Relativistic Wigner Function for Quantum WalksAbstract
A relativistic Wigner function for free Discrete Time Quantum Walks (DTQWs) on the square 2D space-time lattice is defined. The transport equation obeyed by the relativistic Wigner function is derived in terms of discrete derivatives and degenerates in the continuum limit into the transport equation obeyed by the Wigner function of 2D Dirac fermions. The first corrections to the continuous equation induced by the discreteness of the lattice are also determined and the similarities with non-quantum relativistic tran [...] 1797 12257 |
A Rechargeable Aqueous Lithium-Air Battery with an Acetic Acid Catholyte Operated at High Pressureby
Abstract
Acidic aqueous lithium-air batteries are attractive candidates for use as energy sources in electric vehicles because of their high energy and power densities and ability to operate under ambient conditions. An aqueous lithium-air battery with an acetic acid catholyte has a high theoretical energy density of 1,478 Wh kg-1, and the reaction product is soluble in the catholyte. In this study, we have studied the cell performance of a Li/interlayer electrolyte/NASICON-type solid lithium-ion conductor/acetic acid catho [...] 1563 12251 |
Healthcare Provider’s Guide to Kratom: Succinct Introduction to the Basics and the QuestionsAbstract
Background: The leaves of Mitragyna speciosa (kratom), a tropical tree that is indigenous to Southeast Asia, have been used traditionally to increase stamina, as a digestive aid, and as an analgesic. Kratom use is now increasingly popular in the rest of the world because of easy availability through the Internet and real, or perceived, views of efficacy and safety. Methods: PubMed and MedLine searches were conducted of published articles available in English. Results: Mitragynine and 7-hydroxymitragynine are the pr [...] 1870 12249 |
Evaluation of Recent Statistical Methods for Detecting Differential Methylation Using BS-seq DataAbstract
Whole genome profiling of differential DNA methylation between diseased and normal samples has significant implications in research to understand the role of epigenetic regulations of cells. In recent years, the development of bisulfite sequencing (BS-seq)-based molecular technology has enabled the measurement of DNA methylation at a nucleotide resolution throughout the genome. Given the availability of this new type of DNA methylation data, certain features challenge traditional analytical methods such as the Fish [...] 2264 12241 |
The Impact of Stress on Father Involvement in Early Infancy: Examining Risk and Protective Factors in Residential and Nonresidential Fathersby
Abstract
Residential and nonresidential fathers are taking an increasingly greater role in their children’s lives, and father involvement predicts positive child outcomes across development. This study utilized data from a large sample of racially and ethnically diverse fathers of low to middle income (n = 1,112) to test if paternal stress is associated with lower father involvement in early infancy and whether perceived social support is protective. Exploratory analyses examined whether the effects of stress on father invo [...] 1368 12238 |
Expressive Arts for Grieving Youth: A Pilot ProjectAbstract
The experience of loss due to death, illness, and social mitigation was inevitable during the COVID-19 pandemic. Mental health services are chronically difficult to access in Canada, and this barrier is further exacerbated when trying to access certified art therapists to deliver expressive arts therapy. This pilot project attempted to provide an alternative to this service through an interprofessional alliance with a professional artist and certified counselors. A small group (n = 6) of vulnerable youth who had su [...] 2408 12226 |
Normalized Difference Vegetative Index-related Assessment for Climate Change Impact on Indigenous Communities from High Resolution IKONOS Satellite Imagery in West PapuaAbstract
High-resolution satellite imagery permits acquisition of critical data to observe climate-change and environmental impact on conflict-impacted indigenous communities with co-existing socio-economic factors, often within unstable regimes. Conflict may prevent direct access in remote regions to validate civilian conflict actor evidence. In such cases use of remote sensing tools, techniques, and data are extremely important. Software-based imagery assessment can quantify radiometrically calibrated or Normalized Differ [...] 1746 12223 |
Tuberculosis Screening and Treatment in Solid Organ TransplantationAbstract
Background: Tuberculosis (TB) is a common infection with challenges in diagnosis and treatment. Management of TB in solid organ transplant (SOT) candidates and recipients poses unique challenges not seen in other populations. Questions and Recommendations: Latent TB infection (LTBI) is important to diagnose pre-transplant through history, physical examination, imaging, and laboratory tests. Tuberculin skin tests and interferon-gamma release assays are important tools but not sufficiently sensitive nor specific to d [...] 1595 12220 |
Role of DNA Damage and MMP Loss in Radiosensitization-Induced Apoptosis by Ellagic Acid in HeLa CellsAbstract
Ellagic acid (EA) is a polyphenol found in grapes, pomegranates, walnuts, etc. exhibits anti-cancer properties. The current study was conducted to understand the radiosensitizing role of EA on HeLa cells. Monotherapy of EA and radiation was initially studied on HeLa cells. The addition of EA before the radiation treatment subsequently made DNA more susceptible to damage thereby developing DNA beaks, which are known to be lethal for cell survival. This was evaluated by performing comet and γ-foci formation ass [...] 1529 12217 |

Open Access Short Communication Gut Microbiota Potentiates the Effect of Immune Checkpoint Therapy against CancersAbstract
Immune checkpoints have been aggressively investigated for anti-cancer immunotherapy. The power of microbiota on the outcome of this immunotherapy has attracted much attention. For example, intestinal microorganisms play a key role in the effectiveness of programmed cell death 1 (PD1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA4) blockade. Additionally, short-chain fatty acids produced in the gut may modulate anti-CTLA4 and anti-PD1 stimulated immune responses and their anti-tumor efficacy. Enhancing the [...] 1425 12217 |
