AbstractObjectivesTo investigate the clinicopathological features, BRAF V600E mutation, and MAML2 rearrangement of ameloblastoma with mucous cell differentiation.Materials and MethodsFive cases of ameloblastoma with mucous cell differentiation were retrospectively studied. Clinicopathological features, BRAF V600E mutation, and MAML2 rearrangement were analyzed. Follow‐up information was available for all cases.ResultsOf five cases, two cases were male and three were female, aged 18–55 years. Four cases were located in the mandible and one case in the maxilla. Histologically, four of the five cases (80%) presented with cystic features and three of the five cases (60%) with varying degrees of squamous metaplasia. The mucous cells were located in the epithelial islands or the luminal aspect of the cystic cavities. The BRAF V600E mutation was found in three of five cases (60%). All the cases showed no MAML2 rearrangement. Two cases were recurrent lesions, and one case had a local recurrence during the follow‐up.ConclusionsAmeloblastoma with mucous cell differentiation is closely related to the cystic features, squamous metaplasia, and shows a high prevalence of BRAF V600E mutation. The absence of MAML2 rearrangement reveals that ameloblastoma with mucous cell differentiation and central mucoepidermoid carcinoma (MEC) are two distinct tumor entities.

AbstractBackgroundMedical technologies for consumers aim to help prevent, manage, and even forecast cardiovascular events, but their emotional impact is not fully known. The value of mobile‐electrocardiogram (mECG) technology to an existing group of cardiac patients is unknown. The purpose of this study was to examine the impact of readily available mECG capability for a sample of implantable cardioverter defibrillator (ICD) patients.MethodsPatients with ICDs (N = 51) were recruited and consented in a large academic cardiology clinic. Participants were given a mECG device and asked to take a 30‐ss reading at least once per day for 30 days. Technology satisfaction, cardiac anxiety, shock anxiety, and ICD device acceptance were measured pre‐ and post‐mECG usage.ResultsmECG technology was regularly used (M = 36.6 readings completed per month) and positively appraised by ICD patients (mean of 4.4 out of possible 5). Self‐reported symptoms of general cardiac anxiety were not significantly affected by the utilization of mECG technology. ICD specific measures were mixed with increased overall ICD device acceptance but also increased shock anxiety.ConclusionsICD patients positively viewed and used mECG technology regularly as prescribed. However, the overall psychological impact of mECG was mixed and suggests that ICD patients may have idiosyncratic adjustments to the increased access of cardiac device data.

AbstractHigh CO2 concentrations stimulate net photosynthesis by increasing CO2 substrate availability for Rubisco, simultaneously suppressing photorespiration. Previously, we reported that silencing the chloroplast vesiculation (cv) gene in rice increased source fitness, through the maintenance of chloroplast stability and the expression of photorespiration‐associated genes. Because high atmospheric CO2 conditions diminished photorespiration, we tested whether CV silencing might be a viable strategy to improve the effects of high CO2 on grain yield and N assimilation in rice. Under elevated CO2, OsCV expression was induced, and OsCV was targeted to peroxisomes where it facilitated the removal of OsPEX11‐1 from the peroxisome and delivered it to the vacuole for degradation. This process correlated well with the reduction in the number of peroxisomes, the decreased catalase activity and the increased H2O2 content in wild‐type plants under elevated CO2. At elevated CO2, CV‐silenced rice plants maintained peroxisome proliferation and photorespiration and displayed higher N assimilation than wild‐type plants. This was supported by higher activity of enzymes involved in NO3− and NH4+ assimilation and higher total and seed protein contents. Co‐immunoprecipitation of OsCV‐interacting proteins suggested that, similar to its role in chloroplast protein turnover, OsCV acted as a scaffold, binding peroxisomal proteins.
Category‐based attentional capture can be influenced by color‐ and shape‐dimensions independently in the conjunction search task

AbstractAttention can be involuntarily attracted by a distractor that matches the current attentional control settings (ACSs). However, it remains unclear whether two category‐specific ACSs can operate independently. By defining a target as a combination of two prototype‐based categories, the present event‐related potential (ERP) study investigated how color‐category and shape‐category ACSs operate within a search task paradigm and the effects of temporal task demands on these ACSs. The matching level between target and distractor was manipulated to separate the effects of each ACS. The relative position between target and distractor was employed to isolate the attentional processing of the distractor from the target. Furthermore, two display durations were used to manipulate the temporal task demands, including a short fixed window (800 ms) and a dynamic window extended until the user responded. Our results support a two‐stage selection scenario. In early stage, the color‐ and shape‐ACS independently guided attention to task‐relevant property (N2pc components) and suppressed attention toward task‐irrelevant properties (PD components). In late stage, these two independent ACSs were integrated into a holistic ACS to interfere with the consolidation (contralateral delay activity components) and behavioral performance (accuracy and RTs) of target identification. Moreover, an early N1/P1 component might reflect a preattentive enhancement of relevant information or a preattentive suppression of irrelevant objects. These two category‐specific ACSs weights differently in varied temporal task demands. These findings support the idea that independent early processing is followed by integrated late processing, which can be applied to category‐based attentional capture with different temporal task demands.
Who are you talking to? The role of addressee identity in utterance comprehension

Published: January 2020

AbstractExperimental evidence suggests that speaker and addressee quickly adapt to each other from the earliest moments of sentence processing, and that interlocutor‐related information is rapidly integrated with other sources of nonpragmatic information (e.g., semantic, morphosyntactic, etc.). These findings have been taken as support for one‐step models of sentence comprehension. The results from the present event‐related potential study challenge this theoretical framework providing a case where discourse level information is integrated only at a late stage of processing, when morphosyntactic analysis has been already initiated. We considered the case of Basque allocutive agreement, where information about addressee gender is encoded in verbal inflection. Two different types of Basque grammatical violations were presented together with the corresponding control conditions: one could be detected based on a morphosyntactic mismatch (person agreement violation), while the other could be detected only if the addressee's gender was considered (allocutive violation). Morphosyntactic violations elicited greater N400 effects followed by P600 effects, while allocutive violations elicited only P600 effects. These results provide new constraints to one‐step accounts as they represent a case where speakers do not immediately adjust to the addressee's perspective. We propose that the relevance of discourse‐level information might be a crucial variable to reconcile the dichotomy between one‐ and two‐step models.
Acute stress impairs reward positivity effect in probabilistic learning
Authors: Zhang Xukai , Li Peng , Chen Jie , Li Hong 
Published: January 2020

AbstractDecision making based on feedback learning requires a series of cognitive processes, including estimating the probability of particular outcomes and modulating expectations between expected versus actual outcomes. It has been suggested that stress affects decision making and subsequent processing of feedback valence and magnitude. However, less is known about the effect of acute stress on reward expectancy. In the current study, participants performed a probabilistic learning task, in which they learned an association between response and feedback within different reward expectancy trials (30% and 70%) under the conditions of stress (threat of shock) and safety (no shock). We recorded event‐related potentials (ERPs) to measure the reward positivity (RewP) which reflects reward prediction error signals during feedback processing. Behavioral data indicated that participants performed better in the 70% reward trials than in the 30% reward trials. However, no significant difference was observed between stress and safe conditions. Importantly, ERP results indicated that unexpected feedback elicited larger RewP than did expected feedback and this expectancy effect of RewP was reduced in the stress relative to safe condition. Moreover, the correlations between RewP and choice accuracy (70% − 30% reward condition) in the safe and stress conditions were in a similar pattern; yet, only in the stress condition the correlation reached significantly. This may indicate that blunted RewP was associated with impaired performance at an individual level. Our study provides ERP evidence that acute stress affects brain responses to reward prediction error processing, which may explain various abnormal learning behaviors associated with stress‐related disorders.

AbstractModern cemented intervals (beachrock, firmgrounds to hardgrounds and concretionary layers) form in the lagoon and intertidal sabkha of Abu Dhabi. Seafloor lithification actively occurs in open, current‐swept channels in low‐lying areas between ooid shoals, in the intertidal zone of the middle lagoon, some centimetres beneath the inner lagoonal seafloor (i.e. within the sediment column) and at the sediment surface the intertidal sabkha. The concept of ‘concretionary sub‐hardgrounds’, i.e. laminar cementation of sediments formed within the sediment column beneath the shallow redox boundary, is introduced and discussed. Based on calibrated radiocarbon ages, seafloor lithification commenced during the Middle to Late Holocene (ca 9000 cal yr bp), and proceeds to the present‐day. Lithification occurs in the context of the actualistic relative sea‐level rise shifting the coastline landward across the extremely low‐angle carbonate ramp. The cemented intervals are interpreted as parasequence boundaries in the sense of ‘marine flooding surfaces’, but in most cases the sedimentary cover overlying the transgressive surface has not yet been deposited. Aragonite, (micritic) calcite and, less commonly, gypsum cements lithify the firmground/hardground intervals. Cements are described and placed into context with their depositional and marine diagenetic environments and characterized by means of scanning electron microscope petrography, cathodoluminescence microscopy and Raman spectroscopy. The morphology of aragonitic cements changes from needle‐shaped forms in lithified decapod burrows of the outer lagoon ooidal shoals to complex columnar, lath and platy crystals in the inner lagoon. Precipitation experiments provide first tentative evidence for the parameters that induce changes in aragonite cement morphology. Data shown here shed light on ancient, formerly aragonite‐cemented seafloors, now altered to diagenetic calcites, but also document the complexity of highly dynamic near coastal depositional environments.
The Curious Case of Cú Chulainn: Nationalism, Culture, and Meaning‐Making in the Contested Symbols of Northern Ireland
Authors: Goalwin Gregory J. 
Published: January 2020

AbstractThis article examines the ways that political movements utilize contested imagery to further ideological goals. While scholars have long recognized the importance of symbols for nationalism, most analyses rely on national symbols being relatively unambiguous. I seek to understand how such processes function when this is not the case, examining how organizations on both sides of the conflict in Northern Ireland deployed the same symbol – representations of the Irish hero Cú Chulainn – to support diametrically opposed political programmes. I argue that the different movements in Northern Ireland imbued symbols such as Cú Chulainn with their own meaning by emplotting them within their ideological narratives. These narratives shaped and gave significance to visual symbols, producing myths that sought to structure the ways members of society viewed the world. In return, these symbols and myths provided evidence which reciprocally strengthened and supported the ideological narratives of the movements that produced them, serving as potent reminders of the ideological worldview such narratives advocate.
A Month under Occupation: The State against Society
Authors: Bajoria Rishabh 
Published: January 2020

AbstractThese field notes present personal reflections and observations from the author's visit to Srinagar in June 2017, where he was working as an intern with the Association of Parents of Disappeared Persons. The author's nascent understanding of India's attempts to assimilate the Kashmir Valley into the Indian Union was heavily influenced by the 2016 uprising in the Valley following the death of the Hizbul Mujahideen commander, Burhan Muzzafar Wani. The paper argues that the spatial manifestations of Indian occupation stimulate resistance among Kashmiris rather than engendering submission.
Social Media and the Dynamics of Radicalization and Violent Extremism among Female Migrant Workers
Authors: Mansour‐Ille Dina 
Published: January 2020

AbstractFemale migrant workers, especially domestic workers, have often been portrayed as victims of exploitation, abuse, violence, and marginalization in the literature. In recent years, however, reports on the radicalization of female migrant workers and their engagement in terrorism have started to emerge. Female migrant workers, who were otherwise only nominally religious before migrating for work, are reportedly embracing radicalized forms of religion and violence after being exposed to extremist content on social media. This paper sheds light on this phenomenon in relation to the widespread use of social media. It fits within an emerging body of literature that is beginning to portray these workers as agents for change and of their own destiny rather than helpless subjects and victims of exploitation. The paper examines the role of religion and religious institutions as a means for coping as well as for empowerment, emancipation, and resistance. It also questions the interlinkages between the feminization of international labour migration and violent extremism, and it calls for more research on the lived experiences of vulnerable female workers in order to better understand the complex and multifaceted dynamics of radicalization and violent extremism within the context of migration, especially in relation to the role of technology.
Unconventional economic policies and sentiment: An international assessment
Authors: Gagnon Marie‐Helene , Gimet Celine 
Published: January 2020

AbstractThis paper estimates, using Bayesian and global VARs, the spillover effects of unconventional fiscal and monetary policies implemented in the United States and in the Eurozone during the last decade. Consumer confidence and investor sentiment indicators are introduced in the models in order to highlight the signalling channel in the responses to economic policy innovations in times of crisis. Our results reveal that consumer and investor perceptions of innovative economic measures are relevant to study the pass‐through of economic policies to the real sector in times of crisis and zero lower bound interest rates. In particular, the signalling channel plays an important role in successful unconventional economic policies. Moreover, if unconventional economic policies have an impact abroad, the effects are similar to those measured in the domestic country/region. Consequently, coordination and transparency are a prerequisite for ensuring short‐term growth after a global financial crisis.
Industrial policy in the era of global value chains: Towards a developmentalist framework drawing on the industrialisation experiences of South Korea and Taiwan
Authors: Hauge Jostein 
Published: January 2020

AbstractIn this paper, I present a framework for GVC‐oriented industrial policy that merges the so‐called GVC perspective and the so‐called developmentalist perspective—the latter of which is a perspective that industrial policy is most often analysed through, but has been somewhat neglected by the GVC perspective. I argue that the GVC perspective too quickly dismisses the relevance of industrial policy in the East Asian development experience, particularly those in South Korea and Taiwan between roughly 1960 and 1990. By drawing on the industrialisation experiences of these two countries, my framework for industrial policy suggests that the GVC perspective's ideas for industrial policy would be strengthened by more clearly acknowledging the continued importance of three observations by the developmentalist perspective: (a) the need for governments in developing countries to bargain with foreign investors for the purpose of domestic industrialisation; (b) policy design should not only focus on increasing exports, but also focus on replacing some imports with domestic production; and (c) linking up to the value chains of transnational corporations based in high‐income countries can bring about some benefits, but ultimately, successful industrialisation necessitates a degree of competing with transnational corporations. State‐owned enterprises have historically played an important role in this respect.
Near-Zero CO2 Emissions Power Plant Based on High Temperature Fuel Cells
Authors: Carapellucci Roberto , Cipollone Roberto , Di Battista Davide 
Published: January 2020

Abstract
The recent awareness on the environmental issues related to global warming is leading to the search for always more efficient energy conversion systems and, mainly, with very low carbon dioxide emissions. In fact, they are strictly related to the combustion reaction of fossil fuels which is the main process of the actual power generation technology. In this regard, fuel cells are energy conversion systems which are characterized by higher efficiency and near-zero CO2 emissions. Their novel integration with conventional power plants participates to the concept of the decarbonization of the economy.
In this work, the integration of two high temperature fuel cells (HTFC) with a gas turbine power plant has been proposed and investigated, thanks to the combination of a physical model of the fuel cells and a numerical one of the components involved in the gas turbine cycle. In the layout studied, fresh air is compressed, pre-heated and used in a Solid Oxide Fuel Cell (SOFC), where the high operating temperature and the exothermic process give exhaust gases at very high temperatures, suitable for an expansion in a turbine. After the expansion, the gases are rich of CO2 and, so, they can be sent to the cathode side of a Molten Carbonate Fuel Cell (MCFC). Hence, the so-defined integrated plant is composed by three power units: a turbine, a SOFC and a MCFC; operating pressure, fuel need, oxygen and carbon dioxide utilizations in the fuel cells are parameterized in order to optimize the whole plant and find additional room of energy exploitation. Moreover, the MCFC acts as an active device for carbon separation, introducing further environmental benefits.
Study of Angle-of-Attack (AoA) for Airfoil in Deterministic Lateral Displacement (DLD)
Authors: Ahasan Kawkab , Kim Jong-Hoon 
Published: January 2020

Abstract
Deterministic lateral displacement (DLD) is a method of inertial size-based particle separation with potential applications in high throughput sample processing, such as the fractionation of blood or the purification of target species like viral particles or circulating tumor cells. Recently, it has been shown that symmetric airfoils with neutral angle-of-attack (AoA) can be used for high-throughput design of DLD device, due to their mitigation of vortex effects and preservation of flow symmetry under high Reynolds number (Re) conditions. While high-Re operation with symmetric airfoils has been established, the effect of AoA for airfoil on the DLD performance has not been characterized. In this study, we present a high-Re investigation with symmetric airfoil-shaped pillars having positive and negative 15 degree AoA. Both positive and negative AoA configurations yield significant flow anisotropy at higher flow rates. The stronger shift of the critical diameter (Dc) was observed with negative AoA, but not in positive AoA device. The most likely contributor may be the growing anisotropy that develops in the AoA device at higher flow rates. This study shows that high-Re DLD design with airfoil shaped pillars requires significant consideration for pillar orientation to control flow symmetry.
