Search Personalization in Folksonomy by Exploiting Multiple and Temporal Aspects of User Profiles

Social tagging data, also known as folksonomy, are a valuable indication for the user's understanding of a resource. The nature of folksonomy data in which a user annotates a resource with their opinions provides immense potential to contribute to search personalization. The challenge lies in extracting interests from the folksonomy data and building accurate user profiles while maintaining their characteristics. Furthermore, the current state-of-the-art technologies that utilize folksonomy for search personalization have not fully exploited both multiple and temporal aspects in user profiles. In this paper, we propose a search personalization framework that constructs a user profile network with identification of the multiple topics of the user and the temporal values of tags. Then, the user profile network is further explored through a link analysis technique for the network to score the tags by their importance. The performance of the proposed framework is evaluated against various state-of-the-art folksonomy-based personalization models and it consistently outperforms all of the compared models under the conditions of the best combination of ranking functions and link analysis techniques.
A review on global status of fresh and saline groundwater discharge into the ocean

Submarine groundwater discharge (SGD) is the groundwater flow from land to the sea across the seabed, and it includes both terrane freshwater and recirculated seawater in the sub-surface. This review (i) systematically evaluates findings of various quantification methodologies, (ii) examines the estimated SGD in scientific publications between 2000 and 2020, and (iii) quantitatively evaluates current situation of coastal zone management through the bibliometric analysis of research papers. Apart from enhancing the shortage of groundwater resources in coastal area, the SGD brings nutrients (nitrate and phosphate), toxic heavy metals, and organic compounds, and thus contaminate the seawater. Therefore, the improved understanding about location and quantity of global SGD is essential to conserve the coastal and ocean ecosystems.
Phase II study of HCVIDD/MA in patients with newly diagnosed peripheral T-cell lymphoma

A phase II study was performed to evaluate the efficacy of hyper-fractionated cyclophosphamide, vincristine, pegylated liposomal doxorubicin and dexamethasone alternating with methotrexate/cytarabine (HCVIDD/MA) in patients with newly diagnosed peripheral T-cell lymphoma (PTCL), excluding ALK-positive anaplastic large cell lymphoma. Fifty-three patients were enrolled. Treatment was planned for up to 8 cycles but only 9% of patients received more than 6 cycles due primarily to disease progression (n = 13) or prolonged thrombocytopenia (n = 12). The overall response rate was 66% with a complete response rate of 57%. Median progression-free survival (PFS) was 7·5 months. With a median follow-up of 7·6 years, 5-year PFS and overall survival (OS) were 21% and 48%, respectively. The patients with extranodal Natural Killer-cell lymphoma had a shorter PFS (median, 2·4 months) than other subtypes. Grade 3/4 anaemia, neutropenia and thrombocytopenia were observed in 66%, 74% and 79% of patients, respectively. Of note, 23% of patients discontinued therapy due to prolonged thrombocytopenia. In conclusion, HCVIDD/MA for the first-line treatment of PTCL patients is associated with significant myelosuppression leading to poor treatment adherence, and the response and survival outcomes with this regimen are similar to standard CHOP. This study was registered at www.clinicaltrials.gov as #NCT00290433.
Spectral diversity of photosystem I from flowering plants

Photosystem I and II (PSI and PSII) work together to convert solar energy into chemical energy. Whilst a lot of research has been done to unravel variability of PSII fluorescence in response to biotic and abiotic factors, the contribution of PSI to in vivo fluorescence measurements has often been neglected or considered to be constant. Furthermore, little is known about how the absorption and emission properties of PSI from different plant species differ. In this study, we have isolated PSI from five plant species and compared their characteristics using a combination of optical and biochemical techniques. Differences have been identified in the fluorescence emission spectra and at the protein level, whereas the absorption spectra were virtually the same in all cases. In addition, the emission spectrum of PSI depends on temperature over a physiologically relevant range from 280 to 298 K. Combined, our data show a critical comparison of the absorption and emission properties of PSI from various plant species.
The Role of School Connectedness and Friend Contact in Adolescent Loneliness, and Implications for Physical Health

The current study investigated how adolescents' loneliness relates to school connectedness, classmate support, teacher support, and offline and online communication with friends. We also examined the association between loneliness, physical health, and sleep. Data came from the Scottish Health Behavior in School-aged Children (HBSC). The total sample was 2983 adolescents (F = 1479 [49.6%]) aged 14-17 years (M = 15.66, SD = 0.39) from 117 secondary schools in Scotland. Results showed that (1) higher teacher support, classmate support, and offline contact with friends predicted lower levels of loneliness, (2) online friendship engagement predicted higher levels of loneliness, and (3) poor health and sleep were positively associated with loneliness. The study offers new findings, highlighting the role played by classmates/peers and teachers in reducing loneliness. Supporting previous research, we also found associations between loneliness, poor sleep, and worse physical health.
A Skip Attention Mechanism for Monaural Singing Voice Separation

This work proposes a simple but effective attention mechanism, namely Skip Attention (SA), for monaural singing voice separation (MSVS). First, the SA, embedded in the convolutional encoder-decoder network (CEDN), realizes an attention-driven and dependency modeling for the repetitive structures of the music source. Second, the SA, replacing the popular skip connection in the CEDN, effectively controls the flow of the low-level (vocal and musical) features to the output and improves the feature sensitivity and accuracy forMSVS. Finally, we implement the proposed SA on the Stacked Hourglass Network (SHN), namely Skip Attention SHN (SA-SHN). Quantitative and qualitative evaluation results have shown that the proposed SA-SHN achieves significant performance improvement on the MIR-1K dataset (compared to the state-of-the-art SHN) and competitive MSVS performance on the DSD100 dataset (compared to the state-of-the-art DenseNet), even without using any data augmentation methods.
[Complex posttraumatic stress disorder in adults]

The term "complex posttraumatic stress disorder" (cPTSD) appeared in the scientific literature 30 years ago and has now been included in a diagnostic catalogue for the first time, namely in the International Statistical Classification of Diseases and Related Health Problems 11 (ICD-11) which was officially published at the beginning of 2022. This usually severely debilitating disorder often poses great challenges to treating physicians and psychotherapists in everyday clinical practice. Due to the much-debated overlap of cPTSD with borderline personality disorder (BPD), which is very high in cases of comorbidity of BPD and PTSD, cPTSD became embroiled in scientific discussions about the raison d'être of BPD in the new dimensional concept of personality disorders (PD) in the ICD-11. In addition to a detailed explanation of the diagnostic criteria of cPTSD and their differentiation from other mental disorders, particularly from PTSD, BPD and dissociative disorders, this article summarizes the historical development of the concept of cPTSD to date and the currently available treatment options. The same criteria apply to cPTSD in childhood and adolescence as in adulthood, but there are some special features that are not addressed in this article.
Processing technology for the objects of mobile art in the Upper Paleolithic of Siberia (the Malta site)

Investigation of the technological aspects of the processing of the Siberian collection of animal materials opens up new possibilities for the historical and cultural reconstructions of archaeological materials. The complete collection of processed ivory reflecting technological cycles is shown in single sites of the Classical stage of the Upper Paleolithic in Siberia (Malta, Ust-Cova, Afontova Gora, Listvenka, and Jansky). Materials of animal origin from the collection of Malta (especially ivory) are suitable for their preservation for microscopic analysis. The Malta-site is the main archaeological site of the Upper Paleolithic in Siberia (dated near 19,000-23,000 years BP). The collection is represented by the more than 650 decorated objects of ivory, antler, and bone. A detailed study of the most part of the collection stored in the State Hermitage Museum (St. Petersburg) has established the general steps of processing the ivory, antler, and bone articles at the time of Siberian's Upper Paleolithic. Mobile art of Malta is well known in the scientific and popular press, but our study differs from other studies. The work is based on a set of morphological data, technical, use wear analyzes and experiment. The collection includes the sculptures of people, birds, fish, and animals as well as ornamented plates, rods, and personal ornaments. The microscopic analysis allows one to systematize the process of shape formation, the processing, and the ornamentation of Paleolithic sculptures and personal ornamentations of Malta. In addition, we propose certain stable sets of tools and techniques used to work with each of the selected morphological types of Paleolithic sculpture. We have identified all steps of manufacturing the mobile art pieces including flaking, drilling, carving, grinding, and polishing. A number of tools were employed for the manufacture of artifacts: hammer stones, retouches, bow-shaped drills, perforators, boring, different kinds of burins and knives, reamers, engravers, grinding tablets, and scrapers. The basic tools that were involved in forming shape were planer knives and some variants of scrapers. Burins and knives were employed to make decorative elements. According our opinion, In Malta's tool kit were: the bow-shaped drills, perforators, and burins, as well as different kind of burins were used for drilling the holes and forming of the ornamental elements. The different types of abrasives were also used. (C) 2015 Elsevier Ltd and INQUA. All rights reserved.
Warming of surface water in the large and shallow lakes across the Yangtze River Basin, China, and its driver analysis

A variety of physical, chemical, and biological processes within the lakes relies on the surface water temperature while the spatial pattern of large lakes of different warming trends and their connections with climate change remain unclear. Using correlation analysis, regression tree analysis (RTA), and general linear models (GLMs), we have estimated the warming trends of 192 lakes since 2000 in the populated Yangtze River Basin, China, to identify dominant climate drivers and quantify their contributions. The results show that surface water temperature has increased substantially in the majority of the investigated lakes (179 from a total of 192 lakes) at a rate of 0.29 (- 0.12 to 0.62) °C/decade (median and 95% confidence interval). The shallower lakes (< 13.1 m in depth) usually have the faster median warming rates than the deeper lakes (i.e., 0.37 °C/decade versus 0.16 °C/decade). We find that in the shallow lakes, rising air temperatures and declining wind speeds can explain the majority of variation in surface water temperature (i.e., 31.4‒80.3% and 13.0‒21.0%, respectively). In contrast, in deeper lakes, change of air temperatures plays a dominant role in water warming (75.4‒91.2%). This study has emphasized the importance of declining wind speed in water warming in large and shallow lakes and illustrated a difference of dominant climatic drivers in water warming between the shallow and deep lakes.
A highly sensitive, easy-and-rapidly-fabricable microfluidic electrochemical cell with an enhanced three-dimensional electric field

An NP-μFEC is a reusable, novel microfluidic electrochemical cell with multiple non-planar interdigitated microelectrode arrays, minimal sample volume, and enhanced electric field penetration for highly sensitive electrochemical analysis. (i) The NP-μFEC features spatial 3-electrode architecture, and a small sample volume (∼4 μL). (ii) Here, [Fe(CN)6]3-/4- redox couple are used as an electrochemical reporter. The effects on the electrochemical properties of NP-μFEC due to the change in the reference electrode (RE) and counter electrode (CE)'s position with respect to the working electrode (WE) position are analyzed. For NP-μFEC, the position of the RE with respect to the WE does not affect the CV, DPV electrochemical profiles. However, the spacing between the CE and WE plays a significant role. (iii) The enhanced three-dimensional electric field penetration in NP-μFEC is validated by finite element analysis simulation using COMSOL Multiphysics. (iv) Without electrode surface modifications, NP-μFEC shows a detection limit (DL) of ∼2.54 × 10-6 M for aqueous [Fe(CN)6]3-/4- probe. (v) The DL for Cu2+, Fe3+, and Hg2+ are 30.5±9.5 μg L-1, 181±58.5 μg L-1, and 12.4±1.95 μg L-1, respectively, which meets the US Environmental Protection Agency (EPA)'s water contamination level for Cu, Fe, and is close to that for Hg (EPA limits are 1300 μg L-1, 300 μg L-1, and 2 μg L-1, respectively). (vi) Further, using a pressure-sensitive adhesive layer to form the channel and create the NP-μFEC configuration simplifies the manufacturing process, making it cost-effective and allowing for rapid adoption in any research lab. NP-μFEC is used to detect heavy metal ions in water. This demonstrates that cost-effective, easy-to-fabricate NP-μFEC can be a new sensitive electrochemical platform.
Adaptive Random Testing for Multiagent Path Finding Systems

The multiagent path finding (MAPF) problem identifies the scheduling of multiple agents simultaneously, such that all of them can reach their targets efficiently. To date, MAPF systems have been assigned important tasks such as traffics and warehouses. It is essential to conduct testing for MAPF systems to detect potential failures. Namely, in an MAPF system, a test case is a specific MAPF scenario, including the initial locations of the agents and the environment for these agents to play in. By testing, we intend to find the scenarios (i.e., test cases) whose executions reveal failures. Testing MAPF systems is challenging due to the complexity of its input and the interactions among multiple agents. This article proposes the testing approach based on the adaptive random testing (ART) for MAPF systems. ART aims to generate new test cases far from the already executed ones. Particularly, to calculate the distance between each pair of test cases, we introduce two metrics, the initial density distribution and the destination density distribution, to characterize the distribution of the agents' initial and destination nodes, respectively. Benefit from ART, the diversity of the information generated during testing can be improved. Experimental results show that compared with the random testing, our approach can detect more diverse failure-revealing scenarios.
Making waves: Defining advanced reduction technologies from the perspective of water treatment

Studies related to advanced reduction technologies (ARTs) have grown exponentially since the term was first coined in 2013. Despite recent interests in ARTs, the conditions and requirements for these processes have yet to be defined and clarifed. In comparision to well defined advanced oxidation technologies/processes (AOTs/AOPs) which involve the generation of hydroxyl radical as the common characteristic, ARTs function by electron donation from a variety of reducing agents and activators. Based on an extensive literature review, we propose that ARTs be defined as processes employing strong chemical reductants with E degrees <= - 2.3 V vs. normal hydrogen electrode at 25 degrees C. While extensive studies have revealed critical fundamental details of AOTs/AOPs mediated processes, there are still significant gaps in elucidation of the mechanistic details of reductive degradation/ transformation of highly toxic compounds by ARTs. A significant number of pollutants and toxins resistant to AOTs/AOPs treatment are effectively degraded by ARTs. A great leap is needed on understanding ARTs to fully utilize their potential to efficiently remediate recalcitrant compounds of different sources and structures.
Mutation of the TP53 gene in acute lymphoblastic leukemia does not affect survival outcomes after haploidentical hematopoietic stem cell transplantation

Previous studies have demonstrated that TP53 mutation is correlated with insufficient therapy response and unfavorable prognosis in acute lymphoblastic leukemia (ALL). Few studies have investigated the impact of TP53 mutation in ALL patients after haploidentical hematopoietic stem cell transplantation (haplo-HSCT). We completed a retrospective study of 65 ALL patients with available TP53 status who underwent haplo-HSCT. They were divided into a TP53 mutation group (TP53mut ) and a TP53 wild-type (TP53wt ) group. TP53mut showed comparable 2-year cumulative incidence of relapse (CIR) rates (13.1% vs 12.5%, P = .96) and 2-year leukemia-free survival (LFS) (74.2% vs 77.4%, P = .80) with TP53wt . No significant differences in 2-year overall survival (OS) rates (82.9% vs 87.3%, P = .61) or 2-year NRM rates (12.7% vs 10.2%, P = .69) were observed in TP53mut and TP53wt patients. Multivariate analysis suggested that white blood cell (WBC) count at initial diagnosis (>50 × 109 /L: hazard ratio [HR] = 3.860, P = .016) and age (>40 years old: HR = 4.120, P = .012) are independent risk factors for 2-year LFS. Our study showed that TP53 mutations may not be related to the unfavorable impact on survival in ALL patients after treatment with haplo-HSCT. The present results suggested that haplo-HSCT may eliminate the poor prognosis effect of TP53 mutation in ALL.
Probabilistic intuitionistic fuzzy c-means algorithm with spatial constraint for human brain MRI segmentation

Segmentation of brain MRI images becomes a challenging task due to spatially distributed noise and uncertainty present between boundaries of soft tissues. In this work, we have presented intuitionistic fuzzy set theory based probabilistic intuitionistic fuzzy c-means with spatial neighborhood information method for MRI image segmentation. We have investigated two well known negation functions namely, Sugeno's negation function and Yager's negation function for representing the image in terms of intuitionistic fuzzy sets. The proposed approach takes leverage of intuitionistic fuzzy set theory to address vagueness and uncertainty present in the data. The spatial neighborhood information term in the segmentation process is included to dampen the effect of noise. The segmentation performance of the proposed method is evaluated in terms of average segmentation accuracy and Dice score. Further, the comparison of the proposed method with other similar state-of-art methods is carried out on two publicly available brain MRI dataset which shows the significant improvements in segmentation performance in terms of average segmentation accuracy and Dice score. The proposed approach achieves on average 91% average segmentation accuracy in the presence of noise and intensity inhomogeneity on BrainWeb simulated dataset, which outperformed the state-of-art methods.
A Survey of the Nurse Rostering Solution Methodologies: The State-of-the-Art and Emerging Trends

This paper presents an overview of recent advances for the Nurse Rostering Problem (NRP) based on methodological papers published between 2012 to 2021. It provides a comprehensive review of the latest solution methodologies, particularly computational intelligence (CI) approaches, utilized in benchmark and real-world nurse rostering. The methodologies are systematically categorised (Heuristics, Meta-heuristics, Hyper-heuristics, Mathematical Optimisation, Matheuristics and Hybrid Approaches). The NRP benchmark repositories and the respective state-of-the-art methods are also presented. A distinctive feature of this survey is its focus on the emerging trends in terms of solution methodologies and benchmark datasets. Meta-heuristics are the most popular choices in addressing NRP. Matheuristics, one of most popular methodologies in addressing the NRP, has been an emerging trend in recent years (2018 onwards). The INRC-I dataset is the most popular benchmark currently in use by researchers to test their algorithms. An in-depth discussion on the challenges and research opportunities is provided. The summary and analysis of the recently published NRP methodological papers in this survey is valuable for the CI and Operational Research (OR) communities especially early career researchers seeking to find gaps and identify emerging trends in this fast-developing, important research area.
Unravelling the landscape of skin cancer through single-cell transcriptomics

The human skin is a complex organ that forms the first line of defense against pathogens and external injury. It is composed of a wide variety of cells that work together to maintain homeostasis and prevent disease, such as skin cancer. The exponentially rising incidence of skin malignancies poses a growing public health challenge, particularly when the disease course is complicated by metastasis and therapeutic resistance. Recent advances in single-cell transcriptomics have provided a high-resolution view of gene expression heterogeneity that can be applied to skin cancers to define cell types and states, understand disease evolution, and develop new therapeutic concepts. This approach has been particularly valuable in characterizing the contribution of immune cells in skin cancer, an area of great clinical importance given the increasing use of immunotherapy in this setting. In this review, we highlight recent skin cancer studies utilizing bulk RNA sequencing, introduce various single-cell transcriptomics approaches, and summarize key findings obtained by applying single-cell transcriptomics to skin cancer.
Gender and race/ethnicity differences in occupational activity among students

Occupational physical activity (OPA) is related to positive health outcomes and meeting overall physical activity recommendations. OPA participation typically varies across racial/ethnic groups and by gender, though little research has examined differences in OPA among college students. A cross-sectional, online survey of college students examined demographics and OPA. Participants (n = 3739) were predominately Non-Hispanic White (77.1%) and female (57.8%) aged 20.97 ± 1.52. Employed students reported greater total PA compared with non-employed students. Males reported significantly greater vigorous OPA, overall OPA, and total PA compared with females. Among employed students, OPA contributed significantly to overall PA levels. Males reported significantly greater OPA compared with females and there were several significant differences by race/ethnicity. Academic performance was related to OPA. These findings provide some insight on the OPA levels of a population group that has not been thoroughly examined.
