We study the quantum dynamics of a material wavepacket bouncing off a modulated atomic mirror in the presence of a gravitational field. We find the occurrence of coherent accelerated dynamics for atoms. The acceleration takes place for certain initial phase space data and within specific windows of modulation strengths. The realization of the proposed acceleration scheme is within the range of ...

This paper proposes a new method of proton acceleration. A slow plasma wave produced by backward Raman scattering captures slow protons injected. A density gradient of a plasma enables the wave phase velocity to increase as the proton test beams are accelerated. A proof-of-principle experiment is proposed using a T laser and test beams from a Van de Graaff accelerator, in which a 500mJ laser wi...

This study sought to (a) characterize the kinematics aspects of a popular strongman-type event, the heavy sprint-style sled pull, and (b) gain some insight into the kinematic factors that could distinguish the within- and between-subjects' fastest and slowest trials. Six resistance-trained subjects with experience in the heavy sled pull gave informed consent to participate in this study. Subjec...

We present a simple analytical model where the evolution from decelerated to accelerated cosmic expansion can be interpreted as a “first-order” phase transition between two successive stages. The dominant energy condition allows different parts of the universe to evolve, from deceleration to acceleration, at different redshifts within a narrow era. This picture corresponds to the creation of bu...

Abstract. We describe here a new method to increase the peak current of high brightness electron beams as those required to drive X-ray SASE FEL's, that is based on a rectilinear compressor scheme utilizing the bunching properties of slow waves. It is shown that whenever a beam, slower than the synchronous velocity, is injected into a RF wave at the zero acceleration phase and slips back in pha...

High-precision oscillators have significant applications in modern communication and navigation systems, radars, and sensors mounted in unmanned aerial vehicles, helicopters, missiles, and other dynamic platforms. These systems must provide their required performance even when subject to mild to severe dynamic environmental conditions. Oscillators often can provide sufficiently low intrinsic ph...

We present a new physical model that links the maximum speed of light with the minimal Planck scale into a maximal-acceleration Relativity principle in the spacetime tangent bundle and in phase spaces (cotangent bundle). Crucial in order to establish this link is the use of Clifford algebras in phase spaces. The maximal proper-acceleration bound is a = c/Λ in full agreement with the old predict...

WHO 2016 guidelines regarding chronic myeloid leukemia (CML) do not contain groundbreaking changes [1]. Mainly criteria of acceleration phase (AP) identification were revised. Despite these changes, the guidelines are still not standardized and differ significantly, even when compared to guidelines of European Leukemia Net (ELN) [2], International Bone Marrow Transplant Registry (IBMTR) or M. D...

We extend the construction of Born’s Reciprocal Phase Space Relativity to the case of Clifford Spaces which involve the use of polyvectors and a lower/upper length scale. We present the generalized polyvector-valued velocity and acceleration/force boosts in Clifford Phase Spaces and find an explicit Clifford algebraic realization of the velocity and acceleration/force boosts. Finally, we provid...

We develop an acceleration method for material-dominated calculations based on phase-space simplicial interpolation of the relevant material-response functions. This process of interpolation constitutes an approximation scheme by which an exact material-response function is replaced by a sequence of approximating response functions. The terms in the sequence are increasingly accurate, thus ensu...
