyond allowing minor game variations to be deployed to users for evaluation. A user study confirms that applying multi-arm bandits was successful in determining the preferred game variation with highest play time metrics and can be a useful technique in a game designer's toolkit.
