description: Logistic regression is an algorithm widely used for binary classification in various real-world applications such as fraud detection, medical diagnosis, and recommendation systems. However, training a logistic regression model with data from different parties raises privacy concerns. Secure Multi-Party Computation (MPC) is a cryptographic tool that allows multiple parties to train a logistic regression model jointly without compromising privacy. The efficiency of the online training phase becomes crucial when dealing with large-scale data in practice. In this paper, we propose an online efficient protocol for privacy-preserving logistic regression based on Function Secret Sharing (FSS). Our protocols are designed in the two non-colluding servers setting and assume the existence of a third-party dealer who only poses correlated randomness to the computing parties. During the online phase, two servers jointly train a logistic regression model on their private data by utilizing pre-generated correlated randomness. Furthermore, we propose accurate and MPC-friendly alternatives to the sigmoid function and encapsulate the logistic regression training process into a function secret sharing gate. The online communication overhead significantly decreases compared with the traditional secure logistic regression training based on secret sharing. We provide both theoretical and experimental analyses to demonstrate the efficiency and effectiveness of our method.

R. H. Bland and the Port Phillip and Colonial Gold Mining Company
Creators: name: Woodland, John George
Publisher: name: La Trobe

description: There are numerous histories of the Victorian goldfields, individual digger's experiences, and the digging community as a whole. By contrast, very little has been written about the early gold mining companies. This thesis seeks to address this dearth in part, with a longitudinal study of one of the leading gold mining companies in nineteenth-century Victoria.The Port Phillip and Colonial Gold Mining Company ('Port Phillip Company') was one of many 'gold bubble' companies formed in England during 1851-3 to undertake gold mining in Australia. Within a few years it was the only survivor of this episode of British corporate gold-fever. The thesis argues that the influence of Rivett Henry Bland, the company's managing director, was instrumental in its success, particularly in its early years when faced with anti-company sentiment and unfavourable mining legislation.The company established a large-scale operation at Clunes in 1857, rapidly assuming a pre-eminent position in colonial gold mining with its superior technology and mining practices. Historians generally portray Australian gold mining operations as small, locally funded and inefficient, prior to British capital investment in the late 1880s. While true of the larger picture, this simply emphasises the uniqueness of the British-owned and funded Port Phillip Company, the largest and most efficient gold mining operation in Australia from 1857 until the early 1880s.The company and its investment offshoot, the Victoria (London) Mining Company, invested in over thirty Victorian gold mining companies during the 1860s. Again, this runs counter to the general view that British investment in Australian gold mining began only in the late 1880s. Although the two companies' investments equalled only a fraction of the later wave of British capital in absolute monetary terms, their contribution to the growth of the Victorian gold mining industry at the time was significant.

description: X-ray powder diffraction, electrical resistivity, magnetization, and thermodynamic measurements were conducted to investigate the structure and superconducting properties of TiHfNbTaMo, a novel high-entropy alloy possessing a valence electron count (VEC) of 4.8. The TiHfNbTaMo HEA was discovered to have a body-centered cubic structure and a microscopically homogeneous distribution of the constituent elements. This material shows type-II superconductivity with Tc = 3.42 K, lower critical field with 22.8 mT, and upper critical field with 3.95 T. Low-temperature specific heat measurements show that the alloy is a conventional s-wave type with a moderately coupled superconductor. First-principles calculations show that the density of states (DOS) of the TiHfNbTaMo alloy is dominated by hybrid d orbitals of these five metal elements. Additionally, the TiHfNbTaMo HEA exhibits three van Hove singularities. Furthermore, the VEC and the composition of the elements (especially the Nb elemental content) affect the Tc of the bcc-type HEA.

description: A classical question in spectral geometry is, for each pair of nonnegative integers $(p,n)$ such that $p\leq 2n$, if the eigenvalues of Laplacian on $p$-forms of a compact Kähler manifold are the same as those of $\mathbb{C}P^n$ equipped with the Fubini-Study metric, then whether or not this Kähler manifold is holomorphically isometric to $\mathbb{C}P^n$. For every positive even number $p$, we affirmatively solve this problem in all dimensions $n$ with at most two possible exceptions. We also clarify in this paper some gaps in previous literature concerned with this question, among which one is related to the volume estimate of Fano Kähler-Einstein manifolds.

The Integration of Laos into the International Economy: Global Production Sharing, Landlockedness, and Trade Costs

description: Laos is a developing country well-endowed with natural resources that faces development challenges due to high trade costs from being landlocked. This thesis examines the integration of Laos into the international economy, focusing on the role played by global production sharing and trade costs associated with landlockedness. Laos has opened up to the regional and global economy in order to overcome its locational disadvantage and to graduate from its status as a least developed country. As the world is increasingly characterised by the geographical dispersion of production, this offers opportunities for Laos to tap into certain segments of production sharing that are commensurate with its comparative advantage. A framework is developed, which is based on a gravity model, to analyse the factors affecting countries’ participation in global production sharing (or ‘networked trade’), with emphasis on the implications for landlocked countries. Controlling for economic size and geographical factors, landlocked status reduces networked trade (both for trade in parts and components, and final goods). However, reducing services links costs, in particular improved logistics performance and joining regional trade agreements, contributes to the expansion of networked trade. This highlights the importance for landlocked countries to improve services links that coordinate geographically dispersed production processes. In examining the role of firm-specific characteristics in influencing export performance, the findings suggest firm size, foreign ownership, and input imports have positive effects on firms’ export intensity. Larger firms have more resources to exploit economies of scale to enable them to export more. Having foreign equity and using imported inputs also help raise firms’ productivity through foreign expertise and networks. Case studies further reveal that although the Lao garment industry is relatively small compared to regional comparators, the electronics industry shows promising prospects given its recent strong growth. The absence of supporting industries in these sectors highlights the challenge that Laos faces in competing with neighbouring countries given the cost and time penalty associated with being landlocked. The current study makes a strong case for Laos to focus efforts on upgrading trade-related logistics, deepening regional economic integration, and improving the overall business environment. Such measures suggest Laos can overcome its natural disadvantage of being landlocked, which would help the country further integrate into the international economy and facilitate a smooth transition after Laos graduates from least developed country status.

description: With the advances of deep learning techniques, text generation is attracting increasing interest in the artificial intelligence (AI) community, because of its wide applications and because it is an essential component of AI. Traditional text generation systems are trained in a supervised way, requiring massive labeled parallel corpora. In this paper, I will introduce our recent work on search and learning approaches to unsupervised text generation, where a heuristic objective function estimates the quality of a candidate sentence, and discrete search algorithms generate a sentence by maximizing the search objective. A machine learning model further learns from the search results to smooth out noise and improve efficiency. Our approach is important to the industry for building minimal viable products for a new task; it also has high social impacts for saving human annotation labor and for processing low-resource languages.

description: This paper critically appraises the approaches that have characterized the literature on the macroeconomic effects of job reallocations. Since Lilien's (1982) seminal contribution there has been a flourishing of empirical analysis but no unifying theoretical framework has obtained consensus in the scientific debate. We face a corpus of research which is heterogeneous in variables' selection and experimental design. This heterogeneity makes the evaluation of results a daunting task. As a guiding principle for our excursion we track down the methodological development of the solutions to the crucial problem of observational equivalence of aggregate and sectoral reallocation shocks. We draw two main conclusions from our analysis.
The first is that the non-directional nature of reallocation shocks holds the key to the solution of the fundamental identification problem. In this sense the recent perspective on job creation and destruction shows much promise. The second conclusion is that sectoral reallocation of labor has been responsible for no less that 1/4 and no more that 2/3 of the variance of aggregate unemployment in postwar data. While this range may seem wide it is an indication that the importance of labor reallocation may have changed over time, being quite large at particular historical junctures.

description: Failure to recycle valuable metals from lithium-ion batteries (LIBs) could directly lead to various environmental issues, such as ecological toxicity with inevitable impacts on environment and society health. This study presents a green process for selective recovery of Li from spent LIBs based on a ternary deep eutectic solvent. The effects of solid-to-liquid ratio, temperature, and variations of deep eutectic solvent (DES) component concentrations on the selectivity of the leaching process were studied. A ternary DES based on choline chloride, urea and ethylene glycol was found to be more selective than conventional binary DESs and made it possible to extract the Li in the lower temperatures (75–100°C). In such temperatures, DESs present better viscosity and higher stability. In the optimum conditions, 92.83%, 1.61%, 0.72%, and 0.42% recoveries were obtained for Li, Co, Ni, and Mn, respectively. Kinetic modeling indicates that mixed control models were best fitted to all data. Moreover, the results indicated that the activation energy for Li extraction is 21.15 KJ/mol. Pearson correlation assessment relieved that L/S was the most effective factor with a positive impact (r > +0.5) on Li recovery among all variables. Furthermore, temperature impacts the selectivity of the leaching process. The illustrated selectivity coupled with biodegradability and the possibility of re-utilization of the DESs opens a novel way for the greener recovery of values from wastes.

description: The electronic structure of vanadium measured by Angular Correlation of electron-positron Annihilation Radiation (ACAR) is compared with the predictions of the combined Density Functional and Dynamical Mean-Field Theory (DMFT). Reconstructing the momentum density from five 2D projections we were able to determine the full Fermi surface and found excellent agreement with the DMFT calculations. In particular, we show that the local, dynamic self-energy corrections contribute to the anisotropy of the momentum density and need to be included to explain the experimental results.

description: Spinor fields on 5-dimensional Lorentzian manifolds are classified, according to the geometric Fierz identities that involve their bilinear covariants. Based upon this classification that generalises the celebrated 4-dimensional Lounesto classification of spinor fields, new non-trivial classes of 5-dimensional spinor fields are, hence, found, with important potential applications regarding bulk fermions and their subsequent localisation on brane-worlds. In addition, quaternionic bilinear covariants are used to derive the quaternionic spin density, through the truncated exterior bundle. In order to accomplish a realisation of these new spinors, a Killing vector field is constructed on the horizon of 5-dimensional Kerr black holes. This Killing vector field is shown to reach the time-like Killing vector field at the spatial infinity, through a current 1-form density, constructed with the derived new spinor fields. The current density is, moreover, expressed as the fünfbein components, assuming a condensed form.

description: The purpose of this study was to determine factors and characteristics associated with changes in knowledge among adults receiving education within the first 8 weeks post-concussion. The study also aimed to understand desired preferences (i.e. content, format) for education post-concussion from the perspective of patients and physicians. Patient-participants (17–85 years) were prospectively recruited within one week of a concussion. Participants received education over visits from Weeks 1 to 8 post-injury. Primary outcome measures were participant responses on a concussion knowledge questionnaire at Weeks 1 (n = 334) and 8 (n = 195), and feedback regarding education through interviews. Other variables collected included preexisting medical history, physician assessed recovery and symptoms. There was a significant increase in average knowledge on the concussion knowledge questionnaire across time (71% vs 75% correct; p = 0.004). Participants with higher levels of education, female sex and preexisting diagnoses of depression or anxiety had more correct responses at Week 1. Healthcare providers had varying comfort levels addressing mood-related symptoms. There is a need to tailor education provided to concussion patients based on preinjury characteristics, i.e., mood disorders and demographic factors. Healthcare providers may need additional training in addressing mood symptoms and should modify the approach to fit patients’ unique needs.

description: We prove homogenization for elliptic long-range operators in the random conductance model on random stationary point processes in d dimensions with Dirichlet boundary conditions and with a jointly stationary coefficient field. Doing so, we identify 4 conditions on the point process and the coefficient field that have to be fulfilled at different stages of the proof in order to pass to the homogenization limit. The conditions can be clearly attributed to concentration of support, Rellich--Poincaré inequality, non-degeneracy of the homogenized matrix and ergodicity of the elliptic operator.

description: Background: In Gia Lai province, from October 2013 to July 2014, 108 suspected diphtheria cases were reported in 13 out of 14 communes in the K’bang district of Gia Lai. Seven out of sixteen cases were confirmed positive with diphtheria. The current investigation found that  87% cases had not vaccinated with DPT while the expected coverage of DPT vaccination was 94%. The study aimed to estimate the DPT immunization coverage rate of children 1 to 5 years old and identify associated factors in this district in 2015.

Conclusions: This study shows that a significant gap exists between the observed vaccination coverage (81%) and the goal immunization coverage rate (98%). Groups that need specific attention ethnic minorities and those who are not registered at communal health centers. This study suggests that many parents do not get their children vaccinated because of a lack of understanding and educations campaigns should be introduced to improve vaccination uptake.

description: Detection of blazar pc scale counter-jets is difficult, but it can provide invaluable insight into the relativistic effects, radiative processes and the complex mechanisms of jet production, collimation and accelation in blazars. We build on recent populations models (optimized using the MOJAVE apparent velocity and redshift distributions) in order to derive the distribution of jet-to-counter-jet ratios and the flux densities of the counter-jet at different frequencies, in an effort to set minimum sensitivity limits required for existing and future telescope arrays in order to detect these elusive counter-jets. We find that: for the BL Lacs $5\%$ of their counter-jets have a flux-density higher than 100mJy, $15\%$ are higher than 10 mJy, and $32\%$ have higher flux-density than 1 mJy, whereas for the FSRQs $8\%$ have a flux-density higher than 10mJy, $17\%$ are higher than 1 mJy, and $32\%$ are higher than 0.1 mJy (at 15 GHz). Future telescopes like the SKA and newly operating like e-MERLIN and JVLA may detect up to $99\%$ of the BL Lac and $77\%$ of the FSRQ counter-jets. Sources with both low apparent velocity and a low Doppler factor make prime candidates for counter-jet detection. Combining our findings with literature values we have identified five such counter-jet detection candidates. Finally, we discuss possible effects beyond relativistic deboosting that may complicate the detection of counter-jets and that need to be accounted for in the interpretation of detections.

description: Pediatric cancer survivors (PCS) experience functional difficulties and brain alterations. However, little is known about cerebral perfusion and its relationship to functional outcome (cognitive and motor performance) in PCS. We examined cerebral blood flow (CBF) in non-brain tumor PCS and the associations between CBF and age, as well as functional outcome. Forty PCS and 40 age-comparable controls were included. CBF did not differ between PCS and controls. CBF decreased with age only in controls. In PCS, CBF was associated with functional outcome. Our data indicate an altered relationship between age and CBF in survivors, with stronger brain-behavior mechanisms after cancer.

description: We discuss how x-ray Compton scattering spectra can be used for investigating the evolution of electronic states in cathode materials of Li batteries under the lithiation/delithiation process. In particular, our analysis of the Compton spectra taken from polycrystalline LixCoO2 samples shows that the spectra are dominated by the contribution of the O-2p redox orbital. We identify a distinct signature of d-orbital delocalization, which is tied directly to the conductivity of the material, providing a descriptor based on Compton spectra for monitoring the lithiation range with improved conductivity and kinetics for electrochemical operation. Our study demonstrates that Compton scattering spectroscopy can provide a window for probing complex electronic mechanisms underlying the charging and discharging processes in Li-battery materials.

description: We employ population synthesis method to model the double neutron star (DNS) population and test various possibilities on natal kick velocities gained by neutron stars after their formation. We first choose natal kicks after standard core collapse SN from a Maxwellian distribution with velocity dispersion of sigma=265 km/s as proposed by Hobbs et al. (2005) and then modify this distribution by changing the velocity dispersion towards smaller and larger kick values. We also take into account the possibility of NS formation through electron capture supernova. In this case we test two scenarios: zero natal kick or small natal kick, drawn from Maxwellian distribution with sigma = 26.5 km/s. We calculate the present-day orbital parameters of binaries and compare the resulting eccentricities with those known for observed DNSs. As an additional test we calculate Galactic merger rates for our model populations and confront them with observational limits. We do not find any model unequivocally consistent with both observational constraints simultaneously.The models with low kicks after CCSN for binaries with the second NS forming through core collapse SN are marginally consistent with the observations. This means that either 14 observed DNSs are not representative of the intrinsic Galactic population, or that our modeling of DNS formation needs revision.

description: The general relativistic formulation of the problem of magnetically confined mountains on neutron stars is presented, and the resulting equations are solved numerically, generalising previous Newtonian calculations. The hydromagnetic structure of the accreted matter and the subsequent magnetic burial of the star's magnetic dipole moment are computed. Overall, it is observed that relativistic corrections reduce the hydromagnetic deformation associated with the mountain. The magnetic field lines are curved more gently than in previous calculations, and the screening of the dipole moment is reduced. Quantitatively, it is found that the dimensionless dipole moment ($m_{\rm d}$) depends on the accreted mass ($M_{\rm a}$) as $m_{\rm d} = -3.2\times10^{3}M_{\rm a}/M_\odot + 1.0$, implying approximately three times less screening compared to the Newtonian theory. Additionally, the characteristic scale height of the mountain, governing the gradients of quantities like pressure, density, and magnetic field strength, reduces by approximately $40\%$ for an isothermal equation of state.

description: Low-dose nitrogen implantation induces in TiO2 nanotubes a co-catalytic activity for photocatalytic H2-evolution. The use of an ion implantation process leads to a N-implanted zone only at the top part of the tubes. The coupling of this top layer and the underlying non-implanted part of the nanotubes strongly contributes to an efficient carrier separation and thus to a significantly enhanced H2 generation.

description: A qualitative study in East Arnhem Land (EAL), Northern Territory of Australia, was conducted with 22 Yolŋu participants in seven remote communities in EAL between June 2014 and September 2015, with the support of one female and one male Cultural Mentor. The research sought to determine whether tobacco-control efforts utilising denormalisation had resulted in experiences of smoking-related stigma, as an unintended consequence. The role of Yolŋu smokefree leaders in remote communities was also investigated and the Tackling Indigenous Smoking (TIS) program, ‘Yaka Ŋarali’’ was evaluated to determine engagement and acceptance by Yolŋu smokers and their families. We found that the Yaka Ŋarali’ program had achieved significant impact and acceptance in the region, that there was strong smokefree leadership among Health Service employees and that despite the close traditional relationship with ŋarali’ [tobacco], Yolŋu were willing to participate and engage with denormalisation approaches, with little evidence of smoking-related stigma. All participants (community members and health staff, smokers and non-smokers) were concerned about protecting children from second-hand smoke, and wished to prevent their children and families from smoking. Tobacco Action Workers were considered the ‘right people with the right message’ to offer leadership about smoking and tobacco control. Yolŋu Health Workers regularly advised clients, family and community members to quit smoking, irrespective of their own smoking status. The study confirmed that some clinical consultations and interactions may have led to feelings of smoking-related shame among Yolŋu Health Workers who smoked, however a caring, trusting relationship with offers of help enabled the issue of smoking to be raised without causing shame. The study also confirmed that the Yolŋu did not wish to put aside their valued and traditional connection to ŋarali’ (tobacco), an important part of the sacred practices of funeral ceremony.

description: Optical depths of dense molecular gas are commonly used in Galactic and extragalactic studies to constrain the dense gas mass of the clouds or galaxies. The optical depths are often obtained based on spatially unresolved data, especially in galaxies, which may affect the reliability of such measurements. We examine such effects in spatially resolved Galactic massive star-forming regions. Using the 10-m SMT telescope, we mapped HCN and H13CN 3-2, HCO+, and H13CO+ 3-2 towards 51 Galactic massive star-forming regions, 30 of which resulted in robust determination of spatially resolved optical depths. Conspicuous spatial variations of optical depths have been detected within each source. We first obtained opacities for each position and calculated an optical-thick line intensity-weighted average, then averaged all the spectra and derived a single opacity for each region. The two were found to agree extremely well, with a linear least square correlation coefficient of 0.997 for the whole sample.

description: The aim of this study was to compare vastus lateralis (VL) and rectus femoris (RF) muscles for their nervous and mechanical adaptations during two bouts of downhill walking (DW) with load carriage performed two weeks apart. Moreover, we investigated cardio-metabolic and perceived exertion responses during both DW bouts. Methods Seventeen participants performed two 45-min sessions of loaded DW (30% of body mass; slope: -25 %; speed: 4.5 km$\times$h -1 ) separated by two weeks. Rating of perceived exertion (RPE), cost of walking (C w ), heart rate (HR), and EMG activity of thigh muscles were assessed during the DW. Muscle shear elastic modulus ($μ$) of RF and VL were assessed before each exercise bout. Maximal voluntary contraction (MVC) torque was assessed before (PRE), immediately after (POST), 24 and 48 h after the two exercise bouts. Results MVC torque decreased from POST (-23.7 $\pm$ 9.2%) to 48 h (-19.2 $\pm$ 11.9%) after the first exercise (Ex1), whereas it was significantly reduced only at POST (-14.6 $\pm$ 11.0%) after the second exercise (Ex2) (p < 0.001). RPE (Ex1: 12.3 $\pm$ 1.9; Ex2: 10.8 $\pm$ 2.0), HR (Ex1: 156 $\pm$ 23 bpm; Ex2: 145 $\pm$ 25 bpm), C w (Ex1: 4.5 $\pm$ 0.9 J$\times$m -1 $\times$kg -1 ; Ex2: 4.1 $\pm$ 0.7 J$\times$m -1 $\times$kg -1 ) and RF EMG activity (Ex1: 0.071 $\pm$ 0.028 mV; Ex2: 0.041 $\pm$ 0.014 mV) were significantly decreased during Ex2 compared to Ex1 (p < 0.01). RF $μ$ was significantly greater in Ex2 (0.44 $\pm$ 0.18) compared to Ex1 (0.56 $\pm$ 0.27; p < 0.001). Conclusions The RF muscle displayed specific mechanical and nervous adaptations to repeated DW bouts as compared to VL. Moreover, the muscle adaptations conferred by the first bout of DW could have induced greater exercise efficiency, inducing lesser perceived exertion and cardio-metabolic demand when the same exercise was repeated two weeks later.

description: The artistic style of a painting is a subtle aesthetic judgment used by art historians for grouping and classifying artwork. The recently introduced `neural-style' algorithm substantially succeeds in merging the perceived artistic style of one image or set of images with the perceived content of another. In light of this and other recent developments in image analysis via convolutional neural networks, we investigate the effectiveness of a `neural-style' representation for classifying the artistic style of paintings.

description: The effective mirror area of an imaging atmospheric Cherenkov telescope is a crucial key parameter for trigger threshold determination and energy calibration. It is usually calculated by 3D ray-tracing simulation using a simplified telescope model, and the result is used in Monte Carlo simulations. However, simplified telescope and camera models are not adequate for the Schwarzschild-Couder configuration to be used in Small-Sized Telescopes (SSTs) of the Cherenkov Telescope Array. This is because the complex 3D structure of the secondary mirror, telescope masts, and camera body block a significant fraction of Cherenkov and night-sky photons. To evaluate the effective mirror area of an SST and to finalize its camera body design with minimal shadowing, a complex 3D model was built and simulated using the ROBAST ray-tracing library. A camera body size of 570 mm and a window size of 430 mm were selected for the final camera design based on the evaluation of shadowing by simulation. A non-axisymmetric effective area distribution was determined via the modeling of the complex telescope structure, while meeting the SST effective area requirement.

description: We show existence and uniqueness of very weak solutions of the Cauchy problem for the porous medium equation on Cartan-Hadamard manifolds satisfying suitable lower bounds on Ricci curvature, with initial data that can grow at infinity at a prescribed rate, that depends crucially on the curvature bounds. The curvature conditions we require are sharp for uniqueness in the sense that if they are not satisfied then, in general, there can be infinitely many solutions of the Cauchy problem even for bounded data. Furthermore, under matching upper bounds on sectional curvatures, we give a precise estimate for the maximal existence time, and we show that in general solutions do not exist if the initial data grow at infinity too fast. This proves in particular that the growth rate of the data we consider is optimal for existence. Pointwise blow-up is also shown for a particular class of manifolds and of initial data.

description: In this paper, we have investigated, using finite element calculations, the effect of initial texture on the formation of multiple necking patterns in ductile metallic rings subjected to rapid radial expansion. The mechanical behavior of the material has been modeled with the elasto-viscoplastic single crystal constitutive model developed by \citet{marin2006}. The polycrystalline microstructure of the ring has been generated using random Voronoi seeds. Both $5000$ grain and $15000$ grain aggregates have been investigated, and for each polycrystalline aggregate three different spatial distributions of grains have been considered. The calculations have been performed within a wide range of strain rates varying from $1.66 \cdot 10^4 ~ \text{s}^{-1}$ to $3.33 \cdot 10^5 ~ \text{s}^{-1}$, and the rings have been modeled with four different initial textures: isotropic texture, $\left\langle 001\right\rangle\parallelΘ$ Goss texture, $\left\langle 001\right\rangle\parallel$ R Goss texture and $\left\langle 111\right\rangle\parallel$ Z fiber texture. The finite element results show that: (i) the spatial distribution of grains affects the location of the necks, (ii) the decrease of the grain size delays the formation of the necking pattern and increases the number of necks, (iii) the initial texture affects the number of necks, the location of the necks, and the necking time, (iv) the development of the necks is accompanied by a local increase of the slip activity. This work provides new insights into the effect of crystallographic microstructure on dynamic plastic localization and guidelines to tailor the initial texture in order to delay dynamic necking formation and, thus, to improve the energy absorption capacity of ductile metallic materials at high strain rates.
