391. Generalization ability of feature-based performance prediction models : a statistical analysis across benchmarksAna Nikolikj, Ana Kostovska, Gjorgjina Cenikj, Carola Doerr, Tome Eftimov, 2024, published scientific conference contribution Abstract: This study examines the generalization ability of algorithm performance prediction models across various bench-mark suites. Comparing the statistical similarity between the problem collections with the accuracy of performance prediction models that are based on exploratory landscape analysis features, we observe that there is a positive correlation between these two measures. Specifically, when the high-dimensional feature value distributions between training and testing suites lack statistical significance, the model tends to generalize well, in the sense that the testing errors are in the same range as the training errors. Two experiments validate these findings: one involving the standard benchmark suites, the BBOB and CEC collections, and another using five collections of affine combinations of BBOB problem instances.

394. International Conference The Business of Worldmaking: New Perspectives on Liminal Actors in Postcolonial Development Cooperation : programme and abstracts2024, other monographs and other completed works Abstract: Seeking to move beyond a focus on former colonial Metropoles and Cold War superpowers, and zooming in on peripheral modernization projects, this conference investigates the ‘in-between’ instances of economic cooperation in the self-professed developing countries in Africa, Asia, and South America. The conference primarily focuses on those dynamic players in the postcolonial world which circumvented the habitual East-West and North-South cleavages and presented themselves as: 1) neutral (e.g. Austria, Sweden, Ireland), 2) non-aligned (e.g. Yugoslavia, India, Egypt), 3) pursuing more independent socialist course (e.g. Romania, Cuba, China), 4) allegedly not sharing the colonial past with other Western European nations (e.g. West Germany, Italy), or 5) successfully ‘catching up’ with the most developed nations (e.g. Japan, Israel, South Korea). While not excluding examples of Cold War superpowers and former colonial metropoles’ inserting themselves into this newly emerging multidirectional development consensus the conference focuses on the above described, liminal examples of bilateral collaboration, particularly contributions emphasizing tri- and multilateral efforts between ‘East’, ‘South’ and ‘West’.

395. Izvajanje spremljanja stanja populacij izbranih ciljnih vrst hroščev v letu 2013 in 2014 : Carabus variolosus, Lucanus cervus, Rosalia alpina, Morimus funereus, Osmoderma eremita, Cucujus cinnaberinusAl Vrezec, Špela Ambrožič Ergaver, Andrej Kapla, Irena Bertoncelj, Dejan Bordjan, 2014, final research report Abstract: V končnem poročilu so predstavljeni rezultati terenskih raziskav šestih varstveno pomembnih vrst hroščev v Sloveniji v letih 2013 in 2014. Za močvirskega krešiča (Carabus variolosus), rogača (Lucanus cervus), alpskega kozlička (Rosalia alpina) in bukovega kozlička (Morimus funereus) je v Sloveniji že vzpostavljena shema populacijskega in distribucijskega monitoringa s pripadajočimi metodološkimi protokoli in je pričujoča naloga poročilo o stanju v letih 2013 in 2014 glede na podatke zbrane v okviru populacijskega in distribucijskega monitoringa. Za tri vrste (močvirski krešič, rogač in alpski kozliček) smo izračunali populacijske trende in ugotovili zmeren upad populacije močvirskega krešiča ter stabilni populaciji tako rogača kot alpskega kozlička. Za alpskega in bukovega kozlička smo po zaključku petletnega ciklusa snemanja evalvirali shemo monitoringa in podali predloge izboljšave sheme za nadaljnji monitoring vrst. V poročilu so predstavljeni rezultati popisa v letih 2013 in 2014 za dopolnitev razširjenosti vrste puščavnika (Osmoderma eremita) in škrlatnega kukuja (Cucujus cinnaberinus). Glavni namen pričujoče naloge je bilo tudi testiranje metode lova puščavnika v letu 2014. Poznavanje razširjenosti škrlatnega kukuja (Cucujus cinnaberinus) v zahodni Sloveniji je slabše, zato je bila izvedena dodatna raziskava razširjenosti. Glede na dosedanja vedenja o populacijah vseh že potrjenih vrst hroščev evropskega varstvenega pomena pri nas, podajamo nekaj smernic nujnih raziskav, ki bi jih bilo potrebno iz tega naslova izvesti v Sloveniji. Pri tem smo se osredotočili le na dejansko potrjene vrste.

396. Vzpostavitev in izvajanje monitoringa koščaka (Austropotamobius torrentium) in koščenca (Austropotamobius pallipes) v letih 2014 in 2015 : projekt ʺVzpostavitev in izvajanje monitoringa populacij izbranih ciljnih vrst rakov v letih 2014 in 2015ʺMarijan Govedič, Aleksandra Lešnik, Vesna Grobelnik, Ali Šalamun, Al Vrezec, Martina Jaklič, Špela Ambrožič Ergaver, Andrej Kapla, 2015, final research report Abstract: V okviru naloge “Dodatne raziskave kvalifikacijskih vrst Natura 2000 ter vzpostavitev in izvajanje monitoringa ciljnih vrst rakov v letu 2010 in 2011 (končno poročilo)”, ki jo je po naročilu Ministrstva RS za okolje in prostor izvajal Center za kartografijo favne in flore s sodelovanjem Nacionalnega inštituta za biologijo in zunanjih sodelavcev (Govedič in sod. 2011) je bil predlagan okvirni načrt monitoringa potočnih rakov v Sloveniji. Večji del raziskav je bil takrat opravljen za namene opredelitve novih Natura 2000 območij za koščaka (Austropotamobius torrentium). Večina predlaganih območij iz leta 2011 (Govedič in sod. 2011) je bila v letu 2013 tudi vključena v razširjeno omrežje Natura 2000 (Uradni list RS 33/2013) in kasneje potrjena na Biogeografskem seminarju leta 2014.
V okviru sedanje naloge “Vzpostavitev in izvajanje monitoringa populacij izbranih ciljnih vrst rakov v letih 2014 in 2015” smo izdelali končno metodologijo monitoringa potočnih rakov v Sloveniji, večinoma pa smo sledili predlogu iz leta 2011 (Govedič in sod. 2011). V poročilu so predstavljeni rezultati terenskega dela. Analize populacijskih in distribucijskih trendov še niso mogoče, interpretirali pa smo nekatere izstopajoče rezultate. Glede na prejšnja poročila monitoringa (Govedič in sod. 2007, 2011) smo dopolnili glavne dejavnike ogrožanja potočnih rakov v Sloveniji s predlogi uvedbe nujnega spremljanja v Sloveniji najbolj perečih dejavnikov kot podporo upravljanju območij Natura 2000 za potočne rake.

399. Grapevine flavescence dorée (FD) follow up Vitisens, GRAFDEPI and Qdetect (GRAFDEPI2) : final reportMarina Dermastia, Helga Reisenzein, Luca Ferretti, 2015, final research report Abstract: Europe is the world’s main producer and exporter of grapevine planting material and wine. This important economic sector is facing epidemic threats of at least 10 grapevine yellows diseases (GY) caused by phytoplasmas. In Europe the main phytoplasmas associated with GY are ‘Candidatus’ phytoplasma solani’ (BNp), which is a causal agent of bois noir and FDp, which causes flavescence dorée. Phytoplasmas are notoriously difficult to detect and identify and their specific detection relies exclusively on the molecular methods. Recently new methods, which are reliable, sensitive, fast, less expensive and suitable for using onsites, have been introduced. Among them is a loop-mediated isothermal amplification (LAMP) method, with several advantages (e.g. low sensitivity to plant extracts inhibitors, speed, robustness, simplicity of use) over the other methods (e.g. the real-time PCR). In a recently finished FP7 project VITISENS, a new LAMP protocols have been developed for specific detection of FDp, however, they have not been tested in the interlaboratories trials. In addition, there is no validated LAMP protocol available for the specific detection of BNp at the moment.
The main objectives of this project were:
(1) Development of new loop-mediated isothermal amplification (LAMP) based protocols for accurate, reliable, fast and affordable diagnostics of ‘Candidatus Phytoplasma solani’ (BNp), which will be applicable in-field
(2) To study new possible hosts plants and insect vectors of phytoplasma FDp.
(3) To organize an interlaboratory test performance study (TPS) to obtain validation parameters for the selected LAMP protocols for BNp, as well as for the LAMP assay for FDp detection developed in the course of the FP7 project VITISENS.
Keywords: phytoplasmas, grapevine yellows diseases, LAMP, real-time PCR
