Published: December 2022

Despite becoming one of the most valuable resources, the role of bamboo in livelihoods and rural development is poorly understood. The present study documents the indigenous utilization pattern of bamboo (Bambusa vulgaris Schrad ex Wendl.) and its significance in the social, cultural and religious life of the people of Bhadrak district, Odisha, India. An exploratory assessment was made from 71 informants through field surveys, literature consultations and key informant interviews. Plant parts such as culms are used for various purposes including construction, handicraft, fencing, musical instruments, as well as in rituals and ceremonies. Leaves are mostly used as fodder. This plant has been instrumental for indigenous people by providing them substantial livelihood through their own indigenous wisdom, from collection to the processing of products. Proper training with modern technology, financial assistance to develop infrastructure, as well as proper marketing of products will encourage more earning opportunities among rural people of the said district.
The Chemotaxonomic Identification Using Structure Types of Secondary Metabolites and Their Bioactivities of Bornean Litophyton arboreum
Authors: Tani Kazuki , Vairappan Charles S.
Published: December 2022

The structure types and bioactivities of secondary metabolites derived from Litophyton arboreum, distributed in Sepanggar Bay, Sabah, Malaysia, were investigated as additional tools for establishing their species identification. As a result, a total of two secondary metabolites (alismol (1) and 10α-methoxy-4β-hydroxy guaian-6-ene (2)) were isolated from Bornean soft coral L. arboreum. Their structures were elucidated based on spectroscopic data analysis and the antifungal activities of compounds 1 and 2 were determined. In addition, the compound 2 showed highest antifungal activity against Haliphthoros milfordensis. As a result of comparison with previous literature, significant variations were observed in relation to structure types of secondary metabolites and bioactivities. Information from this study gives additional evidence of chemotaxonomic significance and baseline data for effective selection of suitable lead pharmaceuticals.
Which Protein Source is Best for Mass-Rearing of Asian Weaver Ants?
Authors: Advento Andreas Dwi , M. Yusah Kalsum , Naim Mohammad , Caliman Jean-Pierre , Fayle Tom Maurice
Published: December 2022

The Asian weaver ant (Oecophylla smaragdina) is sometimes used as a biocontrol agent against pests in tropical agriculture as part of integrated pest management programmes. However, the effectiveness of weaver ants as a predator depends on the abundance and activity of colonies in naturally occurring populations. Mass-rearing is a method that could be useful both for getting lots of colonies and for maximising colony growth and aggressiveness. The diet of mass reared weaver ants potentially impacts their growth rate and behaviour. In this study, we investigate the effect of four common commercial protein diets (mackerel, tuna, cricket and mealworms) on O. smaragdina colony growth and aggressiveness during mass-rearing over a two-month experimental study at the Smart Research Institute, Riau, Indonesia. Colonies fed on mackerel, the cheapest protein source, and mealworm were able to grow significantly larger than those fed on tuna, even though colonies fed with mackerel showed the lowest amount of mass intake of protein food. In contrast, colonies fed with crickets (the diet with the greatest proportion of protein) had the greatest aggression index against experimentally placed bagworms (a common pest in oil palm plantations), with their aggression being significantly greater than that for mackerel-fed colonies. Taken together, our results show that there are trade-offs between different protein diets for weaver ant colonies in mass rearing facilities. Protein diet can be chosen depending on whether colony growth rate, colony aggressiveness, or price is the main factor driving decisions.

Representations of Value Conflict in Iraqi Novel: A Reading of Novel (The Beautiful) By Waarid Bader Al-Salem
Authors: Shukur Houmam Yassin , Naji Suheib Majeed
Published: December 2022

After the ill-fated winds of change blew in 2003, the Iraqi cultural scene witnessed an opening and perhaps a breakdown at all religious, social, and political levels, and new values and customs emerged that entered into conflict with fixed values and customs, as the political change was followed by serious efforts to globalize a certain model of values, aimed at stereotyping the Iraqi self and shaping it according to an ideological line drawn by Western policies seeking to globalize its values and ideas. Based on the above, this study seeks to monitor the value conflicts that exist on the Iraqi scene, especially those that have taken on a religious and social character and contributed in one way or another to the dismantling of the societal structure, the fragmentation and dispossession of the Iraqi self, and the dissolution of national identity. There is what can be called "Americanization", a term commonly used in the field of cultural studies, and refers to the ideological line that seeks to mold peoples and societies in a mold designed by American policy in accordance with its interests and goals.

The role of the foundational learning competence course in preparing English second language students for work integrated learning
Authors:   , Naidoo Veantha
Published: December 2022

The advent of democracy in South Africa has led to the influx of numerous students into the higher education system whose first language is not English. However, the medium of instruction at Higher Education Institutions in South Africa is English. This saw English Second Language (ESL) students being confronted with the challenges of communicating in English during Work-Integrated Learning (WIL). To address these challenges, the Foundational Learning Competence (FLC) course in English was introduced in higher education institutions and became a compulsory module for all first-year students irrespective of their course of study. This study, therefore, specifically explored the experiences of English Second Language students who completed the Foundational Learning Competence course in preparation for WorkIntegrated Learning, to establish its influence in developing their English language and communication that is necessary during Work-Integrated Learning. This study also examined the perspectives of the employers or the WIL coordinators who accept and supervise these students for work-integrated learning, on the English language and communication skills of ESL students who completed the FLC course in English. The researcher utilised a qualitative explorative, descriptive, and contextual research design in this study. Data was generated through individual participant interviews, based at a private higher education institution in the eThekwini Municipality, in the Province of KwaZulu-Natal, South Africa. All participants were selected through purposive sampling techniques and data was analysed according to Creswell’s thematic analytical approach. The overall findings of this study have revealed that the contribution of the FLC course in English to the education of the ESL student is a vital contributor to workplace functioning and efficiency
A cultural studies project : exploring the perceptions of undergraduate media university students on the representations of black gay men in two of South Africa’s leading telenovelas, Uzalo and The Queen
Authors:   , Dube Andile Samuel
Published: December 2022

Even though the South African Constitution protects the rights of LGBTQ+ people and bans discrimination based on sexual orientation, gay people in this country are still victims of the most horrific homophobic abuse and vile discrimination. By venture of its vast reach, the media, television in particular, is an important tool to educate and inform people of the rights of gay people and teach about sexuality. Content creators are responsible for producing the programmes people are exposed to on television, therefore, they are tasked with creating representations of gay people. This study explores the perceptions of media undergraduate students on the representations of black gay people in television, specifically, SABC1’s Uzalo and Mzansi Magic’s The Queen. These two telenovelas have been chosen, because they have black gay characters and are among the most-watched shows on prime-time television. Uzalo has an average of approximately 10 million viewers and The Queen has roughly eight million viewers per episode. The research followed a Cultural Studies approach to explore the role of telenovelas and the active audience paradigm to examine the dynamics of power in the representations of LGBTQ+ on television in South Africa. The study also draws on feminism to highlight the discrimination of the LGBTQ+ community in the African continent. Representation Theory is used as a lead theory in this study, while Social Cognitive Theory is used as a second theory. Two focus groups were held with undergraduate media students from the Journalism Programme and Video Technology Department from the Faculty of Arts and Design in a South African university. Thematic analysis was used to analyse the data from these two focus groups. The study found the visibility of gay people on television has increased over the years. In addition, there are instances where the representation is positive and educational, however, the majority remains negative and relies on stereotypes. These findings indicate the media is a powerful tool that can be used to educate the wider public with regard to marginalised people. Going forward, educational implications of LGBTQ+ persons’ representations need to be considered when represented. Therefore, the study posits that representations on popular culture are important as these telenovelas are part of creating the reality that is lived by the minorities they represent. As such, television does not only represent the world, but it helps in its creation and the audience who watch these telenovelas are co-creators

Authors: Kutlu Aleyna
Published: December 2022

The aim of this paper is to summarize the current state of research on native advertising and its opportunities and limitations for advertisers. Scientific articles, studies and marketing websites are consulted for this purpose. The opportunities and limitations mainly refer to the credibility, advertising impact, positioning and advertising labeling of Native Advertising, as well as Native Advertising in the field of social media marketing. Results show that Native Ads benefit from the credibility of publishers and have a positive advertising impact, as they are usually not recognized as advertising. Moreover, their positioning and labeling influences how they are perceived by Internet users. The difficulty of recognizing native ads as advertising is examined from the perspective of the companies and from an ethical perspective. Furthermore, implications for managers of advertising companies are drawn up in order to make native advertising marketing successful.

Valistuksen auringon alle

Published: December 2022

Artikkelissa analysoidaan nykyisen Pohjois-Karjalan maakunnan alueella 1800-luvun viimeisinä vuosikymmeninä käytyä oppikoulujen perustamiseen, laajentamiseen ja valtiollistamiseen liittynyttä julkista keskustelua. Keskustelu sijoittui ajankohtaan, jolloin suomenkielinen oppikoulujärjestelmä syntyi ja vähitellen laajeni eri puolille maata. Koulutusjärjestelmän kehittäminen liittyi kiinteästi suomalaisuusliikkeen tavoitteisiin ja kansallisvaltion rakentamiseen, mutta varsinainen aloitteellisuus ja toiminta yksittäisten oppikoulujen puolesta tapahtui alue- ja paikallistasolla. Pohjois-Karjalan ensimmäinen ja Suomen toinen suomenkielinen oppikoulu perustettiin Joensuuhun 1865. Artikkeli tarkastelee sitä, millaisena alueen ja valtion suhde näyttäytyy oppikoulukeskustelussa ja miten ajan keskeiset poliittiset käsitteet, kuten kansa, sivistys ja valtio, aineistossa ilmenevät. Lähteenä ovat pohjoiskarjalaisten toimijoiden sanomalehdistössä julkaistut kirjoitukset ja valtiopäivillä pitämät puheenvuorot, joita tulkitaan alueen- ja valtionrakentamisen konteksteissa. Artikkeli osoittaa, että koulutuspolitiikalla oli 1800-luvun jälkipuolella keskeinen merkitys alueellisen itseymmärryksen ja poliittisen tilan muodostumisessa. Tutkimusaluetta sidottiin sivistyksen kautta valtioon ja kansakuntaan etenkin 1870-luvun lopulta lähtien, mutta samalla korostettiin valtion vastuuta koulutusmahdollisuuksien alueellisesti tasapuolisessa kehittämisessä.

El presente artículo tiene como objetivo el evidenciar la generación de CO2 de los sectores que producen los alimentos, considerando la intensidad energética requerida. La metodología utilizada para lograr este objetivo son las tablas Input-Output 2007, 2010 y 2015, las cuales están agrupadas en 43 sectores de la economía, basadas en los cuadros de oferta y utilización del Sistema de Cuentas Nacionales, además de utilizar la base de datos del Banco Mundial elaborada por el Centro de Análisis de Información de Dióxido de Carbono, División de Ciencias Ambientales del Laboratorio Nacional de Oak Ridge y la base de datos de emisiones para la investigación atmosférica global (a partir de aquí EDGAR), producida por el Centro Común para Investigaciones de la Comisión Europea (JRC), para estimar tales emisiones en cada sector. Los resultados concluyen que las emisiones de CO2 vertidas por los subsectores primarios panameños representan apenas el 2.9% para el 2007, 2% para el 2010 y 1.9% para el 2015, producto de la limitada utilización de energéticos derivados del petróleo, cuya tendencia explica también la desarticulación de estos sectores en la economía panameña.

Ecosystem impacts of marine heat waves in the northeast Pacific
Authors: Wyatt Abigale M. , Resplandy Laure , Marchetti Adrian
Published: December 2022

Abstract. Marine heat waves (MHWs) are a recurrent phenomenon in
the northeast Pacific that impact regional ecosystems and are expected to
intensify in the future. Prior work showed that these events, including the
2014–2015 “warm blob”, are associated with widespread surface nutrient declines in the subpolar Alaska Gyre (AG) and the North Pacific Transition Zone (NPTZ) but reduced chlorophyll concentrations in the NPTZ only. Here
we explain the contrast between these two regions using a global
ocean biogeochemical model (MOM6-COBALT) with Argo float and ship-based
observations to investigate how MHWs influence marine productivity. We find
that phytoplankton and zooplankton production respond relatively modestly to
MHWs in both regions. However, differences in the response to seasonal iron
and nitrogen limitation between large (>10 µm) and small
(<10 µm) phytoplankton size classes explain the differences
in ecosystem response to MHWs across the two biomes. During MHWs, reduced
nutrient supply limits large phytoplankton production in the NPTZ (−13 %
annually) but has a limited impact on the already iron-limited large
phytoplankton population in the AG (−2 %). In contrast, MHWs yield a
springtime increase in small phytoplankton in both regions due to shallower
mixed layers and weaker light limitation. These modest changes are in
apparent contradiction with prior estimates suggesting a collapse in net
community production during the warm blob. We show, however, that 70 % of
the decline in net community production previously calculated from nitrate
Argo data can be attributed to artifacts in the method and that only 30 %
can be attributed to interannual variability, in line with our model-based
results. Although modest, the primary production anomalies associated with
MHWs modify the phytoplankton size distribution, resulting in a significant
shift towards small phytoplankton production (i.e., lower large-to-small-phytoplankton ratio) and reduced secondary and export production, especially
in the NPTZ.
Inconvenient Truth and Inductive Risk in Covid-19 Science
Authors: Lichtenstein Eli I.
Published: December 2022

To clarify the proper role of values in science, focusing on controversial expert responses to Covid-19, this article examines the status of (in)convenient hypotheses. Polarizing cases like health experts downplaying mask efficacy to save resources for healthcare workers, or scientists dismissing “accidental lab leak” hypotheses in view of potential xenophobia, plausibly involve modifying evidential standards for (in)convenient claims. Societies could accept that scientists handle (in)convenient claims just like nonscientists, and give experts less political power. Or societies could hold scientists to a higher bar, by expecting them not to modify evidential standards to avoid costs only incidentally tied to error.
Shareholders in the Dutch Eighteenth-Century Atlantic Trade
Authors: Van der Blij Koen
Published: December 2022

This article provides the first quantitative evidence of the indirect benefits of shareholders of the Middelburgse Commercie Compagnie (MCC), a Dutch Atlantic trading company and the biggest slave trader in the eighteenth-century Dutch Republic. MCC shares provided its owners with a preferred status as suppliers and customers of the company. This article focuses on two years, 1725 and 1770, and finds that approximately one third of the MCC shareholders in both years acted as suppliers or customers of the company. The financial incentives of the directors appear to be better aligned with the financial interests of the shareholders in 1770 compared to 1725.
La imitación como categoría de análisis en ceramología protohistórica y clásica
Authors: Adroher Auroux Andrés María , Segura García Maite
Published: December 2022

En este trabajo apostamos por elevar a categoría de análisis el concepto de imitación, aplicado en principio a la ceramología, pero pudiendo ser ampliado al conjunto general de la disciplina arqueológica; entendemos que se trata de identificar el fenómeno y también de explicarlo, puesto que no cabe duda que la imitación, como concepto amplio, es una de las manifestaciones que quedan explícitas, tanto en la expansión cultural, cómo en la de ideas que son los cauces más generalizados en el desarrollo de las sociedades en cuanto conjuntos, y en la formación de los individuos como particularidades. De esta forma proponemos fijar el concepto, caracterizarlo, detectar las evidencias que lo hacen visible al observador, estableciendo formatos de análisis para concretarlo en el registro arqueológico y finalmente, proponer modelos interpretativos que demuestren la extraordinaria versatilidad de esta manifestación y su amplísima fenomenología que alcanza casi cualquier aspecto de la cultura y de su trasmisión.

Mask-wearing and facial emotion recognition: a preliminary analysis of the relevance of depressive symptoms
Authors: Mazzaferro Mateus
Published: December 2022

Depression is a psychiatric condition that impairs the life of millions of people around the globe. Previous research has shown that depressed individuals tend to present deficits in facial emotion perception. For instance, perception accuracy may be reduced and biases in perceived intensity may be enhanced. Mask-wearing practices initiated in response to the COVID-19 pandemic have become a new social norm often enforced by local mandates. Preliminary studies have shown that mask-wearing may impair facial emotion recognition. In this study, we aimed at understanding how facial emotion recognition impairment interacts with depressive symptoms in a sample of German adolescents and adults (N = 91, 56% female, mean age of 32.7 years) by utilizing a mixed-effects linear regression analysis. We found evidence that mask-wearing may be a limiting factor for facial emotion recognition, as well as for emotion intensity ratings. However, a significant association of depressive symptoms with these outcome variables was not detected. Still, larger sample sizes may have the potential to substantiate a trend toward an interaction of depressive symptoms and mask-wearing for the rating of happy faces. Future research should be committed to psychophysiological processes and to improving the quality of the stimulus material.
A STUDY OF INSTITUTIONAL DETERMINATION AND CONSOLIDATION IN PUBLIC INTERNATIONAL LAW - THE CHAGOS CASE
Authors: KAYACAN Derya Nur
Published: December 2022

Located in the middle of the Indian Ocean, the Chagos Archipelago has been subject to a sovereignty dispute between the United Kingdom and its former colony, Mauritius. Before Mauritius gained independence in 1968, the Chagos Archipelago was separated to establish the British Indian Ocean Territory. The main island in the archipelago, Diego Garcia, was leased to the United States and is home to a military base with 3.000 personnel. Mauritius has been challenging the detachment of the Chagos Archipelago, which it claims to be unlawful, by using international legal mechanisms available before it. After a journey that involved the International Court of Justice (ICJ), the United Nations General Assembly (UNGA), and the International Tribunal for the Law of the Sea (ITLOS), Mauritius has achieved legal victory.

The ICJ’s Advisory Opinion determined that Mauritius’s right to self-determination within the context of decolonization was violated and the ITLOS Special Chamber consolidated this finding by acknowledging Mauritius as the sovereign of the Chagos Archipelago. While these decisions are admirable for upholding the right to self-determination, they have stretched the jurisdictional limits of each respective institution by ruling on a sovereignty dispute.

Published: December 2022

After the collapse of the Soviet Union and the end of the Cold War, new challenges and threats of a regional nature emerged. The former Soviet countries decided to sign an agreement on collective security against the backdrop of emerging threats from various terrorist groups and the seizure of power by the Taliban in Afghanistan. This article describes the causes and history of the emergence of the Collective Security Treaty and its transformation into an entire organization. This paper reveals the structure of bodies, competencies, and membership in the CSTO. Within the framework of the Collective Security Treaty and the CSTO charter, this paper explains and analyzes the actions of the CSTO during the adoption and application of forceful decisions. In addition to all the above, the article examines the prospects for development in cooperation between the CSTO and NATO in the status of regional organizations.

Penelitian ini dilakukan untuk melihat tingkat pemaafan keluarga etnis Jawa terhadap narapidana yang mendapatkan program asimilasi pada masa pandemi Covid-19 terkait dengan faktor demografis seperti jenis kelamin, usia, dan tingkat pendidikan. Penelitian ini berfokus pada pendekatan psikologi ulayat, yaitu suatu kajian ilmiah mengenai perilaku dan mental manusia yang bersifat pribumi, tidak dibawa dari daerah lain, dan didesain untuk masyarakatnya sendiri. Responden penelitian ini berjumlah 50 orang keluarga etnis Jawa dari narapidana yang mendapatkan program asimilasi di DKI Jakarta, berjenis kelamin laki-laki dan perempuan, berusia dewasa awal, dewasa menengah, dan dewasa akhir yang dikumpulkan menggunakan teknik purposive sampling. Pengukuran menggunakan skala pemaafan yang disusun oleh Nashori. Analisis data menggunakan distribusi frekuensi dan uji beda. Penelitian ini menemukan dua hasil utama: adanya tingkat pemaafan yang tinggi pada keluarga etnis Jawa terhadap narapidana yang mendapatkan program asimilasi; dan adanya perbedaan tingkat pemaafan ditinjau dari tingkat pendidikan, namun tingkat pemaafan tidak ada perbedaan jika ditinjau dari jenis kelamin dan usia.
Affronting Ocean Models: Submesoscale Interactions between Fronts, Instabilities, and Waves
Authors: Fox-Kemper Baylor
Published: December 2022

Ocean fronts - sharp horizontal gradients in temperature, salinity, and density - are a key feature of the upper ocean that affect the transport of pollutants and the nature of near surface flows. I will highlight some of the recent modeling and theoretical work our group and collaborators have taken on to understand how fronts, frontal instabilities and turbulence, and surface waves interact. Traditional geophysical boundary layer theory neglects horizontal variations, and so is unable to capture frontal dynamics. Some consequences of these features found in large scale modeling and observations of oil, plastics and biological tracer dispersion; boundary layers; fluid energy cycling and dissipation statistics; and finally climate sensitivity will be elucidated.
Nonlinear interaction of the self-sustaining process in the near-wall region of wall-bounded turbulence
Authors: Bae Jane
Published: December 2022

We investigate the nonlinear interaction in the self-sustaining process of wall-bounded turbulence. Resolvent analysis is used to identify the principal forcing (nonlinear) mode which produces the maximum amplification in direct numerical simulations of the minimal channel for the buffer layer. The identified mode is then removed from the nonlinear term of the Navier-Stokes equations at each time step from a direct numerical simulation of a minimal channel. The results show that the removal of the principal forcing mode is able to inhibit turbulence in the buffer layer, while the removal of subsequent modes only marginally affects the flow. Analysis of the dyadic interactions in the nonlinear term shows that contributions toward the principal forcing mode come from a limited number of wavenumber interactions. Using conditional averaging, the flow structures that are responsible for generating the principal forcing mode, and thus the nonlinear interaction to self-sustain turbulence, are identified to be spanwise rolls interacting with meandering streaks.
Toroidal plasmoid generation via extreme hydrodynamic shear
Authors: Gharib Morteza
Published: December 2022

Saint Elmo's fire and lightning are two known forms of naturally occurring atmospheric pressure plasmas. As a technology, non-thermal plasmas are induced from artificially created elecromagnetic or elecrostatic fields. Here we report the observation of arguably a unique case of a naturally formed such plasma created in the air at room temperature without external electromagnetic action, by impinging a high-speed microjet of deionized water on a dielectric solid surface. We demonstrate that tribo-electrification from extreme and focused hydrodynamic shear is the driving mechanism for the generation of energetic free electrons. Air ionization results in a plasma that, unlike the general family, is topologically well defined in the form of a coherent toroidal structure. Possibly confined through its self-induced electromagnetic field, this plasmoid is shown to emit strong luminescence and discrete frequency radio waves. Our experimental study suggests the discovery of a unique platform to support experimentation in low-temperature plasma science.
On the nature of intermittency in a turbulent von Kármán flow
Authors: Faller Hugues
Published: December 2022

We have conducted an extensive study of the scaling properties of small scale turbulence using both numerical and experimental data of a flow in the same von Kármán geometry. We have computed the wavelet structure functions, and the structure functions of the vortical part of the flow and of the local energy transfers. We find that the latter obeys a generalized extended scaling, similar to that already observed for the wavelet structure functions. We compute the multi-fractal spectra of all the structure functions and show that they all coincide with each other, providing a local refined hypothesis. We find that both areas of strong vorticity and strong local energy transfer are highly intermittent and are correlated. For most cases, the location of local maximum of energy transfer is shifted with respect to the location of local maximum of vorticity. We however observe a much stronger correlation between vorticity and local energy transfer in the shear layer, that may be an indication of a self-similar quasi-singular structure that may dominate the scaling properties at large order structure functions.
Analytic solutions for flows through cascades
Authors: Baddoo Peter
Published: December 2022

Motivated by turbomachinery aeroacoustics, we investigate the flow through a periodic array of disconnected objects, termed a “cascade”. We deploy and develop techniques from complex analysis to elucidate the mathematical structures and physical mechanisms relevant to cascade flows. Our approach considers both aerodynamic and aeroacoustic aspects but we focus efforts toward developing conformal mapping techniques amenable to cascades of complicated geometry and topology. The foundation of practical conformal mapping is the Schwarz–Christoffel (SC) formula; we extend the SC formula to periodic domains which enables analytic constructions of the periodic flow field. By utilising tools from function theory, our solutions are valid for an arbitrary number of obstacles per period window.We also present algorithmic advances that enable rapid and accurate calculations of our mappings. Our theory is applied to classical idealised problems such as steady potential flows, unsteady vortex dynamics, and free-streamline flows. These low-order techniques can be used in turbomachinery design schemes or for real-time flow control with data-driven methods.
Topological Origin of Certain Fluid and Plasma Waves
Authors: Marston Brad
Published: December 2022

Symmetries and topology play central roles in our understanding of physical systems. Topology, for instance, explains the precise quantization of the Hall effect and the protection of surface states in topological insulators against scattering from disorder or bumps. However discrete symmetries and topology have so far played little role in thinking about the fluid dynamics of oceans and atmospheres. In this talk I show that, as a consequence of the rotation of the Earth that breaks time reversal symmetry, equatorially trapped Kelvin and Yanai waves emerge as topologically protected edge modes. The non-trivial structure of the bulk Poincaré waves encoded through the first Chern number of value 2 guarantees the existence of these waves. Thus the oceans and atmosphere of Earth naturally share basic physics with topological insulators. As equatorially trapped Kelvin waves in the Pacific ocean are an important component of El Niño Southern Oscillation and other climate oscillations, these new results demonstrate that topology plays a surprising role in Earth’s climate system. We also predict that waves of topological origin will arise in magnetized plasmas. A planned experiment at UCLA’s Basic Plasma Science Facility to look for the waves is described.
