AN INVESTIGATION OF BED ARMORING PROCESS AND THE FORMATION OF MICROCLUSTERS

Armoring is a recognized phenomenon in gravel bed rivers that have been subject to periods of extended low flows. Coarsening creates a bed surface where greater intergranular friction angles increase the surface stability and the stress necessary to entrain the bed. We will present results from a series of flume experiments investigating the processes of bed armoring and microcluster formation with the purpose of quantifying the change in overall bed stability. Where a gravel bed river incorporates structure in its bed surface, overall bed stability increases. This structure forms a microtopography that increases the roughness of the bed. Microclusters, or discrete particle groupings on the bed surface, are common features in surface microtopography. The influence and interaction of the sediment grains and channel flow hydraulics during the armoring process has yet to be fully defined. Recent research on microclusters has focused on how the turbulent flow field is affected by their presence. Where 2D flow fields have been measured, the results point to a strong 3D component to turbulence around microforms, which has not been fully elucidated. The flume experiments presented here are designed to quantify the influence of independent variables over bed armoring, link the bed armoring process to the occurrence and distribution of microclusters on the armored bed, and measure the stability of the final, armored beds. The flume experiments created armored beds testing 4 sediment mixtures against 4 flow rates. The microcluster density on each bed is measured through the creation of DEMs from laser profile scans of the bed surface. Acoustic Doppler Velocimeters measure 3D point velocities over the armored bed and around microcluster groups of varying densities. The effect of bed substrate grain size distributions and flow rate during armor layer formation is linked to the creation of structure in the armor layer topography. Continued data analyses will compute the shear stresses associated with each of the armored bed surfaces. The bed surface mediates interaction between the flow and the bed sediments and determines the sediment available for transport. It also defines the habitat for aquatic insects, salmonid spawning, and juvenile fish. The formation of rough topography on the bed surface creates areas of variable flow with the regions directly downstream of large clasts acting as a refuge for aquatic organisms. When the armor layer breaks, the channel bed erodes and incision may occur. This may negatively impact aquatic life in the channel that is dependent on stability of the bed surface. An improved understanding of armored channel bed formation and stability will aid predictions of the effect of controlled flow releases on the downstream channel morphology.
Cryptanalysis of the Peregrine Lattice-Based Signature Scheme

The P EREGRINE signature scheme is one of the candidates in the ongoing Korean post-quantum cryptography competition. It is proposed as a high-speed variant of F ALCON , which is a hash-and-sign signature scheme over NTRU lattices and one of the schemes selected by NIST for standardization. To this end, P EREGRINE replaces the lattice Gaussian sampler in the F ALCON signing procedure with a new sampler based on the centered binomial distribution. While this modiﬁcation offers signiﬁ-cant advantages in terms of efﬁciency and implementation, it does not come with a provable guarantee that signatures do not leak information about the signing key. Unfortunately, lattice-based signature schemes in the hash-and-sign paradigm that lack such a guarantee (such as GGH, NTRUSign or DRS) have generally proved insecure. In this paper, we show that P EREGRINE is no exception, by demonstrating a practical key recovery attack against it. We observe that the distribution of P EREGRINE signatures is a hidden transformation of some public distribution and still leaks information about the signing key. By adapting the parallelepiped-learning technique of Nguyen and Regev (Eurocrypt 2006), we show that the signing key can be recovered from a relatively small number of signatures. The learning technique alone yields an approximate version of the key, from which we can recover the exact key using a decoding technique due to Thomas Prest (PKC 2023). For the reference implementation (resp. the ofﬁcial speciﬁcation version) of P EREGRINE –512, we fully recover the secret key with good probability in a few hours given around 25,000 (resp. 11 million) signature samples.
LncRNA PART1 promotes malignant biological behaviors associated with head and neck cancer cells by synergistic action with FUT6

The aim of this study was to determine the role of lncRNA PART1 in migration, proliferation, and apoptosis in head and neck cancer (HNC) cell lines and its relationship with FUT6 in tumorigenesis and progression. Bioinformatics analysis and qRT ‒ PCR showed that lncRNA PART1 was expressed at low levels in HNC. The results of proliferation, apoptosis, migration and �ow cytometry showed that the low expression of lncRNA PART1 inhibited the apoptosis of HN4 cells and promoted the migration and proliferation of HN4 cells. Through bioinformatics analysis, FUT6 was found to be expressed at low levels in HNC and correlated with patient survival. Immunohistochemical, qRT-PCR results showed that FUT6 was underexpressed in tumor tissues and HN4 cells. Cell and animal experiments showed that overexpression of FUT6 could inhibit tumor proliferation and migration. Bioinformatics analysis showed that lncRNA PART1 was positively correlated with FUT6. By qRT ‒ PCR, we observed that after knockdown of lncRNA PART1, both the mRNA and protein expression levels of FUT6 were reduced. The above results indicated that lncRNA PART1 and FUT6 were poorly expressed in HNC and that lncRNA PART1 affected the development of cancer by interacting with FUT6.
Explorer What do character-level models learn about morphology? The case of dependency parsing

When parsing morphologically-rich languages with neural models, it is bene ﬁ cial to model input at the character level, and it has been claimed that this is because character-level models learn morphology. We test these claims by comparing character-level models to an oracle with access to explicit morphological analysis on twelve languages with varying morphological typologies. Our results high-light many strengths of character-level models, but also show that they are poor at disam-biguating some words, particularly in the face of case syncretism. We then demonstrate that explicitly modeling morphological case improves our best model, showing that character-level models can bene ﬁ t from targeted forms of explicit morphological modeling.
On characterising surface topography of metal powder bed fusion additive manufactured parts

Inherent to the somewhat uncontrolled nature of the additive process, the surfaces of metal powder bed fusion additively manufactured components tend to be very rough. Large isolated ‘bumps’, as one of the major defect features, are often present due to partially melted particles attached to the surface. An enhanced watershed segmentation method is proposed to separate these ‘bump’ features from the underlying surface texture such that the ‘bumps’ and underlying surface can be quantitatively analysed. The results show that the amplitude roughness parameters of the underlying surface are significantly less than the un-segmented surface and spatial roughness parameters differ between two surfaces. Characterising the extracted underlying surface and ‘bumps’ independently allows better correlation between surface measurements and additive system performance and hence aids in process optimization.

Surface heat fluxes from Lake Ontario: Further verification of lake thermal model

The components of heat flux at the surface of Lake Ontario during the stratified season of 1972 are estimated using a lake thermal model, which has previously been verified with respect to temperature simulation. The model inputs are lake geometry and optical properties and surface weather observations. The heat flux components are compared with independent observationally based estimates. The net flux is simulated accurately by the model; the radiative input to the lake is significantly overestimated. The error in the radiative flux is traced to the expression accounting for the effect of cloud cover on insolation. This error leads to compensating errors in sensible and latent heat fluxes, resulting in accurate simulation of the net heat flux. Evaporation rates estimated by the model are approximately 50% higher than other estimates. The use of observed insolation, or a more accurate formula for the effect of clouds, would probably lead to accurate simulation of evaporation rates.
Mechanisms of Global Ocean Ventilation Age Change during the Last Deglaciation

Marine radiocarbon ( 14 C) is widely used to trace deep ocean circulation, providing insight into the atmosphere-10 ocean exchange of CO2 during the last deglaciation. Using two transient simulations with tracers of 14 C and ideal age, we found that the oldest ventilation age is not observed at the Last Glacial Maximum (LGM). In contrast, the model shows a modestly younger ventilation age during the LGM compared to present day, mainly due to a stronger glacial Antarctic Bottom Water (AABW) transport associated with sea ice expansion. Notably, the ocean ventilation age is significantly older around 14-12 ka compared to the age at the LGM, with deep Pacific waters playing a predominant role, primarily caused by 15 the weakening of AABW transport.
Single-shot lamina thoracic paravertebral block with ketofol for modified radical mastectomy

We describe the use of single-shot lamina thoracic paravertebral block (TPVB) with sedation for a 56-year-old female patient who had modified radical mastectomy with axillary clearance. Two years ago, she suffered vocal cord palsy post thyroidectomy, which was managed with tracheostomy. The tracheostomy tube was removed 8 months later, leaving the patient with persistent hoarseness of voice and left vocal cord palsy. She declined general anesthesia and consented for TPVB. The surgery lasted 95 minutes and was successfully completed with TPVB. Her vital signs were stable during the operation. She had low pain scores, minimal opioid use, early alimentation, and no postoperative nausea and vomiting and was discharged early. We present the anesthetic management of this case in our setting, where TPVB under ultrasound guidance and modern drug-delivery systems for sedation are unavailable.

Objective: Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. Methods: Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. Results: Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. Conclusion: This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

The performances of an original passive control system based on a biomimetic approach are assessed by investigating the ﬂow over a bluff body. This control device consists of a couple of ﬂaps made from the combination of a rigid plastic skeleton coated with a porous fabric mimicking the shaft and the vane of the bird’s feathers, respectively. The sides of a square cylinder have been ﬁtted with this system so that each ﬂap can freely rotate around its leading edge. This feature allows the movable ﬂaps to self-adapt to the ﬂow conditions. Comparing both the uncontrolled and the controlled ﬂow, a signiﬁcant drag reduction ( ≈ 22% on average) has been obtained over a broad range of Reynolds numbers. This improvement is related to the increase of the base pressure in the controlled case. The investigation of the mean ﬂow reveals a noticeable modiﬁcation of the ﬂow topology at large scale in the vicinity of the controlled cylinder. Meanwhile, the study of the relative motion of both ﬂaps highlights that their dynamics is sensitive to the Reynolds number. Furthermore, the analysis of the ﬂow dynamics at large scale suggests a lock-in coupling between the ﬂap motion and the vortex shedding.

Reynolds Stress and Turbulent Energy Production in a Tidal Channel

Abstract A high-frequency (1.2 MHz) acoustic Doppler current profiler (ADCP) moored on the seabed has been used to observe the mean and turbulent flow components in a narrow tidally energetic channel over six tidal cycles at neap and spring tides. The Reynolds stress has been estimated from the difference in variance between the along-beam velocities of opposing acoustic beams with a correction for the sampling scheme and bin size. Shear stress was found to vary regularly with the predominantly semidiurnal tidal flow with the stresses on the spring ebb flow (up to 4.5 Pa) being generally greater than on the flood flow (<2 Pa) when the currents are weaker. The vertical structure approximated to linear stress profiles decreasing from maximum values near the bed to almost zero stresses just below the surface. The variation in the bed stress was well represented by a quadratic drag law, based on the depth-mean current, with an estimated drag coefficient of 2.6 ± 0.2 × 10−3.

Molecular and Clinical Pro�le of patients referred as Noonan or Noonan-like Syndrome in Greece: a cohort of 86 patients

Noonan syndrome (NS) is an autosomal dominant disorder characterized by clinical and genetic heterogeneity. It belongs to a wider group of pathologies, Rasopathies, due to the implication of mutations in genes encoding components of the Ras/MAPK signalling pathway. Recording the genetic alterations across populations helps assessing speci�c features to speci�c genes which is essential for better disease’s recognition, prognosis and monitoring. Herein, we report the clinical and molecular data of a Greek cohort comprising of 86 NS or NS-like patients admitted at a single tertiary Centre in Athens, Greece. The analysis was performed using Sanger and Next-Generation-Sequencing, comprising 14 different genes. The mutational rates of the con�rmed NS-associated genes in the Greek NS population are: PTPN11 32.5%; RIT1 5.8%; SOS1 4.7%; BRAF 1.2%; CBL 1.2%; KRAS 1.2%; MAP2K1 1.2%; RAF1 1.2%; SHOC2 1.2%, corresponding to 50% of positivity in total NS population. The genotype-phenotype analysis showed statistically signi�cant differences regarding craniofacial dysmorphisms (p=0.005) and pulmonary valve stenosis (PS) (p<0.001) between patients harboring a mutation in any of the tested genes and mutation-free patients. Patients with at least one mutation had 6.71 times greater odds to develop PS compared to mutation-negative patients [OR=6.71, 95%; CI= (2.61, 17.27)]. PTPN11 positive patients showed higher frequency of epicanthal folds (p=0.004), ptosis (p=0.001) and coarseness (p=0.001) and lower frequency of neurological �ndings (p=0.006) , compared to patients with carrying mutations in other genes. Conclusion: Craniofacial dysmorphismand PS prevail among mutation positive compared to mutation negative NS and NS-like patients while neurological defects
The confrontation of robots and the challenges facing arti�cial intelligence

Arti�cial intelligence is the knowledge of knowing and designing intelligent agents, although the topic of arti�cial intelligence is very attractive, its challenges are equally important. The dangers of a robot's wrong decisions in confronting humans or two robots and other problems of wrong decisions by robots have been the concern of many scientists in this �eld. In this article, we have presented a solution to the mentioned problems using the Hyper Move Theory (HMT) method and in the form of an example.

Liver cirrhosis is a leading cause of death in Hispanics and Hispanics who live in South Texas have the highest incidence of liver cancer in the United States. We aimed at determining the prevalence and associated risk factors of cirrhosis in this population. Clinical and demographic variables were extracted for 2466 participants in the community-based Cameron County Hispanic Cohort in South Texas. Aspartate transaminase to Platelet Ratio Index (APRI) was used to predict cirrhosis in Cameron County Hispanic Cohort. The prevalence of cirrhosis using APRI (cid:1) 2 was 0.94%, which is nearly 4-fold higher than the national prevalence. Using APRI (cid:1) 1,
Epidermal Nevus Syndrome: Mr of Intracranial Involvement

Focal thickening of the calvarium, hypoplasia of the white matter, cortical calcifications, and a leptomeningeal drape that enhanced after contrast injection were demonstrated by MR in the parietooccipital region ipsilateral to a facial sebaceous nevus in a patient with epidermal nevus syndrome. Epidermal nevus syndrome (ENS), or nevus linearis sebaceous, is a rare congenital neurocu-taneous disorder characterized by the association of epidermal nevi of different types with other developmental defects of the central nervous system , eye, and skeleton (1). Central nervous system anomalies are found predominantly in patients with epidermal nevi on the head and are usually ipsilateral to the skin lesion (2). Mental retardation, seizures, and focal neurologic deficits are the most common clinical features (2). We found one patient with ENS studied with unenhanced magnetic resonance (MR) imaging reported in the literature (3). Herein we report pre-and postcontrast MR findings with computed tomographic (CT) correlations in a patient with ENS. An 18-year-old woman with a diagnosis of ENS underwent a cranial MR examination at 0.5 T because of transient worsening of a congenital right hemiparesis associated with frontal headache. At birth clusters of yellow nodules showing granular surfaces pitted with hypertrophic sebaceous glands consistent with Jadassohn sebaceous nevus were present in the left frontomaxillary region of the face; they were associated with alopecia in the left temporoparietal region. A mild right-sided hemiparesis was also noted. Ocular abnormalities included bilateral retinal depigmentation and co-loboma of the head of the left optic nerve. A biopsy at 3 months of age confirmed that the facial nevi were the sebaceous type. A febrile convulsion on the right side occurred at 9 months of age, and two generalized seizures occurred when the patient was 2 years old. Neurologic examination at the time of MR revealed hypoplasia of the right side of the body with ipsilateral mild spastic paresis and moderate global mental retardation. On MR the right cerebral hemisphere was noted to be larger than the left, and there was focal thickening of the left parietal bone (Fig lA). A subarachnoid cyst at the pole of the left temporal lobe and widening of the left Sylvian fissure were also present (not shown). The white matter of the left parietal and occipital lobes was hypoplastic, with enlargement of the trigone and the occipital horn of the left lateral ventricle (Fig 1 A-1 F). The overlying cortex was covered by a 0.5-to 1.5-cm-thick "drape" …
