High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?
Geological Journal, EarlyView.The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

Hamiltonization of Elementary Nonholonomic Systems
, 2015 In this paper, we develop the Chaplygin reducing multiplier method; using this method, we obtain a conformally Hamiltonian representation for three nonholonomic systems, namely, for the nonholonomic oscillator, for the Heisenberg system, and for the ...

Do Financial Analysts Penalize Excessive Growth? Evidence From IPOs
Strategic Change, EarlyView.ABSTRACT This paper investigates the impact of growth rates on analyst recommendations for European firms that underwent an IPO between 2015 and 2020. Drawing from signaling theory, which posits that IPO firms emit signals to the market through their growth rates, we explore how growth in employment and sales influences analysts, who play a key role as

On-Wafer Measurements for Extraction of Effective Dielectric Constant in IC Transmission Lines on Multilayer Substrates [PDF]
Telfor Journal, 2012 Methodology for extracting an effective dielectric constant of microstrip transmission lines on multilayer substrates, from measured or simulated S-parameters data, using on-chip test structures, has been demonstrated.

PERI-OPERATIVE PROTECTIVE ARTIFICIAL PULMONARY VENTILATION IN ABDOMEN SURGERY
Вестник анестезиологии и реаниматологии, 2018 Artificial pulmonary ventilation (APV) is one of the main methods of intensive care, but it differs greatly from natural external respiration and can promote post-operative pulmonary complications (POPC).

Low lying spectrum of weak-disorder quantum waveguides
, 2010 We study the low-lying spectrum of the Dirichlet Laplace operator on a randomly wiggled strip. More precisely, our results are formulated in terms of the eigenvalues of finite segment approximations of the infinite waveguide.

Water availability and land‐use shape the diversity of Odonata in the Middle East
Insect Conservation and Diversity, EarlyView.Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Going Public and the Internal Organization of the Firm
The Journal of Finance, EarlyView.ABSTRACT This paper examines how initial public offerings (IPOs) affect firms' internal organization. We find that IPO firms become more hierarchical and standardized organizations, characterized by additional layers, more managers, smaller control spans, and larger administrative functions. These changes occur mostly in preparation for the IPO and can

The Hess-Appelrot system and its nonholonomic analogs
, 2016 This paper is concerned with the nonholonomic Suslov problem and its generalization proposed by Chaplygin. The issue of the existence of an invariant measure with singular density (having singularities at some points of phase space) is ...
