The purpose of this study is to compare and contrast eastern and western perspectives on work-life balance (WLB). The study is based on (1) literature review; (2) secondary data on working hours and ...parental leave in different countries; (3) WLB policies and practices of 25 large firms of both western and eastern origins (from their respective websites); (4) WLB ratings across companies (glassdoor.com) and (5) informal semi-structured interviews with HR heads from 50 multinational companies and 50 Indian companies, in both the private and the public sectors, on family-friendly workplaces. Qualitative analysis revealed that in Asian countries gender socialization played a major role in one's perception towards WLB, and coping strategies were also individual driven. While American multinationals focused on flexible working practices, the focus for Indian companies was on employee welfare programmes. On the basis of data provided by glassdoor.com, which compares WLB across companies, it is noted that the American and European companies rank higher than the Indian companies as they pay a lot more attention to it. The study also looks at government policies on working hours and parental leave and concludes that western countries have fewer working hours and more generous parental leave, as compared to their counterparts in Asia.
In patients with ischemic stroke and a proximal cerebral arterial occlusion and salvageable tissue on imaging, alteplase followed by thrombectomy with a stent retriever was more effective than ...alteplase alone in improving reperfusion, neurologic recovery, and functional outcome.

Objective
This study examines thematic content and discourse surrounding multiracial socialization between Black and non‐Black multiracial families on multiracial mommy blogs.
Background
Mommy blogs ...have been recognized as a medium through which mothers challenge dominant representations of motherhood, create community with other mothers, and seek out advice. But little is known about how mothers write about and discuss race, racism, and multiracial socialization online. This study addresses this knowledge gap by analyzing how a niche of bloggers—mothers to multiracial children—construct narratives surrounding race, multiraciality, and multiracial socialization online and how their narratives differ by the racial makeup of the blogger's family.
Method
Using a MultiCrit framework, this study analyzes 13 mommy blogs written by mothers of color with multiracial children. Blogs were analyzed for thematic content related to race, racial identification, multiraciality, and multiracial socialization.
Results
The findings demonstrate that mothers' orientations to multiracial socialization vary depending on whether the blogger has Black or non‐Black multiracial children. Bloggers who are mothers to Black multiracial children blogged frequently about their engagement in safety socialization, whereas mothers with non‐Black multiracial children did not.
Conclusion
The stark difference between thematic content from bloggers with and without Black multiracial children highlights the differing experiences among Black and non‐Black multiracial people, for mothers of Black multiracial children, and the implications anti‐Black racism has on family processes.

Machine learning (ML) is a burgeoning field of medicine with huge resources being applied to fuse computer science and statistics to medical problems. Proponents of ML extol its ability to deal with ...large, complex and disparate data, often found within medicine and feel that ML is the future for biomedical research, personalized medicine, computer‐aided diagnosis to significantly advance global health care. However, the concepts of ML are unfamiliar to many medical professionals and there is untapped potential in the use of ML as a research tool. In this article, we provide an overview of the theory behind ML, explore the common ML algorithms used in medicine including their pitfalls and discuss the potential future of ML in medicine.
Raindrop size distribution (DSD) information is fundamental in understanding the precipitation microphysics and quantitative precipitation estimation, especially in complex terrain or urban ...environments which are known for complicated rainfall mechanism and high spatial and temporal variability. In this study, the DSD characteristics of rainy seasons in the Beijing urban area are extensively investigated using 5-year DSD observations from a Parsivel2 disdrometer located at Tsinghua University. The results show that the DSD samples with rain rate < 1 mm h−1 account for more than half of total observations. The mean values of the normalized intercept parameter (log 10Nw) and the mass-weighted mean diameter (Dm) of convective rain are higher than that of stratiform rain, and there is a clear boundary between the two types of rain in terms of the scattergram of log 10Nw versus Dm. The convective rain in Beijing is neither continental nor maritime, owing to the particular location and local topography. As the rainfall intensity increases, the DSD spectra become higher and wider, but they still have peaks around diameter D∼0.5 mm. The midsize drops contribute most towards accumulated rainwater. The Dm and log 10Nw values exhibit a diurnal cycle and an annual cycle. In addition, at the stage characterized by an abrupt rise of urban heat island (UHI) intensity as well as the stage of strong UHI intensity during the day, DSD shows higher Dm values and lower log 10Nw values. The localized radar reflectivity (Z) and rain rate (R) relations (Z=aRb) show substantial differences compared to the commonly used NEXRAD relationships, and the polarimetric radar algorithms R(Kdp), R(Kdp, ZDR), and R(ZH, ZDR) show greater potential for rainfall estimation.

approach for turbulent modeling were involved. Contours are presented for different inlet velocity and pitch ratio. Results indicated that the lower the pitch ratio, the better is the temperature gradient. Nanofluid transfers more heat with decline of pitch ratio because of lower generation of longitudinal disturbance. As inlet velocity augments and pitch ratio decreases, nanofluid can scour the wall more easily and heat transfer rate is strengthened.
The pyrochlore lattice is a versatile venue to probe the properties of magnetically ordered states induced or perturbed by anisotropic terms like the Dzyaloshinskii-Moriya interactions or single-ion ...anisotropy. Several such ordered states have been investigated recently as precursors of topological magnons and the associated surface states. In parallel, there has been recent progress in growing thin films of magnetic materials with this lattice structure along high symmetry directions of the lattice. In both cases, an account of the magnetic excitations of relevant Hamiltonians for finite slabs is a necessary step in the analysis of the physics of these systems. While the analysis of bulk magnons for these systems is quite common, a direct evaluation of the magnon spectra in the slab geometry, though required, is less frequently encountered. We study here magnon bands in the slab geometry for a class of spin models on the pyrochlore lattice with Heisenberg exchange, Dzyaloshinskii-Moriya interaction and spin-ice anisotropy. For a range of model parameters, for both ferromagnetic and antiferromagnetic exchange, we compute the classical ground states for different slab orientations and determine the spin wave excitations above them. We analyze the ferromagnetic splay phase, the all-in-all-out (AIAO) phase and a coplanar phase and evaluate magnon dispersions for slabs oriented perpendicular to the 111, 100 and 110 directions. For all the phases considered, depending on the slab orientation, magnon band structures can be non-reciprocal and we highlight the differences in the three orientations from this point-of-view. Finally, we present details of the surface localized magnons for all the three slab orientations in the phases we study. For the ferromagnetic splay phase and the AIAO phase we analyze surface states associated with point degeneracies or nodal lines in the bulk spectrum by computing the magnonic Berry curvature and Weyl charges or Chern numbers associated with it.
Nanosize hydroxyapatite (nHAp) doped with varying levels of Fe3+ (Fe-nHAp of average size 75 nm) was synthesized by hydrothermal and microwave techniques. The samples were characterized for ...physiochemical properties by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), inductively coupled plasma optical emission spectrometer (ICP-OES), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), mechanical and dielectric properties. The biological properties like hemocompatibility, antibacterial efficacy, in vitro bioactivity and the cell proliferation of the samples were determined. XRD pattern of the samples were of single phase hydroxyapatite. As the content of Fe3+ increased, the crystallite size as well as crystallinity decreased along with a morphological change from spherulites to rods. The dielectric constants and Vickers hardness were enhanced on Fe3+ doping. The VSM studies revealed that the saturation magnetization (M s) and retentivity (M r) were found to increase for Fe-nHAp. nHAp impregnated with an antibiotic as a new system for drug delivery in the treatment of chronic osteomyelitis was also attempted. The in vitro drug release with an antibiotic amoxicillin and anticancer drug 5-fluorouracil showed sustained release for the lowest concentration of Fe3+, while with an increase in the content; there was a rapid release of the drug. The hemolytic assay of Fe3+ doped samples revealed high blood compatibility (<5% hemolysis). The antibacterial activities of the antibiotic impregnated materials were tested against a culture of E. coli, S. epidermidis and S. aureus by agar diffusion test. The in vitro bioactivity test using simulated body fluid (SBF) showed better bone bonding ability by the formation of an apatite layer on the doped samples. The growth of the apatite layer on the samples surface has been confirmed by EDS analysis. The proliferative potential of MG63 cells by MTT assay confirmed the noncytotoxicity of the samples.
