Language acquisition and change are thought to be causally connected. We demonstrate a method for quantifying the strength of this connection in terms of the 'basic reproductive ratio' of linguistic constituents. It represents a standardized measure of reproductive success, which can be derived both from diachronic and from acquisition data. By analyzing phonotactic English data, we show that the results of both types of derivation correlate, so that phonotactic acquisition indeed predicts phonotactic change, and vice versa...

Although home visiting has been used in many populations in prevention efforts, the impact of scaled-up home-visiting programs on abuse and neglect remains unclear. The objective of this study was to assess the impact of voluntary participation in an established statewide home-visiting program for socially high-risk families on child maltreatment as identified by Child Protective Services (CPS). Propensity score matching was used to compare socially high-risk families with a child born between January 1, 2008 and December 31, 2011 who participated in Connecticut's home-visiting program for first-time mothers and a comparison cohort of families who were eligible for the home-visiting program but did not participate...

Nowadays, chemical catalytic methods for the treatment of organic wastes are attracting more and more research attention. In the current research, novel catalysts with palladium nanoparticles (Pd NPs) supported on the hollow mesoporous silica nanotubes (h-mSiO2 ) were synthesized for the catalytic reduction of 4-nitrophenol (4-NP) and hydrodechlorination (HDC) of 4-chlorophenol (4-CP). The key point for the fabrication of the catalysts is that a certain thickness of the silica shell was wrapped on the multiwalled carbon nanotubes (MWNTs) or Pd/MWNTs through biphase stratification approach, and then the samples were calcined to remove the MWNTs...

BACKGROUND: Atypical meningiomas are common central nervous system neoplasms with high recurrence rate and poorer prognosis compared to their grade I counterparts. Surgical excision and radiotherapy remains the mainstay therapy but medical treatments are limited. We explore new drug candidates using computational drug repurposing based on the gene expression signature of atypical meningioma tissue with subsequent analysis of drug-generated expression profiles. We further explore possible mechanisms of action for the identified drug candidates using ingenuity pathway analysis (IPA)...

Most coral-associated decapod species have non-migratory adult populations and depend on their planktonic larvae for dispersal. This study examined the metapopulation structure of three decapod species with different pelagic larval duration (PLD) from twelve coral reef complexes of the Gulf of Mexico. The dispersion of larvae was analyzed through the use of a realistic numerical simulation of the Gulf of Mexico with the Hybrid Coordinate Ocean Model. To study the transport and dispersion of particles in near-surface waters, a particle-tracking subroutine was run using as input the currents from the model...

Multiplex networks describe a large number of complex social, biological and transportation networks where a set of nodes is connected by links of different nature and connotation. Here we uncover the rich community structure of multiplex networks by associating a community to each multilink where the multilinks characterize the connections existing between any two nodes of the multiplex network. Our community detection method reveals the rich interplay between the mesoscale structure of the multiplex networks and their multiplexity...

BACKGROUND: While the high prevalence of preterm births and its impact on infant mortality in the US have been widely acknowledged, recent data suggest that even full-term births in the US face substantially higher mortality risks compared to European countries with low infant mortality rates. In this paper, we use the most recent birth records in the US to more closely analyze the primary causes underlying mortality rates among full-term births. METHODS AND FINDINGS: Linked birth and death records for the period 2010-2012 were used to identify the state- and cause-specific burden of infant mortality among full-term infants (born at 37-42 weeks of gestation)...

Multi-robot teams composed of ground and aerial vehicles have gained attention during the last few years. We present a scenario where both types of robots must monitor the same area from different view points. In this paper, we propose two Lloyd-based tracking strategies to allow the ground robots (agents) to follow the aerial ones (targets), keeping the connectivity between the agents. The first strategy establishes density functions on the environment so that the targets acquire more importance than other zones, while the second one iteratively modifies the virtual limits of the working area depending on the positions of the targets...

Timing points used in running races and other competition events are generally based on radio-frequency identification (RFID) technology. Athletes' times are calculated via passive RFID tags and reader kits. Specifically, the reader infrastructure needed is complex and requires the deployment of a mat or ramps which hide the receiver antennae under them. Moreover, with the employed tags, it is not possible to transmit additional and dynamic information such as pulse or oximetry monitoring, alarms, etc. In this paper we present a system based on two low complex schemes allowed in Bluetooth Low Energy (BLE): the non-connectable undirected advertisement process and a modified version of scannable undirected advertisement process using the new capabilities present in Bluetooth 5...

Flexible sensors connected to cell phones are a promising technology that can aid in continuously monitoring signals in our daily lives, such as an individual's health status and information from buildings, farms, and industry. Among such signals, real-time humidity monitoring is crucial to a comfortable life, as human bodies, plants, and industrial environments require appropriate humidity to be maintained. We propose a hydrophilic polytetrafluoroethylene (H-PTFE)-based flexible humidity sensor integrated with readout circuitry, wireless communication, and a mobile battery...

A sharp drop in physical activity and skyrocketing obesity rate has accompanied rapid urbanization in China. The urban planning concept of transit-oriented development (TOD) has been widely advocated in China to promote physical activity, especially walking. Indeed, many design features thought to promote walking-e.g., mixed land use, densification, and well-connected street network-often characterize both TODs and established urban neighborhoods. Thus, it is often assumed that TODs have similar physical activity benefits as established urban neighborhoods...

Systemic sclerosis (SSc) is a multisystem connective tissue disease characterized by vascular damage with non-specific inflammation and progressive fibrosis. The disease exhibits a large heterogeneity in both clinical and serological features. This diversity refers to the course of the disease, which is difficult to predict in many cases. Although poor prognostic factors are well known, it is not always possible to predict the course of the disease and the prognosis. Furthermore, the activity of disease is difficult to assess since both reversible and irreversible lesions can occur in one patient...

The available data indicate that seropositive rheumatoid arthritis (RA) develops as a result of systemic, autoimmune reaction directed against a range of "self" peptides/proteins that have undergone specific forms of post-translational modification. The development and progress of autoimmunity may be triggered by non-specific, local inflammatory processes outside the joints, for example in the oral or respiratory mucous membrane. The disease occurs in genetically susceptible individuals under the influence of environmental risk factors that promote autoimmunity and consequently the inflammatory process...

Recognizing the antiphospholipid syndrome (APS) in patients with lupus (SLE) can be difficult and therefore underestimated. Detection of antiphospholipid antibodies (aPL) in each patient with SLE should be done as a rule. Introduction of the new classification criteria of this syndrome will certainly improve the recognition of APS in the future. The Sapporo APS classification criteria (1998) were replaced by the Sydney criteria in 2006. Based on the most recent criteria, classification with APS requires one clinical and one laboratory manifestation...

Patient engagement in health care decisions largely depends on a patient's health literacy and the health literacy attributes of the health care organization. Librarians have an established role in connecting patients with health information in the context of their care. However, librarians can play a larger role in helping to make changes in their organization's health literacy attributes. This article discusses one medical library's process of leading systematic assessment of their organization's health literacy attributes...

BACKGROUND: The pathogenesis of secondary Raynaud's phenomenon (SRP) associated with connective tissue diseases (CTD) is not entirely understood. Nervous system dysfunction and microangiopathy are considered to be causes of this pathology. OBJECTIVES: Peripheral and autonomic nervous system function, the stage of microangiopathy, and the relationships between these in patients with SRP were analyzed. MATERIAL AND METHODS: In the study, 20 patients with CTD-related SRP and 30 healthy controls were subject to capillaroscopy, standard conduction velocity tests and conduction velocity distribution (CVD) tests in ulnar and peroneal nerves, heart rate variability (HRV), and sympathetic skin response (SSR) tests...

BACKGROUND: Periodontitis is a major risk factor of systemic diseases with inflammatory etiology. Numerous studies have established the connection between periodontal condition and diabetes, but there are no reports in the literature on the relationship between periodontitis and other pancreas conditions. The activity of pancreatic enzymes is an important parameter of pancreatic damage, and is also a diagnostic marker of acute and chronic pancreatitis, and the bleeding index determines the periodontitis activity...
