Interpolation graph convolutional network for 3D point cloud analysis

The feature analysis of point clouds, a popular representation of three‐dimensional (3D) objects, is rising as a hot research topic nowadays. Point cloud data bear a sparse and unordered nature, making many commonly used feature extraction methods, for example, Convolutional Neural Networks (CNNs) inapplicable, while previous models suitable for the task are usually complex. We aim to reduce model complexity by reducing the number of parameters while achieving better (or at least comparable) performance. We propose an Interpolation Graph Convolutional Network (IGCN) for extracting features of point clouds. IGCN uses the point cloud graph structure and a specially designed Interpolation Convolution Kernel to mimic the operations of CNN for feature extraction. On the basis of weight postfusion and multilevel‐resolution aggregation, IGCN not only reduces the cost of calculating the interpolation operation but also improves the model's performance. We validate the performance of IGCN on both point cloud classification and segmentation tasks and explore the contribution of each module of our model through ablation experiments. Furthermore, we embed the IGCN point cloud feature extraction module as a plug‐and‐play module into other frameworks and perform point cloud registration experiments.
Does a Multifaceted View of Intellectual Capital Influence the Firm Performance of Readymade Garment Industries in Bangladesh? A Conceptual Analysis

The central construct of this paper is to bring an authentic version of the multifaceted view of intellectual capital (IC) for firm performance through a conceptual framework in the context of Bangladesh's readymade garment (RMG) industries. A company's performance is substantially reliant on the availability of knowledge-related resources, such as IC, in a knowledge-based economy. This paper's methodology emphasizes the theoretical framework connected with IC to demonstrate the research gaps extracted from preceding literature. However, the study's initial outcome is that a plethora of literature considers the traditional three elements (human capital, structural capital, and relational capital) of IC, while little is known about the role of social capital distinctively in Bangladesh. The core conception of the "intellectual capital-based view" proposes that the firm's wealth depends on the divergent perspective of IC, which leads to superior firm Performance. This paper suggests practical guidelines to aid organizations focus on the potential utilization of IC using the conceptual links between knowledge-based assets and organizational performance. The proposed research model may inspire a novel research agenda on how multifaceted IC dimensions are inevitable to foster firm performance, specifically in RMG companies in Bangladesh. The rationale for selecting RMG companies is that this industry requires a comprehensive framework to transition from a labor-intensive to an information-intensive industry. This paper also highlights some ground rules for top management to achieve the maximum benefits of IC and add practical value to the organization.
Scanning probe microscopy of semiconductor quantum dots

The purpose of this study was to design and construct a microscope combining scanning probe and optical microscopy techniques. The microscope is intended for the study of the fluorescence intermittency effect in quantum dots. This microscope has been realised, using quartz tuning forks as the force sensor. Two different techniques for preparing these tuning fork sensors for scanning probe microscopy have been developed, with a quality factor of roughly 104. The microscope operates in high vacuum. Various components have been designed and constructed for this microscope, including positioning devices allowing for the positioning of scanning probe and optical microscopes on the same region of a sample. A time-correlated single photon counting technique has been employed for the optical microscopy part of the microscope.
Morphological and molecular characterization of the genus Coolia (Dinophyceae) from Bahía de La Paz, southwest Gulf of California

The genus Coolia A. Meunier 1919 has a global distribution and is a common member of epiphytic dinoflagellate assemblages in neritic ecosystems. Coolia monotis is the type species of the genus and was the only known species for 76 years. Over the past few decades, molecular characterization has unveiled two species complexes that group morphologically very similar species, so their limits are often unclear. To provide new knowledge on the biogeography and species composition of the genus Coolia, 16 strains were isolated from Bahía de La Paz, Gulf of California. The species were identified by applying morphological and molecular approaches. The morphometric characteristics of all isolated Coolia species were consistent with the original taxa descriptions. Phylogenetic analyses (large subunit [LSU] rDNA D1 / D2 and internal transcribed spacer [ITS] 1 / 5.8S / ITS2) revealed a species assemblage comprising Coolia malayensis, C. palmyrensis, C. tropicalis, and the C. cf. canariensis lineage. This is the first report of Coolia palmyrensis and C. cf. canariensis in Mexico and C. tropicalis in the Gulf of California. Our results strengthen the biogeographical understanding of these potentially harmful epiphytic dinoflagellate species.
Universal orderability of Legendrian isotopy classes

It is shown that non-negative Legendrian isotopy defines a partial order on the universal cover of the Legendrian isotopy class of the fibre of the spherical cotangent bundle of any manifold. This result is applied to Lorentz geometry in the spirit of the authors' earlier work on the Legendrian Low conjecture.
The amount of information stored in proteins and other short biological code sequences

These remarks were made to the conference assembly in a context not unlike that of a surprise witness for the defense. This work was so hot off the press that there had been no time to communicate it before the conference itself. I am grateful to Dr. Lila Gatlin for the opportunity to make this presentation. All of the work to be discussed here has been done in collaboration with A. K. C. Wong, also of the Biotechnology Program at Carnegie-Mellon University. In the last year, we have developed a measure of the amount of information required to perform genetic mutations, together with an algorithm utilizing these measures, for aligning amino acid and RNA code sequences [9], [11]. In the process of this development, we attempted to calculate the amount of information which was stored in a protein's amino acid sequence. We had, at the time, only the tools of the conventional communications form of information theory. Thus, we attempted the calculation using the two expressions:
Komorbiditet ved marginal parodontitis: To sider af samme
sag?

den foreliggende væsentligste viden om sammenhængen mellem marginal parodontitis og en række medicinske sygdomme, herunder hjerte-kar-sygdomme, diabetes mellitus, reumatoid arthritis, osteoporose, Parkinsons sygdom, Alzheimers sygdom, psoriasis og visse lungeinfektioner. Der er i vekslende grad dokumentation for de nævnte sammenhænge især mht. kausalitet, men en række undersøgelser peger på, at parodontalbehandling kan have gunstig effekt på forløbet af iskæmisk hjertesygdom, diabetes, reumatoid arthritis og på risikoen for pneumoni hos særligt udsatte. For de fleste af de nævnte sygdomme skyldes sammenhængen antagelig ligheder i deres inflammatoriske patogenese. Med baggrund i forøget oplysning om den udbredte komorbiditet og de bidirektionelle sygdomsmekanismer bør samarbejdet mellem læger og tandlæger styrkes mhp. optimal behandling af hele patienten med MP. ABSTRACT ABSTRACT Increasing evidence has suggested an independent association between periodontitis and a range of comorbidities, e.g., cardiovascular disease, diabetes, rheumatoid arthritis, osteoporosis, Parkinson’s disease, Alzheimer’s disease, psoriasis, and respiratory infections. Shared inflammatory pathways are likely to contribute to this association, but distinct causal mechanisms remain to be defined. Some of these comorbid conditions may improve by periodontal treatment, and a bidirectional relationship may exist, where, for example, treatment of diabetes can improve periodontal status. The present article presents an over-view of the evidence linking periodontitis with selected systemic diseases and calls for increased cooperation between dentists and medical doctors to provide optimal screening, treatment and prevention of both periodontitis and its comorbidities.
Class Identification, Deferred Elimination, and Social Reproduction in Education: ‘Ontological Ambivalences’ Experienced by Working-Class Students at Elite Universities in China

China’s transition from a redistributive economy to a market economy has created an evolving and intensifying social class structure that requires a class perspective and class analysis tools to capture reconfigured social relations and new patterns of social inequalities. Drawing on a three-year life-story study of working-class students at elite universities in China and working with Bourdieu’s theoretical tools, this article highlights the emotional costs of class mobility and two associated forms of ‘ontological ambivalences’. The findings show ‘mundane reflexivity’ in class struggles against classifications but more importantly, demonstrate the symbolic violence involved therein and indicate the difficulties of individual agency to achieve politically effective resistances. Although based on the specific context of China, this article contributes to reflections on neoliberal policies elsewhere by shedding light on how neoliberalism relates to and enhances class struggles and the significance of adopting a relational class perspective to understand and address social inequalities.
The perivascular niche of endometrial mesenchymal stromal/stem-like cells

Human endometrium is a unique adult tissue that undergoes cyclical shedding, repair, and regeneration during a woman’s reproductive life. Over the past 2 decades, tremendous progress has been made towards the identification and characterization of endometrial stromal stem/progenitor cells . The substantial regeneration of vascularized stroma in the endometrium during the proliferative stages of each menstrual cycle is likely to be mediated by endometrial mesenchymal stromal/stem cells. This review focuses on the perivascular niche for CD140b+CD146+ pericytes and SUSD2+ perivascular cells. The identity, characteristics, and underlying mechanisms of uterine regeneration are also discussed.
Clinical Outcomes and Provoked Epicardial Spasm Phenotypes via Intracoronary Acetylcholine Testing in 680 Patients with Angina and Nonobstructive Coronary Arteries

Abstract Background: Epicardial spasm (ES) phenotypes may be related to the prognosis in patients with coronary spastic angina. Objectives: The purpose of this study was to elucidate the relationship between angiographic coronary vasomotor responses to intracoronary acetylcholine (ACh) injection and prognosis in patients with angina and nonobstructive coronary artery disease (ANOCAD). Methods: This was a retrospective, observational, single-center study of 680 patients with ANOCAD. ACh spasm provocation tests on both coronary arteries were performed without administering nitroglycerine to relieve provoked spasm in a first-attempt artery. ACh was injected in incremental doses of 20/50/100/200 μg into the left coronary artery and 20/50/80 μg into the right coronary artery. Positive ES was defined as ≥90% stenosis and usual chest pain and ischemic ECG changes. Results: Provoked positive ES was observed in 310 patients (46%), including 85 patients (13%) with focal spasm, 150 patients (22%) with diffuse spasm, and 75 patients (11%) with combined spasm (diffuse spasm and focal spasm), whereas the remaining 370 patients (54%) had no provoked spasm. An unclassified ACh test was observed in 186 patients (27%), while 184 patients (27%) had a complete negative ACh test. The clinical outcomes in patients with complete negative ES were satisfactory compared with those with positive ES and unclassified ACh test results. The prognosis in patients with an unclassified ACh test was not different from those with a positive ES. Furthermore, prognosis in patients with ES phenotypes was not different among the three groups. Conclusions: There was no correlation between provoked ES phenotypes via intracoronary ACh testing and prognosis in patients with ANOCAD; however, clinical outcomes in patients with positive ES and unclassified ACh tests were worse compared to those with complete negative ACh tests. We should focus on the treatments in patients with unclassified ACh tests as well as those with ESs.
Electrical Impedance Tomography (EIT) in a Patient Suffering from Post-COVID Syndrome with Dyspnea: A Case Report

Background: Long-term health consequences following COVID-19 disease constitute an increasing problem worldwide. A considerable number of patients still suffer from various symptoms, most commonly dyspnea, months or even years after the acute infection. In these patients, a classical pulmonary function test often yields no significant findings. Subsequently, treating those patients is a challenge for any physician as there are currently no evidence-based treatment plans. Case and methods: We reported the case of a 58-year-old patient who was still suffering from resting dyspnea six months after severe COVID-19 pneumonia. The dyspnea was so pronounced that the patient was supplied with home oxygen, which they used as needed. The regional distribution of ventilation in the lungs was studied twice utilizing noninvasive electrical impedance tomography (EIT). The first examination showed distinct inhomogeneities of regional ventilation, a regional ventilation delay (RVD) of 15%, and pronounced pendelluft phenomena. Seven weeks after treatment with budesonide and physical therapy, the patient reported a clear subjective improvement in complaints. Accordingly, the regional distribution of ventilation also improved. Conclusion: Electrical impedance tomography might be a promising method to assess lung function in post-COVID patients; however, controlled and larger studies are necessary.
Annual Schedule Adjustment by a Long-Distance Migratory Bird

Matching the timing of annual cycle events with the required resources can have crucial consequences for individual fitness. But as the annual cycle is composed of sequential events, a delay at any point may be carried over to the subsequent stage (or more, in a domino effect) and negatively influence individual performance. To investigate how migratory animals navigate their annual schedule and where and when it may be adjusted, we used full annual cycle data on 38 Icelandic whimbrels (Numenius phaeopus islandicus) tracked over 7 years—a subspecies that typically performs long-distance migrations to West Africa. We found that individuals apparently used the wintering sites to compensate for delays that mostly arose as a result of previous successful breeding, and a domino effect was observed from spring departure to laying date, with the potential to affect breeding output. However, the total time saved during all stationary periods is apparently enough to avoid interannual effects between breeding seasons. These findings highlight the importance of preserving good-quality nonbreeding sites in which individuals may adjust annual schedules and avoid potentially adverse effects of arriving late at the breeding grounds.
Increase Butanol Production from Corn Straw by Mineral Compounds Supplementation

In this study, two types of fermentation methods: SSF and consolidation SHF/SSF were used for production of acetone-butanol-ethanol (ABE) from corn straw as a feedstock. Clostridium acetobutylicum DSM1731 was used as the fermenting organism. Corn straw was thermochemically pretreated and then hydrolyzed using three types of enzymes. The impact has been investigated on the effect of mineral compounds supplementation ((NH4)2SO4, MgSO4, (NH4)3PO4) on ABE productivity and butanol content. From the SSF, where mineral salts were supplemented into the fermentation medium, it was found that the maximum ABE and butanol concentrations were 28.35 g/L and 24.03 g/L, respectively, corresponding to a productivities of 0.295 g/L/h (ABE) and 0.250 g/L/h (butanol). In the consolidation SHF/SSF method with mineral compounds supplementation, the maximum ABE and butanol concentrations were 31.35 g/L and 28.64 g/L, respectively, corresponding to productivities of 0.327 g/L/h (ABE) and 0.298 g/L/h (butanol). Compared to control samples, mineral salts supplementation had a positive effect on cellular metabolic activities, leading to an earlier initiation of the solventogenesis stage. In supplemented samples, an increase in the rate of ABE fermentation by Clostridium was observed.
The uniqueness of photometric solutions for spotted W Ursae Majoris binaries

The perturbations frequently affecting the W UMa binaries light curves are currently explained in terms of bright/dark spots appearing on the surface of the components. The localization of these perturbed regions is usually obtained from the study of the light curves in different colors and by means of the so-called light curve synthesis method. The problem of this type of analysis is: i) how far we can trust the solutions and feel confident in their uniqueness, in order to better judge the increasing number of spotted solutions appearing in the literature, ii) in which degree the other system parameters (different from those of the spots) are affected by the incorrect determination of the spots
Observation of interband Berry phase in laser-driven crystals

Ever since its discovery1, the notion of the Berry phase has permeated all branches of physics and plays an important part in a variety of quantum phenomena2. However, so far all its realizations have been based on a continuous evolution of the quantum state, following a cyclic path. Here we introduce and demonstrate a conceptually new manifestation of the Berry phase in light-driven crystals, in which the electronic wavefunction accumulates a geometric phase during a discrete evolution between different bands, while preserving the coherence of the process. We experimentally reveal this phase by using a strong laser field to engineer an internal interferometer, induced during less than one cycle of the driving field, which maps the phase onto the emission of higher-order harmonics. Our work provides an opportunity for the study of geometric phases, leading to a variety of observations in light-driven topological phenomena and attosecond solid-state physics.

On the Comparison of Model-Based Clustering Solutions

In this paper we propose a new similarity index, which can be used to compare model-based clustering solutions. We define also an adjusted-for-chance version, although we advise that, whenever feasible, bootstrap replications should be preferred to chance-corrected similarity indices. We describe the properties of the proposed index and of its chance-corrected version. Finally, we present some applications on simulated and real data.

Tuberculosis of Finger Presenting As Non-healing Ulcer of Digit: A Case Report

Tuberculosis (TB) is a chronic granulomatous infection which most often localises to the respiratory system. Extra-pulmonary tuberculosis is prevalent in immunocompromised individuals, of which cutaneous tuberculosis is exceedingly rare (0.5-2%). Cutaneous TB presents with varied clinical morphologies, either acquired exogenously via direct inoculation on the skin or endogenously due to systemic dissemination. Diagnosis is particularly challenging due to the multitude of differential diagnoses of skin lesions. Microbiological evidence from biopsy and histopathological findings suggestive of granulomatous inflammation are needed to make a definitive diagnosis. Herein we present a rare case of tuberculosis of the finger in a middle-aged man who presented with an ulcerating and erythematous lesion. As cutaneous TB is usually misdiagnosed at the earlier stages, dermatologists and primary care physicians should keep high suspicion for cutaneous TB in any non-healing ulcers which are otherwise unexplained.
Firefly algorithm in optimization of queueing systems

Queueing theory provides methods for analysis of complex service systems in computer systems, communications, transportation networks and manufacturing. It incorporates Markovian systems with exponential service times and a Poisson arrival process. Two queueing systems with losses are also brieﬂy characterized. The article describes ﬁreﬂy algorithm, which is successfully used for optimization of these queueing systems. The results of experiments performed for selected queueing systems have been also presented.
THE INTERPLANETARY NETWORK SUPPLEMENT TO THE HETE-2 GAMMA-RAY BURST CATALOG

Between 2000 November and 2006 May, one or more spacecraft of the interplanetary network (IPN) detected 226 cosmic gamma-ray bursts that were also detected by the French Gamma-Ray Telescope experiment on board the High Energy Transient Experiment 2 spacecraft. During this period, the IPN consisted of up to nine spacecraft, and using triangulation, the localizations of 157 bursts were obtained. We present the IPN localization data on these events.
