Feature extraction and segmentation of pavement distress using an improved hybrid task cascade network

ABSTRACT An improved Hybrid Task Cascade (HTC) instance segmentation model was proposed to segment pavement surface distress intelligently and accurately. First, the automatic color equalization (ACE) algorithm was performed to preprocess the dataset. Then, HTC and the proposed HTC were described. The proposed HTC was modified using the ResNeXt101 network, balanced feature pyramid (BFP) and deformable convolution (DCN). The Soft non-maximum suppression method (Soft-NMS) and balanced L1 loss were used to supplement the above work. Finally, the average detection precision (AP) and the segmentation AP indexes were assessed by comparison and contrast. Experimental results demonstrated that the original HTC has crack miss detection and false detection problems. In contrast, the improved HTC has a recall rate as high as 96.1%, indicating a low miss-detection rate. Compared with other mainstream instance segmentation models, the improved HTC still leads in various indicators on our or public datasets. Comparisons between the predicted and true distress areas were analysed, the relative error of which was reasonable and satisfactory. The results help judge the degree of pavement distress and provide data support for repair and maintenance, which has essential engineering significance.
UvA-DARE (Digital Academic Repository) EZH2 Is Essential for Fate Determination in the Mammalian Isthmic Area

The polycomb group proteins (PcGs) are a group of epigenetic factors associated with gene silencing. They are found in several families of multiprotein complexes, including polycomb repressive complex 2 (PRC2). EZH2, EED and SUZ12 form the core components of the PRC2 complex, which is responsible for the mono, di-and trimethylation of lysine 27 of histone 3 (H3K27Me3), the chromatin mark associated with gene silencing. Loss-of-function studies of Ezh2 , the catalytic subunit of PRC2, have shown that PRC2 plays a role in regulating developmental transitions of neuronal progenitor cells (NPCs); from self-renewal to differentiation and the neurogenic-to-gliogenic fate switch. To further address the function of EZH2 and H3K27me3 during neuronal development, we generated a conditional mutant in which Ezh2 was removed in the mammalian isthmic (mid-hindbrain) region from E10.5 onward. Loss of Ezh2 changed the molecular coding of the anterior ventral hindbrain leading to a fate switch and the appearance of ectopic dopaminergic (DA) neurons. The correct speciﬁcation of the isthmic region is dependent on the signaling factors produced by the Isthmic organizer (IsO), located at the border of the mid-and hindbrain. We propose that the change of cellular fate is a result of the presence of Otx2 in the hindbrain of Ezh2 conditional knock-outs (cKOs) and a dysfunctional IsO, as represented by the loss of Fgf8 and Wnt1 . Our work implies that next to controlling developmental transitions, EZH2 mediated gene silencing is important for speciﬁcation of the isthmic region by inﬂuencing IsO functioning and repressing Otx2 in the hindbrain.
Early human motor

This review summarizes early human motor development. From early fetal age motor behavior is based on spontaneous neural activity: activity of networks in the brainstem and spinal cord that is modulated by su-praspinal activity. The supraspinal activity, ﬁ rst primarily brought about by the cortical subplate, later by the cortical plate, induces movement variation. Initially, movement variation especially serves exploration; its associated a ﬀ erent information is primarily used to sculpt the developing nervous system, and less to adapt motor behavior. In the next phase, beginning at function-speci ﬁ c ages, movement variation starts to serve adaptation. In sucking and swallowing, this phase emerges shortly before term age. In speech, gross and ﬁ ne motor development, it emerges from 3 to 4 months post-term onwards, i.e., when developmental focus in the primary sensory and motor cortices has shifted to the permanent cortical circuitries. With increasing age and increasing trial-and-error exploration, the infant improves its ability to use adaptive and e ﬃ cicient forms of upright gross motor behavior, manual activities and vocalizations belonging to the native language.
Dominance aﬀects determiner selection in language production q

Janssen and Caramazza (2003) show that when producing diminutives or plurals in Dutch, determiner information about the corresponding (singular) base form is active. This is reﬂected in a time cost for producing the plural or the diminutive with a gender-marked determiner when these forms and the corresponding singular or base form require diﬀerent determiners. No such cost is observed when singular and plural or base form and diminutive require the same determiner. In a series of picture naming experiments we show that this competition eﬀect is modulated by the relative dominance of the morphological forms. The results can be explained within an extension of the ‘‘primed unitised activation account’’ proposed by Alario and Caramazza (2002).
Mechanisms and Possible Strategies to Fight Against the Antibiotic Resistance

Antibiotic resistance (ABR) is a major concern for people nowadays. Apart from human-caused resistance, bacteria can develop self-resistance to antibiotics through a variety of mechanisms such as drug degradation, efflux, sequestration and target change. Due to resistance, the number of people infected with multidrug-resistant bacteria as well as the death toll is increasing every year which has led to enhanced economic cost. To ameliorate public health and keep our planet safe, it is high time to take proper action against the problem. Technological advancement could greatly assist in this aspect. Fragment-Based Drug Discovery (FBDD) and drug repurposing are such kinds of novel approaches that rely on advanced biophysical computational methods. While, FBDD uses a fragment library to identify potent molecules, drug repurposing mostly depends on the Food and Drug Administration (FDA) approved drugs. Another important strategy is iron chelation which is also an interesting way of fighting against ABR. This review emphasizes the importance of using advanced technology and novel approaches to address the problem in a more effective way. The combined effort of research for drug development and public health initiatives might be possible solutions to combat the growing antibiotic resistance threat.
Sensor and Actuator Fault Tolerant Control of Grid-Tied Microgrid

—The rising penetration of the deployed renewable energy resources (DERs) in the electrical grid introduces new challenges in terms of grid’s reliable operation. DERs are bonded to the backbone system at a Point of Common Coupling (PCC) at the distribution level, possibly via a micro grid. Micro grids generally operates in grid-tied and islanded modes. In islanded mode, the reactive and active power ought to reach balance with the load demand. , while in the grid-tied mode, the active and active powers must be desired criteria defined by the distribution system operator. Therefore, in both cases, proper control is vital to the microgrid’s operation and its DERs. In this article, a fault tolerant control (FTC) method bottomed on H ∞ observer is advised for a DER supplying a grid-tied microgrid to make it resilient against sensor and actuator faults and guarantee its reliable operation.
Improving Orchestration Service Using gRPC API and P4-Enabled SDN Switch in Cloud Computing Platform: An OpenStack Case

— Cloud computing platforms like OpenStack use orchestration as a crucial component in the deployment and administration of cloud services. For the deployment and management of virtualized resources, these platforms mainly rely on orchestration techniques. Cloud orchestration services like Service Function Chaining (SFC) have benefited from lower costs and increased scalability for cloud computing platforms thanks to the introduction of technologies like Software-Defined Networking (SDN) and Network Function Virtualization (NFV). The use of gRPC APIs and an SDN switch with P4 support is described in this research as an innovative method for enhancing SFC orchestration service in OpenStack computing platforms. The proposed approach uses a P4 enabled SDN switch and gRPC APIs to enhance network performance in data plane communication with the underlying infrastructure and performance in terms of service creation time between the SFC orchestration services. Our evaluation's findings demonstrate that this strategy greatly boosts the orchestration service's performance, making it more appropriate for usage in extensive cloud-based deployments. Additionally, the possibility of combining gRPC APIs and P4 switch to improve the efficiency and flexibility of orchestration service in cloud computing platforms is demonstrated by the performance analysis of the proposed approach on numerous platforms across diverse use cases.
When Tari⁄s Disrupt Global Supply Chains (cid:3)

We study unanticipated tari⁄s in a setting with (cid:133)rm-to-(cid:133)rm supply relationships. Firms conduct costly searches and negotiate with potential suppliers that pass a reservation level of match productivity. Global supply chains form in anticipation of free trade. Then, the home government surprises with an input tari⁄. This can lead to renegotiation with initial suppliers or search for replacements. Calibrating the model(cid:146)s parameters to match initial import shares and the estimated responses to the US tari⁄s imposed on China, we (cid:133)nd an overall welfare loss of 0.12% of GDP, with substantial contributions from changes in input sourcing and search costs
Inflation Targeting Policy Under Fixed and Floating Exchange Rate: Analysis Through the Simulation of a Semi-Structural Model for Morocco

: Morocco has shown its intention to adopt the inflation targeting policy. The latter requires the meeting of a set of preconditions for its implementation as the independence of the central bank, transparency and flexibility of the rate of change. In the literature, considerable importance has been given to the prerequisite of floating change for the success of this new monetary regime. The objective of this paper is to define the most advantageous exchange rate regime for Morocco as part of its vision to adopt the inflation targeting policy. Indeed, it focuses on the analysis of the responses of impulse functions to supply, demand, monetary policy and exchange rate shocks under fixed regime at first and under floating exchange rate regime at second. To do so, a semi-structural model called the "Quarterly Projection Macroeconomic Model" (QPM) of a small open economy will be applied to the case of Morocco, providing an adaptable framework and enabling a comprehensive examination of various potential scenarios. Consequently, the flexible framework of this model allows switching between the fixed and floating regime within in the context of the inflation targeting policy and facilitates the extraction of meaningful comparisons by evaluating the macroeconomic implications inherent to each of these scenarios. The main purpose is to determine which exchange rate regime would be best suited to the Moroccan context. The observation resulting from this analytical work argues that the readjustment of the economy takes place more quickly under the floating exchange rate regime. Also, the return of inflation to equilibrium occurs more quickly in the case of a floating exchange rate regime.
a 10-Year Series Segment Aneurysms: Retrospective Review of Cerebral Artery for the Treatment of P2 Endovascular Occlusion of the Posterior

BACKGROUND AND PURPOSE: P2 segment aneurysms develop between the junction of the posterior communicating artery with the posterior cerebral artery (PCA) and the posterior part of the midbrain in the ambient cistern. We reviewed our experience with parent artery occlusion in such aneurysms, looking for predictors of safety and effectiveness. METHODS: Clinical and preprocedural data from 10 patients, referred for endovascular treatment of P2 segment aneurysms, were retrospectively studied for prognostic factors influencing postoperative neurologic deficits caused by ischemia of the PCA distal territory. Patient tolerance was assessed by using clinical or anatomic criteria. Embryologic and anatomic features of the PCA were reviewed. RESULTS: Endovascular parent artery occlusion at the level of the aneurysmal neck was possible in nine cases. Control angiography after embolization showed that the aneurysm did not fill, and the distal PCA refilled via leptomeningeal anastomoses. One asymptomatic aneurysm could not be catheterized because of vascular tortuosity. No neurologic deficit occurred after treatment. Clinical presentations and grades were typical. No embryologic or anatomic configuration (eg, basilar tip arrangement, P2 position relative to the choroidal fissure, aneurysmal size or type [berry, fusiform, or serpentine]) was predictive of bad outcomes. CONCLUSION: Acute parent artery occlusion appears to be safe in the treatment of P2 segment aneurysms, whatever the location of the occlusion. In our series, potential collateral supply and hemodynamic balance between the anterior and posterior choroidal arteries, pericallosal vessels, and anterior and middle cerebral vessels to the distal PCA made P2 occlusion safe, because the aneurysm occurred after the thalamoperforating vessels arose from the P1 segment. Aneurysms of the posterior cerebral artery (PCA) are
A characterization of class groups via sets of lengths

Let $H$ be a Krull monoid with class group $G$ such that every class contains a prime divisor. Then every nonunit $a \in H$ can be written as a finite product of irreducible elements. If $a=u\_1 \cdot \ldots \cdot u\_k$, with irreducibles $u\_1, \ldots u\_k \in H$, then $k$ is called the length of the factorization and the set $\mathsf L (a)$ of all possible $k$ is called the set of lengths of $a$. It is well-known that the system $\mathcal L (H) = \{\mathsf L (a) \mid a \in H \}$ depends only on the class group $G$. In the present paper we study the inverse question asking whether or not the system $\mathcal L (H)$ is characteristic for the class group. Consider a further Krull monoid $H'$ with class group $G'$ such that every class contains a prime divisor and suppose that $\mathcal L (H) = \mathcal L (H')$. We show that, if one of the groups $G$ and $G'$ is finite and has rank at most two, then $G$ and $G'$ are isomorphic (apart from two well-known pairings).
The changes of the natural resources access in the small forestry Mediterranean islands: The case study of Skiathos, Greece

It is known that island forests constitute rare and, at the same time, vulnerable ecosystems that express the complexity and the ecologic interactions of our planet. Ecosystems of island regions change at great speed and, in most cases, they are environmentally degraded. The right management of the natural assets of island forest regions and, at the same time, the socio-economic growth of human resources constitutes the only solution for the achievement of sustainable development. Sustainable management of forest resources can only be achieved through a well-organized road network based on spatial planning. The aim of this paper is to present the progress of the existing forest road network at the Island of Skiathos for the last decades. With the contribution of Geographic Information Systems (GIS) and orthophotomaps, spatial planning of the forest road network can be evaluated for all these years and Road Density can also be calculated. Thematic maps of the forest roads, for each year separately, will also be presented. The current study explores the application of spatial planning in forest roads in order to achieve sustainable development with respect to nature assets and the landscape, in combination with viable forest exploitation.
Tectonic outline and structural styles of the Tongbai collisional orogen and its neighbors

The Tongbai collisional orogen and its neighbors can be divided into nine tectonic units.They are,from north to south, the southern margin of the North China Craton tectonic unit-the Kuanping Group,the Erlangping tectonic unit with the nature of backarc basin,the Qinling complex unit with the nature of island arc,the Guishan Group and the Nanwan Group composed of leading-edge wedge of the subduction zone,the tectonic melange zone,the northern high-pressure(HP) unit,the Tongbaishan high-grade complex, the southern HP unit,the Suizhou tectonic deformation zone.According to structural analysis and new geochronological evidences,five distinct episodes of deformation(D_1-D_5) are distinguished in this area since the Mesozoic.The former two-episode of deformation developed in the various tectonic units south of tectonic melange zone,and the latter three-episode of deformation developed in all units of this area The time of the D_1 episode is about 255～238Ma. D_1 formed regional penetrative foliations and the WNW-oriented stretching lineations,and led to the early stage of extrusion of the high-pressure rocks from west to east D_2 maybe occurred at some time about 230～215Ma,characterized with the southward-directed thrust which made the high-pressure rocks further vertical uplift. D_3 should be earlier than Lower Jurassic,and nearly WNW trending open folds as the main characteristics of this episode,during which the Tongbaishan high-grade complex and the high-pressure rock units were synchronously uplift. D_4 occurred in roughly between 140～130Ma,characterized with the activities of the ductile shear zones,and during this episode the Tongbaishan high-grade complex was extruded to the east. D_5 occurred in 120～80Ma,characterized with the activities of NW and NE trending brittle faults which cut all of the above structural features.The exhumation of Tongbaishan high-pressure rocks are controlled by many episodes of deformation, displaying generally staged uplift and exhumation.
The Social Organization of the Provisioned Japanese Monkey Troops Which Have Extraordinary Large Population Sizes

Two Provisioned Japanese monkey troops, the Takasakiyama A and B troops have extraordinary large population sizes, consisting of about 1000 and 300 monkeys respectively. Dominance tests were conducted among identified adult females of the Takasakiyama A and B troops. Becausemany pairs showed indefinite dominance relationships and the linear dominancerank order was not observed, individuals were given "dominance rank by ratio ". Information of the dominance tests was obtained about two other troops. Indefiniteness of the cominance relationships increased quantitatively and qualitatively with the increase of the population size of the troop. The discrepancy up to now in the reports about the process of troop divisionsis related to the population size of the troops and the occurence of indefinite dominance pairs.

How Bedrock‐Controlled Channel Migration Can Structure Selective Preservation of Archaeological Sites: Implications for Modeling Paleoindian Settlement

Although Paleoindian sites in Indiana, USA, are commonly located on late Wisconsin (Last Glacial Maximum) outwash terraces, drainage basin development since deglaciation often obscures the visibility of such sites on flood plains by either burying them under alluvium or destroying them through erosion. Significant clusters of Paleoindian and Early Archaic sites, however, have been identified proximal to the modern White River channel in central Indiana on what is mapped as “floodplain. ” These site cluster locations are patterned. They typically occur within bedrock‐controlled river reaches but are rare along unconfined meandering reaches. Subsurface reconnaissance and chronology indicate that despite the fact that they often flood, portions of the so‐called flood plains within bedrock‐confined reaches are actually terraces constructed of late Wisconsin outwash with minimal overbank sedimentation. Terrace preservation in these settings is a result of bedrock structure that protects older sediments from lateral erosion and differentially preserves archaeological sites near the modern channel in bedrock‐controlled reaches. Comparisons of archaeological sites within bedrock‐controlled segments of the White River to those in unconfined meandering segments suggests that significant numbers of Paleoindian and Early Archaic sites may be missing from river settings across the midcontinent. These findings demonstrate that bedrock channel controls are important to recognize when assessing prehistoric settlement distributions.
An Abnormal Behavior Detection Method Leveraging Multi-modal Data Fusion and Deep Mining

—At present, the increasingly prominent mental health problems of college students have gradually become the focus of the society, universities and families. According to the current situation and challenges of mental health work of college students, we put forward the idea of constructing an early warning platform for college students’ psychological crisis based on deep neural networks. The purpose of constructing this platform is to comprehensively improve the psychological health of college students and to purposefully prevent and intervene the psychological crisis. In this paper, we focus on describing the structure, composition of proposed platform and functions of each module, and then give a specific framework, training and testing scheme for the core part of the platform, which is the neural network model for real-time monitoring and analysis of students’ mental health. Finally, we demonstrate the effectiveness of the deep neural network for analyzing behavior patterns through simulation experiments on the generated data set.
