Joint energy and flexiramp market equilibrium model for regional‐integrated electricity‐heat systems considering flexibility exploitation of district heating networks
Authors: Wang Xuechun , Chen Hongkun , Chen Lei , Wu Jun , Ding Tong 
Published: December 2021

AbstractThe increasing penetration of renewable energy resources into regional‐integrated energy systems (RIES) holds higher standards on operational flexibility. To alleviate the negative effects of insufficient operational flexibility, this paper proposes a joint market equilibrium model to obtain flexible resources in microgrids (MGs) and district heating networks (DHNs) through economic incentives. Based on the incorporation of the flexiramp (FRP) into the energy markets, a joint market mechanism is first established. Through multi‐energy synergy, the FRP provisions on the supply and demand sides in MGs are then introduced. Considering the flexibility exploitation of DHNs, a collaborative FRP supply method is developed to formulate the optimal bidding strategy for MGs. Moreover, a hierarchical model is designed to achieve joint market equilibrium, where MGs strategically bid in the external layer and the RIES operator optimally clears the market in the internal layer. The combined utilization of the Q‐learning algorithm and path‐tracking interior point method is applied to solve the hierarchical model efficiently. The performance of the proposed approach is verified by case studies. The results demonstrate the efficacy of the proposed approach for operational flexibility improvement through minimizing renewable energy curtailment, the overall cost, and the average energy prices.

AbstractCarbon‐based materials have been widely applied in electrochemical field because of good conductivity and low cost. However, the electrochemical performances have been hindered by few active sites in themselves, heteroatom doping is a general method to solve the problem. Herein, boron (B) is doped into the carbon nitride (CN) derived from glucose and melamine by a facile way, and cobalt (Co) is introduced in the B‐doped carbon nitride (BNC) to form Co@BNC nanocomposites. Among the different contents of Co in Co@BNC series, 12%Co@BNC shows the best oxygen reduction reaction properties with half‐wave potential of 0.78 V, good stability and methanol tolerance in alkaline solution. Besides, 12%Co@BNC also shows oxygen evolution reaction voltage of 1.67 V, and good bifunctional electrocatalysis behaviors with ∆E of 0.89 V. This bifunctional electrocatalyst can be applied in zinc‐air batteries for transportation field.
Allianzverträge – Ohne Rechtsstreit durch die Krise
Authors: Deutschmann Daniel 
Published: December 2021

AbstractClaim‐ and anti‐claim‐management is becoming increasingly important on construction sites. More and more (human) resources from contractor and owner are being invested in projects for this purpose. This is clearly counterproductive for the success of the project, since claim and anti‐claim‐management do not create any added value in the project and the actual target of a construction project is pushed into the background. In this article, the differences between plannable and dynamic‐complex systems are used to show, where classic construction contract models reach their limits and which projects are better implemented with alternative contracts. Based on the Alliance Contract for the successfully completed project „Triebwasserweg Maria Stein”, it is shown why Alliance Contracts are more suitable than classic contract models for dynamic‐complex (risky) large‐scale projects, such as large tunnel projects in difficult geology. By choosing the right contract model for the project, the best project results can be achieved, and legal disputes can be avoided even in crisis situations.

Published: December 2021

AbstractThe Stockholm bypass (E4 Förbifart Stockholm) is being built by the Swedish Transport Administration (Trafikverket) – the office responsible for transport infrastructure in Sweden. The project aims to improve connections between the regional town centres and reduce congestion on the main urban roads. The route, which runs mainly underground, employs numerous contractors and has a planned construction period of 14 years, preceded by a 10‐year planning phase. This article looks at three projects: the FSE 61 Akalla Interchange, the FSE 309 Lovön Interchange and in particular, the FSE 613 Akalla Tunnel. The Akalla Tunnel is driven as a conventional full‐face excavation with pre‐grouting and supported with rock bolts and steel‐fibre‐reinforced shotcrete. The tunnel excavation is followed by the interior work comprising precast concrete walls, a suspended membrane reinforced with shotcrete, ceiling foundations and the carriageway structure.
Tunnel Swinemünde – Hydroschildeinsatz unter der Ostsee
Authors: Göbl Arthur 
Published: December 2021

AbstractThis paper discusses the concept and the practical experiences of excavating an under‐river crossing with a slurry shield (D = 13.45 m) to construct a single‐tube road tunnel. Unstable sand and gravel as well as harder chalk zones in the invert area combined with high groundwater pressure require the tunnel face to be actively supported at all times. Over long stretches the overburden to the river bed is only around 0.5 D, which means that a delicate balance has to be struck between achieving the minimum support pressure required to stabilise the tunnel face while at the same time preventing blow‐out. An innovative segment sealing system with integrated expanding insert combined with a push‐fit dowel system achieves a high degree of protection from moisture and voids. The evacuation and rescue concept for the single‐tube road tunnel is based on a refuge running under the carriageway. This evacuation channel is accessed via staircases in recesses at the side. Ground freezing is used to stabilise the sand during excavation of the recesses at around 4 bar water pressure.

Published: December 2021

AbstractWorking Group 169.02 has been working on the revision of Austrian standard ÖNorm B 2203‐2 ”Underground Works – Works Contract – Part 2: Continuous Driving“ since mid‐2016. For tunnelling classes, the common goal was to develop a classification methodology with balanced risk allocation which would improve calculability and make billing more transparent. A further focus was to minimise the potential for disputes during project management. To achieve these goals, tunnelling classes are to be classified on the basis of machine operating data.

Published: December 2021

AbstractMicroglia proliferate during brain development and brain lesions, but how this is coordinated at the transcriptional level is not well understood. Here, we investigated fundamental aspects of the transcriptional process associated with proliferation of mouse microglia during postnatal development and in adults in a model of induced microglial depletion‐repopulation. While each proliferative subset displayed globally a distinct signature of gene expression, they also co‐expressed a subgroup of 1370 genes at higher levels than quiescent microglia. Expression of these may be coordinated by one of two mechanisms of regulation with distinct properties. A first mechanism augments expression of genes already expressed in quiescent microglia and is subject to regulation by Klf/Sp, Nfy, and Ets transcription factors. Alternatively, a second mechanism enables de novo transcription of cell cycle genes and requires additional regulatory input from Lin54 and E2f transcription factors. Of note, transcriptional upregulation of E2f1 and E2f2 family members may represent a critical regulatory checkpoint to enable microglia to achieve efficient cell cycling. Furthermore, analysis of the activity profile of the repertoire of promoter‐distal genomic regulatory elements suggests a relatively restricted role for these elements in coordinating cell cycle gene expression in microglia. Overall, proliferating microglia integrates regulation of cell cycle gene expression with their broader, context‐dependent, transcriptional landscape.
Non‐stimulated regions in early visual cortex encode the contents of conscious visual perception

Published: December 2021

AbstractPredictions shape our perception. The theory of predictive processing poses that our brains make sense of incoming sensory input by generating predictions, which are sent back from higher to lower levels of the processing hierarchy. These predictions are based on our internal model of the world and enable inferences about the hidden causes of the sensory input data. It has been proposed that conscious perception corresponds to the currently most probable internal model of the world. Accordingly, predictions influencing conscious perception should be fed back from higher to lower levels of the processing hierarchy. Here, we used functional magnetic resonance imaging and multivoxel pattern analysis to show that non‐stimulated regions of early visual areas contain information about the conscious perception of an ambiguous visual stimulus. These results indicate that early sensory cortices in the human brain receive predictive feedback signals that reflect the current contents of conscious perception.

AbstractConvergent clinical and neuroimaging evidence suggests that higher vestibular function is subserved by a distributed network including visuospatial, cognitive–affective, proprioceptive, and integrative brain regions. Clinical vestibular syndromes may perturb this network, resulting in deficits across a variety of functional domains. Here, we leverage structural and functional neuroimaging to characterize this extended network in healthy control participants and patients with post‐concussive vestibular dysfunction (PCVD). Then, 27 healthy control subjects (15 females) and 18 patients with subacute PCVD (12 female) were selected for participation. Eighty‐two regions of interest (network nodes) were identified based on previous publications, group‐wise differences in BOLD signal amplitude and connectivity, and multivariate pattern analysis on affective tests. Group‐specific “core” networks, as well as a “consensus” network comprised of connections common to all participants, were then generated based on probabilistic tractography and functional connectivity between the 82 nodes and subjected to analyses of node centrality and community structure. Whereas the consensus network was comprised of affective, integrative, and vestibular nodes, PCVD participants exhibited diminished integration and centrality among vestibular and affective nodes and increased centrality of visual, supplementary motor, and frontal and cingulate eye field nodes. Clinical outcomes, derived from dynamic posturography, were associated with approximately 62% of all connections but best predicted by amygdalar, prefrontal, and cingulate connectivity. No group‐wise differences in diffusion metrics or tractography were noted. These findings indicate that cognitive, affective, and proprioceptive substrates contribute to vestibular processing and performance and highlight the need to consider these domains during clinical diagnosis and treatment planning.
The best choice of induction chemotherapy for patients with locally advanced nasopharyngeal carcinoma: Bayesian network meta‐analysis

Published: December 2021

AbstractThe determination of the optimal induction chemotherapy (IC) regimen for patients with locally advanced nasopharyngeal carcinoma (NPC) remains controversial. Eligible trials included in this Bayesian network meta‐analysis were judged by synthetically evaluating survival and safety outcomes. The analysis revealed that the combined IC regimen of gemcitabine plus cisplatin (GP) gained not only the most favorable overall survival (OS) benefit but also longer distant metastasis‐free survival and manageable adverse events (AEs). Additionally, combination IC regimen of mitomycin, epirubicin, cisplatin, fluorouracil, and leucovorin had insufficient significant efficacy on complete response. Docetaxel combined with cisplatin and fluorouracil induction regimen provided the first exact probability of efficacy in term of local recurrence‐free survival, ranking second in OS, but accompanied by the highest rates of grade 3 or above AEs. GP regimen appears to be currently the best choice of IC regimen for combined benefit of patients with locally advanced NPC.
Does the augmentation of monetary and non‐monetary factors prerequisite for the improvement of health outcomes? Evidence from the Indian states
Authors: Das Tiken , Das Diganta 
Published: December 2021

AbstractThe present study was conducted in Indian states to examine the effect of monetary and non‐monetary factors on Infant Mortality Rate (IMR) and Life Expectancy at Birth (LEB) by using the panel regression model. In addition, an attempt was also made to analysis the unequal pattern of health infrastructure and services across states over time with the help of a composite index on health infrastructure and services. It was found that the index value of the best performing state Chhattisgarh is more than fourth six times that of the worst performing state. The study also showed that, despite the higher level of average per capita public health expenditure and moderately better health infrastructure, the COVID 19 induced death rate was high in Punjab, Sikkim, Delhi and Goa. The panel regression results revealed that, an average increase of 1% in the monetary factor, public health expenditure to Gross State Domestic Product ratio (PHEGSDPR), would decrease the average of IMR by about 10%. Moreover, the elasticity of IMR with respect to non‐monetary factor, health infrastructure and services per 0.1 million population (HISPLP), was negative and significant. Likewise, the explanatory variables, HISPLP and PHEGSDPR have a positive and significant effect on the LEB.

Published: December 2021

AbstractObjectiveThe objective of the present research was to study the association between precipitous labor (less than 3 h) and the onset of transient tachypnea in singleton fetuses in cephalic presentation with term vaginal deliveries.MethodsThis cohort study included women delivered from 2013 through 2017 in our French tertiary university hospital maternity unit. Inclusion criteria were vaginal delivery of liveborn singleton fetus in cephalic presentation and at term. We compared women with precipitous labor and those with longer labor. The principal endpoint was the rate of transient tachypnea of the newborn (TTN). We investigated risk factors for TTN besides duration of labor.ResultsComparison of 2644 women with precipitous labor and 7571 with longer labor showed a lower TTN rate in the precipitous labor group (1.6 vs 2.7%; P = 0.003). The association was no longer significant after adjustment for the risk factors identified in the univariate analysis (adjusted OR 0.99, 95% CI 0.64–1.54). Risk factors identified for TTN were non‐clear amniotic fluid, shoulder dystocia, umbilical cord encirclement, birth weight less than 2500 g, use of cervical ripening and operative vaginal delivery.ConclusionPrecipitous labor, lasting less than 3 h, is not associated with a higher risk of transient tachypnea in term newborns after vaginal delivery.
Wellbeing among Black American adults living in low‐resourced communities
Authors: Alagaraja Meera , Hooper Lisa M. 
Published: December 2021

AbstractVery little is known about how Black Americans living in low‐resourced communities define and maintain wellbeing. Utilizing a culturally tailored research design, we explored the phenomenon of wellbeing as it resonated with the lived experiences of our informants (N = 35). Using a thematic analysis, we found that existing conceptualizations and theorizing of wellbeing did not consistently emerge from our data. First, we noted paradoxical tensions between descriptions of wellbeing as indicated by the participants (e.g., being alive and having a pain‐free life) and the Western, Eurocentric views evidenced in the wellbeing literature. Second, participants identified intergenerational family ties and community networks as ways that foster wellbeing. These findings suggest that we can no longer delimit and apply existing views in theorizing and measuring wellbeing. Our findings elucidated the mindsets, relationships, activities, and practices that define and foster wellbeing among Black Americans living in low‐resourced communities.

AbstractAimsWe sought to identify person‐ and program‐level factors distinguishing permanent supportive housing (PSH) residents with higher versus lower social integration; and higher versus lower instrumental functioning.MethodsAmong 60 PSH residents at Los Angeles' VA, surveys and medical records captured person‐level factors. Using a median split, we dichotomized participants with higher versus lower social integration; and higher versus lower instrumental functioning. Recursive partitioning (RP) identified variables that best‐differentiated these subgroups. Interviews with 26 participants captured their perceptions on social integration and instrumental functioning.ResultsUsing RP, health‐related quality of life, psychiatric symptoms and case management frequency best‐differentiated the social integration subgroups. Few perceived that PSH affected social integration. RP did not yield a stable model to differentiate the instrumental functioning subgroups; participants perceived that PSH addressed most functional deficits.ConclusionsServices that enhance social integration may benefit PSH residents with poor health; existing services may adequately address instrumental functioning.

AbstractThis study investigated the relations of emerging adults' personal (civic competence and interdependent self‐construal) and community‐based (sense of community and civic engagement) resources as predictors of appraisal of COVID‐19 Public Health Emergency Management (PHEM) and attitudes toward preventing contagion in Italy. Participants were 2873 Italian emerging adults (71% females) aged 19–30 years (M = 22.67, SD = 2.82). Structural equation modeling revealed both direct and indirect positive associations among study variables. Civic competence and interdependent self‐construal were related to sense of community and civic engagement behavior which, in turn, predicted appraisal of PHEM. Appraisal of PHEM in turn predicted attitudes toward preventing contagion. Overall, findings highlight the importance of examining the alignment between personal and collective interests to understand emerging adults' evaluative and attitudinal experiences during a period of crisis, such as that created by COVID‐19.

AbstractBackgroundCompleting Patient‐Generated Subjective Global Assessment (PG‐SGA) questionnaires is time consuming. This study aimed to develop and validate an easy‐to‐use modified PG‐SGA (mPG‐SGA) for cancer patients.MethodsSeventy professionals assessed the content validity, comprehensibility, and difficulty of the full PG‐SGA. A survey including the PG‐SGA and other questionnaires was completed by 34 071 adult hospitalized cancer patients with first cancer diagnosis or recurrent disease with any tumour comorbidities from the INSCOC study. Among them, 1558 patients were followed for 5 years after admission. Reliability and rank correlation were estimated to assess the consistency between PG‐SGA items and to select mPG‐SGA items. The external and internal validity, test–retest reliability, and predictive validity were tested for the mPG‐SGA via comparison with both the PG‐SGA and abridged PG‐SGA (abPG‐SGA).ResultsAfter deleting items that more than 50% of professionals considered difficult to evaluate (Worksheet 4) and items with an item‐total correlation <0.1, the mPG‐SGA was constructed. Nutritional status was categorized using mPG‐SGA scores as well‐nourished (0 points) or mildly (1–2 points), moderately (3–6 points), or severely malnourished (≥7 points) based on the area under curve (0.962, 0.989, and 0.985) and maximal sensitivity (0.924, 0.918, and 0.945) and specificity (1.000, 1.000, and 0.938) of the cut‐off scores. The external and internal validity and test–retest reliability were good. Significant median overall survival differences were found among nutritional status groups categorized by the mPG‐SGA: 24, 18, 14, and 10 months for well‐nourished, mildly malnourished, moderately malnourished, and severely malnourished, respectively (all Ps < 0.05). Neither the PG‐SGA nor the abridged PG‐SGA could discriminate the median overall survival differences between the well‐nourished and mildly malnourished groups.ConclusionsWe systematically developed and validated the mPG‐SGA as an easier‐to‐use nutritional assessment tool for cancer patients. The mPG‐SGA appears to have better predictive validity for survival than the PG‐SGA and abridged PG‐SGA.
