This article examines the representation of Romani migrants in the context of the 2016 debates to ban begging in Sweden, highlighting the ways in which media and political discourse misrepresented, simplified, or omitted the complexities surrounding this controversial policy. Drawing on Multimodal Critical Discourse Analysis (MCDA) of media reports from two leading Swedish newspapers, this article reveals that media and political discourse often decontextualize the ban by employing three key strategies: (1) generalization and polarization, (2) victimizing the general public, and (3) concealing the historical and global context of marginalization and poverty. By portraying begging as an undignified and harmful practice, media and political discourse deflect attention away from the systemic inequalities and socio-economic conditions that lead to begging. This article argues that this decontextualization serves to legitimize and reinforce the ban on begging, creating a self-perpetuating cycle that obstructs meaningful dialogue and prevents the implementation of more effective and compassionate policy solutions that address the root causes of begging in Sweden.

The history of ancient sports shows us that sports practice was not a secular one but was closely linked to religious faith. Whether we are talking about ancient Greece (Athens, Sparta, etc.), whether we are talking about Latin America or the Far East, the presence of homage and respect towards the gods is seen as something sacred and no one could dispute it. We have researched the religious phenomenon in sports for more than 30 years, and the result is like religion. politics and the arts of war decided the history of the world and civilization. (Barbos, 2015). It is proven by ancient writings, but also by archaeological traces, from ancient temples and stadiums dedicated to gods and legendary heroes, such as Hercules, the most famous demigod of the ancient world, who remained in legends as one of those who achieved the most successful sports. This article summarizes some ancient sports competitions, which were strictly related to the respect for the gods, which was rewarded with sports games, such as the Olympic Games of Greece. Religia, politica si mistica in sportul antic. Istoria sporturilor antice ne arată că practica sportivă nu era una laică, ci era strâns legată de credința religioasă. Fie că vorbim de Grecia antică (Atena, Sparta etc.), fie că vorbim de America Latină sau Orientul Îndepărtat, prezența omagiului și a respectului față de zei este văzută ca ceva sacru și nimeni nu l-ar putea contesta. Este dovedit de scrierile antice, dar și de urmele arheologice, din templele și stadioanele antice dedicate zeilor și eroilor legendari, precum Hercule, cel mai faimos semizeu al lumii antice, care a rămas în legende ca unul dintre cei care au realizat cele mai multe. sporturi de succes. Acest articol rezumă câteva competiții sportive antice, care erau strict legate de respectul față de zei, care era recompensat cu jocuri sportive, precum Jocurile Olimpice din Grecia.

Many analytical methods have been successfully employed for the study of minerals, in particular, vibrational infrared (FTIR) and Raman spectroscopies and X-ray powder diffraction (XRPD). The advantages of the vibrational spectroscopic techniques for identifying and characterizing minerals include: rapid and versatile use; qualitative and quantitative chemical signatures; distinctive chemical fingerprint of a material; indirect determination of the crystal features (polymorphism, isomorphism, coordination, degree of deformation of structural polyhedra); small sample quantity (area less than 1 μm2 for Raman); wide coverage of 4,000 – 50 cm−1 region in a single scan; in situ and direct measurements without sample preparation; nondestructive use; etc. On the other hand, XRPD is a destructive technique that, depending on the method used and the density of the material, requires from a few micrograms up to around 5 grams of sample quantity for analysis. In spite of that, it is a rapid and powerful technique used in mineral studies with relatively straightforward interpretation of the results. During the last decade, portable X-ray powder diffractometers for the nondestructive analysis of art and archeological materials have been developed along with the portable and hand-held vibrational spectroscopy instrument. Here, some advantages and limitations in the process of the complementary use of FTIR and Raman vibrational spectroscopy and XRPD for identification and characterization of minerals are outlined.

Gestational trophoblastic neoplasia (GTN) is extremely rare, but has a very good prognosis, with a cure rate close to 100%, for low-risk diseases. This article describes the case of a healthy 28-year-old nulliparous patient with GTN resistant to multiple lines of treatment. The era of immunotherapy is revolutionizing oncology, having already proved its worth in the treatment of many cancers. This article will have a specific focus on the emerging role of immunotherapy in the treatment of GTN. Unfortunately, the use of an immune checkpoint inhibitor (ICI) failed in our case, emphasizing on the necessity to clearly define the future role of immune therapy in GTN. Finally, given the rapid progression of the disease after hysterectomy, induction with Paclitaxel- Ifosfamide and then intensification with high-dose Carboplatin and Etoposide with peripheral blood stem cell support was given as a rescue therapy with still curative intent.

The study aimed to identify and explain the typical differences in low-intensity high-volume resistance training (LIHV-RT) performances for major muscle groups between rural versus urban young female students to establish the relevant set of quantitative and qualitative resistance training parameters. The study sample included 46 recreational active female students at the Transilvania University of Brașov, (mean ± SD age, 20 ± 1 year; body mass, 60 ± 3 kg; height, 160 ± 4 cm) grouped urban vs. rural. The study used modified resistance exercise machines for the hamstring- and quadricep-group muscles, equipped with a dynamometer and sensors for identifying developed forces and accelerations. A number of 368 tests were performed, representing two attempts for each subject, for knee flexion and knee extension exercises, with two different loads. For the performance analysis some variables were considered: the maximum number of repetition until failure, maximum force developed, maximum acceleration, the duration of the set and the mean time per repetition. The maximum number of repetition to failure shows a significant higher value for rural than urban in case of knee flexion (d = 0.98 [0.32, 1.54] for load 1(L1) and d = 0.65 [0.03, 1.21] for load 2(L2)) and in case of knee extension (d = 1.89 [1.11, 2.48] for L1 and d = 1.67 [0.92, 2.25] for L2). The total duration of the sets shows a significant higher value for rural than urban in case of knee flexion (d = 0.84 [0.19, 1.39] for L2) and in case of knee extension (d = 1.46 [0.74, 2.03] for L1 and d = 1.56 [0.98, 2.14] for L2). Additionally we found differences in the quality of the relevant repetitions execution and in the impulse developed during the LIHV- MNRF sets. The study’s main finding was that there are differences in LIHV-RT performances knee flexion and knee extension antagonistic exercises, between rural and urban female students. We concluded that the obtained results allow teachers to understand the optimal design of RT programs for the different groups of participants, in order to adapt their teaching techniques so that their final objectives are achieved, insisting on particular aspects of the theoretical or practical contents.

Building an investment portfolio is a problem that numerous researchers have addressed for many years. The key goal has always been to balance risk and reward by optimally allocating assets such as stocks, bonds, and cash. In general, the portfolio management process is based on three steps: planning, execution, and feedback, each of which has its objectives and methods to be employed. Starting from Markowitz's mean-variance portfolio theory, different frameworks have been widely accepted, which considerably renewed how asset allocation is being solved. Recent advances in artificial intelligence provide methodological and technological capabilities to solve highly complex problems, and investment portfolio is no exception. For this reason, the paper reviews the current state-of-the-art approaches by answering the core question of how artificial intelligence is transforming portfolio management steps. Moreover, as the use of artificial intelligence in finance is challenged by transparency, fairness and explainability requirements, the case study of post-hoc explanations for asset allocation is demonstrated. Finally, we discuss recent regulatory developments in the European investment business and highlight specific aspects of this business where explainable artificial intelligence could advance transparency of the investment process.

Key Clinical Message This research investigates the trueness and precision of 3D printing technology in dental applications, specifically focusing on dimensional variations observed in models printed at different angles. The methodology involved importing a dental model into slicing software, adjusting its orientation, and implementing support structures for stability. Subsequently, the model underwent 3D printing five times for each orientation using appropriate equipment and underwent post‐processing steps, including cleaning, washing, and UV‐light post‐curing. The printed models were then scanned using a specialized desktop scanner for further analysis. Accuracy assessment was carried out using dedicated software, employing an algorithm for precise alignment by comparing the scanned files. Color deviation maps were utilized to visually represent variations, aiming to evaluate how positioning during printing influences the trueness and precision of 3D‐printed dental models. Trueness and precision analyses involved the Shapiro–Wilk test for normality and a one‐way ANOVA to compare means of three independent groups, with statistical analyses conducted using IBM SPSS Statistics software. The color maps derived from 3D comparisons revealed positive and negative deviations, represented by distinct colors. Comparative results indicated that models positioned at 0° exhibited the least dimensional deviation, whereas those at 90° showed the highest. Regarding precision, models printed at 0° demonstrated the highest reproducibility, while those at 15° exhibited the lowest. Based on the desired level of precision, it is recommended that printed models be produced at an inclination angle of 0°.

Physics - Instrumentation and Detectors ,High Energy Physics - Experiment - Abstract
After the Phase-2 high-luminosity upgrade to the Large Hadron Collider (LHC), the collision rate and therefore the background rate will significantly increase, particularly in the high $\eta$ region. To improve both the tracking and triggering of muons, the Compact Muon Solenoid (CMS) Collaboration plans to install triple-layer Gas Electron Multiplier (GEM) detectors in the CMS muon endcaps. Demonstrator GEM detectors were installed in CMS during 2017 to gain operational experience and perform a preliminary investigation of detector performance. We present the results of triple-GEM detector performance studies performed in situ during normal CMS and LHC operations in 2018. The distribution of cluster size and the efficiency to reconstruct high $p_T$ muons in proton--proton collisions are presented as well as the measurement of the environmental background rate to produce hits in the GEM detector., Comment: 10 pages, 5 figures

Physics - Instrumentation and Detectors ,High Energy Physics - Experiment - Abstract
An estimate of environmental background hit rate on triple-GEM chambers is performed using Monte Carlo (MC) simulation and compared to data taken by test chambers installed in the CMS experiment (GE1/1) during Run-2 at the Large Hadron Collider (LHC). The hit rate is measured using data collected with proton-proton collisions at 13 TeV and a luminosity of 1.5$\times10^{34}$ cm$^{-2}$ s$^{-1}$. The simulation framework uses a combination of the FLUKA and Geant4 packages to obtain the hit rate. FLUKA provides the radiation environment around the GE1/1 chambers, which is comprised of the particle flux with momentum direction and energy spectra ranging from $10^{-11}$ to $10^{4}$ MeV for neutrons, $10^{-3}$ to $10^{4}$ MeV for $\gamma$'s, $10^{-2}$ to $10^{4}$ MeV for $e^{\pm}$, and $10^{-1}$ to $10^{4}$ MeV for charged hadrons. Geant4 provides an estimate of detector response (sensitivity) based on an accurate description of detector geometry, material composition and interaction of particles with the various detector layers. The MC simulated hit rate is estimated as a function of the perpendicular distance from the beam line and agrees with data within the assigned uncertainties of 10-14.5%. This simulation framework can be used to obtain a reliable estimate of background rates expected at the High Luminosity LHC., Comment: 16 pages, 9 figures, 6 tables

Quantitative Biology - Molecular Networks - Abstract
To better understand the potential of drug repurposing in COVID-19, we analyzed control strategies over essential host factors for SARS-CoV-2 infection. We constructed comprehensive directed protein-protein interaction networks integrating the top ranked host factors, drug target proteins, and directed protein-protein interaction data. We analyzed the networks to identify drug targets and combinations thereof that offer efficient control over the host factors. We validated our findings against clinical studies data and bioinformatics studies. Our method offers a new insight into the molecular details of the disease and into potentially new therapy targets for it. Our approach for drug repurposing is significant beyond COVID-19 and may be applied also to other diseases., Comment: 21 pages, 3 tables, 9 figures, supplementary information included at the end, 4 files as supplementary material

The camel milk sector is still little explored and especially the effect of the camel breeding system on certain properties and chemical compositions of camel milk. This study aims to assess the potential impact of the transition in the camel breeding system on milk productivity and the physicochemical composition of camel milk. To achieve this objective, a preliminary survey was conducted involving several breeders actively practicing the two targeted breeding systems (extensive and semi-intensive) in Algeria. This survey revealed milk production levels of 2 L/d and 3.5 L/d for the extensive and semi-intensive systems, respectively. Physicochemical analyses of these two types of camel milk (from extensive and semi-intensive breeding) were carried out. Various parameters were measured, including pH, acidity, density, total solids, solids-not-fat, ash levels, lactose, calcium, vitamin C, total proteins, whey proteins, and caseins. The results of these analyses indicate that the transition from extensive breeding system to the semi-intensive system significantly impacts the physicochemical quality of camel milk. Specifically, camel milk from the semi-intensive breeding system becomes less dense, more acidic and less rich in total dry matter particularly in solids-not-fat, which includes lactose, vitamin C, and minerals and notably calcium. Furthermore, this milk has become richer in proteins both total proteins and whey proteins, and more notably in caseins.

According to the literature, Romania maintains a close trade relationship, in terms of agri-food products, with Germany, especially the import-export relationship, thus, Romania imports either in terms of value the most, or in terms of assortment diversification, most from Germany. Thus, in this paper, the aim is to carry out an analysis of all the chapters of the Combined Nomenclature, related to the agri-food sector to determine the key chapters in terms of demand in Romania, using the ABC method which can structure the range of products in three categories of importance.

adiocarbon dating ,ams ,charcoal ,carbonised wood ,forested archaeological sites ,Archaeology ,CC1-960 - Abstract
Radiocarbon dating by AMS accelerated ion mass spectrometry method, used from 2012 at IFIN-HH-Măgurele, offered recently the scientific frame for an interdisciplinary approach, from archaeologic and archaeometric perspectives, applied to wood samples. The first AMS results, issued in 2021 on six samples from Măguricea Branului archaeological site, have suggested a chronology around the 13th century AD, the differences being explained on terms detailed in this paper. The latter four samples, collected in the next archaeological campaign, gave very different dates. The difficulties experienced with these four samples driven us to develop new lab treatment, aiming carbonization of wood. Even so, the samples from 2022 could not be dated in a helpful manner, with parameters as terminus post quem, time-width, apparent ages. The paper could be of interest to archaeologists taking wood samples for AMS dating.

The paper presents six samples originating from archaeologically investigated contexts in the Early Iron Age site of Saharna–Țiglău. Three samples were collected, after anthropological analysis, from funerary features excavated in 2022, and the remaining samples were taken from pits within the settlement. Calibration of the six AMS radiocarbon data places the chronological sequence with a 95.4% probability in the range calBC 1284-797. From the association of the data, it is almost obvious to conclude that one of the earliest known dates for an Early Iron Age context with stamped pottery in the Carpathian-Balkan area has been recorded at Saharna–Țiglău.

This paper introduces a novel power supply voltage adjustment strategy that can determine the optimum voltage value based on the amount of absorbed power. The novel automatic voltage adjustment technique was called inverse maximum power point tracking (iMPPT). The proposed control strategy consists of a modified maximum power point tracking (MPPT) algorithm (more precisely the P&O method). In this case, the modified MPPT technique establishes the minimum value of the input absorbed power of a consumer load served by a switched-mode power supply (SMPS). The iMPPT adjusts the input power by modifying the input voltage of the main power supply. The served loads are connected to the variable power supply via an interfacing power electronics converter that performs the automatic voltage regulation function (AVR). The optimal value of the input voltage level can be achieved when the input power of the automatic voltage regulation converter is at a minimum. In that case, the energy conversion efficiency ratio is at a maximum, and the overall losses related to the front-end power stage are at a minimum. The proposed technique can also be considered a Maximum Efficiency Tracking (MET) method. By performing the inverse operation of a maximum power point tracking algorithm on the input demanded power of a switched mode power supply (SMPS), the optimum input voltage level can be determined when the maximum energy conversion ratio (related to a given load level) is achieved. The novel proposed iMPPT method can improve the energy conversion ratio from 85% up to approximately 10% in the case of an output power level of 800 W served by a synchronous buck converter at the input voltage level of 350 V. The total amount of recovered power in this situation can be approximately 100 W.

Renal cell carcinoma is the most common type of primary urogenital cancer, usually resistant to radiotherapy and chemotherapy. Hypertrophic lichen planus is an inflammatory dermatosis characterized by the presence of papulosquamous and intensely pruritic lesions. The association of these two conditions is unusual, being reported in the specialized literature only in a few rare cases with the onset of lichenoid lesions after patients have undergone various forms of treatment. The case of a 62-year-old male patient who was admitted for severe abdominal pain due to a giant renal tumor associated with a hypertrophic plaque located on the anterior part of the left calf is presented. After (clinical, biochemical, imaging) diagnosis, surgery was performed for en bloc removal of the entire mass, adrenal gland, and spleen. The histopathological exam established the diagnosis of a moderately differentiated T2b clear cell Grawitz tumor, without regional lymph node metastasis (stage II). The patient continued local corticosteroid therapy in the hospital for hypertrophic lichen planus lesions, being referred to the oncology department after discharge.

Background. Physiological changes that occur during pregnancy make maternal sepsis a difficult condition to diagnose and treat, still having a fairly high mortality rate. Consequently, an early diagnosis and prompt therapeutic management of sepsis can significantly decrease mortality. The purpose of this study is to review literature data that present current practices in the management of obstetric sepsis. Methods. To collect the data required for the study, we performed a search of published articles in the PubMed and Google Scholar databases related to obstetric sepsis. Research paper articles from the period 2012-2022 were included in the analysis. In addition, 145 articles from the period 2012-2022 were evaluated, with the aim of finding out in which situations the risk of maternal death is higher. Thus, the analysis included a total number of 151 articles, which were divided into two distinct stages. Results. The risk of maternal death is higher among patients with the human immunodeficiency virus (HIV), followed by Escherichia coli, genital tract infection, cancer, drug users and in the case of patients with chronic liver disease. Conclusions. After analyzing the data, we found that prompt and focused antibiotic therapy as well as fluid resuscitation are essential to increase the chances of survival of these patients.

The aim of this study is to explain from an econometric point of view, the relationship between digitalisation in the public domain and opportunities in the environment of public sector organisations. The analysis is carried out on a set of 29 European countries, and the EU-27 average, on a specific period of time. The panel data regression analysis reveals both positive and negative relationships, as well as direct and indirect connections between variables of interest. After presenting the regression results, one can conclude that changes in the level of opportunities may influence changes in the digitisation process at the level of each country included in the analysis. Six hypotheses were tested by the econometric model. Among them, only one has been validated for 26 out of 30 cases. It is the one testing the positive link between digitisation in the public sector and the way the Internet is being used, respectively, for goods and services search activities.

In this research paper, we examined the influence of demographic and household factors on adecision to surrender a life insurance policy before the end of the policy term. As per thehandbook on Indian Insurance Statistics 2020-21, by the 5 th year of policy sale, only 4 out of 24 life insurers could retain half of their policies. One of the reasons for this low persistenceis the increased surrender of policies. Surrendering a policy means the policyholdercancelling the policy and agreeing to take the cash value/surrender value accrued to thepolicy over time and forgoing the death benefit or maturity benefit. Generally, a policyacquires surrender value after the policyholder has paid the premiums continuously for threeyears. A survey of randomly selected 537 policyholders was conducted using a structuredquestionnaire to examine the influence of demographic and household factors on a decisionto surrender a life insurance policy. Results of our study suggest that demographic andhousehold factors influence the decision to surrender a life insurance policy. Marital statusand occupation are statistically significant predictors of the decision to surrender a policy.

In advanced economies there is a tendency to move to digitization and cashless financialeconomic activities. In this sense, the number of cryptocurrencies that contributed more to this trend increased. In this article the authors aim to highlight the functions of money in the modern economy taking into account these trends and developments. In this sense, Bitcoin and other digital currencies can cause a change in the functions of money. In the article we sought to demonstrate the extent to which digital currencies can be considered money, using a complex methodology, logical and interpretive analyses, starting from the comparative study of the situation of coins and the existing situation in the monetary mass of the money that exists in circulation.

In this paper we tried to outline the definitional framework of FDI, starting from the definition and way of achieving FDI, until the presentation of some concise notions from the specialized literature with the aim of establishing what are the determinants of FDI and what are the positive and negative effects on which they generate in the host economies. We paid attention to the game framework in which FDI manifests itself and carried out a critical analysis on the attractiveness of the legislative framework in Romania for foreign investors. The analysis goes beyond national borders and extends to Bulgaria, the Czech Republic, Poland and Hungary, as we consider that the states in the region, members of the EU and with a similar transition history, represent formidable rivals for Romania in the race to attract FDI.

Strontium ferromolybdate, Sr2FeMoO6, is an important member of the family of double perovskites with the possible technological applications in the field of spintronics and solid oxide fuel cells. Its preparation via a multi-step ceramic route or various wet chemistry-based routes is notoriously difficult. The present work demonstrates that Sr2FeMoO6 can be mechanosynthesized at ambient temperature in air directly from its precursors (SrO, α-Fe, MoO3) in the form of nanostructured powders, without the need for solvents and/or calcination under controlled oxygen fugacity. The mechanically induced evolution of the Sr2FeMoO6 phase and the far-from-equilibrium structural state of the reaction product are systematically monitored with XRD and a variety of spectroscopic techniques including Raman spectroscopy, 57Fe Mössbauer spectroscopy, and X-ray photoelectron spectroscopy. The unique extensive oxidation of iron species (Fe0 → Fe3+) with simultaneous reduction of Mo cations (Mo6+ → Mo5+), occuring during the mechanosynthesis of Sr2FeMoO6, is attributed to the mechanically triggered formation of tiny metallic iron nanoparticles in superparamagnetic state with a large reaction surface and a high oxidation affinity, whose steady presence in the reaction mixture of the milled educts initiates/promotes the swift redox reaction. High-resolution transmission electron microscopy observations reveal that the mechanosynthesized Sr2FeMoO6, even after its moderate thermal treatment at 923 K for 30 min in air, exhibits the nanostructured nature with the average particle size of 21(4) nm. At the short-range scale, the nanostructure of the as-prepared Sr2FeMoO6 is characterized by both, the strongly distorted geometry of the constituent FeO6 octahedra and the extraordinarily high degree of anti-site disorder. The degree of anti-site disorder ASD = 0.5, derived independently from the present experimental XRD, Mössbauer, and SQUID magnetization data, corresponds to the completely random distribution of Fe3+ and Mo5+ cations over the sites of octahedral coordination provided by the double perovskite structure. Moreover, the fully anti-site disordered Sr2FeMoO6 nanoparticles exhibit superparamagnetism with the blocking temperature T B = 240 K and the deteriorated effective magnetic moment μ = 0.055 μ B per formula unit.

We consider the problem of learning from training data obtained in different contexts, where the underlying context distribution is unknown and is estimated empirically. We develop a robust method that takes into account the uncertainty of the context distribution. Unlike the conventional and overly conservative minimax approach, we focus on excess risks and construct distribution sets with statistical coverage to achieve an appropriate trade-off between performance and robustness. The proposed method is computationally scalable and shown to interpolate between empirical risk minimization and minimax regret objectives. Using both real and synthetic data, we demonstrate its ability to provide robustness in worst-case scenarios without harming performance in the nominal scenario., Comment: Paper under SPL review

Astrophysics - High Energy Astrophysical Phenomena - Abstract
The supernova remnant (SNR) 3C 397 is thought to originate from a Type Ia supernova (SN Ia) explosion of a near-Chandrasekhar-mass ($M_{\rm Ch}$) progenitor, based on the enhanced abundances of Mn and Ni revealed by previous X-ray study with Suzaku. Here we report follow-up XMM-Newton observations of this SNR, conducted with the aim of investigating the detailed spatial distribution of the Fe-peak elements. We have discovered an ejecta clump with extremely high abundances of Ti and Cr, in addition to Mn, Fe, and Ni, in the southern part of the SNR. The Fe mass of this ejecta clump is estimated to be $\sim$ 0.06 $M_{\odot}$, under the assumption of a typical Fe yield for SNe Ia (i.e., $\sim$ 0.8 $M_{\odot}$). The observed mass ratios among the Fe-peak elements and Ti require substantial neutronization that is achieved only in the innermost regions of a near-$M_{\rm Ch}$ SN Ia with a central density of $\rho_c \sim 5 \times 10^9$ g cm$^{-3}$, significantly higher than typically assumed for standard near-$M_{\rm Ch}$ SNe Ia ($\rho_c \sim 2 \times 10^9$ g cm$^{-3}$). The overproduction of the neutron-rich isotopes (e.g., $^{50}$Ti and $^{54}$Cr) is significant in such high-$\rho_c$ SNe Ia, with respect to the solar composition. Therefore, if 3C 397 is a typical high-$\rho_c$ near-$M_{\rm Ch}$ SN Ia remnant, the solar abundances of these isotopes could be reproduced by the mixture of the high- and low-$\rho_c$ near-$M_{\rm Ch}$ and sub-$M_{\rm Ch}$ Type Ia events, with $\lesssim$ 20 % being high-$\rho_c$ near-$M_{\rm Ch}$., Comment: Accepted by ApJL; 9 pages with 4 figures and 1 table

We discuss in this survey several network modeling methods and their applicability to precision medicine. We review several network centrality methods (degree centrality, closeness centrality, eccentricity centrality, betweenness centrality, and eigenvector-based prestige) and two systems controllability methods (minimum dominating sets and network structural controllability). We demonstrate their applicability to precision medicine on three multiple myeloma patient disease networks. Each network consists of protein-protein interactions built around a specific patient's mutated genes, around the targets of the drugs used in the standard of care in multiple myeloma, and around multiple myeloma-specific essential genes. For each network we demonstrate how the network methods we discuss can be used to identify personalized, targeted drug combinations uniquely suited to that patient., Comment: 55 pages, 3 figures

Electrical Engineering and Systems Science - Signal Processing - Abstract
We consider the problem of range-Doppler imaging using one-bit automotive LFMCW1 or PMCW radar that utilizes one-bit ADC sampling with time-varying thresholds at the receiver. The one-bit sampling technique can significantly reduce the cost as well as the power consumption of automotive radar systems. We formulate the one-bit LFMCW/PMCW radar rangeDoppler imaging problem as one-bit sparse parameter estimation. The recently proposed hyperparameter-free (and hence user friendly) weighted SPICE algorithms, including SPICE, LIKES, SLIM and IAA, achieve excellent parameter estimation performance for data sampled with high precision. However, these algorithms cannot be used directly for one-bit data. In this paper we first present a regularized minimization algorithm, referred to as 1bSLIM, for accurate range-Doppler imaging using onebit radar systems. Then, we describe how to extend the SPICE, LIKES and IAA algorithms to the one-bit data case, and refer to these extensions as 1bSPICE, 1bLIKES and 1bIAA. These onebit hyperparameter-free algorithms are unified within the one-bit weighted SPICE framework. Moreover, efficient implementations of the aforementioned algorithms are investigated that rely heavily on the use of FFTs. Finally, both simulated and experimental examples are provided to demonstrate the effectiveness of the proposed algorithms for range-Doppler imaging using one-bit automotive radar systems.
