description: Power talk is a novel concept for communication among control units in MicroGrids (MGs), carried out without a dedicated modem, but by using power electronics that interface the common bus. The information is transmitted by modulating the parameters of the primary control, incurring subtle power deviations that can be detected by other units. In this paper, we develop power talk communication strategies for DC MG systems with arbitrary number of control units that carry out all-to-all communication. We investigate two multiple access strategies: 1) TDMA, where only one unit transmits at a time, and 2) full duplex, where all units transmit and receive simultaneously. We introduce the notions of signaling space, where the power talk symbol constellations are constructed, and detection space, where the demodulation of the symbols is performed. The proposed communication technique is challenged by the random changes of the bus parameters due to load variations in the system. To this end, we employ a solution based on training sequences, which re-establishes the signaling and detection spaces and thus enables reliable information exchange. The presented results show that power talk is an effective solution for reliable communication among units in DC MG systems.

description: Perceived control is an important construct for the psychological well-being of people affected by chronic conditions, and higher perceived control is associated with better outcomes. Psychosocial interventions have been trialled in these populations to improve both global and specific perceptions of control. However, most interventions involving people with Parkinson’s have focused on single-domain forms of control, while those addressing global perceived control are yet to be reviewed. This study aimed to identify and map the types of psychosocial interventions in individuals with Parkinson’s which have included forms of global perceived control as an outcome. Scoping review based on a search across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate. From an initial return of 4388 citations, 12 citations were eventually included. These consisted of 8 quantitative and 4 qualitative studies, and covered 4 overarching categories of psychosocial interventions. Mixed results were found for cognitive, educational, and physical interventions, while a randomised controlled trial on mindfulness-based lifestyle programme showed more preliminary positive evidence. Further rigorous research is required on the topic to build on these preliminary findings. In the meantime, clinicians may need to consider programmes which proved effective with populations similar to people with Parkinson’s.IMPLICATIONS FOR REHABILITATIONPerceived control is a psychological construct important for people with chronic illnesses, which can be targeted by behavioural interventions.This article reviewed behavioural interventions targeting global forms of perceived control in Parkinson’s.Mixed results were reported for the cognitive, educational, and physical interventions identified, while a randomised controlled trial on a mindfulness-based lifestyle programme showed more promising evidence.In the meantime, clinicians may need to consider programmes found to be effective with people with similar conditions to Parkinson’s.

Hyalosynedra hyalina

description: Hyalosynedra hyalina (Grunow) Álvarez-Blanco and S. Blanco (Figs 17–19)
 Basionym: — Synedra laevigata var. hyalina Grunow (1877, 166)
 Material studied: —Wild (KSA 2015-14) and cultured (UTKSA 0189) material from algal turfs collected at 1 m depth near the Bhadur Resort, Jeddah, Kingdom of Saudi Arabia.
 Description: —Valves were 25.9–90.3 μm in length, and 3.3–6.2 μm in width (Fig 17, 19). Each sternum was evenly thin along the entire valve (Figs 18, 19). Apices were protruded and capitate. Valves had finely packed virgae (56– 60 in 10 μm) separated by biseriate striae. The weakly sunken ocellulimbi were 3 rows of pores tall externally, at least 4 rows tall internally (Fig. 18), and about 14 pores wide. Usually 2 spines were over each ocellulimbus. There was an asymmetric rimoportula at each apex occurring at the junction of the terminal depression. Girdle bands were dissociated from one another and the valves in the cleaned cultured material, but all girdle bands found were without pores and all were open (not illustrated).
 Remarks: —Although the largest specimens were slightly larger than those previously reported (Álvarez-Blanco & Blanco 2014), they were alike in other respects with illustrated specimens of S. laevigata var. hyalina (Grunow 1877) and of H. hyalina (Álvarez-Blanco & Blanco 2014). Unlike the apices of H. laevigata, those of H. hyalina were strongly protruded and capitate.

The Relationship between Imitation at 12 months and Language and Self-Regulation at 42 months
Creators: name: Strenk, Laura
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Theory of Mind (ToM) is a multidimensional construct associated with many other domains, such as imitation, self-regulation, and language. Early imitation is believed to be one of the earliest indicators of ToM. Language and self-regulation skills are concurrently associated with ToM because effective communication requires ToM and because the ability to regulate oneself is tied to mental state concepts. Previous research has found connections between early imitation and language, but researchers have not explicitly explored the connection between imitation and self-regulation. In this longitudinal study, 12-month old imitation scores were obtained from a parent-report survey and behavioral data were collected from a sample of 42-month old children in order to measure receptive language, expressive language, and delay inhibitory control (which is an indicator of self-regulation). It was hypothesized that better imitation scores at 12 months would predict better performance on both language measures and self-regulation at 42 months, but this hypothesis was not supported. It was hypothesized that higher language scores would be related to higher self-regulation scores. This study supported this hypothesis by finding that higher simple expressive language scores were associated with higher scores on self-regulation tasks. It was hypothesized that there would be gender differences in mean scores on imitation, language, and self-regulation such that girls would perform better. It was also hypothesized that gender would moderate the relationship between imitation and language and self-regulation. Overall, gender was not found to be significant in either of these capacities. Results from this study will be able to inform future early intervention programs, particularly for children with Autism Spectrum Disorder.

description: We present a comprehensive theoretical study of the magnetic field dependence of the near-field radiative heat transfer (NFRHT) between two parallel plates. We show that when the plates are made of doped semiconductors, the near-field thermal radiation can be severely affected by the application of a static magnetic field. We find that irrespective of its direction, the presence of a magnetic field reduces the radiative heat conductance, and dramatic reductions up to 700% can be found with fields of about 6 T at room temperature. We show that this striking behavior is due to the fact that the magnetic field radically changes the nature of the NFRHT. The field not only affects the electromagnetic surface waves (both plasmons and phonon polaritons) that normally dominate the near-field radiation in doped semiconductors, but it also induces hyperbolic modes that progressively dominate the heat transfer as the field increases. In particular, we show that when the field is perpendicular to the plates, the semiconductors become ideal hyperbolic near-field emitters. More importantly, by changing the magnetic field, the system can be continuously tuned from a situation where the surface waves dominate the heat transfer to a situation where hyperbolic modes completely govern the near-field thermal radiation. We show that this high tunability can be achieved with accessible magnetic fields and very common materials like n-doped InSb or Si. Our study paves the way for an active control of NFRHT and it opens the possibility to study unique hyperbolic thermal emitters without the need to resort to complicated metamaterials.

Parsec-scale jets of FR0 radio galaxies

Publisher: name: Zenodo

description: Radio galaxies (RGs) are active galactic nuclei (AGN) able to launch relativistic jets, the most energetic phenomena in the Universe, which can have a large impact on galaxy evolution. Current high-sensitivity and high-resolution surveys have shed new light on properties of RGs, particularly in the local Universe (z<0.3) and at low luminosities (<10^24 W/Hz a 1.4 GHz), where the bulk of the AGN population was not much explored in opposition to the well-studied powerful RGs. A large population of compact RGs, named FR0s, which differ from classical FRI/II RGs, by lacking large-scale (>10 kpc) jet emission, is emerging from recent studies and is revolutionising our idea of an ordinary RG. These compact sources show host and nuclear characteristics similar to those of FRI RGs. However, in the radio band, while FR0s and FRIs share the same core properties, the kpc-scale diffuse component dominant in FRI is missing in FR0s. VLBI observations of FR0s can probe the parsec-scale region to study their actual capability of launching jets with respect to FRIs. I will present VLBA, EVN and eMERLIN observations of a sample of FR0s, which provide evidence that parsec-scale jets in FR0s are mildly relativistic with a bulk velocity on the order of 0.5c or less. A jet structure with a thin inner relativistic spine surrounded by a low-velocity sheath could be in agreement with the observed FR0 properties.
Causal Relationship and Volatility Spillover between Chinese CSI 300 Index and Index Futures

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The CSI 300 is a market index that reflects the performance of the Chinese stock market by tracking the price fluctuations of 300 major stocks traded in China. This paper examines the causal relationship and volatility spillover between two prices of the CSI 300, the one in the stock market and the one in the futures market. Empirical studies on various developed markets show that changes in futures prices can help predict changes in stock prices. In other words, the futures market play a dominant role in the price discovery process. A study by Yang, Yang, and Zhou (2010), however, find that the above relationship does not apply to the CSI 300. High barriers of entry to the futures market are cited as a possible explanation. The data we use in this paper, prices of the CSI 300 from March 2015 to September 2015, cover a period of low entry barriers in the first three months and a period of rising barriers afterwards. By using a vector error correction model (VECM) for mean causality, we find that changes in futures prices cause changes in stock prices in the sense of Granger (1969) when barriers are low, and is non-causal when barriers are high. We also use an extended Q-test for volatility spillover and find evidence of bi-directional volatility spillover when barriers are low but only unidirectional futures-to-stock spillover when barriers are high.

Hyalosynedra sublaevigata

description: Hyalosynedra sublaevigata Álvarez-Blanco and S. Blanco (Figs 20–26)
 Material studied: —Wild material (ECT 4119) from subtidal sediments and benthic scrapings collected near the Caribe Hilton at Condado Lagoon, San Juan, Puerto Rico (18° 27.6’ N, 66 °5.1’ W).
 Description: —Valves were 28.6–92.1 μm long and 2.5–5.3 μm wide (Figs 20–22, 25). Outlines were lanceolate: convex in the middle and either linear to weakly convex in the flanks narrowing towards the apices. The ends either continued to converge, or exhibited a weak concave reflex. Each sternum was lanceolate (thicker in the middle than at the apices of the valve: Figs 20, 21, 23, 24). Striae were biseriate. Virgae were densely packed (50–54 in 10 μm). An asymmetric rimoportula occurred at each pole (Figs 23, 24, 26). Girdle bands were dissociated from one another and the valves in the cleaned cultured material, but all girdle bands found in the cultured material were without pores and all were open (not illustrated).
 Remarks: —Our Puerto Rican specimens overlapped in measurements reported for Mediterranean Sea type material (26.5–34.1 μm long, 2.3–3.0 μm wide, Álvarez-Blanco & Blanco 2014), and had the same valve outline and lanceolate sternum. Both had asymmetric rimoportulae, and ocellulimbi were of the same dimensions (6–8 pores wide by three high). Girdle band morphology was not reported for the type, so no comparison between our material and the type material is possible.

description: We present new integral representations in two dimensions for the elastance problem in electrostatics and the mobility problem in Stokes flow. These representations lead to resonance-free Fredholm integral equations of the second kind and well conditioned linear systems upon discretization. By coupling our integral equations with high order quadrature and fast multipole acceleration, large-scale problems can be solved with only modest computing resources. We also discuss some applications of these boundary value problems in applied physics.

description: The dynamics of a classical heavy particle moving in a quantum environment is determined by a Langevin equation which encapsulates the effect of the environment-induced reaction forces on the particle. For an open quantum system these include a Born-Oppenheimer force, a dissipative force and a stochastic force due to shot and thermal noise. Recently it was shown that these forces can be expressed in terms of the scattering matrix of the system by considering the classical heavy particle as a time-dependent scattering center, allowing to demonstrate interesting features of these forces when the system is driven out of equilibrium. At the same time, it is well known that small changes in a scattering potential can have a profound impact on a fermionic system due to the Anderson orthogonality catastrophe. In this work, by calculating the Loschmidt echo, we relate Anderson orthogonality effects with the mesoscopic reaction forces for an environment that can be taken out of equilibrium. In particular we show how the decay of the Loschmidt echo is characterized by fluctuations and dissipation in the system and discuss different quench protocols.

Hyalosynedra prasadii

description: Hyalosynedra prasadii Theriot and Ashworth (Figs 37–43)
 Holotype: — ANSP G. C. 59325
 Isotypes: — ECT 4118 in the Theriot collection at the UT Austin.
 Type locality: —Epiphyte on Anadyomene spp. thalli from Rabbit Key Basin, Florida, USA (24 o 58.60’ N, 80 o 50.41’ W).
 Material studied: —Wild material and cultured (21IV14-4D “araphid-31”) material isolated from the type locality: ECT 4118, epiphyte samples taken from Anadyomene spp. thalli from Rabbit Key Basin, Florida, USA (24 o 58.60’ N, 80 o 50.41’ W).
 Description: —Valves observed were 43.1–109.3 μm long and 3.6–6.9 μm wide (Figs 37–40). Outlines were lanceolate, with sides being convex to near the apex where there was often a slight reversal in curve, producing slightly protracted apices. The sternum was strongly lanceolate, about twice as wide in the middle as at the apices. Virga densities were 42–48 in 10 μm. Pore densities in the ocellulimbus were 5.5–8.0 in 10 μm (Figs 41–43). Ocellulimbi were about 10–14 pores wide and 3 pores tall and overhung with 1–4 small spines. Each asymmetric rimoportula was positioned inside a slight depression at each apex. The rimoportula, however, was often very close to the valve end compared to other species of Hyalosynedra. Girdle bands were without pores and open (Fig. 41).
 Remarks: — Hyalosynedra prasadii was isolated from Rabbit Key Basin along with H. laevigata, and was recovered as sister to all other nominal Hyalosynedra species of this study in the molecular analysis (Fig. 1). The sternum of H. laevigata was linear, that of H. prasadii was lanceolate, and the former was observed to be much larger than the latter.
 Etymology: —This species was named for A.K.S.K. Prasad, in honor of his many contributions to our understanding of diatom diversity, especially that of the Florida coast.

description: In higher organisms, all cells share the same genome, but every cell expresses only a limited and specific set of genes that defines the cell type. During cell division, not only the genome, but also the cell type is inherited by the daughter cells. This intriguing phenomenon is achieved by a variety of processes that have been collectively termed epigenetics: the stable and inheritable changes in gene expression patterns. This article reviews the extremely rich and exquisitely multi-scale physical mechanisms that govern the biological processes behind the initiation, spreading and inheritance of epigenetic states. These include not only the changes in the molecular properties associated with the chemical modifications of DNA and histone proteins, such as methylation and acetylation, but also less conventional ones, such as the physics that governs the three-dimensional organization of the genome in cell nuclei. Strikingly, to achieve stability and heritability of epigenetic states, cells take advantage of many different physical principles, such as the universal behavior of polymers and copolymers, the general features of non-equilibrium dynamical systems, and the electrostatic and mechanical properties related to chemical modifications of DNA and histones. By putting the complex biological literature under this new light, the emerging picture is that a limited set of general physical rules play a key role in initiating, shaping and transmitting this crucial "epigenetic landscape". This new perspective not only allows to rationalize the normal cellular functions, but also helps to understand the emergence of pathological states, in which the epigenetic landscape becomes dysfunctional.

Results from the EVN follow-up study of a sample of milli-lens candidates

Publisher: name: Zenodo

description: The SMILE (Search for MIlli LEnses) project (see talk by Carolina Casadio, also Casadio et al. 2021) aims at discerning the number of milli-lens systems in a sample of ~5000 sources based on the CLASS VLA survey at 8 GHz, observed with Very-Long-Baseline Interferometry (VLBI) at milliarcsecond resolution.
 In a pilot project, we have searched for milli-lens candidates in a sample consisting of 13,828 compact radio sources from the Astrogeo VLBI FITS image database at 5 and 8 GHz to identify lens candidates. Forty candidates with compact double structures have been found using a citizen-science approach, for which I will present the ongoing analysis of EVN follow-up observations at 5 and 22 GHz in phase-referencing mode. These observations with increased sensitivity and frequency coverage allow us to better constrain the nature of the lens candidates.
 We find some interesting sources that are still viable lens candidates, given constrains such as surface brightness ratio, stability of flux density ratio of components over time, and their spectrum. Other sources are potential compact symmetric objects or even binary black hole candidates, and thus also deserve closer attention.

Prevalence, Incidence and Impact of Sexual and Gender-Based Violence  in Areas of Humanitarian Conflict: A Systematic Review
Creators: name: Spinelli, Adria N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Background: Women and children are disproportionately targeted for violence in conflict and
require higher levels of protection (Ward & Marsh, 2006). The United Nations estimates that
35% of women and girls experience sexual and gender-based violence (SGBV) in their lifetime
(World Health Organization, 2013). Methods: PubMed/Medline, CINHAL, Google Scholar and
Cochrane Database of Systemic Reviews journals and grey literature was searched looking for
incidence, prevalence and impacts of SGBV in conflict-affected countries. Results: Out of the
3,551 returned studies, 89 studies were assessed for eligibility. Of the 10 studies that met the
inclusion and exclusion criteria, one was a randomized cohort study, four were non-randomized
cohort studies, three were retrospective cohort analyses and two were cross-sectional surveys.
Studies occurred in the Democratic Republic of Congo (DRC), East Timor, Uganda and mixed
(Burundi, DRC, Rwanda, Sierra Leone, Somalia, southern Sudan, Uganda). All focused on
examining incidence, prevalence and impacts of SGBV in conflict. Conclusions: Although
limited, these studies demonstrate the increased incidence and prevalence of SGBV in conflict.
Girls are disproportionality, more intensely impacted. Impacts for women and girls affected by
SGBV range from intense psychosocial impacts and physical symptoms ranging from traumatic
fistulas, pregnancy, abdominal pain, chronic pain, urinary incontinence, generalized malaise and
symptoms of sexually transmitted infections.

description: A direct numerical solution of the radiative transfer equation or any kinetic equation is typically expensive, since the radiative intensity depends on time, space and direction. An expansion in the direction variables yields an equivalent system of infinitely many moments. A fundamental problem is how to truncate the system. Various closures have been presented in the literature. We want to study moment closure generally within the framework of optimal prediction, a strategy to approximate the mean solution of a large system by a smaller system, for radiation moment systems. We apply this strategy to radiative transfer and show that several closures can be re-derived within this framework, e.g. $P_N$, diffusion, and diffusion correction closures. In addition, the formalism gives rise to new parabolic systems, the reordered $P_N$ equations, that are similar to the simplified $P_N$ equations. Furthermore, we propose a modification to existing closures. Although simple and with no extra cost, this newly derived crescendo diffusion yields better approximations in numerical tests.

Trotz der Vorteile von M&A kann es auch Hindernisse geben, die einen erfolgreichen Deal behindern können. Darüber hinaus wurde die neue Form der europäischen Gesellschaft, Societas Europaea (SE), im Jahr 2001 angenommen und ist in den letzten Jahren in der Europäischen Union aufgrund seiner einzigartigen Vorteile beliebt geworden, die andere Rechtsformen nicht haben. Entweder M&A oder SE hat immer noch ihre eigenen finanziellen und rechtlichen Aspekte und Hindernisse, die in diesem Papier identifiziert, analysiert und ausgewertet werden.

The process of merger can create a synergy with other companies, improve their financial situation, and produce new and different goods, giving them a stronger position in the market. Despite the advantages of M&As, there could also be obstacles that can interfere with a successful deal. In addition, the new form of the European Company, Societas Europaea (SE), was adopted in 2001 and has become popular in the European Union in the last few years due to its unique benefits, which other legal forms do not have. Either M&A or SE still has its own financial and legal aspects and obstacles that are identified, analyzed, and evaluated in this paper.

description: Given a normal complete variety $Y$ over an algebraically closed field $\mathbb K$, distinct effective Weil divisors $D_1,... D_n$ of $Y$ and positive integers $d_1,... d_n$, we spell out the conditions for the existence of an abelian cover of $Y$ branched with order $d_i$ on $D_i$. As an application, we prove that a cover of a normal complete toric variety branched on the torus-invariant divisors is itself a toric variety if the characteristic of $\mathbb K$ is equal to 0 or if the cover is Galois of degree not divisible by the characteristic.

description: We present and discuss the results of the Herschel Gould Belt survey observations in a ~11 deg^2 area of the Aquila molecular cloud complex at d~260 pc, imaged with the SPIRE/PACS cameras from 70 to 500 micron. We identify a complete sample of starless dense cores and embedded protostars in this region, and analyze their global properties and spatial distributions. We find a total of 651 starless cores, ~60% of which are gravitationally bound prestellar cores, and they will likely form stars in the future. We also detect 58 protostellar cores. The core mass function (CMF) derived for the prestellar cores is very similar in shape to the stellar initial mass function (IMF), supporting the earlier view that there is a close physical link between the IMF and the CMF. The global shift in mass scale observed between the CMF and the IMF is consistent with a typical star formation efficiency of ~40%. By comparing the numbers of starless cores to the number of young stellar objects, we estimate that the lifetime of prestellar cores is ~1 Myr. We find a strong correlation between the spatial distribution of prestellar cores and the densest filaments. About 90% of the Herschel-identified prestellar cores are located above a background column density corresponding to A_V~7, and ~75% of them lie within filamentary structures with supercritical masses per unit length >~16 M_sun/pc. These findings support a picture wherein the cores making up the peak of the CMF (and probably responsible for the base of the IMF) result primarily from the gravitational fragmentation of marginally supercritical filaments. Given that filaments appear to dominate the mass budget of dense gas at A_V>7, our findings also suggest that the physics of prestellar core formation within filaments is responsible for a characteristic "efficiency" SFR/M_dense ~5+-2 x 10^-8 yr^-1 for the star formation process in dense gas.

Divergita toxoneides

description: Divergita toxoneides (Castracane) Theriot comb. nov. (Figs 49–53)
 Basionym: — Synedra toxoneides Castracane (1880, 105)
 Synonyms: — Hyalosynedra toxoneides (Castracane) Perez-Coca, Chang, Wang and Wang (2017, 514)
 Material studied: —WK57, from the laboratory of WHCF Kooistra, off Ischia, near Naples, Italy (Medlin et al. 2008, Kooistra et al. 2009).
 Description: —The one complete specimen imaged measured 173.6 μm long and 4.4 um wide and was curved along the center line, with margins converging steadily towards the apices (Fig. 49). The ends were subcapitate (Figs 49–51). The external areolar pore pattern was decussate (Figs 52, 53). The internal membrane was perforated by a row of pores, one between each pair of virgae at the face-mantle junction. Virgae were 24–28 in 10 μm. The ocellulimbi were very weakly sunken (Figs 50, 53), about 14 pores wide and 3 pores tall, and without spines. The sternum was broad and lanceolate in shape. A rimoportula occurred at each pole and each was weakly asymmetric. Images provided by Dr. Kooistra did not show girdle bands.
 Remarks: —This strain was previously identified and illustrated by SEM in Kooistra et al. (2009). Additional observations reported here include information on the asymmetric rimoportulae, and overall valve shape. Perez-Coca et al. (2017) illustrated deformed specimens identified also as H. toxoneides, based primarily on the similarity of the areolar pattern and the near-identity of SSU sequences (the aligned SSU sequences of Perez-Coca strain AQ10 from coastal Taiwan and Kooistra WK57 from the Mediterranean Sea differ by only two base pairs, one of which is an indel.) Girdle bands in the coastal Taiwan specimens were without pores and open.

Surveys using VLBI – the past, present, and its bright future
Creators: name: Radcliffe, Jack
Publisher: name: Zenodo
Year: 2023

description: For over 20 years, a significant effort has been made to map the milliarcsecond sky with VLBI. The largest surveys are targeted and require many years of observations to build up an extensive sample. However, computational improvements have enabled us to map the entire primary beam of VLBI arrays and push into the lower frequency regime through the International LOFAR telescope. In this talk, I will talk about the scientific and technical discoveries arising from such surveys and focus on the bright future of VLBI surveys. This includes the transition from the current modus operandi of a small number of surveys of a few "famous" deep fields to a ubiquitous VLBI survey instrument. I will touch on other developments, such as the incorporation of SKA and MeerKAT, ultra-wideband receivers, and GPU-accelerated correlation and calibration.

description: Introduced by Okounkov and Reshetikhin, the Schur process is known to be a determinantal point process, meaning that its correlation functions are minors of a single correlation kernel matrix. Previously, this was derived using determinantal expressions for the skew-Schur polynomials. In this paper we obtain this result in a different way, using the fact that the Schur polynomials are eigenfunctions of Macdonald difference operators.

Implicit Positivity: Improving Mood with Environmental Cues
Creators: name: Kramer, Amanda
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Research in recent years has touted the benefits of positive emotions. However, new studies suggest that actively trying to be positive can backfire, leaving a person feeling worse than before. In this study, the efficacy of implicit goals of positivity as an alternate mechanism for mood improvement was investigated. All participants completed a negative mood induction before completing a thought task while being exposed to either positive or neutral environmental cues. During the task, participants were either asked to try to “improve their mood” or to list whatever thoughts came to their mind. A variety of measures, including number of thoughts, thought automaticity, thought valence, and degree of mood repair were collected across conditions. Despite research to the contrary, most participants experienced greater positivity when given an explicit goal to try to be positive. However, among participants prone to rumination, implicit goals were comparatively more effective in generating positivity. Though the implicit mechanism of environmental cues may not be effective for all people, it seems to be preferable for those with a tendency to dwell on negative thoughts. The possibilities for follow-up research and for practical applications of such findings are discussed.
The SMILE (Search for MIli-LEnses) project
Creators: name: Casadio, Carolina
Publisher: name: Zenodo
Year: 2023

description: Several methods are employed in projects seeking to understand the elusive nature of dark matter. The approach used by the Search for MIlli-LEnses (SMILE) project makes use of strong gravitational lens systems in the milliarcsecond regime, where the lens is a compact object with mass between ~ 10^6 and 10^9 solar masses. This mass range is crucial for the widely accepted ΛCDM cosmological model, which predicts the existence of many more DM sub-galactic halos ( < 10^11 solar masses), than the currently observed number. To explore such small angular scales, high-resolution radio VLBI data are used. Searching for milli-lenses in a catalog of ~ 5000 radio loud sources, will allow us to detect lenses in this mass range, or, failing that, to tighten significantly our constraints on the number of sub-galactic halos and consequently discard some viable DM models, as we demonstrated in Loudas et al., 2022 (2022A&A...668A.166L).

description: We present combined experimental and theoretical studies on the magnetic properties of a solid solution between yttrium orthoferrite and yttrium orthochromite systems, YFe$_{1-x}$Cr$_x$O$_3$ (0 $\leq$ x $\leq$ 1) where Fe$^{3+}$ and Cr$^{3+}$ ions are distributed randomly at the same crystallographic site (4b). We found that all the compositions exhibit weak ferromagnetism below the Néel temperature that decreases non-linearly with increasing $x$, while certain intermediate compositions ($x = 0.4,0.5$) show a compensation point and magnetization reversal. This unusual behavior is explained based on a simple model comprising the isotropic superexchange and the antisymmetric Dzyaloshinskii-Moriya interactions. This model explains the magnetization behavior in the entire range of doping and temperature including the magnetization reversal which results from an interplay of various DM interactions such as, Fe-O-Fe, Cr-O-Cr and Fe-O-Cr.

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: In this paper, we introduce an application-aware approach for resource block scheduling with carrier aggregation in Long Term Evolution Advanced (LTE-Advanced) cellular networks. In our approach, users are partitioned in different groups based on the carriers coverage area. In each group of users, users equipments (UE)s are assigned resource blocks (RB)s from all in band carriers. We use a utility proportional fairness (PF) approach in the utility percentage of the application running on the UE. Each user is guaranteed a minimum quality of service (QoS) with a priority criterion that is based on the type of application running on the UE. We prove that our scheduling policy exists and therefore the optimal solution is tractable. Simulation results are provided to compare the performance of the proposed RB scheduling approach with other scheduling policies.

description: MDRC’s RCT evaluation of CUNY’s ASAP found among the largest estimated impacts on credit accumulation and graduation rates of any postsecondary program. The Westchester ASAP Replication, “Viking ROADS”, aims to determine whether CUNY’s ASAP can be replicated at Westchester Community College and whether it will improve academic outcomes for these students. To answer whether Viking ROADS improves academic outcomes, we will estimate the average (across persons) intent-to-treat effect of the program on academic progress and completion through three years after random assignment. Westchester Community College will recruit and enroll about 300 students in fall 2018 and another 300 students in fall 2019, for around 600 students in the study. The study will use a random assignment design to estimate the average causal effect of the opportunity to participate in Viking ROADS.
