description: Vulnerability depends on the exposure and sensitivity levels of a system to a specific pressure, together with the capacity to cope, recover, or adapt to this pressure. We propose the use of well-known tissular techniques to measure the components of vulnerability. Immunohistochemistry and histopathology indicate the health status of living organisms and the environment. Therefore, these techniques should provide the necessary information to determine the vulnerability of an organism. Immunohistochemical analysis uses biomarkers to determine the presence of toxic compounds, reflecting the exposure level of an organism. Histopathological analysis reveals the environmental impact of a given toxin, reflecting the sensitivity level of the organism to said toxin. Here, we propose a strategy to use these techniques to assess the vulnerability of clams from Tecolutla, Veracruz. We developed categories for each vulnerability component using semi-quantitative scales. Briefly, we calculated the exposure level based on the average number of positive immunohistochemical biomarkers among several organs of clams. Then, we compared the prevalence of histological alterations with the exposure level to determine the sensitivity level. Finally, to estimate the recovery capacity, we placed the control group in a clean environment for 40 days. These led us to observe the capacity of the clams to reverse the effects of environmental stress. Clams showed a moderate level of exposure, a low sensitivity level, and an effective recovery capacity. In conclusion, these results indicate that clams have a low level of vulnerability. This proposal has the potential to guide future works assessing the vulnerability of organisms and later include them in the estimation of vulnerability from aquatic bodies.

description: Completely positive trace preserving maps are essential for the formulation of the second law of thermodynamics. The dynamics of quantum systems, correlated with their environments, are in general not described by such maps. We explore how this issue can be fixed by describing the classical analogue of this problem. We consider correlated probability distributions, whose subsequent system dynamics is ill-described by stochastic maps, and prescribe the correct way to describe the dynamics. We use this prescription to discuss the classical version of the second law, valid for correlated probability distributions.

description: We obtain a representation of an inhomogeneous Levy process in a Lie group or a homogeneous space in terms of a drift, a matrix function and a measure function. Because the stochastic continuity is not assumed, our result generalizes the well known Levy-Ito representation for stochastic continuous processes with independent increments in Euclidean spaces and the extension to Lie groups.

description: The use of financial technology (fintech) has the potential to significantly improve the supply chain performance of micro, small, and medium-sized enterprises (MSMEs) in Bangladesh. The financial sector all over the world is changing so rapidly that it is adding so many new things to it. Fintech can be used to automate tasks, improve visibility, and reduce costs, all of which can lead to better supply chain performance.
This paper will explore the potential influence of emerging fintech on MSME's supply chain performance improvement in Bangladesh. The primary goal of this study is to find out factors that affect supply chain performance in MSMEs of Bangladesh. It will begin by providing an overview of fintech and its potential applications in the supply chain. Then, it will discuss the challenges that MSMEs face in Bangladesh and how fintech can help to address these challenges. Finally, it will present a case study of an MSME that has used fintech to improve its supply chain performance.
The study includes 42 people with professionals, tutors, and students related to Supply chain and other professions. The respondents were asked about the importance of improving the supply chain of MSMEs in Bangladesh and tried to understand the factors that affect supply chain performance in MSMEs of Bangladesh by asking them about the study.
The paper concludes that fintech has the potential to significantly improve the supply chain performance of MSMEs in Bangladesh. However, several challenges need to be addressed before fintech can be fully adopted by MSMEs. These challenges include the lack of awareness of fintech, the high cost of fintech solutions, and the lack of skilled workers.
Despite these challenges, the paper argues that fintech is a promising tool for MSMEs in Bangladesh. With the right support, MSMEs can use fintech to improve their supply chain performance and become more competitive in the global market.

description: The intersection of poverty and HIV/AIDS has exacerbated socioeconomic inequalities in Zambia. For example, the downstream consequences of HIV/AIDS are likely to be severe among the poor. Current research has relied on multidimensional indicators of poverty, which encompass various forms of deprivation, including material. Although comprehensive measures help us understand what constitutes poverty and deprivation, their complexity and scope may hinder the development of appropriate and feasible interventions. These limitations prompted us to examine whether material hardship, a more practicable, modifiable aspect of poverty, is associated with medication adherence and perceived stress among people living with HIV (PLHIV) in Zambia. We used cross-sectional data from 101 PLHIV in Lundazi District, Eastern Province. Data were collected using a questionnaire and hospital records. Material hardship was measured using a five-item scale. Perceived stress was measured using the ten-item perceived stress scale. Adherence was a binary variable measured using a visual analog scale and medication possession ratio (MPR) obtained from pharmacy data. We analyzed the data with multivariable linear and logistic regressions using multiply imputed datasets. Results indicated that greater material hardship was significantly associated with MPR non-adherence (odds ratioâ€‰=â€‰0.83) and higher levels of perceived mental distress (Î²â€‰=â€‰0.34). Our findings provide one of the first evidence on the association of material hardship with treatment and mental health outcomes among PLHIV. The findings also draw attention to the importance of economic opportunities for PLHIV and their implications for reducing material hardship and improving adherence and mental health status.

description: Random forests are among the most popular machine learning techniques for prediction problems. When using random forests to predict a quantitative response, an important but often overlooked challenge is the determination of prediction intervals that will contain an unobserved response value with a specified probability. We propose new random forest prediction intervals that are based on the empirical distribution of out-of-bag prediction errors. These intervals can be obtained as a by-product of a single random forest. Under regularity conditions, we prove that the proposed intervals have asymptotically correct coverage rates. Simulation studies and analysis of 60 real datasets are used to compare the finite-sample properties of the proposed intervals with quantile regression forests and recently proposed split conformal intervals. The results indicate that intervals constructed with our proposed method tend to be narrower than those of competing methods while still maintaining marginal coverage rates approximately equal to nominal levels.

description: We develop a quantum mechanical formalism to treat the strong coupling between an electromagnetic mode and a vibrational excitation of an ensemble of organic molecules. By employing a Bloch-Redfield-Wangsness approach, we show that the influence of dephasing-type interactions, i.e., elastic collisions with a background bath of phonons, critically depends on the nature of the bath modes. In particular, for long-range phonons corresponding to a common bath, the dynamics of the "bright state" (the collective superposition of molecular vibrations coupling to the cavity mode) is effectively decoupled from other system eigenstates. For the case of independent baths (or short-range phonons), incoherent energy transfer occurs between the bright state and the uncoupled dark states. However, these processes are suppressed when the Rabi splitting is larger than the frequency range of the bath modes, as achieved in a recent experiment [Shalabney et al., Nat. Commun. 6, 5981 (2015)]. In both cases, the dynamics can thus be described through a single collective oscillator coupled to a photonic mode, making this system an ideal candidate to explore cavity optomechanics at room temperature.

description: Recent research on rural in-migration has mostly been done from an in-migrants' perspective. This paper, however, centers on rural residents' attitudes toward in-migrants from outside. Rural residents' attitudes are important because they can significantly affect the success or failure of in-migrants' settling in rural areas. Analysis is conducted using data from Survey on Rural Living Indicators. Results indicate that key predictors of rural residents' attitudes toward in-migrants are engagement in agriculture, satisfaction with community environment and a sense of community.

The conclusions come from the relationships between the irreducibility of some nonnegative block matrix associated to a multiplex network and the irreducibility of the corresponding matrices to each layer as well as the irreducibility of the adjacency matrix of the projection network. In addition the computation of that Perron vector in terms of the Perron vectors of the blocks is also addressed. Finally we present the precise relations that allow to express the Perron eigenvector of the multiplex network in terms of the Perron eigenvectors of its layers.

description: The worldwide food sector continues to contribute an important part in harming the environment in the form of greenhouse gas emissions, water pollution, and degradation of soil. To overcome these difficulties, transformational strategies are required. This study analyzes the combination of Circular Economy (CE) concepts and Industry 5.0 (I5.0) technologies in order to establish sustainable supply chain management in the food industry. The CE tactics, which strives to reduce waste and enhance the use of resources, can be implemented by adopting efforts such as reducing food waste, utilizing recyclable packaging, and repurposing food waste. I5.0 is defined by cutting-edge technology such as AI and IoT and provides real-time data knowledge, automation, and increased supply chain coordination. This integration is consistent with the food industry's aim of growing environmentally conscious. The study delves into the principles of the circular economy, the advantages of merging CE and I5.0, the challenges of doing so, and effective business situations. Despite hurdles such as a lack of expertise as well as elevated implementation costs, the food sector has an interest in implementing this strategy due to the benefits of reduced environmental impact, improved economic efficiency, and enhanced nutrition. Through a tour of crucial material, we explain how CE and I5.0 could transform the ways food is produced, distributed, and eaten. The research underlines the importance of these principles in assisting the food industry in overcoming its sustainability challenges. Targets in the paper also include talks of environmental sustainability concerns in the food sector, possibilities presented by CE and I5.0 integration, challenges, chances of resolving obstacles, and the groundbreaking influence of company 5.0 on the food company. We find overlaps between CE and I5.0 by reviewing existing research and discussing how they operate together to decrease waste, increase quality, while opening up fresh markets. Furthermore, we emphasize how I5.0's fusion of the digital and physical worlds has facilitated a shift toward human-centric production. In conclusion, this study underscores how vital it is for the food industry to make the transition to sustainability. The integration of Industry 5.0 technologies and Circular Economy principles is one possible future direction. By combining cutting-edge technologies with resource-efficient processes, the food sector can evolve into a more environmentally conscientious and economically viable organization, helping create a more sustainable future.

description: This paper examines the diversification economies and the impact of the degree of crop diversification on the technical efficiency of multi-output production system, using farm-level panel data from the period 2008 to 2012. Measurements are obtained from the estimation of a stochastic multi-output input distance function. This study corrects for sample selection bias in the context of a translog functional form that appears when some farms produce only two outputs. The empirical results indicate that diversification economies are found to exist in the efficient small farms. However, greater diversification lead to lower technical efficiency.

description: An \itbf{indeterminate string} (or, more simply, just a \itbf{string}) $\s{x} = \s{x}[1..n]$ on an alphabet $Σ$ is a sequence of nonempty subsets of $Σ$. We say that $\s{x}[i_1]$ and $\s{x}[i_2]$ \itbf{match} (written $\s{x}[i_1] \match \s{x}[i_2]$) if and only if $\s{x}[i_1] \cap \s{x}[i_2] \ne \emptyset$. A \itbf{feasible array} is an array $\s{y} = \s{y}[1..n]$ of integers such that $\s{y}[1] = n$ and for every $i \in 2..n$, $\s{y}[i] \in 0..n\- i\+ 1$. A \itbf{prefix table} of a string $\s{x}$ is an array $\sπ = \sπ[1..n]$ of integers such that, for every $i \in 1..n$, $\sπ[i] = j$ if and only if $\s{x}[i..i\+ j\- 1]$ is the longest substring at position $i$ of \s{x} that matches a prefix of \s{x}. It is known from \cite{CRSW13} that every feasible array is a prefix table of some indetermintate string. A \itbf{prefix graph} $\mathcal{P} = \mathcal{P}_{\s{y}}$ is a labelled simple graph whose structure is determined by a feasible array \s{y}. In this paper we show, given a feasible array \s{y}, how to use $\mathcal{P}_{\s{y}}$ to construct a lexicographically least indeterminate string on a minimum alphabet whose prefix table $\sπ = \s{y}$.

description: An analytical study is presented of the double resonant Raman scattering process in graphene, responsible for the D and D$^{\prime}$ features in the Raman spectra. This work yields analytical expressions for the D and D$^{\prime}$ integrated Raman intensities that explicitly show the dependencies on laser energy, defect concentration, and electronic lifetime. Good agreement is obtained between the analytical results and experimental measurements on samples with increasing defect concentrations and at various laser excitation energies. The use of Raman spectroscopy to identify the nature of defects is discussed. Comparison between the models for the edge-induced and the disorder-induced D band intensity suggests that edges or grain boundaries can be distinguished from disorder by the different dependence of their Raman intensity on laser excitation energy. Similarly, the type of disorder can potentially be identified not only by the intensity ratio $I_{\mathrm{D}}/I_{\mathrm{D}^{\prime}}$, but also by its laser energy dependence. Also discussed is a quantitative analysis of quantum interference effects of the graphene wavefunctions, which determine the most important phonon wavevectors and scattering processes responsible for the D and D$^{\prime}$ bands.

description: Background Community-based distribution (CBD) of injectable contraceptives has increased access to family planning for millions of women in rural areas in resource-limited settings. Despite the evidence of the success of this contraceptive delivery method, many nations have yet to integrate CBD into their family planning policies. The aim of this paper to describe the process through which PATH spearheaded efforts to successfully advocate for policy change to authorize non-clinical personnel in Zambia to provide injectable contraceptives. Methods We describe a four-part framework for policy advocacy: (a) evidence building and technical assistance, (b) stakeholder engagement, (c) government engagement, and (d) knowledge dissemination. Results Advocacy for policy change to allow CBD of injectable contraceptives was long and iterative. Evidence to support advocacy efforts was built through a Zambian delegates’ study tour to Rwanda to witness Rwanda’s robust CBD program and a rapid assessment of Zambian pilot sites where non-clinical personnel were administering injectable contraceptives. Advocacy was led by PATH in partnership with key stakeholders from the Zambia Family Planning Technical Working Group (FPWTG), key government officials, and a special task force of stakeholders focused on advocating for CBD of injectable contraceptives. This task force used evidence from the study tour and rapid site assessment in national and international forums to demonstrate the beneficial effects of allowing non-clinical personnel to administer injectable contraceptives. The Zambian government authorized the policy change in 2016. Conclusion The policy advocacy efforts of PATH, FPWTG, and the special task force demonstrate the need for an ample evidence base and sustained engagement of government and stakeholder groups.

description: We investigate an open $XYZ$ spin $1/2$ chain driven out of equilibrium by boundary reservoirs targeting different spin orientations, aligned along the principal axes of anisotropy. We show that by tuning local magnetic fields, applied to spins at sites near the boundaries, one can change any nonequilibrium steady state to a fully uncorrelated Gibbsian state at infinite temperature. This phenomenon occurs for strong boundary coupling and on a critical manifold in the space of the fields amplitudes. The structure of this manifold depends on the anisotropy degree of the model and on the parity of the chain size.

These objects, with a similar mass and similar decay modes to $π^0$ mesons, could provide an explanation for the non-asymptotic behavior of the pion-photon transition form factor observed by the Babar Collaboration. No significant signal is observed, and limits on the production cross section at the level of 73 fb or 370 fb, depending on the model parameters, are determined at 90% confidence level. These upper limits lie below the cross section values needed to explain the Babar form factor data.

description: Food insecurity heightens risk for poor mental health and psychosocial functioning. Higher levels of future orientation influence numerous desirable behaviors. However, limited evidence exists on the association between food insecurity and future orientation, particularly in low-resource settings. The objective of this study was to examine the association between food insecurity and future orientation of Ghanaian youth and their parents. The study included a cross-sectional sample of 2656 youth and 2656 parents from 8 of Ghanaâ€™s 10 regions. Food insecurity was measured using the Household Food Insecurity Access Scale. Future orientation in the Ghanaian context was measured using three distinct factors adapted from the School Success Profile and the Consideration of Future Consequences scale. We analyzed our data using hierarchical linear modeling, with a three-level linear random-intercept model with covariates. Results suggest an inverse relationship between food insecurity and future orientation of youth and their parents. Food insecurity was consistently and significantly associated with lower orientation toward success (Î² = âˆ’0.18, 95% confidence interval [CI] = âˆ’0.22, âˆ’0.14) and higher uncertainty of the future (Î² = 0.22, 95% CI = 0.17, 0.28) among youth, as well as lower consideration of future consequences (Î² = âˆ’0.15, 95% CI = âˆ’0.23, âˆ’0.06) among parents. Additionally, severe food insecurity was associated with the lowest future orientation scores for youth and their parents. Our findings indicate that, under conditions of food insecurity, youth and their parents lose sight of the future, which may come at a great cost. Encouraging individuals to engage in thinking about the future or to create future images of their selves may not be meaningful if their basic needs, including access to food, are not met. Programs that provide opportunities to generate income and accumulate assets may have a twofold effect of increasing access to food and improving future orientation.

description: We perform a post-compression of high energy pulses by using optical-field ionization of low pressure helium gas in a guided geometry. We apply this approach to a TW chirped-pulse-amplification based Ti:Sapphire laser chain and show that spectral broadening can be controlled both with the input pulse energy and gas pressure. Under optimized conditions, we generate 10 fs pulses at TW level directly under vacuum and demonstrate a high stability of the post compressed pulse duration. These high energy post-compressed pulses are thereafter used to perform high harmonic generation in a loose focusing geometry. The XUV beam is characterized both spatially and spectrally on a single shot basis and structured continuous XUV spectra are observed.

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 the EVOLVED-5G project. On the one hand, NEF, CAPIF and the SDK were enriched with additional features, as described in D3.3 and D3.4. 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, until the latest version of the Network Apps was finally developed: 4.1. This version 4.1 of the Network Apps also exploited the validation pipeline before the integration test took place. Finally, the Network Apps were deployed in Kubernetes clusters in Malaga 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: In recent years, transformation of rural industries into high-valued and more complex industries based on agricultural production has been accelerating. The Ministry of Agriculture, Food and Rural Affairs has focused on rural industry development for promoting indigenous local industries, regional agricultural clusters and the food industry. The problems that have surfaced in the rural industry sector are lack of the capitalization effect and the changeover from livelihood-type agriculture to an industrial ecosystem. Thus, measures to build business systems based on endogenous rural vitalization, regional economic growth, and convergence of rural industries are urgently needed. In this situation, this study aims to set up business ecosystems of rural industries based on productivity, robustness and niche creation. Also, we evaluate these factors with 15 agricultural experts using the Analytic Hierarchy Process(AHP). According to the AHP analysis, the niche creation in business ecosystems represents the largest portion at 46.5 percent, followed by the productivity at 31.9 percent and the robustness at 21.5 percent. This study suggests that the basic direction of business ecosystems should be geared toward making them sustainable business by sharing values and saving social capital.

description: To date, 17 circumbinary planets have been discovered. In this paper, we focus our attention on the stability of the Kepler circumbinary planetary systems with only one planet, i.e. Kepler-16, Kepler-34, Kepler-35, Kepler-38, Kepler-64 and Kepler-413. In addition to their intrinsic interest, the study of such systems is an opportunity to test our understanding of planetary system formation and evolution around binaries. The investigation is done by means of numerical simulations. We perform numerical integrations of the full equations of motion of each system with the aim of checking the stability of the planetary orbit. The investigation of the stability of the above systems consists of three numerical experiments. In the first one we perform a long term (1Gyr) numerical integration of the nominal solution of the six Kepler systems under investigation. In the second experiment, we look for the critical semimajor axis of the six planetary orbits, and finally, in the third experiment, we construct two dimensional stability maps on the eccentricity-pericentre distance plane. Additionally, using numerical integrations of the nominal solutions we checked if this solutions were close to the exact resonance.

description: We study a decomposition of a general Markov process in a manifold invariant under a Lie group action into a radial part (transversal to orbits) and an angular part (along an orbit). We show that given a radial path, the conditioned angular part is a nonhomogeneous \levy process in a homogeneous space, we obtain a representation of such processes, and as a consequence, we extend the well known skew-product of Euclidean Brownian motion to a general setting.

A Multilevel Conceptual Framework to Understand the Role of Food Insecurity on Antiretroviral Therapy Adherence in Low-Resource Settings: From Theory to Practice
Creators: name: Chowa, Gina
name: Masa, Rainier
Publisher: name: Taylor & Francis
Year: 2017

description: The objective of this study was to describe a multilevel conceptual framework to understand the role of food insecurity on antiretroviral therapy adherence. The authors illustrated an example of how they used the multilevel framework to develop an intervention for poor people living with HIV in a rural and low-resource community. The framework incorporates intrapersonal, interpersonal, and structural-level theories of understanding and changing health behaviors. The framework recognizes the role of personal, social, and environmental factors on cognition and behavior, with particular attention to ways in which treatment adherence is enabled or prevented by structural conditions, such as food insecurity.
Texture analysis using volume-radius fractal dimension

description: Texture plays an important role in computer vision. It is one of the most important visual attributes used in image analysis, once it provides information about pixel organization at different regions of the image. This paper presents a novel approach for texture characterization, based on complexity analysis. The proposed approach expands the idea of the Mass-radius fractal dimension, a method originally developed for shape analysis, to a set of coordinates in 3D-space that represents the texture under analysis in a signature able to characterize efficiently different texture classes in terms of complexity. An experiment using images from the Brodatz album illustrates the method performance.

description: DNA nanotubes are tubular structures composed of DNA crossover molecules. We present a bottom up approach for construction and characterization of these structures. Various possible topologies of nanotubes are constructed such as 6-helix, 8-helix and tri-tubes with different sequences and lengths. We have used fully atomistic molecular dynamics simulations to study the structure, stability and elasticity of these structures. Several nanosecond long MD simulations give the microscopic details about DNA nanotubes. Based on the structural analysis of simulation data, we show that 6-helix nanotubes are stable and maintain their tubular structure; while 8-helix nanotubes are flattened to stabilize themselves. We also comment on the sequence dependence and effect of overhangs. These structures are approximately four times more rigid having stretch modulus of ~4000 pN compared to the stretch modulus of 1000 pN of DNA double helix molecule of same length and sequence. The stretch moduli of these nanotubes are also three times larger than those of PX/JX crossover DNA molecules which have stretch modulus in the range of 1500-2000 pN. The calculated persistence length is in the range of few microns which is close to the reported experimental results on certain class of the DNA nanotubes.

description: The high efficiency, low-background, and single-photon detection with transition-edge sensors (TES) is making this type of detector attractive in widely different types of application. In this paper, we present first characterizations of a TES to be used in the Any Light Particle Search (ALPS) experiment searching for new fundamental ultra-light particles. Firstly, we describe the setup and the main components of the ALPS TES detector (TES, millikelvin-cryostat and SQUID read-out) and their performances. Secondly, we explain a dedicated analysis method for single-photon spectroscopy and rejection of non-photon background. Finally, we report on results from extensive background measurements. Considering an event-selection, optimized for a wavelength of $1064~{\rm nm}$, we achieved a background suppression of $\sim 10^{-3}$ with a $\sim 50~\%$ efficiency for photons passing the selection. The resulting overall efficiency was $23~\%$ with a dark count rate of $8.6 \cdot 10^{-3}~{\rm s}^{-1}$. We observed that pile-up events of thermal photons are the main background component.

description: Recently, the world agricultural market has been integrated very fast under free trade agreements. Although this dramatic change may cause disastrous effects on Korean agricultural sector, it could also be a huge change to increase Korean agricultural exports. Pears are considered as one of the most important export items because their export is growing very fast in recent years. This paper examines the structure of Korea's pear export using the gravity equation to draw an implication for policy makers and pear exporters. The important finding is the number of Korean immigrants has been played an important role to pear exports of Korea.
