Ultra-wide body-bias range LDPC decoder in 28nm UTBB FDSOI technology

This paper presents an IEEE 802.11n Low-Density Parity-Check (LDPC) decoder implemented in 28nm Ultra-Thin Body and BOX Fully Depleted SOI (UTBB FDSOI), and demonstrates the performance gains of this circuit vs. 28nm LP high-κ metal-gate CMOS bulk technology. It also introduces extended body bias (BB) design techniques to take advantage of specific features of the UTBB technology to overcome the +/-300mV BB range limitation of conventional bulk technologies [1].
A Vision-based travelled Distance estimation Algorithm in an indoor Environment using a Mobile robot

Autonomous navigation for a mobile robot still remains as a challenging area to be explored. In an indoor environment, while GPS is unavailable and wheel encoder suffer from error accumulation due to wheel slips, vision-based travelled distance estimation can be considered as an alternative approach for more accurate measurements. This study presents a new algorithm to estimate travelled distance of the mobile robot in an indoor environment. Using a downward looking camera, features points are detected from the floor texture and tracked with the Lucas-Kanade optical flow technique. The measurement accuracy of this algorithm will be put through several experiments on real scenarios which involve comparing the proposed techniques, running the algorithm on different type of indoor surface at different speed and different trajectories.
Head Capsule Width as an Instar Indicator for Larvae of the Cranberry Fruitworm (Lepidoptera: Pyralidae) in Southeastern New Brunswick

Abstract The objective of this study was to determine the number of instars of the cranberry fruitworm Acrobasis vaccinii Riley in southeastern New Brunswick based on the distribution of head capsule widths from field and laboratory observations. In 2000, head capsules from field samples were measured across their widest point, and the results were plotted against observed frequencies. The data from field samples suggested that A. vaccinii exhibited five instars in 2000. In 2001, larvae were reared in the laboratory until the final molt, and head capsules were counted and measured. The results were also plotted against observed frequencies. None of the laboratory specimens exhibited more than five instars, supporting the results of the previous year. Various factors are invoked to explain the difference between these results and those of a previous study conducted 50 yr earlier and 200 km away, in which six instars and larger head capsules were reported.
Ultrasound strain measurements for evaluating local pulmonary ventilation

Local lung function is difficult to evaluate, because most lung function estimates are either global in nature, e.g. pulmonary function tests, or require equipment that cannot be used at a patient's bedside, such as computed tomograms. Yet, local function measurements would be highly desirable for many reasons. In a recent publication [1], we were able to track displacements of the lung surface during breathing. We have now extended these results to measuring lung strains during respiration as a means of assessing local lung ventilation. We studied two normal human volunteers and 12 mice with either normal lung function or experimentally induced pulmonary fibrosis. The difference in strains between the control, normal mice and those with pulmonary fibrosis was significant (p <; 0.02), while the strains measured in the human volunteers closely matched linear strains predicted from the literature. Ultrasonography may be able to assess local lung ventilation.
SCOTCH: Secure Counting Of encrypTed genomiC data using a Hybrid approach

As genomic data are usually at large scale and highly sensitive, it is essential to enable both efficient and secure analysis, by which the data owner can securely delegate both computation and storage on untrusted public cloud. Counting query of genotypes is a basic function for many downstream applications in biomedical research (e.g., computing allele frequency, calculating chi-squared statistics, etc.). Previous solutions show promise on secure counting of outsourced data but the efficiency is still a big limitation for real world applications. In this paper, we propose a novel hybrid solution to combine a rigorous theoretical model (homomorphic encryption) and the latest hardware-based infrastructure (i.e., Software Guard Extensions) to speed up the computation while preserving the privacy of both data owners and data users. Our results demonstrated efficiency by using the real data from the personal genome project.
Comparative study of efficacy and tolerability of Olmesartan with Ramipril in Type II diabetic and hypertensive Patients

Background: Type 2 Diabetes Mellitus is commonly associated with hypertension. The reninangiotensin-aldosterone system (RAAS) plays a pivotal role in the pathogenesis of insulin resistance and cardiovascular disease in diabetes. Interruption of the RAAS with Angiotensin II type 1, (AT) receptor blockers (ARB) has been shown to prevent or reduce cardiovascular and renal disease progression in diabetic patients with hypertension. With this background we tried to evaluate the efficacy and tolerability of Olmesartan and Ramipiril. Methods: Study was conducted on 60 pa ents who were known diabe cs and hypertensive a ending the General Medicine clinic of Prathima Institute of medical Sciences Karimnagar. Results: The mean difference of 16 in SBP and mean difference of 7.69 in DBP in Ramipril group. Similarly mean difference of 19.8 in SBP and mean difference of 10 in DBP in Olmesartan group. The changes in both groups were statistically significant t-test shows the changes in Olmesartan group was found to be significant. There was mean difference of 4.19 in serum urea, mean difference of 0.05 in serum crea nine and mean difference of 8.21 in albuminuria in Ramipril group. Similarly mean difference of 4.44 in serum urea, mean difference of 0.13 in serum crea nine and mean difference of 24.8 in albuminuria in Olmesartan group. The changes in both groups were statistically significant t-test comparison of the changes in Olmesartan group was found to be significant. Conclusions: Olmesartan is a better choice in patients with type 2 Diabetes Mellitus with hypertension in comparison to Ramipril because of Better antihypertensive effect with achievement of target level blood pressure Better glycemic control (both short term and long term). Better improvement of serum creatinine and Urinary Albumin to Creatinine ratio and
Neural Network-Based Identification and Approximate Predictive Control of a Servo-Hydraulic Vehicle Suspension System

This paper presents multi-layer feedforward neural network-based identification and approximate predictive controller (NNAPC) for a two degree-of-freedom (DOF), quarter-car servohydraulic vehicle suspension system. The nonlinear dynamics of the servo-hydraulic actuator is incorporated in the suspension model. A suspension travel controller is developed to improve the ride comfort and handling quality of the system. A SISO neural network (NN) model based on Nonlinear AutoRegressive with eXogenous input (NARX) is developed using input-output data sets obtained from mathematical model simulation. The NN model was trained using Levenberg-Marquardt algorithm. The NNAPC was used to predict the future responses that are optimized by cost minimization. The proposed controller is compared with a constant-gain PID controller (based on Ziegler-Nichols tuning method) during suspension travel setpoint tracking in the presence of deterministic road disturbance. Simulation results demonstrate the superior performance of the NNAPC over the generic PID controller in adapting to the deterministic road disturbance.
Towards Research Performance in the Humanities

This paper describes a general methodology for developing bibliometric performance indicators. Such a description provides a framework or paradigm for application-oriented research in the field of evaluative quantitative science and technology studies, particularly in the humanities and social sciences. It is based on our study of scholarly output in the field of Law at the four major universities in Flanders, the Dutch speaking part of Belgium. The study illustrates that bibliometrics is much more than conducting citation analyses based on the indexes produced by the Institute for Scientific Information (ISI), since citation data do not play a role in the study. Interaction with scholars in the fields under consideration and openness in the presentation of the quantitative outcomes are the basic features of the methodology. Bibliometrics should be used as an instrument to create a mirror. While not a direct reflection, this study provides a thorough analysis of how scholars in the humanities and social sciences structure their activities and their research output. This structure can be examined empirically from the point of view of its consistency and the degree of consensus among scholars. Relevant issues can be raised that are worth considering in more detail in followup studies, and conclusions from our empirical materials may illuminate such issues. We argue that the principal aim of the development and application of bibliometric indicators is to stimulate a debate among scholars in the field under investigation on the nature of scholarly quality, its principal dimensions, and operationalizations. This aim provides a criterion of productivity of the development process. We further contend that librarians are not infrequently requested to provide assistance in collecting data related to research performance assessments, and that the methodology described in the paper aims at offering a general framework for such activities, and can be used by librarians as a line of action whenever they become involved.
Flow dynamics through spinal needles

We examined the flow pattern produced when liquid dye was actively injected into a fluid medium at various flows through five different commonly used spinal needles. At all flows, the Whitacre‐type needles produced a directional stream exiting at an angle from the longitudinal axis. At intermediate rates the stream developed tracks which disappeared at faster rates. The Quincke needle always produced an undeviated stream of dye and did not form tracks at any flow rate. When a perspex plate (representing the spinal cord) was interposed in front of the needle, the dispersion of dye was always unidirectional from the Whitacre needle and bidirectional from the Quincke needle. The dye adhered to the surface of the plate as a concentrated film at slow rates and at faster rates it dispersed turbulently for both types of needle.
A Review: MIML Framework and Image Annotation

— This review paper creates a bridge between MIML classification framework and Image annotation. There are generally four classification frameworks, known as Single Instance Single Label (SISL), Multi-Instance Learning (MIL), Multi-Label Learning (MLL) and Multi-Instance Multi-Label Learning (MIML). This paper introduces various classification frameworks with examples and related algorithms. An annotation is one type of metadata that can be attached to any video, image (2D/3D), text, audio and other data in the form of explanation, comments, navigation or presentational markup. This paper briefly introduces different types of annotation, annotation dataset, techniques and current research challenges in annotations
Supporting Undergraduate Research: Recommending Personalized Research Projects to Undergraduates

Undergraduates’ participation in faculty-mentored research is becoming an important issue in tertiary education in recent years, and it benefits both undergraduates and faculty members. In reality, many faculty members have research projects that need help from undergraduates, but undergraduates can hardly find the information, which creates information asymmetry problem. Besides, undergraduates lack the experience of doing academic research, the research interest information is incomplete, so they have difficulties in choosing suitable research projects. Thus recommender systems are necessary to facilitate undergraduates’ participation in research projects. Traditional recommendation approaches require relative complete information for decision making, and they can hardly meet the requirements as undergraduates’ research information is incomplete. In this study, we propose a two-stage model that integrates content-based method with collaborative method by leveraging research social networks, where undergraduates are encouraged to connect with faculty members and participate in social network activities, through which research information is collected. The proposed two-stage model alleviates the problems of information asymmetry and incomplete information. The recommender system has been developed in ScholarMate (www.scholarmate.com), and it allows undergraduates to choose suggested research projects.
Street Children and Street Life in Urban Tanzania: The Culture of Surviving and its Implications for Children's Health

This paper presents data from an in-depth study conducted among street children in an urban setting in Tanzania. It examines the reasons 'children of the street' leave their homes, how they survive and meet their daily needs, what problems they encounter whilst on the streets and how they surmount them. The paper also examines the implications of street life for children's health. The findings show that general poverty lies at the center of the increasing number of street children in Tanzania. Street life makes the children vulnerable to a variety of problems including ill health. Policies in Tanzania have so far failed to solve this problem, particularly because social policies have been dealing with symptoms rather than essential causes. The paper ends by outlining short- and long-term policy solutions and also suggests directions for future research and early intervention. Copyright Joint Editors and Blackwell Publishers Ltd 1999.
Analysis of Sequence and Structural Features That Identify the B/C Motif of U3 Small Nucleolar RNA as the Recognition Site for the Snu13p-Rrp9p Protein Pair

ABSTRACT The eukaryal Snu13p/15.5K protein binds K-turn motifs in U4 snRNA and snoRNAs. Two Snu13p/15.5K molecules bind the nucleolar U3 snoRNA required for the early steps of preribosomal processing. Binding of one molecule on the C′/D motif allows association of proteins Nop1p, Nop56p, and Nop58p, whereas binding of the second molecule on the B/C motif allows Rrp9p recruitment. To understand how the Snu13p-Rrp9p pair recognizes the B/C motif, we first improved the identification of RNA determinants required for Snu13p binding by experiments using the systematic evolution of ligands by exponential enrichment. This demonstrated the importance of a U·U pair stacked on the sheared pairs and revealed a direct link between Snu13p affinity and the stability of helices I and II. Sequence and structure requirements for efficient association of Rrp9p on the B/C motif were studied in yeast cells by expression of variant U3 snoRNAs and immunoselection assays. A G-C pair in stem II, a G residue at position 1 in the bulge, and a short stem I were found to be required. The data identify the in vivo function of most of the conserved residues of the U3 snoRNA B/C motif. They bring important information to understand how different K-turn motifs can recruit different sets of proteins after Snu13p association.
Acute afferent loop syndrome in the early postoperative period following pancreaticoduodenectomy.

INTRODUCTION Afferent loop syndrome (ALS) is a recognised complication of foregut surgery caused by mechanical obstruction at the gastrojejunostomy anastomosis itself or at a point nearby. Acute ALS has only been reported following pancreaticoduodenectomy (PD) after several years due to recurrence of malignancy at the anastomotic site. We report five cases of acute ALS in the first postoperative week. METHODS The presentation, clinical findings and successful management of the 5 patients with ALS were obtained from a prospectively collected database of 300 PDs. All five patients with early acute ALS presented with signs and symptoms of a bile leak. Since the fifth patient, the surgical technique has been modified with the creation of a larger window in the transverse mesocolon and a Braun enteroenterostomy. RESULTS There have been no further incidents of ALS since the adoption of these modifications to the standard technique of PD and there has also been a reduction in postoperative bile leaks (6.4% vs 3.6%, p=0.416). CONCLUSIONS Acute ALS is a rare but important complication in the immediate postoperative period following PD and causes disruption to adjacent anastomoses, resulting in a bile leak. A prophylactic Braun anastomosis and wide mesocolic window may prevent this complication and subsequent deterioration.
A comparison of radio frequency interference within and outside of allocated passive earth exploration bands at 10.65 GHz and 18.7 GHz using the GPM microwave imager and windsat

Radio Frequency Interference (RFI) continues to be an annoyance to passive microwave remote sensing as spectrum demands escalate. For microwave imagers such as GMI and WindSat, the X-band and Ku allocated passive bands exhibit RFI from terrestrial based sources and from space-based geostationary satellites reflecting from the ocean, lakes, frozen ground, and other reflective surfaces. The GMI bands were designed to maintain the 3-dB bandpasses within the ITU allocated Earth Exploration-Passive bands, while WindSat, due to its sensitivity requirements, has much wider bandpasses. Both sensors have very similar viewing geometries, creating an ideal situation to address the question “Is it worth compromising radiometric sensitivity with lower bandwidths to stay within the allocated bands. ” We find that the only benefit for these sensors of remaining within the allocated band is the elimination of reflected RFI from geosynchronous satellites around Europe at 10 GHz. Other than that, remaining within the protected bands appears to not provide much benefit.
Consequences of inadequate analgesia during painful procedures in children.

OBJECTIVE To explore the effect of inadequate analgesia for painful procedures (bone marrow aspiration, lumbar puncture, or both) on the pain of subsequent procedures. DESIGN A cohort of patients with cancer who had participated in a placebo-controlled, randomized study that documented the efficacy of oral transmucosal fentanyl citrate for painful procedures rated the pain associated with subsequent procedures performed with open-label oral transmucosal fentanyl. PARTICIPANTS Twenty-one children undergoing diagnostic procedures who had been participants in previous study. INTERVENTION All children were given oral transmucosal fentanyl, 15 to 20 microgram/kg, prior to the procedure; at its conclusion they were asked to rate the associated pain. RESULTS In children younger than 8 years (n = 13), mean pain ratings during each subsequent procedure were consistently higher for those who had received placebo (n = 8) in the original study compared with those who had received the active drug (n = 5). A repeated-measures analysis of variance suggests that this difference is statistically significant (P = .04). Older children (n = 8) did not show this pattern. CONCLUSION Inadequate analgesia for initial procedures in young children may diminish the effect of adequate analgesia in subsequent procedures.
Predicting High-order Chromatin Interactions from Human Genomic Sequence using Deep Neural Networks

Background. Understanding and modeling high-order chromatin organization is a fundamental problem in computational genomics. Chromosome fold into complex shapes by itself mostly by following rules written in the genomic sequence. People have been studying the process closely trying to discover the rules from measured interaction frequencies in Hi-C matrix. Following recent success in using deep learning to model point interactions such as enhancer-promoter interactions directly from genomic sequence, there seems to be similar pathway from genomic sequence to general Hi-C interactions, which leads to modeling general rules behind high-order chromatin interactions.
Potential of a Cetuximab‐based radioimmunotherapy combined with external irradiation manifests in a 3‐D cell assay

Targeting epidermal growth factor receptor (EGFR)‐overexpressing tumors with radiolabeled anti‐EGFR antibodies is a promising strategy for combination with external radiotherapy. In this study, we evaluated the potential of external plus internal irradiation by [90Y]Y‐CHX‐A″‐DTPA‐C225 (Y‐90‐C225) in a 3‐D environment using FaDu and SAS head and neck squamous cell carcinoma (HNSCC) spheroid models and clinically relevant endpoints such as spheroid control probability (SCP) and spheroid control dose 50% (SCD50, external irradiation dose inducing 50% loss of spheroid regrowth). Spheroids were cultured using a standardized platform. Therapy response after treatment with C225, CHX‐A″‐DTPA‐C225 (DTPA‐C225), [90Y]Y‐CHX‐A″‐DTPA (Y‐90‐DTPA) and Y‐90‐C225 alone or in combination with X‐ray was evaluated by long‐term monitoring (60 days) of spheroid integrity and volume growth. Penetration kinetics into spheroids and EGFR binding capacities on spheroid cells were identical for unconjugated C225 and Y‐90‐C225. Spheroid‐associated radioactivity upon exposure to the antibody‐free control conjugate Y‐90‐DTPA was negligible. Determination of the SCD50 demonstrated higher intrinsic radiosensitivity of FaDu as compared with SAS spheroids. Treatment with unconjugated C225 alone did not affect spheroid growth and cell viability. Also, C225 treatment after external irradiation showed no additive effect. However, the combination of external irradiation with Y‐90‐C225 (1 µg/ml, 24 hr) resulted in a considerable benefit as reflected by a pronounced reduction of the SCD50 from 16 Gy to 9 Gy for SAS spheroids and a complete loss of regrowth for FaDu spheroids due to the pronounced accumulation of internal dose caused by the continuous exposure to cell‐bound radionuclide upon Y‐90‐C225‐EGFR interaction.
Iron Requirements in Infancy and Childhood

A critical characteristic of iron nutrition in infancy, as compared to adults, is the greater dependency of the infant on external sources of iron for daily red cell production. Dallman et al. (1) have calculated that in a 1-year-old, 10-kg infant, dietary iron must provide 30% of the needs for hemoglobin iron turnover as compared to only 5% in the adult male (Table 1). This imposes disproportionate requirements of iron to the infant. In addition, infants may (a) consume diets with a low iron content or poor iron availability; (b) be born with decreased iron reserves, as is the case with premature infants; (c) grow too rapidly and have excessive demands; or (d) have increased iron losses. The sum of these factors explains the high occurrence of iron deficiency observed at this age. The main factors determining iron requirements in infants and children are the iron endowment at birth, the requirements for growth, and the need to replace losses.
Compact quasi-elliptic combline filter in single-layered SIW technology with two tunable transmission zeros

In this letter, a novel 3-order combine filter, based on substrate integrated waveguide (SIW) technology, is proposed. Two mixed electric-magnetic(EM) couplings between three resonators introduce two independently controllable transmission zeros(TZs) located at both sides of the passband resulting in a flexible quasi-elliptic response. To demonstrate the proposed filter, an example with 8% FBW is designed and measured. The good agreement between simulation and measurement shows the filter with advantages of low loss and high rejection. Besides, it also exhibits other merits such as size reduction from conventional SIW, single-layer and low-cost.
