Beyond Sharing Weights for Deep Domain Adaptation

description: The performance of a classifier trained on data coming from a specific domain typically degrades when applied to a related but different one. While annotating many samples from the new domain would address this issue, it is often too expensive or impractical. Domain Adaptation has therefore emerged as a solution to this problem; It leverages annotated data from a source domain, in which it is abundant, to train a classifier to operate in a target domain, in which it is either sparse or even lacking altogether. In this context, the recent trend consists of learning deep architectures whose weights are shared for both domains, which essentially amounts to learning domain invariant features. Here, we show that it is more effective to explicitly model the shift from one domain to the other. To this end, we introduce a two-stream architecture, where one operates in the source domain and the other in the target domain. In contrast to other approaches, the weights in corresponding layers are related but not shared. We demonstrate that this both yields higher accuracy than state-of-the-art methods on several object recognition and detection tasks and consistently outperforms networks with shared weights in both supervised and unsupervised settings.

description: We investigate the extent to which artificial intelligence (AI) is harnessed by regions for specializing in green technologies. By considering the transformative role that AI is playing in the invention process and connecting it to the regional development of environmental technologies, we examine the relationship between green-revealed technological advantages and local AI for EU-28 (NUTS-3) regions over the period 1982–2017. Results show that AI knowledge favours the green-tech specialization of regions, provided that they were already green-tech specialized in the past. Conversely, AI even reduces this capacity in regions that have not already specialized in green technologies.

description: Photoluminescence provides experimental access to magnitudes most relevant for quantum solar
energy conversion, such as spectral absorption, defect densities, and in particular to excess carrier densities which
can be translated into splitting of quasi-Fermi levels. For the evaluation of these date from experiments the
interaction of the luminescence photon flux in the absorber and at its interfaces has to be considered, means generally
propagation, attenuation, transfer across phase boundaries and corresponding reflection, as well as photon recycling
has to be included. For multilayer systems glass substrate/CIGSe-absorber/CdS-window layer we have calculated the
luminescence reaching the detector with a 1D matrix transfer formalism. Light entrance side has been chosen through
the CdS-window as well as through the glass substrate. For excess carrier depth profile forming the basis for the
luminescence by radiative recombination we introduce a carrier generation profile calculated via 1D steady state
continuity equation. We analyze the influence of minority diffusion lengths and surface recombination (LD, Sd, S0) on
the spectral shape of the luminescence yield and discuss the suitability for the extraction of the splitting of quasi-
Fermi levels which in solar cell absorbers limits the potential open circuit of finally processed diodes. Comparison of
numerically simulated spectral luminescence with experimental data recorded e.g. in a confocal setup allows for a
consistent interpretation of luminescence results and for the estimation of excess carrier depth profiles.

description: The cryptocurrency ecosystem has been the centre of discussion on many social media platforms, following its noted volatility and varied opinions. Twitter is rapidly being utilised as a news source and a medium for bitcoin discussion. Our algorithm seeks to use historical prices and sentiment of tweets to forecast the price of Bitcoin. In this study, we develop an end-to-end model that can forecast the sentiment of a set of tweets (using a Bidirectional Encoder Representations from Transformers - based Neural Network Model) and forecast the price of Bitcoin (using Gated Recurrent Unit) using the predicted sentiment and other metrics like historical cryptocurrency price data, tweet volume, a user's following, and whether or not a user is verified. The sentiment prediction gave a Mean Absolute Percentage Error of 9.45%, an average of real-time data, and test data. The mean absolute percent error for the price prediction was 3.6%.

description: Industrial policy based on Smart Specialisation emphasizes the exploitation of industrial linkages based on technological rather than intermediate product linkages. This paper develops microlevel analysis using the Organisation for Economic Co-operation and Development’s (OECD) patent citation database on the intensity of technical relatedness depending on the cited and citing technological fields. The results are used to estimate the patterns of interregional knowledge spillovers in the European Union and explain spatial differences in patent growth. The approach to identifying spillovers provides an improved toolbox to guide implementation of Smart Specialisation policies.
Nonequilibrium Anderson model made simple with density functional theory

description: The single-impurity Anderson model is studied within the i-DFT framework, a recently proposed extension of density functional theory (DFT) for the description of electron transport in the steady state. i-DFT is designed to give both the steady current and density at the impurity, and it requires the knowledge of the exchange-correlation (xc) bias and on-site potential (gate). In this work we construct an approximation for both quantities which is accurate in a wide range of temperatures, gates and biases, thus providing a simple and unifying framework to calculate the differential conductance at negligible computational cost in different regimes. Our results mark a substantial advance for DFT and may inform the construction of functionals applicable to other correlated systems.

description: The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a transition stage and shows many intriguing structures both in scattered light and thermal (sub-)millimeter emission which are possibly related to planet formation processes. We study the morphology and surface brightness of the disk in scattered light to gain insight into the innermost disk regions, the formation of protoplanets, planet-disk interactions traced in the surface and midplane layers, and the dust grain properties of the disk surface. We have carried out high-contrast polarimetric differential imaging (PDI) observations with VLT/SPHERE and obtained polarized scattered light images with ZIMPOL in R- and I-band and with IRDIS in Y- and J-band. The scattered light images reveal with unprecedented angular resolution and sensitivity the spiral arms as well as the 25 au cavity of the disk. Multiple shadow features are discovered on the outer disk with one shadow only being present during the second observation epoch. A positive surface brightness gradient is observed in the stellar irradiation corrected images in southwest direction possibly due to an azimuthally asymmetric perturbation of the temperature and/or surface density by the passing spiral arms. The disk integrated polarized flux, normalized to the stellar flux, shows a positive trend towards longer wavelengths which we attribute to large aggregate dust grains in the disk surface. Part of the the non-azimuthal polarization signal in the Uphi image of the J-band observation could be the result of multiple scattering in the disk. The detected shadow features and their possible variability have the potential to provide insight into the structure of and processes occurring in the innermost disk regions.

Molekulare Veränderungen des Tumorrandes und der Tumor benachbarten Gewebe könnten in Ergänzung zur Histopathologie eine kurative chirurgische Tumorextirpation bestätigen. Wir untersuchten die Telomeraseaktivität in verschiedenen Entfernungen vom Tumorzentrum um ihre Verwendung als molekularen Marker zu prüfen. Wir untersuchten 80 kryokonservierte Gewebeschnitte von 40 Patienten mit einem Plattenepithelkarzinom im Kopf-Hals-Bereich, davon 33 karzinomfreie Tumorrandgewebe. 50% der 20 karzinomhaltigen Gewebe, 28 % der karzinomfreien Tumorrandgewebe und 35 % der tumorfernen Proben waren telomerasepositiv. Der Vergleich ergab keinen statistisch signifikanten Unterschied. Es konnte keine sichere Korrelation zwischen der Telomeraseaktivität in den untersuchten Geweben mit dem weiteren Krankheitsverlauf gefunden werden, allerdings zeigte die Telomerasepositivität in karzinomfreien Tumorrändern die Tendenz, mit einer besseren Prognose zu korrespondieren. Unsere Befunde sollten an einer größeren und homogeneren Patientengruppe überprüft werden.
description: Squamous cell carcinomas of the head-neck region are characterised by an aggressive course of disease and a strong tendency to loco-regional recurrence and second primary tumours. As a complement to histopathology, molecular changes of tumour marginal and tumor distant tissue may confirm curative surgical tumour extirpation. We tested telomerase activity at different distances to the tumour centre of squamous cell carcinomas to consider the use for molecular marker. We examined 80 cryo-conserved tissue samples from 40 patients with a squamous cell carcinoma of the head-neck region, among them 33 carcinoma-free margin tissues. 50 % of the carcinoma centres, 28 % of the carcinoma-free margin tissues and 35% of the tumour distant samples were telomerase-positive. The comparison showed no statistically significant difference. We have found no reliable correlation between telomerase activity in the carcinoma-free margin tissues and the further course of disease, but telomerase positivity in carcinoma-free tumour margins tended to correlate with a better prognosis. Confirmation of the results in a larger and more homogeneous patient group is needed.

description: Renewable energy sources, as photovoltaic (PV) energy, are meant to reduce human footprint by
cutting down emissions. In this framework, the application of the cradle-to-cradle principle where the waste becomes
food, is essential. It has been proven by other sectors already mature in recycling, that taking care of your end-of-life
products not only trims the costs of raw material but also cuts down on CO2 emissions. Moreover, valuable and rare
materials would be recovered and introduced in the life cycle again reducing then, the production costs and
emissions. However, in order to make the necessary investment in PV module recycling facilities, the continuous
flow of end-of-life modules is missing. In this framework, the main module producers and importers have created PV
CYCLE in 2007 to work on a voluntary take back and recycling system of photovoltaic modules in Europe. In this
paper, we will describe the ambitious goals of the PV CYCLE project, the experienced acquired during the start up
phase.

description: We present a new set of 95 numerical relativity simulations of non-precessing binary black holes (BBHs). The simulations sample comprehensively both black-hole spins up to spin magnitude of 0.9, and cover mass ratios 1 to 3. The simulations cover on average 24 inspiral orbits, plus merger and ringdown, with low initial orbital eccentricities $e<10^{-4}$. A subset of the simulations extends the coverage of non-spinning BBHs up to mass ratio $q=10$. Gravitational waveforms at asymptotic infinity are computed with two independent techniques, extrapolation, and Cauchy characteristic extraction. An error analysis based on noise-weighted inner products is performed. We find that numerical truncation error, error due to gravitational wave extraction, and errors due to the finite length of the numerical waveforms are of similar magnitude, with gravitational wave extraction errors somewhat dominating at noise-weighted mismatches of $\sim 3\times 10^{-4}$. This set of waveforms will serve to validate and improve aligned-spin waveform models for gravitational wave science.

description: Using a global dataset of over 840,000 equity, bond and syndicated loan investment banking deals, we build the fossil fuel investment brokerage profile of financial centres worldwide between 2000 and 2018. We also study whether city-level fossil fuel divestment commitments and country-level green banking policies impact the profile of fossil fuel financial centres over our study timeframe. We find that several financial centres shift their fossil fuel investment brokerage profiles substantially, including the asset classes in which they are active. However, we do not find any evidence that this is driven by city-level divestment commitments. In contrast, we find that fossil fuel investment banking brokers situated in financial centres exposed to voluntary green banking policies reduce their fossil fuel financing. This is driven by foreign brokers whose behaviour appears to signal an anticipation of forthcoming mandatory green finance policies.

description: In recent decades various digital artifacts have been integrated into our daily life. One such integration is chatbots or conversational agents like Siri and Alexa. Even though those devices are helping primarily in daily activities, they can potentially be used for medical and health care purposes. In our research, we tried to focus on the current trend of using conversational agents in daily life and potential ways of using those in the medical field. Primarily we focused on chatbot uses in dementia care. Within our work, we analyzed interviews from care facilities and referred to some other research articles to find potential ways of using chatbots in care facilities. As a prototype, we developed a chatbot that will act as a communication medium between caregivers and dementia patients. We also conducted an interview to explore further improvement areas of the chatbot.

description: We present a novel numerical method and algorithm for the solution of the 3D axially symmetric time-dependent Schrödinger equation in cylindrical coordinates, involving singular Coulomb potential terms besides a smooth time-dependent potential. We use fourth order finite difference real space discretization, with special formulae for the arising Neumann and Robin boundary conditions along the symmetry axis. Our propagation algorithm is based on merging the method of the split-operator approximation of the exponential operator with the implicit equations of second order cylindrical 2D Crank-Nicolson scheme. We call this method hybrid splitting scheme because it inherits both the speed of the split step finite difference schemes and the robustness of the full Crank-Nicolson scheme. Based on a thorough error analysis, we verified both the fourth order accuracy of the spatial discretization in the optimal spatial step size range, and the fourth order scaling with the time step in the case of proper high order expressions of the split-operator. We demonstrate the performance and high accuracy of our hybrid splitting scheme by simulating optical tunneling from a hydrogen atom due to a few-cycle laser pulse with linear polarization.

description: It was previously shown, that an additional low temperature (LT) anneal directly after phosphorus
diffusion improves the efficiency of multicrystalline solar cells made of border brick of a silicon ingot. We now
investigated different materials. The effect was not seen in the middle of the ingots, even not for upgraded
metallurgical silicon or for material with high densities of dislocations and grain boundaries. However, the positive
effect of the LT-anneal was again found, when the wafers were deteriorated from the crucible walls or its coating. To
find an optimum temperature, the LT-anneal was done on many neighbouring wafers using fine temperature steps of
25 °C between 300 °C and 800 °C. The best results were obtained at 575 °C. Detailed LBIC-measurements were
performed. Furthermore, the origin of the positive effect of the LT-anneal was investigated by removing the emitter
from some cells before the anneal. The LBIC-topograms as well as lifetime topograms show that this positive effect
is more likely due to phosphorus gettering than internal gettering.

description: The article invites readers to rethink cities in economic networks against the backdrop of the many ways in which ‘gateway cities’, serving as brokers, interlink their respective hinterlands globally. It adds logistics, industrial processing and knowledge transmission to the more established gateway dimensions of corporate control and related service provision. This open heuristic is applied to Buenos Aires (Argentina), Cape Town (South Africa) and Singapore, which are vital nodes for the oil and gas industry. In addition to showing how diverse brokerage by cities is, the article calls for qualitative research to complement the insights on city networks generated by quantitative assessments.

description: Toxicity represents a threat to the safety and health of online multiplayer gaming communities. This has been recognized by industry, academia, and players and led to efforts for combating toxicity, including different approaches for predicting toxicity from behaviour. Despite promising results, such approaches have not yet been able to meaningfully combat toxicity at scale. In this position paper, we describe four obstacles that impede usable applied toxicity prediction in multiplayer games that could help to combat harm.We want to foster a discussion about how user-centered artificial intelligence approaches may help solve these obstacles.
The 7.2/3 Years Collection of Well-Monitored Fermi-LAT GRB Afterglows
Creators: name: Panaitescu, A.
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We present the light-curves and spectra of 24 afterglows that have been monitored by Fermi-LAT at 0.1-100 GeV over more than a decade in time. All light-curves (except 130427) are consistent with a single power-law starting from their peaks, which occurred, in most cases, before the burst end. The light-curves display a brightness-decay rate correlation, with all but one (130427) of the bright afterglows decaying faster than the dimmer afterglows. We attribute this dichotomy to a quick deposition of the relativistic ejecta energy in the external-shock for the brighter/faster-decaying afterglows and to an extended energy-injection in the afterglow shock for the dimmer/slower-decaying light-curves. The spectra of six afterglows (090328, 100414, 110721, 110731, 130427, 140619B) indicate the existence of a harder component above a spectral dip/ankle at energy 0.3-3 GeV, offering evidence for an inverse-Compton emission at higher energies, and suggesting that the harder power-law spectra of five other LAT afterglows (130327B, 131231, 150523, 150627, 160509) could also be inverse-Compton, while the remaining softer LAT afterglows should be synchrotron. Marginal evidence for a spectral break and softening at higher energies is found for two afterglows (090902B and 090926).

description: Compared with monolithically stacked multi-junction (MMJ) solar cells, the approach of
mechanically stacking junctions offers some advantages, due to its unconstrained electrical interconnections. As a
result, mechanically stacked multi-junction (MSMJ) solar cells are less sensitive to spectral variations, and have a
high performance potential in terms of annual energy output. The detailed balance efficiency limits and theoretical
annual energy output of the two approaches are compared, which predicts an annual energy yield of 59.3% for
MSMJ cell and 43.8% for MMJ cell, with a bandgap combination of 1.87/1.41/0.67eV under 500x concentration at
Las Vegas. In practice, the first mechanically stacked InGaP-GaAs-Ge triple junction solar cells have also been
successfully realized. Although currently the performance of this triple-junction stack is still limited due to the
lower short-circuit currents of the lower two junctions, further optimization and reduction in optical losses are
expected to improve the mechanical stack performance.

description: We find a single parameter family of genuinely entangled three qubit pure states, called the maximally Bell inequality violating states (MBV), which exhibit maximum Bell inequality violation by the reduced bipartite system for a fixed amount of genuine tripartite entanglement quantified by the so called tangle measure. This in turn implies that there holds a complementary relation between the Bell inequality violation by the reduced bipartite systems and the tangle present in the three qubit states, not necessarily pure. The MBV states also exhibit maximum Bell inequality violation by the reduced bipartite systems of the three qubit pure states with a fixed amount of genuine tripartite correlation quantified by the generalized geometric measure, a genuine entanglement measure of multiparty pure states, and the discord monogamy score, a multipartite quantum correlation measure from information theoretic paradigm. The aforementioned complementary relation has also been established for three qubit pure states for the generalized geometric measure and the discord monogamy score respectively. The complementarity between the Bell inequality violation by the reduced bipartite systems and the genuine tripartite correlation suggests that the Bell inequality violation in the reduced two qubit system comes at the cost of the total tripartite correlation present in the entire system.

description: This study investigates the impact of local incumbent firms on new private firm formation in China by focusing on the cognitive legitimacy lent by different ownership types. We argue that new firm formation requires legitimacy spillover from local society. Based on the panel data of China’s manufacturing enterprises, we find that local ownership structure plays a vital role in new private firm formation. Incumbent privately owned enterprises enhance the legitimacy of private ownership naturally, and the effect from foreign-owned enterprises to new private firms is positive but weaker than that of privately owned enterprises, whereas state-owned enterprises discourage entrepreneurship due to their entirely different identities.

description: In this paper, we report on deposition and properties of high quality boron doped p-type amorphous
Si (a-Si:H(p)) layers on n-type float zone Si(100) wafers by remote linear radio frequency plasma-enhanced CVD.
The a-Si:H(p) layers show excellent surface passivation that is comparable to that of a-Si:H intrinsic layers (a-
Si:H(i)), and high stability of the passivation when stored in the dark. Additionally, the measured dark conductivity
of deposited a-Si:H(p) is increased up to >7´10-6 S/cm by annealing. In a Si heterojunction cell structure, the a-
Si:H(p) layer will be the emitter on an n-type base wafer. The effective lifetime of test structures of
a-Si(p)/c-Si(n)/a-Si(n) has approached 1 ms, and a high pseudo fill factor and open circuit voltage have been
obtained from a SunsVoc measurement. We conclude that these a-Si:H(p) layers are very promising for the
application in high performance silicon heterojunction solar cells without using an intermediate a-Si:H(i) layer.

description: In the thirty years since the end of real socialism, Bulgaria's went from having a rather radically 'different' tax system to adopting flat-rate taxation with marginal tax rates that fell from figures as high as 40% to 10% for both the corporate-income tax and the personal-income tax. Crucially, the econometric forecasting models in use at the Bulgarian Ministry of Finance hinted at an increase in tax revenue compatible with the so-called 'Laffer curve'. Similarly, many economists held the view that revenues would have increased. However, reality fell short of those expectations based on forecasting models and rooted in mainstream economic theory. Thus, this paper asks whether there are betterperforming forecasting models for personal-and corporate-income tax-revenues in Bulgaria that are readily implementable and overperform the ones currently in use. After articulating a constructive critique of the current forecasting models, the paper offers readily implementable, transparent alternatives and proves their superiority.

description: Brokers play a critical role in the evolution of innovation systems by accessing and diffusing external knowledge. However, while brokers’ activity allows benefits for the entire system, it entails costs for those who play the broker role. Using patent data to analyse inter-city networks in Latin America, we identify broker cities and estimate the effects of brokerage on patenting outcomes between 2006 and 2017. Our findings reveal that cities holding a central position in the network show higher patenting activity; however, being a broker, particularly connecting Latin American cities with the rest of the world, negatively influences patenting outcomes.

description: High-efficiency III-V concentrator solar cells are a viable option for utility-scale electricity production.
In this paper we report on the progress in developing a substrate removed In49.5Ga50.5P solar cell to be used in a
mechanically stacked multijunction solar cell. Excitation power dependent time-resolved photoluminescence
measurements on n-type In49.5Ga50.5P layers are performed resulting in a bulk lifetime of 0.55 ns for high excitation
and 0.29 ns for low excitation. Solar cell layers are grown lattice matched to germanium and with varying V/III ratio.
Cells are processed with or without substrate removal and their performance is compared. The best material quality is
obtained with high V/III ratio growth. Conversion efficiencies of 15.64 % and 16.70 % are reached for a 0.25 cm2 onsubstrate
and a 0.11 cm2 off-substrate cell, respectively.
Finite time blowup for a supercritical defocusing nonlinear wave system

description: We consider the global regularity problem for defocusing nonlinear wave systems $$ \Box u = (\nabla_{{\bf R}^m} F)(u) $$ on Minkowski spacetime ${\bf R}^{1+d}$ with d'Alambertian $\Box := -\partial_t^2 + \sum_{i=1}^d \partial_{x_i}^2$, the field $u: {\bf R}^{1+d} \to {\bf R}^m$ is vector-valued, and $F: {\bf R}^m \to {\bf R}$ is a smooth potential which is positive and homogeneous of order $p+1$ outside of the unit ball, for some $p >1$. This generalises the scalar defocusing nonlinear wave (NLW) equation, in which $m=1$ and $F(v) = \frac{1}{p+1} |v|^{p+1}$. It is well known that in the energy sub-critical and energy-critical cases when $d \leq 2$ or $d \geq 3$ and $p \leq 1+\frac{4}{d-2}$, one has global existence of smooth solutions (for dimensions $d \leq 7$ at least) from arbitrary smooth initial data $u(0), \partial_t u(0)$. In this paper we study the supercritical case where $d = 3$ and $p > 5$. We show that in this case, there exists smooth potential $F$ for some sufficiently large $m$ (in fact we can take $m=40$), positive and homogeneous of order $p+1$ outside of the unit ball, and a smooth choice of initial data $u(0), \partial_t u(0)$ for which the solution develops a finite time singularity. In fact the solution is discretely self-similar in a backwards light cone. The basic strategy is to first select the mass and energy densities of $u$, then $u$ itself, and then finally design the potential $F$ in order to solve the required equation. The Nash embedding theorem is used in the second step, explaining the need to take $m$ relatively large.

description: Recently the use of the mixture with wood fiber substrates for cultivation of vegetable transplants has received increasing attention. Several experiments were conducted to investigate the effect of water supply on bio-morphological and plant-physiological parameters of tomato transplants cultivated in pure wood fiber substrates in order to optimize cultivation. Optimal growth of transplants in these substrates requires high moisture levels. Comparing time-dependent with water-tension-dependent irrigation (φ = -30 hPa) showed that almost identical bio-morphological plant characteristics were achieved. In an ebb/flood system, irrigation pulses are recommended at φ = -30 hPa for better leaf morphological parameters and optimal root development of tomato transplants in a coarse substrate. Measurements of free proline in plants grown under these irrigation levels support these results. Critical water tension for irrigation pulses and content of free proline in tomato transplants were closely correlated (r(2)=0.95).

description: In mixed music, interactivity and liveness have been buzzwords for the last 50 years. This article proposes the community to discuss more the aesthetic influences of interactivity instead of focusing on the technological aspect. By discussing compositions in a more holistic manner, this author believes that we can gain a better understanding of the affordances of interaction.

description: We investigate the influence of different host-country knowledge sources on the quality and generality of multinational corporation (MNC) innovation. We suggest that the quality of MNC innovation increases with the geographical distance from local industrial organizations. We also argue that the generality of MNC innovation increases with the distance from local research institutions, but decreases after a certain threshold. We explain these relationships based on the different cognitive and geographical distances separating MNC innovation activities from industrial organizations and research institutions. We test our arguments on a sample of US Patent and Trademark Office (USPTO) patents developed in the United States by foreign semiconductor MNCs.

description: Creating and remembering secure passwords is becoming more important and increasingly difficult. To cope with this development, novel mechanisms utilizing tangible interactions provide new and more engaging ways of user authentication. In this work we implement Rubik’s Cube Auth, a prototype that allows to use a standard 3x3x3 Rubik’s Cube as a working authentication mechanism. We found that the concept of Rubik’s Cube Auth was received positively and discuss possible steps for future research, such as conducting user studies to evaluate our prototype, adding a second authentication factor and possible improvements of our prototype.

description: Cross-regional mergers and acquisitions (M&A) transfer control and diffuse knowledge across space, which facilitates the integration of business systems. We analyse about 40,000 cross-regional acquisitions in Europe completed between 2003 and 2017 and distinguish innovative and non-innovative M&A. Both types of deals cluster into communities constituted by countries or groups of neighbouring countries. However, an increasing proportion of deals connect different communities, especially for innovative M&A. More populous and richer regions host more acquiring and target companies and thus broker communities. Research and development expenditure and skilled human capital are additional factors favouring brokerage of regions by attracting acquirers.
