Automatic Error Correction of Rainfall-Runoff models in Flood Forecasting Systems

Physical modelling of the dynamics of a catchment area produces simulation models with a limited forecasting accuracy for the discharge of rivers. The discrepancies between the simulation model and the actually observed past discharges can be used as additional information for error correction. With a time series model of the recent past error signal, an improved discharge forecast can be made for the next few days. The best type and order of the time series model can be selected automatically. Adaptive modelling in data assimilation calculates updates of the time series model estimated from the error data of only the last few weeks. The use of variable updated models has advantages in periods with the largest discharges, which are most important in flood forecasting
Characteristic Mode Assisted Placement of Antennas for the Isolation Enhancement

In this letter, the isolation between onboard antennas is investigated using characteristic mode analysis, which provides an intuitive insight for the antenna placement on large platforms. An analytical expression of the relationship between the platform modal excitation coefficient and the platform modal charge is derived under the condition of a coaxial feeding mechanism. It is revealed that the deployment position that leads to a maximum isolation is indicated by the platform modal charge. Based on this finding, a simple and efficient method for antenna placement on aircraft-like platforms is developed to enhance the isolation. Two examples with vertically polarized blade antennas are presented, in which two or three blade antennas can be deployed on the platforms. Both the numerical and experimental results show that the isolation is increased remarkably by the proposed method.

Osteomyelitis as a possible cause of rootless Turner’s tooth: a case report

Tooth extraction is an ordinary type of treatment that is performed routinely at dental treatment units. The procedure of dental extraction may be accomplished without any collateral complications or, on the other hand, be followed by problematic consequences. Many factors control the outcome of the extraction procedure, whether it is conducted smoothly or in a vigorous way. In the current study, we present a case of an ordinary extraction of a primary tooth revealed a more advanced infection, i.e. chronic suppurative osteomyelitis, which might have caused a cease of the root formation and hypoplasia of the crown of the succedaneous tooth.
Fisher memory of linear Wigner echo state networks

We study asymptotic properties of Fisher memory of linear Echo State Networks with randomized reservoir coupling prescribed by the class of Wigner matrices. Several properties of Fisher memory normalized per state space dimension are derived. In particular, we show that as the system size grows, the contribution of self-coupling of self-loops on reservoir units to the Fisher memory is negligible. Furthermore, we prove that the maximal Fisher memory is achieved when the input-to-state coupling is colinear with the dominant eigenvector of the state space coupling matrix. Finally, we show that when the input-to-state coupling is colinear with the sum of eigenvectors of the state space coupling, the expected normalized memory is four time smaller than the maximal memory value.
Multilevel haar wavelet transform and histogram based relevant image retrieval system

This paper presents the relevant image retrieval system, using feature like color and texture, called Multilevel Haar Wavelet Transform and Color Histogram based Relevant Image Retrieval. The texture feature is extracted through multilevel haar wavelet transformation and the color feature is extracted through the color histogram and the combination of these features is robust to scaling and translation of objects in an image. The proposed system has demonstrated a promising and faster retrieval method on an image database containing general-purpose color images. The performance has been evaluated by comparing with the existing systems in the literature. The expansion of content based image retrieval technique can be found in a number of different domains. Content Based Image Retrieval is putting into practice for the image retrieval problem that is the problem of searching for digital images in large databases.
Maternal Influenza: Infection, Vaccination, and Compelling Questions

Influenza presents a significant risk for increased morbidity and mortality to pregnant women and infants based on evidence from previous influenza pandemics, seasonal epidemics, and the recent H1N1 pandemic. Since 2004, influenza vaccine has been recommended for pregnant women during any trimester of pregnancy to reduce this risk. This chapter presents an overview of influenza risks associated with pregnancy as well as a review of our current understanding of vaccine effectiveness in pregnant women, neonates, and young infants. In addition, some of the current compelling questions related to influenza risk and prevention across all trimesters of pregnancy are explored.
The Effect of Upper-Limb Dominance on Forearm Sweating Patterns in Children and Adolescents with Cerebral Palsy

The aim of this study was to examine the effect of upper-limb dominance on the forearm sweating pattern in cerebral palsy (CP). Eight boys with CP (13.1 ± 3.1 years) performed three 10-min bouts of an arm-cranking exercise at 35°C, 50% relative humidity. After the third bout, the sweat drops on both forearms were photographed. Sweat gland density (PD) and the average sweat drop area (DA) were determined. PD was significantly higher (p < .05), whereas DA was significantly lower (p < .05) on the nondominant compared with the dominant forearm. The sweating pattern in spastic CP is influenced by upper-limb dominance.
Land Cover Classification and Change Analysis in the Horqin Sandy Land From 1975 to 2007

Observations over the last three decades show that desertification poses a serious threat to the livelihood and productivity of inhabitants of the Horqin Sandy Land region of China. We evaluated the dynamics and trends of changes of land cover in the Horqin Sandy Land by using Landsat archive images from 1975, 1987, 1999, and 2007. We applied two supervised classification methods, the self-organizing map neural network method and the subspace method. Our analyses revealed significant changes to land cover over the period 1975-2007. The area of cropland doubled over the last three decades. This expansion was accompanied by large increases in water consumption and considerable loss of areas of grassland and woodland. Many lakes and rivers shrank rapidly or disappeared in this region between 1975 and 2007. The sandy area expanded rapidly from 1975 to 1987 but gradually slowed thereafter.

Dual-Function Metal–Insulator–Metal Plasmonic Optical Filter

We suggest a dual-function plasmonic optical filter based on a metal-insulator- metal waveguide that has a deep subwavelength air gap 10 nm in thickness and a waveguide width of 350 nm. Because the dispersion curves of even and odd waveguide modes have different dependences on the waveguide width, and only the odd mode has a cutoff frequency, the proposed structure can have dual functionality, acting as a resonant tunneling filter for odd modes and a simple waveguide for even modes.
A circular equilibrium model for local gyrokinetic simulations of ion temperature gradient fluctuations in reversed field pinches

A simple large-aspect-ratio (R0/r) circular equilibrium model is developed for low-beta reversed field pinch (RFP) geometry. The model is suitable for treating small scale instability and turbulent transport driven by ion temperature gradient (ITG) and related electron drift modes in gyrokinetic simulations. The equilibrium model is an RFP generalization of the common tokamak s-α model to small safety factor (q), where the poloidal field dominates the toroidal field. The model accommodates the RFP toroidal field reversal (where q vanishes) by generalizing the cylindrical force-free Bessel function model (BFM) [J. B. Taylor, Phys. Rev. Lett. 33, 1139 (1974)] to toroidal geometry. The global equilibrium can be described in terms of the RFP field reversal and pinch parameters [F,Θ]. This new toroidal Bessel function model (TBFM) has been incorporated into the gyrokinetic code GYRO [J. Candy and R. E. Waltz, J.Comput. Phys. 186, 545 (2003)] and used here to explore local electrostatic ITG adiabatic electron i.
Morphological changes in placentas of normal and high risk pregnancies-2 years study in MGM hospital

Background: Placenta-related disorders of pregnancy are almost unique to human species. These disorders, which affect around a third of pregnancies, primarily include miscarriage and preeclampsia. Aim and objectives: The aim of the present study was to examine the morphological changes in placentas of normal and high risk pregnancies, and to evaluate the fetal outcome in these cases, which in turn will improve the quality of placental diagnosis. The objectives were to know the extent of the gross and microscopic placental changes that occur in normal pregnancies and to study the placentas of high risk pregnancies. Materials and methods: A study of 132 placentas in normal and high risk pregnancies was conducted in the Department of Pathology, Kakatiya Medical College, MGM Hospital, Warangal, from 1 st September 2014 to 31 st August 2016. The materials included in this study were placentas from thirty females with normal pregnancies (controls) and one hundred thirteen with high risk pregnancies (cases) comprising anemia (27), pregnancy-induced hypertension (38), intrauterine growth retardation (15), diabetes mellitus (13), and twins (9). Results: In high risk cases, women in the age group 21-25 years were 66.6% in anemia, 60.5% in PIH, and 60% in IUGR 69.2% in diabetes mellitus, and 33.3% in twin pregnancies. Only a few cases Samala Raghuram Mohan, Jyosna, Sandhya Anil, S. Chandra Sekhar. Morphological changes in placentas of normal and high risk pregnancies 2 years study in MGM hospital. IAIM, 2017; 4(5): 61-78. Page 62 were seen in the age group of 26-30 in both controls and cases. Seventy percent of the controls belonged to primigravida and 30% were multiparous women. In high risk cases, 66.6% were primigravida and 33.3% multipara. Majority of the multiparous mothers were seen in anemia constituting 48.1%. High risk cases exhibited exaggerated changes, except for calcification, which was seen equally in both the groups. Infarction was seen in 50% cases of PIH. Single case of retroplacental hematoma was also observed in PIH. Subchorionic fibrinoid was seen in 53.4% of IUGR placentas. Maternal floor infarction was seen in 4 cases of PIH and 3 cases of IUGR placentas. Subchorionic hematoma was seen in 1 case of IUGR placenta. IUGR placentas were small in size and weight for the gestational age and twin placentas were of diamniotic dichorionic type. The most prominent microscopic features were syncytiotrophoblastic knot formation and calcification. The high risk groups were showing prominent infarcts, fibrinoid necrosis, and stromal fibrosis more than those of control group. Conclusion: The present study has highlighted the importance of examination of placenta in normal as well as high risk pregnancies. The placental changes are essential to correlate the fetal outcome, as it provides the information for the cause of death. Hence, it has an effective role in planning prenatal monitoring of a future pregnancy.
Fully Integratable Class-AB Rear-End with Smart Quiescent Current Control for a General-Purpose Hearing Aid Chip

In this paper, the core of the rear-end of an universally applicable analog hearing aid chip is described. It contains, apart from some subcircuits, a current-level Class-AB controlled preamplifier with three independent gain controls and a novel half-switching bridged final amplifier for various hearing aid receivers from low-power up to medium-power. To minimize supply current, the quiescent current of the amplifier string is optimized at any value of the input current and the controlled gain by a translinear quiescent current processor. Chip area in a 2.5-¿m BiCMOS process amounts to 2.6 mm2. Measured THD remains below 2% in all cases (1kHz). The bandwidth is ≫12kHz. All circuits operate correctly with a battery voltage down to 1.05V. Total current drain (without input signal) varies between 140¿A and 425¿A.
Atomic scale control of hexaphenyl molecules manipulation along functionalized ultra-thin insulating layer on the Si(1 0 0) surface at low temperature (9 K)

Ultra-thin CaF2 layers are grown on the Si(1 0 0) surface by using a Knudsen cell evaporator. These epitaxial structures are studied with a low temperature (9 K) scanning tunneling microscope and used to electronically decouple hexaphenyl molecules from the Si surface. We show that the ultra-thin CaF2 layers exhibit stripe structures oriented perpendicularly to the silicon dimer rows and have a surface gap of 3.8 eV. The ultra-thin semi-insulating layers are also shown to be functionalized, since 80% of the hexaphenyl molecules adsorbed on these structures self-orients along the stripes. Numerical simulations using time-dependent density functional theory allow comparison of computed orbitals of the hexaphenyl molecule with experimental data. Finally, we show that the hexaphenyl molecules can be manipulated along or across the stripes, enabling the molecules to be arranged precisely on the insulating surface.
Bioremediation of Arsenic and Lead by Plants and Microbes from Contaminated Soil

The persistence of heavy metals in the environment may pollute or contaminate soils and aqueous streams as both natural components or as the result of human activity. Bioremediation process in this regards is an option that offers the possibility to destroy or render harmless various contaminants using plants and microbes. Amongst the various bioremediation processes, phytoremediation and bioremediation by microbes are quite effective. Phytoremediation includes the removal of contaminants with the help of green plants, while the microbial bioremediation includes the removal of heavy metals by microorganisms (bacteria, fungi, yeast and algae) as sorbets. Amongst the various heavy metal contaminants arsenic and lead are recognized as the leading toxicants worldwide and having the various toxic effects on human and animal health as well as on the environment. The aim of this article is to give an overview of the arsenic and lead contaminant in soil and also the mechanism of removal of these toxic metals from the contaminated sources by the potent application of plants and microbes.
Changes in immunoglobulin A secretion induced by sympathetic and taste stimulation in the rat submandibular gland

Secretion of saliva is dependent on stimuli from autonomic nerves that are the effector arms of reflexes activated predominantly by taste and chewing. Nerve mediated stimulus evokes saliva secretion of water and proteins by different mechanisms. Secretion of submandibular saliva is controlled by the autonomic nervous system. The parasympathetic nervous system is the main controller of this secretion via impulses in the chorda tympani nerve that innervates it and releases acetylcholine and substance P. Both can evoke copious salivary secretion by activating muscarinic and tachykinin-1 receptors, respectively. In contrast, the sympathetic nervous system also controls salivary secretion by acting on αand βadrenergic receptors. Sympathetic nerve stimulation induced a relatively low flow of saliva that was rich in protein and was accompanied by extensive degranulation from both acinar and granular duct cells. The predominant secretory immunoglobulin on mucosal surfaces is immunoglobulin A (IgA). In the mouth, it is a component of the saliva secreted by the major and minor salivary glands. Secretory immunoglobulin (SIgA) is present in salivary secretions and, along with other glycoproteins such as mucin, lactoferrin and peroxidase, is responsible for helping maintain the integrity of mucosal surfaces against infectious agents. SIgA is the main component of the adaptive immune system. Polymeric, J-chain-conChanges in immunoglobulin A secretion induced by sympathetic and taste stimulation in the rat submandibular gland

The Immediate Safety Profile after Complex Anterior Cervical Reconstruction Surgery

Study design: Retrospective Study. Objective: To identify the spectrum of immediate post-operative complications after complex anterior cervical reconstruction surgery, and the risk factors associated with their occurrence. Summary of background data: Complex anterior cervical reconstruction surgery can be lengthy with more extensive exposure and greater soft tissue disturbance, putting patients at higher risk for immediate complications. Multi-level anterior cervical cases may be associated with a greater number of risks and complications compared to singlelevel anterior cervical discectomy and fusion (ACDF) cases. Methods: A retrospective study of 155 patients between 1996 and 2009 who had undergone complex anterior cervical reconstruction surgery at a single institution by one of three fellowship-trained surgeons. Complex anterior cervical reconstruction surgery cases were defined as: ACDF of 3 or more levels (with or without posterior instrumentation). Hospital charts and operative reports were reviewed for procedurerelated peri-operative complications. Results: Reported complications included dysphagia 41/155 (26.4%), dysphonia 15/155 (9.6%), new nerve palsy 1/155 (0.6%), worsening of preoperative radiculopathy 2/155 (1.3%), post-operative hematoma requiring evacuation 2/155 (1.3%), emergent re-intubation 2/155 (1.3%), and dural tear 1/155 (0.6%). Females (aOR: 2.91, 95% CI: 0.81, 10.49) and fusion of the C3-C4 level (aOR: 3.49, 95% CI: 0.89, 13.29) were found to be predictive characteristics for the onset of dysphagia. Anxiety disorder (aOR: 4.94, 95% CI: 1.06, 22.94) was found to have increased risk of post-operative dysphonia. Increasing Nurick grade, however, was found to have a protective effect on the development of dysphagia (aOR: 0.43, 95% CI: 0.23, 0.80) and dysphonia (aOR: 0.47, 95% CI: 0.26, 0.85). Conclusion: Female gender, fusion of C3-4, and anxiety disorder, were associated with a higher rate of immediate post-operative complications following complex anterior cervical reconstruction surgery. Higher nurick grade was found to have a protective effect on the development of dysphagia and dysphonia.
Interactive comment on “ A dynamic probability density function treatment of cloud mass and number concentrations for low level clouds in GFDL SCM / GCM ” by H

performance of the new scheme, or more precisely, the droplet activation part of the scheme, is demonstrated using three cases with different cloud types and cloud fractions, with an LES model serving as a benchmark. The tests include simulations with two aerosol loadings as well as CLUBB runs at low and high resolutions. While treating subgrid vertical motions is clearly necessary for any realistic SCM simulations of clouds, the goals and benefits of the specific approach needs to be identified more clearly to be useful for the modeling community. The outlined model development seems viable, but a major revision of the manuscript is needed to bring it to the publication level.
Beyond Greedy Ranking: Slate Optimization via List-CVAE

The conventional solution to the recommendation problem greedily ranks individual document candidates by prediction scores. However, this method fails to optimize the slate as a whole, and hence, often struggles to capture biases caused by the page layout and document interdepedencies. The slate recommendation problem aims to directly find the optimally ordered subset of documents (i.e. slates) that best serve users' interests. Solving this problem is hard due to the combinatorial explosion in all combinations of document candidates and their display positions on the page. Therefore we propose a paradigm shift from the traditional viewpoint of solving a ranking problem to a direct slate generation framework. In this paper, we introduce List Conditional Variational Auto-Encoders (List-CVAE), which learns the joint distribution of documents on the slate conditioned on user responses, and directly generates full slates. Experiments on simulated and real-world data show that List-CVAE outperforms popular comparable ranking methods consistently on various scales of documents corpora.
