description: We substitute the fully absorbing obstacle in the Elitzur-Vaidman experiment by a semitransparent object and show that the probabilities of detection can be manipulated in dependence of the transparency of such an object. Then, we connect our results with the delayed choice experiment proposed by Wheeler. It is found that the transparency of the obstacle determines either a particle-like or a wave-like behaviour of a test photon.
Non-radial pulsation in first overtone Cepheids of the Small Magellanic Cloud

description: We analyse photometry for 138 first overtone Cepheids from the Small Magellanic Cloud, in which Optical Gravitational Lensing Experiment (OGLE) team discovered additional variability with period shorter than first overtone period, and period ratios in the (0.60, 0.65) range. In the Petersen diagram these stars form three well separated sequences. The additional variability cannot correspond to other radial mode. This form of pulsation is still puzzling. We find that amplitude of the additional variability is small, typically 2-4 per cent of the first overtone amplitude, which corresponds to 2-5 mmag. In some stars we find simultaneously two close periodicities corresponding to two sequences in the Petersen diagram. The most important finding is the detection of power excess at half the frequency of the additional variability (at subharmonic) in 35 per cent of the analysed stars. Interestingly, power excess at subharmonic frequency is detected mostly for stars of the middle sequence in the Petersen diagram (74 per cent), incidence rate is much lower for stars of the top sequence (31 per cent), and phenomenon is not detected for stars of the bottom sequence. The amplitude and/or phase of the additional periodicities strongly vary in time. Similar form of pulsation is observed in first overtone RR Lyrae stars. Our results indicate that the nature and cause of this form of pulsation is the same in the two groups of classical pulsators; consequently, a common model explaining this form of pulsation should be searched for. Our results favour the theory of the excitation of non-radial modes of angular degrees 7, 8 and 9, proposed recently by Dziembowski.

title: A legal framework for a climate neutral built environment? Open legal issues in the building related climate protection regime
Creators: name: Wagner, Dominik Alexander
Publisher: name: TU Wien
Year: 2023
Subjects: environmental law

description: This presentation addressed current legal issues related to the challenges posed by the sustainability transformation of the building sector. Taking the EU's current energy and climate policies as a starting point, Austria was used as an example to show how these endeavours are reflected in building and planning law. Which parts of the legal order have already been adapted to the key targets of the EU energy and climate policy and where is there a need for further action? A key thesis is that the current law cannot currently do justice to the necessity of transformation, as it has so far completely excluded urgent questions regarding embodied energy and emissions and the use of scarce resources. A certain reorientation of building and planning law is needed, including innovative legal instruments.

description: Recent developments of the multiplex paradigm included efforts to understand the role played by the presence of several layers on the dynamics of processes running on these networks. The possible existence of new phenomena associated to the richer topology has been discussed and examples of these differences have been systematically searched. Here, we show that the interconnectivity of the layers may have an important impact on the speed of the dynamics run in the network and that microscopic changes such as the addition of one single inter-layer link can notably affect the arrival at a global stationary state. As a practical verification, these results obtained with spectral techniques are confirmed with a Kuramoto dynamics for which the synchronization consistently delays after the addition of single inter-layer links.

description: Weak bases of relational clones have been used in the past as a theoretical tool to establish more fine-grained complexity analyses of computational problems, see, e.g., [6, 1, 5, 8, 3]. For the Boolean case weak bases have been determined by Lagerkvist in [7], see also the discussion in [2]. The quest for weak bases on sets of larger size was begun in [4] with a study of weak bases for maximal clones, resulting in a complete description for all maximal clones on a three-element set. We shall report on extending this work to all maximal clones on any finite set. References: [1] M. Behrisch, M. Hermann, S. Mengel, and G. Salzer.

description: Compact binary system mergers are expected to generate gravitational radiation detectable by ground-based interferometers. A subset of these, the merger of a neutron star with another neutron star or a black hole, are also the most popular model for the production of short gamma-ray bursts (GRBs). The Swift Burst Alert Telescope (BAT) and the Fermi Gamma-ray Burst Monitor (GBM) trigger on short GRBs (SGRBs) at rates that reflect their relative sky exposures, with the BAT detecting 10 per year compared to about 45 for GBM. We examine the SGRB populations detected by Swift BAT and Fermi GBM. We find that the Swift BAT triggers on weaker SGRBs than Fermi GBM, providing they occur close to the center of the BAT field-of-view, and that the Fermi GBM SGRB detection threshold remains flatter across its field-of-view. Overall, these effects combine to give the instruments the same average sensitivity, and account for the SGRBs that trigger one instrument but not the other. We do not find any evidence that the BAT and GBM are detecting significantly different populations of SGRBs. Both instruments can detect untriggered SGRBs using ground searches seeded with time and position. The detection of SGRBs below the on-board triggering sensitivities of Swift BAT and Fermi GBM increases the possibility of detecting and localizing the electromagnetic counterparts of gravitational wave events seen by the new generation of gravitational wave detectors.

description: Propagating slow waves in coronal loops exhibit a damping which depends upon the frequency of the waves. In this study we aim to investigate the relationship of the damping length (L$_d$) with the frequency of the propagating wave. We present a 3-D coronal loop model with uniform density and temperature and investigate the frequency dependent damping mechanism for the four chosen wave periods. We include the thermal conduction to damp the waves as they propagate through the loop. The numerical model output has been forward modelled to generate synthetic images of SDO/AIA 171 Å and 193 Å channels. The use of forward modelling, which incorporates the atomic emission properties into the intensity images, allows us to directly compare our results with the real observations. The results show that the damping lengths vary linearly with the periods. We also measure the contributions of the emission properties on the damping lengths by using density values from the simulation. In addition to that} we have also calculated the theoretical dependence of L$_d$ with wave periods and showed that it is consistent with the results we obtained from the numerical modelling and earlier observations.

Omitting testing a face mask ventilation in patients without difficult airway
Creators: name: Siutsou, Pavel
Publisher: name: No Publisher Supplied
Year: 2023

description: Background: During induction of general anesthesia, the classic anesthesia teaching suggests that a neuromuscular blocker (NMB) should not be given before ensuring the ability of face mask ventilation (FMV). If FMV cannot be established, a supraglottic airway insertion, endotracheal intubation, or awakening the patient are the suggested options. Studies confirm that ventilation is often easier after the NMB is administered. With advancements in video laryngoscopy, supraglottic airways, and new reversal agents, there is no longer a need to delay NMB to establish the ability to FMV the patient. Purpose: The purpose of this project is to evaluate and reduce a knowledge gap regarding the safety of omitting FMV checks before the administration of NMB among anesthesia providers. Methodology: A pretest was administered to physician anesthesiologists and certified registered nurse anesthesiologists (CRNA) at a large teaching hospital in central New Jersey via email. The educational presentation was provided, and the posttest was given immediately after. One month later, another survey was sent to assess change in practice. Results: Ten participants completed all three surveys. The initial pretest identified that 60% of participants checked their ability to ventilate “most of the time” or “always” before and only 10% one month after the intervention. For the central question: “Do you consider practicing by injecting NMBs without testing the ability to face mask ventilate the patient?”, only 30% said “definitely yes” before intervention and 90% one-month post-intervention. There was a statistically significant change in responses between the pretest, immediate posttest, and one-month posttest regarding skipping FMV check by anesthesia providers X2(2) = 11.565, p = 0.003. Post hoc analysis with Wilcoxon Signed Rank Test with Bonferroni correction showed that the quality improvement project produced a statistically significant change in responses between the pretest and one-month posttest (Z = -2.460, p = 0.014).Implications: This project determined the knowledge gap in providers regarding the early administration of neuromuscular blockers. New knowledge will help improve the quality of care provided to patients undergoing procedures requiring general anesthesia. CRNAs and physician anesthesiologists can educate residents and colleagues about the safety of NMB administration without delay for FMV check

description: Background: Accurate assessment of prescription drug misuse (PDM) is critical among young-adult college students, a particularly high-risk group for this substance behavior. No studies have compared assessments of college students’ reports of PDM obtained from their reporting in daily life (via ecological momentary assessment; EMA) to their retrospective accounts of PDM over the same period (via timeline follow-back interview; TLFB), an approach that is commonly used in substance use research. Purpose/Objectives: To determine day-level agreement and person-level agreement in college student reports of PDM in EMA versus TLFB methods. Methods: Participants were 297 college freshmen and sophomores (69% female) recruited based on misuse behavior in the past three months. PDM behaviors were captured in daily life using EMA for 28 days and TLFB administered during an in-person lab visit. Agreement was assessed at the person level (any PDM during the 28 days) and day level (PDM on a given day) using Cohen’s kappa and percent agreement. Results: PDM was reported more frequently using TLFB compared to EMA. Person-level agreement between the two methods was good (k = 0.62, 95% CI: 0.53, 0.70), whereas day-level agreement was fair (k = 0.23, 95% CI: 0.19, 0.28). Agreement in stimulant misuse reported across methods was more consistent compared to reports of other medication classes. Conclusions: Findings offer implications for the assessment of college student PDM data in substance use research.

description: The TauSpinner algorithm allows to modify the physics of the Monte Carlo generated samples due to the changed assumptions of event production dynamics, without re-generating events. To each event it attributes weights: the spin effects of tau-lepton production or decay, or the production mechanism are modified. There is no need to repeat the detector response simulation. We document the extension to 2 to 4 processes in which the matrix elements for the parton-parton scattering amplitudes into a tau-lepton pair and two outgoing partons are used. Tree-level matrix elements for the Standard Model processes, including the Higgs boson production are used. Automatically generated codes by MadGraph5 have been adapted. Tests of the matrix elements, reweighting algorithm and numerical results are presented. For averaged tau lepton polarisation, we perform comparison of 2 to 2 and 2 to 4 matrix elements used to calculate the spin weight in pp to tau tau j j events. We show, that for events with tau-lepton pair close to the Z-boson peak, the tau-lepton polarisation calculated using 2 to 4 matrix elements is very close to the one calculated using 2 to 2 Born process only. For the m_(tautau) masses above the Z-boson peak, the effect from including 2 to 4 matrix elements is also marginal, however when restricting into subprocesses qq,q bar q to tau tau j j only, it can lead to a 10% difference on the predicted tau-lepton polarisation. Choice of electroweak scheme can have significant impact. The modification of the electroweak or strong interaction can be performed with the re-weighting technique. TauSpinner v.2.0.0, allows to introduce non-standard couplings for the Higgs boson and study their effects in the vector-boson-fusion. The discussion is relegated to forthcoming publications.

description: By combining a tilted-pulse-intensity-front scheme using a LiNbO3 crystal and a chirped-pulse-beating method, we generated a narrowband intense terahertz (THz) pulse, which had a maximum electric field of more than 10 kV/cm at around 2 THz, a bandwidth of about 50 GHz,and frequency tunability from 0.5 to 2 THz. By performing THz-pump and near-infrared-probe experiments on GaAs quantum wells, we observed that the resonant excitation of the intraexcitonic 1s-2p transition induces a clear and large Autler-Townes splitting. Our time-resolved measurements show that the splitting energy observed in the rising edge region of electric field is larger than in the constant region. This result implies that the splitting energy depends on the time-averaged THz field over the excitonic dephasing time rather than that at the instant of the exciton creation by a probe pulse.

description: Magnetic skyrmions have attracted broad attention during recent years because they are regarded as promising candidates as bits of information in novel data storage devices. A broad range of theoretical and experimental investigations have been conducted with the consideration of rotational symmetric skyrmions in isotropic environments. However, one naturally observes a huge variety of anisotropic behavior in many experimentally relevant materials. In the present work, we investigate the influence of anisotropic environments onto the formation and behavior of the non-collinear spin states of skyrmionic materials by means of Monte-Carlo calculations. We find skyrmionic textures which are far from having a rotational symmetric shape. Furthermore, we show the possibility to employ periodic modulations of the environment to create skyrmionic tracks.

description: Background and Objectives: Better understanding of predictors of opioid abstinence among patients with opioid use disorder (OUD) may help to inform interventions and personalize treatment plans. This analysis examined patient characteristics associated with opioid abstinence in the X:BOT (Extended-Release Naltrexone versus Buprenorphine for Opioid Treatment) trial. Methods: This post-hoc analysis examined factors associated with past-month opioid abstinence at the 36-week follow-up visit among participants in the X:BOT study. 428 participants (75% of original sample) attended the visit at 36 weeks. Logistic regression models were used to estimate the probability of opioid abstinence across various baseline sociodemographics, clinical characteristics, and treatment variables. Results: Of the 428 participants, 143 (33%) reported abstinence from non-prescribed opioids at the 36-week follow-up. Participants were more likely to be opioid abstinent if randomized to XR-NTX (compared to BUP-NX), were on XR-NTX at week 36 (compared to those off OUD pharmacotherapy), successfully inducted onto either study medication, had longer time on study medication, reported a greater number of abstinent weeks, or had longer time to relapse during the 24-week treatment trial. Participants were less likely to be abstinent if Hispanic, had a severe baseline Hamilton Depression Rating (HAM-D) score, or had baseline sedative use. Conclusions: A substantial proportion of participants was available at follow-up (75%), was on OUD pharmacotherapy (53%), and reported past-month opioid abstinence (33%) at 36 weeks. A minority of patients off medication for OUD reported abstinence and additional research is needed exploring patient characteristics that may be associated with successful treatment outcomes.

description: Studying fluctuations of conserved quantities, such as baryon number, strangeness, and charge, provides insights into the properties of matter created in high-energy nuclear collisions. Lattice QCD calculations suggest that higher moments of these quantities are sensitive to the phase structure of the hot and dense nuclear matter created in such collisions. In this paper, we present first experimental results of volume and temperature independent cumulant ratios of net-charge and net-proton distributions in Au+Au collisions at $\sqrt{s_{\rm NN}}\!=\!14.5 \,{\rm GeV}$ completing the first RHIC Beam Energy Scan (BES-I) program for $\sqrt{s_{\rm NN}}\!=\!7.7 \,{\rm to}\,200\,{\rm GeV}$, together with the first measurement of fully corrected net-kaon results, measured with the STAR detector at RHIC at mid-rapidity and a transverse momentum up to $p_{\rm T}\!=\!2\,{\rm GeV/{\it c}}$. The pseudo-rapidity dependence of the $\sqrt{s_{\rm NN}}\!=\!14.5 \,{\rm GeV}$ net-charge cumulant ratios is discussed. The estimated uncertainties on the ratio $c_4/c_2$, the most statistics-hungry of the present observables, at $\sqrt{s_{\rm NN}}\!=\!7.7 \,{\rm GeV}$ in the upcoming RHIC BES-II program will also be presented.

IN SITU PREPARATION OF NON HALOGENATED FLAME RETARDANT POLYAMIDES
Creators: name: LUGATO, TOMMASO
Publisher: name: Universit� degli Studi di Milano

description: In this research project the work was focused on the development of flame retardant polyamides by using two different approaches: the copolymerization with phosphor-containing molecules (one of the most promising class of NHFR) and the insertion of surface-modified mineral nanoparticles (another class of NHFR with high potential interest). The choice of polyamide is owed to the fact that an high amount of this material needs flame retardant property, considering its use in moulded manufactured articles with application in risk conditions (electric covering, control units..) and its use in the production of fibre (carpeting, drapery..) that should need a specific flame retardant material (obtainable by copolymerization because compounded materials aren?t usable) that doesn?t exist on the market (while there is an example of a PET FR[4]). Regarding intellectual property there are some patents[5] on the use of a minimal quantity of phosphor-based comonomers in copolymerization with nylon 66; however at the beginning of the PhD, there weren?t on the market polymeric materials obtained according to these patents. Polyamide 6 has been chosen because it is a commodity obtained by polymerization of an ?-amino acid; this kind of polymerization gives less problems in comparison with a polycondensation of a diacid and a diamine (i.e gelification problems), allowing a better study of copolymerization.

description: The semiconductor polariton laser promises a new source of coherent light, which, compared to conventional semiconductor photon lasers, has input-energy threshold orders of magnitude lower. However, intensity stability, a defining feature of a coherent state, has remained poor. Intensity noise at many times of the shot-noise of a coherent state has persisted, which has been attributed to multiple mechanisms that are difficult to separate in conventional polariton systems. The large intensity noise in turn limited the phase coherence. These limit the capability of the polariton laser as a source of coherence light. Here, we demonstrate a polariton laser with shot-noise limited intensity stability, as expected of a fully coherent state. This is achieved by using an optical cavity with high mode selectivity to enforce single-mode lasing, suppress condensate depletion, and establish gain saturation. The absence of spurious intensity fluctuations moreover enabled measurement of a transition from exponential to Gaussian decay of the phase coherence of the polariton laser. It suggests large self-interaction energies in the polariton condensate, exceeding the laser bandwidth. Such strong interactions are unique to matter-wave laser and important for nonlinear polariton devices. The results will guide future development of polariton lasers and nonlinear polariton devices.

There are now several collections of this species from the neighboring Provinces of La Unión and Condesuyos in Department Arequipa. The collections from La Unión, unfortunately have no collector nor collection number and are housed in the herbarium of the Universidad de San Augustin in Arequipa only. It is somewhat surprising that the species appears to be disjunct between Tarapacá in northern Chile and the northern part of the Department of Arequipa in Peru, but so far no collections have emerged from the southern part of Department Arequipa nor the Departments Moquegua and Tacna.

description: Dust scattering is the main source of diffuse emission in the far-ultraviolet (FUV). For several locations in the Large Magellanic Cloud (LMC), Far Ultraviolet Spectroscopic Explorer (FUSE) satellite has observed diffuse radiation in the FUV with intensities ranging from 1000 - 3 X 10^5 photon units and diffuse fraction between 5% - 20% at 1100 °A. Here, we compare the FUV diffuse emission with the mid-infrared (MIR) and far-infrared (FIR) diffuse emission observed by the Spitzer Space Telescope and the AKARI satellite for the same locations. The intensity ratios in the different MIR and FIR bands for each of the locations will enable us to determine the type of dust contributing to the diffuse emission as well as to derive a more accurate 3D distribution of stars and dust in the region, which in turn may be used to model the observed scattering in the FUV. In this work we present the infrared (IR) data for two different regions in LMC, namely N11 and 30 Doradus. We also present the FUV~IR correlation for different infrared bands.

description: I report on the progress of two new muon anomalous magnetic moment experiments, which are in advanced design and construction phases. The goal of Fermilab E989 is to reduce the experimental uncertainty of $a_μ$ from Brookhaven E821 by a factor of 4; that is, $δa_μ\sim 16 \times 10^{-11}$, a relative uncertainty of 140~ppb. The method follows the same magic-momentum storage ring concept used at BNL, and pioneered previously at CERN, but muon beam preparation, storage ring internal hardware, field measuring equipment, and detector and electronics systems are all new or upgraded significantly. In contrast, J-PARC E34 will employ a novel approach based on injection of an ultra-cold, low-energy, muon beam injected into a small, but highly uniform magnet. Only a small magnetic focusing field is needed to maintain storage, which distinguishes it from CERN, BNL and Fermilab. E34 aims to roughly match the previous BNL precision in their Phase~1 installation.

description: We present a detailed statistical analysis of possible non-linearities in the Period-Luminosity (P-L), Period-Wesenheit (P-W) and Period-Color (P-C) relations for Cepheid variables in the LMC at optical ($VI$) and near-infrared ($JHK_{s}$) wavelengths. We test for the presence of possible non-linearities and determine their statistical significance by applying a variety of robust statistical tests ($F$-test, Random-Walk, Testimator and the Davies test) to optical data from OGLE III and near-infrared data from LMCNISS. For fundamental-mode Cepheids, we find that the optical P-L, P-W and P-C relations are non-linear at 10 days. The near-infrared P-L and the $W^H_{V,I}$ relations are non-linear around 18 days; this break is attributed to a distinct variation in mean Fourier amplitude parameters near this period for longer wavelengths as compared to optical bands. The near-infrared P-W relations are also non-linear except for the $W_{H,K_s}$ relation. For first-overtone mode Cepheids, a significant change in the slope of P-L, P-W and P-C relations is found around 2.5 days only at optical wavelengths. We determine a global slope of $\textrm{-}3.212\pm0.013$ for the $W^H_{V,I}$ relation by combining our LMC data with observations of Cepheids in Supernovae host galaxies \citep{riess11}. We find this slope to be consistent with the corresponding LMC relation at short periods, and significantly different to the long-period value. We do not find any significant difference in the slope of the global-fit solution using a linear or non-linear LMC P-L relation as calibrator, but the linear version provides a $2\times$ better constraint on the slope and metallicity coefficient.

DNP project: Evaluation of point-of-care ultrasound training program for certified registered nurse anesthetists
Creators: name: Modh, Ravi

description: Purpose of Project: Obtaining vascular access is an essential skill for every CRNA. Gaining access can be challenging in some patients, yet CRNA’s tend to use traditional methods, resulting in multiple failed sticks and delays in care. Literature supports using point-of-care ultrasound (POCUS) techniques to gain access in these patient populations. It also supports the efficacy of teaching POCUS using a didactic and a simulation component. The aim of this project was to decrease failed cannulation attempts by increasing POCUS use and to improve first attempt successful cannulation rate by CRNA’s for peripheral IV and A-line insertions. Methodology: This quality improvement project implemented a multimodal hands-on simulation ultrasound workshop for CRNA’s focusing on the Dynamic Needle Tip Positioning (DNTP) technique. Fifteen CRNA’s were given a didactic lecture, followed by a hands-on simulation workshop. During the workshop, participants used POCUS to identified vascular anatomy on humans and then cannulated a gelatin phantom model using the DNTP technique. Participants responded to pre- and post-workshop surveys. Results: Following the workshop, there was a significant increase in the number of times the CRNA’s used POCUS in the clinical setting to attempt vascular access (p=0.042). Additionally, participants successfully identified barriers to using ultrasound in their respective clinical settings. Some objectives were not met with statistical significance. Implications for Practice: Objectives that were not met and barriers that were identified will offer guidance for future scholarship development.
