Authors: Schwalbe Ulrich , Zimmer Daniel
Published: July 2021

Auf europäischer wie nationaler Ebene sind Buchveröffentlichungen nach wie vor rar, die den Fragen der Anwendung ökonomischer Theorie im Kartellrecht in systematischer und wissenschaftlicher Hinsicht gerecht werden. In diese Lücke stößt das Buch „Kartellrecht und Ökonomie“.

Die Neuauflage behandelt neben horizontalen Fusionen, d.h. solchen zwischen Wettbewerbern, schwerpunktmäßig auch vertikale undkonglomerate Zusammenschlüsse. Inhaltliche Erweiterungen ergeben sich aus der Fortentwicklung der Wettbewerbsökonomie. Die neuesten ökonomischen Diskussionen (z.B. zur digitalen Ökonomie, zu zweiseitigen Märkten, Ausschreibungs- und Bietermärkten, Minderheitsbeteiligungen und zu Nachfragemacht) wurden aufgenommen.

Für die Neuauflage haben die Autoren die Entscheidungspraxis der Europäischen Kommission und des Bundeskartellamtes, des EuG, EuGH, OLG Düsseldorf (als Beschwerdeinstanz nach Entscheidungen des Bundeskartellamtes) und des Bundesgerichtshofs umfassend ausgewertet.
Diagnosis of Fungal Plant Pathogens Using Conventional and Molecular Approaches
Authors: C. Dayarathne Monika , U. Mridha Amin , Wang Yong
Published: July 2021

Fungi are a large group of eukaryotes found as saprophytes, pathogens or endophytes, which distribute in every corner of our planet. As the main pathogens, fungi can cause 70–80% of total plant diseases, leading to huge crop yield reduction and economic loss. For identification of fungal plant pathogens, mycologists and plant pathologists have mainly gone through two stages, viz. morphological observation and morphology/phylogeny, and the next era might be utilizing DNA barcodes as the tool for rapid identification. This chapter accounts i) the brief history of development for fungal identification tools and main concepts, ii) the importance and confusion of “One fungus, one name” for pathogen identification, iii) more or fewer species that we need in agricultural practice, and iv) the foreground of fungal plant pathogen identification. These will help to solve the practical problems of identification of fungal pathogens in agricultural production.
Head Impact Injury Mitigation to Vehicle Occupants: An Investigation of Interior Padding and Head Form Modeling Options against Vehicle Crash
Authors: G. Koricho Ermias , Dimsdale Elizabeth
Published: July 2021

Traumatic Brain Injuries (TBI) occur approximately 1.7 million times each year in the U.S., with motor vehicle crashes as the second leading cause of TBI-related hospitalizations, and the first leading cause of TBI-related deaths among specific age groups. Several studies have been conducted to better understand the impact on the brain in vehicle crash scenarios. However, the complexity of the head is challenging to replicate numerically the head response during vehicle crash and the resulting traumatic Brain Injury. Hence, this study aims to investigate the effect of vehicle structural padding and head form modeling representation on the head response and the resulting causation and Traumatic Brain Injury (TBI). In this study, a simplified and complex head forms with various geometries and materials including the skull, cerebrospinal fluid (CSF), neck, and muscle were considered to better understand and predict the behavior of each part and their effect on the response of the brain during an impact scenario. The effect of padding thickness was also considered to further analyze the interaction of vehicle structure and the head response. The numeral results revealed that the responses of the head skull and the brain under impact load were highly influenced by the padding thickness, head skull material modeling and assumptions, and neck compliance. Generally, the current work could be considered an alternative insight to understand the correlation between vehicle structural padding, head forms, and materials modeling techniques, and TBI resulted from a vehicle crash.
Build 3D Abstractions with Wireframes
Authors: Santos Mateos Roi , M. Pardo Xose , R. Fdez-Vidal Xose
Published: July 2021

This chapter serves as an introduction to 3D representations of scenes or Structure From Motion (SfM) from straight line segments. Lines are frequently found in captures of man-made environments, and in nature are mixed with more organic shapes. The inclusion of straight lines in 3D representations provide structural information about the captured shapes and their limits, such as the intersection of planar structures. Line based SfM methods are not frequent in the literature due to the difficulty of detecting them reliably, their morphological changes under changes of perspective and the challenges inherent to finding correspondences of segments in images between the different views. Additionally, compared to points, lines add the dimensionalities carried by the line directions and lengths, which prevents the epipolar constraint to be valid along a straight line segment between two different views. This chapter introduces the geometrical relations which have to be exploited for SfM sketch or abstraction based on line segments, the optimization methods for its optimization, and how to compare the experimental results with Ground-Truth measurements.

Authors: G. Sahin Ozlem
Published: July 2021

The novel coronavirus also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) whose origin is still having uncertainties related to the existence of an intermediate host, has created the currently ongoing pandemic of coronavirus disease 2019. (COVID-19) The binding assays of SARS-CoV-2 spike protein receptor binding domain disclosed enhanced affinity with human angiotensin II-converting enzyme receptor (hACE2) comparing to the bat ACE2 receptors. ACE2, is an essential component of the regulatory mechanism of the renin-angiotensin-aldosterone system, (RAAS) and this pathway is considered to interact with the pathophysiology of COVID-19. In this chapter, we will discuss the key role of RAAS in the pathogenesis of SARS-CoV-2.

Advanced Optical Technologies in Food Quality and Waste Management
Authors: Chauvin John , Duran Ray , Ng Stanley , Burke Thomas , Barton Kenneth , MacKinnon Nicholas , Tavakolian Kouhyar , Akhbardeh Alireza , Vasefi Fartash
Published: July 2021

Food waste is a global problem caused in large part by premature food spoilage. Seafood is especially prone to food waste because it spoils easily. Of the annual 4.7 billion pounds of seafood destined for U.S. markets between 2009 and 2013, 40 to 47 percent ended up as waste. This problem is due in large part to a lack of available technologies to enable rapid, accurate, and reliable valorization of food products from boat or farm to table. Fortunately, recent advancements in spectral sensing technologies and spectroscopic analyses show promise for addressing this problem. Not only could these advancements help to solve hunger issues in impoverished regions of the globe, but they could also benefit the average consumer by enabling intelligent pricing of food products based on projected shelf life. Additional technologies that enforce trust and compliance (e.g., blockchain) could further serve to prevent food fraud by maintaining records of spoilage conditions and other quality validation at all points along the food supply chain and provide improved transparency as regards contract performance and attribution of liability. In this chapter we discuss technologies that have enabled the development of hand-held spectroscopic devices for detecting food spoilage. We also discuss some of the analytical methods used to classify and quantify spoilage based on spectral measurements.

The ‘Neuromarketing’ is emerged from the realms of ‘Neuro Science’ as a new dawn and digi-driven disruption in the arena of ‘Marketing Research’ that studies the cognitive and emotional brain responses to marketing stimuli. The ‘Consumer Neuro Science’ by instigating brain wave tools figuring out what customers’ thoughts and brain responses are towards a product, service, advertisement, or even packaging. Neuromarketing mapping the activities in specific regional strata of the brain, capturing and predicting the psychological as well as physiological behavioral changes of buyers and/or consumers at a point-of-sale. The chapter intends to present the conceptual focus of ‘Buying Brain’ viz., Neuro Marketing, the role of ‘Memes’ in buying decisions, besides the tools and techniques adopted in persuading Buyers as Consumers and/or Prosumers that remain unearthed and unexplored.
Pharmacovigilance in Older Adults
Authors: Gomes Daniel , Rebelo Gomes Eva , Ribeiro-Vaz Inês , Teresa Herdeiro Maria , Roque Fátima
Published: July 2021

Polypharmacy and physiological changes inherent to the aging process can cause significant modifications in the pharmacokinetic and dynamic regimens of drugs, making the elderly more susceptible to adverse drug effects. Adverse drug reactions (ADR) in older adults have a significant impact on hospital admissions, increasing hospital stay and healthcare costs. Most common ADR in this population are dose-related and predictable. However, they can be difficult to diagnose as they often have nonspecific symptoms. This could be minimized by decreasing the use and prescription of potentially inappropriate medication and being aware of possible drug interactions. Besides, being older patients underrepresented in clinical trials and due to their physiological modifications, serious or atypical ADR are more common in this age range. To minimize harm in older adults, effective pharmacovigilance must be encouraged.
Apical Rooted Cuttings Revolutionize Seed Potato Production by Smallholder Farmers in the Tropics

Published: July 2021

Potato apical rooted cuttings (ARC) originating from juvenile simple rounded leaf mother plants are a significant new way of transplanting and field growing of seed potatoes under smallholder field conditions in the tropical highlands. The aim of this paper is to highlight the development of the technology by researchers and farmers in Vietnam, Philippines, Kenya and Uganda. The development of cultivars with late blight resistance for which no source of tuber seed was available stimulated the creation of using ARC. The demystification of tissue culture by the 1980s greatly aided this development. The key hurdle was to multiply tissue culture plants in beds of growing media and maintain the physiological young stage of the mother plants from which apical cuttings could be repeatedly taken for several months to produce ARC for sale to farmers who demanded the new cultivars (cvs) with all the desirable attributes. The technology was first developed in warmer climates at lower elevations of less than 1,500 meters above mean sea level (mamsl) but gradually it was successfully developed at cooler climates in East Africa. The technology is well established in the highlands of Vietnam and Philippines. The largest family operation is producing over 4 million ARC annually. These high-quality ARC along with improved cvs have markedly improved yields of smallholder farmers, improving food security and increasing their income levels. In Kenya and Uganda there is a rapid adoption of ARC by seed producers, smallholder farmers and youths. The ARC revolution is bringing a great deal of excitement and promise of prosperity to remote poor highland communities.
Hydroids (Cnidaria, Hydrozoa) from the Vema and Valdivia seamounts (SE Atlantic)
Authors: Gil Marta , Ramil Fran
Published: July 2021

In this report, we analyse the benthic hydroids collected on the Vema and Valdivia seamounts during a survey conducted in 2015 in the SEAFO Convention Area, focused on mapping and analysing the occurrence and abundance of benthopelagic fish and vulnerable marine ecosystem (VMEs) indicators on selected Southeast Atlantic seamounts. A total of 27 hydroid species were identified, of which 22 belong to Leptothecata and only five to Anthoathecata. Monostaechoides gen. nov. was erected within the family Halopterididae to accommodate Plumularia providentiae Jarvis, 1922, and a new species, Monotheca bergstadi sp. nov., is also described. Campanularia africana is recorded for the first time from the Atlantic Ocean, and the Northeast Atlantic species Amphinema biscayana, Stegopoma giganteum and Clytia gigantea are also recorded from the South Atlantic. Three species were identified to the genus level only, due to the absence of their gonosomes. None of the reported species are endemic, and the hydroid community is clearly dominated by species with a wide geographical distribution in the three major oceans. Only Monotheca bergstadi sp. nov. presently has its distribution restricted to the Vema Seamount and the South African coast.
A Comparison of the Clinical, Viral, Pathologic, and Immunologic Features of Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and Coronavirus 2019 (COVID-19) Diseases
Authors: Barth Rolf F. , Buja L. Maximillian , Barth Alison L. , Carpenter David E. , Parwani Anil V.
Published: July 2021

Context.—

The purpose of this review was to compare 3 coronavirus diseases, including severe acute respiratory syndrome, Middle East respiratory syndrome, and COVID-19 caused by SARS-CoV, MERS-CoV, and SARS-CoV-2 viruses, respectively.

Objective.—

To cover the following topics: clinical considerations, viral characteristics, pathology, immune response, pathogenesis, and the prognosis associated with each coronavirus disease in humans.

Data Sources.—

Clinically, flu-like symptoms are usual at the time of presentation for all 3 diseases, but these vary from asymptomatic to severe multisystem involvement. The pathology associated with symptomatic severe acute respiratory syndrome and COVID-19 has been well described, the most prominent of which is diffuse alveolar damage. The immune response to each of these viruses is highly complex and includes both humoral and cellular components that can have a significant impact on prognosis. In severe cases of COVID-19, a dysregulated innate host immune system can initiate a hyperinflammatory syndrome dominated by endothelial dysfunction that can lead to a hypercoagulable state with microthrombi, resulting in a systemic microvascular and macrovascular disease.

Conclusions.—

The severe acute respiratory syndrome and Middle East respiratory syndrome epidemics have been limited, involving approximately 8000 and 2500 individuals, respectively. In contrast, COVID-19 has resulted in a worldwide pandemic with more than 177 million cases and 3.9 million deaths as of June 15, 2021, and fatality rates ranging from less than 0.1% to approximately 10% depending upon the country. Ending on a positive note, the development of a number of vaccines, at least 6 of which now are in clinical use, should mitigate and eventually control the devastating COVID-19 pandemic.

Authors: Park Sang Yoong , Choi So Ron , Kim Jeong Ho , Lee Seung Cheol , Jeong Seong Yeop , Jeong Joon Ho , Lee Tae Young
Published: July 2021

Objectives Body protective compound-157 (BPC-157) is a stable gastric pentadecapeptide that has been effective in trials aiming to increase wound healing capabilities and decrease inflammatory cell influx, including studies on the healing of muscles and tendons. There are no studies about the effect of BPC-157 on pain transmission via nociception. This study examined the antinociceptive effects of BPC-157 using formalin tests and immunohistochemistry. Methods Rats were randomly divided into the control, morphine and BPC-157 groups. Pain behavior was quantified periodically at 5- and 35- min intervals (representative values of phases 1 and 2) by counting the number of flinches exhibited by the injected paw after injection. The dorsal root ganglia (DRG) and spinal cords (SC) were collected, and then, the number of cytokine-positive cells was determined via immunostaining. Results BPC-157 dose-dependently decreased the number of flinches during phase 1 but did not decrease the number of flinches during phase 2. During phase 1, interleukin-1β (IL-1β) in the DRG tissue was significantly different in the morphine, 10 μg/kg BPC-157, and 20 μg/kg BPC-157 groups. During phase 2, statistical significance was achieved in the DRG tissue in the morphine, 20 μg/kg BPC-157, and 40 μg/kg BPC-157 groups. During phase 1, interleukin-6 was significantly different in the DRG tissue in the morphine group and the SC tissue in the 10 μg/kg BPC-157 group. During phase 2, statistical significance was achieved in the morphine group and the BPC-157 20 μg/kg group in both the DRG and SC tissues. There were no significant differences in tumor necrosis factor-α between the DRG and SC tissues. Conclusions BPC-157 was effective during phase 1 but not during phase 2, as determined by the formalin test. BPC-157 decreased the expression of IL-1β in the DRG tissue in phases 1 and 2.
Unusual Magnetic Resonance Imaging Findings Contrast-induced Encephalopathy following Cerebral Angiography
Authors: Cho Won Ho , Lee Jung Hwan , Lee Tae Hong , Choi Chang Hwa , Ko Jun Kyeung
Published: July 2021

Contrast-induced encephalopathy (CIE) following cerebral angiography has similar clinical presentations to ischemic complications of cerebral angiography. Neurologic deficits in CIE are mostly transient, but those caused by acute cerebral infarction (ACI) as ischemic complications of cerebral angiography may be permanent. Therefore, distinguishing CIE from ACI is important. Diffusion restriction on magnetic resonance imaging (MRI) implies ACI, while hyperintensity on diffusion weighted imaging (DWI) without correlation on the apparent diffusion coefficient (ADC) map implies CIE. We reported a rare case of CIE with diffusion restriction on MRI following cerebral angiography that mimicked MRI findings of ACI. The mechanism of this phenomenon remains unknown and requires further investigation.
Modernisation de la théorie de l’État de Bergeron grâce à une étude de cas sur les amish du vieil ordre de l’Ontario1
Authors: Couture Gagnon Alexandre , Marquis-Bissonnette Maude
Published: July 2021

La théorie de l’État de Bergeron permet d’étudier les relations entre la gouverne de l’État et les citoyens. Nous revisitons la prémisse de Gérard Bergeron selon laquelle tous les membres de la société se politifient, c’est-à-dire passent de relations purement civiles à une certaine activation de la gouverne. Pour ce faire, nous étudions les amish du vieil ordre de l’Ontario. Ce groupe offre un exemple de social non politifié, concept mentionné une seule fois dans l’oeuvre de Bergeron. Grâce à l’étude de deux politiques ontariennes, la présente recherche démontre que ce groupe réfute l’adhésion inéluctable à la politie. Nous suggérons une piste pour moderniser la théorie de Bergeron.
Mouvements sociaux, politique des partis et l’évolution du nationalisme hongkongais
Authors: Dupré Jean-François
Published: July 2021

Ce texte se penche sur l’émergence et l’évolution du nationalisme hongkongais dans le contexte de la politique des partis et de la politique contestataire au cours des dernières années. Identifiant d’une part des effets de polarisation et de fragmentation du système des partis, et d’autre part un élargissement des revendications identitaires, ce texte trace le processus par lequel le nationalisme hongkongais a évolué à partir de mouvements ethnicistes vers une idéologie plus multidimensionnelle et à prépondérance civique. Il maintient que, dans un premier temps, l’institutionnalisation de ces mouvements en partis politiques, en réponse à l’échec du processus de démocratisation en 2014, a nécessité l’adoption de plateformes à la fois plus nuancées et pragmatiques leur permettant de compétitionner avec les partis pan-démocrates, entraînant une maturation des revendications identitaires hongkongaises dans leur ensemble. Dans un second temps, la répression des partis nationalistes par le gouvernement a forcé leur retour à la politique de rue, permettant la consolidation d’une alliance multiniveau entre les forces démocratiques et plus radicales contre l’emprise grandissante de Pékin et l’autoritarisme montant du gouvernement hongkongais.
Le multiculturalisme est-il relativiste ?
Authors: Côté-Vaillancourt François , Maclure Jocelyn
Published: July 2021

Pointé du doigt comme responsable d’un affaiblissement des valeurs et des identités communes, le multiculturalisme est devenu un repoussoir au sein de l’opinion publique de nombreuses sociétés. Dans cet article, nous analysons en quatre parties cette association récurrente du multiculturalisme au relativisme. Nous commençons par esquisser une analyse conceptuelle du relativisme pour évaluer dans la partie suivante si le multiculturalisme est effectivement relativiste dans ses fondements, en nous rapportant à la philosophie politique à sa source. Nous évaluons ensuite si le multiculturalisme est effectivement relativiste dans son application, à travers les politiques publiques et le droit. Finalement, nous évaluons si, sans être strictement relativiste, le multiculturalisme ne mène pas néanmoins à un déséquilibre du droit par le biais d’une survalorisation de la liberté de religion.
Réseaux d’alliances entre féministes québécoises : une relecture de la notion de « triangle de velours »
Authors: Lamoureux Diane , Mayer Stéphanie
Published: July 2021

Cet article a pour objectif d’évaluer la portée descriptive de la notion de « triangle de velours » pour comprendre la réussite de certaines collaborations féministes avec l’État québécois. La notion de triangle de velours a été élaborée par Alison Woodward en 2003 avec la volonté de rendre compte des alliances établies entre les féministes de la base, les expertes universitaires et les féministes dans les appareils d’État afin d’incorporer les luttes pour l’égalité dans les politiques publiques. Cette notion sera mise à profit dans le contexte québécois pour rendre compte de la complexité et de l’étendue des alliances parmi les féministes dans cadre des luttes pour la liberté d’avortement et l’équité salariale. Les matériaux principaux de notre analyse sont des entretiens semi-dirigés portant sur les récits de féministes militantes engagées dans ces luttes au Québec.

Cet article présente la théorie castoriadienne du sujet politique et la rapporte à son contexte politique d’énonciation, à savoir l’essor des « nouveaux mouvements sociaux » (NMS) à partir des années 1960. La thèse défendue par l’auteur est que la figure castoriadienne du sujet politique comme « peuple instituant » permet de jeter un regard nouveau sur les NMS. D’un côté, elle permet de les décrire en explicitant leur raison commune comme créativité institutionnelle. D’un autre côté, elle permet d’apprécier normativement l’ambiguïté suscitée par leur recentrement historique autour de la revendication de droits subjectifs égalitaires. Les deux premiers temps de l’article sont consacrés au commentaire de la figure castoriadienne du « peuple instituant », que l’auteur prend soin de distinguer du « peuple constituant », tandis que la troisième partie de l’article la rapporte aux NMS dans une perspective à la fois descriptive, critique et normative.

It is undisputed that complex networks are used to describe the interaction between large-scale complex systems. Different edges have different effects on network controllability. When some edges in a network are attacked or destroyed, the network controllability may be affected very little; when some other edges are attacked, network controllability may be affected very greatly, even results in the uncontrollability of the network. Which edges failure will affect the network controllability? To solve this problem, according to the node classification and edge classification, the concept of quasi-critical edge set is proposed, and the judgment theorem of quasi-critical edge set is given in this paper. In order to study the influence of quasi-critical edge set on the network controllability, the failure model of quasi-critical edge set is proposed, and the network controllability is quantified by the ratio of the number of driver nodes to the number of network nodes. In this failure model, the quasi-critical edge set with the minimum number of edges is removed first, thus destroying the network controllability quickly. By analyzing the failure model of quasi-critical edge set, the failure curve of quasi-critical edge set is obtained. It is found that the failure curve is a piecewise linear function and that the maximum (initial) slope of failure curve is related to the average degree of network. In addition, the failure of quasi-critical edge set has the greatest influence on network controllability. A comparison among the failure of quasi-critical edge set, random failure, degree failure, and betweenness failure verifies that the failure of quasi-critical edge set has the greatest damage to the network controllability in both model networks (ER random network, BA scale-free network, random triangle network and random rectangle network) and real networks in 26 different fields. For some of real networks, such as cancer cell networks, terrorist communication networks and other networks that are harmful to human beings, the failure model of quasi-critical edge set can provide a reference attack method.

The effects of temperature and baryon chemical potential on equation of state and thermodynamics of isospin imbalanced QCD matter are investigated in the framework of two-flavor Nambu−Jona-Lasinio model. The equation of state at zero temperature and baryon chemical potential as well as the isospin density and normalized pressure at finite temperature are shown to be consistent with the lattice data. We also find that the energy per isospin increases monotonically with the increase of isospin density at vanishing temperature and baryon chemical potential, while it first decreases and then increases with the augment of isospin density, behaving as a non-symmetric parabolic curve. Finally, we compute the sound velocity and find that it is discontinuous at the phase transition point for finite temperature and/or baryon chemical potential. In particular, the sound velocity in the superfluid phase is distinctly larger than that in the ordinary nuclear matter and quark matter, while the temperature and baryon chemical potential included in the superfluid phase makes the equation of state softer and the sound velocity slower.

The major challenge of spintronics lies in how to generate, manipulate, and detect spin current. Multiple methods, such as using magnetic materials, magnetic field, and polarized light field to manipulate the spin of electrons, have been proposed. Owing to the possible applications in spintronic devices, there is currently great interest in the field of spin caloritronics, which focuses on the interplay of spin and heat currents. Stanene is a type of two-dimensional topological insulator consisting of a single layer of Sn atoms arranged in a hexagonal lattice. In this paper, the effects of light and electric fields on the spin-dependent thermoelectric effect of the stanene nanoribbon are studied theoretically based on the non-equilibrium Green’s function method. The results show that the properties and intensity of the thermoelectric current can be effectively controlled by the intensity and the polarization direction of the circularly polarized light field. Under the joint action of a strong circularly-polarized light field and an electric field, the stanene can transform from a quantum spin-Hall insulator into a spin-polarized quantum Hall insulator. When the left-circularly-polarized light field is applied, the spin-down edge states of stanene undergo a phase transition to form a bandgap, and a 100% spin-polarized spin-down current driven by temperature gradient can be obtained. When the right-circularly-polarized light is applied, the edge states of spin-up electrons are destroyed, and a completely polarized spin-up thermal current can be generated. In the weak external field, the properties of the edge state do not change, and the system does not output a thermoelectric current. In addition, the study shows that the intensity of the thermal spin current is related to the width of the bandgap, and a moderate increase in temperature can significantly increase the peak value of the current, but the higher equilibrium temperature and temperature gradient will restrain the spin thermoelectric effect.
Propelling and perturbing appendages together facilitate strenuous ground self-righting

Published: July 2021

Terrestrial animals must self-right when overturned on the ground, but this locomotor task is strenuous. To do so, the discoid cockroach often pushes its wings against the ground to begin a somersault which rarely succeeds. As it repeatedly attempts this, the animal probabilistically rolls to the side to self-right. During winged self-righting, the animal flails its legs vigorously. Here, we studied whether wing opening and leg flailing together facilitate strenuous ground self-righting. Adding mass to increase hind leg flailing kinetic energy increased the animal’s self-righting probability. We then developed a robot with similar strenuous self-righting behavior and used it as a physical model for systematic experiments. The robot’s self-righting probability increased with wing opening and leg flailing amplitudes. A potential energy landscape model revealed that, although wing opening did not generate sufficient kinetic energy to overcome the high pitch potential energy barrier to somersault, it reduced the barrier for rolling, facilitating the small kinetic energy from leg flailing to probabilistically overcome it to self-right. The model also revealed that the stereotyped body motion during self-righting emerged from physical interaction of the body and appendages with the ground. Our work demonstrated the usefulness of potential energy landscape for modeling self-righting transitions.
Increased influence of prior choices on perceptual decisions in autism

Autism spectrum disorder (ASD) manifests sensory and perceptual atypicalities. Recent theories suggest that these may reflect a reduced influence of prior information in ASD. Some studies have found reduced adaptation to recent sensory stimuli in ASD. However, the effects of prior stimuli and prior perceptual choices can counteract one-another. Here, we investigated this using two different tasks (in two different cohorts): (i) visual location discrimination and (ii) multisensory (visual-vestibular) heading discrimination. We fit the data using a logistic regression model to dissociate the specific effects of prior stimuli and prior choices. In both tasks, perceptual decisions were biased toward recent choices. Notably, the ‘attractive’ effect of prior choices was significantly larger in ASD (in both tasks and cohorts), while there was no difference in the influence of prior stimuli. These results challenge theories of reduced priors in ASD, and rather suggest an increased consistency bias for perceptual decisions in ASD.

Most eukaryotic mRNAs accommodate alternative sites of poly(A) addition in the 3’ untranslated region in order to regulate mRNA function. Here, we present a systematic analysis of 3’ end formation factors, which revealed 3’UTR lengthening in response to a loss of the core machinery, whereas a loss of the Sen1 helicase resulted in shorter 3’UTRs. We show that the anti-cancer drug cordycepin, 3’ deoxyadenosine, caused nucleotide accumulation and the usage of distal poly(A) sites. Mycophenolic acid, a drug which reduces GTP levels and impairs RNA polymerase II (RNAP II) transcription elongation, promoted the usage of proximal sites and reversed the effects of cordycepin on alternative polyadenylation. Moreover, cordycepin-mediated usage of distal sites was associated with a permissive chromatin template and was suppressed in the presence of an rpb1 mutation, which slows RNAP II elongation rate. We propose that alternative polyadenylation is governed by temporal coordination of RNAP II transcription and 3’ end processing and controlled by the availability of 3’ end factors, nucleotide levels and chromatin landscape.
