description: Antifogging films are used in an increasing number of applications in greenhouse cultivation because fog formation affects transmission. Here, we summarize a way to improve the antifogging duration of linear low-density polyethylene (LLDPE) films by controlling the migration of the antifog agent. We prepared SiO2-grafted glycerin monostearate (SiO2-g-GMS) by covalently grafting surface modified SiO2 nanoparticles and glycerin acrylic acid monostearate (GMS-AA). Then, SiO2-g-GMS was added in LLDPE, and antifogging films were prepared for study of their properties. The reaction with modified SiO2 and GMS-AA was demonstrated by Fourier transform infrared spectroscopy, thermogravimetric analysis and grafting degree (GD). The GD of SiO2-g-GMS was approximately 54.95%. Accelerating dripping experiments and contact angle measurements illustrated that GMS-AA-grafted modified SiO2 exhibited delayed migration of the antifog agent, prolonging the antifogging duration by approximately 3 days. We determined that 3 wt% SiO2-g-GMS was a suitable proportion, considering economy and the desired properties. The SEM images indicate that dispersion of SiO2-g-GMS in the film was extensive, and the particle size was 160 ± 40 nm. In addition, the study also showed how modified SiO2 grafted with GMS-AA does not affect the processes and usability of antifogging films.

description: Objective assessment of lameness is preferred to subjective assessment. There are few modalities that allow for both objective and non-contact assessment of lameness. The purpose of this trial was to evaluate two novel diagnostic tools, accelerometry and thermography, for lameness detection. We hypothesized that tri-axial accelerometry and thermography would allow for objective and non-contact assessment of lameness in calves.

description: No abstracts are to be cited without prior reference to the author.There has been an increased use of groundfish surveys as platforms for the sampling of macro-epibenthic fauna over wide geographical areas in recent years. Indeed, internationally coordinated studies have provided spatially comprehensive data for the North Sea. In contrast, the invertebrate fauna off the western coasts of the UK are more poorly known. Macro-epifaunal samples collected by 4m-beam trawl were used to determine the structure and diversity of demersal assemblages occurring along the western seaboard of the British Isles. Samples were collected during 2003 from the Celtic Sea/Bristol Channel (ICES division VIIf-g), Irish Sea (VII a) and the western English Channel (VIIe). Cluster analysis was used to determine the similarity of assemblages in the area, and the distribution of these assemblages was examined in relation to depth, substrate, latitude, water temperature, salinity and tidal stress. Stations in the Irish Sea were characterised by species typical of inshore grounds, including Pagurus bernhardus, Asterias rubens, Ophiura ophiura and Liocarcinus holsatus, with stations on the coarser grounds of the central Irish Sea and English Channel were typified by Pagurus prideaux. The relationships between epibenthic assemblages and the physical environment are discussed.

description: We study some natural generalizations of the spectral spaces in the contexts of commutative rings and distributive lattices. We obtain a topological characterization for the spectra of commutative (not necessarily unitary) rings and we find spectral versions for the up-spectral and down-spectral spaces. We show that the duality between distributive lattices and Balbes-Dwinger spaces is the co-equivalence associated to a pair of contravariant right adjoint functors between suitable categories.

description: We study the formation of dipolar excitons and their superfluidity in a black phosphorene double layer. The analytical expressions for the single dipolar exciton energy spectrum and wave function are obtained. It is predicted that a weakly interacting gas of dipolar excitons in a double layer of black phosphorus exhibits superfluidity due to the dipole-dipole repulsion between the dipolar excitons. In calculations are employed the Keldysh and Coulomb potentials for the interaction between the charge carriers to analyze the influence of the screening effects on the studied phenomena. It is shown that the critical velocity of superfluidity, the spectrum of collective excitations, concentrations of the superfluid and normal component, and mean field critical temperature for superfluidity are anisotropic and demonstrate the dependence on the direction of motion of dipolar excitons. The critical temperature for superfluidity increases if the exciton concentration and the interlayer separation increase. It is shown that the dipolar exciton binding energy and mean field critical temperature for superfluidity are sensitive to the electron and hole effective masses. The proposed experiment to observe a directional superfluidity of excitons is addressed.

description: Completely positive and completely bounded mutlipliers on rigid $C^{\ast}$-tensor categories were introduced by Popa and Vaes. Using these notions, we define and study the Fourier-Stieltjes algebra, the Fourier algebra and the algebra of completely bounded multipliers of a rigid $C^{\ast}$-tensor category. The rich structure that these algebras have in the setting of locally compact groups is still present in the setting of rigid $C^{\ast}$-tensor categories. We also prove that Leptin's characterization of amenability still holds in this setting, and we collect some natural observations on property (T).

description: The "double diffusivity" model was proposed in the late 1970s, and reworked in the early 1980s, as a continuum counterpart to existing discrete models of diffusion corresponding to high diffusivity paths, such as grain boundaries and dislocation lines. Technically, the model pans out as a system of coupled {\it Fick type} diffusion equations to represent "regular" and "high" diffusivity paths with "source terms" accounting for the mass exchange between the two paths. The model remit was extended by analogy to describe flow in porous media with double porosity, as well as to model heat conduction in media with two non-equilibrium local temperature baths e.g. ion and electron baths. Uncoupling of the two partial differential equations leads to a higher-ordered diffusion equation, solutions of which could be obtained in terms of classical diffusion equation solutions. Similar equations could also be derived within an "internal length" gradient (ILG) mechanics formulation applied to diffusion problems, {\it i.e.}, by introducing nonlocal effects, together with inertia and viscosity, in a mechanics based formulation of diffusion theory. This issue becomes particularly important in the case of diffusion in nanopolycrystals whose deterministic ILG based theoretical calculations predict a relaxation time that is only about one-tenth of the actual experimentally verified timescale. This article provides the "missing link" in this estimation by adding a vital element in the ILG structure, that of stochasticity, that takes into account all boundary layer fluctuations. Our stochastic-ILG diffusion calculation confirms rapprochement between theory and experiment, thereby benchmarking a new generation of gradient-based continuum models that conform closer to real life fluctuating environments.

description: This study aimed to establish an optimal model to predict the busulfan (BU) area under the curve at steady state (AUCss) by using machine learning (ML). Seventy-nine adult patients (age ≥18 years) who received BU intravenously and underwent therapeutic drug monitoring from 2013 to 2021 at Fujian Medical University Union Hospital were enrolled in this retrospective study. The whole dataset was divided into a training group and test group at the ratio of 8:2. BU AUCss were considered as the target variable. Nine different ML algorithms and one population pharmacokinetic (pop PK) model were developed and validated, and their predictive performance was compared. All ML models were superior to the pop PK model (R2 = 0.751, MSE = 0.722, 14 and RMSE = 0.830) in model fitting and had better predictive accuracy. The ML model of BU AUCss established through support vector regression (SVR) and gradient boosted regression trees (GBRT) had the best predictive ability (R2 = 0.953 and 0.953, MSE = 0.323 and 0.326, and RMSE = 0.423 and 0.425). All the ML models can potentially be used to estimate BU AUCss with the aim of facilitating rational use of BU on the individualized level, especially models built by SVR and GBRT algorithms.

description: Local Process Models (LPM) describe structured fragments of process behavior occurring in the context of less structured business processes. Traditional LPM discovery aims to generate a collection of process models that describe highly frequent behavior, but these models do not always provide useful answers for questions posed by process analysts aiming at business process improvement. We propose a framework for goal-driven LPM discovery, based on utility functions and constraints. We describe four scopes on which these utility functions and constrains can be defined, and show that utility functions and constraints on different scopes can be combined to form composite utility functions/constraints. Finally, we demonstrate the applicability of our approach by presenting several actionable business insights discovered with LPM discovery on two real life data sets.

description: High producing dairy cattle experience a state of negative energy balance in early lactation. Dairy cattle address this metabolic challenge by increasing the rate of fat and protein mobilization. Previous studies have emphasized the rate of fat mobilization and consequently the rate of protein mobilization has not been fully investigated. The primary objective of this study was therefore to characterize the change in muscle mass during early lactation using ultrasonography and plasma creatinine concentration (creatinine).

description: A series of combinations of alkyl halide with tertiary amine such as ethyl α-bromophenylacetate/tris[2-(dimethylamino)ethyl)]amine (αEBP/Me6TREN), ethyl 2-bromoisobutyrate/triethylamine (EBiB/TEA), and ethyl 2-chloropropionate/N,N,N′,N′,N′′-pentamethyldiethylenetriamine (ECP/PMDETA) have been developed as novel free radical initiators and used for the polymerizations of methyl acrylate (MA), methyl methacrylate (MMA) and styrene (St). The effects of the structure of alkyl halide and tertiary amine on the polymerization of MA were investigated. Gel permeation chromatograph (GPC) and proton nuclear magnetic resonance (1H NMR) have been utilized to analyze the end group of the obtained poly(methyl acrylate). Electron spin resonance (ESR) spectroscopy was employed to identify the structure of the radicals produced by αEBP/Me6TREN, and the results indicated that αEBP reacted with Me6TREN via a single electron transfer (SET) nucleophilic mechanism to produce corresponding ethyl α-phenylacetate radicals which subsequently initiated the polymerization of MA. As both alkyl halide and tertiary amine are commercially available at low cost, non-explosive, and ease of use and storage in comparison with conventional azo, peroxide or persulfate initiators, the combination of alkyl halide and tertiary amine as a free radical initiator is promising for large-scale practical applications.

description: A continuous time random walk (CTRW) model with waiting times following the Levy-stable distribution with exponential cut-off in equilibrium is a simple theoretical model giving rise to normal, yet non-Gaussian diffusion. The distribution of the particle displacements is explicitly time-dependent and does not scale. Since fluorescent correlation spectroscopy (FCS) is often used to investigate diffusion processes, we discuss the influence of this lack of scaling on the possible outcome of the FCS measurements and calculate the FCS autocorrelation curves for such equilibrated CTRWs. The results show that although the deviations from Gaussian behavior may be detected when analyzing the short and long-time asymptotic behavior of the corresponding curves, their bodies are still perfectly fitted by the fit forms used for normal diffusion. The diffusion coefficients obtaied from the fits may however differ considerably from the true tracer diffusion coefficients as describing the time dependence of the mean squared displacement

description: No abstracts are to be cited without prior reference to the author.In the Estuary and Gulf of St.Lawrence, krill is one of the key species of the food web. The stability and density of krill aggregations make the Gulf and Estuary important feeding grounds for large marine mammals (blue, fin, minke and humpback whales). These food aggregations result from the coupling of the circulation at local and regional scales with the diel vertical migration of krill. To estimate the effects of circulation changes on the krill distribution, a 3D regional circulation model was coupled with a vertical migration model. Eulerian tracers with different swimming behaviours were introduced in the model. The simulation results highlighted important spatial patterns but showed a high sensivity to the biological model. The zooplankton aggregations are mainly due to the interactions between the bathymetry and the tidal oscillations at the edge of the Laurentian channel and others secondary channels. Persistent retention areas are evidenced and are closely associated with regional circulation patterns and topography. They are located in the North-western Gulf (associated with the Anticosti gyre), around Anticosti Island and in the North-estearn Gulf. The distribution of the rich food concentrations are consistent with the rare synoptic information on large marine mammals distribution in the area.

description: Inducing sparseness while training neural networks has been shown to yield models with a lower memory footprint but similar effectiveness to dense models. However, sparseness is typically induced starting from a dense model, and thus this advantage does not hold during training. We propose techniques to enforce sparseness upfront in recurrent sequence models for NLP applications, to also benefit training. First, in language modeling, we show how to increase hidden state sizes in recurrent layers without increasing the number of parameters, leading to more expressive models. Second, for sequence labeling, we show that word embeddings with predefined sparseness lead to similar performance as dense embeddings, at a fraction of the number of trainable parameters.

description: No abstracts are to be cited without prior reference to the author.In this paper, the preliminary results of the application of an Individual Based Model (IBM) are presented. This model is used for the study of the spatio-temporal physical evolution of anchovy Engraulis encrasicolus in the Bay of Biscay, from its earliest life stage to juvenile ages under four months. The hydrodynamics used as input data for the IBM have been derived from the TRIMODENA model, developed using the Finite Element Method. The IBM predictions at the end of the study periods are compared with juvenile density field data. Differences obtained between the model results and field data show that the physical component of the modelling is not enough to explain the anchovy behaviour in the Bay of Biscay. These differences are attributed to biological processes that must be incorporated into the modelling in order to get a closer approximation to the real situation.
Relativistic quantum speed limit time in dephasing noise

description: The behavior of quantum speed limit time (QSLT) for a single free spin $-1/2$ particle described by Gaussian wavepackets in the framework of relativity under dephasing noise is investigated. The dephasing noise acts only on the spin degrees of freedom of the spin$-1/2$ particle. In particular, the effects of initial time parameter, rapidity, average momentum and the size of the wavepackets in the presence of the dephasing noise on the dynamics of evolution process are studied. In general, the effects of relativity monotonically decrease the QSLT in time. In the range of large values of average momentum, critical values of both the rapidity and the size of the wavepackets exist at which the QSLT has its minimum value. In the range of small values of the average momentum, the QSLT monotonically decreases with both rapidity and the size of the wavepackets. The decrease of QSLT in a particular range of rapidity and with other relative parameters may be of great interest in employing fast quantum communication and quantum computation.

We show that for any positive integer $k$, as the genus $g$ goes to infinity, the smallest $k$-th eigenvalue of Riemann surfaces in any thick part of moduli space of Riemann surfaces of genus $g$ is uniformly comparable to $\frac{1}{g^2}$ in $g$. In the proof of the upper bound, for any constant $ε>0$, we will construct a closed Riemann surface of genus $g$ in any $ε$-thick part of moduli space such that it admits a pants decomposition whose boundary curves all have length equal to $ε$, and the number of separating systole curves in this surface is uniformly comparable to $g$.

description: In recent years, the application of advanced analytics, especially artificial intelligence (AI), to digital H&E images, and other histological image types, has begun to radically change how histological images are used in the clinic. Alongside the recognition that the tumour microenvironment (TME) has a profound impact on tumour phenotype, the technical development of highly multiplexed immunofluorescence platforms has enhanced the biological complexity that can be captured in the TME with high precision. AI has an increasingly powerful role in the recognition and quantitation of image features and the association of such features with clinically important outcomes, as occurs in distinct stages in conventional machine learning. Deep-learning algorithms are able to elucidate TME patterns inherent in the input data with minimum levels of human intelligence and, hence, have the potential to achieve clinically relevant predictions and discovery of important TME features. Furthermore, the diverse repertoire of deep-learning algorithms able to interrogate TME patterns extends beyond convolutional neural networks to include attention-based models, graph neural networks, and multimodal models. To date, AI models have largely been evaluated retrospectively, outside the well-established rigour of prospective clinical trials, in part because traditional clinical trial methodology may not always be suitable for the assessment of AI technology. However, to enable digital pathology-based advanced analytics to meaningfully impact clinical care, specific measures of 'added benefit' to the current standard of care and validation in a prospective setting are important. This will need to be accompanied by adequate measures of explainability and interpretability. Despite such challenges, the combination of expanding datasets, increased computational power, and the possibility of integration of pre-clinical experimental insights into model development means there is exciting potential for the future progress of these AI applications. © 2023 The Authors.

Diffusive Mobile Molecular Communications Over Time-Variant Channels

description: This letter introduces a formalism for modeling time-variant channels for diffusive molecular communication systems. In particular, we consider a fluid environment where one transmitter nano-machine and one receiver nano-machine are subjected to Brownian motion in addition to the diffusive motion of the information molecules used for communication. Due to the stochastic movements of the transmitter and receiver nano-machines, the statistics of the channel impulse response change over time. We show that the time-variant behaviour of the channel can be accurately captured by appropriately modifying the diffusion coefficient of the information molecules. Furthermore, we derive an analytical expression for evaluation of the expected error probability of a simple detector for the considered system. The accuracy of the proposed analytical expression is verified via particle-based simulation of the Brownian motion.

This region is highly dynamic with water masses resulting from the mixing of Atlantic waters transported through the Straits of Dover and freshwater and nutrient inputs from the Scheldt, the Rhine and Meuse, the Seine, the Thames and other smaller rivers. However, the relative contribution of each river to the nutrient pool is not known. A 3D coupled physical-biological model (MIRO&CO-3D) has been used to assess the relative impact of a hypothetical reduction of the nutrients discharged from the Scheldt, Rhine, Meuse and Seine on the nutrient status of Belgian waters during the last decade. MIRO&CO-3D results from the coupling of the COHERENS 3D hydrodynamic model with the ecological model MIRO. The model has been set up for the region between 4°W (48.5°N) and 52.5°N (4.5°E). This model has been run to simulate the annual cycle of inorganic and organic nutrients, phytoplankton (diatoms & Phaeocystis), bacteria and zooplankton (microzooplankton & copepods) in the Southern Bight of the North Sea under realistic forcing (meteorology and river loads) for the period 1991-2000. The relative contribution of different rivers on the nutrient pool available for biological production is assessed by decreasing separately by 1% the nutrient loads from respectively the Scheldt, the Rhine (and Meuse) and the Seine (and smaller French rivers). This model scenario suggests that, on average for Belgian waters, a 1% reduction of nutrients loads from the river Seine would have a stronger impact on the nutrient (NO3 and PO4) status of Belgian waters than a 1% reduction from the Rhine or from the Scheldt.

description: Teat injuries are common in dairy cattle, around 2 to 3% are affected and compared to other frequently occurring diseases, these injuries often result in premature culling of affected cows. Teat injuries can be divided into 2 categories: external or internal injuries. These injuries often result in premature culling of affected cows. Surgery and treatment of these injuries has been described and discussed intensively. However the question whether complete rest (no milking) or temporary resting of the injured teat by temporary cessation of milking or continuous milking is not yet clearly answered, and may vary from case to case. This paper describes a new technique that allows a permanent milk flow alongside an undisturbed healing process of external and internal teat injuries. A special silicon catheter ("teatflow”) is introduced into the teat canal to allow continuous milk flow at a minimum risk level for udder infections.

description: We report the results from a recent 133 ks XMM-Newton observation of a highly super-Eddington narrow-line Type-1 QSO RX J0439.6-5311. This source has one of the steepest AGN hard X-ray slopes, in addition to a prominent and smooth soft X-ray excess. Strong variations are found throughout the 0.3 to 10 keV energy range on all time-scales covered by the observation, with the soft excess mainly showing low frequency variations below 0.1 mHz while the hard X-rays show stronger variability at higher frequencies. We perform a full set of spectral-timing analysis on the X-ray data, including a simultaneous modelling of the time-average spectra, frequency-dependent RMS and covariance spectra, lag-frequency and lag-energy spectra. Especially, we find a significant time-lag signal in the low frequency band, which indicates that the soft X-rays lead the hard by $\sim$4 ks, with a broad continuum-like profile in the lag spectrum. Our analysis strongly supports the model where the soft X-ray excess is dominated by a separate low temperature, optically thick Comptonisation component rather than relativistic reflection or a jet. This soft X-ray emitting region is several tens or hundreds of $R_{g}$ away from the hot corona emitting hard X-rays, and is probably associated with a geometrically thick (`puffed-up') inner disc region.

description: Aging facilitates the expansion of hematopoietic stem cells (HSCs) carrying clonal hematopoiesis-related somatic mutations and the development of myeloid malignancies, such as myeloproliferative neoplasms (MPNs). While cooperating mutations can cause transformation, it is unclear whether distinct bone marrow (BM) HSC-niches can influence the growth and therapy response of HSCs carrying the same oncogenic driver. Here we found different BM niches for HSCs in MPN subtypes. JAK-STAT signaling differentially regulates CDC42-dependent HSC polarity, niche interaction and mutant cell expansion. Asymmetric HSC distribution causes differential BM niche remodeling: sinusoidal dilation in polycythemia vera and endosteal niche expansion in essential thrombocythemia. MPN development accelerates in a prematurely aged BM microenvironment, suggesting that the specialized niche can modulate mutant cell expansion. Finally, dissimilar HSC-niche interactions underpin variable clinical response to JAK inhibitor. Therefore, HSC-niche interactions influence the expansion rate and therapy response of cells carrying the same clonal hematopoiesis oncogenic driver.
ANCORA SU WITTGENSTEIN. INTORNO A SCIENZA E FILOSOFIA

Subjects: Philosophy, Wittgenstein, Theory, Method, Naturalism, Platonism

description: The paper presents several reflections on the way Wittgenstein interpreted the relationship between philosophy and science. Particularly, this contribution highlights (a) how Wittgenstein’s criticism is not directed at science as such, but rather at the presumption that philosophy is and behaves as science (or as a science); and, consequently, (b) how Wittgenstein’s polemical target is what he sometimes defines as “metaphysics”. In fact, according to him, metaphysics arises precisely when (1) conceptual investigations are addressed with factuality, and when (2) in philosophy a certain theoretical attitude based on the search for the general and on reductionism is accepted. On this background the paper discusses (c) the connection that Wittgenstein’s philosophy holds, on the one hand with contemporary Naturalism and, on the other, with the most recent critiques of philosophy as conceptual analysis. The conclusions suggest that Wittgenstein’s thought, insofar as it maintains the distinction between norms, rules, reasons, etc. and facts, causes, etc., can hardly be matched with contemporary Naturalism and its reductionism without being tempted by the sublimations typical of the various forms of Platonism.

Environment generated quantum correlations in bipartite qubit-qutrit systems
Creators: name: Khan, Salman

description: The dynamics of entanglement and quantum discord for qubit-qutrit systems are studied in the presence of phase damping and amplitude damping noises. Both one way and two couplings of the marginal systems with the environments are considered. Entanglement sudden death is unavoidable under any setup, however, the required time span depends on the way of coupling. On the other hand, the dynamics of quantum discord strongly depends both on the nature of environment and on the number of dimensions of the Hilbert space of the coupled marginal system. We show that freezing and invariance of quantum discord, as previously reported in the literature, are limited to some special cases. Most importantly, it is noted that under some particular coupling the existence of environment can guarantee the generation of nonclassical correlations.

description: No abstracts are to be cited without prior reference to the author.We used a bio-physical model of the early life history of sandeel to investigate if sandeel larvae sampled at 6 stations in the northern North Sea could have originated from any of a small number of generally accepted spawning areas (off the Shetland and Orkney Isles, Moray Firth and Firth of Forth, off the Scottish east coast). Bio-physical modelling simulations were also used to investigate the likely destination of the larvae sampled in those stations and the potential origin of sandeels arriving to the Firth of Forth area, which sustained a sandeel fishery that has been closed since 2000. The question of the selfsustainability of the Firth of Forth sandeel populations is of considerable interest to the management of the sandeel fishery in the area. Our results suggest that most of the sandeel juveniles that settle in the area originated locally but that some degree of immigration from more northerly spawning areas was also possible.

description: The paper investigates a new hybrid synchronization called modified hybrid synchronization (MHS) via the active control technique. Using the active control technique, stable controllers which enable the realization of the coexistence of complete synchronization, anti-synchronization and project synchronization in four identical fractional order chaotic systems were derived. Numerical simulations were presented to confirm the effectiveness of the analytical technique.

BETWEEN ETHICS AND AESTHETICS. AGAINST THE MYTH OF REDUCTIVE THERAPEUTISM

Subjects: Wittgenstein, Morphology, Aesthetics, Quietism, Therapeutic Reading

description: My paper is about Andronico’s work on the connection between Ethics and Aesthetics in Wittgenstein’s later philosophy. In particular, I will focus on the role that her ideas play against the therapeutic reading of Wittgenstein’s philosophy. I will argue that, contrary to such a reading, the ethical tone of Wittgenstein’s philosophy should be understood as a consequence of aesthetical e-ducation, that is, the sharpening of the eye in order to see differently. I will show that (1) philosophy is a specific kind of theory and that (2) Cavell’s notion of the rediscovery of the ordinary does not properly grasp the ethical force of Wittgenstein’s remarks.
