Abstract:
Recently there has been progress on the calculation of n-point correlation functions with two "heavy" (with large quantum numbers) states at strong coupling. We extend these findings by computing three-point functions corresponding to a folded three-spin semiclassical string with one angular momentum in AdS and two equal spins in the sphere. We recover previous results as limiting cases. Also, following a recent paper by Buchbinder and Tseytlin, we provide relevant four-point functions and consider some of their limits.

Abstract:
It is shown that Weyl spinors in Minkowski space are isomorphic to primary fields of half-integer conformal weights. This yields representations of fermionic two-point functions in terms of correlators of primary fields with a factorized transformation behavior under the Lorentz group. As an application we determine the general structure of the corresponding Lorentz covariant correlators by methods similar to that employed in conformal field theory to determine two- and three-point functions of primary fields. In particular, the chiral symmetry breaking terms resemble fermionic two-point funct

La dualité de N = 4 SYM et la théorie des cordes est un exemple le plus notable de correspondance AdS/CFT. Un des obstacles principaux à l’explorer est le fait que le régime de couplage faible pour la théorie de jauge est le régime de couplage fort pour la théorie des cordes et vice versa.

From the scattering of scalar field near the superradiance region in kerr geometry, the matching of the absorption cross section and the finite-temperature two-point function of dual CFT operator also implies the validity of near-extreme Kerr/CFT correspondence.

Abstract:
AbstractBased on evidence and theory, we state that facilitating and supporting people’s meaning-making processes are health promoting. Hence, meaning-in-life is a salutogenic concept.Authors from various disciplines such as nursing, medicine, psychology, philosophy, religion, and arts argue that the human search for meaning is a primary force in life and one of the most fundamental challenges an individual faces. Research demonstrates that meaning is of great importance for mental as well as physical well-being and crucial for health and quality of life. Studies have shown significant correlations between meaning-in-life and physical health measured by lower mortality for all causes of death; meaning is correlated with less cardiovascular disease, less hypertension, better immune function, less depression, and better coping and recovery from illness. Studies have shown that cancer patients who experience a high degree of meaning have a greater ability to tolerate bodily ailments than those who do not find meaning-in-life. Those who, despite pain and fatigue, experience meaning report better quality-of-life than those with low meaning. Hence, if the individual finds meaning despite illness, ailments, and imminent death, well-being, health, and quality-of-life will increase in the current situation. However, when affected by illness and reduced functionality, finding meaning-in-life might prove more difficult. A will to search for meaning is required, as well as health professionals who help patients and their families not only to cope with illness and suffering but also to find meaning amid these experiences. Accordingly, meaning-in-life is considered a vital salutogenic resource and concept.The psychiatrist Viktor Emil Frankl’s theory of “Will to Meaning” forms the basis for modern health science research on meaning; Frankl’s premise was that man has enough to live by, but too little to live for. According to Frankl, logotherapy ventures into the spiritual dimension of human life. The Greek word “logos” means not only meaning but also spirit. However, Frankl highlighted that in a logotherapeutic context, spirituality is not primarily about religiosity—although religiosity can be a part of it—but refers to a specific human dimension that makes us human. Frankl based his theory on three concepts: meaning, freedom to choose and suffering, stating that the latter has no point. People should not look for an inherent meaning in the negative events happening to them, or in their suffering, because the meaning is not there. The meaning is in the attitude people choose while suffering from illness, crises, etc.

3D point cloud semantic segmentation has attracted wide attention with its extensive applications in autonomous driving, AR/VR, and robot sensing fields. However, in existing methods, each point in the segmentation results is predicted independently from each other.
