Authors: Li Chuanbo , Wang Bo , Ouyang Yinggen , Yan Taihong , Zheng Weifang 
Published: August 2022

Abstract
The effects of feeding location on crystals size and distribution, precipitation percentage of Pu(IV) oxalate were investigated in a vortex continuous precipitator when the apparent average residence time was 25 min at 50 °C. The results showed that when oxalic acid was into the free vortex zone and Pu(IV) nitrate solution was into the forced vortex one, the VMD of the particles near the outlet of the precipitator increased from 36.8 ± 1.2 µm to 45.8 ± 2.1 µm, the precipitation percentage of Pu(IV) oxalate from 97.90% ± 1.0–99.79% ± 0.05%, compared with another feeding location, both oxalic acid and Pu(IV) nitrate solution into the forced vortex zone. The two feeding methods could both prevent Pu(IV) oxalate nuclei contacting the inner wall of the precipitator during nucleation. The results showed agglomeration happened during crystals growth even under stirring. Both local supersaturations and agglomeration decided particles size distribution and the average size of Pu(IV) oxalate.
Health Care Provider Networks: Are Insurers Better Off?
Authors: Mougeot Michel , Naegelen Florence 
Published: August 2022

Abstract
Certain health insurers offer a free choice of providers and an identical copayment regardless of the provider. Others build networks and use selective contracting and financial incentives to channel policyholders to contracted suppliers. In the case of unregulated prices, we compare these two policies when the off-network medical service is not covered. We show how policy ranking depends on the characteristics of demand. If demand is linear, a for-profit insurer and a not-for-profit insurer obtain a higher profit and utility under selective contracting than under uniform reimbursement. In the constant elasticity case, these results do not hold. Insurers prefer uniform reimbursement while consumers are better off under selective contracting in both cases.
Distinct characteristics of correlation analysis at the single-cell and the population level
Authors: Wu Guoyu , Li Yuchao 
Published: August 2022

Abstract
Correlation analysis is widely used in biological studies to infer molecular relationships within biological networks. Recently, single-cell analysis has drawn tremendous interests, for its ability to obtain high-resolution molecular phenotypes. It turns out that there is little overlap of co-expressed genes identified in single-cell level investigations with that of population level investigations. However, the nature of the relationship of correlations between single-cell and population levels remains unclear. In this manuscript, we aimed to unveil the origin of the differences between the correlation coefficients at the single-cell level and that at the population level, and bridge the gap between them. Through developing formulations to link correlations at the single-cell and the population level, we illustrated that aggregated correlations could be stronger, weaker or equal to the corresponding individual correlations, depending on the variations and the correlations within the population. When the correlation within the population is weaker than the individual correlation, the aggregated correlation is stronger than the corresponding individual correlation. Besides, our data indicated that aggregated correlation is more likely to be stronger than the corresponding individual correlation, and it was rare to find gene-pairs exclusively strongly correlated at the single-cell level. Through a bottom-up approach to model interactions between molecules in a signaling cascade or a multi-regulator-controlled gene expression, we surprisingly found that the existence of interaction between two components could not be excluded simply based on their low correlation coefficients, suggesting a reconsideration of connectivity within biological networks which was derived solely from correlation analysis. We also investigated the impact of technical random measurement errors on the correlation coefficients for the single-cell level and the population level. The results indicate that the aggregated correlation is relatively robust and less affected. Because of the heterogeneity among single cells, correlation coefficients calculated based on data of the single-cell level might be different from that of the population level. Depending on the specific question we are asking, proper sampling and normalization procedure should be done before we draw any conclusions.
“Hypophora” and “question cascade” in Cantonese political discourse: the stance triangle and the use of rhetorical moves and utterance final particles
Authors: Wan Helen 
Published: August 2022

Abstract
This paper looks into the specific pragmatic functions of Cantonese utterance final particles (UFPs) employed in a televised political debate, hosted by the Television Broadcasts Limited in 2016. The paper explores the most frequently used UFPs and discusses how they are being manipulated with two prominent questioning strategies, i.e., hypophora and question cascade, to help project negative stance in this highly institutionalized discourse genre. With the aid of the theoretical framework of ‘stance triangle’, I investigate how various stance-taking activities are navigated through the employment of two questioning strategies as well as UFPs to establish dis-alignment among the electoral candidates. The findings show that the most frequently used UFPs are le1 and aa3: these two UFPs are relatively neutral in question design in daily conversation and are used in all types of question such as polar questions, alternative questions, and content questions. The findings demonstrate that these particles serve as a mitigator and softener with the strategic use of hypophora and question cascade. This paper also proposes a revised stance triangle that helps understand how the negative stances are navigated in questioning strategies and realize the stance objects in an explicit manner. Discovering the true stance objects reveals that the question designs are usually oriented to the “remote audiences,”i.e. the voters.
A bibliographic survey of the supramolecular architectures sustained by delocalised C–I⋯π(arene) interactions in metal-organic crystals
Authors: Tiekink Edward R. T. 
Published: August 2022

Abstract
A survey of the crystallographic literature of metal-organic crystal structures for the presence of C–I···π(arene) interactions where the iodide atom occupies a position close to plumb to the ring centroid, corresponding to a delocalised interaction, and is within the assumed sum of the van der Waals radii, i.e. 3.88 Å, has been undertaken. The majority of the 26 identified examples feature supramolecular chains of varying topology whereby C–I···π(arene) contacts are readily identified and apparently operating independently of other obvious supramolecular synthons. The next most prevalent supramolecular aggregate was zero-dimensional, containing up to a maximum of three molecules. While there were three examples of two-dimensional arrays among a series of isostructural crystal structures, no examples of three-dimensional structures largely sustained by C–I···π(arene) interactions were noted. This distribution of supramolecular aggregation patterns matched that noted for all-organic systems. In terms of the overall adoption rate, delocalised C–I···π(arene) interactions were found in 3% of crystals of metal-organic species where they could form, a percentage lower than 4% noted for all-organic crystals.

Abstract
Davies, TB, Halaki, M, Orr, R, Mitchell, L, Helms, ER, Clarke, J, and Hackett, DA. Effect of set structure on upper-body muscular hypertrophy and performance in recreationally trained men and women. J Strength Cond Res 36(8): 2176–2185, 2022—This study explored the effect of volume-equated traditional-set and cluster-set structures on muscular hypertrophy and performance after high-load resistance training manipulating the bench press exercise. Twenty-one recreationally trained subjects (12 men and 9 women) performed a 3-week familiarization phase and were then randomized into one of two 8-week upper-body and lower-body split programs occurring over 3 and then progressing to 4 sessions per week. Subjects performed 4 sets of 5 repetitions at 85% one repetition maximum (1RM) using a traditional-set structure (TRAD, n = 10), which involved 5 minutes of interset rest only, or a cluster-set structure, which included 30-second inter-repetition rest and 3 minutes of interset rest (CLUS, n = 11). A 1RM bench press, repetitions to failure at 70% 1RM, regional muscle thickness, and dual-energy x-ray absorptiometry were used to estimate changes in muscular strength, local muscular endurance, regional muscular hypertrophy, and body composition, respectively. Velocity loss was assessed using a linear position transducer at the intervention midpoint. TRAD demonstrated a significantly greater velocity loss magnitude (g = 1.50) and muscle thickness of the proximal pectoralis major (g = −0.34) compared with CLUS. There were no significant differences between groups for the remaining outcomes, although a small effect size favoring TRAD was observed for the middle region of the pectoralis major (g = −0.25). It seems that the greater velocity losses during sets observed in traditional-set compared with cluster-set structures may promote superior muscular hypertrophy within specific regions of the pectoralis major in recreationally trained subjects.
Physiological Feature Recognition Algorithm of Human Exercise-Induced Fatigue Based on Parameter Analysis of Nanomachine Simulation for a Future Smart World
Authors: Chen Yujue , Hu He , Li Qiang 
Published: August 2022

Abstract
Traditional methods cannot fully reflect the fatigue degree of human exercise through a single parameter, which has the problems of long recognition time, high recognition coincidence, and poor anti-interference. Therefore, a physiological feature recognition algorithm of human exercise-induced fatigue based on parameter analysis of nanomachine simulation is proposed. The output value of body weight and a three-axis acceleration sensor are used to calculate the energy consumption parameters. By judging the time series period of fatigue physiological features data, the physiological features of human exercise-induced fatigue are extracted, and the feature extraction results are fused. According to the fusion results, the feature recognition is realized by analyzing the simulation parameters of nanomachine. The experimental results show that the shortest feature recognition time of the proposed method is 2.35 s, which is significantly lower than that of the traditional method, the feature recognition coincidence degree of the proposed method is lower, and the anti-interference performance is better, which fully shows that the method can accurately judge the degree of human exercise-induced fatigue.
Conservative management of complicated Rathke’s cleft cyst mimicking pituitary apoplexy
Authors: Constantinescu S M , Wilms G , Furnica R M , Duprez T , Maiter D 
Published: August 2022

Summary
Complicated Rathke’s cleft cyst (RCC) is a rare occurrence of symptomatic bleeding or growth of a previously asymptomatic (and often undiagnosed) intrasellar cyst derived from remnants of Rathke’s pouch, situated on the midline between the adeno- and neurohypophysis. Symptoms may be identical to those of pituitary apoplexy: acute onset of headache, hypopituitarism, and neurological disturbances. Both syndromes may also exhibit a similar appearance of a large haemorrhagic sellar mass at initial radiological evaluation. We report on two patients who presented with headache and complete hypopituitarism. Based on the initial MRI, they were first diagnosed with pituitary apoplexy but managed conservatively with hormone therapy alone because of the absence of severe visual or neurological threat. Upon follow-up at 4 months, clinical evolution was good in both patients but their pituitary mass had not reduced in size and, after careful radiologic reviewing, was more indicative of a large midline complicated RCC. In conclusion, the diagnosis of complicated RCC is challenging because it can mimic pituitary apoplexy clinically, biologically, and radiologically. Clinicians should distinguish between the two entities using specific radiological signs or evolution of the mass at MRI if the patient does not undergo surgery. To our knowledge, we report conservative management of this rare condition for the first time, though it seems appropriate in the absence of neurological compromise or visual compression. Long-term follow-up is however mandatory.

Learning points

Complicated Rathke’s cleft cyst can mimic pituitary apoplexy, presenting with sudden onset of headache, hypopituitarism, and visual and neurological compromise in the most severe cases.

At diagnosis, pituitary MRI may not be able to differentiate between the two entities, showing a large haemorrhagic mass inside the sella, with little or no normal pituitary tissue visible. Patients are often diagnosed with apoplexy at this stage and may undergo pituitary surgery.

When surgery has not been performed initially in these patients, repeat imaging at 3–6 months is unchanged and does not show the expected involution usually seen after adenoma apoplexy.

Conservative management with hormonal replacement seems a valid option in the absence of visual or neurological deficits that would require trans-sphenoidal surgery.
Early Molecular Events Mediating Loss of Aquaporin-2 during Ureteral Obstruction in Rats

Published: August 2022

Significance Statement
Acquired nephrogenic diabetes insipidus (NDI), a common polyuric disorder, is caused by the loss of aquaporin-2 (AQP2), but early mediating molecular events remain unclear. Our previous study of lithium-induced NDI showed NF-κB signaling and an inflammatory-like response that represses Aqp2 transcription. Here, we investigate early signaling responses triggered by unilateral ureteral obstruction (UUO) using small-sample RNA-Seq of microdissected rat renal cortical collecting ducts. Early global mRNA suppression followed by an inflammatory signaling response explains loss of AQP2 after UUO. Activation of inflammatory-like signaling may be a shared property of acquired NDI syndromes that leads to repression of Aqp2 gene expression.

Background
Ureteral obstruction is marked by disappearance of the vasopressin-dependent water channel aquaporin-2 (AQP2) in the renal collecting duct and polyuria upon reversal. Most studies of unilateral ureteral obstruction (UUO) models have examined late time points, obscuring the early signals that trigger loss of AQP2.

Methods
We performed RNA-Seq on microdissected rat cortical collecting ducts (CCDs) to identify early signaling pathways after establishment of UUO.

Results
Vasopressin V2 receptor (AVPR2) mRNA was decreased 3 hours after UUO, identifying one cause of AQP2 loss. Collecting duct principal cell differentiation markers were lost, including many not regulated by vasopressin. Immediate early genes in CCDs were widely induced 3 hours after UUO, including Myc, Atf3, and Fos (confirmed at the protein level). Simultaneously, expression of NF-κB signaling response genes known to repress Aqp2 increased. RNA-Seq for CCDs at an even earlier time point (30 minutes) showed widespread mRNA loss, indicating a “stunned” profile. Immunocytochemical labeling of markers of mRNA-degrading P-bodies DDX6 and 4E-T indicated an increase in P-body formation within 30 minutes.

Conclusions
Immediately after establishment of UUO, collecting ducts manifest a stunned state with broad disappearance of mRNAs. Within 3 hours, there is upregulation of immediate early and inflammatory genes and disappearance of the V2 vasopressin receptor, resulting in loss of AQP2 (confirmed by lipopolysaccharide administration). The inflammatory response seen rapidly after UUO establishment may be relevant to both UUO-induced polyuria and long-term development of fibrosis in UUO kidneys.
Self-concept of EFL preservice teachers as reflected in their teaching performance
Authors: Rachmawati Dina 
Published: August 2022

A number of studies discussing the significant role of self-concept in the educational field are evident. However, research investigating the self-concept of English as a Foreign Language (EFL) preservice teachers and how the self-concept is reflected in the teaching performance is limited. Thus, this study was aimed at investigating the portrait of the self-concept of English preservice teachers in the Indonesian context and how the self-concept is reflected in their teaching performance. A qualitative research paradigm, especially an explanatory case study design was employed to figure them out. The study found that first, diverse portraits of self-concept i.e. highly positive, moderate, and low or negative self-concept were captured in the participants’ academic self-concept (pedagogic and professional self-concept) with the inclination of higher portrayal in the non-academic sub-aspects of self-concept (social and emotional self-concept). Second, the congruent and incongruent reflection of self-concept were identified. The findings imply that academic aspects of self-concept (pedagogic and professional competence) seem to be contributing factors to the participants’ negative self-perception of their self-concept. Moreover, reflexivity, internal and external frames of reference, and emotion regulation strategies seem to be contributing factors to the construction of the participants’ self-concept. This study concludes that the construction of the participants’ self-concept dynamic during the practicum and its manifestation in the teaching performance is affected by internal and external factors.

Published: August 2022

The Circle Diagram was used in past for the performance evaluation of 3-phase induction motor under different load conditions. But, now it is not preferred due to availability of programs for detailed analysis. The per-phase equivalent circuit is also not that suitable to estimate the dynamic performance. In this paper, a method is suggested to determine the performance using dq-model. The objective of this paper is to describe modelling in terms of dq variables. The analysis under steady state condition is done using numerical technique tools. The numerical tools such as Gauss-Seidel and Successive Relaxation methods are used and the results are compared with that obtained from the experiment conducted in the laboratory. The comparison of results confirms the validity as well as the accuracy of the proposed methods, as yet another approach to predetermine the performance.
