Fitting the Cusp Catastrophe in R: A cusp Package Primer
Journal of Statistical Software, 2009 Of the seven elementary catastrophes in catastrophe theory, the “cusp” model is the most widely applied. Most applications are however qualitative. Quantitative techniques for catastrophe modeling have been developed, but so far the limited availability ...

“Hot street” of crime detection in London borough and lockdown impacts
Geo-spatial Information Science, 2023 In recent years, the police intervention strategy “Hot spots policing” has been effective in combating crimes. However, as cities are under the intense pressure of increasing crime and scarce police resources, police patrols are expected to target more ...

Mathematische Nachrichten, 2006 AbstractWe study a construction, which produces surfaces Y ⊂ ℙ3(ℂ) with cusps. For example we obtain surfaces of degree six with 18, 24 or 27 three‐divisible cusps. For sextics in a particular family of surfaces with up to 30 cusps the codes of these sets of cusps are determined explicitly. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Sporadic E Layer with a Structure of Double Cusp in the Vertical Sounding Ionogram
Atmosphere, 2021 In this study, we analyzed a large number of vertical sounding ionograms, obtained by the mid-latitude Cyclone ionosonde (55.85° N; 48.8° E) of Kazan (Volga Region) Federal University, which operates in a rapid-run mode of ionograms (1 ionogram per ...

Unfolding the Cusp-Cusp Bifurcation of Planar Endomorphisms [PDF]
SIAM Journal on Applied Dynamical Systems, 2007 In many applications of practical interest, for example, in control theory, economics, electronics, and neural networks, the dynamics of the system under consideration can be modeled by an endomorphism, which is a discrete smooth map that does not have a uniquely defined inverse; one also speaks simply of a noninvertible map.

Scientific Reports, 2022 Ubiquitination of NEMO by the linear ubiquitin chain assembly complex (LUBAC) is essential for activating the canonical NF-κB signaling pathway. While the NZF1 domain of the HOIP subunit of LUBAC recognizes the NEMO substrate, it is unclear how it ...

Carbon neutral Bhutan: sustaining carbon neutral status under growth pressures
Sustainable Earth Reviews, 2023 Background Bhutan has pledged to remain carbon neutral (CN) in perpetuity. Whether they can sustain this is questionable due to the country’s increasing economic growth (GDP) and commitment to gross national happiness (GNH) outcomes, both of which can ...

Publicacions Matemàtiques, 2009 We consider simple cusp algebras, that is certain subalgebras of the algebra of holomorphic functions on a disk that are annihilated by some distributions living on a singleton. We determine when these algebras can be holized in two dimensions, and when these holizations are globally biholomorphic.

Finding flow: exploring the potential for sustainable fulfilment
The Lancet Planetary Health, 2022 Summary: Materialistic values and lifestyles have been associated with detrimental effects on both personal and planetary health. Therefore, there is a pressing need to identify activities and lifestyles that both promote human wellbeing and protect ...
