Family nonuniversal Z′ models with protected flavor-changing interactions

We define a new class of $Z'$ models with neutral flavor-changing interactions at tree level in the down-quark sector. They are related in an exact way to elements of the quark mixing matrix due to an underlying flavored $U(1)'$ gauge symmetry, rendering these models particularly predictive. The same symmetry implies lepton-flavor non-universal couplings, fully determined by the gauge structure of the model. Our models allow to address presently observed deviations from the SM and specific correlations among the new physics contributions to the Wilson coefficients $C_{9,10}^{(\prime) \ell}$ can be tested in $b \to s \ell^+ \ell^-$ transitions. We furthermore predict lepton-universality violations in $Z'$ decays, testable at the LHC.
THE ROLE OF THE MAGNETIC FIELD IN THE INTERSTELLAR MEDIUM OF THE POST-STARBURST DWARF IRREGULAR GALAXY NGC 1569

NGC 1569 is a nearby dwarf irregular galaxy which underwent an intense burst of star formation 10–40 Myr ago. We present observations that reach surface brightnesses 2–80 times fainter than previous radio continuum observations and the first radio continuum polarization observations of this galaxy at 20 cm, 13 cm, 6 cm, and 3 cm. These observations allow us to probe the relationship of the magnetic field of NGC 1569 to the rest of its interstellar medium (ISM). We confirm the presence of an extended radio continuum halo at 20 cm and see for the first time the radio continuum feature associated with the western Hα arm at wavelengths shorter than 20 cm. Although, in general, the spectral indices derived for this galaxy steepen as one moves into the halo of the galaxy, there are filamentary regions of flat spectral indices extending to the edge of the galaxy. The spectral index trends in this galaxy support the theory that there is a convective wind at work in this galaxy. There is strong polarized emission at 3 cm and 6 cm and weak polarized emission at 20 cm and 13 cm. We estimate that the thermal fraction is 40%–50% in the center of the galaxy and falls off rapidly with height above the disk. Using this estimate, we derive a total magnetic field strength of 38 μG in the central regions and 10–15 μG in the halo. The magnetic field is largely random in the center of the galaxy; the uniform field is ∼3–9 μG and is strongest in the halo. Using our total magnetic field strength estimates and the results of previous observations of NGC 1569, we find that the magnetic pressure is the same order of magnitude but, in general, a factor of a few less than the other components of the ISM in this galaxy. The uniform magnetic field in NGC 1569 is closely associated with the Hα bubbles and filaments. We suggest that a supernova-driven dynamo may be operating in this galaxy. Based on our pressure estimates and the morphology of the magnetic field, the outflow of hot gas from NGC 1569 is clearly shaping the magnetic field, but the magnetic field in turn may be aiding the outflow by channeling gas out of the disk of the galaxy. Dwarf galaxies with extended radio continuum halos like that of NGC 1569 may play an important role in magnetizing the intergalactic medium.
Correlation Between the Frailty of Elderly Patients on Regular Haemodialysis and the Quality of Life of Their Family Caregivers: A Cross-Sectional Evaluation

Objective To investigate the correlation between the frailty status of elderly patients on regular haemodialysis and the quality of life of their family caregivers. Methods 90 elderly patients with regular haemodialysis and 90 family caregivers of the respective patients were selected from January 2020 to April 2021. The influencing factors of the caregivers’ quality of life and correlation between patient debility and caregiver quality of life were analyzed by general information questionnaire, Tilburg debility index scale, self-care ability scale, family caregiver-related quality-of-life scale and social support scale. Results The quality of life of the family caregivers of elderly patients on regular haemodialysis is at the medium level (4.50 ± 2.96). Multiple linear stepwise regression analysis shows that the ability of patients to take care of themselves, the degree of patients’ weaknesses, whether they care for non-dialysis patients, the time to care for patients, social support and the type of current residence have significant impacts on the quality of life of the caregivers (p < 0.001). Variance analysis showed that the fitting degree of linear regression equation is relatively high, and the regression equation is significant (F = 9.195, p < 0.001, R = 0.595, R2 = 0.315). The quality of life of caregivers is positively correlated with the ability of the patients to take care of themselves, the length of care, social support and type of current residence (p < 0.05). The degree of weakness in patients is negatively correlated with taking care of non-regular dialysis patients (p < 0.05). Conclusion The ability of patients to take care of themselves, the degree of weakness of the patients, social support and the type of current residence are the influencing factors of the burden on the family caregivers of maintenance haemodialysis patients.
Abundances and physical parameters for stars in the open clusters NGC 5822 and IC 4756

Context. Classical chemical analyses may be affected by systematic errors that would cause observed abundance differences between dwarfs and giants. For some elements, however, the abundance difference could be real. Aims. We address the issue by observing 2 solar-type dwarfs in NGC 5822 and 3 in IC 4756, and comparing their composition with that of 3 giants in either of the aforementioned clusters. We determine iron abundance and stellar parameters of the dwarf stars, and the abundances of calcium, sodium, nickel, titanium, aluminium, chromium, silicon, and oxygen for both the giants and dwarfs. For the dwarfs, we also estimate the rotation velocities, and and lithium abundances. We improve the cluster parameter estimates (distance, age, and reddening) by comparing existing photometry with new isochrones. Methods. We acquired UVES high-resolution, of high signal-to-noise ratio (S /N) spectra. The width of the cross correlation profiles was used to measure rotation velocities. For abundance determinations, the standard equivalent width analysis was performed differentially with respect to the Sun. For lithium and oxygen, we derived abundances by comparing synthetic spectra with observed line features. Results. We find an iron abundance for dwarf stars equal to solar to within the margins of error for IC 4756, and slightly above for NGC 5822 ([Fe/H] = 0.01 and 0.05 dex respectively). The 3 stars in NGC 4756 have lithium abundances between Log N(Li) ≈ 2.6 and 2.8 dex, the two stars in NGC 5822 have Log N(Li) ≈ 2.8 and 2.5, respectively. Conclusions. For sodium, silicon, and titanium, we show that abundances of giants are significantly higher than those of the dwarfs of the same cluster (about 0.15, 0.15, and 0.35 dex). Other elements may also undergo enhancement, but all within 0.1 dex. Indications of much stronger enhancements can be found using literature data. But artifacts of the analysis may be partly responsible for this.
Volunteer Retirement and Well-Being in Older Adults: A Longitudinal Study

The extant literature on volunteering has focused primarily on the many benefits of volunteering for older adults. However, the question rarely investigated is whether these benefits dissipate when older adults retire from their volunteering. Given the U.S. policy context wherein volunteering is promoted as a solution to the problems of aging, this research investigates the association between the loss of one’s volunteering role through retirement and well-being. Utilizing three waves of the U.S.-based National Social Life, Health, and Aging Project (NSHAP) (2005–2016) and a fixed-effects modeling approach, we find that the well-being of older adults, measured as self-reported health, happiness, and depressive risk, is negatively associated with volunteer retirement. Our study contributes to the literature on well-being and volunteering for older adults and is the first study focusing on this critical transition point in the life of older volunteers. In addition, policymakers and organizations must broaden their focus to include not only the recruitment and retention of older adult volunteers but also the transition out of volunteering that many of them will eventually face.
Effect of Ozonated Extra Virgin Olive Oil Gel in The Treatment of Peri-Implant Mucositis: A Retrospective Analysis of 20 Cases

Peri-Implant Mucositis (PM) is inflammation that affects the soft tissues surrounding the implant with a prevalence between 19% and 65% and if left untreated, it precedes to periimplantitis. Over time several clinical protocols for the management of PM have been proposed. They include mechanical debridement alone or with additional chemical decontamination. A retrospective analysis was conducted to evaluate the effects of an extra virgin olive oil-based gel in the treatment of PM in support of mechanical decontamination procedures in 20 subjects. Statistically significant improvements in clinical outcomes (bleeding on probing -BoP, plaque index -PI and probing depth -PD) were observed by comparing the values at baseline to three observation periods (p <0.001). Beyond the limits, this retrospective clinical study demonstrates that ozonated extra virgin olive oil gel allowed to effectively treat inflammation of peri-implant tissues and, due to its organoleptic characteristics and the absence of side effects, can represent a valuable therapy for the chemical management of peri-implant mucositis and for daily use in the context of supportive therapy.
CORONAL MASS EJECTION INITIATION: ON THE NATURE OF THE FLUX CANCELLATION MODEL

We consider a three-dimensional bipolar force-free magnetic field with a nonzero magnetic helicity, occupying a half-space, and study the problem of its evolution driven by an imposed photospheric flux decrease. For this specific setting of the Flux Cancellation Model describing coronal mass ejections occurring in active regions, we address the issues of the physical meaning of flux decrease, of the influence on field evolution of the size of the domain over which this decrease is imposed, and of the existence of an energetic criterion characterizing the possible onset of disruption of the configuration. We show that (1) the imposed flux disappearance can be interpreted in terms of transport of positive and negative fluxes toward the inversion line, where they get annihilated. (2) For the particular case actually computed, in which the initial state is quite sheared, the formation of a twisted flux rope and the subsequent global disruption of the configuration are obtained when the flux has decreased by only a modest amount over a limited part of the whole active region. (3) The disruption is produced when the magnetic energy becomes of the order of the decreasing energy of a semi-open field, and then before reaching the energy of the associated fully open field. This suggests that the mechanism leading to the disruption is nonequilibrium as in the case where flux is imposed to decrease over the whole region.
An Overwiev of the Number of Points of Algebraic Sets over Finite Fields

We determine an upper bound on the number of rational points of an affine or projective algebraic set defined over an algebraic closure of a finite field by a system of polynomial equations. A special attention is given to irreducible but not absolutely irreducible algebraic sets, which satisfy better bounds. We determine in the affine case some algebraic sets having the maximum number of rational points.
An Assessment of Student Pharmacists’ Knowledge of Electronic Cigarettes or Vapes—A Cross Sectional Study at One College of Pharmacy

This study assessed the knowledge of e-cigarettes/vapes among a sample of student pharmacists. A 22-item cross-sectional electronic questionnaire was administered to all third- and fourth-year student pharmacists enrolled at one college of pharmacy in the United States (N = 256). Data were collected over six weeks in March/April 2022. One point was assigned for each correct knowledge item; points were then summed to create a total knowledge score for each person. Differences in the proportion of students who correctly answered each knowledge item were compared between year groups using a chi-square test, while differences between year groups for total knowledge score were compared using a two-sample t-test. The a priori alpha level was 0.05. Fifty students (third year = 30, fourth year = 20; female = 60%) completed the survey. Students’ e-cigarettes/vapes knowledge varied depending on the item. There was no statistically significant difference between third- and fourth-year students for total mean knowledge scores (third year = 12.5 ± 3.3, fourth year = 11.2 ± 3.1, p = 0.1780) or for each knowledge item, except for items 10 and 20. In conclusion, the findings from this survey of student pharmacists at one college of pharmacy in the United States indicate a need for more education around e-cigarettes/vapes for student pharmacists so that they are better able to counsel patients on their use.
The Effect of English Proficiency on Chinese Learners’ L2 Refusals

This study investigated the effect of English proficiency on Chinese learners’ L2 refusal productions. 40 participants were divided into two groups according to proficiency and their refusals were elicited online using two low-setting open-ended role plays. Results demonstrated that English proficiency had a noteworthy influence on L2 refusals from both quantitative and qualitative perspectives. Different linguistic knowledge, the competence of processing, expression, and interaction, and degrees of negative L1 transfer all resulted in the different refusal performances of the two groups. Moreover, this study supported that even advanced English learners lack enough L2 pragmatic competence, which had pedagogical implications.
The Rare Association of Ectopic Pregnancy and Hydatidiform Mole: A Case Report

An ectopic molar pregnancy is a rare event, occurring in 1 in every 20,000–100,000 pregnancies. The condition may present as a complete or partial molar pregnancy and the ectopic site can vary as in a non-molar ectopic pregnancy. When a molar pregnancy presents as a tubal ectopic pregnancy, the risks related to both conditions, including tubal rupture and progress to malignancy, are compounded. The definitive diagnosis is normally reached by histopathology of the surgical specimen, since imaging tests are usually unable to differentiate between a molar and a non-molar ectopic pregnancy. While the specific histological findings may confirm the diagnosis of hydatidiform mole, immunohistochemistry is essential to differentiate between a complete and a partial molar pregnancy. Although in the majority of cases surgical resection is considered the definitive treatment, it is estimated that 20% of patients with a molar pregnancy may develop gestational trophoblastic neoplasia, hence requiring a risk-specific follow-up. This report describes a case of a tubal molar pregnancy and includes a review of clinical, diagnostic and therapeutic aspects, as well as a discussion on the particularities of this rare association.
Combining ability analyses of grain yield and kernel micronutrient content in maize (Zea mays)

The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and yield related traits. Nine inbred lines were crossed with two testers using line × tester mating design. Nine lines, two testers and 18 experimental hybrids were evaluated along with two checks in this study for grain yield and protein content, besides kernel micronutrients (phosphorous, caicium and iron) during kharif 2019 in a randomized block design at experimental farm of BAC, Sabour. The line CLQRCY44 and HKI1532 were found as good general combiner for grain yield and quality traits followed by DHOLI inbred 55 and CLO2450. Lines DHOLI inbred 55 and CML451 were found as good general combiner for earliness, lines CLQRCY44, CLO2450 and DHOLI 55 for quality traits like protein content, calcium content, phosphorous and iron content. Among the crosses, HKI1532 × 95IOWA (67.43 q/ha), LM13 × SUWAN (65.87 q/ha) and CML425 × SUWAN (63.30 q/ha) were the promising crosses for grain yield. CLO2450 × SUWAN and LM13 × SUWAN exhibited highly significant and desirable SCA effects for grain yield. CLO2450 × 95IOWA exhibited highly significant and desirable SCA effects for protein content. HKI1532 × 95IOWA (67.43 q/ha) was the promising hybrid for grain yield and micronutrient content. Therefore, these crosses can be utilized for developing high yielding micronutrient enriched hybrid varieties in maize (Zea mays L).
Evaluation of Tissue Expression of Vaspin and Serum Vaspin Concentration as a Prognostic and Risk Factor in Endometrial Cancer

Adipose tissue is a multifunctional endocrine organ. One of the biologically active substances is vaspin, which is part of the serpin family. The purpose of the following study is to determine the possibility of using vaspin as a prognostic and risk factor in endometrial cancer. The study included 127 patients with abnormal uterine bleeding. To determine the value of adipokine, the study used Kaplan-Meier curves to estimate patients survival. Univariate and multivariate analyses were performed simultaneously using the Cox regression model. Tissue expression of vaspin was assessed in patients from the study group (endometrial cancer) and the control group (non-cancerous). We found that higher levels of vaspin are found in obese people, with lower staging (FIGO I and II), lower grading (G1), no LVSI metastases and no lymph node metastases. Higher serum vaspin levels are an independent protective factor for endometrial cancer. We concluded that endometrial cancer patients with serum vaspin concentrations above the median have longer DFS compared to patients with concentrations below the median. Considering multivariate analysis, vaspin concentrations above the median are independent favourable prognostic factors for endometrial cancer. Tissue expression of vaspin cannot be a histological marker to distinguish between cancer and non-cancerous lesions and between different grading levels.
Generating resonating-valence-bond states through Dicke subradiance

Dicke's original thought experiment with two spins (two-level atoms) coupled to a photon mode has recently been experimentally realized. We propose extending this experiment to many spins as a way to synthesize highly entangled states. We suggest a protocol in which we start with a direct product state of $M$ atoms in the excited state and $N$ atoms in the ground state, placed within a lossy cavity. A null observation for photon emission collapses the system onto a dark state which, remarkably, has resonating-valence-bond (RVB) character. We demonstrate this by taking advantage of the symmetry of the initial state under permutations of the $M$ excited atoms and of the $N$ unexcited atoms. Using angular momentum analysis, we reexpress the wave function of the dark state to illustrate its RVB character. We discuss two limiting cases in detail, with $M=1$ (one excited atom) and $M=N$ (equal number of excited and unexcited atoms). In the latter case, we show that the probability for null emission scales as ${N}^{\ensuremath{-}1}$, making it possible to generate highly entangled RVB states of 20 spins or more.
Unexpected Heterogeneity of Newly Diagnosed Multiple Myeloma Patients with Plasmacytomas

In multiple myeloma (MM), malignant plasma cells infiltrate the bone marrow. In some cases, plasma cells migrate out of the bone marrow creating either para-skeletal plasmacytomas (PS) or infiltrating soft tissues as extramedullary plasmacytomas (EMD). The aim of this study was to define risk groups in newly diagnosed MM (NDMM) patients with PS and EMD plasmacytomas. In total, 523 NDMM patients with PS plasmacytomas and 196 NDMM patients with EMD plasmacytomas were diagnosed in the Czech Republic between 2004 and 2021 using modern imaging methods. Patients’ data were analyzed from the Registry of Monoclonal Gammopathies of the Czech Myeloma Group. In NDMM patients with PS plasmacytomas, we found a subgroup with <5% of bone-marrow plasma cells to have the best prognosis (mPFS: 58.3 months (95% CI: 33.0–NA); mOS: not reached). The subgroup with >5% of bone-marrow plasma cells and ≥3 plasmacytomas had the worst prognosis (mPFS: 19.3 months (95% CI: 13.4–28.8), p < 0.001; mOS: 27.9 months (95% CI: 19.3–67.8), p < 0.001). Our results show association between tumor burden and prognosis of NDMM patients with plasmacytomas. In the case of PS plasmacytomas, NDMM patients with low BM PC infiltration have an excellent prognosis.
Volume Analysis to Predict the Long-Term Evolution of Residual Aortic Dissection after Type A Repair

Background: The aim of this study was to evaluate the aortic diameter and volume during the first year after a type A repair to predict the long-term prognosis of a residual aortic dissection (RAD). Methods: All patients treated in our center for an acute type A dissection with a RAD and follow-up > 3 years were included. We defined two groups: group 1 with dissection-related events (defined as an aneurysmal evolution, distal reintervention, or aortic-related death) and group 2 without dissection-related events. The aortic diameters and volume analysis were evaluated on three postoperative CT scans: pre-discharge (T1), 3–6 months (T2) and 1 year (T3). Results: Between 2009 and 2016, 54 patients were included. Following a mean follow-up of 75.4 months (SD 31.5), the rate of dissection-related events was 62.9% (34/54). The total aortic diameters of the descending thoracic aorta were greater in group 1 at T1, T2 and T3, with greater diameters in the FL (p < 0.01). The aortic diameter evolution at 3 months was not predictive of long-term dissection-related events. The total thoracic aortic volume was significantly greater in group 1 at T1 (p < 0.01), T2 (p < 0.01), and T3 (p < 0.01). At 3 months, the increase in the FL volume was significantly greater in group 1 (p < 0.01) and was predictive for long-term dissection-related events. Conclusion: This study shows that an initial CT scan volume analysis coupled with another at 3 months is predictive for the long-term evolution in a RAD. Based on this finding, more aggressive treatment could be given at an earlier stage.
