Metamaterials in the far infrared: ideas for left-handed metamaterials and micro- and nanocircuit elements in the terahertz regime

In the present work, the possibility of translating down the concepts of metamaterials into the far-infrared and terahertz regimes, in order to propose ideas for realization of left-handed metamaterials and nano- and micro-circuit elements at few terahertzes are investigated. The terahertz regime, indeed, is a transition region of spectrum between the microwave and the infrared-optical frequencies, where such applications have not been studied in details. The technological interest in scaling up the classic communications and circuit concepts from the radio frequencies (RF) microwaves to higher frequencies is bringing much interest in this regime of frequency
Small-size LTE700/2300/2500 antenna and high-isolation antenna array using the same for the laptop computer

Small-size LTE700/2300/2500 antenna (9 × 45 mm2) and high-isolation antenna array using the same for the laptop computer are presented. The two antennas are mounted along the top edge of the supporting metal plate to be disposed on the inner surface of the upper cover of the laptop computer. Improved isolation (measured S21 better than -30 dB in the LTE700 band and -26 dB in the LTE2300/2500 bands) between the two antennas is easily achieved by adjusting the supporting metal plate to have a length of about 110 mm in the longitudinal direction to the antenna array. The high isolation is obtained because the length is close to a quarter-wavelength of a frequency in the LTE700 band, which makes the excited surface currents in the supporting metal plate stronger in the longitudinal direction and hence causes weaker surface currents flowing along the top edge of the supporting metal plate. This behavior leads to high isolation of the LTE antenna array in this study.

The inner segment/outer segment junction: what have we learnt so far?

Purpose of review The advancement of optical coherence tomography has improved the resolution of in-vivo images of the retina. This has led to a wealth of novel knowledge regarding the microstructures of the photoreceptor layer and its relationship with visual functions under different pathological diseases. Recent findings Identification of the hyperreflective lines in the photoreceptor layer has been made possible by spectral domain optical coherence tomography. The inner segment/outer segment junction, external limiting membrane, cone outer segment tips, and the retinal pigment epithelium were thought to be the origins of the four hyperreflective lines seen in the photoreceptor layer. Integrity of these lines has been linked with visual functions in various retinopathies, and has been suggested to carry prognostic implications. Recovery of initially interrupted lines has been documented following successful treatment. Summary Identification of these hyperreflective lines may have clinical implications as visual function was found to correlate closely with their integrity. Restoration of these lines may indicate treatment response and potential visual recovery.
Successful treatment of Staphylococcus epidermidis prosthetic valve endocarditis with linezolid after failure of treatment with oxacillin, gentamicin, rifampicin, vancomycin, and fusidic acid regimens

We present a 49-y-old male, with a history of Marfan's disease and aortic and mitral valve replacement surgery, who was operated for a type III thoracoabdominal aneurysm. The postoperative course was compromized by a Staphylococcus epidermidis mitral valve endocarditis, which was successfully treated only after intravenous linezolid was included in the therapy.
The utility of a psychological intervention for coping with spontaneous abortion

Background: The object of this study is to implement and to examine the effectiveness a psychological support intervention drawing from three clinical techniques (support, psychoeducation, Cognitive‐Behavioural Therapy) for women who have suffered a spontaneous abortion. Method: 134 women participated in the study: 66 composed the Immediate Intervention group (II) and 68 the Deferred Intervention (DI) group. All participants completed the Hospital Anxiety and Depression Scale (HADS) and the Impact of Events Scale – Revised (IES‐R) at 3 and 10 weeks as well as 6 months following study enrollment. Results: Results at three weeks show significant differences between the groups for anxiety, depression and event impact. Multiple regression analyses showed that intervention group and depression antecedents were significant predictors of overall adaptation after a miscarriage. Conclusions: In terms of prevention, a brief early single‐session psychological intervention appears to be a particularly pertinent, efficacious and cost‐effective method for addressing psychological distress following miscarriage.
Gepirone extended-release: new evidence for efficacy in the treatment of major depressive disorder.

OBJECTIVE To assess the efficacy and tolerability of the 5-HT(1A) agonist gepirone in extended-release formulation (gepirone-ER) versus placebo in patients with major depressive disorder. METHOD Patients aged 18 to 70 years were eligible if they satisfied DSM-IV criteria for moderate-to-severe major depressive disorder and had a baseline 17-item Hamilton Rating Scale for Depression (HAM-D-17) score > or = 20. After a 4- to 7-day placebo washout period, patients were randomly assigned to receive either placebo (N = 106) or gepirone-ER (20-80 mg/day) (N = 103) for 56 days. Assessments were done at weeks 1-4, 6, and 8. RESULTS Mean change from baseline in HAM-D-17 score within the intent-to-treat group (gepirone, N = 101; placebo, N = 103) was significantly greater with gepirone-ER than placebo at weeks 3 (p =.013) and 8 (p =.018). Significantly (p <.05) more patients receiving gepirone-ER than placebo were HAM-D-17 responders at weeks 3 (33.7% vs. 18.8%, respectively) and 4 (38.6% vs. 24.8%, respectively) and HAM-D-17 remitters at weeks 6 (24.8% vs. 13.9%, respectively) and 8 (28.7% vs. 14.9%, respectively). Mean change from baseline for HAM-D-25 total score was significantly (p < pr =.05) greater with gepirone-ER at all assessments except week 6. The proportion of HAM-D-25 responders was significantly greater (p < or =.05) with gepirone-ER at weeks 3 and 8. Gepirone-ER was well tolerated: 9.8% of the gepirone-ER group and 2.8% of the placebo group discontinued due to adverse events. Common adverse events were considered mild and included dizziness, nausea, and insomnia. Gepirone-ER did not differ statistically compared with placebo in weight gain or sedation. Furthermore, preliminary evidence suggested that gepirone-ER may not be associated with sexual dysfunction. No serious adverse events occurred in gepirone-treated patients. CONCLUSION Gepirone-ER is effective for the short-term treatment of major depressive disorder and is well tolerated.
A trial of testosterone therapy for HIV‐associated weight loss

Objective:Weight loss in HIV-infected patients is extremely common and is associated with increased morbidity and mortality. Decreased testosterone concentrations occur commonly in patients with HIV disease and are associated with weight loss. This study assessed the effect of testosterone therapy on HIV associated weight loss in patients with AIDS. Methods:Forty HIV-seropositive patients with CD4+ counts of < 2 × 105/l and weight loss greater than 5% of usual body weight were randomized in a double-blind manner to receive 200 mg of testosterone cypionate or placebo intramuscularly every 2 weeks for 3 months. Patients were then crossed to receive the alternate treatment for the next 3 months. Outcome variables included weight, skin fold measurement, a quality-of-life questionnaire, Karnofsky score, T-cell subset analysis, complete blood count, routine blood chemistry measurements and free testosterone concentration. Results:Thirty-nine patients entered the study. Of these, 35 completed the first 3-month period (18 on placebo, 17 on testosterone) and 23 completed the whole 6 month trial. Analysis of these 23 patients did not show any significant differences between testosterone and placebo treatment. Analysis of the first 3 months only for the 35 patients who completed it did not show any significant difference between the effects of testosterone and placebo treatment on weight gain. Patients treated with testosterone reported improved overall well-being (P = 0.03) and a trend towards increased muscle strength (P = 0.08). There was no difference between the two groups in terms of side-effects or other effects on hematopoetic, liver, renal or immune function. Conclusions:Treatment with testosterone cypionate compared with placebo did not result in significant weight gain. Testosterone supplementation did appear to produce an improved overall sense of well-being and possibly some increase in muscle strength. This randomized, double-blinded study does not confirm the results of other recent studies which show potential benefits of testosterone and its analogs when used as a treatment for weight loss in HIV-positive patients.
Control of haptic interaction : an energy-based approach

Haptic feedback systems are systems that exert a desired force, to be experienced by the user, to recreate a physical interaction. This type of systems can increase the realism of the interaction with objects that are not in the direct area of influence of the user. The same applies to the interaction with virtual objects. The fundamental problem in the control of these systems is how to maximize the transparency of the system, and related to that the realism of the interaction as perceived by the user, while guaranteeing stability of the interaction under all possible operating conditions. The stability analysis is complicated due to the presence of a closed loop, which can contain multiple unknown, non-linear, and time-varying elements, e.g. the user, a physical environment, and time delays in a possible communication channel. Furthermore, the control algorithm is executed on a discrete medium which, depending on the algorithm, parameter settings, and remaining elements, can have a significant influence on the stability of the interaction. In this thesis a solution is sought to all these factors by means of energy- and portbased reasoning. For both applications an algorithm is derived that is based on the energy exchange between the physical world and the system. By enforcing energy neutrality, in other words passivity, of this exchange a stable interaction is guaranteed. The algorithm for the interaction with virtual environments provides a passive coupling between the physical system and the discrete system. The dynamic behavior of the virtual object is computed with an energy-based integration method. Each iteration the algorithm evaluates the energy that is present in the system. A redistribution of that energy over the energy storing elements is computed based on the model that describes the dynamic behavior of the physical object. This algorithm ensures stability independent of the sample frequency of the algorithm, but adapts the realism of the interaction in such a way that passivity is maintained. The second algorithm divides the control objectives for the passive interaction with physical objects in remote environments by means of a telemanipulation system into two layers that are placed in a hierarchical order. The top layer, the Transparency-layer, contains an arbitrary control algorithm that provides the desired measure of transparency. The Passivity-layer contains an algorithm that guarantees passivity of the interaction and when necessary adapts the desired forces computed by the Transparency-layer to maintain passivity. The implementation of this algorithm also works in the presence of communication delays, by e.g. physical distance, between both locations that are connected by the system, the user and remote environment, respectively.
Economic appraisal of maintenance parenteral iron administration in treatment of anaemia in chronic haemodialysis patients.

BACKGROUND Iron deficiency is common in haemodialysis patients and adequate supplementation by the oral or parenteral route has been limited by drug side-effects, absorption, and cost. Intermittent doses of intravenous iron dextran complex are recommended in patients with inadequate iron stores despite maximal tolerated oral dose. We conducted a prospective study with economic analysis of a regular maintenance intravenous iron regimen in this group of patients. METHODS Fifty patients comprising one-half of our haemodialysis population required intravenous iron treatment, i.e. they failed to achieve an arbitrary goal serum ferritin 100 microg/l despite maximal tolerated oral iron dose. After a loading dose of intravenous iron dextran complex (IV-FeD) based on Van Wyck's nomogram (400+/-300 mg) they received a maintenance dose of 100mg IV-FeD once every 2 weeks. Initial goal serum ferritin was set at 100-200 microg/l. If no increase in haemoglobin was achieved at this level, transferrin saturation was measured to assess bioavailable iron, and when less than 20%, goal serum ferritin was increased to 200-300 microg/l. Recombinant human erythropoietin (rHuEpo) was used where needed to maintain haemoglobin in the 9.5-10.5 g/l range only if ferritin requirements were met. Results. Mean haemoglobin rose from 87.7+/-12.1 to 100.3+/-13.1 g/l (P<0.001, Cl 7.7-17.9) at mean follow-up of 6 months (range 3-15 months). In patients on rHuEpo, dose per patient was reduced from 96+/-59 u/kg per week to 63+/-41 u/kg per week, representing a 35% dose reduction (P<0.05, Cl 1-65). An annual cost reduction of $3166 CDN was projected; however, in the first year this is offset by the cost of the loading dose of IV-FeD required at the beginning of treatment. No adverse reactions were encountered. CONCLUSION Iron deficiency is very common in our haemodialysis population, especially in those patients receiving rHuEpo. A carefully monitored regimen of maintenance parenteral iron is a safe, effective, and economically favourable means of iron supplementation in patients with insufficient iron stores on maximum tolerated oral supplements.
A variational level set segmentation formulation based on signal model for images in the presence of intensity inhomogeneity

Biological images with significant intensity inhomogeneity are considerably difficult for the tissue segmentation. To overcome the difficulties caused by the intensity inhomogeneity, this study presents a variational level set method to simultaneous bias field estimation and tissue segmentation for images in the presence of intensity inhomogeneity. An energy function is defined in terms of two data fitting terms which incorporate the local clustering properties into the global region information. First, depended on the observed image mode, the local cluster property based on the observed signal is simplified to a criterion function which is similar to the Mumford‐Shah model. The local criterion energy is then integrated with a global region measure, which is based on intensity difference of the true signal. The energy is minimized in a variational level set formulation with a regularity term, thus avoiding the expensive computation of the level set reinitialization and keeping the curve close to the signal distance function. Experiment results on biological images show desirable performance and demonstrate the effectiveness of the proposed algorithm.
Epitaxy on surfaces vicinal to Si(001). I. Diffusion of silicon adatoms over the terraces.

We have studied the migration of silicon adatoms over the flat, reconstructed Si(001) surface with molecular-dynamics techniques, using the empirical Stillinger-Weber potential. We have mapped out the potential-energy surface seen by a single adatom over the surface. The binding of an adatom to the Si(001) surface was found to be quite strong\char22{}its value of 3.0 eV is a sizable fraction of 4.33 eV, the energy of a bulk silicon atom. In agreement with other studies, we find that the diffusion of single adatoms over the surface is anisotropic, with the fast diffusion direction being along the dimer rows. We carried out a direct measurement of a diffusion coefficient by studying the motion of individual adatoms over a time period of 300 ps. The motion of individual adatoms conforms quite well to the underlying energy surface. However, we did observe frequent exchange events between adatoms and atoms near the surface, which gives an additional contribution to the rate of diffusion. In addition, we mapped out the potential-energy surfaces seen by a silicon adatom over Si(001) surfaces that were under compressive and tensile strain. In these situations, the binding was found to increase or decrease depending upon whether the surface was compressed or expanded. Little change was observed in the anisotropy of the diffusion constant. We also looked at diffusion over the Si(001) surface in which the compression is either along or perpendicular to the dimer axis. Compression of the surface perpendicular to the dimer axis decreases the diffusional anisotropy, while compression of the surface parallel to the dimer axis increases the diffusional anisotropy.
Giant Cells of Escherichia coli: a Morphological Study

Bacterial growth without division was observed in a giant cell-producing strain of Escherichia coli K-12. Giant cell production is controlled by the lon− (failure of cell division after irradiation) and mon− (formation of irregularly shaped cells) genes. Irradiation of a lon−mon− strain (P678-A4) with low doses of ultraviolet or ionizing radiation results in the production of large, amorphous giant cells with 500 to 1,000 times the volume of the nonirradiated parents. The concentration of NaCl in the growth medium was found to influence irradiated-cell morphology. Low concentrations (0.2% NaCl) resulted in elongated cells, whereas spherical giant cells were produced in the presence of high salt (1% NaCl) concentrations. Thin-section electron microscopy revealed an extensive network of intracellular membranes forming vacuoles, vesicles, and cisternae. These structures bear a striking resemblance to the rough and smooth membranes (endoplasmic reticulum, Golgi complex, vacuoles, etc.) found in eucaryotic cells.
Summarization of tweets and Named Entity Recognition from tweet segmentation

Twitter is a source of sharing and communicate recent information, ensuing into huge size of records produces every day. Even though, a various applications of Natural Language Processing and Information Retrieval go through rigorously from an erroneous and tiny nature of tweets. We thought to implement a framework in support of segmentation of tweet by collection form, called as HybridSeg. During tweet separating with trivial segments, surroundings information is preserved and simply takes out by the downstream application. HybridSeg glance for top segmentation of a tweet through increasing stickiness score of its candidate segment. The stickiness score is explanation the possibility of a segment is express in English (global context and local context). Finally we advise and assess two models to acquire with local context by concerning the term-dependency in a collection of tweets, in the same way. Testing on two tweet data sets give you an idea about tweet segmentation superiority is considerably enhanced by global and local contexts evaluate by use of global context simply. Assessment and relationship, we demonstrate that additional correctness is accomplished in Named Entity Recognition by part-of-speech (POS) tagging of placing segment-based.
Encoding a triangulation as a permutation of its point set

We present algorithms that given a straight edge tri-angulation of n points in the plane encode a triangu-lation as a permutation of the points. A rst algorithm , of rather theoretical interest, realizes the encoding and decoding in O(n) time. We also present a more practical algorithm consuming O(n log n) time. As a byproduct of this work we get a new upper bound on the number of triangulations of planar point sets of at most 2 8:2n+O(log n) .
Study on Transmission Characteristics of Carbon Nanotube Through Silicon Via Interconnect

In this letter, the Resistance Inductance Capacitance Conductance (RLCG) parameters of carbon nanotube through silicon via (CNT-TSV) are modeled and a transmission line (TL) model is established through ABCD matrix. The impact of their geometrical and material parameters on the TSV transmission characteristics is analyzed over a wideband of frequency using the proposed model. An optimization methodology using air gap insulator is proposed to improve the transmission performance. SPICE results show that a 30.83% reduction in insertion loss and a 40.72% increase in eye open area, respectively.
Time to First Interictal Epileptiform Discharge in Extended Recording EEGs

Summary: The presence of interictal epileptiform discharges (IEDs) in the outpatient interictal EEG can provide evidence for a diagnosis of epilepsy and support for a specific epilepsy syndrome. However, there is variation in the duration of outpatient EEGs, and prolonged EEGs may have a higher yield for IEDs. The authors retrospectively reviewed 172 routine, extended, outpatient EEGs of at least 60 minutes duration in adults to determine the time to the first IED. The mean duration was 187 minutes. Twenty-six percent captured IEDs. The initial IED occurred in the first 20 minutes in 53% and after 20 minutes in 47%. The mean time to the first IED was 32.8 minutes with a range of 1 to 216 minutes and a standard deviation of 48.2 minutes. Results were skewed to the right (skew 2.22) with a median time to the first IED of 10 minutes. There was a longer time to the first IED in temporal epileptiform discharges compared with generalized discharges.
Power Management for Closed-Source Interactive Games on Mobile Devices

On mobile devices games account for the class of most popular, but as well most power hungry applications. This thesis targets to reduce the processor's power consumption while games are being played. The developed power manager predicts the game's future computing requirements and efficiently selects the clock frequency that guarantees optimal power savings and maintains the user experience. The approach, which is applicable even to closed-source games, achieves savings of up to 43.2% compared to Android's default power manager.
Altruism or Cooperation in Captive Chimpanzees, Pan troglodytes ?

The full extent to which non-human primates, including chimpanzees, cooperate with one another is widely debated [see Silk, 2005]. Accounts typically focus on cooperative hunting and intraspecific aggression [Boesch, 2003] or food sharing [Bethell et al., 2000], and the levels at which cooperative behaviours can be explained are numerous [e.g. Connor, 1995]. It is, therefore, important to document possible occurrences of such behaviours when they are observed, especially when these behaviours are displayed under more unusual circumstances. Here we report an event that occurred predominantly between an infant and adult chimpanzee and discuss this in terms of the competing theories underlying the evolution of cooperative behaviour (defined as an interaction that results in a net benefit to both parties [Trivers, 1985]) among social primates.
