description: We discuss the character of states near the Fermi level in Mn doped GaAs, as revealed by a survey of dc transport and optical studies over a wide range of Mn concentrations. A thermally activated valence band contribution to dc transport, a mid-infrared peak at energy hbar omega approx 200 meV in the ac- conductivity, and the hot photoluminescence spectra indicate the presence of an impurity band in low doped (<<1% Mn) insulating GaAs:Mn materials. Consistent with the implications of this picture, both the impurity band ionization energy inferred from the dc transport and the position of the mid-infrared peak move to lower energies and the peak broadens with increasing Mn concentration. In metallic materials with > 2% doping, no traces of Mn-related activated contribution can be identified in dc-transport, suggesting that the impurity band has merged with the valence band. No discrepancies with this perception are found when analyzing optical measurements in the high-doped GaAs:Mn. A higher energy (hbar omega approx 250 meV) mid-infrared feature which appears in the metallic samples is associated with inter-valence band transitions. Its red-shift with increased doping can be interpreted as a consequence of increased screening which narrows the localized-state valence-band tails and weakens higher energy transition amplitudes. Our examination of the dc and ac transport characteristics of GaAs:Mn is accompanied by comparisons with its shallow acceptor counterparts, confirming the disordered valence band picture of high-doped metallic GaAs:Mn material.

Open Scholarship in Practice: Presentation of a Set of Use Cases Collected on Behalf of Knowledge Exchange
Creators: name: Franck, Gwen
Publisher: name: Zenodo
Year: 2019

description: On behalf of Knowledge Exchange, the author has collected use cases based on interviews conducted with a large variety of stakeholders.With this report, the author hopes to give an overview of the dynamics in the field of open scholarship services and hopes to inspire researchers, entrepreneurs and other parties to make the move towards open science – by improving general understanding of the economical mechanics that are at play in the business of open scholarship.

Interviewees are part of organisations, businesses or institutions offering or working with one or more open scholarship related services and tools. In a candid manner, the interviewees discuss topics such as their business model(s), sustainability and scalability (if applicable), the influence of open science policy making on their activities, their ideas on the role of (non)commercial entities in the field of open access publishing, licensing choices, and their views on the future of the services they offer and about open scholarship in general.

Especially relevant for the LIBER conference is how the majority of interviewees talks about their interaction with research libraries and how these relations can spur or, in some cases, deter innovation in the field of Open Scholarship.

Interviewees include CEO’s and directors of leading open science service providers such as Mark Hahnel from Figshare, Sarah Jones from DCC, Heather Piwowar from Impactstory, Tim Smith from CERN/Zenodo, Martin Paul Eve from Open Libraries of Humanities, Stephanie Dawson from ScienceOpen and Jadranka Stojanovski from HRCAK.

The report is expected to be published in February 2018 and is expected to contain between 12 and 15 use cases.

description: Mesoporous silica nanoparticles (MSNs) are promising drug nanocarriers for infection treatment. Many investigations have focused on evaluating the capacity of MSNs to encapsulate antibiotics and release them in a controlled fashion. However, little attention has been paid to determine the antibiotic doses released from these nanosystems that are effective against biofilm during the entire release time. Herein, we report a systematic and quantitative study of the direct effect of the antibiotic-cargo released from MSNs on Gram-positive and Gram-negative bacterial biofilms. Levofloxacin (LVX), gentamicin (GM) and rifampin (RIF) were separately loaded into pure-silica and amino-modified MSNs. This accounts for the versatility of these nanosystems since they were able to load and release different antibiotic molecules of diverse chemical nature. Biological activity curves of the released antibiotic were determined for both bacterial strains, which allowed to calculate the active doses that are effective against bacterial biofilms. Furthermore, in vitro biocompatibility assays on osteoblast-like cells were carried out at different periods of times. Albeit a slight decrease in cell viability was observed at the very initial stage, due to the initial burst antibiotic release, the biocompatibility of these nanosystems is evidenced since a recovery of cell viability was achieved after 72 h of assay. Biological activity curves for GM released from MSNs exhibited sustained patterns and antibiotic doses in the 2-6 μg/mL range up to 100 h, which were not enough to eradicate biofilm. In the case of LVX and RIF first-order kinetics featuring an initial burst effect followed by a sustained release above the MIC up to 96 h were observed. Such doses reduced by 99.9% bacterial biofilm and remained active up to 72 h with no emergence of bacterial resistance.

description: Let $V$ be the set of real common solutions to $F = (f_1, \ldots, f_s)$ in $\mathbb{R}[x_1, \ldots, x_n]$ and $D$ be the maximum total degree of the $f_i$'s. We design an algorithm which on input $F$ computes the dimension of $V$. Letting $L$ be the evaluation complexity of $F$ and $s=1$, it runs using $O^\sim \big (L D^{n(d+3)+1}\big )$ arithmetic operations in $\mathbb{Q}$ and at most $D^{n(d+1)}$ isolations of real roots of polynomials of degree at most $D^n$. Our algorithm depends on the real geometry of $V$; its practical behavior is more governed by the number of topology changes in the fibers of some well-chosen maps. Hence, the above worst-case bounds are rarely reached in practice, the factor $D^{nd}$ being in general much lower on practical examples. We report on an implementation showing its ability to solve problems which were out of reach of the state-of-the-art implementations.

description: Reducing motion of particles to a two-dimensional potential problem, we show that there are stable circular orbits around a squashed Kaluza-Klein black hole with a spherical horizon and multi-Kaluza-Klein black holes with two spherical horizons in five dimensions. For a single horizon, we show analytically that the radius of an innermost stable circular orbit monotonically depends on the size of an extra dimension. For two horizons, the radius of an innermost stable circular orbit depends on the separation between two black holes besides the size of an extra dimension. More precisely, the set of the stationary points of the potential is composed of two branches. For a large separation, stable circular orbits exist on the two branches regardless of the size of an extra dimension, and in particular, on one branch, the set of stable circular orbits is connected for the small extra dimension but has two disconnected parts for the large extra dimension. For a small separation, only on one branch it exists, and the radius of an innermost stable circular orbit monotonically increases with an extra-dimension size.

description: Excitation energy transfer is crucially involved in a variety of systems. During the process, the non-Condon vibronic coupling and the surrounding solvent interaction may synergetically play important roles. In this work, we study the correlated vibration-solvent influences on the non-Condon exciton spectroscopy. Statistical analysis is elaborated for the overall vibration-plus-solvent environmental effects. Analytic solutions are derived for the linear absorption of monomer systems. General simulations are accurately carried out via the dissipaton-equation-of-motion approach. The resulted spectra in either the linear absorption or strong field regime clearly demonstrate the coherence enhancement due to the synergetic vibration-solvent correlation.

description: The position and momentum information entropies of $D$-dimensional quantum systems with central potentials, such as the isotropic harmonic oscillator and the hydrogen atom, depend on the entropies of the (hyper)spherical harmonics. In turn, these entropies are expressed in terms of the entropies of the Gegenbauer (ultraspherical) polynomials $C_n^{(λ)}(x)$, the parameter $λ$ being either an integer or a half-integer number. Up to now, however, the exact analytical expression of the entropy of Gegenbauer polynomials of arbitrary degree $n$ has only been obtained for the particular values of the parameter $λ=0,1,2$. Here we present a novel approach to the evaluation of the information entropy of Gegenbauer polynomials, which makes use of trigonometric representations for these polynomials and complex integration techniques. Using this method, we are able to find the analytical expression of the entropy for arbitrary values of both $n$ and $λ\in\mathbb{N}$.

description: In this paper, we study feedback linearization problems for nonlinear differential-algebraic control systems (DACSs). We consider two kinds of feedback equivalences, namely, the external feedback equivalence, which is defined (locally) on the whole generalized state space, and the internal feedback equivalence, which is defined on the locally maximal controlled invariant submanifold (i.e., on the set where solutions exist). Necessary and sufficient conditions are given for the locally internal and the locally external feedback linearizability of DACSs with the help of a notion called the explicitation with driving variables, which attaches a class of ordinary differential equation control systems (ODECSs) to a given DACS. We show that the feedback linearizability of a DACS is closely related to the involutivity of the linearizability distributions of the explicitation systems. Finally, we apply our results of feedback linearization of DACSs to an academical example and a constrained mechanical system.

Making Open Science transparent: the Bibliolabs project
Creators: name: Bretel, Henri

description: Big Research Universities tend to have increasingly diversified sources of income. The threat is that for researchers, every funder having their own requirements and evaluation rules makes it hard and stressful to comply with each of them, and for citizens it often fosters opacity, preventing people to easily trace the funding schemes of science.

One important source of income for research in recent years has been European funding, including ERC grants and projects in European Commission Framework Programs. Research funded by Europe offers an opportunity to enhance transparency towards citizen because Open Science is strongly incentivized, but it does not help researchers face the problem of diversity and opacity of funding sources and evaluation, since it adds the ‘ethics’ and ‘open science’ layers to the already intricate traditional bibliometrics used by supervisors.

At the moment, our university offers to help any researcher that asks for it to prepare their application, obtain ERC grants and, once obtained, comply with the demands of these kinds of funding, like research data management and making their research open.

By our project, we add a new, European facet to our bibliographic database, aiming to make use of the Open Data ecosystem to effectively support all researchers and not only those who ask for it. We combine three types of data that are available in our French context:

	Open data (OpenAIRE, CORDIS from Europe, national references like RNSR, IDRef and HAL, European and non-European patent databases),
	Private data from traditional bibliometric companies (Scopus and Web of Science),
	Self-gathered data from our European projects support team.

This way, we will first automatically discover any grant or project in which one of our researchers might be involved by crawling CORDIS database, then contact them and get an answer on whether or not they need help on complying to Open science and research data management policies. Then we will be able to follow each project and see all the types of impacts European funding has, from the publications and research data produced to the patents filed and theses prepared thanks to it. We could then share it through our open linked-data environment.

We then help:

	Our supervisors to see the impact of our Open Science policies,
	Our European project support staff to easily find and contact researchers who might need help,
	By ricochet, our researchers and fellow citizens to produce and get access to a more open and better science.

We hope to extend this initiative to all the projects funded in the Open data environment, like the French ANR projects, providing better support, easy and transparent evaluation and progressively making Open Science easier to produce for researchers and more transparent for all.

description: Assuming the existence of a 5D purely kinetic scalar field on the class of warped product spaces we investigate the possibility of mimic both an inflationary and a quintessential scenarios on 4D hypersurfaces, by implementing a dynamical foliation on the fifth coordinate instead of a constant one. We obtain that an induced chaotic inflationary scenario with a geometrically induced scalar potential and an induced quasi-vacuum equation of state on 4D dynamical hypersurfaces is possible. While on a constant foliation the universe can be considered as matter dominated today, in a family of 4D dynamical hypersurfaces the universe can be passing for a period of accelerated expansion with a deceleration parameter nearly -1. This effect of the dynamical foliation results negligible at the inflationary epoch allowing for a chaotic scenario and becomes considerable at the present epoch allowing a quintessential scenario.

Signal for space-time noncommutativity: the Z -> gamma gamma decay in the renormalizable gauge sector of the theta-expanded NCSM

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose the Z -> gamma gamma decay, a process strictly forbidden in the standard model, as a signal suitable for the search of noncommutativity of coordinates at very short distances. We compute the Z -> gamma gamma partial widthin the framework of the recently proposed renormalizable gauge sector of the noncommutative standard model. The one-loop renormalizability is obtained for the model containing the usual six representations of matter fields of the first generation. Even more, the noncommutative part is finite or free of divergences, showing that perhaps new interaction symmetry exists in the noncommutative gauge sector of the model. Discovery of such symmetry would be of tremendous importance in further search for the violation of the Lorentz invariance at very high energies. Experimental possibilities of Z -> gamma gamma decay are analyzed and a firm bound to the scale of the noncommutativity parameter is set around 1 TeV.

description: Intrusion Detection Systems (IDS) are now an essential element when it comes to securing computers and networks. Despite the huge research efforts done in the field, handling sources' reliability remains an open issue. To address this problem, this paper proposes a novel contextual discounting method based on sources' reliability and their distinguishing ability between normal and abnormal behavior. Dempster-Shafer theory, a general framework for reasoning under uncertainty, is used to construct an evidential classifier. The NSL-KDD dataset, a significantly revised and improved version of the existing KDDCUP'99 dataset, provides the basis for assessing the performance of our new detection approach. While giving comparable results on the KDDTest+ dataset, our approach outperformed some other state-of-the-art methods on the KDDTest-21 dataset which is more challenging.

description: The physics of the state at even denominator fractional fillings of Landau levels depends on the Coulomb pseudopotentials, and produces, in different GaAs Landau levels, a composite fermion Fermi sea, a stripe phase, or, possibly, a paired composite fermion state. We consider here even denominator fractions in graphene, which has different pseudopotentials as well as a possible four fold degeneracy of each Landau level. We test various composite fermion Fermi sea wave functions (fully polarized, SU(2) singlet, SU(4) singlet) as well as the paired composite fermion states in the n=0 and $n=1$ Landau levels and predict that (i) the paired states are not favorable, (ii) CF Fermi seas occur in both Landau levels, and (iii) an SU(4) singlet composite fermion Fermi sea is stabilized in the appropriate limit. The results from detailed microscopic calculations are generally consistent with the predictions of the mean field model of composite fermions.

description: Tangibles are small, graspable objects that act as input devices or physical representations of digital data. Oftentimes, it is desirable to track the position of tangibles on a surface and their relation to each other. However, outside-in tracking techniques - such as capacitive touchscreens or cameras - require setting up elaborate infrastructure and are prone to occlusion or interference. We propose Dothraki, an inside-out tracking technique for tangibles on flat surfaces. An optical mouse sensor embedded in the tangible captures a small (36×36 pixel / 1×1 mm), unique section of a black-and-white De-Bruijn dot pattern printed on the surface. Our system efficiently searches the pattern space in order to determine the precise location of the tangible with sub-millimeter accuracy. Our proof-of-concept implementation offers a recognition rate of up to 95%, robust error detection, an update rate of 14 Hz, and a low-latency relative tracking mode.
An investigation of high speed, thin steel rotor, annular, double sided, linear induction motors
Creators: name: Peabody, Frank Gerald
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this dissertation is to analyse the performance of a linear induction motor suitable to drive a circular saw blade. A selection of analytical methods available from the field of electrical machine theory was used to investigate the particular type of motor. The theoretical analysis is supported by an extensive experimental investigation. Although LIMs have been designed, analyzed and applied in other applications, significant differences exist between those LIMs and the one used for the new application. These include: the annular shaped motor, the smaller air gap, and the rotor which is thin and made of steel. Because of these differences, the methods used by previous investigators were not sufficient to design the LIM required. The theoretical analysis used a selection of methods described in the literature to quantify the effect of the rotor material, the end effect and the edge effect. New methods are described to analyse the effect of the annular shape, the normal forces on the rotor and the coil connection. In addition, a new consideration in the optimisation of these type of motors is described. An extensive experimental program was undertaken. Six different linear motors were constructed with output powers ranging from one to fifty kWatts. In addition, inverters, dynamometers, flux measurement apparatus, speed measurement, thrust measurement and friction measurement apparatus were designed and constructed. The effects on performance of slot harmonics, winding connections, the end effect and the edge effect were measured. Several contributions to the field of electrical machine theory are presented. The first is a new annular disc motor resistivity correction factor. Second, is the analysis of the effects of poles in parallel versus in series in linear induction motors. Third, is the experimental comparison between odd and even pole designs. The fourth is a second optimum goodness consideration for LIMs, which had not previously been considered. The fifth is the analysis of the rotor/stator attractive force for magnetic rotor double sided motors and a description of the flux (crenelated flux) which causes the force. Finally, a criterion for when the re-entry effect may occur is presented.

description: In the history of the European Union, a gradual shift from national responsibilities to the European level can be observed: Due to the overall dynamics of the EU system, instruments and competences for actions have been transferred from the national capitals to 'Brussels'. In particular since 'Maastricht', this development has provoked a reinforced debate on democratic governance and public support for the European Union, raising the question whether or not the EU has a 'democratic deficit'. A democratic deficit can either be explained by the institutional arrangements and especially the limits of the European Parliament as a full fledged parliament. Or it might be described wirh the lack of a European civil society serving as a communicaror between the EU and its national societies. Following this second approach, the article analyses - after having revealed the concept of civil society - several stages of public participation in the European Integration history, covering the integration process from the late 1940s up to the Laeken declaration and the European Convention in 2002/03. It scrutinizes in particular in how far the formation of a European civil society can be observed and discusses along the lines of public support if democratic legitimacy could be ensured by civil society actors.

Confinement into a state with persistent current by thermal quenching of loop of Josephson junctions

description: We study a loop of Josephson junctions that is quenched through its critical temperature. For three or more junctions, symmetry breaking states can be achieved without thermal activation, in spite of the fact that the relaxation time is practically constant when the critical temperature is approached from above. The probability for these states decreases with quenching time, but the dependence is not allometric. For large number of junctions, cooling does not have to be fast. For this case, we evaluate the standard deviation of the induced flux. Our results are consistent with the available experimental data.

description: We study a single field inflationary model modified by a non-minimal coupling term between the Ricci scalar $R$ and the scalar field $φ$ in the context of constant-roll inflation. The first-order formalism is used to analyse the constant-roll inflation instead of the standard methods used in the literature. In principle, the formalism considers two functions of the scalar field, $W=W(φ)$ and $Z=Z(φ)$, which lead to the reduction of the equations of motion to first-order differential equations. The approach can be applied to a wide range of cosmological situations since it directly relates the function $W$ with Hubble parameter $H$. We perform the inflationary analysis for power-law and exponential couplings, separately. Then, we investigate the features of constant-roll potentials as inflationary potentials. Finally, we compare the inflationary parameters of the models with the observations of CMB anisotropies in view of realize a physically motivated model.

description: The rise of the digital humanities has posed research libraries to new challenges. Since researchers’ demands and requests are changing, libraries need to adopt their services while staff members need to update their knowledge of new methodologies to become the research librarian of the future (Ekstrøm et al, 2016). To learn more about the changing needs of researchers, the National Library of the Netherlands (KB) has set up the Researcher-in-Residence Program five years ago. The program allows early-career researchers to spend six months at the KB’s Research Department to work on their research question together with technical support from one of KB’s Research Software Engineers, collections expertise from a digital curator and project support from a digital scholarship advisor while using KB’s digital collections (Wilms, 2017). Since 5 years, 11 researchers participated in the program, 7 tools have been built and 5 datasets were created and published on the KB Lab at http://lab.kb.nl.

In this paper we will reflect on the lessons learned and benefits of the program for the KB after five years, both on the short as well as long term. Which user needs did we identify? How could research libraries adopt to these changing needs? And what more can research libraries gain from collaborating with researchers?

We will address these questions by first focusing on the short-term benefits. We will give an

overview of all the projects and the evaluation of the program done in 2017 by visiting researcher Michael Gasser. Second, we will share the long-term benefits of the program for the KB by highlighting two aspects: 1) The researcher-in-residence program creates ambassadors for the library as the researchers promote their work and therefore our collection and Lab to their community. 2) By hosting researchers at the offices of the KB, we were not only able to assist and learn from them but also got to know them and their supervisors better. This allowed us to increase our academic network, set-up several follow-up research projects and currently we are exploring the implementation of one of the projects’ outcomes in one of the KB’s services.

By showcasing a follow-up project, we follow the plea of Peter Leonard to ‘put TDM in the mainstream’ (2016). Similarly, Humphreys (2018) called for ‘Applied Digital Humanities’ just like Kleppe (2018) referred to ‘Libraries as incubators for DH Research Results’. It shows how research libraries can benefit in several ways of collaborating with Digital Humanities scholars: not only by assisting them but also by going beyond a service-oriented approach and acts as full research partner (Boekestein 2017; Ekstrøm et al, 2016).

Modeling of tunnel oxide transistors
Creators: name: Chu, Kan Man
Publisher: name: University of British Columbia
Year: 2010

description: Two improvements to a comprehensive analytic model which describes the steady-state current in a metal-insulator-semiconductor tunnel junction are reported. The first modification replaces the conventional two-band representation of the thin oxide band structure with a one-band model. In this approach the electron barrier height for tunneling is always less than the hole barrier height by an amount equal to the semiconductor band gap. The second improvement enables the energy dependence of the electron and hole tunneling probability factors to be taken into account. This is accomplished by expressing the tunneling probabilities as short-term series expressions. The capability of the model to accurately predict the electrical characteristics of metal-insulator-semiconductor (MIS) tunnel junctions is demonstrated by simulating the d.c. and a.c. performance of three major types of transistor with tunnel oxide emitters, namely the tunnel emitter transistor (TETRAN), MIS-emitter transistor (MISET) and polysilicon emitter transistor (PET). Experimental data for the d.c. characteristics of all these devices are available and are found to be well- described by the predictions of the models. No experimental data for the limits of high frequency operation of the TETRAN, MISET and pnp PET have yet been reported. The models presented here suggest what those limits can be expected to be.
Is This the Way to Reproducibility?
Creators: name: Herterich, Patricia

name: Project, The Turing Way
Publisher: name: Zenodo
Year: 2019

description: Reproducible research is necessary to ensure that scientific work can be trusted. In addition to making publications available open access, funders and publishers are beginning to require that publications include access to the underlying data and the analysis code. The goal is to ensure that all results can be independently verified and built upon in future work, make research transparent for the benefit of the wider society and regain trust in research results.

This is sometimes easier said than done. Sharing data and code requires understanding of data management, library sciences, software development, and continuous integration techniques: skills that are not widely taught or expected of academic researchers and data scientists. Likewise, research data librarians can only provide support with some aspects of a reproducible research process, typically focusing on data management and sharing. Whilst reproducibility is slowly becoming more of a focus for research data librarians in the US, examples of similar posts in Europe are lacking (Sayre & Riegelman, 2018, Steeves, 2017). One of the key responsibilities of a “reproducibility librarian” will be establishing collaborations with a variety of stakeholders, to ensure they can point academics to resources covering reproducible practices throughout the full research life cycle.

The talk will introduce “The Turing Way” project, a 5 month project led by the Alan Turing Institute to bring together research software engineers and research data librarians in order to write a handbook to support students, their supervisors, funders and journal editors in ensuring that reproducible data science is “too easy not to do”. We will present the first release of the resource created as well as the process of developing a handbook in an open and transparent collaboration between librarians, research software engineers and researchers on GitHub (https://github.com/alan-turing-institute/the-turing-way/). The talk will reflect on the collaboration and how lessons learnt can help research data librarians gain skills and networks to provide holistic open science support in the future and stake their claim in supporting reproducibility.

FINANCIAL REPORTING ANALYSIS AND INVESTMENT DECISION: EVIDENCE FROM SELECTED CORPORATE FIRMS IN NIGERIA
Creators: name: Ochie,, Chijioke Isaac
Publisher: name: TOP Journal
Year: 2024
Subjects: Financial reporting, Investment decision, Profitability and Liquidity

description: This study examined the extent financial reporting analysis affected investment decision-making on industrial goods firms in Nigeria, using firm profitability, and firm liquidity and as the independent variables while firm share capital was used as dependent variable (investment decision). Ex Post Facto research design was adopted. The study covered eleven years (2013-2023) annual accounts of the firms a sampled of ten industrial goods firms were used from a population of twelve firms. Data were analyzed with descriptive statistics and the hypotheses were tested using regression analysis via E-view 9.0.  The study revealed that firm profitability and firm liquidity have not significantly affect investment decision of industrial goods firms in Nigeria. The study therefore concluded that financial report analysis has a partial effect on investment decision; hence some portions of the reports are not significant. based on the findings, the study recommended among others that as the firm profitability shows positive and insignificant effect on investment decision this study, therefore, recommended that banks should always thrive on being profitable as this induces subscription to their shares which in turn boost their capital base.
Optical and infrared properties of V1647 Orionis during the 2003-2006 outburst. I The reflection nebula

description: Aims: The recent outburst of the young eruptive star V1647 Orionis has produced a spectacular appearance of a new reflection nebula in Orion (McNeil's nebula). We present an optical/near infrared investigation of McNeil's nebula. This analysis is aimed at determining the morphology, temporal evolution and nature of the nebula and its connection to the outburst. Method: We performed multi epoch B, V, R, I, z, and K imaging of McNeil's nebula and V1647 Ori as well as K_S imaging polarimetry. The multiband imaging allows us to reconstruct the extinction map inside the nebula. Through polarimetric observations we attempt to disentangle the emission from the nebula from that of the accretion disk around V1647 Ori. We also attempt to resolve the small spatial scale structure of the illuminating source. Results: The energy distribution and temporal evolution of McNeil's nebula mimic that of the illuminating source. The extinction map reveals a region of higher extinction in the direction of V1647 Ori. Excluding foreground extionction, the optical extinction due to McNeil's nebula in the direction of V1647 Ori is A_V ~ 6.5 mag. The polarimetric measurement shows a compact high polarization emission around V1647 Ori. The percentage of K_S band linear polarization goes from 10 -- 20 %. The vectors are all well aligned with a position angle of 90 +/- 9 degree East of North. This may correspond to the orientation of a possible accretion disk around V1647 Ori. These findings suggest that the appearance of McNeil's nebula is due to reflection of light by pre-existing material in the surroundings of V1647 Ori. We also report on the discovery of a new candidate brown dwarf or protostar in the vicinity of V1647 Ori as well as the presence of clumpy structure within HH 22A.

description: Cardiac Magnetic Resonance (CMR) is the most effective tool for the assessment and diagnosis of a heart condition, which malfunction is the world's leading cause of death. Software tools leveraging Artificial Intelligence already enhance radiologists and cardiologists in heart condition assessment but their lack of transparency is a problem. This project investigates if it is possible to discover concepts representative for different cardiac conditions from the deep network trained to segment crdiac structures: Left Ventricle (LV), Right Ventricle (RV) and Myocardium (MYO), using explainability methods that enhances classification system by providing the score-based values of qualitative concepts, along with the key performance metrics. With introduction of a need of explanations in GDPR explainability of AI systems is necessary. This study applies Discovering and Testing with Concept Activation Vectors (D-TCAV), an interpretaibilty method to extract underlying features important for cardiac disease diagnosis from MRI data. The method provides a quantitative notion of concept importance for disease classified. In previous studies, the base method is applied to the classification of cardiac disease and provides clinically meaningful explanations for the predictions of a black-box deep learning classifier. This study applies a method extending TCAV with a Discovering phase (D-TCAV) to cardiac MRI analysis. The advantage of the D-TCAV method over the base method is that it is user-independent. The contribution of this study is a novel application of the explainability method D-TCAV for cardiac MRI anlysis. D-TCAV provides a shorter pre-processing time for clinicians than the base method.
