A Cooperative Caching Scheme for VCCN With Mobility Prediction and Consistent Hashing

In order to mitigate the performance degradation of intermittent vehicular network caused by traffic mobility and sporadic connectivity issues, Vehicular Content Centric Network (VCCN) has been proposed to apply many technologies in Content Centric Network (CCN) into vehicular ad hoc networks. The open in-network caching strategy of CCN enables sharing and coordination of the cached data among multiple nodes as an efficient data access without relying on remote fetching. Nonetheless, few studies have considered the effective use of overall cache capacity with these cooperative nodes, especially the issues of cache duplication. Furthermore, most content replacement polices have ignored the needs of cooperative contents when making cache decisions. In this paper, we design a novel Cooperative Caching scheme by using Mobility Prediction and Consistent Hash for VCCN (called CCMPCH). Specifically, based on the observation that vehicles with the same trajectory are more likely to maintain stable communication links, we adopt Prediction by Partial Matching (PPM) to forecast each vehicle’s path and cluster the vehicles with similar future path, moving direction, and moving speed into one group. In each cluster, the consistent hash algorithm is used to allocate contents among cooperative nodes, thereby reducing unnecessary cache duplication while maintaining strong content availability. A popularity-based cache replacement policy is also developed to prioritize cooperative contents. We evaluate CCMPCH via extensive simulations, which demonstrates its higher cache hit ratio, shorter content access delay, and lower hop count compared to other state-of-the-art schemes.
Multi-scale integrative analyses identify THBS2+ cancer-associated fibroblasts as a key orchestrator promoting aggressiveness in early-stage lung adenocarcinoma

Rationale: Subsets of patients with early-stage lung adenocarcinoma (LUAD) have a poor post-surgical course after curative surgery. However, biomarkers stratifying this high-risk subset and molecular underpinnings underlying the aggressive phenotype remain unclear. Methods: We integrated bulk and single-cell transcriptomics, proteomics, secretome and spatial profiling of clinical early-stage LUAD samples to identify molecular underpinnings that promote the aggressive phenotype. Results: We identified and validated THBS2, at multi-omic levels, as a tumor size-independent biomarker that robustly predicted post-surgical survival in multiple independent clinical cohorts of early-stage LUAD. Furthermore, scRNA-seq data revealed that THBS2 is exclusively derived from a specific cancer-associated fibroblast (CAF) subset that is distinct from CAFs defined by classical markers. Interestingly, our data demonstrated that THBS2 was preferentially secreted via exosomes in early-stage LUAD tumors with high aggressiveness, and its levels in the peripheral plasma associated with short recurrence-free survival. Further characterization showed that THBS2-high early-stage LUAD was characterized by suppressed antitumor immunity. Specifically, beyond tumor cells, THBS2+ CAFs mainly interact with B and CD8+ T lymphocytes as well as macrophages within tumor microenvironment of early-stage LUAD, and THBS2-high LUAD was associated with decreased immune cell infiltrates but increased immune exhaustion marker. Clinically, high THBS2 expression predicted poor response to immunotherapies and short post-treatment survival of patients. Finally, THBS2 recombinant protein suppressed ex vivo T cells proliferation and promoted in vivo LUAD tumor growth and distant micro-metastasis. Conclusions: Our multi-level analyses uncovered tumor-specific THBS2+ CAFs as a key orchestrator promoting aggressiveness in early-stage LUAD.
Success Management and the Project Management Body of Success Management and the Project Management Body of Knowledge (PMBOK): An Integrated Perspective Knowledge (PMBOK): An Integrated Perspective

It is a significant challenge to define and achieve success in information systems project management, given the high number and diversity of involved stakeholders and variables that need to be taken into account by project managers and their teams. Project management standards and guides are valuable in this context, as they provide concepts, processes and techniques related to several complementary knowledge areas (e.g., cost, quality, risk, etc.). However, they do not explicitly define what needs to be done towards managing the success of a project (including, for instance, the formal evaluation of success). To address this gap, we propose a new model for the integration of the success management activities into the Project Management Body of Knowledge (PMBOK) guide. To this end, a Design Science Research process has been adopted. The research is in progress and the resulting model is currently being evaluated in information systems projects.
Coastal River Response to Transgression: A New Look at the Trinity Incised Valley Using Multi-Resolution Seismic Imaging

Modern lowland river systems show transitions in flow characteristics near coastlines that lead to systematic changes in sediment deposition and stratigraphic architecture. Sensitivity of fluvial morphodynamics to base-level has important implications for the prediction and interpretation of fluvial stratigraphy, particularly in deposits formed during periods of relative sealevel rise such as the early Holocene. Improving our understanding of how fluvial stratigraphy is created and preserved in such environments is crucial to paleoenvironmental reconstruction, sand resource estimation, and mapping subsurface facies distributions. A significant challenge has been capturing the spatiotemporal evolution of such systems on long timescales (centuries to millennia), often due to poor data coverage and resolution. Here we investigate the offshore stratigraphic architecture of the Trinity coastal river system, Texas. The paleo-valley is interpreted to have formed during the last lowstand and filled by backstepping fluvial-deltaic and estuarine sediments
Analysis of Treatment Outcomes of Infertile Japanese Women Based on Serum Anti-Müllerian Hormone Levels to Investigate Its Criteria in Infertile Practice

We analyzed the clinical data of infertility treatment performed with reference to serum anti-Müllerian hormone (AMH) levels. Through this analysis, we studied the clinical criteria of serum AMH levels as a treatment strategy. From 2014 to 2018, 495 infertile patients were enrolled in the present study, and clinical data were collected until the end of 2020. Patients were divided into three groups according to serum AMH levels: group A (n=123), a low group (AMH<1.35 ng/mL); group B (n=248), a middle group (1.35 ≤ AMH<5.19 ng/mL); and group C (n=124), a high group (AMH ≥ 5.19 ng/mL). The patient characteristics, results of infertility therapy, and obstetric outcomes were compared among the groups. Age was significantly different among the three groups. The pregnancy rate was lowest in group A, where pregnant patients were younger and had higher AMH levels. The cumulative birth rates were higher in younger women in groups A and B; however, the rates did not differ regarding serum AMH levels in both groups. Age did not affect the cumulative birth rates in group C. There was no relationship between serum AMH levels and the occurrence of complications during pregnancy. The present study was of value in examining the criteria of serum AMH levels in determining the treatment plan in Japanese fertility practice.
Accelerating ILL-Conditioned Robust Low-Rank Tensor Regression

An important problem that arises across different applications in signal processing, machine learning, and data science is to reliably estimate a tensor from a small number of measurements that are possibly corrupted. Leveraging the low-rank structure under the Tucker decomposition, we propose a provably efficient algorithm that directly estimates the tensor factors by solving a nonsmooth and nonconvex composite optimization problem that minimizes the least absolute deviation loss. The proposed algorithm—built on subgradient methods—harnesses preconditioners that are designed to be equivariant w.r. t. the low-rank parameterization, and is shown to achieve local linear convergence at a constant rate under the Gaussian design. Numerical experiments are provided to corroborate the superior performance of the proposed algorithm.
Assessing void in Grade-A office buildings in Lagos metropolis

The evidence of void in the most categorized office buildings, Grade-A Office Buildings, spurred this research. It was conceived that such office buildings that are built with every form of specifications should be the choice of occupants and as such should not experience any void. This study thereby aimed at discovering factors that lead to such void, proportion of void experienced and the average rent loss and period of void as a result of the lull in the property market for such class of property. The research being a survey entailed the distribution of questionnaires to the property managers of the twelve identified Grade-A Office Buildings in the study area. Data gotten were analysed using descriptive and inferential statistics through the use of Statistical Package for the Social Sciences (SPSS) Version 25. Subsequent discussions were made in line with proffered suggestion with a view to eradicating or at least reducing the void so as to enhance the investment outcome.
Phytochemical constituents and proximate analysis of dry pineapple peels

The pineapple and its skin contain a lot of vitamin C, which helps to prevent and fight illnesses. Dry pineapple peel phytochemicals and proximate analysis were investigated in this study. Oil derived from ripe pineapple peels was tested for phytochemical constituents and proximate analysis of dry peel pineapple using a conventional method.Moisture content was 5.10±0.07%, the ash content was 3.78±0.05%, the fat content was 5.57±0.08%, the protein content was 5.78±0.10%, the crude fiber content was 4.10±0.06%, and the carbohydrate content was 75.68±0.86%. Alkaloid phenol, tannin, flavonoid, and saponin were identified as phytochemical components from the result of phytochemical screening.The presence of secondary metabolites in pineapple peel oil is a positive indicator that if thoroughly investigated, bioactive chemicals with significant biological activity may be extracted. As a result, it's plausible to believe that nutraceutical advantages can be derived from this waste (pineapple peel), potentially boosting humanity's prosperity, health and well-being.
Building production management competencies for building students: academia and construction industry perspectives

The study examined the competencies required by building students for building production management and the barriers to their competency in the practice of building production management in the construction industry. Using a quantitative research method, a total of 302 construction professionals and 35 building programme lecturers completed a set of questionnaires survey. The data were analyzed using descriptive and inferential statistical tools such as mean score and Mann Whitney test. Study findings identified setting out of different building types, interpretation of architectural drawings and specifications, tendering and contract processes, and construction of various components and effective communication on construction sites as the most significant competencies for building production management practice in the construction industry. However, the study discovered a significant difference in the competencies for building production management practice between construction professionals and building lecturers. Also, the study identified poor institutional and industry collaboration, underfunding of institutions, insufficient equipment and infrastructure for training, and theoretical training rather than practical training as the major barriers to the competency of building production management practice in the construction industry. The study suggested a more vital collaboration between the construction industry with tertiary institutions in needs assessment, funding, provision of infrastructures and involvement in the practical training of students
Leapfrog migration and residents: New migratory habits in Swedish Greylag geese

Abstract Knowledge about intraspecific and individual variation in bird migration behavior is important to predict spatiotemporal distribution, patterns of phenology, breeding success, and interactions with the surrounding environment (e.g., human livelihoods). Such variation is key to adaptive, evolutionary responses, i.e., how individuals respond spatiotemporally to the environment to maximize fitness. In this study we used GPS location data from one to three full annual cycles from 76 Greylag geese (Anser anser) to test the hypothesis that geese originating at five latitudinally separated capture sites in Sweden have different migration strategies. We also assessed individual consistency in movement strategy over consecutive annual cycles. We used the scale‐independent net squared displacement modeling framework to quantify variables of autumn and spring migration for geese from each capture site: distance, timing, and duration. Our results demonstrate a positive correlation between migration distance and latitudinal origin. Geese from the northernmost site on average migrated farther south and about 15 times as far as the short‐moving or resident geese from the two southernmost sites. Movement strategies of individual geese varied considerably both within and among capture sites. Individual consistency in movement strategy from one annual cycle to the consecutive was high in geese from the northern sites moving the farthest, whereas the resident or short‐moving geese from the southernmost sites generally showed lower or no individual consistency. These changes have come about during a time span so short (i.e., ca. 35 years or 8–10 generations) that it can unlikely be explained by classical Darwinian between‐generation adaptation. Consequently, and given that young geese follow their parents during their first migration, we presume an important role of within‐family, inter‐generation change as a driver behind the large‐scale changed migration habits in Swedish Greylag geese.
BNT162b2 and ChAdOx1 nCoV-19 vaccinations, incidence of SARS-CoV-2 infections and COVID-19 hospitalisations in Scotland in the Delta era

Background The emergence of the B.1. 617.2 Delta variant of concern was associated with increasing numbers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and COVID-19 hospital admissions. We aim to study national population level SARS-CoV-2 infections and COVID-19 associated hospitalisations by vaccination status to provide insight into the association of vaccination on temporal trends during the time in which the SARS-CoV-2 Delta variant became dominant in Scotland. Methods We used the Scotland-wide Early Pandemic Evaluation and Enhanced Surveillance (EAVE II) platform, covering the period when Delta was pervasive (May 01 to October 23, 2021). We performed a cohort analysis of every vaccine-eligible individual aged 20 or over from across Scotland. We determined the vaccination coverage, SARS-CoV-2 incidence rate and COVID-19 associated hospitalisations incidence rate. We then stratified those rates by age group, vaccination status (defined as “unvaccinated”, “partially vaccinated” (1 dose), or “fully vaccinated” (2 doses)), vaccine type (BNT162b2 or ChAdOx1 nCoV-19), and coexisting conditions known to be associated with severe COVID-19 outcomes. Results During the follow-up of 4 183 022 individuals, there were 407 405 SARS-CoV-2 positive cases with 10 441 (2.6%) associated with a hospital admission. Those vaccinated with two doses (defined as fully vaccinated in the current study) of either vaccine had lower incidence rates of SARS-CoV-2 infections and much lower incidence rates of COVID-19 associated hospitalisations than those unvaccinated in the Delta era in Scotland. Younger age groups were substantially more likely to get infected. In contrast, older age groups were much more likely to be hospitalised. The incidence rates stratified by coexisting conditions were broadly comparable with the overall age group patterns. Conclusions This study suggests that national population level vaccination was associated with a reduction in SARS-CoV-2 infections and COVID-19 associated hospitalisation in Scotland throughout the Delta era.
Impact of smoking status and chronic obstructive pulmonary disease on pulmonary complications post lung cancer surgery

Introduction Smoking and chronic obstructive pulmonary disease (COPD) are associated with an increased risk of post-operative pulmonary complications (PPCs) following lung cancer resection. It remains unclear whether smoking cessation reduces this risk. Methods Retrospective review of a large, prospectively collected database of over 1000 consecutive resections for lung cancer in a quaternary lung cancer centre over a 23-year period. Results One thousand and thirteen patients underwent curative-intent lobectomy or pneumonectomy between 1995 and 2018. Three hundred and sixty-two patients (36%) were ex-smokers, 314 (31%) were current smokers and 111 (11%) were never smokers. A pre-operative diagnosis of COPD was present in 57% of current smokers, 57% of ex-smokers and 20% of never smokers. Just over 25% of patients experienced a PPC. PPCs were more frequent in current smokers compared to never smokers (27% vs 17%, p = 0.036), however, no difference was seen between current and ex-smokers (p = 0.412) or between never and ex-smokers (p = 0.113). Those with a diagnosis of COPD, independent of smoking status, had a higher frequency of both PPCs (65% vs 35%, p<0.01) and overall complications (60% vs 40%, p<0.01) as well as a longer length of hospital stay (10 vs 9 days, p<0.01). Conclusion Smoking and COPD are both associated with a higher rate of PPCs post lung cancer resection. COPD, independent of smoking status, is also associated with an increased overall post-operative complication rate and length of hospital stay. An emphasis on COPD treatment optimisation, rather than smoking cessation in isolation, may help improve post-operative outcomes.
A dual-process approach to prosocial behavior under COVID-19 uncertainty

Uncertainty has been shown to reduce the willingness to cooperate in various social dilemmas and negatively affect prosocial behavior. However, some studies showed that uncertainty does not always decrease prosocial behavior, depending on the type of uncertainty. More specifically, recent research has shown that prosocial behavior tends to increase under impact uncertainty—uncertainty about the consequences for others if they become infected. In addition, researchers have argued that intuition favors prosocial behavior while deliberation leads to selfish behavior. Our study explored how intuitive (time pressure) or deliberate mental processing, under outcome, or impact uncertainty affect prosocial behavior in the context of the COVID-19 pandemic. Our sample consists of 496 participants, and we used a 4 (COVID-19 scenario: Control vs. Impact Uncertainty vs. Worst-Case vs. Indirect Transmission) by 2 (decision time: time delay vs. time pressure) between-subjects design. Results suggest that participants are more inclined to stay at home (prosocial intention) when forced to make their decisions intuitively rather than deliberately. Additionally, we found that uncertainty does not always decrease prosocial behavior. It seems that uncertainty does not affect the prosocial intention in a scenario with a real infectious disease. These findings suggest that the distinction between outcome and impact uncertainty may be due to the realism of experimental stimuli interventions.
levels In situ depletion of phytoplankton by an azooxanthellate soft

-The in situ removal of phytoplankton by the soft coral Dendronephthya hemprichi was investigated by taking small-scale measurements of chlorophyll concentrations around colonies on a reef of the northern Red Sea. The chlorophyll concentration downstream of a 0.75-m-deep colony thicket was depleted by 6.4% (+- 1.4% SE) compared with the water upstream. Neighboring organisms are thus exposed to water that is significantly depleted of phytoplankton. A 0.75 X 0.1 X 0.1-m passage of actively feeding colonies removed 34 mg of carbon per day from the water, equivalent to - 1.3 times their respiratory carbon demand. Rates of algae intake were also estimated by determining the decrease in gut fluo- rescence in starved colonies. The in situ depletion technique showed a three- to sixfold greater sensitivity compared with the gut fluorescence technique, and should be preferred as a technique for estimating feeding rates.

Rapid increase in SARS-CoV-2 seroprevalence during the emergence of Omicron variant, Finland

Objectives The aim of this study was to assess changes in exposure and prevalence of SARS-CoV-2 infection during the first months of emergence of Omicron variant in the Greater Helsinki area, Finland. Methods A prospective seroepidemiological survey of SARS-CoV-2 was conducted on 1,600 serum specimens sent to Helsinki University Hospital Laboratory (HUSLAB) for HIV serology between 15 November 2021 and 6 March 2022 (calendar weeks 46/2021 - 9/2022). For each calendar week, 100 serum specimens were randomly selected and analysed for SARS-CoV-2 IgG antibodies against nucleocapsid (N) and spike 1 (S1) protein with Abbott SARS-CoV-2 IgG (N protein) and SARS-CoV-2 IgG II Quant (S protein) tests, respectively. Results The prevalence of N antibodies increased from 5.2% (weeks 46-50/2021) to 28.2% (weeks 5-9/2022) during the study period. The proportion of seronegative samples as well as anti-N negative, anti-S1 positive samples decreased correspondingly from 11.6% to 3.8%, and 84.2% to 68.2%, respectively. Anti-N positive samples that were anti-S1 negative only began to appear as of week 2/2022. Conclusions A rapid increase in the N antibody prevalence was observed over the study period, suggesting a high transmission rate. A substantial proportion of COVID-19 cases remained undiagnosed during the emergence of Omicron variant in the Greater Helsinki Area, Finland.
