Authors: Che Kai , Han Wenkai , Li Danxia , Cui Shuxia , Zhang Mingxin , Yang Xiaokun , Niu Haitao
Published: February 2021

Background: Glycolysis was a representative hallmark in the tumor microenvironment (TME), and we aimed to explore the correlations between glycolysis with immune activity and clinical traits in bladder urothelial carcinoma (BLCA).

Methods: Our study obtained glycolysis scores for each BLCA samples from TCGA by a single-sample gene set enrichment analysis (ssGSEA) algorithm, based on a glycolytic gene set. The relationship between glycolysis with prognosis, clinical characteristics, and immune function were investigated subsequently.

Results: We found that enhanced glycolysis was associated with poor prognosis and metastasis in BLCA. Moreover, glycolysis had a close correlation with immune function, and enhanced glycolysis increased immune activities. In other words, glycolysis had a positive correlation with immune activities. Immune checkpoints such as IDO1, CD274, were up-regulated in high-glycolysis group as well.

Conclusion: We speculated that in BLCA, elevated glycolysis enhanced immune function, which caused tumor cells to overexpress immune checkpoints to evade immune surveillance. Inhibition of glycolysis might be a promising assistant for immunotherapy in bladder cancer.

Authors: Tong Fei , Shen Wenchao , Song Pengtao , Song Jiafeng , Hu Yonghe , Liu Feifan , Meng Zhipeng , Liu Jing
Published: February 2021

Objective: The aim of the present study is to investigate the anti-injury and anti-inflammatory effects of dexmedetomidine (Dex) in acute liver injury induced by lipopolysaccharide (LPS) in Sprague–Dawley rats and its possible mechanism.

Methods: The acute liver injury model of male rats was established by injecting LPS into tail vein. The mean arterial pressure (MAP) of rats was recorded at 0–7 h, and lactic acid was detected at different time points. Wet/dry weight ratio (W/D) was calculated. Pathological changes of rat liver were observed by HE staining. ALT and AST levels in serum were detected. The activities of myeloperoxidase (MPO) and superoxide dismutase (SOD) in liver tissue homogenate and the levels of IL-1β and IL-18 in serum were detected by ELISA. Protein levels of Caveolin-1 (Cav-1), TLR-4 and NLRP3 in liver tissue were tested by immunohistochemistry method. The expression of Cav-1, TLR-4 and NLRP3 mRNA in liver tissue was detected by quantitative polymerase chain reaction (qPCR) to explore its related mechanism.

Results: Compared with NS group, serum lactic acid, W/D of liver tissue, MPO, SOD, IL-1β and IL-18 were significantly increased and MAP decreased significantly in LPS group and D+L group. However, compared with NS group, D group showed no significant difference in various indicators. Compared with LPS group, MPO, SOD, IL-1β and IL-18 were significantly decreased and MAP was significantly increased in D+L group. D+L group could significantly increase the level of Cav-1 protein and decrease the level of TLR-4 and NLRP3 protein in liver tissue caused by sepsis. The expression of Cav-1 mRNA was significantly up-regulated and the expression of TLR-4 and NLRP3 mRNA was inhibited in D+L group.

Conclusion: Dex pretreatment protects against LPS-induced actue liver injury via inhibiting the activation of the NLRP3 signaling pathway by up-regulating the expression of Cav-1 by sepsis.
Acute and Long-Term Services for Elementary and Middle School Children With Early Childhood Brain Injury
Authors: Salley Jessica , Crook Libby , Iske Taylor , Ciccia Angela , Lundine Jennifer P.
Published: February 2021

Purpose

The purpose of this study was to investigate the rates of referral to and receipt of acute and long-term services and identify factors that could impact these rates for children who experienced an acquired brain injury (ABI) during early childhood who are now in elementary and middle school.

Method

This was a retrospective chart review and prospective phone survey of 29 caregivers of children with ABIs.

Results

Acutely, two thirds of this sample received hospital-based rehabilitation services, but only 44.8% of families reported receiving ABI-specific education or a referral to educational or rehabilitation services at the time of discharge. At an average of 8.5 years postinjury, children in this sample were largely reported to be performing positively in school. While special education rates did not change significantly over time, 20.7% of the sample reported having unmet educational needs. Additionally, service receipt decreased over time. Various injury and educational factors influenced rates of long-term special education and service receipt.

Conclusions

This study contributes to the emerging literature focusing on long-term outcomes of children with ABI. The results reinforce that children who experience an ABI in early childhood are unlikely to receive ABI-specific education or referrals to educational and rehabilitation services during their acute-care stay and, in the chronic stages of recovery, present with educational and therapy needs that can go unmet. To improve long-term service access for children who experience an early ABI, pathways need to be established within the acute-care setting for education and referrals that connect the child and family to treatment within early intervention and educational systems. Maintaining these pathways long term, particularly for potential social-behavioral and cognitive-communication concerns, could increase access to appropriate services and, thus, decrease unmet needs for children with ABI.
Novel Adjective Processing in Preschool Children: Evidence From Event-Related Brain Potentials
Authors: Gerwin Katelyn L. , Leonard Laurence B. , Schumaker Jennifer , Deevy Patricia , Haebig Eileen , Weber Christine
Published: February 2021

Purpose

Recent findings in preschool children indicated novel adjective recall was enhanced when learned using repeated retrieval with contextual reinstatement (RRCR) compared to repeated study (RS). Recall was similar for learned pictures used during training and new (generalized) pictures with the same adjective features. The current study compared the effects of learning method and learned/generalized pictures on the neural processes mediating the recognition of novel adjectives.

Method

Twenty typically developing children aged 4;6–5;11 (years;months) learned four novel adjectives, two using RRCR and two using RS. Five-minute and 1-week tests assessed adjective recall using learned and generalized pictures. Also, at the 1-week visit, event-related potentials (ERPs) were recorded to assess children's processing of learned/generalized pictures, followed by naturally spoken novel adjectives in a match–mismatch paradigm.

Results

Naming recall and match–mismatch judgment accuracy were similar for the RS and RRCR conditions and across learned/generalized pictures. However, ERPs revealed more reliable condition effects in the phonological mapping negativity, indexing phonological expectations, and the late positive component, indexing semantic reanalysis, for the adjectives learned in the RRCR relative to the RS condition. Unfamiliar pictures (generalized) elicited larger amplitude N300 and N400 components relative to learned pictures.

Conclusions

Although behavioral accuracy measures suggest similar effects of the RS and RRCR learning conditions, subtle differences in the ERPs underlying novel adjective processing indicate advantages of RRCR for phonological processing and semantic reanalysis. While children readily generalized the novel adjectives, ERPs revealed greater cognitive resources for processing unfamiliar compared to learned pictures of the novel adjective characteristics.

Model‐predictive control‐based hybrid optimized load frequency control of multi‐area power systems
Authors: MV Mahendran , V Vijayan
Published: February 2021

It is distinguished that there should be a balance between power generation and load demand, thereby maintaining the frequency and tie‐line power of the multi‐source multi‐area interconnected power system (MS‐MA‐IPS) in a determined limit to safeguard the entire system from failure. Hence, load frequency control (LFC) by adjusting the megawatt output of generators is applied, which has been considered as the most recent research work in this field. Under these circumstances, this paper intends to construct a dual‐mode‐switch‐controller‐based LFC in a multi‐area power system, which obviously considers the impact of incremental control action along with the system dynamic constraints such as capacitive energy storage, generation rate constraint, and governor with dead band. In order to achieve this effect, in this research work, the operations of the proposed controller of the MS‐MA‐IPS are based on the dual‐mode switch, and here, switching is carried out with respect to a threshold value . Based on switching, the control varies between proportional–integral (PI) control and model‐predictive control. Moreover, in order to make the performance elegant, the proportional gain of the PI controller and the threshold of the switch are optimally tuned by introducing a novel optimisation algorithm referred to as particle updated dragonfly algorithm, which is the conceptual hybridisation of the traditional dragonfly algorithm and particle swarm optimisation. Finally, the performance of the proposed model is evaluated by varying the control parameters such as , , , and to minimize the undesired deviations in power flows between control areas.

The reactor coolant is lead and flowing through a circular straight channel, meanwhile, sCO2 is heated through 5 channels with different geometries were investigated respectively, including straight channel, zigzag 52° channel, S-shaped fins, offset rectangular fins, and airfoil fins. Considering the thermal-hydraulics characteristics, mechanical structure, corrosion, and flow blockage in the IHX designs, the performance, total cost, and power density of several heat exchanger designs were evaluated and compared. Finally, a printed circuit heat exchanger (PCHE) design using the circular straight (lead) - offset rectangular fins (sCO2) channels was proposed. The straight and S-shaped channels for sCO2 flow were recommended as alternative designs under certain circumstances. However, S-shaped fins and zigzag channels will dramatically increase the cost while straight and airfoil channels will greatly increase the volume.

Energy management of a dual-motor driven city bus based on reformed dynamic programming
Authors: Wang Wenwei , Pan Hong , Cheng Lin
Published: February 2021

This paper proposes a reformed dynamic programming (DP) based energy management strategy for a city bus driven by dual-motor coupling propulsion system(DMCPS). An instantaneous optimal problem of DMCPS’s total energy loss is constructed to solve the torque allocation between two motors. Taking the results as extra constraints, a reformed DP architecture aimed at optimal energy consumption is established, where the state variables are the battery’s SOC and operating modes of DMCPS, with a sole decision variable of mode switching action. The optimization results show a close performance to the original method, with the calculation efficiency greatly improved and the calculation time reduced by nearly 97%. To obtain practical rules for real-time application, the mode switching schedule is extracted based on a RBF-SVM classifier, and the torque allocation is ruled by linear function. Simulation results demonstrate that the extracted rules can be executed through an on-board processor, with energy consumption reduced by 2.19% compared to the original rule-based strategy.

Authors: Xianwei Ji
Published: February 2021

During the sedimentary period of Saertu reservoir on the western slope of the northern Songliao basin, delta front and shore-shallow lake subfacies are mainly developed, which have the characteristics of few sandstone layers and thin single layer thickness. The lithology of thin layer or thin interlayer can not be distinguished clearly by seismic response on conventional seismic section, and it is difficult to identify them. Geophysical response characteristics of channel sand bodies are defined by well-seismic combination. Under the guidance of seismic sedimentology, the qualitative and quantitative prediction of channel sand bodies is carried out by using 90°-phase conversion, stratal slicing and waveform indication inversion techniques. The results show that the seismic reflection axis is symmetrical with respect to the top and bottom surface of sandstone, and the channel sand body has obvious characteristics and completely corresponds to wave peak reflection. The channel bodies of S1 and S23 reservoir formation are separated respectively into two stages by using the amplitude attributes of stratal slices, and the coincidence rate of reservoir prediction to wells is 78%~84%, with an average of 79.7%. The waveform indicator inversion technique is used to predict the channel sand body thickness of the four stages, and the error of sand body thickness to well is 0~1.6m, with an average of 0.32m.

Form Deconstruction of Chinese Contemporary Landscape Architecture-Take the Design of Wuhan University of Technology Innovation and Entrepreneurship Park as an Example
Authors: Zou Zhe , Gan Ting , Yi Xiduo
Published: February 2021

There are several differences in architectural forms and cultural systems between the east and the west, which are attributed to different traditional philosophical ontologies. China takes "Tao" as its ideological basis emphasizes: "Nothing". Chinese fundamental principles are deeply related to philosophy and metaphysics. Traditional culture pursues spiritual connotations. Inversely, the west regards "Logos" as the origin of the world. This emphasizes the "being", with fundamental principles based in geometry, mathematics and science. The west has established a scientific spatial consciousness since the beginning of the Renaissance. It is based on mathematical relations and geometric principles, and focused on the pursuit of matter. "Logos" is an important aspect of Western philosophy, meaning that the “center”, the “source” or the “truth”, is a transcendental "presence." Pythagorean's mathematical theory and Plato's "rational" thinking are ultimately a variant of "Logos". The external imitation of nature in western classical gardens aims to explore the essence of nature. The separation of subject and object as the fundamental formula of Western philosophical epistemology has made mankind dominating nature for a long time. It leads to the deterioration of our living environment. Deconstructive philosophical thought is the subversion and criticism of the "Logos centralism" since ancient Greece. It eliminates the sense of "center" and the "subject-object dichotomy", which is the process of transforming "being" to "nothing". "Anthropocentrism" is disintegrated, when people and nature re-entered in an equal dialogue and symbiosis. Therefore, the symbiotic relationship between man and nature has been reshaped by the spirit of deconstruction. This is highly compatible with the ideological concept of "harmony between man and nature". The cultural spirit of harmony is precious in Chinese traditional philosophy.

Taking the design project of the Innovation Pioneer Park of Wuhan University of Technology as a casestudy, this paper analyses the morphological deconstruction characteristics and their cultural connotation to contemporary Chinese courtyard spaces. It explores a design language and method that breaks through the traditional thinking paradigm, bridging it to characteristics of a particular era as well as the aesthetic appeal. This is not a universal design paradigm, but an exploratory series of philosophical speculative processes, which in turn can inform a dynamic and sustainable development. It shows ideological essence of reminiscent of culture and spirit of the traditional Chinese landscape. Contemporary people’s world views should be manifest. By doing so, it becomes a conceptual, radiant and pioneering Chinese cultural spiritual symbol in a chaotic contemporary society.

Published: February 2021

This paper puts forward the concept of incentive utility, which converts the value of each attribute in multi-attribute decision-making into a unified index for measurement, thus simplifying multi-attribute decision-making. In this paper, a comprehensive evaluation model based on the TOPSIS of incentive utility is established. Through the establishment of incentive index, the utility of incentive and the calculation of ideal point of utility, the disadvantage of "ideal point is not ideal" in the TOPSIS is overcome. It can better synthesize the sub-attribute value and realize the subjective multi-attribute decision-making. The example shows that the model can apply subjective factors to decision-making scientifically, and the result is more reasonable and effective.
