Fusion rules and shrinking rules of topological orders in five dimensions
Authors: Huang Yizhou , Zhang Zhi-Feng , Ye Peng
Published: November 2023

Abstract

As a series of work about 5D (spacetime) topological orders, here we employ the path-integral formalism of 5D topological quantum field theory (TQFT) established in Zhang and Ye, JHEP04 (2022) 138 to explore non-Abelian fusion rules, hierarchical shrinking rules and quantum dimensions of particle-like, loop-like and membrane-like topological excitations in 5D topological orders. To illustrate, we focus on a prototypical example of twisted BF theories that comprise the twisted topological terms of the BBA type. First, we classify topological excitations by establishing equivalence classes among all gauge-invariant Wilson operators. Then, we compute fusion rules from the path-integral and find that fusion rules may be non-Abelian; that is, the fusion outcome can be a direct sum of distinct excitations. We further compute shrinking rules. Especially, we discover exotic hierarchical structures hidden in shrinking processes of 5D or higher: a membrane is shrunk into particles and loops, and the loops are subsequently shrunk into a direct sum of particles. We obtain the algebraic structure of shrinking coefficients and fusion coefficients. We compute the quantum dimensions of all excitations and find that sphere-like membranes and torus-like membranes differ not only by their shapes but also by their quantum dimensions. We further study the algebraic structure that determines anomaly-free conditions on fusion coefficients and shrinking coefficients. Besides BBA, we explore general properties of all twisted terms in 5D. Together with braiding statistics reported before, the theoretical progress here paves the way toward characterizing and classifying topological orders in higher dimensions where topological excitations consist of both particles and spatially extended objects.

Purpose

To explore the epidemiological trends in acetabular fracture and report the mid-term to long-term clinical outcomes of the elderly treated with operation.

Methods

Retrospective study. Patients aged ≥ 14 years with operative treatment of the Acetabular fracture from Jan 2010 to Dec 2019 at a level-1 trauma centre were identified to analyze the epidemiological trends, and the difference in fracture patterns between young and elderly patients (≥ 60 years old) were compared. The elderly patients were followed up to evaluate their clinical outcomes and satisfaction degree (worst to best: 0 to10). The patients were divided into the 2010–2014 group and the 2015–2019 group according to the year of admission, and the clinical outcomes of the two groups were compared to verify the stability from mid-term to long-term after surgery for acetabular fracture.

Results

A total of 1024 patients (mean age 43.35 years, range 14–86 years) with acetabular fractures received operative treatment in this decade. The mean age of the acetabular fracture patients increased from 41.1 years to 47.7 years, and the proportion of elderly patients increased from 5.7% to 24.0%, with some volatility. The ratio of male to female decreased year by year, and the proportion of female patients increased with age. And the anterior fracture patterns were more common in the elderly patients compared to the young patients (P < 0.001). 118 elderly patients (82 males, 36 females; mean age 66.91 years, range 60–86 years) were followed-up (mean 77.4 months, range 35–152 months). The overall mortality rate of the elderly patients was 7.69% (9/118). The Harris hip score of those alive patients was 90.41 ± 12.91 points (excellent and good rate 84.4%). 87 patients completed the SF-12 with a normal HRQoL (PCS 50.49 ± 8.88 points; MCS 55.66 ± 8.86 points). 90.8% of the patients achieved a satisfaction score of 9 or higher. And there was no significant difference in clinical outcomes between the 2010–2014 group and the 2015–2019 group (P > 0.05).

Conclusions

In conclusion, acetabular fractures presented an obvious ageing trend in China, and the fracture patterns of the elderly patients differed from those in the young patients. Operative treatment for elderly acetabular fractures yielded satisfactory and persistent clinical outcomes from mid-term to long-term clinical.

Objectives

To investigate the advantage of T1-weighted fast fluid-attenuated inversion-recovery MRI sequence without (T1-FFLAIR) and with compressed sensing technology (T1-FFLAIR-CS), which shows improved T1-weighted contrast, over standard used T1-weighted fast field echo (T1-FFE) sequence for the assessment of fetal myelination.

Materials and methods

This retrospective single-center study included 115 consecutive fetal brain MRI examinations (63 axial and 76 coronal, mean gestational age (GA) 28.56 ± 5.23 weeks, range 19–39 weeks). Two raters, blinded to GA, qualitatively assessed a fetal myelin total score (MTS) on each T1-weighted sequence at five brain regions (medulla oblongata, pons, mesencephalon, thalamus, central region). One rater performed region-of-interest quantitative analysis (n = 61) at the same five brain regions. Pearson correlation analysis was applied for correlation of MTS and of the signal intensity ratios (relative to muscle) with GA on each T1-weighted sequence. Fetal MRI–based results were compared with myelination patterns of postmortem fetal human brains (n = 46; GA 18 to 42), processed by histological and immunohistochemical analysis.

Results

MTS positively correlated with GA on all three sequences (all r between 0.802 and 0.908). The signal intensity ratios measured at the five brain regions correlated best with GA on T1-FFLAIR (r between 0.583 and 0.785). T1-FFLAIR demonstrated significantly better correlations with GA than T1-FFE for both qualitative and quantitative analysis (all p < 0.05). Furthermore, T1-FFLAIR enabled the best visualization of myelinated brain structures when compared to histology.

Conclusion

T1-FFLAIR outperforms the standard T1-FFE sequence in the visualization of fetal brain myelination, as demonstrated by qualitative and quantitative methods.

Clinical relevance statement

T1-weighted fast fluid-attenuated inversion-recovery sequence (T1-FFLAIR) provided best visualization and quantification of myelination in utero that, in addition to the relatively short acquisition time, makes feasible its routine application in fetal MRI for the assessment of brain myelination.

Key Points

• So far, the assessment of fetal myelination in utero was limited due to the insufficient contrast.

• T1-weighted fast fluid-attenuated inversion-recovery sequence allows a qualitative and quantitative assessment of fetal brain myelination.

• T1-weighted fast fluid-attenuated inversion-recovery sequence outperforms the standard used T1-weighted sequence for visualization and quantification of myelination in utero.

Intelligent speech recognition algorithm in multimedia visual interaction via BiLSTM and attention mechanism
Authors: Feng Yican
Published: November 2023

With the rapid development of information technology in modern society, the application of multimedia integration platform is more and more extensive. Speech recognition has become an important subject in the process of multimedia visual interaction. The accuracy of speech recognition is dependent on a number of elements, two of which are the acoustic characteristics of speech and the speech recognition model. Speech data is complex and changeable. Most methods only extract a single type of feature of the signal to represent the speech signal. This single feature cannot express the hidden information. And, the excellent speech recognition model can also better learn the characteristic speech information to improve performance. This work proposes a new method for speech recognition in multimedia visual interaction. First of all, this work considers the problem that a single feature cannot fully represent complex speech information. This paper proposes three kinds of feature fusion structures to extract speech information from different angles. This extracts three different fusion features based on the low-level features and higher-level sparse representation. Secondly, this work relies on the strong learning ability of neural network and the weight distribution mechanism of attention model. In this paper, the fusion feature is combined with the bidirectional long and short memory network with attention. The extracted fusion features contain more speech information with strong discrimination. When the weight increases, it can further improve the influence of features on the predicted value and improve the performance. Finally, this paper has carried out systematic experiments on the proposed method, and the results verify the feasibility.
Grenzen der Substitution ärztlicher Leistungen durch nichtärztliches Rettungsdienstpersonal
Authors: Bollinger M. , Russo S. G.
Published: November 2023

Hintergrund

Die Regierungskommission für eine moderne und bedarfsgerechte Krankenhausversorgung hat in ihrer neunten Stellungnahme eine weitgehende Substitution des Notarztdiensts durch nichtärztliches Rettungsdienstpersonal empfohlen. Insbesondere bei hochinvasiven, potenziell lebensrettenden Maßnahmen stellt sich die Frage, inwieweit eine Substitution durch nichtärztliches Rettungsdienstpersonal möglich ist. Um dies zu evaluieren, führten wir eine systematische Literaturrecherche zur endotrachealen Intubation durch Notärzte und nichtärztliches Rettungsdienstpersonal durch und verglichen die Ergebnisse miteinander.

Methode

Wir führten eine systematische Literaturrecherche in pubmed.gov (National Center for Biotechnology Information, U.S. National Library of Medicine, Rockville Pike, Bethesda, MD, USA) zu „first pass success“, Gesamterfolgsrate und unerkannten ösophagealen Fehlintubationen von präklinischen endotrachealen Intubationen durch nichtärztliches Rettungsdienstpersonal und Notärzte durch. Suchworte waren „prehospital“ und „intubation“ und „success“. Eingeschlossen wurden prospektive und retrospektive Studien, deren Daten aus dem gleichen Rettungsdienstsystem stammten. Die Ergebnisse wurden narrativ ausgewertet.

Ergebnisse

Wir erhielten insgesamt 523 Ergebnisse, von denen 8 Studien die Einschlusskriterien erfüllten. Auch in grundsätzlich Paramedic-basierten Rettungsdienstsystemen werden Notärzte eingesetzt, wie 7 der eingeschlossenen Studien zeigen. Notarztgeführte Rettungsmittel hatten einen hohen Intubationserfolg, auch wenn die Intubation durch nichtärztliches Rettungsdienstpersonal erfolgte. Der Intubationserfolg von nicht notarztgeführten Rettungsmitteln war deutlich schlechter. Die Qualifikation des eingesetzten notärztlichen Personals hatte einen deutlichen Einfluss auf den Intubationserfolg in den untersuchten Studien.

Schlussfolgerung

Hochinvasive Maßnahmen, wie z. B. die endotracheale Intubation, benötigen eine entsprechende Expertise. Eine Substitution dieser Maßnahmen durch Notfallsanitäter ist problematisch. Es wird daher auch weiterhin eine hohe Anzahl bodengebundener Notärzte nötig sein. Anforderungen an die Qualifikation des eingesetzten notärztlichen Personals sollten erhöht werden.

Imitation learning by state-only distribution matching
Authors: Boborzi Damian , Straehle Christoph-Nikolas , Buchner Jens S. , Mikelsons Lars
Published: November 2023

Imitation Learning from observation describes policy learning in a similar way to human learning. An agent’s policy is trained by observing an expert performing a task. Although many state-only imitation learning approaches are based on adversarial imitation learning, one main drawback is that adversarial training is often unstable and lacks a reliable convergence estimator. If the true environment reward is unknown and cannot be used to select the best-performing model, this can result in bad real-world policy performance. We propose a non-adversarial learning-from-observations approach, together with an interpretable convergence and performance metric. Our training objective minimizes the Kulback-Leibler divergence (KLD) between the policy and expert state transition trajectories which can be optimized in a non-adversarial fashion. Such methods demonstrate improved robustness when learned density models guide the optimization. We further improve the sample efficiency by rewriting the KLD minimization as the Soft Actor Critic objective based on a modified reward using additional density models that estimate the environment’s forward and backward dynamics. Finally, we evaluate the effectiveness of our approach on well-known continuous control environments and show state-of-the-art performance while having a reliable performance estimator compared to several recent learning-from-observation methods.
Revitalizing Urban Places: How Prosocial Organizations Acquire Saliency in the Eyes of Resisting Stakeholders
Authors: Capo Francesca , Vaccaro Antonino , Berrone Pascual
Published: November 2023

Prosocial organizations represent key actors in the quest to promote positive change, foster social impact, and revitalize cities. Notwithstanding their importance in tackling the increasing challenges threatening our society (e.g., pollution, socio-economic inequalities), these actors may not be perceived as salient in the eyes of different stakeholders, and thus their work may be jeopardized by multiple forms of resistance. Scant attention in research has been devoted to understand how prosocial organizations may acquire saliency and navigate these forms of resistance while pursuing urban revitalization. We address this gap by engaging in a qualitative investigation of a Sicilian cultural center. We found that the prosocial organization in our study could navigate different occurrences of resistance and acquire saliency by enacting mechanisms that leveraged the engagement of supporting stakeholders and the idiosyncratic characteristics of place. Our study contributes to the literature about urban revitalization, prosocial organizations, and stakeholder theory—while also complementing research investigating the role of place in management.

To research the effect of the COVID-19 pandemic on mental health, the prevalence and characteristics of all completed suicides in the city of Frankfurt am Main were compared for a 10-month period before the pandemic (March 2019–December 2019) with one during the early pandemic (March 2020–December 2020). Medicolegal data collected in the context of the FraPPE suicide prevention project were evaluated using descriptive statistical methods. In total, there were 81 suicides during the early pandemic period, as opposed to 86 in the pre-pandemic period. Though statistically not significant, the proportion of male suicides (73%) was higher during the early pandemic period than before (63%). The age-at-death was comparable in the pre-pandemic and pandemic periods (average, 54.8 vs. 53.1 years). Between these two periods, there was no difference in respect to the three most commonly used suicide methods by men: fall from a height (26% vs. 22%), intoxication, and strangulation (each 24% vs. 19%). For women, there was, however, a shift in methods from strangulation (38%), intoxication (28%), and fall from a height (19%) to fall from a height (50%), strangulation (18%), intoxication, and collision with a rail vehicle (14% each). There was a trend towards more suicides among non-German nationals during the early pandemic (suicide rate/100,000 inhabitants: German, 14.3 vs. 11.5; non-German, 4.4 vs. 8.8). Before the pandemic, 54% of the suicides were known to have a mental illness in contrast to 44% during the early pandemic. Overall, no increase in completed suicides could be observed in Frankfurt am Main during the early pandemic.
Functional and nonfunctional parathyroid carcinoma: two case reports and literature review
Authors: Yin Zhidong , Xu Xi , Cheng Lu , Kong Weike , He Yingfei , Wang Xiaogang
Published: November 2023

Parathyroid carcinoma (PC) is a rare malignant endocrine tumor. It can be divided into functional and non-functional types according to the tumor’s ability to secrete parathyroid hormone. Herein, we present a case each of functional and nonfunctional PC. Case 1: Functional PC. The main clinical symptoms were high parathyroid hormone and hypercalcemia with bone injury and other complications. The mass was large, capsulated, and showed vascular invasion. The tumor was surgically removed, along with a part of the tracheal wall and recurrent laryngeal nerve that were invaded by the tumor. The ipsilateral and isthmus thyroid lobe and central lymph nodes were also removed. Medicines were given to lower blood calcium. The patient died 18 months after surgery because of severe pulmonary infection and tracheal stenosis. Case 2: Non-functional PC. The patient showed no obvious clinical symptoms, but physical examination revealed a thyroid nodule. Despite the small diameter, the mass still invaded the surrounding thyroid lobe, fat, and muscle tissue. Surgery was performed to remove the tumor and ipsilateral thyroid lobe and central lymph nodes. The patient survived without recurrence or metastasis. Thus, we believe that the prognosis of PC negatively correlates with the scope of surgery. Early surgery can improve patient prognosis, and physical examination is conducive to early detection of PC. Herein, we provide a description of the diagnostic workup and the treatment approach and review relevant studies. We summarize the clinicopathological characteristics of PC cases to provide evidence for early diagnosis and therapy, to improve patient prognosis.

Authors: Bai Fei , Hu Qiuxia , Yao Xiaowei , Cheng Ming , Zhao Lina , Xu Linlin
Published: November 2023

Objective: The consistency of bladder volume is very important in pelvic tumor radiotherapy, and portable bladder scanner is a promising device to measure bladder volume. The purpose of this study was to investigate whether the bladder volume of patients with pelvic tumor treated with radiotherapy can be accurately measured using the Meike Palm Bladder Scanner PBSV3.2 manufactured in China and the accuracy of its measurement under different influencing factors. Methods: A total of 165 patients with pelvic tumor undergoing radiotherapy were prospectively collected. The bladder volume was measured with PBSV3.2 before simulated localization. CT simulated localization was performed when the bladder volume was 200-400ml. The bladder volume was measured with PBSV3.2 immediately after localization and recorded. The bladder volume was then delineated on CT simulation images and recorded. To compare the consistency of CT simulation bladder volume and bladder volume measured by PBSV3.2. To investigate the accuracy of PBSV3.2 in different sex, age, treatment purpose, and bladder volume. Results: There was a significant positive correlation with bladder volume on CT and PBSV3.2 (r = 0.874; p < 0.001). The mean difference between CT measured values and PBSV3.2 was (-0.14 ± 50.17) ml. The results of the different variables showed that the overall mean of PBSV3.2 and CT measurements were statistically different in the age ≥ 65 years, bladder volumes > 400ml and ≤ 400ml groups (p = 0.028, 0.002, 0.001). There was no statistical significance between the remaining variables. The volume difference between PBSV3.2 measurement and CT was 12.87ml in male patients, which was larger than that in female patients 3.27ml. Pearson correlation analysis showed that the correlation coefficient was 0.473 for bladder volume greater than 400ml and 0.868 for bladder volume less than 400ml; the correlation coefficient of the other variables ranged from 0.802 to 0.893. Conclusion: This is the first large-sample study to evaluate the accuracy of PBSV3.2 in a pelvic tumor radiotherapy population using the convenient bladder scanner PBSV3.2 made in China. PBSV3.2 provides an acceptable indicator for monitoring bladder volume in patients with pelvic radiotherapy. It is recommended to monitor bladder volume with PBSV3.2 when the planned bladder volume is 200-400ml. For male and patients ≥ 65 years old, at least two repeat measurements are required when using a bladder scanner and the volume should be corrected by using a modified feature to improve bladder volume consistency.
Research on the mixed-mode fracture damage characteristics of shale soaked in different drilling fluids
Authors: Suo Yu , Zhao Yan-Jie , Fu Xiao-Fei , He Wen-Yuan , Pan Zhe-Jun
Published: November 2023

Drilling fluid is a vital component in drilling engineering and can be considered as the lifeblood of the drilling. It serves multiple functions such as cooling the drill bit, cleaning the wellbore, and maintaining wellbore stability. However, when the drilling fluid penetrate into the formation, it significantly reduces the mechanical properties of the rocks thus making the wellbore prone to instability. This paper focuses on the studying the fracture characteristics of shale samples with different pre-crack angles (15°, 30°, 45°) when immersion in different types of drilling fluids (water-based drilling fluid, alcohol-based drilling fluid, oil-based drilling fluid) using the SCB (Semi-circular bending) test. During the experiment, digital image correlation and acoustic emission techniques were employed to monitor and analyze the fracture characteristics of shale. The research findings showed that as the pre-crack angle increases, the fracture toughness and effective fracture toughness of Mode I fractures decrease continuously, while the fracture toughness of Mode II fractures gradually increases. The impact of drilling fluids on the fracture toughness of shale samples is in the following order: water-based drilling fluid > alcohol-based drilling fluid > oil-based drilling fluid. The length of the fracture process zone (FPZ) decreased with the increase of the pre-crack angle, and the FPZ length under different drilling fluid immersion shows varying degrees of enlargement, with the following effect: water-based drilling fluid > alcohol-based drilling fluid > oil-based drilling fluid. The horizontal strain and horizontal displacement generated before the rock sample fractures increase with the increasing angle of the pre-crack. After immersion in drilling fluid, the layering of horizontal displacement field becomes more evident, with the degree of straightness of horizontal displacement affecting it in the following order: oil-based drilling fluid > alcohol-based drilling fluid > water-based drilling fluid. As the pre-crack angle of the SCB sample gradually increases, the relative decrease in acoustic emission energy becomes more pronounced, and the decrease in b-value becomes more significant. After immersion in drilling fluid, the acoustic emission becomes more pronounced, and the b-value becomes more disorderly and decreases further. Finally, by analyzing the fracture patterns of SCB samples immersed in different drilling fluids, relevant fracture mode diagrams were established. The findings could be useful in developing strategies for optimizing drilling fluid selection and fracture stimulation design in shale formations.
Properties in Ancient Metaphysics
Authors: Marmodoro Anna
Published: November 2023

This Element provides an overview of how the ancient thinkers (Anaxagoras, Plato and Aristotle) theorised about properties; such overview puts in relief the inquiries, problems and solutions they were pursuing while engaged in dialogue with each other. It examines alternative philosophical perspectives existing in antiquity concerning the explanation of property qualification, qualitative similarity, compositeness, and oneness. It further argues that although Plato was the first to conceptualise recurring universals, he did not reify them and did not admit them in his ontology; it was Aristotle who did, and developed his metaphysics around them. Aristotle, building on Plato's work, identified the metaphysical phenomenon of the instantiation of properties and developed an account for it. Finally, this Element outlines Aristotle's 'sophisticated' account of the oneness of a substance and argues that it was not hylomorphic.
The Life Course in Old English Poetry
Authors: Soper Harriet
Published: November 2023

In the first book-length study of the whole lifespan in Old English verse, Harriet Soper reveals how poets depicted varied paths through life, including their staging of entanglements between human life courses and those of the nonhuman or more-than-human. While Old English poetry sometimes suggests that uniform patterns shape each life, paralleling patristic traditions of the ages of man, it also frequently disrupts a sense of steady linearity through the life course in striking ways, foregrounding moments of sudden upheaval over smooth continuity, contingency over predictability, and idiosyncrasy over regularity. Advancing new readings of a diverse range of Old English poems, Soper draws on an array of supporting contexts and theories to illuminate these texts, unearthing their complex and fascinating depictions of ageing through life. This title is part of the Flip it Open Programme and may also be available Open Access.

Nonhuman Subjects
Authors: Luisetti Federico
Published: November 2023

The surging wave of indigenous politics, rights of nature, and social movements acting with rocks, rivers, glaciers, and lakes has brought to light an ecology of nonlife. Its protagonists are 'earth-beings,' geobodies that question deep-seated Western notions of personhood. Mountains in the Andes, erratic boulders, a landfill in the Swiss Alps, the sacred stones of the Standing Rock Sioux Reservation, and the works of contemporary artists who have engaged with nonlife reveal the subjectivity of beings that are not sentient and alive as biological organisms.
King Alfred the Great, his Hagiographers and his Cult
Authors: Kalmar Tomás Mario
Published: November 2023

This book situates Alfred the Great in his hagiographic context. For 150 years, the fables told in the ninth century about Alfred's childhood have posed interlocking disciplinary challenges to historians committed to evicting romance from history. Blending current Hagiography Studies with historical, literary, and biblical hermeneutics can help us forgo the anti-hagiographic commitments which motivated the scholars who purified the Victorian cult of Alfred by expunging his legends and salvaging his historicity. The book focusses on the typological functions of three Alfredian fables from the 'Old English Chronicle', the 'Old English Boethius', and Asser's 'Vita Ælfredii', analyses the plot common to all three, critiques the psychological conjecture that Alfred's childhood memory was their common source, and shows that synoptically they can help us see how Alfred shaped the curve of his own life's destiny and how he engaged in the formation of his own cult to last a thousand years.
Rebuilding Cities and Citizens
Authors: Haderer Margaret
Published: November 2023

In Vienna after WWI and Berlin after WWII, the provision of mass housing not only was a response to a dire social need but also served as a key lever for building variants of socialism and liberalism. Zooming into the interplay between political ideologies and the production of space, this book shows that ideologies, understood as political beliefs that underpin everyday life, are never simply 'written' into space but that their meaning is made and re-made, negotiated and contested, and sometimes cunningly subverted in and through space. How people live was - and continues to be - a profoundly political question that involves negotiations of, and decisions on, norms and ideals of citizenship, freedom, equality, property, democracy, gender, and family life - negotiations and decisions that come with legacies that shape the present.
Biometric data's colonial imaginaries continue in Aadhaar's minimal data
Authors: Sahoo Sananda
Published: November 2023

This paper considers three moments in the treatment of data about race and identity in India. Many elements go into the development of data imaginaries as these change over time. A complete history is beyond the scope of this paper, but I develop three key episodes to explore critical but changing features of interrelations between race, identity and statistical arguments historically. One aim is to explore key features of the argument developed by two significant individuals – Thomas Nelson Annadale and P.C. Mahalanobis – as they sought to develop databases that could answer questions about race formation and, in the case of Mahalanobis, might also be used to develop statistical methods on the one hand and aid governance on the other hand. A second aim is to use this historically based but highly selective investigation to uncover key features of the ideology with which the government of India has presented Aadhaar, its vast biometric identification system powered by authentication technologies afforded by artificial intelligence. This enables me to identify different forms of racial or ethnic identity that could be – and in one or two cases actually have been – implicated in the way Aadhaar has been used in practice.

This paper describes the development process of a mobile app-based version of the World Health Organization mental health Gap Action Programme Intervention Guide, testing of the app prototypes, and its functionality in the assessment and management of people with mental health conditions in Nepal. Health workers’ perception of feasibility and acceptability of using mobile technology in mental health care was assessed during the inspiration phase (N = 43); the ideation phase involved the creation of prototypes; and prototype testing was conducted over multiple rounds with 15 healthcare providers. The app provides provisional diagnoses and treatment options based on reported symptoms. Participants found the app prototype useful in reminding them of the process of assessment and management of mental disorders. Some challenges were noted, these included a slow app prototype with multiple technical problems, including difficulty in navigating ‘yes’/‘no’ options, and there were challenges reviewing detailed symptoms of a particular disorder using a “more information” icon. The initial feasibility work suggests that if the technical issues are addressed, the e-mhGAP warrants further research to understand if it is a useful method in improving the detection of people with mental health conditions and initiation of evidence-based treatment in primary healthcare facilities.
Effectiveness of dry hydrogen peroxide in reducing air and surface bioburden in a multicenter clinical setting
Authors: Wright Don , Christie Jacqueline , Lawrence Jordan , Vaughn Kimberly L. , Walsh Timothy F.
Published: November 2023

Objective:

To determine the effectiveness of dry hydrogen peroxide (DHP) in reducing environmental bioburden in occupied areas.

Design:

Prospective environmental cohort study.

Setting:

The study was conducted in 2 tertiary-care hospitals and 1 free-standing emergency department.

Intervention:

Environmental air and surface sites were cultured before and after continuous deployment of DHP systems in targeted hospital areas.

Methods:

In total, 1,554 surface and 1,036 air samples were collected from 74 patient areas among the 3 facilities on 3 consecutive days before DHP deployment and on days 14, 30, 60, and 90 after deployment. At each sampling time, 2 air samples were collected at each facility from 1 room without DHP, along with 2 outdoor samples from each facility. The impact of negative-pressure usage on the efficacy of DHP was also evaluated, with 1 hospital continuously using negative pressure, another utilizing it only in patient isolation scenarios, and another without negative pressure.

Results:

In the 2 facilities without continuous negative pressure, exposure to DHP was associated with a significant reduction in surface bioburden, characterized as total colony-forming units (P = .019; P = .002). Significant associations between DHP exposure and reductions in airborne bacterial load at the 2 hospitals were observed (P ≤ .001; P = .041), and the free-standing emergency department experienced a reduction that did not achieve statistical significance (P = .073).

Conclusions:

Our findings confirm that DHP has the potential to reduce microbial air and surface bioburden in occupied patient rooms with standard ventilation parameters.
Feed quality of modern varieties of Festuca arundinacea and Phleum pratense as an alternative to Lolium perenne in intensively managed grassland with different defoliation schemes
Authors: Becker Talea , Kayser Manfred , Isselstein Johannes
Published: November 2023

Grassland production based on cutting-only and an increasing frequency of prolonged periods of drought due to climate change could lead to decreased productivity in Lolium perenne. In field experiments, we tested whether Festuca arundinacea and Phleum pratense could be suitable alternatives to L. perenne on intensively managed grassland on clay, peat and sandy soil. The three grasses were sown in mixture with Poa pratensis and Trifolium repens and subjected to different frequencies of defoliation representing a cutting-only system, simulated grazing system and a mixed system. We found that in systems with at least six defoliations, F. arundinacea represented an acceptable compromise between feed quality (6.4 MJ net energy/kg dry matter (DM), 19.3% crude protein, CP), persistence (mass proportion >90%), and DM yield (12.7 Mg/ha). However, for dairy production based on intensive cutting-only systems, the quality of F. arundinacea was insufficient (5.9 MJ net energy/kg DM, 15.6% CP). Mixtures with P. pratense as the main sown species did not differ significantly in production of net energy and CP from L. perenne in cutting-only systems on sandy soil. On peat land, all sown mixtures were invaded by Holcus lanatus. We found that under frequent defoliation conditions, H. lanatus-rich swards had comparatively good DM yields (9.2 Mg/ha) and a feed quality that would be sufficient for dairy cow nutrition (net energy, 6.2–6.4 MJ/kg DM; 18.8–20.4% CP). We conclude that there is potential to adapt the choice of grasses and mixtures in different production systems to meet the challenges of climate change.

Blood flukes of freshwater fish are understudied worldwide. Consequently, genetic information and data on their intramolluscan stages are scarce. In the current study, freshwater limpets of the genus Burnupia (Burnupiidae) from South Africa were examined for digeneans. Of 1645 specimens, 3.10% were infected by Sanguinicolidae larvae. Four sanguinicolids were distinguished by body size, number of penetration glands, tegumental spines’ patterns and relative sizes of the finfolds on the body and furcae. Analyses of 28S, 18S and ITS rDNA sequences showed that the morphotypes were distinct from each other and from sanguinicolids whose genetic data are available. The present study is the first genetic characterization of sanguinicolids from Africa. Phylogenetic reconstruction revealed that the present species clustered with a sanguinicolid from Poland and were sister to Sanguinicola and Pseudosanguinicola from Russia and USA, respectively. The results indicate that the current species represent an unknown genus. What is more, blood fluke sequences from East Africa (presumed to be sanguinicolids), were distant from Sanguinicolidae and showed a closer relationship with acipensericolids from the USA. Freshwater fish blood flukes seem to be more diverse than previously recorded and use species of at least 13 gastropod families as intermediate hosts.
Translanguaging in a transplanted ground

The proliferation of English as an international language has had significant ramifications for the teaching and learning of languages in various educational contexts (Yu & Liu, 2022). Within the realm of higher education, the adoption of English-medium instruction (EMI) has been a particularly contentious issue, with debates raging over its potential benefits and drawbacks (Bolton et al., 2022; Bolton, Botha & Lin, 2023). One potential approach to addressing the challenges posed by EMI is the adoption of translanguaging practices, which involve the utilization of multiple languages or language varieties in communication and learning. While the concept of translanguaging has gained increasing traction in recent years, there remains a paucity of empirical research on its implementation and impact within Sino-US educational institutions where translanguaging and EMI are facing enviable pedagogical dueling.
Pseudo-Coordinated Sitzen and Stehen in Spoken German: A Case of Emergent Progressive Aspect?
Authors: Proske Nadine
Published: November 2023

This paper investigates the aspectual potential of posture verb pseudo-coordination in spoken German. In a corpus study of sitzen ‘sit’ and stehen ‘stand’, it is shown that despite a preference for activity verbs, verbs of all aspectual classes occur in the second conjunct. The posture verb imposes its durative meaning component on the second verb, thus making a progressive interpretation of the construction possible. Apart from this emergent aspectual function, German posture verb pseudo-coordination has a subjective function (conveying the speaker’s beliefs about the subject referent’s stance), and a discourse pragmatic function (information packaging).*

The North-Eastern region (NER) of India falls under the Eastern Himalayan region and it is a bio-diversity hub. Diverse maize landraces with wide adaptability to extreme climatic and soil scenario like heavy rainfall, drought and acidic soil conditions have been grown in NER since time immemorial. However, maize diversity in NER region has drastically reduced due to introduction of high yielding varieties and hybrids. Modern maize breeding programmes are focused on high yield but other unique traits like stay green trait, prolificacy (more than one fertile ear per plant), self-fertilizing ability are also important and the local germplasm of the NER region can contribute with these unique traits. Prior to the selection of any lines in several breeding programmes, assessment of genetic diversity and population structure are basic requirements. Hence, in the present study assessment of genetic diversity and population structure study in 30 maize inbreds developed from different germplasm of NER was undertaken using SSR markers, selected for their broad distribution throughout the genome, in order to assess the extent of allelic diversity among the lines and whether any population structure could be established. In addition to assessing molecular diversity, the study aims to evaluate the potential for yield and other beneficial and unique alleles that have high potential to contribute in the genetic enhancement programme of maize.
Stress response abnormalities transgenerationally inherited via miR-23 downregulation are restored by a methyl modulator during the lactation period

Low birthweight rats due to fetal undernutrition sustain higher corticosterone levels when exposed to stress. This is due to the upregulated expression of the pituitary-specific Gas5, a long noncoding RNA (lncRNA) that acts as a glucocorticoid receptor decoy and then competitively inhibiting the binding of glucocorticoids to DNA. However, the mechanism of Gas5 lncRNA upregulation remains unclear. Therefore, using the fetal undernourished model, we identified the factors that regulated Gas5 lncRNA expression and examined their effect on subsequent generations. We found that the expression levels of miR-23 was significantly lower in low birth-weight rats compared with controls. The expression of miR-23 was significantly lower and the expression levels of Gas5 lncRNA were significantly higher in the pituitary gland of low birth-weight offspring of the F2 and F3 generations compared with controls. The methyl modulator intervention in lactating F0 maternal rats restored miR-23 and Gas5 lncRNA expressions not only in F1, F2 and F3 offspring. Moreover, the intervention reduced circulating corticosterone levels and gene expressions in the pituitary gland after restraint stress exposure. In conclusion, miR-23-mediated alterations of the stress response are inherited and restored by methyl modulator intervention during lactation.

Two low-dose dicamba exposure trials were conducted on container-grown peach trees in Fayetteville, AR. Peach trees were ‘July Prince’ scions grafted onto ‘Guardian’ rootstock, were transplanted into 19-L containers, and received experimental dicamba treatments in each year. Container trials were initiated in 2020 and repeated on new trees in 2021. In the repeated application trial, dicamba was applied at 5.6 g ae ha−1 (1/100X field rate) in five sequences: an untreated control receiving no herbicide, one treatment receiving only an initial application, and three treatments receiving an initial application plus sequential applications at the same rate occurring at 14 d, 28 d, and 14 d + 28 d after initial treatment (DAT). A separate trial assessed peach tree responses to dicamba applied at 11.2 g ae ha−1 (1/50X field rate) using a selection of nozzles with differing droplet spectrum characteristics: Turbo TeeJet® induction nozzle TTI11002, air induction turbo TwinJet® nozzle AITTJ60-11002, air induction extended-range (XR) TeeJet® nozzle AIXR11002, XR TeeJet® flat-fan nozzle XR11002, and XR TeeJet® flat-fan nozzle XR1100067. Peach tree height, tree cross-sectional area, and leaf chlorophyll content were not reduced in response to any sequence of dicamba application or nozzle selection. Repeated applications of dicamba at a 1/100X rate did not increase peach injury after 28 DAT. By 84 DAT, no effect of nozzle type on peach tree injury was discernable, and all treatments caused below 4% injury. No dicamba or dicamba metabolites were observed in leaf samples collected at 14, 69, or 85 DAT from trees treated with XR1100067 or in untreated controls. While peach tree injury was observed throughout the experiment, dicamba residues were detected consistently only in 2020 from leaf samples of trees treated with dicamba at a 1/50X rate using TTI1102, AITTJ60-11002, AIXR11002, and XR11002 nozzles.
Assessing Chemical and Mineralogical Properties of the Alpine Slab Based on Field Analogs and Ambient Noise Tomography

Recent geophysical campaigns in the Alps produce images with seismic property variations along the slab of sufficiently fine resolution to be interpreted as rock transformations. Since the reacting European lower crust is presumed responsible for the variations of velocities at the top of the Alpine slab, we sampled local analogs of the lower crustal lithologies in the field and modeled the evolution of equilibrium seismic properties during burial, along possible pressure‐temperature paths for the crustal portion of the slab. The results are then compared to the range of the S‐wave velocities obtained from the S‐wave velocity tomography model along the CIFALPS transect. The velocity increase from 25 to 45 km within the slab, in the tomographic model is best reproduced by the transformation of specific lithologies in the high‐pressure granulite facies along a collisional gradient (30°C/km). Although the crust is certainly not completely homogeneous, the best candidates for the rocks that make up the top of the Alpine dip crustal panel are a kinzigite from Monte San Petrone, a gneiss from the Insubric line, and blueschist mylonite from Canavese. While they may not represent the entirety of the crust, they are sufficient to explain the tomographic velocity of the Alpine slab. A lateral lithological contrast inherited from the Variscan orogeny is not required. Eclogitization, suggested as the first‐order transformation in convergence zones, could be a second‐order transformation in collisional wedges. These results also imply a partially re‐equilibrated thermal gradient, consistent with the Alpine thermal state data at depth.
