description: Compared to 7 healthy women, an altered beta2-adrenoceptor/cyclic adenosine monophosphate (cAMP) system has been observed in a combined study on both expression and function of beta2-adrenoceptors on peripheral blood leukocytes (PBL) of 7 atopic women suffering from acute seasonal rhinoconjunctivitis. A reduced affinity of the beta-adrenergic radioligand I-125 cyanopindolol to its binding site (equilibrium dissociation constant K(d) 6.4+/- 1.0 vs. 3.4 +/-0.6 pmol/l in controls; p < 0.05), a reduced sensitivity of the intracellular cAMP formation to isoprenaline (concentration necessary to achieve half-maximal effectiveness EC50 1,088.6 +/- 669.0 vs. 71.0 +/- 51.0 nmol/l in controls; p<0.01), and a reduced intracellular cAMP increase in response to isoprenaline (E(max) as a percentage of the basal cAMP content E0 117 +/- 3 vs. 145 +/- 8% E0 in controls; p<0.01) point to a subsensitivity of beta2-adrenoceptors. A reduced E0 (4.9 +/- 0.8 vs. 8.4 +/- 1.3 pmol/10(6) cells in controls; p< 0.05) suggests an increased activity of the cAMP-degrading enzyme phosphodiesterase. A reduced sympathetic tone in atopy was further confirmed by lower cAMP plasma concentrations (25.7 +/- 1.2 vs. 31.3 +/- 1.6 nmol/l in controls; p<0.05). The results indicate that more than just one mechanism are involved in the impairment of the PBL beta2-adrenoceptor/cAMP system in atopy.
Optimization of Process Parameters for Production of Honey powder from Ethiopian Honey By Spray-drying: a case study on its application in Bread
Creators: name: Abera Berhanu
Publisher: name: Zenodo
Year: 2014

description: The study was conducted with the objective of optimizing process parameters for production of honey powder by spray drying, characterizing the powder, and using it as a substitute for sugar in bread formulations.

Experimental design with inlet temperature (150 to 190 °C), feed flow rate (5–15ml/min), aspirator rate (80 to 100%) and gum Arabic ratio to liquid honey (20 to 60%) as independent variables was studied to investigate the effect on product responses. RSM was used to optimize process parameters. The spray dried honey powder was characterized for Moisture content, Particle size distribution, Hygroscopicity test and yield.

Four bread formulations were prepared with 100% of sugar liquid honey (LH), 50% substitution of sugar with honey powder (HP50%) and 100% honey powder (HP100%) and control. Breads produced from all four formulations were analyzed for loaf volume, weight loss, density, specific volume, moisture content, and texture
Nonasymptotic bounds for vector quantization in Hilbert spaces
Creators: name: Levrard, Clément

Year: 2014
Subjects: subject: Statistics Theory (math.ST)

description: Recent results in quantization theory show that the mean-squared expected distortion can reach a rate of convergence of $\mathcal{O}(1/n)$, where $n$ is the sample size [see, e.g., IEEE Trans. Inform. Theory 60 (2014) 7279-7292 or Electron. J. Stat. 7 (2013) 1716-1746]. This rate is attained for the empirical risk minimizer strategy, if the source distribution satisfies some regularity conditions. However, the dependency of the average distortion on other parameters is not known, and these results are only valid for distributions over finite-dimensional Euclidean spaces. This paper deals with the general case of distributions over separable, possibly infinite dimensional, Hilbert spaces. A condition is proposed, which may be thought of as a margin condition [see, e.g., Ann. Statist. 27 (1999) 1808-1829], under which a nonasymptotic upper bound on the expected distortion rate of the empirically optimal quantizer is derived. The dependency of the distortion on other parameters of distributions is then discussed, in particular through a minimax lower bound.

description: Mobile cloud computing is envisioned as a promising approach to augment computation capabilities of mobile devices for emerging resource-hungry mobile applications. In this paper, we propose a game theoretic approach for achieving efficient computation offloading for mobile cloud computing. We formulate the decentralized computation offloading decision making problem among mobile device users as a decentralized computation offloading game. We analyze the structural property of the game and show that the game always admits a Nash equilibrium. We then design a decentralized computation offloading mechanism that can achieve a Nash equilibrium of the game and quantify its efficiency ratio over the centralized optimal solution. Numerical results demonstrate that the proposed mechanism can achieve efficient computation offloading performance and scale well as the system size increases.

description: AI-based monitoring has become crucial for cloud-based services due to its scale. A common approach to AI-based monitoring is to detect causal relationships among service components and build a causal graph. Availability of domain information makes cloud systems even better suited for such causal detection approaches. In modern cloud systems, however, auto-scalers dynamically change the number of microservice instances, and a load-balancer manages the load on each instance. This poses a challenge for off-the-shelf causal structure detection techniques as they neither incorporate the system architectural domain information nor provide a way to model distributed compute across varying numbers of service instances. To address this, we develop CausIL, which detects a causal structure among service metrics by considering compute distributed across dynamic instances and incorporating domain knowledge derived from system architecture. Towards the application in cloud systems, CausIL estimates a causal graph using instance-specific variations in performance metrics, modeling multiple instances of a service as independent, conditional on system assumptions. Simulation study shows the efficacy of CausIL over baselines by improving graph estimation accuracy by ~25% as measured by Structural Hamming Distance whereas the real-world dataset demonstrates CausIL's applicability in deployment settings.

Publisher: name: Zenodo
Year: 2024

description: Environmental science is a transdisciplinary academic field that is sometimes defined as the study ofenvironmental problems, and other times defined as the study of environmental solutions. During mycareer, I had an earlier moment of realization to break away from the culture of studying environmentalproblems and move towards researching environmental solutions. Doing so opened the pathway tointerdisciplinary, trans-sector collaborations that led to tangible impacts related to solving the pollutioncrisis. Some realizations that occurred to me on this pathway were to i) embrace collaboration with societalactors that wants to make a positive change, ii) embrace the science-policy interface, iii) embracethe toxic-free hierarchy, iv) embrace the precautionary principle and v) embrace trans-disciplinary andtrans-sector collaborations. The way forward for applied environmental science is to develop tools tosolve the pollution crisis, and not simply to document the processes by which harmful impacts happen.

description: Background/context. Many first-year university students often lack the skills to identify appropriate learning strategies, and this may lead to increased burnout (Salmela-Aro et al., 2009). Although grit has been found to act as a protective factor against burnout, however, the effect of students’ approaches to learning (SAL) in explaining or mediating the relation between grit and burnout, is still unexamined among higher education students. Grit (broadly defined as the passion and perseverance in striving for long term goals; Duckworth, 2016), burnout, and SAL are important factors for succeeding in university education. The initiative/practice. This study examined if SAL acts as an intervening factor (mediator) between grit and burnout in a sample of 261 first-year students across various disciplines (e.g., Engineering, Health and Social Sciences, Infocomm Technology) at a Singapore-based university. Methods of evaluative data collection and analysis. Data was collected via self-report questionnaires at two-time points, beginning (grit and SAL) and end (burnout) of the first year. A mediation model employing Structural Equation Modelling (SEM) was performed, with SAL as a mediator between grit and burnout. Evidence of outcomes and effectiveness. The results revealed that unreflective approach mediated the relation between passion (i.e., grit) and cynicism (i.e., burnout), implying that adopting lower unreflective approaches explained why more passionate first-year students experienced lower cynicism. To reduce burnout, it is therefore important for educators to find practical ways to instil the passion in learning (e.g., cultivating gritty classroom culture, cultivating traits related to grit), in addition to reducing the focus on unreflective approaches to learning (e.g., fostering ability to monitor learning, relating learning to prior knowledge). Our study advances the understanding of how grit, SAL, and burnout are related, and potentially aids professionals at higher education intervene in the learning processes of first-year students.

description: A group of Scottish care leavers visited Denmark to undertake a comparative piece of research looking at the similarities and differences between care and leaving care provision in the respective countries. They interviewed Danish young people in two projects for care leavers and visited a range of other projects for young people in care. Whilst the lived experience of the two groups was broadly similar in relation to common themes of loss, stigma and levels of support in making the transition into young adulthood, the researchers found that the quality of relationships with staff/carers for the Danish young people was often better. The number of placement moves whilst in care was much lower for the Danes. The overall material and nurturing provision for Danish children and young people impressed the researchers.

description: In a mouse intercross with more than 500 animals and genome-wide gene expression data on six tissues, we identified a high proportion (18%) of sample mix-ups in the genotype data. Local expression quantitative trait loci (eQTL; genetic loci influencing gene expression) with extremely large effect were used to form a classifier to predict an individual's eQTL genotype based on expression data alone. By considering multiple eQTL and their related transcripts, we identified numerous individuals whose predicted eQTL genotypes (based on their expression data) did not match their observed genotypes, and then went on to identify other individuals whose genotypes did match the predicted eQTL genotypes. The concordance of predictions across six tissues indicated that the problem was due to mix-ups in the genotypes (though we further identified a small number of sample mix-ups in each of the six panels of gene expression microarrays). Consideration of the plate positions of the DNA samples indicated a number of off-by-one and off-by-two errors, likely the result of pipetting errors. Such sample mix-ups can be a problem in any genetic study, but eQTL data allow us to identify, and even correct, such problems. Our methods have been implemented in an R package, R/lineup.

description: We investigate the influence of close neighbor galaxies on the properties of supernovae (SNe) and their host galaxies using 56 SNe located in pairs of galaxies with different levels of star formation (SF) and nuclear activity. The mean distance of type II SNe from nuclei of hosts is greater by about a factor of 2 than that of type Ibc SNe. The distributions and mean distances of SNe are consistent with previous results compiled with the larger sample. For the first time it is shown that SNe Ibc are located in pairs with significantly smaller difference of radial velocities between components than pairs containing SNe Ia and II. We consider this as a result of higher star formation rate (SFR) of these closer systems of galaxies.

description: The problem of a steady forced convection thermal boundary-layer past a flat plate with a prescribed surface heat flux is investigated both analytically and numerically. In view of the present formulation, the governing equations reduce to the well-know Blasius similarity equation and to the full boundary-layer energy equation with two parameters: Prandtl number and surface heat flux parameter. The range of existence of solutions is considered. The asymptotic solutions are derived and compared with the numerical solutions of the full boundary-layer equation. A very good agreement between these asymptotic solutions and numerical simulations are found in the range of Prandtl numbers considered.

description: The rise of the social web shifts personal identity management to the online world. As a result, personal information is persistently available to all of a user's contacts without distinguishing between dierent contexts such as Work and Leisure. Personal information being available to audiences outside the intended context violates contextual integrity and poses a threat to users' privacy. We argue that a formal description and a conceptualization of the problem scope is required to systematically address current challenges of personal identity management in online social settings. Based thereupon, we propose assisted social identity management to support the user in nding segregated audiences among his contacts as a rst step to advance from the current situation and sketch further improvements. We evaluate our approach using real-world data, demonstrating the feasibility of our proposal.

description: A new description of strange attractor systems through three geometrical and dynamical invariants is provided. They are the correlation dimension ($\mathcal{D}$) and the correlation entropy ($\mathcal{K}$), both having attracted attention over the past decades, and a new invariant called the correlation concentration ($\mathcal{A}$) introduced in the present study. The correlation concentration is defined as the normalised mean distance between the reconstruction vectors, evaluated by the underlying probability measure on the infinite-dimensional embedding space. These three invariants determine the scaling behaviour of the system's Rényi-type extended entropy, modelled by Kummer's confluent hypergeometric function, with respect to the gauge parameter ($ρ$) coupled to the distance between the reconstruction vectors. The entropy function reproduces the known scaling behaviours of $\mathcal{D}$ and $\mathcal{K}$ in the 'microscopic' limit $ρ\to\infty$ while exhibiting a new scaling behaviour of $\mathcal{A}$ in the other, 'macroscopic' limit $ρ\to 0$. The three invariants are estimated simultaneously via nonlinear regression analysis without needing separate estimations for each invariant. The proposed method is verified through simulations in both discrete and continuous systems.

description: Rapid urbanization in Nigeria has led to significant public health challenges, including overcrowding, limited access to healthcare, environmental pollution, and socioeconomic disparities. This article examines the multifaceted factors contributing to health challenges in urban Nigeria and explores strategies, successes, and recommendations for addressing them. Statement of the Problem Urban areas in Nigeria face complex public health challenges, including inadequate healthcare infrastructure, environmental pollution, and social inequalities, which pose significant barriers to improving health outcomes and wellbeing for urban residents.

Qualitative method of  study was employ in comprehensive review of existing literature, including peer-reviewed research articles, government reports, and policy documents, to analyze the public health challenges in urban Nigeria and identify successful interventions, community-driven projects, and partnerships between government and non-governmental organizations (NGOs) for health improvement.

The study find out that the public health challenges in urban Nigeria are shaped by socioeconomic disparities, infrastructure inadequacies, environmental pollution, and a lack of healthcare infrastructure and resources. These challenges exacerbate health inequities and hinder efforts to improve health outcomes in urban areas. Successful public health initiatives, such as mobile health clinics, mass immunization campaigns, and community-driven health projects, have demonstrated the effectiveness of targeted interventions, community engagement, and partnerships between government and NGOs in improving health outcomes and fostering community empowerment. The study  conclude by recommending  addressing public health challenges in urban Nigeria include strengthening integrated health systems, empowering communities, promoting health education and awareness, fostering multi-electoral partnerships, investing in infrastructure and environmental sustainability, addressing social determinants of health, promoting research and innovation, building resilience and preparedness, and promotion  equity and inclusivity

description: We point out that for a range of parameters, the flux of DM may be stopped significantly by its interactions with the Earth. This can significantly degrade the sensitivity of direct detection experiments to DM candidates with large interactions with terrestrial nuclei. We find that a significant region of parameter space remains unconstrained for DM $\lesssim $ a few GeV. For DM candidates with moderate levels of stopping power, the flux of DM may be blocked from below but not above a detector thereby producing a novel daily modulation. This can be explored by low threshold detectors placed on the surface or in shallow sites in the south hemisphere.

Revealing the evolution of freshwater fish viruses in the Murray-Darling Basin, Australia

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Viruses account for the majority of emerging infectious diseases globally. Understanding how viruses establish infections in multiple hosts through a process called cross-species transmission is therefore central to our understanding of virus evolution and emergence. The advent of meta-transcriptomics opened up an alternative view of the vertebrate virosphere, showing that many host species harbour an abundance and diversity of viruses without causing disease. This is particularly true for fish, which have proven to serve as a rich source of virus diversity. Despite this, there is virtually no knowledge on the viruses that circulate in freshwater fishes across Australia, including those associated with biological invasions. The ongoing invasion of the common carp (Cyprinus carpio) in the Murray-Darling Basin has led to research into biological control measures, such as the use of cyprinid herpesvirus 3 (CyHV-3). The lack of described viruses in the Murray-Darling Basin raises questions regarding the safety of CyHV-3, as the consequences of cross-species transmission into native fishes are uncertain. In this thesis, I performed a meta-transcriptomic viral survey of invasive and native fishes across the Murray-Darling Basin. I identified 15 potentially novel viruses that could be assigned to 13 virus families. Notably, I revealed a marked lack of virus exchange between invasive and native fishes, particularly those viruses found in common carp. To my knowledge, this is the largest survey of freshwater fish viruses globally, covering over 2,200 km of the river system. The viruses identified in this thesis greatly facilitate biological control plans in Australia and enhances our understanding of the ecology and evolutionary history of vertebrate viruses more generally.

description: Short baseline neutrino oscillation experiments have shown hints of the existence of additional sterile neutrinos in the eV mass range. Such sterile neutrinos are incompatible with cosmology because they suppress structure formation unless they can be prevented from thermalising in the early Universe or removed by subsequent decay or annihilation. Here we present a novel scenario in which both sterile neutrinos and dark matter are coupled to a new, light pseudoscalar. This can prevent thermalisation of sterile neutrinos and make dark matter sufficiently self-interacting to have an impact on galactic dynamics and possibly resolve some of the known problems with the standard cold dark matter scenario. Even more importantly it leads to a strongly self-interacting plasma of sterile neutrinos and pseudoscalars at late times and provides an excellent fit to CMB data. The usual cosmological neutrino mass problem is avoided by sterile neutrino annihilation to pseudoscalars. The preferred value of $H_0$ is substantially higher than in standard $Λ$CDM and in much better agreement with local measurements.

description: Ensembles of nitrogen-vacancy (NV) centers are used as sensors to detect NMR signals from micron-sized samples at room temperature. In this scenario, the regime of large magnetic fields is especially interesting as it leads to a large nuclear thermal polarisation -- thus, to a strong sensor response even in low concentration samples -- while chemical shifts and J-couplings become more accessible. Nevertheless, this regime remains largely unexplored owing to the difficulties to couple NV-based sensors with high-frequency nuclear signals. In this work, we circumvent this problem with a method that maps the relevant energy shifts in the amplitude of an induced nuclear spin signal that is subsequently transferred to the sensor. This stage is interspersed with free-precession periods of the sample nuclear spins where the sensor does not participate. Thus, our method leads to high spectral resolutions ultimately limited by the coherence of the nuclear spin signal.

description: We selected and studied 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies to investigate the dependence of galaxies' integral parameters, star-formation (SF) and active galactic nuclei (AGN) properties on kinematics of pairs, their structure and large-scale environments. Projected radial separation Dp and perturbation level P are better measures of interaction strength than dV. The latter correlates with the density of large-scale environment and with the morphologies of galaxies. Both galaxies in a pair are of the same nature, the only difference is that MRK galaxies are usually righter than their neighbors. Specific star formation rates (SSFR) of galaxies in pairs with smaller Dp or dV is in average 0.5 dex higher than that of galaxies in pairs with larger Dp or dV. Closeness of a neighbor with the same and later morphological type increases the SSFR, while earlier-type neighbors do not increase SSFR. Major interactions/mergers trigger SF and AGN more effectively than minor ones. The fraction of AGNs is higher in more perturbed pairs and pairs with smaller Dp. AGNs typically are in stronger interacting systems than star-forming and passive galaxies. There are correlations of both SSFRs and spectral properties of nuclei between pair members.

description: Ιn recent years, specialized and alternative forms of tourism have emerged as the primary choice for travelers. The need to move away from mass tourism has resulted in the rapid growth of these sustainable tourism modalities. One such destination is the island of Kythera, which affords visitors the opportunity to explore the beauty of nature and culture through a plethora of activities, primarily centered around hiking and an exceptionally developed network of trails. This thesis examines hiking tourism as a pivotal factor in achieving sustainable tourism development on the island of Kythera. It analyzes the significance of hiking tourism as an alternative tourism model that contributes to averting overtourism and ensuring a balanced flow of tourism throughout the year. The focus is also on the development, significance, and restoration of the island's trails, which play a vital role in preserving its natural and cultural heritage. Furthermore, the thesis explores how hiking tourism can bolster the local economy, mitigate labor fluctuations, and counteract depopulation on the island. To achieve the objectives of this thesis, empirical quantitative research was conducted using a simple random sampling method, facilitated through an online questionnaire distributed to stakeholders involved in the island's tourism industry. The survey respondents expressed their views on the contribution of hiking to the island's tourism product and the key factors that could further advance hiking tourism. Lastly, the research aimed to ascertain the extent to which hiking tourism can contribute to the island's sustainable tourism development.

Mithilfe von Gruppendiskussionen und einer Auswertung mit der dokumentarischen Methode wurden kollektive Erfahrungsräume und geteilte Handlungsorientierungen rekonstruiert. Analysiert wurden Passagen aus vier Gruppendiskussionen, welche für diese Arbeit in drei Sprachen (deutsch, französisch, englisch) und zwei Formaten (per zoom und in Präsenz) erhoben wurden. Insgesamt nahmen junge Erwachsene aus fünf europäischen Ländern teil (Österreich, Belgien, Deutschland, Spanien, Ungarn). In den Ergebnissen zeigen sich eine einengende Ubiquität des Smartphones (und der Welt, die es vermittelt) und eine systematische Abhängigkeit der Nutzer*innen von seinen Funktionen. Durch seine permanente Nähe und sein permanentes Potenzial zu stören greift das Smartphone in die Räumlichkeit und Zeitlichkeit seiner Nutzer*innen ein und formatiert sie. Dort wo Einengung und Abhängigkeit überwunden werden, zeigen sich Erleichterung und Empowerment. Diese Ergebnisse deuten darauf hin, dass eine selbstbestimmbare Distanz der Nutzer*innen zu ihrem Smartphone notwendig ist, damit sie ihre Handlungsfähigkeit und Spontaneität bewahren.

description: Azlocillin (Securopen) and mezlocillin (Baypen) were given to 3 healthy subjects as intravenous infusion. The dose of 4 g was administered to each person within 5, 15, and 30 min in a randomized crossover design. Using HPLC the unchanged penicillin antibiotics were determined quantitatively, their metabolites were assessed qualitatively. The same specimens were also studied by means of a bioassay (agar diffusion technique). Both methods yielded similar serum and urine concentrations besides the urinary excretion of azlocillin. Here the bioassay measured higher amounts indicating an antibacterially active metabolite being excreted in the urine. No dependence upon infusion time was found. Since both drugs were tested with the same dosis in the same subjects, their pharmacokinetic parameters could be compared: mezlocillin, being more lipophilic than azlocillin, showed a higher volume of distribution and therefore lower serum concentrations. Renal clearance was the same for both drugs, but mezlocillin was excreted to a smaller extent in the urine. Higher total clearance and shorter elimination half-life of mezlocillin indicate a greater extrarenal elimination. The results suggest fast application of both penicillins. There is no pharmacokinetic reason for a prolongation of infusion times.

description: We recover the gradient of a scalar conductivity defined on a smooth bounded open set in $\mathbb{R}^d$ from the Dirichlet to Neumann map arising from the $p$-Laplace equation. For any boundary point we recover the gradient using Dirichlet data supported on an arbitrarily small neighbourhood of the boundary point. We use a Rellich-type identity in the proof. Our results are new when $p \neq 2$. In the $p = 2$ case boundary determination plays a role in several methods for recovering the conductivity in the interior.

description: This paper studies a novel spatial auto-correlation model of voter uncertainty across districts. We use the Moran $I$ index to measure the auto-correlation of Shannon, relative Shannon, Tsallis and relative Tsallis entropies of regional electoral outcomes with respect to geographic adjacency, proximity and sectarian adjacency. Using data from the Lebanese parliamentary elections, we find strong geographic and gravitational adjacency correlations. More importantly, there is a notably strong correlation in sectarian adjacency in both $2018$ and $2022$ elections, with a very high level of confidence. This result asserts the dominance of the sectarian factor in Lebanese politics. We also introduce the method of maximized general entropy estimation that allows us to determine the Markov transition matrix of voters between consecutive elections.

description: Peripheral mononuclear leukocytes (pMNL) bear a population of beta 2-adrenoceptors. Radioreceptor assays with (-)-125Iodocyanopindolol (125I-CYP) are often used to determine the expression of these hormone receptors under physiological and pathological conditions. Doubts on the occurrence of just one class of binding sites as well as the availability of new laboratory equipment prompted us to revise the procedure employed for investigation of these receptors. pMNL were harvested from venous human blood by density centrifugation with LymphopaqueR, LymphoprepR, or FicollR yielding immunologically distinct pMNL fractions. Receptor binding assays were performed semi-automatically with 125I-CYP in the range from 0.6-600 pmol/l. Analysis of the data (modified affinity spectra, Scatchard plot) revealed two classes of binding sites (high- and low affinity binding). The binding isotherms were sigmoidal in the concentration range from 0.6-3.0 pmol/l. Parameters estimated for the high affinity binding site may vary by a factor of 10, depending on the mathematical model employed.

description: The FAIR (Findable, Accessible, Interoperable, Reusable) data principles [1] are powerful guidelines, which form the foundation of research data management (RDM) concepts. These concepts are demanded by an increasing number of publishers, institutes and funding agencies. Nevertheless, in detail, the FAIR Data Principles are a set of technical definitions, that require a high level of technical and interdisciplinary knowledge and need to be adapted for each discipline. This results in a complex and time-consuming task, which is challenging to realise for experimenters in their everyday lab work.
 With BioCatHub we are working on a platform for research data management. It was created to help experimenters to realise RDM based on the FAIR data principles in biocatalysis with three central concepts. First, BioCatHub (retrobiohub.org) works as data collection platform and provides a user interface, which helps experimenters to describe experimental procedures in a wizard like structure. Secondly, BioCatHub contains data integration functions to query online databases like SabioRK, Brenda and autocomplete entries for the experimenters during the data collection process. Third, BioCatHub writes collected data to the machine-readable file format Enzyme markup language (EnzymeML) [2]. This enables the possibility to collect, share or store information about biocatalytic experiments. This can for example help to improve the biocatalytic production of industrial and pharmaceutical molecules like metaraminol [3].
 BioCatHub therefore provides a concept for research data management conceptualised on the FAIR data principles, adapted for the use in biocatalysis and designed to be used by experimenters in biocatalysis.

description: This article studies the group generated by automorphisms of the projective space of dimension $n$ and by the standard birational involution of degree $n$. Every element of this group only contracts rational hypersurfaces, but in odd dimension, there are simple elements having this property which do not belong to the group. Geometric properties of the elements of the group are given, as well as a description of its intersection with monomial transformations.

description: The effects of an intramuscular application of fetal mesenchym (Resistocell) in mice with acute radiation injury was investigated. A single dose of 80 mg/kg body weight one day after radiation exposure (LD70/30, 635 cGy) showed significant therapeutic effects. Further experiments are recommended in order to improve and explain the reported results.

description: Current robotic minimally invasive surgery (RMIS) platforms provide surgeons with no haptic feedback of the robot's physical interactions. This limitation forces surgeons to rely heavily on visual feedback and can make it challenging for surgical trainees to manipulate tissue gently. Prior research has demonstrated that haptic feedback can increase task accuracy in RMIS training. However, it remains unclear whether these improvements represent a fundamental improvement in skill, or if they simply stem from re-prioritizing accuracy over task completion time. In this study, we provide haptic feedback of the force applied by the surgical instruments using custom wrist-squeezing devices. We hypothesize that individuals receiving haptic feedback will increase accuracy (produce less force) while increasing their task completion time, compared to a control group receiving no haptic feedback. To test this hypothesis, N=21 novice participants were asked to repeatedly complete a ring rollercoaster surgical training task as quickly as possible. Results show that participants receiving haptic feedback apply significantly less force (0.67 N) than the control group, and they complete the task no faster or slower than the control group after twelve repetitions. Furthermore, participants in the feedback group decreased their task completion times significantly faster (7.68%) than participants in the control group (5.26%). This form of haptic feedback, therefore, has the potential to help trainees improve their technical accuracy without compromising speed.

description: In testing an overall null hypothesis, it does not matter whether to permute the response variables (Y) while keeping the predictors fixed or to permute the predictor variables (X) while keeping the response variables fixed. However, in weighted (univariate and multivariate) regression and in partial tests these options yield different results. This paper defines and evaluates by simulation ordinary and standardized versions of X- and Y-permutation for tests which encompass the existing Double Semi-Partialling, here called Collins-Dekker, and Freedman-Lane permutation methods. When the error variance is inversely proportional to the weights, the standardized permutation methods (which use standardized residuals) are most powerful, as expected, but otherwise they can be extremely liberal. In contrast, ordinary X-permutation (which permutes the residuals of X given any covariates ‘as is’) is by far the most robust against variability in the weights and against the error variance-weight relationship and is thus recommended for general use.

description: We present an uncertainty-relation-type quantum benchmark for continuous-variable (CV) quantum channels that works with an input ensemble of Gaussian distributed coherent states and homodyne measurements. It determines an optimal trade-off relation between canonical quadrature noises unbeatable by entanglement breaking channels and refines the notion of two quantum duties introduced in the original papers of CV quantum teleportation. It can verify the quantum-domain performance for all one-mode Gaussian channels.We also address the case of stochastic channels and the effect of asymmetric gains.
