Explain Your Move: Understanding Agent Actions Using Specific and Relevant Feature Attribution

As deep reinforcement learning (RL) is applied to more tasks, there is a need to visualize and understand the behavior of learned agents. Saliency maps explain agent behavior by highlighting the features of the input state that are most relevant for the agent in taking an action. Existing perturbation-based approaches to compute saliency often highlight regions of the input that are not relevant to the action taken by the agent. Our proposed approach, SARFA (Specific and Relevant Feature Attribution), generates more focused saliency maps by balancing two aspects (specificity and relevance) that capture different desiderata of saliency. The first captures the impact of perturbation on the relative expected reward of the action to be explained. The second downweighs irrelevant features that alter the relative expected rewards of actions other than the action to be explained. We compare SARFA with existing approaches on agents trained to play board games (Chess and Go) and Atari games (Breakout, Pong and Space Invaders). We show through illustrative examples (Chess, Atari, Go), human studies (Chess), and automated evaluation methods (Chess) that SARFA generates saliency maps that are more interpretable for humans than existing approaches.

Adolescent Deliberate Self-Harm Ther- apies with the Family Inclusion

Deliberate self-harm (DSH) is a rapidly negative phenomenon. Although participants include multiple age groups, DSH vastly effects the adolescent population. Adolescent DSH is not solely a causation of mental health disorders, DSH has been numerously connected to healthy adolescent population through multiple community and school based research as a maladaptive coping strategy. Thus, adolescent DSH potentially affects vast numbers, not restricted to participants but including parents and family members. The concept for this study was to collate frequent therapies employed to manage adolescent DSH, therapeutic content, and potential success. A systematic literature review was conducted to compile frequent therapies employed to manage adolescent DSH, from multiple databases. Meta-summary analysis was employed, and the subsequent source studies coded into according themes. Multiple therapies are employed to manage adolescent DSH, with Cognitive Behavioural Therapy (CBT), Dialectic Behavioural Therapy (DBT), Family Based Therapy (FBT), Multisystemic therapy (MST), and No-Harm Contracts (NHC) the most commonplace. In conclusion a paucity of research is available based solely upon adolescent DSH, thus additional research would benefit this age population and the type of intervention therapy best suited to manage adolescent DSH.
PROTEIN SOURCES AND/OR ENZYMES EFFECTS ON BROILER PERFORMANCE AND PHYSIOLOGICAL STATUS

The aim of this study was to investigate the synergism of protein sources (plant or animal) and enzymes in diet on broiler performance, gastric enzymes activity, some blood parameters and histological observations. A total number of 270 one day unsexed Hubbard chicks were distributed into 6 equal groups. Each group has 3 replicates of 15 birds each. The first group served with plant source protein, the second one served with animal source protein, the rest 4 groups were supplemented with 100 or 200mg commercial enzymes per kg diet (plant or animal source of protein). Our results indicated that the benefits of the use of 100mg enzyme per Kg plant source of protein in diets on broiler performance, economic efficiency and increase in gastric enzymes activities (when comparing with the rest of groups) which explain the improvements in the FCR. The current trial indicated also, that broiler diets supplemented with enzymes increased significantly the total proteins and globulin levels and reducing the cholesterol level in serum, which might supported by the enhancement of some immune organs (spleen and bursa).
Implementation and Statistical Analysis of Filled and Unfilled SRN Using SVM Tools

-In power sector, with increase in voltage level in transmission, there is a need for new insulating material with better electrical and mechanical performance at affordable cost. But the major problem posed in using high voltages is different from those encountered at low voltages. Some major problems in high voltage are transients, interruptions, sag, swell, voltage fluctuation, corona, frequency variation. One major problem under wet conditions, insulators are vulnerable to corona discharges. If the corona is allowed to occur continuously it will collapse the system. This paper mainly concentrated on analysis of aging phenomenon of unfilled and filled silicone rubber Nano composites materials. An AC voltage of 8kv is applied continuously for the required duration of about 30 hours of aging. Corona discharge will be generated by needle plate electrode enclosed in a large chamber. Support Vector Machine (SVM) is used to analyze the performance of the samples. This paper is concentrated on review the performance of the nanocomposites material which is much better than the unfilled silicone rubber materials. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 02-04-2018 Date of acceptance: 17-04-2018 -------------------------------------------------------------------------------------------------------------------------------------
Vascular endothelial growth factor as a potential prognostic factor for T3N0 rectal cancer Vaskularni endotelni faktor rasta kao potencijalni prognostički faktor kod T3N0 stadijuma karcinoma rektuma

Background/Aim. Rectal cancer still presents a major health problem. Although a surgery is the mainstay of the rectal cancer treatment, there is now widespread agreement that combined modality therapy is often indicated. Around 20% of T3N0 rectal cancer patients develop distant or local relapse of the disease. There is a need for prognostic biomarkers that could help us determine the subgroup of patients with a high risk for recurrence. The aim of this study was to determine the prognostic potential of vascular endothelial growth factor (VEGF) in patients with T3N0 rectal carcinoma. Methods. This retrospective study included 163 selected T3N0 rectal cancer patients, operated on the Department for Colorectal Surgery of the Clinic for Digestive Surger (First Surgical Clinic), Clinical Centre of Serbia, Belgrade. VEGF expression was immunohistochemically assessed. Oncological outcome was analyzed using data from prospectively designed data base. Parameters of interest were: distant metastases, the disease free and overall survival. Survival and time to recurrence were evaluated using Kaplan Meier`s method and the factors were compared with the long-rank test. Results. There were 102 men and 61 women. The median age was 62 years (age range, 31–88 years). Median follow-up interval was 81 months (range, 4– 177 months). During the follow-up period 6 patients developed local recurrence, in 31 patients distant metastases occurred. Three factors were found to be associated with distant metastases: VEGF expression, mucinous adenocarcinoma and tumor differentiation (p < 0.05). In patients with positive VEGF expression, the disease free survival and overall survival were significantly worse than in negative ones (65% and 59%, respectively) (log-rank test, p < 0.05). Conclusion. High VEGF expression in T3N0 rectal carcinomas together with some standard histopathological tumor features can give us enough information to identify subgroup of patients with high risk for recurrence and poorer prognosis.
Thermodynamic investigations on thermoelectric coolers: a review

In today’s era, power generation and devices working low power output are the main point of attraction all over the world. In this context, thermoelectric devices (TEs) possess large number of advantages like low power operation, no mobile parts, no hazardous operating media, ruggedness and minimum operating maintenance requirements. That is why these devices are highly applicable in number of emerging fields like biomedical, commercial, defense, aeronautics etc. They work on the principle of direct conversion of heat energy into electrical power output and vice-versa following Seebeck and Peltier effects. They can also be integrated/cascaded with other energy generation routes like Solar/PV, Solar/Thermal or high temperature exhaust from various industrial processes. In present work, singleand 2-stage thermoelectric coolers are thermodynamically reviewed in view of 1 st /2 nd law of thermodynamics. It is found that the thermoelectric coolers made up of semiconductor p-type and n-type modules are highly efficient at low power output in comparison to the conventional cooling options. The variations in the coefficient of performance (COP) of these devices is investigated and presented with respect to different number of thermoelectric modules for various working electrical current values. It is also found that effective balance between various performing variables is very much required for improving the operating parameters of these devices.

Evaluation of the Efficacy of Leukocyte-Platelet Rich Fibrin versus Platelet Rich Fibrin Matrix on Bone Healing

Objective: The aim of this study was to compare the efficacy of leukocyte-platelet-rich fibrin (L-PRF) and platelet-rich fibrin matrix (PRFM) on bone healing. Methods: Eight rabbits were included in this controlled, prospective, blinded study. Defects with a diameter of 3 mm and 2 mm depth were created in the bone of both tibias, filled with L-PRF (group II), PRFM (group III) or left empty (group I). The bone mineral density (BMD) was measured by dual energy absorptiometry (DXA) and histological examination was performed on the 10th and 21st days. Results: According to Emery’s histopathological healing criteria, control group (group I) revealed score 0 and score 3 at 10 and 21 days respectively. Group II showed score 2 and score 5 at 10 and 21 days respectively. On the other side group III treated by PRFM showed score 3 and score 7 at 10 and 21 days respectively. Conclusion: Both L-PRF and PRFM showed increased bone formation in surgically created bone defects in rabbits, however, the effect of PRFM was more pronounced. The use of PRFM and L-PRF may contribute to the success of bone regeneration.
On privacy of dynamical aystems: an optimal probabilistic mapping approach

We address the problem of maximizing privacy of stochastic dynamical systems whose state information is released through quantized sensor data. In particular, we consider the setting where information about the system state is obtained using noisy sensor measurements. This data is quantized and transmitted to a remote station through a public/unsecured communication network. We aim at keeping the state of the system private; however, because the network is not secure, adversaries might have access to sensor data, which can be used to estimate the system state. To prevent such adversaries from obtaining an accurate state estimate, before transmission, we randomize quantized sensor data using additive random vectors, and send the corrupted data to the remote station instead. We design the joint probability distribution of these additive vectors (over a time window) to minimize the mutual information (our privacy metric) between some linear function of the system state (a desired private output) and the randomized sensor data for a desired level of distortion--how different quantized sensor measurements and distorted data are allowed to be. We pose the problem of synthesizing the joint probability distribution of the additive vectors as a convex program subject to linear constraints. Simulation experiments are presented to illustrate our privacy scheme.

A Study on Constant Voltage Design for Single-Frequency Two-Stream Contactless Power Transfer with Cross-Coupling

This paper proposes a voltage stabilization scheme for feeding constant voltage to receiver in single-frequency two-stream contactless power transmission under the presence of cross coupling among couplers. We have demonstrated that the constant voltage could be provided to receiver load with mitigating cross coupling by inserting a compensation block followed couplers at receiver. In order to obtain more stable voltage rather than previous scheme, dividing a compensation block into two parts is newly proposed. A part of block is placed in the vicinity of transmitter couplers. Computer simulation including electromagnetic and electric circuit was conducted for comparing the performance.

Precursors for enabling higher-efficiency silicon wafer solar cells

The manufacturers of silicon wafer solar cells are constantly looking into cost-effective ways to increase the efficiency of their solar cells. Most of these enhancements result from incremental improvements and can be achieved by optimizing existing processes. However, it is widely recognized that in order to further improve the silicon wafer solar cell efficiency, new solar cell architectures are required. This will in turn require new manufacturing processes, which will typically involve new production equipment and consumables. New consumables can play an important role in the applicability or success of a new process step; in this paper a specific focus will be on the precursors used for the deposition of surface passivation films, such as silicon nitride and aluminium oxide. Cell technology Material Most common precursors Passivated emitter and rear contact (PERC), AlOx TMA or Al local back-surface field (Al-LBSF) solar cells SiOx SiH4 and N2O or OCTMS

In this article, mixed finite volume element (MFVE) methods are proposed for solving the numerical solution of Burgers’ equation. By introducing a transfer operator, semidiscrete and fully discrete MFVE schemes are constructed. The existence, uniqueness, and stability analyses for semidiscrete and fully discrete MFVE schemes are given in detail. The optimal a priori error estimates for the unknown and auxiliary variables in the norm are derived by using the stability results. Finally, numerical results are given to verify the feasibility and effectiveness.
Identification and Characterization of the Epidemiological Risk Factors of Type 2 Diabetes Mellitus

No Conflict of Interest: Declared Diabetes is a key health concern all over the world with a vast number of people being freshly diagnosed each day. This research work evaluates the epidemiological influence, risk factors and hypertension as a complication associated with type 2 diabetes mellitus, through a bio-statistical retrospective of analysis. The study found that rural residency, sedentary lifestyle, low income and expense, lower socioeconomic status, lower levels of physical exercises are related to type 2 diabetes mellitus; among the relatively newly diagnosed patients. However, BMI, cholesterol levels, resting heart rate, serum creatinine and serum ALT seemed to be normal among the majority of diabetic patients in the study. The female diabetic patients were found to be more overweight and obese in comparison. Genetic susceptibility or hereditary association was not found to be a predominant risk factor for type 2 diabetes mellitus and hypertension. Lower middle-class rural people, with much lower levels of literacy and lower family expenses having type 2 diabetes, were seen to be more prone to development of hypertension as compared to the urban people. There was no connection found between hypertension and cholesterol levels in hypertensive diabetic patients. The analysis also showed that type 2 diabetic patients are the most disposed to develop hypertension at the age range of 41-50 as a complication. There is also a moderate risk of development of hypertension in 51-60 years of age in type 2 diabetic patients.
30 dB microstrip coupler with high directivity

Due to inhomogeneous structure of a microstrip directional couplers, i.e. partly dielectric substrate, partly air, they mostly present property of poor directivity and low coupling level. High directivity is achieved by a capacitive compensation by gap coupling of open stub formed in sub-coupled line. Neverthless, these couplers have advantage of easy fabrication, lightweight and incorporation with other microwave devices, and is validated via design using Sonnet software. The main goal was to obtain coupling around -30 dB, meaning that almost all power is passed to the output, with a wide band, from around 3.5GHz to nearly 9GHz. Desired values have been obtained, including isolation and input match reaching -70 dB.
Emerging Multi-Port Electrical Machines and Systems : Past Developments , Current Challenges and Future Prospects

Distinct from the conventional machines with only one electrical and one mechanical port, electrical machines featuring multiple electrical/mechanical ports (the so-called multi-port electrical machines) provide a compact, flexible, and highly-efficient manner to convert and/or transfer energies among different ports. This paper attempts to make a comprehensive overview of existing multi-port topologies, from fundamental characteristics to advanced modeling, analysis, and control, with particular emphasis on the extensively investigated brushless doubly-fed machines for highly-reliable wind turbines and power split devices for hybrid electric vehicles. A qualitative review approach is mainly adopted but strong efforts are also made to quantitatively highlight the electromagnetic and control performance. Research challenges are identified and future trends are discussed.
Effect of Copper on Hematological, Biochemical Changes and Reproductive Hormones of the Nile tilapia Oreochromis niloticus

The effect of copper concentrations on alterations in hematological and biochemical parameters as well as reproductive hormones of the Nile tilapia Oreochromis niloticus was investigated. The copper sulfate at sub-chronic concentrations 25, 50 and 75 µg/L on Oreochromis niloticus for 90 days of exposure. Significant changes (P ˂ 0.05) in almost all hematological aspects were found in the all groups exposed to different concentrations of copper 25, 50 and 75 µg/L for 90 days. Biochemical analysis revealed various significant (P ˂ 0.05) differences among the all groups that exposed to 25, 50 and 75 µg/L of copper for 90 days of exposure. There was a significant difference in the copper concentrations in the tissues (P ˂ 0.05) among all treated groups; in liver, gills and kidney. Glucose and cortisol in fish plasma increased significantly, while total protein and total lipids decreased significantly due to copper stress. The obtained results showed also that copper stress was harmful to the fish liver and kidney, where plasma aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, uric acid, and creatinine values were significantly increased with the increasing exposure of copper on Oreochromis niloticus for 90 days compared to the control one. Plasma follicular stimulating hormones (FSH), 17s estradiol (E2) and testosterone (T) were decreased significantly in fish with the increasing exposure of copper concentrations. Among antioxidative enzymes, significant changes were revealed mainly in plasma ceruplasmin and glutathione reductase and glutathione peroxidase activity in liver and gills (P ˂ 0.05. The results demonstrate the deleterious influence of copper on Oreochromis niloticus, even at low doses. So, it is recommended to not use copper too much during treatment of the water that used in growing the fish.
