A numerical test of the topographic bias
Journal of Geodetic Science, 2018 In 1962 A. Bjerhammar introduced the method of analytical continuation in physical geodesy, implying that surface gravity anomalies are downward continued into the topographic masses down to an internal sphere (the Bjerhammar sphere).

Quasi-analyticity and analytic continuation—a general principle [PDF]
Transactions of the American Mathematical Society, 1944 1. All the results of this paper are based on a general principle (Theorem I) of an asymptotic character. We show that this theorem leads to results in branches of the theory of functions generally regarded as quite distinct from each other. All the results on Watson's problem, on the theory of quasianalyticity, on one hand, and many known results on ...

Generalized complex time distribution using modified analytical continuation
, 2013 International audienceThe Generalized Complex time distributions have been recently introduced as a way for reducing the auto-terms of any bilinear time-frequency representation that appear when dealing with non-linear time-frequency structures.

The geoid or quasigeoid – which reference surface should be preferred for a national height system?
Journal of Geodetic Science, 2013 Most European states use M. S. Molodensky’s concept of normal heights for their height systems with a quasigeoid model as the reference surface, while the rest of the world rely on orthometric heights with the geoid as the zero-level.

Radar Cross Section Approach in Illusion Effects of Transformation Optics-Based Expander
Frontiers in Materials, 2022 In this paper, analytical calculation has been provided to show illusion perception in electromagnetics expander. For this end, a precise analytical solution has been done for a scattered wave from the expander including an object in the core medium ...

High energy QCD Lipatov’s effective action in Euclidean space
European Physical Journal C: Particles and Fields, 2020 The continuation of high energy QCD Lipatov’s effective action to Euclidean space is performed. The resulting Euclidean QCD RFT action is considered separately in Euclidean “light-cone” coordinates and axial gauge suitable for the numerical and ...

Finite-size effects in one-dimensional Bose–Einstein condensation of photons
Open Physics, 2022 The finite-size effect plays a key role in one-dimensional Bose–Einstein condensation (BEC) of photons since such condensation cannot occur in the thermodynamic limit due to the linear dispersion relation of photons.

On the topographic bias and density distribution in modelling the geoid and orthometric heights
Journal of Geodetic Science, 2018 It is well known that the success in precise determinations of the gravimetric geoid height (N) and the orthometric height (H) rely on the knowledge of the topographic mass distribution.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Gain-scheduling through continuation of observer-based realizations-applications to H∞ and μ controllers [PDF]
, 2000 The dynamic behavior of gain scheduled controllers is highly depending on the state-space representations adopted for the family of lienar controllers designed on a set of operating conditions.
