description: We present deep Near-infrared (NIR) images of a sample of 19 intermediate-redshift (0.310^27 WHz^-1), previously classified as flat-spectrum radio quasars. We also compile host galaxy and nuclear magnitudes for blazars from literature. The combined sample (this work and compilation) contains 100 radio-loud AGN with host galaxy detections and a broad range of radio luminosities L1.4GHz = 10^23.7 - 10^28.3WHz^-1, allowing us to divide our sample into high-excitation (quasar-mode; HERGs) and low-excitation (radio-mode; LERGs) radio galaxies. The host galaxies of our sample are bright and seem to follow the Kormendy relation. Nuclear emission (dominated by non-thermal mechanisms) and host-galaxy magnitudes show a slightly negative weak trend for LERGs. On the other hand, the m_bulge -m_nuc relation is statistically significant for HERGs. Although it may be affected by selection effects, this correlation suggests a close coupling between the relativistic jets and their host galaxy. Our findings are consistent with the excitation state (LERG/HERG) scenario. In this view, LERGs emit the bulk of their energy in the form of radio jets, producing a strong feedback mechanism, and HERGs are affected by galaxy mergers and interactions, which provide a common supply of cold gas to feed both nuclear activity and star formation episodes.
Investigating the Role of Vitamin D in Epithelial Differentiation of the Prostate
Creators: name: Krieger, Kirsten Dee
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This thesis presents the extensive impact of vitamin D on epithelial differentiation in the prostate. Utilizing three complementary models, mouse dorsolateral prostate organoids treated with vitamin D, analysis of prostates from mice with systemic vitamin D deficiency or sufficiency, and human prostate cancer cells adapted for 6 months to physiological levels of vitamin D, we demonstrate the influential role that vitamin D sufficiency plays in supporting epithelial differentiation thus benefiting healthy, benign prostatic differentiation. In the context of prostate disease, we observed substantial alterations in growth, cellular morphology, and gene expression supporting that vitamin D deficiency abrogates epithelial differentiation in prostate cancer cells thus enhancing disease aggressiveness. This work also demonstrates the complex interplay, or hormonal crosstalk, between vitamin D and androgen signaling in the prostate, extending previous findings from cell lines to three novel models and validating the importance that vitamin D plays in regulating prostatic epithelial differentiation. Overall, this thesis provides insight and validation of the beneficial, protective role of vitamin D in both benign and malignant prostate biology, highlighting the potential implications of vitamin D for therapeutic strategies, including vitamin D supplementation aimed at reducing PCa incidence and aggressiveness in at-risk populations. This thesis presents a putative relationship between the racial disparities observed in prostate cancer and vitamin D deficiency, thereby motivating future research to investigate potential mechanisms, surrounding vitamin D regulation of androgen-regulated genes, and public health implications.

description: Optical lattices are known for their flexibility to emulate condensed matter physics and beyond. Based on an early theoretical proposal [Science Bulletin 65, 2080 (2020)], a recent experiment published by Wang et al. [Science 372, 271 (2021)] accomplishes the first experimental realization of topological band structure of the ideal Weyl semimetal in ultracold atomic matter, prompting fundamental interest in the context of gapless topological physics. With a neat design of 3D spin-orbit interaction, the experiment has probed the gapless band topology through spin texture imaging and quantum quench dynamics. This work has far reaching implications to topological effects and quantum anomaly in condensed matter and high energy physics.

description: The vacuum expectation values (VEVs) of the field squared and energy-momentum tensor for a massless scalar field are investigated in the Milne universe with general number of spatial dimensions. The vacuum state depends on the choice of the mode functions in the canonical quantization procedure and we assume that the field is prepared in the conformal vacuum. As the first step an integral representation for the difference of the Wightman functions corresponding to the conformal and Minkowski vacua is derived. The mean field squared and energy-momentum tensor are obtained in the coincidence limit. It is shown that the Minkowski vacuum state is interpreted as a thermal one with respect to the conformal vacuum. The thermal factor is of the Bose-Einstein type in odd dimensional space and of the Fermi-Dirac type in even number of spatial dimensions.

description: In this Brief Report, we propose a new index of user similarity, namely the transferring similarity, which involves all high-order similarities between users. Accordingly, we design a modified collaborative filtering algorithm, which provides remarkably higher accurate predictions than the standard collaborative filtering. More interestingly, we find that the algorithmic performance will approach its optimal value when the parameter, contained in the definition of transferring similarity, gets close to its critical value, before which the series expansion of transferring similarity is convergent and after which it is divergent. Our study is complementary to the one reported in [E. A. Leicht, P. Holme, and M. E. J. Newman, Phys. Rev. E {\bf 73} 026120 (2006)], and is relevant to the missing link prediction problem.

Experimental and numerical analysis of a fishing vessel motions and stability in a longitudinal seaway
Creators: name: Allievi, Alejandro
Publisher: name: University of British Columbia
Year: 2010

description: Motions and stability of a typical B.C. fishing vessel were experimentally and numerically investigated in a longitudinal seaway condition. The experimental model was self-propelled, radio-controlled and equipped with an on-board data acquisition system. Pitch, roll, yaw, surge, and heave responses to regular waves of predetermined frequencies and amplitudes generated along a 220-ft model basin were obtained. Different displacement conditions and GM configurations were tested. The numerical model for the dynamic analysis of the fishing vessel motions has been implemented using strip theory. A computer program was developed to study the nonlinear motions of the vessel. The velocity dependent coupling terms, responsible for a major part of the nonlinear behavior, were included. A time dependent component analysis of the roll damping has been performed. Regular linear and nonlinear waves were used. A parametric study of the fishing vessel stability has been carried out by considering its dynamic response in waves of varying characteristics. Unstable behaviour was found to be closely related to waves of length of similar magnitude to the ship length. The effects of wave amplitude and rudder usage were found to be of capital importance in the capsizing process. Experimental and numerical results showed good agreement.

description: In the practical continuous-variable quantum key distribution (CV-QKD) system, the postprocessing process, particularly the error correction part, significantly impacts the system performance. Multi-edge type low-density parity-check (MET-LDPC) codes are suitable for CV-QKD systems because of their Shannon-limit-approaching performance at a low signal-to-noise ratio (SNR). However, the process of designing a low-rate MET-LDPC code with good performance is extremely complicated. Thus, we introduce Raptor-like LDPC (RL-LDPC) codes into the CV-QKD system, exhibiting both the rate compatible property of the Raptor code and capacity-approaching performance of MET-LDPC codes. Moreover, this technique can significantly reduce the cost of constructing a new matrix. We design the RL-LDPC matrix with a code rate of 0.02 and easily and effectively adjust this rate from 0.016 to 0.034. Simulation results show that we can achieve more than 98% reconciliation efficiency in a range of code rate variation using only one RL-LDPC code that can support high-speed decoding with an SNR less than -16.45 dB. This code allows the system to maintain a high key extraction rate under various SNRs, paving the way for practical applications of CV-QKD systems with different transmission distances.

description: A number of solar filaments/prominences demonstrate failed eruptions, when a filament at first suddenly starts to ascend and then decelerates and stops at some greater height in the corona. The mechanism of the termination of eruptions is not clear yet. One of the confining forces able to stop the eruption is the gravity force. Using a simple model of a partial current-carrying torus loop anchored to the photosphere and photospheric magnetic field measurements as the boundary condition for the potential magnetic field extrapolation into the corona, we estimated masses of 15 eruptive filaments. The values of the filament mass show rather wide distribution in the range of $4\times10^{15}$ -- $270\times10^{16}$g. Masses of the most of filaments, laying in the middle of the range, are in accordance with estimations made earlier on the basis of spectroscopic and white-light observations.

description: We describe the current status of CATS, a publicly accessible database (web-server http://cats.sao.ru) allowing one to search in hundreds of catalogs of astronomical objects discovered all along the electromagnetic spectrum. Our emphasis is mainly laid on catalogs of radio continuum sources observed from 30 to 15000 MHz, secondly on catalogs of objects such as radio and active stars, planetary nebulae, HII regions, supernova remnants (SNR), pulsars, nearby galaxies, AGN and quasars. CATS also includes the catalogs from the largest extragalactic surveys, like NVSS, FIRST, WENSS, VLSS, TXS, GB6, SUMSS, IRAS, 2MASS, SDSS, ROSAT, PGC, MCG, etc. In 2004 CATS comprised a total of $\sim10^9$ records from over 400 catalogs in the radio, IR, optical and X-ray windows, including most of RATAN--600 catalogs. CATS is being expanded and updated, both with newly published catalogs as well as older ones which we have created in electronic form for the first time. We describe the principles of organization of the database of astrophysical catalogs and the main functions of CATS.

"In college, I'm the one people go to": lessons from successful developmental literacy students about the transition to college-level courses across disciplines
Creators: name: Darkenwald-DeCola, Jessica A.
Publisher: name: No Publisher Supplied
Year: 2021

description: This study focused on the institutional issue of alignment between developmental literacy courses and college-level coursework. Research suggests alignment between these courses is a key condition for successful transfer of learning (Grubb, 2013; Grubb & Cox, 2005; Roueche & Roueche, 1999; Tinberg, 2015). This collective case study aimed to understand the ways in which community college students who initially placed well below the cutoff score for college level English, but successfully passed developmental literacy coursework, experienced the alignment between their developmental literacy and college-level coursework. This study was conducted at a community college in New Jersey. Participants were interviewed during and after the semester following their developmental literacy course. In these interviews, they described the strengths and challenges they experienced meeting the literacy demands and expectations of college-level courses in disciplines other than English. In addition, disciplinary faculty completed a survey about the reading and writing they assigned in their courses and course documents were collected. Data was analyzed through the lens of Lea and Street’s (1998/2006) academic literacies approach and Ivanic’s (2004) discourses for writing framework. Findings suggest that participants were able to apply many reading and writing strategies learned in their developmental literacy courses to the reading and writing they did in college-level courses across disciplines. In addition, participants reported affective benefits from their developmental literacy course, such as increased confidence and motivation, that positively impacted their performance in college-level courses. Participants also reported important differences between the two courses and some challenges related to both meeting the disciplinary literacy expectations in their college-level courses and transitioning between a developmental literacy course to a discipline-specific college-level course.The results of this study provide insight into what conditions and instructional approaches increase the likelihood of student success and learning transfer across contexts and have implications for both developmental literacy and disciplinary college-level educators. Implications for future research are also addressed.

description: We study the trapping of a ground-state cesium atom in a small region around the midpoint between two coupled identical parallel optical nanofibers. We suggest to use a blue-detuned guided light field in the odd $\mathcal{E}_z$-sine array mode to produce an optical potential with a local minimum of exact zero at the midpoint between the nanofibers. We find that the effects of the van der Waals potential on the total trapping potential around the minimum point are not significant when the fiber separation distance and the power of the guided light field are large. For appropriate realistic parameters, a net trapping potential with a significant depth of about 1 mK, a large coherence time of several seconds, and a large recoil-heating-limited trap lifetime of several hours can be obtained. We investigate the dependencies of the trapping potential on the power of the guided light field, the fiber radius, the wavelength of light, and the fiber separation distance.

description: We analyze quantum fluctuation effects at the onset of charge or spin density wave order in two-dimensional metals with an incommensurate nesting ($2k_F$) wave vector connecting two pairs of hot spots on the Fermi surface. We first compute the momentum and frequency dependence of the fermion self-energy near the hot spots to leading order in a perturbation expansion (one loop). Non-Fermi liquid behavior with a linear (in energy) quasi-particle decay rate and a logarithmically vanishing quasi-particle weight is obtained. The momentum dependence of the self-energy entails only finite renormalizations of the Fermi velocity and the Fermi surface curvature at the hot spots. The perturbative one-loop result is not self-consistent and casts doubt on the stability of the $2k_F$ quantum critical point. We construct a self-consistent solution of the one-loop equations with self-energy feedback, where the quantum critical point is stabilized rather than being destroyed by fluctuations, while the non-Fermi liquid behavior as found in the perturbative one-loop calculation is confirmed.

description: For a multipartite correlation experiment with an arbitrary number of settings and any spectral type of outcomes at each site, we introduce a single general representation incorporating in a unique manner all Bell-type inequalities for either correlation functions or joint probabilities that have been introduced or will be introduced in the literature. Specifying this general representation for correlation functions, we prove that the form of any correlation Bell-type inequality does not depend on a spectral type of observed outcomes, in particular, on their numbers at different sites, and is determined only by extremal values of outcomes at each site. We also specify the general form of bounds in Bell-type inequalities on joint probabilities. Our approach to the derivation of Bell-type inequalities is universal, concise and can be applied to a multipartite correlation experiment with outcomes of any spectral type, discrete or continuous. We, in particular, prove that, for an N-partite quantum state, possibly, infinite dimensional, admitting the 2x...x2-setting LHV description, the Mermin-Klyshko inequality holds for any two bounded quantum observables per site, not necessarily dichotomic.

description: We consider models of inflection point inflation. The main drawback of such models is that they suffer from the overshoot problem. Namely the initial condition should be fine tuned to be near the inflection point for the universe to inflate. We show that stringy realizations of inflection point inflation are common and offer a natural resolution to the overshoot problem.

description: The aim of this paper is to unveil the main cultural patterns adopted by the Chinese leadership to

project smart power abroad, and to provide a new perspective on the claims by Chinese scholars and

politicians who argue that a new paradigm in international relations is being promoted by Beijing.

Principles as “inclusiveness”, “win-win cooperation”, “peaceful rise”, “harmonious world” – often raised

in relation with China’s vision for a new global order and its flagship policy, the Belt and Road Initiative

(BRI) – are part of a new narrative which cannot replace, for instance, fundamental issues as a clear

regulatory framework needed for enterprises willing to participate in BRI-related infrastructural and

energy projects. The lack of a clear legal framework is at the moment one of the most important problem

hindering foreign firms’ ability to invest and grow within the China-led initiative. The importance

of this study rests on the necessity to find new interpretative insights to understand the main driving

forces behind China's foreign policy (often not complying with Western-set rules and practices) by assessing

the role of Chinese classical culture in the projection of China's smart power. The main cultural

patterns and perspectives guiding Chinese policies abroad; the possibility that the Chinese government

is introducing a narrative shift in global policy practices; the surfacing of a possible new way for

international relations consistently based on an effort to improve international relations and enhance

the state of world affairs, or maybe simply of a strategic scheme meant to avoid creating a clearer

framework which could guarantee access to the initiative to all interested parts, at the same time limiting

Beijing's power to arbitrarily choose partners and directions, will all be objects of reflection.

description: Governments' net zero emission target aims at increasing the share of renewable energy sources as well as influencing the behaviours of consumers to support the cost-effective balancing of energy supply and demand. These will be achieved by the advanced information and control infrastructures of smart grids which allow the interoperability among various stakeholders. Under this circumstance, increasing number of consumers produce, store, and consume energy, giving them a new role of prosumers. The integration of prosumers and accommodation of incurred bidirectional flows of energy and information rely on two key factors: flexible structures of energy markets and intelligent operations of power systems. The blockchain and artificial intelligence (AI) are innovative technologies to fulfil these two factors, by which the blockchain provides decentralised trading platforms for energy markets and the AI supports the optimal operational control of power systems. This paper attempts to address how to incorporate the blockchain and AI in the smart grids for facilitating prosumers to participate in energy markets. To achieve this objective, first, this paper reviews how policy designs price carbon emissions caused by the fossil-fuel based generation so as to facilitate the integration of prosumers with renewable energy sources. Second, the potential structures of energy markets with the support of the blockchain technologies are discussed. Last, how to apply the AI for enhancing the state monitoring and decision making during the operations of power systems is introduced.

We show that if Q is a rooted tree (an oriented tree with a unique sink), then the ring $R(Q)_{red}$ is a finitely generated $\Z$-module (here $R(Q)_{red}$ is the ring R(Q) modulo the ideal of all nilpotent elements). We will describe the ring $R(Q)_{red}$ explicitly, by studying functors from the category Rep(Q) of representations of Q over K to the category of finite dimensional K-vector spaces. We also present an open problem for future direction.

description: The effects of interpreting classical phase space distributions as Wigner functions, which is common in models of multiparticle production, are discussed. The temperature for the classical description is always higher than that for its Wigner function interpretation. A rough estimate shows that the corresponding correction is proportional to R^(-2), where R is the radius of the interaction region, and that it is negligible for heavy ion scattering, but at the few percent level for e^+e^- annihilations.

Does Interaction Improve Bayesian Reasoning with Visualization?

description: Interaction enables users to navigate large amounts of data effectively, supports cognitive processing, and increases data representation methods. However, there have been few attempts to empirically demonstrate whether adding interaction to a static visualization improves its function beyond popular beliefs. In this paper, we address this gap. We use a classic Bayesian reasoning task as a testbed for evaluating whether allowing users to interact with a static visualization can improve their reasoning. Through two crowdsourced studies, we show that adding interaction to a static Bayesian reasoning visualization does not improve participants' accuracy on a Bayesian reasoning task. In some cases, it can significantly detract from it. Moreover, we demonstrate that underlying visualization design modulates performance and that people with high versus low spatial ability respond differently to different interaction techniques and underlying base visualizations. Our work suggests that interaction is not as unambiguously good as we often believe; a well designed static visualization can be as, if not more, effective than an interactive one.

description: Following the recent trend we develop further the black hole analogy between quantum information theory and the theory of extremal stringy black hole solutions. We show that the three-qubit interpretation of supersymmetric black hole solutions in the STU model can be extended also to include non-supersymmetric ones. First we show that the black hole potential can be expressed as one half the norm of a suitably chosen three-qubit entangled state containing the quantized charges and the moduli. The extremization of the black hole potential in terms of this entangled state amounts to either supressing bit flip errors (BPS-case) or allowing very special types of flips transforming the states between different classes of non-BPS solutions. We are illustrating our results for the example of the D2-D6 system. In this case the bit flip errors are corresponding to sign flip errors of the charges originating from the number of D2 branes. After moduli stabilization the states depending entirely on the charges are maximally entangled graph states (of the triangle graph) well-known from quantum information theory. An N=8 interpretation of the STU-model in terms of a mixed state with fermionic purifications is also given.

Development of Electrochemical Cyclization Reactions of Aryl Azides and Synthesis of NAMPT Activators

description: High throughput screening (HTS) identified NAMPT positive allosteric modulators (N-PAMS) whose binding with NAMPT was confirmed through a cocrystal structure. Analogs of the initial hit N-PAMs were synthesized to increase NAMPT activity in human THP-1 monocyte cells. Promising analogs were evaluated in neuronal HT-22 mouse hippocampal cell line subjected to inflammatory stress using tumor necrosis factor alpha (TNFα) to determine their effectiveness in reducing reactive oxygen species. These screens revealed an N-PAM that completely reduced ROS elevation in THFα glutamate-stressed HT-22 cells, a model of neuronal excitotoxicity. A study into the amination of C–H bonds through electrochemical oxidation was performed to access N-aryl nitrenoid formation from aryl amines. Anodic oxidation provides the potential to access reactive intermediates without chemical oxidant. Reaction conditions were screened using an undivided cell in an IKA electrasyn 2.0. Anodic oxidation of aryl amines to afford 3H-indoles proved to be a success. The reaction conditions were broad and tolerated electronic and steric changes. Further examination into diastereoselectivity indicated that electronic changes to π-π interactions play a role in diastereoselectivity of the reaction. Access to 3H-indoles was pursued through anodic oxidation of aryl azides was additionally investigated. Optimization of the electrochemical conditions provided a great conversion of aryl azide to 3H-indoles. This work provides the basis for future studies into the scope and mechanism of this reaction.

description: From photometric observations of elliptical galaxies, among which are both radio galaxies and radio-quiet objects, an investigation was carried out of the relationship `redshift -- age of the stellar system' $(Δz/Δt)$. By means of this relationship cosmological parameters $H(z)$ and $Ω_Λ$ are estimated. Ages of stellar systems are determined within the framework of evolution models of synthetic spectra PEGASE and GISSEL. This approach can be considered as time study of objects of the early Universe independent of other cosmological models. Construction of a pooled sample is described, containing 220 objects from different populations of elliptical galaxies, for which an analysis of the upper limit of the age of formation of a stellar system was performed. These data were used to estimate the boundaries of determination of the cosmological parameters $H_0$ and $Λ$--term: $H_0=72\pm10$ and $Ω_Λ=0.8\pm0.1$ in the model GISSEL and $H_0=53\pm10$, and $Ω_Λ=0.8\pm0.1$ in the model PEGASE.

description: These are the slides and results from a workshop "Plan S implementation by institutions and libraries" we did at OAI11 – The CERN-UNIGE Workshop on Innovations in Scholarly Communication in Geneva, June 19th, 2019.

The workshop description:

Plan S aims to accelerate the transition to open access by imposing stricter open access rules on funded researchers. This has an effect on many actors, including institutions and their libraries. They will have to think about if and how to support Plan S, how to achieve transformative agreements, how to advise researchers, and more.

This workshop is intended to bring together ideas and opinions on how institutions and libraries could and should relate to Plan S. Using the information available on possible concrete ways for researchers to achieve compliance for their publications (many of which are already exist and are proven in practice), what are the roles and responsibilities for institutions to support them in that? How do we make sure that the goal of Plan S is achieved while ensuring a diverse and sustainable open access landscape?

After getting an overview of Plan S and after hearing the participants’ perspectives on Plan S, the group will explore known problems and approaches. We will also look at the points raised in (public) input provided by institutions during the consultation around Plan S, and discuss how the position of institutions is influenced by their national contexts, the disciplines they serve and other factors.

Topics to be discussed can range from:

	considering institutional policies (will institutions decide to implement mandates in line with plan S?)
	negotiations with publishers towards transformative agreements and also publishing agreements with full OA publishers
	considering investing in common infrastructure, such as disciplinary repositories and OA publishing platforms
	developing institutional OA publication platforms
	making institutional repositories plan S compliant
	informing and supporting their researchers

At the end of the workshop, we will have an overview of possible actions and choices on the topics above, with some criteria that institutions can apply to their Plan S implementation processes.

While this workshop focuses on the implications of plan S for institutions (and their libraries), participation is not limited to representatives from institutions/libraries - other actors are welcome to contribute to this discussion from their perspective.

description: Accreting X-ray pulsars provide us with laboratories for the study of extreme gravitational and magnetic fields, hence accurate descriptions of their observational properties contribute to our understanding of this group of objects. We aim to detect a cyclotron resonance scattering feature in the Be/X-ray binary Cep X-4 and to investigate pulse profile and spectral changes through the outburst. Spectral fitting and timing analysis are employed to probe the properties of Cep X-4 during an outburst in 2002 June. A previously announced cyclotron feature at 30.7 keV is confirmed, while the source shows spectral behaviour and luminosity related changes similar to those observed in previous outbursts. The long-term X-ray lightcurve shows a periodicity at 20.85 d, which could be attributed to the orbit in this Be system.

The targum (1949:Feb. 1 - 1949:Feb. 25)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1949

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We have developed a technique utilizing a double quantum well heterostructure that allows us to study the effect of a nearby ground-plane on the metallic behavior in a GaAs two-dimensional hole system (2DHS) in a single sample and measurement cool-down, thereby maintaining a constant disorder potential. In contrast to recent measurements of the effect of ground-plane screening of the long-range Coulomb interaction in the insulating regime, we find surprisingly little effect on the metallic behavior when we change the distance between the 2DHS and the nearby ground-plane.

description: Maintaining computational load balance is important to the performant behavior of codes which operate under a distributed computing model. This is especially true for GPU architectures, which can suffer from memory oversubscription if improperly load balanced. We present enhancements to traditional load balancing approaches and explicitly target GPU architectures, exploring the resulting performance. A key component of our enhancements is the introduction of several GPU-amenable strategies for assessing compute work. These strategies are implemented and benchmarked to find the most optimal data collection methodology for in-situ assessment of GPU compute work. For the fully kinetic particle-in-cell code WarpX, which supports MPI+CUDA parallelism, we investigate the performance of the improved dynamic load balancing via a strong scaling-based performance model and show that, for a laser-ion acceleration test problem run with up to 6144 GPUs on Summit, the enhanced dynamic load balancing achieves from 62%--74% (88% when running on 6 GPUs) of the theoretically predicted maximum speedup; for the 96-GPU case, we find that dynamic load balancing improves performance relative to baselines without load balancing (3.8x speedup) and with static load balancing (1.2x speedup). Our results provide important insights into dynamic load balancing and performance assessment, and are particularly relevant in the context of distributed memory applications ran on GPUs.

description: We have studied charge transport in a one-dimensional chain of small Josephson junctions using a single-electron transistor. We observe a crossover from time-correlated tunneling of single electrons to that of Cooper pairs as a function of both magnetic field and current. At relatively high magnetic field, single-electron transport dominates and the tunneling frequency is given by f=I/e, where I is the current through the chain and e is the electron's charge. As the magnetic field is lowered, the frequency gradually shifts to f=I/2e for I>200 fA, indicating Cooper-pair transport. For the parameters of the measured sample, we expect the Cooper-pair transport to be incoherent.

description: We report on the status of a users' end-station, MAC: a Multipurpose station for Atomic, molecular and optical sciences and Coherent diffractive imaging, designed for studies of structure and dynamics of matter in the femtosecond time-domain. MAC is located in the E1 experimental hall on the high harmonic generation (HHG) beamline of the ELI Beamlines facility. The extreme ultraviolet beam from the HHG beamline can be used at the MAC end-station together with a synchronized pump beam (which will cover the NIR/Vis/UV or THz range) for time-resolved experiments on different samples. Sample delivery systems at the MAC end-station include a molecular beam, a source for pure or doped clusters, ultrathin cylindrical or flat liquid jets, and focused beams of substrate-free nanoparticles produced by an electrospray or a gas dynamic virtual nozzle combined with an aerodynamic lens stack. We further present the available detectors: electron/ion time-of-flight and velocity map imaging spectrometers and an X-ray camera, and discuss future upgrades: a magnetic bottle electron spectrometer, production of doped nanodroplets and the planned developments of beam capabilities at the MAC end-station.
