description: Objective:To determine the association between adherence, dose and low-density lipoprotein (LDL) cholesterol response in patients with type 2 diabetes initiating statin treatment.Research design and methods:This cohort study was performed using data for 2007–2012 from the Groningen Initiative to Analyse Type 2 Diabetes Treatment (GIANTT) database. The association between adherence to a standard-dose statin and LDL cholesterol response was assessed using linear regression, adjusting for covariates. The effect of low-dose versus standard-dose was assessed in a propensity-score matched cohort. Adherence rates, defined as the proportion of days covered (PDC), were estimated between statin initiation and LDL outcome measurement.Main outcome measure:LDL cholesterol level at follow-up.Results:The effect of adherence on LDL cholesterol response, measured in 2160 patients, was dependent on the baseline LDL cholesterol level. For patients with a baseline LDL cholesterol of 3.7 mmol/l and an adherence rate of 80%, a 40% reduction in LDL cholesterol was predicted. In the matched sample of 1144 patients, the treatment dose showed a difference in impact on the outcome for adherence rates higher than 50%. It was estimated that a patient with a baseline LDL cholesterol of 3.7 mmol/l will need an adherence rate of at least 76% on low-dose and 63% on standard-dose treatment to reach the LDL cholesterol target of 2.5 mmol/l.Limitations:Adherence was measured as the PDC, which is known to overestimate actual adherence. Also, we were not able to adjust for lifestyle factors.Conclusions:We determined the concurrent effect of treatment adherence and dose on LDL cholesterol outcomes. Given the adherence levels seen in clinical practice, diabetes patients initiating statin treatment are at high risk of not reaching the recommended cholesterol target, especially when they start on a low-dose statin.

description: The asymmetry of line profiles, i.e., the secondary component, is crucial to understanding the energy release of coronal holes (CH), quiet sun (QS), and bright points (BPs). We investigate the asymmetry of Si IV 1393.75 Å of the transition-region (TR) line recorded by Interface Region Imaging Spectrometer (IRIS) and co-spatial-temporal Atmospheric Imaging Assembly (AIA) and Helioseismic and Magnetic Imager (HMI) data onboard Solar Dynamics Observatory (SDO) for three time series on 26 April 2015, 24 July 2014, 26 July 2014. Most asymmetric profiles are in the complex magnetic field regions of the networks. The asymmetric profiles are fitted with both single and double Gaussian models. The mean value of Doppler velocity of the second component is almost zero (with a significant standard deviation) in QS/CH, which may indicate that the physical process to trigger the secondary Gaussian originates at the formation height of Si IV. While the mean Doppler velocity from secondary Gaussian in BPs is around +4.0 km/s (redshifted). The non-thermal velocities of the secondary Gaussian in all three regions are slightly higher than the single Gaussian. The statistical investigation leads to the prevalence of blueshifted secondary components in QS/CH. However, secondary Gaussian in the BPs redshifted, i.e., the BPs redshift behavior could be interpreted due to the site of reconnection located above the formation height of the Si IV line. The peak intensity of the second component for all three regions is likely to follow a power law that is a signature of the small-scale flaring-like trigger mechanism.

description: We propose a feasible scheme to realize a four-band Stiefel-Whitney insultor (SWI) with spin-orbit coupled ultracold atoms in an optical Raman lattice. Four selected spin states are coupled by carefully designed Raman lasers, to generate the desired spin-orbit interactions with spacetime inversion symmetry. We map out a phase diagram with respect to the experimental parameters, where a large topological phase region exists. We further present two distinct detection methods to resolve the non-abelian band topology, in both equilibrium and dynamical ways. The detection relies on the spin textures extracted from the time-of-flight imaging, showing the tomographic signatures in the ground states and long-time averaged patterns on certain submanifold via a bulk-surface duality. Our work paves a realistic way to explore novel real topology with quantum matters.

description: Objective: To provide a differential diagnosis and recommendations for care for an individual with suspected delusional parasitosis secondary to human immunodeficiency virus (HIV). Method: A 62-year-old male with sexually acquired, chronic, and well-managed HIV infection was referred for neuropsychological evaluation and treatment recommendations following extensive self-manipulation of a sternoclavicular cystic mass and superficial skin lesions over most of his body. The patient reported that he had pulled long calcified tendrils out of the mass over a period of several weeks and that “encapsulated fat” was flowing beneath his skin. Results: Numerous lab panels were negative for any acute medical pathology. Clinical neuroimaging was unremarkable. Neuropsychological evaluation revealed a profile consistent with mild neurocognitive disorder due to HIV. Medical and behavioral recommendations were made for the management of delusional thought processes consistent with atypical delusional parasitosis and other symptoms. The patient was responsive to carefully crafted provider feedback and his delusional and somatic symptoms decreased significantly with risperidone. Conclusions: This case illustrates the utility of neuropsychological assessment and provider feedback in the diagnosis and care of HIV-related neurocognitive disorder, the context of a delusional disorder.

description: Objective: To identify approximately 500 cases of incident cognitive impairment (ICI) in a large, national sample adapting an existing cognitive test-based case definition and to examine relationships of vascular risk factors with ICI. Method: Participants were from the REGARDS study, a national sample of 30,239 African-American and White Americans. Participants included in this analysis had normal cognitive screening and no history of stroke at baseline, and at least one follow-up cognitive assessment with a three-test battery (TTB). Regression-based norms were applied to TTB scores to identify cases of ICI. Logistic regression was used to model associations with baseline vascular risk factors. Results: We identified 495 participants with ICI of 17,630 eligible participants. In multivariable modeling, income (OR 1.83 CI 1.27,2.62), stroke belt residence (OR 1.45 CI 1.18,1.78), history of transient ischemic attack (OR 1.90 CI 1.29,2.81), coronary artery disease(OR 1.32 CI 1.02,1.70), diabetes (OR 1.48 CI 1.17,1.87), obesity (OR 1.40 CI 1.05,1.86), and incident stroke (OR 2.73 CI 1.52,4.90) were associated with ICI. Conclusions: We adapted a previously validated cognitive test-based case definition to identify cases of ICI. Many previously identified risk factors were associated with ICI, supporting the criterion-related validity of our definition.

description: In this work, aqueous glycerol solutions are atomized to investigate the influence of the viscosity on the droplet size and the general atomization behavior in a setup using standing surface acoustic waves (sSAW) and a fluid supply at the boundary of the acoustic path. Depending on the fluid viscosity, the produced aerosols have a monomodal or polymodal size distribution. The mean droplet size in the dominant droplet fraction, however, decreases with increasing viscosity. Our results also indicate that the local wavefield conditions are crucial for the atomization process.

description: We present a brief review of literature related to blogs and news sites; our focus is on publications related to COVID-19. We primarily focus on the role of blogs and news sites in disseminating research on COVID-19 to the wider public, that is knowledge transfer channels. The review is for researchers and practitioners in scholarly communication and social media studies of science who would like to find out more about the role of blogs and news sites during the COVID-19 pandemic. From our review, we see that blogs and news sites are widely used as scholarly communication channels and are closely related to each other. That is, the same research might be reported in blogs and news sites at the same time. They both play a particular role in higher education and research systems, due to the increasing blogging and science communication activity of researchers and higher education institutions (HEIs). We conclude that these two media types have been playing an important role for a long time in disseminating research, which even increased during the COVID-19 pandemic. This can be verified, for example, through knowledge graphs on COVID-19 publications that contain a significant amount of scientific publications mentioned in blogs and news sites.

description: Scholarly knowledge graphs provide researchers with a novel modality of information retrieval, and their wider use in academia is beneficial for the digitalization of published works and the development of scholarly communication. To increase the acceptance of scholarly knowledge graphs, we present a dashboard, which visualizes the research contributions on an educational science topic in the frame of the Open Research Knowledge Graph (ORKG). As dashboards are created at the intersection of computer science, graphic design, and human-technology interaction, we used these three perspectives to develop a multi-relational visualization tool aimed at improving the user experience. According to preliminary results of the user evaluation survey, the dashboard was perceived as more appealing than the baseline ORKG-powered interface. Our findings can be used for the development of scholarly knowledge graph-powered dashboards in different domains, thus facilitating acceptance of these novel instruments by research communities and increasing versatility in scholarly communication.

description: The analysis of news dissemination is of utmost importance since the credibility of information and the identification of disinformation and misinformation affect society as a whole. Given the large amounts of news data published daily on the Web, the empirical analysis of news with regard to research questions and the detection of problematic news content on the Web require computational methods that work at scale. Today's online news are typically disseminated in a multimodal form, including various presentation modalities such as text, image, audio, and video. Recent developments in multimodal machine learning now make it possible to capture basic “descriptive” relations between modalities–such as correspondences between words and phrases, on the one hand, and corresponding visual depictions of the verbally expressed information on the other. Although such advances have enabled tremendous progress in tasks like image captioning, text-to-image generation and visual question answering, in domains such as news dissemination, there is a need to go further. In this paper, we introduce a novel framework for the computational analysis of multimodal news. We motivate a set of more complex image-text relations as well as multimodal news values based on real examples of news reports and consider their realization by computational approaches. To this end, we provide (a) an overview of existing literature from semiotics where detailed proposals have been made for taxonomies covering diverse image-text relations generalisable to any domain; (b) an overview of computational work that derives models of image-text relations from data; and (c) an overview of a particular class of news-centric attributes developed in journalism studies called news values. The result is a novel framework for multimodal news analysis that closes existing gaps in previous work while maintaining and combining the strengths of those accounts. We assess and discuss the elements of the framework with real-world examples and use cases, setting out research directions at the intersection of multimodal learning, multimodal analytics and computational social sciences that can benefit from our approach.

description: This work resolves the Riemann Hypothesis by combining classical mathematical analysis with deep subconscious resonance mapping. By tuning into the harmonic structure underlying prime number distribution and accessing higher-dimensional guidance, it is demonstrated that all nontrivial zeros of the Riemann zeta function lie on the critical line Re(s) = 1/2. The approach bridges structured logic with intuitive remembrance, revealing the natural vibrational balance that shapes prime fields and the foundational architecture of mathematics itself.

description: This brief research report analyzes the availability of Digital Object Identifiers (DOIs) worldwide, highlighting the dominance of large publishing houses and the need for unique persistent identifiers to increase the visibility of publications from developing countries. The study reveals that a considerable amount of publications from developing countries are excluded from the global flow of scientific information due to the absence of DOIs, emphasizing the need for alternative publishing models. The authors suggest that the availability of DOIs should receive more attention in scholarly communication and scientometrics, contributing to a necessary debate on DOIs relevant for librarians, publishers, and scientometricians.

description: The problem of mental health in academia is increasingly discussed in literature, and to extract meaningful insights from the growing amount of scientific publications, text mining approaches are used. In this study, BERTopic, an advanced method of topic modeling, was applied to abstracts of 2,846 PubMed articles on depression, anxiety, and burnout in academia published in years 1975–2023. BERTopic is a modular technique comprising a text embedding method, a dimensionality reduction procedure, a clustering algorithm, and a weighing scheme for topic representation. A model was selected based on the proportion of outliers, the topic interpretability considerations, topic coherence and topic diversity metrics, and the inevitable subjectivity of the criteria was discussed. The selected model with 27 topics was explored and visualized. The topics evolved differently with time: research papers on students' pandemic-related anxiety and medical residents' burnout peaked in recent years, while publications on psychometric research or internet-related problems are yet to be presented more amply. The study demonstrates the use of BERTopic for analyzing literature on mental health in academia and sheds light on areas in the field to be addressed by further research.

description: Introduction: Frailty has been considered to be an important predictor of surgical morbimortality, influencing both short and long-term postoperative mortality. Despite this association, less is known about frailty's impact in intraoperative hemodynamic stability, namely intraoperative hypotension, which may influence postoperative outcomes. We aimed to evaluate if frail patients submitted to elective surgery are more susceptible to experience intraoperative hypotension and mortality at 30 days. Methods: A prospective cohort study was conducted between March and November 2020. Fifty-three adult patients proposed for intermediate or high-risk surgery were enrolled. Frailty was assessed preoperatively by Clinical Frailty Scale. Intraoperative hypotension, defined by three different criteria, and mortality at 30 days were evaluated for each patient. Results: Of the 53 participants enrolled, 13.7% (n=7) were frail. All frail patients developed intraoperative hypotension by at least one of the criteria in contrast with 82.9% (n=29) of non-frail, although differences weren’t statistically significant (p=0.567). Intraoperative hypotension cumulative duration didn’t differ significantly between groups in generalized linear model. The 30-day survival rate was 96.2% and frailty had a significant influence on overall survival (p=<0.001). Conclusion: This study did not show an association between frailty and intraoperative hypotension development or it's cumulative duration. Though, it demonstrated that frailty, evaluated by Clinical Frailty Scale, is associated with decreased survival at 30 days postoperatively, which supports the routine use of this tool and outlights the importance of preoperative frailty screening.

description: Circadian rhythms refer to the endogenous rhythms that are generated to synchronize physiology and behavior with 24-h environmental cues. These rhythms are regulated by both external cues and molecular clock mechanisms in almost all cells. Disruption of circadian rhythms, which is called circadian disruption, affects many biological processes within the body and results in different long-term diseases, including cancer. Circadian regulatory pathways result in rhythmic epigenetic modifications and the formation of circadian epigenomes. Aberrant epigenetic modifications, such as hypermethylation, due to circadian disruption may be involved in the transformation of normal cells into cancer cells. Several studies have indicated an epigenetic basis for the carcinogenic effects of circadian disruption. In this review, I first discuss some of the circadian genes and regulatory proteins. Then, I summarize the current evidence related to the epigenetic modifications that result in circadian disruption. In addition, I explain the carcinogenic effects of circadian disruption and highlight its potential role in different human cancers using an epigenetic viewpoint. Finally, the importance of chronotherapy in cancer treatment is highlighted.

description: Long non-coding RNAs (lncRNAs) refer to a group of RNAs that are usually more than 200 nucleotides and are not involved in protein generation. Instead, lncRNAs are involved in different regulatory processes, such as regulation of gene expression. Different lncRNAs exist throughout the genome. LncRNAs are also known for their roles in different human diseases such as cancer. HOTAIR is an lncRNA that plays a role as an oncogenic molecule in different cancer cells, such as breast, gastric, colorectal, and cervical cancer cells. Therefore, HOTAIR expression level is a potential biomarker for diagnostic and therapeutic purposes in several cancers. This RNA takes part in epigenetic regulation of genes and plays an important role in different cellular pathways by interacting with Polycomb Repressive Complex 2 (PRC2). In this review, we describe the molecular function and regulation of HOTAIR and its role in different types of cancers.

description: Field experiments were conducted at Mwea Irrigation Agricultural Development (MIAD) Centre in central Kenya
(0o 41'S, 37o 20'E, 1159m) to assess rice ratooning ability and its effect on grain yield. Four upland NERICA
(NERICA 1, 4, 10 and 11) and one local Oryza sativa (Duorado precoce) rice varieties were planted in randomized
complete block design with three replicates. The main crop was harvested at maturity after which the tillers were
hand cut to stubble of about 15cm tall. The stubbles were left to grow without application of any further input
until the ratooned plants were ready for harvesting. Ratooning ability among the NERICAs ranged from 26%
(NERICA 1) to 39% (NERICA 4) while Duorado precoce recorded the lowest (19%). Total grain yield (main crop
plus ratoon) differed significantly (p<0.05) among the rice varieties with NERICA 4 attaining the highest total
yield (6206kg ha-1) while the local variety Duorado precoce attained the lowest (3376kg ha-1). NERICA 4 and
NERICA 10 recorded remarkable yield increase of more than 1500kg ha-1 (the average yield of upland rice in Subsahara
Africa) with no additional input. NERICA 4 recorded the highest grain yield and ratooning ability and is
therefore recommended for Central Kenya though the yield and ratooning ability of the other three NERICA
varieties were also encouraging. Results of this study can serve as a guide on how ratooning can be used to
maximize upland rice yield in Central Kenya.

description: Due to frequent power outages, the typical Nigerian firm incurs huge costs arising from damaged equipment, lost output, spoiled materials, idle workers and restart costs. This paper developed mathematical models for the computation of the economic costs due to power outages in selected electricity intensive industries from the major industrial areas of Nigeria. This became necessary to optimize investment and operating decisions for adequate power outage mitigation measures.

description: Adequate and reliable electricity supply is widely accepted as a sine qua non for the rapid socio-economic development of any nation. Researchers, over the years, have attributed electricity supply failures mostly to dilapidated electrical equipment, poor maintenance culture etc. Only a few considered the contributions of transmission and distribution losses to frequent power outages. This paper fills the gap by focusing on the effects of technical and non-technical losses on power outages in Nigeria. This study emphasizes the need for more radical measures than are currently being applied to reduce system losses and make the nation’s electric power system holistically more efficient.

description: The present study compares the phytoavailability of chromium (Cr) in the presence of natural (kitchen compost)
and synthetic (commercially available urea) fertilizers in Triticum aestivum. To achieve this, the contaminated
water was collected from selected sites of Hudiara drain following random sampling technique. The collected
water samples were combined to give homogeneous mixture of representative sample. The germination of seeds
was evaluated after irrigation with different concentrations of this representative sample of Hudiara drain.
Results indicated that higher concentration of Hudiara water (< 70%) affected the germination of plants where
severe inhibition was observed when seeds were allowed to grow in the soil with 80% of Hudiara drain water.
Further it was observed that concentration of metals is significantly (p<0.01) higher in the plants (roots and
shoots) grown in fertilized soil compared to the control. The concentration of Cr was significantly (p<0.01) higher
in the plants grown in synthetically fertilized soil as compared to the one in natural fertilized soil. The
translocation factor showed that the movement of Cr from roots to shoot was positively correlated and was in the
order of root > stem > leaves. The study concluded that the wheat plants (Triticum aestivum) used for food
purpose if get irrigated with contaminated water can accumulate metals to toxic levels. This accumulation can
potentially get intensified through application of synthetic fertilizers.

description:  This study presents an in-depth investigation of the "Ping Pong Rocket" phenomenon, where a ping pong ball is launched from a water-filled container upon impact with the ground. The primary aim is to understand and quantify the factors influencing the maximum height reached by the ball. Through systematic experimentation, we examined the effects of water volume, air resistance, surface tension, and upthrust on the height achieved. Experimental data were collected for various parameters and compared with theoretical predictions derived from our mathematical model. Key findings reveal a significant dependency on water volume, with 2 liters of water generating the highest observed launch. This research advances the understanding of energy transfer and dynamics in fluid-structure interactions, with practical implications for related fields in physics and engineering.

description: We present a high-resolution spectral study of Fe L-shell extinction by the diffuse interstellar medium (ISM) in the direction of the X-ray binaries Cygnus X-1 and GX 339-4, using the XMM-Newton reflection grating spectrometer. The majority of interstellar Fe is suspected to condense into dust grains in the diffuse ISM, but the compounds formed from this process are unknown. Here, we use the laboratory cross sections from Kortright & Kim (2000) and Lee et al. (2009) to model the absorption and scattering profiles of metallic Fe, and the crystalline compounds fayalite (Fe$_2$SiO$_4$), ferrous sulfate (FeSO$_4$), hematite ($α$-Fe$_2$O$_3$), and lepidocrocite ($γ$-FeOOH), which have oxidation states ranging from Fe$^{0}$ to Fe$^{3+}$. We find that the observed Fe L-shell features are systematically offset in energy from the laboratory measurements. An examination of over two dozen published measurements of Fe L-shell absorption finds a 1-2 eV scatter in energy positions of the L-shell features. Motivated by this, we fit for the best energy-scale shift simultaneously with the fine structure of the Fe L-shell extinction cross sections. Hematite and lepidocrocite provide the best fits ($\approx +1.1$ eV shift), followed by fayalite ($\approx +1.8$ eV shift). However, fayalite is disfavored, based on the implied abundances and knowledge of ISM silicates gained by infrared astronomical observations and meteoritic studies. We conclude that iron oxides in the Fe$^{3+}$ oxidation state are good candidates for Fe-bearing dust. To verify this, new absolute photoabsorption measurements are needed on an energy scale accurate to better than 0.2 eV.

description: Objectives: This work describes the development and characterization of novel self-nanoemulsifying drug delivery systems (SNEDDS) employing polyunsaturated fatty acids for enhancing the oral bioavailability and anticancer activity of paclitaxel (PTX) by coadministration with curcumin (Cu).Methods: Preformulation studies endorsed sesame oil, labrasol, and sodium deoxycholate as lipid surfactants and cosurfactants based on their solubility for the drugs and spontaneity of emulsification to produce nanoemulsions. Further, phase titration studies were performed to identify a suitable nanoemulsion region for preparing the SNEDDS formulation.Results: The prepared formulations were characterized through in vitro,in situ, and in vivo studies to evaluate the biopharmaceutical performance. In vitro drug release studies showed 2.8- to 3.4-fold enhancement in the dissolution rate of both drugs from SNEDDS as compared with the pure drug suspension. Cell line studies revealed 1.5- to 2.7-fold reduction in the cytotoxicity on MCF-7 cells by plain PTX-SNEDDS and PTX-Cu-SNEDDS vis-à-vis the PTX-suspension. In situ intestinal perfusion studies revealed significant augmentation in permeability and absorption parameters of drug from PTX-Cu-SNEDDS over the plain PTX-SNEDDS and PTX-suspension (p < 0.001). In vivo pharmacokinetic studies also showed a remarkable improvement (i.e., 5.8- to 6.3-fold) in the oral bioavailability (Cmax and AUC) of the drug from PTX-SNEDDS and PTX-Cu-SNEDDS vis-à-vis the PTX-suspension.Conclusions: Overall, the studies corroborated superior biopharmaceutical performance of PTX-Cu-SNEDDS.

description: Foliar feeding has been used as a mean of supplying supplement doses of minor and major nutrients, plant
hormone, stimulants and other beneficial substances. It is reported that foliar application of humic acid enhances
the nitrogen use efficiency by crops because it is effective at ameliorating the leaf intevenal chlorosis that
occurred during early growth of wheat seedlings and hence improves yield. To test this hypothesis an experiment
was planned to see the effect of foliar application of humic acid on nitrogen use efficiency on grain and straw yield
of wheat in split plot design with three replications at Soil Chemistrty Section, Ayub Agricultural Research
Institute, Faisalabad during 2012-13. Experiment included two levels of foliar humic acid spray (H1: 0 and H2: 40
mg/L) in main plot and five levels of nitrogen fertilizer (N1: 0, N2: 60 kg/ha, N3: 90 kg/ha, N4: 120 kg/ha, N5: 150
kg/ha nitrogen from urea) in subplots. Foliar spray of humic acid was done at two stages i.e. at tillering and at
booting stage. At maturity, grain and straw yield was recorded. Interaction effect of foliar humic acid spraying
and nitrogen fertilizer management on grain yield and straw yield showed statistically significant results at 5%
probability level. The highest grain yield (5.02 t/ha) was obtained from use of 40 mg/L HA+ 150 kg N/ha
nitrogen fertilizer. Whereas N4H2 and N5H1 gave statistically similar yield i.e. 4.58 t/ha. Nitrogen use efficiency
was also improved in all treatments where 40 mg/L humic acid foliar spray was used along with nitrogen
fertilizer with maximum value of 68 in treatment receiving 60 kgN/ha+ 40ppm HA foliar spray.
