Assessment of Household Food Security and Nutritional Status of Women in the Context of High Food Price in Addis Ababa
Creators: name: Birhane, Tesfaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Background: Since recently, the world's economic crisis, mainly the high food price is increasing the number of poor people and aggravating their living conditions. In big urban areas of Ethiopia like Addis Ababa where populations rely on market based household food supply, increasing price of food and nonfood commodities can threaten households' food security status. In many societies, women bear the brunt of the food price crisis. Thus, it is crucial to generate evidence about the food security of urban households and women's nutritional status during time of high food price. Objective: To assess households' food security status and nutritional status of women in the context of high food price in Addis Ababa City Methodology: A community based cross-sectional study using both quantitative and qualitative methods was conducted from January 18 to Feburary14, 2012. A total of 550 households were selected from three sub-cities of Addis Ababa using multi stage sampling technique. Food security status was assessed using Household Food Insecurity Access Score, and weight and height were also measured using standardized weight measuring scale and height measuring board. Data were collected using questionnaire based interview with household heads. Qualitative method using focus group discussion was employed to explore the possible effect of food price on household food security, and people's perception about food security. Result: This study found that 75% of households were generally food insecure and 23 % were already in hunger state. Reduction in meal size and shifting to poor quality/less expensive food types/ were common coping strategies to high food price used by households. Household income and educational status of household head were significant determinants of food security. Households with higher food insecurity score have lower dietary diversity and are less likely to consume high quality diets. About 12.7% of women in the sample were underweight while 26% were overweight or obese. Being overweight was significantly associated with better dietary diversity of households. Conclusion and Recommendation: The study revealed that about three fourth of households were food insecure which forced them to reduce their meal size and quality with nearly a quarter of households were suffered from hunger. Household food insecurity was common among the low income households and those headed by uneducated, daily wagers and government employed household heads. Beside subsidization of food items at affordable manner, policy makers should work on stabilization of food market, and create opportunities and capacities for households to increase their per capita income

Στο Κεφάλαιο 1 γίνεται μία σύντομη αναφορά στο φαινόμενο της υφαλμύρωσης, δηλαδή η περιγραφή του φαινομένου, οι αιτίες και οι συνέπειές του στο περιβάλλον, στην οικονομία και στον άνθρωπο. Στοιχεία για το παράκτιο τμήμα της Π.Ε. Ροδόπης, τα οποία συνδέονται με την εμφάνιση υψηλής αλατότητας δίνονται στο Κεφάλαιο 2, ενώ η διενέργεια των στατιστικών και υδρογεωχημικών μεθόδων περιγράφονται στο Κεφάλαιο 3. Στη συνέχεια, στο Κεφάλαιο 4 παρατίθενται τα αποτελέσματα που προέκυψαν από κάθε μέθοδο ξεχωριστά και γίνεται συνδυασμός όλων των μεθόδων για την αξιολόγηση των πηγών αλατότητας. Στο τελευταίο κεφάλαιο, στο Κεφάλαιο 5, εφαρμόζεται η κλασσική μέθοδος GALDIT για την εκτίμηση της τρωτότητας στη θαλάσσια διείσδυση, ενώ επίσης προτείνεται και εφαρμόζεται μία νέα παραλλαγή της μεθόδου, η οποία εστιάζει στην εκτίμηση της τρωτότητας σε διάφορες πηγές αλατότητας, χωρίς να περιορίζεται μόνο στη διείσδυση θαλασσινού νερού. Τέλος, καταγράφονται οι επιπτώσεις της υφαλμύρωσης στην περιοχή μελέτης και προτείνονται τρόποι για τον περιορισμό των επιπτώσεων ή/και την εξάλειψη του φαινομένου
description: For the present thesis, a sampling was conducted in the eastern coastal part of Prefecture of Rhodope for the expansion of the sampling network in the western part, which was created for the “Medsal” project from ELGO “Demeter”. In Chapter 1, a brief reference is made to groundwater salinization, specifically a description of this phenomenon, the causes and the effects on the environment, the economy and the human health. Details are presented about the coastal area of Rhodope, which are connected to the development of salinization, in Chapter 2, while the application of statistical and hydrogeochemical methods are described in Chapter 3. Then, in Chapter 4 the thesis presents the results from each method separately and in combination with the results from all methods, assessment of salinization sources are made. In the last chapter, Chapter 5, the classic GALDIT method was applied for the vulnerability assessment in seawater intrusion, while a new modification of GALDIT method was proposed and applied. The new modification of GALDIT method was not only restricted in seawater intrusion, but focuses on the vulnerability assessment in various salinity sources. Finally, the effects of the groundwater salinization in the study area are presented and methods are suggested for the impact reduction or/and the elimination of this phenomenon

description: Dynamic nuclear polarization (DNP) is capable of boosting signals in nuclear magnetic resonance by orders of magnitude by creating out-of-equilibrium nuclear spin polarization. The diffusion of nuclear spin polarization in the vicinity of paramagnetic dopants is a crucial step for DNP and remains yet not well understood. In this Letter, we show that the polarization of the electron spin controls the rate of proton spin diffusion in a DNP sample at 1.2 K and 7 T; at increasingly high electron polarization, spin diffusion vanishes. We rationalize our results using a 2 nucleus - 1 electron model and Lindblad s Master equation, which generalizes preexisting models in the literature and qualitatively accounts for the experimental observed spin diffusion dynamics.

description: La Cláusula de Caducidad en los contratos estales, corresponde a una de las sanciones más gravosa que contiene el estatuto de contratación nacional y es considerada de última ratio dentro de las medidas de vigilancia y control. No obstante, no puede perderse de vista que la misma cumple un cometido legítimo cual es garantizar la protección del interés público y asegurar la continuidad del servicio, buscando evitar la parálisis en la ejecución contractual mediante la sustitución de la persona del contratista. Por ello, el objeto general de esta investigación consistió en determinar cuáles son los mecanismos con los que cuenta la administración como alternativa a la declaratoria de la cláusula exorbitante de caducidad contractual en los casos de incumplimiento grave del contratista. Identificando las alternativas existentes en el derecho común que resultan aplicables a la contratación estatal que puedan ser igual de eficaces para asegurar la prestación de los servicios públicos o la continuación de una obra, que puedan ser aplicadas por la administración ante el advenimiento de la suspensión del contrato por incumplimiento.
description: The Sunset Clause in state contracts corresponds to one of the most burdensome sanctions contained in the national contracting statute and is considered last resort within the surveillance and control measures. However, it cannot be lost sight of that it fulfills a legitimate purpose which is to guarantee the protection of the public interest and ensure the continuity of the service, seeking to avoid paralysis in contractual execution by replacing the person of the contractor. Therefore, the general objective of this investigation was to determine what mechanisms the administration has as an alternative to the declaration of the exorbitant contractual sunset clause in cases of serious non-compliance by the contractor. Identifying the existing alternatives in common law that are applicable to state contracting that can be equally effective in ensuring the provision of public services or the continuation of a work, which can be applied by the administration before the advent of the suspension of the contract for breach.

description: Recently, a Dirac (particle-hole symmetric) description of composite fermions in the half-filled quantum Hall system was proposed [D. T. Son, Phys. Rev. X 5, 031027 (2015)], and we study its possible consequences on BCS (Cooper) pairing of composite fermions (CF's). One of the main consequences is the existence of anisotropic states in single and bilayer systems, which was previously suggested in Ref. [J. S. Jeong and K. Park, Phys. Rev. B 91, 195119 (2015)]. We argue that in the half-filled single layer the gapped states may sustain anisotropy, because isotropic pairings may coexist with anisotropic ones. Furthermore, anisotropic pairings with addition of a particle-hole (PH) symmetry breaking mass term may evolve into rotationally symmetric states, i.e. Pfaffian states of Halperin-Lee-Read (HLR) ordinary CF's. On the basis of the Dirac formalism, we argue that in the quantum Hall bilayer at total filling one, with decreasing distance between layers weak pairing of p-wave paired CF's is gradually transformed from Dirac to ordinary, HLR-like, with concomitant decrease in the CF number. Global characterization of low-energy spectrum based on the Dirac CF's agrees well with previous calculations performed by exact diagonalization on a torus. Finally, we discuss features of Dirac formalism when applied in this context.

description: This work presents a novel approach to water Cherenkov neutrino detector event reconstruction and classification. Three forms of a Convolutional Neural Network have been trained to reject cosmic muon events, classify beam events, and estimate neutrino energies, using only a slightly modified version of the raw detector event as input. When evaluated on a realistic selection of simulated CHIPS-5kton prototype detector events, this new approach significantly increases performance over the standard likelihood-based reconstruction and simple neural network classification.

description: A continuum elastic model of fullerenes is presented by utilizing the analogy between the closed carbon cages and elastic shells. We derive expressions for the curvature related strain energies Ep of the pentagonal protrusions. We propose to explain the observed sphericity of the carbon onions shells as opposed to the predicted protrusions around the pentagonal defects on the basis of our continuum elastic model of fullerenes. In our model the energy inherent in the pentagonal protrusions Ep is due to the stretching and bending of the shell and shown to be a function of the structural parameters. It also defines the upper limit on the size of the free-standing fullerenes. Using Ep and the topological arguments, we show that the pentagonal protrusions will be smoothed out, resulting in spherical shells of the carbon onions denoted as C60@C240@C540@C960@C1500 ,... .

description: Identifying the three-dimensional (3D) crystal-plane and strain-field distributions of nanocrystals is essential for optical, catalytic, and electronic applications. Here, we developed a methodology for visualizing the 3D information of chiral gold nanoparticles with concave gap structures by Bragg coherent X-ray diffraction imaging. The distribution of the high-Miller-index planes constituting the concave chiral gap was precisely determined. The highly strained region adjacent to the chiral gaps was resolved, which was correlated to the 432-symmetric morphology of the nanoparticles and its corresponding plasmonic properties were numerically predicted from the atomically defined structures. This approach can serve as a general characterization platform for visualizing the 3D crystallographic and strain distributions of nanoparticles, especially for applications where structural complexity and local heterogeneity are major determinants, as exemplified in plasmonics.

Qing China’s Legal Reform Thought before 1895: John Fryer and His “Western Learning” Dissemination in Shanghai during the Self-Strengthening Movement
Creators: name: Zhaorui Wang
Publisher: name: University of Chicago
Year: 2022

description: In this paper I will argue that legal reform as an agenda in Chinese modernization did not, as the mainstream opinion has believed, start from the 1901 policy reforms of the Qing Government, the so-called New Policy (清末新政), but rather from the Self-Strengthening Movement (洋務運動), which was encouraged by the translational work of John Fryer (Chinese name:傅蘭雅), an English missionary-turned-activist in late 19th century China. To make this argument I will first define what I mean by “legal reform” in this paper, before examining the evidence supporting the mainstream opinion in current scholarship. Then I will give a very short biography of Fryer, and consider the ways in which Fryer’s translation of Western political economy, law and other subjects, as well as his engagement with intellectuals and members of the Qing government through his active participation in a Shanghai school (which will be elaborated in part IV). What Fryer has done prepared the soil not for the spread of Christianity, but rather the transplantation of the Western legal system.
Risk perception of hepatitis b infection and uptake of hepatitis b vaccine among the nurses in private hospitals in Addis Ababa- a cross-sectional study

description: Background: Globally, hepatitis B infection is one of the major public health problems. It is the tenth leading cause of death among all diseases worldwide. Health care workers, especially nurses, are more exposed to the danger of acquiring the virus, due to their contact with blood or body fluids of infected person. The good thing is, hepatitis B is a vaccine preventable infection and this vaccine is safe, nearly 100% effective and has been available since 1982. Objectives: To assess the level of risk perception of hepatitis B infection and uptake of hepatitis B vaccine and the related factors among the nurses in private hospitals in Addis Ababa. Methods: Facility based cross-sectional survey was carried out among the nurses in private hospitals in Addis Ababa, between March and April 2018. Study participants were selected using simple random sampling technique. A total of 326 nurses were included in this study. Data was collected by using self-administered questionnaire, entered on Epidata version 3.1 and was exported to SPSS version 21 statistical software for analysis. Binary logistic regression analysis was done to identify important predictors. Result: Among the study participants, 62% of them had high risk perception of hepatitis B infection while the remaining 119(38%) had low risk perception. About half of the respondents, 149(49.7%) were vaccinated at least once in their life time. Out of the total respondents vaccinated, 121(40.4%) were completely vaccinated with the appropriate vaccination schedule. Study participants who were lower degree holder (diploma) were found to be 0.28 times less likely to take HB vaccine. Those who were in Pediatrics and Surgical/Oncology/Dental among the in-patient unit were 0.07 and 0.17 times respectively, less likely to take HB vaccine. Overall risk perception was also found to be statistically significant. Conclusion& Recommendation: This study revealed that the level of uptake of HB vaccine among the respondents, for at least once in their life time is about half. More than three-quarter of the total vaccinated, were completely vaccinated with appropriate vaccination schedule. Majority of the study participants of this study had high risk perception. Educational status, year of service or experience, being screened for HBsAg and the risk perception of HB infection were found to be independent predictors of level of uptake of hepatitis B vaccine of the respondents. Considering the importance of the HB vaccine, it should be made readily available at little or no cost through all the necessary channels and reminder should be sent for the next dose.

description: Σκοπός της παρούσας έρευνας ήταν να εξετάσει τις διαφορές στις μηχανικές και μορφολογικές ιδιότητες του Αχίλλειου τένοντα και την επίδραση της άσκησης σε τρείς διαφορετικές ηλικιακές ομάδες (προέφηβοι, έφηβοι, ενήλικες). Στην έρευνα συμμετείχαν 36 προέφηβοι , 24 έφηβοι και 34 νέοι ενήλικες άνδρες, 20,16 και 17 αθλητές και 16, 8 και 17 μη αθλητές, αντίστοιχα. Για την εκτίμηση της σκληρότητας του Αχίλλειου τένοντα οι εξεταζόμενοι εκτέλεσαν ισομετρική πελματιαία κάμψη σε ισοκινητικό δυναμόμετρο τύπου Cybex, και σε συνδυασμό με έναν υπέρηχο πραγματοποιήθηκε η καταγραφή της ροπής των πελματιαίων καμπτηρών και της μετατόπισης της μυοτενόντιας σύζευξης (MTJ). Η στατιστική ανάλυση των αποτελεσμάτων έγινε στο SPSS 27 με two-wayANOVA test και t-test για ανεξάρτητα δείγματα. Τα αποτελέσματα έδειξαν ότι η προπόνηση κατά την διάρκεια της ανάπτυξης επιδρά κυρίως από την ηλικία της ταχύτατης ανάπτυξης ύψους (PHV) και μετά, και οδηγεί σε μεγαλύτερη αύξηση τα σκληρότητας του τένοντα καθώς και της μέγιστης και της σχετικής δύναμης των πελματιαίων καμπτήρων, γεγονός το οποίο κάνει τον τένοντα πιο ανθεκτικό σε τραυματισμούς. Επομένως, η προπόνηση έχει ευεργετικό ρόλο στις μηχανικές και μορφολογικές ιδιότητες του ΑΤ κατά την διάρκεια της ώριμης ηλικιακής ανάπτυξης
description: The aim of this study was to investigate the differences in mechanical and morphological properties of Achilles tendon (AT)and the effect of exercise on 3 different age groups (preadolescents, adolescents, adults).In the study participated 36 preadolescents, 24 adolescents and 34 young adult,20,16 and 17 athletes and 16, 8 and 17 non athletes, respectively. To examine the Achilles tendon stiffness, the participants performed isometric plantar flexion in isokinetic dynamometer (Cybex). The torque was recorded by Cybex and the elongation of muscle-tendon junction using ultrasonography. For the statistical analysis used SPSS 27, a two-way ANOVA test and t-test for independent samples. The results showed that the long-term training during maturation it affects mainly from the age of peak height velocity (PHV) and after. Furthermore, the increase of stiffness of AT, max and relative force of plantar flexors seems to make the tendon more resistant to injury. Therefore, training has a beneficial role in the mechanical and morphological properties of the AT during maturation

description: Background: Despite the increasing population and unsatisfactory decline of neonatal mortality rate (NMR) less attention was given to Neonatal Intensive Care Unit (NICU) until recent years where a little effort is being made to improve the services provided. Currently there are 27governmental NICUs; Tikur Anbessa Specialized Teaching Hospital (TASTH) is one of these hospitals which serve as the main referral center. Regardless of the few number of NICUs there is complaints on the quality of care provided which might be due to a variety of reasons that are crucial for the survival of the neonates. Objectives: To assess the quality of care in TASTH, NICU in Addis Ababa, Ethiopia. Methods: Hospital based cross sectional study was used. The study has two categories of participants; primarily mother of the neonates who were available in the NICU during the data collection period and health professionals (n=35) working in the NICU. Sample size of the study on mothers was calculated using single population formula considering 50% prevalence which gives a total 384 participants. The unit was observed using inventory checklist from WHO Hospital Care for Mothers and Newborns: Quality Assessment and Improvement Tool. For the qualitative portion head of the unit (neonatologist), practicing neonatologist and the head nurse were included. Structured questionnaire was adopted from WHO Hospital care for mothers and new-born babies: quality assessment and improvement tool, and they were filled by the date collectors after obtaining an informed consent. Data was analyzed using SPSS version 20. P value of 0.05 was the cut off point for the level of significance. Adjusted odds ratio was used to show strength of association. Result: The study found that the quality of care that is provided in the neonatal intensive care unit in TASTH is inadequate. Overall service satisfaction was found to be 96.4% and 47.1% for the clients and health professionals respectively. Clients whom their neonates shared bed with others were 6.6 times not satisfied than those clients whom didn't, AOR (95%CI) 6.612[3.604, 10.109] Health professionals who don't think that there are a sufficient number of staffs were dissatisfied 3.15 times compared to those who think the number of staff is sufficient. AOR (95%CI) 150[0.050, 5.611] Conclusion and recommendation: Quality administration demands several strategies thus, it is fundamental to identify the problems, aiming at implementing effective actions, and monitoring the processes. The findings from this assessment would assist in scaling up of such units. More over the presence of national guideline which is specific to NICU would be a key to solve the problems associated with quality of care in NICUs.

description: Banchi & Crooks (Quantum, 2021) have given methods to estimate derivatives of expectation values depending on a parameter that enters via what we call a "perturbed" quantum evolution $x\mapsto e^{i(x A + B)/\hbar}$. Their methods require modifications, beyond merely changing parameters, to the unitaries that appear. Moreover, in the case when the $B$-term is unavoidable, no exact method (unbiased estimator) for the derivative seems to be known: Banchi & Crooks's method gives an approximation. In this paper, for estimating the derivatives of parameterized expectation values of this type, we present a method that only requires shifting parameters, no other modifications of the quantum evolutions (a "proper" shift rule). Our method is exact (i.e., it gives analytic derivatives, unbiased estimators), and it has the same worst-case variance as Banchi-Crooks's. Moreover, we discuss the theory surrounding proper shift rules, based on Fourier analysis of perturbed-parametric quantum evolutions, resulting in a characterization of the proper shift rules in terms of their Fourier transforms, which in turn leads us to non-existence results of proper shift rules with exponential concentration of the shifts. We derive truncated methods that exhibit approximation errors, and compare to Banchi-Crooks's based on preliminary numerical simulations.

description: Autophagy is a natural self-degradative process by which cells eliminate misfolded proteins and damaged organelles. Autophagy has been shown to have multiple functions in tumor cells that may be dependent on the tumor type and the treatment conditions. Autophagy can have a cytoprotective role and be thought of as a survival mechanism or be cytotoxic in nature and mediate cell death. Radiation, one of the primary treatments for many different types of cancer, almost uniformly promotes autophagy in tumor cells. While autophagy produced in response to radiation is often considered to be cytoprotective, radiation-induced autophagy has also been shown to mediate susceptibility to radiation. This review addresses the complexity of autophagy in response to radiation treatment in three different cancer models, specifically lung cancer, breast cancer and glioblastoma. A deeper understanding of the different roles played by autophagy in response to radiation should facilitate the development of approaches for enhancing the therapeutic utility of radiation by providing strategies for combination treatment with unique radiosensitizers as well as preventing the initiation of strategies which are likely to attenuate the effectiveness of radiation therapy.

description: We study the melting of domain walls in the ferromagnetic phase of the transverse Ising chain, created by flipping the order-parameter spins along one-half of the chain. If the initial state is excited by a local operator in terms of Jordan-Wigner fermions, the resulting longitudinal magnetization profiles have a universal character. Namely, after proper rescalings, the profiles in the noncritical Ising chain become identical to those obtained for a critical free-fermion chain starting from a step-like initial state. The relation holds exactly in the entire ferromagnetic phase of the Ising chain and can even be extended to the zero-field XY model by a duality argument. In contrast, for domain-wall excitations that are highly non-local in the fermionic variables, the universality of the magnetization profiles is lost. Nevertheless, for both cases we observe that the entanglement entropy asymptotically saturates at the ground-state value, suggesting a simple form of the steady state.

description: In this work, spherically symmetric thin-shell wormholes with a conformally invariant Maxwell field for $N$-dimensional $F(R)$ gravity and constant scalar curvature $R$ are built. Two cases are considered: symmetric wormholes and asymmetric ones in the scalar curvature. Their stability under radial perturbations is analyzed, finding stable solutions made of exotic matter for a given range of the parameters.

description: The motion of ionic solutes and charged particles under the influence of an electric field and the ensuing hydrodynamic flow of the underlying solvent is ubiquitous in aqueous colloidal suspensions. The physics of such systems is described by a coupled set of differential equations, along with boundary conditions, collectively referred to as the electrokinetic equations. Capuani et al. [J. Chem. Phys. 121, 973 (2004)] introduced a lattice-based method for solving this system of equations, which builds upon the lattice Boltzmann algorithm for the simulation of hydrodynamic flow and exploits computational locality. However, thus far, a description of how to incorporate moving boundary conditions into the Capuani scheme has been lacking. Moving boundary conditions are needed to simulate multiple arbitrarily-moving colloids. In this paper, we detail how to introduce such a particle coupling scheme, based on an analogue to the moving boundary method for the pure LB solver. The key ingredients in our method are mass and charge conservation for the solute species and a partial-volume smoothing of the solute fluxes to minimize discretization artifacts. We demonstrate our algorithm's effectiveness by simulating the electrophoresis of charged spheres in an external field; for a single sphere we compare to the equivalent electro-osmotic (co-moving) problem. Our method's efficiency and ease of implementation should prove beneficial to future simulations of the dynamics in a wide range of complex nanoscopic and colloidal systems that was previously inaccessible to lattice-based continuum algorithms.
Classical Limit of Higher-Spin String Amplitudes

description: It has been shown that a special set of three-point amplitudes between two massive spinning states and a graviton reproduces the linearised stress-energy tensor for a Kerr black hole in the classical limit. In this work we revisit this result and compare it to the analysis of the amplitudes describing the interaction of leading Regge states of the open and closed superstring. We find an all-spin result for the classical limit of two massive spinning states interacting with a photon or graviton. This result differs from Kerr and instead matches the current four-vector and the stress-energy tensor generated by a classical string coupled to electromagnetism and gravity respectively. For the superstring amplitudes, contrary to the black-hole case, we find that the spin to infinity limit is necessary to reproduce the classical spin multipoles.

Αιμοκάθαρση μικρότερης διάρκειας <4 ώρες/συνεδρία και η χρήση υψηλής συγκέντρωσης διαλύματος καλίου ήταν οι δύο παράγοντες που σχετίζονται με την υπερκαλιαιμία. Η παρούσα μελέτη δείχνει ότι μεταξύ των ασθενών που υποβάλλονται σε αιμοκάθαρση, τα ποσοστά επικράτησης και υποτροπής υπερκαλιαιμίας είναι πολύ υψηλά, αντανακλώντας τη μεγάλη ανάγκη εντοπισμού πιο αποτελεσματικών θεραπευτικών παρεμβάσεων μείωσης του καλίου σε αυτόν τον πληθυσμό υψηλού κινδύνου
description: The primary objective of the present study was to investigate the prevalence, recurrence, and seasonal variation of hyperkalemia, using monthly monitored potassium catalysis measurements during the week taken over a 1-year period in a group of 149 patients with ESKD who received maintenance dialysis three times a week. A secondary objective was to investigate the association of hyperkalaemia at any given time with many demographic, clinical, and dialysis-related parameters. The prevalence, recurrence and seasonal variation of hyperkalemia were assessed using three predetermined potassium thresholds. Shorter duration of dialysis <4 hours / session and the use of a high concentration of potassium solution were the two factors associated with hyperkalaemia. The present study shows that among patients undergoing dialysis, the prevalence and recurrence rates of hyperkalemia are very high, reflecting the great need to identify more effective potassium-lowering therapies in this high-risk population

description: A new series of 6,8-halo-substituted-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-one/-thione and 6,8-halo-substituted 5-methyl-2H-[1,2,4]triazino[5,6-b]indol-3(5H)-one/-thione (5a-5l) were designed and synthesized keeping in view of the structural requirement of pharmacophore. The above compounds were characterized by thin layer chromatography and spectral analysis. Anticonvulsant activity of the synthesized compounds was evaluated by the maximal electroshock (MES) test. Neurotoxicity and CNS depressant effects were evaluated by the rotarod motor impairment and Porsolt’s force swim tests, respectively. A computational study was carried out, for calculation of pharmacophore pattern, prediction of pharmacokinetic properties and toxicity properties. The above study revealed that the compounds 8-chloro-2H-[1,2,4]triazino[5,6-b]indol-3(5H)-one (5e), 6,8-dibromo-2H-[1,2,4]triazino[5,6-b]indol-3(5H)-one (5i) and 6,8-dibromo-5-methyl-2H-[1,2,4]triazino[5,6-b]indol-3(5H)-one (5k) possess excellent anticonvulsant activity in the series with little CNS depressant effect and no neurotoxicity as compared to standard drugs phenytoin and carbamazepine.

description: A growing body of work studies Blindspot Discovery Methods ("BDM"s): methods that use an image embedding to find semantically meaningful (i.e., united by a human-understandable concept) subsets of the data where an image classifier performs significantly worse. Motivated by observed gaps in prior work, we introduce a new framework for evaluating BDMs, SpotCheck, that uses synthetic image datasets to train models with known blindspots and a new BDM, PlaneSpot, that uses a 2D image representation. We use SpotCheck to run controlled experiments that identify factors that influence BDM performance (e.g., the number of blindspots in a model, or features used to define the blindspot) and show that PlaneSpot is competitive with and in many cases outperforms existing BDMs. Importantly, we validate these findings by designing additional experiments that use real image data from MS-COCO, a large image benchmark dataset. Our findings suggest several promising directions for future work on BDM design and evaluation. Overall, we hope that the methodology and analyses presented in this work will help facilitate a more rigorous science of blindspot discovery.
