description: Cooper pairing of spatially separated electrons and holes in graphene bilayer is studied beyond the mean-field approximation. Suppression of the screening at large distances, caused by appearance of the gap, is considered self-consistently. A mutual positive feedback between appearance of the gap and enlargement of the interaction leads to a sharp transition to correlated state with greatly increased gap above some critical value of the coupling strength. At coupling strength below the critical, this correlation effect increases the gap approximately by a factor of two. The maximal coupling strength achievable in experiments is close to the critical value. This indicated importance of correlation effects in closely-spaced graphene bilayers at weak substrate dielectric screening. Another effect beyond mean-field approximation considered is an influence of vertex corrections on the pairing, which is shown to be very weak.

Subjects: Medication error (ME); knowledge, attitude and practices (KAP); medication error reporting system (MERS)

description: Introduction: Medication error (ME) is any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the healthcare professional, patient or consumer. And, medication error reporting system (MERS) is a voluntary and non- punitive reporting system that was introduced by the MOH in 2009 to propose remedial actions and monitor the situations in an effort to minimize reoccurrence of such error and thus improve patient safety. Several studies have demonstrated underreporting of ME among healthcare. Multiple ME awareness road shows had been conducted by pharmacy department to related healthcare providers but the impact is unknown. Objective: This study was conducted to assess the knowledge, attitude and practices (KAP) towards medication errors and medication error reporting system among healthcare providers in Hospital Melaka. Methods: Questionnaires were distributed to total number of 360 healthcare workers from January to February 2019 to assess KAP towards ME and MERS. Participants who were unwilling to participate in study, incomplete questionnaire and healthcare workers who were not involved in prescribing services were excluded from this study. Professionals include pharmacists and doctors, whilst non-professionals involve nurses, pharmacist assistants, medical assistants.  Results: Professionals had median mark (IQR) of 9(2) compared to 8(3) in non-professionals for knowledge on ME (p=0.008). Professionals had median mark of 14(6) compared to 13(7) by non-professionals for knowledge on MERS (p<0.0001). Professionals had median mark of 40(5) compared to 39(4) by non-professionals for attitude on ME reporting (p<0.001). Professionals had median mark of 6(5) compared to 5(3) from non-professionals for practice on ME reporting (p<0.001). Years of service in Ministry of Health does not affect knowledge on KAP on ME (p=0.869), MERS (p=0.169), attitude (p=0.502) and practice (p=0.761) on ME reporting significantly. Conclusion: This study showed that professionals group of healthcare providers have overall better knowledge on ME and MERS, better attitude and practice on ME reporting as compared to non- professional group. However, the years of service in MOH does not affect the knowledge of KAP on ME and MERS among the healthcare providers. More program should be carried out to improve awareness and importance of ME reporting system among healthcare providers.

description: Amplification DDoS attacks remain a prevalent and severe threat to the Internet, with recent attacks reaching the Tbps range. However, all amplification attack vectors known to date were either found by researchers through laborious manual analysis or could only be identified postmortem following large attacks. Ideally, though, an attack vector is discovered and mitigated before the first attack can occur. To this end, we present AMPFUZZ, the first systematic approach to finding amplification vectors in UDP services in a protocol-agnostic way. AMPFUZZ is based on the state-of-the-art greybox fuzzing boosted by a novel technique to make fuzzing UDP-aware, which significantly increases performance. We evaluate AMPFUZZ on 28 Debian network services, where we (re-)discover 7 known and 6 previously unreported amplification vulnerabilities.

description: © 2019 by the authors. Transverse thermoelectric materials can achieve appreciable cooling power with minimal space requirement. Among all types of material candidates for transverse thermoelectric applications, composite materials have the best cooling performance. In this study, anisotropic material properties were applied to the component phase of transverse thermoelectric composites. A mathematical model was established for predicting the performance of fibrous transverse thermoelectric composites with anisotropic components. The mathematical model was then validated by finite element analysis. The thermoelectric performance of three types of composites are presented, each with the same set of component materials. For each type of component, both anisotropic single-crystal and isotropic polycrystal material properties were applied. The results showed that the cooling capacity of the system was improved by introducing material anisotropy in the component phase of composite. The results also indicated that the orientation of the anisotropic component's property axis, the anisotropic characteristic of a material, will significantly influence the thermoelectric performance of the composite. For a composite material consisting of Copper fiber and Bi2Te3 matrix, the maximum cooling capacity can vary as much as 50% at 300 K depending on the property axis alignment of Bi2Te3 in the composite. The composite with Copper and anisotropic SnSe single crystal had a 51% improvement in the maximum cooling capacity compared to the composite made of Copper and isotropic SnSe polycrystals.

Subjects: Hysterectomy; minilaparotomy Hysterectomy

description: Introduction: Hysterectomy is often performed as the definitive treatment for benign uterine diseases. Vaginal hysterectomy is the most preferred route followed by laparoscopic approach based on evidence in view of their excellent intra- and post-surgery outcomes compared to conventional abdominal hysterectomy. Minilaparotomy approach emerges as an effective alternative for hysterectomy when vaginal or laparoscopic route is difficult or not feasible. It employs traditional open techniques with less invasive surgical access hence shorter learning curve and more cost-effective than laparoscopic procedures yet comparably postoperative recovery. Our objective is to report on our experience with minilaparotomy hysterectomy. Materials and methods: Data was retrospectively collected from the medical records of all patients who underwent minilaparotomy hysterectomy in a single medical centre over three-year duration from 1st January 2018 to 31st December 2020. Results: There were a total of 10 cases reviewed. The age of patients range between 42 to 77 years. 2 had previous surgery and 4 with underlying comorbidity. Discussion/ Conclusions: In this study we found that minilaparotomy hysterectomy is safe and feasible surgical approach for women with benign uterine diseases, particularly for women with large uterus. It offers shorter operative duration than laparoscopic route yet comparably postoperative recovery. The use of traditional open technique allows more rapid conversion to normal laparotomy compared to vaginal and laparoscopic route. Its minimally invasive approach improves the postoperative outcomes with shorter hospital stay and better cosmetic outcomes as compared to conventional abdominal hysterectomy. The use of traditional instruments is cost-effective and with its short learning curve making it more available even in low-resource settings. It should be considered as valid option when vaginal or laparoscopic-assisted vaginal hysterectomy is difficult or contraindicated.

description: We study transport in two-terminal metal/quantum spin-Hall insulator (QSHI)/metal junctions. We show that the conductance signals originating from the bulk and the edge contributions are not additive. While for a long junction the transport is determined by the edge states contribution, for a short junction, the conductance signal is built from both bulk and edge states in the ratio which depends on the width of the sample. Further, in the topological insulator regime the conductance for short junctions shows a non-monotonic behavior as a function of the sample length. Surprisingly this non-monotonic behavior of conductance can be traced to the formation of an effectively propagating solution which is robust against scalar disorder. Our predictions should be experimentally verifiable in HgTe QWs and Bi$_2$Se$_3$ thin films.

description: Let $D=(V,A)$ be an acyclic digraph. For $x\in V$ define $e_{_{D}}(x)$ to be the difference of the indegree and the outdegree of $x$. An acyclic ordering of the vertices of $D$ is a one-to-one map $g: V \rightarrow [1,|V|] $ that has the property that for all $x,y\in V$ if $(x,y)\in A$, then $g(x) < g(y)$.

We prove that for every acyclic ordering $g$ of $D$ the following inequality holds:
\[\sum_{x\in V} e_{_{D}}(x)\cdot g(x) ~\geq~ \frac{1}{2} \sum_{x\in V}[e_{_{D}}(x)]^2~.\]
The class of acyclic digraphs for which equality holds is determined as the class of comparability digraphs of posets of order dimension two.

Aedes albopictus is a viable vector for several infectious diseases such as Zika, West Nile, Dengue viruses and others. Originating from Asia, this invasive species is rapidly expanding into North American temperate areas and urbanized places causing major concerns for public health. Previous analyses show that warm temperatures and high humidity during the mosquito season are ideal conditions for A. albopictus development, while its distribution is correlated with population density. To better understand A. albopictus expansion into urban places it is important to consider the role of both environmental and neighborhood factors. The present study aims to assess the relative importance of both environmental variables and neighborhood factors in the prediction of A. albopictus’ presence in Southeast Pennsylvania using MaxEnt (version 3.4.1) machine-learning algorithm. Three models are developed that include: (1) exclusively environmental variables, (2) exclusively neighborhood factors, and (3) a combination of environmental variables and neighborhood factors. Outcomes from the three models are compared in terms of variable importance, accuracy, and the spatial distribution of predicted A. albopictus’ presence. All three models predicted the presence of A. albopictus in urban centers, however, each to a different spatial extent. The combined model resulted in the highest accuracy (74.7%) compared to the model with only environmental variables (73.5%) and to the model with only neighborhood factors (72.1%) separately. Although the combined model does not essentially increase the accuracy in the prediction, the spatial patterns of mosquito distribution are different when compared to environmental or neighborhood factors alone. Environmental variables help to explain conditions associated with mosquitoes in suburban/rural areas, while neighborhood factors summarize the local conditions that can also impact mosquito habitats in predominantly urban places. Overall, the present study shows that MaxEnt is suitable for integrating neighborhood factors associated with mosquito presence that can complement and improve species distribution modeling.
Density dichotomy in random words

description: Word $W$ is said to encounter word $V$ provided there is a homomorphism $\phi$ mapping letters to nonempty words so that $\phi(V)$ is a substring of $W$. For example, taking $\phi$ such that $\phi(h)=c$ and $\phi(u)=ien$, we see that ``science'' encounters ``huh'' since $cienc=\phi(huh)$. The density of $V$ in $W$, $\delta(V,W)$, is the proportion of substrings of $W$ that are homomorphic images of $V$. So the density of ``huh'' in ``science'' is $2/{8 \choose 2}$. A word is doubled if every letter that appears in the word appears at least twice.

The dichotomy: Let $V$ be a word over any alphabet, $\Sigma$ a finite alphabet with at least 2 letters, and $W_n \in \Sigma^n$ chosen uniformly at random. Word $V$ is doubled if and only if $\mathbb{E}(\delta(V,W_n)) \rightarrow 0$ as $n \rightarrow \infty$.

We further explore convergence for nondoubled words and concentration of the limit distribution for doubled words around its mean.

description: © 2018 IEEE. In this paper, we propose a new randomized response algorithm that can achieve differential-privacy and utility guarantees for consumer's behaviors, and process a batch of data at each time. Firstly, differing from traditional differential private approach-es, we add randomized response noise into the behavior signa-tures matrix to achieve an acceptable utility-privacy tradeoff. Secondly, a behavior signature modeling method based on sparse coding is proposed. After some lightweight trainings us-ing the energy consumption data, the dictionary will be associat-ed with the behavior characteristics of the electric appliances. At last, through the experimental results verification, we find that our Algorithm can preserve consumer's privacy without comprising utility.
The inclusion of musical knowledge and perspectives of a First Nation in three Ontario mainstream schools

description: Ministry of Education policy guidelines (e.g., 2007) call upon educators in Ontario to include cultural knowledge and perspectives of First Peoples in their school practice, and recent provincial arts curricula encourage inclusion of and instruction on music and related knowledge of Aboriginal Peoples. But mainstream music teachers commonly lack knowledge about music of Native North American cultures and culturally appropriate ways of teaching it, instead using approaches and materials that are predicated upon Western notions of music, musicianship, and instructional method (Bowman, 2007). This study, grounded theoretically in critical pedagogy (Kincheloe, 2008) and a constructivist dialogic approach to understanding (Gadamer, 2004/1975), had two purposes: (1) to construct understandings about the school teaching of music of one First Nation cultural group that were voiced by cultural practitioners from that group, and (2) to critically examine changes in teachers’ practices as they engaged with music and related knowledge following their mentoring with these practitioners. Case study method was used in a survey of five mentoring events in which First Nations mentors, most of whom were associated with the Iroquoian cultural group, shared music and related knowledge in mainstream school classrooms. Mentors communicated six clusters of interconnected values—characterized as “who we are and where we come from,” keeping knowledge alive, responsibility, relationship, respect, and “connection and wholeness”—associated with their school sharing of music and related knowledges. They suggested that teachers learn local music from a community cultural teacher and teach music in context with other cultural, historical, and place-based knowledge. The teachers found that accuracy, the importance of story and teachings, and the notion of connection, particularly connection to nature, were significant. While some teachers focused on musical understandings, the teacher who interacted most with community members communicated values that more closely reflected values shared by the mentors. Openness, initiative, and continued interaction with community members promoted change in her practice and her consideration of epistemological, decolonizing, and restorative functions associated with teaching music and knowledge of a First Nation. Through personal reflective ethnography, the researcher examined changes in her own understanding as she engaged in this research.

description: The main objective of the present work is the development of an analytically tractable model of screened electron-electron and electron-exciton interactions in layered systems composed of two parallel semiconductor quantum wells separated by a dielectric layer. These systems are promising for superconductivity with excitons-polaritons, and spin manipulation. Polarization effects induced by the dielectric mismatch in the nanostructure are taken into account using the image charge method. The obtained analytic expressions are used to calculate screened electron-electron and electron-exciton interactions; these are compared to results computed using other recently published models.

description: Many experiments are currently using or proposing to use large area GEM foils in their detectors, which is creating a need for commercially available GEM foils. Currently CERN is the only main distributor of large GEM foils, however with the growing interest in GEM technology keeping up with the increasing demand for GEMs will be difficult. We present here an update on the assembly and testing of triple-GEM tracking detectors utilizing single-masked $40 \times 40$ cm$^2$ commercial GEM foils produced by Tech-Etch. The triple-GEM detectors will allow us to characterize the overall quality of these Tech-Etch foils through gain, efficiency, and energy resolution measurements. This will be done by constructing four single-mask triple-GEM detectors, using foils manufactured by Tech-Etch, which follow the design used by the STAR Forward GEM Tracker (FGT). The stack is formed by gluing the foils to the frames and then gluing the frames together. The stack also includes a Tech-Etch produced high voltage foil and a 2D $r-\phi$ readout foil. While one of the four triple-GEM detectors will be built identically to the STAR FGT, the other three will investigate ways in which to further decrease the material budget and increase the efficiency of the detector by incorporating perforated Kapton spacer rings rather than G10 spacing grids to reduce the dead area of the detector.

We carried out a retrospective observational study of 264 HER2-positive advanced breast cancer (ABC) patients to explore the efficacy of first-line treatment with pertuzumab/trastuzumab/taxane in real-world setting. Survival data were analyzed by Kaplan Meier curves and log rank test. Median follow-up, length of pertuzumab/trastuzumab/taxane treatment and of pertuzumab, trastuzumab maintenance were 21, 4 and 15 months, respectively. The response rate was 77.3%, and the clinical benefit rate 93.6%. Median progression-free survival (mPFS) was 21 months, and median overall survival (mOS) was not reached. When comparing patients by trastuzumab-pretreatment, similar PFS were observed, although a longer OS was reached in trastuzumab-naïve patients (p = 0.02). Brain metastases at baseline and their development in course of therapy were associated with significantly shorter PFS (p = 0.0006) and shorter OS, although at a not fully statistically relevant extent (p = 0.06). The addition of maintenance endocrine therapy (ET) to pertuzumab/trastuzumab maintenance was associated with longer PFS (p = 0.0001), although no significant differences were detected in OS (p = 0.31). Results were confirmed by propensity score analysis (p = 0.003 and p = 0.46, respectively). In multivariate models, longer PFS was related to lower Performance Status (PS) (p = 0.07), metastatic stage at diagnosis (p = 0.006) and single metastatic site (p

description: Â© Ho and Zdilla 2018 Tolnaftate, a classic antifungal compound, has been found to crystallize from 1:1 (v/v) acetoneâ€“water as large flat colorless needles in the centrosymmetric monoclinic space group P21/c. These crystals contain a 50:50 mixture of the (+ap,âˆ’sp,+ac,âˆ’ac) and (âˆ’ap,+sp,âˆ’ac,+ac) conformers. The bond lengths in the central CNOS unit are 1.3444 (19), 1.3556 (18) and 1.6567 (15) Ã… for Câ€”N, Câ€”O and Câ€”S, respectively, and the CNOS and C3N moieties are flat and nearly coplanar with each other, consistent with the Câ€”N bond possessing partial double-bond character. Tolnaftate and the four most closely related N,N-disubstituted thiocarbamates in the Cambridge Structural Database (CSD) all exist as E-conformational isomers in the solid state. Among these five compounds, tolnaftate is the only one in which the N-tolyl moiety is positioned trans to the S atom, i.e. the N-aryl substituent in each of the other compounds is positioned cis to their respective S atom. Notably, and more importantly, our experimental X-ray structure is unlike all prior theoretical models available for tolnaftate. The implication, either directly or indirectly, is that some of those theoretical models used in earlier studies to explain the spectroscopic properties of tolnaftate and to suggest which proteinâ€“ligand interactions are responsible for the binding of tolnaftate to squalene epoxidase are either inappropriate or structurally unreasonable, i.e. the results and conclusions from those prior studies are in need of critical reassessment.

description: © 2005-2012 IEEE. The advances of cloud computing, fog computing, and Internet of things (IoT) make industries more prosperous than ever. A wide range of industrial systems such as transportation and manufacturing systems have been developed by integrating cloud computing, fog computing, and IoT infrastructure successfully. However, in this sophisticated system, security and privacy issues are major concerns that hinder the widespread adoptions of these novel techniques. In this paper, we focus on assured data deletion, an issue that is important but received less attention in academia and industry. We first propose a framework to integrate the cloud, the fog, and the things together to manage stored data from industries or individuals. We then focus on secure data deletion in this framework by proposing an assured data deletion scheme that fulfills verifiable data deletion as well as flexible access control over sensitive data. Only data owners and fog devices are involved when deleting cloud data and validating the deletion of these data, which makes the protocol practical due to the features of low latency as well as real-Time interaction with fog. The proposed protocol takes advantage of the attribute-based encryption, whose security can be proved under the standard model. The theoretical analysis shows good performance and functionality requirements while the implementation results demonstrate the feasibility of our proposal.

description: Introduction: Previous studies have suggested that the involvement of serotonergic and N-methyl-D-aspartate (NMDA) glutamate receptor complex dysfunction in the pathophysiology of several neuropsychiatric disorders. However, the exact association with bipolar disorder remains unclear. Hence, the purpose of this study was to measure plasma concentrations of glutamate, glycine and tryptophan in bipolar disorder patients and compared with the healthy controls. Methods: A case-control study was conducted from October 2017 till June 2018 in Hospital Universiti Sains Malaysia (HUSM). We had measured the plasma levels of glutamate, glycine and tryptophan in 83 bipolar patients and data were compared to a group of 82 healthy controls using high performance liquid chromatography (HPLC) method. Results: The mean (SD) age of bipolar patients were 40.87 (12.08) while the mean (SD) age for control groups was 35.60 (7.68) years. The participants from the bipolar group and control group differ significantly in age (p=0.001), however, there was no significant difference between patients and controls with respect to gender. Discussion: The present study demonstrates increased in plasma levels of glutamate and glycine in all episodes of bipolar disorder patients, more markedly in manic phase as compared to the healthy control group. These results are consistent with those found in previous studies which also documented an elevated level of glutamate and glycine in bipolar patients. Conclusion: The results suggested that these amino acids could be used as one of the peripheral biomarkers to aid in the diagnosis of bipolar disorder. Thus, also helping to describe the development, potential treatment and more importantly for early diagnosis of susceptible patients to bipolar disorder in future.

description: © 2018, The Author(s). Bats of western North America face many threats, but little is known about current population changes in these mammals. We compiled 283 surveys from 49 hibernacula over 32 years to investigate population changes of Townsend’s big-eared bats (Corynorhinus townsendii townsendii) and western small-footed myotis (Myotis ciliolabrum) in Idaho, USA. This area comprises some of the best bat habitat in the western USA, but is threatened by land-use change. Bats in this area also face invasion by the pathogen causing white-nose syndrome. Little is known about long-term trends of abundance of these two species. In our study, estimated population changes for Townsend’s big-eared bats varied by management area, with relative abundance increasing by 186% and 326% in two management areas, but decreasing 55% in another. For western small-footed myotis, analysis of estimated population trend was complicated by an increase in detection of 141% over winter. After accounting for differences in detection, this species declined region-wide by 63% to winter of 1998–1999. The population fully recovered by 2013–2014, likely because 12 of 23 of its hibernacula were closed to public access from 1994 to 1998. Our data clarify long-term population patterns of two bat species of conservation concern, and provide important baseline understanding of western small-footed myotis prior to the arrival of white-nose syndrome in this area.

description: Intel's Software Guard Extensions (SGX) provide a non-introspectable trusted execution environment (TEE) to protect security-critical code from a potentially malicious OS. This protection can only be effective if the individual enclaves are secure, which is already challenging in regular software, and this becomes even more difficult for enclaves as the entire environment is potentially malicious. As such, many enclaves expose common vulnerabilities, e.g., memory corruption and SGX-specific vulnerabilities like null-pointer dereferences. While fuzzing is a popular technique to assess the security of software, dynamically analyzing enclaves is challenging, as enclaves are meant to be non-introspectable. Further, they expect an allocated multi-pointer structure as input instead of a plain buffer. In this paper, we present SGXFuzz, a coverage-guided fuzzer that introduces a novel binary input structure synthesis method to expose enclave vulnerabilities even without source-code access. To obtain code coverage feedback from enclaves, we show how to extract enclave code from distribution formats. We also present an enclave runner that allows execution of the extracted enclave code as a user-space application at native speed, while emulating all relevant environment interactions of the enclave. We use this setup to fuzz enclaves using a state-of-the-art snapshot fuzzing engine that deploys our novel structure synthesis stage. This stage synthesizes multi-layer pointer structures and size fields incrementally on-the-fly based on fault signals. Furthermore, it matches the expected input format of the enclave without any prior knowledge. We evaluate our approach on 30 open and closed-source enclaves and found a total of 79 new bugs and vulnerabilities.

One proposed explanation is that HIV-1 gag or gp41 cytoplasmic domain mutations might also reduce PI susceptibility. In a recent study of paired gag and gp41 sequences from individuals with virological failure on a PI regimen, we did not identify PI-selected mutations and concluded that if such mutations existed, larger numbers of paired sequences from multiple studies would be needed for their identification. In this study, we generated site-specific amino acid profiles using gag and gp41 published sequences from 5,338 and 4,242 ART-naïve individuals, respectively, to assist researchers identify unusual mutations arising during therapy and to provide scripts for performing established and novel maximal likelihood estimates of dN/dS substitution rates in paired sequences. The pipelines used to generate the curated sequences, amino acid profiles, and dN/dS analyses will facilitate the application of consistent methods to paired gag and gp41 sequence datasets and expedite the identification of potential sites under PI-selection pressure.

description: We describe our procedure to determine effective temperatures, rotational velocities, microturbulent velocities, and chemical abundances in the atmospheres of Sun-like stars. We use independent determinations of iron abundances using the fits to the observed Fe I and Fe II atomic absorption lines. We choose the best solution from the fits to these spectral features for the model atmosphere that provides the best confidence in the determined log N(Fe), Vt, and vsini. First, we compute the abundance of iron for a set of adopted microturbulent velocities. To determine the most self-consistent effective temperature and microturbulent velocity in any star's atmosphere, we used an additional constraint where we minimise the dependence of the derived abundances of Fe I and Fe II on the excitation potential of the corresponding lines. We analyse the spectra of the Sun and two well known solar type stars, HD1835 and HD10700 to determine their abundances, microturbulent velocity and rotational velocity. For the Sun abundances of elements obtained from the fits of their absorption features agree well enough (+/- 0.1 dex) with the known values for the Sun. We determined a rotational velocity of vsini = 1.6 +/- 0.3 km/s for the spectrum of the Sun as a star. For HD1835 the self-consistent solution for Fe I and Fe II lines log N(Fe)=+0.2 was obtained with a model atmosphere of 5807/4.47/+0.2 andmicroturbulent velocity Vt = 0.75 km/s, and leads to vsini = 7.2 $\pm$ 0.5 km/s. For HD10700 the self-consistent solution log N(Fe) = -4.93 was obtained using a model atmosphere of 5383/4.59/-0.6and microturbulent velocity Vt = 0.5 km/s. The Fe I and Fe II lines give rise to a vsini = 2.4 +/- 0.4 km/s. Using the Teff found from the ionisation equilibrium parameters for all three stars, we found abundances of a number of other elements: Ti, Ni, Ca, Si, Cr. ... Abriged.

description: © 2018 IOP Publishing Ltd and Sissa Medialab. This paper describes the design and performance of a 50 liter, two-segment 6Li-loaded liquid scintillator detector that was designed and operated as prototype for the PROSPECT (Precision Reactor Oscillation and Spectrum) Experiment. The two-segment detector was constructed according to the design specifications of the experiment. It features low-mass optical separators, an integrated source and optical calibration system, and materials that are compatible with the 6Li-doped scintillator developed by PROSPECT. We demonstrate a high light collection of 850±20 PE/MeV, an energy resolution of σ = 4.0±0.2% at 1 MeV, and efficient pulse-shape discrimination of low dE/dx (electronic recoil) and high dE/dx (nuclear recoil) energy depositions. An effective scintillation attenuation length of 85±3 cm is measured in each segment. The 0.1% by mass concentration of 6Li in the scintillator results in a measured neutron capture time of τ = 42.8±0.2 μs. The long-term stability of the scintillator is also discussed. The detector response meets the criteria necessary for achieving the PROSPECT physics goals and demonstrates features that may find application in fast neutron detection.
A search for AdS5 X S2 IIB supergravity solutions dual to N = 2 SCFTs

description: We present a systematic search for Type IIB supergravity solutions whose spacetimes include AdS5 and S2 factors, which would be candidate duals to N = 2 four-dimensional Superconformal field theories. The candidate solutions encode the SU(2) R-symmetry geometrically on the S2 and an additional Killing vector generates the U(1) R-symmetry. By analysing the Killing spinor equations we show that no such solutions exist. This suggests that, if Type IIB backgrounds dual to N = 2 SCFTs exist, the SU(2) R-symmetry is realised non-geometrically. Finally, we also show that, in the context of both N = 1 and N = 2 Type IIB backgrounds with an AdS5 factor, the only candidate U(1) R-symmetry Killing vector directions are the ones that appear for generic values of the Killing spinors; no further Killing vectors exist for special values of the Killing spinors.

On (1 + ϵ)-Approximate Block Sparse Recovery

description: Learning approximately block sparse vectors using a small number of linear measurements is a standard task in the sparse recovery/compressed sensing literature. Schemes achieving a constant factor approximation are long known, e.g. using model-based RIP. We give a new scheme achieving (1+\epsilon) approximation, which runs in near linear time in the length of the vector and is likely to be optimal up to constant factors. As an intriguing side result, we obtain the simplest known scheme measurement-optimal \ell_2/\ell_2 sparse recovery scheme recorded in the literature. The main component of our algorithm is a subtle variant of the classic CountSketch data structure where the random signs are substituted by gaussians and the number of repetitions (rows) is tuned to smaller than usual.

description: We investigated the dynamics of single soft nano-tubes of phospholipids to extract nano-scale information such as size of tube, which are several tens to hundreds of nano-meters thick. The scaling law of the nano-tube dynamics in quasi-2-dimensional space was revealed to be constituent with that of a polymer. The dynamic properties of the tubes obtained from direct observation by fluorescent microscopy, such as their persistence length, enable us to access the nano-scale characteristics through a simple elastic model of the membrane. The present methodology should be applicable to the nano-sized membrane structure in living cells.

description: We investigate numerically by a conservative difference scheme in complex arithmetic the head-on and takeover collision dynamics of the solitary waves as solutions of linearly Coupled Nonlinear Schrödinger Equations for various initial phases. The initial conditions are superposition of two one-soliton solutions with general polarization. The quasi-particle behavior of propagating and interacting solutions in conditions of rotational polarization is examined. We find that the total mass, pseudomomentum and energy are conserved while the local masses, individual and total polarization depend strongly on the linear coupling and the initial phase difference. We also find out that the polarization angle of the quasi-particles can change independently of the interaction.

A Recursive Early-Stopping Phase King Protocol

description: Early-stopping consensus protocols guarantee termination within a number of rounds that depends only on the actual number ???? of faulty nodes in a run, not the maximum number of faults that can be tolerated. We consider early-stopping deterministic synchro- nous consensus with Byzantine faults in a fully connected message passing system of ???? nodes. Many such protocols are known, but so far none combine early-stopping in ????(???? + 1) rounds with optimal resilience and a bit complexity of ????(????2(???? + 1)). We provide two solutions to the above problem. The first is a low- hanging fruit that almost matches the above requirements, but has worst-case message and bit complexities of Θ(????2 log(???? + 2)). The second reduces the bit complexity further to ????(????2) at the expense of increasing the constant factor in the running time bound. It does so by calling itself recursively at most twice on Θ(????)-sized subsets. This presents a substantial technical hurdle, since it is not known when the recursive call will terminate, and relying on a worst-case bound would lose the property of stopping early. We overcome this obstacle by introducing a (re-)synchronization barrier in the calling routine that forces all correct nodes to proceed in its execution within one round of each other, complemented by a simple mechanism to simulate synchronous execution in this almost synchronized setting. The result is the first protocol that is simultenously optimally resilient, asymptotically optimally early- stopping, and asymptotically bit- and message-optimal.
