NOVEL ULTRA-WIDEBAND DISCONE ANTENNA

A double-discone antenna for an ultra-wideband frequency scan is presented. An exquisite assembly of two inverse-feeding discone antennas shows a 30:1 broad bandwidth with VSWR below 2.5 and an omnidirectional radiation pattern. These features make the proposed antenna very suitable for both the UWB system antenna and the wideband scan antenna. © 2004 Wiley Periodicals, Inc.

The two faces of Narcissus ? An empirical comparison of the Narcissistic Personality Inventory and the Pathological Narcissism Inventory

Areas of convergence and divergence between the Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988) and the Pathological Narcissism Inventory (PNI; Pincus et al., 2009) were evaluated in a sample of 586 college students. Summary scores for the NPI and PNI were not strongly correlated (r = .22) but correlations between certain subscales of these two inventories were larger (e.g., r = .71 for scales measuring Exploitativeness). Both measures had a similar level of correlation with the Narcissistic Personality Disorder scale from the Personality Diagnostic Questionnaire-4 (Hyler, 1994) (r = .40 and .35, respectively). The NPI and PNI diverged, however, with respect to their associations with Explicit Self-Esteem. Selfesteem was negatively associated with the PNI but positively associated with the NPI (r = .34 versus r = .26). Collectively, the results highlight the need for precision when discussing the personality characteristics associated with narcissism. 2010 Elsevier Ltd. All rights reserved.
Esophagitis dissecans associated with eosinophilic esophagitis in an adolescent

Esophagitis dissecans superficialis and eosinophilic esophagitis are distinct esophageal pathologies with characteristic clinical and histologic findings. Esophagitis dissecans superficialis is a rare finding on endoscopy consisting of the peeling of large fragments of esophageal mucosa. Histology shows sloughing of the epithelium and parakeratosis. Eosinophilic esophagitis is an allergic disease of the esophagus characterized by eosinophilic inflammation of the epithelium and symptoms of esophageal dysfunction. Both of these esophageal processes have been associated with other diseases, but there is no known association between them. We describe a case of esophagitis dissecans superficialis and eosinophilic esophagitis in an adolescent patient. To our knowledge, this is the first case describing an association between esophageal dissecans superficialis and eosinophilic esophagitis.

Rare origin of the inferior epigastric artery from an anomalous medial circumflex femoral artery.

Correspondence Rare origin of the inferior epigastric artery from an anomalous medial circumflex femoral artery Mathes & Bostwick (1977) surgically manipulated the rectus abdominis myocutaneous flap to repair defects in the anterior abdominal wall. Subsequently this flap was used in breast reconstruction (Robbins, 1981 ; Hartrampf et al. 1982) as a donor for free-tissue transfer (Bunkis et al. 1983) and to repair defects in the groin (Logan & Mathes, 1984 ; Ramasastry et al. 1989). Disadvantages of this flap are that it can be too thick to use effectively and a direct abdominal hernia may occur through the inguinal triangle To overcome these disadvantages the rectus abdominis and the fascia covering the inguinal triangle must be intact. Surgeons therefore harvested the inferior epigastric skin flap for free-tissue skin transfer ; this flap contained little or no rectus abdominis muscle or transversalis fascia (Koshima & Soeda, 1989). Previous investigators determined the anatomical basis for the use of this skin flap and used it to repair defects following resection of ulcers and scar tissue on the head, neck and extremities (Itoh & Arai, 1993). Viability of these flaps is dependent on the integrity of their blood supply following transposition or transplan-tation. Due to its surgical relevance the origin, course, distribution and anomalies of the inferior epigastric artery (IEA) have been studied (Bergman et al. 1984 ; Taylor et al. 1984 ; San4 udo et al. 1993). Previous researchers have shown that, within the greater pelvis, the IEA may arise from a common trunk with the obturator and medial circumflex femoral arteries (San4 udo et al. 1993) or as a common trunk with the deep circumflex femoral artery (Bergman et al. 1984). However, in this male specimen the IEA was a recurrent branch of an anomalous medial circumflex femoral artery (AMC) arising from the external iliac artery (Fig.). As far as the authors are aware this anomaly has not been described. The medial circumflex femoral artery (MCFA) may spring from the profunda femoris or femoral arteries or one of the branches of the external iliac artery (Bergman et al. 1984). This anomalous IEA arose within the femoral triangle and ran superiorly, passing deep to the inguinal ligament, medial to the deep inguinal ring and entered the rectus sheath anterior to the arcuate line (Fig.). Dissection of the right thigh and right side of the anterior abdominal wall of this cadaver revealed that this …
Emerging and re-emerging rickettsioses: endothelial cell infection and early disease events

Rickettsiae cause some of the most severe human infections, including epidemic typhus and Rocky Mountain spotted fever. Substantial progress has been made in research into the genomics, vector relationships, pathogenesis and immunity of these obligate, intracellular, arthropod-transmitted bacteria. This Review summarizes our understanding of the early and late events in pathogenesis and immunity, modulation of the host response to rickettsial infection by the vector, host defence, virulence mechanisms and rickettsial manipulation of host cells.
Efficient FPGA Implementations of High-Dimensional Cube Testers on the Stream Cipher Grain-128

Cube testers are a generic class of methods for building distinguishers, based on cube attacks and on algebraic property-testers. In this paper, we report on an efficient FPGA implementation of cube testers on the stream cipher Grain-128. Our best result (a distinguisher on Grain-128 reduced to 237 rounds, out of 256) was achieved after a computation involving 2 clockings of Grain-128, with a 256×32 parallelization. An extrapolation of our results with standard methods suggests the possibility of a distinguishing attack on the full Grain-128 in time 2, which is well below the 2 complexity of exhaustive search. We also describe the method used for finding good cubes (a simple evolutionary algorithm), and report preliminary results on Grain-v1 obtained with a bitsliced C implementation.
Short- and long-term efficacy of a community-based COPD management programme in less advanced COPD: a randomised controlled trial.

BACKGROUND
The effectiveness of pulmonary rehabilitation in advanced COPD is well established, but few data are available in less advanced disease.


METHODS
In a 2 year randomised controlled trial, 199 patients with an average moderate airflow obstruction but impaired exercise capacity (mean (SD) forced expiratory volume in 1 s (FEV(1)) 60 (16)%, peak work load (Wmax) <70%) were randomised to the INTERdisciplinary COMmunity-based COPD management programme (INTERCOM) or usual care. Intervention consisted of 4 months multidisciplinary rehabilitation followed by a 20-month maintenance phase. Outcomes (4, 12, 24 months): health-related quality of life (St George's Respiratory Questionnaire (SGRQ)), exacerbation frequency, MRC dyspnoea score, cycle endurance time (CET), 6-minute walking distance (6MWD), skeletal muscle strength and patients' and caregivers' perceived effectiveness.


RESULTS
Between-group comparison after 4 months revealed the following mean (SE) significant differences in favour of INTERCOM: SGRQ total score 4.06 (1.39), p = 0.004; activity and impact subscores, p<0.01; MRC score 0.33 (0.13), p = 0.01; Wmax 6.0 (2.3) Watt, p = 0.02; CET 221 (104) s, p = 0.04; 6MWD 13 (6) m, p = 0.02; hand grip force 4.3 (1.5) lb, p<0.01; and fat-free mass index 0.34 (0.13) kg/m(2), p = 0.01. Between-group differences over 2 years were as follows: SGRQ 2.60 (1.3), p = 0.04; MRC score 0.21 (0.10), p = 0.048; CET 253 (104) s, p = 0.0156; 6MWD 18 (8) m, p = 0.0155. Exacerbation frequency was not different (RR 1.29 (95% CI 0.89 to 1.87)). Patients' and caregivers' perceived effectiveness significantly favoured the INTERCOM programme (p<0.01).


CONCLUSIONS
This study shows that a multidisciplinary community-based disease management programme is also effective in patients with COPD with exercise impairment but less advanced airflow obstruction.

Poor self-rated health did not increase risk of permanent nursing placement or mortality in people with mild Alzheimer’s disease

BACKGROUND
Self-rated health (SRH) has in many population-based studies predicted adverse health outcomes, e.g. morbidity, permanent nursing home (NH) placement, and mortality. However, the predictive value of SRH to NH placement and mortality among elderly people is not consistent. This may be due to cognitive impairment. Since the SRH item is widely used, it is important to know whether SRH has different predictive value among people with cognitive impairments. We aimed to examine SRH and the risk of permanent NH placement and mortality among people with mild Alzheimer's disease (AD).


METHODS
Data are from The Danish Alzheimer Intervention StudY (DAISY), a large randomized controlled trial of psychosocial intervention for patients with mild dementia and their caregivers with 3-years' follow-up. Five out of 14 Danish counties participated and 321 home-living elderly (mean age: 76.2 years) with mild AD (46.4 % male) were included during 2004 and 2005. Self-rated SRH, cognitive function (MMSE), quality of life (proxy-rated QOL-AD), activities of daily living (ADCS-ADL), insight, and socio-demographics were assessed at baseline. Comorbidities and information about NH placement and mortality was obtained over 3-years' follow-up from registries. With Cox proportional hazard regression we analysed the association between SRH (dichotomised into good vs. poor) and NH placement and mortality adjusted for potential confounders.


RESULTS
At baseline 66 % reported excellent or good, and 34 % fair, poor or very poor SRH. Mean MMSE was 24.0 (range: 20-30). NH placement and mortality totalled 28.1 % and 16.5 % at 3-years' follow-up, respectively. Poor SRH at baseline was not related to increased risk of NH placement or to increased mortality neither in the univariable nor in multivariable analysis: In the fully adjusted models HR was 0.63 (95 % CI 0.38-1.05) and 1.28 (95 % CI 0.67-2.45), respectively.


CONCLUSIONS
When poor SRH was present we found no increased risk for NH placement or death among elderly people with mild AD. SRH is a widely used parameter in clinical and epidemiological research but may not be a valid indicator of health in patients with AD due to loss of insight.
Diabetes mortality in Panama and related biological and socioeconomic risk factors.

OBJECTIVE
To estimate mortality from diabetes mellitus (DM) for the period 2001-2011 in the Republic of Panama, by province/indigenous territory, and determine its relationship with biological and socioeconomic risk factors.


METHODS
Cases for the years 2001-2011 with DM listed as the principal cause of death were selected from Panama's National Mortality Registry. Crude and adjusted mortality rates were generated by sex, age, and geographic area. Linear regression analyses were performed to determine the relationship between DM mortality and biological and socioeconomic risk factors. A composite health index (CHI) calculated from biological and socioeconomic risk factors was estimated for each province/indigenous territory in Panama.


RESULTS
DM mortality rates did not increase for men or women during 2001-2011. Of the biological risk factors, being overweight had the strongest association with DM mortality. Of the socioeconomic risk factors, earning less than US$ 100 per month had the strongest association with DM mortality. The highest socioeconomic CHI scores were found in a province that is predominantly rural and in areas with indigenous populations. The highest biological CHI scores were found in urban-rural provinces and those with the highest percentage of elderly people.


CONCLUSIONS
Regional disparities in the association between DM mortality and DM risk factors reaffirm the heterogeneous composition of the Panamanian population and the uneven distribution of biological and social determinant risk factors in the country and point to the need to vary management strategies by geographic area for this important cause of disability and death in Panama.

Impact of temperature on surface charges accumulation on insulators in SF6-filled DC-GIL

With this expected future advance of HVDC, the use of gas insulated transmission lines (GIL) for dc application are getting increasingly interesting. For now, the problem of surface charge accumulation on gas-insulator interface is one of the critical factors for the development of DC-GIL. In many previous works, the model of surface charge accumulation on insulator was investigated. However, the quantitative relationship between temperature and surface charge accumulation on insulator was not exactly obtained since the lack of complicated heat transfer progress in the model. In this paper, the heat transfer surface charge accumulation model of operating DC-GIL was developed, including the nonlinear relationship between volume current in gas and electric field. Moreover, the space charge was also considered in the model. Based on the developed model, temperature distributions in DC-GIL insulator under different current are obtained. Afterwards, the temperature impact on space charge density in the insulator, the saturation time of surface charge accumulation, the surface charge on the insulator surface, and the electric field distribution on the insulator were investigated. It was proven that the tangential component of the electric field reaches to 5.3 kV/mm on lower interface and 5.0 kV/mm on upper interface for Ti=378 K. This value increase 17.8% on lower interface and 17.6% on upper interface along with the conductor temperature from 298 K to 378 K. The data can be referred in the insulation design of DC-GIL.
Treatment of postnasal drip with proton pump inhibitors: a prospective, randomized, placebo-controlled study.

BACKGROUND
Patients commonly present with complaints of postnasal drainage (PND) without objective evidence to support a sinonasal or infectious etiology. PND has been attributed to extra-esophageal reflux (EER), and an empiric trial of antireflux medication often is used to treat PND and associated symptoms. This study was performed to (1) evaluate the relationship between symptoms of EER and PND and (2) assess the efficacy of proton pump inhibitors (PPIs) in the management of PND.


METHODS
Patients with a chief complaint of PND without objective evidence of sinonasal inflammatory disease were enrolled in a prospective, double-blinded, randomized placebo-controlled trial using rabeprazole, 20 mg, orally twice daily or placebo for 90 days. Subjects completed two-site 24-hour pharyngeal pH probe monitoring before treatment. Outcome measures included pre- and posttreatment visual analog scales for PND symptoms, reflux symptom index, and reflux finding score (RFS).


RESULTS
Forty-seven patients were enrolled (mean age, 55 years)-21 patients in the PPI group and 26 in the placebo group. Fifty-six percent of subjects had pH probe confirmed EER using a cutoff of pH < 5.0. Baseline symptom measures between subjects with and without EER were not different. Compared with placebo, subjects receiving rabeprazole reported significant reduction in PND frequency (p = 0.0180), hoarseness (p = 0.0164), and chronic cough (p = 0.0204). The RFS decreased slightly in the placebo group (p = 0.1490) whereas it increased slightly in the PPI group (p = 0.5235). This difference between groups was significant (p = 0.0272).


CONCLUSION
Although 50% of subjects had evidence of EER, there was no difference in baseline symptoms between subjects with and without. Our findings support the potential benefit of PPI therapy for reducing PND frequency, hoarseness, and chronic cough, and confirm a placebo effect for other laryngopharyngeal reflux symptoms. The effect on laryngeal findings is mixed and patients may experience symptomatic improvement before changes in laryngoscopic appearance.
‘Third wave’ cognitive therapy versus mentalization-based therapy for major depressive disorder. A protocol for a randomised clinical trial

BACKGROUND
Most interventions for depression have shown small or no effects. 'Third wave' cognitive therapy and mentalization-based therapy have both gained some ground as treatments of psychological problems. No randomised trial has compared the effects of these two interventions for patients with major depression.


METHODS/DESIGN
We plan a randomised, parallel group, assessor-blinded superiority clinical trial. During two years we will include 84 consecutive adult participants diagnosed with major depressive disorder. The participants will be randomised to either 'third wave' cognitive therapy versus mentalization-based therapy. The primary outcome will be the Hamilton Rating Scale for Depression at cessation of treatment at 18 weeks. Secondary outcomes will be the proportion of patients with remission, Symptom Checklist 90 Revised, Beck's Depression Inventory, and The World Health Organisation-Five Well-being Index 1999.


DISCUSSION
Interventions for depression have until now shown relatively small effects. Our trial results will provide knowledge about the effects of two modern psychotherapeutic interventions.

Intrusion Detection using Artificial Neural Network

Intrusion Detection is the task of detecting, preventing and possibly reacting to the attack and intrusions in a network based computer systems. In the literature several machine-learning paradigms have been proposed for developing an Intrusion Detection System. This paper proposes an Artificial Neural Network approach for Intrusion Detection. A Feed Forward Neural Network trained by Back Propagation algorithm is developed to classify the intrusions using a profile data set (ten percent of the KDD Cup 99 Data) with the information related to the computer network during Normal behavior and during Intrusive (Abnormal) behavior. Test result shows that the proposed approach works well in detecting different attacks accurately with less false positive and negative rate and it is comparable to those reported in the literature.
Effect of the inhibition of CYP3A4 or CYP2D6 on the pharmacokinetics and pharmacodynamics of oxycodone

The main metabolic pathways of oxycodone, a potent opioid analgetic, are N-demethylation (CYP3A4) to inactive noroxycodone and O-demethylation (CYP2D6) to active oxymorphone. We performed a three-way, placebo-controlled, double-blind cross-over study to assess the pharmacokinetic and pharmacodynamic consequences of drug interactions with oxycodone. The 12 participants (CYP2D6 extensive metabolizers) were pre-treated with placebo, ketoconazole or paroxetine before oral oxycodone ingestion (0.2 mg/kg). Pre-treatment with ketoconazole increased the AUC for oxycodone 2- to 3-fold compared with placebo or paroxetine. In combination with placebo, oxycodone induced the expected decrease in pupil diameter. This decrease was accentuated in the presence of ketoconazole, but blunted by paroxetine. In comparison to pre-treatment with placebo, ketoconazole increased nausea, drowsiness, and pruritus associated with oxycodone. In contrast, the effect of pre-treatment with paroxetine on the above-mentioned adverse events was not different from that of placebo. Ketoconazole increased the analgetic effect of oxycodone, whereas paroxetine was not different from placebo. Inhibition of CYP3A4 by ketoconazole increases the exposure and some pharmacodynamic effects of oxycodone. Paroxetine pretreatment inhibits CYP2D6 without inducing relevant changes in oxycodone exposure, and partially blunts the pharmacodynamic effects of oxycodone due to intrinsic pharmacological activities. Pharmacodynamic changes associated with CYP3A4 inhibition may be clinically important in patients treated with oxycodone.
