description: The high-redshift 21 cm signal from the Epoch of Reionization (EoR) is a promising observational probe of the early universe. Current- and next-generation radio interferometers such as the Hydrogen Epoch of Reionization Array (HERA) and Square Kilometre Array (SKA) are projected to measure the 21 cm auto power spectrum from the EoR. Another observational signal of this era is the kinetic Sunyaev-Zel'dovich (kSZ) signal in the cosmic microwave background (CMB), which will be observed by the upcoming Simons Observatory (SO) and CMB-S4 experiments. The 21 cm signal and the contribution to the kSZ from the EoR are expected to be anti-correlated, the former coming from regions of neutral gas in the intergalactic medium and the latter coming from ionized regions. However, the naive cross-correlation between the kSZ and 21 cm maps suffers from a cancellation that occurs because ionized regions are equally likely to be moving toward or away from the observer and so there is no net correlation with the 21 cm signal. We present here an investigation of the 21 cm-kSZ-kSZ bispectrum, which should not suffer the same cancellation as the simple two-point cross-correlation. We show that there is a significant and non-vanishing signal that is sensitive to the reionization history, suggesting the statistic may be used to confirm or infer the ionization fraction as a function of redshift. In the absence of foreground contamination, we forecast that this signal is detectable at high statistical significance with HERA and SO. The bispectrum we study suffers from the fact that the kSZ signal is sensitive only to Fourier modes with long-wavelength line-of-sight components, which are generally lost in the 21 cm data sets owing to foreground contamination. We discuss possible strategies for alleviating this contamination, including an alternative four-point statistic that may help circumvent this issue.

description: We compute pseudoscalar meson masses and decay constants in partially quenched QCD with three dynamical flavors of improved staggered quarks. Fitting the lattice data to staggered chiral perturbation theory forms and extrapolating in quark mass and lattice spacing, we find: $f_π= 129.5 \pm 0.9 \pm 3.5$ MeV, $f_K = 156.6 \pm 1.0 \pm 3.6$ MeV, and $f_K/f_π= 1.210(4)(13)$. The value for $f_K/f_π$ implies $|V_{us}|=0.2219(26)$. We also obtain $m_u/m_d = 0.43(0)(1)(8)$, or, with more input on electromagnetic effects from the continuum, $m_u/m_d = 0.41(0)(1)(4)$. Using the one-loop perturbative mass renormalization, we determine $m_u$ and $m_d$ in the MSbar scheme.

description: The black holes detected by current and future interferometers can have diverse origins. Their expected mass and spin distributions depend on the specifics of the formation mechanisms. When a physically motivated prior distribution is used in a Bayesian inference, the parameters estimated from the gravitational-wave data can change significantly, potentially affecting the physical interpretation of certain gravitational-wave events and their implications on theoretical models. As a case study we analyze primordial black holes, which might be formed in the early universe and could comprise at least a fraction of the dark matter. If accretion is not efficient during their cosmic history, primordial black holes are expected to be almost non-spinning. If accretion is efficient, massive binaries tend to be symmetrical and highly spinning. We show that incorporating these priors can significantly change the inferred mass ratio and effective spin of some binary black hole events, especially those identified as high-mass, asymmetrical, or spinning by a standard analysis using agnostic priors. For several events, the Bayes factors are only mildly affected by the new priors, implying that it is hard to distinguish whether merger events detected so far are of primordial or astrophysical origin. In particular, if binaries identified by LIGO/Virgo as strongly asymmetrical (including GW190412) are of primordial origin, their mass ratio inferred from the data can be closer to unity. For GW190412, the latter property is strongly affected by the inclusion of higher harmonics in the waveform model.

description: We model the mass distributions of 40 high surface brightness spiral galaxies inside their optical radii, deriving parameters of mass models by matching the predicted velocities to observed velocity maps. We use constant mass-to-light disk and bulge models, and we have tried fits with no halo and with three different halo density profiles. The data require a halo in most, but not all, cases, while in others the best fit occurs with negligible mass in the luminous component, which we regard as unphysical. All three adopted halo profiles lead to fits of about the same quality, and our data therefore do not constrain the functional form of the halo profile. The halo parameters display large degeneracies for two of the three adopted halo functions, but the separate luminous and dark masses are better constrained. However, the fitted disk and halo masses vary substantially between the adopted halo models, indicating that even high quality 2-D optical velocity maps do not provide significant constraints on the dark matter content of a galaxy. We demonstrate that data from longslit observations are likely to provide still weaker constraints. We conclude that additional information is needed in order to constrain the separate disk and halo masses in a galaxy.

description: Poland’s accession to the EU led to rapid adjustments in the Polish food sector. Opening the enormous common European market, with over 450 million consumers, forced the processing industry to face an extreme competition, while creating at the same time an increased outlet opportunity. Customs barriers ceased to stand in the way and the price and quality of products, as well as good management, became necessary key factors of achieving a market success. Since the Poland’s accession to the European Union the number of livestock products processing plants having an export licence for the extended European market has increased significantly. There are ca. 1800 such plants at the moment. Exports of meat and meat products as well as dairy and fish products increased from EUR 2.3 billion in 2003 to ca. EUR 7.9 billion in 2007, i.e. almost three times, despite the strengthening PLN against Euro. / Synopsis.

Przestały obowiązywać bariery celne, a cena i jakość produktu oraz sprawność działania kadry zarządzającej stały się kluczowymi elementami w odniesieniu sukcesu na rynku. Od wejścia Polski do Unii kilkakrotnie wzrosła liczba zakładów przetwórstwa produktów zwierzęcych z uprawnieniami eksportowymi na poszerzony rynek europejski. Jest ich obecnie około 1800. Eksport mięsa i jego przetworów, produktów mleczarskich i rybnych wzrósł z 2,8 mld zł w 2003 roku do około 7,9 mld zł w 2007 roku, tj. prawie 3-krotnie, pomimo umacniania się naszej waluty względem euro.
title: Complement Factor H Related Proteins and their Biological Role During Bacterial Infection
Creators: name: Lavender, Hayley Samantha
Publisher: name: The Open University
Year: 2017

description: Neisseria meningitidis is a major cause of meningitis and sepsis worldwide despite available polysaccharide and protein vaccines. Individuals with rare defects in the terminal complement pathway are susceptible to meningococcal disease but further genetic factors that contribute to disease susceptibility are less well understood. A genome wide association study has linked polymorphisms in the Complement Factor H (CFH) locus with meningococcal disease in the general population. CFH is a negative regulator of the alternative complement pathway whereas CFH-related proteins (CFHR), encoded in the CFH locus, act as antagonists of CFH. Investigations of the biological role of the CFHRs have been hampered by lack of reagents, therefore a panel of specific monoclonal antibody reagents to CFHR2-5 were generated and characterised.

 Previously, N. meningitidis has been shown to bind CFH via a surface exposed lipoprotein, factor H binding protein (fHbp), at high affinity. This study demonstrates that CFHR3 binds to the bacterial surface in a fHbp dependent-manner. Furthermore, CFHR3 competes with CFH for binding to fHbp. Bound CFHR3 increases susceptibility of N. meningitidis to complement-mediated lysis which was dependent on the sequence of the fHbp variant. The ability of N. meningitidis to evade the host immune system is likely to be determined by the relative levels of CFH and CFHR3 on the bacterial surface, providing a molecular mechanism for how variation in cfhr3 may predispose individuals to meningococcal disease.

 Furthermore this work demonstrates that Neisseria cinerea, which colonises the respiratory mucosa, expresses fHbp and binds CFH at similar affinities as meningococcal fHbp promoting bacterial survival in serum. The recently developed meningococcal vaccine, Bexsero®, includes fHbp as an antigen and antibodies elicited by Bexsero® are bactericidal against N. cinerea suggesting that the introduction of this vaccine could affect nasopharyngeal carriage of N. cinerea.

description: Seit 16 Jahren Leerstand im "Lichtspieltheater der Jugend"! Damals im Jahr 1910 ursprünglich erbaut als Etablissement für Tanzveranstaltungen mit musikalischer Untermalung. Seitdem ist viel passiert. So wurde das Gebäude im Zuge der blühenden Entwicklung der Filmindustrie zum Filmtheater umgebaut und in den 1950er Jahren erweitert. Bis es 1998 stillgelegt wurde. Nun steht das ehemalige "Lichtspieltheater der Jugend" an einem der prestigeträchtigsten Orte im Zentrum von Frankfurt (Oder) ohne Funktion und schreit förmlich nach einer Wiederbelebung. Die Aufgabe war der Umbau und die damit einhergehende Revitalisierung des Gebäudes. Der Schwerpunkt der Arbeit lag somit anfangs beim Bauen im Bestand. Bei der Auseinandersetzung mit dem Bestandsgebäude kamen jedoch bald zusätzliche Themen hinzu. So war die Betrachtung und die damit einhergehende Auseinandersetzung schrumpfender, ostdeutscher Städte unter dem Einfluss der DDR unvermeidbar. So gilt es nicht nur das Lichtspieltheater zu revitalisieren, sondern es zusätzlich um eine angemessene Funktionen zu erweitern. Ein Ort für urbane, öffentliche und kulturelle Funktionen, der auf unkonventionelle Art einen einzigartigen Anziehungspunkt schafft, um somit neue Impulse im Zentrum von Frankfurt (Oder) zu setzen.
description: For 16 years, vacancy in "Lichtspieltheater der Jugend"! Back in 1910, originally built as an establishment for danceevents with orchestramusic. Since then a lot has happened. In the 1950s the building was rebuilt to a movietheatre as a result of the booming development of the filmindustry. Until 1998, when it was closed. Now the former "Lichtspieltheater der Jugend" is located at one of the most prestigious places in the centre of Frankfurt ( Oder), it has no function and is screaming for a revival. The task was the reconstruction and the concomitant restoration of the building. Therefore the focus of the work was initially in existing buildings. With the examination of existing buildings, additional topics were added soon. So the observation of shrinking, eastgerman cities under the influence of the DDR was inevitable. So it is not only revitalize the movie theater, but also to expand it with an appropriate function. A place for urban, public and cultural functions, which creates in an unconventional way a unique attraction to exploring new initiatives in the centre of Frankfurt (Oder).

description: The European Union policy is more and more based on the sustainable development strategy which harmonizes the economic, social and ecological aspects of development. The key role of environmental protection in the sustainable development arises from the impact of environmental issues on the economic and civilization development. It is worth to say that the connection between the economic and social development as well as the natural environment was not noticed till 1960’s or 1970’s. The EU ecological policy emphasizes the need of integration of the environmental protection policy and the sectoral polices (including the agricultural policy). The aim of the paper is to recognize the compliance of the instruments of CAP with the environmental issues on which the Sustainable Agriculture and Rural Development is based. The paper presents the most important CAP reforms which emphasize the need to balance the ecological effects of agricultural production. The environmental aspects of CAP were analyzed from the Polish perspective. / Synopsis. Polityka Unii Europejskiej jest w coraz większym stopniu ukierunkowana na realizację strategii zrównoważonego rozwoju, która oznacza harmonizację ekonomicznych, społecznych i ekologicznych aspektów rozwoju. Szczególną rolę odgrywają tu kwestie ochrony środowiska, bowiem pojawiające się zagrożenia mogą w istotny sposób ograniczyü rozwój gospodarczy i cywilizacyjny przyszłych pokoleń. Warto podkreślić, że związki między rozwojem gospodarczym i społecznym a środowiskiem naturalnym dostrzeżono dopiero na przełomie lat 60. i 70. XX w. W polityce ekologicznej UE akcentuje się konieczność zintegrowania polityki ochrony środowiska z politykami sektorowymi, w tym z polityką rolną. Powstaje pytanie, czy istniejące instrumenty polityki rolnej UE są dobrze ukierunkowane z punktu widzenia celów środowiskowych, a zatem czy sprzyjają zrównoważonemu rozwojowi rolnictwa i obszarów wiejskich. W opracowaniu wskazano najważniejsze reformy WPR akcentujące potrzebę równoważenia skutków gospodarowania w rolnictwie na płaszczyźnie ekologicznej. Środowiskowe aspekty polityki rolnej UE pokazano z perspektywy Polski.
Molecular evolution of the parasitic green alga, Helicosporidium sp.
Creators: name: De Koning, Audrey Patricia
Publisher: name: University of British Columbia
Year: 2010

description: Helicosporidia are single-celled obligate endoparasites of invertebrates. They have a unique morphology and infection strategy, which make them unlike any other eukaryote. Molecular data were produced to clarify their phylogenetic relationship and to examine the evolution of their cryptic plastid. Phylogenetic analyses of 69 ribosomal proteins identified from an expressed sequence tag (EST) library showed that Helicosporidia are derived green algae and more specifically, are related to the trebouxiophyte algae. An obligate parasitic lifestyle is rare among plant and algal groups, and because Helicosporidium possesses no pigments and no chloroplast-like structure has been identified, photosynthetic ability has presumably been lost in this organism. I sought to examine the role that a relict plastid might play in Helicosporidium. I identified ESTs of 20 putatively plastid-targeted enzymes that are involved in a wide variety of metabolic pathways. As expected, no components of photosynthesis were found, but components of other metabolic pathways including sulfur metabolism and fatty acid, isoprenoid and heme biosynthesis suggest that Helicosporidium retains its plastid for these functions. The complete plastid genome of this species of Helicosporidium was sequenced and revealed only four protein-coding genes not involved in transcription or translation, with two of these confirming the metabolic functions suggested by the nuclear-encoded, plastid-targeted genes identified from the ESTs. In addition, the Helicosporidium plastid genome is one of the smallest known (37.5 kb). Its reduced size results from loss of many genes commonly found in plastids of other plants and algae (including all proteins that function in photosynthesis), elimination of duplicated genes and redundant tRNA isoacceptors, and minimization of intergenic spaces. The Helicosporidium plastid genome is also highly structured, with each half of the circular genome containing nearly all genes on one strand. Both the structure and content of the plastid genome and the deduced function of the organelle show parallels with the relict plastid found in the malaria parasite, Plasmodium falciparum. These unrelated organisms each evolved from photosynthetic ancestors, and the convergence in form and function of their relict plastids suggest that common forces shape plastid evolution, following the switch from autotrophy to parasitism.

description: Variational quantum algorithms are a leading candidate for early applications on noisy intermediate-scale quantum computers. These algorithms depend on a classical optimization outer-loop that minimizes some function of a parameterized quantum circuit. In practice, finite sampling error and gate errors make this a stochastic optimization with unique challenges that must be addressed at the level of the optimizer. The sharp trade-off between precision and sampling time in conjunction with experimental constraints necessitates the development of new optimization strategies to minimize overall wall clock time in this setting. In this work, we introduce two optimization methods and numerically compare their performance with common methods in use today. The methods are surrogate model-based algorithms designed to improve reuse of collected data. They do so by utilizing a least-squares quadratic fit of sampled function values within a moving trusted region to estimate the gradient or a policy gradient. To make fair comparisons between optimization methods, we develop experimentally relevant cost models designed to balance efficiency in testing and accuracy with respect to cloud quantum computing systems. The results here underscore the need to both use relevant cost models and optimize hyperparameters of existing optimization methods for competitive performance. The methods introduced here have several practical advantages in realistic experimental settings, and we have used one of them successfully in a separately published experiment on Google's Sycamore device.

description: We report first principles density functional studies using plane wave basis sets and pseudopotentials and all electron linear augmented plane wave (LAPW) of the relative stability of various ferroelectric and antiferroelectric supercells of PMN for 1:2 chemical ordering along [111] and [001]. We used linear response with density functional perturbation theory (DFPT) as implemented in the code ABINIT to compute the Born effective charges, electronic dielectric tensors, long wavelength phonon frequencies and LO-TO splittings. The polar response is different for supercells ordered along [111] and [001]. Several polar phonon modes show significant coupling with the macroscopic electric field giving giant LO-TO splittings. For [111] ordering, a polar transverse optic (TO) mode with E symmetry is found to be unstable in the ferroelectric P3m1 structure and the ground state is found to be triclinic. Multiple phonon instabilities of polar modes and their mode couplings provide the pathway for polarization rotation. The Born effective charges in PMN are highly anisotropic and this anisotropy contributes to the observed huge electromechanical coupling in PMN solid solutions.

description: We present the Stage II results from the ongoing Satellites Around Galactic Analogs (SAGA) Survey. Upon completion, the SAGA Survey will spectroscopically identify satellite galaxies brighter than $ M_{r,o} = -12.3 $ around 100 Milky Way (MW) analogs at $ z \sim 0.01 $. In Stage II, we have more than quadrupled the sample size of Stage I, delivering results from 127 satellites around 36 MW analogs with an improved target selection strategy and deep photometric imaging catalogs from the Dark Energy Survey and the Legacy Surveys. We have obtained 25,372 galaxy redshifts, peaking around $ z = 0.2 $. These data significantly increase spectroscopic coverage for very low redshift objects in $ 17 < r_o < 20.75 $ around SAGA hosts, creating a unique data set that places the Local Group in a wider context. The number of confirmed satellites per system ranges from zero to nine, and correlates with host galaxy and brightest satellite luminosities. We find that the number and the luminosities of MW satellites are consistent with being drawn from the same underlying distribution as SAGA systems. The majority of confirmed SAGA satellites are star forming, and the quenched fraction increases as satellite stellar mass and projected radius from the host galaxy decrease. Overall, the satellite quenched fraction among SAGA systems is lower than that in the Local Group. We compare the luminosity functions and radial distributions of SAGA satellites with theoretical predictions based on cold dark matter simulations and an empirical galaxy-halo connection model and find that the results are broadly in agreement.

Sowohl in der wissenschaftlichen Literatur als auch in der Praxis stellt sich die Frage, wie man Ziele und operative unterstützende Maßnahmen setzen kann, um Nachhaltigkeit zu erreichen. Insbesondere, da Mitarbeiter einen hohen Betrag für Nachhaltigkeit liefern können, sollen diese so früh wie möglich mit Nachhaltigkeitsideen in Kontakt treten. Dies soll in Form eines Nachhaltigkeitscurriculum geschehen, welche im Folgenden vorgestellt wird. Im Nachhaltigkeitscurriculum werden im Bereich des Facility Managements, Ziele und operative Maßnahmen aufgezeigt. Die Vorgehensweise geschieht in Form eines Storybords. Global Bike Incorporated (GBI) will einen CSR Report erstellen. Die verantwortlichen Mitarbeiter habe eine erste Analyse durchgeführt und festgestellt, dass sie weder ein System noch eine Systematik haben, um Nachhaltigkeit zu messen und dadurch einen CSR Report zu erstellen. Als ersten Schritt analysieren sie mögliche Inhalte eines CSR Report und leiten für sich passende Ziele ab. Einer dieser Ziele die sie ableiten, ist die Reduktion des Energieverbrauchs um 10%. In weitere Folge wollen die Verantwortlichen operative Maßnahmen ableiten. Sie stellen jedoch fest, dass sie dazu passende Messzähler benötigen, die den Verbrauch messen. Also installieren sie an allen relevanten Stellen der Gebäude passende Stromverbrauchszähler. Weiters bilden sie die Gebäudestruktur und die Messzähler im SAP System ab. In einem weiteren Schritt erfassen sie die Zählerstände. Anhand der nun möglichen Berichte stellen sie fest, dass eine Klimaanlage nicht kosteneffizient ist und entscheiden sich für einen Anlagentausch. In weiterer Folge stellen die Mitarbeiter von GBI fest, dass vorbeugende Instandhaltung den Energieverbrauch um ca. 10% senken kann. Dafür benötigen sie einen Wartungsplan mit Aktivitäten und einer Zeitintervallsplanung. Diese Maßnahmen dienten der ökologischen Dimension des CSR. Da es auch eine soziale Dimension gibt beschließen sie, die Mitarbeiterzufriedenheit zu heben, indem sie die Mitarbeiter durch das SAP System servicieren. Sie setzen daher einen neuen, durch das SAP System unterstützten, Störungsprozess auf. Im Rahmen des Curriculums werden 3 Störungsprozesse durchgespielt: 1. Ein Raum ist kalt und die Heizung muss entlüftet werden. 2. Austausch eines defekten Sessels, durch Ankauf eines Neuen. 3. Ausmalen von Wänden durch einen externen Dienstleister Nun kann GBI für dieses Geschäftsjahr einen CSR Report vorlegen und aufzeigen, wie Nachhaltig das Unternehmen ist.

description: In models with extra dimensions that accommodate a TeV-scale gravity, small black holes could be produced in near future accelerator experiments. Such small black holes, whose gravitational radius is mush smaller than the characteristic size of extra dimensions (compactification radius in flat or AdS radius in warped extra dimensions) can be very well described by asymptotically flat solutions, thus losing the information about the global geometry of the extra manifold. One might conclude that such small black holes would be indistinguishable in different scenarios. We argue that important differences still exist, especially regarding experimental signature in colliders, which may help us distinguish between the various extra dimensional scenarios. The main differences come from the fact that most of the models with the warped extra dimension have an additional discrete $Z_2$ symmetry that makes the brane behave as if it were an infinite tension brane.

Extragalactic Water Masers, Geometric Estimation of H_o and Characterization of Dark Energy
Creators: name: Greenhill, L. J.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: High precision estimation of the equation of state of dark energy depends on constraints external to analyses of Cosmic Microwave Background fluctuations. A geometric estimation of the local expansion rate, H_o, would provide the most direct and robust constraint. Traditional techniques to estimate H_o have depended on observations of standard candles for which systematic effects can be 10% or more. Observations of water maser sources in the accretion disks that feed the central engines of active galaxies enable simplified, robust, and largely geometric analyses. Many thousand maser sources will be discovered in studies with the SKA, owing to its great sensitivity. Spectroscopic monitoring and interferometric mapping - with intercontinental baselines - will allow estimation of H_o to 1% and possibly better.

description: We give a classification up to equivalence of the fine group gradings by abelian groups on the Kantor pairs and triple systems associated to Hurwitz algebras (i.e., unital composition algebras), under the assumption that the base field is algebraically closed of characteristic different from 2. The universal groups and associated Weyl groups are computed. We also determine, in the case of Kantor pairs, the induced (fine) gradings on the associated Lie algebras given by the Kantor construction.

description: Purpose of the study is an estimation of the trade quality of local fruit traded in the local market in the context of the EUrequirements. The estimation has been done for the primary market in the Lublin voivodeship. The study has shown that the analysed producers provide fruit of very different trade quality. Arbitrariness of estimation of the fruit quality indicates that the declared class of quality is not homogeneous in case of various participants in the market, and moreover it does not reach the specified standard. The surveyed suppliers treated the issue of homogeneousness of fruit and labelling it in an individual way. Therefore the results of the analyses do not allow for a positive evaluation of the trade quality of fruit of domestic origin in the light of current standards. The predominant opinion of a great importance of standards in increasing the quality of fruit is not reflected in the Lublin wholesale market. / Synopsis. Celem pracy jest ustalenie aktualnego poziomu jakości handlowej krajowych owoców znajdujących się na rynku w świetle obowiązujących przepisów Unii Europejskiej. Oceny dokonano na poziomie rynku pierwotnego na przykładzie województwa lubelskiego. Z badań wynika, że badani producenci dysponują owocami bardzo zróżnicowanymi pod względem jakości handlowej. Dowolność w ocenie poziomu jakości owoców wskazuje, że deklarowana klasa jakości nie jest jednoznaczna u poszczególnych uczestników obrotu, jak również nie jest jednoznaczna z określoną normą europejską. Badani producenci w różnym stopniu dbają również o jednorodność owoców w opakowaniu oraz o właściwe etykietowanie owoców. Wyniki analiz nie pozwalają na wysoką ocenę jakości handlowej owoców krajowej produkcji w świetle obowiązujących standardów, a powszechne przekonanie o ogromnej roli norm w podnoszeniu jakości nie znalazło odzwierciedlania na rynku lubelskim.
A matrix model for a quantum hall droplet with manifest particle-hole symmetry

description: We find that a gauged matrix model of rectangular fermionic matrices (a matrix version of the fermion harmonic oscillator) realizes a quantum hall droplet with manifest particle-hole symmetry. The droplet consists of free fermions on the topology of a sphere. It is also possible to deform the Hamiltonian by double trace operators, and we argue that this device can produce two body potentials which might lead the system to realize a fractional quantum hall state on the sphere. We also argue that a single gauged fermionic quantum mechanics of hermitian matrices realizes a droplet with an edge that has $c=1/2$ CFT on it.

Anisotropic circular photogalvanic effect in colloidal tin sulfide nanosheets

description: Tin sulfide promises very interesting properties such as a high optical absorption coefficient and a small band gap, while being less toxic compared to other metal chalcogenides. However, the limitations in growing atomically thin structures of tin sulfide hinder the experimental realization of these properties. Due to the flexibility of the colloidal synthesis, it is possible to synthesize very thin and at the same time large nanosheets. Electrical transport measurements show that these nanosheets can function as field-effect transistors with high on/off ratio and p-type behavior. The temperature dependency of the charge transport reveals that defects in the crystal are responsible for the formation of holes as majority carriers. During illumination with circularly polarized light, these crystals generate a helicity dependent photocurrent at zero-volt bias, since their symmetry is broken by asymmetric interfaces (substrate and vacuum). Further, the observed circular photogalvanic effect shows a pronounced in-plane anisotropy, with a higher photocurrent along the armchair direction, originating from the higher absorption coefficient in this direction. Our new insights show the potential of tin sulfide for new functionalities in electronics and optoelectronics, for instance as polarization sensors.
