description: As the very first session proclaimed, the Star Athletica case has not been a model of total clarity on the Supreme Court’s part. I’m going to explore that proposition. I will go through some basic elements of the copyright statute, and will then apply those rules to several examples. The Copyright Act sets out the category of pictorial, graphic, and sculptural (“PGS”) works, whose statutory definition includes applied art. That was the subject matter at issue in Star Athletica. The statute also provides that PGS works “shall include works of artistic craftsmanship insofar as their form but not their mechanical or utilitarian aspects are concerned.” “Works of artistic craftsmanship” has been a somewhat overlooked category, but I think, as a result of Star Athletica and also the pending amendments of the Compendium of U.S. Copyright Office Practices, that this category will receive a lot more attention. It does not, however, necessarily follow that the meaning of that category will be any clearer than the standard for what is a PGS work.

description: Quantum physics is considered to be equally important and challenging for teaching physics at school. This paper aims to provide an empirical basis for the construction of guidelines for a teacher training course on quantum physics, which is particularly focused on teachers’ needs. The educational reconstruction for teacher education leads the presented investigation. The reconstruction is based on the analysis of existing concepts for quantum physics teaching in schools and the empirical collection of teachers’ views on them. The focus of this paper is on the collection and evaluation of teachers’ views. For this purpose, an iterative communication technique was used to collect and quantify expert opinions, the Delphi method, which is established in didactic research. As a result of the educational reconstruction, six guidelines are presented which support the lecturer in planning and conducting the teacher training. The guidelines imply an advanced training program that follows the path from classical to quantum physics with special emphasis on key experiments.
description: Das Themengebiet Quantenphysik gilt als gleichermaßen bedeutend wie herausfordernd für den Physikunterricht in der Schule. Die Erzeugung einer empirischen Basis für die Konstruktion von Leitlinien für eine im besonderen Maße adressatenspezifische Lehrerfortbildung zum Thema Quantenphysik ist Gegenstand dieses Beitrags. Die Didaktische Rekonstruktion zur Erarbeitung von Leitlinien für Lehrerfortbildungen leitet die vorgestellte Untersuchung. Basis der Rekonstruktion bilden die Analyse von bestehenden Konzepten zum Quantenphysikunterricht in der Schule und die empirische Erhebung von Sichtweisen der Lehrenden auf diese. Der Fokus liegt in diesem Beitrag auf der Erhebung und Auswertung der Sichtweisen von Lehrenden. Zu diesem Zweck wurde eine iterative Kommunikationstechnik zur Erhebung und Quantifizierung von Expertenmeinungen verwendet, die Delphi-Methode, welche in der fachdidaktischen Forschung etabliert ist. Als Ergebnis der Didaktischen Rekonstruktion werden sechs Leitlinien vorgestellt, die Dozenten bei der Planung und Durchführung der Fortbildung unterstützen. Die Leitlinien implizieren eine Fortbildung, die den Weg von der klassischen zur Quantenphysik beschreitet und dabei Schlüsselexperimente in das Zentrum stellt.

description: Σκοπός της διπλωματικής εργασίας με τίτλο «Παραγωγή βελτιωμένων βιοεξανθρακωμάτων για περιβαλλοντικές χρήσεις» ήταν η διερεύνηση της προσροφητικής ικανότητας ρύπων από ενεργοποιημένα και μη εξανθρακώματα αγροτικών αποβλήτων, όπως πυρήνων ροδάκινου, κελυφών αμυγδάλου, κελυφών καρυδιού, κομπόστας και κληματίδων. Τα εξανθρακώματα παρασκευάστηκαν από πυρόλυση των προαναφερθέντων πρώτων υλών σε θερμοκρασίες 700-800oC. Εν συνεχεία, ακολούθησε η φυσική ενεργοποίηση των παραγόμενων εξανθρακωμάτων στις αντίστοιχες θερμοκρασίες, με ατμό ή διοξείδιο του άνθρακα. Τα προϊόντα αναλύθηκαν ως προς τη σύσταση και την απόδοσή τους σε εξανθράκωμα, βιοέλαιο και βιοαέριο. Παράλληλα μετρήθηκε η ειδική επιφάνεια, ο όγκος και το μέγεθος των πόρων τους.

Ακολούθησε συγκριτική αξιολόγηση των αποτελεσμάτων κυρίως για τις συνθήκες στις οποίες επετεύχθησαν οι υψηλότερες τιμές ειδικής επιφάνειας, πορώδους και απόδοσης βιοεξανθρακώματος. Συνολικά, παρατηρήθηκε ότι υψηλότερες τιμές ειδικής επιφάνειας και μέσου μεγέθους πόρων εμφανίστηκαν σε υψηλότερες τιμές θερμοκρασίας παρουσία ατμού. Αντίθετα, τα ενεργοποιημένα εξανθρακώματα παρουσία διοξειδίου του άνθρακα εμφάνισαν μεγαλύτερη περιεκτικότητα σε οργανική ύλη και μικρότερη ειδική επιφάνεια. Τα εξανθρακώματα τα οποία πρέπει να διερευνηθούν περαιτέρω ως προσροφητικά υλικά ρύπων είναι εκείνα που προέκυψαν μετά από ενεργοποίηση με ατμό, για τα δείγματα πυρήνων ροδάκινου των 600oC, κελυφών αμυγδάλου και κελυφών καρυδιού των 700oC, κομπόστας των 800oC, καθώς επίσης και όλα τα ενεργοποιημένα εξανθρακώματα παρουσία CO2 στους 800oC.

description: Η εργασία έχει ως σκοπό τον προσδιορισμό της φέρουσας ικανότητας εδάφους που χρησιμοποιείται για την κατασκευή επιχώματος οδοποιίας στην περιοχή Γουβών Ηρακλείου.
Τα αποτελέσματα του Καλιφορνιακού Λόγου Φέρουσας Ικανότητας (CBR) συμβάλουν στον καθορισμό του πάχους των στρώσεων και θεωρούνται απαραίτητα για την διασφάλιση της σωστής κατασκευής και της ευστάθειας ενός οδοστρώματος.
Πραγματοποιήθηκε δειγματοληψία από τρεις θέσεις του έργου με σκοπό την εκτίμηση των γεωτεχνικών παραμέτρων και του CBR του γεωϋλικού σε καθορισμένες συνθήκες υγρασίας και πυκνότητας.
Αρχικά, τα δείγματα αναλύθηκαν κοκκομετρικά, προσδιορίσθηκαν οι τιμές των ορίων Atterberg, ταυτοποιήθηκαν και ταξινομήθηκαν κατά USCS και AASHTO και εκτιμήθηκε η βέλτιστη υγρασίας συμπύκνωσης. Ακολούθησαν οι δοκιμές προσδιορισμού του Καλιφορνιακού Λόγου Φέρουσας Ικανότητας (CBR) σε καθορισμένες συνθήκες υγρασίας και πυκνότητας του γεωϋλικού.
Τα αποτελέσματα αξιολογήθηκαν με βάση τις Προσωρινές Εθνικές Τεχνικές Προδιαγραφές ΠΕΤΕΠ 02-07-01-00 και τα γεωϋλικά χαρακτηρίσθηκαν ως προς την καταλληλότητά τους για την κατασκευή επιχωμάτων οδοποιίας.
description: The aim of the thesis is to determine the suitability of a geomaterial for construction of highway embankment in Gouves (Iraklion, Crete).
The results of California Bearing Ratio (CBR) tests are used for the evaluation of subgrade strength and determination of pavement thickness and its component layers.
Samples was taken from three project sites and laboratory tests were carried out on every sample for the determination of geotechnical parameters and CBR values (under specified moisture content and density).
Initially, the particle size distribution analysis and the Atterberg limits values of the samples were determined. Following, the geomaterials were classified according USCS and AASHTO standards and the optimum moisture content was evaluated. Next California Bearing Ratio (CBR) tests were performed at specified moisture and density conditions.
The results were evaluated according to Temporary National Technical Specifications (TNTS 02-07-01-00) and the geo-materials were characterized for their suitability for an embankment construction.

Η διπλωματική εργασία χωρίζεται σε τρία μέρη. Στο πρώτο μέρος γίνεται αναφορά στη γεωλογία και στη γεωτεκτονική εξέλιξη της περιοχής μελέτης . Το δεύτερο μέρος αναφέρεται στο θεωρητικό υπόβαθρο των υπαίθριων εκμεταλλεύσεων, στις διαφορετικές μεθόδους που υπάρχουν, αλλά και στην τεχνική ορολογία που συνδέεται με αυτές. Επίσης γίνεται λόγος για τις υπαίθριες εκμεταλλεύσεις μαρμάρου, καθώς και τα στάδια που πραγματοποιούνται για την εξόρυξη, τη φόρτωση και τη μεταφορά του. Στο τρίτο τμήμα της παρούσας διπλωματικής εργασίας αναλύεται λεπτομερώς η σχεδιαστική διαδικασία δημιουργίας του κοιτασματολογικού μοντέλου από προ υπάρχουσες τομές. Εν συνεχεία, παρουσιάζεται η πραγματοποίηση εκ νέου σχεδιασμού για την επέκταση της εκμετάλλευσης.

description: Στην παρούσα εργασία μελετάται ο σχεδιασμός υπόγειας εκμετάλλευσης μαρμάρου με τη μέθοδο θαλάμων και στύλων με βάση τα αποτελέσματα γεωτρήσεων πυρηνοληψίας και τα μηχανικά χαρακτηριστικά του μαρμάρου με στόχο την εξασφάλιση της ασφάλειας και της μέγιστης απολήψεως του κοιτάσματος. Για τον σχεδιασμό της εξόρυξης γίνεται χρήση σχεδιαστικών και λογισμικών προγραμμάτων όπως το AutoCAD™ και το FLAC3D™. Με τη βοήθεια των παραπάνω, γίνεται η προσομοίωση της συμπεριφοράς του πετρώματος κατά τα διάφορα στάδια της εξόρυξης , τα οποία έχουν οριστεί αρχικά.
Τα δεδομένα των πυρηνοληπτικών γεωτρήσεων στην περιοχή, χρησιμοποιήθηκαν ώστε να γίνει η επιλογή των ορίων της υπόγειας εκμετάλλευσης που θα αποδώσει τη μέγιστη απόληψη δολομιτικού μαρμάρου. Αυτό που καθόρισε την προχώρηση της εξόρυξης, ήταν η παρουσία ασβεστιτικού μαρμάρου στο λατομείο και το οποίο θεωρείται στείρο υλικό για τη συγκεκριμένη εκμετάλλευση. Έτσι, σχεδιάστηκε η επαφή ασβεστιτικού και δολομιτικού μαρμάρου, σύμφωνα με την οποία διαχωρίστηκε το κοίτασμα από το άγονο υλικό. Στη συνέχεια, διαμορφώθηκαν τα στάδια της εκμετάλλευσης, επιλέχθηκε η μέθοδος εξόρυξης του δολομιτικού μαρμάρου και καθορίστηκαν οι διαστάσεις των ογκομαρμάρων που θα εξορυχθούν καθώς και των στύλων υποστήριξης που εγκαταλείπονται στο κοίτασμα. Σε επόμενο στάδιο, κατασκευάστηκε μοντέλο στο οποίο δόθηκαν συγκεκριμένες μηχανικές ιδιότητες (μέτρο ελαστικότητας, λόγος Poisson, συνοχή, γωνία εσωτερικής τριβής, κλπ.) του πετρώματος. Σύμφωνα με τη θέση και τη γεωμετρία της επαφής  που δημιουργήθηκε νωρίτερα, το μοντέλο χαρακτηρίστηκε σε περιοχές ασβεστιτικού και δολομιτικού μαρμάρου, έχοντας την αντίστοιχη πυκνότητα και τις αντίστοιχες μηχανικές ιδιότητες. Τέλος, η προσομοίωση της εξόρυξης πραγματοποιήθηκε αφότου τέθηκαν στο μοντέλο οι συνοριακές συνθήκες και η επιλογή του κριτηρίου Mohr – Coulomb ως κρίτηριο αστοχίας.
Κατόπιν, μελετήθηκε η συμπεριφορά του πετρώματος με το πέρας της εξόρυξης και ειδικότερα η κατακόρυφη μετατόπιση που παρατηρήθηκε σε δεδομένα σημεία των τεσσάρων στύλων υποστήριξης. Συμπερασματικά, το μοντέλο της προσομοίωσης κατέδειξε ότι το σύστημα των υπογείων παραμένει ευσταθές μέχρι το πέρας της εκμετάλλευσης.

description: By a transfer operator approach to Maass cusp forms and the Selberg zeta function for cofinite Hecke triangle groups, M. Möller and the author found a factorization of the Selberg zeta function into a product of Fredholm determinants of transfer-operator-like families: $Z(s) = \det(1-\mc L_s^+)\det(1-\mc L_s^-)$. In this article we show that the operator families $\mc L_s^\pm$ arise as families of transfer operators for the triangle groups underlying the Hecke triangle groups, and that for $s\in\C$, $\Rea s=\tfrac12$, the operator $\mc L_s^+$ (resp. $\mc L_s^-$) has a 1-eigenfunction if and only if there exists an even (resp. odd) Maass cusp form with eigenvalue $s(1-s)$. For nonarithmetic Hecke triangle groups, this result provides a new formulation of the Phillips-Sarnak conjecture on nonexistence of even Maass cusp forms.

description: Individuals who have, or are at risk for, various genetic disorders face many challenges concerning disclosures of genetic information in dating situations. We conducted a qualitative interview study of 64 individuals confronting Huntington's disease, breast cancer, or Alpha‐1 antitrypsin deficiency, examining what issues these individuals encountered, and how they viewed and addressed these—including issues of understandings, privacy, and disclosures of genetic information to various groups (e.g., family members). Incidental to the primary research questions addressed, participants also often described a series of dilemmas in dating situations that they and/or family members, friends, and fellow patients faced of whether to date, and if so, whether, what, how, why, and when to disclose their genetic risk or illness. At times, these individuals feared and experienced rejection, and hence delayed, avoided, or opposed disclosure, or disclosed indirectly or inadvertently. These data are reported in this paper and highlight the importance of patients, their loved ones, genetic counselors, and other health care providers being aware of these issues, and appreciating the complex factors involved, which can affect patients’ coping and social support. This paper, the first to explore several key aspects of disclosures of genetic information in dating, thus suggests needs for public and professional education, and future research in this area.

description: We study necessary and sufficient conditions to attain solutions of set-optimization problems in therms of variational inequalities of Stampacchia and Minty type. The notion of a solution we deal with has been introduced Heyde and Loehne, for convex set-valued objective functions. To define the set-valued variational inequality, we introduce a set-valued directional derivative and we relate it to the Dini derivatives of a family of linearly scalarized problems. The optimality conditions are given by Stampacchia and Minty type Variational inequalities, defined both by the set valued directional derivative and by the Dini derivatives of the scalarizations. The main results allow to obtain known variational characterizations for vector valued optimization problems.
Steady state Ab-initio Theory of Lasers with Injected Signals

Publisher: name: arXiv
Year: 2013
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We present an ab-initio treatment of the steady-state of lasers with injected signals that describes a regime, valid for micro lasers, in which the locking transition is dominated by cross-saturation and spatial hole-burning. The theory goes beyond standard approaches and treats multimode lasing with injected signals and finds the possibility of partially locked states and as well as repulsion of the free-running frequencies from the injected signal. The theory agrees well with exact integration of the full wave and matter equations for the system. It can also describe accurately complex modern lasers structures and is applied to the example of deformed disk lasers. We show that in the case of a one dimensional cavity in the locked or regenerative amplifier regime the theory reduces to an improved version of the Adler equations in the appropriate limit.

description: Scènes à faire: what is it, and why do we need a French name for it? Because when we explain it in English it doesn’t make any sense at all. Scènes à faire, Black’s Law Dictionary says, means “standard or general themes that are common to a wide variety of works and therefore are not copyrightable.” A number of other definitions of the term similarly deny copyrightability. For example, this is from a First Circuit case: the court “denie[d] copyright protection to elements of a work that are for all practical purposes indispensable, or at least customary, in the treatment of a given subject matter.” So again, we deny copyright protection. As Dale Cendali spoke to moments ago, most courts don’t look at it that way. The majority view is that it does not invalidate the copyright; it’s not a question of copyrightability. It’s a question of what is infringing activity and whether sharing this element actually rises to the level of infringement or not, not whether the scène à faire is copyrightable.
Sampling exactly from the normal distribution

description: An algorithm for sampling exactly from the normal distribution is given. The algorithm reads some number of uniformly distributed random digits in a given base and generates an initial portion of the representation of a normal deviate in the same base. Thereafter, uniform random digits are copied directly into the representation of the normal deviate. Thus, in contrast to existing methods, it is possible to generate normal deviates exactly rounded to any precision with a mean cost that scales linearly in the precision. The method performs no extended precision arithmetic, calls no transcendental functions, and, indeed, uses no floating point arithmetic whatsoever; it uses only simple integer operations. It can easily be adapted to sample exactly from the discrete normal distribution whose parameters are rational numbers.

description: Seit 2015 wurden in bisher drei Beobachtungsläufen periodische Raumzeitkrümmungen von großen Laserinterferometern gemessen. Das Ergebnis: Fünfzig Gravitationswellensignale konnten in den Daten gefunden werden, die jeweils vom Umkreisen und Verschmelzen von kompakten Doppelsystemen ausgelöst wurden. Zwei dieser beobachteten Systeme bestanden dabei aus Neutronensternen, die anderen Signale entstammen der Verschmelzung von Schwarzen Löchern. Durch diese Messungen wird ein bisher kaum zugänglicher Bereich des Universums nach und nach sichtbar. Es zeichnet sich ab, dass auch in Zukunft die Signale vieler verschmelzender Schwarzer Löcher, die jeweils 10 bis 40 Sonnenmassen schwer sind, den Großteil der Beobachtungen ausmachen werden. Allerdings hat der erst kürzlich analysierte Beobachtungslauf auch einige überraschende Messungen beinhaltet. Doppelsysteme, in denen die Masse nicht symmetrisch auf beide Partner verteilt ist, wurden erstmals beobachtet und ihr „Klang“ inklusive Obertöne analysiert. In zumindest einem Fall (GW190814) kann das kleine Objekt im System nicht zweifelsfrei identifiziert werden. Bei GW190521 sind die Schwarzen Löcher dagegen so massereich, dass deren Entstehung Rätsel aufgibt. Weitere Beobachtungsläufe, ebenso wie neuartige Gravitationswelleninstrumente, sind für die Zukunft geplant und werden weitere Einsichten zur Zusammensetzung, Entwicklung und Entstehung des Universums liefern.

description: Scènes à faire: What is it? Generally speaking, it’s when certain things are so commonplace, and so naturally associated with the treatment of the subject, that everyone needs to be able to use them in order to also write, or talk, or deal with that subject. What have courts found to be scènes à faire? Lots of different things, in lots of different contexts. Some are easy to picture: If you’re going to have an underwater world, having sand dollars as money, oyster shells as plates, and things like that—that makes some sense. Aquaman rides a seahorse; other underwater people might ride seahorses. Or the idea that superheroes wear capes and masks— you can understand that that’s something common to the genre that everyone should be free to use. Similarly, if you are setting something in World War II, you might have a German beer hall. If you are setting something in a small town in the American South, you might have a country music bar with a gritty atmosphere and music playing from a jukebox; it’s going to be playing a sad song, and then dancing will ensue. More things may happen after that, but the setting could have common elements.

description: We give a sharp lower bound for the selfintersection of a nef line bundle $L$ on an irregular variety $X$ in terms of its continuous global sections and the Albanese dimension of $X$, which we call the Generalized Clifford-Severi inequality. We also extend the result to nef vector bundles and give a slope inequality for fibred irregular varieties. As a byproduct we obtain a lower bound for the volume of irregular varieties; when $X$ is of maximal Albanese dimension the bound is $Vol(X) \geq 2 n! χω_X$ and it is sharp.

Super quantum probabilities and three-slit experiments -- Wright's pentagon state and the Popescu-Rohrlich box require third-order interference
Creators: name: Niestegge, Gerd
Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum probabilities differ from classical ones in many ways, e.g., by violating the well-known Bell and CHSH inequalities or another simple inequality due to R. Wright. The latter one has recently regained attention because of its equivalence to a novel noncontextual inequality by Klyachko et al. On the other hand, quantum probabilities still obey many limitations which need not hold any more in more general probabilistic theories (super quantum probabilities). Wright, Popescu and Rohrlich identified states which are included in such theories, but impossible in quantum mechanics, and they showed this using its Hilbert space formalism. Recently, Fritz et al. and Cabello detected that the impossibility of these states can be derived from very general principles (local orthogonality and global exclusive disjunction, respectively) without using Hilbert space techniques. In the paper, an alternative derivation from rather different phyisical principles will be presented. These are a reasonable calculus of conditional probability (i.e., a model for the quantum measurement process) and the absence of third-order interference. The concept of third-order interference was introduced by Sorkin who also recognized its impossibility in quantum mechanics.

description: IRBs have been criticized for long and complicated consent forms, but how IRBs make decisions about these issues hasn't been examined. I contacted leaders of 60 IRBs, and interviewed Irb leaders from 34 (response rate = 55%), and 13 members and administrators. IRBs confront challenges and dilemmas regarding these documents: What and how much these forms should include (e.g., how “perfect” forms should be). While IRBs generally seek to decrease the length and complexity, institutions and industry funders often want these forms to be legal documents. IRBs may also “nitpick” these documents without realizing the costs. This study, the first to explore how IRBs view and make decisions about consent forms, suggests underlying tensions, ambiguities, and subjectivities that have important implications for future policy, practice, education, and research.
Out-of-equilibrium properties and non-linear effects for interacting quantum impurity systems in their strong coupling regime

description: We provide an exact description of out-of-equilibrium fixed points in quantum impurity systems, that is able to treat time-dependent forcing. Building on this, we then show that analytical out-of-equilibrium results, that exactly treat interactions, can be obtained in interacting quantum impurity systems in their strong coupling regime, provided they are integrable \emph{at} equilibrium and they are "super Fermi liquids", i.e. they only allow for integer charge hopping. For such systems we build an out-of-equilibrium strong coupling expansion, akin to a Sommerfeld expansion in interacting systems. We apply our approach to the Interacting Resonant Level model, and obtain the exact expansion around the low energy fixed point of the universal scaling function for the charge current as a function of voltage, temperature, and frequency, up to order seven.

description: I’m a big student of the nineteenth century. I love the 1800s, I write about them, and I think about them a lot. There are a lot of questions in modern copyright law where we look back, and we spend time thinking about what was going on in the 1800s and opinions from the 1800s. And so when we came up with this idea to talk about the scope of copyright, I went back to the cases from the 1800s, and the Supreme Court has told us a lot about what is copyrightable and what is not from a perspective of merger—from a perspective of protecting laws or not.

description: What is merger? Let’s first take a look at what the Second Circuit says merger is. The Second Circuit says merger happens “in those instances where there is only one or so few ways of expressing an idea that protection of the expression would effectively accord protection to the idea itself.”1 A situation where, if you’ve got a monopoly on a particular way of expressing something, you’ve effectively got a monopoly on that thing—and we don’t want you to have a monopoly on that thing. I’ll talk in a little bit about what the kinds of things are. Why only one “or so few” ways? To avoid a situation where there are three ways of expressing it, and three people express it in all of those three ways, and all get exclusive rights in their particular way. Now there is still no available way for the public to express that thing that we want the public to be able to express without the interference of copyright.

title: Process parameter definition for continuous dyeing and thermofixation based on Dianix disperse dyes on Polyester fabric with aNIR technology
Creators: name: Antwi, Andy Buobu

description: Polyester fabrics are commonly dyed with the continuous disperse dyeing process and require a convection hot air dryer for drying and fixation of these fabrics. This convection hot air dryer is not only time-consuming compared to NIR drying but also energy intensive. For this reason, research was conducted to investigate if the newly developed advancedNIR® technology from Adphos Innovative Technologies GmbH is suitable for continuous disperse dyeing of polyester. There are specific parameters and temperatures which have been identified to help this technology be evaluated for its sustainable innovation potential for the textile industry. Eight disperse dyes were used from DyStar Colours Distribution GmbH, namely Dianix® XF2 (high energy) and Dianix® CC (medium energy). Trichromic colours (Dianix® Brown XF2/CC) have also been dyed to investigate the migration effect which was observed during the research. Different technology combinations were investigated for their potential application, especially spray application using rotating discs from Weitmann & Konrad GmbH & Co. KG / RotaSpray GmbH. These combined technologies could be a potential sustainable alternative process, which can be used in place of the convection hot air process, by replacing natural gas with electric power. Analysis of the final samples with optimized parameters shows improved levelness and fastness. Additional research is necessary to analyze the separate process steps in more detail.

description: Scattering hinders the passage of light through random media and consequently limits the usefulness of optical techniques for sensing and imaging. Thus, methods for increasing the transmission of light through such random media are of interest. Against this backdrop, recent theoretical and experimental advances have suggested the existence of a few highly transmitting eigen-wavefronts with transmission coefficients close to one in strongly backscattering random media. Here, we numerically analyze this phenomenon in 2-D with fully spectrally accurate simulators and provide rigorous numerical evidence confirming the existence of these highly transmitting eigen-wavefronts in random media with periodic boundary conditions that is composed of hundreds of thousands of non-absorbing scatterers. Motivated by bio-imaging applications where it is not possible to measure the transmitted fields, we develop physically realizable algorithms for increasing the transmission through such random media using backscatter analysis. We show via numerical simulations that the algorithms converge rapidly, yielding a near-optimum wavefront in just a few iterations. We also develop an algorithm that combines the knowledge of these highly transmitting eigen-wavefronts obtained from backscatter analysis, with intensity measurements at a point to produce a near-optimal focus with significantly fewer measurements than a method that does not utilize this information.

How Much Should Being Accommodate Becoming? Copyright in Dynamic and Permeable Art

description: Much of the art in genres ranging from participatory art and performance art to environmental art and found art is dynamic, or permeable, or both. That is to say, the art may be unstable or ephemeral, and may invite unpredictable change though the influence of natural or human forces, and it also may have weak, unclear boundaries that blur text and context. Dynamic and permeable art seek to present the world as a continuum in space and time – as becoming –challenging our commitments to boundaries and objects. By contrast, copyright law is firmly committed to being. Its central subject, the work of authorship, must be stable and discrete. Works of authorship can neither change over time, nor have unknown boundaries. One might think that as a consequence, dynamic and permeable art can never be subject to copyright protection. Yet copyright has developed a powerful set of tools to frame various kinds of becoming as being—that is, as stable, bounded objects that can qualify as works of authorship. This essay addresses three of those tools: (1) considering ranges and correlations as copyrightable elements of works; (2) using non-notational, trans-category fixation in audio and video; and (3) considering site-specific and found art as involving compilation. It will consider how each of the tools accommodates dynamic and permeable art, and will then consider the copyright policies that should be taken into account when setting limits for each tool’s use. All three tools raise questions of whether the works they delineate are of sufficient complexity to be more than “ideas,” and whether those works fall into a copyrightable category of work of authorship. Some of the tools also raise distinct issues. For example, when works are composed of ranges and correlations, those ranges and correlations should be conspicuous enough to provide adequate notice, and foreseeable enough that they can be said to have been authored by the artist claiming to have created them. The essay also considers the extent to which the being of copyright does not do full justice to the becoming of dynamic and permeable art, because a work of authorship sufficiently stable and discrete to be the subject of copyright will not include the full, ongoing experience of an open creation and its serendipitous transformations.
How Good Does the Science Have to Be in Proposals Submitted to IRBs?: An Interview Study of IRB personnel

description: Background: Institutional Review Boards (IRBs) have been increasingly criticized for how they review protocols, but how IRBs perceive, and make decisions about, the quality of the science of protocols has not been examined. Purpose: To explore how and when IRBs view and make decisions about the quality of the science of studies they review. Methods: I contacted the leadership of 60 IRBs (every fourth one in the list of the top 240 institutions by National Institutes of Health (NIH) funding) and interviewed IRB chairs, co-chairs, administrators, and a director from 34 IRBs (response rate = 55%), and an additional 7 members. Results: Interviewees faced several ambiguities and questions concerning the quality of the science of protocols. IRBs are often not sure how and to what extent to evaluate the science of protocols, whether the science should be ‘good enough’ (and if so, what that means) versus as good as possible. Federal regulations state that IRBs should ensure that risks are minimized, and commensurate with benefits. Thus, at times IRBs feel that changing the science is ethically necessary. But IRBs also then struggle with whether to adopt a higher threshold (1) that social and thus scientific benefits be maximized and (2) that scientific efforts and resources should not be wasted. Committees face dilemmas – for example, if a ‘perfect’ study is not feasible. For protocols already approved elsewhere (e.g., by the NIH), IRBs vary in how much they feel they can request alterations, and sometimes make changes nonetheless. Larger institutional contexts and biases can shape these issues, and IRBs differ in how much they are ‘pro-research’, and have sufficient expertise. IRBs at times also approve studies despite reservations about the science. Limitations: This study includes interviews with IRBs, but not observations of IRB meetings. Conclusions: IRBs often face ambiguities and conflicting goals in assessing scientific quality. Many IRBs try to improve the science beyond what the regulations mandate. These data have important implications for improving practice, education, research, and policy.

Restriction on types of coherent states due to gauge symmetry

description: From the viewpoint of the SU(2) coherent states (CS) and their path integrals (PI) labeled by a full set of Euler angles $(ϕ, θ, ψ)$ which we developed in the previous paper, we study the relations between gauge symmetries of Lagrangians and allowed quantum states; we investigate permissible types of fiducial vectors (FV) in the full quantum dynamics in terms of SU(2) coherent states for typical Lagrangians. We propose a general framework for a Lagrangian having a certain gauge symmetry with respect to one of the Euler angles $ψ$. We find that for the case fiducial vectors are so restricted that they belong to the eigenstates of ${\hat S}_3$ or to the orbits of them under the action of the SU(2); and the strength of a fictitious monopole, which appears in the Lagrangian, is a multiple of $\frac12$. In this case Dirac strings are permitted. Our formulations and results deepen those of the preceding work by Stone that has piloted us; we illustrate the relation between the two methods. The reasoning here does not work for a Lagrangian without the gauge symmetry. This suggests a new possibility about monopole charge quantization. Besides analogies to field theory and entanglements in quantum information (QI) are briefly mentioned.

description: Reduced speech function is a primary disability in children with cerebral palsy (CP) who have the motor speech disorder of dysarthria. Interventions for pediatric dysarthria with evidence of efficacy are greatly needed. The present exploratory study examined the effects of two intervention methods on three children with CP: (1) Lee Silverman Voice Treatment (LSVT LOUD), an intensive single-focus intervention protocol that increases sound pressure level (SPL), intelligibility, and vowel space in adults with dysarthria due to Parkinson Disease (PD) and has recent evidence suggesting effectiveness for children with CP, and (2) “Traditional” intervention, representing “treatment as usual,” consisting of instruction on breath control, positioning, articulation, and other behaviors. Examination of caregiver questionnaires, articulation assessment, and blinded listener ratings revealed greater speech function and articulatory precision, as well as utterances more often preferred and perceived as “easier to understand” after intervention. LSVT LOUD resulted in increases in speech function and SPL. Traditional resulted in increased speech function without increasing SPL. Thus, both interventions show promise for yielding increased speech function in children with dysarthria, although success may vary across linguistic levels and children.

How Conceptual Art Challenges Copyright’s Notions of Authorial Control and Creativity

description: Here’s the basic argument: that to the extent that someone exerts too little control or that there is too much unpredictability about the way in which the work will be produced, then that person is at risk of being declared not an author of the work. Copyright law looks for control and predictability, and if there’s not enough of either, then copyright law and the Copyright Office may conclude that the creator is not an “author” of the work. On the other hand, to the extent that there is too much control or too much predictability, then authors run the risk of being told that their work is not creative. In fact, the strategy for an author is to balance these sorts of competing requirements: to exert control over the ultimate product, but not so much control that you risk losing the opportunity for creative expression.
