The copious photochemistry of 2,6‐diaminopurine: Luminescence, triplet population, and ground state recovery*
Authors: Oliveira Leonardo M. F. , Valverde Danillo , Costa Gustavo J. , Borin Antonio Carlos 
Published: July 2023

Abstract9H‐ and 7H‐2,6‐Diaminopurine (26DAP) photoinduced events in vacuum were studied at the MS‐CASPT2/cc‐pVDZ level of theory. The S1 1(ππ* La) state is initially populated evolving barrierless towards its minimum energy structure, from where two photochemical events can take place in both tautomers. The first is the return of the electronic population to the ground state via the C6 conical intersection (CI‐C6). The second involves an internal conversion to the ground through the C2 conical intersection (CI‐C2). According to our geodesic interpolated paths connecting the critical structures, the second route is less favorable in both tautomers, due to the presence of high energy barriers. Our calculations suggest a competition between fluorescence and ultrafast relaxation to the electronic ground state via internal conversion process. Based on our calculated potential energy surfaces and experimental excited state lifetimes from the literature, we can infer that the 7H‐ must have a greater fluorescence yield than the 9H‐tautomer. We also explored the triplet state population mechanisms on the 7H‐26DAP to understand their long‐lived components observed experimentally.
The biggest losers: Legacy, exigence, and apologia in presidential farewell addresses
Authors: Milford Mike 
Published: July 2023

AbstractCampbell and Jamieson and Medhurst's foundational works on presidential farewell addresses assert that the form creates a sense of continuity, progressive perfection, and pedagogical affirmation and adapts to personal and situational exigencies to define a personal and administrative legacy for the outgoing president, as evidenced by the oft‐celebrated addresses of Washington and Eisenhower. However, at times these constraints are difficult to manage, particularly in the case of incumbents who were soundly denied a second term because of questionable administrative choices. In such cases, rhetors often turn to generic hybrids, combining forms and functions of different addresses to attend to complicated exigencies and audiences. The cases considered here infused the farewell's form with apologia, a speech of self‐defense, resulting in an inward‐focused address that failed to resolve important legacies. Examining the farewell addresses of three of the biggest electoral losers in history provides insight into the impacts these choices have on presidential legacy.

AbstractBackgroundThe aim of this study was to determine the predictive role of series and parallel bioelectrical impedance‐derived parameters in predicting total body (TBW), intracellular (ICW), and extracellular water (ECW) in athletes.MethodsThis cross‐sectional study analyzed 134 male (21.33 ± 5.11 years) and 64 female (20.45 ± 5.46 years) athletes. Using dilution techniques, TBW and ECW were determined while ICW was the difference between both. Raw and standardized for height (/H) bioelectrical resistance (R), reactance (Xc), and impedance (Z) values were obtained using a phase‐sensitive device at a single frequency in a series array (s). These were mathematically transformed in a parallel array (p) and capacitance (CAP). Fat‐free mass (FFM) was assessed by dual‐energy X‐ray absorptiometry.ResultsMultiple regressions adjusted for age and FFM show that R/Hs, Z/Hs, R/Hp, and Z/Hp were significant predictors of TBW (p < 0.001 in females and males). While Xc/Hs did not predict ICW, Xc/Hp was a predictor (p < 0.001 in females and Males). In females, R/H and Z/H predicted similarly TBW, ICW, and ECW. In males, R/Hs was considered a better predictor than R/Hp for TBW and ICW, and the Xc/Hp was considered the best predictor for ICW. Another significant predictor of ICW was CAP (p < 0.001 in females and males).ConclusionThis study highlights the potential value of parallel bioelectrical impedance values to identify fluid compartments in athletes as an alternative to the regularly used series measurements. Moreover, this study supports Xc in parallel, and ultimately CAP, as valid indicators of cell volume.
Aggression as successful self‐control
Authors: Chester David S. 
Published: July 2023

AbstractA dominant narrative is that aggression starts when self‐control stops – unchecked aggressive impulses manifest in violence as self‐control fails to inhibit them. Yet this ‘low self‐control syndrome’ approach to aggression fails to accommodate numerous findings in which aggression arises from successful self‐control. I summarize these key findings while identifying how current theories of aggression can be molded to accommodate them. This balanced perspective, which allows aggression to arise from successful and unsuccessful self‐control, suggests exciting new hypotheses alongside confounding questions for aggression and self‐regulation scholars. It also supports ongoing and broader paradigm shifts away from treating self‐control as a purely adaptive and desirable psychological capacity and toward approaching self‐control interventions with greater care, as they may amplify aggression instead of reducing it, with costly consequences.

Published: July 2023

AbstractRattus norvegicus and Rattus rattus are commensal pest rodents, considered reservoirs and vectors of zoonotic pathogens. In livestock farms, the wide use of antimicrobials and their release into the environment lead to high long‐term residual concentrations, which may in turn lead to the occurrence of antimicrobial resistance (AMR). Farm environments serve as AMR sources, resulting in the transmission of antimicrobial‐resistant bacteria and their AMR genes of livestock origin into wildlife. This study aimed to analyse the profile of enterobacteria carrying AMR determinants in rats captured in livestock farms to determine their potential vectors as for the spread of AMR. To this end, 56 rats (52 R. norvegicus and 4 R. rattus) were live‐trapped on 11 farms (pig, dairy, poultry and mixed farms) located in central Argentina, from spring 2016 to autumn 2017. From 50 of the R. norvegicus individuals and three of the R. rattus individuals found in 10 of the farms, we isolated 53 Escherichia coli and five Salmonella strains. Susceptibility to antimicrobials, genotypic profiles, minimal inhibitory concentration of colistin and the presence of mcr‐1 and genes encoding extended‐spectrum β‐lactamase (ESBL) were determined. Of the 58 isolates not susceptible to different antimicrobial classes, 28 of the E. coli strains and two of the Salmonella strains were defined as multi‐drug resistant (MDR). S. Westhampton and S. Newport recovered were not susceptible to ampicillin or all the cephems tested. One of the E. coli obtained showed resistance to colistin and harboured the mcr‐1 gene, demonstrated by PCR and conjugation. In two ESBL‐producing Salmonella isolated from rats, CTX‐M‐2 genes were responsible for the observed resistance to third‐generation cephalosporins. The MDR E. coli isolates showed several different resistance patterns (23), although some of them were the same in different individuals and different farms, with six resistance patterns, evidencing the dispersion of strains. These findings suggest that rats play a role in the dissemination of AMR determinants between animal, humans and environmental reservoirs.

Prolonged or intense exposure to heat can lead to a range of health effects. This study evaluated environmental heat exposure, heat-related symptoms, and acute physiological changes among 39 farmers in Kelantan, Malaysia. During the end of the monsoon season in February to Mac 2019, wet bulb globe temperature (WBGT) was collected in the farm environment to assess heat exposure. Blood pressure, heart rate, and body core temperature were measured pre-, mid and post-shift to measure the physiological response of farmers towards environmental heat. Sociodemographic, occupational information and heat-related symptoms that subjects had experienced were gathered using a questionnaire. The WBGT outdoor showed a high risk for heat stress and strain (> 28.0 oC) based on the American Conference of Governmental Industrial Hygiene (ACGIH) threshold limit values (TLVs). More than half (50%) of farmers reported heat-related symptoms including fatigue, lethargy, dizziness, rashes, and cramps. Significant physiological changes including heart rate, body temperature, and systolic blood pressure occurred across the work shift (p <0.05). However, no significant association (p>0.05) was found between the Acute Health Symptoms score (AHSS) with associated factors, thus no statistical model was further developed. In conclusion, farmers experienced significant psychological changes across the work shift. Preventive and control measures for heat stress are needed to reduce the risk of heat strain.
Concerns of Airborne Ammonia in Ice-Production Facilities: Enhancing protection of workers in Malaysia.
Authors: Yon Hazlina 
Published: July 2023

A study on profiling of ammonia concentration and its validation using two types of direct reading instruments has been conducted for eight months from September 2021 till May 2022 in four different zones in West Malaysia. The study is using a high performance multigas analyzer integrated with Fourier Transform Infrared (FTIR) and Multirae data analyzer to measure ammonia concentration in thirty-eight ice-production facilities in Malaysia. This study is limited to databases of ice-production facilities registered with the Department of Occupational Safety and Health (DOSH) Malaysia. The study involves thirty-eight ice-production facilities with fourteen compliance verification using USECHH checklist. The results of monitoring and validation confirmed that ammonia is detected at various locations in the factory layout. It is found to be localized and concentrated at the machine room followed by machine room combined with production room. Both instruments seem to show similar trend which can validate the profile obtained for ammonia in the ice facilities. Recommendations are suggested for employers to improve layout of the ice-production facilities based on these measurements.
The study also seeks to find a correlation between the compliance of these facilities with the Use and Standards of Exposure of Chemicals Hazardous to Health (USECHH) Regulations 2000 and compliance with ammonia checklist from the Guideline of Safe Management of Ammonia Refrigeration System 2020. Pre and post assessment is conducted using the same ammonia checklist to identify any gap. It was found that the results obtained for the USECHH compliance, ammonia checklist compliance either pre or post assessment are not positively correlated. This finding emphasizes that there is still a lack of commitment from these ice-production facilities even after the visits by authorities. Comparison between the monitoring data and the degree of compliance using ammonia checklist from the said guideline was also made. The results obtained emphasize that there is no strong correlation between the monitoring data and the degree of compliance using the ammonia checklist.
This study shows an insight of chemical management in Malaysia at ice-production facilities and provides suggestions, recommendations, measures and outcomes of enforcement. Future measures to be taken is also suggested to boost compliance. At the same time, the outcomes and implications of this study on chemical management and chemical safety status in Malaysia can also assist other developing countries to improve their chemical management. Future research with risk modelling of ammonia leakages could also be ventured into. Ice plants are recommended to redesign their layout based on this study.
Keywords: ammonia profiling, compliance enforcement, ice production facilities, lack of commitment, USECHH compliance.
On the boundedness and norm of certain generalized Hilbert operators in ℓp$\ell ^p$

Published: July 2023

AbstractThe Hilbert matrix has been extensively studied in the previous literature. In this paper, we look at generalized Hilbert operators arising from measures on the interval [0,1], such that the Hilbert matrix is obtained by the Lebesgue measure. We provide a necessary and sufficient condition for these operators to be bounded in and calculate their norm. Interestingly, we obtain complete results in this direction for both .

Published: July 2023

ImportanceAffordable surgical innovations (ASIs) provide simple, safe and equitable solutions in resource-limited settings. Effective dissemination is needed for widespread adoption and uptake of ASIs in low and middle-income countries (LMICs). However, surgical systems in these settings face challenges with adoption and uptake of ASIs, which remain unknown and/or unused even after supporting evidence is published. A surgery-specific, implementation science-informed framework can provide a roadmap delineating the actions needed to achieve this goal; however, none exist currently. This prompted the development of a well-defined roadmap for this purpose.MethodsThe roadmap was developed after several rounds of structured brainstorming discussions among the authors, who are LMIC-based experts in academic surgery, ASIs, global health and implementation science.Results and conclusionThe proposed ‘DISSEMINATE’ roadmap presents 18 non-sequential domains to be considered in a comprehensive approach to equitable accessibility for surgical innovations:Designof the innovation;Innovateby combining the IDEAL (Idea,Development,Exploration,Assessment andLong-term follow-up) surgical innovation framework with local multidisciplinary expertise;Substantiateavailable evidence;Scale upapplication of evidence in surgical practice;Shareknowledge on multidisciplinary platforms;Sustainability;Endorsementof the innovation by local catalysts;Mediapromotion;Identifyearly adopters;Improveand refine the innovation;Improviseduring setbacks;Implementationscience methods;Navigatethrough barriers;Aspirationalaffordability;Advocacyfor the value of ASIs;Toolsfor scalability and adoption;Evaluateimpact of dissemination; andExtenduse of the innovation to resource-rich settings. This surgery-specific roadmap provides structure for effective dissemination to help in overcoming know-do gaps in the use of ASIs in LMICs.

Published: July 2023

BackgroundBioprosthetic valves are often used for pulmonary valve replacement (PVR) and tricuspid valve replacement (TVR) because of concerns about mechanical valve thrombosis in the right heart. The purpose of this study was to assess prosthetic valve function and outcomes (prosthetic valve dysfunction, reoperations and major bleeding events) after mechanical PVR and TVR and to compare these to bioprostheses implanted in the same positions.MethodCase–control study of adults with congenital heart disease that underwent mechanical TVR or PVR (2003–2021) at Mayo Clinic Rochester, Minnesota. For each mechanical prosthesis, we identified two patients that received bioprosthesis in the same position (1:2 matching).ResultsWe identified 48 consecutive patients that underwent mechanical PVR (n=39, age 32 (26–38) years, men 22 (56%)) and/or mechanical TVR (n=17, age 36 (31–42) years, men 9 (53%)), as control group of 78 patients (age 30 (24–36) years, men 44 (56%)) and 34 patients (age 34 (29–39) years, men 18 (53%)) that underwent bioprosthetic PVR and TVR, respectively. The most common diagnoses in patients that received mechanical prosthesis were: tetralogy of Fallot (n=14, 19%), aortic stenosis status post Ross operation (n=11, 23%), truncus arteriosus (n=5, 11%), atrioventricular canal defect (n=4, 8%), Ebstein anomaly (n=3, 6%), double outlet right ventricle (n=2, 4%), valvular pulmonic stenosis (n=2, 4%). Compared with the bioprosthesis group, the mechanical prosthesis group had lower temporal increase in Doppler systolic mean gradient after PVR (∆ −1±2 vs 3±2 mm Hg, p<0.001) and Doppler diastolic mean gradient after TVR (∆ 0±1 vs 2±1 mm Hg, p=0.005). The mechanical prosthesis group also had lower risk of prosthetic valve dysfunction after PVR (1.0% vs 2.8% /year, p=0.02) and after TVR (2.6% vs 4.3% /year, p=0.008), but higher risk of major bleeding events (2.2% vs 0.1% /year, p<0.001).ConclusionsPatients that received right-sided mechanical valve prostheses had lower temporal increase in valve gradient, lower risk of prosthetic valve dysfunction, but higher risk of bleeding complications compared with those that underwent right-sided bioprosthetic valve implantation.
Challenging event horizons with spin (3/2) fields
Authors: Düztaş Koray 
Published: July 2023

AbstractWe attempt to destroy the event horizons of Kerr black holes by perturbing them with massless spin (3/2) fields. We carry out a detailed analysis by incorporating the explicit form of the absorption probabilities and backreaction effects due to the self energy of the test fields. For extremal and nearly extremal black holes, backreaction effects dominate for perturbations with large magnitudes. However, small perturbations can destroy the event horizons of extremal black holes and drive nearly extremal black holes closer to extremality. Eventually, nearly extremal black holes reach a certain stage where they can be continuously driven to extremality and beyond. Both the cosmic censorship conjecture and the third law of black hole dynamics can be violated by spin (3/2) fields. This directly follows from the fact that fermionic fields do not satisfy the null energy condition. Therefore this result does not contradict with the fact that cosmic censorship and the laws of black hole mechanics remain valid for perturbations satisfying the null energy condition.
Quantitative evidence for Arctic continental freezing in a high-CO

Abstract

We show that the Late Triassic–Early Jurassic continental Arctic experienced wintertime freezing conditions, despite the exceptionally high atmospheric CO

levels, by quantifying common lake ice-rafted debris (L-IRD) identified in the Junggar Basin of Xinjian, NW China. This L-IRD consists of outsized (0.1–12 mm) lithic clasts ‘floating’ in otherwise fine-grained, profundal lake sediment matrix. Laser-diffraction grain-size analysis demonstrates that the grain-size distribution for lacustrine strata of Junggar Basin is very similar to modern sediments from the seasonally ice-covered Sea of Okhotsk, reflecting a similar depositional mechanism. Three-dimensional computed tomography and two-dimensional thin sections demonstrate that the outsized clasts are dispersed, rather than confined to sand lenses or layers. These results are inconsistent with alternative methods of bimodal sediment deposition such as mud flows, algae rafting or root rafting. The discovery of Triassic–Jurassic continental freezing provides new context for understanding global climate during periods with high-CO

Serum amyloid A (SAA) is a cardiovascular risk factor and may serve as a predictor of infarct-related artery (IRA) patency in patients with ST-segment elevation myocardial infarction (STEMI). We measured SAA levels in STEMI patients who underwent percutaneous coronary intervention (PCI) and investigated their association with IRA patency. According to the Thrombolysis in Myocardial Infarction (TIMI) flow grade, 363 STEMI patients undergoing PCI in our hospital were divided into an occlusion group (TIMI 0-2) and a patency group (TIMI 3). The SAA level before PCI was significantly higher in STEMI patients with IRA occluded than in those with patent ones. At a cutoff value of 36.9 mg/L, SAA had a sensitivity of 63.0% and a specificity of 90.6% (area under the ROC curve [AUC] = .833, 95% CI: .793-.873, P < .001). Multivariate logistic regression analysis showed that SAA was an independent predictor of IRA patency in STEMI patients before PCI (odds ratio [OR] = 1.041, 95% CI: 1.020-1.062, P < .001). SAA can be used as a potential predictor of IRA patency in STEMI patients before PCI.
