Introduction

In recent years, growing attention has been directed toward the greenhouse effect and its role in global warming. The primary greenhouse gases (GHGs) contributing to this phenomenon are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases act like a blanket around the Earth, trapping heat by absorbing energy and delaying its escape back into space. This process leads to a gradual increase in global temperatures, threatens livestock production. This climate change-induced stress impacts feed crop and forage quality, water availability, milk yield, animal health, reproduction, and overall biodiversity (Rojas-Downing et al., 2017). To cap global warming at 1.5°C above pre-industrial levels by 2050 as outlined by the IPCC (2018), global net-zero emissions are essential, coupled with drastic cuts in methane emissions (Rogelj and Lamboll, 2024). Methane stands out as a particularly potent contributor. It absorbs more heat per molecule than CO2 and has a global warming potential (GWP) 28 times higher over a century. Additionally, methane indirectly contributes to global warming as a precursor to ozone, another harmful GHG (Kataria, 2015). The rising levels of atmospheric methane are closely tied to human activities, such as agriculture and fossil fuel production, with anthropogenic sources accounting for about two-thirds of total emissions.

Extended-spectrum Beta-lactamase producing Enterobacteriaceae in clinical specimens at selected Microbiology Laboratories, Addis Ababa, Ethiopia
Creators: name: Shiferaw, Dejenie
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: The current estimated number of deaths worldwide due to drug-resistant infections is about 700,000 each year. The emergence and spread of Extended-spectrum beta-lactamases (ESBLs) producing Enterobacteriaceae becomes one of the serious health problems globally. Objective: To determine the magnitude of Extended-spectrum beta-lactamase producing Enterobacteriaceae (ESBLs-E) in different clinical specimens at selected microbiology laboratories, Addis Ababa, Ethiopia. Methods: A cross-sectional study was conducted from January 1 to May 30, 2017. A total of 426 Enterobacteriaceae isolates were collected from four bacteriology laboratories using tryptose soya broth with 20% glycerol. Fresh colonies of the isolates were recovered using MacConkey and 5% sheep blood agar plate. Antimicrobial susceptibility testing was performed on Muller Hinton agar. All Enterobacteriaceae were screened for ESBLs production using cefotaxime and ceftazidime as per Clinical and Laboratory Standards Institute (CLSI) guideline. Each ESBLs specious Enterobacteriaceae were confirmed by combination disk test (CDT) and double disk synergy test (DDST). The sensitivity, specificity, positive and negative predictive value of DDST was calculated. Data was entered and analyzed using SPSS version 20. Results: The most frequent Enterobacteriaceae were E. coli 228 (53.5%) and K. pneumoniae 103 (24.1 %). The magnitude of ESBLs-E was 246 (57.7%) by CDT and 224 (52.6%) by DDST. The highest frequencies of ESBLs-E were observed in blood specimen (84.4%) (P < 0.05) and the highest ESBLs production was observed in K. pneumoniae (85.4%). Highest resistance level was seen to sulfamethoxazole-trimethoprim (77.0%), augumentin (71.6%), cefotaxime (62.2%), cefepime (60.3) and ceftazidime (60.8%). The resistance to meropenem, amikacin and cefoxitin were 5.2%, 13.8% and 25.1% respectively. The overall magnitude of multi-drug resistance (MDR) level was 68.3%. Of ESBLs-E, 96.3% were MDR (P < 0.05). The sensitivity, specificity, PPV and NPV of DDST was 91.1%, 100%, 100% and 46.3% respectively. Conclusion: There was a high magnitude of ESBLs producing Enterobacteriaceae and MDR. Hence, the control of ESBLs should be a high priority. The better antibiotics for ESBLs producing Enterobacteriaceae were meropenem and amikacin. ESBLs detection by DDST routinely can help for infection control and timely treatment of a patient with best antibiotics.

description: Recent surveys of marine plastic debris density have revealed high levels in the center of the subtropical gyres. Earlier studies have argued that the formation of great garbage patches is due to Ekman convergence in such regions. In this work we report a tendency so far overlooked of drogued and undrogued drifters to accumulate distinctly over the subtropical gyres, with undrogued drifters accumulating in the same areas where plastic debris accumulate. We show that the observed accumulation is too fast for Ekman convergence to explain it. We demonstrate that the accumulation is controlled by finite-size and buoyancy (i.e., inertial) effects on undrogued drifter motion subjected to ocean current and wind drags. We infer that the motion of flotsam in general is constrained by similar effects. This is done by using a newly proposed Maxey--Riley equation which models the submerged (surfaced) drifter portion as a sphere of the fractional volume that is submerged (surfaced).

description: It is usually considered that the spectrum of an optical cavity coupled to an atomic medium does not exhibit a normal-mode splitting unless the system satisfies the strong coupling condition, meaning the Rabi frequency of the coherent coupling exceeds the decay rates of atom and cavity excitations. Here we show that this need not be the case, but depends on the way in which the coupled system is probed. Measurements of the reflection of a probe laser from the input mirror of an overdamped cavity reveal an avoided crossing in the spectrum which is not observed when driving the atoms directly and measuring the Purcell-enhanced cavity emission. We understand these observations by noting a formal correspondence with electromagnetically-induced transparency of a three-level atom in free space, where our cavity acts as the absorbing medium and the coupled atoms play the role of the control field.

description: Jet substructure observables, designed to identify specific features within jets, play an essential role at the Large Hadron Collider (LHC), both for searching for signals beyond the Standard Model and for testing QCD in extreme phase space regions. In this paper, we systematically study the structure of infrared and collinear safe substructure observables, defining a generalization of the energy correlation functions to probe $n$-particle correlations within a jet. These generalized correlators provide a flexible basis for constructing new substructure observables optimized for specific purposes. Focusing on three major targets of the jet substructure community---boosted top tagging, boosted $W/Z/H$ tagging, and quark/gluon discrimination---we use power-counting techniques to identify three new series of powerful discriminants: $M_i$, $N_i$, and $U_i$. The $M_i$ series is designed for use on groomed jets, providing a novel example of observables with improved discrimination power after the removal of soft radiation. The $N_i$ series behave parametrically like the $N$-subjettiness ratio observables, but are defined without respect to subjet axes, exhibiting improved behavior in the unresolved limit. Finally, the $U_i$ series improves quark/gluon discrimination by using higher-point correlators to simultaneously probe multiple emissions within a jet. Taken together, these observables broaden the scope for jet substructure studies at the LHC.

description: By means of a finite elements technique we solve numerically the dynamics of an amorphous solid under deformation in the quasistatic driving limit. We study the noise statistics of the stress-strain signal in the steady state plastic flow, focusing on systems with low internal dissipation. We analyze the distributions of avalanche sizes and durations and the density of shear transformations when varying the damping strength. In contrast to avalanches in the overdamped case, dominated by the yielding point universal exponents, inertial avalanches are controlled by a non-universal damping dependent feedback mechanism; eventually turning negligible the role of correlations. Still, some general properties of avalanches persist and new scaling relations can be proposed.

Assessment of Serum Gamma Glutamyl Transferase Enzyme Activities among Patients with Cardiovascular Diseases Attending Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia
Creators: name: Jemal, Kiyar
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Gamma-Glutamyl Transferase (GGT) is an enzyme located on the external surface of membranes of various cells. The most important physiological function of GGT is for the extracellular catabolism of glutathione. These catabolism produces the reactive thiol cysteinyl-glycine moiety which causes the reduction of Fe3+ to Fe2+, thus starting an Fe dependent redox-cycling process resulting in the production of the reactive oxygen species particularly O2* and H2O2, both capable of stimulating pro-oxidant reactions which cause atherosclerosis. Cardiovascular diseases are a group of disorders that include diseases of the heart and blood vessels or both. Objective: To assess serum gamma glutamyl transferase enzyme activities among patients with cardiovascular diseases attending Tikur Anbessa specialized hospital, Addis Ababa Ethiopia. Methodology: A comparative cross-sectional study was conducted on 103 participants from Feb. –May 2018 at TASH cardiology unit. The sociodemographic data were collected using well-structured questionnaire. Other additional information, records, and history was taken from participant medical records on working checklist. Venous blood specimens were collected from the participant according to standard guidelines and used to measure serum level of GGT using spectrophotometric techniques. Descriptive analysis, correlation, and chi square, independent sample T-test, one way ANOVA analysis were used for this study. All continuous data's were expressed in mean ± SD. Results: Among the total study participants 50.5% were male and within age range of 20-78 years. The mean GGT level among CVDs patients (36.2 ± 24.34 U/L) was found statistically and significantly higher than control subjects (26.5 ± 12.9 U/L) with P value of 0.013. GGT level had statistically significant strong and positive correlation with FBS (r=0.206 p = 0.037) and TG (r=0.351 p<0.001). GGT was further positively correlated with TC (r = 0.017), LDL-C (r = 0.121), DBP (r = 0.09), SBP (r = 0.16). Reversely, serum GGT was negatively correlated (r=-0.057) to HDL-C level. Conclusion: Higher level of serum GGT in the CVDs patients was noted. Participants with atherosclerotic risk factors such as diabetes, hypertension and dyslipidemia had significant higher serum GGT level compared to those without these factors.

Agroforestry in India: Status, Potential, and Challenges
Creators: name: Akshay Kumar, Shivani Verma
Publisher: name: The Science world a Monthly e magazine
Year: 2024

description: Agroforestry, which integrates woody perennials with crops and/or animals on the same land management unit, is a sustainable land-use system that offers ecological and economic benefits. This practice, which bridges agriculture and forestry, is essential in meeting India's goal of maintaining 33% forest cover, as per the National Forest Policy.

Current Status of Agroforestry in India

Agroforestry in India covers approximately 25.32 million hectares, or 8.2% of the country’s total geographical area (Dhyani et al., 2013); (Dagar et al. 2014) and (CAFRI, 2015). Despite being practiced across various agro-climatic zones, accurate monitoring of agroforestry areas remains a challenge due to inconsistent methodologies. Agroforestry systems in India are diverse, reflecting the country’s varied climates, and range from traditional methods like shifting cultivation to modern systems like plantation-based cropping.

Benefits of Agroforestry

Agroforestry offers multiple benefits, such as enhancing soil fertility, improving water conservation, and providing raw materials for industries. It also contributes to food security by producing fruits, nuts, and fodder. Additionally, agroforestry plays a crucial role in mitigating climate change through carbon sequestration. The Intergovernmental Panel on Climate Change (IPCC) recognizes agroforestry as a key strategy in reducing greenhouse gas emissions (Chavan et al. 2015).

The economic benefits of agroforestry are significant. It provides direct cash benefits from the sale of tree products and increased productivity per unit of land compared to monoculture systems. Moreover, agroforestry supports diversified products, including timber, fuelwood, and fruits, which are essential for rural livelihoods.

Search for dark matter in proton-proton collisions at 8 TeV with missing transverse momentum and vector boson tagged jets
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search is presented for an excess of events with large missing transverse momentum in association with at least one highly energetic jet, in a data sample of proton-proton collisions at a centre-of-mass energy of 8 TeV. The data correspond to an integrated luminosity of 19.7 inverse femtobarns collected by the CMS experiment at the LHC. The results are interpreted using a set of simplified models for the production of dark matter via a scalar, pseudoscalar, vector, or axial vector mediator. Additional sensitivity is achieved by tagging events consistent with the jets originating from a hadronically decaying vector boson. This search uses jet substructure techniques to identify hadronically decaying vector bosons in both Lorentz-boosted and resolved scenarios. This analysis yields improvements of 80% in terms of excluded signal cross sections with respect to the previous CMS analysis using the same data set. No significant excess with respect to the standard model expectation is observed and limits are placed on the parameter space of the simplified models. Mediator masses between 80 and 400 GeV in the scalar and pseudoscalar models, and up to 1.5 TeV in the vector and axial vector models, are excluded.

複数事象の提示が変数の同定に及ぼす効果の検討

Subjects: subject: Education

description: 自然科学において，変わり得る値を取る任意の要素を変数（variable）と呼ぶ。変数にはいくつかの種類があり，何も影響を受けずに独立に変化する要素を独立変数（independent variable），独立変数の影響を受けて変化する要素を従属変数（dependent variable）と呼ぶ。一般に，自然現象に内在する変数を同定することができなければ測定を行うことができないことから，変数を同定する活動は科学的探究の中でも実験活動の基礎を形成する中心的なプロセスである（大嶌，2015）。同様に，理科教育においても変数の同定は重要であり，変数が同定されることによって，問題や仮説を定式化することが可能となり，実験において統制するべき変数が明確になる。これまで理科教育の研究では，問いの設定（吉田・川崎, 2019），仮説設定（中村・松浦, 2018），条件制御（Tschirgi, 1980）といった様々な過程で，変数を同定する思考操作が行われていることを確認してきた。しかしながら，変数の同定は複雑な認知処理であり，学習者にとって難易度の高いことも報告されている（Arnold et al., 2018; Piekny & Maehler, 2012）。 学習者の変数の同定を支援する方法として，佐久間・中村（2021）は，複数事象の比較に基づくアプローチを実践している。このアプローチでは，一部の条件が異なる複数の事象を学習者に提示し，事象間で何が違うかを比較するよう求めることで，事前知識の乏しい学習者であっても変数を同定できるよう工夫している。従来の一般的な理科授業では単一の事象を示して変数を同定していたのに対して，佐久間・中村（2021）は複数の事象を用いている点が異なる。これまでの研究では，複数事象の比較が変数の同定を促進することが示唆されているが，そのメカニズムまでは明らかになっていない。とりわけ，提示する事象の数が単一と複数の場合で，学習者の変数の同定にどのような違いが生じるかについてはこれまで検討されてこなかった。 そこで，本研究では，提示する事象の数によって，学習者の変数の同定にどのような違いが生じるかを明らかにすることを目的とする。

description: Background: In Gram negative pathogens, beta-lactamase (β-lactamases) production remains the most important mechanism of antimicrobial resistance. These β-lactamases includes Extended spectrum Beta-lactamases (ESBL), AmpC β-lactamases (AmpC) and Carbapenemases. Objective: To determine the Magnitude of ESBL, AmpC β-lactamases and Carbapenemase producing gram negative bacilli (GNB) isolated from clinical specimens at International Clinical Laboratories, Addis Ababa, Ethiopia. Methods: A cross sectional study was carried out on 338 GNB isolates between January to May 2018. The bacteria were isolated from urine, wound, body fluids, sputum, stool, ear and eye discharge using 5% sheep blood agar, MacConkey, Xylose lysine deoxycholate and chocolate agar plates. Bacterial species identification, antimicrobial susceptibility testing and β-lactamases screening were performed using Phoenix system. Potential carbapenemase producers were confirmed by Modefied Hodge test and KPC, MBL, OXA-48 were phenotypically characterized by disc diffusion method. Cefoxitin resistant bacteria were confirmed for AmpC β-lactamases production by AmpC confirmatory disc. ESBLs production was confirmed using a combination disc method. Data was entered and analyzed using SPSS version 20 software. Results: The predominant GNB was E. coli 66.0% (n=224) followed by K. pneumoniae 12.1% (n=41). The magnitude of β-lactamases producing GNB was 43.0% (n=144). The overall magnitude of ESBL producing GNB was 38.8% (n=131) while, carbapenemase and AmpC β-lactamases producing GNB were 1.2% (n=4) and 2.4% (n=8) respectively. The majority of β-lactamases producing GNB were isolated from urine specimen 47.5% (n=116). Highest resistance level was seen to ampicilline (75.4%), augumentin (64.0%) and sulfamethoxazole-trimethoprim (55.6%). Multidrug resistance (MDR) level was 73.7%. Of β-lactamases producing GNB, 99.3% were MDR (P < 0.05). Conclusion: The magnitude of β-lactamases producing GNB and MDR were high. Therefore, the emergence of β-lactamases producing GNB requires continuous monitoring & reviewing of antimicrobial policy in hospitals and the country at large. Amikacin, meropenem and imipenem were the most effective antibiotics against β-lactamases producing GNB.

description: The unsteady response of a water free surface to a localized pressure source moving at constant speed $U$ in the range $0.95c_\mathrm{min} \lesssim U \leq 1.02 c_\mathrm{min}$, where $c_\mathrm{min}$ is the minimum phase speed of linear gravity-capillary waves in deep water, is investigated through experiments and numerical simulations. This unsteady response state, which consists of a V-shaped pattern behind the source and features periodic shedding of pairs of depressions from the tips of the V, was first observed qualitatively by Diorio et al. (Phys. Rev. Let., 103, 214502, 2009) and called state III. In the present investigation, cinematic shadowgraph and refraction-based techniques are utilized to measure the temporal evolution of the free surface deformation pattern downstream of the source as it moves along a towing tank, while numerical simulations of the model equation described by Cho et al. (J. Fluid Mech., 672, 288-306, 2011) are used to extend the experimental results over longer times than are possible in the experiments. From the experiments, it is found that the speed-amplitude characteristics and the shape of the depressions are nearly the same as those of the freely propagating gravity-capillary lumps of inviscid potential theory. The decay rate of the depressions is measured from their height-time characteristics, which are well fitted by an exponential decay law with an order 1 decay constant. It is found that the shedding period of the depression pairs decreases with increasing source strength and speed. As the source speed approaches $c_\mathrm{min}$, this period tends to about 1~s for all source magnitudes. At the low-speed boundary of state III, a new response with unsteady asymmetric shedding of depressions is found. This response is also predicted by the model equation.

description: Background:Hemoglobin concentration is measured routinely using automated hematology analyzers. Even if these automated hematology analyzers are very accurate and reliable, they are expensive and transport of the samples to the laboratory delays the process which may delay treatment. Point of care hemoglobin analyzer like Hemocue301+ has potential to solve such problems. Although method comparison experiment has to be conducted when new instrument are installed, this practice is not common in our country. Objective:To compare hemoglobin determined by Hemocue301+, with Sysmex-kx21N and Cell-Dyn1800 methods using patients' blood sample at St Paul's Specialized Hospital Millennium Medical College in Addis Ababa, Ethiopia. Methods:A facility based cross sectional study with convenient sampling method was conducted at St. Paul's specialized teaching hospital starting from May 15 to June 2 2015. A total of 117specimens for agreement study and 3 specimens for precision study were analyzed on Hemocue301+, Sysmex-Kx21N, and cell-Dyn1800 hematology analyzers to compare their Hemoglobin results. This study includes patients of all age group. One sample t-test and bland and Altman plot with limit of agreement were used to make inference. Data analyses were performed using SPSS version 20 Software. Result:The precision experiment showed within run normal range CV% for Hemocue301+, SysmexKx21N and Cell-Dyn1800 (1.7%, 1.3%, 1.8%, respectively). The one sample t-test showed a non-significant p-value of 0.10 for Hemocue301+ and Sysmex-Kx21N and the limit of agreement from Bland and Altman plot for 95% was (-1.07, 1.25)g/dl with only 1.7% of the cases were out of the limit of agreement. For Hemocue301+ and Cell-Dyn1800, a non-significant p- value of 0.46 and the Bland and Altman plot limit of agreement for 95% was (-1.22, 1.31)g/dl with only 1.7%of the case were out of the limit of agreement.Hemocue301+was agreed with SysmexKx21N and Cell-Dyn1800 within 1 g/dl which was considered as clinically important limit for Hemoglobin measurement. Conclusion: The Hemocue301+ maybe used interchangeably with Sysmex-Kx21N and Cell- Dyn1800 automated Hematology analyzers in St Paul's Specialized Hospital Millennium Medical College Hematology laboratory

description: We use the concept of reproducing pairs to study Gabor systems at critical density. First, we present a generalization of the Balian-Low theorem to the reproducing pairs setting. Then, we prove our main result that there exists a reproducing partner for the Gabor system of integer time-frequency shifts of the Gaussian. In other words, the coefficients for this Gabor expansion of a square integrable function can be calculated using inner products with an unstructured family of vectors in $ L^2(\R)$. This solves the possibly last open question for this system.

description: The FoxP family of transcription factors is necessary for operant self-learning, an evolutionary conserved form of motor learning. The expression pattern, molecular function and mechanisms of action of the Drosophila FoxP orthologue remain to be elucidated. By editing the genomic locus of FoxP with CRISPR/Cas9, we find that the three different FoxP isoforms are expressed in neurons, but not in glia and that not all neurons express all isoforms. Furthermore, we detect FoxP expression in, e.g. the protocerebral bridge, the fan-shaped body and in motor neurons, but not in the mushroom bodies. Finally, we discover that FoxP expression during development, but not adulthood, is required for normal locomotion and landmark fixation in walking flies. While FoxP expression in the protocerebral bridge and motor neurons is involved in locomotion and landmark fixation, the FoxP gene can be excised from dorsal cluster neurons and mushroom-body Kenyon cells without affecting these behaviours.

description: What is a T2T assembly?

Telomere-to-Telomere (T2T) assembly refers to the complete sequencing and assembly of a genome from one end of a chromosome (telomere) to the other. T2T assemblies are free of gaps, capturing even the most difficult-to-sequence regions, including centromeres and highly repetitive sequences. They provide an unprecedented level of accuracy and completeness in genome sequencing. These were made possible with the introduction of long read sequencing technologies like PacBio HiFi and Oxford Nanopore Technologies (ONT)

description: Dear Editor,Before docking NAD+ with PEP, we validated PEP's stability through a 200 ns molecular dynamics simulation using Desmond in Schrödinger Maestro v2024.4. Optimization involved removing distant water molecules and minimizing RMSD. The system was equilibrated using the NPT ensemble, and simulations were repeated for reproducibility. Following stability confirmation, we evaluated PEP's potential as an ADP-ribosylating protein through molecular screening with PyRx. All data are available in File S4.

description: Constrained energy minimizations of a many-body Hamiltonian return energy landscapes e(b) where b= representes the average value(s) of one (or several) collective operator(s), B, in an "optimized" trial state Phi_b, and e = is the average value of the Hamiltonian in this state Phi_b. It is natural to consider the uncertainty, Delta e, given that Phi_b usually belongs to a restricted set of trial states. However, we demonstrate that the uncertainty, Delta b, must also be considered, acknowledging corrections to theoretical models. We also find a link between fluctuations of collective coordinates and convexity properties of energy surfaces.

description: The condensed isotopic modifications of methane, CH4, CH2D2, and CD4 and their solutions with Kr were investigated using dielectric techniques. The polarizabilities were computed from the permittivities of the pure liquids. Phase diagrams of methane-krypton alloys were deduced in the liquid-solid coexistence region and for the low temperature phases (T<30 K). From the Curielaws, which described the permittivities of the (Kr)1-x(CH2D2)x mixed crystals, the permanent dioole moment of CH2D2 is calculated to be 4 mD. In the octopolar ordered phases of the solid solutions the effective dipole moments are enhanced significantly.
Spin Chains as Perfect Quantum State Mirrors

description: Quantum information transfer is an important part of quantum information processing. Several proposals for quantum information transfer along linear arrays of nearest-neighbor coupled qubits or spins were made recently. Perfect transfer was shown to exist in two models with specifically designed strongly inhomogeneous couplings. We show that perfect transfer occurs in an entire class of chains, including systems whose nearest-neighbor couplings vary only weakly along the chain. The key to these observations is the Jordan-Wigner mapping of spins to noninteracting lattice fermions that display perfectly periodic dynamics if the single-particle energy spectrum is appropriate. After a half-period of that dynamics, any state is transformed into its mirror image with respect to the center of the chain. The absence of fermion interactions preserves these features at an arbitrary temperature and allows for the transfer of nontrivially entangled states of several spins or qubits.

description: Rotating bodies in General Relativity produce frame dragging, also known as the {\it gravitomagnetic effect} in analogy with classical electromagnetism. In this work, we study the effect of magnetic field on the gravitomagnetic effect in neutron stars with poloidal geometry, which is produced as a result of its rotation. We show that the magnetic field has a non-negligible impact on frame dragging. The maximum effect of the magnetic field appears along the polar direction, where the frame-dragging frequency decreases with increase in magnetic field, and along the equatorial direction, where its magnitude increases. For intermediate angles, the effect of the magnetic field decreases, and goes through a minimum for a particular angular value at which magnetic field has no effect on gravitomagnetism. Beyond that particular angle gravitomagnetic effect increases with increasing magnetic field. We try to identify this `null region' for the case of magnetized neutron stars, both inside and outside, as a function of the magnetic field, and suggest a thought experiment to find the null region of a particular pulsar using the frame dragging effect.

description: Since the discovery of large, non-saturating magnetoresistance in bulk WTe2 which allows microexfoliation, single- and few-layer WTe2 crystals have attracted increasing interests. However, as it mentioned in existing studies, WTe2 flakes appear to degrade in ambient conditions. Here we report experimental observations of saturating degradation in few-layer WTe2 through Raman spectroscopy characterization and careful monitoring of the degradation of single-, bi- and tri-layer (1L, 2L & 3L) WTe2 over long time. Raman peak intensity decreases during WTe2 degradation and 1L flakes degrade faster than 2L and 3L flakes. The relatively faster degradation in 1L WTe2 could be attributed to low energy barrier of oxygen reaction with WTe2. We further investigate the degradation mechanisms of WTe2 using XPS and AES and find that oxidation of Te and W atoms is the main reason of WTe2 degradation. In addition, we observe oxidation occurs only in the depth of 0.5nm near the surface, and the oxidized WTe2 surface could help prevent inner layers from further degradation.
