    Homogenization of the Schrodinger equation with a time oscillating potential

    Full text link
    We study the homogenization of a Schrodinger equation in a periodic medium with a time dependent potential. This is a model for semiconductors excited by an external electromagnetic wave. We prove that, for a suitable choice of oscillating (both in time and space) potential, one can partially transfer electrons from one Bloch band to another. This justifies the famous "Fermi golden rule" for the transition probability between two such states which is at the basis of various optical properties of semiconductors. Our method is based on a combination of classical homogenization techniques (two-scale convergence and suitable oscillating test functions) and of Bloch waves theory

    Einstein gravity from ANEC correlators

    We study correlation functions with multiple averaged null energy (ANEC) operators in conformal field theories. For large NN CFTs with a large gap to higher spin operators, we show that the OPE between a local operator and the ANEC can be recast as a particularly simple differential operator acting on the local operator. This operator is simple enough that we can resum it and obtain the finite distance OPE. Under the large NN - large gap assumptions, the vanishing of the commutator of ANEC operators tightly constrains the OPE coefficients of the theory. An important example of this phenomenon is the conclusion that a=ca=c in d=4d=4. This implies that the bulk dual of such a CFT is semi-classical Einstein-gravity with minimally coupled matter.Comment: 32 pages + appendices, 6 figures; v2:typos corrected and a comment added in introductio

    Impending carotid blowout stabilization using an LT-D tube

    Adequate stabilization of a patient presenting with a carotid blowout is one of the most challenging issues an on-call ENT surgeon can be confronted with. Reducing the bleeding and securing the airway are essential before more definitive management. We present the case of a 72-year-old patient with head and neck cancer who arrived at the emergency room with a carotid blowout and who was successfully stabilized using a King LT-D ventilation tube

    INSURANCE Insurance Generally: Prohibit Discriminatory Practices; Require Notification of Cancellation, Nonrenewal, or other Termination of Insurance to Certain Persons; Provide Standards and Procedures for Verification of Benefits and Precertifications Relating to Managed Health Benefit Plans; Provide for Liability and Personnel; Include Certain Practices Among Unfair Insurance Practices; Provide for Remedies for Violations

    The Act, titled the Consumers Health Insurance Protection Act, provides that insurers must follow certain procedures when precertifying or verifying enrollee benefits. The Act requires insurers to provide continuity of care to certain individuals in the event they, or a physician, cancels a physician\u27s contract. The Act also makes discrimination based on color, race, religion, and ethnic or national origin in the insurance industry generally an unfair practice. The Act requires insurers to notify enrollees of plan termination, cancellation, or nonrenewal, and of any resulting conversion or continuation rights

    The Act bans video gambling in Georgia by providing that video gambling machines are prohibited gambling devices. The Act also provides examples of bona fide coinoperated amusement machines. The Act also limits the types and amount of prizes that may be awarded for the play of bona fide coin operated amusement machines and mandates that such prizes be awarded on the premises where the device is located

    The effects of self-adherent taping on peak inversion angle and eversion moment upon landing during a maximal vertical jump and a depth drop

    Ankle injuries are the most common injury in physically active adults with roughly 15% to 30% of all physical activity injuries being ankle injuries. The purpose of this study is to evaluate the effectiveness of a self-adherent ankle taping in reducing peak ankle inversion angle and peak ankle eversion moment upon landing during a max vertical jump and depth drop compared to jumping without a prophylactic ankle stabilizer. Twelve volunteers participated in testing procedure on two separate days. Day one consisted of orientation while day two consisted of experimental data collection. The participant’s peak inversion angle and eversion moment were measured using 3D motion capture software and force plates during landing from a maximal vertical jump and depth drop. In support of our hypothesis, peak ankle inversion angle during landing decreased 19% as a result of wearing self-adhesive tape when compared to adhesive tape (p= .002). Additionally, peak inversion angle upon landing from a depth drop was 20% less with self-adherent tape as compared to adhesive tape (p= .018). Despite the differences in peak inversion angles, the subjects experienced nearly identical peak ankle eversion moments during the landing phase of both a vertical jump as well as a depth drop both before and after exercise. In conclusion, self-adherent tape showed promise as an alternative to standard adhesive tape in restricting peak ankle inversion. When comparing self-adhesive tape to adhesive tape, the difference in peak inversion angle remains the only advantage of self-adherent tape found by this study
