description: Machine learning feature importance calculations are used to determine the molecular substructures that are responsible for mid and far-infrared (IR) emission features of neutral polycyclic aromatic hydrocarbons (PAHs). Using the extended-connectivity fingerprint as a descriptor of chemical structure, a random forest model is trained on the spectra of 14,124 PAHs to evaluate the importance of 10,632 molecular fragments for each band within the range of 2.761 to 1172.745 microns. The accuracy of the results is confirmed by comparing them with previously studied unidentified infrared emission (UIE) bands. The results are summarized in two tables available as Supplementary Data, which can be used as a reference for assessing possible UIE carriers. We demonstrate that the tables can be used to explore the relation between the PAH structure and the spectra by discussing about the IR features of nitrogen-containing PAHs and super-hydrogenated PAHs.

description: Il tessuto muscolare dei pesci è costituito dalla componente carnea che si estende dalla testa alla coda ed è denominato “filetto”. Il muscolo rappresenta la maggior parte della porzione edibile del pesce e la sua proporzione in rapporto al peso totale varia tra il 40% ed il 65% in relazione a specie, forma, età e stato fisiologico dell’animale (Rehbein & Oehlenschläger, 2009). In particolare, i pesci caratterizzati da sezioni trasversali più ellittiche (come tonni, salmoni e aringhe) presentano una maggior proporzione di parte edibile rispetto alle specie piatte o caratterizzate da teste di grandi dimensioni, come la rana pescatrice (Rehbein & Oehlenschläger, 2009). In generale, il tessuto muscolare dei vertebrati è suddiviso in due macrocategorie: il muscolo liscio e il muscolo striato (Robb, 2002). Quest’ultimo, denominato anche scheletrico per via dello stretto legame con il sistema osseo, è incaricato al movimento volontario dell’organismo sotto il controllo del sistema nervoso centrale e periferico (Robb, 2002). Nei pesci la parte edibile, i filetti, è costituita da diversi segmenti paralleli, i miomeri (o miotomi), gruppi di fibre muscolari separati l’un l’altro da guaine di tessuto connettivo di pochi millimetri di spessore noti come miosetti (o miocommi) (Listrat et al., 2016) (Figura 1.1). I miosetti conferiscono continuità strutturale dall’asse vertebrale alla pelle ed il loro ruolo è di garantire la trasmissione delle forze di contrazione della fibra da un miomero all’altro e dallo scheletro alla pelle (Listrat et al., 2016). Questa particolare struttura, con alternanza di muscolo e guaine connettive, è definita organizzazione matematica (Listrat et al., 2016). I miotomi possiedono una forma conica, tipicamente a W, data da un’alternanza tra disposizione posteriore e mediale anteriore dei coni e sono impilati con disposizione matematica su entrambi i lati del setto mediano (Green & Green, 1913). 2 I miomeri anteriori sono caratterizzati da dimensioni maggiori e, grazie a questa caratteristica, la forza generata dalla loro contrazione viene trasmessa a quelli di dimensioni inferiori che vanno verso la coda. Nei pesci ossei il numero di miomeri è quasi sempre uguale al numero delle vertebre e, pertanto, essi possono essere utilizzati per identificare le diverse specie (Listrat et al., 2016).

description: In this review lifetime measurements of ions with at most two electrons are summarized. Such highly ionized systems have been studied - until now - only in the Experimental Storage Ring of the GSI in Darmstadt. Emphasis is put on decays via the weak interaction. The first observations of beta-decay into bound atomic states are described as well as its time mirrored counterpart, the electron-capture decay. In the latter case the decays of hydrogen- and helium-like ions are compared with a surprising result. Further on, the observation of sinusoidal modulations of the decay rate in two-body decays is summarized. As a possible cause an interference due to the emission of neutrinos with different rest mass is discussed.

description: We present new spectral line observations of the CH3CN molecule in the accretion disk around the massive protostar IRAS 20126+4104 with the Submillimeter Array that for the first time measure the disk density, temperature, and rotational velocity with sufficient resolution (0.37", equivalent to ~600 AU) to assess the gravitational stability of the disk through the Toomre-Q parameter. Our observations resolve the central 2000 AU region that shows steeper velocity gradients with increasing upper state energy, indicating an increase in the rotational velocity of the hotter gas nearer the star. Such spin-up motions are characteristics of an accretion flow in a rotationally supported disk. We compare the observed data with synthetic image cubes produced by three-dimensional radiative transfer models describing a thin flared disk in Keplerian motion enveloped within the centrifugal radius of an angular-momentum-conserving accretion flow. Given a luminosity of 1.3x10^4 Lsun, the optimized model gives a disk mass of 1.5 Msun and a radius of 858 AU rotating about a 12.0 Msun protostar with a disk mass accretion rate of 3.9x10^{-5} Msun/yr. Our study finds that, in contrast to some theoretical expectations, the disk is hot and stable to fragmentation with Q > 2.8 at all radii which permits a smooth accretion flow. These results put forward the first constraints on gravitational instabilities in massive protostellar disks, which are closely connected to the formation of companion stars and planetary systems by fragmentation.

description: 4G systems have been continuously evolving to cope with the emerging challenges of human-centric and machine-to- machine (M2M) applications. Research has also now started on 5G systems. Scenarios have been proposed and initial requirements derived. 4G and beyond systems are expected to easily deliver a wide range of human-centric and M2M applications and services in a scalable, elastic, and cost efficient manner. The 3GPP IP multimedia subsystem (IMS) was standardized as the service delivery platform for 3G networks. Unfortunately, it does not meet several requirements for provisioning applications and services in 4G and beyond systems. However, cloudifying it will certainly pave the way for its use as a service delivery platform for 4G and beyond. This article presents a critical overview of the architectures proposed so far for cloudifying the IMS. There are two classes of approaches; the first focuses on the whole IMS system, and the second deals with specific IMS entities. Research directions are also discussed. IMS granularity and a PaaS for the development and management of IMS functional entities are the two key directions we currently foresee.

description: Computer simulations of how drug-releasing stents interact with flowing blood immediately following implantation may improve design of such devices, as well as help predict the outcomes of patients in whom they are implanted, according to a new study by researchers at Emory University . Stents are usually made of metallic scaffolds, and are commonly implanted into heart disease patients, by a procedure called angioplasty, in order to widen narrowed arteries and alleviate symptoms such as chest pain. In recent years there have been a number of important innovations in stent design, including a reduction in the size of the devices, and the development of stents made of absorbent materials that can be coated with drugs. Nevertheless, implantation still carries risks, as it often causes inflammation. Stents also affect the function of blood vessels function by altering their diameter, and blood clots can sometimes form inside them following transplantation. Habib Samady and his colleagues used computational fluid dynamics to generate three-dimensional simulations of how drug-releasing bioresorbable scaffolds interact with vessels and affect blood flow. These devices are designed to release drugs slowly and then dissolve or be absorbed by the tissues surrounding them. The researchers simulated the effects of a stent positioned in various locations of straight and curved blood vessels, focusing on the amount of shear stress the device places on the walls of the vessels, and how this affects blood flow. According to their simulations, the amount of shear stress is highest at the endoluminal strut surface, where the stent comes into contact with the inner lining of the vessels, but very low at the areas where blood flows in and out of the device. At 33% bioresorption of the stent, the picture began to change. The model showed that the amount of stress at the endoluminal surface — where the stent comes into contact with the side of the vessel — is reduced by about one third, but increases by more than 100% at the in-flow and out-flow regions, leading to a more uniform distribution of stress across the device at this stage. The model also revealed that these effects were more pronounced at the inner than the outer curvatures of curved vessels.

description: Most of the suburban residential areas in Germany have been built during the second half of the 20th century. Growing interest among practitioners and scientists is thus paid to the future development of maturing settlement areas characterized by old housing stock and aging inhabitants. This dissertation analyzes processes of change and adaption of suburban residential areas under the conditions of the maturation process. The analysis aims on contributing to the systemic notion of processes changing maturing systems within their natural lifecycle and its interdependence with deliberate adaption under particular stakeholders’ constellations. On the theoretically conceptual level it seeks to explore the key attributes of the development path for evolutionary lifecycles within the context of resilience, discussing the phenomena of stable maturity and continuous adjustment and on the concept of settlement space. By deconstructing the lifecycle concept, the book analyzes the canonical view on mature suburbia based in the traditional growth-maturity-decline pattern and introduces a pluralistic concept of path dependent evolution based on a multi­leveled interdependence between particular levels of space, stakeholders‘ panarchy and adaptive action. On behalf of outcomes based in theory and the results from two empirical studies conducted in German mature suburban residential areas, a concept of multi-leveled ‘systemic space’ as both interpretative and analytic tool for understanding development paths of mature suburban systems is introduced. The results of its application on the case studies show that, especially in terms of homogeneity and diversity, lifecycles of suburban residential areas underlie different conditions for change and adaption during the early and the ­maturity phases, and defines interpretative frames for conceptualizing both theiretical and research approaches. Hereby, it issue the locally based stakeholders’ panarchy as the central adaption-steering potential, putting it at the core of strategic planning interest in mature suburban residential areas.

ICAM-1 Limits Mortality and Viral Titers in the Brains of West Nile Virus NY99 Virus Infected Mice
Creators: name: Philip, Strate
Publisher: name: Georgia State University
Year: 2022

description: To evaluate the role of cell adhesion molecule ICAM-1 in West Nile virus (WNV) infections, an in-vivo murine model was utilized. Wild-type and ICAM-1 deficient mice were infected with the WNV NY99 strain via subcutaneous inoculation in the footpad and assessed for survival and viral titer in the brain. All mice deficient in ICAM-1 reached ethical endpoints by day 10 post infection whereas 40% of wild-type mice survived until the conclusion of the study. Brain homogenates indicated that viral titers were two logs greater in ICAM-1 deficient mice compared to the wild-type. Together, this data suggests that ICAM-1 is critical for mouse survival and limits viral titer in the brain.

description: This thesis aimed to discover factors that affected academic performance and determine if there was any significant change in student performance before the Covid-19 pandemic (Spring, Summer, and Fall 2019) and during the Covid-19 pandemic, specifically the Spring and Fall 2020 semesters. Data was collected from Georgia State University undergraduate biology students who completed three foundational courses: Principles of Biology I, Principles of Biology II, and Molecular Cell Biology. Student resources were identified via survey, while academic performance was measured via iCollege grades and engagement data. Independent samples t-tests comparing the final grades between 2019 and 2020 revealed an increase in grades for Principles of Biology I & II. Spearman correlations revealed a weak positive relationship between grades and engagement data for 2019 and 2020. While student grades increased during the pandemic, the impact on student performance will not be seen until students have completed upper-level courses.

description: The black hole mass and accretion rate in Ultraluminous X-ray sources (ULXs) in external galaxies, whose X-ray luminosities exceed those of the brightest black holes in our Galaxy by hundreds and thousands of times$^{1,2}$, is an unsolved problem. Here we report that all ULXs ever spectroscopically observed have about the same optical spectra apparently of WNL type (late nitrogen Wolf-Rayet stars) or LBV (luminous blue variables) in their hot state, which are very scarce stellar objects. We show that the spectra do not originate from WNL/LBV type donors but from very hot winds from the accretion discs with nearly normal hydrogen content, which have similar physical conditions as the stellar winds from these stars. The optical spectra are similar to that of SS 433, the only known supercritical accretor in our Galaxy$^{3}$, although the ULX spectra indicate a higher wind temperature. Our results suggest that ULXs with X-ray luminosities of $\sim 10^{40}$ erg s$^{-1}$ must constitute a homogeneous class of objects, which most likely have supercritical accretion discs.

description: We apply a number of statistical and machine learning techniques to classify and rank gamma-ray sources from the Third Fermi Large Area Telescope (LAT) Source Catalog (3FGL), according to their likelihood of falling into the two major classes of gamma-ray emitters: pulsars (PSR) or Active Galactic Nuclei (AGN). Using 1904 3FGL sources that have been identified/associated with AGN (1738) and PSR (166), we train (using 70% of our sample) and test (using 30%) our algorithms and find that the best overall accuracy (>96%) is obtained with the Random Forest (RF) technique, while using a logistic regression (LR) algorithm results in only marginally lower accuracy. We apply the same techniques on a sub-sample of 142 known gamma-ray pulsars to classify them into two major subcategories: young (YNG) and millisecond pulsars (MSP). Once more, the RF algorithm has the best overall accuracy (~90%), while a boosted LR analysis comes a close second. We apply our two best models (RF and LR) to the entire 3FGL catalog, providing predictions on the likely nature of {\it unassociated} sources, including the likely type of pulsar (YNG or MSP). We also use our predictions to shed light on the possible nature of some gamma-ray sources with known associations (e.g. binaries, SNR/PWN). Finally, we provide a list of plausible X-ray counterparts for some pulsar candidates, obtained using Swift, Chandra, and XMM. The results of our study will be of interest for both in-depth follow-up searches (e.g. pulsar) at various wavelengths, as well as for broader population studies.

title: Characterization of Zika virus (ZIKV) monoclonal antibodies induced in hamsters
Creators: name: Tang, Mengzhu
Publisher: name: Georgia State University
Year: 2022

description: The Zika virus (ZIKV) has been listed as an international public health emergency since 2016 by the World Health Organization (WHO). Unfortunately, no vaccines or antivirals are currently available for ZIKV prevention and control. The genotypical and phenotypical similarities between ZIKV and other flaviviruses make it challenging to differentiate ZIKV infections among flavivirus infections by serological techniques. One of the approaches to find better ways to unequivocally differentiate ZIKV antibodies from antibodies induced by other serologically cross-reacting flaviviruses was to generate ZIKV-specific monoclonal antibodies (MABs). My thesis focuses on characterizing hamster monoclonal antibodies (MABs), 1) to analyze the activity of the hamster MABs against ZIKV antigens, and 2) to identify specific target epitopes for these MABs recognize. A novel MAB-blocking ELISA (MAB-BE) will be developed and applied to determine the frequency of antibodies against the specific epitopes in a cohort of sera collected from patients in the ZIKV epidemic regions of Colombia.

description: This study employs molecular dynamics simulations to examine the physisorption behavior of hydrocarbon molecules on a covalent graphene-nanotube hybrid nanostructure. The results indicate that the adsorbed molecules undergo self-diffusion into the nanotubes without the need for external driving forces, primarily driven by significant variations in binding energy throughout different regions. Notably, these molecules remain securely trapped within the tubes even at room temperature, thanks to a ``gate'' effect observed at the neck region, despite the presence of a concentration gradient that would typically hinder such trapping. This mechanism of passive mass transport and retention holds implications for the storage and separation of gas molecules.

description: Recent large-scale genomic studies have identified a sodium channel isoform that seems to be responsible for the heart’s ability to conduct electrical impulses. A new review by Thomas Zimmer of Friedrich Schiller University in Germany summarises the new findings, and how they may eventually lead to novel treatments for a variety of life-threatening heart conditions. Voltage-gated sodium channels are barrel-shaped proteins embedded in the membranes of electrically excitable cells, such as neurons and heart muscle. They control the cells’ electrical properties by regulating the inward flow of sodium ions through a central pore. Mammals express nine different sodium channel isoforms, which are made up of multiple subunits, and are largely characterized by their sensitivity to tetrodotoxin (TTX), which can block their function by plugging the pore. Three of these channels — Na 1.5, which is expressed in the heart, and Na 1.8 and Na 1.9, which are expressed by nerve cells — are relatively resistant to TTX, whereas the other six, expressed in skeletal muscle and the central and peripheral nervous systems, are highly sensitive to it. A number of recent genome-wide association studies have shown that the SCN10A gene, which encodes sodium channel Na 1.8, determines the conduction properties of heart cells, even though it is found in relatively low levels in the organ. Mutations in this gene are also associated with Brugada syndrome, a condition that causes heart beats irregularities. “The discovery of Na 1.8 as a relevant player in the heart is another important milestone towards the understanding of cardiac excitability,” says Zimmer. “The actual role [it plays] in the heart remains obscure [but] ongoing research may solve this issue.” Other studies show that Na 1.8 is expressed in neurons in the heart, suggesting that it regulates the electrical activity of these cells. It is also found in heart muscle cells, and SCN10A is now known to also regulate expression of Na 1.5, the most prominent sodium channel in the heart, by interacting with the SCN5A gene. These recent findings suggest that SCN10A/Na 1.8 may be a target that could potentially lead to novel treatments for Brugada syndrome and other related conditions. The next step is to understand how exactly SCN10A exerts its effect, explains Zimmer. “It is important to clarify whether the essential function of SCN10A occurs via regulating SCN5A expression or via the electrophysiological properties of the gene product Na 1.8, and to demonstrate in which cardiac cells of the human heart the channel is expressed,”he adds.

Campodea (Campodea) blandinae ichnusa Condé, 1957: 140.
Remarks
Condé (1956b) quoted several specimens from Sardinian caves as Campodea s. str. A year later, Condé (1957) named them as C. (C.) blandinae ichnusa without any formal description, therefore we suggest that this subspecies should be a nomen nudum.
Habitat and distribution
Cave-adapted species inhabiting caves in the Nebbio and Golo karst regions on Corsica Island (Condé 1948c) and the undescribed subspecies C. (C.) blandinae ichnusa from a cave in Sardinia Island (Condé 1957).

description: Ultrasound (US) is the most commonly used liver imaging modality worldwide. It plays an important role in follow-up of cancer patients with liver metastases. We present an interactive segmentation approach for liver tumors in US acquisitions. Due to the low image quality and the low contrast between the tumors and the surrounding tissue in US images, the segmentation is very challenging. Thus, the clinical practice still relies on manual measurement and outlining of the tumors in the US images. We target this problem by applying an interactive segmentation algorithm to the US data, allowing the user to get real-time feedback of the segmentation results. The algorithm has been developed and tested hand-in-hand by physicians and computer scientists to make sure a future practical usage in a clinical setting is feasible. To cover typical acquisitions from the clinical routine, the approach has been evaluated with dozens of datasets where the tumors are hyperechoic (brighter), hypoechoic (darker) or isoechoic (similar) in comparison to the surrounding liver tissue. Due to the interactive real-time behavior of the approach, it was possible even in difficult cases to find satisfying segmentations of the tumors within seconds and without parameter settings, and the average tumor deviation was only 1.4mm compared with manual measurements. However, the long term goal is to ease the volumetric acquisition of liver tumors in order to evaluate for treatment response. Additional aim is the registration of intraoperative US images via the interactive segmentations to the patient's pre-interventional CT acquisitions.

description: A major challenge in condensed matter physics is active control of quantum phases. Dynamic control with pulsed electromagnetic fields can overcome energetic barriers enabling access to transient or metastable states that are not thermally accessible. Here we demonstrate strain-engineered tuning of La2/3Ca1/3MnO3 into an emergent charge-ordered insulating phase with extreme photo-susceptibility where even a single optical pulse can initiate a transition to a long-lived metastable hidden metallic phase. Comprehensive single-shot pulsed excitation measurements demonstrate that the transition is cooperative and ultrafast, requiring a critical absorbed photon density to activate local charge excitations that mediate magnetic-lattice coupling that, in turn, stabilize the metallic phase. These results reveal that strain engineering can tune emergent functionality towards proximal macroscopic states to enable dynamic ultrafast optical phase switching and control.

description: Background: Recent evidence suggests a merging role of immunothrombosis in the formation of arterial thrombosis. Our study aims to investigate its relevance in stroke patients. Methods: We compared the peripheral immunological profile of stroke patients vs. healthy controls. Serum samples were functionally analyzed for their formation and clearance of Neutrophil-Extracellular-Traps. The composition of retrieved thrombi has been immunologically analyzed. Results: Peripheral blood of stroke patients showed significantly elevated levels of DNAse-I (p < 0.001), LDG (p = 0.003), CD4 (p = 0.005) as well as the pro-inflammatory cytokines IL-17 (p < 0.001), INF-γ (p < 0.001) and IL-22 (p < 0.001) compared to controls, reflecting a TH1/TH17 response. Increased counts of DNAse-I in sera (p = 0.045) and Neutrophil-Extracellular-Traps in thrombi (p = 0.032) have been observed in patients with onset time of symptoms longer than 4,5 h. Lower values of CD66b in thrombi were independently associated with greater improvement of NIHSS after mechanical thrombectomy (p = 0.045). Stroke-derived neutrophils show higher potential for Neutrophil-Extracellular-Traps formation after stimulation and worse resolution under DNAse-I treatment compared to neutrophils derived from healthy individuals. Conclusions: Our data provide new insight in the role of activated neutrophils and Neutrophil-Extracellular-Traps in ischemic stroke. Future larger studies are warranted to further investigate the role of immunothrombosis in the cascades of stroke.

description: High-throughput sequencing of immunoglobulin (Ig) repertoires (Ig-seq) is a powerful method for quantitatively interrogating B cell receptor sequence diversity. When applied to human repertoires, Ig-seq provides insight into fundamental immunological questions, and can be implemented in diagnostic and drug discovery projects. However, a major challenge in Ig-seq is ensuring accuracy, as library preparation protocols and sequencing platforms can introduce substantial errors and bias that compromise immunological interpretation. Here, we have established an approach for performing highly accurate human Ig-seq by combining synthetic standards with a comprehensive error and bias correction pipeline. First, we designed a set of 85 synthetic antibody heavy-chain standards (in vitro transcribed RNA) to assess correction workflow fidelity. Next, we adapted a library preparation protocol that incorporates unique molecular identifiers (UIDs) for error and bias correction which, when applied to the synthetic standards, resulted in highly accurate data. Finally, we performed Ig-seq on purified human circulating B cell subsets (naïve and memory), combined with a cellular replicate sampling strategy. This strategy enabled robust and reliable estimation of key repertoire features such as clonotype diversity, germline segment, and isotype subclass usage, and somatic hypermutation. We anticipate that our standards and error and bias correction pipeline will become a valuable tool for researchers to validate and improve accuracy in human Ig-seq studies, thus leading to potentially new insights and applications in human antibody repertoire profiling.

description: In this publication we consider particle production at a future circular hadron collider with 100 TeV centre of mass energy within the Standard Model, and in particular their QCD aspects. Accurate predictions for these processes pose severe theoretical challenges related to large hierarchies of scales and possible large multiplicities of final state particles. We investigate scaling patterns in multijet-production rates allowing to extrapolate predictions to very high final-state multiplicities. Furthermore, we consider large-area QCD jets and study the expectation for the mean number of subjets to be reconstructed from their constituents and confront these with analytical resummed predictions and with the expectation for boosted hadronic decays of top-quarks and W-bosons. We also discuss the validity of Higgs-Effective-Field-Theory in making predictions for Higgs-boson production in association with jets. Finally, we consider the case of New Physics searches at such a 100 TeV hadron-collider machine and discuss the expectations for corresponding Standard-Model background processes.
