Enhanced soft limits in de Sitter space
Authors: Armstrong C. , Lipstein A. , Mei J. 
Published: December 2022

Abstract
In flat space, the scattering amplitudes of certain scalar effective field theories exhibit enhanced soft limits due to the presence of hidden symmetries. In this paper, we show that this phenomenon extends to wavefunction coefficients in de Sitter space. Using a representation in terms of boundary conformal generators acting on contact diagrams, we find that imposing enhanced soft limits fixes the masses and four-point couplings (including curvature corrections) in agreement with Lagrangians recently derived from hidden symmetries. Higher-point couplings can then be fixed using a bootstrap procedure which we illustrate at six points. We also discuss implications for the double copy in de Sitter space.
A closed clockwork theory: ℤ2 parity and more
Authors: Choudhury Debajyoti , Maharana Suvam 
Published: December 2022

Abstract
We develop a new class of clockwork theories with an augmented structure of the near-neighbour interactions along a one-dimensional closed chain. Such a topology leads to new and attractive features in addition to generating light states with hierarchical couplings via the usual clockwork mechanism. For one, there emerges a ℤ2 symmetry under the exchange of fields resulting in a physical spectrum consisting of states, respectively even and odd under the exchange parity with a two-fold degeneracy at each level. The lightest odd particle, being absolutely stable, could be envisaged as a potential dark matter candidate. The theory can also be obtained as a deconstruction of a five-dimensional theory embedded in a geometry generated by a linear dilaton theory on a S1/ℤ2 orbifold with three equidistant 3-branes. Analogous to the discrete picture, the ℤ2 symmetry in the bulk theory necessitates the existence of a KK spectrum of even and odd states, with doubly degenerate modes at each KK level when subject to certain boundary conditions.
Rotational Differential-Linear Cryptanalysis Revisited
Authors: Liu Yunwen , Niu Zhongfeng , Sun Siwei , Li Chao , Hu Lei 
Published: December 2022

AbstractThe differential-linear attack, combining the power of the two most effective techniques for symmetric-key cryptanalysis, was proposed by Langford and Hellman at CRYPTO 1994. From the exact formula for evaluating the bias of a differential-linear distinguisher (JoC 2017), to the differential-linear connectivity table technique for dealing with the dependencies in the switch between the differential and linear parts (EUROCRYPT 2019), and to the improvements in the context of cryptanalysis of ARX primitives (CRYPTO 2020, EUROCRYPT 2021), we have seen significant development of the differential-linear attack during the last four years. In this work, we further extend this framework by replacing the differential part of the attack by rotational-XOR differentials. Along the way, we establish the theoretical link between the rotational-XOR differential and linear approximations and derive the closed formula for the bias of rotational differential-linear distinguishers, completely generalizing the results on ordinary differential-linear distinguishers due to Blondeau, Leander, and Nyberg (JoC 2017) to the case of rotational differential-linear cryptanalysis. We then revisit the rotational cryptanalysis from the perspective of differential-linear cryptanalysis and generalize Morawiecki et al.’s technique for analyzing , which leads to a practical method for estimating the bias of a (rotational) differential-linear distinguisher in the special case where the output linear mask is a unit vector. Finally, we apply the rotational differential-linear technique to the cryptographic permutations involved in , , , and . This gives significant improvements over existing cryptanalytic results, or offers explanations for previous experimental distinguishers without a theoretical foundation. To confirm the validity of our analysis, all distinguishers with practical complexities are verified experimentally. Moreover, we discuss the possibility of applying the rotational differential-linear technique to S-box-based designs or keyed primitives, and propose some open problems for future research.

AbstractOnline hemodiafiltration (OHDF) for renal replacement therapy has two modes: pre- (pre-OHDF) and post-dilution OHDF (post-OHDF). To elucidate the precise differences between the two modes, a clinical study was performed using the same polysulfone hemodiafilters in the same patients. Eight patients were treated with ABH™-22PA for 6 weeks: 3 weeks of pre-OHDF (with substitution volumes of 24, 36, and 48 L) and 3 weeks of post-OHDF (6, 8, and 10 L). The reduction ratios of urea, uric acid (UA), creatinine (CRE), inorganic phosphorus (iP), beta-2-microglobulin (β2-MG), and alpha-1-microglobulin (α1-MG) were evaluated. The removal amounts of β2-MG, α1-MG, and albumin were also evaluated by analyzing the spent dialysis fluids. The types and numbers of adverse events (AEs) and device malfunctions were recorded. The reduction ratios of urea, UA, CRE, iP, and β2-MG were comparable among all conditions, while that of α1-MG tended to be slightly higher in post-OHDF than in pre-OHDF. The removal amounts of α1-MG and albumin in pre-OHDF and post-OHDF were significantly greater with the maximum substitution volume than with the minimum volume. However, the selective removal indices, which were obtained by dividing the amount of α1-MG removed by the albumin level, tended to be slightly higher in pre- than in post-OHDF. No device-related AEs or device malfunctions occurred in either mode. No significant differences in inflammatory responses, evaluated by high-sensitivity C-reactive protein and interleukin-6, were observed. This study provides removal performance and safety data regarding the application of ABH-22PA for pre- and post-OHDF.

Abstract

Background
The efficacy of mobile stroke units (MSUs) in improving acute ischemic stroke (AIS) care in developing countries is unknown. We compared performance measures and stroke outcomes in AIS patients between MSU and usual care: emergency medical services (EMS) and walk-in.

Methods
We enrolled patients > 18 years of age with an AIS within 4.5 h after onset. Demographic data, types, and time of reperfusion therapies and clinical outcomes were recorded. A favorable outcome was defined as a modified Rankin Scale (mRS) 0–2 at 3 months.

Results
A total of 978 AIS patients (MSU = 243, EMS = 214, walk-in = 521) were enrolled between June 1, 2018, and April 30, 2021. The mean age (± SD) was 66 (± 14) years, and 510 (52.1%) were male. AIS time metrics were the shortest in the MSU with a mean (± SD) door to needle (DN) time of 20 (± 7), 29 (± 13), and 35 (± 16) min (p < 0.001) and door to puncture (DP) time of 73 ± 19, 86 ± 33, and 101 ± 42 min (p < 0.001) in MSU, EMS, and walk-in, respectively. Participants in the MSU (56.8%) received higher rate of reperfusion therapie(s) when compared to the EMS (51.4%) and walk-in (31.5%) (p < 0.001). After adjustment for any potential confounders and using the EMS as a reference, the MSU has the highest likelihood of achieving a favorable outcome (adjusted OR 2.15; 95% CI 1.39–3.32).

Conclusions
In underserved populations, MSUs significantly reduced DN time, increased the likelihood of receiving reperfusion treatment, and achieved independency at 3 months when compared to usual care.
Conceptual replication of an evidence-based peer learning programme to enhance career preparation — a cluster randomized controlled trial (RCT)
Authors: Nykänen Mikko , Törnroos Kaisa , Vuori Jukka 
Published: December 2022

Abstract Previous randomized-controlled trials have shown that a peer learning group intervention for career preparation can have positive effects on adolescent career management and the transition to post-comprehensive education in secondary schools. However, this earlier evidence of efficacy has been found by intervention studies that have implemented the method intensively. Earlier studies suggest that tailoring implementation strategies to fit organizational processes may offer opportunities to improve the sustainability and scalability of evidence-based practices. In this study, the implementation of the career preparation intervention was integrated into the school curriculum as a part of regular career counselling, lengthening the delivery timeframe of the intervention programme and using the schools’ own guidance counsellors as intervention providers. We conducted a conceptual replication study to investigate how effectively the adapted intervention programme enhanced perceived career preparation skills by carrying out a new cluster randomized-controlled trial among 1068 pupils. Linear mixed models showed that the effect of peer learning sessions on career choice preparedness was positive in comparison to that in the control group. The result suggests that the adapted intervention programme preserved its identifiable positive effects, although dismissing intensive delivery features somewhat reduced the effect size. These study results have implications for school-based career counselling interventions as schools seek to identify evidence-based methods that are cost-efficient and may be integrated into regular school routines.

Published: December 2022

AbstractCoastal dunes are extremely fragile and threatened ecotones, which play a key environmental role in terms of functional connection between terrestrial and marine ecosystems. To counteract the hydrogeological vulnerability in coastal risk areas, reliance can be made on soil bioengineering techniques, consisting of planting native species in combination with natural inert materials. These interventions involve the use of typical Mediterranean plant species, which are fundamental for increasing soil surface protection as well as for their ecologic function in coastal dune consolidation. Monitoring studies on plant growth parameters are useful to assess the suitability of the different species to be used in soil bioengineering works. Hence, this study aimed to (i) identify some Mediterranean herbaceous and shrubby plant species to be used in coastal interventions, (ii) evaluate different plant propagation methods and short-term growth parameters, and (iii) provide useful insights into field management strategies before and after transplanting.Juniperus phoenicea L., Juniperus macrocarpa Sm., Pistacia lentiscus L., Tamarix africana Poir. and Tamarix gallica L. were the selected shrubs species while Ammophila arenaria (L.) Link, Sporobolus pungens (Schreb.) Kunth., Agropyron junceum (L.) P. Beauv., Eryngium maritimum L., Calystegia soldanella (L.) R. Br., and Pancratium maritimum L. were the selected herbaceous species. As to shrubs, seeds and cuttings proved the best propagation methods with an efficiency of up to 90%. Agamic propagation methods, on the other hand, were the most efficient (80–90%) for the herbaceous species. After transplantation, all the species showed an adaptation period to the new climatic and edaphic conditions. In particular, Pistacia lentiscus L. was found withered with the presence of some radical shoots.

Published: December 2022

AbstractWear and fracture of steel dies employed in hot forging were evaluated through metallographic study with the aim of qualifying a Finite Element Simulation of the productive process. Apart from providing useful insights into the causes of die damaging, the simulation was exploited in a Design of Experiments to prevent fracture and to counter different mechanisms of wear. The objective is the optimization of die life acting only on process parameters that are directly adjustable in the actual industrial process. In the examination of stress distribution on the dies and the estimation of die wear, the complete forging cycle has been taken into consideration. Despite the considerable variability of the process, the study demonstrates that it is possible to prevent fracture insurgence and to increase the life expectancy of the die by a careful tuning of standard process parameters. Possible stakeholders of the study are not only process designers but also production managers, as most process parameters are modifiable during production.
Comparison of survival outcomes between axillary conservation and axillary lymph node dissections in N1 early breast cancer: a propensity-matched SEER analysis
Authors: Wu Nisha , Su Xiaohan , Tan Qiao , Luo Jing , Yuan Yewei , Hou Lingmi , Li Junyan 
Published: December 2022

Abstract
Background
Sentinel lymph node dissection (SLND) is an alternative to axillary lymph node dissection (ALND) for breast cancer surgery. But the criteria of SLND only for patients with limited disease in the sentinel node is disputed.

Methods
From the Surveillance, Epidemiology, and End Results (SEER) database, 2000–2015, we identified 97,296 early breast cancer females with 1–3 axillary lymph nodes macro-metastasis. Of them, 1–5 (axillary conservation group), 6–9, and ≥ 10 (ALND group) axillary lymph nodes were dissected in 28,639, 16,838, and 51,819 patients, respectively. According to the criteria of the ACOSOG Z0011 trial, two historical cohort studies of patients who underwent lumpectomy or mastectomy were conducted and the survival outcomes between ALND and axillary conservation were compared.

Results
Overall, dissection of 6–9 regional lymph nodes resulted in the worst prognosis. After propensity-matched analysis, it was found that patients in the axillary conservation group had worse survival than the ALND group in overall survival. No significant difference in prognosis between the group undergoing lumpectomy was found both in OS and BCSS. Subgroup analysis revealed that Grade 3, T2, two lymph nodes positive, or Her2 positive were the main causes of worse survival in the axillary conservation group.

Conclusion
Not all patients with N1 early breast cancer suit axillary conservation. Axillary conservation was sufficient in patients who were treated with lumpectomy. ALND cannot be omitted in patients who were ineligible for the Z0011 and undergoing mastectomy with the following characteristics: T2, Grade 3, two positive lymph nodes, and Her2 positive, which may be better complemented to the Z0011 trial. Hence, under different surgical methods, the clinical precision treatment of ALND or axillary preservation is essential.

AbstractWe report about the Early Miocene Tagay fauna of Olkhon Island, the largest island of the Baikal Lake. The Tagay fauna is of high scientific importance because of the diversity of fishes, amphibians, lizards, snakes, turtles, manifold birds and mammals. The lithology, geochemistry and the fossil record along the Tagay-1 section allow reconstruction of various palaeoenvironments, i.e. open water, shallow lakes with adjacent wetlands, riverine woodlands, and also forested and dry habitats. The fossil record, lithology and geochemical sediment-analyses suggest a temperate palaeoclimate with short humid and dry periods. The small mammal record and the magnetic polarity pattern of the upper part of section Tagay-1 correlate with the subchrons C5Cn.2r – C5Cn.1r of Chron C5C and the late Burdigalian Stage of the Geologic Time Scale (GTS2000). The corresponding age range of the Tagay fauna is ~16.5 to ~16.3 Ma.
Are hologram-like pyramid projections of an educational value? Results of a project in primary school settings
Authors: Fokides Emmanuel , Bampoukli Ioanna-Asimina 
Published: December 2022

AbstractHolograms are an emerging technology that can potentially be exploited in education. Moreover, hologram-like pyramid projections offer an attractive solution, as the cost of the device is insignificant. Yet, research on their educational uses is limited. In order to examine the impact of hologram-like pyramid projections on learning, compared to that of conventional videos, a project was implemented. The target group was one hundred and thirty-six students aged ten to twelve. The results demonstrated that there were no significant differences between the two media in terms of knowledge acquisition. On the other hand, the students in the pseudo-holograms group had more fun, were more motivated to learn, and felt that their learning was facilitated. While the above suggests that hologram-like pyramid projections offer positive learning experiences, more studies are needed in order to find ways to fully exploit their educational potential.
Designing and Implementing TeleBehavioral Health Training to Support Rapid and Enduring Transition to Virtual Care in the COVID Era
Authors: Felker Bradford L. , Towle Cara B. , Wick Ingrid K. , McKee Melody 
Published: December 2022

AbstractAs telebehavioral health continues to advance and become part of routine care, there is a need to develop effective training methods. While a consensus on how to best train telebehavioral health has not yet been achieved, this commentary will describe how evidence-based implementation strategies were used to develop a framework to create and implement a telebehavioral health training program that is relevant and enduring for a given audience. Evidence-based implementation strategies included the PARiHS criteria which were used to organize the project. Re-AIM criteria was used to organize chosen outcome measures. Important partnerships were formed to help support infrastructure as well as regional and national reach. A series of Plan-Do-Study-Act loops were used to inform progressive training series. Since April 2020, the Behavioral Health Institute has developed and offered 6 unique telebehavioral health training series, employing both webinar and online formats, and addressing core components as well as more advanced concepts. These series have provided over 19,100 accredited continuing education hours of training through June 2022, to almost 3000 unique learners via webinar and nearly 6800 unique online learners, across 45 states. Evaluations rated these trainings as high quality, relevant, and that material would likely be implemented. Feedback from attendees was considered vital in series planning. This commentary discusses how evidence-based implementation strategies can be used to create a framework upon which to base a training program for health care providers. An example is given on how this framework was used to create successful, relevant, and enduring telebehavioral health training.
Without a Debate on Sufficiency, a Circular Plastics Economy will Remain an Illusion
Authors: Mederake Linda 
Published: December 2022

AbstractTo tackle the “plastic crisis”, the concept of circular economy has attracted considerable attention over the past years, both by practitioners and scholars alike. Against this background, this article reflects from a political scientist’s point of view on key issues currently under discussion regarding the implementation of a circular plastics economy. To do so, the article covers issues raised at the 2021 edition of the Tutzing Symposion, an annual event organized by DECHEMA, the German Society for Chemical Engineering and Biotechnology. These issues include renewable feedstock, life cycle assessments, chemical recycling, appropriate regulatory frameworks, and the allocation of responsibilities to curb plastic pollution. In addition, the article draws on mainly social scientists’ research to point out limitations of the most common understanding of the circular economy concept which describes the circular economy as a holistic approach that enables eco-economic decoupling and thus prevents ecological collapse while still allowing for economic growth. As a result, the article calls for a paradigm shift that challenges this popular, technocratic vision of the circular economy and puts forward sufficiency, i.e., an absolute reduction in production and consumption, as a prerequisite for the realization of a truly circular plastics economy.
The disconnect between the goals of trustworthy AI for law enforcement and the EU research agenda

Published: December 2022

AbstractIn this paper, we investigate whether AI deployment for law enforcement will enable or impede the exercise of citizens' fundamental rights by juxtaposing the promises and policy goals with the crude reality of practices, funded projects, and practicalities of law enforcement. To this end, we map the projects funded by H2020 in AI for law enforcement and juxtapose them to the goals and aims of the EU in terms of Trustworthy AI and fundamental rights. We then bring forward existing research stressing that AI implementation in sensitive domains such as defense and law enforcement does not come without drawbacks, especially regarding discrimination, surveillance, data protection, and human dignity. We thoroughly analyze and assess human-centric and socially-driven lens risks and threats of using AI factors from an ethical, legal, and societal perspective (ELSA), including organizational and gender worries.
