description: New construction technologies advocate longer spans and thinner decks for floors. These are conditions that can lead to excessive floor vibrations. A floor has natural vibrations, say 2 Hz. When a rhythmic activity on or near the floor approaches that vibration or a multiple of it, the floor starts to vibrate. This situation can be alleviated by increasing the rate at which a floor absorbs vibration energy, stiffening the floor by increasing the floor member depth, or putting soft springs under vibration-inducing machinery. The implementation of remedial measures depends somewhat on the floor construction.
description: Dans la construction moderne, la mode est aux grandes portées et aux éléments porteurs moins épais pour les planchers. Or, cela peut provoquer une vibration excessive des planchers. Un plancher a des vibrations propres, disons de 2 Hz. Lorsqu'une activité rythmique exercée sur le plancher ou près de celui-ci avoisine ce niveau de vibration, ou un multiple, le plancher se met à vibrer. On peut remédier à ce problème en augmentant la vitesse à laquelle le plancher absorbe l'énergie vibratoire, en renforçant le plancher par augmentation de la hauteur de ses éléments de charpente, ou en montant sur ressorts mous les machines qui produisent des vibrations. La mise en oeuvre des mesures correctives dépend dans une certaine mesure du type de plancher.

description: We propose a new approach leading to giant gain enhancement. It is based on unconventional slow wave resonance associated to a degenerate band edge (DBE) in the dispersion diagram for a special class of photonic crystals supporting two modes at each frequency. We show that the gain enhancement in a Fabry-Perot cavity (FPC) when operating at the DBE is several orders of magnitude stronger when compared to a cavity of the same length made of a standard photonic crystal with a regular band edge (RBE). The giant gain condition is explained by a significant increase in the photon lifetime and in the local density of states. We have demonstrated the existence of DBE operated special cavities that provide for superior gain conditions for solid-state lasers, quantum cascade lasers, traveling wave tubes, and distributed solid state amplifiers. We also report the possibility to achieve low-threshold lasing in FPC with DBE compared to RBE-based lasers.

description: Dynamische Relaxationsvorgänge und insbesondere der damit verbundene dynamische Glasübergang sind wichtige Größen zur Bewertung der Leistungsfähigkeit von Elastomermaterialien, wie sie in Reifen eingesetzt werden. Hierfür kann das Frequenz- und Temperaturverhalten der Relaxationsvorgänge im Elastomer einen Beitrag liefern. Diese Arbeit beschäftigt sich mit der Charakterisierung von Relaxationsvorgängen und dem dynamischen Glasübergang in einem Frequenzbereich von über 10 Dekaden, sowie die Beeinflussung dieser Größen durch die Harze poly-(α-Methylstyrol) (AMS) und poly-(Inden-Cumaron) (IC). Diese Harze haben eine ähnliche Aromatizität, unterscheiden sich jedoch in ihrer molekularen Rigidität. Die Rigidität beeinflusst der Mischbarkeit der Harze in den Elastomermischungen. Als Elastomermischungen werden Silica-gefüllter Styren-Butadien-Kautschuk (SBR) und Butadien-Kautschuk (BR) verwendet. Im Transmissionselektronenmikroskop (TEM) zeigt sich bei beiden Elastomermischungen eine Phasenseparation bei einem Gehalt von 80 phr IC, die bei AMS nicht auftritt. Die Kühlratenabhängigkeit des Glasübergangs ist in der SBR-Mischung stärker, wenn AMS statt IC als Harz verwendet wird. Die Krümmung des Vogel-Fulcher-Tammann-Hesse- (VFTH-) Verlaufs des dynamischen Glasübergangs, die sogenannte Fragilität, ist bei hohen Gehalten an Harz stärker durch AMS als durch IC beeinflusst. Die Messung der Relaxationsvorgänge erfolgt durch breitbandige dielektrische Spektroskopie (BDS) mit Frequenzen von bis zu 2 MHz. Die dielektrisch ermittelte Dynamik des Glasübergangs wird durch Chip-kalorimetrische (FDSC) Messungen mit der Kinetik des Glasübergangs gemäß der Frenkel-Kobeko-Reiner- (FKR-) Hypothese korreliert. Diese Relation zwischen der thermischen Verglasung und der dielektrischen Relaxation wurde erstmalig an Elastomeren untersucht und konnte durch eine einzige Vogel-Fulcher-Tammann-Hesse- (VFTH-) Gleichung beschrieben werden. Die hierfür notwendige Präparation bei Kryo-Mikrotomie und die Kalibration mittels Adamantan für FDSC-Messungen mit Kühlraten bis 1500 K/s wird ebenfalls ausführlich beschrieben.
انضمام در کردی اردلانی : رقابت صرف و نحو

description: این پژوهش به بررسی فرآیند انضمام در کردی اردلانی با تأکید بر بازشناخت ماهیت حوزه ای این فرایند در بستر جدال نظری نحوی - صرفی می پردازد. انضمام اسم یکی از فرآیندهای واژه­سازی است که در صورت متعارف آن موضوع درونی اسمی به هسته فعل واژگانی منضم و سبب تشکیل یک فعل انضمامی می شود. بررسی داده­های زبان کردی، که از پیکره زبان کردی آنلاین دانشگاه کردستان استخراج گردیده است، نشان از آن دارد که رویکرد نحوی نمی­تواند تبیین مناسبی از انضمام اسم در این زبان به دست دهد؛ چرا که در کردی اردلانی می­توان نمونه­هایی از انضمام موضوع بیرونی به فعل را یافت که با مفروضات رویکرد نحوی مغایر است. به طور مشخص، انضمام موضوع بیرونی به فعل برآیند حرکتی تلقی می شود که در آن عنصر حرکت کننده بر رد خود حاکمیت ندارد. بر این اساس، حرکت موضوع بیرونی به سمت فعل «شرط گسترش» اشتقاق های نحوی را نقض می­کند. این شرط کمینه گرایانه در حقیقت بخشی از محدودیت هایی را که در نظریه حاکمیت و مرجع گزینی توسط «اصل محدودیت حرکت هسته» تبیین می یافتند پوشش می دهد. در نتیجه، بر پایه مشاهدات تجربی و مفروض پنداشتن شرط گسترش در اشتقاق سازه های نحوی، واضح است که انضمام اسم به فعل در کردی اردلانی را فرایندی صرفی، و نه نحوی، قلمداد کنیم.\n

Stimulation of surfactant phospholipid biosynthesis in the lungs of rats treated with silica

Year: 1988

description: The effects of intratracheally instilled silica (10 mg/rat) on the biosynthesis of surfactant phospholipids was investigated in the lungs of rats. The sizes of the intracellular and extracellular pools of surfactant phospholipids were measured 7, 14 and 28 days after silica exposure. The ability of lung slices to incorporate [14C]choline and [3H]palmitate into surfactant phosphatidylcholine (PC) and disaturated phosphatidylcholine (DSPC) was also investigated. Both intra- and extra-cellular pools of surfactant phospholipids were increased by silica treatment. The intracellular pool increased linearly over the 28-day time period, ultimately reaching a size 62-fold greater than controls. The extracellular pool also increased, but showed a pattern different from that of the intracellular pool. The extracellular pool increased non-linearly up to 14 days, and then declined. At its maximum, the extracellular pool was increased 16-fold over the control. The ability of lung slices to incorporate phospholipid precursors into surfactant-associated PC and DSPC was elevated at all time periods. The rate of incorporation of [14C]choline into surfactant PC and DSPC was maximal at 14 days and was nearly 3-fold greater than the rate in controls. The rate of incorporation of [3H]palmitate was also maximal at 14 days, approx. 5-fold above controls for PC and 3-fold for DSPC. At this same time point, the microsomal activity of cholinephosphate cytidylyltransferase was increased 4.5-fold above controls, but cytosolic activity was not significantly affected by silica treatment. These data indicate that biosynthesis of surfactant PC is elevated after treatment of lungs with silica and that this increased biosynthesis probably underlies the expansion of the intra- and extra-cellular pools of surfactant phospholipids.

description: Protein C activation by alpha-thrombin on the surface of endothelial cells depends on an essential membrane-glycoprotein cofactor, thrombomodulin. In the present study we have monitored the activity of thrombin-thrombomodulin complexes on human saphenous-vein endothelial cells (HSVEC) or on the endothelial cell line EA.hy 926. Cell monolayers were exposed for 5 min to 8.5 nM human alpha-thrombin and then washed to remove unbound thrombin. The cells were then incubated at 37 degrees C for 5-180 min. At the end of the respective incubation periods, purified human protein C (120 nM) was added in order to assay the activity of the thrombin-thrombomodulin complexes present on the cell surface. HSVEC pre-exposed to thrombin retained their full capacity to promote protein C activation up to 90 min after free thrombin was removed. This capacity then decreased slowly to reach 56% of control value after 180 min of incubation. Original activity was 3.8 +/- 0.9 pmol of activated protein C formed/min per ml per 10(6) cells (mean +/- S.E.M., n = 5). The capacity of protein C activation of EA.hy 926 cells remained constant for 120 min after free thrombin was removed, then decreased to 76% of control after 180 min. Original activity was 2.0 +/- 0.4 pmol of activated protein C formed/min per ml per 10(6) cells (mean +/- S.E.M., n = 3). Similar results were obtained with cells fixed with 3% paraformaldehyde. However, during the 5-180 min incubation period, non-fixed cells of both types were capable of significantly internalizing fluorescent acetylated low-density lipoprotein. In the experimental protocol used here, an eventual inhibition of thrombin internalization by protein C can be excluded, as protein C is only added at the end of the incubation period. We conclude that there is no evidence of rapid internalization of thrombin-thrombomodulin complexes on HSVEC or the EA.hy 926 cell line, as assessed by the ability of membrane-bound thrombin to activate protein C.

description: Background Approximately 20% of adults in the United States experience chronic pain. Integrative Medical Group Visit (IMGV) offers an innovative approach to chronic pain management through training in mindfulness, nutrition, and other mind-body techniques combined with peer support. To date, there are no studies on IMGV implementation, despite its promise as a feasible non-pharmacological intervention for chronic pain management. In this study, we assessed the feasibility of implementing IMGV and assessing its effectiveness for chronic pain. Methods Implementation Mapping was used to develop and evaluate implementation strategies for IMGV. Strategies included disseminating educational materials, conducting ongoing training, and conducting educational meetings. IMGV was delivered by three healthcare providers: an allopathic physician, registered yoga teacher, and naturopathic physician. The effectiveness of IMGV on patient health outcomes was assessed through qualitative interviews and a Patient-Reported Outcomes Scale (PROMIS-29). Provider perspectives of acceptability, appropriateness, and feasibility were assessed through periodic reflections (group interviews reflecting on the process of implementation) and field notes. Paired t-tests were used to assess changes between scores at baseline and post intervention. Qualitative data were coded by three experienced qualitative researchers using thematic content analysis.ResultsOf the initial 16 patients enrolled in research, 12 completed at least two sessions of the IMGV. Other than fatigue, there was no statistically significant difference between the pre- and post-scores. Patients reported high satisfaction with IMGV, noting the development of new skills for self-care and the supportive community of peers. Themes from patient interviews and periodic reflections included the feasibility of virtual delivery, patient perspectives on acceptability, provider perspectives of feasibility and acceptability, ease of recruitment, complexity of referral and scheduling process, balancing medical check-in with group engagement, and nursing staff availability. Conclusions IMGV was feasible, acceptable, and effective from the perspectives of patients and providers. Although statistically significant differences were not observed for most PROMIS measures, qualitative results suggested that participants experienced increased social support and increased pain coping skills. Providers found implementation strategies effective, except for engaging nurses, due to staff being overwhelmed from the pandemic. Lessons learned from this pilot study can inform future research on implementation of IMGV.

description: تغییر و تحول در زبان به عنوان یک پدیده اجتماعی، امری عادی و بدیهی است و سرعت این تغییر و تحول به عوامل متعدد درون زبانی و برون زبانی بستگی دارد. زبان کردی و گویش کرمانجی با وجود مقاومت و سرسختی مردمان کرد در برابر تغییرات فرهنگی و زبانی، همچون زبان فارسی نتوانست در مقابل زبان عربی مصون بماند و با اندکی تاخیر از طریق وام گیری در سه سطح واژگانی، واجی و دستوری، وام گیرنده زبان عربی شد. امروزه کلمات عربی فراوانی در گویش کرمانجی وجود دارند که با وجود انتقال بخشی از آن ها به طور غیر مستقیم و از مسیر زبان فارسی و یا هم­زمان با ورود آن­ها به زبان کردی و فارسی، این واژگان در زبان فارسی کنار گذاشته شده اند، اما در میان کرمانج ها کاربرد دارند. در این مقاله ضمن احصاء نمونه ­هایی از واژگان دخیل پرکاربرد عربی در گویش کرمانجی­ (ارومیه و شهرستان های شمال آذربایجان غربی)، به عوامل ماندگاری این واژگان در گویش کرمانجی نسبت به زبان فارسی و سایر گویش های کردی پرداخته شده است. قرابت دو زبان عربی و کردی کرمانجی از حیث مخارج حروف، پایبندی شدید اکراد نسبت به عناصر فرهنگی، زبانی و دینی و اهتمام ویژه کرمانج­ها به انتقال شفاهی آثار ادبی و داستانی کردی، از جمله عوامل ماندگاری واژگان دخیل عربی در گویش کرمانجی است.\n

description: Enjoying the low maintenance of masonry along with its long-term durability requires that particular attention be paid to those building details that help prevent or divert concentrated flows of water from exterior masonry walls. The careful installation of flashing, overhanging copings or caps, drips, eavestroughs and downspouts, among several other details, can prevent staining, efflorescence, and biological growth on the masonry. Mere unsightliness, one could say. But drenched masonry, given a few freeze-thaw cycles, soon begins to spall, and worse, leads to corrosion of ties. Adieu, long-term durability!
description: Pour profiter de la durabilité et du peu d'entretien que nécessite la maçonnerie, il faut soigner particulièrement les éléments de construction qui empêchent le ruissellement d'eau sur les façades ou le détournent. Solins, couronnements (ou chaperons), larmiers, gouttières et tuyaux de descente sont autant d'éléments qui, parmi d'autres, peuvent empêcher les salissures, les efflorescences et le développement de micro-organismes sur la maçonnerie. Simple préjudice esthétique, pourrait-on dire. Sauf qu'une maçonnerie détrempée qui subit plusieurs cycles gel-dégel commence vite à s'effriter; pire encore, les constituants métalliques des murs peuvent se corroder. Adieu la durabilité!

description: We present the results of observations of asteroid (248370) QN$_{173}$ obtained during July 2021 - January 2022 with three telescopes. Our analysis revealed the presence of the dust tail for about half of a year. The direct images of the asteroid were obtained with broad-band filters. No emissions were revealed in the spectra, and the spectrum of the asteroid closely matched that of a C-type asteroid. Created color and linear polarization variations along the tail were analyzed. The asteroid demonstrated a redder color compared to the Sun. Dramatic changes in dust productivity obtained in different filters were not detected. The $g-r$ color changes from $0.2^{m}$ to $0.7^{m}$ over the coma, and the linear polarization degree varies from about $1.2$\% to $0.2$\% and from $-0.2$\% to $-1.5$\% at the phase angle of $23.2^{\circ}$ and $8.16^{\circ}$. The total dust mass ejected until the latest observation on October 10 is $4.2 \times 10^7$~kg, with a maximum rate of 2.6~kg\,s$^{-1}$ based on the Monte Carlo modeling of the dust tail. The estimated asteroid size is 1.3~km. It is shown that large particles are concentrated around the nucleus, whereas smaller ones dominate in the tail. The evolution of (248370) QN$_{173}$ orbit and the orbits of the sample of the 464 short-periodic comets were followed. Ten of them approached the asteroid's orbit. These objects are not genetically related, despite the very close distance of their orbits for a relatively long time.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: This article introduces the Mathematica package \emph{HEPMath} which provides a number of utilities and algorithms for High Energy Physics computations in Mathematica. Its functionality is similar to packages like FormCalc or FeynCalc, but it takes a more complete and extensible approach to implementing common High Energy Physics notations in the Mathematica language, in particular those related to tensors and index contractions. It also provides a more flexible method for the generation of numerical code which is based on new features for C code generation in Mathematica. In particular it can automatically generate Python extension modules which make the compiled functions callable from Python, thus eliminating the need to write any code in a low-level language like C or Fortran. It also contains seamless interfaces to LHAPDF, FeynArts, and LoopTools.

description: There is a consensus that epigenomic changes play a significant role in carcinogenesis. The effect of DNA methylation and its increased modulations on gene expression during carcinogenesis is significant for diagnostic and therapeutic purposes. Potential phytochemicals as anticancer approach modulators of epigenetic pathways are the focus of this investigation. Molecular docking studies were conducted to foretell how phytochemicals will interact with DNMT3A. As part of our effort to identify novel anti-cancer treatments, we examined a wide variety of phytochemicals from many chemical classes, including cannabinoids, carotenoids, chalcones, fatty acids, lignans, polysaccharides, saponins, steroids, and tannins. The docking scores for Dihydromyricetin are -10.207 kcal/mol, -9.313 kcal/mol for S-Adenosyl-L-methionine (SAM), and -8.757 kcal/mol for Zeylenol were determined to be superior than to phytochemical inhibitors against DNMT3A in the virtual screening method. Docking scores, hydrogen bond interactions, ADME characteristics, and DFT. Molecular Dynamics Simulation and free energy calculations demonstrated that these compounds bind stably to DNMT3A, potentially inhibiting its activity. Network Pharmacology suggested Dihydromyricetin's specific anticancer potential against cervical cancer. These findings provide insights into protein-Ligand interactions with Dnmt3A and highlights the need for In-vitro validation.

description: Two new proteins with apparent molecular masses of 53 kDa and 190 kDa have been identified in both sarcoplasmic reticulum and human blood platelets using a monoclonal antibody, FII1b5. The sarcoplasmic reticulum FII1b5 antigens were present in the terminal cisternae fraction, but were absent from light sarcoplasmic reticulum. The platelet and skeletal muscle proteins were not sensitive to digestion with endoglycosidase H under conditions that removed carbohydrate from the 53 kDa glycoprotein in sarcoplasmic reticulum or GPIIIa in platelet microsomes and did not bind 45Ca in a nitrocellulose overlay calcium-binding assay. These results distinguished the FII1b5 antigens from the 53 kDa glycoprotein and calsequestrin of sarcoplasmic reticulum. The 190 kDa platelet and sarcoplasmic reticulum proteins were extracted from membranes with high concentrations of NaCl, indicating that the high molecular mass FII1b5 antigens are peripherally associated with the bilayers. In contrast, the platelet and muscle 53 kDa proteins remained membrane-bound in the presence of high salt concentrations, suggesting that they are integral proteins.

description: Current approaches to flood management are increasingly insufficient to deal with intensifying flood trends. In this paper, we define and map out the responsibilities and relationships of local, state, and federal governing entities at various levels. We use these relationships to identify gaps in governance needed to address the high financial, human, and infrastructure costs of flooding. This paper offers a description of current flood policies and provides recommendations for innovations in policy solutions to improve governance gaps. We identify three themes from the literature on intergovernmental relations and flood governance: (1) intergovernmental relations (interlinkages and gaps) for flood governance; (2) risks inherent to flood governance (financial, physical, social and individual, and perception of risk); (3) data adequacy and interoperability.

description: The concrete substrate of a deck or slab needs to be carefully prepared for the application of a protective coating or for the replacement of its damaged surface. To ensure that proper bonding can occur, surface contaminants and loose materials have to be removed. This is not an easy task. For one thing, the zones of deteriorated concrete are not always clearly definable; for another, the choice of appropriate preparatory methods is wide, from chemical cleaning to scarifying to blast cleaning. When the surface is dry, clean and level, only then is it ready to receive its topping.

Pour assurer une bonne adhérence, il faut éliminer les contaminants de surface et les morceaux épars. Ce n'est pas chose facile. D'abord, les parties de béton détériorées ne sont pas toujours clairement visibles et puis, le choix des méthodes appropriées de préparation est vaste, depuis le décapage chimique jusqu'au décapage au jet, en passant par l'utilisation de scarificateurs. Lorsque la surface est sèche, propre et plane, on peut alors appliquer le revêtement ou le produit.

Using appropriately defined parameters to describe the evolution of the scalar field energy in this situation, we find that there are two extra fixed points that are not present in the case without curvature. We also analyse the evolution of the effective equation-of-state parameter for different initial values of the curvature.

description: Background Parkinson’s disease (PD) increases the risk of hospitalization and complications while in the hospital. Patient-centered care emphasizes active participation of patients in decision-making and has been found to improve satisfaction with care. Engaging in discussion and capturing hospitalization experience of a person with PD (PwP) and their family care partner (CP) is a critical step toward the development of quality improvement initiatives tailored to the unique hospitalization needs of PD population. Objectives This qualitative study aimed to identify the challenges and opportunities for PD patient-centered care in hospital setting. Methods Focus groups were held with PwPs and CPs to capture first-hand perspectives and generate consensus themes on PD care during hospitalization. A semi-structured guide for focus group discussions included questions about inpatient experiences and interactions with the health system and the clinical team. The data were analyzed using inductive thematic analysis. Results A total of 12 PwPs and 13 CPs participated in seven focus groups. Participants were 52% female and 28% non-white; 84% discussed unplanned hospitalizations. This paper focuses on two specific categories that emerged from the data analysis. The first category explored the impact of PD diagnosis on the hospital experience, specifically during planned and unplanned hospitalizations. The second category delves into the unique needs of PwPs and CPs during hospitalization, which included the importance of proper PD medication management, the need for improved hospital ambulation protocols, and the creation of disability informed hospital environment specific for PD. Conclusion PD diagnosis impacts the care experience, regardless of the reason for hospitalization. While provision of PD medications was a challenge during hospitalization, participants also desired flexibility in ambulation protocols and an environment that accommodated their disability. These findings highlight the importance of integrating the perspectives of PwPs and CPs when targeting patient-centered interventions to improve hospital experiences and outcomes.

description: In order to study particle phagocytosis and glycogenolysis simultaneously, this study was designed to develop a direct-read-out method to monitor Kupffer-cell function continuously, based on the uptake of colloidal carbon by the isolated perfused rat liver. Livers were perfused for 20 min with Krebs-Henseleit buffer saturated with O2/CO2 (19:1). Colloidal carbon (1-2 mg/ml) was added to the buffer, and absorbance of carbon was monitored continuously at 623 nm in the effluent perfusate. Since colloidal-carbon uptake was proportional to A623, rates of uptake were determined from the influent minus effluent concentration difference, the flow rate and the liver wet weight. Rates of colloidal-carbon uptake were 50-200 mg/h per g and were proportional to the concentration of carbon infused. Data from light-microscopy and cell-separation studies demonstrated that carbon was taken up exclusively by non-parenchymal cells and predominantly by Kupffer cells. Further, the amount of colloidal carbon detected histologically in non-parenchymal cells increased as the concentration of colloidal carbon in the perfusate was elevated. When Kupffer cells were activated or inhibited by treatment with endotoxin or methyl palmitate, carbon uptake was increased or decreased respectively. Taken together, these results indicate that Kupffer-cell function can be monitored continuously in a living organ. This new method was utilized to compare the time course of phagocytosis of carbon by Kupffer cells and carbohydrate output by parenchymal cells. Carbohydrate output increased rapidly by 69 +/- 9 mumol per g within 2-4 min after addition of carbon and returned to basal values within 12-16 min. However, carbon uptake by the liver did not reach maximal rates until about 15 min. Infusion of a cyclo-oxygenase inhibitor, aspirin (10 mM), caused a progressive decrease in carbohydrate output and blocked the stimulation by carbon completely. Aspirin neither altered rates of carbon uptake nor prevented stimulation of carbohydrate release by addition of N2-saturated buffer. The data from these experiments are consistent with the hypothesis that output of mediators by Kupffer cells, presumably prostaglandin D2 and E2, occurs transiently as Kupffer cells begin to phagocytose foreign particles in the intact organ, a process which continues at high rates for hours.

description: With concrete block walls, sound insulation is mostly a function of their mass per unit area. With being heavy, such walls -- even single-leaf walls -- usually provide STC ratings of 50±5. (Double-leaf concrete block walls with their greater mass can potentially provide even more sound isolation.) Then sealing the surface of such walls with plaster, block sealer, or just paint, and sound transmission is even further reduced. Attaching gypsum board supported on furring or studs and using sound-absorbing materials can improve sound insulation considerably, depending very much on just how it is done.
description: Dans le cas des murs en blocs de béton, l'isolement acoustique dépend surtout de la masse par unité de surface. Parce qu'ils sont lourds, ces murs - même les simples - présentent habituellement un ITS de 50±5. (Les murs doubles en blocs de béton, qui ont une plus grande masse, peuvent assurer un isolement acoustique encore meilleur.) Appliquez un enduit comme du plâtre ou un protecteur, ou simplement de la peinture, sur la paroi, et la transmission du son est réduite davantage. La pose de plaques de plâtre sur des fourrures ou des poteaux et l'utilisation de matériaux insonorisants peuvent améliorer considérablement l'isolement acoustique, un facteur important étant la manière dont cela est fait.

description: How memories are used by the brain to guide future action is poorly understood. In olfactory associative learning in Drosophila, multiple compartments of the mushroom body act in parallel to assign a valence to a stimulus. Here, we show that appetitive memories stored in different compartments induce different levels of upwind locomotion. Using a photoactivation screen of a new collection of split-GAL4 drivers and EM connectomics, we identified a cluster of neurons postsynaptic to the mushroom body output neurons (MBONs) that can trigger robust upwind steering. These UpWind Neurons (UpWiNs) integrate inhibitory and excitatory synaptic inputs from MBONs of appetitive and aversive memory compartments, respectively. After formation of appetitive memory, UpWiNs acquire enhanced response to reward-predicting odors as the response of the inhibitory presynaptic MBON undergoes depression. Blocking UpWiNs impaired appetitive memory and reduced upwind locomotion during retrieval. Photoactivation of UpWiNs also increased the chance of returning to a location where activation was terminated, suggesting an additional role in olfactory navigation. Thus, our results provide insight into how learned abstract valences are gradually transformed into concrete memory-driven actions through divergent and convergent networks, a neuronal architecture that is commonly found in the vertebrate and invertebrate brains.

description: Among the methods of multiple kernel clustering (MKC), some adopt a neighborhood kernel as the optimal kernel, and some use local base kernels to generate an optimal kernel. However, these two methods are not synthetically combined together to leverage their advantages, which affects the quality of the optimal kernel. Furthermore, most existing MKC methods require a two-step strategy to cluster, i.e., first learn an indicator matrix, then executive clustering. This does not guarantee the optimality of the final results. To overcome the above drawbacks, a one-step clustering with adaptively local kernels and a neighborhood kernel (OSC-ALK-ONK) is proposed in this paper, where the two methods are combined together to produce an optimal kernel. In particular, the neighborhood kernel improves the expression capability of the optimal kernel and enlarges its search range, and local base kernels avoid the redundancy of base kernels and promote their variety. Accordingly, the quality of the optimal kernel is enhanced. Further, a soft block diagonal (BD) regularizer is utilized to encourage the indicator matrix to be BD. It is helpful to obtain explicit clustering results directly and achieve one-step clustering, then overcome the disadvantage of the two-step strategy. In addition, extensive experiments on eight data sets and comparisons with six clustering methods show that OSC-ALK-ONK is effective.

description: Spray deposition and inkjet printing of various nanostructures are emerging complementary methods for creating conductive coatings on different substrates. In comparison to established deposition techniques like vacuum metal coating and lithography-based metallization processes, spray deposition and inkjet printing benefit from significantly simplified equipment. However, there are number of challenges related to peculiar properties and behaviour of nanostructures that require additional studies. In present work, we investigate electroconductive properties and sintering behaviour of thin films produced from nanostructures of different metals (Ag, Cu and Cu-Ag) and different shapes (nanowires and spherical nanoparticles), and compare them to the reference Ag and Cu magnetron deposited films. Synthesized nanostructures were studied with transmission electron microscopy. Morphology and crystallinity of produced metal films were studied with scanning electron microscopy and X-ray diffraction. The electrical parameters were measured by the van der Pauw method. All nanowires-based films provided high conductivity and required only modest thermal treatment (200 C). To achieve sufficient sintering and conductivity of nanoparticles-based films, higher temperatures are required (300 C for Ag nanoparticles and 350 C for Cu and Cu-Ag nanoparticles). Additionally, stability of nanowires was studied by annealing the samples in vacuum conditions inside a scanning electron microscope at 500 C.
