Maritime Tel Michal and Apollonia: Results of the underwater survey 1989-1996

The results of this work are based on investigations conducted over a period of four years at Tel Michal and Apollonia, and are the result of 2,300 actual underwater hours. Evidence collected from written sources and field-work brings the authors to the conclusion that the Mediterranean coastal harbour, or anchorage, at Tel Michal (on the Israeli Sharon Plain) was located in an estuary on the southern or south-eastern side of the high tell. Excavations show habitation from the Middle Bronze Age to the Persian period. Tel Michal declined during Persian rule as Apollonia (lying 3.5 km north) was founded and grew in importance. The overall objectives of the study were to determine whether the two settlements possessed their own harbours, anchorages or beaching shores, or whether their economic development was solely dependent on the hinterland and land-borne transport.
Using Microalga Scenedesmus quadricauda for the Improvement of Municipal Wastewater Quality

Microalgae culture is an interesting step in wastewater treatment since it provides a tertiary biotreatment while also producing potentially valuable biomass that may be used for a variety of applications. Microalgae cultures, with their ability to utilize inorganic nitrogen and phosphate for growth, provide an elegant solution to tertiary and quaternary treatments. Scenedesmus quadricauda culture was employed with three different doses, 2g/l, 1g/l, and 0.2g/l, to investigate the impacts of microalgae in wastewater. Standard procedures were used to measure samples for physicochemical parameters such as pH, EC, PO 4 , NO 3 , NO 2 , NH 4 and BOD 5 every third day for 21 days. Results showed that a higher dose of 2g.l -1 was the most effective for removing the highest rate of nutrients. It was confirmed by significant differences (p≤0.05) between all doses. Ammonium pass had the highest removal percentage of 97%, followed by NO 3 with 95.7%, and BOD 5 with a range of 90.3 to 93.5 %. Decreases in nutrients were accompanied by a rise in chlorophyll content, with the greatest biomass of 1.52 mg. l -1 on the 17 th day of the experiment. The purpose of this paper is to provide an overview of the methods that microalgae use to bioremediate organic contaminants in aquatic ecosystems.
S IMULATION OF REACTING AND MOVING GRANULAR ASSEMBLIES OF THERMALLY THICK PARTICLES BY DEM /CFD A B RIEF OVERVIEW

This paper briefly summarizes the potential and the limitations of the Discrete Element Method (DEM) coupled with Computational Fluid Mechanics (CFD) to simulate chemically reacting, moving granular material passed by fluid flow. A special focus is set on thermally thick particles, which requires to resolve the intra-particle transport and reaction processes. The aspect of complex particle shape is addressed as shape may dominate the particle movement in densely packed granular assemblies even more than details of contact force laws. The fluid flow in the granular assembly is assumed to be a gas, i.e. solid-liquid systems are not considered. The potential of DEM/CFD will be highlighted presenting three illustrative examples: a large-scale lime shaft kiln with intermittent operation, an industrial-size grate firing system for the incineration of municipal waste, and a small-scale straw pellet stove. In the summary, an outlook is given on open questions and further research needs.
L OCAL F LOW R ESOLUTION WITH THE B LOCKED -O FF M ETHOD IN DEM-CFD: G ASEOUS F UEL J ET D ISPERSION AND C OMBUSTION IN A P ARTICLE A SSEMBLY

DEM-CFD simulation of reacting flows inside large-scale granular assemblies remains a challenging task. Resolving the flow field within the voids is required to obtain correct conversion rates but due to the computational resources required, this high resolution cannot be employed on the device-scale. In the current work, a combined approach is employed: the so-called blocked-off method is used to resolve the voids between particles within a prescribed refinement region, while the volume-averaged method is applied to the rest of the domain because of its low computational effort. This approach is firstly tested in a case where nitrogen is injected into an air cross-flow. A good agreement with oxygen concentration measurements is obtained when applying the blocked-off method to the whole domain and locally, whereas the volume-averaged method under-predicts the local oxygen concentration since jet dispersion is too low. The latter is also observed in a second case where methane is injected in cross-flow into an air stream with subsequent reaction of the methane. As a result, the locally resolved approach predicts significantly larger reaction rates associated with higher maximum temperatures as well a larger spread of the area with high temperatures than the volume-averaged method.
Linear Phase Paraunitary Filter Bank with Filters of Different Lengths and Its Application in Image Compression Sp Edics: Sp 2.4.2

In this paper, the theory, structure, design, and implementation of a new class of linear phase paraunitary lter banks (LPPUFB) are investigated. This new class of lter banks with lters of diierent lengths can be viewed as generalized lapped orthogonal transforms (GenLOT) with variable-length basis functions. Our main motivation of the new transform is its application in block-transform-based image coding. Besides having all of the attractive properties of other lapped orthogonal transforms, the new transform takes advantage of its long basis functions to represent smooth signal and to reduce blocking artifacts, while reserves its short basis functions for high-frequency signal components like edges and texture to reduce ringing. Two design methods are presented, each with its own set of advantages: the rst is based on a direct lattice factorization and the second enforces certain relationships between GenLOT's lattice coeecients to obtain variable length lters. Various necessary conditions for the existence of meaningful solutions are derived and discussed in both cases. Finally, several design and image coding examples are presented to connrm the validity of the theory.
A Mid-Continent Irruption of Canada Lynx, 1962-63

: There was a mid-continent irruption of the Canada lynx (Felis lynx) population and sub sequent extensive movement into non-lynx habitats during the years 1962-1963. Lynx were found in the prairie provinces of Canada and the prairie areas of Minnesota, and North and South Dakota. They were also found in urban areas such as Minneapolis and St. Paul, Minnesota: Winnipeg, Manitoba: and Calgary, Saskatchewan, Canada. Causes for the irruption remain unknown but speculations include primarily a change in snowshoe hare population, disease, extensive forest fires and extensive spraying. Unusual behavior seemed to be most often reflected by a lack of fear.
Inter-annual comparison of measured turbulent fluxes over snow at a wind-sheltered and a wind-exposed site using eddy covariance

Measurements of sensible and latent heat fluxes using eddy covariance (EC) instrumentation over snow in complex terrain have become more common in the past decade. Analysis ot EC measurements at two sites, wind-exposed and wind-protected, for three consecutive years is presented. The analysis focused on how site conditions influence inter-annual variability of EC-measured turbulent fluxes. The protected site yields essentially the same turbulent fluxes, regardless of meteorological inter-annual variability. The exposed site yields turbulent fluxes that are several times the magnitude of the fluxes measured at the protected site. Sublimation for the season is relatively constant for the years studied, and hence constitute a larger percentage of the snow pack during below average water years. Sensible heat dominates the turbulent flux early in the season while latent heat dominates turbulent fluxes later in the season.
Realizing High Efficiency and High Color Quality for All‐Fluorescence White Organic Light‐Emitting Diodes by Interlayer‐Sensitizing Configuration with Electron‐Capturing Agent

As a promising next‐generation lighting technology, all‐fluorescence white organic light‐emitting diodes (WOLEDs) have advanced rapidly but still face the formidable challenge of achieving high efficiencies and high color quality simultaneously. Herein, an interlayer sensitization strategy assisted by electron‐capturing agent with thermally activated delayed fluorescence (TADF) is proposed for the fabrication of high‐performance all‐fluorescence WOLEDs. The proof‐of‐concept three‐color devices with an interlayer‐sensitizing configuration are designed, and a low concentration of TADF electron‐capturing agent is codoped with a red conventional fluorescence (CF) emitter to reduce exciton loss. The major energy transfer from TADF sensitizing layer to red CF emitter combined with the supplementary energy transfer from TADF electron‐capturing agent to CF emitter can successfully increase exciton utilization. The synergistic effect endows the three‐color all‐fluorescence WOLEDs with high efficiencies, high color quality, and improved efficiency stability and operational stability, simultaneously. The resultant WOLEDs successfully attain remarkable external quantum efficiency of 31.0%, outstanding color rendering index of 93 and long operational lifetime. The record‐beating comprehensive performances of these WOLEDs strongly demonstrate the great potential of the proposed strategy for the exploration of high‐performance all‐fluorescence WOLEDs.

The presence of control-flow divergence in loops can either hinder or impede auto-vectorization as a compiler transformation to exploit parallelism enabled by Single-Instruction Multiple-Data (SIMD) instructions. A solution is to linearize control flow through the use of predicated execution. However, computation resources are wasted when predicated instructions are executed but not committed because of a false predicate. Alternative approaches optimistically avoid predicated instructions when all conditions in a vectorized loop iteration evaluate to the same value. However, dynamic uniformity is less frequent in long vectors. Active-Lane-Consolidation (ALC) was proposed to form uniform vectors dynamically by merging active elements from different iterations. In its seminal presentation, ALC was only evaluated in a simulated environment through hand-modified programs. This thesis presents the first performance evaluation of ALC on real hardware which reveals that the original design of ALC indeed reduces the number of executed instructions, but it fails to provide speedup over auto-vectorized code. It then presents a change to the design of ALC that results in it outperforming auto-vectorized code and describes the first compiler-enabled transformation that applies ALC as a compiler optimization pass. The experimental results show that compiler-generated ALC code outperforms auto-vectorized code, produced by state-of-the-art compilers, by
Processus physiques et chimiques en failles sismiques : exemples de failles actives et exhumées

Les processus physiques et chimiques actives pendant le cycle sismique determinent l'evolution des proprietes mecaniques des failles, a court terme (pendant un seisme) comme a long terme (la recuperation des propretes elastiques des roches de faille apres un seisme). L'etude des roches de faille naturelles est un moyen pour identifier les processus actives pendant les diverses phases des cycle seismique. En cette these, echantillons prevenants de deux failles seismiques sont etudies: la Faille de San Andreas (California, USA), une faille seismique active, et la faille de Gole Larghe (Alpes Meridionales, Italie), une faille seismique exhumee. La Faille de San Andreas a ete foree jusqu'a 2.7km de profondeur. Les echantillons montrent une superposition de: pression-dissolution - hydrofracturation - pression dissolution. La succession des events est compatible avec la formation de sacs de fluides dans zones de basse permeabilite dans la faille, ou la pression de fluides augmente a cause de le progressif compactage de le gouge de faille, jusqu'a la nucleation de une rupture. La faille de Gole Larghe est une faille exhumee, qui a preserve des pseudotachylytes (roches fondues par le chaleur de friction pendant une frottement seismique) formees a 9 - 11 km de profondeur il y a 30 millions d'annees. Deux argumentes sont traites: (i) l'evolution des microstructures des cataclasites associees a les pseudotachylytes, pour identifier les processus qui peuvent porter a la formation de instabilites frictionnelles pendant les premieres phases de croissance de une faille. (ii) L'origine des fluides en failles seismiques et pendant la fusion pour friction. La formation de un systeme de failles a cataclasites permit la percolation de un fluide aqueux de profondeur. La composition isotopique des pseudotachylytes (calcule sans la component de hydratation) est proche a celle des pseudotachylytes reproduites en experiences du laboratoire (sans fluides). La principale source de fluides pendant la fusion pour friction est donc la deshydratation des mineraux hydrate des roches autour de la faille.
Rejected and Excluded Forevermore, but Even More Devoted

When people are ostrasized (i.e., rejected and excluded) by either an outgroup or an ingroup, they may either withdraw or engage in compensatory activities designed to reaffirm their social identity as a group member. The authors proposed here that individual differences in identity fusion (an index of familial orientation toward the group) would moderate the tendency for people to display such compensatory activity. Consistent with this reasoning, the results of four experiments showed that irrevocable ostracism increased endorsement of extreme, pro-group actions (fighting and dying for the ingroup) among fused persons but not among nonfused persons. This effect emerged when an outgroup ostracized fused individuals due either to their nationality (Experiment 1) or their personal preferences (Experiment 2). Similarly, ostracism by the ingroup amplified the tendency for fused persons to both endorse extreme pro-group actions, refuse to leave the group (Experiment 3), and donate money to an ingroup member (Experiment 4). Finally, compensatory activities emerged even when ostracism was based on being “too good” for the group, suggesting that a desire for self-enhancement does not mediate such activities (Experiment 4).

1 Lymphoid organs exhibit complex structures tightly related to their function. Surprisingly, although the thymic medulla constitutes a specialized microenvironment dedicated to the induction of T cell tolerance, its three-dimensional topology remains largely elusive because it has been studied mainly in two dimensions using thymic sections. To overcome this limitation, we have developed an automated method for full organ reconstruction in three dimensions, allowing visualization of intact mouse lymphoid organs from a collection of immunolabeled slices. We validated full organ reconstruction in three dimensions by reconstructing the well-characterized structure of skin-draining lymph nodes, before revisiting the complex and poorly described corticomedullary organization of the thymus. Wild-type thymi contain ∼200 small medullae that are connected to or separated from a major medullary compartment. In contrast, thymi of immunodeficient Rag2 2/2 mice exhibit only ∼20 small, unconnected medullary islets. Upon total body irradiation, medullary complexity was partially reduced and then recovered upon bone marrow transplantation. This intricate topology presents fractal properties, resulting in a considerable corticomedullary area. This feature ensures short distances between cortex and medulla, hence efficient thymocyte migration, as assessed by mathematical models. Remarkably, this junction is enriched, particularly in neonates, in medullary thymic epithelial cells expressing the autoimmune regulator. The emergence of a major medullary compartment is induced by CD4 + thymocytes via CD80/86 and lymphotoxin-a signals. This comprehensive three-dimensional view of the medulla emphasizes a complex topology favoring efficient interactions between developing T cells and autoimmune regulator–positive medullary thymic epithelial cells, a key process for central tolerance induction. T lymphocytes play critical roles in cell-mediated immunity and are generated in the thymus by sequential maturation and selection events. The thymus is divided into a cortex, supporting the earliest events in thymocyte development , and a medulla, in which thymocytes undergo final selection processes (1, 2). The thymus is composed of a highly organized three-dimensional (3D) network of cortical and med-ullary thymic epithelial cells (cTECs and mTECs, respectively) (3). The cTECs promote positive selection, leading to survival of double-positive (DP) CD4 + CD8 + thymocytes carrying TCRs capable of interacting with self-MHC (4). Positively selected thymocytes become CD8 + or CD4 + single-positive (SP), depending on their interactions with MHC class I or II expressed by cTECs. They then migrate into the medulla in a CCR7-dependent manner (5). The medulla promotes negative selection , which consists in eliminating autoreactive SP thymocytes that carry TCRs exhibiting high affinities for self-antigen–MHC …
Quasi‐elliptical band‐pass filters based on compact spiral resonators for C‐band applications

This letter proposes a quasi‐elliptical passband filter in via‐less microstrip technology. The filter is based on the Archimedean spiral, enabling a compact and low‐loss response with sharp transitions to stop bands. The developed filters fabricated on a commercial substrate, present losses below 2 dB within a 3 dB bandwidth of 500 MHz, and isolation exceeding 20 dB. Its extremely compact dimension, about 0.018 λ02 , and the low‐cost of fabrication, permits the integration within compact front‐end PCB.
Study on temperature field and deformation field of AMT dry clutch assembly under continuous slip grinding

In this paper, Ansys finite element analysis was used to study the temperature and deformation fields of clutches after continuous slip grinding for the 30s, 45s, and 60s, under different constraints on the pressure plate, and after cooling to room temperature. Its sliding time is extended while cooling the clutch from the highest temperature to the initial temperature through a certain setting, and then its temperature field and deformation field are analyzed at different sliding times after cooling. Through this study, we can explore the performance of this clutch under extremely harsh working conditions, to analyze whether it meets the standard of use of the corresponding car or makes corresponding optimization improvements. As the sliding time increases, the maximum temperature of the clutch rises, and the temperature is transmitted to the inner and outer diameters centered on the sliding surface. As the temperature generated by continuous sliding grinding continues to rise, the deformation of the clutch assembly also increases, and when the temperature drops, the clutch will quickly reduce a certain amount of deformation in a short period and then gradually return to its original shape. The higher the temperature, the more likely the clutch is to deform. When the temperature is at a lower value, its ability to deform and its rebound performance will also decrease.
Experimental study of a pump in turbine mode, energy characteristics, selection methods and operation in a system

This paper reveals the issues related to the operation of a standard centrifugal pump in turbine mode. The features related to predicting the parameters of the pump, when operating both as a turbine and operating in a system, are considered. An experimental study of a centrifugal pump with a specific frequency NSp=34 is made. The characteristics of the machine in pump and turbine mode are determined. A comparison is made with related models for pump selection for operation in turbine mode. The deviations in the obtained results were evaluated theoretically and experimentally. The obtained results are compared with models for predicting machine parameters in turbine mode, and there are considered different cases of operation of the particular machine in a system.
Tensile and Fracture Properties of the Ag/W Composite Interface from First-Principle Calculation

As an important electrical contact composite, the interface bonding properties of Ag/W composite directly affect its functional properties and subsequent processing properties. In this paper, the mechanical properties and the adhesion strength of Ag(111)/W(100), Ag (111)/W(110), and Ag(111)/W(111) models are investigated by means of first-principles calculations. The Stress-strain curve reveals that the Ag/W composite interface structures have good tensile mechanical properties. The charge density shows that charge transfer occurs near the interface, which is the main reason that affects the fracture performance, and it occurs mainly between the first and second layers on the Ag side. The results of adhesion work and interface energy cannot be used to indicate the interfacial tensile strength.
Circulation of SARS-CoV-2 and co-infection with Plasmodium falciparum in Equatorial Guinea

The impact of COVID-19 in Africa has been a big concern since the beginning of the pandemic. However, low incidence of COVID-19 case severity and mortality has been reported in many African countries, although data are highly heterogeneous and, in some regions, like Sub-Saharan Africa, very scarce. Many of these regions are also the cradle of endemic infectious diseases like malaria. The aim of this study was to determine the prevalence of SARS-CoV-2, the diversity and origin of circulating variants as well as the frequency of co-infections with malaria in Equatorial Guinea. For this purpose, we conducted antigen diagnostic tests for SARS-CoV-2, and microscopy examinations for malaria of 1,556 volunteers at six health centres in Bioko and Bata from June to October 2021. Nasopharyngeal swab samples were also taken for molecular detection of SARS-CoV-2 by RT-qPCR and whole genome viral sequencing. We report 3.0% of SARS-CoV-2 and 24.4% of malaria prevalence over the sampling in Equatorial Guinea. SARS-CoV-2 cases were found at a similar frequency in all age groups, whereas the age groups most frequently affected by malaria were children (36.8% [95% CI 30.9-42.7]) and teenagers (34.7% [95% CI 29.5-39.9]). We found six cases of confirmed co-infection of malaria and SARS-CoV-2 distributed among all age groups, representing a 0.4% frequency of co-infection in the whole sampled population. Interestingly, the majority of malaria and SARS-CoV-2 co-infections were mild. We obtained the genome sequences of 43 SARS-CoV-2 isolates, most of which belong to the lineage Delta (AY.43) and that according to our pandemic-scale phylogenies were introduced from Europe in multiple occasions (7 transmission groups and 17 unique introductions). This study is relevant in providing first-time estimates of the actual prevalence of SARS-CoV-2 in this malaria-endemic country, with the identification of circulating variants, their origin, and the occurrence of SARS-CoV-2 and malaria co-infection.
