Extensions for Systems of Conservation Laws [PDF]

Communications in Partial Differential Equations, 2012
Extensions (entropies) play a central role in the theory of hyperbolic conservation laws by providing intrinsic selection criteria for weak solutions. For a given hyperbolic system u_t+f(u)_x=0, a standard approach is to analyze directly the second order PDE system for the extensions.

CBCT Evaluation and Conservative Management of a Large Periapical Lesion Associated with Dens Invaginatus Type II

Case Reports in Dentistry, 2022
This case report illustrated the conservative management of an invaginated type II tooth with a large periapical lesion. This dental malformation is characterized by the complexity of root canal anatomy, which when associated with a periapical lesion ...

Augmented reality-guided endodontics: Minimally invasive access through the prosthesis using AReneto® system – A case series

Journal of Oral Biology and Craniofacial Research
Introduction: Vital tooth preparation for dental prosthesis can lead to apical periodontitis due to factors such as exposed dentinal tubules, poor prosthesis fit, and inadequate oral hygiene. These issues often necessitate root canal treatment.

Evaluation of Surgical Treatment by PHILOS Plate versus Conservative Treatment for Displaced Proximal Humeral Fractures in Elderly patients

SVU - International Journal of Medical Sciences
Background: Proximal humeral fractures account for 5:6% of all adult fractures; according to Neer classification displaced fracture could be two-, three-, and four-part fractures of the proximal humerus.

Mechanisation of Model-theoretic Conservative Extension for HOL with Ad-hoc Overloading

, 2021
Definitions of new symbols merely abbreviate expressions in logical frameworks, and no new facts (regarding previously defined symbols) should hold because of a new definition. In Isabelle/HOL, definable symbols are types and constants. The latter may be

Functional and Radiological Outcomes of Conservative Treatment of Upper Limb Diaphyseal and Metaphyseal Fractures (Humerus, Radius, and Ulna) with Extension Casting

Journal of Orthopaedic Diseases and Traumatology
Background: To manage fractures, either operative or nonoperative techniques are required. If the fracture is significantly displaced or angulated, a closed reduction should be done followed by a period of immobilization with casting or splinting.

Active and Reactive Power Conservative Extension of the Hoashi-Millman Equivalent Circuit

IEEE Access
The Hoashi-Millman theorem states that any two-terminal electrical network formed by multiple parallel branches, each containing a voltage source and its own series impedance, can be replaced by one equivalent two-terminal branch formed by a voltage ...

Conservative Treatment in Tracheobronchial Injuries—An Institutional Report

Surgeries, 2021
Tracheobronchial injuries are rare but potentially high-impact events with significant morbidity and mortality. Common etiologies include blunt or penetrating trauma, often combined with various complex injuries, while iatrogenic injury usually occurs ...

Conservative Extensions in Guarded and Two-Variable Fragments [PDF]

CoRR, 2017
We investigate the decidability and computational complexity of (deductive) conservative extensions in fragments of first-order logic (FO), with a focus on the two-variable fragment FO$^2$ and the guarded fragment GF. We prove that conservative extensions are undecidable in any FO fragment that contains FO$^2$ or GF (even the three-variable fragment ...
