description: We analyse \textit{ROSAT} and \textit{Chandra} ACIS X-ray observations and HI absorption spectra of the $γ$ Cygni supernova remnant (G78.2+2.1, DR4). The \textit{ROSAT} All-Sky-Survey image shows G78.2+2.1 has an adjacent limb-brightened shell north of it. A new \textit{ROSAT} mosaic shows details of the X-ray emission over the entire face of G78.2+2.1. We also create \textit{Chandra} mosaics which cover much of the northern rim and central regions of G78.2+2.1. HI absorption spectra result in association of G78.2+2.1 with the $γ$ Cygni nebula, with distance 1.7 to 2.6 kpc. Chandra spectra for G78.2+2.1 give an X-ray temperature of 0.6-1.2 keV (90% error), and that a Sedov model has age of 6800-10000 yr. A compact power-law X-ray source in G78.2+2.1 is consistent with the same distance as G78.2+2.1. The northern X-ray shell is identified with a B3 star at distance of 980 pc and is proposed as a stellar wind bubble.

description: Core-level photoelectron spectroscopy of molecules presents unique opportunities but also challenges in the Hard X-ray Spectroscopy (HAXPES) realm. Here we focus on the manifestation of the photoelectron recoil effects in core-level photoemission spectra, using the independent normal-mode oscillators approach that allows to model and investigate the resulting recoil lineshapes for molecules of large sizes with only a slight computational effort. We model the recoil lineshape for N 1s and C 1s photoemission using the 10-aminodecane-1-thiol molecule as an example. It represents also a class of compounds commonly used in creating self-assembled monolayers (SAMs) on surfaces. Attachment of the -SH head group to the surface is modelled here in a simplified way by anchoring the sulfur atom of a single molecule. The effects of the orientation of photoemission in the molecular frame on the recoil lineshape of such anchored molecules are illustrated and discussed as a possible geometry probe. Time-evolution of the recoil excitations from the initial emission site across the entire molecule is also visualized.

description: Using an $sp^{3}s^{*}$ tight-binding model we demonstrate how the observed strong bowing of the band gap and spin-orbit-splitting with increasing Bi composition in the dilute bismide alloy GaBi$_{x}$As$_{1-x}$ can be described in terms of a band-anticrossing interaction between the extended states of the GaAs valence band edge and highly localised Bi-related resonant states lying below the GaAs valence band edge. We derive a 12-band $\textbf{k}\cdot\textbf{p}$ Hamiltonian to describe the band structure of GaBi$_{x}$As$_{1-x}$ and show that this model is in excellent agreement with full tight-binding calculations of the band structure in the vicinity of the band edges, as well as with experimental measurements of the band gap and spin-orbit-splitting across a large composition range. Based on a tight-binding model of GaBi$_{x}$N$_{y}$As$_{1-x-y}$ we show that to a good approximation N and Bi act independently of one another in disordered GaBi$_{x}$N$_{y}$As$_{1-x-y}$ alloys, indicating that a simple description of the band structure is possible. We present a 14-band $\textbf{k}\cdot\textbf{p}$ Hamiltonian for ordered GaBi$_{x}$N$_{y}$As$_{1-x-y}$ crystals which reproduces accurately the essential features of full tight-binding calculations of the band structure in the vicinity of the band edges. The $\textbf{k}\cdot\textbf{p}$ models we present here are therefore ideally suited to the simulation of the optoelectronic properties of these novel III-V semiconductor alloys.

description: As evidence for the ER=EPR conjecture, it has recently been observed that the string that is holographically dual to an entangled quark-antiquark pair separating with (asymptotically) uniform acceleration has a wormhole on its worldsheet. We point out that a two-sided horizon and a wormhole actually appear for much more generic quark-antiquark trajectories, which is consistent with the fact that the members of an EPR pair need not be permanently out of causal contact. The feature that determines whether the causal structure of the string worldsheet is trivial or not turns out to be the emission of gluonic radiation by the dual quark and antiquark. In the strongly-coupled gauge theory, it is only when radiation is emitted that one obtains an unambiguous separation of the pair into entangled subsystems, and this is what is reflected on the gravity side by the existence of the worldsheet horizon.

description: Epithelial ovarian cancer (EOC) is the leading cause of gynecological cancer-related death. The high mortality and morbidity associated with EOC are mostly due to late diagnosis and chemotherapy drug resistance. Currently, the standard first-line chemotherapy regimen is systemic administration of platinum-based chemotherapy combined with a taxane. A major problem besides cisplatin resistance (occurring in nearly one-third of patients) is the greater toxicity of the drug combinations. A synergistic treatment with drug supporting activity could maximize the cytotoxic effects of chemotherapeutic agents on tumor cells while decreasing the dosage of each drug to potentially reduce toxicity. The ALDH-blocking agent Disulfiram (DSF), a clinically approved drug used for alcoholism treatment, has displayed promising anti-cancer activity. We previously described that blocking ALDH activity enhances the induction of apoptosis, especially in ovarian cancer stem cells treated with chemotherapeutic agents. In this study, we further investigated the synergistic effect of DSF in combination with cytotoxic chemotherapeutic drugs. The concentration of each chemotherapeutic agent could be significantly reduced with sustained efficacy on tumor cell apoptosis in cell lines in vitro (Dose-Reduction Index at IC50 from 1 to 50). Moreover, the potential chemo-sensitizing effects of DSF on ALDH-associated cisplatin-resistant ovarian cancer stem cells were also investigated and shown that in contrast to its high resistance to cisplatin, the cisplatin-resistant cells remain very sensitive to DSF-induced cytotoxicity (apoptosis and necrosis: cisplatin-resistant cells vs. parental cells: 60.4% vs. 20.5%). In combination with DSF and cisplatin, relatively more apoptosis and necrosis were induced in cisplatin-resistant cells than in their parental cells (apoptosis and necrosis: cisplatin-resistant cells vs. parental cells: 81.5% vs. 50.1%). A transcriptome analysis identified that ALDH was mainly enriched in the cancer-associated fibroblasts and showed that ALDH plays roles in responding to oxidative stress, metabolisms, and energy transition in the ALDH-associated cisplatin-resistant ovarian cancer stem cells. In conclusion, our data demonstrate a key role of ALDH-associated cisplatin-resistant cancer stem cells and identifies DSF as a potential adjuvant for a rational protocol design by computational quantitative assessment in vitro on ovarian cancer cell lines. Our work contributes to resolving the ALDH-associated cisplatin resistance and provides a resource for the development of novel chemotherapeutic regimens.

description: We have investigated the X-ray and $γ$-ray properties of the redback millisecond pulsar PSR J1723-2837 with XMM-Newton, Chandra and Fermi. We have discovered the X-ray orbital modulation of this binary system with the minimum that coincides with the phases of radio eclipse. The X-ray emission is clearly non-thermal in nature which can be well described by a simple power-law with a photon index of $\sim1.2$. The phase-averaged luminosity is $\sim9\times10^{31}$ erg/s in 0.3-10 keV which consumes $\sim0.2\%$ of the spin-down power. We have detected the $γ-$ray emission in $0.1-300$ GeV from this system at a significance of $\sim6σ$ for the first time. The $γ-$rays in this energy range consumes $\sim2\%$ of the spin-down power and can be modeled by a power-law with a photon index of $\sim2.6$. We discuss the high energy properties of the new redback in the context of a intrabinary shock model.

Common Bantoid verb extensions
Creators: name: Hyman, Larry M.
Publisher: name: Zenodo
Year: 2018

description: In this paper I survey verb extensions within different Bantoid languages and sub-
 groups, comparing them to Cameroonian Bantu zone A. Extending my survey of
 Niger-Congo extensions (Hyman 2007), I show that there is a band of contiguous
 languages in the Grassfields area where a number of contrastive verb extensions
 have relative productivity (cf. the studies in Idiata & Mba 2003). Interestingly, the
 languages in question belong to several subgroups: Limbum (NE Eastern Grass-
 fields Bantu), Noni (Beboid), Kom and Babanki (Ring Western Grassfields Bantu),
 Bafut and Mankon (Ngemba Eastern Grassfields Bantu). Other languages in these
 same subgroups are not in this geographical band and have very few extensions.
 The above-mentioned languages allow a possible reconstruction of *CV extensions
 with *s, *t, *n, *l, *k, and *m. A major property of Bantoid extensions is the rela-
 tive frequency of aspectual-type extensions, especially marking different types of
 pluractionality (iterative, frequentative, distributive, repetitive), diminutive (atten-
 uation of action), and intensive (augmentation of action) semantics. In many lan-
 guages the same suffix form covers two or more of these functions. The hypothesis
 is that the original system was more like Proto-Bantu, with extensions being more
 valence-related, but over time these very same extensions became reinterpreted
 as aspectual. However, the great variety of extensions in and outside of Bantoid
 suggests that there may have been more extensions at a pre-Proto-Bantu stage.

description: Purpose: To report and compare the results of endovascular and open surgical treatment for erosion bleeding of visceral arteries following pancreatitis and pancreatic surgery. Materials and Methods: This retrospective study included 65 consecutive patients (46 males, mean age 63 +/- 14 years) presenting with visceral artery erosions between January 2011 and December 2020. Endpoints were technical success, freedom from reintervention, stent-graft-related complications, and 30-day and one-year mortality. Results: The causes of erosion bleeding included complications of surgical treatment for the pancreas and upper gastrointestinal tract (75%), pancreatitis (19%), and spontaneous bleeding (6%). Pancreatectomy was performed in 34 (52%) patients, representing 2% of all pancreatectomy procedures (n = 1645) performed in our hospital during the study period. A total of 37 (57%) patients underwent endovascular treatment (EVT), and 28 (43%) patients had open surgery (OS) as a primary treatment. Eight of 37 (22%) patients in the EVT group underwent stent-graft treatment of the eroded vessels and 28 (78%) coil embolization. Six (9%) patients underwent reintervention with no significant differences between EVT and OS groups (11% vs. 7%, p = 0.692). Postoperative morbidity and complications in 52% of all patients were higher in the OS group than in the EVT group (41% vs. 68%, p = 0.029). The in-hospital 30-days mortality rate for all patients was 25%, and it was higher in the OS group than in the EVT group (14% vs. 39%, p = 0.017). Conclusions: An endovascular-first strategy for treating visceral arteries erosions may be preferred to reduce the complications associated with open surgery if patients are hemodynamically stable and have no anastomotic insufficiency. Endovascular treatment may be associated with better in-hospital survival when compared to primary open surgery. Further studies are required to identify the optimal approach.

description: Recently published data suggest a possible solar influence on some nuclear decay rates, including evidence for an annual variation attributed to the varying Earth-Sun distance. Here, we consider the possibility that the annual signal seen by the DAMA collaboration, and interpreted by them as evidence for dark matter, may in fact be due to the radioactive contaminant K-40, which is known to be present in their detector. We also consider the possibility that part of the DAMA signal may arise from relic big-bang neutrinos.

description: The ?6?2? neuronal nicotinic acetylcholine receptor (nAChR) subtype expressed in the dopaminergic mesostriatal pathway mediates many behavioural effects of nicotine, and is selectively blocked by the small disulfide-rich ?-conotoxins PIA and MII. Both share a "?-shaped" topology but PIA bears a tail in the N-terminal region containing three amino acids [arginine (R), aspartic acid (D), and proline (P)]. We synthesised a group of PIA-related peptides in which R1 was mutated or the RDP motif was gradually removed. Binding and functional studies showed that the RDP sequence is essential for the activity of PIA on the native rat ?6?2* subtype, with a major role played by residue R1. Molecular modelling studies showed that recognition of PIA by ?6?2* nAChRs depends on a salt bridge between the guanidine group of R1 and the highly negatively charged D166-D167 residues located on the ?2 subunit. The RDP sequence was then added to the N-terminus of MII; the resulting hybrid peptide (RDP-MII) showed an increased potency (5-fold) and affinity (13-fold) for ?6?2* but not for ?3?2* nAChRs. Furthermore, as docking studies indicated E11 as a potential key residue engendering a ?6?2* vs. ?3?2* selectivity, we prepared and tested the following E11 mutated MII analogues: MII[E11R] and RDP-MII[E11R]. The binding and functional profiles of the new peptides at native rat ?6?2* receptor were comparable with those of their leads while potency and affinity for native and heterologously expressed ?3?2* nAChRs were reduced. Consequently, MII[E11R] and RDP-MII[E11R] are potent and ?6?2* vs. ?3?2* selective antagonists.

description: Purpose: High-risk Human Papillomavirus (HPV) is the most important cause of cervical cancer. The highest burden of disease is seen in Low-and Low-Middle-Income Countries (LMIC). Several new HPV screening assays have been developed for high-risk HPV (hr-HPV) testing. We compared the performance and adequacy of three HPV genotyping assays on samples from a population of rural women in south-central Ethiopia. Patients and Methods: One hundred and ten cervical swabs from rural women screened for HPV were assayed. HPV DNA was tested using MPG-Luminex Assay, Anyplex II HPV HR Detection, and EUROArray HPV. MPG-Luminex Assay was used as a reference method to compute the sensitivity and specificity of the two commercial assays in detecting hr-HPV infections. Results: Of the 110 samples, MPG-Luminex Assay found 18.2% positive for the 14 hr-HPV and 7.3% for the probable hr-HPV genotypes. AnyplexTM II HPV HR Detection assay and EUROArray HPV Assay identified 21.82% and 12.7% samples, respectively, for the 14 hr-HPVs and both 7.3% for the probable hr-HPV genotypes (Kappa=0.734). Among the 14 hr-HPV genotypes, the genotype -specific agreement of the three HPV genotyping assays was moderate or better for HPV16, 31, 35, 39, 52, 56, 66 and 68. The aggregated sensitivity in detecting the 14 hr-HPV infections of AnyplexTM II HPV HR Detection and EUROArray HPV assays was high, 100% and 70%, respectively. The specificities of AnyplexTM II HPV HR Detection and EUROArray HPV were 95.6% and 100%, respectively. Conclusion: The three evaluated assays showed similar analytical performance in the detection of hr-HPV infections and moderate or better concordance in HPV genotyping. This study is part of the ongoing cluster-randomized trial that has been registered in clinicaltrials.gov (NCT03281135) on September 13, 2017.

Focus marking in Kuria
Creators: name: Landman, Meredith
name: Ranero, Rodrigo
Publisher: name: Zenodo
Year: 2018

description: This paper examines focus marking in Kuria. We propose an account of the syntax/semantics
 of the prefix /ne-/. This prefix displays a varied syntactic distribution, posing a puzzle as to
 what semantically unifies all of its uses. In focus constructions, /ne-/ obligatorily appears
 on a fronted (i.e. focused) phrase, whereas in simple declaratives, /ne-/ obligatorily appears
 pre-verbally. Following previous analyses of similar markers in Bantu (Schwarz 2007 for
 Kikuyu and Abels & Muriungi 2008 for Kiitharaka), we analyze /ne-/ uniformly as a focus
 marker that arises in a focus phrase in the left periphery. We support this account of /ne-
 / by presenting novel data that suggest that even when /ne-/ occurs pre-verbally, it still
 marks focus (VP focus or sentential focus.) We also show how /ne-/ differs syntactically
 from similar markers in other languages. For example, Kuria allows for the focus marker to
 appear internal to the focused constituent, in contrast with data from Kiitharaka (Abels &
 Muriungi 2008) and other languages (see Hartmann & Zimmermann 2009 for Guruntum).
 This paper thus discusses a range of data patterns relating to the Kuria prefix /ne-/, offering
 insight into a syntax/semantic puzzle as well as cross-linguistic variation in the realization
 of focus.
Temporal remoteness and vagueness in past time reference in Luganda

description: In this paper, we point out that past time operators (PTOs) in Luganda, a language that
 makes three past time remoteness distinctions, are vague and context-dependent, and pro-

 adjectives. We call the relevant PTOs RECENT, INTERMEDIATE, and DISTANT, respec-
 tively. Luganda PTOs give rise to borderline cases, where it is difficult to decide whether a
 past reference time (RT) counts as ‘recent’, ‘intermediate’ or ‘distant’. What counts as ‘re-
 cent’, ‘intermediate’ or ‘distant’ is context dependent; e.g., there are contexts where REC is
 acceptable with an RT of a few weeks ago, and contexts where DIST is acceptable for an
 RT of a few minutes ago. We assume that like tenses in English, PTOs in matrix clauses in
 Luganda restrict the relation between utterance time (UT) and RT. However, while English
 past tense presupposes that RT precedes UT (e.g. Kratzer 1998), Luganda PTOs additionally
 encode as part of their meaning a vague, context-dependent measure function that compares
 the length of a time interval to a contextual standard.

description: The dynamicity of functional (curve) markers from modern clinical studies offers deeper insights into complex disease physiology. A frequent clinical practice is to examine various ‘pharmacokinetic features’ of functional markers (definite integral, maximum value, time to maximum, etc.) that reflect important physiological underpinnings. For instance, the current diagnostic procedure for kidney obstruction is to examine several pharmacokinetic features of renogram curves characterizing renal function. Motivated by such clinical practices, we develop a statistical framework for evaluating diagnostic accuracy of pharmacokinetic features using area under the receiver operating characteristic curve (AUC). The major challenge is that functional markers are observed at discrete time points with measurement error. To address this challenge, we develop a two-stage non-parametric AUC estimator based on summary functionals providing unified representation of various pharmacokinetic features and study its asymptotic properties. We also propose a sensible adaptation of a semiparametric regression model that can describe heterogeneity of AUC across different subpopulations, while appropriately handling discreteness and noise in observed functional markers. Here, a novel data-driven approach that balances between bias and efficiency of the regression coefficient estimates is introduced. Finally, the framework is applied to rigorously evaluate pharmacokinetic features of renogram curves potentially useful for detecting kidney obstruction.
Structural transfer in third language acquisition: The case of Lingala-French speakers acquiring English
Creators: name: Philothé Mwamba Kabasele
Publisher: name: Zenodo
Year: 2018

description: This paper tests the claims of Cumulative Enhancement Model, the ‘l2 status factor’, and the
 Typological Primacy Model in investigating how l1 Lingala, l2 French speakers express in
 English an event which took place and was completed in the past. The linguistic phenomena
 understudy informs us that English uses the simple past in a past-completed event while
 French and Lingala use the ‘passé composé’ and the remote or recent past, respectively. The
 study circumscribes the tense similarities and differences between the three languages.
 The paper strives to answer the questions on which previously acquired language between
 the l1, l2, or both l1 & l2 overrides in l3 syntactic transfer. The paper aims to determine
 whether the l2 is the privileged source of syntactic transfer even when the l1 offers syn-
 tactic similarities with the l3. Finally, the study purports to determine whether subjects are
 more accurate when communicating in explicit mode than in implicit mode. That is, the
 study further aims to investigate whether subjects make less transfer errors in a task that
 promotes reliance on explicit knowledge than they do in task that promotes reliance on
 implicit knowledge.
 The findings of the study show that subjects used the simple past tense in the context of a
 past-completed event. The use of the simple past tense in the context of a past-completed
 event might be attributed to transfer from the l1 or might be considered as a consequence
 of positive learning.
 The results further show that subjects have transferred more explicit knowledge than im-
 plicit. And the results have ruled out the l2-status factor claim that the l2 is the privileged
 source of transfer in l3 acquisition.
High spectral resolution spectroscopy of the SiO fundamental lines in red giants and red supergiants with VLT/VISIR

description: We present high spectral resolution (R = 30000) spectroscopic observations of the SiO fundamental lines near 8.1 micron in 16 bright red giants and red supergiants using VLT/VISIR. Our sample consists of seven normal K--M giants, three Mira stars, three optically bright red supergiants, two dusty red supergiants, and the enigmatic object GCIRS3 near the Galactic center. We detected SiO fundamental lines in all of our program stars except for GCIRS3. The SiO lines in normal K and M giants as well as optically bright red supergiants do not show P-Cyg profiles or blueshifts, which means the absence of systematic outflows in the SiO line forming region. On the other hand, we detected P-Cyg profiles in the SiO lines in the dusty red supergiants VY CMa and VX Sgr (with the latter being a new detection), which suggest outflow velocities of 27 and 17 km/s, respectively. We derived basic stellar parameters (effective temperature, surface gravity, luminosity, and mass) for the normal K--M giants and optically bright red supergiants in our sample and compared the observed VISIR spectra with synthetic spectra predicted from MARCS photospheric models. Most of the SiO lines observed in the program stars warmer than ~3400 K are reasonably reproduced by the MARCS models, which allowed us to estimate the silicon abundance as well as the 28Si/29Si and 28Si/30Si ratios. However, we detected possible absorption excess in some SiO lines. Moreover, the SiO lines in the cooler red giants and red supergiant cannot be explained by the MARCS models at all even if the dust emission is taken into account. This disagreement may be a signature of the dense, extended molecular outer atmosphere.

Adjectives in Lubukusu
Creators: name: Aggrey Wasike
Publisher: name: Zenodo
Year: 2018

description: The lexical category of adjectives is proposed to be universal, but its realization varies across languages. In languages such as English, there is a clearly distinct category of adjectives. But in other languages the category of adjectives is not entirely distinct morphologically and syntactically from nouns and verbs. In this paper I show that there is a striking resemblance between adjectives and nouns in Lubukusu. In addition, stage-level predicate meanings are expressed by use of verbs rather than adjectives. Because of these facts, it is tempting to adopt an analysis that reduces Lubukusu adjectives to either nouns or verbs. However, I argue that there is not sufficient evidence to support such an analysis. Lubukusu has true adjectives in spite of the associated nominal and verbal characteristics. A verbal characteristic such as expressing adjectival meanings by use verbs is similar to languages such Mohawk and Vaeakau-Taumako. But there are significant differences between these languages and Lubukusu with regards to this verbal characteristic.

description: This article addresses the problem of identifying the maximum tolerated dose (MTD) in Phase I dose-finding clinical trials with late-onset toxicities. The main design challenge is how best to adaptively allocate study participants to tolerable doses when the evaluation window for the toxicity endpoint is long relative to the accrual rate of new participants. We propose a new design framework based on order-restricted statistical inference that addresses this challenge in sequential dose assignments. We illustrate the proposed method on real data from a Phase I trial of bortezomib in lymphoma patients and apply it to a Phase I trial of radiotherapy in prostate cancer patients. We conduct extensive simulation studies to compare our design’s operating characteristics to existing published methods. Overall, our proposed design demonstrates good performance relative to existing methods in allocating participants at and around the MTD during the study and accurately recommending the MTD at the study conclusion.
Theory of metallic double perovskites with spin orbit coupling and strong correlations; application to ferrimagnetic Ba2FeReO6

description: We consider a model of the double perovskite Ba2FeReO6, a room temperature ferrimagnet with correlated and spin-orbit coupled Re t2g electrons moving in the background of Fe moments stabilized by Hund's coupling. We show that for such 3d/5d double perovskites, strong correlations on the 5d-element (Re) are essential in driving a half-metallic ground state. Incorporating both strong spin-orbit coupling and the Hubbard repulsion on Re leads to a band structure consistent with ab initio calculations. Using our model, we find a large spin polarization at the Fermi level, and obtain a semi-quantitative understanding of the saturation magnetization of Ba2FeReO6, as well as X-ray magnetic circular dichroism data indicating a significant orbital magnetization. Based on the orbital populations obtained in our theory, we predict a specific doping dependence to the tetragonal distortion accompanying ferrimagnetic order. Finally, the combination of a net magnetization and spin-orbit interactions is shown to induce Weyl nodes in the band structure, and we predict a significant intrinsic anomalous Hall effect in hole-doped Ba2FeReO6. The uncovered interplay of strong correlations and spin-orbit coupling lends partial support to our previous work, which used a local moment description to capture the spin wave dispersion found in neutron scattering measurements. Our work is of broad interest for understanding metallic 4d-based and 5d-based double perovskites which are of fundamental interest and of possible relevance to spintronic applications.

description: The Weibull distribution is applied to the number of days between the start date of drug administration and the date of occurrence of an adverse event. The tendency of occurrence of adverse events can be clarified by estimating the two- or three-parameter Weibull distribution, using the data regarding the number of days. Our purpose is to estimate the parameters of the Weibull distribution with high accuracy, even in low-reported adverse events, such as new drugs, polypharmacy and small clinical trials. Furthermore, the two-sample Kolmogorov – Smirnov test (two-sided) is used to examine whether the tendency of occurrence of adverse events is different for two Weibull distributions estimated from two drugs with similar efficacy. We used discrete data derived from FDA Adverse Event Reporting System (FAERS), as the FAERS data are presented in years, months and days without hours and minutes. Because this study focuses on early onset adverse events, data may be contained 0 days. The discreteness of the data and the fact that it may include zero make this distribution different from the general Weibull distribution, which is defined for continuous data greater than zero. We search for the optimal parameter estimation method for the Weibull distribution under these two conditions, and verify its effectiveness using Monte Carlo simulations and FAERS data. Because the results obtained from FAERS data may differ depending on data handling, we describe the of data handling technique and the sample code that can reproduce the results.
Hard X-ray emission cutoff in anomalous X-ray pulsar 4U 0142+61 detected by INTEGRAL

description: The anomalous X-ray pulsar 4U 0142+61 was studied by the INTEGRAL observations. The hard X-ray spectrum of 18 -- 500 keV for 4U 0142+61 was derived using near 9 years of INTEGRAL/IBIS data. We obtained the average hard X-ray spectrum of 4U 0142+61 with all available data. The spectrum of 4U 0142+61 can be fitted with a power-law with an exponential high energy cutoff. This average spectrum is well fitted with a power-law of $Γ\sim 0.51\pm 0.11$ plus a cutoff energy at $128.6\pm 17.2$ keV. The hard X-ray flux of the source from 20 -- 150 keV showed no significant variations (within 20$\%$) from 2003 -- 2011. The spectral profiles have some variability in nine years: photon index varied from 0.3 -- 1.5, and cutoff energies of 110 -- 250 keV. The detection of the high energy cutoff around 130 keV shows some constraints on the radiation mechanisms of magnetars and possibly probes the differences between magnetar and accretion models for these special class of neutron stars. Future HXMT observations could provide stronger constraints on the hard X-ray spectral properties of this source and other magnetar candidates.

Recent results of high-energy spin phenomena of gluons and sea-quarks in polarized proton-proton collisions at RHIC at BNL

description: The STAR experiment at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory is carrying out a spin physics program in high-energy polarized proton collisions at $\sqrt{s}=200\,$GeV and $\sqrt{s}=500\,$GeV to gain a deeper insight into the spin structure and dynamics of the proton. One of the main objectives of the spin physics program at RHIC is the precise determination of the polarized gluon distribution function. The STAR detector is well suited for the reconstruction of various final states involving jets, $π^{0}$, $π^{\pm}$, e$^{\pm}$ and $γ$, which allows to measure several different processes. Recent results suggest a gluon spin contribution to the proton spin at the same level as the quark spin contribution itself. The production of $W$ bosons in polarized p+p collisions at $\sqrt{s}=500\,$GeV opens a new era in the study of the spin-flavor structure of the proton. $W^{-(+)}$ bosons are produced in $\bar{u}+d\;(\bar{d}+u)$ collisions and can be detected through their leptonic decays, $e^{-}+\barν_{e}\;(e^{+}+ν_{e})$, where only the respective charged lepton is measured. Results of $W^{-(+)}$ production suggest a large asymmetry between the polarization of anti-$u$ and anti-$d$ quarks.

Factive relative clauses in Pulaar
Creators: name: Ibrahima Ba
Publisher: name: Zenodo
Year: 2018

description: Drawing from Kayne (1994a), this chapter shows that Headed Relative Clauses and Factive
 Clauses in Pulaar are built from similar structures. Both display word order similarities, and
 in each case the complementizer, which is homophonous with the determiner, agrees with
 the (null or overt) head NP in Spec,CP. The verb form is also the same in Headed Relatives
 and Factive Relatives, and it undergoes the same agreement pattern. Furthermore, Headed
 Relatives and Factives in Pulaar both exhibit island constraints such that extraction out of
 either construction is impossible; this indicates that they all involve movement of some sort.
 The difference between these constructions is that the Headed Relative has an overt head
 noun whereas Factives have null head nouns.
