Set-Up of Bacterial Cellulose Production From the Genus Komagataeibacter and Its Use in a Gluten-Free Bakery Product as a Case Study (2019)

The use of bacterial cellulose (BC) in food systems is still limited due to production costs. Nine clones belonging to <i>Komagataeibacter hansenii</i>, <i>Komagataeibacter nataicola</i>, <i>Komagataeibacter rhaeticus</i>, <i>Komagataeibacter swingsii</i>, and <i>Komagataeibacter xylinus</i> species were screened for cellulose productivity in growth tests with five different carbon sources and three nitrogen sources. The water-holding and rehydration capacities of the purified cellulose were determined. The structure of the polymer was investigated through nuclear magnetic resonance (NMR) spectroscopy, attenuated total reflection Fourier transform infrared (ATR-FT-IR) spectroscopy and X-ray diffraction (XRD) analysis, and observed by scanning electron microscope (SEM). Natural mutants of <i>K. rhaeticus</i> LMG 22126<sup>T</sup> and <i>K. swingsii</i> LMG 22125<sup>T</sup> showed different productivity. The factors "bacterial isolate" and "nitrogen source" significantly affected the production of cellulose (<i>p</i> < 0.01) rather than the factor "carbon source" (<i>p</i> = 0.15). However, on average, the best conditions for increasing yield were found in medium containing glucose and peptone. Water-holding capacity (WHC) values ranged from 10.7 to 42.3 (<i>g</i> <sub>water</sub>/<i>g</i> <sub>cellulose</sub>) with significant differences among strains (<i>p</i> < 0.01), while the rehydration capacity varied from 4.2 to 9.3 (<i>g</i> <sub>water</sub>/<i>g</i> <sub>cellulose</sub>). A high crystallinity (64-80%) was detected in all samples with Iα fractions corresponding to 67-93%. The ATR-FT-IR spectra and the XRD patterns confirmed the expected structure. BC made by GVP isolate of <i>K. rhaeticus</i> LMG 22126<sup>T</sup>, which was the strain with the highest yield, was added to a gluten-free bread formulation. Results obtained from measurements of technological parameters in dough leavening and baking trials were promising for implementation in potential novel foods.
A Curated Experimental Compilation Analyzed by Theory Is More than a Review (2020)

Macromolecules is an exceptional resource in the field of polymer science and now publishes more than 1000 original articles a year that set the standard for scientific rigor and creative insights. Over the years, these individual contributions have combined to build the foundation of polymer science, broadly and inclusively defined. In addition to the individual articles, many of which are being celebrated in this series of editorials, Macromolecules has published invaluable reviews and perspectives. These scholarly contributions integrate the insights and results from numerous sources into a unified whole and often recommend future directions for the field. Novices and experts alike benefit from these works that capture topics from emerging discoveries to long-pondered topics and everything in between. To explore the importance of Macromolecules’ reviews and perspectives, we considered their influence on the field and found the 1994 review by Fetters et al. entitled “Connection between Polymer Molecular Weight, Density, Chain Dimensions, and Melt Viscoelastic Properties”1 to be a singularity. This review expertly curates and compiles a trove of data to build robust correlations between molecular characteristics and macroscopic viscoelastic properties of polymer melts, in the context of the tube model of entanglements.
New directions in tin sulfide materials chemistry (1998)

Tin sulfide-based materials can exist in many forms, ranging from discrete molecular species, to 1D chains, 2D dense and porous sheets and 3D open frameworks. The local coordination geometry around a tin center may vary from trigonal pyramidal, to tetrahedral, trigonal bipyramidal and octahedral, and around sulfur from terminal, v-shaped to trigonal pyramidal. The oxidation state may take +2 and +4 for tin and –2, –1, 0 for sulfur. The tin sulfide chemistry is further enriched by the catenation ability of sulfur. In addition, other elements (metal and non-metal) can be incorporated into the tin sulfide structures to yield ternary and quaternary materials. More importantly, using the recent developed ‘soft chemistry’ synthetic approach, various novel porous tin (poly)sulfide materials have emerged that display interesting optical, electrical and adsorption properties. Representative tin sulfide materials will be presented and discussed in this review to demonstrate the development of tin sulfide chemistry in the last three decades.
Sequence analysis of the MYC oncogene involved in the t(8;14)(q24;q11) chromosome translocation in a human leukemia T-cell line indicates that putative regulatory regions are not altered. (1988)

We have cloned the translocation-associated and homologous normal MYC alleles from SKW-3, a leukemia T-cell line with the t(8;14)(q24;q11) translocation, and determined the sequence of the MYC oncogene first exon and flanking 5' putative regulatory regions. S1 nuclease protection experiments utilizing a MYC first exon probe demonstrated transcriptional deregulation of the MYC gene associated with the T-cell receptor alpha locus on the 8q+ chromosome of SKW-3 cells. Nucleotide sequence analysis of the translocation-associated (8q+) MYC allele identified a single base substitution within the upstream flanking region; the homologous nontranslocated allele contained an additional substitution and a two-base deletion. None of the deletions or substitutions localized to putative 5' regulatory regions. The MYC first exon sequence was germ line in both alleles. These results demonstrate that alterations within the putative 5' MYC regulatory regions are not necessarily involved in MYC deregulation in T-cell leukemias, and they show that juxtaposition of the T-cell receptor alpha locus to a germ-line MYC oncogene results in MYC deregulation.
Phoebe: a collection of Phonon and Electron Boltzmann Equation solvers (2021)

Understanding the electrical and thermal transport properties of materials is critical to the design of all kinds of devices. Computational modeling nowadays allows for accurate in-silico predictions of materials properties, providing insights and guidelines for materials design. In order to accurately simulate materials transport properties, it is necessary to achieve an accurate description of electron and phonon properties, including the effect of interactions between carriers. While first-principles methods are capable of describing the microscopic properties of each carrier, using them to compute transport properties is still a formidable task, computationally demanding and memory intensive, as it requires carefully assembling all pieces of microscopic information to provide a picture of a macroscopic transport property. To address this challenge, we present a newly developed software package, Phoebe (a collection of PHOnon and Electron Boltzmann Equation solvers), which evaluates the effect of electron-phonon, phonon-phonon, boundary, and isotope scattering to predict the electron and phonon transport properties of materials. This open source C++ code combines MPI-OpenMP hybrid parallelization with GPU acceleration and distributed memory structures to manage computational cost, allowing Phoebe to effectively take advantage of contemporary computing infrastructures. Using this new framework, Phoebe can accurately and efficiently predict a wide range of transport properties such as the electrical, thermal conductivity, and thermoelectric performance, opening the way for the computational analysis of large and complex crystals.
Defect assessment of brazed steel components (2012)

In this work, the defect tolerance of brazed martensitic stainless steel joints subject to static or cycling loading was investigated in detail. Therefore, the quasi-static and cyclic mechanical behaviour of standard round specimens as well as of component like specimens with T-joint geometry under tensile loading conditions was characterized. In order to consider the effect of brazing defects on the structural integrity, typical defects with different sizes and geometries were introduced in the brazing zone. In addition, a numerical deformation analysis by means of finite elements was performed and compared with the experimental results. For static loading, a defect assessment procedure based on failure assessment diagrams (FAD) is proposed. For cycling loading, the life time of the defect containing specimens in the low cycle fatigue range can be estimated using K&lt;sub&gt;I&lt;/sub&gt;,N-curves with K&lt;sub&gt;I&lt;/sub&gt; being a notch stress intensity factor of the corresponding defect.
The multifactorial dynamic perfusion index: A predictive tool of cardiac surgery associated acute kidney injury (2022)

inclusion of dynamic indices of the quality of CPB improves the discrimination and calibration of the preoperative risk scores. The MDPI has better predictive ability than the existing static risk models and is a promising tool to integrate different factors into an advanced concept of goal-directed perfusion.
In Vivo Super-Resolution Cardiac Diffusion Tensor MRI: A Feasibility Study (2022)

A super-resolution (SR) technique is proposed for imaging myocardial fiber architecture with cardiac magnetic resonance. Images were acquired with a motion-compensated cardiac diffusion tensor imaging (cDTI) sequence. The heart left ventricle was covered with three stacks of thick slices, in short axis, horizontal and vertical long axes orientations, respectively. The three low-resolution stacks (2 × 2 × 8 mm<sup>3</sup>) were combined into an isotropic volume (2 × 2 × 2 mm<sup>3</sup>) by a super-resolution reconstruction. For in vivo measurements, each slice was acquired during a breath-hold period. Bulk motion was corrected by optimizing a similarity metric between intensity profiles from all intersecting slices in the dataset. The benefit of the proposed approach was evaluated using a numerical heart phantom, a physical helicoidal phantom with artificial fibers, and six healthy subjects. The SR technique showed improved results compared to the native scans, in terms of image quality and cDTI metrics. In particular, the myocardial helix angle (HA) was more accurately estimated in the physical phantom (HA = 41.5° ± 1.1°, with the ground truth being 42.0°). In vivo, it resulted in a sharper rate of change of HA across the myocardial wall (-0.993°/% ± 0.007°/% against -0.873°/% ± 0.010°/%).
Endocrine Characteristics of a Miniature Condition in Brahman Cattle: Circulating Concentrations of Some Growth-Related Hormones (1991)

Four miniature Brahman calves born in 1988 and 1989, along with four contemporary sex-matched Brahman control calves, were used in experiments to determine circulating concentrations of insulin-like growth factor I (IGF-I), growth hormone (GH), insulin, triiodothyronine, and thyroxine, and plasma glucose response to insulin challenge. The effect of plane of nutrition on plasma concentrations of IGF-I and insulin was also determined and a clinical screen of blood chemistries was conducted to determine effects of calf type. Plasma IGF-I was six times higher in control calves compared with miniature calves (209.0 vs 35.0 ng/ml; P = 0.001). However, miniature calves had mean plasma GH about six times higher (37.8 vs 6.2 ng/ml; P = 0.004) and had twice as many secretory episodes (9 vs 4.5; P = 0.005) over an 8-hr sampling period. Plasma concentrations of triiodothyronine (2.54 vs 1.80 ng/ml) and thyroxine (88.8 vs 56.2 ng/ml) were higher in control compared with miniature calves (P = 0.001), but concentrations of triiodothyronine and thyroxine in both calf types were within normal ranges. Although miniature calves displayed similar plasma glucose concentrations to controls, hypoglycemic response to insulin challenge tended to be greater in miniature calves. Nutritional regulation of circulating IGF-I appeared to be intact in miniature as well as control calves, as evidenced by a reduction in plasma IGF-I concentration following a decrease in plane of nutrition, and a subsequent increase in plasma IGF-I concentration following realimentation. Serum urea nitrogen was lower (P = 0.02) in control compared with miniature calves. These data describe a miniature condition in Brahman cattle that is manifested by apparently normal proportioned growth but small stature, and that is associated most notably with abnormally low circulating concentrations of IGF-I in the presence of paradoxically high circulating concentrations of GH. This condition appears to be similar to Laron dwarfism in humans, in which the low IGF-I is caused by an abnormality in the GH receptor.
Detection and time-tracking activation of a photosensitiser on live single colorectal cancer cells using Raman spectroscopy (2020)

Raman spectroscopy has been used to observe uptake, metabolism and response of single-cells to drugs. Photodynamic therapy is based on the use of light, a photosensitiser and oxygen to destroy tumour tissue. Here, we used single-cell Raman spectroscopy to study the uptake and intracellular degradation of a novel photosensitiser with a diphenylacetylene structure, DC473, in live single-cells from colorectal adenocarcinoma cell lines SW480, HT29 and SW620. DC473 was seen to predominantly accumulate in lipid droplets, showing higher accumulation in HT29 and SW620 cells than in SW480 cells, with a broader DC473 peak shifted to higher wavenumbers. DC473 activation and effects were tracked on live single-cells for 5 minutes. Upon exposure to UV light, the DC473 signal intensity dropped, with remaining DC473 shifting towards higher wavenumbers and widening, with a lifetime of approximately 50 seconds. Morphologically, SW480 and SW620 cells showed changes upon photodynamic therapy, whereas HT29 cells showed no changes. Morphological changes correlated with higher remaining DC473 signal after UV exposure. Our research suggests that DC473 forms aggregates within the cells that disaggregate following activation, showing the potential of Raman spectroscopy for the study of time-dependent single-cell pharmacodynamics.

Generating Conceptual Explanations for DL based ECG Classification Model (2022)

Deep learning techniques are being used for heart rhythm classification from ECG waveforms. Large networks using end-to-end learning such as convolutional neural networks are not easily interpretable by end-users such as doctors. This is because most of the state of art explainability techniques focus on explanations for data-scientists who have technical knowledge. However, end-users of such systems are normally doctors who are not familiar with the technical details of machine learning. Therefore, to address this gap, we propose a framework that provides explanation of ECG classification model in the language of clinicians. We leverage state of art knowledge-based systems to map domain concepts with outcomes of machine learning model. Our results show that domain concepts based explanations are useful for clinicians and can greatly reduce their cognitive load. This shall lead to larger deployment of these models in real world.
TERRESTRIAL HABITAT USE BY NESTING PAINTED TURTLES IN LANDSCAPES WITH DIFFERENT LEVELS OF FRAGMENTATION (2004)

As part of a comprehensive study of the effects of landscape change on the demography of aquatic turtles, we investigated the use of upland habitats by adult female painted turtles (Chrysemys picta) during the nesting season. We intentionally selected three ponds that were surrounded by a range of land uses and development (e.g., road density ranged from 0.9 to 7.3 km/km2). Terrestrial locations of transmitter-equipped turtles (n = 8) and unmarked females that were incidentally encountered (n = 10) were recorded to: i) determine the distance traveled to nesting habitat, ii) estimate the frequency that female turtles crossed roads to reach nesting habitat, and iii) examine how the abundance of potential nesting habitat affected distance traveled. Average straight-line distance from shoreline to the site a female turtle was encountered ranged from 54 to 115 m for the three ponds. We estimated that marked turtles made five road crossings and two turtles were killed by vehicles. Distance traveled was negatively correlated with the abundance of nesting habitat near a pond. Although adult females are probably less vulnerable when nesting occurs near pond shores, nests created near pond edges may be more vulnerable to predation. As a result, providing additional nesting habitat away from roads and other potential sources of mortality may enhance recruitment among local turtle populations.
Alternative Splicing Generates Putative Soluble CD83 Proteins That Inhibit T Cell Proliferation (2005)

CD83 is expressed on mature dendritic cells and activated lymphocytes and has been implicated to play an important role during T cell development in the thymus. In contrast, not much is known about the function of CD83 in the periphery. Soluble forms of CD83 have been detected in the serum, but neither the function nor the mechanism of how these soluble forms of CD83 are generated are fully understood. In this study, we report the identification of four different transcripts of CD83 in unstimulated PBMCs. Sequence analysis demonstrated that the longest form codes for transmembrane CD83 (CD83-TM), whereas the smaller transcripts are splice variants of full-length CD83, coding for putative soluble CD83 proteins. Stimulation of PBMCs with PHA, TNF-alpha, or LPS leads to the up-regulation of the full-length CD83 transcript and to a strong down-regulation of two of the three smaller transcripts. The smallest CD83 splice product can be translated efficiently into protein, and recombinant soluble CD83 shows a strong inhibitory effect on T cell proliferation in MLRs. Our results suggest that the constitutive production of soluble forms of CD83 under steady-state conditions may have an important function in regulating immune homeostasis.

Stochastic Bouncy Particle Sampler (2017)

We introduce a novel stochastic version of the non-reversible, rejection-free Bouncy Particle Sampler (BPS), a Markov process whose sample trajectories are piecewise linear. The algorithm is based on simulating first arrival times in a doubly stochastic Poisson process using the thinning method, and allows efficient sampling of Bayesian posteriors in big datasets. We prove that in the BPS no bias is introduced by noisy evaluations of the log-likelihood gradient. On the other hand, we argue that efficiency considerations favor a small, controllable bias in the construction of the thinning proposals, in exchange for faster mixing. We introduce a simple regression-based proposal intensity for the thinning method that controls this trade-off. We illustrate the algorithm in several examples in which it outperforms both unbiased, but slowly mixing stochastic versions of BPS, as well as biased stochastic gradient-based samplers.
Electrical control of reversible and permanent magnetization reorientation for magnetoelectric memory devices (2011)

We report giant reversible and permanent magnetic anisotropy reorientation between two perpendicular easy axes in a magnetoelectric polycrystalline Ni thin film and (011) oriented [Pb(Mg1/3Nb2/3)O3](1−x)-[PbTiO3]x (PMN-PT) heterostructure. The PMN-PT is partially poled prior to Ni film deposition to provide a remanent strain bias. Following Ni deposition and full poling of the sample, two giant remanent strains of equal and opposite values are used to reversibly and permanently reorient the magnetization state of the Ni film. These experimental results are integrated into micromagnetic simulation to demonstrate the usefulness of this approach for magnetoelectric based magnetic random access memory.
