Abstract
Flotation tests were conducted on a low-grade refractory fluorite ore from Guizhou using tannin and sodium humate as carbonate depressants. The depressant effects of tannin and sodium humate in the flotation of carbonate-bearing fluorite ores were also investigated. The results showed that the mixed depressant of tannin and sodium humate had good depressant effect on carbonate under weak alkaline conditions. Through primary roughing, primary sweeping and flotation of four-stage concentrate of fluorite ore, qualified fluorite concentrate CaF2 with grade of 95.52% and recovery of 91.20% was obtained. Sodium humate has a good selective depressant effect on calcite. Tannic acid inhibits both fluorite and calcite. However, the selective depressant ability of tannins was best in the pH range of 6 to 8. Sodium humate and tannins are chemisorbed on mineral surfaces, and their adsorption capacity on calcite surfaces is greater than that of fluorite. The reaction products of sodium humate, tannin and calcium ions in solution interact with the organic compounds adsorbed on the calcite surface, forming a multilayer adsorption on the calcite surface and making the calcite more hydrophilic. Based on the density flood theory, Materials Studio ( MS) was used to calculate the relevant adsorption energies, and the results were obtained as follows: a. Compared to fluorite, tannin molecules and sodium humate molecules are more easily adsorbed on calcite surface; b. Compared to calcite alone, tannin molecules or sodium humate molecules adsorbed while the adsorption state will be more stable, and tannin and sodium humate synergistically inhibit calcite more effectively than the effect of depressant alone is better.

Abstract
Extreme weather events such as floods are becoming more frequent, and pose a substantial threat to Australia’s nearshore marine communities. In March 2021, a 450 km stretch of the eastern NSW coastline experienced a La Niña-related rainfall event over several days, resulting in large volumes of freshwater ingress to marine systems. Port Stephens, an estuary 250 km north of Sydney, recorded its highest week of rainfall on record. This was followed by two more flood events in March 2022 and June 2022. Prior to 2021, the marine-dominant eastern port of Port Stephens was home to the world’s largest aggregations of Dendronephthya australis, an Endangered species of soft coral endemic to the south-east coast of Australia. Using data from a 2019–2022 D. australis monitoring program in Port Stephens, spanning the unprecedented series of flood events in 2021-22, we detail the impacts of flood events on the population. Prior to the floods, aggregations of colonies were persisting, and individuals were growing at two of the four monitored sites. However, flooding in March 2021 caused a 91% decline in the remaining areal extent of D. australis. Modelling of likely causative factors highlighted water depth as the most significant environmental variable correlated with coral loss. Corals in shallower waters experienced lower salinity and were the most impacted. Continued monitoring during 2021 and 2022 documented the loss of all remaining aggregations in the estuary after further La Niña-related rainfall events, to the point where D. australis is now on the brink of localised extinction.
Imageless imagery in aphantasia: decoding non-sensory imagery in aphantasia
Authors: Meng Ming , Chang Shuai , Zhang Xinyu , Pearson Joel 
Published: August 2023

Abstract
Activity in early visual cortex is thought to tightly couple with conscious experience, including feedback-driven mental imagery. However, the state of mental imagery, what takes its place or how any activity relates to qualia in those with aphantasia (a complete lack of visual imagery) remains unknown. In the current study, univariate (amplitude) and multivariate (decoding) BOLD signals during imagery attempts were recorded in primary visual cortex. Unlike in those with imagery, neural signatures in those with validated aphantasia were ipsilateral and could not be cross-decoded with perceptual representations. Further, perception-induced neural activation was weaker in those with aphantasia compared to controls. Together, these data suggest that an imagery-related representation, but with less or transformed sensory information, exists in the primary visual cortex of those with aphantasia. Our data challenges the classic view that activity in primary visual cortex should result in sensory qualia.
On the Appearance of Action at a Distance
Authors: Willigenburg L. Gerard Van , Laidlaw Andrew 
Published: August 2023

Abstract
After forty years of EPR experiments, it appears on the face of the experimental facts that one of the oldest ideas in Physics has been falsified, namely the retarded interaction paradigm, the notion that long range interactions between quanta, or equivalently causal influences between point events, are mediated by physical entities - fields, particles or “causal influences” in general - that travel through space from one point to the other at or below the characteristic velocity, c. A critical examination of this basic idea shows it to be unsatisfactory in all respects. An alternative is then proposed that satisfies both causality and local action, “distributed action”, which is germane to local realist field models of the quanta, where matter and energy extend in space and interact locally and causally at all locations where they overlap. Bell Inequalities cannot be derived in this context because, with distributed fieldfield interactions, spacelike separation of events does not guarantee the fundamental “no influence” assumption from which all the various Bell Inequalities are derived. Distributed action thus explains what appears to us as instantaneous action at a distance.

Abstract
Liquid-liquid phase separation (LLPS) of biopolymers has recently been shown to play a central role in the formation of membraneless organelles with a multitude of biological functions1–3. Whether LLPS induces protein condensation and/or that associative interactions are required for LLPS is part of ongoing studies4,5. Biofilaments such as actin, amyloid fibrils, collagen and nanocellulose can form structured liquids or liquid crystals in vitro6–9. Here we present that the supramolecular polymerization of a variety of monomers is responsible for phase separation into anisotropic liquid droplets (tactoids) via an entropy-driven pathway. The crowding environment regulated by the concentration of dextran can influence not only supramolecular polymerizations but also properties of the LLPS, including phase separation kinetics, morphology, internal order, fluidity, and mechanical properties of the final tactoids. In addition, substrate-liquid and liquid-liquid interfaces were found to be able to accelerate the LLPS of supramolecular polymers, allowing the generation of a myriad of 3D-ordered structures, including highly ordered arrays of micrometer long tactoids at surfaces. The generality and many possibilities of supramolecular polymers to control emerging morphologies are shown with several supramolecular polymers, which opens a new area of matter ranging from highly structured aqueous solutions via stabilized LLPS to nanoscopic soft matter.

Published: August 2023

Abstract

Integrating the advantages of metal-organic framework (MOFs) and ionic covalent organic frameworks (iCOFs), a range of core-shell NH2-UIO-66@iCOFs (referred to as M@iCOFs) hybrid materials were fabricated by a straightforward condensation reaction of terephthalaldehyde and NH4Cl in the presence of NH2-UIO-66. These well-designed M@iCOFs, equipped with a NH2-UIO-66 as embedded CO2 adsorption engines, acquired significantly improved CO2 uptake and faster reaction rates, making them highly favorable for CO2 capture and conversion. Excellent yields of the various cyclic carbonates were obtained under 0.1 MPa of CO2 and solvent-free conditions. Moreover, the catalyst can also be recycled without significantly reducing the catalytic activity. This work presents a simple and effective method for constructing low-cost core-shell M@iCOFs hybrid materials with good CO2 adsorption and catalytic activity.

Abstract

With the rapid development of positioning and 5G technology, mobile objects in real life provide timely updates of location information, leading to the generation of large amounts of mobile data. However, the vast majority of mobile objects often move within a fixed spatial area, with only a few mobile objects leaving this area. If the single time-parameterized R-tree (TPR-tree) index structure is used, it will update frequently due to these “escaped” moving objects, thereby affecting the query efficiency. To address this issue, a hybrid index structure is proposed based on a three-dimensional (3D)-grid TPR-tree. A 3D grid is used to quickly locate and prune query points or regions in 3D space, and a global TPR-tree is applied to reduce the impact of the moving object update frequency on the query efficiency. The experimental results showed that the hybrid index structure based on the 3D-grid TPR-tree yielded good performances in both mobile queries and continuous k-nearest neighbor queries.

Published: August 2023

Abstract
Demand is increasing for photovoltaics (PVs) as a result of the development of the Internet of Things and edge computing technologies. As the lighting environment is different for the applications, thus, PVs must be adjustable to various light environments in which systems are installed. PVs should therefore be capable of easily changing their morphology without damaging the cells. To address this problem, in this work, a three-dimensional (3D) structure that increases power output under omnidirectional light was applied to a crystalline silicon solar cell array using a block-type method. The resultant block-type 3D indoor PV could operate a Bluetooth low-energy module in conjunction with a power management integrated circuit when the illuminance was 532 lux and 1620 lux and each PV installation area was 129.9cm2 and 32.48 cm2 respectively.

Abstract
Conventional dendritic cell (cDC1, cDC2) and plasmacytoid dendritic cell (pDCs) subsets have specialized functions that can be modulated by the tumor microenvironment (TME). These cells produce different interferons that are central to antitumor immune responses. While the role of Type I Interferons (IFN-I) in tumor immunity is well characterized, the role of Type III interferons (IFN-III) produced by cDC1 in the TME which is associated with good outcome remains completely unknown. Here, we demonstrate that IFN-III orchestrates pDCs survival, activation and TLR7 expression in the blood and in tumors, enhancing their capacity to respond to TLR7-ligand. Importantly, IFN-III prevents the inhibition of pDCs induced by the TME or by TGF-β, a dominant TME inhibitory cue, and restores their production of IFN-α. Because of the essential role of TGF-β in immune regulation, this mechanism is expected to impact other pathological situations.

Published: August 2023

Abstract
Background
Mobile clinics are important means of providing health care to underserved populations, especially during pandemics. The fifth generation (5G) network technology has the advantages of high transmission rate, ultra-low latency, large bandwidth and strong coverage, and is widely used in many medical scenarios. But there is no experience in combining 5G with mobile clinics. We aim to describe a mobile clinic solution that can quickly establish and provide medical care, as a reference for future public health emergencies.
Methods
We introduce the construction and function of a 5G-based mobile clinic. The practical experience in responding to the COVID-19 pandemic was described. The patient information was collected retrospectively, and the results were analyzed statistically.
Results
A total of 3,179 patients have received the services from the 5G-based mobile clinic. The mean age was 42.50 years, with 2,014 males and 1,165 females. Among them, 2,005 patients underwent nucleic acid screening and 872 underwent CT screening for COVID-19. Of these, 92.0% of patients were satisfied with the service.
Conclusion
The 5G-based mobile clinic can screen patients quickly and ensure the health of quarantined personnel. This is a mobile medical model worth trying and learning from. It provides practical experience for dealing with other major health emergencies in the future.

Abstract
Obsessive compulsive disorder (OCD) is a debilitating neuropsychiatric condition characterized by obsessions and compulsions. Despite the crucial role of the amygdala in anxiety, its role in OCD remains unclear. We found that the basolateral amygdala-dorsomedial striatum (BLA-DMS) circuit activation leads to the manifestation of OCD-related behaviors. We revealed that the BLA neurons projecting to the DMS, mainly onto dopamine D1 receptor-expressing neurons, largely overlap with the neuronal population that responds to aversive predator stress, a widely used anxiogenic stressor. Specific optogenetic activation of the BLA-DMS circuit induced a strong anxiety response followed by compulsive grooming. Furthermore, we developed a mouse OCD model displaying a wide spectrum of OCD-like behaviors by chronically activating the BLA-DMS circuit. In these mice, persistent molecular changes at the BLA-DMS synapses observed were causally related to the OCD-like phenotypes. Together, our study demonstrates the involvement of the BLA-DMS circuit in the emergence of enduring OCD-like compulsive behaviors via its persistent synaptic changes.

Abstract
Background: STH infections are public health problems in countries with poor sanitation coverage. However, there is a paucity of information on the epidemiological link between the environmental sample and helminth infection among farmers in Ethiopia. This aimed to investigate the load of STH in wastewater, soil, and the relationship between helminths in the environmental samples and farmers' stool in Ethiopia.
Methods: A cross-sectional study was conducted between November 2021 and February 2022 to determine the load of STH in environmental and farmer stool samples. A stratified random sampling technique was used to pick farming households. The sample size for each district was determined by a proportionate allocation to the number of households. From the wastewater-irrigated farm, 70 wastewater, 28 soil, and 86 farmers' stool samples were gathered and analyzed. A questionnaire was used to gather qualitative data, while environmental samples were used to generate quantitative data. Stata version 14 was used for data processing and analysis. The link between helminth in an environmental sample and the farmer's health was investigated using Poisson regression. Statistical significance was set at p < 0.05.
Results: The total load of STH eggs in the wastewater was 82.9 %, 57.1 % in the soil, and 18.6% in the farmers' stool. The concentration of Ascaris lumbricoides was found to be the highest in all investigated samples (wastewater 67 %, soil 25 %, and stool 10.5 %), followed by hookworm (wastewater 10 %, soil 21.4 %, and stool 6.9 %) and Trichuris trichiura eggs (wastewater 5.7 %, soil 10.7 %, and stool 1.2 %). The concentration of STH eggs in irrigation wastewater and agricultural soil showed a correlation with the infection in farmers', with a positive regression coefficient of 1.63 (95 % CI = 1.34 – 1.92) and 1.70 (95 % CI = 1.39 – 2.01) respectively. The association was statistically significant (p < 0.05).
Conclusion: Irrigating farmland with wastewater contaminated by STH eggs is a potential route for helminth infection among farmers. Therefore, an integrated approach is essential to address the problem in the area and prevent the spread of helminth infections.
Optimizing the appearance of plant-based foods using natural pigments and color matching theory
Authors: Wannasin Dawn , Grossmann Lutz K , McClements David Julian 
Published: August 2023

Abstract
The appearance of food significantly affects consumer’s buying decision. For plant-based foods, consumers expect them to have the same appearance, including color and opacity, as the animal-based products they replace. Therefore, matching the color of plant-based foods to their conventional animal-based counterparts could increase their acceptance by consumers. In this study, three plant-derived food colorants, red beet (red), turmeric (yellow), and butterfly pea flower (blue), were blended to match the color of raw meat, cooked meat, cooked whole egg, and cheddar cheese. Initially, the pigments were incorporated into three separate emulsions representing the three primary colors (red, yellow, and blue). The Kubelka-Munk and color matching theories were then used to determine the amount of each emulsion required to match the spectral reflectance of the animal-based products. Our results show that color matching theory could be used to formulate plant-based emulsions with similar optical properties to animal-based products, including chroma and lightness. However, some discrepancies were observed, which may have been due to differences in the scattering of light by the complex food matrices in animal-based products. The concept of blending three primary colors and color matching model developed in this study could be useful for the development of plant-based food products with improved appearances, thereby expanding their consumer appeal.

Abstract
In this paper, we studied the isolation and identification of 13 compounds extracted from the aerial parts of R. thymifolium. These compounds include: one terpenoid (1), one alkane (2), one fatty acid ethyl ester (3), one thiol (4), two fatty alcohols (5 and 7), two coumarins (6 and 10), two flavonoids (11 and 12), three aromatics (8, 9 and 13). Compound (1) was isolated from R. thymifolium for the first time. The isolated compounds were tested for insecticidal activity against T. castaneum, L. serricorne and D. destructor. Apocynin (8) and Acetophenone (13) exhibited obvious contact activity against the storage pests with LD50 values of 6.46 and 8.72 μg/adult respectively. Acetophenone (13) showed excellent contact activity against D. destructor with LC50 values of 0.08 mg/mL. The study clearly showed the active fractions from R. thymifolium have might potential to be developed into potential compounds on storage insect prevention.
Influence of climate change on vector born disease (Malaria) over India
Authors: Peri Subrahmanya Hari Prasad 
Published: August 2023

Abstract
Vector-borne diseases, such as malaria, pose a significant global threat, and their intensity is greatly influenced by climatological factors. Tropical countries, like India, are particularly vulnerable to such diseases, making accurate estimation of malaria risk crucial. In this study, we utilized the well-known Vector-borne Disease Community Model, VECTRI, developed by the International Centre for Theoretical Physics in Trieste. The model was implemented to estimate the Entomological Inoculation Rate (EIR) of malaria. Future climatic prediction datasets, including CMIP 5, along with population data sets, were used as inputs for the analysis. The projections covered the period from January 1, 2020, to December 31, 2029. The estimated EIR for the years 2020–2029 ranged from 90 to 100 bites per person per year. There was a noticeable decline in malaria risk over the coming decade. The months of August to November, during the post-monsoon period, were identified as highly prone to malaria transmission. Spatial analysis revealed that the east coast of India faced a higher vulnerability to malaria risk. The observed decline in malaria risk is a positive development, but it is essential to exercise caution, especially in areas with heavy rainfall. This research provides valuable insights for policy-makers, highlighting the need to implement future strategies to effectively mitigate malaria risk. By utilizing these findings, appropriate measures can be taken to combat the threat posed by malaria and protect public health.
