Distributed infinite‐horizon optimal control of continuous‐time linear systems over network

This article deals with the distributed infinite‐horizon linear‐quadratic‐Gaussian optimal control problem for continuous‐time systems over networks. In particular, the feedback controller is composed of local control stations, which receive some measurement data from the plant process and regulates a portion of the input signal. We provide a solution when the nodes have information on the structural data of the whole network but takes local actions, and also when only local information on the network are available to the nodes. The proposed solution is arbitrarily close to the optimal centralized one (in terms of cost index) when a design parameter is set sufficiently large. Numerical simulation validate the theoretical results.
Multiscalar research on family language policy and planning in China: commentary

ABSTRACT This commentary foregrounds factors and tensions involved in intergenerational language socialization in Chinese-speaking communities and homes. Of particular interest is the manner in which younger generations in homes in which other Chinese dialects (fangyans) are spoken almost invariably seem to be shifting to Mandarin, and some of the consequences of that shift for language maintenance, cultural vitality and legitimacy, and intergenerational communication. Collectively, the reported research raises concerns about the relative status of different fangyans vis-à-vis the powerful standard variety, Mandarin, which is promoted heavily through media and language policies (as is English), in conjunction with both formal and informal education at different levels. Practical considerations favor the adoption of Mandarin to facilitate communication and successful social integration within large, diverse urban centers with a growing population of migrants from other regions and dialect areas of China. A more linguistically homogeneous Chinese population theoretically confers on individuals and society certain social, educational, and economic advantages, and thus potential opportunities for upward social mobility. However, the situation also raises deep concerns regarding cultural sustainability for ethnolinguistic and regional minorities and their rich traditions and heritage, and exposes vast social disparities within and across communities.

Clinical, Functional, and Midterm Survival Analysis on Sigma Curved Plus Ultracongruent Polyethylene Insert in Primary Total Knee Arthroplasty: A Retrospective Study

Background: Posterior-stabilized (PS) total knee arthroplasty (TKA) poses problems such as the need for intercondylar notch bone resection as well as cam and post wear and patella clunk. Owing to its heightened anterior profile, an ultracongruent polyethylene insert prevents the excessive posterior translation of tibia in the case of a deficient or scarified posterior cruciate ligament (PCL). This study aimed to determine whether an ultracongruent insert provides satisfactory clinical and functional outcomes and midterm survival benefits. Methods: Based on the reviewed medical records of 200 patients, 240 primary TKA cases involving the use of Sigma Curved Plus (DePuy International, Ltd., Leeds, UK) ultracongruent insert were retrospectively enrolled in this study. Follow-up data were used to evaluate the clinical and radiological outcomes and to conduct a Kaplan-Meier survival analysis. Results: The mean follow-up duration for 224 knees was 5.8 years (range 5-6.5 years). A revision was made due to infection in two patients and due to periprosthetic fractures in two other patients. The mean knee flexion improved from 101.97° ± 9.43° (range 85°-125°) to 125.75° ± 9.58° (range 100°-140°) at the final follow-up. The mean Knee Society score improved from 43.1 ± 9.76 to 88.3 ± 3.2, and the function score improved from 44.95 ± 7.26 to 90.16 ± 3.71. None of the patients showed radiographic loosening of either insert component, but 22 (5%) patients showed radiolucent lines (<2 mm). The Kaplan-Meier analysis showed that the five-year survival of the insert with an endpoint of revision for any reason was 98.1% (confidence interval, CI, 95.7-99.6%). Conclusion: The Sigma Curved Plus insert showed a low failure rate with good clinical, functional, and midterm survival outcomes in comparison to standard outcomes reported in earlier studies. Further follow-up studies are warranted to determine whether the insert’s performance is maintained in the long term.
Spiritual leadership and organizational citizenship behavior for the environment: An intervening and interactional analysis

The present study proposes that spiritual leadership is positively associated with organizational citizenship behavior for the environment (OCBE) directly and indirectly, via environmental justice orientation. The study also proposes harmonious environmental passion as a moderator of the relationship between spiritual leadership and OCBE. The proposed relationships were tested using time-lagged survey data from 337 supervisor-employee dyads in 41 Chinese firms. We found that spiritual leadership is positively associated with OCBE, both directly and indirectly, via environmental justice orientation. Interestingly, the results revealed that the direct association of spiritual leadership with OCBE was contingent on harmonious environmental passion. Our findings offer important implications that can help managers make appropriate interventions to reduce organizations’ carbon footprint. Highlights The relationship between spiritual leadership and OCBE was examined Data were collected from 337 supervisor-employee dyads Spiritual leadership is positively related to OCBE Environmental justice orientation mediates the spiritual leadership-OCBE link Environmental harmonious passion moderates the spiritual leadership-OCBE link
A protocol for probabilistic extreme event attribution analyses

Abstract. Over the last few years, methods have been developed to answer questions on the effect of global warming on recent extreme events. Many “event attribution” studies have now been performed, a sizeable fraction even within a few weeks of the event, to increase the usefulness of the results. In doing these analyses, it has become apparent that the attribution itself is only one step of an extended process that leads from the observation of an extreme event to a successfully communicated attribution statement. In this paper we detail the protocol that was developed by the World Weather Attribution group over the course of the last 4 years and about two dozen rapid and slow attribution studies covering warm, cold, wet, dry, and stormy extremes. It starts from the choice of which events to analyse and proceeds with the event definition, observational analysis, model evaluation, multi-model multi-method attribution, hazard synthesis, vulnerability and exposure analysis and ends with the communication procedures. This article documents this protocol. It is hoped that our protocol will be useful in designing future event attribution studies and as a starting point of a protocol for an operational attribution service.
Trauma-informed practice and supervision for volunteer counsellors of online psychological support groups during the impact of COVID-19

ABSTRACT After the COVID-19 outbreak, Social Workers across Borders (SWAB) was invited to organise crisis intervention training and supervisions for volunteer counselling teams. By reviewing the supervision records this paper found that the steps of ‘Sensitisation, Education, Scanning, Choice of Opting Out, and Recovery Facilitation’ (S-E-S-C-R) are useful to structure Trauma-Informed Supervision. Analysis indicated that volunteer counsellors have gone through three different stages, namely confusion, coordination and adaptation to changing crisis situations.
Expressions in focus

It is commonly claimed that, when a constituent is the focus of an occurrence of a sentence, certain alternatives to that constituent are relevant to our understanding of the sentence. Normally these are alternatives to the denotation of the focused constituent. However, Krifka (2007) briefly discusses the notion of expression focus , where the alternatives are linguistic items. Yet an adequate account of expression focus has not been given within the literature. This is despite the fact that it holds the potential to provide analyses of several important metalinguistic phenomena, including metalinguistic negotiation, metalinguistic negation and embedded pejorative expressions. This paper provides an account of expression focus and shows the explanatory power it holds with respect to metalinguistic phenomena. EARLY ACCESS
Organic matter composition and heterotrophic bacterial activity at declining summer sea ice in the central Arctic Ocean

The Arctic Ocean is highly susceptible to climate change as evidenced by rapid warming and the drastic loss of sea ice during summer. The consequences of these environmental changes for the microbial cycling of organic matter are largely unexplored. Here, we investigated the distribution and composition of dissolved organic matter (DOM) along with heterotrophic bacterial activity in seawater and sea ice of the Eurasian Basin at the time of the record ice minimum in 2012. Bacteria in seawater were highly responsive to fresh organic matter and remineralized on average 55% of primary production in the upper mixed layer. Correlation analysis showed that the accumulation of dissolved combined carbohydrates (DCCHO) and dissolved amino acids (DAA), two major components of fresh organic matter, was related to the drawdown of nitrate. Nitrate‐depleted surface waters at stations adjacent to the Laptev Sea showed about 25% higher concentrations of DAA than stations adjacent to the Barents Sea and in the central Arctic basin. Carbohydrate concentration was the best predictor of heterotrophic bacterial activity in sea ice. In contrast, variability in sea‐ice bacterial biomass was largely driven by differences in ice thickness. This decoupling of bacterial biomass and activity may mitigate the negative effects of biomass loss due to ice melting on heterotrophic bacterial functions. Overall, our results reveal that changes in DOM production and inventories induced by sea‐ice loss have a high potential to enhance the bacterial remineralization of organic matter in seawater and sea ice of the Arctic Ocean.
pUDK-HGF Gene Therapy to Relieve CLI Rest Pain and Ulcers: A Phase II, Double-Blind, Randomized Placebo-Controlled Trial

BackgroundCritical limb ischemia (CLI) has become a global problem. Less invasive therapy is needed. Hepatocyte growth factor (HGF) is one of the most potent angiogenic protein and the plasmid encoding human hepatocyte growth factor (HGF) is considered to be the most promising gene therapy for CLI.MethodsWe conducted a randomised, double-blind, placebo-controlled trial to assess the efficacy and safety of intramuscular injection of plasmid pUDK-HGF expressing HGF. Pain-at-rest patients and ulcer patients were enrolled as two cohorts and randomized to receive intramuscular injection of placebo or pUDK-HGF. Efficacy assessments included pain scale, ulcer size, TBI, ABI, and TcPO2 over 180 day. Safety analysis was based on the occurrence of adverse events. ResultsIn the pain-at-rest cohort, the proportion of patients with complete pain relief after receiving pUDK-HGF injections was significantly higher than that of the placebo group on day 180 (p = 0.0148). More responders with >50% pain reduction were also observed in the pUDK-HGF groups than in the placebo groups (p = 0.0168). In the ulcer cohort of patients, pUDK-HGF treatment tended to be superior to the placebo in the percentage of patients with both complete ulcer healing and >50% ulcer healing. No significant differences in the incidence of adverse events or serious adverse events were observed among the groups. ConclusionIntramuscular injection of pUDK-HGF is safe and can significantly reduce pain-at-rest and possibly promotes ulcer healing in CLI patients. The mid dose pUDK-HGF (6 mg) was the most efficacious, and is an appropriate dose for phase III clinical trial.

The New Seismotectonic Atlas of Greece (v1.0) and Its Implementation

Knowledge and visualization of the present-day relationship between earthquakes, active tectonics and crustal deformation is a key to understanding geodynamic processes, and is also essential for risk mitigation and the management of geo-reservoirs for energy and waste. The study of the complexity of the Greek tectonics has been the subject of intense efforts of our working group, employing multidisciplinary methodologies that include detailed geological mapping, geophysical and seismological data processing using innovative methods and geodetic data processing, involved in surveying at various scales. The data and results from these studies are merged with existing or updated datasets to compose the new Seismotectonic Atlas of Greece. The main objective of the Atlas is to harmonize and integrate the most recent seismological, geological, tectonic, geophysical and geodetic data in an interactive, online GIS environment. To demonstrate the wealth of information available in the end product, herein, we present thematic layers of important seismotectonic and geophysical content, which facilitates the comprehensive visualization and first order insight into seismic and other risks of the Greek territories. The future prospect of the Atlas is the incorporation of tools and algorithms for joint analysis and appraisal of these datasets, so as to enable rapid seismotectonic analysis and scenario-based seismic risk assessment.
A fast homotopy algorithm for gridless sparse recovery

In this paper, we study the solving of the gridless sparse optimization problem and its application to 3D image deconvolution. Based on the recent works of [] introducing the sliding Frank–Wolfe algorithm to solve the Beurling LASSO problem, we introduce an accelerated algorithm, denoted BSFW, that preserves its convergence properties, while removing most of the costly local descents. Besides, as the solving of BLASSO still relies on a regularization parameter, we introduce a homotopy algorithm to solve the constrained BLASSO that allows to use a more practical parameter based on the image residual, e.g. its standard deviation. Both algorithms benefit from a finite termination property, i.e. they are guaranteed to find the solution in a finite number of step under mild conditions. These methods are then applied on the problem of 3D tomographic diffractive microscopy images, with the purpose of explaining the image by a small number of atoms in convolved observations. Numerical results on synthetic and real images illustrates the improvement provided by the BSFW method, the homotopy method and their combination.

Variations in northeast Asian summer precipitation driven by the Atlantic multidecadal oscillation

By analysing a 113–year (1900–2012) observational dataset, it is shown that the interdecadal fluctuation of the summer precipitation over Northeast Asia differs from that in central East Asia during the 20th century, and has experienced three interdecadal shifts in the 1920s, mid‐1960s and late 1990s. That fluctuation coincides well with the multidecadal fluctuation of the sea surface temperature in the North Atlantic, known as the Atlantic Multidecadal Oscillation (AMO). The AMO affects Northeast Asia via a circumglobal teleconnection pattern extending from the North Atlantic to North America. Corresponding with the positive phase of this teleconnection pattern, a tripolar pattern emerges in the Asian–North Pacific sector, with anomalous low pressure over Northeast Asia and high pressure over Lake Baikal and the mid‐latitude western North Pacific. These results suggest that the positive phase of the AMO favours the occurrence of cold vortex over Northeast Asia and anomalous highs over Lake Baikal and the mid‐latitude western North Pacific in summer, which enhances the East Asian summer monsoon and southward intrusion of high‐latitude cold air, and eventually increases the summer precipitation in Northeast Asia. Furthermore, initialized decadal prediction simulations using the CCSM4 model reproduce well the observed variations of the AMO and its associated atmospheric teleconnection but with slightly shifted geographic locations. The simulated anomalous Northeast Asia cold vortex and strong East Asian summer monsoon, lead to above‐normal summer precipitation over Northeast Asia. The modelling results confirm that the multidecadal variability in the North Atlantic can cause the observed interdecadal variations of Northeast Asia summer precipitation. Our results suggest that to understand and predict interdecadal climate change over Northeast Asia, it is important to consider the key role of the AMO.
