Fetal Trans-Cerebellar Diameter and Fetal Trans-Cerebellar Diameter to Abdominal Circumference [tcd/ac] Ratio in Assessment of Gestational Age for the Prediction of Normal Fetal Growth and Intrauterine Growth Restriction

Background: Accurate estimation of the gestational age [GA] is crucial for the appropriate management of pregnancy. Inaccurate GA estimation is associated with adverse perinatal outcomes. Precise knowledge of the expected date of delivery has a vital role in the management of pregnancies. Amongst the several clinical measures employed to assess the GA, the date of the last normal menstrual period [LNMP] is acknowledged to relate best with the GA. However, this method may not be always reliable and can sometimes be misleading. Foetal Abdominal Circumference [AC] is one the important foetal parameters to be affected early in the process of impaired foetal growth. So, Trans cerebellar Diameter/Abdominal Circumference [TCD/AC] ratio has been found to be constant and a gestational age independent parameter to assess foetal growth and can be useful in predicting foetal growth restriction. The aim of the present study was to evaluate accuracy of fetal trans-cerebellar diameter and fetal trans-cerebellar diameter to abdominal circumference [TCD/AC] ratio in assessment of gestational age for the prediction of normal fetal growth and intrauterine growth restriction. Methods: This was a prospective case control study conducted at the Obstetrics and Gynecology Department, Hospital, – on 300 pregnant women [Group A]: included healthy pregnant women with morphologically normal fetuses between 14-40 weeks of gestation who came for routine antenatal sonography, [Group B]: included patients of suspected IUGR clinically. Results: HC, AC, and TCD were significantly lower in IUGR compared to controls. Meanwhile TCD/AC was significantly higher in IUGR compared to controls. Conclusion: In IUGR fetuses, the fetal TCD was less affected than fetal HC suggesting preferential preservation of cerebellar growth relative to other cranial structures. The TCD/AC ratio was helpful in recognizing abnormal fetal growth. Even when the GA was uncertain since this ratio was gestational age independent.
Genetic evaluation of F2 inbred strain of Swiss albino mice by microsatellite markers

Genetic characterization of F2 inbred Swiss albino mice was done using 11 microsatellites markers (D1Mit15, D2Mit51, D2Mit61, D3Mit15, D3Mit55, D5Mit18, D7Mit323, D8Mit14, D9Mit27, D10Mit180, and D11Mit167). The results indicated that genotypic frequencies at all the loci were in Hardy-Weinberg disequilibrium (P<0.001). Total number of alleles per locus ranged from 3 (D2Mit61, D3Mit15, D8Mit14, D9Mit27, D10Mit180, D11Mit167) to 4 (D1Mit15, D2Mit51, D3Mit55, D5Mit18, D7Mit323), with a mean of 3.45. The numbers of effective alleles ranged between 1.847 and 3.814. The observed heterozygosity (Ho) was maximum for D1Mit15 (0.660) and minimum for D5Mit18 (0.080), with mean of 0.269. The FIS estimates was ranged from 0.0817 (D1Mit15) to 0.8799 (D5Mit18). The average inbreeding coefficient was 0.592, which indicates that parents were more related than expected under random mating. The range of PIC value (from 0.414 to 0.689) for various microsatellite loci was revealing that population under investigation was of high diversity maintaining a multiple allele.
Does Corporate Governance Constrain Earnings Management in an Unstable Economic and Political Environment?

The purpose of this research is to examine the effects of corporate governance structures on earnings management behavior in a weakly governed and politically unstable environment. A panel of data from 35 non-bank companies listed on the Palestine Exchange between 2012 and 2019 was employed. A fixed effects regression model was used to examine the impact of certain board characteristics (board size, board meetings, and audit committee formation) and ownership structures (institutional ownership, foreign ownership, and ownership concentration) on earnings management in the volatile and risky political and economic environment of Palestine. The findings indicate that corporate governance and ownership systems in Palestine appear to be ineffective in constraining earnings management practices. None of the board attributes appear to constrain earnings management practices. However, there is weak evidence to show that ownership concentration has some effect in curbing earnings manipulation. The findings of this study are expected to increase awareness among Palestinian regulators, investors, and other policymakers regarding the role of boards of directors and institutional and foreign shareholders in monitoring Palestinian listed companies to enhance corporate governance and the quality of financial reporting.
Prediction and estimation of growth curves with special covariance structures

Abstract The model considered here is a generalized multivariate analysis-of-variance model useful especially for many types of growth-curve problems, including biological growth and technology substitutions. It is defined as Yp × N = Xp×mτm×rAr×N + ∈p×N , where τ is unknown and X and A are known design matrices of ranks m < p and r < N, respectively. Further, the columns of ∈ are independent p-variate normal, with mean vector 0 and common covariance matrix Σ. In general, p is the number of time (or spatial) points observed on each of the N cases, (m — 1) is the degree of polynomial, and r is the number of groups. This article focuses mainly on predicting future observations, including partially observed vectors and future values on a given number of cases, using their past observations. These prediction problems, as well as the estimation of parameters, are considered for two parsimonious covariance structures that are very important in practice. The results are illustrated with three real data sets. Som.
Characterization of the Hardy property of means and the best Hardy constants

The aim of this paper is to characterize in broad classes of means the so-called Hardy means, i.e., those means $M\colon\bigcup_{n=1}^\infty \mathbb{R}_+^n\to\mathbb{R}_+$ that satisfy the inequality $$ \sum_{n=1}^\infty M(x_1,\dots,x_n) \le C\sum_{n=1}^\infty x_n $$ for all positive sequences $(x_n)$ with some finite positive constant $C$. One of the main results offers a characterization of Hardy means in the class of symmetric, increasing, Jensen concave and repetition invariant means and also a formula for the best constant $C$ satisfying the above inequality.
EFECTS OF SUPPLEMENTAL FEEDING FOR DIFFERENT PERIODS ON THE PRODUCTIVITY OF HONEY BEE DRONES

: The investigation was carried out in apiary at Sohag region during the period from the first of January to the first of April, 2008. The effects of supplemental feeding for different periods on activity of colonies, and their relation to drones production were studied. Positive correlations were found between supplemental feeding and each of bee population size, workers and drones brood-rearing activity, stored pollen and weight of both drone body and mucus gland. Bee colonies fed on supplemental feeding at different periods produced significantly more bees, workers and drones brood and stored pollen than unfed control colonies. The maximum average of each of bee population size (11361 bee/ colony), workers brood area (605.2 inch 2 /colony) and stored pollen (80.7 inch 2 / colony) resulted from bee colonies fed for 10-weeks period. Whereas the feeding period of 8-weeks gave the highest average of drones brood (34.6 inch 2 / colony), marking a 64.8% increment as compared with unfed control colonies. The feeding period of 10-weeks gave the highest average weight of both mature drone body (180.8 mg) and mucus gland (12.8 mg), inducing 12.3% and 19.6% increment in weight of drone body and mucus gland, respectively relative to the unfed control. Meanwhile, the highest increment in weight of newly emerged drones was 4.8% resulted from 10-weeks feeding period. The coefficient of determination was 0.21, indicating that the feeding periods, bee population, workers brood, and stored pollen accounted for 21% of drone production changes.
Advection-diffusion equations with density constraints

In the spirit of the macroscopic crowd motion models with hard congestion (i.e., a strong density constraint ρ≤1) introduced by Maury et al. some years ago, we analyze a variant of the same models where diffusion of the agents is also taken into account. From the modeling point of view, this means that individuals try to follow a given spontaneous velocity, but are subject to a Brownian diffusion, and have to adapt to a density constraint which introduces a pressure term affecting the movement. From the point of view of PDEs, this corresponds to a modified Fokker–Planck equation, with an additional gradient of a pressure (only living in the saturated zone {ρ=1}) in the drift. We prove existence and some estimates, based on optimal transport techniques.
Recirculation within a fluid sphere at moderate Reynolds numbers

Motion of a single fluid sphere is described by two theories, each characterized by different levels of Hill's vortex circulation within the sphere. An existing experimental data set giving measurements of vertical velocity along the major axis of the sphere is re-examined. Contrary to published discussions of that experiment, we find that the theory of Parlange agrees better with the laboratory data than that of Harper & Moore. This agreement supports the key difference between the two theories, i.e. that the fluid within the sphere is unlikely to have a singular (infinite) velocity as it moves upwards towards the stagnation region at the top of the sphere.
Scaling limits of correlations of characteristic polynomials for the Gaussian beta-ensemble with external source

We study the averaged product of characteristic polynomials of large random matrices in the Gaussian beta-ensemble perturbed by an external source of finite rank. We prove that at the edge of the spectrum, the limiting correlations involve two families of multivariate functions of Airy and Gaussian types. The precise form of the limiting correlations depends on the strength of the nonzero eigenvalues of the external source. A critical value for the latter is obtained and a phase transition phenomenon similar to that of arXiv:math/0403022 is established. The derivation of our results relies mainly on previous articles by the authors, which deal with duality formulas arXiv:0801.3438 and asymptotics for Selberg-type integrals arXiv:1112.1119v3.
FACTORIALS OF INFINITE CARDINALS IN ZF PART II: CONSISTENCY RESULTS

Abstract For a set x, let ${\cal S}\left( x \right)$ be the set of all permutations of x. We prove by the method of permutation models that the following statements are consistent with ZF: (1) There is an infinite set x such that $|\wp \left( x \right)| < |{\cal S}\left( x \right)| < |se{q^{1 - 1}}\left( x \right)| < |seq\left( x \right)|$, where $\wp \left( x \right)$ is the power set of x, seq (x) is the set of all finite sequences of elements of x, and seq1-1 (x) is the set of all finite sequences of elements of x without repetition. (2) There is a Dedekind infinite set x such that $|{\cal S}\left( x \right)| < |{[x]^3}|$ and such that there exists a surjection from x onto ${\cal S}\left( x \right)$. (3) There is an infinite set x such that there is a finite-to-one function from ${\cal S}\left( x \right)$ into x.
Compact Locally Conformally Flat Riemannian Manifolds

First, we shall prove that a compact connected oriented locally conformally flat n‐dimensional Riemannian manifold with constant scalar curvature is isometric to a space form or a Riemannian product Sn−1(c) × S1 if its Ricci curvature is nonnegative. Second, we shall give a topological classification of compact connected oriented locally conformally flat n‐dimensional Riemannian manifolds with nonnegative scalar curvature r if the following inequality is satisfied: ∑i,jRij2⩽r2/(n − 1) , where ∑i,jRij2 is the squared norm of the Ricci curvature tensor.
Virtual braids and permutations

Let VB_n be the virtual braid group on n strands and let S_n be the symmetric group on n letters. Let n, m ∈ N such that n ≥ 5, m ≥ 2 and n ≥ m. We determine all possible homomorphisms from VB_n to S_m , from S_n to VB_m and from VB_n to VB_m. As corollaries we get that Out(VB_n) is isomorphic to the Klein group and that VB_n is both Hopfian and co-Hofpian.
Regular Homotopy Classes of Singular Maps

Two locally generic maps f, g : Mn R2n − 1 are regularly homotopic if they lie in the same path‐component of the space of locally generic maps. Our main result is that if n ≠ 3 and Mn is a closed n‐manifold then the regular homotopy class of every locally generic map f : Mn R2n − 1 is completely determined by the number of its singular points provided that f is singular (that is, f is not an immersion). 2000 Mathematics Subject Classification 57R45, 58K30, 57R42.
About Crows and Nightingales: Which Factors Predict Vocal Abilities in Elementary School Children?

In this study, we explored associations between perception of musical features (pitch, tonality, timing, timbre, and loudness), vocal abilities (singing accuracy, melodic achievement, and rhythmic performance), and cognitive levels (reading accuracy and comprehension, grammar, and math) among children ages 6 to 12. Musical perception abilities were measured using the Implicit Tonal Ability Test. Vocal abilities were measured using the Vocal Musical Ability Test. Cognitive levels were measured using standardized Dutch performance tests on academic skills. We investigated which factors (age, gender, cognitive levels, school type, music perception abilities, and participation in music education) predict vocal abilities and how these abilities differed by age. Results showed that singing accuracy was best predicted by gender, math level, and music perception abilities. Melodic achievement was best predicted by age, school type, math level, and music perception abilities. Rhythmic performance was best predicted by age, instrumental music education, and music perception abilities. Regardless of their age, differences in singing abilities between children were large. We advise teachers to provide activities in which repetition and prediction of patterns, scales, all intervals, and intonation are practiced, including transposing melodies and repeating rhythmic patterns.
The characteristic polynomial of a random unitary matrix and Gaussian multiplicative chaos - The $L^2$-phase

We study the characteristic polynomial of Haar distributed random unitary matrices. We show that after a suitable normalization, as one increases the size of the matrix, powers of the absolute value of the characteristic polynomial as well as powers of the exponential of its argument converge in law to a Gaussian multiplicative chaos measure for small enough real powers. This establishes a connection between random matrix theory and the theory of Gaussian multiplicative chaos.
Trace and Künneth formulas for singularity categories and applications

We present an $\ell$-adic trace formula for saturated and admissible dg-categories over a base monoidal differential graded (dg)-category. Moreover, we prove Künneth formulas for dg-category of singularities and for inertia-invariant vanishing cycles. As an application, we prove a categorical version of Bloch's conductor conjecture (originally stated by Spencer Bloch in 1985), under the additional hypothesis that the monodromy action of the inertia group is unipotent.
Staphylococcus aureus from Subclinical Cases of Mastitis in Dairy Cattle in Poland, What Are They Hiding? Antibiotic Resistance and Virulence Profile

Bovine mastitis is a common disease worldwide, and staphylococci are one of the most important etiological factors of this disease. Staphylococcus aureus show adaptability to new conditions, by which monitoring their virulence and antibiotic resistance mechanisms is extremely important, as it can lead to the development of new therapies and prevention programs. In this study, we analyzed Staphylococcus aureus (n = 28) obtained from dairy cattle with subclinical mastitis in Poland. The sensitivity of the isolated strains to antibiotics were confirmed by the disc diffusion method. Additionally, minimum inhibitory concentration values were determined for vancomycin, cefoxitin and oxacillin. Genotyping was performed by two methods: PCR melting profile and MLVF-PCR (multiple-locus variable-number tandem-repeat fingerprinting). Furthermore, the presence of antibiotic resistance and virulence genes were checked using PCR reactions. The analyzed strains showed the greatest resistance to penicillin (57%), oxytetracycline (25%) and tetracycline (18%). Among the analyzed staphylococci, the presence of 9 of 15 selected virulence-related genes was confirmed, of which the icaD, clfB and sea genes were confirmed in all staphylococci. Biofilm was observed in the great majority of the analyzed bacteria (at least 70%). In the case of genotyping among the analyzed staphylococci (combined analysis of results from two methods), 14 patterns were distinguished, of which type 2 was the dominant one (n = 10). This study provides new data that highlights the importance of the dominance of biofilm over antibiotic resistance among the analyzed strains.
Optimal Management of Dysphagia in Patients with Inoperable Esophageal Cancer: Current Perspectives

Abstract The majority of patients with esophageal cancer are diagnosed at an advanced, incurable stage. Palliation of symptoms, specifically dysphagia, is a crucial component to improve quality of life and optimize nutritional status. Despite multiple available treatment modalities, there is not one accepted or recommended to be the preferred treatment option. Palliative management is often decided by a multidisciplinary team considering factors including local availability, preference, patient life expectancy, and symptom severity. Systemic therapies such as chemotherapy are the most commonly used palliative modalities. Oncologists are most familiar with radiation for dysphagia palliation, especially for advanced metastatic cancer patients with good performance status. One common approach used by endoscopist is self-expandable metal stents. This is preferred for patients with short-term survival and poor functional status as it provides rapid relief of dysphagia. Cryotherapy is a relatively new endoscopic ablative modality and appears to be a promising option for dysphagia palliation, but more data is needed for wider adoption. This review summarizes the current literature on endoscopic and non-endoscopic treatment options for malignant dysphagia.
Differential Equations with a Difference Quotient

The purpose of this paper is to study a class of ill-posed differential equations. In some settings, these differential equations exhibit uniqueness but not existence, while in others they exhibit existence but not uniqueness. An example of such a differential equation is, for a polynomial $P$ and continuous functions $f(t,x):[0,1]\times [0,1]\rightarrow \mathbb{R}$, \begin{equation*} \frac{\partial}{\partial t} f(t,x) = \frac{ P(f(t,x))-P(f(t,0))}{x}, \quad x>0. \end{equation*} These differential equations are related to inverse problems.
Trends and Projections of Stomach Cancer Incidence in Hong Kong: A Population-Based Study

Abstract Objectives The burden of stomach cancer remains high in Hong Kong. We sought to evaluate the associations of age, period, and birth cohort with the changing trend in the incidence of stomach cancer and to provide projections through 2030. Materials and Methods We performed an age-period-cohort analysis and projections up to 2030 using data from the Hong Kong Cancer Registry. Additionally, we used a population decomposition algorithm to assess the drivers in the number of incident cases of stomach cancer in Hong Kong. Results Among the 26,813 stomach cancer patients, from 1994 to 2018, the age-standardized incidence rate of stomach cancer decreased for both sexes. The incidence increased with age and was highest for those aged 85 years or older. Period relative risk (RR) showed a monotonic decreasing pattern throughout the study period for both sexes before 2010. Cohort RR for males was monotonically decreasing but changed little after the 1967–1971 birth cohort. In contrast, cohort RR for females declined in the pre-1927–1931 birth cohort but slowed down since. It is projected that there will be 906 male patients and 954 female patients in 2030. Decomposition analysis suggested that population growth and aging were associated with substantial changes in the number of incident cases of stomach cancer in Hong Kong. Conclusions Both period and cohort risk of developing stomach cancer in Hong Kong have slowed down or plateaued. Our study demonstrates that population aging and growth are the main drivers of the increased number of incident cases of stomach cancer in Hong Kong.
Stability analysis of delay differential equations via Semidefinite programming

This paper demonstrates that after descretizing a linear delay differential equations (DDE), see (1.1) in the paper, then the stability of the DDE can be analyzed by solving a semi-definite programming (SDP), see (3.2) in this paper, in short, DDE (1.1) is stable if and only if SDP (3.2) has a solution with t<1.
Cofilin Acts as a Booster for Progression of Malignant Tumors Represented by Glioma

Abstract Cofilin, as a depolymerization factor of actin filaments, has been widely studied. Evidences show that cofilin has a role in actin structural reorganization and dynamic regulation. In recent years, several studies have demonstrated a regulatory role for cofilin in the migration and invasion mediated by cell dynamics and epithelial to mesenchymal transition (EMT)/EMT-like process, apoptosis, radiotherapy resistance, immune escape, and transcriptional dysregulation of malignant tumor cells, particularly glioma cells. On this basis, it is practical to evaluate cofilin as a biomarker for predicting tumor metastasis and prognosis. Targeting cofilin regulating kinases, Lin11, Isl-1 and Mec-3 kinases (LIM kinases/LIMKs) and their major upstream molecules inhibits tumor cell migration and invasion and targeting cofilin-mediated mitochondrial pathway induces apoptosis of tumor cells represent effective options for the development of novel anti-malignant tumor drug, especially anti-glioma drugs. This review explores the structure, general biological function, and regulation of cofilin, with an emphasis on the critical functions and prospects for clinical therapeutic applications of cofilin in malignant tumors represented by glioma.
