Background: Increasing breast cancer (BC) incidence rates have been reported from India; causal factors for this increased incidence are not understood and diagnosis is mostly in advanced stages. Trivandrum exhibits the highest BC incidence rates in India. This study aimed to estimate trends in incidence by age from 2005-2014, to predict rates through 2020 and to assess the stage at diagnosis of BC in Trivandrum. Materials and Methods: BC cases were obtained from the Population Based Cancer Registry, Trivandrum. Distribution of stage at diagnosis and incidence rates of BC [Age-specific (ASpR), crude (CR) and age-standardized (ASR)] are described and employed with a joinpoint regression model to estimate average annual percent changes (AAPC) and a Bayesian model to estimate predictive rates. Results: BC accounts for 31% (2681/8737) of all female cancers in Trivandrum. Thirty-five percent (944/2681) are <50 years of age and only 9% present with stage I disease. Average age increased from 53 to 56.4 years (p=0.0001), CR (per $10^5$ women) increased from 39 (ASR: 35.2) to 55.4 (ASR: 43.4), AAPC for CR was 5.0 (p=0.001) and ASR was 3.1 (p=0.001). Rates increased from 50 years. Predicted ASpR is 174 in 50-59 years, 231 in > 60 years and overall CR is 80 (ASR: 57) for 2019-20. Conclusions: BC, mostly diagnosed in advanced stages, is rising rapidly in South India with large increases likely in the future; particularly among post-menopausal women. This increase might be due to aging and/or changes in lifestyle factors. Reasons for the increased incidence and late stage diagnosis need to be studied.

Mathew, Bijo,Baek, Seung Cheol,Grace Thomas Parambi, Della,Pil Lee, Jae,Joy, Monu,Annie Rilda, P. R.,Randev, Rugma V.,Nithyamol, P.,Vijayan, Vijitha,Inasu, Sini T.,Mathew, Githa Elizabeth,Lohidakshan, The Royal Society of Chemistry 2018 MedChemComm Vol.9 No.11

<P>A series of 13 phenyl substituted thiosemicarbazones (SB1-SB13) were synthesized and evaluated for their inhibitory potential towards human recombinant monoamine oxidase A and B (MAO-A and MAO-B, respectively) and acetylcholinesterase. The solid state structure of SB4 was ascertained by the single X-ray diffraction technique. Compounds SB5 and SB11 were potent for MAO-A (IC50 1.82 ± 0.14) and MAO-B (IC50 0.27 ± 0.015 μM), respectively. Furthermore, SB11 showed a high selectivity index (SI > 37.0) for MAO-B. The effects of fluorine orientation revealed that SB11 (<I>m</I>-fluorine) showed 28.2 times higher inhibitory activity than SB12 (<I>o</I>-fluorine) against MAO-B. Furthermore, inhibitions by SB5 and SB11 against MAO-A and MAO-B, respectively, were recovered to near reference levels in reversibility experiments. Both SB5 and SB11 showed competitive inhibition modes, with <I>K</I>i values of 0.97 ± 0.042 and 0.12 ± 0.006 μM, respectively. These results indicate that SB5 and SB11 are selective, reversible and competitive inhibitors of MAO-A and MAO-B, respectively. Compounds SB5, SB7 and SB11 showed moderate inhibition against acetylcholinesterase with IC50 values of 35.35 ± 0.47, 15.61 ± 0.057 and 26.61 ± 0.338 μM, respectively. Blood-brain barrier (BBB) permeation was studied using the parallel artificial membrane permeation assay (PAMPA) method. Molecular docking studies were carried out using AutoDock 4.2.</P>

A Short Note on Inclusive and Exclusive Plurals in Korean

Michael Jonathan Mathew Barrie(Michael Jonathan Mathew Barrie ),Éric Mathieu(Éric Mathieu ) 한국생성문법학회 2023 생성문법연구 Vol.33 No.1

The aim of this short article is to give a comprehensive analysis of number in Korean, adding a novel observation about the interpretation of plurals in that language. Based on the new data, our proposal is that number is distributed along the nominal spine with different effects depending on the type of functional head (and semantic features) it is associated with. In particular, we propose that number in Korean is associated with two number projections, NumP1 and NumP2, (see Watanabe 2010 for Japanese, Vazquez Rojas Maldonado 2012 for Purépecha (isolate, tsz), Dali and Mathieu 2021 for Tunisian Arabic (Afro-Asiatic, aeb)). By shedding light on the distinction between inclusive and exclusive plurals in Korean and the relationship between definiteness and plurality, we contribute to the current debate related to the distribution of the Korean plural.

Dissecting Inchoatives and Causatives: English get constructions

Barrie Michael Jonathan Mathew,성문현 한국언어정보학회 2018 언어와 정보 Vol.22 No.3

Barrie, Michael Jonathan Mathew and Sung, Moonhyun. 2018. Dissecting Inchoatives and Causatives: English get Constructions. Language and Information, 22.3. 91-108. In this paper, we present data from English get-constructions and from Northern Iroquoian to challenge the recent consensus that in no languages are causatives built on inchoatives. Our data suggest the need for distinct functional projections for the causative and inchoative. We argue that while they are bundled in other situations, the functional heads for the causative and inchoative can be split as described in the present paper. This line of research follows recent trends in investigating the fine structure of the vP layer (Alexiadou et al. 2015, Harley 2013, Kim 2011, Marantz 2013, Pylkkänen 2008, Ramchand 2008, Legate 2014). We propose a syntactic mechanism for bundling and, in doing so, account for differences in the range of possible meanings with adverbs between canonical causatives and get-causatives. Briefly, get-causatives have unbundled causative and inchoative heads and have a wider ranger of adverbial meanings due to the projection of independent CausP and InchP. Canonical causatives have a bundled Caus-Inch head, projecting a single Caus/InchP, which leads to fewer sites for adverbs to adjoin and accordingly to a narrower range of adverbial meanings.

CONSTRAINTS ON PRE-INFLATION COSMOLOGY AND DARK FLOW

MATHEWS, GRANT J.,LAN, N.Q.,KAJINO, T. The Korean Astronomical Society 2015 天文學論叢 Vol.30 No.2

If the present universe is slightly open then pre-inflation curvature would appear as a cosmic dark-flow component of the CMB dipole moment. We summarize current cosmological constraints on this cosmic dark flow and analyze the possible constraints on parameters characterizing the pre-inflating universe in an inflation model with a present-day very slightly open ${\Lambda}CDM$ cosmology. We employ an analytic model to show that for a broad class of inflation-generating effective potentials, the simple requirement that the observed dipole moment represents the pre-inflation curvature as it enters the horizon allows one to set upper and lower limits on the magnitude and wavelength scale of pre-inflation fluctuations in the inflaton field and the curvature parameter of the pre-inflation universe, as a function of the fraction of the total initial energy density in the inflaton field. We estimate that if the current CMB dipole is a universal dark flow (or if it is near the upper limit set by the Planck Collaboration) then the present constraints on ${\Lambda}CDM$ cosmological parameters imply rather small curvature ${\Omega}_k{\sim}0.1$ for the pre-inflating universe for a broad range of the fraction of the total energy in the inflaton field at the onset of inflation. Such small pre-inflation curvature might be indicative of open-inflation models in which there are two epochs of inflation.

Cure kinetics of ethylene acrylate rubber/clay nanocomposites

Mathew, G.,Rhee, J.M.,Lee, Y.S.,Park, D.H.,Nah, C. Korean Society of Industrial and Engineering Chemi 2008 Journal of industrial and engineering chemistry Vol.14 No.1

This work reports some new findings for organoclay dispersion and its effect on the cure behavior of ethylene acrylate rubber (EAR)/clay nanocomposites, which were prepared by melt mixing procedure. Based on the X-ray diffraction (XRD) and transmission electron microscopy (TEM) observation, the organoclay-filled EAR composites showed a fairly good dispersion composed of a mixture of intercalated and exfoliated clay layers at relatively lower clay contents below 10phr, but a partial re-aggregation of clays was formed with further increase of organoclay. While the organoclay enhanced the rate of cure of EAR based on the cure rheometer, the pristine clay showed much smaller effect. The autocatalytic model showed a close fitting with experimental values for cure rates with the correlation coefficient (R<SUP>2</SUP>) of ∼0.98, proving the validity of the model for describing the cure behavior of the system. The glass transition temperature slightly shifted to higher temperatures by employing the organoclay because of the restriction in motion of EAR chain segments in the clay galleries.

The objective of this study was to determine the effect of different stocker management programs on skeletal muscle development and growth characteristics, satellite cell (SC) activity in growing-finishing beef cattle as well as the effects of SC-conditioned media on preadipocyte gene expression and differentiation. Fall-weaned Angus steers (n = 76; 258 ± 28 kg) were randomly assigned to 1 of 4 stocker production systems: 1) grazing dormant native range (NR) supplemented with a 40% CP cottonseed meal-based supplement (1.02 kg · steer^-1 · d^-1) followed by long-season summer grazing (CON, 0.46 kg/d); 2) grazing dormant NR supplemented with a ground corn and soybean meal-based supplement fed at 1% of BW followed by short-season summer grazing (CORN, 0.61 kg/d); 3) grazing winter wheat pasture (WP) at high stocking density (3.21 steers/ha) to achieve a moderate rate of gain (LGWP, 0.83 kg/d); and 4) grazing winter WP at low stocking density (0.99 steers/ha) to achieve a high rate of gain (HGWP, 1.29 kg/d). At the end of the stocker (intermediate harvest, IH) and finishing (final harvest, FH) phases, 4 steers / treatment were harvested and longissimus muscles (LM) sampled for cryohistological immunofluorescence analysis and SC culture assays. At IH, WP steers had greater LM fiber cross-sectional area than NR steers; however, at FH, the opposite was observed (p < 0.0001). At IH, CORN steers had the lowest Myf-5+:Pax7+ SC density (p = 0.020), while LGWP steers had the most Pax7+ SC (p = 0.043). At FH, CON steers had the highest LM capillary density (p = 0.003) and their cultured SC differentiated more readily than all other treatments (p = 0.017). At FH, Pax7 mRNA was more abundant in 14 d-old SC cultures from HGWP cattle (p = 0.03). Preadipocytes exposed to culture media from proliferating SC cultures from WP cattle isolated at FH had more PPARγ (p = 0.037) and less FABP4 (p = 0.030) mRNA expression compared with NR cattle. These data suggest that different stocker management strategies can impact skeletal muscle growth, SC function, and potentially impact marbling development in growing-finishing beef cattle.

The Social Construction of the Long-Term Athlete Development Framework

Mathew Dowling,Marvin Washington 글로벌지식마케팅경영학회 2021 Journal of Global Sport Management Vol.6 No.2

This article examines the social construction of the Long-Term Athlete Development (LTAD) framework and the Canadian Sport for Life Leadership Team (now Sport for Life), the group responsible for the creation, development and promotion of LTAD. In particular, the study draws upon Schneider and Ingram’s theory of social construction and policy design and empirical data collected from the leadership team and senior civil servants to trace the socio-political developments that have led to the emergence and development of the LTAD framework and the leadership team within Canadian sport. The analysis focuses on the role of government (via Sport Canada) and how the LTAD framework and the leadership team emerged from and attempted to influence the Canadian sport policy process. The findings reveal how the adoption of the LTAD framework can, in part, be explained by the socio-political developments or ‘politicking’ that occurred within and around the creation, development and dissemination of the framework itself. More broadly, the study explains how the LTAD framework has become an increasingly orthodox conception of the athlete development process despite the absence of scientific research to support many of its claims.

Quantitative Definitions of Collaborative Research Fields in Science and Engineering

Mathew Schwartz,박귀순,이성종 아시아기술혁신학회 2016 Asian Journal of Innovation and Policy Vol.5 No.3

Practical methodology for categorizing collaborative disciplines or research in a quantitative manner is presented by developing a Correlation Matrix of Major Disciplines (CMMD) using bibliometric data collected between 2009 and 2014. First, 21 major disciplines in science and engineering are defined based on journal publication frequency. Second, major disciplines using a comparing discipline correlation matrix is created and correlation score using CMMD is calculated based on an analyzer function that is given to the matrix elements. Third, a correlation between the major disciplines and 14 research fields using CMMD is calculated for validation. Collaborative researches are classified into three groups by partially accepting the definition of pluri-discipline from peer review manual, European Science Foundation, inner-discipline, inter-discipline and cross-discipline. Applying simple categorization criteria identifies three groups of collaborative research and also those results can be visualized. Overall, the proposed methodology supports the categorization for each research field.
