Enhanced empirical formulas for α-decay for heavy and superheavy nuclei: Incorporating deformation effects of daughter nuclei

Abstract The latest experimental data of $\alpha$-decay half-lives for 573 nuclei within the range of $52 \leq Z \leq 118$ have been utilized to enhance empirical formulas with updated coefficients. These formulas were enhanced by analyzing the contributions of orbital angular momentum and isospin asymmetry. The effect of deformation of daughter nuclei on the $\alpha$-decay half-life is modeled by incorporating two additional terms, dependent on the quadrupole and hexadecapole deformation parameters, into the empirical formulas for $\alpha$-decay half-lives. Incorporating these deformation-dependent terms, along with angular momentum and isospin asymmetry, improved the standard deviation by approximately $17\%$. The revised empirical formulas for $\alpha$-decay half-lives demonstrated better agreement with experimental data when deformation factors were included. Validation of the modified formulas was conducted through comparisons with recent experimental results and further theoretical predictions. This study presents and compares $\alpha$-decay half-life predictions for several isotopes of superheavy nuclei with $Z = 120-126$, which are yet to be experimentally synthesized. For various isotopes of each element, the variation of $\log_{10} T_{\alpha}$ with changes in neutron number is also explored.

Implications of [formula omitted]-deformed statistics on stellar stability

Examination of Chandrasekhar’s equilibrium and stability condition for stars in the context of q-deformed Maxwell–Boltzmann statistics leads to the derivation of a new analytical formula that extends its classical case. This derivation assumes that the kinetic description of stellar matter conforms to a generalized Maxwell–Boltzmann distribution. It has been found that the maximum allowable radiation pressure at the center of a star for a given mass depends on the deformation parameter q. The classical Chandrasekhar condition is recovered in this framework when q equals 1.

Integrated optimization of turbomachinery via discrete adjoint and hierarchical free form deformation parameterization method

Aerodynamic optimization is an effective technology to improve the performance of turbomachinery. Traditional aerodynamic optimizations often focus on blade profiles and neglect the interactions between the blade and end wall, which may lead to suboptimal optimization result. To address this challenge, this study introduces an integrated optimization framework to simultaneously optimize both the blade and hub end wall aerodynamic shape. A hierarchical free form deformation (FFD) technique is employed to achieve integrated parameterization of the blade and hub, with a total of 580 design variables. To ensure efficient optimization with such a high-dimensional problem, the discrete adjoint method is used, which makes the optimization cycle less than one day. Under the framework, the blade optimization and integrated optimization of a typical compressor fan, rotor37, are conducted. With strict constraints on flow rate and total pressure ratio, the integrated optimization achieves a 2.85% improvement in isentropic efficiency—about 0.6% higher than blade optimization. The flow control mechanisms of two optimization approaches are compared, revealing that both blade optimization and integrated optimization effectively modify the blade profile to weaken the shock wave. Furthermore, by modifying the hub aerodynamic shape to improves the flow structure near the end wall, integrated optimization it is more efficient in turbomachinery aerodynamic optimization.

Analysis of Nuclear Structure Properties and Stellar $\beta$-decay Rates of Even-even 106-120Zr Isotopes.

Abstract The nuclear ground state properties of even-even $^{106-120}$Zr nuclei have been investigated within the framework of the relativistic mean field (RMF) approach. The RMF model with density-dependent DDME2 and DDPC1 interactions is utilized for the calculation of potential energy curves, the nuclear ground-state deformation parameters ($\beta_2$), {neutron} separation energies (S$_n$ and S$_{2n}$) and neutron skin thickness (r$_{np}$) of selected Zr isotopes. Later, the $\beta$-decay properties of Zr isotopes were studied using the proton-neutron {{quasi-particle}} random phase approximation (pn-QRPA) model. These include {Gamow-Teller} (GT) strength distributions, $\beta$-decay half-lives, and stellar electron emission/positron capture rates. The $\beta_{2}$ values computed from the RMF model were employed in the pn-QRPA model as an input parameter for the calculations of $\beta$-decay properties for even-even $^{106-120}$Zr nuclei. The stellar rates were computed {using} the pn-QRPA framework with three different types of deformation parameters. {Only at high temperature (T$_{9}$ $\ge$ $2$) and low density ($\rho Y_e \leq 10^{7}$ g/cm$^3$) values, the sum of electron emission and positron capture rates has a sizeable contribution (with positive exponents) to the stellar rates.

Microstructure, Texture and Mechanical Properties of Magnesium Alloys Processed by Multi-Directional Forging: A Review

Magnesium (Mg) and its alloys are currently the lightest structural metals in engineering applications, widely used in aerospace, defense technology, transportation and electronic 3C fields. Plastic deformation is a commonly used method to improve the comprehensive mechanical properties of Mg alloys. Multi-directional forging (MDF), as a severe plastic deformation (SPD) method, is considered as an effective technology for manufacturing large-sized Mg alloys with high strength and toughness. This paper outlines the process principle of MDF and analyzes the microstructure evolution, texture and mechanical properties of Mg alloys processed by MDF. The effect of deformation parameters, such as deformation temperature, accumulative strain and strain rate, and alloying elements on grain refinement, second phase evolution and texture are discussed systematically. Additionally, recent research highlights the Mg alloys with high strength and toughness processed by MDF. Furthermore, the contribution of grain refinement, precipitation, solid solution and texture-strengthening mechanisms on the mechanical properties are revealed. Finally, we conclude the research progress, analyze the shortcomings in development, and recommend further prospects. We hope this review will inspire new ideas on the development of Mg alloys with a high strength and MDF process.

Seismic performance of inclined discontinuous broken-back block-type gravity quay walls: Numerical investigation and GEP-based modeling

This study explores the seismic performance of discontinuous broken-back block-type gravity quay walls with varying configurations using the finite element method (FEM). For this purpose, plane strain FE meshes are constructed by integrating adaptive meshing and error-based adaptivity techniques. To simulate discontinuities along the wall height and the interaction between the wall and the neighboring medium, interface elements are comprehensively applied between the concrete blocks and between the wall and the surrounding soils. The developed FE models are initially validated against observations from corresponding 1g shaking table tests available in the literature. The primary objective is to evaluate the effectiveness of different inclination angles of the wall body, its base block, and the underlying seabed soil layer in mitigating seismic deformations and lateral earth pressures. FE results reveal that simultaneously inclining the wall body, base block, and seabed layer by 9° significantly reduces permanent horizontal displacement, base sliding, and settlement of the wall. Under a worst-case seismic scenario with a PGA of 0.9g and a frequency of 3 Hz, these deformation parameters decrease by 37.26%, 14.47%, and 48.88%, respectively, compared to the non-inclined quay wall. The suggested mitigation approach improves the overall stability and serviceability of ports and their inland infrastructures during seismic and post-seismic events. This study also develops a predictive polynomial model utilizing Gene Expression Programming (GEP) based on 630 data points derived from validated FE models. The GEP model aims to predict the horizontal displacement of both inclined and non-inclined broken-back block-type quay walls. The novelty of the current research lies in the investigation of inclined configurations as a remediation technique to mitigate deformations and enhance the seismic resilience and performance of broken-back block-type quay walls, utilizing an advanced FE modeling approach. Additionally, a practical machine learning-based model is proposed to estimate the wall's seismic deformations.

Hot deformation behavior and dynamic recrystallization of Ti−3Mo−6Cr−3Al−3Sn titanium alloy

AbstractThe hot compression experiments were performed at a deformation temperature of 720 °C to 870 °C and a strain rate of 0.0005 s−1 to 5 s−1. The strain‐compensated Arrhenius constitutive equation and the hot processing map at a strain of 0.6 were established, and the dynamic recrystallization behaviors of the alloy in different power dissipation (η) regions were studied. The results show that the correlation coefficient (R) and average relative errors (AARE) of the established constitutive equations are 0.999 % and 2.523 % in the β phase region, and 0.988 % and 7.709 % in the α+β phase region, respectively. The hot processing map shows that the deformation parameters in the high power dissipation regions range from 810 °C to 870 °C/0.0005 s−1 to 0.005 s−1, accompanied by a power dissipation factor of 0.41 to 0.55. These regions result from a combination of continuous and discontinuous recrystallization mechanisms. With the decrease in the power dissipation value, the appearance of deformation bands (DBs) and localized flow (FL) in the microstructure increased.

Evaluation of the stress-strain state of the RC beam with the use of DIC

Abstract The article presents the results of adapting the digital image correlation method for the possibility of diagnosing reinforced concrete structures. Reinforced concrete (RC) bending elements are the most widely used in construction practice, which determines the importance of reliable estimation of their stress-strain state. The purpose of this study includes reliable theoretical and experimental investigation of the strength and deformability parameters of the RC beam. The experimental study was conducted using digital image correlation and sub-micron contactless gauges. Experimental data was verified with the calculation of the stress-strain state of the RC beam according to DBN V.2.6-98:2009 and Eurocode 2 and the finite-element modelling (FEM). As a result, the values of deflections, concrete and rebar strains were obtained and presented as corresponding diagrams. The results of all the methods are within the same ranges. Also, the form and character of corresponding diagrams are very similar. The indicated deviations were within acceptable limits. It was noted that the theoretical calculation generally provides lower strain values, which is a satisfactory result, as it indicates the bearing capacity reserves provided by the current regulations. The propagation of cracks was monitored during the experiment and the measured cracks opening was compared with theoretical assumptions. Theoretical values are higher than experimental, which shows certain conservativity of valid normative regulations. The experimental and theoretical results were in good correspondence, which confirms their reliability. It was concluded, that the proposed in the study complex theoretic-experimental approach provides essential information about the strength and deformability of the structure.

Innovative analysis to the time-fractional q-deformed tanh-Gordon equation via modified double Laplace transform method

Abstract In this study, we introduce an efficient analysis of a new equation, termed the time-fractional q q -deformed tanh-Gordon equation (TGE), which is the fractional form of the q q -deformed TGE that was recently introduced by Ali and Alharbi. This equation represents a significant advancement in the field of mathematical physics, which is due to its applications in many fields including superconductivity and fiber optics. It has many applications in condensed matter physics and in modeling physical systems that exhibit violated symmetries. We investigate the q q -deformed TGE in fractional form using Caputo fractional derivative to capture non-local and memory effects, which means they can take into account the entire history of a function rather than just its current value. Notably, this equation has not been previously solved in fractional form, making our approach pioneering in its analysis. We solve this equation utilizing the modified double Laplace transform method, which is considered a semi-analytical technique that combines the double Laplace transform with Adomian polynomials to enable us to extract nonlinear terms. This method renowned for its efficacy in handling fractional differential equations; this is evident from the results obtained in the tables by comparing the analytical solution with the approximate solution we obtained, as well as by calculating the absolute error between them. We examine the existence and the uniqueness of the solution utilizing Schaefer’s fixed-point theorem. Different graphs in 2D and 3D are presented to clarify the effect of different parameters on the behavior of the solution, specially the fractional operator and the deformation parameter q q .

Red Blood Cell Morphology Is Associated with Altered Hemorheological Properties and Fatigue in Patients with Long COVID.

SARS-CoV-2 infection adversely affects rheological parameters, particularly red blood cell (RBC) aggregation and deformability, but whether these changes persist in patients suffering from Long-COVID (LC) and whether these changes are related to RBC morphology remain unknown. Venous blood was collected from n = 30 diagnosed LC patients and n = 30 non-LC controls and RBC deformability, RBC aggregation, and hematological parameters were measured. In addition, RBCs were examined microscopically for morphological abnormalities. The mechanical sensitivity index (MS) was assessed in n = 15 LC and n = 15 non-LC samples. Hematological parameters did not differ between the groups. However, LC showed higher aggregation-related parameters. Although RBC deformability was higher in LC, MS, reflecting the functional capacity to deform, was limited in this group. RBCs from LC showed significantly more morphological abnormalities. The extent of morphological abnormalities correlated with MS and the FACIT-Fatigue score of the LC patients. RBCs from LC show a high degree of morphological abnormalities, which might limit the blood flow determining RBC properties and also be related to fatigue symptomatology in LC. Approaches are now needed to understand the underlying cause of these alterations and to ameliorate these permanent changes.

Assessing coronary artery stenosis exacerbated impact on left ventricular function and deformation in metabolic syndrome patients by 3.0 T cardiac magnetic resonance imaging

BackgroundMetabolic syndrome (MetS) and coronary artery stenosis (CAS) independently increase the risk of cardiovascular events, while the impact of CAS on left ventricular (LV) function and deformation in MetS patients remains unclear. This study investigates how varying degrees of CAS exacerbate LV function and myocardial deformation in MetS patients.MethodsOne hundred thirty-one MetS patients who underwent CMR examinations were divided into two groups: the MetS(CAS−) group (n = 47) and the MetS(CAS+) group (n = 84). The MetS(CAS+) group was divided into MetS with non-obstructive CAS(NOCAS+) (n = 30) and MetS with obstructive CAS(OCAS+) group (n = 54). Additionally, 48 age- and sex-matched subjects were included as a control group. LV functional and deformation parameters were measured and compared among subgroups. The determinants of decreased LV global peak strains in all MetS patients were identified using linear regression. The receiver operating characteristic (ROC) curve and logistic regression model (LRM) evaluated the diagnostic accuracy of the degree of CAS for identifying impaired LV strain.ResultsCompared to MetS(CAS−), MetS(NOCAS+) showed a significantly increased LV mass index (p < 0.05). Global longitudinal peak strain was decreased gradually from MetS(CAS−) through MetS(NOCAS+) to MetS(OCAS+) (− 13.02 ± 2.32% vs. − 10.34 ± 4.05% vs. − 7.55 ± 4.48%, p < 0.05). MetS(OCAS+) groups showed significantly decreased LV global peak strain (GPS), PSSR and PDSR in radial and circumferential directions compared with MetS(NOCAS+) (all p < 0.05). The degree of CAS was independently associated with impaired global radial peak strain (GRPS) (β = − 0.289, p < 0.001) and global longitudinal peak strain (GLPS) (β = 0.254, p = 0.004) in MetS patients. The ROC analysis showed that the degree of CAS can predict impaired GRPS (AUC = 0.730) and impaired GLPS (AUC = 0.685).ConclusionBesides traditional biochemical indicators, incorporating CAS assessment and CMR assessment of the LV into routine evaluations ensures a more holistic approach to managing MetS patients. Timely intervention of CAS is crucial for improving cardiovascular outcomes in this high-risk population.

Cardiac Magnetic Resonance Imaging in the Evaluation of Functional Impairments in the Right Heart.

Cardiac magnetic resonance (cMRI) imaging has recently become essential in cardiology. cMRI is widely recognized as the most reliable imaging technique for assessing the size and performance of the right ventricle. It allows for objective and functional cardiac tissue evaluations. Early in disease progression, cardiac structure and activity decrease subclinically. Late-phase clinically visible signs have been associated with less favourable outcomes. Subclinical alterations ought to be recognized for rapid evaluations and accurate treatment. An increasing amount of evidence supports cMRI deformation parameter quantification. Strain imaging enables cardiologists to assess heart function beyond traditional measurements. Prognostic information for cardiovascular disease patients is obtained through the right ventricle (RV) strain, including information primarily about the left ventricle (LV). Right atrial (RA) function evaluations using RA strain have been promising in recent studies. Therefore, this narrative review aims to present an overview of the data that are currently available for assessing right myocardial strain and biomechanics using cMRI.

Janus deformation of de Sitter space and transitions in gravitational algebras

It is the dS counterpart of the AdS Janus deformation and interpolates two asymptotically dS spaces in the far past and the far future with a single deformation parameter. The Penrose diagram can be elongated along the time direction indefinitely as the deformation becomes large. After studying the classical properties of the geometry such as the area theorem and the fluctuation by a matter field, we explore the algebraic structure of the field operators on the deformed spacetime. We argue that the algebra is a von Neumann factor of type II∞ for small deformations, but there occurs a transition to type I∞ as the deformation increases so that the neck region of the deformed space becomes a Lorentzian cylinder.

Normalization of hot deformation parameters for activation energy analysis in metallic alloys

Abstract Depending on melting point of a given alloy, the temperature range for&amp;#xD;hot deformation of alloys varies widely. Consequently, the apparent activation energy&amp;#xD;of hot deformation, Q, is greatly influenced by the temperature range as well as strain&amp;#xD;rate applied during hot deformation. The purpose of this investigation is to normalize&amp;#xD;hot deformation parameters – temperature and strain rate – to study their effects on&amp;#xD;activation energy. Seventy published hot-deformation data sets were used to investigate&amp;#xD;the effects of normalized hot-deformation variables on Arrhenius-type constitutive&amp;#xD;model parameters. Flow stress, strain rate, and temperature from sample datasets&amp;#xD;were normalized to the range [0, 1] and fitted with an Arrhenius-type model. The&amp;#xD;results showed that, for normalized parameters, the activation energy has exponential&amp;#xD;relationships with a partial derivative of flow stress with strain rate and temperature.

Directional emission with super narrow divergence from perforated elliptical microdisk

In this work, a perforated polymeric elliptical microcavity is investigated by using the finite difference time domain (FDTD) method, highly directional laser emission with a far-field divergence angle of 2.57°, which is achieved without spoiling Q much. Further simulation analyses reveal that the far-field profile is insensitive to the deformation parameter of the hole, demonstrating the device is robust. In addition, the position of the hole and deformation parameter of the elliptical microcavity is vital for optimizing the far-field profile. Our work has provided an effective way to achieve directional whispering gallery mode emission with super narrow divergence, which will be important in integrated optics, optical communication and biochemical sensing.

The Impact of Different Revascularization Strategies Implemented in Acute Myocardial Infarction on the Recovery of Left Ventricular Functional and Deformational Parameters

Background: Despite well-established therapeutic techniques, such as direct revascularization through percutaneous coronary intervention (PCI), acute myocardial infarction (AMI) remains a leading cause of mortality and morbidity. Objectives: To determine if two-dimensional speckle tracking echocardiography (STE) deformation parameters and the early recovery of left ventricular (LV) functions are affected by the timing of PCI in AMI. Methods: A total of 200 cases with newly-onset acute myocardial infarction (AMI) who had a baseline left ventricular ejection fraction (LVEF) higher than 40% and received effective therapy with percutaneous coronary intervention (PCI) were included in this investigation. cases were categorized as either ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI). cases were grouped into four groups according to the time between presentation and PCI. Using standard echocardiography and two-dimensional (2D) ST-elevation STE, individuals were re-evaluated three months later to find out if remodeling had taken place or if the LV function had returned. Results: Of the 200 AMI patients, including 140 males (70%), improvement in global longitudinal strain (GLS) and harmed longitudinal strain (HLS) were better in STEMI and NSTEMI patients received urgent revascularization with PCI (groups I and III) versus patients with pharmacoinvasive strategy or routine invasive strategy (Groups II and IV) (P &lt; 0.05) while there was an insignificant difference between group I and III (P = 0.79). Of the 200 patients, 47 patients (23.5%) presented signs of LV remodeling at 3 months follow up. Age, smoking history, hypertension, dyslipidemia, Killip class, peak creatine phosphokinase - MB level, baseline left ventricular end diastolic volume (LVEDV), HLS, and harmed longitudinal strain rate (HLSR) were all factors that were found to be significantly associated with left ventricular remodeling (P&lt;0.05) in the univariate logistic regression analysis. The following factors were identified as independent predictors of left ventricular remodeling in multivariate logistic regression analysis: damaged left ventricular ejection fraction (EF) and end-systolic volume, peak troponin I, Killip class, culprit left anterior descending (LAD), 2 and 3-vessel coronary artery disease (CAD), and wall motion score index (WMSI). Conclusion: Earlier PCI in AMI helps earlier improvement in myocardial strain parameters. HLS and HLSR are excellent predictors for LV remodeling and may do better than global parameters.

Superstatistical functions of modified shifted Morse potential for diatomic molecules

The application of the molecular potential model to the study of different thermodynamic systems has been a focus of interest in recent time due to its importance in molecular and chemical physics. Hence, the asymptotic iteration method and the Laguerre polynomials are employed to obtain the eigensolutions of the Schrödinger equation with the modified shifted Morse potential model. Vibrational energy results for different diatomic molecules have been presented numerically, and these results are compared with experimental data and other results from available literature. The variation of normalised wave function and probability density of modified shifted Morse potential for some selected diatomic molecules at the ground- and first-excited states have been considered. Results obtained show that the equally spaced sinusoidal wave curves and varying nodes depend on the level of electron concentrations in the diatomic molecules considered. Partition function and other superstatistical function expressions of modified shifted Morse potential for some diatomic molecules within the modified Dirac delta distribution are obtained, using the Poisson summation formula. The superstatistical plots show a high level of dependence on the temperature parameter, maximum vibrational quantum number and deformation parameter. The superstatistical functions for a deformation parameter of zero correspond to the conventional thermodynamic functions.

Effect of Einasto spike on the gravitationally decoupled self-gravitating dark matter halos

Abstract In this work, we consider the possibility of constructing gravitationally bound, charged dark matter halos motivated by Einasto density model. This model generalizes the concept of charged, non-commutative mini-compact objects by including dark matter as its primary component through the principles of the minimal geometric deformation strategy. We point out that the coupling of the non-commutativity inspired Einasto spike density model with a non-isotropic fluid, within the context of gravitational decoupling allows the formation of different minimally deformed dark matter halos, corresponding to each value of the deformation parameter. We assume the Tolman-Kuchowicz cosmological model as a seed metric within the geometric deformation scheme to initially generate an electrically charged isotropic solution. Subsequently, we employ a density-like constraint to produce a second anisotropic charged dark matter stellar model via the Einasto density profile. A complete graphical analysis of the structural variables and stability of both models indicate that, for the considered choice of parameters, both cosmological models are well-behaved, exhibiting expected physical behavior.

Tetrahedral shape and Lambda impurity effect in $^{80}$Zr with a multidimensionally constrained relativistic Hartree-Bogoliubov model

Abstract This study investigates the tetrahedral structure in $^{80}$Zr and Lambda ($\Lambda$) impurity effect in $^{81}_{~\Lambda}$Zr using the multidimensionally constrained relativistic Hartree-Bogoliubov model.&amp;#xD; The ground states of both $^{80}$Zr and $^{81}_{~\Lambda}$Zr exhibit a tetrahedral configuration, accompanied by prolate and axial-octupole shape isomers. &amp;#xD; Our calculations reveal there are changes in the deformation parameters $\beta_{20}$, $\beta_{30}$ and $\beta_{32}$ upon $\Lambda$ binding to $^{80}$Zr, except for $\beta_{32}$ when $\Lambda$ occupies $p$-orbits. &amp;#xD; Compared to the two shape isomers, the $\Lambda$ particle exhibits weaker binding energy in the tetrahedral state when occupying the $1/2^+[000](\Lambda_s)$ or $1/2^-[110]$ single-particle states. In contrast, the strongest binding occurs for the $\Lambda$ particle in the $1/2^-[101]$ state with tetrahedral shape. A large $\Lambda$ separation energy may not necessarily correlate with a significant overlap between the density distributions of the $\Lambda$ particle and the nuclear core, particularly for tetrahedral hypernuclei.

Spatiotemporal Pattern Detection of Ground Deformations Induced by Extreme Rainfall using InSAR EGMS: The case of Cortina d’Ampezzo after Vaia Storm

Abstract. During October 2018 Vaia Storm occurred in the north of Italy, resulting in a huge amount of rainfall that was recorded. The focus here is given to Cortina d’Ampezzo area in the Veneto Region, due to the high importance of the area from touristic and sport perspectives and the presence of landslides. This study is devoted to investigating the impact of the severe sudden rainfall caused by this extreme atmospheric disturbance on the trends of ground deformations over this area, adopting a risk assessment perspective. The ground deformation Time Series (TS) have been derived from the European Ground Motion Service (EGMS) Ortho products derived from Sentinel-1 InSAR data. Then, according to the daily precipitation records and considering the time of this event as a turning temporal point, the TSs of all data points have been divided into pre-event and post-event phases. After obtaining the displacement rates in each phase, the quantified magnitude of changes in the pre-post rates has been calculated through a proposed simple formulation. The spatial distribution of the deformation parameters (i.e., pre-event displacement velocity and change in the pre-post displacement velocities) is found to be a practical tool for gaining comprehensive knowledge regarding the ground deformation and the effect of the extreme weather conditions on the displacement trends over the area. Furthermore, the positioning of the occurrence of deformation parameters has been compared to the landslide inventory of the area. The results showed that the extreme rainfall caused severe acceleration of displacements, more significant in horizontal East-West direction rather than vertical Up-Down direction. Some slight deceleration has been also detected. No initiation (or reactivation) of the stable zones was witnessed, and the portions with high magnitude of pre-event velocities are the ones whose displacement rates have been remarkably modified due to the severe event.
