Then, according to these properties and the global continuation method of the zeros of a function depending on one parameter, we derive the existence of odd periodic solutions for all e∈[0,1).

Abstract:

An improvement of the Stokesian Dynamics method for many-particle systems is presented. A direct calculation of the hydrodynamic interaction is used rather than imposing periodic boundary conditions. The two major difficulties concern the accuracy and the speed of calculations. The accuracy discussed in this work is not concerned with the lubrication correction but, rather, focuses on the multipole expansion which until now has only been formulated up to the so-called FTS version or the first order of force moments. This is improved systematically by a real-space multipole expansion with force

To describe the "slow" motions of n interacting mass points, we give the most general four-dimensional (4D) noninstantaneous, nonparticle symmetric Galilei-invariant variational principle. It involves two-body invariants constructed from particle 4-positions and 4-velocities of the proper orthochronous inhomogeneous Galilei group. The resulting 4D equations of motion and multiple-time conserved quantities involve integrals over the worldlines of the other n-1 interacting particles. For a particular time-asymmetric retarded (advanced) interaction, we show the vanishing of all integrals over wor

The method employs successive offset functions combined with a ‘generalized cyclic permutation’ in turn to satisfy the impenetrable boundary condition on each circle.

<strong><em>Problem setting. </em></strong><em>In modern theoretical (as well as in political) discourse, the concept of «identity» is a very popular subject of study of completely different spheres of scientific knowledge - history, philosophy, sociology, pedagogy, psychology, literary studies, etc. The relevance of the study of the problem of identity in the modern world is conditioned by the situation of multiculturalism, the presence of signs ofasynchronous development of the world, the spread of mosaic and multiple identities.

Abstract:

Background Numerous studies have demonstrated the effectiveness of digital interventions for improving the mental health of university students. However, low rates of engagement with these interventions are an ongoing challenge and can compromise effectiveness. Brief, transdiagnostic, web-based video interventions are capable of targeting key mental health and related issues affecting university students and may be more engaging and accessible for this population. Objective This study used a 2-arm randomized controlled trial to evaluate the effectiveness of Uni Virtual Clinic-Lite (UVC-Lite),

Abstract Abstract 808 The growing population of HCT survivors may be at risk for neuropsychological impairment due to exposure to neurotoxic agents. HCT survivors frequently report problems with memory and attention (Cancer 2002;95:183-192), and even though the patients are acutely aware of neuropsychological declines, these changes do not correlate well with impairment on standardized neuropsychological assessments (Bone Marrow Transplant 2005;36:695-702). This discrepancy suggests that the tests may not be sensitive enough to detect subtle changes that could nonetheless impact patients' soci

Abstract:

Background How do we account for the persistent difficulty the U.S. community of science has in educating larger numbers of talented and diverse undergraduates? We posit that the problem lies in the community's unremitting focus on scientific subject matter knowledge and students’ ability to learn, to the neglect of interpersonal social relations—particularly trust. Our study focuses on trust in academic mentoring. This topic is particularly relevant in studies of the undergraduate segment of the pipeline into science that typically occurs in large, impersonal settings that often generate stud

Abstract:

Open water swimming ultra-marathon events ≥10 km have become increasingly popular amongst master athletes. However, very little is known about the timing of training sessions and the impact on sleep. This study aimed to examine sleep behaviours, sleep problems and disorders and the relationship with training timings. This study used a longitudinal observational design for 42 nights with 24 masters' swimmers (n = 13 females), aged 39 ± 11 years, body mass index of 26 ± 3 kg/m2 during a training squad for an ocean ultra-swim (19.7 km) in Western Australia.

Abstract:

We establish a toolbox for studying and applying spin-adapted generalized Pauli constraints (GPCs) in few-electron quantum systems. By exploiting the spin symmetry of realistic N-electron wave functions, the underlying one-body pure N-representability problem simplifies, allowing us to calculate the GPCs for larger system sizes than previously accessible. We then uncover and rigorously prove a superselection rule that highlights the significance of GPCs: whenever a spin-adapted GPC is (approximately) saturated—referred to as (quasi)pinning—the corresponding N-electron wave function assumes a s

Abstract:

We consider the problem of minimizing the relative perimeter under a volume constraint in an unbounded convex body C ⊂ R n C\subset \mathbb {R}^{n} , without assuming any further regularity on the boundary of C C . Motivated by an example of an unbounded convex body with null isoperimetric profile, we introduce the concept of unbounded convex body with uniform geometry. We then provide a handy characterization of the uniform geometry property and, by exploiting the notion of asymptotic cylinder of C C , we prove existence of isoperimetric regions in a generalized sense.

Abstract:

Abstract The influence of a third-body's orbital elements on the second-body's motion in a hierarchical triple system is a crucial problem in astrophysics. Most prolonged evaluation studies have focused on a distant zero-inclined third-body. This study presents a new perspective on orbiter motion equations that addresses a perturbing body in an elliptic orbit derived with consideration of the axial-tilt (obliquity) of the primary. The proposed model is compared by the dual-averaged (DA) method and the N-body problem algorithm. After validation, a generalized three-body model is derived to inve

Abstract:

AbstractIn the planar circular restricted three-body problem and for any value of the mass parameter $$\mu \in (0,1)$$ μ ∈ ( 0 , 1 ) and $$n\ge 1$$ n ≥ 1 , we prove the existence of four families of n-ejection–collision (n-EC) orbits, that is, orbits where the particle ejects from a primary, reaches n maxima in the (Euclidean) distance with respect to it and finally collides with the primary. Such EC orbits have a value of the Jacobi constant of the form $$C=3\mu +Ln^{2/3}(1-\mu )^{2/3}$$ C = 3 μ + L n 2 / 3 ( 1 - μ ) 2 / 3 , where $$L>0$$ L > 0 is big enough but independent of $$\mu $$

Abstract:

Electron–electron interactions and correlations form the basis of difficulties encountered in the theoretical solution of problems dealing with multi-electron systems. Accurate treatment of the electron–electron problem is likely to unravel some nice physical properties of matter embedded in the interaction. In an effort to tackle this many-body problem, a symmetry-dependent all-electron potential generalized for an n -electron atom is suggested in this study. The symmetry dependence in the proposed potential hinges on an empirically determined angular momentum-dependent partitioning fraction
