description: Respiratory syncytial virus (RSV) is a common virus that can have varying effects ranging from mild cold-like symptoms to mortality depending on the age and immune status of the individual. We combined mathematical modelling using ordinary differential equations (ODEs) with measurement of RSV infection kinetics in primary well-differentiated human bronchial epithelial cultures in vitro and in immunocompetent and immunosuppressed cotton rats to glean mechanistic details that underlie RSV infection kinetics in the lung. Quantitative analysis of viral titre kinetics in our mathematical model showed that the elimination of infected cells by the adaptive immune response generates unique RSV titre kinetic features including a faster timescale of viral titre clearance than viral production, and a monotonic decrease in the peak RSV titre with decreasing inoculum dose. Parameter estimation in the ODE model using a nonlinear mixed effects approach revealed a very low rate (average single-cell lifetime > 10 days) of cell lysis by RSV before the adaptive immune response is initiated. Our model predicted negligible changes in the RSV titre kinetics at early times post-infection (less than 5 dpi) but a slower decay in RSV titre in immunosuppressed cotton rats compared to that in non-suppressed cotton rats at later times (greater than 5 dpi) in silico. These predictions were in excellent agreement with the experimental results. Our combined approach quantified the importance of the adaptive immune response in suppressing RSV infection in cotton rats, which could be useful in testing RSV vaccine candidates.

description: Calcific aortic valve disease (CAVD) is the most common etiology of acquired aortic valve disease. The early stage is characterized by thickening of the leaflets and none or marginal effect on the?mechanical properties of the valve, while the end stage disease is associated with impaired leaflet motion and resistances to blood flow. These conditions are known as aortic valve sclerosis (AVSc) and calcific aortic valve stenosis (AVS), respectively. AVSc is present in 25?30% of patients over 65 years of age and?in up to 40% of those over 75 years of age. Moreover, since AVSc hemodynamics are comparable to healthy controls, the presentation of the?disease is largely asymptomatic and almost 10% of these patients will progress to AVS within 10 years from the?diagnosis. Patients with severe AVS have a life expectancy of less than 10 years if untreated. Currently the main indication for AVS is aortic valve replacement (AVR). Over the last decade several clinical trials have been performed to halt the progression of CAVD with contradictory results. The early enthusiastic findings documenting a reduction in the progression of CAVD have been questioned by later randomized studies, which show substantial equivalence between treatments and placebo. It has been proposed that CAVD therapy may have been initiated too late in the course of the disease to have the desired effect. In conclusion, there is currently no definitive therapy supported by prospective and randomized studies to halt or delay the progression of CAVD, leaving AVR the treatment of choice. Therefore, the identification of high-risk patients at early stages of degeneration will open new perspectives for the appropriate timing of therapeutic intervention on future clinical trials. We implemented in vitro and ex vivo experiments to better characterize the early asymptomatic stage of CAVD and to evaluate osteopontin (OPN) as a potential biomarker in the progression of this degenerative disease. Moreover, we focused on OPN role in valve endothelial cells (VEC) migration, as well as valve interstitial cells (VIC) osteoblastic-like activation and biomineralization. Our results supported the correlation between CAVD progression and increased OPN levels in aortic valve tissue and blood. Interestingly, in advance stages of calcification, we demonstrated that the overexpressed OPN had different post-translational modification compared to healthy controls. Moreover, we analyzed bone morphogenetic protein 4 (BMP4) pathway and mechanical tensile stretch as cause of VIC osteogenic-like transdifferentiation and calcium accumulation.

description: The epidermal mucus of two ray species Dasyatis pastinaca and Raja miraletus was analyzed to identify biochemical compounds and explore their antimicrobial activities in order to point out their potential for human health-related applications. Epidermal mucus samples were extracted as acidic, crude and aqueous. Gas chromatography and gas chromatography-mass spectrometry (GC/MS) analyses were performed to determine the biochemical compounds of the mucus. The antibacterial and antifungal activities of the extracts obtained from mucus were analysed using the spectrophotometric broth microdilution method against bacterial (Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis and Enterococcus faecalis) and fungal (Candida albicans and Candida parapsilosis) strains. Gas chromatography and gas chromatography-mass spectrometry (GC/MS) analyses revealed the existence of several hydrocarbon-derived compounds and polycyclic aromatic hydrocarbons. In terms of antimicrobial activity, the highest detected MIC (minimum inhibitory concentration) value was 9.78 µL for the acidic extract of R. miraletus epidermal mucus (RmAC) against E. faecalis, while the lowest MIC value was 80.88 µL for the acidic extract of R. miraletus epidermal mucus (RmAC) against E. coli. The extracts of epidermal mucus from D. pastinaca and R. miraletus showed antimicrobial activities against all the used pathogens with varying degrees of efficiency and thus may be evaluated as a potential source of marine-derived antimicrobial components for biomedical purposes.

description: We study probability inequalities leading to tail estimates in a general semigroup $\mathscr{G}$ with a translation-invariant metric $d_{\mathscr{G}}$. (An important and central example of this in the functional analysis literature is that of $\mathscr{G}$ a Banach space.) Using our prior work [Ann. Prob. 2017] that extends the Hoffmann-Jorgensen inequality to all metric semigroups, we obtain tail estimates and approximate bounds for sums of independent semigroup-valued random variables, their moments, and decreasing rearrangements. In particular, we obtain the "correct" universal constants in several cases, extending results in the Banach space literature by Johnson-Schechtman-Zinn [Ann. Prob. 1985], Hitczenko [Ann. Prob. 1994], and Hitczenko and Montgomery-Smith [Ann. Prob. 2001]. Our results also hold more generally, in a very primitive mathematical framework required to state them: metric semigroups $\mathscr{G}$. This includes all compact, discrete, or (connected) abelian Lie groups.

description: Myocardin belongs to the SAP domain family of transcription factors and is expressed specifically in cardiac and smooth muscle during embryogenesis and in adulthood. Myocardin functions as a transcriptional coactivator of SRF and is sufficient and necessary for smooth muscle gene expression. However, the in vivo function of myocardin during cardiogenesis is not completely understood. Here we clone myocardin from chick embryonic hearts and show that myocardin protein sequences are highly conserved cross species. Detailed studies of chick myocardin expression reveal that myocardin is expressed in cardiac and smooth muscle lineage during early embryogenesis, similar to that found in mouse. Interestingly, the expression of myocardin in the heart was found enriched in the outflow tract and the sinoatrial segments shortly after the formation of linear heart tube. Such expression pattern is also maintained in later developing embryos, suggesting that myocardin may play a unique role in the formation of those cardiac modules. Similar to its mouse counterpart, chick myocardin is able to activate cardiac and smooth muscle promoter reporter genes and induce smooth muscle gene expression in nonmuscle cells. Ectopic overexpression of myocardin enlarged the embryonic chick heart. Conversely, repression of the endogenous chick myocardin using antisense oligonucleotides or a dominant negative mutant form of myocardin inhibited cardiogenesis. Together, our data place myocardin as one of the earliest cardiac marker genes for cardiogenesis and support the idea that myocardin plays an essential role in cardiac gene expression and cardiogenesis.

description: To identify species and priority areas for conservation, the DNA barcoding data set (partial sequences of the mitochondrial DNA cytochrome oxidase subunit I gene) of the family Apogonidae along the northwest coast of South China Sea was established. After identifying species by morphology and basic local alignment search tool, 21 cardinalfishes were found, and these species belong to six genera. Among 21 species, there were two first record species (Ostorhinchus nigrocinctus, O. gularis) and one uncertain status species (Ostorhinchus sp.). Average within-genus and within-family genetic distances were 17.12 and 20.55%, respectively. This DNA barcoding of the fish dataset reveals the need for taxonomic revisions of the family Apogonidae. Moreover, our study finds that the size of the specimen distribution of a given species and its intraspecific genetic diversity are positively related. The Beibu Gulf has a higher species diversity and intraspecific diversity than the other geographic regions. These results will help in the management of fisheries and the conservation of the fish biodiversity in South China Sea.

description: The morphology and morphometry of the sagittal otolith were compared for five Scorpaena species from the Sea of Marmara, Mediterranean Sea, Aegean Sea, and Black Sea. A total of 1700 specimens belonging to S. elongata (n = 300, TL = 9.2-23.6 cm), S. maderensis (n = 300, TL = 8.7-16.6 cm), S. notata (n = 400, TL = 9.5-22.9 cm), S. porcus (n = 400, TL = 8.4-25.1 cm), and S. scrofa (n = 300, TL = 9.5-33.4 cm) were collected during the 2019-2020 fishing season from the eight locations such as Antalya, Balıkesir, Çanakkale, Hatay, İzmir, Marmara Ereğlisi, Ordu and Şile in the four seas. 18 morphological and 10 morphometric otolith characters (for left and right sides) were compared in the five Scorpaena species (with male and female samples) from seventeen populations in the four seas. It was determined that the morphometric otolith characters examined in the study showed statistical differences between the Scorpaena species(P < 0.05). Among the morphological otolith characters, the dorsal and ventral margins are the most differentiated characters in the Scorpaena species. The morphological and morphometric characters of the otolith, which are highlighted in this study, could be adequately used as diagnostic features for the identification of Scorpaena diversity. This is the first study to compare five Scorpaena species sampled from eight locations in four seas by both otolith morphology and morphometry analyses.

description: Encoding readout methods based on different schemes have been successfully developed and tested with different types of position-sensitive detectors with strip-readout structures. However, how to construct an encoding scheme in a more general and systematic way is still under study. In this paper, we present a graph model for the encoding scheme. With this model, encoding schemes can be studied in a more systematic way. It is shown that by using an encoding readout method, a maximum of n(n-1)/2+1 strips can be processed with n channels if n is odd, while a maximum of (n(n-2))/2+2 strips can be processed with n channels if n is even. Furthermore, based on the model, the encoding scheme construction problem can be translated into a problem in graph theory, the aim of which is to construct an Eulerian trail such that the length of the shortest subcycle is as long as possible. A more general approach to constructing the encoding scheme is found by solving the associated mathematical problem. In addition, an encoding scheme prototype has been constructed, and verified with MRPC detectors.

description: Pre- and postnatal developmental studies of the lung have provided compelling evidence demonstrating multiple factors that orchestrate alveolar epithelial cell differentiation. The extent to which reactivation of certain developmental pathways in the adult might influence the course of differentiation of alveolar type 2 cells (AT2) into AT1 cells is not known. In this study, we examined selected members of the forkhead (Fox) family of transcription factors and the Wnt (wingless) family of signaling proteins for expression during human alveolar cell differentiation in vitro and determined their potential responses to sulfated components of extracellular matrix (ECM), like those shed from cell surfaces or found in basement membrane and modeled by heparin. Isolated adult human AT2 cells cultured over a nine day period were used to define the temporal profile of expression of targeted factors during spontaneous differentiation to AT1 cells. FoxA1 protein was up-regulated at early to intermediate time points, where it was strongly elevated by heparin. Gene expression of Wnt7A increased dramatically beginning on day 3 and was enhanced even further on days 7 and 9 by heparin, while protein expression appeared at days 7 and 9. These temporal changes of expression suggest that sulfated ECMs may act to enhance the increase in FoxA1 at the critical juncture when AT2 cells commence the differentiation process to AT1 cells, in addition to enhancing the increase in Wnt7A when the AT1 cell phenotype stabilizes. Collectively, these factors may act to modulate differentiation and stabilize cell numbers in the adult human pulmonary alveolus.

The individual, with a total lenght (TL) of 306 mm, was captured off Sines (Portugal) in March 2018, by a local fishing boat, using a seine net. This represents the first record of xanthism for this species and for any species of mackerel. The specimen is described here and compared with those of normal pigmentation. Considerations about the paucity of records for this or similar species are presented here, and the possibility of this condition being more frequent than previously thought is discussed

description: This study analyzed kinorhynch communities from the southern portion of Mobile Bay and the nearshore Alabama continental shelf. A multicorer was used to collect sediment samples from fourteen sites, specifically targeting the flow of freshwater efflux from the Mobile watershed. These sediment samples were analyzed for kinorhynch species, organic matter content, granulometry and trace metals. Kinorhynch specimens were examined via light microscopy and scanning electron microscopy and identified to species level for community analysis. Eleven species of kinorhynchs were recovered from thirteen sites. Four dominant species, Echinoderes augustae, E. bookhouti, E. spinifurca, and Leiocanthus langi were present, in agreement with an earlier survey of Alabama coastal kinorhynchs. Spearman correlations, PCA, and cluster analyses of kinorhynch communities, along with abiotic data, revealed a patchy distribution of kinorhynchs, organic matter and fine sediments in the path of freshwater efflux. Additionally, this study reports four new species records for the northern Gulf of Mexico. Résumé : Les communautés de Kinorynches de la baie de Mobile et du plateau continental de l'Alabama.

description: We consider certain strengthenings of property (T) relative to Banach spaces that are satisfied by high rank Lie groups. Let X be a Banach space for which, for all k, the Banach--Mazur distance to a Hilbert space of all k-dimensional subspaces is bounded above by a power of k strictly less than one half. We prove that every connected simple Lie group of sufficiently large real rank depending on X has strong property (T) of Lafforgue with respect to X. As a consequence, we obtain that every continuous affine isometric action of such a high rank group (or a lattice in such a group) on X has a fixed point. This result corroborates a conjecture of Bader, Furman, Gelander and Monod. For the special linear Lie groups, we also present a more direct approach to fixed point properties, or, more precisely, to the boundedness of quasi-cocycles. Without appealing to strong property (T), we prove that given a Banach space X as above, every special linear group of sufficiently large rank satisfies the following property: every quasi-1-cocycle with values in an isometric representation on X is bounded.

Year: 2022

description: The aim of this thesis is to determine diagnostic performance of machine learning in differentiating between atypical cartilaginous tumor (ACT) and high-grade chondrosarcoma (CS) based on radiomic features derived from magnetic resonance imaging (MRI) and computed tomography (CT). In chapter 2, the concept of radiomics of musculoskeletal sarcomas is introduced and a systematic review on radiomic feature reproducibility and validation strategies is conducted. In chapter 3, a preliminary study is performed to investigate the performance of MRI radiomics-based machine learning in discriminating ACT from high-grade CS, using a single-center cohort, in comparison with an expert radiologist. In chapter 4, the influence of interobserver segmentation variability on the reproducibility of CT and MRI radiomic features of cartilaginous bone tumors is assessed. In chapter 5, the performance of CT radiomics-based machine learning in discriminating ACT from high-grade CS of long bones is determined and validated using independent data from a multicenter cohort, compared to an expert radiologist. In chapter 6, the performance of MRI radiomics-based machine learning in differentiating between ACT and grade II CS of long bones is determined and validated using independent data from a multicenter cohort, in comparison with an expert radiologist. Finally, in chapter 7, the main results and implications of this thesis are summarized and discussed.

description: We calculated the electron mobility of 14 two dimensional semiconductors with composition of MX$_2$, where M (= Mo, W, Sn, Hf, Zr and Pt) is the transition metal, and X is S, Se and Te. We treated the scattering matrix by deformation potential approximation. Long wave longitudinal acoustical and optical phonon scatterings are included. Piezoelectric scattering in the compounds without inversion symmetry is also taken into account. We found that out of the 14 compounds, WSe$_2$, PtS$_2$ and PtSe$_2$, are promising regarding to the possible high electron mobility and finite band gap. The phonon limited mobility in PtSe$_2$ reaches about 3000 cm$^2$V$^{-1}$s$^{-1}$ at room temperature which is the highest among the compounds. The bandgap under the local density approximation is 1.25 eV. Our results can be a guide for experiments to search for better two-dimensional materials for future semiconductor devices.

Animal behaviour may mitigate the effects of ECEs, but field studies are rare because ECEs are infrequent and unpredictable. Hurricane Irma made landfall in southwestern Florida where we were monitoring white-tailed deer (Odocoileus virginianus seminolus) with GPS collars. We report on an opportunistic case study of behavioural responses exhibited by a large mammal during an ECE, mitigation strategies for reducing the severity of the ECE effects, and the demographic effect of the ECE based on known-fate of individual animals. Deer altered resource selection by selecting higher elevation pine and hardwood forests and avoiding marshes. Most deer left their home ranges during Hurricane Irma, and the probability of leaving was inversely related to home range area. Movement rates increased the day of the storm, and no mortality was attributed to Hurricane Irma. We suggest deer mobility and refuge habitat allowed deer to behaviourally mitigate the negative effects of the storm, and ultimately, aid in survival. Our work contributes to the small but growing body of literature linking behavioural responses exhibited during ECEs to survival, which cumulatively will provide insight for predictions of a species resilience to ECEs and improve our understanding of how behavioural traits offset the negative impacts of global climate change.

description: We investigate the relation between the dynamics of a single oscillator with delayed self-feedback and a feed-forward ring of such oscillators, where each unit is coupled to its next neighbor in the same way as in the self-feedback case. We show that periodic solutions of the delayed oscillator give rise to families of rotating waves with different wave numbers in the corresponding ring. In particular, if for the single oscillator the periodic solution is resonant to the delay, it can be embedded into a ring with instantaneous couplings. We discover several cases where stability of periodic solution for the single unit can be related to the stability of the corresponding rotating wave in the ring. As a specific example we demonstrate how the complex bifurcation scenario of simultaneously emerging multi-jittering solutions can be transferred from a single oscillator with delayed pulse feedback to multi-jittering rotating waves in a sufficiently large ring of oscillators with instantaneous pulse coupling. Finally, we present an experimental realization of this dynamical phenomenon in a system of coupled electronic circuits of FitzHugh-Nagumo type.

description: New records of four fish species from the Persian Gulf coasts of Oman are reported: Tenualosa toli (4 specimens), Plotosus limbatus (4 specimens), Velifer hypselopterus (5 specimens) and Minous inermis (3 specimens). All specimens were obtained during surveys by a trawler operating in the area during 2011. The present study is important in that it records for the first time a species of the family Veliferidae and adds a new location for the species of the families Clupeidae, Plotosidae and Synanceiidae. It is also important as it reports on the presence of established populations of the four species examined based on the catch of juvenile individuals.
Solid state synthesis of CdTe Quantum Dots through thermal precursors decomposition

Subjects: quantum dots

description: Poster Presentation at EURASIA 2018 (Rome 6-7 September 2018) The synthesis of colloidal photo-luminescent semiconductor quantum dots (QDs), belonging to II-VI groups, even from single source precursors is presented. Since three decades their synthesis has been pursued implementing new and easier synthetic conditions that standardize their production. In this work is reported the production of luminescent of CdS QDs in a polymeric film induced by laser processing. A film of PMMA doped with two types of precursors of cadmium carboxylate and tellurium phosphinate is deposited as a thin film to observe the formation of CdTe QDs. The CdTe formation is observed after thermal annealing for different time by means of UV-Vis and photoluminescence spectroscopy. The optical analysis showed the formation of CdTe QDs with size between 3 – 4 nm and with an emission photoluminescence included in the 540 650 nm region. These results pave the way for patterning of QDs by inducing thermal annealing in selected areas of the film.

description: The aim of this study was to determine the occurrence and distribution of gelatinous macrozooplankton in the southern Black Sea. The abundance and biomass of gelatinous organisms and their relationship with physical parameters were determined between March 2015 and February 2016 in the Sinop Peninsula of the southern Black Sea. Monthly samplings were conducted at six stations located in both the coastal and open sea. Gelatinous macrozooplankton was collected using vertical hauls (plankton net mouth opening 50 cm, mesh size 210 µm). The abundance and biomass of the gelatinous macrozooplankton increased in both summer and spring; the minimum values were recorded in winter. Maximum abundance was 43.33 m-2 (August 2015) in the open sea and 39.17 m-2 (July 2015) in the coastal areas. The highest biomass was 282.47 g.m-2 in coastal areas (April 2015) and 205.68 g.m-2 in the open sea (March 2015). We determined that the gelatinous macrozooplankton in the southern Black Sea decreased from 2002 to 2008. The distribution of species differed from the values observed in previous studies. No significant difference in abundance and biomass was observed between the open and coastal stations. Temperature was the main factor correlated with gelatinous macrozooplankton blooms.

description: Monitoring studies (2008-2019) were carried out and the influence of climatic factors on interannual changes in the length-weight and reproductive characteristics of Scorpaena porcus living on the Western shelf of the Crimea was investigated. It has been shown that the average annual linear size and weight of females and males increase in warmer years (correlation coefficient r = 0.80-0.86). It was found that the average long-term length of females exceeds the length of males by 1.1 cm (significance level α < 0.01). The dependence of the development of the reproductive system of S. porcus on the water temperature was found. Comparison with size, weight and reproductive parameters of S. porcus inhabiting the South-Eastern part of the Black Sea and Western shelf of the Crimea was carried out.

description: In this paper we consider the issue of the Froissart bound on the high energy behaviour of total cross sections. This bound, originally derived using principles of analyticity of scattering amplitudes, is seen to be satisfied by all the available experimental data on total hadronic cross sections. At strong coupling, gauge/gravity duality has been used to provide some insights into this behaviour. In this work, we find the subleading terms to the so-derived Froissart bound from AdS/CFT. We find that a $(\ln \frac{s}{s_0})$ term is obtained, with a negative coefficient. We see that the fits to the currently available data confirm improvement in the fits due to the inclusion of such a term, with the appropriate sign.
