Utilization of seawater for cost-effective cultivation and harvesting of Scenedesmus obliquus.
Abstract Microalgae hold great promise as a source of biofuels and biochemicals. The main obstacles to their industrial application are the high cultivation and downstream costs related to media and harvesting. In the work, we explored the multiple potentials of seawater to address key issues relating to the cultivation of Scenedesmus obliquus. Seawater can sufficiently replace some of the key elements in BG11 medium such as MgSO4, CaCl2, and NaCO3, and its use can significantly reduce the quantity of water required for the preparation of culture media. Among our results, the total chlorophyll content in cells grow...

Tissue-Engineered Tracheal Reconstruction Using Mesenchymal Stem Cells Seeded on a Porcine Cartilage Powder Scaffold.
Abstract Tissue engineering using a biocompatible scaffold with various cells might be a solution for tracheal reconstruction. We investigated the plausibility of using mesenchymal stem cells (MSCs) seeded on a porcine cartilage powder (PCP) scaffold for tracheal defect repair. PCP made with minced and decellularized porcine articular cartilage was molded into a 5 × 12 mm (height × diameter) scaffold. MSCs from young rabbit bone marrow were expanded and cultured with the PCP scaffold. After 7 weeks culture, the tracheal implants were transplanted on a 5 × 10 mm tracheal defect in six rabbits. 6 and 10 ...

Automatic detection of wakefulness and rest intervals in actigraphic signals: A data-driven approach
Actigraphy is an useful tool for evaluating the activity pattern of a subject; activity registries are usually processed by first splitting the signal into its wakefulness and rest intervals and then analyzing each one in isolation. Consequently, a preprocessing stage for such a splitting is needed. Several methods have been reported to this end but they rely on parameters and thresholds which are manually set based on previous knowledge of the signals or learned from training. This compromises the general applicability of this methods. (Source: Medical Engineering and Physics)

Escherichia coli persistence kinetics in dairy manure at moderate, mesophilic, and thermophilic temperatures under aerobic and anaerobic environments.
Abstract To assess Escherichia coli (E. coli) persistence in dairy manure, bench scale experiments were conducted under aerobic and anaerobic environments. The changes in E. coli levels in dairy manure were assessed at moderate (25 °C), mesophilic (37 °C), and thermophilic (52.5 °C) temperatures. The inactivation of E. coli at moderate, mesophilic, and thermophilic temperatures were described by linear regression equations. Subsequently, double-exponential kinetic models were developed to describe the E. coli decay curves under aerobic and anaerobic environments. The kinetics models were used to estimate E. c...

Microbial community analysis of a full-scale DEMON bioreactor.
In this study, bacterial community structure of a full-scale DEMON bioreactor located at the Apeldoorn wastewater treatment plant was analyzed using pyrosequencing. This technique provided a higher-resolution study of the bacterial assemblage of the system compared to other techniques used in lab-scale DEMON bioreactors. Results showed that the DEMON bioreactor was a complex ecosystem where ammonium oxidizing bacteria, anammox bacteria and many other bacterial phylotypes coexist. The potential ecological role of all phylotypes found was discussed. Thus, metagenomic analysis through pyrosequencing offered new perspectives o...

Strategies to Direct the Enrichment, Expansion, and Recruitment of Regulatory Cells for the Treatment of Disease.
Abstract Disease and injury perturb the balance of processes associated with inflammation and tissue remodeling, resulting in positive feedback loops, exacerbation of disease and compromised tissue repair. Conversely, under homeostatic healthy conditions, these processes are tightly regulated through the expansion and/or recruitment of specific cell populations, promoting a balanced steady-state. Better understanding of these regulatory processes and recent advances in biomaterials and biotechnology have prompted strategies to utilize cells for the treatment and prevention of disease through regulation of inflammat...

The role of coupled resistance–compliance in upper tracheobronchial airways under high frequency oscillatory ventilation
A large eddy simulation (LES) based computational fluid dynamics (CFD) study was conducted to investigate lung lobar ventilation and gas exchange under high frequency oscillatory ventilation conditions. Time-dependent pressure coupled with the airways resistance and compliance (R&C) were imposed as boundary conditions (BCs) in the upper tracheobronchial tree of patient-specific lung geometry. The flow distribution in the left and right lungs demonstrated significant variations compared to the case in which traditional BCs based on mass flow rate fractions was used and is in agreement with the in vivo data available in the ...

Improved Iterative Hard- and Soft-Reliability Based Majority-Logic Decoding Algorithms for Non-Binary Low-Density Parity-Check Codes
Non-binary low-density parity-check (LDPC) codes have some advantages over their binary counterparts, but unfortunately their decoding complexity is a significant challenge. The iterative hard- and soft-reliability based majority-logic decoding algorithms are attractive for nonbinary LDPC codes, since they involve only finite field additions and multiplications as well as integer operations and, hence, have significantly lower complexity than other algorithms. In this paper, we propose two improvements to the majority-logic decoding algorithms. Instead of the accumulation of reliability information in the existing majority...

On Prime Root-of-Unity Sequences With Perfect Periodic Correlation
In this paper, perfect root-of-unity sequences (PRUS) with entries in $alpha_p = {x in {BBC} ,vert, x^p =1}$ (where $p$ is a prime) are studied. A lower bound on the number of distinct phases that are used in PRUS over $alpha_p$ is derived. We show that PRUS of length $L geq p(p-1)$ must use all phases in $alpha_p$. Certain conditions on the lengths of PRUS are derived. Showing that the phase values of PRUS must follow a given difference multiset property, we derive a set of equations (which we call the principal equations) that give possible lengths of a PRUS over $alpha_p$ together with their phase distributions. The use...

A Comprehensive Approach to Universal Piecewise Nonlinear Regression Based on Trees
In this paper, we investigate adaptive nonlinear regression and introduce tree based piecewise linear regression algorithms that are highly efficient and provide significantly improved performance with guaranteed upper bounds in an individual sequence manner. We use a tree notion in order to partition the space of regressors in a nested structure. The introduced algorithms adapt not only their regression functions but also the complete tree structure while achieving the performance of the “best” linear mixture of a doubly exponential number of partitions, with a computational complexity only polynomial in the...

Proper Quaternion Gaussian Graphical Models
In this paper, we extend Gaussian graphical models to proper quaternion Gaussian distributions. The properness assumption reduces the number of unknowns by a factor of four while graphical models reduce the number of degrees of freedom via sparsity. Each of the methods allows accurate estimation using a small number of samples. To enjoy both gains, we show that the proper quaternion Gaussian inverse covariance estimation problem is convex and has a closed form solution. We proceed to demonstrate that the additional sparsity constraints on the inverse covariance matrix also lead to a convex problem, and the optimizations ca...

A Damper Driven Robotic End-Point Manipulator for Functional Rehabilitation Exercises After Stroke
Stroke survivors may benefit from robotic assistance for relearning of functional movements. Current assistive devices are either passive, limited to only two dimensions or very powerful. However, for reach training, weight compensation and a little assistance with limited power is sufficient. We designed and evaluated a novel three-dimensional robotic manipulator, which is able to support the arm weight and assist functional reaching movements. Key points of the design are a damper-based drive train, giving an inherently safe system and its compact and lightweight design. The system is force actuated with a bandwidth of u...
