description: Mirror symmetry, a three dimensional $\mathcal{N}=4$ IR duality, has been studied in detail for quiver gauge theories of the $ADE$-type (as well as their affine versions) with unitary gauge groups. The $A$-type quivers (also known as linear quivers) and the associated mirror dualities have a particularly simple realization in terms of a Type IIB system of D3-D5-NS5-branes. In this paper, we present a systematic field theory prescription for constructing 3d mirror pairs beyond the $ADE$ quiver gauge theories, starting from a dual pair of $A$-type quivers with unitary gauge groups. The construction involves a certain generalization of the $S$ and the $T$ operations, which arise in the context of the $SL(2,\mathbb{Z})$ action on a 3d CFT with a $U(1)$ 0-form global symmetry. We implement this construction in terms of two supersymmetric observables -- the round sphere partition function and the superconformal index on $S^2 \times S^1$. We discuss explicit examples of various (non-$ADE$) infinite families of mirror pairs that can be obtained in this fashion. In addition, we use the above construction to conjecture explicit 3d $\mathcal{N}=4$ Lagrangians for 3d SCFTs, which arise in the deep IR limit of certain Argyres-Douglas theories compactified on a circle.

description: Τα συστήματα προσδιορισμού θρεπτικών ουσιών στοχεύουν στην τοποθέτηση των τροφίμων μεταξύ τους ανάλογα με τη συμβολή τους σε μια ισορροπημένη διατροφή. Η ακρίβεια και η απόδοση των μεθοδολογιών είναι ακόμα υπό συζήτηση. Παρουσιάζουμε εδώ μια κριτική ανάλυση της δομής και της αποτελεσματικότητας των υφιστάμενων σχημάτων. Μέθοδοι: Η έρευνα της βιβλιογραφίας ανίχνευσε μόνο τέσσερα συστήματα που αντιμετωπίζουν το ζήτημα με μια προσέγγιση «σε γενικές γραμμές» και με αρκετή λεπτομέρεια για να καταστεί δυνατή η ανάλυση. Συγκρίθηκαν οι αρχές κατασκευής αυτών των συστημάτων και εκτιμήθηκε η απόδοσή τους μέσω της ταξινόμησή τους σε μια σειρά από 125 τρόφιμα με βάση τη διατροφική σύνθεση. Αυτές οι ταξινομήσεις συγκρίθηκαν μεταξύ τους και με μια εμπειρική ταξινόμηση από ειδικούς διατροφολόγους. Αποτελέσματα: Όλα τα συστήματα έδωσαν παρόμοια επισκόπηση, με τα φρούτα και τα λαχανικά να κατατάσσονται ως τα πιο ευνοϊκά τρόφιμα και τα λιπαρά και ζαχαρούχα τρόφιμα ως τα λιγότερο ευνοϊκά, αλλά υπήρχαν πολυάριθμες αποκλίσεις σε κάθε σύστημα, που σχετίζονται κυρίως με την επιλογή των θρεπτικών συστατικών και των κατωφλίων. Το σύστημα βαθμολόγησης της FA φαινόταν η πιο συνεπής προσέγγιση, αν και εξακολουθούσε να δημιουργεί ορισμένες αμφισβητούμενες βαθμολογίες. Η ταξινόμηση των ειδικών δεν επικύρωσε με σαφήνεια κανένα σχήμα και δεν μπορεί να θεωρηθεί ως αληθινή αναφορά. Συμπέρασμα: Τα συστήματα προσδιορισμού θρεπτικών συστατικών έχουν επιβεβαιωθεί ότι είναι ισχυρά εργαλεία για τη μετάφραση διατροφικών πληροφοριών που σχετίζονται με ολόκληρη τη δίαιτα στο επίπεδο των μεμονωμένων τροφίμων. Ωστόσο, η απόδοση των υφιστάμενων συστημάτων παραμένει μέτρια. Εναλλακτικές προσεγγίσεις, όπως η εξέταση κατηγοριών τροφίμων ή η εισαγωγή αυστηρότερων βημάτων επικύρωσης από μια ομάδα ειδικών διατροφολόγων, θα μπορούσαν να είναι τρόποι για την επίτευξη πιο αποτελεσματικών και συναινετικών εργαλείων.

description: Vector-borne pathogens are inoculated in the skin of mammals, most likely in the dermis. Despite this, subcutaneous (s.c.) models of infection are broadly used in many fields, including Yersinia pestis pathogenesis. We expand on a previous report where we implemented intradermal (i.d.) inoculations to study bacterial dissemination during bubonic plague and compare this model with an s.c. model. We found that i.d. inoculations result in faster kinetics of infection and that bacterial dose influenced mouse survival after i.d. but not s.c. inoculation. Moreover, a deletion mutant of rovA , previously shown to be moderately attenuated in the s.c. model, was severely attenuated in the i.d. model. Lastly, based on previous observations where a population bottleneck from the skin to lymph nodes was observed after i.d., but not after s.c., inoculations, we used the latter model as a strategy to identify an additional bottleneck in bacterial dissemination from lymph nodes to the bloodstream. Our data indicate that the more biologically relevant i.d. model of bubonic plague differs significantly from the s.c. model in multiple aspects of infection. These findings reveal adaptations of Y. pestis to the dermis and how these adaptations can define the progression of disease. They also emphasize the importance of using a relevant route of infection when addressing host-pathogen interactions.

description: Microbial protease-mediated disruption of the intestinal epithelium is a potential mechanism whereby a dysbiotic enteric microbiota can lead to disease. This mechanism was investigated using the colitogenic, protease-secreting enteric microbe Enterococcus faecalis . Caco-2 and T-84 epithelial cell monolayers and the mouse colonic epithelium were exposed to concentrated conditioned media (CCM) from E. faecalis V583 and E. faecalis lacking the gelatinase gene ( gelE ). The flux of fluorescein isothiocyanate (FITC)-labeled dextran across monolayers or the mouse epithelium following exposure to CCM from parental or mutant E. faecalis strains indicated paracellular permeability. A protease-activated receptor 2 (PAR2) antagonist and PAR2-deficient (PAR2 −/− ) mice were used to investigate the role of this receptor in E. faecalis -induced permeability. Gelatinase (GelE) purified from E. faecalis V583 was used to confirm the ability of this protease to induce epithelial cell permeability and activate PAR2. The protease-mediated permeability of colonic epithelia from wild-type (WT) and PAR2 −/− mice by fecal supernatants from ulcerative colitis patients was assessed. Secreted E. faecalis proteins induced permeability in epithelial cell monolayers, which was reduced in the absence of gelE or by blocking PAR2 activity. Secreted E. faecalis proteins induced permeability in the colonic epithelia of WT mice that was absent in tissues from PAR2 −/− mice. Purified GelE confirmed the ability of this protease to induce epithelial cell permeability via PAR2 activation. Fecal supernatants from ulcerative colitis patients induced permeability in the colonic epithelia of WT mice that was reduced in tissues from PAR2 −/− mice. Our investigations demonstrate that GelE from E. faecalis can regulate enteric epithelial permeability via PAR2.

description: Interferon (IFN)-inducible guanylate binding proteins (GBPs) mediate cell-autonomous host resistance to bacterial pathogens and promote inflammasome activation. The prevailing model postulates that these two GBP-controlled activities are directly linked through GBP-dependent vacuolar lysis. It was proposed that the rupture of pathogen-containing vacuoles (PVs) by GBPs destroyed the microbial refuge and simultaneously contaminated the host cell cytosol with microbial activators of inflammasomes. Here, we demonstrate that GBP-mediated host resistance and GBP-mediated inflammatory responses can be uncoupled. We show that PVs formed by the rodent pathogen Chlamydia muridarum , so-called inclusions, remain free of GBPs and that C. muridarum is impervious to GBP-mediated restrictions on bacterial growth. Although GBPs neither bind to C. muridarum inclusions nor restrict C. muridarum growth, we find that GBPs promote inflammasome activation in C. muridarum- infected macrophages. We demonstrate that C. muridarum infections induce GBP-dependent pyroptosis through both caspase-11-dependent noncanonical and caspase-1-dependent canonical inflammasomes. Among canonical inflammasomes, we find that C. muridarum and the human pathogen Chlamydia trachomatis activate not only NLRP3 but also AIM2. Our data show that GBPs support fast-kinetics processing and secretion of interleukin-1β (IL-1β) and IL-18 by the NLRP3 inflammasome but are dispensable for the secretion of the same cytokines at later times postinfection. Because IFN-γ fails to induce IL-1β transcription, GBP-dependent fast-kinetics inflammasome activation can drive the preferential processing of constitutively expressed IL-18 in IFN-γ-primed macrophages in the absence of prior Toll-like receptor stimulation. Together, our results reveal that GBPs control the kinetics of inflammasome activation and thereby shape macrophage responses to Chlamydia infections.

description: In this paper, we propose a novel task, Manipulation Question Answering (MQA), where the robot performs manipulation actions to change the environment in order to answer a given question. To solve this problem, a framework consisting of a QA module and a manipulation module is proposed. For the QA module, we adopt the method for the Visual Question Answering (VQA) task. For the manipulation module, a Deep Q Network (DQN) model is designed to generate manipulation actions for the robot to interact with the environment. We consider the situation where the robot continuously manipulating objects inside a bin until the answer to the question is found. Besides, a novel dataset that contains a variety of object models, scenarios and corresponding question-answer pairs is established in a simulation environment. Extensive experiments have been conducted to validate the effectiveness of the proposed framework.

description:  For a firm or company to survive, grow and compete, it is very essential that marketer identifies the needs and wants of customers and offer products according to their needs more effectively and efficiently than other competitors. Though similar but consumers are unique in themselves due to having different needs and wants which are varied and diversified from one another; and even they have different consumption pattern and consumption behaviour. The marketer helps them in satisfying their needs and wants through offering different products and services. A comprehensive knowledge of consumers and their consumption behaviour is essential for a firm to fight and to succeed.

description: Amyotrophic lateral sclerosis (ALS) is a progressive muscle wasting disorder, characterized by the degeneration of upper and lower motor neurons. There is currently no cure and the disease is fatal 3-5 years post symptom onset. An improved understanding of ALS at the cellular and molecular levels are essential in order to identify disease pathways, leading to motor dysfunction. Zebrafish (Danio rerio) are powerful model organisms in scientific research and have great potential for use in high-throughput drug screening and in the analysis of cellular and molecular mechanisms of disease in vivo and in real-time, as well as possible resulting musculoskeletal phenotypes. The DNA/RNA binding protein, Transactive Response DNA-binding protein 43kDa (TDP-43) is a component of ubiquitinated cytoplasmic inclusions, present in around 97% of ALS cases. A number of causative mutations in the TARDBP gene have been identified in both familial and sporadic ALS patients. This thesis will study the transient and transgenic expression of TDP-43 in zebrafish. The initial investigation of mRNA overexpression gave us rationale to pursue the development of stable transgenic zebrafish specifically expressing the zebrafish ortholog Tdp-43 in motor neurons. In this study, overexpression (OE) of a mutant Tdp-43 construct in a conserved residue associated with sporadic ALS, Q331K, Tg (-3mnx: mVenus: Tdp-43 Q331K), was compared to OE of wild-type (wt) Tdp-43 Tg (-3mnx: mVenus: Tdp-43 wt) and non-transgenic (nTg) controls. We conducted cellular and molecular analysis of these transient and transgenic zebrafish, assessing the localization of Tdp-43 in motor neurons, as well as examining motor phenotypes at larval and adult stages. Our results show Tdp-43 mislocalization in the motor neurons of larvae expressing mVenus: Tdp-43 bearing the conserved point mutation Q331K. This mislocalization is increased on induction of cellular stress, accompanied byreduced locomotion. We also identified progressive degeneration in adult transgenic fish, abnormal neuromuscular junction (NMJ) integrity, decreased swimming ability and reduced survival, compared to nTg and mVenus: Tdp-43wt OE controls. This thesis presents a larval and adult model of ALS, recapitulating multiple facets of disease. Further elucidating the links between the observed cellular dysfunction and motor phenotypes may better our understanding of ALS and take a step toward unveiling the complex neurobiology underlying the disease.

description: Francisella tularensis is a highly virulent Gram-negative intracellular pathogen capable of infecting a vast diversity of hosts, ranging from amoebae to humans. A hallmark of F. tularensis virulence is its ability to quickly grow to high densities within a diverse set of host cells, including, but not limited to, macrophages and epithelial cells. We developed a luminescence reporter system to facilitate a large-scale transposon mutagenesis screen to identify genes required for growth in macrophage and epithelial cell lines. We screened 7,454 individual mutants, 269 of which exhibited reduced intracellular growth. Transposon insertions in the 269 growth-defective strains mapped to 68 different genes. FTT_0924 , a gene of unknown function but highly conserved among Francisella species, was identified in this screen to be defective for intracellular growth within both macrophage and epithelial cell lines. FTT_0924 was required for full Schu S4 virulence in a murine pulmonary infection model. The Δ FTT_0924 mutant bacterial membrane is permeable when replicating in hypotonic solution and within macrophages, resulting in strongly reduced viability. The permeability and reduced viability were rescued when the mutant was grown in a hypertonic solution, indicating that FTT_0924 is required for resisting osmotic stress. The Δ FTT_0924 mutant was also significantly more sensitive to β-lactam antibiotics than Schu S4. Taken together, the data strongly suggest that FTT_0924 is required for maintaining peptidoglycan integrity and virulence.

description: Accurate forecasts of macroeconomic variables are crucial inputs into the decisions of economic agents and policy makers. Exploiting inherent aggregation structures of such variables, we apply forecast reconciliation methods to generate forecasts that are coherent with the aggregation constraints. We generate both point and probabilistic forecasts for the first time in the macroeconomic setting. Using Australian GDP we show that forecast reconciliation not only returns coherent forecasts but also improves the overall forecast accuracy in both point and probabilistic frameworks.

description: We propose two new nonparametric predictive models: the multi-step nonparametric predictive regression model and the multi-step additive predictive regression model, in which the predictive variables are locally stationary time series. We define estimation methods and establish the large sample properties of these methods in the short horizon and the long horizon case. We apply our methods to stock return prediction using a number of standard predictors such as dividend yield. The empirical results show that all of these models can substantially outperform the traditional linear predictive regression model in terms of both in-sample and out-of-sample performance. In addition, we find that these models can always beat the historical mean model in terms of in-sample fitting, and also for some cases in terms of the out-of-sample forecasting. We also propose a trading strategy based on our methodology and show that it beats the buy and hold stategy provided the tuning parameters are well chosen.

description: Background. Coagulase-negative staphylococci (CoNS) are the most commonly isolated pathogens in the neonatal intensive care unit (NICU). CoNS infections are associated with increased morbidity, including neurodevelopmental impairment. Objective. To describe the epidemiology of CoNS infections in the NICU. To determine mortality among infants with definite, probable, or possible CoNS infections. Methods. We performed a retrospective cohort study of all blood, urine, and cerebrospinal fluid cultures from samples obtained from infants aged <121 postnatal days. Setting. A total of 248 NICUs managed by the Pediatrix Medical Group from 1997 to 2009. Results. We identified 16,629 infants with 17,624 episodes of CoNS infection: 1,734 (10%) definite, 3,093 (17%) probable, and 12,797 (73%) possible infections. Infants with a lower gestational age and birth weight had a higher incidence of CoNS infection. When controlling for gestational age, birth weight, and 5-minute Apgar score, we found that infants with definite, probable, or possible CoNS infection had lower mortality (odds ratio [OR], 0.74 [95% confidence interval {CI}: 0.61, 0.89], 0.68 [95% CI, 0.59, 0.79], and 0.69 [95% CI, 0.63, 0.76], respectively) compared with infants who had negative culture results ( P <.001). No significant difference in overall mortality was found in infants who had definite CoNS infection compared with those who had probable or possible CoNS infection (OR, 0.93 [95% CI, 0.75, 1.16] and 0.85 [95% CI, 0.70, 1.03], respectively). Conclusions. CoNS infection was strongly related to lower gestational age and birth weight. Infants with clinical sepsis and culture-positive CoNS infection had lower mortality rates than infants with clinical sepsis and negative blood culture results. No difference in mortality between infants with a diagnosis of definite, probable, or possible CoNS infection was observed.

description: Making use of the information from the World Value Survey (WVS), and operationalizing a definition of national culture that encompasses both the relevance of specific cultural traits and the interdependence among them, this paper proposes a methodology to reveal the latent structure of national culture and to measure cultural distance between countries that takes into account both the difference in cultural traits and the difference in the network structure of national cultures. Exploiting the possibilities offered by copula graphical models for discrete data, this paper infers the cultural networks of all the countries included in the WVS (Wave 6) and proposes a novel unifying framework to measure national culture and international cultural distances. The Jeffreys' divergence between copula graphical models, taken as the measure of cultural distance between countries, captures the orthogonality of the two components of cultural distance: the one based on cultural traits and the one based on the network structure among them. Moreover, the two components are shown to correlate with different national and structural characteristics of cultural networks, thus encompassing the different informational sets related to national cultures.

description: Objective. To identify patient-care practices related to an increased prevalence of hepatitis C virus (HCV) infection among chronic hemodialysis patients. Design. Survey. Setting. Chronic hemodialysis facilities in the United States. Participants. Equal-probability 2-stage cluster sampling was used to select 87 facilities from all Medicare-approved providers treating 30–150 patients; 53 facilities and 2,933 of 3,680 eligible patients agreed to participate. Methods. Patients were tested for HCV antibody and HCV RNA. Data on patient-care practices were collected using direct observation. Results. The overall prevalence of HCV infection was 9.9% (95% confidence interval [CI], 8.2%–11.6%); only 2 of 294 HCV-positive patients were detected solely by HCV RNA testing. After adjusting for non-dialysis-related HCV risk factors, patient-care practices independently associated with a higher prevalence of HCV infection included reusing priming receptacles without disinfection (odds ratio [OR], 2.3 [95% CI, 1.4–3.9]), handling blood specimens adjacent to medications and clean supplies (OR, 2.2 [95% CI, 1.3–3.6]), and using mobile carts to deliver injectable medications (OR, 1.7 [95% CI, 1.0–2.8]). Independently related facility covariates were at least 10% patient HCV infection prevalence (OR, 3.0 [95% CI, 1.8–5.2]), patient-to-staff ratio of at least 7: 1 (OR, 2.4 [95% CI, 1.4–4.1]), and treatment duration of at least 2 years (OR, 2.4 [95% CI, 1.3–4.4]). Conclusions. This study provides the first epidemiologic evidence of associations between specific patient-care practices and higher HCV infection prevalence among hemodialysis patients. Staff should review practices to ensure that hemodialysis-specific infection control practices are being implemented, especially handling clean and contaminated items in separate areas, reusing items only if disinfected, and prohibiting mobile medication and clean supply carts within treatment areas.

description: We express the beta invariant of a loopless matroid as tropical self-intersection number of the diagonal of its matroid fan (a "local" Poincaré-Hopf theorem). This provides another example of uncovering the "geometry" of matroids by expressing their invariants in terms of tropicalised geometric constructions. We also prove a global Poincaré-Hopf theorem and initiate the study of a more general tropical Lefschetz-Hopf trace formula by proving the two special cases of tropical curves and tropical tori.

Η έρευνα διεξήχθη μέσω ηλεκτρονικού ερωτηματολογίου, που είχε ήδη σχεδιαστεί και χρησιμοποιηθεί (σε έντυπη μορφή) σε αντίστοιχη έρευνα από Ιταλούς ερευνητές. Το ερωτηματολόγιο GeNSK (General and Sport Nutrition Knowledge Questionnaire) είχε ήδη ελεγχθεί σχετικά με την εγκυρότητα και την αξιοπιστία του. Ακολούθησε η μετάφρασή του στα ελληνικά και η συμπλήρωσή τους από τους 80 μαθητές 3 διαφορετικών δημόσιων σχολείων της Αθήνας. Πρέπει να σημειωθεί ότι το δείγμα της έρευνας ήταν περιορισμένο, αφού σκοπός ήταν απλώς μία αρχική αποτύπωση των γενικών τάσεων και όχι αυστηρή στατιστική μελέτη με στόχο τις γενικεύσεις. Με βάση τα ευρήματα σχετικά με τις γνώσεις των μαθητών, σχεδιάστηκε η εκπαιδευτική πρόταση. Πιο συγκεκριμένα σχεδιάστηκε ένα εκπαιδευτικό παιχνίδι με κάρτες γύρω από έννοιες της διατροφής. Σκοπός του ήταν να αποτελέσει μία παιγνιώδη και ψυχαγωγική εκπαιδευτική πρόταση με σαφείς ωστόσο διδακτικούς στόχους. Το παιχνίδι σχεδιάστηκε με αυτόν τον τρόπο έτσι ώστε να διαφοροποιείται από την κλασσική, παραδοσιακή διδασκαλία χωρίς όμως να αποκλίνει από τα προσδοκώμενα μαθησιακά οφέλη. Άλλωστε είναι γνωστό ότι οι γνώσεις γύρω από τη διατροφή συσχετίζονται άμεσα με τις διατροφικές συνήθειες του ανθρώπου άρα και την υγεία του ως έναν σημαντικό βαθμό. Μάλιστα τα αποτελέσματα του ερωτηματολογίου επιβεβαίωσαν τις αναμενόμενες αποσπασματικές γνώσεις ή/και παρανοήσεις που είχαν οι μαθητές και επισφράγισαν την ανάγκη εύρεσης διδακτικών προσεγγίσεων ώστε να ενισχυθούν οι εν λόγω γνώσεις, κυρίως καθώς ακροθιγώς εξετάζονται από τα Αναλυτικά Προγράμματα Σπουδών (ΑΠΣ) διαφορετικών αντικειμένων της ελληνικής υποχρεωτικής εκπαίδευσης. Τέλος, πρέπει να αναφερθεί ότι το εκπαιδευτικό παιχνίδι δεν έχει εφαρμοστεί σε μαθητές ώστε να αξιολογηθούν τα αποτελέσματά του. Αυτό είναι ένα επόμενο βήμα στην έρευνα, που θα μπορούσε να καταδείξει αδυναμίες αλλά και δυνατά σημεία και φυσικά θα μπορούσαν να προταθούν τροποποιήσεις που θα ταίριαζαν ακόμη περισσότερο στα κατά τόπους μαθητικά κοινά και τις ιδιαίτερες διατροφικές (π.χ. τοπικές) συνήθειες.

description: Strain measurement is one of the basic techniques in sheet metal forming for quantifying the deformation of a material under the effects of various loading conditions. The main components in the automatic strain measurement system are the image acquisition hardware and image processing software. This paper presents an automatic single point strain analysis system for sheet metal forming applications. The proposed system is very portable and consists of a USB microscope with different end caps for image acquisition. The software system was developed using Python - OpenCV library and provided with a graphical user interface (GUI).

description: Objective. Acute hepatitis B virus (HBV) infections have been reported in long-term care facilities (LTCFs), primarily associated with infection control breaks during assisted blood glucose monitoring. We investigated HBV outbreaks that occurred in separate skilled nursing facilities (SNFs) to determine factors associated with transmission. Design. Outbreak investigation with case-control studies. Setting. Two SNFs (facilities A and B) in Durham, North Carolina, during 2009–2010. Patients. Residents with acute HBV infection and controls randomly selected from HBV-susceptible residents during the outbreak period. Methods. After initial cases were identified, screening was offered to all residents, with repeat testing 3 months later for HBV-susceptible residents. Molecular testing was performed to assess viral relatedness. Infection control practices were observed. Case-control studies were conducted to evaluate associations between exposures and acute HBV infection in each facility. Results. Six acute HBV cases were identified in each SNF. Viral phylogenetic analysis revealed a high degree of HBV relatedness within, but not between, facilities. No evaluated exposures were significantly associated with acute HBV infection in facility A; those associated with infection in facility B (all odds ratios >20) included injections, hospital or emergency room visits, and daily blood glucose monitoring. Observations revealed absence of trained infection control staff at facility A and suboptimal hand hygiene practices during blood glucose monitoring and insulin injections at facility B. Conclusions. These outbreaks underscore the vulnerability of LTCF residents to acute HBV infection, the importance of surveillance and prompt investigation of incident cases, and the need for improved infection control education to prevent transmission.

description: Ultra-light bosons such as axions or axion-like particles (ALPs), are promising candidates to solve the dark matter problem. A unique way to detect such ALPs is to search for the periodic oscillation feature of the position angles of linearly polarized photons emitted from the regions where ALP dark matter forms a solitonic core. In this work, we use the high-resolution polarimetric measurements of the radiation near the super-massive black hole (SMBH) in the center of the Milky Way, i.e., Sagittarius A$^\star$ (Sgr A$^\star$), by a sub-array of the Event Horizon Telescope to search for the ultra-light ALPs. We derive upper limits on the ALP-photon coupling of $\sim 10^{-12}{\rm GeV^{-1}}$ for ALP masses of $m\sim (10^{-19}-10^{-18})$eV. Our results are stronger than that derived from the observations of SN1987A and a population of supernovae in the mass window of ($10^{-19}-10^{-17}$)eV. Improved polarimetric measurements with the full Event Horizon Telescope can further strengthen the constraints.

description: Objective. To determine the effectiveness of an automated ultraviolet-C (UV-C) emitter against vancomycin-resistant enterococci (VRE), Clostridium difficile , and Acinetobacter spp. in patient rooms. Design. Prospective cohort study. Setting. Two tertiary care hospitals. Participants. Convenience sample of 39 patient rooms from which a patient infected or colonized with 1 of the 3 targeted pathogens had been discharged. Intervention. Environmental sites were cultured before and after use of an automated UV-C-emitting device in targeted rooms but before standard terminal room disinfection by environmental services. Results. In total, 142 samples were obtained from 27 rooms of patients who were colonized or infected with VRE, 77 samples were obtained from 10 rooms of patients with C. difficile infection, and 10 samples were obtained from 2 rooms of patients with infections due to Acinetobacter . Use of an automated UV-C-emitting device led to a significant decrease in the total number of colony-forming units (CFUs) of any type of organism (1.07 log 10 reduction; P < .0001), CFUs of target pathogens (1.35 log 10 reduction; P < .0001), VRE CFUs (1.68 log 10 reduction; P < .0001), and C. difficile CFUs (1.16 log 10 reduction; P < .0001). CFUs of Acinetobacter also decreased (1.71 log 10 reduction), but the trend was not statistically significant P = .25). CFUs were reduced at all 9 of the environmental sites tested. Reductions similarly occurred in direct and indirect line of sight. Conclusions. Our data confirm that automated UV-C-emitting devices can decrease the bioburden of important pathogens in real-world settings such as hospital rooms.

description: We consider flat epimorphisms of commutative rings $R\to U$ such that, for every ideal $I\subset R$ for which $IU=U$, the quotient ring $R/I$ is semilocal of Krull dimension zero. Under these assumptions, we show that the projective dimension of the $R$-module $U$ does not exceed $1$. We also describe the Geigle-Lenzing perpendicular subcategory $U^{\perp_{0,1}}$ in $R\mathsf{-Mod}$. Assuming additionally that the ring $U$ and all the rings $R/I$ are perfect, we show that all flat $R$-modules are $U$-strongly flat. Thus we obtain a generalization of some results of the paper arXiv:1801.04820, where the case of the localization $U=S^{-1}R$ of the ring $R$ at a multiplicative subset $S\subset R$ was considered.

description: Background. Change from nonmolecular to molecular testing techniques is thought to contribute to the increasing trend in incidence of Clostridium difficile infection (CDI); however the degree of effect attributed to this versus other time-related epidemiologic factors is unclear. Methods. We compared the relative change in incidence rate (IRR) of healthcare facility–associated (HCFA) CDI among hospitals in the Duke Infection Control Outreach Network before and after the date of switch from nonmolecular tests to polymerase chain reaction (PCR) using prospectively collected surveillance data from July 2009 to December 2011. Data from 10 hospitals that switched and 22 control hospitals were included. Individual hospital estimates were determined using Poisson regression. We used an interrupted time series approach to develop a Poisson mixed-effects model. Additional regression adjustments were made for clustering and proportion of intensive care unit patient-days. The variable for PCR was treated as a fixed effect; other modeled variables were random effects. Results. For those hospitals that switched to PCR, mean incidence rate of HCFA CDI before the switch was 6.0 CDIs per 10,000 patient-days compared with 9.6 CDIs per 10,000 patient-days after the switch. Estimates of hospital-specific IRR that compared after the switch with before the switch ranged from 0.89 (95% confidence interval [CI], 0.32–2.44) to 6.91 (95% CI, 1.12–42.54). After adjustment in the mixed-effects model, the overall IRR comparing CDI incidence after the switch to before the switch was 1.56 (95% CI, 1.28–1.90). Time-trend variables did not reach statistical significance. Conclusion. Hospitals that switched from nonmolecular to molecular tests experienced an approximate 56% increase in the rate of HCFA CDI after testing change.

description: Empirical growth analysis has three major problems -- variable selection, parameter heterogeneity and cross-sectional dependence -- which are addressed independently from each other in most studies. The purpose of this study is to propose an integrated framework that extends the conventional linear growth regression model to allow for parameter heterogeneity and cross-sectional error dependence, while simultaneously performing variable selection. We also derive the asymptotic properties of the estimator under both low and high dimensions, and furtherinvestigate the finite sample performance of the estimator through Monte Carlo simulations. We apply the framework to a dataset of 89 countries over the period from 1960 to 2014. Our results reveal some cross-country patterns not found in previous studies (e.g., "middle income trap hypothesis", "natural resources curse hypothesis", "religion works via belief, not practice", etc.).
