title: <b>Supporting data for "Fourth Graders’ Literacy among Cities in the Greater Bay Area: An Investigation of Literacy Attainment, Socio-emotions and Strategy Use"</b>

description: The major impetus of this study is to undertake one of the first documentation efforts regarding the literacy performance of fourth graders across GBA cities. Additionally, the study seeks to enhance comprehension of students’ literacy achievement by examining the relationship between curriculum guidelines and literacy outcomes, specifically focusing on reading comprehension levels and writing proficiency dimensions.<br>The study includes 783 fourth-grade students from the GBA region, comprising 597 students (mean age = 10.37, 50.20% female) from three cities in Guangdong (Shenzhen, Guangzhou, Zhuhai) and 186 students (mean age = 10.07, 69.59% female) from Hong Kong. Literacy attainment is assessed through two reading comprehension tasks adopted from PIRLS and a continuation writing task developed by the researcher. Student questionnaires capture socio-economic status, socio-cognitive factors, and strategy use regarding reading and writing.The key findings reveal differences in literacy performance between Hong Kong and Guangdong students. Hong Kong students demonstrate superior skills in informational reading, while vice versa, Guangdong students excel in literary reading. Guangdong students are more advanced in higher-order processes involving integration and evaluation, such as comparing and contrasting information. In terms of writing performance, although the two regions’ students performed comparably overall, Guangdong students exhibit strengths in organization and linguistic expression. Regarding socio-cognitive factors, regression analyses showed intrinsic motivation is a significant predictor of Guangdong students’ reading performance, while extrinsic motivation is the significant predictor of Hong Kong students’ reading performance. Writing strategy use significantly predicted Guangdong students’ writing performance, but not Hong Kong.<br>Regarding curriculum analysis, both Hong Kong and mainland Chinese curriculum guidelines emphasize comprehensive language education and critical thinking skills. However, they differ in focus areas: the mainland Chinese curriculum prioritizes cultural confidence and specific language requirements, while the Hong Kong Chinese curriculum adopts a more holistic approach to language literacy, integrating broader educational goals and critical thinking development for a well-rounded education. Findings of the quantitative and qualitative data triangulate and corroborate each other.<br>These findings underscore the importance of understanding literacy attainment dynamics to inform curriculum implementation and instructional strategies. Moreover, they highlight the potential for enhancing educational communication and exchanges within the GBA, offering insights into Chinese literacy learning and instructional practices.<br>

title: Abundance of major meiofaunal taxa in upper intertidal accretion zones and supratidal salt marshes of the Island of Sylt, 1982 to 1983

description: From Sep 1982 to May 1983, the meiofauna in sheltered upper intertidal and supratidal habitats on Sylt island was quantitatively studied. Four sites were sampled in monthly intervals: two accretion sites (one vegetated and the other bare), and two salt marsh sites (one grazed and the other ungrazed). In the supratidal salt marshes, abundance of most taxa followed soil moisture with low abundance during the dry summer months and high abundance in winter and spring with high precipitation and frequent floodings by the sea. In the accretion zones seasonality was weak, presumably as a result of the addition of the winter/spring maxima in the landward salt marshes, and the summer/autum maximum in the seaward flats.

title: Platyhelminths and Acoelomorpha in upper intertidal accretion zones and supratidal salt marshes of the Island of Sylt, 1982 to 1983

description: In 1982 and 1983, sheltered upper intertidal and supratidal habitats on Sylt island were quantitatively studied for platyhelminths. This included (1) monthy sampling of two accretion sites, one vegetated and the other bare, and two salt marsh sites, one grazed and the other ungrazed; (2) seasonal sampling of 4 transects across salt marsh areas and accretion zones; and (3) some 50 sites sampled once only. In the accretion zone, the main factors stucturing platyhelminth assemblages were sediment type (sand or mud), the frequency of flooding as determined by tidal level (twice a day, during spring tides, or during storm floods only), and the density of vegetation. In supratidal salt marshes these factors were overruled by salinity and sediment humidity.

title: Supporting documents for 'BRD9 functions as an HIV-1 latency regulatory factor'

description: Despite decades of searching for a solution, AIDS remains largely incurable. A major challenge in achieving a complete cure for AIDS is the presence of HIV-1 reservoirs within the immune cell population of the host. The "Shock & Kill" strategy has been recently explored, which involves combining antiretroviral treatment (ART) with latency reversal agent (LRA) to reactivate HIV-1 latent reservoirs followed by eliminating infected cells through cell cytopathic effects and immune responses. However, current LRA treatments are not able to fully reactivate the HIV-1 latent reservoirs. To this end, investigation on novel HIV-1 latency regulator is crucial in addressing the persistent population of latently-infected cells. In this study, we identified BRD9, which belongs to the bromodomain and extra-terminal domain (BET) family, as a novel regulator of HIV-1 latency. Treatment with an BRD9 inhibitor, I-BRD9, induced HIV-1 latency reactivation in T cell line models, HIV-1-infected human resting memory CD4+ T cells, and peripheral blood mononuclear cells from people living with HIV-1 (PLWH) under ART treatment. Gene knockdown and protein degradation of BRD9 resulted in HIV-1 latency reactivation in T cell line. Additionally, BRD9 inhibition synergized with BRD4 inhibition in inducing HIV-1 viral production. Furthermore, we elucidated the underlying mechanisms of HIV-1 latency regulation by BRD9. We found that BRD9 binds to the HIV-1 genome at the LTR promoter and Gag gene region, suppressing HIV-1 gene transcription. Moreover, BRD9 competes with the HIV-1 Tat protein for binding to the HIV-1 genome. Through Cut&Run followed by DNA sequencing and RNA sequencing methods, we identified cellular pathways and downstream targets of BRD9 that can also modulate HIV-1 latency. ATAD2, MTHFD2, LDHB and BUB1B are novel BRD9 downstream genes and HIV-1 suppressing genes. Their inhibition can also reactivate HIV-1 latency and synergize with BRD9 inhibition in stimulating HIV-1 viral production.

title: Supporting data for Development of Electrospun Piezoelectric Materials for Dentistry

description: This study was dedicated to the development of electrospun piezoelectric flexible materials based devices for oral health detection and disease therapy. First, before the assembly, the preparation of electrospun PVDF-based piezoelectric composites was optimized in Chapter 4,, and the composites were characterized to obtain the optimal spinning parameters and fiber membrane processing parameters. Then, we introduced a new one-step bite force test method by using the principle of positive piezoelectric effect and electrospun piezoelectric materials as signal conversion media. In addition to developing a piezoelectric materials based bite force testing system, we also studied a self-powered oral energy harvesting device based on PENGs. After developing a wearable oral health device based on piezoelectric materials, we also conducted biocompatibility tests, including cell proliferation, viability and morphology, and metal ion precipitation.<br>The results revealed that factors such as the PVDF dissolve temperature, electrospinning voltage, volume ratio of the reagents in the solvent system, and ZrO<sub>2</sub> nanoparticle concentration can significantly affect the fiber morphology. ZrO<sub>2</sub> nanoparticle concentration, electrospinning voltage, membrane collector rotating speed, membrane annealing temperature, applied pressure and frequency can affect the piezoelectric output obviously. The PENGs based bite force testing system exhibited excellent accuracy and linearity, with a short operating procedure, making it an alternative to commercial bite force tests. Among the PENGs based aligner and mouthguard, the 2-layer mouthguard exhibited higher piezoelectric output, which provided the possibility for the realization of self-powered Photodynamic therapy (PDT). The extracts experiment results of the electrospun PVDF/ZrO<sub>2</sub> composites and electrospun PVDF-based PENG showed that<b> </b>the composites and piezoelectric oral devices showed good <i>in vitro</i> biocompatibility.

title: Pleuronectes platessa in the Sylt Rømø bight in 2015

description: Due to changing temperature regimes in the North- and the Wadden Sea, a fish survey in the Sylt Rømø bight (SRB) was established in 2007 for at least ten years. The aim is to investigate the Wadden Sea fish fauna with special interest in changes of migration behavior, species composition and feeding habits. Seven stations are sampled monthly inside the SRB. Two additional stations, one outside the bight, one close to the Danish border are sampled as references four times a year. For sampling a mini bottom trawl, total length 17 m, trawl opening 7 m, height 3 m with a mesh size of 36 mm in the wings, 16 mm in the mid part and 6 mm in the cod end is used. At every station one haul in the water column and another at the bottom are sampled, for 15 minutes at a speed of approximately 2 knots. The data will help to give a more detailed picture of food chains and energy flows inside the Wadden Sea.
