Abstract
This study aimed to do the inventory on ant species (Hymenoptera: Formicidae) that specifically inhabit the bird nests within the Universitas Andalas campus complex, Limau Manis, Padang. It had been conducted from January to August 2018, where the bird nests were purposively collected then followed with ant collection from each nest. Forty nests were sampled and identified as nests of Estrildidae, Pycnonotidae, Sylviidae and from the unknown taxa; 5 nests showed active breeding indications when collected. A total of 2,741 ant individuals belong to 13 species, 12 genera, 8 tribes, and 4 subfamilies extracted from 31 (of which 4 were active nests), out of 40, observed nests. The ant species inventory included the members of subfamilies Formicinae (5), Myrmicinae (5), Dolichoderinae (2) and Pseudomyrmicinae (1). We statistically detected correlation between nest biomass and number of ant individual and species infested in the bird nests, which explained the more species recorded from Estrildid nests that were averagely bulkier than other nests. This result offers strong indication that bird nests may serve as form of habitat, or at least a niche, for ants.

Abstract
Since variations in chrysanthemums are still limited, Indonesia still imports. An effort to expand the variation can be done through polyploidy techniques using colchicine. Pasopati varieties of the chrysanthemum were propagated in vitro and treated with colchicine and planted in different media compositions to observe performance and obtain superior genotype. Experiment with a factorial pattern that consist of two factors: the composition of the planting medium ( m1 = top soil, m2 = cocopeat, m3 = husk charcoal, m4 = top soil + cocopeat m5 = top soil + husk charcoal, m6 = cocopeat + chaff charcoal) and polyploidy chrysanthemum genotypes (g1 = KAR0, g2 = KAR1, g3 = KAR2, g4 = KAR3, and g5 = KAR4) with two replications was designed. The results showed there were variations in plant height, stem diameter, number of nodes, number of floret, and stalk length on polyploidy Chrysanthemum genotypes due to different planting media. The m4 = top soil + cocopeat can increase plant height, stem diameter, number of nodes, stalk length and number of floret KAR4 genotype.

AbstractClimate change (CC) is real and threatens the livelihood of most smallholder farmers who reside along the coastal area. The CC causes the rise of temperature (0.2-0.3°C/decade) and sea level (SRL = 5 mm/year), drought and floods to occur more frequently, the change of rainfall intensity and pattern and shifting of planting season and leads to the decreasing of crop yield or yield loss. Most of the paddy soil has been exhausted and degraded. About 50% of the rice field along the coastline is effected by high salinity and causes significant yield losses. The research was aimed to summarize the results of the system of organic based aerobic rice intensification (known as IPATBO) and of two climate filed school (CFS) in Cinganjeng and Rawapu that situated along the coastline of Pangandaran and Cilacap. Both IPATBO and CFS have adopted the strategy of climate-resilient sustainable agriculture (CRSA) for restoring the soil health and increasing rice productivity, and as well as to empower the farmer community. The implementation of IPATBO (2010-2020) in the different areas has increased the soil health, fertilizers, and water efficiency (reduce inorganic by 25-50%, and water by 30-40%) and increased rice productivity by at least 25-50%. Both CFS in Ciganjeng and Rawaapu were able to improve soil fertility, increase rice productivity, and farmer capacity. This result concludes the agro-ecological based CRSA and CFS can be adopted for the increasing the resilient of agricultural practices and farmers in adapting to climate change

Abstract
In the recent years, there is a need for the evolution of methodologies for vibrational analysis by condition monitoring. In this regard, wavelet analysis has become a tool to efficiently detect the features of any vibration signal. The application of wavelet analysis for finding fault in the belt drive is presented in this paper. Vibration signal has been obtained from a healthy and faulty belt drive using a belt drive testing apparatus for experimental studies. The fault diagnostic capability of wavelet analysis has been compared by processing an experimental data. The experiment is done for various working conditions of belt drive. The advantages of wavelet analysis is shown in comparison with Fast Fourier Transform.

Published: November 2021

Abstract
The article deals with the problem of calculating an heterogeneous cylindrical shell made of a filled polymer, which is in the process of creep under the action of constant internal pressure and temperature. The calculation is based on the Maxwell -Gurevich equation, which has been repeatedly tested in the calculations of structural elements made of polymer and composite materials. The dependence of the physical and mechanical characteristics of the material on temperature is taken into account.
Cluster Connectivity And Super Cluster Connectivity Of DQcube
Authors: Zhou Qianru , Zhou Shuming , Liu Xiaoqing , Yu Zhengqin 
Published: November 2021

AbstractAs a fundamental metric, the connectivity to assess fault tolerance and reliability of interconnection networks has been extensively explored. However, classical connectivity is not very effective at evaluating large-scale networking systems. To overcome this deficiency, two new indices, cluster connectivity and super cluster connectivity, have been proposed to characterize the robustness of interconnection networks. This paper focuses on investigating $\mathcal{H} (\mathcal{H}^{*})$-cluster connectivity and super $\mathcal{H} (\mathcal{H}^{*})$-connectivity of composition graph $DQ_{n}$, based on disc-ring and hypercube, for $\mathcal{H}\in \{K_{1,r}\ |\ 0\leq r\leq n+1\}$, respectively. In detail, we show that $\kappa (DQ_{n}|K_{1,1} (K_{1,1}^{*}))=\kappa ^{\prime}(DQ_{n}|K_{1,1}(K_{1,1}^{*})) =n+1 (n\geq 3)$, $\kappa (DQ_{n}|K_{1,r}(K_{1,r}^{*})) =\left\lceil \frac{n}{2}\right\rceil +1 (2\leq r\leq 4)$ for $n\geq 3$, $\kappa ^{\prime}(DQ_{n}|K_{1}(K_{1}^{*})) =\kappa ^{\prime}(DQ_{n})=2n (n\geq 3)$, and for $2\leq r\leq 3$ and $k\geq 2$, $$\begin{align*} \kappa^{\prime}(DQ_{n}|K_{1,r}(K_{1,r}^{*}))=\left\{\begin{array}{@{}ll} n+1, & if\ n=2k+1; \\ n, & if\ n=2k. \end{array}\right. \end{align*}$$As by-products, we show that DQcube is super $K_{1,r}-\ (K_{1,r}^{*}-)$connected $(2\leq r\leq 3)$, and derive the 4-extra connectivity of DQcube $\kappa _{4}(DQ_{n}) = 5n-9 (n\geq 4)$.

Abstract

OBJECTIVES
Spread through air spaces (STAS) is a unique pattern of invasion in primary lung cancers. However, little is known about STAS in pulmonary metastases (PMs). This study was to investigate the incidence of STAS among PMs and the association between STAS and clinicopathological characteristics of PMs.

METHODS
A total of 127 patients who underwent metastasectomy at our institution from June 2009 to December 2019 were retrospectively analysed. Survival analysis was performed in 40 patients with PM from colorectal cancer (CRC).

RESULTS
STAS was identified in 33.1% of patients (42 of 127) with PMs. STAS was found in PMs of various primary cancers, including CRC, breast cancer, renal cell carcinoma, cholangiocarcinoma and osteogenic and soft tissue sarcoma, but the incidence varies. PMs originating from epithelial tissue showed higher incidence of STAS than those from mesenchymal tissue (45% vs 11%, P &lt; 0.001). Elder age (P = 0.006) and primary sites (P &lt; 0.001) were significantly correlated with STAS. In patients with PMs from CRC, the presence of STAS was an independent predictor of shorter recurrence-free survival (hazard ratio = 10.25, P = 0.002) and poor overall survival (hazard ratio = 4.75, P = 0.047) by multivariable analysis.

CONCLUSIONS
STAS might be a lung-specific tumour invasion pattern and STAS is commonly observed in PMs of different origins. The incidence of STAS was significantly higher in PMs originating from epithelial tissues than those from mesenchymal tissues. Presence of STAS was an independent predictor of poor prognosis in patients with PM from CRC.

Abstract

Aims
REVEAL was the first randomized controlled trial to demonstrate that adding cholesteryl ester transfer protein inhibitor therapy to intensive statin therapy reduced the risk of major coronary events. We now report results from extended follow-up beyond the scheduled study treatment period.

Methods and results
A total of 30 449 adults with prior atherosclerotic vascular disease were randomly allocated to anacetrapib 100 mg daily or matching placebo, in addition to open-label atorvastatin therapy. After stopping the randomly allocated treatment, 26 129 survivors entered a post-trial follow-up period, blind to their original treatment allocation. The primary outcome was first post-randomization major coronary event (i.e. coronary death, myocardial infarction, or coronary revascularization) during the in-trial and post-trial treatment periods, with analysis by intention-to-treat. Allocation to anacetrapib conferred a 9% [95% confidence interval (CI) 3–15%; P = 0.004] proportional reduction in the incidence of major coronary events during the study treatment period (median 4.1 years). During extended follow-up (median 2.2 years), there was a further 20% (95% CI 10–29%; P &lt; 0.001) reduction. Overall, there was a 12% (95% CI 7–17%, P &lt; 0.001) proportional reduction in major coronary events during the overall follow-up period (median 6.3 years), corresponding to a 1.8% (95% CI 1.0–2.6%) absolute reduction. There were no significant effects on non-vascular mortality, site-specific cancer, or other serious adverse events. Morbidity follow-up was obtained for 25 784 (99%) participants.

Conclusion
The beneficial effects of anacetrapib on major coronary events increased with longer follow-up, and no adverse effects emerged on non-vascular mortality or morbidity. These findings illustrate the importance of sufficiently long treatment and follow-up duration in randomized trials of lipid-modifying agents to assess their full benefits and potential harms.

Published: November 2021

Abstract
This exploration aims to study the comparison of heat transfer capabilities of two nanofluid oblique, steady stagnation-point flow combinations comprising single-walled carbon/water (SWCNHs/water) and multiwalled carbon nanotube/water (MWCNTs/water) toward a stretching surface influenced by nonlinear thermal radiation employing the Xue model. This envisaged comparison model is inimitable and still scarce in the literature. Relying on the Tiwari–Das nanofluid model, a mathematical framework is constructed. The system of partial differential equations is converted using suitable transformations into an ordinary differential system of three equations, which is evaluated numerically using the bvp4c method. The physical behavior of significant parameters and their graphical representation are thoroughly examined. The results show that the SWCNHs/water nanofluid outperforms the MWCNTs/water nanofluid. It is further witnessed that SWCNH nanoparticle contained nanofluid has considerably greater thermal radiation than MWCNT nanoparticles. The envisaged model is also validated by comparing it with a published study.

ABSTRACT
When a star passes close to a supermassive black hole (BH), the BH’s tidal forces rip it apart into a thin stream, leading to a tidal disruption event (TDE). In this work, we study the post-disruption phase of TDEs in general relativistic hydrodynamics (GRHD) using our GPU-accelerated code h-amr. We carry out the first grid-based simulation of a deep-penetration TDE (β = 7) with realistic system parameters: a black hole-to-star mass ratio of 106, a parabolic stellar trajectory, and a non-zero BH spin. We also carry out a simulation of a tilted TDE whose stellar orbit is inclined relative to the BH midplane. We show that for our aligned TDE, an accretion disc forms due to the dissipation of orbital energy with ∼20 per cent of the infalling material reaching the BH. The dissipation is initially dominated by violent self-intersections and later by stream–disc interactions near the pericentre. The self-intersections completely disrupt the incoming stream, resulting in five distinct self-intersection events separated by approximately 12 h and a flaring in the accretion rate. We also find that the disc is eccentric with mean eccentricity e ≈ 0.88. For our tilted TDE, we find only partial self-intersections due to nodal precession near pericentre. Although these partial intersections eject gas out of the orbital plane, an accretion disc still forms with a similar accreted fraction of the material to the aligned case. These results have important implications for disc formation in realistic tidal disruptions. For instance, the periodicity in accretion rate induced by the complete stream disruption may explain the flaring events from Swift J1644+57.

AbstractInvestigating chromatin interactions between regulatory regions such as enhancer and promoter elements is vital for understanding the regulation of gene expression. Compared to Hi-C and its variants, the emerging 3D mapping technologies focusing on enriched signals, such as TrAC-looping, reduce the sequencing cost and provide higher interaction resolution for cis-regulatory elements. A robust pipeline is needed for the comprehensive interpretation of these data, especially for loop-centric analysis. Therefore, we have developed a new versatile tool named cLoops2 for the full-stack analysis of these 3D chromatin interaction data. cLoops2 consists of core modules for peak-calling, loop-calling, differentially enriched loops calling and loops annotation. It also contains multiple modules for interaction resolution estimation, data similarity estimation, features quantification, feature aggregation analysis, and visualization. cLoops2 with documentation and example data are open source and freely available at GitHub: https://github.com/KejiZhaoLab/cLoops2.
The Great Dialectic
Authors: Brandt Loren , Thun Eric 
Published: November 2021

Abstract
This chapter examines China’s mixed upgrading and innovation record in the context of the ongoing debate over the role of the state vis-à-vis the market. A key finding that emerges is that sectors that have been most open to competition, in which entry and exit are less encumbered and, more generally, in which firms have been free from the often-distorting hand of the Chinese state, are those that have been most successful in cultivating domestic firms able to compete domestically and globally. Central to our assessment is how firms in these sectors have been better able to leverage China’s rapidly growing domestic market to their competitive advantage in the course of their upgrading and innovation efforts.

AbstractThe ability to trace every cell in some model organisms has led to the fundamental understanding of development and cellular function. However, in plants the complexity of cell number, organ size, and developmental time makes this a challenge even in the diminutive model plant Arabidopsis (Arabidopsis thaliana). Duckweed, basal nongrass aquatic monocots, provide an opportunity to follow every cell of an entire plant due to their small size, reduced body plan, and fast clonal growth habit. Here we present a chromosome-resolved genome for the highly invasive Lesser Duckweed (Lemna minuta) and generate a preliminary cell atlas leveraging low cell coverage single-nuclei sequencing. We resolved the 360 megabase genome into 21 chromosomes, revealing a core nonredundant gene set with only the ancient tau whole-genome duplication shared with all monocots, and paralog expansion as a result of tandem duplications related to phytoremediation. Leveraging SMARTseq2 single-nuclei sequencing, which provided higher gene coverage yet lower cell count, we profiled 269 nuclei covering 36.9% (8,457) of the L. minuta transcriptome. Since molecular validation was not possible in this nonmodel plant, we leveraged gene orthology with model organism single-cell expression datasets, gene ontology, and cell trajectory analysis to define putative cell types. We found that the tissue that we computationally defined as mesophyll expressed high levels of elemental transport genes consistent with this tissue playing a role in L. minuta wastewater detoxification. The L. minuta genome and preliminary cell map provide a paradigm to decipher developmental genes and pathways for an entire plant.

Abstract
Plasma membrane (PM) H+-ATPase in guard cells is activated by phosphorylation of the penultimate residue, threonine (Thr), in response to blue and red light, promoting stomatal opening. Previous in vitro biochemical investigation suggested that Mg2+- and Mn2+-dependent membrane-localized type 2C protein phosphatase (PP2C)-like activity mediates the dephosphorylation of PM H+-ATPase in guard cells. PP2C clade D (PP2C.D) was later demonstrated to be involved in PM H+-ATPase dephosphorylation during auxin-induced cell expansion in Arabidopsis (Arabidopsis thaliana). However, it is unclear whether PP2C.D phosphatases are involved in PM H+-ATPase dephosphorylation in guard cells. Transient expression experiments using Arabidopsis mesophyll cell protoplasts revealed that all PP2C.D isoforms dephosphorylate the endogenous PM H+-ATPase. We further analyzed PP2C.D6/8/9, which display higher expression levels than other isoforms in guard cells, observing that pp2c.d6, pp2c.d8, and pp2c.d9 single mutants showed similar light-induced stomatal opening and phosphorylation status of PM H+-ATPase in guard cells as Col-0. In contrast, the pp2c.d6/9 double mutant displayed wider stomatal apertures and greater PM H+-ATPase phosphorylation in response to blue light, but delayed dephosphorylation of PM H+-ATPase in guard cells; the pp2c.d6/8/9 triple mutant showed similar phenotypes to those of the pp2c.d6/9 double mutant. Taken together, these results indicate that PP2C.D6 and PP2C.D9 redundantly mediate PM H+-ATPase dephosphorylation in guard cells. Curiously, unlike auxin-induced cell expansion in seedlings, auxin had no effect on the phosphorylation status of PM H+-ATPase in guard cells.
