description: An exactly solvable phase-field theory of dislocation dynamics, strain hardening and hysteresis in ductile single crystals is developed. The theory accounts for: an arbitrary number and arrangement of dislocation lines over a slip plane; the long-range elastic interactions between dislocation lines; the core structure of the dislocations resulting from a piecewise quadratic Peierls potential; the interaction between the dislocations and an applied resolved shear stress field; and the irreversible interactions with short-range obstacles and lattice friction, resulting in hardening, path dependency and hysteresis. A chief advantage of the present theory is that it is analytically tractable, in the sense that the complexity of the calculations may be reduced, with the aid of closed form analytical solutions, to the determination of the value of the phase field at point-obstacle sites. In particular, no numerical grid is required in calculations. The phase-field representation enables complex geometrical and topological transitions in the dislocation ensemble, including dislocation loop nucleation, bow-out, pinching, and the formation of Orowan loops. The theory also permits the consideration of obstacles of varying strengths and dislocation line-energy anisotropy. The theory predicts a range of behaviors which are in qualitative agreement with observation, including: hardening and dislocation multiplication in single slip under monotonic loading; the Bauschinger effect under reverse loading; the fading memory effect, whereby reverse yielding gradually eliminates the influence of previous loading; the evolution of the dislocation density under cycling loading, leading to characteristic `butterfly' curves; and others.

description: Abstract

Monitoring and evaluation (M&E) are crucial for ensuring the efficiency and effectiveness of project implementation in various industries, including telecommunications. This study examines the factors influencing monitoring and evaluation in the telecommunications sector, with a specific focus on project implementation at Somtel Company in Somalia. The research investigates the correlation between stakeholder participation, budgetary allocation, and the training level of the evaluation team in enhancing project performance.

A descriptive research design was employed, utilizing both primary and secondary data sources. Data was collected through structured questionnaires and analyzed using SPSS software. Findings indicate that stakeholder involvement significantly contributes to the success of M&E processes, as it fosters transparency and accountability. Additionally, budget allocation plays a critical role, with sufficient funding positively impacting project execution and M&E outcomes. Furthermore, the study highlights that the level of training among M&E personnel directly influences the quality and effectiveness of monitoring and evaluation activities.

The study concludes that an integrated approach, emphasizing stakeholder engagement, proper funding, and staff training, is essential for improving M&E practices within the telecommunications industry. It recommends that Somtel and other telecom companies strengthen M&E frameworks, allocate adequate resources, and provide regular training to M&E teams to enhance project performance and long-term sustainability.

description: Background: Compulsive eating can be promoted by intermittent access to palatable food and is often accompanied by cognitive deficits and reduction in hippocampal plasticity. Here, we investigated the effects of intermittent access to palatable food on hippocampal function and neurogenesis. Methods: Male Wistar rats were either fed chow for 7 days/week (Chow/Chow group), or fed chow intermittently for 5 days/week followed by a palatable diet for 2 days/week (Chow/Palatable group). Hippocampal function and neurogenesis were assessed either during withdrawal or following renewed access to palatable food. Furthermore, the ability of the uncompetitive N-methyl-d-aspartate receptor (NMDAR) antagonist memantine to prevent the diet-induced memory deficits and block the maladaptive feeding was tested. Results: Palatable food withdrawn Chow/Palatable rats showed both a weakened ability for contextual spatial processing and a bias in their preference for a “novel cue” over a “novel place,” compared to controls. They also showed reduced expression of immature neurons in the dentate gyrus of the hippocampus as well as a withdrawal-dependent decrease of proliferating cells. Memantine treatment was able both to reverse the memory deficits and to reduce the excessive intake of palatable diet and the withdrawal-induced hypophagia in food cycling rats. Conclusions: In summary, our results provide evidence that withdrawal from highly palatable food produces NMDAR-dependent deficits in hippocampal function and a reduction in hippocampal neurogenesis.

description: One loop corrections to the muon decay are studied in a popular and self-consistent version of the Left-Right symmetric model. It is shown quantitatively, that the corrections do not split into those that come from the Standard Model sector and some decoupling terms. For a heavy Spontaneous Symmetry Breaking (SSB) scale of the order of a least 1 TeV, the contributions from the top quark have a logarithmic behaviour and there is a strong quadratic dependence on the heavy Higgs scalar masses. The dependence on the light Higgs boson mass is small. The heavy neutrinos are shown to play an important role, although secondary in comparison with the heavy scalar particles as long as the heavy neutrinos' Majorana Yukawa coupling matrix $h_M$ obeys unitarity bounds.

description: Lighting plays a central role in conveying the essence and depth of the subject in a portrait photograph. Professional photographers will carefully control the lighting in their studio to manipulate the appearance of their subject, while consumer photographers are usually constrained to the illumination of their environment. Though prior works have explored techniques for relighting an image, their utility is usually limited due to requirements of specialized hardware, multiple images of the subject under controlled or known illuminations, or accurate models of geometry and reflectance. To this end, we present a system for portrait relighting: a neural network that takes as input a single RGB image of a portrait taken with a standard cellphone camera in an unconstrained environment, and from that image produces a relit image of that subject as though it were illuminated according to any provided environment map. Our method is trained on a small database of 18 individuals captured under different directional light sources in a controlled light stage setup consisting of a densely sampled sphere of lights. Our proposed technique produces quantitatively superior results on our dataset's validation set compared to prior works, and produces convincing qualitative relighting results on a dataset of hundreds of real-world cellphone portraits. Because our technique can produce a 640 $\times$ 640 image in only 160 milliseconds, it may enable interactive user-facing photographic applications in the future.

description: Methicillin-resistant Staphylococcus aureus (MRSA) sequence type (ST)398 is a livestock associated (LA) lineage with zoonotic potential, especially in humans with live pig contact. The objective of this study was to characterize two S. aureus strains of lineage ST398 (one methicillin-resistant (MRSA), one methicillin-susceptible (MSSA)) isolated from the same nasal sample of a patient admitted in the Intensive-Care Unit of a Spanish Hospital, and with previous occupational exposure to live pigs, by whole-genome-sequencing (WGS). The sample was obtained during routine surveillance for MRSA colonization. Purified genomic DNA was sequenced using Illumina HiSeq 2000 and processed using conventional bioinformatics software. The two isolates recovered were both S. aureus t011/ST398 and showed similar resistance-phenotypes, other than methicillin susceptibility. The possession of antibiotic resistance genes was the same, except for the mecA-gene located in SCCmecV in the MRSA isolate. The MSSA isolate harbored remnants of a SCCmec following the deletion of 17342bp from a recombination between two putative primases. Both isolates belonged to the livestock-associated clade as defined by three canonical single-nucleotide-polymorphisms, and neither possessed the human immune evasion cluster genes, chp, scn, or sak. The core genome alignment showed a similarity of 99.6%, and both isolates harbored the same mobile genetic elements. The two nasal ST398 isolates recovered from the patient with previous occupational exposure to pigs appeared to have a livestock origin and could represent different evolutionary steps of animal-human interface lineage. The MSSA strain was formed as a result of the loss of the mecA gene from the livestock-associated-MRSA lineage.

description: We study the estimation of a single parameter characterizing families of unitary transformations acting on two systems. We consider the situation with the presence of bottleneck, i.e. only one of the systems can be measured to gather information. The estimation capabilities are related to unitaries' generators. In particular, we establish continuity of quantum Fisher information with respect to generators. Furthermore, we find conditions on the generators to achieve the same maximum quantum Fisher information we would have in the absence of bottleneck. We also discuss the usefulness of initial entanglement across the two systems as well as across multiple estimation instances.

description: The study has evaluated the performance of state level animal fairs in Rajasthan using information on arrival and sale of animals and revenue realisation for the period 1996-97 to 2010-11. It was found that on an average both arrival and sale of animals had declined during this period. Small ruminants are rarely brought to these fairs. Only about half of the animals brought are sold with sales to arrival ratio being higher for horses, cattle and buffalo. The major reasons for decline in the arrivals include ban on sale of male cattle below three years of age to buyers from other states, inadequate market infrastructure for humans as well as animals, and lack of facilities of feed and fodder supplies. There is also considerable variation in the arrivals and sales over time. The income from organisation of the fairs had grown faster than the expenditure. The study suggests the need to utilise the surplus for development of facilities in the fairs.

description: 3G and 4G mobile are based on CDMA technology. In order to increase the effectiveness of CDMA receivers large amount of effort is invested to develop suitable multi-user detector techniques. However, at this moment there are only suboptimal solutions available because of the rather high complexity of optimal detectors. One of the possible receiver technologies can be the quantum assisted computing devices which allows high level parallelism in computation. The first commercial devices are estimated by 2004, which meets the advert of 3G and 4G systems. In this paper we introduce a novel quantum computation based Quantum Multi-user detection (QMUD) algorithm, employing simple Positive Operation Valued Measurement (POVM), which provides optimal solution. The proposed algorithm is robust to any kind of noise.

description: Combinatorial chemo-photodynamic therapy is regared as effective cancer therapy strategy, which could be realized via multiple nano-drug delivery system. Herein, novel high payload nanoparticles stabilized by amphiphilic block polymer cholesterol-b-poly(ethylene glycol) (PEG)2000 (Chol-PEG2000) were fabricated for loading chemotherapeutic drug 10-hydroxycamptothecin (HCPT) and photosensitizer chlorin e6 (Ce6). The obtained HCPT/Ce6 NPs showed uniform rod-like morphology with a hydration diameter of 178.9 ± 4.0 nm and excellent stability in aqueous solution. HCPT and Ce6 in the NPs displayed differential release profile, which was benefit for preferentially exerting the photodynamic effect and subsequently enhancing the sensitivity of the cells to HCPT. Under laser irradiation, the NPs demonstrated fantastic in vitro and in vivo anticancer efficiency due to combinational chemo-photodynamic therapy, enhanced cellular uptake effectiveness, and superb intracellular ROS productivity. Besides, the NPs were proved as absent of systemic toxicity. In summary, this nanoparticle delivery system could be hopefully utilized as effective cancer therapy strategy for synergistically exerting combined chemo-photodynamic therapy in clinic.

description: An attempt has been made in this study to find out the relationship among the farm mechanisation, Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS), labour supply and other factors mainly using state-wise data pertaining to paddy and wheat crops covering the period from 2000- 01 to 2010-11. To measure the regression of various growth factors including MGNREGS on the use of farm machineries, regressions is computed using panel data with fixed effects models. The descriptive analysis of the study shows that the machine labour cost in real value (which is used as a proxy variable to reflect the level of farm mechanisation) incurred for cultivating both paddy and wheat has increased considerably during post MGNREGS period in almost all the states selected for the analysis. The machine labour cost incurred for cultivating paddy has increased substantially in states like Andhra Pradesh, Tamil Nadu, Karnataka and Madhya Pradesh after the implementation of MGNREGS, while the same increase was found very high in Madhya Pradesh, Himachal Pradesh, Uttar Pradesh and Punjab in wheat cultivation. In most states where the machine labour cost has increased substantially, the use of human labour in man-hours has declined sharply in both paddy and wheat, confirming the fact that farm machineries are used to substitute the human labour especially after implementing MGNREGS. The regression results computed using panel data suggest that the factors determining the use of farm machineries is not the same between the two major crops selected for the study. Besides MGNREGS dummy, the factors such as coverage of irrigation, yield enhancing inputs cost, land-labour ratio and human labour use in man-hours have significantly influenced the use of machine labour in paddy cultivation. But, in the case of wheat crop, irrigation coverage and land-labour ratio has not significantly influenced the use of machineries. The MGNREGS dummy used to capture its impact on farm mechanisation has turned out to be positive and significant in both paddy and wheat cultivation suggesting that the level of farm mechanisation has increased after its implementation of national rural employment guarantee scheme.

description: Plastic deformation in metals is heavily influenced by the loading direction. Studies have explored its effects on multiple mechanisms by analysing individual dislocations, but there is currently no systematic way of rationalising the cooperative behaviour of the different slip systems for arbitrary stress tensors. The current study constitutes the foundation of a new orientation analysis framework for face-centred cubic crystals by introducing "stress orientation maps", graphical tools to simultaneously analyse the effects of loading orientation on the stress state of the a 2 〈 1 1 ¯ 0 〉 { 111 } and a 6 〈 112 〉 { 111 } slip systems in a comprehensive, yet intuitive way. Relationships between the Schmid and Escaig stresses are described from geometrical constraints of the slip systems in the crystal structure, linking the dislocation behaviour on a slip plane with the stress tensor via a one parameter description. The case of uniaxial loading along different orientations within the fundamental sector of the unit cell is explored to describe the physical basis, properties and capabilities of this framework. The stress normal to the slip plane is then considered in the analysis via an extension of the Mohr’s circles. The orientation dependence of two twin nucleation mechanisms from the literature are examined as examples of how the stress orientation maps can be used.

description: The paper examines the effective and efficient use of labour in Indian agriculture in the context of farm mechanisation. It explores the rationality of labour use in paddy production across states with the help of Stochastic Frontier Production Function analysis based on plot level data under the Cost of Cultivation Scheme during 2009-10. The study analyses the productivity, unit cost and farm income differentials and the variation in the extent of farm mechanisation and other inputs use in paddy production between and within states during 2004-05 to 2010-11. It also examines the impact of machine use on the production, productivity, cost and profitability in paddy production in India based on aggregated and disaggregated data. It is observed that there is no rational use of human labour in Indian agriculture (i.e., the present study rejects the hypothesis of equality between marginal productivity of labour and average wage rate). Machine use in agricultural production plays an important role in the increase in productivity and reduction of unit cost of production resulting profitable making farming viable in India. There is a great variation in the degree of farm mechanisation across Indian states but there is a good indication that inequality in input use and the variation in access to modern agricultural technology has decreased among the states during post-WTO period.

description: Supernova neutrinos could be well-suited for probing neutrino decay, since decay may be observed even for very small decay rates or coupling constants. We will introduce an effective operator framework for the combined description of neutrino decay and neutrino oscillations for supernova neutrinos, which can especially take into account two properties: One is the radially symmetric neutrino flux, allowing a decay product to be re-directed towards the observer even if the parent neutrino had a different original direction of propagation. The other is decoherence because of the long baselines for coherently produced neutrinos. We will demonstrate how to use this effective theory to calculate the time-dependent fluxes at the detector. In addition, we will show the implications of a Majoron-like decay model. As a result, we will demonstrate that for certain parameter values one may observe some effects which could also mimic signals similar to the ones expected from supernova models, making it in general harder to separate neutrino and supernova properties.

description: Abstract: India is located at a critical geographic crossroads for understanding the dispersal of Homo sapiens out of Africa and into Asia and Oceania. Here we report evidence for long-term human occupation, spanning the last ~80 thousand years, at the site of Dhaba in the Middle Son River Valley of Central India. An unchanging stone tool industry is found at Dhaba spanning the Toba eruption of ~74 ka (i.e., the Youngest Toba Tuff, YTT) bracketed between ages of 79.6 ± 3.2 and 65.2 ± 3.1 ka, with the introduction of microlithic technology ~48 ka. The lithic industry from Dhaba strongly resembles stone tool assemblages from the African Middle Stone Age (MSA) and Arabia, and the earliest artefacts from Australia, suggesting that it is likely the product of Homo sapiens as they dispersed eastward out of Africa.

description: We analyze the onset and initial expansion of the 2018 Martian Global Dust Storm (GDS 2018) using ground-based images in the visual range. This is the first case of a confirmed GDS initiating in the Northern Hemisphere. A dusty area extending about 1.4x10e5 km^2 and centered at latitude +31.7° $\pm$ 1.8° and west longitude 18° $\pm$ 5°W in Acidalia Planitia was captured on 30 and 31 May 2018 (Ls = 184.9°). From 1 to 8 June, daily image series showed the storm expanding southwards along the Acidalia corridor with velocities of 5 m/s, and simultaneously progressing eastwards and westwards with horizontal velocities ranging from 5 to 40 m/s. By 8 June the dust reached latitude -55° and later penetrated in the South polar region, whereas in the North the dust progression stopped at latitude +46°. We compare the onset and expansion stage of this GDS with the previous confirmed storms.

description: Abstract: Collagen fibrils are central to the molecular organization of the extracellular matrix (ECM) and to defining the cellular microenvironment. Glycation of collagen fibrils is known to impact on cell adhesion and migration in the context of cancer and in model studies, glycation of collagen molecules has been shown to affect the binding of other ECM components to collagen. Here we use TEM to show that ribose-5-phosphate (R5P) glycation of collagen fibrils – potentially important in the microenvironment of actively dividing cells, such as cancer cells – disrupts the longitudinal ordering of the molecules in collagen fibrils and, using KFM and FLiM, that R5P-glycated collagen fibrils have a more negative surface charge than unglycated fibrils. Altered molecular arrangement can be expected to impact on the accessibility of cell adhesion sites and altered fibril surface charge on the integrity of the extracellular matrix structure surrounding glycated collagen fibrils. Both effects are highly relevant for cell adhesion and migration within the tumour microenvironment.

description: In a previous communication by two of us, Phys. Rev. Lett. 81, 1373 (1998), the gauge-dependent deviations of the on-shell mass and total decay width from their gauge-independent pole counterparts were investigated at leading order for the Higgs boson of the Standard Model. In the case of the widths, the deviation was found to diverge at unphysical thresholds, m_H = 2 root{xi_V} m_V (V = W,Z), in the R_xi gauge. In this Brief Report, we demonstrate that these unphysical threshold singularities are properly eliminated if a recently proposed definition of wave-function renormalization for unstable particles is invoked.

description: Agritourism can be a great source of entertainment, income, and education. In order to model the key factors that affect its adoption among small farmers in North Carolina, a case study approach is employed to set the tone for further analysis of the subject area. Anthropological characteristics such as age, gender, household income before taxes, ethnicity, educational background and operational factors such as total acreage, geographical information, and economic situation of the farm are identified as recurring elements. Four farms were interviewed in the case study to identify the choices and challenges of operating an agritourism enterprise. The most common primary challenges are expenses, access to capital and liability issues. The most common goal for engaging agritourism is income generation and less common goals include educating the public about agriculture as well as family heritage.
Redundancy in Logic I: CNF Propositional Formulae

description: A knowledge base is redundant if it contains parts that can be inferred from the rest of it. We study the problem of checking whether a CNF formula (a set of clauses) is redundant, that is, it contains clauses that can be derived from the other ones. Any CNF formula can be made irredundant by deleting some of its clauses: what results is an irredundant equivalent subset (I.E.S.) We study the complexity of some related problems: verification, checking existence of a I.E.S. with a given size, checking necessary and possible presence of clauses in I.E.S.'s, and uniqueness. We also consider the problem of redundancy with different definitions of equivalence.

description: PALLADIUM and IRIDIUM studies demonstrated efficacy and safety of indacaterol/mometasone (IND/MF) versus salmeterol/fluticasone (SAL/FLU). This post hoc analysis of pooled data from PALLADIUM and IRIDIUM studies evaluated efficacy and safety of IND/MF versus SAL/FLU in Asian patients with inadequately controlled asthma. Both studies were Phase III, 52-week, randomized, double-blind, active-controlled that included patients with predicted pre-bronchodilator FEV1 (PALLADIUM, ≥50%–<85%; IRIDIUM, <80%), ACQ-7 score ≥1.5. Patients treated with IND/MF high- (150/320 μg) or medium-dose (150/160 μg) or SAL/FLU high-dose (50/500 μg) were included. Lung function, asthma control, and asthma exacerbations were evaluated. In total, 323 patients (IND/MF high-dose, n = 107; IND/MF medium-dose, n = 106, SAL/FLU high-dose, n = 110) were included. IND/MF high-dose showed improvement in trough FEV1 versus SAL/FLU high-dose at Weeks 26 (Δ, 42 mL; 95% CI, −35 to 120 mL), and 52 (Δ, 41 mL; 95% CI, −37 to 120 mL). IND/MF high-dose exhibited numerically greater improvement in ACQ-7 score versus SAL/FLU high-dose at Weeks 26 (Δ, −0.215; 95% CI, −0.385 to −0.044) and 52 (Δ, −0.176; 95% CI, −0.348 to −0.005). Improvements in trough FEV1 and ACQ-7 score were comparable between IND/MF medium-dose and SAL/FLU high-dose. IND/MF high- and medium-dose showed reductions in moderate or severe (45%; 30%), severe (39%; 41%), and all (9%; 25%) exacerbations, respectively, versus SAL/FLU high-dose over 52 weeks. All treatments were well tolerated. Once-daily, single-inhaler IND/MF high-dose improved lung function with better asthma control, reduced asthma exacerbations with comparable safety versus twice-daily SAL/FLU high-dose. IND/MF medium-dose showed comparable outcomes to SAL/FLU high-dose at a reduced steroid dose.
Urban Ruralism: Greater Angkor and the Nature of Low-Density Urbanism

Subjects: subject: Urbanism, Khmer, Maya, low-density

description: The City of Greater Angkor in Modern Cambodia incorporates settlement forms that are found in rural Khmer settlement throughout the region. This thesis argues that the mode of urbanization found at Angkor, termed low-density urbanism, allows for the maintaining of more parochial forms of identity. By combining the analysis of Angkor with analysis of Mayan examples of low-density urbanism, this thesis further argues that this type of urbanism is uniquely suited to preserving rural identities and lifeways within urban society

description: In the community, Meals on Wheels (MoW) programmes are instrumental in the delivery of meals to nutritionally vulnerable older adults. This qualitative evidence synthesis aimed to explore the perceptions and experiences among volunteers of MoW services of their role in supporting nutrition care. Scopus, PubMed, CINAHL, Web of Science, Embase, MEDLINE, and PsycINFO were searched employing qualitative data collection and analysis methods. Results were synthesized using Thomas and Harden’s three step approach for thematic synthesis. Three articles were included and two themes were identified: (1) complexity in coordinating MoW to ensure service delivery, and (2) the MoW volunteers’ perception of their role in providing nutrition care was eclipsed by the social element of their role. While MoW is pivotal to support older adults’ independence, challenges like staffing, funding constraints, and limited community awareness of the service persist. Volunteers’ express positivity but face concerns about time commitment and replacement recruitment. Exploring MoW volunteers’ broader roles in food insecurity is imperative to understand and address the complex dynamics of providing nutrition care and support to older adults.
