Assessment of runoff generation capacity and total runoff contribution for different landscapes in alpine and permafrost watershed

Alpine vegetation, cold deserts, and glacial landscapes significantly impact runoff generation and convergence in cold and alpine regions. The presence of existing mountain permafrost complicates these impacts further. To better understand the specific regulation of runoff by alpine landscapes, we analyzed the spatiotemporal capacity for runoff generation and the contributions of water from different landscape types within a typical alpine permafrost watershed: the upper reaches of the Shule River (USR) basin in the Qinghai-Tibet Plateau. The analysis was informed by both field observations and simulations using the VIC model, which incorporated a new glacier module. We identified that glaciers, alpine meadows, cold deserts, and barren landscape zones as the four major runoff generation regions, collectively accounting for approximately 95 % of the USR runoff. The runoff depth in each landscape zone was calculated to express its “runoff generation capacity,” with an order of: glacier > cold desert > barren > alpine grassland > alpine meadow > shrub > swamp meadow. The alpine regions above 4000 m in altitude are the primary runoff generation areas, and the “runoff generation capacity” gradually decreases from high to low altitudes in the alpine basin. Due to seasonal variations in rainfall distribution, glacier melting, and permafrost thawing-freezing, the dominant landscape types contributing to runoff varied monthly. The simulated results indicate that permafrost plays an important role in runoff generation. Although permafrost degradation had a slight impact on the annual total runoff generated from each landscape zone (not taking into account of ground ice), seasonal runoff generated in each landscape exhibited significant changes in response to permafrost thawing. After permafrost completely thawed in each landscape zone, generated flood flow decreased, while low flow conversely increased, implying an enhanced water retention capacity of alpine landscapes following permafrost degradation. Additionally, the responses of runoff to permafrost changes varied across different alpine landscapes. These findings enhance our understanding of the mechanisms underlying runoff generation and convergence in cold and alpine watersheds of the Northern Hemisphere.

Using capacity assessments and tailored technical assistance to advance trauma informed care integration at the organizational level

BackgroundThe prevalence of trauma among individuals with HIV has prompted efforts to integrate trauma-informed care (TIC) into HIV care and treatment to improve health outcomes. A TIC Implementation Model, developed by a US capacity-building organization focuses on organizational changes, aligning cultural and physical environments, emphasizing values like safety and trustworthiness, engaging leadership, and training staff in skills-based TIC services. Despite growing research, gaps remain in understanding the relationship between organizational capacity, provider knowledge, and the dosage of technical assistance (TA) required to sustain TIC integration. Researchers investigated how the project team adapted the type and amount of TA based on initial Cultural Assessment scores (measuring core TIC values) and its impact on Implementation Status scores.MethodsThis study focuses on eight of 20 HIV care agencies in New Jersey that had largely met their TIC implementation goals by Spring 2022. As part of the TIC Implementation Model to measure agency capacity and implementation progress over time, agency staff and clients completed a Cultural Assessment (n = 72) and Physical Assessment (n = 43); staff completed a Pre/Post Training Survey (n = 296); and implementation teams at 8 agencies completed an Implementation Status Assessment Tool. Additionally, TA Logs capturing the details of TA meetings with the eight agencies were recorded by project staff. Data from these tools were analyzed in aggregate by agency using descriptive and correlational analyses.ResultsResults demonstrated responsive TA correlated with agencies’ baseline capacity. Agencies with lower capacity received significantly more frequent and extended TA encounters, which were associated with higher implementation scores and improvements in cultural environments for staff and clients (e.g., new protocols for staff response plans).ConclusionsThese findings underscore the importance of tailored TA in fostering diverse organizational cultures conducive to TIC implementation. For HIV care agencies, successful TIC implementation can impact health behaviors and outcomes for clients impacted by trauma. The TIC Implementation Model significantly advanced organizations’ ability to transform their culture and systems, increasing their capacity to implement and sustain TIC integration. These results align with existing research that emphasizes when time is invested to shift organizational culture and develop leadership, new practices can effectively be implemented and scaled-up.

Mechanism analysis and structural design of parallel-driven hydraulic wrist joint

Purpose This study aims to design a novel 3 degree-of-freedom parallel-driven hydraulic wrist (PHW) joint, characterized by a compact structure, heavy payload capacity and spherical workspace. Design/methodology/approach In this paper, the kinematics and dynamics mathematical model of PHW is analyzed based on the closed-loop vector method, screw theory and virtual work principle. And the key parameters of PHW are determined based on the singularity analysis. The integrated design method of hydraulic and mechanical systems is used, thereby enabling a hose-less configuration that fosters a low-leakage hydraulic system structure with reduced self-weight. Additionally, this research proposed a dynamic nonlinear compensation control methodology predicated on a payload model to enhance the stability and precision of trajectory tracking for PHW. Finally, several experiments have been conducted to evaluate and validate the performance of the proposed approach and the payload capacity of PHW. Findings Experiment results show that PHW has a payload-to-self-weight ratio of 4(payload 14 kg with self-weight 3.5 kg) under supply pressure 7 MPa. The experimental assessment of payload capacity substantiates the efficacy of the dynamic nonlinear compensation control method for PHW. Remarkably, the trajectory tracking errors for PHW remain under 0.03 rad, even when subjected to payloads of 10.5 and 14 kg. Originality/value This study presents an effective parallel hydraulic-driven wrist structure. This parallel structure provides a spherical workspace with flexible motion, and larger payload capacity compared with the existing robot wrist.

Working capacity level defines the specific impairment profile of the comprehensive ICF core set for multiple sclerosis

Multiple sclerosis (MS) unfavorably affects working capacity. The Comprehensive International Classification of Functioning, Disability and Health Core Set for MS (cICF-MS), issued by the World Health Organization, has not yet been extended to evaluate working capacity level (WCL). To evaluate the relative importance of cICF-MS categories in relation to WCL. Persons with MS (PwMS), N = 129, who had been referred to Lithuania’s Disability and Working Capacity Assessment Office for WCL determination, were divided into three groups according to the percentage of remaining WCL (WCL1 had 0–25%, WCL2 had 30–40%, and WCL3 had 45–55%). Data regarding the cICF-MS categories were collected through telephone interviews and patient documentation. Using the fractional ranking method, the mean values of cICF-MS impairment were ranked from the most severely affected to the least affected (rank 1–93). Ranks with the 10 highest mean values of impairment severity in each WCL group were included in a descriptive analysis. In the WCL1 and WCL2 groups, the most-affected cICF-MS categories reflected disability related to gait and motor function. The WCL3 group presented with pain, fatigue, and impairments to visual acuity, psychic stability, urination, and memory. This study has identified specific cICF-MS impairment profiles based on remaining WCL.

Exploring the innovation potential of urban space at the micro scale: a case study of Suzhou’s main urban area

As urban areas serve as spatial carriers for innovation activities, exploring the interaction between innovation and urban spaces has become a research hotspot. Previous studies have primarily focused on urban innovation capacity assessment and measurement, with less attention given to the urban innovation potential and issues such as insufficient granularity of research and weak stability in factor weighting. In this study, an urban spatial innovation potential measurement system was proposed from a demand-side perspective, the structural equation model (SEM) was employed to investigate the direct and indirect influences of factors, and micro-scale empirical analysis was conducted in the main urban area of Suzhou, China. Coupling and coordination with innovation outputs were analyzed. The results revealed that (1) the innovation potential exhibits significant spatial clustering characteristics; (2) there is clear core-periphery spatial differentiation in the innovation potential, demonstrating decreasing spatial diffusion effects with distance from the center; and (3) only 8.18% of the plots in the study area occur at the harmonized innovation coupling stage, indicating that the overall innovation conversion efficiency should be improved. This study aimed to provide a sound basis and practical references for optimizing the layout and improving the quality of urban innovation spaces from a detailed scale perspective, thereby enhancing urban competitiveness.

An integrated participatory framework for WEFE nexus strategic planning: The Jordan Valley case study.

The Jordan Valley (JV) is a critical region where the interplay of water, energy, food, and ecosystem (WEFE) dynamics presents both challenges and opportunities for sustainable development and climate change mitigation and adaptation. In such a transboundary river basin with acute nexus problems and a long history of conflicts, it is essential that conscious efforts are made to pluralize the debate and actively encourage stakeholders' empowerment, participation and fair collaboration in strategic planning. An integrated framework for participatory strategic planning in the WEFE nexus is proposed, which has been developed in the context of the JV case study. The nexus approach emphasizes decentralized, but coordinated decision making as the source of solutions, based on a clear understanding of the challenges faced. The engagement process consisted of living lab sessions where Causal Loop diagrams facilitated discussions with stakeholders by visualizing the complexity and interdependence of WEFE sectors and prioritizing the challenges faced. Community capacity assessment appraised the capacities of each community, identifying barriers to addressing their priorities. Finally, the gap analysis bridged the baseline understanding with actionable targets. The results not only highlight the pressing challenges, priorities, and leverage points for each territory but also outline pathways for fostering resilience and adaptation to the region's intertwined crises. The priorities and capacities across the three territories of the JV reveal significant disparities, reflecting the diverse socio-political, environmental, and economic contexts of the region. The methodologies and overall framework may be replicated in other regions with similar climate and challenges around the world.

Pre-operative subjective functional capacity and postoperative outcomes in adult non-cardiac surgery: asystematic review and meta-analysis.

Assessment of functional capacity is an essential part of peri-operative risk stratification. Subjective functional capacity is easier to examine than objective tests of patient fitness. However, the association between subjective functional capacity and postoperative outcomes has not been established. Four databases were searched for studies describing the associations between subjective functional capacity and postoperative outcomes in adults undergoing non-cardiac surgery. Meta-analysis was conducted among studies where functional capacity was expressed in metabolic equivalents. The primary outcome was postoperative major adverse cardiovascular events. Secondary outcomes were mortality and postoperative overall complications. We estimated the ORs of the outcomes in patients with poor functional capacity (< 4 metabolic equivalents) as compared with those with good functional capacity (≥ 4 metabolic equivalents). Random-effects models were used for the meta-analysis. We identified 7835 abstracts. After screening and a full-text review, 23 studies were selected. Evaluation methods of functional capacity included: questionnaires (n = 7); specific questions (n = 6); and subjective assessment by anaesthetists (n = 5). The probability of major postoperative adverse cardiovascular events was significantly higher in patients with poor functional capacity (OR 1.84, 95%CI 1.62-2.08) than in those with good functional capacity. Patients with poor functional capacity also had higher odds of mortality (OR 2.48, 95%CI 1.45-4.25) and postoperative complications (OR 1.85, 95%CI 1.34-2.55). Subjective functional capacity of < 4 metabolic equivalents was associated with postoperative complications including cardiovascular events and other serious outcomes. The results need to be interpreted with caution due to the diverse measures used to assess functional capacity.

Load-Bearing Capacity of Klein’s Ceiling Under Fire Conditions

The aim of this study was to determine the load-bearing capacity of Klein’s floors under fire conditions using analytical and numerical analyses. Analytical and numerical simulations were performed considering different structural variants of Klein’s floors. A numerical FEM model was developed in Abaqus to create temperature profiles of the beam-to-beam slabs and steel beams, and the fire load-bearing capacity of Klein’s celling after being exposed to fire for 30, 60, and 120 min was calculated analytically. The analytical method of assessing the fire load-bearing capacity of Klein’s floors uses temperature profiles, which allow for calculations to verify fire resistance in the time domain of different structural variants of Klein’s floors. (1) Introduction: The structural solutions of Klein’s floors are widely known, but no studies in the literature have addressed the mechanics of these elements under fire conditions. Both the beam-to-beam slab and steel beams are sensitive to high temperatures. Providing the required level of fire safety in buildings with Klein’s ceilings is a complex issue that requires detailed analysis. This often involves the assessment of technical and material solutions that are not currently used, and a verification of their fire resistance may be necessary to adapt existing buildings to the presently applicable technical and construction regulations. (2) Methodology: This study was prepared based on domestic and foreign sources, including standards presenting available methods for verifying the fire resistance of Klein’s ceilings in terms of their load-bearing capacity. A calculation scheme was indicated that takes into account the inter-beam slab, treated as a reinforced masonry element subjected to bending, and steel ceiling beams. In addition, this article presents an original method for determining the temperature profiles of individual elements of Klein’s ceilings, based on numerical methods, to determine their reduced values of material properties. The temperature profiles included in this study take into account both different construction variants of Klein’s ceilings and different ways of finishing the lower surface of these ceilings. The presented analytical method of fire load-bearing capacity assessment is supported by a calculation example. (3) Conclusions: The calculation methodology presented in this paper, which is part of the analysis of the fire load-bearing capacity of Klein’s ceilings, allows for a safe estimation of their durability in fire conditions. The presented temperature profiles of individual Klein’s ceiling elements allow for the verification of their fire resistance in terms of load-bearing capacity, in accordance with the literature on the subject. The temperature values of individual Klein’s ceiling elements, presented in the form of a table, depending on the fire duration, indicate that the applied structural solutions of the ceilings have a significant influence on the rate of temperature increase in the partition. Based on the conducted analyses, it was found that steel beams in an unplastered Klein’s ceiling lose their fire load-bearing capacity before the 30 min fire duration, defined by the standard temperature–time curve. The use of gypsum plaster with a thickness of at least 1.5 cm can provide fire resistance of the above elements for up to 120 min of fire duration. It was found that the quality of the plaster is important, influencing its adhesion to the lower surface of the ceiling. The fire resistance of the inter-beam slabs is significantly influenced by the temperature of their reinforcement, which largely depends on the distance of the reinforcement from the lower edge of the slab.

Capacity assessment of vertiports with a scheduling algorithm considering quality of service

Abstract Urban air mobility (UAM) utilising novel transportation tools is gradually being recognised as a significant means to alleviate ground transportation pressures, vertiports which serve as pivotal nodes in UAM require efficient methods for assessing its operational capacity to develop an appropriate operational strategy and help to design vertiport ground infrastructure scientifically. This study proposes a multi-dimensional assessment method for the capacity of vertiports considering throughput and quality of service based on genetic algorithm (CEGA). The method comprehensively considers constraints such as unmanned aerial vehicle (UAV) safety separation, battery endurance, number of landing vertipads and UAV speed. The experimental results indicate that the vertiport with the scheduling algorithm proposed by this study has a larger capacity and experiences fewer delay than the vertiport with first-come-first-served (FCFS) algorithm when the vertiport has the same limited number of vertipads. Different proportions of UAVs significantly affect the quality of service and the degree of operation delays. The weights of vertiport throughput and customer satisfaction are the parameters that represent the importance of throughput and customer satisfaction in the objective function of the capacity assessment model. When the weights of throughput and customer satisfaction are set to 0.8 and 0.2 respectively, the performance of this optimisation model is optimal. This study provides a novel solution for capacity assessment and operation scheduling of vertiports, laying the foundation for improving the efficiency of UAM operations.

Assessment of upper extremity functional capacity in following osteosynthesis for upper limb fractures using a novel method for determining total reachable workspace.

This study aimed to assess reachable workspace (RWS) in patients post-osteosynthesis of shoulder, elbow, or wrist fractures and explore correlations with self-reported function and kinesiophobia. An observational case-control study compared patients with fractures to a control group, utilizing questionnaires and 3D kinematic data. The sample included 66 individuals who had undergone osteosynthesis: 21 with shoulder fractures, 10 with elbow fractures, and 22 with wrist fractures. A control group of 23 participants without upper limb pathologies was also established. Inclusion criteria were ages 18-80 and recent surgery; exclusions were previous upper limb surgeries, cervical pathologies, systemic diseases or nerve injuries. RWS, the three-dimensional volume the hand can reach, was measured with participants standing. Kinesiophobia was assessed using the Tampa Scale of Kinesiophobia (TKS), and physical disability and pain were measured using the DASH questionnaire and the Numeric Pain Rating Scale (NPRS). Fracture groups exhibited significant RWS reductions (62-85%) compared to the control group, with no significant differences among the fracture types. RWS showed a high correlation with TKS (R = 0.77) and a moderate correlation with DASH (R = 0.52). RWS is a promising biomechanical parameter for assessing upper limb function post-fracture, aiding in refining rehabilitation protocols.

Total functioning capacity scale in Huntington's disease: natural course over time.

The total functioning capacity (TFC) assessment has been integral to Huntington's disease (HD) research and clinical trials, measuring disease stage and progression. This study investigates the natural progression of function in HD, focusing on changes in TFC scores related to age and CAG-repeat length, and evaluates TFC's strengths and weaknesses in longitudinal studies. Using Enroll-HD platform's clinical dataset version 5, including Registry-3, we analysed data from 21,079 participants, with 16,083 having an expanded CAG repeat. Our final analysis encompassed 15,527 patients and 52,457 visits, with TFC scores ranging from 0 to 13. Alluvial charts show that most individuals maintain maximum functional capacity over time. 3505 individuals experienced change in TFC scores, over the subsequent 4 years, 2224 (64.1%) experienced declining TFC scores, while 661 (18.6%) showed improvement within a year. The remaining 17.3% exhibited stable TFC scores. Age-related changes followed a specific sequence: occupation, household chores/finances, daily living, and care. Longer CAG-repeat lengths were linked to earlier functional decline, with some geographic regions showing earlier losses in specific domains. Reduced penetrance CAG-repeat groups exhibited different trajectories from full penetrance HD participants. When we focus on those who experienced a change in TFC score, the number of HD patients with regained functional capacity is substantial, even considering interrater variability, which may influence outcome assessments in clinical trials. The TFC effectively reflects changes in functional domains as intended. Analysis of the reduced penetrance group suggests potential selection biases in seeking medical attention earlier and for reasons unrelated to HD.

Feasibility and preliminary efficacy of a physical activity intervention in adults with lymphoma undergoing treatment

BackgroundTo determine the feasibility, acceptability, and preliminary efficacy of a 6-month tailored non-linear progressive physical activity intervention (PAI) for lymphoma patients undergoing chemotherapy.MethodsPatients newly diagnosed with lymphoma (non-Hodgkin (NHL) or Hodgkin (HL)) were randomized into the PAI or healthy living intervention (HLI) control (2:1). Feasibility was assessed by examining accrual, adherence, and retention rates. Participants completed assessments of exercise capacity (VO2 peak and 6-min walk distance (6MWD)), objective and self-reported levels of physical activity, MRI-derived cardiovascular functioning (Left Ventricular Ejection Fraction [LVEF], stroke volume, and cardiac output), and self-reported health-related and disease-specific quality of life and self-efficacy for exercise at baseline, 3, and 6 months.ResultsOne hundred and forty-five individuals were screened with 23 of 84 eligible patients agreeing to participate (27%). Three participants withdrew before baseline testing. Out of the 20 participants randomized to the PAI (n = 13) and HLI groups (n = 7), 18 completed the intervention resulting in an overall retention rate of 78%. The adherence rates to the PAI and HLI were 85% and 87%, respectively. One non-serious adverse event was registered. VO2 peak ranged from 15.5–28.0 ml/kg/min at baseline and participants in both groups improved by 6 months. Physical activity levels and cardiovascular function were reduced prior to treatment but did not deteriorate further.ConclusionsImplementing a tailored PAI in adults with lymphoma during active treatment is feasible, was well received by participants and shows preliminary efficacy for limiting a decline in function during treatment. Potential Implications for Cancer Survivors: Physical activity may be beneficial for improving exercise capacity and health-related quality of life in patients undergoing chemotherapy.Trial registration#NCT01719562 ClinicalTrials.gov.

Data-Driven Decision Support to Guide Sustainable Grazing Management

Data-driven decision support can help guide sustainable grazing management by providing an accurate estimate of grazing capacity, in coproduction with managers. Here, we described the development of a decision support model to estimate grazing capacity and illustrated its application on two sites in the western United States. For the Montgomery Pass Wild Horse Territory in California and Nevada, the upper limit estimated in the capacity assessment was 398 horses and the current population was 654 horses. For the Eagle Creek watershed of the Apache–Sitgreaves National Forest of eastern Arizona, the lower end of capacity was estimated at 1560 cattle annually, compared to the current average of 1090 cattle annually. In addition to being spatio-temporally comprehensive, the model provides a repeatable, cost-effective, and transparent process for establishing and adjusting capacity estimates and associated grazing plans that are supported by scientific information, in order to support livestock numbers at levels that are sustainable over time, including levels that are below average forage production during drought conditions. This modeling process acts as a decision support tool because it enables different assumptions to be used and explored to accommodate multiple viewpoints during the planning process.

Assessment of microplastic ecological risk and environmental carrying capacity of agricultural soils based on integrated characterization: A case study.

Microplastic pollution in agricultural soils poses a significant threat to soil quality and environmental sustainability. This study investigated the composition, abundance, distribution, ecological risk, and environmental carrying capacity of microplastic pollution in the Tarim River Basin (TRB), China. The risk quotient combined with soil environmental carrying capacity (SECC) approaches was proposed to evaluate ecological risks and soil sustainability. Microplastic abundances ranged from 0 to 4000 items/kg (average=570 items/kg), with polyethylene (PE) polytetrafluoroethylene (PTFE) and polypropylene (PP) as dominant polymers. In addition, various factors affecting the occurrence of microplastics were analyzed. Agricultural mulching and drip irrigation were associated with higher microplastic levels. The risk assessment showed that among the different shapes, size ranges and categories of microplastics, fragmented (film), large-sized microplastics and PE had the highest risk, respectively. While current levels are within SECC limits, early warning model predicts PE and PP may reach threshold limits in recent years. This study provides crucial insights for managing microplastic pollution in agricultural regions, emphasizing the need for targeted mitigation strategies to maintain soil ecology sustainability.
