description: We study the superstring theory on pp-wave background with NSNS-flux that is realized as the Penrose limit of AdS_3 x S^3 x M^4, where M^4 is T^4 or T^4/Z_2(~ K3). Quantizing this system in the covariant gauge, we explicitly construct the space-time supersymmetry algebra and the complete set of DDF operators. We analyse the spectrum of physical states by using the spectrally flowed representations of current algebra. This spectrum is classified by the ``short string sectors'' and the ``long string sectors'' as in AdS_3 string theory. The states of the latter propagate freely along the transverse plane of pp-wave background, but the states of the former do not. We compare the short string spectrum with the BPS and almost BPS states which have large R-charges in the symmetric orbifold conformal theory, which is known as the candidate of dual theory of superstrings on AdS_3 x S^3 x M^4. We show that every short string states can be embedded successfully in the single particle Hilbert space of symmetric orbifold conformal theory.

description:
Among intrauterine infections, Cytomegalovirus (CMV) is one of those that occurs most frequently, being found as a primary infection, according to the most recent statistics, in a percentage varying from 1% to 4% of pregnant women. In primary CMV infections, the possibility of fetal transmission of the infection is around 30-40%, values which can increase up to 70% if the mother contracts the infection in the third trimester of pregnancy. CMV infection is the most common cause of congenital hearing loss, from non- genetic causes, even if hearing loss is not always evident at birth, as it can be detected later. Congenital CMV infection is generally responsible for a total of 30% of cases of deafness of unknown cause and 43% of those with severe or profound loss. It is estimated that 2% of children with asymptomatic congenital CMV develop hearing loss severe enough to meet the criteria for cochlear implant candidacy.

description: The research field of magnetic frustration is dominated by triangle-based lattices but exotic phenomena can also be observed in pentagonal networks. A peculiar noncollinear magnetic order is indeed known to be stabilized in Bi2Fe4O9 materializing a Cairo pentagonal lattice. We present the spin wave excitations in the magnetically ordered state, obtained by inelastic neutron scattering. They reveal an unconventional excited state related to local precession of pairs of spins. The magnetic excitations are then modeled to determine the superexchange interactions for which the frustration is indeed at the origin of the spin arrangement. This analysis unveils a hierarchy in the interactions, leading to a paramagnetic state (close to the Néel temperature) constituted of strongly coupled dimers separated by much less correlated spins. This produces two types of response to an applied magnetic field associated with the two nonequivalent Fe sites, as observed in the magnetization distributions obtained using polarized neutrons.

description: Knowing the error distribution is important in many multivariate time series applications. To alleviate the risk of error distribution mis-specification, testing methodologies are needed to detect whether the chosen error distribution is correct. However, the majority of existing tests only deal with the multivariate normal distribution for some special multivariate time series models, and thus cannot be used for testing the often observed heavy-tailed and skewed error distributions in applications. In this article, we construct a new consistent test for general multivariate time series models, based on the kernelized Stein discrepancy. To account for the estimation uncertainty and unobserved initial values, a bootstrap method is provided to calculate the critical values. Our new test is easy-to-implement for a large scope of multivariate error distributions, and its importance is illustrated by simulated and real data. As an extension, we also show how to test for the error distribution in copula time series models.

description: The emission rate of photons from a hot, weakly coupled ultrarelativistic plasma is analyzed. Leading-log results, reflecting the sensitivity of the emission rate to scattering events with momentum transfers from $gT$ to $T$, have previously been obtained. But a complete leading-order treatment requires including collinearly enhanced, inelastic processes such as bremsstrahlung. These inelastic processes receive O(1) modifications from multiple scattering during the photon emission process, which limits the coherence length of the emitted radiation (the Landau-Pomeranchuk-Migdal effect). We perform a diagrammatic analysis to identify, and sum, all leading-order contributions. We find that the leading-order photon emission rate is not sensitive to non-perturbative $g^2 T$ scale dynamics. We derive an integral equation for the photon emission rate which is very similar to the result of Migdal in his original discussion of the LPM effect. The accurate solution of this integral equation for specific theories of interest will be reported in a companion paper.

description: Bush fires raged across the Brazilian Amazon in 2019. The CO2 that was sequestered in those forests is now in the atmosphere, adding to the rate of global warming. The burned-over land will likely be converted to agriculture. Possible contributors to these events include climate change itself, creating hotter, drier conditions, and what is reportedly a reduction in the vigor of forest preservation efforts under a new government. But here we explore a third possible contributor: technical change may have been increasing the incentives to convert forests to agriculture. We examine the nature of technical change from 2003 to 2015, across 287 municipalities within Brazil’s “arc of deforestation”. We consider grains, livestock and timber as agricultural outputs and CO2 emission from deforestation as an undesirable output. On average across the region, we estimate the annual rate of technical change in agriculture over this period to have been 4.9%, with a significant bias toward agricultural outputs and away from CO2 emissions, meaning that it has been increasingly attractive to convert these forests to agriculture. This technological incentive for deforestation has thus been building up during the early part of this century, but actual deforestation was held in check somewhat by forest preservation policies until recently, when a more relaxed policy environment has allowed the increased technological incentive for deforestation to be more fully expressed. These changes have added to climate change as contributors to the recent burst in Amazon forest destruction.

Introduction - Congenital Cytomegalovirus (cCMV) infection is the main cause of non-hereditary sensorineural hearing loss in children. The Emilia Romagna region has been adopting the newborn hearing screening (NHS) program since 2012. It is based on a two-stage protocol, which is different for healthy babies and the ones admitted to the neonatal intensive care unit. All the children who failed the NHS have undergone urine CMV analysis within the following 14 days since 2013. The present study evaluated the outcomes of the audiological follow up in newborns affected by cCMV infection since the protocol was adopted in Modena University Hospital. Materials and methods - This is a retrospective longitudinal study. Data collected include gestational age, weight at birth, results of NHS test, entity and type of hearing loss, possible use of antiviral therapy, length of audiological follow up, outcomes of treatment. All neonates born between 2013 and 2023 at Modena University hospital were enrolled in the study. Results - During a period of ten years, 32.103 newborns were delivered and 99.4% of them underwent NHS. 38 children were identified as affected by cCMV, 33 of them (86%) had a “pass” result, 4 had a bilaterally “fail” result, 1 a unilateral “fail”. In 7 cases (18%) a diagnosis of hearing loss was made. 1 case (14%) was diagnosed through the NHS test. In 13/36 cases (36%) , excluding those born in 2023, audiological follow up was interrupted at the age of 12 months. Conclusions - This study demonstrated that coupling the cCMV screening and the NHS program is useful for diagnostic purposes as it allows early recognition of asymptomatic cases of hearing loss. The protocol adopted proved to be effective. However, the study evidenced that families of newborns showed lack of compliance and failed in completing an audiological follow up over 12 months.

description: Natal kicks are matter of debate and significantly affect the merger rate density of compact objects. Here, we present a new simple formalism for natal kicks of neutron stars (NSs) and black holes (BHs). We describe the magnitude of the kick as $v_{\rm kick}\propto{}f_{\rm H05}\,{}\,{}m_{\rm ej}\,{}\,{}m_{\rm rem}^{-1}$, where $f_{\rm H05}$ is a normalization factor, drawn from a Maxwellian distribution with one-dimensional root-mean-square velocity $σ=265$~km~s$^{-1}$, $m_{\rm ej}$ is the mass of the supernova (SN) ejecta and $m_{\rm rem}$ is the mass of the compact object. This formalism matches the proper motions of young Galactic pulsars and can naturally account for the differences between core-collapse SNe of single stars, electron-capture SNe and ultra-stripped SNe occurring in interacting binaries. Finally, we use our new kick formalism to estimate the local merger rate density of binary NSs ($R_{\rm BNS}$), BH--NS binaries ($R_{\rm BHNS}$) and binary BHs ($R_{\rm BBH}$), based on the cosmic star formation rate density and metallicity evolution. In our fiducial model, we find $R_{\rm BNS}\sim{}600$~Gpc$^{-3}$~yr$^{-1}$, $R_{\rm BHNS}\sim{}10$~Gpc$^{-3}$~yr$^{-1}$ and $R_{\rm BBH}\sim{}50$~Gpc$^{-3}$~yr$^{-1}$, fairly consistent with the numbers inferred from the LIGO-Virgo collaboration.

INTRODUCTION - Congenital CMV infection is the main cause of late sensorineural hearing loss and neurological disorders. It is often asymptomatic at birth and remains latent over time. OBJECTIVE OF THE STUDY - The aim of this study is to make a comparison between universal screening and expandedtargeted screening that took place at different times at our hospital. MATERIALS AND METHODS - Universal screening at birth was applied from October 2015 to May 2017. All newborns at the Spedali Civili ( from newborn and intensive care unit) underwent saliva testing for CMV . From 2021 to 2023,expandedtargeted screening was applied to newborns, so only infants with symptoms related to infection or refer at otohaemissions (TEOAE) were analized. In both cases a positive saliva test was confirmed by plasma or urine test. The positive patients underwent audiological follow-up and auxological, ophthalmological and neuropsychiatric check-ups. RESULTS - All 5032 infants were tested in the first period (2015-2017). The CMV test was positive in 21 infants (0.41%), 2 refer and 19 pass. In the second period (2021-2023), on the other hand, 9792 infants were born, of whom 130 were born to a mother with CMV infection or with symptoms suggestive of infection and were therefore tested. Of these, 17 (0.17%) were positive for infection, 7 were refer and 10 pass. CONCLUSIONS- The universal test is more complete than the targeted test in identifying patients who have a silent congenital infection and allows them to be monitored over time to detect late sequelae at an early stage. It could be applied thanks to the accessibility of the saliva test.

description: We investigate the impact of stellar rotation on the formation of black holes (BHs), by means of our population-synthesis code SEVN. Rotation affects the mass function of BHs in several ways. In massive metal-poor stars, fast rotation reduces the minimum zero-age main sequence (ZAMS) mass for a star to undergo pair instability and pulsational pair instability. Moreover, stellar winds are enhanced by rotation, peeling-off the entire hydrogen envelope. As a consequence of these two effects, the maximum BH mass we expect from the collapse a rotating metal-poor star is only $\sim{}45$ M$_\odot$, while the maximum mass of a BH born from a non-rotating star is $\sim{}60$ M$_\odot$. Furthermore, stellar rotation reduces the minimum ZAMS mass for a star to collapse into a BH from $\sim{}18-25$ M$_\odot$ to $\sim{}13-18$ M$_\odot$. Finally, we have investigated the impact of different core-collapse supernova (CCSN) prescriptions on our results. While the threshold value of compactness for direct collapse and the fallback efficiency strongly affect the minimum ZAMS mass for a star to collapse into a BH, the fraction of hydrogen envelope that can be accreted onto the final BH is the most important ingredient to determine the maximum BH mass. Our results confirm that the interplay between stellar rotation, CCSNe and pair instability plays a major role in shaping the BH mass spectrum.

Comparing this to the binding energies of different quarkonium states, we check if these can decay into open charm/beauty in a confined hadronic medium. Our studies indicate in particular that the chi_c and the psi dissociate into open charm below the deconfinement point.

description: Abstract: High-rate lithium ion batteries with long cycling lives can provide electricity grid stabilization services in the presence of large fractions of intermittent generators, such as photovoltaics. Engineering for high rate and long cycle life requires an appropriate selection of materials for both electrode and electrolyte and an understanding of how these materials degrade with use. High-rate lithium ion batteries can also facilitate faster charging of electric vehicles and provide higher energy density alternatives to supercapacitors in mass transport applications. High-rate lithium ion batteries can play a critical role in decarbonizing our energy systems both through their underpinning of the transition to use renewable energy resources, such as photovoltaics, and electrification of transport. Their ability to be rapidly and frequently charged and discharged can enable this energy storage technology to play a key role in stabilizing future low-carbon electricity networks which integrate large fractions of intermittent renewable energy generators. This decarbonizing transition will require lithium ion technology to provide increased power and longer cycle lives at reduced cost. Rate performance and cycle life are ultimately limited by the materials used and the kinetics associated with the charge transfer reactions and ionic and electronic conduction. We review material strategies for electrode materials and electrolytes that can facilitate high rates and long cycle lives and discuss the important issues of cost, resource availability and recycling.
An expected value of sample information (EVSI) approach for estimating the payoff from a variable rate technology.

description: This paper examines the payoff to variable rate technology (VRT) using a Bayesian approach following literature on the expected value of sample information (EVSI). In each cell within a field, we compare the expected payoff from an optimal variable rate conditioned on a signal from that cell, with the expected payoff from a uniform rate technology (URT) that is optimal for all cells in the field. This comparison, when evaluated across the theoretical distribution of signals, provides an estimate of the expected gross benefit from VRT relative to URT. Under plausible assumptions, a closed-form algebraic solution relates this expected benefit to field and nitrogen response characteristics. We apply our approach to data from on-farm field-level experiments conducted by the Data-Intensive Farm Management Project (DIFM) (Bullock, et al. 2019), which examined nitrogen (N) response across cells for which soil electroconductivity (EC) served as the signal related to nitrogen response. We calculate the expected gross benefits to be about $1.81/ac, insufficient to support costs of VRT implementation. Our model provides quantitative estimates of the extent to which this poor outcome could be improved by a higher correlation between the EC signal and the state of nature of interest, by higher variability of the state of nature across cells, and by a sharper curvature of yield response to N.

description: Berry curvature is an imaginary component of the quantum geometric tensor (QGT) and is well studied in many branches of modern physics; however, the quantum metric as a real component of the QGT is less explored. Here, by using tunable superconducting circuits, we experimentally demonstrate two methods to directly measure the quantum metric tensor for characterizing the geometry and topology of underlying quantum states in parameter space. The first method is to probe the transition probability after a sudden quench, and the second one is to detect the excitation rate under weak periodic driving. Furthermore, based on quantum-metric and Berry-curvature measurements, we explore a topological phase transition in a simulated time-reversal-symmetric system, which is characterized by the Euler characteristic number instead of the Chern number. The work opens up a unique approach to explore the topology of quantum states with the QGT.

description: Inflation ends with the formation of a Bose condensate of inflatons. We show that in hybrid inflation models this condensate is typically unstable with respect to spatial perturbations and can fragment to condensate lumps. The case of D-term inflation is considered as an example and it is shown that fragmentation occurs if λ> 0.2g, where λis the superpotential coupling and g is the U(1)_{FI} gauge coupling. Condensate fragmentation can result in an effective enhancement of inflaton annihilations over decays as the main mode of reheating. In the case of D-term inflation models in which the Standard Model fields carry U(1)_{FI} charges, if condensate fragmentation occurs then reheating is dominated by inflaton annihilations, typically resulting in the overproduction of thermal gravitinos. Fragmentation may also have important consequences for SUSY flat direction dynamics and for preheating.

description: Web 2.0 applications like Twitter or Facebook create a continuous stream of information. This demands new ways of analysis in order to offer insight into this stream right at the moment of the creation of the information, because lots of this data is only relevant within a short period of time. To address this problem real time search engines have recently received increased attention. They take into account the continuous flow of information differently than traditional web search by incorporating temporal and social features, that describe the context of the information during its creation. Standard approaches where data first get stored and then is processed from a peristent storage suffer from latency. We want to address the fluent and rapid nature of text stream by providing an event based approach that analyses directly the stream of information. In a first step we want to define the difference between real time search and traditional search to clarify the demands in modern text filtering. In a second step we want to show how event based features can be used to support the tasks of real time search engines. Using the example of Twitter we present in this paper a way how to combine an event based approach with text mining and information filtering concepts in order to classify incoming information based on stream features. We calculate stream dependant features and feed them into a neural network in order to classify the text streams. We show the separative capabilities of event based features as the foundation for a real time search engine.

description: Integrability in string/field theories is known to emerge when considering dynamics in the moduli space of physical theories. This implies that one has to look at the dynamics with respect to unusual time variables like coupling constants or other quantities parameterizing configuration space of physical theories. The dynamics given by variations of coupling constants can be considered as a canonical transformation or, infinitesimally, a Hamiltonian flow in the space of physical systems. We briefly consider here an example of mechanical integrable systems. Then, any function $T(\vec p, \vec q)$ generates a one-parametric family of integrable systems in vicinity of a single system. For integrable system with several coupling constants the corresponding "Hamiltonians" $T_i(\vec p, \vec q)$ satisfy Whitham equations and after quantization (of the original system) become operators satisfying the zero-curvature condition in the space of coupling constants: $$ [\frac{\partial}{\partial g_a} - \hat T_a(\hat{\vec p},\hat{\vec q}),\ \frac{\partial}{\partial g_b} - \hat T_b(\hat{\vec p},\hat{\vec q})] = 0 $$

description: Abstract: Background: Despite the importance of the mucosal interface between microbiota and the host in gut homeostasis, little is known about the mechanisms of bacterial gut colonization, involving foraging for glycans produced by epithelial cells. The slow pace of progress toward understanding the underlying molecular mechanisms is largely due to the lack of efficient discovery tools, especially those targeting the uncultured fraction of the microbiota. Results: Here, we introduce an ultra-high-throughput metagenomic approach based on droplet microfluidics, to screen fosmid libraries. Thousands of bacterial genomes can be covered in 1 h of work, with less than ten micrograms of substrate. Applied to the screening of the mucosal microbiota for β-N-acetylgalactosaminidase activity, this approach allowed the identification of pathways involved in the degradation of human gangliosides and milk oligosaccharides, the structural homologs of intestinal mucin glycans. These pathways, whose prevalence is associated with inflammatory bowel diseases, could be the result of horizontal gene transfers with Bacteroides species. Such pathways represent novel targets to study the microbiota-host interactions in the context of inflammatory bowel diseases, in which the integrity of the mucosal barrier is impaired. Conclusion: By compartmentalizing experiments inside microfluidic droplets, this method speeds up and miniaturizes by several orders of magnitude the screening process compared to conventional approaches, to capture entire metabolic pathways from metagenomic libraries. The method is compatible with all types of (meta)genomic libraries, and employs a commercially available flow cytometer instead of a custom-made sorting system to detect intracellular or extracellular enzyme activities. This versatile and generic workflow will accelerate experimental exploration campaigns in functional metagenomics and holobiomics studies, to further decipher host-microbiota relationships.

treatment of cCMV-induced hearing loss

description:
Congenital cytomegalovirus infection is one of the main causes of sensorineural hearing loss and delayed neurological development in children. The incidence of hearing loss ranges from 7-21%, with variable and often late onset. Since 2012, the year in which universal neonatal hearing screening became mandatory in Italy, the cohort of newborns under follow-up in our Service has been systematically organized. The cohort of children under follow-up for cCMV includes 143 patients. This paper reports on the audiological follow-up data and therapeutic aspects.

Objectives: The aim of the present study aims is to describe a sample of patients with congenital cytomegalovirus (cCMV) infection, particularly focusing on audiological and neurological/neuroradiological data. Methods: Retrospective study on a sample of 25 subjects with cCMV infection (symptomatic and asymptomatic), followed at the Audiology Service of the Sant’ Anna Hospital (Ferrara). The following data were collected: maternal CMV infection (primary versus non-primary), time of in-utero infection, systemic signs and/or symptoms or laboratory tests anomalies due to cCMV infection, and signs and/ or symptoms of central nervous system involvement at birth. In addition, a brain imaging analysis was performed among symptomatic patients, evaluating the available brain ultrasonography and encephalic Magnetic Resonance Imaging (MRI) exams. Results: 14 patients presented asymptomatic cCMV infection, while 11 symptomatic infection. 18/25 (72%) patients developed sensorineural hearing loss (SNHL) - 8 patients in the asymptomatic group and 10 patients in the symptomatic one. 3 cases of late-onset SNHL were identified in asymptomatic patients. 6/11 subjects with symptomatic infection showed neurological signs and/or symptoms at birth. Ventriculomegaly, cystic/psuedocystic lesions, white matter abnormalities, and lenticulostriate vasculopathy were the most frequent neuroradiologic anomalies found among symptomatic patients. Conclusions: SNHL occurred more frequently in the symptomatic group. Asymptomatic patients remain at risk to develop SNHL, too. Therefore, the referral to Audiology Center of all newborns with a diagnosis of cCMV infection at birth should be recommended. More than half of symptomatic patients showed neurological signs and/or symptoms at birth; brain imaging analysis showed recurrent neuroradiological abnormalities in congenital CMV infection.

Objective: To evaluate the incidence and evolution of isolated sensorineural hearing loss (SNHL) at birth in a population of newborns with congenital cytomegalovirus (cCMV) infection. Materials and methods: This prospective, single-center study was conducted at a university hospital. Fifty-five full-term newborns with asymptomatic cCMV infection, born between January 2011 and March 2020, without additional risk factors for hearing loss and who presented with bilateral “pass” otoacoustic emissions (OAE) after birth, were included. None received antiviral therapy. Hearing thresholds were repeatedly assessed by auditory evoked potentials with threshold search (ABR). Infants with SNHL were followed until possible normalization of hearing thresholds (“maturative” SNHL) or definitive diagnosis of SNHL (“true” SNHL). The worse ear was taken into account for severity classification. Results: Hearing loss was diagnosed in 18/55 (32.7%) infants at first ABR; mild in eleven cases (2/11 bilateral), moderate in four cases (3/4 bilateral) and severe in three (1/3 bilateral). One patient out of 18 developed “true” SNHL, while 17/18 spontaneously recovered a normal hearing threshold over time. Overall, the prevalence of “true” SNHL was 1.8%, 95% confidence interval (CI) = 0.06–12.30%. The first ABR was performed at a mean age of 3.35 ± 2.3 months in the 18 infants with SNHL; in the 37 newborns with normal hearing thresholds the age at first ABR was significantly different (p = 0.005 (5.8 ± 2.6 months). Conclusion: In cCMV infection, auditory neuropathy isolated at birth is mainly due to a delay in maturation of the auditory pathways that resolves spontaneously over time. This should be taken into account to avoid unnecessary and potentially harmful antiviral therapy.
