Callous-Unemotional Traits, Impulsivity, and Emotional Processing in Adolescents With Antisocial Behavior Problems

Examined the emotional reactivity of adolescents with antisocial behavior problems using a lexical decision paradigm. Evidence from adult forensic samples indicates that psychopathic traits are associated with abnormalities in the processing of emotional stimuli. In an attempt to extend these findings earlier in development, this association was tested in a sample of adolescents (mean age = 16.01; SD = 1.32) referred to a diversion program for delinquent behavior. Emotional processing was assessed by comparing recognition time for emotional words, both positive and negative, to recognition time for nonemotional words. Consistent with adult findings, the callous-unemotional (CU) dimension of psychopathy was associated with slower reaction times to negative words. In contrast, problems of impulse control were associated with faster recognition times for negative emotional words. These findings suggest that different patterns of emotional reactivity may characterize distinct subgroups of youth with antisocial behavior problems.
Entropy Production

Entropy, as defined by Clausius, is the true cornerstone of eq uilibrium thermodynamics. Its statistical interpretation by Boltzmann is the key to our microscopic understand ing of equilibrium. Since then many other concepts of entropy have appeared in physics and mathematics but none of th m has significantly contributed to our understanding of nonequilibrium. However, a notion of entropy pr oduction (rate) has emerged from recent developments in classical and quantum statistical mechanics of nonequil ibri m steady states. Taking this notion seriously, it does not seems possible to define the entropy of a nonequilibrium s teady states [R3]. As argued in [G], if such an entropy exists then it is most likely to take the value −∞ because a system in such a state loses entropy at a constant rate. The purpose of this article is to introduce the notion of entr opy production for nonequilibrium steady states of a small quantum system in contact with thermal reservoirs. W e shall make free use of the concepts and notation of [NESS in quantum statistical mechanics].
PARP inhibition versus PARP-1 silencing: different outcomes in terms of single-strand break repair and radiation susceptibility

The consequences of PARP-1 disruption or inhibition on DNA single-strand break repair (SSBR) and radio-induced lethality were determined in synchronized, isogenic HeLa cells stably silenced or not for poly(ADP-ribose) polymerase-1 (PARP-1) (PARP-1KD) or XRCC1 (XRCC1KD). PARP-1 inhibition prevented XRCC1-YFP recruitment at sites of 405 nm laser micro irradiation, slowed SSBR 10-fold and triggered the accumulation of large persistent foci of GFP-PARP-1 and GFP-PCNA at photo damaged sites. These aggregates are presumed to hinder the recruitment of other effectors of the base excision repair (BER) pathway. PARP-1 silencing also prevented XRCC1-YFP recruitment but did not lengthen the lifetime of GFP-PCNA foci. Moreover, PARP-1KD and XRCC1KD cells in S phase completed SSBR as rapidly as controls, while SSBR was delayed in G1. Taken together, the data demonstrate that a PARP-1- and XRCC1-independent SSBR pathway operates when the short patch repair branch of the BER is deficient. Long patch repair is the likely mechanism, as GFP-PCNA recruitment at photo-damaged sites was normal in PARP-1KD cells. PARP-1 silencing elicited hyper-radiosensitivity, while radiosensitization by a PARP inhibitor reportedly occurs only in those cells treated in S phase. PARP-1 inhibition and deletion thus have different outcomes in terms of SSBR and radiosensitivity.
INFLUENCE OF CUSTOMER SATISFACTION ON LOYALTY: A STUDY ON MOBILE TELECOMMUNICATION INDUSTRY

The mobile telecommunication companies uphold their service quality and change their marketing core strategies to retain their existing customers by enhancing and optimizing the customer loyalty. Therefore, it becomes significant for telecom companies to identify factors of services that influence customer loyalty and in turn creates loyal customers by satisfying them. This present study aims to explore the influence of customer satisfaction on customer loyalty in the context of Bangladesh. This study focused on six factors such as communication, price structure, value-added service, convenience, sales-promotions and customer service. Both primary and secondary information were collected to test the pre-set hypotheses. Descriptive statistics and simple linear regression were employed to analyze the data. Result shows that five factors: communication, price structure, value-added services, convenience and customer service/care have positive correlations with customer loyalty.
Simplified Stochastic Feedforward Neural Networks

It has been believed that stochastic feedforward neural networks (SFNNs) have several advantages beyond deterministic deep neural networks (DNNs): they have more expressive power allowing multi-modal mappings and regularize better due to their stochastic nature. However, training large-scale SFNN is notoriously harder. In this paper, we aim at developing efficient training methods for SFNN, in particular using known architectures and pre-trained parameters of DNN. To this end, we propose a new intermediate stochastic model, called Simplified-SFNN, which can be built upon any baseline DNNand approximates certain SFNN by simplifying its upper latent units above stochastic ones. The main novelty of our approach is in establishing the connection between three models, i.e., DNN->Simplified-SFNN->SFNN, which naturally leads to an efficient training procedure of the stochastic models utilizing pre-trained parameters of DNN. Using several popular DNNs, we show how they can be effectively transferred to the corresponding stochastic models for both multi-modal and classification tasks on MNIST, TFD, CASIA, CIFAR-10, CIFAR-100 and SVHN datasets. In particular, we train a stochastic model of 28 layers and 36 million parameters, where training such a large-scale stochastic network is significantly challenging without using Simplified-SFNN
The effects of Tai Chi on waist circumference and blood pressure in the elderly

[Purpose] The purpose of this study was to investigate the effects of Tai Chi on waist circumference and blood pressure in the elderly. The present study used a nonequivalent control group pretest-posttest design. [Subjects and Methods] Sixty-eight elderly individuals residing in J city were divided into 2 groups: 34 in the experimental group, who received Tai Chi training for 6 weeks, and 34 in the control group, who did not receive Tai Chi training. Simplified Yang style 24-form Tai Chi was used as the intervention, which was conducted for 60 minutes per session, 5 sessions per week, for a total of 6 weeks. In each session, subjects in the experimental group conducted 10 minutes of warm-up exercises, 45 minutes of Tai Chi, and 5 minutes of cool-down exercises. Waist circumference and blood pressure were measured before and after the 6-week intervention. [Results] Waist circumference and blood pressure decreased significantly after the 6-week intervention in the experimental group compared with the control group. [Conclusion] Tai Chi can be used as an effective intervention to improve waist circumference and blood pressure in the elderly.
Mukai implies McKay: the McKay correspondence as an equivalence of derived categories

Let G be a finite group of automorphisms of a nonsingular complex threefold M such that the canonical bundle omega_M is locally trivial as a G-sheaf. We prove that the Hilbert scheme Y=GHilb M parametrising G-clusters in M is a crepant resolution of X=M/G and that there is a derived equivalence (Fourier- Mukai transform) between coherent sheaves on Y and coherent G-sheaves on M. This identifies the K theory of Y with the equivariant K theory of M, and thus generalises the classical McKay correspondence. Some higher dimensional extensions are possible.
The Logic of Framing The Framing Effect as a Non-Monotonic Decision Process of Path Dependence MSc Thesis ( Afstudeerscriptie )

People’s perception can be influenced by framing a message in different ways. For example, decision makers are often favourably disposed towards a medical treatment with a 60% success rate, but less often to one with a 40% failure rate. This suggests that human judgement or decision making is not merely concerned with the content of the message at stake, but also with the way in which this content is presented or ‘framed’. This observation is at odds with standard theories of decision making, which prescribe that human judgement should be invariant under different descriptions of the same fact(s). In this thesis, I explore what framing is, how it makes itself manifest and how the underlying process of human decision making functions. I argue that this decision process is best to be characterised as a non-monotonic process of path dependence, and I present a formal model to make this idea more precise. This model has several advantages over existing models. It is able to provide an elaborate account of framing that is descriptively accurate, more uniform and has a larger scope than existing accounts. Furthermore, it allows for a thoughtful approach to the relationship between the framing effect and human rationality.
Bayesian Analysis of Interference Cancellation for Alamouti Multiplexing

Space-time codes built out of Alamouti components have been adopted in wireless standards such as UMTS, IEEE 802.11n, and IEEE 802.16, where they facilitate higher data rates through multiplexing of parallel data streams and the addition of two or more antennas at the receiver that perform interference cancellation. This correspondence provides new theoretical insight into different algorithms for interference cancellation through a Bayesian analysis that expresses performance as a function of signal-to-noise ratio (SNR) in terms of the ldquoanglesrdquo between different space-time coded data streams.
The effect of ABO blood group on the diagnosis of von Willebrand disease.

In order to firmly establish a normal range for von Willebrand factor antigen (vWF:Ag), we determined plasma vWF:Ag concentrations in 1,117 volunteer blood donors by quantitative immunoelectrophoresis. The presence of the ABO blood group has a significant influence on vWF:Ag values; individuals with blood group O had the lowest mean vWF:Ag level (74.8 U/dL), followed by group A (105.9 U/dL), then group B (116.9 U/dL), and finally group AB (123.3 U/dL). Multiple regression analysis revealed that age significantly correlated with vWF:Ag levels in each blood group. We then performed reverse ABO typing on stored plasma from 142 patients with the diagnosis of von Willebrand disease (vWd). Of 114 patients with type I vWd, blood group O was found in 88 (77%), group A in 21 (18%), group B in 5 (4%), and group AB in none (0%), whereas the frequency of these blood groups in the normal population is significantly different (45%, 45%, 7% and 3%, respectively) (P less than .001). Patients with type II or III vWd had ABO blood group frequencies that were not different from the expected distribution. There may be a subset of symptomatic vWd patients with decreased concentrations of structurally normal vWf (vWd, type I) on the basis of blood group O. Some individuals of blood group AB with a genetic defect of vWF may have the diagnosis overlooked because vWF levels are elevated due to blood type.
Auditing Search Engines for Differential Satisfaction Across Demographics

Many online services, such as search engines, social media platforms, and digital marketplaces, are advertised as being available to any user, regardless of their age, gender, or other demographic factors. However, there are growing concerns that these services may systematically underserve some groups of users. In this paper, we present a framework for internally auditing such services for differences in user satisfaction across demographic groups, using search engines as a case study. We first explain the pitfalls of naively comparing the behavioral metrics that are commonly used to evaluate search engines. We then propose three methods for measuring latent differences in user satisfaction from observed differences in evaluation metrics. To develop these methods, we drew on ideas from the causal inference literature and the multilevel modeling literature. Our framework is broadly applicable to other online services, and provides general insight into interpreting their evaluation metrics.
Endovascular Stent-Graft Placement for Vascular Failure of the Thoracic Aorta

It still remains undetermined whether endovascular stent-graft placement (ESGP) is the optimal initial treatment for elective cases of thoracic aortic disease because of unknown long-term results. However, it is also recognized that ESGP contributes to better outcome as an initial treatment for aortic emergency, such as rupture, aortic injury, and complicated acute type B aortic dissection. Despite the fact that most patients are elderly, early mortality rates of ESGP are reportedly around 10% in cases of ruptured degenerative thoracic aortic aneurysm. Postoperative morbidity is also superior in ESGP compared with conventional open repair. Postoperative paraplegia has rarely occurred with ESGP. In cases of blunt aortic injury (BAI), other complications may also be present because of other serious injuries. ESGP has changed the surgical strategy for BAI and partially resolved some of the clinical dilemmas. Early mortality rate is almost zero when a stent graft can be placed before re-rupture. While BAI is a very good indication for ESGP, young patients need careful management and attention because of the unknown long-term outcome. In cases of complicated acute type B aortic dissection, the two main determinants of death, shock from rupture and visceral ischemia, could be managed by ESGP with or without conventional endovascular interventions. Recent reports disclosed less than 10% early mortality with ESGP for complicated acute aortic dissection. Even if the possibility of endotension remains, ESPG seems to be beneficial for these critical patients as the preferable initial treatment. The importance of close follow-up should be stressed to avoid some devastating late complications following ESGP.
Inhibition of Kainate Receptors Reduces the Frequency of Hippocampal Theta Oscillations

We investigated the role of kainate receptors in the generation of theta oscillations using (S)-1-(2-amino-2-carboxyethyl)-3-(2-carboxythiophene-3-yl-methyl)pyrimidine-2,4-dione (UBP304), a novel, potent and highly selective antagonist of GLUK5-containing kainate receptors. EEG and single-unit recordings were made from the dorsal hippocampus of awake, freely moving rats trained to forage for food. Bilateral intracerebroventricular injections of UBP304 (2.0 μl, two times; 2.08 mm) caused a clear (∼25%) reduction in theta frequency that was dissociable from behavioral effects of the drug. The locations of firing fields of principal cells in the hippocampal formation were generally preserved, but both field firing rates and the precision of field organization decreased. UBP304 lowered the frequency of the theta modulation of hippocampal interneuron discharge, accurately matching the reduced frequency of the theta field oscillation. UBP308 [(R)-1-(2-amino-2-carboxyethyl)-3-(2-carboxythiophene-3-yl-methyl)pyrimidine-2,4-dione], the inactive enantiomer of UBP304, caused none of these effects. Our results suggest that GLUK5 receptors have an important role in modulating theta activity. In addition, the effects on cellular responses provide both insight into the mechanisms of theta pacing, and useful information for models of temporal coding.
Identifying Product Features from Customer Reviews using Lexical Concordance

Automatic extraction of features from unstructured text is one of the challenging problems of Opinion Mining. The trend of getting products and services reputation from online resources such as web blogs and customer feedback is increasing day by day. Therefore efficient system is required to automatically extract products features and the opinion of consumers about all aspects of the products. In this study our focus is on extraction of product features from customer reviews. We have proposed a concordance based technique for automatic extraction of features of product from customer reviews. In our proposed technique we extract patterns of lexical terms using concordance for candidate features extraction and identify features by grouping. The proposed grouping algorithm is used to remove irrelevant features. We conducted experiments on different products reviews and compared our results with existing methods. From empirical results we proved the validity of the proposed method.
Incidence of neurosensory deficits following surgical removal of mandibular third molars: a prospective clinical study

Background: The aim of this prospective study was to determine the incidences of inferior alveolar nerve and lingual nerve deficit following surgical removal of impacted mandibular third molars and to evaluate the risk factors responsible for these postoperative neurosensory deficits.Methods: A total of 80 patients who reported to department of oral and maxillofacial surgery, Meenakshi Ammal Dental College, Chennai, Tamil Nadu, India requiring surgical removal of impacted mandibular third molar were included in this cross-sectional study. Standard surgical procedure was performed. All patients were reassessed one week post-surgery. Subjectively reported altered sensations were recorded and objective assessments were performed with light touch test, two-point discrimination threshold and pin-pick pain threshold. The collected data was analyzed using the chi square test to find out any clinical relevance.Results: There was no inferior alveolar nerve related neurosensory deficits and 6 (7.5%) resulted in lingual nerve related neurosensory deficits. The incidence of LN deficit for mesioangular, horizontal, distoangular was 1.3%, 3.8% and 2.5% respectively. Type of impaction assumed a mild statistical significance (p = 0.050). Conclusions: This study highlights the importance of careful preoperative clinical and radiographic assessment of patients where third molar surgery is planned. The surgical technique of third molar removal is also likely to have great impact on the outcome.
Driving Behavior and Simulator Sickness While Driving the Vehicle in the Loop: Validation of Longitudinal Driving Behavior

The Vehicle in the Loop (VIL) is a simulator, which combines real driving experience with the replicability and safety of simulators. In the VIL test setup a real test vehicle is combined with a virtual testing environment which is displayed to the user via a head-mounted display (HMD). In theory, this simulation concept renders the VIL uniquely suited to the development and evaluation of numerous automotive applications, including driver assistance systems. Aiming to assess the extent to which the VIL elicits realistic driving responses, a validation study was performed. In this first validation study the focus was on longitudinal driving behavior. 44 participants performed five common traffic maneuvers in reality and the VIL setup. Simulator sickness was assessed with the simulator sickness questionnaire (SSQ). Descriptive and inferential analyses of the data showed that the VIL achieves relative validity concerning brake pressure and reaction times and absolute validity concerning the steering angle. However, subjects showed longer reaction times and accelerated more smoothly while driving the VIL. One possible explanation for these results could be the presence of simulator sickness. Overall, the study indicates that the VIL represents a suitable testing method for the evaluation and development of driver assistance systems. The study also provided clear indications for the future development of the VIL.
Morley’s Trisector Theorem

Abstract Morley’s trisector theorem states that “The points of intersection of the adjacent trisectors of the angles of any triangle are the vertices of an equilateral triangle” [10]. There are many proofs of Morley’s trisector theorem [12, 16, 9, 13, 8, 20, 3, 18]. We follow the proof given by A. Letac in [15].
Medication management in people with Parkinson's disease during surgical admissions

Background Patients with Parkinson's disease (PD) may experience problems in hospital, with their medication being withheld or inappropriate medication being prescribed. Since surgical admissions present particular risks, the authors examined the management of patients with PD on surgical wards. Methods All patients with PD admitted to surgical departments in Aberdeen Royal Infirmary during an 18-month period were identified. Medical and nursing notes were reviewed retrospectively, and drug prescription and administration were studied in detail. All documented complications were recorded. Results 59 surgical admissions (51 receiving PD medication, median duration 6 days) were studied. 71% had missed doses of PD medication, with 34% missing over 10% of prescribed doses. Values were similar for levodopa and agonists. Overall, 12% of all prescribed PD medication was missed (mean 0.7 missed doses per patient per day). No reason for missed doses was recorded in 64% of cases, while inappropriate reasons included ‘out of stock’ (12%) and ‘nil by mouth’ (8%). Centrally acting antidopaminergic drugs (mainly antiemetics) were prescribed in 41% of cases, and administered in 22%. Complications, most commonly neuropsychiatric, were documented in 69% of non-day-case admissions. Conclusion Poor prescribing and incomplete drug administration are common in patients with PD on surgical wards. Measures to improve management are identified.
Clinical outcomes in surgical and non-surgical management of hepatic portal venous gas

Backgrounds/Aims Hepatic portal venous gas (HPVG) is a rare condition, with poor prognosis and a mortality rate of up to 75%. Indications for surgical and non-surgical management of HPVG including associated complications and mortality remain to be clarified. Methods From January 2008 to December 2014, 18 patients with HPVG diagnosed through abdominal computed tomography (CT) imaging were retrospectively identified. Clinical symptoms, laboratory data, underlying diseases, treatment, and mortality rate were analyzed. Patients were classified into 2 groups: surgical management recommended (SR, n=10) and conservative management (CM, n=8). The SR group was further subdivided into patients who underwent surgical management (SM-SR, n=5) and those who were managed conservatively (NS-SR, n=5). Results Conditions underlying HPVG included mesenteric ischemia (38.9%), intestinal obstruction (22.2%), enteritis (22.2%), duodenal ulcer perforation (5.6%), necrotizing pancreatitis (5.6%), and diverticulitis (5.6%). In terms of mortality, 2 patients (40%) died in the SM-SR group, 1 (12.5%) in the CM group, and 100% in the NS-SR group. Higher scores from Acute Physiology and Chronic Health Evaluation (APACHE) II predicted the mortality rates of the NS-SR and CM groups. Conclusions Identification of HPVG requires careful consideration for surgical management. If surgical management is indicated, prompt laparotomy should be performed. However, even in the non-surgical management condition, aggressive laparotomy can improve survival rates for patients with high APACHE II scores.
