Layout optimization and Sustainable development of waste water networks with the use of heuristic algorithms: The Luxemburgish case
Creators: name: Broukos, Pantelis
Publisher: name: Imperial College London
Year: 2020

description: Fresh water tends to increasingly comprise a scarcity today both in arid or demographically boosted regions of the world such as large and smaller cities. On this basis, research is directed towards minimization of fresh water supply into a Waste Water Network Topology (WWNT) and maximizing water re-use. This might be composed of a cluster of agents which have certain demands for fresh water as well as waste water dependent on their daily uses and living profiles. This work is divided into two parts. In the first part, different waste water flows within a reference building unit i.e. a typical household of four (4) occupants is simulated. This type of building represents a major part of the total building stock in Luxembourg. In its first part the present study attempts to examine the optimized fresh and waste water flow pathways between water using units of the building. Between water flows two domestic treatment units are adopted. The simulation of above mentioned system is attempted by adopting different algorithm methods such as the Sequential Quadratic Programming (SQP), the interior point and meta-heuristic optimization algorithms such as the Genetic Algorithms (GA’s).Suitable computational platform tools such as MATLAB and GAMS are incorporated. A comparison study on the most efficient approach is then realized on the single household unit by developing four (4) different mathematical model formulation versions. The second part of this study comprises simulation and development of the Waste Water Network Grid (WWNG) in the upscale level, such as the neighborhood level within or outside the urban context. This model encompasses all possible land uses and different kinds of buildings of different use envelopes thus demands. This range of units includes mainly building stock, agricultural and infrastructure of the tertiary sector. Integration of above mentioned model to the existing WWNG will enhance attempts to more closely reach the optimum points. The use of appropriate mathematical programming methods for the upscale level, will take place. Increased uncertainties within the built model will be attempted to be tackled by developing linear programming techniques and suitable assumptions without distorting initial condition largely. Assumptions are then drawn on the efficiency of the adopted method an additional essential task is the minimization of the overall infrastructure and network cost, which may in turn give rise to corresponding reduced waste effluents discharge off the proposed network. The case study comprises selected rural and semi-rural areas zone districts of similar living profiles outside the City of Luxembourg. Therefore a clustering of end users of similar demand will be attempted. Possible redesign of an optimized WWNG comprises a vital need within the context of large scale demographic growth of urban environments today.

description: We show that the truncated simplex Hilbert transform enjoys some cancellation in the sense that its norm grows sublinearly in the number of scales retained in the truncation. This extends the recent result by Tao on cancellation for the multilinear Hilbert transform. Our main tool is the Hilbert space regularity lemma due to Gowers, which enables a very short proof.

description: Abstract Background A wide range of diverse and inconsistent terminology exists in the field of knowledge translation. This limits the conduct of evidence syntheses, impedes communication and collaboration, and undermines knowledge translation of research findings in diverse settings. Improving uniformity of terminology could help address these challenges. In 2012, we convened an international working group to explore the idea of developing a common terminology and an overarching framework for knowledge translation interventions. Findings Methods included identifying and summarizing existing frameworks, mapping together a subset of those frameworks, and convening a multi-disciplinary group to begin working toward consensus. The group considered four potential approaches to creating a simplified framework: melding existing taxonomies, creating a framework of intervention mechanisms rather than intervention strategies, using a consensus process to expand one of the existing models/frameworks used by the group, or developing a new consensus framework. Conclusions The work group elected to draft a new, simplified consensus framework of interventions to promote and integrate evidence into health practices, systems and policies. The framework will include four key components: strategies and techniques (active ingredients), how they function (causal mechanisms), how they are delivered (mode of delivery), and what they aim to change (intended targets). The draft framework needs to be further developed by feedback and consultation with the research community and tested for usefulness through application and evaluation.

description: There is a number of different factors and data that require knowledge and responsibilities in the requalification and reorganization of a hospital building system. For the process to be successful and for its full implementation, there must be an inter-operation between this information and knowledge. This paper aims at contributing to this process by illustrating the experience of a multidisciplinary research laboratory consisting of architects belonging to the technological area, and computer/biomedical engineers, who defined and prepared a set of tools for an effective management of structural assets by using the “Policlinico di Careggi” hospital of Florence, that can be a reference for other similar contexts

description: We have analyzed XMM-Newton observations of the high energy peaked blazar, PKS 2155-304, made on 24 May 2002 in the 0.3 - 10 keV X-ray band. These observations display a mini-flare, a nearly constant flux period and a strong flux increase. We performed a time-resolved spectral study of the data, by dividing the data into eight segments. We fitted the data with a power-law and a broken power-law model, and in some of the segments we found a noticeable spectral flattening of the source's spectrum below 10 keV. We also performed time-resolved cross-correlation analyses and detected significant hard and soft lags (for the first time in a single observation of this source) during the first and last parts of the observation, respectively. Our analysis of the spectra, the variations of photon-index with flux as well as the correlation and lags between the harder and softer X-ray bands indicate that both the particle acceleration and synchrotron cooling processes make an important contribution to the emission from this blazar. The hard lags indicate a variable acceleration process. We also estimated the magnetic field value using the soft lags. The value of the magnetic field is consistent with the values derived from the broad-band SED modeling of this source.

Electrode, electrocatalyst and electrolyte development for hybrid redox flow batteries
Creators: name: Simon, Benedict Arthur
Publisher: name: Imperial College London
Year: 2022

description: The development of new electrochemical devices and their subsequent widespread adoption alongside our energy grids is critical to support the incoming wave of renewable energy generation and the transition to net zero. Hybrid redox flow batteries are a promising alternative energy storage technology that could ultimately provide inexpensive and sustainable large scale energy storage solutions compared to their lithium-based counterparts. Technological improvements rely on improved understanding of the processes occurring in these devices. This thesis focuses on three aspects essential to all electrochemical devices – the electrode, electrocatalyst and electrolyte. First, electrochemical and tomographic imaging analyses are combined to understand the effect of electrode microstructure properties on the performance of a non-aqueous redox flow battery. With the help of a one dimensional model, mass-transfer coefficients are gathered from the experimentally determined polarisation curves and affirm the results positively linking electrode permeability to overall cell performance. Second, the synthesis and optimisation of a multifunctional, nitrogen-doped carbon based electrocatalyst is outlined. The active site of the electrocatalyst is examined using a suite of physical characterisation techniques and is shown to have intriguing versatility across the pH spectrum towards catalysing both oxygen and hydrogen fundamental reactions. This catalyst is then tested, with a variety of success, in two fuel cell devices and, alongside the electrodes tested in the first section, in a hydrogen-manganese hybrid redox flow battery. Finally, the aqueous liquid electrolyte involved in this hybrid redox flow battery is scrutinised. Two in-operando analytical techniques are developed, providing improved handles on real-time solution-phase manganese species concentration in the electrolyte. The production of solid manganese oxides significantly alters solution equilibria making the deconvolution of electrochemical and adjacent, simultaneous chemical processes complex.
Measures of organizational characteristics associated with adoption and/or implementation of innovations: A systematic review

description: Abstract Background This paper identifies and describes measures of constructs relevant to the adoption or implementation of innovations (i.e., new policies, programs or practices) at the organizational-level. This work is intended to advance the field of dissemination and implementation research by aiding scientists in the identification of existing measures and highlighting methodological issues that require additional attention. Methods We searched for published studies (1973–2013) in 11 bibliographic databases for quantitative, empirical studies that presented outcome data related to adoption and/or implementation of an innovation. Included studies had to assess latent constructs related to the “inner setting” of the organization, as defined by the Consolidated Framework for Implementation Research. Results Of the 76 studies included, most (86%) were cross sectional and nearly half (49%) were conducted in health care settings. Nearly half (46%) involved implementation of evidence-based or “best practice” strategies; roughly a quarter (26%) examined use of new technologies. Primary outcomes most often assessed were innovation implementation (57%) and adoption (34%); while 4% of included studies assessed both outcomes. There was wide variability in conceptual and operational definitions of organizational constructs. The two most frequently assessed constructs included “organizational climate” and “readiness for implementation.” More than half (55%) of the studies did not articulate an organizational theory or conceptual framework guiding the inquiry; about a third (34%) referenced Diffusion of Innovations theory. Overall, only 46% of articles reported psychometric properties of measures assessing latent organizational characteristics. Of these, 94% (33/35) described reliability and 71% (25/35) reported on validity. Conclusions The lack of clarity associated with construct definitions, inconsistent use of theory, absence of standardized reporting criteria for implementation research, and the fact that few measures have demonstrated reliability or validity were among the limitations highlighted in our review. Given these findings, we recommend that increased attention be devoted toward the development or refinement of measures using common psychometric standards. In addition, there is a need for measure development and testing across diverse settings, among diverse population samples, and for a variety of types of innovations.

description: In the present study, a series of planar poly(p-phenylene) (PPP) oligomers with n phenyl rings (n = 1 - 20), designated as n-PP, are taken as finite-size models of the narrowest armchair graphene nanoribbons with hydrogen passivation. The singlet-triplet energy gap, vertical ionization potential, vertical electron affinity, fundamental gap, optical gap, and exciton binding energy of n-PP are calculated using Kohn-Sham density functional theory and time-dependent density functional theory with various exchange-correlation density functionals. The ground state of n-PP is shown to be singlet for all the chain lengths studied. In contrast to the lowest singlet state (i.e., the ground state), the lowest triplet state and the ground states of the cation and anion of n-PP are found to exhibit some multi-reference character. Overall, the electronic and optical properties of n-PP obtained from the omegaB97 and omegaB97X functionals are in excellent agreement with the available experimental data.

description: Abstract Background The long-acting muscarinic antagonist (LAMA) umeclidinium (UMEC) and the combination of UMEC with the long-acting β2-agonist (LABA) vilanterol (UMEC/VI) are approved maintenance treatments for chronic obstructive pulmonary disease (COPD) in the US and EU. They are not indicated for the treatment of asthma. Methods In this 52-week, double-blind, placebo-controlled, parallel-group safety study (GSK study DB2113359; NCT01316887), patients were randomized 2:2:1 to UMEC/VI 125/25 mcg, UMEC 125 mcg, or placebo. Study endpoints included adverse events (AEs), clinical chemistry and hematology parameters, vital signs, 12-lead, and 24-hour Holter electrocardiograms. COPD exacerbations and rescue medication use were assessed as safety parameters; lung function was also evaluated. Results The incidence of on-treatment AEs, serious AEs (SAEs), and drug-related AEs was similar between treatment groups (AEs: 52–58%; SAEs: 6–7%; drug-related AEs: 12–13%). Headache was the most common AE in each treatment group (8–11%). AEs associated with the LAMA and LABA pharmacologic classes occurred at a low incidence across treatment groups. No clinically meaningful effects on vital signs or laboratory assessments were reported for active treatments versus placebo. The incidences of atrial arrhythmias with UMEC/VI 125/25 mcg were similar to placebo; for UMEC 125 mcg, the incidences of ectopic supraventricular beats, sustained supraventricular tachycardia, and ectopic supraventricular rhythm were ≥2% greater than placebo. With active treatments, COPD exacerbations were fewer (13–15% of patients reporting ≥1 exacerbation) and on average less rescue medication was required (1.6–2.2 puffs/day) versus placebo (24% reporting ≥1 exacerbation, 2.6 puffs/day). Both active treatments improved lung function versus placebo. Conclusion UMEC/VI 125/25 mcg and UMEC 125 mcg were well tolerated over 12 months in patients with COPD.

Rectal indomethacin alone versus indomethacin and prophylactic pancreatic stent placement for preventing pancreatitis after ERCP: study protocol for a randomized controlled trial
Creators: name: Baron, Todd H
Publisher: name: BioMed Central
Year: 2016

description: Abstract Background The combination of prophylactic pancreatic stent placement (PSP) – a temporary plastic stent placed in the pancreatic duct – and rectal non-steroidal anti-inflammatory drugs (NSAIDs) is recommended for preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in high-risk cases. Preliminary data, however, suggest that PSP may be unnecessary if rectal NSAIDs are administered. Given the costs and potential risks of PSP, we aim to determine whether rectal indomethacin obviates the need for pancreatic stent placement in patients undergoing high-risk ERCP. Methods/Design The SVI (Stent vs. Indomethacin) trial is a comparative effectiveness, multicenter, randomized, double-blind, non-inferiority study of rectal indomethacin alone versus the combination of rectal indomethacin and PSP for preventing PEP in high-risk cases. One thousand four hundred and thirty subjects undergoing high-risk ERCP, in whom PSP is planned solely for PEP prevention, will be randomized to indomethacin alone or combination therapy. Those who are aware of study group assignment, including the endoscopist, will not be involved in the post-procedure care of the patient for at least 48 hours. Subjects will be assessed for PEP and its severity by a panel of independent and blinded adjudicators. Indomethacin alone will be declared non-inferior to combination therapy if the two-sided 95 % upper confidence bound of the treatment difference is less than 5 % between the two groups. Biological specimens will be obtained from trial participants and centrally banked. Discussion The SVI trial is designed to determine whether PSP remains necessary in the era of NSAIDs pharmacoprevention. The associated bio-repository will establish the groundwork for important scientific breakthrough. Trial registration NCT02476279, registered June 2015.

description: We examine transient circular dichroism spectroscopy (TRCD) as a technique to investigate signatures of exciton coherence dynamics under the influence of structured vibrational environments. We consider a pump-probe configuration with a linearly polarized pump and a circularly polarized probe, with a variable angle $θ$ between the two directions of propagation. In our theoretical formalism the signal is decomposed in chiral and achiral doorway and window functions. Using this formalism, we show that the chiral doorway component, which beats during the population time, can be isolated by comparing signals with different values of $θ$. As in the majority of time-resolved pump-probe spectroscopy, the overall TRCD response shows signatures of both excited and ground state dynamics. However, we demonstrate that the chiral doorway function has only a weak ground state contribution, which can generally be neglected if an impulsive pump pulse is used. These findings suggest that the pump-probe configuration of optical TRCD in the impulsive limit has the potential to unambiguously probe quantum coherence beating in the excited state. We present numerical results for theoretical signals in an example dimer system.

Availability of family planning services and quality of counseling by faith-based organizations: a three country comparative analysis
Creators: name: Barden-O'Fallon, Janine
Publisher: name: BioMed Central
Year: 2017

description: Abstract Background Faith-based organizations (FBOs) have a long history of providing health services in developing countries and are important contributors to healthcare systems. Support for the wellbeing of women, children, and families is evidenced through active participation in the field of family planning (FP). However, there is little quantitative evidence on the availability or quality of FP services by FBOs. Methods The descriptive analysis uses facility-level data collected through recent Service Provision Assessments in Malawi (2013–14), Kenya (2010), and Haiti (2012) to examine 11 indicators of FP service and method availability and nine indicators of comprehensive and quality counseling. The indicators include measures of FP service provision, method mix, method stock, the provision of accurate information, and the discussion of reproductive intentions, client’s questions/concerns, prevention of sexually transmitted infections, and return visits, among others. Pearson’s Chi-square test is used to assess the selected indicators by managing authority (FBO, public, and other private sector) to determine statistical equivalence. Results Results show that FBOs are less likely to offer FP services than other managing authorities (p < 0.05). For example, 69% of FBOs in Kenya offer FP services compared to 97% of public facilities and 83% of other private facilities. Offering long-acting or permanent methods in faith-based facilities is especially low (43% in Malawi, 29% in Kenya and 39% in Haiti). There were few statistically significant differences between the managing authorities in comprehensive and quality counseling indicators. Interestingly, Haitian FBOs often perform as well or better than public sector health facilities on counseling indicators, such as discussion of a return visit (79% of FBO providers vs. 68% of public sector providers) and discussion of client concerns/questions (52% vs. 49%, respectively). Conclusions Results from this analysis indicate that there is room for improvement in the availability of FP services by FBOs in these countries. Quality of counseling should be improved by all managing authorities in the three countries, as indicated by low overall coverage for practices such as ensuring confidentiality (22% in Malawi, 47% in Kenya and 12% in Haiti), discussion of sexually transmitted infections (18%, 25%, 17%, respectively), and providing services to youth (53%, 27%, 32%, respectively).

description: Using a grid of $\sim 2$ million elements ($Δz = 0.005$) adapted from COSMOS photometric redshift (photo-z) searches, we investigate the general properties of template-based photo-z likelihood surfaces. We find these surfaces are filled with numerous local minima and large degeneracies that generally confound rapid but "greedy" optimization schemes, even with additional stochastic sampling methods. In order to robustly and efficiently explore these surfaces, we develop BAD-Z [Brisk Annealing-Driven Redshifts (Z)], which combines ensemble Markov Chain Monte Carlo (MCMC) sampling with simulated annealing to sample arbitrarily large, pre-generated grids in approximately constant time. Using a mock catalog of 384,662 objects, we show BAD-Z samples $\sim 40$ times more efficiently compared to a brute-force counterpart while maintaining similar levels of accuracy. Our results represent first steps toward designing template-fitting photo-z approaches limited mainly by memory constraints rather than computation time.

Abiotic O$_{2}$ Levels on Planets around F, G, K, and M Stars: Possible False Positives for Life?

description: In the search for life on Earth-like planets around other stars, the first (and likely only) information will come from the spectroscopic characterization of the planet's atmosphere. Of the countless number of chemical species terrestrial life produces, only a few have the distinct spectral features and the necessary atmospheric abundance to be detectable. The easiest of these species to observe in Earth's atmosphere is O$_{2}$ (and its photochemical byproduct, O$_{3}$). But O$_{2}$ can also be produced abiotically by photolysis of CO$_{2}$, followed by recombination of O atoms with each other. CO is produced in stoichiometric proportions. Whether O$_{2}$ and CO can accumulate to appreciable concentrations depends on the ratio of far-UV to near-UV radiation coming from the planet's parent star and on what happens to these gases when they dissolve in a planet's oceans. Using a one-dimensional photochemical model, we demonstrate that O$_{2}$ derived from CO$_{2}$ photolysis should not accumulate to measurable concentrations on planets around F- and G-type stars. K-star, and especially M-star planets, however, may build up O$_{2}$ because of the low near-UV flux from their parent stars, in agreement with some previous studies. On such planets, a 'false positive' for life is possible if recombination of dissolved CO and O$_{2}$ in the oceans is slow and if other O$_{2}$ sinks (e.g., reduced volcanic gases or dissolved ferrous iron) are small. O$_{3}$, on the other hand, could be detectable at UV wavelengths ($λ$ < 300 nm) for a much broader range of boundary conditions and stellar types.

description: The empirical basis for the conceptualization of biographies of refugees living in Germany is shaped by life situation analyses that have been conducted on different age groups, on women and men, and on specific disadvantages due to disability or sexual orientation in several research projects implemented by the authors. The aim of the research program is to reflect the educational and social support system in light of these refugee biographies: On the one hand, the strategies with which the refugees try to cope with the difficult living conditions are reconstructed. The resilience revealed in these strategies is theorized as a survival habitus. On the other hand, we investigated how the professionals working in the education and support system perceive these life situations and take them into account to conceptually frame their work. The empirical materials shows that the professional habitus often cannot grasp the life situations of refugees, but remains trapped in the institutional logic of action. Possibilities are discussed as to how the necessary habitus sensitivity can be established in the academic training of social workers and anchored in the university curriculum.

Innocent, Guilty or Reluctant Midwife? On the Reciprocal Relevance of STS and Post-truth

description: The rise of post-truth has called into question STS, mostly in the defendant’s role. A critique from outside, such as Lee McIntyre’s, provides a debatable account of science deconstruction and its appropriation by “right-wing postmodernism”. Within STS, post-truth has revamped discussions on the implications of the symmetry principle, or elicited a reiteration of arguments for more inclusive generation of public facts. Steve Fuller stands out as a dissonant, more intriguing voice. He praises post-truth for triggering and expressing an emancipatory thrust against elites and an institutional rearrangement of science, and blames STS for being too shy with its midwifing role. However, he also underestimates the import of ongoing changes. The struggle over truth has shifted to an ontological level, raising doubts on optimistic views. If STS is relevant to post-truth, the vice versa also applies. Post-truth indicates that STS has to equip itself for a sociotechnical world ever-more distant from the one in which it has developed.

description: Abstract Background The proportion of extrapulmonary tuberculosis (EPTB) reported in the United States has been gradually increasing. HIV infection and foreign birth are increasingly associated with tuberculosis and understanding their effect on the clinical presentation of tuberculosis is important. Methods Case-control study of 6,124 persons with tuberculosis reported to the North Carolina Division of Public health from January 1, 1993 to December 31, 2006. Multivariate logistic regression was used to obtain adjusted odds ratios measuring the associations of foreign birth region and US born race/ethnicity, by HIV status, with EPTB. Results Among all patients with tuberculosis, 1,366 (22.3%) had EPTB, 563 (9.2%) were HIV co-infected, and 1,299 (21.2%) were foreign born. Among HIV negative patients, EPTB was associated with being foreign born (adjusted ORs 1.36 to 5.09, depending on region of birth) and with being US born, Black/African American (OR 1.84; 95% CI 1.42, 2.39). Among HIV infected patients, EPTB was associated with being US born, Black/African American (OR 2.60; 95% CI 1.83, 3.71) and with foreign birth in the Americas (OR 5.12; 95% CI 2.84, 9.23). Conclusion Foreign born tuberculosis cases were more likely to have EPTB than US born tuberculosis cases, even in the absence of HIV infection. Increasing proportions of foreign born and HIV-attributable tuberculosis cases in the United States will likely result in a sustained burden of EPTB. Further research is needed to explore why the occurrence and type of EPTB differs by region of birth and whether host genetic and/or bacterial variation can explain these differences in EPTB.

description: Modern wireless communication networks, particularly cellular networks utilize multiple antennas to improve the capacity and signal coverage. In these systems, typically an active transceiver is connected to each antenna. However, this one-to-one mapping between transceivers and antennas will dramatically increase the cost and complexity of a large phased antenna array system. In this paper, firstly we propose a \emph{partially adaptive} beamformer architecture where a reduced number of transceivers with a digital beamformer (DBF) is connected to an increased number of antennas through an RF beamforming network (RFBN). Then, based on the proposed architecture, we present a methodology to derive the minimum number of transceivers that are required for marco-cell and small-cell base stations, respectively. Subsequently, in order to achieve optimal beampatterns with given cellular standard requirements and RF operational constraints, we propose efficient algorithms to jointly design DBF and RFBN. Starting from the proposed algorithms, we specify generic microwave RFBNs for optimal marco-cell and small-cell networks. In order to verify the proposed approaches, we compare the performance of RFBN using simulations and anechoic chamber measurements. Experimental measurement results confirm the robustness and performance of the proposed hybrid DBF-RFBN concept eventually ensuring that theoretical multi-antenna capacity and coverage are achieved at a little incremental cost.
