Published: March 2022

AbstractVolvocales forms a species‐rich clade with wide morphological variety and is regarded as an ideal model for tracing the evolutionary transitions in multicellularity. The phylogenetic relationships among the colonial volvocine algae and its relatives are important for investigating the origin of multicellularity in the clade Reinhardtinia. Therefore, a robust phylogenetic framework of the unicellular and colonial volvocine algae with broad taxon and gene sampling is essential for illuminating the evolution of multicellularity. Recent chloroplast phylogenomic studies have uncovered five major orders in the Chlorophyceae, but the family‐level relationships within Sphaeropleales and Volvocales remain elusive due to the uncertain positions of some incertae sedis taxa. In this study, we contributed six newly sequenced chloroplast genomes in the Volvocales and analyzed a dataset with 91 chlorophycean taxa and 58 protein‐coding genes. Conflicting phylogenetic signals were detected among chloroplast genes that resulted in discordant tree topologies among different analyses. We compared the phylogenetic trees inferred from original nucleotide, RY‐coding, codon‐degenerate, and amino acid datasets, and improved the robustness of phylogenetic inference in the Chlorophyceae by reducing base compositional bias. Our analyses indicate that the unicellular Chlamydomonas and Vitreochlamys are close to or nested within the colonial taxa, and all the incertae sedis taxa are nested within the monophyletic Sphaeropleales s.l. We propose that the colonial taxa in the Reinhardtinia are paraphyletic and multicellularity evolved once in the volvocine green algae and might be lost in Chlamydomonas and Vitreochlamys.
Software protection and software piracy
Authors: Jha Amit Kumar , Rajan Priyanka 
Published: March 2022

AbstractThis paper explores the dynamic long‐term relationship between software protection and software piracy rates across 108 countries over the period of 20 years (1994–2015), with the help of the ARDL model. The analysis employs a new way of utilising the membership duration of Trade related Intellectual Property Rights agreement and World Intellectual Property Organisation Copyright Treaty agreements of different countries in a panel framework, apart from constructing an index of copyright software protection by focusing on enforcement provisions. The paper overcomes various shortcomings of earlier literatures by thoughtful inclusion of independent variables and methodological techniques. Results show that both copyright software protection and income share a negative long‐term relationship with software piracy. Even the enforcement provisions are important in mitigating software piracy. In addition, the model finds a negative relationship between demand for intellectual property protection and software piracy rates.
Underwater calling behavior in two high‐altitude frog species
Authors: Zheng Y. , Xie F. 
Published: March 2022

AbstractUnderwater calls of frogs are poorly documented, probably because they are usually weak and difficult to detect out of water because the impedance contrast at the water–air interface limits sound transmission. The tympanic middle ear and vocal sacs, which may not be essential for underwater acoustic communication, are often reduced in high‐elevation anurans. In addition to the Andean Telmatobius and Sierra Nevada Rana sierrae, many other highland frog species may vocalize underwater rather than be mute as previously thought. We report evidence from the eastern Tibetan Plateau supporting this speculation. In two species of the megophryid genus Scutiger, breeding males emitted trill‐like calls in series under submerged rocks at elevations of approximately 3700 m a.s.l. Because the few high‐elevation anurans known to vocalize underwater are all highly aquatic, this strategy is possibly used because the signal receivers usually remain in water during the breeding season. The finding of underwater calling in Scutiger characterized by reduced middle ears was partly guided by co‐occurrence of loose skin and underwater vocalization in some frog species and constitutes another independent case of such co‐occurrence. We suggest that the presence/absence of loose skin folds should be routinely included in the morphological descriptions of anurans, because an increased surface/volume ratio facilitates effective cutaneous respiration that is required for metabolically costly underwater behaviors which are usually cryptic to human observers.
Interventional management and surgery of neurogenic lower urinary tract dysfunction in patients with chronic spinal cord injury: A urologist's perspective
Authors: Chen Sheng‐Fu , Kuo Hann‐Chorng 
Published: March 2022

AbstractNeurogenic lower urinary tract dysfunction (NLUTD) caused by spinal cord injury (SCI) is challenging for urologists. NLUTD not only affects the quality of life but also endangers the upper urinary tract of patients with chronic SCI. Considering that the bladder and urethral function change with time, regular follow‐up of NLUTD is necessary, and any complication should be adequately treated. The first priority of bladder management in patients with chronic SCI manifesting NLUTD should be renal function preservation, followed by the normalization of lower urinary tract function. The quality of life should also be assessed. Patients who have a high risk for impaired renal function should be more frequently identified and investigated. Conservative treatment and pharmacological therapy should be started as early as possible. Intravesical or urethral injections of botulinum toxin A is an alternative treatment for refractory NLUTD. When surgical intervention is necessary, less invasive and reversible procedures should be considered first. Improving patients' quality of life and willingness to undergo bladder management is the most important aspect of treatment.
When does portfolio compression reduce systemic risk?
Authors: Veraart Luitgard Anna Maria 
Published: March 2022

AbstractWe analyze the consequences of portfolio compression for systemic risk. Portfolio compression is a post‐trade netting mechanism that reduces gross positions while keeping net positions unchanged and it is part of the financial legislation in the United States (Dodd–Frank Act) and in Europe (European Market Infrastructure Regulation). We derive necessary structural conditions for portfolio compression to be harmful and discuss policy implications. We show that any potential harmfulness of portfolio compression arises from contagion effects. We show how portfolio compression affects systemic risk depends on the resilience of nodes taking part in compression, on the proportion of debt that they can repay, and on the recovery rates in case of default. In particular, the potential danger of portfolio compression comes from defaults of firms that conduct portfolio compression. If no defaults occur among the firms that engage in compression, then portfolio compression always reduces systemic risk.
Middle East Pre‐Existing Conditions: Regional Security after Covid‐19
Authors: Norlén Tova C. 
Published: March 2022

AbstractThis article analyzes the underlying human insecurities and changing geopolitical alliances in the Middle East during the past decade to assess the most likely short‐ and medium‐term impacts of Covid‐19 on the global security environment. In particular, it focuses on the “pre‐existing conditions” for instability in the Middle East, and the opportunity that the pandemic might have to exacerbate them. The region will likely face a growing regional‐security dilemma compounded by challenges that are now too familiar: the further entrenchment of political authoritarianism, violent sectarian conflicts, regional rivalries, and the radicalization and recruitment efforts by terrorist and extremist groups. While the pandemic has not led to a significant rise in terrorism and extremist violence, it has worsened fragility and accelerated economic decline. This has increased political instability, which, in turn, makes violence more likely. The civil wars in Syria and Yemen, continued threats from Salafi‐Jihadi extremism, massive displacement, sectarianism, and rising inequalities between the rich and the extremely poor are to blame for such fragility. Given the lack of economic resilience and the significant fragility of many Arab states, as well as the availability of advanced military technology in the region, the resulting political, socioeconomic, humanitarian, and security challenges could be devastating.
In with the New: China's Nuclear‐Energy Diplomacy in the Middle East
Authors: Sun Degang , Xu Haiyan , Tu Yichao 
Published: March 2022

AbstractNuclear energy, the new frontier of China's cooperation with the Middle East, carries both geoeconomic and geopolitical implications. The development of civil nuclear energy is conducive to the diversification of the energy structure of Middle Eastern countries, meets their increasing needs for electricity at home, and improves their seawater desalinization. Giving full play to its incremental advantage, China's diplomacy strives to expand the market share of its nuclear‐power enterprises in the Middle East, elevate its image as a rising nuclear‐energy power, and advance nuclear‐energy cooperation between China and Saudi Arabia, the UAE, Iran, Algeria, Turkey, Egypt, Jordan, and Sudan through multilateral or bilateral mechanisms. These can be classified into three categories: in‐depth cooperation, active participation, and preliminary exploration. Nuclear‐energy diplomacy aims to expand political influence through civil nuclear activity. Its aim is to enrich the toolkit of China's Middle East diplomacy and is conducive to a multipolar world in terms of civil nuclear research, development, and industries.
Disruptive innovation in psychiatry
Authors: Sarris Jerome 
Published: March 2022

AbstractDisruptive innovation is a cornerstone of various disciplines, particularly in the business world, where paradigm‐altering approaches are often lauded. As a construct, disruptive psychiatry can be considered to embody such an approach by the pursuit of innovations within the field which test boundaries and shake up the status quo. Given the importance of addressing the current mental health pandemic, and the deficit of highly effective pharmacological treatments for various conditions, innovative disruptive thinking is required. Significant promise exists via the provision of potentially more effective innovative therapeutic options, including digital interventions, psychedelic medicines, microbiome‐altering treatments, brain stimulation technology, and nanotechnology‐based delivery systems. These approaches may be further advanced by individualization of the treatments using computational technology (including quantum computing, machine learning, and artificial intelligence) and genomics.
Exchange through emoting: An emotional model of leader–member resource exchanges
Authors: Liao Zhenyu , Wu Lusi , Zhang Haoyue Jack , Song Zhaoli , Wang Yating 
Published: March 2022

AbstractDespite research suggesting that emotional interactions pervade daily resource exchanges between leaders and members, the leader–member exchange (LMX) literature has predominantly focused on the interplay between general affective experiences and the overall relationship quality. Drawing upon the affect theory of social exchange, we examine why and how discrete exchange imbalance engenders distinct emotions and shapes downstream work behaviors of the members. Results from a preregistered experimental study with 247 participants and an experience sampling study with time‐lagged reports from 79 leaders and 145 members show that a positively imbalanced exchange increases members’ subsequent leader‐directed helping via gratitude (but not via shame) and that a negatively imbalanced exchange increases members’ subsequent risk‐taking via pride (but not via anger). Moreover, the intensity of such effects hinges upon the average level of resource contributions of leader–member dyads. Our research casts light on the role of transient emotions in dynamic resource exchanges between leaders and members and enriches our knowledge of within‐dyad fluctuations of social exchanges.
Categorical phenomenalism about sexual orientation*
Authors: Whitlow T. R. , Laskowski N. G. 
Published: March 2022

AbstractWhat is sexual orientation? The contemporary consensus among philosophers is that it is a disposition. Unsurprisingly, recent debates about the metaphysics of sexual orientation are almost entirely intramural. Behavioral dispositionalists argue that sexual orientation is a disposition to behave sexually. Desire dispositionalists argue that it is a disposition to desire sexually. We argue that sexual orientation is not best understood in terms of dispositions to behave or dispositions to desire before arguing that dispositions tout court fail to illuminate sexual orientation. We then introduce and defend the idea that sexual orientation is best understood in terms of categorical phenomenal properties of sexual arousal.
Characterization of the host range and sensitivity to fungicides of Trichothecium spp. associated with fruit rot in the field and in storage

AbstractDuring 2017–2019, we observed Trichothecium spp. causing fruit rot in the field and in storage. This study was conducted to examine morphological differences of the species from different hosts, reveal the species’ potential host range, and evaluate the efficacy of five fungicides. Six strains of Trichothecium spp. isolated from nectarine, peach and walnut were selected. Although the colony morphology, mycelial growth rate and spore size differed among hosts, phylogenetic analysis based on the internal transcribed spacer and part of the 5ʹ end of the β‐tubulin gene showed that all tested strains belonged to Trichothecium roseum. For its host range, 23 kinds of fruit were examined using T. roseum strain YT‐1 as an inoculum; 10 kinds of fruit, including pear, apple, mango, Chinese chestnut, pepino melon, fig and durian, were susceptible to T. roseum, with minimum inoculation concentrations ranging from 104 to 105 spores/ml. The fungicides that most effectively inhibited the six isolates were fluazinam and fludioxonil, with EC50 values of 0.07–0.1 and 0.01–0.04 μg/ml, respectively, followed by difenoconazole (0.81–2.96 μg/ml), boscalid (5.43–13.51 μg/ml) and azoxystrobin (9.18–27.25 μg/ml). Improvement of the shelf life of nectarines held in plastic trays was explored using allyl isothiocyanate (AITC) against T. roseum YT‐1. The application of 10 μl/L AITC significantly suppressed disease symptoms. The findings provide useful information for future disease emergency management in the field and for food preservation.
A Double-Wiebe Function for Reactivity Controlled Compression Ignition Combustion Using Reformate Diesel
Authors: Yang Ruinan , Ran Zhongnan , Ristow Hadlich Rodrigo , Assanis Dimitris 
Published: March 2022

AbstractReactivity controlled compression ignition (RCCI) combustion has previously been proposed as a method to achieve high fuel conversion efficiency and reduce engine emissions. A single-fuel RCCI combustion strategy can have decreased fuel system complexity by using a reformate fuel for port fuel injection and the parent fuel (diesel) for direct injection. This paper presents a one-dimensional computational model of a compression ignition engine with single-fuel RCCI. A Wiebe function is used to predict the combustion process by representing the mass fraction burned (MFB) on a crank angle resolved basis. One single-Wiebe function (SWF) and two double-Wiebe functions(DWFs) were fitted to experimentally derive MFB data using the least-square method. The fitted results were compared with MFBs calculated from experimental data to verify the accuracy. The SWF did not fully capture the MFB curve with high fidelity while the detailed DWF captured the MFB curve within a root mean square error of 1.4%. The reduced double-Wiebe function (RDWF) also resulted in a predicted combustion profile with similar accuracy. Hence, the RDWF was used in a GT-power thermodynamic study to understand the effects of the low-temperature heat release (LTHR) fraction and combustion phasing on combustion characteristics. At optimum phasing of 5–10 crank angle degree after the top dead center, increasing the LTHR fraction from 20% to 60% resulted in the fuel conversion efficiency increasing from 39.5% to 41.1%, thus suggesting that the reformate fuel-based RCCI strategy is viable to unlock improved combustion performance.

Published: March 2022

Purpose:To determine the relative contributions of handgrip and individual finger strength for the prediction of climbing performance in a bouldering competition. A secondary aim was to examine the influence of body size, bouldering experience, and training habits.Methods:Sixty-seven boulderers (mean [SD], age = 21.1 [4.0] y; body mass = 69.5 [9.8] kg) volunteered for this study. Data collection occurred immediately before an indoor bouldering competition and involved the assessment of handgrip and individual finger maximal force production using an electronic handheld dynamometer. The bouldering competition consisted of 70 routes graded V0 to V8, with higher point values awarded for completing more difficult routes. Stepwise multiple regression analysis was used to examine the relative contributions of handgrip and individual finger strengths, body mass, height, bouldering experience, and bouldering frequency to the prediction of performance scores in the competition.Results:Ring finger pinch strength, bouldering experience, and bouldering frequency significantly (P < .05) contributed to the model (R2 = .373), whereas body mass; height; full handgrip strength, as well as index, middle, and little finger pinch strengths did not. Theβweights showed that ring finger pinch strength (β = .430) was the most significant contributor, followed by bouldering experience (β = .331) and bouldering frequency (β = .244).Conclusions:The current findings indicated that trainable factors contributed to the prediction of bouldering performance. These results suggest greater bouldering frequency and experience likely contribute to greater isolated individual finger strength, thereby optimizing preparation for the diverse handholds in competitive rock climbing.
Orbital forcing of late Early Devonian storm events on a mixed carbonate-siliciclastic shelf, Longmenshan area, Sichuan Province, China

AbstractThe Yangmaba Formation of latest Early Devonian age in the Longmenshan area of Sichuan Province, China, is a shelfal facies that consists of four types of carbonate-siliciclastic deposits: clay-rich, siliciclastic sand-rich, carbonate-dominated, and hybrid mixed. Storm deposits vary in their thickness, composition, and abundance-per-meter within these mixed carbonate-siliciclastic deposits. Meter-scale statistics of the relative storm frequency (events-per-meter) and magnitude (bed thickness) were compiled in two coeval sections through each of the hybrid facies in the lower Yangmaba Formation, which spans approximately the entire conodont Polygnathus patulus Zone of the uppermost Emsian Stage. Low-pass filtering, spectral analysis, and Acycle software interpretation of these tempestite statistics yield 3.5 main oscillations in each section, with an average wavelength of ~23 m. These long-wavelength trends are semi-coincident with interpreted long-term variations in sea level, where shallower depths allowed a greater influence by storms. Superimposed on the long-wavelength cycles are medium-wavelength cycles of 5.5–6.3 m. The estimated ~1.5 m.y. time-span of this conodont zone of the lower Yangmaba Formation and the approximate 1:4 ratios of these wavelengths indicate that frequency and intensity of major storms and the recording of tempestites in the sedimentary record were modulated by ~100- and 95-k.y.-short-eccentricity orbital-climate oscillations superimposed on a main 405-k.y.-long-eccentricity cycle. These eccentricity climate cycles governed storm intensity and regional sea level on this margin of the tropical Yangtze Platform of South China.
Apert syndrome: an informative long-term dentofacial outcome
Authors: Fowler Peter , Hallang Shirleen , Snape Leslie 
Published: March 2022

The management of patients with Apert syndrome (AS) is complex and reflects the multisystem disease as a result of premature fusion of cranial vault, cranial base and midface sutures as well as extremity anomalies characterised by syndactyly. Early cranial sutural fusion results in craniocerebral disproportion which can lead to crisis surgical intervention due to raised intracranial pressure, ophthalmic and compromised airway concerns. Childhood inventions are often determined by psychosocial concerns and adult surgical interventions are often determined by cosmetic concerns. Treatments are provided by many different specialists within multidisciplinary teams (MDT). The treatment pathway extends from birth well into adulthood and is often associated with a heavy burden of care. Due to the extensive nature of the interaction with these patients MDT members have opportunities to provide enhanced patient-centred care and support.This case report provides an overview of the current knowledge of the aetiology of AS, illustrates the pathway of surgical and non-surgical management of AS and provides a long-term review of the dentofacial treatment outcomes.By having a better understanding of the impact of AS and treatment provided, MDT members can not only provide improved clinical treatment but also offer improved patient experiences for those with craniofacial anomalies, in particular, an increased awareness of the psychosocial challenges they endure.
