Time-series metagenomics reveals changing protistan ecology of a temperate dimictic lake by Krinos, Arianna I., Bowers, Robert M., Rohwer, Robin R., McMahon, Katherine D., Woyke, Tanja, Schulz, Frederik

“…Our study identified long-term changes in the abundance of eukaryotic microbes and provided context for the known establishment of an invasive species that catalyzes a trophic cascade involving protists. Our findings are important for decoding potential long-term consequences of human interventions, including invasive species introduction.…”

Spatial structure of workplace and communication between colleagues: A study of E-mail exchange and spatial relatedness on the MIT campus by Sevtsuk, Andres, Chancey, Bahij, Basu, Rounaq, Mazzarello, Martina

“…Building on prior studies of both physical and electronic communication networks, we present the results of a study conducted on the MIT campus using an anonymized dataset of e-mail communication to examine how spatial relatedness between faculty, staff, and researchers’ office locations impact E-mail communication between them. Our findings suggest that (a) people whose offices are closer to each other by walking are more likely to exchange E-mails, (b) on the campus as a whole, people who are more likely to walk past each other’s offices on the way to or from work are more likely to exchange E-mails, and (c) people who share access to similar eating venues around their offices are more likely to exchange E-mails. …”

Predicting drivers’ route trajectories in last-mile delivery using a pair-wise attention-based pointer neural network by Mo, Baichuan, Wang, Qingyi, Guo, Xiaotong, Winkenbach, Matthias, Zhao, Jinhua

“…Results from an extensive case study on real operational data from Amazon’s last-mile delivery operations in the US show that our proposed method can significantly outperform traditional optimization-based approaches and other machine learning methods (such as the Long Short-Term Memory encoder–decoder and the original pointer network) in finding stop sequences that are closer to high-quality routes executed by experienced drivers in the field. …”

Ex Post Path Choice Estimation for Urban Rail Systems Using Smart Card Data: An Aggregated Time-Space Hypernetwork Approach by Mo, Baichuan, Ma, Zhenliang, Koutsopoulos, Haris N, Zhao, Jinhua

“…Solving the decomposed problem is equivalent to finding a fixed point. We prove that the solution to the original problem is the same as the decomposed problem (i.e., the fixed point) when passenger path choices follow the predefined behavior model. …”

Spectroscopic study of emergent electronic phases in transition metal based compounds by Song, Qian

“…We provide direct evidence that the spin polarization in a spin spiral type-II multiferroic exhibits p-wave (odd-parity) character and directly couples to the spin chirality, enabling electrical control of non-relativistic spin splitting. Our findings represent the first observation of a p-wave antiferromagnet, and open a new frontier of voltage-based switching of non-relativistic spin splitting in vdW antiferromagnets.…”

Dynamic Expansion and Merging of the Equatorial Ionization Anomaly During the 10–11 May 2024 Super Geomagnetic Storm by Aa, Ercha, Chen, Yanhong, Luo, Bingxian

“…The investigation utilizes multi-instrument datasets, including ground-based observations (GNSS TEC, ionosonde, and Fabry–Perot interferometer) as well as space-borne satellite measurements (GOLD, Swarm, DMSP, and TIMED). Our findings reveal significant day-to-day variations in the storm-time equatorial ionization anomaly (EIA), summarized as follows: (1) During the main phase of the storm, the low- and mid-latitude ionosphere experienced a positive storm, with TEC drastically enhanced by 50–100% within a few hours. …”

Nanostructured bimetallic sulfides as Na ion battery anodes by Chen, Jingwei

“…By combining ex-situ X-ray photoelectron microscopy and in-situ X-ray absorption spectroscopy, the electrochemical mechanism of CMS1 was also studied, revealing the intercalation dominant electrochemical reaction in ether-electrolyte while conversion occurred in carbonate-based electrolyte. These findings provide insights on the governing factors that explain the structural-electrochemical performance interplay of the bimetallic sulfides.…”

A first-principles study on the adsorption of small molecules on antimonene : oxidation tendency and stability by Kistanov, Andrey A., Cai, Yongqing, Kripalani, Devesh Raju, Zhou, Kun, Dmitriev, Sergey V., Zhang, Yong-Wei

“…Although the surface oxidation layer may serve as an effective passivation layer, preventing further degradation of the underlying layers, our findings show that the antimonene layers still need to be separated or properly protected by other noncovalent functionalization from oxygen or other environmental molecules. …”

Assessing translation qualities of online catchwords in Chinese by taking translators’ bilingual and cultural backgrounds as affecting factors by Ji, Xinru

“…It is also shows that there is a need for Singaporeans to balance their levels of Chinese and English and that the biggest difficulty for Singaporean participants is not the language, but finding the cultural equivalence in other culture. …”

Effects of plant functional group removal on CO2 fluxes and belowground C stocks across contrasting ecosystems by Grau-Andrés, Roger, Wardle, David A., Gundale, Michael J., Foster, Claire N., Kardol, Paul

“…Our results show that the effect of plant functional group diversity on C dynamics can be relatively consistent across contrasting ecosystems that vary greatly in productivity and soil fertility. These findings underline the key role of understory vegetation in forest C cycling, and suggest that global change leading to changes in the relative abundance of both shrubs and mosses could impact on the capacity of boreal forests to store C.…”

Legal translation and ISO standards : a case study by See, Tingting

“…The results showed that ISO certified LSPs do produce legal translations of better quality. The findings also showed that patrons are willing to pay more for quality legal translation and that patrons tend to have higher expectations of legal translation which is meant to be legally binding as opposed to one for reference only.…”

Modernity and functionality: relooking changes in Chinese vernacular education in Singapore, 1919-1941 by Ho, Amanda Shi Min

“…This thesis aims to reconstruct the history of modern Chinese schools in Singapore from 1919 to 1941, reexamining what has been covered thus far in both English and Chinese scholarship of the history of Chinese vernacular education in Singapore and synthesising the findings of both strands of scholarship. This thesis also aims to look beyond the study of political time markers to draw out the possible socio-cultural and economic factors that led to these changes.…”
