Matrix and Tensor Completion in Multiway Delay Embedded Space Using Tensor Train, With Application to Signal Reconstruction

In this paper, the problem of time series reconstruction in a multiway delay embedded space using Tensor Train decomposition is addressed. A new algorithm has been developed in which an incomplete signal is first transformed to a Hankel matrix and in the next step to a higher order tensor using extended Multiway Delay embedded Transform. Then, the resulting higher order tensor is completed using low rank Tensor Train decomposition. Comparing to previous Hankelization approaches, in the proposed approach, blocks of elements are used for Hankelization instead of individual elements, which results in producing a higher order tensor. Simulation results confirm the effectiveness and high performance of the proposed completion approach. Although in this paper we focus on single time series, our method can be straightforwardly extended to reconstruction of multivariate time series, color images and videos.
Patient loyalty to health services: The role of communication skills and cognitive trust

ABSTRACT This study holistically examined the effects of healthcare providers’ or physicians’ communication skills on their patients’ continuous usage intention, which may influence the perception of a patient's cognitive trust. A total of 1,300 questionnaires were distributed, of which 253 valid response samples were analyzed. The results showed that a physician's communication skills had a positive effect on a patient's cognitive trust. Furthermore, the patient's cognitive trust was found to have a positive effect on continuous usage intention. This suggests that patients can develop cognitive trust and that the doctor-patient relationship can be consequently maintained, if the doctors listen to their patients and perceive their implicit thoughts and feelings from their behaviors.
ANTIOXIDANT ACTIVITIES OF ENZYMATIC EXTRACTS FROM AN EDIBLE SEAWEED SARGASSUM HORNERI USING ESR SPECTROMETRY

The antioxidant activity of water-soluble natural extracts from an edible seaweed, Sargassum horneri, was evaluated by examining the radical scavenging activities of the extracts of hydrolyzates from S. horneri on 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl and alkyl radicals. A spin-trapping electron spin resonance (ESR) spectrophotometer was employed and the results were compared for their ESR signal intensity. The brown seaweed S. horneri was enzymatically hydrolyzed to prepare water-soluble extracts by five carbohydrases (AMG, Celluclast, Termamyl, Ultraflo and Viscozyme) and five proteases (Alcalase, Flavourzyme, Kojizyme, Neutrase, Protamex). The extracts so prepared exhibited strong scavenging activity on DPPH, hydroxyl and alkyl radicals. The scavenging activity of the radicals increased with increased concentration of the extracts. The scavenging results were higher or similar for hydroxyl and alkyl radicals, and lower for DPPH radical compared with vitamin C as a reference. Viscozyme and Alcalase extracts were superior and scavenged radicals examined better than the extracts prepared by other carbohydrases and proteases.
Environmental impact of seasonal integrated aquaculture ponds ('fingerponds') in the wetlands of Lake Victoria, Kenya: an assessment, with the aid of Bayesian Networks

The potential effect on ecosystem integrity of the use of natural wetlands for seasonal wetland fishponds ('fingerponds'), integrated with vegetable production for livelihood demands, was evaluated using experimental sites at Lake Victoria, Kenya. Soluble reactive phosphorous and total phosphorus, ammonium, nitrate and total nitrogen data showed no evidence of nutrients leaching from the ponds into the immediate wetland groundwater. Nutrient concentrations in pond water were significantly higher than those in the groundwater in the immediate wetland environment. Bayesian Networks were used to evaluate the main environmental concerns. The environmental impact of fingerponds, particularly on hydrology and biodiversity, was low, although land-use changes at the immediate site where the ponds were dug had direct impacts. Whereas this study was based on short-term monitoring of experimental fingerponds, scaling up of these systems may increase their impact. Continued monitoring is needed during the scaling-up phase.
Finite‐time tracking control for a class of nonlinear systems with multiple mismatched disturbances

This article investigates the finite‐time output tracking problem for a class of nonlinear systems with multiple mismatched disturbances. To efficiently estimate the disturbances and their derivatives, a continuous finite‐time disturbance observer (CFTDO) design method is developed. Based on the modified adding a power integrator method and CFTDO technique, a composite tracking controller is constructed such that the system output can track the desired reference signal in finite time. Simulation results demonstrate the effectiveness of the proposed control approach.
Dissolution profile of partially purified bromelain from pineapple core encapsulated in alginate-guar gum with in vitro study of antiplatelet activity

The aim of this study is to maintain the antiplatelet activity of pineapple core bromelain from degradation in gastric fluid by encapsulating the enzyme in alginate-guar gum crosslinked with glutaraldehyde. Bromelain isolation was followed by purification process such as ammonium sulfate precipitation and dialysis. The specific activity obtained showed an enhancement started for crude enzyme (20.11 U/mg), ammonium sulfate fraction (190.64 U/mg), and dialysis fraction (229.77 U/mg). Dialysis fraction was encapsulated by in situ loading method in alginate-guar gum hydrogel with 1.25% (v/v) glutaraldehyde concentration. The swelling ratio of the hydrogel is 234.37 % in acidity of 1.2; and 1375.91 % in acidity of 7.4; while the encapsulation efficiency amount was 60.42%. I n addition, maximum concentration of bromelain released in dissolution test was higher in artificial intestinal environment (1.79 mg/L) than in artificial gastric fluid (0.13 mg/L), with maximum proteolytic activity of 1.2 U/mL and 0.11 U/mL, respectively. In vitro study of antiplatelet activity showed a good inhibition for dialysis fraction (50.6 %) and dissolution fraction (34.86 %), indicating that the hydrogel is good enough to maintain the activity of bromelain.
Pododermatite de contato em frangos de corte

Occurrence of contact pododermatitis in broilers in the State of Minas Gerais, Brazil, is reported. Lesions in the footpad were detected as early as 13 days of age and progressed to ulceration. Histologically, primarily inflammatory and degenerative changes mostly at the epidermal-dermal junction were observed. Retrospective evaluation indicated that pododermatitis in these cases were associated with exposure to high litter moisture during the first days of life.
Molluscan Hard-Substrate Associations in the Northern Red Sea

The mollusc associations of 29 hard-substrate localities in the Northern Bay of Safaga Red Sea, Egypt were studied. The hard substrates were classified into 7 types: reef flats, intertidal rock bottom, very shallow subtidal conglomerate, Porites carpet, faviid carpet, platy scleractinian association, Sarcophyton carpet. Based on a cluster analysis the molluscs of these hard substrates can be classified into 5 groups: Group A is dominated by Dendropoma maxima, Chamoidea and Tridacna maxima, group B by Pedum spondyloideum, T. maxima and Coralliophila neritoidea, group C by Chamoidea and Cerithium ruppelli, group D by Modiolus auriculatus, Chamoidea, Morula granulata and Nerita albicilla and group E by Chamoidea and Pitar hebraea. The latter group contains only samples which are generally poor in molluscs. Group A molluscs are diagnostic for reef flats, group B for Porites and faviid carpets, group C for Sarcophyton carpets and group D for tidal/shallow subtidal rock substrates. The different hard substrates are therefore characterized by diagnostic mollusc associations and some of them could also be identified in the fossil record.
Utilization of the Business Process Maturity Model as a Proposed Architectural Planning of Business Model Concept

This research is a part of previous research which succeeded in producing business model architecture planning, the purpose of this research is to develop previous research using business model maturity measurement methods as a proposed business model architecture planning concept. By taking the same case study theme as Tiara Payung Putra (TPP) company. TPP is known as a distributor company in cooperation with Pertamina's (Bulk LPG Filling and Filling Station). TPP's main business activity is to distribute goods in the form of LPG to 76 bases spread across the Balaraja district. The current condition of the business model architecture illustrates the business activities that exist in the TPP. The main problems that occur in the TPP are not integrated the external system with internal business activities in the company, and the lack of IT resource support. For this reason, the Business Process Maturity Model is needed as a benchmark, which can be proposed as a business architecture planning concept. Support for the Enterprise Architecture Planning (EAP) Framework method focuses on the business model architecture domain. The architecture of the business model illustrates how TPP carries out business activities and functions to achieve its objectives. The results of this study produce proposed business model architecture planning concepts in the form of Business Model Maturity Level Measurement, SI / IT architecture concepts, and Business Architecture Planning roadmap, which are beneficial for Tiara Payung Putra (TPP) company for business model architecture planning.
Challenges of Measuring Abyssal Temperature and Salinity at the Kuroshio Extension Observatory

The deep ocean is severely undersampled. Whereas shipboard measurements provide irregular spatial and temporal records, moored records establish deep ocean high-resolution time series, but only at limited locations. Here, highlights and challenges of measuring abyssal temperature and salinity on the Kuroshio Extension Observatory (KEO) mooring (32.3°N, 144.6°E) from 2013 to 2019 are described. Using alternating SeaBird 37-SMP instruments on annual deployments, an apparent fresh drift of 0.03–0.06 psu was observed, with each newly deployed sensor returning to historical norms near 34.685 psu. Recurrent salinity discontinuities were pronounced between the termination of each deployment and the initiation of the next, yet consistent pre- and postdeployment calibrations suggested the freshening was “real. ” Because abyssal salinities do not vary by 0.03–0.06 psu between deployment locations, the contradictory salinities during mooring overlap pointed toward a sensor issue that self-corrects prior to postcalibration. A persistent nepheloid layer, unique to KEO and characterized by murky, sediment-filled water, is likely responsible for sediment accretion in the conductivity cell. As sediment (or biofouling) increasingly clogs the instrument, salinity drifts toward a fresh bias. During ascent, the cell is flushed, clearing the clogged instrument. In contrast to salinity, deep ocean temperatures appear to increase from 2013 to 2017 by 0.0059°C, whereas a comparison with historical deep temperature measurements does not support a secular temperature increase in the region. It is suggested that decadal or interannual variability associated with the Kuroshio Extension may have an imprint on deep temperatures. Recommendations are discussed for future abyssal temperature and salinity measurements.

Institutionalization of Community-based Sustainable Development Governance in Government of Central Java Province

In National Medium-Term Development Plan of Indonesia 2005-2025, sustainable development is used as a mainstreaming of national development. As the main stream of national development, it means that every aspect of development needs to apply the principle of sustainable development, namely efficiency in the use of resources and attention to the impact on the community's environment. Sustainable development is a principle of development that applies in the long run. What distinguishes it from year to year is its application in a concrete and gradual manner. The keyword in seeing the implementation of sustainable development as the main stream of development is a concrete and gradual application. Concrete because that is what is the expectation of the community, gradually because the level of community readiness needs to be considered, as well as the level of readiness of the instrument to implement it. Phasing is also needed in order to be able to focus and measure the progress of the results of implementing sustainable development. Central Java is an attractive locus, because the Provincial Government of Central Java is considered as one of the most advanced local governments in implementing sustainable development programs. So, in Dye's view, all policies will ultimately lead to the same thing, namely the description and explanation of the causes and consequences of government action. For this reason, institutional governance and policy capacity in Central Java are needed for the implementation of community-based sustainable development, thus the institutional framework and policy capacity are not solely the wishes of the government, but also the desires and demands of the needs of the community.
VOCALIZATIONS AROUND THE TIME OF MILK EJECTION IN DOMESTIC PIGLETS: A RELIABLE INDICATOR OF THEIR CONDITION?

In some nursings, piglets initiate nose contacts with their mother and emit typical 'croaking' vocalizations. We examined whether the croaking vocalizations reflect the condition of the piglets and whether the sows increase their maternal investments in response to those vocalizations. The following predictions were tested: (i) Piglets with lower weight gain should vocalize more than piglets with higher weight gain; (ii) piglets' milk intake is lower in those nursings in which they vocalize after milk ejection; (iii) piglets make more croaking vocalization in nursings which were preceded by longer intervals since the last nursing with milk ejection; (iv) sows permit longer post-ejection massage in nursings in which piglets vocalized immediately after milk ejection; (v) sows decrease the interval until the succeeding nursing after those nursings in which the piglets have vocalized. Hypotheses (i) and (ii) were investigated by controlling the inter-nursing intervals in 14 sows and recording the milk intake of individual piglets' over 24 hours during days 7 or 8 post partum (Experiment 1). Hypotheses (iii) to (v) were examined through analysing video recordings of undisturbed six h nursing sequences in 29 sows (Experiments 2 and 3). The majority of our predictions were not confirmed: piglets did not vocalize more (either before or after milk ejection) after longer intervals since last milk ejection; they did not vocalize more in nursing in which they received less milk; and it was not the piglets or the litter with a lower milk intake or lower weightgain that emitted more vocalization. Neither of our predictions regarding the influence of croaking vocalizations on maternal investment was confirmed. The vocalizations were in no way associated with the length of the following inter-nursing interval or with the permission of longer udder massage. To conclude, piglet croaking vocalizations during nursings are not reliable indicators of piglet condition and are not used by sows to adjust their maternal investment.
Development of an Enhanced Congestion Control Protocol in Transmission Control Protocol

The common problems that motivate most of the researchers in the field of congestion control revolves around how to have a congestion free network while maintaining efficient links utilization, fairness, elimination of packet loss/drop as well as achieving throughput in an heterogeneous network environments. This work adopted internet prey-predator model protocol and enhanced it. The network topology consist of a router, an access point (AP), four wired and wireless nodes were used as test bed. Network Simulator 3 (ns-3) and C++ was used to simulate the work. The work examined the basis of congestion variant and develop a new enhanced congestion control protocol. The numerical results obtained under different simulation scenarios show that the new protocol manifest high bandwidth utilization, reduced loss rate, fairness among the flows and improved throughput. The new protocol is recommended to be deployed on the public transmission control protocol stack, this will not only improve the network performance but also better subscribers experience and give them value for their money. It will also afford the Internet Service Providers the opportunity to provide uninterruptible internet access. Future work can focus on improving the performance of TCP with chaotic control theory using machine learning to better explore the model.

Alfalfa Root Nitrogen Reserves and Regrowth Potential in Response to Fall Harvests

The adverse effect of fall harvesting alfalfa (Medicago saliva L.) during a critical rest period on persistence and the following spring regrowth has been historically attributed to a reduction in the concentrations of organic reserves, especially total nonstrudural carbohydrates. However, recent reports highlight the determinant role of N reserves in overwintering and spring regrowth of alfalfa. This study was undertaken to assess the impact of fall harvest management on regrowth potential in relation to the quantitative changes in N reserves in alfalfa taproots throughout fall and winter. The experiment was conducted under simulated winter conditions in an unheated greenhouse with two alfalfa cultivars (AC Caribou and WL 225). The fall harvest treatments were no additional fall harvest (two harvests = control) or a third fall harvest applied at 400, 500, or 600 growing degree days (GDD) after the second harvest. Total N concentrations were significantly reduced in plants harvested at 400 or 500 GDD as compared with plants harvested at 600 GDD or harvested only twice. The striking accumulation of proline, arginine, and histidine observed in fall and winter was depressed by a fall harvest, especially in plants harvested at 400 or 500 GDD. The abundance of a major soluble protein of 32 kDa was reduced by harvesting at 400 or 500 GDD. Concentrations of major N components were correlated with shoot regrowth in spring in AC Caribou, but not in WL 225. However, the total amounts of major N components in taproots were correlated with spring regrowth In both cultivars. Our results point out that N reserves available in roots are determinant for spring regrowth in alfalfa under various fall harvest treatments.
Macrolichens of the Pacific Northwest

Lichens can be found in almost any natural habitat in the Pacific Northwest. In addition to contributing to biological diversity, lichens are ecologically important as food, shelter, and nesting material for wildlife. They play significant roles in hydrological and mineral cycles, notably nitrogen fixation. Lichens are also important as environmental indicators, especially of air quality. Because of their importance in ecosystems and their value in environmental assessment, there is a large and growing interest among natural historians, land managers, and foresters in these organisms.
A HIGHLY EFFICIENT AND HIGHLY RELIABLE PROTOCOL FOR TRANSFORMATION OF ESCHERICHIA COLI BY ELECTROPORATION

Electroporation is widely adopted for highly efficient transformation of Escherichia coli of different purposes, but its efficiency is highly varied in the range of several orders of magnitude. Here we describe a modified and highly reliable electroporation protocol which combines low temperature growth in the presence of sucrose with a postelectroporation heat pulse, which not only gives rise to an over 250-fold enhancement in transformation compared with conventional protocols, but also alleviates the need for a strict low temperature control at all times of an electroporation-competent cell preparation experiment and highly pure MilliQ grade water which is not readily available in many laboratories. Transformations for a 6-kb E. coli and yeast shuttle vector were always higher than 107 transformants/µg, and more than 108 transformants/µg were sometimes recorded in routine experiments. PRACTICAL APPLICATIONS Transformation efficiency reached up to 8 × 109 transformants/µg DNA with ElectroMAXTM DH10BTMEscherichia coli cells and a 6-kb pYES2/CT plasmid using our procedure, when combined with reduction of ampicillin concentration from 100 µg/mL to 20 µg/mL in the selection plates. It is highly efficient and highly reliable on DNA library construction of all kinds, especially from minute cell and tissue samples, under routine laboratory conditions. It will find widespread application in molecular manipulations in Escherichia coli, the workhorse of molecular biology.
Laboratory diagnostic methods and reported outbreaks of anthrax in Ethiopia

Anthrax is a zoonotic disease caused by Bacillus anthracis, a Gram-positive, non-motile, spore-forming bacterium. It is a globally distributed disease, having been reported from all continents that are populated heavily with animals and humans. The objectives were to review general laboratory diagnostic testing methods and reported outbreaks of anthrax in Ethiopia. Anthrax was second top zoonotic priority next to rabies and endemic in Ethiopia that may occur in May and June every year (Anthrax season) in several farming localities. Animal hosts acquire the disease through grazing, usually by ingestion or inhalation while there are three major routs of transmission: ingestion, inhalation and cutaneous. This review indicated that anthrax remains to be major public and animal health problem in Ethiopia. Although suspected cases of anthrax are reported from several districts, they are not well confirmed by laboratories. Prevention and control of anthrax in animals effectively reduces its impact on public health and the national economy. The control of anthrax outbreaks among domestic animals is primarily dependent on rapid identification and treatment of affected animals; enhanced surveillance for additional cases; implementation of control measures including quarantine, prophylaxis, vaccination and the proper disposal of dead animals with decontamination is critical.
