In this article, we turn back to the 1918 influenza pandemic to throw light on the alliances of information communication technologies and technologies of mobility (such as the car) during the pandemic. We examine newspaper articles, technical publications, and other historical texts to demonstrate that, despite the fact that mobile technologies-such as cellular phones-did not exist during the 1918 pandemic, the telephone and mobility technology nonetheless formed alliances as networks in motion, or social moments in which risk and reward are calculated not simply by the ability to move, but rather the ability to move, while remaining connected, revealing insight into early cultural formations that share similarities and differences with the use of modern mobile media and mobility technologies during the ongoing COVID-19 pandemic...

BACKGROUND: Caregivers of patients with hematologic malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) play a crucial role in supporting their loved ones through physical, emotional, and practical challenges. This role has been associated with high levels of psychological distress and low levels of positive psychological well-being (PPWB). Positive psychology interventions for caregivers in other disease groups (e.g., breast cancer) have been associated with improved outcomes...

Delivery of high-quality behavioral health (BH) care is essential to supporting the readiness of the U.S. armed forces and their families. The coronavirus disease 2019 (COVID-19) pandemic led to a dramatic expansion of virtual behavioral health (VBH) care: remote patient access to BH care using technology such as a computer or cellular phone. The U.S. Army asked RAND Arroyo Center to examine the use of VBH to inform recommendations on the role of VBH care in the future of BH care in the Military Health System...

The fifth-generation (5G) mobile cellular network is vulnerable to various security threats. Radio frequency fingerprint (RFF) identification is an emerging physical layer authentication technique which can be used to detect spoofing and distributed denial of service attacks. In this paper, the performance of RFF identification is studied for 5G mobile phones. The differential constellation trace figure (DCTF) is extracted from the physical random access channel (PRACH) preamble. When the database of all 64 PRACH preambles is available at the gNodeB (gNB), an index-based DCTF identification scheme is proposed, and the classification accuracy reaches 92...

Soil microbial fuel cells (SMFCs) are bioelectrical devices powered by the oxidation of organic and inorganic compounds due to microbial activity. Seven soils were randomly selected from Bergen Community College or areas nearby, located in the state of New Jersey, USA, were used to screen for the presence of electrogenic bacteria. SMFCs were incubated at 35-37 °C. Electricity generation and electrogenic bacteria were determined using an application developed for cellular phones. Of the seven samples, five generated electricity and enriched electrogenic bacteria...

Worldwide, insects are declining at an alarming rate. Among other causes, the use of pesticides and modern agricultural practices play a major role in this. Cumulative effects of multiple low-dose toxins and the distribution of toxicants in nature have only started to be investigated in a methodical way. Existing research indicates another factor of anthropogenic origin that could have subtle harmful effects: the increasingly frequent use of electromagnetic fields (EMF) from man-made technologies. This systematic review summarizes the results of studies investigating the toxicity of electromagnetic fields in insects...

Philippine clinical laboratory licensing requirements mandate that diagnostic microscopy for Tuberculosis (TB) sputum microscopy, urinalysis, pap smears, wet smears, an option for complete blood count, stool exams, and malaria thick and thin smears should be accessible and available in health facilities including primary care centers. However, access to these essential diagnostics is hampered by the lack of trained personnel, relatively high costs for supplies and equipment especially in rural and underserved areas...

The COVID-19 pandemic has accelerated the introduction of remote work as one way to ensure employee safety and reduce the amount of interpersonal contact while continuing business operations. Knowing the degree of prevalence of remote work and its establishment are considered to be important factors in future policies and urban planning. We applied non-negative matrix factorization to population-change data obtained from a mobile phone network to extract the component of working people, and analyzed the changes pre- and post-pandemic...

Understanding human use of public lands is essential for management of natural and cultural resources. However, compiling consistently reliable visitation data across large spatial and temporal scales and across different land managing entities is challenging. Cellular device locations have been demonstrated as a source to map human activity patterns and may offer a viable solution to overcome some of the challenges that traditional on-the-ground visitation counts face on public lands. Yet, large-scale applicability of human mobility data derived from cell phone device locations for estimating visitation counts to public lands remains unclear...

The coronavirus disease 2019 (COVID-19) pandemic and the measures taken by authorities to control its spread have altered human behavior and mobility patterns in an unprecedented way. However, it remains unclear whether the population response to a COVID-19 outbreak varies within a city or among demographic groups. Here, we utilized passively recorded cellular signaling data at a spatial resolution of 1 km × 1 km for over 5 million users and epidemiological surveillance data collected during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA...

The purpose of this study was to assess the assistive devices used by patients with IRDs, the difficulties they face despite these devices, and their recommendations for a future visual prosthesis. In collaboration with blind patients, an online survey was developed and administered to adults with IRDs and visual acuities of 20/400 to no light perception in the better-seeing eye...

INTRODUCTION: Rapid onsite evaluation (ROSE) decreases rates of inadequate fine-needle aspirations (FNAs). Telecytology allows pathologists to perform ROSE without being physically "on site", thereby saving cytopathologists' travel time and allowing them to perform ROSE for multiple institutions. Little research exists comparing telecytology to non-telecytology ROSE for FNA inadequacy rates. MATERIALS AND METHODS: Using previously obtained quality metrics, we compared inadequacy rates for lymph node and thyroid FNAs with and without ROSE and with non-telecytology ROSE compared with telecytology ROSE...

Cyberbullying has emerged as a societal issue, and the majority of the research examining cyberbullying perpetration samples adolescent and/or emerging adult populations. A paucity of empirical attention has focused on young children (aged 8-10) regarding their cyberbullying frequency and predictors. The current study sampled 142 US youth aged 8-10 years and assessed their cyberbullying perpetration rate and cellular phone ownership. Results indicated that (a) older participants were more likely to cyberbully than their younger peers; (b) higher rates of cyberbullying were found for youth who already owned a cellular phone; and (c) an interaction between participant age and cellular phone ownership was found, suggesting that cyberbullying was highest for only the 10-year-old group who owned a cellular phone...
