Fit-free analysis of fluorescence lifetime imaging data using chemometrics approach for rapid and nondestructive wood species classification
Authors: Ma Te , Inagaki Tetsuya , Tsuchikawa Satoru 
Published: August 2023

Abstract
Conventional fluorescence spectroscopy has been suggested as a valuable tool for classifying wood species rapidly and non-destructively. However, because it is challenging to conduct absolute emission intensity measurements, fluorescence analysis statistics are difficult to obtain. In this study, another dimension of fluorescence, that is, fluorescence lifetime, was further evaluated to address this issue. A time-resolved fluorescence spectroscopic measurement system was first designed, mainly using a streak camera, picosecond pulsed laser at 403 nm, and a spectroscope, to collect the fluorescence time-delay (FTD) profiles and steady-state fluorescence intensity (FI) spectra simultaneously from 15 wood species. For data analysis, principal component analysis was used to “compress” the mean-centered FTD and FI spectra. Then, support vector machine classification analysis was utilized to train the wood species classification model based on their principal component scores. To avoid overfitting, ten-fold cross-validation was used to train the calibration model using 70 % of the total samples, and the remaining 30 % hold-out validation was used to test its reproducibility. The cross-validation accuracies were 100 % (5 softwoods) and 96 % (10 hardwoods), with test-validation accuracies of 96 % and 89 %.

Published: August 2023

Abstract
The numerical simulation length of the cassette model is determined by studying the effects of the cassette frame rotated alone and the rotated together with the agitator on mixing under different cassette lengths. The effects of different rotating speed, filling ratio of silicon particles, shape and number of agitators on the mixing characteristics of silicon particles in the cassette are studied when the outer frame of the cassette rotated alone and the cassette rotated together with the agitator. The mixing degree is quantitatively analyzed by particle trajectory, mixing index and rate, and the optimum working conditions of each influencing parameter are obtained. The results show that considering the computation time and the influence of the two motion modes on the mixing index and rate, the numerical simulation length of the cassette model is 115 mm. In order to obtain the best mixing effect and mixing speed, it is recommended that the rotating speed of the cassette is 8.91 rad/s, the filling rate is 23.60 %, and the shape of the agitator is rectangular and the number is 6. When the cassette and agitator rotate together, the filling rate has little effect on particle mixing. Considering the production efficiency, mixing effect and rate, as well as the stability of mixing, the recommended speed is 4.08 rad/s, the filling rate is 41.40 %, and the rectangular shape and number of six agitators are ideal choices.
On Moving Past the ABCs

Abstract
Craig Callender’s What Makes Time Special? (OUP 2017) advocates and practices an innovative, thoroughly interdisciplinary approach to philosophical questions about time and temporal features of our lives. Grappling with it is of intrinsic philosophical interest; it is also part of responding to the methodological invitation the book issues to philosophers of time. This paper is motivated by the wish to clarify WMTS’s philosophical underpinnings. The main claim of the paper is that WMTS relies on an ambiguity between rejecting the A-theory versus B-theory debate, and endorsing a position within that debate. This ambiguity leads to a somewhat unstable position on how a key feature of manifest time, namely our sense of time as flowing, arises from physical time. The paper ends with a suggestion for how to resolve the ambiguity, in a way that is in line with the gist of Callender’s overall vision for the field.

Published: August 2023

Abstract
Orange-fleshed sweet potato (OFSP), a promising crop for alleviating vitamin A deficiency (VAD), can be utilized at home and in commercial food processing as a basic and functional ingredient. The root can be processed into puree that is incorporated in baked and fried products and other products, with a high acceptability rate. When used as a wheat substitute in a bakery, the OFSP puree significantly cuts the production cost. In the last few years and with the intensified promotion of OFSP and OFSP puree products as a sustainable food-based strategy to tackling VAD at the population level, many small-medium food enterprises (SMEs) in the Eastern Africa Region (EAR) have shown great interest in utilizing the OFSP puree in their commercial product lines. However, the OFSP and OFSP puree value chain for commercial usage is still underdeveloped poising raw material supply challenges. In addition, the SMEs are early-stage businesses lacking the capacity and proper business models to propel them to sustainably venture into OFSP processing. As such, there is a need to engage and support SMEs in tailoring business models suitable for their scaling needs along the OFSP value chain to make available in the market, affordable nutrient-dense OFSP-puree products. This article presents the approach that was used to offer tailored Business Development Services (BDS) for selected SMEs in EAR to scale up their capacity to commercialize OFSP puree and puree-based products. The BDS designed and supported six integrated modules: business profile development, business model canvas, understanding the numbers/finances, OFSP value chain analysis, SWOT analysis, and growth plan, to develop and document individual business capacities and aspirations. The SMEs identified numerous opportunities and entry points for OFSP value chain development and expansion through the BDS depending on their business needs.

Published: August 2023

Abstract
Cochlear implants are hearing prostheses for patients with severe to total hearing loss but intact auditory nerve. An external speech processor captures sound from the environment, which is subsequently converted into electrical signals and transmitted to an electrode array in the patient’s inner ear. The metallic stimulation electrodes of the electrode array electrically stimulate the spiral ganglion cells of the auditory nerve. The functionality of cochlear implants strongly depends on the possible maximum current stimulating the spiral ganglion cells, which can be affected by, e.g., cell growth around the stimulation electrodes. This in turn decreases the stimulation efficiency leading to decreased hearing. Cell growth, implant position and other changes in the surrounding medium are reflected in a change of the impedance of the stimulation electrodes. The impedance measurement of the stimulation electrodes is already implemented in all common cochlear implant systems to check functionality of the stimulation electrodes after implantation, but the frequency spectrum is normally not analyzed. Although this method can detect cell growth on the stimulation electrodes, it faces limitations when other interfering effects, such as changes in the perilymph and implant position, influence the impedance. This work shows impedance spectroscopic measurements using enlarged cochlear implant models to electrically analyze the surrounding medium, the perilymph, to understand changes in electrode impedance and to later monitor the stimulation efficiency of cochlear implants and to identify possible reasons for decreased hearing ability by impedance spectroscopy. In addition, we use FEM simulations to numerically model the influence of the perilymph composition on the impedance measurement. As shown by a final validation, this model can serve as a basis for an extended simulation model including implant position and cell growth monitoring to predict hearing deterioration in cochlear implant patients. In this context, this work serves as a basis for the development of a holistic prediction model and considers in the first step exclusively the influence of the perilymph composition on the impedance between two stimulation electrodes.
Effect of deposition potential and saccharin addition on structural, magnetic and magnetoresistance characteristics of NiCoFeCu films
Authors: Kuru Hilal , Köçkar Hakan , Alper Mürsel 
Published: August 2023

Abstract
NiCoFeCu films were electrodeposited on Ti substrates at different deposition potentials and different concentrations of saccharin added to solution. Compositional analysis showed that although Ni was the highest concentration in solution at low potentials of −1.0 V and −1.5 V, the Ni content was lower than the Co content in the films. Anomalous co-deposition behaviour of iron group metals was observed. When the deposition potential increased to −2.0 V and −2.5 V, the Ni content of films increased while the Co, Fe and Cu content decreased. In the case of saccharin addition to the solution, there is a slight change in the film content. All films have face-centred cubic structure. Structural analysis clearly showed that the potential has a significant effect on the texture degree of the films, since the crystal texture changed from (111) to (220) with increasing potential. The surface morphology of the films was observed to be affected by the deposition potential and saccharin concentration. For the magnetic analysis, saturation magnetisation, M
s value gradually decreased from 905 to 715 emu/cm3 with the variation of film content caused by the increase of the potential from −1.0 V to −2.5 V. And, a slight increase in M
s was detected with the addition of saccharin. Besides, the longitudinal and transverse magnetoresistance magnitudes increased from ∼2.5 % to 7.0 % with increasing deposition potential and all films exhibit anisotropic magnetoresistance. Films with desired magnetic properties can be obtained for potential use as magnetic materials in electronics such as magnetoresistive devices.

Published: August 2023

Este estudo versa sobre os erveiros do Mercado Ver-o-Peso, em Belém/PA, que dominam o saber das ervas,produzindo os produtos para cura dos males do corpo e da alma. Entretanto, o ofício das ervas tem seu valor enquanto alteridade local subjulgada, ao ser esse ofício representado como atrativo exótico autêntico, palatável ao fluxo turístico, visitado como uma vitrine do Ver-o-Peso, enquanto cartão postal. Portanto, este trabalho visa a rastrear a memória oral dos erveiros, bem como seus desdobramentos enquanto legado de resistência ao discurso hegemônico patrimonial e turístico do mercado. Metodologicamente, a pesquisa foi realizada antes e pós pandemia. Na primeira fase foi realizada análise qualitativa da natureza da arte dos erveiros, enquanto na segunda foi realizado um estudo etnográfico, concatenado com a história oral. Entre os resultados, foi possível discutir uma proposta alternativa de patrimônio, germinada pelos constructos antropológicos, em que o olhar dos erveiros enquanto “outros” é trazido para o centro do debate.
Preserved Metacognition for Undetected Visuomotor Deviations
Authors: Pereira Michael , Skiba Rafal , Cojan Yann , Vuilleumier Patrik , Bègue Indrit 
Published: August 2023

Humans can successfully correct deviations of movements without conscious detection of such deviations, suggesting limited awareness of movement details. We ask whether such limited awareness impairs confidence (metacognition). We recorded functional magnetic resonance imaging data while 31 human female and male participants detected cursor deviations during a visuomotor reaching task and rated their confidence retrospectively. We show that participants monitor a summary statistic of the unfolding visual feedback (the peak cursor error) to detect visuomotor deviations and adjust their confidence ratings, even when they report being unaware of a deviation. Crucially, confidence ratings were as metacognitively efficient for aware and unaware deviations. At the neural level, activity in the ventral striatum tracks high confidence, whereas a broad network encodes cursor error but not confidence. These findings challenge the notion of limited conscious action monitoring and uncover how humans monitor their movements as they unfold, even when unaware of ongoing deviations.SIGNIFICANCE STATEMENTWe are unaware of the small corrections we apply to our movements as long as our goals are achieved. Here, although we replicate the finding that participants deny perceiving small deviations they correct, we show that their confidence reliably reflects the presence or absence of a deviation. This observation shows they can metacognitively monitor the presence of a deviation, even when they deny perceiving it. We also describe the hemodynamic correlates of confidence ratings. Our study questions the extent to which humans are unaware of the details of their movements; describes a plausible mechanism for metacognition in a visuomotor task, along with its neural correlates; and has important implications for the construction of the sense of self.

Published: August 2023

Abstract
The abundance of organic waste generated by agro-industrial activities leads to the need to find alternatives for adequate destinations for these. Composting is the most viable alternative due to its low cost, ease of operation and generation of a product with the possibility of economic exploitation. The objective of this work was to present the dynamics of the composting process in an organic waste processing plant in the municipality of Montenegro, RS, Brazil, as well as to present the results of chemical analyzes for the quantification of humic substances contained in the leachate resulting from the composting process. The results of the leachate revealed that it has high levels of humic substances (humic acids between 12.2 and 30.7%, fulvic acids between 12.2 and 45.5%) significantly higher than those found in the literature (9%). Leachate has humic characteristics desired for the preparation of a commercial product for use in agriculture and can be configured as an interesting extra income alternative for the economic health of the enterprise.

Supporting the HIV+ Mother With Breastfeeding in the United States: A Case Report
Authors: Rosenblum Nadine , Sturdivant Heather 
Published: August 2023

Introduction:The American Academy of Pediatrics and the United States Centers for Disease Control and Prevention recommend that women living with HIV (WLHIV) avoid breastfeeding or feeding their infant their own milk to eliminate the risk of HIV transmission via breast milk. Thus, lactation support for WLHIV to breastfeed has been poorly understood in high-income countries. However, the National Institutes of Health has released new perinatal HIV clinical guidelines supporting exclusive breastfeeding under specific conditions.Case Presentation:This case reviews lactation team support of a WLHIV desiring to breastfeed her infant.Management and Outcome:Cooperation and collaboration with several providers and departments through pregnancy, hospitalization, and postdelivery to provide counseling, helped this mother exclusively breastfeed her newborn for three months without vertical transmission of HIV.Discussion:Although challenging, International Board Certified Lactation Consultants are uniquely positioned to support WLHIV to experience their desired breastfeeding outcome for her and her infant.
Tejiendo el (lo) rururbano: una aproximación a los procesos de rururbanización en la ciudad intermedia de Tunja, Colombia
Authors: Bautista Vargas Andrés Felipe 
Published: August 2023

En la actualidad, la dinámica rururbana constituye cambios profundos en sus formas, expresiones y morfologías. Es un nuevo estado de lo urbano en lo rural donde confluyen tiempos, espacios y geografías de diversa naturaleza, pero donde lo rural prevalece. ¿Pero de qué manera se reescriben estos procesos? ¿Cuáles son esas vías de análisis? El presente documento analiza el espacio rururbano de Tunja-Cómbita-Oicatá, una zona testigo de cambios y nuevas configuraciones expuestas en patrones espaciales de rururbanización cada vez más presentes en sus áreas intersticiales. Para ello, se realizó un análisis multitemporal de imágenes Lansadt 4 (1980), Spot (2000), Landsat 7 (2009) y Google Maps, formato tiff (2019), a través de herramientas de sistemas de información geográfica (sig). Como principales resultados, se identifican procesos de ocupación urbana, para el caso de Tunja, superiores al 90%, y para los otros municipios del 70 y el 40% respectivamente. Este ensanche, en su mayoría generado por la ciudad, incide en la aparición de nuevo tejido urbano discontinuo, disperso, multipolar y de localización diversa e irrumpe en la dinámica local de estos territorios y sus geografías, desafiando sus características tradicionales, campesinas y agrarias e instalando otras.

Authors: Soetjipto Hartati , Febriyanti Teresa , Kristijanto Agus Ign. 
Published: August 2023

Cucurbitaceae is known as a source of vegetable oil that can be used in the fields of food, medicine, and cosmetics. Several studies showed that vegetable oil from the Cucurbitaceae contains squalene. Squalene is a high-economic value compound that was originally found in shark liver oil. This compound is proven to be very beneficial for health and cosmetics. The objectives of the study are to determine the fatty acid profile and squalene content of cucumber seed oil using the Gas Chromatography-Mass Spectrometry (GC-MS) method. Starting with the preparation of cucumber seeds by drying the clean seed in an oven at 60 0C for 1 hour, then the seeds were extracted using 2 methods namely maceration and a continuous extraction method with a soxhlet extractor. The yield of crude oil obtained by the soxhlet extractor is higher than maceration, which was 19.38 ± 0.94%, yellow colour, and distinct aroma, 2% water oil content; oil density of 0.96 g/mL; free fatty acid levels of 3.51%; an acid value of 4.97 mg NaOH/g oil; and peroxide value of 0.82 meq O2/g oil. The results of the GC-MS analysis showed that cucumber oil was composed of 3 main components namely palmitic acid, linoleic acid, and squalene.
Keywords: Cucumber seed oil, Cucumis sativus, fatty acids, squalene.

Authors: Torre Barrett B. , Pavano Colin , Connors John Patrick , Silver Jacob , Bellas Nicholas , Shekhman Mark , Solovyova Olga 
Published: August 2023

Case:
Implant failure after unicondylar knee arthroplasty (UKA) is a rare but well-described complication in the arthroplasty literature. However, there is a paucity of literature regarding rapid catastrophic failure of modern implant designs. This is a case report of 2 patients with early catastrophic failure of the tibial baseplate after UKA with a Stryker Restoris MultiCompartmental Knee System implant using Mako robotic assistance, both requiring revision to total knee arthroplasty.

Conclusion:
Improved awareness and understanding of early UKA tibial baseplate failure may help identify both patient and surgical risk factors that could help prevent further instances in the future.
Heterotopic Ossification Remodeling After Acetabular Surgery
Authors: Kent Suzanne E. , Ryan Scott P. 
Published: August 2023

Case:
A 30-year-old woman presented with a transverse plus posterior wall acetabular fracture and underwent operative fixation through a Kocher-Langenbeck approach. Shared decision was made for no heterotopic ossification (HO) prophylaxis. The patient developed symptomatic HO and was scheduled for resection, which was delayed because of the pandemic. She returned with interval remodeling of HO and symptom resolution. No surgery was required.

Conclusion:
HO is a common complication after acetabular injury. Resection is the treatment of choice for symptomatic HO. We are not aware of other reports of spontaneous remodeling of symptomatic HO such that it no longer required surgery.
In Situ Stabilization of the Ulnar Nerve as an Alternative to Transposition in Traumatic Ulnar Nerve Instability
Authors: Voerman Samgar Frederik , Degreef Ilse 
Published: August 2023

Case:
We present the case of a 25-year-old male sports climber treated with in situ ulnar nerve stabilization for ulnar nerve instability (UNI) by using 2 fascial flaps.

Conclusion:
Symptomatic UNI has traditionally been managed with subcutaneous or submuscular ulnar nerve transposition. Transposition is relatively invasive and when performed subcutaneously, embeds the ulnar nerve in an exposed location, which may render it prone to mechanical injury in physically active patients. In situ stabilization may be a less invasive alternative to transposition in select patients involved in sports such as rock climbing.

Published: August 2023

Case:
We describe a case of a traumatic superior dislocation of the sternoclavicular joint (SCJ) due to an isolated rupture of the costoclavicular ligament (CCL). A magnetic resonance imaging (MRI) scan demonstrated the CCL rupture with preservation of the anterior and posterior SCJ ligaments. This was successfully treated with an isolated hamstring tendon reconstruction of the CCL, resulting in a satisfactory outcome at 1 year after the procedure.

Conclusion:
Isolated CCL reconstruction with a hamstring tendon in a patient with a superior SCJ dislocation provided a satisfactory outcome.
