description: We have studied the island size distribution and spatial correlation function of an island growth model under the effect of an elastic interaction of the form $1/r^{3}$. The mass distribution $P_n(t)$ that was obtained presents a pronounced peak that widens with the increase of the total coverage of the system, $θ$. The presence of this peak is an indication of the self-organization of the system, since it demonstrates that some sizes are more frequent than others. We have treated exactly the energy of the system using periodic boundary conditions which were used in the Monte-Carlo simulations. A discussion about the effect of different factors is presented.

description: Purpose: Speech-language pathologists may introduce augmentative or alternative communication (AAC) systems to people who are unable to use speech for everyday communication. Despite the benefits of AAC systems, they are significantly underutilized by the people with complex communication needs. The current review aimed to synthesize the barriers and facilitators to the provision and use of low-tech and unaided AAC systems. Materials and methods: Relevant literature was identified via a systematic search strategy. Included articles (n = 43) were evaluated using the Critical Appraisal Skills Programme. Qualitative framework analysis was then completed with reference to the International Classification of Functioning, Disability, and Health (ICF). Results and conclusion: Most barriers and facilitators were coded as contextual factors within the ICF. Of most prominence were environmental factors, including attitudes of and supports provided by professionals, family members, and the society at large. Themes were also identified which related to the personal factors, including the user’s own attitude, socioeconomic status, and culture. Beyond these contextual factors, the remaining codes related to body functions such as cognition and movement. There are numerous barriers to the provision and use of low-tech and unaided AAC systems, which may contribute to the inadequate use of these systems by people with complex communication needs. Suggestions for reducing these barriers are presented with regards to the person with complex communication needs, their family, and the professionals involved in their care.Implications for RehabilitationAAC systems can reduce participation restrictions for people with complex communication needs.The provision and use of AAC systems is influenced by environmental factors, personal factors, and features of a person’s body function.SLPs may need to collaborate with a large multidisciplinary team to successfully introduce AAC systems.SLP, teaching, and nursing students require theoretical and practical experience in AAC throughout their training to enable the provision and use of these systems.

18F

description: Abstract: Purpose: Phantoms are routinely used in molecular imaging to assess scanner performance. However, traditional phantoms with fillable shapes do not replicate human anatomy. 3D-printed phantoms have overcome this by creating phantoms which replicate human anatomy which can be filled with radioactive material. The problem with these is that small objects suffer to a greater extent than larger objects from the effects of inactive walls, and therefore, phantoms without these are desirable. The purpose of this study was to explore the feasibility of creating resin-based 3D-printed phantoms using 18F. Methods: Radioactive resin was created using an emulsion of printer resin and 18F-FDG. A series of test objects were printed including twenty identical cylinders, ten spheres with increasing diameters (2 to 20 mm), and a double helix. Radioactive concentration uniformity, printing accuracy and the amount of leaching were assessed. Results: Creating radioactive resin was simple and effective. The radioactive concentration was uniform among identical objects; the CoV of the signal was 0.7% using a gamma counter. The printed cylinders and spheres were found to be within 4% of the model dimensions. A double helix was successfully printed as a test for the printer and appeared as expected on the PET scanner. The amount of radioactivity leached into the water was measurable (0.72%) but not visible above background on the imaging. Conclusions: Creating an 18F radioactive resin emulsion is a simple and effective way to create accurate and complex phantoms without inactive walls. This technique could be used to print clinically realistic phantoms. However, they are single use and cannot be made hollow without an exit hole. Also, there is a small amount of leaching of the radioactivity to take into consideration.

description: In society, mutual cooperation, defection, and asymmetric exploitative relationships are common. Whereas cooperation and defection are studied extensively in the literature on game theory, asymmetric exploitative relationships between players are little explored. In a recent study, Press and Dyson demonstrate that if only one player can learn about the other, asymmetric exploitation is achieved in the prisoner's dilemma game. In contrast, however, it is unknown whether such one-way exploitation is stably established when both players learn about each other symmetrically and try to optimize their payoffs. Here, we first formulate a dynamical system that describes the change in a player's probabilistic strategy with reinforcement learning to obtain greater payoffs, based on the recognition of the other player. By applying this formulation to the standard prisoner's dilemma game, we numerically and analytically demonstrate that an exploitative relationship can be achieved despite symmetric strategy dynamics and symmetric rule of games. This exploitative relationship is stable, even though the exploited player, who receives a lower payoff than the exploiting player, has optimized the own strategy. Whether the final equilibrium state is mutual cooperation, defection, or exploitation, crucially depends on the initial conditions: Punishment against a defector oscillates between the players, and thus a complicated basin structure to the final equilibrium appears. In other words, slight differences in the initial state may lead to drastic changes in the final state. Considering the generality of the result, this study provides a new perspective on the origin of exploitation in society.

description: We consider the Kerr-de Sitter (Kerr-dS) black hole in various dimensions. Introducing a counterterm, we show that the total action of these spacetimes are finite. We compute the masses and the angular momenta of Kerr-dS spaces with one rotational parameter in four, five and seven dimensions. These conserved charges are also computed for the case of Kerr-dS space with two rotational parameters in five dimensions. Although the angular momentum density due to the counterterm is nonzero, it gives a vanishing contribution to the total angular momentum. We also find that the total angular momentum of the spacetime is independent of the radius of the boundary for all cases, a fact that is not true for the total mass of the system.

description: We present ALMA observations of the CO(2-1) and CO(3-2) molecular gas transitions and associated (sub)-mm continua of the nearby Seyfert 1.5 galaxy NGC3227 with angular resolutions 0.085-0.21" (7-15pc). On large scales the cold molecular gas shows circular motions as well as streaming motions on scales of a few hundred parsecs associated with a large scale bar. We fitted the nuclear ALMA 1.3mm emission with an unresolved component and an extended component. The 850$μ$m emission shows at least two extended components, one along the major axis of the nuclear disk and the other along the axis of the ionization cone. The molecular gas in the central region (1" ~73pc) shows several CO clumps with complex kinematics which appears to be dominated by non-circular motions. While we cannot demonstrate conclusively the presence of a warped nuclear disk, we also detected non-circular motions along the kinematic minor axis. They reach line-of-sight velocities of v-vsys =150-200km/s. Assuming that the radial motions are in the plane of the galaxy, then we interpret them as a nuclear molecular outflow due to molecular gas in the host galaxy being entrained by the AGN wind. We derive molecular outflow rates of $5\,M_\odot\,{\rm yr}^{-1}$ and $0.6\,M_\odot\,{\rm yr}^{-1}$ at projected distances of up to 30pc to the northeast and southwest of the AGN, respectively. At the AGN location we estimate a mass in molecular gas of $5\times 10^{5}\,M_\odot$ and an average column density $N({\rm H}_2) = 2-3\times 10^{23}\,{\rm cm}^{-2}$ in the inner 15pc. The nuclear molecular gas and sub-mm continuum emission of NGC3227 do not resemble the classical compact torus. Rather, these emissions extend for several tens of parsecs and appear connected with the circumnuclear ring in the host galaxy disk, as found in other local AGN. (Abridged)

title: Local Interaction Region Coupling Correction for the LHC
Creators: name: Soubelet, Felix
Publisher: name: University of Liverpool Repository
Year: 2024

description: In order to further expand our knowledge of the structure of matter and the workings of our universe, scientists are constantly seeking to collide particles at ever-increasing energies and with higher luminosity. So is the task of the Large Hadron Collider (LHC) at CERN, the highest energy particle accelerator and collider to date, and the goal of its future upgrade into the High-Luminosity Large Hadron Collider (HL-LHC). This constant progress in performance requires more intense beams and smaller beam sizes at collisions points as well as a tight control of these parameters. Thus, successful operation of large-scale particle colliders heavily depends on the precise correction of magnet field or alignment errors present in the machine.

In the LHC, transverse betatron coupling has been shown to have a significant impact on both the beam dynamics and luminosity production due to uncompensated sources close to the Interaction Points (IPs). However, current measurement methods are not sufficient for precise local coupling measurement at the IP, and the impact of these sources has so far been left uncompensated. This thesis covers work done in an effort to determine and correct Interaction Region (IR) local coupling.

A key tool presented in this document is the designed Rigid Waist Shift (RWS), a new optics configuration which allows the determination of local coupling corrections based on correlated global variables such as the closest tune approach |C−|. The validity of this new method has been demonstrated through simulations and experimental measurements taken during the LHC Run 3 commissioning in 2022, where determined corrections were applied and led to a measured luminosity increase of 9.7 % and 3.5 % at the ATLAS and CMS detectors, respectively. Additionally, the application of machine learning techniques for high complexity problems such as the detection of coupling sources in the LHC has been explored, yielding promising results but requiring some more improvements to be operationally viable. Finally, optics studies which revealed avenues for improvements in the optics measurements done at the LHC are also presented.

 Macrostemum centrotum Navás, 1917: 403 [Holotype male; Vietnam (Sapa)].
 Diagnosis. Male. Antennae 30 mm in length. Antennal flagellum first few segments darker brown then lighter throughout with darker striations. Forewing 13 mm and hindwing 9 mm in length. Mesoscutum and mesoscutellum without evident markings. Tibial spurs 2.4.4.
 Male genitalia. Inferior appendages two-segmented (Fig. 61). In lateral view, with protrusion in phallus apex (Fig. 63). In lateral view, segment X broad narrowing towards the apex (Fig. 61), in dorsal view bifid and each lobe blunt (Fig. 62).
 Female. Antennae broken. Antennal flagellum same colouration as male. Forewing 10 mm and hindwing 7 mm in length. Mesoscutum and mesoscutellum without evident markings. Tibial spurs 2.4.4.
 Material examined. Vietnam: 3 males, 4 females, Tam Dao, coll. H. Malicky, 19 May–13 June 1995 (HMPC).
 Distribution. China, Vietnam.
 Remarks. The original description of Navás (1917) (in Latin) did not provide illustration, as well as information on the deposition of the specimen. The assumption is that the type specimen might be deposited in the Natural History Museum in Barcelona, Spain where his personal collections were transferred from the Catholic boy’s school (John Morse, personal communication). However, the museum curator confirmed that there are no species from the genus Macrostemum in their list of available type specimen collection by Navás (Glòria Masó Ros, personal communication). The curator also stated that there is a necessity to review the general collection and not types by Navás but the person handling the collection is now on leave. Therefore, the actual status of the type material cannot be confirmed and the possibility that it is also lost can be considered. Malicky (1998b) redescribed the male of this species including the illustrations of genitalia and forewing. The wing patterns of all the examined specimens were consistent (Fig. 60).

description: We examine stochastic maps in the context of quantum optics. Making use of the master equation, the damping basis, and the Bloch picture we calculate a non-unital, completely positive, trace-preserving map with unequal damping eigenvalues. This results in what we call the squeezed vacuum channel. A geometrical picture of the effect of stochastic noise on the set of pure state qubit density operators is provided. Finally, we study the capacity of the squeezed vacuum channel to transmit quantum information and to distribute EPR states.

description: A wide range of fundamental machine learning tasks that are addressed by the maximum a posteriori estimation can be reduced to a general minimum conical hull problem. The best-known solution to tackle general minimum conical hull problems is the divide-and-conquer anchoring learning scheme (DCA), whose runtime complexity is polynomial in size. However, big data is pushing these polynomial algorithms to their performance limits. In this paper, we propose a sublinear classical algorithm to tackle general minimum conical hull problems when the input has stored in a sample-based low-overhead data structure. The algorithm's runtime complexity is polynomial in the rank and polylogarithmic in size. The proposed algorithm achieves the exponential speedup over DCA and, therefore, provides advantages for high dimensional problems.

Object recognition
Semantic memory
Concepts
Memory

description: Abstract: Humans have a remarkable fidelity for visual long-term memory, and yet the composition of these memories is a longstanding debate in cognitive psychology. While much of the work on long-term memory has focused on processes associated with successful encoding and retrieval, more recent work on visual object recognition has developed a focus on the memorability of specific visual stimuli. Such work is engendering a view of object representation as a hierarchical movement from low-level visual representations to higher level categorical organization of conceptual representations. However, studies on object recognition often fail to account for how these high- and low-level features interact to promote distinct forms of memory. Here, we use both visual and semantic factors to investigate their relative contributions to two different forms of memory of everyday objects. We first collected normative visual and semantic feature information on 1,000 object images. We then conducted a memory study where we presented these same images during encoding (picture target) on Day 1, and then either a Lexical (lexical cue) or Visual (picture cue) memory test on Day 2. Our findings indicate that: (1) higher level visual factors (via DNNs) and semantic factors (via feature-based statistics) make independent contributions to object memory, (2) semantic information contributes to both true and false memory performance, and (3) factors that predict object memory depend on the type of memory being tested. These findings help to provide a more complete picture of what factors influence object memorability. These data are available online upon publication as a public resource.

AbstractLusutrombopag (Mulpleta®), an orally bioavailable, small molecule thrombopoietin receptor agonist, is approved for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. In placebo-controlled phase 3 clinical trials, lusutrombopag significantly increased the proportion of patients who did not require a platelet transfusion prior to the procedure or rescue therapy for bleeding up to 7 days after the scheduled procedure. Lusutrombopag also significantly increased the proportion of patients who were responders (i.e. had a platelet count ≥ 50 x 109/L and an increase of ≥ 20 x 109/L from baseline) compared with placebo. Lusutrombopag is well tolerated, with headache being the most common adverse reaction in lusutrombopag recipients in clinical trials. Thus, lusutrombopag represents a promising emerging therapeutic option for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure.© Springer Nature Switzerland AG 2019

 Remarks. Coralliophaga coralliophaga has rarely been found on Rodrigues probably due to its inaccessible habitat (coral crevices) rather than any true rarity. Juvenile shells (figure 145) lack the radial and lamellose sculpture that develops in the adult (figure 146). Similar juvenile shells, from marine caves, were described by Hayami and Kase (1993) as a new species, Coralliophaga hyalina. We could not attribute any of the Rodrigues material to species other than C. coralliophaga.

description: The ultra-strong light-matter coupling regime has been demonstrated in a novel three-dimensional inductor-capacitor (LC) circuit resonator, embedding a semiconductor two-dimensional electron gas in the capacitive part. The fundamental resonance of the LC circuit interacts with the intersubband plasmon excitation of the electron gas at $ω_c = 3.3$~THz with a normalized coupling strength $2Ω_R/ω_c = 0.27$. Light matter interaction is driven by the quasi-static electric field in the capacitors, and takes place in a highly subwavelength effective volume $V_{\mathrm{eff}} = 10^{-6}λ_0^3$ . This enables the observation of the ultra-strong light-matter coupling with $2.4\times10^3$ electrons only. Notably, our fabrication protocol can be applied to the integration of a semiconductor region into arbitrary nano-engineered three dimensional meta-atoms. This circuit architecture can be considered the building block of metamaterials for ultra-low dark current detectors.

description: An optimal single-photon source should deterministically deliver one and only one photon at a time, with no trade-off between the source's efficiency and the photon indistinguishability. However, all reported solid-state sources of indistinguishable single photons had to rely on polarization filtering which reduced the efficiency by 50%, which fundamentally limited the scaling of photonic quantum technologies. Here, we overcome this final long-standing challenge by coherently driving quantum dots deterministically coupled to polarization-selective Purcell microcavities--two examples are narrowband, elliptical micropillars and broadband, elliptical Bragg gratings. A polarization-orthogonal excitation-collection scheme is designed to minimize the polarization-filtering loss under resonant excitation. We demonstrate a polarized single-photon efficiency of 0.60+/-0.02 (0.56+/-0.02), a single-photon purity of 0.975+/-0.005 (0.991+/-0.003), and an indistinguishability of 0.975+/-0.006 (0.951+/-0.005) for the micropillar (Bragg grating) device. Our work provides promising solutions for truly optimal single-photon sources combining near-unity indistinguishability and near-unity system efficiency simultaneously.

description: The system of N particles moving on a circle and interacting via a global repulsive cosine interaction is well known to display spatially inhomogeneous structures of extraordinary stability starting from certain low energy initial conditions. The object of this paper is to show in a detailed manner how these structures arise and to explain their stability. By a convenient canonical transformation we rewrite the Hamiltonian in such a way that fast and slow variables are singled out and the canonical coordinates of a collective mode are naturally introduced. If, initially, enough energy is put in this mode, its decay can be extremely slow. However, both analytical arguments and numerical simulations suggest that these structures eventually decay to the spatially uniform equilibrium state, although this can happen on impressively long time scales. Finally, we heuristically introduce a one-particle time dependent Hamiltonian that well reproduces most of the observed phenomenology.

description: Active optical systems can give rise to intriguing phenomena and applications that are not available in conventional passive systems. Structural rotation has been widely employed to achieve non-reciprocity or time-reversal symmetry breaking. Here, we examine the quasi-normal modes and scattering properties of a two-dimensional cylindrical cavity under rotation. In addition to the familiar phenomenon of Sagnac frequency shift, we observe the the hybridization of the clockwise(CW) and counter-clockwise(CCW) chiral modes of the cavity controlled by the rotation. The rotation tends to suppress one chiral mode while amplify the other, and it leads to the variation of the far field. The phenomenon can be understood as the result of a synthetic gauge field induced by the rotation of the cylinder. We explicitly derived this gauge field and the resulting Sagnac frequency shift. The analytical results are corroborated by finite element simulations. Our results can be applied in the measurement of rotating devices by probing the far field.

Brownian motion with alternately fluctuating diffusivity: Stretched-exponential and power-law relaxation

description: We investigate Brownian motion with diffusivity alternately fluctuating between fast and slow states. We assume that sojourn-time distributions of these two states are given by exponential or power-law distributions. We develop a theory of alternating renewal processes to study a relaxation function which is expressed with an integral of the diffusivity over time. This relaxation function can be related to a position correlation function if the particle is in a harmonic potential, and to the self-intermediate scattering function if the potential force is absent. It is theoretically shown that, at short times, the exponential relaxation or the stretched-exponential relaxation are observed depending on the power law index of the sojourn-time distributions. In contrast, at long times, a power law decay with an exponential cutoff is observed. The dependencies on the initial ensembles (i.e., equilibrium or non-equilibrium initial ensembles) are also elucidated. These theoretical results are consistent with numerical simulations.

description: Unanticipated events can cause considerable economic hardship for poor rural households. Some types of negative shocks, for example weather-related agricultural losses and vector-borne diseases, are expected to occur more frequently as a result of climate change. This paper measures the role of household- and location-specific characteristics in conditioning behavioral responses to idiosyncratic and covariate shocks. We use data from more than 8000 households in 25 developing countries, compiled in the global database of the Poverty Environment Network (PEN). We employ a hierarchical multinomial logit model to identify the importance of characteristics observed at different levels of aggregation on a set of responses to economic shocks. Results indicate that in response to idiosyncratic shocks, households tend to deplete financial and durable assets, whereas covariate shocks predominantly result in reduced consumption. Households in sites characterized by high asset wealth tend to respond to shocks more proactively than in sites with average or below average asset wealth; savings emerge as an important determinant of shock response behavior at the household level. We also find that a higher concentration of land ownership at the village level reduces the prevalence of natural resource-based coping strategies. Overall, rural households are less reliant on natural resource extraction for coping than expected from the case-study literature. Our findings have implications for rural development and climate change adaptation strategies.
Russia’s Intervention in Ukraine - A Neoclassical Realist Analysis

description: This thesis aims to undertake a thorough analysis of Russia’s foreign policy behaviour vis-à-vis Ukraine and the political events that unfolded after the Euromaidan uprising in late 2013 and 2014 through a neoclassical realist perspective. By means of deductive theory-testing, the objective of this paper is to derive and later test the hypothesis that neoclassical realist theory provides as a soft-positivistic approach sufficient explanatory power for the Kremlin’s crisis decision-making, foreign policy action and grand strategic adjustment choices after the ousting of the former Ukrainian president Viktor Yanukovych and the further course of events until this day. The methodology hereby used is comprised of a qualitative case study analysis and the process-tracing method. I will argue that the domestic-level intervening variables of leader images, strategic culture, state-society relations and domestic institutions have a significant, yet varying influence on how the systemic stimuli stemming from the international system are perceived, processed and subsequently transformed into external action by the Russian foreign policy elite. The Russian foreign policy behaviour as the dependent variable is hereby analysed on the basis of military doctrine and new means of warfare, diplomatic activities and the strategic use of norms and international law, economic and trade policies and, finally, domestic resource extraction. The paper’s findings show that the Russian case example boldly demonstrates how – besides the influence of systemic stimuli stemming from the international structure – leader images and strategic culture occupy an important position in the equation of causal factors, while state-society relations and domestic institutions turn out to lack strong relevance due to their state of consensus and marginalisation for explaining and understanding Russia’s foreign policy behaviour vis-à-vis Ukraine.

 Description. Small hyaline valves with a rhomboidal outline and carinate posterior slope; posterior area with a fine scabrous sculpture. The hinge (figure 151) is very similar in form to that of Coralliophaga (figure 147).
 Remarks. It is most likely that these valves represent juveniles of a trapeziid and probably Glossocardia obesa (Reeve, 1843). This is the only trapeziid so far found at Rodrigues and the scabrous sculpture and carinate posterior are shared with the juveniles described above.

description: Linear optical computing (LOC) with thermal light has recently gained attention because the problem is connected to the permanent of a Hermitian positive semidefinite matrix (HPSM), which is of importance in the computational complexity theory. Despite the several theoretical analyses on the computational structure of an HPSM in connection to LOC, the experimental demonstration and the computational complexity analysis via the linear optical system have not been performed yet. We present, herein, experimental LOC for estimating the permanent of an HPSM. From the linear optical experiments and theoretical analysis, we find that the LOC efficiency for a multiplicative error is dependent on the value of the permanent and that the lower bound of the computation time scales exponentially. Furthermore, our results are generalized and applied to LOC of permanents of unitary matrices, which can be implemented with a multi-port quantum interferometer involving single-photons at the input ports. We find that LOC with single-photons, for the permanent estimation, is on average less efficient than the most efficient classical algorithm known to date, even in ideal conditions.

description: This paper addresses the issue of price risk assessment in the agricultural commodity markets. Four the most frequently used approaches and related methods of measuring price risk in commodity markets were characterized and used to assess price risk in the wheat market in Poland. Results of the analysis showed that predictable and unpredictable components of the price series should be distinguished to properly evaluate real risk exposure. Some noticeable changes in the volatility of the wheat prices over the analyzed period indicate that exposure to the price risk in Polish wheat market after accession to the EU has increased.
