Summary: The Heisenberg uncertainty principle is connected to the entropic uncertainty principle, and this correspondence is obtained using a Gaussian probability distribution for wave functions associated with the Shannon entropy. Additionally, the Heisenberg uncertainty principle has been extended to a Generalized Uncertainty Principle (GUP) due to quantum gravity effects. In this study, it is shown that GUP has been derived from considering non-extensive entropies proposed by one of the authors. The findings suggest that non-extensive statistics is a signature of quantum gravity.

Summary: The implications of GUP and EUP on a system following the Juttner distribution are investigated in this study, with a focus on deriving the distribution function from the partition function and its relation to thermal energy to ultimately determine the corresponding energy density states.

Summary: This article investigates the (k, a)-generalized wavelet transform in the field of time-frequency signal analysis. Concentration of this transform on sets of finite measure is analyzed, and Donoho-Stark and Benedicks-type uncertainty principles are proven. Several versions of Heisenberg-type uncertainty principles for this transformation are also established. Furthermore, the time frequency and scalogram of this wavelet transform are studied using reproducing kernel and spectral theories. Shapiro's mean dispersion type theorems are provided at the end.

Summary: This article establishes several generalized versions of the invariance principle for describing the long-term dynamical behaviors of discrete-time stochastic dynamical systems based on the typical discrete-time semi-martingale convergence theorem. These principles are suitable for investigating the dynamics in autonomous or non-autonomous systems and their applicability is demonstrated via representative examples. The established principle for autonomous systems allows estimating the time when an orbit, initiating outside a particular bounded set, finally enters it. A generalized version of discrete-time semi-martingale convergence theorem is provided, along with a counterexample highlighting the importance of considering delicate conditions in the use of convergence theorems.

Summary: The existence of a fundamental length scale in nature is predicted by various quantum gravity models. If discovered, it would have significant implications for our understanding of quantum phenomena and may lead to modifications of the Heisenberg uncertainty principle. Despite previous attention, there has not been a common framework for the systematic investigation of generalized uncertainty principles (GUP). In this study, we provide such a framework within the context of nonrelativistic quantum mechanics, based on a few assumptions and simple dimensional analysis.

Summary: A new reduction model technique is proposed to avoid the calibration process in current discrete/lattice methods, allowing for an exhaustive data chart to be built. Parametric analysis using the proper generalized decomposition technique in a lattice beam structure extended the current calibration values and discussed the impact of beam density on connectivity.

Summary: This article introduces a generalized intelligent quality-based approach for fusing multisource information, with the aim of maintaining high quality fused results by considering credible information sources. The method defines vector representation and compatibility criteria for complex-valued distributions, devises an information quality measure using Gini entropy, and proposes uniform and weighted fusion methods for complex-valued distributions. These methods aim to achieve the highest quality fused results by taking into account the credibility of information sources.

Summary: This paper investigates the importance of Jeans mass in the study of nebula collapse and finds that correcting the Jeans mass can better match the theoretical values with the observed values. Three different types of generalized uncertainty principles (GUPs) are used to correct the Jeans mass, and it is found that the Pedram corrected Jeans mass is the closest to the observed value. The impact of temperature and GUP parameters on the corrected Jeans mass is also considered.

Summary: In this paper, a new definition of continuous fractional wavelet transform (MFrWT) in RN is given and some of the basic properties are studied, including the inner product relation and the reconstruction formula. It is also shown that the range of the proposed transform is a reproducing kernel Hilbert space and the associated kernel is obtained. The uncertainty principles of the multidimensional fractional Fourier transform (MFrFT) are obtained, similar to Heisenberg's uncertainty principle, logarithmic uncertainty principle, and local uncertainty principle. Based on these uncertainty principles of MFrFT, the corresponding uncertainty principles, namely Heisenberg's, logarithmic, and local uncertainty principles, are obtained for the proposed MFrWT.

Summary: Single-file diffusion involves particles moving in narrow channels without being able to bypass each other, leading to tracer subdiffusion. The study introduces and provides analytical results for generalized correlation profiles (GCPs) within the frame of the tracer, fully characterizing correlations between the tracer position and bath particles density. The analytical approach offers exact results for GCPs in paradigmatic models of single-file diffusion, highlighting the nonmonotonic dependence with distance to the tracer despite symmetry.

Summary: In this study, we investigate the modifications of quantum entanglement in the generalized uncertainty principle (GUP)-corrected quantum mechanics by considering a coupled harmonic oscillator system. By constructing the ground state ρ(0) and its reduced substate ρ(A) = Tr-B ρ 0, we calculate two entanglement measures, E-EoF(ρ(0)) = S-von(ρ(A)) and E-gamma(ρ(0)) = S-gamma(ρ(A)), where S-von and S-gamma are the von Neumann and Renyi entropies, respectively, up to the first order of the GUP parameter alpha. Our results show that E-gamma(ρ(0)) increases with increasing alpha when gamma = 2, 3, etc. Interestingly, E-EoF(ρ(0)) does not depend on the first order of alpha. Based on these findings, we propose a conjecture regarding the influence of GUP corrections on entanglement, suggesting that E-gamma(ρ(0)) increases or decreases with increasing alpha when gamma > 1 or gamma < 1, respectively, for nonnegative real gamma.
