ITERATIVELY SOLVING LINEAR INVERSE PROBLEMS UNDER GENERAL CONVEX CONSTRAINTS

We consider linear inverse problems where the solution is assumed to fulfill some general homogeneous convex constraint. We develop an algorithm that amounts to a projected Landweber iteration and that provides and iterative approach to the solution of this inverse problem. For relatively moderate assumptions on the constraint we can always prove weak convergence of the iterative scheme. In certain cases, i.e. for special families of convex constraints, weak convergence implies norm convergence. The presented approach covers a wide range of problems, e.g. Besov– or BV–restoration for which we present also numerical experiments in the context of image processing.
Fast algorithm for VQ codebook design

The paper presents a fast codebook training algorithm for vector quantisation. It uses an elimination rule, based on triangular inequality criteria, as well as the partial distortion elimination method, to relieve the computational burden of a conventional codebook training algorithm, including a binary codeword splitting algorithm for the initial codebook and the LBG recursive algorithm. Over 95% savings in both multiplication and addition operations were achieved in the simulation of a VQ codebook training of a ‘Lena’ image using 16-dimensional vectors.
Acute Medical Costs of Fluoxetine versus Tricyclic Antidepressants

Summary Despite demonstrated differences in toxicity profiles between tricyclic antidepressants (TCAs) and selective serotonin (5-hydroxytryptamine; S-HT) reuptake inhibitors (SSRIs), no studies have examined hospital costs associated with acute antidepressant overdoses. Given the high incidence of such overdoses, it is important to examine treatment patterns and associated costs. This prospective, multicentre cohort study compared the hospital and physician costs associated with TCA and fluoxetine drug overdoses. Over a 30-month period, 622 consecutive patients with a fluoxetine or TCA overdose presented to the emergency departments. or were admitted to intensive care or medical units. of9 participating medical centres across the US. Inclusion criteria were: ingestion of a single antidepressant (fluoxetine or a TCA), without clinically significant co-ingestants; laboratory confirmation of the overdose; and retrievable hospital bills. Patients were followed until discharge from the emergency department or hospital. Hospital and physician charges were collected from billing data. Hospital charges were adjusted using Health Care Financing Administration cost: charge ratios to estimate costs; physician charges were adjusted to estimate costs. Patient demographic and clinical data were prospectively gathered during the course of medical treatment. Clinical data recorded included level of consciousness, cardiopulmonary complications. vital sign or ECG abnormalities. agitation. seizures, CNS depression and death. 136 patients (121 with TCA overdose and IS with fluoxetine overdose), representing 21.8% of the 622 patients entered, met the inclusion criteria. Mean length of stay varied from 0.73 [± standard error of the mean (SEM) 0.33] days for fluoxetine overdose patients to 3.59 ( SEM 0.48) days for TCA overdose patients (p = 0.038). Mean hospital costs were $US668 for patients with a fluoxetine overdose compared with $US4691 for those with a TCA overdose (p > 0.0001). No significant differences were observed between the TCA and fluoxetine overdose groups with regard to physician costs. Median hospital and physician costs increased from $US3029 to $US4396 from the first IS-month period of the study to the second 15-month period of the study for the TCA overdose group. but decreased from $US881 to $US396 for the fluoxetine overdose group. Patients with fluoxetine overdoses had lower hospital and total medical costs compared with patients with TCA overdoses. There was some evidence supporting a reduction in the medical costs of treating fluoxetine overdoses over the 3D-month study period.
External root resorption of the second molar associated with mesially and horizontally impacted mandibular third molar: evidence from cone beam computed tomography

The aim of the present study was to assess the incidence and risk factors of ERR in second molars with mesially and horizontally impacted mandibular third molars using cone beam computed tomography (CBCT) images from patients in a Chinese tertiary referral hospital. A total number of 216 patients with 362 mesially and horizontally impacted mandibular third molars who were treated at our institution from 2014 to 2015 was retrospectively included. The ERR in second molars was identified on CBCT multiplanar images. The associations between incidence of ERR and multiple clinical parameters were statistically analyzed by Chi-square test. Moreover, the risk factors for ERR in second molars were further assessed by multivariate regression analysis. The overall incidence of ERR in second molars was 20.17 % (73/362) as detected on CBCT images. The presence of ERR significantly associated with patients age and impaction depth of mandibular third molars. However, no significant relationship was found between ERR severity and impaction depth or ERR location. Multivariate regression analyses further revealed age over 35 years and impaction depth as important risk factors affecting the ERR incidence caused by mesial and horizontal impaction of mandibular third molar. ERR in second molar resulted from mesially and horizontally impacted mandibular third molar is not very rare and can be reliably identified via CBCT scan. Given the possibility of ERR associated with third molar impaction, the prophylactic removal of these impacted teeth could be considered especially for those patients with over 35 years and mesially and horizontally impacted teeth.
Multi-objectivization of short-term unit commitment under uncertainty using evolutionary algorithm

The short-term unit commitment problem is traditionally solved as a single-objective optimization problem with system operation cost as the only objective. This paper presents multi-objectivization of the short-term unit commitment problem in uncertain environment by considering reliability as an additional objective along with the economic objective. The uncertainties occurring due to unit outage and load forecast error are incorporated using loss of load probability (LOLP) and expected unserved energy (EUE) reliability indices. The multi-objectivized unit commitment problem in uncertain environment is solved using our earlier proposed multi-objective evolutionary algorithm [1]. Simulations are performed on a test system of 26 thermal generating units and the results obtained are benchmarked against the study [2] where the unit commitment problem was solved as a reliability-constrained single-objective optimization problem. The simulation results demonstrate that the proposed multi-objectivized approach can find solutions with considerably lower cost than those obtained in the benchmark. Further, the efficiency and consistency of the proposed algorithm for multi-objectivized unit commitment problem is demonstrated by quantitative performance assessment using hypervolume indicator.
Simple and Phrasal Implicatives

This paper complements a series of works on implicative verbs such as manage to and fail to. It extends the description of simple implicative verbs to phrasal implicatives as take the time to and waste the chance to. It shows that the implicative signatures of over 300 verb-noun collocations depend both on the semantic type of the verb and the semantic type of the noun in a systematic way.
A Passive Circulator for RFID Application with High Isolation using a Directional Coupler

In this paper, a newly invented circulator for T/R switch of UHF radio-frequency identification (RFID) application is proposed to overcome TX-to-RX leakage problem. A microstrip coupled-line directional coupler is used for this passive circulator and the isolation characteristic is drastically improved not by complex method such as compensating phase velocity, but by considering both directional coupler itself and imperfect input impedance of the employed antenna. The measurement result of the proposed circulator using modified microstrip coupled-line directional coupler with employed antenna shows excellent TX-to-RX leakage suppression in the 860 MHz - 960 MHz, more than 45 dB enhancement at the center frequency compared to the conventional coupler. Experimental verification using RFID system is also performed to prove the validity of the proposed circulator
Associations between sounds and actions in early auditory cortex of nonhuman primates

An individual may need to take different actions to the same stimulus in different situations to achieve a given goal. The selection of the appropriate action hinges on the previously learned associations between stimuli, actions, and outcomes in the situations. Here, using a go/no-go paradigm and a symmetrical reward, we show that early auditory cortex of nonhuman primates represents such associations, in both the spiking activity and the local field potentials. Sound-evoked neuronal responses changed with sensorimotor associations shortly after sound onset, and the neuronal responses were largest when the sound signaled that a no-go response was required in a trial to obtain a reward. Our findings suggest that the association process takes place in the auditory system and does not necessarily rely on association cortex. Thus, auditory cortex may contribute to a rapid selection of the appropriate motor responses to sounds during goal-directed behavior.
Detection of Norovirus genogroup I and II by multiplex real-time RT- PCR using a 3'-minor groove binder-DNA probe

BACKGROUND
Due to an increasing number of norovirus infections in the last years rapid, specific, and sensitive diagnostic tools are needed. Reverse transcriptase-polymerase chain reactions (RT-PCR) have become the methods of choice. To minimize the working time and the risk of carryover contamination during the multi-step procedure of PCR the multiplex real-time RT-PCR for the simultaneous detection of genogroup I (GI) and II (GII) offers advantages for the handling of large amounts of clinical specimens.


METHODS
We have developed and evaluated a multiplex one-tube RT-PCR using a combination of optimized GI and GII specific primers located in the junction between ORF1 and ORF2 of the norovirus genome. For the detection of GI samples, a 3'-minor groove binder-DNA probe (GI-MGB-probe) were designed and used for the multiplex real-time PCR.


RESULTS
Comparable results to those of our in-house nested PCR and monoplex real-time-PCR were only obtained using the GI specific MGB-probe. The MGB-probe forms extremely stable duplexes with single-stranded DNA targets, which enabled us to design a shorter probe (length 15 nucleotides) hybridizing to a more conserved part of the GI sequences. 97% of 100 previously norovirus positive specimens (tested by nested PCR and/or monoplex real-time PCR) were detected by the multiplex real-time PCR. A broad dynamic range from 2 x 10(1) to 2 x 10(7) genomic equivalents per assay using plasmid DNA standards for GI and GII were obtained and viral loads between 2.5 x 10(2) and 2 x 10(12) copies per ml stool suspension were detected.


CONCLUSION
The one-tube multiplex RT real-time PCR using a minor groove binder-DNA probe for GI is a fast, specific, sensitive and cost-effective tool for the detection of norovirus infections in both mass outbreaks and sporadic cases and may have also applications in food and environmental testing.
Approximation and Radial-Basis-Function Networks

This paper concerns conditions for the approximation of functions in certain general spaces using radial-basis-function networks. It has been shown in recent papers that certain classes of radial-basis-function networks are broad enough for universal approximation. In this paper these results are considerably extended and sharpened.

Refinement of surface mesh for accurate multiview reconstruction

In this paper we propose a pipeline for accurate 3D reconstruction from multiple images that deals with some of the possible sources of inaccuracy present in the input data. Namely, we address the problem of inaccurate camera calibration by including a method [1] adjusting the camera parameters in a global structure-and-motion problem which is solved with a depth map representation that is suitable to large scenes. Secondly, we take the triangular mesh and calibration improved by the global method in the first phase to refine the surface both geometrically and radiometrically. Here we propose surface energy which combines photo consistency with contour matching and minimize it with a gradient method. Our main contribution lies in effective computation of the gradient that naturally balances weight between regularizing and data terms by employing scale space approach to find the correct local minimum. The results are demonstrated on standard high-resolution datasets and a complex outdoor scene.

This course will look at three key areas: how social identity is portrayed online; our changing social networks and the technologies that support them; and the role of pseudonymity in supporting privacy.
Effect of Mindfulness-Based Stress Reduction Training on Health Care Worker Safety: A Randomized Waitlist Controlled Trial.

OBJECTIVE
The study assessed the impact of mindfulness training on occupational safety of hospital health care workers.


METHODS
The study used a randomized waitlist-controlled trial design to test the effect of an 8-week mindfulness-based stress reduction (MBSR) course on self-reported health care worker safety outcomes, measured at baseline, postintervention, and 6 months later.


RESULTS
Twenty-three hospital health care workers participated in the study (11 in immediate intervention group; 12 in waitlist control group). The MBSR training decreased workplace cognitive failures (F [1, 20] = 7.44, P = 0.013, (Equation is included in full-text article.)) and increased safety compliance behaviors (F [1, 20] = 7.79, P = 0.011, (Equation is included in full-text article.)) among hospital health care workers. Effects were stable 6 months following the training. The MBSR intervention did not significantly affect participants' promotion of safety in the workplace (F [1, 20] = 0.40, P = 0.54, (Equation is included in full-text article.)).


CONCLUSIONS
Mindfulness training may potentially decrease occupational injuries of health care workers.
Combination of Alpha Lipoic Acid and Superoxide Dismutase Leads to Physiological and Symptomatic Improvements in Diabetic Neuropathy

BACKGROUND AND OBJECTIVE
The management of diabetic neuropathy is still a challenge for physicians. The aim of this study was to assess the efficacy of a new combination of alpha lipoic acid and superoxide dismutase for the treatment of diabetic neuropathy.


METHODS
The setting of this study was ambulatory (outpatient) care. A prospective, non-randomized, open-label study was conducted in 50 patients with diabetes mellitus and with a deficit in both motor and sensory nerve conduction. Treatment was with a new combination of alpha lipoic acid and superoxide dismutase (ALA600SOD®) for 4 months. Electroneurographic parameters and perceived pain were assessed at baseline and after treatment.


RESULTS
After 4 months of treatment, patients significantly (p < 0.001) improved their electroneurographic parameters and their perception of pain. Best improvements were observed in sensory nerve conduction.


CONCLUSION
The combination of two powerful antioxidant agents leads to improvement in both subjective and objective parameters in patients with diabetic neuropathy. New profitable directions for investigations are opened for a non-invasive treatment of diabetic neuropathy in the future.
Mobile Edge Computing: Progress and Challenges

Mobile Edge Computing (MEC) provides mobile and cloud computing capabilities within the access network, and aims to unite the telco and IT at the mobile network edge. This paper presents an investigation on the progress of MEC, and proposes a platform, named WiCloud, to provide edge networking, proximate computing and data acquisition for innovative services. Furthermore, the open challenges that must be addressed before the commercial deployment of MEC are discussed.
Guiding students through reflective practice - The preceptors experiences. A qualitative descriptive study.

BACKGROUND
Nurse Education in Ireland has experienced a significant change over the last 10 years. As a consequence staff nurses must be prepared to support student learning and enable student learners obtain an optimum educational outcome, thereby enriching the students' clinical placement. 'Reflective time' has been included in the rostered year to enhance the consolidation of theory and practice. The nurse preceptor can facilitate students to reflect on their practice through guided reflection. This study presents the experiences of seven preceptors towards guiding student nurses through reflective practice in the clinical practice area.


METHODOLOGY
A qualitative descriptive research methodology was chosen to research this phenomenon. Semi-structured qualitative interviews were undertaken with a purposive sample of seven student nurse preceptors. All the interviews were transcribed verbatim and analysed using Burnard's [Burnard, P., 1991. A method of analysing interview transcripts in qualitative research. Nurse Education Today, 11(6), 461-466] 14-stage method of thematic analysis.


RESULTS
Analysis of the data revealed that preceptors had little or no experience of using guided reflection within the preceptorship process. Factors, which contributed to these findings included the training and development of preceptors, the critical relationships within the preceptorship process, and the preceptors' experiences of reflection in the past and present, not withstanding the anticipated future benefits of using guided reflection to aid student learning.


CONCLUSION
Guided reflection is a relatively new concept in Irish nursing with this study generating data on seven preceptors' experiences of using guided reflection in the preceptorship process. The study caused the participants to deeply reflect on their own knowledge and understanding of guided reflection and how guided reflection has the potential to facilitate the development and maintenance of the student nurse/preceptor relationship.
A systematic review of dietary protein during caloric restriction in resistance trained lean athletes: a case for higher intakes.

UNLABELLED
Caloric restriction occurs when athletes attempt to reduce body fat or make weight. There is evidence that protein needs increase when athletes restrict calories or have low body fat.


PURPOSE
The aims of this review were to evaluate the effects of dietary protein on body composition in energy-restricted resistance-trained athletes and to provide protein recommendations for these athletes.


METHODS
Database searches were performed from earliest record to July 2013 using the terms protein, and intake, or diet, and weight, or train, or restrict, or energy, or strength, and athlete. Studies (N = 6) needed to use adult (≥ 18 yrs), energy-restricted, resistance-trained (> 6 months) humans of lower body fat (males ≤ 23% and females ≤ 35%) performing resistance training. Protein intake, fat free mass (FFM) and body fat had to be reported.


RESULTS
Body fat percentage decreased (0.5-6.6%) in all study groups (N = 13) and FFM decreased (0.3-2.7kg) in nine of 13. Six groups gained, did not lose, or lost nonsignificant amounts of FFM. Five out of these six groups were among the highest in body fat, lowest in caloric restriction, or underwent novel resistance training stimuli. However, the one group that was not high in body fat that underwent substantial caloric restriction, without novel training stimuli, consumed the highest protein intake out of all the groups in this review (2.5-2.6g/kg).


CONCLUSIONS
Protein needs for energy-restricted resistance-trained athletes are likely 2.3-3.1g/kg of FFM scaled upwards with severity of caloric restriction and leanness.
Implant and long-term evaluation of atrial signal amplification in a single-lead ICD.

BACKGROUND
In patients without clinical indications for pacing the use of a single-lead implantable cardioverter defibrillator (ICD) implementing atrial sensing capability with proper signal amplification management may represent a useful therapeutic option, combining the positive features of both single and dual-chamber devices. The aim of the study was to evaluate the atrial signal amplification and its long-term stability in a single-lead ICD system adding atrial sensing to a standard single-chamber ICD.


METHODS
P-wave amplitudes were collected and compared at implant both with a conventional external device ("unfiltered" P wave) and telemetrically with the implanted ICD ("filtered" P wave). Filtered/unfiltered P-wave ratio (amplification factor, AmF) was evaluated at implant and during follow-up.


RESULTS
In 43 enrolled patients (38 men, age 64 ± 16 years), the mean filtered P wave at implant was significantly higher than the unfiltered P wave (3.85 ± 0.81 mV vs 2.0 ± 1.49 mV; P < 10(-11) ), with a mean AmF value of 2.77 ± 1.62. In seven patients with atrial fibrillation at implant, the AmF was higher (4.62 ± 1.94) than in patients in sinus rhythm (2.41 ± 1.30; P < 0.001). A significant linear correlation was found between the inverse of P wave and the AmF (R = 0.82, P < 0.00001). In 25 patients followed for 384 ± 244 days, atrial undersensing was never documented and AmF did not change from implant (3.19 ± 1.82; P = 0.24), also in different body position and breathing conditions.


CONCLUSIONS
The single-lead ICD system evaluated reliably amplified P-wave amplitudes by a factor of about three, maintaining this performance during the observed follow-up.
