Authors: Berlianty Teng , Hetharie Yosia , Putri Anggia
Published: March 2024

This study aims to examine the bambu gila dance as a potential intellectual property for traditional cultural expressions in Maluku which should receive legal protection as part of efforts to defend cultural heritage from claims of ownership by other parties or other countries. Bambu Gila Dance is one of the famous traditional arts from Maluku. The traditional cultural expression in the form of the Bambu Gila dance is expressly protected by the Indonesian intellectual property rights system. However, protection for Bambu Gila Dance as a traditional cultural expression cannot be realized so that it can only be used by other parties illegally. This research is a normative juridical research supported by primary legal materials and secondary legal materials with a conceptual approach and statutory approach. Legal protection for the traditional Bambu Gila dance from Maluku Province has not been effectively implemented, both based on Article 38 of Law Number 28 of 2014 Concerning Copyright, as well as in terms of the actions of government officials who have not been able to inventory traditional dance performance artworks as an expression traditional culture in Maluku including the Bambu Gila Dance. The role of the Provincial and Regency Governments in Maluku is crucial in realizing legal protection for traditional dances, including the Bambu Gila Dance, as intangible cultural heritage through the establishment of regional regulations. These regulations serve as legal basic to provide legal certainty as part of efforts for preventive legal protection for the Bambu Gila Dance.

Authors: Suyanto Suyanto , Nugroho Yusanto , Soendjoto Mochamad Arief
Published: March 2024

Lahan di Desa Kiram merupakan  tanah kering kurang subur, sehingga pertumbuhan tanamannya lambat. Masalah yang dihadapi adalah sulitnya mendapatkan pupuk kimia, karena harganya relatif mahal. Banyaknya limbah organik dari rumah tangga yang belum dimanfaatkan. Sebenarnya limbah tersebut dapat dikonversi menjadi Pupuk Organik Cair (POC) sebagai pengganti pupuk kimia. Pengabdian ini adalah melibatkan kelompok tani Harapan Maju, mata pencaharian mereka sebagai petani Karet, buah – buahan dan tanaman semusim. Hasil pertanian umumnya  untuk konsumsi sendiri, selebihnya dijual. Tujuan pengabdian adalah memperoleh pupuk POC dari limbah rumah tangga seperti: bahan sayuran, buah – buahan dan organik lainnya. Metode yang digunakan adalah praktek langsung. Prinsip pembuatan POC adalah berbasis fermentasi,  yaitu prosesnya berlangsung pada kondisi sedikit atau tanpa oksigen, dengan memanfaatkan mikro organisme. Kelebihan jenis pupuk ini adalah tidak merusak tanah dan tanaman, meskipun digunakan sesering  mungkin. Unsur hara yang terdapat dalam POC lebih mudah diserap oleh akar  tanaman. Hasil pengabdian menunjukkan pupuk POC dapat dipanen pada hari ke-21 proses fermentai. Ember anaerob berkapasitas 20 liter dihasilkan ampas 5,5 liter dan pupuk POC 14,5 liter. Pupuk VOC dapat disimpan untuk digunakan sewaktu – waktu. POC perlu diencerkan dengan perbandingan 1 POC dengan 5-10 air pengencer. Simpulannya adalah peserta antusias  dan mereka merasa  terinspiratif, bahwasanya pengganti pupuk kimia sebenarnya mudah diperoleh dari bahan organik di sekitar tempat tinggalnya.

Published: March 2024

Kegiatan Program Dosen Wajib Mengabdi (PDWA) melalui  Kemitraan Masyarakat umum atau masyarakat non produktif. Tujuan dari kegiatan ini adalah untuk membantu mitra dalam upaya memberikan solusi energi alternatif dan pemanfaatan limbah penggilingan padi di desa Kayu Bawang.. Sebagian besar kebutuhan energi  penduduk pedesaaan adalah untuk sektor rumah tangga dan usaha kecil. Berdasarkan data BPS Kabupaten Banjar tahun 2022, rata-rata produksi padi sawah di Gambut sebesar 39,41 ton/ha dengan luas lahan sawah sekitar 7,673 Ha. Secara otomatis, usaha penggilingan padi marak berada di Gambut, produk dari penggilingan padi akan menghasilkan 20 persen beratnya berupa kulit padi atau sekam. penggilngian padi ini biasanya hanya dibakar menjadi abu gosok atau digunakan menjadi campuran kompos. Pemanfaatan biomassa dengan pembakaran secara langsung tidaklah efektif karena densitas energi yang rendah sehingga biomassa perlu dikonversi dengan cara pemadatan, yang biasanya disebut briket. Selain dapat meningkatkan densitas energi dan kapasitas kalor, briket juga dapat memudahkan dalam penyimpanan dan pengangkutan. Namun briket memiliki kelemahan yaitu agak sulit terbakar saat pertama digunakanMetode yang gunakan adalah studi lapangan, diskusi, pembuatan cetakan briket. Target luaran yang dicapai dari kegiatan pengabdian masyarakat ini adalah produk cetakan briket sekam padi. Dari kegiatan ini dihasilkan produk briket sekam padi yang bisa digunakan sebagai energi alternatif  oleh warga di Desa Kayu Bawang ini. Meskipun nilai kalor briket sekam ini tidak terlalu besar namun pemanfaatan sekam sebagai limbah menjadi bahan bakar alternatif memberikan nilai yang positif.

Authors: Agarwal Kanak , Vijaykrishnan Vedant , Mohanty Dyutit , Murugaiah Manikandan
Published: March 2024

This study presents an extensive collection of data on the aerodynamic behavior at a low Reynolds number and geometric coefficients for 2900 airfoils obtained through the class shape transformation (CST) method. By employing a verified OpenFOAM-based CFD simulation framework, lift and drag coefficients were determined at a Reynolds number of 10^5. Considering the limited availability of data on low Reynolds number airfoils, this dataset is invaluable for a wide range of applications, including unmanned aerial vehicles (UAVs) and wind turbines. Additionally, the study offers a method for automating CFD simulations that could be applied to obtain aerodynamic coefficients at higher Reynolds numbers. The breadth of this dataset also supports the enhancement and creation of machine learning (ML) models, further advancing research into the aerodynamics of airfoils and lifting surfaces.

The Effect of Changing the Nano Size and Crystal Spacing on the Energy Gap and Other Optical and Electrical Properties of BaxFe(1-x)TiO4 Perovskite Cells and Their Theoretical Relations
Authors: Saad Zoalnoon Ahmed
Published: March 2024

Recently perovskite solar cells have been paying attention of researchers. This comes from their high efficiency and stability. In this work, the change of some Optical and Electrical Properties of BaxFe(1-x)TiO4 thin films due to the change of the nanocrystal spacing and size were studied. A simple theoretical model based on the string theory was utilized to explain some of these empirical relations. The empirical results obtained indicated that an increase in the efficiency of the nano solar cell requires the energy gap to be narrow. Decreasing the nanocrystal size and spacing caused the energy gap to become narrower. The energy gap decreases also upon increasing the absorption coefficient and decreasing the transmission. This also requires increasing the conductivity and the magnetic permeability. The increase of the nanocrystal spacing decreases the absorption coefficient, electrical conductivity, and magnetic permeability, while it causes the transmission to increase. All these changes are explained using a simple string model beside Newton's laws. The capability of the string theory to explain this Nano quantum behavior comes from the fact that the string theory, like quantum theory, recognizes both the particle and the wave nature of the Nano system.

Objective: To evaluate the variables influencing the length of stay (LoS) for COVID-19 ICU patients at Tygerberg Hospital (Cape Town) and to identify the covariates that significantly influenced it and any potential risk factors associated with LoS.

Methods and Results: Poisson, negative binomial (NB), Hurdle–Poisson, and
Hurdle–NB regression models were used to model the LoS in this prospective cohort study. The fitted models were compared using the Akaike information criterion (AIC), Vuong’s test criteria, and Rootograms. Based on the chosen performance criteria, the NB model provided the best fit outperforming other candidate models. The baseline LoS count was 8 days. On average, antibiotics reduced LoS by 0.74-fold (95% CI 0.62-0.89) compared to not taking antibiotics. The second wave had a significant effect on the average LoS, which decreased by 0.36-fold (95% CI 0.14-0.93) compared to the first wave. Average LoS increased by 1.01-fold (95% CI 1.01-1.02) for every one-year increase in the age of the patient and by 1.02-fold (95% CI 1.01-1.03) for every 1 unit increase in neutrophils. A 1 ng/L increase in log (TropT) levels decreased the average LoS by 0.87-fold (95% CI 0.81-0.93) similarly, a unit increase in the PF ratio decreased the average LoS by 0.998-fold (95% CI 0.997-0.999) respectively.

Conclusion: The study identified common clinical characteristics associated with length of stay in ICU for COVID-19 patients, including age at admission, PF ratio, neutrophils, TropT, Wave, and antibiotic use. These results can aid in identifying risk factors for increased length of stay, assist in healthcare systems planning, and aid in evaluating different models for analysing this type of data.
Experimental and Numerical Analysis of the Assembling Stresses in Parabolic Leaf Springs for Railway Freight Wagons
Authors: Gomes Vítor M. G. , de Figueiredo Miguel A.V. , Correia José A. F. O. , de Jesus Abílio M. P.
Published: March 2024

Leaf springs are suspension components constituted of several structural and assembly components. Once the leaves are assembled, a stress state due to the assembly process is developed. Thus, the quantification of the assembly stress level should be known in order to be accounted for in the structural design. The aim of this article is precisely to quantify the assembly stress level in parabolic leaf springs for railway freight wagons. An experimental method with the aid of extensometry is considered to evaluate elastic assembly stresses. Next, a numerical model of the leaf spring assembly process with the required boundary conditions is developed to support the experimental results and allow obtaining a distribution of surface stresses along the master leaf length. The development of this work resulted in a surface stress profile along the length of the master leaf generated by the assembly process, where the deviations of the numerical outcomes regarding the analysed spots with strain gauges are mostly of little relevance.
Design of Unmanned Road Width in Open-Pit Mines Based on Offset Reaction Time
Authors: Han Liu , Liu Peng
Published: March 2024

In an effort to enhance the efficiency and safety of open-pit mines, this study explores the optimization of end slope road parameters and slope structures, specifically focusing on unmanned driving lanes.A significant aspect of the study is the development of a truck trajectory offset model, which considers the different reaction times between automated sensors and human drivers in adapting to environmental changes. To test these concepts, the study uses numerical simulations to confirm the stability of the proposed end slope designs. Using Victory West Mine No. 1 as a case study, the research determines the optimized width for unmanned driving lanes and the maximum angle for safe steepening of end slopes. The findings indicate that the optimized unmanned lane width for NTE240 mining dump trucks is 1743 mm, allowing for a 2-degree increase in the slope angle at the south end slope. This optimization leads to a steep mining stripping volume of 3.2735 million m³ and a coal output of 2.49628 million tons, maintaining a stripping ratio of 1.31m³/t. These results demonstrate that the unmanned driving road width optimization not only ensures slope safety but also significantly boosts the economic benefits of steep mining in open-pit mines.

Authors: Hegyi Norbert , Fekete Gusztáv , Jósvai János
Published: March 2024

This article introduces a novel payload structure, which has been experimentally proven to have smaller impact force while the carried internal electronics remains intact. The study describes in details how materials and geometric structures were chosen based on information analysis. It is clarified how possible geometric structures and materials can be chosen to yield optimal efficiency. Finite element method simulations were carried out to investigate the mechanical properties of several geometric structures, which has led to the dodecahedron form. For the frame, Polylactic Acid were chosen as an optimal material. A low air pressure test for parts of the structure, and also the whole structure were carried out with successful results. Drop tests, with force measuring sensors and high speed videos, were carried out for measuring and comparing the maximal impact force of classical payloads and the novel one. Laboratory and real life tests demonstrated that the developed new structure is safer and it is applicable.

Authors: Li Guijiang , Xu Wenze
Published: March 2024

Two interesting compounds such as quaternary ammonium lignin(QAL) and 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (P507) were synthesized as ionic liquids(QP-ILs) for the extraction of metal ions. The extraction behavior of Co(II) and Ni(II) from chloride solution was compared between QP-ILs and P507. The results showed that the extraction rates of Co(II) and Ni(II) in the two solutions varied with the extraction conditions, but QP-ILs has stronger extractability for cobalt than P507, while Ni is on the contrary. Under the same conditions, the Co/Ni separation performance(βCo/Ni) in QP-ILs is superior to that in p507. At pH4.0, 55℃, concentration of 20%, extraction time of 10 minutes, the βCo/Ni of QP-ILs reached to 2703, while that of P507 was only 164. In conclusion, QP-ILs was more efficient than P507 for separating Co from mixed solutions.

Published: March 2024

Robots that learn to perform actions using reinforcement learning to should be able to learn not only static environments, but also environmental changes. Heterogeneous multi-agent reinforcement learning (HMARL) was developed to perform an efficient search, with multiple agents mounted on a single robot to achieve tasks quickly. Responding to environmental changes using normal reinforcement learning can be challenging. However, HMARL does not consider the use of multiple agents to address environmental changes. In this study, we filtered the agents in HMARL using information entropy to realize a robot capable of maintaining high task achievement rates in response to environmental changes.

Authors: Chen Fangxuan , Wang Shihao , Dejam Morteza , Nasrabadi Hadi
Published: March 2024

As a clean energy carrier, hydrogen (H2) is considered an indispensable part of the energy transition roadmap. To meet increasing energy demand, extremely large storage capacities are required. Previous studies have focused on underground H2 storage in conventional depleted gas reservoirs, salt caverns, and saline aquifers. The increasing number of depleted shale gas reservoirs may be good candidates for H2 storage. In this work, we analyze the potential of H2 storage in depleted gas reservoirs using Monte Carlo (MC) simulations. The competitive adsorption of a methane-hydrogen (C1-H2) system under nanoscale conditions is investigated, including the effects of pore size, temperature, pressure, boundary material, and fluid composition. Our results show that C1 is preferentially adsorbed in a C1-H2 system. C1 forms the adsorption layer near the boundary surface, while H2 molecules are freely distributed in the pore. The fluid distribution indicates that H2 can be easily produced during H2 recovery processes, which contributes to H2 storage in depleted shale gas reservoirs. In addition, the effect of water on C1-H2 competitive adsorption is analyzed. The strong interactions between water and boundary atoms force C1 molecules away from the adsorbed region. This work provides a foundation for hydrogen storage in depleted shale gas reservoirs at a molecular level.

Importance
Vitiligo is a chronic skin disorder causing depigmentation. There is lack of evidence-based medical evidence regarding ruxolitinib efficacy and safety for Vitiligo.
Objective
To assess the efficacy and safety of ruxolitinib cream in treatment vitiligo.
Methods
The databases of PubMed, Embase, and Cochrane Library were searched. The literature screening was independently conducted by two reviewers.
Data extraction and synthesis
For continuous variables, weighted mean difference (WMD) along with a 95% confidence interval (CI) was performed. For dichotomous outcomes, we calculated the odds ratios (ORs) or risk ratios (RRs), and their corresponding 95% CIs. The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).
Main outcomes and measures
Symptoms, quality of life, and safety were evaluated using various measures, including the Facial Vitiligo Area Scoring Index (F-VASI), Total Vitiligo Area Scoring Index (T-VASI), Facial Body Surface Area (F-BAS), Total Body Surface Area (T-BAS) and Treatment-emergent Adverse Events (TEAEs).
Results
Three trials, involving a total of 830 participants from nine countries were included (female: 388, 46.7%, male: 442, 53.3%). The meta-analysis demonstrated a significant increase in the likelihood of participants achieving F-VASI75 (OR, 4.34 [95% CI, 2.67-7.06]; high), F-VASI50 (OR, 4.71 [95% CI, 3.24-6.84]; high), T-VASI75 (OR, 2.78 [95% CI, 1.10-7.00]; moderate), and T-VASI50 (OR, 4.47 [95% CI, 2.52-7.92]; high) when compared ruxolitinib to vehicle. Ruxolitinib were associated with more lowered percentage change of F-VASI scores (MD, –32.79 [95% CI, −36.37 to −29.21]; moderate), and T-VASI scores (MD, –20.22 [95% CI, −23.11 to −17.33]; moderate) from baseline compared to vehicle. There may not be a significant difference in the occurrence of TEAEs between ruxolitinib and vehicle (RR, 1.46 [95% CI, 0.85-2.49]; high).
Conclusions
The findings suggest that ruxolitinib cream holds promise as a treatment option for vitiligo. Further long-term studies are needed to assess its sustained efficacy and safety profile.

The accumulation of metal(loid)s in soils, often linked to human activities, is a source of toxicity for living organisms. Erosion and leaching from contaminated sites can spread pollution to adjacent ecosystems. Phytostabilization is a method that consists of selecting plant species accumulating little or no metal(loid)s in aerial parts to establish a vegetation cover and thus to stabilize the soil. Seeds of white lupin, cultivated vetch, and buckwheat were sown in greenhouse on soils from former French mines (Pontgibaud and Vaulry) contaminated with several metal(loid)s including high concentrations of arsenic and lead. After 4 weeks of exposure, the growth of white lupin was less affected than that of the 2 other species probably because the concentration of metal(loid)s measured in the roots and aerial parts of lupins was lower. In addition, the level of antioxidant molecules and metal(loid) scavenging compounds was higher in white lupin suggesting that this species could be a good candidate for metal(loid) phytostabilization. However, the level of oxidation was higher than in control plants, suggesting that amendments could be tested to improve the tolerance of this species to metal(loid)s.
Integrative Analysis of Lipid Metabolism-Associated Genes Unveils ALDH2 as a Prognostic Marker in Breast Cancer

Published: March 2024

The oncogenesis and development of breast cancer is closely related to abnormal lipid metabolism. We focused on the identification of pivotal lipid metabolism-associated genes (LMAGs) and constructed a prognostic signature (ALDH2, CYP21A2, and IL24) by LASSO and Cox regression. Survival and time-dependent ROC analysis demonstrated the predictive accuracy of our signature in both training and validation cohort. Additionally, patients in high-risk group showed an immunosuppressive phenotype with lower abundance of immune cells and down-regulation of recognized immune checkpoints. Subsequent cellular experiments indicated that the downregulaiton of ALDH2 was correlated with the aggressive behavior of breast cancer cells. These findings offer crucial insights into understanding the interplay between lipid metabolism and breast cancer progression, potentially paving the way for innovative strategies to impede breast cancer metastasis.
A case of sarocladium strictum caused severe meningoencephalitis and cerebral vasculitides: a case report and literature review
Authors: Shi Wenzhi , Liu Yue , Lu Juanjuan , Li Rui , Huang Shan
Published: March 2024

Background: Sarocladium strictum(S.Strictum) under the order Hypocreales, has usually been considered an opportunistic phytopathogen. Early recognition of S.Strictum is difficult due to its nonspecific clinical manifestations such as headaches and fever. Culture and gene probe techniques for S.Strictum are not available for conventional clinical applications, which also makes the diagnosis difficult. In limited and rare reported cases of central nervous system infections, the case of meningitis combined with lethal vasculitis, with etiologic diagnosis aided by the use of metagenomic next-generation sequencing (mNGS), is still uncommon. So, it is necessary to report and review such potentially fatal case.
Case presentation: This report describes a 42-year-old female with sarocladium strictum caused severe meningoencephalitis and cerebral vasculitides. She presented with symptoms of fever and headache, accompanied by hemiplegia. Her condition deteriorated rapidly to coma under the treatment of empirical antibacterial agents. The mNGS of the cerebrospinal fluid (CSF) identified sequence reads corresponding to S.strictum infection. Furthermore, blood culture provided validation. Combined use of targeted antifungal agents of fluconazole and amphotericin B was carried out, and the patient’s condition improved. Unfortunately, her condition deteriorated a month later.
Conclusion: mNGS is a promising detection method for S.Strictuminfection and is recommended. When clinicians come across a patient with meningitis triggered by S.strictum infection, lethal vasculitis should be taken into consideration. The combination therapy of antifungal and anti-vasculitis may be a promising treatment method.
More than stridulation: signal interaction and constraint in the complex vibroacoustic courtship of a cricket

Published: March 2024

Crickets (Gryllidae) produce sounds by tegminal stridulation, extensively studied for its role in female attraction and choice. However, their close-range courtship song, along with additional chemical, visual, and thermal signals, fails to clarify the observed female preferences. Beyond stridulation, crickets exhibit a range of vibrational courtship behaviours that remain largely unexplored. In this study, using Acheta domesticus as a model, we present the first comprehensive analysis of the entire set of vibroacoustic courtship signals in crickets, including their interaction. Employing audio recording, laser vibrometry, and videorecording, we unveil a complex signal involving simultaneous wing stridulation, body tremulation, and leg drumming against the substrate. These signal components exhibit a pattern of regular exchange within a specific time window relative to each other. We show the tightest coupling between the two types of stridulation pulses, and between tremulation and drumming signals, supported by the linear corelation of their rates. The coupling between drumming and stridulation signals is less consistent, with the non-linear corelation between their temporal and association parameters revealing a constraint on drumming performance. Yet, drumming is performed with high accuracy relative to stridulation, unrelated to its rate. Spectral-intensity analysis indicates the closest perceptual and thus functional connection between stridulation and drumming components of the complex signal, while proposing another function for tremulation unrelated to female choice. Our data demonstrate that the information conveyed by the complex courtship display in A. domesticus is not simply proportional to that in the song, potentially providing a much more reliable basis for female choice.

Colon cancer is a prevalent malignancy, while recent studies revealed the dys-regulation of Hippo signaling as the important driver for colon cancer progression. Several studies have indicated that post-translational modifications on YAP play crucial roles in both Hippo signaling activity and cancer progression. This raises a puzzling question about why YAP/TAZ, an auto-inhibitory pathway, is frequently over-activated in colon cancer, despite the suppressive cascade of Hippo signaling remaining operational. The protein stability of YAP is subject to a tiny balance between ubiquitination and deubiquitination processes. Through correlation analysis of DUBs (deubiquitinases) expression and Hippo target gene signature in colon cancer samples, we found JOSD1 as a critical deubiquitinase for Hippo signaling and colon cancer progression. JOSD1 could facilitate colon cancer progression and in colon cancer, inhibition of JOSD1 via shRNA has been demonstrated to impede tumorigenesis. Furthermore, molecular mechanism studies have elucidated that JOSD1 enhances the formation of the Hippo/YAP transcriptome by impeding K48-linked polyubiquitination on YAP. ChIP assays have shown that YAP binds to JOSD1's promoter region, promoting its gene transcription. These results suggest that JOSD1 is involved in both activating and being targeted by the Hippo signaling pathway in colon cancer. Consequently, a positive regulatory loop between JOSD1 and Hippo signaling has been identified, underscoring their interdependence during colon cancer progression. Thus, targeting JOSD1 may represent a promising therapeutic approach for managing colon cancer.
A case report of rare Zinner syndrome: An ejaculatory duct cyst was present Instead of an ipsilateral seminal vesicle cyst

Published: March 2024

Background
Zinner syndrome (ZS) is a malformed triad of congenital mesonephric (Wolffian) duct dysplasia that was first described by Zinner in 1914. ZS consists of unilateral renal hypoplasia or dysplasia, ipsilateral seminal vesicle cysts, and obstruction of the ejaculatory duct. The present case is a rare type of syndrome in which an ejaculatory duct cyst was observed rather than an ipsilateral seminal vesicle cyst. The ejaculatory duct cyst involved the vas deference bilaterally, resulting in bilateral seminal vesicle gland atrophy or erosion, without apparent seminal fluid, which caused azoospermia and infertility.
Case presentation:
The patient had only a feeling of incomplete defecation, accompanied with a little anal distension before surgery. No sperm were found on two semen examinations, and magnetic resonance imaging/magnetic resonance urography (MRI/MRU) suggested the absence of a left renal component and the possibility of a seminal vesicle cyst. We considered that the azoospermia was caused by compression of the contralateral ejaculatory duct by a seminal vesicle cyst on the affected side, so we decided on laparoscopic resection. No seminal vesicle cyst was found during the operation, but an ejaculatory duct cyst was detected in which the bilateral vasa deferentia merged with no other outlet. We resected the cyst. After surgery, the patient's clinical symptoms disappeared, but the infertility problem could not be solved.
Conclusion
Although we had a preliminary confirmation of the ZS diagnosis with azoospermia before surgery, it exhibited a variation that has not been reported in the literature, and such a variation could not be resolved by surgical resection alone. Preoperative deferento-vesiculography(DVG) is necessary to confirm the diagnosis. Assisted reproductive technology could be utilized for the azoospermia caused by the ZS.
