Low copy expression vectors for use in Yersinia sp. and related organisms

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: In Yersinia, the most commonly used expression vectors for genetic studies such as gene complementation do not effectively allow for both induction and repression of gene expression. Additionally, there is no expression system available that can be induced in bacteria growing in vitro as well as in vivo, e.g. in eukaryotic cell lines or in living animal models. Here, we present a series of novel inducible low copy expression vectors that are well suited for use in the Yersinia species. Their tet operator/promoter/repressor system makes them distinct from other vectors, and gene transcription in bacteria can easily be induced by addition of anhydrotetracyline (ATc) either to the growth medium, to tissue culture medium during bacterial infections of cell lines or by injection into animals infected with bacteria. Researchers can choose between two different antibiotic resistances (kanamycin or spectinomycin), between two copy numbers (5 or 12-22) as well as between two different versions for expression from either the native RBS and ATG or RBS and ATG encoded in the plasmid. The whole vector series contains the same multi-cloning site from pBluescript II KS+ that allows for easy subcloning. Moreover, these vectors are built in a modular fashion that makes it simple to adapt them for other purposes. Finally, in addition to their use in Yersinia they are suitable for use in many other Enterobacteriaceae.

description: The 2019–2020 NBA season was altered significantly by the COVID-19 pandemic with a midseason suspension of games, the NBA ‘bubble’ tournament, and a shortened offseason. Concerns were raised regarding player conditioning and the potential increased risk of injury due to the schedule changes. The purpose of this study was to determine the impact of the COVID-19 pandemic and associated schedule changes on NBA injuries. It was hypothesized that injury rates would be higher in the year following the pandemic and teams who participated in the bubble would have higher injury rates in the following season than non-bubble teams. Furthermore, the types of injuries would shift toward more severe injuries in the condensed 2019–20 season and the following 2020–21 season. Retrospective Cohort Study The NBA’s public injury reports were queried to identify players listed on an injury report. Standardized injury events were calculated for four pre-COVID-19 seasons (2015–2019), the COVID-19 season (2019–2020), and the post-COVID-19 season (2020–2021). Injury characteristics including type and location were extracted for each year and differences within each period were calculated. When excluding injury events related to COVID-19 health and safety protocols, the overall injury events per 1000 exposures were not significantly different between time periods of pre-COVID-19, COVID-19, and post-COVID-19 seasons; (p = 0.199), and no difference was found in the rates of teams who participated in the bubble. Injuries, including soreness and strains, significantly decreased while fracture injuries significantly increased in the COVID-19 year. The COVID-19 pandemic led to an increased number of games missed, but no increase in injury rates when accounting for health and safety protocols. Additionally, bubble participation had no impact on injury rates. However, despite no changes in injury rates, the types of injuries changed with an increased proportion of severe injuries and decreased proportion of minor injuries.

description: We show and give the linear differential operators ${\cal L}^{scal}_q$ of order q= n^2/4+n+7/8+(-1)^n/8, for the integrals $I_n(r)$ which appear in the two-point correlation scaling function of Ising model $ F_{\pm}(r)= \lim_{scaling} {\cal M}_{\pm}^{-2} < σ_{0,0} \, σ_{M,N}> = \sum_{n} I_{n}(r)$. The integrals $ I_{n}(r)$ are given in expansion around r= 0 in the basis of the formal solutions of $\, {\cal L}^{scal}_q$ with transcendental combination coefficients. We find that the expression $ r^{1/4}\,\exp(r^2/8)$ is a solution of the Painlevé VI equation in the scaling limit. Combinations of the (analytic at $ r= 0$) solutions of $ {\cal L}^{scal}_q$ sum to $ \exp(r^2/8)$. We show that the expression $ r^{1/4} \exp(r^2/8)$ is the scaling limit of the correlation function $ C(N, N)$ and $ C(N, N+1)$. The differential Galois groups of the factors occurring in the operators $ {\cal L}^{scal}_q$ are given.

description: Credal sets are one of the most important models for describing probabilistic uncertainty. They usually arise as convex sets of probabilistic models compatible with judgments provided in terms of coherent lower previsions or more specific models such as coherent lower probabilities or probability intervals. In finite spaces, credal sets usually take the form of convex polytopes. Many properties of convex polytopes can be derived from their normal cones, which form polyhedral complexes called normal fans. We analyze the properties of normal cones corresponding to credal sets of coherent lower probabilities. For two important classes of coherent lower probabilities, 2-monotone lower probabilities and probability intervals, we provide a detailed description of the normal fan structure. These structures are related to the structure of the extreme points of the credal sets. To arrive at our main results, we provide some general results on triangulated normal fans of convex polyhedra and their adjacency structure.

description: The nature of Galactic interstellar extinction is tested using reddening line parameters for several fields in conjunction with equivalent widths $W(\lambda4430)$ for the diffuse interstellar band at $4430$ Å. The Cardelli et al.$\;$relations [29] at infrared, optical, and ultraviolet wavelengths are inconsistent with the newly-derived quadratic variation of $R_V({\rm observed})$ on reddening slope $X$. A minimum of $R_V=2.82\pm0.06$ exists for $X=0.83\pm0.10$, and is argued to represent true Galactic extinction described by $A(λ)\propto λ^{-1.375}$. It matches expectations for a new description of extinction in the infrared, optical, and ultraviolet by Zagury [32]. Additional consequences, reddened stars with no 2175 Å$\;$feature and a correlation of normalized $\lambda4430$ absorption with $X$, are not predicted by the Cardelli et al.$\;$relation [29]. Known variations in $X$ from 0.62 to 0.83, and corresponding variations in $R_V({\rm observed})$ from 4.0 to 2.8, presumably result from forward-scattered starlight in the ultraviolet contaminating optical light of stars affected by dust extinction. A new understanding of the true nature of interstellar extinction is important for establishing an accurate picture of the extragalactic distance scale, which in turn is related to our understanding of the nature of the Universe.

description: This work proposes a real-time anomaly detection scheme that leverages the multi-step ahead prediction capabilities of encoder-decoder (ED) deep learning models with recurrent units. Specifically, an encoder-decoder is used to model soft-failure evolution over a long future horizon (i.e., for several days ahead) by analyzing past quality-of-transmission (QoT) observations. This information is subsequently used for real-time anomaly detection (e.g., of attack incidents), as the knowledge of how the QoT is expected to evolve allows capturing unexpected network behavior. Specifically, for anomaly detection, a statistical hypothesis testing scheme is used, alleviating the limitations of supervised (SL) and unsupervised learning (UL) schemes, usually applied for this purpose. Indicatively, the proposed scheme eliminates the need for labeled anomalies, required when SL is applied, and the need for on-line analyzing entire datasets to identify abnormal instances (i.e., UL). Overall, it is shown that by utilizing QoT evolution information, the proposed approach can effectively detect abnormal deviations in real-time. Importantly, it is shown that the information concerning soft-failure evolution (i.e., QoT predictions) is essential to accurately detect anomalies.

description: Open systems with non-Hermitian degeneracies called exceptional points show a significantly enhanced response to perturbations in terms of large energy splittings induced by a small perturbation. This reaction can be quantified by the spectral response strength of the exceptional point. We extend the underlying theory to the general case where the dimension of the Hilbert space is larger than the order of the exceptional point. This generalization allows us to demonstrate an intriguing phenomenon: The spectral response strength of an exceptional point increases considerably and may even diverge to infinity under a parameter variation that eventually increases the order of the exceptional point. This dramatic behavior is in general not accompanied by a divergence of the energy eigenvalues and is shown to be related to the well-known divergence of Petermann factors near exceptional points. Finally, an accurate and robust numerical scheme for the computation of the spectral response strength based on the general theory and residue calculus is presented.

description: Perturbations to the cosmic baryon density - and thus to the total-matter density - can be induced by magnetohydronamic forces if there are primordial magnetic fields. The power spectrum for these density perturbations was first provided in 1996, but without much in the way of detail in the derivation, and there has been confusion in the intervening years about this calculation. In this brief note, we re-derive this power spectrum using modern conventions, provide a simplified result, and identify some of the discrepancies in the literature.

description: In this paper we consider the interrelation between compactified string theories on torus and gauge fields on it. We start from open string theories with background gauge fields and derive partition functions by path integral. Since the effects of background fields and compactification correlate only through string zero modes, we investigate these zero modes. From this point of view, we discuss the Wilson loop mechanism at finite temperature. For the closed string, only a few comments are mentioned.

description: We investigate whether and how the quantum Zeno effect, i.e., the inhibition of quantum evolution by frequent measurements, can be employed to isolate a quantum dot from its surrounding electron reservoir. In contrast to the often studied case of tunneling between discrete levels, we consider the tunnelling of an electron from a continuum reservoir to a discrete level in the dot. Realizing the quantum Zeno effect in this scenario can be much harder because the measurements should be repeated before the wave packet of the hole left behind in the reservoir moves away from the vicinity of the dot. Thus, the required repetition rate could be lowered by having a flat band (with a slow group velocity) in resonance with the dot or a sufficiently small Fermi velocity or a strong external magnetic field. We also consider the anti-Zeno effect, i.e., how measurements can accelerate or enable quantum evolution.

description: Groin injuries are common in soccer players and often involve adductor muscle strains. The Copenhagen Adduction Exercise (CAE) is a targeted intervention whose effectiveness in rehabilitation for these injuries warrants investigation. To investigate the impact of a rehabilitation program, which includes the CAE, on eccentric hip adduction (EHAD) strength, hip joint range of motion (ROM), self-reported disability, and pain among soccer players with adductor-related groin pain. It was hypothesized that the addition of CAE to the rehabilitation program would yield greater improvements. Employing a randomized controlled trial with a two-group parallel design, thirty male soccer players with a mean age of 26.4 ± 3.9 years were randomized into an intervention group (IG) including CAE (n = 15) and a control group (CG) without CAE (n = 15), based on a power analysis to ensure 80% power to detect significant differences. Both groups engaged in their respective rehabilitation programs twice a week for eight weeks. The primary outcome measured was EHAD strength, while secondary outcomes included hip joint ROM, self-reported disability measured by the Copenhagen Hip and Groin Outcome Score (HAGOS), and pain levels. Significant improvements within groups were observed across all measures (p < 0.001). The IG demonstrated a greater increase in EHAD strength (Mean Difference [MD] = 0.49 Nm/kg, 95% Confidence Interval [CI] [0.31, 0.66]), a more pronounced reduction in pain (MD = -1.60, 95% CI [−2.18, −1.02]), and betterment in all HAGOS subscale scores compared to the CG. There were no significant between-group differences in hip joint ROM. Incorporating the CAE into rehabilitation programs significantly improves EHAD strength, decreases pain scores, and reduces self-reported disability in soccer players with adductor-related groin pain.

description: Quantum search algorithm (also known as Grover's algorithm) lays the foundation for many other quantum algorithms. Although it is very simple, its implementation is limited on noisy intermediate-scale quantum (NISQ) processors. Grover's algorithm was designed without considering the physical resources, such as depth, in the real implementations. Therefore, Grover's algorithm can be improved for NISQ devices. In this paper, we demonstrate how to implement quantum search algorithms better on NISQ devices. We present detailed benchmarks of the five-qubit quantum search algorithm on different quantum processors, including IBMQ, IonQ, and Honeywell quantum devices. We report the highest success probability of the five-qubit search algorithm compared to previous works. Our results show that designing the error-aware quantum search algorithms is possible, which can maximally harness the power of NISQ computers.

description: Current efficacy data supporting the routine use of acellular dermal matrices (ADM) in postmastectomy tissue expander/implant reconstruction is limited. A multi-center, blinded, randomized controlled study was designed to evaluate the effectiveness of ADM in the setting of TE/I reconstruction. The primary objective of the study was to determine whether the use of ADM would decrease patient-reported, post-operative pain. The secondary objective was to determine whether the use of ADM accelerated the rate of post-operative expansion. Tertiary objectives included an evaluation of long-term aesthetic results, capsular contracture rates and patient satisfaction.

description: In this paper we use a Ginzburg-Landau approach to show that a suitably strong electric field can drive a phase transition from a superconductor to a normal metal. The transition is induced by taking into account corrections to the permittivity due to the superconductive gap and persists even when screening effects are considered. We test the model against recent experimental observations in which a strong electric field has been observed to control the supercurrent in superconducting thin films. We find excellent agreement with the experimental data and are able to explain several observed features. We additionally suggest a way to test our theoretical proposal via superconductor-superconductor electron tunneling.

description: Despite robust research endeavors exploring post-play health implications in former NFL players, the impact of former-player status on long-term cardiovascular health has not yet been elucidated. The purpose of this systematic review is to describe the available research on the cardiovascular health in former NFL players. Relevant studies were included from the PubMed, Scopus, and Embase databases. Studies were evaluated in accordance with PRISMA guidelines. Two independent reviewers conducted the title/abstract screenings and risk of bias determinations. The results of the studies were extracted for inclusion in the review. Sixteen studies met inclusion criteria. Though evidence was discordant among studies, former NFL players appeared to possess more favorable metabolic profiles and decreased mortality compared to community controls. Of note, 90% of former players were found to be overweight or obese. Though cardiovascular disease is the leading cause of death among former NFL players, they possess comparable metabolic and cardiovascular profiles to community controls. Further research is necessary to ascertain the impact of NFL play on cardiovascular health and develop tailored preventative care strategies for former players.

description: We construct clusters of bound particles for a quantum integrable derivative delta-function Bose gas in one dimension. It is found that clusters of bound particles can be constructed for this Bose gas for some special values of the coupling constant, by taking the quasi-momenta associated with the corresponding Bethe state to be equidistant points on a single circle in the complex momentum plane. Interestingly, there exists a connection between the above mentioned special values of the coupling constant and some fractions belonging to the Farey sequences in number theory. This connection leads to a classification of the clusters of bound particles for the derivative delta-function Bose gas and the determination of various properties of these clusters like their size and their stability under a variation of the coupling constant.

description: This paper presents findings from an institutional online survey investigating the use of WebCT by students in their learning and teaching at Monash University, Victoria. The survey was designed to ascertain how WebCT was being used, what support services were being utilised, and to determine what areas, if any, needed improvement. Based on anecdotal evidence, it was expected that most student comments would relate to technical and infrastructure issues, but instead, the survey elicited responses primarily on how WebCT was used in teaching and learning, indicating that quality control is a major issue for the University. Generally, students were positive about their use of WebCT and appear to have little trouble in using the technology. Student opinions appear to reflect more the use of the technology made by teaching staff - students who have experienced a well-designed unit rich with resources, timely feedback and good interaction with staff reporting a positive experience with the technology. However, there were equally negative responses from students about poorly designed sites, little or no feedback from staff, outdated information and broken links. The findings in this paper have implications for teaching and learning with technology and the way in which tertiary institutions support students using such technology.

description: We have performed resistivity measurements of poly[3,4-ethylenedioxythiophene]: poly[styrenesulfonate] (PEDOT:PSS) films with varying concentrations of glycerol. Resistivity is seen to decrease exponentially from roughly 3 ohm-cm for pure PEDOT:PSS to 3x10-2 ohm-cm for 35 mg/cm3 glycerol in PEDOT:PSS. Beyond this concentration adding glycerol does not significantly change resistivity. Bulk heterojunction polymer solar cells using these variously doped PEDOT:PSS layers as electrodes were studied to characterize the effects on efficiency and lifetime. Although our data display significant scatter, lowering the resistance of the PEDOT:PSS layers results in lower device resistance and higher efficiency as expected. We also note that the lifetime of the devices tends to be reduced as the glycerol content of PEDOT:PSS is increased. Many devices show an initial increase in efficiency followed by a roughly exponential decay. This effect is explained based on concomitant changes in the zero bias conductance of the samples under dark conditions.

description: The maximal values of the general relativistic Lense-Thirring (LT) orbital shifts $ΔI^\mathrm{LT},\,ΔΩ^\mathrm{LT}$ and $Δω^\mathrm{LT}$ of the inclination $I$, the longitude of the ascending node $Ω$ and the perinigricon $ω$ of the recently discovered star S4716, which has the shortest orbital period $\left(P_\mathrm{b}=4.02\,\mathrm{yr}\right)$ of all the S-stars that orbit the supermassive black hole (SMBH) in Sgr A$^\ast$, are of the order of $\simeq 5-16$ arcseconds per revolution $\left(^{\prime\prime}\,\mathrm{rev}^{-1}\right)$. Given the current error $σ_ω= 0.02^\circ$ in determining $ω$, which is the most accurate orbital parameter of S4716 among all those affected by the SMBH's gravitomagnetic field through its angular momentum ${\boldsymbol{J}}_\bullet$, about 48 yr would be needed to reduce $σ_ω$ to $\simeq 10\%$ of the cumulative LT perinigricon shift over the same time span. Measuring $ΔI^\mathrm{LT}$ and $ΔΩ^\mathrm{LT}$ to the same level of accuracy would take even much longer. Instead, after just 16 yr, a per cent measurement of the larger gravitoelectric (GE) Schwarzschild-like perinigricon shift $Δω^\mathrm{GE}$, which depends only on the SMBH's mass $M_\bullet$, would be possible. On the other hand, the uncertainties in the physical and orbital parameters entering $Δω^\mathrm{GE}$ would cause a huge systematic bias of $Δω^\mathrm{LT}$ itself. The SMBH's quadrupole mass moment $Q_2^\bullet$ induces orbital shifts as little as $\simeq 0.01-0.05\,^{\prime\prime}\,\mathrm{rev}^{-1}$.

description: We propose PARSE, a novel semi-supervised architecture for learning strong EEG representations for emotion recognition. To reduce the potential distribution mismatch between the large amounts of unlabeled data and the limited amount of labeled data, PARSE uses pairwise representation alignment. First, our model performs data augmentation followed by label guessing for large amounts of original and augmented unlabeled data. This is then followed by sharpening of the guessed labels and convex combinations of the unlabeled and labeled data. Finally, representation alignment and emotion classification are performed. To rigorously test our model, we compare PARSE to several state-of-the-art semi-supervised approaches which we implement and adapt for EEG learning. We perform these experiments on four public EEG-based emotion recognition datasets, SEED, SEED-IV, SEED-V and AMIGOS (valence and arousal). The experiments show that our proposed framework achieves the overall best results with varying amounts of limited labeled samples in SEED, SEED-IV and AMIGOS (valence), while approaching the overall best result (reaching the second-best) in SEED-V and AMIGOS (arousal). The analysis shows that our pairwise representation alignment considerably improves the performance by reducing the distribution alignment between unlabeled and labeled data, especially when only 1 sample per class is labeled.

description: There are currently no guidelines on peri-arthroscopic management of immunosuppressive (IS) treatment in rheumatic disease patients. The purpose of this study is to characterize the rheumatic disease patient population undergoing arthroscopy, compare the incidence of postoperative complications among patients who either remained on IS perioperatively, held IS perioperatively or were not on IS at baseline, and compare the incidence of postoperative complications by rheumatic disease type, medication type, and procedure. We conducted a retrospective review of all arthroscopic sports medicine surgeries in patients with a rheumatic disease diagnosis at our institution over an 11-year period. Patients on IS at baseline were grouped into those who remained on IS perioperatively or held all IS before the date of their surgery. These two groups were compared to patients who were not on IS at baseline. Incidence of postoperative complications was calculated for the three cohorts and by medication class, rheumatic disease type, and procedure risk. Analysis of variance (ANOVA), chi-squared, and Fisher’s exact tests were used to determine the statistical significance of between-group differences in postoperative complication incidence. We identified 1,316 rheumatic disease patients undergoing arthroscopy, with 214 of them taking IS medications at baseline. In total, 8.4% (n = 110) remained on IS perioperatively, 7.9% (n = 104) held IS perioperatively, and 83.7% (n = 1102) were not on IS at baseline. In all cohorts, seven patients experienced postoperative complications; six of whom experienced infections. Two (1.82%) occurred in patients remaining on IS perioperatively, zero infections occured in patients who held all IS, and four (0.36%) occured in patients who were not on any IS at baseline. There was no statistically significant difference in postoperative infections or complication rates among the three cohorts or further subgroups. The risk of postoperative complications including infectious, major, and minor complications in patients on IS at the time of arthroscopy is low and acceptable.

Fire safety engineering

description: Fire-exposed structures may collapse after the available fuel in the compartment has been consumed, while the enclosure is cooling or even after returning to ambient temperatures. But there is no standardized experimental method to study the stability of structural elements until full burnout. The standard fire testing method relies on continuous heating of the element to failure, and in some cases post-fire experiments measure residual load-bearing capacity, but neither of these methods assesses stability of loaded elements throughout the heating and cooling phases of a fire. This paper applies a new experimental method for evaluating the load-bearing capacity function of structural elements until fire burnout. The method adopts the Duration of Heating Phase (DHP) indicator for assessing the burnout resistance of the elements. Full-scale furnace tests on loaded columns are presented, including four on reinforced concrete columns and eight on timber columns, in which identical specimens were subjected to various heating durations followed by controlled cooling. For both the concrete and timber columns, failures occurred during the cooling phase after exposure to ISO 834 heating for a duration shorter than their fire resistance. The timber columns had a measured fire resistance of 55-58 minutes (two specimens) but, when exposed to heating for 15 minutes, failed during cooling after 98-153 minutes (two specimens). These experiments show that delayed thermal-mechanical effects can jeopardize structural stability in real fires and provide a systematic method to assess these effects.

description: Magnetic imaging using nitrogen-vacancy (NV) spins in diamonds is a powerful technique for acquiring quantitative information about sub-micron scale magnetic order. A major challenge for its application in the research on two-dimensional (2D) magnets is the positioning of the NV centers at a well-defined, nanoscale distance to the target material required for detecting the small magnetic fields generated by magnetic monolayers. Here, we develop a diamond 'dry-transfer' technique, akin to the state-of-the-art 2D-materials assembly methods, and use it to place a diamond micro-membrane in direct contact with the 2D interlayer antiferromagnet CrSBr. We harness the resulting NV-sample proximity to spatially resolve the magnetic stray fields generated by the CrSBr, present only where the CrSBr thickness changes by an odd number of layers. From the magnetic stray field of a single uncompensated ferromagnetic layer in the CrSBr, we extract a monolayer magnetization of $M_\mathrm{CSB}$ = 0.46(2) T, without the need for exfoliation of monolayer crystals or applying large external magnetic fields. The ability to deterministically place NV-ensemble sensors into contact with target materials and detect ferromagnetic monolayer magnetizations paves the way for quantitative analysis of a wide range of 2D magnets assembled on arbitrary target substrates.

description: Dyspnea is a critical component of chronic obstructive pulmonary disease (COPD). We report the effect of ensifentrine, a novel PDE3/PDE4 inhibitor, on dyspnea using pooled data from the Phase 3 ENHANCE-1/2 trials. The pooled population (ensifentrine, n = 975; placebo, n = 574) included patients aged 40–80 years with post-bronchodilator FEV1/FVC <0.7, FEV1 30–70% predicted, mMRC Dyspnea Scale score ≥2, and a smoking history ≥10 pack-years. Patients taking dual LAMA/LABA or LAMA/LABA/ICS triple therapy were excluded. Dyspnea measures included the Transition Dyspnea Index (TDI), Evaluating Respiratory Symptoms (E-RS), and rescue medication use. After 24 weeks, ensifentrine significantly improved TDI scores (least-squares mean difference, 0.97; 95% CI, 0.64, 1.30; p < 0.001) and across all TDI subdomains. Ensifentrine-treated patients were more likely to be TDI responders at week 24 (p < 0.001), which was consistent across clinically relevant subgroups. Ensifentrine-treated patients had improved E-RS breathlessness subdomain scores (p = 0.053) and reduced rescue medication use (p = 0.002). Ensifentrine produced clinically meaningful improvements in multiple dyspnea measures in patients with symptomatic, moderate-to-severe COPD. A limitation of this study was the exclusion of patients taking dual LAMA/LABA and LAMA/LABA/ICS triple therapy. www.clinicaltrials.gov identifiers are ENHANCE-1: NCT04535986; ENHANCE-2: NCT04542057.
