title: The mobility of scientists and inventors: patterns and determinants
Creators: name: Verginer, Luca
Publisher: name: IMT Alti Studi Lucca
Year: 2019

description: Life Scientists working both at Universities and private institutions are very mobile. This fact is reflected both in their
 tendency to move globally, from city to city, as well as from
 institution to institution. This thesis addresses several questions regarding the mobility patterns of these scientists and
 tests possible determinants for their relocation choice.
 We develop a novel dataset tracking the mobility of 3.7 million scientists across 9,745 cities over two decades. We show
 that mobility is marked by national borders and shared languages and that the mobility network is dominated by a small
 set of “global cities”. We also find that only a few countries clearly benefit from international exchange. Moreover,
 we find that young and prolific researchers gravitate towards
 these “global cities”.
 We use the mobility data to show how state and federal Stem
 Cell funding restrictions in the US have affected the spatial
 distribution of scientists as well as their propensity to leave
 the country. In fact we find that differential state and federal
 approaches to Stem Cell research has had the overall effect of
 geographically concentrating scientists and averting an exodus of these researchers.
 Finally, we analyze the impact of M&As in the Pharmaceutical Sector to establish if these shocks cause a higher than average turnover. High turnover of R&D personnel in this R&D
 intensive sector is an undesirable outcome. We do in fact find
 that turnover is higher following an acquisition. However,
 as noted elsewhere, acquired companies experience often financial distress before the event and so defection starts even
 before the deal takes place.

description: The detection and parameter estimation of moving targets is one of the most important tasks in radar. Arrays of randomly distributed antennas have been popular for this purpose for about half a century. Yet, surprisingly little rigorous mathematical theory exists for random arrays that addresses fundamental question such as how many targets can be recovered, at what resolution, at which noise level, and with which algorithm. In a different line of research in radar, mathematicians and engineers have invested significant effort into the design of radar transmission waveforms which satisfy various desirable properties. In this paper we bring these two seemingly unrelated areas together. Using tools from compressive sensing we derive a theoretical framework for the recovery of targets in the azimuth-range-Doppler domain via random antennas arrays. In one manifestation of our theory we use Kerdock codes as transmission waveforms and exploit some of their peculiar properties in our analysis. Our paper provides two main contributions: (i) We derive the first rigorous mathematical theory for the detection of moving targets using random sensor arrays. (ii) The transmitted waveforms satisfy a variety of properties that are very desirable and important from a practical viewpoint. Thus our approach does not just lead to useful theoretical insights, but is also of practical importance. Various extensions of our results are derived and numerical simulations confirming our theory are presented.

description: The FAIR principles require research data to be published with complete metadata and ideally shared at different key milestones during the research. However, currently this requires creation of dataset records and uploading of large data files to data repositories manually, which is time consuming. In this workshop, we will present and demonstrate open-source faily Python package and JupiterFAIR JupyterLab extension we developed, which allow to easily create and quickly publish research datasets to popular research data repositories, such as Zenodo, figshare, and 4TU.ResearchData. At the end of the workshop the participants will be able to perform these tasks with ease.

description: We study the effects of radiative transfer on the Probability Distribution Functions (PDFs) of simulations of magnetohydrodynamic turbulence in the widely studied $^{13}$CO 2-1 transition. We find that the integrated intensity maps generally follow a log-normal distribution, with the cases that have $τ\approx 1$ best matching the PDF of the column density. We fit a 2D variance-sonic Mach number relationship to our logarithmic PDFs of the form $σ_{ln(Σ/Σ_0)}^2=A\times ln(1+b^2{\cal M}_s^2)$ and find that, for parameter $b=1/3$, parameter $A$ depends on the radiative transfer environment. We also explore the variance, skewness, and kurtosis of the linear PDFs finding that higher moments reflect both higher sonic Mach number and lower optical depth. Finally, we apply the Tsallis incremental PDF function and find that the fit parameters depend on both Mach numbers, but also are sensitive to the radiative transfer parameter space, with the $τ\approx 1$ case best fitting the incremental PDF of the true column density. We conclude that, for PDFs of low optical depth cases, part of the gas is always sub-thermally excited so that the spread of the line intensities exceeds the spread of the underlying column densities and hence the PDFs do not reflect the true column density. Similarly, PDFs of optically thick cases are dominated by the velocity dispersion and therefore do not represent the true column density PDF. Thus, in the case of molecules like carbon monoxide, the dynamic range of intensities, structures observed and consequently, the observable PDFs, are less determined by turbulence and more-often determined by radiative transfer effects.

On the carbonaceous carriers of IR plateau and continuum emission

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: This study explores the molecular origins of plateaus and continuum underlying IR and FIR bands emitted by compact nebulae, especially proto-planetary nebulae. Computational organic chemistry codes are used to deliver the vibrational integrated band intensities of various large, typical carbonaceous structures. These spectra are composed of a rather continuous distribution of weak modes from which emerge the fingerprints. The 6 to 18-mu region is interspersed with a great many weak lines, to which the plateaus are assigned. Similarly, the far IR spectrum is ascribed to the phonon (skeletal) spectrum which is readily identified beyond 18 mu. The absorptivities and absorption cross-sections per interstellar H atom deduced from these spectra are comparable with those of laboratory dust analogs and astronomical measurements, respectively. Moreover, the 5-35 mu spectra of two typical Proto-Planetary Nebula were reasonably well simulated with combinations of molecules containing functional groups which carry the 21- and 30-mu bands, and molecules devoid of these but carrying strong phonon spectra. These results may help understand the emergence of plateaus, the origin of continua underlying FIR bands, as well as the composition of circumstellar dust.

description: Conservation and sustainable use of biodiversity, ecosystems and their services are key principles behind the establishment of “Biosphere Reserves”. Mapping of ecosystem services is one of the activities that is expected to increase the knowledge of sustainable land use planning. The Biosphere Reserves, established by the UNESCO Man and Biosphere Programme, aims to find the balance between nature conservation, use of natural resources, recreation and other culture-related activities. For this purpose, the ecosystem services approach is a promising tool for examining the relationships between people and nature in practice. This study applies the ecosystem services approach and examines which ecosystem services are perceived to be relevant in the North Karelia Biosphere Reserve in Eastern Finland. The results of a matrix method, with expert-based approach, showed that particularly old-growth forests and undrained open and forested mires have a broader potential to provide different ecosystem services. Water and urban areas are considered important for cultural services. However, these areas cover only a relatively small area altogether. The results of the ecosystem services assessment were compared to areas of high biodiversity, as defined by local biodiversity experts. The areas with high capacity for ecosystem services provision (from now on “high ecosystem services areas”) were found in areas with high biodiversity. In most cases, these areas are already under protection. The results also showed that ambiguity is an issue with the use of the ecosystem services concept in both stakeholder and expert evaluations.

description: Exact non-perturbative partition functions of coupling constants and external fields exhibit huge hidden symmetry, reflecting the possibility to change integration variables in the functional integral. In many cases this implies also some non-linear relations between correlation functions, typical for the tau-functions of integrable systems. To a variety of old examples, from matrix models to Seiberg-Witten theory and AdS/CFT correspondence, now adds the Chern-Simons theory of knot invariants. Some knot polynomials are already shown to combine into tau-functions, the search for entire set of relations is still in progress. It is already known, that generic knot polynomials fit into the set of Hurwitz partition functions -- and this provides one more stimulus for studying this increasingly important class of deformations of the ordinary KP/Toda tau-functions.

description: In Belgium no publicly available information exists on the spread, quality, results nor follow-up of antireflux and hiatal hernia surgery, in contrast to the recently centralized esophageal cancer surgery. The aim of this study was to create a snap shot of the current practice in Belgium. An online questionnaire was distributed among all members of the Royal Belgian Society for Surgery in autumn 2021. A total of 33 questions spread over four sections were asked, covering demographics, current practice (case load, case mix, indications, preoperative workup, patient information, average length of stay, follow up, quality of life (QOL)), operative techniques and future thoughts. Twenty-four surgeons completed the questionnaire. Surgical indications are discussed multidisciplinary and based on guidelines in 67%. Workup includes endoscopy, pH-monitoring and manometry in 100%. Barium swallow, impedance and gastric emptying tests were added in respectively 83%, 42% and 13%. Symptom or QOL scores were used in 17%. 81% are performed as primary surgery, 18% redo surgery and 1% resections. Laparoscopic procedures are reported in 99%: Nissen(-Rosetti) 79%, Toupet/Lind 15%, partial gastrectomy 5% and Collis gastroplasty 1%. Discharge is planned on POD1 in 42% and on POD2 in 54%. 50% performs follow-up <1 year. Interest in further clinical research collaboration was expressed in 92%. Antireflux and hiatal hernia surgery is not standardized in Belgium. There is an evident variety in clinical practice, but this questionnaire shows similarity amongst respondents regarding workup and surgical approach. There is a willingness for future research collaborations.

Aus PPS-Entscheidungen können daher neben den Auswirkungen auf die direkt adressierten Arbeitssysteme auch unerwartete Wechselwirkungseffekte bezogen auf den gesamten Produktionsbereich resultieren. Diese wirken sich auf die logistische Leistungsfähigkeit aus und sollten folglich bei der Gestaltung und Konfiguration der PPS berücksichtigt werden.
description: In production areas organized in accordance to the workshop principle, there are usually complex material flow relationships between the individual work systems. PPC decisions can therefore result not only in effects on directly addressed work systems but also in unexpected interaction effects on the entire production area.

description: We propose the following model for speciation and extinction. Birth and deaths occur according to spatially inhomogeneous contact rates. We assume that the ratio of the birth rate over the death rate at a site converges to some limit as the site goes to infinity. We show that the existence of a phase transition depends critically on the value of this limit.

Обследовано 182 жителя Ханты-Мансийского автономного округа мужского пола. Основная группа – 94 водителя: 36 со стажем работы менее 5 лет и 56 – более 5 лет. Контрольная группа – 88 служащих. Средний возраст – 32,6±6,2 лет. Стандартными методами в эритроцитах и плазме крови определяли восстановленный глутатион (GSH), окисленную форму глутатиона (GSSG), активность глутатионпероксидазы (ГПO), глутатион-S-трансферазу (ГST), глутатионредуктазу (ГР). У лиц со стажем менее 5 лет, подвергающихся токсическому воздействию вредных химических веществ, выявлены ранние значимые изменения метаболического статуса, а именно: системы глутатиона, характеризующейся снижением содержания восстановленного глутатиона (в 1,4 раза), снижением уровня GSТ активности (на 72% и 64% соответственно в эритроцитах и плазме крови) при увеличении активности GR (на 50%). Более выраженные изменения адаптивных метаболических реакций в организме работников автотранспортных предприятий, имеющих трудовой стаж более 5 лет, связаны с дестабилизацией системы глутатиона с признаками снижения активности всех его антиоксидантных ферментов.

description: Причинно-следственная связь сахарного диабета (СД) 2-го типа и неалкогольной жировой болезни печени (НАЖБП) является предметом многочисленных дискуссий. Связующим патогенетическим звеном одного и другого заболевания является: инсулинорезистентность, нарушения липидного обмена и хроническое субклинически протекающее воспаление, на уровне гепатоцита. Распространенность НАЖБП возрастает так же стремительно, как и СД 2-го типа.
В развитии НАЖБП важную роль играют провоспалительные цитокины – интерлейкины-6 и -8 и фактор некроза опухоли «а» (ФНО-а). Последний является многофункциональным провоспалительным цитокином, секретирующимся, в основном, макрофагами преимущественно жировой ткани и обладающим ауто- и паракринными эффектами. Неалкогольная жировая болезнь печени у больных с СД 2-го типа всегда сочетается с атерогенной дислипидемией и, прежде всего, с гипертриглицедемией.
В прогрессировании НАЖБП и развитии фиброза печени участвуют различные факторы роста, стимулирующие хрони-ческое воспаление и фиброгенез путем усиления образования коллагена и соединительной ткани в печени: транс-формирующий фактор роста-в (TGF-в), инсулиноподобный фактор роста 1 (IGF-1), тромбоцитарный фактор роста (PDGF).
Интенсивно изучаются молекулярно-клеточные механизмы развития НАЖБП с участием печеночного фарнезоидного Х-рецептора (FXR). Выявлен маркер прогрессирующего и осложненного течения НАЖБП и СД 2-го типа – ретинол связывающий протеин-4.
Сахарный диабет 2-го типа и НАЖБП – метаболический тандем аккордно развивающихся событий – имеют однотипные патогенетические корни. Метаболические эффекты этого тандема являются причиной развития тяжелого течения сердечно-сосудистых заболеваний (ССЗ) и их осложнений и заболеваний желчного пузыря.
Новым высокоэффективным методом лечения и профилактики СД 2-го типа, НАЖБП И ССЗ может являться применение моноклональных антител – ингибиторов пропротеин ковертазы субтилин/кексина типа-9 (PCSK9) – регуляторов экспрессии рецепторов липопротеинов низкой плотности.

description: Man Made Noise (MMN) und dessen Abstrahlung über das elektrische Energieversorgungsnetz, Informationsnetzwerke (VDSL, Kabelfernsehen) ist eine vermeidbare Störung der primär an Funkdienste zugewiesenen Frequenzbereiche bis 30 MHz [1]. Es besteht die Sorge, dass die Überlagerung weiterer Anwendungen in vielen Haushalten den MMN-Pegel weiter ansteigen lässt [2]. Zu den schon in den 1960-ziger Jahren bekannten Störquellen sind deutlich mehr leistungselektronische Anwendungen mit anderem Störpotenzial hinzugekommen [3]. Der vorliegende Beitrag berichtet über das Electromagnetic Noise Area Monitoring System (ENAMS). Dies beinhaltet Konzept und Realisierung für ein langfristiges Monitoring elektromagnetischer Störungen im Frequenzbereich zwischen 50 kHz und 30 MHz [4]. Seit mehr als einem Jahr sind eine größere Anzahl von Anlagen über die Bundesrepublik Deutschland verteilt aufgestellt und werden aktuell betrieben. Durch Anwendung der ITU Regulations [5] und ein daran angelehntes Messverfahren mit reproduzierbarem Wandlungsfaktor der als Feldsensoren verwendeten kurzen Antennen wird der gesamte Frequenzbereich mehrfach in der Stunde erfasst und die Messdaten in einem Server gesammelt. Die inzwischen mehr als 50 Messstandorte sind auf drei ITU-R P.372-Kategorien, Bild 1, (City/Industrial, Residential, Rural) verteilt und sollen für die kommenden Jahre dort dauerhaft in Betrieb bleiben. Diese oberen 3 Kategorien sind an Orten zu erwarten, an denen u.a. auch Amateurfunkdienst betrieben wird. Das Bild 1 zeigt im doppelt logarithmischen Maßstab den Verlauf der mittleren Rauschzahl F in dB über der Frequenz, wie er durch die Summe aller Störungen in den 1960-ziger Jahren gemessen und festgelegt worden ist und somit auch heute noch Grundlage der Planungen von Funkverbindungen ist. Ziel von ENAMS ist es, den momentanen Zustand der MMN-Störpegel in diesen Kategorien statistisch gesichert zu erfassen und zu beschreiben, welche Änderungen über das Jahr und in den kommenden Jahren auftreten. Finanziert wurde das Projekt bisher vom Deutschen Amateurradio Club (DARC) und aus privater Initiative und Firmenspenden. Inzwischen sind auch europäische und außereuropäische Standorte (USA, Neuseeland) hinzugekommen und haben den Betrieb aufgenommen.

description: The observation of the neutrinoless double beta decay may provide essential information on the nature of neutrinos. Among the current experimental approaches, a high pressure gaseous TPC is an attractive option for the search of double beta decay due to its good energy resolution and the detailed topological information of each event. We present in this talk a detailed study of the ionization topology of the 136Xe double beta decay events in a High Pressure Xenon TPC, as well as that of the typical competing backgrounds. We define some observables based on graph theory concepts to develop automated discrimination algorithms. Our criteria are able to reduce the background level by about three orders of magnitude in the region of interest of the 136Xe Qbb for a signal acceptance of 40%. This result provides a quantitative assessment of the benefit of topological information offered by gaseous TPCs for double beta decay search, and proves that it is a promising feature in view of future experiments in the field. Possible ideas for further improvement in the discrimination algorithms and the dependency of these results with the gas diffusion and readout granularity will be also discussed.

Due to these properties, they face distinct information security threats. Security of the data flowing through across networks provides the researchers with an interesting and intriguing potential for research. Design of these networks to ensure the protection of data faces the constraints of limited power and processing resources. We provide the basics of wireless sensor network security to help the researchers and engineers in better understanding of this applications field. In this chapter, we will provide the basics of information security with special emphasis on WSNs. The chapter will also give an overview of the information security requirements in these networks. Threats to the security of data in WSNs and some of their counter measures are also presented.

description: Cellulosic materials present as tissue, paper, wood, or filter materials in low and intermediate level waste will degrade under alkaline conditions if water ingresses in a cementitious backfilled repository. The main degradation product is isosaccharinic acid. Complex formation with isosaccharinic acid may adversely affect the retention of radionuclides by the sorption or formation of solid phases. Hence, this compound is of particular concern in the context of nuclear waste disposal. Structural information of complexes is limited to spherical metal centers and little is known about the interaction of uranyl (UVIO22+) with isosaccharinic acid. Therefore, the interaction of UO22+ with α-isosaccharinate (ISA) was studied under acidic conditions focusing particularly on the structural characterization of the formed complexes. Attenuated total reflection Fourier-transform infrared (ATR-FTIR), nuclear magnetic resonance (NMR), UV-Vis, extended X-ray absorption fine structure (EXAFS) spectroscopy and electrospray-ionization mass spectrometry (ESI-MS) were combined with theoretical calculations to obtain a process understanding on the molecular level. The dominant binding motifs in the formed complexes are 5- and 6-membered rings involving the carboxylic group as well as the α- or β-hydroxy group of ISA. Two concentration dependent complex formation mechanisms were identified involving either mono- ([UO2(ISA)(H2O)3]+) or binuclear ([(UO2)2(ISA)(H2O)6]3+) species. Furthermore, this study unveils the interaction of UO22+ with the protonated α-isosaccharinic acid (HISA) promoting its transformation to the corresponding α-isosaccharinate-1,4-lactone (ISL) and inhibiting the formation of polynuclear UO22+–ISA species. Future studies on related systems will benefit from the comprehensive knowledge concerning the behavior of ISA as a complexing agent gained in the present study.

description: Cloud computing has achieved an unbelievable adoption response rate but still its infancy stage is not over. It is an emerging paradigm and amazingly gaining popularity. The size of the market shared of the applications provided by cloud computing is still not much behind the expectations. It provides the organizations with great potential to minimize the cost and maximizes the overall operating effectiveness of computing required by an organization. Despite its growing popularity, still it is faced with security, privacy, and portability issues, which in one or the other way create hurdles in the fast acceptance of this new technology for the computing community. This paper provides a concise all around analysis of the challenges faced by cloud computing community and also presents the solutions available to these challenges.

description: Die Nachvollzieh- und Nutzbarkeit der rasant ansteigenden Menge digitaler Forschungsdaten wird seit einiger Zeit als eine zentrale strategische Herausforderung für die Leitungsebene von Universitäten gesehen. Bei der zentralen Koordination und der Umsetzung diesbezüglicher Konzepte in den Universitäten muss u. a. der bestehende Fächerkanon der jeweiligen Universität berücksichtigt werden. Vor diesem Hintergrund beschäftigt sich die vorliegende Arbeit speziell mit den Forschungsdaten-Repositorien des Fachbereichs Biologie. Folgende Fragen werden beleuchtet: (a.) Wie stark werden Forschungsdaten-Repositorien an den zehn renommiertesten biologischen Fakultäten in Deutschland genutzt? (b.) Welche Rolle übernehmen Bibliotheken an der Bereitstellung und im Service von biowissenschaftlichen Forschungsdaten-Repositorien? Die Daten für die vorliegende Arbeit wurden mittels einer Befragung der zehn renommiertesten Fakultäten Deutschlands und den zuständigen Bibliotheken per E-Mail erhoben.

title: Paradigmenwechsel im Personalmanagement unter dem Vorzeichen von Generationswechsel: Wandel der Mitarbeiterführung in Zeiten der digitalen Gesellschaft
Creators: name: Merkler, Benjamin
Publisher: name: University Library Heidelberg
Year: 2015

description: Aufgrund einer rasanten technologischen Entwicklung und unter dem Einfluss verschiedenster historisch-gesellschaftlicher Umbrüche hat sich auch die Vorstellung geändert, wie Unternehmen funktionieren und wie die Arbeitswelt organisiert sein sollte. Es lassen sich gewisse Tendenzen erkennen, die sich mittels einer Einteilung in verschiedene Generationen recht gut erklären lassen. Daher geht dieser Beitrag der Frage nach, wie sich die verschiedenen Generationen einerseits voneinander abgrenzen lassen und welche spezifischen Ansprüche sie jeweils an die Arbeitswelt stellen. Zudem werden Ansatzpunkte aufgezeigt, wie man auf diese Veränderungen reagieren kann. Zentral ist dabei darauf zu achten, dass man den unterschiedlichen Gruppen gleichermaßen gerecht wird und versucht durch einen intensiven Austausch etwaige Spannungen, die zwischen den verschiedenen Altersgruppen entstehen können, aus dem Weg zu räumen. Insbesondere Fragestellungen der Kommunikation, der Organisation sowie der Mitarbeiterführung sind hierbei von großem Interesse. Es kommt darauf an, die Heterogenität der Mitarbeiter so zu nutzen, dass alle Beteiligten und nicht zuletzt das Unternehmen als Ganzes einen Gewinn erzielen.

description: Marginal changes in geometrical dimensions due to temperature changes affect the performance of optical instruments. Highly dimensionally stable materials can minimize these effects since they offer low coefficients of thermal expansion (CTE). Our dilatometer, based on heterodyne interferometry, is able to determine the CTE in 10−8 K−1 range. Here, we present the improved interferometer performance using angular measurements via differential wavefront sensing to correct for tilt-to-length coupling. The setup was tested by measuring the CTE of a single-crystal silicon at 285 K. Results are in good agreement with the reported values and show a bias of less than 1%.

description: Interkulturelle Kompetenz ist in unserer zunehmend heterogenen Gesellschaft gerade in Bibliotheken, wo unter verschiedensten Bevölkerungsgruppen auch Mitglieder unterschiedlicher Kulturen aufeinander treffen, eine unerlässliche Fähigkeit. Ihre Wichtigkeit im betriebswirtschaftlichen Kontext wird, zusammen mit anderen Eigenschaften und Fertigkeiten, im Rahmen des Personalmanagementkonzepts "Diversity Management" wissenschaftlich erforscht. Nach einer kurzen Einführung in das Konzept der "Diversity" im wirtschaftlichen Rahmen und einer historischen Betrachtung des darauf abzielenden Managementkonzepts beleuchtet dieser Beitrag die Zusammenhänge zwischen den genannten Konzepten, verschiedenen Kulturbegriffen und Interkultureller Kompetenz. Abschließend werden speziell in Bibliotheken auftretende, kulturell bedingte Problemfelder aufgezeigt und Maßnahmen vorgestellt, mit denen im Rahmen eines modernen Personalmanagements Konflikte reduziert und Betriebsklima sowie Mitarbeitermotivation verbessert werden können.

description: The study of biodiversity, growth, development, and metabolism of cultivated microorganisms is an integral part of modern microbiological, biotechnological, and medical research. Such studies require the development of new methods of isolation, cultivation, manipulation, and study of individual bacterial cells and their consortia. To this end, in recent years, there has been an active development of different isolation and three-dimensional cell positioning methods. In this review, the optical tweezers, surface heterogeneous functionalization, multiphoton lithography, microfluidic techniques, and laser printing are reviewed. Laser printing is considered as one of the most promising techniques and is discussed in detail.

description: We present the first long \emph{Suzaku} observation of the hyperluminous infrared galaxy IRAS 09104+4109 which is dominated by a Type 2 AGN. The infrared to X-ray SED indicates that the source is an obscured quasar with a Compton-thin absorber. However, the 3$σ$ hard X-ray detection of the source with the \emph{BeppoSAX} PDS suggested a reflection-dominated, Compton-thick view. The high-energy detection was later found to be possibly contaminated by another Type 2 AGN, NGC 2785, which is only 17 arcmin away. Our new \emph{Suzaku} observation offers simultaneous soft and hard X-ray coverage and excludes contamination from NGC 2785. We find that the hard X-ray component is not detected by the \emph{Suzaku} HXD/PIN (effective energy band 14-45 keV). Both reflection and transmission models have been tested on the latest \emph{Suzaku} and \emph{Chandra} data. The 0.5-10 keV spectrum can be well modelled by the two scenarios. In addition, our analysis implied that the absorption column required in both models is $N_{\rm H} \sim 5 \times 10^{23}$ cm$^{-2}$. Unless IRAS 09104+4109 is a "changing-look" quasar, we confirm that it is a Compton-thin AGN. Although the lack of detection of X-ray emission above 10 keV seems to favour the transmission scenario, we found that the two models offer fairly similar flux predictions over the X-ray band below $\sim$ 40 keV. We also found that the strong iron line shown in the \emph{Suzaku} spectrum is in fact a blend of two emission lines, in which the 6.4 keV one is mostly contributed from the AGN and the 6.7 keV from the hot cluster gas. This implies that the neutral line is perhaps caused by disc reflection, and the reflection-dominated model is more likely the explanation. The transmission model should not be completely ruled out, but a deeper hard X-ray spectrum observation is needed to discriminate between the two scenarios.
