Cyanobacterial membrane dynamics in the light of eukaryotic principles
Authors: Siebenaller Carmen , Schneider Dirk
Published: January 2023

Intracellular compartmentalization is a hallmark of eukaryotic cells. Dynamic membrane remodeling, involving membrane fission/fusion events, clearly is crucial for cell viability and function, as well as membrane stabilization and/or repair, e.g., during or after injury. In recent decades, several proteins involved in membrane stabilization and/or dynamic membrane remodeling have been identified and described in eukaryotes. Yet, while typically not having a cellular organization as complex as eukaryotes, also bacteria can contain extra internal membrane systems besides the cytoplasmic membranes (CMs). Thus, also in bacteria mechanisms must have evolved to stabilize membranes and/or trigger dynamic membrane remodeling processes. In fact, in recent years proteins, which were initially defined being eukaryotic inventions, have been recognized also in bacteria, and likely these proteins shape membranes also in these organisms. One example of a complex prokaryotic inner membrane system is the thylakoid membrane (TM) of cyanobacteria, which contains the complexes of the photosynthesis light reaction. Cyanobacteria are evolutionary closely related to chloroplasts, and extensive remodeling of the internal membrane systems has been observed in chloroplasts and cyanobacteria during membrane biogenesis and/or at changing light conditions. We here discuss common principles guiding eukaryotic and prokaryotic membrane dynamics and the proteins involved, with a special focus on the dynamics of the cyanobacterial TMs and CMs.
Set7 methyltransferase roles in myocardial protection from chronic stressors
Authors: Pearson James T.
Published: January 2023

Epigenome changes in chronic states of cardiovascular stress including diabetes, pressure overload and cardiomyopathies frequently involve changes in open chromatin and post-translation modifications of histone lysine residues at specific amino acid positions by acetylation, methylation and phosphorylation. Since the discovery of Set7 as an important regulator of histone H3 lysine 4 methylation state, there has been wide interest in its role in cardiovascular remodeling and cardiac dysfunction. Recent transcriptome and Fourier transform infrared spectroscopy analyses and in vivo assessments of cardiac function by Lunardon and colleagues now reveal a clear role of Set7 in the regulation of the extracellular matrix composition and cardiac hypertrophy in response to chronic isoproterenol induced cardiac stress.
The Effect of Somatosensory Input on Word Recognition in Typical Children and Those With Speech Sound Disorder
Authors: Abu-Zhaya Rana , Goffman Lisa , Brosseau-Lapré Françoise , Roepke Elizabeth , Seidl Amanda
Published: January 2023

Purpose:

Recent work suggests that speech perception is influenced by the somatosensory system and that oral sensorimotor disruption has specific effects on the perception of speech both in infants who have not yet begun to talk and in older children and adults with ample speech production experience; however, we do not know how such disruptions affect children with speech sound disorder (SSD). Response to disruption of would-be articulators during speech perception could reveal how sensorimotor linkages work for both typical and atypical speech and language development. Such linkages are crucial to advancing our knowledge on how both typically developing and atypically developing children produce and perceive speech.

Method:

Using a looking-while-listening task, we explored the impact of a sensorimotor restrictor on the recognition of words whose onsets involve late-developing sounds (s, ʃ) for both children with typical development (TD) and their peers with SSD.

Results:

Children with SSD showed a decrement in performance when they held a restrictor in their mouths during the task, but this was not the case for children with TD. This effect on performance was only observed for the specific speech sounds blocked by the would-be articulators.

Conclusion:

We argue that these findings provide evidence for altered perceptual motor pathways in children with SSD.

Longitudinal Vocal Outcomes and Voice-Related Quality of Life After Selective Bilateral Laryngeal Reinnervation: A Case Study
Authors: Kissel Imke , Van Lierde Kristiane , D'haeseleer Evelien , Adriaansen Anke , Papeleu Tine , Tomassen Peter , Marie Jean-Paul , Meerschman Iris
Published: January 2023

Purpose:

Bilateral vocal fold paralysis (BVFP) is a severe disorder that can result in respiratory, swallowing, and voice-related problems. Most surgical treatments do not restore laryngeal function and often need to compromise voice quality to preserve respiratory function. Laryngeal reinnervation (LR) may offer a solution to this problem, but literature on longitudinal outcomes of this procedure is scarce. This study aims to report the longitudinal vocal outcomes of BVFP after LR and subsequent voice therapy.

Method:

The case of a 23-year-old man with BVFP after a traumatic dissection of both recurrent laryngeal nerves is described. Selective bilateral LR of both adductors and abductors was performed 5 months after the onset of BVFP. Voice therapy was provided after the LR procedure. Multidimensional voice assessments, including acoustic, perceptual, and patient-reported outcome measures (PROMs), were conducted 2, 5, 6.5, 8, and 31 months after LR.

Results:

An improvement of vocal capabilities and voice quality was noticed 6.5 months after LR, after 4.5 months of voice therapy, with normative values after 2.5 years. PROMs showed an improvement of voice-related quality of life, but some limitations to activities of daily living were still present. Inspiratory arytenoid abduction was not observed on laryngeal videostroboscopic findings in this patient, but tracheostomy was not required.

Conclusions:

Voice therapy after LR helps establish healthy and efficient voice use without increasing compensatory hyperfunctional behavior. More research is needed to examine potential merits of voice therapy in the rehabilitation of vocal and respiratory functions after LR.
A H‐type architecture for electric/hybrid‐electric aircraft propulsion systems
Authors: Siddavatam Anil Kumar Reddy , Rajashekara Kaushik , Reddy Ravi Prakash , Huang Hao , Krishnamoorthy Harish S. , Wang Fred
Published: January 2023

In this paper, an H‐type electric/hybrid electric aircraft propulsion architecture is proposed to address the issues associated with the radial electric propulsion architecture. In a radial architecture, a fault on the main bus or failure of the generator leads to shut down of all the propulsion motors in that channel, thus increasing the burden on the remaining motors to maintain the power required by the aeroplane. As a result, it is necessary to oversize the motors for the purpose of compensating for the loss of other motors. To mitigate these issues, a new H‐type architecture is introduced to isolate the particular faulty section while still maintaining power flow to the remaining healthy motors. The proposed architecture minimises the oversizing of various components in the system as compared to radial propulsion architecture. The sizing of components and the amount of overall mass reduction is discussed by using the proposed architecture. Typhoon Hardware in the Loop platform is used to validate the performance of both the architectures for faults at different locations, and the results are presented.
A predictive control method for switching sequence selection based on SVPWM for five‐level converter
Authors: Liu Zhan , Li Bin , Wang Xu , Wu Xiang , Li Fei
Published: January 2023

Aiming at the problems of complex realization, single control target and difficulty in selecting the optimal zero sequence voltage when the traditional space vector PWM (SVPWM) algorithm is adopted in five‐level active neutral‐point‐clamp (5L‐ANPC) converter, a predictive control optimal switching sequence selection (PC‐OSSS) method is proposed. The method adopts the SVPWM control strategy base on the line voltage coordinate and then realizes the selection of optimal switching sequence through the multi‐objective predictive control method. Firstly, the principle of SVPWM based on line voltage coordinate is introduced, and all switching sequences that can be output are obtained. Secondly, the mathematical models of the floating capacitor (FC) voltage, the neutral point (NP) voltage and the common mode (CM) voltage corresponding to each switch sequence are established. Finally, the optimal switch sequence is selected by using the predictive control method based on priority ranking. Compared with traditional SVPWM, the outstanding advantage of this method is that the traditional qualitative comparison method is replaced by quantitative calculation. The multi‐objective control performance of the converter is improved while retaining the advantages of the traditional SVPWM fixed frequency. Finally, the practicability and effectiveness of the proposed control strategy are verified by simulation and experiment.
Absolute Ca II H & K and H-alpha flux measurements of low-mass stars: Extending R′HK to M dwarfs
Authors: Marvin C. J. , Reiners A. , Anglada-Escudé G. , Jeffers S. V. , Boro Saikia S.
Published: January 2023

Context. With the recent surge of planetary surveys focusing on detecting Earth-mass planets around M dwarfs, it is becoming more important to understand chromospheric activity in M dwarfs. Stellar chromospheric calcium emission is typically measured using the R′HK calibrations of Noyes et al. (1984), which are only valid for 0.44 ≤ B – V ≤ 0.82. Measurements of calcium emission for cooler dwarfs B – V ≥ 0.82 are difficult because of their intrinsic dimness in the blue end of the visible spectrum.

Aims. We measure the absolute Ca II H & K and Hα flux of a sample of 110 HARPS M dwarfs and also extend the calibration of R′HK to the M dwarf regime using PHOENIX stellar atmosphere models.

Methods. We normalized a template spectrum with a high signal-to-noise ratio that was obtained by coadding multiple spectra of the same star to a PHOENIX stellar atmosphere model to measure the chromospheric Ca II H & K and Ha flux in physical units. We used three different Teff calibrations and investigated their effect on Ca II H & K and Hα activity measurements. We performed conversions of the Mount Wilson S index to R′HK as a function of effective temperature for the range 2300 K ≤ Teff ≤ 7200 K. Last, we calculated continuum luminosity χ values for Ca II H & K and Hα in the same manner as West & Hawley (2008) for –1.0 ≤ [Fe/H] ≤ + 1.0 in steps of Δ [Fe/H] = 0.5.

Results. We compare different Teff calibrations and find ΔΤeff ~ several 100 K for mid- to late-M dwarfs. Using these different Teff calibrations, we establish a catalog of log R′HK and ℱ′Hα/ℱbol measurements for 110 HARPS M dwarfs. The difference between our results and the calibrations of Noyes et al. (1984) is Δ log R′HK = 0.01 dex for a Sun-like star. Our χ values agree well with those of West & Hawley (2008). We confirm that the lower boundary of chromospheric Ca II H and K activity does not increase toward later-M dwarfs: it either stays constant or decreases, depending on the Teff calibration used. We also confirm that for Ha, the lower boundary of chromospheric flux is in absorption for earlier -M dwarfs and fills into the continuum toward later M dwarfs.

Conclusions. We confirm that we can effectively measure R′HK in M dwarfs using template spectra with a high signal-to-noise ratio. We also conclude that our calibrations are a reliable extension of previous R′HK calibrations, and effective temperature calibration is the main source of error in our activity measurements.

Aims. This work aims to better understand the role of wide brown dwarf companions in planetary systems.

Methods. We obtained high-resolution spectra of six bright stars with co-moving wide substellar companions with the high-resolution SONG, CARMENES, and STELLA spectrographs. We used these spectra to derive radial velocities together with a complete set of physical stellar parameters. We then investigated radial velocity signals and discuss the fraction of planets in such systems. We also re-analysed the ages of our targets, which were used to derive the physical parameters of wide brown dwarf companions. Finally, a compilation of systems with known planets from the literature was considered along with our sample to search for possible peculiarities in their parameter distributions.

Results. Based on the derived ages of six observed systems, we re-computed the masses of the wide companions, confirming their substellar nature. We confirm planets in the HD 3651 and HIP 70849 systems and find a new planetary candidate in the HD 46588 system. In our survey, which is mostly sensitive to Neptune-mass planets at short periods of a few days and Saturn-mass planets at longer periods of hundreds of days, we derived a fraction of planets orbiting stars with wide brown dwarf companions below 70%, with the uncertainties included. Comparing the parameter distributions of our sample with those of single stars, we observe the enhancement of planets with short periods below six days in systems with a wide stellar companion. Finally, planets in systems with wide brown dwarf companions follow their own eccentricity distribution with a maximum at ~0.65 and have periods longer than 40 days, masses higher than 0.1MJ, and eccentricities greater than 0.4.
The MURALES survey

Published: January 2023

This paper is the seventh work in the MUse RAdio Loud Emission lines Snapshot (MURALES) project series, presenting the results of observations obtained with the VLT/MUSE integral field spectrograph of 3C radio sources. Here, we discuss the optical spectral properties of the nuclei of 26 objects with 0.3 < z < 0.82 (median redshift 0.51). At these redshifts, the Hα and [N II] emission lines are not covered by optical spectra and alternative diagnostic diagrams are needed to separate the different spectroscopic sub-classes. We derived a robust spectroscopic classification into high and low-excitation galaxies (HEGs and LEGs) by only using the ratios of emission lines in the rest-frame UV and the blue portion of the spectra. A key result of this study is that FR II LEGs are also found at the highest level of radio power (up to L178 MHz ∼ 2 × 1035 erg s−1 Hz−1), placing them among the most luminous radio sources in the Universe. Furthermore, their fraction within the FR II RG population does not strongly depend on radio luminosity. This suggests that the jet properties in powerful FR II radio sources do not depend on the accretion mode or on the structure of the accretion disk – as would otherwise be expected if the jet launching process were due to the extraction of the rotational energy of the supermassive black hole. The alternative possibility of recurrent transitions between a LEG and a HEG phase is disfavored based on the variation timescales of the various active galactic nucleus (AGN) components.

Aims. We report on the follow-up of the extremely bright long gamma-ray burst (GRB) GRB 210619B with optical polarimetry.

Methods. We conducted optopolarimetric observations of the optical afterglow of GRB 210619B in the SDSS-r band in the time window ∼5967 − 8245 s after the burst, using the RoboPol instrument at the Skinakas observatory.

Results. We report a 5σ detection of polarization P = 1.5 ± 0.3 at polarization angle EVPA = 8 ± 6°. We find that during our observations, the polarization is likely constant. These values have been corrected for polarization induced by the interstellar medium of the Milky Way and host-induced polarization is likely negligible. Thus the polarization we quote is intrinsic to the GRB afterglow.
VST-GAME: Galaxy assembly as a function of mass and environment with VST

Published: January 2023

Context. Observational studies have widely demonstrated that galaxy physical properties are strongly affected by the surrounding environment. On one side, gas inflows provide galaxies with new fuel for star formation. On the other side, the high temperatures and densities of the medium are expected to induce quenching in the star formation. Observations of large structures, in particular filaments at the cluster outskirts (r > 2r200), are currently limited to the low redshift Universe. Deep and wide photometric data, better if combined with spectroscopic redshifts, are required to explore several scenarios on galaxy evolution at intermediate redshift.

Aims. We present a multi-band dataset for the cluster MACS J0416.1-2403 (z = 0.397), observed in the context of the Galaxy Assembly as a function of Mass and Environment with the VLT Survey Telescope (VST-GAME) survey. The project is aimed at gathering deep (r < 24.4) and wide (approx. 20x20 Mpc2) observations at optical (u, ɡ, r, i, VST) wavelengths for six massive galaxy clusters at 0.2 < z < 0.6, complemented with near-infrared data (Y, J, Ks, VISTA, ESO public survey GCAV). The aim is to investigate galaxy evolution in a wide range of stellar masses and environmental conditions. This work describes the photometric analysis of the cluster and the definition of a density field, which will be a key ingredient for further studies on galaxy properties in the cluster outskirts.

Methods. We extracted sources paying particular attention to recovering the faintest ones and simultaneously flagging point sources and sources with photometry affected by artifacts in the images. We combined all the extractions in a multiband catalog that is used to derive photometric redshifts through spectral energy distribution (SED) fitting. We then defined cluster memberships up to 5r200 from the cluster core and measure the density field, comparing galaxy properties in different environments.

Results. We find that the ɡ – r colors show bimodal behaviors in all the environments, but the peak of the distribution of red galaxies shifts toward redder colors with increasing density, and the fraction of galaxies in the blue cloud increases with decreasing density. We also found three overdense regions in the cluster outskirts at r ~ 5r200. Galaxies in these structures have mean densities and luminosities similar to those of the cluster core. The color of galaxies suggests the presence of evolved galaxy populations, an insight into preprocessing phenomena over these substructures. We release the multiband catalog, down to the completeness limit of r < 24.4 mag.
Asteroids’ reflectance from Gaia DR3: Artificial reddening at near-UV wavelengths
Authors: Tinaut-Ruano F. , Tatsumi E. , Tanga P. , de León J. , Delbo M. , De Angeli F. , Morate D. , Licandro J. , Galluccio L.
Published: January 2023

Context. Observational and instrumental difficulties observing small bodies below 0.5 μm make this wavelength range poorly studied compared with the visible and near-infrared. Furthermore, the suitability of many commonly used solar analogues, essential in the computation of asteroid reflectances, is usually assessed only in visible wavelengths, while some of these objects show spectra that are quite different from the spectrum of the Sun at wavelengths below 0.55 μm. Stars HD 28099 (Hyades 64) and HD 186427 (16 Cyg B) are two well-studied solar analogues that instead present spectra that are also very similar to the spectrum of the Sun in the wavelength region between 0.36 and 0.55 μm.

Aims. We aim to assess the suitability in the near-ultraviolet (NUV) region of the solar analogues selected by the team responsible for the asteroid reflectance included in Gaia Data Release 3 (DR3) and to suggest a correction (in the form of multiplicative factors) to be applied to the Gaia DR3 asteroid reflectance spectra to account for the differences with respect to the solar analogue Hyades 64.

Methods. To compute the multiplicative factors, we calculated the ratio between the solar analogues used by Gaia DR3 and Hyades 64, and then we averaged and binned this ratio in the same way as the asteroid spectra in Gaia DR3. We also compared both the original and corrected Gaia asteroid spectra with observational data from the Eight Color Asteroid Survey (ECAS), one UV spectrum obtained with the Hubble Space Telescope (HST) and a set of blue-visible spectra obtained with the 3.6 m Telescopio Nazionale Galileo (TNG). By means of this comparison, we quantified the goodness of the obtained correction.

Results. We find that the solar analogues selected for Gaia DR3 to compute the reflectance spectra of the asteroids of this data release have a systematically redder spectral slope at wavelengths shorter than 0.55 μm than Hyades 64. We find that no correction is needed in the red photometer (RP, between 0.7 and 1 μm), but a correction should be applied at wavelengths below 0.55 μm, that is in the blue photometer (BP). After applying the correction, we find a better agreement between Gaia DR3 spectra, ECAS, HST, and our set of ground-based observations with the TNG.

Conclusions. Correcting the near-UV part of the asteroid reflectance spectra is very important for proper comparisons with laboratory spectra (minerals, meteorite samples, etc.) or to analyse quantitatively the UV absorption (which is particularly important to study hydration in primitive asteroids). The spectral behaviour at wavelengths below 0.5 μm of the selected solar analogues should be fully studied and taken into account for Gaia DR4.
Correlation and sequential path analysis of oil yield and related characteristics in camelina under seasonal variations
Authors: Göre Merve , Zeinalzadeh-Tabrizi Hossein , Kurt Orhan
Published: January 2023

The objectives of the current study were to determine the usefulness of sequential path analysis in camelina to obtain information about the relationship between yield and yield components and to evaluate their relative importance in camelina oil yield under summer and winter cultivation. A split-plot design, with two varieties as the main plot and four sowing times as the subplot, was carried out over two growing seasons (2017–2019) in Samsun, Turkey. Sequential path analysis revealed that, as first-order predictors, grain yield and oil content displayed the most significant and positive direct effects on oil yield in both summer and winter cultivation. The sequential path analysis of second-order variables over the first-order variable revealed that seed number per pod and pod number explained approximately 90% of the variation of the grain yield in summer cultivation and branch number explained approximately 67% of the variation grain yield in winter cultivation. These results indicated that grain yield, as a main predictor of oil yield, had different pathways to affect oil yield in the summer and winter seasons. A higher magnitude of seed number per pod compared to pod number in this study indicated that selecting for higher grain yield can be done indirectly using plants with lower pod number and higher seed number per pod in the summer season. Moreover, branch number was the only trait that had a direct negative effect on grain yield in the winter season, indicating that plants with lower branch number should be selected for higher grain yield. Different environmental factors, including the seasonal cultivation of camelina in this study, were found to be a key factor in improving oil yield and, hence, should be considered as criteria indices in camelina breeding programs in the future.

Published: January 2023

Facing the new round of scientific and technological revolution and industrial transformation, new and higher requirements and challenges are put forward for cultivating the “new generation” of engineering talents. From the perspective of reality and theoretical exploration, the collaboration between the two types of organizations in universities and enterprises in the process of educating people has always lacked theoretical guidance and effective practical paths, and the education reform initiatives of new engineering in recent years also focus on this. Based on synergetic theory, around the core issue of “how to improve the effectiveness of the professional degree training program of industry-education integration”, identify the factors of synergetic Industry-Education Integration, Got the synergetic mode of industry-education integration, further explore the similarity of synergetic mode, so as to provide replicable guidance and countermeasure suggestions for different types of industry-education integration projects.
Der ‚Tabes-Syphilis-Streit‘ Ein Disput über
die Ursache der Tabes dorsalis und der progressiven Paralyse am Ende des 19.
Jahrhunderts
Authors: Steinberg Holger
Published: January 2023

Seit einigen Jahren steigt die Inzidenz der Syphilis und neuroluetischer
Krankheitsbilder. Damit gewinnen auch Tabes dorsalis und progressive Paralyse
wieder an Relevanz in der Neurologie. Um das Verständnis der
Ätiologie dieser Krankheitsbilder wurde in den letzten beiden
Jahrzehnten des 19. Jahrhunderts gerade auch in der deutschen Nervenheilkunde
eine hitzige Debatte geführt, der sogenannte
‚Tabes-Syphilis-Streit‘. Wilhelm Erb hatte 1879 in einem viel
beachteten Vortrag die deutsche Nervenärzteschaft dazu aufgerufen,
endlich zielstrebig die Klärung der Ursache der Tabes dorsalis
anzugehen. Er selbst postulierte v. a. auf Grund von
Krankheitsstatistiken eine vorherige syphilitische Infektion als
hauptsächliches Moment. Die Lösung dieser Frage drängte,
denn der Anteil der Patienten in den psychiatrischen Anstalten, die an
progressiver Paralyse litten, bei der enge Parallelen zur Tabes gesehen wurden,
nahm rapide zu. Die Berliner Nervenärzte Carl Westphal, Ernst Julius
Remak, Martin Bernhardt und Ernst Victor von Leyden empfanden Erbs These als
Fehdehandschuh. Sie sahen die Ursachen von Tabes und progressiver Paralyse in
sozialen Verelendungsprozessen wie feucht-kalten Wohnverhältnissen, in
körperlich einseitigen Arbeitsüberlastungen oder in den
Strapazen von Soldaten im Heer. Als Anlass einer traumatischen Tabes nahmen sie
Erschütterungen oder Prellungen an. Der Leipziger Nervenarzt Paul Julius
Möbius sprach als Erster zwischen 1890 und 1897 aus, dass die einzige
Ursache von Tabes und progressiver Paralyse eine vorherige Syphilis sei.
Konsequent schloss er alle anderen ätiologischen Theorien aus. Vor allem
die bakteriologische und mikrobiologische Forschung der Folgejahre gab
Möbius recht. Somit konnten 40 Jahre nach Erbs Vortrag neben
diagnostischen auch therapeutische Verfahren gezielt entwickelt und angewendet
werden.

Recent studies have demonstrated the close relationship between parathyroid adenoma (PA) and thyroid follicular adenoma (FTA). However, the underlying pathogenesis remains unknown. This study focused on exploring common pathogenic genes, as well as the pathogenesis of these two diseases, through bioinformatics methods. This work obtained PA and FTA datasets from the Integrated Gene Expression Database to identify the common differentially expressed genes (DEGs) of two diseases. The functions of the genes were investigated by GO and KEGG enrichment. The program CytoHubba was used to select the hub genes, while receiver operating characteristic curves were plotted to evaluate the predictive significance of the hub genes. The DGIbd database was used to identify gene-targeted drugs. This work detected a total of 77 DEGs. Enrichment analysis demonstrated that DEGs had activities of 3′,5′-cyclic AMP, and nucleotide phosphodiesterases and were associated with cell proliferation. NOS1, VWF, TGFBR2, CAV1, and MAPK1 were identified as hub genes after verification. The area under the curve of PA and FTA was>0.7, and the hub genes participated in the Relaxin Signaling Pathway, focal adhesion, and other pathways. The construction of the mRNA-miRNA interaction network yielded 11 important miRNAs, while gene-targeting drug prediction identified four targeted drugs with possible effects. This bioinformatics study demonstrated that cell proliferation and tumor suppression and the hub genes co-occurring in PA and FTA, have important effects on the occurrence and progression of two diseases, which make them potential diagnostic biomarkers and therapeutic targets.

Pancreatic cancer (PC) has the lowest survival rate and the highest mortality
rate among all cancers due to lack of effective treatments. The objective of the
current study was to identify potential therapeutic targets in PC. Three
transcriptome datasets, namely GSE62452, GSE46234, and GSE101448, were analyzed
for differentially expressed genes (DEGs) between cancer and normal samples.
Several bioinformatics methods, including functional analysis, pathway
enrichment, hub genes, and drugs were used to screen therapeutic targets for PC.
Fisher’s exact test was used to analyze functional enrichments. To
screen DEGs, the paired t-test was employed. The statistical significance was
considered at p <0.05. Overall, 60 DEGs were detected. Functional
enrichment analysis revealed enrichment of the DEGs in “multicellular
organismal process”, “metabolic process”, “cell
communication”, and “enzyme regulator activity”. Pathway
analysis demonstrated that the DEGs were primarily related to
“Glycolipid metabolism”, “ECM-receptor
interaction”, and “pathways in cancer”. Five hub genes
were examined using the protein-protein interaction (PPI) network. Among these
hub genes, 10 known drugs targeted to the CPA1 gene and CLPS gene were found.
Overall, CPA1 and CLPS genes, as well as candidate drugs, may be useful for PC
in the future.

Published: January 2023

A highly efficient, practical, and ligand-free palladium-catalyzed carbonylation of aryl iodides with alkenylboronic acids has been developed. A variety of chalcones and α-branched enones were isolated in satisfactory to good yields with good substrate compatibilities under an ambient pressure of CO at room temperature. Moreover, the transformation proceeds well in the presence of a substoichiometric amount of base. The merit of this strategy as a late-stage functionalization platform has been demonstrated by modifications of complex substrates derived from estrone and 3-phenyl-l-alanine.

COVID-19 Vaccine-Associated Immune Thrombosis and Thrombocytopenia (VITT): Diagnostic Discrepancies and Global Implications
Authors: Zidan Ali , Noureldin Abdelrahman , Kumar Shreya Anil , Elsebaie Abdelrahman , Othman Maha
Published: January 2023

Vaccine-induced immune thrombotic thrombocytopenia (VITT) has been reported in association with the coronavirus disease 2019 preventative adenovirus vector-based vaccines ChAdOx1 nCoV-19 (Oxford/AstraZeneca) and Ad26.COV2.S (Janssen/Johnson & Johnson) in hundreds of recipients across the globe. VITT is characterized by thrombosis, typically at unusual sites, low fibrinogen, and elevated plasma D-dimer, generally manifesting between 4 and 28 days following vaccination. Detection of anti-platelet factor antibodies using an enzyme-linked immunosorbent assay (ELISA) is often confirmatory. Although several similar principles subside in most diagnostic criteria for VITT, the presentation of a positive ELISA assay, use of expert hematology and neurology opinion, and exclusion of possible VITT cases outside the “standard” 4 to 28-day timeframe have contributed a lack of global standardization for defining VITT. Accordingly, the global and regional incidence of VITT differs according to the diagnostic pathway and case definition used. This has influenced the public perception of VITT's severity and the decision to use adenovirus vector-based vaccines for limiting severe acute respiratory syndrome coronavirus 2 infection. We hereby delineate the recognized pathogenic mechanisms, global incidence, discrepancies in diagnostic criteria, recommended treatments, and global implications to vaccine hesitancy from this coagulopathy.
Recurrent neural networks for dynamical systems: Applications to ordinary differential equations, collective motion, and hydrological modeling

Published: January 2023

Classical methods of solving spatiotemporal dynamical systems include statistical approaches such as autoregressive integrated moving average, which assume linear and stationary relationships between systems’ previous outputs. Development and implementation of linear methods are relatively simple, but they often do not capture non-linear relationships in the data. Thus, artificial neural networks (ANNs) are receiving attention from researchers in analyzing and forecasting dynamical systems. Recurrent neural networks (RNNs), derived from feed-forward ANNs, use internal memory to process variable-length sequences of inputs. This allows RNNs to be applicable for finding solutions for a vast variety of problems in spatiotemporal dynamical systems. Thus, in this paper, we utilize RNNs to treat some specific issues associated with dynamical systems. Specifically, we analyze the performance of RNNs applied to three tasks: reconstruction of correct Lorenz solutions for a system with a formulation error, reconstruction of corrupted collective motion trajectories, and forecasting of streamflow time series possessing spikes, representing three fields, namely, ordinary differential equations, collective motion, and hydrological modeling, respectively. We train and test RNNs uniquely in each task to demonstrate the broad applicability of RNNs in the reconstruction and forecasting the dynamics of dynamical systems.

This paper proposes a design of dual scattering angles multi-path Thomson scattering system with a signal separation function to solve the overlapping phenomenon of scattered light signals and to increase the measurement accuracy for the investigation of anisotropic electron velocity distribution. Furthermore, an optical path design is proposed to demonstrate how overlapping scattered light signals can be separated by setting the optical path in a limited room with a compact layout, which makes the incident interval between two overlapping scattered light signals 1.7 times longer than that of our current system. The specific position of each optical component existing in the system is determined via a Gaussian beam analysis to avoid damage caused by overexpansion of spot size with the application of two cooperating image relay systems. Conversely, a polychromator is optimized by resetting the pass waveband of the interference filter combination to achieve high accuracy in electron temperature (Te) measurement corresponding to two scattering angles simultaneously.

Superconducting nanowire single-photon detectors are an enabling technology for modern quantum information science and are gaining attractiveness for the most demanding photon counting tasks in other fields. Embedding such detectors in photonic integrated circuits enables additional counting capabilities through nanophotonic functionalization. Here, we show how a scalable number of waveguide-integrated superconducting nanowire single-photon detectors can be interfaced with independent fiber optic channels on the same chip. Our plug-and-play detector package is hosted inside a compact and portable closed-cycle cryostat providing cryogenic signal amplification for up to 64 channels. We demonstrate state-of-the-art multi-channel photon counting performance with average system detection efficiency of (40.5 ± 9.4)% and dark count rate of (123 ± 34) Hz for 32 individually addressable detectors at minimal noise-equivalent power of (5.1 ± 1.2) · 10−18 W/Hz. Our detectors achieve timing jitter as low as 26 ps, which increases to (114 ± 17) ps for high-speed multi-channel operation using dedicated time-correlated single photon counting electronics. Our multi-channel single photon receiver offers exciting measurement capabilities for future quantum communication, remote sensing, and imaging applications.
