Scrutinizing the Cosmological Constant Problem and a possible resolution

description: We suggest a new perspective on the Cosmological Constant Problem by scrutinizing its standard formulation. In classical and quantum mechanics without gravity, there is no definition of the zero point of energy. Furthermore, the Casimir effect only measures how the vacuum energy {\it changes} as one varies a geometric modulus. This leads us to propose that the physical vacuum energy in a Friedman-Lemaître-Robertson-Walker expanding universe only depends on the time variation of the scale factor $a(t)$. Equivalently, requiring that empty Minkowski space is gravitationally stable is a principle that fixes the ambiguity in the zero point energy. On the other hand, if there is a meaningful bare cosmological constant, this prescription should be viewed as a fine-tuning. We describe two different choices of vacuum, one of which is consistent with the current universe consisting only of matter and vacuum energy. The resulting vacuum energy density $\rhovac$ is constant in time and approximately $k_c^2 H_0^2$, where $k_c$ is a momentum cut-off and $H_0$ is the current Hubble constant; for a cut-off close to the Planck scale, values of $\rhovac$ in agreement with astrophysical measurements are obtained. Another choice of vacuum is more relevant to the early universe consisting of only radiation and vacuum energy, and we suggest it as a possible model of inflation.

description: We identify three dimeric proteins whose mechanostability is anisotropic and should exceed 1 nN along some directions. They come with distinct mechanical clamps: shear-based, involving a cystine slipknot, and due to dragging of a cystine plug through a cystine ring. The latter two mechanisms are topological in nature and the cystine plug mechanism has not yet been discussed but it turns out to provide the largest resistance to stretching. Its possible applications in elastomers are discussed.

description: Das hier vorgestellte gemeinsame DSpace Metadatenmodell der Einrichtungen der Berlin University Alliance (Charité - Universitätsmedizin Berlin, Freie Universität Berlin, Humboldt-Universität zu Berlin, Technische Universität Berlin) orientiert sich an den aus der langjährigen Praxis notwendig gewordenen und regelmäßig verwendeten Metadaten. Es enthält jeweils einheitliche Benennungen der Metadaten, Beschreibungen und Beispiele. Dabei wurde sowohl auf die in DSpace bereits enthaltenen Dublin Core - Standards zurückgegriffen als auch auf die Option, diese in DSpace zu erweitern bzw. ergänzend zu definieren. Ziel dieser Initiative ist es, ein gemeinsames Metadatenschema zu entwickeln, das in den DSpace Repositorien aller Berliner Universitäten verwendet werden soll. Gleichzeitig wird es bei Einführung des neuen Modells möglich sein, Mappingtabellen, Schnittstellen und Programmierarbeiten zwischen den beteiligten Einrichtungen leichter auszutauschen und somit eine Nachnutzbarkeit effizient zu gewährleisten. Im Datenmodell werden drei Schemas als namespace-IDs benutzt: dc, dcterms und bua. Nicht in der Tabelle enthalten sind die lokalen Felder, die institutionsspezifisch genutzt werden und eigene namespaces verwenden: tub, edocs und refubium. Institutionelle Unterschiede hinsichtlich Reporting, Workflows und technischen Umgebungen machen es notwendig, derartige Felder zu unterstützen. Die Präsentation in einer Excel-Datei soll Nachnutzenden den Gebrauch erleichtern.
The Acceleration of Electrons at Perpendicular Shocks and its Implication for Solar Energetic Particle events

description: We present a study of the acceleration of electrons at a perpendicular shock that propagates through a turbulent magnetic field. The energization process of electrons is investigated by utilizing a combination of hybrid (kinetic ions and fluid electron) simulations and test-particle electron simulations. In this method, the motions of the test-particle electrons are numerically integrated in the time-dependent electric and magnetic fields generated by two-dimensional hybrid simulations. We show that large-scale magnetic fluctuations effect electrons in a number of ways and lead to efficient and rapid energization at the shock front. Since the electrons mainly follow along magnetic lines of force, the large-scale braiding of field lines in space allows the fast-moving electrons to interact with the shock front and get accelerated multiple times. Ripples in the shock front occurring at various scales will also contribute to the acceleration by mirroring the electrons. Our calculation shows that this process favors electron acceleration at perpendicular shocks. The acceleration efficiency is critically dependent on the turbulence amplitude and coherence length. We also discuss the implication of this study for solar energetic particles (SEPs) by comparing the acceleration of electrons with that of protons. Their correlation indicates that perpendicular shocks play an important role in SEP events.

description: We reanalyse Majorana-neutrino mass matrices M_nu with two texture zeros, by searching for viable hybrid textures in which the non-zero matrix elements of M_nu have simple ratios. Referring to the classification scheme of Frampton, Glashow and Marfatia, we find that the mass matrix denoted by A1 allows the ratios (M_nu)_{mu mu} : (Mnu)_{tau tau} = 1:1 and (M_nu)_{e tau} : (Mnu)_{mu tau} = 1:2. There are analogous ratios for texture A2. With these two hybrid textures, one obtains, for instance, good agreement with the data if one computes the three mixing angles in terms of the experimentally determined mass-squared differences Delta m^2_21 and Delta m^2_31. We could not find viable hybrid textures based on mass matrices different from those of cases A1 and A2.

description: We calculate the maximal absorption enhancement obtainable by guided mode excitation in a weakly absorbing dielectric slab over wide wavelength ranges. The slab mimics thin film silicon solar cells in the low absorption regime. We consider simultaneously wavelength-scale periodicity of the texture, small thickness of the film, modal properties of the guided waves and their confinement to the film. Also we investigate the effect of the incident angle on the absorption enhancement. Our calculations provide tighter bounds for the absorption enhancement but still significant improvement is possible. Our explanation of the absorption enhancement can help better exploitation of the guided modes in thin film devices.

description: We perform no-core configuration interaction calculations for nuclei in the p-shell. We show that for typical light nuclei, a truncation on the total number of quanta in the many-body system converges much more rapidly than a full configuration interaction (FCI) truncation, which is a truncation on the single-particle basis space. We present new results for the ground state energies of the Be isotopes with the nonlocal two-body potential JISP16, and discuss emerging phenomena such as clustering and rotational band structures in 9Be. We also show that the anomalously suppressed beta decay of 14C to the ground state of 14N can be reproduced using two- and three-nucleon forces from chiral effective field theory. In particular the structure of the ground state of 14N is sensitive to the three-nucleon force.

description: We develop and analyze a theoretical model which yields the shifts and widths of Feshbach resonances in an atomic waveguide. It is based on a multichannel approach for confinement-induced resonances (CIRs) and atomic transitions in the waveguides in the multimode regime. We replace in this scheme the single-channel scalar interatomic interaction by the four-channel tensorial potential modeling resonances of broad, narrow and overlapping character according to the two-channel parametrization of A.D.Lange et al. As an input the experimentally known parameters of Feshbach resonances in the absence of the waveguide are used. We calculate the shifts and widths of s-, d- and g-wave magnetic Feshbach resonances of Cs atoms emerging in harmonic waveguides as CIRs and resonant enhancement of the transmission at zeros of the free space scattering length. We have found the linear dependence of the width of the resonance on the longitudinal atomic momentum and quadratic dependence on the waiveguide width. Our model opens novel possibilities for quantitative studies of the scattering processes in ultracold atomic gases in waveguides beyond the framework of s-wave resonant scattering.

description: We present a multi-wavelength study of the emission-line nebulae located southeast of the nucleus of M87, the central dominant galaxy of the Virgo Cluster. We report the detection of far-infrared (FIR) [CII] line emission from the nebulae using observations made with Herschel PACS. The infrared line emission is extended and cospatial with optical Hα+[NII], far-ultraviolet CIV lines, and soft X-ray emission. The filamentary nebulae evidently contain multi-phase material spanning a temperature range of at least 5 orders of magnitude, from ~100 K to ~10^7 K. This material has most likely been uplifted by the AGN from the center of M87. The thermal pressure of the 10^4 K phase appears to be significantly lower than that of the surrounding hot intra-cluster medium (ICM) indicating the presence of additional turbulent and magnetic pressure in the filaments. If the turbulence in the filaments is subsonic then the magnetic field strength required to balance the pressure of the surrounding ICM is B~30-70 μG. The spectral properties of the soft X-ray emission from the filaments indicate that it is due to thermal plasma with kT~0.5-1 keV, which is cooling by mixing with the cold gas and/or radiatively. Charge exchange can be ruled out as a significant source of soft X-rays. Both cooling and mixing scenarios predict gas with a range of temperatures. This is at first glance inconsistent with the apparent lack of X-ray emitting gas with kT<0.5 keV. However, we show that the missing very soft X-ray emission could be absorbed by the cold gas in the filaments with an integrated hydrogen column density of ~1.6x10^21 cm^-2, providing a natural explanation for the apparent temperature floor to the X-ray emission at kT~0.5 keV. The FIR through ultra-violet line emission is most likely primarily powered by the ICM particles penetrating the cold gas following a shearing induced mixing process.

description: This article summarizes our understanding of the Kondo effect in graphene, primarily from a theoretical perspective. We shall describe different ways to create magnetic moments in graphene, either by adatom deposition or via defects. For dilute moments, the theoretical description is in terms of effective Anderson or Kondo impurity models coupled to graphene's Dirac electrons. We shall discuss in detail the physics of these models, including their quantum phase transitions and the effect of carrier doping, and confront this with existing experimental data. Finally, we point out connections to other quantum impurity problems, e.g., in unconventional superconductors, topological insulators, and quantum spin liquids.

description: The objective of this study is to simulate a payment for environmental services scheme to reduce enteric methane emissions per litre of milk by incentivizing farmers to modify the diet of dairy cows. We estimated a milk yield function by distinguishing between types of fodder and concentrate feeds. Methane emissions were calculated from the technical relationship between different feed sources and milk productivity. The heterogeneity of the production conditions faced by the farmers was identified from a mixture model estimated by the EM algorithm. The results show that, with the introduction of the payment for environmental services, farmers reduce their methane emissions per litre of milk the more their production conditions, as reflected by the quality of their forage, are good.

description: We investigate the charge re-distribution upon optical excitation of various necked homodimer CQDMs using single particle emission spectroscopy. By tuning the hybridization of the electron wavefunction at a fixed center-to-center distance through controlling the neck girth, we reveal two coupling limits. On one hand a connected-but-confined situation where neighbouring CQDs are weakly fused to each other manifesting a weak coupling regime, and on the other hand, a connected-and-delocalized situation, where the neck is filled beyond the facet size leading to a rod-like architecture manifesting strong-coupling. Either coupling regimes entrust distinct optical signatures clearly resolved at room temperature in terms of photoluminescence quantum yield, intensity time traces, lifetimes, and spectra of the neutral-exciton, charged-exciton, and biexciton states. The interplay between the radiative and non-radiative Auger decays of these states, turns emitted photons from the CQDMs in the weak-coupling regime highly bunched unlike CQD monomers, while the antibunching is regained at the strong-coupling regime. This behavior correlates with the hybridization energy being smaller than the thermal energy (kT approx. 25meV) at the weak-coupling limit (delta E approax.5-10meV), leading to exciton localization suppressing Auger decay. In the neck-filled architectures, the larger hybridization energy (delta E approx.20-30meV) leads to exciton delocalization while activating the fast charged and multi-exciton Auger decay processes. This work sets an analogy for the artificial molecule CQDMs with regular molecules, where the two distinct regimes of weak- and strong-coupling correspond to ionic- or covalent- type bonding, respectively.

description: In this work we investigate whether it is plausible to use the performance of a reinforcement learning (RL) agent to estimate the difficulty measured as the player completion rate of different levels in the mobile puzzle game Lily's Garden.For this purpose we train an RL agent and measure the number of moves required to complete a level. This is then compared to the level completion rate of a large sample of real players.We find that the strongest predictor of player completion rate for a level is the number of moves taken to complete a level of the ~5% best runs of the agent on a given level. A very interesting observation is that, while in absolute terms, the agent is unable to reach human-level performance across all levels, the differences in terms of behaviour between levels are highly correlated to the differences in human behaviour. Thus, despite performing sub-par, it is still possible to use the performance of the agent to estimate, and perhaps further model, player metrics.

description: Doped heavy metal-free III-V semiconductor nanocrystal quantum dots are of great interest both from the fundamental aspects of doping in highly confined structures, and from the applicative side of utilizing such building blocks in the fabrication of p-n homojunction devices. InAs nanocrystals, that are of particular relevance for short wave IR detection and emission applications, manifest heavy n-type character poising a challenge for their transition to p-type behavior. We present p-type doping of InAs nanocrystals with Zn-enabling control over the charge carrier type in InAs QDs field effect transistors. The post-synthesis doping reaction mechanism is studied for Zn precursors with varying reactivity. Successful p-type doping was achieved by the more reactive precursor, diethylzinc. Substitutional doping by Zn2+ replacing In3+ is established by X-ray absorption spectroscopy analysis. Furthermore, enhanced near IR photoluminescence is observed due to surface passivation by Zn as indicated from elemental mapping utilizing high resolution electron microscopy corroborated by X-ray photoelectron spectroscopy study. The demonstrated ability to control the carrier type, along with the improved emission characteristics, paves the way towards fabrication of optoelectronic devices active in the short wave IR region utilizing heavy-metal free nanocrystal building blocks.

description: We study fermions in two dimensions interacting via a long-ranged 1/r potential for small particle separations and a short-ranged 1/r^3 potential for larger separations in comparison to a length scale ξ. We compute the energy of the Wigner crystal and of the homogeneous Fermi liquid phases using a variational approach, and determined the phase diagram as a function of density and ξat zero temperature. We discuss the collective modes in the Fermi liquid phase, finite temperature effects on the phase diagram, and possible experimental realizations of this model.

description: Background: Appreciative Inquiry (AI), is a well-researched and utilised strengths-based process that seeks the best of people and the organisations in which they work. AI has and can be used extensively in any area of education. The AI process is an inclusive one that encourages participation from all members to participate through its 4-D model (discover, dream, design and destiny).
 The presenter is an accredited Appreciative Inquiry facilitator who has led many leaders and educators through the process with positive outcomes and feedback because of the high-level of inclusivity. The strengths-based model has participants actively participating in the process from start to end with the focus on a common goal. The workshop will allow participants to take part in a 'mini' version of the process to experience how Appreciative Inquiry works and inspires all participants, enables a connected and collaborative process towards a common goal and it creates positivity through its positive approach.

 Structure of Workshop: The workshop will involve participants taking part in the “4-D” appreciative inquiry model by choosing their own relevant topic then breaking into pairs for the activities, then small group and whole group discussion and sharing. It is a fun and interactive workshop with key take-aways that can be implemented into daily work once participants are back in their own work environments.

 Intended Outcomes: Identify personal intention for session attendance (in contect of the workshop topic) Outline the AI model and relate process to work practices Participate in the four components of the AI model through discussion,, clarification, interpretation and translation Create and design strategies and a vision for enhancing leadership as a health educator

description: Monte Carlo methods are used to approximate the means, $μ$, of random variables $Y$, whose distributions are not known explicitly. The key idea is that the average of a random sample, $Y_1, ..., Y_n$, tends to $μ$ as $n$ tends to infinity. This article explores how one can reliably construct a confidence interval for $μ$ with a prescribed half-width (or error tolerance) $\varepsilon$. Our proposed two-stage algorithm assumes that the kurtosis of $Y$ does not exceed some user-specified bound. An initial independent and identically distributed (IID) sample is used to confidently estimate the variance of $Y$. A Berry-Esseen inequality then makes it possible to determine the size of the IID sample required to construct the desired confidence interval for $μ$. We discuss the important case where $Y=f(\vX)$ and $\vX$ is a random $d$-vector with probability density function $ρ$. In this case $μ$ can be interpreted as the integral $\int_{\reals^d} f(\vx) ρ(\vx) \dif \vx$, and the Monte Carlo method becomes a method for multidimensional cubature.

description: To improve the knowledge about physical exercise in patients with Hereditable Thoracic Aortic Disease, insight to the patient perspectives is necessary. The aim of this study was to explore aspects related to physical exercise as highlighted by the patients themselves. Focus group interviews with 36 people with Marfan syndrome, Loeys-Dietz syndrome and vascular Ehlers Danlos syndrome were conducted. Inductive systematic condensation analysis was performed. Four themes related to physical exercise were elucidated by the participants: (1) Being diagnosed. (2) Considerations of physical exercise. (3) Body image and function. (4) Future perspectives. The four themes are mutually interrelated in terms of barriers, facilitators and strategies for dealing with physical exercise. Our findings indicate that the participants experience exercise as a consistent dilemma between what is healthy and what is risky. Inconsistent professional advice, non-engaging activities, unpredictable health conditions and a fear of exercising were factors that may contribute to inactivity and a sedentary lifestyle. The complexity and existential internal conflict related to physical exercise seemed to be a huge dilemma among persons with Hereditable Thoracic Aortic Disease. The balance between safe and healthy activities should be a research priority in these groups.Implications for rehabilitationPhysical activity and exercise pose a difficult dilemma for patients with Hereditable Thoracic Aortic Disease, in terms of what is healthy and what is dangerous.People with Hereditable Thoracic Aortic Disease need help to minimize concern, stress and anxiety associated with exercise.Individualized adapted programs including physical, psychological and social rehabilitation goals are most likely to be successful in encouraging exercise in these patient groups.

description: Background: In Brazil, Medical School is a 6-year course, after which the recently-graduated physicians can start their practice. Along the medical course, Brazilian students are traditionally evaluated by theoretical knowledge-based assessments, resulting in a fragmented teaching and learning process that is no longer appropriate.
 Summary of Work: At our institution, we implemented sequential formative assessments based on the Objective Structured Clinical Examination (OSCE) for students in the last four years of the medical course (clinical cycle). We began with an examination blueprint including essential clinical competencies required for physicians: communication and interaction with the patient, history-taking, clinical examination, procedures, interpretation of findings, and decision-making. Planning took place from March to September, and the exams were held in October (5th and 6th years) and November (3rd and 4th years) of 2022.
 Summary of Results: We evaluated 133 students from the 3rd and 4th years (optional participation) and 210 students from the 5th and 6th years (mandatory participation) in eight sequential stations, including topics from major clinical areas. Stations were adjusted according to student level along the medical curriculum. Six replicas were created for each station. Within five minutes of completing the task, followed by one minute of feedback provided by a trained examiner, students were evaluated for their performance in each competency described in the blueprint. After the exam, each student received an individual performance report compared to other students at the same level. Students ranked in the lowest quartiles of the group in more than four competencies were invited for remediation. In anonymous questionnaires, the students considered the exam a necessary learning experience and an opportunity for self-assessment and planning of future studying strategies.
 Discussion and Conclusion: We have reached a significant milestone in evaluating the developmental progression of abilities from the whole clinical cycle. We intend to repeat the exam in the coming years as a method of longitudinal student assessment that we hope to incorporate into our teaching curriculum and expand to other Brazilian medical schools.
 Take home messages: This innovative Large-scale clinical skills assessment of students in our country is an initial step toward updating medical education in Brazil.

description: We are performing a transient, microsecond timescale radio sky survey, called "Astropulse," using the Arecibo telescope. Astropulse searches for brief (0.4 μs to 204.8 μs), wideband (relative to its 2.5 MHz bandwidth) radio pulses centered at 1,420 MHz. Astropulse is a commensal (piggyback) survey, and scans the sky between declinations of -1.33 and 38.03 degrees. We obtained 1,540 hours of data in each of 7 beams of the ALFA receiver, with 2 polarizations per beam. Examination of timescales on the order of a few microseconds is possible because we used coherent dedispersion. The more usual technique, incoherent dedispersion, cannot resolve signals below a minimum timescale. However, coherent dedispersion requires more intensive computation than incoherent dedispersion. The required processing power was provided by BOINC, the Berkeley Open Infrastructure for Network Computing.
