Renormalization Group Function

When one uses the Coleman–Weinberg renormalization condition, the effective potential V in the massless [Formula: see text] theory with O(N) symmetry is completely determined by the renormalization group functions. It has been shown how the (p + 1) order renormalization group function determine the sum of all the N p LL order contribution to V to all orders in the loop expansion. We discuss here how, in addition to fixing the N p LL contribution to V, the (p + 1) order renormalization group functions can also be used to determine portions of the N p+n LL contributions to V. When these contributions are summed to all orders, the singularity structure of V is altered. An alternate rearrangement of the contributions to V in powers of ln ϕ, when the extremum condition V′(ϕ = v) = 0 is combined with the renormalization group equation, show that either v = 0 or V is independent of ϕ. This conclusion is supported by showing the LL , …, N 4 LL contributions to V become progressively less dependent on ϕ.

An ideal occlusal scheme plays an important role in a good prognosis of All-on-Four applications, as it does for other implant therapies, due to the potential impact of occlusal loads on implant prosthetic components. The aim of the present three-dimensional (3D) finite element analysis (FEA) study was to investigate the stresses on abutments, screws and prostheses that are generated by occlusal loads via different occlusal schemes in the All-on-Four concept. Three-dimensional models of the maxilla, mandible, implants, implant substructures and prostheses were designed according to the All-on-Four concept. Forces were applied from the occlusal contact points formed in maximum intercuspation and eccentric movements in canine guidance occlusion (CGO), group function occlusion (GFO) and lingualized occlusion (LO). The von Mises stress values for abutment and screws and deformation values for prostheses were obtained and results were evaluated comparatively. It was observed that the stresses on screws and abutments were more evenly distributed in GFO. Maximum deformation values for prosthesis were observed in the CFO model for lateral movement both in the maxilla and mandible. Within the limits of the present study, GFO may be suggested to reduce stresses on screws, abutments and prostheses in the All-on-Four concept.

UNSTRUCTURED Background: Since December 2019, Coronavirus Disease 2019 (COVID-19) emerged in Wuhan city and rapidly spread throughout China. Facing this kind of public health emergency, an efficient, fast and group communication method is needed. Method: As a director of the department Pulmonary and Critical Care Medicine in a tertiary hospitals, which is the only designated one for diagnosis and treatment of COVID-19 in a medium-sized city, I analyzed and summarized the “group function” of WeChat (Weixin, micro-message) App in working about COVID-19. Results: By February 16, 2020, we have completed 1,526 citywide consultations and treatment of 322 inpatients, including 97 patients diagnosed with COVID-19, with the help of 12 WeChat groups by handy. The advantages of WeChat group are as follows: 1. Work efficiency can be improved greatly, saving labor costs. 2. Accurate and intuitive information can be gotten fast and timely, avoiding close contacting with COVID-19 patients. 3. Data and message in WeChat groups can be saved, arranged and reviewed at any time. Conclusions: The “group function” in WeChat App plays a greater role in the public health emergent work about management, diagnosis and treatment of COVID-19.
