On the number of automorphisms of a regular graph

For any connected cubic graph G with 2n points, the number of automorphisms of G divides 3n2n. This is a special case of a result which is proved for connected regular graphs in general. The result is shown to be best possible for infinitely many n in the cubic case. An r-regular graph is a graph G in which each point is of degree r; if r = 3 we say G is cubic. We have shown elsewhere [6] that the number of labelled connected cubic graphs with 2n points is divisible by (2n)! /(3n2'), as are the numbers of labelled 2-connected and 3-connected cubic graphs. This was done by obtaining recurrence relations for the numbers involved. Our main concern is to verify this result directly by showing that the number of ways to label any connected cubic graph with 2n points is divisible by (2n)! /(3n2'). Let s denote the order of the automorphism group F(G) of the graph G. If G is cubic and has 2n points, it follows [5] that the number of ways to label G is just (2n)! /s. Thus, our aim is fulfilled if we show that s divides 3n2n. The following theorem is a generalisation of this result. All basic graph theoretic notation not defined here can be found in [4]. THEOREM 1. Let G be a connected r-regular graph with p points where r > 0. Then the number s of automorphisms of G divides
Effectiveness of Mobility and Stability Exercises in Resistance-Trained Males with Shoulder Immobility in Different Age Groups

Background. Resistance-trained males aim to increase their overall health, strength and fitness level. Many resistance-trained males aiming to increase their strength neglect the muscles that stabilize the scapular and glenohumeral joints. The shoulder joint is among the most frequently injured areas in resistance-trained males. In addition, strength training displays different effects in young and old individuals. The study purpose was to investigate the effects of stability and mobility exercises on range of motion, posture and body awareness in resistance-trained males with shoulder immobility. Materials and methods. Thirty-two resistance-trained males diagnosed with shoulder immobility were divided into two groups according to their age ranges (G1: Adult, G2: Young Adult). The program consisting of mobility and stability exercises was applied 3 days a week for 8 weeks. The participants were evaluated with a universal goniometer, the New York Posture Rating, and the Body Awareness Questionnaire before and after the treatment lasting 8 weeks. Results. Following the 8-week treatment, improvements in body awareness and range of motion were observed in all participants (p≤0.05). There were improvements in the scores of the New York Posture Rating and Body Awareness Questionnaire in both groups, but they were not statistically significant (p≥0.05). Conclusions. An exercise program combining stability and mobility exercises was applied to resistance-trained males with shoulder immobility and it was observed to have positive effects on the range of motion of the joint, body awareness and posture. We are of the opinion that various types of exercise should be implemented when planning exercise programs.
Shelling of Homogeneous Media

A homogeneous medium is characterised by a point set in Euclidean space (for the atomic positions, say), together with some self-averaging property. Crystals and quasicrystals are homogeneous, but also many structures with disorder still are. The corresponding shelling is concerned with the number of points on shells around an arbitrary, but fixed centre. For non-periodic point sets, where the shelling depends on the chosen centre, a more adequate quantity is theaveraged shelling, obtained by averaging over points of the set as centres. For homogeneous media, such an average is still well defined, at least almost surely (in the probabilistic sense). Here, we present a two-step approach for planar model sets.
Posterior Polymorphous Corneal Dystrophy in a Patient with a Novel ZEB1 Gene Mutation

Posterior polymorphous corneal dystrophy (PPCD), a rare, bilateral, autosomal-dominant, inherited corneal dystrophy, affects the Descemet membrane and corneal endothelium. We describe an unusual presentation of PPCD associated with a previously unknown genetic alteration in the ZEB1 gene. The proband is a 64-year-old woman diagnosed with keratoconus referred for a corneal endothelium study who presented endothelial lesions in both eyes suggestive of PPCD, corectopia and iridocorneal endothelial synechiae in the right eye and intrastromal segments in the left eye. The endothelial count was 825 in the right eye and 1361 in the left eye, with typical PPCD lesions visible under specular and confocal microscopy. In the next generation sequencing genetic analysis, a heterozygous c.1A > C (p.Met1Leu) mutation was found in the ZEB1 gene (TCF8). The PPCD3 subtype is associated with corneal ectasia, and both can appear due to a pathogenic mutation in the ZEB1 gene (OMIM #189909). However, our patient had a previously unreported mutation in the ZEB1 gene, which mediates the transition between cell lines and provides a pathogenic explanation for the epithelialisation of the corneal endothelium, a characteristic of PPCD.
Two-Phase Flow Pattern Map pada Pipa Horizontal dengan Permukaan Halus (Review Paper)

Untuk mengetahui pola (rejim) aliran dua fase yang mengalir pada suatu pipa, sampai sekarang terdapat dua metode yang dapat dilakukan yaitu dengan menggunakan high speed camera dan memprediksinya dengan menggunakan flow pattern map. Banyak penelitian terkait perancangan two-phase flow pattern map dilakukan dikarenakan mahalnya teknologi high speed camera ini yang membuat tidak semua peneliti dapat memiliknya. Pada penelitian ini, dilakukan sebuah review berbagai jurnal terkait penelitian two-phase flow pattern map aliran yang mengalir pada pipa horizontal dengan permukaan halus. Dari 18 jurnal dari berbagai peneliti dengan berbagai keadaan yang telah direview, didapat beberapa hasil yang didapatkan diantaranya : dengan berjalannya waktu diketahui bahwa penggunaan fluida kerja dalam penelitian berkembang dari air dan udara menjadi refrijeran, pipa yang digunakan semakin mengecil diameternya, dan dalam penelitiannya divalidasi dengan menggunakan high speed camera. Kemudian flow pattern map versi dahulu dikhawatirkan menimbulkan delay yang besar apabila dipaksa memprediksi data penelitian dengan fluida kerja refrijeran dan pipa skala mikro. Dari penelitian review ini dapat disimpulkan bahwa flow pattern map versi Wojtan et al. [11] dianggap reliable dan memungkinkan untuk digunakan pada penelitian-penelitian berikutnya.
Noncoding RNAs in Vascular Cell Biology and Restenosis

Simple Summary Angioplasty is a procedure where a stent is inserted to open a blocked blood vessel that is causing issues for a patient. Restenosis is a medical condition that reverses the benefits of angioplasty, and it is caused by injury from the stent, with inflammation, excessive smooth muscle cell growth and the movement of cells to accumulate inside the vessel, as part of a disproportionate healing response to the foreign object. The current treatments for restenosis stop the growth of all cells in the area, which is an issue as endothelial cells are required to keep growing in order to heal the inner layer of the blood vessel, which was damaged by the stent, and prevent issues in the future, such as blood clots. Noncoding RNAs are small pieces of genetic material that are not translated into proteins; however, they are important in controlling different biological processes, some of which are the growth and movement of specific cells involved in restenosis. Therefore, we may be able to target certain noncoding RNAs to only slow down the growth and movement of the type of cell causing the condition, namely smooth muscle cells, while allowing for endothelial cells to keep growing and healing the blood vessel. Abstract In-stent restenosis (ISR), characterised by ≥50% re-narrowing of the target vessel, is a common complication following stent implantation and remains a significant challenge to the long-term success of angioplasty procedures. Considering the global burden of cardiovascular diseases, improving angioplasty patient outcomes remains a key priority. Noncoding RNAs (ncRNAs) including microRNA (miRNA), long noncoding RNA (lncRNA) and circular RNA (circRNA) have been extensively implicated in vascular cell biology and ISR through multiple, both distinct and overlapping, mechanisms. Vascular smooth muscle cells, endothelial cells and macrophages constitute the main cell types involved in the multifactorial pathophysiology of ISR. The identification of critical regulators exemplified by ncRNAs in all these cell types and processes makes them an exciting therapeutic target in the field of restenosis. In this review, we will comprehensively explore the potential functions and underlying molecular mechanisms of ncRNAs in vascular cell biology in the context of restenosis, with an in-depth focus on vascular cell dysfunction during restenosis development and progression. We will also discuss the diagnostic biomarker and therapeutic target potential of ncRNAs in ISR. Finally, we will discuss the current shortcomings, challenges, and perspectives toward the clinical application of ncRNAs.
Use of Heating Methods and Xylose to Increase Rumen Undegradable Protein of Alternative Protein Sources: 2) Cottonseed Meal

Simple Summary Scientists constantly seek techniques that may improve animal-feed usage, because they can reduce environmental impact and increase the profitability of feedlot systems. In beef-cattle production systems, high-performance animals need a greater protein supply that escapes rumen fermentation to be digested in the intestine compared to low-performance animals. This fraction is called rumen undegradable protein (RUP). Cottonseed meal is a possible protein source with an excellent amino-acid profile; however, cottonseed meal has low RUP content, which can be increased by applying heat and xylose. Thus, we submitted this feed to different heat techniques (autoclave, conventional, and microwave ovens), with and without xylose treatment, to increase its RUP content. Our results suggest that the evaluated processing methods may increase cottonseed meal RUP. The best treatments under the experimental conditions were: for the autoclave, xylose-treated cottonseed meal with 8 and 16 min heating; for conventional oven, 90 min heating for xylose-treated cottonseed meal; and for the microwave oven, xylose-treated cottonseed meals with 2, 4, and 6 min heating. Further studies are necessary to confirm the results found here and evaluate the effects of these processed ingredients on ruminal fermentation parameters, animal performance, and economic viability. Abstract The ruminal kinetics of protein sources may be changed by heat and sugar treatments. Thus, these processing methods may be used as alternatives to increase beef-cattle diets’ rumen undegradable protein (RUP). We aimed to evaluate the effects of processing cottonseed meals with autoclave, conventional, and microwave ovens, with and without using xylose, on the ruminal kinetics degradation parameters and intestinal digestibility (ID). In situ studies were conducted, and each sample was incubated in the rumen to determine dry matter (DM) and crude protein (CP) rumen degradation kinetics. In vitro studies were also conducted to evaluate ID. The control treatment had a greater soluble fraction for DM and CP than processed cottonseed meals (p < 0.05). The addition of xylose decreased both DM and CP water-soluble fractions (fraction A) of cottonseed meal heated in a conventional oven (p < 0.05). Compared to the control, we observed a decrease in effective degradability and increased RUP for all processed methods (p < 0.05). Furthermore, conventional and microwave ovens showed greater ID than the control. Moreover, xylose-treated groups heated in the autoclave and conventional ovens had greater ID than xylose-untreated cottonseed meal. Under these experimental conditions, cottonseed RUP was increased by the evaluated processing methods.
A 95.2% Efficiency DC–DC Boost Converter Using Peak Current Fast Feedback Control (PFFC) for Improved Load Transient Response

The load transient response and unity gain bandwidth of DC-DC boost converters are primarily restricted by the presence of a right half plane zero (RHPZ). In this paper, a control scheme termed peak current fast feedback control (PFFC) is proposed to improve the load transient response without the need for additional power switches or passive components. In the proposed PFFC method, the closed loop output impedance (<inline-formula> <tex-math notation="LaTeX">$Z_{OCL}$ </tex-math></inline-formula>) is improved by reducing the DC value and by increasing the bandwidth of <inline-formula> <tex-math notation="LaTeX">$Z_{OCL}$ </tex-math></inline-formula> as compared to conventional peak current mode control (CPCM), thus improving the steady state and transient performance. The fast feedback (FFB) path is implemented within the error amplifier (EA) with an increase of only 2% in the active area as compared to CPCM. The boost converter is designed for <inline-formula> <tex-math notation="LaTeX">$V_{OUT} =5\text{V}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$V_{IN} =2.5\text{V}$ </tex-math></inline-formula>-4.4V and <inline-formula> <tex-math notation="LaTeX">$I_{LOAD} =10$ </tex-math></inline-formula>mA-1A operating at a fixed frequency of 2MHz. Measurement results show that with PFFC enabled, the settling time reduces by <inline-formula> <tex-math notation="LaTeX">$\sim 2.6\times $ </tex-math></inline-formula> and the undershoot reduces by 62% to <inline-formula> <tex-math notation="LaTeX">$12~\mu \text{s}$ </tex-math></inline-formula> and 41mV respectively when compared to CPCM for 10mA to 1A load step at 2A/<inline-formula> <tex-math notation="LaTeX">$\mu \text{s}$ </tex-math></inline-formula>. The converter achieves a peak efficiency of 95.2% at 0.5W output power with <inline-formula> <tex-math notation="LaTeX">$V_{IN} =4.4\text{V}$ </tex-math></inline-formula> and load regulation of 9mV/A at <inline-formula> <tex-math notation="LaTeX">$V_{IN} =2.5\text{V}$ </tex-math></inline-formula>.
Determination of Conformational and Functional Stability of Potential Plague Vaccine Candidate in Formulation

Generally, protein-based vaccines are available in liquid form and are highly susceptible to instability under elevated temperature changes including freezing conditions. There is a need to create a convenient formulation of protein/peptides that can be stored at ambient conditions without loss of activity or production of adverse effects. The efficiency of naturally occurring biocompatible polymer dextran in improving the shelf-life and biological activity of a highly thermally unstable plague vaccine candidate protein called Low Calcium Response V antigen (LcrV), which can be stored at room temperature (30 ± 2 °C), has been evaluated. To determine the preferential interactions with molecular-level insight into solvent–protein interactions, analytical techniques such asspectroscopy, particle size distribution, gel electrophoresis, microscopy, and thermal analysis have been performed along with the evaluation of humoral immune response, invivo. The analytical methods demonstrate the structural stability of the LcrV protein by expressing its interaction with the excipients in the formulation. The invivo studies elicited the biological activity of the formulated antigen with a significantly higher humoral immune response (p-value = 0.047) when compared to the native, adjuvanted antigen. We propose dextran as a potential biopolymer with its co-excipient sodium chloride (NaCl) to provide protein compactness, i.e., prevent protein unfolding by molecular crowding or masking mechanism using preferential hydrophobic interaction for up to three weeks at room temperature (30 ± 2 °C).
Rates of Poisson Approximation to Finite Range Random Fields

The Stein-Chen approach is used to obtain bounds on the Poisson approximation of a random field, in both a random variable and a stochastic process sense. The hypotheses are Dobrushin's condition or, alternatively, positive dependence combined with a bound on decay of correlations. Rates of convergence are derived which supplement the limit theorems of Berman. The results have application to certain Gibbs states at both high and low temperature.
Assessment of seedling traits of rice landraces under different saline conditions

Salinity is one of the major abiotic stresses affecting rice growth and yield worldwide. In rice, the most critical stages which affect salinity at a greater level are germination, vegetative and reproductive stages.It is very important to know the genotypic variation among landraces under saline conditions at the seed germination stage to reduce the harmful effect of salinity. The present study conducted on Petri plate was mainly for assessing germination, relative water content and seedling parameters of eleven rice landraces with check landrace Pokali under three different salt concentrations (75mM, 125mM and 150mM). Two-way ANOVA gave the variations among the genotypes, treatments and their interactions. The present study showed that Mundan, Odiyan, Muttadan, Kallimadiyan and Vellimuthu had less percentage reduction in growth parameters at the germination stage. Odiyan and Mundan showed less percentage reduction in fresh weight (36.09%) and shoot length (25.61%) respectively, in relative water content (10.70% and 16.07%, respectively) at higher concentrations of salinity (150mM) compared to control. Pokali, Chembakam and Odiyan showed good germination parameters under three different saline treatments compared to other genotypes. Biplot analysis showed 65.4% variation between the treatments, whereas the variation between the genotypes was around 13.3%. Screening of landraces for salinity tolerance at the seed germination stage is the most reliable method to identify the salt tolerant line at the early seedling stage. The present study can be used for further screening programme at the vegetative stage for the identification of potential salt tolerant lines to improve breeding and gene introgression studies.
LIDERANÇA, BEM-ESTAR NO TRABALHO E O DARK TRIAD: ANÁLISE DA PERCEPÇÃO DE COLABORADORES BRASILEIROS

O estudo objetiva a análise da influência dos traços de personalidade do Dark Triad em líderes sobre o bem-estar no trabalho de colaboradores. Para tanto, foi aplicado um survey com 268 colaboradores brasileiros. A estatística descritiva, o teste de hipóteses, as regressões múltipla e logística foram aplicadas. Os resultados evidenciaram que os colaboradores percebem seus líderes com traços narcisistas. Quanto ao bem-estar no trabalho, os colaboradores exibiram maior sentimento de realização no trabalho. As dimensões do bem-estar relativas aos afetivos positivos, negativos e de realização, mostraram-se diferentes na presença de líderes com traços maquiavélicos e psicopáticos. Os três traços associaram-se positivamente às emoções e aos humores negativos no ambiente laboral e negativamente aos afetos positivos e de realização no trabalho. Quanto mais fortes os traços maquiavélicos, maior a propensão para afetos negativos e menor propensão para afetos positivos e de realização. Os resultados oportunizam a reflexão sobre as ações de líderes com traços elevados da tríade sombria que interferem nos sentimentos e emoções positivas e impactam nas perspectivas de realização profissional dos colaboradores. Suscita o debate sobre os desdobramentos comportamentais de líderes ricos desses traços no ambiente laboral no período de crise pandêmica, haja vista o impacto direto na produtividade organizacional e saúde mental dos colaboradores. Ademais, implicam um olhar mais cuidadoso nos ambientes educacionais e programas de desenvolvimento de competências em liderança, com vistas a promover a empatia, busca de altruísmo e de valores de orientação para a vida, que considerem a valorização dos grupos e o bem-estar geral.
A New Slab Model Approach for Electronic Structure Calculation of Polar Semiconductor Surface

A new slab model approach is examined for the electronic structure calculation of a polar semiconductor surface. Our proposed slab model contains fractionally charged H atoms which completely terminate a noninteresting surface of the slab. We have studied in detail the electronic structure of the polar GaAs(001) surface in order to examine the reliability of our slab model. Calculation is performed by the ab initio pseudopotential method. We have found that our slab model can accurately describe a polar semiconductor surface. In addition, this model can greatly reduce the computational time.
Multidimensional modal analysis of nonlinear sloshing in a rectangular tank with finite water depth

The discrete infinite-dimensional modal system describing nonlinear sloshing of an incompressible fluid with irrotational flow partially occupying a tank performing an arbitrary three-dimensional motion is derived in general form. The tank has vertical walls near the free surface and overturning waves are excluded. The derivation is based on the Bateman–Luke variational principle. The free surface motion and velocity potential are expanded in generalized Fourier series. The derived infinite-dimensional modal system couples generalized time-dependent coordinates of free surface elevation and the velocity potential. The procedure is not restricted by any order of smallness. The general multidimensional structure of the equations is approximated to analyse sloshing in a rectangular tank with finite water depth. The amplitude–frequency response is consistent with the fifth-order steady-state solutions by Waterhouse (1994). The theory is validated by new experimental results. It is shown that transients and associated nonlinear beating are important. An initial variation of excitation periods is more important than initial conditions. The theory is invalid when either the water depth is small or water impacts heavily on the tank ceiling. Alternative expressions for hydrodynamic loads are presented. The procedure facilitates simulations of a coupled vehicle–fluid system.
