Optimal PMU placements using sea lion optimization for adaptable distribution system

The technological advancements and policy reformations make the electric power distribution system an active network. The modern power system operational regulations encourage coordinated network operations among various entities and customer participation. Unlike traditional operational environments, real-time monitoring has become a mandate for secure and reliable operations. Phasor Measurement Units (PMU) is the most reliable data acquisition tool, and their application for State Estimation (SE) has already been proven. This work extends the application of PMUs for the distribution system. A multi-objective optimization framework is proposed considering the optimal placement of PMU, network reconfiguration, and topology expansion. A novel optimization tool, the sea lion optimizer has been chosen to address the developed optimization problem. The proposed operational model is employed in IEEE RBTS-2 bus system, IEEE 33 node system and 69 node radial distribution network. Numerical results provide new insights into PMUs role in enhancing distribution network operations. The statistical indices confirm that the intended optimizer performs well in the chosen highly constrained optimization environment.
Knee and Peri-Knee Tissues of Post Mortem Donors Are Strategic Sources of Mesenchymal Stem/Stromal Cells for Regenerative Procedures

Tissues of post mortem donors represent valuable alternative sources for the isolation of primary cells with mesenchymal stem/stromal cell (MSC)-like properties. However, the properties of primary cells derived from different tissues and at different post mortem times are poorly recognized. Here, we aim to identify the optimal tissue source between three knee and peri-knee tissues for the isolation of primary cells with MSC-like properties, and to define the influence of the time post mortem on the properties of these cells. We harvested tissues from subchondral bone marrow, synovium and periosteum from 32 donors at various post mortem times. Primary cells were evaluated using detailed in vitro analyses, including colony formation, trilineage differentiation, immunophenotyping and skeletal stem cell marker-gene expression profiling. These data show that the primary cells with MSC-like properties isolated from these three tissues show no differences in their properties, except for higher expression of CD146 in bone-marrow cells. The success rate of the primary cell isolation is dependent on the post mortem time. However, synovium and periosteum cells isolated more than 48 h post mortem show improved osteogenic and chondrogenic potential. This study suggests that knee and peri-knee tissues from donors even 3 days post mortem are strategic sources of MSCs for regenerative procedures.
Longitudinal tracking of axonal loss using diffusion magnetic resonance imaging in multiple sclerosis

Abstract Axonal loss in the CNS is a key driver of progressive neurological impairments in people with multiple sclerosis. Currently, there are no established methods for tracking axonal loss clinically. This study aimed to determine the sensitivity of longitudinal diffusion MRI-derived fibre-specific measures of axonal loss in people with multiple sclerosis. Fibre measures were derived from diffusion MRI acquired as part of a standard radiological MRI protocol and were compared (i) to establish measures of neuro-axonal degeneration: brain parenchymal fraction and retinal nerve fibre layer thickness and (ii) between different disease stages: clinically isolated syndrome and early/late relapsing–remitting multiple sclerosis. Retrospectively identified data from 59 people with multiple sclerosis (18 clinically isolated syndrome, 22 early and 19 late relapsing–remitting) who underwent diffusion MRI as part of their routine clinical monitoring were collated and analysed. Twenty-six patients had 1-year and 14 patients had a 2-year follow-up. Brain parenchymal fraction was calculated from 3D MRI scans, and fibre-specific measures were calculated from diffusion MRI using multi-tissue constrained spherical deconvolution. At each study visit, patients underwent optical coherence tomography to determine retinal nerve fibre layer thickness, and standard neurological assessment expanded the disability status scale. We found a significant annual fibre-specific neuro-axonal degeneration (mean ± SD = −3.49 ± 3.32%, P < 0.001) that was ∼7 times larger than the annual change of brain parenchymal fraction (−0.53 ± 0.95%, P < 0.001), and more than four times larger than annual retinal nerve fibre layer thinning (−0.75 ± 2.50% P = 0.036). Only fibre-specific measures showed a significant difference in annual degeneration between the disease stages (P = 0.029). Reduced brain parenchymal fraction, retinal nerve fibre layer thickness and fibre-specific measures were moderately related to higher expanded disability status scale (rho = −0.368, rho = −0.408 and rho = −0.365, respectively). Fibre-specific measures can be measured from data collected within a standard radiological multiple sclerosis study and are substantially more sensitive to longitudinal change compared with brain atrophy and retinal nerve fibre layer thinning.
Broadband Conductor Backed-CPW With Substrate-Integrated Coaxial Line to SIW Transition for C-Band

This brief describes a transition from conductor-backed-coplanar waveguide (CB-CPW) with substrate-integrated coaxial line (SICL) to substrate integrated waveguide (SIW). The transition is designed for the C-band frequency range. The CB-CPW slot lines play the main role in widening the bandwidth. These CPW slot lines are providing excitation of both even and odd mode waves in SIW, which improves the impedance bandwidth. Using the proposed concept, the measured single-mode fractional impedance bandwidth of 63.34%, the minimum insertion loss of 0.16 dB, and the overall loss below 25% are achieved. The simulated results are found to be in good agreement with the experimental ones obtained for the prototype developed in the laboratory.
Choice of Open Source Software Licenses: An Adaption to the Commercial Involvement

This paper tries to explore the mechanism of the choices of Open Source Software (OSS) Licenses. The benignant licensor choose between the restrictive and permissive licenses by considering how the commercial contributor reacts to the choice of OSS licenses to make the OSS project best supported with smallest damage the integrity of the OSS community. The licensor's choice of licenses is jointly determined by four factors: the OSS project's involvement benefit and its dependency on licensing, hijacking beneit and expected life time. Generally speaking, the licensing choices of OSS projects are qutie diversified. Both licensing triviality and licensing dilemma exist and this paper predicts a permissive trend in the future.
PENGARUH WAKTU AGING TERHADAP SIFAT HIDROFOBISITAS SILIKA XEROGEL TERMOFIDIFIKASI TRIMETILKLOROSILAN (EFFECT OF AGING TIME ON THE HYDROPHOBICITY OF SYNTHESIZED TRIMETHYLCHLOROSILANE-MODIFIED SILICA XEROGE)

Silica xerogel is a multi-functional material that is useful in many industrial applications. In this research, we synthesized surface-modified silica xerogel and studied the effect of aging time, i.e., 0, 3, 6, 12, and 18 hours to the hydrophobicity of the synthesized material. The synthesis was conducted by the sol-gel method using sodium silicate precursors and a citric acid catalyst. Meanwhile, the surface modification was carried out through the silylation reaction using trimethylchlorosilane (TMCS) reagent. The resulting materials were characterized using infrared spectrophotometry (FTIR) and X-ray diffraction (XRD) methods. Hydrophobicity was measured by the contact angle formed by the water droplet with the xerogel surface and the spreading time of the droplet to be dispersed entirely on the surface. The silica xerogel produced at all aging time variations has an amorphous phase, characterized by 2θ = 22-26o of the XRD pattern. Si-CH3 and C-H vibrations at 848 cm-1 and 2962 cm-1 present in the FTIR spectrumconfirm the success of surface modification. The increasing aging time enhances the contact angle and spreading time of water droplets on xerogels, viz., 130o to 135o,and 3h 10min to 3h 28 min, respectively. Thus, the xerogels produced by this research are hydrophobic.
Case study of a pod village for women experiencing homelessness: Learned lessons through residents’ experience

ABSTRACT The Kenton Women’s Village is the first city-sponsored pod village for people experiencing homelessness in Portland, Oregon. The village features individual sleeping pods and shared common facilities, and is managed by a local nonprofit organization. Villages have historically been self-governed communities borne of grassroots activism but have become increasingly of interest to nonprofits and municipalities seeking to address homelessness. As the village model proliferates throughout the United States, significant research that centers villager experience to inform the design, operations, and governance structures of future villages is needed. These interviews with the residents of Kenton Women’s Village revealed several themes around villagers’ experiences and perceptions of their pods, life in the village, and the surrounding community. This initial exploration contributes to our understanding of the managed pod village model and may inform the design of future villages as well as research with other pod villages across the Portland metro area.
UC Merced Proceedings of the Annual Meeting of the Cognitive Science Society

People learn new categories on a daily basis, and the study of category learning is a major topic of research in cognitive science. However, most prior work has focused on how people learn categories over abstracted, artificial (and usually perceptual) representations. Little is known about how new categories are learnt for natural objects, for which people have extensive prior knowledge. We examine this question in three pre-registered studies involving the learning of new categories for everyday foods. Our models use word vectors derived from large-scale natural language data to proxy mental representations for foods, and apply classical models of categorization over these vectorized representations to predict participant categorization judgments. This approach achieves high predictive accuracy rates, and can be used to identify the real-world settings in which category learning is impaired. In doing so, it shows how existing theories of categorization can be used to predict and improve everyday cognition and behavior.
Fattening performance, carcass traits, and profitability of Aberdeen Angus and Holstein Friesian bulls in Turkey

The aim of this study was to compare Aberdeen Angus (AA) and Holstein Friesian (HF) bulls in Turkey based on fattening performance, carcass properties, and production costs. In the trial, 105 AA and 105 HF 10- to 12-month-old bulls with a mean initial bodyweight (IBW) of 302 kg were used. The bulls were distributed into 14 paddocks in groups of 15 based on their IBW at an open-shed facility in İzmir. The bulls were fed different rations for the grower and finisher periods for 90 days each, but otherwise were kept under similar conditions. At the end of the finishing period, the animals were slaughtered and carcass characteristics, organ weights, quality of meat, and meat production costs were evaluated. In terms of fattening performance, the AA bulls were superior to the HF bulls. The ultimate pH of the Longissimus dorsi in the AA bulls was lower than in the HF bulls and the sensory characteristics of the AA bulls were higher. Production costs were higher for the AA bulls, but so too were income over feed costs (IOFC), making the AA bulls more profitable. Thus, it might be concluded that beef breed bulls that mature quickly, such as AA, are more advantageous for meat production in Turkey than HF bulls, which are a by-product of the dairy industry.
The syntax of generics and the absence of generic articles

Cross-linguistically, no language has a dedicated generic article. To address why this is, I decompose GEN into its quantificational and modal components and locate them inside nominal structure. Adopting an event licensing analysis of pre- and post-verbal bare subjects in Modern Hebrew, I use the restriction of pre-verbal bare subjects to generic interpretations and unacceptability of pre-verbal bare singulars to argue that the quantificational component of GEN is best analyzed as a D-quantifier. Evidence from adnominal conditionals further identifies a modal source for GEN within the nominal, which I suggest is adjectival and derived from a reduced relative clause source. I propose that the formation of generic articles is blocked by the non-local (e.g. non-spanning) relationship between these quantificational and modal components.

Neural Quadratic Assignment Programming for Sentence Matching

Studies have shown that both the syntactic 001 structures and words’ semantics are impor-002 tant for sentence matching. Existing stud-003 ies usually model the syntactic structures and 004 word semantics separately, resulting in match-005 ing models that overlook the relations and de-006 pendencies between syntactic structures and 007 semantic meanings. How to jointly model 008 the syntactic and semantic information has 009 become a challenging problem in sentence 010 matching. To address the issue, we formal-011 ize sentence matching as a problem of as-012 signing the word of one sentence to that of 013 another sentence, with the costs determined 014 by the differences between the correspond-015 ing syntactic structures and word embedding 016 similarities. The proposed method, referred 017 to as neural quadratic assignment program-018 ming for sentence matching (NQAP-SM), rep-019 resents the syntactic structures and semantic 020 matching signals as an association graph. Solv-021 ing the relaxed quadratic assignment program-022 ming (QAP) on this association graph achieves 023 the ﬁnal matching score. Experimental re-024 sults on three public datasets demonstrated 025 that NQAP-SM can outperform the state-of-026 the-art baselines in an effective and efﬁcient 027 way. The analysis also showed that NQAP-SM 028 can match sentences in an interpretable way. 029
Study of Prophylactic Action of Linseed Oil against Acetaminophen Induced Oxidative Stress and Liver Damage in Albino Rat

The protection conferred by linseed oil against acetaminophen (APAP) induced oxidative stress and liver damage has been evaluated in adult albino rat. Hepatotoxicity has been evaluated with the indication of elevated levels of enzymatic activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and bilirubin level in acetaminophen administered values as compared with control values. Co-treatment with linseed oil significantly restored the elevated levels of hepatic serum markers ALT, AST and ALP. This may result from cellular leakage due to peroxidative damage of the membrane. Significant reduction in antioxidant activities of SOD, GSH, CAT and GPx were obtained as compared with control values. At normal conditions, the body defense mechanism against oxidative stress, marked by endogenous antioxidant enzymes, such as SOD, GSH, CAT and GPx prevent cells damages induced by free radicals. The protective effects of linseed oil are dose and tissue-dependent, due to differences in the inherent susceptibility of each tissue in rat. Remarkable elevation in bilirubin level and reduced level of cholesterol in comparison to control group of rats were found in the study. While lowered the bilirubin level and higher the cholesterol level when compared with APAP treated group is attributed to hepato-cellular damage. Linseed supplementation in group III has returned the levels of bilirubin and total cholesterol to almost the same levels as the control while cholesterol decreased slightly below the control. The elevated bilirubin level in liver implies the overwhelming influence of oxidative stress generated by the APAP and likely due to the failure of antioxidant defense mechanisms. Importantly, linseed oil lowered the changes in total cholesterol level in the combination of acetaminophen. Acetaminophen-induced liver injury has also been marked by lipid oxidation. Thus, the augmented antioxidant enzymes levels in liver tissues of rat treated with linseed oil implies and justifies the antioxidant property of the oil.
What Determines Continuous Performance Task Performance ?

The Continuous Performance Task (CPT) is widely used as an indicator of cognitive dysfunction in schizophrenia. It is still unclear, however, exactly what this test measures. We examined the contribution of motor speed, reaction time measures, mental effort, and level of psychopathology to the performance on a doublestimulus CPT. This study included schizophrenia patient groups, depressive patient groups, and patient and normal control groups. Subjects were retested twice: once after 1 week and again at 3 months. In patients with schizophrenia or depression, the sensitivity measure (d') was strongly and consistently associated with motor speed and with the standard deviation of reaction times (response variability) to target stimuli. The association with response variability was also found at followup tests in the control groups. We conclude that in patients with schizophrenia or depression, the sensitivity measure of a doublestimulus CPT is associated with cognitive mechanisms that determine motor proficiency and response variability.

The Relationship between Corporate Social Responsibility and Firm Performance; Case of Kilimanjaro Airport Development Company, Tanzania

Corporate social responsibility has been in the cycle of intensive discussion among scholars on whether when practised has any effect on the firm’s performance. Some firms especially small ones tend to ignore the concept of corporate social responsibility while others take pride and fully involve themselves. The question has been whether it has any positive effect on the overall firm performance. The purpose of the study was to determine the relationship between corporate social responsibility and the performance of Kilimanjaro Airports Development Company (KADCO). The study explored different financial and non-financial aspects of KADCO’s performance. A descripto-explanatory research design was used covering a stratified simple random sample of 377 respondents drawn from a target population of 20,000. The collected data was analysed using descriptive and inferential statistical tools. Whereas means and standard deviation were used to determine and explain variable characteristics, inferential statistics was used to establish and explain variable relationships and making predictions (inferences) from the sample data. The study established a statically significant and positive relationship between corporate social responsibility and performance of Kilimanjaro Airport Development Company. The relationship between discretionary social responsibility and performance of Kilimanjaro Airport Development Company was established at r=. 692, p=. 000. The effect of ethical social responsibility on performance was positive and significant at 0.691, p=. 000. The effect of legal social responsibility on performance was established at 0.645, p=. 000 while that of economic social responsibility was established at 0. 618. Therefore, all independent variables had a positive influence on performance of Kilimanjaro Airport Development Company. The study recommends that Kilimanjaro Airport Development Company should continue to engage itself in economic social responsibility, be ethical and not involving in illegal business that could be detrimental to its corporate image. Further the company should continue to maintain its discretionary social responsibility as all of its variables have a positive correlation with performance.
Machine learning for track reconstruction at the LHC

The planned upgrade of the LHC to its High-Luminosity counterpart (HL-LHC) circa 2027 will bring about a drastic increase in instantaneous luminosity, pileup, and trigger rates. Currently, most LHC experiments use Kalman filter based track reconstruction algorithms which exhibit outstanding physics performance but scale poorly with the amount of data produced per bunch crossing. Therefore, the high energy physics community is currently performing intensive R&D to commission new or improved algorithms for this crucial data reconstruction task. This article presents many approaches such as running existing Kalman filter algorithms on accelerated hardware and overhauling the current approaches with machine learning techniques. A new algorithm testbed for research in track reconstruction, ACTS, is also discussed.
200 Mb/s visible optical wireless transmission based on NRZ-OOK modulation of phosphorescent white LED and a pre-emphasis circuit

We present a high-speed visible light communication(VLC) link that uses a commercially available phosphorescent white light-emitting diode(LED). Such devices have few megahertz bandwidth due to the slow response of phosphorescent component,which severely limit the transmission data rate of VLC system. We propose a simple pre-emphasis circuit. With blue-filtering and the pre-emphasis circuit,the bandwidth of VLC system can be enhanced from 3 to 77.6 MHz,which allows non-return-to-zero on-off-keying(NRZ–OOK) data transmission up to 200 Mb/s with the bit error ratio of 5.3 × 10-7 which is below 10-6. The VLC link operates at the room illumination level of ~1000 lx at 1.1 m range using a single 1 W white LED.
Integrated Reading-writing Classroom in Russia

Writing a composition on a literary topic has traditionally been an integral part of Russian education. However, as this chapter argues, the methods of writing pedagogy in literature classes both in first language (L1) and foreign language (FL) instruction have not evolved much since the Soviet times. Most students are still used to passive learning and to prescriptive teaching models. Similar to Russian youth back in the 1990s, today’s students seem to have learned that there are authorities that shouldn’t be questioned: the authority of the author, of a renowned literary critic, of a tradition, or of a teacher. Even when they formulate their thoughts autonomously, they often seem to search for one “true” interpretation, as well as for one main didactic function of the text. In this chapter, I examine the challenges that my students meet while confronting Western methods of writing pedagogy and advocate for substituting the traditional methods of teaching literature and writing with more liberating and creative practices. In particular, I discuss how I attempt to break with students’ perception of a teacher as knowledge-producer and encourage them to challenge and question traditional “authorities” and interpretations. Drawing on my experience of teaching a comparative literature class, “Drama and theatre”, I argue that a reader-response approach to interpreting literature in tandem with performance theory and practice can have a transformative impact on students’ writing, facilitating their interpretative, analytical, and creative skills.
