Angles in Complex Vector Spaces [PDF]

open access: yesActa Appl.Math.69:95-103,2001, 1999
The article reviews some of the (fairly scattered) information available in the mathematical literature on the subject of angles in complex vector spaces. The following angles and their relations are considered: Euclidean, complex, and Hermitian angles, (Kasner's) pseudo-angle, the Kaehler angle (synonyms for the latter used in the literature are ...

Socio-economic portrait of Polish anglers: implications for recreational fisheries management in freshwater bodies

open access: yesAquatic Living Resources, 2021
Recreational fisheries are an important element of contemporary fisheries. Detailed information about the motivation and opinions of anglers regarding catch-and-release fishing in post-communist countries, such as Poland, has not been widely available to

Angle of incidence [PDF]

open access: yesThe Aeronautical Journal, 1901
If the term ‘angle of incidence’, so frequently used in aeronautical discussions, could be confined to a single definite meaning, viz., the angle at which aeroplane and wind actually meet, much error and confusion would be averted. But many of the best writers use this term loosely and inexactly, with the result that their calculations and explanations

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

“The people’s fish”: Sociocultural dimensions of recreational fishing for Atlantic mackerel in Nova Scotia

open access: yesFrontiers in Marine Science, 2022
Atlantic mackerel or Amalamaq (Scomber scombrus) has been subject to diverse fishing pressures in Atlantic Canada for commercial, bait, recreational, and Indigenous food-social-ceremonial (FSC) fisheries, resulting in its substantial social and cultural ...

The future of wildlife conservation funding: What options do U.S. college students support?

open access: yesConservation Science and Practice, 2021
Insufficient funding is a major impediment to conservation efforts around the world. In the United States, a decline in hunting participation threatens sustainability of the “user‐pay, public benefit” model that has supported wildlife conservation for ...

Behavioural and fitness consequences of direct and indirect non-lethal disturbances in a catch-and-release northern pike (Esox lucius) fishery

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
In a catch-and-release recreational fishery fish populations can be impacted by lethal and sub-lethal effects. In terms of sub-lethal effects anglers may directly (catch-and-release) and/or indirectly (angling-related disturbances, e ...

Sustainability or fun? Recreational angling in Marine Protected Areas

open access: yesOceanological and Hydrobiological Studies, 2022
Gökova Bay MPAs (southern Aegean Sea, Turkey) include six different no-take zones (NTZs: Akyaka, Çamlı, Akbük, Boncuk-Karaca, İngiliz Limanı, Bördübet), in four of which shore angling is permitted (Akyaka, Çamlı, Akbük, Boncuk-Karaca).

On Angles and Pseudo-Angles in Minkowskian Planes [PDF]

open access: yesMathematics, 2018
The main purpose of the present paper is to well define Minkowskian angles and pseudo-angles between the two null directions and between a null direction and any non-null direction, respectively. Moreover, in a kind of way that will be tried to be made clear at the end of the paper, these new sorts of angles and pseudo-angles can similarly to the ...

Model for T2K indication with maximal atmospheric angle and tri-maximal solar angle [PDF]

open access: yesPhys.Rev.D84:053002,2011, 2011
Recently T2K gives hint in favor of large reactor angle. Most of the models, with tri-bimaximal mixing at the leading order, can not reproduce such a large mixing angle since they predict typically corrections for the reactor angle of the order of the Cabibbo angle.
