description: Exchange Server is a platform for email, calendaring, contact management, scheduling, and collaboration. It's designed for use in business or education and runs on the Windows Server operating system. Exchange Server is designed to allow users to access the messaging platform from mobile devices, desktop computers, and web-based systems. Voice messages are supported by Exchange Server's telephony features. Users of Exchange can collaborate by exchanging calendars and documents. Organizations can use the platform's storage and security features. Exchange Server has evolved over time, and it is now a foundational component of Office 365 as a software as a service (SaaS) offering in the Microsoft cloud with Microsoft acting as the service provider. Exchange Server is noted for its high availability (HA) features, which ensure that service is maintained in the event of a failure. This covers the routes for design. Database availability groups (DAGs) were initially introduced in Exchange 2010 and rapidly became one of Exchange's most essential subsystems. When an Exchange server joins a DAG, it runs two AM roles: Primary Active Manager (PAM) and Standby Active Manager (SAM) (SAM). The PAM role will be held by the DAG member server that holds the cluster quorum resource. The PAM role will be moved to the server that acquires ownership of the quorum resource if the DAG node that has the quorum resource fails. The SAM is in charge of informing other Exchange components that execute AM clients about which database copy is active at any given time. We'll keep the exchange server but with a different approach. In any corporation, encryption and digital certificates are critical issues. By default, Exchange Server encrypts communication between internal Exchange servers and between Exchange services on the local server using Transport Layer Security (TLS). Exchange administrators must, however, examine their encryption requirements for internal and external clients (computers and mobile devices) as well as external messaging servers. We can also utilize Clearswift Secure Exchange Gateway (SXG) to prevent vital information from being exchanged via internal email and then exiting a business. Organizations can adhere to security and compliance standards by detecting malware, suspicious scripts, and identifying sensitive data in messages and attachments based on readily created policy-based procedures.

description: Experimental findings of CMS on properties of jets and underlying events at high multiplicities in proton-proton interactions at 7 TeV are interpreted as an indication of increasing role of central collisions with small impact parameters. We find an indication that the rates of different hard processes observed by CMS and ALICE universally depend on underlying event charged-particles multiplicity until it becomes four times more than average. It is shown that the increase of the overlap area of colliding protons is not sufficient for explanation of the rate of jet production in events with charged-particle multiplicity three times higher than average and some new mechanisms are necessary like interaction of protons in rare configurations of higher than average gluon density. Such mechanisms are not included in the present Monte Carlo event generators. Further studies are proposed

description: Although depression symptoms are associated with an increased risk of recurrent cardiovascular disease in patients who have experienced an acute coronary syndrome (ACS) event, the exact mechanisms remain poorly understood. Inflammation has been suggested to be a mechanism in the depression–ACS prognosis link, as raised concentrations of inflammatory biomarkers, especially C reactive protein (CRP), are associated with recurrent cardiovascular events.1 In the few studies that have examined the relation between depression status and CRP concentrations after an ACS event, depression and CRP concentrations were assessed 2–6 months after the index ACS event, when the rate of depression remission would already be relatively high.2–4 The objective of this study was to examine the relation between the course of depression and CRP concentrations after an ACS event.

description: We report two-photon excited fluorescence of dyes for refracted laser beams by utilizing tailored laser pulses. A fluorescence contrast difference due to phase shaping could be achieved between different coumarin dyes. Particularly, an increased contrast difference is obtained for configurations close to the Brewster angle. Furthermore, by using a subsequent deformable phase plate for spatial shaping it was possible to precisely adjust the laser beam for controlled refraction at the liquid dye surface. A polarization-dependent refraction was observed when directing the shaped laser beam on the curved liquid adhesion meniscus close to the cuvette wall. This results in a refraction-dependent contrast difference. The presented method could be utilized for surface-sensitive biophotonic imaging applications.

description: OBJECTIVE Compare differences in health-related quality of life among blacks and whites to examine if race, diabetes, and visual impairment (VI) present a triple disadvantage in terms of quality-adjusted life expectancy.

RESEARCH DESIGN AND METHODS Data were analyzed from the 2000–2003 Medical Expenditure Panel Survey, a nationally representative survey that contains the EuroQol 5D (EQ-5D). The EQ-5D generates health utility values that provide a measure of the morbidity associated with various health states, such as having moderate or severe problems with mobility. The EQ-5D score can be linked with life expectancy data to calculate quality-adjusted life-years (QALYs), the number of years of optimal health an individual is expected to live. Multivariate analyses were conducted to estimate and compare differences in QALYs by diabetes status, VI status, and race.

RESULTS Whites had a higher quality-adjusted life expectancy across all diabetes/VI comparisons. Overall, blacks with diabetes and VI had the fewest number of QALYs remaining (19.6 years), and whites with no impairment had the greatest number of QALYs remaining (31.6 years). Blacks with diabetes only had 1.7 fewer years of optimal health (fewer QALYs) than whites with diabetes. Within individuals with both diabetes and VI, however, this gap more than doubled, with blacks experiencing 3.5 fewer QALYs than whites.

CONCLUSIONS Although efforts to target and reduce racial health disparities associated with diabetes appear to be effective, black communities may be contributing to a greater overall burden of illness given poorer infrastructure and less accommodation for disabilities such as VI.
title: Semantic and distributional patterns of Spanish negation with nouns and adjectives: A Lexical-Realizational Functional Grammar approach

description: This study examines the semantic and distributional characteristics of the Spanish negation no when it occurs before nouns and adjectives, specifically, whether these instances diverge from sentential negation, but also from negation via prefixes such as des- ‘dis-’ or in- ‘in-, un-’. Using data from the Spanish Web 2011 corpus, it is shown that the use of no before adjectives aligns with other forms of constituent negation, often resulting in a contradictory interpretation, that is similar to that of sentential negation. However, the interpretation of no preceding nouns exhibits a broader range of interpretations, depending on whether the noun refers to an eventuality, quality, or entity. In such instances, no shows parallels to negative prefixes, frequently indicating privation rather than contradiction. Consequently, no can be analyzed as a building block of phrases, expressing syntactic negation, behaving similarly to other adverbs, as well as a building block of words, expressing lexical negation, resembling Spanish prefix-like elements like cuasi ‘almost’ or ex ‘ex-’. The analysis is couched within the framework of Lexical-Realizational Functional Grammar (LRFG), integrating aspects of Lexical Functional Grammar and Distributed Morphology. This approach does not treat morphology and syntax as separate modules, thus allowing us to account for the variable distribution and interpretation of no by means of a single representation in vocabulary structure, drawing on constituent structure representations which are needed on independent grounds for adverbs and for prefix-like elements.

description: Anger is an independent predictor of coronary heart disease events, although the mechanisms for this relation are unclear. The effects of an anger-provoking interview compared with a neutral interview on endothelium-dependent and -independent vasodilation assessed by brachial artery ultrasound were examined in 14 healthy subjects without coronary heart disease risk factors. The anger provocation condition, but not the neutral condition, caused a significant impairment in endothelium-dependent vasodilation at 90 minutes compared with baseline (p = 0.004) and 30 minutes (p = 0.013). Similarly, endothelium-independent vasodilation was significantly impaired at 90 minutes after the angry interview compared with baseline (p = 0.003) and 30 minutes (p = 0.001). The decreases in endothelium-dependent and -independent vasodilation were greater after the anger-provoking interview than after the neutral interview, especially between 30 and 90 minutes. In conclusion, preliminary results suggest that an episode of anger is associated with a dysregulation in endothelium-dependent and -independent pathways, suggesting that these mechanisms might contribute to the link between anger and coronary heart disease events.

Although anger is associated with increased short- and long-term risk for coronary heart disease (CHD) events, independent of traditional CHD risk factors,1, 2, 3, 4, 5 and 6 the mechanisms that underlie this relation are unknown. Endothelial dysfunction plays a major role in the development of atherosclerosis.7 Traditional CHD risk factors are associated with endothelial dysfunction8 and may also impair arterial vasodilation in response to exogenous nitric oxide (NO), suggesting concomitant vascular smooth muscle dysfunction.8 and 9 Thus, the higher risk for CHD events associated with anger may be similarly mediated through an impairment in endothelium-dependent vasodilation (EDV) with or without an impairment in endothelium-independent vasodilation (EIV). To our knowledge, the effects of anger on EDV and EIV have never previously been examined. To test this hypothesis, we examined the effects of anger induction in humans on EDV and EIV assessed by brachial artery ultrasonography.
Conification construction for Kaehler manifolds and its application in c-projective geometry

description: Two Kaehler metrics on one complex manifold are said to be c-projectively equivalent if their J-planar curves, i.e., curves defined by the property that their acceleration is complex proportional to their velocity, coincide. The degree of mobility of a Kaehler metric is the dimension of the space of metrics that are c-projectively equivalent to it. We give the list of all possible values of the degree of mobility of simply connected 2n-dimensional Riemannian Kaehler manifolds. We also describe all such values under the additional assumption that the metric is Einstein. As an application, we describe all possible dimensions of the space of essential c-projective vector fields of Kaehler and Kaehler-Einstein Riemannian metrics. We also show that two c-projectively equivalent Kaehler Einstein metrics (of arbitrary signature) on a closed manifold have constant holomorphic curvature or are affinely equivalent.

description: Relative variations in the number of sunspots and sunspot groups in activity cycles have been analyzed based on data from the Kislovodsk Mountain Astronomical Station and international indices. The following regularities have been established: (1) The relative fraction of small sunspots decreases linearly and that of large sunspots increase with increasing activity cycle amplitude. (2) The variation in the average number of sunspots in one group has a trend, and this number decreased from 12 in cycle 19 to 7.5 in cycle 24. (3) The ratio of the sunspot index (Ri) to the sunspot group number index (Ggr) varies with a period of about 100 years. (4) An analysis of the sunspot group number index (Ggr) from 1610 indicates that the Gnevyshev-Ohl rule reverses at the minimums of secular activity cycles. (5) The ratio of the total sunspot area to the umbra area shows a long-term variation with a period about eight cycles and minimum in cycles 16-17. (6) It has been indicated that the magnetic field intensity and sunspot area in the current cycle are related to the amplitude of the next activity cycle.

description: Very little is known about the newest New Yorkers of Chinese heritage, the largest and fastest growing immigrant group in the city. This article compares measures of the health of immigrants to New York from Mainland China to the health of other New Yorkers of Asian heritage along with all other New Yorkers. We did so using the 1,999 subjects in the 2004 New York Health and Nutrition Examination Survey, controlling for age and gender. We found that New Yorkers born in Mainland China have a lower body mass index, a smaller waist circumference, a more sexually conservative lifestyle, highly favorable high-density lipoprotein profiles, and lower rates of herpes II infection. However, they also have higher blood levels of lead, cadmium, and mercury than either reference group. This article provides the first study of the health needs of New York's largest and most rapidly growing immigrant group.
Abstract Phase-space Networks Describing Reactive Dynamics

description: An abstract network approach is proposed for the description of the dynamics in reactive processes. The phase space of the variables (concentrations in reactive systems) is partitioned into a finite number of segments, which constitute the nodes of the abstract network. Transitions between the nodes are dictated by the dynamics of the reactive process and provide the links between the nodes. These are weighted networks, since each link weight reflects the transition rate between the corresponding states-nodes. With this construction the network properties mirror the dynamics of the underlying process and one can investigate the system properties by studying the corresponding abstract network. As a working example the Lattice Limit Cycle (LLC) model is used. Its corresponding abstract network is constructed and the transition matrix elements are computed via Kinetic (Dynamic) Monte Carlo simulations. For this model it is shown that the degree distribution follows a power law with exponent -1, while the average clustering coefficient $c(N)$ scales with the network size (number of nodes) $N$ as $c(N)\sim N^{-ν}, ν\simeq 1.46$. The computed exponents classify the LLC abstract reactive network into the scale-free networks. This conclusion corroborates earlier investigations demonstrating the formation of fractal spatial patterns in LLC reactive dynamics due to stochasticity and to the clustering of homologous species. The present construction of abstract networks (based on the partition of the phase space) is generic and can be implemented with appropriate adjustments in many dynamical systems and in time series analysis.

description: It has recently been established that open quantum systems may exhibit a strong spectral sensitivity to boundary conditions, known as the non-Hermitian/Liouvillian skin effect (NHSE/LSE), making the topological properties of the system boundary-condition sensitive. In this Letter, we ask the query: Can topological phase transitions of open quantum systems, captured by open boundary conditioned invariants, be observed in the dynamics of a system in a periodic boundary condition, even in the presence of NHSE/LSE? We affirmatively respond to this question, by considering the quench dynamics of entanglement spectrum in a periodic open quantum fermionic system. We demonstrate that the entanglement spectrum exhibits zero-crossings only when this periodic system is quenched from a topologically trivial to non-trivial phase, defined from the spectrum in open boundary conditions, even in systems featuring LSE. Our results reveal that non-Hermitian topological phases leave a distinctive imprint on the unconditional dynamics within a subsystem of fermionic systems.

description: Background:
 Several ambulatory blood pressure monitoring (ABPM) measures have been associated with increased cardiovascular disease risk independent of clinic blood pressure (BP). African Americans have higher clinic BP compared with Whites but few data are available on racial differences in ABPM measures.

Methods:
We compared ABPM measures between African American (n = 178) and White (n = 103) participants at the Year 5 Coronary Artery Risk Development in Young Adults study visit. BP was measured during a study visit and the second and third measurements were averaged. ABPM was conducted over the following 24 hours.

Results:
 Mean ± SD age of participants was 29.8±3.8 years and 30.8±3.5 years for African Americans and Whites, respectively. Mean daytime systolic BP (SBP) was 3.90 (SD 1.18) mm Hg higher among African Americans compared with Whites (P < 0.001) after age–gender adjustment and 1.71 (SD 1.03) mm Hg higher after multivariable adjustment including mean clinic SBP (P = 0.10). After multivariable adjustment including mean clinic SBP, nighttime SBP was 4.83 (SD 1.11) mm Hg higher among African Americans compared with Whites (P < 0.001). After multivariable adjustment, the African Americans were more likely than Whites to have nocturnal hypertension (prevalence ratio: 2.44, 95% CI: 0.99–6.05) and nondipping (prevalence ratio: 2.50, 95% CI: 1.39–4.48). The prevalence of masked hypertension among African Americans and Whites was 4.4% and 2.1%, respectively, (P = 0.49) and white coat hypertension was 3.3% and 3.9%, respectively (P = 0.99). Twenty-four hour BP variability on ABPM was higher among African Americans compared with Whites.

Conclusions:
These data suggest racial differences in several ABPM measures exist.

description: This article investigates the causality structure of financial time series. We concentrate on three main approaches to measuring causality: linear Granger causality, kernel generalisations of Granger causality (based on ridge regression and the Hilbert--Schmidt norm of the cross-covariance operator) and transfer entropy, examining each method and comparing their theoretical properties, with special attention given to the ability to capture nonlinear causality. We also present the theoretical benefits of applying non-symmetrical measures rather than symmetrical measures of dependence. We apply the measures to a range of simulated and real data. The simulated data sets were generated with linear and several types of nonlinear dependence, using bivariate, as well as multivariate settings. An application to real-world financial data highlights the practical difficulties, as well as the potential of the methods. We use two real data sets: (1) U.S. inflation and one-month Libor; (2) S$\&$P data and exchange rates for the following currencies: AUDJPY, CADJPY, NZDJPY, AUDCHF, CADCHF, NZDCHF. Overall, we reach the conclusion that no single method can be recognised as the best in all circumstances, and each of the methods has its domain of best applicability. We also highlight areas for improvement and future research.

description: Abstract

Technological development, online platforms and remote services are directly related to innovations in the financial industry. All above mentioned in turn increases quantitative and qualitative operational risks and the likelihood of bankruptcy. Despite the risks, banks are constantly trying to offer customers innovative products and services. Based on the experience of foreign countries, they use electronic technology services. Loyalty programs increase customer satisfaction and bank income. Premium services and privileged position are especially important for business people who have a solid financial situation and do not have enough time to manage personal matters. Customers using premium services are characterized by loyalty, trust and long-term relationships with the serving bank. The goal of loyalty programs in the short term is to increase the bank's awareness among the population, and in the long term to attract new customers and retain existing customers. True loyalty on the part of the customer means that the customer remains loyal to the bank serving them despite the better offer by a competing bank. Customer loyalty is influenced by: age, geographical location, gender, nationality, income, etc.

However, relatively little work has been done on how such affordability standards should be set. The existing literature on affordability is not grounded in social norms and has methodological and theoretical flaws. To address these issues, we developed a series of hypothetical vignettes in which individual and household sociodemographic characteristics were varied. We then convened a panel of eighteen experts with extensive experience in affordability standards to evaluate the extent to which each vignette character could afford to pay for one of two health insurance plans. The panel varied with respect to political ideology and discipline. We find that there was considerable disagreement about how affordability is defined. There was also disagreement about what might be included in an affordability standard, with substantive debate surrounding whether savings, debt, education, or single parenthood is relevant. There was also substantial variation in experts' assessed affordability scores. Nevertheless, median expert affordability assessments were not far from those of ACA.

description: A novel method of analysis of double-lined eclipsing binaries containing a radially pulsating star is presented. The combined pulsating-eclipsing light curve is built up from a purely eclipsing light curve grid created using an existing modeling tool. For every pulsation phase the instantaneous radius and surface brightness are taken into account, being calculated from the disentangled radial velocity curve of the pulsating star and from its out-of-eclipse pulsational light curve and the light ratio of the components, respectively. The best model is found using the Markov Chain Monte Carlo method. The method is applied to the eclipsing binary Cepheid OGLE-LMC-CEP-0227 (P_puls = 3.80 d, P_orb = 309 d). We analyze a set of new spectroscopic and photometric observations for this binary, simultaneously fitting OGLE V-band, I-band and Spitzer 3.6 μm photometry. We derive a set of fundamental parameters of the system significantly improving the precision comparing to the previous results obtained by our group. The Cepheid mass and radius are M_1 = 4.165 +/- 0.032 M_solar and R_1 = 34.92 +/- 0.34 R_solar, respectively. For the first time a direct, geometrical and distance-independent determination of the Cepheid projection factor is presented. The value p = 1.21 +/- 0.03(stat.) +/- 0.04(syst.) is consistent with theoretical expectations for a short period Cepheid and interferometric measurements for δ Cep. We also find a very high value of the optical limb darkening coefficients for the Cepheid component, in strong disagreement with theoretical predictions for static atmospheres at a given surface temperature and gravity.

description: 5-Methylcytosine (5mC) is a central epigenetic mark of mammalian DNA. It mainly occurs in cytosine-guanine (CpG) dinucleotides and is recognized competitively by methyl-CpG binding domain (MBD) proteins and ten-eleven-translocation (TET) dioxygenases, which act as methylation readers and erasers to mediate regulatory chromatin crosstalk and epigenome editing, respectively. The dynamic reader-eraser interplay at their common substrate is therefore highly regulated for a coherent transcriptional program. However, mechanistic insights of their interplay are hampered by a lack of suitable methodology to control their activities in living cells. This work employs light-activatable human TET1 and MBD1 to enable precise temporal control of enzymatic oxidation activity or substrate recognition. Light activation is achieved by genetic encoding of a photocaged serine that can be co-translationally incorporated at critical protein sited in mammalian cells. On the one hand, monitoring the TET1-catalyzed 5mC oxidation kinetics in vivo reveals a multifaceted domain-dependent modulation by MBD1. While the MBD domain of MBD1 negatively regulates TET1 oxidation kinetics and dominates the interplay by competing for the 5mC substrates, the third Cys-x-x-Cys (CXXC3) domain of MBD1 contrarily modulates TET1 activity by binding to nonmethylated CpGs. Intriguingly, the transcriptional repressor domain (TRD) does not influence 5mC oxidation kinetics by TET1. On the other hand, studies with light-activatable MBD1 indicate a domain-dependency of cellular mCpG binding kinetics. Depriving the nonmethylated CpG affinity of the CXXC3 domain enhances binding kinetics, whereas the absence of the TRD domain results in decreased binding kinetics. Moreover, the light-activatable MBD1 can further unveil the mechanism of MBD1-TET1 interplay by uncoupling the process from prior binding events of MBD1. Collectively, this work enables first kinetic insights into the domain-dependent interplay of methylation readers and erasers in the natural chromatin context and provides novel tools to unravel the dynamic chromatin regulation program.

description: Solid-state quantum registers consisting of optically active electron spins with nearby nuclear spins are promising building blocks for future quantum technologies. For electron spin-1 registers, dynamical decoupling (DD) quantum gates have been developed that enable the precise control of multiple nuclear spin qubits. However, for the important class of electron spin-1/2 systems, this control method suffers from intrinsic selectivity limitations, resulting in reduced nuclear spin gate fidelities. Here we demonstrate improved control of single nuclear spins by an electron spin-1/2 using Dynamically Decoupled Radio Frequency (DDRF) gates. We make use of the electron spin-1/2 of a diamond tin-vacancy center, showing high-fidelity single-qubit gates, single-shot readout, and spin coherence beyond a millisecond. The DD control is used as a benchmark to observe and control a single carbon-13 nuclear spin. Using the DDRF control method, we demonstrate improved control on that spin. In addition, we find and control an additional nuclear spin that is insensitive to the DD control method. Using these DDRF gates, we show entanglement between the electron and the nuclear spin with 72(3)% state fidelity. Our extensive simulations indicate that DDRF gate fidelities well in excess are feasible. Finally, we employ time-resolved photon detection during readout to quantify the hyperfine coupling for the electron's optically excited state. Our work provides key insights into the challenges and opportunities for nuclear spin control in electron spin-1/2 systems, opening the door to multi-qubit experiments on these promising qubit platforms.

description: Background. Early education interventions have been forwarded as a means for reducing social disparities in income and health in adulthood. We explore whether a successful early education intervention, which occurred between 1985 and 1989, improved the employment rates, earnings and health of blacks relative to whites through 2008. Methods. We used data from Project STAR (Student Teacher Achievement Ratio), a four-year multi-center randomized controlled trial of reduced class sizes in Tennessee involving 11,601 students. Students were initially randomized within 79 schools to classes with 22-25 or 13-17 students. We linked subject records to Social Security Administration (SSA) earnings and disability data collected between 1997 and 2008—when the majority of subjects were between the ages of 18 and 28. We focused our analysis on annual, rather than cumulative, measures of earnings and employment because educational attainment after high school might reduce earnings through age 23. We considered three or more years of statistically significant positive (or negative) annual impacts to be a meaningful effect. Results. Project STAR improved cognition and high school graduation rates. These benefits were primarily realized among low-income and minority students. These early education benefits did not translate into reduced disability claims in adulthood for treated subjects. However, exposure to small class size increased employment for blacks, and increased earnings for black males (p<0.05). Exposure to small classes also led to an increase in earnings for white males. However, white females exposed to small classes experienced a net decline in earnings and employment across the later years of follow up (p<0.05), offsetting any gains by white males. Conclusions. Exposure to small class size in grades K-3 appears to improve earnings and employment for black males and earnings for white males, while reducing employment and earnings among white females.
Constraining a multiple stellar origin of blue stragglers via speckle imaging

description: As single stellar evolution cannot explain the existence of blue stragglers (BSs), several formation scenarios involving binaries have been put forward, with mass transfer and direct collisions taking the lead. A third mechanism, operating on its own or enhancing the former, is the Kozai-Lidov mechanism, where the amplitude of the inner binary in a hierarchical triple system, changes via secular torque of its outer companion, eventually leading to a merger of the inner binary and the formation of a BS. While much of our knowledge of the binarity of BSs comes from multi-year radial velocity campaigns (e.g. WOCS), these approaches are necessarily insensitive to the most distant binaries, like those predicted by the Kozai-Lidov mechanism. These companions on wide orbits may be visible through direct high-resolution imaging. We observed 51 BSs in 10 open clusters with the speckle interferometers, Zorro and 'Alopeke at both Gemini telescopes, reaching a spatial resolution of about 25 mas, the diffraction limit at ~500nm. Our observations probe for main-sequence companions down to a mass close to 0.4 Msun, revealing that about 10% of BSs have these distant main-sequence companions. On-going spectroscopy will reveal whether the companions can be considered bound.

description: The degradation and metabolism of antibiotics have attracted the scientific community's attention due to the environmental problems caused by the inappropriate use and disposal of these drugs. Therefore, it is crucial to understand the reaction mechanism involved in the degradation of these compounds. We studied the hydrolysis of nitrocefin and benzylpenicillin, two β-lactam ring antibiotics, mediated by an enzymatic mimetic Zn organometallic compound, using DFT methods. The electronic effects of functional groups adjacent to the β-lactam ring were analysed and good agreement between experimental and theoretical results was found. The reaction involves the nucleophilic attack of the bridging hydroxide group on the Zn atoms towards the β-lactam ring. A stepwise mechanism was found to agree with the experimental results. Chemical hardness profiles were affected by the solvent and reaction synchronicity. Geometric rearrangements dominated the activation barrier, and both antibiotics exhibited late transition states.
