description: In this work we review the efforts that have been done to study the excitation of the standing fast kink body mode in coronal loops. We mainly focus on the time-dependent problem, which is appropriate to describe flare or CME induced kink oscillations. The analytical and numerical studies in slab and cylindrical loop geometries are reviewed. We discuss the results from very simple one-dimensional models to more realistic (but still simple) loop configurations. We emphasise how the results of the initial value problem complement the eigenmode calculations. The possible damping mechanisms of the kink oscillations are also discussed.

description: In this Letter we study the evolution of the higher-order squeezing, namely, $n$th-order single-mode squeezing, sum- and difference-squeezing for the codirectional Kerr nonlinear coupler. We show that the amount of squeezing decreases when $n$, i.e. the squeezing order, increases. For specific values of the interaction parameters squeezing factors exhibit a series of revival-collapse phenomena, which become more pronounced when the value of $n$ increases. Sum-squeezing can provide amounts of squeezing greater than those produced by the $n$th higher-order ($n\geq 2$) squeezing for the same values of interaction parameters and can map onto amplitude-squared squeezing. Further, we prove that the difference-squeezing is not relevant measure for obtaining information about squeezing from this device.

description: Background: Many lesbian and bisexual (LB) women veterans may have been targets of victimization in the military based on their gender and presumed sexual orientation, and yet little is known regarding the health or mental health of LB veterans, nor the degree to which they feel comfortable receiving care in the VA. Objective: The purpose of this study was to examine the prevalence of mental health and gender-specific conditions, VA healthcare satisfaction and trauma exposure among LB veterans receiving VA care compared with heterosexually-identified women veterans receiving. Design: Prospective cohort study of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) women veterans at two large VA facilities. Participants: Three hundred and sixty five women veterans that completed a baseline survey. Thirty-five veterans (9.6 %) identified as gay or lesbian (4.7 %), or bisexual (4.9 %). Main Measures: Measures included sexual orientation, military sexual trauma, mental and gender-specific health diagnoses, and VA healthcare utilization and satisfaction. Key Results: LB OEF/OIF veterans were significantly more likely to have experienced both military and childhood sexual trauma than heterosexual women (MST: 31 % vs. 13 %, p001; childhood sexual trauma: 60 % vs. 36 %, p=.01), to be hazardous drinkers (32 % vs. 16 %, p=.03) and rate their current mental health as worse than before deployment (35 % vs. 16 %, p.001). Conclusions: Many LB veterans have experienced sexual victimization, both within the military and as children, and struggle with substance abuse and poor mental health. Health care providers working with female Veterans should be aware of high rates of military sexual trauma and childhood abuse and refer women to appropriate VA treatment and support groups for sequelae of these experiences. Future research should focus on expanding this study to include a larger and more diverse sample of lesbian, gay, bisexual, and transgender veterans receiving care at VA facilities across the country. © Society of General Internal Medicine 2012.

description: We report the search for 7Be isotope in the outbursts of the classical nova V6595 Sgr by means of high resolution UVES observations taken at the ESO VLT in April 2021, about two weeks after discovery and under difficult circumstances due to the pandemic. Narrow absorption components with velocities at about -2620 and -2820 km/s, superposed on broader and shallow absorption, are observed in the outburst spectra for the 7BeII 313.0583, 313.1228 nm doublet resonance lines, as well as in several other elements such as CaII, FeI, MgI, NaI, HI but LiI. Using CaII K line as a reference element, we infer N(7Be)/N(H) ~ 7.4 x 10^{-6}, or ~ 9.8 x 10^{-6} when the 7Be decay is taken into account. The 7Be abundance is about half of the value most frequently measured in novae. The possible presence of over-ionization in the layers where 7Be is detected is also discussed. Observations taken at the Telescopio Nazionale Galileo (TNG) in La Palma 91 days after discovery showed prominent emission lines of Oxygen and Neon which allow to classify the nova as ONe type. Therefore, although 7Be is expected to be higher in CO novae, it is found at comparable levels in both nova types.

Mainline railway electrification : an economic feasibility model
Creators: name: Johnston, William David
Publisher: name: University of British Columbia
Year: 2010

description: The projected growth in demand for intercity freight transportation, growth in rail transit in urban areas, the requirements of intercity rail passenger service, and sensitivity to depletion of natural and environmental resources, particularly fuels and air quality, is spurring the evaluation of electric locomotives as an alternative to the diesel-electric. Of all the modes of transportation, only rail can be feasibly converted from petroleum fuel to hydro, coal, or nuclear-fueled electric energy. The technology of electric motive power has continued to improve from that realized in most previous North American large scale electrification projects, both as a result of general technological advance, and of specific efforts by electrified railroads in other countries. Under optimum operating conditions, an electrified, rail line would require less motive power equipment arid could achieve a higher frequency and better level of service than could one utilising diesel locomotives. Electric locomotives could permit faster train runs resulting in improved schedules, more efficient operations, and increased reliability of service due to less down and turn-around time. This study develops a comprehensive computer-based "Railway Electrification Economic Feasibility Model" that may be practically used to determine the potential return if various rail line segments across the country were to be electrified. The Model is developed in a manner that allows various line and locomotive operating parameters to be easily examined to determine the relative sensitivities of traffic mix (freight, express, and passenger) and growth projections, operating and locomotive characteristics, capital requirement and staging, fuel costs, and projected labor and capital inflation rates on the project viability. As the first stage in an electrification economic feasibility analysis, the Model may be employed, using rough traffic, capital and annual operating cost projections, to determine which line segments show sufficient potential return on electrification capital to justif more detailed engineering, marketing, and operating studies. The results of these detailed studies can then be usad in the Model to further refine the potential return on invested capital and, using the opportunity cost of capital, determine the year electrification will become economically viable. As the Model is computer based, it is relatively easy to vary some, or all, of the input parameters and so evaluate the sensitivity and risk of the various parameters on the financial viability of the project. The rail line used to test the model showed an extremely attractive return on invested capital. The electrification parameters found to have the greatest effect on the project viability were the equation of electric to diesel locomotives required, fixed facilities construction costs, electric locomotive purchase costs, and relative fuel cost escalation rates.

description: The compound Ce2PdIn8 is a recently discovered novel member of the series Ce(n)TIn(3n+2), where T = d-electron transition metal, and n = 1 or 2. So far, only the phases with T = Co, Rh and Ir have been intensively studied for their unconventional superconducting behaviors at low temperatures. By means of magnetic susceptibility, electrical resistivity and heat capacity measurements we provide evidence that also Ce2PdIn8 has a superconducting ground state with strong heavy-fermion character. The clean-limit superconductivity sets in at Tc = 0.7 K at ambient pressure, likely at a verge of a quantum phase transition that manifests itself in a form of distinct non-Fermi liquid features in the bulk normal state characteristics.

description: Can crowd workers be trusted to judge whether news-like articles circulating on the Internet are misleading, or does partisanship and inexperience get in the way? And can the task be structured in a way that reduces partisanship? We assembled pools of both liberal and conservative crowd raters and tested three ways of asking them to make judgments about 374 articles. In a no research condition, they were just asked to view the article and then render a judgment. In an individual research condition, they were also asked to search for corroborating evidence and provide a link to the best evidence they found. In a collective research condition, they were not asked to search, but instead to review links collected from workers in the individual research condition. Both research conditions reduced partisan disagreement in judgments. The individual research condition was most effective at producing alignment with journalists' assessments. In this condition, the judgments of a panel of sixteen or more crowd workers were better than that of a panel of three expert journalists, as measured by alignment with a held out journalist's ratings.

description: Bats are diverse and ecologically important, but are also subject to a suite of severe threats. Evidence for localized bat mortality from these threats is well-documented in some cases, but long-term changes in regional populations of bats remain poorly understood. Bat hibernation surveys provide an opportunity to improve understanding, but analysis is complicated by bats' cryptic nature, non-conformity of count data to assumptions of traditional statistical methods, and observation heterogeneities such as variation in survey timing. We used generalized additive mixed models (GAMMs) to account for these complicating factors and to evaluate long-term, regional population trajectories of bats. We focused on four hibernating bat species - little brown myotis (Myotis lucifugus), tri-colored bat (Perimyotis subflavus), Indiana myotis (M. sodalis), and northern myotis (M. septentrionalis) - in a four-state region of the eastern United States during 1999-2011.Our results, from counts of nearly 1.2 million bats, suggest that cumulative declines in regional relative abundance by 2011 from peak levels were 71% (with 95% confidence interval of ±11%) in M. lucifugus, 34% (±38%) in P. subflavus, 30% (±26%) in M. sodalis, and 31% (±18%) in M. septentrionalis. The M. lucifugus population fluctuated until 2004 before persistently declining, and the populations of the other three species declined persistently throughout the study period. Population trajectories suggest declines likely resulted from the combined effect of multiple threats, and indicate a need for enhanced conservation efforts. They provide strong support for a change in the IUCN Red List conservation status in M. lucifugus from Least Concern to Endangered within the study area, and are suggestive of a need to change the conservation status of the other species. Our modeling approach provided estimates of uncertainty, accommodated non-linearities, and controlled for observation heterogeneities, and thus has wide applicability for evaluating population trajectories in other wildlife species.

description: We address the problem of interference using the Heisenberg picture and highlight some new aspects through the use of pre-selection, post-selection, weak measurements, and modular variables, We present a physical explanation for the different behaviors of a single particle when the distant slit is open or closed: instead of having a quantum wave that passes through all slits, we have a localized particle with non-local interactions with the other slit(s). We introduce a Gedankenexperiment to measure this non-local exchange. While the Heisenberg picture and the Schrodinger pictures are equivalent formulations of quantum mechanics, nevertheless, the results discussed here support a new approach which has led to new insights, new intuitions, new experiments, and even the possibility of new devices that were missed from the old perspective.

description: While third-generation CMB experiments have allowed to release the first maps of Compton-$y$ distortion due to thermal Sunyaev-Zeldovich (SZ) effect, next-generation CMB experiments should allow us to map also the electron gas temperature, $T_{\rm e}$, across the sky through the detection of relativistic corrections to the thermal SZ effect. We discuss about experimental requirements to break the $y$-$T_{\rm e}$ degeneracy of the observed SZ intensity, and propose a new component separation approach based on moment expansion to disentangle the $y$ and $T_{\rm e}$ observables of the relativistic SZ effect while mitigating foregrounds. We show how our approach offers a new spectroscopic view of the clusters not only across frequencies but now also across temperatures. We also show how the relativistic electron temperature power spectrum provides a new cosmological observable which may complement the Compton-$y$ map power spectrum to break some of the parameter degeneracies in future cosmological SZ analyses.

description: Icy pebbles may play an important role in planet formation close to the water ice line of protoplanetary discs. There, dust coagulation is more efficient and re-condensation of vapor on pebbles may enhance their growth outside the ice line. Previous theoretical studies showed that disruption of icy pebbles due to sublimation increases the growth rate of pebbles inside and outside the ice line, by freeing small silicate particles back in the dust reservoir of the disc. However, since planet accretion is dependent on the Stokes number of the accreting pebbles, the growth of planetesimals could be enhanced downstream of the ice line if pebbles are not disrupting upon sublimation. We developed two experimental models of icy pebbles using different silicate dusts, and we exposed them to low-temperature and low-pressure conditions in a vacuum chamber. Increasing the temperature inside the chamber, we studied the conditions for which pebbles are preserved through sublimation without disrupting. We find that small silicate particles ($<50$um) and a small quantity of ice (around $15$% pebble mass) are optimal conditions for preserving pebbles through sublimation. Furthermore, pebbles with coarse dust distribution ($100-300$um) do not disrupt if a small percentage ($10-20$% mass) of dust grains are smaller than $50$um. Our findings highlight how sublimation is not necessarily causing disruption, and that pebbles seem to survive fast sublimation processes effectively.
A model to determine service facility requirements

Publisher: name: University of British Columbia
Year: 2010

description: Credit unions have difficulty in estimating the facility requirements which will enable them to provide adequate member service. Due to the recent growth in membership, most credit unions have had to enlarge their facility to one which would adequately accommodate the present membership as well as provide for expected future growth in operations. The high cost of expansion has made it necessary to accurately determine their facility requirements. B.C. Central Credit Union, a service centre which provides professional assistance to credit unions and co-operatives throughout British Columbia, was concerned with the solution of this problem and first looked to how other organizations tried to solve their facility planning problems. A number of organizations have developed, or attempted to develop, facility planning models. Some have resulted in complete failure and have been abandoned. Others could not answer enough of the questions that credit union managers needed to know about their facility requirements. The management of B.C. Central Credit Union decided tto acquire the services of the author for the purpose of designing and implementing a facility planning model. After a preliminary investigation of the problem and discussions with credit union managers, it was decided that a simulation model would be the most appropriate management tool to use. The scope of the project was to develop and implement a simulation model to accurately determine present and future teller facility requirements (wickets and queuing area) which will enable a credit union to provide adequate member service. The teller facility is simulated under varying conditions to determine the required number of wickets and queuing area for a given credit union. It is shown that the model is sensitive to the approximation of the teller service time distribution and the method of data collection on member arrivals. A credit union's teller facility requirements as well as the level of service are shown to be very dependent on the operating policy to regulate the number of wickets which are available. At present, two credit unions have benefited considerably from the simulation model. In both cases, the management of the credit union had decided to build a new enlarged facility because the existing credit union could not adequately accommodate its members. The simulation model showed that only a change in the facility layout was required. The credit unions reversed their decision to build a new facility and simply changed the layout. Both are presently operating effectively with the new layout and have avoided the expense of a new building.

description: The exact evaluation of the molecular ground state in quantum chemistry requires an exponentially increasing computational cost. Quantum computation is a promising way to overcome the exponential problem using polynomial-time quantum algorithms. A quantum-classical hybrid optimization scheme known as the variational quantum eigensolver(VQE) is preferred for noisy intermediate-scale quantum devices. However, the circuit depth becomes one of the bottlenecks of its application to large molecules of more than 20 qubits. In this work, we employ the point group symmetry to reduce the number of operators in constructing ansatz so as to achieve a more compact quantum circuit. We illustrate this methodology with a series of molecules ranging from LiH(12 qubits) to C2H4(28 qubits). A significant reduction of up to 82% of the operator numbers is reached on C2H4, which enables the largest molecule ever numerically simulated by VQE-UCC to the best of our knowledge. This also shed light into the further work of this direction to construct even shallower ansatz with enough expressive power and simulate even larger scale system.

description: We present an investigation of candidate Infrared Dark Cloud cores as identified by Simon et al. (2006) located within the SCUBA Legacy Catalogue. After applying a uniform noise cut to the Catalogue data we identify 154 Infrared Dark Cloud cores that were detected at 850um and 51 cores that were not. We derive column densities for each core from their 8um extinction and find that the IRDCs detected at 850um have higher column densities (a mean of 1.7x10^22 cm-2) compared to those cores not detected at 850um (a mean of 1.0x10^22 cm-2). Combined with sensitivity estimates, we suggest that the cores not detected at 850um are low mass, low column density and low temperature cores that are below the sensitivity limit of SCUBA at 850um. For a subsample of the cores detected at 850um those contained within the MIPSGAL area) we find that two thirds are associated with 24um sources. Cores not associated with 24um emission are either ``starless'' IRDC cores that perhaps have yet to form stars, or contain low mass YSOs below the MIPSGAL detection limit. We see that those ``starless'' IRDC cores and the IRDC cores associated with 24um emission are drawn from the same column density population and are of similar mass. If we then assume the cores without 24um embedded sources are at an earlier evolutionary stage to cores with embedded objects we derive a statistical lifetime for the quiescent phase of a few 10^3-10^4 years. Finally, we make conservative predictions for the number of observed IRDCs that will be observed by the Apex Telescope Galactic Plane Survey (ATLASGAL), the Herschel Infrared Galactic Plane Survey (Hi-GAL), the JCMT Galactic Plane Survey (JPS) and the SCUBA-2 ``All Sky'' Survey (SASSy).

description: Before quantum error correction (QEC) is achieved, quantum computers focus on noisy intermediate-scale quantum (NISQ) applications. Compared to the well-known quantum algorithms requiring QEC, like Shor's or Grover's algorithm, NISQ applications have different structures and properties to exploit in compilation. A key step in compilation is mapping the qubits in the program to physical qubits on a given quantum computer, which has been shown to be an NP-hard problem. In this paper, we present OLSQ-GA, an optimal qubit mapper with a key feature of simultaneous SWAP gate absorption during qubit mapping, which we show to be a very effective optimization technique for NISQ applications. For the class of quantum approximate optimization algorithm (QAOA), an important NISQ application, OLSQ-GA reduces depth by up to 50.0% and SWAP count by 100% compared to other state-of-the-art methods, which translates to 55.9% fidelity improvement. The solution optimality of OLSQ-GA is achieved by the exact SMT formulation. For better scalability, we augment our approach with additional constraints in the form of initial mapping or alternating matching, which speeds up OLSQ-GA by up to 272X with no or little loss of optimality.

description: Foamy viruses are complex retroviruses that have been shown to be transmitted from nonhuman primates to humans. In Bangladesh, infection with simian foamy virus (SFV) is ubiquitous among rhesus macaques, which come into contact with humans in diverse locations and contexts throughout the country. We analyzed microsatellite DNA from 126 macaques at six sites in Bangladesh in order to characterize geographic patterns of macaque population structure. We also included in this study 38 macaques owned by nomadic people who train them to perform for audiences. PCR was used to analyze a portion of the proviral gag gene from all SFV-positive macaques, and multiple clones were sequenced. Phylogenetic analysis was used to infer long-term patterns of viral transmission. Analyses of SFV gag gene sequences indicated that macaque populations from different areas harbor genetically distinct strains of SFV, suggesting that geographic features such as forest cover play a role in determining the dispersal of macaques and SFV. We also found evidence suggesting that humans traveling the region with performing macaques likely play a role in the translocation of macaques and SFV. Our studies found that individual animals can harbor more than one strain of SFV and that presence of more than one SFV strain is more common among older animals. Some macaques are infected with SFV that appears to be recombinant. These findings paint a more detailed picture of how geographic and sociocultural factors influence the spectrum of simian-borne retroviruses. © 2013 SSCC. All rights reserved.

This work proposes a revisited naive Bayes classification of the X-ray sources in the Swift-XRT and XMM-Newton catalogs into four classes -- AGN, stars, X-ray binaries (XRBs) and cataclysmic variables (CVs) -- based on their spatial, spectral and timing properties and their multiwavelength counterparts. An outlier measure is used to identify objects of other natures. The classifier is optimized to maximize the classification performance of a chosen class (here XRBs) and it is adapted to data mining purposes.Methods. We augmented the X-ray catalogs with multiwavelength data, source class, and variability properties. We then built a reference sample of about 25000 X-ray sources of known nature. From this sample the distribution of each property was carefully estimated and taken as reference to assign probabilities of belonging to each class. The classification was then performed on the whole catalog, combining the information from each property.Results. Using the algorithm on the Swift reference sample we retrieved 99%, 98%, 92% and 34% of AGN, stars, XRBs, and CVs, respectively, and the false positive rates are 3%, 1%, 9% and 15%. Similar results are obtained on XMM sources. When applied to a carefully selected test sample, representing 55% of the X-ray catalog, the classification gives consistent results in terms of distributions of source properties. A substantial fraction of sources not belonging to any class is efficiently retrieved using the outlier measure, as well as AGN and stars with properties deviating from the bulk of their class. Our algorithm is then compared to a random forest method; the two showed similar performances but the algorithm presented in this paper improved insight into the grounds of each classification.Conclusions. This robust classification method can be tailored to include additional or different source classes and can be applied to other X-ray catalogs. The transparency of the classification compared to other methods makes it a useful tool in the search for homogeneous populations or rare source types, including multi-messenger events. Such a tool will be increasingly valuable with the development of surveys of unprecedented size, such as LSST, SKA and Athena, and the search for counterparts of multi-messenger events.

description: Quantum computing has recently exhibited great potentials in predicting chemical properties for various applications in drug discovery, material design, and catalyst optimization. Progress has been made in simulating small molecules, such as LiH and hydrogen chains of up to 12 qubits, by using quantum algorithms such as variational quantum eigensolver (VQE). Yet, originating from limitations of the size and the fidelity of near-term quantum hardware, how to accurately simulate large realistic molecules remains a challenge. Here, integrating an adaptive energy sorting strategy and a classical computational method, the density matrix embedding theory, which effectively finds a shallower quantum circuit and reduces the problem size, respectively, we show a means to circumvent the limitations and demonstrate the potential toward solving real chemical problems. We numerically test the method for the hydrogenation reaction of C6H8 and the equilibrium geometry of the C18 molecule, with basis sets up to cc-pVDZ (at most 144 qubits). The simulation results show accuracies comparable to those of advanced quantum chemistry methods such as coupled-cluster or even full configuration interaction, while the number of qubits required is reduced by an order of magnitude (from 144 qubits to 16 qubits for the C18 molecule) compared to conventional VQE. Our work implies the possibility of solving industrial chemical problems on near-term quantum devices.

description: The gas mass fraction in galaxy clusters is a convenient tool to use in the context of cosmological studies. Indeed this quantity allows to constrain the universal baryon fraction $Ω_b/Ω_m$, as well as other parameters like the matter density $Ω_m$, the Hubble parameter $h$ or the Equation of State of Dark Energy $w$. This gas mass fraction is also sensitive to baryonic effects that need to be taken into account, and that translate into nuisance parameters. Two of them are the depletion factor $Υ$, and the hydrostatic mass bias $B = (1 - b)$. The first one describes how baryons are depleted in clusters with respect to the universal baryon fraction, while the other encodes the bias coming from the fact that the mass is deduced from X-ray observations under the hypothesis of hydrostatic equilibrium. We will show preliminary results, obtained using the {\it Planck}-ESZ clusters observed by XMM-{\it Newton}, on both cosmological and cluster parameters. We will notably discuss the investigation on a possible redshift dependence of the mass bias, which is considered to be non-existent in hydrodynamic simulations based on $Λ$-CDM, and compare our results with other studies.

description: © Wolters Kluwer Health, Inc. All rights reserved. Objectives The aim of this study was to assess patient safety culture (PSC) in maternal and child health (MCH) institutions in China and its individual, organizational, and regional variations. Methods Using the PSC survey for MCH institutions (PSCS-MCHI), 2021 valid respondents from 25 participating institutions were investigated in three regions (Beijing, Zhejiang, and Jiangxi) of China. Patient safety culture and its subscale scores (1-5) and factors associated with PSC as revealed by multilevel modeling. Results The respondents had an average PSC score of 3.55 (SD = 0.35), with subscale scores ranging between 2.46 ("staffing and workload") and 4.02 ("work commitment"). There were limited regional differences in PSC: a three-level regression model was only confirmed for the subscale "staff empowerment"(P = 0.006). However, significant organizational variations in PSC were evident: a two-level regression model was assumed for the PSC scale and nine subscales (P < 0.001). The fixed-effect models showed that male respondents, frontline workers, those who were in their mid-career (11-20 y), overloaded (=9 hours), and had a masters or higher degree reported worse PSC. Frontline workers were less positive than managers in ratings on "managerial response to risks"(-0.11 [-0.20 to -0.02]), "management support"(-0.18 [-0.28 to -0.07]), and "staff empowerment"(-0.23[-0.35 to -0.11]). Conclusions Patient safety culture in MCH institutions is shaped by organizational and individual characteristics. We observed a gap in perceived PSC between frontline worker, who are less positive, and managers. Actions for improving PSC should consider interventions on organizational management (such as appropriate staffing and workload management) and engagement of frontline workers in the development of management and training activities.
Detection of Myoglobin with an Open-Cavity-Based Label-Free Photonic Crystal Biosensor

Publisher: name: My University
Year: 2013

description: The label-free detection of one of the cardiac biomarkers, myoglobin, using a photonic-crystal-based biosensor in a total-internal-reflection configuration (PC-TIR) is presented in this paper. The PC-TIR sensor possesses a unique open optical microcavity that allows for several key advantages in biomolecular assays. In contrast to a conventional closed microcavity, the open configuration allows easy functionalization of the sensing surface for rapid biomolecular binding assays. Moreover, the properties of PC structures make it easy to be designed and engineered for operating at any optical wavelength. Through fine design of the photonic crystal structure, biochemical modification of the sensor surface, and integration with a microfluidic system, we have demonstrated that the detection sensitivity of the sensor for myoglobin has reached the clinically significant concentration range, enabling potential usage of this biosensor for diagnosis of acute myocardial infarction. The real-time response of the sensor to the myoglobin binding may potentially provide point-of-care monitoring of patients and treatment effects.

description: Despite Cambodia's rapid economic growth in the most recent decade, levels of poverty and malnutrition remain high. Home garden vegetable production combined with nutrition training has the potential to abate these problems through the increased production and intake of nutrient-dense vegetables by household members and the creation of income for women from selling some of the produce. Evidence for the nutritional impact of home garden interventions is available for low income countries in Africa and Asia, but the evidence base remains small (Ruel and Alderman 2013; DFID 2014). For Cambodia, Olney et al. (2009) previously evaluated the impact of the homestead food production program of Hellen Keller International. Their study found that households included in the program produced and consumed more fruit and vegetables and that this was associated with greater dietary diversity, though not with improved maternal and child health and nutritional outcomes. The USAID-funded project "Deploying vegetable seed kits to tackle malnutrition in Cambodia" (USAID Award Number: AID-BFS-IO-12-00004) aims to contribute to reduced malnutrition, especially of women and children, through diet diversification by promoting the production and consumption of vegetables as affordable sources of essential vitamins and micronutrients. The project aims to achieve this through the deployment of diet-enhancing vegetable home garden seed kits and the development of household gardens in combination with nutrition training in each country in partnership with private seed companies, local and national governments, nutrition & health partners, and USAID mission and programs. The project is planned for a period of 3 years from October 2015 to September 2018. The objective of this study is to evaluate the impact of the project on key nutritional outcome indicators by applying a randomized controlled trial design. This document describes the intervention design and study implementation plan.

description: In a large number of problems the high dimensionality of the search space, the vast number of variables and the economical constrains limit the ability of classical techniques to reach the optimum of a function, known or unknown. In this thesis we investigate the possibility to combine approaches from advanced statistics and optimization algorithms in such a way to better explore the combinatorial search space and to increase the performance of the approaches. To this purpose we propose two methods: (i) Model Based Ant Colony Design and (ii) Naïve Bayes Ant Colony Optimization. We test the performance of the two proposed solutions on a simulation study and we apply the novel techniques on an appplication in the field of Enzyme Engineering and Design.
