title: The Basque Summaries Corpus

description: School summaries obtained from Unai Atutxa's thesis (Atutxa, 2022) are available under the CC BY-NC 4.0 license.

A total of 1676 extractions and abstractions have been collected, with 1380 (82.33%) representing monodocument summaries and 296 (17.66%) representing multidocument summaries. From Elementary School, 352 extractions (21% of the total) collected in 2017 are available, all belonging to texts 1, 2, 3, and 4. The majority of the summaries, 1324 (79% of the total), were created by university students. Among university summaries, monodocuments dominate with 1028 (77.64%), of which 303 were collected in 2017 (22.88%) and relate to texts 5, 6, 7, 8, 9, 10, and 11. Additionally, 370 summaries (27.94% of university summaries) were collected in 2018, and 355 in 2019 (26.81%), all corresponding to texts 1, 2, 3, and 4.

Multidocument summaries, totaling 296 (17.66% of the total), were all generated by university students. These were collected over two years, with 230 extracts from the Texts 12 and 13 series compiled in 2020, and 66 summaries of text 12 gathered in 2021.

Orotara 1676na extrakzio eta abstrakzio bildu ditugu; horietatik, 1380 (% 82,33) monodokumentuen laburpenak dira, eta 296 (% 17,66), aldiz, multidokumentuenak. Laburpen batzuk Lehen Hezkuntzako ikasleek burutu dituzte, eta beste batzuk unibertsitateko ikasleek, etorkizunean irakasle izango direnek, alegia. Lehen Hezkuntzako 352 (guztien % 21) laburpen batu ditugu, 2017. urtean batuak, hain zuzen ere; denak dira monodokumentuak, 1-, 2-, 3- eta 4-Testuei dagozkienak. Laburpenik gehientsuenak, 1324 ( guztien % 79), unibertsitatekoak dira; hala ere, bada ezberdintasunik euren artean. Monodokumentuak dira nagusi, 1028 orotara (unibertsitatekoen % 77,64), eta horiek guztiak Compress-eus erabilita egin dituzte ikasleek. 2017an bildu ziren horietako 303 (unibertsitatekoen % 22,88); 5-, 6-, 7-, 8-, 9, 10- eta 11-Testuaren laburpenak dira. 370 laburpen (unibertsitatekoen % 27,94) 2018. urtean bildutakoak dira, eta 2019. urtekoak beste 355 (unibertsitatekoen % 26,81); urte bi horietakoak 1-, 2-, 3-, eta 4-Testuaren laburpenak dira. Bukatzeko, multidokumentuen laburpenak lortu ditugu, 296 (laburpen guztien % 17,66), guztiak unibertsitateko ikasleek eginak. Bi urtetan jaso dira, 2020 eta 2021, biak ala biak Compress-eus erabilita. 2020. urtean 12- eta 13-Testuaren 230 laburpen bildu dira. 2021. urtean, ostera, 12-Testuaren laburpenak dira jasotako guztiak; 66 orotara.

title: Atomic Force Microscopy data of Poly-3-hydroxybutarate and Poly-3-hydroxyvalerate films

description: This dataset consists of atomic force microscopy (AFM) scans of  Polyhydroxyalkanoate films in text (.txt) format as well as their corresponding previews in (.png) format. 

The surfaces of Poly-3-hydroxybutarate (P3HB [100%]) and Poly-3-hydroxyvalerate (P3HB-co-P3HV) [90% :10%]) of six film thicknesses, three scan sizes (5µm, 10µm and 30µm) and three unique scan areas have been scanned with AFM equipment from NT-MDT spectrum instruments.

This dataset has been used in the work *DOI/title of article* within which the scan data has been divided into mutiple sub-pools for experimentation. Details on the structure of the dataset are as follows: 



The (.txt) format of the scanned images can be opened using Gwyddion (gwyddion.net)

For convenience, we show an example of referencing data pools using the Folder Index

E.g. 



With refernce to the article(__), Case 1(a) is a data pool consisting only of scan data from P3HB polymer with all three sizes of data, in this case the reference is written as: (P1,L2) 

Similarly, in case of Case 2(b), which is a data pool consisting of scan data from P3HB and P3HB-co-P3HV polymers with exclusively 30µm scan sizes, the reference is written as: (P1, L2[30]) + (P2, L2[30])


The .txt and .png files have been named using the following nomenculatrue: 

                                                 P_Thickness.N_Area.A_Size.S.txt

                  P – Polymer (P3HB or P3HBV)Thickness.N – Film thickness of the scanned sample (1-6)        Area.A – Scanned area within the film (1-3)          Size.S – Size of the scanned area (5µm,10µm,30µm)

e.g. (P3HB_Thickness.1_Area.1_Size.5.txt)

title: Accounting for Pilot Study Uncertainty in Sample Size Determination of Randomized Controlled Trials

description: A confirmatory randomized controlled trial can be severely underpowered if the variability and/or effect size estimated from a small-scale pilot study is not taken into account in the sample size calculation. This article reviews and summarizes four existing methods and proposes five new approaches, namely a tolerance probability (TP) based approach and four expected power (EP) based approaches. While the TP-based approach takes into account only sampling variability, the four EP-based approaches incorporate both sampling variability and effect size estimates from external pilot studies. Formulas for power and sample size determination of the proposed approaches are first derived for normally distributed response variables and then extended to binary and time-to-event outcome variables. Simulations are conducted to compare the performance of the proposed methods with two existing methods in terms of sample size inflation and total costs (assuming a fixed cost ratio per subject between external pilot and confirmatory trials). The proposed methods are illustrated in two examples, one with binary endpoint and another with time-to-event endpoint, in terms of study sample size and power. Finally, some recommendations are made based on the degree of uncertainty of sampling variance and effect size and the performance of the methods.
