Abstract

Background
This study was designed to examine the effectiveness of program combining chakrayoga and meditation on the physical health and disease-related factors and psychological factors of people.

Methods
Ninety-seven subjects (32–83 years old) who had free from prior experiences in meditation programs or Chakrayoga training courses were assigned to either the experimental group (EXP) (45 subjects; 13 male subjects and 32 female subjects; average age of 60.67 years, SD=11.09 years) or the control group (CONT) of remaining subjects (52 subjects; 14 male subjects and 38 female subjects; average age of 61.58 years, SD=9.70 years). Subjects in the EXP participated in the Chakrayoga Meditation Program for twice a week for 2 h during 6 weeks in each session consisted of 1 h of Chakrayoga and 1 h of meditation. The measurements in this study included the mindfulness, stress response, subjective quality of life, medical symptom checklist, difficulty in emotional regulation and objective of life and sense of control.

Results
Results revealed that participants in the EXP reported significantly more relief of mindfulness, stress response, subjective quality of life and medical symptom checklist than those in the CONT.

Conclusions
These findings provide evidence that the Chakrayoga Meditation Program can help relieve the physical health and disease-related factors and psychological factors.

Authors: Wang Yan , Han Shangya , Qin Panke , Li Yaping , Shen Yanmei 
Published: December 2019

Abstract
For the effective bearer of P2P-type services, a P2P service bearer reorientation method for passive optical network for long-distance wide access based on P2P protocol message and wire-speed message identification is proposed. However, the reorientation method still has the possibility of relocation failure, so it is modified – that is, an improved P2P service bearer reorientation method based on optical line terminal (OLT) and optical network unit (ONU) cooperation. And the tool NS2 is used for network simulation analysis. Through simulation analysis, it is verified that the modified reorientation method improves the data traffic burden at the core network and at the OLT.

Abstract
Let 𝓞𝕂 be the ring of integers of the number field 𝕂 =
$\begin{array}{}
\displaystyle
\mathbb{Q}(\sqrt{2},\sqrt{3})
\end{array}$. A D(n)-quadruple in the ring 𝓞𝕂 is a set of four distinct non-zero elements {z1, z2, z3, z4} ⊂ 𝓞𝕂 with the property that the product of each two distinct elements increased by n is a perfect square in 𝓞𝕂. We show that the set of all n ∈ 𝓞𝕂 such that a D(n)-quadruple in 𝓞𝕂 exists coincides with the set of all integers in 𝕂 that can be represented as a difference of two squares of integers in 𝕂.
Geometry of ℙ2 blown up at seven points
Authors: Ray Nabanita 
Published: December 2019

Abstract
In this paper, we prove that blown up at seven general points admits a conic bundle structure over ℙ1 and it can be embedded as (2, 2) divisor in ℙ1 × ℙ2. Conversely, any smooth surface in the complete linear system |(2, 2)| of ℙ1 × ℙ2 can be obtained as an embedding of blowing up ℙ2 at seven points. We also show that smooth surface linearly equivalent to (2, 2) in ℙ1 × ℙ2 has at most four (−2) curves.

Published: December 2019

Abstract
Yuqun Chen and K. P. Shum in [Rees short exact sequence of S-systems, Semigroup Forum 65 (2002), 141–148] introduced Rees short exact sequence of acts and considered conditions under which a Rees short exact sequence of acts is left and right split, respectively. To our knowledge, conditions under which the induced sequences by functors Hom(RLS, –), Hom(–, RLS) and AS ⊗ S– (where R, S are monoids) are exact, are unknown. This article addresses these conditions. Results are different from that of modules.

AbstractLet 𝓐 denote the family of analytic functionsfwithf(0) =f′(0) – 1 = 0, in the open unit disk Δ. We consider a class$$\begin{array}{} \displaystyle \mathcal{S}^{\ast}_{cs}(\alpha):=\left\{f\in\mathcal{A} : \left(\frac{zf'(z)}{f(z)}-1\right)\prec \frac{z}{1+\left(\alpha-1\right) z-\alpha z^2}, \,\, z\in \Delta\right\}, \end{array}$$where 0 ≤α≤ 1/2, and ≺ is the subordination relation. The methods and techniques of geometric function theory are used to get characteristics of the functions in this class. Further, the sharp inequality for the logarithmic coefficientsγnoff∈$\begin{array}{} \mathcal{S}^{\ast}_{cs} \end{array}$(α):$$\begin{array}{} \displaystyle \sum_{n=1}^{\infty}\left|\gamma_n\right|^2 \leq \frac{1}{4\left(1+\alpha\right)^2}\left(\frac{\pi^2}{6}-2 \mathrm{Li}_2\left(-\alpha\right)+ \mathrm{Li}_2\left(\alpha^2\right)\right), \end{array}$$where Li2denotes the dilogarithm function are investigated.

Weakly demicompact linear operators and axiomatic measures of weak noncompactness
Authors: Krichen Bilel , O’Regan Donal 
Published: December 2019

Abstract
In this paper, we study the relationship between the class of weakly demicompact linear operators, introduced in [KRICHEN, B.—O’REGAN, D.: On the class of relatively weakly demicompact nonlinear operators, Fixed Point Theory 19 (2018), 625–630], and measures of weak noncompactness of linear operators with respect to an axiomatic one. Moreover, some Fredholm and perturbation results involving the class of weakly demicompact linear operators are investigated. Our results are then used to investigate the relationship between the relative essential spectrum of the sum of two linear operators and the relative essential spectrum of each of these operators.

In this paper, we consider F𝓡-generalized contractivity condition and utilized the same to establish some fixed point results for a self-mapping in partial metric spaces endowed with an amorphous binary relation. Our results generalize several core results of the existing literature. We also furnish some examples to exhibit the utility of our results. Finally, we further deduce fixed point result for cyclic contractions in partial metric spaces.

Authors: Chen Xiaomin 
Published: December 2019

AbstractIn this article we study Einstein-Weyl structures on a 3-dimensional trans-Sasakian manifoldMof type (α,β). First, we prove that a 3-dimensional trans-Sasakian manifold admitting both Einstein-Weyl structuresW±= (g, ±θ) is Einstein, or is homothetic to a Sasakian manifold ifα≠ 0. Next forβ≠ 0 it is proved thatMis Einstein, or is homothetic to anf-Kenmotsu manifold if it admits an Einstein-Weyl structureW= (g,κη) for some nonzero constantκ. Finally, a classification is obtained when a trans-Sasakian manifold admits a closed Einstein-Weyl structure. Further, ifMis compact we also obtain two corollaries.
∗-Ricci solitons and gradient almost ∗-Ricci solitons on Kenmotsu manifolds
Authors: Venkatesha  , Naik Devaraja Mallesha , Kumara H. Aruna 
Published: December 2019

Abstract
In this paper, we consider *-Ricci soliton in the frame-work of Kenmotsu manifolds. First, we prove that if (M, g) is a Kenmotsu manifold and g is a *-Ricci soliton, then soliton constant λ is zero. For 3-dimensional case, if M admits a *-Ricci soliton, then we show that M is of constant sectional curvature –1. Next, we show that if M admits a *-Ricci soliton whose potential vector field is collinear with the characteristic vector field ξ, then M is Einstein and soliton vector field is equal to ξ. Finally, we prove that if g is a gradient almost *-Ricci soliton, then either M is Einstein or the potential vector field is collinear with the characteristic vector field on an open set of M. We verify our result by constructing examples for both *-Ricci soliton and gradient almost *-Ricci soliton.

Abstract
In this paper, we consider the wavelet estimators of a nonparametric regression model based on widely orthant dependent random errors. The moment consistency and the completely consistency for wavelet estimators under some more mild moment conditions are investigated. The results obtained in the paper improve and extend the corresponding ones for dependent random variables. Finally, we provide a numerical simulation to verify the validity of our results.

Authors: Yu Yuncai , Liu Xinsheng , Liu Ling , Liu Weisi 
Published: December 2019

Abstract
This paper considers the nonparametric regression model with negatively super-additive dependent (NSD) noise and investigates the convergence rates of thresholding estimators. It is shown that the term-by-term thresholding estimator achieves nearly optimal and the block thresholding estimator attains optimal (or nearly optimal) convergence rates over Besov spaces. Additionally, some numerical simulations are implemented to substantiate the validity and adaptivity of the thresholding estimators with the presence of NSD noise.

Published: December 2019

Abstract
This paper is a continuation of [Bisht, R. K.—Rakočević, V.: Generalized Meir-Keeler type contractions and discontinuity at fixed point, Fixed Point Theory 19(1) (2018), 57–64]. We obtain some fixed point theorems under contractive conditions which admit discontinuity at the fixed point. Our results subsume all the known results of similar type, provide new answers to the question of continuity of contractive mappings at their fixed points, and also rectify some recent results by Bisht and Rakočević. Many examples are given to illustrate our results.

A model of an action of the amperometric biosensors based on carbon paste electrodes encrusted with single microreactor is analyzed. The model is based on non stationary diffusion equations containing non-linear term related to the enzymatic reaction. The biosensors current, which is a function of the concentration gradient of the reaction product on the electrodes, is used for analyzing of dynamics of the reaction. An influence of a size of microreactor, a geometrical form of microreactor and a position of microreactor on the biosensors action is investigated.

Published: December 2019

Abstract: Introduction: During kayaking, the whole body works in a perfect harmony. While the trunk is doing a rotation, flexion-extension helps to the upper limb to create a special cyclic paddle. The purpose of this study was to gain a better understanding of the physical disabled (later disabled) person’s kayaking motions and to probe whether there were any significant differences between disabled and non-disabled kayakers with special focus on the use of footrest. We hypothesised significantly different ranges of motion and muscle activity in lower limbs but no significant differences in those of the upper limbs. Aim: Our goal was to know more about the abled and disbled kayaking and compare the athlete’s kayaking movements. Method: Thirteen (n = 13) elite disabled athletes (age range: 18–40 years, height range: 164–194 cm, body mass range:74–93 kg), eleven (n = 11) elite non-disabled athletes (age range: 18–40 years, height range:172–197 cm, body mass range: 72–96 kg) and nine (n = 9) athletes whose movements were artificially limited to imitate disabled conditions(“imitation disabled” group) (age range: 18–40 years, height range: 172–197 cm, body mass range: 72–96 kg) were measured. Weba sport kayak ergometer, surface electromyography (EMG), and a 3-dimensional Vicon (MX T40) camera system were used to record the data, and a combined Matlab and MS Excel system was used to analyse the results. Results: In line with our basic assumption, range of motion of the upper limbs was not significantly different between disabled athletes and non-disabled athletes (p ≥ 0.05). However, muscle activities were significantly different in the disabled group compared to the non-disabled group (p ≤ 0.05). In the disabled group the knee joint and trunk motions and muscle activities were also significantly different compared to those in the non-disabled group (p ≤ 0.05). The differences in performance force applied to both footrests and force were significant (p ≤ 0.05). Discussion: The assumption that shoulder and elbow ranges of motion were not significantly different in disabled athletes compared to non-disabled athletes was proven. However, muscle activities were significantly different in the disabled group. In the disabled group, knee and trunk motions and muscle activities were also significantly different compared to the non-disabled group. Significant differences were found in performance, force and footrest use. Our results proved our assumption that motions and muscle activities of disabled and non-disabled athletes were significantly different. Orv Hetil. 2019; 160(52): 2061–2066.

Published: December 2019

Abstract: Introduction: Due to the increasing number of arthroplasties, the number of post-operative hospital days was reduced and the rate of rehabilitation accelerated. For this, proper postoperative analgesia is essential and the multimodal pain relief is an excellent tool. Aim: The aim of our study was to compare postoperative functional results, postoperative pain levels, and opioid analgesic needs of patients who received conventional and novel analgesic treatments. Method: In our prospective study, 81 patients were enrolled who underwent primary hip prosthesis surgery in our institution between February 2017 and January 2018. Of the randomized patients, 38 were in the control group and 43 in the multimodal pain group. We have tested their analgesic needs and the subjective pain levels of patients with the help of the visual analog scale (VAS). Results: Patients receiving multimodal pain relief had significantly lower opioid analgesic requirements and significantly lower VAS values assessed at 6 hours, and 3 and 4 days postoperatively. In addition, the patients in this group stayed in the hospital for a significantly shorter time after surgery. Conclusions: Based on our experience, multimodal pain relief in one-sided primary hip joint arthroplasty significantly reduced the patients’ postoperative subjective pain sensation and pain killer consumptions.

Abstract: The authors present a case report of a patient who was treated conservatively for a non-specific headache for more than a decade, while an arachnoidal cyst in the middle cranial fossa, over the temporal bone tegmen was diagnosed, but ruled out as the cause of the headache. The patient was referred to our ENT department with left, purulent ear discharge. Besides a chronic purulent otitis media, a cholesterol granuloma occupying the antrum, eroding the tegmen of the pyramid bone and penetrating into the middle cranial fossa was diagnosed. Case presentation of a patient with cholesterol granuloma, surgical options, differential diagnostic problems, and a literature review are presented. Tympanoplasty with cortical mastoidectomy was carried out to treat the chronic purulent otitis media, and the cholesterol granuloma was removed during transmastoid craniotomy. The iatrogenic temporal meningo-encephalic tissue herniation was repaired and the bone defect of the tegmen was reconstructed with septal cartilage. The patient’s headache diminished immediately after the surgery. The chronic ear discharge stopped, the cholesterol granuloma was excised completely and the cerebral herniation was repaired successfully. Neither CSF leak, nor further herniation or meningitis were noticed. Two years after the operation the patient is asymptomatic. A large cholesterol granuloma, eroding into the middle cranial fossa can cause serious complications, and needs a high level of attention besides individualized surgical treatment based on the surgeon’s abilities and skills.

Abstract: Introduction: The harmful effects represent an important public health problem in tha world. Aim: Our aim is to report and compare the results of screenings performed in Hungary’s Comprehensive Health Screening Program 2010–2020–2030 (MÁESZ) with international data. Method: During the 9-year continuous screening, we analyzed the data of 71 922 women and 60 934 men in the 18–80-year-old population and examined the occurrence of regular daily smokers. Data were collected with the help of special screening data sheets. Results: 24.4% of males and 24.2% of females smoked regularly during the 9-year screening period. Between 2012 and 2015, smoking prevalence showed a temporary significant decline, then, from 2016, it started to increase again. The downturn coincided with the opening of national tobacco stores. In men, the proportion of smokers was significantly higher in young adults (18–25 years) than in women. Later in life, the difference leveled off and even between 46–55 years, the prevalence of smoking was greater in women. There is a difference in smoking patterns between the two genders, which is probably related to marriage and motherhood in women. After 56 years, the proportion of smokers in both genders decreased rapidly. The prevalence of smoking in Hungary in all age groups significantly exceeds the European and world average. Transient increases in middle-aged women have also been reported in European surveys. Conclusion: Compared to 2010, the proportion of smokers has decreased in Hungary, but a new surge observed after 2015 is not a positive phenomenon. We find the high proportion of smoking women worrying. Orv Hetil. 2019; 160(52): 2047–2053.
Elizabeth Anscombe and an argument against contraception
Authors: Mccarthy Anthony 
Published: December 2019

In the 1960s, before the promulgation of Humanae Vitae, the Catholic philosophers Elizabeth Anscombe and Herbert McCabe OP debated whether there are convincing natural law arguments for the claim that contraception violates an exceptionless moral norm. This article revisits those arguments and critiques McCabe’s approach to natural law, concerned primarily with ‘social sin’ and not simply violations of ‘right reason,’ as one particularly ill-suited to addressing questions in sexual ethics and unable both to distinguish properly between certain forms of sexual wrongdoing and more obviously social sins such as theft, and also to distinguish between ‘natural’ and ‘unnatural’ sexual acts. Anscombe’s views, I argue, are closer to those of Thomas Aquinas and provide reasons for making the distinctions McCabe does not. An argument concerning the nature of the institution of marriage and the effects of non-marital acts on that institution is proposed as a way of strengthening Anscombe’s argument that contraception violates an exceptionless moral norm.

Published: December 2019

W artykule została zastosowana metoda analizy etycznej w celu przedstawienia znaczenia fenomenu uczciwości na przykładzie powieści Fiodora Dostojewskiego Bracia Karamazow. Etyka nikomachejska oraz Etyka wielka Arystotelesa zostały wykorzystane do dokonania oceny etycznej bohaterów powieści i ich działań. Ranga poruszanych przez pisarza problemów umożliwia interpretację dzieła jako powieści – tragedii. W ostatniej części artykułu została przedstawiona charakterystyka jednego z tytułowych bohaterów powieści, Dymitra, z uwzględnieniem cech umożliwiających uznanie go za bohatera tragedii, którego czyny nie wynikają z nikczemności i podłości, ale z powodu „zbłądzenia”. Celem artykułu jest ukazanie analizy etycznej dzieł literackich jako sposobu ­interpretowania i odbioru samego dzieła przez pryzmat ukazanych w nim wartości.
