Statistical Matching as a Supplement to Record Linkage: A Valuable Method to Tackle Nonconsent Bias?
Year: 2018

Record linkage has become an important tool for increasing research opportunities in the social sciences. Surveys that perform record linkage to administrative records are often required to obtain informed consent from respondents prior to linkage. A major concern is that nonconsent could introduce biases in analyses based on the linked data. One straightforward strategy to overcome the missing data problem created by nonconsent is to match nonconsenters with statistically similar units in the target administrative database. To assess the effectiveness of statistical matching in this context, we use data from two German panel surveys that have been linked to an administrative database of the German Federal Employment Agency. We evaluate the statistical matching procedure under various artificial nonconsent scenarios and show that the method can be effective in reducing nonconsent biases in marginal distributions, but that biases in multivariate estimates can sometimes be worsened. We discuss the implications of these findings for survey practice and elaborate on some of the practical challenges of implementing the statistical matching procedure in the context of linkage nonconsent. The developed simulation design can act as a roadmap for other statistical agencies considering the proposed approach for their data.
Inactivation of a CRF dependent amygdalofugal pathway reverses addiction like behaviors in alcohol dependent rats
Venue: Nature Communications
Year: 2019

The activation of a neuronal ensemble in the central nucleus of the amygdala (CeA) during alcohol withdrawal has been hypothesized to induce high levels of alcohol drinking in dependent rats. In the present study we describe that the CeA neuronal ensemble that is activated by withdrawal from chronic alcohol exposure contains ~80% corticotropin releasing factor (CRF) neurons and that the optogenetic inactivation of these CeA CRF+ neurons prevents recruitment of the neuronal ensemble, decreases the escalation of alcohol drinking, and decreases the intensity of somatic signs of withdrawal. Optogenetic dissection of the downstream neuronal pathways demonstrates that the reversal of addiction like behaviors is observed after the inhibition of CeA CRF projections to the bed nucleus of the stria terminalis (BNST) and that inhibition of the CRFCeA BNST pathway is mediated by inhibition of the CRF CRF1 system and inhibition of BNST cell firing. These results suggest that the CRFCeA BNST pathway could be targeted for the treatment of excessive drinking in alcohol use disorder.Withdrawal from alcohol activates neurons in the central amygdala (CeA) and increases craving for alcohol. The authors show that these neurons predominantly express CRF and project to the BNST. Inactivation of this pathway reduces the dependence related escalation of alcohol drinking.

The Psychology of Food Cravings: the Role of Food Deprivation
Venue: Current Nutrition Reports
Year: 2020

Dieting is often blamed for causing food cravings. Such diet induced cravings may be mediated by physiological (e.g. nutritional deprivation) or psychological (e.g. ironic effects of food thought suppression) mechanisms. However, this notion is often based on cross sectional findings and, thus, the causal role of food deprivation on food cravings is unclear.  Experimental studies suggest that a short term, selective food deprivation seems to indeed increase cravings for the avoided foods. However, experimental studies also show that food craving can be understood as a conditioned response that, therefore, can also be unlearned. This is supported by intervention studies which indicate that long term energy restriction results in a reduction of food cravings in overweight adults.  Dieting's bad reputation for increasing food cravings is only partially true as the relationship between food restriction and craving is more complex. While short term, selective food deprivation may indeed increase food cravings, long term energy restriction seems to decrease food cravings, suggesting that food deprivation can also facilitate extinction of conditioned food craving responses.
Cervical Pyomyositis A Rare Cause of Cervicalgia Presenting to the Emergency Room
Venue: Canadian Journal of Neurological Sciences Journal Canadien des Sciences Neurologiques
Year: 2020

We are reporting on a 22 year old female, native of Burundi, who presented to the emergency department with a 2 week history of severe bilateral cervico occipital pain and nuchal rigidity. She denied any fever, rashes, neurological deficits, trauma, or recent infections. She was afebrile and hemodynamically stable. Physical examination revealed nuchal swelling, tenderness, and rigidity. There were no lymphadenopathies or focal neurological deficits. Laboratory investigations revealed leukocytosis at 14.4 x 10/L. Serologies for HIV, hepatitis, and syphilis were negative. The patient had been discharged from the emergency department 2 weeks prior with a diagnosis of occipital neuralgia. However, clinical presentation and nuchal rigidity were concerning for an infectious process, and a CT scan was ordered prior to lumbar puncture. Imaging demonstrated evidence of abscess formation in the semispinalis capitis muscles  The abscess was surgically drained and cultures grew Staphylococcus aureus. She rapidly improved on intravenous Ceftriaxione, Vancomycin, and Metronidazole and was discharged on a 2 week course of Cloxacillin. The patient presented with unprovoked cervico occipital pain. An infectious process was not initially suspected as she was afebrile. Classically, patients with pyomyositis present with fever, myalgia, and localized tenderness. Pyomyositis is most frequently seen in tropical regions, occurs in males aged 20 40 years, and most commonly affects lower limb muscles. Pyomyositis can occur in healthy individuals, but often predisposing factors such as immunodeficiency, trauma, injection drug use, concurrent infection, and malnutrition can be identified. Pyomyositis is thought to arise via hematogenous spread and leads to multiple abscess formation. It can be complicated by local destruction of the vertebrae, septic shock, endocarditis, septic emboli, brain abscess, or rhabdomyolysis. S. aureus has been implicated in 75 90% of cases. Early diagnosis and source control via high dose antibiotics plus either percutaneous drainage or surgical intervention are necessary to reduce the risk of morbidity. The initial misdiagnosis as occipital neuralgia underlines the importance of considering this rare condition in the differential diagnosis of cervicalgia in the emergency setting, even in healthy immunocompetent patients.
ON SKEW SYMMETRIC OPERATORS WITH EIGENVALUES
Year: 2015

An operator T on a complex Hilbert space H is called skew symmetric if T can be represented as a skew symmetric matrix relative to some orthonormal basis for H. In this paper, we study skew symmetric operators with eigenvalues. First, we provide an upper triangular operator matrix representation for skew symmetric operators with nonzero eigenvalues. On the other hand, we give a description of certain skew symmetric triangular operators, which is based on the geometric relationship between eigenvectors.
An Image Restoration Method for Outdoor and Its Application to Under Water Using Improved Transmission Map and Airlight Estimation
Year: 2020

Dehazing is an important image restoration technique to remove the presence of Haze from a hazy image. Recent dehazing algorithm is not sufficient to remove Haze from the given outdoor or underwater hazy images. Therefore, an efficient dehazing algorithm is needed for the removal of Haze. Initially, multiple image dehazing methods are used to remove Haze and these dehazing methods have many drawbacks such as, multiple image methods cannot be applied to dynamic scenes and cannot provide results instantly. In order to overcome drawbacks of multiple image dehazing methods, Single image dehazing methods are introduced which are based on some important observations or priors. One such single image dehazing technique is dark channel prior. The thickness of Haze and airlight is estimated using dark channel prior. Guided Filter technique is used to refine the transmission map. But the estimated Haze thickness is inaccurate because of the usage of minimum operator in dark channel prior method. To improve the estimation of Haze thickness, the edge collapse based repair is used after dark channel prior and guided filter technique. This paper presents the time efficient dehazing of outdoor images with patch size of 25 x 25 and airlight of 3% and this principle is applied to remove Haze in underwater images. The experimental result shows a better result for both outdoor and underwater images.
Game Dynamics and Cost of Learning in Heterogeneous 4G Networks
Venue: IEEE Journal on Selected Areas in Communications
Year: 2012

In this paper, we study game dynamics and learning schemes for heterogeneous 4G networks. We introduce a novel learning scheme called cost to learn that incorporates the cost to switch, the switching delay, and the cost of changing to a new action and, captures the realistic behavior of the users that we have experimented on OPNET simulations. Considering a dynamic and uncertain environment where the users and operators have only a numerical value of their own payoffs as information, we construct various heterogeneous combined fully distributed payoff and strategy reinforcement learning (CODIPAS RL) the users try to learn their own optimal payoff and their optimal strategy simultaneously. We establish the asymptotic pseudo trajectories as solution of differential equations. Using evolutionary game dynamics, we prove the convergence and stability properties in specific classes of dynamic robust games. We provide various numerical examples and OPNET simulations in the context network selection in wireless local area networks (WLAN) and Long Term Evolution (LTE)

Quality characteristics of gochujang meju prepared with different fermentation tools and inoculation time of Aspergillus oryzae
Year: 2010

To standardize a preparation method for traditional gochujang, 4 types of meju were prepared using different fermentation tools and inoculation time of Aspergillus oryzae with Bacillus subtilis. The acidic protease activities of the S 1 and S 2 were higher and significantly different than those of S 3 and S 4 on 8 day fermentation at 30degC. The free amino acid contents of the meju were high, in the order of S 2 (275.9 mg% w/w) S 1 (238.3 mg% S 3 (215.0 mg% S 4 (189.9 mg% The amino type nitrogen contents of the S 1 (355.6+ 12.3 unit/mL) and S 2 (327.0+ 5.8 unit/mL) were higher and significantly different than those of S 3 and S 4 on 4 day fermentation. However, no consistent differences were observed between S 1 and S 2 during the fermentation period. Therefore, we conclude that meju fermentation was largely affected by the inoculation time of A. oryzae rather than the fermentation tool (tray or net)
Magnetic field creation by solar mass neutrino jets
Year: 2018

Parity violation and its effects for neutrinos in astrophysical contexts have been considered earlier in pioneering papers of Hawking and Vilenkin. But because even the largest magnetic moments predicted by physics beyond the Standard Model are some twelve orders of magnitude smaller than the Bohr magneton, their implications for magnetic field generation and neutrino oscillations are generally considered insignificant. Here we show that since in astrophysical scenarios a huge number of neutrinos may be emitted, the smallness of the magnetic moment, when coupled with parity violation, is compensated by the sheer number of neutrinos. The merger of neutron stars would leave behind a short pulse of electromagnetic synchrotron radiation even if the neutrino jet in the merger points away from the neutrino detectors. We show that the magnetic field can be as large as $10^6\\mbox{Gauss} and comment on the possibility of direct detection. Observation of such a pulse would lend strong support for neutrino magnetic moments and resolve the missing neutrino problem in neutron star mergers.
PPG based Finger level Gesture Recognition Leveraging Wearables
Venue: IEEE INFOCOM 2018 IEEE Conference on Computer Communications
Year: 2018

This paper subverts the traditional understanding of Photoplethysmography (PPG) and opens up a new direction of the utility of PPG in commodity wearable devices, especially in the domain of human computer interaction of fine grained gesture recognition. We demonstrate that it is possible to leverage the widely deployed PPG sensors in wrist worn wearable devices to enable finger level gesture recognition, which could facilitate many emerging human computer interactions (e.g. sign language interpretation and virtual reality) While prior solutions in gesture recognition require dedicated devices (e.g. video cameras or IR sensors) or leverage various signals in the environments (e.g. sound, RF or ambient light) this paper introduces the first PPG based gesture recognition system that can differentiate fine grained hand gestures at finger level using commodity wearables. Our innovative system harnesses the unique blood flow changes in a user's wrist area to distinguish the user's finger and hand movements. The insight is that hand gestures involve a series of muscle and tendon movements that compress the arterial geometry with different degrees, resulting in significant motion artifacts to the blood flow with different intensity and time duration. By leveraging the unique characteristics of the motion artifacts to PPG, our system can accurately extract the gesture related signals from the significant background noise (i.e. pulses) and identify different minute finger level gestures. Extensive experiments are conducted with over 3600 gestures collected from 10 adults. Our prototype study using two commodity PPG sensors can differentiate nine finger level gestures from American Sign Language with an average recognition accuracy over 88% suggesting that our PPG based finger level gesture recognition system is promising to be one of the most critical components in sign language translation using wearables.
Lowering the Temperature of Solid Oxide Fuel Cells
Venue: Science
Year: 2011

Fuel cells are uniquely capable of overcoming combustion efficiency limitations (e.g. the Carnot cycle) However, the linking of fuel cells (an energy conversion device) and hydrogen (an energy carrier) has emphasized investment in proton exchange membrane fuel cells as part of a larger hydrogen economy and thus relegated fuel cells to a future technology. In contrast, solid oxide fuel cells are capable of operating on conventional fuels (as well as hydrogen) today. The main issue for solid oxide fuel cells is high operating temperature (about 800degC) and the resulting materials and cost limitations and operating complexities (e.g. thermal cycling) Recent solid oxide fuel cells results have demonstrated extremely high power densities of about 2 watts per square centimeter at 650degC along with flexible fueling, thus enabling higher efficiency within the current fuel infrastructure. Newly developed, high conductivity electrolytes and nanostructured electrode designs provide a path for further performance improvement at much lower temperatures, down to ~350degC, thus providing opportunity to transform the way we convert and store energy.
Cardiac Troponin I and BNP for Predicting Zero Agatston Score in Patients with Diabetes Mellitus
Year: 2021

Coronary artery calcifications (CAC) scoring assessed by the Agatston score has shown an excellent prognostic value in large studies and particularly in diabetic patients, with a very low rate of cardiovascular events in patients with a zero Agatston score. Moreover, recent studies have suggested that high sensitive cardiac troponin I (hs cTnI) and brain natriuretic peptide (BNP) may be useful for detecting subclinical atherosclerosis. However, the link between hs cTnI/BNP and the Agatston score has not been investigated in patients with diabetes.  The aim of this study was to investigate if hs cTnI and BNP can bring additional value to predict zero Agatston score in patients with diabetes mellitus in addition to usual risk factors.  Between 2015 and 2019, CAC score was prospectively performed in consecutive patients with diabetes mellitus. Patients with symptoms, known coronary artery disease or history of atrial fibrillation were excluded. Within 24 h from CT examination, peripheral blood samples were taken to measure hs cTnI and BNP. The relationship between serum hs cTnI/BNP concentrations and zero Agatston score was assessed using univariate and multivariate binomial models. The implication of hs cTnI and BNP in this multivariate model was evaluated using nested models associated with Chi2 test of independence.  A total of 844 patients with diabetes were enrolled (61 7years, 57% men, mean duration of diabetes 18years) In this population, 294(35% had a zero Agatston score, 253(30% an Agatston score from 1 to 100, 161(19% from 101 to 400, and 136(16% higher than 400. In univariate analysis, hs cTnI and BNP concentrations were associated with zero Agatston score (respectively OR, 2.63 [95%CI, 1.51 5.01] P Fig. 1 The most discriminant threshold was 3 ng/l for hs cTnI and Conclusion Cardiac biomarkers hs cTnI and BNP are associated with zero Agatston score, which is correlated with a very low risk of cardiovascular events, in asymptomatic patients with diabetes mellitus.
