description: We present a novel method for the global analysis of elastic electron-proton scattering when combining data sets from experiments with different overall normalization uncertainties. The method is a modification of one employed by the NNPDF collaboration in the fitting of parton distribution data. This method is an alternative to the 'penalty trick' method traditionally employed in global fits to proton electric and magnetic form factors, while avoiding the biases inherent in that approach. We discuss issues that arise when extending the method to nonlinear models. For data with $Q^2>1$ GeV$^2$ we find relatively minor differences to traditional model fits when the normalization uncertainties from different experiments are correctly accounted for. We discuss implications of this method for the well-known discrepancy between the form factor ratio $G_E/G_M$ extracted from the Rosenbluth and polarization transfer techniques.

description: Sonic detection and ranging (SODAR) is a technique for measuring wind speed and turbulence parameters from back-scattered sound waves. The SODAR projects a beam of sound straight up, as well as at angles slightly off vertical. Sound waves are scattered by variations in the density of the air and are then received back at the SODAR, the time of flight giving the height being probed. Doppler shifts provide information about the wind velocity. Since larger variations in the local density of the atmosphere imply higher turbulence, backscatter strength is related to turbulence. The instrument used here was a Scintec MFAS flat array SODAR. While the backscatter strength thus appears to be a direct indicator of the turbulence strength, calibration and an estimate of the variation of temperature with height is needed to process this strength into values for CT2 and Cn2. The calibration can be a baselining to a known CT2 value, or if the CT2 or Cn2 is unknown, a sensible heat value can be used (assuming free convection conditions). Typically, the sensible heat is calculated using the so-called Bulk Aerodynamic Method that assumes a certain surface roughness and a logarithmic wind profile, which generally only apply in free convection conditions. A more robust method, that perhaps applies when free convection conditions are not occurring, to obtain the sensible heat is via the Energy Balance or Bowen Ratio method. The energy balance of the atmosphere is composed of three main fluxes: ground heat flux, sensible heat flux, and latent heat flux. When summed, they result in the surface layer net radiation. The use of the Bowen ratio the ratio of sensible heat flux to latent heat flux allows a more direct assessment of the optical turbulence-driving surface layer sensible heat flux than do more traditional assessments of surface layer sensible heat flux. A comparison of the CT2 and Cn2 values from sensible heat using the Aerodynamic or energy balance methods will be evaluated against turbulence values obtained other means such as a sonic anemometer mounted on a small UAV.

description: Physics graduate studies are substantial efforts on the part of individual students, departments, and institutions of higher education. Understanding the factors that lead to student success and attrition is crucial for improving these programs. One factor that has recently started to be investigated is the broadly defined students' experiences related to support structures. The Aspects of Student Experience Scale (ASES), a Likert-style survey, was developed by researchers to do just that. In this study, we leverage the network approach for Likert-style surveys (NALS) methodology to provide a unique interpretation of responses to the ASES instrument for well-defined demographic groups. We confirm the validity of our findings by studying the stability of the NALS themes and investigating how they are expressed within demographic-based networks. We find that for all four themes in the original ASES study, certain thematic trends capturing students' experiences vary across the demographic-based networks in meaningful ways. We also reveal that for some demographic groups, there is an interesting interplay between, and mixing of, the original themes. Finally, our study showcases how NALS can be applied to other Likert-style datasets.

description: In the present work, we theoretically investigate gravitational lensing in the spacetime of a holonomy corrected Schwarzschild black hole. Analytical expressions for the light deflection angle are obtained in both the weak field limit and the strong field limit. Furthermore, we analyze observables, such as relativistic images and magnifications, and compare the results with those expected in a Schwarzschild spacetime. We discuss the possibilities and difficulties of investigating such a solution in practice.

description: Schools are an important setting because students spend much of their time in school and engage in physical activity during the school day that could exacerbate asthma symptoms. Our objective is to understand the barriers and facilitators to implementing an experimental community health worker-delivered care coordination program for students with asthma within the context of the West Philadelphia Controls Asthma study. Surveys (n = 256) and semi-structured interviews (n = 41) were completed with principals, teachers, nurses, and community health workers from 21 public and charter schools in West Philadelphia between January 2019 and September 2021. Survey participants completed the Evidence Based Practice Attitudes Scale, the Implementation Leadership Scale, and Organizational Climate Index. Semi-structured qualitative interview guides were developed, informed by the Consolidated Framework for Implementation Research. Participant responses indicate that they perceived benefits for schools and students related to the community health worker-based care coordination program. Several barriers and facilitators to implementing the program were noted, including challenges associated with incorporating the program into school nurse workflow, environmental triggers in the school environment, and challenges communicating with family members. An important facilitator that was identified was having supportive school administrators and staff who were engaged and saw the benefits of the program. This work can inform implementation planning for other locales interested in implementing community-based pediatric asthma control programs delivered by community health workers in schools.

description: Recent evidence indicates that Maternal Supplementation with Long-Chain n-3 Fatty Acids During Pregnancy Substantially Mitigates Offspring’s Asthma. Adding information regarding its cost-utility will undoubtedly allow its adoption, or not, in clinical practice guidelines. This research aimed to determine the cost-utility of LCPUFA supplementation in the third trimester of pregnancy to reduce the risk of wheezing and asthma in infants in Colombia. A Markov model was formulated to estimate the cost and quality-adjusted life-years (QALYs) attributed to individuals with severe asthma in Colombia, with a time horizon of five years and a cycle length of two weeks. Probabilistic sensitivity analysis and a value of information (VOI) analysis were conducted to evaluate the uncertainties in the case base. Cost-utility was assessed at a willingness-to-pay (WTP) value of US$5180. All costs were adjusted to 2021 with a 5% annual discounting rate for cost and QALYs. The mean incremental cost of LCPUFA supplementation versus no supplementation was US-43.65. The mean incremental benefit of LCPUFA supplementation versus no supplementation was 0.074 QALY. The incremental cost-utility ratio was estimated at US$590.68 per QALY. The outcomes derived from our primary analysis remained robust when subjected to variations in all underlying assumptions and parameter values. Supplementation strategy supplementation with long-chain n-3 fatty acids during pregnancy is cost-effective in reducing the risk of developing asthma during childhood in Colombia.

description: The interplay between chirality and magnetism has been a source of fascination among scientists for over a century. In recent years, chirality-induced spin selectivity (CISS) has attracted renewed interest. It has been observed that electron transport through layers of homochiral molecules leads to a significant spin polarization of several tens of percent. Despite the abundant experimental evidence gathered through mesoscopic transport measurements, the exact mechanism behind CISS remains elusive. In this study, we report spin-selective electron transport through single helical aromatic hydrocarbons that were sublimed in vacuo onto ferromagnetic cobalt surfaces and examined with spin-polarized scanning tunneling microscopy (SP-STM) at a temperature of 5 K. Direct comparison of two enantiomers under otherwise identical conditions revealed magnetochiral conductance asymmetries of up to 50% when either the molecular handedness was exchanged or the magnetization direction of the STM tip or Co substrate was reversed. Importantly, our results rule out electron-phonon coupling and ensemble effects as primary mechanisms responsible for CISS.

description: We argue that the higher weak isospin $SU(3)_L$ manifestly unifies dark matter and normal matter in its isomultiplets for which dark matter carries a conserved dark charge while normal matter does not. The resultant gauge symmetry is given by $SU(3)_C\otimes SU(3)_L \otimes U(1)_X\otimes U(1)_G$, where the first factor is the color group, while the rest defines a theory of scotoelectroweak in which $X$ and $G$ determine electric charge $Q=T_3-1/\sqrt{3}T_8+X$ and dark charge $D=-2/\sqrt{3}T_8+G$. This setup provides both appropriate scotogenic neutrino masses and dark matter stability as preserved by a residual dark parity $P_D=(-1)^D$. Interpretation of the dark charge is further discussed, given that $SU(3)_L$ is broken at very high energy scale.

description: We aimed to identify hub genes in chronic obstructive pulmonary disease (COPD) plasma through the exploration of a putative miRNA–mRNA regulatory network. Three datasets (GSE24709, GSE102915, GSE136390) were utilized to discern differentially expressed miRNAs (DEMs) between COPD and normal plasma. miRNET was employed to predict the potential targets of DEMs. Subsequent GO and KEGG analyses were conducted using DAVID. For the construction of the protein-protein interaction (PPI) network and screening of hub genes, STRING and Cytoscape were employed. The expression validation was assessed through GSE56768. The results revealed 395 genes targeted by up-regulated DEMs and 234 genes targeted by down-regulated DEMs. The target genes exhibited significant enrichment in the PI3K-Akt signaling pathway and the p53 signaling pathway. Through the validation of hub genes’ expression, we proposed two potential miRNA-mRNA interactions: miR-126-5p/miR-495-3p/miR-193b-3p - YWHAZ and miR-937-5p/miR-183-5p/miR-34c-5p/miR-98-5p/miR-525-3p/miR-215-5p - ACTB. In conclusion, our study posits potential miRNA-mRNA interactions in COPD by analyzing datasets from public databases, contributing valuable insights into the understanding of COPD pathogenesis and potential therapeutic avenues.

description: To describe clinical characteristics of young children presenting to the emergency department (ED) for early recurrent wheeze, and determine factors associated with subsequent persistent wheeze and risk for early childhood asthma. Retrospective cohort study of Medicaid-enrolled children 0–3 years old with an index ED visit for wheeze (e.g. bronchiolitis, reactive airway disease) from 2009 to 2013, and at least one prior documented episode of wheeze at an ED or primary care visit. The primary outcome was persistent wheeze between 4 and 6 years of age. Demographics and clinical characteristics were collected from the index ED visit. Logistic regression was used to estimate the association between potential risk factors and subsequent persistent wheeze. During the study period, 41,710 children presented to the ED for recurrent wheeze. Mean age was 1.3 years; 59% were male, 42% Black, and 6% Hispanic. At index ED visits, the most common diagnosis was acute bronchiolitis (40%); 77% of children received an oral corticosteroid prescription. Between 4 and 6 years of age, 11,708 (28%) children had persistent wheeze. A greater number of wheezing episodes was associated with an increased odds of ED treatment with asthma medications. Subsequent persistent wheeze was associated with male sex, Black race, atopy, prescription for bronchodilators or corticosteroids, and greater number of visits for wheeze. Young children with persistent wheeze are at risk for childhood asthma. Thus, identification of risk factors associated with persistent wheeze in young children with recurrent wheeze might aid in early detection of asthma and initiation of preventative therapies.

description: We determine $J^{PC}=0^{++}$ and $2^{++}$ hadron-hadron scattering amplitudes in the charmonium energy region up to 4100 MeV using lattice QCD, a first-principles approach to QCD. Working at $m_π\approx 391$ MeV, more than 200 finite-volume energy levels are computed and these are used in extensions of the Lüscher formalism to determine infinite-volume coupled-channel scattering amplitudes. We find that this energy region contains a single $χ_{c0}$ and a single $χ_{c2}$ resonance. Both are found as pole singularities on the closest unphysical Riemann sheet, just below 4000 MeV with widths around 70 MeV. The largest couplings are to kinematically-closed $D^* \bar{D}^*$ channels in $S$-wave, and couplings to several decay channels consisting of pairs of open-charm mesons are found to be large and significant in both cases. Above the ground state $χ_{c0}$, no other scalar bound-states or near-$D\bar{D}$ threshold resonances are found, in contrast to several theoretical and experimental studies.

description: This study aimed to analyze the sensitization rate of different aeroallergens in children of different age, sex, and disease groups, describe the changing trend of different aeroallergens in different ages, and analyze the sensitization risk factors for asthma. Children (<18 years old) with suspected atopic diseases who visited the Department of Allergy of Children’s Hospital Affiliated to Capital Institute of Pediatrics and underwent a skin prick test (SPT) were retrospectively enrolled from January 2019 to November 2021. A total of 5465 patients (3514 boys, 1951 girls; mean age, 7 ± 3 years) were enrolled. Of them, 3703 patients (67.8%) were sensitized to at least one aeroallergen. Before 4 years of age, mold was the most prevalent aeroallergen (103/380 [27.1%]), whereas after 4 years of age, weed pollen was the most prevalent aeroallergen. After 6 years of age, tree pollen became the second most prevalent aeroallergen. After 12 years of age, the sensitization rate of indoor aeroallergens was lower than that of outdoor aeroallergens. Logistic regression showed that sensitization to mold (odds ratio [OR]:1.4, 95% confidence interval (CI): 1.2–1.7, p < 0.001), animal dander (OR: 1.6, 95% CI: 1.4–1.9, p < 0.001), and polysensitization (OR: 1.4, 95% CI: 1.0–1.8, p = 0.038) were potential sensitization risk factors for asthma. Mold is an important allergen in early life. Different kinds of allergens affect different age groups. Patients who are sensitized to mold or animal dander or experience polysensitization should be carefully monitored for asthma risk.

description: In order to explore the spectrum of hidden-charm scalar and tensor resonances, we study meson-meson scattering with $J^{PC}=0^{++}, 2^{++}$ in the charmonium energy region using lattice QCD. Employing a light-quark mass corresponding to $m_π\approx 391$ MeV, we determine coupled-channel scattering amplitudes up to around 4100 MeV considering all kinematically relevant channels consisting of a pair of open-charm mesons or a charmonium meson with a light meson. A single isolated scalar resonance near 4000 MeV is found with large couplings to $D\bar{D}$, $D_s \bar{D}_s$ and the kinematically closed $D^* \bar{D}^*$ channel. A single tensor resonance at a similar mass couples strongly to $D\bar{D}$, $D\bar{D}^*$ and $D^* \bar{D}^*$. We compare the extracted resonances to contemporary experimental candidate states, previous lattice results and theoretical modeling. In contrast to several other studies, we do not find any significant feature in the scalar amplitudes between the ground state $χ_{c0}(1P)$ and the resonance found around 4000 MeV.

description: To evaluate the economic value of mepolizumab as an add-on therapy to the standard of care (SoC) for patients with severe eosinophilic asthma in China. A Markov model with three health conditions was constructed to calculate the incremental cost per quality-adjusted life year (QALY) in mepolizumab with SoC and SoC only groups from the perspective of the Chinese healthcare system throughout an entire lifespan. The model was populated with local costs, while efficacy parameters were obtained from the global Phase III MENSA trial and mortality was derived from two surveys. One-way and probabilistic sensitivity analyses were conducted. Additional scenario analysis was used to estimate the cost-effectiveness impact of changes in the price of mepolizumab. Over the lifetime treatment horizon, the incremental cost-effectiveness ratio (ICER) of mepolizumab plus SoC compared to SoC alone was $170 648.73 per QALY. Sensitivity analyses focused on these results. Scenario analysis showed that mepolizumab would require a price reduction of at least 82% to reach the current willingness-to-pay (WTP=$38 223.34/QALY) threshold. Mepolizumab is not a cost-effective healthcare resource in China at its current pricing.

description: The International Congress on Analytical Nanoscience and Nanotechnology (NyNA) is a renowned annual event that gathers leading experts, researchers, and professionals in the fields of nanoscience and nanotechnology. The congress serves as a global platform for discussing the latest innovations, research, and applications in analytical nanoscience, with a focus on cutting-edge technologies that address real-world challenges. The main goal of this conference is to promote the development and the new knowledge on Analytical Chemistry concepts applied to Nanoscience and Nanotechnology under the following topics:

• Nano(bio)sensors

• Nanomaterials for sample preparation

• Analytical Nanometrology

• Detection, characterization, and quantification of nanomaterials

• Applied analytical strategies involving nanomaterials

• Other nanotechnological applications and miniaturized nanosystems.

The event was a huge success with around 180 attendees and I had the great honor of delivering a plenary lecture entitled "Paper-based (bio)sensors nanomodified for sustainable and smart analyses" at this prestigious conference. The lecture provided an opportunity to share cutting-edge research in the field of nanotechnology and its application to biosensing, with an emphasis on sustainability and smart analytical systems

 

I highlighted the distinct advantages of using paper in biosensor development, as outlined in my review, "Electrochemical paper-based devices: When the simple replacement of the support to print ecodesigned electrodes radically improves the features of the electrochemical devices" published in  Current Opinion in Electrochemistry SI: Emerging Opinions (2022) [F. Arduini. Curr. Opin. Electrochem. 2022, 101090]: “Paper-based electrochemical (bio)sensors have emerged as highly attractive analytical devices for their superior sustainable features, such as avoiding the use of polyester as support and the reduction of waste, being incinerated after use. However, paper-based electrochemical (bio)sensors have recently demonstrated further advantages, including the simple combination with vertical microfluidics and their use as a reservoir to deliver smart electrochemical (bio)sensors able to i) contain the reagents, ii) preconcentrate the target analyte, and iii) synthesize the nanomaterials inside the paper network. Furthermore, these devices have demonstrated their ability to overcome the limitations of the other printed electrochemical sensors in the measurement of entirely liquid samples by detecting the target analyte in the aerosol phase or solid sample, without the additional sampling system. These achievements highlight their valuable and varied advantages in the sensing sector”. Our new technology within the Phoenix-OoC (Organ-on-a-Chip) project builds on these benefits: the Phoenix-OoC system is designed to be simple, highly scalable and its architecture supports the analysis of a wide range of analytes, taking advantage of the advantages of paper.

description: Blockchain is no longer a hype technology. Powerful applications exist in many contexts, but in others, progress is slow. To investigate reasons for the differences in uptake, this thesis explores two antithetical contexts: public administration and electric power systems. While blockchain applications in public administration are gaining traction, many blockchain projects in electric power systems have been abandoned. This thesis argues that applications of blockchain are successful where the anticipated benefits are specific and where organizational, technical, and regulatory challenges appear manageable. Moreover, blockchain is successful where decentralized organizational structures dominate. The thesis includes seven papers that investigate various aspects of technology-driven decentralization and blockchain adoption in the two above-mentioned contexts. Their abstracts are available in the appendix and their full texts in the supplemental material. The first two papers examine compliance with the requirements of the EU’s General Data Protection Regulation, a particularly pertinent challenge for blockchain projects. The third paper reflects on the importance of experimentation when working with innovative and unfamiliar technologies. The fourth paper investigates a successful implementation of blockchain in public administration; namely, a federal infrastructure to coordinate German asylum procedures. Papers five, six, and seven focus on technology-driven decentralization in electric power systems. They explore essential foundations for understanding the lack of successful blockchain projects in the areas of peer- to-peer trading and microgrid operation. The fifth paper suggests that these application areas have unclear overall profitability, even when the use of energy storage helps to draw on several revenue streams. The sixth and seventh paper further challenge the need for residential peer-to- peer trading and decentralized microgrid operation by establishing the financial and stability benefits of local grid managers and identifying electricity tariffs that can encourage desirable and sustainable operation by such managers.

description: Physical activity programs focusing on fall prevention often overlook upper-limb strength, which is important for transferring, balance recovery, and arresting a fall. We developed and evaluated a physical activity program, Mobility-Fit for older adults in Assisted Living (AL) that includes upper-limb strengthening, agility, coordination, and balance exercises. Thirty participants (85 ± 6 years) were recruited from two AL facilities; 15 were assigned to Mobility-Fit (three times/week, 45 min/session for 12 weeks) and 15 maintained usual care. Twenty-two participants (11 in each group) completed the study. We compared outcome changes between groups and interviewed participants and staff to explore the effectiveness and feasibility of the program. Among participants who attended Mobility-Fit, knee extension strength increased by 6%, reaction time decreased by 16%, and five-time sit-to-stand duration decreased by 15%. Conversely, participants in the usual care group had a 6% decrease in handgrip strength. Changes of these outcomes were significantly different between two groups (p < 0.05). Participants enjoyed the program and staff suggested some changes to improve attendance. Our results indicate that Mobility-Fit is feasible to deliver and beneficial for older adults in AL and may guide future clinical trials to evaluate the effectiveness of upper limb strengthening on safe mobility of older adults in care facilities.

description: In theoretical models of galaxy evolution, black hole feedback is a necessary ingredient in order to explain the observed exponential decline in number density of massive galaxies. Most contemporary black hole feedback models in cosmological simulations rely on a constant radiative efficiency (usually $η\sim 0.1$) at all black hole accretion rates. We present the Obsidian sub-grid model, a synthesis model for the spin-dependent radiative efficiencies of three physical accretion rate regimes, i.e. $η= η(j, \dot{M}_\mathrm{acc})$, for use in large-volume cosmological simulations. The three regimes include: an advection dominated accretion flow ($\dot{M}_\mathrm{acc} < 0.03\,\dot{M}_\mathrm{Edd}$), a quasar-like mode ($0.03 < \dot{M}_\mathrm{acc} / \dot{M}_\mathrm{Edd} < 0.3$), and a slim disc mode ($\dot{M}_\mathrm{acc} > 0.3\,\dot{M}_\mathrm{Edd}$). Additionally, we include a large-scale powerful jet at low accretion rates. The black hole feedback model we present is a kinetic model that prescribes mass loadings but could be used in thermal models directly using the radiative efficiency. We implement the Obsidian model into the Simba galaxy evolution model to determine if it is possible to reproduce galaxy populations successfully, and provide a first calibration for further study. Using a $2\times1024^3$ particle cosmological simulation in a $(150\,\mathrm{cMpc})^3$ volume, we found that the model is successful in reproducing the galaxy stellar mass function, black hole mass-stellar mass relationship, and stellar mass-halo mass relationship. Moving forward, this model opens new avenues for exploration of the impact of black hole feedback on galactic environments.

description: Dynamical descriptions and modeling of natural systems have generally focused on fixed points, with saddles and saddle-based phase-space objects such as heteroclinic channels/cycles being central concepts behind the emergence of quasi-stable long transients. Reliable and robust transient dynamics observed for real, inherently noisy systems is, however, not met by saddle-based dynamics, as demonstrated here. Generalizing the notion of ghost states, we provide a complementary framework that does not rely on the precise knowledge or existence of (un)stable fixed points, but rather on slow directed flows organized by ghost sets in ghost channels and ghost cycles. Moreover, we show that appearance of these novel objects is an emergent property of a broad class of models, typically used for description of natural systems.

description: Social connectedness and engagement are particularly important among groups who are at risk of experiencing social isolation, such as immigrant older adults. The objective of our study was to understand the social relationships of aging Muslim Lebanese immigrants living in Canada by exploring their lives in their ethnic and wider communities. This study used a life course perspective and adopted a constructivist narrative inquiry to understand the diverse lived experiences of four older adults who immigrated to Canada during early adulthood. Participants engaged in a narrative interview and follow-up session in which they storied their lived experiences. Findings describe one core theme, cultivating social relationships through family, friends, and community interdependence, and three related sub-themes: (1) navigating and creating family interdependence and planting new roots; (2) family interdependence in later life: the important role of grandchildren; and (3) cultivating ethnic and local interdependence to support aging in place. The participants’ stories provided an understanding of how culture, religion, aging, family, and immigration experiences interrelated throughout their life course and shaped their social relationships during later life. This study sheds new insight on the importance of culturally tailored activities and awareness about the social needs of immigrant older adults.
