Application of New Important Materials

The results of research into new materials are increasingly pushing the boundaries of science and technology. For some of the materials, such as polymers, composites and nanomaterials, new knowledge is expected in the future. However, new knowledge is also being gained in the case of metal alloys, which were considered to have been fully investigated. Thus, in 2018, new knowledge emerged about materials that are believed to be able to significantly influence many areas of modern society. They include seven completely different materials such as polymers, nanocomposites, and metal alloys. The materials are Wood Sponge – the greener way to clean up oceans; the strongest bio-material – stronger than steel and its biodegradable; self-healing material – it does it without external stimulant; Platinum Gold Alloy – matching Diamond in wear resistance; Silicon X – better than the original; Indefinitely recyclable plastics – making a case for the future of plastics; and Glass coating that can block sunlight. In this paper, an overview of knowledge about them is given, and their application characteristics are highlighted.
Experimental Study of Kerf Surface Finish of Abrasive Water-Jet Cutting of Kevlar Fiber-Reinforced Polymers

Machining of difficult-to-process materials, including composite materials, is carried out in cost-effective conditions by resorting to abrasive water jet cutting. The quality of the kerf depends on a large number of input parameters, so that their selection becomes a current problem of real technological interest. Thus, the paper analyzes the cut zones defined by the material removal mechanisms, regarding both their extension and the obtained roughness, through the experimental modeling of the Rz parameter.
Deletion of Xist upstream sequences alters TAD interactions and leads to defects in Xist coating and expression

The topological organization of the genome plays an important role in regulating gene expression. However, the connection between the two remains poorly understood. X-chromosome inactivation is a unique model system to explore the interlink between topologically associated domains (TADs) and gene expression. TADs are largely lost upon X-inactivation, and the inactive-X gets bipartitely reorganized into two large mega domains. However, the X-inactivation center (XIC) harbors two TADs – at the locus of long non-coding RNA Xist (Xist-TAD) and Tsix (Tsix-TAD). Xist is the master regulator of X-inactivation, which coat the inactive-X and facilitates heterochromatinization. Here, we deleted Xist upstream sequences (∼6 kb) near the Xist TAD’s boundary in extraembryonic endoderm stem cells (XEN), which undergo imprinted X-inactivation. This deletion led to the major rearrangement of TADs and affected the expression of genes located within Xist and Tsix TAD, specially the expression of Xist was upregulated, suggesting TADs are essential for proper transcriptional regulation. On the other hand, Xist-upstream deletion on the inactive-X resulted in dispersal of Xist coating and loss of enrichment of repressive chromatin marks on the inactive-X but no effect on X-linked gene silencing. However, we found that autosomal genes were dysregulated in Xist-upstream deleted cells, probably because of misregulation of genes located in Xist and Tsix-TAD, specially Xist. We conclude that Xist upstream sequences are necessary for proper organization of the TADs at the XIC, maintenance of Xist coating/expression and autosomal gene expression.
Repurposing the mammalian RNA-binding protein Musashi-1 1 as an allosteric translation repressor in bacteria

33 The RNA recognition motif (RRM) is the most common RNA-binding protein domain identified in nature. However, RRM-containing proteins are only prevalent in eukaryotic 35 phyla, in which they play central regulatory roles. Here, we engineered an orthogonal post- 36 transcriptional control system of gene expression in the bacterium Escherichia coli with the 37 with 38 neurodevelopmental role that contains two canonical RRMs. In the circuit, Musashi-1 is 39 regulated transcriptionally and works as an allosteric translation repressor thanks to a 40 specific interaction with the leader coding region of a messenger RNA and its structural 41 plasticity to respond to fatty acids. We fully characterized the genetic system at the 42 population and single-cell levels showing a significant fold change in reporter expression, 43 and the underlying molecular mechanism by assessing the in vitro binding kinetics and in 44 vivo functionality of a series of RNA mutants. Moreover, the dynamic response of the 45 system was well recapitulated by a bottom-up mathematical model. This work illustrates 46 how RRM-based regulation can be adapted to simple organisms, thereby paving the way 47 for engineering more complex circuits in prokaryotes by combining transcription and 48 translation control with proteins . 49
Probing sterile neutrinos and axion-like particles from the Galactic halo with eROSITA

The nature of dark matter remains an open question and could be in the form of warm dark matter. Sterile neutrinos and axion-like particles are well motivated warm dark candidates, and can decay into photons, which are consequently detectable by X-ray telescopes with keV dark matter mass. Both particles could explain the observed unidentiﬁed 3.5 keV line and, interestingly, XENON1T observed an excess at a few keV that can originate from axion-like particles. We study the diﬀuse emission coming from the Galactic halo, and test the sensitivity of all-sky X-ray survey eROSITA to identify a sterile neutrino or axion-like particle. By Monte Carlo method, we set bounds on the mixing angle of the sterile neutrinos and coupling strength of the axion-like particles. With eROSITA, we will be able to set stringent constraints, and in particular, we will be able to ﬁrmly probe the best-ﬁt of the unidentiﬁed 3.5 keV line, where we reach an order of magnitude better sensitivity. Moreover, eROSITA is able to conﬁrm an axion-like particle origin of the XENON1T excess for an excess
Hide-n-Sense: Privacy-aware secure mHealth sensing Dartmouth Computer Science Technical Report TR2011-702

As healthcare in many countries faces an aging population and rising costs, mobile sensing technologies promise a new opportunity. Using mobile health (mHealth) sensing, which uses medical sensors to collect data about the patients, and mobile phones to act as a gateway between sensors and electronic health record systems, caregivers can continuously monitor the patients and deliver better care. Furthermore, individuals can become better engaged in monitoring and managing their own health. Although some work on mHealth sensing has addressed security, achieving strong privacy for low-power sensors remains a challenge. We make three contributions. First, we propose an mHealth sensing protocol that provides strong security and privacy properties with low energy overhead, suitable for low-power sensors. The protocol uses three novel techniques: adaptive security, to dynamically modify transmission overhead; MAC striping, to make forgery difficult even for small-sized MACs; and an asymmetric resource requirement. Second, we demonstrate a prototype on a Chronos wrist device, and evaluate it experimentally. Third, we provide a security, privacy, and energy analysis of our system.

Web Content Mining

The World Wide Web, or simply the web, is the most dynamic environment.The web has grown steadly in recent years and his content is changing every day. Today, they are several billions of HTML documents, pictures and another multimedia files available on the Internet. There is a need of methods to help us extract information from the content of web pages. One answer to this problem is using the data mining techniques that is known as web content mining, which is defined as “the process of extracting useful information from the text, images and other forms of content that make up the pages”.
Influences of local and global context on local orientation perception

Visual context modulates perception of local orientation attributes. These spatially very localised effects are considered to correspond to specific excitatory–inhibitory connectivity patterns of early visual areas as V1, creating perceptual tilt repulsion and attraction effects. Here, orientation misperception of small Gabor stimuli was used as a probe of this computational structure by sampling a large spatio‐orientation space to reveal expected asymmetries due to the underlying neuronal processing. Surprisingly, the results showed a regular iso‐orientation pattern of nearby location effects whose reference point was globally modulated by the spatial structure, without any complex interactions between local positions and orientation. This pattern of results was confirmed by the two perceptual parameters of bias and discrimination ability. Furthermore, the response times to stimulus configuration displayed variations that further provided evidence of how multiple early visual stages affect perception of simple stimuli.
Country-level estimates of gross and net carbon fluxes from land use, land-use change and forestry

Abstract. The reduction of CO2 emissions and the enhancement of CO2 removals related to land use are considered essential for future pathways towards net-zero emissions and mitigating climate change. With the growing pressure under global climate treaties, country-level land-use CO2 flux data are becoming increasingly important. So far, country-level estimates are mainly available through official country reports, such as the greenhouse gas inventories reported to the United Nations Framework Convention on Climate Change (UNFCCC). Recently, different modelling approaches, namely dynamic global vegetation models (DGVMs) and bookkeeping models, have moved to higher spatial resolutions, which makes it possible to obtain model-based country-level estimates that are globally consistent in their methodology. To progress towards a largely independent assessment of country reports using models, we analyse the robustness of country-level CO2 flux estimates from different modelling approaches in the period 1950–2021 and compare them with estimates from country reports. Our results highlight the general ability of modelling approaches to estimate land-use CO2 fluxes at the country level and at higher spatial resolution. Modelled land-use CO2 flux estimates generally agree well, but the investigation of multiple DGVMs and bookkeeping models reveals that the robustness of their estimates strongly varies across countries, and substantial uncertainties remain, even for top emitters. Similarly, modelled land-use CO2 flux estimates and country-report-based estimates agree reasonably well in many countries once their differing definitions are accounted for, although differences remain in some other countries. A separate analysis of CO2 emissions and removals from land use using bookkeeping models also shows that historical peaks in net fluxes stem from emission peaks in most countries, whereas the long-term trends are more connected to removal dynamics. The ratio of the net flux to the sum of CO2 emissions and removals from land use (the net-to-gross flux ratio) underlines the spatio-temporal heterogeneity in the drivers of net land-use CO2 flux trends. In many tropical regions, net-to-gross flux ratios of about 50 % are due to much larger emissions than removals; in many temperate countries, ratios close to zero show that emissions and removals largely offset each other. Considering only the net flux thus potentially masks large emissions and removals and the different timescales upon which they act, particularly if averaged over countries or larger regions, highlighting the need for future studies to focus more on the gross fluxes. Data from this study are openly available via the Zenodo portal at https://doi.org/10.5281/zenodo.8144174 (Obermeier et al., 2023).
Spinal Infections: An Update

Spinal infection poses a demanding diagnostic and treatment problem for which a multidisciplinary approach with spine surgeons, radiologists, and infectious disease specialists is required. Infections are usually caused by bacterial microorganisms, although fungal infections can also occur. The most common route for spinal infection is through hematogenous spread of the microorganism from a distant infected area. Most patients with spinal infections diagnosed in early stages can be successfully managed conservatively with antibiotics, bed rest, and spinal braces. In cases of gross or pending instability, progressive neurological deficits, failure of conservative treatment, spinal abscess formation, severe symptoms indicating sepsis, and failure of previous conservative treatment, surgical treatment is required. In either case, close monitoring of the patients with spinal infection with serial neurological examinations and imaging studies is necessary.
Gyro-aided feature tracking for a moving camera: fusion, auto-calibration and GPU implementation

When a camera rotates rapidly or shakes severely, a conventional KLT (Kanade–Lucas–Tomasi) feature tracker becomes vulnerable to large inter-image appearance changes. Tracking fails in the KLT optimization step, mainly due to an inadequate initial condition equal to final image warping in the previous frame. In this paper, we present a gyro-aided feature tracking method that remains robust under fast camera–ego rotation conditions. The knowledge of the camera’s inter-frame rotation, obtained from gyroscopes, provides an improved initial warping condition, which is more likely within the convergence region of the original KLT. Moreover, the use of an eight-degree-of-freedom affine photometric warping model enables the KLT to cope with camera rolling and illumination change in an outdoor setting. For automatic incorporation of sensor measurements, we also propose a novel camera/gyro auto-calibration method which can be applied in an in-situ or on-the-fly fashion. Only a set of feature tracks of natural landmarks is needed in order to simultaneously recover intrinsic and extrinsic parameters for both sensors. We provide a simulation evaluation for our auto-calibration method and demonstrate enhanced tracking performance for real scenes with aid from low-cost microelectromechanical system gyroscopes. To alleviate the heavy computational burden required for high-order warping, our publicly available GPU implementation is discussed for tracker parallelization.
Using Language Models for Flat Text Queries in XML Retrieval

This paper presents a language modeling system for ranking flat text queries against a collection of structured documents. The system, built using Lemur, produces probability estimates that arbitrary document components generated the query. This paper describes storage mechanisms and retrieval algorithms for the evaluation of unstructured queries over XML documents. The paper includes retrieval experiments using a generative language model on the content only topics of the INEX testbed, demonstrating the strengths and flexibility of language modeling to a variety of problems. We also describe index characteristics, running times, and the effectiveness of the retrieval algorithm.

Posterior inferotemporal cortex cells use multiple visual pathways to complement fine and coarse discriminations

6 In the macaque monkey brain, posterior inferior temporal cortex (PIT) cells are responsible 7 for visual object recognition. They receive concurrent inputs from visual areas V4, V3 and V2. We 8 asked how these different anatomical pathways contribute to PIT response properties by 9 deactivating them while monitoring PIT activity. Using cortical cooling of areas V2/V3 or V4 and 10 a hierarchical model of visual recognition, we conclude that these distinct pathways do not 11 transmit different classes of visual features, but serve instead to maintain a balance of localand 12 global-feature selectivity in IT. 13

EFFECT OF INCREASING BODY MASS INDEX ON PREGNANCY OUTCOMES IN NULLIPAROUS WOMEN DELIVERING SINGLETON BABIES

Background: Obesity is a global health problem that is increasing in prevalence. Obesity during pregnancy is considered a high-risk state because it is associated with many complications. This study was conducted to assess the direct relationship of maternal obesity, judged by BMI and its effect on fetomaternal outcome. Materials and Methods: The prospective cohort study was conducted at Department of Obstetrics and Gynaecology, GMSH, Chandigarh. It includes 300 patients (100 in each of the 3 groups, divided on the basis of BMI). The study includes nulliparous pregnant women attending OPD for antenatal care within first trimester of pregnancy. In all the groups, labor and delivery outcomes were studied along with the mode of delivery and fetal outcome. Result: A total of 330 pregnant women were enrolled in our study. In our study group, 6% of the patients of normal BMI had PIH, 34% of Overweight and 41% of Obese had PIH (P<0.001). Significant results were obtained on comparing failed induction, failure of progress of labour, and shoulder dystocia with increasing BMI (p<0.05). In our study, obese patients had statistically significant incidence of PPH with increasing BMI (P=0.002). In our study, results were statistically significant on comparing APGAR scores with increasing BMI (p=0.045). Conclusion: The present study has shown an association between adverse pregnancy outcomes and the increasing BMI of the mother. There was an insignificant increase in intraoperative complications, wound infection, abnormal fetal heart rate patterns with increasing maternal BMI.
The unexpected value of the future

Consider longtermism : the view that the morally best options available to us, in many important practical decisions, are those that provide the greatest improvements in the ( ex ante ) value of the far future. Many (but not all) who accept longtermism do so because they accept an impartial, aggregative theory of moral betterness in conjunction with expected value theory. But such a combination of views results in absurdity if the (impartial, aggregated) value of human-ity’s future is undefined —if, e.g., the probability distribution over possible values of the future resembles the Pasadena game, or a Cauchy distribution. In this paper, I argue that our evidence supports such a probability distribution—indeed, a distribution that cannot be evaluated even by extensions of expected value theory that have so far been proposed. I propose a new method of extending expected value theory, which allows us to deal with this distribution and to salvage the case for longtermism. I also consider how risk-averse decision theories might deal with such a case, and offer a surprising argument in favour of risk aversion in moral decision-making.
ASSESSMENT OF MORPHOMETRIC STUDY OF CALCANEUS AND ITS ARTICULAR FACETS

Background: To assess morphometric study of calcaneus and its articular facets. Materials and Methods: Eighty-six dry calcaneus of both genders were taken and parameters such as type of articular facets, anteroposterior length, transverse diameter, sulcus calcanei length and sulcus calcanei width were recorded. Result: Types of articular facets was A1 in 4, A2 in 4, A3 in 5, A4 in 8, B1 in 20, B2 in 44 and C in 1. The difference was significant (P< 0.05). The mean antero-posterior calcaneus length was 78.2 mm, transverse diameter was 46.3 mm, sulcus calcanei length was 33.4 mm and sulcus calcanei width were 5.9 mm. Conclusion: The most common type of facets on talus are type B. Assessment of morphometric parameters plays key role in reconstruction surgeries and foot rehabilitation procedures.
Neutron diffraction studies under zero and ﬁnite magnetic ﬁelds of the 12 quantum magnetization plateau compound Ni 2 V 2 O 7

We performed powder neutron diffraction experiments on a 12 quantum magnetization plateau compound Ni 2 V 2 O 7 for magnetic ﬁelds in the range 0–10 T. The incommensurate magnetic structures with the propagation vector ( k x ∼ 0 . 45 , 0 , 0) were determined at 0 T and at 6.0 K (between T N1 = 6 . 7 K and T N2 = 5 . 7 K) and 2.3 K. Consequently, the Ni1 and Ni2 moments were disordered and ordered at 6.0 K, respectively, indicating a partially disordered state. The magnetic structure of Ni2 moments was a spin density wave structure with moments ordered parallel to the b axis and perpendicular to the propagation vector. Both Ni1 and Ni2 moments exhibited ellipsoidal cycloidal incommensurate magnetic structures at 2.3 K. These moments lay in the ab plane. The maximum magnitudes of Ni1 and Ni2 moments [1.62(16) and 2.50(6) µ B ] at 2.3 K were sufﬁciently smaller and slightly larger than the value ( ∼ 2 . 2 µ B ) expected from the classical picture. Further, we evaluated the ﬁeld-induced magnetic moments as follows: m 1 = 0 . 3 and m 2 = 1 . 9 µ B at Ni1 and Ni2 sites, respectively, at 10 T and 1.9 K, where the 12 quantum magnetization plateau was observed. The results indicating both the ordered moment at 0 T and the ﬁeld-induced moment at 10 T being small and large at Ni1 and Ni2 sites, respectively, were consistent with results expected in the dimer + monomer model that was proposed by J. J. Cao et al. [Phys. Rev. B 106 , 184409 (2022)].
