IntroductionIn the majority of Western European countries, the coronavirus
disease (COVID-19) pandemic has led to a dramatic reduction in urooncological surgeries. Our objective was to evaluate the impact of the pandemic on
volume and patterns of urooncological surgery in Poland.Material and methodsThis is a retrospective analysis of 10 urologic centres
in Poland. Data regarding major oncological procedures performed after the
COVID-19 pandemic outbreak (March 15, 2020 – May 31, 2020) were evaluated and compared with data from the respective period in 2019.ResultsBetween March 15, 2020 and May 31, 2020, a total of 968 oncological procedures were performed in participating centres. When compared
to the respective period in 2019 (1063 procedures) the overall number of
surgeries declined by 8.9%. The reduction was observed for transurethral resection of bladder tumour (TURBT) (20.1%) and partial nephrectomies (PN)
(16.5%). Surgical activity considering radical nephrectomy (RN), nephroureterectomy (NU), and radical prostatectomy (RP) remained relatively unchanged, whereas radical cystectomy (RC) burden showed a significant increase (90.9%). Characteristics of
patients treated with TURBT, RC, NU, PN, and RN did not differ significantly between the compared periods,
whereas RP in the COVID-19 period was performed more frequently in patients with a higher grade group
(p = 0.028) and positive digital rectal examination (p = 0.007).ConclusionsSurgical activity for urological cancers in Poland has been maintained during the first wave of
the COVID-19 pandemic. The Polish strategy in the initial period of the COVID-19 crisis mirrors the scenario
of hard initial lockdown followed by adaptive lockdown, during which oncological care remained undisrupted
and did not require particular priority triage.

IntroductionThe purpose of this study was to analyze the risk factors of post-operative atrial fibrillation (POAF) after thoracic surgery, and to build a predictive model for accurate preoperative identification of high-risk patients.Material and methodsIn this study, data of 2072 patients with pulmonary masses and esophageal cancer who attended our hospital in the period from January 1, 2017 to December 31, 2018 were analyzed retrospectively. According to whether AF occurred after the operation, the patients were divided into atrial fibrillation (AF) and non-AF (NAF) groups. The general information (age, sex, height, etc.), previous medical history (chronic lung disease, hypertension, etc.), medication history, preoperative ultrasound and cardiogram results, and preoperative and postoperative electrocardiogram (ECG) were collected. The operation mode, resection scope, histopathology and hospitalization were recorded. Univariate and multivariate logistic regression were used to screen out the risk factors of AF and establish a prediction model.ResultsThe incidence of POAF was 5.98%. Univariate analysis showed that sex, age, body mass index, left atrial diameter and operation organ were the risk factors of POAF. The above factors were included in the multivariate logistic regression analysis, and the results showed that male sex, age, anteroposterior diameter of left atrium and surgical organs were related to POAF. On this basis, a POAF prediction model was constructed, which had good discrimination and calibration. The area under the curve (AUC) is 0.784 with 95% CI: 0.746–0.822.ConclusionsThe prediction model of POAF based on the risk factors selected in this study can accurately predict the occurrence of AF after thoracic surgery.

Abstract. After more than 10 years in orbit, the Soil Moisture and Ocean Salinity (SMOS) European mission is still a unique, high-quality instrument for providing soil moisture over land and sea surface salinity (SSS) over the oceans. At the Barcelona Expert Center (BEC), a new reprocessing of 9 years (2011–2019) of global SMOS SSS maps has been generated. This work presents the algorithms used in the generation of BEC global SMOS SSS product v2.0, as well as an extensive quality assessment. Three SMOS SSS fields are distributed: a high-resolution level-3 product (with DOI https://doi.org/10.20350/digitalCSIC/12601, Olmedo et al., 2020a) consisting of binned SSS in 9 d maps at 0.25∘×0.25∘; low-resolution level-3 SSS computed from the binned salinity by applying a smoothing spatial window of 50 km radius; and level-4 SSS (with DOI https://doi.org/10.20350/digitalCSIC/12600, Olmedo et al., 2020b) consisting of daily 0.05∘×0.05∘ maps that are computed by multifractal fusion with sea surface temperature maps. For the validation of BEC SSS products, we have applied a battery of tests aimed at the assessment of quality of the products both in value and in structure. First, we have compared BEC SSS products with near-to-surface salinity measurements provided by Argo floats. Secondly, we have assessed the geophysical consistency of the products characterized by singularity analysis, and the effective spatial resolutions are also estimated by means of power density spectra and singularity density spectra. Finally, we have calculated full maps of SSS errors by using correlated triple collocation. We have compared the performance of the BEC SMOS product with other satellite SSS and reanalysis products. The main outcomes of this quality assessment are as follows. (i) The bias between BEC SMOS and Argo salinity is lower than 0.02 psu at a global scale, while the standard deviation of their difference is lower than 0.34 and 0.27 psu for the high- and low-resolution level-3 fields (respectively) and 0.24 psu for the level-4 salinity. (ii) The effective spatial resolution is around 40 km for all SSS products and regions. (iii) The results from triple collocation show the BEC SMOS level-4 product as the product with the lowest estimated salinity error in most of the global ocean and the BEC SMOS high-resolution level-3 as the one with the lowest estimated salinity error in regions strongly affected by rainfall and continental freshwater discharge.
Technical note: “Bit by bit”: a practical and general approach for evaluating model computational complexity vs. model performance

Abstract. One of the main objectives of the scientific enterprise is the development of well-performing yet parsimonious models for all natural phenomena and systems. In the 21st century, scientists usually represent their models, hypotheses, and experimental observations using digital computers. Measuring performance and parsimony of computer models is therefore a key theoretical and practical challenge for 21st century science. “Performance” here refers to a model's ability to reduce predictive uncertainty about an object of interest. “Parsimony” (or complexity) comprises two aspects: descriptive complexity – the size of the model itself which can be measured by the disk space it occupies – and computational complexity – the model's effort to provide output. Descriptive complexity is related to inference quality and generality; computational complexity is often a practical and economic concern for limited computing resources. In this context, this paper has two distinct but related goals. The first is to propose a practical method of measuring computational complexity by utility software “Strace”, which counts the total number of memory visits
while running a model on a computer. The second goal is to propose the “bit by bit” method, which combines measuring computational complexity by “Strace” and measuring model performance by information loss relative to
observations, both in bit. For demonstration, we apply the “bit by bit” method to watershed models representing a wide diversity of modelling strategies (artificial neural network, auto-regressive, process-based, and
others). We demonstrate that computational complexity as measured by “Strace” is sensitive to all aspects of a model, such as the size of the model itself, the input data it reads, its numerical scheme, and time stepping. We further demonstrate that for each model, the bit counts for computational complexity exceed those for performance by several orders
of magnitude and that the differences among the models for both computational complexity and performance can be explained by their setup and are in accordance with expectations. We conclude that measuring computational complexity by “Strace” is practical, and it is also general in the sense that it can be applied to any model that can be run on a digital computer. We further conclude that the “bit by bit” approach is general in the sense that it measures two key aspects of a model in the single unit of bit. We suggest that it can be enhanced by additionally measuring a model's descriptive complexity – also
in bit.

Abstract. Mountain glaciers have generally experienced an accelerated retreat over the
last 3 decades as a rapid response to current global warming. However,
the response to previous warm periods in the Holocene is not well-described
for glaciers of the southern Europe mountain ranges, such as the Pyrenees.
The situation during the Medieval Climate Anomaly (900–1300 CE) is
particularly relevant since it is not certain whether the southern European
glaciers just experienced significant ice loss or whether they actually
disappeared. We present here the first chronological study of a glacier
located in the Central Pyrenees (NE Spain), Monte Perdido Glacier (MPG),
carried out by different radiochronological techniques and a comparison with
geochemical proxies from neighbouring palaeoclimate records. The chronological
model evidences that the glacier persisted during the Roman period and the
Medieval Climate Anomaly. The apparent absence of ice in the past
∼ 600 years suggests that any ice accumulated during the
Little Ice Age has since ablated. This interpretation is supported by
measured concentrations of anthropogenic metals, including Zn, Se, Cd, Hg
and Pb, which have concentrations well below those typical of industrial-age ice measured at other glaciers in Europe. This study strengthens the general
understanding that warming of the past few decades has been exceptional for
the past 2 millennia.

Published: March 2021

Pengelolaan limbah dari industri perikanan di Maluku Utara belum optimal dilakukan sehingga menimbulkan dampak yang kurang baik terhadap lingkungan, padahal limbah tersebut dapat diolah lebih lanjut menjadi berbagai produk yang memiliki nilai ekonomis. Limbah pengolahan ikan seperti kepala, tulang, sisik dan kulit biasanya dibuang dan tidak dimanfaatkan oleh masyarakat atau industri perikanan. Limbah yang dihasilkan berupa padatan dan cairan cukup besar pada umumnya berkisar antara 40-50% dari berat total ikan, tergantung jenis ikan yang diolah. Biskuit adalah jenis yang terbuat dari adonan keras melalui proses fermentasi atau pemeraman, berbentuk pipih yang mengarah kepada rasa asin dan relatif renyah, serta bila dipatahkan penampang potongannya berlapis-lapis. Tujuan penelitian ini adalah memanfaatkan limbah ikan cakalang berupa tulang yang akan dijadikan sebagai tepung untuk ditambahkan ke dalam bahan pembuatan biskuit dan untuk mengetahui mutu sensori dari produk biskuit meliputu kenampakan, bau, rasa dan tekstur.

Peramalan cuaca merupakan salah satu faktor penting dalam kehidupan sehari-hari, karena dapat mempengaruhi aktifitas yang dilakukan oleh masyarakat. Peramalan cuaca mengacu pada rangkaian aktivitas yang dilakukan untuk menghasilkan sekumpulan informasi mengenai kondisi cuaca. Salah satu metode yang dapat digunakan dalam memodelkan kondisi-kondisi yang tidak pasti tersebut yaitu dengan rantai markov (Markov Chain). Rantai Markovmerupakan proses acak di mana semua informasi tentang masa depan terkandung di dalam keadaan sekarang. Pada penelitian ini penulis mengggunakan data cuaca harian yang terjadi pada tanggal 12- 18 desember 2017 di Stasiun BMKG Kota Ternate. Data cuaca tersebut didasarkan pada kategori kondisi cuaca Cerah, Berawan, Hujan Ringan dan Hujan, serta kategorikan lagi berdasarkan waktu perubahan cuaca yang terjadi yaitu di pagi hari, siang hari, sore hari dan malam hari. Dari hasil peramalan menggunakan metode rantai markov diperoleh data cuaca harian yang cukup bervariasi, namun cuaca yang paling dominan terjadi dalam satu minggu yaitu hujan ringan dengan probabilitas rata-rata di atas 0,433 atau 43,3% dan hujan dengan probabilitas rata-rata di atas 0,427 atau 42,7%.
