EXTENSIONS OF THE SCHWARZ PROBLEM FOR THE BELTRAMI OPERATOR IN THE HALF UNIT DISC
No full textIn this study, we investigate the Schwarz problem for the Beltrami operator in the upper half of the unit disc in the complex plane. We derive the solution to this boundary value problem and establish the necessary conditions for solvability. Furthermore, we extend our analysis to a second-order equation, providing a comprehensive treatment of the Schwarz problem for higher-order cases. The results presented in this paper contribute to the understanding of boundary value problems associated with the Beltrami operator and their generalizations, offering new insights and potential applications in complex analysis and related fields. © 2025 Elsevier B.V., All rights reserved
The Effect of White Noise and Recorded Lullaby during Breastfeeding on Newborn Stress, Mother's Breastfeeding Success, and Comfort: A Randomized Controlled Trial
No full textPurpose: The study was aimed at determining the effect of exposure to white noise and recorded lullaby during breastfeeding on newborn stress, mother's breastfeeding success, and comfort. Design and methods: This single-blinded and three-parallel group randomized controlled study consisted of mothers who had given birth and whose newborns were at a hospital in Turkey. Seventy-five participants completed the study. They were assigned to white noise, lullaby, and control groups in equal numbers. Each group included 25 women. The questionnaires included descriptive characteristics of mothers, the LATCH Breastfeeding Assessment Tool, the Newborn Stress Scale, and the Visual Analog Scale. During the breastfeeding process, the newborn and mother listened to white noise and lullaby for approximately 15 min. The newborn stress and mothers' level of comfort were assessed before and after the interventions. The breastfeeding success of the mother assessed with the LATCH was completed within the first 15 min of breastfeeding. Results: The mean scores obtained from the Newborn Stress Scale by the mothers in the lullaby group and white noise group decreased significantly after the intervention. A significant difference was also observed in the control group. There were also significant differences between the changes in the mothers' comfort level of all groups. There were significant differences between the changes in the LATCH scores of the groups. Conclusion: Both white noise and recorded lullaby significantly reduced newborn stress, and increased mother's comfort in the early postpartum period. Practice implications: Music should be used as a nonpharmacological method to improve breastfeeding success in newborns. © 2025 Elsevier B.V., All rights reserved.(06.09.2023, 1168/1148
Clinical Outcomes of Patients Undergoing Isolated and Combined Subscapularis Repair
No full textBackground: Subscapularis (SSC) tears can present as isolated or combined with additional rotator cuff tendon tears. The repair of SSC tear improves postoperative outcomes. However, the effect that SSC repair and healing have on functional outcomes after arthroscopic repair of isolated or combined SSC tears requires further investigation. Purpose: To (1) compare the clinical outcomes of arthroscopic rotator cuff repair (ARCR) of isolated SSC tears with those having SSC tears combined with supraspinatus and/or infraspinatus tears and (2) evaluate the effect of SSC healing on postoperative clinical outcomes. Study Design: Cohort study; Level of evidence 3. Methods: A retrospective study was carried out in patients who underwent ARCR of isolated or combined SSC tears with a minimum 2-year follow-up. Three groups were compared: isolated SSC tear, anterosuperior rotator cuff tear with SSC tear (AS-RCT) and posterosuperior rotator cuff tear with SSC tear (PS-RCT). Patient-reported outcomes (PROs) and range of motion (ROM) were assessed pre- and postoperatively. SSC healing was evaluated via ultrasound at the final follow-up in a subset of patients. Results: The study included 588 patients with a minimum 2-year follow-up, of whom 279 underwent ultrasound assessments. PROs and ROM improved after ARCR in all groups (P .05), or between isolated SSC and PS-RCT groups (P > .05). There was no statistically significant difference when comparing the pre- to postoperative change in ROM between the groups (P > .05). The SSC healing rates for isolated SSC, AS-RCT, and PS-RCT groups were 88.1%, 91.6%, and 84.3%, respectively, (P >.24). There was no significant difference in ASES score or Subjective Shoulder Value (SSV) improvement between healed and unhealed groups in patients with isolated SSC tears (P > .05). ASES and SSV were significantly lower in unhealed SSC patients compared with those having a healed SSC in patients with AS-RCTs (ASES, P .01; SSV, P < .01). Conclusion: Both isolated and combined SSC repairs showed improvement in PROs and ROM. SSC healing rates did not differ between isolated and combined SSC tears. While failure to heal did not affect the clinical outcome of isolated SSC tears, an unhealed SSC was associated with lower functional scores in combined tears. Regardless of tear type, a healed SSC was associated with increased shoulder strength.ArthrexM.N. has received a grant from Arthrex and education payments from Rock Medical Orthopedics.

Exploring the thermal properties of gallium sulfide (GaS) for high-temperature applications
No full textThe thermal stability and decomposition behavior of gallium sulfide (GaS) material are critical factors in determining its suitability for high-temperature applications. This study comprehensively investigates the GaS compound using thermogravimetric analysis (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC) to assess its thermal stability, decomposition mechanisms, and potential applications. TGA results revealed that GaS exhibits remarkable thermal stability up to 722 degrees C, with a significant weight loss observed at temperatures exceeding 786 degrees C. The activation energy for the key decomposition process between 722 and 786 degrees C was calculated to be 257 kJ/mol, indicating an energy-intensive reaction involving sulfur evaporation and structural reorganization. DTA analysis highlighted a major endothermic event at 789 degrees C. Additionally, DSC analysis identified two thermal processes with activation energies of 117 and 53 kJ/mol, respectively. These findings demonstrate that GaS not only maintains its structural integrity at high temperatures but also possesses unique thermal properties, making it a promising candidate for high-temperature electronics, thermophotovoltaics, and sensor technologies where thermal robustness is essential.Scientific and Technological Research Council of Turkiye (TUBIdot;TAK)Open access funding provided by the Scientific and Technological Research Council of Turkiye (TUB & Idot;TAK)

Method: Research data were collected online through "Google Forms" by reaching women of reproductive age on social media platforms between December 2023 and December 2024. The study was conducted with 353 women who met the inclusion criteria. The data were collected using a Descriptive Information Form, the Premenstrual Syndrome Scale (PMSS) and the Self-Compassion Scale. The data were analyzed using descriptive statistical methods, independent sample t test, one-way analysis of variance (ANOVA), tukey test, pearson correlation analysis and multiple regression analysis. Results: The mean total score of the women who participated in the study was found to be 133.49 and the mean total score of the self-compassion scale was found to be 2.91. It was found that there was a negative and highly significant relationship between the total score of the PMSS and the total score of the self-compassion scale (r: -0.700, p<0.001). According to the results of the regression analysis, being married (?=0.152) and self-compassion (?=-0.698) were found to be the determinants of PMSS and these two variables predicted 49.5% of the total scale score. Conclusion: It was concluded that the self-compaasion of the women participating in the study was at a moderate level, the prevalence of PMS in women was 55%, the self-compassion of women who experienced PMS was lower than women who did not experience PMS, and as self-compasssion increased, the condition of experiencing PMS symptoms decreased
The effects of systemic adropin administration on biochemical and morphological effects in diabetic nephropathy: a rat model study|U?inci sistemske primjene adropina na biokemijske i morfološke pokazatelje kod dijabeti?ke nefropatije: istra?ivanje na modelu štakora.
No full textThe aim of the study was to investigate the biochemical and morphological effects of systemic adropin administration on renal tissue in streptozotocin-induced diabetic nephropathy in rats. The animals were divided into 4 groups as follows: control, adropin, diabetes, diabetes+adropin. The diabetic groups received a single dose of intraperitoneal streptozotocin (65 mg/kg). The fasting blood glucose level for diabetes was defined as at least 250 mg/dl. Eight weeks after administration of streptozotocin and/or the streptozotocin solvent to the adropin groups, 450 nmol/kg adropin was administered twice daily as an intraperitoneal injection for 10 days. The results of our study indicate that adropin administration has a significant impact on the adverse effects of diabetes on renal tissue. In particular, adropin administration resulted in a notable reduction in the high tissue total oxidant status, glomerular diameter, collagen fiber density, and vascular endothelial growth factor immunoreactivity observed in the diabetic group. These findings suggest that adropin has the potential to be a valuable therapeutic agent in reducing oxidative stress and improving histological and immunohistochemical changes in diabetic nephropathy. © 2025 Elsevier B.V., All rights reserved
Search for Nuclear Modifications of B+ Meson Production in p-Pb Collisions at ?sNN=8.16 TeV
No full textNuclear medium effects on B+ meson production are studied using the binary-collision scaled cross section ratio between events of different charged-particle multiplicities from proton-lead collisions. Data, collected by the CMS experiment in 2016 at a nucleon-nucleon center-of-mass energy of root s(NN) = 8.16 TeV, corresponding to an integrated luminosity of 175 nb(-1), were used. The scaling factors in the ratio are determined using a novel approach based on the Z -> mu(-) mu(+) cross sections measured in the same events. The scaled ratio for B+ is consistent with unity for all event multiplicities, putting stringent constraints on nuclear modification for heavy flavor.FWF; FNRS; FWO (Belgium); CNPq; CAPES; FAPERJ; FAPERGS; FAPESP (Brazil); BNSF (Bulgaria); MoST; NSFC (China); CSF (Croatia); RIF (Cyprus); SENESCYT (Ecuador); ERC PRG [MoER TK202]; Academy of Finland; MEC; CEA; CNRS/IN2P3 (France); SRNSF; BMBF; DFG; HGF (Germany); NKFIH (Hungary); DAE; DST; SFI (Ireland); INFN (Italy); NRF (Republic of Korea); MES (Latvia); MOE; UM (Malaysia); CONACYT; UASLP-FAI (Mexico); PAEC (Pakistan); FCT (Portugal); MESTD (Serbia); PCTI (Spain); MOSTR (Sri Lanka); Swiss Funding Agencies (Switzerland); NSTDA; TUBITAK; NASU (Ukraine); DOE; NSFWe congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

The spousal support and breastfeeding self-efficacy between mothers of healthy babies and babies in the NICU: a comparative and correlational study
No full textThis comparative and correlational study investigated the relationship between perceived spousal support and breastfeeding self-efficacy in mothers of healthy babies and babies hospitalized in the neonatal intensive care unit (NICU). The study was conducted with 416 mothers (206 mothers with healthy babies and 210 mothers whose babies were hospitalized in NICU) at a training and research hospital in western Türkiye. The results revealed no significant difference in the mean scores of the perceived spousal support (PSS) and breastfeeding self-efficacy scale (BSES) between the two groups (p >.05). However, the mean total score for perceived social support was higher among mothers of infants in the NICU. While a strong positive correlation was found between the total and subscale scores of perceived spousal support and the breastfeeding self-efficacy scores of mothers with NICU infants, only a weak positive correlation was observed in mothers of healthy infants. These findings underscore the critical role of perceived spousal support in fostering positive breastfeeding outcomes, especially for mothers of NICU-admitted infants. The results suggest that enhancing spousal support could significantly improve breastfeeding self-efficacy, particularly for mothers facing the additional challenges of caring for medically fragile infants. Lactation consultants, nurses and healthcare providers should prioritize family-centered approaches that actively involve both mothers and their partners in breastfeeding education and support. © 2025 Elsevier B.V., All rights reserved
Examining the Therapist Mindfulness in the Context of Therapeutic Alliance and Therapeutic Relationship: A Systematic Review
No full textThe objective of this study is to conduct a comprehensive review literature researches examining the relationships between therapist mindfulness and the therapeutic alliance and therapeutic relationship. To this end, articles published on the subject between 2006 and 2024 were identified through a search databases PubMed, Web of Science, Medline, Taylor & Francis Online, Science Direct, Turkish Psychiatry Index, ULAKBIM and TR Index databases using the identified keywords. After rigorous evaluation process based on the inclusion and exclusion criteria, 25 quantitative, qualitative and mixed methods studies were included in this study. Mindfulness practices were mostly conducted under the guidance of the Mindfulness-Based Stress Reduction programme, which includes a variety of practices such as body scanning, hatha yoga, sitting meditation, daily mindfulness practices and conscious relaxation exercises. The results showed that mindfulness supports the therapeutic alliance in a very consistent way. It was found that therapists' acceptance of themselves and their clients increased with the practice of mindfulness, and that clinicians with high levels of mindfulness were able to maintain the therapeutic alliance more effectively. It was found that clinicians who practised mindfulness on a weekly basis were able to engage in a stronger therapeutic alliance than those who did not practise at all, and clinicians with a high frequency of weekly practice were able to engage in a stronger therapeutic alliance than those with a low frequency of practice. In addition, mindfulness practice was found to support the therapeutic alliance through several mechanisms, such as reducing countertransference, increasing empathy, and increasing tolerance of negative emotions. In conclusion, the findings of this review suggest that increasing therapists' levels of mindfulness would be a highly worthwhile endeavour in terms of developing a strong therapeutic alliance
