Personal video recorders (PVRs) have altered the way users consume television (TV) content by allowing users to record programs and watch them at their convenience, overcoming the constraints of live broadcasting. However, standalone PVRs are limited by their individual storage capacities, restricting the number of programs they can store. While online catch-up TV services such as Hulu and Netflix mitigate this limitation by offering on-demand access to broadcast programs shortly after their initial broadcast, they require substantial storage and network resources, leading to significant infrastructural costs for service providers. To address these challenges, we propose a collaborative TV content recording system that leverages distributed PVRs, combining their storage into a virtual shared pool without additional costs. Our system aims to support all concurrent playback requests without service interruption while ensuring program availability comparable to that of local devices. The main contributions of our proposed system are fourfold. First, by sharing storage and upload bandwidth among PVRs, our system significantly expands the overall recording capacity and enables simultaneous recording of multiple programs without the physical constraints of standalone devices. Second, by utilizing erasure coding efficiently, our system reduces the storage space required for each program, allowing more programs to be recorded compared to traditional replication. Third, we propose an adaptive redundancy scheme to control the degree of redundancy of each program based on its evolving playback demand, ensuring high-quality playback by providing sufficient bandwidth for popular programs. Finally, we introduce a contribution-based incentive policy that encourages PVRs to actively participate by contributing resources, while discouraging excessive consumption of the combined storage pool. Through extensive experiments, we demonstrate the effectiveness of our proposed collaborative TV program recording system in terms of storage efficiency and performance. 展开更多

This paper presents the design of a low-power multi-channel analog front-end(AFE) for bio-potential recording. By using time division multiplexing(TDM), a successive approximation register analog-to-digital converter(SAR ADC) is shared among all 20 channels. A charge-sharing multiplexer(MUX) is proposed to transmit the output signals from the respective channels to the ADC. By separately pre sampling the output of each channel, the sampling time of each channel is greatly extended and additional active buffers are avoided. The AFE is fabricated in a 65-nm CMOS process, and the whole system consumes 28.2 μW under 1 V supply. Each analog acquisition channel consumes 1.25 μW and occupies a chip area of 0.14 mm2. Measurement results show that the AFE achieves an input referred noise of 1.8 μV·rms in a 350 Hz bandwidth and a noise efficiency factor(NEF) of 4.1. The 12-bit SAR ADC achieves an ENOB of 9.8 bit operating at 25 k S/s. The AFE is experimented on real-world applications by measuring human ECG and a clear ECG waveform is captured. 展开更多

Anthropogenic climate change is altering species distributions globally.While species distributions are expected to shift to higher latitudes and elevations under global warming,empirical evidence on distribution shifts is mixed,and factors mediating the direction and magnitude of range shifts remain unclear.Using a dataset of 132new provincial records for 96 resident bird species from 2000 to 2023,we measured geographic distance,latitudinal shift,and temperature shift from each new record to the historical range for each species to test for poleward shifts.We assessed taxonomic variation in the magnitude of range shifts and used phylogenetic generalized linear mixed models to quantify relationships between species traits and the extent of range shifts.Our results revealed that new records occurred at a mean geographic distance of 420 km from historical ranges,with mean latitudinal shifts of+1.68°(poleward)and temperature shifts of-1.33℃(toward colder climates).The magnitude of geographic range shifts was strongly constrained by phylogenetic relatedness.Habitat breadth,habitat openness,and centroid latitude of historical ranges emerged as significant predictors of range shifts.Our results suggest that resident bird species'geographic ranges in China are shifting poleward,but the magnitude of these shifts is non-random across lineages.Species with broader habitat preferences and those from warmer climates are more likely to shift farther from their historical ranges and toward higher latitudes.This study emphasizes taxonomic variation in species range shifts and highlights the need for species-and site-specific conservation strategies under global warming. 展开更多

BACKGROUND The neurological and psychiatric sequelae of coronavirus disease 2019(COVID-19)have been documented,yet further data are needed to thoroughly evaluate the impact of COVID-19 on brain health years after the infection.AIM To examine whether COVID-19 infection is associated with exacerbation,recurrence,or progression of pre-existing neurological or psychiatric disorders-a highrisk population that is underrepresented in COVID-19 outcome research in National Guard Health Affair patients in 4-years following a COVID-19 diagnosis.METHODS For this multicenter retrospective cohort study,we used data from the National Guard hospitals electronic health records network(BestCare)with over 10 million patients.Our cohort comprised patients who had a COVID-19 diagnosis;a matched control cohort included patient did not expose to COVID-19 in same period.Age and sex were matching factors.We estimated the incidence of 14 neurological and psychiatric outcomes in nearly 4 years after a confirmed diagnosis of COVID-19.Using a multiple logistic regression,we compared incidences with those in propensity score-matched cohorts of patients with no exposure to COVID-19.Ramadan M et al.Neurological and psychiatric risks post-COVID-19 RESULTS Our primary cohort comprised 4437 patients diagnosed with COVID-19,and our propensity-score 1:1 matched control cohort comprised 4437 individuals.Nearly two-third of the COVID-19 cohort(71%)were diagnosed in 2020,and 2021.The most prevalent diagnoses for both cohorts were epilepsy 30.68%,mood disorder 23.92%,and nerve plexus disorder 22.13%.Dementia was nearly 4 times higher among COVID-19 cohort(8.27%)compared to the control cohort(2.57%).Five neurological and psychiatric outcomes had odds ratios(OR)that were significantly higher than 1 for people who had COVID-19 compared to people who had never been infected.These outcomes were cognitive deficit OR=1.54,95%confidence interval(CI):1.23-1.91,P=0.0001;nerve plexus disorder OR=1.13,95%CI:1.01-1.25,P=0.02;substance use disorder OR=1.95,95%CI:1.12-3.38,P=0.01;mood disorder OR=1.16,95%CI:1.05-1.29,P=0.003;and anxiety disorder OR=1.39,95%CI:1.07-1.79,P=0.01.CONCLUSION The study highlights the persistent risk of neurological and psychiatric conditions in COVID-19 survivors up to four years post-infection.Although the incidence was lower than in previous large studies,long-term consequences remain significant,emphasizing the need for ongoing monitoring and support in mental health and neurological care. 展开更多

Objectives:Electronic health records(EHRs)offer valuable real-world data(RWD)for Chinese medicine research.However,significant methodological challenges remain in developing integrative Chinese-Western medicine(ICWM)databases.This study aims to establish a best-practice methodological framework,referred to as BRIDGE,to guide the construction of ICWM databases using EHRs.Methods:We developed the methodological framework through a comprehensive process,including systematic literature review,synthesis of empirical experiences,thematic expert discussions,and consultation with an external panel to reach consensus.Results:The BRIDGE framework outlines 6 core components for ICWM-EHR database development:Overall design,database architecture,data extraction and linkage,data governance,data verification,and data quality evaluation.Key data elements include variables related to study population,treatment or exposure,outcomes,and confounders.These databases support various research applications,particularly in evaluating the effectiveness and safety of integrative therapies.To demonstrate its practical value,we developed an ICWM-EHR database on women’s reproductive lifespan,encompassing 2,064,482 patients.This database captures women’s health conditions across the life course,from reproductive age to older adulthood.Conclusions:The BRIDGE methodological framework provides a standardized approach to building high-quality ICWM-EHR databases.It offers a unique opportunity to strengthen the methodological rigor and real-world relevance of Chinese medicine research in integrated healthcare settings. 展开更多
