AbstractDuring MEMS device fabrication process, the residual stress of thin film caused by thermal expansion coefficient mismatch and lattice mismatch is an important factor that will deteriorate the properties of thin film and bring yield losses to MEMS devices. In this work, a method to release the residual stress by using a folded structure with V‐shaped grooves is proposed. The folded structures with different groove width and groove interval are fabricated and relative Raman frequency shift is adopted to calculate the residual stress. The minimum residual thermal stress of 11.6 MPa can be obtained in the folded structure models by simulation, which is about five times lower than the residual thermal stress of the flat structure. The minimum residual stress of 40 MPa can be obtained in the folded structure by experiment results, which is about 20 times lower than the residual stress of the flat structure. The simulation results and experimental analysis confirms that introducing a folded structure with groove into the design of MEMS device is an effective way to suppress the generation of residual stress, thus enhancing the reliability of MEMS devices.
Der Einfluss von subjektiven Krankheitstheorien auf Demoralisierung,

Längsschnittstudie
Authors: Bockholt Malin , Mehnert-Theuerkauf Anja , Vehling Sigrun 
Published: July 2021

Zusammenfassung
Hintergrund Diese Längsschnittstudie untersucht den Einfluss
der Ausprägung subjektiver Krankheitstheorien auf den zeitlichen
Verlauf von Demoralisierung, Depression und Angst bei Patienten mit einer
Krebserkrankung.
Methode Wir untersuchten n=307 Patienten mit gemischten
Tumordiagnosen und Erkrankungsstadien zu drei Messzeitpunkten:
während der ambulanten bzw. stationären Behandlung, nach 6
Monaten (n=213, 69%) sowie nach 12 Monaten (n=153,
50%). Subjektive Krankheitstheorien wurden anhand der Subskalen
Konsequenzen, Kontrolle, Behandlungskontrolle und Kohärenz des
Illness Perception Questionnaire (IPQ-R) erfasst. Psychische Belastung wurde
anhand der Demoralisierungsskala (DS) sowie der Module Depression und Angst
des Gesundheitsfragebogens für Patienten (PHQ-9 und GAD-7) erfasst.
Längsschnittliche Analysen erfolgten anhand von Varianzanalysen mit
Messwiederholung (MANOVA).
Ergebnisse Zu Studienbeginn nahmen 20% der Teilnehmer die
Erkrankung als mit einschneidenden Konsequenzen verbunden wahr
(12-Monats-Follow-up: 16%); 25% nahmen sie als
persönlich kontrollierbar (12-Monats-Follow-up: 17%),
42% als durch die medizinische Behandlung kontrollierbar
(12-Monats-Follow-up: 26%) und 24% als
kohärent/verstehbar wahr (12-Monats-Follow-up: 30%).
Zu Studienbeginn war die Wahrnehmung einschneidender Konsequenzen mit einer
signifikant höheren psychischen Belastung verbunden, von
Kontrollierbarkeit und Kohärenz mit einer signifikant geringeren
psychischen Belastung. Die Größe dieses Zusammenhangs war
jeweils am höchsten für Demoralisierung (Konsequenzen:
r=0,45, p<0,001, Kontrolle:
r=− 0,25, p<0,001, Behandlungskontrolle:
r=− 0,31, p<0,001, Kohärenz:
r=− 0,27, p<0,001). Keine der Subskalen
hatte einen signifikanten Einfluss auf die zeitliche Veränderung der
psychischen Belastung über den Verlauf von 12 Monaten
(d≤0,29, p≥0,09).
Diskussion Die subjektive Wahrnehmung einschneidender Konsequenzen,
geringer Kontrollierbarkeit sowie Verstehbarkeit der Erkrankung kann eine
wichtige Quelle für aktuell erlebte hohe Belastungen bei
Krebspatienten sein. Sie geht jedoch nicht zwangsläufig mit einem
weiteren Anstieg oder Abfall der psychischen Belastung einher. Ein
möglicher Grund könnte in den begrenzten
Möglichkeiten des eingesetzten IPQ-R liegen, adaptiv-angemessene von
maladaptiv-verzerrten Krankheitswahrnehmungen zu differenzieren.
Computed Tomography and Pathobiomechanical-Based Treatment of Volar Distal Radius Fractures
Authors: Hintringer Wolfgang , Rosenauer Rudolf , Quadlbauer Stefan 
Published: July 2021

AbstractToday, there are various classifications for distal radius fractures (DRF). However, they are primarily based on plain radiographs and do not provide sufficient information on the best treatment option. There are newer classifications that simultaneously consider the pathobiomechanical basis of the fracture mechanism and analysis of computed tomography images. Main determinants of which type of DRFs occurs are the strength/direction of the applied forces on the carpus and radius, and the position of the wrist relative to the radius during the fall. Reconstruction of the mechanism of injury provides information about which anatomic structures are involved, such as torn ligaments, bone fragments, and the dislocated osteoligamentous units. This article attempts to combine and modify current pathobiomechanically oriented classifications with an improved understanding of the “key fragments” to subsequently offer a treatment approach to stabilize these critical fragments through specific types of internal fixation.

Published: July 2021

Abstract
Background Data are limited concerning rates of perinatal complications in women with a body mass index (BMI) ≥40 kg/m2 compared to women with other BMI classes when guidelines for the safe prevention of the primary cesarean delivery are applied.
Objective The aim of the study is to evaluate labor guideline adherence by BMI class and to compare perinatal outcomes across BMI classes with guideline adherent management.
Study Design This retrospective study included low-risk women admitted for delivery between April 2014 and April 2017 after the labor guidelines were implemented. BMI closest to delivery was used for analysis. Women with cesarean for nonreassuring fetal status were excluded.
Results Guideline adherence decreased with increasing BMI, with 93% adherence among women of normal weight compared to 81% for class III obese women (p < 0.0001). Among women who had guideline-adherent management, there was increased rates of cesarean among class III versus other obesity classes; however, there were no differences in rates of infectious morbidity (p = 0.98) or hemorrhage (p = 0.93). Although newborns of women with class III obesity had higher rates of meconium at birth, neonatal outcomes were not different with increasing maternal BMI (p = 0.65).
Conclusion There were no differences in adverse perinatal outcomes with increasing BMI.
A unified energy-optimality criterion predicts human navigation paths and speeds
Authors: Brown Geoffrey L. , Seethapathi Nidhi , Srinivasan Manoj 
Published: July 2021

Significance
Why do humans move the way they do? Here, we obtain a physiologically based theory of the speeds and paths with which humans navigate their environment. We measure the metabolic energy cost of walking with turning and show that minimizing this cost explains diverse phenomena involving navigating around obstacles, walking in complex paths, and turning. We explain why humans slow down while turning, avoid sharp turns, do not always use the shortest path, and other naturalistic locomotor phenomena.

Published: July 2021

Significance
Cholesterol is present within the cell nucleus, where it associates with chromatin, but to date, a direct role for cholesterol in nuclear processes has not been identified. We demonstrate that the transcriptional repressor brain acid soluble protein 1 (BASP1) directly interacts with cholesterol within the cell nucleus through a consensus cholesterol interaction motif. BASP1 recruits cholesterol to the promoter region of target genes, where it is required to mediate chromatin remodeling and transcriptional repression. Our work demonstrates that cholesterol plays a direct role in transcriptional regulation.
Updated cosmological constraints on Macroscopic Dark Matter
Authors: Caloni Luca , Gerbino Martina , Lattanzi Massimiliano 
Published: July 2021

Abstract
We revise the cosmological phenomenology of Macroscopic Dark Matter (MDM) candidates, also commonly dubbed as Macros. A possible signature of MDM is the capture of baryons from the cosmological plasma in the pre-recombination epoch, with the consequent injection of high-energy photons in the baryon-photon plasma.
By keeping a phenomenological approach, we consider two broad classes of MDM in which Macros are composed either of ordinary matter or antimatter. In both scenarios, we also analyze the impact of a non-vanishing electric charge carried by Macros.
We derive constraints on the Macro parameter space from three cosmological processes: the change in the baryon density between the end of the Big Bang Nucleosynthesis (BBN) and the Cosmic Microwave Background (CMB) decoupling, the production of spectral distortions in the CMB and the kinetic coupling between charged MDM and baryons at the time of recombination.
In the case of neutral Macros we find that the tightest constraints are set by the baryon density condition in most of the parameter space. For Macros composed of ordinary matter and with binding energy I, this leads to the following bound on the reduced cross-section: σX/M
X ≲ 6.8 · 10-7(I/MeV)-1.56 cm2 g-1. Charged Macros with surface potential V
X, instead, are mainly constrained by the tight coupling with baryons, resulting in σX/MX ≲ 2 · 10-11(|V
X|/MeV)-2cm2 g-1.
Finally, we show that future CMB spectral distortions experiments, like PIXIE and SuperPIXIE, would have the sensitivity to probe larger regions of the parameter space: this would allow either for a possible evidence or for an improvement of the current bounds on Macros as dark matter candidates.
Flavors of astrophysical neutrinos with active-sterile mixing
Authors: Ahlers Markus , Bustamante Mauricio , Nortvig Willesen Niels Gustav 
Published: July 2021

Abstract
We revisit the flavor composition of high-energy astrophysical neutrinos observed at neutrino telescopes. Assuming unitary time evolution of the neutrino flavor states, the flavor composition observable at Earth is related to the initial composition at their sources via oscillation-averaged flavor transitions. In a previous study we derived general bounds on the flavor composition of TeV–PeV astrophysical neutrinos assuming three-flavor unitary mixing. We extend these bounds to the case of active-sterile neutrino mixing. Our bounds are analytical, derived based only on the unitarity of the mixing, and do not require sampling over the values of the unknown active-sterile mixing parameters. These bounds apply to any extended active-sterile neutrino mixing scenario where energy-dependent nonstandard flavor mixing dominates over the standard mixing observed in accelerator, reactor, and atmospheric neutrino oscillations.
Prospects for measuring dark matter microphysics with observations of dwarf spheroidal galaxies
Authors: Baxter Eric J. , Kumar Jason , Pace Andrew B. , Runburg Jack 
Published: July 2021

Abstract
Dark matter annihilation in dwarf spheroidal (dSph) galaxies near the Milky Way has the potential to produce a detectable signature in gamma-rays. The amplitude of this signal depends on the dark matter density in a dSph, the dark matter particle mass, the number of photons produced in an annihilation, and the possibly velocity-dependent dark matter annihilation cross section. We argue that if the amplitude of the annihilation signal from multiple dSphs can be measured, it is possible to determine the velocity-dependence of the annihilation cross section. However, we show that doing so will require improved constraints on the dSph density profiles, including control of possible sources of systematic uncertainty. Making reasonable assumptions about future improvements, we make forecasts for the ability of current and future experiments — including Fermi, CTA and AMEGO — to constrain the dark matter annihilation velocity dependence.

Abstract
This pandemic also affected the amount of costs incurred from the teak harvesting process. Based on previous research, we tried to compare the costs arising from teak harvesting during the pandemic. On the other hand, Cost analysis of community teak harvesting aims to analyse the costs incurred by the community at each harvesting process, starting at the felling, skidding, to transportation stages, both in self-managed systems and in wholesale systems. Data were collected through observation and interviews which were then analysed using quantitative descriptive analysis by calculating the costs for each harvesting process. Machine costs are obtained by adding up fixed costs and variable costs incurred, while operating costs are obtained by adding up machine costs with operator and helper wages. The results showed that the total cost for felling group I was IDR 53,837.17 per m3 with an average cutting ability of 0.72 m3 per hour. Meanwhile, the total cost for felling group II was IDR 40,361.69 per m3 with an average cutting capacity of 0.87 m3 per hour. Loggers’ costs of harvesting forests during the pandemic do not differ significantly from the costs incurred by loggers before the COVID-19 pandemic.

Abstract
The measurement of company performance usually uses the analysis of Return on Investment (Rol), Return in Earning (RoE), Business Rentability (Ru) and Economic Rentability (Re) to assess the level of profit against capital, which means the extent to which business activities have a positive impact on capital owners, but it has not yet described the impact on human resources. The solution offered is the measurement of the company’s performance using Value Added Rentabilty (Rnt), so that the impact on the welfare of business actors can be known. Data was collected from all tofu agro-industry business units in North Lombok Regency. Data collection is done by using a survey method based on a list of questions. The survey was conducted 2 (two) times before and after the earthquake, namely in June 2018 and June 2019 for 24 respondents of business owners. The results showed that Value Added Rentabilty (Rnt) before earthquake in 2018 was 216.82% and post-earthquake in 2019 was 316.81%, meaning that the income obtained by capital owners from profits and labor wages was greater after the earthquake than before the earthquake for one IDR use of capital.

Published: July 2021

Abstract
Fruit bats have important roles in the ecosystem serving not only as pollinator agents for various high economic values plants but also acting as seed disperser for many plants in the forests. Ecosystem services provided by the bats are still overlooked while the animals also experienced intensive hunting. Lack of knowledge on the importance of the fruit bats in the ecological chain combined with poor public perception of the animals have contributed to the decline of the bats. This research is aimed to examine knowledge, experiences, perceptions, and awareness of community on fruit bats and analyze the relationship of the four aspects towards the conservation behavior of community towards fruit bats in three different regencies of South Sulawesi (Maros, Sinjai and Soppeng). In-depth interviews using questionnaires to community living nearby the roosting habitats of fruit bats were carried out to collect data on knowledge, experience, perception, awareness and conservation behavior. Correlation analysis of Spearman rank was employed to determine the relationships between variables measured with the conservation behavior of community towards fruit bats. The results showed that on total of 90 respondents interviewed in the three regencies, there were differences on the level of knowledge, experience, perception, awareness, and behavior. It was found that Maros had the highest percentage related with conservation behaviour (78%) followed by Soppeng (76%) while Sinjai had the lowest (64%). Meanwhile, the analysis between all variables towards the conservation behavior had also shown that there were differences between variables tested on conservation behavior occurred in the three regencies. In Maros, better knowledge had positive influenced towards conservation behavior while in Sinjai low level of awareness had driven the behavior. In contrary, for Soppeng none of variables can be found influencing the variables tested and this can be due to the existence of local regulation and cultural norms which were enacted by the local government of Soppeng Regency on fruit bat’s protection.

Abstract
Corn flour can be used as a raw material for making bread as a substitute for wheat flour. Although it does not have sufficient gluten to develop bread, it has added value to bread by using modified cornflour. This study aims to determine the best formulation for processing modified cornflour into bread based on SNI and organoleptic. This research was conducted with a completely randomized design (CRD) with 3 replications. The treatment in this study was the substitution of wheat flour using modified cornflour with a concentration of 0% (control), 20%, 40%, and 60%. The results showed that the highest water and carbohydrate content was obtained from substitution with 20% modified cornflour, highest ash and fat content from 40% modified cornflour substitution, and the highest protein content was found in the control treatment or without modified cornflour substitution. Organoleptic testing showed no significant differences (p>0.05) in color and aroma of all treatments, while for texture, taste, and overall appearance, the highest score was obtained from control and substitution with 20% modified cornflour, where the score obtained for 20% substitution of modified cornflour was 3.63, 3.67, and 3.93 (like) respectively.

AbstractCoconut oil can be deteriorated by oxidation during storage and formed a rancid odor. The objective of the research is to evaluate coconut oil quality during storage by the addition of tocopherol as an antioxidant. The 11-12 months of coconut fruits harvested from Mapanget Tall coconut are used as raw materials. The oil is extracted by the wet method, and it was then formulated by the addition of tocopherol as an antioxidant on various concentrations (0; 0.5; 1.0 and 1.5 % w/v). The oil samples were then stored at room temperature for 2 months and evaluated for their quality for 0, 2, 4, 6, and 8 weeks. The oils are measured for moisture, free fatty acids, peroxide value, and TBA value. The results of the research showed that the moisture of coconut oil is stable during storage with or without antioxidants. The addition of antioxidants affected the free fatty acid of coconut oil, whereas the oil without antioxidants having free fatty acid compared to others treated with antioxidants.

Abstract
Sugarcane is one of the important crops in the world. It can produce a broad range of valuable products in the area of food, health, agriculture, and bioplastic. However, sugarcane is vulnerable to Sporisorium scitamineum infection. The use of resistant varieties is believed to be a proper control method for the disease. The induced mutation is one of breeding program methods that can be considered to acquire resistant varieties of sugarcane to smut disease. In 2018, we did mutation for some sugarcane varieties then in 2019 the mutants were screened for their resistance to smut disease. This research aimed to identify the resistance character of sugarcane mutants to smut disease. The inoculation method was conducted by dipping the bud into S. scitamineum teliospore suspension for 10 minutes at 30 °C. The buds were then planted and maintained in the polybags. The results showed that out of 41 evaluated mutants, 11 mutants were highly resistant, 9 mutants were resistant, 8 mutants were susceptible and 13 mutants were highly susceptible to smut infection. It seems that we could obtain resistant sugarcane varieties through induced mutation, however the resistance of the cane is still being evaluated during the ratoon stage.

Abstract
Pesticide is poisonous compound containing synthetic chemicals and popularly used by farmers in crop management. The harmful synthetic chemicals contained in pesticides are capable of rapidly killing target organisms. However, the continuous use of pesticides killing natural enemies as the potential agent to control insect pests. Another risks the pesticide residues become the main source of environmental pollution. The research objective is to determine the behavior of farmers using pesticides in maize plantation. The research was conducted in Tenri Pakkua village, Lappariaja district, Bone Regency, South Sulawesi from January to March 2020. The research activity used a survey method in the form of interviews using a questionnaire to 35 respondent farmers. The results were showed about 97.15% of respondent control weeds using herbicides, about 2.85% of respondents control manual for the same weed. In addition, 62.86% of the respondent used herbicides for more than four years. The most insecticides used by respondents control insect pests in maize from the active ingredients: Permethrin (42.87%), Fipronil (14.29%), Lambda-cyhalothrin (11.44%) and Metomil (8, 58%). The results showed that farmers prefer use pesticides in the form of herbicides and synthetic insecticides because the results are visible, they quickly kill the target organism, the application does not require special skills and is easy to obtain (commercially available).
