Abstract:

Entertaining the possibility of time travel will invariably challenge dearly-held concepts in fundamental physics. It becomes relatively easy to construct multiple logical contradictions using differing starting points from various well-established fields of physics. Sometimes, the interpretation is that only a full theory of quantum gravity will be able to settle these logical contradictions. Even then, it remains unclear if the multitude of problems could be overcome. Yet as definitive as this seems to the notion of time travel in physics, such recourse to quantum gravity comes with its own,

Abstract:

This article introduces a groundbreaking approach to interstellar travel by drawing an analogy between a nautical manoeuvre called tacking and a proposed technique for traversing vast interstellar distances, that we termed “time tacking.” In sailing, tacking allows a vessel to move against the wind through a series of zig-zag movements. Similarly, in space travel, a comparable manoeuvre will enable spacecraft to navigate the challenges of relativistic time dilation by entering a “mirror universe” and potentially facilitating transitions into other dimensions. This theoretical framework also pr

I give a historical survey of the discussions about the existence of closed timelike curves in general relativistic models of the universe, opening the physical possibility of time travel in the past, as first recognized by K. Gödel in his rotating universe model of 1949. I emphasize that journeying into the past is intimately linked to spacetime models devoid of timelike singularities. Since such singularities arise as an inevitable consequence of the equations of general relativity given physically reasonable assumptions, time travel in the past becomes possible only when one or another of t

The field of quantum gravity struggles with several problems related to time, quantum measurement, nonlocality, and realism. To address these issues, this study develops a 4+1 formalism featuring a flat 4D spacetime evolving with a second form of time, τ, worldlines that locally conserve momentum, and a hypersurface representing the present. As a function of τ, worldlines can spatially readjust and influences can travel backward or forward in the time dimension along these worldlines, offering a physical mechanism for retrocausality.

Abstract:

Huw Price has proposed an argument that suggests a time symmetric ontology for quantum theory must necessarily be retrocausal, i.e. it must involve influences that travel backwards in time. One of Price's assumptions is that the quantum state is a state of reality. However, one of the reasons for exploring retrocausality is that it offers the potential for evading the consequences of no-go theorems, including recent proofs of the reality of the quantum state. Here, we show that this assumption can be replaced by a different assumption, called λ -mediation, that plausibly holds independently of

We propose that the quantum world is not bizarre. QM portrays the wrong universe: the symmetrical one, not the one we inhabit. If quantum waves travel in the oppos

The influence of the noncommutativity on the average speed of a relativistic electron interacting with a uniform magnetic field within the minimum evolution time is investigated.

It is a clear signature of violating Lorentz invariance in the noncommutative relativistic quantum mechanical region.

Abstract:

During the highway reconstruction and expansion, some lanes are often closed on the construction side to ensure that the construction is carried out normally. The presence of the work zone increases the traffic pressure on the construction side of the highway, causing traffic congestion, increased CO2 emissions from motor vehicles, and increasing environmental pollution. The bi-level programming model was developed based on the objective of minimizing the travel time and total CO2 emissions of the system so as to solve it using a quantum particle swarm algorithm with high convergence speed and

Abstract:

No one previously noticed there is a second solution to the equations of Richard Feynman’s Quantum Electrodynamics (QED). It makes identical predictions in the lab. The new solution (Reverse-QED) is closer to nature: it is free of quantum weirdness. For example, it eliminates Schrödinger’s cat. This article is the first time the equations of R-QED have been published. The R-QED amplitude is the negative of Feynman’s amplitude. Because of the Born rule, both amplitude and negative amplitude, when squared, produce the same probability to be tested against empirical data. If you were to measure t

Abstract:

Abstract The traveling salesman problem is the problem of finding out the shortest route in a network of cities, that a salesman needs to travel to cover all the cities, without visiting the same city more than once. This problem is known to be N P -hard with a brute-force complexity of O(N N ) or O(N 2N ) for N number of cities. This problem is equivalent to finding out the shortest Hamiltonian cycle in a given graph, if at least one Hamiltonian cycle exists in it. Quantum algorithms for this problem typically provide with a quadratic speedup only, using Grover’s search, thereby having a comp

Abstract:

Jerzy Limon has always been fascinated by sophisticated aesthetic solutions thanks to which time fl ows differently in the minds of the recipients of stage, visual, audial and literary arts than in life. He shows that on stage, in a radio studio, or in a literary work, time effects can be induced that are the actual subject of quantum physics. In his view, the artistic „calibration” of time not only has an aesthetic value, but also axiological and existential. By experiencing disturbances between the present, the past and the future, we get to know the world, evaluate it, and at the same time

Abstract:

The multiobjective vehicle routing problem considering customer satisfaction (MVRPCS) involves the distribution of orders from several depots to a set of customers over a time window. This paper presents a self-adaptive grid multi-objective quantum evolutionary algorithm (MOQEA) for the MVRPCS, which takes into account customer satisfaction as well as travel costs. The degree of customer satisfaction is represented by proposing an improved fuzzy due-time window, and the optimization problem is modeled as a mixed integer linear program. In the MOQEA, nondominated solution set is constructed by

Abstract:

A new mechanics is developed, extending analytical mechanics by drawing parallels with statistical mechanics. The approach developed replaces the concept of a many-particle system in favor of a “many-observer system” with respect to a single particle in an isotropic and homogeneous universe. Motion is described using the discontinuous quantum motion hypothesis: Space and time changes occur in an alternate and independent fashion. A configuration space is constructed consisting of relative displacements between the particle in question and each “observer.” The results include a description of m

Abstract:

The character of a trip from an origin to a destination is defined by the quasi-utility functions of place utility, trip assessment, and destination expectation. A specific place utility field is determined by a distance minimisation strategy and is generalised for a trip to a destination in any direction with a constant utility. This field is formed by assessing the direction of all trip possibilities and is shown to form rotations with discrete indexes in the psychological domain. The problem is that these trajectories imply that the individual has no memory of past trips, as for stability t

Abstract:

The security of Quantum Secure Direct Communication (QSDC) and its authentication procedure based on multiple stages is analyzed. The security analysis shows that the process of authentication is required to be done three times based on the usage of unitary transformation that is only known between Alice and Bob. In the proposed protocol, a secure quantum handshake is utilized to share the secret polarization angle and an authentication key at the initial stage of authentication over the quantum channel. The symmetry key is used in this work to protect user data communication within the QSDC p

Introduction: R/R FLT3-ITD AML is an aggressive hematologic malignancy with a generally poor prognosis and high relapse rate even after allogeneic hematopoietic stem cell transplantation (HSCT). QuANTUM-R (NCT02039726), a large, global, phase 3, randomized, controlled trial, showed that single-agent quizartinib significantly prolonged overall survival (OS) vs salvage chemotherapy (SC) in patients with R/R FLT3-ITD AML after first-line treatment with or without HSCT (Cortes et al, Lancet Oncol 2019). To evaluate both quality and quantity of life for patients with R/R FLT3-ITD AML, we conducted
