description: We propose a four-loop induced radiative neutrino mass model inspired by the diphoton excess at 750 GeV recently reported by ATLAS and CMS, in which a sizable diphoton excess is obtained via photon fusion introducing multi doubly-charged scalar bosons. Also we discuss the muon anomalous magnetic moment, and a dark matter candidate. The main process to explain the observed relic density relies on the final state of the new particle at 750 GeV. Finally we show the numerical results and obtain allowed region of several physical values in our model.

Are Incoherent Operations Physically Consistent? -- A Critical Examination of Incoherent Operations

Year: 2016

description: Considerable work has recently been directed toward developing resource theories of quantum coherence. In most approaches, a state is said to possess quantum coherence if it is not diagonal in some specified basis. In this letter we establish a criterion of physical consistency for any resource theory in terms of physical implementation of the free operations, and we show that all currently proposed basis-dependent theories of coherence fail to satisfy this criterion. We further characterize the physically consistent resource theory of coherence and find its operational power to be quite limited. After relaxing the condition of physical consistency, we introduce the class of dephasing-covariant incoherent operations, present a number of new coherent monotones based on relative Rényi entropies, and study incoherent state transformations under different operational classes. In particular, we derive necessary and sufficient conditions for qubit state transformations and show these conditions hold for all classes of incoherent operations.

description: One of the primary objectives outlined in the ALMA Development Roadmap is to broaden the Intermediate Frequency (IF) bandwidth of the receivers for improved sensitivity. A crucial element in achieving this goal is the Cryogenic Low Noise IF Amplifier (CLNA), which necessitates an upgrade. The current generation of ALMA receivers in the most advanced bands offers two polarizations and two sidebands, delivering an instantaneous IF bandwidth of 8 GHz (per polarization and per sideband in the 4-12 GHz range). Our ambitious aim in facilitating this upgrade was to demonstrate the feasibility of doubling the maximum instantaneous IF bandwidth (4-20 GHz) while preserving or improving the characteristics of existing amplifiers. An additional challenge involved obtaining amplifiers with low input reflection as it was anticipated that the devices used in the current receiver generation to mitigate reflection issues (isolators) would be challenging to obtain. Achieving low reflection was essential for ensuring good rejection of undesired sidebands in 2SB receivers, yet this conflicted with the imperative to obtain very low noise. Another significant constraint was the need for the amplifiers to have low power dissipation, given the limited cooling capacity of the receiver cryostat. The development of these amplifiers has proven successful, meeting all specified requirements. Several demonstration prototypes have been built, and the results will be presented during the upcoming meeting.

description: The Compact Muon Solenoid (CMS) is a general purpose detector, designed to run at the highest luminosity at the CERN Large Hadron Collider (LHC). Its distinctive features include a 4 T superconducting solenoid with 6-m-diameter by 12.5-m-length free bore, enclosed inside a 10,000-ton return yoke made of construction steel. The return yoke consists of five dodecagonal three-layered barrel wheels and four end-cap disks at each end comprised of steel blocks up to 620 mm thick, which serve as the absorber plates of the muon detection system. To measure the field in and around the steel, a system of 22 flux loops and 82 3-D Hall sensors is installed on the return yoke blocks. A TOSCA 3-D model of the CMS magnet is developed to describe the magnetic field everywhere outside the tracking volume measured with the field-mapping machine. The first attempt is made to measure the magnetic flux density in the steel blocks of the CMS magnet yoke using the standard magnet discharge with the current ramp down speed of 1.5 A/s.

description: The thermal reactions of [Zn(OH)]+ with C3H8 have been studied by means of gas-phase experiments and computational investigation. Two types of C–H bond activation are observed in the experiment, and pertinent mechanistic features include inter alia: (i) the metal center of [Zn(OH)]+ serves as active site in the hydride transfer to generate [i-C3H7]+ as major product, (ii) generally, a high regioselectivity is accompanied by remarkable chemoselectivity: for example, the activation of a methyl C–H bond results mainly in the formation of water and [Zn(C3,H7)]+. According to computational work, this ionic product corresponds to [HZn(CH3CH[double bond, length as m-dash]CH2)]+. Attack of the zinc center at a secondary C–H bond leads preferentially to hydride transfer, thus giving rise to the generation of [i-C3H7]+; (iii) upon oxidative dehydrogenation (ODH), liberation of CH3CH2[double bond, length as m-dash]CH2 occurs to produce [HZn(H2O)]+. Both, ODH as well as H2O loss proceed through the same intermediate which is characterized by the fact that a methylene hydrogen atom from the substrate is transferred to the zinc and one hydrogen atom from the methyl group to the OH group of [Zn(OH)]+. The combined experimental/computational gas-phase study of C–H bond activation by zinc hydroxide provides mechanistic insight into related zinc-catalyzed large-scale processes and identifies the crucial role that the Lewis-acid character of zinc plays.

description: Recent tremendous development of quantum information theory led to a number of quantum technological projects, e.g., quantum random generators. This development stimulates a new wave of interest in quantum foundations. One of the most intriguing problems of quantum foundations is elaboration of a consistent and commonly accepted interpretation of quantum state. Closely related problem is clarification of the notion of quantum randomness and its interrelation with classical randomness. In this short review we shall discuss basics of classical theory of randomness (which by itself is very complex and characterized by diversity of approaches) and compare it with irreducible quantum randomness. The second part of this review is devoted to the information interpretation of quantum mechanics (QM) in the spirit of Zeilinger and Brukner (and QBism of Fuchs et al.) and physics in general (e.g., Wheeler's "it from bit") as well as digital philosophy of Chaitin (with historical coupling to ideas of Leibnitz). Finally, we continue discussion on interrelation of quantum and classical randomness and information interpretation of QM.

The ALMA20230 Wideband Sensitivity Upgrade (WSU) - Status Update
Creators: name: González, Álvaro
Publisher: name: Zenodo
Year: 2024

description: ALMA has been producing ground-breaking science since it became operative in 2011. The ALMA Development Roadmap was released in 2018 to prioritize the development necessary to significantly expand ALMA's capabilities and enable it to produce even more exciting science in the coming decades. The ALMA2030 Wideband Sensitivity Upgrade (WSU) is the top priority initiative for the Development Roadmap. The WSU will initially double, and eventually quadruple, ALMA's system instantaneous bandwidth and deliver improved sensitivity by upgrading the receivers, digital electronics, and correlator. The WSU will afford significant improvements for every future ALMA observation, whether it is focused on continuum or spectral line science. The improved sensitivity and spectral tuning grasp will open new avenues of exploration, increase sample sizes, and enable more efficient observations. The WSU is now well underway with key subsystem under development, including new receivers, digitizers, data transmission system and correlator. In parallel, the observatory is advancing the detailed planning towards implementation through a careful project management and systems engineering approach, based on an integrated Conceptual System Design which outlines the hardware, software / computing and science operations aspects of the upgrade. The substantial gains in the observing efficiency enabled by the WSU will further enhance ALMA as the world leading facility for millimeter/submillimeter astronomy.

description: The article describes the results of the online survey on open science (OS) carried out on researchers affiliated with universities and Spanish research performing organisations (RPOs) and focused on open access to scientific publications, the publication process, the management of research data and the review of open articles. The main objective was to identify the perception and habits of researchers with regard to practices closely linked to open science. to offer an in-depth picture of researchers as one of the main actors to whom this transformation and implementation of open science will fall. It focuses on the different aspects of OS: open access, open data, publication process and open review in order to identify habits and perceptions. The results showed that open access still requires the dissemination of practices and services provided by the institution, including training activities (library or equivalent service) and institutional support from the competent authorities (vice-rectors or equivalent) in specific aspects such as data management. In the case of data, around 50% of respondents stated they had archived data in a repository, and of all the options, the most frequently given was that of an institutional repository, followed by a discipline repository. Among the main reasons for doing this, we found transparency, visibility of data and the ability to validate results. For those who stated they had never archived data, the most frequent reasons for not having done so were privacy and confidentiality issues, the lack of a mandated data policy or a lack of knowledge of how to do it. In terms of open peer review, participants mentioned a certain reticence to the opening of evaluations due to potential conflicts of interest that may arise or because lower-quality content might be accepted in order to avoid conflicts. In addition, the hierarchical structure of senior researcher versus junior researcher might affect reviews. The main conclusions indicate the need for persuasion of OA to take place; APCs are an economic barrier rather than the main criterion for journal selection; OPR practices may seem innovative and emerging; scientific and evaluation policies seem to have a clear effect on the behaviour of researchers; researchers state that they share research data more for reasons of persuasion than out of obligation. Researchers do question the pathways or difficulties that may arise on a day-to-day basis and seem aware that we are undergoing change, where academic evaluation or policies related to open science, its implementation and habits among researchers may change. In this sense, more and better support is needed on the part of institutions and faculty support services.

3D hydrodynamic modelling of the circulation dynamics and dilution in Hendrix Creek, New York
Creators: name: Akpan, Oto-Obong
Publisher: name: No Publisher Supplied
Year: 2022

description: The ambient conditions of receiving waters such as currents and density stratification have been shown to influence the dilution of treated wastewater discharged by WWTPs. In order to better understand the ambient conditions, particularly the circulation dynamics, which contributes to adequate dilution, a comprehensive hydrodynamic study of the receiving environment, using tracers to simulate treated wastewater and assess dilution, can be employed as an effective strategy. In this paper the mechanisms driving the estuarine circulation, which contributes to dilution in Hendrix Creek were studied by utilizing a validated 3D numerical hydrodynamics model (Delft3D FM). Hendrix Creek, a semi enclosed tidal tributary of Jamaica Bay that serves as a receiving water of 26th Ward WRRF, is not well studied. Furthermore, the transport regime of the WRRF discharge as well as the dilution and mixing conditions are unclear despite it being a permitted discharge through NYSDEC. Therefore, field measurements of the ambient environment as well as dilution studies using a tracer dye injected into the plant effluent were conducted, which aided in the calibration of the model. The model utilized field-collected bathymetry, tidal forcings, and freshwater input, as well as a k-e turbulence closure scheme. In addition to the developed model, numerical scenarios were performed during the second dye study period to better understand the significance of plant outfall location, bathymetry and freshwater discharge from CSO on the dilution of treated wastewater. Furthermore, a tidal decomposition of the salt and dye fluxes was conducted to determine the magnitudes of the dominant mechanisms in the circulation and transport of treated wastewater in Hendrix Creek. It was discovered that the main mechanisms involved in the estuarine circulation are the mean advection due to the freshwater discharge from the plant and the residual circulation, which both serve in maintaining the salt balance in the creek. An estimated dilution factor of 1.3 was computed in the receiving environment of the plant discharge, which indicates poor dilution. Numerical experiments of alternative outfall configurations confirm that vertical circulation is important for adequate dilution. However, the current ambient conditions and bathymetry of Hendrix Creek deter the mixing and circulation potential necessary for dilution of the treated wastewater. Therefore, alternative measures such as dredging as well as some regulatory changes to the discharge permit should be considered to improve overall dilution and water quality of the creek.

description: We consider a one-dimensional sandpile model which mimics an elastic string of particles driven through a strongly pinning periodic environment with phase disorder. The evolution towards depinning occurs by the triggering of avalanches in regions of activity which are at first isolated but later grow and merge. For large system sizes the dynamically critical behavior is dominated by the coagulation of these active regions. Our analysis of the evolution and numerical simulations show that the observed sizes of active regions is well-described by a Smoluchowski coagulation equation, allowing us to predict correlation lengths and avalanche sizes.

description: Parents and community members have a wide variety of information at their disposal when evaluating educational quality. Message boards, government-provided information on standardized test scores and student demographics, and privately-provided quality assessments, such as the high-profile GreatSchools ratings, are just some of the information sources that individuals use to assess school quality and guide residential location and enrollment decisions. Scholars have investigated which sources of information have the largest impact on enrollment decisions (e.g., \citet{Valant_Newark_2020}). We are interested in whether different reference frames for understanding school quality affect the type of information individuals use when evaluating schools and making enrollment decisions. To explore this, we develop four information-provision interventions that direct individuals' attention to different aspects of school quality. Using conjoint experiments, we investigate how each of the interventions affects the responsiveness of enrollment choice decisions to demographic composition, standardized test score averages, and measures of student growth from standardized test scores. The results have important implications for understanding how parents and community members evaluate school quality and can inform policy decisions regarding the presentation of information about educational performance.
Ukrainian Journal Publishing: a Lost Battle on the Way to Open Access?
Creators: name: Nazarovets, Maryna
Publisher: name: Zenodo
Year: 2023

description: This poster presents a preliminary analysis of the key factors that reflect the current state of Ukrainian scholarly journal publishing with a focus on the challenges and obstacles they face on the way to transition to Open Access (OA), as well as an analysis of existing initiatives and strategies in the field of OA journal publishing in the country. The Ukrainian research community has been trying to move towards OA for years. Despite the efforts of various stakeholders, including universities, libraries, research institutions and government agencies, preliminary findings suggest that the country is not doing well in this area (Novikov, 2020). For example, according to various national sources, from 1500 to almost 3000 journals are published in Ukraine, but only about 27% are represented in the DOAJ (Laakso & Multas, 2023). Does this number represent the reality? What publishing model, as opposed to OA, do most Ukrainian journals prefer and why? This poster highlights the main reasons for the situation with the perception and implementation of OA journal publishing in Ukraine, such as low awareness of researchers and publishers of its organisational features, including legal and financial, and the lack of justification and chaotic government initiatives for its implementation. Thus, among the latest initiatives of the Ukrainian government was the introduction of the National Open Science Action Plan on 8 October 2022 (Nazarovets, 2022). This plan, among other things, contains unexpected goals to register 40 Ukrainian journals with the DOAJ in 2024. Given the overall picture of journal publishing in Ukraine, this goal raises many questions. By identifying key factors that reflect the current state of OA journal publishing in Ukraine, the poster aims to contribute to the discussion on the need for more clear, reasonable, and controlled plans for the development of scholarly communication in Ukraine and beyond, with the introduction of new emerging publishing models and based on the experience of successful global initiatives, taking into account regional specifics.

description: We introduce a new learned descriptor for audio signals which is efficient for event representation. The entries of the descriptor are produced by evaluating a set of regressors on the input signal. The regressors are class-specific and trained using the random regression forests framework. Given an input signal, each regressor estimates the onset and offset positions of the target event. The estimation confidence scores output by a regressor are then used to quantify how the target event aligns with the temporal structure of the corresponding category. Our proposed descriptor has two advantages. First, it is compact, i.e. the dimensionality of the descriptor is equal to the number of event classes. Second, we show that even simple linear classification models, trained on our descriptor, yield better accuracies on audio event classification task than not only the nonlinear baselines but also the state-of-the-art results.

description: Circumbinary planets experience a time varying irradiation pattern as they orbit their two host stars. In this work, we present the first detailed study of the atmospheric effects of this irradiation pattern on known and hypothetical gaseous circumbinary planets. Using both a one-dimensional Energy Balance Model and a three-dimensional General Circulation Model, we look at the temperature differences between circumbinary planets and their equivalent single-star cases in order to determine the nature of the atmospheres of these planets. We find that for circumbinary planets on stable orbits around their host stars, temperature differences are on average no more than 1.0% in the most extreme cases. Based on detailed modeling with the General Circulation Model, we find that these temperature differences are not large enough to excite circulation differences between the two cases. We conclude that gaseous circumbinary planets can be treated as their equivalent single-star case in future atmospheric modeling efforts.

Year: 2024

description: In the last quarter of 2022, the NOVA Sub-mm Instrumentation Group (University of Groningen) finalized an ESO-cofunded study on the possibility of upgrading the current ALMA double sideband (DSB) Band 9 (602-720GHz) receivers to a sideband-separating (2SB) architecture. Besides the 2SB conversion itself, several other enhancements in line with the ALMA2030 roadmap were studied, in particular aspects of the Wideband Sensitivity Upgrade (WSU). A proof-of-concept Band 9 2SB mixer with an IF band of 4-20 GHz was demonstrated. Compared to the 4-12 GHz IF of the existing DSB Band 9 receivers, this represents a fourfold increase in exported IF bandwidth (from 2 x 8 GHz to 4 x 16 GHz). Another subject that was studied was the possibility to enhance the polarimetric performance of Band 9; for this a straw-man design of an OMT-based architecture (rather than the current grid-based design) was presented. In the currently running follow-up study ``Towards a Producible ALMA2030-Ready Band 9 CCA'' (also co-funded by ESO, with Observatorio Astron\'omico de Yebes and Chalmers University as partners), we address the lessons learned in the former study with the goal of arriving at a reviewable 2SB Band 9 WSU-compliant receiver prototype with polarimetric performance (cross-polar and beam squint) on par with the other OMT-based ALMA bands. We present the up-to-date results of this study (started Oct 2024).

description: The massive Wolf-Rayet type star WR 102c is located near the Quintuplet Cluster - one of the three massive star clusters in the Galactic Center region. Previous studies indicated that WR 102c may have a dusty circumstellar nebula and is among the main ionizing sources of the Sickle Nebula associated with the Quintuplet cluster. We obtained observations with the ESO's VLT integral field spectrograph SINFONI in the K-band, extracted the stellar spectra, and analyzed them by means of stellar atmosphere models. Our new analysis supersedes the results reported for WR 102c previously. We significantly revise down its bolometric luminosity and hydrogen content. We detect four early OB type stars close to WR 102c. These stars have radial velocities similar to that of WR 102c. We suggest that together with WR 102c these stars belong to a distinct star cluster with a total mass of about 1000 M_sun. We identify a new WR nebula around WR 102c in the SINFONI map of the diffuse Br$γ$ emission and in the HST's Pa$α$ images. The Br$γ$ line at different locations is not significantly broadened and similar to the width of nebular emission elsewhere in the H II region around WR 102c. The massive star WR 102c located in the Galactic Center region resides in a star cluster containing further early type stars. The stellar parameters of WR 102c are typical for hydrogen-free WN6 stars. We newly identify a nebula surrounding WR 102c that has a morphology similar to other nebulae around hydrogen-free WR stars, and propose that the formation of this nebula is linked to interaction of the fast stellar wind with the matter ejected at previous evolutionary stage of WR 102c.

title: Effects of fish oil-derived N-3 polyunsaturated fatty acids on the generation and functional activities of extracellular vesicles
Creators: name: Zhou, Ruihan

description: Background: Extracellular vesicles (EVs) are submicron membrane-bound vesicles released from almost all cells, which affect many pathophysiological processes involved in cardiovascular diseases (CVDs) and may therefore be considered as a novel marker for CVDs. N-3 polyunsaturated fatty acids (n-3 PUFA) have been suggested to play a role in protecting cardiovascular health. However, there is little information about the effect of n-3 PUFA on circulating EV numbers, composition and functional activity in the context of CVDs. Objective: This project investigated the relationships between circulating EVs, cardiovascular risk markers and CVD risk, as well as the chronic effects of fish oil�derived n-3 PUFA on the numbers, fatty acid composition and procogulatory activity of circulating EVs. Design: Subjects (n=40) aged 40-70yrs with moderate risk of CVDs were recruited into a double-blind, randomised crossover trial of fish oil (1.8g/d n-3 PUFA) or control oil (high-oleic safflower oil) for 12 weeks with a 12-week washout. EVs were analysed by Nanoparticle Tracking Analysis (NTA) and fluorescence flow cytometry (FCM). Total lipid fatty acid composition and procoagulatory activity of circulating EVs were analysed by gas chromatography and a thrombin generation assay, respectively. Results: Circulating EV numbers were positively associated with body mass index (BMI), blood pressure (BP), plasma triacylglycerol (TAG) concentration and overall CVD risk. Furthermore, plasma TAG concentration and diastolic blood pressure (DBP) independently predicted total EV numbers based on a multivariate regression model. Fish oil supplementation significantly decreased numbers of circulating EVs, modified their total lipid fatty acid composition and decreased their thrombogenic potential. Conclusion: Circulating EVs are associated with CVD risk and are particularly strongly related with plasma TAG concentration and DBP. They could therefore potentially serve as a novel biomarker for CVD prediction. Dietary n-3 PUFA modifies the numbers, fatty acid composition and function of circulating EVs in a manner which suggests beneficial effects of n-3 PUFA on CVDs.

description: Relativistic jets launched by supermassive black holes in the centers of active galaxies are some of the most energetic phenomena in the Universe. These jets shine brightly over the entire electromagnetic spectrum and are capable of accelerating particles to extreme energies. Although the exact jet launching mechanism is not yet understood, it is believed that magnetic fields anchored to the black hole or the accretion disk extract energy from the rotating system, launching relativistic bipolar outflows.  One way to study the magnetic field structure in these jets is via modeling their linear polarization as a function of wavelength, which provides, for example, the Faraday rotation measure that is related to the line-of-sight magnetic field strength in the rotating medium. To probe the regions relevant for jet launching, one needs to observe at high millimeter wavelengths where the jets are fully opaque unlike in the centimeter wavelengths where synchrotron self-absorption is prominent. In 2016 we observed the archetypal quasar 3C273 in full polarization with ALMA at band 6 and detected a very high Faraday rotation measure of 5 $\times$ 10$^5$ rad/m$^2$ over the available instantaneous bandwidth. In our follow-up observations in 2018 the rotation measure is much lower and it cannot be detected over band 6 alone. In my talk, I will discuss the improvements expected in the modeling of the polarization of relativistic jets by the increase in the instantaneous bandwidth offered by the WSU.

description: Ausgehend von der Frage nach einer wachstumsneutralen Sozialen Sicherung im Sinne der Postwachstumsbewegung untersucht die vorliegende Arbeit anhand einer kleinen empirischen Studie die Alterssicherung der Kommune Niederkaufungen. Diese fußt neben dem herkömmlichen Sicherungssystem unserer Gesellschaft auf weiteren sicherheitsstiftenden Elementen wie einer gemeinsamen Ökonomie, kollektivem Arbeiten, verlässlichen Beziehungen, egalitären Strukturen und einer übergeordneten Werteorientierung. Mit Hilfe klassischer wirtschaftsethnologischer Modelle von Gabe, Austausch, Teilen, Reziprozität und Redistribution [nach Mauss und Sahlins] werden vorgefundene Dynamiken der Kommune ethnographisch beschrieben. Dabei stellt sich der Gabentausch als ein Grundprinzip der sozialökologischen Konsensgemeinschaft heraus.Die Alterssicherung sowie das gesamte Ordnungssystem der intentionalen Gemeinschaft beruht auf permanenten und konfliktreichen Aushandlungen, die durch Prozesse des Gebens und Nehmens gestaltet sind.Selbstorganisation auf Basis von Solidarität als ein Grundprinzip der kommunitären Sicherung ist sowohl als Ergänzung eines auf Verträgen basierenden Sicherungssystems diskussionswürdig, als auch als ein Baustein für wachstumsneutrale Gesellschafts- und Sicherungskonzepte.
description: Starting from the issue of growth-neutral social security as postulated by the degrowth movement this bachelor thesis explores the old-age provision of the commune Niederkaufungen. Apart from the common security system this specific old-age provision relies on elements like common economy, collective work, dependable relationships, egalitarian structures and strong value orientation.By means of classical concepts of economic anthropology such as gift, exchange, sharing,reciprocity and redistribution (particularly based on Mauss and Sahlins) the thesis describes ethnographically dynamics that have been found in the commune. It is shown that the gift exchange is a fundamental principle of this consensus-based community.The old-age provision, as well as the communitarian arrangement system as a whole, bases on permanent and often conflictual negotiations that are shaped by processes of giving and taking. Solidarity-based self-organization is worth to be discussed both as an addition to the common contract-based security system and as an element of degrowth-orientated security systems.

description: A scanning white light interferometer is developed to measure the distributed polarization coupling (DPC) in high birefringence polarization maintaining fibers (PMFs). Traditionally, this technique requests only one polarization mode to be excited or both polarization modes to be excited with equal intensity in the PMF. Thus, an accurate alignment of the polarization direction with the principal axis in PMF is strictly required, which is not facilely realized in practical measurement. This paper develops a method to measure the spatial distribution of polarization mode coupling with random modes excited using a white light Michelson interferometer. The influence of incident polarization extinction ratio (PER) on polarization coupling detection is evaluated theoretically and experimentally. It is also analyzed and validated in corresponding measurement that the sensitivity of the polarization coupling detection system can be improved more than 100 times with the rotation of the analyzer.
