Learning Takes Flight: Empowering Growth through Dialogic Teaching in Individual Badminton Lessons
Authors: Chin Pauline P. L.
Published: September 2023

In the dynamic landscape of education, characterised by the need for resilience, the convergence of dialogic teaching and the passion for badminton presents a pathway to profound learning experiences. This article explores the intersection of these two realms, highlighting the invaluable insights and synergies they contribute within a robust educational framework. This qualitative investigation involves two experienced teachers and three Year 12 student athletes actively engaged in dialogic-based lessons. The data collection process encompasses recorded observations and interviews with the teachers and students and uses thematic analysis techniques to analyse the gathered information comprehensively. The findings reveal that dialogic teaching catalyses student engagement and growth, opens dialogues that stimulate metacognitive processes, promotes personal growth and respectful exchange of ideas, and extends the value of transferable skills beyond the court. The role of the teacher emerges as pivotal in shaping interactional behaviour and establishing an environment conducive to skill and knowledge acquisition. Through scaffolded dialogic interactions, students are guided towards critical thinking, enabling them to develop a more thorough understanding of the subject and refine their skills. The insights gained contribute to creating transformative learning experiences by promoting dialogue, resilience, and transferable skills, empowering students to excel in both badminton and their learning outcomes, preparing them for future challenges and fostering their holistic development.

Published: September 2023

A primary advantage to using reduced complexity climate models (RCMs) has been their ability to quickly conduct probabilistic climate projections, a key component of uncertainty quantification in many impact studies and multisector systems. Providing frameworks for such analyses has been a target of several RCMs used in studies of the future co-evolution of the human and Earth systems. In this paper, we present Matilda, an open-science R software package that facilitates probabilistic climate projection analysis, implemented here using the Hector simple climate model in a seamless and easily applied framework. The primary goal of Matilda is to provide the user with a turn-key method to build parameter sets from literature-based prior distributions, run Hector iteratively to produce perturbed parameter ensembles (PPEs), weight ensembles for realism against observed historical climate data, and compute probabilistic projections for different climate variables. This workflow gives the user the ability to explore viable parameter space and propagate uncertainty to model ensembles with just a few lines of code. The package provides significant freedom to select different scoring criteria and algorithms to weight ensemble members, as well as the flexibility to implement custom criteria. Additionally, the architecture of the package simplifies the process of building and analyzing PPEs without requiring significant programming expertise, to accommodate diverse use cases. We present a case study that provides illustrative results of a probabilistic analysis of mean global surface temperature as an example of the software application.
Truth by repetition across languages
Authors: De keersmaecker Jonas , Unkelbach Christian , Roets Arne
Published: September 2023

People are more likely to believe information to be true if they have encountered it before. Research on this truth-by-repetition effect (TBRE) typically only considered one’s native language. In five experiments (N = 1344), we examined the TBRE in multi-lingual contexts (Belgium, Spain, US, Mexico). We found that the TBRE emerges in the non-native language, and is as strong as the TBRE in the native language. Furthermore, we found a ‘cross-language’ TBRE: repetition increases the subjective truth even if the language changes between repetitions, and this cross-language effect is as strong as the effect within the same language, be it in a non-native or the native language. Theoretically, these results support TBRE accounts based on a conceptual mechanism. Practically, the results highlight the pervasive potential of the TBRE in a globalized world where many people consume information in different languages.
Opinions on Hard-to-Discuss Topics Change More via Cohort Replacement
Authors: Restrepo Ochoa Nicolas Restrepo , Vaisey Stephen
Published: September 2023

Cohort replacement---the replacement of older cohorts by their successors who developed under different conditions---is an important process driving cultural change. Research on public opinion in the United States indicates that most aggregate changes are best understood as the result of cohort replacement, rather than individuals changing their minds. However, some publicly salient sensitive issues, like gay rights, appear to be exceptions. Why exactly these issues appear to follow different trajectories of change it not well understood. A key reason is that previous work is limited by its focus on a single national context and the lack of a systematic comparison between more and less sensitive issues. We use data from the 1981-2020 World Values Surveys to compare aggregate changes in public opinion in 8 countries. We compare the trajectories of more sensitive and less sensitive issues to see if the pattern observed in the United States is generalizable. We find common trends – like changes in attitudes towards homosexuality – across most countries, as well as context-specific patterns that follow recognizable historical processes. An important insight is that sensitive issues seem to change more through cohort replacement. In short, issues that are difficult to talk about change more privately.

The authors initially employs the fast Fourier transform (FFT) approach to transforming voice inputs into digital signals before integrating a speech recognition solution (which includes two models: the hidden Markov model (HMM) and the artificial neural network (ANN)). To achieve standard-tone identification of voice signals and digitally store speech, the authors then incorporated a 2048-bit Rivest-Shamir-Adleman (RSA) encryption method to encrypt and decrypt digital speech. The authors’ building team constructed the program using a 256-bit advanced encryption standard - Galois counter mode (AES-GCM) encryption method to assure the application’s effectiveness. The authors successfully created a voice recognition application according to the HMM of ANN. The collected findings suggest that the authors’ secure speech recognition program (named soft voice - RSA) has improved in terms of safety, keeping speech material secret, and speed. It takes roughly 0.2 s to generate a 2048-bit RSA key pair that exceeds the National Institute of Standards and Technology (NIST) standard, 700-1070 ms to process speech, 1-4 ms to encrypt 2048-bit RSA, 6-8 ms to decrypt 2048-bit RSA.

A passive wireless sensor system integrated with capacitive fluidic flow detection is proposed and developed based on the printed circuit board (PCB) technique. The capacitive sensing structure consists of PCB-based electrodes enclosing an insulating pipe that contains the fluidic flow of interest. The conductivity of the fluidic flow and the appearance of foreign objects within the flow can be determined by analysing the resonant frequency of the detection path in the proposed system. Experimental results demonstrate that the resonant frequency increases according to the increase in electrical conductivity of the fluidic flow. In ad-dition, the sensing performance is also confirmed by the detection of sizes and electrical conductivities of NaCl droplets passing through the detection zone. Furthermore, this work indirectly verifies the effectiveness and feasibility of the integration of passive wireless sensing technique into the fluidic flow detector by using the PCB fabrication technique and demonstrates great potential for use in various applications in biomedical and chemical fields, especially in biomedical applications.

Published: September 2023

This study explored the growth and fermentation capabilities of four distinct yeast strains, including Saccharomyces cerevisiae var. boulardii CNCM I-745, S. cerevisiae 7012, S. cerevisiae 7028, and S. cerevisiae var. diastaticus BE-134, with the aim of identifying the most suitable strain for the production of a fermented beverage from soybean residue hydrolysate (SRH). The results were as follows: S. cerevisiae 7012 exhibited the most efficient fermentation, with residual sugar content of 2.16 g/100 ml, an ethanol concentration of 1.39% v/v, and a favourable aroma, receiving a sensory score of 4.3/5 points. Within this sensory profile, the aromatic compound 2-phenylethanol was found to be the predominant component. Additionally, S. cerevisiae var. boulardii CNCM I-745 demonstrated superior biomass production ability, achieving a cell density of 7.71 log CFU/ml after 48 hours of fermentation solution also showed the highest antioxidant activity, equivalent to 1.63 mg of ascorbic acid per 100 ml. Consequently, these two yeast strains were selected for combined use in fermentation to leverage the probiotic characteristics of S. cerevisiae var. boulardii CNCM I-745 and the flavouring capacity of S. cerevisiae 7012 in creating fermented beverages from SRH.

In this study, cellulose and hemicellulose were successfully extracted from pineapple leaf waste at yields of 58.8 and 16.1% by dried weight, respectively. Carboxymethyl cellulose (CMC) was synthesised from pineapple leaf cellulose by an esterification process using sodium hydroxide (NaOH) and monochloroacetic acid (MCA) with isopropanol as the supporting medium. Preparation of CMC was investigated by varying three free factors, namely, NaOH concentration, MCA dose, and cellulose size. The carboxymethylation process was optimised to produce CMC with differing degrees of substitution (DS). The highest DS of CMC (0.86) was obtained with 15% (w/v) NaOH solution, 0.6 g of MCA/g cellulose, and 50 μm cellulose. The obtained CMC were characterised by FTIR spectroscopy, SEM images and XRD diffractions. Moreover, the thickening performance of obtained CMC was also determined. The influence of the CMC’s molecular weight and degree of substitution on the viscosity of 1% (w/v) aqueous solution was tested. The experimental results suggest that the viscosity of the solution increases with increasing molecular weight and degree of substitution of CMC.

This study determined the most appropriate and earliest soybean harvesting stage and the number of days of postharvest ripening with minimal effects on seed losses and quality when mechanical harvest and threshing were applied. Harvesting stages at four physiological maturities (60, 70, 80, and 90%) and various days of postharvest ripening treatment (1, 2, and 3 days) were applied for two soybean varieties DT12 and DT26. Harvesting at physiological maturity of 90% recorded the highest seed-shattering loss but the least seed damage (<5%) and highest seed quality, followed by a physiological maturity of 80%. There were no significant differences in seed yields between harvesting stages of 80 and 90% maturity. Harvesting soybeans at a physiological maturity of 60 and 70% resulted in no seed losses but a significant reduction in seed quality. To avoid adverse weather, an early harvest stage at a physiological maturity of 80% is suggested. Although postharvest ripening of soybeans for early harvest caused seed shattering losses (2-5%), it was necessary to ensure seed quality. These results indicate effective and practical methods for farmers at small households to use in early mechanical harvesting of soybeans.

A prospective, descriptive study was conducted on 382 pediatric patients diagnosed with pertussis at Vietnam National Children’s Hospital over a two-year period, from January 1st, 2019, to December 31st, 2020. Of all patients participating in this study, children with severe conditions accounted for 30.1% (115/382). Several factors were found to be associated with the risk of this condition with odds ratios (OR) and 95% confidence intervals (CI), including a decrease in the duration of the onset phase by 5 days [OR 1.53, 95% CI: 1.002-2.34], fever [2.49, 1.18-5.24], cyanosis [9.59, 2.9-31.7], pneumonia [14.45, 6.06-34.5], pulmonary hypertension [4.15, 1.02-16.83], an increase of 10 g/l in white blood cell (WBC) count in the full blood count (FBC) test [1.39, 1.05-1.84], a 5-cycle reduction in Cycle threshold (Ct) value in the pertussis real-time PCR test [1.36, 1.01-1.84], and superinfection [3.94, 1.84-8.48 times]. A WBC count in FBC of ≥30 g/l could be used as a prognostic factor for the risk of severe illness condition (sensitivity 46.1%, specificity 90.6%), the requirement for mechanical ventilation (sensitivity 57.1%, specificity 88.5%), and mortality (sensitivity 100%, specificity 91%).

Exploring Socio-Political Dimensions of Heritage Language Maintenance: The Case of Vietnamese Speakers in Montréal
Authors: Nina Le Thao-Nguyen , Trofimovich Pavel
Published: September 2023

Research on heritage language (HL) development often focuses on immigrants’ identity and social network as predictors of HL maintenance. However, an important and overlooked factor is the socio-political circumstances that trigger emigration, such as whether immigrants relocate due to economic hardship or political turmoil. This study examines if the pattern of HL maintenance and its association with immigrants’ ethnolinguistic identity and social engagement differ for families of political versus economic immigrants. Participants were 38 parent–child pairs from Montreal’s Vietnamese diaspora. The parents identified their reason for immigration and completed an ethnolinguistic questionnaire, their children provided a HL communication profile, and all participated in interviews. To determine participants’ Vietnamese speaking skills, short interview excerpts were rated for accentedness, comprehensibility, fluency, and global knowledge. Participants were generally successful at maintaining their HL, but there was a decline in the children’s Vietnamese, especially for the economic immigrants. Several ethnolinguistic variables (desire to preserve a HL, pride in heritage culture) and social network properties (network size, intimacy, communication-related stress) appeared to contribute to HL maintenance. However, these relationships were different (and sometimes opposite) in the groups of political versus economic immigrants, suggesting that HL development and maintenance are subject to various contextual influences.

Published: September 2023

Three-dimensional (3D) printing is a new method of creating anatomical models, which can enhance the training of students and health professionals. The large breed-variation in dogs means that interpretation of thoracic radiographs can be challenging for the inexperienced radiologist. The aim of this study was to develop digital and printed 3D cardiac models from six canine breeds and evaluate their use as a tool for studying breed variations in radiology. The printed and digital 3D cardiac models were used by postgraduate veterinary students in diagnostic imaging along with a theoretical class on the subject and students completed a pre- and post-test, assessing cardiac size on thoracic radiographs in order to verify the usefulness of the models. The students then completed a satisfaction questionnaire on a Likert scale. There was a significant difference between the pre-test and the post-test results, with greater accuracy after using the 3D models. More errors were made in pre-test interpretation of radiographs from English Cocker Spaniel, English Bulldog, and Yorkshire Terrier and there were a significantly higher number of correct answers after using the 3D models. The vast majority of responses to all questions in the satisfaction questionnaire were positive, with partial or total agreement of the participants. This study demonstrates that digitally printed cardiac models from different breeds of dogs are effective learning tools. They helped students to better understand the relevant spatial relationship and cardiac morphology and to compare this anatomy with the radiographic image. Models are provided in 3D PDF and STL files for download.

Published: September 2023

In the interaction of molybdenum and tungsten with 2-hydroxy-5-halogenthiophenols, mixed-ligand complexes (MLC) extractable with chloroform are formed. Aniline, N-methylaniline, and N, N-dimethylaniline were used as the hydrophobic amines. The conditions for the extraction-photometric determination of molybdenum and tungsten are found. The best extractants were chloroform, dichloroethane and carbon tetrachloride. In a single extraction with chloroform, 97.8–98.2% of molybdenum and tungsten are recovered in the form of MLC (in the case of C2H4Cl2 and CCl4, 95–96% of molybdenum and tungsten are recovered). Molybdenum and tungsten MLC extracts obey the basic law of light absorption at concentrations of 0.2–20 and 0.2–19 μg/mL, respectively. It was established by the Nazarenko method that the complexing form of molybdenum and tungsten is MeO (OH)2+. It was found that MLC are formed at pHopt. 1.8-5.1. The maximum in the light absorption spectrum is observed at 457–538 nm. The molar light absorption coefficient is (3.2-4.2) ×104. It has been proven that molybdenum (VI) and tungsten (VI) are reduced to Me(V) by the reagent itself upon formation of a complex with halothiophenols.

Impact of Adjuvant Gemcitabine Containing Chemotherapy Following Radical Nephroureterectomy for Patients with Upper Tract Urothelial Carcinoma: Results from a Propensity-Score Matched Cohort Study
Authors: Hongda Zhao , Kang Liu , Ng Chi-Fai , de la Rosette Jean , Laguna Pilar , Gontero Paolo , Baard Joyce , Yildiz Ozcan , Teoh Jeremy Yuen-Chun
Published: September 2023

BACKGROUND:

The evidence regarding perioperative adjuvant chemotherapy and personalized surveillance strategies for upper tract urothelial carcinoma is limited.

OBJECTIVE:

To evaluate whether adjuvant gemcitabine containing chemotherapy affects the oncological outcomes of advanced upper tract urothelial carcinoma (UTUC).

METHODS:

The CROES-UTUC registry is an observational, international, multi-center study on patients diagnosed with UTUC. Patient and disease characteristics from 2380 patients with UTUC were collected, and finally 738 patients were included in this analysis. The primary outcome of this study was recurrence-free survival. Propensity score matching was performed. Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to the treatment of adjuvant chemotherapy.

RESULTS:

A total of 738 patients were included in this analysis, and 59 patients received adjuvant chemotherapy (AC), including 50 patients who received gemcitabine. A propensity score matching was performed, including 50 patients who received gemcitabine containing treatment and 50 patients without adjuvant chemotherapy. Disease recurrence occurred in 34.0% of patients. The recurrence rate in the AC group was 22.0%, which was significantly lower than the non-AC group (46.0%). Kaplan-Meier analyses also showed that AC was associated with a lower likelihood of tumor recurrence ( p = 0.047). However, AC was not significantly associated with a higher overall survival (OS) ( p = 0.908) and cancer-specific survival (CSS) ( p = 0.979). Upon multivariate Cox regression analysis, AC was associated with a lower risk of tumor recurrence (HR = 0.297, p = 0.028).

CONCLUSION:

The present study confirms that adjuvant gemcitabine containing chemotherapy could decrease the risk of tumor recurrence in patients with locally advanced UTUC following nephroureterectomy. However, more studies are need to draw a clearer image of the value of this treatment method.

BACKGROUND: Knee osteoarthritis (OA) is a common and disabling disease among the elderly population. The optimal conservative treatment for knee OA is not well established. OBJECTIVE: This study aimed to assess the effectiveness of pulsed electromagnetic field (PEMF) combined with progressive resistance exercise (PRE) in improving physical function and pain in patients with knee OA. METHODS: Thirty-four patients with knee OA (17 in each group) participated in a single-blind randomized control study. Patients were randomly assigned to receive 24 sessions of either combined PEMF and PRE (treatment group) or PRE only (control group). Patients were evaluated at pre-treatment, post-treatment (2 months), and at 3-month and 6-month follow-ups using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Numeric Pain Rating Scale (NPRS); walking speed and 5-times chair stand test. Mixed ANOVA was used for statistical analysis with Bonferroni adjustments. RESULTS: There was no significant group-by-time interaction for any outcome (P> 0.05). However, both groups scored significantly higher on the NPRS and KOOS at post-treatment, 3-, and 6-month follow-up compared to their baseline. Further, both groups completed the 5-times chair stand test and walking speed test with significantly less time at all post-treatment time points than the pre-treatment. None of the study outcomes (NPRS, KOOS, walking speed, and 5 times chair stand) were significantly different between groups at any of the time points. CONCLUSION: Both treatment options, PRE only versus PRE with PEMF, were equally effective in decreasing pain and improving physical function in patients with knee OA. This would suggest that the optimal parameters for PEMF that may show beneficial effects for knee OA when added to PRE training need to be determined.

Authors: Kim Jinhong , Cho Juchul
Published: September 2023

BACKGROUND: Although mulligan sustained natural apophyseal glides (SNAG) and maitland mobilization (MM) are common interventions for musculoskeletal disease, no study has directly compared the effectiveness of mid-thoracic spine mobilization in subacute stroke patients. OBJECTIVE: To investigate the effects of mid-thoracic spine mobilization (SNAG vs. MM) on postural balance and gait ability in subacute stroke patients. METHODS: Fifty subacute stroke patients were randomly allocated to the SNAG (n= 17), MM (n= 16), and control (n= 17) groups, each receiving a neuro-developmental therapy program for four successive weeks. The SNAG and MM groups additionally received mid-thoracic spine mobilization (T4∼8). The primary outcome measure was postural sway, and secondary outcome measures included the five times sit-to-stand test (FTSST), functional reach test (FRT), 10-m walk test (10MWT), 6-minute walk test (6MWT) and global rating of change (GRC). RESULTS: Participants reported no adverse events, and there was no loss to follow-up. The SNAG and MM group patients demonstrated significant improvements (p< 0.05) in postural sway, FTSST, FRT, 10MWT, and 6MWT compared with those in the control group, with no between-group differences. CONCLUSIONS: Mid-thoracic spine mobilization allows significant improvements in postural balance and gait ability in subacute stroke patients, with no differences between the SNAG and MM techniques.

Published: September 2023

Recommendation systems are an effective solution to deal with information overload, particularly in the e-commerce sector, in which sequential recommendation is extensively utilized. Sequential recommendations aim to acquire users’ interests and provide accurate recommendations by analyzing users’ historical interaction sequences. To improve recommendation performance, it is vital to take into account the long- and short-term interests of users. Despite significant advancements in this domain, some issues need to be addressed. Conventional sequential recommendation models typically express each item with a uniform embedding, ignoring evolutionary patterns among item attributes, such as category, brand, and price. Moreover, these models often model users’ long- and short-term interests independently, failing to adequately address the issues of interest drift and short-term interest evolution. This study proposes a new model, the Feature-aware Long-Short Interest Evolution Network (FLSIE), to address the above-mentioned issues. Specifically, the model uses explicit feature embedding to represent item attribute information and employs a two-dimensional (2D) attention mechanism to distinguish the significance of individual features in a specific item and the relevance of each item in the interaction sequence. Furthermore, to avoid the issue of interest drift, the model employs a long-term interest guidance mechanism to enhance the representation of short-term interest and adopts a gated recurrent unit with attentional update gate to model the dynamic evolution of users’ short-term interest. Experimental results indicate that our presented model outperforms existing methods on three real-world datasets.
Citizen-centricity in digital government research: A literature review and integrative framework
Authors: Sundberg Leif , Holmström Jonny
Published: September 2023

Citizen-centricity is a common concept in digital government research and policy. However, there is little clarity regarding the concept in previous literature. To address this shortcoming, and build theoretical foundations for addressing both citizen-centricity and associated phenomena, we have examined how citizen-centricity is characterized in digital government research. This study is based on literature review of 66 journal articles. A combination of narrative analysis and ideal-type methodology identified themes concerning four modes of government, designated traditionalist, service-dominant, participatory, and transformative. Further analysis of associated types and research streams provides an overview of the theoretical understandings of citizen-centricity and methodological approaches applied to explore it in the literature. The findings contribute to contemporary theory on citizens in digital government by outlining an integrative framework of citizen-centricity. The paper concludes with proposals for further research, including efforts to enhance conceptual clarity and develop more dynamic theories.

Published: September 2023

Background: The Alzheimer’s Disease Anti-inflammatory Prevention Trial (ADAPT) was the first-ever large-scale anti-inflammatory prevention trial targeting Alzheimer’s disease. Objective: The overall goal of this study was to evaluate predictive blood biomarker profiles that identified individuals most likely to be responders on NSAID treatment or placebo at 12 and 24 months. Methods: Baseline (n = 193) and 12-month (n = 562) plasma samples were assayed. The predictive biomarker profile was generated using SVM analyses with response on treatment (yes/no) as the outcome variable. Results: Baseline (AUC = 0.99) and 12-month (AUC = 0.99) predictive biomarker profiles were highly accurate in predicting response on Celecoxib arm at 12 and 24 months. The baseline (AUC = 0.95) and 12-month (AUC = 0.9) predictive biomarker profile predicting response on Naproxen were also highly accurate at 12 and 24 months. The baseline (AUC = 0.93) and 12-month (AUC = 0.99) predictive biomarker profile was also highly accurate in predicting response on placebo. As with our prior work, the profiles varied by treatment arm. Conclusions: The current results provide additional support for a precision medicine model for treating and preventing Alzheimer’s disease.
RhoA-LIMK Signaling Axis Reveals Rostral-Caudal Plane and Spatial Dysregulation in the Brain of Alzheimer’s Disease Mouse Models
Authors: Nik Akhtar Shayan , Lu Qun
Published: September 2023

Background: RhoA signaling is widely reported to be dysregulated in Alzheimer’s disease (AD), but its therapeutic targeting demonstrated mixed outcomes. We hypothesize that the activation and inactivation states of RhoA and LIMK are different in the cortex and in subregions of hippocampus along the rostral-caudal dimensions. Objective: We intended to elucidate the plane and spatial dependent RhoA signaling in association with AD. Methods: We applied antibody pRhoA that recognizes an inactive state of RhoA (S188 phosphorylation) and antibody pLIMK against an active state of LIMK (T508 phosphorylation) to investigate RhoA signaling in wildtype (WT) and triple transgenic AD (3xTg-AD) mouse model. We prepared serial sections from the rostral to caudal coronal planes of the entire mouse brain followed by immunofluorescence staining with pRhoA and pLIMK antibodies. Results: Both pRhoA and pLIMK elicited a shift of expression pattern from rostral to caudal planes. Additionally, pRhoA demonstrated dynamic redistribution between the nucleus and cytoplasm. pLIMK did not show such nucleus and cytoplasm redistribution but the expression level was changed from rostral to caudal planes. At some planes, pRhoA showed an increasing trend in expression in the cortex but a decreasing trend in the dentate gyrus of the 3xTg-AD mouse hippocampus. pLIMK tends to decrease in the cortex but increase in the dentate gyrus of 3xTg-AD mouse hippocampus. Conclusions: RhoA activation is dysregulated in both human and mouse AD brains, and the RhoA-LIMK signaling axis reveals spatial dysregulation along the rostral-caudal plane dimensions.

Background: Multiple studies have reported brain lipidomic abnormalities in Alzheimer’s disease (AD) that affect glycerophospholipids, sphingolipids, and fatty acids. However, there is no consensus regarding the nature of these abnormalities, and it is unclear if they relate to disease progression. Objective: Monogalactosyl diglycerides (MGDGs) are a class of lipids which have been recently detected in the human brain. We sought to measure their levels in postmortem human brain and determine if these levels correlate with the progression of the AD-related traits. Methods: We measured MGDGs by ultrahigh performance liquid chromatography tandem mass spectrometry in postmortem dorsolateral prefrontal cortex gray matter and subcortical corona radiata white matter samples derived from three cohorts of participants: the Framingham Heart Study, the Boston University Alzheimer’s Disease Research Center, and the Arizona Study of Aging and Neurodegenerative Disorders/Brain and Body Donation Program (total n = 288). Results: We detected 40 molecular species of MGDGs (including diacyl and alkyl/acyl compounds) and found that the levels of 29 of them, as well as total MGDG levels, are positively associated with AD-related traits including pathologically confirmed AD diagnosis, clinical dementia rating, Braak and Braak stage, neuritic plaque score, phospho-Tau AT8 immunostaining density, levels of phospho-Tau396 and levels of Aβ40. Increased MGDG levels were present in both gray and white matter, indicating that they are widespread and likely associated with myelin-producing oligodendrocytes—the principal cell type of white matter. Conclusions: Our data implicate the MGDG metabolic defect as a central correlate of clinical and pathological progression in AD.

Published: September 2023

Code-based algorithms are crucial tools in the detection of dementia using electronic health record data, with broad applications in medical research and healthcare. Vassilaki et al.’s study explores the efficacy of code-based algorithms in dementia detection using electronic health record data, achieving approximately 70% sensitivity and positive predictive value. Despite the promising results, the algorithms fail to detect around 30% of dementia cases, highlighting challenges in distinguishing cognitive decline factors. The study emphasizes the need for algorithmic improvements and further exploration across diverse healthcare systems and populations, serving as a critical step toward bridging gaps in dementia care and understanding.
Identity-based proxy blind signature scheme on lattice in high-speed network environment
Authors: Yang Mengjiao , Ke Dongmei , Li Fengyin
Published: September 2023

The methods of network attacks are becoming more and more diverse In high-speed networks, and protecting private data is a key issue for users’ security. Proxy blind signature technology combines proxy and blind signature technology to achieve signature transitivity and message confidentiality. However, current signature schemes will not be secure in quantum environments. Meanwhile, the certificate storage of the existing scheme is relatively complicated. Therefore, to avoid the need for certificates and resist quantum attacks, this paper proposes an anti-quantum identity-based proxy blind signature (ID-Proxy-BS) scheme on lattice. This ID-Proxy-BS scheme improves the efficiency of signature through Gaussian distribution and sampling techniques. Security analysis shows that the scheme satisfies correctness, efficiency, blindness, and unforgeability.
