Jointly developed by Himax IGI, 3D AG, and polyscale innovations GmbH, this white paper outlines an end-to-end fabrication workflow designed to scale micro- and nanostructures from concept to industrial production. The workflow initiates with Himax IGI, leveraging large-area lithographic origination on glass substrates. This is followed by the tooling phase at 3D AG, where electroforming is used to produce high quality nickel shims. These shims are subsequently converted into cylindrical sleeves through specialized precision laser welding and forming techniques. The final stage is executed by polyscale innovations GmbH, focusing on industrial nanoimprint replication and rigorous quality control for structural fidelity and scalability. Analysis of the replicated microstructures demonstrates exceptional precision: <ul> • Angular accuracy: Deviations between microstructures are limited to ±0.32° </ul> <ul> • Planar dimensions: Accuracy is maintained within ±0.39 μm </ul> <ul> • Vertical fidelity: Reproducible structure height accuracy of ±0.12 μm </ul> This collaboration successfully integrates three specialized technical domains - origination, tooling, and volume replication into a synchronized industrial process. The results validate that clearly defined interfaces and unified quality standards enable a reliable transition from complex laboratory designs to high-volume, industrial-grade manufacturing.

Susu sapi merupakan komoditas ekonomi penting bagi masyarakat di wilayah Kecamatan Ngantang, Kabupaten Malang yang sebagian diantaranya berprofesi sebagai peternak sapi perah di bawah naugan Kelompok Usaha Bersama (KUB) peternak susu perah “Mustarika Jaya Makmur”. Sejak tahun 2017 produksi susu sapi menurun cukup signifikan selain dikarenakan berkurangnya jumlah peternak sapi dan jumlah sapi perah, juga karena kualitas susu sapi yang belum memenuhi Standar Nasional Indonesia (SNI) dari sisi nilai gizi. Di samping itu, lebih dari 42% peternak sapi perah saat ini adalah tidak lulus Sekolah Dasar (SD) dengan keterbatasan pengetahuan dalam pemeliharaan sapi perah sehingga belum mampu menghasilkan kualitas susu sapi yang sesuai dengan SNI. Kegiatan Pengabdian kepada Masyarakat ditujukan untuk memberikan peningkatan pengetahuan dan wawasan melalui pelatihan pembuatan complete feed (comfeed) guna meningkatkan gizi makanan sapi perah sehingga dapat menghasilkan kualitas susu sapi perah yang sesuai SNI. Pelatihan comfeed dilakukan pada 5 Oktober 2024 dan diikuti oleh 14 peternak sapi perah KUB “Mustarika Jaya Makmur” dan mitra terkait.

The Royal Treasury Museum (Lisbon) houses one of the richest collections of jewels in Europe and its collection of circa one thousand pieces, includes many that depict stylized plants. Studying them provides us with an insight into the symbolic use of plants in the societies that created them and reveals their links with the classical symbolic codes. A very precious jewel in the collection is the insignia of the Order of the Golden Fleece, made in the early years of the 19th century, with 1,741 diamonds (more than 300 carats), 190 rubies and one sapphire, arranged in the shape of palm leaves, laurel branches and oak fruits, whose symbolism alludes, not only the Portuguese Royalty, but to the Greco-Roman civilization and to the Christian doctrine.

The Azores Island of Corvo (Portugal) is home to a centuries-old woodworking tradition that has stood the test of time and passed down through generations. Central to this craft is cedro-do-mato [Juniperus brevifolia (Seub.) Antoine], an endemic species of juniper found in the Azores. Artisans on Corvo have honed their skills in working with this and other local woods to create a variety of functional wooden locks characterized by intricate carving techniques and a deep understanding of the material, which allows them to produce durable pieces. Cedro-do-mato is particularly significant, as this wood is prized for its durability, workability, and aromatic properties. This traditional craft reflects the resourcefulness of the island's inhabitants and plays a crucial role in preserving cultural heritage and maintaining a connection to the natural environment. The ongoing practice of this craft serves as a living testament to the sustainable use of local resources and the enduring cultural traditions of Corvo.

Introduction: Pregnancy and childbirth have an important role because of their enormous influence on human growth and development. Although there have been efforts to improve maternal health through various government programs, these efforts have only touched the physical aspect and have not yet made efforts to improve the psychosocial and psychiatric aspects of pregnant women. This is important because the growth and cognitive and emotional development of children are closely related to the mother's psychiatric problems during pregnancy. One of the efforts that can be done is an information program to educate individuals with emotional problems to be able to maintain homeostasis against unexpected changes or events that occur gradually, helping members cope with stress in life, focusing on dysfunctions of feelings, thoughts, and behaviors known as Therapeutic Group Therapy. Method: This research design uses quasi-experiments. The study subjects were taken by quota sampling, the sample of this study was pregnant women in the Kunciran Baru Health Center area of Tangerang City. The number of samples was 24 people. Data analysis using T-dependent test. Results: the statistical test obtained a P value of 0.024 (P value ≤ 0.05), so it can be concluded that there is a significant difference between the average delivery readiness of the intervention group and the control group. Conclusion: it was concluded that there was a significant difference between the average delivery readiness of the intervention group and the control group.

This study is done to evaluate the structural performances of bolted timber connections in local hardwoods. In Sarawak, Belian hardwood is typically used to construct the floor and wall diaphragm for unreinforced masonry (URM) buildings. Unfortunately, there is a lack of experimental data on bolted connection of Belian hardwoods. This gap in experimental data might lead to difficulties in designing bolted timber connections for strengthening purposes. Therefore, the study was carried out to evaluate the existing equations in predicting the bolted connection in Belian hardwood. A calibration factor for Belian hardwood will be provided to optimise the use of the current design equation in predicting the row shear failure mode. The European Yield Model (EYM) and Malaysia Standard (MS) will also be compared to the experimental results to verify the suitable equation to predict the strength of the ductile mode of failure. From the comparison between experimental versus prediction values, EYM and Row Shear equation were acceptable to predict the bearing and row shear failure while the MS was found too conservative with a range from 0.16 to 0.25 compared to the 5th percentile experimental results.

In this paper, we present the development of a miniaturized Laser Doppler Vibrometer (LDV) system, based on the 3D hybrid integration of the Si3N4 platform of LioniX (TriPleX) and the polymer platform of FhG-HHI (PolyBoard). The photonic integrated circuit (PIC) supports all the functionalities of an LDV system including the splitting of the input light to the measurement and the reference beam, the introduction of an optical frequency shift up to 100 kHz, polarization handling and detection of the reflected measurement beam, using a heterodyne detection technique. The optical frequency shift is accommodated in the TriPleX section of the PIC based on a simple serrodyne scheme, where a phase modulator is driven with a sawtooth signal with the desired frequency. The modulation of the optical field is based on the stress-optic effect utilizing thin-films of PZT deposited on top of the waveguide structures of the TriPleX platform, capable of supporting modulation frequencies up to several MHz. The PolyBoard part enables polarization handling and heterodyne detection of the reflected beam using micro-optic elements on chip, including a polarization beam splitter (PBS), a half wave plate (HWP), and a pair of balanced detectors with four photodiodes that are flip chip bonded on the top. The TriPleX and the PolyBoard platform were brought together based on the 3D hybrid integration, using mode size converters and vertical directional couplers with coupling losses lower than 15 dB. On-chip beating, using the integrated photodiodes is experimentally demonstrated.
