description: Software ecosystems have gained a lot of attention in recent times. Industry and developers gather around technologies and collaborate to their advancement; when the boundaries of such an effort go beyond certain amount of projects, we are witnessing the appearance of Free/Libre and Open Source Software (FLOSS) ecosystems. In this chapter, we explore two aspects that contribute to a healthy ecosystem, related to the attraction (and detraction) and the death of ecosystems. To function and survive, ecosystems need to attract people, get them on-boarded and retain them. In Section One we explore possibilities with provocative research questions for attracting and detracting contributors (and users): the lifeblood of FLOSS ecosystems. Then in the Section Two, we focus on the death of systems, exploring some presumed to be dead systems and their state in the afterlife.

description: In the last four budget cycles, the Trump administration has proposed slashing funding for U.S. Environmental Protection Agency research programs. When Congress has refused, administration officials have sought to prevent, hide, and discredit research in other ways. They have been remarkably successful despite the existence of agency policies designed to protect researchers against political interference.

description: Τα  έξυπνα υλικά που χρησιμοποιούνται για την προστασία και την προφύλαξη των αρχιτεκτονικών επιφανειών, αποτελούν ένα ευρύ πεδίο μελέτης σήμερα. Ιδιαίτερο ενδιαφέρον παρουσιάζεται για τα υλικά που προσφέρουν υπερυδρόφοβες ιδιότητες και επιτρέπουν στις επιφάνειες να απομακρύνουν το νερό και είναι αυτοκαθαριζόμενες. Με αυτό τον τρόπο  προστατεύουν τα δομικά υλικά από φθορές που δημιουργούνται τόσο απο το νερό όσο και από την περιβαλλοντική και ατμοσφαιρική ρύπανση.
Το αντικείμενο της παρούσας ερευνητικής εργασίας, που εκπονήθηκε στο εργαστήριο Υλικών Πολιτιστικής Κληρονομιάς και Σύγχρονης Δόμησης, υπό την επίβλεψη της καθηγήτριας κυρίας Νόνης-Παγώνας Μαραβελάκη, αφορά στην εύρεση και την μελέτη καινοτόμων υπέρ-υδροφοβικών νανοσύνθετων υλικών. Τα υλικά αυτά παράγονται με την μέθοδο λύματος-πηκτής (Sol-Gel), μια μέθοδο που χρησιμοποιείται για την παραγωγή υδροφοβικών και υπερ-υδροφοβικών υμενίων, κατάλληλα για την αδιαβροχοποίηση διαφόρων υλικών. Αρχικά έγιναν 17 πειραματικές συνθέσεις υδρόφοβων και υπερ-υδρόφοβων υλικών, που αξιολογήθηκαν ως προς την προστατευτική τους ικανότητα σε διαφορετικά υποστρώματα (λίθοι, μάρμαρα, τσιμέντα), μερικά από τα οποία έχουν χρησιμοποιηθεί για την κατασκευή μνημείων πολιτισμού. Έπειτα, η μελέτη εστιάστηκε σε ένα συγκεκριμένο δομικά υπόστρωμα (αλφάς), προκειμένου να βρεθεί η βέλτιστή σύνθεση των προστατευτικών υλικών για το συγκεκριμένο υπόστρωμα και να αξιολογηθεί ως προς τις ιδιότητες του. Εξασφαλίσαμε με αυτό τον τρόπο μια σειρά καινοτόμων νανοσύνθετων υλικών, με υπερ-υδροφοβικές ιδιότητες, τα οποία δίνουν γωνίες επαφής μεταξύ 130 και 160 μοιρών, ενώ διαθέτουν λίγες έως και καθόλου μικρορωγμές (cracking). Από το σύνολο των συνθέσεων επιλέχθηκαν για πρόταση οι 5 που έδωσαν γωνίες επαφής μεγαλύτερες των 150 μοιρών, ενώ οι υπόλοιπες παρουσιάζονται στο παράρτημα της εργασίας. Συνοψίζοντας, δημιουργήσαμε μια σειρά μη τοξικών, οικολογικών προστατευτικών υλικών, που είναι συμβατά με διάφορα υποστρώματα, ενώ απαιτούν απλή και μη ενεργοβόρα διαδικασία παραγωγής.

description: "Science is science and facts are facts. My administration will ensure that there will be total [scientific] transparency and accountability without political bias.” That was the promise made in September 2016 by then-candidate Donald Trump when asked how he would protect federal scientists from political interference in their work. Since taking office, however, President Trump has led a concerted effort to undermine federal scientific research, particularly in areas where research findings contradict his own views or undermine the basis of his deregulatory agenda. That effort is documented in the Silencing Science Tracker, an online database that records anti-science actions taken by the federal government. Drawing on three-and-a-half years of tracker data, this Comment analyzes the Trump Administration’s evolving war on science and shows how it is changing the way federal agencies perform, use, and communicate scientific research. We focus primarily on climate science, which has been the subject of particularly fierce attacks under President Trump, though he has also targeted other areas. His actions could have long-lasting consequences, damaging the role of science in regulation for years to come.

description: Η παρούσα διπλωματική εργασία αφορά την πολεοδομική ανάπλαση και διάσωση της παλιάς πόλης του Χαλεπιού μετά τον πολυετή εμφύλιο πόλεμο. Η παλιά πόλη του Χαλεπιού αποτελεί μια από τις αρχαιότερες συνεχόμενα κατοικημένες πόλεις στον κόσμο, με πληθυσμό πριν από τον πόλεμο να εκτιμάται στις 100 χιλιάδες κατοίκους. Στο σύνολο του το Χαλέπι αποτελεί την δεύτερη μεγαλύτερη πόλη της Συρίας, με πληθυσμό πριν το πόλεμο να εκτιμάται στα 3 εκατομμύρια κατοίκους ενώ αποτελούσε σημαντικό εμπορικό κόμβο.
Η διπλωματική εργασία χωρίζεται σε τρία μέρη. Το πρώτο μέρος αποτελεί την ιστορική ανάλυση της παλιάς πόλης πριν από τον πόλεμο και παραθέτει πληροφορίες σχετικά με τα δημογραφικά χαρακτηριστικά, την εξέλιξη και τις τυπολογίες του αστικού ιστού, τα δίκτυα, τις χρήσεις γης, τους όρους δόμησης, το δομημένο-αδόμητο και τους δημόσιους χώρους. Στο δεύτερο μέρος παρουσιάζεται και αναλύεται η κατάσταση της παλιάς πόλης κατά την διάρκεια και μετά την λήξη του πολέμου και δίνεται έμφαση στις καταστροφές τόσο των κτιρίων όσο και των δικτύων. Το τρίτο μέρος περιλαμβάνει την πρόταση για την Αναζωογόνηση της παλιάς πόλης του Χαλεπιού έχοντας μια ανθρωποκεντρική προσέγγιση, δίνοντας δηλαδή προτεραιότητα στους κατοίκους της πόλης και ωθώντας τους να συμμετέχουν στο έργο ανοικοδόμησης της. Η πρόταση περιλαμβάνει σημειακές επεμβάσεις προκειμένου η πόλη να καταστεί βιώσιμη για τον αριθμό των κατοίκων που προβλέπεται να έχει μέχρι και το έτος 2025. Συγκεκριμένα, προτείνονται επεμβάσεις σε επίπεδο χρήσεων γης, όρων δόμησης, δικτύων, δημοσίων χώρων και χώρων πρασίνου. Δεδομένου ότι ο αριθμός των κατοίκων έχει αρχίσει να αυξάνεται σταδιακά με τη λήξη του πολέμου, ορισμένες χρήσεις γης έχουν την δυνατότητα μεταβολής στον χρόνο ανάλογα με τις εκάστοτε ανάγκες. Τέλος, προτείνονται δύο χώροι πρασίνου, εκτός των ορίων την παλιάς πόλης, που μπορούν να χρησιμοποιηθούν ως προσωρινοί καταυλισμοί των κατοίκων που θα επιστρέψουν στην πόλη.

description: Several researchers as well as high-profile female athletes have recently challenged the longstanding view that pregnancy/motherhood mark the termination of an elite athlete's career in sport. While these conversations have sparked change concerning the degree to which pregnant/parenting athletes are accepted within the sport industry, elite athletes continue to face discriminatory policies and practices as they navigate parenthood alongside their elite athletic pursuits. My thesis is presented in the publishable papers format. In my first paper, I used new masculinities theory, community-based participatory research, and semi structured interviews to explore the experiences of 10 elite/international and world-class male athletes (9 fathers, 1 expectant father) and the impact of children on their athletic careers. Through critical discourse analysis, I found that fatherhood both improves and impedes elite athlete-fathers' athletic performance. In my second paper, I used feminist poststructuralist theory, feminist participatory action research, and semi-structured interviews to explore the perspectives of 21 pregnant and parenting elite/international and world-class athletes (11 women, 10 men) on the developing degree of acceptance of parenthood in elite athletics. Through critical discourse analysis, I identified that, despite considerable recent advancements, there is still a need for increased acceptance of pregnant/parenting athletes. Taken together, these two papers advance understandings regarding athletes' perspectives on the current shifts surrounding parenthood and athletics. Further, the recognition of fathers' involvement in childcare underscores how male athletes represent an untapped resource for allyship for female athletes. My findings also call for significant continued change and action to better support pregnant/parenting athletes.

description: We introduce Resilient Multiple Choice Learning (rMCL), an extension of the MCL approach for conditional distribution estimation in regression settings where multiple targets may be sampled for each training input. Multiple Choice Learning is a simple framework to tackle multimodal density estimation, using the Winner-Takes-All (WTA) loss for a set of hypotheses. In regression settings, the existing MCL variants focus on merging the hypotheses, thereby eventually sacrificing the diversity of the predictions. In contrast, our method relies on a novel learned scoring scheme underpinned by a mathematical framework based on Voronoi tessellations of the output space, from which we can derive a probabilistic interpretation. After empirically validating rMCL with experiments on synthetic data, we further assess its merits on the sound source localization problem, demonstrating its practical usefulness and the relevance of its interpretation.

description: We report a transport study on Pd$_3$In$_7$ which displays multiple Dirac type-II nodes in its electronic dispersion. Pd$_3$In$_7$ is characterized by low residual resistivities and high mobilities, which are consistent with Dirac-like quasiparticles. For an applied magnetic field $(μ_{\text{0}} H)$ having a non-zero component along the electrical current, we find a large, positive, and linear in $μ_{\text{0}} H$ longitudinal magnetoresistivity (LMR). The sign of the LMR and its linear dependence deviate from the behavior reported for the chiral-anomaly-driven LMR in Weyl semimetals. Interestingly, such anomalous LMR is consistent with predictions for the role of the anomaly in type-II Weyl semimetals. In contrast, the transverse or conventional magnetoresistivity (CMR for electric fields $\textbf{E} \bot μ_{\text{0}} \textbf{H}$) is large and positive, increasing by $10^3-10^4$ \% as a function of $μ_{\text{0}}H$ while following an anomalous, angle-dependent power law $ρ_{\text{xx}}\propto (μ_{\text{0}}H)^n$ with $n(θ) \leq 1$. The order of magnitude of the CMR, and its anomalous power-law, is explained in terms of uncompensated electron and hole-like Fermi surfaces characterized by anisotropic carrier scattering likely due to the lack of Lorentz invariance.

description: We present an implementation of time-dependent density-functional theory (TDDFT) in the linear response formalism enabling the calculation of low energy optical absorption spectra for large molecules and nanostructures. The method avoids any explicit reference to canonical representations of either occupied or virtual Kohn-Sham states and thus achieves linear-scaling computational effort with system size. In contrast to conventional localised orbital formulations, where a single set of localised functions is used to span the occupied and unoccupied state manifold, we make use of two sets of in situ optimised localised orbitals, one for the occupied and one for the unoccupied space. This double representation approach avoids known problems of spanning the space of unoccupied Kohn-Sham states with a minimal set of localised orbitals optimised for the occupied space, while the in situ optimisation procedure allows for efficient calculations with a minimal number of functions. The method is applied to a number of medium sized organic molecules and a good agreement with traditional TDDFT methods is observed. Furthermore, linear scaling of computational cost with system size is demonstrated on a system of carbon nanotubes.

description: Occultations provide indirect sensitivity to the number density of small Kuiper Belt objects (KBOs) too faint to directly detect telescopically. We present results from the Caltech HI-speed Multicolor camERA (CHIMERA) survey with the Palomar Hale Telescope, which monitored stars over the central 5'x5' of the M22 globular cluster along the ecliptic plane for serendipitous occultations by kilometer-scale KBOs over 63 hr across 24 nights at a 33 Hz frame rate simultaneously in i' and g'. We adapted dense-field photometry and occultation template fitting techniques to this dataset, finding a 95% confidence upper limit on the occultation rate corresponding to an ecliptic sky density of <10^7 deg^-2 of >1 km diameter classical KBOs. We discuss a few of the occultation-like light curve signatures at the edge of the sensitivity limit responsible for setting the upper bounds, and their likely nonviability as true occultations.

Stakeholder-supported restoration suitability modelling for oyster reefs in Sydney, Australia
Creators: name: Howie, Alice

Subjects: Other education not elsewhere classified

description: Oyster reefs are one of the most imperiled marine habitats on earth, and are functionally extinct in Australia. Their ability to maintain ecosystem health and provide ecosystem services is highly valued, and there is growing initiative to restore oyster reefs, worldwide. Habitat suitability modelling has emerged as a powerful tool to guide site selection, a crucial component of restoration. Such models often use bio-physical parameters, but rarely consider conflicting estuarine uses or stakeholder-support, which are increasingly important in spatially complex, urbanised estuaries. This thesis took a holistic approach to suitability modelling, utilising available biological and physical spatial data and local stakeholder knowledge, to develop a stakeholder-supported restoration suitability model. Suitability models targeted native (Saccostrea glomerata and Ostrea angasi) oysters, whilst limiting proliferation of non-native Crassostrea gigas, and were produced for two highly urbanised estuaries, Sydney Harbour and Botany Bay in Sydney, Australia. When habitat suitability, estuarine conflicts, ecological connectivity and stakeholder-support were considered, 0.4-3.3% of each estuary was assessed as highly suitable for native oyster reef restoration. This holistic, data-driven approach to suitability modelling will guide pilot studies and site prioritisation, and may serve as a framework for future restoration modelling endeavours in other urbanised estuaries.

Justification for proposed resurrection of the step 0 GPHS module for Interstellar Probe
Creators: name: Yale Chang
Publisher: name: F1000 Research Limited
Year: 2023

description: The Interstellar Probe mission was initially proposed to travel 1000 astronomical units (AUs) in 50 years, after launching in the 2030s. In a later mission concept review, this was reduced to 400 AUs. The spacecraft uses Next Generation Radioisotope Thermoelectric Generators (RTGs), which are similar to General Purpose Heat Source (GPHS)-RTGs, to provide electrical power to the onboard scientific and communications equipment. The highest possible specific power (power per unit mass) of the RTG is desired. The current plan is for these RTGs to use the latest design of the GPHS module, called the Step 2 module. It would have a specific power of 4.7 Welectric/kg [Beginning of Life (BOL) 276 Welectric for 16 modules]. This briefing presents justification for a proposal to instead use the original design Step 0 module, which is smaller and lighter than the Step 2 module, in an RTG case of the same length. In doing so, a higher specific power for the RTG of 5.3 Welectric/kg [BOL 300 Welectric for 18 modules] can be achieved. The Step 0 GPHS module has been qualified for survivability to accidental impacts, and orbital decay and shallow angle reentries. It is important to note that this is the GPHS-RTG design flown on the Cassini mission.

description: Click-through rate (CTR) prediction aims to predict the probability that the user will click an item, which has been one of the key tasks in online recommender and advertising systems. In such systems, rich user behavior (viz. long- and short-term) has been proved to be of great value in capturing user interests. Both industry and academy have paid much attention to this topic and propose different approaches to modeling with long-term and short-term user behavior data. But there are still some unresolved issues. More specially, (1) rule and truncation based methods to extract information from long-term behavior are easy to cause information loss, and (2) single feedback behavior regardless of scenario to extract information from short-term behavior lead to information confusion and noise. To fill this gap, we propose a Graph based Long-term and Short-term interest Model, termed GLSM. It consists of a multi-interest graph structure for capturing long-term user behavior, a multi-scenario heterogeneous sequence model for modeling short-term information, then an adaptive fusion mechanism to fused information from long-term and short-term behaviors. Comprehensive experiments on real-world datasets, GLSM achieved SOTA score on offline metrics. At the same time, the GLSM algorithm has been deployed in our industrial application, bringing 4.9% CTR and 4.3% GMV lift, which is significant to the business.

description: We present a novel Pharmacokinetic/Pharmacodynamic (PK/PD) model for the induction phase of anesthesia, incorporating the $ψ$-Caputo fractional derivative. By employing the Picard iterative process, we derive a solution for a nonhomogeneous $ψ$-Caputo fractional system to characterize the dynamical behavior of the drugs distribution within a patient's body during the anesthesia process. To explore the dynamics of the fractional anesthesia model, we perform numerical analysis on solutions involving various functions of $ψ$ and fractional orders. All numerical simulations are conducted using the MATLAB computing environment. Our results suggest that the $ψ$ functions and the fractional order of differentiation have an important role in the modeling of individual-specific characteristics, taking into account the complex interplay between drug concentration and its effect on the human body. This innovative model serves to advance the understanding of personalized drug responses during anesthesia, paving the way for more precise and tailored approaches to anesthetic drug administration.

description: We show that, in principle, a slowly evolving gravitationally collapsing perfect fluid cloud can asymptotically settle to a static spherically symmetric equilibrium configuration with a naked singularity at the center. We consider one such asymptotic final configuration with a finite outer radius, and construct a toy model in which it is matched to a Schwarzschild exterior geometry. We examine the properties of circular orbits in this model. We then investigate observational signatures of a thermal accretion disk in this spacetime, comparing them with the signatures expected for a disk around a black hole of the same mass. Several notable differences emerge. A disk around the naked singularity is much more luminous than one around an equivalent black hole. Also, the disk around the naked singularity has a spectrum with a high frequency power law segment that carries a major fraction of the total luminosity. Thus, at least some naked singularities can, in principle, be distinguished observationally from black holes of the same mass. We discuss possible implications of these results.

description: We show that a topologically trivial zero bias conductance peak (of height 4e^2/h) is produced in semiconductor-superconductor hybrid nanowires due to a suppressed pair potential and/or an excess Zeeman field at the ends of the heterostructure, both of which can occur in experiments. The zero bias peak (ZBP) (a) appears above a threshold parallel bulk Zeeman field, (b) is stable for a range of bulk field before splitting, (c) disappears with rotation of the bulk Zeeman field, and, (d) is robust to weak disorder fluctuations. The ZBPs from the nanowire ends are also expected to produce splitting oscillations with the applied field similar to those from Majorana fermions. We find that the only unambiguous way to distinguish these trivial ZBPs (of height 4e^2/h) from those arising from Majorana fermions (of height 2e^2/h) is by comparing the (zero temperature) peak height and/or through an interference experiment.

description: Antibiotic resistance (AR) remains one of the leading global health challenges, mostly implicated in disease-related deaths. The Enterobacteriaceae-producing metallo-β-lactamases (MBLs) are critically involved in AR pathogenesis through Zn-dependent catalytic destruction of β-lactam antibiotics, yet with limited successful clinical inhibitors. The efficacy of relevant broad-spectrum β-lactams including imipenem and meropenem are seriously challenged by their susceptibility to the Zn-dependent carbapenemase hydrolysis, as such, searching for alternatives remains imperative. In this study, computational molecular modelling and virtual screening methods were extensively applied to identify new putative Zn-sensitive broad-spectrum inhibitors of MBLs, specifically imipenemase-1 (IMP-1) from the IBScreen database. Three ligands, STOCK3S-30154, STOCK3S-30418 and STOCK3S-30514 selectively displayed stronger binding interactions with the enzymes compared to reference inhibitors, imipenem and meropenem. For instance, the ligands showed molecular docking scores of −9.450, −8.005 and −10.159 kcal/mol, and MM-GBSA values of −40.404, −31.902 and −33.680 kcal/mol respectively against the IMP-1. Whereas, imipenem and meropenem showed docking scores of −9.038 and −10.875 kcal/mol, and MM-GBSA of −31.184 and −32.330 kcal/mol respectively against the enzyme. The ligands demonstrated good thermodynamic stability and compactness in complexes with IMP-1 throughout the 100 ns molecular dynamics (MD) trajectories. Interestingly, their binding affinities and stabilities were significantly affected in contacts with the remodelled Zn-deficient IMP-1, indicating sensitivity to the carbapenemase active Zn site, however, with non-β-lactam scaffolds, tenable to resist catalytic hydrolysis. They displayed ideal drug-like ADMET properties, thus, representing putative Zn-sensitive non-β-lactam inhibitors of IMP-1 amenable for further experimental studies. Communicated by Ramaswamy H.

description: The conformable double ARA decomposition approach is presented in this current study to solve one-dimensional regular and singular conformable functional Burger's equations. We investigate the conformable double ARA transform's definition, existence requirements, and some basic properties. In this study, we introduce a novel interesting method that combines the double ARA transform with Adomian's decomposition method, in order to find the precise solutions of some nonlinear fractional problems. Moreover, we use the new approach to solve Burgers' equations for both regular and singular conformable fractional coupled systems. We also provide several instances to demonstrate the usefulness of the current study. Mathematica software has been used to get numerical results.

description: The accretion of matter onto black holes and neutron stars often leads to the launching of outflows that can greatly affect the environments surrounding the compact object. In supermassive black holes, these outflows can even be powerful enough to dictate the evolution of the entire host galaxy, and yet, to date, we do not understand how these so-called accretion disk winds are launched - whether by radiation pressure, magnetic forces, thermal irradiation, or a combination thereof. An important means of studying disk winds produced near the central compact object is through X-ray absorption line spectroscopy, which allows us to probe outflow properties along a single line of sight, but usually provides little information about the global 3D disk wind structure that is vital for understanding the launching mechanism and total wind energy budget. Here, we study Hercules X-1, a unique, nearly edge-on X-ray binary with a warped accretion disk precessing with a period of about 35 days. This disk precession results in changing sightlines towards the neutron star, through the ionized outflow. We perform time-resolved X-ray spectroscopy over the precession phase and detect a strong decrease in the wind column density by three orders of magnitude as our sightline progressively samples the wind at greater heights above the accretion disk. The wind becomes clumpier as it rises upwards and expands away from the neutron star. Modelling the warped disk shape, we create a 2D map of wind properties. This unique measurement of the vertical structure of an accretion disk wind allows direct comparisons to 3D global simulations to reveal the outflow launching mechanism.

description: This work is a summation of Divya Rajasekharan and Arielle Feder’s 2020 summer project of capturing the coronal shape of the uterus in late pregnancy for patient-specific parametric models in the Myers Soft Tissue Lab at Columbia University. In order to simulate the mechanics of birth, accurate models of reproductive anatomy must be acquired. With MRI images costly to obtain and not routinely taken during pregnancy, wide implementation of a patient-specific modeling framework of pregnancy must be based on 2D ultrasound images. Previously, our lab has used a parametric modeling framework based on 2D ultrasound images that assumes an ellipsoidal coronal uterine shape. However, this shape does not accurately capture anatomy in late gestation. Therefore, we investigate utilization of two additional modeling methods based on observations from solid models of the uterus and cervix from segmented MRI images of late gestation pregnancy. The first modeling method is based off the same measurements taken from 2D ultrasound, with additional assumptions about coronal shape derived from MRI images. The second modeling method uses numerous uterine diameter and wall thickness measurements from MRI. All models are compared using finite element analysis with simplistic loading conditions for 5 patients. It was found that uterine wall thickness throughout the uterine body has a significant effect on the magnitude and pattern of stress and stretch. It is also noted that direction of principle strains is consistent across all models. For future simulations of birth, we will develop a solid modeling method that incorporates aspects of both tested models.

description: This work is a summation of Divya Rajasekharan and Arielle Feder’s 2020 summer project of parametrically modeling the pelvic bone and vaginal canal in the Myers Soft Tissue Lab at Columbia University. In order to simulate the mechanics of birth, accurate models of reproductive anatomy must be acquired, including the pelvic bone and vaginal canal. The vaginal canal modeling method is based off of measurements from existing literature, capturing the vaginal axis and transverse width. Though currently employing patient averages, we have built the model such that patient-specific measurements of the vaginal canal can be used in the future. The pelvic bone modeling method introduces simplifications that capture the structures relevant to fetal head decent, while also capturing patient-specific pelvic inlet shape. Thus, the pelvic bone is reduced to a ring that can capture most pelvic inlet shapes and solid body to represent the sacrum. In the future, these structures will be implemented into a finite element analysis simulation of birth and their effect on the mechanics of delivery explored.

description: In a randomized study with longitudinal data on a mediator and outcome, estimating the direct effect of treatment on the outcome at a particular time requires adjusting for confounding of the association between the outcome and all preceding instances of the mediator. When the confounders are themselves affected by treatment, standard regression adjustment is prone to severe bias. In contrast, G-estimation requires less stringent assumptions than path analysis using SEM to unbiasedly estimate the direct effect even in linear settings. In this article, we propose a G-estimation method to estimate the controlled direct effect of treatment on the outcome, by adapting existing G-estimation methods for time-varying treatments without mediators. The proposed method can accommodate continuous and noncontinuous mediators, and requires no models for the confounders. Unbiased estimation only requires correctly specifying a mean model for either the mediator or the outcome. The method is further extended to settings where the mediator or outcome, or both, are latent, and generalizes existing methods for single measurement occasions of the mediator and outcome to longitudinal data on the mediator and outcome. The methods are utilized to assess the effects of an intervention on physical activity that is possibly mediated by motivation to exercise in a randomized study.

description: The plant Sida rhombifolia has been used to remove lead ions from aqueous solution as a biosorbent. The biosorption ability tests were carried out in an equilibrium batch to investigate the effects of contact time (10-120 min), temperature (30-60°C), initial metal ion concentration (10-90 mg/L), agitation speed (50-250 rpm), biomass dosage (50-500 mg), and retention volume on the biosorption capacity (25-150 mL). The thermodynamic parameters revealed that biosorption was an endothermic and spontaneous method. The kinetic data were well represented by the pseudo second-order model. The equilibrium data suits better with the Temkin model, according to the isotherm studies. The results of the present investigation indicate that the Sida rhombifolia has a potential for use in removing lead from aqueous solutions.

description: In intervention studies having multiple outcomes, researchers often use a series of univariate tests (e.g., ANOVAs) to assess group mean differences. Previous research found that this approach properly controls Type I error and generally provides greater power compared to MANOVA, especially under realistic effect size and correlation combinations. However, when group differences are assessed for a specific outcome, these procedures are strictly univariate and do not consider the outcome correlations, which may be problematic with missing outcome data. Linear mixed or multivariate multilevel models (MVMMs), implemented with maximum likelihood estimation, present an alternative analysis option where outcome correlations are taken into account when specific group mean differences are estimated. In this study, we use simulation methods to compare the performance of separate independent samples t tests estimated with ordinary least squares and analogous t tests from MVMMs to assess two-group mean differences with multiple outcomes under small sample and missingness conditions. Study results indicated that a MVMM implemented with restricted maximum likelihood estimation combined with the Kenward–Roger correction had the best performance. Therefore, for intervention studies with small N and normally distributed multivariate outcomes, the Kenward–Roger procedure is recommended over traditional methods and conventional MVMM analyses, particularly with incomplete data.

description: Σήμερα υπάρχει ένα αυξανόμενο ενδιαφέρον για την επιτάχυνση εξειδικευμένου υπολογισμού. Το ζήτημα προσεγγίζεται είτε με καινοτόμες αρχιτεκτονικές, προσαρμοσμένες στην επίλυση συγκεκριμένης κατηγορίας προβλημάτων, είτε με την χρήση επιταχυντών υλικού. Η δεύτερη κατηγορία αντιπροσωπεύεται κυρίως από τις FPGAs λόγω της ικανότητάς τους να αναπροσαρμόζονται και επαναχρησιμοποιούνται σε διαφορετικά υπολογιστικά προβλήματα. Η Μερική Αναδιάταξη επεκτείνει την ευελιξία των FPGA με το να επιτρέπει τον επαναπρογραμματισμό τμήματος του υλικού κατά τον χρόνο εκτέλεσης και χωρίς διακοπή της λειτουργίας του συστήματος. Αυτή η τεχνολογία καθιστά εφικτή την δημιουργία ενός συστήματος που θα προσφέρει πολλαπλούς ανεξάρτητους επιταχυντές υλικού, οι οποίοι θα μπορούν να φορτώνονται κατά βούληση ανάλογα με τις υπολογιστικές ανάγκες.
	Η παρούσα μεταπτυχιακή εργασία υλοποιεί ένα τέτοιο σύστημα χρησιμοποιώντας τα Zynq FPGA SoC της Xilinx. Η εργασία αποτελείται από τα εξής τέσσερα τμήματα:
	α) Υλοποιήση του συστήματος σε FPGA.
	β) Λογισμικό πυρήνα λειτουργικού συστήματος Linux για την διαχείριση του υλικού.
	γ) Βιβλιοθήκη συστήματος για εύκολη πρόσβση από εφαρμογές χρήστη.
	δ) Εφαρμογή επίδειξης με επιταχυντές που υλοποιούν ψηφιακή επεξεργασία εικόνας.
Η υλοποίηση προσφέρει διαφάνεια μεταξύ συστήματος και χρήστη, εκμεταλλεύεται τις ευκαιρίες για παραλληλισμό στην πρόσβαση μνήμης και παρέχει ευελιξία στη δημιουργία διατάξεων επιταχυντών και διαμόρφωσης μνήμης.
