description: With the increasing application of machine learning in high-stake decision-making problems, potential algorithmic bias towards people from certain social groups poses negative impacts on individuals and our society at large. In the real-world scenario, many such problems involve positive and unlabeled data such as medical diagnosis, criminal risk assessment and recommender systems. For instance, in medical diagnosis, only the diagnosed diseases will be recorded (positive) while others will not (unlabeled). Despite the large amount of existing work on fairness-aware machine learning in the (semi-)supervised and unsupervised settings, the fairness issue is largely under-explored in the aforementioned Positive and Unlabeled Learning (PUL) context, where it is usually more severe. In this paper, to alleviate this tension, we propose a fairness-aware PUL method named FairPUL. In particular, for binary classification over individuals from two populations, we aim to achieve similar true positive rates and false positive rates in both populations as our fairness metric. Based on the analysis of the optimal fair classifier for PUL, we design a model-agnostic post-processing framework, leveraging both the positive examples and unlabeled ones. Our framework is proven to be statistically consistent in terms of both the classification error and the fairness metric. Experiments on the synthetic and real-world data sets demonstrate that our framework outperforms state-of-the-art in both PUL and fair classification.
Total energy performance - the importance of daylight efficient solar shadings

description: The energy performance building directive (EPBD) from the European commission states, amongst other issues, that electrical lighting has to be included the evaluation of the energy performance of non-domestic office buildings. This is new and it is affecting practitioners throughout Europe. In an effort to design a low energy office, data for a building was implemented in the Danish national calculation method. External blinds was added and showed a decrease in the total energy consumption. An integrated dynamic energy and daylight simulation of an office room were then performed. The result of the simulation showed that if external blinds were introduced, the total energy consumption increased. According to the detailed simulation, the blinds did remove the cooling load but introduced an increased need for electrical lighting by shutting out daylight. This is a new realization in practice and may change the way buildings are designed. External blinds are still an efficient way of reducing cooling load if they also are designed properly in terms of daylight. But the national tool for evaluation of the energy performance of new buildings is not capable of including such a level of shading design details. There is therefore a distinct need for simulation tools which includes an integrated evaluation of the daylight performance of blinds and control of electrical lighting in the calculation of energy performance. Such a tool should i.e. use hour values in stead monthly mean values as weather data. This paper presents such a tool and suggests a simplified method for including the daylight performance of blinds in the national calculation methods.

Publisher: name: 8th Symposium on Building Physics in the Nordic Countries
Year: 2008

description: Temperatures of exterior surfaces are affected by various heat fluxes. Beside the heat fluxes due to heat conduction through the building component and heat convection from the surrounding air, radiation effects are important as well. Usually only the short-wave radiation heating up the component’s surface during the day is taken into account. The long-wave, thermal emission of the component’s surface is often neglected. Realistic temperature conditions on the component’s surface can not be computed very well in this way.
It is shown how the balance of all relevant radiation components can be evaluated which lead to an increase or decrease of the surface temperature. Validation of the WUFI® results by comparison with  measurements at the IBP test site demonstrates generally good agreement between measurement and calculation. Hygrothermal performance on exterior surfaces depending on radiation effects can now be investigated.

description: CAR T cell therapy reliably results in positive effect on patients with hematologic malignancy but shows less efficacy in solid tumor treatments due to limited trafficking and tumor infiltration, intensive CAR T-related toxicities and antigen scape. So, a cell delivery platform is required to overcome these limitations and improve efficacy towards solid tumor treatments. Here, we have introduced a biodegradable implantable polymeric cell delivery device that delivers CAR T cells to tumor site in a prolong and sustained manner. These milliammeter-size GelMA toroidal spiral particles (TSPs) presenting an internal void volume for high-capacity cell loading, are used as a co-delivery system of MSLN CAR T cell and IL-2, a growth factor essential for cell expansion and proliferation. A sustained cytokine and cell release out of these particles has achieved while maintaining a high cell proliferation and viability in vitro. In a NSG mouse model of breast cancer and colorectal carcinoma, we found that CAR T cells can successfully migrate from these particles to the solid tumor and control tumor outgrowth more effectively than systemic and peri-tumoral administration of CAR T cells. So, biodegradable GelMA TSPs may improve anti-tumor efficacy of CAR T cell therapy for solid tumor treatment.

description: The paper analyses the heat balance of various types of earth-sheltered buildings, which may become a novel approach to sustainable dwellings.

Earth-sheltered buildings may be simply described as a concrete construction built on a soil surface level and next covered with soil. Due to large mass and thermal capacity of soil it reacts more slowely to changes of its surface temperature and the annual variations are reduced with depth. It causes the soil temperature at a certain depth to be higher than that of surrounding air in the winter and lower in the summer. If this fact is taken into account when designing a house, one may achieve lower heat losses through a building’s envelope to the surrounding, by covering the building with soil.

In the article, results of heat balance simulations for several types of earth sheltered houses with different soil thickness covering a roof are presented and compared with the heat balance of a traditional above-ground building. Annual heat balance is done in EnergyPlus software which is combined with simulations of soil temperature distribution in FlexPDE.

The results indicate earth-sheltered buildings as better than the above-ground ones regarding the energy efficiency. Nowadays, when energy demands become more strict every year, this approach may become one of the ways of lowering the energy consumption in dwellings.
Alternative methods of evaluating the airtightness of building envelopes

description: The airtightness of the building envelope is a very important factor in determining the energy use of a building, and thus its environmental impact and running costs.  Good airtightness is also important for the quality of a building's internal environment and for its moisture resistance.

Unfortunately, it is all too seldom that the airtightness of building envelopes is followed up and verified.  In Sweden, such measurements are mainly made when the building envelope in its entirety has been completed, but it is technically difficult to correct any defects at this stage.  Corrective actions may require the removal of materials that have been erected which, at a late and sensitive stage of the construction process, is expensive in terms of materials wastage, labour and completion delays.

The parties involved (developers, consultants and contractors) need other methods for describing and evaluating airtightness:  methods that can make it easier to monitor airtightness of more building projects, and which can be carried out at an early stage of the construction process.  Finding air leaks at an early stage means that they can be dealt with in time, at a reasonable cost, and that the building will be sufficiently airtight when it is completed.
Cardiac Myocyte and Fibroblast Structure and Function is Affected by Transthyretin Amyloid Deposition

description: Age-related wild type transthyretin amyloidosis (wtATTR) is characterized by systemic deposition of amyloidogenic fibrils of misfolded transthyretin (TTR) in the connective tissue of many organs. In the heart this leads to broad cardiac dysfunction and is increasingly understood to be a significant cause of age-related heart failure with preserved ejection fraction (HFpEF). The first hypothesis tested is that underlying TTR fibrils disrupt cardiac fibroblast homeostasis which may contribute to fibrosis progression. Primary cardiac fibroblasts had altered cytoskeletal and nuclear architecture when cultured on TTR fibrils, with decreased number of focal adhesions and lower attachment to fabricated micropost substrata. Additionally, deposition of TTR caused cardiac fibroblasts to have increased rates of migration and proliferation. Further, RNA-seq and proteomic analysis showed that cardiac fibroblasts cultured on TTR fibrils had upregulation of immune-related pathways and secretion of proinflammatory cytokines. Taken together, data indicates that TTR fibril deposition alters cardiac fibroblast behavior for immune cell recruitment, along with increased rates of migration and proliferation, which are hallmarks of a fibrosis-promoting fibroblast phenotype. The second hypothesis tested is that TTR deposited in the in vitro model disrupts cardiac myocyte calcium handling, the contraction profile, sarcomere architecture, and cell adhesion complexes. Neonatal rat ventricular myocytes (NRVMs) and adult mouse atrial myocytes exhibited prolonged calcium transients when cultured on TTR fibrils. Additionally, NRVMs cultured on TTR fibrils had decreased expression of the gap junction protein connexin 43 and significantly impaired intercellular connectivity as determined by FRAP. TTR deposition also led to decreased expression of mechanical junction proteins N-cadherin and vinculin. Both NRVMs and human iPSC-derived cardiomyocytes, when cultured on soft hydrogels covered by TTR fibrils, had decreased contractile parameters and force production as observed by traction force microscopy. Finally, NRVMs grown on TTR fibrils had loss of sarcomeric α-actinin with a corresponding increase of ubiquitin localization to the sarcomere. As therapies for wtATTR are cost-prohibitive and only slow disease progression, better understanding of cellular maladaptation in the presence of TTR may elucidate novel therapeutic targets.

description: The monotonic heating regime method for determination of thermal diffusivity is based on the analysis of an unsteady-state (stabilised) thermal process characterised by an independence of the space-time temperature distribution on initial conditions. At the first kind of the monotonic regime a sample of simple geometry is heated / cooled at constant ambient temperature. The determination of thermal diffusivity requires determination the rate of a temperature change and simultaneous determination the first eigenvalue. The eigenvalue is found from a relationship between the synchronous temperatures measured at the surface and at the middle of specimen, which is expressed by eigenfunctions in the analytical solution.
According to a characteristic equation the first eigenvalue is a function of the Biot number defined by surface heat transfer coefficient and thermal conductivity of an analysed material. Knowing the surface heat transfer coefficient and the first eigenvalue the thermal conductivity can be determined. The surface heat transport coefficient during the monotonic regime can be determined by the continuous measurement of long-wave radiation heat flow and the photoelectric measurement of the air refractive index gradient in a boundary layer. The obtained eigenvalues and corresponding surface heat transfer coefficient values enable to determine thermal conductivity of the analysed sample together with its thermal diffusivity, during a monotonic heating regime.
title: Towards the total synthesis of amphidinolides C and F

Publisher: name: University of Glasgow
Year: 2016
Subjects: subject: total synthesis.

description: The amphidinolides are marine macrolides extracted from dinoflagellates of the genus Amphidinium. To date, 37 amphidinolides have been isolated and identified, most of them possessing cytotoxicity against human cancer cell lines. Among these, amphidinolides C, F, C2 and C3 represent synthetic targets of interest owing to their scarcity, structural complexity and promising biological activities.
This thesis describes the work realised towards the total synthesis of amphidinolides C and F, with a focus on the different strategies investigated and the key fragments synthesised. In the first approach, the C18−C29 fragment of amphidinolide F was prepared using an intramolecular etherification of an epoxide under acidic catalysis to produce the 2,5-trans-disubstituted tetrahydrofuran ring featured in the natural product. Unfortunately, dithiane alkylation with the C1−C17 iodide counterpart generated the desired coupling product in low yield. A second approach proposing to build the C17−C18 bond by a silicon-tethered RCM proved unsuccessful, because the requisite diene could not be obtained. It was then envisioned to form the C18−C19 bond by displacement of a triflate with an alkyne and install the ketone at C18 by a protoborylation/oxidation sequence. To this end, the C19−C29 triflate precursor was synthesised. Displeasingly, the C1−C18 alkyne counterpart (work by Dr Filippo Romiti) could not be prepared and coupling of the two fragments was not attempted. In the latest approach, the C10−C29 fragment of amphidinolide F was obtained employing a boron-mediated aldol condensation and a dithiane alkylation to form the C13−C14 and C18−C19 bonds. Several endgame strategies were examined including the successful Yamaguchi esterification of the C13-epi C10−C29 fragment and the C1−C9 acid. A challenging Stille crosscoupling was then effected to close the macrocycle but only yielded the desired macrolactone in trace amounts after global desilylation.

description: Thermal conductivity of dry porous building materials is determined by configuration of their solid and liquid phases. Particular components and pore volume fractions can have different configurations in a material volume. For the ideally continuous high conductivity components fractions with the discrete low conductivity components the macroscopic transport coefficient can be obtained by summation the thermal conductivities of all particular components fractions proportionally to their relative volume portions. In case of the discrete high conductivity components in the ideally continuous low conductivity volume fractions a serial configuration of the components can be applied. These two models represent the simplest - Wiener bounds of thermal conductivity. In practice the models for evaluation of effective thermal conductivity of porous composite materials are based on the combination of parallel and serial configuration of particular phases and components. The problem of empiric factor of each model is to determine the adequate portion of the serial and parallel components depending on their microstructure.
Thermal conductivity of dry porous building materials can be expressed by Wiener model of the configuration of high and low conductivity components, in which the degree of the dispersion of continuous phases is expressed by by the power functions of their volume fractions. The exponents express the degree of deviations of real component volumes from an ideal continuity supposed in Wiener model.
The exponents include fractal dimension of particular components and correspond to a character of the configuration of particular high conductivity components and low conductivity components in the materials. The relationships between the exponents and fractal dimensions of various materials were analysed. The fractal dimensions were determined from microscopy pictures of the considered materials by a box counting method.

Method for integrated design of low energy buildings with high quality indoor environment

Publisher: name: 8th Symposium on Building Physics in the Nordic Countries
Year: 2008

description: The topic of this paper is a suggestion for an integrated design method which allows building designers to make consequence-conscious design decisions in terms of energy performance and indoor environment at the very early stage of the building design process. Energy performance and indoor environment have due to new increased regulatory demands become decisive design parameters in the building design process. In order to comply with the increased regulatory demands, we present an integrated design method which argues that the design of buildings must start on room level rather than total building level. The proposed method starts with the establishment of design goals, including goals regarding energy performance and indoor environment, followed by a building physical analysis of performance-decisive parameters. This analysis is used to establish a space of solutions from which the designer can obtain an overview of the consequences of their design decisions in terms of energy performance and indoor environment. Based on the space of solutions the designer can set up possible room designs which fulfil the design goals prior to the total building form giving. The possible room designs can be combined in to a number of overall building designs from which the best performing proposal can be selected and optimised. In this way the final building design will have an energy performance and indoor environment inherited from the room designs, thus fulfilling design goals in terms of energy performance and indoor environment. The method has been tested and evaluated in courses in integrated design at the Technical University of Denmark. Furthermore the method has been tested in real building projects. Based on the experiences gained through these tests, the proposed method has been adjusted and refined in order to become the preferred method for integrated design of low energy buildings with high quality indoor environment.

description: Wind speed conditions on the tracks of outdoor athletics stadiums can determine whether a record is confirmed or denied. A 2 m/s tail wind is currently the limit above which new records are considered invalid. The measurement of wind speed inside the stadium however only occurs at one position and does not take into account the variability of the wind speed conditions across and along the track. The goal of this research is to analyse the relationship between sport stadium geometry and stadium wind flow patterns, with the final aim to arrive at guidelines to optimize outdoor sport stadium geometry as well as guidelines for wind speed measurements for the correction of sprint time results.

The study focuses on the Koning Boudewijn stadium in Brussels (Belgium), in which full-scale wind flow measurements were made for a duration of several weeks. The measurement data are processed to gain time-averaged wind speeds and wind directions which are used in order to create a clear overview of the wind patterns inside the stadium. The measurements show large fluctuations in wind speed and wind direction inside the stadium indicating that the flow is highly unsteady.

The validation of the CFD model is performed by comparing the CFD results with the full-scale measurements. A comprehensive CFD model of the Koning Boudewijn stadium is constructed with a computational grid based on grid sensitivity analysis. The numerical results show the importance of relatively small objects in the model of the Koning Boudewijn stadium. These objects include ground level differences around the stadium, porous fences and trees. The numerical results show a good prediction of the overall complexity of the wind flow patterns, when these objects are included in the model.

Furthermore an investigation is made concerning the use of transient calculations. The need for this investigation is driven by the large fluctuations in wind speed and wind direction inside the stadium found in the measurements. Preliminary simulations of wind flow around ground surfaced cubes show the complexity of wind flow patterns when time-dependency is introduced. This complexity is caused by vortex shedding from the three-dimensional cube which can be partially the reason for the fluctuations found in the measurements of the wind flow inside the Koning Boudewijn stadium

description: Indoor air quality (IAQ) is one of the most important factors for the welfare of the society. Indoor air quality is a complex result of different simultaneous affecting factors. Numerical and experimental simulation studies about the moisture transfer between structures and indoor and outdoor air spaces are relatively well known, but the transfer of volatile organic compounds (VOCs), particles and microbes from or through the building envelope to indoor air have been studied insufficiently. A new laboratory device,  the IAQ simulator chamber, has been designed and constructed to study the effect of  building materials and structures on the IAQ. The IAQ simulator device can be used to study structure components between controlled ‘indoor’ and ‘outdoor’ air spaces, which brings new perspective to the research when compared to the applicability of conventional emission test chambers. The test structure or the outdoor air may contain materials having biological growth that are impurity sources for air. The effect of these sources on the indoor air can be studied under different heat, humidity and air pressure difference conditions.  The  measurements include evaluation of moisture content of materials, humidity, temperature, air leakage through the building structure, air pressure difference, analyses of indoor air quality (Volatile organic compounds VOC, particles and microbes).

This paper presents  a short study, where Microbial VOC and new molecular biological techniques were applied to detect and quantify microbes on building materials and in air samples using small conventional emission chambers and the IAQ simulator device. The IAQ simulator device offers a new tool to study the complicated causal connections of building structures, materials and unexpected exposure to water and microbes, especially during the use of the buildings. The results can be used together with a whole building hygrothermal analysis to give ideas to a risk assessment of the building performance under realistic climatic loads. Also renovation concepts needed to protect the indoor air from emissions of polluted building materials can be studied.

description: New guidelines have been developed and trialled in Australia to assist urban stormwater managers to assess options for projects that aim to improve urban waterway health. These guidelines help users to examine the financial, ecological and social dimensions of projects (i.e. the so-called \342\200\230triple-bottom-line\342\200\231). Features of the assessment process described in the guidelines include use of multi criteria analysis, input from technical experts as well as non-technical stakeholders, and provision of three alternative levels of assessment to suit stormwater managers with differing needs and resources. This paper firstly provides a background to the new guidelines and triple-bottom-line assessment. The assessment methodology promoted in the new guidelines is then briefly summarised. This methodology is compared and contrasted with European guidelines from the \342\200\230SWARD\342\200\231 project that have been primarily developed for assessing the relative sustainability of options involving urban water supply and sewerage assets. Finally, the paper discusses how assessment methodologies that evaluate the financial, ecological and social dimensions of projects can, under some circumstances, be used to evaluate the relative progress of options for urban water management on a journey towards the widely pursued, but vaguely defined goal of \342\200\230sustainable development\342\200\231.

description: Absence of large-scale labeled data in the practitioner's target domain can be a bottleneck to applying machine learning algorithms in practice. Transfer learning is a popular strategy for leveraging additional data to improve the downstream performance, but finding the most relevant data to transfer from can be challenging. Neural Data Server (NDS), a search engine that recommends relevant data for a given downstream task, has been previously proposed to address this problem. NDS uses a mixture of experts trained on data sources to estimate similarity between each source and the downstream task. Thus, the computational cost to each user grows with the number of sources. To address these issues, we propose Scalable Neural Data Server (SNDS), a large-scale search engine that can theoretically index thousands of datasets to serve relevant ML data to end users. SNDS trains the mixture of experts on intermediary datasets during initialization, and represents both data sources and downstream tasks by their proximity to the intermediary datasets. As such, computational cost incurred by SNDS users remains fixed as new datasets are added to the server. We validate SNDS on a plethora of real world tasks and find that data recommended by SNDS improves downstream task performance over baselines. We also demonstrate the scalability of SNDS by showing its ability to select relevant data for transfer outside of the natural image setting.

description: Background: The move toward telemedicine has markedly accelerated with the COVID-19 pandemic. As faculty learn the skills necessary to provide anesthesia services on a virtual platform, the specialty must ensure residents are instructed effectively. We therefore created a pilot curriculum for postgraduate year-2 (PGY2) anesthesiology residents focusing on telemedicine instruction. Methods: Our pilot curriculum consisted of a virtual didactic teaching session and a simulated encounter with a standardized patient (SP) on a telemedicine platform. Formative feedback was provided from both a faculty member and the patient using a checklist based on the American Medical Association Telehealth Visit Etiquette Checklist and the American Board of Anesthesiology Applied Examination Objective Structured Clinical Examination content outline. Residents completed surveys assessing their perceptions of the effectiveness and helpfulness of the didactic session and simulated encounter, as well as the mental workload of the encounter. Results: Twelve PGY2 anesthesiology residents participated in this study. All considered the didactic session to be effective for teaching virtual pre-operative assessment and conveying best practices. They indicated that the SP encounter was of greater value (more effective and helpful) than the didactic session. In assessing mental workload, residents perceived the encounter as demanding, but they felt successful in accomplishing the encounter and did not feel rushed. Faculty and the SP indicated that the checklist guided them in providing clear and useful formative feedback. Conclusion: Training programs must embrace telemedicine and train residents on best practices when utilizing this tool. Standardized patient encounters can enhance training by safely facilitating practice.

description: This paper reports recent developments in oil trapping and oil biodegrading systems in pervious pavements and in infiltration systems used in conjunction with non-pervious surfaces. The advances made in the technology and operation of pervious surfaces fitted with an integrated oil water separator will be described. This involves a newly developed, floating mat system which serves to interact with any oil which, in the event of a large spill, passes through the initial oil retaining structures of a pervious pavement or other form of infiltration system. It also provides the ideal surface upon which the oil degrading organisms will thrive. The ability of these enhanced systems to produce a diverse biodegrading bacterial/fungal community is reported. A further study will report a comparison of biodegradation of new and used mineral oil trapped on these structures. The second area of research reported will be associated with a novel oil separating system designed to be either coupled closely to an infiltrating filter trench which can be used in conjunction with impervious surfaces or to direct the water back under an impermeable surface for further treatment, retention and attenuation of flow. This system was shown to be highly effective in removing hydrocarbons and has the advantage that it can be used as a retrofit solution to allow disconnection of existing impervious surfaces without exposing groundwater to contamination.

description: The flow capacity of urban stormwater drainage channels in major cities of India are gradually being reduced due to increased quantities of solid waste being introduced into these systems. During low flows, the solid waste forms deposits within these open drainage channels. These must be regularly cleaned to ensure that the drains function at an optimal hydraulic capacity in order to limit overflows. This places a significant burden on the operators of these systems. The erosion of deposits during high intensity rainfall, combined with flooding can release significant amounts of pollutants into areas adjacent to these channels. This can have a high economic and social impact as these areas have experienced a high level of development in recent years. One of the ways to minimize deposits, and reduce the management burden, is to provide invert traps in the drainage system at pre-determined locations to reduce the deposits and concentrate the solid waste at a smaller number of known locations . Once full, these can then be emptied within a planned programme of work. This paper describes the initial sediment retention studies of various configurations of invert trap using Computation Fluid Dynamics (CFD) modeling. A 2-D CFD model, using the FLUENT software, was implemented to solve the continuous flow phase and to estimate the flow patterns. This study has examined three different trap configurations with different types of particle type over a range of six discharges (low, medium and high). Early results indicate that the trap performance is sensitive to the discharge and the trap configuration. Further work is in progress to determine the optimal shape for trapping efficiency of solids under Indian conditions.

description: Pervious pavements have made an important contribution to stormwater quality improvements in sustainable urban drainage systems, particularly as part of a treatment train approach. In Spain however this approach has hardly been addressed. This paper outlines the emerging research in a collaboration between UK and Spanish Universities aimed at establishing a research infrastructure to allow the study of pervious pavements to be carried out taking into account local conditions in the northwest of Spain. Parallel with the development of locally-appropriate porous pavement structures a biological study dealing with the hydrocarbon degrading efficiency is taking place. Experiments are reported utilising different locally available surfaces and sub-base materials in which microorganisms are introduced from a variety of contaminated sites to act as an inoculum. In addition to effluent analysis aimed at measuring the degree of hydrocarbon retention/degradation, experiments will be reported on the physical characteristic of the different materials used. This research addresses the influence, not only of the different surface and sub-base materials but also of the different types of geosynthetics used. It is intended that this research will establish criteria for the further development of a design for hydrocarbon-degrading pervious pavement structures in Spain.
