Rock magnetic investigation of possible sources of the Bangui magnetic anomaly

The Bangui magnetic anomaly (BMA) is the largest lithospheric magnetic field anomaly on Earth at low latitudes. Previous studies investigated its geological source using constraints from satellite and ground magnetic field measurements, as well as from surface magnetic susceptibility measurements on rocks from the Panafrican Mobile Belt Zone (PMBZ). Here we combine magnetic field data modelling and rock magnetic property measurements (susceptibility and natural remanent magnetization, NRM) on many samples from this PMBZ and the surrounding formations. It reveals that NRM is a significant component of the total magnetization (Mt) of the BMA source, which reaches 4.3 A/m with maximum thicknesses of 38 and 54 km beneath the western and eastern parts of the BMA. Only the isolated and relatively thin banded iron formations and some migmatites show such Mt values. Thus we suggest that the thick BMA source may be composed either by overlapped slices of such metamorphic rocks, or by an iron-rich mafic source, or by a combination of these two geological structures.
Joint dynamics during infant learning

Infants spend most of their waking time interacting with their caregivers, and the mechanisms through which these dynamic social exchanges shape the development of sub-personal processes such as attention and learning remain mysterious. Most of our understanding of how the brain subserves early attention and learning has come from studies that viewed infants as relatively passive recipient of information, and studied individual brains in isolation. Correspondingly, we know very little about the neural substrates of how information is shared between caregivers and infants during learning interactions. The aim of this project is to shed unprecedented light on how dynamic social interactions affect attention and learning during infancy. I will build both on my own recent research, that has shown that internal metacognitive monitoring and epistemic requests from the infant shape social interactions and learning more than had previously been thought, and combine this approach - that views the infant as an active component of early social interactions - with innovative research by my supervisor that provides the possibility to record brain activity from infants and their caregivers simultaneously while they are interacting, and to analyze them with specific tools that allow a fine description of the dynamics of these interaction. Combining these two approaches will provide invaluable insight into the mechanisms involved during early learning in social contexts. Our findings will have substantial implications for theories of development, as well as diagnostic and educational practices. More specifically, increasing our understanding of the complex dynamics between infants and their social partners is essential for: i) enriching developmental theory; ii) developing new techniques to optimize learning and iii) understanding the mechanisms that give rise to developmental delays.
Oxytocin and psychotherapy: A pilot study of its physiological, behavioral and subjective effects in males with depression

Individual psychotherapy is an important treatment for a number of psychiatric conditions and involves a unique form of human attachment. This raises the question of whether oxytocin (OT), the paradigmatic "attachment hormone", may have benefits in this context. In this randomized, double-blind, crossover trial, we gave male psychiatric outpatients with major depressive disorder 40 IU intranasal OT or placebo before a videotaped session with a therapist and measured a number of subjective, physiological, and behavioral parameters. We report three main findings. Surprisingly - in contrast to prior reports of OT's anxiolytic properties - we found OT caused an increase in anxiety over the course of the therapy session. Secondly, though it had no main effect on cortisol, eye contact, or overall behavior, we did find that OT caused a decrease in nonverbal behaviors that cut off social contact, after controlling for level of depressive symptoms. Lastly, we replicated prior findings that OT improves social cognition (performance on the reading the mind in the eyes test (RMET)), albeit in a depressed patient group. These results inform future studies of oxytocin and psychotherapy and suggest that in certain clinical populations and contexts, OT has heterogeneous subjective effects which may include acute anxiogenesis. Moreover, the similarity of some of these acute effects to those of single-dose serotonergic antidepressants raises interesting questions about the potential antidepressant benefits of chronic OT administration.
Gaia 1 and 2. A pair of new Galactic star clusters

We present the results of the very first search for faint Milky Way satellites in the Gaia data. Using stellar positions only, we are able to re-discover objects detected in much deeper data as recently as the last couple of years. While we do not identify new prominent ultra-faint dwarf galaxies, we report the discovery of two new star clusters, Gaia 1 and Gaia 2. Gaia 1 is particularly curious, as it is a massive (2.2$\times$10$^4$ M$_\odot$), large ($\sim$9 pc) and nearby (4.6 kpc) cluster, situated 10' away from the brightest star on the sky, Sirius! Even though this satellite is detected at significance in excess of 10, it was missed by previous sky surveys. We conclude that Gaia possesses powerful and unique capabilities for satellite detection thanks to its unrivalled angular resolution and highly efficient object classification.

Optical nonlinearities in non-peripherally substituted pyridyloxy phthalocyanines: a combined effect of symmetry, ring-strain and demetallation

The optical nonlinearities of six non-peripherally-substituted pyridyloxy phthalocyanines have been studied at 532 nm using a nanosecond Z-scan technique in a dimethyl sulphoxide solution. Ring-strain effects and the absence of a metal center were found to greatly reduce the inherent high nonlinearities expected of some of these phthalocyanine complexes. Of the six molecules investigated, 1(4),8(11),15(18),22(25)-tetrakis-(2-pyridyloxy)phthalocyaninato lead(II) 3, 1(4),8(11),15(18),22(25)-tetrakis-(2-pyridyloxy)phthalocyanine 5, and 1(4),8(11),15(18),22(25)-tetrakis-(4-pyridyloxy)phthalocyanine 6 were found to exhibit negligible nonlinear optical behavior, due to either the absence of asymmetry or central metal and/or the presence of a ring-strain effect. A two-photon absorption process was found to be the major contributor to the observed reverse saturable absorption (RSA) in 1(4),8(11),15(18),22(25)-tetrakis-(4-pyridyloxy)phthalocyaninato lead(II) 4, 1(4)-mono-(2-pyridyloxy)phthalocyaninato lead(II) 7, and 1(4)-mono-(4-pyridyloxy)phthalocyaninato lead(II) 8, with large two-photon absorption cross-section, high hyperpolarizability and high third-order susceptibility values in the range of 4.53 × 10(-43)-5.33 × 10(-42) cm(4) s per photon, 1.61 × 10(-28)-1.89 × 10(-27) esu and 9.73 × 10(-12)-7.05 × 10(-11) esu respectively.
Vagal stimulation to suppress alternans: Are we saving lives or simply masking surrogate markers?

Multiple studies have demonstrated that the functional modulation of the heart exerted by the autonomic nervous system (ANS) can prove maladaptive in the context of heart failure (HF), and it is evident that increased sympathetic and reduced parasympathetic tone play an important pathophysiological role in the progression of HF irrespective of its etiology. In light of its implications in the pathogenesis of HF, there has been growing interest in the potential of ANSmodulation as HF therapy. Theoretically, it is conceivable that enhancing parasympathetic tone to counteract the adverse effects of excessive adrenergic activity could ameliorate or even reverse the course of this progressive disease. Parasympathetic modulation of the heart is carried by the right and left vagus nerves, originating in the medulla and connecting with postganglionic neurons in ganglionated plexi located in the epicardium. The anatomical accessibility of the cervical vagus nerves and their response to electrical impulses provide a unique opportunity to interfere with ANS responses to disease. In 1967 Braunwald et al demonstrated that vagal nerve stimulation (VNS) could reproducibly attenuate angina symptoms and improve exercise capacity in 2 patients after myocardial infarction. Schwartz et al studied the effect of VNS in a series of 8 patients with advanced HF. They demonstrated a significant improvement in left ventricular end-systolic volume and functional class. A nonrandomized study of 32 patients with HF with reduced left ventricular ejection fraction (LVEF) reported that VNS favorably influenced quality of life, exercise capacity, and left ventricular remodeling. However, larger randomized studies have failed to systematically replicate these effects. A sham-controlled trial (NECTAR-HF) showed no benefit of VNS in LVEF or left ventricular remodeling. The ANTHEM-HF trial randomly assigned 31 and 29 patients to left and right cervical VNS, respectively. In contrast to NECTAR-HF, modest but
Taming non convexity?

In many important areas and applications of science one has to solve non convex optimization problems and  ideally and ultimately one would like to find the global optimum. However in most cases one is faced with NP-hard problems and therefore in practice one has been often satisfied with only a local optimum obtained  with some ad-hoc (local) optimization algorithm. 

TAMING intends to provide a systematic methodology for solving hard non convex polynomial optimization problems in all areas of science. Indeed the last decade has witnessed the emergence of Polynomial Optimization as a new field in which powerful positivity certificates from real algebraic geometry have permitted to develop an original and systematic approach to solve (at global optimality) optimization problems with polynomial (and even semi-algebraic) data.  The backbone of this powerful methodology is the « moment-SOS » approach also known as « Lasserre hierarchy » which has attracted a lot of attention in many areas (e.g., optimization, applied mathematics, quantum computing, engineering, theoretical computer science) with important potential applications. It is now a basic tool for analyzing hardness of approximation in combinatorial optimization and the best candidate algorithm to prove/disprove the famous Unique Games Conjecture. Recently it has also become a promising new method for solving the important Optimal Power Flow Problem in the strategic domain of Energy Networks (as the only method that could solve to optimality certain types of such problems). 

However in its present form this promising methodology inherits a high computational cost and a (too) severe problem size limitation which precludes from its application many important real life problems of significant size. Proving that indeed this methodology can fulfill its promises and solve important practical problems in various areas poses major theoretical & practical challenges.
The number of missing teeth in people of the Edo period in Japan in the 17th to 19th centuries

The aims of this study were to examine the number of missing teeth in the people of the Edo period (or number of remaining teeth) and to contribute to the 8020 movement proposed in Japan to help people retain 20 or more of their own teeth until the age of 80.The study of dentition in ancient skeletal remains of our ancestors from multiple perspectives can yield information that can contribute to the study of physical anthropology and the leading edge of modern dental research.The materials were 82 excavated individuals (52 males and 30 females) from 1603 to 1868 whose maxillas and mandibles were both examinable. The age and sex were estimated by anthropological methods, and the individuals were divided into five groups. The status of missing teeth was compared between groups, and a chi-square test was used to test significant differences between groups. The rates of tooth loss were examined in the maxillas and mandibles.In the people of the Edo period, many teeth remained in good condition until early to late middle age. There were more remaining teeth in these individuals than in modern-day individuals. However, the Edo people clearly showed increased tooth loss with age. There were no differences in tooth loss by sex. The tooth type with a high rate of tooth loss was posterior teeth, but incisor loss also occurred with ageing. Mandibular canines were most likely to be remaining.The Edo people had more remaining teeth than modern-day society. This finding was unexpected. The notion that "people of long past ages lost more teeth more quickly" does not seem to apply to people in the Edo period in Japan.

Minimizing bottleneck nodes of a substrate in virtual network embedding

Network virtualization has been proposed as a way to increase the flexibility of the Internet. This could enable the provisioning of many desired services in the current architecture and allow effective sharing and use of resources. Providing virtual networks (VNs) means that virtual nodes and links need to be embedded in the underlying shared infrastructure. This embedding process, where VNs with resource demands are mapped onto a substrate with finite resources is a challenging and NP-hard problem. In this paper the focus is on mapping the VNs in such a way that node resources in the substrate are not completely exhausted. To achieve this objective, an approach referred to as bottleneck node reduced mapping is presented. This method is evaluated and compared with an approach, where resource exhaustion is not considered.
CUTTING HEAD FOR YARN CUTTING DEVICE.

Dans une tête de coupe pour un coupe-fil entraîné par moteur électrique, le réglage automatique de la longueur du fil s'effectue par segments grâce à un mouvement rotatif entre une bobine de fil (36) et une douille (24) déplaçable axialement et logeant celle-ci. La douille (24) est dotée à l'extérieur d'ergots de verrouillage alors que la bobine de fil comporte à l'intérieur des ergots coopérant avec ces derniers. La douille (24) peut être introduite par glissement à la main en réponse à une force de ressort afin de supprimer le verrouillage par segments. Un déplacement centrifuge est prévu pour un réglage automatique du fil. A cet effet, au moins deux fentes sphériques radiales (40) sont prévues entre la partie de boîtier (14) et un prolongement radial (48) de la douille (24); dans les fentes sphériques sont conduites des boules (44) qui peuvent être poussées vers l'extérieur par la force centrifuge. La modification de la hauteur de la fente sphérique sur un plan incliné (42) provoque, lors d'une sortie radiale des boules (44), un écartement des deux parties (48, 14), ce qui entraîne un déverrouillage par segments. Les divers segments d'angle de rotation sont limités par des ergots inférieurs, respectivement supérieurs, avec lesquels coopère un contre-ergot commandé par le mouvement de déplacement et coopérant alternativement avec l'un ou l'autre ergot, le déplacement angulaire par segments provenant du démarrage et de l'arrêt répétés du moteur.
Robust iris identification system using local descriptors

In all biometrics, iris contains rich texture for person identification and has its distinctive advantages because of its large inter-class variability and low intra-class variability. This research provides a fast and robust iris identification system. In this proposed system for iris recognition Daisy descriptors have been used as features which has been modified considering the context of iris recognition. After feature extraction, a Feature matching algorithm has also been proposed which provides much better results. The performance of proposed iris recognition system has been evaluated through exhaustive experimentation on standard CASIA Iris Lamp Database and the results exhibit the improvement in recognition accuracy.
Partial Deregulation and Competition: Effects on Risky Mortgage Origination

We exploit the preemption of national banks from state laws against predatory lending by the Office of the Comptroller of the Currency (OCC) as a quasi-experiment to study the effect of deregulation and its interaction with competition on the supply of complex mortgages. Following the preemption ruling, national banks significantly increased their origination of loans with prepayment penalties relative to national banks in states without anti-predatory-lending laws. We highlight a competition channel: in counties where OCC-regulated lenders had larger market shares, non-OCC-regulated lenders responded by increasing their supply of contracts with riskier features, such as deferred amortization, which were not restricted by the state anti-predatory-lending law. Non-OCC lenders were able to lure borrowers into these higher-margin contracts by increasing their appeal with teaser rates. This paper was accepted by Tyler Shumway, finance.
Phacoemulsification in a Rare Case of Alport’s Syndrome

To report a rare case of Alport Syndrome (AS) highlighting the precautions and surgical complications during phacoemulsification.A 35 year old female presented with bilateral painless progressive diminution of vision since 6 months and had bilateral deafness since 12 years. Best corrected visual acuity (BCVA) in both the eyes was 4/60. Bilateral anterior lenticonus, posterior polar cataract with posterior lenticonus, macular and peripheral retinal flecks, which are rarely reported in females, were present. Right eye phacoemulsification and IOL implantation was done.During surgery capsulorrhexis underwent multiple dehiscence in a "flower petal pattern" due to fragile capsule. It was completed with microforceps under high viscocity viscoelastic. IOL was placed in sulcus due to extension of capsulorrhexis. BCVA was 6/12 at 1 month.This rare case highlights the importance of an eye ailment in revealing an important systemic disease. It also highlights proper management of complications that can give good result even in difficult cases.
