Abstract
With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a detailed analysis of both triggered and serendipitous observations of 17 gravitational-wave (GW) events (7 triggered and 10 purely serendipitous) from the Searches After Gravitational-waves Using ARizona Observatories (SAGUARO) program. We searched a total of 4935 deg2 down to a median 5σ transient detection depth of 21.1 AB mag using the Mt. Lemmon 1.5 m telescope, the discovery engine for SAGUARO. In addition to triggered events within 24 hr, our transient search encompassed a time interval following GW events of <120 hr, providing observations on ∼1/2 of the events accessible to the Mt. Lemmon 1.5 m telescope. We covered 2.1%–86% of the LVC total probability (P
total) for individual events, with a median P
total ≈ 8% within <120 hr. Following improvements to our pipeline and the addition of serendipitous observations, we find a total of seven new optical candidates across five GW events, which we are unable to rule out after searching for additional information and comparing to kilonova models. Using both publicly available and our own late-time data, we investigated a total of 252 optical candidates for these 17 events, finding that only 65% were followed up in some capacity by the community. Of the total 252 candidates, we are able to rule out an additional 12 previously reported counterpart candidates. In light of these results, we discuss lessons learned from the SAGUARO GW counterpart search. We discuss how community coordination of observations and candidate follow-up, as well as the role of archival data, are crucial to improving the efficiency of follow-up efforts and preventing unnecessary duplication of effort with limited electromagnetic resources.

Rationing of Electricity in Maputo City Residences through Education and Awareness Actions
Authors: M A Chapala Nelson 
Published: May 2021

The level of rational use of electricity consumption by households in Mozambique is very low. This paper assesses whether, with the implementation of education and awareness actions through the door-to-door method, is possible to change the consumption habits and rationalize residential electricity consumption in Maputo city, Mozambique. The data was collected through questionnaires, observations, and interviews related to the habits of electricity consumption, the use of electrical equipment, and consumption of household appliances. This was followed by awareness creation on the use of electricity. The results show that after the campaign, the level of knowledge of the measures of rational use of electricity by consumers was increased by 55.3%, the level of adoption of the measures learned was increased by 30.5% and the monthly household consumption was decreased by 16.8%. Household consumption depends on the electrical equipment, and replacement of at least one 60W incandescent lamp in each residence with a 15W fluorescent lamp could bring a significant reduction in energy consumption. For example, the annual consumption of each family can be reduced by 94KWh and 23GWh in the entire City. The low level of rational use of electricity in Maputo city is due to lack of knowledge of the measures and little adoption of the known measures, use of inefficient equipment, low availability of the efficient equipment in the local markets, high cost of efficient technologies, and houses that offer few opportunities for rationing.

Deep Tissue Massage
Authors: Johnson Jane 
Published: May 2021

Many clients enjoy the sensation of deep tissue massage. Yet some therapists shy away from incorporating this form of massage into their treatments, believing it to require the application of force greater than what they can deliver. Or they are anxious about how to apply pressure safely.
Deep Tissue Massage describes how to use 83 compressive and stretching techniques in ways that are safe and effective for you and your clients. The reference contains step-by-step guidelines and over 165 color photos, which will help you deliver comfortable and satisfying massages to your clients. The techniques are organized by the part of the body being massaged (trunk, lower limbs, and upper limbs) and by the positioning of the client (three-quarter lying, supine, prone, and seated). Once you have learned about the techniques, you will then learn about incorporating them into effective routines by moving the client from one position to the next. Discover those techniques and treatment positions that appeal to you, and discard those that you find less helpful. You will find many of these techniques easy to apply and will quickly be able to include them as part of your practice.
Deep Tissue Massage explains techniques for avoiding overuse of your hands by incorporating the forearms, fists, and elbows. Throughout the book Client Talk boxes present tips for effective dialogue between therapist and client to ensure expectations are met and the client's limits for handling deep pressure are not exceeded. A photo gallery index provides a quick reference for treatment ideas or for checking technique.
Whether you are new to massage or a therapist with many years of experience, Deep Tissue Massage will be a great companion resource. Novices will love the easily accessible language and organization of this book, while veteran therapists will check technique and add variety to existing treatment routines. If used in a classroom setting, this book can stimulate debate and discussion about the proper use of deep tissue massage.

Published: May 2021

Abstract
The Katiniq ultrabasic sill was intruded as a liquid-crystal mixture. Cumulus silicate minerals accumulated at the center of a flow system. More dense cumulus sulfide liquid accumulated near the bottom of the sill and collected in riffle-shaped traps to form ore bodies.
The igneous series in the Cape Smith-Wakeham Bay belt of the Ungava peninsula rose through the crust along the boundary between the Churchill and Superior structural provinces of the Canadian shield. The composition of the series is contrasted with other magma series.
The ultrabasic rocks in the Bucko and Bowden deposits of the Manitoba (Thompson) nickel belt were intruded as a crystal mush with a much lower liquid content than that of the Katiniq sill. Silicate and sulfide phases show little evidence of gravity settling. Post-ultrabasic granitic intrusions cause extensive metasomatism of major elements but ore elements are not materially affected.
The McWatters, Ontario deposit, in a volcanic environment was intruded as a liquid-crystal mush with enough liquid to allow segregation of cumulus olivine toward the center of a dike flow-system, and gravity settling of cumulus sulfide liquid.
Single Semi‐Metallic Selenium Atoms on Ti3C2 MXene Nanosheets as Excellent Cathode for Lithium–Oxygen Batteries

Published: May 2021

AbstractRechargeable Li–O2 batteries are promising due to their superior high energy density but subject to sluggish oxygen reduction/evolution kinetics. Developing highly efficient catalysts to improve catalytic activity and alleviate oxidation–reduction overpotential of Li–O2 batteries is of great challenge and importance. Herein, a CO2‐assisted thermal‐reaction strategy is developed to fabricate isolated semi‐metallic selenium single‐atom‐doped Ti3C2 MXene catalyst (SASe‐Ti3C2) as cathodes for high‐performance Li–O2 batteries. The isolated moieties of single Se atom catalysis centers can function as active catalytic centers to drastically enhance the intrinsic LiO2‐absorption ability and thus fundamentally modulate the formation/decomposition mechanism of lithium peroxide (Li2O2) discharge product, thus demonstrating greatly enhanced redox kinetics and efficiently ameliorated overpotentials. Theoretical simulations reveal that the interaction between Se‐involved moieties and Ti3C2 substrate greatly enhances the intrinsic LiO2‐absorption ability and fundamentally promotes the charge transfer between electrode and Li2O2 product, deeply ameliorating the round‐trip overpotential. The well‐designed SASe–Ti3C2 electrode exhibits decreased charge/discharge polarization (1.10 V vs Li/Li+), ultrahigh discharge capacity (17 260 mAh g−1 at 100 mA g−1), and superior durability (170 cycles at 200 mA g−1) as cathode for Li–O2 batteries. The promising results will shed light on the design of highly efficient catalysts for oxygen‐involved systems of future investigation.

AbstractThe pandemic of coronavirus disease 2019 (COVID‐19) is continually worsening. Clinical treatment for COVID‐19 remains primarily supportive with no specific medicines or regimens. Here, the development of multifunctional alveolar macrophage (AM)‐like nanoparticles (NPs) with photothermal inactivation capability for COVID‐19 treatment is reported. The NPs, made by wrapping polymeric cores with AM membranes, display the same surface receptors as AMs, including the coronavirus receptor and multiple cytokine receptors. By acting as AM decoys, the NPs block coronavirus from host cell entry and absorb various proinflammatory cytokines, thus achieving combined antiviral and anti‐inflammatory treatment. To enhance the antiviral efficiency, an efficient photothermal material based on aggregation‐induced emission luminogens is doped into the NPs for virus photothermal disruption under near‐infrared (NIR) irradiation. In a surrogate mouse model of COVID‐19 caused by murine coronavirus, treatment with multifunctional AM‐like NPs with NIR irradiation decreases virus burden and cytokine levels, reduces lung damage and inflammation, and confers a significant survival advantage to the infected mice. Crucially, this therapeutic strategy may be clinically applied for the treatment of COVID‐19 at early stage through atomization inhalation of the NPs followed by NIR irradiation of the respiratory tract, thus alleviating infection progression and reducing transmission risk.

Authors: Ahmad Sarwat Asma Ziya , Jena Tapan Kumar , Khan Faiz Ahmed 
Published: May 2021

AbstractAlkyl enol ethers (AEE) are versatile synthetic intermediates with a unique reactivity pattern. This review article summarizes the synthesis of AEE as well as its reactivity and how enol ether undergoes intermolecular reactions for various bond formation, leading to the construction of several useful organic molecules. The synthetic applications of alkyl enol ethers towards intermolecular bond‐forming reactions include metal‐catalyzed reactions, cycloaddition and heterocycle formation as well as rwactions in the field of natural products synthesis. The achievement of these impressive transformations prove the countless synthetic potential of AEE. The main objective of this review is to bring attentiveness among synthetic chemists to show how AEE extensively can be used to react with both electrophiles as well as nucleophiles, thereby behaving as an ambiphilic reactant. We trust that the unique reactivity pattern of alkyl enol ethers and the fundamental mechanistic idea can attract chemists in AEE chemistry. Exclusively, intermolecular reactions of AEE with other functionalized moieties have not been reviewed to the best of our knowledge.

AbstractIntroductionYoung cancer survivors may be at increased risk of early‐onset chronic health conditions. The aim of this population‐based study is to estimate cardiovascular disease (CVD) risk among younger versus older B‐cell non‐Hodgkin's lymphoma (B‐NHL) survivors compared with their respective general population cohorts.MethodsB‐NHL survivors diagnosed from 1997 to 2015 in the Utah Cancer Registry were matched with up to five cancer‐free individuals on birth year, sex, and birth state, using the statewide Utah Population Database. Electronic medical records and statewide health care facility data were used to identify disease outcomes ≥5 years after cancer diagnosis. Cox Proportional Hazards models were used to estimate hazard ratios for B‐NHL survivors diagnosed at <65 years and ≥65 years old.ResultsYounger B‐NHL survivors had higher relative risks than older cancer survivors of chronic rheumatic disease of the heart valves (HR = 4.14, 99% CI = 2.17–7.89; P valueheterogeneity = 0.004); peri‐, endo‐, and myocarditis (HR = 2.43, 99% CI = 1.38–4.28; P valueheterogeneity = 0.016); diseases of the arteries (HR = 1.63, 99% CI = 1.21–2.21; P valueheterogeneity = 0.044); and hypotension (HR = 2.44, 99% CI = 1.58–3.75; P valueheterogeneity = 0.048). B‐NHL survivors of both age groups had elevated relative risks of heart disease overall and congestive heart failure.ConclusionYounger B‐NHL survivors had higher risks than older B‐NHL survivors of specific cardiovascular diseases compared to their respective general population cohorts.

AbstractSevere acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) poses a serious threat to healthcare systems worldwide. Binding of the virus to angiotensin‐converting enzyme 2 (ACE2) is an important step in the infection mechanism. However, it is unknown if ACE2 expression in patients with chronic lung diseases (CLDs), such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary arterial hypertension (IPAH), or pulmonary fibrosis (PF), is changed as compared to controls. We used lung samples from patients with COPD (n = 28), IPAH (n = 10), and PF (n = 10) as well as healthy control donor (n = 10) tissue samples to investigate the expression of ACE2 and related cofactors that might influence the course of SARS‐CoV‐2 infection. Expression levels of the ACE2 receptor, the putative receptor CD147/BSG, and the viral entry cofactors TMPRSS2 (transmembrane serine protease 2), EZR, and FURIN were determined by quantitative PCR and in open‐access RNA sequencing datasets. Immunohistochemical and single‐cell RNA sequencing (scRNAseq) analyses were used for localization and coexpression, respectively. Soluble ACE2 (sACE2) plasma levels were analyzed by enzyme‐linked immunosorbent assay. In COPD as compared to donor, IPAH, and PF lung tissue, gene expression of ACE2, TMPRSS2, and EZR was significantly elevated, but circulating sACE2 levels were significantly reduced in COPD and PF plasma compared to healthy control and IPAH plasma samples. Lung tissue expressions of FURIN and CD147/BSG were downregulated in COPD. None of these changes were associated with changes in pulmonary hemodynamics. Histological analysis revealed coexpression of ACE2, TMPRSS2, and Ezrin in bronchial regions and epithelial cells. This was confirmed by scRNAseq analysis. There were no significant expression changes of the analyzed molecules in the lung tissue of IPAH and idiopathic PF as compared to control. In conclusion, we reveal increased ACE2 and TMPRSS2 expression in lung tissue with a concomitant decrease of protective sACE2 in COPD patients. These changes represent the possible risk factors for an increased susceptibility of COPD patients to SARS‐CoV‐2 infection.
Variation in developmental rates is not linked to environmental unpredictability in annual killifishes

Published: May 2021

AbstractComparative evidence suggests that adaptive plasticity may evolve as a response to predictable environmental variation. However, less attention has been placed on unpredictable environmental variation, which is considered to affect evolutionary trajectories by increasing phenotypic variation (or bet hedging). Here, we examine the occurrence of bet hedging in egg developmental rates in seven species of annual killifish that originate from a gradient of variation in precipitation rates, under three treatment incubation temperatures (21, 23, and 25°C). In the wild, these species survive regular and seasonal habitat desiccation, as dormant eggs buried in the soil. At the onset of the rainy season, embryos must be sufficiently developed in order to hatch and complete their life cycle. We found substantial differences among species in both the mean and variation of egg development rates, as well as species‐specific plastic responses to incubation temperature. Yet, there was no clear relationship between variation in egg development time and variation in precipitation rate (environmental predictability). The exact cause of these differences therefore remains enigmatic, possibly depending on differences in other natural environmental conditions in addition to precipitation predictability. Hence, if species‐specific variances are adaptive, the relationship between development and variation in precipitation is complex and does not diverge in accordance with simple linear relationships.
