description: The C5a peptidase from Streptococcus pyogenes (ScpA) is a highly specific enzyme with potential therapeutic value. ScpA is a good model for studying determinants of specificity in the multidomain immunomodulatory enzymes (IMEs), which comprise a large family of bacterial surface proteases. The surface exposed region of ScpA has 5 main domains which includes 3 C-terminal Fn3-like domains (Fn1, Fn2 and Fn3) (Kagawa et al. 2009). Progressive deletion of the Fn3-like domains from the C-ter resulted in loss of enzyme activity and showed an important role for the Fn2 domain in enzyme function. Functional investigation of specific acidic residues on the Fn2 domain identified 3 residues 30–50 Å from the catalytic site (D783, E864 and D889) which impacted to differing degrees on binding and on catalysis, supporting the presence of an exosite on the Fn2. In particular, residue D783 was observed to impact on both substrate binding affinity and the activity of ScpA. A double mutant cycle analysis showed energetic coupling between the targeted ScpA residues and residues in the core portion (residues 1–67) of the C5a substrate. The data supports the presence of a communication network between the active site and the exosite on Fn2. These findings provide a basis for rational engineering of this important enzyme family to enhance stability, activity and/or specificity.

Open Access publishing

description: Though Diamond Open Access is widely considered the most progressive publishing form for Open Access journals, Diamond Open Access journals face various challenges including (technological) standardisation, securing sustainability for journals and juggling a broad set of workflows while depending largely on voluntary work.

 The project CRAFT-OA (Creating a Robust Accessible Federated Technology for Open Access) aims to help standardize Diamond Open Access journals by offering technological innovations available to all Diamond Open Access journals alike. Furthermore, in cooperation with the DIAMAS project, CRAFT-OA will foster a community of practice, further enhancing Diamond Open Access publishing by uniting the scholarly community behind common goals.

 The proposed poster will include an overview of the key objectives of the project as well as a section dedicated to explaining which steps the project teams aim to take in order to make these goals become reality. Additionally, the poster will include a visualization of how the collaboration among the project group DIAMAS, CRAFT-OA and PALOMERA is set up. It will also show how these collaborations work on a structural level. Specifically, it will be explained how the results of DIAMAS and CRAFT-OA complement each other and will be crucial to set up a Capacity Centre supporting institutional Diamond Open Access publishers by providing all information, best practice guidelines, workflows and training materials relating to Diamond Open Access in one place.

description: We investigate theoretically the polarization properties of the quantum dot's optical emission from chiral photonic crystal structures made of achiral materials in the absence of external magnetic field at room temperature. The mirror symmetry of the local electromagnetic field is broken in this system due to the decreased symmetry of the chiral modulated layer. As a result, the radiation of randomly polarized quantum dots normal to the structure becomes partially circularly polarized. The sign and degree of circular polarization are determined by the geometry of the chiral modulated structure and depend on the radiation frequency. A degree of circular polarization up to 99% can be achieved for randomly distributed quantum dots, and can be close to 100% for some single quantum dots.

Determinants of Complete COVID-19 Vaccination Status Among Immigrant Population in North Carolina USA, Qualtrics Survey July-August 2022
Creators: name: Mexan Mapouka

description: The COVID-19 pandemic has disproportionately affected certain minority populations and exposed barriers to vaccination. We explored factors associated with complete and incomplete COVID-19 vaccination status among immigrant population in North Carolina, USA.
The factors associated with COVID-19 vaccination status were explored using a cross-sectional study of 98 eligible participants who took an online survey between April and July 2022, on the completeness of COVID-19 vaccine and associated factors. Eligible participants included either U.S. citizens, green card holders, or adults with one of the following immigration statuses: refugee, asylee, asylum pending case, an undocumented immigrant, and other groups. Analysis of frequencies, bivariate and multivariate logistic regression was performed using SAS Institute, Cary, North Carolina v. 9.4 to report the descriptive statistics and prevalence odds ratios (POR) between certain groups with 95%.
The unadjusted POR of complete COVID-19 vaccination status comparing women to men was 0.42, 95% CI 0.20,0.89.  Participants between 25 and 34 years old were less likely to have complete vaccination status compared to those between 35 and 44 years old; unadjusted POR: 0.21, 95% CI 0.08, 0.55.  Immigrants were less likely to have complete vaccine status compared to Non-immigrant POR 0.47, 95% CI 0.24,0.92. Further factors associated with incomplete COVID-19 vaccination status were vaccine safety concerns, mistrust, transportation issues, language barriers, the proximity of the vaccination point, inconvenient work schedules, the absence of healthcare insurance, and many others.
Policy and public health programs should address barriers to access healthcare faced by the immigrant population.

description: We extend the quantum jump method to nearly adiabatically driven open quantum systems in a way that allows for an accurate account of the external driving in the system-environment interaction. Using this framework, we construct the corresponding trajectory-dependent work performed on the system and derive the integral fluctuation theorem and the Jarzynski equality for nearly adiabatic driving. We show that such identities hold as long as the stochastic dynamics and work variable are consistently defined. We numerically study the emerging work statistics for a two-level quantum system and find that the conventional diabatic approximation is unable to capture some prominent features arising from driving such as the continuity of the probability density of work. Our results reveal the necessity of using accurate expressions for the drive-dressed heat exchange in future experiments probing jump time distributions.

description: Social protection programs are not introduced in a vacuum and it is important to understand what effects such programs have on existing informal support networks of family, friends and community members. A social cash transfer may reduce receipt of informal financial support, which can water down part of the program's impact. However, cash transfers can also reduce barriers to social participation and enable participants to engage in reciprocal support systems. We use data from the quasi-experimental mixed method impact evaluation of Ghana's Livelihood Empowerment Against Poverty (LEAP) 1000 program, a social cash transfer program for pregnant women and mothers of children under one year living in poverty, to estimate program effects on social support and participation. Using a difference-in-differences approach we find that LEAP 1000 increases overall social support, as well as both emotional and instrumental support. In addition, program beneficiaries are more likely to participate in community groups. In in-depth interviews, participants confirmed increased support with descriptions of improved access to financial markets, such as borrowing money or contributing to local savings schemes, and strengthening of social participation in local groups and gatherings. Beneficiary women also highlighted reduced need for economic support and new opportunities to support others. By creating opportunities for additional social support within the household and community, LEAP 1000 crowded-in support, rather than reducing existing sources of support or crowding-out support.

description: ATP is related to the occurrence of many diseases, its facile, sensitive and accurate determination in real samples is needed for disease screening and treatment. Although some methods realized the sensitive detection of ATP using the signal amplification of cyclic reactions or nanoparticles, complex experimental processes limit their applications. In this paper, we report a simple surface plasmon resonance (SPR) method based on a single stranded DNA probe. The probe has dual recognition sites of ATP and Ag+; namely the ATP aptamer located in the middle of the probe and five cytosine (C) at both ends of the probe. In the absence of ATP, the probe transforms into a rigid hairpin structure by forming C-Ag+-C structures and produces a large SPR signal. However, once the probe interacts with ATP, three-dimensional structures are formed, and then the Ag+-induced probe configuration change is smaller, resulting in an small SPR signal. The signal difference before and after the probe interacts with ATP is proportional to the analyte concentration. The probe configuration change is in the optimum area for SPR detection, ensuring the sensitive ATP determination. The signal difference has a linear response with the logarithm of ATP concentration from 0.05 to 500 nM with a detection limit of 15 pM. Moreover, the strategy was demonstrated to determine ATP in serum samples with satisfactory recoveries. The results show that this simple and sensitive method has potential applications for clinical ATP determination.

We give a formula for its Hilbert--Poincaré series in a fermionic (cancellation-free) form which turns out to coincide with the generating function of the plane partitions over the $(1,1)$-hook. Our arguments are based on a super version of the Beilinson--Drinfeld--Raïs--Tauvel theorem which we prove by producing an explicit basis of invariants of the symmetric algebra of polynomial currents associated with $\mathfrak{gl}(1|1)$. We identify the invariants with affine supersymmetric polynomials via a version of the Chevalley theorem.

description: We conducted high dispersion spectroscopic observations of 50 superflare stars with Subaru/HDS, and measured the stellar parameters of them. These 50 targets were selected from the solar-type (G-type main sequence) superflare stars that we had discovered from the Kepler photometric data. As a result of these spectroscopic observations, we found that more than half (34 stars) of our 50 targets have no evidence of binary system. We then estimated effective temperature ($T_{\rm{eff}}$), surface gravity ($\log g$), metallicity ([Fe/H]), and projected rotational velocity ($v\sin i$) of these 34 superflare stars on the basis of our spectroscopic data. The accuracy of our estimations is higher than that of Kepler Input Catalog (KIC) values, and the differences between our values and KIC values ($(ΔT_{\rm{eff}})_{\rm{rms}} \sim 219$K, $(Δ\log g)_{\rm{rms}} \sim 0.37$ dex, and $(Δ\rm{[Fe/H]})_{\rm{rms}} \sim 0.46$ dex) are comparable to the large uncertainties and systematic differences of KIC values reported by the previous researches. We confirmed that the estimated $T_{\rm{eff}}$ and $\log g$ values of the 34 superflare stars are roughly in the range of solar-type stars. In particular, these parameters and the brightness variation period ($P_{0}$) of 9 stars are in the range of "Sun-like" stars ($5600\leq T_{\rm{eff}}\leq 6000$K, $\log g\geq$4.0, and $P_{0}>$10 days). Five of the 34 target stars are fast rotators ($v \sin i \geq 10$km s$^{-1}$), while 22 stars have relatively low $v \sin i$ values ($v \sin i<5$km s$^{-1}$). These results suggest that stars whose spectroscopic properties similar to the Sun can have superflares, and this supports the hypothesis that the Sun might cause a superflare.

Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at sqrt(s) = 8 TeV

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons originating from a displaced secondary vertex. Events corresponding to an integrated luminosity of 19.6 (20.5) inverse femtobarns in the electron (muon) channel were collected with the CMS detector at the CERN LHC in proton-proton collisions at sqrt(s) = 8 TeV. No significant excess is observed above standard model expectations. Upper limits on the product of the cross section and branching fraction of such a signal are presented as a function of the long-lived particle's mean proper decay length. The limits are presented in an approximately model-independent way, allowing them to be applied to a wide class of models yielding the above topology. Over much of the investigated parameter space, the limits obtained are the most stringent to date. In the specific case of a model in which a Higgs boson in the mass range 125-1000 GeV decays into a pair of long-lived neutral bosons in the mass range 20-350 GeV, each of which can then decay to dileptons, the upper limits obtained are typically in the range 0.2-10 fb for mean proper decay lengths of the long-lived particles in the range 0.01-100 cm. In the case of the lowest Higgs mass considered (125 GeV), the limits are in the range 2-50 fb. These limits are sensitive to Higgs boson branching fractions as low as 1E-4.

description: A joint transmitter-receiver energy harvesting model is considered, where both the transmitter and receiver are powered by (renewable) energy harvesting source. Given a fixed number of bits, the problem is to find the optimal transmission power profile at the transmitter and ON-OFF profile at the receiver to minimize the transmission time. With infinite capacity at both the transmitter and receiver, optimal offline and optimal online policies are derived. The optimal online policy is shown to be two-competitive in the arbitrary input case. With finite battery capacities at both ends, only random energy arrival sequence with given distribution are considered, for which an online policy with bounded expected competitive ratio is proposed.

A detailed analysis of the symmetry properties of both the classical and supersymmetric versions of the Gauss-Weingarten equations is performed. A supersymmetric generalization of the conjecture establishing the necessary conditions for a system to be integrable in the sense of soliton theory is formulated and illustrated by the examples of supersymmetric versions of the sine-Gordon equation and the Gauss-Codazzi equations.

description: This study used data from 340 mother–child dyads to examine characteristics of children with co-occurring diagnoses of anxiety and externalizing disorders and compared them with children with a sole diagnosis or no diagnosis. Comparisons were made using 4 child-diagnostic groups: anxiety-only, externalizing-only, co-occurrence, and no-problem groups. Most mothers were characterized by low income and histories of psychiatric diagnoses during the child’s lifetime. Analyses using multinomial logistic regressions found the incidence of co-occurring childhood disorders to be significantly linked with maternal affective/anxiety disorders during the child’s lifetime. In exploring implications for developmental competence, we found the co-occurrence group to have the lowest level of adaptive functioning among the 4 groups, faring significantly worse than the no-problem group on both academic achievement and intelligence as assessed by standardized tests. Findings underscore the importance of considering co-occurring behavior problems as a distinct phenomenon when examining children’s developmental outcomes.

description: Witnessed violence has significant negative consequences for youth behavior and mental health. However, many findings on the impact of witnessed violence have been based on a single informant. There is a general lack of consistency between caregiver and youth reports on both witnessed violence and behavioral problems. This study included data from both caregivers and youth and incorporated a multi-source analytic approach to simultaneously examine the association between youth witnessed violence and externalizing and internalizing behavior problems. Data from 875 caregivers and 812 youth were collected as part of the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Findings showed that youth reported more witnessed violence than did their caregivers, and caregivers reported more externalizing and internalizing behavior problems than did youth. Further, the source of information had a significant impact on the association between witnessed violence and internalizing behaviors. These findings highlight the need to incorporate multiple sources and multi-informant analytic techniques to eliminate methodological limitations to understanding the effect of witnessed violence on youth behavioral problems.

description: Stability and change in maternal intrusiveness during early childhood is rarely explored, particularly within African American families. The current study examined the prediction of maternal intrusiveness during the first 3 years of life among mothers of rural, low-income African American boys and its relation to school-related outcomes. Observations of mothers (N=230) interacting with children at 6, 24, and 36 months were coded and analyzed. Predictors of the trajectories and child outcomes were assessed using questionnaires and various tasks. On average, mothers of African American boys increased in intrusiveness across the first 3 years of life. Cumulative sociodemographic risk was associated with initial levels of intrusiveness, and child fearfulness and maternal negative regard predicted increases in intrusiveness overtime. After controlling for sociodemographic risk, child temperament, and parental negativity, increases in intrusiveness over the first 3 years of life were associated with lower levels of expressive communication, inhibitory control, and intellectual functioning but not with attention focusing. Comprehensive parenting intervention efforts aimed toward improving children’s outcomes must take into consideration the broader socioeconomic and affective context in which parenting behaviors occur, as well as stability and change in parenting over time.

description: We establish an exact formula relating the survival probability for certain Lévy flights (viz. asymmetric $α$-stable processes where $α= 1/2$) with the survival probability for the order statistics of the running maxima of two independent Brownian particles. This formula allows us to show that the persistence exponent $δ$ in the latter, non Markovian case is simply related to the persistence exponent $θ$ in the former, Markovian case via: $δ=θ/2$. Thus, our formula reveals a link between two recently explored families of anomalous exponents: one exhibiting continuous deviations from Sparre-Andersen universality in a Markovian context, and one describing the slow kinetics of the non Markovian process corresponding to the difference between two independent Brownian maxima.

description: Recent advances in molecular genetics impact the health care and outcome of patients with acute lymphoblastic leukemia (ALL). BCR-ABL, a common molecular defect in adult ALL, is a valuable tumor marker whose detection influences prognosis and clinical management decisions. Molecular methods such as fluorescence in situ hybridization (FISH), reverse-transcriptase polymerase chain reaction (rtPCR), and real-time quantitative rtPCR can be used to detect the chimeric BCR-ABL gene or its transcripts. These molecular assays improve our ability to measure residual disease and to estimate risk of relapse. On the horizon are gene expression profiles that will likely provide additional information beyond what is obtainable with current clinical and laboratory approaches.

description: Recently there has been much interest in the tauonic semileptonic meson decays B -> D + tau + nu_tau and B -> D* + tau + nu_tau where one has found larger rates than what is predicted by the Standard Model. We analyze the corresponding semileptonic baryon decays Lambda_b(0) -> Lambda_c(+) + tau(-) + antinu_tau with particular emphasis on the lepton helicity flip and scalar contributions which vanish for zero lepton masses. We calculate the total rate, differential decay distributions, the longitudinal and transverse polarization of the daughter baryon Lambda_c(+) and the tau-lepton, and the lepton-side forward-backward asymmetries. The nonvanishing polarization of the daughter baryon Lambda_c(+) leads to hadron-side asymmetries in e.g. the decay Lambda_c(+) -> Lambda(0) + pi(+) and azimuthal correlations between the two final state decay planes which we specify. We provide numerical results on these observables using results of the covariant confined quark model. We find large lepton mass effects in the q2-spectra and in the polarization observables.

description: Laser-plasma technology promises a drastic reduction of the size of high energy electron accelerators. It could make free electron lasers available to a broad scientific community, and push further the limits of electron accelerators for high energy physics. Furthermore the unique femtosecond nature of the source makes it a promising tool for the study of ultra-fast phenomena. However, applications are hindered by the lack of suitable lens to transport this kind of high-current electron beams, mainly due to their divergence. Here we show that this issue can be solved by using a laser-plasma lens, in which the field gradients are five order of magnitude larger than in conventional optics. We demonstrate a reduction of the divergence by nearly a factor of three, which should allow for an efficient coupling of the beam with a conventional beam transport line.

description: Clay adsorption is a critical process responsible for the mobilization and cycling of potassium (K) on Earth's surface. Recent studies emphasized the potential of using stable K isotopes (δ41K) to understand chemical weathering. However, the direction, degree, and mechanism of K isotopic fractionation linked to clay K uptake during chemical weathering remain poorly constrained. This work investigated the mechanism of K adsorption on clays (kaolinite and smectite) and the isotopic fractionation in three experimental sets with K-containing solutions. The time-series experiments revealed that the adsorption and isotope equilibria were attained after less than 12-hour reaction. Potassium adsorption rate slowed down and its isotopic fractionation approached the steady-state during 15-day reaction. The pH-dependent experiments demonstrated that the percentage of clay K adsorption and the isotopic composition of adsorbed K (and aqueous K) display negative linear correlations. Net isotopic fractionation between adsorbed and aqueous phases (Δ41Kad-aq) remained near-constant (0.6–0.8‰), regardless of variations in pH ranging from 4 to 10. The concentration-control experiments demonstrated that the percentage of K adsorption decreased with increasing KCl concentrations from 0.005 to 20 mM. The δ41K values of aqueous K reached the minimum of −0.53‰ after 92.7% K adsorbed (initial KCl of 0.005 mM). Potassium adsorption was substantially suppressed as ionic strength (fixed by Na+) increased from 0.001 to 0.5 M without apparent Δ41Kad-aq variations. The K K-edge XANES demonstrated that primary K incorporated in clay lattice and surface KCl derived from sorbed K+ and Cl− synchro-dehydration can be identified after drying of clays. These features indicate that adsorbed K+ was bounded onto clays as outer-sphere complexes, which can be replaced with excess Na+ at high ionic strength. Based on experimental results, we cannot distinguish specific mineralogy regulation on K isotopic fractionation. In sum, isotopically heavy K is preferentially sorbed on clay minerals. The results confirm an equilibrium fractionation path independent of reaction time, pH, ionic strength, and initial KCl concentration. Observed K isotopic fractionation is best fitted by an equilibrium isotopic fractionation law with a fractionation factor αad-aq of 1.00075. We highlight the opposite direction of K isotopic fractionation in clay adsorption and structural incorporation during chemical weathering, and their comparative contributions should be considered for future field investigations.

description: Epstein-Barr Virus (EBV) infects nearly all humans and then persists for the life of the host. In some people who later develop cancer, EBV DNA is present within malignant cells and circulates at elevated levels in the plasma. In the current study, we validated five novel quantitative polymerase chain reaction (Q-PCR) assays targeting disparate but highly conserved segments of the EBV genome (BamH1W, EBNA1, LMP1, LMP2, and BZLF1). Each assay was sensitive to as few as 50 copies of EBV DNA per reaction and was linear across at least four orders of magnitude. When applied to paraffin-embedded tissues in concert with EBV-encoded RNA (EBER) in situ hybridization, the BamH1W and EBNA1 assays were the most informative, while use of the entire battery of EBV PCR assays may help identify genomic polymorphisms or deletions. Higher viral loads were found in the 17 EBER-positive compared with the 13 EBER-negative tumors (means 84,978 versus 22 copies of EBV per 100,000 cells, respectively). The five Q-PCR assays were also informative in plasma samples where EBV was measurable in all nine patients with lymphoma or infectious mononucleosis, whereas EBV was undetectable in all nine healthy controls. The findings suggest that Q-PCR is an effective method of distinguishing disease-associated virus from incidental virus in paraffin-embedded tissue and in plasma samples.
Low temperature Glauber dynamics under weak competing interactions

description: We consider the low but nonzero temperature regimes of the Glauber dynamics in a chain of Ising spins with first and second neighbor interactions $J_1,\, J_2$. For $0 < -J_2 / | J_1 | < 1$ it is known that at $T = 0$ the dynamics is both metastable and non-coarsening, while being always ergodic and coarsening in the limit of $T \to 0^+$. Based on finite-size scaling analyses of relaxation times, here we argue that in that latter situation the asymptotic kinetics of small or weakly frustrated $-J_2/ | J_1 |$ ratios is characterized by an almost ballistic dynamic exponent $z \simeq 1.03(2)$ and arbitrarily slow velocities of growth. By contrast, for non-competing interactions the coarsening length scales are estimated to be almost diffusive.

description: This study aimed to visualize self-regulated learning (SRL) behaviors performed by users from an online teacher professional development platform called the EdHub Library using the pm4py algorithm in Python to parse event data during the first 30 days of the school year and the first 90 days of the COVID-19 pandemic in March 2020. Process mining techniques were implemented to visualize the user profiles of frequent users in case-based decompositions and identify critical SRL events and actions of all users in activity-based decompositions for three school years (2018, 2019, and 2020). SRL events and actions were measured for all pageviews.

description: The 3243A>G mutation in the MTTL1 (tRNALeu) gene and the 8344A>G mutation in the MTTK (tRNALys) gene are the most common mutations found in mitochondrial encephalomyopathy, lactic acidosis with stroke-like episodes and myoclonic epilepsy associated with ragged-red fibers, respectively. These mitochondrial DNA mutations are usually detected by conventional polymerase chain reaction followed by restriction enzyme digestion and gel electrophoresis. We developed a LightCycler real-time polymerase chain reaction assay to detect these two mutations based on fluorescence resonance energy transfer technology and melting curve analysis. Primers and fluorescence-labeled hybridization probes were designed so that the sensor probe spans the mutation site. The observed melting temperatures differed in the mutant and wild-type DNA by 9°C for the MTTL1 gene and 6°C for the MTTK gene. This method correctly identified all 10 samples that were 3243A>G mutation-positive, all 4 samples that were 8344A>G mutation-positive, and all 30 samples that were negative for both mutations, as previously identified by traditional gel-based methods. This LightCycler assay is a rapid and reliable technique for molecular diagnosis of these mitochondrial gene mutations.

description: Fluorescence in situ hybridization (FISH) provides an important adjunct to conventional cytogenetics and molecular studies in the evaluation of chromosome abnormalities associated with hematologic malignancies. FISH employs DNA probes and methods that are generally not Food and Drug Administration-approved, and therefore, their use as analyte-specific reagents involves unique pre- and postanalytical requirements. We provide an overview of the technical parameters influencing a reliable FISH result and encourage laboratories to adopt specific procedures and policies in implementing metaphase and interphase FISH testing. A rigorous technologist training program relative to specific types of probes is detailed, as well as guidance for consistent interpretation of findings, including typical and atypical abnormal results. Details are provided on commonly used dual-fusion, extra signal, and break-apart probes, correct FISH nomenclature in the reporting of results, and the use of FISH in relation to other laboratory testing in the ongoing monitoring of disease. This article provides laboratory directors detailed guidance to be used in conjunction with existing regulations to successfully implement a FISH testing program or to assess current practices, allowing for optimal clinical testing for patient care.
