description: We study adiabatic and isocurvature perturbation spectra produced by a period of cosmological inflation driven by two scalar fields. We show that there exists a model-independent consistency condition for all two-field models of slow-roll inflation, despite allowing for model-dependent linear processing of curvature and isocurvature perturbations during and after inflation on super-horizon scales. The scale-dependence of all spectra are determined solely in terms of slow-roll parameters during inflation and the dimensionless cross-correlation between curvature and isocurvature perturbations. We present additional model-dependent consistency relations that may be derived in specific two-field models, such as the curvaton scenario.

description: Abstract: We provide a Kazakh whole genome sequence (MJS) and analyses with the largest comparative Kazakh genomic data available to date. We found 102,240 novel SNVs and a high level of heterozygosity. ADMIXTURE analysis confirmed a significant proportion of variations in this individual coming from all continents except Africa and Oceania. A principal component analysis showed neighboring Kalmyk, Uzbek, and Kyrgyz populations to have the strongest resemblance to the MJS genome which reflects fairly recent Kazakh history. MJS’s mitochondrial haplogroup, J1c2, probably represents an early European and Near Eastern influence to Central Asia. This was also supported by the heterozygous SNPs associated with European phenotypic features and strikingly similar Kazakh ancestral composition inferred by ADMIXTURE. Admixture (f3) analysis showed that MJS’s genomic signature is best described as a cross between the Neolithic East Asian (Devil’s Gate1) and the Bronze Age European (Halberstadt_LBA1) components rather than a contemporary admixture.

description: Long-term Web archives comprise Web documents gathered over longer time periods and can easily reach hundreds of terabytes in size. Semantic annotations such as named entities can facilitate intelligent access to the Web archive data. However, the annotation of the entire archive content on this scale is often infeasible. The most efficient way to access the documents within Web archives is provided through their URLs, which are typically stored in dedicated index files. The URLs of the archived Web documents can contain semantic information and can offer an efficient way to obtain initial semantic annotations for the archived documents. In this paper, we analyse the applicability of semantic analysis techniques such as named entity extraction to the URLs in a Web archive. We evaluate the precision of the named entity extraction from the URLs in the Popular German Web dataset and analyse the proportion of the archived URLs from 1,444 popular domains in the time interval from 2000 to 2012 to which these techniques are applicable. Our results demonstrate that named entity recognition can be successfully applied to a large number of URLs in our Web archive and provide a good starting point to efficiently annotate large scale collections of Web documents.

description: To drive innovation and competitiveness, organisations need to foster the development and broad adoption of data technologies, value-adding use cases and sustainable business models. Enabling an effective data ecosystem requires overcoming several technical challenges associated with the cost and complexity of management, processing, analysis and utilisation of data. This chapter details a community-driven initiative to identify and characterise the key technical research priorities for research and development in data technologies. The chapter examines the systemic and structured methodology used to gather inputs from over 200 stakeholder organisations. The result of the process identified five key technical research priorities in the areas of data management, data processing, data analytics, data visualisation and user interactions, and data protection, together with 28 sub-level challenges. The process also highlighted the important role of data standardisation, data engineering and DevOps for Big Data.

description: We introduce the STEM (Science, Technology, Engineering, and Medicine) Dataset for Scientific Entity Extraction, Classification, and Resolution, version 1.0 (STEM-ECR v1.0). The STEM-ECR v1.0 dataset has been developed to provide a benchmark for the evaluation of scientific entity extraction, classification, and resolution tasks in a domain-independent fashion. It comprises abstracts in 10 STEM disciplines that were found to be the most prolific ones on a major publishing platform. We describe the creation of such a multidisciplinary corpus and highlight the obtained findings in terms of the following features: 1) a generic conceptual formalism for scientific entities in a multidisciplinary scientific context; 2) the feasibility of the domain-independent human annotation of scientific entities under such a generic formalism; 3) a performance benchmark obtainable for automatic extraction of multidisciplinary scientific entities using BERT-based neural models; 4) a delineated 3-step entity resolution procedure for human annotation of the scientific entities via encyclopedic entity linking and lexicographic word sense disambiguation; and 5) human evaluations of Babelfy returned encyclopedic links and lexicographic senses for our entities. Our findings cumulatively indicate that human annotation and automatic learning of multidisciplinary scientific concepts as well as their semantic disambiguation in a wide-ranging setting as STEM is reasonable.

description: Saccharodite ponapeana (Fennah, 1956) new combination
 Levu matsumurae ponapeana Fennah, 1956a: 175
(Fig. 277n)
 Redescription. Forewings 1.9 times longer than wide, length: male 2.2–2.5 mm (mean = 2.4, n = 9), female 2.5– 2.9 mm (mean = 2.8, n = 10). Colour stramineous to light brown (in some specimens, but not in holotype, light orange-brown); margins of facial carinae and middle of pronotum tinted with orange; fore tibiae and junction of frons and clypeus often distinctly orange and some specimens with scutellum bright orange (but not in holotype). Forewings faintly infuscated from tip of Cu to base of Ms1, around base of Ms2, and along apical crossveins; veins stramineous but some parts of Sc, R, and M orange to orange-brown; base of Sc+ R with 1, rarely with 2 or 3 faint dark spots. In profile junction of vertex and face slightly angulated; subantennal processes well separated from margins of facial carinae. Forewings with venation as in Sa. basipunctulata (Melichar). Male genitalia with apical portion of aedeagus impressed on dorsal side, ending in 2 short lobes.
 Etymology. The species name is a latinized adjective (ponapeanus, -a, -um = relating to Ponape).
 Type material. Holotype ♂ (forewing 2.4 mm), MICRONESIA: PONAPE ISLAND; labels 1) Ag. Exper. Sta. / Ponape Id. / June–Sept. 50/ P.A. Adams 2) Levu matsumurae / ponapeana/ Fenn. (USNM #62159).
 Other material examined. MICRONESIA: PONAPE ISLAND: Colonia, hydroelectric plant, 9.VIII.1946, 3 ♂ 5 ♀, H.K. Townes, R. G. Oakley; Tolotom, VI–IX.1950, 1 ♂, P.A. Adams (all USNM); Palaug, W. Coast, 15 m, 10.I.1953, 1 ♂ 1 ♀, J.L. Gressitt; Mt. Tamatamansakir, 100m, 11.I.1953, 3 ♂ 6 ♀, Gressitt; SE, Nanponmal, 7.I.1953, 1 sex unknown, Gressitt (all BPBM).
 Distribution. Ponape Island, Micronesia.
 Diagnosis. Saccharodite ponapeana is closely related to Sa. basipunctulata (Melichar) which occurs in Truk and Palau. Although most specimens can be easily distinguished from that species by the orange coloration on head, thorax, and forewing veins, other specimens show no clear differences to Sa. basipunctulata. Sa. ponapeana may, therefore, be a subspecies of Sa. basipunctulata.

description: Nuclear spins are highly coherent quantum objects. In large ensembles, their control and detection via magnetic resonance is widely exploited, e.g. in chemistry, medicine, materials science and mining. Nuclear spins also featured in early ideas and demonstrations of quantum information processing. Scaling up these ideas requires controlling individual nuclei, which can be detected when coupled to an electron. However, the need to address the nuclei via oscillating magnetic fields complicates their integration in multi-spin nanoscale devices, because the field cannot be localized or screened. Control via electric fields would resolve this problem, but previous methods relied upon transducing electric signals into magnetic fields via the electron-nuclear hyperfine interaction, which severely affects the nuclear coherence. Here we demonstrate the coherent quantum control of a single antimony (spin-7/2) nucleus, using localized electric fields produced within a silicon nanoelectronic device. The method exploits an idea first proposed in 1961 but never realized experimentally with a single nucleus. Our results are quantitatively supported by a microscopic theoretical model that reveals how the purely electrical modulation of the nuclear electric quadrupole interaction, in the presence of lattice strain, results in coherent nuclear spin transitions. The spin dephasing time, 0.1 seconds, surpasses by orders of magnitude those obtained via methods that require a coupled electron spin for electrical drive. These results show that high-spin quadrupolar nuclei could be deployed as chaotic models, strain sensors and hybrid spin-mechanical quantum systems using all-electrical controls. Integrating electrically controllable nuclei with quantum dots could pave the way to scalable nuclear- and electron-spin-based quantum computers in silicon that operate without the need for oscillating magnetic fields.

Functional mobility
Illness severity

description: Abstract: Background: Reduced mobility may be responsible for functional decline and acute sarcopenia in older hospitalised patients. The drivers of reduced in-hospital mobility are poorly understood, especially during the early phase of acute hospitalisation. We investigated predictors of in-hospital activity during a 24-h period in the first 48 h of hospital admission in older adults. Methods: This was a secondary analysis of a prospective repeated measures cohort study. Participants aged 75 years or older were recruited within the first 24 h of admission. At recruitment, patients underwent a baseline assessment including measurements of pre-morbid functional mobility, cognition, frailty, falls efficacy, co-morbidity, acute illness severity, knee extension strength and grip strength, and consented to wear accelerometers to measure physical activity during the first 7 days (or until discharge if earlier). In-hospital physical activity was defined as the amount of upright time (standing or walking). To examine the predictors of physical activity, we limited the analysis to the first 24 h of recording to maximise the sample size as due to discharge from hospital there was daily attrition. We used a best subset analysis including all baseline measures. The optimal model was defined by having the lowest Bayesian information criterion in the best-subset analyses. The model specified a maximum of 5 covariates and used an exhaustive search. Results: Seventy participants were recruited but eight were excluded from the final analysis due to lack of accelerometer data within the first 24 h after recruitment. Patients spent a median of 0.50 h (IQR: 0.21; 1.43) standing or walking. The optimal model selected the following covariates: functional mobility as measured by the de Morton Mobility Index and two measures of illness severity, the National Early Warning Score, and serum C-reactive protein. Conclusions: Physical activity, particularly in the acute phase of hospitalisation, is very low in older adults. The association between illness severity and physical activity may be explained by symptoms of acute illness being barriers to activity. Interdisciplinary approaches are required to identify early mobilisation opportunities.
title: Potential of hordein as a biodegradable food packaging material
Creators: name: Ren, Zehui
Publisher: name: University of Reading
Year: 2026

description: Conventional plastic packaging is almost non-degradable, leading to significant 
environmental concerns. As a result, developing biodegradable packaging materials has 
attracted considerable attention from both industry and researchers. This study explores 
the potential of hordein, a protein extracted from spent barley, as a biodegradable 
packaging material. The high glutamine content and presence of hydrophobic amino acids, 
such as proline, leucine, and valine, endow hordein with strong aggregation properties 
and notable hydrophobicity. 
However, hordein-based films tend to have poor mechanical properties. Therefore, 
addition of individual plasticizers, glycerol (GLY) and PEG400 and their combinations were 
investigated in this research in order to enhance its property. The composite plasticizer 
formed by 25% PEG and 75% GLY demonstrated a synergistic effect, and significantly 
improved tensile strength and elongation at break of hordein film. Furthermore, the optical 
property of hordein film was also optimized in this research. Heat treatment was able to 
unfold the protein structure, exposing thiol groups to promote cross-linking through 
disulfide bonds and strengthening the protein network. Similarly, transglutaminase (TGase) 
could induce covalent cross-linking by forming isopeptide bonds between glutamine and 
lysine residues. To further enhance the mechanical properties of the hordein films, heat 
treatment at 85oC for 30 mins and TGase added at 0, 10, 20, 30 and 40 U/g were applied 
to assess their impacts on hordein film quality. Heat treatment produced a thinner film 
without compromising its mechanical property, while 20 U/g TGase achieved optimal 
mechanical properties. Although improvements were observed, the mechanical properties 
still fell short of currently used competing alternatives. 
Given hordein's excellent hydrophobicity and UV-blocking properties, the possibility of 
using hordein as a supplementary ingredient to enhance the properties of starch-based 
films was explored in this work. Starch films tend to be inherently brittle and sensitive to 
moisture, despite their superior film-forming ability. Corn starch was identified as the 
optimal base material for film production, outperforming potato and wheat starch in 
comparative analyses. Hordein was incorporated into the corn starch matrix at varying 
Abstract
10
mass ratios (10%, 20%, 30% and 40%) to assess its effect on the properties of starch film. 
The results showed that the addition of hordein significantly increased film thickness, 
tensile strength (TS), and UV-blocking performance of starch film. 
Overall, this study provides valuable insights into the characteristics of hordein and its 
potential application in the development of biodegradable food packaging films, offering a 
promising alternative to conventional plastic materials.

XL029 associated with the leaves of Panax notoginseng. The anti-agricultural pathogenic fungal assay indicated that compound 1 displayed significant activity against all tested fungi with minimum inhibitory concentrations (MIC) values from 25 to 3.1 μg/mL, while compound 2 displayed activity against all tested fungi except for Rhizoctonia solani and Fusarium oxysporum with MIC values from 50 to 12.5 μg/mL. Furthermore, compounds 1–2 also exhibited significant inhibitory activity against eight of thirteen tested bacteria with MIC values ranging from 50 to 6.3 μg/mL.
Intense boundary emission destroys normal radio-frequency plasma sheath

description: Plasma sheath is the non-neutral space charge region that isolates bulk plasma from boundary. Radio-frequency (RF) sheathes are formed when applying RF voltage to electrodes. Generally, applied bias is mainly consumed by RF sheath which shields external field. Here we report first evidence that intense boundary emission destroys normal RF sheath and establishes a novel type of RF plasma where external bias is consumed by bulk plasma instead of sheath. Ions are naturally confined while plasma electrons are unobstructed, generating strong RF current in entire plasma, combined with unique particle and energy balance. Proposed model offers possibility for ion erosion mitigation of plasma-facing component. It also inspires technics for reaction rate control in plasma processing and wave mode conversion.

description: Background: Although lichen planus (LP) is a common skin disorder, the prevalence of esophageal involvement (ELP) and its clinical manifestations are poorly defined. We aimed to establish diagnostic criteria and characterize disease outcomes of ELP. Methods: Clinical, endoscopic, histological, and immunofluorescence data from consecutive patients with known LP between 2013 and 2018 were analyzed. We established endoscopic (denudation and tearing of the mucosa, hyperkeratosis and trachealization) and histological criteria (mucosal detachment, T-lymphocytic infiltrate, intraepithelial apoptosis, dyskeratosis, and fibrinogen deposits along the basement membrane) to grade disease severity. Endoscopic findings were correlated with clinical symptoms. Response to medical therapy was monitored. Results: Fifty-two consecutive patients (median age 59.5 years) were analyzed. According to our grading system, 16 patients were considered as severe and 18 as mild ELP. Dysphagia was the only symptom which differentiated patients with severe (14/16) or mild ELP (8/18) from patients without ELP (1/18). Concomitant oral and genital involvement of LP was associated with the presence of ELP, while oral involvement alone was not. Follow-up of 14/16 patients with severe EPL for at least one year revealed that most of these patients responded to topical corticosteroids (budesonide: n = 9/10 or fluticasone n = 2/2). Three budesonide patients experienced a resolution of symptomatic esophageal stenosis. Conclusions: Esophageal involvement of LP is frequent, but may be asymptomatic. ELP can be diagnosed using the diagnostic criteria proposed here. Dysphagia and combined oral and genital manifestation are associated with ELP. Therapy with topical corticosteroids appears to be a prudent therapeutic approach for ELP.

description: Usually, the measurements of electronic and magnetic properties of superconducting samples are carried out under a constant temperature bath. On the other hand, thermal gradients induce local variation of the superconducting order parameter, and the vortex dynamics can present interesting behaviors. In this work, we solved the time-dependent Ginzburg-Landau equations simulating samples under two different thermal gradients, and considering two values of the Ginzburg-Landau parameter, \k{appa}. We find out that both parameters, i.e., \k{appa} and thermal gradients, play an important role on the vortex dynamics and on the magnetization behavior of the samples.

description: This paper presents \textsc{hankel}, a pure-python code for solving Hankel-type integrals and transforms. Such transforms are common in the physical sciences, especially appearing as the radial solution to angularly symmetric Fourier Transforms in arbitrary dimensions. The code harnesses the advantages of solving such transforms via the one-dimensional Hankel transform -- an increase in conceptual simplicity and efficiency -- and implements them in the user-friendly and flexible Python language. We discuss several limitations of the adopted method, and point to the code's extensive documentation for further examples.

description: Abstract: Background: For many disease areas, there are often treatments in different stages of the development process. We consider the design of a two-arm parallel group trial where it is planned to add a new experimental treatment arm during the trial. This could potentially save money, patients, time and resources; however, the addition of a treatment arm creates a multiple comparison problem. Current practice in trials when a new treatment arm has been added is to compare the new treatment only to controls randomised concurrently, and this is the setting we consider here. Furthermore, for standard multi-arm trials, optimal allocation randomises a larger number of patients to the control arm than to each experimental treatment arm. Methods: In this paper we propose an adaptive design, the aim of which is to adapt the sample size of the trial when the new treatment arm is added to control the family-wise error rate (FWER) in the strong sense, whilst maintaining the marginal power of each treatment-to-control comparison at the level of the original study. We explore optimal allocation for designs where a treatment arm is added with the aim of increasing the overall power of the study, where we define the overall power to be the probability of detecting all treatments that are better than the control. Results and conclusions: An increase in sample size is required to maintain the marginal power for each pairwise comparison when adding a treatment arm if control of the FWER is required at the level of the type I error in the original study. When control of the FWER is required in a single trial which adds an additional experimental treatment arm, but control of the FWER is not required in separate trials, depending on the design characteristics, it may be better to run a separate trial for each experimental treatment, in terms of the number of patients required. An increase in overall power can be achieved when optimal allocation is used once a treatment arm has been added to the trial, rather than continuing with equal allocation to all treatment arms.

One historical and three implied volatility estimators were employed. The live cattle sample period was October 31 , 1984 through September 30, 1988. The feeder cattle sample period was January 4, 1988 through September 30, 1988. One observation per day was collected for all put and call contracts and all strike prices. Contemporaneous futures prices were collected to match the put and call observation~ Black ' s European model was as accurate in predicting premiums as Barone-Adesi and Whaley ' s American model across all volatility estimates and opt ion contracts. Implied volatility estimates generated substantially more accurate forecasts of actual option premia than historical volatility. Small differences were found in the predictive ability among the three implied volatility estimates . The significance and signs of the coefficients and explanatory power of the bias regressions were generally consistent across both option pricing models , suggesting that little difference in biases existed between the American and European model. Generally, fewer coefficients were significant in the implied volatility equations compared to the historical volatility equations. In addition, the magnitude of bias associated with variables in the implied volatility equations was substantially less than that of variables in historical volatility equations. Finally, it was found that none of the variables input into the option pricing models (time-to-maturity , moneyness , volatility, and the riskless interest rate) displayed consistent, significant coefficients across markets and option type.

description: Recent time-dependent CP asymmetry measurements in the $B_d \to J/ψK_S$ channel by the BaBar and Belle Collaborations yield somewhat lower values of $\sin 2β$ compared to the one obtained from the standard model fit. If the inconsistency between these numbers persists with more statistics, this will signal new physics contaminating the $B_d \to J/ψK_S$ channel, thus disturbing the extraction of $β$. We show that the R-parity-violating interactions in supersymmetric theories can provide extra new phases which play a role in significantly reducing the above CP asymmetry, thus explaining why BaBar and Belle report lower values of $\sin 2β$. The same couplings also affect the $B_d \to ϕK_S$ decay rate and asymmetry, explain the $B \to η' K$ anomaly, and predict nonzero CP asymmetry in dominant $B_s$ decays. The scenario will be tested in the ongoing and upcoming B factories.

Dengue
Biomarker
C-reactive protein
Prognosis
Other febrile illness

description: Abstract: Background: Dengue infection can cause a wide spectrum of clinical outcomes. The severe clinical manifestations occur sufficiently late in the disease course, during day 4–6 of illness, to allow a window of opportunity for risk stratification. Markers of inflammation may be useful biomarkers. We investigated the value of C-reactive protein (CRP) measured early on illness days 1–3 to predict dengue disease outcome and the difference in CRP levels between dengue and other febrile illnesses (OFI). Method: We performed a nested case-control study using the clinical data and samples collected from the IDAMS-consortium multi-country study. This was a prospective multi-center observational study that enrolled almost 8000 participants presenting with a dengue-like illness to outpatient facilities in 8 countries across Asia and Latin America. Predefined severity definitions of severe and intermediate dengue were used as the primary outcomes. A total of 281 cases with severe/intermediate dengue were compared to 836 uncomplicated dengue patients as controls (ratio 1:3), and also 394 patients with OFI. Results: In patients with confirmed dengue, median (interquartile range) of CRP level within the first 3 days was 30.2 mg/L (12.4–61.2 mg/L) (uncomplicated dengue, 28.6 (10.5–58.9); severe or intermediate dengue, 34.0 (17.4–71.8)). Higher CRP levels in the first 3 days of illness were associated with a higher risk of severe or intermediate outcome (OR 1.17, 95% CI 1.07–1.29), especially in children. Higher CRP levels, exceeding 30 mg/L, also associated with hospitalization (OR 1.37, 95% CI 1.14–1.64) and longer fever clearance time (HR 0.84, 95% CI 0.76–0.93), especially in adults. CRP levels in patients with dengue were higher than patients with potential viral infection but lower than patients with potential bacterial infection, resulting in a quadratic association between dengue diagnosis and CRP, with levels of approximately 30 mg/L associated with the highest risk of having dengue. CRP had a positive correlation with total white cell count and neutrophils and negative correlation with lymphocytes, but did not correlate with liver transaminases, albumin, or platelet nadir. Conclusions: In summary, CRP measured in the first 3 days of illness could be a useful biomarker for early dengue risk prediction and may assist differentiating dengue from other febrile illnesses.

Equivalence classes of non-local unitary operations

description: We study when a multipartite non--local unitary operation can deterministically or probabilistically simulate another one when local operations of a certain kind -in some cases including also classical communication- are allowed. In the case of probabilistic simulation and allowing for arbitrary local operations, we provide necessary and sufficient conditions for the simulation to be possible. Deterministic and probabilistic interconversion under certain kinds of local operations are used to define equivalence relations between gates. In the probabilistic, bipartite case this induces a finite number of classes. In multiqubit systems, however, two unitary operations typically cannot simulate each other with non-zero probability of success. We also show which kind of entanglement can be created by a given non--local unitary operation and generalize our results to arbitrary operators.

description: Precision measurements of charged cosmic rays have recently been carried out by space-born (e.g. AMS-02), or ground experiments (e.g. HESS). These measured data are important for the studies of astro-physical phenomena, including supernova remnants, cosmic ray propagation, solar physics and dark matter. Those scenarios usually contain a number of free parameters that need to be adjusted by observed data. Some techniques, such as Markov Chain Monte Carlo and MultiNest, are developed in order to solve the above problem. However, it is usually required a computing farm to apply those tools. In this paper, a genetic algorithm for finding the optimum parameters for cosmic ray injection and propagation is presented. We find that this algorithm gives us the same best fit results as the Markov Chain Monte Carlo but consuming less computing power by nearly 2 orders of magnitudes.

description: Abstract: We construct several examples of compactifications of Einstein metrics. We show that the Eguchi–Hanson instanton admits a projective compactification which is non-metric, and that a metric cone over any (pseudo)-Riemannian manifolds admits a metric projective compactification. We construct a para-c-projective compactification of neutral signature Einstein metrics canonically defined on certain rank-n affine bundles M over n-dimensional manifolds endowed with projective structures.

description: ABSTRACT

Community involvement is widely recognized as a critical factor in the success and sustainability of development projects. In the context of Mogadishu, Somalia, where international non- governmental organizations (NGOs) play a vital role in addressing socio-economic challenges, understanding the dynamics of community engagement is essential. This study examines the influence of community involvement on the implementation and success ofNGO-funded projects in Mogadishu. Utilizing a mixed-methods approach, the research draws from a sample of 80 respondents, including community leaders, project beneficiaries, project managers, and religious leaders. Keyfindings indicate a high level of awareness and positive perception of NGO projects, with 90% of respondents having participated in such initiatives and 68.8% involved in the decision-making process.

The study reveals that deepening community engagement through participatory planning, continuous feedbackmechanisms, and capacity-building initiatives significantly enhances project outcomes. However, limitations such as the sample size, self-reported data, and the geographic focus on Mogadishu suggest the need for broader and more detailed future research. Recommendations emphasize the importance of inclusive engagement strategies, targeted outreach to underrepresented groups, transparent reporting, and sustainable practices. Additionally, thestudy highlights the need for comprehensive awareness and education strategies to bridge knowledge gaps and foster stronger community support. Future work should focus on expanding sample diversity, incorporating qualitative methods, conducting longitudinal and comparative studies, and exploring the impact of external factors on project implementation. By addressing these areas, NGOs can transform community participation from a nominal role into a meaningful and impactful collaboration, ultimately enhancing the effectiveness andsustainability of their projects. This research underscores the critical role of community involvement in achievingsuccessful NGO interventions and offers valuable insights for improving practices in similar contexts.
