Association between Disability and Unmet Food Needs in the Venezuelan Migrant and Refugee Population: Analysis of a Population-Based Survey, 2022

In Peru, Venezuelan migrants and refugees have been exposed to food shortages before their emigration. This problem could have worse outcomes in vulnerable populations (such as people with disabilities); however, the literature on the basic needs of this population is still scarce. The objective was to determine the association between the presence of disability and the unmet need for access to food in the household of the Venezuelan migrant and refugee population residing in Peru. A cross-sectional study was conducted using data from the Second Survey of the Venezuelan Population Residing in Peru (ENPOVE 2022). The outcome variable was unmet need for food, while the independent variable was the presence of disability. Poisson log generalized linear regression models (crude and adjusted for potential confounding variables) were fitted to evaluate the association between the variables of interest, reporting prevalence ratios (PR) and 95% confidence intervals (CIs). A total of 7739 migrants and refugees from Venezuela were included. The proportion of unmet need for access to food in the household was 45.2%, while the proportion of disability was 2.1%. People with disabilities were found to be more likely to have an unmet need for access to food at home (adjusted PR [aPR]: 1.25; 95% CI: 1.08–1.46; p = 0.003). According to our findings, almost half of Venezuelan households were found to have an unmet need for access to food. In addition, Venezuelan migrants and refugees with disabilities were more likely to have an unmet need for this basic need.
On the Diurnal Variation of Mountain Waves

Abstract The diurnal variation of mountain waves and wave drag associated with flow past mesoscale ridges has been examined using the Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS) and an analytical boundary layer (BL) model. The wave drag exhibits substantial diurnal variation in response to the change in the atmospheric BL characteristics, such as the BL depth, shape factor, and stability. During daytime, a convective BL develops, characterized by a shallow shear layer near the surface and a deep well-mixed layer aloft, both of which tend to decrease the wave drag. As a result, the convective BL could significantly weaken mountain waves and reduce the momentum flux by up to 90%. Near the surface, the flow pattern resembles a potential flow with a surface wind maximum located near the ridge crest. During nighttime, a shallow stable BL develops, and the modulation of wave drag by the stable nocturnal BL is governed by the BL Froude number (Fr). If the BL flow is supercritical, the drag incr.
An Updated Review on the Role of Nanoformulated Phytochemicals in Colorectal Cancer

The most common cancer-related cause of death worldwide is colorectal cancer. It is initiated with the formation of polyps, which further cause the development of colorectal cancer in multistep phases. Colorectal cancer mortality is high despite recent treatment breakthroughs and a greater understanding of its pathophysiology. Stress is one of the major causes of triggering different cellular signalling cascades inside the body and which might turn toward the development of cancer. Naturally occurring plant compounds or phytochemicals are being studied for medical purposes. Phytochemicals’ benefits are being analyzed for inflammatory illnesses, liver failure, metabolic disorders, neurodegenerative disorders, and nephropathies. Cancer treatment with fewer side effects and better outcomes has been achieved by combining phytochemicals with chemotherapy. Resveratrol, curcumin, and epigallocatechin-3-gallate have been studied for their chemotherapeutic and chemopreventive potentiality, but hydrophobicity, solubility, poor bioavailability, and target selectivity limit the clinical uses of these compounds. The therapeutic potential is maximized by utilizing nanocarriers such as liposomes, micelles, nanoemulsions, and nanoparticles to increase phytochemical bioavailability and target specificity. This updated literature review discusses the clinical limitations, increased sensitivity, chemopreventive and chemotherapeutic effects, and the clinical limitations of the phytochemicals.
Sampling and Interpolation on Some Nilpotent Lie Groups

Let N be a non-commutative, simply connected, connected, two-step nilpotent Lie group with Lie algebra n such that n = a⊕ b⊕ z, [a, b] ⊆ z, the algebras a, b, z are abelian, a = R-span {X1, X2, · · · , Xd} , and b = R-span {Y1, Y2, · · · , Yd} . Also, we assume that det [[Xi, Yj ]]1≤i,j≤d is a non-vanishing homogeneous polynomial in the unknowns Z1, · · · , Zn−2d where {Z1, · · · , Zn−2d} is a basis for the center of the Lie algebra. Using well-known facts from time-frequency analysis, we provide some precise sufficient conditions for the existence of sampling spaces with the interpolation property, with respect to some discrete subset of N . The result obtained in this work can be seen as a direct application of time-frequency analysis to the theory of nilpotent Lie groups. Several explicit examples are computed. This work is a generalization of recent results obtained for the Heisenberg group by Currey, and Mayeli in [3].
Synthesis of Tungsten-Cerium Doped Titanium Oxide Nanocatalyst to Remediate Water by the Degradation of Atrazine Herbicide

Tungsten (W) and Cerium (Ce) doped nanoTitanium oxide (TiO2) nanophotocatalyst were prepared by the sol-gel method and their photodegradation effect against atrazine herbicide were investigated. The doping of the nanocatalyst took place at 50 °C within a time interval of 120 minutes. The prepared gel was dried and calcined in the oven at 350 °C for 75 minutes. The XRD result revealed that the synthesized nanocatalyst was 16.7 nm in size with a mostly monoclinic structure. With FTIR spectra, characteristic peaks of TiO2 were found at 516 cm-1, Ti-O-Ce at 1104 cm-1, and W-O with a single bond at 1609 cm-1. Scanning electron microscope analysis revealed the surface morphology of synthesized nanophotocatalyst. The photocatalytic activity of synthesized nanocatalyst was tested on the degradation of atrazine herbicide (ATZ) under visible and UV light in a batch reactor. The efficiency of nanocatalyst was compared for effective utilization. About 46.5 % of photocatalytic activity was observed without UV light irradiation within 120 minutes. The photocatalytic activity of W-Ce co-doped TiO2 to degrade atrazine further increased up to 99.1 % when the solution was irradiated under UV light. Factors like pH, time, and concentration of nanocatalyst were optimized to check the photocatalytic activity of nanocatalyst on ATZ. It was concluded that nanocatalyst showed an efficient photocatalytic degradation at pH 6 within 120 mins time interval after exposure to UV light.
Low Vitamin K and Vitamin D Dietary Intake in Patients with Inflammatory Bowel Diseases

The inadequate dietary intake of Vitamin D and Vitamin K is an easily reversible factor favoring IBD-associated bone loss, but data on Vitamin K are lacking. A 28-item quantitative food frequency questionnaire was administered to 193 IBD patients (89 Crohn’s disease and 104 ulcerative colitis), and 199 controls. Patients’ demographics, clinical and laboratory findings were analyzed in relation to recommended daily allowances. VitD intake was inadequate both in the IBD and control patients (8.3 ± 4.5 µg/day in IBD, 53.1% RDA, and 9.7 ± 5.9 µg/day, 63.2% RDA, respectively). Conversely, the mean ViK intake was less than adequate in IBD, at 116.7 ± 116.3 µg/day (78.7% RDA), and high in controls, at 203.1 ± 166.9 µg/day (138.8% RDA). Nonetheless, due to marked inter-individual differences, diets were severely lacking VitK in 40% of UC and 49% of CD patients, more so in females and those with active disease. The intake of Vit D was non-significantly lower in colitis than that in Crohn’s disease (7.9 vs. 8.7 µg/day). The opposite was observed for VitK (123.5 vs. 107.0 µg/day). Thus, the diet lacks the micronutrients involved in bone wellbeing in a large proportion of IBD patients. While VitD supplementation is the rule, VitK shortages need proactive nutritional intervention.
Factors Affecting Passengers’ Acceptance of Single Pilot Operations: A Qualitative Study conducted in Greece

Aviation is undeniably one of the fastest-growing industries worldwide (ICAO, 2022). Analysts predict that despite a brief―yet considerable―pause, brought on by COVID-19 (Gao, 2022;IATA, 2022), global aviation traffic is increasing and will possibly threefold in the next 30 years (Gössling & Humpe, 2020;ICAO, 2023). Furthermore, this tremendous increase in air travel will also trigger a considerable need for personnel and will unavoidably lead to a significant shortage of pilots which has been forecasted by many sources in the past (Bennett & Vijaygopal, 2021;Champ, 2022;Meredith, 2019;Moehle & Clauss, 2015;Rice et al., 2014). Specifically, trends showed that the world will be lacking approximately 800,000 pilots by the year 2037 (Caraway, 2020). Put another way, the demand for airline pilots is going to outweigh the supply by far. Unfortunately, the high entry cost of new pilots to the industry and the relatively low salaries are averting a quick fix to this problem (Lutte, 2014) © 2022, International Journal of Aviation, Aeronautics, and Aerospace.All Rights Reserved.
Inspection Digital Literacy for School Improvement

Educational inspection, as an essential part of the current educational environment, supports its mission through more pragmatic and comprehensive processes, techniques, and models, which guarantee the right of students to quality education. The aim of the present study was to determine the causal effect of gender and age on the dimensions of the instrument in the inspector population. Specifically, 118 male and female inspectors from the Educational Inspection Service of Andalusia (Spain) participated, with an average age of 47.56 years (±5.70). In terms of gender, 30 were women (25.40%) and 88 were men (74.60%). An instrument was developed specifically for this study with the purpose of assessing the participants’ opinions of the extent to which their work contributes to educational improvement. The results evidenced the relationship between the dimensions of the instrument: attention to members of the educational community (AMEC), supervision of guidance and tutorial action (SGTA), attention and inclusion of diversity (AID), and technological resources (TR) (p < 0.01). Similarly, the multigroup model obtained good structural validity (χ2 = 68.180; RMSEA = 0.078; GFI = 0.923; CFI = 0.959; IFI = 0.967). In terms of gender, no significant differences were obtained, although the results were moderately superior among males compared to females. In relation to age, younger inspectors had better TR results, and older inspectors had better AMEC and SGTA results. The conclusions strengthen the importance of the Education Inspection Service in educational establishments, highlighting the need to supervise the processes of attention and inclusion for diversity. A great deal of resistance was observed, especially as there is a lack of training in information and communication technology (ICT).
Multiple Forms of Neural Cell Death in the Cyclical Brain Degeneration of A Colonial Chordate

Human neuronal loss occurs through different cellular mechanisms, mainly studied in vitro. Here, we characterized neuronal death in B. schlosseri, a marine colonial tunicate that shares substantial genomic homology with mammals and has a life history in which controlled neurodegeneration happens simultaneously in the brains of adult zooids during a cyclical phase named takeover. Using an ultrastructural and transcriptomic approach, we described neuronal death forms in adult zooids before and during the takeover phase while comparing adult zooids in takeover with their buds where brains are refining their structure. At takeover, we found in neurons clear morphologic signs of apoptosis (i.e., chromatin condensation, lobed nuclei), necrosis (swollen cytoplasm) and autophagy (autophagosomes, autolysosomes and degradative multilamellar bodies). These results were confirmed by transcriptomic analyses that highlighted the specific genes involved in these cell death pathways. Moreover, the presence of tubulovesicular structures in the brain medulla alongside the over-expression of prion disease genes in late cycle suggested a cell-to-cell, prion-like propagation recalling the conformational disorders typical of some human neurodegenerative diseases. We suggest that improved understanding of how neuronal alterations are regulated in the repeated degeneration–regeneration program of B. schlosseri may yield mechanistic insights relevant to the study of human neurodegenerative diseases.
On the first variation of a varifold

Suppose M is a smooth m dimensional Riemannian manifold and k is a positive integer not exceeding m. Our purpose is to study the first variation of the k dimensional area integrand in M. Our main result is a regularity theorem for weakly defined k dimensional surfaces in M whose first variation of area is summable to a power greater than k. A natural domain for any k dimensional parametric integral in M, among which the simplest is the k dimensional area integral, is the space of k dimensional varifolds in M introduced by Almgren in [AF 1]. Such a varifold is defined to be a Radon measure on the bundle over M whose fiber at each point p of M is the Grassmann manifold of k dimensional linear subspaces of the tangent space to M at p. If V is a varifold in M, let I I V I I be the Radon measure on M obtained from V by ignoring the fiber variables. Naturally injected in the space of k dimensional varifolds in M is the set of k dimensional rectifiable subsets of M, which includes the set of k dimensional submanifolds of M as well as more general k dimensional surfaces in M. A k dimensional varifold in M is said to be rectifiable (integral) if it can be strongly approximated by a positive real (integral) linear combination of varifolds corresponding to continuously differentiable k dimensional submanifolds of M. To any classical k dimensional geometric object in M there corresponds a k dimensional integral varifold in M. If N is a smooth Riemannian manifold and F: M-e N is smooth, then F induces in a natural way a strongly continuous mapping F# of the k dimen-
Hausdorff measure, BMO, and analytic functions.

Let W be an open set in the plane, and the class BMO (W) be defined as follows: a measurable function / o n W is BMO if to each ball B contained in W there is a constant c = c(B) so that I \ \f(x, y) — c(B)\dxdy ^ Am(B), with a constant A — A{f). For any complex function / on W, S(f) is the set of points at which / fails to admit a complex derivative; S(f) in general is neither open nor closed, but is in fact a Borel set.
Physical interpretation of induction and frequency dependence of power losses in soft magnetic materials

A loss model based on a dynamic generalization of the Preisach hysteresis model, in which the standard Preisach algorithm is coupled to an equation for the rate of change of the flux associated with each elementary Preisach loop, is presented. The model is able to predict loss features not explained by previous treatments and provides a general interpretative frame for the study of the connection between power losses and microstructure of soft magnetic materials. >
Modeling and Hover Flight Control of a Micromechanical Flapping-Wing Aircraft Inspired by Wing–Tail Interaction

This article intends to give a comprehensive model to a brand new micromechanical flapping-wing aircraft inspired by wing–tail interaction. In this aircraft, the flapping-wing induced flow contributes to the tail control torque generation. However, this also makes the wing–tail interaction nonnegligible, and this flow would be disturbed by the relative flow produced by the body motion. The dominant unsteady aerodynamic effects of the flapping wing are considered. The flapping-wing induced flow over the tail is included when analyzing the tail aerodynamics. Especially, the aerodynamic–dynamic coupling effect of both the wing and the tail is considered to account for the force due to the body motion. A nonlinear and time-periodic simulation model of the aircraft is, thus, established. The model is averaged and linearized around hover status. Because of the combination of the wing–tail interaction with the aerodynamic–dynamic coupling, the state and control matrixes, including both the induced flow effect and the body motion effect, can be obtained. The pitch dynamics are analyzed, and it is found that the tail can push the two unstable oscillatory poles closer to the imaginary axis. The role of the tail is fully demonstrated by considering the induced flow. Cascade controllers are also designed according to the root-locus plot based on the built model. Due to the inclusion of the wing–tail interaction and the aerodynamic–dynamic coupling, the controllers are proved to be efficient in the attitude stabilization during statistic hover, descent, and ascent flights. Our proposed model can be easily applied to the modeling of other flapping-wing aircraft with similar structures, and it makes the controller design process more efficient and targeted.
Expanding understanding of brand value co-creation on social media from an S-D logic perspective: Introducing structuration theory

Brands are increasingly seen in light of collaborative, value creation activities of a firm and all of its stakeholders. This is strongly influenced by the emergence and dominant role that social media plays in societies globally. With challenges presented for brand management and marketing scholarship more generally, to understand and react to the social implications presented for brand value creation. Accordingly, this study builds on the principles of S-D logic to expand understanding of the co-creation of brand value on social media. We introduce social construction theories, focusing on structuration theory. A conceptual model and propositions apply a structuration perspective to provide new insights into how brand value is socially constructed by multiple stakeholders using social media. The focus is on how stakeholder-brand interactions play out across three dimensions of social structure: meaning; norms; and power. We consider how brand meaning (and thus value), emerges out of consensus and dissensus between various stakeholders—brand loyalists and brand rebels—using social media to interact with brands. And how norms of behavior and structures of power guide and legitimize their social media use to reinforce, or potentially transform, brand meaning. Importantly, we consider how brand management can recognize the interactive opportunities provided by different social media platforms and the positions and roles of stakeholders and their social context in considering the social construction of brand value.
Practical Implementation of the Indirect Control to the Direct 3 × 5 Matrix Converter Using DSP and Low-Cost FPGA

The popularity of multiphase drives is increasing due to the growing interest in drives with more than three phases. One promising topology is the multiphase matrix converters, which enable the implementation of a single-stage AC/AC power conversion system with bidirectional power flow capability. In this paper, we present the implementation of indirect control for a practical sample of the direct matrix converter. To reduce the overall cost of the control solution for these types of converters, we utilized low-cost FPGA and DSP. The usage of only DSP itself was not possible due to low number of available PWM output needed for 3 × 5 MxC driving. Another reason is commutation, which must be precise and fast to avoid any hazardous states in the converter. Due to these problems, the authors decided to implement an algorithm of a combination of DSP and FPGA, where FPGA is used for time critical operations. The indirect algorithm treats the converter as two separate parts, the rectifier and the inverter, with the DC-LINK being fictitious. The matrix converter is composed of compact modules, and the entire system is verified. The practical verification demonstrates that matrix converters can produce a wide range of output frequencies and achieve input power factor control. Finally, we compare and review the practical model with the simulation model, examining efficiency and other parameters.
Design of a plastic aspheric Fresnel lens with a spherical shape

A detailed description of the design of a plastic, aspheric Fresnel lens on a spherical surface is provided. The design technique is based on calculating solutions to Snell's law along the lens surface. These lenses were intended for the wavelength range of 8 to 12 mm. However, the method easily applies to lenses designed for other wave- lengths. The procedure used to manufacture the lenses is to construct a diamond-turned master surface, followed by injection molding with high- density polyethylene. © 1997 Society of Photo-Optical Instrumentation Engineers.

Surgical Approach to Liver Metastases in GEP-NET in a Tertiary Reference Center

Simple Summary The choice of the surgical and therapeutic approach for patients suffering from neuroendocrine liver metastases (NELM) plays a central role in the therapeutic strategy. Whilst debulking surgery is widely accepted as an alternative approach for eligible patients, its prognostic influence remains a point of discussion. With the advent of minimally invasive liver surgery (MILS), its applicability for the treatment of neuroendocrine tumors has scarcely been described. Here, we aimed to investigate different surgical strategies in the multimodal treatment of NELM, including minimally invasive approaches. Tumor debulking showed comparable survival outcomes to curative intended liver surgery, and MILS was not inferior to open liver surgery in terms of survival rates and as such should be recommended also in patients with NELM. Abstract Indications for liver resection in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NET) vary from liver resection with curative intent to tumor debulking or tissue sampling for histopathological characterization. With increasing expertise, the number of minimally invasive liver surgeries (MILS) in GEP-NET patients has increased. However, the influence on the oncological outcome has hardly been described. The clinicopathological data of patients who underwent liver resection for hepatic metastases of GEP-NET at the Department of Surgery, Charité—Universitätsmedizin Berlin, were analyzed. Propensity score matching (PSM) was performed to compare MILS with open liver surgery (OLS). In total, 22 patients underwent liver surgery with curative intent, and 30 debulking surgeries were analyzed. Disease-free survival (DFS) was longer than progression-free survival (PFS) (10 vs. 24 months), whereas overall survival (OS) did not differ significantly (p = 0.588). Thirty-nine (75%) liver resections were performed as OLS, and thirteen (25%) as MILS. After PSM, a shorter length of hospital stay was found for the MILS group (14 vs. 10 d, p = 0.034), while neither DFS/PFS nor OS differed significantly. Both curative intended and cytoreductive resection of hepatic GEP-NET metastases achieved excellent outcomes. MILS led to a reduced length of hospital, while preserving a good oncological outcome.
