description: Soft condensed matter structures often challenge us with complex many-body phenomena governed by collective modes spanning wide spatial and temporal domains. In order to successfully tackle such problems mesoscopic coarse-grained (CG) statistical models are being developed, providing a dramatic reduction in computational complexity. CG models provide an intermediate step in the complex statistical framework of linking the thermodynamics of condensed phases with the properties of their constituent atoms and molecules. These allow us to offload part of the problem to the CG model itself and reformulate the remainder in terms of reduced CG phase space. However, such exchange of pawns to chess pieces, or ``Hamiltonian renormalization'', is a radical step and the thermodynamics of the primary atomic and CG models could be markedly different. Here, we present a comprehensive study of the phase diagram including binodal and interfacial properties of a novel soft CG model, which includes finite-range attraction and supports liquid phases. Although the model is rooted in similar arguments to the Lennard-Jones (LJ) atomic pair potential, its phase behaviour is qualitatively different from that of LJ and features several anomalies such as an unusually broad liquid range, change in concavity of the liquid coexistence branch with variation of the model parameters, volume contraction on fusion, temperature of maximum density in the liquid phase and negative thermal expansion in the solid phase. These results provide new insight into the connection between simple potential models and complex emergent condensed matter phenomena.

Observable cosmological vector mode in the dark ages
Creators: name: Saga, Shohei
Publisher: name: arXiv
Year: 2016
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The second-order vector mode is inevitably induced from the coupling of first-order scalar modes in cosmological perturbation theory and might hinder a possible detection of primordial gravitational waves from inflation through 21cm lensing observations. Here, we investigate the weak lensing signal in 21cm photons emitted by neutral hydrogen atoms in the dark ages induced by the second-order vector mode by decomposing the deflection angle of the 21cm lensing signal into the gradient and curl modes. The curl mode is a good tracer of the cosmological vector and tensor modes since the scalar mode does not induce the curl one. By comparing angular power spectra of the 21cm lensing curl mode induced by the second-order vector mode and primordial gravitational waves whose amplitude is parametrized by the tensor-to-scalar ratio $r$, we find that the 21cm curl mode from the second-order vector mode dominates over that from primordial gravitational waves on almost all scales if $r \lesssim 10^{-5}$. If we use the multipoles of the power spectrum up to $\ell_{\rm max} = 10^{5}$ and $10^{6}$ in reconstructing the curl mode from 21cm temperature maps, the signal-to-noise ratios of the 21cm curl mode from the second-order vector mode achieve ${\rm S/N} \approx 0.46$ and $73$, respectively. Observation of 21cm radiation is, in principle, a powerful tool to explore not only the tensor mode but also the cosmological vector mode.

Sticking together:the ETS-transcription factor pointed regulates cell connectivity in the follicular epithelium
Creators: name: Stevens, Cody A.
Publisher: name: No Publisher Supplied
Year: 2022

description: Cell migration is a fundamental necessity for normal tissue development, as well as a requirement for the progression of metastatic cancer. This migratory capacity is regulated by numerous signaling pathways, transcription factors and cell-adhesion molecules. However, how these elements coordinate to give rise to cellular migration is not well understood. The follicular epithelium of the Drosophila egg chamber is an established model system to study cell migration. Here, I show the ETS transcription factor Pointed (PNT) is sufficient to arrest cell migration of the stretch follicle cells (StCs), and a subsect of cells known as border cells (BCs). This arrest is suggested to be coordinate through an inhibition of cell-adhesion release via shotgun, the Drosophila homolog of E-cadherin (DE-Cad). For the BCs, PNT expression was found to significantly downregulate slbo, a transcription factor necessary for BC formation. Migration of the BCs is partially rescued via co-expression of YAN, an antagonist of PNT. Finally, I suggest an evolutionary conserved role of PNT mediated regulation of E-Cad in Drosophila nebulosa. Together, I present a role for PNT mediated arrest of migratory cells in developing epithelial cells.

Creators: name: Gudina, Feyera
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The study is aims at understanding the link between inflation rate, national saving rate and per capita income growth rate in Ethiopia. To achieve this objective co-integrated VAR approach was employed. The estimated models enable to understand the long run and short run relationship of the variables for the period 1980 – 2014 in Ethiopia. The result shows that there is short run and long run relationship between the variables. The long run test results show that per capita income growth rate and inflation rate exert positive and significant impact on gross national saving rate; inflation rate and gross national saving rate exerts positive and significant impact on per capita income growth rate; per capita income growth rate exerts positive and significant impact on inflation rate where as gross national saving rate exerts negative and insignificant impact on inflation rate in the long run. The short run test results show that the impact of per capita income growth rate on gross national saving rate is positive and insignificant whereas the impact of inflation rate on gross national saving rate is negative and insignificant; inflation rate and gross national saving rate exerts positive and significant impact on per capita income growth rate; gross national savings rate and per capita income growth rate influence inflation rate positively in the short run time period in Ethiopia. The impulse response function indicates that the variables are at fast movement towards long run time path. Inferences drawn will have implications for all stakeholders in the economy and are particularly useful to monetary authorities or policy makers of the country.

description: A controlled sweeping process with prox-regular set, $W^{1,2}$-controls, and separable endpoints constraints is considered in this paper. Existence of optimal solutions is established and local optimality conditions are derived via strong converging continuous approximations that entirely reside in the interior of the prox-regular set. Consequently, these results are expressed in terms of new subdifferentials for the original data that are strictly smaller than the standard Clarke and Mordukhovich subdifferentials.

description: We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the S6 LIGO science run. The search was possible thanks to the computing power provided by the volunteers of the Einstein@Home distributed computing project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population. At the frequency of best strain sensitivity, between $170.5$ and $171$ Hz we set a 90% confidence upper limit of ${5.5}^{-25}$, while at the high end of our frequency range, around 505 Hz, we achieve upper limits $\simeq {10}^{-24}$. At $230$ Hz we can exclude sources with ellipticities greater than $10^{-6}$ within 100 pc of Earth with fiducial value of the principal moment of inertia of $10^{38} \textrm{kg m}^2$. If we assume a higher (lower) gravitational wave spindown we constrain farther (closer) objects to higher (lower) ellipticities.

description: Immer mehr Kinder und Jugendliche haben psychische Störungen und weisen Unterstützungsbedarf auf. Zudem werden die Problemstellungen stets komplexer. Die Arbeit mit Kindern und Jugendlichen mit psychischen Störungen ist eine Schnittstelle, an der Professionelle der Sozialpädagogik und der Psychotherapie aufeinandertreffen. Dabei erscheint multiprofessionelle Kooperation zunehmend notwendig, damit Adressat*innen zu einer gesunden, unabhängigen Lebensführung in stabilen Lebensverhältnissen ermächtigt werden können. Dies stellt das gemeinsame Ziel der Arbeitsfelder dar. Diese Arbeit beschäftigt sich mit der Bedeutung multiprofessioneller Kooperation im Kontext der Arbeit mit Kindern und Jugendlichen mit psychischen Störungen, die im sozialpädagogischen Heimsetting leben. Leitend ist dabei die Frage nach dem Grundverständnis der Sozialpädagogik und der Psychotherapie und wie professionelles Handeln definiert wird. Welches Potenzial für multiprofessionelle Kooperation zeigt sich konkret anhand relevanter Aspekte professionellen Handelns? Die Erkenntnisse der Arbeit weisen darauf hin, dass verschiedene Faktoren für eine Kooperation der Fachpersonen sprechen – sowohl auf professionstheoretischer Ebene als auch auf der konkreten Handlungsebene. Auf Grundlage dessen wird für die Sozialpädagogik empfohlen, dass Fachpersonen multiprofessionelle Kooperation als Bestandteil ihrer professionellen Tätigkeit verstehen und sich ein Grundverständnis der Psychotherapie und deren Auftrags aneignen. Sie sollen ihr Handeln kooperativ gestalten, dabei einen aktiven Informations- und Wissensaustausch anstreben und sich für die Schaffung günstiger Ausgangsbedingungen für die Kooperation einsetzen.

description: Motivated by UV completion of general relativity with a modification of a geometry at high energy scale, it is expected to have an energy dependent geometry. In this paper, we introduce charged black hole solutions with power Maxwell invariant source in the context of gravity's rainbow. In addition, we investigate two classes of $F(R)$ gravity's rainbow solutions. At first, we study energy dependent $F(R)$ gravity without energy momentum tensor, and then we obtain $F(R)$ gravity's rainbow in the presence of conformally invariant Maxwell source. We study geometrical properties of the mentioned solutions and compare their results. We also give some related comments regarding to thermodynamical behavior of the obtained solutions and discuss thermal stability of the solutions.

Information locking and its resource efficient extraction

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Locally indistinguishable states are useful to distribute information among spatially separated parties such that the information is locked. This implies that the parties are not able to extract the information completely via local operations and classical communication (LOCC) while it might be possible via LOCC when the parties share entanglement. In this work, we consider an information distribution protocol using orthogonal states for m >= 3 spatially separated parties such that even if any k <= (m-1) parties collaborate still the information cannot be revealed completely. Such a protocol is useful to understand up to what extent the encoded information remains locked. However, if required, the parties can share entanglement and extract the information completely by LOCC. To make the process resource efficient, it should consume less number of entangled states. We show that though the set of states, which are locally indistinguishable across every bipartition, are sufficient for the above protocol, they may consume higher number of entangled states when aiming for complete information extraction. We establish this by constructing a class of locally indistinguishable sets of orthogonal states which can be employed to accomplish the above protocol and these sets consume less number of entangled states, compared to the former sets, for complete information extraction. In fact, this difference in the number of required entangled states for complete information extraction grows linearly with the number of parties. This study sheds light on suitable use of local indistinguishability property of quantum states as resource and thus, we demonstrate an efficient way of information distribution.

description: Quantum speed limits (QSLs) provide lower bounds on the minimum time required for a process to unfold by using a distance between quantum states and identifying the speed of evolution or an upper bound to it. We introduce a generalization of QSL to characterize the evolution of a general operator when conjugated by a unitary. The resulting operator QSL (OQSL) admits a geometric interpretation, is shown to be tight, and holds for operator flows induced by arbitrary unitaries, i.e., with time- or parameter-dependent generators. The derived OQSL is applied to the Wegner flow equations in Hamiltonian renormalization group theory and the operator growth quantified by the Krylov complexity.

description: We prove a no charged scalar hair theorem for static black holes in de-Sitter spacetime in the region between the event horizon and the cosmological horizon. The proof does not depend on the assumption of spherical symmetry. It allows for general non-minimal coupling functions of the scalar field to gravity and electromagnetic fields, and for higher curvature term corrections to Einstein gravity. The extension to other asympitotic spacetimes is applicable by requiring appropriate boundary conditions. Our result excludes the possibility for spontaneous scalarization of charged scalar around static charged de-Sitter black holes.

Macroeconomic Policy and Poverty Reduction in Ethiopia: A General Equilibrium Approach

Year: 2003

description: This study presents a case study assessing instructors' provision of written responses to students' business letter writing practices at Admas College, a privately run business college in Addis Ababa. The goal is to examine, by means of detailed analysis of sample data gathered from 20 students, who are selected by availability sampling and instructors responses handling the course. Two instruments were used. A format with four micro- skills and conditions set for rating the instructors' formative responses against given rating scales was prepared. Then, the results were tabulated and analysed. The results showed that most of the students' works were rated below adequate standard and only a few of the students works were able to meet required letter writing standards. Then, the instructors written comments were collected and categorised using a format with six categories for which features were specified for characterising the instructors' comments. Using the six categories, the comments were summarised showing categories of clarity, style, form, reorganisation, provision of more information, and provision of less information. The results showed that a good number of the comments revolved around issues of clarity, style, and form, whereas lesser number of the comments were to do with issues of reorganisation, provision of more and/or less information. Moreover, it was observed that quite a good number of the comments were either too general to follow, or too strong or harsh, and did not teach or help the students to overcome their writing difficulties. On the other hand, however, significant number ofthe comments seems to have met the students' preferences to a certain extent. Based on the finding of the study, some possible recommendations are suggested.

description: We present a sample of 59 periodic variables from the Palomar Transient Factory, selected from published catalogues of white dwarf (WD) candidates. The variability can likely be attributed to ellipsoidal variation of the tidally distorted companion induced by the gravity of the primary (WD or hot subdwarf) or to the reflection of hot emission by a cooler companion. We searched 11311 spectroscopically or photometrically selected WD candidates from three hot star/WD catalogues, using the Lomb-Scargle periodogram to single out promising sources. We present period estimates for the candidates, 45 of which were not previously identified as periodic variables, and find that most have a period shorter than a few days. Additionally, we discuss the eclipsing systems in our sample and present spectroscopic data on selected sources.

description: In this paper, a magnon-bandgap controllable artificial domain wall waveguide is proposed by means of micromagnetic simulation. By the investigation of the propagation behavior and dispersion relationship of spin waves in artificial domain wall waveguides, it is found that the nonreciprocal propagation of spin waves in the artificial domain walls are mainly affected by the local effective exchange field, and the magnon bandgap can be controlled by changing the maximum value of the effective exchange field. In addition, it is observed that the artificial domain wall waveguides are structurally more stable than the natural domain wall waveguides under the same spin wave injection conditions, and the magnon bandgap of the artificial domain wall waveguides can be adjusted by its width and magnetic anisotropy parameters. The bandgap controllable artificial domain wall scheme is beneficial to the miniaturization and integration of magnon devices and can be applied to future magnonic technology as a novel frequency filter.

description: A calorimetric measurement has recently been proposed as a promising technique to measure thermodynamic quantities in a dissipative superconducting qubit. These measurements rely on the fact that the system is projected into energy eigenstates whenever energy is exchanged with the environment. This requirement imposes a restriction on the class of systems that can be measured in this way. Here we extend the calorimetric protocol to the measurement of a driven quantum harmonic oscillator. We employ a scheme based on the two-level approximation to define a new work quantity and show how its statistics relates to the standard two-measurement protocol. We find that for the average work the two-level approximation holds in the underdamped regime for short driving times and, in the overdamped regime, for any driving time. However, this approximation fails for the variance and higher moments of work at finite temperatures. Furthermore, we show how to relate the work statistics obtained through this scheme to the work statistics given by the two-measurement protocol.

Parental beliefs and knowledge about dual language development and education survey
Creators: name: Davis-Hilton, Aniyah
Publisher: name: No Publisher Supplied

description: The rise in the preschool Dual Language Learner (DLL) population has led researchers to examine promising practices that contribute to dual language development. However, few studies have explored what parents of DLLs know about dual language development and education and whether their beliefs and knowledge are congruent with scientific findings. In the current study, an assessment tool, Knowledge about Dual Language and Education (KnDLE), was developed and piloted to understand parental beliefs and knowledge specific to dual language development and education. In addition, the associations between parental beliefs and knowledge and demographic factors were examined. There were 299 parents of DLLs aged 0 to 6 years. Cronbach’s alpha of KnDLE indicated a very good reliability (α = .808). The results indicated that parents showed strengths and misconceptions in their knowledge of dual language development and education. Additionally, higher English proficiency and immigrant status were associated with a greater level of parental beliefs and knowledge. However, parental income and educational level were not associated with parental dual language beliefs and knowledge. These findings highlight the need for interventions and parent education programs to build upon existing parental knowledge and address the misconceptions parents may hold.

description: Using lunar seismological data, constraints have been proposed on the available parameter space of macroscopic dark matter (macros). We show that actual limits are considerably weaker by considering in greater detail the mechanism through which macro impacts generate detectable seismic waves, which have wavelengths considerably longer than the diameter of the macro. We show that the portion of the macro parameter space that can be ruled out by current seismological evidence is considerably smaller than previously reported, and specifically that candidates with greater than or equal to nuclear density are not excluded by lunar seismology.

description: One of today’s most pressing challenges is to safeguard the loss of ecosystem biodiversity and functioning, while simultaneously allowing for their exploitation by those who depend on their services, goods and benefits. In Europe, Maritime Spatial Planning (MSP) is the main governance process to ideally integrate sustainability and exploitation. This requires tools and knowledge to align MSP and marine protected area (MPA) designation processes, which are lacking particularly regarding transboundary coordination and connectivity. MarinePlan will co-develop with stakeholders a Decision Support System (DSS) for ecosystem-based maritime spatial planning (EB-MSP) together with best practice guidance to enhance the effectiveness of spatial conservation and restoration measures for marine biodiversity in European Seas.

Ethical research underpins MarinePlan’s co-development approach and engagement with project participants. This document explains how MarinePlan will inform and recruit participants, obtain and record their informed consent, and collect, process and store their data. Templates of the participant information sheets and consent forms are attached in the Appendices. These documents have been submitted to Queen’s University Belfast’s (QUB) Faculty of Engineering and Physical Sciences Research Ethics Committee and a copy of their approval will be kept on file.
Weak Asymmetric Power and looser Coordination among Actors: Hurdles for the Ethiopia's Leather Industry Competitiveness

description: Though it is not equivalent to its potential, the leather industry in Ethiopia has been one of the key industries which support the special economic need of the nation called foreign currency generation, besides other economic benefits. Evidently, irrespective of the potential availability of relatively competitive resource base, cheap labor, policies and strategies, incentives as well as support institutions, the value captured by the core actors or individual firms and the export performance of the industry shows wider gap from the expectation mainly due to weak asymmetric power relation and looser coordination among different level of actors. But competitors, especially many emerging economies, have shifted their development strategies or business environment from simple export-oriented firm level thinking to an emphasis on gaining access to higher value adding strategies in global value chains. True, this necessitates systemic efficiency and competency of all actors along the value chain. Actually global value chain approach (VCA), as a method and development strategy, gives possibilities to appropriately analyze the efficiencies, competencies, opportunities and perhaps also the risks of the whole value chain and help forward the development or upgrading strategies so as to be globally competitive. In this respect, Ethiopia's leather value chain is characterized by very low supply of raw materials with poor quality, complex routes of input recovery, sluggish material flow with wider gap between end users expectations and producers' performance, very low value added, dysfunctional information flow, weakly exercising of governance functions and less coordination among macro-, meso- and micro-level actors along with some rivalry directions or policies. Thus, the immediate measures to be taken so as to make the sector competitive are to fill the gaps of those suboptimal value chain attributes and to reconcile and align those antagonistic directions and policies accordingly. Key Words: value chain, value added, governance, coordination, transaction cost, product flow, information flow, critical success factors, leverage points, benchmark, upgrading
Medienerziehung in der Unterstufe – eine Aufgabe für die Schulsozialarbeit? Eine Handlungsempfehlung für die Medienerziehung aus Sicht der Schulsozialarbeit

description: Kinder in der Schweiz wachsen mit Medien auf und werden früh mit deren Inhalten konfrontiert, was sie unter Umständen überfordern kann. Deshalb sind Schulsozialarbeitende gefordert, präventive und unterstützende Angebote für Kinder, Fachpersonen aus der Schule und Erziehungsberechtigte anzubieten. Die vorliegende Arbeit ist als Forschungsarbeit mit einem Theorieteil und der Durchführung und Auswertung von Leitfadeninterviews mit vier Fachpersonen der Schulsozialarbeit aufgebaut. Im Theorieteil werden Theorien über Medien im Zusammenhang mit Sozialisation, Erziehung, Nutzung und psychosozialem Verhalten erläutert sowie die Theorie der Schulsozialarbeit vorgestellt. Es wird untersucht, wie Schulsozialarbeitende im Kanton Zürich mit Unsicherheiten seitens Fachpersonen aus der Schule und Erziehungsberechtigten im Umgang mit der Mediennutzung und Medienerziehung von Kindern im Unterstufenalter umgehen. Weiter werden daraus Handlungsansätze und ein Auftrag für die Schulsozialarbeit abgeleitet. Es hat sich ergeben, dass die Schulsozialarbeitenden Verständnis dafür zeigen, dass die Thematik zuweilen überfordern und belasten kann. Jedoch ist auch ein gewisses Unverständnis für die mangelnde Kontrolle seitens der Erziehungsberechtigten erkennbar. Als Handlungsansatz für die SSA hat sich ergeben, dass Präventionsarbeit für Erziehungsberechtigte im Bereich der Aufklärung und Sensibilisierung angestrebt werden sollte. Der Auftrag besteht darin, über die Folgen der übermässigen Mediennutzung aufzuklären und Sensibilisierung und Aufklärung anzubieten. Weiter soll die Zusammenarbeit zwischen Elternhaus und Schule gefördert werden, um eine positive Entwicklung von Kindern und Jugendlichen anzustreben.

Model independent variance cancellation in CMB lensing cross-correlations

description: Cross-correlations of CMB lensing reconstructions with other tracers of matter constrain primordial non-Gaussianity, neutrino masses and structure growth as a function of cosmic time. We formalize a method to improve the precision of these measurements by using a third tracer to remove structure from the lensing reconstructions. Crucially, our method enjoys the variance reduction benefits of a joint-modelling approach without the need to model the cosmological dependence of the ancillary tracer. We present a first demonstration of variance cancellation using data from Planck and the DESI Legacy Surveys, showing a 10-20% reduction in both lensing power and cross-correlation variance using the Cosmic Infrared Background (CIB) or DESI Legacy Survey Luminous Red Galaxies (LRGs) as matter tracers.

Anisotropic molecular coarse-graining by force and torque matching with neural networks

description: We develop a machine-learning method for coarse-graining condensed-phase molecular systems using anisotropic particles. The method extends currently available high-dimensional neural network potentials by addressing molecular anisotropy. We demonstrate the flexibility of the method by parametrizing single-site coarse-grained models of a rigid small molecule (benzene) and a semi-flexible organic semiconductor (sexithiophene), attaining structural accuracy close to the all-atom models for both molecules at considerably lower computational expense. The machine-learning method of constructing the coarse-grained potential is shown to be straightforward and sufficiently robust to capture anisotropic interactions and many-body effects. The method is validated through its ability to reproduce the structural properties of the small molecule's liquid phase and the phase transitions of the semi-flexible molecule over a wide temperature range.

Energy saving mechanisms, collective behavior and the variation range hypothesis in biological systems: A review

description: Energy saving mechanisms are ubiquitous in nature. Aerodynamic and hydrodynamic drafting, vortice uplift, Bernoulli suction, thermoregulatory coupling, path following, physical hooks, synchronization, and cooperation are only some of the better-known examples. While drafting mechanisms also appear in non-biological systems such as sedimentation and particle vortices, the broad spectrum of these mechanisms appears more diversely in biological systems including bacteria, spermatozoa, various aquatic species, birds, land animals, semi-fluid dwellers like turtle hatchlings, as well as human systems. We present the thermodynamic framework for energy saving mechanisms, and we review evidence in favor of the variation range hypothesis. This hypothesis posits that, as an evolutionary process, the variation range between strongest and weakest group members converges on the equivalent energy saving quantity that is generated by the energy saving mechanism. We also review self-organized structures that emerge due to energy saving mechanisms, including convective processes that can be observed in many systems over both short and long time scales, as well as high collective output processes in which a form of collective position locking occurs.
