A simpler and more realistic subjective decision theory

In his classic book “the Foundations of Statistics” Savage develops a formal system of rational decision making. It is based on (i) a set of possible states of the world, (ii) a set of consequences, (iii) a set of acts, which are functions from states to consequences, and (iv) a preference relation over the acts, which represents the preferences of an idealized rational agent. The ...

Promoting cross-border knowledge transfer for new product development in MNCs: a process view

Cross-border knowledge transfer plays an important role in the competitive advantage of multinational corporations (MNCs). However, it can be quite challenging due to cultural differences and lack of trust between organizational units located in different countries. Prior studies have not explored the knowledge transfer process (and its key nodes) in new product development in ...

Topographical factor-based shallow landslide hazard assessment: a case of Dayi area of Guizhou Province in China

Background Three groups of factors related to topography, geology and hydrology have influence on the triggering of shallow landslides in soil material. In this paper a single representative factor (T-factor) for the topography is proposed, which can be used to define threshold values for the possibility of shallow soil slides. This study was carried out in the Dayi area, Guizhou ...

Bounded gaps between products of distinct primes

Let \(r \ge 2\) be an integer. We adapt the Maynard–Tao sieve to produce the asymptotically best-known bounded gaps between products of r distinct primes. Our result applies to positive-density subsets of the primes that satisfy certain equidistribution conditions. This improves on the work of Thorne and Sono.

A novel method for the detection of R-peaks in ECG based on K-Nearest Neighbors and Particle Swarm Optimization

Cardiovascular diseases are associated with high morbidity and mortality. However, it is still a challenge to diagnose them accurately and efficiently. Electrocardiogram (ECG), a bioelectrical signal of the heart, provides crucial information about the dynamical functions of the heart, playing an important role in cardiac diagnosis. As the QRS complex in ECG is associated with ...

Proteomic analysis of early salt stress responsive proteins in alfalfa roots and shoots

Alfalfa (Medicago sativa) is the most extensively cultivated forage legume in the world, and salinity stress is the most problematic environmental factors limiting alfalfa production. To evaluate alfalfa tissue variations in response to salt stress, comparative physiological and proteomic analyses were made of salt responses in the roots and shoots of the alfalfa. A two-dimensional ...

Peripheral immune tolerance alleviates the intracranial lipopolysaccharide injection-induced neuroinflammation and protects the dopaminergic neurons from neuroinflammation-related neurotoxicity

Neuroinflammation plays a critical role in the onset and development of neurodegeneration disorders such as Parkinson’s disease. The immune activities of the central nervous system are profoundly affected by peripheral immune activities. Immune tolerance refers to the unresponsiveness of the immune system to continuous or repeated stimulation to avoid excessive inflammation and ...

Deletion of Cdc42 in embryonic cardiomyocytes results in right ventricle hypoplasia

Background Cdc42 is a member of the Rho GTPase family and functions as a molecular switch in regulating cytoskeleton remodeling and cell polarity establishment. Inactivating Cdc42 in cardiomyocytes resulted in embryonic lethality with heart developmental defects, including ventricular septum defects and thin ventricle wall syndrome. Findings In this study, we have generated a Cdc42 ...

Optimizing Non-Decomposable Evaluation Metrics for Neural Machine Translation

While optimizing model parameters with respect to evaluation metrics has recently proven to benefit end to-end neural machine translation (NMT), the evaluation metrics used in the training are restricted to be defined at the sentence level to facilitate online learning algorithms. This is undesirable because the final evaluation metrics used in the testing phase are usually ...

A comparative study of the vibro-impact capsule systems with one-sided and two-sided constraints

nonlinearities increases, the dynamics of the system will become more complex from periodic motion to chaos. Acknowledgements Dr. Yang Liu would like to acknowledge the financial support from EPSRC for his First

Controlling multistability in a vibro-impact capsule system

This work concerns the control of multistability in a vibro-impact capsule system driven by a harmonic excitation. The capsule is able to move forward and backward in a rectilinear direction, and the main objective of this work is to control such motion in the presence of multiple coexisting periodic solutions. A position feedback controller is employed in this study, and our ...

Assessing medical professionalism: A systematic review of instruments and their measurement properties

Background Over the last three decades, various instruments were developed and employed to assess medical professionalism, but their measurement properties have yet to be fully evaluated. This study aimed to systematically evaluate these instruments’ measurement properties and the methodological quality of their related studies within a universally acceptable standardized framework ...

Analysis of novel RUNX2 mutations in Chinese patients with cleidocranial dysplasia

Cleidocranial dysplasia (CCD) is an autosomal dominant inheritable skeletal disorder characterized by cranial dysplasia, clavicle hypoplasia and dental abnormalities. This disease is mainly caused by heterozygous mutations in RUNX2, a gene that encodes an osteoblast-specific transcription factor. In the present study, mutational analyses of RUNX2 gene were performed on four ...
