A novel circular polarized diamond ring-slot antenna design based on SIW structure

A single-layer right-handed circularly polarized (RHCP) substrate integrated waveguide (SIW) diamond ring-slot antenna at X-band is proposed in this paper. With a shorted diamond ring-slot in the top wall of SIW and a shorting via between the top patch and the bottom ground plane, the RHCP wave and wideband impedance bandwidth are obtained at the same time. The measured impedance bandwidth and axial ratio (AR) bandwidth are 14.5% (10.03-11.6GHz) and 3.4% (10.16-10.51GHz), respectively. The antenna has good radiation pattern and high gain than other similar SIW antennas.
Long-term memories and experiences of childbirth in a Nordic context—a secondary analysis

The experience of childbirth is an important life experience for women. However, in-depth knowledge about long-term experiences is limited. The aim of the study was to describe women's experiences two to 20 years after birth. This study is a part of a meta-synthesis project about childbearing in the Nordic countries. Methodologically, the study was a secondary analysis performed on original data from three selected qualitative studies by the authors, in three Nordic countries, Finland, Iceland and Sweden, and in two different forms of care, birth centre care and standard maternity care. There were 29 participants, both primipara and multiparous women. The result from this study shows that women, in a long-term perspective describe childbirth as an encounter with different participants and the most important is with the midwife. The midwife is also important in connection to the atmosphere experienced during birth. The childbirth experience has a potential to strengthen self-confidence and trust in others or, on the contrary, it can mean failure or distrust. Impersonal encounters linger feelings of being abandoned and alone. This dimension is in particular demonstrated in the description of the woman who had given birth at standard maternity care. The conclusion of this study is that childbirth experience has a potential to strengthen self-confidence and trust in others or on the contrary failure or distrust. Maternity care should be organized in a way that emphasis this aspects of care.
The Report of Structural Equation Modeling Analysis Results at Malaysian University Libraries

- The evolutionary of Knowledge Management (KM) has become the key concern for librarians and libraries. This paper reported a SEM through a Confirmatory Factor Analysis (CFA) result that involves 305 lead users at six selected Malaysian university libraries through an online survey. As such, a structural equation modeling (SEM) has been used to generate a versatile statistical modeling tool in the social sciences research. It’s gained popularity across many disciplines, due to its generality and flexibility. This is to elicit opinion of the lead users on the relationship between knowledge processes (i
Evaluation of Two Transgenes for Aluminum Tolerance in Alfalfa

Alfalfa (Medicago sativa L.) production is dra- matically reduced in acidic, Al-rich soil. Trans- genic plants of several species overexpress- ing organic acid synthesis and/or organic acid transporter genes have shown enhanced toler- ance to Al. The objective of this research was to evaluate the effect of the citrate synthase (CS) and the Daucus carota L. plasma membrane H + -transporting adenosine triphosphatase (H + ATPase) (DcPA1) transgenes on Al tolerance in alfalfa. Stem cuttings from a full-sib T 2 popu- lation including four isogenic groups (plants with neither transgene, CS only, DcPA1 only, and both transgenes) together with nontrans- formed check genotypes were evaluated for Al and acid soil tolerance in a greenhouse assay in limed and unlimed soil. Aluminum and acid soil tolerance was assessed by measuring the ratios of root and shoot dry weight in unlimed soil compared to limed soil. The three transgenic populations, CS, DcPA1, and CS plus DcPA1, all showed higher Al and acid soil tolerance and lower levels of Al in shoot tissue than the non- transgenic isogenic population or the nontrans- genic parental genotypes. This suggests that an Al-exclusion mechanism could be driving Al and acid soil tolerance in this study. We observed no advantage of combining both transgenes in the same genetic background. These transgenes offer an efficient method to achieve enhanced Al and acid soil tolerant alfalfa cultivars, but more information is needed on their stability across generations and genetic backgrounds and their performance under field conditions.
An alternative approach to anti‐windup in anticipation of actuator saturation

Traditionally, an anti‐windup compensator is activated when control signal saturation occurs. An alternative approach is to activate the compensator at a level below that of the physical control constraints: the anti‐windup compensator is activated in anticipation of actuator saturation. Recent studies have proposed systematic methods for the construction of such anticipatory anti‐windup compensators, but a pseudo‐LPV representation of the saturated system has been central to these results. This paper approaches the anticipatory anti‐windup problem for open‐loop stable plants using a ‘non‐square’ sector condition, which is associated with a combination of deadzone nonlinearities. The advantage of this approach is that it leads to synthesis routines, which bear a close resemblance to those associated with traditional immediately activated anti‐windup compensators. A by‐product of this approach also appears to be that the arising compensators are better numerically conditioned. Some simulation examples illustrating the effectiveness of anticipatory anti‐windup compensators and some comments on their wider use complete the paper. Copyright © 2016 John Wiley & Sons, Ltd.

Investigation of Random Rough Surface Effects in Interconnect Resistance Extraction Utilizing Effective Conductivity

Due to the decreasing skin depth in high-frequency analog and digital circuits, surface roughness is playing an increasingly important role in interconnect parasitic extraction. However, the inaccessibility of explicit surface expression and the complicated electromagnetic (EM) nature baffle the satisfactory solution to this kind of problems. In this paper, the impact of random surface roughness on the frequency-dependent resistance extraction for interconnects is quantitively evaluated by the concept of effective conductivity. The surface information is given in terms of statistical description instead of explicit functions. We combine the equivalent source method with the Monte Carlo simulation, called generalized equivalent source method (GESM), to analyze the behavior of EM wave on random rough surfaces. These techniques simplify the investigation of rough surface effects in interconnect parasitic extractions and full-wave analyses for signal integrity
Numerical prediction of heat-flux to massive calorimeters engulfed in regulatory fires with the cask analysis fire environment (CAFE) model

Recent observations show that the thermal boundary conditions within large-scale fires are significantly affected by the presence of thermally massive objects. These objects cool the soot and gas near their surfaces, and these effects reduce the incoming radiant heat-flux to values lower than the levels expected from simple {sigma}T{sub fire}{sup 4} models. They also affect the flow and temperature fields in the fire far from their surfaces. The Cask Analysis Fire Environment (CAFE) code has been developed at Sandia National Laboratories to provide an enhanced fire boundary condition for the design of radioactive material packages. CAFE is a set of computer subroutines that use computational fluid mechanics methods to predict convective heat transfer and mixing. It also includes models for fuel and oxygen transport, chemical reaction, and participating-media radiation heat transfer. This code uses two-dimensional computational models so that it has reasonably short turnaround times on standard workstations and is well suited for design and risk studies. In this paper, CAFE is coupled with a commercial finite-element program to model a large cylindrical calorimeter fully engulfed in a pool fire. The time-dependent heat-flux to the calorimeter and the calorimeter surface temperature are determined for several locations around the calorimeter circumference. The variation of heat-flux with location is determined for calorimeters with different diameters and wall thickness, and the observed effects discussed.
THE DYNAMICAL SYSTEMS APPROACH TO DIFFERENTIAL EQUATIONS

This harmony that human intelligence believes it discovers in nature —does it exist apart from that intelligence? No, without doubt, a reality completely independent of the spirit which conceives it, sees it or feels it, is an impossibility. A world so exterior as that, even if it existed, would be forever inaccessible to us. But what we call objective reality is, in the last analysis, that which is common to several thinking beings, and could be common to all; this common part, we will see, can be nothing but the harmony expressed by mathematical laws.
On the development and simulation of a robotic ultrasound guided system for orthopedic surgical procedures

Surgical navigation is a crucial concept in computer assisted surgery. The use of robots in the surgery room largely benefits from this concept recent developments, namely with the use of non-invasive and radiation free imaging systems, like ultrasound (US). This paper presents the algorithms and software tools developed for US based orthopedic surgery navigation. In the second part of the paper are presented the algorithms and software tools developed for controlling a robotic manipulator, that can be used both in simulation and in a real scenario. The paper also presents the developed simulation scenario, for a surgical procedure in Hip Resurfacing, e.g., the first drill of the femur head. For navigation, the system, during surgery, acquires a 3D US bone surface from a sequence of US images. This bone surface will then be registered to the pre-operative bone model, for a precise knowledge of the bone position and orientation. The measured bone movement is used by the simulation tool to control the robot manipulator drilling trajectory.
Multiport antenna systems for MIMO and diversity

Recent trend to minimize the mobile phone antenna size is to use the chassis as the main radiator especially at lower frequencies. Providing multiple antenna support for these small devices is more challenging due to large coupling between the antenna ports. However, with the help of characteristic modes of conducting bodies, it becomes possible to realize up to four port antenna systems that have acceptable return loss over 2.4 GHz ISM band and the cross-talk is less than −20 dB over the band of interest.
Cryogenic scintillators in searches for extremely rare events

Inorganic scintillators are important elements of a new type of cryogenic phonon scintillation detector (CPSD) being developed for single particle detection. These detectors, exhibiting superior energy resolution and the ability to identify the type of interaction in an event, are considered to be the next generation of instrumentation in the search for extremely rare events. This paper presents the latest results of our research on cryogenic scintillators for CPSD applications in the search for dark matter. The paper gives a description of the concept of direct dark matter detection and the operation principles of CPSD, discusses the major material requirements and summarizes the results of investigations over a wide temperature range of the luminescence and scintillation properties of tungstates (CaWO4 and ZnWO4), molybdates (CaMoO4, MgMoO4 and CdMoO4) and Ti-doped Al2O3.
Learning Compact Geometric Features Supplementary Material

Recall that our proposed input parameterization is R = 17 subdivisions in the radial direction, E = 11 in the elevation direction, A = 12 in the azimuth direction, and a search radius of 17% of the diameter of the model. The resultant dimensionality of the input histogram is N = 2,244. In each experiment we select one of these parameters and consider the parameterization resulting from changing this value by ±2.
Addressing data sparsity in DNN acoustic modeling

This paper presents our work on developing acoustic models using deep neural networks (DNN) for low resource languages. This is considered one of the challenging problems in automatic speech recognition (ASR) as DNNs need large amount of data for building efficient models. The techniques explored in this approach use a common idea of transferring knowledge from models of high resource language to a low resource language. These methods include: (i) cross-lingual approach of building a common DNN model with data from a low resource language pooled with a linguistically close high resource language, (ii) transfer learning approach by adapting the top one or more layers of a pooled DNN model with low resource data, (iii) multitask learning approach by treating each language as a separate task for a common model trained over multiple related tasks simultaneously, which alleviates over-fitting problems. The multi-task method was found to be the most effective of all. Experiments were done on Kannada (low resource) and Telugu data and 46% relative improvement is observed in multi-task framework over its mono-lingual DNN.
Screening of Gestational Diabetes Mellitus with 75gm OGTT and its effects on Feto-maternal Outcome

Our study was designed to find out the incidence of Gestational Diabetes Mellitus by using 75 gm oral glucose tolerance test as a single step procedure to both screen and diagnose and to know the effects of gestational diabetes towards maternal and fetal outcome. 500 pregnant women with singleton pregnancy were screened with 75 gm oral glucose tolerance test. Those with 2 hour venous plasma glucose of  140mg/dl were diagnosed as gestational diabetes and were put under medical nutrition therapy or insulin. All the cases were followed up till delivery for fetal and maternal outcome. The overall incidence of gestational diabetes mellitus was 5.2%. It was more common in obese patients, with family history of diabetes and in multigravidas. Maternal complications like vaginal candidiasis, hypertension, polyhydramnios, and preterm labour were more common in diabetic group. Fetal outcomes like macrosomia, shoulder dystocia, still birth, hypoglycemia, congenital anomalies, trauma during delivery were all found to be more in patients with gestational diabetes. The rise in prevalence of Gestational Diabetes in our community and its associated increased risk of pregnancy and delivery complications justifies a need to screen pregnant mothers who attend the antenatal clinic. This single step procedure (75gm OGTT) is a simple economic and feasible method. It serves both for the purpose of screening and diagnosis at the same time.
Syphilis in a Nigerian paramilitary agency: need for treatment policy

Background : Sexually transmitted diseases are widespread in the developing countries and constitute a major public health problem in Sub-Saharan Africa. More recently, there has been a resurgence of syphilis. The aim of this study was to determine the seroprevalence rate of syphilis among newly recruited senior cadres of a Nigerian Security Agency. Method : Eight hundred and fifteen newly recruited men and women sent for serological test for syphilis (STS) in our laboratory were all screened accordingly using Rapid Plasma Reagin (RPR) test. All those that were positive wee confirmed using treponema pallidum haemagglutination (TPHA) test. Results : The seroprevalence rate of treponema pallidum infection was 4.0% (95%CI = 2.8% -5.6%). The rate was significantly higher among women (8.0%) compare to men (3.4%) (X 2 = 5.3 df = 1 P = 0.02). Considered by age, the highest seroprevalence of 6.7% was seen among oldest recruits (30-39) years age group compared to 4.2% among the younger ones. This trend was however, not statistically significant (X 2 trend = 1.6 df =3 P = 0.20). Conclusion : Syphilis seropositivity is highly prevalent among the paramilitary population hence the need for prophylactic treatment with benzathine penicillin to be instituted for seropositive individuals as a matter of policy by the government. This could reduce the incidence of HIV infection among Nigerians. Keywords : syphilis, sexually transmitted diseases, seroprevalence Annals of African Medicine Vol. 4(4) 2005: 177–179

DISCOVERY OF A SUBSTELLAR COMPANION TO THE NEARBY DEBRIS DISK HOST HR 2562

We present the discovery of a brown dwarf companion to the debris disk host star HR 2562. This object, discovered with the Gemini Planet Imager (GPI), has a projected separation of 20.3 ± 0.3 au ( ) from the star. With the high astrometric precision afforded by GPI, we have confirmed, to more than 5σ, the common proper motion of HR 2562B with the star, with only a month-long time baseline between observations. Spectral data in the J-, H-, and K-bands show a morphological similarity to L/T transition objects. We assign a spectral type of L7 ± 3 to HR 2562B and derive a luminosity of log(L / , corresponding to a mass of 30 ± 15 from evolutionary models at an estimated age of the system of 300–900 Myr. Although the uncertainty in the age of the host star is significant, the spectra and photometry exhibit several indications of youth for HR 2562B. The source has a position angle that is consistent with an orbit in the same plane as the debris disk recently resolved with Herschel. Additionally, it appears to be interior to the debris disk. Though the extent of the inner hole is currently too uncertain to place limits on the mass of HR 2562B, future observations of the disk with higher spatial resolution may be able to provide mass constraints. This is the first brown-dwarf-mass object found to reside in the inner hole of a debris disk, offering the opportunity to search for evidence of formation above the deuterium burning limit in a circumstellar disk.
Governing the Compact City: The Challenges of Apartment Living in Sydney, Australia

This paper addresses the challenges facing the strata sector in Sydney in the context of current Australian metropolitan planning strategies promoting increased urban consolidation. It argues that the current focus on higher density development is vulnerable to challenges of regulation, representation and termination in strata developments. Furthermore, the increasing size and complexity of strata schemes as well as the existence of ageing strata stock are placing pressure on the strata title system in NSW and these problems are likely to escalate as an increasing proportion of the population move into strata. Therefore, it is essential to comprehend the issues facing strata developments if they are to be effectively tackled. The concept of ‘governance’ provides one mechanism for improving this understanding.
Identification of Changes in Gene Expression Induced by Toxic Agents: Implications for Therapy and Rapid Diagnosis

Abstract : In our changing world, there has been a significant increase in both the nature and degree of the threat posed by the use of biological agents. Studies for many years have focused on rapid detection of known biological threat agents using structural-based probes designed and directed toward features of the pathogenic agent. However, concerns relating to unidentifiable pathogens, that could result from either deliberate or natural mutation processes have prompted studies to find alternative approaches. Our thesis was that an exposed individual would show gene expression responses unique to the pathogenic agent and prior to onset of the full illness. Therefore this study focused on use of peripheral blood mononuclear cells (PBMC) as a readily accessible reservoir of historical information for development of a library of host gene expression responses to known biological threat agents. The gene responses seen in this accessible tissue would be a compilation of both primary and secondary effects on PBMC and would present a signature pattern of a specific biological threat agent. This study describes our work to establish a library of host responses to pathogenic agents for use to a) predict the course of impending illness especially for unidentifiable pathogens so that appropriate therapeutic intervention can be initiated, b) to characterize the degree of individual exposure in order to assist health personnel to rapidly differentiate those who will become seriously ill from "the worried well" individuals and c) reveal new therapeutic targets that can be initiated even in late- stage illness caused by biological threat agents.
A temperature-compensated current source with high output impedance

In this paper we describe the design and simulations of an accurate low compliance voltage current source with high output impedance in 1.8-V, 0. 18μm CMOS technology, which compensated from temperature variations. Using a second-order temperature compensated current reference caused to obtain approximately temperature-independent current source. Also in this design we achieved high output impedance by using a negative feedback, without increasing Compliance voltage. The simulation results show that compliance voltage is 165-mV at 50μA and its temperature coefficient is 87 ppm/°C in temperature range from 0°C to 120°C. It is important to noted, three main specifications of current sources, temperature independence, high output impedance and low compliance voltage are achieved in proposed circuit. The total consumption power is 206 μW at 1.8 supply voltage.
