Authors: Rath B. , Kumar K. S. , Krishna D. V. 
Published: September 2023

Invesigation of bounds for Hankel determinat of analytic univalent functions is prominent intrest of many researcher from early twenth century to study geometric properties. Many authors obtained non sharp upper bound of third Hankel determinat for different subclasses of analytic univalent functions until Kwon et al. obtained exact estimation of the fourth coefficeient of Caratheodory class. Recently authors made use of an exact estimation of the fourth coefficient, well known second and third coefficient of Caratheodory class obtained sharp bound for the third Hankel determinant associated with subclasses of analytic univalent functions. Let $w=f(z)=z+a_{2}z^{2}+\cdots$ be analytic in the unit disk $\mathbb{D}=\{z\in\mathbb{C}:|z|<1\}$, and $\mathcal{S}$ be the subclass of normalized univalent functions with $f(0)=0$, and $f'(0)=1$. Let $z=f^{-1}$ be the inverse function of $f$, given by $f^{-1}(w)=w+t_2w^2+\cdots$ for some $|w|<r_o(f)$. Let $\mathcal{S}^c\subset\mathcal{S}$ be the subset of convex functions in $\mathbb{D}$. In this paper, we estimate the best possible upper bound for the third Hankel determinant for the inverse function $z=f^{-1}$ when $f\in \mathcal{S}^c$.Let $\mathcal{S}^c$ be the class of convex functions. We prove the following statements (Theorem):If $f\in$ $\mathcal{S}^c$, then\begin{equation*}\big|H_{3,1}(f^{-1})\big| \leq \frac{1}{36}\end{equation*} and the inequality is attained for $p_0(z)=(1+z^3)/(1-z^3).$
Transformation operators for impedance Sturm–Liouville operators on the line
Authors: Kazanivskiy M. , Mykytyuk Ya. , Sushchyk N. 
Published: September 2023

In the Hilbert space $H:=L_2(\mathbb{R})$, we consider the impedance Sturm--Liouville operator $T:H\to H$ generated by the differential expression $ -p\frac{d}{dx}{\frac1{p^2}}\frac{d}{dx}p$, where the function $p:\mathbb{R}\to\mathbb{R}_+$ is of bounded variation on $\mathbb{R}$ and $\inf_{x\in\mathbb{R}} p(x)>0$. Existence of the transformation operator for the operator $T$ and its properties are studied.
In the paper, we suggest an efficient parametrization of the impedance function p in term of a real-valued bounded measure $\mu\in \boldsymbol M$ via$p_\mu(x):= e^{\mu([x,\infty))}, x\in\mathbb{R}.$For a measure $\mu\in \boldsymbol M$, we establish existence of the transformation operator for the Sturm--Liouville operator $T_\mu$, which is constructed with the function $p_\mu$. Continuous dependence of the operator $T_\mu$ on $\mu$ is also proved. As a consequence, we deduce that the operator $T_\mu$ is unitarily equivalent to the operator $T_0:=-d^2/dx^2$.

Published: September 2023

Purpose: Evaluate the feasibility of transcranial direct current stimulation (tDCS) as an adjunct to inpatient physiotherapy for children and youth with acquired brain injury (ABI). Method: This randomized feasibility trial allocated children (5–18 years of age with moderate to severe ABI) to receive either active or sham anodal tDCS immediately prior to 16 of their existing inpatient physiotherapy sessions. Participants, physiotherapists, assessors, and primary investigators were blinded to treatment allocation. Eligibility, recruitment, retention, tolerance, and preliminary treatment outcomes were evaluated against a priori feasibility targets. Results: Of 232 children admitted over 21 months, six were eligible (2.6%) and four were recruited (66.7%). One participant completed the entire study protocol, two were withdrawn for unrelated changes in medical stability, and one could not commence the study due to COVID-19 restrictions. Participants completed all tDCS sessions that were started with the primary transient side effect being sub-electrode itchiness. Conclusions: While the study was infeasible from eligibility and retention perspectives, study procedures (e.g., assessment, treatment, side effect tracking, physiotherapy documentation) were viable and should be applied to future paediatric tDCS studies.

Lactobacillus rhamnosus are Gram-positive and lactic acid-producing bacteria. Meanwhile, Candida albicans and Candida tropicalis are opportunistic fungi that cause oral candidiasis. This study aimed to determine the effect of LGG on the biofilm formation of C. tropicalis and C. albicans with the hypothesis that LGG inhibits the biofilm of the yeasts. C. albicans ATCC MYA-4901 and C. tropicalis ATCC 13803 were standardised to 1x106 cells to form a mono-species biofilm. L. rhamnosus GG (LGG) was standardised to 1x107 cells, equivalent to absorbance 0.5 at OD620nm. The microorganisms were cultivated in nutrient broth in a 96-well plate and incubated at 37°C for 24 h and 48 h. Co-culture biofilm was developed by combining Candida spp. with LGG in the same well at a similar concentration as the mono-culture. Crystal violet assay was conducted to assess the biofilm biomass with absorbance measured at OD620nm wavelength. After 24 hours, polymicrobial biofilms of C. albicans with LGG decreased by 37.1 ± 9.2%. At 48 hours, it further decreased to 44.7 ± 5.9%. For C. tropicalis, co-culture biofilms with LGG decreased by 16.3 ± 5.9% and 35.7 ± 7.6% after 24 h and 48 h incubation, respectively. LGG significantly reduced C. albicans biofilm compared to C. tropicalis (P<0.05). In conclusion, LGG has antibiofilm activity against C. albicans and C. tropicalis. However, further study is needed to conclude the effect against other species strains.

Does the Immigration Issue Divide German Attitudes toward Social Welfare?
Authors: Häkkilä Laura , Pfeifer Michael , Toikko Timo 
Published: September 2023

Abstract
This article explores the association of German attitudes toward social welfare and immigration, and how regional and political factors affect that relationship. The data was retrieved from Round 8 of the European Social Survey, which includes 2,852 German participants. Quantitative methodology was used to study the hypotheses. Analyses demonstrate that attitudes on immigration and social welfare are associated. However, the regional factor of Eastern and Western Germany and political self-placement shape the population concerning the relationship between social welfare and immigration. The immigration issue diverges the views of both the leftists and Western Germans to social welfare more than the rightists and Eastern Germans. In this respect, the immigration issue shapes the view of the German welfare state.
“Make a Living by Doing Good”
Authors: Li Yong 
Published: September 2023

Abstract
This article focuses on the e-commerce of infant milk by Chinese migrant women in France, who became retail agents for their Chinese clients after the melamine infant formula scandal in China in 2008. The daigou-ers conceive of their WeChat business as an activity of solidarity, one that allows them to earn a living while helping Chinese parents get safe baby foods. My article proposes to conceptualize the daigou business of formula milk as a moral economy and analyze the ways in which online and offline realities merge and collide in the making of this moral economy. I argue that the moral economy of infant formulas is co-constructed by the virtual encounters between the seller and the buyer, the materiality and mobility of infant milk, the dynamics of the infrastructures of mobility, the offline hazards and challenges affecting the supply and transportation of the formula milk, and customers’ risk perception.
How Far Can Chicken Feet Travel?
Authors: Zani Beatrice , Cockel Isabelle 
Published: September 2023

Abstract
This article analyses Chinese women's e-entrepreneurship of trading nostalgic and/or contested goods in the disputed sovereign borders and virtual marketplace in the borderland between China and Taiwan. Using physical and digital ethnography, and drawing on the case study of the journey of chicken feet and other goods traded through WeChat by Chinese women in Taiwan, this article shows how the online and offline trails of these goods and the virtual marketplace generate new forms of transnationalism and connectedness between the two rivaling societies. Calling attention to Chinese women's emotions and nostalgia embedded in their e-entrepreneurship, their goods’ geographical movements, and their social networks, these findings enrich our understanding of transnational entrepreneurship as well as migrants’ agency-making and digital connectivity. However, highlighting how the worsening Taiwan-China relationship has diminished micro e-entrepreneurship, this article also reveals the vulnerability, instability, and uncertainty of the virtual marketplace, which is threatened by the politics of sovereignty contestation.
