1 Low-Dimensional Antiferromagnetic Oxides : An Overview

In the last two decades, the availability of experimental techniques endowed with high sensitivity with respect to the magnetic properties of antiferromagnetic (AFM) materials has motivated a large amount of studies dedicated to the investigation of low-dimensional AFM systems consisting of small particles or films deposited onto either nonmagnetic or ferromagnetic (FM) substrates. Similar to the well-known FM materials, such confined AFM systems are in fact characterized by magnetic properties that, because of interface or size effects, can be considerably different from the ones observed in the bulk [1]. Examples range from the stabilization of exotic AFM ordering to the onset of uniaxial anisotropy in low-dimensional AFM samples. Moreover, systems comprising AFM–FM interfaces represent a world of their own, thanks to their rich phenomenology related to interface exchange coupling. Finite-size effects in both FM and AFM materials reflect deviations from bulk properties associated with the reduction of the sample dimensions. So-called ‘‘intrinsic’’ effects occur in material systems for which one or more sample dimensions, for example, the thickness of a layer or diameter of a particle, is comparable with the intrinsic correlation length scale of the property being considered. Strongly correlated systems such as AFM oxides are characterized by very short correlation lengths, so intrinsic finite-size effects can be observed only in ultrathin films or nanoparticles. In addition, ‘‘surface-related’’ finite-size effects might be caused by the competition between the properties of atoms in the core of a particle or layer and those at the surface, possibly originating from the reduced coordination number. As an example, surface spins often possess higher magnetocrystal anisotropy than the ones in the sample volume because of the reduced symmetry. ‘‘Chemical’’ or ‘‘structural’’ effects may also arise due to phenomena such as surface segregation, relaxation, or reconstruction. Of course, the environment (the material surrounding the particle or the film substrate) can also dramatically alter the properties of interface atoms through hybridization, strain, or chemical interdiffusion, not to mention the crucial role of exchange in determining the magnetism of systems where an AFM material interacts with an FM partner.
Leisure beliefs and the subjective well-being of nations

ABSTRACT The policies of most governments focus on improving material prosperity. Yet, wealth only weakly predicts well-being. It is therefore important to understand whether factors other than money shape the happiness of nations. Here, we construct a data set of 79 countries (N = 220,000) and explore whether differences in the prioritization of time (leisure) vs. money (work) explain cross-country differences in happiness. Consistent with our predictions, countries whose citizens value leisure more than work report higher subjective well-being at the country and individual level. These effects hold in high and low GDP countries. Critically, we find evidence for a novel mechanism: people who value leisure over work are less negatively impacted by financial instability. Moving beyond individual welfare, the value that nations place on leisure vs. work fundamentally shapes happiness.
Prevalence of major depressive disorder among Spanish adolescents

The main objective of this study was to examine the prevalence of major depressive disorder (MDD) among adolescents in a city of 200,000 inhabitants using a psychiatric diagnostic tool. We also looked into how possible internal/external factors may influence prevalence and examined the comorbidity between MDD and other psychiatric disorders. The study population included 1,238 adolescents in their final year of secondary education in Sabadell (Barcelona, Spain). A prospective observational study in two phases: (a) Initial population-based screening using the Beck Depression Inventory (BDI), and (b) Diagnosis using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) with participants who, according to screening, exhibited significant depressive symptoms. The Child Behavior Check-list (CBCL) and the State-Trait Anxiety Inventory for Children (STAIC) were also used in the second phase of the study, which, together with K-SADS, enabled us to examine the comorbidity of MDD with other disorders. According to the initial screening, 7.92% of participants exhibited significant depressive symptoms. The results of the diagnostic interviews showed a prevalence of 1.29% adolescents with MDD. Prevalence was higher in girls (1.92%) than in boys 0.34%) (p=0.002) and at age 16 or over in both genders (p<0.001). 50% of participants with MDD presented comorbidity with other psychiatric pathologies. The low prevalence of MDD observed does not justify generalised screening in adolescents attending school, except in cases of individuals with significant depressive symptoms. Key words: Depression, major depressive, disorder, adolescence, prevalence, screening, comorbidity.
Effect of Ultrasonic Lipocavitation on Normal Lipid Profile in Healthy Subjects

This study was conducted to investigate the effect of low frequency ultrasonic lipocavitation on normal lipid profile in healthy subjects with localized fat deposits in abdomen. Design: one group repeated measure. Subject, material and method: forty eight volunteer healthy women participated in the study, their age was (2545) years old and their BMI was (2535) Kg/m. All of them adhered to balanced healthy diet to maintain body weight and received 12 sessions of ultrasonic lipocavitation on abdominal area along 6 weeks with session frequency of 2 sessions weekly and session duration of 25 min with ultrasonic Frequency of 32 -36 KHz, Output Power of 10-70 Watt/cm2. Lipid profile, BMI, WC, AC, WHR, BFM and TF were measured before treatment, after 4 weeks of treatment and repeated again at the end of treatment after 6 weeks. Results showed a significant decrease in values of TC, TGs, LDL, WC, AC, WHR, BFM and TF mass. Also significant increase in HDL favoring "post 4 weeks of treatment" and " post 6 weeks of treatment " in compare to pretreatment and favoring post 6 weeks in compare to post 4 weeks of treatment. Conclusion: Low frequency ultrasonic lipocavitation was effective in improving lipid profile and reducing abdominal localized fat deposits.
ePubWU Institutional Repository

For companies that develop and operate IT applications that process the personal data of customers and employees, a major problem is protecting this data and preventing privacy breaches. Failure to adequately address this problem can result in considerable damage to the company’s reputation and finances, as well as negative affects for customers or employees (data subjects). We address this problem by proposing a methodology that systematically considers privacy issues by using a step-bystep privacy impact assessment (so called ‘PIA’). Existing PIA approaches lack easy applicability because they are either insufficiently structured or imprecise and lengthy. We argue that companies that employ the PIA proposed in this article can achieve ‘privacy-by-design’, which is widely heralded by data protection authorities. In fact, the German Federal Office for Information Security (BSI) ratified the approach we present in this article for the technical field of RFID and published it as a guideline in November 2011. The contribution of the artefacts we created is twofold: First, we provide a formal problem representation structure for the analysis of privacy requirements. Second, we reduce the complexity of the privacy regulation landscape for practitioners who need to make privacy management decisions for their IT applications.
Factors influencing knowledge sharing among layers: The case of Vietnam

Article history: Received: August 8 2019 Received in revised format: September 22 2019 Accepted: October4, 2019 Available online: October 4, 2019 Knowledge plays an important role for the development of any economy, any business especially within the law profession which requires profound knowledge. Knowledge sharing behaviors may improve the performance of the work. The proposed study of this paper is conducted among 398 lawyers in Vietnam to assess the factors affecting the knowledge sharing behavior of lawyers. After analyzing data based on Smart PLS software, the results show that the knowledge sharing behavior of lawyers in Vietnam contributes to their jobs except for the development process according to the planned behavioral theory. At the same time, the paper examines the mediating role of behavioral intent for the relationship between attitude and knowledge-sharing behavior which is statistically significant. However, the level of information use does not have any statistically significant role for the relationship between intentional behavior and knowledge sharing behavior of lawyers in Vietnam. © 2020 by the authors; licensee Growing Science, Canada

Conclusion La CNM et la toxoplasmose cerebrale sont les IO a evoquer en cas d’atteinte du systeme nerveux central chez le PVVIH.
Sector and Importer Determinants of Prices for Traded Intermediates

While the literature on traded goods prices emphasizes final goods prices and related consumer theory to explain variation in goods prices with importer characteristics, trade in intermediates actually constitutes about two-thirds of total trade. We propose a mechanism for explaining variations in the prices of intermediates as a function of importer characteristics, wherein production is vulnerable to failure and the probability of failure declines in the quality of intermediates. Higher wages mean a greater opportunity cost of failure, leading to a stronger demand for high-quality intermediates where firms face higher wages. We find empirical support for this mechanism in the case of intermediate goods using IV regressions. In addition, our findings indicate that while the cost of labor explains about one-fifth of variation in imported intermediate prices, it is a non-significant determinant of imported final good prices.
Optimization Strategy for Generating Gene-edited Tibet Minipigs by Synchronized Oestrus and Cytoplasmic Microinjection

The Tibet minipig is a rare highland pig breed worldwide and has many applications in biomedical and agricultural research. However, Tibet minipigs are not like domesticated pigs in that their ovulation number is low, which is unfavourable for the collection of zygotes. Partly for this reason, few studies have reported the successful generation of genetically modified Tibet minipigs by zygote injection. To address this issue, we described an efficient way to generate gene-edited Tibet minipigs, the major elements of which include the utilization of synchronized oestrus instead of superovulation to obtain zygotes, optimization of the preparation strategy, and co-injection of clustered regularly interspaced short palindromic repeat sequences associated protein 9 (Cas9) mRNA and single-guide RNAs (sgRNAs) into the cytoplasm of zygotes. We successfully obtained allelic TYR gene knockout (TYR-/-) Tibet minipigs with a typical albino phenotype (i.e., red-coloured eyes with light pink-tinted irises and no pigmentation in the skin and hair) as well as TYR-/-IL2RG-/- and TYR-/-RAG1-/- Tibet minipigs with typical phenotypes of albinism and immunodeficiency, which was characterized by thymic atrophy and abnormal immunocyte proportions. The overall gene editing efficiency was 75% for the TYR single gene knockout, while for TYR-IL2RG and TYR-RAG1 dual gene editing, the values were 25% and 75%, respectively. No detectable off-target mutations were observed. By intercrossing F0 generation minipigs, targeted genetic mutations can also be transmitted to gene-edited minipigs' offspring through germ line transmission. This study is a valuable exploration for the efficient generation of gene-edited Tibet minipigs with medical research value in the future.
Sexual Violence and Associated Factors Among Female Students of Preparatory Schools in Modjo and Bishoftu Towns of East Showa Zone, Oromia State, Ethiopia

Worldwide, the range and magnitude of sexual violence have tremendous negative impact for both the individual and society. This study was conducted to assess the prevalence of sexual violence and associated factors among female students of preparatory schools in Modjo and Bishoftu towns from September 1 to December 30, 2018. Institutional based cross-sectional study design was conducted. A sample of 323 female students was randomly taken from four preparatory schools. The collected data was entered into Epi Info 7 and exported to SPSS version 20 for analysis. Four FGD’s were conducted targeting community representatives and the required sample size was determined based on the saturation of information. The study showed a prevalence of 74% of sexual violence in the study area. Iin the final model, age group of 17 - 18 (AOR: 6.39; 95% of CI: 3.64, 63.12), teacher perpetrator (AOR, 0.37; 95%CI: 0.01, 0.13) and knowledge of ever encountered a person with sexual violence (AOR, 1.21; 95%CI: 1.13, 4.59) was found significant (P<0.05). A significant proportion (74%) of respondent’s experienced sexual violence. Unwelcome touching and ever had sexual intercourse without their consents were the most common types of sexual violence in the study area. Lower age, perpetrator category and knowledge towards sexual violence were associated with sexual violence. There is a need to have systematic and strategic intervention using school based programs to address the full context of female students and others young girl lives, including society, behavioral and environmental factors leading to the problem of sexual violence.
The evolutionary terrestrialization of planarian flatworms (Platyhelminthes, Tricladida, Geoplanidae): a review and research programme

The terrestrialization of animal life from aquatic ancestors is a key transition during the history of life. Planarian flatworms form an ideal group of model organisms to study this colonization of the land because they have freshwater, marine, and terrestrial representatives. The widespread occurrence of terrestrial flatworms is a testament to their remarkable success occupying a new niche on land. This lineage of terrestrial worms provides a unique glimpse of an evolutionary pathway by which a group of early divergent aquatic, invertebrate metazoans has moved onto land. Land flatworms are among the first groups of animals to have evolved terrestrial adaptations and to have extensively radiated. Study of this terrestrialization process and the anatomical key innovations facilitating their colonization of the land will contribute greatly to our understanding of this important step in Metazoan history. The context and scientific background are reviewed regarding the evolutionary terrestrialization of land flatworms. Furthermore, a framework of a research programme is sketched, which has as its main objective to test hypotheses on the evolution of land planarians, specifically whether particular anatomical and physiological key innovations have contributed to their evolutionary successful terrestrial colonization and radiation. In this context special attention is paid to the respiration in aquatic and terrestrial planarians. The research programme depends on a comprehensive phylogenetic analysis of all major taxa of the land flatworms on the basis of both molecular and anatomical data. The data sets should be analyzed phylogenetically with a suite of phylogenetic inference methods. Building on such robust reconstructions, it will be possible to study associations between key innovations and the evolutionary terrestrialization process.
Ultrasensitive Wearable Strain Sensors of 3D Printing Tough and Conductive Hydrogels

In this study, tough and conductive hydrogels were printed by 3D printing method. The combination of thermo-responsive agar and ionic-responsive alginate can highly improve the shape fidelity. With addition of agar, ink viscosity was enhanced, further improving its rheological characteristics for a precise printing. After printing, the printed construct was cured via free radical polymerization, and alginate was crosslinked by calcium ions. Most importantly, with calcium crosslinking of alginate, mechanical properties of 3D printed hydrogels are greatly improved. Furthermore, these 3D printed hydrogels can serve as ionic conductors, because hydrogels contain large amounts of water that dissolve excess calcium ions. A wearable resistive strain sensor that can quickly and precisely detect human motions like finger bending was fabricated by a 3D printed hydrogel film. These results demonstrate that the conductive, transparent, and stretchable hydrogels are promising candidates as soft wearable electronics for healthcare, robotics and entertainment.
LoCo: Localizing Congestion

Datacenter congestion control remains to be a hard problem. The challenge is that while congestion control is usually implemented at the end-hosts, congestion itself can happen at network switches. Thus, the ability of end-hosts to react to congestion is fundamentally limited by the timeliness and precision of congestion signals from the network. Unfortunately, despite decades of research, the community is still in quest of such timely and precise congestion signals. LoCo takes a new approach to resolving the congestion control problem: it localizes the congestion to egress queues of the end-hosts, precisely where congestion control is implemented, while bounding both the worst-case queuing at each switch and the network utilization. LoCo achieves this by exploiting the structure in datacenter network topologies to perform network-wide admission control for each and every packet in the network. LoCo is a clean-slate design that requires changes in network switches as well as end-hosts NICs. We evaluate LoCo using both an end-to-end hardware implementation and large-scale simulations; our results show that LoCo not only achieves the above mentioned theoretical guarantees, but also achieves better performance than several state-of-the-art congestion control protocols over standard datacenter workloads.

Coping Strategies in Male Patients under Treatment for Substance Use Disorders and/or Severe Mental Illness: Influence in Clinical Course at One-Year Follow-Up

Coping strategies have an impact on substance use disorders (SUD), relapses, and clinical variables, but knowledge on this area is scarce. We explored the coping strategies used during treatment in patients with dual diagnosis (DD), SUD, and severe mental illness (SMI), and the relation with clinical course and relapses at one-year follow-up. A sample of 223 patients was divided into three groups depending on diagnosis: DD (N = 80; SUD with comorbid schizophrenia or major depressive disorder), SUD only (N = 80), and SMI only (N = 63; schizophrenia or major depressive disorder). MANCOVA analyses reflected differences in self-criticism and problem avoidance, with a higher use of these in the DD and SUD groups. The coping strategies used differed depending on the presence/absence of a SUD, but not depending on psychiatric diagnosis. At one-year follow-up, social support was the only strategy that predicted the presence of relapses in DD patients with schizophrenia (positively), and in SMI patients with major depressive disorder (negatively). Thus, social support was associated with relapses, but the relationship was different depending on psychiatric diagnosis. Further studies should analyze the implications of social support as a coping strategy in different mental disorders, as well as its usefulness in individualized interventions.
