The full neural circuits of conscious perception remain unknown. Using a visual perception task, we directly recorded a subcortical thalamic awareness potential (TAP). We also developed a unique paradigm to classify perceived versus not perceived stimuli using eye measurements to remove confounding signals related to reporting on conscious experiences. Using fMRI, we discovered three major brain networks driving conscious visual perception independent of report: first, increases in signal detection regions in visual, fusiform cortex, and frontal eye fields; and in arousal/salience networks involving midbrain, thalamus, nucleus accumbens, anterior cingulate, and anterior insula; second, increases in frontoparietal attention and executive control networks and in the cerebellum; finally, decreases in the default mode network. These results were largely maintained after excluding eye movement-based fMRI changes. Our findings provide evidence that the neurophysiology of consciousness is complex even without overt report, involving multiple cortical and subcortical networks overlapping in space and time.

Allogeneic natural killer (NK) cell adoptive transfer is a promising treatment for several cancers but is less effective for the treatment of multiple myeloma. In this study, we report on quadruple gene-engineered induced pluripotent stem cell (iPSC)-derived NK cells designed for mass production from a renewable source and for dual targeting against multiple myeloma through the introduction of an NK cell-optimized chimeric antigen receptor (CAR) specific for B cell maturation antigen (BCMA) and a high affinity, non-cleavable CD16 to augment antibody-dependent cellular cytotoxicity when combined with therapeutic anti-CD38 antibodies. Additionally, these cells express a membrane-bound interleukin-15 fusion molecule to enhance function and persistence along with knock out of CD38 to prevent antibody-mediated fratricide and enhance NK cell metabolic fitness. In various preclinical models, including xenogeneic adoptive transfer models, quadruple gene-engineered NK cells consistently demonstrate durable antitumor activity independent of exogenous cytokine support. Results presented here support clinical translation of this off-the-shelf strategy for effective treatment of multiple myeloma.

Authors: Kim Taek Jung , Ryee Siheon , Han Myung Joon
Published: November 2022

Magnetism in two-dimensional (2D) van der Waals (vdW) materials has lately attracted considerable attention from the point of view of both fundamental science and device applications. Obviously, establishing a detailed and solid understanding of their magnetism is the key first step toward various applications. Although Fe3GeTe2 is a representative ferromagnetic (FM) metal in this family, many aspects of its magnetic and electronic behaviors still remain elusive. Here, we report our new finding that Fe3GeTe2 is a special type of correlated metal known as “Hund metal”. Furthermore, we demonstrate that Hund metallicity in this material is quite unique by exhibiting remarkable site dependence of Hund correlation strength, hereby dubbed “site-differentiated Hund metal”. Within this new picture, many of the previous experiments can be clearly understood, including the ones that were seemingly contradictory to one another.
Multi-omics peripheral and core regions of cancer
Authors: Wang Bingbo , Dong Xianan , Hu Jie , Gao Lin
Published: November 2022

Thousands of genes are perturbed by cancer, and these disturbances can be seen in transcriptome, methylation, somatic mutation, and copy number variation omics studies. Understanding their connectivity patterns as an omnigenic neighbourhood in a molecular interaction network (interactome) is a key step towards advancing knowledge of the molecular mechanisms underlying cancers. Here, we introduce a unified connectivity line (CLine) to pinpoint omics-specific omnigenic patterns across 15 curated cancers. Taking advantage of the universality of CLine, we distinguish the peripheral and core genes for each omics aspect. We propose a network-based framework, multi-omics periphery and core (MOPC), to combine peripheral and core genes from different omics into a button-like structure. On the basis of network proximity, we provide evidence that core genes tend to be specifically perturbed in one omics, but the peripheral genes are diversely perturbed in multiple omics. And the core of one omics is regulated by multiple omics peripheries. Finally, we take the MOPC as an omnigenic neighbourhood, describe its characteristics, and explore its relative contribution to network-based mechanisms of cancer. We were able to present how multi-omics perturbations percolate through the human interactome and contribute to an integrated periphery and core.

Testosterone-related steroid hormones are associated with various types of diseases, including prostate cancer and androgenetic alopecia (AGA). The testosterone or dihydroxy testosterone (DHT) circulates through the blood, binds to the androgen receptor (AR) in the cytoplasm, and finally enters the nucleus to activate downstream target genes. We previously found that immortalized dermal papilla cells (DPCs) lost AR expression, which may be explained by the repeated cell passages of DPCs. To compensate for the AR expression, DPCs that express AR exogenously were established. In this study, we performed an RNA-Seq analysis of the AR-expressing and non-AR-expressing DPCs in the presence or absence of DHT to identify the downstream target genes regulated by AR signalling. Furthermore, we treated DPCs with minoxidil sulphate, which has the potential to treat AGA. This is the first comprehensive analysis to identify the downstream genes involved in testosterone signalling in DPCs. Our manuscript provides high-priority data for the discovery of molecular targets for prostate cancer and AGA.

Published: November 2022

This study analyzed learning curve and the surgical outcome of robotic assisted colorectal surgery with ERAS program. The study results serve as a reference for future robotic colorectal surgeon who applied ERAS in clinical practice. This was a retrospective case–control study to analyze the learning curve of 141 robotic assisted colorectal surgery (RAS) by Da Vinci Xi (Xi) system and compare the surgical outcomes with 147 conventional laparoscopic (LSC) surgery in the same team. Evaluation for maturation was performed by operation time and the CUSUM plot. Patients were recruited from 1st February 2019 to 9th January 2022; follow-up was conducted at 30 days, and the final follow-up was conducted on 9th February 2022. It both took 31 cases for colon and rectal robotic surgeries to reach the maturation phase. Teamwork maturation was achieved after 60 cases. In the maturation stage, RAS required a longer operation time (mean: colon: 249.5 ± 46.5 vs. 190.3 ± 57.3 p < 0.001; rectum 314.9 ± 59.6 vs. 223.6 ± 63.5 p < 0.001). After propensity score matching, robotic surgery with ERAS program resulted in significant shorter length of hospital stay (mean: colon: 5.5 ± 4.5 vs. 10.0 ± 11.9, p < 0.001; rectum: 5.4 ± 3.5 vs. 10.1 ± 7.0, p < 0.001), lower minor complication rate (colon: 6.0% vs 20.0%, p = 0.074 ; rectum: 11.1% vs 33.3%, p = 0.102), and no significant different major complication rate (colon: 2.0% vs 6.0%, p = 0.617; rectum: 7.4% cs 7.4%, p = 1.0) to conventional LSC. Learning curve for robotic assisted colorectal surgery takes 31 cases. Robotic surgery with ERAS program brings significant faster recovery and fewer complication rate compared to laparoscopy in colorectal surgery.

Attractive targeted sugar baits (ATSBs) are a potential vector control tool that exploits the sugar-feeding behaviour of mosquitoes. We evaluated the sugar-feeding behaviour of Anopheles mosquitoes as part of baseline studies for cluster randomised controlled trials of ATSBs. Mosquitoes were collected indoors and outdoors from two villages in western Kenya using prokopack aspirations, malaise tent traps and ultraviolet (UV) light traps. Individual mosquitoes were subjected to the cold anthrone test to assess the presence of sugar. Overall, 15.7% of collected mosquitoes had fed on natural sugar sources. By species and sex, the proportion sugar-fed was 41.3% and 27.7% in male and female Anopheles funestus, 27.2% and 12.8% in male and female An. arabiensis, and 9.7% and 8.3% in male and female An. coustani, respectively. Sugar-feeding was higher in unfed than blood-fed mosquitoes and higher in male than gravid mosquitoes. Anopheles mosquitoes obtained sugar meals from natural sources during all physiological stages, whether they rest indoors or outdoors. These findings offer a potential avenue to exploit for the control of mosquitoes, particularly with the advent of ATSBs, which have been shown to reduce mosquito densities in other regions.
Novel seed generation and quadrature-based square rooting algorithms
Authors: Altamimi Amal , Ben Youssef Belgacem
Published: November 2022

The square root operation is indispensable in a myriad of computational science and engineering applications. Various computational techniques have been devised to approximate its value. In particular, convergence methods employed in this regard are highly affected by the initial approximation of the seed value. Research shows that the provision of an initial approximation with higher accuracy yields fewer additional iterations to calculate the square root. In this article, we propose two novel algorithms. The first one presents a seed generation technique that depends on bit manipulation and whose output is to be used as an initial value in the calculation of square roots. The second one describes a quadrature-based square rooting method that utilizes a rectangle as the plane figure for squaring. We provide error estimation of the former using the vertical parabola equation and employ a suitable lookup table, for the latter, to store needed cosine values. The seed generation approach produces a significant reduction in the number of iterations of up to 84.42% for selected convergence methods. The main advantages of our proposed square rooting algorithm lie in its high accuracy and in its requirement of just a single iteration. Our proposed algorithm also provides for lower computational latency, measured in the number of clock cycles, compared to Newton–Raphson’s and Bakhshali’s square rooting methods.

In order to detect this attack, the present study explores new detection features and establishes a sample set of attack features with different granularities, and accordingly, the Pearson coefficient is used to validate the correlation between the proposed features and the network states. Finally, the Random Forest model is designed to detect the I‐CIFA attack. To evaluate the performance of the approach, extensive experiments are conducted in ndnSIM platform. Test results show that the proposed detection approach outperforms other existing approaches with a detection rate of 98.1%, error rate of 1.9%, and false positive rate of 1.5%.
Multiple‐input multiple‐output sonar adaptive beamforming using transmission diversity smoothing and backward processing
Authors: Fan Kuan , Liu Xionghou , Sun Chao
Published: November 2022

Benefit from the transmission diversity smoothing (TDS) effect upon coherent targets decorrelation, the kind of adaptive beamformers can be directly applied for multiple‐input multiple‐output (MIMO) sonar applications. Increasing the number of transmitted signals helps improve the TDS‐based decorrelation performance. However, a large number of transmitters is not feasible for those sonar systems mounted on small platforms with limited space. To address the lack of TDS‐based degrees of freedom for smoothing, an improved TDS decorrelation method is proposed for MIMO sonar in this study. With the conjugated MIMO data covariance matrix being left‐multiplied and right‐multiplied, respectively, by the exchange matrix, the authors obtain a backward‐smoothed data covariance matrix. Afterwards, the authors average it with the original MIMO receiving data covariance matrix to reconstruct a new data covariance matrix. Compared with TDS, the improved TDS strengthens the decorrelation performance by increasing the number of covariance matrix for smoothing and thus enables the new rank restored signal covariance matrix to have better non‐singularity. Without increasing any aperture loss and system complexity, a lower correlation between echoes is obtained, and the performance of the minimum variance distortionless response beamformer is hence improved in the presence of coherent targets. The effectiveness of the proposed decorrelation method is verified by numerical simulations and real data from a water tank experiment.

This article employs corpus analysis to examine media representations of 'rural' in China Daily newspapers from 2001 to 2021, focusing on rural areas. Findings show that the rural social system in the twenty-first century is more diverse and complex than in the previous century. Economic development is the most frequently discussed factor in rural transformation development (RTD). Additionally, unlike the idyllic life described in previous studies, the Chinese news media are relatively objective and forthright about negative development issues.

Climate change impacts ecosystem, public health, food security, and economic development. The community-based adaptation and mitigation capacities of climate change should be strengthened through implementing Climate Village Program. This research aims to explore youth community as initiator, motivator and executor of Climate Village Program in Malangan Sukoharjo. Data collection was conducted using observation, in-depth interview and documentation in September–November 2021, data analysis using an interactive model, and data validity test using data source triangulation. Fifteen informants of research were Chairperson of Environmental Office of Sukoharjo, staffs of Malangan Village, advisor, head, Living Environment Division of Climate Village Program and Malangan villagers particularly youth community of Malangan Village. Result indicates Malangan villagers developing potential medicinal plants, ornamental plants, and livestock enthusiastically. Youth community actively initiates and motivates people through socializing Covid-19 prevention and management, applying healthy and clean life behaviour, including processing and utilizing rubbish actively through Reuse Reduce Recycle system and reforestation, constructing recharge areas to prevent flood, and planting big trees to improve family food resilience, energy resilience, and people welfare and to reduce emission. Inadequate knowledge on fish cultivation and plastic bottle rubbish processing constrains the implementation as the execution of Climate Village program.

The conversion of agricultural land for food in urban areas is a real threat to the region food security and availability. On the one hand, the livelihoods of farm workers are increasingly threatened, and it is easy to switch their livelihoods to other sectors. This study aims to examine the relationship between land conversion and farm laborers' household livelihood strategies to survive in urban areas. This study uses a mix methods approach to analyse relation between the macro data about land conversion rate data with the micro farm labor household livelihood strategy in West Java urban region. The results showed that the main livelihood for urban farm laborers could no longer be categorized, because of the fast and easy dynamics of transitioning from agricultural to non-agricultural livelihoods. This study also shows that the government's efforts are still not effective in suppressing the conversion of agricultural land to non-agricultural uses. The creation of new jobs based on urban agriculture is one solution that needs to be pursued to maintain food availability and the survival of urban farm workers.

Rimbawan(foresters) is one of the human resources owned by the Ministry of Environment and Forestry. They need to enhance their performance in decreasing forest fire areas. It will affect future public health, economic development, ecological balance, social stability, and land aesthetics. Accordingly, scenario planning helps in contemplating how the future may develop and is especially important when needing to make sense of uncertainty in the forest sustainability management sector. Scenario planning can be narrative-based and represented quantitatively to ensureRimbawan’sperformance level. On the other hand, promoting a more controllable forest fire area has not been fully anticipated. Therefore, this study aims to help environmental policymakers by offering a discovery of basic data for forest fire precautions, forest firefighting, and post-forest fire handling. This study has conducted a descriptively quantitative method. The results suggest that the average forest fire area in South Sumatra Province based on their KPH from 2015-to 2019 is 30.71 percent of those 2,265,457.34 hectares of KPH. Whereas the 1 level of an increase in forest fire prevention activities will reduce the probability of forest fire insight into the upscaledRimbawan’sperformance level through conversation quality and engagement, learning, decision-making style, mental models, and leadership support.

The objective of the present study was to determine yield performance and farmers' preference to the Lamuru composite corn variety planted with the application of corn Integrated Crop Management (ICM) and non Integrated Crop Management (non-ICM). The study was conducted in Kadumadang Village of Pandeglang Regency on a dry land agro-ecosystem in February-May 2020. The composite corn variety used was the Lamuru variety. Data was gathered using direct observation of agronomic performance and production with 10 replications. The agronomic data observed were plant height, number of leaves, stem diameter, 50% flowering age, cob length, cob diameter, number of rows per cob, 100 grains weight, stover weight, cob weight and dry seeds weight. Interviews and questionnaires were conducted to determine farmers' preference to the Lamuru variety performance. Quantitative data was analyzed statistically and qualitative data was analyzed descriptively. From the result, the growth of corn ICM was higher than non-ICM. It resulted in a higher productivity of corn ICM (9.27 t/ha) compared to non-ICM (6.68 t/ha) significantly. Furthermore, farmers gave a fairly high response to the performance of Lamuru variety through the application of corn ICM and non-ICM, respectively at 79.95% and 72.52%.

Nata de coco is a fermented product by Acetobacter xylium. The formation of nata requires a source of Carbon (C) and Nitrogen (N). The nitrogen used in the production such as Urea or Ammonium Sulfate (ZA) causes some people to feel reluctant to consume nata de coco. One of the natural protein sources that have high nitrogen content is Moringa Leaf (Moringa oleifera). The research aims to determine the appropriate concentration of Moringa leaf extract to obtain nata de coco with good physical properties and favored by consumers. The research method used was completely randomized design consisting of four replications and two treatments. The treatment consisted of concentration of Moringa leaf extract and Amonium Zulfat (ZA), which were concentrated as follows 2.5%, 5%, 7.5 % and 10%. Analysis was carried out on the yield, thickness, crude fiber, and organoleptic tests for the best treatment (color, aroma, taste and texture) from 20 semi-trained panelists. The results showed the treatment with 10% of Moringa leaves concentration and Amonium Zulfat (ZA) were the best treatment with yield of 85.11%, thickness 0.66 cm and crude fiber 17.26% and the organoleptic test score were 3-4 (neutral-like)

The corn plant is one of the most important food crops, in addition to wheat and rice. In addition to the main source of carbohydrates, it is also an alternative food corn is also grown as animal feed (forage and cob). One of the efforts that can be done to increase corn productivity, among others, by modifying plant growth such as pruning. The purpose of this study was to determine the effect of pruning leaves under the cob to increase corn production. Using a complete random design (RAL) consisting of 4 treatments (without pruning; 2-Leaf pruning; 4-Leaf pruning and 6-leaf pruning, each treatment is repeated 5 times. The results showed that the pruning of the lower leaves of the cob had no significant effect on the production components. In the treatment of 6 leaves pruning gives the highest production of 119.374 g, pruning 2 leaves 104.082 g, pruning 4 leaves 95.02 g and without pruning obtained 84.5 g. From this study it can be concluded that pruning up to 6 leaves under the cob has no effect on corn production. Pruning leaves under the cob at 65 days after planting has the potential to be used as quality animal feed
