Technical Note—Capacitated Assortment Optimization Under the Multinomial Logit Model with Nested Consideration Sets
Authors: Feldman Jacob , Topaloglu Huseyin 
Published: December 2017

We study capacitated assortment problems when customers choose under the multinomial logit model with nested consideration sets. In this choice model, there are multiple customer types, and a customer of a particular type is interested in purchasing only a particular subset of products. We use the term consideration set to refer to the subset of products that a customer of a particular type is interested in purchasing. The consideration sets of customers of different types are nested in the sense that the consideration set of one customer type is included in the consideration set of another. The choice process for customers of different types is governed by the same multinomial logit model except for the fact that customers of different types have different consideration sets. Each product, if offered to customers, occupies a certain amount of space. The sale of each product generates a certain amount of revenue. Given that customers choose from among the offered products according to the multinomial logit model with nested consideration sets, the goal of the assortment problem is to find a set of products to offer to maximize the expected revenue obtained from a customer, while making sure that the total space consumption of the offered products does not exceed a certain limit. We show that this assortment problem is NP-hard, even when there is no limit on the total space consumption of the offered products. Motivated by this complexity result, we give a fully polynomial time approximation scheme for the problem. The online appendix is available at https://doi.org/10.1287/opre.2017.1672 .
An ISOBUS-Networked Electronic Self-Leveling Controller for the Front-End Loader of an Agricultural Tractor

Published: December 2017

Abstract. There has been a growing trend toward electronic control of hydraulic systems in agricultural machinery to improve operator comfort. Rapid advances in information and communications technology and the expansion of agricultural attachments have led to the introduction of control systems following the ISOBUS standard. Feedback control of a front-end loader (FEL) using electro-hydraulic proportional valves and sensors allows automatic activation of the boom and bucket cylinders and repetitive operational sequences of FEL functions. The mechanical self-leveling systems commonly used to prevent rollback have a limited range of operation and provide overcompensation beyond that range, therefore requiring considerable driver attention when operating the FEL. This article describes the development and evaluation of an ISOBUS-networked electronic self-leveling system that uses three electronic control units (ECUs), i.e., loader, joystick, and virtual terminal ECUs, to automatically adjust the orientation of the loader bucket with respect to the ground based on real-time measurements of bucket angle and angular velocity. Key improvements to the system, compared to a previous study that developed a proportional and integral (PI)–based self-leveling controller include the addition of a velocity feedback element and a dead-time effect computation to the control loop. An embedded electronic controller was implemented on agricultural tractors to test its ability to maintain the desired bucket angle regardless of varying ground slopes or the lifting or lowering motion of the boom. In laboratory testing with a FEL simulator, the use of the velocity feedback loop enabled the bucket angles to reach reference angles of +20°, showing reductions in rise times from 0.75 to 0.51 s and from 0.84 to 0.39 s on ascending and descending slopes, respectively, compared to the PI-based self-leveling algorithm. At a traveling velocity of 2.5 km/h, there was little change in bucket angle, with an almost constant level of &lt;1°. However, at a velocity of 7.5 km/h, inflection points on the paved road caused relatively large deviations from the reference angle ranging from 3° to 5°, thus requiring the use of a look-ahead method to predict sudden changes in slope using a LIDAR sensor that can characterize the ground surface. In an outdoor bench test using a joystick to raise and lower the boom of a FEL, the self-leveling algorithm allowed the bucket angle to be maintained at the desired level, with RMSEs of 2.1±0.65° and 3.4±0.81° in the raising and lowering modes, respectively; thus, it could be implemented in an electronic self-leveling system for a FEL, which could then be employed in an ISOBUS-networked tractor offering the potential to eliminate the possibility of load rollback.

Published: December 2017

Abstract. Modern hog farrowing operations have reached a state in which the environmental conditions necessary for piglets are vastly different than those required by sows. A hog-cooling pad has been developed by Purdue University researchers to alleviate thermally-induced stress in the sow. Understanding the basic thermal properties of the device is critical to the development of the technology, and this article documents the experimentation performed on the unit to measure some of those characteristics. A preliminary experimental investigation into the thermal response of the device with no external heat loading under a variety of coolant flow and temperatures is presented. The sow-cooling panel reacts as a Newtonian convective device and provides a uniform top surface temperature. The results indicate that device is highly conductive to the top panel and reasonably well insulated from the environment. Keywords: Convection, Cooling, Farrowing, Heat capacity, Swine, Thermal response.
Telematic performance and the challenge of latency
Authors: Rofe Michael , Reuben Federico 
Published: December 2017

Abstract
Any attempt to perform music over a network requires engagement with the issue of latency. Either latency needs to be reduced to the point where it is no longer noticeable or creative alternatives to working with latency need to be developed. Given that Online Orchestra aimed to enable performance in community contexts, where significant bandwidth and specialist equipment were not available, it would not be possible to reduce latency below the 20–30ms cut-off at which it becomes noticeable. Instead, Online Orchestra developed new software that controls network latency, locking it to musical tempo. This in turn enabled musicians to perform precise rhythmic music in a latency-rich environment.
Using the phased array antenna to increase geometric size of the interrogation zone in a UHF RFID system

Published: December 2017

Abstract
An attempt to increase the geometric size of the interrogation zone in UHF RFID systems with a phased array antenna is presented in this paper. The interrogation zone should be as large as possible. However, energy can be transferred to transponders only to a limited distance. The greatest flexibility in developing RFID applications and shaping the interrogation zone can be achieved using a phased array antenna. The perceived issues have been effectively dealt with and the solution has been proposed on the basis of an elaborated model. Conducted studies have been used to develop a software tool in the Mathcad environment. The research results are analyzed in detail for different system configurations and can be implemented in practical projects to be developed in cooperation with the industry.

Die Schlussformel »bis der Esel auf die Leiter klettert« im Kolophon der mittelalterlichen hebräischen Handschriften in Aschkenas
Authors: Riegler Michael 
Published: December 2017

Abstract:This article discusses one item found in the colophons of medieval Hebrew manuscripts copied in Ashkenaz. Some opening and closing scribal formulas were found to be typical of the various cultural expanses of the Jewish world. Here we survey the Hebrew colophons for the closing formula at the end of the copying: »עד שיעלה חמור בסולם« (»until a donkey will go up the ladder«), a formula we found in 228 manuscripts, of which 130 are from Ashkenaz (including the Provence in France) making up over half (57 %) of the total manuscripts copied in this area. The rich imagination of the scribes wrought a few changes to the basic formula - not only a donkey »up the ladder« but also other animals and other objects. This formula, which first appears in a thirteenth century manuscript, is tracked in this article up until the middle of the 16th century. We discuss the origin of the formula, whether it is from Jewish or universal cultural sources. »The donkey formula« was used not only in colophons but in Hebrew literary sources as well. The question is whether the scribe used the formula in jest or to express a wish that »nothing bad should happen to him« since »never« will a donkey go up a ladder. There is no definite answer. The formula has spread from Ashkenazic culture to other areas, including Italy, Spain, Byzantium and the Middle East.
Reliable software-based control as enabler for flexible production systems
Authors: Soler Perez Olaya Santiago , Mätzler Stefan , Wollschlaeger Martin 
Published: December 2017

Abstract
The current evolution of the industrial production systems to cyber physical production systems requires an increased
flexibility of the system structure that is nowadays still difficult to find in the industrial systems. The control
applications are extremely strict by requiting jitter-free communication of sensor and control values in networked control
systems. The software-based control approach presented here enhances the reliability of the control system using a control
value matrix as information source. This approach benefits of predictive control algorithms that rely on model-based
strategies.
Microbiostratigraphy of the Berriasian–Valanginian boundary in eastern Crimea: foraminifers, ostracods, organic-walled dinoflagellate cysts

Published: December 2017

AbstractThorough study of foraminifers, ostracods and dinoflagellate remnants from the Zavodskaya Balka and Koklyuk sections helps to characterize the detailed biostratigraphic division of the Berriasian / Valanginian boundary sequence in the Feodosiya district of eastern Crimea. The foraminifer and dinocyst associations from the lower part of the sequence are clearly comparable with common Berriasian associations throughout all Mountain Crimea. On the other hand, foraminifer, ostracod and dinocyst associations from its upper part have been recorded only in eastern Crimea. The upper foraminifer level corresponds to the boreal ammonite zones from the Tauricum-Verrucosum (Upper Berriasian-Valanginian). Most of the ostracod species are endemic. The base of the uppermost dinocyst level correlates with the Lower Valanginian Paratollia zone from north-western Europe.
What’s in a Name? Equal Treatment, Union Citizens and National Rules on Names and Titles
Authors: Mohay Ágoston , Tóth Norbert 
Published: December 2017

Abstract
The construction of names and the use of nobility titles is not regulated by European Union law. Yet the Court of Justice of the EU has had to deal with such issues on various occasions where national rules on names or titles had to be contrasted with the EU law on equal treatment, Union citizenship and free movement and residence. Rules on names fall essentially within the competence of the member states, but the states have to regard EU law when exercising this competence. Our paper undertakes to analyse this issue in light of a recent relevant judgment, the Bogendorff von Wolffersdorff case, having regard also to the Court’s reasoning regarding the national constitutional identity clause [Art 4 (2)TEU]. We argue – inter alia – that the Court of Justice decided in this judgment not to favour the rights of a free-moving EU citizen (even if the judgment admittedly affects only a limited circle of individuals) and put national constitutional identity first, yet the way in which the identity clause was used by the Court is also debatable in our view.
Supervised Learning and Knowledge-Based Approaches Applied to Biomedical Word Sense Disambiguation
Authors: Antunes Rui , Matos Sérgio 
Published: December 2017

AbstractWord sense disambiguation (WSD) is an important step in biomedical text mining, which is responsible for assigning an unequivocal concept to an ambiguous term, improving the accuracy of biomedical information extraction systems. In this work we followed supervised and knowledge-based disambiguation approaches, with the best results obtained by supervised means. In the supervised method we used bag-of-words as local features, and word embeddings as global features. In the knowledge-based method we combined word embeddings, concept textual definitions extracted from the UMLS database, and concept association values calculated from the MeSH co-occurrence counts from MEDLINE articles. Also, in the knowledge-based method, we tested different word embedding averaging functions to calculate the surrounding context vectors, with the goal to give more importance to closest words of the ambiguous term. The MSH WSD dataset, the most common dataset used for evaluating biomedical concept disambiguation, was used to evaluate our methods. We obtained a top accuracy of 95.6 % by supervised means, while the best knowledge-based accuracy was 87.4 %. Our results show that word embedding models improved the disambiguation accuracy, proving to be a powerful resource in the WSD task.
Geht die Physikotheologie der Ethikotheologie vorher? Ein Blick auf Kants Prioritätsthese
Authors: Kravitz Amit 
Published: December 2017

Abstract:Two kinds of natural theology discussed by Kant have thus far been intensively investigated: physicotheology and ethicotheology. However, the question concerning their precise relation to each other has been ignored. As I argue, understanding the way in which Kant conceived of this relation is crucial for understanding his approach to natural theology as a whole. In this paper I illuminate this relation in light of Kant’s priority thesis, according to which physicotheology precedes ethicotheology, and I show that the prevalent view, according to which physicotheology and ethicotheology are two separate kinds of theologies, must be revised.

Published: December 2017

Abstract
An edge-magic total labeling of an (n,m)-graph G = (V,E) is a one to one map λ from V(G) ∪ E(G) onto the integers {1,2,…,n + m} with the property that there exists an integer constant c such that λ(x) + λ(y) + λ(xy) = c for any xy ∈ E(G). It is called super edge-magic total labeling if λ (V(G)) = {1,2,…,n}. Furthermore, if G has no super edge-magic total labeling, then the minimum number of vertices added to G to have a super edge-magic total labeling, called super edge-magic deficiency of a graph G, is denoted by μs(G) [4]. If such vertices do not exist, then deficiency of G will be + ∞. In this paper we study the super edge-magic total labeling and deficiency of forests comprising of combs, 2-sided generalized combs and bistar. The evidence provided by these facts supports the conjecture proposed by Figueroa-Centeno, Ichishima and Muntaner-Bartle [2].

Published: December 2017

Zusammenfassung
Während der Entwicklung führt das Zusammenwirken von Erfahrung und genetisch festgelegter Information zur Ausbildung und Optimierung neuronaler Schaltkreise und Verhaltensweisen. Daher üben Lebensbedingungen einen großen Einfluss auf das Gehirn aus. Bis heute häufen sich Nachweise dafür, dass die Haltung von Tieren in sogenannten „stimulierenden/angereicherten“ Käfigen erhebliche Auswirkungen auf das Gehirn auf molekularer, anatomischer und funktionaler Ebene hat, im Vergleich zu Tieren, die in „Standard“käfigen gehalten werden. In unserem Artikel geben wir einen kurzen Überblick dieses Forschungsgebietes und beschreiben die Unterschiede der Forschungsergebnisse auf dem Gebiet der Plastizität des visuellen Systems von Nagern, die in stimulierenden Käfigen gehalten werden im Vergleich zu Nagern aus Standardkäfigen. Außerdem gehen wir kurz auf Studien ein, die in vergleichbarer Weise die Auswirkungen von „angereicherten“ Lebensbedingungen bei Menschen untersuchen. Zusammenfassend ist festzustellen, dass Studienergebnisse immer im Kontext mit den Haltungsbedingungen der Versuchstiere gesehen werden müssen.
Global periodic solutions in a plankton-fish interaction model with toxication delay
Authors: Sharma Amit 
Published: December 2017

AbstractIn this paper, a plankton-fish interaction model is proposed and analyzed with the help of delay differential equations. Firstly, the elementary dynamical properties of the system in the absence of time delay is discussed. Then, we have established the existence of local Hopf-bifurcation as the time delay crosses its threshold value. The explicit results for stability and direction of the bifurcating periodic solution are derived by using normal form theory and center manifold arguments. In addition, special attention is paid to the global continuation of local Hopf bifurcations. Using the global Hopf-bifurcation result of [38] for functional differential equations, we establish the global existence of periodic solutions. The outcomes of the system are validated through numerical simulations in the concluding section.
Ordinary People on Television

Published: December 2017

AbstractBy using a longitudinal design and measuring television content and the occurrence of ordinary television and ‘ordinary’ participants at four different points in time from 1982 to 2011, this study investigates the alleged shift towards ordinariness in the 1990s. Using Sweden as a test case, three research questions are posed: To what extent did ordinary television programming increase during the 1990s? To what extent did the participation of ordinary people increase as a consequence of this shift? To what extent has public service television adapted to commercial competition through broadcasting more ordinary television? The analysis confirms the alleged shift towards ordinariness. Ordinary television and ordinary participants did increase during the studied era, but a key argument put forward is that this shift occurred gradually and that one should avoid using overdramatic epithets to characterise it. The results also suggest that the public service broadcaster (SVT) also moved towards ordinariness but that this change was modest and occurred later than expected in Sweden.
Differences in the maturation level among life histories of the Japanese eel Anguilla japonica in the Nagata River, Japan

Published: December 2017

Abstract
In order to understand the silver eel migration behavior of the Japanese eel Anguilla japonica, the life history of both the yellow stage (immature stage) and the silver stage (early maturing stage) was examined during the silver eel migration period, using otolith microchemical analysis of strontium (Sr) and calcium (Ca) concentrations. The mean Sr:Ca ratios in A. japonica from the elver mark to the otolith edge indicate eels of several general categories of migratory histories, including sea eels (average Sr:Ca ratios, ≥ 6.0 × 10-3), estuarine eels (average Sr:Ca ratios, 2.0 × 10-3 ≤ Sr:Ca < 6.0 × 10-3) and river eels (average Sr:Ca ratios, < 2.0 × 10-3), based on the criteria reported previously in A. japonica. A significant negative correlation was observed between the gonadosomatic index (GSI) and the mean Sr:Ca ratios during the growth phase after recruitment. Gonads of river eels were more developed compared to eels with other migratory histories. It thus appears that the maturation level for the silver eel migration to the open ocean varies depending on the life history.
