Food Emulsion Gels from Plant-Based Ingredients: Formulation, Processing, and Potential Applications

Recent advances in the understanding of formulations and processing techniques have allowed for greater freedom in plant-based emulsion gel design to better recreate conventional animal-based foods. The roles of plant-based proteins, polysaccharides, and lipids in the formulation of emulsion gels and relevant processing techniques such as high-pressure homogenization (HPH), ultrasound (UH), and microfluidization (MF), were discussed in correlation with the effects of varying HPH, UH, and MF processing parameters on emulsion gel properties. The characterization methods for plant-based emulsion gels to quantify their rheological, thermal, and textural properties, as well as gel microstructure, were presented with a focus on how they can be applied for food purposes. Finally, the potential applications of plant-based emulsion gels, such as dairy and meat alternatives, condiments, baked goods, and functional foods, were discussed with a focus on sensory properties and consumer acceptance. This study found that the implementation of plant-based emulsion gel in food is promising to date despite persisting challenges. This review will provide valuable insights for researchers and industry professionals looking to understand and utilize plant-based food emulsion gels

Lattice distortion inducing exciton splitting and coherent quantum beating in CsPbI3 perovskite quantum dots

Anisotropic exchange-splitting in semiconductor quantum dots (QDs) results in bright-exciton fine-structure-splitting (FSS) important for quantum information processing. Direct measurement of FSS usually requires single/few QDs at liquid-helium temperatures, because of its sensitivity to QD size and shape, whereas measuring and controlling FSS at an ensemble-level seem to be impossible unless all the dots are made to be nearly the same. Here we report strong bright-exciton FSS up to 1.6 meV in solution-processed CsPbI3 perovskite QDs, manifested as quantum beats in ensemble-level transient absorption at liquid-nitrogen to room temperatures. The splitting is robust to QD size and shape heterogeneity, and increases with decreasing temperature, pointing towards a mechanism associated with orthorhombic distortion of perovskite lattice. Effective-mass-approximation calculations reveal an intrinsic "fine-structure gap" that agrees well with the observed FSS. This gap stems from an avoided crossing of bright-excitons confined in orthorhombically-distorted QDs that are bounded by the pseudocubic {100} family of planes

Extending Conditional Dependencies with Built-in Predicates

This paper proposes a natural extension of conditional functional dependencies (CFDs [1]) and conditional inclusion dependencies (CINDs [2]), denoted by CFDps and CIND(p)s, respectively, by specifying patterns of data values with not equal, <, <=, >, and >= predicates. As data quality rules, CFDps and CIND(p)s are able to capture errors that commonly arise in practice but cannot be detected by CFDs and CINDs. We establish two sets of results for central technical problems associated with CFD(p)s and CIND(p)s. (a) One concerns the satisfiability and implication problems for CFD(p)s and CIND(p)s, taken separately or together. These are important for, e.g. deciding whether data quality rules are dirty themselves, and for removing redundant rules. We show that despite the increased expressive power, the static analyses of CFD(p)s and CIND(p)s retain the same complexity as their CFDs and CINDs counterparts. (b) The other concerns validation of CFD(p)s and CIND(p)s. We show that given a set Sigma of CFD(p)s and CIND(p)s on a database D, a set of SQL queries can be automatically generated that, when evaluated against D, return all tuples in D that violate some dependencies in Sigma. We also experimentally verified the efficiency and effectiveness of our SQL based error detection techniques, using real-life data. This provides commercial DBMS with an immediate capability to detect errors based on CFD(p)s and CIND(p)s.973 program [2014CB340300, 2012CB316200, 2014CB340302]; NSFC [61322207, 61133002]; Guangdong Innovative Research Team Program [2011D005]; Shenzhen Peacock Program [1105100030834361]; EPSRC [EP/J015377/1, EP/M025268/1]; NSF III [1302212]; Google Faculty Research Award; [ERC-2014-AdG 652976]SCI(E)[email protected]; [email protected]; [email protected]; [email protected]; [email protected]

Nao-Xue-Shu

Aim. To determine one traditional Chinese medicine (TCM) Nao-Xue-Shu oral liquid which protects and improves secondary brain insults (SBI) in hypertensive cerebral hemorrhage (HCH). Methods. 158 patients with HCH were divided into routine clinical medicine plus Nao-Xue-Shu oral liquid (n=78) as treatment group, and routine clinical medicine (n=80) only served as the control group. The incidence of SBI and the classification of a favorable prognosis and a bad prognosis using the Glasgow outcome scale (GOS) were assessed to evaluate the clinical effects. The changes of IL-6 and TNF-α levels were determined to study the mechanism of the effects for the TCM. Results. The incidence of SBI at the end of week 2 was 8.97% in the treatment group and 23.75% in the control group, and the difference was significant (P<0.001). The incidence of a favorable prognosis was 48.72% in the treatment group and 32.72% in the control group, and the difference was significant (P<0.01) at the end of week 2. These findings indicate clear differences for IL-6 and TNF-α at the end of week 1 and week 2 compared with before treatment for the treatment group and a marked difference at the end of week 2 between the two groups. It also shows a significant difference between the end of week 2 and before treatment for IL-6 and TNF-α for the control group, although the difference was much smaller than the treatment group. Conclusion. Nao-Xue-Shu oral liquid could protect against the occurrence of SBI and improve HCH and SBI patients. It may also decrease the damage and the mass effects of the hematoma by reducing IL-6 and TNF-α to obtain the effects, and thus it is a potentially suitable drug for HCH and SBI

Nao-Xue-Shu Oral Liquid Improves Aphasia of Mixed Stroke

Objective. The objective is to observe whether the traditional Chinese medicine (TCM) Nao-Xue-Shu oral liquid improves aphasia of mixed stroke. Methods. A total of 102 patients with aphasia of mixed stroke were divided into two groups by a single blind random method. The patients treated by standard Western medicine plus Nao-Xue-Shu oral liquid ( = 58) were assigned to the treatment group while the remaining patients treated only by standard Western medicine ( = 58) constituted the control group. Changes in the Western Aphasia Battery (WAB), Modified Rankin Scale (mRS), National Institutes of Health Stroke Scale (NIHSS), and hemorheology parameters were assessed to evaluate the effects of the treatments. Results. Excluding the patients who dropped out, 54 patients in the treatment group and 51 patients in the control group were used to evaluate the effects. Significant and persistent improvements in the WAB score, specifically comprehension, repetition, naming, and calculating, were found in the treatment group when the effects were evaluated at the end of week 2 and week 4, respectively, compared with baseline. The naming and writing scores were also improved at the end of week 4 in this group. The comprehension and reading scores were improved at the end of week 4 in the control group compared with the baseline, but the improvements were smaller than those in the treatment group. The percentages of patients at the 0-1 range of mRS were increased at the end of week 2 and week 4 in both groups, but the improvements in the treatment group were much larger than those in the control group. Greater improvements in the NIHSS scores and the hemorheology parameters in the treatment group were also observed compared with the control group at the end of week 2 and week 4. Conclusion. Nao-Xue-Shu oral liquid formulation improved aphasia in mixed stroke patients and thus might be a potentially effective drug for treating stroke aphasia

The correlation timescale of the X-ray flux during the outbursts of soft X-ray transients

Recent studies of black hole and neutron star low mass X-ray binaries (LMXBs) show a positive correlation between the X-ray flux at which the low/hard(LH)-to-high/soft(HS) state transition occurs and the peak flux of the following HS state. By analyzing the data from the All Sky Monitor (ASM) onboard the Rossi X-ray Timing Explorer (RXTE), we show that the HS state flux after the source reaches its HS flux peak still correlates with the transition flux during soft X-ray transient (SXT) outbursts. By studying large outbursts or flares of GX 339-4, Aql X-1 and 4U 1705-44, we have found that the correlation holds up to 250, 40, and 50 d after the LH-to-HS state transition, respectively. These time scales correspond to the viscous time scale in a standard accretion disk around a stellar mass black hole or a neutron star at a radius of ~104-5 Rg, indicating that the mass accretion rates in the accretion flow either correlate over a large range of radii at a given time or correlate over a long period of time at a given radius. If the accretion geometry is a two-flow geometry composed of a sub-Keplerian inflow or outflow and a disk flow in the LH state, the disk flow with a radius up to ~105 Rg would have contributed to the nearly instantaneous non-thermal radiation directly or indirectly, and therefore affects the time when the state transition occurs.Comment: 7 pages, 3 figure

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals &lt;1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

5G NR downlink AOD-based localization

Large antenna arrays, millimeter-wave signals, large bandwidth and dense deployment are the characteristics of 5G networks. These technologies not only enable high-data rate communications but also have the potential superiority of accurate positioning. This dissertation aims to study the millimeter-wave positioning properties and existing angle of departure (AoD) based localization algorithms for 5G communication networks and integrate existing methods and add new contents to realize three-dimensional non-line-of-sight (NLOS) based localization with the assumption that received NLOS path signals only reflect once. To achieve the objective, the SAGE algorithm is applied to estimate channel parameters due to its faster convergence and lower complexity. The position of a mobile station (MS) is recovered using the estimated channel parameters through the geometrical relationship between base station (BS) and MS in three-dimensional scenario. The method can achieve sub-meter localization error with probability of 0.9 in NLOS scenario.Master of Science (Communications Engineering
