Published: November 2024

Quantum state teleportation represents a pillar of quantum information and a milestone on the roadmap towards quantum networks with a large number of nodes. Successful photonic demonstrations of this protocol have been carried out employing different qubit encodings. However, demonstrations in the Fock basis encoding are challenging, due to the impossibility of generating a coherent superposition of vacuum-one photon states on a single mode with linear optics. Indeed, previous realizations only allowed the teleportation of dual-rail entangled states, by exploiting ancillary electromagnetic modes. Here, instead, we enable the quantum teleportation of pure vacuum-one-photon qubits encoded in a single spatial mode, by exploiting coherent control of a resonantly excited semiconductor quantum dot in a micro-cavity. Within our setup, we can both teleport genuine single-rail vacuum-one-photon qubits and perform entanglement swapping. Our results may disclose new quantum information processing potentialities for this encoding, whose manipulation is achievable via quantum dot single-photon sources.
Meiotic DNA break resection and recombination rely on chromatin remodeler Fun30

Published: November 2024

DNA double-strand breaks (DSBs) are nucleolytically processed to generate single-stranded DNA for homologous recombination. In Saccharomyces cerevisiae meiosis, this resection involves nicking by the Mre11–Rad50–Xrs2 complex (MRX), then exonucleolytic digestion by Exo1. Chromatin remodeling at meiotic DSBs is thought necessary for resection, but the remodeling enzyme was unknown. Here we show that the SWI/SNF-like ATPase Fun30 plays a major, nonredundant role in meiotic resection. A fun30 mutation shortened resection tracts almost as severely as an exo1-nd (nuclease-dead) mutation, and resection was further shortened in a fun30 exo1-nd double mutant. Fun30 associates with chromatin in response to DSBs, and the constitutive positioning of nucleosomes governs resection endpoint locations in the absence of Fun30. We infer that Fun30 promotes both the MRX- and Exo1-dependent steps in resection, possibly by removing nucleosomes from broken chromatids. Moreover, the extremely short resection in fun30 exo1-nd double mutants is accompanied by compromised interhomolog recombination bias, leading to defects in recombination and chromosome segregation. Thus, this study also provides insight about the minimal resection lengths needed for robust recombination.

Authors: Li Shuo , Elgendi Mohamed , Menon Carlo
Published: November 2024

Remote photoplethysmography (rPPG) has gained prominence as a non-contact and real-time technology for heart rate monitoring. A critical factor in rPPG’s accuracy is the selection of regions of interest (ROI), as it can significantly influence prediction outcomes. Most studies typically use the forehead and cheeks as ROIs, but little research has explored other facial regions or how stable these ROIs are during physical movement and cognitive tasks. In this study, we analyzed 28 facial regions based on anatomical definitions using two mixed datasets derived from three public databases: LGI-PPGI, UBFC-rPPG, and UBFC-Phys. We applied rPPG algorithms such as orthogonal matrix image transformation (OMIT), plane-orthogonal-to-skin (POS), chrominance-based (CHROM), and local group invariance (LGI). Our findings show that the glabella, medial forehead, lateral forehead, malars, and upper nasal dorsum consistently perform well, with the glabella achieving the highest overall evaluation score. These results offer valuable insights for advancing remote heart rate monitoring technologies.
Current Prospects of Indian Seaweed and Its Value-added Products
Authors: Jaikumar Muthuswamy , Ramadoss Dineshram , Surendran Sreelakshmi , Behera Anil Kumar
Published: November 2024

Seaweeds are macroscopic algae that live in shallow marine waters and rocky shorelines. These are considered the “wonder plants of the sea,” encompassing a novel and sustainable supply of chemicals, food, energy, and pharmaceuticals with many applications in business, farming, biomedicine, and personal hygiene. In addition to nourishing marine life, seaweed plays a vital role in absorbing nutrients from saltwater and transferring them into the food chain. Historically, India has not made extensive use of seaweeds. However, seaweeds are currently highly valued in the Indian market and are widely used as biostimulants. Less than 1% of the nation’s total agricultural area is treated with these substances to enhance plant productivity. The goal of this review is to determine how best to use seaweed in the manufacture of several value-added seaweed products and how to get good consumer recognition for these products. Seaweeds are mostly used as a component of agarose, carrageenan, and agar, which are used in pharmaceuticals, cosmetics, paints, cardboards, paper, and processed foods, among other things. India has 46 different industries based on seaweed, of which 25 manufacture alginate and 21 produce agars. However, they are not performing at their full capacity due to a shortage of raw resources. The cultivation of additional seaweed species that are beneficial for food and other value-added businesses in the country should be promoted by Indian nodal bodies.

Characteristics of phage-plasmids and their impact on microbial communities
Authors: Sayid Ruweyda , van den Hurk Anne W.M. , Rothschild-Rodriguez Daniela , Herrema Hilde , de Jonge Patrick A. , Nobrega Franklin L.
Published: November 2024

Bacteria host various foreign genetic elements, most notably plasmids and bacteriophages (or phages). Historically, these two classes were seen as separate, but recent research has shown considerable interplay between them. Phage-plasmids (P-Ps) exhibit characteristics of both phages and plasmids, allowing them to exist extrachromosomally within bacterial hosts as plasmids, but also to infect and lyse bacteria as phages. This dual functionality enables P-Ps to utilize the modes of transmission of both phage and plasmids, facilitating the rapid dissemination of genetic material, including antibiotic resistance and virulence genes, throughout bacterial populations. Additionally, P-Ps have been found to encode toxin-antitoxin and CRISPR-Cas adaptive immune systems, which enhance bacterial survival under stress and provide immunity against other foreign genetic elements. Despite a growing body of literature on P-Ps, large gaps remain in our understanding of their ecological roles and environmental prevalence. This review aims to synthesise existing knowledge and identify research gaps on the impacts of P-Ps on microbial communities.
Sulphotransferase-mediated toxification of chemicals in mouse models: effect of knockout or humanisation of SULT genes
Authors: Glatt Hansruedi , Meinl Walter
Published: November 2024

Cytosolic sulphotransferase (SULT) enzymes catalyse reactions involved in xenobiotic elimination and hormone regulation. However, SULTs can also generate electrophilic reactive intermediates from certain substrates, including the activation of carcinogens. Here, we review toxicological studies of mouse strains with SULT status altered by genetic modification. Knockout mouse strains have been constructed for the enzymes Sult1a1, 1d1, 1e1, 2b1 and 4a1. In addition, transgenic strains are available for human SULT1A1/2. Among SULT knockout mouse strains, reduced fertility (Sult1e1) and early postnatal death (Sult4a1) were observed. In contrast, Sult1a1 or Sult1d1 knockouts and SULT1A1/2 transgenics were healthy and showed no obvious deficiencies. These strains were used in toxicological studies with 13 chemicals. Manipulation of the SULT system altered dramatically the adverse effects of many compounds; thus, very large differences in levels of DNA adducts formed in the liver or other tissues were seen with some chemicals – up to 99.2% decreases in knockouts and 83-fold increases in SULT1A1/2 transgenics. In many cases, these changes were restricted to the tissues in which the corresponding enzymes are expressed, arguing for local activation. However, with some compounds, the kidney was an important target tissue, due to the active transfer to that organ, via the circulation, of reactive sulphuric acid esters.

Authors: Liu Cong , Xing Bo , Li Zhuoran , Li Junhua , Xiao Minfeng
Published: November 2024

Bacteriophages, viruses that infect bacteria, play a crucial role in manipulating the gut microbiome, with implications for human health and disease. Despite the vast amount of data available on the human gut virome, the number of cultured phages that infect human gut bacteria—particularly obligate anaerobes—remains strikingly limited. Here, we summarize the resources and basic characteristics of phages that infect the human gut obligate anaerobe. We review various methods for isolating these phages and suggest a strategy for their isolation. Additionally, we outline their impact on the field of viral biology, their interactions with bacteria and humans, and their potential for disease intervention. Finally, we discuss the value and prospects of research on these phages, providing a comprehensive ‘Roadmap’ that sheds light on the ‘dark matter’ of phages that infect human gut obligate anaerobes.
KitWaSor: Pioneering pre‐trained model for kitchen waste sorting with an innovative million‐level benchmark dataset
Authors: Fang Leyuan , Ding Shuaiyu , Feng Hao , Yu Junwu , Tang Lin , Ghamisi Pedram
Published: November 2024

Intelligent sorting is an important prerequisite for the full quantitative consumption and harmless disposal of kitchen waste. The existing object detection method based on an ImageNet pre‐trained model is an effective way of sorting. Owing to significant domain gaps between natural images and kitchen waste images, it is difficult to reflect the characteristics of diverse scales and dense distribution in kitchen waste based on an ImageNet pre‐trained model, leading to poor generalisation. In this article, the authors propose the first pre‐trained model for kitchen waste sorting called KitWaSor, which combines both contrastive learning (CL) and masked image modelling (MIM) through self‐supervised learning (SSL). First, to address the issue of diverse scales, the authors propose a mixed masking strategy by introducing an incomplete masking branch based on the original random masking branch. It prevents the complete loss of small‐scale objects while avoiding excessive leakage of large‐scale object pixels. Second, to address the issue of dense distribution, the authors introduce semantic consistency constraints on the basis of the mixed masking strategy. That is, object semantic reasoning is performed through semantic consistency constraints to compensate for the lack of contextual information. To train KitWaSor, the authors construct the first million‐level kitchen waste dataset across seasonal and regional distributions, named KWD‐Million. Extensive experiments show that KitWaSor achieves state‐of‐the‐art (SOTA) performance on the two most relevant downstream tasks for kitchen waste sorting (i.e. image classification and object detection), demonstrating the effectiveness of the proposed KitWaSor.
Lattice‐Based CP‐ABE for Optimal Broadcast Encryption With Polynomial‐Depth Circuits
Authors: Ma Shaohua , Zhao Zongqu , Wang Naifeng , Zha Chunming
Published: November 2024

Most current broadcast encryption with optimal parameters is limited to Nick’s class 1 (NC1) circuits and does not support polynomial‐depth circuits (P‐depth circuits), making it difficult to provide flexible access control in broadcast channels among vast user groups. To address this problem, we propose a ciphertext‐policy attribute–based encryption (CP‐ABE) that supports P‐depth circuits on lattices, achieving fully collusion resistance with randomization via the matrix tensors, thereby, making it impossible for unauthorized users to get any details about the plaintext even though they join forces and reducing the security to the evasive learning with errors (evasive LWE). By using matrix tensor–based randomization and evasive LWE, we achieve a new optimal broadcast encryption scheme based on lattice specifically designed to support P‐depth circuits. Since the matrices we choose as tensors have a low‐norm block diagonal structure, the use of evasive LWE is sufficient to ensure security for our scheme. Compared with similar studies, it not only avoids being involved with low‐norm matrices that restrict the system to NC1 circuits, but also eliminates the need for an additional assumption of the unproven tensor LWE. In addition, the use of matrix tensors further expands the dimensionality, which in turn enables the encryption of bit strings rather than a single bit, significantly reducing ciphertext expansion. Meanwhile, the CP‐ABE that we use to achieve the broadcast encryption scheme has a more compact ciphertext with a parameter size of O(m2 · d).

Published: November 2024

Indonesia’s tsunami-prone areas are primarily located in the Pacific Ring of Fire, where the collision of three active tectonic plates (Eurasia, Indo-Australia, Pacific) results in significant seismic activity. This geological condition places several coastal regions at high risk, particularly for earthquakes and tsunamis. One such area is the Ciletuh–Palabuhanratu UNESCO Global Geopark (CPUGG) in Sukabumi Regency. This study aims to develop a tsunami disaster risk reduction strategy for the region, using a quantitative descriptive method. The study finds that the tsunami disaster risk level in CPUGG is 0.64, indicating a moderate risk that borders on high. The proposed risk reduction strategies are categorized into three levels, focusing on government, community, business, and tourist preparedness. The findings highlight that most hazard and vulnerability indicators remain high, while tourist capacity and preparedness are at a moderate level. The strategies suggested by the study could serve as valuable input for mitigating tsunami risks in CPUGG.

Authors: Ihsan Haikal Muhammad , Isya Herdien Raka Moch
Published: November 2024

The Sentinel-1 product can be built into a Synthetic Aperture Radar (SAR) capable of providing terrain data that can be built into landslide mapping parameters. Landslide becomes a disaster if there are affected areas, one of which is an agricultural area, so mapping the landslide hazard in agricultural areas is very important to study. The purpose of this study is to utilize Sentinel-1 products in mapping landslide hazards in agricultural areas in Sumedang Regency. The parameters used are the slope of the SAR data, geological conditions, soil conditions and meteorological conditions. The method used is the overlay intersect technique in which each weight and parameter score refers to the INARISK guidelines of the National Disaster Management Agency. Based on the analysis of the landslide area in Sumedang Regency, it tends to spread in the Southern Region. This area is a complex of hills with steep slopes, old volcanic parent rock which is quite brittle, high rainfall, clay soil texture, and the largest area of lineaments. The biggest proportion of landslide hazard lies in dry land agriculture with a percentage of 75.75%. Sentinel-1 can be an alternative to landslide mapping by building a SAR product into several slope parameters.

Published: November 2024

Indonesia has a lot of natural resource wealth, but on the other hand, Indonesia has various threats or risks of natural disasters as a logical consequence of Indonesia’s geographical conditions. One of the disasters that often occurs in Indonesia is landslides. The West Java Province region, in this case Tasikmalaya Regency, which contains the Naga Traditional Village, has the potential for landslides because it has a hilly morphology. So, this research not only aims to analyze the potential for landslides in Kampung Naga, but also aims to analyze how to deal with landslides through the local wisdom of the Kampung Naga community. The method used is a scoring and weighting method using a Geographic Information System (GIS), which involves several thematic data, namely data on land use, rainfall, soil type, geology and slope in the research area, which is adjusted to the estimation model from Puslittanak. Then use the Qualitative Descriptive method to analyze the traditional wisdom or local wisdom of the community in dealing with landslide disasters. The research results show that based on the analysis, landslide potential falls into three categories, namely very low, low and medium. Then the traditional wisdom or local wisdom of the community in dealing with landslides is by making terraces which is called entep stone or umpak stone , with stones obtained from the Ciwulan River next to the village. Apart from that, the community also continues to protect the land cover on the hill by making it a prohibited forest (Leuweung Larangan) and a forest entrustment (Leuweung Titipan) , so that its use can be well controlled, and maintain the strength of the soil.

Authors: Logayah Dina Siti , Ruhimat Mamat , Maryani Enok , Arrasyid Riko
Published: November 2024

The aim of this research is because Indonesia is geographically and geologically the most disaster-prone country in the world. Based on this phenomenon, education can anticipate the high number of disaster victims. Learning at school is one of the bridges to student preparedness through the disaster literacy model. The research method used is Research and Design (R&D). Data collection uses documentation, questionnaires, tests and interviews. The results of the research show that most students have sufficient knowledge regarding disaster literacy, curiosity about disaster material is very high, attitudes during a disaster show high awareness, and awareness of disaster literacy is good. The weakness is that students only understand disasters from the media and their skills in dealing with disasters are still low. The implication of this research is that disaster literacy provides an opportunity in schools to form a character that cares about disasters.

In social science subjects for junior high school students, spatial themes cover a variety of topics, namely spatial interrelation and interdependence, spatial interaction, as well as interspace excellence and limitations. Spatial concept understanding will help students to attain Basic Competences (Kompetensi Dasar/KD), which in general is to understand, analyze, and explain how location and places affect patterns of human activities. The limitation of the lecture method on delivering spatial concepts became the background of this research. In order to improve student activities through scaffolded teaching, the activity of finding information through location tracking is implemented. To analyze the whole process, this research uses a qualitative experimental method. The study shows the increases in student participation during class session, formative test scores, and amount of time reduced in finding answers. The result of this research shows that Location Tracking Activity has increased students’ activity during the learning process, as well as motivation of learning. The experiment process resulted in the attainment of basic competencies in students’ learning process, as well as 40% increase in students participation during the class; 35% increase in cooperating with their classmates during discussion; and 40% increase in interacting with the teacher.

The change in the implementation of face-to-face learning to online during the Covid-19 pandemic requires teachers to adapt the learning system. In the Geographic Information Systems (GIS) subject, the delivery of GIS material to students often remains theoretical, lacking practical application. To address this, teacher selfdevelopment efforts are needed to support the competency improvement during the online class by participating in training. This study aims to analyze the effectiveness of online GIS training for geography teachers. The method used is descriptive analysis with a qualitative approach and data collection using literature review and interviews. The results found that teacher participation in training acts as a form of professional self-development, enhancing theacher’s knowledge and professional competence. During the pandemic, various trainings can be easier to follow, in addition to maintaining distance, online training can also bridge the barriers of distance and location of implementation. Online GIS training in particular can still improve teacher competence, but there are obstacles for some teachers who are lacking in managing information technology tools. The role of the presenters as well as the detailed training modules will greatly help the training objectives to be achieved.
Sustainability life of lobster (sp. Locusta) in the coral reef NRF Sancang Area
Authors: Sugandi Dede
Published: November 2024

Lobsters are shallow water organisms and are often caught by fishermen traditionally. The aim of the research is to analyze natural lobster catching, the sustainability of lobsters (sp.locusta) and baby lobsters (sp.infantem locustam) and forms of coral reef conservation in the NRF Sancang area. The method used is descriptive with qualitative interviews. Mapping of the NRF of Sancang coral reef area by analyzing Landsat 8 images in 2023, ground checks and interviews. Tracing is done at night using boats, nets and petromak or LED lights with the aim that the lobsters (sp.locusta) will get closer to the center of the light. Lobster (sp.locusta) has a high selling value, so it attracts fishermen to catch both baby lobsters (sp.infantem locustam) and their mothers. Adult lobsters are sold for consumption, while baby lobsters (sp.infantem locustam) are sold outside the region and even abroad to be kept, which threatens the sustainability of lobsters (sp.locusta) in the HCA Sancang coral reef area. Because of this, conservation is needed by implementing strict regulations.

The Pacitan Regency, located on the southern coast of Java adjacent to the Indian Ocean, is susceptible to tsunami disasters due to its geographical location. Therefore, mitigation efforts are essential, including the development of tsunami modeling and evacuation strategies. While previous studies have combined these aspects, simulations involving simultaneous evacuation of both coastal residents and tourists remain scarce. This research aims to simulate the evacuation of coastal residents and tourists during various tsunami scenarios resulting from seismic activities, with the goal of formulating an optimal evacuation model. The study employs a tsunami propagation model utilizing numerical methods based on Shallow Water Equations and HLOSS calculations in the Delft3D-Flow software to assess tsunami hazards. The results from the modeling indicated that the highest tsunami run-up height was recorded at maximum 8.78 meters. Various tsunami inundation models are generated using the software and combined as composites to produce comprehensive tsunami hazard maps. This integrated approach provides valuable insights into optimizing evacuation procedures for both local inhabitants and tourists, thereby enhancing disaster preparedness and response strategies in The Pacitan Coastal Areas of Indonesia.

Adaptation of climate change and environmental pollution in Cirebon’s coastal community
Authors: Mulyadi Asep
Published: November 2024

Climate change and environmental pollution are interrelated global phenomena. Communities whose lives depend on natural resources have felt many negative impacts from both. Coastal communities, which mostly depend on the capture fisheries, are a vulnerable group to these threats. The study aims to reveal the adaptation of coastal communities in Cirebon, Indonesia to facing climate change and environmental pollution. This research is located in Gebang Cirebon Regency. Data were obtained from field observations and unstructured interviews which were synthesized to know their adaptive behaviour. We found the adaptation of coastal communities through non-environmentally fishing gears, expansion of fishing areas, burden of debt and capital, not optimal fisherman regeneration, and changes in occupation. Despite changes in mindset, attitude, and behaviour, these adaptations have the potential to threaten a regional and national economy because the fisheries sector is the main contributor of gross domestic product. Declining yield catches and the desire to obtain high economic benefits quickly without paying attention to sustainability, are also the main driving factors for the emergence of maladaptive behaviour in coastal communities. Without serious attention, climate change and environmental pollution will trigger socio-economic impacts that are worse than COVID-19 pandemic.
