description: Adolescent girls and young women (AGYW) in sub-Saharan Africa are at high risk of many adverse sexual and reproductive health outcomes. Small-group interventions addressing underlying vulnerabilities may influence risky sexual behaviors associated with these adverse outcomes. Girl Power-Malawi assessed whether a facilitator-led, curriculum-driven small-group behavioral intervention impacted risky sexual behaviors among AGYW in Lilongwe, Malawi. Four Health Centers were selected; two were randomly assigned to provide the intervention. Two-hundred fifty AGYW 15–24 years old were enrolled in each clinic (N = 1000 total), followed for 1 year, and interviewed at baseline and endline. At both time points participants reported on two behaviors in the last month (vaginal sex and ≥ 2 sexual partners) and two behaviors in the last year (age-disparate relationships and transactional relationships). In intervention clinics, there were no declines in risk behaviors between baseline and endline. Endline behaviors were not less risky in intervention clinics than control clinics. This intervention did not have a positive effect on four risk behaviors over a 1-year period.

description: Transactional sex (TS) has been shown to contribute to the HIV epidemic in sub-Saharan Africa. Previous research has yet to identify psychosocial factors that make young women vulnerable to engaging in TS. This analysis examined the association between self-esteem and TS among young women in rural South Africa. A post hoc analysis of post-intervention survey data from HPTN 068 was conducted. Log-binomial regression was used to compute a prevalence ratio measure of association. Among 1942 young women, the prevalence of TS among those with lower self-esteem was 4.7 times the prevalence of TS among those with higher self-esteem (p < 0.001). Findings provide support for the association between lower self-esteem and TS in this context and may inform intervention development.

description: Optical or electrical stimulation of neural circuits in mice during natural behavior is an important paradigm for studying brain function. Conventional systems for optogenetics and electrical microstimulation require tethers or large head-mounted devices that disrupt animal behavior. We report a method for wireless powering of small-scale implanted devices based on the strong localization of energy that occurs during resonant interaction between a radio-frequency cavity and intrinsic modes in mice. The system features self-tracking over a wide (16 cm diameter) operational area, and is used to demonstrate wireless activation of cortical neurons with miniaturized stimulators (10 mm$^{3}$, 20 mg) fully implanted under the skin.

description: We propose a model for the dynamics of a probe embedded in a living cell, where both thermal fluctuations and nonequilibrium activity coexist. The model is based on a confining harmonic potential describing the elastic cytoskeletal matrix, which undergoes random active hops as a result of the nonequilibrium rearrangements within the cell. We describe the probe's statistics and we bring forth quantities affected by the nonequilibrium activity. We find an excellent agreement between the predictions of our model and experimental results for tracers inside living cells. Finally, we exploit our model to arrive at quantitative predictions for the parameters characterizing nonequilibrium activity, such as the typical time scale of the activity and the amplitude of the active fluctuations.

description: The first truly non-MHV interaction vertices in the light-cone formulation of pure gravity appear at order 6. From a closed form expression, for gravitation in the light-cone gauge, we extract and present all 6-point interaction vertices. We invoke symmetry arguments to explain the structure of these vertices. Symmetry considerations also allow us to place constraints on the structure of all even- and odd-point vertices in the theory. The origin of MHV vertices within this formalism is also discussed.

description: The production cross sections of the B+, B0, and B0s mesons, and of their charge conjugates, are measured via exclusive hadronic decays in pPb collisions at the center-of-mass energy sqrt(s_NN) = 5.02 TeV with the CMS detector at the CERN LHC. The data set used for this analysis corresponds to an integrated luminosity of 34.6 inverse nanobarns. The production cross sections are measured in the transverse momentum range between 10 and 60 GeV/c. No significant modification is observed compared to proton-proton perturbative QCD calculations scaled by the number of incoherent nucleon-nucleon collisions. These results provide a baseline for the study of in-medium b quark energy loss in PbPb collisions.

description: This research project aimed to elicit the views of children and young people (CYP) about their experience of COVID-19, and their advice to teachers and schools. The views of fourteen CYP aged between 9 and 15 years of age from within and around London were ascertained through individual semi-structured interviews and analysed through thematic analysis. There were a variety of responses from CYP, including the following: a deep appreciation for their teachers and their support throughout the pandemic; stories of positive personal growth and spending more time with their family. However, their inability to see friends and the challenges of learning from home had a considerable impact on some CYP who would have liked home learning to have been more personalised, interactive and varied and for there to have been a greater awareness of workload. A list of issues for consideration and a checklist based upon the CYP’s views have been compiled, for the use of schools and teachers. Given the small sample, the timing of the study and the fact that the pandemic is ongoing, some suggestions for further research are indicated.

description: We use the HB morphology of 48 Galactic GCs to study the radial distributions of the different stellar populations known to exist in globular clusters. Assuming that the (extremely) blue HB stars correspond to stars enriched in Helium and light elements, we compare the radial distributions of stars selected according to colour on the HB to trace the distribution of the secondary stellar populations in globular clusters. Unlike other cases, our data show that the populations are well mixed in 80% of the cases studied. This provides some constraints on the mechanisms proposed to pollute the interstellar medium in young globular clusters.

description: Adolescent girls and young women (AGYW) ages (15–24 years old) in Southern and Eastern Africa account for nearly 30% of all new HIV infections. We conducted a systematic review of studies examining the effectiveness of behavioral, structural, and combined (behavioral + structural) interventions on HIV incidence and risky sexual behaviors among AGYW. Following PRISMA guidelines, we searched PubMed, CINAHL, Web of Science, and Global Health. Twenty-two studies met inclusion criteria conducted in Eastern and Southern Africa and comprised behavioral, structural, or combined (behavioral and structural) interventions. All findings are based on 22 studies. HIV incidence was significantly reduced by one structural intervention. All three types of interventions improved condom use among AGYW. Evidence suggests that structural interventions can reduce HIV incidence, while behavioral and combined interventions require further investigation.

Abstract
title: Effects of fluid composition on the precipitation behaviour and shape of minerals
Creators: name:  Stipp ,  Susan
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2021

description: Minerals form by the ordered arrangement of atoms. Each mineral has a characteristic form, determined by the electron configuration of the atoms of its structure and the temperature and pressure of the system. However in nature, where no system is pure, mineral structure is also affected by other atoms in the fluid, be it deposition from a melt, an aqueous solution or a vapour. Minor and even trace concentrations of foreign species can completely change crystal form. Organisms take advantage of this. During their millions of years of evolution, they have developed biomolecules that enhance or inhibit growth on certain crystal sites so they can control mineral growth to precisely equip them for their ecological niche. Whether the trace components are inorganic or organic, the change in mineral form can be dramatic. From an ideal laboratory solution for example, green rust, a layered Fe(II), Fe(III) double hydroxide, precipitates as broad, flat, hexagonal plates. Aluminium, which also forms hydroxide minerals, can substitute for Fe(III) but its smaller ionic radius causes distortion in the green rust structure and crystal radius decreases. Organic impurities can have a dramatic effect, exemplified by biominerals, where bones, teeth and shells look and function quite differently than inorganically formed hydroxyapatite, calcite and aragonite. Polysaccharides, even at parts per million concentration, transform the typical rhombohedral shape of calcite into beautiful, intricate discs, that the coccolithophore algae use to cover their single cell. Learning nature’s tricks for controlling crystal growth provides us with clues for developing new, functional materials.

description: We report \textit{ab initio} no-core shell model (NCSM) study of $^{18-24}$Ne isotopes for energy spectra, electromagnetic properties, and point-proton radii using three realistic $NN$ interactions. We have used inside nonlocal outside Yukawa (INOY), charge-dependent Bonn 2000 (CDB2K) and the chiral next-to-next-to-next-to-leading order (N$^3$LO) interactions. We are able to reach basis size up to $N_{max}$ = 6 for $^{18}$Ne and $N_{max}$ = 4 for the $^{19-24}$Ne isotopes with m-scheme dimensions up to 1.0 $\times$ $10^9$ in case of $^{24}$Ne. We observed better results for INOY interaction in terms of the binding energies of ground state (g.s.), and overall all three interactions provide good agreement with the experimental low-energy spectra. Our results for reduced $M1$ transition strengths and magnetic moments are close to the experimental values. We found that for long-range observables such as the $E2$ transition strengths, the electric quadrupole moments, and the point-proton radii ($r_p$), we need higher $N_{max}$ calculations to obtain results comparable to the experimental data. We have observed almost 6 \% increment in the converged $r_p$ as we increase the model space from $N_{max}$ = 4 to $N_{max}$ = 6.

description: This study proposes a novel Modified Bond-Based PeriDynamic (MBB-PD) model based on the bonds' classification. This classification of bonds is performed on the basis of the equivalent hypothetical local strains and falls into three categories of horizontal normal, vertical normal, and shear bonds. While the classical Bond-Based PD (BB-PD) considers only the stretch of bonds, all components of the bonds' strains are taken into account in the proposed model.A local imaginary element is considered around each bond to estimate the true strains of each bond. The constitutive relations are derived from equating the strain energies of the bonds' deformations to the Classical Continuum Mechanics (CCM) strain energies for a generalized combined loading condition. A novel critical stretch criterion and critical angle criterion are proposed to predict the failure of normal and shear strain bonds, respectively.It is also shown that, unlike the classical BB-PD, the proposed model does not impose any limitations on the value of Poisson's ratio. The model is verified by investigating some intact plane stress and plane strain problems under mechanical and thermal loadings. Moreover, the deformation and damage contours and the corresponding stress-strain responses are presented for different problems with pre-existing defects and validated with the eXtended Finite Element method's (XFEM) analysis.

description: Although cash transfers (CT) are hypothesized to reduce AGYW’s HIV risk, little is known about the mechanisms through which CT empower AGYW. We explored the impact of a CT intervention on AGYW’s sexual decision-making in order to describe the pathways through which the cash may influence risk behavior. The study employed qualitative methods involving: 20 longitudinal in-depth interviews (IDIs), 40 cross-sectional IDIs, 20 narrative IDIs, and two focus group discussions with AGYW ages 15–23 participating in a CT intervention. AGYW’s conceptualized empowerment as: “independence”, “hope and aspiration”. Potential pathways through which CT empowered AGYW were: economic, hope and aspiration for a better future, and access to knowledge. As a result of this empowerment, AGYW reported reductions in transactional sex, experiences of intimate partner violence, and risky-sexual behaviour. A sense of responsibility developed through economic empowerment, enhanced participants’ self-esteem and confidence in decision-making leading to changes in AGYW’s sexual risk behaviors.

description: It has been clear for past many years that in low energy observables new physics can only appear as a perturbation. Therefore precise theoretical predictions and precise experimental measurements have become mandatory. Here we draw attention to the significant advances that have been made on the lattice in recent years in $K\to ππ$, $ΔM_K$, the long-distance part of $\varepsilon$ and rare K-decays. Thus, in conjunction with experiments, the construction of a unitarity triangle purely from Kaon physics should soon become feasible. Along with the B-unitarity triangle, this should allow for more stringent tests of the Standard Model and tighter constraints on new physics.

description: PEPSI is the bench-mounted, two-arm, fibre-fed and stabilized Potsdam Echelle Polarimetric and Spectroscopic Instrument for the 2x8.4 m Large Binocular Telescope (LBT). Three spectral resolutions of either 43 000, 120 000 or 270 000 can cover the entire optical/red wavelength range from 383 to 907 nm in three exposures. Two 10.3kx10.3k CCDs with 9-μm pixels and peak quantum efficiencies of 96 % record a total of 92 echelle orders. We introduce a new variant of a wave-guide image slicer with 3, 5, and 7 slices and peak efficiencies between 96 %. A total of six cross dispersers cover the six wavelength settings of the spectrograph, two of them always simultaneously. These are made of a VPH-grating sandwiched by two prisms. The peak efficiency of the system, including the telescope, is 15% at 650 nm, and still 11% and 10% at 390 nm and 900 nm, respectively. In combination with the 110 m2 light-collecting capability of the LBT, we expect a limiting magnitude of 20th mag in V in the low-resolution mode. The R=120 000 mode can also be used with two, dual-beam Stokes IQUV polarimeters. The 270 000-mode is made possible with the 7-slice image slicer and a 100- μm fibre through a projected sky aperture of 0.74", comparable to the median seeing of the LBT site. The 43000-mode with 12-pixel sampling per resolution element is our bad seeing or faint-object mode. Any of the three resolution modes can either be used with sky fibers for simultaneous sky exposures or with light from a stabilized Fabry-Perot etalon for ultra-precise radial velocities. CCD-image processing is performed with the dedicated data-reduction and analysis package PEPSI-S4S. A solar feed makes use of PEPSI during day time and a 500-m feed from the 1.8 m VATT can be used when the LBT is busy otherwise. In this paper, we present the basic instrument design, its realization, and its characteristics.

description: The temperature dependence of electric transport properties of single-layer and few-layer graphene at large charge doping is of great interest both for the study of the scattering processes dominating the conductivity at different temperatures and in view of the theoretically predicted possibility to reach the superconducting state in such extreme conditions. Here we present the results obtained in 3-, 4- and 5-layer graphene devices down to 3.5 K, where a large surface charge density up to about 6.8x10^14 cm^(-2) has been reached by employing a novel polymer electrolyte solution for the electrochemical gating. In contrast with recent results obtained in single-layer graphene, the temperature dependence of the sheet resistance between 20 K and 280 K shows a low-temperature dominance of a T^2 component - that can be associated with electron-electron scattering - and, at about 100 K, a crossover to the classic electron-phonon regime. Unexpectedly this crossover does not show any dependence on the induced charge density, i.e. on the large tuning of the Fermi energy.

description: In recent years, several trends are indicating a move towards a very different bulk power system. Increased integration of renewables, energy storage, synchrophasors, microgrids, Internet of Things devices, and electric vehicles are increasing the complexity of the system. While these changes have the potential to lead to significant reductions in environmental impact and peak demand growth, they also require significantly stronger, granular, and faster-moving controls to ensure reliability and resiliency. Previous research shows that electric vehicles have the potential to significantly reduce global (e.g., CO2), and regional (e.g., particulate) emissions associated with transportation. As fast-responding flexible loads, it was hypothesized that electric vehicles could participate in reliability-centric markets. To study the integration of these vehicles into the bulk power system, this project involved building an experimental charging system for electric vehicles with bulk modeling of the electric grid. This research test bed was developed in Taylor, Texas, to analyze real-world behavior of EVs in response to control signals. The diverse group of participating vehicles provided rapid response between 1/6 and 1/2 second, suggesting a strong capacity for providing grid reliability services. Successful real-world tests of primary frequency response and dispatched load control highlight the scalability of this approach. Vehicle charging patterns (as measured by load ramp and current waveform at peak) were observed to be clustered by vehicle make, indicating predictive value of high-resolution waveform measurement at the beginning of a charging session. Simulation of a network with intermittent renewables shows that inclusion of these rapidly responding EVs can strengthen system stability in normal, black start, and islanded situations. It shows that controlled EV charging can provide reliable means for improved renewables integration. The aggregation of electric vehicle charging can certainly provide fast-responding services that provide frequency support, congestion management, synthetic inertia, and many other useful services of significant value to the reliability of the bulk power system

description: The biochemical aspects of adaptation to brackish water (30 p. 100 sea water) have been studied in two species of euryhaline shrimps : Leander squilla L. and Leander serratus F. A first mechanism, consisting of an anisosmotic regulation of the blood, has been described by Pannikar in these organisms. A variation of osmotic pressure in the external medium, amounting to 1.7°C, brings about a change of only 0.°3C and 0.°6C respectively, in the blood of the two species considered. As shown by the slight change of water content of the muscles, the intracellular osmotic pressure has been approximately adjusted, in these shrimps, to the osmotic pressure of the blood. This isosmotic, intracellular regulation is accomplished for about 1/3 by the variation of concentration of a number of intracellular free amino-acids. The main rôle is played by glutamine, glycine and proline in both species. In L. serratus alanine also shows important variations. The mechanism of intracellular osmoregulation by changes of concentration of the amino-acids mentioned, has been observed in all euryhaline Invertebrates studied so far. It appears as a general device of adaptation to changes of concentration of the internal medium, in euryhaline forms.

description: Physico-chemical continuum battery models are typically parameterized by manual fits, relying on the individual expertise of researchers. In this article, we introduce a computer algorithm that directly utilizes the experience of battery researchers to extract information from experimental data reproducibly. We extend Bayesian Optimization (BOLFI) with Expectation Propagation (EP) to create a black-box optimizer suited for modular continuum battery models. Standard approaches compare the experimental data in its raw entirety to the model simulations. By dividing the data into physics-based features, our data-driven approach uses orders of magnitude less simulations. For validation, we process full-cell GITT measurements to characterize the diffusivities of both electrodes non-destructively. Our algorithm enables experimentators and theoreticians to investigate, verify, and record their insights. We intend this algorithm to be a tool for the accessible evaluation of experimental databases.

description: We compute the one-instanton effective action of N=4 super Yang-Mills theory with gauge group Sp(2N). The result can be written in a very compact and manifestly supersymmetric form involving an integral over the superspace of an irrational function of the N=4 on-shell superfields. In the Coulomb branch, the instanton corrects both the MHV and next-to-next-MHV higher derivative terms D^4F^{2n+2} and F^{2n+4}. We confirm at the non-perturbative level the non-renormalization theorems for MHV F^{2n+2} terms that are expected to receive perturbative corrections only at n-loops. We compute also the one and two-loop corrections to the D^4F^4 term and show that its completion under SL(2,Z) duality is consistent with the one-instanton results of U(2) gauge group.

We estimated the longitudinal effects of alcohol use on IPV perpetration among MWH. Methods: This study is a secondary analysis of randomized controlled trial data among male and female antiretroviral treatment patients with hazardous alcohol use in Thai Nguyen, Vietnam. Analyses were restricted to male participants who were married/cohabitating (N = 313). Alcohol use was assessed as proportion days alcohol abstinent, heavy drinking, and alcohol use disorder (AUD) using the Timeline Followback and Mini International Neuropsychiatric Interview questionnaire. Multilevel modeling was used to estimate the effects of higher versus lower average alcohol use on IPV perpetration (between-person effects) and the effects of time-specific deviations in alcohol use on IPV perpetration (within-person effects). Results: Participants with higher average proportion days alcohol abstinent had decreased odds of IPV perpetration (adjusted Odds Ratio [aOR] = 0.43, p = 0.03) and those with higher average heavy drinking and AUD had increased odds of IPV perpetration (Heavy drinking: aOR = 1.05, p = 0.002; AUD: aOR = 4.74, p < 0.0001). Time-specific increases in proportion days alcohol abstinent were associated with decreased odds of IPV perpetration (aOR = 0.39, p = 0.02) and time-specific increases in AUD were associated with increased odds of IPV perpetration (aOR = 2.95, p = 0.001). Within-person effects for heavy drinking were non-significant. Conclusions: Alcohol use is associated with IPV perpetration among Vietnamese men with HIV. In this context, AUD and frequent drinking are stronger correlates of IPV perpetration as compared to heavy drinking.

description: 1. The tissues of the crab Carcinus maenas were analysed for their copper content. The values we obtained were carapace, 9.6; gill 38.5; foregut 10.0; intestine 6.9 ; muscle 9.6; heart, less than 3; blood 15-150; hepatopancreas 20-125;
the values being in ¿¿g copper/g. wet weight of tissue.
2. Throughout bi-monthly analyses of both the blood and hepatopancreas of the crab over two years, the blood had a higher copper content than the hepatopancreas.
3. There is a yearly variation in the blood copper content, with a minimum atthe time of ecdysis. The fall in copper content before ecdysis being gradual.
4. There is no indication of the transfer of copper from the hepatopancreasto the blood after ecdysis. Instead the increase in copper in both tissues is interpreted as an active uptake of copper by the animal from the environment.
5. The copper in the blood was not considered to be in an ionic state since it was not in free equilibrium with a dialysate.
6. Animals placed in copper rich solutions, accumulated copper in the hepatopancreas, not the blood.

description: This thesis discusses a mixed-methods case study exploring newly qualified nurses’ (NQNs) educational preparation for autonomous professional practice and factors influencing the transition process. The ontological perspective is pragmatism advocating that the research question itself is central to the study influencing methods employed. It draws on concepts of professional learning and competence (Eraut, 1994: 2004), situated learning theory (Lave and Wenger, 1991, Wenger, 1998) and workplace learning (Illeris, 2011). Engeström’s (2001) Cultural Historical Activity Theory (CHAT) framework is used as a theoretical lens to explore the NQNs’ two main activity systems: a higher education nursing programme and first-post employment as an NQN. The framework aids identification of disturbances in the systems. Methods of data collection included an online survey of 63 participants, 3 focus groups and individual interviews with 15 participants from across all fields of preregistration nursing: Adult, Children’s; Learning Disabilities and Mental Health. Findings suggest transition from student nurse to NQN is exciting but stressful. In preparation to be an NQN, graduate skills such as evidence-based practice and reflection skills were recognised as beneficial and transferable for problem-solving new situations. Main sources of anxiety included: the reality of being professionally accountable for their practice; fear of making mistakes; delivering complex care; missing signs of patient deterioration; and loss of confidence in their own competence and clinical decision-making. There was lack of equity in provision or type of preceptorship with some NQNs feeling unsupported. Supportive preceptorships and gaining confidence were key factors in successful transition gained by experience of significant events and advocating for patients. Confident clinical decision-making requires tacit knowledge and experience so simulation of complex case-based learning with advanced clinical decision-making with final-year nurses is suggested. Final year placements allowing supervised practice of complex communication and care delivery supported by experienced mentors fostering learning is advocated. National standards for preceptorship need to be developed and made mandatory with guidance on content and preceptor training to include pastoral support as well as technical skills training. Universities and their local placement providers as potential employers could work more collaboratively to understand students’ previous learning and how that could be built upon in joint planning for transition.

description: In the present paper, we consider the Cauchy problem of fourth order nonlinear Schrödinger type equations with a derivative nonlinearity. In one dimensional case, we prove that the fourth order nonlinear Schrödinger equation with the derivative quartic nonlinearity $\partial _x (\overline{u}^4)$ is the small data global in time well-posed and scattering to a free solution. Furthermore, we show that the same result holds for the $d \ge 2$ and derivative polynomial type nonlinearity, for example $|\nabla | (u^m)$ with $(m-1)d \ge 4$.

description: The large available Hilbert space and high coherence of cavity resonators makes these systems an interesting resource for storing encoded quantum bits. To perform a quantum gate on this encoded information, however, complex nonlinear operations must be applied to the many levels of the oscillator simultaneously. In this work, we introduce the Selective Number-dependent Arbitrary Phase (SNAP) gate, which imparts a different phase to each Fock state component using an off-resonantly coupled qubit. We show that the SNAP gate allows control over the quantum phases by correcting the unwanted phase evolution due to the Kerr effect. Furthermore, by combining the SNAP gate with oscillator displacements, we create a one-photon Fock state with high fidelity. Using just these two controls, one can construct arbitrary unitary operations, offering a scalable route to performing logical manipulations on oscillator-encoded qubits.

description: We present an exact solution in arbitrary dimensions for the steady states of a class of quantum driven-dissipative bosonic models, where a set of modes is subject to arbitrary two-photon driving, single-photon loss and a global Hubbard (or Kerr)-like interaction. Our solutions reveal a wealth of striking phenomena, including the emergence of dissipative phase transitions, nontrivial mode competition physics and symmetry breaking, and the stabilization of many-body $SU(1,1)$ pair coherent states. Our exact solutions enable the description of spatial correlations, and are fully valid in regimes where traditional mean-field and semiclassical approaches break down.

description: Despite the growing popularity of multidimensional poverty measurement and analysis, its use to measure the impact of social protection programs remains scarce. Using primary data collected for the evaluation of HIV Prevention Trials Network (HPTN) 068, a randomized, conditional cash transfer intervention for young girls in South Africa that ran from 2011 to 2015, we construct an individual-level measure of multidimensional poverty, a major departure from standard indices that use the household as the unit of analysis. We construct our measure by aggregating multiple deprivation indicators across six dimensions and using a system of nested weights where each domain is weighted equally. Our findings show that the cash transfer consistently reduces deprivations among girls, in particular through the domains of economic agency, violence, and relationships. These results show how social protection interventions can improve the lives of young women beyond single domains and demonstrate the potential for social protection to simultaneously address multiple targets of the SDGs.

description: We compute the imaginary parts of genus-one string scattering amplitudes. Following Witten's $i\varepsilon$ prescription for the integration contour on the moduli space of worldsheets, we give a general algorithm for computing unitarity cuts of the annulus, Möbius strip, and torus topologies exactly in $α'$. With the help of tropical analysis, we show how the intricate pattern of thresholds (normal and anomalous) opening up arises from the worldsheet computation. The result is a manifestly-convergent representation of the imaginary parts of amplitudes, which has the analytic form expected from Cutkosky rules in field theory, but bypasses the need for performing laborious sums over the intermediate states. We use this representation to study various physical aspects of string amplitudes, including their behavior in the $(s,t)$ plane, exponential suppression, decay widths of massive strings, total cross section, and low-energy expansions. We find that planar annulus amplitudes exhibit a version of low-spin dominance: at any finite energy, only a finite number of low partial-wave spins give an appreciable contribution to the imaginary part.
