description: Contemporary research suggests that the reionisation of the intergalactic medium (IGM) in the early Universe was predominantly realised by star-forming (proto-)galaxies (SFGs). Due to observational constraints, our knowledge on the origins of sufficient amounts of ionising Lyman continuum (LyC) photons and the mechanisms facilitating their transport into the IGM remains sparse. Recent efforts have thus focussed on the study of local analogues to these high-redshift objects. We used archival spectroscopic SDSS DR12 data to select a sample of low-z He II 4686 emitters and restricted it to a set of SFGs with an emission line diagnostic sensitive to the presence of an AGN, which serves as our only selection criterion. Our final sample consists of eighteen low-mass, low-metallicity dwarf galaxies which appear to be predominantly ionised by stellar sources. We find large O32 ratios and [S II] deficiencies, which provide strong indications for these galaxies to be LyC Emitters (LCEs). At least 40% of these objects are candidates for featuring cosmologically significant LyC escape fractions >10%. Their SFHs exhibit strong similarities and almost all galaxies appear to contain an old (>1 Gyr) stellar component, while also harbouring a young, two-stage (~10 Myr and <1 Myr) starburst, which we speculate might be related to LyC escape. The properties of the compact emission line galaxies presented here align well with those observed in many local LCEs. In fact, our sample may prove as an extension to the rather small catalogue of local LCEs, as the extreme interstellar medium (ISM) conditions we find are assumed to facilitate LyC leakage. Notably, all of our eighteen candidates are significantly closer (z<0.1) than most established LCEs. If the inferred LyC photon loss is genuine, this demonstrates that selecting SFGs from He II 4686 is a powerful selection criterion in the search for LCEs.

The ubiquitin ligase MuRF1 regulates PPARα activity in the heart by enhancing nuclear export via monoubiquitination
Creators: name: Willis, Monte S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The transcriptional regulation of peroxisome proliferator-activated receptor (PPAR) α by post-translational modification, such as ubiquitin, has not been described. We report here for the first time an ubiquitin ligase (muscle ring finger-1/MuRF1) that inhibits fatty acid oxidation by inhibiting PPARα, but not PPARβ/δ or PPARγ in cardiomyocytes in vitro. Similarly, MuRF1 Tg+ hearts showed significant decreases in nuclear PPARα activity and acyl-carnitine intermediates, while MuRF1−/− hearts exhibited increased PPARα activity and acyl-carnitine intermediates. MuRF1 directly interacts with PPARα, mono-ubiquitinates it, and targets it for nuclear export to inhibit fatty acid oxidation in a proteasome independent manner. We then identified a previously undescribed nuclear export sequence in PPARα, along with three specific lysines (292, 310, 388) required for MuRF1s targeting of nuclear export. These studies identify the role of ubiquitination in regulating cardiac PPARα, including the ubiquitin ligase that may be responsible for this critical regulation of cardiac metabolism in heart failure.
Developmental regulation of GABAergic interneuron branching and synaptic development in the prefrontal cortex by soluble neural cell adhesion molecule

description: Neural cell adhesion molecule, NCAM, is an important regulator of neuronal process outgrowth and synaptic plasticity. Transgenic mice that overexpress the soluble NCAM extracellular domain (NCAM-EC) have reduced GABAergic inhibitory and excitatory synapses, and altered behavioral phenotypes. Here, we examined the role of dysregulated NCAM shedding, modeled by overexpression of NCAM-EC, on development of GABAergic basket interneurons in the prefrontal cortex. NCAM-EC overexpression disrupted arborization of basket cells during the major period of axon/dendrite growth, resulting in decreased numbers of GAD65- and synaptophysin-positive perisomatic synapses. NCAM-EC transgenic protein interfered with interneuron branching during early postnatal stages when endogenous polysialylated (PSA) NCAM was converted to non-PSA isoforms. In cortical neuron cultures, soluble NCAM-EC acted as a dominant inhibitor of NCAM-dependent neurite branching and outgrowth. These findings suggested that excess soluble NCAM-EC reduces perisomatic innervation of cortical neurons by perturbing axonal/dendritic branching during cortical development.

Analysis and Comparison of the Thermal Retention Properties of Shading Devices in the Real-World and Dynamic Thermal Models within the UK Built Environment
Creators: name: Salehi, Bahareh
Publisher: name: London South Bank University
Year: 2022

description: The built environment accounts for 40% of the UK’s carbon footprint, with half of this involving building operations. Additionally, as approximately 50% of the building energy is linked to heating applications, managing thermal loss has become critical in reducing the energy load of buildings. One of the methods to reduce heat loss in buildings is utilising shaded devices. However, most research into the effectiveness of utilising window coverings to reduce heat loss has been carried out in experimental situations within a controlled laboratory, which does not reflect real-life conditions. To investigate the gap in knowledge in the UK around the use of shading devices, a survey study was conducted with the participation of UK building industry professionals. The results highlighted the lack of awareness of the impact shading devices can have on thermal retention. To assess the effects of shading devices on thermal retention, two real-world case studies were conducted using internal cellular blinds. These studies illustrated the importance of correct installation methods when using shading devices, as well as the effectiveness of sealed blinds in reducing heat loss through windows. A further survey was conducted to evaluate the effectiveness of BEMS software packages in modelling shading devices amongst UK building energy modellers which indicated that the software databases had insufficient information on shading devices. To further assess the capability of BEMS software packages illustrating the impact of shading devices, the results from the case study were compared with dynamic thermal model results generated by four software packages. The real-world study demonstrated a positive trend between the correct use of shading devices and the reduction of key energy performance indicators, such as heat loss and heating energy consumption. By comparing this to the results from the simulations, inefficiencies in the software were exposed specifically when assessing the total heating consumption.

Here we give explicit ADHM data corresponding to axial hyperbolic monopoles in a simple, tractable form, as well as expressions for the axial monopole fields. The data is deformed into new 1-parameter families preserving dihedral and twisted-line symmetries. In many cases explicit expressions are presented for their spectral curves and rational maps of both Donaldson and Jarvis type.

description: With the increasing importance of distributed systems as a computing paradigm, a systematic approach to their design is needed. Although the area of formal verification has made enormous advances towards this goal, the resulting functionalities are limited to detecting problems in a particular design. By means of a classical example, we illustrate a simple template-based approach to computer-aided design of distributed systems based on leveraging the well-known technique of bounded model checking to the synthesis setting.

description: Six genes in the 1.5 MB region of chromosome 22 deleted in DiGeorge/22q11 Deletion Syndrome—Mrpl40, Prodh, Slc25a1, Txnrd2, T10, and Zdhhc8—encode mitochondrial proteins. All six genes are expressed in the brain, and maximal expression coincides with peak forebrain synaptogenesis shortly after birth. Furthermore, their protein products are associated with brain mitochondria, including those in synaptic terminals. Among the six, only Zddhc8 influences mitochondria-regulated apoptosis when overexpressed, and appears to interact biochemically with established mitochondrial proteins. Zdhhc8 has an apparent interaction with Uqcrc1, a component of mitochondrial complex III. The two proteins are coincidently expressed in presynaptic processes; however, Zdhhc8 is more frequently seen in glutamatergic terminals. 22q11 deletion may alter metabolic properties of cortical mitochondria during early post-natal life, since expression complex III components, including Uqcrc1, is significantly increased at birth in a mouse model of 22q11 deletion, and declines to normal values in adulthood. Our results suggest that altered dosage of one, or several 22q11 mitochondrial genes, particularly during early postnatal cortical development, may disrupt neuronal metabolism or synaptic signaling.

description: Background: Chronic kidney disease (CKD) is a debilitating condition that is becoming more common around the world, as well as a financial and social burden on healthcare systems. If not treated with kidney replacement therapies, kidney failure, the final stage of CKD, can be fatal. Chronic kidney disease patients are now seeking the use of alternative remedies, including medicinal plants, as the primary source of healthcare. Aim: This review aimed to evaluate the use of medicinal plants in the treatment of CKD and other associated kidney diseases in South Africa. Method: This article summarises previous research (2010–2021) on the impact of traditional plant-based medicine in CKD treatment and identifies the context between traditional and conventional medicines. Various scientific databases were used to source key literature. Results: The findings of this study revealed 10 medicinal plant species from nine different botanical families that are commonly used for the treatment of CKD and other kidney-related diseases in South Africa. In addition, the study demonstrated that despite medicinal plants having toxic impacts, they were still the preferred choice of medication for CKD, especially in developing countries. Conclusion: It is crucial to validate the balance between the risks and benefits of medicinal plants in CKD treatment to further enhance the credibility of medical plants in drug development. Contribution: This study contributes to the existing knowledge of medicinal plants used in CKD treatment primarily in South Africa.
title: Developing a method for continuously monitoring dissolved organic carbon concentration in boreal forest headwater streams
Creators: name: Gaviria Salazar, Christian Javier
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Headwater streams are an important medium through which carbon from the landscape is transported into aquatic ecosystems in the form of dissolved organic carbon (DOC), an ecologically significant and, until the last decade, underestimated pool of mobile carbon. Boreal forests contain a great fraction of the worlds terrestrial carbon and are considered a large carbon sink. However, they are vulnerable to climate change and can easily become sources of atmospheric carbon. To better understand how our landscapes are responding to climate change we can monitor DOC within headwater streams which integrate and quickly respond to changes of the surrounding landscape. However, continuous monitoring for DOC is difficult and must be monitored via proxy-measurements. This thesis demonstrates an approach to develop and monitor the performance of a model developed to estimate DOC from UV-VIS absorbance and other data from in-situ probes.

description: Classical novae are shock-powered multi-wavelength transients triggered by a thermonuclear runaway on an accreting white dwarf. V1674 Her is the fastest nova ever recorded (time to declined by two magnitudes is t_2=1.1 d) that challenges our understanding of shock formation in novae. We investigate the physical mechanisms behind nova emission from GeV gamma-rays to cm-band radio using coordinated Fermi-LAT, NuSTAR, Swift and VLA observations supported by optical photometry. Fermi-LAT detected short-lived (18 h) 0.1-100 GeV emission from V1674 Her that appeared 6 h after the eruption began; this was at a level of (1.6 +/- 0.4)x10^-6 photons cm^-2 s^-1. Eleven days later, simultaneous NuSTAR and Swift X-ray observations revealed optically thin thermal plasma shock-heated to kT_shock = 4 keV. The lack of a detectable 6.7 keV Fe K_alpha emission suggests super-solar CNO abundances. The radio emission from V1674 Her was consistent with thermal emission at early times and synchrotron at late times. The radio spectrum steeply rising with frequency may be a result of either free-free absorption of synchrotron and thermal emission by unshocked outer regions of the nova shell or the Razin-Tsytovich effect attenuating synchrotron emission in dense plasma. The development of the shock inside the ejecta is unaffected by the extraordinarily rapid evolution and the intermediate polar host of this nova.

description: Interaction of the cell adhesion molecule L1 with the cytoskeletal adaptor ankyrin is essential for topographic mapping of retinal ganglion cell (RGC) axons to synaptic targets in the superior colliculus (SC). Mice mutated in the L1 ankyrin-binding motif (FIGQY1229H) display abnormal mapping of RGC axons along the mediolateral axis of the SC, resembling mouse mutant phenotypes in EphB receptor tyrosine kinases. To investigate whether L1 functionally interacts with EphBs, we investigated the role of EphB kinases in phosphorylating L1 using a phospho-specific antibody to the tyrosine phosphorylated FIGQY1229 motif. EphB2, but not an EphB2 kinase dead mutant, induced tyrosine phosphorylation of L1 at FIGQY1229 and perturbed ankyrin recruitment to the membrane in L1-transfected HEK293 cells. Src family kinases mediated L1 phosphorylation at FIGQY1229 by EphB2. Other EphB receptors that regulate medial-lateral retinocollicular mapping, EphB1 and EphB3, also mediated phosphorylation of L1 at FIGQY1229. Tyrosine1176 in the cytoplasmic domain of L1, which regulates AP2/clathrin-mediated endocytosis and axonal trafficking, was not phosphorylated by EphB2. Accordingly mutation of Tyr1176 to Ala in L1-Y1176A knock-in mice resulted in normal retinocollicular mapping of ventral RGC axons. Immunostaining of the mouse SC during retinotopic mapping showed that L1 colocalized with phospho-FIGQY in RGC axons in retinorecipient layers. Immunoblotting of SC lysates confirmed that L1 was phosphorylated at FIGQY1229 in wild type but not L1-FIGQY1229H (L1Y1229H) mutant SC, and that L1 phosphorylation was decreased in the EphB2/B3 mutant SC. Inhibition of ankyrin binding in L1Y1229H mutant RGCs resulted in increased neurite outgrowth compared to WT RGCs in retinal explant cultures, suggesting that L1-ankyrin binding serves to constrain RGC axon growth. These findings are consistent with a model in which EphB kinases phosphorylate L1 at FIGQY1229 in retinal axons to modulate L1-ankyrin binding important for mediolateral retinocollicular topography.

description: Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary habitability. A statistical strategy for evaluating the evolutionary pathways of terrestrial planets lies in the atmospheric characterization of exoplanets, where the sample size provides sufficient means for determining required runaway greenhouse conditions. Observations of potential exoVenuses can help confirm hypotheses about Venus' past, as well as the occurrence rate of Venus-like planets in other systems. Additionally, the data from future Venus missions, such as DAVINCI, EnVision, and VERITAS, will provide valuable information regarding Venus, and the study of exoVenuses will be complimentary to these missions. To facilitate studies of exoVenus candidates, we provide a catalog of all confirmed terrestrial planets in the Venus Zone, including transiting and non-transiting cases, and quantify their potential for follow-up observations. We examine the demographics of the exoVenus population with relation to stellar and planetary properties, such as the planetary radius gap. We highlight specific high-priority exoVenus targets for follow-up observations including: TOI-2285 b, LTT 1445 A c, TOI-1266 c, LHS 1140 c, and L98-59 d. We also discuss follow-up observations that may yield further insight into the Venus/Earth divergence in atmospheric properties.

Under general antenna configurations, the sum linear degrees of freedom (LDoF) of the K-user MIMO BC with reconfigurable antennas is completely characterized, which corresponds to the maximum sum DoF achievable by linear coding strategies. The LDoF region is further characterized for a class of antenna configurations. Similar analysis is extended to the K-user MIMO interference channels with reconfigurable antennas and the sum LDoF is characterized for a class of antenna configurations.

description: Murray-Darling Freshwater Research Centre

MDFRC item.

Techniques were developed to collect the periphyton on submerged wood of the River Red Gum (Eucalyptus camaldulensis DEHNH., Myrtaceae) and determine the activity of some key extracellular enzymes associated with these biofilms. Periphyton was grown on wooden tiles placed in the photic zone and the aphotic zone of the water column of two billabongs in south-eastern Australia, and enzyme activities measured with p-nitrophenyl derivatives as substrate analogues. Rates of enzyme activity were calculated per unit periphytic organic-matter (as ash-free dry weight, AFDW) and per unit tile surface area. Phosphatase activity was maximal at either pH 6-7 and 9-10 depending upon site, whereas leucine aminopeptidase and beta-D glucosidase activity were maximal at pH 7-9 and 5-6, respectively. V(max) values for alkaline phosphatase (40-84 nmol mg AFDW-1 h-1) and aminopeptidase (15-556 nmol mg AFDW-1 h-1) were greater than for beta-D glucosidase (6-9 nmol mg AFDW-1 h-1). A similar pattern was evident when rates were expressed on a per cm2 basis. Alkaline phosphatase and aminopeptidase activities were generally greater in the photic zone than the aphotic zone, but there was little effect of position on beta-D glucosidase activity. The K(m) values for alkaline phosphatase, aminopeptidase and beta-D glucosidase ranged from 220-811 mumol l-1, 158-2550 mumol l-1 and 200-826 mumol l-1, respectively. There were few consistent differences in the K(m) values of photic-zone and aphotic-zone periphyton. We conclude that the periphyton associated with submerged wood in billabongs possess active extracellular enzymes, seemingly with a poor affinity for their substrate.

description: For deterministic and probabilistic programs we investigate the problem of program synthesis and program optimisation (with respect to non-functional properties) in the general setting of global optimisation. This approach is based on the representation of the semantics of programs and program fragments in terms of linear operators, i.e. as matrices. We exploit in particular the fact that we can automatically generate the representation of the semantics of elementary blocks. These can then can be used in order to compositionally assemble the semantics of a whole program, i.e. the generator of the corresponding Discrete Time Markov Chain (DTMC). We also utilise a generalised version of Abstract Interpretation suitable for this linear algebraic or functional analytical framework in order to formulate semantical constraints (invariants) and optimisation objectives (for example performance requirements).

description: The study of the multiplicity of massive stars gives hints on their formation processes and their evolutionary paths, which are still not fully understood. Large separation binaries (>50 milliseconds of arc, mas) can be probed by adaptive-optics-assisted direct imaging and sparse aperture masking, while close binaries can be resolved by photometry and spectroscopy. However, optical long baseline interferometry is mandatory to establish the multiplicity of Galactic massive stars at the separation gap between 1 and 50 mas. In this paper, we aim to demonstrate the capability of the new interferometric instrument MIRC-X, located at the CHARA Array, to study the multiplicity of O-type stars and therefore probe the full range of separation for more than 120 massive stars (H<7.5 mag). We initiated a pilot survey of bright O-type stars (H<6.5mag) observable with MIRC-X. We observed 29 O-type stars, including two systems in average atmospheric conditions around a magnitude of H=7.5 mag. We systematically reduced the obtained data with the public reduction pipeline of the instrument. We analyzed the reduced data using the dedicated python software CANDID to detect companions. Out of these 29 systems, we resolved 19 companions in 17 different systems with angular separations between ~0.5 and 50 mas. This results in a multiplicity fraction fm=17/29=0.59+/-0.09, and an average number of companions fc=19/29=0.66+/-0.13. Those results are in agreement with the results of the SMASH+ survey in the Southern Hemisphere. Thirteen of these companions have been resolved for the first time, including the companion responsible for the nonthermal emission in Cyg OB2-5 A and the confirmation of the candidate companion of HD 47129 suggested by SMASH+. A large survey on more than 120 northern O-type stars (H<7.5) is possible with MIRC-X and will be fruitful.

description: This work is devoted to the optimal decay problem for the Euler-Poisson two-fluid system, which is a classical hydrodynamic model arising in semiconductor sciences. By exploring the influence of the electronic field on the dissipative structure, it is first revealed that the \textit{irrotationality} plays a key role such that the two-fluid system has the same dissipative structure as generally hyperbolic systems satisfying the Shizuta-Kawashima condition. The fact inspires us to give a new decay framework which pays less attention on the traditional spectral analysis. Furthermore, various decay estimates of solution and its derivatives of fractional order on the framework of Besov spaces are obtained by time-weighted energy approaches in terms of low-frequency and high-frequency decompositions. As direct consequences, the optimal decay rates of $L^{p}(\mathbb{R}^{3})$-$L^{2}(\mathbb{R}^{3})(1\leq p<2)$ type for the Euler-Poisson two-fluid system are also shown.

description: We present a direct spectroscopic observation of a shallow hydrogen-like muonium state in SrTiO$_3$ which confirms the theoretical prediction that interstitial hydrogen may act as a shallow donor in this material. The formation of this muonium state is temperature dependent and appears below $\sim 70$ K. From the temperature dependence we estimate an activation energy of $\sim 50$ meV in the bulk and $\sim 23$ meV near the free surface. The field and directional dependence of the muonium precession frequencies further supports the shallow impurity state with a rare example of a fully anisotropic hyperfine tensor. From these measurements we determine the strength of the hyperfine interaction and propose that the muon occupies an interstitial site near the face of the oxygen octahedron in SrTiO$_3$. The observed shallow donor state provides new insight for tailoring the electronic and optical properties of SrTiO$_{3}$-based oxide interface systems.

description: Есть ли смысл применять валсартан-сукубитрил при гипертоническом раньше, не дожидаясь появления симптомов СНсФВ? Основной причиной перехода от бессимптомного течения гипертонического сердца к СНсФВ является прогрессирование ДД, связанное с фиброзом миокарда, который, в свою очередь, запускается воспалением коронарных микрососудов. Поскольку СНсФВ характеризуется неблагоприятным прогнозом и для него до сих пор не найдено эффективных средств лечения, основным принципом лечения ГС должно являться недопущение развития СНсФВ.
 Этого можно достичь за счёт поддержания диастолической функции через
 1) нормализацию АД, 2) реверсию ГЛЖ, 3) реверсию фиброза, 4) подавление микрососудистого воспаления. Всеми этими свойствами в большей или меньшей мере обладает препарат валсартан+сукубитрил : он оказывает мощное гипотензивное действие , вызывает реверсию ГЛЖ ; оказывает антифибротический и противовоспалительный эффекты.
 Поскольку для СНсФВ до сих пор не найдено эффективных средств лечения, основным принципом лечения ГС должно являться предотвращение прогрессии диастолической дисфункции, что оправдывает применение валсартан-сукубитрил начиная с ранних/бессимптомных стадий гипертонического сердца

description: Phase fluctuations introduced by the atmosphere are the main limiting factor in attaining diffraction limited performance in extended interferometric arrays at millimeter and submillimeter wavelengths. We report the results of C-PACS, the Combined Array for Research in Millimeter-Wave Astronomy Paired Antenna Calibration System. We present a systematic study of several hundred test observations taken during the 2009-2010 winter observing season where we utilize CARMA's eight 3.5-m antennas to monitor an atmospheric calibrator while simultaneously acquiring science observations with 6.1-m and 10.4-m antennas on baselines ranging from a few hundred meters to ~2 km. We find that C-PACS is systematically successful at improving coherence on long baselines under a variety of atmospheric conditions. We find that the angular separation between the atmospheric calibrator and target source is the most important consideration, with consistently successful phase correction at CARMA requiring a suitable calibrator located $\lesssim$6$^\circ$ away from the science target. We show that cloud cover does not affect the success of C-PACS. We demonstrate C-PACS in typical use by applying it to the observations of the nearby very luminous infrared galaxy Arp 193 in $^{12}$CO(2-1) at a linear resolution of ~70 pc (0.12" x 0.18"), 3 times better than previously published molecular maps of this galaxy. We resolve the molecular disk rotation kinematics and the molecular gas distribution and measure the gas surface densities and masses on 90 pc scales. We find that molecular gas constitutes $\sim30\%$ of the dynamical mass in the inner 700 pc of this object with a surface density $\sim10^4 M_\odot$ pc$^{-2}$; we compare these properties to those of the starburst region of NGC 253.

1. The hypothesis is tested that large daphnids are able to suppress their own and other species' feeding and reproduction by means of excreting an inhibitory chemical (or chemicals).2. In laboratory experiments with an Australian species, Daphnia carinata, water preconditioned with 3–67 daphnids 1-−1 for 30 h had the effect of reducing feeding rates of D. carinata and D. lumholtzi provided with Selenastrum capricornutum.3. For the two Daphnia species, there were highly significant negative correlations between feeding rate and the preconditioning density of D. carinata.4. Water preconditioned with 20–30 daphnids 1-−1 for 1–2 weeks reduced the grazing rates of Daphnia, Moina, and Diaphanosoma 2–3-fold.5. Moina kept in such water for 2 days stopped feeding. Conditioned water kept for 3 days without animals still inhibited grazing by Moina. Hearing to 100°C removed the inhibitory effect.6. Given excess food, and in non-renewed water, a gradient of D. carinata densities developed a strong negative correlation between clutch size and daphnid density after a 6-day time lag. This result may help explain the direct density-dependent regulation of cladoceran reproduction observed earlier in a subtropical lake.

description: Climate variability over the past million years shows a strong glacial-interglacial cycle of ~100,000 years as a combined result of Milankovitch orbital forcing and climatic resonance. It has been suggested that anthropogenic contributions to radiative forcing may extend the length of the present interglacial, but the effects of anthropogenic forcing on the periodicity of glacial-interglacial cycles has received little attention. Here I demonstrate that moderate anthropogenic forcing can act to damp this 100,000 year cycle and reduce climate variability from orbital forcing. Future changes in solar insolation alone will continue to drive a 100,000 year climate cycle over the next million years, but the presence of anthropogenic warming can force the climate into an ice-free state that only weakly responds to orbital forcing. Sufficiently strong anthropogenic forcing that eliminates the glacial-interglacial cycle may serve as an indication of an epoch transition from the Pleistocene to the Anthropocene.

description: Autism is a complex disorder characterized by deficits involving communication, social interaction, and repetitive and restrictive patterns of behavior. Twin studies have shown that autism is strongly heritable, suggesting a strong genetic component. In other disease states with a complex etiology, such as type 2 diabetes, cancer and cardiovascular disease, combined analysis of multiple genetic variants in a genetic score has helped to identify individuals at high risk of disease. Genetic scores are designed to test for association of genetic markers with disease.

description: We present an inelastic neutron scattering study of liquid and solid hydrogen carried out using the wide Angular Range Chopper Spectrometer at Oak Ridge National Laboratory. From the observed dynamic structure factor, we obtained empirical estimates of the molecular mean-squared displacement and average translational kinetic energy. We find that the former quantity increases with temperature, indicating that a combination of thermal and quantum effects is important near the liquid-solid phase transition, contrary to previous measurements. We also find that the kinetic energy drops dramatically upon melting of the crystals, a consequence of the large increase in molar volume together with the Heisenberg indeterminacy principle. Our results are compared with quantum Monte Carlo simulations based on different model potentials. In general, there is good agreement between our findings and theoretical predictions based on the Silvera-Goldman and Buck potentials.

description: Let $A, B$ and $X$ be $n\times n$ matrices such that $A, B$ are positive semidefinite. We present some refinements of the matrix Cauchy-Schwarz inequality by using some integration techniques and various refinements of the Hermite--Hadamard inequality. In particular, we establish the inequality \begin{align*} |||\,|A^{1\over2}XB^{1\over2}|^r|||^2&\leq|||\,|A^{t}XB^{1-s}|^r||| \,\,\,|||\,|A^{1-t}XB^{s}|^r|||\\& \leq\max \{|||\,|AX|^r||| \,\,\,|||\,|XB|^r|||,|||\,|AXB|^r||| \,\,\,|||\,|X|^r|||\}, \end{align*} where $s,t\in[0,1]$ and $r\geq0$.
