Amino Acids Hydrolyzed from Animal Carcasses Are a Good Additive for the Production of Bio-organic Fertilizer (2016)

High-quality bio-organic fertilizers (BIOs) cannot be produced without the addition of some proteins. In this study, compound liquid amino acids (CLAA) from animal carcasses were utilized as additives into matured composts to create novel BIOs containing plant growth-promoting rhizobacteria (PGPR). The results showed that adding CLAA and inoculating bacteria meanwhile resulted in failed solid-state fermentation (SSF) due to the higher H(+) contents. While after pre-compost for 4 days before PGPR inoculation, treatments of matured chicken or pig manure added with 0.2 ml g(-1) of CLAA resulted in a maximum biomass of functional strains. Illumine-MiSeq sequencing and Real-Time PCR results showed that the CLAA addition decreased the bacterial abundance and richness, altered the bacterial community structure and changed the relative abundance of some microbial groups. This study offers a high value-added utilization of waste protein resources for producing economical, high-quality BIO.
Categorization and Keyword Identification of Unlabeled Documents (2006)

In this paper, we first propose a global unsupervised feature selection approach for text, based on frequent itemset mining. As a result, each document is represented as a set of words that co-occur frequently in the given corpus of documents. We then introduce a locally adaptive clustering algorithm, designed to estimate (local) word relevance and, simultaneously, to group the documents. We present experimental results to demonstrate the feasibility of our approach. Furthermore, the analysis of the weights credited to terms provides evidence that the identified keywords can guide the process of label assignment to clusters. We take into consideration both spam email filtering and general classification datasets. Our analysis of the distribution of weights in the two cases provides insights on how the spam problem distinguishes from the general classification case.
Preoccupations and intentions (1968)

It has been suggested that I should write of my preoccupations and the intentions of my books, which are their result. After nearly seventy-five years of life it is hard to state accurately what these have been, as they have changed their predominance at different periods.
TURBULENT FLOW CHARACTERISTICS OF CHANNEL FLOW USING LARGE EDDY SIMULATION WITH WALL-FUNCTION(FDS CODE) (2015)

The turbulent flow characteristics in the channel flow are investigated using large eddy simulation(LES) of FDS code, built in NIST(USA), in which the near-wall flow is solved by Werner-Wengle wall function. The periodic flow condition is applied in streamwise direction to get the fully developed turbulent flow and symmetric condition is applied in lateral direction. The height of the channel is H=1m, and the length of the channel is 6H, and the lateral length is H. The total grid is <TEX>$32{\times}32{\times}32$</TEX> and <TEX>$y^+$</TEX> is kept above 11 to fulfill the near-wall flow requirement. The Smagorinsky model is used to solve the sub-grid scale stress. Smagorinsky constant <TEX>$C_s$</TEX> is 0.2(default in FDS). Three cases of Reynolds number(10,700, 26,000, 49,000.), based on the channel height, are analyzed. The simulated results are compared with direct numerical simulation(DNS) and particle image velocimetry(PIV) experimental data. The linear low-Re eddy viscosity model of Launder & Sharma and non-linear low-Re eddy viscosity model of Abe-Jang-Leschziner are utilized to compare the results with LES of FDS. Reynolds normal stresses, Reynolds shear stresses, turbulent kinetic energys and mean velocity flows are well compared with DNS and PIV data.
Analysis of conjugated steroid androgens: Deconjugation, derivatisation and associated issues (2009)

Gas chromatography/mass spectrometry (GC/MS) is the preferred technique for the detection of urinary steroid androgens for drug testing in athletics. Excreted in either the glucuronide or sulfated conjugated form, steroids must first undergo deconjugation followed by derivatisation to render them suitable for GC analysis. Discussed herein are the deconjugation and the derivatisation preparative options. The analytical challenges surrounding these preparatory approaches, in particular the inability to cleave the sulfate moiety have led to a focus on testing protocols that reply on glucuronide conjugates. Other approaches which alleviate the need for deconjugation and derivatisation are also highlighted.
Effectiveness of training in expressing positive emotions, reacting to change and greeting peers after childhood traumatic brain injury: a single-case experimental study (2023)

While the participant showed improvements in all three targeted behaviors, due to the complexity of the third behavior, it is recommended that in future research, the intervention targeting social interactions should be applied over a longer timeframe to ensure that improvements are more stable in the long term.
GLYCOSYLATED HEMOGLOBIN IN A POPULATION-BASED STUDY OF DIABETES (1987)

Glycosylated hemoglobin was measured in persons who participated in a population-based study of diabetic retinopathy in southern Wisconsin. There were 996 persons who were diagnosed prior to 30 years of age and who were taking insulin (younger onset), and 1,370 persons who were diagnosed at 30 years of age or older (older onset) who were examined from 1980-1982. Glycosylated hemoglobin was measured using a microcolumn technique. Mean glycosylated hemoglobin was highest in younger onset persons (10.9%), and lowest in older onset persons not taking insulin (9.0%). Only a small percentage of values for the diabetic persons fell within the range of values found in a nondiabetic comparison group. Mean glycosylated hemoglobin was found to be associated with retinopathy status but not with proteinuria.
Research on fast Fourier transforms algorithm of huge remote sensing image technology with GPU and partitioning technology. (2014)

Fast Fourier transforms (FFT) is a basic approach to remote sensing image processing. With the improvement of capacity of remote sensing image capture with the features of hyperspectrum, high spatial resolution and high temporal resolution, how to use FFT technology to efficiently process huge remote sensing image becomes the critical step and research hot spot of current image processing technology. FFT algorithm, one of the basic algorithms of image processing, can be used for stripe noise removal, image compression, image registration, etc. in processing remote sensing image. CUFFT function library is the FFT algorithm library based on CPU and FFTW. FFTW is a FFT algorithm developed based on CPU in PC platform, and is currently the fastest CPU based FFT algorithm function library. However there is a common problem that once the available memory or memory is less than the capacity of image, there will be out of memory or memory overflow when using the above two methods to realize image FFT arithmetic. To address this problem, a CPU and partitioning technology based Huge Remote Fast Fourier Transform (HRFFT) algorithm is proposed in this paper. By improving the FFT algorithm in CUFFT function library, the problem of out of memory and memory overflow is solved. Moreover, this method is proved rational by experiment combined with the CCD image of HJ-1A satellite. When applied to practical image processing, it improves effect of the image processing, speeds up the processing, which saves the time of computation and achieves sound result.
342 Real-time Measurement of Dynamic Stiffness on the Body Surface Using Self-Excited Vibration Generated by Positive Feedback of the Velocity : Improvement of Response and Accuracy by the Kalman Filter (2008)

The method for real time measurement of the dynamic stiffness in subcutaneous tissues was developed by the authors. The dynamic stiffness is estimated by using the self-excited vibration generated by the positive feedback of velocity. In this report, we show the response and the accuracy of frequency estimation are improved by using Kalman filter as an adaptive filter. And the internal damping of the apparatus measurement is reduced. As a result, the time-varying dynamic stiffness on human body by muscular contraction can be measured rapidly and stability. And the dynamic stiffness on parts of the human body are measured, their characteristics are compared.
The control strategy of optimal brake energy recovery for a parallel hydraulic hybrid vehicle (2012)

The purpose of this paper is to develop a control strategy of optimal brake energy recovery for a parallel hydraulic hybrid vehicle, in which the shifting schedule of the torque coupler and the distribution of the braking force are the most important impact factors based on a detailed study of braking characteristics. The two implementable schemes are compared to achieve a better shifting schedule for the torque coupler. An optimal distributive curve and the corresponding models of braking forces are also established, which not only avoids the situation of rear wheels locking earlier than front wheels but also determines the distributive ratio of the braking forces in each case. The simulation models of the vehicle are developed on the basis of the software, Advisor 2002, which is validated by the road tests. The simulation results indicate that 42.7% of the brake energy can be recaptured in the hydraulic hybrid vehicle, whereas 41.6% of the traction energy is wasted in the braking of a conventional vehicle. Therefore, the control strategy of optimal energy recovery is very effective in improving the efficiency of brake energy recovery in the hydraulic hybrid vehicle.
Anticancer potency of small linear and cyclic tetrapeptides and pharmacokinetic investigations of peptide binding to human serum albumin (2014)

We have in the present study explored the anticancer activity against human Burkitt's lymphoma cells (Ramos) of a series of small linear and cyclic tetrapeptides containing a β2,2-amino acid with either two 2-naphthyl-methylene or two para-CF3-benzyl side chains, along with their interaction with the main plasma protein human serum albumin (HSA). The cyclic and more amphipathic tetrapeptides revealed a notably higher anticancer potency against Ramos cells [50% inhibitory concentration (IC50) 11–70 μM] compared to the linear tetrapeptide counterparts (IC50 18.7 to >413 μM). The most potent cyclic tetrapeptide c3 had a 16.5-fold preference for Ramos cells compared to human red blood cells, whereas the cyclic tetrapeptide c1 both showed low hemolytic activity and displayed the overall highest (2.9-fold) preference for Ramos cells (IC50 23 μM) compared to healthy human lung fibroblast cells (MRC-5). Investigating the interaction of selected tetrapeptides and recently reported hexapeptides with HSA revealed that the peptides bind to drug site II of HSA in the 22–28 μM range, disregarding size and overall structure. NMR and in silico molecular docking experiments identified the lipophilic residues as responsible for the interaction, but in vitro studies showed that the anticancer potency of the peptides varied in the presence of HSA and that c3 remained the most potent peptide. Based on our findings, we call for implementing serum albumin binding in development of anticancer peptides, as it may have implications for future administration and systemic distribution of peptide-based cancer drugs.
Silicone based membranes for organic solvent nanofiltration (2015)

One of the polymers enabling successful application of organic solvent nanofiltration membranes is silicone or more precisely poly(organosiloxane). This thesis includes a study on silicone based membranes, as to their chemistry, their separation performance in organic solvents and influence of introduced functional groups. The performance of a silicone based membrane was first compared to membranes based on polyimide and PIM-1 (polymers of intrinsic microporosity). The tests were made in heptane and acetone to underlie the difference in the separation properties of the tested membrane materials. Further, the development of a predictive model for multicomponent mass transport through a silicone membrane was made. The applied modelling approach can be differentiated in a Flory-Rehner based model to estimate membrane swelling and a simplified Maxwell-Stefan mass transport model. The prediction accuracy of developed modelling approach was compared to the measured values for eleven pure solvents. The predicted values of styrene oligomer rejection curves in these solvents were also compared to the measured values. The production and performance of composite membranes made from acrylatefunctional and epoxy-functional silicones in styrene oligomer/heptane mixture were also investigated. Next to this, a performance comparison in several solvents of acrylate-functional, epoxy-functional and a commercially available silicone based membrane was made. The measured results were used together with modelling approach to determine membrane specific parameters and their relevance in accurate predicting of the measured data.
Effects of grass on induced soil suction during Evapotranspiration and ponding (2020)

Soil suction induced by grass Evapotranspiration (ET) in vegetated landfill covers is recognised to potentially reduce percolation (due to the decrease in water permeability) and also improve slope stability (due to the increase in soil shear strength) upon rainfall. However, grass-induced suction is generally ignored when analysing a vegetated cover because effects of root-water uptake on suction is less understood. In this study, a series of laboratory tests were conducted to measure suction induced during ET and suction retained during ponding. Compacted silty sand with and without vegetated with a grass species, Cynodon dactylon, were tested in an atmospheric-controlled room. Responses of suction were monitored by 12 tensiometers. By investigating water flow mechanism in vegetated soil, vertical and horizontal influence zones of suction are identified in relation to grass root characteristics. Measurements from bare and vegetated soil are compared to quantify the effects of grass on suction retention upon ponding.
Gold Nanocluster-DNase 1 Hybrid Materials for DNA Contamination Sensing (2014)

Protein encapsulated gold nanocluster (P-AuNC) synthesis was first demonstrated in 2009.[1]Initially these P-AuNCs were used as cellular imaging agents as the protein shell surrounding the AuNC made them highly biocompatible.However, recent studies have begun to show that these stabilizing proteins may also retain native biological function thus giving a dual functionality to these hybrid molecules.Here we present the synthesis of DNase 1 stabilized gold nanoclusters (DNase 1:AuNCs) with core sizes consisting either 8 or 25 atoms.The DNase 1:Au 8 NCs exhibit blue fluorescence whereas the DNase 1:Au 25 NCs are red emitting.Moreover, in addition to the intense fluorescence emission; the synthesized DNase 1:AuNC hybrid retain the native functionality of the protein, allowing simultaneous detection and digestion of DNA with a detection limit of 2 g/mL (Scheme 1).The DNase 1:AuNCs could be conveniently employed as efficient and fast sensors to augment the current inefficient and time consuming DNA contamination analysis techniques.I.
5‐(Cyano)dibenzothiophenium Triflate: A Sulfur‐Based Reagent for Electrophilic Cyanation and Cyanocyclizations (2019)

The synthesis of 5-(cyano)dibenzothiophenium triflate 9, prepared by activation of dibenzo[b,d]thiophene-5-oxide with Tf<sub>2</sub> O and subsequent reaction with TMSCN is reported, and its reactivity as electrophilic cyanation reagent evaluated. The scalable preparation, easy handling and broad substrate scope of the electrophilic cyanation promoted by 9, which includes amines, thiols, silyl enol ethers, alkenes, electron rich (hetero)arenes and polyaromatic hydrocarbons, illustrate the synthetic potential of this reagent. Importantly, Lewis acid activation of the reagent is not required for the transfer process. We additionally report herein biomimetic cyanocyclization cascade reactions, which are not promoted by typical electrophilic cyanation reagents, demonstrating the superior ability of 9 to trigger challenging transformations.
Albania - urban and rural water and sanitation reforms (2004)

Albania is one of the poorest countries in Europe. Even today, 40 percent of Albanian households lack basic education, heat, and sanitation; fewer than 50 percent in both rural and urban areas have access to safe and clean drinking water. Yet Albania is blessed with an abundant supply of water resources. Precipitation throughout the country is high. Groundwater is plentiful and of excellent quality, requiring little or no treatment beyond for chlorination. Except in Tirana, where about half of the water supply is treated surface water, the country relies entirely on groundwater for drinking. Over the last decade Albania has dramatically improved its dilapidated water supply, irrigation, and sanitation facilities through an approach that focuses on the empowerment of local governments; involvement of the private sector in delivering urban services; and use of community-centered approaches for sustainable rural services. The World Bank initiated long-term support for Albania's water projects in 1994. The challenges were to reform, repair, and rebuild the water supply sector; to extend access to good water to the poor in urban and rural areas; and to begin to treat wastewater and sewage. Preliminary results show steady progress.
Safety Analysis of Software-intensive Motion Control Systems (2009)

&lt;div class="htmlview paragraph"&gt;The auto industry has had decades of experience with designing safe vehicles. The introduction of highly integrated features brings new challenges that require innovative adaptations of existing safety methodologies and perhaps even some completely new concepts.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;In this paper, we describe some of the new challenges that will be faced by all OEMs and suppliers. We also describe a set of generic top-level potential hazards that can be used as a starting point for the Preliminary Hazard Analysis (PHA) of a vehicle software-intensive motion control system. Based on our experience with the safety analysis of a system of this kind, we describe some general categories of hazard causes that are considered for software-intensive systems and can be used systematically in developing the PHA.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;A comprehensive PHA for a software-intensive motion control system may reveal potential interactions of features that are not due to malfunctions of the features’ individual components but that may lead to hazardous conditions. This insight and other lessons learned from our experience with such systems have influenced the drafting of ISO CD 26262.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Finally, this paper reports on our preliminary experience with the method of risk assessment proposed for ISO CD 26262 Part 3, Concept Phase.&lt;/div&gt;
Secure Authentication Protocol Based on Machine-metrics and RC4-EA Hashing (2016)

Most authentication schemes are using physical token such as smart cards to restrict services. Although these schemes have been widely deployed for various kinds of daily applications; there are severe challenges regarding their infrastructure requirements and security. This paper proposes an efficient authentication protocol based on user's machine-metrics. The proposed protocol uses the machine physical metrics to identify machines in the network, which provides the basic capability to prevent an unauthorized machine to access resources. Thus, machine-merics based authentication for machine can be looked as an analog of biometric-based authentication for human. The proposed protocol is employing the RC4-EA Hashing function to secure the collected machine-merics. Since it is satisfying the basic requirements of a cryptographic hash function. Therefore, the purpose of the proposed protocol is theft-proofing and guarding against attacks based on stolen or lost tokens. Also, it offers strong protection against several attacks such as credential compromising attacks.
Senescence of alveolar epithelial progenitor cells: a critical driver of lung fibrosis (2023)

Pulmonary fibrosis comprises a range of chronic interstitial lung diseases (ILDs) that impose a significant burden on patients and public health. Among these, idiopathic pulmonary fibrosis (IPF), a disease of aging, is the most common and most severe form of ILD and is treated largely by lung transplantation. The lack of effective treatments to stop or reverse lung fibrosis-in fact, fibrosis in most organs-has sparked the need to understand causative mechanisms with the goal of identifying critical points for potential therapeutic intervention. Findings from many groups have indicated that repeated injury to the alveolar epithelium-where gas exchange occurs-leads to stem cell exhaustion and impaired alveolar repair that, in turn, triggers the onset and progression of fibrosis. Cellular senescence of alveolar epithelial progenitors is a critical cause of stemness failure. Hence, senescence impairs repair and thus contributes significantly to fibrosis. In this review, we discuss recent evidence indicating that senescence of epithelial progenitor cells impairs alveolar homeostasis and repair creating a profibrotic environment. Moreover, we discuss the impact of senescent alveolar epithelial progenitors, alveolar type 2 (AT2) cells, and AT2-derived transitional epithelial cells in fibrosis. Emerging evidence indicates that transitional epithelial cells are prone to senescence and, hence, are a new player involved in senescence-associated lung fibrosis. Understanding the complex interplay of cell types and cellular regulatory factors contributing to alveolar epithelial progenitor senescence will be crucial to developing targeted therapies to mitigate their downstream profibrotic sequelae and to promote normal alveolar repair.<b>NEW & NOTEWORTHY</b> With an aging population, lung fibrotic diseases are becoming a global health burden. Dysfunctional repair of the alveolar epithelium is a key causative process that initiates lung fibrosis. Normal alveolar regeneration relies on functional progenitor cells; however, the senescence of these cells, which increases with age, hinders their ability to contribute to repair. Here, we discuss studies on the control and consequence of progenitor cell senescence in fibrosis and opportunities for research.
