The importance of model fidelity, update rate and horizon length in model based microgrid control

Field: Energy (Physical Sciences)

In order to maximize the effectiveness of microgrids sophisticated control strategies are required. In this paper we investigate the performance of a model based power flow optimization controller for a grid connected microgrid consisting of; solar PV, battery storage, thermal generation, and a local electrical load. The controller is based on a mixed integer linear program (MILP) applied in a model predictive control framework (MPC). In the MPC problem formulation there are two design parameters that need to be considered, the update rate of the controller and the number of steps considered in the on-line optimisation problem. Previous work by the authors has demonstrated that the former is critical in order to respond to the high variability associated with solar generation. In this work we extend the previous study to highlight the effect of update rate on battery utilization and the consequential effect on cumulative system operating cost. We demonstrate that the number of steps in the controller horizon has a largely inconsequential impact due to the battery being primarily utilised to ensure efficient generator operation as opposed to providing long term energy storage. Furthermore, the importance of model fidelity is investigated and a 42% decrease in operating cost over a 1 month period is observed when generator fuel consumption non-linearities are incorporated in the controller design, as opposed to a constant efficiency fuel consumption model.
A Low-Power Digitizer for Back-Illuminated 3-D-Stacked CMOS Image Sensor Readout With Passing Window and Double Auto-Zeroing Techniques

Field: Engineering (Physical Sciences)

This paper presents a high-performance digitizer based on column-parallel single-slope analog-to-digital converter (SS-ADC) topology for readout of a back-illuminated 3-D-stacked CMOS image sensor. To address the high power consumption issue in high speed digital counters, a passing window (PW)-based hybrid counter topology is proposed. In this approach, the memory cells in the digital counters of SS-ADCs are disconnected from the global bus during non-relevant timing. To address the high column fixed pattern noise (FPN) under bright illumination conditions, a double auto-zeroing (AZ) scheme is proposed. In this technique, the AZ process is employed twice at reset and signal level, respectively. The double AZ scheme not only allows the comparator to serve as a crossing detector around the common-mode level, but it also enables low-voltage comparator design. The proposed techniques are experimentally verified in a prototype chip designed and fabricated in the TSMC 40 nm low-power CMOS process. The PW technique saves 52.8% of power consumption in the hybrid digital counters. Dark/bright column FPN of 0.0024%/0.028% is achieved employing the proposed double AZ technique for digital correlated double sampling. A single-column digitizer consumes a total power of 66.8 μW and occupies an area of 5.4 μm × 610 μm.

<b>Performance in preweaning pure and crossbred calves in the Mato Grosso do Sul Pantanal region, Aquidauana, Mato Grosso do Sul State, Brazil

Field: Agricultural and Biological Sciences (Life Sciences)

Purebred and crossbred calves (n = 3,871) were selected that were born in the sub-region of the Pantanal of Aquidauana (Brazil), derived from Nellore, Brangus, Wagyu, and ½ Brangus + ½ Nellore cows, which were artificially inseminated by bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyubreeds. Parameters such as weaning weight, daily gain from birth to weaning, and the number of days to gain 160 kg, were assessed inthese calves and phenotypic correlations between the traits were evaluated. Data were analyzed using two statistical models. The first model included sire breed effects, the genetic group of the cow, sex, year of birth (AN), birth season (EN), and the interaction AN * EN. The second model included the genetic group of the calf, sex, AN, EN, and the interaction AN * EN. The genetic group of the cow and calf and the interaction AN * EN did not significantly affect body weight (p < 0.05). The average weaning weights of progeny were as follows: Aberdeen Angus bulls, 177.70 ± 3.28 kg; Red Angus, 180.31 ± 3.46 kg; Brangus, 181.48 ± 3.15 kg; Nellore, 175.43 ± 3.60 kg; and Wagyu, 173.16 ± 2.96 kg.
An Aerobic Exercise: Defining the Roles of Pseudomonas aeruginosa Terminal Oxidases

Field: Immunology and Microbiology (Life Sciences)

In this issue, Arai et al. (J. Bacteriol. 196:4206–4215, 2014, doi: http://dx.doi.org/10.1128/JB.02176-14 ) present a thorough characterization of these five complexes, enabling a more detailed understanding of aerobic respiration in this organism.
Research of an Innovative P2P-Based Botnet

Field: Computer Science (Physical Sciences)

The research recently focuses on the integration of peer-to-peer frame as incremental improvements to botnet. In hybrid P2P botnet, it is important to find a mechanism to select neighbor list for every super node, in order to improve stability of communication when some super nodes lose. At the same time, it needs to select high performance and nearest node as a super node, to provide command request and file transport for other ordinary nodes. In this paper, we propose a neighbor list selecting method based on Strongly Connected Graph and analysis a super node selecting mechanism based on AHP. Evaluation shows that this mechanism can increase coverage probability of commands and decrease average connection time (ACT) between super node and ordinary node.
The Impact of WTO Accession on Taiwan's GHG Emission: A Dynamic CGE Analysis

Field: Economics, Econometrics and Finance (Social Sciences)

This paper investigates the potential impact of China's and Taiwan's accession to the WTO on Taiwan's international trade, industrial structure, energy demand and greenhouse gas (GHG) emission during 2001-2005. Two large applied general equilibrium models, GTAP and TAIGEM, are used in this paper to simulate China's and Taiwan's WTO accession. TAIGEM (TAIwan General Equilibrium Model), a dynamic, multisectoral, applied general equilibrium model of the Taiwan’s economy is developed specifically to analyze climate change response issues. In this paper we use GTAP to provide the global context for the WTO accession, and TAIGEM to assess the detailed impacts on Taiwan. It shows that the comparative advantages of China and Taiwan are in different economic sectors. In average, Taiwan's economic growth will increase yearly at 0.4% above the baseline projection for the period 2001-2005. Service sector is expected to grow. Its share of real GDP will increase from 62.97% to 64.46%. In contrast, agriculture and industry sectors are the losers. In particular, sectors related to fossil fuel, cement, and iron and steel will contract due to less international competitiveness. With reduction of coal consumption and increasing share of gas and oil consumption, CO2 emission level is expected to be at the level of 296.6 million tons that is higher by 1.6 million tons than the baseline projection level at 295.0 million tons.
Multiple Control Stations in Packet Radio Networks

Field: Computer Science (Physical Sciences)

This paper presents a design recently implemented by the Packet Radio project for control of large networks. The network is built on a carrier sense, multiple access broadcast channel and is populated with mobile store and forward nodes known as packet radio units, or PRs. Until recently, the packet radio network operated with centralized routing controlled by one node, the station. To increase the size of the network and to provide redundant control a multiple station design, "multistation", was necessary. The PRs gather local connectivity information which is then forwarded to the controlling nodes (stations). Each station is responsible for up to 40 PRs located near it in connectivity and uses these PRs to communicate with other stations. Questions important to the development of multistation include: How are packet radios matched with controlling stations? How do stations find and communicate with each other? How are long routes crossing the borders of many stations determined, and how is their successful setup insured? How is control traffic minimized?
Current directions in active programmable network

Field: Computer Science (Physical Sciences)

The active programmable network (APN) has begun a new phenomenon in the logical view towards network in the Internet domain. Traditional technologies based on IP have viewed the network as a black box where the network is hidden from the upper layers. The advantage of this model is the simplicity and the robustness it can offer. However, this model may not be appropriate for the future applications of the Internet where the integration of services are expected. The APN can be considered as an alternative model where components within the network are open for programmability.

Comprehensive Study on Melting Process of Phase Change Material by Using Paraffin Coupled Finned Heating Plate for Heat Transfer Enhancement

Field: Energy (Physical Sciences)

Paraffin is a low-temperature phase change material, which is often used to recover and store heat in a solar thermal utilization system. This study aims to reveal the development and migration law of paraffin melting interface with time under the influence of a finned heating plate, as well as the heat transfer mechanism, and obtain the ways and methods to enhance the heat transfer in phase change material through visual experiments and numerical simulation. The research shows that once the paraffin with a high liquid fraction connects the mushy zone between the fin and the top wall, the vortexes in the mushy zone increases rapidly, which enhances the natural convective heat transfer in it, resulting in the rapid increase of liquid fraction. The lower the position of the fin, the longer the time required to form a mushy zone with a high liquid fraction between the fin and the top wall, and the later the phenomenon of rapid increase of liquid fraction occurs. Compared with changing the fin position, increasing the fin length has a greater effect on the paraffin melting rate. When other conditions remain unchanged, the inclination of fin and the effective length of fin in the horizontal direction jointly determine the melting rate of paraffin. The melting effect of paraffin is the best when the fin is inclined upward by 15°.
Microfluidic Approaches to Bacterial Biofilm Formation

Field: Immunology and Microbiology (Life Sciences)

Bacterial biofilms—aggregations of bacterial cells and extracellular polymeric substrates (EPS)—are an important subject of research in the fields of biology and medical science. Under aquatic conditions, bacterial cells form biofilms as a mechanism for improving survival and dispersion. In this review, we discuss bacterial biofilm development as a structurally and dynamically complex biological system and propose microfluidic approaches for the study of bacterial biofilms. Biofilms develop through a series of steps as bacteria interact with their environment. Gene expression and environmental conditions, including surface properties, hydrodynamic conditions, quorum sensing signals, and the characteristics of the medium, can have positive or negative influences on bacterial biofilm formation. The influences of each factor and the combined effects of multiple factors may be addressed using microfluidic approaches, which provide a promising means for controlling the hydrodynamic conditions, establishing stable chemical gradients, performing measurement in a high-throughput manner, providing real-time monitoring, and providing in vivo-like in vitro culture devices. An increased understanding of biofilms derived from microfluidic approaches may be relevant to improving our understanding of the contributions of determinants to bacterial biofilm development.
The Health Behavior Scale Developed for the Taiwanese with Chronic Illness

Field: Health Professions (Health Sciences)

The purpose of this study was to develop a Health Behavior Scale (HBS) to investigate health behavior amongst Taiwanese with a chronic illness. Results of a qualitative study and a literature review were used to inform the initial development of the 69-item HBS. Two studies were then undertaken to test the psychometric integrity of the scale. In the first study, data was gathered from 80 Taiwanese with a chronic illness and was subjected to item analysis and convergent validity analysis. The second study involved a convenience sample of 372 chronically ill Taiwanese and confirmatory factor analysis was conducted. Instrument analysis in the first study resulted in a 49-item HBS with Cronbach’s alpha of .92, and alpha coefficients .73-.91 for the three subscales respectively. Test-retest correlation of .82 (and .80-.86 for subscales) with a 6-week interval supported stability reliability. Content validity of the HBS was evaluated using a panel of experts and convergent validity was used to support the construct validity of the HBS. In the second study, the results of testing the measurement model of the Health Behavior Scale indicated good reliability and accounted for a large amount of variance. This study shows that the HBS has been employed in Taiwanese with chronic illness with remarkable reliability and validity.
Synthetic Channel Specifically Inserts into the Lipid Bilayer of Gram‐Positive Bacteria but not that of Mammalian Erythrocytes

Field: Chemistry (Physical Sciences)

Abstract A series of tubular molecules with different lengths have been synthesized by attaching Trp‐incorporated peptides to the pillar[5]arene backbone. The tubular molecules are able to insert into the lipid bilayer to form unimolecular transmembrane channels. One of the channels has been revealed to specifically insert into the bilayer of the Gram‐positive bacteria. In contrast, this channel cannot insert into the membranes of the mammalian rat erythrocytes even at the high concentration of 100 μ m . It was further demonstrated that, as a result of this high membrane selectivity, the channel exhibits efficient antimicrobial activity for the Gram‐positive bacteria and very low hemolytic toxicity for mammalian erythrocytes.
An Empirical Study on the Holiday Effect of China's Time-Honored Companies

Field: Economics, Econometrics and Finance (Social Sciences)

The stock segment of China's time-honored brand enterprises has an important position in our securities stock market. The holiday effect is one of the market anomalies that occur in the securities market, which refers to the phenomenon that the stock market has significantly different returns than other trading days around festivals. The study of the holiday effect of China's time-honored brand enterprises can provide fresh ideas for the revitalization of our time-honored brands and the revitalization of time-honored enterprises. This paper takes listed companies of China's time-honored brand enterprises as the research object and focuses on the impact of the holiday effect on listed companies of China's time-honored brands with the help of the event study, and empirically analyses the changes in the return of listed companies of China time-honored brands during the Spring Festival period from 2012 to 2021. The empirical results reveal that: the time-honored brand concept stocks have a significant post-holiday effect during the Chinese New Year period, the time-honored alcoholic beverage enterprises are more sensitive to the Chinese New Year reflection, while the holiday effect of the time-honored pharmaceutical manufacturing enterprises is not significant.
Modulation of unfolded protein response to endoplasmic reticulum stress causes a potent antiviral response in HSV infection corneal epithelial cells.

Field: Medicine (Health Sciences)

Herpes simplex viruses (HSV) are one of the most ubiquitous pathogens with approximately 90% global seroprevalence. Recurrent infections lead to painful ulcerative keratitis and lesions in the ocular, oro-facial and genital regions in latently infected individuals. Currently there is only one approved treatment, acyclovir, which acts via the inhibition of a single aspect of viral life cycle, viral DNA replication. Among the many cellular pathways tightly regulated by the virus during its infectious life cycle, the unfolded protein response (UPR) to endoplasmic reticulum (ER) stress is an important pathway that regulates viral protein synthesis and folding. In this study, we tested multiple small-molecule inducers and alleviators of ER stress to understand its effects on HSV-1 infection. Through immunofluorescence, western blotting and quantitative PCR, our results showed that while external induction of ER stress using tunicamycin reduces HSV viral spread and protein synthesis, the alleviation of ER stress using salubrinal increases and promotes viral replication and protein synthesis in human corneal epithelial cells. Our results align with the existing hypothesis that HSV requires host ER machinery to effectively translate and fold viral proteins during its life cycle and inhibition of this pathway can result in a potent antiviral response.

Summary form only given, as follows. This paper presents a broadband fixed delay compensation phase shifter that makes use of non-radiating longitudinal slots in the broad wall of a substrate integrated waveguide. The design concept is built up on the difference of propagation constants of TE10 mode and quasi-TEM mode, which are the fundamental modes of substrate integrated waveguide and slotted substrate integrated waveguide in our circuit, respectively. The proposed method is then validated by both theory and experiments.
Scurvy presenting primarily as gingival manifestation in a young child: a diagnostic dilemma

Field: Dentistry (Health Sciences)

Vitamin C deficiency, historically known as scurvy, was associated with sailors in the Victorian times, however, a global review in 2020 suggests it still exists in certain at-risk groups. A case is presented of a young non-verbal child with learning difficulties and on a restricted diet, in which the primary symptom was gingival inflammation. It posed a diagnostic dilemma due to the non-specific symptoms, and a delay in the diagnosis, until vitamin C deficiency was confirmed. Gingival inflammation is one of the common findings in vitamin C deficiency and dental professionals may be the first point of contact. The importance of dietary evaluation, identifying and looking for other signs and liaising with the medical colleagues are discussed. This case highlights the role of the dentist in identifying latent cases of vitamin C deficiency and to consider this as a differential diagnosis especially in certain at-risk groups.
The use of permitted additives and heat‐treatment to optimize the heat‐stability of skim milk and concentrated skim milk

Field: Agricultural and Biological Sciences (Life Sciences)

Changes in heat stability induced by forewarming and addition of permitted stabilizers have been investigated for skim milk, concentrated (22·5 per cent total solids) skim milk and reconstituted skim‐milk powder. Forewarming slightly reduced the heat stability of skim milk, but markedly improved the heat stability of concentrated skim milk. The effect of stabilizer addition was largely dependent on the initial pH of the milk and its position on the coagulation time/pH profile with respect to the maximum heat stability in the curve. It was shown that the combination of forewarming and addition of suitable stabilizers could induce a large increase in the heat stability of both skim and concentrated skim milk. Addition of stabilizers could likewise increase the heat stability of reconstituted ‘high‐heat’ skim‐milk powder, but was ineffective in improving the basic heat stability of non‐forewarmed milk and reconstituted ‘low‐heat’ skim‐mlk powder.
