Augmenting Maneuverability of UUVs with Cycloidal Propellers

This paper investigates a novel concept of using cycloidal propellers to augment the maneuverability of unmanned underwater vehicles. Cycloidal propellers are cross-flow propellers that utilize 360$^{\circ}$ thrust vectoring to provide agile maneuvering to surface vessels like yachts, tug boats, buoy tenders and double ended ferries, but have yet to be utilized on present-day unmanned and autonomous marine vehicles. Through 360$^{\circ}$ thrust vectoring, cycloidal propellers enable surface vessels to execute spot turns, and surge in forward and backward directions with equal ease. Such compact maneuvers are difficult to execute with the conventional screw propeller-rudder setup found on marine vehicles today. On unmanned and autonomous marine vehicles, cycloidal propellers can potentially enable controlled and decoupled maneuvering in all six degrees-of-freedom while overcoming disturbances like waves and currents, and extreme flow conditions like cavitation and ventilation. This is critical for marine vehicles operating at low speeds and in restricted waters. Therefore, the objective of this paper is to study the maneuvering characteristics of a UUV driven by a screw propeller and control fins only, and compare it to that of the UUV augmented with retractable cycloidal propellers. The cases considered are a turning circle maneuver, a low-speed 180$^{\circ}$ turn and a low-speed heave maneuver. A six degrees-of-freedom motion prediction model that accounts for the non-linear and coupled loads on an underwater vehicle is developed and validated. Simulation results showed that compared to conventional propulsion systems, cycloidal propellers could potentially enable more swift, compact and decoupled maneuvers in unmanned marine vehicles. Integrated with robust control systems, cycloidal propellers can be explored for use in dynamic positioning, ocean exploration, station-keeping, seakeeping and teaming of unmanned and autonomous marine vehicles.
Biotechnology and sustainable agriculture in Central Queensland

Within Australia, both State and Federal governments have exhibited support for biotechnology. Agriculture is currently considering whether to embrace new biotechnologies. Sustainable development means that economic growth should be promoted but guided in ways that are both environmentally benign and socially just. Does biotechnology offer new means of attaining sustainability? This paper looks at a number of biotechnology applications and evaluates their contribution to sustainable agriculture and development in the Central Queensland region. Results show that each application of the technology must be examined individually to determine its sustainability in terms of the environment, economic status and public acceptance. It concludes that the evaluation of environmental outcomes of releases in terms of current agro-environmental standards may not be sufficient to ensure the sustainability of the technology. It is necessary to question the sustainability of current agricultural practices as well.
A big data analytics based methodology for strategic decision making

The purpose of this paper is to present a novel framework for strategic decision making using Big Data Analytics (BDA) methodology. ,In this study, two different machine learning algorithms, Random Forest (RF) and Artificial Neural Networks (ANN) are employed to forecast export volumes using an extensive amount of open trade data. The forecasted values are included in the Boston Consulting Group (BCG) Matrix to conduct strategic market analysis. ,The proposed methodology is validated using a hypothetical case study of a Chinese company exporting refrigerators and freezers. The results show that the proposed methodology makes accurate trade forecasts and helps to conduct strategic market analysis effectively. Also, the RF performs better than the ANN in terms of forecast accuracy. ,This study presents only one case study to test the proposed methodology. In future studies, the validity of the proposed method can be further generalized in different product groups and countries. ,In today’s highly competitive business environment, an effective strategic market analysis requires importers or exporters to make better predictions and strategic decisions. Using the proposed BDA based methodology, companies can effectively identify new business opportunities and adjust their strategic decisions accordingly. ,This is the first study to present a holistic methodology for strategic market analysis using BDA. The proposed methodology accurately forecasts international trade volumes and facilitates the strategic decision-making process by providing future insights into global markets.
Antiproton acceleration in the Main Injector with RF at harmonic number h=28 or h=84

Antiproton bunches of 1.5 eVs are required for the Tevatron but can not be accelerated through transition in the Main Injector (MI) with the h=588 rf system. Chandra Bhat has developed parameters for h=28 acceleration from 8 GeV followed by h=588 acceleration from 25 to 150 GeV. [1] This note refines the h=28 scenario and also adapts it to the h=84 case needed for 132 ns separation. It is practicable to accelerate the 1.5 eVs {bar p} bunches in about seven seconds with no loss and less than ten percent emittance growth using the existing 2.5 MHz cavities. Both the cycle time and emittance growth are significantly improved by the scheme described in this note. Excellent results can be obtained for the 7.5 MHz case with only 75 kV except that there is a 0.5 % beam loss. For completely clean 53 MHz capture of the tail produced by shape mismatch at transition, 250 kV is desirable for bunch rotation at 26 GeV.

On the string Lie algebra Salim Rivière

We construct an abelian representative for the crossed module associated to the string Lie algebra. We show how to apply this construction in order to define quasi-invariant tensors which serve to categorify the infinitesimal braiding on the category of g-modules given by an r-matrix, following Cirio-Martins [2]. Introduction Given a simple compact simply connected Lie group G, the string group Str(G) is in some sense its 3-connected cover. There are various models for Str(G) in the literature, for example as a weak 2-group with finite-dimensional components or as a strict 2-group with infinite-dimensional components [1]. But strict 2groups are nothing else than crossed modules, thus the string group and its Lie algebra, the string Lie algebra, can be represented by crossed modules, see for example [7] for some model. Crossed modules of Lie algebras are closely related to 3-cohomology classes, and the 3-cohomology class corresponding to the string Lie algebra is the class represented by the Cartan cocycle κ([−, −], ) ∈ Z(g,C) for a simple complex Lie algebra g and its symmetric, non-degenerate bilinear Killing form κ. Introductive material on crossed modules is given in Section 1, and material on the string Lie algebra in Section 3 (closely following [7]). We want to emphasize in this article that it is interesting to find abelian representatives for a given equivalence class of crossed modules. These are crossed modules of the form μ : V2 → V3 ×α g which are spliced together from a short exact sequence of g-modules 0 → V1 → V2 d → V3 → 0 and an abelian extension V3 ×α g of g by V3 via a 2-cocycle α. We will almost always consider crossed modules where V1 = C, the trivial g-module. The construction of abelian representatives stems back to [8] and is recalled here in Section 2.
Transnational representation of a gendered recession in corporate dramas

The cinematic depiction of the financial crisis has centred on the explanation of the causes and consequences of the global recessionary scenario in which gender acquires special relevance. My aim in this article is to carry out a hitherto unaddressed transnational analysis of corporate dramas. More specifically, I elicit the commonalities as well as local specificities that different Western cinematographies show when tackling gendered recessionary discourses on ‘mancession’ and ‘austerity’. Films such as The Last Days of Lehman Brothers (Samuels, 2009, BBC), Money Never Sleeps (Stone, 2010), The Company Men (J. Wells, 2010) and The Big Short (McKay, 2015) have, on the one hand, aligned with nostalgic and retro-sexist discourses by focusing on male suffering to confront the recession while relegating female characters as emotional companions of the male hero. On the other hand, the representation of female characters in these films has also put to the test the inconsistencies of neoliberal discourses when analysed from the perspective of genre. To illustrate the transnational dimension of the ‘narrated’ impact of the ‘Global Financial Crisis’ in different scenarios, I compare a US Wall Street film and a Spanish corporate drama of the Great Recession: Margin Call (J Chandor, 2011, USA) and The Tip of the Iceberg (La punta del iceberg, D Cánovas, 2016, Spain).
Mechanistic Origin of Superionic Lithium Diffusion in Anion-Disordered Li6PS5X Argyrodites

The rational development of fast-ion-conducting solid electrolytes for all-solid-state lithium-ion batteries requires understanding the key structural and chemical principles that give some materials their exceptional ionic conductivities. For the lithium argyrodites Li6PS5X (X = Cl, Br, or I), the choice of the halide, X, strongly affects the ionic conductivity, giving room-temperature ionic conductivities for X = {Cl,Br} that are ×103 higher than for X = I. This variation has been attributed to differing degrees of S/X anion disorder. For X = {Cl,Br}, the S/X anions are substitutionally disordered, while for X = I, the anion substructure is fully ordered. To better understand the role of substitutional anion disorder in enabling fast lithium-ion transport, we have performed a first-principles molecular dynamics study of Li6PS5I and Li6PS5Cl with varying amounts of S/X anion-site disorder. By considering the S/X anions as a tetrahedrally close-packed substructure, we identify three partially occupied lithium sites that define a contiguous three-dimensional network of face-sharing tetrahedra. The active lithium-ion diffusion pathways within this network are found to depend on the S/X anion configuration. For anion-disordered systems, the active site–site pathways give a percolating three-dimensional diffusion network; whereas for anion-ordered systems, critical site–site pathways are inactive, giving a disconnected diffusion network with lithium motion restricted to local orbits around S positions. Analysis of the lithium substructure and dynamics in terms of the lithium coordination around each sulfur site highlights a mechanistic link between substitutional anion disorder and lithium disorder. In anion-ordered systems, the lithium ions are pseudo-ordered, with preferential 6-fold coordination of sulfur sites. Long-ranged lithium diffusion would disrupt this SLi6 pseudo-ordering, and is, therefore, disfavored. In anion-disordered systems, the pseudo-ordered 6-fold S–Li coordination is frustrated because of Li–Li Coulombic repulsion. Lithium positions become disordered, giving a range of S–Li coordination environments. Long-ranged lithium diffusion is now possible with no net change in S–Li coordination numbers. This gives rise to superionic lithium transport in the anion-disordered systems, effected by a concerted string-like diffusion mechanism.
Contrasting responses of land-terminating glaciers to recent climate variations in King George Island, Antarctica

Abstract In this study, we aim to analyse the glacier dynamics of land-terminating glaciers in King George Island (Antarctica) between 1956 and 2018. Glacial fluctuations are estimated using space-borne remote sensing data (SPOT, Landsat, PlanetScope, Sentinel-1, Sentinel-2, WorldView-2 and TanDEM-X). The eastern sector of Warszawa Icefield witnessed continuous glacier retreat during 1979–2018 (surface loss of 30%). The decreases in the ice-covered areas of the Tower, Windy, Ecology, Baranowski and Sphinx glaciers were 70%, 31%, 25%, 25% and 21%, respectively, with their accumulation area ratios (AARs) exhibiting negative mass balances. The winter air temperature was cooler during the 1970s with warming trends in the 1980s and early 2000s followed by a cooling trend until the present day. However, the annual time series has shown high interannual variability in air temperature during these periods. We show that the AAR, dimensions, length, frontal elevation, maximum elevation, slope and changes in the terminus position influence the glacier response to climate change at various timescales. Furthermore, three geomorphic activity intensity zones and a complete paraglacial sequence are identified while contrasting the proglacial systems. Overall, subglacial deposits predominate and indicate that meltwater flows on the bed, producing wet-based thermal regimes.
Prognosis of distal pancreatic cancers controlled by stage

Patients with distal (body/tail) pancreatic cancer have been found to present worse outcome than patients with head cancer, which is generally attributed to the great proportion of advanced stages for body/tail cancers upon detection. However, differences in prognosis between head and body/tail pancreatic cancers controlled by stage have not been analyzed in-depth. In this study, differences in prognosis between head and body/tail pancreatic cancers were examined using the Surveillance, Epidemiology, and End Results Program (SEER) (1973-2014 registry, 85,715 cases). We found that patients with body/tail pancreatic cancer had worse prognosis than patients with head cancer for all combined stages [adjusted hazard ratio (HR), 1.03, 95% confidence interval (CI), 1.00-1.05, P=0.025]. Compared with patients with head cancer, patients with body/tail cancer had lower mortality for stage I cancers (HR, 0.85, 95% CI, 0.76-0.94, P=0.001), no difference in mortality for stages II or III (stage II, HR, 1.00, 95% CI, 0.95-1.06, P=0.965; stage III, 0.97, 95% CI, 0.91-1.04, P=0.398), and higher mortality for stage IV (HR, 1.07, 95% CI, 1.04-1.10, P<0.001). In addition, the proportion of body/tail pancreatic cancer increased from 24.9% in 1973 to 36.3% in 2014. Therefore, tumor location of body/tail is an independent adverse prognostic factor for patients with pancreatic cancer. However, this observation is not applicable when controlled by stage (body/tail versus head pancreatic cancer, better stage I, similar stage II/III, and worse stage IV).
A Pilot Study of the Rehabilitation Services Provided for Patients with Dysphagia in Medical Settings in Jordan

Services provided for dysphaiga conditions are poorly investigated in Jordan. The aim of this study was to explore the rehabilitation services provided to patients with dysphagia in medical settings in Jordan. Data were collected from public and private hospitals, hearing and speech centres, and rehabilitation centres located in Amman province. Thirty-eight participants (16 patients and 22 professionals from various disciplines) were interviewed. There was limited knowledge about dysphagia among healthcare professionals. The provision of rehabilitation services was minimal and secondary to the provision of medical services. Clinical pathways and guidelines need to be devised to organize the work of professionals involved in the management of dysphagia.
Satisfaction vs experienced utility: current issues and opportunities

ABSTRACT Satisfaction is one of the most studied constructs in many fields, including tourism. As an important marketing metric, satisfaction is typically measured with self-reported retrospective evaluations of travel experience. However, the memory-based approaches have numerous limitations related to social desirability, availability heuristics, previous knowledge, mood at the time of answering questions and do not reflect the moment-by-moment nature of visitor experience. The shortcomings and limitations of self-reported retrospective evaluations could be eliminated by introducing pre-visit, on-site, and post-visit instant components of experienced utility as measures of visitor experience. The experienced utility allows eliminating the majority of self-report biases, capturing the affective components of visitor experience, analysing relationships between anticipation, experienced, and remembered utilities, and applying emerging moment-based research techniques. Therefore, this manuscript proposes a measurable definition of experienced utility and appropriate measures to assess visitor experience.
Self-Disclosure Here and Now: Combining Retrospective Perceived Assessment With Dynamic Behavioral Measures

Most previous research on self-disclosure (SD) focused on its perceived retrospective aspects using self-report questionnaires. Few studies investigated actual SD as reflected in interpersonal interaction. We propose a comprehensive approach that combines new objective and dynamic measures of SD that evaluate situated SD with the traditional measures that evaluate stable SD properties. As SD is essentially verbal, we build on linguistic parameters for assessing actual SD, including acoustic features such as intonation and fluency, and verbal features such as the particular choice of words. Critically, the new measures highlight SD here and now and may reveal transient situational factors that affect it, such as the dynamics of interpersonal interaction. Based on these measures, we propose a three-dimensional evaluation that can portray different profiles of SD and offer a better prediction of SD behavior in different situations. The theoretical and clinical implications of the proposed approach are discussed.
The Sense of Sounds: Brain Responses to Phonotactic Frequency, Phonological Grammar and Lexical Meaning

Two outstanding questions in spoken-language comprehension concern (1) the interplay of phonological grammar (legal vs. illegal sound sequences), phonotactic frequency (high- vs. low-frequency sound sequences) and lexicality (words vs. other sound sequences) in a meaningful context, and (2) how the properties of phonological sequences determine their inclusion or exclusion from lexical-semantic processing. In the present study, we used a picture-sound priming paradigm to examine the ERP responses of adult listeners to grammatically illegal sound sequences, to grammatically legal sound sequences (pseudowords) with low- vs. high-frequency, and to real words that were either congruent or incongruent to the picture context. Results showed less negative N1-P2 responses for illegal sequences and low-frequency pseudowords (with differences in topography), but not high-frequency ones. Low-frequency pseudowords also showed an increased P3 component. However, just like illegal sequences, neither low- nor high-frequency pseudowords differed from congruent words in the N400. Thus, phonotactic frequency had an impact before, but not during lexical-semantic processing. Our results also suggest that phonological grammar, phonotactic frequency and lexicality may follow each other in this order during word processing.
SiNiSan Ameliorates the Depression-Like Behavior of Rats That Experienced Maternal Separation Through 5-HT1A Receptor/CREB/BDNF Pathway

Background: Early adverse life stress is an important dangerous factor in the development of psychiatric disorders, particularly depression. Available clinical antidepressant agents, such as fluoxetine, [a selective serotonin reuptake inhibitor (SSRI)], are unsatisfactory because of their side effects. SiNiSan (SNS) is a classic Chinese medicine prescription regarded to disperse stagnated liver qi to relieve qi stagnation. Therefore, this study was designed to detect the effects and molecular mechanism of SNS treatment in rats subjected to maternal separation (MS). Method: Male neonatal Wistar rats were divided into six groups including control + ddH2O, MS + ddH2O, MS + fluoxetine (5 g/kg), MS + SNS -low dose (2.5 g/kg), MS + SNS -medium dose (5 g/kg), MS + SNS -high dose (10 g/kg). The volume of drugs and ddH2O in each group are according to the weight of rats every day (10 mL/kg). Each group comprised 16 pups with 8 young and 8 adult pups. Except for the control group, all MS groups were separated from their mothers for 4 h/day from 9:00 to 13:00 during postnatal days (PNDs) 1 to 21. After MS, the six groups were intragastrically administered with ddH2O, fluoxetine, and different doses of SNS until PND 28 (for young pups) and PND 56 (for adult pups). The pups were weighed every day, and depression-like behavior was assessed by sucrose preference test, open field test, and forced swimming test. Serotonin 1A (5-HT1A) receptor, phosphorylated protein kinase A (p-PKA) substrate, cAMP response element-binding protein (CREB), p-CREB and brain-derived neurotrophic factor (BDNF) in the hippocampus were examined by Western blot, and in situ 5-HT1A receptor expression was measured by IHC. Results: Young and adult MS rats exhibited depression-like behavior. However, the depression-like behavior was ameliorated by SNS in both age groups. The levels of 5-HT1A receptor, p-CREB, and BDNF in the hippocampus were reduced in young and adult MS rats. SNS treatment significantly up-regulated the expression of 5-HT1A receptor, p-CREB, and BDNF in the hippocampus of adult MS rats. However, few significant effects on the protein expression were observed in the young MS rats. Conclusion: MS in infancy could develop depression-like behavior in young and adult. SNS treatment may perform antidepressant effects on young and adult MS rats through the BDNF/PKA/CREB pathway.
The Role of Religiosity on Fashion Store Patronage Intention of Muslim Consumers in Indonesia

Religiosity covers all aspects of human life values. Consumer decision-making in Muslim product purchase needs to involve religiosity. Muslim fashion is increasingly popular and becomes a potential business for fashion entrepreneurs in Indonesia. This condition evokes a dilemma for the consumers as Muslim fashion users on whether they have to conform to the religious sharia or follow the trend. The purpose of this article is to identify the role of religiosity as a factor affecting Muslim consumers to revisit Muslim fashion stores. This research involved 243 Muslim consumers of several Muslim fashion stores. The results showed that religiosity of Muslim consumers had a direct effect on patronage intention and indirect effect on patronage intention of Muslim fashion stores through Customer Satisfaction. The research findings are directed to managerial implications for Muslim fashion entrepreneurs in relation to consumer religiosity and marketing of Indonesian Muslim fashion products.
