A Review of Tactile Information: Perception and Action Through Touch

Tactile sensing is a key sensor modality for robots interacting with their surroundings. These sensors provide a rich and diverse set of data signals that contain detailed information collected from contacts between the robot and its environment. The data are however not limited to individual contacts and can be used to extract a wide range of information about the objects in the environment as well as the actions of the robot during the interactions. In this article, we provide an overview of tactile information and its applications in robotics. We present a hierarchy consisting of raw, contact, object, and action levels to structure the tactile information, with higher-level information often building upon lower-level information. We discuss different types of information that can be extracted at each level of the hierarchy. The article also includes an overview of different types of robot applications and the types of tactile information that they employ. Finally we end the article with a discussion for future tactile applications which are still beyond the current capabilities of robots.
Folded Transmitarray Antenna With Circular Polarization Based on Metasurface

We propose a low-profile broadband planar circularly polarized folded transmitarray antenna (CPFTA) based on well-designed top and bottom metasurfaces (MSs). The top MS is employed to reflect the <inline-formula> <tex-math notation="LaTeX">$x$ </tex-math></inline-formula>-polarized wave as a ground and, at the same time, to convert the <inline-formula> <tex-math notation="LaTeX">$y$ </tex-math></inline-formula>-polarized wave into circularly polarized waves with arbitrary phase shifts in the operation band. A bottom MS is applied to reflect the incident wave and twist its polarization by 90°. The whole CPFTA, including the feeding source of microstrip antenna, and the top and bottom MSs can be fully integrated and fabricated using low-cost printed circuit board technology. Both simulated and measured results demonstrate significant advantages of the proposed antenna, including broad bandwidth, high gain, lower profile, planar geometry, and easy integration. The fabricated sample shows 3 dB axial ratio (AR) bandwidth of 23.2%, 3 dBi gain bandwidth of 11.6%, and the maximum gain of 22.8 dBi at 10.3 GHz with the antenna efficiency of 21.8%. The proposed CPFTA is promising for applications in satellite communications with circularly polarized antennas.
LSTM-Based Forecasting for Urban Construction Waste Generation

Accurate forecasts of construction waste are important for recycling the waste and formulating relevant governmental policies. Deficiencies in reliable forecasting methods and historical data hinder the prediction of this waste in long- or short-term planning. To effectively forecast construction waste, a time-series forecasting method is proposed in this study, based on a three-layer long short-term memory (LSTM) network and univariate time-series data with limited sample points. This method involves network structure design and implementation algorithms for network training and the forecasting process. Numerical experiments were performed with statistical construction waste data for Shanghai and Hong Kong. Compared with other time-series forecasting models such as ridge regression (RR), support vector regression (SVR), and back-propagation neural networks (BPNN), this paper demonstrates that the proposed LSTM-based forecasting model is effective and accurate in predicting construction waste generation.
Genotyping of Advanced Backcross Progenies Derived From Tellahamsa and MTU1010 Rice Varieties for BB and Blast Resistance

Rice is a monocotyledonous angiosperm. It belongs to the genus Oryza, which contains 20 wild and two cultivated species. Oryza sativa cultivated in South Asia and Japan, while Oryza glaberrima cultivated in West Africa (Watanabe, 1976). The production of rice was 104.32 million tonnes from an area of 43.39 million hectares in India during 2015-16. Total production of rice by May 9, 2017 was 109.15 million tons in India (Ministry of Agriculture and Farmers Welfare, 2017). In India, 65 % of the population depends on rice as their staple food and the country is a huge contributor to the global rice production. However, biotic and abiotic stresses are causing huge yield losses. Bacterial blight (BB) and rice blast are the two most important diseases causing significant yield loss in rice, and they are endemic to several rice growing states of India. In Telangana and Andhra Pradesh states, the yield loss is very severe due to BB and blast. In order to address the above said issues, the efforts have been made by Institute of Biotechnology, Rajendranagar, Hyderabad, and developed MTU1010 and Tellahamsa introgression lines with bacterial blight (xa13 and Xa21) and blast (Pi54 and Pi1) resistance genes by backcrossing with donor parents. GPP2 was used as a donor for bacterial blight resistance genes (xa13 and Xa21), while NLR145 (Swarnamukhi) was used as donor for blast resistance genes (Pi54 and Pi1). Genotyping of these advanced backcross progenies of MTU1010 (BC4F5) and Tellahamsa (BC3F4) was carried out to check the uniformity of plants with in the progeny in homozygous condition for target genes. DNA bulking method was used to reduce the time, resources and number of samples from 3465 to 99 for DNA isolation without compromising the quality of DNA. Genotyping was carried out in 29 advanced backcross progenies (BC3F4, BC4F5) for the presence of four target genes viz., xa13, Xa21, Pi54 and Pi1 by using gene specific / linked PCR based molecular markers viz., xa13-prom, pTA248, Pi54 MAS and RM224, respectively. The bulk sample analysis of 29 progenies exhibited uniformity for the target genes. K e y w o r d s
A Parameter-Independent Optimal Field-Weakening Control Strategy of IPMSM for Electric Vehicles Over Full Speed Range

The rest if this article proposes a field-weakening control strategy along with two characteristic curves of IPMSM under electric vehicle driving conditions, where the operation speed, load torque, and target torque change rapidly and continuously. Two characteristic curves, the maximum torque curve, and the switching torque curve are introduced to obtain a strategy that can generate the optimal operation point with minimum stator current at any machine speed. The reference current of the optimal operation points can be derived from both calculation method and conventional calibration method. However, sometimes it is difficult to get solutions directly by the calculation method, not to mention it relies on precise motor parameters that vary with the temperature and magnetic saturation. Additionally, conventional calibration method is really a time-consuming process. In this article, a much simpler approach to obtain reference current based on polynomial fitting is presented, which has a great performance on fitting precision and much less workload with only one additional operation point to be calibrated except for the two characteristic curves. With this fitting method, the reference current generation procedure becomes completely parameter independent. The proposed strategy is demonstrated through simulations and test bench results.
Prenatal treatment with metronidazole induces cerebellar folia alteration in guinea pig fetuses

The most sensitive period in brain development is during prenatal life. The use of antibiotics in pregnancy is still controversial. Recent studies revealed the high neurotoxic potential of the antibiotic and antiprotozoal medication, metronidazole. However, there are insufficient data from animal studies about prenatal treatment effects. We investigated the effect of prenatal treatment with metronidazole on cerebellar development in guinea pigs. Treatment with metronidazole was performed from the 42nd to the 49th day of gestation. On the 50th day of pregnancy, all dams were killed, and the cerebella of the fetuses were analyzed. Gross cerebellar changes characterized by malposition of the folia with partial atrophy were found in 12 of 19 fetuses in the experimental group, but in none of 20 control fetuses that received saline. The most affected were folia VII with depletion of the areal fraction of the external granular layer, molecular layer and the internal granular layer. Purkinje cells displayed cell distortion with loss of normal dendritic polarity. The investigation revealed cell depletion, with a disturbance of the cytoarchitectonic of the cerebellar cortex and folia alteration.
A conserved motif of Porphyromonas Type IX secretion effectors C-terminal secretion signal specifies interactions with the PorKLMN core complex

The Type IX secretion system (T9SS) is a versatile protein transport apparatus restricted to the Bacteroidetes phylum. This multiprotein complex enables secretion of a wide range of effectors, such as protein toxins, filamentous adhesins, enzymes or S-layer subunits. Once translocated in the periplasm through the Sec pathway, recognition and secretion of these cargo proteins rely on a conserved C-terminal domain referred as CTD. However, the precise route followed by the CTD substrates from the periplasm to the cell exterior is yet to be determined. Here we define the interaction network of five different CTDs from the oral pathogen Porphyromonas gingivalis with the PorKLMN T9SS trans-envelope complex. We show that these five CTDs interact with the inner membrane-anchored PorM and the PorN periplasmic proteins. We further determine the contribution of the PorM IgG-like periplasmic domains and CTD conserved motifs for PorM-CTD complex formation. These results showed that all five CTDs interact with the core complex in a similar manner, suggesting a conserved mechanism of substrate selection in the periplasm. Our results thus establish a first model of the path followed by the CTD substrates through the T9SS.
Edaphic Drivers of Community Structure and Composition in a Mixed Ombrophilous Forest

This study sought to assess the variation in species composition and community structure considering soil characteristics. Based on physical and chemical analyses of soil, we selected four sites for vegetation sampling: Haplic Cambisol (P1), Regolithic Neosol (P2), Latosol Bruno (P3) and Humic Cambisol (P4). In each site, we sampled all arboreal individuals with DBH 4.8 cm. Sites were distinguished by species with different values of importance and indicator index (indVal). Sites were clearly separated in biplots generated by canonical ordination (RDA), which indicated that the distribution of species correlates with acidity, Al+, C and P concentrations, CEC, pH, base saturation, drainage, and pedological unit. Our results show that local scale variation in soil attributes influences tree species composition and community structure, and, thus, should be considered for understanding the distribution, occupation, and response of tree species in remnants of Mixed Ombrophilous Forest.
Sensory and nutritional evaluation of chapatti prepared from composite flours of coarse cereals and tulsi

In the present study six types of chapattis were prepared from composite flours of coarse cereals with and without tulsi leaves powder. The chapatti prepared from composite flours of blanched pearl millet: sorghum: dehusked oat: germinated chickpea in ratios of 60:10:10:20 (Type-II) and blanched pearl millet: sorghum: dehusked oat: germinated chickpea: tulsi leaves in ratios of 60:10:10:15:5 (Type-V) were organoleptically most acceptable and fell in the category of ‘liked moderately’. Nutritional value of chapatti prepared from composite flours of coarse cereals with and without tulsi leaves was significantly higher than control wheat chapatti. The crude protein content of composite flour based chapatti (11.25%) followed by composite flour tulsi chapatti (11.18%) was significantly (P
Control of Sewer Flow using a Buffer Tank

Flow variations of the inlet to a wastewater treatment plant (WWTP) are problematic due to the biological purification process. A way to reduce variations from industrial areas is to insert a buffer tank. Traditionally the only on-line measurement is the inlet flow to the wastewater treatment plant and reliable measurements in the system are difficult to establish. A control scheme using only one on-line measured variable is shown to be able to give considerable reduction in the flow variations. To implement the control scheme two models are introduced. A linear model (delay model) from the buffer tank to the wastewater treatment plant and an autonomous model describing the daily variations in the household sewer flow. A Model Predictive Controller has been designed and tested in a laboratory set-up with good results.
Impact Shock Sensitivity of a TATB Based Explosive Relevant to Specific Heat Properties

Abstract : This report is a supplementary follow-on to U.S. Army Missile Command (MICOM) TR-RD-SS-95-2, and Aviation and Missile Command (AMCOM) TR-RD-SS-99-8 that related plane impact shock sensitivity of CHNO energetic material to specific heat (Cp) per average atom magnitude and reactive temperature (TR) conditions. Specifically, plane shock energy input equal to the thermal vibratory energy increment (this is the area under the Cp versus T data curve between experimental temperature, (T sub EXP), conditions and reactive temperature conditions) is sufficient to cause shock induced reactions, up to and including detonation in energetic materials. This is demonstrated at four different test temperatures ((T SUB EXP)) for PBX-9502.
Design, Analysis, and Implementation of Wireless Shaded-Pole Induction Motors

In this article, a wireless shaded-pole induction motor (SPIM) is proposed and implemented, which artfully integrates wireless power transfer into a single-phase SPIM to achieve the first wireless ac motor. Prominently, there is no controller at the SPIM side, as the controlling process is fully conducted at the transmitter side. Meanwhile, there is no need to specially design the motor, as all existing SPIMs can readily be used. The key is to propose a self-driving circuit in the receiver, which can provide variable-voltage variable-frequency control of the SPIM. As a result, the proposed wireless SPIM takes the definite advantages of electrocution-free and totally sealable. A 110 W prototype has been built for experimental verification. It can offer wireless speed control from 486 to 1330 r/min with the transfer distance of 30 mm and the transmission efficiency of 86.2%.
Influence of childhood overweight and obesity on foot and lower limb pain in a population of primary school children

Introduction: In childhood, juvenile obesity affects the functional characteristics of the lower limb, predisposing children to pain, discomfort and musculoskeletal comorbidities. This cross-sectional descriptive study analyses the relationship between childhood overweight/obesity and foot/lower limb pain in a population of primary school children. Material and methods: The study population consisted of 150 children aged 9–12 years recruited at a primary school in Malaga (Spain). None had pathologic feet. Anthropometric and demographic data were compiled by questionnaire and by personal interview. Among other variables, the foot posture index was calculated and knee alignment was measured. In the statistical analysis, the dependent variables considered were foot and lower limb pain, and the predictor variables were age, sex, body mass index, sports activity, foot posture index and knee alignment. A descriptive analysis of these variables was performed, together with an association analysis (using the c2 test) and a multivariate analysis (using binary logistic regression). Results: In the study sample, 47.3% were girls, 15.3% were overweight and 12.7% obese. The overall prevalence of foot pain was 10.7% and that of lower limb pain, 27.3%. Of the study variables analyzed, the only ones significantly related to both foot pain and lower limb pain were overweight and obesity. Conclusions: Overweight and obesity are the main factors related to pain in the feet and lower limbs in primary school children.
Anti-tuberculosis Compounds from two Bolivian Medicinal Plants, Senecio Mathewsii and Usnea Florida

Bioassay-directed fractionation of the organic extract of Senecio mathewsii gave four compounds with anti-TB activity: werneria chromene (1), capillarol (2), werneria chromanone (3) and plicatin B (4). All of these are new to the genus Senecio and one of these, werneria chromanone (3), was isolated from a natural source for the first time. With the aid of 2D NMR, revised (1) or new (2–4) spectral assignments were made. Similarly, the major anti-TB activity of Usnea florida was shown to be solely due to usnic acid.
DNA unwinding by Viral Protein R Initializes Complicated Cellular Responses in HIV-1 Infection: Defining the Viper’s First Bite

Vpr, an accessory gene of human immunodeficiency virus (HIV) type1 that encodes a virion-associated protein, induces multiple cellular responses, e.g. transcriptional regulation, chromatin modulation and the DNA damage response with cell-cycle checkpoint activation. Vpr may promote HIV-1 infection of quiescent cells, including resting macrophages, but it remained elusive how Vpr contributes to viral infection into these cells. With the object of clarifying the role of Vpr, we first summarize the pleiotropic function of Vpr in the HIV-1 life cycle and subsequently the recently identified mode of Vpr-induced DNA damage triggered by unwinding of DNA in association with viral DNA integration. Finally, we discuss the role of Vpr in HIV-associated diseases, which are important issues for HIV-1–infected patients in the post-antiretroviral therapy era.

The in vitro antioxidant properties ofMuscari comosumbulbs and their inhibitory activity on enzymes involved in inflammation, post-prandial hyperglycemia, and cognitive/neuromuscular functions

Extracts of Muscari comosum bulbs, a traditional Mediterranean food, were analyzed by high performance liquid chromatography for polyphenol content and tested for their activity on free‐radicals and enzymes that might be involved in human health. The extracts revealed the presence of phenolic acids and flavonoids with antioxidant and anti‐inflammatory properties. Antioxidant activity was determined by evaluating the radical scavenging activity toward 2,2‐diphenyl‐1‐picrylhydraziyl (DPPH˙), nitric oxide (˙NO), and superoxide (O₂˙⁻₎, whereas the anti‐inflammatory activity was determined by zymography by evaluating the in‐gel inhibition of MMP‐9 and MMP‐2, two pro‐inflammatory gelatinases. Anti‐glycemic activity was determined by measuring the inhibition of α‐amylase and α‐glucosidase, two enzymes involved in post‐prandial hyperglycemia. Finally, M. comosum extracts were found to inhibit the enzyme acetylcholine esterase. The resulting increase of acetylcholine availability might improve cognitive functions and neuromuscular transmission. Our laboratory findings substantiate and extend previous results, but the clinical value of M. comosum properties needs to be further evaluated. PRACTICAL APPLICATIONS: Muscari comosum bulbs are mostly used in a few Mediterranean countries and in particular in Southern Italy, where they are commonly known as “lampascioni” or “cipollacci. ” The most popular recipe in traditional gastronomy. consists in boiling the cleaned bulbs and keep them in olive oil. The present study shows that M. comosum bulbs have a strong antioxidant and anti‐inflammatory activity in vitro, and inhibit specific enzymes involved in hyperglycemia or cholinergic neurotransmission. The above properties might be useful in diabetic individuals to reduce post‐prandial hyperglycemia and might improve acetylcholine transmission and therefore cognitive and neuromuscular functions.
