Identifying mental health discussion topic in social media community: subreddit of bipolar disorder analysis

Online platforms allow individuals to connect with others, share experiences, and find communities with similar interests, providing a sense of belonging and reducing feelings of isolation. Numerous previous studies examined the content of online health communities to gain insights into the sentiments surrounding mental health conditions. However, there is a noticeable gap in the research landscape, as no study has specifically concentrated on conducting an in-depth analysis or providing a comprehensive visualization of Bipolar disorder. Therefore, this study aimed to address this gap by examining the Bipolar subreddit online community, where we collected 1,460,447 posts as plain text documents for analysis. By employing LDA topic modeling and sentiment analysis, we found that the Bipolar disorder online community on Reddit discussed various aspects of the condition, including symptoms, mood swings, diagnosis, and medication. Users shared personal experiences, challenges, and coping strategies, seeking support and connection. Discussions related to therapy and medication were prevalent, emphasizing the importance of finding suitable therapists and managing medication side effects. The online community serves as a platform for seeking help, advice, and information, highlighting the role of social support in managing bipolar disorder. This study enhances our understanding of individuals living with bipolar disorder and provides valuable insights and feedback for researchers developing mental health interventions.
Resolving an inconsistency in the estimation of the energy for excitation of cardiac muscle contraction

In the excitation of muscle contraction, calcium ions interact with transmembrane transporters. This process is accompanied by energy consumption and heat liberation. To quantify this activation energy or heat in the heart or cardiac muscle, two non-pharmacological approaches can be used. In one approach using the “pressure-volume area” concept, the same estimate of activation energy is obtained regardless of the mode of contraction (either isovolumic/isometric or ejecting/shortening). In the other approach, an accurate estimate of activation energy is obtained only when the muscle contracts isometrically. If the contraction involves muscle shortening, then an additional component of heat associated with shortening is liberated, over and above that of activation. The present study thus examines the reconcilability of the two approaches by performing experiments on isolated muscles measuring contractile force and heat output. A framework was devised from the experimental data to allow us to replicate several mechanoenergetics results gleaned from the literature. From these replications, we conclude that the choice of initial muscle length (or ventricular volume) underlies the divergence of the two approaches in the estimation of activation energy when the mode of contraction involves shortening (ejection). At low initial muscle lengths, the heat of shortening is relatively small, which can lead to the misconception that activation energy is contraction mode independent. In fact, because cardiac muscle liberates heat of shortening when allowed to shorten, estimation of activation heat must be performed only under isometric (isovolumic) contractions. We thus recommend caution when estimating activation energy using the “pressure-volume area” concept.
Karl von Lindener's Sunspot Observations during 1800 – 1827: Another Long-Term Dataset for the Dalton Minimum

On a centennial timescale, solar activity oscillates quasi-periodically and also tends to get into a low-activity period. The Dalton Minimum (c.a. 1790s–1820s) was one of such low-activity periods that had been captured in telescopic sunspot observations. However, it has been challenging to analyse the Dalton Minimum, as contemporary source records remained mostly unpublished and almost inaccessible for the scientific community. Recent studies have established reliable datasets for sunspot group number, sunspot number, and sunspot positions. This study further analyzes independent Silesian sunspot observations from 1800 to 1827 archived in a manuscript the Library WrocławUniversity (Ms AKC.1985/15), complements it with the metadata for the observer Karl Christian Reinhold von Lindener. We identified 547 days of sunspot observations in these records and derived the sunspot group number, individual sunspot number, and sunspot positions between 1800 and 1827. The results of this study have significantly revised the von Lindener’s sunspot group number, which was only known for 517 days in scientific databases, and remove contamination from general descriptions. Using our results, we extend investigations into individual sunspots and derived their positions. In our analysis, we locate von Lindener’s sunspot positions in both solar hemispheres and contrast the Dalton Minimum with the Maunder Minimum, adding further independent credits to the previous results for Derfflinger and Prantner’s datasets. Sunspot positions are also slightly biased towards the northern solar hemisphere in early Solar Cycle 6 (1812 – 1813). The high-latitude sunspot positions indicate the onset of Solar Cycle 7 as early as June 1822.
On a Collection of Reptilian Bones from the Oolite of Stow-on-the-Wold, Gloucestershire

Reptilian bones, first observed by Mr. C. I. Gardiner in 1935, are found in two quarries in the Chipping Norton Limestone (top of Inferior Oolite, fusca and zigzag hemerae). These two quarries are the New Park Quarry, about 2½ miles N.W. of Stow-on-the-Wold, and the Oakham Quarry which lies about a mile W.N.W. of Little Compton. The bones occur in a hard cream-coloured limestone which is worked for road-metal. Fossils other than reptilian remains are not common, but among those found in the New Park Quarry is an ammonite determined by Mr. J. W. Tutcher as Parkinsonia neuffensis Oppel. The great majority of the bones come from the New Park Quarry, but the Oakham Quarry yielded certain of the crocodilian, theropod, and sauropod bones.
Geological Microseismic Fracture Mapping - Methodologies for Improved Interpretations Based on Seismology and Geologic Context

Summary The results of microseismic monitoring of hydraulic fracture treatments are significantly more valuable when a high-confidence interpretation of results can be done. The most common approach is to look for trends, or directions, along which microseismic events line up that would indicate the direction of induced fractures. This type of interpretation is more difficult when the signal is low or when the events appear to define multiple directions. Analysis of geologic structures in the area of the reservoir can provide useful information to support or eliminate interpretations of apparent trends as stimulated fractures, as well as provide an explanation for fracture trends that deviate from the expected orientation from the in-situ stress directions. In some cases, structural geology observed at the surface can be extrapolated to the subsurface to aid the interpretation. When seismic reflection scale horizon and fault interpretations are available, they can be used to infer that smaller scale faults and fractures of similar orientation may have been activated at the wellbore. Inversion of seismic source mechanisms for microseismic events provides the most wellconstrained parameters to describe the failure mechanisms of the hydraulic fracture treatment, and by combining this information with the geologic context a better understanding of the reservoir rock behavior during the stimulation treatment can be developed. In this paper, examples will be presented that describe interpretations of microseismic monitoring results based on geologic context and confirmed by source mechanism inversions.
Smart Management of Energy Storage in Microgrid: Adapting the Control Algorithm to Specific Industrial Facility Conditions

The article introduces a method for optimizing energy storage system scheduling in industrial microgrids. It employs a PSO-based heuristic algorithm using daily generation and load forecasts. The objective is economic optimization, minimizing energy costs, and maximizing profits. Market energy prices and distributor tariffs are the base of the objective function. An algorithm maintains the plan by controlling storage power based on real-time microgrid measurements, aligning with the intended power exchange curve. Due to PSO’s ability to perform multidimensional optimization, it is possible to find the global optimum of the objective function. To validate the practical applicability of this approach, it is exemplified through its implementation within a real-world industrial microgrid setting. The presented results indicate the method’s effectiveness but also show its weaknesses. For the two considered cases, a decrease in operating costs of 6.7% and 10.8% was achieved, respectively. On the other hand, the best results are obtained for shorter forecasts, which is why the algorithm, despite long planning periods, revises the ESS operation plan whenever there are significant deviations between the forecast and the actual power.
Effect of submerged curing on properties of cemented paste backfill

ABSTRACT Mine stopes are often characterised by near-saturate conditions from constant water inflow from the ore body. Although significant research has been conducted on mechanical properties of cemented paste backfill, there are limited studies on curing practices that reflect saturate conditions. This study examines the effects of submerged curing to simulate saturate conditions. The results indicate that observed dark grey colouration associated with submerged curing is similar to ‘greening effect’ observed in concrete material containing Ground Granulated Blast-furnace Slag. Our study indicates that submerged curing has limited adverse material effects and is effective in simulating near-saturated conditions.
Association Between Hypnotic Use and All-Cause Mortality in Patients with Chronic Obstructive Pulmonary Disease and Insomnia

Purpose Hypnotics are commonly prescribed in patients with COPD to manage insomnia. Given the considerable risks associated with these drugs, the aim of the study was to evaluate the risk of all-cause mortality associated with hypnotics in a cohort of veterans with COPD presenting with insomnia. Methods We conducted a retrospective cohort study that used Veterans Health Administration Corporate Data Warehouse with data supplemented by linkage to Medicare, Medicaid, and National Death Index data from 2010 through 2019. The primary outcome was all-cause mortality. Analyses were conducted using propensity score 1:1 matching to balance baseline characteristics. Results Of the 5759 veterans with COPD (mean [SD] age, 71.7 [11.2]; 92% men), 3585 newly initiated hypnotic agents during the study period. During a mean follow-up of 7.4 (SD, 2.7) years, a total of 2301 deaths occurred, with 65.2 and 48.7 total deaths per 1000 person-years among hypnotic users and nonusers, respectively. After propensity matching, hypnotic use was associated with a 22% increased risk of mortality compared with hypnotic nonusers (hazard ratio [HR] 1.22; 95% confidence interval [CI],1.11–1.35). The benzodiazepine receptor agonists (BZRAs) group experienced a higher incidence rate of all-cause mortality compared to hypnotic nonusers (Incidence rate ratio [IRR] 1.27; 95% CI, 1.14–1.43). Conversely, the mortality rate of non-BZRA hypnotics decreased after the first 2 years and was not significantly different for hypnotic nonusers (IRR 1.04; 95% CI, 0.82–1.11). Conclusion Among patients with COPD and insomnia, treatment with hypnotics was associated with a higher risk of all-cause mortality. The association was observed in patients prescribed BZRAs. The risk of mortality for non-BZRAs moderated after the first 2 years, indicating a class effect.
14C Dating and Stable Carbon Isotopes of Soil Organic Matter in Forest–Savanna Boundary Areas in the Southern Brazilian Amazon Region

This study, which was carried out in the southern Brazilian Amazon region (Rondônia state and Humaitá, Southern Amazon state), presents and discusses the significance of carbon isotope data measured in soil profiles collected across natural boundaries of forest to savanna vegetation. The main objective of this study was to evaluate the expansion-regression dynamics of these vegetation units in relation to climate changes during the Holocene. 14C data from charcoal, soil organic matter (SOM) and its component humin fraction indicate that the organic matter in the studied soils is essentially Holocene in origin. 13C data indicate that C3 type plants were the dominant vegetation at all study areas in the early Holocene, and during the entire Holocene, in the forest sites of Central Rondônia state and in the forest site 50 km from the city of Humaitá. 13C data also indicate that C4 plants have influenced significantly the vegetation at the transitional forest and the Cerrado (wooded savanna) sites of Southern Rondônia state and the forest ecosystem located 20 km from the Humaitá city. These typical C4 type isotopic signatures probably reflect a drier climate during the mid-Holocene. The 13C records representing probably the last 3000 yr show an expansion of the forest, due to a climatic improvement, in areas previously occupied by savanna vegetation. These results and other published data for the Amazon region indicate that the areas representing today's forest-savanna boundaries have been determined by significant vegetation changes during the Holocene. The boundary between forest and savanna vegetation seems to be quite sensitive to climatic change and should be the focus of more extensive research to correlate climate and past vegetation dynamics in the Amazon region.
The Implementation of Mobile Technology in Organizations: Expanding Individual Use Contexts

Mobile computing devices such as personal digital assistants, smart mobile phones, and other handheld computing devices hold much promise in terms of their organizational application. Many existing models of the individual acceptance and implementation of information technology in organizational contexts have been developed in the era of “at the office” computing such as MIS, office automation, groupware, and so forth. We conducted two in-depth case studies of the implementation of mobile technology in healthcare organizations. The studies highlight interrelated individual use contexts due to the mobility of the technology: the individual as employee, as professional, as private user, and as member of society. The cases show that influences emanating from these use contexts impacted on the individual adoption of the technology within the organization. While broad extra-organizational influences are incorporated in some existing individual technology adoption models, we show that it becomes relevant to accommodate these influences more specifically in research models of mobile computing in organizations. Based on the extant literature and the case study data we pave the way toward more comprehensive models of the adoption and implementation of mobile technologies in organizations.
Whole-Genome Analysis of Termite-Derived Bacillus velezensis BV-10 and Its Application in King Grass Silage

Bacillus velezensis (B. velezensis) is a cellulose-degrading strain that has the potential as an additive in fermented feed. B. velezensis BV-10 was isolated and screened from the termite gut. We sequenced the whole genome of this new source of B. velezensis to reveal its potential for use in cellulose degradation. Whole-genome sequencing of B. velezensis BV-10 showed that it has a circular chromosome of 3929792 bp containing 3873 coding genes with a GC content of 45.51% and many genes related to cellulose, hemicellulose, and lignin degradation. King grass silage was inoculated with B. velezensis BV-10 and mixed with other feed additives to assess the effect of B. velezensis BV-10 on the fermentation quality of silage. Six treatment groups were established: the control, B. velezensis BV-10, molasses, cellulase, B. velezensis BV-10 plus molasses, and B. velezensis BV-10 plus cellulase groups. After 30 days of silage-fermentation testing, B. velezensis BV-10 was found to rapidly reduce the silage pH value and significantly reduce the acid-detergent fiber (ADF) content (p < 0.05). The addition of B. velezensis BV-10 plus molasses and cellulase in fermented feed significantly reduced the silage neutral-detergent fiber and ADF content and promoted organic-acid accumulation (p < 0.05). The above results demonstrate that B. velezensis BV-10 promotes the fermentation quality of silage and that this effect is greater when other silage-fermentation additives are included. In conclusion, genes involved in cellulose degradation in B. velezensis BV-10 were identified by whole-genome sequencing and further experiments explored the effects of B. velezensis BV-10 and different feed additives on the fermentation quality of king grass silage, revealing the potential of Bacillus velezensis as a new silage additive.
Anxiety, Depression, Quality of Life, and Family Support Among Family Caregivers of Children with Disabilities

Purpose To investigate the family support, anxiety, depression, health-related quality of life (HRQoL), and their associations among parents and grandparents of children with disabilities. Methods This is a cross-sectional study and a total of 327 family caregivers were included. Chi-square test, Mann–Whitney U-test, and two independent t-test were used to identify the intergenerational differences in sociodemographic characteristics, received family support, anxiety, depression, and HRQoL. Eight generalized linear models were developed to examine the associations in both generations. Results Parents and grandparents were most in need of rehabilitation and financial support, but both populations received the least amount of financial support. 33.6% and 36.1% of family caregivers had the risk of anxiety and depression and found no significant intergenerational differences. As for HRQoL, intergenerational differences were found in the physical component score, but not found in the mental component score. Among parents, childcare support of respite care and household tasks assistance was negatively associated with their depression (p<0.05), professional support of appropriate surgery for children (p<0.05) and psychological support from professional psychologists (p<0.01) were negatively associated with their anxiety and depression, psychological support from relatives and friends was negatively associated with their depression (p<0.05) whereas was positively associated with their mental HRQoL (p<0.01). As for grandparents, financial support for daily living expenses was negatively associated with depression (p<0.05), and psychological support from families was negatively associated with depression (p<0.05) whereas was positively associated with mental HRQoL (p<0.05). However, no relationship was found between family support and anxiety among grandparents. Notably, no association was found between family support and physical HRQoL among both populations. Conclusion Both parents and grandparents had high risks of anxiety, depression and low levels of mental HRQoL. To efficiently improve psychological health, care providers and policymakers may consider intergenerational differences and provide targeted family support.
Concurrent Mixing and Cooling of Melts under Iceland

The compositions of 75 melt inclusions, their host olivines and 49 whole-rock samples of their carrier lavas have been determined. These compositions were added to a compilation of the trace element composition of 243 melt inclusions from 10 eruptions in the neovolcanic zones of Iceland and used to investigate melt mixing processes. Whereas the compositional variability of whole-rock samples from single eruptions is limited, there are significant compositional differences between eruptions. The compositions of inclusions are more variable than those of whole-rock samples of their carrier lava. On a flow-by-flow basis, the average composition of trace element ratios such as La/Yb in the inclusions is similar to that of their carrier lava. These observations indicate that, for each lava flow, melts with compositions similar to those of the inclusions crystallized and mixed to produce the magma that transported the host olivines to the surface. Although many of the olivines are not in Mg–Fe equilibrium with their host melt, they are not accidental xenocrysts because they crystallized from melts similar to those that mixed to form the carrier magma. The trace element variability of melt inclusions drops with decreasing forsterite content of the host olivine. This relationship is observed both within single flows and in the compilation of data from 10 flows. Concurrent mixing and crystallization dominate the compositional evolution of basaltic melts in lower crustal magma chambers. This coupled mixing and cooling is likely to result from convective motions in magma chambers. The rate of change of the mixing parameter, M, with temperature of the melt is dM/dT = 0·0094 ± 0·0036 per °C. This relative rate may be used to constrain the fluid dynamics of basaltic magma chambers.
Dissolution precipitation creep versus crystalline plasticity in high-pressure metamorphic serpentinites

Abstract Serpentinite is widely assumed to constitute weak material in subduction zones and to play an essential role for the development of a subduction channel. Information on deformation mechanisms and appropriate rheological models to describe these large-scale flow processes can only be obtained from natural serpentinites exhumed from ancient subduction zones. We examine the microstructural record of HP-metamorphic (P c. 2±0.5 GPa, T c. 550±50 °C) serpentinites exposed in the Zermatt–Saas zone, Western Alps, using optical and scanning electron microscopy with electron backscatter diffraction (EBSD). The schistose and compositionally layered rocks show pervasive small-scale folding. There is no evidence for any significant deformation by dislocation creep. Instead, the microfabrics including strain shadows and crenulation cleavage indicate that high strain is accumulated by dissolution precipitation creep. In terms of rheology, this suggests Newtonian behaviour and a low viscosity for the long-term flow of serpentinites in deeper levels of subduction zones. This does not preclude dislocation creep and a power law rheology at higher stress levels, as realized at local sites of stress concentration and transient episodes of post-seismic creep.
The Barriers to Accessible Tourism in Phuket

The concept of accessible tourism is centered on advocacy for the rights of individuals with disabilities to participate in tourism activities. The study aims to close a gap in the literature by identifying the barriers to achieving accessible tourism in Phuket and contributing to tourism development by establishing a framework for tourism stakeholders. An exploratory study design was applied, and empirical data were gathered through in-depth interviews with 16 professionals residing in Phuket, Thailand. The data were analyzed thematically to identify barriers and establish an exploratory framework for tourism stakeholders. A five-dimensional exploratory framework emerged in the process. The results revealed obstacles preventing Phuket from fully engaging in accessible tourism and increasing its global market share in this emerging market segment. Moreover, the findings contribute to the field of accessibility research. The article concludes by discussing implications for tourism stakeholders.
