To date, it is known that tumor cells respond to attacks of T-cells by producing some PD-1/PD-L1 and other connections. Unfortunately, medical methods for preventing these connections are expensive and sometimes non-effective. In this study, we suggest a new way for reducing these connections by producing some noise in the exchanged information between tumor cells, T-cells, hemoglobin, and controller cells such as those of the heart or brain. In this model, we assume that human cells use spinor waves for exchanging information because the velocity of exchanged information between two spinors, which are located a large distance apart, exceeds the velocity of light. In fact, two spinors could send and receive information from each other instantaneously. In this hypothesis, the DNAs within heart cells, brain cells or any controller are built from some spinors such as electrons, and by their motion, some waves are generated. These spinor waves are received by iron atoms and multi-gonal molecules within hemoglobin and other spinors within the blood vessels. The hemoglobin molecules are located on some blood cells, move along the blood vessels and pass on their information to cells, proteins and RNAs. The spins of the spinors within the hemoglobin and also the spins of the charges and ions within the blood vessels are entangled and could transmit any information between cells. Thus, when a tumor is formed, its spinor waves change, and are transmitted rapidly into the heart cells, brain cells and other controller cells. The heart, brain or other controller cells diagnose these quantum waves, and by using the entanglement between the spinors within the blood vessels and the hemoglobin, send some messages to the T-cells. These messages are received by tumor cells and they become ready to respond to attacks. To prevent the reception of information by tumor cells, we can make use of some extra cells or hemoglobin, which interact with spinors and hemoglobin around tumor cells and produce some noise. Science quantum spinor waves are minute and have minor power and intensity; we cannot detect them by our present electronic devices and for this reason, we suggest using biological cells. This is a hypothesis; however, if experiments show its validity, some types of cancers could be cured or controlled by this method. We formulate the model by considering quantum entanglement between spinors within biological systems. By changing any spin within this system, all spins change and consequently, information is transmitted immediately. Then, we add new spinors to this system mathematically, and show that this causes the correlations between the initial spinors to reduce. Thus, the spinors of the extra hemoglobin or cells could act like noise, and prevent reception of real information by tumor cells.

The Open University is a large, distance-learning university, serving all four nations of the United Kingdom (UK) and provides education for most of its students through open entry, meaning that no prior qualifications are necessary. At the OU, we have a low percentage of students who come from a black, Asian or minority ethnic (BAME) background, ranging from 4% to 13% depending on their programme of study. However, due to the high student population at the Open University, that low percentage amounts to thousands of students. We were keen to hear from our BAME students, as we are aware of a challenging awarding gap between these students and white students. We ran three focus groups with a total of ten students from a BAME background, and asked about issues such as being valued, inclusion, a sense of belonging and feeling represented. This was the first time that BAME students had been asked about their views in this way. We found that although there were positive insights, students were uncomfortable engaging in forums, lacked a sense of belonging and did not feel represented in the curriculum. By encouraging these students to give voice to their concerns, we heard, for the first time, some of the issues they are dealing with that need to be addressed.

Local structure of Pd1 single sites on the surface of Pd1In1 intermetallic nanoparticles supported on α-Al2O3 was investigated by the combination of CO-DRIFTS spectroscopy and DFT. CO-DRIFTS spectra of PdIn/Al2O3 catalyst exhibit only one asymmetric absorption band of linearly adsorbed CO comprising two peaks at 2065 and 2055 cm−1 attributable to CO molecules coordinated to Pd1 sites located at (110) and (111) facets of PdIn nanoparticles. The absence of bridged or hollow-bonded CO bands indicates that multipoint adsorption on PdIn nanoparticles is significantly hindered or impossible. DFT results show that on (110) facet multipoint CO adsorption is hindered due to large distance between neighboring Pd atoms (3.35 Å). On (111) facet multipoint CO adsorption on surface palladium atoms is impossible, since adjacent Pd atoms are located below the surface plane.

Abstract We recognize that the spreading of light at large distances (the whole space) is the only property which can decide by yes or no if light really behaves physically like waves, while the fit of the waves for describing the diffraction fringes is insufficient for this purpose. Indeed, the fringe space is too limited and hence, brings the possibility of misinterpretation. Hence, the experiment for the verification if light is spreading like waves at large distances is necessary in principle, and is crucial. However, very surprisingly and tragically, this experiment was totally missing in history. This experiment uses the simplest diffraction case, in which a beam of light falls perpendicularly with its axis on the line and the plane of a straight edge. Practically, this experiment verifies if there is a dependence of the diffracted light at large distances in the geometrical shadow on the changes in beam thickness traversal to a single straight edge, while the distribution of light along the straight edge remains the same. If this dependence exists, as the wave theory for light fundamentally predicts, then the wave approach to light is physically true. If there is no dependence then light cannot behave physically like waves. This experiment can clearly be developed and performed without any calculation from the wave approach, just by a careful measurement practice. However, for a broader view, we describe in detail wave results for spreading of light at large distance, which illustrate the experiment – what are the spatial points where the measurement must be done to see if the above dependence exists, and which is the big picture for the wave approach. We attempted this experiment for many years, but could not finish it because of the lack of resources to measure at 100–500 m. The present article will empower big labs to perform this experiment. However, we show alternatively that the answer to how light spreads also comes from comparing the well known data for the diffraction on macroscopic holes with relatively recent data for the diffraction on nanoscopic holes. This comparison clearly shows that light does not spread physically like waves, which makes necessary a new, non-wave but periodic structure for light. Such an alternative answer regarding the spreading of light also makes absolutely necessary to perform the above missing experiment, as a direct way that convinces anybody how light is spreading.

AbstractIn this paper we prove the existence of a positive energy static solution for the Chern–Simons–Schrödinger system under a large-distance fall-off requirement on the gauge potentials. We are also interested in existence of ground state solutions.

Abstract We argue that strings (vortices) and monopoles are confined, when fields receiving nontrivial Aharonov-Bohm (AB) phases around a string develop vacuum expectation values (VEVs). We illustrate this in an SU(2)×U(1) gauge theory with charged triplet complex scalar fields admitting Alice strings and monopoles, by introducing charged doublet scalar fields receiving nontrivial AB phases around the Alice string. The Alice string carries a half U(1) magnetic flux and 1/4 SU(2) magnetic flux taking a value in two of the SU(2) generators characterizing the U(1) modulus. This string is not confined in the absence of a doublet VEV in the sense that the SU(2) magnetic flux can be detected at large distance by an AB phase around the string. When the doublet field develops VEVs, there appear two kinds of phases that we call deconfined and confined phases. When a single Alice string is present in the deconfined phase, the U(1) modulus of the string and the vacuum moduli are locked (the bulk-soliton moduli locking). In the confined phase, the Alice string is inevitably attached by a domain wall that we call an AB defect and is confined with an anti-Alice string or another Alice string with the same SU(2) flux. Depending on the partner, the pair annihilates or forms a stable doubly-wound Alice string having an SU(2) magnetic flux inside the core, whose color cannot be detected at large distance by AB phases, implying the “color” confinement. The theory also admits stable Abrikosov-Nielsen-Olesen string and a ℤ2 string in the absence of the doublet VEVs, and each decays into two Alice strings in the presence of the doublet VEVs. A monopole in this theory can be constructed as a closed Alice string with the U(1) modulus twisted once, and we show that with the doublet VEVs, monopoles are also confined to monopole mesons of the monopole charge two.

Abstract Microstate geometries in string theory replace the black-hole horizon with a smooth geometric “cap” at the horizon scale. In geometries constructed using superstratum technology, this cap has the somewhat surprising property that induces very large tidal deformations on infalling observers that are far away from it. We find that this large-distance amplification of the tidal effects is also present in horizonless microstate geometries constructed as bubbling solutions, but can be tamed by suitably arranging the bubbles to reduce the strength of some of the gravitational multipole moments. However, despite this taming, these tidal effects still become large at a significant distance from the microstructure. This result suggests that an observer will not fall unharmed into the structure replacing the black hole horizon.

There are many modification of Einstein theory have been established which explain the behavior of universe realistically or hypo-theoretically. Out of those, an f(R) theory of gravity based on non-conformal invariance of gravitational waves has been developed. We attempted to find the solution of this theory for spherically symmetric spacetime in vacuum and compared its result to Einstein theory. We have concluded that solution is consistent with Newtonian limit at large distance from source. Solution predicts two horizon in the spacetime, none of them coincides with Schwarzschild counterpart. However, as this f(R) theory converges to Einstein theory, these horizons coincide.
