A novel piecewise water flow technique for text line extraction from multi-skewed document images of handwritten text of different scripts is presented here. The basic water flow technique assumes that the hypothetical water flows from both left and right sides of the image frame. This flow of water fills up the gaps between consecutive objects but faces obstruction if any object lies in the path of the flow. All unwetted regions in the document image are then labeled distinctly to extract (...) the text lines. However, the technique fails when two neighboring text lines touch each other, as water gets obstructed by the touching segment. To get rid of this difficulty, we have modified the basic water flow technique by iteratively applying the same over the vertically segmented document images. The main purpose of this vertical segmentation is to localize the text line segment where two text lines get joined. These segments are then horizontally fragmented, and each fragment is placed suitably to the text line in which it actually belongs to. This way, the probable data loss during isolation of the touching text line segment is minimized. Both the techniques have been tested on three different databases, viz., CMATERdb 1.1.1, CMATERdb 1.1.2, and ICDAR2009 handwritten segmentation contest pages, respectively. The test results show that the present technique outperforms the basic one for all three databases. (shrink)

In this paper, a novel approach for word extraction and character segmentation from the handwritten Bangla document images is reported. At first, a modified Run Length Smoothing Algorithm, called Spiral Run Length Smearing Algorithm, is applied for the extraction of words from the text lines of unconstrained handwritten Bangla document images. This technique has helped to overcome some of the drawbacks of standard horizontal and vertical RLSA techniques. SRLSA technique has been applied on the Bangla handwritten document image database CMATERdb1.1.1 (...) and the success rate of the word extraction is found to be 86.01%. In the second part of the work, we have presented a useful solution to the problem on how best word images of handwritten Bangla script can be segmented into constituent characters. Moreover, the technique can segment the words having discontinuity in Matra, a prominent feature of Bangla script. It also optimizes the trade-off between under/over segmentation as Matra region and segmentation points are estimated more precisely. As a result, better word segmentation accuracy is achieved with minimal data loss. Here, a success rate of 92.48% is observed on a dataset of 750 handwritten Bangla words which is 3.35% higher than that of our earlier techniques. (shrink)

The accurate annotation of an unknown protein sequence depends on extant data of template sequences. This could be empirical or sets of reference sequences, and provides an exhaustive pool of probable functions. Individual methods of predicting dominant function possess shortcomings such as varying degrees of inter-sequence redundancy, arbitrary domain inclusion thresholds, heterogeneous parameterization protocols, and ill-conditioned input channels. Here, I present a rigorous theoretical derivation of various steps of a generic algorithm that integrates and utilizes several statistical methods to predict (...) the dominant function in unknown protein sequences. The accompanying mathematical proofs, interval definitions, analysis, and numerical computations presented are meant to offer insights not only into the specificity and accuracy of predictions, but also provide details of the operatic mechanisms involved in the integration and its ensuing rigor. The algorithm uses numerically modified raw hidden markov model scores of well defined sets of training sequences and clusters them on the basis of known function. The results are then fed into an artificial neural network, the predictions of which can be refined using the available data. This pipeline is trained recursively and can be used to discern the dominant principal function, and thereby, annotate an unknown protein sequence. Whilst, the approach is complex, the specificity of the final predictions can benefit laboratory workers design their experiments with greater confidence. -/- . (shrink)

This study explores the impact of both individual ethics (IE) and organizational ethics (OE) on ethical intention (EI). Ethical intention, or the individual's intention to engage in ethical behavior, is useful as a dependent variable because it relates to behavior which can be an expression of values, but also is influenced by organizational and societal variables. The focus is on EI in international business decision-making, since the international context provides great latitude in making ethical decisions. Results demonstrate that both IE (...) and OE influence EL Ethical congruence is also discussed as a positive influence. Younger managers are more influenced by OE than older managers. The findings call for creating governance mechanisms to enhance ethical congruence, thereby increasing the likelihood of managers making ethical choices in organizational decision-making. (shrink)

Introduction: Intimate Partner Violence (IPV) has unfavorable consequences for women as well as for newborn babies, which is very serious and preventable public health problem. It is believed to have an excessive occurrence in lives of women in South Asia. The objective of this study is to describe the prevalence, risk factors and consequences of IPV in Bangladesh. Methods: A scoping review was carried out based on the past 12 years of posted and gray literature about IPV in Bangladesh using (...) Arksey and O’Malley’s framework. Only the literature addressing abuses or violence in households or outside including physical, sexual or mental violence on the married woman in Bangladesh were taken into consideration for the study. Results: The overall prevalence of IPV in Bangladesh, the latest reviews of rates ranging from 15.5-82.7%.Most of the IPV in Bangladesh was based totally on the experience of legally married women. The main risk factors of IPV in Bangladesh were women being younger, from lower socioeconomic reputation, from lower academic attainment and lower education of husband, dowry, child marriage, perceived disobedience of wives, family conflict, children had recently been ill, and incapability of to furnish sexual satisfaction. Maternal depressive symptoms, signs of stress, anxiety and constraint to the better health of young children are the main consequences of IPV in Bangladesh. Besides, IPV causes unwanted pregnancy, pregnancy loss in the form of miscarriage, induced abortion, or stillbirth and termination of pregnancy in Bangladesh. Conclusions: Woman’s empowerment may reduce IPV and understanding attitudes towards IPV in cultural context could be crucial for developing interventions to reduce IPV and its consequences. (shrink)

Although initiation of DNA replication is considered to be highly coordinated through multiple protein–DNA and protein–protein interactions, it is poorly understood how particular locations within the eukaryotic chromosome are selected as origins of DNA replication. Here, we discuss recent reports that present structural information on the interaction characteristics of the archaeal orthologues of the eukaryotic origin recognition complex with their cognate binding sequences.1,2 Since the archaeal replication system is postulated as a simplified version of the one in eukaryotes, by analogy, (...) these works provide insights into the functions of the eukaryotic initiator proteins.

The nature of the product to be discovered guides the reasoning to discover it. Biologists and medical researchers often search for mechanisms. The "new mechanistic philosophy of science" provides resources about the nature of biological mechanisms that aid the discovery of mechanisms. Here, we apply these resources to the discovery of mechanisms in medicine. A new diagrammatic representation of a disease mechanism chain indicates both what is known and, most significantly, what is not known at a given time, thereby guiding (...) the researcher and collaborators in discovery. Mechanisms of genetic diseases provide the examples. (shrink)

Social enterprises that operate in business-to-business contexts, often out of emerging economies, typically face high expectations from business clients, mainstream competition, and the challenge of operating across distances. In these contexts, social enterprises need to carefully choose which market segments to serve and how to organize their social mission accordingly. Based on the case of impact sourcing—hiring and training of disadvantaged staff for global business services—we seek to better understand this interplay. In general, we find that social enterprises in this (...) context focus on serving either domestic clients with an implicit social mission and an integrated social enterprise model or international clients with a more explicit social mission and a decoupled model. We discuss why both main configurations represent viable social enterprise models in the outsourcing industry, and why, in particular, the professional background of founders plays a key role in these strategic choices. Our findings contribute to a more nuanced and context-sensitive understanding of social enterprise model adoption in emerging economies. (shrink)

Predatory journals and conferences are an emerging problem in scientific literature as they have financial motives, without guaranteeing scientific quality and exposure. The main objective of the ASGLOS project is to investigate the predatory e‐email characteristics, management, and possible consequences and to analyse the extent of the current problem at each academic level. To collect the personal experiences of physicians’ mailboxes on predatory publishing, a Google Form® survey was designed and disseminated from September 2021 to April 2022. A total of (...) 978 responses were analysed from 58 countries around the world. A total of 64.8% of participants indicated the need for 3 or fewer emails to acquire a criticality view in distinguishing a real invitation from a spam, while 11.5% still have doubt regardless of how many emails they get. The AGLOS Study clearly highlights the problem of academic e‐mail spam by predatory journals and conferences. Our findings signify the importance of providing academic career‐oriented advice and organising training sessions to increase awareness of predatory publishing for those conducting scientific research.
