Wir schlagen ein kosmologisches Szenario vor, in dem das heiße Urknall-Universum durch die Kollision einer Brane im erweiterten Raum mit einer begrenzenden Orbifold-Ebene erzeugt wird, ausgehend von einem ansonsten kalten, leeren, statischen Universum. Das Modell behandelt das Problem des kosmologischen Horizonts, die Frage nach der Geometrie und das Monopolproblem und erzeugt ein nahezu skaleninvariantes Spektrum von Dichteschwankungen, ohne eine superluminale Ausdehnung (Inflation) zu postulieren. Das Szenario stützt sich stattdessen auf physikalische Phänomene, die in Theorien mit zusätzlichen Dimensionen und Branen natürlich entstehen. Als Beispiel präsentieren wir unser Szenario vor allem im Kontext der Heterotic-M-Theorie. Eine Vorhersage, die dieses Szenario von der Standard-Inflationskosmologie unterscheidet, ist ein stark blaues Gravitationswellenspektrum, das Konsequenzen für Experimente zur Polarisation des Mikrowellenhintergrunds und für Gravitationswellendetektoren hat.

The scenario relies, instead, on physical phenomena that arise naturally in theories based on extra dimensions and branes.

Abstract. In this paper we discuss the properties of the quasi-steady state cosmological model (QSSC) developed in 1993 in its role as a cyclic model of the universe driven by a negative energy scalar field. We discuss the origin of such a scalar field in the primary creation process first described by F. Hoyle & J. V. Narlikar forty years ago. It is shown that the creation processes which take place in the nuclei of galaxies are closely linked to the high energy and explosive phenomena, which are commonly observed in galaxies at all redshifts. The cyclic nature of the universe provides a natural link between the places of origin of the microwave background radiation (arising in hydro-gen burning in stars), and the origin of the lightest nuclei (H, D, He3 and He4). It also allows us to relate the large scale cyclic properties of the uni-verse to events taking place in the nuclei of galaxies. Observational evi-dence shows that ejection of matter and energy from these centers in the form of compact objects, gas and relativistic particles is responsible for the population of quasi-stellar objects (QSOs) and gamma-ray burst sources in the universe. In the later parts of the paper we briefly discuss the major unsolved problems of this integrated cosmological and cosmogonical scheme – the understanding of the origin of the intrinsic redshifts, and the periodicities in the redshift distribution of the QSOs. Key words. Cosmology—cosmogony—high energy phenomena. 1.

Based on an earlier introduced new class of generalized gravity‐matter models defined in terms of two independent nonRiemannian volume forms (alternative generally covariant integration measure densities) on the space‐time manifold, we derive an effective “Einstein‐frame” theory featuring the following remarkable properties: (i) We obtain effective potential for the cosmological scalar field possessing two infinitely large flat regions which allows for a unified description of both early Universe inflation as well as of present dark energy epoch; (ii) for a specific parameter range the model possesses a non‐singular stable “emergent Universe” solution which describes an initial phase of evolution that precedes the inflationary phase.

Die Geisterkondensation des frühen Universums in einer Prä-Urknall-Phase wurde in diesem Papier im Verlauf eines nicht-singulären Bounces vorgestellt. Das sich entwickelnde Universum kontrahiert zunächst und geht anschließend über einen Post-Big-Bang-Abschnitt reibungslos in ein expandierendes Universum über. Zunächst treten und werden danach Ghost-ähnliche Instabilitäten gedämpft, die Null-Energie-Bedingung (NEC) wird explizit durch den Krümmungsmechanismus einer adiabatisch gestörten Metrik verletzt. Der Vakuumzustand der laufenden Phase wird über eine Lagrangefunktion stabilisiert, die im Kern den Vakuumzustand gegenüber Ableitungen höherer Ordnung stabilisiert. Die Verletzung der NEC betrifft eine katastrophale Vakuuminstabilität, die mit einer Korrektur bei kleinen Energien und Momenten unterhalb der UV-Cutoff-Skala erneut auftritt und potenziell problematisch sein könnte, wenn man versucht, eine UV-abgeschlossene Theorie dieses Ekpyrotik-Modells zu konstruieren. Die skaleninvariante Krümmungsstörung, die aus skaleninvarianten Entropieperturbationen zweier Ekpyrotik-Skalarfelder hervorgeht, wird im Gegensatz dazu aufgrund der nicht-singulären Struktur der Hintergrundgeometrie auf den Super-Horizont-Grenzen konstant. Abgesehen von den Geisterkondensaten behandelt diese Theorie die neue Ekpyrotik-Theorie, die sich als unterscheidbare Alternative zur Inflations-Theorie zur Entstehung des Universums herausstellt. Entsprechend den jüngsten WMAP-Daten weist das Ekpyrotik-Modell eine spektrale Rot-Verschiebung auf, die zeigt, dass das geboosten skalare Potential während der Materie-Fluktuationen in der heißen Urknall-Phase durch einen negativen Phasenversatz fällt.

    abstract = "The ghost condensation of the early universe in a pre-big bang phase has been presented in this paper through duration of a non-singular bounce. The undergoing universe contracts and passes smoothly in an expanding universe via a post-big bang phase. Initially developing and then taming any ghost like instabilities, the Null Energy Condition (NEC) is explicitly violated through the curvature mechanism of an adiabatic perturbed metric. The vacuum state of the ongoing phase is stabilized via a Lagrangian that in essence stabilizes the vacuum state under the higher order derivatives. The violation of the NEC regards a catastrophic vacuum instability, which re-emerges with a correction valid at small energies and momenta, below the UV-cut-off scale that, could potentially be problematic if one tries to construct a UV-completed theory of this Ekpyrotic model. The scale-invariant curvature perturbation, that arises and is sourced out of the scale-invariant entropy perturbations sourced by 2-Ekpyrotic scalar fields, that, in contrast, becomes constant on the super-horizon limits, due to the non-singular nature of the background geometry. Apart, from the ghost condensates, this theory addresses the new Ekpyrotic theory which in order becomes a distinguishable alternative to inflation theory for the birth of the universe. As per the recent WMAP data, the Ekpyrotic model has a spectral red tilt that shows the bounced scalar potential falling through a negative phase shift during the matter-fluid fluctuations in the hot big bang phase.",

Wir schlagen vor, dass der Urknall keinen singulären Anfang hat, sondern aus dem gravitativ bedingten Kollaps einer Niedrigdichtelukloud hervorgeht, die vor 25 Gyr kollabierte und ein Schwarzes Loch (BH) mit der Masse M ≃ 6 × 1022M⊙ bildete. Der Kollaps setzte sich innerhalb des BH über 11 Gyr fort, bis die Dichte Neutronen-Entartung erreicht und der Kollaps in eine Expansion zurückschwingt, ähnlich einer Kernkollaps-Supernova. Nach heutigen Beobachtungen ähnelt dieses Modell der Standard-Urknall-Kosmologie sehr, jedoch besteht kein Bedarf für Inflation oder Dunkle Energie (DE). Die beobachtete kosmologische Konstante Λ ist keine neue Form von DE, sondern resultiert aus der Dynamik der Urknall-Expansion innerhalb des BH-Ereignishorizonts rS = 2GM = √3/Λ. Warum hat unser Universum eine so große Masse M (oder einen so kleinen Λ‑Wert)? Wenn τO(≃ 10 Gyr) die astronomische Zeitskala ist, die notwendig ist, damit Beobachter wie wir existieren können, ergeben sich einfache anthropische Vorhersagen, die allein auf Gravitätskollaps aus Gaußschen Fluktuationen beruhen und eine maximale Wahrscheinlichkeit für M von MO < M < 3MO liefern, wobei MO = τO/3G. Das stimmt gut mit den gemessenen Werten für τO und M in unserem Universum überein.

The collapse continued inside the BH for 11Gyrs until the density achieves neutron degeneracy and the collapse bounces into expansion like a core collapse supernova. From observations today, this model is very similar to the standard Big Bang cosmology but there is no need for Inflation or Dark Energy (DE). The observed cosmological constant \Λ is not a new form of DE, but results from the dynamics of the Big Bang expansion inside the BH event horizon rS = 2GM = \√3/\Λ. Why our Universe has such a large mass M (or small \Λ value)? If \τO(≃ 10Gyr) is the astronomical timescale needed for observers like us to exist, we find a simple anthropic prediction, based only on gravitational collapse from Gaussian fluctuations, that the maximum probability for M is MO \< M \< 3MO where MO = \τO/3G.

Die zunehmende Penetration verteilter Erzeugung (DG) hat den Schutzschutzkoordinationsaufwand in modernen Verteilnetzen durch bidirektionale Leistungsflüsse und variable Fehlerstromstärken erheblich verkompliziert. Diese Herausforderungen werden unter verschiedenen Betriebsmodi deutlicher, insbesondere im Inselbetrieb, wo verminderte Fehlerstromwerte strenge Grenzen für die Koordination von Überstromrelais (OCR) setzen. Dieses Papier stellt eine vergleichende Bewertung metaheuristischer Optimierungstechniken für die Koordination von Überstromschutz in DG-integrierten Verteilnetzen vor. Es werden zwei Verteilnetze mit unterschiedlichen topologischen Eigenschaften untersucht. Ein radialer 9-Bus-System wird in drei Betriebsmodi analysiert: konventioneller netzgebundener Betrieb ohne DG, DG-integrierter netzgebundener Betrieb und Inselbetrieb. Demgegenüber wird ein meshed 30-Bus-Verteilungssystem ausschließlich unter Inselbetrieb bewertet, um die anspruchsvollsten Koordinationsbedingungen zu repräsentieren, bei denen der Fehlerstrom bei inverterbasierten DG-Quellen begrenzt ist. Die Relais-Koordination wird als ein Optimierungsproblem mit Nebenbedingungen formuliert, das die Minimierung der gesamten Relais-Auslösezeit bei gleichzeitiger Erfüllung der Anforderungen an das Koordinationszeitintervall (CTI) anstrebt. Unter identischen Schutzmodellen und Fehlerbedingungen werden drei metaheuristische Optimierungsalgorithmen angewandt: der Genetische Algorithmus (GA) als konventioneller Referenzansatz sowie der Water Cycle Algorithm (WCA) und der Big Bang-Big Crunch (BB-BC)-Algorithmus als neuere Techniken. Kurzschlussberechnungen werden für Drehstromfehler gemäß der Norm IEC 60909 durchgeführt. Die Ergebnisse zeigen, dass alle untersuchten Algorithmen erfolgreich abgestimmte Relais-Einstellungen in den betrachteten Betriebsmodi erreichen.

    abstract = "The increasing penetration of distributed generation (DG) has significantly complicated protection coordination in modern distribution networks by introducing bidirectional power flows and variable fault current levels. These challenges become more pronounced under different operating modes, particularly in islanded operation, where reduced fault current levels place severe constraints on overcurrent relay (OCR) coordination. This paper presents a comparative assessment of metaheuristic optimization techniques for coordinating overcurrent protection in DG-integrated distribution networks. Two distribution systems with different topological characteristics are examined. A radial 9-bus system is analyzed under three operating modes: conventional grid-connected operation without DG, DG-integrated grid-connected operation, and islanded operation. In contrast, a meshed 30-bus distribution system is evaluated exclusively under islanded operation to represent the most demanding coordination conditions, where fault current support is limited to inverter-based DG sources. Relay coordination is formulated as a constrained optimization problem aimed at minimizing total relay operating time while satisfying coordination time interval (CTI) requirements. Three metaheuristic optimization algorithms are applied under identical protection models and fault conditions: the Genetic Algorithm (GA) as a conventional reference approach, and the Water Cycle Algorithm (WCA) and Big Bang-Big Crunch (BB-BC) algorithm as more recent techniques. Short-circuit calculations are performed for three-phase faults in accordance with IEC 60909 standards. The results indicate that all investigated algorithms successfully achieve coordinated relay settings under the examined operating modes.",

Wir präsentieren ein quantenfeldtheoretisches quadratisches Gravitationsinflationsszenario, das die neuen kosmologischen Randbedingungen berücksichtigen kann, welche das Starobinsky-Modell der Inflation verworfen haben. Die Theorie ist im Ultraviolett-Bereich asymptotisch frei, aber die 1‑Loop-Laufzeit führt dynamisch zu einer langsamen Roll-Inflation in Richtung Infrarot. Wenn eine große Anzahl von Materie-Feldern zu den Beta-Funktionen beiträgt, können der spektrale Index und das Tensor-zu-Skalar-Verhältnis phänomenologisch zulässig sein. Wir finden, dass beim Ende der Inflation die Theorie in ihr Regime starker Kopplung eintritt und die Allgemeine Relativitätstheorie als effektive Feldtheorie entstehen muss, da das Universum wieder aufheizen und in seine Standard-Radiationsphase eintreten muss. Um starke Kopplung zu vermeiden, wird für diese Theorie ein minimales Tensor-zu-Skalar-Verhältnis von 0,01 vorhergesagt. Unser Rahmenwerk bietet ein Labor, das eine konkrete ultraviolette Vervollständigung (quantenquadratische Gravitation) mit Inflationsdynamik, Reheating und präzisen kosmologischen Beobachtungen verbindet.

The theory is asymptotically free in the ultraviolet, but 1-loop running is found to dynamically lead to slow-roll inflation toward the infrared. When a large number of matter fields contribute to the beta functions, the spectral index and the tensor-to-scalar ratio can be phenomenologically viable. We find that as inflation ends, the theory approaches its strong coupling regime and general relativity must emerge, as an effective field theory, as the universe must reheat and enter its standard radiation era. In order to avoid strong coupling, a minimum tensor-to-scalar ratio of 0.01 is predicted for this theory.

Wir berichten über eine hochpräzise Messung der Photodissoziationsreaktion D(γ,n)p an der neu in Betrieb genommenen Shanghai Laser Electron Gamma Source unter Verwendung eines quasimonochromatischen γ-Strahlungsbündels aus Laser-Compton-Streuung. Die Wirkungsquerschnitte wurden im Bereich E_{γ}=2,327–7,089 MeV bestimmt und erreichen nahe der Neutronenemissionsschwelle eine bis zu 2,2-fache Verbesserung der Präzision. In Kombination mit früheren Daten in einer globalen Markov-Chain-Monte-Carlo-Analyse unter Verwendung der dibaryon effektiven Feldtheorie erhielten wir die bisher unvergleichlich präzisen p(n,γ)D-Wirkungsquerschnitte und thermonuklearen Raten mit bis zu ≈4-fach höherer Präzision als frühere Auswertungen. Eingebettet in einen Standardrahmen der Urknall-Nukleosynthese verringert diese neue Rate die Unsicherheit des zentralen kosmologischen Parameters für die Baryonendichte Ω_{b}h^{2} gegenüber dem Ergebnis des Labor for Underground Nuclear Astrophysics (LUNA) um bis zu ≈16 %. Die verbleibende ≈1,2σ-Spannung zwischen dem durch primordiales D/H beobachteten Ω_{b}h^{2} und den Messungen des kosmischen Mikrowellenhintergrunds bleibt bestehen und unterstreicht den Bedarf nach verbesserten dd-Reaktionsraten und mögliche Hinweise auf neue Physik jenseits des Standardmodells der Kosmologie.

    abstract = "We report on a high-precision measurement of the D(γ,n)p photodisintegration reaction at the newly commissioned Shanghai Laser Electron Gamma Source, employing a quasimonochromatic γ-ray beam from Laser Compton Scattering. The cross sections were determined over E\_{γ}=2.327-7.089 MeV, achieving up to a factor of 2.2 improvement in precision near the neutron separation threshold. Combined with previous data in a global Markov chain Monte Carlo analysis using dibaryon effective field theory, we obtained the unprecedentedly precise p(n,γ)D cross sections and thermonuclear rate, with a precision up to ≈4 times higher than previous evaluations. Implemented in a standard Big Bang nucleosynthesis framework, this new rate decreases uncertainty of the key cosmological parameter of baryon density Ω\_{b}h^{2} by up to ≈16\% relative to the Laboratory for Underground Nuclear Astrophysics (LUNA) result. A residual ≈1.2σ tension between Ω\_{b}h^{2} constrained from primordial D/H observations and cosmic microwave background measurements persists, highlighting the need for improved dd reaction rates and offering potential hints of new physics beyond the standard model of cosmology.",

Der Einsatz von Reiserkrankungsdetektoren im Feld bleibt schwierig, da Modelle, die im Labor hochpräzise sind, im Feld häufig schlecht kalibriert sind und nur begrenzte Unsicherheitsabschätzungen liefern, was das Risiko teurer Fehlklassifikationen erhöht. Dieses Papier stellt ein Multi-Objective Big-Bang-Big-Crunch (MO-BBBC)-Framework vor, das sowohl die Erkennung von Reiskrankheiten als auch die Sortenklassifikation gemeinsam durchführt und dabei sechs einsatzorientierte Kriterien optimiert: Klassifizierungsfehler, Kalibrierungsqualität, Unsicherheitsabschätzung, Modellgröße, Inferenzlatenz und Energieverbrauch. Der vorgeschlagene Rahmen beinhaltet bedingte Temperaturskalierung, ein adaptives Verfahren, das eine Überkalibrierung mindert und die Zuverlässigkeit erhält. Das Framework wird in Python auf einem leichten zweiköpfigen Klassifikator implementiert und mit dem Datensatz Paddy Doctor evaluiert; das MO-BBBC-Basisframework erreicht 90,6 % Erkrankungsgenauigkeit und 97,9 % Sortengenauigkeit; verbessert die Kalibrierung auf [Formel: siehe Text] ([Formel: siehe Text] % besser als starke post-hoc Baselines); erzielt einen Micro-AUC von 0,994/0,999 und einen Micro-AP von 0,961/0,994 (Erkrankung/Sorte); liefert robuste OOD-Erkennung (AUROC = 0,887/0,886); und unterstützt Inferenz in Echtzeit bei [Formel: see text] ms und [Formel: see text] ms pro 64er-Batch auf CPU/GPU mit Monte-Carlo-Dropout-Unsicherheit. Das resultierende Pareto-Set ermöglicht es Praktikern, Genauigkeit gegen Effizienz und Zuverlässigkeit abzuwägen und verkleinert die Lücke zwischen Validierung des Prototyps und Feldeinsatz in der Präzisionslandwirtschaft.

    abstract = "Deploying rice disease detectors in the field remains challenging because models that are accurate in the lab are often poorly calibrated and provide limited uncertainty estimates, raising the risk of costly misclassification. This paper proposes a multi-objective Big-Bang Big-Crunch (MO-BBBC) framework that jointly performs disease detection and variety classification while optimizing six deployment-oriented criteria: classification error, calibration quality, uncertainty estimation, model size, inference latency, and energy consumption. The proposed framework presents conditional temperature scaling, an adaptive scheme that mitigates over-calibration and preserves reliability. The framework is implemented in Python on a lightweight two-headed classifier and evaluated on the Paddy Doctor dataset, MO-BBBC base framework achieves 90.6\% disease accuracy and 97.9\% variety accuracy; improves calibration to [Formula: see text] ([Formula: see text]\% better than strong post-hoc baselines); achieves micro-AUC of 0.994/0.999 and micro-AP of 0.961/0.994 (disease/variety); delivers robust OOD detection (AUROC = 0.887/0.886); and supports real-time inference at [Formula: see text] ms and [Formula: see text] ms per 64-sample batch on CPU/GPU with Monte Carlo Dropout uncertainty. The resulting Pareto set enables practitioners to trade accuracy for efficiency and reliability, narrowing the gap between prototype validation and field deployment in precision agriculture.",
