description: Purpose of Review Cryopreservation and its associated freezing and thawing procedures-short "freeze-thawing"-are among the final steps in economically viable manufacturing and clinical application of diverse cellular therapeutics. Translation from preclinical proof-of-concept studies to larger clinical trials has indicated that these processes may potentially present an Achilles heel to optimal cell product safety and particularly efficacy in clinical trials and routine use. Recent Findings We review the current state of the literature on how cryopreservation of cellular therapies has evolved and how the application of this technique to different cell types is interlinked with their ability to engraft and function upon transfer in vivo, in particular for hematopoietic stem and progenitor cells (HSPCs), their progeny, and therapeutic cell products derived thereof. We also discuss pros and cons how this may differ for non-hematopoietic mesenchymal stromal/stem cell (MSC) therapeutics. We present different avenues that may be crucial for cell therapy optimization, both, for hematopoietic (e.g., effector, regulatory, and chimeric antigen receptor (CAR)-modified T and NK cell based products) and for non-hematopoietic products, such as MSCs and induced pluripotent stem cells (iPSCs), to achieve optimal viability, recovery, effective cell dose, and functionality of the cryorecovered cells. Summary Targeted research into optimizing the cryopreservation and freeze-thawing routines and the adjunct manufacturing process design may provide crucial advantages to increase both the safety and efficacy of cellular therapeutics in clinical use and to enable effective market deployment strategies to become economically viable and sustainable medicines.
Calibration Strategy And Status Of Tritium Purity Monitoring For Katrin

Year: 2018

description: The KATRIN (Karlsruhe Tritium Neutrino) experiment aims to measure the mass of the electron anti-neutrino with a sensitivity of 200 meV/c2 by measuring the spectrum of the beta electrons close to the kinematic endpoint region. For monitoring the isotopic composition in the gaseous tritium source a custom-made Laser-Raman-System (LARA) has been developed at the Tritium Laboratory Karlsruhe.

The two approaches used to calibrate the LARA system for trueness <3 % are: i) theoretical intensities together with a spectral intensity standard and ii) highly accurate gas mixtures. Latest efforts have improved the in-situ calibration via spectral standard with re-calculated theoretical uncertainties and uncertainty analysis. Recently, the TRIHYDE experiment has been setup which enables cross-checking of the calibration via gas mixtures of all six hydrogen isotopologues and further studies of systematic effects.

This poster presents the benefits and status of both complementary approaches.

description: Background In this retrospective routine data analysis, we investigate the number of emergency department (ED) consultations during the COVID-19 pandemic of 2020 in Germany compared to the previous year with a special focus on numbers of myocardial infarction and acute heart failure. Methods Aggregated case numbers for the two consecutive years 2019 and 2020 were obtained from 24 university hospitals and 9 non-university hospitals in Germany and assessed by age, gender, triage scores, disposition, care level and by ICD-10 codes including the tracer diagnoses myocardial infarction (I21) and heart failure (I50). Results A total of 2,216,627 ED consultations were analyzed, of which 1,178,470 occurred in 2019 and 1,038,157 in 2020. The median deviation in case numbers between 2019 and 2020 was - 14% [CI (- 11)-(- 16)]. After a marked drop in all cases in the first COVID-19 wave in spring 2020, case numbers normalized during the summer Thereafter starting in calendar week 39 case numbers constantly declined until the end of the year 2020. The decline in case numbers predominantly concerned younger [- 16%; CI (- 13)-(- 19)], less urgent [- 18%; CI (- 12)-(- 22)] and non-admitted cases [- 17%; CI (- 13)-(- 20)] in particular during the second wave. During the entire observation period admissions for chest pain [- 13%; CI (- 21)-2], myocardial infarction [- 2%; CI (- 9)-11] and heart failure [- 2%; CI (- 10)-6] were less affected and remained comparable to the previous year. Conclusions ED visits were noticeably reduced during both SARS-CoV-2 pandemic waves in Germany but cardiovascular diagnoses were less affected and no refractory increase was noted. However, long-term effects cannot be ruled out and need to be analysed in future studies. [GRAPHICS] .

Sterile Neutrino Decay
Creators: name: MOULAI, Marjon
Publisher: name: Zenodo
Year: 2018

description: Sterile neutrinos are hypothetical particles introduced to resolve anomalies in neutrino oscillation experiments. In a 3+1 sterile model, one heavier, mostly sterile neutrino mass eigenstate joins the three light, mostly active neutrino mass eigenstates. This simple model does not fit the world's data well. We consider an extension of the 3+1 scenario where the heaviest mass eigenstate decays. This would modify results of searches for sterile neutrinos, as well as allowed regions obtained from global fits.

Subjects: genetic algorithms; water systems; planning; optimization

description: Water supply systems are built ahead of time to meet future demand. Investments are made in steps to cover needs up to a planning horizon. The objective of long term planning optimization is to come up with the least cost scenario for investment decisions. Potential savings could be very significant and influence the decision to invest or not for a given project. These also allow the choice of a feasible and optimal alternative amongst several project scenarios. The present paper describes new approaches to long-term planning optimization using genetic algorithm search methods. The new approaches consist in determining the best phasing for longterm water projects. The formulation of the optimization problem is described along with three different genetic algorithm approaches. A case study based on the long-term water supply requirements of a region in North America is investigated. Finally, the results for the different GA formulations are presented and discussed.

Результати оцінки Індексу прозорості за категоріями у 2023 році свідчать, що спостерігається строката динаміка прозорості за категоріями Індексу, проте понад третини індикаторів Індексу - 2023 зберігається законодавче обмеження публічності.  Покращення Індексу прозорості з 2018 по 2021 рік була обумовлена розвитком нормативно-правової бази та рівнем регулювання інформаційної прозорості енергетичних ринків. В умовах воєнного стану Індекс прозорості значно зменшився і залишається на низькому рівні. Прозорість погіршується на трьох з п'яти енергетичних ринках (електроенергії, енергетичного вугілля та теплової енергії).

description: Purpose of Review Thalamic aphasia is a rare language disorder resulting from lesions to the thalamus. While most patients exhibit mild symptoms with a predominance of lexical-semantic difficulties, variations in phenotype have been described. Overall, the exact mechanisms of thalamic aphasia await empirical research. The article reviews recent findings regarding phenotypes and possible underlying mechanisms of thalamic aphasia. Recent Findings Variations in phenotype of thalamic aphasia may be related to different lesion locations. Overall, the thalamus' role in language is thought to be due to its involvement in cortico-thalamic language networks with lesioning of certain nuclei resulting in the diachisis of otherwise interconnected areas. Its possible monitoring function in such a network might be due to its different cellular firing modes. However, no specific evidence has been collected to date. While recent findings show a more distinct understanding of thalamic aphasia phenotypes and possible underlying mechanisms, further research is needed. Additionally, as standard language testing might oftentimes not pick up on its subtle symptoms, thalamic aphasia might be underdiagnosed.

description: The purpose of this systematic literature review is to provide an exhaustive summary of current research to explore the prospects of compassion-based approaches in treating persons with Schizophrenia Spectrum Disorders (SSD). Thereby, studies investigating the relationship between clinical parameters and self-compassion in SSD, as well as the acceptability, feasibility, and effects of compassion-based approaches for individuals with SSD were considered. The review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and checklist. Eight studies were included for qualitative synthesis. The results indicate an important role of self-compassion for several clinical parameters, including negative associations to positive symptoms, negative symptoms, cognitive disorganization, and emotional distress. All studies reported good acceptability and feasibility. Regarding the clinical effectiveness of compassion-based approaches, a variety of clinical benefits, such as improvements of mood, affect regulation, positive symptoms, negative symptoms, cognitive disorganization, and variables relating to psychological recovery were found in individuals with SSD. It is concluded that compassion-based approaches are a promising form of intervention in the treatment of SSD. However, further research, especially randomized controlled trials, in this field is needed to understand the full potential of compassion-based approaches for individuals with SSD.

description: Abstract. This paper describes the study of the possible measurement of parameters of the Stan­dard Model, which relate to CP violation with the ATLAS detector and the lifetime ratio of Ag and Bwhich is of great theoretical interest. This is done in two specific channels. The Bmesons and Ag baryon and its conjugate .Ag are observed with the ATLAS experi­ ment at LHC through their fully reconstructed decays **** and *****. The decays are reconstructed in 40 pb- 1 of data taken in 2010 and 1.2 fb-1 of data in 2011. The mass distributions obtained are fitted using an unbinned maximum likelihood fit. In order to extract the lifetime of the Bmeson a simultaneous unbinned maximum likelihood fit to the reconstructed Bmass and proper decay time is performed. The measured Band Ag!.i\g masses and the Blifetime are consistent with the world average values. Capability of the ATLAS detector to make a precise lifetime measurement was demonstrated. In order to under­ stand the detector performance, material effects, the background and interesting physics events, six Monte Carlo samples are generated for the signals and the background.

description: Purpose of Review Recent technical advances in computed tomography (CT) such as low-dose CT and dual-energy techniques open new applications for this imaging modality in clinical practice and for research purposes. This article will discuss the latest innovations and give a perspective on future developments. Recent Findings Low-dose CT has increasingly been used for assessing structural changes at the sacroiliac joints and the spine. It has developed into a method with similar or even lower radiation exposure than radiography while outperforming radiography for lesion detection. Despite being incompatible with low-dose scanning, some studies have shown that dual-energy CT can provide additional information that is otherwise only assessable with magnetic resonance imaging (MRI). However, it is unclear whether this additional information is reliable enough and if it would justify the additional radiation exposure, i.e. whether the performance of dual-energy CT is close enough to MRI to replace it in clinical practice. While the role of dual-energy CT in patients with axial spondyloarthritis remains to be established, low-dose CT has developed to an appropriate modality that should replace radiography in many circumstances and might supplement MRI.

description: The renewable energy sources are, and will be more and more, brought to function on the same site. However, they have not yet the subject of a real overall energy management strategy. As several systems rely on multiple energy sources, power distribution strategy must be implemented by matching the supply and the demand. The balance between production and consumption must be carefully conducted to ensure the availability of power. This paper advocates the use of the state flow approach as an alternative mean to manage the multi power source distribution for multiple supply systems by a load matching switch.

description: We study the effects of the identical leptons in the final state of the $B^+\to \ell^+ \ell^- \ell^+\barν_{\ell}$ decay. The amplitude of the process is described by the same form factors as the amplitude of the ${B\to \ell \ell \ell'\barν'_{\ell}}$ decay for non-identical leptons in the final state. However, the differential distributions are strongly different, as the ${B^+\to \ell^+ \ell^- \ell^+\barν_{\ell}}$ amplitude contains both the direct ($M_a$) and the exchange ($M_b$) diagrams. We calculate a number of the differential distirbutions. In particular, we propose an interesting observable that can be readily measured experimentally - the differential distribution over the invariant mass of the pair of leptons of the same charge, $\ell^+ \ell^+$. The good news is that the interference between $M_a$ and $M_b$, $d{\cal B}_{ab}$, is found to be at the level of less than 1\% in all considered differental distributions and therefore can be neglected in the full kinematical region of this decay.

description: Our poster will report on the ongoing development of a web-based software platform for collecting and analysing bio-bibliographic data for literary studies on GDR authors. It will present findings from the evaluation of a query editor that allows domain experts to compose complex queries involving relations between various entities of the underlying data model and constraints on the latter.
The editor's development follows a user-centered design methodology, which in our case employed interviews for finding out the information needs, overall technical affinity and experience with query interfaces of German literature domain experts. Based on the findings from the interviews, a prototype of the editor was developed. Its usability and user experience were evaluated, so far, with six domain experts using usability tests and a user experience questionnaire. Up to this point, the evaluation appears promising with respect to the platform's objective to support domain experts' research interests by providing user interfaces with good usability.

A new stochastic approach for advection-diffusion problems with uncertain parameters

description: We propose a new numerical method for solving advection-diffusion equations with uncertainty. The stochastic effects are introduced either in the velocity field or in the initial data resulting into a class of stochastic partial differential equations. Chaos polynomials are used to represent the stochastic processes in the considered model. This procedure, known also by spectral decomposition, results into a system of deterministic advection-diffusion equations. For each chaos coefficient, the method of characteristics is used to integrate in time its associated advection diffusion equation. Central finite differencing is implemented for the space discretization. The proposed method is verified for an advection-diffusion equation with known analytical solution. We also apply the method for simulation of the one-dimensional viscous Burgers equation. In both examples, the method demonstrates its ability to better maintain the shape of the solution in the presence of uncertainty and shocks.

description: Ground-based gravitational-wave interferometers could directly probe the existence of ultralight dark matter ($\mathcal{O}(10^{-14}-10^{-11})$ eV/$c^2$) that couples to standard-model particles in the detectors. Recently, many techniques have been developed to extract a variety of potential dark-matter signals from noisy gravitational-wave data; however, little effort has gone into ways to distinguish between types of dark matter that could directly interact with the interferometers. In this work, we employ the Wiener filter to follow-up candidate dark-matter interaction signals. The filter captures the stochastic nature of these signals, and, in simulations, successfully identifies which type of dark matter interacts with the interferometers. We apply the Wiener filter to outliers that remained in the LIGO/Virgo/KAGRA search for dark photons in data from the most recent observing (O3), and show that they are consistent with noise disturbances. Our proof-of-concept analysis demonstrates that the Wiener filter can be a powerful technique to confirm or deny the presence of dark-matter interaction signals in gravitational-wave data, and distinguish between scalar and vector dark-matter interactions.

Very long mixing times are then required for achieving a specific homogeneity level into the tank. Although the easiest way of removing such structures consist of increasing the impeller rotational speed, in many cases the turbulent regime cannot be achieved due to excessive media heating by viscous dissipation, torque limitations on the kinematic chain, and the costly power consumption. To alleviate these obstacles, alternate configurations specifically designed for operation in the laminar regime have been introduced. This paper deals with a review of these non-typical alternate configurations based mainly on off-centered impellers, multi-shaft equipment and planetary mixers. It will be shown that the performance of these systems paves the way to a new technological paradigm in laminar mixing.

Positive Feedback Trading and Stock Return Autocorrelation: The Case of Morocco
Creators: name: Achkir, M.
name: Charafi, A.
Publisher: name: Frontiers in Science and Engineering
Year: 2013
Subjects: positive feedback trading; autocorrelation; GARCH

description: This paper investigates the presence of positive feedback trading in the Casablanca stock exchange and measures the profitability and the effectiveness of selected herding strategies. The MADEX returns from 2004 to 2010 are analyzed, modeled, and forecasted for that purpose using linear autoregressive models, GARCH processes, and E-GARCH processes. Relying on the Sentana and Wadhwani’s positive feedback model, this paper explores the link between feedback trading, serial autocorrelations, and volatility. It presents supporting evidence on the persistence of serial autocorrelations in the index returns suggesting the prevailing influence of feedback trading activity on return dynamics. The signaling-based simulation results reveal that herd trading dominates the simple buy and hold strategy and the smart money investors’strategy both on daily and weekly bases. The results also unveil the impact of the day of trade on weekly trading outcomes, volatilities, and Sharpe ratios.

A Non Homogeneous Riemann Solver for Two-phase ShallowWater Flows
Creators: name: Benkhaldoun, Fayssal

Publisher: name: Frontiers in Science and Engineering
Year: 2013
Subjects: Shallow water equations; variable density; finite volume method; unstructured grids; two-phase flows.

description: The purpose of this research is to develop a simulation method for two-phase flows using shallow water equations. The hydraulics is modeled by the two-dimensional shallow water flows with variable horizontal density. The variation of density in the water flows can be attributed to the variation of thermal and salinity properties of the water. As an example of two-phase shallow water flows is the inclusion of the salty water from the sea into the fresh water of a river. Driving force of the phase separation and the mixing is the gradient of the density. For the numerical solution procedure we propose a non-homogeneous Riemann solver in the finite volume framework. The proposed method consists of a predictor stage for the discretization of gradient terms and a corrector stage for the treatment of source terms. The gradient fluxes are discretized using a modified Roe’s scheme using the sign of the Jacobian matrix in the coupled system. A well-balanced discretization is used for the treatment of source terms. The efficiency of the solver is evaluated by several test problems for two-phase shallow water flows. The numerical results demonstrate high resolution of the proposed non-homogeneous Riemann solver and confirm its capability to provide accurate simulations for two-phase shallow water equations under flow regimes with strong shocks.

description: The aim of this article is to measure and analyze the factors that determine the use of Information and Communication Technologies (ICT) by Moroccan School Teachers in their teaching practice. The measurement model is contextualized and based on the Unified Theory of Acceptance and Use of Technologies (UTAUT). The study used a descriptive analytical method. An online survey was emailed to 750 teachers working in primary and secondary schools in different regions of Morocco. A factorial analysis and Structural Equation Modeling were used to test and validate the model of Acceptance and Use of ICT by teachers. The results showed that there are two factors that influence the behavioral intention to accept and use ICT by MST in their teaching practice: Personal Self-Efficacy and Performance Expectancy. There are also three factors that influence their behavior regarding behavioral intention, Techno Pedagogical Supervision and Facilitating Conditions. However, an exogenous factor (the school social environment) has a negative impact on the intention and behavior of Moroccan teachers towards the acceptance and use of ICT in their teaching practice.

Subjects: calcium-hydroxyapatite; nickel loaded hydroxyapatite; niobium-nickel loaded hydroxyapatite; propane oxidative dehydrogenation

description: Nickel loaded calcium-hydroxyapatite (xNi/CaHAp) and niobium promoted xNi/CaHAp catalysts were synthesized and characterised by X-ray, FTIR, U.V-visible-NIR spectroscopies and temperature programmed reduction (H2-TPR). X-ray diffraction patterns of xNi/CaHAp showed that for nickel loadings above 5 wt.% Ni, diffraction lines belonging to bulk NiO start to appear. The average size of those nickel oxide particles is equal to 16, 23, and 35 nm for x = 10, 15 and 20 Wt.%, respectively. U.V-visible and TPR showed that the loaded nickel is hosted by octahedral and pseudo-octahedral sites. Calcium-hydroxyapatite loaded with different amounts of nickel and niobium promoted xNi/CaHAp catalysts were tested in oxidative dehydrogenation propane (ODH). The best performance was achieved with a nickel loading of x = 10%. The corresponding stationary conversion of propane is equal to 22% with a propylene yield of 13%. Addition of niobium to xNi/CaHAp decreases the global conversion but enhances the propylene selective and the stability of the catalyst with time on stream. The best results were obtained with 0.15 wt.% Nb. The propylene yield at stead state reaches 14% at 425°C.

description: Experimental and theoretical results are presented for double, triple, and quadruple photoionization of Si$^+$ and Si$^{2+}$ ions and for double photoionization of Si$^{3+}$ ions by a single photon. The experiments employed the photon-ion merged-beams technique at a synchrotron light source. The experimental photon-energy range 1835--1900 eV comprises resonances associated with the excitation of a $1s$ electron to higher subshells and subsequent autoionization. Energies, widths, and strengths of these resonances are extracted from high-resolution photoionization measurements, and the core-hole lifetime of K-shell ionized neutral silicon is inferred. In addition, theoretical cross sections for photoabsorption and multiple photoionization were obtained from large-scale Multi-Configuration Dirac-Hartree-Fock (MCDHF) calculations. The present calculations agree with the experiment much better than previously published theoretical results. The importance of an accurate energy calibration of laboratory data is pointed out. The present benchmark results are particularly useful for discriminating between silicon absorption in the gaseous and in the solid component (dust grains) of the interstellar medium.
