Published: February 2025

Abstract
The tropical coniferous genus Dacrydium is widespread in Kalimantan, Indonesia. Four species can still be found in Borneo. Locally known as Alau, this genus thrives in a range of habitats from heath to deep-peat forests especially in Central Kalimantan. This genus is currently threatened by logging, fires and forest conversion forto other uses. The objectives of this study wereas to unravel the genetic diversity of Dacrydium in the study area which is a large unified diverse landscape. Our research was conducted in heath forests located within PT Taiyoung Engreen logging company area in the Gunung Mas District, and PT Dasa Intiga in the Kapuas District and in deep-peat swamp forest located in Sebangau National Park in the Palangkaraya District. The four species that are suspected to exist in Kalimantan, namely Dacrydium beccarii Parl., Dacrydium pectinatum de Laub., Dacrydium elatum (Roxb.)Wall. ex Hook. and Dacrydium xanthandrum Pilg. were met in various abundances. Genetic data were tested by isoenzyme analysis with 20 samples of each species of D. beccarii and D. pectinatum from each site. The results showed that D. beccarii and D. pectinatum have a large number of missing alleles, rare alleles, and individual alleles, which are found in different species in the three research sites, all show their own genetic peculiarities. That makes it necessary to develop a strategy to protect the genus Alau quite locally, especially D. pectinatum is of high concern as it is quite threatened. Genetic diversity values of D. beccarii and D. pectinatum have genetic diversity in population 0.478 and 0,447, interpopulation diversity 0.208 and 0,253, roportion of genetic diversity between populations to total genetic diversity 0.289 and 0,350 with fixation index values (-0.021) and 0,187 (≈0) it has a tendency to random mating. Itis necessary to implement a strategy for saving Dacrydium. This can be implemented from our research site. Actions will include the translocating of individual seedlings between research sites where each has a private allele with different advantages to be planted in all original habitat to increase genetic variation, and establish demonstration plots to safeguard genetic variation and diversity, and additionally carry out genetic enrichment planting, especially for D pectinatum.

Abstract
This study explores the cultural identity of the Roko Molas Poco ceremony among the Manggarai people of East Nusa Tenggara, Indonesia. The ceremony, centered around harvesting a special tree for the main pillar (siri bongkok) of their traditional drum house (mbaru gendang), symbolizes the community’s deep connection to the forest as a life-giver and protector. The research examines how this ritual reinforces cultural values, promotes environmental conservation, and strengthens the psychological bond between the Manggarai people and their natural surroundings. An ethnographic approach was employed, focusing on participant observation of the Roko Molas Poco ceremony. By analyzing the symbolism and practices involved in Roko Molas Poco, the study highlights the interplay between cultural identity, traditional wisdom, and forest preservation in Manggarai society.

Abstract
Borneo Island, particularly East Borneo, is known for its rich biodiversity, including endemic species such as the Proboscis Monkey, Rhinoceros Hornbill, and Engkabang tree. However, the extensive urbanization driven by the new Nusantara Capital City (IKN) development potentially poses future threats to the existing rich biodiversity. Although a biodiversity management plan has been conducted, specific studies involving urban design are crucial to ensure that development effectively addresses biodiversity concerns. Accordingly, this research aims to formulate strategies for harmonizing biodiversity into urban life using the biodiversity-sensitive urban design (BSUD) approach in the context of IKN. The methodology uses a biodiversity analysis that begins by identifying target species and analyzing their ecosystem services, characteristics, and habitat requirements. Furthermore, spatial mapping analysis is used to delineate habitat areas vulnerable to the urban development of IKN precincts. Subsequently, the findings inform the formulation of ecology-oriented urban design solutions for IKN, drawing upon established theoretical frameworks and exemplar practices. The result of this research is an urban design strategy for conserving the rich biodiversity and ecology suitable for integration into the urban fabric of IKN through using BSUD methodologies. Ultimately, this study will provide valuable insights to urban actors and IKN stakeholders by contributing academic input to Nusantara’s biodiversity management master plan and act as an effort to mitigate ecological damage due to the development of new cities.

Published: February 2025

Abstract
The concept of nature-based solutions (NBS) emerges as a multidimensional approach to achieve sustainable development while enhancing resilience to environmental hazards, in solving the challenges posed by climate change and rapid urbanization. This article examines the integration of NBS in the development of the new capital city of Indonesia, located in Nusantara, East Kalimantan, focusing on its role in climate resilience and low carbon development. Methodologically, the study explores how NBS can effectively conserve green and blue carbon through a synthesis of literature, case studies, and policy analyses, thereby contributing to carbon sequestration and climate change mitigation efforts. Additionally, the paper examines the potential of NBS in reducing the impacts of hydrometeorological disasters, such as floods and forest fires, which pose significant threats to the region’s ecological integrity and human well-being. By leveraging the natural landscape and ecosystem services, NBS can mitigate urban heat island effects, improve air and water quality, enhance biodiversity, and reduce vulnerability to extreme weather events. Furthermore, the paper emphasizes the importance of stakeholder engagement, including the participation of Masyarakat adat (indigenous communities), in the co-design and implementation of NBS initiatives. Through inclusive governance structures and participatory planning processes, the new capital city can foster social cohesion, equity, and cultural resilience while advancing sustainable urban development goals. Overall, the integration of NBS represents a transformative pathway towards building climate-resilient and livable urban landscapes that serve as models of sustainability for Indonesia and beyond.

Published: February 2025

Abstract
Climate change affects various aspects of human life, including regional landscapes, which are closely related to changes in land use and a decrease in biodiversity. This research aims to understand the impact of climatic conditions on the development of the landscape of the Karangan region, East Kutai Regency, East Kalimantan Province, which experiences environmental pressure from various climatic factors and human activities. This region is also influenced by the activities of oil palm plantations and the crude palm oil (CPO) processing industry. These activities not only change land cover but also have an impact on climate change and increased greenhouse gas emissions from industrial activities, and the conversion of forest land to plantations can accelerate local climate change and impact the adaptation of ecosystems and local communities. A phenomenological approach was applied in this research, with descriptive methods and literature studies to collect climate data, including temperature, humidity, rainfall, and UV index. The research results show that in the past ten years, temperatures in the study area have stabilized at an average of 24-27.5°C, while humidity tends to remain above 80% with alarm in any given year. Rainfall has shown a decline over the last four years, which has an impact on the availability of air for the community, and the UV index in this area also shows high values, ranging between 6-9, which has the potential to affect local vegetation. It is hoped that these findings will become the basis for climate adaptation efforts and improving the quality of the environment in the region.

Published: February 2025

Abstract
Ibu Kota Nusantara (IKN) has a target of realizing the availability of at least 75% of conservation area. This conservation area is also one of the key performance indicators for measuring the success of development in IKN. This target is not easy to achieve because within the IKN area there are still several problems or activities that have an impact on environmental conditions in IKN. Such kinds of problems are closely related to environmental law aspects. This study discusses several challenges that are still problems that could hinder the availability of conservation area in IKN. This study uses normative legal research method, and relies on secondary data. The information or data in this study are taken from several primary and secondary legal materials or documents. Several information obtained through Focus Group Discussion will also be examined. To draw conclusions, qualitative data analysis will be carried out.

Abstract
To address the future application requirements of carbon-based material grids for ion thrusters characterized by high thrust, elevated specific impulse, and extended operational life, research was conducted using the LIPS-100 ion thruster developed by the Lanzhou Institute of Physics. This study focused on small-diameter configurations of carbon-carbon composite material grids. Successful development was achieved for both a 10 cm split carbon-carbon planar grid and an integrated carbon-carbon convex grid component. Performance variations among different configurations were investigated through extensive performance tests across the wide-range from 1 to 25 mN, as well as 200 h lifespan assessments under typical conditions at 20 mN. The results indicate that the two configurations of the carbon-carbon grid can achieve stable operation across the broad range of 1–20 mN, with beam current fluctuations ranging from 368 to 379 mA and accel grid current fluctuations between 1.58 and 1.81 mA. Furthermore, the key performance parameters of these grids were comparable to those of the traditional molybdenum grids. Under conditions of high thrust and power, the carbon-carbon grid demonstrated a significant reduction in the intercepted current at the accel grid. In comparison to the split carbon-carbon planar grid, the weight of the integrated carbon-carbon convex composite grid was reduced by 17.5%, the anode voltage decreased by approximately 2.4%–8.6%, and the cathode keeper voltage was reduced by approximately 3.5%–12.4%. It can be concluded that the integrated carbon-carbon convex grid offers distinct advantages in terms of hot-state structural stability, suppression of grid etching rates, and enhancement of thruster discharge efficiency.

Published: February 2025

Abstract
The digital twin model of full-life rolling bearings is of great significance for the prediction of its working condition. The existing digital twin model outputs simulation data, mainly considering the two degrees of freedom of the outer ring of the bearing; and it does not consider the time series of the bearing vibration signal in the virtual-real interaction process, which affects the model prediction accuracy. In this paper, a six-degree-of-freedom full-life rolling bearing digital twin model is proposed. First, a six-degree-of-freedom dynamics model is established as a means of generating simulation data that is closer to the real working state of the bearing. Then the improved CycleGAN combined with DTW dynamic time regularization is used to reduce the error between the simulation data and the measured data and realize the time series regularization. Finally, the digital twin model established in this paper is evaluated by applying the XJTU-SY bearing dataset.&#xD;
What Violent Protestors Want
Authors: Pasternak Avia 
Published: February 2025

Abstract
This chapter explores the core features of the violent protests that are the subject of the analysis. It presents their specific characteristics and demonstrates how they are different from other forms of violent political resistance. First, it describes the injustices that the violent protests we are concerned with here respond to: serious, entrenched domestic injustices. Second, it reviews the political goals of participants in such protests: to bring about social change, to hold to account those in power, to resist political marginalization, and to communicate or express anger and defiance. The chapter reflects on the importance of these goals, setting the stage for the assessment of violence carried out on their behalf.

Abstrat
Water molecules in the vicinity of polymers influence the behaviors of solvated polymeric materials. However, understanding the behavior of these vicinal water molecules is challenging. Using a multivariate curve resolution (MCR) approach, we present a method for extracting the infrared absorption spectra of vicinal water of poly(N-isopropylacrylamide) (PNIPAAm). Our analysis successfully quantified vicinal water molecules, showing significantly higher hydration numbers in the hydrophilic state, providing insights into the role of vicinal water in the temperature-dependent affinity switching of PNIPAAm towards cells.

Published: February 2025

Abstract

Aims
Emerging antihypertensive drug classes offer new opportunities to manage hypertension, however, their long-term effects on cardiovascular, kidney and metabolic (CKM) outcomes remain to be elucidated. This study aims to explore the effects of phosphodiesterase type 5 inhibitors (PDE5i), soluble guanylate cyclase stimulators (sGCs), endothelin receptor antagonists (ERA), and angiotensinogen inhibitors (AGTi) on a range of CKM outcomes.

Methods and Results
Mendelian randomisation (MR), summary-based MR (SMR), and colocalisation analyses were applied to assess the drug effect on coronary artery disease (CAD), myocardial infarction (MI), ischemic stroke, atrial fibrillation (AF), heart failure (HF), type 2 diabetes (T2D), and chronic kidney disease (CKD). Genetic association and gene expression summary data were obtained from the largest European-ancestry genome-wide association studies (GWAS) and the Genotype-Tissue Expression (GTEx) version 8 for 29 tissues relevant to the outcomes' pathophysiology.
Genetically predicted systolic blood pressure (SBP) reduction was associated with reduced risks of all outcomes. PDE5i was associated with reduced risks of CAD (OR per 10-mmHg decrease in SBP: 0.348[95% CI: 0.199–0.607]) and ischemic stroke (0.588[0.453–0.763]). sGCs showed protective effects against CAD (0.332[0.236–0.469]), MI (0.238[0.168–0.337]), and CKD (0.55[0.398–0.761]). ERA and AGTi showed protective effects against CAD and ischemic stroke. SMR and colocalisation supported the association of gene expression levels of GUCY1A3 and PDE5A with CAD and MI risk.

Conclusion
Our study highlights the potential of PDE5i, sGCs, ERA, and AGTi in reducing cardiovascular and renal risks. These findings underscore the necessity for targeted clinical trials to validate the efficacy and safety of these therapies.
Rapidly-rotating early-Earth dynamos in a full-sphere geometry
Authors: Burmann F , Luo J , Marti P , Jackson A 
Published: February 2025

Summary
While the Earth’s magnetic field has existed for 4Gyr or more, most recent estimates for the age of the inner core nucleation date no further back than 1.5Gyr. As a consequence, the relevant geometry for the Earth’s dynamo has been a full sphere for much of its life, fundamentally different from the present day dynamo operating in a spherical shell. We therefore systematically study magnetic field generation in a rapidly-rotating full sphere where convection is driven by heat sources uniformly-distributed throughout the fluid. We observe a rich diversity of behaviour in our solutions, including dipolar and multipolar dominated fields, together with vacillating and chaotically-reversing magnetic fields. At Prandtl number of unity, we construct regime diagrams as a function of three control parameters, namely the Rayleigh, Ekman and magnetic Prandtl number, which show some similarities with the corresponding diagrams for spherical shell dynamos. This study comprehensively demonstrates the feasibility of early-Earth dynamos that operate based on secular cooling of the core.
Data approximation by neural nets for the MRE inverse problem in the frequency and time domains
Authors: J Davies Penny 
Published: February 2025

Abstract
“Stacked” matrix approximation methods for computing the shear modulus in the magnetic resonance elastography (MRE) inverse problem have been shown to work well in both the frequency and time domain formulations, and are robust to moderate levels of noise. However, when finite differences are used to approximate derivatives of the measured displacement the algorithms can break down at high noise levels. Here we show that if instead a neural network is used to approximate the derivatives of the noisy displacement data, then the overall MRE algorithms become much more robust to noise pollution. Extensive tests indicate that the new methods perform extremely well even in the presence of very high levels of noise, and no additional processing or smoothing of the data is required.

Published: February 2025

Abstract
Stable calcium isotopes fractions have long been related to the calcium metabolism in living organisms. The blood and urine proportions of calcium isotopes 44Ca and 42Ca (δ44/42Ca) have recently again attracted attention as a potential diagnostic tool in metabolic bone diseases, in particular osteoporosis. The hypothesis is, that the lighter isotopes (Ca42) get incorporated into bone more quickly, hence δ44/42Ca ratios in urine and serum are higher for bone formation and lower for resorption phases. Therefore δ44/42Ca in blood and urine may serve as an indicator of bone metabolism, potentially reflecting bone density in general. We have conducted clinical characterization by means of laboratory assessment, bone densitometry, high resolution peripheral quantitative computed tomography and isotope analysis to test for the hypothesis in patients with monogenic bone diseases. We included 40 adult subjects with hereditary bone diseases, such as early-onset osteoporosis (EOOP, n = 7), osteogenesis imperfecta (OI, n = 12), hypophosphatasia (HPP, n = 12) and X-linked hypophosphatemia (XLH, n = 9) and controls (n = 17). Regression analyses revealed significant correlations of δ44/42Ca with Ca/creatinineurine (R2 = 0.6200, p&lt;.0001) and bone densitometric parameters were significantly correlated with δ44/42Ca (bone mineral density: δ44/42Caserum R2 = 0.2685, p≤.001; δ44/42Caurine R2 = 0.3554; p&lt;.0002). XLH differed significantly from the other diseases and controls by means of higher δ44/42Caurine. Our results suggest that δ44/42Ca is strongly coupled to urinary calcium excretion in patients with hereditary bone diseases. Significant correlations with bone mineral density suggest an interaction of δ44/42Ca and bone mass though it lacks discriminative power. Further studies are needed to evaluate the utility of δ44/42Ca in clinical practice.
Neural Network-based model of galaxy power spectrum: Fast full-shape galaxy power spectrum analysis
Authors: Trusov Svyatoslav , Zarrouk Pauline , Cole Shaun 
Published: February 2025

Abstract
We present a Neural Network based emulator for the galaxy redshift-space power spectrum that enables several orders of magnitude acceleration in the galaxy clustering parameter inference, while preserving 3σ accuracy better than 0.5% up to kmax=0.25 hMpc−1 within ΛCDM and around 0.5% w0-waCDM. Our surrogate model only emulates the galaxy bias-invariant terms of 1-loop perturbation theory predictions, these terms are then combined analytically with galaxy bias terms, counter-terms and stochastic terms in order to obtain the non-linear redshift space galaxy power spectrum. This allows us to avoid any galaxy bias prescription in the training of the emulator, which makes it more flexible. Moreover, we include the redshift z ∈ [0, 1.4] in the training which further avoids the need for re-training the emulator. We showcase the performance of the emulator in recovering the cosmological parameters of ΛCDM by analysing the suite of 25 AbacusSummit simulations that mimic the DESI Luminous Red Galaxies at z = 0.5 and z = 0.8, together as the Emission Line Galaxies at z = 0.8. We obtain similar performance in all cases, demonstrating the reliability of the emulator for any galaxy sample at any redshift in 0 &lt; z &lt; 1.4. We will make our emulator public at github repository.
