A Study on the Impact of Distance-Based Value Loss on Transmission Network Power Flow Using Synthetic Networks

This paper presents a methodology for rapid generation of synthetic transmission networks and uses it to investigate how a transmission distance-based value loss affects the overall grid power flow. The networks are created with a graph theory-based method and compared to existing energy systems. The power production is located on these synthetic networks by solving a facility location optimization problem with variable distance-based value losses. Next, AC power flow is computed for a snapshot of each network using the Newton–Raphson method and the transmission grid power flow is analyzed. The presented method enables rapid analysis of several grid topologies and offers a way to compare the effects of production incentives and renewable energy policies in different network conditions.

The Relationship Of Exposure To Cigarette Smoke In Pregnant Mothers To The Weight Of Newborn In Bhayangkara Palembang Hospital In 2021

Abstrak Background:. Exposure to cigarette smoke can affect low birth weight in mothers who are exposed to cigarette smoke. Low birth weight (LBW) babies are babies with a birth weight of less than 2500 grams. Objectives: To analyze the relationship between age, parity, gestational distance, education, occupation, exposure to cigarette smoke on the weight of newborns in mothers who gave birth. Methods: This research is analytic with a cross-sectional approach. The population and sample are 50 using total sampling technique. Results: The results of the statistical test showed that the variables that were statistically significantly related to the birth weight of newborns were age, parity, education, and exposure to cigarette smoke with ap value <0.05, while the variable distance between pregnancy and occupation did not have a significant relationship. with p value> 0.05. Conclusion: there is a significant relationship between exposure to cigarette smoke and the weight of newborns at Bhayangkara Hospital Palembang in 2021. Keywords: low birth weight, pregnant, passive smoking

Random attention can explain apparent object choice behavior in free-walking blowflies

Flies are often observed to approach dark objects. To a naive observer they seem to pay selective attention to one out of several objects although previous research identified a reflex-like fixation behavior integrating responses to all objects as possible underlying mechanism. In a combination of behavioral experiments and computational modelling, we investigate the choice behavior of flies freely walking towards an arrangement of two objects placed at a variable distance from each other. The walking trajectories are oriented towards one of the objects much earlier than predicted by a simple reactive model. We show that object choice can be explained by a continuous control scheme in combination with a mechanism randomly responding to the position of each object according to a stochastic process. Although this may be viewed as a special form of an attention-like mechanism, the model does not require an explicit decision mechanism or a memory for the drawn decision.

Reasons to use cilostazol

Occlusive atherosclerosis of the lower limbs in the initial stage is characterized by symptoms of intermittent claudication with a variable distance depending on the severity of its changes. As a progressive disease, it may lead to the obstruction of the arteries of the lower extremities and the formation of a collateral circulation network in the form of natural by-passes of obstructed sections of the arteries. Disease development is accelerated by: older age, male sex, smoking, diabetes, dyslipidemic disorders and arterial hypertension. One of the effective forms of treatment of chronic lower limb ischemia in the course of atherosclerosis is pharmacotherapy with cilostazol.

Dynamic changes of scleral spur length in different accommodation stimuli states

This study aimed to evaluate the scleral spur length (SSL) in response to different accommodation stimuli states, as well as the correlation with Schlemm’s canal (SC) and trabecular meshwork (TM). 74 children were recruited for this study. The 0D, − 4D, and − 8.0 D accommodation stimuli state was achieved by looking at a variable distance optotype. The ciliary muscle (CM), scleral spur (SS), SC, and TM were imaged by swept-source optical coherence tomography. The SSL (Method III) increased significantly from 221.56 ± 30.74 μm at base state to 234.99 ± 30.11 μm at − 4D accommodation stimuli state (p = 0.028) and increased to 250.09 ± 29.87 μm at − 8D accommodation stimuli state (p = 0.011). Method III had the largest areas under receiver operating characteristic (ROC) curves (0.798, 95% CI 0.721–0.875). Moreover, CM 1, SC, and trabecular meshwork length (TML) were significantly correlated with SSL (Method III) (p < 0.05). These findings suggest that the contractile ability and compliance of the SS play an important role in maintaining the morphology of the SC. Moreover, the force of accommodation regulates the SC size by increasing the length of SS.

An Analysis of Determinant Factors in Agricultural Trade between India and ASEAN

Considering the significance of trade relation between India and ASEAN, the present study was conducted to analyze the determinants of India-ASEAN trade in agricultural products. This study incorporated HS 2-digit codes from 01 to 24 chapters, which constituted 85 percent of the total chapter falling under agricultural products. To perceive the significance of ASEAN as a major trading partner, shares of India's trade with ASEAN relative to the world was computed via trade intensity approach. Furthermore, the gravity model was employed to witness the determinants of agriculture trade between the two trading partners. The study found that the GDP of ASEAN and India, the common border between the two trading blocs, was positive and significant. The variable distance and landlocked was observed to be negative and significant, which confirmed that trade would decrease if distance increases and if the country was landlocked, respectively. Interestingly, variables like FTA, GDP of India, common language, and common colony showed no significant effect on the bilateral trade.

Dynamic Changes of Scleral Spur Length In Different Accommodation States

This study aimed to evaluate the scleral spur length in response to different accommodation stimuli states, as well as the correlation with Schlemm’s canal and trabecular meshwork. 74 children were recruited for this study. The 0D, -4D, and − 8.0 D accommodation state was stimulated by looking at a variable distance optotype. The ciliary muscle, scleral spur, Schlemm’s canal, and trabecular meshwork were imaged by swept-source optical coherence tomography. The scleral spur length increased with accommodation stimulation (p < 0.05). Method I was 127.97 ± 20.32 µm, 138.29 ± 20.11 µm, and 150.73 ± 21.75 µm at 0D, -4D and − 8D, respectively. Method II was 158.15 ± 19.97 µm, 168.47 ± 18.72 µm, and 179.79 ± 20.83 µm at 0D, -4D and − 8D, respectively. Method III was 221.56 ± 30.74 µm, 234.99 ± 30.11 µm, and 250.09 ± 29.87 µm at 0D, -4D and − 8D, respectively. Method III had the largest areas under ROC curves (0.798, 95% CI 0.721–0.875). Moreover, ciliary muscle 1, Schlemm’s canal, and trabecular meshwork length were significantly correlated with SSL (Method III) (p < 0.05). These findings suggest that the contractile ability and compliance of the scleral spur play an important role in maintaining the morphology of the SC. Moreover, the force of accommodation regulates the SC size by increasing the length of SS.
