description: We present the redshift evolutions and distributions of the gamma-ray luminosity and photon spectral index of flat spectrum radio quasar (FSRQ) type blazars, using non-parametric methods to obtain the evolutions and distributions directly from the data. The sample we use for analysis consists of almost all FSRQs observed with a greater than approximately 7 sigma detection threshold in the first year catalog of the Fermi Gamma-ray Space Telescope's Large Area Telescope, with redshfits as determined from optical spectroscopy by Shaw et al. We find that FSQRs undergo rapid gamma-ray luminosity evolution, but negligible photon index evolution, with redshift. With these evolutions accounted for we determine the density evolution and luminosity function of FSRQs, and calculate their total contribution to the extragalactic gamma-ray background radiation, resolved and unresolved, which is found to be 16(+10/-4)%, in agreement with previous studies.

Novel feather fibre textiles: designing a circular economy for waste feathers
Creators: name: Dieckmann, Elena Maxine
Publisher: name: Imperial College London
Year: 2020

description: Poultry consumption is increasing globally and approximately 3.1 million tonnes of waste feathers are currently produced per annum in the EU. As a result, research investigating novel applications of waste feathers is increasing. Feathers have high tensile strength and toughness, extremely low density, excellent thermal insulating properties, hydrophobicity and are biodegradable. This research aimed to develop a feather waste conversion process that could produce new feather- derived materials containing high levels of feathers. The research has developed a new way of converting feathers that uses readily available industrial processes. Abstract The manufacturing method developed involves producing feather fibres followed by airlaid textile processing. This produces lightweight thermally insulating feather fibre materials. Producing nonwoven textiles from feather fibres allows the thermal insulating properties of feathers to be exploited and these have the potential to replace synthetic, non-biodegradable and non-renewable materials used in a range of applications. A large variety of nonwoven feather mats were manufactured, characterised and tested. Thermal insulation packaging was identified as the most appropriate product for nonwoven feather textiles. A thermally insulating feather-based packaging product (pluumo) was developed and a spin-out company (Aeropowder) was formed to commercially exploit the product concept. Despite the excellent thermal performance of pluumo, the economic and environmental viability is uncertain because of the costs associated with washing and transporting waste feathers. This led to an assessment methodology to identify barriers to transitioning end-of-life materials into a circular economy. Applying the methodology to waste feathers showed that significant barriers exist including the need to develop commercially viable feather washing technologies. The research demonstrates a new and potentially commercially viable process that produces materials that exploit the properties of waste feathers. New knowledge is associated with understanding the detailed processing requirements for feather textiles formed which can be used as sustainable thermal packaging.
Anomalous Power Law Decay in Solvation Dynamics of DNA: A Mode Coupling Theory Analysis of Ion Contribution

description: Several time domain fluorescence Stokes shift (TDFSS) experiments have reported a slow power law decay in the hydration dynamics of a DNA molecule. Such a power law has neither been observed in computer simulations nor in some other TDFSS experiments. Here we observe that a slow decay may originate from collective ion contribution because in experiments DNA is immersed in a buffer solution, and also from groove bound water and lastly from DNA dynamics itself. In this work we first express the solvation time correlation function in terms of dynamic structure factors of the solution. We use mode coupling theory to calculate analytically the time dependence of collective ionic contribution. A power law decay in seen to originate from an interplay between long range probe-ion direct correlation function and ion-ion dynamic structure factor. Although the power law decay is reminiscent of Debye-Falkenhagen effect yet solvation dynamics is dominated by ion atmosphere relaxation times at longer length scales (small wave number) than in electrolyte friction. We further discuss why this power law may not originate from water motions which have been computed by molecular dynamics simulations. Lastly, we propose several experiments to check the prediction of the present theoretical work.

description: This workshop will introduce CHMap, an open-access web GIS platform developed by the Max Planck Institute for the History of Science (MPIWG) and Shanghai Jiao Tong University (SJTU), to researchers in Chinese and East Asian history and digital humanities. CHMap provides large-scale, geo-referenced land survey maps of China produced in the late nineteenth and early twentieth centuries as base layers via Web Map Tile Service (WMTS). It allows researchers to integrate image collections from other sources on top of those base layers for exploratory and comparative analyses. From the last decades of the Qing dynasty to the end of the Republican era in 1949, China’s central and provincial governments, as well as the Japanese Army, conducted geographic surveys across the country and produced maps containing detailed information on topographical and administrative features. As the earliest maps made with modern cartographic techniques in China, they offer a panoramic view of "the last images of imperial China" with broad coverage of the country’s major cities and counties. Over 4,000 of these land survey maps of China were compiled and published by the Japanese publisher Kagaku Shoin between 1986 and 1998. MPIWG’s Department III and SJTU’s Department of History have jointly curated, digitized, and geo-referenced these maps into WMTS layers to create CHMap, which provides them as scalable base layers to be used within and across external GIS platforms and clients. In addition, CHMap helps researchers to "link visions together" by providing a digital ecosystem to geo-reference and visualize external image collections together with its base layers. Image collections from IIIF servers, CSV and GeoJSON datasets, and other WMTS layers could all be imported into CHMap. For example, we have built a route to display images from Chinese local gazetteers via MPIWG’s LoGaRT, and we will demonstrate how researchers could analyze and compare their images collectively in CHMap. After this workshop, participants will be able to use CHMap to investigate images together with data of various sources and formats. Besides researchers, we also welcome librarians and tool developers who are interested in GIS- and image-based content integration in order to foster discussion, innovation, and communication across digital humanities.
The effect of the GLP-1 agonist, liraglutide, on the right ventricle in pulmonary hypertension
Creators: name: Zhao, Lin
Publisher: name: Imperial College London
Year: 2020

description: Right ventricular (RV) function is the major determinant of prognosis in pulmonary hypertension (PH) and dysregulated myocardial metabolism is a prominent feature of RV dysfunction. Glucagon-like peptide-1 (GLP-1) is one of the incretin hormones that potentiates insulin secretion and reduces glucagon release. Recent studies have shown that GLP-1 agonist liraglutide, an approved diabetes treatment, reduces the risk of heart failure in diabetes patients and improves pulmonary endothelial function in PH rats. My PhD project hypothesized that liraglutide is an emerging PH treatment, aiming to define its effects on RV function. I established cardiac magnetic resonance imaging (MRI) as a key translational tool to characterize the RV functional and structural remodelling, especially the RV uncoupling features, employing monocrotaline (MCT) and Sugen hypoxia (SuHx) PH models, along the course of PH development, together with pathological and molecular assessment. In both MCT and SuHx rats, treatment with liraglutide attenuated pulmonary artery pressure and pulmonary remodelling. Importantly, I demonstrated that liraglutide reversed the MCT or SuHx induced RV structural and functional remodelling by MRI cine, T1 mapping and gadolinium-enhanced scans. Moreover, pathological examination indicated that liraglutide reduced cardiac fibrosis and cardiomyocyte hypertrophy, as well as capillary rarefaction. Further study using the pulmonary artery banding mice validated and confirmed the direct effect of liraglutide on the RV. I examined the molecular pathways involved in RV remodelling that are impacted by liraglutide using RNA sequencing. Data from the PAB and SuHx models indicated the important involvement of liraglutide in the regulation of PI3K-Akt and AMPK pathways. My PhD project presented important preclinical evidence that liraglutide saves RV structural and functional remodelling in PH by modulating the cardiac metabolic homeostasis in addition to its pulmonary effects, supporting liraglutide as a potential future therapeutic option for PH patients.
End-functionalised polyethylenes: towards improved degradability of polyolefins
Creators: name: Von Goetze, Richard
Publisher: name: Imperial College London
Year: 2020

description: Since the 1950s, the global production of polymers has exponentially increased, particularly driven by polyolefins, now reaching over 400 million tons. As more polyolefins have been produced, the amount of waste generated from these has increased, specifically in single-use packaging materials. This thesis investigates a novel route to end-functionalised polyethylenes and di-block copolymers including a polyethylene block with the aim to improve the biodegradability of the most frequently used polyolefin. Chapter 1 introduces the subject of pro-degradants for plastics, as well as the economical background and commercial significance of polyolefins. Chapter 2 and 3 show the versatile functionalisation reactions that can be conducted starting from a di-alkyl zinc species in which each alkyl chain is HDPE (up to 68 carbons per HDPE chain). Functionalisation includes different halide end-groups (iodine and bromine with up to 99% functionalisation) and a terminal hydroxy functionalisation (with up to 78% functionalisation). Chapter 4 investigates the use of hydroxy end-functionalised HDPE chains as macroinitiators for the nucleophilic ring-opening polymerisation of rac-lactide, leading to the controlled synthesis and characterisation of five PE-PLA di-block copolymers in different wblock compositions. The synthesis of polyethylene-polycaprolactone di-block copolymers was attempted (PE-PCL), but did not result in a controlled synthesis. PE-PLA di-block copolymers were further studied regarding their thermal- and degradation behaviour. The PLA-block degraded under humid conditions, leaving an unchanged PE-block behind. Chapter 5 investigates the use of iodo-terminated polyethylene as a pro-degradant and as a potential UV-indicator for polyolefins. Chapter 6 provides additional data acquired within the course of this thesis to the reader.
Dark state lasers

description: We propose a new type of laser resonator based on imaginary "energy-level splitting" (imaginary coupling, or quality factor Q splitting) in a pair of coupled microcavities. A particularly advantageous arrangement involves two microring cavities with different free-spectral ranges (FSRs) in a configuration wherein they are coupled by "far-field" interference in a shared radiation channel. A novel Vernier-like effect for laser resonators is designed where only one longitudinal resonant mode has a lower loss than the small signal gain and can achieve lasing while all other modes are suppressed. This configuration enables ultra-widely tunable single-frequency lasers based on either homogeneously or inhomogeneously broadened gain media. The concept is an alternative to the common external cavity configurations for achieving tunable single-mode operation in a laser. The proposed laser concept builds on a high-Q "dark state" that is established by radiative interference coupling and bears a direct analogy to parity-time (PT) symmetric Hamiltonians in optical systems. Variants of this concept should be extendable to parametric-gain based oscillators, enabling use of ultrabroadband parametric gain for widely tunable single-frequency light sources.

description: Photomultipliers are commonly used in commercial PET scanner as devices which convert light produced in scintillator by gamma quanta from positron-electron annihilation into electrical signal. For proper analysis of obtained electrical signal, a photomultiplier gain curve must be known, since gain can be significantly different even between photomultipliers of the same model. In this article we describe single photoelectron method used for photomultipliers calibration applied for J-PET scanner, a novel PET detector being developed at the Jagiellonian University. Description of calibration method, an example of calibration curve and gain of few R4998 Hamamatsu photomultipliers are presented.

description: This research study employed a rigorous analysis of data to investigate the relationships between strategic management, international trade liberalization, and national growth in Libya. The research objectives were achieved through a comprehensive examination of the collected data, utilizing various statistical techniques. The initial phase of the analysis involved assessing the reliability of the questionnaire used in the study. Cronbach's alpha yielded an excellent internal consistency score of \(alpha = 0.91 \), affirming the reliability of the questions related to strategic management. Pearson's correlation coefficient was employed to measure the strength and direction of associations between variables. The findings revealed a statistically significant and moderately positive linear relationship (\( r = 0.404 \), p < 0.001) between strategic management and the liberalization of trade in Libya. Moreover, a statistically significant association (\( r = 0.145 \), p = 0.039) was identified between the liberalization of trade and national growth, further emphasizing the impact of trade policies on the nation's development. In summary, this study provides valuable insights into the interplay between strategic management, international trade, and national growth in Libya. The results indicate that strategic management plays a crucial role in shaping trade policies and, consequently, influencing the country's economic growth. These findings have important implications for policymakers and business leaders seeking to enhance Libya's economic prosperity in the context of globalization.

description: Motivated by the recently observed sublattice asymmetry of substitutional nitrogen impurities in CVD grown graphene, we show, in a mathematically transparent manner, that oscillations in the local density of states driven by the presence of substitutional impurities are responsible for breaking the sublattice symmetry. While these oscillations are normally averaged out in the case of randomly dispersed impurities, in graphene they have either the same, or very nearly the same, periodicity as the lattice. As a result, the total interaction energy of randomly distributed impurities embedded in the conduction-electron-filled medium does not vanish and is lowered when their configuration is sublattice-asymmetric. We also identify the presence of a critical concentration of nitrogen above which one should expect the sublattice asymmetry to disappear. This feature is not particular to nitrogen dopants, but should be present in other impurities.

The injury biomechanics of the pelvis in under-body blast conditions
Creators: name: Pandelani, Thanyani Abson
Publisher: name: Imperial College London
Year: 2020

description: In recent conflicts, blast injury from landmines and improvised explosive devices (IEDs) has been the main mechanism of wounding and death. When a landmine or IED detonates under a vehicle, (an under-body blast), the seat acceleration rapidly transmits a high load to the pelvis of the occupants, resulting in torso and pelvic fracture. Pelvic fractures have high a mortality rate, yet their injury mechanism has been poorly researched. This thesis seeks to advance the understanding of the pelvic injury mechanism of vehicle occupants and to quantify the loading environment at the vehicle seat due to under-body blast. This deeper understanding will lead to better protection and mitigation of injury and death. An analysis of seat accelerations from live-fire vehicle experiments was conducted and the loading envelope was developed. Cadaveric tests were conducted using loading conditions within the envelope to explore the mechanism of pelvic injury. In this thesis, a FE model of the pelvis was developed and compared with data from the cadaveric experiments. The material behaviour of the adipose tissue of the buttocks was deemed crucial to the biofidelity of the FE model, so experimental characterisation was conducted. Tests were performed on cadaveric adipose tissue and an algorithm was developed and used to calculate the non-linear viscoelastic material properties of the human adipose tissue. The material properties will results in better response of the model and understanding of pelvic injuries in UBB events. A validated 2D model of the pelvis was then used to quantify mitigation technologies. Three foams that can be applied in seats were tested virtually, and all showed variable levels of reduction of the load transmitted to the pelvis. The findings of this thesis offer deeper insight into the mechanics of pelvic injuries. Researchers and vehicle designers can use the findings and the tools developed in this thesis to facilitate the development of vehicle and seat design for survivability.

description: In this paper we examined the impact of the quality of teacher-student relationships at age 10 on young people's delinquency at ages 13, 15, and 17 utilizing propensity-score matching. The young people were matched based on 105 characteristics, measured at ages 7 to 10. The sample comprised 1483 (49.4% female) adolescents representing around 80 different countries of origin, residing in Zurich, Switzerland. We found that young people who reported a better relationship with their teacher at age 10, engaged in fewer delinquent acts at ages 13, 15, and 17. These findings suggest that when young people perceive a better relationship with their teachers this serves as a protective factor against their engagement in delinquency up to 7 years later.

description: Structured growth of high quality graphene is necessary for technological development of carbon based electronics. Specifically, control of the bunching and placement of surface steps under epitaxial graphene on SiC is an important consideration for graphene device production. We demonstrate lithographically patterned evaporated amorphous carbon corrals as a method to pin SiC surface steps. Evaporated amorphous carbon is an ideal step-flow barrier on SiC due to its chemical compatibility with graphene growth and its structural stability at high temperatures, as well as its patternability. The amorphous carbon is deposited in vacuum on SiC prior to graphene growth. In the graphene furnace at temperatures above 1200$^\circ$C, mobile SiC steps accumulate at these amorphous carbon barriers, forming an aligned step free region for graphene growth at temperatures above 1330$^\circ$C. AFM imaging and Raman spectroscopy support the formation of quality step-free graphene sheets grown on SiC with the step morphology aligned to the carbon grid.

In the present paper, we prove congruence identities of RMZVs of depth $n$ involving a pair of index sets; the congruence relation is given by the vector space spanned by MZVs of depth $n-1$ and products of MZVs. We also obtain a proof of the parity result, and a congruence sum formula for MZVs.

description: We investigate the role of the substrate for the strength of the electon phonon coupling in Li-decorated graphene. We find that the interaction with a $h$-BN substrate leads to a significant enhancement from $λ_0=0.62$ to $λ_1=0.67$, which corresponds to a $25\%$ increase of the transition temperature from $T_{c0}=10.33$ K to $T_{c1}=12.98$ K. The superconducting gaps amount to 1.56 meV (suspended) and 1.98 meV (supported). These findings open up a new route to enhanced superconducting transition temperatures in graphene-based materials by substrate engineering.

Setting up a Governance Framework for Secondary Use of Routine Health Data in Nursing Homes: Development Study Using Qualitative Interviews
Creators: name: Wieland-Jorna, Yvonne
Publisher: name: Zenodo
Year: 2023

description: Background: In the nursing home sector, reusing routinely recorded EHR data for knowledge development and quality improvement is in its infancy. A data governance framework (who may access the data, under what conditions, and for what purposes) can help obtaining trust in appropriate and responsible data reuse. Little guidance is available on development and implementation of data governance frameworks in practice.
Objective: To describe the development process of a governance framework for the  "Registry Learning from Data in Nursing Homes" – a Dutch national registry for EHR data on care delivered by nursing home physicians.
Methods: Interviews were conducted with stakeholders representing practices, policies, and research in the nursing home sector. Main aim was to explore perspectives regarding the Registry's aim, data access criteria, and governing bodies' tasks and composition. Interview topics and analyses were guided by 8 health data governance principles. Interview results, together with legal advice and consensus discussions were used to shape the rules, regulations, and governing bodies of the framework.
Results: Stakeholders saw the involvement of nursing home residents, nursing home physicians, boards of directors, and scientists as a prerequisite for a trustworthy data governance framework. For the Registry, their involvement can be achieved through a consent procedure, transparency, and a position in a governing body. In addition, a data request approval procedure indicates that data reuse by third parties aligns with the aims of the Registry, benefits the nursing home sector, and protects the privacy of data subjects.
Conclusions: Stakeholders' views, expertise, and knowledge of other frameworks and relevant legislation serve to inform the application of governance principles to the contexts of both the nursing home sector and the Netherlands. Engagement of the full range of stakeholders in an early stage of governance framework development is important to generate trust in appropriate and responsible data reuse.

Anstelle eines trüben Materialismus geistloser Atome und Billardkugeln, der üblicherweise heraufbeschworen wird, um den Spaß in der Philosophie zu verderben, werde ich einen selt-samen Realismus verteidigen. Dieses Modell beinhaltet eine Welt, vollgepackt mit gespenstigen, realen Objekten, die sich gegenseitig aus unerforschlicher Tiefe Signale senden und unfähig sind sich einander ganz zu berühren. Hier besteht eine offenkundige Bezie-hung zur Tradition, die als Okkasionalismus bekannt ist und die als Erste nahelegte, dass eine direkte Wechselwirkung zwischen Entitäten unmöglich sei. Eine andere klare Verbindung besteht zur verwandten skeptischen Tradition, die Objekte als nebenein-anderliegend und ohne direkte Verbindung betrachtet, obwohl die betreffenden Objekte hier eher menschliche Wahrnehmungen, denn reale unabhängige Objekte sind. Dennoch wird dieser Artikel die Lösung des Problems durch eine einsame, magische Superentität, die verantwortlich für jede Relation ist (sei es Gott für Malebranche und seine irakischen Vorläufer oder der menschliche Geist für Skep-tiker, Empiristen und Idealisten), zugunsten einer stellvertretenden Verursachung verwerfen, welche lokal über jeden Teil des Kosmos verteilt ist. Obwohl ihre Seltsamkeit eher zu Verwunderung als zu Widerstand führen mag, ist stellvertretende Verursachung nicht irgendein autistischer Mondstrahl, der durch das Fenster eines Asyls eindringt. Stattdessen ist sie die Startrampe für eine rigoros post-heideggerianische Philosophie einerseits, wie die angemes-sene Rückkehr zum ehrwürdigen Problem der Kommunikation zwischen Substanzen andererseits.

Im Gegensatz zu „Laienwörterbüchern“, die oftmals einen Schwerpunkt auf dialektale Ausdrücke einer bestimmten Region legen, deckt „Wortgut“ das gesamte Spektrum von Standard bis Non-Standard ab und ermöglicht es den Teilnehmenden ausgehend von ihrem lexikographischen Vorwissen in unterschiedlichen Schwierigkeitsstufen sprachliche Ausdrücke zu erfassen. Obwohl „Wortgut“ damit die Brücke zu professionell erstellten Wörterbüchern schlägt, erfolgt jedoch keine Qualitätskontrolle der Einträge der Benutzer*innen. Dies erschwert zwar die Interoperabilität und Kompatibilität mit anderen Wörterbüchern, ermöglicht allerdings die Untersuchung der Einträge aus perzeptions- und variationslinguistischer Forschungsperspektive. Durch die freie Themenwahl der Teilnehmenden deckt „Wortgut“ somit nicht nur Standardsprache, Jugendsprache, Fachsprache und Dialekt ab, sondern auch Sprache in der multimedialen Kommunikation.

description: The channel size distribution in hard sphere systems, based on the local neighbor correlation of four particle positions, is investigated for all volume fractions up to jamming. For each particle, all three particle combinations of neighbors define channels, which are relevant for the concept of caging. The analysis of the channel size distribution is shown to be very useful in distinguishing between gaseous, liquid, partially and fully crystallized, and glassy (random) jammed states. A common microstructural feature of four coplanar particles is observed in crystalline and glassy jammed states, suggesting the presence of "hidden" two-dimensional order in three-dimensional random close packings.

description: The Temporal and Spectral variations of black hole candidates during outbursts have been reported in several publications. It is well known that during an outburst, the source becomes soft in the first few days, and then returns to the hard state after a few weeks or months. In the present paper, we show the variation of Comptonization Efficiency (CE), obtained from the ratio of the black body photon number to the power-law photon number, as a function of time in several outbursts. Since the power-law photons are generated through inverse-Comptonization of the intercepted soft photons, the CE is a measure of the geometry of the Compton cloud. Our investigation indicated that all the outbursts starts with a large CE and becomes very small after a few days, when the Compton cloud becomes very small to intercept any significant number of soft photons. CE returns back to a larger value at the end of the outburst.

Ediacaran and Anthropocene: Poetry as a Reader of Deep Time
Creators: name: McKay, Don
Publisher: name: punctum books
Year: 2012

description: Two new developments in the taxonomy of temporality provide the focus for this discussion. One is the official recognition of a new, and very old, geologic period, the Ediacaran, now understood to occupy the stretch of deep time between 575 and 542 million years ago, directly preceding the Cambrian, with its remarkable radiation of life forms. This recognition is precipitated by the discovery, dating, and analysis of thirty or so species representing an entirely new biota in the fossil record, the earliest animals on the planet. The other wrinkle in our idea of time involves the proposal to name, or re-name, the current epoch after the species that has been most responsible for its character and style, as well as the content of most of its narratives. “The Anthropocene,” if accepted, would acknowledge ourselves as the superstars we have been for some time.
Sobre a viagem de Enrico Fermi ao Brasil em 1934

description: Enrico Fermi was one of the greater physicists of the XX century. In 1934, he gave several lectures in Brazil. Invited by Theodoro Ramos to work in São Paulo, he preferred to stay in Rome and went to the USA in 1938. However, Fermi recommended Gleb Wataghin to come in his place. Wataghin made history in Brazil, becoming one of the first Professors of the future São Paulo University. Besides his relevance to the History of Science, Fermi eventually leaved an indelible mark on the creation and institutionalization of national scientific research due to the indication of Wataghin. Despite this fact, very little is known about Fermi's trip to Brazil. This work tries to reconstruct the fullest possible steps of the famous Italian physicist in our lands.

description: Traffic flow of athletes in classic-style cross-country ski marathons, with the Swedish Vasaloppet as prominent example, represents a non-vehicular system of driven particles with many properties of vehicular traffic flow such as unidirectional movement, the existence of lanes, and, moreover, severe traffic jams. We propose a microscopic acceleration and track-changing model taking into account different fitness levels, gradients, and interactions between the athletes in all traffic situations. The model is calibrated on microscopic data of the $\textit{Vasaloppet 2012}$ Using the multi-model open-source simulator MovSim.org, we simulate all 15 000 participants of the Vasaloppet during the first ten kilometers.

Ultra-Diamond / Super-Value

description: The diamond, as we know it, is a unique example of marketing and monetization of a geological resource.  Through  careful  supply-control,  advertising,  and  cultural  massaging,  the  industry  has managed to mythologize a geological material in cultures around the world. Throughout the  20th  century,  rituals,  expectation,  and  meaning  have  been  intentionally  crafted  around  the  diamond  through  tales  of  rarity  and  carat-value.  A  complete  mythology,  ranging  from  sparkling wedding rings to shady deals and overworked mines, surrounds each of these stones and furthers the mystery as well as desire. As  a  counterpoint  to  this  aesthetic  industry,  a  new  functional  aspect  is  emerging  as  dia-monds are grown in the lab with ever increasing control and huge promises for technological applications. The unique properties of diamond as a super-material open up potentially revo-lutionary  breakthroughs  in  fields  as  varied  as  quantum  computing,  electronics,  biosensors,  and clean energy.

description: When a test of attention, such as the d2 test, is repeated, performance improves. These practice benefits threaten the validity of a test because it is impossible to separate the contributions of ability and practice, respectively, to a particular result. A possible solution to this dilemma would be to determine the sources of practice effects, and to use this knowledge for constructing tests that are less prone to practice. The present study investigates the contribution of three components of a d2-like test of attention to practice benefits: targets, distractors, and stimulus configurations. In Experiment 1, we compared practice effects in a target-change condition, where targets changed between sessions, to a target-repetition condition. Similarly, in Experiment 2, we compared practice effects in a distractor-change condition to a distractor-repetition condition. Finally, in Experiment 3, we compared practice effects in a position-repetition condition, where stimulus configurations were repeated within and between tests, to a position-change condition. Results showed that repeating targets and repeating distractors contribute to practice effects, whereas repeating stimulus configurations does not. Hence, in order to reduce practice effects, one might construct tests in which target learning is prevented, for example, by using multiple targets.

Cosmological QCD phase transition in steady non-equilibrium dissipative Hořava-Lifshitz early universe

description: We study the phase transition from quark-gluon plasma to hadrons in the early universe in the context of non-equilibrium thermodynamics. According to the standard model of cosmology, a phase transition associated with chiral symmetry breaking after the electro-weak transition has occurred when the universe was about $1-10μs$ old. We focus attention on such a phase transition in the presence of a viscous relativistic cosmological background fluid in the framework of non-detailed balance Hořava-Lifshitz cosmology within an effective model of QCD. We consider a flat Friedmann-Robertson-Walker Universe filled with a non-causal and causal bulk viscous cosmological fluid respectively and investigate the effects of the running coupling constants of Hořava-Lifshitz gravity, $λ$, on the evolution of the physical quantities relevant to a description of the early universe, namely, the temperature $T$, scale factor $a$, deceleration parameter $q$ and dimensionless ratio of the bulk viscosity coefficient to entropy density $\fracξ{s}$. We assume that the bulk viscosity cosmological background fluid obeys the evolution equation of the steady truncated (Eckart) and full version of the Israel-Stewart fluid, respectively.

description: In recent years, adipose-derived stem cells (ADSCs) and derived exosomes (ADSC-Ex) have been investigated for their therapeutic potential in various diseases due to their satisfactory differentiation and regeneration ability. We aimed to explore the potential treatment of ADSCs and ADSC-Ex for testicular injury caused by cisplatin. ADSCs and ADSC-Ex s were identified and extracted to treat the rat model with testicular injury caused by cisplatin. Then the immunohistochemistry and ELISA assay were used to detect the potential treatment of ADSCs and ADSC-Ex. We found that ADSCs and ADSC-Ex significantly improved the testicular tissue damage, increased the number of germ cells, and improved the arrangement of the seminiferous tubules. The levels of malondialdehyde and testosterone were also improved. We speculated that ADSCs and ADSC-Ex may alleviate the testicular injury caused by cisplatin.
