description: Emerging evidence has exhibited an obvious decreased expression of miR-106a-5p in the ectopic endometrial tissue of endometriosis (EMS) patients. Thus far, the pathophysiological function of miR-106a-5p in EMS is unknown. A previous study showed an increased FOXC1 expression in the ectopic endometrial tissue of patients with EMS. Moreover, we found that there was a binding site of miR-106a-5p on the 3ʹUTR of FOXC1 through bioinformatics predictions. Hence, we speculated that miR-106a-5p might affect the development of EMS via targeting FOXC1. We first showed a decreased level of miR-106a-5p and an increased level of FOXC1 mRNA in ectopic endometrial tissues compared with normal tissues. Functionally, we transfected ectopic endometrial stromal cells (ESCs) with miR-106a-5p mimics or NC mimics and indicated an inhibitory role of miR-106a-5p on ESC proliferation, invasion, and migration. Mechanistically, FOXC1 was found to be a target gene of miR-106a-5p. To confirm whether miR-106a-5p exerted an inhibitory activity in ESCs via targeting FOXC1, miR-106a-5p mimic was co-transfected into ESCs with the FOXC1-plasmid or vector. We found that FOXC1 overexpression evidently reversed the results caused by a miR-106a-5p mimic in ESCs. Additionally, our results demonstrated that miR-106a-5p mimic inhibited the expression of p-Akt and p-PI3K. Collectively, these results revealed that miR-106a-5p inhibited the proliferative, migratory, and invasive ability of ESCs via directly binding to FOXC1, likely through the suppression of the PI3K and its downstream signaling pathway, which offered a potential and novel therapeutic strategy for EMS treatment.

description: It is challenging to search for high Tc superconductivity (SC) in transition metal elements wherein d electrons are usually not favored by conventional BCS theory. Here we report discovery of surprising SC up to 310 GPa with Tc above 20 K in wide pressure range from 108 GPa to 240 GPa in titanium. The maximum Tc^onset above 26 K and zero resistance Tc^zero of 21 K are record high values hitherto achieved among element superconductors. The Hc2(0) is estimated to be about 32 Tesla with coherence length 32 angstrom. The results show strong s-d transfer and d-band dominance, indicating correlation driven contributions to high Tc SC in dense titanium. This finding is in sharp contrast to the theoretical predications based on pristine electron-phonon coupling scenario. The study opens a fresh promising avenue for rational design and discovery of high Tc superconductors among simple materials via pressure tuned unconventional mechanism.

description: The spin Hall effect is investigated in a two-orbital tight-binding model on a honeycomb lattice. We show that the model exhibits three topologically-different insulating phases at half filling, which are distinguished by different quantized values of the spin Hall conductivity. We analytically determine the phase boundaries, where the valence and conduction bands touch with each other with forming the Dirac nodes at the Fermi level. The results are discussed in terms of the effective antisymmetric spin-orbit coupling. The relation to the Kane-Mele model and implications for a magnetoelectric effect are also discussed.

description: Conductivities are key material parameters that govern various types of transport (electronic charge, spin, heat etc.) driven by thermodynamic forces. Magnons, the elementary excitations of the magnetic order, flow under the gradient of a magnon chemical potential in proportion to a magnon (spin) conductivity $σ_{m}$. The magnetic insulator yttrium iron garnet (YIG) is the material of choice for efficient magnon spin transport. Here we report an unexpected giant $σ_{m}$ in record-thin YIG films with thicknesses down to 3.7 nm when the number of occupied two-dimensional (2D) subbands is reduced from a large number to a few, which corresponds to a transition from 3D to 2D magnon transport. We extract a 2D spin conductivity ($\approx1$ S) at room temperature, comparable to the (electronic) spin conductivity of the high-mobility two-dimensional electron gas in GaAs quantum wells at millikelvin temperatures. Such high conductivities offer unique opportunities to develop low-dissipation magnon-based spintronic devices.

description: In this position paper, we reflect on the end-user and stakeholder participation in the European eHealth project RE-SAMPLE. We outline the different roles of stakeholders that were involved in different activities during requirements elicitation and iterative development of the eHealth technology.

We reflect on these activities and the lessons learned in terms of the level of participation that took place, which level we could not reach yet (i.e., joint decision making) and how this could be improved.

description: How the transport properties of an extended system is affected by coupling to active reservoirs is a significant, yet virtually unexplored question. Here we address this issue in the context of energy transport between two active reservoirs connected by a chain of harmonic oscillators. The couplings to the reservoirs, which exert correlated stochastic forces on the boundary oscillators, lead to fascinating behavior of the energy current and kinetic temperature profile, which we compute exactly in the thermodynamic limit. We show that the stationary active current (i) changes non-monotonically as the activity of the reservoirs are changed, leading to a negative differential conductivity (NDC), and (ii) exhibits an unexpected direction reversal at some finite value of the activity drive. For the example of a dichotomous active force, we find the physical origin of the NDC using nonequilibrium response formalism. It turns out that the kinetic temperature profile remains uniform at the bulk, and can be expressed in a form similar to the thermally driven case. We show that despite this apparent similarity, no effective thermal picture can be consistently built in general. However, such a picture emerges in the small activity limit, where many of the well-known results are recovered.

description: Solute carrier family 39, member 1 (SLC39A1) is a member of the zinc-iron permease family and located to the cell membrane, acting as a zinc uptake transporter. However, the clinical impacts of SLC39A1 in early-stage hepatocellular carcinoma (EHCC) have not been defined. In this research, we compared the differential expression of SLC39A1 in EHCC and normal tissues based on tissue microarray, and the clinical significance of SLC39A1 in EHCC was evaluated as well. Compared with adjacent tissues, SLC39A1 was remarkably decreased in paired EHCC tissues. Besides, decreased SLC39A1 expression was significantly associated with several clinic-pathological features and serum biochemical indicators. Furthermore, Kaplan-Meier analysis exhibited that both overall survival (OS) and relapse-free survival (RFS) of patients with low expression of SLC39A1 were notably poorer than that of patients with high expression. Moreover, Cox regression analyses revealed that low expression of SLC39A1 was an independent prognostic factor for OS in patients with EHCC. Subgroup analysis also revealed beneficiary populations benefiting from the prognostic evaluation using SLC39A1 expression. Collectively, we summarized that downregulated expression of SLC39A1 is a worse prognostic factor for patients with EHCC, which can be used as a promising diagnostic and prognostic biomarker for EHCC.

description: Recently, a very beautiful measure of the unsharpness (fuzziness) of the observables is discussed in the paper [Phys. Rev. A 104, 052227 (2021)]. The measure which is defined in this paper is constructed via uncertainty and does not depend on the values of the outcomes. There exist several properties of a set of observables (e.g., incompatibility, non-disturbance) that do not depend on the values of the outcomes. Therefore, the approach in the above-said paper is consistent with the above-mentioned fact and is able to measure the intrinsic unsharpness of the observables. In this work, we also quantify the unsharpness of observables in an outcome-independent way. But our approach is different than the approach of the above-said paper. In this work, at first, we construct two Luder's instrument-based unsharpness measures and provide the tight upper bounds of those measures. Then we prove the monotonicity of the above-said measures under a class of fuzzifying processes (processes that make the observables more fuzzy). This is consistent with the resource-theoretic framework. Then we relate our approach to the approach of the above-said paper. Next, we try to construct two instrument-independent unsharpness measures. In particular, we define two instrument-independent unsharpness measures and provide the tight upper bounds of those measures and then we derive the condition for the monotonicity of those measures under a class of fuzzifying processes and prove the monotonicity for dichotomic qubit observables. Then we show that for an unknown measurement, the values of all of these measures can be determined experimentally. Finally, we present the idea of the resource theory of the sharpness of the observables.

description: By using a Hamiltonian based on the coupling through flux lines, we have calculated the interaction energy between two fermions via massless bosons as well as via massive particles. In the case of interaction via massless bosons we obtain an equivalent expression for the Coulomb's energy on the form, where is the fine structure constant. In the case of the interaction via massive particles we obtain that the interaction energy contains a term building the potential well. Taking into account the spin-spin interaction of the nucleons, we show that this interaction modulates the interaction potential through a cosine factor. The obtained results are in good agreement with experimental data, for example, of deuteron.

description: This research article emphasizes the significance of privacy in textual conversational data, specifically in the context of interactions between virtual assistants and users. While previous studies have primarily focused on named entities containing personally identifiable information, this research focuses on quasi-identifiers.´Due to the limited availability of conversational data in privacyinducing domains like healthcare, police force, and finance, the study employs a discrete prompting technique to engage large language models in generating conversations between hypothetical users and virtual assistants. To facilitate this process, this research introduces a straightforward interface. Additionally, a card-sorting experiment design is presented to involve participants in matching the conversations with persona cards representing hypothetical users. Subsequently, participants are asked to identify the information that aided them in making the appropriate matches. The experiment aims to outline the elements within textual data that can expose the identities of individuals engaged in conversations.

description: Außerschulische Bildungsangebote wie Makerspaces, MINT-Kurse (Mathematik, Informatik, Naturwissenschaften, Technik) und MINT-Ferienprogramme haben sich zu einem wichtigen Baustein der Förderung von Kindern und Jugendlichen entwickelt. Jedoch ist die Teilnahme an diesen Angeboten unter verschiedenen Bevölkerungsgruppen ungleich verteilt. Insbesondere Mädchen mit Zuwanderungsgeschichte sind in diesen Bereichen stark unterrepräsentiert. Das Verbundvorhaben MAKEitREAL der Hochschule Heilbronn, der Stadt Heilbronn und des Landesverbandes für naturwissenschaftlich-technische Jugendbildung Baden-Württemberg e. V. (natec) entwickelt ein partizipatives mobiles Makerspace-Angebot mit dieser Zielgruppe. Das Projekt strebt an, diese Gruppe an MINT-Fächer heranzuführen, bestehende MINT-Aktivitäten in der Region auszubauen und zu einem lebendigen Netzwerk zu verbinden. Es wird deutlich, dass die Bereitstellung von Partizipationsformaten unabhängig von der konkreten inhaltlichen Ausgestaltung durch die teilnehmenden Mädchen ein bedeutsames Signal der Wertschätzung und Zugehörigkeit darstellt, das den Zielen des Projekts dienlich sein kann.

description: Digital cameras transform sensor RAW readings into RGB images by means of their Image Signal Processor (ISP). Computational photography tasks such as image denoising and colour constancy are commonly performed in the RAW domain, in part due to the inherent hardware design, but also due to the appealing simplicity of noise statistics that result from the direct sensor readings. Despite this, the availability of RAW images is limited in comparison with the abundance and diversity of available RGB data. Recent approaches have attempted to bridge this gap by estimating the RGB to RAW mapping: handcrafted model-based methods that are interpretable and controllable usually require manual parameter fine-tuning, while end-to-end learnable neural networks require large amounts of training data, at times with complex training procedures, and generally lack interpretability and parametric control. Towards addressing these existing limitations, we present a novel hybrid model-based and data-driven ISP that builds on canonical ISP operations and is both learnable and interpretable. Our proposed invertible model, capable of bidirectional mapping between RAW and RGB domains, employs end-to-end learning of rich parameter representations, i.e. dictionaries, that are free from direct parametric supervision and additionally enable simple and plausible data augmentation. We evidence the value of our data generation process by extensive experiments under both RAW image reconstruction and RAW image denoising tasks, obtaining state-of-the-art performance in both. Additionally, we show that our ISP can learn meaningful mappings from few data samples, and that denoising models trained with our dictionary-based data augmentation are competitive despite having only few or zero ground-truth labels.

Το δείγμα της έρευνας απαρτίστηκε από ένα σύνολο 80 ασθενών το οποίο κατανεμήθηκε τυχαία σε τρεις πειραματικές ομάδες και μία ομάδα ελέγχου. Στους ασθενείς της πρώτης ομάδας. Ομάδα PNF (η=20), εφαρμόσθηκε η μέθοδος PNF, στους ασθενείς της δεύτερης ομάδας, Ομάδα ΑΣΚ., (η=20), εφαρμόσθηκαν ασκήσεις κοιλιακών και ραχιαίων μυών, στους ασθενείς της τρίτης ομάδας, Ομάδα ΗΛΕΚ., (η=20), εφαρμόσθηκε συμβατική φυσικοθεραπεία με τη χρήση φυσικών μέσων και στους ασθενείς της Ομάδας Ελέγχου (η=20) δεν έγινε καμία παρέμβαση. Αξιολογήθηκαν η ένταση του πόνου, η βελτίωση της λειτουργικότητας, οι αρνητικές και θετικές αντιδράσεις ψυχικής διάθεσης και το εύρος κίνησης κάμψης, έκτασης, πλάγιας κάμψης δεξιά και αριστερά της Σ.Σ. Οι αξιολογήσεις πραγματοποιήθηκαν σε τρεις χρονικές στιγμές: πριν την παρέμβαση, στο τέλος της παρέμβασης (8 εβδομάδες μετά) και τέσσερις μήνες μετά το τέλος της παρέμβασης. Η ανάλυση των δεδομένων πραγματοποιήθηκε με τη χρήση του στατιστικού προγράμματος SPSS® for Windows. Το επίπεδο σημαντικότητας για τον εντοπισμό διαφορών ορίστηκε ρ = 0.05. Σύμφωνα με τα αποτελέσματα των αναλύσεων διαπιστώθηκε σημαντική μείωση του πόνου, σημαντική βελτίωση της λειτουργικότητας και της κινητικότητας της Σ.Σ καθώς και σημαντική μείωση και αύξηση των αρνητικών και θετικών αντιδράσεων ψυχικής διάθεσης αντίστοιχα, σε όλες τις πειραματικές ομάδες μετά την παρέμβαση (2η μέτρηση). Κατά την ίδια μέτρηση, η Ομάδα Ελέγχου παρουσίασε σταθερή συμπεριφορά σε σχέση με την αρχική μέτρηση. Η αξιολόγηση των παραπάνω εξαρτημένων μεταβλητών 4 μήνες μετά την παρέμβαση (3η μέτρηση) έδειξε ότι η ομάδα PNF διατήρησε το αποτέλεσμα σε όλες τις εξαρτημένες μεταβλητές, η ομάδα ΑΣΚ. διατήρησε οριακά το αποτέλεσμα μόνο στη μεταβλητή «πόνος», η ομάδα ΗΛΕΚ. δε διατήρησε το αποτέλεσμα σε καμία εξαρτημένη μεταβλητή, ενώ η Ομάδα Ελέγχου εξακολουθούσε να διατηρεί σταθερή συμπεριφορά και κατά την τρίτη μέτρηση. Επιπρόσθετα παρουσιάστηκε σημαντική διαφορά μεταξύ της Ομάδας PNF και των υπόλοιπων ομάδων στη μεταβλητή «πόνος», «απώλεια λειτουργικότητας» ενώ παρουσιάστηκε σημαντική διαφορά της Ομάδας PNF με την ομάδα ΗΛΕΚ. και την Ομάδα Ελέγχου στις μεταβλητές «εύρος κίνησης κάμψης Σ.Σ », «αρνητικές και θετικές αντιδράσεις» ψυχικής διάθεσης. Λαμβάνοντας υπόψη το συνολικό αποτέλεσμα της παρούσας έρευνας συμπεραίνεται ότι οι ασκήσεις κινητικού ελέγχου μέσω της μεθόδου PNF μειώνουν τον πόνο, αυξάνουν τη λειτουργική ικανότητα και βελτιώνουν τη ψυχική διάθεση των ασθενών τόσο βραχυπρόθεσμα όσο και μακροπρόθεσμα. Η μέθοδος προτείνεται ως θεραπεία επιλογής για τους ασθενείς με χρόνιο οσφυϊκό πόνο.

description: Effect of the electric quadrupole moment, $Q$, is studied for positron-atom bound systems. It is demonstrated that for $Q >50$ a.u. the electric quadrupole potential is sufficiently strong to bind positron (or electron) even in the absence of the dipole polarization potential. Such large values of $Q$ are not known for atomic ground states, however, they exist in molecules and excited atoms. In the state $2s2p~^3P^o_2$ of beryllium, the quadrupole contribution makes difference between stable bound state and decay to Be$^+$ ion and positronium. In a majority of atoms the quadrupole contribution is small and can be neglected.

description: This paper provides an experimentally validated, probabilistic model of file behavior when consumed by a set of pre-existing parsers. File behavior is measured by way of a standardized set of Boolean "messages" produced as the files are read. By thresholding the posterior probability that a file exhibiting a particular set of messages is from a particular dialect, our model yields a practical classification algorithm for two dialects. We demonstrate that this thresholding algorithm for two dialects can be bootstrapped from a training set consisting primarily of one dialect. Both the (parametric) theoretical and the (non-parametric) empirical distributions of file behaviors for one dialect yield good classification performance, and outperform classification based on simply counting messages. Our theoretical framework relies on statistical independence of messages within each dialect. Violations of this assumption are detectable and allow a format analyst to identify "boundaries" between dialects. A format analyst can therefore greatly reduce the number of files they need to consider when crafting new criteria for dialect detection, since they need only consider the files that exhibit ambiguous message patterns.

Στην έρευνα, χρησιμοποιήθηκε το ερωτηματολόγιο SF-36 (Ware και συν., 1992, Pukrop και συν., 2003), που έχει βασιστεί σε ένα πολυδιάστατο μοντέλο υγείας και έχει ψυχομετρικές ιδιότητες. Επίσης για την αξιολόγηση της λειτουργικότητας επιλέχθηκαν, η δοκιμασία φυσικής απόδοσης Physical Performance test (Reuben & Siu, 1990), και το Ερωτηματολόγιο Λειτουργικής αξιολόγησης (McCusker και συν, 1999). Η γνωστική λειτουργία αξιολογήθηκε μέσω δοκιμασιών που αφορούσαν την ταχύτητα μεθόδευσης πληροφοριών (Schuhfried,G., 1996a) και την ικανότητα της προσοχής (Schuhfried, 1994). Σύμφωνα με τα αποτελέσματα της έρευνας, σε όλες τις αξιολογηθείσες μεταβλητές δεν παρατηρήθηκε στατιστικά σημαντική επίδραση του φύλου (ρ>.05), ενώ η ηλικία φάνηκε να έχει σημαντική κύρια επίδραση στην κινητική λειτουργικότητα - δοκιμασίας πεδίου (F(2, ΐ47)= 5,28, ρ75 ετών) σημείωσαν περισσότερα λάθη και μεγαλύτερη διάρκεια σε σχέση με τις αντίστοιχες επιδόσεις των νεότερων ατόμων, ηλικίας 65-69 ετών (ρ

description: The aims of this work were to investigate the impact of the heat treatment on the chemical composition (holocellulose, lignin and extractives) of different wood species, to characterise and quantify wood extractives and their composition by GC-MS analysis, to explore the effect of thermo vacuum process on the extractives content and composition, and to use molybdenum catalysts in order to increase the amount of recoverable extractives. The results showed that there was an increase in the amount of lignin and extractives, and a decrease in the amount of holocellulose following thermo treatment, in the treatment temperature function. Autoclave treatment of wood with water in the presence of some molybdenum catalysts can increase the amount of extracts, mostly in the presence of microcrystalline H3PMo12O40, but it reduces solubility. Soxhlet extraction of wood with ethanol/toluene mixture in the presence of H3PMo12O40 increased the amount of extractives and their solubility in chloroform, while in the presence of MoO3 only the solubility of extractives increased. GC-MS analysis of insoluble fraction showed the presence of myo-inositol and some simple carbohydrates, mainly ribose, xylose and glucose. GC-MS analysis of soluble fraction showed the presence of long-chain acids and fatty acid esters of 10-20 carbon atoms, mainly decanoic acid, hexadecanoic acid, and octadecanoic acid, which can be a source of fatty acids for biodiesel production. Following the heat treatment and the use of molybdenum catalysts, the increased amount of extractives allowed to obtain valuable amounts of biological and pharmaceutical active compounds. Furthermore, a new system for the complete separation of triglycerides and fatty acids of wood extractives has been developed: two-dimensional TLC through esterification with NaOCH3 and the use of AgNO3-TLC.

description: This paper describes the usage of the Elastic Stack as a powerful and flexible base for capturing, storing, analyzing, and visualizing log data, as well as conducting evaluations of public displays. Nowadays, public displays are an essential element in providing information from a variety of applications and systems. As 24/7 in-person observations are impossible, support is needed for evaluation of the usage for single unit installations as well as large-scale public display networks. A software-supported solution can automate the most common data collection steps and provide a common base for further evaluation. In this paper, we present an ongoing case study on our technical solution for supporting long-term 24/7 evaluation with the Elastic Stack in any kind of public display installation. The solution is based on a logging framework and the Elasticsearch, Logstash, and Kibana – tool stack. We present the technical solution, the requirements for our implementation, and possible evaluation approaches.

description: In Zukunft werden mobil und hybrid arbeitende Teams den Arbeitsalltag vieler Menschen weiterhin prägen. Dabei stellen sich aktuell noch viele Fragen wie bspw. die folgenden: Wie sollten effektive Arbeitspraktiken für die hybride Zusammenarbeit aussehen bzw. gestaltet werden? Wo stehen formalisierte und etablierte Arbeitsprozesse, informeller und in Verhandlung befindlicher Arbeit (wie z.B. articulation work) gegenüber? In diesem Workshop möchten wir neue Arbeitspraxen mit Fokus auf hybridem Arbeiten und Zusammenarbeit in kleinen und Mittelständischen Unternehmen (KMU) in den Blick nehmen und Fragestellungen entlang der Technologiegestaltung diskutieren. Dafür werden aktuelle empirische Befunde und Ansätze zusammengetragen, die neue, hybride Arbeits- und Kollaborationsformen untersuchen, die für kleine und mittlere Unternehmen einsetzbar sind. Damit stellt der Workshop ein Forum für den wissenschaftlichen Diskurs und die transdisziplinäre und praxisnahe Auseinandersetzung mit dem Thema dar. Die Inhalte der Beiträge reichen von empirischen Befunden, methodischen und ethischen Reflexionen, bis hin zu Praxisberichten. Der Workshop stellt eine Standortbestimmung dar, die den Ausgangspunkt für eine breitere Fachdiskussion zwischen Wissenschaft und Praxis dienen möchte, um aktuelle Fragestellungen offenzulegen und neue, praxisorientierte Impulse für das Forschungsgebiet zu schaffen.

description: Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second most common cause of cancer-related deaths worldwide. As immune response failure is the main factor in the occurrence and poor prognosis of HCC, our study aimed to develop an immune-associated molecular occurrence and prognosis predictor (IMOPP) of HCC. To that end, we discovered a 4-gene immune-associated gene signature: C–C motif chemokine ligand 14 (CCL14), kallikrein B1 (KLKB1), vasoactive intestinal peptide receptor 1 (VIPR1), and cluster of differentiation 4 (CD4). When tested on three cohorts as an immune-associated molecular occurrence predictor (IMOP), it had high sensitivity, specificity, and area under the receiver operating characteristics curve. When tested as an immune-associated molecular prognosis predictor (IMPP), it stratified the HCC prognosis for overall survival (Kaplan–Meier analysis, log rank P = 0.0016; Cox regression, HR = 1.832, 95% CI = 1.173–2.859, P = 0.008) and disease-free survival (Kaplan-Meier analysis, log rank P = 0.0227). IMPP also significantly correlated with the clinicopathological characteristics of HCC; integrating it with clinicopathological characteristics improved the accuracy of a nomogram for overall survival prediction (C-index: 0.7097 vs. 0.6631). In HCC tumor microenviroments, the proportion of CD8+ T cells significantly differed between IMOP-stratified groups. We conclude that IMOPP can potentially predict the occurrence of HCC in high-risk populations and improve prognostic accuracy by providing new biomarkers for risk stratification. In addition, we believe that the IMOP mechanism may be related to its effect on the proportion of CD8+ T cells in tumor-infiltrating lymphocytes.

description: Η άσκηση με αντιστάσεις συστήνεται για την καταπολέμηση της παχυσαρκίας και του σακχαρώδη διαβήτη. Ωστόσο, δεν είναι γνωστή η επίδραση της άσκησης με αντιστάσεις στη δραστικότητα της λιπάσης των τριακυλογλυκερολών. Σκοπός της παρούσας διατριβής ήταν η διερεύνηση της λιπόλυσης στο λιπώδη ιστό κατά την άσκηση με αντιστάσεις σε άτομα φυσιολογικού βάρους (ΑΦΒ) και παχύσαρκα άτομα (ΠΑ). Εννέα ΑΦΒ και 8 ΠΑ (υγιείς άνδρες) πραγματοποίησαν μια προπονητική μονάδα μυϊκής ενδυνάμωσης με αντιστάσεις. Η άσκηση είχε τη μορφή της κυκλικής προπόνησης, όπου πραγματοποιήθηκαν 3 κύκλοι των 10 ασκήσεων με ένταση 70 - 75% της μιας μέγιστης επανάληψης. Δείγματα λιπώδους ιστού από την περιοχή του γλουτού, με σκοπό τη μέτρηση της δραστικότητας της λιπάσης των τριακυλογλυκερολών και δείγματα φλεβικού αίματος, με σκοπό τον προσδιορισμό των συγκεντρώσεων νορεπινφρίνης, επινεφρίνης, ινσουλίνης, κορτιζόλης, γλυκαγόνης, ελεύθερων λιπαρών οξέων (ΕΛΟ), γλυκερόλης, γλυκόζης και γαλακτικού οξέος, λήφθηκαν πριν την άσκηση, στα 5 λεπτά άσκησης, στο τέλος του 1ου, 2ου και 3ου κύκλου. Σε όλη τη διάρκεια της άσκησης πραγματοποιούνταν προσδιορισμός των αναπνευστικών αερίων. Από την ανάλυση των δεδομένων διαπιστώθηκε αυξημένη ενεργειακή δαπάνη άσκησης στα ΑΦΒ και τα ΠΑ (2.9 ± 0.5, 2.6 ± 0.8 kcal kg-1 αντίστοιχα, ρ<0.05). Το αναπνευστικό πηλίκο κατά την άσκηση ήταν υψηλότερο στα ΠΑ έναντι των ΑΦΒ (0.98-1.03, 0.92-0.97 αντίστοιχα), υποδεικνύοντας χαμηλότερη οξείδωση λιπαρών οξέων στα ΠΑ. Η δραστικότητα της λιπάσης των τριακυλογλυκερολών αυξήθηκε 18 φορές στα 5 λεπτά άσκησης στα ΑΦΒ και 16 φορές στα ΠΑ στο τέλος του 1ου κύκλου και στη συνέχεια μειώθηκε παρά τη συνέχιση της άσκησης. Η καθυστερημένη λιπολυτική ανταπόκριση των ΠΑ διαπιστώθηκε και από τις συγκεντρώσεις των ΕΛΟ και της γλυκερόλης. Οι συγκεντρώσεις των κατεχολαμινών αυξήθηκαν και στις δύο ομάδες χωρίς να παρατηρηθούν διαφορές μεταξύ τους. Αντίθετα, η συγκέντρωση ινσουλίνης αυξήθηκε στα ΠΑ, όχι όμως και στα ΑΦΒ. Από τα αποτελέσματα καθίσταται σαφές πως η άσκηση με αντιστάσεις αυξάνει το ρυθμό λιπόλυσης και την ενεργειακή δαπάνη και στις δύο ομάδες. Ακόμη, διαπιστώνεται καθυστερημένη λιπολυτική ανταπόκριση από τα ΠΑ, η οποία ενδεχομένως να οφείλεται στην αύξηση της ινσουλίνης και να ευθύνεται για τη μικρότερη χρήση λιπιδίων.

description: We use an x-ray free-electron laser to study the ultrafast lattice dynamics following above band-gap photoexcitation of the incipient ferroelectric potassium-tantalate, \kto. % We use ultrafast near-UV (central wavelength 266\,nm and 50 fs pulse duration) laser light to photoexcite charge carriers across the gap and probe the ultrafast lattice dynamics by recording the x-ray diffuse intensity throughout multiple Brillouin zones using pulses from the Linac Coherent Light Source (LCLS) (central wavelength 1.3\,Å\, and $< 10$~fs pulse duration). We observe changes in the diffuse intensity that we conclude are associated with a hardening of the soft transverse optical and transverse acoustic phonon branches along $Γ$ to $X$ and $Γ$ to $M$. Using ground- and excited-state interatomic force constants from density functional theory (DFT) and assuming the phonon populations can be described by a time-dependent temperature, we fit the quasi-equilibrium thermal diffuse intensity to the experimental time-dependent intensity. We obtain the instantaneous lattice temperature and density of photoexcited charge carriers as a function of time delay. The DFT calculations demonstrate that photoexcitation transfers charge from oxygen $2p$ derived $π$-bonding orbitals to Ta $5d$ derived antibonding orbitals, further suppressing the ferroelectric instability and increasing the stability of the cubic, paraelectric structure.

description: The tumbling of a rigid rod in a shear flow is analyzed in the high viscosity limit. Following Burgers, the Master Equation is derived for the probability distribution of the orientation of the rod. The equation contains one dimensionless number, the Weissenberg number, which is the ratio of the shear rate and the orientational diffusion constant. The equation is solved for the stationary state distribution for arbitrary Weissenberg numbers, in particular for the limit of high Weissenberg numbers. The stationary state gives an interesting flow pattern for the orientation of the rod, showing the interplay between flow due to the driving shear force and diffusion due to the random thermal forces of the fluid. The average tumbling time and tumbling frequency are calculated as a function of the Weissenberg number. A simple cross-over function is proposed which covers the whole regime from small to large Weissenberg numbers.
