description: Influence of reinforcing FRP elements on the soft clays is investigated. Fiberglass helical pile was designed and produced by Composite Group LLC. Pile is made with pultruded fiber reinforced polymer pipe and cast ironscrew what increases life period due to corrosion absence. This type of micro pile is lighter compared to steel screw piles. Scale laboratory tests were performed imitating vertical elements installed at soft water saturated clays. Reduction of the weak clays’ settlements due to implemented reinforcing elements is described. Results of performed laboratory tests are provided.Experiments have shown that after 30 days vertical reinforcing bars reduce the deformations. Also reinforcement reduces the speed of foundation settlements grow during first two days due to long term consolidation.

description: Global minimum potential energy state can be very challenging to locate in a relatively large atomistic system. Our present work investigates this problem using an example of gold nanoclusters, Au10, Au20, Au30, Au50. Nanoscale gold particles (NGPs) contribute heavily life sciences through their applications in diagnostics and therapeutics. NGPs feature manifold atomistic configurations depending on the conditions of synthesis. We apply annealing molecular dynamics (AMD) as an alternative and supplement to the well-established eigenfollowing (EF) geometry optimization. We conclude that the combination of AMD and EF systematically works more efficiently than EF alone.

description: The CMB temperature-redshift relation, T_CMB(z)=T_0(1+z), is a key prediction of the standard cosmology, but is violated in many non standard models. Constraining possible deviations to this law is an effective way to test the LambdaCDM paradigm and to search for hints of new physics. We have determined T_CMB(z), with a precision up to 3%, for a subsample (104 clusters) of the Planck SZ cluster catalog, at redshift in the range 0.01-- 0.94, using measurements of the spectrum of the Sunyaev Zel'dovich effect obtained from Planck temperature maps at frequencies from 70 to 353 GHz. The method adopted to provide individual determinations of T_CMB(z) at cluster redshift relies on the use of SZ intensity change, Delta I_SZ(nu), at different frequencies, and on a Monte-Carlo Markov Chain approach. By applying this method to the sample of 104 clusters, we limit possible deviations of the form T_CMB(z)=T_0(1+z)^(1-beta) to be beta= 0.022 +/- 0.018, at 1 sigma uncertainty, consistent with the prediction of the standard model. Combining these measurements with previously published results we get beta=0.016+/-0.012.

Year: 2022

description: Abstract
Introduction / Rationale: 
Increasingly, play as an occupation for children takes place in digital spaces. Digital play, mediated by technology such as computers, tablets and dedicated games consoles offers children opportunities for individual and collective play.  Although digital play attracts polarised opinion in social discourse, there remains a paucity of research focussed on its occupational dimensions.
Objectives: 
This scoping review explores the dimension of digital play as an occupation for children.  A review of the existing literature will outline existing evidence of the form, function and meaning as dimensions of digital play. Furthermore, the health and well-being implications of participating in digital play will be mapped as well as its contribution to children's emergent identity and becoming.
Method / Approach:
The six-stage methodology framework by Arksey and O'Malley guided this scoping review design.  Two authors independently reviewed literature identified from automated and manual searches of online databases, reference lists and specific journals.  Selected literature matched pre-determined eligibility criteria and underwent content analysis based on the study objectives.
Results and or Practice Implications:
Increased understanding of the occupational characteristics of digital play will inform a continued examination as to how participation for children can support health and wellbeing.  Extending the dialogue regarding play in digital spaces as occupation will support stakeholders such as game designers to further understand the affordances that support the choices available to children and young people.
Conclusion:
The findings of this scoping review will inform further studies examining expressions of play as occupation in digital spaces.

description: The deliverable is the result of the work carried out in Task 4.1 “5G Exposure Capabilities for Vertical Applications Development” and it also touches Tasks T4.2-T4.5 (Network Applications’ development tasks). As such, key contribution of the deliverable is the description of the work that has been performed during the second period of the project, towards the definition and updated design of the northbound APIs and the exploration of additional APIs that could hold significance and relevance throughout the lifecycle of the Network Applications (Network Apps). An important aspect defined in the project is the integration activities with the main goal of demonstrating the functionality of the Network App when seamlessly integrated with the Vertical Application (vApp) and testing each use case overall. Therefore, integration tests were planned and executed for the EVOLVED-5G Network Apps and their related vApps. These integration efforts utilized the final version of the components developed in EVOLVED-5G and ensured a holistic approach and coherent collaboration between Network Apps and vApps, providing a comprehensive and robust solution for various use cases within the EVOLVED-5G ecosystem. As a final point, in the context of EVOLVED-5G, it is essential to highlight that a terminology update has been implemented. Specifically, the term "Network App" is now being used instead of "NetApp," as initially selected in the first period of the project. This update reflects the shortened form of "Network Application” and has been applied consistently across all project’s documents and materials.

Age dating α-element enhanced stars using asteroseismology

Year: 2024

description: The formation of the Milky Way's stellar halo is believed to have occurred via the accretion of smaller dwarf galaxies, yet the precise timing of these events remains uncertain. A promising avenue to age-date these merger events relies on combining spectroscopic and asteroseismic data of some of the old, metal-poor stars associated with the progenitor galaxies to determine stellar ages using both isochrone fitting and asteroseismology. An important complication in this technique arises due to the fact that old metal-poor stars are overabundant in α elements. Often these stars are modeled using an ad hoc correction to the total metallicity of the stellar models, which allows models to fit the position of stars in the HR diagram. With seismic data of nearby stars now available from Kepler and TESS, we are now in a position to more precisely determine the properties of these α-enhanced stars. We show that implementing the correct treatment of α enhancement decreases the inferred asteroseismic age, based on a seismic reanalysis of the naked-eye star ν Indi using updated mode frequencies from combined TESS observations at 120-second and 20-second cadence. We also investigate how other modeling choices, such as extra mixing at convective boundaries, alters the asteroseismic modeling results.

description: Flexible solidarity is presented by the Commission in the New Pact on Migration and Asylum as a solution to break the deadlock in the reform of the EU asylum policy. The aim of this Article is to analyse to what extent the development of flexible solidarity in the field of asylum will allow the EU to address the shortcomings that the CEAS is facing today. The key question is whether differentiation as regards solidarity serves to further develop the EU asylum policy by introducing a useful degree of flexibility to accommodate the different interests of the Member States or the multiplication of forms of solidarity will lead in the long run to more disintegration. It will also be assessed to what extent the gradual approach followed by the French Presidency of the Council in the first semester of 2022 will allow to make concrete progress on the New Pact on Migration and Asylum and achieve the ambition of a comprehensive asylum and migration policy at EU level in the future.
The Next Frontier for Social Development: Deepening Our Understanding, Discovering New Solutions, and Forging Ahead
Creators: name: Chowa, Gina
Publisher: name: Springer Nature
Year: 2019

description: The field of social development is a relative newcomer to the social welfare arena, emerging out of widespread interest sparked by a series of UN-led meetings during the 1990s that eventually led to the eight Millennium Development Goals. Those concerned with social welfare often bandy about the term social development, confident that everyone has a uniform understanding of the meaning. However, similar to other terms in social welfare such as social justice, and even social welfare, varying and nuanced definitions exist. As a result, discussions can be clouded because of differing interpretations and understandings. Midgley (1995) decisively advanced the field by providing perhaps the first comprehensive yet concise definition of social development: BA process of planned social change designed to promote the well-being of the population as a whole in conjunction with a dynamic process of economic development^ (p. 25). Using Midgley’s foundation, many scholars have proposed models of social development that most often envision the process as ascending stages like the rungs of a ladder (Homfeldt and Reutlinger 2008). However, the process is rarely that simple or linear, and typically requires a multifaceted approach with the capacity to operate simultaneously on several fronts. Thus, the definition of social development has evolved, with the UN defining social development as referring to the promotion of individual well-being that involves the use of a social perspective to consider issues of human activity (UN report 2002). Further, Midgley (2014) has elaborated on his definition by explaining that for social development to occur, economic and social progress must reach harmony in the following three areas: the creation of institutionalized, conjoint formal social and economic policies; economic investments that create opportunities for employment or self-employment; and policies and programs that generate and sustain human capital, including investments in education, housing, and services for maternal and child welfare.

description: The study examines school data and their association with participation in the Wabash County Promise Scholarships program, which combines Children's Savings Accounts (CSAs) with scholarships. CSAs are interventions designed to build educational assets for school age children. Policy makers are increasingly turning to CSAs as a way to augment efforts for improving children's educational outcomes. Findings from this study provide some evidence that having a CSA combined with a scholarship is associated with higher math and reading scores. Findings are strongest among the subsample receiving free/reduced lunch. Further, findings suggest that being a saver (i.e., having at least one family or champion contribution) in Promise Scholars is associated with higher math scores but not reading scores. Finally, evidence suggests that CSAs combined with scholarships in the Promise Scholars program are more closely associated with children's math and reading scores than only CSAs.

description: The use of Permanent Structured Cooperation (PESCO) by the European Union to manage defence cooperation between its Member States is the most recent example of Differentiated Integration (DI) in the EU. Yet differentiation may come at a price. The main aim of the present Article is to assess to what extent defence cooperation under the umbrella of PESCO can be cut up in pieces and yet still be considered a common defence adhering to the EU's general principles of consistency and sincere cooperation. The question, therefore, is whether DI in PESCO is limited by these principles, and consequently, whether the CSDP, despite the differentiation, still contributes to a common policy. In short, the question is whether there is a tension between commonness and differentiation in EU security cooperation.

description: A $(3+1)$-dimensional asymptotically flat Kerr black hole angular speed $Ω_+$ can be used to define an effective spring constant, $k=mΩ_+^2$. Its maximum value is the Schwarzschild surface gravity, $k = κ$, which rapidly weakens as the black hole spins down and the temperature increases. The Hawking temperature is expressed in terms of the spring constant: $2πT = κ- k$. Hooke's law, in the extremal limit, provides the force $F = 1/4$, which is consistent with the conjecture of maximum force in general relativity.

description: Weak G-band stars, or carbon-deficient red giants (CDGs), are a rare class of chemically peculiar G and K giants with carbon abundances that are under-abundant by about a factor of 20 when compared to that of the normal giants. Despite their discovery nearly 70 years ago, the origin of carbon deficiency remains a puzzle. We aimed to better characterize the CDGs by using asteroseismology (Kepler, TESS), spectroscopy (APOGEE, LAMOST), and astrometry (Gaia). We identified 15 new CDGs in the Kepler field and, for the first time, unambiguously identified their evolutionary state as being in the red-clump phase. Our findings reveal that CDGs are primarily low-mass stars (M ≤ 2.0 M⊙), unlike previous suggestions of them being intermediate-mass stars (2.5−5.0 M⊙) based on the HR diagram. The demarcations in chemical patterns and luminosities led us to categorize them into three groups. We concluded that a merger of a helium white dwarf with a red-giant branch star is the most likely scenario for the two groups of over-luminous stars. For the normal-luminosity CDGs, we could not distinguish between core He-flash pollution or lower-mass merger scenarios. The strong correlation between CDGs and Li-rich giants suggests a potential link between their formation processes.

description: The objective of this deliverable is to present in detail the final prototypes and the two integration rounds that have been followed for each of the four Network Applications by the three SMEs participating in the task. Initially, the deliverable describes in detail the final prototypes of the Network Apps developed within pillar of Efficiency in Factory of the Future Operations (FoF) in the EVOLVED-5G context, driven by Task 4.3: NetMapper Network Application by CAF, Anomaly Detection Network App by ZORT, Industrial grade 5G connectivity Network App by ININ, and finally Smart irrigation Network App by UMA/CSIC. Next, the two cycles of integration activities and use case testing that have been followed for each of the three Network Applications, are described. The first round of integrations has been carried out with the aim of ensuring seamless and reliable communication between various components within the system, including Network Apps, Vertical Apps (vApp), NEF, CAPIF and 5G network connectivity, on top of the cloud infrastructure provided by the Athens and Malaga platforms. The connectivity of 5G with the cloud infrastructure has been verified, specifically the connection between vApps and the 5G network. The purpose of the second integration round was to validate the use-cases utilizing the final components of EVOLVED-5G. On the one hand, NEF, CAPIF and the SDK had been enriched with additional features. On the other hand, SMEs finalized their Network Apps by enhancing the 3.0 version and using the last versions of NEF, CAPIF and SDK. This version 4.1 of the Network Apps also exploited the validation pipeline before the integration test. Finally, the Networks Apps were deployed in Kubernetes clusters in Athens NCSRD and Malaga UMA premises instead of using Docker containers running locally. With the second round of integration tests, the Networks Apps of the pillar have reached their final stage, interacting with the last versions of NEF and CAPIF through the SDK and communicating with their respective vApp(s). The three SME use-cases have also been validated and such results highlight the fact that the Network Apps reached a mature enough state to be used by other SMEs through the Evolved- 5G Marketplace

description: Data on key measures of socioeconomic development can be a powerful tool to assist government policies decisions. However, reliable data on such measures at the local level is still lacking in many parts of the world, especially in developing countries. This mainly occurs due to the difficulties of scaling up traditional data collection efforts, such as government surveys, which can be expensive, time-consuming, and overlook hard-to-reach areas.

 In the Brazilian context, the main census institute is known as IBGE (Brazilian Institute of Geography and Statistics) and the data collection is done usually at 10-year intervals. This periodicity produces a data gap that prejudices the interpretability of the collection results, since they may not reflect the Brazilian reality in real-time. The goal of this project is to develop an inexpensive and scalable deep learning method for estimating socioeconomic indicators to fill this data gap using satellite imagery. This is very promising due to the low consumption of resources and the great availability of satellite images, allowing to cover larger and more remote areas and making the process automated and more efficient, without the necessity of on-site collection.

 To this end, the project aims to replicate the work done by Yeh et al. (2020) [1] in the Brazilian scenario, more specifically, the region Vale do Ribeira will be used as a case study. Yeh et al. uses deep neural networks to predict socioeconomic criteria in African countries, based on satellite images of their territories.

Design of a 10 MeV normal conducting CW proton linac based on equidistant multi-gap CH cavities

Year: 2014

description: The continue wave (CW) high current proton linac has wide applications as the front end of the high power proton machines. The low energy part is the most difficult one and there is no widely accepted solution yet. Based on the analysis of the focusing properties of the CW low energy proton linac, a 10 MeV low energy normal conducting proton linac based on equidistant seven-gap Cross-bar H-type (CH) cavities is proposed. The linac is composed of ten 7-gap CH cavities and the transverse focusing is maintained by the quadrupole doublets located between cavities. The total length of the linac is less than 6 meters and the average acceleration gradient is about 1.2 MeV/m. The electromagnetic properties of the cavities are investigated by Microwave Studio. At the nominal acceleration gradient the maximum surface electric field in the cavities is less than 1.3 times Kilpatrick limit, and the Ohmic loss of each cavity is less than 35 kW. The multi-particle beam dynamics simulations are performed with the help of the Tracewin code, the results show that the beam dynamics of the linac is quite stable, and the linac has the capability to accelerate up to 30 mA beam with acceptable dynamics behavior.

description: Many parasites with complex life cycles modify their intermediate hosts' behaviour, presumably to increase transmission to their final host. The threespine stickleback (Gasterosteus aculeatus) is an intermediate host in the cestode Schistocephalus solidus life cycle, which ends in an avian host, and shows increased risky behaviours when infected. We studied brain gene expression profiles of sticklebacks infected with S. solidus to determine the proximal causes of these behavioural alterations. We show that infected fish have altered expression levels in genes involved in the inositol pathway. We thus tested the functional implication of this pathway and successfully rescued normal behaviours in infected sticklebacks using lithium exposure. We also show that exposed but uninfected fish have a distinct gene expression profile from both infected fish and control individuals, allowing us to separate gene activity related to parasite exposure from consequences of a successful infection. Finally, we find that Selective Serotonin Reuptake Inhibitor-treated sticklebacks and infected fish do not have similarly altered gene expression, despite their comparable behaviours, suggesting that the serotonin pathway is probably not the main driver of phenotypic changes in infected sticklebacks. Taken together, our results allow us to predict that if S. solidus directly manipulates its host, it could target the inositol pathway.

The trend of prices and price ratio in Bulgarian beef production are studied as well as the leading factors determining the level and dynamics of procurement prices for the period 2008-2016, using economic-statistical analytical methods and models: the assessment of the price and income elasticity by applying the model by Workman, King, Hooper; cointegration model is applied for determining correlation between the beef wholesale and retail prices on one hand and on another hand the correlation between procurement and retail prices. The descriptive decomposition of the price determination and price manifestation is conducted. Conclusion about the main price features of Bulgarian beef market are presented and their key factors, as well as proposals for solving the adverse effects.

description: High fidelity quantum information transport is necessary for most practical models of quantum computation. By analogy with optical wave guides, a spatio-temporally varying magnetic potential on a one dimensional spin chain can achieve high fidelity transport of spin excitations. By comparing different potential shapes, we establish the effects of potential shape on the fidelity and transport speed. We incorporate disorder into our model and show methods to minimise its effect on transport. Finally, we discuss implementations of our scheme in several accessible systems based on hydrogenic approximations.

description: OBJECTIVE: Depression is a serious mental health disorder, and untangling its causal agents is a major public health priority in the United States. This study examines the relationship between participating in welfare programs during childhood and experiencing depression during young adulthood. METHOD: This study used wave I and IV data from the Add Health (Nâ€¯=â€¯15,701). Multiple imputation is used to deal with missing data. Propensity score matching is used to reduce the selection bias, and then multiple regressions were used to examine the welfare participation and depression relationships. RESULTS: Overall, young adults from welfare-recipient families reported significantly higher depression scores, rather than the clinical diagnosis of depression. Subgroup analyses showed only the poor group had significantly higher depression scores, whereas only the near-poor group had a significantly diagnosed depression outcome. Additionally, significantly higher depression scores were found for female youth from welfare-recipient families. However, no significant differences were found between the gender groups regarding diagnosed depression. DISCUSSION: Using welfare participation as an economic marker, the subgroup analyses help to identify target populations for future intervention. Implications of this study will be of interest to policy makers and have value for informing policy decisions.

The main source of difficulties is the fact that there is no natural group action generating this classification. We establish a number of results on higher order equations which are similar but not completely parallel to the known results on local (holomorphic and meromorphic) gauge equivalence of systems of first order equations.
Play occupations in online games: transactional perspectives of children's play in virtual worlds
Creators: name: Loudoun, Fiona
Publisher: name: Zenodo
Year: 2022

description: The emergence of online games are challenging traditional conceptualisations of play as an occupation.  The increasingly social, yet distributed nature of multi-player games such as Among Us™, Minecraft™ and Fortnite™ offer the potential for children to play within shared virtual spaces using devices with other children connected across a network (Mustola et al., 2018).
This varied nature represents a complex interplay between a child, other children, real and virtual objects within a shared online space. As many games may be considered to represent the world in which the game occurs, play involves a dynamic process of meaning making and interpretation as children engage in different elements of the game.  Online games are evolving, therefore further analysis is required to explore the occupational perspective of the situated and transactive nature of play.
Drawing upon Digital Ethnography and informed by a transactional view of occupation, this research explores the collected narratives of young children's (aged 9 – 11) perspectives and experiences playing the same online game together (Cutchin & Dickie, 2012).
Analysis of children's narratives offers perspectives on children's playing together and how they individually and collectively construct and interpret meaning in online spaces.  It explores the dualism of online play as simultaneously singular and collective.
This study contributes to furthering the understanding of play as an occupation within the context of online games and highlights occupational potential offered by the increasing social composition of online games.

Vale do Ribeira

description: Undegraduate thesis presented at the University of São Paulo. Abstract This work has the objective to train a machine learning algorithm, using satellite images and socioeconomic data. To predict socioeconomic indexes in the Vale do Ribeira’s territory. For that, the project was divided into two parts. The first one has the objective of reproducing the reference article Jean, N., et al. 2016, comprehending the used methods aiming it’s a reproduction on national territory. The second one, objectifies the appropriate adjustment to predict Brazilian human development indexes, starting from IBGE’s census data and satellite images of the Brazilian territory, specifically bounded to the Vale do Ribeira’s territory, for being circumscribed on many protected areas. To do so, the processes, charts, and algorithms from the first part will be used. Based on this approach it is expected to study the efficiency and accuracy inside Brazilian territory. All generated results and accuracy about the algorithm will be shared with the scientific community, more specifically the PARSEC project. The group expects to create algorithms of censitary data predictions, scientific divulgation, and worldwide data sharing.

description: BACKGROUND: The intersection of nutrition and HIV underscores the importance of adequate food and a diverse diet. In communities with high prevalence of food insecurity and HIV, there is a substantial co-occurrence of low dietary diversity, undernutrition, and adverse health outcomes. AIM: The aim of this study was to identify correlates of individual dietary diversity (IDD) and its association with health outcomes for people living with HIV (PLHIV) in rural Zambia. METHODS: The study used a cross-sectional design using data from 101 PLHIV. We calculated IDD using a composite score based on dietary diversity, food frequency, and the relative nutritional importance of different food groups. Adherence was measured using the visual analog scale. Psychosocial functioning was measured using the Structural Barriers to Medication-taking Scale and the Perceived Stress Scale. Data were analyzed using linear and logistic regressions. Multiple imputation was conducted to address missing data. RESULTS: Staples were the most commonly consumed food group. Income and household size were negatively associated with IDD scores. Assets were positively associated with IDD scores. Residing in Lundazi and having a poor or fair self-rated health were associated with lower IDD scores. IDD was also associated, albeit not significant, with desirable health outcomes, including adherence and lower levels of perceived barriers to pill taking and stress. CONCLUSIONS: Findings suggest a heterogeneous effect of socioeconomic variables on IDD. Understanding this heterogeneity is important for the design of interventions. Interventions that combine opportunities to generate economic resources with food and nutrition coaching may be appropriate and effective.

description: In this paper we consider the convex hull of a spherically symmetric sample in $R^d$. Our main contributions are some new asymptotic results for the expectation of the number of vertices, number of facets, area and the volume of the convex hull assuming that the marginal distributions are in the Gumbel max-domain of attraction. Further, we briefly discuss two other models assuming that the marginal distributions are regularly varying or $O$-regularly varying.

description: We reinvestigate the pressure dependence of the crystal structure and antiferromagnetic phase transition in MnTe$_2$ by the rigorous and reliable tool of high pressure neutron powder diffraction. First-principles density functional theory calculations are carried out in order to gain microscopic insight. The measured Néel temperature of MnTe$_2$ is found to show unusually large pressure dependence of $12$ K GPa$^{-1}$. This gives rise to large violation of Bloch's rule given by $α=\frac{d\log T_N}{d\log V}=-\frac{10}{3} \approx -3.3$, to a $α$ value of -6.0 $\pm$ 0.1 for MnTe$_2$. The ab-initio calculation of the electronic structure and the magnetic exchange interactions in MnTe$_2$, for the measured crystal structures at different pressures, gives the pressure dependence of the Neél temperature, $α$ to be -5.61, in close agreement with experimental finding. The microscopic origin of this behavior turns to be dictated by the distance dependence of the cation-anion hopping interaction strength.

description: Objectives The objectives of this study were to examine whether food insecurity is associated with sexual risk taking and victimization in young people (aged 16–24); and to investigate whether the relationship of food insecurity with sexual risk taking and victimization is moderated by gender. Methods Cross-sectional data were obtained in 2014 from a sample of Ghanaian adolescents (n = 773) and in 2015 from young South African adults (n = 823). We used multilevel logistic regression given the study’s binary outcome and clustered data. We tested a moderation effect of gender by including an interaction between gender and food insecurity. Results Food insecurity was highly prevalent (72% in Ghana and 83% in South Africa). Food insecurity was significantly associated with unwanted sexual contact among Ghanaian adolescents (OR 1.05, 95% CI 1.02, 1.08) and age-disparate sex among young South African adults (OR 1.03, 95% CI 1.00, 1.06). Results indicated no moderating effect of gender. Conclusions Our findings underscore the importance of food access on young people’s sexual health, regardless of gender. Prevention efforts may be more relevant when integrated with food security interventions that target vulnerable adolescents and young adults, irrespective of gender.

description: This study aims to analyze the current status of food consumption and nutrition intake among those in the socially vulnerable group including low income households. As a result of the analysis, the elderly living alone in the small rural areas should be considered as the first priority for food assistance programs. In order to improve their nutritional status meat, vegetables, milk and eggs must be provided for them. The government food aid programs should be aimed to ensure a sustainable food supply to the nation while striving to build connections to local agricultural industry and food producers in order to enhance access to safe and fresh foods. The food support method should be chosen after comprehensive consideration of various factors including the physical conditions of the recipient and the accessibility to food suppliers.

description: We consider a fully dynamical origin for the masses of weak gauge bosons and heavy quarks of the Standard Model. Electroweak symmetry breaking and the gauge boson masses arise from new strong dynamics, which leads to the appearance of a composite scalar in the spectrum of excitations. In order to generate mass for the Standard Model fermions, we consider extended gauge dynamics, effectively represented by four fermion interactions at presently accessible energies. By systematically treating these interactions, we show that they lead to a large reduction of the mass of the scalar resonance. Therefore, interpreting the scalar as the recently observed 125 GeV state, implies that the mass originating solely from new strong dynamics can be much heavier, {\em {\em i.e.}} of the order of 1 TeV. In addition to reducing the mass of the scalar resonance, we show that the four-fermion interactions allow for contributions to the oblique corrections in agreement with the experimental constraints. The couplings of the scalar resonance with the Standard Model gauge bosons and fermions are evaluated, and found to be compatible with the current LHC results. Additional new resonances are expected to be heavy, with masses of the order of a few TeVs, and hence accessible in future experiments.

description: The objective of this study was to evaluate the impact of Chuma na Uchizi, a livelihood intervention for people living with HIV (PLHIV) in rural Eastern Province, Zambia, on food security. The intervention included cash transfers to purchase income-generating assets, access to a savings account, and life-skills training. The study employed a non-equivalent groups design to compare intervention (n = 50) and control participants (n = 51) who were receiving outpatient care from two comparable health facilities in distinct constituencies in the same geographic area. We collected data before and after implementation of the intervention. Chuma na Uchizi improved access to food. At follow-up, the intervention group reported lower food insecurity scores compared with the control group (Î² = -5.65; 95% CI - 10.85 --0.45). Livelihood programs for PLHIV are practical and may be a promising approach to address food insecurity and its adverse effects.
