Electromagnetic radiowave exposure is a major concern in most countries due to possible adverse health effects. Over the last 10years, many technological changes (digital television, mobile technologies, wireless networks…) have led to variations in the electromagnetic field (EMF) levels. A large number of studies devoted to the analysis of EMF levels with personal dosimeters or computer models of the exposure of mobile stations have been conducted. However, the study of the exposure values, taking into account all the existing sources, and their evolution in a wide area, using measurements, has rarely been performed...

The application of advanced sequencing technologies and the rapid growth of various sequence data have led to increasing interest in DNA sequence assembly. However, repeats and polymorphism occur frequently in genomes, and each of these has different impacts on assembly. Further, many new applications for sequencing, such as metagenomics regarding multiple species, have emerged in recent years. These not only give rise to higher complexity but also prevent short-read assembly in an efficient way. This article reviews the theoretical foundations that underlie current mapping-based assembly and de novo-based assembly, and highlights the key issues and feasible solutions that need to be considered...

Augmented, virtual, and mixed reality applications all aim to enhance a user's current experience or reality. While variations of this technology are not new, within the last few years there has been a significant increase in the number of artificial reality devices or applications available to the general public. This column will explain the difference between augmented, virtual, and mixed reality and how each application might be useful in libraries. It will also provide an overview of the concerns surrounding these different reality applications and describe how and where they are currently being used...

As technology becomes ubiquitous in designing and delivering medical school curricula, health sciences librarians can embrace emerging opportunities for participation in curriculum design. A new medical librarian at Michigan State University Libraries engaged her user base outside of established duties, learned new skills, and challenged preconceived notions about librarians' roles. In the process, she became a partner in copyright education, amended license agreements for enhanced curricular multimedia use, and facilitated curriculum mapping through taxonomy building...

This column describes the approaches taken by librarians and staff at James Madison University (JMU) Libraries & Educational Technologies (LET) to extend library support to university athletics. The model resembles that used for outreach to academic programs and was first adapted to the semi-clinical, nonacademic Strength & Conditioning Department, then to JMU Athletics as a whole. Librarians offered targeted instructional sessions, orientations, and asynchronous learning modules embedded in the learning management system...

The emerging genome editing technology has enabled the creation of gene knock-in cells easily, efficiently, and rapidly, which has dramatically accelerated research in the field of mammalian functional genomics, including in humans. We recently developed a microhomology-mediated end-joining-based gene knock-in method, termed the PITCh system, and presented various examples of its application. Since the PITCh system only requires very short microhomologies (up to 40 bp) and single-guide RNA target sites on the donor vector, the targeting construct can be rapidly prepared compared with the conventional targeting vector for homologous recombination-based knock-in...

PURPOSE: The home-based rehabilitation of elderly patients improves their autonomy, independence and reintegration into society. Hence, a suitable environment plays an important role in rehabilitation, as do different assistance technologies. The majority of accidents at home involving elderly people occur in the bathroom. Therefore, the planning of the layout of facilities is important in this potentially dangerous area. This paper proposes an approach towards designing and optimizing the layout of facilities in the bathroom, based on logistical and nonlogistical relationships...

Since the inception of critical care as a formal discipline in the late 1950s, we have seen rapid specialization to many types of intensive care units (ICUs) to accommodate evolving life support technologies and novel therapies in various disciplines of medicine. Indeed, the field has expanded such that specialized ICUs currently exist to address critical care problems in medicine, cardiology, neurology and neurosurgery, trauma, burns, organ transplant and cardiothoracic surgeries. Specialization does not only need new infrastructure, but also training and staffing of health care providers, ancillary staff, and development and implementation of processes of care...

Clinical neurosurgery has been practiced in the US capital for just over 100 years. As former residents and fellows of Drs. Harvey Cushing and Walter Dandy moved to the region, hospitals at Georgetown and George Washington Universities became early adopters of this new surgical discipline. Later academic neurosurgery programs were established at the National Institutes of Health, Walter Reed Medical Center, and Children's National Medical Center. Neurosurgical pioneers at these institutions developed new technologies and diagnostic procedures which continue to inform our current practice...

Long noncoding RNAs (lncRNAs) had been defined as a novel class of functional RNAs longer than 200 nucleotides around a decade ago. It is widely acknowledged that lncRNAs play a significant role in regulation of gene expression, but the biological and molecular mechanisms are diverse and complex, and remain to be determined. Especially, the regulatory network of lncRNAs associated with other biological molecules is still a controversial matter, thus becoming a new frontier of the studies on transcriptome. Recent advance in high-throughput sequencing technologies and bioinformatics approaches may be an accelerator to lift the mysterious veil...

Molecular profiling on the single-cell level helps unveil the mystery of gene expression patterns in individual cells at subcellular resolution, enabling discovery of small but meaningful variations that are often overlooked at the population level. Similar to other immunoassays, the most common and economical protocols are developed by combining primary antibodies (1'Abs) and fluorophore-labeled secondary antibodies (2'Abs). The selection of 1' and 2' Abs, however, has been limited by the availability of animal species, consequently resulting in low multiplexing capability...

The DNA Damage Response (DDR) has been extensively characterized in studies of double strand breaks (DSBs) induced by laser micro beam irradiation in live cells. The DDR to helix distorting covalent DNA modifications, including interstrand DNA crosslinks (ICLs), is not as well defined. We have studied the DDR stimulated by ICLs, localized by laser photoactivation of immunotagged psoralens, in the nuclei of live cells. In order to address fundamental questions about adduct distribution and replication fork encounters, we combined laser localization with two other technologies...

With the development of laser technology, laser-driven proton acceleration provides a new way for proton tumor therapy. However, it has not been applied in practice, because of the wide and decreasing energy spectrum of laser-accelerated proton beams. In this paper, we propose an analytical model to reconstruct the spread-out Bragg peak (SOBP) using the laser-accelerated proton beams. Firstly, we present a modified weighting formula for protons of different energies. Secondly, a theoretical model for the reconstruction of SOBPs with laser-accelerated proton beams has been built...

Many educational policies provide learners with more resources (e.g., new learning activities, study materials, or technologies), but less often do they address whether students are using these resources effectively. We hypothesized that making students more self-reflective about how they should approach their learning with the resources available to them would improve their class performance. We designed a novel Strategic Resource Use intervention that students could self-administer online and tested its effects in two cohorts of a college-level introductory statistics class...

Droplet motion arises in many natural phenomena, ranging from the familiar gravity-driven slip and arrest of raindrops on windows, to the directed transport of droplets for water harvesting by plants and animals under dry conditions. Delib-erate transportation and manipulation of droplets is also important in many technological applications, including drop-let-based microfluidic chemical reactors and for thermal management. Droplet motion usually requires gradients of sur-face energy or temperature, or external vibration to overcome contact angle hysteresis...

Jie Xia, Yuhao Cheng, Hang Zhang, Rutian Li, Yiqiao Hu, Baorui Liu
Adhesions between homologous cancer cells play an important role in promoting tumor progression and designing tumor-targeting methods. Known as "homologous adhesions" of cancerous cells, these are usually more specific than adhesions to normal cells and heterogenic cells, and they have been widely discovered both in vivo and in vitro. The aberrant expression of cell adhesion-related molecules (CARMs) on each species of cancer cells is mainly responsible for inducing more specific homologous adhesions. Based on the improvement of biomimetic technologies, such adhesion has been investigated and applied deeply in drug delivery systems recently...

Climate change and ocean acidification are altering marine ecosystems and, from a human perspective, creating both winners and losers. Human responses to these changes are complex, but may result in reduced government investments in regulation, resource management, monitoring and enforcement. Moreover, a lack of peoples' experience of climate change may drive some towards attributing the symptoms of climate change to more familiar causes such as management failure. Taken together, we anticipate that management could become weaker and less effective as climate change continues...

PURPOSE OF REVIEW: Membrane invaginations called t-tubules play an integral role in triggering cardiomyocyte contraction, and their disruption during diseases such as heart failure critically impairs cardiac performance. In this review, we outline the growing understanding of the malleability of t-tubule structure and function, and highlight emerging t-tubule regulators which may be exploited for novel therapies. RECENT FINDINGS: New technologies are revealing the nanometer scale organization of t-tubules, and their functional junctions with the sarcoplasmic reticulum called dyads, which generate Ca(2+) sparks...
