We report on the optical performance, structure and thermal stability of periodic multilayer films con- taining Zr and Al（lwt.-%Si） or Al（pure） layers designed for the use as extreme ultraviolet （EUV） high reflective mirrors in the range of 1~19 am. The comparison of A1/Zr （Al（lwt.-%Si）/Zr and Al（pure）/Zr） multilayers fabricated by direct-current magnetron sputtering shows that the optical and structural per- formances of two systems have much difference because of Si doped in A1. From the results of grazing incidence X-ray reflection （GIXR）, X-ray diffraction （XRD）, and EUV, the Si can disfavor the crystalliza- tion of AI and smooth the interface, consequently increase the reflectance of EUV in the Al（lwt.-%Si）/Zr systems. For the thermal stability of two systems, the first significant structural changes appear at 250 ~C. The interlayers are transformed from symmetrical to asymmetrical, where the Zr-on-A1 interlayers are thicker than Al-on-Zr interlayers. At 295 ~C for Al（pure）/Zr and 298 ~C for Al（lwt.-%Si）/Zr, the interfaces consist of amorphous Al-Zr alloy transform to polycrystalline Al-Zr alloy which can decrease the surface roughness and smooth the interfaces. Above 300 ~C, the interdiffusion becomes larger, which can enlarge the differences between Zr-on-Al and Al-on-Zr interlayers. Based on the analyses, the Si doped in Al cannot only influence the optical and structural performances of Al/Zr systems, but also impact the reaction temperatures in the annealing process.

Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.

Introduction: The early detection of precancerous lesions being very important for the preventive management of cervical cancer, we felt it was important to identify these lesions on potential backgrounds including HIV-positive (HIV+) women to suggest control strategies of cervical cancer in Cameroon. Objective: To determine the prevalence of precancerous lesions in women infected with the human immunodeficiency virus (HIV), to investigate the determinants of the HIV and cervical cancer association, and to make recommendations regarding cervical cancer screening in these patients of the city of Douala. Methodology: Our study was a case-control cross-sectional study from July 2017 to December 2017 (6 months) including 108 women among which 34 HIV+ matched with 74 HIV-. HIV serology was done using the complete HIV enzygnost test. Cervical smears for cytological lesions were fixed to the cyto-fixator and then stained by the Papanicolaou technique and read under an optical microscope. The cervical smear slides for viral excretion were fixed with a methanol-acetone mixture of equal volume;HPV testing was done by the indirect immune-peroxidase technique using P16 protein. The excretion of HSV type 1 & 2 was investigated by the indirect immunofluorescence technique using the Simplex Virus type 1 & 2 Rabbit anti-Herpes from DAKO (France). Results: The two groups of women were compared with the chi square test with a significance threshold of P 0.05. The average age was 40.07 with extremes of 21 and 71 years and a standard deviation of 9.99. Of the 34 HIV+ patients, 23 had an abnormal cervix compared to 36 cases of abnormal cervix among HIV- with a statistically significant difference (P = 0.006649). 12 cases of dysplasia were observed in the 34 HIV+ women and distributed as follows: 0% of mild dysplasia, 18.92% of moderate dysplasia and 13.51% of severe dysplasia. In HIV- women we detected 6 cases of dysplasia including 1.35% of mild dysplasia, 4.05% of moderate dysplasia a

Introduction: Neglected ankle fractures are common in our regions. Patients first consult traditional healers and it is when the signs persist that they consult the surgeon for a swollen and painful ankle. Initially we always performed anatomical repairs with osteosynthesis, but the majority of patients still complained of pain and disability. We wondered whether a primary arthrodesis would not be indicated in old ankle fractures to avoid disabling pain for patients. We therefore performed a series of arthrodesis on neglected post-traumatic ankles. The objective of our study was to describe the results of arthrodesis on an old post-traumatic ankle and to propose a therapeutic indication in the face of any neglected ankle fracture. Material and Method: This was a prospective study over 8 years between December 2012 and November 2020, involving 36 cases of neglected ankle fractures treated by arthrodesis using Meary’s technique. We used AOFAS (American Orthopedic Foot and Ankle Score) preoperatively and postoperatively for an objective assessment. Results: The average follow-up was 4.2 years and our results were satisfactory (94.4%) with an average AOFAS score ranging from 27.8 preoperatively to 76.7 postoperatively. The fusion rate was 97.2%. Discussion: Arthrodesis appears here as an important alternative in the treatment of neglected ankle fractures with significant trophic disorders.

Lannea kerstingii is known for its multiple therapeutic and biological activities. Despite of many traditional uses of this plant, scientific research on the content of its chemical compounds is still limited. This study aims to isolate the chemical compounds contained in the n-butanol fraction of Lannea kerstingii leaves. The chemical investigation of the leaves of Lannea kerstingii led to isolation of three undescribed C-13 norisoprenoids, lankerstinol A-C (1-3), together with six (4-9) known flavonoid glycosides. The structures of these compounds were established by spectroscopic analyses.
