Kota Semarang merupakan salah satu wilayah pesisir yang rentan terhadap fenomena banjir rob. Banjir rob merupakan fenomena di mana air laut masuk dan menggenangi daratan. Banyak faktor yang mampu mempengaruhi terbentuknya banjir rob seperti pasang surut, kenaikan muka air laut, dan dorongan angin kencang yang menghasilkan gelombang tinggi. Tujuan dari inventarisasi kejadian banjir rob ini adalah untuk menentukan faktor dominan banjir rob yang terjadi pada kawasan Kota Semarang. Pada penelitian ini, data tanggal kejadian banjir rob yang terjadi bersumber dari media massa serta data bencana alam BPBD Kota Semarang. Data Angin dari European Center for Medium Range Weather Forecast (ECMWF), data curah hujan dari Badan Meteorologi, Klimatologi, dan Geofisika (BMKG), dan data prediksi pasang surut oleh Badan Informasi Geospasial (BIG) juga turut digunakan untuk analisis dalam mengidentifikasi faktor dominan banjir rob. Berdasarkan hasil penelitian, kejadian banjir rob pada Kota Semarang umumnya terjadi pada bulan Desember hingga Februari dan Mei hingga Juli dengan pasang purnama menjadi faktor dominan di musim peralihan 1 dan musim timur dan angin kencang yang diikuti curah hujan tinggi menjadi faktor dominan di musim barat. Kata kunci: Inventarisasi Banjir rob, Semarang, Pasang Surut, Curah Hujan, Angin Abstract Inventory of Tidal Flood Events in Semarang City for the Periode 2012-2020 Semarang is one of many coastal areas that are vulnerable to coastal flooding. Coastal flooding is a phenomenon where sea water enters and inundates the land. Many factors influence the formation of coastal flood including tides, rising sea levels, and strong wind that produce high waves. The purpose of this coastal flood inventory is to determine the dominant factor of coastal flood that occurred in Semarang. In this study, the date of the coastal flood that occurred is sourced from the mass media and natural disaster data by BPBD Semarang. Wind data from European Center for Medium Range Weather Forecast (ECMWF), rainfall data from Meteorology, Climatology, and Geophysical Agency (BMKG), and tidal prediction from Geospatial Information Agency (BIG) are also used for analysis in identifying the dominant factor for coastal flooding. Based on the result of the study, coastal flooding in Semarang City generally occurs in December to February and May to July with spring tide become the dominant factor during the first transitional monsoon and the east monsoon and strong winds followed by high rainfall become the dominant factors during the west monsoon.

Published: November 2023

Ikan layang (Decapterus macrosoma) merupakan salah satu jenis ikan pelagis yang banyak di tangkap di perairan Kabupaten Rembang, Jawa Tengah. Hasil tangkapan tersebut menurun sejak tahun 2018 hingga 2020. Penurunan ini dapat disebabkan oleh perubahan kondisi lingkungan yang mempengaruhi kelimpahan sumber makanan ikan layang tersebut. Sebaran suhu permukaan laut (SPL) dan konsentrasi klorofil-a dapat dijadikan sebagai indikator untuk kesuburan suatu perairan. Tujuan dari penelitian ini adalah untuk mengetahui sebaran SPL dan klorofil-a serta mengetahui pengaruh SPL dan klorofil-a terhadap hasil tangkapan ikan layang di lokasi penelitian, yaitu perairan Kabupaten Rembang. Berdasarkan hasil penelitian menunjukkan bahwa rata-rata SPL di perairan Kabupaten Rembang dari tahun 2018 hingga tahun 2020 adalah 30°C, dan konsentrasi klorofil-a memiliki rata-rata sebesar 1,186 mg/m3. Berdasarkan analisis regresi linier berganda didapat nilai koefisien determinasi (R2) sebesar 0,284672. Nilai ini menunjukkan bahwa SPL dan klorofil-a memiliki pengaruh positif terhadap hasil tangkapan ikan layang di Kabupaten Rembang pada tahun 2018-2020, yakni sebesar 28,47%.Kata kunci: hasil tangkapan, ikan layang, suhu permukaan laut, konsentrasi klorofil-a, koefisien determinasi (R2)AbstractThe shortfin scad fish (Decapterus macrosoma) is one of the pelagic fish that is mostly caught in the waters of Rembang Regency, Central Java. That scad fish catch showed decline trend between year 2018 and year 2020. This declined could be related to environmental conditions change that affect the abundance of scad fish food source. The distribution of sea surface temperature (SST) and the concentration of chlorophyll-a can be used as the indicator for waters productivity. The purpose of this study was to determine the distribution of SST and chlorophyll-a and to find the influence of the SST and chlorophyll-a on the catch of scad fish in the study area. Based on the results, the study showed that the average SST in the waters of Rembang Regency from year 2018 to year 2020 was 30°C and the concentration of chlorophyll-a average was 1.186 mg/m3. Based on multiple linear regression analysis, the R2 value was 0.284672. This value means that SST and chlorophyll-a have a positive influence on the catch of scad fish in Rembang Regency between 2018 and 2020 year, which was 28.47%.Keywords: catch, scad fish, sea surface temperature, chlorophyll-a concentration, coefficient of determination (R2) [Aoh1]Tambahkan metode penelitian dengan singkat [Aoh2]Kata kunci cukup 5 kata dan unik yang dapat mewakili artikel

Authors: Mondello Gabriele , Salvati Manni Riccardo 
Published: November 2023

Abstract
A subvariety of a quasi-projective complex variety X
is called “universally irreducible” if its preimage inside
the universal cover of X is irreducible.
In this paper we investigate sufficient conditions for universal irreducibility.
We consider in detail complete intersection subvarieties of small codimension
inside Siegel moduli spaces of any finite level.
Moreover, we show
that, for

On the standing wave in coupled fractional Klein–Gordon equation
Authors: Guo Zhenyu , Zhang Xin 
Published: November 2023

Abstract
The aim of this paper is to deal with the standing wave problems in coupled nonlinear fractional Klein–Gordon equations. First, we establish the constrained minimizations for a single nonlinear fractional Laplace equation. Then we prove the existence of a standing wave with a ground state using a variational argument. Next, applying the potential well argument and the concavity method, we obtain the sharp criterion for blowing up and global existence. Finally, we show the instability of the standing wave.

Fractal Mellin transform and non-local derivatives
Authors: Khalili Golmankhaneh Alireza , Welch Kerri , Serpa Cristina , Jørgensen Palle E. T. 
Published: November 2023

Abstract
This paper provides a comparison between the fractal calculus of fractal sets and fractal curves. There are introduced the analogues of the Riemann–Liouville and Caputo integrals and derivatives for fractal curves, which are non-local derivatives. Moreover, the concepts analogous to the fractional Laplace operator to address fractal non-local differential equations on fractal curves are defined. Additionally, in the paper it is introduced the fractal local Mellin transform and fractal non-local transform as tools for solving fractal differential equations. The results are supported with tables and examples to demonstrate the findings.

In this paper, we define reproducing kernel Banach space as a space which satisfies this property and the reproducing kernel of it using this relation. We show that this reproducing kernel share a lot of basic properties with the classical one. The notable exception is that in Banach spaces the equality

On June, 2023, Vilnius University Hospital Santaros Klinikos started robotic-assisted operations using VERSIUS robotic surgery system (CMR, Cambridge, UK) and performed 29 robotic surgeries within the first 3 weeks. This surgical system was purchased with funding from the European Regional Development Fund. Comprehensive three-month-long learning courses were organized for a total number of 32 persons, forming 8 independent teams, each consisting of 2 surgeons and 2 nurses. Learning courses consisted of online theoretical training modules, a one-week learning course including technical skills training with a simulator and dry runs as well as cadaveric surgical cases. Furthermore, an additional learning module included dry runs in the operating room prior to the first surgeries, following live and online proctored surgical cases. This enabled a rapid and smooth introduction of the robotic surgical system into clinical practice without putting patients at risk. Abdominal surgeons, urologists, and gynecologists have already performed surgeries using the VERSIUS surgical system and no major complications have been reported. Thoracic surgeons are underway to begin thoracic robotic-assisted surgeries, completing the multidisciplinary VERSIUS surgical system implementation process.
Our goal is to share initial experience with robotic VERSIUS surgical system and evaluate its implementation in Vilnius University Hospital Santaros Klinikos.

Authors: Jurgutavičius Povilas , Juodeikis Žygimantas 
Published: November 2023

Introduction. Sleeve gastrectomy is currently the most popular surgical treatment for obesity worldwide. However, there is still a lack of data on long-term outcomes of this procedure. The objective of this study was to review and analyze the scientific literature and evaluate the long-term (10 years and beyond) results of sleeve gastrectomy for the surgical treatment of obesity. Methods. A literature search was conducted using the PubMed search engine, resulting in 1 443 publications on the long-term results of sleeve gastrectomy for obesity. After applying search criteria and selecting articles by title and abstract, 7 results were included in the systematic review. Results. The included studies involved 2 399 patients after sleeve gastrectomy, with an average age of 41.8 years and 1 577 (65.7%) of all patients being women. The mean preoperative body mass index of the patients in the selected publications was 45.1 kg/m2. Long-term (10 years and beyond) weight loss outcomes were assessed in terms of excess body weight loss. Among the studies, the average excess body weight loss achieved was 54.2%, with a maximum of 70.5% and a minimum of 36%. Arterial hypertension remission was achieved in 23.6%, obstructive sleep apnea remission was achieved in 62.2%, type II diabetes remission was achieved in 54.4%, and dyslipidemia remission was achieved in 42.5% of patients. Conclusion. Sleeve gastrectomy provides a stable reduction in excess body weight and control of comorbidities over 10 years. However, more data on the long-term results of sleeve gastrectomy are needed to compare it with other surgical approaches in the treatment of obesity.

Authors: Melati I Gusti Ayu Prita Sari , Sumada I Ketut 
Published: November 2023

Introduction: Vertigo is an atypical symptom of SDH so that it is sometimes missed for further examination. Given the relatively high mortality of spontaneous SDH, an accurate diagnosis is necessary so that appropriate therapy can be given. This case report presents an elderly man who came with complaints of vertigo.
Case Presentation: A 50-year-old male patient who complained of spinning dizziness and imbalance when walking since three weeks of SMRS. Complaints are felt to come and go, get worse when walking and decrease when you are resting. The results of the physical examination found bilateral SDH in the CT-Scan examination. The patient denied any history of trauma or taking blood thinners so it was considered a spontaneous SDH. Subsequently, the patient was admitted to the hospital for further management. Ten days later there was clinical improvement and the patient continued polyclinical treatment.
Conclusion: Based on this case report, vertigo is one of the non-typical clinical manifestations of SDH that can occur spontaneously.

Latar Belakang: Vertigo merupakan gejala atipikal dari SDH sehingga kadang luput untuk dilakukan pemeriksaan lanjutan. Mengingat mortalitas SDH spontan cukup tinggi, diagnosis yang akurat diperlukan agar terapi yang seusai dapat diberikan. Laporan kasus ini menampilkan seorang laki-laki lansia yang datang dengan keluhan vertigo.
Presentasi kasus: Pasien laki-laki berusia 50 tahun yang mengeluh pusing berputar dan ketidakseimbangan ketika berjalan sejak tiga minggu SMRS. Keluhan dirasakan hilang timbul, memberat saat berjalan dan berkurang saat tengah beristirahat. Pada hasil pemeriksaan fisik ditemukan Ditemukan SDH bilateral dalam pemeriksaan CT-Scan. Pasien menyangkal riwayat trauma atau minum obat pengencer darah sehingga dianggap sebagai SDH spontan. Selanjutnya pasien dirawat di Rumah Sakit untuk tatalaksana lebih lanjut. Sepuluh hari kemudian terdapat perbaikan klinis dan pasien melanjutkan perawatan secara poliklinis.
Simpulan: Berdasarkan pada laporan kasus ini, vertigo adalah salah satu menampilkan manifestasi klinis yang tidak khas SDH dapat terjadi secara spontan.
