description: Anderson localization is a general phenomenon that applies to a variety of disordered physical systems. Recently, a novel manifestation of Anderson localization for wave packets launched with a finite average velocity was proposed, the Quantum boomerang effect (QBE). This phenomenon predicts that the disorder-averaged center of mass of a particle initially moves ballistically, then makes a U-turn, and finally slowly returns to its initial position. The QBE has been predicted to take place in several Hermitian models with Anderson localization and has been experimentally observed in the paradigmatic quantum kicked rotor model. In this work, we investigate the emergence of the QBE in non-Hermitian systems and clarify the importance of symmetries of the Hamiltonian and the initial state. We generalize the analytical arguments available in the literature and show that even in the case of complex spectrum a boomerang-like behavior can appear in a non-Hermitian system. We confirm our analytical results through a careful numerical investigation of the dynamics for several non-Hermitian models. We find that non-Hermiticity leads to the breakdown of the dynamical relation, though the QBE is preserved. This work opens up new avenues for future investigations in Anderson localized systems. The models studied here may be implemented using cold atoms in optical lattices.

description: Background: No data are available on clinical manifestations and course of norovirus gastroenteritis (NVE) in intestinal allograft (from intestinal and multivisceral transplant recipients, ITR) compared to native intestine (from other allograft recipients, nITR). Methods: This was a retrospective study of solid organ transplant recipients with NVE at two centers from January 1, 2010 to April 1, 2014. Chi-square, t-test, linear and logistic regression analyses were done to compare NVE in ITR vs nITR patients. Results: The ITR (45 patients) were compared to nITR (107 patients). ITR were younger (odds ratio [OR]=0.90; P<.0001), less likely to receive anti-lymphocyte induction therapy (OR=0.15; P<.0001), and had shorter time from transplant to NVE (OR=0.99; P=.008). On presentation ITR had less frequent nausea (OR=0.11; P<.0001) or vomiting (OR=0.36; P=.01), higher white blood cell count (OR=1.09; P=.001), and higher glomerular filtration rate (OR=1.02; P<.0001). ITR were less likely to receive anti-motility agents (OR=9.6; P<.0001). ITR were more likely to stay longer on intravenous (IV) fluids (OR=1.18; P<.0001); have recurrent NVE (OR=4.25; P<.0001); have longer hospital stay (OR=1.07; P<.0001); develop acute rejection (OR=5.1; P=.006); and have lower overall survival (OR=0.28; P=.006). Conclusions: Compared to nITR, the ITR with NVE were significantly younger, had less nausea and vomiting at presentation, received less anti-motility agents, required more IV fluids, and had longer hospital stay. A trend was seen for lower survival with NVE in ITR.

description: Inverse Compton Scattering (ICS) has gained much attention recently because of its promise for the development of table-top-size X-ray light sources. Precise and fast simulation is an indispensable tool for predicting the radiation property of a given machine design and to optimize its parameters. Instead of the conventional approach to compute radiation spectra which directly evaluates the discretized Fourier integral of the Liénard-Wiechert field given analytically (referred to as the frequency-domain method), this article focuses on an approach where the field is recorded along the observer time on a uniform time grid which is then used to compute the radiation spectra after completion of the simulation, referred to as the time-domain method. Besides the derivation and implementation details of the proposed method, we analyze possible parallelization schemes and compare the parallel performance of the proposed time-domain method with the frequency-domain method. We will characterize scenarios/conditions under which one method is expected to outperform the other.

description: Providing higher data rates in mobile communication systems without increasing bandwidth can be achieved with techniques such as multi-user multiple-inputand multiple-output transmissions using linear precoding. One popular precoding strategy that is often used in practice is zero-forcing precoding, which utilises multiple antennas to cancel the interference between users. The performance of zero-forcing precoding strongly depends on the similarities of the channels of scheduled users. Therefore, a user grouping heuristic is proposed that optimises the transmission in terms of sum-through put. In addition, an extension is introduced to trade-off through put against fairness among users. The proposed algorithm is compared to a semi-orthogonal user selection algorithm by performing system level simulations. The performance of the algorithms is also investigated in a cellular scenario together with fractional frequency reuse.

China's antibiotic resistance problems

Publisher: name: Lancet Publishing Group
Year: 2017

description: In hospitals worldwide, carbapenem resistance in Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa is a major problem because the only options usually left for treatment of carbapenem resistant organisms are toxic and questionably effective— eg, colistin, polymyxin B, tigecycline, or sometimes aminoglycosides. Serious infections with carbapenem-resistant organisms cause substantial mortality. Newer antibiotic options, such as ceftazidime with avibactam or ceftolozane with tazobactam, are available in some countries but are expensive, have not been studied extensively in clinical trials of infections due to carbapenem-resistant organisms, and do not have activity against the broad suite of carbapenem resistance mechanisms. Several other new antibiotics with a broader spectrum of activity, including against carbapenem-resistant Gram-negative bacilli, are in advanced development but are not yet available other than in clinical trials.

Carbapenem-resistant Enterobacteriaceae: What we know and what we need to know
Creators: name: van Duin D.
Publisher: name: Taylor and Francis Inc.
Year: 2017

description: Infections caused by carbapenem-resistant Enterobacteriaceae (CRE) are a significant cause of morbidity and mortality worldwide. CRE are defined by the Centers for Disease Control and Prevention (CDC) as those Enterobacteriaceae that are resistant in vitro to any carbapenem antimicrobial. This means a minimum inhibitory concentration (MIC) of ≥ 2 mg/ml for ertapenem, or an MIC ≥ 4 mg/ml for doripenem, meropenem, or imipenem. In addition, those Enterobacteriaceae that are documented to produce a carbapenemase are also considered CRE, regardless of carbapenem MIC. For Enterobacteriaceae species that have intrinsic imipenem resistance – such as Morganella morganii, Proteus spp. and Providencia spp – resistance to carbapenems other than imipenem is required.2 This phenotypic definition includes both carbapenemase-producing Enterobacteriaceae (CPE or CP-CRE) as well as non-carbapenemase-producing CRE. A retrospective study evaluating the impact of carbapenemase production on outcomes after monomicrobial CRE bloodstream infections (BSI) found that patients infected with CP-CRE were at increased risk of dying within 14 d as compared with patients with non-carbapenemase-producing CRE (adjusted odds ratio, 4.92; 95% confidence interval 1.01–24.81). The authors speculated that increased virulence of CP-CRE rather than patient factors were the cause of this observation.

description: The presence of spacetime singularities in physically relevant solutions of the Einstein Equations is normally interpreted as a symptom of the breakdown of classical general relativity at very high densities/curvatures. However, despite significant efforts in the past decades, we do not have yet any robust theoretical framework to solve the problem of spacetime singularities. In this context, the past few years have seen an increasing interest in the study of phenomenological scenarios to describe singularity-free black holes, gravitational collapses, and cosmological models. In the present work, we consider the recent proposal by Mazza, Franzin & Liberati for a rotating regular black hole and we measure their regularization parameter $l$ from the available X-ray and gravitational wave black hole data. For $l = 0$, we recover the singular Kerr solution of general relativity, while for $l \neq 0$ we can have a regular black hole or a regular wormhole. Our analysis shows that the available data are consistent with a vanishing regularization parameter $l$ and we can constrain its value. From a NuSTAR spectrum of the Galactic black hole in EXO 1846-031, we find $l/M < 0.49$ (90% CL). From the gravitational wave event GW190707A, we find $l/M < 0.72$ (90% CL).

description: Solid organ transplant (SOT) recipients may develop protracted diarrheal illness from norovirus. We performed a retrospective chart review between January 2010 and April 2014 to identify predictors of persistent diarrhea in transplant recipients with norovirus enteritis. A total of 152 SOT recipients with mean age of 31.5 years (SD 23.1) were included: 43.4% male, 34.2% pediatric patients. Allograft types were abdominal 136 (89.5%) (kidney [39.5%], liver-small bowel [23%], other [27%]) and thoracic 16 (10.5%). The median time to diagnosis of first norovirus enteritis episode from date of transplantation was 1.7 (0.3-5.3) years. At time of presentation, diarrhea was present in 141 (93%). Thirty percent had persistent diarrhea at 2 weeks. Hospitalization was required for treatment in 121 (80%) of episodes with the mean length of stay of 10±15.2 days. Most (91%) infections were due to norovirus genogroup II, and gastrointestinal coinfections were seen in 23 (19%) norovirus enteritis episodes. Nausea at time of diagnosis (P=.002) and cytomegalovirus (CMV) infection in the preceding 90 days (P=.036) were identified as independent risk factors for persistent diarrhea using univariate and multivariable logistic regression. Our study shows that nausea on presentation and prior CMV infection were associated with persistent diarrhea in patients with norovirus enteritis.

In particular, we summarise different descriptions of the Forward Mode of AD, like the matrix-vector product based approach, the idea of lifting functions to the algebra of dual numbers, the method of Taylor series expansion on dual numbers and the application of the push-forward operator, and explain why they all reduce to the same actual chain of computations. We further give a short mathematical description of some methods of higher-order Forward AD and, at the end of this paper, briefly describe the Reverse Mode of Automatic Differentiation.

description: Introduction: Reactivation of cytomegalovirus (CMV) infection is a major threat and it causes significant morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). There remains, however, a paucity of evidence regarding the economic burden of current CMV management in Japan. The aim of this study is to characterize the healthcare resource utilization (HCRU) and cost incurred for CMV management post allo-HSCT, using a Japanese hospital claims database. Methods: Patients who underwent allo-HSCT between April 2010 and March 2018 were identified and followed up for 180 days. Results: In total, 916 patients were included for analysis and categorized into CMV (−) group and CMV (+) group based on the presence of a CMV episode within 100 days post allo-HSCT. A CMV episode was defined as evidence of receiving at least one dose of the following anti-CMV drugs, ganciclovir, foscarnet, or valganciclovir. The mean (± standard deviation [SD]) total length of stay was 93.6 (± 43.7) days in the CMV (+) group, which was significantly longer than 55.9 (±40.6) days in the CMV (−) group, and this trend was more pronounced in patients with multiple CMV episodes. The mean (±SD) total medical cost within 180 days post allo-HSCT was US$122,328 (±56,977) in the CMV (+) group, while the mean total medical cost was US$75,344 (±43,821) in the CMV (−) group. Moreover, transfusion and antimicrobial use was observed as the major medication cost component, which is suggestive of the indirect effect of CMV episodes. Conclusion: This study demonstrated that CMV episodes post allo-HSCT were associated with increased HCRU and cost.

description: Gibbons (Hylobatidae) are species highly adapted to tree-top living. Thus, their movement can be compromised due to the negative impact roads have on canopy habitats. In this study, we built two single-rope artificial canopy bridges and a ladder bridge at two out of five locations where a group of white-handed gibbons (Hylobates lar) in Khao Yai National Park, Thailand were known to cross a main park road. We compared road crossing frequencies, home-range characteristics, and other ad libitum observations during the periods before and after bridge installation. After bridge construction was complete, the group took 10 weeks to use the single rope bridges to navigate over the road. During 442 group follow observation hours and 539 bridge observation hours, 131 crosses over the road were observed. The adult female usually crossed the road first, and the group showed a clear preference for the single-rope bridges over the ladder bridge (92 crossings versus 5). Gibbons crossed the road approximately once a day and crossed mostly at the bridge locations both before and after bridge construction. There were not significant changes in crossing rates from before (crossing between the tree branches and on the ground) to after bridge installation at both the places where bridges were installed (crossing using the bridges). Nonetheless, with more crossings being in the bridges than on the ground after bridge installation, crossings were presumably safer. These findings suggest that gibbons will cross a road on the ground, risking predation, encountering people, or being hit by a vehicle, but artificial canopy bridges provided a safer crossing option since gibbons no longer crossed on the road or jumped across wide gaps at the two locations where bridges were constructed. Maintaining canopy connectivity over roads using artificial bridges logically improves home range connectivity, potentially gene flow, and safety of canopy dwellers. However, connecting areas which were not previously connected should be considered carefully. The new connection could disrupt group dynamics, particularly for species that defend territories, such as gibbons.

description: Ge/SiGe multi-quantum well heterostructures are highly sought-after for silicon-integrated optoelectronic devices operating in the broad range of the electromagnetic spectrum covering infrared to terahertz wavelengths. However, the epitaxial growth of these heterostructures at a thickness of a few microns has been a challenging task due the lattice mismatch and its associated instabilities resulting from the formation of growth defects. To elucidates these limits, we outline herein a process for the strain-balanced growth on silicon of 11.1 nm/21.5 nm Ge/Si0.18Ge0.82 superlattices (SLs) with a total thickness of 16 μm corresponding to 500 periods. Composition, thickness, and interface width are preserved across the entire SL heterostructure, which is an indication of limited Si-Ge intermixing. High crystallinity and low defect density are obtained in the Ge/Si0.18Ge0.82 layers, however, the dislocation pile up at the interface with the growth substate induces micrometer-longs cracks on the surface. This eventually leads to significant layer tilt in the strain-balanced SL and in the formation of millimeter-long, free-standing flakes. These results confirm the local uniformity of structural properties and highlight the critical importance of threading dislocations in shaping the wafer-level stability of thick multi-quantum well heterostructures required to implement effective silicon-compatible Ge/SiGe photonic devices.

description: We propose a novel technique to probe shape of a single microbe embedded in a nematic liquid crystal (NLC) sample by observing geometry of dark brushes with optical microscope using a cross-polarizer set up. Assuming certain anchoring conditions for the NLC director at the surface of the microbe, we determine the resulting shapes of brushes using numerical simulations. Our results suggest that for asymmetrical microbes (such as cylindrical shaped bacteria/viruses), resulting brushes may carry the imprints of this asymmetry (e.g. the aspect ratio of cylindrical shape) at relatively large distances to be able to be seen using simple optical microscopy even for microbe sizes in few tens to few hundred nanometer range.

description: Multidrug resistant (MDR) bacteria are one of the most important threats to public health. Typically, MDR bacteria are associated with nosocomial infections. However, some MDR bacteria have become prevalent causes of community-acquired infections. The spread of MDR bacteria into the community is a crucial development, and is associated with increased morbidity, mortality, health care costs, and antibiotic use. Factors associated with community dissemination of MDR bacteria overlap but are distinct from those associated with nosocomial spread. Prevention of further community spread of MDR bacteria is of the utmost importance, and requires a multidisciplinary approach involving all stakeholders.

description: Fluoroquinolone (FQ) antibiotics have been shown to reduce mortality and the number of febrile episodes when used as prophylaxis during neutropenia. Prior studies suggest that prophylaxis may result in increasing rates of FQ resistance. Fluoroquinolone non-susceptibility trends in Escherichia coli isolated from blood and urine cultures were evaluated over a 16-year period during which prophylaxis was initiated in patients with hematologic malignancies and stem cell transplants. Non-susceptibility rates increased after the introduction of prophylaxis, with yearly non-susceptibility rates rising from 30%–33% to 40%–88% in blood isolates. The high rates of non-susceptibility now observed raise concerns about the continued efficacy of FQ prophylaxis. This concern exists particularly in those patients undergoing stem cell transplants where the total FQ non-susceptibility rates over the study period were 82.3%. Further evaluation of the effect of FQ prophylaxis on antibiotic resistance and its efficacy in the setting of increased rates of resistance is warranted.

description: Burn injuries are a common source of morbidity and mortality in the United States, with an estimated 450,000 burn injuries requiring medical treatment, 40,000 requiring hospitalization, and 3,400 deaths from burns annually in the United States. Patients with severe burns are at high risk for local and systemic infections. Furthermore, burn patients are immunosuppressed, as thermal injury results in less phagocytic activity and lymphokine production by macrophages. In recent years, multidrug-resistant (MDR) pathogens have become major contributors to morbidity and mortality in burn patients.

description: It is observed that the infinite matrix with entries $(\sqrt{mn}\log (mn))^{-1}$ for $m, n\ge 2$ appears as the matrix of the integral operator $\mathbf{H}f(s):=\int_{1/2}^{+\infty}f(w)(ζ(w+s)-1)dw$ with respect to the basis $(n^{-s})_{n\ge 2}$; here $ζ(s)$ is the Riemann zeta function and $H$ is defined on the Hilbert space ${\mathcal H}^2_0$ of Dirichlet series vanishing at $+\infty$ and with square-summable coefficients. This infinite matrix defines a multiplicative Hankel operator according to Helson's terminology or, alternatively, it can be viewed as a bona fide (small) Hankel operator on the infinite-dimensional torus ${\Bbb T}^{\infty}$. By analogy with the standard integral representation of the classical Hilbert matrix, this matrix is referred to as the multiplicative Hilbert matrix. It is shown that its norm equals $π$ and that it has a purely continuous spectrum which is the interval $[0,π]$; these results are in agreement with known facts about the classical Hilbert matrix. It is shown that the matrix $(m^{1/p} n^{(p-1)/p}\log (mn))^{-1}$ has norm $π/\sin(π/p)$ when acting on $\ell^p$ for $1

description: Objectives: The discovery of alternative and well-tolerated anti-arthritic drugs, especially from natural products, is becoming an area of active research. Pedunculoside (PE) is a novel triterpene saponin extracted from the dried bark of Ilex rotunda Thunb. Limited published papers have reported its pharmacological properties, including anti-inflammatory, anti-myocardial ischaemia, anti-liver injury, and hypocholesterolaemic activities. However, the effect of PE on rheumatoid arthritis (RA) remains unknown. Here, we investigated the anti-arthritic effect of PE in both in vitro and in vivo models. Method: The inhibitory effects of PE on proliferation, migration, and production of inflammatory mediators in primary fibroblast-like synoviocytes (FLSs) were examined by a 5-ethynyl-2ʹ-deoxyuridine incorporation assay, wound-healing assay, and real-time polymerase chain reaction, respectively. Cellular signalling mechanisms were analysed by Western blot. The in vivo studies were performed using a collagen-induced arthritis (CIA) rat model. Multiple methods, including arthritis scoring, enzyme-linked immunoassay, radiography, and histopathological assessment, were used to evaluate the therapeutic effects of PE on CIA rats. Results: The in vitro studies revealed that PE significantly inhibited proliferation and migration of FLSs. PE also decreased the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-6, IL-8, and tumour necrosis factor-α (TNF-α). Western blot results suggested that PE suppressed TNF-α-stimulated activation of p38 and extracellular signal-regulated kinase. The in vivo studies showed that PE treatment significantly inhibited synovial inflammation and bone destruction in CIA rats. Conclusion: These results demonstrate that PE exerts an inhibitory role in FLSs and CIA rats, and therefore may have therapeutic value for the treatment of RA.

description: We briefly review the research on second sound in ultracold atomic physics, with emphasis on strongly interacting unitary Fermi gases with infinitely large $s$-wave scattering length. Second sound is a smoking-gun feature of superfluidity in any quantum superfluids. The observation and characterization of second sound in ultracold quantum gases has been a long-standing challenge, and in recent years there are rapid developments due to the experimental realization of a uniform box-trap potential. The purpose of this review is to present a brief historical account of the key research activities on second sound over the past two decades. We summarize the initial theoretical works that reveal the characteristics of second sound in a unitary Fermi gas, and introduce its first observation in a highly elongated harmonic trap. We then discuss the most recent measurement on second sound attenuation in a uniform setup, which may open a new era to understand quantum transport near quantum criticality in the strongly interacting regime. The observation of second sound in homogeneous weakly interacting Bose condensates in both two and three dimensions are also briefly introduced.

description: Use of antibiotics among livestock contributes to the selection and dissemination of multidrug resistant (MDR) bacteria. Olaquindox and carbadox are quinoxaline derivatives with antibacterial properties that prevent dysentery and enhance weight gain in suckling pigs. Resistance to quinoxalines is mediated by the efflux pump OqxAB, which also extrudes antibiotics such as chloramphenicol and fluoroquinolones. The gene encoding this efflux pump, oqxAB, was initially detected within plasmid pOLA52, which was found in Escherichia coli isolated from swine manure. Dissemination of oqxAB has been noted in Salmonella species, and the original genetic reservoir of oqxAB was traced to the chromosome of Klebsiella pneumoniae. Surprisingly, OqxAB has been reported only in clinical isolates of K. pneumoniae from China, South Korea, and Spain.

description: Benzo(a)pyrene (BaP) is a hydrocarbon present in aquatic systems derived from various anthropogenic activities. This compound can be bioaccumulated in aquatic organisms of economic importance and because it is considered carcinogenic and mutagenic, it may present adverse effects on the development of reproductive organs. Therefore, its early detection is important at the molecular level in aquatic organisms using RNA-sequencing (RNA-seq) omic techniques, which have revolutionized the characterization of changes in their transcriptome. However, there is an accelerated progress in the development of so many data analysis methods developed for RNA-Seq analysis. It is not yet clear which criteria to choose to select the most appropriate method, especially for a basic user without a solid statistical or computational background. Thus, in order to help to select the best method, we focused on performing a systematic comparison of two widely used Bioconductor packages and pipelines (Cuffdiff, DESeq2, Rsubread, BioMart, CummeRbund and ClusterProfiler) to determine the differential expression genes (DEG) analysis and gene set enrichment analysis (GSEA) between sample groups. Tilapia were exposed via intraperitoneal injection to repeated doses (3mg/Kg of BaP) for 26 d of exposure to provide general guidelines for choosing a robust pipeline. Our results revealed that 1,173 and 809 DEG were affected by BaP using Cuffdiff and DESeq2 respectively applying a p-adjust value. For further evaluation, we explored the transcriptomic responses in both methods. This evaluation revealed that both analysis showed some similar transcriptomic responses, but most results differed between both methods. We identified 432 transcripts having the same patterns of expression between the two methods. In addition, we used only the 432 DEG for the GSEA analysis using the KEGG database. We found that the enriched GO categories for biological processes were consistent using the ClusterProfiler package and g:Profiler plaftform website. The most significant results for the enriched GO categories for biological processes were monocarboxylic acid metabolic processes, acyl-CoA biosynthetic processes and fatty acid metabolic processes among others. For molecular function, statistical differences were found for catalytic activity, oxidoreductase activity and carboxylic ester hydrolase activity, and for GO terms of cellular component differences were with endoplasmic reticulum membrane and endoplasmic reticulum subcompartment. The GSEA using the KEGG database for tilapia revealed only two enriched pathways: Glycerolipid metabolism and PPAR signaling pathway. At the pathway level, both packages show similar results. Our study shows and demonstrates how data analysis tools can markedly affect the outcome of results, highlighting the importance of taking into account the best option.
