Abstract	Promoting local food systems is crucial to providing a more viable economy, eco-friendly production, and equal opportunities for producers, consumers, and communities. Meat processors are critical to local meat producers and the meat supply chain. However, various barriers have restricted small-scale meat processors and challenged the local meat supply chain. Although local food systems have gained enormous scholarly attention, little attention has been devoted to specifically exploring the meat processing sector. This study investigated the characteristics and challenges of small-scale (<750 employees) and very-small–scale (<200 employees) meat processors in Missouri. Twenty-six meat processors participated in an online survey through Qualtrics, a mail survey, or a structured phone interview between May 2021 and March 2022. We identified the characteristics and constraints related to their businesses. The analysis revealed that 76% of meat processors perceived that their business was in better or much better condition than before the COVID-19 pandemic, reflecting their adaptability to the disrupted meat supply chain. However, small-scale meat processing facilities were limited by the labor shortage, complicated regulations and high regulatory compliance costs, a lack of consistent supply, and limited access to tools and equipment. More integrated work is needed to aid smaller processors in positively impacting the local community and environment through locally sourced meat production. This study contains helpful implications for state-level policymaking, extension programs, and future research directions.

Abstract	Investing in the agricultural sector exposes producers to numerous risks and uncertainties. The COVID-19 pandemic exacerbated these challenges, and their impacts are still being felt globally. Our study aims to evaluate and describe the risk management strategies employed by small farmers in Missouri to mitigate and adapt to the impact of the COVID-19 pandemic on their farm operations. We analyzed 141 survey responses, and our findings indicate that most respondents employed multiple strategies, including using savings, diversification, reducing inputs, donating output, delaying investment, gaining off-farm employment, and utilizing government relief programs. However, apart from the COVID-19 stimulus checks, which were automatically disbursed to eligible households, few farmers were aware of or participated in other federal relief programs aimed at supporting small businesses and producers. We recommend that Extension specialists collaborate with other stakeholders and agencies responsible for federal relief programs to enhance small farmer awareness and participation in the future. Additionally, further research is necessary to understand the coping strategies employed by small farmers to remain resilient and maintain personal and mental health during the pandemic.

Abstract	Abstract Background The COVID‐19 pandemic has created challenges with respect to HIV care services. Remote online services might provide an effective method for health service delivery to people living with HIV (PLHIV). Few studies have focused on the efficacy of telemedical services for PLHIV and the effect of antiretroviral treatment via online services in China. Methods We developed a platform called the “No. 8 Health” for online antiretroviral drug collection and delivery services in Beijing from January 21 to June 30, 2022. We evaluated the online treatment service according to viral load suppression rates and compared differences in social characteristics between PLHIV who received antiretroviral drugs through online or offline treatment services. Results By June 2022, 9528 PLHIV had received outpatient treatment services, among which 44.6% (4031/9528) used the online treatment and drug delivery services for a total of 5590 person‐times. The satisfaction rate was 100%. Rates of viral load suppression among PLHIV who initiated antiretroviral therapy (ART) in 2020 and 2021 were 96.4% and 93.1%, respectively. Results showed that the viral load suppression rate was 97.9%. Regarding HIV rapid self‐testing, 4513 men who have sex with men used the online HIV rapid testing service. The number of users was approximately the same as in 2021, but both were slightly lower than those in 2020. Conclusion This study was the first to evaluate the effect of online drug collection and delivery services and virologic outcomes among PLHIV in China. The online service helped with maintenance of ART services, but the COVID‐19 pandemic still had some impacts on viral load suppression.

Abstract	The discipline of land change science has been evolving rapidly in the past decades. Remote sensing played a major role in one of the essential components of land change science, which includes observation, monitoring, and characterization of land change. In this paper, we proposed a new framework of the multifaceted view of land change through the lens of remote sensing and recommended five facets of land change including change location, time, target, metric, and agent. We also evaluated the impacts of spatial, spectral, temporal, angular, and data-integration domains of the remotely sensed data on observing, monitoring, and characterization of different facets of land change, as well as discussed some of the current land change products. We recommend clarifying the specific land change facet being studied in remote sensing of land change, reporting multiple or all facets of land change in remote sensing products, shifting the focus from land cover change to specific change metric and agent, integrating social science data and multi-sensor datasets for a deeper and fuller understanding of land change, and recognizing limitations and weaknesses of remote sensing in land change studies.

Abstract	Dynamic Searchable Symmetric Encryption for Multiuser (M-DSSE) is an advanced form of symmetric encryption. It extends the traditional symmetric encryption to support the operations of adding and deleting the encrypted data and allow an authenticated group of data users to retrieve their respective desired encrypted data in the dynamic database. However, M-DSSE would suffer from the privacy concerns regarding forward and backward security. The former allows an attacker to identify the keywords contained in the added data by lunching file-injection attacks, while the latter allows to utilize the search results and the deleted data to learn the content. To our knowledge, these privacy concerns for M-DSSE have not been fully considered in the existing literatures. Taking account of this fact, we focus on the dynamic searchable symmetric encryption for multiuser meeting the needs of forward and backward security. In order to propose a concrete scheme, the primitives of Pseudorandom Functions (PRF) and the Homomorphic Message Authenticator (HMAC) are employed to construct the inverted index and update the search token. The proposed scheme is proven secure in the random model. And the performance analysis shows that the proposed scheme achieves the enhanced security guarantees at the reasonable price of efficiency.

Abstract	Aim: To explore the correlation of gut microbiota and the metabolites with the progression of diabetic retinopathy (DR) and provide a novel strategy to elucidate the pathological mechanism of DR. Methods: The fecal samples from 32 type 2 diabetes patients with proliferative retinopathy (PDR), 23 with non-proliferative retinopathy (NPDR), 27 without retinopathy (DM), and 29 from the sex-, age- and BMI- matched healthy controls (29 HC) were analyzed by 16S rDNA gene sequencing. Sixty fecal samples from PDR, DM, and HC groups were assayed by untargeted metabolomics. Fecal metabolites were measured using liquid chromatography-mass spectrometry (LC-MS) analysis. Associations between gut microbiota and fecal metabolites were analyzed. Results: A cluster of 2 microbiome and 12 metabolites accompanied with the severity of DR, and the close correlation of the disease progression with PDR-related microbiome and metabolites were found. To be specific, the structure of gut microbiota differed in four groups. Diversity and richness of gut microbiota were significantly lower in PDR and NPDR groups, than those in DM and HC groups. A cluster of microbiome enriched in PDR group, including Conclusion: This study elaborates the different microbiota structure in the gut from four groups. The relative abundance of

Abstract	This study aimed to generate interspecific hybrids between two remote lily species, L. hansonii Leichtlin and L. brownii var. colchesteri . Reciprocal crosses were performed by conventional and cut-style pollination methods, but viable seeds were only obtained when L. hansonii was used as the female parent, indicating that unilateral incompatibility exists between the two species. In the case of immature seeds, embryos with 2~3 mm were carefully removed from testa for further in vitro culture, and they grew as normal plants. A total of 343 progenies was obtained from the crosses, and hybridity of the progenies were examined using the L9 marker, simple sequence repeat (SSR) marker, at the seedling stage and 92 were confirmed as F 1 hybrids. Ploidy level of 76 F 1 hybrid was examined and confirmed as diploid. F 1 hybrids exhibited intermediate morphologies of the parent in outer tepal and leaf length, but flower shape and color were similar to those of L. hansonii . On the other hand, F 1 hybrid plants showed increased flower spots, flower size, and bud numbers, which could be important signatures of the F 1 hybrid. This study reports the first attempt to generate an interspecific hybrid between the two species, and therefore, our results from this study would be very informative for future lily breeding.

Abstract	Motivated by the recent successful synthesis of Janus monolayer of transition metal (TM) dichalcogenides, MXenes with Janus structures are worthy of further study, concerning its electronic structure and magnetic properties. Here, we study the effect of different transition metal atoms on the structure stability and magnetic and electronic properties of M’MCO 2 (M’ and M = V, Cr and Mn). The result shows the output magnetic moment is contributed mainly by the d orbitals of the V, Cr, and Mn atoms. The total magnetic moments of ferromagnetic (FM) configuration and antiferromagnetic (AFM) configuration are affected by coupling types. FM has a large magnetic moment output, while the total magnetic moments of AFM2’s (intralayer AFM/interlayer FM) configuration and AFM3’s (interlayer AFM/intralayer AFM) configuration are close to 0. The band gap widths of VCrCO 2 , VMnCO 2 , CrMnCO 2 , V 2 CO 2 , and Cr 2 CO 2 are no more than 0.02 eV, showing metallic properties, while Mn 2 CO 2 is a semiconductor with a 0.7071 eV band gap width. Janus MXenes can regulate the size of band gap, magnetic ground state, and output net magnetic moment. This work achieves the control of the magnetic properties of the available 2D materials, and provides theoretical guidance for the extensive design of novel Janus MXene materials.

Abstract	Abstract Introduction People living with HIV (PLHIV) relied on community-based organizations (CBOs) in accessing HIV care and support during the COVID-19 pandemic in China. However, little is known about the impact of, and challenges faced by Chinese CBOs supporting PLHIV during lockdowns. Methods A survey and interview study was conducted among 29 CBOs serving PLHIV in China between November 10 and November 23, 2020. Participants were asked to complete a 20-minute online survey on their routine operations, organizational capacity building, service provided, and challenges during the pandemic. A focus group interview was conducted with CBOs after the survey to gather CBOs’ policy recommendations. Survey data analysis was conducted using STATA 17.0 while qualitative data was examined using thematic analysis. Results HIV-focused CBOs in China serve diverse clients including PLHIV, HIV high-risk groups, and the public. The scope of services provided is broad, ranging from HIV testing to peer support. All CBOs surveyed maintained their services during the pandemic, many by switching to online or hybrid mode. Many CBOs reported adding new clients and services, such as mailing medications. The top challenges faced by CBOs included service reduction due to staff shortage, lack of PPE for staff, and lack of operational funding during COVID-19 lockdowns in 2020. CBOs considered the ability to better network with other CBOs and other sectors (e.g., clinics, governments), a standard emergency response guideline, and ready strategies to help PLHIV build resilience to be critical for future emergency preparation. Conclusion Chinese CBOs serving vulnerable populations affected by HIV/AIDS are instrumental in building resilience in their communities during the COVID-19 pandemic, and they can play significant roles in providing uninterrupted services during emergencies by mobilizing resources, creating new services and operation methods, and utilizing existing networks. Chinese CBOs’ experiences, challenges, and their policy ...
