Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Single crystals of a new ternary aluminide ErV$_2$Al$_{20}$ were grown using a self-flux method. The crystal structure was determined by powder X-ray diffraction measurements and Rietveld refinement, and physical properties were studied by means of electrical resistivity, magnetic susceptibility and specific heat measurements. These measurements reveal that ErV$_2$Al$_{20}$ is a Curie-Weiss paramagnet down to 1.95 K with an effective magnetic moment $μ_{eff}$ = 9.27(1) $μ_B$ and Curie-Weiss temperature $Θ_{CW}$ = -0.55(4) K. The heat capacity measurements show a broad anomaly at low temperatures that is attributed to the presence of a low-energy Einstein mode with characteristic temperature $Θ_E$ = 44 K, approximately twice as high as in the isostructural 'Einstein solid' VAl$_{10.1}$.

description: Through a review of the literature covering the use of intuition for decision making, this article isolates the important intuition determining variables and relates them to recent quantitative intuition research. As most farm decisions are made through intuition farmers, consultants, researchers and students of farm management will find the review valuable when thinking about managerial ability. The literature reviewed is taken from both urban and rural business studies as urban based studies dominate. The search covered all journals and articles in recent decades. The summary, and the quoted quantitative research, consider the variables which can be targeted in improving intuitive skill and provides a basis for thinking about intuition and its improvement within the farming world. It is concluded the most important skill to concentrate on is improving a farmer’s self-criticism through using a decision diary in conjunction with reflection and consultation leading to improved decision understanding. But many other variables are also important and contribute.
The effects of high frequency strengthening on indicators of central and peripheral pain sensitization, pain, function, and behavioral outcomes in female runners with chronic patellofemoral pain

description: Patellofemoral pain (PFP) is a common overuse injury sustained by runners, affecting females at a higher rate than males. The etiology of PFP is thought to be multifactorial, with evidence in support of biomechanical and overuse/overtraining models based on recent clinical practice guidelines. Traditional management of PFP focuses on addressing biomechanical impairments and patient education for appropriate load management and gradual progression of activity, however many patients with PFP continue to report chronic pain, limited function, and disability. Current literature has demonstrated that some patients with chronic musculoskeletal pain conditions, including PFP, exhibit signs of central sensitization. Nervous system sensitization can be identified through quantitative sensory testing (QST), of which includes pressure pain threshold testing, conditioned pain modulation, and temporal summation measures. The purpose of this dissertation is to understand the relationship between QST and psychological variables in a population of female runners with chronic PFP, and to investigate the effectiveness of a high frequency strengthening program to change pain sensitization, functional outcomes, and behavioral characteristics in this group. The results support the presence of nervous system sensitization in female runners with chronic PFP when compared to healthy controls, through a reduction in pressure pain threshold local to the knee (primary hyperalgesia) and to remote sites (secondary hyperalgesia). Following the implementation of an 8-week high frequency strength training program, there were clinically meaningful and statistically significant improvements in self-reported pain and function in female runners with chronic PFP symptoms at 8 and 12 weeks. A significant improvement in pain sensitivity measures, via pressure pain threshold at local and remote sites and heat pain threshold, represents a favorable change in signs of peripheral and central sensitization. A statistically significant improvement in fear of movement and anxiety at 12 weeks post intervention, with a trend towards improved catastrophizing was also found. The results from this dissertation provides clinicians with evidence for the effectiveness of high frequency strengthening to improve pain, function, pain sensitivity, and behavioral characteristics for individuals with chronic PFP.

description: Biomarkers have become increasingly significant in veterinary practice, providing valuable insights into the diagnosis, prognosis, and monitoring of diseases in animals. These measurable indicators, derived from sources such as blood, urine, and tissues, offer a non-invasive and precise means to detect underlying health conditions, often before clinical signs are apparent. The application of biomarkers in veterinary medicine has advanced alongside developments in genomic, proteomic, and metabolomic technologies, enabling the identification of species-specific biomarkers that enhance diagnostic accuracy. Moreover, biomarkers play a pivotal role in monitoring treatment responses and facilitating personalized medicine, ensuring that therapeutic interventions are tailored to the individual needs of animals. Despite challenges related to standardization, technical limitations, and biological variability across species, the integration of biomarkers in routine veterinary practice has the potential to improve patient outcomes, optimize treatment plans, and advance veterinary healthcare. This paper explores the significance of biomarkers in veterinary medicine, highlighting their applications, challenges, and future prospects in the field.

description: The UK Parliament performs an important role in shaping policies and legislation, including those related to agriculture. Parliamentarians (MPs and Peers) and the staff supporting them often want to use evidence to inform the passage of legislation and the scrutiny of government policy since it decreases the chances of making a bad decision. This viewpoint explores how communities of science and practice working in the agricultural sphere can engage with Parliament to ensure that evidence informs decision-making. It makes five recommendations: (1) know how to engage with parliamentary processes, (2) communicate relevant evidence in a clear and concise fashion, (3) ensure that evidence is credible, (4) work with trusted knowledge brokers, and (5) persevere over a long timescale.
Unveiling the capabilities of bipolar conical channels in neuromorphic iontronics

description: Conical channels filled with an aqueous electrolyte have been proposed as promising candidates for iontronic neuromorphic circuits. This is facilitated by a novel analytical model for the internal channel dynamics [Kamsma et al., arXiv:2301.06158, 2023], the relative ease of fabrication of conical channels, and the wide range of achievable memory retention times by varying the channel lengths. In this work, we demonstrate that the analytical model for conical channels can be generalized to channels with an inhomogeneous surface charge distribution, which we predict to exhibit significantly stronger current rectification and more pronounced memristive properties in the case of bipolar channels, i.e. channels where the tip and base carry a surface charge of opposite sign. Additionally, we show that the use of bipolar conical channels in a previously proposed iontronic circuit features hallmarks of neuronal communication, such as all-or-none action potentials and spike train generation. Bipolar channels allow, however, for circuit parameters in the range of their biological analogues, and exhibit membrane potentials that match well with biological mammalian action potentials, further supporting its potential for bio-compatibility.

description: Recent observations have shown that a growing number of the most massive Galactic globular clusters contain multiple populations of stars with different [Fe/H] and neutron-capture element abundances. NGC 6273 has only recently been recognized as a member of this "iron-complex" cluster class, and we provide here a chemical and kinematic analysis of > 300 red giant branch (RGB) and asymptotic giant branch (AGB) member stars using high resolution spectra obtained with the Magellan-M2FS and VLT-FLAMES instruments. Multiple lines of evidence indicate that NGC 6273 possesses an intrinsic metallicity spread that ranges from about [Fe/H] = -2 to -1 dex, and may include at least three populations with different [Fe/H] values. The three populations identified here contain separate first (Na/Al-poor) and second (Na/Al-rich) generation stars, but a Mg-Al anti-correlation may only be present in stars with [Fe/H] > -1.65. The strong correlation between [La/Eu] and [Fe/H] suggests that the s-process must have dominated the heavy element enrichment at higher metallicities. A small group of stars with low [alpha/Fe] is identified and may have been accreted from a former surrounding field star population. The cluster's large abundance variations are coupled with a complex, extended, and multimodal blue horizontal branch (HB). The HB morphology and chemical abundances suggest that NGC 6273 may have an origin that is similar to omega Cen and M 54.

description: This thesis examines the role of the state in the pharmaceuticalization of Tic Disorders (TD) and ADHD in China. Empirically, it investigates the factors that led to institutional disparities in the professional associations for TD and ADHD, two medical conditions that often coexist, during the Xi Jinping era. It asks why a national-scale, hierarchical professional association has formed around TD, a condition less diagnosed and recognized, while ADHD remains a decentralized organizational structure to date. Adopting a mixed-methods approach, this research draws on data from interviews with fifteen pediatricians, ethnographic observations at six medical conferences, and extensive digital archives, including 40 hours of conference recordings, publications in 20 medical journals and newspapers, China’s healthcare and pharmaceutical policies, and sales statistics for TD and ADHD drugs in China’s market. It argues that the contested biomedical knowledge of TD created a space for a robust network of expertise to coalesce around tics and its biopharmaceutical medication, LittlePatch. By contrast, the well-established biomedical knowledge of ADHD precluded the space to assemble a similarly centralized network of expertise around ADHD and its medications. Within these expertise networks, state actors played a central role in shaping the structure of professional associations for managing these medical conditions. This research enriches our understanding of the state’s multifaceted roles in driving medicalization processes.

Adhesive contact mechanics of viscoelastic materials

description: In this study, we propose a theory of rough adhesive contact of viscoelastic materials in steady-state sliding. By exploiting a boundary formulation based on Green function approach, the unknown contact domain is calculated by enforcing the local energy balance at the contact edge, thus considering also the non-conservative work of internal stresses which is directly related to the odd part of the Green function. Theoretical predictions indicate that viscoelasticity may enhance the adhesive performance depending on the sliding velocity, thus leading to larger contact area and pull-off force compared to the equivalent adhesive elastic case The interplay between viscoelasticity and adhesion also affects the overall friction. Indeed, at low velocity, friction is strongly enhanced compared to the adhesiveless viscoelastic case, mainly due to the small-scale viscoelastic hysteresis induced by the adhesive neck close to the contact edge At higher velocity, the effect of viscoelastic hysteresis occurring at larger scales (bulk material) leads to even higher friction. Under these conditions, in the presence of adhesion, the small-scale and large-scale viscoelastic contributions to friction cannot be separated. Finally, in contrast with usual predictions for crack propagation/healing in infinite systems, we found a non-monotonic trend of the energy release rates at the trailing and leading contact edges, which is consistent with the finiteness of the contact length. All the presented results are strongly supported by existing experimental evidences.

description: Transmission spectroscopy facilitates the detection of molecules and/or clouds in the atmospheres of exoplanets. Such studies rely heavily on space-based or large ground-based observatories, as one needs to perform time- resolved, high signal-to-noise spectroscopy. The FORS2 instrument at ESO's Very Large Telescope is the obvious choice for performing such studies, and was indeed pioneering the field in 2010. After that, however, it was shown to suffer from systematic errors caused by the Longitudinal Atmospheric Dispersion Corrector (LADC). This was successfully addressed, leading to a renewed interest for this instrument as shown by the number of proposals submitted to perform transmission spectroscopy of exoplanets. We present here the context, the problem and how we solved it, as well as the recent results obtained. We finish by providing tips for an optimum strategy to do transmission spectroscopy with FORS2, in the hope that FORS2 may become the instrument of choice for ground-based transmission spectroscopy of exoplanets.

More generally, for any exact $\infty$-category $E$, we construct an exact $\infty$-category $S^{-1}E$ of equivariant sheaves on the Cantor space with respect to an action of a dense subgroup of the circle. We show that this $\infty$-category is precisely the result of categorifying division by the primes in $S$. In particular, $K_n(S^{-1}E)\cong S^{-1}K_n(E)$.

description: Design and development of low-cost, low-power sensors and sensing systems are active research areas in building the effortless smart city. This dissertation proposes novel compact systems applicable to a smart city scenario. Firstly, a pedestrian counting and environmental monitoring sensor node has been developed to count the number of pedestrians and their travel direction and provide ambient parameters (temperature, humidity, pressure, CO2, and TVOC). The novelty of this work is improving the accuracy by innovative system design and developing intelligent algorithms even though using off the shelf devices. The importance of developing selective sensors to monitor air quality has been realised while working with commercial sensors. Hence, a graphene oxide (GO)-coated planar interdigital sensor has been developed to induce selectivity towards CO2. The sensor detects a wide range of CO2 concentrations from 400 ~ 4000 ppm. The novelty of this work lies in compensating the temperature and humidity effect to make it applicable in actual environmental conditions and measure CO2 concentrations with more than 95% accuracy. Moreover, Reduced Graphene Oxide and Aluminum-doped zinc oxide (rGO/Al-ZnO) and Reduced Graphene Oxide and Tin oxide (rGO/SnO2) nanocomposites have been synthesised for selective detection of Acetone (C3H6O) and Ethylene (C2H2), respectively. The sensors detect and differentiate acetone and ethylene concentrations from 10 ppb to 300 ppb. The significant contributions of this research are improving the response and recovery time, detection limit, and developing an intelligent sensing system to monitor air quality using these sensors. Water is another essential aspect of a smart city and smart agriculture. Hence, finally, a flexible Multi-Walled Carbon Nanotubes (MWCNTs)/Polydimethylsiloxane (PDMS) based sensor has been fabricated for nitrate (0.1~25 ppm), phosphate (0.1~25 ppm), calcium (1~200 ppm), magnesium (1~200 ppm), and pH (1.3~12.4) detection in water. A novelty of this work is utilising a machine-learning algorithm to classify the data and predict the amount of water quality parameters using only one sensor and without utilising selective coating. Additionally, a smart autonomous and portable system has been designed for real-time water quality monitoring from any remote location. These systems and sensors provide an opportunity for decision-makers to test assumptions and strategies and provide a healthy and safe environment for all of us.

description: This work represents a first systematic attempt to create a common ground for semi-classical and time-frequency analysis. These two different areas combined together provide interesting outcomes in terms of Schrödinger type equations. Indeed, continuity results of both Schrödinger propagators and their asymptotic solutions are obtained on $\hbar$-dependent Banach spaces, the semi-classical version of the well-known modulation spaces. Moreover, their operator norm is controlled by a constant independent of the Planck's constant $\hbar$. The main tool in our investigation is the joint application of standard approximation techniques from semi-classical analysis and a generalized version of Gabor frames, dependent of the parameter $\hbar$. Continuity properties of more general Fourier integral operators (FIOs) and their sparsity are also investigated.

description: In this paper, I briefly elaborate on the differences between two notions of third space, one rooted in postcolonial theory, the other in Marxist geography. Marxist geography is concerned with the production of antagonistic spatialities. I use this idea to analyze various notions of space of and in the Iranian Iron Age polity of the Medes. The main issue is the interpretation of “squatting” habitations at the two sites of Tepe Nush-i Jan and Godin Tepe. I argue that the flimsy walls set into the massive architecture of earlier levels are a sign of tensions over conflictual spatialities.

Χρησιμοποιώντας την ανάλυση παλινδρόμησης με σταθερές επιδράσεις, η μελέτη διαπιστώνει ότι οι εταιρείες με υψηλότερες επιδόσεις ESG επιτυγχάνουν ανώτερες χρηματοοικονομικές αποδόσεις, όπως υποδεικνύεται από την αυξημένη κεφαλαιοποίηση της αγοράς και τις καλύτερες αποδόσεις ιδίων κεφαλαίων (RoE). Τα αποτελέσματα υπογραμμίζουν την κρίσιμη σημασία της βιωσιμότητας και των υπεύθυνων πρακτικών διακυβέρνησης για την ενίσχυση της οικονομικής σταθερότητας και της εμπιστοσύνης των επενδυτών. Οι προτάσεις για μελλοντικές έρευνες περιλαμβάνουν την ανάλυση των επιμέρους στοιχείων των ESG, όπως οι περιβαλλοντικές, κοινωνικές και διακυβερνητικές πρακτικές, για να προσδιοριστεί η ακριβής επίδρασή τους στην κεφαλαιοποίηση της αγοράς.

description: Ballistic electrons in solids can have mean free paths far larger than the smallest features patterned by lithography. This has allowed development and study of solid-state electron-optical devices such as beam splitters and quantum point contacts, which have informed our understanding of electron flow and interactions. Recently, high-mobility graphene has emerged as an ideal two-dimensional semimetal that hosts unique chiral electron-optical effects due to its honeycomb crystalline lattice. However, this chiral transport prevents simple use of electrostatic gates to define electron-optical devices in graphene. Here, we present a method of creating highly-collimated electron beams in graphene based on collinear pairs of slits, with absorptive sidewalls between the slits. By this method, we achieve beams with angular width 18 degrees or narrower, and transmission matching semiclassical predictions.

description: In order to make precision measurements of neutrino oscillations using few-GeV neutrino beams a detailed understanding of nuclear effects in neutrino scattering is essential. Recent studies have revealed that single-transverse kinematic imbalance (STKI), defined in the plane transverse to an incoming neutrino beam, can act as a unique probe of these nuclear effects. This work first illustrates that an exclusive measurement of STKI at the off-axis near detector of the T2K experiment (ND280) is expected distinguish the presence of interactions with two nucleons producing two holes (2p-2h) from alterations of the predominant underlying cross-section parameter ($M_A$ - the nucleon axial mass). Such a measurement is then demonstrated with fake data, showing substantial nuclear model separation potential.

Measurements of inclusive J/$ψ$ production at midrapidity and forward rapidity in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV

description: The measurements of the inclusive J/$ψ$ yield at midrapidity ($\left | y \right | < 0.9$) and forward rapidity (2.5 $< y <$ 4) in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with the ALICE detector at the LHC are reported. The inclusive J/$ψ$ production yields and nuclear modification factors, $R_{\rm AA}$, are measured as a function of the collision centrality, J/$ψ$ transverse momentum ($p_{\rm T}$), and rapidity. The J/$ψ$ average transverse momentum and squared transverse momentum ($\langle p_{\mathrm{T}}\rangle$ and $\langle p_{\mathrm{T}}^{\mathrm{2}}\rangle$) are evaluated as a function of the centrality at midrapidity. Compared to the previous ALICE publications, here the entire Pb$-$Pb collisions dataset collected during the LHC Run 2 is used, which improves the precision of the measurements and extends the $p_{\rm T}$ coverage. The $p_{\rm T}$-integrated $R_{\rm AA}$ shows a hint of an increasing trend towards unity from semicentral to central collisions at midrapidity, while it is flat at forward rapidity. The $p_{\rm T}$-differential $R_{\rm AA}$ shows a strong suppression at high $p_{\rm T}$ with less suppression at low $p_{\rm T}$ where it reaches a larger value at midrapidity compared to forward rapidity. The ratio of the $p_{\rm T}$-integrated yields of J/$ψ$ to those of D$^{0}$ mesons is reported for the first time for the central and semicentral event classes at midrapidity. Model calculations implementing charmonium production via the coalescence of charm quarks and antiquarks during the fireball evolution (transport models) or in a statistical approach with thermal weights are in good agreement with the data at low $p_{\rm T}$. At higher $p_{\rm T}$, the data are well described by transport models and a model based on energy loss in the strongly-interacting medium produced in nuclear collisions at the LHC.

description: Premelting of ice within pores in earth materials is shown to depend on the presence of vapor layers. For thick vapor layers between ice and pore surfaces, a nanosized water sheet can be formed due to repulsive Lifshitz forces. In the absence of vapor layers, ice is inhibited from melting near pore surfaces. In between these limits, we find an enhancement of the water film thickness in silica and alumina pores. In the presence of metallic surface patches in the pore, the Lifshitz forces can dramatically widen the water film thickness, with potential complete melting of the ice surface.

description: This session was created to create awareness on the variety and case-specific use of Data infrastructure. Attendees in this session are divided in two groups, within these groups they receive different use cases of research with a certain dataset. To discover this topic, the attendees will go over to a snake/ladder game in which players can be going forward by making the right data storage choices for the right case (in terms of what would be the most applicable). If they are wrong they can go steps forward, if not they go back. The attendees get advice cards on possible data storage that informs them about why this one would better not be used for some cases.

description: El ecosistema cerrado de pagos, que en Colombia no hace parte del Sistema de Pagos regular, en especial del de Bajo Valor, es una infraestructura transaccional alternativa a la que no le es aplicable la normatividad local relacionada con los Sistemas de Pago de Bajo Valor. Este ecosistema, el cual ha sido denominado sistema cerrado transaccional, merece ser estudiado a mayor profundidad, ya que podría incentivar la inclusión financiera de aquella población de bajos ingresos y aumentar el acceso al crédito. Lo anterior, no obsta para que, de la mano de las olas disruptivas de innovación, se trabaje en la estructuración de mecanismos sustitutos que no limiten el flujo transaccional al Sistema de Pagos de Bajo Valor.
description: The closed loop payment ecosystem, that is not included within de regular Payment System in Colombia, specifically Low Value, is an alternative transactional infrastructure that is not covered by local Low Value Payment Systems regulation. This ecosystem, that has been called closed loop payment ecosystem, deserves to be deeply studied, because it could increase the financial inclusion of the population with the lowest incomes and develop the credit access. In this regard, the disrupting innovation waves may work upon new mechanisms that will not be limited to Low Value Payment Systems.

description: In modified two-neighbour bootstrap percolation in two dimensions each site of $\mathbb Z^2$ is initially independently infected with probability $p$ and on each discrete time step one additionally infects sites with at least two non-opposite infected neighbours. In this note we establish that for this model the second term in the asymptotics of the infection time $τ$ unexpectedly scales differently from the classical two-neighbour model, in which arbitrary two infected neighbours are required. More precisely, we show that for modified bootstrap percolation with high probability as $p\to0$ it holds that \[τ\le \exp\left(\frac{π^2}{6p}-\frac{c\log(1/p)}{\sqrt p}\right)\] for some positive constant $c$, while the classical model is known to lack the logarithmic factor.
