Turning Your Weakness Into a Strength: Watermarking Deep Neural Networks by Backdooring

Deep Neural Networks have recently gained lots of success after enabling several breakthroughs in notoriously challenging problems. Training these networks is computationally expensive and requires vast amounts of training data. Selling such pre-trained models can, therefore, be a lucrative business model. Unfortunately, once the models are sold they can be easily copied and redistributed. To avoid this, a tracking mechanism to identify models as the intellectual property of a particular vendor is necessary. In this work, we present an approach for watermarking Deep Neural Networks in a black-box way. Our scheme works for general classification tasks and can easily be combined with current learning algorithms. We show experimentally that such a watermark has no noticeable impact on the primary task that the model is designed for. Moreover, we evaluate the robustness of our proposal against a multitude of practical attacks.
Crystallization and High Mechanical Strength of Al-Based Amorphous Alloys

Crystallization behavior upon aging and its influence on mechanical properties were examined for Al 88 Ni 10 Y 2 and Al 88 Ni 10 Ce 2 amorphous alloys. The crystallized structure of the amorphous alloys consists of coexistent amorphous and fcc-Al phase with a particle size of 5 to 12 nm. The thermal stability increases significantly with an increase of the precipitation amount (V f ) of the nanoscale Al particles. The hardness (H v ) and tensile fracture strength (σ f ) of these amorphous alloys containing the nanoscale Al particles are about 2-0 and 1-3 times higher than those for the amorphous single phase alloys with the same compositions, respectively
Gallium enhances reconstructive properties of a calcium phosphate bone biomaterial

Calcium phosphate (CaP)‐based biomaterials are commonly used in bone reconstructive surgery to replace the damaged tissue, and can also serve as vectors for local drug delivery. Due to its inhibitory action on osteoclasts, the semi‐metallic element gallium (Ga) is used for the systemic treatment of disorders associated with accelerated bone resorption. As it was demonstrated that Ga could be incorporated in the structure of CaP biomaterials, we investigated the biological properties of Ga‐loaded CaP biomaterials. Culturing bone cells on Ga–CaP, we observed a decrease in osteoclast number and a downregulation of late osteoclastic markers expression, while Ga–CaP upregulated the expression of osteoblastic marker genes involved in the maturation of bone matrix. We next investigated in vivo bone reconstructive properties of different Ga‐loaded biomaterials using a murine bone defect healing model. All implanted biomaterials showed a good osseointegration into the surrounding host tissue, accompanied by a successful bone ingrowth and bone marrow reconstruction, as evidenced by histological analysis. Moreover, quantitative micro‐computed tomography analysis of implants revealed that Ga enhanced total defect filling. Lastly, we took advantage for the first time of a particular mode of non‐linear microscopy (second harmonic generation) to quantify in vivo bone tissue reconstruction within a CaP bone substitute. By doing so, we showed that Ga exerted a positive impact on mature organized collagen synthesis. As a whole, our data support the hypothesis that Ga represents an attractive additive to CaP biomaterials for bone reconstructive surgery. Copyright © 2017 John Wiley & Sons, Ltd.
Modelling biogeochemical fluxes across a Mediterranean fish cage farm

An integrated approach is described for modelling interactions between off-shore fish cages and biogeochemical fluxes of carbon (C), nitrogen (N) and phosphorus (P). Two individ- ual-based population dynamic models for European seabass Dicentrarchus labrax and gilthead seabream Sparus aurata were coupled with a Lagrangian deposition and a benthic degradation model. The individual models explicitly take into account the effects of water temperature and feed availability on fish growth. The integrated model was tested at a Mediterranean fish farm where a comprehensive set of in situ environmental and husbandry data was available. Tests were performed to compare the predicted and observed total organic carbon (TOC) concentrations in surface sediment under and near fish cages. At a local scale, the model output simulated the spa- tial distribution of 4 biogeochemical indicators, namely: TOC concentrations, C fluxes towards the seabed and C:N and C:P ratios. These allowed the most impacted areas and more extended areas of intermediate organic enrichment to be identified. The model was also used for estimating the mass balance of C, N and P, in order to determine the potential cumulative effects of multiple fish farms in the same area. The C, N and P fluxes among feed, fish and environment were calculated for each fish species over 24 mo of farm activity. The results showed that the amount of dissolved N directly released into the water column in inorganic form (ammonia/urea) was comparable to that deposited on the seafloor in particulate form as uneaten feed and faeces. A larger fraction of P (about 65%) was released as faeces. Results from the integrated model yielded useful informa- tion for assessing the sustainability of an area for aquaculture activities that could be used to pro- vide a scientific rationale for fish farm development in new areas.
Effect of ACL reconstruction graft size on simulated Lachman testing: a finite element analysis.

INTRODUCTION ACL reconstructions are frequently performed following ACL injury. The most common treatment is single bundle reconstruction. While ACL reconstructions have been studied clinically and experimentally, quantitative information regarding the local biomechanics the knee following ACL reconstruction is generally lacking. Specifically, the role of graft size on joint stability and soft tissue injury propensity is currently unknown. METHODS Therefore, a non-linear contact finite element model was developed to systematically evaluate the relationship between ACL graft size and knee joint biomechanics following ACL reconstruction. A simulated Lachman maneuver was utilized to assess knee joint laxity, meniscal stress, in situ graft loading, and peak articular cartilage contact pressure for ACL graft sizes between 5 and 9 mm, as well as an ACL-deficient knee. The model was validated by corroboration with previously published experimental (cadaveric) data on ACL reconstruction. RESULTS The 5 mm graft resulted in 30% greater relative AP translation compared to the 9 mm graft; the ACL deficient knee resulted in 2.56-times greater AP translation than the average graft reconstruction. Contact pressure and peak meniscal stresses decreased monotonically for increased values of ACL graft diameter. For all graft diameters, soft tissue stress and articular contact pressure was reduced versus the ACL-deficient knee. CONCLUSIONS ACL reconstruction dramatically affects the local biomechanics of the knee. Stresses occurring in the soft tissues, as well as contact pressure at the articular surfaces, were found to be highly sensitive to ACL graft size. Larger grafts were associated with lower meniscal stress, decreased joint laxity, and less articular cartilage contact stress. Therefore, the current data suggests that increased graft size confers a biomechanical advantage in the ACL reconstructed knee.
Effect of Endometrial Cavity Fluid On Pregnancy Rate of Fresh Versus Frozen In Vitro Fertilization Cycle

Objective: This study aims to study the difference in etiology and outcome in terms of implantation rate and abortion rate in fresh (self-stimulated) versus frozen (oocyte donation cycle) in vitro fertilization (IVF) and in transient versus persistent fluid. Material and Methods: This retrospective study was conducted in the Department of Reproductive Medicine of tertiary care center from January 2012 to November 2015. Data were collected retrospectively from the departmental files. Twenty-four patients from fresh IVF-stimulated cycles and 24 from frozen oocyte donation cycle with their endometrium prepared by hormone replacement treatment were included in the study. All patients selected in the study had grade-A embryo transfer of day 3–4 with maximum three embryo transferred. Pregnancy was defined by rising serum beta-human chorionic gonadotrophin levels performed after 14 days of embryo transfer and further confirmed by ultrasonographic visualization of gestational sac at 6 weeks. All biochemical pregnancies were included in implantation failure. All pregnant patients were followed till the termination of pregnancy and further noted as live birth or abortion. Results: Clinical pregnancy rate was seen more in self-stimulated cycle (62.5%) with live birth rate of 50% than hormone replacement treatment cycle, in which clinical pregnancy rate was 45.83% with live birth rate of 33.33%. Clinical pregnancy rate was highest in group with very less fluid in cavity (1–2 mm) 63% and with live birth of 52.63%. Clinical pregnancy was seen only in two patients of group B with anterior and posterior (AP) diameter of fluid in cavity of 2–3 mm with live birth of only one, whereas in group C, with AP diameter of 3–5 mm, none of the patient conceived. This difference was statistically significant. Clinical pregnancy rate was 65.62% in transient fluid accumulation with live birth rate of 53.25%, which was significantly higher than persistent fluid accumulation (P value − 0.0337 for pregnancy rate and 0.0312 for live birth rate). Conclusion: Fluid accumulation seen in fresh cycles are generally associated with better outcome because it may be associated with good prognostic factors – small AP diameter of fluid, with transient fluid accumulation and more with poly cystic ovarian syndrome as an etiological factor; however, in frozen cycle, it can be associated with poor outcome.
Internalization of the Sociocultural Ideal: Weight-Related Attitudes and Dieting Behaviors among Young Adolescent Girls

Questionnaires returned from 234 fifth and sixth graders from 24 Girl Scout Troops in the Midwest showed that 29.3% of all girls and 68.7% of those who were dieting thought they were overweight. Most of those who were trying to lose weight were using healthy methods, but a few were using dangerous methods. Very few were unhappy with their weight, shape, and various body parts. Most appeared to be aware of the influence of media on body image and were accepting of a wide range of body shapes and sizes among themselves and their friends.
A numerical model for externally prestressed beams

A method to numerically evaluate the behaviour of single span beams, prestressed with external tendons and symmetrically loaded is presented. This algorithm, based on the Finite Difference Method, includes second order effects and large displacements in an attempt to more fully understand the behaviour of the beam up to collapse. The numerical technique discussed is particularly appropriate for the analysis of R.C. and P.C. beams rehabilitated or strengthened by means of external prestressing but it is reliable for the analysis of new beams as well.
The Ecology of Urban Violence: Its Relationship to Health Promotion Behaviors in Low-Income Black and Latino Communities

Purpose. The purpose of this review is to identify and examine relationships between exposure to violence and health promotion behaviors in low-income black and Latino groups. Design. Based on computer surveys of the psychologic, public health, medical, and sociologic literature, approximately 90 previous studies of the impact of exposure to violence on psychologic functioning, perceptions of health and well-being, and health decisions and behavior were identified. This article reviews those studies that examine the relationships between experiences of violence and subsequent feelings of alienation, powerlessness, and hopelessness, and perceptions of health and well-being and studies that examine relationships between alienation, hopelessness, and powerlessness and health promotion behaviors. Studies of health promotion behavior that did not examine or address the impact of exposure to violence are not reviewed in this article. Results. Violence affects low-income communities directly by contributing to rates of mortality, and indirectly by affecting health promotion behaviors. Exposure to violence can result in feelings of powerlessness, hopelessness, and alienation that significantly limit motivation, the extent of involvement, and persistence in overcoming barriers to health promotion behavior. Conclusions. Future researchers must consider the confounding effects of exposure to violence when investigating differences in health promotion behaviors for low-income black and Latino groups. Community empowerment programs that address the impact of violence and focus on developing control over life and health outcomes may be needed to successfully address the effect of violence on health promotion behavior in low-income, black and Latino communities.
Three-dimensional (3D) geometric morphometric analysis of human premolars to assess sexual dimorphism and biological ancestry in Australian populations.

OBJECTIVES This study aimed to investigate size and shape variation of human premolars between Indigenous Australians and Australians of European ancestry, and to assess whether sex and ancestry could be differentiated between these groups using 3D geometric morphometrics. MATERIALS AND METHODS Seventy dental casts from each group, equally subdivided by sex, were scanned using a structured-light scanner. The 3D meshes of upper and lower premolars were processed using geometric morphometric methods. Seventy-two landmarks were recorded for upper premolars and 50 landmarks for lower premolars. For each tooth type, two-way ANOVA was used to assess group differences in centroid size. Shape variations were explored using principal component analysis and visualized using 3D morphing. Two-way Procrustes ANOVA was applied to test group differences for ancestry and sex, and a "leave-one-out" discriminant function was applied to assess group assignment. RESULTS Centroid size and shape did not display significant difference between the sexes. Centroid size was larger in Indigenous Australians for upper premolars and lower second premolars compared to the Australians of European ancestry. Significant shape variation was noted between the two ancestral groups for upper premolars and the lower first premolar. Correct group assignment of individual teeth to their ancestral groups ranged between 80.0 and 92.8% for upper premolars and 60.0 and 75.7% for lower premolars. DISCUSSION Our findings provide evidence of significant size and shape variation in human premolars between the two ancestral groups. High classification rates based on shape analysis of upper premolars highlight potential application of geometric morphometrics in anthropological, bioarcheological and forensic contexts.
Clinical features associated with mutations in the chromosome 1 open-angle glaucoma gene (GLC1A)

BACKGROUND A substantial proportion of cases of glaucoma have a genetic basis. Mutations causing glaucoma have been identified in the chromosome 1 open-angle glaucoma gene (GLC1A), which encodes a 57-kd protein known as myocilin. The normal role of this protein and the mechanism by which mutations cause glaucoma are not known. METHODS We screened 716 patients with primary open-angle glaucoma and 596 control subjects for sequence changes in the GLC1A gene. RESULTS We identified 16 sequence variations that met the criteria for a probable disease-causing mutation because they altered the predicted amino acid sequence and they were found in one or more patients with glaucoma, in less than 1 percent of the control subjects. These 16 mutations were found in 33 patients (4.6 percent). Six of the mutations were found in more than 1 subject (total, 99). Clinical features associated with these six mutations included an age at diagnosis ranging from 8 to 77 years and maximal recorded intraocular pressures ranging from 12 to 77 mm Hg. CONCLUSIONS A variety of mutations in the GLC1A gene are associated with glaucoma. The spectrum of disease can range from juvenile glaucoma to typical late-onset primary open-angle glaucoma.
Optimization of Fiber Coatings to Minimize Stress Concentrations in Composite Materials

In this article we utilize a concentric cylinder model to analyze the stress state in a continuously reinforced coated fiber composite subjected to transverse loading. We incorporate this analysis into a methodical approach to determine an optimal inter phase coating for the fibers to maximize the composite's transverse strain to failure. The present study focuses on the effect of interphase Young's modulus on the stress state in the matrix material of a composite subjected to constant strain (displacement) boundary con ditions. We demonstrate, by analytically varying the coating modulus, that an optimum in terphase property exists which minimizes the maximum principal stress and the strain en ergy density in the composite material. The minimization of these quantities clearly indicates that failure initiation in a composite with an optimal fiber coating will occur at a significantly larger strain level. Therefore, we postulate (based on the current analysis) that the transverse strain to failure of a composite system can be increased with appropriate fiber coatings. Results and design curves are presented for an AS-4/Epon 828 composite system which suggest that for large fiber volume fractions (i.e., 60%) the optimum coating is an elastomeric material. The data presented on this composite suggest that the strain to failure can be increased as much as 6 times by coating the structural fibers with an optimal coating. A comparison between constant stress boundary conditions (i.e., optimizing strength) and constant strain boundary conditions (i.e., optimizing strain to failure) are also presented.
Intracoronary KAI-9803 as an Adjunct to Primary Percutaneous Coronary Intervention for Acute ST-Segment Elevation Myocardial Infarction

Background— KAI-9803, a &dgr;-protein kinase C inhibitor, has been shown to ameliorate injury associated with ischemia and reperfusion in animal models of acute myocardial infarction (MI). Methods and Results— Direct Inhibition of &dgr;-Protein Kinase C Enzyme to Limit Total Infarct Size in Acute Myocardial Infarction (DELTA MI) was a “first-in-human,” dose-escalation study that evaluated the safety, tolerability, and activity of KAI-9803 for patients with acute anterior ST-segment elevation MI undergoing primary percutaneous coronary intervention. Patients who presented within 6 hours of symptom onset and had an occluded left anterior descending infarct artery on angiography were randomized in a 2:1 fashion to receive 1 of 4 doses of KAI-9803 (cohort 1, 0.05 mg; cohort 2, 0.5 mg; cohort 3, 1.25 mg; cohort 4, 5.0 mg) versus blinded concurrent placebo delivered in 2 divided doses via intracoronary injection before and after reestablishment of antegrade epicardial flow with percutaneous coronary intervention. Safety and biomarker end points were assessed. Overall, 154 patients were randomized and treated with study drug (37 in cohort 1, 38 in cohort 2, 38 in cohort 3, 41 in cohort 4). The incidence of serious adverse events was similar between patients treated with KAI-9803 versus placebo. Other safety end points, including changes in QT intervals and standard laboratory values after study drug administration, were similar between treatment groups. Although the study was not powered to demonstrate efficacy with the biomarker end points assessed, signs of drug activity with KAI-9803 were suggested by trends for consistent, nonsignificant reductions in creatine kinase-MB area under the curve and ST-recovery area under the curve values across all dosing cohorts with KAI-9803 compared with concurrent placebo, and similar trends were demonstrated for improvements in 99mtechnetium sestamibi infarct size values with active study drug in cohorts 1, 2, and 3. Conclusions— KAI-9803 had an acceptable safety and tolerability profile when delivered via intracoronary injection during primary percutaneous coronary intervention for ST-segment elevation MI. Signs of potential drug activity were demonstrated with biomarker end points in this small exploratory study, indicating that further testing of KAI-9803 as an adjunctive therapy for ST-segment elevation MI is warranted.
The effect of microfibrillated cellulose addition on drying shrinkage and dimensional stability of wood-free paper

Microfibrillated cellulose (MFC) is known to enhance strength properties of paper. Improved strength usually means increased bonding which is strongly connected to dimensional instability of paper. The main objective of this work was to evaluate the dimensional stability of wood-free paper containing different amounts of varying grades of MFC and the effect MFC has with starch. Another important area was to develop a preparation method to produce sheets containing MFC. These sheets were dried using diverse methods to examine how drying strains induced by restraint drying affected hygroexpansion. The obtained results were compared to the results of the sheets containing kraft fines, and in specific test points cationic starch was used together with MFC. Tensile strength was also measured to study the type of bonding. Allowed shrinkage during drying had a significant effect on hygroexpansion. MFC decreased the dimensional stability of the freely dried sheets, but that of the restraint dried ones remained almost constant. As the amounts of MFC increased, the effects on dimensional stability became more severe. However, the fineness of MFC did not play an important role in dimensional stability. Both hygroexpansion and drying shrinkage were decreased with a cationic starch addition. The prevention of drying shrinkage produced sheets with similar hygroexpansion despite the type and amount of additives. For the restraint dried sheets, the tensile strength improved up till 7% addition. The combination of MFC and starch produced a sheet with improved dimensional stability and strength properties.
